Description

Technical Field

[0001] This utility model relates to the field of plastic bag processing technology, and in particular to a high-quality flattening device for plastic bags. Background Technology

[0002] Plastic bags are bags made primarily of plastic. They are essential items in daily life and are often used to hold other items. They have the advantages of being inexpensive, extremely lightweight, having a large capacity, and being easy to store. In order to facilitate the flattening of plastic bags during production, processing, and recycling, a high-quality plastic bag flattening treatment device is needed.

[0003] A search revealed Chinese patent publication number CN211542610U, which discloses a leveling device for processing plastic bags. The device includes a horizontal plate, a leveling mechanism, and a guiding mechanism. The leveling mechanism is mounted above the horizontal plate, and the guiding mechanism is located behind it. It also includes a lifting mechanism installed below the horizontal plate. This invention allows for adjustment of the horizontal plate's height through the lifting mechanism, enabling the device to meet different usage requirements. The guiding mechanism increases the traction force on the plastic film during leveling, thus improving the leveling effect. However, in practical use, it is difficult to inspect the leveling effect of the plastic bag after leveling and to repeatedly level any uneven areas, thereby reducing the device's reliability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-quality flattening device for plastic bags, which aims to improve the problem that the existing flattening devices are not convenient for detecting and repeatedly flattening plastic bags.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-quality flattening device for plastic bags, comprising a base, electric rollers rotatably connected to the left and right sides of the inner wall of the base, a first rotating wheel fixedly connected to the front side of the electric rollers through the base, a perforated belt provided on the outer side of the first rotating wheel, and the two first rotating wheels being connected by the perforated belt for transmission; a flat plate fixedly connected to the middle of the inner wall of the base, a gear rotatably connected to the front end of the flat plate, the gear meshing with the perforated belt, a rubber roller fixedly connected to the rear side of the gear through the base, a rotating rod rotatably connected to the middle of the inner wall of the flat plate, telescopic plates fixedly connected to the front and rear sides of the outer wall of the rotating rod, a pressure plate rotatably connected to the left side of the telescopic plate, a connecting rod fixedly connected to the top of the flat plate, springs fixedly connected to the front and rear sides of the bottom of the connecting rod, a rotating roller rotatably connected to the bottom of the springs, and a positioning mechanism provided on the inner side of the base for adjusting the flattening force.

[0006] The above technical solution involves wrapping the flattened plastic bag around the outside of the electric roller, placing it on the leveling plate, and starting the electric roller. The plastic bag is then driven to level itself. After initial leveling, the folds lift the rotating roller, the compression spring tightens, and the telescopic plate extends and rotates, pushing the pressure plate to press the rubber roller. At the same time, the rotation of the electric roller drives the first rotating wheel and the perforated belt to mesh with the transmission gear and the rubber roller, achieving further leveling of the plastic bag. The leveling process is carried out while the effect is being inspected.

[0007] As a further description of the above technical solution:

[0008] The positioning mechanism includes a top plate, which is fixedly connected to the top right side of the base. The bottom front and rear sides of the top plate are rotatably connected to second rotating wheels. A belt is provided on the outer side of the second rotating wheels, and the two second rotating wheels are connected to each other by belt drive. A bidirectional threaded rod is fixedly connected to the bottom of the second rotating wheel. U-shaped plates are meshed with the upper and lower sides of the outer wall of the bidirectional threaded rod. Rotating plates are rotatably connected to the left and right sides of the inner wall of the U-shaped plates. A squeezing roller is rotatably connected to the outer side of the rotating plates.

[0009] Through the above technical solution: the belt drive synchronously drives the second rotating wheel and the bidirectional threaded rod to rotate. The threaded rod drives the U-shaped plate to move up and down through the threaded connection. The movement of the U-shaped plate causes the inner rotating plate to rotate, which drives the extrusion roller to move and apply pressure, thereby adjusting the extrusion and flattening effect. The flattening degree of the device can be flexibly adjusted according to actual needs.

[0010] As a further description of the above technical solution:

[0011] The top plate has knobs rotatably connected to both the front and rear sides of its top, and the bottom of each knob passes through the top plate and is fixedly connected to the second rotating wheel.

[0012] The above technical solution allows for easy rotation of the second rotating wheel via a knob.

[0013] As a further description of the above technical solution:

[0014] The base has handles fixedly connected to the front and rear sides of the middle of its outer wall, and a protective sleeve is fixedly connected to the outside of the handles.

[0015] The above technical solution allows for easy gripping and handling of the device via the handle and its protective sleeve.

[0016] As a further description of the above technical solution:

[0017] Positioning blocks are fixedly connected to all four sides of the outer wall of the base, and positioning holes are provided on the outer side of the positioning blocks.

