Description

Technical Field

[0001] This utility model belongs to the field of plastic production technology, specifically, it relates to a plastic extrusion cooling molding device. Background Technology

[0002] Wooden pallets are pallets made from natural wood and are the most widely used type of pallet. Pallets are horizontal platform devices used for assembling, stacking, handling, and transporting goods and products as unit loads. They are generally made of wood, metal, and fiberboard, facilitating the loading, unloading, and handling of unitized materials and small quantities of goods. Pallets are mainly made of wood, plastic, and metal, with wood being the most widely used due to its affordability and sturdiness. In plastic pipe production, the cooling process after extrusion is a crucial step in plastic pipe forming. Rapid cooling of the pipe ensures uniform shrinkage, guaranteeing the quality and aesthetics of the plastic pipe.

[0003] A search revealed that CN 210336791U discloses an extrusion molding cooling device for plastic pipe production. This invention adjusts the spray angle of the nozzle by adjusting the movement of the moving rack and the rotation of the rotating half gear, thereby adjusting the spray position of the nozzle. This allows for adjustment of the cooling spray position according to the actual production of the plastic pipe, resulting in better cooling effect for the plastic pipe.

[0004] This device can improve the cooling effect by adjusting the water spray angle. However, the plastic tube in the device does not have the ability to rotate during transportation. This means that the outer wall of the plastic tube at the bottom end will not be cooled by the cooling water, which greatly affects the cooling effect of the plastic tube.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To address the technical problem that while the device can improve cooling efficiency by adjusting the water spray angle, the plastic tube in this device does not rotate during transportation, resulting in the outer wall of the plastic tube at the bottom not receiving sufficient cooling water, thus significantly affecting the cooling effect, the basic concept of this utility model is as follows:

[0007] A plastic extrusion cooling molding apparatus includes a supporting water guide frame;

[0008] A support leg is fixedly connected to the bottom end of the supporting water guide frame. A rotating cooling mechanism is provided on the supporting water guide frame. A filtering and stirring mechanism is provided on one side of the rotating cooling mechanism. The rotating cooling mechanism includes a support plate fixedly connected to the outer wall of the supporting water guide frame.

[0009] A dual-axis motor is fixedly connected to one end of the support plate away from the outer wall of the support water guide frame. A conveyor belt is rotatably mounted on one output end of the dual-axis motor. A fixed frame is rotatably mounted on the outer wall of the conveyor belt. The bottom end of the fixed frame is fixedly connected to the top end of the support water guide frame. A fixed plate is fixedly connected to the conveyor belt. A support shaft is rotatably mounted on the outer wall of the fixed plate. A gear is fixedly connected to one end of the outer wall of the support shaft. A toothed block is fixedly connected to the top end of the fixed frame. The gear and the toothed block are meshed. A cooling box is fixedly installed on one outer wall of the support leg. A pump body is connected to the outer wall of the cooling box. A connecting pipe is connected to the output end of the pump body. A water collecting plate is connected to the end of the connecting pipe away from the pump body. One end of the water collecting plate is fixedly connected to the outer wall of the fixed frame. A water spray head is connected to the bottom end of the water collecting plate.

[0010] In a preferred embodiment of this utility model, the filtering and stirring mechanism includes a rotating rod. One end of the rotating rod is rotatably connected to the inner wall of the cooling box via a bearing. A transmission belt is rotatably mounted on the end of the rotating rod away from the bearing. The transmission belt is rotatably mounted on the outer output end of the dual-shaft motor at the end away from the rotating rod. A stirring blade is fixedly connected to the outer wall of the rotating rod. A retaining frame is engaged with the outer wall of the cooling box. A filter plate is fixedly connected to the bottom end of the retaining frame.

[0011] In a preferred embodiment of this utility model, the number of supporting rotating shafts is several, and the supporting rotating shafts are evenly and equidistantly distributed in pairs on the conveyor belt.

