Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing technology, and in particular to a cooling device for plastic products. Background Technology

[0002] Plastic products are made of plastic, a high molecular weight compound polymerized through addition or condensation polymerization, commonly known as plastic or resin. Their composition and shape can be freely changed. They consist of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Cooling is required during the production of plastic products; however, conventional cooling devices cannot effectively cool the bottom of the plastic products.

[0003] Existing patent CN222309518U describes a cooling rack for plastic product manufacturing. The plastic products are placed on a breathable mesh. When a fan is activated, outside air enters a first air supply pipe under the fan's influence. The air in the first air supply pipe then enters a second air supply pipe, and the air in the second air supply pipe is blown out through an air blowing hood. The blown air cools the plastic products on the breathable mesh. This method effectively improves the overall cooling performance of the plastic products.

[0004] However, when using a cooling rack for plastic product manufacturing based on an existing patent, if the bottom area of ​​the plastic product is larger than the circular area of ​​the breathable mesh, the air blown out through the air blower can only cool the bottom of the plastic product, while other parts of the plastic product cannot be cooled, thus reducing the cooling efficiency of the plastic product. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for plastic products, which solves the problem that when the bottom area of ​​the plastic product is larger than the circular area of ​​the breathable mesh, the air blown out by the air blower can only cool the bottom of the plastic product, while other parts of the plastic product cannot be cooled, thus reducing the cooling efficiency of the plastic product.

[0006] To achieve the above objectives, this utility model provides a cooling device for plastic products, including a cooling rack and a placement plate. The placement plate is fixedly installed on the cooling rack and has ventilation slots. It also includes an air-cooling device, which comprises a Z-shaped tube, an arc-shaped plate, a drive rod, an air-cooling cylinder, a support assembly, and a transmission assembly. The cooling rack has a circular groove on one side near the placement plate. The air-cooling cylinder is installed on the cooling rack via the support assembly, and a fan is provided at one end of the air-cooling cylinder. The Z-shaped tube is rotatably installed on the air-cooling cylinder and passes through the circular groove. Air holes are provided on the Z-shaped tube. The arc-shaped plate is rotatably installed on the cooling rack via the transmission assembly. The drive rod is fixedly installed on the arc-shaped plate and contacts the Z-shaped tube.

[0007] The transmission assembly includes a transmission gear ring, a first support rod, a second support rod, and a rotating component. The transmission gear ring has a first annular groove and a second annular groove on both sides. The first support rod is fixedly installed on the cooling rack. The second support rod is fixedly installed on the placement plate. The first support rod and the second support rod are located in the first annular groove and the second annular groove, respectively. The rotating component is disposed on the cooling rack.

[0008] The rotating component includes a rotating shaft and a rotating gear. The rotating shaft is rotatably mounted on the cooling rack. The rotating gear is fixedly mounted on the rotating shaft and meshes with the transmission gear ring.

[0009] The support assembly includes a fixing ring and a support frame. The fixing ring is fixedly installed on the air-cooled cylinder, and the support frame is fixedly installed on the cooling frame and fixedly connected to the fixing ring.

[0010] The air-cooling device further includes an air-collecting assembly, which includes a mounting rod and an air-collecting shroud. The mounting rod is fixedly installed inside the air-cooling cylinder, and the air-collecting shroud is fixedly installed on the mounting rod.

[0011] This utility model discloses a cooling device for plastic products. In use, plastic products are placed sequentially on a placement plate. Then, the fan is started, and the fan blows external airflow through the air collector hood into the Z-shaped tube. The airflow then blows onto the plastic products on the placement plate through the air holes, cooling the plastic products. Simultaneously, a motor controls the rotation of a rotating shaft, which drives a rotating gear to rotate. The rotating gear meshes with a transmission gear ring, causing the transmission gear ring to rotate on the first and second support rods. The rotation of the transmission gear ring, in turn, drives a driving rod to rotate circumferentially around the transmission gear ring via an arc-shaped plate. The driving rod, in turn, drives the left end of the Z-shaped tube to rotate circumferentially around the placement plate. This allows the Z-shaped tube to blow air onto all four sides of the plastic products, effectively cooling all sides of the plastic products and improving the cooling efficiency.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] The embodiment of this application is as follows:

[0020] Please see Figure 1-4 , Figure 1 This is a schematic diagram of the overall structure of a plastic product cooling device according to this utility model. Figure 2 This is a structural schematic diagram of the air-cooling device of this utility model. Figure 3 This is a schematic diagram showing the connection between the first support rod and the transmission gear ring of this utility model. Figure 4 This is a schematic diagram showing the connection between the Z-shaped tube and the air-cooled cylinder of this utility model.

[0021] This utility model provides a cooling device for plastic products: it includes a cooling rack 101 and a placement plate 102, and also includes an air-cooling device. The air-cooling device includes a Z-shaped tube 104, an arc-shaped plate 105, a driving rod 106, an air-cooling cylinder 107, a support assembly, and a transmission assembly. The transmission assembly includes a transmission gear ring 111, a first support rod 112, a second support rod 113, and a rotating component. The rotating component includes a rotating shaft 116 and a rotating gear 117. The support assembly includes a fixing ring 118 and a support frame 119. The air-cooling device also includes an air-collecting assembly, which includes a mounting rod 120 and an air-collecting hood 121. When cooling plastic products with the aforementioned device, if the bottom area of ​​the plastic product is larger than the circular area of ​​the breathable mesh, the air blown out through the air-blowing hood can only cool the bottom of the plastic product, while other parts of the plastic product cannot be cooled, thus reducing the cooling efficiency of the plastic product. The aforementioned solution can be used in the scenario of cooling plastic products after molding.

