Description

Technical Field

[0001] The present invention relates to the technical field of sheet cutting, and specifically to an automated SMC sheet film tearing and cutting device. Background Art

[0002] SMC sheet is a sheet-shaped molding material, and its main raw materials are composed of SMC special yarn, unsaturated resin, low shrinkage additive, filler and various additives. Before molding, SMC sheets are mostly packed in a formed sheet structure for convenient subsequent processing. Due to the characteristics of the material itself, protective films are usually attached to both sides of the sheet during packing to protect the surface of the SMC sheet and improve the quality of the surface material. However, this layer of film cannot enter the mold for processing together with the SMC material. Therefore, before processing, this layer of film needs to be separated before the SMC sheet can be used for processing.

[0003] In the existing SMC sheet film tearing and cutting process, manual operation usually requires frequent adjustment of the equipment to adapt to materials of different thicknesses and specifications. This manual-dependent operation method not only increases the risk of human error but also results in low production efficiency. In the traditional process, film peeling lacks sufficient precision, and problems such as incomplete film peeling, tearing, or excessive adhesion are likely to occur. After the film layer is peeled off, it cannot be efficiently recycled, resulting in film waste. There is a lack of sufficient automation level, especially in the processes of film tearing, cutting, film winding, and finished product stacking. Many operations still rely on manual or semi-automatic operation, with low efficiency and instability. The equipment does not have an intelligent control and adjustment mechanism for changes in factors such as the thickness of the SMC sheet raw material and the film layer adhesion. This leads to inaccurate or inconsistent processing of the raw materials, thereby affecting the quality of the final product. Summary of the Invention

[0026] The present invention provides an automated SMC sheet film tearing and cutting device. It has the following beneficial effects:

[0027] 1. The present invention has the ability of efficient film tearing and cutting synchronous operation: Through the combination of the linkage film tearing mechanism and the relative cutting mechanism, the automated operation of film tearing and cutting of SMC sheets is completed. The film tearing structure ensures the accurate peeling of the film covered on SMC sheets with different thicknesses through precise adjustment and synchronous movement. The cutting structure can efficiently perform quantitative cutting on the sheet that has been film torn through the precise movement of the tool rest. This synchronism greatly improves the operation efficiency, reduces manual intervention, and lowers the labor cost. The design of the inclined splitting blade and the inclined guiding arc plate effectively controls the film layer peeling process. Through the friction and guiding of the film layer, it is ensured that the film layer can be gradually loosened and smoothly peeled off. This technology ensures the integrity and accuracy of the film layer during the tearing process and will not cause any damage or adverse effects to the SMC sheet raw material.

[0028] The present invention has adjustability and adaptability: The designs of structures such as the guiding opposing frame, guiding opposing roller, receiving frame, and clamping roller in the solution ensure that it can adapt to SMC sheets with different thicknesses and types. This high degree of adjustability enables the device to automatically adjust when facing different product specifications, ensuring high precision and high adaptability of the film tearing and cutting operations, and avoiding adverse effects caused by raw material differences.

[0029] The present invention has the capabilities of efficient film winding and automatic stacking of finished products: Through the winding mechanism of the film winding wheel, the peeled film can be efficiently recycled, while avoiding material waste. In addition, the design of the finished product stacking mechanism and the linked discharging mechanism within the built-in frame ensures that the cut SMC sheets can be automatically conveyed to the next processing step, further improving the degree of automation and reducing manual operations.

[0030] The present invention has the capabilities of intelligence and precise transmission: The design of the synchronous transmission component and the acceleration transmission component, using the rack and pulley structure, ensures that the film peeling and cutting devices can operate precisely synchronously. The combination of the gear structure of the acceleration transmission component and the pulley can efficiently transmit power to the embedded disk, drive the movement of the film peeling tool, and achieve precise film layer peeling and cutting operations. The design of the guiding counterframe enables the entire device to adapt to different working environments and requirements. By adjusting the longitudinal groove and the inclined groove of the guiding counterframe, the movement trajectory and cutting path of the film peeling structure can be easily adjusted to meet the processing requirements of different raw materials. Through the reasonable mechanical structure and the design of the precise transmission system, the friction and wear during the operation of the equipment are reduced, thereby improving the reliability and lifespan of the system and reducing the maintenance and failure rates.

