Technical Field
[0001] This utility model relates to the field of plastic bag storage technology, and in particular to a storage device for a bag making machine used in plastic bag production. Background Technology
[0002] The collection device of a bag-making machine for plastic bag production refers to the component or system used to collect and sort the finished plastic bags. It includes a receiving platform or receiving rack on which the plastic bags produced by the bag-making machine fall in sequence for the operator to sort and package.
[0003] A search revealed Chinese patent publication number CN217201240U, which discloses a cold-cutting bag-making machine with a finished product storage mechanism for plastic bag production. The machine includes a cold-cutting bag-making device. A discharge plate is fixedly connected to the inner front end of the cold-cutting bag-making device. A first slider is slidably connected to the inner right end of the cold-cutting bag-making device. A housing is fixedly connected to the right end of the first slider. A second slider is slidably connected to the inner side of the housing. A storage box is fixedly connected between the left and right ends of the second slider. A tray is fixedly connected to the bottom end of the storage box. The bottom end of the tray... A threaded shaft is connected to the side thread, and a first gear is fixedly connected to the outer bottom end of the threaded shaft. A second gear is meshed with the outer left end of the first gear. The interior of the storage box can be separated by a partition, so that the plastic bags can be stored more neatly and orderly. At the same time, the position of the partition can be adjusted according to the size of the plastic bags to facilitate the storage of plastic bags of different sizes. However, the storage device of the existing bag making machine used for plastic bag production stores the plastic bags directly after cutting. But wrinkles or bulges will occur when cutting the plastic bags, which will lead to the problem of not being able to bundle them in a quantitative manner. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a storage device for a bag-making machine used in plastic bag production, which aims to improve the problem in the prior art that wrinkles or bulges occur when cutting plastic bags, resulting in the inability to quantitatively bundle them.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a storage device for a bag-making machine for producing plastic bags, comprising a frame, a motor fixedly connected to the top of the frame, a turntable fixedly connected to the output end of the motor, a connecting rod rotatably connected to the left side of the turntable, a pushing rod rotatably connected to the lower right end of the connecting rod, a pressure plate fixedly connected to the bottom of the pushing rod, a threaded rod rotatably connected to the inner side of the pressure plate, a rotating handle fixedly connected to the front end of the threaded rod, two rubber pads threaded at equal intervals to the outer wall of the threaded rod, and a stacking mechanism installed on the inner front end of the frame for stacking plastic bags.
[0006] The above technical solution works as follows: the power provided by motor one drives the rotation of the turntable. The rotation of the turntable causes the connecting rod to move along a trajectory, which in turn drives the push rod to move up and down. This push rod, in turn, drives the pressure plate to move up and down, thereby flattening the plastic bag through the two rubber pads installed under the pressure plate. If different sizes of plastic bags are encountered, the handle installed on the front side of the pressure plate can be rotated. The handle drives the threaded rod to rotate, which in turn drives the two rubber pads to move to both sides through the thread, thus flattening the plastic bags of different sizes.
[0007] As a further description of the above technical solution:
[0008] The stacking mechanism includes a second motor, the bottom of which is fixedly connected to the right front end of the inner bottom wall of the frame. A gear is fixedly connected to the output end of the second motor. A rack is slidably connected to the lower middle part of the inner front end of the frame. The rack and the gear are meshed together. A stacking plate is fixedly connected to the top of the rack. Two L-plates are fixedly connected at equal intervals to the middle of the inner front end of the frame. A sensor is fixedly connected to the top of each adjacent side of the two L-plates.
[0009] Through the above technical solution: plastic bags fall onto the stacking plate. During this period, the two L-plates can calibrate the falling plastic bags to avoid uneven stacking. When the plastic bags on the stacking plate reach a certain thickness, they will be detected by the corresponding sensors fixed on the two L-plates. Then, the sensors will send a signal to the second motor to start it. Subsequently, the power provided by the second motor drives the gear to rotate. When the gear rotates, it will mesh with the rack and drive it to move downward. At the same time, the rack will drive the stacking plate to move downward synchronously, so that the stacking plate can stack more plastic bags.
[0010] As a further description of the above technical solution:
[0011] Multiple anti-slip sleeves are equidistantly installed on the outer wall of the handle, and Velcro is fixedly connected to the left and right sides of the outer wall of each of the multiple anti-slip sleeves.
[0012] The above technical solution improves the anti-slip properties of the handle by using a Velcro-attached anti-slip sleeve.
