Detailed Description
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.
Example 1:
referring to fig. 1 and fig. 2, the present embodiment provides a radial plastic pipe clamping mechanism, a supporting platform 601, a pair of symmetrically distributed clamping units disposed on the supporting platform 601 for clamping the plastic pipe 100 from two radial sides of the plastic pipe 100, and a pair of clamping driving assemblies respectively connected to the pair of clamping units for respectively driving the pair of clamping units to move toward and away from each other. A receiving section 613 for receiving the plastic pipe 100 is formed between the pair of clamping units.
Specifically, each of the pair of clamping units comprises a supporting frame 603 connected with the clamping driving assembly, and at least one clamping plate 605 distributed on one side end surface of the supporting frame 603; the clamping plates 605 on the pair of clamping units, respectively, are facing the plastic tubing 100.
Taking an optional case as an example, the clamping unit of the present embodiment includes a clamping plate 605 distributed on the same side end surface of the supporting frame 603; and the end face of the clamping plate 605 facing the plastic tube 100 is provided with a resilient cushion 608. The elastic cushion 608 is a pad made of, for example, but not limited to, silicone. The elastic buffer pads 608 are fixed to the clamping plate 605 by means of, for example, but not limited to, high-strength adhesive or welding, where the clamping plate 605 is made of, for example, but not limited to, plastic material or metal material.
Specifically, the clamping driving assembly adopted in the present embodiment includes at least one sliding rail 609 arranged on the supporting platform 601, and a driving cylinder 612 connected to the supporting frame 603 through a "Chinese" connecting frame 610; the supporting frame 603 is slidably connected to at least one sliding rail 609, for example, two sliding rails 609 are provided, that is, two sliding grooves adapted to the two sliding rails 609 are correspondingly provided on the bottom end surface of the supporting frame 603; the end of the piston rod of the driving cylinder 612 is connected to the "knitting" shaped link frame 610. The 'knitting convenience' shaped connecting frame 610 is mainly used for improving the stability and balance of the supporting frame 603 sliding along the sliding rail 609 compared with the fact that a single point of the piston rod of the driving cylinder 612 is connected with the supporting frame 603 under the action of the piston rod of the driving cylinder 612.
The extension and retraction of the piston rod of the driving cylinder 612 relative to the body of the driving cylinder 612 can realize the movement of the support bracket 603 on the support platform 601, and the movement can realize the movement of the pair of clamping units towards or away from each other. The drive cylinder 612 is not limited to a certain product type, that is, the drive cylinder 612 extending and retracting through the piston rod can meet the use requirement of the present embodiment. The driving cylinder 612 can be directly and fixedly connected to the supporting platform 601, and the problem of arrangement of the driving cylinder 612 can be realized through other intermediate connecting components. It should be noted that the adjustment of the distance between the pair of clamping units by the driving cylinder 612 designed in this embodiment is mainly used to adjust the distance between the pair of clamping units in the clamping state so as to adapt to plastic pipes 100 with different dimensions, thereby playing a role in radial clamping and limiting of plastic pipes 100 with different pipe diameters.
Example 2:
referring to fig. 3 to 8, on the basis of the radial clamping mechanism for plastic pipes in embodiment 1, the present embodiment provides a tractor, which includes: the machine frame 500, and a plastic pipe traction conveying mechanism and a plastic pipe radial clamping mechanism as in embodiment 1 which are sequentially arranged on the machine frame 500 along the conveying direction F of the plastic pipe 100.
In detail, the frame 500 of the tractor of the embodiment has a hollow conveying cavity penetrating along the plastic pipe conveying direction F, and both ends of the hollow conveying cavity in the width direction F are openings suitable for the plastic pipe to enter and exit, and the openings are communicated with the hollow conveying cavity.
The plastic pipe traction transmission mechanism comprises an upper transmission wheel assembly and a lower transmission wheel assembly which are arranged in the hollow transmission cavity; a transmission section 8 for passing through the plastic pipe is formed between the upper transmission wheel assembly and the lower transmission wheel assembly. The supporting platform is disposed on the rack 100 and located beside the hollow conveying cavity, where for "beside", it is to be noted that, along the moving direction F of the plastic pipe 100, the supporting platform is located in front of the hollow conveying cavity, that is, during the conveying and moving process of the plastic pipe 100, the supporting platform first passes through the hollow conveying cavity and then reaches the supporting platform.
