Description

Technical Field

[0001] This invention relates to the field of film cutting equipment technology, specifically to a flexible PTC heating film cutting device for heating plate production. Background Technology

[0002] PTC stands for Positive Temperature Coefficient, generally referring to semiconductor materials or components with a large positive temperature coefficient. Usually, when we mention PTC, we mean a positive temperature coefficient thermistor, or simply PTC thermistor. A PTC thermistor is a typical temperature-sensitive semiconductor resistor; above a certain temperature (Curie temperature), its resistance increases abruptly with increasing temperature. A PTC (Positive Temperature Coefficient) heating film is a heating element made using a positive temperature coefficient material. The positive temperature coefficient means that as the temperature increases, the resistance also increases, thus stabilizing heating. PTC heating films are commonly used in electric heaters, car seat heaters, and space heaters. They have self-regulating temperature characteristics; when the temperature reaches a certain level, the resistance increases sharply, slowing down the heating rate and effectively preventing overheating. This technology helps improve the safety and stability of the equipment.

[0003] Because pressure-cut film cutting machines use blades to cut the film from top to bottom, they can only cut one sheet at a time, resulting in low cutting efficiency. Bevel-cut film cutting machines can cut multiple sheets, but like the old-fashioned pressure-cutting machines, when multiple layers are stacked, the top sheet is subjected to downward pressure and cutting force, and its own elasticity causes the top sheet to deform. This results in the upper sheet having a slightly larger area than the bottom sheet, affecting subsequent processing and use. Summary of the Invention

[0004] The problem this invention aims to solve is that when PTC films are stacked together and cut, the film at the top center position will be stretched and deformed from the cut.

The top of the housing is provided with connecting rods on both sides.

[0007] Preferably, both the drive wheel and the auxiliary wheel are equipped with a chain belt, and several limiting screws pass through the front of the chain belt. Cutting blades are inserted into the surface of the chain belt, and the cutting blades are slightly spaced apart from each other. The front of the cutting blade is provided with a threaded hole, which is adapted to the limiting screws.

[0008] Preferably, a number of cleaning blocks are equidistantly arranged on the top of the inner wall of the housing, a motor is provided on one side of the front of the housing, the output shaft of the motor passes through the housing and extends into the interior of the housing, and the back of the motor is fixedly connected to the front of the power wheel.

[0009] Preferably, the top of the housing is provided with an air duct, and the front and rear sides of the bottom of the air duct are provided with air outlets. A fan is provided at the top of the air duct, and the air force generated by the fan will be discharged outward from the air outlet through the air duct.

[0010] Preferably, the top of the fan is provided with a first bevel gear set, which can control the rotation of the fan. The front of the first bevel gear set is provided with a universal joint, the bottom of the universal joint is provided with a rotating shaft, and a bracket is provided on the rotating shaft. The back of the bracket is fixedly connected to the front of the housing.

[0011] Preferably, the bottom of the rotating shaft is provided with a second bevel gear set, the back of the second bevel gear set penetrates through the housing and extends into the interior of the housing, and the back of the second bevel gear set is fixedly connected to the front of the auxiliary wheel.

[0012] Preferably, the control structure includes a connecting plate, a fixed plate, a movable plate, a rotating seat, an eccentric wheel, an adjusting block, a connecting rod, a linkage block, and a slide rail. A motor is provided on the top of the top plate, a drive wheel is provided on one side of the motor, and a rotating seat is provided on one side of the top of the top plate. The rotating seat and the drive wheel mesh with each other.

[0013] Preferably, an eccentric wheel is provided on one side of the rotating seat, an adjusting block is provided at the bottom of one side of the eccentric wheel, a connecting rod is provided at the bottom of the adjusting block, and a fixing screw passes through the front of the adjusting block.

[0014] Preferably, the control cabinet has a fixed plate on one side, a connecting plate on one side of the fixed plate, a slide rail on one side of the front of the connecting plate, and a movable plate on the front of the slide rail.

