Description

Technical Field

[0001] The present invention belongs to the technical field of plastic molding, and specifically relates to a plastic product processing and molding device. Background Art

[0002] Plastic products are general terms for daily necessities, industrial products, etc. mainly processed from plastics. When producing plastic products, the injection molding method is usually adopted. By adding molten plastic raw materials into the mold, the required shape is formed after cooling and solidification in the mold.

[0003] The patent with the publication number CN208881118U discloses a plastic product molding device, including a plastic mold and an injection molding facility. The plastic mold includes a mold frame, a moving mold, and a fixed mold. One side bottom of the moving mold is rotatably connected to a rotating block through a hinge. One side of the rotating block is rotatably connected to one side of a telescopic rod. The center of one side of the moving mold is fixedly connected to an internal threaded rod, and the internal threaded rod is rotatably connected to a first motor through a bolt. One side of the injection molding facility is provided with a melting tube. One side of the melting tube is spirally connected to an injection molding screw, and the surface of one side of the injection molding screw is fixedly connected to the main shaft of a second motor. In this patent: First, by using the first motor and the second motor, the production cost is reduced while the floor area of the entire device is reduced. Second, a telescopic rod and a rotating block are provided between the mold bracket and the rotating block, and the plastic product can be put down when the compression rod is compressed to the bottom, thus avoiding material jamming caused by incomplete demolding.

[0004] However, the above technical solution still has the following deficiencies in actual application:

[0005] When the plastic product is molded, although the ejection structure can be used to demold the plastic product, in some cases, in order to improve the molding efficiency, different color plastic raw materials are simultaneously injected into multiple molds with the same specifications at one time to achieve the purpose of simultaneously molding multiple plastic products of different colors. And, in order to facilitate the subsequent packaging of multiple molded plastic products, the multiple molded plastic products need to be arranged and placed in a fixed order, and then transported to the packaging process by a conveying mechanism for packaging. After the plastic product is demolded by the ejection structure, it is also necessary to manually sort the plastic products of different colors and place them on the conveying mechanism. The whole process is relatively cumbersome and prone to sorting errors. Summary of the Invention

[0022] 1.

When the push plate moves in the inner cavity of the mold, the formed plastic product can be pushed out, thus realizing the automatic demolding of the formed plastic product, which is relatively convenient.

[0023] 2. The plastic product processing and forming device described in the present invention utilizes a sorting and feeding mechanism. After plastic products of multiple different colors are formed, they can be arranged and placed on the receiving plate in a preset order, and then uniformly transferred to the conveying mechanism after arrangement. The conveying mechanism then transports the plastic products into the packaging process for packaging. This eliminates the process of workers manually arranging the demolded plastic products, saving effort, facilitating the improvement of the subsequent packaging efficiency of plastic products, and avoiding sorting errors caused by manual sorting. Moreover, with the use of the conveying component, after the plastic products are pushed onto the receiving plate, the conveyor belt drives the plastic products to move until they are in contact with each other, preventing the situation where when the plastic products move onto the receiving plate, they get stuck during the sliding process due to the large frictional force between the plastic products and the receiving plate and cannot slide down normally. This not only makes reasonable use of the placement space of the receiving plate, but also after the plastic products are transferred to the conveying mechanism, adjacent plastic products are closely attached, which is conducive to improving the subsequent packaging efficiency of plastic products. Additionally, when a batch of plastic products are all arranged on the receiving plate, the pushing angle plate can continuously push the multiple plastic products, and with the cooperation of the infrared emitter, the end faces of adjacent plastic products on the receiving plate are in a fitting state, preventing the situation where when the plastic products slide onto the receiving plate, due to the corners and end faces of adjacent plastic products being in contact, the clamping plate one and the clamping plate two cannot normally pick up the multiple plastic products when clamping them. Moreover, the multiple plastic products have the same orientation, which is conducive to subsequent unified packaging. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The sorting and receiving mechanism includes a receiving plate 18 fixedly connected to one side of the upper end surface of the bottom plate 1, two connecting rods 2 are rotatably arranged on both sides of the right end of the bottom plate 1, a displacement plate 4 is rotatably arranged on the upper end of the connecting rod 2, two sliding rods 10 are slidably connected on the displacement plate 4, a lifting block 11 is fixedly connected to the lower end of the sliding rod 10, an adjusting plate 13 is rotatably arranged on the lower end of the lifting block 11, sliding rods 16 are fixedly connected on both sides of the adjusting plate 13, and clamping plates 17 and 22 are respectively fixedly connected on both sides of the sliding rod 16.

