Description

Technical Field

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

[0002] In the plastics processing industry, the cooling process is crucial to product quality and production efficiency. Currently, most plastics cooling devices use traditional water cooling methods, cooling the products through heat-conducting plates and circulating cooling water. However, these devices generally have significant drawbacks: firstly, after prolonged use, scale buildup in the cooling water tanks inside the heat-conducting plates easily accumulates, severely affecting heat transfer efficiency, leading to decreased cooling effect and increased energy consumption; secondly, existing cooling devices lack effective water flow disturbance design, with the cooling water flowing in a laminar state within the tanks, resulting in poor convective heat transfer between the cooling water and the heat-conducting plates. This leads to long cooling times and low efficiency for plastics, making it difficult to meet the ever-increasing production demands. Furthermore, in traditional device structures, cleaning scale usually requires manual disassembly, which is cumbersome, time-consuming, and labor-intensive, significantly impacting the continuity and stability of production.

[0003] While existing technologies can achieve a certain cooling effect during use, they suffer from drawbacks: the lack of an automatic scale removal structure and an effective turbulence-based heat exchange enhancement structure. In view of this, we propose a processing cooling device for plastic products that solves the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background art by proposing a processing cooling device for plastic products.

[0005] The technical solution of this utility model is as follows: A processing cooling device for plastic products includes a mounting frame, an upper heat-conducting plate, and a lower heat-conducting plate. A linear motor is fixedly connected to the upper outer wall of the mounting frame, and the output shaft of the linear motor is fixedly connected to the upper outer wall of the upper heat-conducting plate. A lower heat-conducting plate is provided below the upper heat-conducting plate. Water tanks are provided in both the upper and lower heat-conducting plates. A lead screw is provided in the water tank, and a movable plate is provided on the lead screw. The movable plate is connected to the lead screw through a threaded seat.

[0006] When using the processing and cooling device for plastic products in this solution, the plastic product to be cooled is first placed on a carrier plate. The carrier plate can move flexibly via guide rails, facilitating the placement and removal of the product. Then, the linear motor is started, and its output shaft drives the upper heat-conducting plate downwards, bringing it into contact with the upper surface of the plastic product. Next, cooling water is injected into the water tanks inside the upper and lower heat-conducting plates through the water inlet. The cooling water flows within the water tanks, utilizing the thermal conductivity of the upper and lower heat-conducting plates to efficiently cool the plastic product. Simultaneously, the rotary motor is started, and its output shaft drives the lead screw to rotate. The lead screw drives the moving plate to move along the lead screw axis within the water tank via a threaded seat. The first and second scrapers, arranged in a staggered pattern below the moving plate, move with the moving plate, scraping the inner wall of the water tank to effectively remove scale and impurities, preventing scale from affecting the heat conduction efficiency and ensuring the stability of the cooling effect. After cooling is complete, the cooling water in the water tank is drained through the drain outlet. The linear motor is then started again, and the upper heat-conducting plate moves upwards, allowing the cooled plastic product to be removed.

[0007] Preferably, a plurality of first and second scrapers arranged in a linear array are provided below the movable plate, and the first and second scrapers are arranged in an alternating pattern.

[0008] Preferably, the rotation center of the lead screw is fixedly connected to the output shaft of the rotary motor, and a rotary motor is provided on one side of the outer wall of both the upper and lower heat-conducting plates.

[0009] Preferably, both the upper and lower heat-conducting plates have water inlets on one side and drain outlets on the other side.

[0010] Preferably, the lower heat-conducting plate is provided with a guide rail, a carrying plate is provided inside the guide rail, and a heat-conducting sheet is fixedly connected to the lower outer wall of the carrying plate.

[0011] Preferably, the upper outer wall of the movable plate is fixedly connected with a mating groove, and the upper inner wall of the water tank is fixedly connected with a limiting strip, with the mating groove located on the limiting strip.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] I. This utility model achieves efficient removal of scale from heat transfer surfaces through a movable plate and staggered first and second scrapers arranged within a water tank. During the operation of the cooling device, a rotating motor drives a lead screw to rotate, causing the movable plate to reciprocate linearly along the lead screw axis. The two sets of scrapers then thoroughly scrape the inner wall of the water tank. This effectively avoids the problem of reduced heat conduction efficiency due to scale buildup, ensuring that the upper and lower heat conduction plates can continuously and stably transfer heat from the plastic product to the cooling water, maintaining the efficient operation of the cooling device, extending its service life, and reducing maintenance costs and downtime caused by scale problems.