[0013] As a further description of the above technical solution:
[0014] A conveyor belt is installed in the middle of the inner side of the frame, and a motor is fixedly connected to the left front end of the conveyor belt.
[0015] The above technical solution enables the conveyor belt powered by motor three to transport plastic bags.
[0016] As a further description of the above technical solution:
[0017] Both the first motor and the second motor are fixedly connected to a stabilizing frame at their bottoms, and screws are threaded onto the front, rear, left, and right ends of both stabilizing frames.
[0018] The above technical solution: the stabilizer fixed by screw one can improve the stability of motor two.
[0019] As a further description of the above technical solution:
[0020] Limiting strips are installed on both the left and right sides of the outer wall of the conveyor belt, and multiple thumbtacks are fixedly connected to the top of each of the two limiting strips at equal intervals.
[0021] The above technical solution uses a limit strip fixed to the conveyor belt with a thumbtack to prevent the plastic bags from shifting during transport.
[0022] As a further description of the above technical solution:
[0023] X-shaped brackets are installed on both the left and right sides of the frame, and screws are threaded to the four corners of the X-shaped brackets.
[0024] The above technical solution, which uses screws to fix the X-shaped frame, can improve the stability of the frame.
[0025] As a further description of the above technical solution:
[0026] A controller is fixedly connected to the left side of the front center of the frame, and multiple function keys are installed at equal intervals on the right side of the controller.
[0027] The above technical solution allows for the adjustment of the storage device of the bag-making machine used for plastic bag production via the function keys on the controller.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, the motor drives two rubber pads to flatten the plastic bag through a turntable, connecting rod, push rod and pressure plate. The rotation of the handle drives the rotation of the threaded rod, thereby moving the two rubber pads to both sides, thus flattening plastic bags of different sizes, thereby avoiding wrinkles or bulges in the plastic bags during storage, thus completing the subsequent quantitative bundling.
[0030] 2. In this utility model, when the plastic bag falls onto the stacking plate, the two L-plates can calibrate it. When the plastic bag reaches a certain thickness, the sensor will send a signal to the second motor to start it. The second motor drives the stacking plate to move down through gears and racks, so that the stacking plate can stack more plastic bags, thereby achieving the stacking effect of plastic bags.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0039] Reference Figure 2 and Figure 3This utility model provides an embodiment of a storage device for a bag-making machine used in plastic bag production, comprising a frame 1, a motor 3 fixedly connected to the top of the frame 1, a turntable 4 fixedly connected to the output end of the motor 3, the motor 3 driving the turntable 4 to rotate, a connecting rod 5 rotatably connected to the left side of the turntable 4, a push rod 6 rotatably connected to the lower right end of the connecting rod 5, a pressure plate 7 fixedly connected to the bottom of the push rod 6, the connecting rod 5 driving the pressure plate 7 to move up and down through the push rod 6, a threaded rod 8 rotatably connected to the inner side of the pressure plate 7, and a handle 9 fixedly connected to the front end of the threaded rod 8. Two rubber pads 10 are equidistantly threaded to the outer wall of the threaded rod 8. The handle 9 adjusts the distance between the two rubber pads 10 through the threaded rod 8. A stacking mechanism 2 is installed on the inner front end of the frame 1. The stacking mechanism 2 is used to stack plastic bags. Multiple anti-slip sleeves 11 are equidistantly installed on the outer wall of the handle 9. Velcro 12 is fixedly connected to the left and right sides of the outer wall of the multiple anti-slip sleeves 11. Velcro 12 is used to fix the anti-slip sleeves 11. A conveyor belt 14 is installed in the middle of the inner side of the frame 1. A motor 3 13 is fixedly connected to the left front end of the conveyor belt 14. The motor 3 13 drives the conveyor belt 14 to rotate.
[0040] Specifically, the rotation of turntable 4 is driven by the power provided by motor 3. The rotation of turntable 4 causes connecting rod 5 to move along a track, which in turn drives push rod 6 to move up and down. This, in turn, drives pressure plate 7 to move up and down, thereby flattening the plastic bag through two rubber pads 10 installed under pressure plate 7. If different sizes of plastic bags are encountered, the handle 9 installed on the front side of pressure plate 7 can be rotated. The handle 9 drives threaded rod 8 to rotate, which in turn drives the two rubber pads 10 to move to both sides through the thread, thus flattening the plastic bags of different sizes. The anti-slip sleeve 11 fixed to the outside of handle 9 by Velcro 12 can improve its anti-slip performance. The conveyor belt 14 driven by motor 3 can transport the plastic bags.
