In conclusion, the continuous mine powder open bag taking machine can realize continuous bag cutting, sealing and conveying of the open bag and preparation for subsequent processes;
therefore, the continuous bag taking machine for the mine powder open bags fills up the blank of automatic production in the processes of separating, clamping, loading and filling the open bags. All steps from the initial rolling of the stock to the filling of a separate open-top bag are achieved. Secondly, with the help of the roller follower, the automatic production of the hemming plate and the sewing mechanism is realized. And thirdly, the roller turnover mechanism changes the position direction of the open bag to realize the vertical direction, so that the bag is convenient to take.
Specifically, the roller and flap mechanism 30 includes a base 31, an upper bag flap 33, and a frame 37; the base 31 is provided with a hinged seat 32; the frame 37 is positioned at one side of the base 31; a press roller 312 and a driving roller 39 are arranged above the frame 37; a first driving motor 38 for driving the driving stick 39 to rotate is arranged on the frame 37;
a gap is formed between the press roller 312 and the driving roller 39; a guide rod 310 is arranged in front of the gap between the compression roller 312 and the driving rod 39;
one end of the upper bag turning plate 33 is hinged with the hinge seat 32, and the other end leans against the frame 37 and is positioned below the driving stick 39 and the guide stick 310;
a sucker 35 is arranged above the upper bag turning plate 33; a baffle is arranged on one side of the upper bag turning plate 33, and a whole bag plate 34 is arranged on the other side;
the back of the upper bag turning plate 33 is provided with a first telescopic device 311; one end of the first telescopic device 311 is hinged with the upper bag turning plate 33, and the other end is hinged with the base 31.
The roller and the plate turnover mechanism 30 are designed to be used in cooperation with the bag feeding mechanism, and as shown in fig. 2 and 3, the main function is to convey the bags to the bag feeding mechanism and supply the bags to the bag feeding mechanism for subsequent actions, including powder bagging, weighing and the like
The bag rolling mechanism can be divided into two parts, namely a roller part and a turning plate part, wherein the roller part mainly feeds the bag roll into the turning plate, and then the turning plate pushes the turning plate upwards through the action of an air cylinder and is erected for the action of a rear mechanism.
The turning plate mechanism comprises an upper bag turning plate 33, a base 31, a hinged seat 32, a first telescopic device 311 and a bag arranging cylinder, wherein the upper bag turning plate 33 is also fixed with two vacuum suckers 35, and the function of the turning plate is to suck the bags when the upper bag cylinder pushes the turning plate to move upwards so as not to enable the bags to fall or fly forwards.
The action process of the whole mechanism is as follows:
after the bag pressing roller 312 and the driving roller 39 roll down, the bag pressing roller moves downwards along the inclination angle of the upper bag turning plate 33 to contact with the lower adjusting angle steel 36, and then the bag arranging cylinder arranged beside the upper bag turning plate 33 starts to act. The cylinder is contracted to push the bag to the left baffle for positioning.
The baffle and lower adjustment angle 36 provide a "U" shaped channel that is mounted on the upper bag flap 33 at a position that is adjustable according to the size of the bag. The reason that the bag arranging cylinder needs to be added for arranging the bags is that the turning plate needs to be clamped by a subsequent bag feeding mechanism after being erected. After the bag is completed, the suction cup 35 starts to act to firmly suck the bag, so that the bag can be attached to the upper bag turning plate 33. At this point, the first telescoping device 311 begins to actuate, extending the first telescoping device 311 outward, pushing the upper bag flap 33 upward until the upper bag flap 33 is substantially perpendicular to the underlying base 31. When the upper bag turning plate 33 is turned up, the opening part of the bag is higher than the turning plate by a certain distance for the subsequent mechanism to clamp. The principle of the roller bag feeding mechanism is the same as that of the prior transmission roller, but because the bags are not conveyed linearly, a group of rollers are added for guiding, so that the bags can be conveyed to the upper bag turning plate 33. When the first telescopic device 311 retracts to the minimum stroke, the angle between the upper bag flap 33 and the base 31 is 60 °, and the angle of the bag output between the driving roller 39 and the guiding roller 310 is 60 °, so that the two parts can be well butted. The roller mechanism is composed of three groups of rollers, wherein a main driving roller 39 is connected with a first driving motor 38 through a coupler to drive other two groups of rollers to rotate along with the driving rollers, so that the bags on the workbench are rolled in and are conveyed to the turning plate.