[0047] Please refer to the attached Figure 1 - attached Figure 5The embodiment of the present invention provides an automated SMC sheet film tearing and cutting device, including: an operating frame 1, which is used to fix the structure of the SMC sheet film tearing and cutting device; a reel 2 is located on the operating frame 1, and is used to unwind the SMC sheet material; a cooling roller 3 is located on the operating frame 1, and is used to cool the surface of the SMC sheet material; a built-in frame 4 is located on the operating frame 1, and is used to fix the SMC sheet material cutting and finished product output structure in conjunction with its through-hole structure; a guide roller 5 is located on the operating frame 1, and is used to guide the cooled SMC sheet material; a steering roller 6 is located on the operating frame 1, and is used to turn and guide the SMC sheet material and output it to the film tearing structure; a linkage film tearing mechanism 7 is located on the operating frame 1, and is used to peel the surface of the SMC sheet material. The film-receiving wheel 8 is located on the working frame 1, and is used for rolling up the surface demoulding film peeled off from the SMC sheet material. The relative cutting mechanism 9 is located on the built-in frame 4, and is used for quantitatively cutting the SMC sheet material after the film is torn off. The workbench 10 is located on the built-in frame 4, and is used as a workbench for cutting the formed SMC sheet material. The linkage discharging mechanism 11 is located on the built-in frame 4, and is used to synchronously output the cut finished product with the extension knife holder 94. The unwinding wheel 2 is suspended on one side of the working frame 1, and the cooling roller 3 is rotatably arranged on the side of the working frame 1 close to the unwinding wheel 2. The built-in frame 4 is fixedly connected to the inside of the working frame 1, and the through-hole structure of the built-in frame 4 is arranged on the side of the built-in frame 4 close to the linkage film-tearing mechanism 7, and is located in the output direction of the cooling roller 3. The guide roller 5 is rotatably arranged inside the working frame 1 and is close to the built-in frame 4. The steering roller 6 is rotatably arranged inside the working frame 1 on the side away from the cooling roller 3. The cooling roller 3, the guide roller 5 and the steering roller 6 are located at the same height. The linkage film tearing mechanism 7 is arranged inside the working frame 1 and is located below the steering roller 6. There are two groups of film collecting wheels 8, which are arranged in the working frame 1 in an up-and-down distribution form and are located in the output direction of the linkage film tearing mechanism 7. The relative cutting mechanism 9 is arranged on the inner side wall of the built-in frame 4 close to the linkage film tearing mechanism 7. The workbench 10 is an I-shaped structure and is fixedly connected to the built-in frame 4. The linkage discharging mechanism 11 is arranged on the inner side wall of the built-in frame 4 away from the linkage film tearing mechanism 7. The device is mainly used for film tearing and cutting of SMC sheets. The whole structure is installed on the working frame 1. The unwinding wheel 2 for inputting the SMC sheet material is installed on one side of the working frame 1, and the SMC sheet material required for film tearing and cutting is continuously unwound. The cooling roller 3 installed adjacent to the unwinding wheel 2 is used for cooling conduction of the SMC sheet material before film tearing. The sheet material fed and unwound by the unwinding wheel 2 will first contact the conduction surface of the cooling roller 3. The low-temperature conduction cooling roller 3 will drive the surface of the raw material to cool down, drive the surface coating of the raw material to further solidify, and reduce the fluidity. Then it reaches the guide roller 5 installed on the working frame 1, and then conducts to the steering roller 6 on the other side of the working frame 1 through the surface of the guide roller 5. Then, it is turned and pulled along the surface of the steering roller 6 to be conducted into the working frame 1, and reaches the linkage film tearing mechanism 7.The linkage film tearing mechanism 7 will synchronously adjust the distance of the film peeling structure according to the thickness of different SMC sheet materials. At the same time, using the moving force generated by the distance adjustment, it drives the film peeling structure to cut into the surface coating of the raw