[0041] Reference Figure 4 and Figure 5The stacking mechanism 2 includes a second motor 201. The bottom of the second motor 201 is fixedly connected to the right side of the inner bottom wall of the frame 1. A gear 202 is fixedly connected to the output end of the second motor 201. The second motor 201 drives the gear 202 to rotate. A rack 203 is slidably connected to the lower middle part of the inner front end of the frame 1. The rack 203 and the gear 202 are meshed. A stacking plate 204 is fixedly connected to the top of the rack 203. The gear 202 moves the stacking plate 204 downward through the rack 203. Two L-plates 205 are fixedly connected at equal intervals to the middle of the inner front end of the frame 1. The L-plates 205 limit the plastic bags. A sensor 206 is fixedly connected to the top of the adjacent side of the two L-plates 205. The sensor 206 is used to detect the stacking height. A stabilizing frame 15 is fixedly connected to the bottom of the first motor 3 and the second motor 201. A screw 16 is threadedly connected to the front, back, left and right ends of the two stabilizing frames 15. The screw 16 is used to fix the stabilizing frame 15.
[0042] Specifically, the plastic bags fall onto the stacking plate 204. During this time, the two L-plates 205 can calibrate the falling plastic bags to prevent them from being stacked unevenly. When the plastic bags on the stacking plate 204 reach a certain thickness, they will be detected by the corresponding sensors 206 fixed on the two L-plates 205. Then, the sensors 206 will send a signal to the second motor 201 to start it. Subsequently, the power provided by the second motor 201 drives the gear 202 to rotate. When the gear 202 rotates, it will mesh with the rack 203, thereby driving it to move downward. At the same time, the rack 203 will drive the stacking plate 204 to move downward synchronously, so that the stacking plate 204 can stack more plastic bags. The stabilizing frame 15, which is fixed by the screw 16, can improve the stability of the second motor 201.
[0043] Reference Figure 1 and Figure 2 Limiting strips 17 are installed on both the left and right sides of the outer wall of the conveyor belt 14. Multiple tacks 18 are fixedly connected at equal intervals to the top of each limiting strip 17. The tacks 18 are used to fix the limiting strips 17. X-shaped frames 19 are installed on both the left and right sides of the frame 1. Screws 20 are threadedly connected to the four corners of the X-shaped frame 19. Screws 20 are used to fix the X-shaped frame 19. A controller 21 is fixedly connected to the left side of the front middle of the frame 1. Multiple function keys 22 are installed at equal intervals on the right side of the controller 21. The function keys 22 are used to start the controller 21.
[0044] Specifically, the limiting strip 17, which is fixed to the conveyor belt 14 by the thumbtack 18, can prevent the plastic bags from shifting during transport. The X-shaped frame 19, which is fixed by the screw 20, can improve the stability of the frame 1. The storage device of the bag making machine for plastic bag production can be adjusted by the function key 22 on the controller 21.
[0045] Working principle: When the plastic bag making machine's storage device is used to store plastic bags, the motor 3 is started when the plastic bag is conveyed to the pressure plate 7. The power provided by the motor 3 drives the turntable 4 to rotate. The rotation of the turntable 4 drives the connecting rod 5 to move along the track, which in turn drives the push rod 6 to move up and down. This, in turn, drives the pressure plate 7 to move up and down. The two rubber pads 10 installed under the pressure plate 7 flatten the plastic bag. If different sizes of plastic bags are encountered, the handle 9 installed on the front side of the pressure plate 7 can be rotated. The handle 9 drives the threaded rod 8 to rotate, which in turn drives the two rubber pads 10 to move to both sides through the thread, thus flattening the plastic bags of different sizes. This achieves the effect of avoiding wrinkles or bulges in the plastic bags during storage, thus completing the subsequent quantitative bundling.
[0046] After the bag-making machine flattens the plastic bag, it continues to be conveyed forward and falls onto the stacking plate 204. During this process, the two L-plates 205 calibrate the falling plastic bags to prevent them from stacking unevenly. When the plastic bags on the stacking plate 204 reach a certain thickness, they are detected by the corresponding sensors 206 fixed on the two L-plates 205. The sensors 206 then send a signal to the motor 201 to start it. The power provided by the motor 201 drives the gear 202 to rotate. When the gear 202 rotates, it meshes with the rack 203, causing it to move downward. At the same time, the rack 203 moves the stacking plate 204 downward, allowing the stacking plate 204 to stack more plastic bags, thus achieving a stacking effect for the plastic bags and facilitating subsequent bundling.
[0047] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
