Technical Field

The utility model belongs to the field of packing machine equipment, and particularly relates to a wire feeding mechanism capable of opening and closing and a steel (reinforced bar) bundling machine using the wire feeding mechanism.

Background

In the traditional industry, the steel bars, the section steel and the like are often bundled by manually using simple tools, under the condition of manual labor, work fatigue of staff is easily caused due to high working strength, work injury is likely to occur, safety production is not good, bundling efficiency is low, and bundling quality is low. To solve these problems, some bar binding apparatuses such as "bar binding machine and binding method" of chinese patent application (application number CN2010105702801, application date 12/02/2010, authorized bulletin date 2012/8/15) are on the market, but these apparatuses have the following problems: (1) The binding tightening force is insufficient due to insufficient gripping force on the packing steel wires, so that binding is loose; (2) the steel wire for bundling is easy to wind and coil when feeding the steel wire; (3) The wire for bundling lacks the design associated with automatic wire feeding.

In order to solve the problems of the traditional industry and the existing steel bar bundling machine, related cooperators develop a Chinese patent 'full-automatic manipulator steel bar bundling machine' (application number 2015103507968, application date 2015, 6, 23, and authorized bulletin date 2017, 12, 26) and 'a steel bar bundling machine based on a driven opening and closing clamp splice device' (application number 2016102833451, application date 2016, 4, 28, and authorized bulletin date 2018, 5, 11).

The utility model patent of China with the publication number of CN104925293B discloses a steel bar bundling device named as a full-automatic manipulator steel bar bundling machine, the utility model realizes bundling of steel bar bundles through the cooperation of a lower wire threading straightening workbench and a rotary clamping mechanical claw, the lower wire threading straightening workbench consists of a base, a wire disorder frame, a roller type straightener, a hydraulic shear, an opening and closing guide pipe and a stand column, and the opening and closing guide pipe consists of a jacking hydraulic cylinder, a four-bar mechanism and a guide pipe (the jacking hydraulic cylinder can control the opening and closing state of the guide pipe through the four-bar mechanism); during operation, the lower wire threading straightening workbench is responsible for penetrating the steel wire for bundling through the bottom of the steel bar bundle and penetrating into the rotary clamping mechanical claw (at the moment, the opening and closing guide pipe of the lower wire threading straightening workbench is in a closed state, the steel wire penetrates into the opening and closing guide pipe, the opening and closing guide pipe plays a role in threading guide), when the wire feeding length reaches the set wire feeding length, the hydraulic shearing action cuts off the steel wire, then the opening and closing guide pipe is opened, and the rotary clamping mechanical claw is used for screwing after pulling the two ends of the steel wire to the set height, so that bundling of the steel bar bundle is realized.

The Chinese patent with the publication number of CN105775201B discloses a steel bar bundling machine based on a driven opening and closing clamp splice device, wherein the driven opening and closing clamp splice device is used for replacing an opening and closing guide pipe in the publication number of CN104925293B, and compared with the opening and closing guide pipe in the publication number of CN104925293B, the driven opening and closing clamp splice device has a simple structure, does not need an active power driving part such as a hydraulic cylinder or an air cylinder, and the like, thereby simplifying a movement mechanism, saving cost, saving a control program of the active power driving part such as the hydraulic cylinder or the air cylinder, and effectively avoiding faults.

Although these bundling machines not only solve the above-mentioned problems, but also obtain market favor, in practical use, the above-mentioned steel bar bundling machine can only realize threading, bundling and rotation of one bundled steel bar, that is, can only use one steel bar to bundle (can only use one steel bar to bundle at a time for a certain fixed position to be bundled) for the steel bar to be bundled, and cannot realize bundling of multiple steel bars (that is, cannot use multiple steel bars to bundle for a certain fixed position to be bundled). Although the bundling effect of the bundling machine is good, the requirement of customers can be met by bundling one steel bar, under certain conditions, the transportation and use requirements can be met by bundling two steel bars at the same time, the application of the steel bar bundling machine is severely limited, and the bundling machine cannot be widely popularized and used; in addition, the wire feeding mode of front and back jacking needs to accurately control the wire feeding process of the steel bar for bundling, and wire feeding is easy to be unsmooth or wrong.