material. Then, according to the conveying force of traction conduction, it drives the upper and lower surface coatings of the sheet material to peel off to both sides simultaneously. The two layers of coatings are respectively conducted to two groups of film winding wheels 8 installed in the working frame 1 by the linkage film tearing mechanism 7 for winding. The sheet material after film tearing is conducted between the two layers of coatings to the built-in frame 4, and at the same time enters the built-in frame 4 through the through-hole structure installed on the side wall of the built-in frame 4, and is carried onto the workbench 10 installed in the built-in frame 4. At the same time, according to the cutting size of the sheet material, the relative cutting mechanism 9 installed in the built-in frame 4 is activated to quantitatively cut the raw material entering the built-in frame 4. The linkage discharging mechanism 11 also installed in the built-in frame 4 will synchronously send out the finished SMC sheet products after cutting according to the cutting completion degree of the relative cutting mechanism 9, and finally complete the automatic film tearing and cutting of the SMC sheet.

[0048] Please refer to the appendix Figure 1 - Appendix Figure 10, the linkage film tearing mechanism 7 includes a guiding opposed frame 71, an embedded disc 78 and a synchronous transmission assembly. The guiding opposed frame 71 is fixedly connected inside the working machine frame 1 and is located below the steering roller 6. On the side of the guiding opposed frame 71 close to the steering roller 6, oppositely arranged guiding opposed rollers 72 are rotatably installed. On the side wall of the guiding opposed frame 71, there are upper and lower opposite inclined grooves and longitudinal grooves. The inclined groove of the guiding opposed frame 71 is located between the longitudinal groove and the guiding opposed roller 72. The guiding opposed frame 71 is slidably connected with upper and lower opposite receiving frames 73 through the longitudinal grooves. There are through grooves on the receiving frames 73. A first snap spring 74 is connected between the end of the receiving frame 73 embedded in the end of the longitudinal groove and the inner wall of the longitudinal groove. On the opposite sides of the receiving frames 73, clamping rollers 75 are rotatably installed. The guiding opposed frame 71 is slidably connected with upper and lower opposite inclined knife holders 76 through the inclined grooves. An embedded rack 77 is arranged at the outer end of the inclined knife holder 76. The embedded disc 78 is rotatably connected to the guiding opposed frame 71. At the same time, a spiral groove is arranged on the side wall of the embedded disc 78 facing the guiding opposed frame 71. The embedded rack 77 is embedded in the spiral groove of the embedded disc 78. An inclined peeling blade 79 is fixedly connected to the surface of the inclined knife holder 76. The synchronous transmission assembly is arranged on the guiding opposed frame 71. An inclined guiding arc plate 710 is suspended and installed on the surface of the inclined peeling blade 79 and is arranged parallel to the inclined peeling blade 79. On the side of the inclined guiding arc plate 710 facing the guiding opposed roller 72, there is a horizontal bending part, and a toothed abrasive layer is arranged on the side wall of the bending part. The synchronous transmission assembly includes a traction rack 711 and an acceleration transmission part 712. The traction rack 711 is fixedly connected to one end of the receiving frame 73. The acceleration transmission part 712 is a combined structure of a gear and an output pulley. The gear structure of the acceleration transmission part 712 is rotatably connected to the guiding opposed frame 71. The tooth key end of the traction rack 711 is meshed and connected to the tooth key end of the gear structure of the acceleration transmission part 712. The small-diameter output part of the output pulley structure of the acceleration transmission part 712 is arranged on the rotating shaft of the embedded disc 78. And the linkage film tearing mechanism 7 includes a guiding opposed frame 71 installed on the working machine frame 1. The guiding opposed frame 71 is fixed inside the working machine frame 1. At the same time, oppositely arranged guiding opposed rollers 72 are installed at its input direction. When the SMC sheet material enters the linkage film tearing mechanism 7 through the steering conduction of the steering roller 6, it will first contact the upper and lower extrusion of the two groups of guiding opposed