[0038] In this embodiment, as Figure 1 、 Figure 4 、 Figure 5 、 Figure 9 shown, a support platform 8 is fixedly connected to the upper end surface of the turntable 6, a plurality of raw material boxes 7 are fixedly connected to the upper end surface of the support platform 8, a feeding pipe 30 communicates with one side of the raw material box 7, and one end of the feeding pipe 30 communicates with the inner cavity of the mold 49.

[0039] A gear 40 is rotatably arranged on one side of the workbench 5, and the gear 40 meshes with the tooth blocks on the outer ring of the turntable 6. A seventh motor 39 is fixedly connected to one side of the workbench 5, and the output end of the seventh motor 39 is fixedly connected to the gear 40.

[0040] A sixth motor 28 is fixedly connected to one side of the upper end surface of the mold 49, and a third threaded rod 29 is fixedly connected to the output end of the sixth motor 28. The third threaded rod 29 is threadedly connected to one side of the cover plate 27.

[0041] Two third slide bars 33 are fixedly connected to one side of the push plate 31. The third slide bars 33 are slidably connected to the mold 49. One end of the third slide bars 33 is fixedly connected to a connecting block 32. A fixing plate 35 is fixedly connected to one side of the workbench 5. Two fourth slide bars 37 are slidably connected to one side of the upper end of the fixing plate 35. One end of the fourth slide bars 37 is fixedly connected to a pushing block 38. A second electric push rod 36 is fixedly connected to one side of the upper end of the fixing plate 35.

[0042] Specifically, in the initial state, the cover plate 27 covers the inner cavity of the mold 49, and the push plate 31 is located at the edge of the inner cavity of the mold 49. At this time, the cover plate 27, the push plate 31, and the mold 49 form a complete molding cavity, and the molding cavity is a cube, and the molded plastic product is also a cube. Then, the raw material box 7 transports the injection molding raw materials to the molding cavity through the feeding pipe 30. When the raw materials are cooled and molded in the molding cavity, the cover plate 27 is lifted by driving the third threaded rod 29 to rotate by the sixth motor 28, so that the molded plastic product is no longer covered. At this time, the turntable 6 can be rotated by driving the gear 40 to rotate by the seventh motor 39 until the connecting block 32 is aligned with the pushing block 38. By driving the pushing block 38 to move by the second electric push rod 36, the pushing block 38 squeezes the connecting block 32, so that the third slide bars 33 and the push plate 31 can move simultaneously. When the push plate 31 moves in the inner cavity of the mold 49, the molded plastic product can be pushed out, thus realizing the automatic demolding of the molded plastic product, which is relatively convenient.

[0043] In this embodiment, as Figures 1 - 3 、 Figures 6 - 8As shown, on one side of the upper end surface of the bottom plate 1, a first motor 3 is fixedly connected. The output end of the first motor 3 is fixedly connected to one end of a first connecting rod 2. On one side of the upper end surface of the displacement plate 4, a first electric push rod 9 is fixedly connected.

On one side of the adjusting plate 13, a third motor 14 is fixedly connected. The output end of the third motor 14 is fixedly connected to one end of the bidirectional threaded rod 15.

[0045] On the first clamping plate 17, an adjustable detection mechanism is also provided for judging whether the end faces of multiple plastic products on the receiving plate 18 are in contact.