[0016] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0017] (1) A cutting structure is provided on one side of the control cabinet. The cutting structure can form a moving cutting through the cooperation between the cutting blade and the chain, avoiding the traditional pressing cutting method. When the diaphragms are stacked together for cutting, the cut of the middle and upper layers of the diaphragms will not be deformed, so that the upper and lower diaphragms are cut evenly. The cutting blade is installed on the chain by plugging. The blade is thin. When it becomes dull or damaged after long-term use, the damaged blade can be directly removed and replaced without affecting other blades. The operation is simple and convenient. Just loosen the limit screw. The split replacement can minimize the cost of replacing the blade after it is damaged. In addition to the drive wheel inside the housing, it can also be used for cutting. In addition to controlling the chain belt for movement and cutting, it can also drive the auxiliary wheel to rotate. The auxiliary wheel can drive the fan to rotate through the cooperation between the first bevel gear and the second bevel gear set. The air force generated by the fan will be discharged outward from the air outlet through the air duct. The discharged air will form wind pressure on both sides of the cutting blade. In this way, the cutting blade can press down on the diaphragm on both sides when cutting and lifting, so as to prevent the diaphragm from shifting and affecting the operation when the blade is inserted or lifted. The inside of the outer shell is also equipped with a cleaning block. The cleaning block can grind the cutting blade and clean and scrape off the dirt and other residues on the blade. The grinding can keep the cutting blade sharp and achieve better cutting results.

[0018] (2) The top of the control cabinet is equipped with a control structure. The control structure can drive the linkage block to move downward to cut the diaphragm through the cooperation between the eccentric wheel and the movable plate. Compared with the linkage type cutting structure, the eccentric wheel type is simpler and more effective, and has a shorter stroke and consumes less mechanical energy. The back of the movable plate is equipped with a slide rail, which can limit the movement of the movable plate so that it can only move vertically up and down. The eccentric wheel is also equipped with an adjustment block and a connecting rod. The length of the connecting rod can also be adjusted by loosening the fixing screw on the adjustment block. In this way, the cutting stroke can be adjusted according to the stacked diaphragms of different thicknesses. The adjustment method is simple and convenient and will not take up too much operation time. Attached Figure Description

[0035] The cutting structure 5 includes an air duct 501, a first bevel gear set 502, a universal joint 503, a bracket 504, a rotating shaft 505, a second bevel gear set 506, a connecting rod 507, a motor 508, a housing 509, an air outlet 510, a chain belt 511, a cutting blade 512, a fan 513, an auxiliary wheel 514, a cleaning block 515, a limit screw 516, and a drive wheel 517. The bottom of the control structure 3 is provided with a housing 509, and the inside of the housing 509 is provided with a drive wheel 517 and an auxiliary wheel 514. The top of the housing 509 is provided with connecting rods 507 on both sides.

[0036] Both the drive wheel 517 and the auxiliary wheel 514 are equipped with a chain belt 511. Several limit screws 516 pass through the front of the chain belt 511. Cutting blades 512 are inserted into the surface of the chain belt 511. The cutting blades 512 are slightly spaced apart from each other. The front of the cutting blade 512 has a threaded hole that matches the limit screws 516. The cutting structure 5 can form a moving cutting by cooperating with the cutting blades 512 and the chain belt 511, avoiding the traditional pressure cutting method. When the diaphragms are stacked together for cutting, the cut of the middle and upper layers of the diaphragms will not be deformed, and the upper and lower diaphragms will be cut evenly. The cutting blades 512 are installed on the chain belt by insertion. The blades are thin. When they become dull or damaged after long-term use, the damaged blades can be directly removed and replaced without affecting the other blades. The operation is simple and convenient. Just loosen the limit screws.

[0037] A number of cleaning blocks 515 are equidistantly arranged on the top of the inner wall of the housing 509. A motor 508 is provided on one side of the front of the housing 509. The output shaft of the motor 508 passes through the housing 509 and extends into the interior of the housing 509. The back of the motor 508 is fixedly connected to the front of the power wheel 517.

