Description

Technical Field

[0001] This utility model relates to the field of plastic film production technology, specifically to a plastic film roll conveying device. Background Technology

[0002] Plastic films are films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging and as a coating layer. Plastic packaging and plastic packaging products are gaining an increasingly larger market share, especially composite plastic flexible packaging, which is widely used in the food, pharmaceutical, and chemical industries. Food packaging accounts for the largest proportion, including beverage packaging, frozen food packaging, retortable food packaging, and fast food packaging. These products have brought great convenience to people's lives.

[0003] After plastic film production, it is generally wound up and placed using a winding roller. After winding, the plastic film rolls are stacked together. Since the wound plastic film is relatively heavy, it is usually clamped and moved by a robotic arm to transport it to a suitable position. However, when the plastic film rolls are placed close together, it is very inconvenient to clamp them directly because the clamping arms are generally arc-shaped and cannot be directly inserted between the plastic film rolls. Manual movement is required, which leads to low conveying efficiency and certain safety hazards. Therefore, a plastic film roll conveying device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a plastic film roll conveying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic film roll conveying device, comprising a clamping robotic arm, a plastic film roll pushing mechanism, and a clamping arm;

[0006] The bottom of the gripping robotic arm is equipped with a symmetrically arranged plastic roll film pushing mechanism, and the bottom of the plastic roll film pushing mechanism is also fixedly connected to a gripping arm for gripping and conveying the roll film, and the bottom of the plastic roll film pushing mechanism is also fixedly connected to a guide mechanism for separating the roll film.

[0007] A soft pad is fixedly connected to the inner side of the clamping arm;

[0008] The guiding mechanism includes a connecting rod, an insertion block, and a rotating shaft. The top of the connecting rod is fixedly connected to the plastic film pushing mechanism, and the bottom of the connecting rod is fixedly connected to the insertion block. The outer periphery of the insertion block is rotatably connected to evenly distributed rotating shafts, and the outer side of each rotating shaft is fixedly connected to a guide wheel.

[0009] Furthermore, the insertion block is triangular in shape, with the tip of the insertion block pointing downwards.

[0010] Furthermore, the outer side of the guide wheel protrudes from the edge of the connecting rod.

[0011] After plastic film production, it is typically wound up and placed using take-up rollers. After winding, the plastic film rolls are stacked together. Because the wound plastic film is quite heavy, it is usually clamped and moved by a robotic arm to a suitable position. However, when the plastic film rolls are placed close together, direct clamping is inconvenient because the clamping arms are generally curved and cannot be directly inserted between the plastic film rolls, otherwise it would damage the film. Manual movement is usually required, resulting in low conveying efficiency and... There are certain safety hazards. However, when this device is in use, it is connected to the power supply. When the plastic film rolls are too close to each other for direct clamping and conveying, the plastic film push-away mechanism is activated, which drives the guide mechanism to move down. The guide mechanism can be smoothly inserted between the plastic film rolls to drive the plastic film rolls on one side to move. At this time, it is convenient for the clamping robot arm to move down and drive the plastic film push-away mechanism to move to clamp the rolls for conveying. This setting eliminates the need for manual movement of the plastic film rolls, ensuring conveying efficiency while ensuring the safety of the staff.

[0012] By moving the insertion block downwards, the pointed bottom of the insertion block facilitates insertion between the plastic film rolls. At the same time, the rotating shaft and guide wheel prevent scratching the plastic film rolls and serve as a guide, ensuring the smooth movement of the plastic film rolls.

[0013] Furthermore, the plastic roll film pushing mechanism includes a moving frame, a first motor, and a threaded rod. A guide frame is slidably connected to the outside of the moving frame, and the top of the guide frame is connected to the clamping robotic arm. The first motor is installed inside the moving frame, and a threaded rod is fixedly connected to the end of the main shaft of the first motor. A push rod sleeve is helically connected to the outside of the threaded rod, and the bottom of the push rod sleeve is fixedly connected to the guide mechanism.

[0014] Furthermore, a second motor is installed on one side of the guide frame, and a threaded shaft is fixedly connected to the end of the main shaft of the second motor. A movable sleeve is screwed to the outside of the threaded shaft, and the outside of the movable sleeve is fixedly connected to the movable frame.

[0015] Furthermore, the cross-section of the push rod sleeve is rectangular.

[0016] The first motor drives the threaded rod to rotate, which in turn moves the push rod sleeve to facilitate insertion between the plastic film rolls. At the same time, the second motor drives the threaded shaft to rotate, which facilitates the movement of the movable sleeve and the movable frame, and facilitates the movement of the plastic film roll to one side for subsequent clamping and conveying.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. When using this utility model, if the plastic film rolls are too close to each other for direct clamping and conveying, the plastic film push-away mechanism is activated to drive the guide mechanism downward. The guide mechanism can be smoothly inserted between the plastic film rolls to drive the plastic film rolls on one side to move. At this time, the clamping robot arm can be driven to move the clamping arm downward, and the clamping robot arm can drive the plastic film push-away mechanism to move to clamp the rolls for conveying. This setting eliminates the need for manual movement of the plastic film rolls, ensuring conveying efficiency while ensuring the safety of the staff.