[0018] The above technical solution allows for the installation and fixation of the device by installing threaded parts in the positioning holes on the outside of the positioning block.

[0020] The bottom of the flat plate is fixedly connected to a bracket around its four sides, and the outer side of the bracket is fixedly connected to the base.

[0021] The above technical solution can improve the structural strength and stability of the device by using a support frame.

[0022] As a further description of the above technical solution:

[0023] A groove is provided on the top left side of the flat plate, and a heating plate is fixedly connected to the inside of the groove.

[0024] The above technical solution allows for easy lifting of the plastic bag by activating the heating plate.

[0025] As a further description of the above technical solution:

[0026] A controller is fixedly connected to the rear side of the base, and the controller is electrically connected to the electric roller and the heating plate respectively.

[0027] The above technical solution allows the controller to control the start-up of the electric roller and the heating plate.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, a flattened plastic bag is wrapped and fixed to the outside of an electric roller, placed on a leveling plate for flattening, and then the electric roller is started to drive the plastic bag to be leveled. After initial leveling, the folds in the plastic bag push up the rotating roller to compress the spring. The spring tightens, causing the telescopic plate to extend and rotate, pushing the pressure plate to apply pressure to the rubber roller. At the same time, the rotation of the electric roller drives the first rotating wheel and the multi-hole belt to mesh with the transmission gear and the rubber roller, leveling the plastic bag again. The leveling effect can be checked and leveled again while leveling, thereby improving the reliability of the device.

[0030] 2. In this utility model, the second rotating wheel and the bidirectional threaded rod are synchronously driven by belt transmission. The rotation of the threaded rod causes the U-shaped plate to move up and down through the threaded connection. The movement of the U-shaped plate drives the inner rotating plate to rotate, thereby causing the extrusion roller to move and apply pressure, adjusting the degree of extrusion and flattening. The flattening degree of the device can be adjusted according to actual needs, thereby improving the practicality of the device. Attached Figure Description

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a high-quality flattening device for plastic bags, comprising a base 1, with electric rollers 3 rotatably connected to the left and right sides of the inner wall of the base 1. A first rotating wheel 22 is fixedly connected to the front side of the electric roller 3, penetrating the base 1. A perforated belt 23 is provided on the outer side of the first rotating wheel 22, and the two first rotating wheels 22 are connected by the perforated belt 23. A flat plate 4 is fixedly connected to the middle of the inner wall of the base 1, and a gear 5 is rotatably connected to the front end of the flat plate 4. The gear 5 meshes with the perforated belt 23. The rear side of the gear 5... A rubber roller 6 is fixedly connected through the base 1. A rotating rod 7 is rotatably connected to the middle of the inner wall of the flat plate 4. A telescopic plate 8 is fixedly connected to the front and rear sides of the outer wall of the rotating rod 7. A pressure plate 9 is rotatably connected to the left side of the telescopic plate 8. A connecting rod 10 is fixedly connected to the top of the flat plate 4. A spring 11 is fixedly connected to the front and rear sides of the bottom of the connecting rod 10. A rotating roller 12 is rotatably connected to the bottom of the spring 11. The bottom of the spring 11 is rotatably connected to the right side of the telescopic plate 8. A positioning mechanism 2 is provided on the inner side of the base 1. The positioning mechanism 2 is used to adjust the leveling force.

[0040] Specifically, the plastic bag is wrapped and fixed to the outer surface of the electric roller 3 as required, and then its middle part is placed on the leveling plate 4 for leveling. At this time, the electric roller 3 is started to rotate, thereby driving the plastic bag to perform transmission and leveling. After the plastic bag completes one revolution of transmission and initial leveling, the wrinkles on it will push up the corresponding rotating roller 12 and compress the spring 11. As the spring 11 contracts, it will drive the telescopic plate 8 to perform telescopic action and cause the telescopic plate 8 to rotate along the rotating rod 7. At this time, the pressure plate 9 is pushed to apply pressure to the rubber roller 6. At the same time, the rotation of the electric roller 3 will also drive the first rotating wheel 22 and its perforated belt 23 to perform transmission. Through meshing transmission, the gear 5 and the rubber roller 6 are further driven to rotate, thereby performing a second leveling process on the plastic bag.