rollers 72. And the guiding opposed frame 71 itself is equipped with upper and lower corresponding inclined grooves and longitudinal grooves. Its inclined groove structure can drive the film peeling structure of the linkage film tearing mechanism 7 to displace and adjust along an inclined angle. The longitudinal grooves installed on the guiding opposed frame 71 can guide the synchronous longitudinal displacement of the two groups of upper and lower opposite receiving frames 73. At the same time, a first snap spring 74 that can limit the displacement of the receiving frame 73 is correspondingly installed at the sliding end of the receiving frame 73 located in the longitudinal groove, so that the receiving frame 73 always moves closer to the inside under the elastic action of the first snap spring 74. Clamping rollers 75 in contact with the sheet material are installed on the opposite sides between the two groups of receiving frames 73. When the sheet material is extruded and guided by the two groups of guiding opposed rollers 72,Arrive between two groups of receiving racks 73 and clamping rollers 75, and contact the clamping rollers 75 vertically. Sheets of different thicknesses will drive the vertically contacting clamping rollers 75 to push the receiving racks 73 they are mounted on to displace to both sides. The two groups of inclined knife racks 76 included in the film stripping structure will displace along the longitudinal grooves of the guiding opposing rack 71. While the receiving racks 73 are displacing, the film structure will synchronously adjust the thin distance under the drive of the synchronous transmission components included in the linkage film tearing mechanism 7. The embedding disc 78 included in the film structure rotates and is installed outside the guiding opposing rack 71, and spiral channels are correspondingly opened on its surface opposite to the guiding opposing rack 71. The clamping rollers 75 installed at the outer ends of the two groups of inclined knife racks 76 are embedded in the spiral channels of the embedding disc 78. When the embedding disc 78 rotates, the two groups of inclined knife racks 76 distributed vertically and oppositely will simultaneously displace inwards or outwards along the inclined grooves of the guiding opposing rack 71. While the receiving racks 73 are correspondingly adjusted according to the raw material thickness, the traction rack 711 included in the synchronous transmission components will displace following one group of receiving racks 73. The acceleration transmission part 712 included in the synchronous transmission components is composed of a group of gear structures plus an acceleration pulley structure. The gear structure of the acceleration transmission part 712 meshes with the traction rack 711 and rotates as the traction rack 711 displaces. At the same time, the gear structure of the acceleration transmission part 712 will drive the acceleration pulley structure of the acceleration transmission part 712 to operate. The output end of the small-diameter pulley of the acceleration pulley structure is installed on the rotating shaft of the embedding disc 78, so that the acceleration transmission part 712 accelerates and conducts the rotational torque of the gear structure to the embedding disc 78, driving the embedding disc 78 to rotate and simultaneously driving the two groups of inclined knife racks 76 to displace along the longitudinal grooves. The inclined peeling blades 79 fixed along the inclination of the inclined knife racks 76 and the inclined guiding arc plates 710 suspended above the inclined peeling blades 79 will synchronously follow the inclined knife racks 76 to displace and contact the surface coating of the sheet raw material. At the same time, the two groups of inclined peeling blades 79 displacing along the inclination angle will synchronously insert into the film coatings on the upper and lower surfaces of the sheet raw material. The inclined guiding arc plates 710 suspended above the inclined peeling blades 79 cooperate with the frosted layer installed on their bending structures to friction the film coating on the raw material surface, driving the film coating to loosen and gradually fall off. As the sheet raw material continues to be conveyed inside the guiding opposing rack 71, the film coatings on the upper and lower surfaces of the raw material are guided and peeled by the inclined peeling blades 79 into the gap formed between the inclined peeling blades 79 and the inclined guiding arc plates 710, conveyed along the gap and passed through the through slots provided on the receiving racks 73, so as to be able to perform automatic film tearing and guiding operations on SMC sheets of different thicknesses. At the same time, the peeled film coatings will be respectively guided to the two film receiving wheels 8 installed on the working machine frame 1 from the through slots of the receiving racks 73 to the upper and lower sides.,

