A motor 4 26 is fixedly connected to one side of the lower end surface of the mounting plate 25, and the output end of the motor 4 26 is fixedly connected to the turntable 27.

[0028] Specifically, in the prior art, after the plastic products are formed, they are demoulded so that they fall into a box for collection. Although this method realizes the collection of plastic products and facilitates subsequent transportation, the plastic products collected in this way are placed in the box in a relatively messy state. In some cases, the formed plastic products need to be uniformly packaged or labeled after collection. When the plastic products are in a relatively messy state in the box, it is not conducive to the subsequent processing steps. Therefore, in order to solve the above problem, the working principle of this embodiment is as follows: The plastic product in this embodiment is a plastic bowl, which is a common container. One corner of the box for holding plastic products is fitted with the clamping block 1 30, and then the clamping block 2 31 is driven by the cylinder 3 32 to move until the clamping block 2 31 is fitted with the other corner of the box. The box can be lowered and fixed under the action of the clamping blocks 1 30 and 2 31 to ensure the stability of the box. The two cylinders 43 are used to simultaneously drive the two lower molds 42 to slide until they fit together, and then the hydraulic cylinder 36 is used to drive the upper mold 39 to descend until the upper mold 39 fits together with the lower mold 42. At this time, the upper mold 39 and the two lower molds 42 form a complete molding cavity. At this time, the raw material can be transported to the molding cavity through the discharge pipe 38 and the injection port 49 through the injection cylinder 37; After the plastic product is cooled and formed in the molding cavity, the upper mold 39 is driven to move upward, and at the same time, the two lower molds 42 move away from each other. At this time, the plastic product may adhere to the upper mold 39, so the cylinder 5 47 can be used to drive the connecting block 48 to descend, so that the demoulding rod 46 passes through the upper mold 39 and pushes the plastic product to separate it from the upper mold 39 until the plastic product falls onto the groove on the carrier plate 45, and then repeat the above operation. Whenever a plastic product falls onto the carrier plate 45, the carrier plate 45 will move downward under the action of the guide rail mechanism 5 44. The guide rail mechanism 5 44 is a conventional displacement mechanism and will not be described in detail here; the plastic products can be stacked and placed, and since the plastic product is a plastic bowl, which is arc-shaped, the plastic bowl at the top is embedded in the inner cavity of the plastic bowl below, which is conducive to maintaining stability. When the plastic products on the carrier plate 45 are stacked After a certain number of plastic products are stacked, the carrier plate 45 is driven to move away from the bottom of the lower mold 42 and is located under the mounting plate 25. At this time, the guide rail mechanism 2 can be used to drive the clamping plate 29 to descend again until the bottom of the clamping plate 29 contacts the upper end surface of the carrier plate 45. At this time, multiple stacked plastic products are surrounded by multiple clamping plates 29, and then the motor 26 drives the turntable 27 to rotate to make multiple connecting rods 28 rotate at the same time, so that multiple clamping plates 29 move radially at the same time until all plastic products are clamped. At this time, the guide rail mechanism 2 is used to drive the clamping plate 29 to move into the box body, and the plastic products are placed in the box body, and the plastic products are placed in order along the edge of the box body, and then the above operation is repeated, so that the molded plastic products can be regularly placed in the box body row by row, thereby ensuring the neatness of the plastic products in the box body, which is conducive to subsequent unified packaging or labeling processes.