[0046] The adjustable detection mechanism includes a first slider 20 slidably connected to one side of the first clamping plate 17. On one side of the first slider 20, an infrared emitter 48 is provided. On one side of the first slider 20, a first threaded rod 19 is threadedly connected. Both ends of the first threaded rod 19 are rotatably arranged on the first clamping plate 17. One end of the first clamping plate 17 is fixedly connected to a fourth motor 21. The output end of the fourth motor 21 is fixedly connected to one end of the first threaded rod 19.

[0047] On the second clamping plate 22, a sliding type angle pushing assembly is also provided for making multiple plastic products on the receiving plate 18 face in the same direction.

[0048] The sliding type angle pushing assembly includes a second slider 43 slidably connected to one side of the second clamping plate 22. On one side of the second slider 43, an angle pushing plate 47 is inserted and slidably connected. On one side of the second clamping plate 22, a groove 41 is provided. The second clamping plate 22 can pass through the groove and contact the plastic product. On one side of the second slider 43, a second threaded rod 26 is threadedly connected. Both ends of the second threaded rod 26 are rotatably arranged on the second clamping plate 22. One end of the second clamping plate 22 is fixedly connected to an eighth motor 42. The output end of the eighth motor 42 is fixedly connected to one end of the second threaded rod 26. On one side of the second slider 43, a second connecting rod 45 is rotatably arranged. One end of the second connecting rod 45 is rotatably arranged with a third connecting rod 46. One end of the third connecting rod 46 is rotatably connected to one side of the angle pushing plate 47. On one side of the second slider 43, a ninth motor 44 is fixedly connected. The output end of the ninth motor 44 is fixedly connected to one end of the second connecting rod 45.

[0049] On the receiving plate 18, a conveying assembly is also provided.

[0050] The conveying assembly includes rotating rollers 24 rotatably arranged on both sides of the receiving plate 18. On the rotating rollers 24, a conveyor belt 25 is provided. On one side of the receiving plate 18, a fifth motor 23 is fixedly connected. The output end of the fifth motor 23 is fixedly connected to the rotating roller 24.

[0051] Specifically, in the prior art, after the plastic product is molded, although the ejection structure can be used to demold the plastic product, in some cases, in order to improve the molding efficiency, different colored plastic raw materials are simultaneously injected into multiple molds 49 of the same specification at one time to achieve the purpose of simultaneously molding multiple plastic products of different colors. Moreover, in order to facilitate the subsequent packaging of multiple molded plastic products, the multiple molded plastic products need to be arranged and placed in a fixed order, and then conveyed to the packaging process by a conveying mechanism for packaging. After the plastic product is demolded by the ejection structure, it is also necessary for workers to manually sort the plastic products of different colors and place them on the conveying mechanism. The whole process is relatively cumbersome and prone to sorting errors;

[0052] Therefore, to solve the above problems, when this embodiment is in use, the bottom plate 1 is placed beside the conveying mechanism for conveying the arranged plastic products, and then different colored injection molding raw materials are added into different raw material boxes 7 respectively, and the different colored injection molding raw materials enter different molds 49 at the same time. When the injection molding raw materials in all the molds 49 are cooled and molded, the turntable 6 is driven to rotate. Whenever a mold 49 is aligned with the receiving plate 18, the cover plate 27 is driven to move upward, and then the push plate 31 is driven to move to push out the molded plastic product. The plastic product then moves onto the receiving plate 18 and slides down along with the receiving plate 18. By controlling the rotation of the turntable 6, multiple plastic products can be arranged and placed on the receiving plate 18 in a preset order. After the arrangement is completed, the first clamping plate 17 and the second clamping plate 22 are driven to approach each other by rotating the bidirectional threaded rod 15 driven by the third motor 14, clamping the multiple plastic products on the receiving plate 18. Then, the first motor 3 drives the first connecting rod 2 to rotate, causing the displacement plate 4 to move until the displacement plate 4 is above the conveying mechanism and the multiple plastic products are also above the conveying mechanism. Then, the second motor 12 is used to drive the adjusting plate 13 to rotate, so that the bottoms of the multiple plastic products are parallel to the upper part of the conveying mechanism. Then, the first electric push rod 9 is used to drive the lifting block 11 to descend, accurately placing the plastic products at the designated position of the conveying mechanism. Then, the first clamping plate 17 and the second clamping plate 22 are driven to release the plastic products, allowing the plastic products to enter the next process for packaging along with the conveying mechanism. Thus, after multiple plastic products of different colors are molded, they can be arranged and placed in a preset order, and can be uniformly transferred to the conveying mechanism after the arrangement. The conveying mechanism then takes the plastic products into the packaging process for packaging, thereby saving the process of workers manually arranging the demolded plastic products, being relatively labor-saving, facilitating improving the subsequent packaging efficiency of the plastic products, and also avoiding sorting errors caused by manual sorting;

