Description
Technical Field
[0001] This utility model relates to the field of foam board cutting technology, specifically a cutting device for EPS foam board production. Background Technology
[0002] The core function of cutting equipment used in foam board production is to precisely and efficiently customize the size and shape of foam boards. Firstly, it can cut large pieces of foam board into specific lengths, widths, and thicknesses to meet the dimensional requirements of various applications such as building insulation and packaging materials. Secondly, through CNC or automation technology, it can cut complex shapes such as irregular shapes and curves, increasing the added value of products, such as for making handicrafts and models.
[0003] The utility model disclosed in CN214520481U is a foam board dust removal and cutting device. Its structure includes a workbench, slit, support, cutting machine, adjusting and fixing rod, ventilation duct, moving track, air intake, exhaust fan, cutter, belt, etc. The cutter of this utility model can move on the track with the motor, so the foam board to be cut can be automatically cut simply by placing it on the workbench, which greatly reduces the workload. In addition, the utility model has a dust removal effect by setting an exhaust fan, making the working environment cleaner and more hygienic.
[0004] The aforementioned utility model uses a sawtooth-shaped rotary wheel to drive the cutting section and the exhaust fan section to move along a track. Since both the cutting section and the central controller section are large in size and have complex structures, driving these two parts via the sawtooth-shaped rotary wheel requires a significant amount of electrical energy and bears a large load, making them prone to severe wear during operation. Furthermore, the exhaust fan section lacks a stable support and constraint structure, making it difficult to ensure it doesn't sway during movement. Additionally, since the cutting section can only reciprocate in one direction, when cutting foam boards of different sizes, manual adjustment of the cut size is required, which is cumbersome and prone to uneven cuts due to misalignment during placement. Therefore, to address these problems, a cutting device for EPS foam board production is proposed. Utility Model Content
[0005] To address the technical problems of complex structure, rapid wear and tear of transmission components leading to unusable operation, difficulty in ensuring the stability of the moving structure, and the need for manual control of cutting dimensions which can easily result in skewed cuts in the comparative technologies, this utility model provides a cutting device for EPS foam board production.
[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:
[0007] A cutting device for EPS foam board production includes a cutting table with a cutting component mounting frame installed in its center. Adjustable guide rails located on the upper and lower sides of the cutting table are mounted on the cutting component mounting frame. A sliding adjustment seat is slidably disposed within the adjustable guide rails. An electrothermal cutting wire has both ends electrically connected to the sliding adjustment seat, and its axis is perpendicular to the plane containing the upper surface of the cutting table. The cutting table has several arrayed mounting slots, each housing several rotating rolling support members. An alignment baffle is installed on one side of the cutting table. The sliding adjustment seat includes a sliding block slidably connected to the adjustable guide rails, which is electrically connected to the electrothermal cutting wire via an electrical connector mounted thereon.
[0008] In one possible implementation, the adjustable guide rail includes a guide rail curved plate, which encloses a limiting groove, and a guide rod is fixedly disposed in the guide rail curved plate.
[0009] In one possible implementation, the sliding block is slidably sleeved on the guide rod, and its outer wall is slidably fitted with the guide rail curved plate; the guide rail curved plate is provided with a mating groove, and a locking screw that slides in the mating groove is fixedly provided on the sliding block, and a locking wheel is threadedly connected to the locking screw.
[0010] In one possible implementation, the electrical connector includes a receiving end and a plug end, wherein the receiving end is fixedly disposed at the bottom of the sliding block, and the sliding block is equipped with a cable interface electrically connected to the receiving end, and the plug end is disposed at the end of the electrothermal cutting wire and electrically connected thereto.
[0011] In one possible implementation, a retaining ring is fixedly provided on the plug-in end, and an anti-disengagement cover that engages with the retaining ring is slidably sleeved on the outside of the plug-in end, with the upper part of the anti-disengagement cover threadedly connected to the receiving end.
[0012] In one possible implementation, the rolling support includes a central shaft, on which a rotatably connected roller is sleeved, and the horizontal plane at the highest point of the roller cross-section coincides with the plane at the upper end of the cutting table.
[0013] In one possible implementation, the cutting table has an adjustment groove that is in the same direction as the sliding block, and the electrothermal cutting wire passes through the adjustment groove without contacting it.