The bag transfer and cutting mechanism is shown in fig. 5, and can be divided into two parts, namely a front roll bag transfer device 60 and a bag cutting mechanism 50, and a rear horizontal support rod and roller driving device 70.

a second pressing roller 53 is arranged below the cross beam; a bag conveying roller 52 is arranged below the second pressing roller 53; the sliding plate 54 is driven to move up and down by a second telescopic device 58; the mounting frame 51 is provided with a second driving motor 59 for driving the bag conveying roller 52 to rotate.
The rolled bag conveying device 60 comprises a conveying rack 61; a first transition roller 62 is arranged on the conveying frame 61; an input frame is arranged above one end of the conveying rack 61; the bag conveying roller 52 is positioned at the other end of the conveying frame 61; a second transition roller 64 and a third transition roller 65 are arranged on the input frame; an inclined surface 63 is arranged between the first transition roller 62 and the second transition roller 64; the inclined surface 63 is located below the first transition roller 62 and the second transition roller 64.
Specifically, the horizontal supporting rod and roller driving device 70 includes a horizontal supporting rod and a driving device for driving the horizontal supporting rod to rotate; and a guide roller is arranged in front of the horizontal support rod.
The output of the bag is completed by a horizontal support rod and a roller driving device 70, the horizontal support rod is connected with the driving device through a belt wheel, and a guide roller rolls along with the horizontal support rod. When the driving device rotates for a certain angle, the horizontal supporting rod and the guide roller rotate for a corresponding angle, the coiled bag is pulled out for a certain distance, and the pulled-out distance is used for conveying of the rear cutting mechanism. The driving device adopts a stepping motor, and after the stepping motor rotates for a certain angle, the length of the pulled bag is far greater than the total length of one bag, because the following bag cutting mechanism is also provided with a roller mechanism for pulling out the length of one bag for cutting. And the roller guide conveying is arranged between the conveying mechanism and the cutting mechanism, so that the distance of one-time pulling-out is enough for later transmission. The horizontal support rod in the bag conveying mechanism is selected from stainless steel long pipe rollers. Polyurethane is added to the outer layer of the guide roller, so that friction between the guide roller and the driving roller can be reduced.
The cutting part of the bag cutting mechanism 50 is at the foremost end of the mechanism, and the detailed structure is shown in fig. 5. The front end of the cutting part is provided with a conveying device 60 for rolled bags, the front of the conveying device 60 for rolled bags is used for conveying the bags, the foremost end is also provided with two rollers, a second transition roller 64 and a third transition roller 65, and the main function is guiding function and guiding the bags to the lower side.
The rolled bag conveying device 60 comprises a conveying rack 61; a first transition roller 62 is arranged on the conveying frame 61; an input frame is arranged above one end of the conveying rack 61; the bag conveying roller 52 is positioned at the other end of the conveying frame 61; a second transition roller 64 and a third transition roller 65 are arranged on the input frame; an inclined surface 63 is arranged between the first transition roller 62 and the second transition roller 64; the inclined surface 63 is located below the first transition roller 62 and the second transition roller 64.
An inclined surface 63 is arranged between the first transition roller 62 and the second transition roller 64; the inclined surface 63 may be welded to the frame or may be fixed to the frame by other fixing means. Its main function is to straighten the bag in preparation for subsequent severing. The bag also has a roller first transition roller 62 in front of it, which roller has the function of preventing the bag from jumping upwards when being conveyed and pulled out by the roller, thus causing conveying errors. Although the three rollers in the mechanism have different functions, the three rollers have the same working principle, so that the same guide roller can be selected and used, and the type of the guide roller is the same as that of the driving roller of the conveying mechanism. The cutting mechanism is a cutting part at the most front end, and the bag conveying mechanism is connected with the cutting mechanism after the cutting mechanism comes out. The bag is cut by 'hot cutting', namely, the bag is cut by a heated cutter, and the cutter is provided with a heating device, so that the cutter can be heated to cut the bag during operation. The hot cutting has the advantages that the end face of the cut bag is relatively regular, and the bag has good positioning effect on smoothly finishing edge folding and edge sewing at the back.