[0049] Please refer to the appendix Figure 1 - appendix Figure 14, the relative cutting mechanism 9 includes opposed guide rails 91, pressing opposed rollers 92, dividing knives 97, a linkage cutting table 98, and a relative transmission assembly. The opposed guide rails 91 are distributed on both sides of the inner side wall of the built-in frame 4 close to the film winding wheel 8 in an opposed manner. The pressing opposed rollers 92 are distributed on the side wall of the built-in frame 4 in an upper and lower opposed manner and are located on both sides of the through-hole structure of the built-in frame 4. Opposed sliding platforms 93 are slidably connected to the opposed guide rails 91 in an upper and lower opposed manner. One end of the opposed sliding platform 93 away from the opposed guide rail 91 is fixedly connected to an extended tool holder 94. Positioning roller holders 95 are embedded and slidably connected to the opposed side walls of the opposed sliding platforms 93. A second return retaining spring 96 is provided between the ends of the positioning roller holders 95 and the opposed sliding platforms 93. The relative transmission assembly is arranged on the built-in frame 4. The dividing knife 97 is fixedly connected to the end of the upper extended tool holder 94. The linkage cutting table 98 is fixedly connected to the end of the lower extended tool holder 94, and an embedding groove is provided inside the linkage cutting table 98. The relative transmission assembly includes an assembly frame 99. The assembly frame 99 is fixedly connected to the inner wall of the built-in frame 4. A central gear 910 is rotatably connected to the middle of the assembly frame 99. Linkage racks 911 are slidably connected to both sides of the assembly frame 99. The linkage racks 911 are correspondingly fixedly connected to the extended tool holders 94 distributed up and down. The sheet material after film tearing is guided between the upper and lower peeled films to the built-in frame 4, passes through the through-hole structure opened on the built-in frame 4 and enters the built-in frame 4, and then contacts the workbench 10 fixed inside the built-in frame 4. The workbench 10 is of an I-shaped structure, and an opening structure with distributed edges on both sides is formed between it and the inner wall of the built-in frame 4. The relative cutting mechanism 9 installed inside the built-in frame 4 performs a quantitative cutting operation on the sheet material after film tearing. The pressing opposed rollers 92 included in the relative cutting mechanism 9 are distributed and installed on the outer side wall of the built-in frame 4 facing the linkage film tearing mechanism 7. The sheet material after film tearing will be clamped and guided by the pressing opposed rollers 92 before entering the built-in frame 4 and then enter the built-in frame 4. The opposed guide rails 91 included in the relative cutting mechanism 9 are installed on the inner side wall of the built-in frame 4 close to the pressing opposed rollers 92, and the opposed sliding platforms 93 are also slidably installed in an upper and lower opposed manner. At the same time, the extended tool holders 94 installed at the ends of the opposed sliding platforms 93 correspond to each other, and a dividing knife 97 for cutting and a linkage cutting table 98 for carrying are respectively installed. When the relative transmission assembly included in the relative cutting mechanism 9 is started, one of the included linkage racks 911 is pushed, driving the central gear 910 installed in the middle of the linkage rack 911 to rotate at the same time, and the other linkage rack 911 is driven to rotate by the central gear 910, so that the two linkage racks 911 drive a set of extended tool holders 94 to move closer to the inside at the same time. The positioning roller holders 95 installed on the two opposed sliding platforms 93 also move closer correspondingly and fit on the sheet material. At the same time, the dividing knives 97 and the linkage cutting tables 98 respectively installed on the two extended tool holders 94 come into contact with each other to cut off the sheet material until the dividing knife 97 completely sinks into the embedding groove provided in the linkage cutting table 98.Thus, the cutting is completed.