Detailed Description

The technical scheme of the utility model is further described by specific examples.

The following description will take an example of an improved "top-entry bar binder" of the relevant partner company. As shown in fig. 1, a rebar tying machine is shown in detail in the utility model patent "a rebar tying machine with a top inlet wire" (patent No. ZL2021206564094, application date is 2021, 3, 31, and grant notice date is 2022, 2, 1), wherein the screwing manipulator adopts the structure of the utility model patent "a manipulator for screwing and tying" (patent No. ZL2015103514162, application date is 2015, 6, 23, and grant notice date is 2017, 12, 26), and the opening and closing duct adopts the structure of the utility model patent "a driven opening and closing clamp device for wire threading guide applied to a rebar tying machine" (patent No. ZL2016203827699, application date is 2016, 11, 23, i.e. opening and closing duct based on a spring) or the utility model patent "an automatic opening and closing duct device based on a spring piece" (patent No. ZL2020217655389, application date is 2020, 21, and grant date is 2024, 6, i.e. opening and closing duct based on a spring piece ". The opening and closing guide pipes of any structure are adopted, a plurality of opening and closing guide pipes are required to be arranged in the wire feeding direction (namely, the direction from the hydraulic shear to the left clamping working surface of the left rotating arm) so as to form a basically coherent wire feeding channel, and the steel bars for bundling enter the wire feeding channel which is horizontally arranged after being straightened from the rear end of the bundling machine until reaching through holes of the left and right clamping working surfaces of the left and right rotating arms. For convenience of description, the whole wire feeding channel is divided into two components, and the section of the screwing manipulator to the hydraulic shears is called an 'outer wire feeding channel', and the section between the left rotating arm and the right rotating arm of the screwing manipulator is called an 'inner wire feeding channel'.

As shown in fig. 2, the basic operation of the baler is illustrated with respect to bar tying. The cross section of the steel bars is round or approximately round, the steel bars to be bundled conveyed from the steel bar production line are gathered into a bundle, the bundled cross section is round or approximately round, the steel bars for bundling pass through the lower part of the bundle of steel bars, and the left end and the right end of the steel bars for bundling are respectively arranged in the through holes of the left clamping working face positioned below the left rotating arm and the through holes of the right clamping working face positioned below the right rotating arm. In the bundling process, the left rotating arm and the right rotating arm move upwards to drive the bundling reinforcing steel bars to move along the left end and the right end of the reinforcing steel bars to be bundled; because the steel bars to be bundled are gathered into a bundle, the bundled cross section is round or approximately round, the bundled steel bars have small resistance to the steel bars to be bundled, and the bundled steel bars can be well contacted (tightly attached) with the bundle of steel bars formed by gathering (namely, the steel bars to be bundled), in particular, benign contact (tightly attached) with the bottom surface or the lower surface of the bundle of steel bars. At this time, the left clamping working face and the right clamping working face are driven by the left clamping arm and the right clamping arm to be matched to clamp the steel bars for bundling and rotate the steel bars for bundling into knots, and bundles and tie the steel bars formed by gathering together. In a wire feeding channel formed by the open-close guide pipes, front and rear steel bars for bundling adopt a wire feeding mode of jacking front and rear, namely, after hydraulic shearing is carried out, the tail of the front steel bar is jacked forward by the head of the rear steel bar, and moves along the wire feeding channel, so that for the steel bars to be bundled, bundling is realized by only one steel bar for bundling at the fixed position to be bundled, and bundling of a plurality of steel bars cannot be realized.

