Description

Technical Field

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

[0002] SMC sheet is a kind of sheet molding material, the main raw materials are SMC special yarn, unsaturated resin, low shrinkage additives, fillers and various additives. Before molding, SMC sheets are mostly packaged in the already formed sheet structure to facilitate subsequent processing. Due to the characteristics of the material itself, protective films are usually attached to both sides of the sheet during packaging to protect the surface of the SMC sheet and improve the quality of the surface material. However, this film cannot be processed together with the SMC material in the mold, so before processing, this film needs to be separated so that the SMC sheet can be used for processing.

[0003] In the existing SMC sheet film tearing and cutting process, manual operation usually requires frequent equipment adjustment to adapt to materials of different thicknesses and specifications. This manual-dependent operation method not only increases the risk of human error, but also leads to low production efficiency. In the traditional process, the film peeling is not accurate enough, and it is easy to have problems such as incomplete film peeling, tearing or excessive adhesion. The film cannot be efficiently recycled after peeling, resulting in film waste. There is a lack of sufficient automation level, especially in the film tearing, cutting, film collection and finished product stacking. Many operations still rely on manual or semi-automatic operations, which are inefficient and prone to instability. The equipment has no intelligent control and adjustment mechanism for changes in factors such as the thickness of the SMC sheet raw material and the adhesion of the film layer. This leads to inaccurate or inconsistent processing of raw materials, which in turn affects the quality of the final product. Summary of the invention

When the relative cutting mechanism 9 completes the cutting and drives the extension tool holder 94 to retreat, the traction rod 113 will be pushed up, and the downward pressing curved rod 112 will be driven to start rotating along the extension frame 111. When the curved structure of the downward pressing curved rod 112 contacts the finished sheet material with the completed structure, it will continue to press down and push the sheet material into the bottom of the internal frame 4 for finished product stacking, so that after the SMC sheet material is cut, the finished product stacking operation can be carried out synchronously.

