Description

Technical Field

[0002] As a new molding material, SMC sheet has the following advantages: good reproducibility, not affected by the operator and the environment, convenient and easy to operate; good fluidity, can be formed into special-shaped products, good quality uniformity, suitable for pressing large thin-walled products with little cross-sectional variation; high production efficiency, short molding cycle, easy to realize fully automatic mechanized operation, low production cost; good electrical properties and insulation properties, etc. Therefore, SMC sheet is widely used in modern construction, industry, electronic and electrical industries and other fields.

[0003] Before the SMC molding plastic sheet is molded, the upper and lower surfaces of the sheet need to be cleaned to ensure that the surface of the sheet is well tidy and to avoid contamination and damage to the surface by impurities, which may affect the subsequent molding. In the process of cleaning the sheet, since the sheet is soft, it needs to be laid on the platform for single-side cleaning, and then the sheet is turned over and the other side is cleaned. After the sheet is cleaned, it is transported to the molding machine for processing without stopping. Here, a sheet turning and conveying device is required. However, in the actual turning process, the existing sheet turning and conveying device often uses a suction cup assembly to absorb the sheet on the conveying platform and then turns it over to the transition platform. , then the other side is cleaned on the transition platform, and then the sheet is sucked and transferred to the conveying platform by the suction cup assembly. This method increases the flipping process, increases the overall conveying time, and also causes a certain amount of transfer steps between the conveying platform and the flushing transition platform, which causes the overall conveying process to be interrupted, affecting the conveying continuity and efficiency of the conveying platform; at the same time, due to the existence of the transfer step, the placement of the sheet may be offset, and after being placed on the conveying platform again, an additional position adjustment step is required to align the sheet with the original conveying direction, further increasing the flipping conveying process, thereby further extending the time of the process, that is, further reducing the conveying efficiency.

[0024] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0025] The utility model provides Figure 1-3 The SMC molding compound sheet flipping and conveying device shown comprises two symmetrically arranged positioning rings 1, a first conveyor belt 13 arranged between the left sides of the two positioning rings 1, and a second conveyor belt 20 arranged between the right sides of the two positioning rings 1, a connecting plate 5 which can rotate forward or reverse 180 degrees is rotatably arranged in the positioning ring 1, a flip plate 6 which can be detachably connected between the top sides and the bottom sides of the two connecting plates 5, a plurality of conveying rollers 10 which can transfer the SMC sheet from one side to the other side are detachably rotatably arranged in the flip plate 6, and the two conveying rollers 10 located at the leftmost and rightmost ends of the flip plate 6 can be actively rotated, two side limit plates 12 are relatively slidably arranged at the lower part between the two flip plates 6, and the two side limit plates 12 can synchronously slide the same distance in the direction close to or away from the middle of the flip plate 6, the two conveying rollers 10 at the leftmost end and the two conveying rollers 10 at the rightmost end can both be actively rotated, so that flipping transmission from the first conveyor belt 13 to the second conveyor belt 20 and from the second conveyor belt 20 to the first conveyor belt 13 can be realized, that is, flipping transmission in two directions can be realized.

[0026] An empty slot 7 is provided in the flip plate 6, and multiple conveying rollers 10 can be detachably and rotatably arranged in the empty slot 7. Both sides of the flip plate 6 with the empty slot 7 and the connecting plate 5 that are detachably connected are provided with multiple card slots 8 that are the same number as the conveying rollers 10. A rotating rod 9 is detachably connected between two card slots 8 located on different sides of the flip plate 6 and in the same straight line. The conveying rollers 10 are detachably sleeved on the rotating rod 9. The conveying rollers 10 located at the leftmost and rightmost ends and the other conveying rollers 10 do not have the function of active rotation. However, after the sheet enters the two flip plates 6, the rotating driving force of the actively rotatable conveying rollers 10 can drive the other conveying rollers 10 to rotate, thereby completing the step of sliding the sheet from one side to the other side.