In the technical scheme developed before the company, the external wire feeding channel is integrally replaced, namely, a developed wire feeding mechanism is adopted as the external wire feeding channel for installation and use, and the detail of the wire feeding mechanism and a steel bar bundling machine using the same is disclosed in the patent of the invention in China (application number 2022116757158, application day 2022, 12 and 26). As shown in fig. 3, the two open-close conduits form an "inner wire feeding channel", and a jack-up mechanism (not shown) is optionally disposed between the two open-close conduits, and a first fixing member and a second fixing member of the wire feeding mechanism are disposed between the inner wire feeding channel and the hydraulic shears, and the first fixing member and the second fixing member are both selected to be disposed in parallel along the wire feeding direction of the reinforcing steel bars for bundling. The first moving part is arranged on the first fixing part and can move along the wire feeding direction of the binding reinforcing steel bars, the first fixing part is selected as a track screw, the first moving part is a sliding block moving on the track screw, and the first moving part is controlled by using a servo motor or a hydraulic motor as a power source. The second fixing part is provided with a wire feeding groove which is used for being matched with a wire feeding channel (namely, a wire feeding channel of the opening and closing guide pipe) and the hydraulic shears in the steel bar bundling machine, so that the steel bar for bundling can be fed along a path (corresponding to a wire feeding direction) of the hydraulic shears-the wire feeding groove-the opening and closing guide pipe. And one end (i.e. the top) of the second moving part is connected with the first moving part, and the other end (i.e. the bottom) of the second moving part is arranged in the wire feeding groove of the second fixed part. When the first moving part moves on the first fixed part (such as a track screw rod), the first moving part drives the second moving part connected with the first moving part to move along the wire feeding direction, and the other end of the second moving part positioned in the wire feeding groove of the second fixed part moves along the wire feeding direction, so that one or two binding steel bars positioned in the wire feeding groove are pushed to the opening and closing guide pipe and the wire feeding channel of the opening and closing guide pipe. As shown in fig. 4, when the section of the second fixing member is observed along the wire feeding direction, it can be seen that the wire feeding groove is disposed at the central position of the second fixing member, the top of the second moving member is fixedly connected with the first moving member, and the bottom of the second moving member is disposed in the wire feeding groove of the second fixing member for pushing the binding bars, at this time, two binding bars are disposed in the wire feeding groove, so as to implement a binding action of providing two binding bars for a certain specific binding position to implement a subsequent clamping rotation. The steel bar bundling machine uses a wire feeding mechanism formed by the cooperation of the wire feeding groove and the moving part to replace an outer wire feeding channel, and a jacking mechanism is arranged in an inner wire feeding channel so as to meet the bundling operation of bars and/or sectional materials. The steel bar bundling machine reserves the basic configuration and/or the components of the prior steel bar bundling machine, and in the design, according to the condition that the wire feeding requirement is one or more steel bars for bundling, the inner wire feeding channel formed by the opening and closing guide pipes expands the diameter in the diameter direction on the applicable condition of the original single steel bar for bundling so as to meet the use requirement of double wires or multiple wires. However, through field test, the wire feeding problem (namely, the conveying problem of the binding steel bar) still exists, for example, (1) after the hydraulic shearing treatment, the binding steel bar can tilt in the wire feeding groove under the condition of not being too straight, so that the front end of the binding steel bar cannot enter the rotary clamping mechanical claw and/or the inner wire feeding channel, and the rear end of the binding steel bar is easy to insert into a wire feeding through hole matched with the hydraulic shearing during wire pushing; (2) When the inner wire feeding channel is formed by the open-close guide pipes, one or two wires are easily clamped by the clamping jaws of the open-close guide pipes during lifting, and lifting and rotating clamping cannot be performed.

