Description

Technical Field

[0001] This utility model relates to the field of packaging material processing equipment technology, and in particular to a cut-resistant and dustproof film cutting frame. Background Technology

[0002] Dustproof films are widely used in industrial production and packaging of various products. They can effectively prevent dust, dirt, water droplets and other impurities from entering the product surface, protecting the product from damage or corrosion. Dustproof films have a certain degree of flexibility and wear resistance, which can prevent products from being scratched or worn during transportation and storage.

[0003] Traditional methods of cutting dustproof film often rely on simple blades. The blades of traditional cutting tools are exposed, which can easily cause operators to accidentally come into contact with them and get injured. At the same time, if operators use the blades to cut the dustproof film without any assistance, the cutting edge may deviate, resulting in incorrect cutting dimensions.

[0004] Therefore, to address the above issues, a cut-proof and dust-proof film cutting frame can be designed to provide effective protection, preventing operators from being cut by the sharp cutting blade during the cutting process, while ensuring the stability of the cutting blade during the cutting process. Utility Model Content

[0005] To overcome the problem that most dustproof film cutting methods often rely on simple blades, traditional cutting tools have exposed blades that are easy for operators to accidentally come into contact with and get injured. At the same time, when operators use the blade to cut the dustproof film without assistance, the cutting edge may deviate, resulting in incorrect cutting dimensions.

[0006] The technical solution of this utility model is as follows: a cut-resistant and dustproof film cutting frame, including an installation frame, a cutting blade, and a pressure assembly. The pressure assembly includes a spring, a pressure roller, and an installation crossbeam. An installation crossbeam is provided on the inner side of the installation frame. There are four installation crossbeams, divided into upper and lower groups. A sliding seat is provided between the installation crossbeams in the same group. A sliding block is provided on the inner side of the sliding seat. The sliding block is slidably connected to the sliding seat. A cutting blade is provided on the side of the sliding block near the installation crossbeam. The cutting blade is fixedly connected to the sliding block. A pressure roller is provided on one side of the installation crossbeam. The pressure roller is slidably connected to the installation crossbeam. A limit plate is provided on the side of the installation crossbeam away from the pressure roller. A spring is provided between the limit plate and the installation crossbeam. A shaft is provided on the top of the installation frame.

[0007] Preferably, a support frame is provided above the mounting frame, and a placement groove is provided on the inner side of the support frame.

[0008] Preferably, the bottom of the mounting frame is provided with a base, and diagonal braces are provided between the base and the mounting frame. Universal wheels are provided at the four corners of the bottom of the base.

[0009] Preferably, the sliding seat has a guide groove, the side of the sliding block away from the cutting blade is provided with a first force-bearing block, and support plates are provided between the mounting beams in the same group, with gaps left between the support plates.

[0010] Preferably, the pressure roller is provided with connecting seats at both ends, and a guide rod is provided on one side of the connecting seat. The guide rod is slidably connected to the mounting beam, and a bolt is provided at one end of the guide rod.

[0011] Preferably, a limit rod is provided on one side of the mounting beam, the limit rod is slidably connected to the limit plate, and a first limit groove is provided at one end of the limit rod.

[0012] Preferably, a limiting seat is provided on the side of the limiting plate away from the mounting beam. The limiting seat has a sliding hole, and a second limiting groove is provided on one side of the sliding hole. The diameter of the sliding hole is the same as that of the limiting rod, and the width of the second limiting groove is the same as that of the first limiting groove. A connecting block is provided between the two sets of limiting seats, and a second force-bearing block is provided on one side of the connecting block.

[0013] The beneficial effects of this utility model are:

[0014] The mounting frame is used to install and fix the mounting beam, shaft, and sliding seat. During cutting, the dustproof film in the shaft is pulled out to the required length, and then the sliding block in the sliding seat is pushed directly, which drives the cutting blade to cut the dustproof film. During this process, the spring provides thrust to the pressure roller, pressing the dustproof film tightly against the mounting beam to prevent it from moving around during cutting. The above process is simple and quick. The cutting blade travels in a straight line, ensuring accurate cutting dimensions and neat edges. At the same time, the operator does not need to come into direct contact with the cutting blade, greatly reducing the risk of the operator being cut. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a cut-resistant and dustproof film cutting frame, including a mounting frame 1, a cutting blade 6, and a pressure assembly. The pressure assembly includes a spring 8, a pressure roller 7, and a mounting beam 3. The mounting frame 1 has four mounting beams 3 arranged in upper and lower groups. A sliding seat 4 is provided between the mounting beams 3 in the same group. A sliding block 5 is provided inside the sliding seat 4 and is slidably connected to the sliding seat 4. A cutting blade 6 is provided on the side of the sliding block 5 closest to the mounting beam 3 and is fixedly connected to the sliding block 5. A pressure roller 7 is provided on one side of the mounting beam 3 and is slidably connected to the mounting beam 3. A limit plate 9 is provided on the side of the mounting beam 3 away from the pressure roller 7. A spring 8 is installed between the limiting plate 9 and the mounting beam 3, and a shaft 2 is installed above the mounting frame 1. The mounting frame 1 is used to install and fix the mounting beam 3, shaft 2 and sliding seat 4. During cutting, the dustproof film in the shaft 2 is pulled out to the required length, and then the sliding block 5 in the sliding seat 4 is pushed directly to drive the cutting blade 6 to cut the dustproof film. During this process, the spring 8 provides thrust to the pressure roller 7, pressing the dustproof film tightly against the mounting beam 3 to prevent the dustproof film from moving around during cutting. The above process is simple and quick. The cutting blade 6 travels in a straight line, making the cutting size accurate and the edges neat. At the same time, the operator does not need to directly contact the cutting blade 6, which greatly reduces the risk of the operator being cut.