[0027] An annular slide rail 2 is detachably installed on the inner side wall of the positioning ring 1, and slide seats 4 are connected to both ends of the connecting plate 5. The two slide seats 4 are slidably connected to the annular slide rail 2. The ends of the two positioning rings 1 that are away from each other are connected to the outer positioning plate 3. The center of the side wall of the two outer positioning plates 3 that are away from each other can be detachably installed with a first motor 14. The output end of the first motor 14 is rotatably provided with a first rotating shaft 15 that can rotatably pass through the outer positioning plate 3. The other end of the first rotating shaft 15 is detachably connected to the center of the connecting plate 5. The first motor 14 can drive the connecting plate 5 to rotate forward or reverse 180 degrees. The first motor 14 rotates, thereby driving the connecting plate 5 to rotate in the positioning ring 1. During the process, the two slide seats 4 on both sides slide along the annular slide rail 2, thereby ensuring that the connecting plate 5 is in a concentric rotation state while ensuring the rotation stability of the connecting plate 5 and the flip plate 6, thereby avoiding flipping and deviation.

[0028] One of the connecting plates 5 is adapted to be located at the positions of the two conveying rollers 10 at the leftmost and rightmost ends of the flip plate 6, and an active groove 21 with the same size as the card slot 8 is opened. One of the side walls of the outer positioning plates 3 is adapted to be located at the position of each active groove 21 and a second motor 16 can be detachably installed.

The side walls of the two outer positioning plates 3 close to each other can be detachably installed with a telescopic component 18, and the other end of the telescopic component 18 is detachably connected to the movable frame 11. According to the width of the sheet, the telescopic component 18 actively retracts and contracts, so that the two side limit plates 12 can slide synchronously close to each other in the two flip plates 6 until they respectively abut against the two side edges of the sheet, thereby ensuring the limitation of the sheet.

[0030] Extension plates 19 are detachably installed on the left and right sides of the outer peripheral side walls of the two positioning rings 1. The first conveyor belt 13 is rotatably set between the two extension plates 19 on the left, and the second conveyor belt 20 is rotatably set between the two extension plates 19 on the right.

[0031] In the present invention, the sheet is first cleaned on one side on the first conveyor belt 13, and then the flip plate 6 is flipped so that when passing through the second conveyor belt 20, the other side of the sheet faces upward, thereby completing the cleaning of the other side on the second conveyor belt 20. In this process, the first conveyor belt 13 and the second conveyor belt 20 run uninterruptedly, thereby ensuring the continuity of flipping, conveying and cleaning; and in the specific flipping process, the two conveying rollers 10 at the leftmost end rotate autonomously, thereby transferring the sheet on the first conveyor belt 13 to the two flip plates 6 through the rotational driving force, and with the auxiliary rotation of multiple conveying rollers 10 inside the flip plate 6, the sheet is transferred from left to right. When the sheet completely enters the flip plate 6, the connecting plate 5 is driven to rotate forward or reverse 180 degrees, thereby driving the two flip plates 6 and the sheet inside to complete a 180-degree flip. At this time, the two autonomously rotatable conveying rollers 10 originally located at the leftmost end It switches to the rightmost end, and then, under the rotational driving force of the conveying roller 10 and the conveying traction of the second conveyor belt 20, the sheet gradually slides from between the two flip plates 6 to the second conveyor belt 20, and during the flipping process, the spacing between the two side limit plates 12 can be changed according to the width of the sheet so that they are respectively in contact with the two side edges of the sheet, thereby ensuring that the original transmission direction remains unchanged during the flipping of the sheet, that is, the sheet after entering the second conveyor belt 20 maintains the same transmission direction as on the first conveyor belt 13, avoiding the need to set up an additional mechanism to complete the adjustment of the transmission direction, and compared with the suction cup adsorption and transfer method, the overall flipping and conveying process is reduced, and during the conveying process, the flipping of the flip plate 6 and the conveying of the first conveyor belt 13 and the second conveyor belt 20 do not affect each other, thereby achieving the continuity of flipping, conveying and cleaning, and ultimately improving the overall flipping and conveying efficiency while reducing the conveying time.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