The working principle of the whole cutting mechanism is as follows: after the bag is fed out by the roller conveyor, the second telescopic device 58 above starts to operate, pushing the sliding plate 54 downwards, and the lower part of the sliding plate 54 is also provided with a guide shaft. The connecting rod 56 is connected with the edge pressing block, when moving downwards, the edge pressing block can touch the conveying table due to the fact that a groove is formed below the cutter, and the connecting rod 56 is provided with a spring. When the edge pressing block touches the workbench to press the bag, the spring starts to work when the edge pressing block continues to move downwards, and the cutter continues to cut off the bag downwards. After the cutting, the second telescopic device 58 moves upwards to drive the lower part to move upwards together, so that the whole cutting process is completed. The guide shaft is arranged in a linear bearing, and the linear bearing is selected to be of a flange type, so that the linear bearing is convenient to install.
For the convenience of control, further, the first telescopic device 311 and the second telescopic device 58 are both a pneumatic cylinder, a hydraulic cylinder or an electric push rod.
Specifically, the roller conveyor belt bag feeding mechanism 10 is connected with the bag cutting mechanism 50, the roller conveyor belt bag feeding mechanism 10 can be divided into three parts, the front part is a part connected with the bag cutting mechanism 50, the middle part is provided with a sewing edge sewing mechanism, and the last part is a bag conveying part. The whole mechanism is shown in figure 4.
The connection part with the bag cutting mechanism mainly has the function that after the bags are cut off, the cut bags are conveyed to the edge sewing mechanism 40 by the roller conveyor belt; as shown in fig. 4, in particular, after the bag is cut off, one side of the bag is already on the roller and the conveyor belt, the roller conveyor belt bag feeding mechanism 10 comprises the conveyor belt, three small rollers are arranged on the roller of the conveyor belt, the small rollers are arranged on a shaft, the shaft is arranged on a frame through a bearing seat, and the shaft can rotate. The rotation of axle stretches out and contracts through the cylinder and moves, and three small roller passes through screw and nut and installs on the platelet with axle complex, and threaded hole above the platelet can be fixed epaxially, has just so guaranteed that the axle when rotating, and the small roller fixed plate just can not rotate. After the bag is cut off, the cylinder stretches out to move, the small roller is driven by the shaft to contact with the belt, and the roller and the belt move to convey the bag to the conveying belt. Since a portion of the cut bag is already on the belt, the small rollers rotate in opposite directions as long as they contact the belt in a downward direction, similar to the meshing of gears, to "pinch" the bag into the belt. The bags are transferred to the rear hemming mechanism 40 by beginning the transfer after entering the conveyor. The conveyor belt of the hemming mechanism 40 also carries a number of small rollers, which are different from the previous ones, which are roller bearing followers, mounted on a fixed plate mounted on a shaft axially positioned by a positioning ring. The follower follows the rotation of the conveyor belt to convey the bag and prevent inaccurate positioning of the bag during edge sewing. The edge sewing mechanism is arranged beside the shelf and mainly comprises a flanging plate and a sewing machine, and the working principle is that after the bag is conveyed, the sewing machine stitches the bag after the bag passes through the flanging mechanism, the sewing machine cuts off a sewing line after sewing, and the subsequent work is carried out after cutting off.
The last part of the bag conveying and edge sewing mechanism is a conveying part which is connected with a subsequent roller plate turning mechanism to turn the sewn bag conveying belt over the plate, and the bag is conveyed to a subsequent bag feeding mechanism by the plate turning mechanism for subsequent bagging work.
