A thickness detection device for silica gel heating sheet production and a method of using the same

Abstract

The present application relates to the technical field of silica gel heating sheet production equipment, and discloses a thickness detection device for silica gel heating sheet production and a use method thereof. The present application aims to solve the problem that the standard thickness of silica gel heating sheet is 1.5 mm, and even if the thickness of the produced silica gel heating sheet is not in conformity with the standard, there will only be a difference of zero point several millimeters, which is difficult to be distinguished by naked eyes and measured, and the non-conforming silica gel heating sheet is usually only thicker than the standard thickness. Since the thickness difference is very small, it is usually difficult to perform secondary processing on the non-conforming silica gel heating sheet after detection, thereby increasing the production cost of the silica gel heating sheet. The present device realizes thickness detection of the silica gel heating sheet and trimming of the non-conforming part at the same time, so that the thickness of the silica gel heating sheet after detection is consistent and in conformity with the standard, and the detected part can be cut at the same time, thereby improving the production and detection efficiency of the silica gel heating sheet.

Description

Technical Field

[0001] This invention relates to the field of silicone heating element production equipment technology, specifically to a thickness detection device for silicone heating element production and its usage method. Background Technology

[0002] Silicone heating pads are flexible electric heating film elements made of high-temperature resistant, high-thermal-conductivity, excellent insulation, and high-strength silicone rubber, high-temperature resistant fiber-reinforced materials, and a metal heating film circuit. They consist of two sheets of fiberglass cloth and double-layered silicone rubber pressed together to form a silicone-fiberglass cloth. Because it is a thin sheet product (standard thickness 1.5mm), it has excellent flexibility and can make complete and tight contact with the object being heated.

[0003] Since silicone heating pads are made of silicone fiberglass cloth composed of two sheets of glass fiber cloth and double-layer pressed silicone, uneven thickness is inevitable during the production process. The standard thickness of silicone heating pads is 1.5mm. Even if the thickness of the produced silicone heating pads is non-compliant, the difference will only be a few tenths of a millimeter, which is difficult to distinguish with the naked eye and is also difficult to measure. Moreover, non-compliant silicone heating pads are usually only thicker than the standard thickness. Due to the extremely small thickness difference, it is usually difficult to reprocess non-compliant silicone heating pads after inspection, thus requiring them to be scrapped, which increases the production cost of silicone heating pads.

The other third pulley is arranged at the end of the locking rod. The second transmission belt is sleeved on the two third pulleys.

[0011] Preferably, the method of using the thickness detection device for silicone heating element production includes the following steps:

[0012] S1: First, the rolled silicone heating sheet is wound onto the winding equipment. The height of the measuring blade is adjusted according to the thickness detection standard. The threaded rod is rotated by manually turning the adjusting block. By controlling the rotation direction and number of turns of the threaded rod, the rising or falling height of the adjusting frame is finely adjusted, thereby adjusting the height of the measuring blade. One end of the silicone heating sheet is held and passed through the flattening conveyor and the linkage cutting device, so that its end passes through the pulling discharge component. The silicone heating sheet is continuously pulled at the pulling discharge component, so that the silicone heating sheet wound on the winding equipment is continuously conveyed in the flattening conveyor and the linkage cutting device.

[0013] S2: The distance between the first and second conveying rollers in each group is slightly greater than 1.5 mm to ensure that the silicone heating sheet can pass smoothly between the first and second conveying rollers. The circular limiting plates on both sides of the second conveying roller can limit the silicone heating sheet located between them. The width of the second conveying roller is the same as the width of the silicone heating sheet, which applies a lateral limiting effect to the silicone heating sheet. The first and second conveying rollers apply a longitudinal limiting effect to it to ensure that it is conveyed in a horizontal state.

[0014] S3: During the conveying process of the silicone heating pad, if its thickness is compliant, the bottom of the silicone heating pad will always be in contact with the top of the measuring blade during the conveying process. If its thickness is not compliant, the thicker part of the silicone heating pad will be trimmed by the measuring blade during the conveying process, and the excess part will be cut off.

