[0002] Plastic film is a thin film made of plastic material. It is lightweight, flexible, transparent or translucent, and is widely used in various applications. There are many different types of plastic film, the most common of which include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyester (PET), etc. Each type of plastic film has its specific characteristics and uses. Plastic film has important applications in the packaging industry. It can be used in food packaging, pharmaceutical packaging, daily necessities packaging and other fields. The high transparency and water resistance of plastic film make it an ideal choice for cling film and packaging film. In addition, plastic film can also be used to make packaging materials such as bags, woven bags, and plastic bags. In addition to the packaging industry, plastic film is also widely used in agriculture, construction, medical and other fields. In agriculture, plastic film can be used to cover crops, provide protection and regulate the growth environment of crops. In the field of construction, plastic film can be used for waterproof layer, thermal insulation layer, etc. In the medical industry, plastic film can be used to make medical gloves, disposable surgical gowns, etc. In general, plastic film plays an important role in modern society.

[0003] Plastic film rolls are rolls of plastic film produced and wound. In the production process of plastic film, the transfer of plastic film rolls is involved. For example, the plastic film rolls collected by the plastic film production line are transferred from the production workshop to the inspection workshop for quality inspection, or the plastic film rolls are transferred to the packaging bag production workshop. In this process, transfer equipment is needed to transfer the plastic film rolls.

[0004] Prior art example 1, referring to patent document CN212579939U, discloses a coil transport device, which includes a bracket and a rolling element arranged below the bracket for moving the bracket, the bracket is provided with a plurality of vertically arranged plug-in tubes for plugging into the inner core of the plastic film roll, the plurality of plug-in tubes are evenly spaced on the bracket, and the distance between two adjacent plug-in tubes is greater than the maximum diameter of the plastic film roll, and a handle is also arranged on one side of the bracket. The present application has the effect of reducing friction between plastic film rolls and ensuring good quality of the plastic film.

[0005] Prior art example 2, referring to patent document CN215553399U, discloses a plastic film roll transport device, including a vehicle plate, both sides of the middle part of the top surface of the vehicle plate are fixedly connected with connecting ears A, the center of the connecting ear A is rotatably connected with a rotating column, the top of the rotating column is fixedly connected with a plurality of fixed rods, and one end of the two rotating columns is fixedly connected with a transmission gear; the utility model is provided with a vehicle plate, both sides of the middle part of the top surface of the vehicle plate are fixedly connected with connecting ears B, the center of the connecting ear B is rotatably connected with a rotating column, the top of the rotating column is fixedly connected with a plurality of fixed rods, and one end of the two rotating columns is fixedly connected with a transmission gear, so that when the worm rotates, the two rotating columns are driven to rotate through the two transmission gears, and the plug-in cylinder is laid down, so that the plastic film roll can be easily put in or taken out, and after being put in, the plug-in cylinder can be erected, so that it is convenient to take in and put in, thereby improving practicality.

[0006] The technologies of Example 1 and Example 2 have certain usage defects for the transportation of plastic film rolls, for example: 1. A trolley with a horizontally arranged load-bearing surface is used, and the staff needs to manually carry the plastic film roll up and down, which is very troublesome and creates a huge labor burden for the staff; 2. Due to manual handling and the fact that some plastic film rolls are heavy, once they slip out of the hands, it is easy to cause injuries to people, posing a huge safety hazard; 3. The fixing rods are all vertically upward, and they also need to be correspondingly in the vertical direction when plugging and unplugging. Operating the plastic film in this direction is likely to block the staff's line of sight, resulting in inaccurate plugging, and repeated operations are likely to cause unnecessary friction to the plastic film roll, thereby causing damage to the product.

[0043] Embodiment 1

[0044] Reference Figures 1 to 8 , a short-distance transport cart for a plastic film roll 9, comprising:

[0045] The cart has a horizontal bottom plate 1, and a plurality of rollers 11 are arranged at the bottom thereof;

[0046] A standing bracket 2, which is fixed on the horizontal bottom plate 1 of the cart in the vertical direction;

[0047] A transverse support 3, which is fixed at the middle of the standing support 2, and a handle 31 is provided on the transverse support 3;

[0048] A vertical linear drive module 4, which is assembled on the standing bracket 2;

[0049] The adapter seat 5 is transmission-connected to the vertical linear drive module 4, and the adapter seat 5 is provided with a horizontal drive device 6;

[0050] The driven support arm 7 is transmission-connected to the horizontal driving device 6 , and the end of the driven support arm 7 is rotationally connected to a material receiving roller assembly 8 .

