Description

Technical Field

[0001] This invention relates to the field of material cutting technology, and more particularly to a hot wire rotary cutting fixture for EPE cylinders. Background Technology

[0002] EPE (expanded polyethylene) foam, a lightweight, flexible, and shock-absorbing new type of environmentally friendly packaging material, has been widely used in packaging protection and structural filling scenarios in fields such as electronic components, precision instruments, furniture and appliances, and logistics transportation, thanks to its good impact resistance, corrosion resistance, and recyclability. In actual production, EPE products often need to be processed into specific shapes according to application requirements to adapt to the packaging and filling requirements of different scenarios.

[0003] Chinese patent CN215749539U discloses a hot wire cutting machine. This machine achieves the forward and backward movement of the hot wire by moving the nut on the lead screw, and the up and down movement of the hot wire by moving the slider on the slide rail, thus enabling cutting at different angles and positions. However, the hot wire of this machine moves along a preset trajectory and cannot perform surface machining on the workpiece. Furthermore, the machine is driven entirely by a motor, requiring considerable time for adjustments when modifying small quantities or individual workpieces, resulting in low efficiency.

[0004] Therefore, it is necessary to develop a hot wire rotary cutting fixture for EPE cylinders to solve the above problems. Utility Model Content

[0010] Furthermore, a fixing through hole is provided at the end of the crank, and the fixing through holes of the crank are arranged opposite to each other, with the two ends of the resistance wire respectively fixed in the fixing through hole.

[0011] Furthermore, the resistance wire is parallel to the optical axis.

[0012] Furthermore, the optical axis is fitted with a pair of conductive rings, which maintain the electrical connection between the resistance wire and the external power supply.

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.

[0024] Please refer to Figures 1 to 3 This utility model is a hot wire rotary cutting fixture for EPE columns, which includes a fixed frame 1 and a cutting assembly 2 mounted on the fixed frame 1.

[0025] Please refer to Figures 1 to 2 The fixed frame 1 includes a base plate 11, a pair of side plates 12 surrounding the base plate 11, and a back plate 13. The base plate 11 is horizontal. The pair of side plates 12 are installed on both sides of the base plate 11, with their bottoms fixedly connected to the base plate 11 and their tops extending vertically upwards. The bottom of the back plate 13 is also fixedly connected to the base plate 11, and its top extends vertically upwards. At the same time, the two sides of the back plate 13 are fixedly connected to the pair of side plates 12. The base plate 11, side plates 12, and back plate 13 constitute a frame structure.

[0026] Preferably, a support plate 14 is installed on the outer surface of the side plate 12. One side of the support plate 14 is fixedly connected to the side plate 12, and the other side extends outward to support the cutting assembly 2.

[0027] Please refer to Figure 1 and Figure 3 The cutting assembly 2 includes a drive unit 21, an optical shaft 22 connected to the drive unit 21, a pair of cranks 23 sleeved on the optical shaft 22, and a resistance wire 24 connected to the pair of cranks 23. In this embodiment, the drive unit 21 is a DC motor, mounted on a support plate 14. A coupling 25 is installed at the output end of the drive unit 21, and one end of the optical shaft 22 is connected to the drive unit 21 through the coupling 25.

[0028] A through hole is provided in the upper half of a pair of side plates 12, and a bearing seat 26 is installed in the through hole, through which the optical axis 22 passes.

[0029] One end of crank 23 has a larger diameter and the other end has a smaller diameter. The larger diameter end is fitted onto the optical axis 22, and the other end extends perpendicular to the optical axis 22. Specifically, the spacing between the cranks 23 can be changed according to requirements.

[0030] Furthermore, a fixing through hole 231 is provided at the end of the crank 23. The fixing through holes 231 of the crank 23 are arranged opposite to each other, and the two ends of the resistance wire 24 are respectively fixed in the fixing through hole 231, which are parallel to the optical axis 22.

[0031] Furthermore, the optical axis 22 is fitted with a pair of conductive rings 27. The conductive rings 27 are existing technology and will not be explained in detail. The pair of conductive rings 27 are used to maintain the electrical connection between the resistance wire 24 and the external power supply.

[0033] This utility model discloses a rotary cutting fixture for EPE cylinders using a heating wire. In use, the resistance wire 24 is in the initial position, with its height greater than the optical axis 22. The workpiece is placed on the base plate 11. When the power is turned on, current flows through the conductive ring, continuously heating the resistance wire 24. Rotating the handwheel 28 causes the resistance wire 24 to move in a circular motion around the optical axis 22, its trajectory forming a continuous cylindrical surface. When the high-temperature resistance wire 24 passes through the workpiece along this trajectory, the surface of the contacted EPE material is melted, thus cutting an arched cylinder of EPE material. Alternatively, the drive unit 21 can be used to rotate the optical axis 22, allowing the resistance wire 24 to automatically cut the workpiece. After cutting, the resistance wire 24 returns to the initial position, and a new workpiece is replaced.

[0034] This utility model is a rotary cutting fixture for EPE cylinders using an electric heating wire. It features a simple structure and is easy to adjust and maintain. The fixed frame consists of a base plate, side plates, and a back plate. The cutting assembly includes simplified components such as a drive unit, optical shaft, crank, and resistance wire, which are directly connected. It is easy to adjust, and the crank spacing can be modified to suit different processing needs. The drive mode can be switched between manual and automatic. The resistance wire and core components are easy to disassemble and maintain. Through its simple structure and flexible adjustment design, it can efficiently cut EPE cylinders.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