[0012] In a preferred embodiment of this utility model, the supporting water guide frame is configured with a left-high and right-low shape, and one end of the supporting water guide frame is connected to the opening of the top pipe of the cooling tank.

[0013] In a preferred embodiment of this utility model, the number of water spray heads is several, and the water spray heads are evenly and equidistantly distributed at the bottom end of the water collection plate.

[0014] In a preferred embodiment of this utility model, the bottom end of the card frame is provided with a card groove, the inner wall of which is appropriately matched with the thickness of the inner and outer walls of the cooling box, and there are two of them distributed on the left and right sides of the filter plate in a left-right symmetrical structure.

[0015] In a preferred embodiment of this utility model, the outer wall of the filter plate is properly fitted to the inner wall of the cooling box.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This invention involves starting a dual-axis motor, whose inner output end drives a conveyor belt to rotate. The rotation of the conveyor belt moves a fixed plate and a supporting shaft, which in turn moves the plastic tube at its top. During this movement, the supporting shaft drives a gear, which meshes with a gear block. This gear rotation then drives one side of the supporting shaft to rotate. The rotation of this supporting shaft creates friction with the plastic tube, thus engaging with the other side of the supporting shaft and causing the plastic tube to rotate. Simultaneously, the pump body starts, and its output end transmits cooling water from inside the cooling tank to a water-collecting plate through a connecting pipe. The water is then sprayed onto the moving plastic tube through spray nozzles. The rotation of the plastic tube ensures that the cooling water is evenly distributed throughout, preventing uneven cooling at the bottom of the plastic tube and thus ensuring the production quality of the plastic tube.

[0018] In this invention, the cooled water flows downwards into the supporting water guide frame, and then is transported to the cooling tank for further cooling. Before falling into the cooling tank, the water is filtered by a filter plate, which removes impurities left behind after cooling, preventing blockage of the pump and spray nozzles during subsequent circulation. Then, with the start of the dual-shaft motor, its outer output end drives the transmission belt to rotate, which in turn drives the rotating rod and stirring blades. The rotation of the stirring blades agitates the cooling water inside the cooling tank, resulting in more uniform cooling, faster cooling rate, and improved subsequent cooling efficiency.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figures 1 to 4 As shown, a plastic extrusion cooling molding device includes a supporting water guide frame 1, a supporting leg 2 fixedly connected to the bottom end of the supporting water guide frame 1, a rotating cooling mechanism 31 provided on the supporting water guide frame 1, a filtering and stirring mechanism 32 provided on one side of the rotating cooling mechanism 31, the rotating cooling mechanism 31 including a supporting plate 311 fixedly connected to the outer wall of the supporting water guide frame 1, a dual-axis motor 312 fixedly connected to one end of the supporting plate 311 away from the outer wall of the supporting water guide frame 1, a conveyor belt 314 rotatably provided on one output end of the dual-axis motor 312, a fixing frame 313 rotatably provided on the outer wall of the conveyor belt 314, the bottom end of the fixing frame 313 fixedly connected to the top end of the supporting water guide frame 1, and a fixed connection on the conveyor belt 314. There is a fixed plate 315, and a support shaft 316 is rotatably mounted on the outer wall of the fixed plate 315. A gear 317 is fixedly connected to the outer wall of one end of the support shaft 316. A toothed block 318 is fixedly connected to the top of the fixed frame 313. The gear 317 and the toothed block 318 are meshed. A cooling box 319 is fixedly installed on the outer wall of one side of the support leg 2. A pump body 3110 is connected to the outer wall of the cooling box 319. A connecting pipe 3111 is connected to the output end of the pump body 3110. A water collecting plate 3112 is connected to the end of the connecting pipe 3111 away from the pump body 3110. One end of the water collecting plate 3112 is fixedly connected to the outer wall of the fixed frame 313. A water spray head 3113 is connected to the bottom end of the water collecting plate 3112.