[0015] S4: When the silicone heating element is being conveyed, the locking block is unable to rotate because the cross pin is inside the cross slot. Furthermore, the drive block is locked inside the sliding groove, ensuring the first connecting frame remains horizontal. This guarantees the silicone heating element is always conveyed horizontally when pulled. When cutting the silicone heating element to the required length after trimming or inspection, the locking rod is rotated counterclockwise. The arc groove and drive block work together to slide the locking block away from the cross slot, disengaging the cross pin. This allows the first connecting frame to rotate around its rotating connection with the mounting base. Simultaneously, the measuring blade changes from an inclined to a vertical position, and the second and first clamping rollers clamp and fix the silicone heating element in both directions. Pulling down the end of the silicone heating element causes the discharge frame to descend synchronously, and the first connecting frame flips downwards, bringing the bottom surface of the silicone heating element into contact with the cutting end of the measuring blade, thus completing the cutting operation.

[0016] S5: Remove the cut silicone heating sheet, then turn the locking lever clockwise to relock the horizontal state of the first connecting frame and the first mating roller. Then, pass the remaining end of the silicone heating sheet back between the first mating roller and the second mating roller, and pass it through the feeding port for subsequent inspection and cutting operations.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] In operation, this device first winds a roll of silicone heating sheet onto a winding machine. The height of the measuring blade tip is then fine-tuned using a fine-tuning measuring and trimming device. One end of the silicone heating sheet is held and passed through both the flattening conveyor and the linked cutting device, before passing through the pull-out assembly. The pull-out assembly continuously pulls the silicone heating sheet, ensuring it is continuously conveyed within the flattening conveyor and the linked cutting device. The flattening conveyor ensures the silicone heating sheet travels in a straight line without deviation during this process. If the thickness of the silicone heating sheet is within specifications, the conveying process will... The bottom end is always conveyed in contact with the tip of the measuring blade. If the thickness is not up to standard, the thicker part of the silicone heating sheet will be trimmed by the measuring blade during the conveying process. The trimmed part is then conveyed towards the pull-out component. By controlling the linkage cutting device, the trimmed or compliant silicone heating sheet can be cut to the required length. This device achieves the simultaneous thickness detection and trimming of non-compliant parts of the silicone heating sheet, ensuring that the thickness of the silicone heating sheet is consistent and compliant after detection, eliminating the need for secondary processing. Furthermore, the device can perform cutting work on the detected part at the same time, thereby improving the production and inspection efficiency of silicone heating sheets.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1 to 18 The present invention provides a technical solution including a winding device 1, the winding device 1 being arranged on a horizontal plane, a flattening conveyor device 2 being provided on one side of the winding device 1, a fine-tuning measuring and trimming device 3 being provided on the side of the flattening conveyor device 2 away from the winding device 1, a measuring blade 4 being vertically arranged at the top of the fine-tuning measuring and trimming device 3, the top of the measuring blade 4 being a cutting end, and the cutting end of the measuring blade 4 being inclined towards the winding device 1, a pulling discharge assembly 5 being provided on the side of the fine-tuning measuring and trimming device 3 away from the flattening conveyor device 2, and a linkage cutting device 6 being provided on both sides of the fine-tuning measuring and trimming device 3.

[0040] In this embodiment, as Figure 2As shown, the flattening conveying device 2 includes a conveying frame 21, a first conveying roller 22, and a second conveying roller 23. The conveying frame 21 is disposed on one side of the winding device 1. There are several first conveying rollers 22 and second conveying rollers 23. Each first conveying roller 22 and second conveying roller 23 forms a group. Several groups of first conveying rollers 22 and second conveying rollers 23 are equidistantly and horizontally disposed on the top of the conveying frame 21. The first conveying roller 22 in each group is located directly above the second conveying roller 23. Both ends of each first conveying roller 22 and second conveying roller 23 are rotatably connected to both ends of the top of the conveying frame 21. Both ends of each second conveying roller 23 are provided with a circular limiting plate 24 that is coaxial with the second conveying roller 23 and has a diameter slightly larger than the diameter of the second conveying roller 23.

