Technical Field
[0001] This utility model relates to the technical field of composite film pressing and feeding device for packaging bag processing, and in particular to a composite film pressing and feeding device for packaging bag processing. Background Technology
[0002] A loading rack is a device for loading items. It is used when pressing and loading composite films for packaging bags.
[0003] The inventors discovered during routine use of the feeding rack that when the amount of composite film wrapped around the surface of the feeding roller is insufficient, the composite film may slip on the surface of the feeding roller, which would prevent the composite film from being fed properly, thus preventing the packaging bags from being pressed together effectively, and causing other problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a composite film pressing and feeding device for packaging bag processing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a packaging bag processing composite film pressing and feeding device, including a feeding frame, a bearing fixedly connected to the top of the feeding frame, a feeding roller rotatably connected inside the bearing, a bracket fixedly connected to the surface of the feeding roller, a fixing device provided on the side of the bracket, the fixing device including a rectangular groove opened on the side of the bracket, a threaded rod threadedly connected to the inner wall of the rectangular groove, an extrusion plate rotatably connected to one end of the threaded rod, a sliding rod slidably connected inside the rectangular groove, and an extrusion plate fixedly connected to one end of the sliding rod.
[0006] The effect achieved by the above components is as follows: under the action of the threaded rod, the extrusion plate extrudes and fixes the composite film inside the rectangular groove, thereby achieving the function of fixing the composite film and avoiding the phenomenon of the composite film slipping on the surface of the feeding roller. When it is necessary to feed and press the composite film of the packaging bag, the feeding roller is inserted into the bearing and one end of the composite film is pulled out for pressing, thereby achieving the function of feeding the composite film.
[0007] Preferably, a conical block is fixedly connected to the side of the extrusion plate, and the conical block abuts against the inner wall of the rectangular groove.
[0008] The effect achieved by the above components is that, under the action of the conical block, the composite membrane will not slip out of the rectangular groove, thus achieving the effect of fixation.
[0009] Preferably, a pad, which is a rubber plate, is fixedly connected to the inner wall of the rectangular groove.
[0010] The effect achieved by the above components is that, under the action of the pad, the conical block will not directly contact the inner wall of the rectangular groove, thus avoiding the phenomenon of the support being squeezed and deformed by the conical block.
[0011] Preferably, the side of the bracket is threaded with a bolt, one end of which abuts against the surface of the slide rod.
[0012] The effect achieved by the above components is as follows: under the action of the bolts, the position of the slide bar can be fixed, avoiding the phenomenon of extrusion plate displacement. When preventing one end of the composite film from being fixed on the surface of the bracket, the composite film is inserted into the inside of the rectangular groove. By hand-tightening the threaded rod, under the action of the slide bar, the extrusion plate will not rotate with the rotation of the threaded rod. This causes the extrusion plate to push the conical block to press the composite film onto the surface of the pad, thereby fixing the composite film to the inner wall of the rectangular groove. This fixes one end of the composite film to the surface of the feeding roller, thus achieving the function of fixing the composite film.
[0013] Preferably, a lubrication device is fixedly connected to the surface of the bearing, a lubrication frame is fixedly connected to the top of the bearing, a pipe is fixedly connected to the bottom of the lubrication frame, a corrugated pipe is fixedly connected to the surface of the lubrication frame, and an extrusion block is fixedly connected to the surface of the feeding roller.
[0014] The effect achieved by the above components is that, under the action of the lubrication frame and the extrusion block, the bearing can be smoothly slid, thereby allowing the feeding roller to rotate smoothly inside the bearing.
[0015] Preferably, a pad, which is a rubber block, is fixedly connected to the side of the extrusion block.
[0016] The effect achieved by the above components is that, under the action of the pad, the extrusion block will not directly contact the side of the lubrication frame, thereby avoiding the phenomenon of the lubrication frame being deformed by impact.
[0017] Preferably, a damper is fixedly connected inside the lubrication frame, and the two ends of the damper are fixedly connected to the two sides of the inner wall of the lubrication frame, respectively.
[0018] The effect achieved by the above components is that, under the action of the damper, the lubrication frame can be reset when it is not squeezed by the squeezing block, thereby achieving the reset function.
[0019] Preferably, a valve is fixedly connected to the inner wall of the pipe, and the valve is a one-way channel.