[0053] Although the automatic sorting of multiple plastic products can be achieved through the above method, since each plastic product after demolding slides down along the receiving plate 18, when the friction between the plastic product and the receiving plate 18 is large, the plastic product may get stuck during the sliding process, resulting in an inability to fall normally and a gap between the plastic products. This not only fails to make reasonable use of the placement space of the receiving plate 18 but also causes a gap between the plastic products transferred to the conveying mechanism, affecting the subsequent packaging efficiency. Therefore, to avoid this situation, after the plastic product is pushed onto the receiving plate 18, the motor five 23 drives the rotating roller 24 on one side to rotate, and under the action of the rotating roller 24 on the other side, the conveyor belt 25 operates. The conveyor belt 25 can drive the plastic product to move until the plastic products are in contact with each other. Moreover, the plastic products that have already been in contact with each other will not move under the action of the conveyor belt 25. This avoids the situation where, when the plastic product moves onto the receiving plate 18, due to the large friction between the plastic product and the receiving plate 18, the plastic product gets stuck during the sliding process and cannot slide down normally. This not only makes reasonable use of the placement space of the receiving plate 18 but also ensures that the adjacent plastic products are closely attached after being transferred to the conveying mechanism, which is beneficial to improving the subsequent packaging efficiency of the plastic products;

[0054] Although the adjacent plastic products on the receiving plate 18 can be closely fitted in the above manner, since the plastic products are cubes, when the plastic products slide onto the receiving plate 18, it is possible that the adjacent plastic products are not fitted by their end faces, but by their edges and end faces. This will not only cause the situation that when the clamping plate one 17 and the clamping plate two 22 clamp the plastic products, they cannot pick up multiple plastic products normally because the clamping plate one 17 and the clamping plate two 22 are fitted with the edges of the plastic products, but also cause the situation that the subsequent packaging is affected due to the different orientations of the plastic products. Therefore, to avoid this problem, after a batch of plastic products are arranged on the receiving plate 18, according to the total number of plastic products on the receiving plate 18, the standard length when the end faces of multiple plastic products are mutually fitted can be obtained. If the end faces of two adjacent plastic products are not fitted, the standard length will increase. Because the diagonal length of a square is greater than the side length, according to the standard length when the end faces of multiple plastic products are mutually fitted, by the way of driving the threaded rod one 19 to rotate by the motor four 21, the slider one 20 slides on the clamping plate one 17 until the distance between the emitting end of the infrared emitter 48 and the end face of the lowermost plastic product exceeds the standard length and is within a reasonable range. At this time, the infrared emitter 48 emits infrared rays. If no plastic product is detected, it means that the end faces of the plastic products are mutually fitted. If a plastic product is detected, it means that the length formed by multiple plastic products exceeds the standard length. At this time, the motor eight 42 drives the threaded rod two 26 to rotate, so that the slider two 43 slides on the clamping plate two 22, and the angle-pushing plate 47 starts to move from the starting position of the standard length. Whenever the angle-pushing plate 47 moves a length equal to the side length of a plastic product, the slider two 43 stops moving. The motor nine 44 drives the connecting rod two 45 and the connecting rod three 46 to rotate, so that the angle-pushing plate 47 slides on the slider two 43 and passes through the groove 41 to contact the plastic product. If the end faces of two adjacent plastic products are not fitted, the plastic product will deflect due to the edge being pushed. When the angle-pushing plate 47 moves to the end of the clamping plate two 22, at this time, by using the infrared emitter 48 again, if a plastic product is still detected, it still means that the end faces of adjacent plastic products are not fitted. Then the angle-pushing plate 47 repeats the work until the infrared emitter 48 cannot detect a plastic product. At this time, the end faces of adjacent plastic products on the receiving plate 18 are all in a fitted state. Then the clamping plate one 17 and the clamping plate two 22 can be used to transfer the plastic products, thus avoiding the situation that when the plastic products slide onto the receiving plate 18, they cannot pick up multiple plastic products normally because the edges and end faces of adjacent plastic products are fitted. Moreover, the orientations of multiple plastic products are the same, which is beneficial to subsequent unified packaging.