[0041] The distance between the first conveying roller 22 and the second conveying roller 23 in each group is slightly greater than 1.5 mm to ensure that the silicone heating sheet can pass smoothly between the first conveying roller 22 and the second conveying roller 23. The circular limiting plates 24 on both sides of the second conveying roller 23 can limit the silicone heating sheet located between them. The width of the second conveying roller 23 is the same as the width of the silicone heating sheet, which applies a lateral limit to the silicone heating sheet to prevent it from shifting during the pulling process. During the pulling process, the first conveying roller 22 and the second conveying roller 23 are rotated by force to ensure that the silicone heating sheet is transported relatively smoothly between the first conveying roller 22 and the second conveying roller 23. The first conveying roller 22 and the second conveying roller 23 apply a longitudinal limiting effect to ensure that it is transported in a horizontal state, thereby ensuring the smooth progress of subsequent thickness detection operations.

[0042] In this embodiment, as Figures 13 to 15 As shown, the fine-tuning measuring and trimming device 3 includes a trimming frame 31, an adjusting frame 32, a connecting block 33, a threaded rod 34, and an adjusting block 35. The trimming frame 31 is located on the side of the conveyor frame 21 away from the winding device 1. The adjusting frame 32 is located on top of the trimming frame 31 and slides vertically with it. The threaded rod 34 passes through the bottom of the trimming frame 31 and passes through the adjusting frame 32, which is threadedly connected to it. The adjusting block 35 is located at the bottom of the threaded rod 34. The connecting block 33 is located on top of the adjusting frame 32, and the bottom of the connecting block 33 is rotatably connected to the top of the adjusting frame 32. The measuring blade 4 is vertically located on top of the connecting block 33, and the cutting end of the measuring blade 4 is inclined towards the winding device 1.

[0043] Before conveying and measuring the thickness of the silicone heating sheet, the height of the measuring blade 4 is adjusted according to the thickness measurement standard. The adjusting block 35 is manually rotated to drive the threaded rod 34 to rotate. By controlling the rotation direction and number of turns of the threaded rod 34, the rising or falling height of the adjusting frame 32 is finely adjusted, thereby adjusting the height of the measuring blade 4. During the conveying process of the silicone heating sheet, if its thickness is compliant, the bottom end of the silicone heating sheet is always in contact with the top end of the measuring blade 4. If its thickness is non-compliant, the thicker part of the silicone heating sheet will be trimmed by the measuring blade 4 during the conveying process, and the excess part will be cut off. This achieves the effect of measuring the thickness of the silicone heating sheet during the conveying process and trimming silicone heating sheets with non-compliant thickness.

[0044] In this embodiment, as Figures 4 to 14 As shown, the pull-out assembly 5 includes an outlet seat 51, an outlet frame 52, and a first spring 53. The outlet seat 51 is located on the side of the trimming frame 31 away from the conveying frame 21. The side end of the outlet seat 51 has a through-hole. The outlet frame 52 is located at the through-hole on the side end of the outlet seat 51. The bottom of the outlet frame 52 passes through the bottom end of the through-hole and slides up and down with it. Several first springs 53 are provided. Several first springs 53 are spaced apart at the bottom of the outlet frame 52, and the bottom of several first springs 53 are all fixedly connected to the bottom inside the outlet frame 52. The top of the outlet frame 52 and the top of the through-hole on the side end of the outlet seat 51 form a pull-out port 54.

[0045] The linkage cutting device 6 includes a cooperating cutting component 61, a locking component 62, a linkage adjusting cutter head component 63, and a cooperating clamping component 64. The cooperating cutting component 61 is disposed between the pulling discharge component 5 and the fine-tuning measuring and trimming device 3. The locking component 62 is disposed on the cooperating cutting component 61. The cooperating clamping component 64 is disposed between the conveyor frame 21 and the trimming frame 31. The linkage adjusting cutter head component 63 is disposed on the side of the fine-tuning measuring and trimming device 3 and the cooperating cutting component 61. The cooperating cutting component 61 includes a first connecting frame 611, a second connecting frame 612, a first cooperating roller 613, a second cooperating roller 614, a mounting base 615, a third connecting frame 616, and a second spring 617. The mounting base 615 is disposed between the discharge seat 51 and the trimming frame 31. The two sides of the first connecting frame 611 are rotatably connected to the two ends of the top of the mounting base 615. The two ends of the first cooperating roller 613 are respectively connected to the side of the first connecting frame 611 away from the mounting base 615. The first connecting frame 611 is horizontally arranged, and two second springs 617 are provided. The two second springs 617 are symmetrically arranged at both ends of the bottom of the first connecting frame 611. One end of each of the two second springs 617 is connected to both ends of the bottom of the first connecting frame 611, and the other end of each of the two second springs 617 is fixedly connected to the side end of the mounting base 615. The two ends of one side of the second connecting frame 612 are rotatably connected to the two ends of the first connecting frame 611, and the two ends of the other side of the second connecting frame 612 are rotatably connected to the two ends of the top of the discharge frame 52. The second connecting frame 612 is horizontally arranged. The third connecting frame 616 is horizontally arranged directly above the second connecting frame 612 and fixedly connected to the side end of the discharge base 51. The two ends of the second cooperating roller 614 are rotatably connected to the two ends of the third connecting frame 616. The second cooperating roller 614 is located directly above the first cooperating roller 613, and the distance between the two is the same as the width of the feeding port 54.