[0019] 2. By moving the insertion block downwards, the bottom of the insertion block is set with a pointed tip, which makes it easy to insert into the plastic film roll. At the same time, the set rotating shaft and guide wheel can avoid scratching the plastic film roll and play a guiding role to ensure that the plastic film roll moves smoothly.

[0020] The first motor drives the threaded rod to rotate, which in turn moves the push rod sleeve to facilitate insertion between the plastic film rolls. At the same time, the second motor drives the threaded shaft to rotate, which facilitates the movement of the movable sleeve and the movable frame, and facilitates the movement of the plastic film roll to one side for subsequent clamping and conveying.

Detailed Implementation

[0025] 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.

[0026] Example 1: Please refer to Figure 1 and Figure 3 This utility model provides a technical solution:

[0027] A plastic film roll conveying device includes a clamping robotic arm 1, a plastic film roll pushing mechanism 2, and a clamping arm 3;

[0028] The bottom of the aforementioned clamping robotic arm 1 is equipped with a symmetrically arranged plastic roll film pushing mechanism 2, and the bottom of the plastic roll film pushing mechanism 2 is also fixedly connected with a clamping arm 3 for clamping and conveying the roll film, and the bottom of the aforementioned plastic roll film pushing mechanism 2 is also fixedly connected with a guide mechanism 4 for separating the roll film.

[0029] A soft pad 5 is fixedly connected to the inner side of the aforementioned clamping arm 3;

[0030] The aforementioned guiding mechanism 4 includes a connecting rod 401, an insertion block 402, and a rotating shaft 403. The top of the connecting rod 401 is fixedly connected to the plastic roll film pushing mechanism 2, and the bottom of the connecting rod 401 is fixedly connected to the insertion block 402. The outer periphery of the insertion block 402 is rotatably connected to the evenly distributed rotating shafts 403, and the outer sides of the rotating shafts 403 are all fixedly connected to guide wheels 404.

[0031] The aforementioned insertion block 402 is arranged in a triangle, with the tip of the insertion block 402 pointing downwards.

[0032] The outer side of the aforementioned guide wheel 404 protrudes from the edge of the connecting rod 401.

[0033] After plastic film production, it is typically wound up and placed using take-up rollers. After winding, the plastic film rolls are stacked together. Due to the weight of the wound plastic film, it is usually clamped and moved by a robotic arm to a suitable position. However, when the plastic film rolls are placed close together, direct clamping is inconvenient because the clamping arms are generally curved and cannot be directly inserted between the plastic film rolls, otherwise it would damage the film. Manual movement is usually required, resulting in low conveying efficiency and certain safety concerns. There are potential hazards. When this device is in use, it is powered on. When the plastic film rolls are too close to each other for direct clamping and conveying, the plastic film push-away mechanism 2 is activated, which drives the guide mechanism 4 to move down. The guide mechanism 4 can be smoothly inserted between the plastic film rolls to drive the plastic film rolls on one side to move. At this time, it is convenient for the clamping robot arm 1 to drive the clamping arm 3 to move down. The clamping robot arm 1 also drives the plastic film push-away mechanism 2 to move to clamp the rolls for conveying. This setting eliminates the need for manual movement of the plastic film rolls, ensuring conveying efficiency while ensuring the safety of the staff.

[0034] As the insertion block 402 moves downward, its pointed bottom facilitates insertion into the plastic film roll. The rotating shaft 403 and guide wheel 404 prevent scratching the plastic film roll and serve as guides, ensuring smooth movement of the plastic film roll. The outer side of the guide wheel 404 protrudes from the edge of the connecting rod 401, so that it does not easily damage the plastic film roll when it is pushed.

[0035] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 2 Specifically, the aforementioned plastic roll film pushing mechanism 2 includes a moving frame 201, a first motor 202, and a threaded rod 203. A guide frame 208 is slidably connected to the outer side of the moving frame 201. The top of the guide frame 208 is connected to the clamping robotic arm 1. The first motor 202 is installed inside the moving frame 201. The threaded rod 203 is fixedly connected to the end of the main shaft of the first motor 202. A push rod sleeve 204 is spirally connected to the outer side of the threaded rod 203. The bottom of the push rod sleeve 204 is fixedly connected to the guide mechanism 4.

[0036] A second motor 205 is installed on one side of the guide frame 208. A threaded shaft 206 is fixedly connected to the end of the main shaft of the second motor 205. A movable sleeve 207 is screwed to the outside of the threaded shaft 206. The outside of the movable sleeve 207 is fixedly connected to the movable frame 201.

[0037] The cross-section of the aforementioned push rod sleeve 204 is rectangular.

[0038] The first motor 202 drives the threaded rod 203 to rotate, which in turn drives the push rod sleeve 204 to move, making it easy to insert into the plastic film roll. At the same time, the second motor 205 drives the threaded shaft 206 to rotate, which makes it easy to drive the moving sleeve 207 and the moving frame 201 to move, making it easy to drive the plastic film roll to move to one side, which is convenient for subsequent clamping and conveying.

[0039] In this embodiment, since the push rod sleeve 204 is rectangular, it can be driven to slide with the moving frame 201 when the threaded shaft 206 rotates, so as to push the push rod sleeve 204 to move up and down stably and avoid its own rotation.