In order to solve the above problems, in the technical solution of the present utility model, an inner wire feeding channel and an outer wire feeding channel are formed by using a openable wire feeding mechanism, namely, the openable wire feeding mechanism comprises a first fixing part and a second fixing part which are arranged between the inner wire feeding channel and a hydraulic shear of a steel bar bundling machine, and a third fixing part which is arranged between a left rotating arm and a right rotating arm (namely, between left clamping working surface and right clamping working surface) of a screwing manipulator of the steel bar bundling machine, wherein:

as described with reference to fig. 3, 5 and 6, the first fixing member, the second fixing member and the third fixing member are all disposed in parallel along the wire feeding direction of the reinforcing bars for bundling; wire feeding grooves are provided in the second fixing member and the third fixing member, and in the wire feeding direction, the wire feeding grooves of the second fixing member and the wire feeding grooves of the third fixing member are opposed to form a continuous wire feeding path, in which case the two-part opening and closing duct 19 in fig. 3 is replaced with two third fixing members 30 in fig. 7 (i.e., an inner wire feeding path is constituted by the two third fixing members), and preferably a jack-up mechanism 31 is provided in the middle of the two third fixing members 30. And a cover plate capable of controlling movement is arranged above the wire feeding grooves of the second fixing part and the third fixing part (namely, the tops of the second fixing part and the third fixing part) so as to realize the opening and closing control of the wire feeding grooves (namely, the opening or closing control of the tops of the wire feeding grooves). In order to realize the mobile control of the cover plate, taking the second fixed part as an example, the cover plate is connected with a cover plate control system, the cover plate control system consists of a cover plate control cylinder and a moving mechanism, a cylinder output shaft of the cover plate control cylinder is connected with a supporting transmission part of the moving mechanism, the top of the supporting transmission part is provided with the cover plate, the bottom of the supporting transmission part is provided with the moving part, and the moving part is arranged on a track (such as a slide rail and a slide block matched with the slide rail). The cylinder drives the cylinder output shaft to move according to the instruction, and at the moment, the cylinder output shaft drives the supporting transmission part and the moving part to move left and right on the track, and the top of the supporting transmission part is connected with the cover plate, so that the design of the supporting transmission part is carried out according to the height of the second fixing part, the depth of the wire feeding groove, the height of the track and the moving part and other parameters, and the cover plate is closed and opened and closed to the wire feeding groove. The second fixing member and the third fixing member have substantially the same overall structure, and the length of the third fixing member is smaller than the length of the second fixing member in the wire feeding direction, and generally, the number of the second fixing members is one, and the number of the third fixing members is at least one, preferably 2 to 4.

As described with reference to fig. 3 and 8 to 11, a first moving member that moves in the wire feeding direction of the reinforcing bars for bundling is provided on the first fixing member, the top of the second moving member is connected to the first moving member, and the bottom of the second moving member is provided in the wire feeding groove of the second fixing member; when the first moving part moves on the first fixed part, the first moving part drives the second moving part connected with the first moving part to move along the wire feeding direction, and the bottom of the second moving part in the wire feeding groove of the second fixed part moves along the wire feeding direction, so that one or more binding steel bars in the wire feeding groove are pushed to a wire feeding channel in the steel bar binding machine, namely, the wire feeding groove of the third fixed part is arranged between the left rotating arm and the right rotating arm of the screwing manipulator of the steel bar binding machine.

As shown in fig. 8 to 11, in the wire feeding mechanism of the present utility model, fig. 8 is a view (second moving member body) viewed along a wire feeding direction, fig. 9 is a plan view (second moving member body) corresponding thereto, and fig. 10 and 11 are side views (partial cross-sectional views) of a state in which a wire feeding through hole is closed and opened, respectively, and are described below in combination:

From the construction shown in fig. 8 and 9, the second moving member includes a lateral portion 26-1, a vertical portion 26-2, and a protruding portion 26-3, the lateral portion constituting the top (or so-called tip) of the second moving member. One end of the transverse part is fixedly connected with the first moving part so as to enable the second moving part and the first moving part to be connected into a whole, and a first connecting hole 26-4 is arranged at one end of the transverse part, and the two parts are fixedly connected through a screw or a bolt; the transverse part has a certain length, one end of the transverse part is fixedly connected with the first movable part, and the other end of the transverse part extends to the upper part of the wire feeding groove of the second fixed part; the vertical part is arranged in the vertical downward direction which is basically vertical to the transverse part, and the bottom of the vertical part is provided with the protruding part. The protruding part forms the bottom (or called bottom end) of the second moving part, and the shape of the vertical part and/or the protruding part is matched with the shape of the wire feeding groove of the second fixed part. When the first moving part moves on the first fixed part, the first moving part drives the second moving part to integrally move, and at the moment, the vertical part and/or the protruding part can move in the wire feeding groove of the second fixed part and push the bundling steel bars positioned in the wire feeding groove to move in the wire feeding channel.

In the actual operation process, the steel bars for bundling are straightened and sheared by the straightener, the whole and/or the tail parts of the steel bars are not flat and/or tilted, and defects that wire feeding is impossible or wire feeding defects are easily generated when the second moving part is used for pushing, for example, the tilted tail parts of the steel bars for bundling are wrongly fed into the wire feeding through holes, the steel bars for bundling, which are not flat in whole, extend out of the wire feeding groove in the vertical direction and then cannot enter the wire feeding groove (namely the inner wire feeding channel) of the subsequent right rotating arm (right clamping working surface) and/or the third fixing part. This requires a second moving member that mainly functions as a wire feeding member, and can ensure that the head of the reinforcing bar for bundling smoothly enters the inner wire feeding passage and the tail thereof does not enter the wire feeding through hole when the wire is fed. In the structure of the second moving part, a sliding groove 26-8 is arranged on a transverse part connected with a vertical part, a second connecting hole is arranged on the transverse part around the sliding groove, the vertical part of the baffle plate is basically connected with the horizontal part of the baffle plate at a ninety-degree angle, if the vertical part of the baffle plate and the second connecting hole are fixed or connected into a whole, the vertical part of the baffle plate is connected with the second connecting hole through a screw or a bolt, an inserting sheet 26-10 is arranged in the sliding groove, and the inserting sheet is connected with an inserting sheet control system so as to control the movement of the inserting sheet in the vertical direction through the inserting sheet control system, and further the opening and closing state of a wire feeding through hole is controlled at the bottom end of the inserting sheet.

The tab control cylinder as a tab control system is selectively provided on the hydraulic shears or on a lateral portion of the second moving member. In order to prevent the insert from being separated from the slide groove, a slide hole 26-7 (the slide hole is arranged along the vertical direction) is arranged in the slide groove, and the slide block of the insert is arranged in the slide hole, so that when the insert moves along the vertical direction, the slide block of the insert moves along the vertical direction in the slide hole and simultaneously limits the movement range of the insert. It should be noted that, the upper surface of spout and the upper surface parallel and level of vertical portion, protruding portion, like this, the inserted sheet can realize carrying out vertical orientation's upper and lower removal at the surface of "spout-vertical portion-protruding portion" to avoid the hindrance of vertical orientation. In the vertical direction, the distance from the horizontal part of the baffle to the bottom end of the second movable part is basically consistent with the depth of the wire feeding groove of the second fixed part. When wire feeding is performed, the cover plate of the second fixing part is opened, the second moving part moves along the wire feeding direction, at the moment, the bottom end of the second moving part is positioned in the wire feeding groove, the horizontal part of the baffle plate is equivalent to the function of part of the cover plate, and the wire feeding defect is reduced.