[0046] The locking assembly 62 includes a locking rod 621, a locking block 622, an arc-shaped groove 623, a driving block 624, a cross pin 625, a cross slot 626, and a sliding groove 627. The mounting base 615 and the first connecting bracket 611 have corresponding through holes on one side. The mounting base 615 has a cross slot 626 inside its other side. The locking rod 621 passes through the through hole on one side of the mounting base 615 and is located inside the first connecting bracket 611. The locking rod 621 is hollow and its end near the cross slot 626 is open. The side end of 21 is provided with an arc-shaped groove 623. The locking rod 621 is slidably connected to a locking block 622. The top of the locking block 622 is provided with a driving block 624 and the driving block 624 is slidably engaged with the arc-shaped groove 623. The first connecting bracket 611 is provided with a sliding groove 627 and the top of the driving block 624 is locked in the sliding groove 627 and slides in a straight line towards the cross slot 626. The locking block 622 is provided with a cross pin 625 at one end near the cross slot 626 and the cross pin 625 is located inside the cross slot 626.

[0047] When the silicone heating element is being conveyed, the locking block 622 is unable to rotate because the cross pin 625 is inside the cross slot 626, and the driving block 624 is engaged inside the sliding groove 627. Therefore, the first connecting frame 611 is locked in a horizontal position, ensuring that the silicone heating element is always conveyed horizontally when pulled. The silicone heating element is conveyed between the first mating roller 613 and the second mating roller 614, maintaining a relatively stable state. When the silicone heating element, after trimming or inspection, needs to be cut to the required length, the locking rod 621 is rotated counterclockwise. With the cooperation of the arc groove 623 and the driving block 624, the locking block 622 slides linearly away from the cross slot 626, allowing the heating element to move horizontally. The cross pin 625 disengages from the cross slot 626, allowing the first connecting frame 611 to rotate about the pivot point with the mounting base 615. At this point, simply pull down the end of the silicone heating sheet, and the discharge frame 52 descends simultaneously. The first connecting frame 611 flips downward, causing the bottom surface of the silicone heating sheet to contact the cutting end of the measuring blade 4, thus achieving the cutting operation of the silicone heating sheet. Remove the cut silicone heating sheet, then rotate the locking lever 621 clockwise to relock the horizontal state of the first connecting frame 611 and the first mating roller 613. Then, pass the remaining end of the silicone heating sheet back between the first mating roller 613 and the second mating roller 614 and through the feeding port 54 to facilitate subsequent inspection and cutting operations.

The first transmission belt 633 is sleeved on the first pulley 631 and the second pulley 632. The first gear 634 is disposed on the side of the second pulley 632 and shares a common belt with it. The shaft is set, and the second gear 635 is located at the rotatable connection between the adjusting frame 32 and the connecting block 33, and the first gear 634 and the second gear 635 mesh. The mating clamping assembly 64 includes a first clamping seat 640, a second clamping seat 641, a first clamping roller 642, a second clamping roller 643, a lifting seat 644, a lifting rod 645, a toothed rod 646, a third pulley 647, a second transmission belt 648, and a third gear 649. The first clamping seat 640 is located between the conveying frame 21 and the trimming frame 31, and the lifting seat 644... 4.

