Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of plastic product processing, and more specifically, to a molding and processing production line for plastic products. Background Art
[0002] Plastic is a high molecular compound made from monomers through addition polymerization or condensation polymerization. It is commonly known as plastic or resin. It can freely change its composition and shape. It is composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. Plastic has the advantages of good plasticity and moderate strength. In industrial production, it is often necessary to use certain devices (usually injection molds) to make plastic products to replace metal products.
[0003] The molding and processing production line of plastic products includes raw material preparation, melting and plasticizing, molding, cooling and solidification, demolding, post-processing and packaging for delivery. Among them, after injection molding, plastic products are mostly unloaded by robotic arms. When mechanical equipment is used to palletize injection molded plastic products, the heat of the newly injected plastic products has not been completely dissipated. When stacking plastic products, they need to wait for cooling to avoid deformation between plastic products due to bonding. However, in the process of waiting for cooling, not only the production efficiency of injection molded plastic products is affected, but also some plastic products will have more burrs at the corners after injection molding, which affects the palletizing effect of plastic products.

[0034] The working body 1 includes a fixed box body 11, an air inlet 12 is provided on one side of the upper end of the fixed box body 11, a material guide chute 13 is provided on the top side of the fixed box body 11 near the air inlet 12, a first lifting hydraulic cylinder 17 is fixedly installed on the bottom end of the air inlet 12, a lifting box 18 is provided on the top of the first lifting hydraulic cylinder 17, the lifting box 18 is slidably installed in the fixed box body 11, a connecting groove 19 is provided on one side of the lifting box 18, the connecting groove 19 corresponds to one side of the air inlet 12, an air outlet groove 111 is provided on the top of the lifting box 18, and the lifting box 18 is provided with a lifting groove 111. A placing frame 110 is movably installed on the top, and a rotating block is fixedly installed on the bottom of the placing frame 110. The rotating block is rotatably installed on the top of the lifting box 18. A fixed plate 14 is fixedly installed on the side of the fixed box 11 away from the conveyor belt 2. The bottom of the fixed plate 14 is located on the side of the fixed box 11 where a pushing cylinder 15 is fixedly installed. A pushing plate 16 is provided on one side of the pushing cylinder 15. The pushing plate 16 is embedded and installed on one side of the inner wall of the fixed box 11. A discharge port 112 is opened on the side of the fixed box 11 away from the pushing cylinder 15. The discharge port 112 is located at one end of the conveyor belt 2.
[0035] During operation, the first lifting hydraulic cylinder 17 extends to push the lifting box 18 up, and the lifting box 18 rises to the upper end of the fixed box body 11, and the placement shelf 110 is located on the top of the fixed box body 11. At the same time, one side of the lifting box 18 corresponds to the air inlet 12 and is located on one side of the semiconductor refrigeration plate 56. At this time, the fan assembly 55 works, and air will enter the interior of the feed box 51 through the dust suction air port 52, and generate cold air through heat exchange of the semiconductor refrigeration plate 56. The cold air passes through the air outlet slot 111 to cool the plastic products on the placement shelf 110.
[0036] Among them, the cooling component 5 includes a feed box 51, a dust suction vent 52 is opened on one side of the top of the feed box 51, a waste box 57 is movably connected to one side of the bottom of the feed box 51, the feed box 51 is fixedly installed on one side of the upper end of the fixed box body 11, the feed box 51 is fixedly installed on the top of the fixed plate 14, the material guide chute 13 is located on one side of the dust suction vent 52, a fixed cover 53 is fixedly connected to one side of the feed box 51, the fixed cover 53 is fixedly connected to the inside of the air inlet 12, a filter screen 54 is fixedly installed inside the fixed cover 53 on one side close to the feed box 51, a fan assembly 55 is fixedly installed inside the fixed cover 53, and a semiconductor refrigeration plate 56 is fixedly installed inside the side of the fixed cover 53 away from the filter screen 54.
[0037] Since one side of the dust suction vent 52 corresponds to the material guide chute 13, during the post-processing of the plastic products placed on the shelf 110, the waste generated when removing burrs will pass through the material guide chute 13, enter the interior of the feed box 51 from the dust suction vent 52, and be intercepted by the filter net 54 and fall into the interior of the waste box 57. The waste can be cleaned by pulling out the waste box 57.
[0038] Second embodiment
[0039] As attached Figure 1 - Attachment Figure 7 This is an embodiment of the present invention. On the basis of the first embodiment, a cutting device 6 is provided to perform a deburring treatment on the edges and corners of the cooled and formed plastic products. At the same time, during the cooling of the plastic products, the dust suction vent 52 will generate suction, and the waste generated during the deburring is sucked into the feed box 51 through the dust suction vent 52, and is intercepted by the filter 54 and falls into the waste box 57. A pressing device 4 is provided to press the plastic products on the placement rack 110 to prevent the plastic products from moving when the burrs are removed. At the same time, the direction of the plastic products is adjusted so that the cutting device 6 deburrs the other edges and corners of the plastic products, thereby realizing post-processing of the plastic products.