[0014] In one possible implementation, the cutting component mounting bracket includes an L-shaped upper support frame and a lower suspension frame, wherein the L-shaped upper support frame is fixedly connected to the upper end face of the adjustable guide rail, and the lower suspension frame is connected to both ends of the adjustable guide rail.
[0015] In summary, this utility model has the following beneficial technical effects:
[0016] This equipment cuts foam boards using an electrothermal cutting wire perpendicular to the cutting table. During operation, the foam board is aligned with one side and against the alignment baffle, then pushed towards the electrothermal cutting wire to complete the cut. This method ensures a smooth cut. Furthermore, the cutting table has several rolling support components, which significantly reduce friction between the foam board and the cutting table, allowing the operator to smoothly move the foam board to complete the cutting. In summary, the above solution is simple in design, easy to operate, and less prone to component damage during use, ensuring stable operation over a long period.
[0017] When it is necessary to change the cutting size of the foam board, the size adjustment can be completed simply by operating the sliding adjustment seat. Specifically, the sliding block is moved in the distance adjustment guide rail to change the distance between the electrothermal cutting wire and the alignment baffle, thereby adjusting the cutting size. There is no need for workers to manually control it based on experience, making the operation very convenient.
[0018] Furthermore, since the electrothermal cutting wire is detachably connected to the sliding block via an electrical connector, the replacement and installation of the electrothermal cutting wire is very convenient, allowing for quick replacement when the electrothermal cutting wire is damaged or cannot ensure normal working performance.

Roller. Detailed Implementation
[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:
[0027] like Figure 1 As shown in the figure, this embodiment provides a cutting device for EPS foam board production, including a cutting table 1, a cutting component mounting frame 2 installed in the middle, and adjustable guide rails 3 located on the upper and lower sides of the cutting table 1 installed on the cutting component mounting frame 2; a sliding adjustment seat 4, which is slidably disposed in the adjustable guide rail 3; an electrothermal cutting wire 5, whose two ends are electrically connected to the sliding adjustment seat 4, and whose axis is perpendicular to the plane of the upper end surface of the cutting table 1; in addition, an alignment baffle 6 is installed on one side of the cutting table 1.
[0028] Based on the above technical solution, the foam board is cut by the electric heating cutting wire 5 set perpendicular to the cutting table 1. During operation, the foam board is aligned with one side and attached to the alignment baffle 6, and then the foam board is pushed towards the electric heating cutting wire 5 to complete the cutting of the foam board. This method can ensure the flatness of the cut. Moreover, the above solution is simple in structure, convenient to operate, and is not prone to component damage during use, and can maintain the stable operation of the equipment for a long time.
[0029] Because the surface of foam board is usually not very smooth, there is usually a lot of friction between it and the cutting table 1, which may make it difficult for the operator to move the foam board. Therefore, to reduce the friction between the foam board and the cutting table 1, the cutting table 1 has several arrayed mounting slots 12, in which several rotating rolling support members 7 are installed. Each support includes a central shaft 71, and a rotatably connected roller 72 is fitted around it. The horizontal plane of the highest point of the roller 72's cross-section coincides with the plane of the upper surface of the cutting table 1. Figure 1 , Figure 5 As shown, the opening of the mounting groove 12 can significantly reduce the contact area between the foam board and the cutting table 1, thereby significantly reducing the friction between the two. The roller 72 rolls in contact with the bottom surface of the foam board, which provides support while hardly hindering the sliding of the foam board, allowing the operator to smoothly push the foam board to complete the cutting work.
[0030] If the equipment is to have an adjustable cutting size, the distance between the electric heating cutting wire 5 and the alignment baffle 6 needs to be changed, thereby adjusting the size of the cut foam board.
[0031] Based on the above requirements, the sliding adjustment seat 4 includes a sliding block 41 slidably connected to the adjusting guide rail 3, which is electrically connected to the electrothermal cutting wire 5 via an electrical connector 42 mounted on it. Meanwhile, the adjusting guide rail 3 includes a guide rail curved plate 31, which forms a limiting groove, and a guide rod 32 is fixedly installed in the guide rail curved plate 31. Figure 2 - Figure 4 As shown.
