Description

Technical Field

[0001] This utility model relates to the field of plastic cup cutting device, and more particularly to a plastic cup cutting device. Background Technology

[0002] Plastic cups are a common household item, typically made of plastic materials such as polystyrene (PS), polypropylene (PP), and polyethylene terephthalate (PET). They are lightweight, not easily broken, low in cost, and easy to process and mold. Plastic cups come in various shapes, including cylindrical and conical, and different capacities to meet diverse usage needs.

[0003] In the blow molding production of plastic cups, continuous film is used to assist in the forming of the cup body. After blow molding, the cup body and the film are connected. This connected state hinders the subsequent packaging process, and packaging machinery has difficulty operating the connected film cup body, making it impossible to achieve independent packaging of plastic cups. If the film is not cut, the connected cup body and film will affect the normal use and appearance of the product, and will also fail to meet the market demand for individual plastic cup products. Therefore, it is necessary to cut the plastic cup to separate the cup body from the film, ensuring that the product can smoothly enter the subsequent stages.

[0004] In related technologies, there are many problems with film cutting devices for plastic cups. For example, during the film cutting process, the two sides of the cutting point lack a clamping effect, which causes the film to sink in and become difficult to cut and separate from the plastic cup. At the same time, the position of the film may shift after cutting, affecting other processes.

[0005] Therefore, it is necessary to provide a plastic cup cutting device to solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic diagram of a preferred embodiment of a plastic cup cutting device provided by this utility model; Figure 2 for Figure 1 A structural schematic diagram of the rear view of the frame section shown; Figure 3 for Figure 1 A structural schematic diagram of the right view of the frame section shown; Figure 4 for Figure 2 The schematic diagram of the top view of the abutment plate shown shows a plastic cup film cutting device, including: a frame 1, and a film cutting assembly 2 provided on the inner side of the frame 1;

[0023] The film cutting assembly 2 includes a sliding rod 21 that slides up and down on the top of the frame 1. A lower pressure plate 22 is fixedly installed on the periphery of the sliding rod 21 and on the inner side of the frame 1. A mounting plate 23 is fixedly installed at the bottom of the sliding rod 21. A cutter 24 is detachably installed at the bottom of the mounting plate 23.

[0024] When the output end of the hydraulic rod 28 extends, it can drive the lower pressure plate 22 to move downward. When the lower pressure plate 22 moves downward, it will drive the mounting plate 23 and the cutter 24 to move downward, so that the cutter 24 cooperates with the abutment plate 29 to cut the film.

[0025] Two guide rods 25 are provided on the top left and right sides of the lower pressure plate 22, which can slide up and down. The bottom ends of the two guide rods 25 pass through the top of the lower pressure plate 22 and extend to its bottom. A pressing plate 26 is fixedly provided at the bottom ends of the two guide rods 25.

[0026] The bottom of the pressing plate 26 is lower than the bottom of the cutter 24. When the hydraulic rod 28 extends and retracts downward, the abutment plate 29 below the pressing plate 26 first abuts against the top of the film and presses it down. At this time, the hydraulic rod 28 continues to extend and retract downward, causing the lower pressing plate 22 to slide downward on the circumferential side of the guide rod 25, so that the cutter 24 passes through the film to cut it. By setting the abutment plate 29, the film on the front and back sides can be fixed before the cutter 24 cuts, avoiding the problems of misalignment and incomplete cutting during cutting.

[0027] A fixing spring 27 is provided on the top of the pressing plate 26 and on the periphery of the two guide rods 25 respectively. The top of the two fixing springs 27 are fixedly connected to the bottom of the lower pressing plate 22.

[0028] A hydraulic rod 28 is provided at the top of the frame 1. The telescopic end of the bottom of the hydraulic rod 28 passes through the top of the frame 1 and extends to its inner side. The telescopic end of the bottom of the hydraulic rod 28 is fixedly connected to the top of the lower pressure plate 22.

[0029] A detachable abutment plate 29 is provided on the bottom of the front of the pressing plate 26. The bottom of the abutment plate 29 has an opening 3 for the cutter 24 to pass through. Rubber pads are provided on the bottom of the abutment plate 29 and on both the front and rear sides of the opening 3.

[0030] By using the detachable abutment plate 29, different abutment plates 29 can be replaced to change the different passages 3 when applied to different cutters 24.

[0031] The bottom of the frame 1 is provided with a fixing plate 4, and the inner side of the fixing plate 4 is provided with mounting holes 5.

[0032] The frame 1 can be directly fixed in the required position using the fixing plate 4 and mounting holes 5. For example, it can be fixed after the plastic cup blow molding process to separate and cut the plastic cup.

[0033] The working principle of the plastic cup cutting device provided by this utility model is as follows:

[0034] Step 1: When in use, the frame 1 can be directly fixed in the required position through the fixing plate 4 and the mounting hole 5. When the plastic cup film to be cut passes the bottom of the cutter 24, the output end of the hydraulic rod 28 is extended, which drives the lower pressure plate 22 to move downward. When the lower pressure plate 22 moves downward, it will drive the mounting plate 23 and the cutter 24 to move downward, so that the cutter 24 cooperates with the abutment plate 29 to cut the film.

[0035] Step 2: Since the bottom of the pressing plate 26 is lower than the bottom of the cutter 24, when the hydraulic rod 28 extends and retracts downward, the abutment plate 29 below the pressing plate 26 first abuts against the top of the film and presses it down. At this time, the hydraulic rod 28 continues to extend and retract downward, causing the lower pressing plate 22 to slide downward on the circumferential side of the guide rod 25, so that the cutter 24 passes through the film to cut it. By setting the abutment plate 29, the film on the front and back sides can be fixed before the cutter 24 cuts, avoiding the problems of misalignment and incomplete cutting during cutting.

[0036] Step 3: Depending on actual needs, different cutters 24 and abutment plates 29 can be disassembled and replaced to better suit the needs of cutting plastic cups.

[0037] Compared with related technologies, the plastic cup cutting device provided by this utility model has the following advantages:

[0038] As the hydraulic rod 28 extends and retracts downwards, the abutment plate 29 below the pressing plate 26 first abuts against the top of the film and presses it down. At this time, the hydraulic rod 28 continues to extend and retract downwards, causing the lower pressing plate 22 to slide downwards on the circumferential side of the guide rod 25, so that the abutment plate 29 stops while the cutter 24 passes through the film to cut it. Through the pressing effect of the abutment plate 29, the film on the front and back sides can be fixed before the cutter 24 cuts, avoiding the problems of misalignment and incomplete cutting during cutting.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