[0051] The above content is the basic scheme of the utility model, and its loading working principle is: the staff controls the cart through the handle 31 to push out the plastic film roll 9 that is stacked close to the whole (mostly stacked horizontally), selects the plastic film roll 9 that needs to be transported, and then adjusts the height of the adapter 5 (material receiving roller assembly 8) through the vertical linear drive module 4, and adjusts the horizontal direction of the material receiving roller assembly 8 through the horizontal drive device 6, so that the material receiving roller assembly 8 is aligned with the plastic film roll 9, and then pushes the cart forward to make the material receiving roller assembly 8 and insert the plastic film roll 9, and then pulls the cart backward, and then manually operates the material receiving roller assembly 8 (plastic film roll 9) to make the material receiving roller assembly 8 rotate relative to the driven support arm 7, so that the horizontal direction of the material receiving roller assembly 8 (plastic film roll 9) is switched to the vertical direction, so that the lower end of the plastic film roll 9 contacts the horizontal bottom plate 1 of the cart, and finally the staff can pull the cart to transfer the plastic film roll 9 to other places.

[0052] The working principle of the plastic film roll 9 unloading is opposite to the action of loading, which will not be described in detail here.

[0053] Compared with the prior art, the unique structural features and functions of the utility model are at least: 1. Through the coordinated operation of the vertical linear drive module 4 and the horizontal drive device 6, manual labor is replaced, and the function of mechanically and automatically inserting and placing the plastic film roll 9 can be realized; 2. Inserting and placing the plastic film roll 9 in the horizontal direction will not block the line of sight, thereby facilitating the staff to better adjust the position of the material receiving roller assembly 8 to more accurately insert the plastic film roll 9, greatly reducing the probability of damage to the plastic film roll 9; 3. The horizontal and vertical directions of the material receiving roller assembly 8 can be adjusted, so as to meet the use requirements of plastic film rolls 9 of different sizes and models.

[0054] It is worth mentioning that the roller body 81 described in the utility model is provided with a plurality of convex ribs 811. When designing, it is necessary to set the size of the roller body 81 to be slightly smaller than the size of the plug-in hole 91 on the plastic film roll 9, so as to facilitate the insertion of the roller body 81, and the plastic film roll 9 will not be squeezed in all directions during the insertion process, so as to protect the plastic film roll 9 from damage. At the same time, through the setting of the convex rib 811, it can contact the inner wall of the plug-in hole 91 on the plastic film roll 9, so that the roller body 81 and the plastic film roll 9 generate a local small-scale friction force to prevent the two from being loosened unnecessarily, especially to better ensure that the plastic film roll 9 will not easily fall off the roller body 81 when switching between the horizontal direction and the vertical direction. Furthermore, the roller body 81 and the convex rib 811 are made of rubber, which has a certain elasticity and softness, so as to better protect the plastic film roll 9.

[0055] In order to adapt to more sizes of plastic film rolls 9, a replaceable roller body 81 is preferably used, specifically: a threaded connection hole 85 is provided at the front end of the steering seat 82, and the roller bodies 81 are multiple and of different sizes, and the end of each roller body 81 has a threaded connection column 812 of the same size, and the threaded connection column 812 can be screwed into the threaded connection hole 85, so that the steering seat 82 is connected to any roller body 81. When replacing, the previous roller body 81 is screwed out of the threaded connection column 812, and then the subsequent roller body 81 required is screwed into the threaded connection column 812.

[0056] Embodiment 2

[0057] Based on the structure of the first embodiment, this embodiment is further optimized and improved to improve the degree of mechanization, specifically: Figure 1 The driven support arm 7 is in a "Z" shape, and the driven support arm 7 has at least a high point 71 and a low point 72, and the material receiving roller assembly 8 is located at the low point 72; a push-pull cylinder 73 is fixedly arranged at the high point 71, and the output end of the push-pull cylinder 73 forms a transmission match with the material receiving roller assembly 8.

[0058] By setting the push-pull cylinder 73, the receiving roller assembly 8 (plastic film roll 9) can be automatically switched between the horizontal direction and the vertical direction, replacing the manual switching method in the embodiment. In addition, the push-pull cylinder 73 is easier to control the movement stroke, making the switching action more accurate and in place.

[0059] A more perfect structural solution of this embodiment is: Figure 5The material receiving roller assembly 8 includes a steering seat 82, a roller body 81 fixed at the front end of the steering seat 82, and a steering joint 83 fixed at the upper end of the steering seat 82; the steering seat 82 is rotationally connected with the driven support arm 7 through a first rotating shaft 84; the output end of the push-pull cylinder 73 is rotationally connected with the steering joint 83 through a second rotating shaft 74, and at the same time, the output end of the push-pull cylinder 73 forms a transmission match with the steering joint 83.
