Description

Technical Field

[0001] The utility model relates to the field of plastic film cutting, in particular to a material dividing and cutting device for producing protective films of plastic products. Background Art

[0002] Plastic product protective film cutting equipment is a device for cutting plastic films. Plastic films are made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. They are used for packaging and as coating layers. Plastic packaging and plastic packaging products occupy an increasingly large share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields. These films need to be cut after production for further processing.

[0003] In the prior art, when traditionally cutting plastic film, a pressure plate is often used to press and limit the film, and then the film is cut by a cutter. However, since the plastic film is relatively thin and is easily adsorbed on a flat object, when the pressure plate is separated from the plastic film after the plastic film is cut, the pressure plate is likely to lift the free end of the plastic film, causing the plastic film to deviate and fold, which is not conducive to the subsequent cutting of the plastic film. At the same time, the plastic film is also likely to stick to the workbench after being pressed, making it inconvenient to cut the material. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a material dividing and cutting device for producing protective films for plastic products.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a windproof cabinet, a navigation plate is detachably connected to the inside of the windproof cabinet, baffles are fixedly connected to the upper surface of the navigation plate at both sides, one side surface of the baffle is fixedly connected to the first support plate, the lower end surface of the first support plate is fixedly connected to the upper surface of the navigation plate, the upper end of the first support plate is rotatably connected to a sheet pressing roller, the upper surface of the first support plate is rotatably connected to a supporting roller on the same side of the upper surface of the first support plate, the left end surface of the navigation plate is fixedly connected to a second support plate, the upper end of the second support plate is rotatably connected to a first bearing, and the outer surface of the first bearing is rotatably connected to a guide roller, the left side of the windproof cabinet is detachably connected to an upper baffle, and the left side of the windproof cabinet is detachably connected to a lower support plate. When traditional plastic film is sheared, it is often pressed by a pressing plate The plastic film is pressed to limit the position and then sheared by a cutter. However, since the plastic film is relatively thin and is easily adsorbed on a flat object, when the pressing plate and the plastic film are separated after the plastic film shearing is completed, the pressing plate is likely to lift up the free end of the plastic film, thereby causing the plastic film to deviate and fold, which is not conducive to the subsequent shearing of the plastic film. At the same time, the plastic film is also easily adhered to the workbench after being pressed, which is not convenient for material unloading. To address such problems, the rotational cooperation between the pressing roller and the supporting roller is adopted to achieve the effect of not having to press and limit the plastic film by the pressing plate, thereby avoiding the plastic film from being adsorbed on a flat object when the plastic film is relatively thin, thereby solving the problem of the free end of the plastic film being lifted up, avoiding the plastic film from deviating and folding, which is conducive to the subsequent shearing of the plastic film, reducing the adhesion of the plastic film to the workbench after being pressed, and making material unloading more convenient.

[0006] Preferably, the right end face of the navigation plate is detachably connected to a support platform, a knife groove is provided on the upper surface of the support platform, support frames are fixedly connected to both sides of the upper surface of the support platform, guide rods are fixedly connected to both sides of the upper surface of the support platform, a slider is slidably connected to the outer surface of the guide rod, a knife holder is fixedly connected to one side of the slider, and a knife is fixedly connected to the lower end face of the knife holder. The cutting tools of traditional plastic film cutting equipment are mostly fixedly set. In addition, the platform is provided, which makes the tool unable to be used for a long time, which easily causes the tool to wear and even cuts the film uncleanly, resulting in low cutting efficiency and a smaller scope of application. By setting a groove on the platform, the tool is protected when it is pressed down to extend the service time of the tool, so that the tool can cut the film more cleanly, the cutting efficiency is improved, and the scope of application is wider.

[0007] Preferably, a support block is fixedly connected to one end of the left side of the windproof cabinet, a fixing groove is provided at the front end of the support block, a first knob is threadedly connected to the support block, a spring is fixedly connected to the lower surface of the first knob, an outer nest is rotatably connected to the outer surface of the first knob, a second knob is threadedly connected to the front end of the outer nest, a connecting wire is fixedly connected to the tail end of the second knob, and a latch is fixedly connected to the other end of the connecting wire. Traditional film cutting devices use bolt connections, which leads to cumbersome disassembly and installation steps, resulting in a considerable amount of time spent in the processing process, requiring operators to make adjustments, and reducing processing efficiency. By adopting a latch structure, the latch is pulled out to rotate the support block, thereby making it more convenient for operators to install the film, reducing processing time and improving processing efficiency.

[0008] Preferably, the outer surface of the tableting roller is relatively rough. The rough surface of the roller can prevent the film from slipping during the processing, thereby affecting the processing efficiency.

[0009] Preferably, one end of the tool holder is fixedly connected with a bolt, and the tool holder is rotatably connected to a guide plate via the bolt, the lower end of the guide plate is rotatably connected to a connector, the guide plate is rotatably connected to a connecting plate via the connector, the lower end of the connecting plate is rotatably connected to an engine, and the lower end surface of the engine is fixedly connected with a bracket, and by adopting a connector structure and a bracket supporting the engine, reciprocating cutting of the tool on the tool holder is achieved.

[0010] Preferably, a fixing device is fixedly connected to the lower surface of the windproof cabinet, and is fixed to the ground through the fixing device, so that the device can be prevented from being offset during processing.

[0011] Beneficial Effects

[0012] 1. In the prior art, when traditionally cutting plastic film, a pressure plate is often used to press and limit the plastic film, and then a cutter is used to cut the plastic film. However, since the plastic film is relatively thin and is easily adsorbed on a flat object, when the pressure plate and the plastic film are separated after the plastic film is cut, the pressure plate is likely to lift up the free end of the plastic film, thereby causing the plastic film to deviate and fold, which is not conducive to the subsequent cutting of the plastic film. At the same time, the plastic film is also likely to adhere to the workbench after being pressed, which is not convenient for unloading. To address such problems, the rotational cooperation between the pressing roller and the supporting roller is adopted, so that the pressing plate does not need to be pressed and limited by the pressure plate, and the plastic film is prevented from being adsorbed on a flat object when the thickness is relatively thin, thereby solving the problem of lifting up the free end of the plastic film, avoiding the plastic film from deviating and folding, which is conducive to the subsequent cutting of the plastic film, reducing the adhesion of the plastic film to the workbench after being pressed, and making unloading more convenient.

[0013] 2. In the prior art, the cutting tools of traditional plastic film cutting equipment are mostly fixed. In addition, the platform makes it impossible to use the tool for a long time, which easily causes the tool to wear and tear, and even the film is not cut cleanly, resulting in low cutting efficiency and a small scope of application. To address such problems, the utility model adopts a platform to set up a groove, so that the tool is protected when it is pressed down to extend the use time of the tool, so that the tool can cut the film more cleanly, the cutting efficiency is improved, and the scope of application is wider.

[0014] 3. In the prior art, the traditional film cutting device is connected by bolts, which leads to complicated disassembly and installation steps, which takes a lot of time in the processing and requires the operator to make adjustments, thus reducing the processing efficiency. To address this problem, the utility model adopts a latch structure. By pulling out the latch, the support block can be rotated, so that the operator can install the film more conveniently, reduce the time in the processing process, and improve the processing efficiency.
