Description
Technical Field
[0001] This utility model belongs to the field of heat-insulating reflective film cutting technology, specifically, it relates to a device that facilitates cutting heat-insulating reflective film. Background Technology
[0002] Heat-insulating reflective film has been widely used in building decoration, car window tinting, and home appliance protection due to its excellent heat insulation performance and reflective effect. In actual use, the heat-insulating reflective film needs to be precisely cut according to different application scenarios and size requirements.
[0003] During the use of heat-insulating reflective film, it is often necessary to cut the roll of heat-insulating reflective film into multiple narrow reflective strips and then lay them on the required equipment or location. However, the existing heat-insulating reflective film is mostly cut manually by measuring and cutting, which is troublesome, complicated and inefficient, and prone to cutting deviations.
[0004] In view of this, this utility model is proposed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a device that facilitates cutting heat-insulating reflective film, thus solving the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0007] A device for easily cutting heat-insulating reflective film includes:
[0008] A support base, with a processing base fixed on its upper side, and a winding roller rotatably fitted on the upper side of the processing base, the winding roller being located on one side of the processing base;
[0009] The lifting frame is installed on both sides of the upper part of the support base. The lifting frame is equipped with a moving part. The output end of the moving part is equipped with a moving block. L-shaped plates are fixed on both sides of the moving block. One end of the L-shaped plate is elastically fitted with a pressing wheel. A snap-fit part is installed on the lower side of the moving block. A cutting blade is installed on the snap-fit part.
[0010] The pressing assembly includes multiple torsion springs installed on both sides of the bottom of the lifting frame. Each torsion spring is equipped with an elastic telescopic rod, and one end of the elastic telescopic rod is equipped with a damping wheel.
[0011] Optionally, the L-shaped plate is provided with a groove, and a first spring is installed between one side of the inner wall of the groove and the extrusion wheel.
[0012] Optionally, the snap-fit component includes a mounting frame fixed to the lower side of the movable block, a fixing cylinder fixed inside the mounting frame, fixing blocks elastically fitted on opposite sides of the fixing cylinder, fixing grooves on opposite sides of the cutting blade, and fixing blocks engaging with the fixing grooves; through holes on opposite sides of the fixing cylinder, a second spring fixed to one end of the fixing block and one side of the inner wall of the mounting frame, and the fixing block slidingly fitting within the through hole; arc-shaped surfaces at the ends of the two fixing blocks, the two arc-shaped surfaces being arranged in opposite directions; arc-shaped guide grooves on opposite sides of the cutting blade, extending to the upper surface of the cutting blade, and the arc-shaped guide grooves engaging with the fixing blocks.
[0013] Optionally, the moving part includes a lead screw, which is rotatably engaged within the lifting frame. The moving block is provided with a threaded groove, and the moving block is threadedly engaged with the lead screw through the threaded groove.
[0014] Optionally, electric push rods are fixed on both sides of the upper part of the support base, and the output ends of the two electric push rods are respectively connected to the lower ends of the lifting frame.
[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0016] With the damping rollers, the heat-insulating reflective film to be cut is flattened as the lifting frame moves, improving the flatness of the reflective film during cutting. This not only reduces the need for manual flattening of the heat-insulating reflective film but also facilitates subsequent cutting. The extrusion rollers position the heat-insulating reflective film before cutting. As the extrusion rollers rotate, the moving parts drive the cutting blade, and the extrusion rollers, along with the cutting blade, extrude and position the reflective film to be cut, improving cutting stability and reducing errors. The snap-fit mechanism facilitates the replacement of the cutting blade and enables maintenance and upkeep of frequently used blades.

Detailed Implementation
[0033] The present invention will now be described in further detail with reference to the accompanying drawings.
[0034] Please see Figure 1-6 As shown, this embodiment provides a device for cutting heat-insulating reflective film, including a support base 1, a processing base 101 fixed on the upper side of the support base 1, a winding roller 102 rotatably engaged on the upper side of the processing base 101, and the winding roller 102 located on one side of the processing base 101.