The design scheme of matching the wire feeding groove with the cover plate is adopted, and the opening and closing states of the wire feeding groove are controlled through the cover plate control system. When the steel bar for bundling advances the silk from the hydraulic pressure department to second fixed part (the wire feeding groove of second fixed part), the apron of second fixed part is closed state to make the wire feeding groove of second fixed part wholly appear capping and seal, guarantee that the steel bar for bundling can only move in the passageway that wire feeding groove and apron constitute. When the second fixing part feeds the wire to the third fixing part, the cover plate of the second fixing part is in an open state, so that the whole wire feeding groove of the second fixing part is in a non-cover sealing state, at the moment, the baffle plate of the second moving part covers the upper part of the wire feeding groove, namely, the horizontal part of the baffle plate is just above the wire feeding groove (namely, the position of the original cover plate is clung to the opening of the wire feeding groove), the capping effect of the original cover plate is achieved in the wire feeding direction (namely, in a certain area in front of the second moving part), the wire feeding from the outer wire feeding channel to the inner wire feeding channel is realized, and the problem that the bundling steel bar can only move in the channel formed by the wire feeding groove and the baffle plate and is avoided because the baffle plate is upwarp or is uneven as a whole is solved.

The design scheme of the sliding chute and the inserting piece is adopted, and the opening and closing state of the wire feeding through hole is controlled through the inserting piece control system. When the steel bar for bundling enters the second fixing part (the wire feeding groove of the second fixing part) from the hydraulic shear, the inserting piece is in a lifting state, the wire feeding through hole is in an open state (figure 11), and the steel bar for bundling enters the second fixing part (the wire feeding groove of the second fixing part). After the wire feeding is completed, the inserting piece is in a falling state, the wire feeding through hole is in a closed state (figure 10), the wire feeding is ready, and the subsequent steel bars for bundling cannot enter the second fixing part. When wire feeding is performed, since the wire feeding through holes are always in a closed state, the problem caused by upward tilting of the tail part of the wire feeding groove can be avoided no matter whether one wire or a plurality of wire feeding through holes are tilted or not.

For the third fixing part, the design scheme of matching the wire feeding groove with the cover plate is adopted, and the opening and closing states of the wire feeding groove are controlled through the cover plate control system. In the wire feeding process, the cover plate of the third fixing part is in a closed state, so that the wire feeding groove of the third fixing part is integrally closed by a cover, the steel bar for bundling at the second fixing part can only move in a channel (namely an inner wire feeding channel) formed by the wire feeding groove of the third fixing part and the cover plate, and the problem caused by the fact that the steel bar for bundling is upturned or is not very flat is avoided; when the wire lifting and bundling are carried out, the cover plate of the third fixing part is in an open state, so that the wire feeding groove of the third fixing part is integrally closed without a cover, at the moment, the left rotating arm and the right rotating arm of the screwing manipulator move upwards, and further the steel bars for bundling are driven to integrally come out of the wire feeding groove of the third fixing part. For the inner wire feeding channel based on the opening and closing guide tube (whether the opening and closing guide tube is based on a spring or the opening and closing guide tube is based on an elastic sheet) in the prior art, when the left rotating arm and the right rotating arm of the screwing manipulator move upwards to lift the steel bar for bundling, the resistance of the claw needs to be overcome (the resistance is from the spring or the elastic sheet), and the resistance is just the power for the claw to restore the original position (to restore the inner wire feeding channel), for one steel bar for bundling, when the resistance of the claw is overcome and the steel bar for bundling is separated from the inner wire feeding channel, the situation of wire clamping (namely the steel bar for bundling is clamped by the claw and cannot be completely separated from the inner wire feeding channel) can exist, so that the wire feeding defect is caused. When the left and right rotating arms of the screwing manipulator move upwards to lift two or more steel bars for bundling, the probability of the situation of wire clamping is increased in geometric multiple, and even continuous use is impossible. Through the design scheme of wire feeding groove and apron, when screwing the left and right swinging arms upward movement of manipulator in order to promote bundling and use the reinforcing bar, wire feeding groove presents uncovered open condition, no matter two or many bundling are promoted with the reinforcing bar, can not produce any resistance, only need after promoting, control the apron again through apron control system and seal wire feeding groove can to solve "card silk" problem, realize continuous production and use.

