Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of extruded board cutting equipment, and in particular to a heating wire clamping device for extruded board cutting. Background Technology
[0002] After initial heating and extrusion molding, extruded polystyrene (XPS) insulation materials need to be cut according to the dimensional requirements of the application site to meet usage requirements. Currently, XPS cutting commonly employs two methods: mechanical cutting with a cutting disc and thermodynamic heating wire cutting. Heating wire cutting, due to its high efficiency and precision, is widely used in XPS processing. However, traditional heating wire cutting devices suffer from problems such as unstable clamping and easy wear, affecting cutting quality and efficiency.
[0003] Utility model patent CN205852972U discloses a clamping device for cutting heating wires in extruded polystyrene (XPS) boards and the XPS board itself. This device, by incorporating springs and adjusting nuts at both ends of the clamping body, allows the heating wire to automatically adjust its tension according to the thickness of the XPS board during cutting, eliminating the need for manual adjustment. This method is fast and efficient, and the elastic buffering effect of the springs prevents damage to the heating wire during cutting. However, the length of the heating wire in this device is fixed, and only the tension can be adjusted. It cannot flexibly adjust the wire length according to the thickness of the XPS board. For thinner XPS boards, an excessively long heating wire can lead to inaccurate cutting, while for thicker XPS boards, an excessively short heating wire cannot effectively cut, limiting the device's applicability. Therefore, improvements are urgently needed. Utility Model Content
[0004] The purpose of this invention is to provide a clamping device for the heating wire of extruded polystyrene board cutting, which can not only adjust the tension of the heating wire, but also adjust the length of the heating wire. Therefore, it can not only greatly improve the cutting accuracy and efficiency, but also adapt to the cutting needs of extruded polystyrene boards of different thicknesses, making the device more versatile and practical, and effectively solving the limitations of existing devices.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A clamping device for cutting heating wire in extruded polystyrene board includes a base body respectively disposed at both ends of the heating wire and an adjusting rod for mounting the heating wire. The adjusting rod has an axial through hole at its center. The heating wire passes through one end of the axial through hole and exits from the other end of the axial through hole, and is fixedly connected to a slider sleeved on the adjusting rod and slidingly engaged with the adjusting rod. One side of the slider is threadedly connected to the adjusting screw hole on the base body by an adjusting bolt, and the other side of the slider is provided with a fixing mechanism for fixing the adjusting rod at different axial positions.
[0007] By adopting the above technical solution, when the tension of the heating wire needs to be adjusted, the adjusting bolt is rotated. The adjusting bolt drives the slider and the adjusting rod connected to the slider through the fixing mechanism to move axially synchronously, thereby tightening or loosening the heating wire to maintain a suitable tension. This avoids cutting errors caused by excessive tension or slack in the heating wire, ensuring cutting accuracy and efficiency. When the length of the heating wire needs to be adjusted, the fixing mechanism is first loosened, and then the adjusting bolt is rotated again to move the slider axially relative to the adjusting rod until the heating wire reaches the required length. Then, the adjusting rod and slider are fixed again through the fixing mechanism. Therefore, the length of the heating wire can be flexibly adjusted to meet the cutting needs of extruded boards of different thicknesses. The structure is simple and easy to operate, and the versatility and practicality of the device are greatly improved. It effectively solves the limitations of existing devices and significantly improves cutting quality and production efficiency.
[0008] A further feature of this invention is that the rod of the adjusting bolt passes through the slider and slides axially with the slider, the head of the adjusting bolt rests against the side wall of the slider, and the rod of the adjusting bolt is also fitted with a return spring, the two ends of the return spring being fixed to the side walls of the slider and the seat respectively.
[0009] By adopting the above technical solution, when the adjusting bolt rotates, it will move axially along the adjusting screw hole connected to it. During this process, the head of the adjusting bolt will squeeze the slider, so that the slider moves axially synchronously with the adjusting rod or slides relative to the adjusting rod, thereby realizing the tension adjustment or length adjustment of the heating wire. The return spring can provide a reverse elastic force to ensure that the adjustment process is smooth and prevent over-adjustment. On the other hand, it can also work with the bolt head to apply stable pressure to the slider, ensuring that the slider can always move synchronously with the adjusting bolt, and ensuring the reliability of the tension adjustment and length adjustment process.
[0010] A further feature of this invention is that the fixing mechanism includes a fixing screw hole on the slider and a plurality of positioning holes on the adjusting rod. The fixing screw hole is internally threaded with a fixing screw rod, which can be inserted into or removed from the positioning hole opposite to it by rotation.
[0011] By adopting the above technical solution, when the slider moves axially relative to the adjusting rod until its fixing screw hole is aligned with the different positioning holes on the adjusting rod, the fixing screw can be rotated to insert it into the corresponding positioning hole, thereby realizing the fixing operation of the slider at different positions on the adjusting rod. The fixing process is simple and convenient to operate.
[0012] A further feature of this invention is that: a boss is provided at the end of the adjusting rod away from the slider, and a compression spring is provided between the boss and the seat body, with the two ends of the compression spring abutting against the side wall of the boss and the seat body respectively.
[0013] By adopting the above technical solution, the compression spring is used to provide a certain support force for the adjusting rod. On the one hand, it can make the adjusting rod more stable during the synchronous axial movement with the slider. On the other hand, it can also provide a certain resistance when the slider slides relative to the adjusting rod, preventing the adjusting rod from sliding synchronously with the slider and causing adjustment failure, thus ensuring the accuracy and stability of the adjustment process. In addition, the design of the compression spring can also effectively absorb the vibration generated during the adjustment process, further extending the service life of the device and improving the overall working performance.