[0035] Lifting frame 2 is installed on both sides of the upper part of support base 1. A moving part 3 is installed inside the lifting frame 2. A moving block 301 is installed at the output end of the moving part 3. An L-shaped plate 302 is fixed on both sides of the moving block 301. A pressing wheel 303 is elastically fitted at one end of the L-shaped plate 302. A snap-fit part 4 is installed on the lower side of the moving block 301. A cutting knife 5 is installed on the snap-fit part 4.
[0036] Pressing assembly 6 includes multiple torsion springs 601 installed on both sides of the bottom of the lifting frame 2. Elastic telescopic rods 602 are installed on the torsion springs 601, and a damping wheel 603 is installed at one end of the elastic telescopic rods 602.
[0037] When it is necessary to cut the heat-insulating reflective film, first rotate the winding roller 102 to spread the reflective film on the winding roller 102 to a suitable cutting distance, and then lay the reflective film flat on the upper surface of the processing seat 101.
[0038] Next, the lifting frame 2 is driven to move towards the reflective film located on the processing seat 101. As the lifting frame 2 moves, the damping wheel 603 on the lifting frame 2 will first contact the heat-insulating reflective film. As the lifting frame 2 moves, the elastic telescopic rod 602 will rotate around the torsion spring 601 and retract as the damping wheel 603 contacts the heat-insulating reflective film. This allows the multiple damping wheels 603 and elastic telescopic rod 602 on both sides of the lifting frame 2 to spread the heat-insulating reflective film flat like human hands. This allows the heat-insulating reflective film to be flattened by itself before cutting, which not only facilitates the subsequent cutting by the cutting blade 5, but also reduces the step of manually flattening the heat-insulating reflective film before cutting.
[0039] After the damping wheel 603 and the elastic telescopic rod 602 flatten the reflective film, as the lifting frame 2 moves, the lifting frame 2 will drive the extrusion wheel 303, which is elastically fitted on the L-shaped plate 302, to press the heat-insulating reflective film. During the pressing process, because the extrusion wheel 303 is elastically fitted on one end of the L-shaped plate 302, the extrusion wheel 303 will squeeze the L-shaped plate 302 to shrink it until the cutting blade 5 and the reflective film 5 come into contact with each other. At this time, it is only necessary to start the moving part 3 to drive the cutting blade 5 to cut the fixed heat-insulating reflective film.
[0040] After cutting, simply restart the lifting frame 2 to reset the cutting blade 5, damping wheel 603 and extrusion wheel 303. As the lifting frame 2 resets, the damping wheel 603, due to the elastic force of the torsion spring 601, will drive the elastic telescopic rod 602 and extrusion wheel 303 to rotate and return to their initial positions (on the side closer to the lifting frame 2) to facilitate the next cutting of the heat insulation reflective film.
[0041] With the damping wheel 603 provided, as the lifting frame 2 moves, the heat-insulating and reflective film about to be cut can be flattened, improving the flatness of the heat-insulating and reflective film during cutting. This not only reduces the steps of manually flattening the heat-insulating and reflective film but also facilitates the subsequent cutting of the heat-insulating and reflective film. With the pressing wheel 303 provided, before the heat-insulating and reflective film is cut, the heat-insulating and reflective film can be positioned. When the pressing wheel 303 rotates itself, as the moving part 3 drives the cutting knife 5 during movement, the pressing wheel 303 can press and position the heat-insulating and reflective film about to be cut as the cutting knife 5 moves. While improving the stability of the heat-insulating and reflective film cutting, it also reduces the errors existing during cutting. With the clamping part 4 provided, it is convenient to replace the cutting knife 5 and facilitates the maintenance and upkeep of the frequently used cutting knife 5.
[0042] A chute 304 is provided inside the L-shaped plate 302 of this embodiment. A first spring 305 is installed between one side of the inner wall of the chute 304 and the pressing wheel 303. With the first spring 305 provided, when the pressing wheel 303 presses the reflective film, the first spring 305 will contract into the chute 304. Thus, by means of the elastic force of the first spring 305 itself after being compressed, the heat-insulating and reflective film can be continuously pressed, improving the stability and cutting accuracy of the heat-insulating and reflective film during cutting.