The wire feeding mechanism is used for replacing the original 'outer wire feeding channel' and 'inner wire feeding channel', the through holes of the left clamping working surface and the right clamping working surface are widened according to the requirement, and meanwhile, the conveying requirement of one or more steel bars for bundling is met. The whole steel bar bundling machine adopts a wire feeding groove of a second fixing part as a main body of an outer wire feeding channel, adopts a wire feeding groove of a third fixing part as a main body of an inner wire feeding channel, and adopts a second moving part to push bundling steel bars to realize wire feeding aiming at a manipulator and the inner wire feeding channel, so that wire feeding can be carried out one by one, wire feeding can also be carried out by a plurality of (such as two) steel bars, and bundling of one steel bar or bundling of a plurality of steel bars aiming at a bundling position can be realized; after wire feeding is achieved, the first moving part drives the second moving part to return to an original position close to the hydraulic shear, and after the steel bars to be bundled are processed by the hydraulic shear and fall into the wire feeding groove, subsequent wire feeding is performed. In the whole wire feeding process, the defects of wire feeding of the prior open wire feeding channel and the open-close catheter are avoided by controlling the opening and closing states of the inner wire feeding channel and the outer wire feeding channel. For the whole steel bar bundling machine, original wire feeding modes (such as cutting the tail of the head top previous steel bar of the next steel bar) are reserved before the steel bar for bundling is cut at the hydraulic pressure and falls into the wire feeding groove, the original wire feeding modes are abandoned after the steel bar for bundling falls into the wire feeding groove, pushing type wire feeding is adopted, wire feeding efficiency is improved under the condition of guaranteeing wire feeding safety, and the design not only provides convenience for new customers, but also gives attention to the use habit of old customers.

In order to solve the bundling problem of stacking of the section bars or the steel pipes, a jacking mechanism is arranged among a plurality of third fixing parts (preferably arranged at the central position between two third fixing parts) of an inner wire feeding channel, and concretely, the utility model is disclosed in China patent application of jacking mechanism and a steel bar bundling machine using the jacking mechanism (the application date is 2022, 12 and 17, the application number is 2022233889558), or the utility model is disclosed in patent application of jacking mechanism and a steel bar bundling machine using the jacking mechanism (the application date is 2022, 12 and 17, the application number is 202211627837X), or the jacking mechanism comprises a jacking cylinder, the whole jacking mechanism is arranged on a mounting base of the third fixing part of the bundling machine by using a mounting bracket, the jacking cylinder is fixedly arranged below a lower mounting plate, an output shaft of the jacking cylinder penetrates through the lower mounting plate and is connected with the bottom end of a jacking core, a support column is arranged around the lower mounting plate, the top end of the support column is provided with an upper mounting plate, and an observation and detection hole is arranged on the support column; the jacking core body passes through the upper mounting plate and the mounting base, and the top end of the jacking core body is positioned between the inlet and the outlet of the wire feeding groove of the adjacent third fixing part; the limiting device is sleeved on the jacking core and is attached to the jacking core (namely, under the condition that the blocking is not caused by the up-and-down movement of the jacking core, the distance between the limiting device and the jacking core is reduced as much as possible, the jacking core is prevented from shaking all around, the jacking cylinder and the output shaft of the jacking cylinder are very easy to block due to shaking), and the upper mounting plate is fixed on the lower surface of the mounting base and the limiting device is fixed on the upper surface of the mounting base through screws or bolts. The detection device is arranged at one side of the observation and detection hole according to the requirement so as to detect the movement amount of the jacking core body in the vertical direction and transmit a detection signal back to the controller of the bundling machine so as to be adjusted or controlled; similarly, in the design scheme of the wire feeding groove and the cover plate, and the design scheme of the sliding groove and the inserting piece, a detection device can be arranged to detect the movement quantity of the cover plate and the inserting piece, and the detection signal is transmitted back to the controller of the bundling machine so as to be adjusted or controlled.

