Description

Technical Field

[0001] This utility model relates to the technical field of anti-adhesion mechanisms, specifically an anti-adhesion mechanism for cutting plastic parts. Background Technology

[0002] The machining of plastics borrows from the plastics processing methods used for metals and wood to manufacture plastic products with very precise dimensions or in small quantities. It can also serve as an auxiliary process in molding, such as sawing extruded profiles. Because the properties of plastics differ from those of metals and wood, plastics have poor thermal conductivity, low coefficient of thermal expansion, and low modulus of elasticity. When the pressure applied by the fixture or tool is too great, it is prone to deformation. It is also prone to melting when heated during cutting and tends to stick to the tool.

[0003] Existing plastic parts cutting machines lack anti-sticking mechanisms, causing plastic parts to stick together after heat melting and gas cutting. This requires users to manually remove the stuck plastic parts, increasing processing time and reducing efficiency. Furthermore, manual removal of parts increases the risk of cuts from the cutting blade, reducing safety.

[0004] Therefore, an anti-sticking mechanism for cutting plastic parts is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-sticking mechanism for cutting plastic parts, including an outer shell. The inner sides of the outer shell are provided with a first groove and a second groove. A threaded rod is disposed inside the first groove, and the upper part of the threaded rod is connected to a rotating motor. A threaded sleeve block is fitted onto the threaded rod. A sliding rod is disposed inside the second groove, and a sliding sleeve block is fitted onto the sliding rod. A connecting horizontal plate is disposed between the threaded sleeve block and the sliding sleeve block. A mounting shell is disposed below the connecting horizontal plate. A hot-melt device is disposed inside the mounting shell, and the lower part of the hot-melt device is connected to a hot-melt cutting blade. An L-shaped wiping block is symmetrically disposed along the center position below the mounting shell.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0007] This utility model incorporates a rotating motor, a threaded rod, a threaded sleeve block, a sliding rod, and a sliding sleeve block. The rotating motor drives the threaded rod to rotate, which in turn moves the threaded sleeve block. The movement of the threaded sleeve block moves the connecting horizontal plate, thereby causing the hot melt cutting blade to extend out of the outer shell for easier cutting. The sliding sleeve block on the right side of the moving connecting horizontal plate moves on the sliding rod, improving the stability of the movement.

[0008] This invention features L-shaped wiping blocks symmetrically arranged on both sides of the lower part of the outer casing. The hot melt cutting blade is raised and lowered to contact the L-shaped wiping blocks, which facilitates the removal of adhesive substances from the cutting blade.

[0009] This utility model, by setting up an installation plate and installation nails, allows for easy maintenance of the hot melt device by removing the installation nails and removing the installation plate. Attached Figure Description

Detailed Implementation

[0014] 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.

[0015] As attached Figure 1 , 2 As shown, the present invention provides an anti-adhesion mechanism for cutting plastic parts, comprising an outer shell 1. The inner sides of the outer shell 1 are provided with a first groove 101 and a second groove 102. A threaded rod 5 is disposed inside the first groove 101, and the upper part of the threaded rod 5 is connected to a rotating motor 7. A threaded sleeve block 6 is fitted onto the threaded rod 5. A sliding rod 8 is disposed inside the second groove 102, and a sliding sleeve block 9 is fitted onto the sliding rod 8. A connecting horizontal plate 10 is disposed between the threaded sleeve block 6 and the sliding sleeve block 9. A mounting shell 11 is disposed below the connecting horizontal plate 10. A hot-melt device 13 is disposed inside the mounting shell 11, and the lower part of the hot-melt device 13 is connected to a hot-melt cutting blade 14. An L-shaped wiping block 15 is symmetrically disposed along the center position below the mounting shell 11.

[0016] Specifically, an mounting plate 2 is provided on the top of the outer shell 1, and mounting nails 201 are respectively provided on both sides of the mounting plate 2.

[0017] Specifically, a mounting plate 3 is provided on the outer front surface of the outer shell 1, and the mounting plate 3 is fixed to the outer shell 1 at its four corners by mounting nails 4.

[0018] Specifically, the mounting shell 11 is connected to the connecting cross plate 10 by fastening bolts 12.

[0019] Specifically, the rotating motor 7 and the hot-melt device 13 are respectively connected to an external control system.

[0020] Working principle: During use, the rotating motor 7 drives the threaded rod 5 to rotate, which in turn drives the threaded sleeve block 6 to move downward. The downward movement of the threaded sleeve block 6 drives the connecting horizontal plate 10 to move downward, which in turn drives the hot melt cutting blade 14 to extend downward out of the outer shell 1. When the connecting horizontal plate 10 moves, the sliding sleeve block 9 on the right side moves on the sliding rod 8, which improves the stability of the movement. Then the hot melt device 13 is started, and the hot melt cutting blade 14 is used for cutting. After the cutting is completed, the rotating motor 7 drives the threaded rod 5 to rotate, which in turn drives the threaded sleeve block 6 to move upward. The upward movement of the threaded sleeve block 6 drives the connecting horizontal plate 10 to move upward, which in turn moves the hot melt device 13 upward. The hot melt cutting blade 14 moves upward and contacts the L-shaped wiping block 15 to remove the adhesive on the cutting blade.

[0021] When maintenance is required, remove the mounting pin 4 and the mounting plate 3 to facilitate maintenance of the hot melt device 13.