[0043] The snap-fit component 4 in this embodiment includes a mounting frame 401, which is fixed to the lower side of the moving block 301. A fixing cylinder 402 is fixed inside the mounting frame 401. Fixing blocks 403 are elastically fitted on opposite sides of the fixing cylinder 402. Fixing grooves 404 are provided on opposite sides of the cutting blade 5, and the fixing blocks 403 cooperate with the fixing grooves 404. Through holes are provided on opposite sides of the fixing cylinder 402 in this embodiment. A second spring 405 is fixed to one end of the fixing block 403 and one side of the inner wall of the mounting frame 401. The fixing block 403 is slidably fitted in the through hole. The ends of the two fixing blocks 403 in this embodiment are provided with arc-shaped surfaces, and the two arc-shaped surfaces are arranged in opposite directions. Arc-shaped guide grooves 501 are provided on opposite sides of the cutting blade 5 in this embodiment. The arc-shaped guide grooves 501 extend to the upper surface of the cutting blade 5 and cooperate with the fixing blocks 403. When it is necessary to install the cutting blade 5, simply align the two arc-shaped guide grooves 501 of the cutting blade 5 with the two fixing blocks 402, and move the cutting blade 5 upward so that the fixing blocks 402 move to the bottom of the arc-shaped guide grooves 501. Since the bottom of the arc-shaped guide grooves 501 and the fixing grooves 404 are on the same horizontal plane, simply rotate the cutting blade 5. With the arc-shaped surface at the end of the fixing block 403, the fixing block 403 can be moved during the rotation of the cutting blade 5. While the fixing block 403 is moving, it will squeeze the second spring 405. Then rotate the cutting blade 5. When the fixing groove 404 on the cutting blade 5 is aligned with the position of the fixing block 403, the fixing block 403 will be inserted into the fixing groove 404 under the elastic force of the second spring 405, thus facilitating the installation of the cutting blade 5.
[0044] With the arc-shaped surface at the end of the fixing block 403, when the cutting blade 5 needs to be disassembled, because the arc-shaped surfaces at the end of the fixing block 403 are set in opposite directions, when the cutting blade 5 rotates in the same direction of the two arc-shaped surfaces, the fixing block 403 will press the second spring 405 under the setting of the arc-shaped surface, which makes it easier for the fixing block 403 to disengage from the fixing groove 404, making the disassembly of the cutting blade 5 more convenient and quick, so as to facilitate the replacement and maintenance of the cutting blade 5 after long-term use.
[0045] In this embodiment, the movable component 3 includes a lead screw 306, which is rotatably fitted within the lifting frame 2. A movable block 301 has a threaded groove and is threadedly fitted onto the lead screw 306 through the threaded groove. Specifically, a guide rod is fixed inside the lifting frame 2, and a guide groove is provided on the movable block 301, which is slidably fitted onto the guide rod through the guide groove. A motor is fixed to one side of the lifting frame 2, and the output end of the motor passes through the side wall of the lifting frame 2 and connects to the lead screw 306. Under the forward and reverse drive of the motor, the forward and reverse rotation of the lead screw 306 can be controlled. Therefore, under the limiting guidance of the guide rod, the movable block 301 moves towards both ends of the lead screw 306 as it rotates forward and reverse, facilitating the control of the movement of the cutting blade 5 on the movable block 301, enabling the cutting blade 5 to stably cut the heat-insulating reflective film.
[0046] In this embodiment, electric push rods 103 are fixed on both sides of the upper part of the support base 1. The output ends of the two electric push rods 103 are respectively connected to the lower ends of the lifting frame 2. The electric push rods 103 can control the up and down movement of the lifting frame 2, and can not only control the pressing rollers 303 and damping rollers 603 on the lifting frame 2 to flatten and position the heat insulation reflective film, but also control the contact state between the cutting blade 5 and the heat insulation reflective film, so as to facilitate the subsequent cutting of the heat insulation reflective film.
[0047] In this embodiment, a support frame is installed on the upper side of the support base 1, and a cylinder is fixed on the upper side of the support frame. A movable plate is installed at the output end of the cylinder through the support frame. A pressing plate is elastically fitted on the side of the movable plate facing the support base 1. Through the setting of the pressing plate, the pressing plate on the lower side of the movable plate can be driven by the cylinder to press one end of the heat insulation reflective film. Before cutting, the heat insulation reflective film can be initially positioned by the pressing plate, so that the heat insulation reflective film will not shift during the subsequent further cutting process.
[0048] It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.