[0055] Working principle: In the initial state, the cover plate 27 covers the inner cavity of the mold 49, and the push plate 31 is at the edge of the inner cavity of the mold 49. At this time, the cover plate 27, the push plate 31, and the mold 49 form a complete molding cavity, and the molding cavity is a cube, and the molded plastic product is also a cube. Then, the raw material box 7 transports the injection molding raw materials to the molding cavity through the feeding pipe 30. When the raw materials are cooled and molded in the molding cavity, the cover plate 27 is lifted by driving the rotation of the threaded rod three 29 by the motor six 28, so that the molded plastic product is no longer covered. At this time, the turntable 6 can be rotated by driving the rotation of the gear 40 by the motor seven 39 until the connecting block 32 is aligned with the push block 38. By driving the movement of the push block 38 by the electric push rod two 36, the push block 38 can be made to squeeze the connecting block 32, so that the slide rod three 33 and the push plate 31 can move simultaneously. When the push plate 31 moves in the inner cavity of the mold 49, the molded plastic product can be pushed out, thus realizing the automatic demolding of the molded plastic product, which is relatively convenient. Place the bottom plate 1 beside the conveying mechanism for conveying the arranged plastic products, and then add injection molding raw materials of different colors into different raw material boxes 7 respectively, and the injection molding raw materials of different colors enter different molds 49 at the same time. When the injection molding raw materials in all molds 49 are cooled and molded, drive the turntable 6 to rotate. Whenever a mold 49 is aligned with the receiving plate 18, drive the cover plate 27 to move upward, and then drive the push plate 31 to move to push out the molded plastic product. The plastic product then moves onto the receiving plate 18 and slides down along with the receiving plate 18. By controlling the rotation of the turntable 6, multiple plastic products can be arranged and placed on the receiving plate 18 in a preset order. After the arrangement is completed, drive the rotation of the bidirectional threaded rod 15 by the motor three 14 to make the clamping plate one 17 and the clamping plate two 22 approach each other and clamp the multiple plastic products on the receiving plate 18. Then, drive the rotation of the connecting rod one 2 by the motor one 3 to make the displacement plate 4 move until the displacement plate 4 is above the conveying mechanism and the multiple plastic products are also above the conveying mechanism. Then, drive the rotation of the adjusting plate 13 by the motor two 12 to make the bottoms of the multiple plastic products parallel to the upper part of the conveying mechanism. Then, drive the lifting block 11 to descend by the electric push rod one 9 to accurately place the plastic products at the designated position of the conveying mechanism. Then, drive the clamping plate one 17 and the clamping plate two 22 to release the plastic products, so that the plastic products enter the next process for packaging along with the conveying mechanism. Therefore, after multiple plastic products of different colors are molded, they can be arranged and placed in a preset order, and can be uniformly transferred to the conveying mechanism after the arrangement, and the conveying mechanism can bring the plastic products into the packaging process for packaging, thus saving the process of manually arranging the demolded plastic products by workers, being relatively labor-saving, being beneficial to improving the subsequent packaging efficiency of plastic products, and also avoiding the situation of sorting errors due to manual sorting;Although the automatic sorting of multiple plastic products can be achieved through the above method, since each plastic product after demolding slides down along the receiving plate 18, when the friction between the plastic product and the receiving plate 18 is large, the plastic product may get stuck during the sliding process, resulting in an inability to fall normally and a gap between the plastic products. This not only fails to make reasonable use of the placement space of the receiving plate 18 but also causes a gap between the plastic products transferred to the conveying mechanism, affecting the subsequent packaging efficiency. Therefore, to avoid this situation, after the plastic product is pushed onto the receiving plate 18, the motor five 23 drives the rotating roller 24 on one