Abstract
Description
Technical Field
[0001] This utility model relates to the field of SMC new material manufacturing, specifically to an automated production equipment for SMC new materials. Background Technology
[0002] SMC material, as a high-performance composite material, has advantages such as high strength, corrosion resistance, and high molding efficiency, and is widely used in automotive parts, electrical equipment housings, building structural components, and other fields. During the production of SMC sheets, the edges of the freshly extruded SMC sheets need to be trimmed to ensure that the width meets production requirements, while also meeting the requirement of clean edges to guarantee product dimensional accuracy and appearance quality.
[0003] Currently, the edge cutting methods for SMC sheets are mainly divided into two categories: manual cutting and mechanical cutting. Manual cutting relies on operators using hand tools (such as pneumatic scissors or manual cutters) to cut along the product edge. This method is not only labor-intensive and inefficient, but also susceptible to human error, making it difficult to meet the requirements of high-precision products.
[0004] The scraps cut by existing mechanical shearing devices usually fall directly to the sides of the equipment. Even with collection bins, they can easily fall onto the ground outside the collection bins and into the equipment, requiring manual cleaning and increasing the workload. Utility Model Content
[0005] The purpose of this utility model is to provide an automated production equipment for SMC new materials. This equipment uses a cutting device to cut the front and rear edges of the sheet, reducing the labor intensity of manual labor, improving production efficiency and product accuracy, and uses a collection device to roll up and collect continuous long strips of scrap, reducing the labor intensity of manual cleaning.
[0006] The technical solution adopted by this utility model to solve the above problems is:
[0007] An automated production equipment for SMC new material includes a frame, an extrusion device for SMC sheets, and a winding roller. The winding roller is driven to rotate on the frame by a drive device and is located on the left side of the extrusion device. A cutting device and a collecting device are arranged between the extrusion device and the winding roller. The sheet passes through the cutting device and the cutting device cuts the front and rear edges of the sheet. The collecting device is arranged on the front and rear sides of the cutting device, and the scraps cut from the front and rear edges of the sheet are wound on the collecting device.
[0008] In the above technical solution, preferably, the cutting device includes a drive roller, a driven roller, and a drive motor. The drive roller and the driven roller are rotatably mounted on the frame. The driven roller is mounted on the upper side of the drive roller. The drive roller and the driven roller are provided with two cutting blade groups corresponding to the cutting positions of the front and rear edges of the sheet, respectively. Each cutting blade group includes two cutting blades respectively mounted on the drive roller and the driven roller. The drive motor is mounted on the frame and drives the drive roller to rotate through a gear chain mechanism. The drive roller and the driven roller are respectively fixed with a drive gear and a driven gear, which mesh and drive each other.
[0009] In the above technical solution, preferably, the collecting device is located between the cutting device and the winding roller. The collecting device includes a guide roller and a collecting roller. The guide roller is located on the left side of the cutting device. There are two collecting rollers, which are respectively located on the lower side of the front and rear edges of the sheet. The collecting rollers are rotatably mounted on the frame.
[0010] In the above technical solution, preferably, a connecting shaft is provided between the two collecting rollers, and the front and rear ends of the connecting shaft are coaxially fixed with the two collecting rollers respectively. Two guide rollers are provided, namely a right guide roller and a left guide roller, and the sheet is wound around the right guide roller, the connecting shaft and the left guide roller in sequence.
[0011] In the above technical solution, preferably, the cutter slides back and forth and can be fixedly mounted on the driving roller and the driven roller.
[0012] In the above technical solution, preferably, a ratchet mechanism is provided inside the frame. There are two ratchet mechanisms, which are respectively located at the front and rear ends of the collecting roller. The ratchet mechanism includes a ratchet, a pawl, and a spring. The ratchet is rotatably disposed inside the frame, the pawl is hinged inside the frame, and the spring drives the pawl to lock onto the pawl. The front and rear ends of the collecting roller are inserted and fixed inside the ratchet.
[0013] Compared with the prior art, this utility model has the following advantages and effects:
[0014] This invention produces SMC sheets through an extrusion device, which then passes the sheets through a cutting device. The cutting device cuts the front and rear edges of the sheets, and the cut sheets are wound onto a winding roller. A driving device drives the winding roller to rotate, thereby moving the sheets to the left. This ensures that the width of the sheets meets production requirements and that the front and rear edges are aligned, reducing manual labor intensity and improving production efficiency and product precision. The cut-off scraps are in continuous strips, which are collected by a collection device, reducing the probability of scraps falling to the ground or into the equipment, thus reducing the workload of manual cleaning.

Detailed Implementation
[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0022] See Figures 1-5 This embodiment discloses an automated equipment for producing SMC new materials, including a frame 1, an extrusion device 2 for SMC sheet 6, and a winding roller 3. The winding roller 3 is driven to rotate on the frame 1 by a drive device and is located on the left side of the extrusion device 2. The characteristic feature is that a cutting device 4 and a collecting device 5 are arranged between the extrusion device 2 and the winding roller 3. The sheet 6 passes through the cutting device 4 and the cutting device 4 cuts the front and rear edges of the sheet 6. The collecting device 5 is arranged on the front and rear sides of the cutting device 4, and the scraps cut from the front and rear edges of the sheet 6 are wound on the collecting device 5.