[0050] Please refer to the appendix Figure 1 - Appendix Figure 14 , the linkage discharging mechanism 11 includes an extension frame 111, the extension frame 111 is fixedly connected to the inner side of the built-in frame 4 away from the linkage film tearing mechanism 7. One end of the extension frame 111 away from the built-in frame 4 is rotatably installed with a downward pressing curved rod 112, and a bending part is arranged on the side of the downward pressing curved rod 112 close to the workbench 10. One side of the downward pressing curved rod 112 away from the bending part is rotatably connected to a traction rod 113. One end of the traction rod 113 away from the downward pressing curved rod 112 is rotatably connected to the extension tool rest 94. The extension frame 111 is arranged in the side opening of the workbench 10. When the extension tool rest 94 is driven to retract, the linkage discharging mechanism 11 installed on the other side inside the built-in frame 4 is also opened accordingly. The extension frame 111 included in the linkage discharging mechanism 11 is installed on the inner side wall of the built-in frame 4 away from the relative cutting mechanism 9. The downward pressing curved rod 112 included in the linkage discharging mechanism 11 is installed on the extension frame 111 to form a crowbar structure. At the same time, the end of the downward pressing curved rod 112 is a bending structure. One end of the downward pressing curved rod 112 close to the extension tool rest 94 is connected to the extension tool rest 94 through a traction rod 113. When the relative cutting mechanism 9 completes the cutting and drives the extension tool rest 94 to retract, it will push the traction rod 113 to rise, and at the same time drive the downward pressing curved rod 112 to start rotating along the extension frame 111. When the bending structure of the downward pressing curved rod 112 contacts the sheet material finished product of the completed structure, it will continuously press down, pushing the sheet material into the lower part inside the built-in frame 4 for finished product stacking. Thus, after the SMC sheet material is cut, synchronous finished product stacking operation can be carried out.

[0051] Working principle: First of all, this device is mainly aimed at the film tearing and cutting operation of SMC sheets. The overall structure is installed on the operation rack 1. The unwinding wheel 2 for inputting the SMC sheet raw material is installed on one side of the operation rack 1, continuously unwinding the SMC sheet raw material to be torn and cut. The cooling roller 3 adjacent to the unwinding wheel 2 serves as the cooling conduction before the film tearing of the SMC sheet raw material. The sheet raw material fed and unwound by the unwinding wheel 2 will first contact the conduction surface of the cooling roller 3. The cooling roller 3 with low-temperature conduction will drive the surface of the raw material to cool down, drive the surface film of the raw material to further solidify, and reduce the fluidity. Then it reaches the guiding roller 5 installed on the operation rack 1, and then is conducted along the surface of the guiding roller 5 to the turning roller 6 on the other side of the operation rack 1. After that, it is turned and traction-conducted along the surface of the turning roller 6 into the operation rack 1 and reaches the linkage film tearing mechanism 7. The linkage film tearing mechanism 7 will synchronously adjust the distance of the film peeling structure according to the thickness of different SMC sheet raw materials. At the same time, using the moving force of the distance adjustment, it drives the film peeling structure to cut into the surface film of the raw material. Then, according to the conveying force of the traction conduction, it drives the upper and lower surface films of the sheet raw material to peel off to both sides at the same time. The two layers of films are respectively conducted and wound by the two sets of film winding wheels 8 installed in the operation rack 1 through the linkage film tearing mechanism 7. The sheet raw material after film tearing is conducted between the two layers of coatings to the built-in frame 4, and at the same time enters the built-in frame 4 through the through-hole structure installed on the side wall of the built-in frame 4 and is carried on the workbench 10 installed in the built-in frame 4. At the same time, according to the cutting size of the sheet, the relative cutting mechanism 9 installed in the built-in frame 4 is opened to quantitatively cut the raw material entering the built-in frame 4. The linkage discharging mechanism 11 also installed in the built-in frame 4 will synchronously send out the finished SMC sheet products after cutting according to the cutting completion degree of the