The two sides of the second clamping roller 643 are respectively rotatably connected to the two sides of the second clamping seat 641. The first clamping roller 642 and the first mating roller are... The height of the second clamping roller 643 is higher than that of the second mating roller 614. There are two third pulleys 647. The toothed rod 646 is located on the side end of one of the lifting rods 645. The third gear 649 and one of the third pulleys 647 are coaxially rotatably connected to the side end of one of the lifting seats 644, and the third gear 649 meshes with the toothed rod 646. The other third pulley 647 is located at the end of the locking rod 621. The second transmission belt 648 is sleeved on the two third pulleys 647.

[0049] As the locking lever 621 is rotated counterclockwise to release the horizontal state of the first connecting frame 611, the first pulley 631 rotates synchronously. Under the transmission of the first transmission belt 633, the first gear 634 connected to the second pulley 632 rotates counterclockwise, which in turn drives the second gear 635 to rotate clockwise. This causes the measuring blade 4 to change from an inclined state to a vertical state, raising its top height and pushing the bottom surface of the silicone heating pad it contacts upwards. This increases the force-bearing surface between the measuring blade 4 and the silicone heating pad, making the cutting operation more favorable.

[0050] While the locking lever 621 is rotated counterclockwise to release the horizontal state of the first connecting frame 611, the third gear 649 is driven to rotate counterclockwise by the second transmission belt 648 and the two third pulleys 647. This causes the toothed rod 646, which meshes with the gear, to slide downwards, and in turn causes the second clamping roller 643 to slide downwards until the second clamping roller 643 and the first clamping roller 642 clamp and fix the silicone heating sheet located between them in both vertical and horizontal directions. This ensures that one end of the silicone heating sheet is fixed during the cutting process, making it easier to bear force and cut. Furthermore, the uncut end of the silicone heating sheet remains fixed after cutting, preventing it from falling off. This facilitates subsequent continuous conveying for inspection, trimming, and cutting operations.

[0051] The method of use and advantages of the present invention: The method of using the thickness detection device for silicone heating element production is as follows:

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 As shown:

[0053] S1: First, the rolled silicone heating sheet is wound onto the winding device 1. The height of the measuring blade 4 is adjusted according to the thickness detection standard. The threaded rod 34 is rotated by manually rotating the adjusting block 35. By controlling the rotation direction and number of turns of the threaded rod 34, the rising or falling height of the adjusting frame 32 is finely adjusted, thereby adjusting the height of the measuring blade 4. One end of the silicone heating sheet is held and passed through the flattening conveying device 2 and the linkage cutting device 6 respectively, so that its end passes through the pulling discharge component 5. The silicone heating sheet is continuously pulled at the pulling discharge component 5, so that the silicone heating sheet wound on the winding device 1 is continuously conveyed in the flattening conveying device 2 and the linkage cutting device 6.

[0054] S2: The distance between the first conveying roller 22 and the second conveying roller 23 in each group is slightly greater than 1.5 mm to ensure that the silicone heating sheet can pass smoothly between the first conveying roller 22 and the second conveying roller 23. The circular limiting plates 24 on both sides of the second conveying roller 23 can limit the silicone heating sheet located between them. The width of the second conveying roller 23 is the same as the width of the silicone heating sheet, which applies a lateral limiting effect to the silicone heating sheet. The first conveying roller 22 and the second conveying roller 23 apply a longitudinal limiting effect to it to ensure that it is conveyed in a horizontal state.

[0055] S3: During the conveying process of the silicone heating pad, if its thickness is compliant, the bottom of the silicone heating pad will always be in contact with the top of the measuring blade 4 during the conveying process. If its thickness is not compliant, the thicker part of the silicone heating pad will be trimmed by the measuring blade 4 during the conveying process, and the excess part will be cut off.

[0056] S4: When the silicone heating element is being conveyed, the locking block 622 is unable to rotate because the cross pin 625 is inside the cross slot 626, and the driving block 624 is locked inside the sliding groove 627. Therefore, the first connecting bracket 611 is locked in a horizontal state, ensuring that the silicone heating element is always conveyed horizontally when pulled. When the silicone heating element, after being trimmed or inspected and approved, is cut to the required length, the locking rod 621 is rotated counterclockwise. With the cooperation of the arc groove 623 and the driving block 624, the locking block 622 is moved away from the cross slot 626. The cross pin 625 slides in a straight line, disengaging from the cross slot 626. This allows the first connecting frame 611 to rotate around the pivot point with the mounting base 615. Simultaneously, the measuring blade 4 is adjusted from an inclined state to a vertical state, and the second clamping roller 643 and the first clamping roller 642 clamp and fix the silicone heating sheet located between them in both vertical and horizontal directions. At this point, simply pull down the end of the silicone heating sheet, and the discharge frame 52 descends synchronously. The first connecting frame 611 flips downward, causing the bottom surface of the silicone heating sheet to contact the cutting end of the measuring blade 4, thus achieving the cutting operation of the silicone heating sheet.