[0014] A further feature of this invention is that the slider is provided with a slot for fixing the heating wire, and a heating wire fixing screw hole is provided on one side of the slot. The heating wire fixing screw hole is internally threaded with a heating wire fixing screw for pressing and fixing the heating wire in the slot.
[0015] By adopting the above technical solution, after the end of the heating wire is inserted into the slot, the heating wire fixing bolt is rotated to make its end press tightly against the heating wire, ensuring that the heating wire is stable and immovable in the slot, thereby realizing the fixed connection between the end of the heating wire and the slider. The connection process is simple and easy to operate.
[0016] A further feature of this invention is that a roller is provided at one end of the adjusting rod near the slider, the roller is connected to a mounting base fixed at the end of the adjusting rod via a rotating shaft, and the heating wire passes through the other end of the axial through hole, wraps around the roller, and is fixedly connected to the slider.
[0017] By adopting the above technical solution, the roller can effectively reduce the friction between the heating wire and the adjusting rod, improve the smoothness of the heating wire movement, ensure that the heating wire is not easily worn during the adjustment process, and extend its service life.
[0018] A further feature of this invention is that the roller is made of a high-temperature resistant insulating material.
[0019] By adopting the above technical solution, the roller is made of high-temperature resistant insulating material, which ensures that it can maintain good performance even in high-temperature environments, avoiding deformation or damage to the roller due to the high temperature of the heating wire, thus affecting the adjustment accuracy and safety. At the same time, the insulating material effectively prevents current leakage, ensuring safe use.
[0020] A further feature of this invention is that a high-temperature resistant insulating sleeve is provided inside the axial through hole of the adjusting rod, and one axial side of the sleeve is cut open.
[0021] By adopting the above technical solution, the high-temperature resistant insulating sleeve can effectively prevent the adjusting rod from directly contacting the heating wire, avoiding wear and short circuits caused by high temperature. On the other hand, it can also buffer the heating wire, further reducing vibration during the adjustment process and improving the overall stability and safety of the device. The sleeve is cut open on one side of the axis to facilitate the insertion and fixation of the heating wire. The ingenious cut design ensures both convenient installation and the tightness and protective effect of the sleeve, comprehensively improving the reliability and service life of the device.
[0022] The beneficial effects of this utility model are:
[0023] 1. When the heating wire tension needs to be adjusted, rotate the adjusting bolt. The adjusting bolt drives the slider and the adjusting rod connected to the slider via the fixing mechanism to move axially synchronously, thereby tightening or loosening the heating wire to maintain appropriate tension and avoid cutting errors caused by excessive tension or slack. This ensures cutting accuracy and efficiency. When the length of the heating wire needs to be adjusted, first loosen the fixing mechanism, then rotate the adjusting bolt again to move the slider axially relative to the adjusting rod until the heating wire reaches the required length. Then, fix the adjusting rod and slider again via the fixing mechanism. This achieves flexible adjustment of the heating wire length, adapting to the cutting needs of extruded boards of different thicknesses. It is not only simple in structure and easy to operate, but also greatly improves the versatility and practicality of the device, effectively solving the limitations of existing devices and significantly improving cutting quality and production efficiency.
[0024] 2. In this utility model, the return spring can provide a reverse elastic force to ensure a smooth adjustment process and prevent over-adjustment. On the other hand, it can also work with the bolt head to apply stable pressure to the slider, ensuring that the slider can always move synchronously with the adjusting bolt, thus ensuring the reliability of the tension adjustment and length adjustment processes.
[0025] 3. In this utility model, the compression spring is used to provide a certain supporting force to the adjusting rod. On the one hand, it can make the adjusting rod more stable during the synchronous axial movement with the slider. On the other hand, it can also provide a certain resistance when the slider slides relative to the adjusting rod, preventing the adjusting rod from sliding synchronously with the slider and causing adjustment failure, thus ensuring the accuracy and stability of the adjustment process. In addition, the design of the compression spring can also effectively absorb the vibration generated during the adjustment process, further extending the service life of the device and improving the overall working performance.
[0026] 4. The roller in this utility model can effectively reduce the friction between the heating wire and the adjusting rod, improve the smoothness of the heating wire movement, ensure that the heating wire is not easily worn during the adjustment process, and extend its service life.
[0027] 5. In this utility model, the high-temperature resistant insulating sleeve effectively prevents direct contact between the adjusting rod and the heating wire, avoiding wear and short circuits caused by high temperatures. It also buffers the heating wire, further reducing vibration during adjustment and improving the overall stability and safety of the device. The sleeve is cut open on one axial side to facilitate the insertion and fixation of the heating wire. This ingenious cut design ensures both convenient installation and a tight fit and protective effect, comprehensively improving the reliability and service life of the device.

[0036] Furthermore, the fixing mechanism 7 includes a fixing screw hole 71 provided on the slider 5 and a plurality of positioning holes 72 provided on the adjusting rod 3. The fixing screw hole 71 is internally threaded with a fixing screw 73, and the fixing screw 73 can be inserted into or removed from the positioning hole 72 opposite to it by rotation.
[0037] Furthermore, the end of the adjusting rod 3 away from the slider 5 is provided with a boss 9, and a compression spring 10 is provided between the boss 9 and the seat 2. The two ends of the compression spring 10 abut against the boss 9 and the side wall of the seat 2, respectively.
[0038] Furthermore, the slider 5 is provided with a slot 11 for fixing the heating wire 1, and a heating wire fixing screw hole 12 is provided on one side of the slot 11.