[0022] In this embodiment, the transmission assembly drives the arc plate 105 and the driving rod 106 to rotate circumferentially, and further causes the left end of the Z-shaped tube 104 to rotate circumferentially, thereby enabling the Z-shaped tube 104 to effectively blow air to cool the plastic product from all sides.

[0023] The cooling rack 101 has a circular groove 108 on one side near the placement plate 102. The air-cooled cylinder 107 is mounted on the cooling rack 101 via the support assembly. A fan 109 is provided at one end of the air-cooled cylinder 107. A Z-shaped tube 104 is rotatably mounted on the air-cooled cylinder 107 and passes through the circular groove 108. The Z-shaped tube 104 has air holes 110. An arc-shaped plate 105 is rotatably mounted on the cooling rack 101 via the transmission assembly. A driving rod 106 is fixedly mounted on the arc-shaped plate 105 and contacts the Z-shaped tube 104. The Z-shaped tube 104 has a Z-shaped structure, and its left end is closed. The left end of the air-cooled cylinder 107 is also closed. 04 The bearing rotates with the air-cooling cylinder 107. The arc-shaped plate 105 has an arc-shaped structure. The driving rod 106 is set on both sides of the arc-shaped plate 105. The ventilation groove 103 on the placement plate 102 facilitates the Z-shaped tube 104 to blow air onto the bottom of the plastic product. In use, driven by the fan 109, the external airflow passes through the air-cooling cylinder 107 and the Z-shaped tube 104, and is finally blown onto the plastic product on the placement plate 102 through the air hole 110. At the same time, the transmission assembly drives the arc-shaped plate 105 and the driving rod 106 to rotate circumferentially, and further causes the left end of the Z-shaped tube 104 to rotate circumferentially, so that the Z-shaped tube 104 can effectively blow air and cool the plastic product from all sides.

[0024] Secondly, the transmission gear ring 111 has a first annular groove 114 and a second annular groove 115 on both sides respectively; the first support rod 112 is fixedly installed on the cooling rack 101; the second support rod 113 is fixedly installed on the placement plate 102, and the first support rod 112 and the second support rod 113 are respectively located in the first annular groove 114 and the second annular groove 115; the rotating component is arranged on the cooling rack 101, the inner side of the transmission gear ring 111 is provided with meshing teeth, the first support rod 112 and the second support rod 113 are respectively arranged on the left and right sides of the transmission gear ring 111, the second support rod 113 has an L-shaped structure, and the axis of the transmission gear ring 111 also coincides with the right end axis of the Z-shaped tube 104. Through the arrangement of the first support rod 112 and the second support rod 113, the transmission gear ring 111 can be supported. The rotating component drives the transmission gear ring 111 to rotate, thereby causing the transmission gear ring 111 to drive the arc plate 105 to rotate circumferentially.

[0025] Furthermore, the rotating shaft 116 is rotatably mounted on the cooling rack 101; the rotating gear 117 is fixedly mounted on the rotating shaft 116 and meshes with the transmission gear ring 111. The rotating shaft 116 is driven by a motor, and the rotating gear 117 is located inside the transmission gear ring 111. The motor drives the rotating shaft 116 to rotate, and the rotating shaft 116 drives the rotating gear 117 to rotate. The rotating gear 117, through meshing with the transmission gear ring 111, drives the transmission gear ring 111 to rotate.

[0026] Furthermore, the fixing ring 118 is fixedly installed on the air-cooled cylinder 107; the support frame 119 is fixedly installed on the cooling frame 101 and is fixedly connected to the fixing ring 118. The fixing ring 118 is welded to the outside of the air-cooled cylinder 107. The support frame 119 has an L-shaped structure. Through the cooperation of the fixing ring 118 and the support frame 119, the air-cooled pipe is supported.

[0027] Finally, the mounting rod 120 is fixedly installed inside the air-cooled cylinder 107; the air collector shroud 121 is fixedly installed on the mounting rod 120. There are three sets of mounting rods 120, which are arranged in a ring inside the air-cooled cylinder 107. The air collector shroud 121 is welded to the mounting rod 120. The air collector shroud 121 has a conical structure. By setting the air collector shroud 121, the airflow blown in by the fan 109 is concentrated, thereby increasing the air pressure.

[0028] In this embodiment, during use, plastic products are placed sequentially on the placement plate 102. Then, the fan 109 is activated, blowing external airflow through the air collector shroud 121 into the Z-shaped tube 104. The airflow then passes through the air vents 110 onto the plastic products on the placement plate 102, cooling them. Simultaneously, a motor controls the rotation of the rotating shaft 116, which drives the rotating gear 117 to rotate. The rotating gear 117 meshes with the transmission gear ring. The transmission gear ring rotates on the first support rod 112 and the second support rod 113. The rotation of the transmission gear ring, in turn, drives the driving rod 106 to rotate circumferentially around the transmission gear ring via the arc plate 105. The driving rod 106 then drives the left end of the Z-shaped tube 104 to rotate circumferentially around the placement plate 102, so that the Z-shaped tube 104 blows air to all four sides of the plastic product, thereby effectively cooling all four sides of the plastic product and improving the cooling efficiency of the plastic product.