[0033] Specifically, in the above embodiment, although the plastic products can be neatly placed in the box body by the box loading and moving mechanism, in order to fully utilize the storage space of the box body, the plastic products need to be stacked. When the plastic products stacked in the box body are high and are not blocked on all sides, the plastic products may fall down due to external forces, vibrations, etc., causing the already placed plastic products to become messy again, affecting work efficiency; Therefore, in order to avoid the above problems, when the present embodiment is in use, when the plastic products are placed in the box, the guide rail mechanism 4 7 is used to extend the frame 8 into the box, and according to the width of the box, the motor 5 33 drives the threaded rod 1 34 to rotate, so that the telescopic plate 35 slides on the frame 8 until one side of the frame 8 is in contact with one side of the inner cavity of the box, and then the guide rail mechanism 2 4 is used to drive the partition 6 to move, so that the partition 6 extends into the gap of the frame 8. At this time, the box loading and moving mechanism puts the plastic products into the gap of the frame 8. Since the plastic products are placed along the The plastic products are placed in sequence along the edge of the box, so the plastic products close to the edge of the box will be blocked by the partition 6, the frame 8, and the edge of the box, and the plastic products subsequently placed in the box will be blocked by the plastic products that have been placed, the partition 6, the frame 8, and the telescopic plate 35. When each group of stacked plastic products is placed in the box, there will be an independent placement area and they will always be blocked, thereby avoiding the situation where the plastic products are stacked high and are not blocked on all sides, and they will fall down due to external forces, vibrations, etc., further ensuring the smooth progress of the material transfer work; Although the above method can prevent the plastic products from tipping over when placed in the box, in order to reasonably utilize the box placement space and ensure that adjacent plastic products can support each other, it is necessary to make the adjacent stacked plastic products fit closely. Therefore, this will cause the last group of plastic products placed in each direction to have a gap with the edge of the box, and this gap cannot accommodate another group of plastic products. Therefore, the plastic products may tip over or slide due to this gap during the placement process or subsequent transportation process, causing trouble. Therefore, in order to avoid this situation, the maximum height that plastic products can be placed and the distance between each row of plastic products and the box are determined according to the height, length and width of the box. The size of the gap between the two walls is adjusted by using the guide rail mechanism 3 5 to drive the mounting block 9 to move to the edge of the inner cavity of the box, and drive the rotating plate 11 to drop to a suitable height, then start the motor 3 15 and the motor 6 51 at the same time, and the tape roll 14 unwinds the tape. At the same time, under the action of the gear 22, the two conveying rollers 24 rotate in different directions at the same time to pull the end of the tape. When the end of the tape is at a suitable height, the motor 2 12 drives the threaded rod 3 55 to rotate, so that the attachment roller 54 moves horizontally. The attachment roller 54 first contacts the non-adhesive surface of the tape, and then pushes the end of the tape to press the end of the tape against the inner wall of the box, and the motor 7 52 drives the threaded rod 2 53 to rotate, so that the attachment roller 5 4 moves up and down to firmly attach the end of the tape to one side of the inner wall of the box, and then the guide rail mechanism three 5 drives the rotating plate 11 to move to the other side of the inner wall of the box. At the same time, the tape is also unwinding, and then the cylinder two 20 drives the blade plate 23 to move to cut the tape. At this time, the broken tape will be placed on the attachment roller 54. At this time, the attachment roller 54 is driven to move horizontally to attach the tape on the attachment roller 54 to the inner wall of the box again. At this time, a tape with the same length as the inner wall of the box is attached to the inner wall of the box, and then the motor one 10 drives the rotating plate 11 to rotate ninety degrees, and again a tape with the same width as the inner wall of the box is attached to the inner wall of the box. At this time, the boxing material is transferred by using the box loading method. When the mechanism places plastic products, the uppermost plastic products of the last group of plastic products in each row will be blocked by the tape. Since the uppermost plastic products are blocked, the remaining plastic products are not likely to tip over. When the plastic products in the box are subsequently taken out, the two tapes can be easily removed without affecting the remaining operations. This avoids the situation where, when the plastic products are placed in the box using the box loading and shifting mechanism, there is a gap between the last group of plastic products in each direction and the box, and another group of plastic products cannot be accommodated in the gap, which leads to the tipping and sliding of the plastic products due to the gap during the placement process and subsequent transportation process. This further ensures the stability of the plastic products in the box.

[0034] Working principle: fit one corner of the box for holding plastic products with the clamp block 1 30, and then drive the clamp block 2 31 to move through the cylinder 3 32 until the clamp block 2 31 fits with the other corner of the box, and then the box can be lowered and fixed under the action of the clamp block 1 30 and the clamp block 2 31 to ensure the stability of the box; use two cylinders 43 to simultaneously drive the two lower molds 42 to slide until they fit, and then use the hydraulic cylinder 36 to drive the upper mold 39 to descend until the upper mold 39 fits with the lower mold 42. At this time, the upper mold 39 and the two lower molds 42 form a complete molding cavity. At this time, the raw materials can be transported to the molding cavity through the discharge pipe 38 and the injection port 49 through the injection cylinder 37. cavity; when the plastic product is cooled and formed in the molding cavity, the upper mold 39 is driven to move upward, and at the same time, the two lower molds 42 are moved away from each other. At this time, the plastic product may adhere to the upper mold 39, so the cylinder 5 47 can be used to drive the connecting block 48 to descend, so that the demoulding rod 46 passes through the upper