[0040] The second embodiment is further optimized relative to the first embodiment in that the pressing device 4 includes a fixing frame 41, the fixing frame 41 is fixedly installed on one side of the fixed box body 11, second lifting hydraulic cylinders 42 are fixedly installed on both sides of the top of the fixing frame 41, the bottom of the second lifting hydraulic cylinder 42 is fixedly connected with a support plate 43, a rotating motor 44 is fixedly installed on the top of the support plate 43, a limiting plate 45 is fixedly installed on the bottom of the rotating motor 44, a pressing plate 46 is fixedly installed on the bottom of the limiting plate 45, the size of the pressing plate 46 corresponds to the placement frame 110, and the pressing plate 46 is movably installed on the top of the placement frame 110.
[0041] Since the size of the pressing plate 46 corresponds to that of the placing rack 110, and the placing rack 110 is the same size as the plastic product, the plastic product is placed on the top of the placing rack 110 by the robotic arm. When the pressing plate 46 descends and presses on the top of the placing rack 110, the position of the plastic product outside the placing rack 110 and the pressing plate 46 is redundant burrs. At the same time, the rotating motor 44 controls the rotation of the pressing plate 46. Due to the friction between the pressing plate 46 and the placing rack 110 and the plastic product, the placing rack 110 and the plastic product will rotate synchronously with the pressing plate 46, thereby adjusting the position for removing burrs from the plastic product.
[0042] The positioning plate 677 is positioned by the limit plate 45. When the mobile hydraulic cylinder 62 controls the cutting frame 64 to move to one side of the pressing plate 46 and the placing frame 110, the positioning plate 677 will preferentially contact the side of the limit plate 45. At this time, the positions of the pressing plate 46 and the placing frame 110 are located on the side of the cutting blade 674. When the cutting blade 674 moves, it will cut the plastic products between the pressing plate 46 and the placing frame 110 to remove burrs.
[0043] Among them, the cutting device 6 includes two fixed rails 61, and the two fixed rails 61 are respectively fixedly installed on both sides of the top of the fixed box 11, and a mobile hydraulic cylinder 62 is fixedly installed on one side of the two fixed rails 61, and a sliding base 63 is fixedly installed on one side of the mobile hydraulic cylinder 62. The sliding base 63 is slidably installed on the top of the fixed rail 61, and a cutting frame 64 is fixedly installed on the top of the sliding base 63. A cutting motor 65 is fixedly installed on one side of the cutting frame 64, and a moving screw 66 is provided on one side of the cutting motor 65. The moving screw 66 is rotatably installed inside the cutting frame 64, and a cutting assembly 67 is threadedly installed on the outer surface of the moving screw 66, and the cutting assembly 67 is slidably installed inside the cutting frame 64.
[0044] Among them, the cutting assembly 67 includes a moving block 671, a bottom frame 672 is fixedly installed at the bottom of the moving block 671, positioning rods 673 are fixedly installed on both sides inside the bottom frame 672, a cutting blade 674 is movably sleeved on the outer surface of the positioning rod 673, a heating metal sheet 675 is fixedly installed on one side of the cutting blade 674, one side of the bottom frame 672 is fixedly installed on the positioning plate 677, and a buffer spring 676 is movably sleeved on the outer surface of the positioning rod 673.
[0045] The moving block 671 is threadedly mounted on the outer surface of the moving screw 66 , and the moving block 671 is slidably mounted inside the cutting frame 64 , and the bottom frame 672 is slidably mounted on one side of the top of the pressing plate 46 .

[0047] The buffer spring 676 is used to prevent the cutting blade 674 from colliding with the pressing plate 46 and the placement rack 110 during movement, thereby affecting the service life of the cutting blade 674. At the same time, when the cutting blade 674 cuts the plastic product to remove burrs, the heated metal sheet 675 grinds the cutting position of the plastic product to improve the deburring effect of the plastic product.
[0048] Third embodiment
[0049] As attached Figure 1 - Attachment Figure 8 As an embodiment of the present invention, plastic products are transmitted to the top of the lifting arm 37 through the conveyor belt 2 and are sensed by the pressure sensor on the top of the lifting arm 37. When each plastic product is added to the lifting arm 37, the weight of the plastic product on its top is sensed by the lifting arm 37, and the adjusting motor 32 controls the lifting screw 34 to rotate, so that the lifting arm 37 gradually descends, thereby causing the plastic products to descend. When the lifting arm 37 descends to the bottom of the limit slot 39, the adjusting motor 32 controls the lifting arm 37 to descend to the bottom of the support box 31, completing the stacking of the plastic products and preventing the plastic products from falling and being damaged.