[0041] Reference Figure 1 , Figure 2 and Figure 5The positioning mechanism 2 includes a top plate 201, which is fixedly connected to the top right side of the base 1. The bottom front and rear sides of the top plate 201 are rotatably connected to second rotating wheels 202. A belt 203 is provided on the outer side of the second rotating wheels 202. The two second rotating wheels 202 are connected by the belt 203. The belt 203 can drive the second rotating wheels 202 to rotate synchronously. The bottom of the second rotating wheel 202 is fixedly connected to a bidirectional threaded rod 204. As the second rotating wheel 202 rotates, the bidirectional threaded rod 204 can rotate synchronously. The upper and lower sides of the outer wall of the bidirectional threaded rod 204 are meshed with U-shaped plates 205. The threaded connection can drive the U-shaped plates 205 to move up and down. The left and right sides of the inner wall of the U-shaped plate 205 are rotatably connected to rotating plates 206. The outer side of the rotating plates 206 is rotatably connected to a pressing roller 207. As the U-shaped plate 205 moves, the rotating plates 206 and the pressing roller 207 on them can move.

[0042] Specifically, the belt 203 can synchronously drive the second rotating wheel 202 and its bidirectional threaded rod 204 to rotate. As the bidirectional threaded rod 204 rotates, the U-shaped plate 205 connected by the thread will move up and down. This movement will further drive the rotating plate 206 located inside the U-shaped plate 205 to rotate. The rotation of the rotating plate 206 will cause the extrusion roller 207 to move and apply pressure to it, thereby adjusting the degree of extrusion and flattening.

[0043] Reference Figure 1 , Figure 3 and Figure 5 The top plate 201 has knobs 16 rotatably connected to both the front and rear sides of its top. The bottom of the knobs 16 passes through the top plate 201 and is fixedly connected to the second rotating wheel 202. The outer wall of the base 1 has handles 17 fixedly connected to both the front and rear sides of its middle section. The outer side of the handles 17 is fixedly connected to a protective sleeve 18. The handles 17 facilitate holding and carrying the device, and the protective sleeve 18 improves the comfort of holding. The outer wall of the base 1 has positioning blocks 19 fixedly connected to all four sides. The outer side of the positioning blocks 19 has positioning holes 20. By installing threaded parts in the positioning holes 20 on the positioning blocks 19, the device can be easily fixed.

[0044] Specifically, the second rotating wheel 202 can be manually rotated by turning the knob 16, the device can be easily moved and stored by holding the handle 17, and the protective sleeve 18 on it can improve the comfort of holding it. The device can be easily installed and fixed by installing threaded parts in the positioning hole 20 on the positioning block 19.

[0045] Reference Figure 1 , Figure 3 and Figure 4The bottom of the flat plate 4 is fixedly connected to the support 15 on all four sides. The outer side of the support 15 is fixedly connected to the base 1. The support 15 can improve the fixed firmness between the flat plate 4 and the base 1. The top left side of the flat plate 4 is provided with a groove 13. The inner side of the groove 13 is fixedly connected to a heating plate 14. Activating the heating plate 14 can heat the plastic bag to assist in leveling. The rear side of the base 1 is fixedly connected to a controller 21. The controller 21 is electrically connected to the electric roller 3 and the heating plate 14 respectively.

[0046] Specifically, the support and fixation of the bracket 15 can improve the firmness of the fixation between the base 1 and the flat plate 4. By activating the heating plate 14 inside the groove 13, the plastic bag on the flat plate 4 can be heated to assist in leveling. The controller 21 can control the starting and running power of the electric roller 3 and the heating plate 14 respectively. The controller 12 can be an S7-1200 type, the electric roller 3 can be a TDY75 type, and the heating plate 14 can be a JRD type heating plate.

[0047] Working principle: Before using the device, the plastic bag to be flattened is first wrapped and fixed around the outside of the electric roller 3, and its middle part is placed on the leveling plate 4 for flattening. At this time, the electric roller 3 is started to rotate to drive the plastic bag to drive and flatten. After one revolution of transmission and flattening, the wrinkled part of the plastic bag will push up the corresponding rotating roller 12 and squeeze the spring 11. As the spring 11 tightens, it drives the telescopic plate 8 to extend and retract and rotate along the rotating rod 7 to push the pressure plate 9 to apply pressure to the rubber roller 6. At this time, as the electric roller 3 rotates, it drives the first rotating wheel 22 and its perforated belt 23 to drive the gear 5 and the rubber roller 6 to rotate through meshing transmission, so as to flatten the plastic bag again.

[0048] Furthermore, the belt 203 can synchronously drive the second rotating wheel 202 and its bidirectional threaded rod 204 to rotate. At this time, as the bidirectional threaded rod 204 rotates, it can drive the U-shaped plate 205 to move up and down through the threaded connection. As the U-shaped plate 205 moves, it can drive the rotating plate 206 on its inner side to rotate. As the rotating plate 206 rotates, it drives the extrusion roller 207 to move and apply pressure, thereby adjusting the degree of extrusion and flattening.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