[0023] Working principle: First of all, the device is mainly used for film tearing and cutting of SMC sheets. The overall structure is installed on the working frame 1. The unwinding wheel 2, which is used as the input of SMC sheet raw materials, is installed on one side of the working frame 1. It continuously unwinds the SMC sheet raw materials required for film tearing and cutting, and the cooling roller 3 installed adjacent to the unwinding wheel 2 serves as the cooling conduction of the SMC sheet raw materials before film tearing. The sheet raw materials 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 materials to cool down, drive the surface coating of the raw materials to further solidify, and reduce the fluidity. Then it reaches the guide roller 5 installed on the working frame 1, and then conducts through the surface of the guide roller 5 to the steering roller 6 on the other side of the working frame 1, and then turns along the surface of the steering roller 6. The film is then pulled and transmitted to the operating frame 1 and reaches the linkage film-tearing mechanism 7. The linkage film-tearing mechanism 7 will synchronously adjust the distance of the film-tearing structure according to the thickness of the different SMC sheet raw materials, and use the motion force of the distance adjustment to drive the film-tearing structure to cut into the surface coating of the raw material. Then, according to the conveying force transmitted by the traction, the films on the upper and lower surfaces of the sheet raw material are driven to be peeled off to both sides at the same time, and the two layers of coating are respectively transmitted and wound to the two sets of film-receiving wheels 8 installed in the operating frame 1 through the linkage film-tearing mechanism 7, and the sheet raw material that has completed the film-tearing is transmitted to the built-in frame 4 along the two layers of coating, and at the same time, it enters the built-in frame 4 along 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 of the sheet The relative cutting mechanism 9 installed in the built-in frame 4 is turned on to quantitatively cut the raw materials entering the built-in frame 4, and the linkage discharging mechanism 11 installed in the built-in frame 4 will synchronously send out the finished SMC sheet 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. The linkage film tearing mechanism 7 includes a guide opposing frame 71 installed on the working frame 1, and the guide opposing frame 71 is fixed inside the working frame 1. At the same time, the upper and lower relative guide opposing rollers 72 are installed in its input direction. When the SMC sheet raw material passes through the steering conduction of the steering roller 6 and enters the linkage film tearing mechanism 7, it will first contact the upper and lower extrusion of the two sets of guide opposing rollers 72, and the guide opposing frame 7 1 is also equipped with the same upper and lower corresponding inclined grooves and longitudinal grooves. The inclined groove structure can drive the film stripping structure of the linkage film stripping mechanism 7 to be able to move and adjust along the inclined angle, and the longitudinal groove installed on the guide opposing frame 71 can guide the two groups of receiving frames 73 opposite to each other to move longitudinally synchronously. At the same time, the sliding end of the receiving frame 73 located in the longitudinal groove is correspondingly equipped with a clamping spring 74 that can limit the displacement of the receiving frame 73, so that the receiving frame 73 always moves inward under the elastic action of the clamping spring 74. The opposite side between the two groups of receiving frames 73 is equipped with a clamping roller 75 that contacts the sheet material. When the sheet material is squeezed and guided by the two groups of guide opposing rollers 72, it reaches between the two groups of receiving frames 73 and the clamping roller 75, and contacts the clamping roller 75 up and down.The sheet materials of different thicknesses will drive the clamping rollers 75 in contact with each other up and down to push the receiving frame 73 installed by itself to move to both sides, and the two sets of inclined tool holders 76 included in the film stripping structure will move along the longitudinal groove of the guiding opposed frame 71. When the receiving frame 73 moves, the film structure will synchronously adjust the thinning distance according to the synchronous transmission component included in the linkage film tearing mechanism 7. The embedded disk 78 included in the film structure is rotatably installed on the outside of the guiding opposed frame 71, and a spiral groove is correspondingly opened on the surface relative to the guiding opposed frame 71, and the clamping rollers 75 installed on the outer ends of the two sets of inclined tool holders 76 are embedded in the spiral groove of the embedded disk 78, so that when the embedded disk 78 rotates, the two sets of inclined tool holders 76 relatively distributed up and down will move along the longitudinal groove of the guiding opposed frame 71. The inclined groove of the acceleration transmission member 712 is displaced inwardly or outwardly at the same time, and the receiving frame 73 is adjusted according to the thickness of the raw material. The traction rack 711 included in the synchronous transmission assembly will follow the displacement of a group of receiving frames 73, and the acceleration transmission member 712 included in the synchronous transmission assembly itself is composed of a group of gear structures and an acceleration pulley structure. The gear structure of the acceleration transmission member 712 is meshed with the traction rack 711 and rotates 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, and the small-diameter wheel output end of the acceleration pulley structure is installed on the rotating shaft of the embedded disk 78, so that the acceleration transmission member 712 accelerates the rotational torque of the gear structure to the embedded disk 78, driving the embedded disk 78 to rotate. The input plate 78 rotates and synchronously drives the two groups of inclined tool holders 76 to move along the longitudinal groove, and the inclined stripping blades 79 tilted and fixed along the inclined tool holder 76 and the inclined guide arc plate 710 suspended on the inclined stripping blade 79 synchronously follow the displacement of the inclined tool holder 76 and contact the surface coating of the sheet raw material. At the same time, the two groups of inclined stripping blades 79 displaced along the inclined angle are synchronously inserted into the coating on the upper and lower surfaces of the sheet raw material, and the inclined guide arc plate 710 suspended on the inclined stripping blade 79 cooperates with the frosted layer added to its own curved structure to rub the coating on the surface of the raw material, driving the coating to loosen and gradually fall off. As the sheet raw material is continuously transported inside the guiding opposing frame 71, the coating on the upper and lower surfaces of the raw material is guided by the inclined stripping blade 79 to be peeled off to the inclined stripping blade. The film is then conveyed into the gap formed between the sheet 79 and the inclined guiding arc plate 710, and is transported along the gap and passes through the through slot provided on the receiving frame 73, so that the SMC sheets of different thicknesses can be automatically guided to tear the film. At the same time, the peeled film will be guided to the upper and lower sides along the through slot of the receiving frame 73 respectively to the two sets of film collecting wheels 8 installed on the working frame 1, and the film collecting wheels 8 will collect the peeled film. The sheet material after the film is torn is guided to the built-in frame 4 along the upper and lower peeled films, and passes through the through hole structure provided on the built-in frame 4 to enter the built-in frame 4, and then contacts the workbench 10 fixed in the built-in frame 4. The workbench 10 is an I-shaped structure, and an opening structure with two side edges distributed is formed between it and the inner wall of the built-in frame 4.The relative cutting mechanism 9 installed in the built-in frame 4 performs quantitative cutting operations on the sheet material that has completed film tearing. The pressing opposite rollers 92 included in the relative cutting mechanism 9 are distributed and installed on the outer wall of the built-in frame 4 facing the linkage film tearing mechanism 7. Before entering the built-in frame 4, the sheet material that has completed film tearing will be clamped and guided by the pressing opposite rollers 92, and then enter the built-in frame 4. The opposite guide rail 91 included in the relative cutting mechanism 9 is installed on the inner wall of the built-in frame 4 close to the pressing opposite rollers 92, and an opposite slide 93 is also installed in a sliding manner relative to each other. At the same time, the opposite slide 93 is at the end The extended tool holders 94 installed at the two ends correspond to each other, and are respectively installed with a segmentation knife 97 for cutting and a linkage cutting table 98 for carrying. When the relative transmission component included in the relative cutting mechanism 9 is started, the linkage rack 911 on one side thereof is pushed, and at the same time drives the central gear 910 installed in the middle of the linkage rack 911 to rotate, while the linkage rack 911 on the other side is driven to rotate by the central gear 910, so that the linkage racks 911 on both sides simultaneously drive a group of extended tool holders 94 to move closer to the inside, and the positioning roller frames 95 installed on the two opposing slides 93 on both sides also move closer accordingly and fit on the original sheet. The sheet is cut on the material, and the segmentation knives 97 respectively installed on the extension knife holders 94 on both sides contact each other with the linkage cutting table 98 to cut and cut the sheet until the segmentation knives 97 are completely immersed in the embedding groove set in the linkage cutting table 98, thereby completing the cutting. When the extension knife holder 94 is driven to retreat, the linkage discharging mechanism 11 installed on the other side of the built-in frame 4 is also opened, and 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, and the downward pressing curved rod 112 included in the linkage discharging mechanism 11 is installed on the extension frame 111 to form a pry bar structure. At the same time, the end of the downward bending rod 112 is a curved structure, and the end of the downward bending rod 112 close to the extension knife frame 94 is connected to the extension knife frame 94 through the traction rod 113. When the relative cutting mechanism 9 completes the cutting and drives the extension knife frame 94 to retreat, it will push the traction rod 113 up, and at the same time drive the downward bending rod 112 to start rotating along the extension frame 111. When the curved structure of the downward bending rod 112 contacts the finished sheet material of the completed structure, it will continue to press down and push the sheet material into the lower part of the internal frame 4 for finished product stacking, so that after the SMC sheet material is cut, the finished product stacking operation can be carried out synchronously.