[0032] Specifically, the sliding block 41 is slidably sleeved on the guide rod 32, and its outer wall is slidably attached to the guide rail curved plate 31. The guide rail curved plate 31 has a mating groove 33. The sliding block 41 is fixedly provided with a locking screw 43 that slides in the mating groove 33. The locking screw 43 is threadedly connected to a locking wheel 44. Based on the above structural scheme, the position of the sliding block 41 can be adjusted by sliding along the guide rod 32, thereby driving the electric heating cutting wire 5 connected to it to move and adjust its position, so as to adjust the cutting size. When it is necessary to fix the position of the electric heating cutting wire 5, tighten the locking wheel 44 to make it fit against the surface of the guide rail curved plate 31, and fix the position of the sliding block 41 by friction, thereby fixing the position of the electric heating cutting wire 5.
[0033] As a cooperating measure for adjusting the position of the electrothermal cutting wire 5, the cutting table 1 is provided with an adjustment groove 11 in the same direction as the sliding block 41. The electrothermal cutting wire 5 passes through the adjustment groove 11 without contacting it. Figure 1 As shown, the above-mentioned structural form provides the necessary structural basis for the movement of the electrothermal cutting wire 5.
[0034] As a consumable component, the electrothermal cutting wire 5 may need to be replaced frequently during use. Therefore, it needs to be easy to disassemble. Thus, it is detachably connected to the sliding block 41 via the electrical connector 42.
[0035] For electrical connector 42, such as Figure 4As shown, it includes a receiving end 421 and a plug-in end 422. The receiving end 421 is fixedly disposed at the bottom of the sliding block 41, and a cable interface 45 electrically connected to the receiving end 421 is installed on the sliding block 41. The plug-in end 422 is disposed at the end of the electrothermal cutting wire 5 and electrically connected to it. The above-mentioned plug-in connection method facilitates the quick assembly and disassembly of the electrothermal cutting wire 5. At the same time, in order to prevent the plug-in end 422 from coming out of the receiving end 421 due to tension during use, A retaining ring 423 is fixedly provided on the plug-in end 422, and an anti-disengagement cover 424 that engages with the retaining ring 423 is slidably sleeved on the outside of the plug-in end 422. The upper part of the anti-disengagement cover 424 is threadedly connected to the receiving end 421. Based on the above scheme, the plug-in end 422 can be fixedly connected to the bottom of the receiving end 421 by the engagement of the anti-disengagement cover 424 and the retaining ring 423, preventing the plug-in end 422 from separating from the receiving end 421 during use, which would cause the electrothermal cutting wire 5 to malfunction.
[0036] like Figure 2 As shown, the cutting component mounting bracket 2 includes an L-shaped upper support bracket 21 and a lower suspension bracket 22. The L-shaped upper support bracket 21 is fixedly connected to the upper end face of the adjustable guide rail 3, and the lower suspension bracket 22 is connected to both ends of the adjustable guide rail 3. Through the above technical solution, the adjustable guide rail 3 at the upper and lower positions can be installed at the designated positions so that it can function stably.
[0037] The working principle and usage process of this utility model:
[0038] The foam board is cut using an electrothermal cutting wire 5 that is perpendicular to the cutting table 1. During operation, the foam board is aligned with one side and attached to the alignment baffle 6. Then, the foam board is pushed towards the electrothermal cutting wire 5 to complete the cut. This method ensures the flatness of the cut. When it is necessary to change the cutting size of the foam board, the size can be adjusted simply by operating the sliding adjustment seat 4. Specifically, the sliding block 41 is slid in the distance adjustment guide rail 3 to change the distance between the electrothermal cutting wire 5 and the alignment baffle 6, thereby adjusting the cutting size. No manual control by the worker based on experience is required, making the operation very convenient.
[0039] Because the cutting table 1 is equipped with several rolling support parts 7, the friction between the foam board and the cutting table 1 can be greatly reduced, allowing the operator to smoothly push the foam board to complete the cutting work.
[0040] Furthermore, since the electrothermal cutting wire 5 is detachably connected to the sliding block 41 via the electrical connector 42, the replacement and installation of the electrothermal cutting wire 5 are very convenient, and it can be quickly replaced when the electrothermal cutting wire 5 is damaged or cannot ensure normal working performance.
[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