relative cutting mechanism 9, finally completing the automatic film tearing and cutting of the SMC sheet. The linkage film tearing mechanism 7 includes a guiding counterframe 71 installed on the operation rack 1. The guiding counterframe 71 is fixed inside the operation rack 1, and at the same time, upper and lower opposite guiding counter rollers 72 are installed in its input direction. When the SMC sheet raw material passes through the turning conduction of the turning roller 6 and enters the linkage film tearing mechanism 7, it will first contact the upper and lower extrusion of the two sets of guiding counter rollers 72. The guiding counterframe 71 itself is also equipped with similarly upper and lower corresponding inclined grooves and longitudinal grooves. The inclined groove structure can drive the film peeling structure of the linkage film tearing mechanism 7 to displace and adjust along the inclined angle. The longitudinal grooves installed on the guiding counterframe 71 can guide the two sets of upper and lower opposite receiving frames 73 to synchronously displace longitudinally. At the same time, a snap spring 74 for restricting the displacement of the receiving frame 73 is correspondingly installed at the sliding end of the receiving frame 73 located in the longitudinal groove, so that the receiving frame 73 always moves closer to the inside under the elastic action of the snap spring 74. A clamping roller 75 in contact with the sheet raw material is installed on the opposite side between the two sets of receiving frames 73. When the sheet raw material is squeezed and guided by the two sets of guiding counter rollers 72, it reaches between the two sets of receiving frames 73 and the clamping roller 75 and contacts the clamping roller 75 up and down.Sheet materials of different thicknesses will drive the clamping rollers 75 in contact with the upper and lower parts to push the receiving brackets 73 installed thereon to displace to both sides. The two sets of inclined tool holders 76 included in the film stripping structure will displace along the longitudinal grooves of the guiding opposing bracket 71. While the receiving bracket 73 is displaced, the film structure will synchronously adjust the thin distance under the drive of the synchronous transmission components included in the linkage film tearing mechanism 7. The embedding disc 78 included in the film structure is rotatably installed on the outer side of the guiding opposing bracket 71, and spiral grooves are correspondingly formed on the surface thereof relative to the guiding opposing bracket 71. The clamping rollers 75 installed on the outer ends of the two sets of inclined tool holders 76 are embedded in the spiral grooves of the embedding disc 78. When the embedding disc 78 rotates, the two sets of inclined tool holders 76 distributed oppositely up and down will simultaneously displace inwards or outwards along the inclined grooves of the guiding opposing bracket 71. While the receiving bracket 73 is correspondingly adjusted according to the material thickness, the traction rack 711 included in the synchronous transmission components will displace following one set of receiving brackets 73. The acceleration transmission member 712 included in the synchronous transmission components is composed of a set of gear structure plus an acceleration pulley structure. The gear structure of the acceleration transmission member 712 meshes with the traction rack 711 and rotates along with the displacement of the traction rack 711. At the same time, the gear structure of the acceleration transmission member 712 will drive the acceleration pulley structure of the acceleration transmission member 712 to operate. The output end of the small-diameter pulley of the acceleration pulley structure is installed on the rotating shaft of the embedding disc 78, so that the acceleration transmission member 712 accelerates the transmission of the rotational torque of the gear structure to the embedding disc 78, driving the embedding disc 78 to rotate and simultaneously driving the two sets of inclined tool holders 76 to displace along the longitudinal grooves. The inclined peeling blades 79 fixed along the inclination of the inclined tool holders 76 and the inclined guiding arc plates 710 suspended above the inclined peeling blades 79 will synchronously displace following the inclined tool holders 76 and contact the surface coating of the sheet material. At the same time, the two sets of inclined peeling blades 79 displacing along the inclination angle will synchronously insert into the film coatings on the upper and lower surfaces of the sheet material. The inclined guiding arc plates 710 suspended above the inclined peeling blades 79 cooperate with the frosted layer installed on their bending structures to friction the film coating on the raw