The back of the second bevel gear set 506 penetrates the housing 509 and extends into the interior of the housing 509. The back of the second bevel gear set 506 is fixedly connected to the front of the auxiliary wheel 514. The auxiliary wheel 514 can drive the fan 513 to rotate through the cooperation between the first bevel gear 502 and the second bevel gear set 506. The wind generated by the fan 513 will be discharged outward from the air outlet 510 through the air duct 501. The discharged wind will form wind pressure on both sides of the cutting blade 512. In this way, the cutting blade 512 can press the diaphragm on both sides when cutting and lifting, so as to avoid the displacement of the diaphragm when the blade is inserted or lifted, which will affect the operation. The interior of the housing 509 is also provided with a cleaning block 515. The cleaning block 515 can grind the cutting blade 512 and clean and scrape off the dirt and other residues on the blade. The grinding can keep the cutting blade 512 sharp and achieve better cutting effect.

[0041] The control structure 3 includes a connecting plate 301, a fixed plate 302, a movable plate 303, a rotating seat 304, an eccentric wheel 305, an adjusting block 306, a connecting rod 307, a linkage block 308, and a slide rail 309. A motor 1 is provided on the top of the top plate 7, and a drive wheel 2 is provided on one side of the motor 1. A rotating seat 304 is provided on one side of the top of the top plate 7. The rotating seat 304 and the drive wheel 2 mesh with each other. The control structure 3 can drive the linkage block 308 to move downward to cut the diaphragm through the cooperation between the eccentric wheel 305 and the movable plate 303. Compared with the linkage-type cutting structure, the eccentric wheel 305 type is simpler and more effective, and has a shorter stroke and consumes less mechanical energy.

[0042] An eccentric wheel 305 is provided on one side of the rotating seat 304, and an adjusting block 306 is provided at the bottom of one side of the eccentric wheel 305. A connecting rod 307 is provided at the bottom of the adjusting block 306, and a fixing screw passes through the front of the adjusting block 306.

[0043] A fixed plate 302 is provided on one side of the control cabinet 4, a connecting plate 301 is provided on one side of the fixed plate 302, a slide rail 309 is provided on one side of the front of the connecting plate 301, and a movable plate 303 is provided on the front of the slide rail 309.

[0044] The top of the movable plate 303 is rotatably connected to the bottom of the connecting rod 307. The bottom of the movable plate 303 is provided with a linkage block 308, and the bottom of the linkage block 308 is fixedly connected to the top of the connecting rod 507.

[0045] The working principle and usage process of this invention: When performing cutting operations, the user first places the stacked film at the bottom of the outer casing 509. After placement, the motor 508 is turned on, which drives the power wheel 517 to rotate. The power wheel 517 drives the auxiliary wheel 514 to rotate via the chain belt 511. The movement of the chain belt 511 drives the cutting blade 512 to move, forming a moving cut. The cutting blade 512 is plugged into the chain belt 511. When the cutting blade 512 needs to be replaced after long-term use, it can be disassembled and replaced by loosening the limit screw 516. When the cutting blade 512 moves at high speed, it passes through the cleaning block 515 inside the outer casing 509. The cleaning block 515 can not only clean the dirt on the surface of the cutting blade 512, but also polish it to prevent the blade from becoming dull and affecting the smoothness of the cutting surface. At the same time as the cutting blade 512 moves at high speed, the auxiliary wheel 514 also drives the second bevel gear set 506 to rotate at high speed. The second bevel gear set 506 rotates via the rotating shaft 504 and the universal shaft 503. The first bevel gear set 502 is controlled to rotate at high speed, which drives the fan 513 to rotate at high speed. The air generated by the fan 513 passes through the air duct 501 and is finally discharged outward from the air outlet 510. The discharged air blows to both sides centered on the cutting blade 512, applying air pressure to the diaphragms on both sides. In this way, the cutting blade 512 can effectively prevent the diaphragms from moving during the cutting and lifting processes, eliminating the need for manual pressing and avoiding safety accidents that may affect human health. After starting the motor 508, it can be used for cutting. When motor 1 is turned on, motor 1 drives drive wheel 2 to rotate. Drive wheel 2 controls eccentric wheel 305 to rotate through rotating seat 304. Eccentric wheel 305 drives adjusting block 306 and connecting rod 307 to move up and down. Connecting rod 307 drives movable plate 303 to move vertically up and down along slide rail 309. The length between adjusting block 306 and connecting rod 307 can be adjusted by loosening and tightening fixing screws. The feed stroke of cutting blade 512 can be changed according to actual use needs. The length of cutting film can also be adjusted by adjusting the speed of electrode 1.
