Description

Technical Field

[0001] This utility model belongs to the field of hot cutting machines, and specifically relates to a semi-automatic hot cutting machine. Background Technology

[0002] Currently, excess heat shrink tubing on manufactured products is typically trimmed manually using a utility knife and simple tooling. However, manual operation makes it difficult to ensure that the cutting position and angle are completely consistent each time, easily leading to inconsistent product dimensions and affecting subsequent assembly and use.

[0003] Meanwhile, during manual cutting, uneven operating force and angle can easily leave scratches on the material surface, affecting the appearance and performance of the product; and due to inaccurate positioning, the cutting line may deviate from the predetermined position during the cutting process, resulting in material waste.

[0004] Therefore, there is an urgent need to design a new type of device to solve the above problems. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a semi-automatic hot cutting machine. By setting up a support mechanism and a top positioning mechanism, the limit can be adjusted, which improves the compatibility of heat shrink tubing cutting. At the same time, it is equipped with separate cutters in four directions (up, down, left, and right) to prevent product scratches. All cutter components can be heated to improve efficiency through hot cutting.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a semi-automatic hot-cutting machine, including a placement rack, a placement plate, a support mechanism, a top positioning mechanism, a set of transverse hot-cutting mechanisms, and a longitudinal hot-cutting mechanism. The placement plate is mounted on the placement rack; the support mechanism is mounted on the placement plate; the top positioning mechanism is arranged opposite to the support mechanism for product placement and positioning; the transverse hot-cutting mechanism is located on both sides of the support mechanism for transverse hot-cutting of the heat shrink tubing wrapped around the product; the longitudinal hot-cutting mechanism is located in the middle of the placement rack for longitudinal hot-cutting of the heat shrink tubing wrapped around the product. The simultaneous provision of transverse and longitudinal hot-cutting mechanisms, combined with the hot-cutting method, prevents product scratches and improves efficiency and yield.

[0007] Furthermore, the placement mechanism includes two sets of roller placement assemblies and a guide assembly; the two sets of roller placement assemblies are respectively located on both sides of the transverse hot cutting mechanism; the guide assembly is located on the side away from the top positioning mechanism and between the roller placement assemblies. The roller placement assemblies provide support for the placement of the product, and the guide assembly ensures that the product can be smoothly placed into the working area for cutting operations.

[0008] Furthermore, the roller support assembly includes a support stabilizing plate, a support plate, a set of support connecting columns, and support rollers; the support stabilizing plate is disposed on the placement plate; the support plate is disposed on the support stabilizing plate via the support connecting columns; and the support rollers are disposed on the support plate. The support stabilizing plate ensures the stability of product placement; the support rollers provide a convenient pushing method for product placement, allowing the product to be pushed into the work area after one end is placed on the support rollers, reducing the workload of manual product placement.

[0009] Furthermore, the guiding assembly includes a scale holder, a reversible screw, a set of first guide rods, a knob, a set of guide sliders, and two sets of guide posts.

The transverse cutter head heating block is located at the output end of the transverse hot-cutting cylinder and connected to one end of the slide rod. The transverse cutter head is located beside the transverse cutter head heating block. The transverse hot-cutting cylinder drives the transverse cutter head heating block and the transverse cutter head to move laterally, and the slide rod, in conjunction with the transverse hot-cutting guide sliders, guides the lateral movement, ensuring the accuracy of the cutting. The transverse cutter head heating block heats the transverse cutter head, ensuring the realization of transverse hot cutting and improving cutting efficiency.

[0012] Furthermore, the longitudinal hot cutting mechanism includes a longitudinal hot cutting placement frame, an upper cutter head drive cylinder, an upper cutter head connecting plate, an upper cutter head heating block, an upper cutter head, a lower cutter head drive cylinder, a lower cutter head heating block, and a lower cutter head; the longitudinal hot cutting placement frame is mounted on the placement plate and located between the support mechanism and the top positioning mechanism; the upper cutter head drive cylinder is mounted on the longitudinal hot cutting placement frame; the upper cutter head connecting plate is located at the output end of the upper cutter head drive cylinder and is guided by the column of the longitudinal hot cutting placement frame; the upper cutter head heating block and the upper cutter head are both located on the lower surface of the upper cutter head connecting plate, and the upper cutter head is located beside the upper cutter head heating block; the lower cutter head drive cylinder is located on the lower surface of the placement plate, and its output end faces the upper cutter head heating block; the lower cutter head heating block is located at the output end of the lower cutter head drive cylinder; the lower cutter head is located beside the lower cutter head heating block and is on the same plane as the upper cutter head.
