AI Technical Summary
Polystyrene foam boards are prone to displacement during the cutting process due to the pressure of the heating wire, resulting in damage to the ends. Especially when the cutting is completed, the board displacement seriously affects the quality of the cut.
An auxiliary device is designed, comprising a cutting table, a guide drive device, a cutting device, and a pressure device. The guide drive device controls the movement of the heating wire, and the pressure device applies rear pressure to the plate during the cutting process to keep the heating wire and the plate relatively fixed and prevent displacement.
It effectively prevents the board from shifting during the cutting process, ensuring the integrity of the board ends and the straightness of the cut, thus improving the cutting quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of polystyrene board production technology, and in particular to a cutting auxiliary device for polystyrene foam board production. Background Technology
[0002] Polystyrene board, also known as foam board or EPS board, is a white material made of expandable polystyrene beads containing volatile liquid foaming agents. After being pre-expanded by heating, the beads are formed in a mold. It has a micro-closed-cell structure and is widely used in building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicle and ship insulation, floor heating, decoration and carving, and many other applications.
[0003] When processing polystyrene sheets, the block-shaped foamed material needs to be cut according to the required sheet size. Generally, the cutting is done slowly using a heating wire. Because polystyrene sheets are very light, when they are cut into thin sheets, they will be squeezed by the heating wire, causing the sheets to shift to a certain extent. This is especially true when the ends of the sheets are cut off, which can easily cause the sheets to shift or even damage the ends. Therefore, it is necessary to apply auxiliary pressure during the cutting process to prevent the sheets from moving. Utility Model Content

[0023] like Figure 1-3 The cutting auxiliary device for polystyrene foam board production shown includes a cutting table 1, a guide drive device 2, a cutting device 3, and a pressure device 4. The guide drive device 2 is fixedly installed at both ends of the upper surface of the cutting table 1. The cutting device 3 is movably connected to the guide drive device 2. The pressure device 4 is movably installed at one end of the top of the cutting device 3. The cutting device 3 includes a gantry frame 31, a heating seat 32, a heating wire 33, a connecting plate 34, and a connecting shaft 35. The heating seat 32 is installed inside the gantry frame 31, the heating wire 33 is clamped inside the heating seat 32, and the connecting plate 34 is fixedly installed. On one side of the top of the gantry frame 31, the connecting shaft 35 is fixedly installed inside the connecting plate 34. The pressure device 4 includes a collar 41, a retaining shaft 42, a limiting rod 43, a locking knob 44, a sleeve 45, a mounting rod 46, and a pressure roller 47. The collar 41 is sleeved on the outside of the connecting shaft 35, the retaining shaft 42 is fixedly installed on the outside of the collar 41, the limiting rod 43 is fixedly installed on the outside of one end of the retaining shaft 42, the locking knob 44 is installed on the outside of the limiting rod 43, the sleeve 45 is sleeved on the outside of the retaining shaft 42, the mounting rod 46 is fixedly installed at the end of the sleeve 45, and the pressure roller 47 is movably connected to the mounting rod 46.
[0024] Specifically, the guide drive device 2 includes a support plate 21, a guide seat 22, a guide rod 23, a lead screw 24, and a motor 25. The support plate 21 is fixedly disposed on the upper surface end of the cutting table 1, the guide seat 22 is fixedly disposed on the inner bottom of the support plate 21, the guide rod 23 is fixedly disposed on the inner side of the support plate 21, the lead screw 24 is movably connected to the support plate 21, the motor 25 is installed on the outer side of the support plate 21, the bottom of the guide seat 22 is in contact with the upper surface of the cutting table 1, and one end of the lead screw 24 is connected to the output of the motor 25. The gantry 31 has a guide groove at its bottom that mates with the guide seat 22. The gantry 31 has a guide hole that mates with the guide rod 23 and a threaded hole that mates with the lead screw 24. One end of the limiting rod 43 passes through and extends to the outside of the sleeve 45. The surface of the sleeve 45 has a slot that mates with the limiting rod 43. The surface of the limiting rod 43 has a thread and is connected to the locking knob 44 by a thread. The surface of the sleeve 45 has a flat surface in the contact area between the locking knob 44 and the sleeve 45.
[0025] In this embodiment, the block of polystyrene foam to be cut is first placed on the upper surface of the cutting table 1. Then, according to the required cutting size, the heating wire 33 is installed in the connection end of the specific heating seat 32. The height of the pressure roller 47 is adjusted according to the height of the polystyrene foam block. The length of the retaining shaft 42 can be adjusted in the sleeve 45 by simply loosening the locking knob 44 on the surface of the limiting rod 43. After adjusting to the appropriate length, the locking knob 44 is tightened to lock the height of the pressure roller 47.
[0026] Furthermore, the motor 25 starts, driving the lead screw 24 to rotate, thereby causing the gantry 31, which is threadedly connected to the lead screw 24, to move slowly. The bottom of the gantry 31 is supported by the guide seat 22 and guided and supported by the guide rod 23 on the inner side of the support plate 21, thus moving stably and slowly, allowing the energized heating wire 33 to cut the block of polystyrene. As the gantry 31 moves, the pressure roller 47 acts on the top of the polystyrene block and slowly rotates and moves forward with the movement of the gantry 31, maintaining a certain distance from the cutting position of the heating wire 33 to avoid the pressure affecting the cutting effect of the heating wire 33. When the heating wire 33 is about to finish cutting, its pressure will cause the polystyrene board to deviate to a certain extent, resulting in an uneven cut at the end of the board and even affecting the size of the board. After the pressure is applied by the pressure roller 47, this situation can be avoided, thus ensuring the quality of the end of the board.