mold 39 and pushes the plastic product to separate it from the upper mold 39 until the plastic product falls to the groove on the carrier plate 45, and then repeat the above operation. Whenever a plastic product falls onto the carrier plate 45, the carrier plate 45 will move downward under the action of the guide rail mechanism 5 44. The guide rail mechanism 5 44 is a conventional displacement mechanism and will not be described in detail here;The plastic products can be stacked and placed, and because the plastic products are plastic bowls, which are arc-shaped, the plastic bowls at the top are embedded in the inner cavity of the plastic bowls at the bottom, which is conducive to maintaining stability. When the plastic products on the carrying plate 45 are stacked to a certain number, the carrying plate 45 is driven to move away from the bottom of the lower mold 42 and is under the mounting plate 25. At this time, the clamping plate 29 can be driven to descend again through the guide rail mechanism 2 until the bottom of the clamping plate 29 contacts the upper end surface of the carrying plate 45. At this time, the multiple stacked plastic products are clamped by the multiple clamping plates 2 9 is surrounded, and then the motor 26 drives the turntable 27 to rotate so that the multiple connecting rods 28 rotate at the same time, and the multiple clamping plates 29 move radially at the same time until all the plastic products are clamped. At this time, the guide rail mechanism 1 2 is used to drive the clamping plates 29 to move into the box body, and the plastic products are placed in the box body. Moreover, the plastic products are placed in order along the edge of the box body, and then the above operation is repeated, so that the formed plastic products can be regularly placed in the box body row by row, thereby ensuring the neatness of the plastic products in the box body, which is conducive to the subsequent processing. When the plastic products are placed in the box, the guide rail mechanism 4 7 is used to extend the frame 8 into the box, and according to the width of the box, the motor 5 33 drives the threaded rod 1 34 to rotate, so that the telescopic plate 35 slides on the frame 8 until one side of the frame 8 fits with one side of the inner cavity of the box, and then the guide rail mechanism 2 4 is used to drive the partition 6 to move, so that the partition 6 extends into the gap of the frame 8. At this time, the box loading and moving mechanism puts the plastic products into the gap of the frame 8. Since the plastic products are along the edge of the box, The plastic products are placed in sequence, so the plastic products near the edge of the box will be blocked by the partition 6, the frame 8, and the edge of the box, and the plastic products placed in the box subsequently will be blocked by the plastic products that have been placed, the partition 6, the frame 8, and the telescopic plate 35. When each group of stacked plastic products is placed in the box, there will be an independent placement area and they will always be blocked, thereby avoiding the situation where the plastic products are stacked high and are not blocked on all sides, and they will fall down due to external forces, vibrations, etc., further ensuring the smooth progress of the material transfer work;Although the above method can prevent the plastic products from tipping over when placed in the box, in order to reasonably utilize the box placement space and ensure that adjacent plastic products can support each other, it is necessary to make the adjacent stacked plastic products fit closely. Therefore, this will cause the last group of plastic products placed in each direction to have a gap with the edge of the box, and this gap cannot accommodate another group of plastic products. Therefore, the plastic products may tip over or slide due to this gap during the placement process or subsequent transportation process, causing trouble. Therefore, in order to avoid this situation, the maximum height that plastic products can be placed and the distance between each row of plastic products and the box are determined according to the height, length and width of the box. The size of the gap between the two walls is adjusted by using the guide rail mechanism 3 5 to drive the mounting block 9 to move to the edge of the inner cavity of the box, and drive the rotating plate 11 to drop to a suitable height, then start the motor 3 15 and the motor 6 51 at the same time, and the tape roll 14 unwinds the tape. At the same time, under the action of the gear 22, the two conveying rollers 24 rotate in different directions at the same time to pull the end of the tape. When the end of the tape is at a suitable height, the motor 2 12 drives the threaded rod 3 55 to rotate, so that the attachment roller 54 moves horizontally. The attachment roller 54 first contacts the non-adhesive surface of the tape, and then pushes the end of the tape to press the end of the tape against the inner wall of the box, and the motor 7 52 drives the threaded rod 2 53 to rotate, so that the attachment roller 5 4 moves up and down to firmly attach the end of the tape to one side of the inner wall of the box, and then the guide rail mechanism three 5 drives the rotating plate 11 to move to the other side of the inner wall of the box. At the same time, the tape is also unwinding, and then the cylinder two 20 drives the blade plate 23 to move to cut the tape. At this time, the broken tape will be placed on the attachment roller 54. At this time, the attachment roller 54 is driven to move horizontally to attach the tape on the attachment roller 54 to the inner wall of the box again. At this time, a tape with the same length as the inner wall of the box is attached to the inner wall of the box, and then the motor one 10 drives the rotating plate 11 to rotate ninety degrees, and again a tape with the same width as the inner wall of the box is attached to the inner wall of the box. At this time, the boxing material is transferred by using the box loading method. When the mechanism places plastic products, the top plastic products of the last group of plastic products in each row will be blocked by the tape. Since the top plastic products are blocked, the remaining plastic products are not easy to fall over. When the plastic products in the box are taken out later, the two tapes can be easily removed without affecting other operations. This avoids the situation where the last group of plastic products in each direction has a gap with the box when the box is placed in the box by using the box loading and material transfer mechanism, and another group of plastic products cannot be accommodated in the gap, which leads to the plastic products falling or sliding due to the gap during the placement process and subsequent transportation process. This further ensures the stability of the plastic products in the box. ;