material surface, driving the film coating to loosen and gradually fall off. As the sheet material continuously conveys inside the guiding opposing bracket 71, the film coatings on the upper and lower surfaces of the raw material are guided and peeled by the inclined peeling blades 79 into the gap formed between the inclined peeling blades 79 and the inclined guiding arc plates 710, conveyed along the gap and pass through the through slots provided on the receiving bracket 73, so as to be able to perform automatic film tearing and guiding operations on SMC sheet materials of different thicknesses. At the same time, the peeled film coatings will be respectively guided to the upper and lower sides along the through slots of the receiving bracket 73 to the two sets of film collecting rollers 8 installed on the working machine frame 1, and the peeled film coatings are collected by the film collecting rollers 8. The sheet material after film tearing is guided between the upper and lower peeled film coatings to the built-in frame 4, passes through the through hole structure provided on the built-in frame 4 and enters the built-in frame 4, and then contacts the working table 10 fixed inside the built-in frame 4. The working table 10 is of an I-shaped structure, and an opening structure with distributed edges on both sides is formed between its inner wall and the inner wall of the built-in frame 4.The relative cutting mechanism 9 installed inside the built-in frame 4 performs a quantitative cutting operation on the sheet material after the film tearing is completed. The pressing opposed rollers 92 included in the relative cutting mechanism 9 are distributed and installed on the outer side wall of the built-in frame 4 facing the linkage film tearing mechanism 7. The sheet material after the film tearing is completed will pass through the clamping and guiding of the pressing opposed rollers 92 before entering the built-in frame 4, and then enter the built-in frame 4. The opposed guide rails 91 included in the relative cutting mechanism 9 are installed on the inner side wall of the built-in frame 4 close to the pressing opposed rollers 92, and the opposed sliding tables 93 are also slidably installed in a vertically opposed manner. At the same time, the extension tool holders 94 installed at the ends of the opposed sliding tables 93 correspond to each other, and a dividing knife 97 for cutting and a linkage cutting table 98 for carrying are respectively installed. When the relative transmission assembly included in the relative cutting mechanism 9 is started, one side of the linkage rack 911 included therein is pushed, and at the same time, the central gear 910 installed in the middle of the linkage rack 911 is driven to rotate, while the other side of the linkage rack 911 is driven to rotate by the central gear 910, so that the two sides of the linkage rack 911 drive a set of extension tool holders 94 to move closer to the inside at the same time. The positioning roller frames 95 installed on the two sides of the opposed sliding tables 93 also move closer correspondingly and fit on the sheet material. At the same time, the dividing knives 97 respectively installed on the two sides of the extension tool holders 94 come into contact with the linkage cutting table 98 to cut the sheet until the dividing knife 97 completely sinks into the embedding groove provided in the linkage cutting table 98, thus completing the cutting. When the extension tool holder 94 is driven to retract, the linkage discharging mechanism 11 installed on the other side inside the built-in frame 4 is also opened at the same time. The extension frame 111 included in the linkage discharging mechanism 11 is installed on the inner side wall of the built-in frame 4 away from the relative cutting mechanism 9. The downward pressing curved rod 112 included in the linkage discharging mechanism 11 is installed on the extension frame 111 to form a crowbar structure. At the same time, the end of the downward pressing curved rod 112 is a curved structure, and one end of the downward pressing curved rod 112 close to the extension tool holder 94 is connected to the extension tool holder 94 through a traction rod 113. When the relative cutting mechanism 9 completes the cutting and drives the extension tool holder 94 to retract, it will push the traction rod 113 to rise, and at the same time drive the downward pressing curved rod 112 to start rotating along the extension frame 111. When the curved structure of the downward pressing curved rod 112 touches the finished sheet material, it will continuously press down to push the sheet into the lower part inside the built-in frame 4 for stacking and placing the finished products. Thus, after the SMC sheet is cut, the synchronous stacking and placing operation of the finished products can be carried out.