Specifically, the lower transmission wheel assembly comprises a plurality of lower transmission rotating wheels 201 which are arranged horizontally at intervals along the transmission direction F of the plastic pipe; the upper conveying wheel assembly comprises a plurality of upper conveying wheels 301 which are arranged above the plurality of lower conveying wheels 201, are spaced along the conveying direction F of the plastic pipes and are horizontally arranged.
Referring to fig. 7, the upper transmission runner 301 and the lower transmission runner 201 adopted in the present embodiment each include a cylindrical supporting portion 101, and frustum-shaped limiting portions 103 symmetrically disposed at two ends of the supporting portion 101; wherein a concave arc-shaped structure 107 is formed between the side end of the limiting part 103 close to the supporting part 101 and the supporting part 101.
In more detail, the plurality of upper transport wheels 301 are the same size; the plurality of lower transport wheels 201 are the same size; and the upper transport rotor 301 is the same size as the lower transport rotor 201. The outer diameter of the stopper 103 gradually increases from the proximal support 101 toward the distal support 101 in the direction F.
It should be noted here that the outer diameter of the frustum-shaped structure specifically corresponding to the frustum-shaped structure of the limiting portion 103 is gradually increased from the near support portion 101 to the direction F of the far support portion 101, so that the outer diameters of the plastic pipes adapted to the upper transmission runner 301 and the lower transmission runner 201 of the present embodiment are not unique, that is, the application range of the upper transmission runner 301 and the lower transmission runner 201 to the plastic pipes is improved. By combining the structure with the adjusting structure for adjusting the longitudinal height between the upper transmission wheel assembly and the lower transmission wheel assembly, the range of the plastic pipes which are transmitted and suitable for the integral plastic pipe traction transmission mechanism can be larger.
The above-mentioned adjusting structure for adjusting the longitudinal height between the upper transmission rotating wheel assembly and the lower transmission rotating wheel assembly can adopt, for example and without limitation, a traction cylinder and a guide rail structure cooperatively used in a pipe double-tractor in the PVC pipe production line disclosed in publication number CN103213267A, that is, for example, the upper transmission rotating wheel assembly of the upper transmission rotating wheel assembly and the lower transmission rotating wheel assembly in this embodiment is fixed on a support frame adapted to move up and down relative to the lower transmission rotating wheel assembly, and the support frame herein is lifted and lowered relative to the fixing base 401 for fixing the lower transmission assembly by the traction cylinder and the guide rail structure, so that the longitudinal height between the upper transmission rotating wheel assembly and the lower transmission rotating wheel assembly can be adjusted, that is, the size of a channel formed by the upper transmission rotating wheel assembly and the lower transmission rotating wheel assembly and adapted to the circulation of plastic pipes is adjusted. The detailed structure of this embodiment is not described again here.
In addition, the present implementation also designs a structure in which the upper transmission rotor 301 and the lower transmission rotor 201 are arranged in a staggered manner, that is, each lower transmission rotor 201 is located in a space formed by every two adjacent lower transmission rotors 201. Under the condition, the pipe walls of the upper transmission rotating wheel 301 and the lower transmission rotating wheel 201, which are in contact with the plastic pipe, are non-concentric parts, so that in the direction F of axial movement of the plastic pipe, the upper transmission rotating wheel 301 and the lower transmission rotating wheel 201 are combined and then compared with the structure of the upper transmission rotating wheel 301 and the lower transmission rotating wheel 201 which are opposite up and down, the structure of staggered arrangement in the embodiment can improve the contact force application range of the plastic pipe in the axial direction, and improve the driving efficiency of the transmission rotating wheels on the axial movement of the plastic pipe 100.
In order to reduce the abrasion of the upper transmission rotating wheel 301 and the lower transmission rotating wheel 201 to the outer wall surface of the plastic pipe in the process of contacting and transferring the plastic pipe, in a preferred implementation condition, the upper transmission rotating wheel 301 and the lower transmission rotating wheel 201 are both made of high polymer plastic materials.