[0050] The third embodiment is further optimized relative to the second embodiment in that the stacking device 3 includes a support box 31, a feed port 33 is provided at the upper end of one side of the support box 31, the support box 31 is arranged on the side of the conveyor belt 2 away from the working body 1, one end of the conveyor belt 2 is located at the bottom of the feed port 33, cavities are provided on both sides of the interior of the support box 31, and adjusting motors 32 are fixedly installed inside the cavities on both sides, a lifting screw 34 is provided at the bottom of the adjusting motor 32, the lifting screw 34 is rotatably installed inside the support box 31, and limiting rods 35 are fixedly installed at both ends of the interior of the support box 31, a lifting plate 36 is movably sleeved on the outer surface of the limiting rod 35, a lifting arm 37 is fixedly installed on the bottom of the lifting plate 36, and the lifting plate 36 is movably sleeved on the outer surface of the limiting rod 35.
[0051] The lifting arm 37 is located on one side of the conveyor belt 2. The plastic products are transferred to the top of the lifting arm 37. The pressure sensor on the top of the lifting arm 37 senses and the regulating motor 32 controls the gradual descent of the lifting arm 37, so that the plastic products on the top of the lifting arm 37 are flush with the conveyor belt 2, so that the second plastic product stays on the top of the first plastic product. In the above manner, the lifting arm 37 continues to descend, thereby completing the palletizing.
[0052] Among them, a stacking pallet 38 is movably sleeved on one side of the bottom end of the support box 31, a fixed handle 310 is fixedly installed on the upper end of one side of the stacking pallet 38, and limiting grooves 39 are provided on both sides of the bottom of the stacking pallet 38, and the lifting arm 37 is movably sleeved inside the limiting groove 39.
[0053] Among them, the stacking pallet 38 is located below one end of the conveyor belt 2, the lifting arm 37 is located at one end of the conveyor belt 2, grooves corresponding to the limit grooves 39 are opened on both sides of the bottom of the support box 31, the lifting arm 37 is embedded in the inside of the groove, and a pressure sensor is arranged on the top of the lifting arm 37.
[0054] Working principle of the present invention: When working, the first lifting hydraulic cylinder 17 extends, pushing the lifting box 18 to rise, and the lifting box 18 rises to the upper end of the fixed box 11, and the placement frame 110 is located on the top of the fixed box 11. At the same time, one side of the lifting box 18 corresponds to the air inlet 12 and is located on one side of the semiconductor cooling plate 56;
[0055] The plastic products are placed on the top of the placement rack 110 through the robot arm, and the fan assembly 55 starts to work, so that air enters the inside of the feed box 51 from the dust suction vent 52, and the air is heat-exchanged through the semiconductor cooling sheet 56 to generate cold air, which is discharged from the air outlet slot 111 through the connecting slot 19 to cool the plastic products on the placement rack 110. The plastic products are fully cooled before palletizing;
[0056] Then, the second lifting hydraulic cylinder 42 extends, controls the pressing plate 46 to descend and press on the plastic product on the top of the placing shelf 110, and the position of the plastic product outside the placing shelf 110 and the pressing plate 46 is redundant burrs;
[0057] The mobile hydraulic cylinder 62 pulls the sliding base 63 to move the cutting frame 64 to one side of the pressing plate 46 and the placing frame plate 110. The positioning plate 677 will first contact the side of the limiting plate 45. At this time, the corner of the plastic product between the pressing plate 46 and the placing frame plate 110 is located on the side of the cutting blade 674. The cutting motor 65 controls the moving screw 66 to rotate, and the cutting assembly 67 moves from one side of the corner of the plastic product to the other side. The cutting blade 674 cuts the burrs of the plastic product. At the same time, the heating metal sheet 675 heats and grinds the cutting position of the plastic product. After the cutting is completed, the mobile hydraulic cylinder 62 extends to push the cutting frame 64 away from the plastic product.
[0058] The rotating motor 44 controls the pressing plate 46 to rotate. Due to the friction between the pressing plate 46 and the placing frame 110 and the plastic product, the placing frame 110 and the pressing plate 46 rotate synchronously, so that the other side of the plastic product moves to one side of the cutting device 6, and the hydraulic cylinder 62 is moved to make the cutting frame 64 close to the plastic product again, and the above steps are repeated to cut the other side of the plastic product again.
[0059] After the cutting of the plastic products is completed, the first lifting hydraulic cylinder 17 contracts, causing the lifting box 18 to descend, and driving the plastic products to descend to the side of the push plate 16. The pushing cylinder 15 is started to push the plastic products to the top of the conveyor belt 2. The plastic products are transmitted to the top of the lifting arm 37 through the conveyor belt 2 and are sensed by the pressure sensor on the top of the lifting arm 37. When each plastic product is added to the lifting arm 37, the weight of the plastic product on its top is sensed by the lifting arm 37, and the adjusting motor 32 controls the lifting screw 34 to rotate, causing the lifting arm 37 to gradually descend, thereby causing the plastic products to descend. When the lifting arm 37 descends to the bottom of the limit groove 39, the adjusting motor 32 controls the lifting arm 37 to descend to the bottom of the support box 31, completing the stacking of the plastic products, and removing the plastic products inside the stacking tray 38 by pulling the fixed handle 310.