[0022] Please see Figure 1In this embodiment, a support frame 201 is provided above the mounting frame 1, and a placement groove 202 is provided on the inner side of the support frame 201. A base 102 is provided at the bottom of the mounting frame 1, and a diagonal brace 101 is provided between the base 102 and the mounting frame 1. Universal wheels 103 are provided at the four corners of the bottom of the base 102. The placement groove 202 is used to guide the shaft 2 into the support frame 201. The base 102 and the diagonal brace 101 support the mounting frame 1, and the universal wheels 103 allow the device to move freely.

[0023] Please see Figure 2 In this embodiment, the sliding seat 4 is provided with a guide groove 401, and the sliding block 5 is provided with a first force-bearing block 501 on the side away from the cutting blade 6. Support plates 301 are provided between the mounting beams 3 in the same group, and gaps are left between the support plates 301. The guide groove 401 is used to guide the movement of the sliding block 5. The first force-bearing block 501 makes it easy for the operator to exert force to push the sliding block 5 to move. The spaced support plates 301 can support the dustproof film during cutting while hiding the cutting blade 6 in the support plates 301 to prevent injury to the operator.

[0024] Please see Figure 3 In this embodiment, the pressure roller 7 is provided with connecting seats 701 at both ends, and a guide rod 702 is provided on one side of the connecting seat 701. The guide rod 702 is slidably connected to the mounting beam 3, and a bolt 703 is provided at one end of the guide rod 702. The spring 8 pushes the limiting plate 9 away from the mounting beam 3, thereby driving the guide rod 702 and the connecting seat 701 to move, so that the pressure roller 7 and the mounting beam 3 are tightly fitted, pressing the dustproof film onto the surface of the mounting beam 3. The bolt 703 fixes the limiting plate 9 to the first limiting groove 902. At the same time, the rolling connection between the pressure roller 7 and the connecting seat 701 allows the operator to easily pull out the dustproof film roll for the next cut after the cutting is completed.

[0025] Please see Figure 4In this embodiment, a limiting rod 901 is provided on one side of the mounting beam 3. The limiting rod 901 is slidably connected to the limiting plate 9. One end of the limiting rod 901 has a first limiting groove 902. A limiting seat 905 is provided on the side of the limiting plate 9 away from the mounting beam 3. The limiting seat 905 has a sliding hole 906. A second limiting groove 907 is provided on one side of the sliding hole 906. The diameter of the sliding hole 906 is the same as that of the limiting rod 901, and the width of the second limiting groove 907 is the same as that of the first limiting groove 902. The diameters at 02 are consistent. A connecting block 903 is provided between the two sets of limiting seats 905. A second force-bearing block 904 is provided on one side of the connecting block 903. During cutting, the operator can grasp the second force-bearing block 904 to drive the limiting seat 905 to move laterally, so that the limiting rod 901 leaves the sliding hole 906 and the first limiting groove 902 and the second limiting groove 907 are engaged with each other, thereby connecting the mounting beam 3 and the limiting plate 9 into a whole, preventing the pressure roller 7 from moving during cutting.

[0026] In use, insert the dustproof film roll into the shaft 2 and place the shaft 2 into the support frame 201. Then, stretch the dustproof film to a suitable length, grasp the second force block 904 to drive the limit seat 905 to move laterally, causing the limit rod 901 to leave the sliding hole 906 and the first limit groove 902 and the second limit groove 907 to engage with each other, thereby connecting the mounting beam 3 and the limit plate 9 into a whole, preventing the pressure roller 7 from moving during cutting. During the process of stretching the dustproof film, the spring 8 pushes the limit plate 9 away from the mounting beam 3, thereby driving the guide rod 702 and the connecting seat 70 The movement of the pressure roller 7 and the mounting beam 3 causes them to fit tightly together, pressing the dustproof film onto the surface of the mounting beam 3. Then, the first force block 501 pushes the sliding block 5 to slide in the sliding seat 4, thereby driving the cutting blade 6 to move and cut the dustproof film. After cutting, the sliding connecting block 903 causes the limit rod 901 to return to the sliding hole 906 and pull out the dustproof film again. During this process, the cutting blade 6 is always hidden in the support plate 301, avoiding injury to the operator caused by the cutting blade 6. At the same time, the cutting blade 6 moves along the trajectory of the guide groove 401, ensuring the neatness of the cut surface.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