The lower transmission rotating wheels 201 are fixedly connected with lower rotating shafts 202 which are suitable for driving the lower transmission rotating wheels 201 to rotate respectively; and a lower rotating gear 203 is fixedly connected to the lower rotating shaft 202 corresponding to each of the plurality of lower transmission rotating wheels 201. Here, the portions of the lower rotating shaft 202 located at both sides of the lower transferring wheel 201 are connected to the frame 500 through bearings so that the lower rotating shaft 202 can rotate with respect to the frame 500.
Referring to fig. 8, the driving force for the axial movement of the plastic pipe is realized by connecting the lower transmission gears 203 fixedly connected to the lower shafts 202 of each two adjacent lower transmission wheels 201 through a lower transmission gear 205, so that each two adjacent lower transmission wheels 201 have the same rotation direction F. The lower shaft 202 of at least one lower transmission wheel 201 of the plurality of lower transmission wheels 201 is connected to a lower driver (not shown) adapted to drive the lower shaft 202 to rotate (the lower driver is located inside the frame 500). The lower driver here is, for example, but not limited to, a reduction motor, and the type of the reduction motor is not limited in any way, and may be a reduction motor that can realize rotation of the lower rotating shaft 202 in principle. At this time, only the lower rotating shaft 202 corresponding to one lower transmission rotating wheel 201 in the plurality of lower transmission rotating wheels 201 may be connected to the two reduction motors, or the lower rotating shafts 202 of two lower transmission rotating wheels 201 therein may be connected to the two reduction motors, and when the lower rotating shafts 202 of two lower transmission rotating wheels 201 are connected to the two reduction motors, the rotating speeds of the two reduction motors need to be adjusted, so that the rotating speeds of the two reduction motors are the same, thereby maintaining the stability and balance of the lower transmission rotating wheel assembly formed by the plurality of lower transmission rotating wheels 201 during the operation process.
In this embodiment, as an optional implementation case, the plurality of upper transmission rotating wheels 301 are respectively fixedly connected to upper rotating shafts 302 adapted to drive the upper transmission rotating wheels 301 to rotate; the upper transmission rotating wheels 301 are respectively and correspondingly connected with upper rotating shafts 302 which are fixedly connected with upper rotating gears; the upper transfer gears fixedly connected to the upper shafts 302 of every two adjacent upper transfer rotors 301 are connected to each other through an upper transfer gear, so that every two adjacent upper transfer rotors 301 have the same rotation direction F. Here, the upper rotating shaft 302 is connected to the frame 500 through a bearing at portions on both sides of the upper transmission rotor 301, so that the upper rotating shaft 302 can rotate with respect to the frame 500. The upper shaft 302 of at least one upper transmission wheel 301 of the plurality of upper transmission wheels 301 is connected to an upper driver (not shown) adapted to drive the upper shaft 302 to rotate, the upper driver being disposed inside the housing 500. The upper driver is, for example, but not limited to, a reduction motor, and the type of the reduction motor is not limited in any way, and the reduction motor is functionally satisfied to rotate the upper rotating shaft 302. For the number of the upper drivers, reference can also be made to the upper drivers, and here, only the operating parameters of the upper drivers and the lower drivers are coordinated to ensure that the rotating speeds of the upper drivers and the lower drivers are the same to maintain the stability and balance of the plastic pipe in the axial moving operation process formed by the lower transmission rotating wheel assembly and the upper transmission rotating wheel assembly. Here, the upper and lower shafts 302 and 202 are rotatably connected to the wall of the hollow conveyance chamber of the gantry 500 through bearings, and the up-down driver, the up-down rotation gear 203, and the up-down transfer gear 205 are disposed inside the gantry 500.
For the plurality of upper transmission wheels 301 in this embodiment, none of them may be connected to the upper driver, where the plurality of lower transmission wheels 201 are respectively connected to the corresponding upper rotating shafts 302, and the upper rotating shafts 302 may rotate relative to the tractor. Under the condition, the driving force for the axial movement of the plastic pipe is generated through the lower transmission rotating wheels 201, the upper transmission rotating wheel 301 only rotates passively in the axial movement of the plastic pipe, at the moment, the upper transmission rotating wheel 301 mainly has the limiting and axial guiding effects on the upper portion of the plastic pipe relative to the lower portion of the plastic pipe where the lower transmission rotating wheel 201 is located in the axial movement of the plastic pipe, and the plastic pipe is prevented from being tilted upwards in the axial movement process under the action of the lower transmission rotating wheel 201.