[0020] The effect achieved by the above components is as follows: under the action of the valve, the lubricating fluid inside the lubrication frame flows out. When the bearing needs to be lubricated, when the feeding roller rotates inside the bearing, the extrusion block deforms the lubrication frame under the action of the bellows, thereby causing the valve to be opened, and the lubricating fluid flows out through the pipe. When the extrusion block separates from the lubrication frame, the lubrication frame is reset under the action of the damper, and then is extruded again to spray out the lubricating fluid, thereby achieving the lubrication effect.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting a fixing device, when preventing one end of the composite film from being fixed on the surface of the bracket, the composite film is inserted into the inside of the rectangular groove. By turning the threaded rod by hand, under the action of the sliding rod, the extrusion plate will not rotate with the rotation of the threaded rod. This causes the extrusion plate to push the conical block to press the composite film onto the surface of the pad, thereby fixing the composite film to the inner wall of the rectangular groove. This fixes one end of the composite film to the surface of the feeding roller, thus achieving the function of fixing the composite film and solving the problem that the composite film wrapped around the surface of the feeding roller is prone to loosening.

[0028] Example 1, as Figure 1A composite film pressing and feeding device for packaging bag processing includes a feeding frame 1, a bearing 5 fixedly connected to the top of the feeding frame 1, a feeding roller 4 rotatably connected inside the bearing 5, a bracket 6 fixedly connected to the surface of the feeding roller 4, and a fixing device 2 provided on the side of the bracket 6.
[0029] Working principle: When it is necessary to feed and press the composite film of the packaging bag, the feeding roller 4 is inserted into the bearing 5, and one end of the composite film is pulled out for pressing, thereby achieving the function of feeding the composite film.
[0030] Reference Figure 2 The fixing device 2 includes a rectangular groove 21 formed on the side of the bracket 6. A threaded rod 22 is threadedly connected to the inner wall of the rectangular groove 21. One end of the threaded rod 22 is rotatably connected to a pressing plate 23. A sliding rod 26 is slidably connected inside the rectangular groove 21. One end of the sliding rod 26 is fixedly connected to the pressing plate 23. A conical block 24 is fixedly connected to the side of the pressing plate 23. The conical block 24 abuts against the inner wall of the rectangular groove 21. A pad 25, which is a rubber plate, is fixedly connected to the inner wall of the rectangular groove 21. A bolt 27 is threadedly connected to the side of the bracket 6. One end of the bolt 27 abuts against the surface of the sliding rod 26.
[0031] Working principle: When preventing one end of the composite film from being fixed on the surface of the bracket 6, the composite film is inserted into the rectangular groove 21. The threaded rod 22 is turned by hand. Under the action of the sliding rod 26, the extrusion plate 23 will not rotate with the rotation of the threaded rod 22. This causes the extrusion plate 23 to push the conical block 24 to press the composite film onto the surface of the pad 25, thereby fixing the composite film to the inner wall of the rectangular groove 21. This fixes one end of the composite film to the surface of the feeding roller 4, thus achieving the function of fixing the composite film.
[0032] Reference Figure 3-4 A lubrication device 3 is fixedly connected to the surface of bearing 5. A lubrication frame 31 is fixedly connected to the top of bearing 5. A pipe 36 is fixedly connected to the bottom of lubrication frame 31. A bellows 35 is fixedly connected to the surface of lubrication frame 31. An extrusion block 33 is fixedly connected to the surface of feeding roller 4. A pad 34, which is a rubber block, is fixedly connected to the side of extrusion block 33. A damper 32 is fixedly connected inside lubrication frame 31. The two ends of damper 32 are fixedly connected to the inner walls of lubrication frame 31 respectively. A valve 37, which is a one-way channel, is fixedly connected to the inner wall of pipe 36.
[0033] Working principle: When lubrication of bearing 5 is required, when the feeding roller 4 rotates inside bearing 5, the extrusion block 33 deforms the lubrication frame 31 under the action of the bellows 35, thereby causing the valve 37 to be opened, and the lubricant to flow out through the pipe 36. When the extrusion block 33 separates from the lubrication frame 31, the lubrication frame 31 is reset under the action of the damper 32, and is then extruded again to spray out the lubricant, thereby achieving the lubrication effect.
