Description

Technical Field

[0001] This utility model relates to the field of thermal insulation strip processing, and in particular to a cutting device for producing shear-resistant thermal insulation strips. Background Technology

[0002] Thermal insulation strips have important applications in many fields, especially in industries such as building doors and windows. They can effectively prevent heat conduction and improve energy-saving performance. As a thermal insulation material with good shear resistance, shear-resistant thermal insulation strips often need to be cut and processed according to specific size requirements before actual use to adapt to different installation scenarios and product specifications.

[0003] A search revealed Chinese Patent Publication No. CN217434400U, which discloses a fixed-length cutting device for producing nylon thermal insulation strips. The device includes a worktable with a transverse movement mechanism inside. The movable end of the transverse movement mechanism extends to the top of the worktable and is equipped with a cutting device. A nylon thermal insulation strip to be cut is positioned directly below the cutting device. Limiting plates are provided on both sides of the nylon thermal insulation strip, allowing it to slide laterally between the two limiting plates. The limiting plates are located at the top edge of the worktable. The device keeps the nylon thermal insulation strip in a transverse state, activates the transverse movement mechanism to move the cutting device laterally, and cuts the nylon thermal insulation strip to the required length. The distance between the cutting device and the clamping device is adjusted. This device solves the problems of low efficiency, high workload, and low cutting accuracy associated with traditional manual cutting of nylon thermal insulation strips.

[0004] Although the above-mentioned device can cut nylon thermal insulation strips to a fixed length, in actual operation, since the two sets of clamping devices are on both sides of the worktable, although they can fix both sides, the middle is prone to bulging during the cutting process, which affects the accuracy of subsequent cutting. Secondly, in the subsequent trimming of thermal insulation strips of different sizes, although the clamping device on one side can be used, the other side needs to be pressed manually, which poses certain safety hazards. Therefore, a cutting device for the production of shear-resistant thermal insulation strips is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a cutting device for producing shear-resistant thermal insulation strips, including a cutting table 1. A movable frame 2 is provided in the middle of the cutting table 1. The movable frame 2 is controlled to move by existing driving equipment, which is a conventional technical means and will not be described in detail here. A hydraulic rod 3 is provided through the inner wall of the movable frame 2. The hydraulic rod 3 is existing technology and can control the vertical movement of the support block 16 to complete the cutting process of the thermal insulation strip. The extension end of the hydraulic rod 3 is fixedly connected to the support block 16. The bottom end of the support block 16 has a cutting blade. The cutting blade can be replaced by existing bolts, which is existing technology and will not be described in detail here. A fixing plate 4 is fixedly connected to the side wall of the support block 16. A connecting frame 6 is elastically connected to the inner wall of the fixing plate 4 through a torsion spring 5. A roller 7 is rotatably connected to the inner side wall of the connecting frame 6. The surface of the roller 7... The surface is made of soft material, which allows the roller 7 to contact the surface of the heat insulation strip without causing damage. The top of the cutting table 1 is slidably connected to an adjustment frame 8. The adjustment frame 8 mainly supports and connects the entire electric telescopic rod 11. The inner wall of the adjustment frame 8 is provided with a limit mechanism. The electric telescopic rod 11 is installed through the inner wall of the adjustment frame 8. The electric telescopic rod 11 is a mechanical device that can realize telescopic movement. The bottom end of the electric telescopic rod 11 is fixedly connected to a pressure plate 12. The pressure plate 12 can position the heat insulation strip to ensure that it will not deviate during the cutting process. The top of the cutting table 1 is provided with a slot 13. The slot 13 has a horizontal opening and a vertical opening. The horizontal opening allows the card block 10 to move left and right, and the vertical opening allows the card block 10 to be inserted to limit the entire adjustment frame 8. The inner wall of the cutting table 1 is provided with a collection component.

[0032] The limiting mechanism includes a locking block 10, which is slidably connected to the inner wall of the adjusting frame 8. The adjusting frame 8 has a corresponding slot for the locking block 10, which allows the locking block 10 to move vertically along the slot. The outer wall of the locking block 10 is elastically connected to the adjusting frame 8 through a return spring 9.

[0033] Reference Figure 1 and Figure 5 The collection component includes a storage box 15, which is detachably installed on the inner wall of the cutting table 1. The storage box 15 can collect impurities during the cutting of the heat insulation strip, reducing the amount of impurities remaining on the cutting table 1 and affecting the subsequent cutting effect. A filter screen 14 is provided at the top of the cutting table 1. There are two sets of filters screen 14, which are symmetrically arranged on both sides, so as not to affect the normal placement of the heat insulation strip.

[0034] Reference Figures 2-4The outer wall of the locking block 10 is fixedly connected to one end of the return spring 9. When the locking block 10 moves forward, it will compress the return spring 9. When resetting, the elastic force of the return spring 9 will drive the locking block 10 to reset. The other end of the return spring 9 is fixedly connected to the inner wall of the front end of the adjusting frame 8. The locking block 10 is inserted into the inner wall of the slot 13. The inner wall of the fixing plate 4 is fixedly connected to one end of the torsion spring 5. When the connecting frame 6 rotates, it will compress the torsion spring 5. When resetting, the elastic force of the torsion spring 5 will drive the connecting frame 6 to reset. The other end of the torsion spring 5 is fixedly connected to the end of the connecting frame 6. The connecting frame 6 is rotatably connected to the inner wall of the fixing plate 4.

[0035] Working principle: When the heat insulation strip needs to be cut, simply place it on the cutting table 1 between the filter screens 14. Then, activate the hydraulic rod 3 to move the support block 16 downwards. The roller 7 will first contact the heat insulation strip. Since the connecting frame 6 is hinged, when the roller 7 contacts it, it will cause the connecting frame 6 to rotate counterclockwise along the inner wall of the fixing plate 4, which will compress the torsion spring 5. The reverse elastic force of the torsion spring 5 will make the connecting frame 6, along with the roller 7, continue to contact the heat insulation strip, forming a smoothing operation to avoid the middle bulge affecting the cutting accuracy. While smoothing, the electric telescopic rods 11 on both sides will move the pressure plate 12 downwards to press down on the heat insulation strips on both sides, ensuring the cutting is smooth. For stability, when the support block 16 moves upward, the reverse elastic force of the torsion spring 5 will bring the connecting frame 6 and roller 7 back to their initial state, ready for the next cut. If multiple heat insulation strips of different lengths need to be trimmed, the locking block 10 can be moved forward by hand and the return spring 9 can be compressed to separate the vertical opening of the locking block 10 and the slot 13, allowing the locking block 10 to move along the horizontal opening to adjust the position of the individual adjusting frame 8. When the designated position is reached, the locking block 10 can be released and the elastic force of the return spring 9 will bring the locking block 10 back to its original position, allowing the locking block 10 to be inserted into the vertical slot of the slot 13. This ensures the positioning of heat insulation strips of different lengths and reduces the safety hazards of hand pressing during cutting.

[0036] After cutting, staff can clean the impurities on the cutting table 1 into the filter screen 14, and then collect them in the storage box 15.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
