[0035] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0036] like Figure 1-8 As shown, a drying device for electroplating plastic workpieces includes a drying chamber 201, a support frame 300, and a receiving cart 101. The drying chamber 201 is mounted on the support frame 300, and the receiving cart 101 is located on one side of the support frame 300. The drying chamber 201 is positioned above the receiving cart, which is used to receive plastic products delivered from the drying chamber 201. The drying chamber 201 is equipped with two conveyor rollers 203, a conveyor belt 204, and hot air nozzles 205. There are two conveyor rollers 203, and the conveyor belt 204 is wound around the two conveyor rollers 203. There are multiple hot air nozzles 205, which are evenly distributed on the inner wall of the drying chamber 201. The hot air nozzles 205 are connected to an external hot air delivery pipe to provide hot air to the drying chamber 201. Door curtains 202, made of rubber, are installed at both ends of the drying chamber 201 to reduce heat loss from the drying chamber 201.
[0037] Furthermore, the receiving cart 101 is equipped with a collecting plate 102, which can move up and down within the receiving cart 101. The receiving cart 101 is used to collect the products after the glue impregnation is completed. By moving the collecting plate 102 up and down, the height difference of the falling products is reduced while ensuring the capacity of the receiving cart 101, thus protecting the products and preventing them from falling from a height and being damaged.
[0038] The bottom of the collecting plate 102 is provided with a first support spring 106, and the middle of the collecting plate 102 protrudes upward to form a protrusion 1021; the first support spring 106 provides support force for the collecting plate 102, so that the collecting plate 102 is in a raised state; the products falling on the collecting plate 102 are scattered around the collecting plate 102, so as to prevent newly falling products from hitting the products on the collecting plate 102, and to provide further protection for the products.
[0039] Furthermore, the receiving cart 101 has a plurality of first mounting blocks 105 on its side wall. Each first mounting block 105 has a first movable groove communicating with the receiving cart 101. A support block 113 is provided in the first movable groove. One end of the support block 113 has an arc head, which is located inside the receiving cart 101. The collecting plate 102 abuts against the arc head of the support block 113. The support block 113 has a slider 1131. The inner wall of the first movable groove has a sliding groove for the slider 1131 to move. The slider 1131 and the sliding groove cooperate to limit the maximum distance of movement of the support block 113, so as to prevent the support block 113 from moving out of the first movable groove.
[0040] The first movable groove is provided with a movable block 115, and a second support spring 114 is provided on the movable block 115. One end of the second support spring 114 abuts against the support block 113. A threaded rod 116 is rotatably connected to the movable block 115. A threaded hole corresponding to the threaded rod 116 is provided on the side wall of the first movable groove. The threaded rod 116 passes through the threaded hole and a wing nut 117 is sleeved on the threaded rod 116.
[0041] The position of the movable block 115 in the first movable groove can be adjusted by rotating the threaded rod 116, thereby changing the supporting force of the second support spring 114 on the support block 113, changing the load-bearing capacity of the collecting plate 102, and ensuring that the collecting plate 102 pushes the support block 113 to move and then descends after receiving a specified weight; by setting multiple support blocks 113, the collecting plate 102 moves down a specified distance after receiving a specified weight each time, ensuring the height difference of the product falling at the drying box 201, and providing a buffer for the product; the wing nut 117 is used to fix the threaded rod 116, thereby fixing the movable block 115 in a specified position, ensuring the supporting force of the support block 113 on the collecting plate 102.
[0042] Furthermore, the support block 113 is provided with a connecting rod 119, which extends out of the first movable groove. The connecting rod 119 is provided with a first push plate 120. The first push plate 120 is provided with a second movable groove, and a movable plate 121 is provided in the second movable groove. The movable plate 121 is provided with a second push plate 1211. The first push plates 120 on two adjacent first mounting blocks 105 are arranged vertically adjacent to each other. The top of the movable plate 121 on the topmost first push plate 120 extends out from the top of the second movable groove, which facilitates pushing the movable plate 121 to move. The side wall of the movable plate 121 is provided with a protrusion, and the inner wall of the second movable groove is provided with a guide groove. The protrusion is embedded in the guide groove so that the movable plate 121 can only move along the second movable groove and cannot be dislodged from the second movable groove.
[0043] After all the products in the receiving cart 101 are removed, the second push plate 1211 is pushed down. The second push plate 1211 drives the movable plate 121 to move down. The movable plate 121 on the upper first push plate 120 is inserted into the second movable slot of the lower first push plate 120, so that the two adjacent first push plates 120 are connected through the movable plate 121. The first push plate 120 is pulled away from the receiving cart 101. The first push plate 120 drives the support block 113 to move into the first movable slot. The first support spring 106 pushes the collecting plate 102 to move up and reset. The collecting plate 102 moves back to the top of the receiving cart 101.
[0044] Furthermore, the protrusion 1021 is provided with a through groove, and a guide plate 107 and a receiving plate 104 are provided in the through groove. There are two receiving plates 104 and two guide plates 107. The two receiving plates 104 are connected by a connecting roller 109. One end of the receiving plate 104 is slidably connected to the inner wall of the through groove, and the end of the receiving plate 104 slidably connected to the inner wall of the through groove can rotate. The guide plate 107 is inclined on one side of the receiving plate 104.
[0045] The receiving trolley 101 has a second mounting block 110 at its bottom, a support rod 111 on the connecting roller 109, a third movable groove on the second mounting block 110, the support rod 111 is inserted into the third movable groove, and a third support spring 112 is provided at the bottom of the support rod 111, with the bottom of the third support spring 112 abutting against the bottom of the third movable groove.
[0046] When the collecting plate 102 descends, it moves relative to the connecting roller 109. The connecting roller 109 bulges upward, causing the receiving plate 104 to rotate. The receiving plate 104 forms an inclined surface, causing all the products to roll onto the guide plate 107. The products then roll onto the collecting plate 102 around the collecting plate 102 via the guide plate 107, where they are collected. When the receiving cart receives the plastic products falling from the drying box 201, the cart moves so that the products falling from the drying box 201 land precisely on the protrusion 1021, preventing the products from colliding with the products on the receiving plate 104 as soon as they fall, thus providing good protection for the products.
[0047] The receiving cart 101 is equipped with casters 118 at the bottom and handles 103 on the side wall for easy movement.
[0048] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