[0028] Furthermore, there are several supporting shafts 316, which are evenly and equidistantly distributed in pairs on the conveyor belt 314, so that the plastic tube can be supported and rotated by the pairs of supporting shafts 316.

[0029] Furthermore, the supporting water guide frame 1 is designed with the left side higher than the right side. One end of the supporting water guide frame 1 is connected to the opening of the top pipe of the cooling tank 319. In this way, the cooled water will flow into the cooling tank 319 by gravity for subsequent recycling.

[0030] Furthermore, there are several spray heads 3113, which are evenly and equidistantly distributed at the bottom of the water collection plate 3112, so as to fully spray and cool the plastic pipe, thereby improving the cooling effect.

[0031] The filtering and stirring mechanism 32 includes a rotating rod 321. One end of the rotating rod 321 is rotatably connected to the inner wall of the cooling box 319 via a bearing. A transmission belt 322 is rotatably mounted on the end of the rotating rod 321 away from the bearing. The end of the transmission belt 322 away from the rotating rod 321 is rotatably mounted on the outer output end of the dual-shaft motor 312. A stirring blade 323 is fixedly connected to the outer wall of the rotating rod 321. A retaining frame 324 is engaged on the outer wall of the cooling box 319. A filter plate 325 is fixedly connected to the bottom end of the retaining frame 324.

[0032] Furthermore, the bottom of the card frame 324 is provided with a card slot. The inner wall of the card slot is appropriately matched with the thickness of the inner and outer walls of the cooling box 319. There are two slots in a left-right symmetrical structure distributed on the left and right sides of the filter plate 325. This ensures the stability of the card frame 324 after it is engaged with the cooling box 319, thereby ensuring the installation stability of the filter plate 325.

[0033] Furthermore, the outer wall of the filter plate 325 is properly fitted to the inner wall of the cooling box 319, thereby ensuring that the filter plate 325 can completely filter the cooling water and prevent gaps from forming between it and the inner wall of the cooling box 319.

[0034] The implementation principle of the plastic extrusion cooling molding device in this embodiment is as follows: After extrusion, the plastic tube is placed on two adjacent support shafts 316. Then, the dual-shaft motor 312 is started, and its inner output end drives the conveyor belt 314 to rotate. The rotation of the conveyor belt 314 drives the fixed plate 315 and the support shaft 316 to move. The movement of the support shaft 316 drives the plastic tube at its top to move. During the movement of the support shaft 316, the gear 317 will move. At this time, the gear 317 will mesh with the tooth block 318 and rotate. The rotation of the gear 317 drives one of the support shafts on one side. The shaft 316 rotates, and the rotation of the supporting shaft 316 generates friction with the plastic tube, thus forming a cooperation with the supporting shaft 316 on the other side, which drives the plastic tube to rotate. In this way, the plastic tube rotates during movement, and the pump body 3110 is started simultaneously. Its output end will transfer the cooling water inside the cooling box 319 to the water collection plate 3112 through the connecting pipe 3111, and then spray it onto the moving plastic tube through the spray head 3113. The rotation of the plastic tube allows the cooling water to be evenly and comprehensively sprayed onto it, thereby preventing the bottom of the plastic tube from being cooled by the cooling water, which would cause uneven heating and thus affect the production quality of the plastic tube.

[0035] After cooling, the cooling water flows downwards into the supporting water guide frame 1, and then is transmitted to the cooling tank 319 for cooling. Before falling into the cooling tank 319, it is filtered by the filter plate 325, which filters out impurities left behind after cooling, preventing blockage of the pump body 3110 and the spray head 3113 during subsequent circulation. Then, with the start of the dual-shaft motor 312, its outer output end will drive the transmission belt 322 to rotate. The transmission belt 322 will drive the rotating rod 321 and the stirring blade 323 to rotate. The rotation of the stirring blade 323 will stir and flow the cooling water inside the cooling tank 319, making the cooling water cool more evenly, accelerating the cooling rate, and improving the subsequent cooling efficiency.