[0023] This invention produces SMC sheet 6 through extrusion device 2, then passes the sheet 6 through cutting device 4. The cutting device 4 cuts the front and rear edges of the sheet 6. The cut sheet 6 is then wound onto winding roller 3. A driving device (e.g., a motor) drives the winding roller 3 to rotate, thereby moving the sheet 6 to the left. This ensures that the width of the sheet 6 meets production requirements and that the front and rear edges of the sheet 6 are aligned, reducing manual labor intensity and improving production efficiency and product precision. The cut-off scraps are in continuous strips. The scraps are collected by winding through collection device 5, reducing the probability of scraps falling to the ground or into the equipment, thus reducing the workload of manual cleaning.
[0024] See Figures 1-3 The cutting device 4 includes a drive roller 41, a driven roller 42, and a drive motor 43. The drive roller 41 and the driven roller 42 are rotatably mounted on the frame 1. The driven roller 42 is mounted on the upper side of the drive roller 41. The drive roller 41 and the driven roller 42 are provided with two cutting blade groups 44, which correspond to the cutting positions of the front and rear edges of the sheet 6, respectively. Each cutting blade group 44 includes two cutting blades 45 respectively mounted on the drive roller 41 and the driven roller 42. The drive motor 43 is mounted on the frame 1 and drives the drive roller 41 to rotate through a gear chain mechanism 46. The drive roller 41 and the driven roller 42 are respectively fixed with a drive gear 47 and a driven gear 48, which mesh and drive each other.
[0025] The sheet 6 is passed through the drive roller 41 and the driven roller 42, with the two cutting blade assemblies 44 positioned at the front and rear edges of the sheet 6 to be cut. When the sheet 6 moves to the left under the action of the winding roller 3, the drive motor 43 drives the drive roller 41 to rotate via the gear chain mechanism 46. Simultaneously, the driven roller 42 is driven to rotate via the meshing action of the drive gear 47 and the driven gear 48, thereby driving the two cutting blade assemblies 44 to rotate. The two cutting blades 45 in each cutting blade assembly 44 rotate in opposite directions and are located on the upper and lower sides of the sheet 6, respectively, to coordinate with the moving direction of the sheet 6 and achieve the purpose of cutting the sheet 6. This cutting device 4 has a simple structure and is easy to maintain.
[0026] See Figure 1 , Figure 2 , Figure 4 The collecting device 5 is located between the cutting device 4 and the winding roller 3. The collecting device 5 includes a guide roller 51 and a collecting roller 52. The guide roller 51 is located on the left side of the cutting device 4. There are two collecting rollers 52, which are located on the lower side of the front and rear edges of the sheet 6 respectively. The collecting rollers 52 are rotatably mounted on the frame 1.
[0027] After being cut by the cutting device 4, the sheet 6 is wound around the guide roller 51. The front and rear scraps are wound downwards through the guide roller 51 onto the front and rear collecting rollers 52, making the structure of the equipment compact and reducing the floor space.
[0028] See Figure 2 , Figure 4 A connecting shaft 53 is provided between the two collecting rollers 52. The front and rear ends of the connecting shaft 53 are coaxially fixed with the two collecting rollers 52 respectively. The guide roller 51 is provided with two guide rollers, namely a right guide roller 54 and a left guide roller 55. The sheet 6 is wound around the right guide roller 54, the connecting shaft 53 and the left guide roller 55 in sequence.
[0029] The right guide roller 54 and the left guide roller 55 can increase the contact area between the sheet 6 and the connecting shaft 53. At the same time, the surface of the connecting shaft 53 can be roughened or coated with a high-friction coefficient coating to increase the friction between the sheet 6 and the connecting shaft 53. When the sheet 6 moves to the left under the action of the winding roller 3, the friction between the sheet 6 and the connecting shaft 53 drives the connecting shaft 53 to rotate, thereby driving the two collecting rollers 52 to rotate, so as to continuously wind the cut-off scraps onto the collecting rollers 52. Therefore, an additional drive device is needed to drive the collecting rollers 52 to rotate, which can reduce the structural complexity of the equipment and ensure that the collecting rollers 52 will only rotate when the sheet 6 moves, reducing the risk of the scraps breaking due to excessive rotation of the collecting rollers 52.
[0030] See Figure 3 The cutter 45 can slide back and forth and can be fixedly mounted on the drive roller 41 and the driven roller 42.
[0031] By adjusting the front and rear positions of the cutter 45, the cutting position of the sheet 6 can be adjusted, thereby enabling the cutting of sheets 6 with different width requirements and improving the applicability of this equipment.
[0032] See Figure 1 , Figure 5 The frame 1 is provided with a ratchet mechanism 7. There are two ratchet mechanisms 7, which are located at the front and rear ends of the collecting roller 52 respectively. The ratchet mechanism 7 includes a ratchet 71, a pawl 72 and a spring 73. The ratchet 71 is rotatably disposed in the frame 1. The pawl 72 is hinged in the frame 1. The spring 73 drives the pawl 72 to be locked on the pawl 72. The front and rear ends of the collecting roller 52 are inserted and fixed in the ratchet 71.
[0033] By restricting the unidirectional rotation of the collecting roller 52 by ratchet 71, the risk of equipment failure caused by the reverse rotation of the collecting roller 52 resulting in the loosening and entanglement of scrap material on the frame 1 or other moving parts is reduced.
[0034] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