In practical use, the length of the binding steel bars positioned outside the left clamping working surface and the right clamping working surface is basically consistent, and the binding effect of the clamping rotation of the screwing manipulator is relatively good. Although the length of the binding steel bars obtained through the straightening machine and the hydraulic shearing treatment is basically consistent according to the preset program control of the binding machine and can meet the requirement of the binding length, when two or more binding steel bars are adopted for wire feeding and/or wire pushing, the binding steel bars after the hydraulic shearing treatment enter an outer wire feeding channel in sequence, and at the moment, the former wire protrudes relatively to be closer to the inner wire feeding channel in the wire feeding direction due to the friction effect among the wires; when the second moving part is used for pushing wires, the second moving part pushes against the rear wires (namely, the bundling reinforcing steel bars entering the outer wire feeding channel at the moment, the wires interact in the wire feeding groove to generate friction force, the wires are in the same channel, the rear wires move forwards in the process of moving forwards, the situation that the wires which are originally static in the channel slide forwards along the front is generated due to crowding, the length of the bundling reinforcing steel bars positioned at the outer sides of the left and right clamping working surfaces is inconsistent, and the bundling effect is poor. Referring to fig. 1 and 7, the damping mechanism is not shown in fig. 1, the screwing manipulator is not shown in fig. 7, fig. 7 is a top view of fig. 1, wherein the projection of the screwing manipulator is omitted, the third fixing component is used to replace the opening and closing duct, after being used as the inner wire feeding channel, the damping mechanism is arranged on the outer side of the left clamping working surface (i.e. the outer side of the screwing manipulator), and comprises two opposite partition plates, and a magnet arranged on the outer side of each partition plate, an extending wire feeding channel is formed between the partition plates, and the extending wire feeding channel is used as a through hole of the screwing manipulator and a horizontal extension of the inner wire feeding channel (i.e. the extending wire feeding channel and the through hole of the screwing manipulator and the inner wire feeding channel are basically located on a horizontal plane). Taking double wire feeding (two binding steel bars) as an example, the two binding steel bars subjected to hydraulic shearing treatment sequentially enter an outer wire feeding channel, and at the moment, the former wire (namely the binding steel bar which firstly enters the outer wire feeding channel) relatively protrudes in the wire feeding direction due to friction action between the two wires and is closer to the inner wire feeding channel; when the second moving part is used for pushing wires, the second moving part pushes against the next wire (namely, the bundling reinforcing steel bar which enters the outer wire feeding channel later), at the moment, the two wires interact in the wire feeding groove to generate friction force, and the situation that the next wire slides forwards in the inner wire feeding channel and the outer wire feeding channel along with the previous wire is generated because the two wires are mutually crowded. After the previous wire enters the extended wire feeding channel formed between the partition boards, the previous wire is adsorbed by the magnet and then leans against the surface of the partition boards due to the action of the magnet. At the moment, larger friction resistance is generated between the wire and the partition plate and is larger than friction between the two wires, the second moving part pushes the tail part of the other wire in the wire feeding groove, at the moment, the wire is not adsorbed by the magnet, and further the wire feeding resistance is smaller than the resistance of the former wire, so that the tail parts of the two wires are level, at the moment, the heads of the two wires are basically level, enter the extending wire feeding channel and are acted by the magnet, and the resistances of the two wires are basically consistent; and then the second moving part pushes the tail parts of the two wires together to feed the wires. By adopting the wire feeding and/or wire pushing mode, when double wires or multiple wires are fed, the head and the tail of each wire can be basically flush, the lengths of the binding reinforcing bars positioned at the outer sides of the left clamping working surface and the right clamping working surface are basically consistent, and a better binding effect is realized; the damping mechanism is simple and compact in structure and can be adapted to a narrow space of a production site to the greatest extent.

The foregoing has described exemplary embodiments of the utility model, it being understood that any simple variations, modifications, or other equivalent arrangements which would not unduly obscure the utility model may be made by those skilled in the art without departing from the spirit of the utility model.