Example 3:
referring to fig. 9, based on embodiment 2, the present embodiment provides a plastic pipe processing system, including: the device comprises a first tractor 1, a stretching device 2, a cooling device 3 and a second tractor 5 which are arranged in sequence; the first tractor 1 conveys the plastic pipe 100 to the stretching device 2, and the plastic pipe 100 may be simultaneously stretched in the stretching device 2 in the radial direction or the axial direction or the radial direction, so that the first tractor 1 does not need to perform radial limiting clamping on the plastic pipe 100 at this time, and the second tractor 5 is butted with a cutting device to perform segmented cutting on the plastic pipe 100, and therefore, in order to perform radial clamping limiting before cutting on the plastic pipe 100, the second tractor 5 of the embodiment adopts the tractor of the embodiment 2.
In the systematic processing process of the plastic pipe 100, especially before the cutting operation, the operation of the pipe traction transmission mechanism needs to be stopped, that is, the axial movement of the plastic pipe 100 is stopped, and before the cutting operation is performed, the operation of the plastic pipe radial clamping mechanism needs to be started, so that the plastic pipe radial clamping mechanism realizes radial limiting clamping on the plastic pipe 100 to be cut, at this time, the specific on-off control of the traction transmission mechanism and the on-off control of the plastic pipe radial clamping mechanism can be combined with a distance sensor configured by a cutting knife on the cutting device to acquire signals to a controller, and the controller controls the on-off control of the traction transmission mechanism and the on-off of the plastic pipe radial clamping mechanism, and can also be a manual control operation mode, so that absolute limitation is not performed in this embodiment.
For the plastic pipe radial clamping mechanism arranged on the tractor in this embodiment, compared with the case that a clamping device for radially clamping the pipe is arranged between the tractor and the cutting device, the integration of the plastic pipe radial clamping mechanism on the tractor can not only reduce the device processing cost, but also reduce the alignment problem between the clamping device and the tractor which are arranged respectively, and the alignment problem is mainly embodied in that, for the plastic pipe radial clamping mechanism integrated on the tractor in this embodiment, the same parameters can be set and controlled by the driving cylinders respectively corresponding to the pair of clamping units, that is, the pair of clamping units which are arranged are in a mirror symmetry structure relative to the hollow conveying cavity for conveying the plastic pipe 100, so that in the initial state relative to the plastic pipe 100 which passes through the hollow conveying cavity, the distance between the pair of clamping plates and the plastic pipe 100 is the same when the driving cylinder is in a retraction state, and the extending distance of the piston rod of the driving cylinder can be calculated according to the distance between the clamping plates and the outer side wall of the plastic pipe 100, namely the stroke of the piston rod is determined, and for the plastic pipes 100 with different pipe diameters, the extending distance of the piston rod of the driving cylinder corresponding to the pair of clamping units can be adjusted correspondingly. The separate type tractor and the separate type clamping device need to position and calibrate the position of the clamping device relative to the tractor, so that when the plastic pipe 100 is sent into the clamping device through the tractor, the plastic pipe 100 is located in the middle of the pair of clamping units in the initial state, and the distance between two outer side walls of the plastic pipe 100 and different clamping plates is determined.
It should be noted that, for both the stretching device 2 and the cooling device 3 of the present embodiment, a device commonly used in the prior art can be adopted, and the present embodiment is not particularly limited, but it is to be specifically noted that the plastic pipe traction transmission mechanism of the tractor 1 in the present embodiment can be optionally adopted to improve the prevention of the plastic pipe 100 from shifting in the radial direction during the axial conveying process of the plastic pipe 100. In addition, the cooling device 3 also needs to adopt a supporting structure suitable for pulling the plastic pipe in the process of cooling processing after stretching the plastic pipe, and the pipe pulling and conveying mechanism in the embodiment 2 can also be adopted for the supporting structure used for pulling and conveying the plastic pipe in the cooling device 3.