[0057] S5: Remove the cut silicone heating sheet, then rotate the locking lever 621 clockwise to relock the horizontal state of the first connecting frame 611 and the first mating roller 613. Then, pass the remaining end of the silicone heating sheet back through the first mating roller 613 and the second mating roller 614 and through the material pulling port 54 to carry out subsequent inspection and cutting operations.

6. A method of using a thickness detection device for the production of silicone heating sheets, comprising the following steps: S1: First, the rolled silicone heating sheet is wound onto the winding device (1). The height of the measuring blade (4) is adjusted according to the thickness detection standard. The threaded rod (34) is rotated by manually rotating the adjusting block (35). The rising or falling height of the adjusting frame (32) is finely adjusted by controlling the rotation direction and number of turns of the threaded rod (34), and the height of the measuring blade (4) is adjusted accordingly. One end of the silicone heating sheet is held and passed through the flattening conveying device (2) and the linkage cutting device (6) respectively, so that the end passes through the pulling discharge assembly (5). The silicone heating sheet is continuously pulled at the pulling discharge assembly (5), so that the silicone heating sheet wound on the winding device (1) is continuously conveyed in the flattening conveying device (2) and the linkage cutting device (6). S2: The distance between the first conveying roller (22) and the second conveying roller (23) in each group is slightly greater than 1.5 mm to ensure that the silicone heating sheet can pass smoothly between the first conveying roller (22) and the second conveying roller (23). The circular limiting plates (24) on both sides of the second conveying roller (23) can limit the silicone heating sheet located between them. The width of the second conveying roller (23) is consistent with the width of the silicone heating sheet, which applies a lateral limiting effect to the silicone heating sheet. The first conveying roller (22) and the second conveying roller (23) apply a longitudinal limiting effect to it to ensure that it is conveyed in a horizontal state. S3: During the conveying process of the silicone heating pad, if its thickness is compliant, the bottom of the silicone heating pad will always be in contact with the top of the measuring blade (4) during the conveying process. If its thickness is not compliant, the thicker part of the silicone heating pad will be trimmed by the measuring blade (4) during the conveying process, and the excess part will be cut off. S4: When the silicone heating element is being conveyed, the locking block (622) is unable to rotate because the cross pin (625) is inside the cross slot (626). Furthermore, because the drive block (624) is engaged inside the sliding groove (627), the first connecting frame (611) is locked in a horizontal position, ensuring the silicone heating element is always conveyed horizontally when pulled. When cutting the silicone heating element to the required length after trimming or inspection, the locking rod (621) is rotated counterclockwise. With the cooperation of the arc groove (623) and the drive block (624), the locking block (622) is moved away from the cross slot (626). The cross pin (625) slides in a straight line in the direction of the cross, causing the cross pin (625) to disengage from the cross slot (626), thereby allowing the first connecting frame (611) to rotate around the rotating connection point with the mounting base (615). At the same time, the measuring blade (4) is adjusted from an inclined state to a vertical state, and the second clamping roller (643) and the first clamping roller (642) clamp and fix the silicone heating sheet located between them in both the upper and lower directions. At this time, it is only necessary to pull down the end of the silicone heating sheet, and the discharge frame (52) descends synchronously. The first connecting frame (611) flips down, thereby causing the bottom surface of the silicone heating sheet to contact the cutting end of the measuring blade (4), thus realizing the cutting operation of the silicone heating sheet. S5: Remove the cut silicone heating sheet, then rotate the locking lever (621) clockwise to relock the horizontal state of the first connecting frame (611) and the first mating roller (613). Then, pass the remaining end of the silicone heating sheet back through the first mating roller (613) and the second mating roller (614) and through the feeding port (54) to carry out subsequent inspection and cutting operations.