side to rotate, and under the action of the rotating roller 24 on the other side, the conveyor belt 25 operates. The conveyor belt 25 can drive the plastic product to move until the plastic products are in contact with each other. Moreover, the plastic products that have already been in contact with each other will not move under the action of the conveyor belt 25. Thus, when the plastic product moves onto the receiving plate 18, it can be avoided that due to the large friction between the plastic product and the receiving plate 18, the plastic product gets stuck during the sliding process and cannot slide down normally. This not only makes reasonable use of the placement space of the receiving plate 18 but also when the plastic product is transferred to the conveying mechanism, adjacent plastic products are closely attached to each other, which is beneficial to improving the subsequent packaging efficiency of the plastic product;Although the adjacent plastic products on the receiving plate 18 can be closely fitted in the above manner, since the plastic products are cubes, when the plastic products slide onto the receiving plate 18, it is possible that the adjacent plastic products are not fitted with their end faces, but with their edges and end faces. This will not only cause the situation that when the clamping plate one 17 and the clamping plate two 22 clamp the plastic products, because the clamping plate one 17 and the clamping plate two 22 are fitted with the edges of the plastic products, the multiple plastic products cannot be normally picked up, but also cause the situation that the subsequent packaging is affected due to the different orientations of the plastic products. Therefore, to avoid this problem, after a batch of plastic products are arranged on the receiving plate 18, according to the total number of plastic products on the receiving plate 18, the standard length when the end faces of the multiple plastic products are mutually fitted can be obtained. If the end faces of two adjacent plastic products are not fitted, the standard length will increase. Because the diagonal length of a square is greater than the side length, according to the standard length when the end faces of the multiple plastic products are mutually fitted, by driving the rotation of the threaded rod one 19 by the motor four 21, the slider one 20 slides on the clamping plate one 17 until the distance between the emitting end of the infrared emitter 48 and the end face of the lowermost plastic product exceeds the standard length and is within a reasonable range. At this time, the infrared emitter 48 emits infrared rays. If no plastic product is detected, it means that the end faces of the plastic products are mutually fitted. If a plastic product is detected, it means that the length formed by the multiple plastic products exceeds the standard length. At this time, the motor eight 42 drives the rotation of the threaded rod two 26, so that the slider two 43 slides on the clamping plate two 22, and the angle-pushing plate 47 starts to move from the starting position of the standard length. Whenever the angle-pushing plate 47 moves a length equal to the side length of a plastic product, the slider two 43 stops moving. The motor nine 44 drives the rotation of the connecting rod two 45 and the connecting rod three 46, so that the angle-pushing plate 47 slides on the slider two 43 and passes through the groove 41 to contact the plastic product. If the end faces of two adjacent plastic products are not fitted, the plastic product will deflect due to the pushing of the edge. When the angle-pushing plate 47 moves to the end of the clamping plate two 22, at this time, by using the infrared emitter 48 again, if a plastic product is still detected, it still means that the end faces of adjacent plastic products are not fitted. Then the angle-pushing plate 47 repeats the work until no plastic product is detected by the infrared emitter 48. At this time, the end faces of the adjacent plastic products on the receiving plate 18 are all in a fitted state. Then the clamping plate one 17 and the clamping plate two 22 can be used to transfer the plastic products, thus avoiding the situation that when the plastic products slide onto the receiving plate 18, because the edges and end faces of the adjacent plastic products are fitted, the clamping plate one 17 and the clamping plate two 22 cannot normally pick up the multiple plastic products when clamping the plastic products. Moreover, the multiple plastic products have the same orientation, which is beneficial to subsequent unified packaging.