[0014] Second, based on the first beneficial effect, the scraper, during its reciprocating motion to remove scale, also periodically disturbs the water flow in the tank. This disturbance breaks the original laminar flow, creating turbulent flow. The convective heat transfer between the cooling water and the heat-conducting plate is significantly enhanced in this turbulent state, allowing the heat absorbed by the heat-conducting plate from the plastic product to be carried away more quickly. Compared to the relatively stable water flow in traditional cooling devices, this invention significantly improves heat exchange efficiency through the scraper's turbulent flow, thereby shortening the cooling time of plastic products, increasing production efficiency, and ensuring more uniform cooling of the plastic products, effectively improving product quality.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Please see Figures 1-6 As shown, this embodiment is a processing and cooling device for plastic products, including a mounting frame 3, an upper heat-conducting plate 1, and a lower heat-conducting plate 5. The device is characterized by: a linear motor 2 fixedly connected to the upper outer wall of the mounting frame 3; the output shaft of the linear motor 2 fixedly connected to the upper outer wall of the upper heat-conducting plate 1; a lower heat-conducting plate 5 located below the upper heat-conducting plate 1; a water tank 17 located within both the upper and lower heat-conducting plates 1 and 5; a lead screw 8 located within the water tank 17; and a movable plate 16 located within the lead screw 8. The movable plate 16 is connected to the lead screw 8 via a threaded seat 9. During use, the linear motor 2 is driven, and its output shaft causes the upper heat-conducting plate 1 to move downwards along a vertical direction, bringing the upper heat-conducting plate 1 into contact with the plastic product placed on the carrier plate 12 of the lower heat-conducting plate 5.

[0030] Example 2

[0031] Please see Figures 1-6 As shown, this embodiment further includes, based on embodiment 1, a plurality of first scrapers 14 and second scrapers 15 arranged in a linear array below the movable plate 16. The first scrapers 14 and second scrapers 15 are arranged in an alternating manner. In use, the two sets of scrapers can completely remove the scale from the heat transfer surface, and the alternating arrangement can provide a discharge path for the scraped scale. At the same time, the movement of the scrapers can disturb the water flow.

[0032] The rotation center of the lead screw 8 is fixedly connected to the output shaft of the rotary motor 4. The upper heat-conducting plate 1 and the lower heat-conducting plate 5 are both equipped with a rotary motor 4 on one side of their outer wall. In use, driving the rotary motor 4 can make the lead screw 8 rotate. The rotation of the lead screw 8 can drive the moving plate 16 to move, thereby moving the two sets of scrapers.

[0033] Both the upper heat-conducting plate 1 and the lower heat-conducting plate 5 have water inlets 6 on one side and drain outlets 7 on the other side. In use, the water inlets 6 of the upper heat-conducting plate 1 and the lower heat-conducting plate 5 are connected to the outlet of the circulating water cooling box through pipes, and the drain outlets 7 are connected to the water inlets 6 of the circulating water cooling box through pipes, forming a complete cooling water circulation system.

[0034] The lower heat-conducting plate 5 is equipped with a guide rail, and a carrying plate 12 is installed inside the guide rail. A heat-conducting sheet 13 is fixedly connected to the lower outer wall of the carrying plate 12. During use, the carrying plate 12 can move along the guide rail track without detaching from the guide rail. The mobility of the carrying plate 12 provides sufficient operating space for loading and unloading materials. The heat-conducting sheet 13 has good heat exchange efficiency. During the cooling process, the heat emitted by the plastic product will be quickly transferred to the carrying platform. The heat-conducting sheet 13 at the bottom of the carrying platform can absorb the heat and quickly conduct it to the lower heat-conducting plate 5 due to its excellent thermal conductivity.

[0035] The upper outer wall of the movable plate 16 is fixedly connected with a mating groove 10, and the upper inner wall of the water tank 17 is fixedly connected with a limiting strip 11. The mating groove 10 is provided on the limiting strip 11. In use, the mating groove 10 can prevent the movable plate 16 from deflecting when it moves, so that the movable plate 16 only makes linear movement along the axis of the lead screw 8.

[0036] Instructions for use: When using this device, first place the plastic product to be cooled on the carrier plate 12. The carrier plate 12 can move flexibly via guide rails, facilitating the placement and removal of the product. Then, start the linear motor 2, whose output shaft drives the upper heat-conducting plate 1 downward, so that the upper heat-conducting plate 1 contacts the upper surface of the plastic product. Next, coolant is injected into the water tank 17 inside the upper heat-conducting plate 1 and the lower heat-conducting plate 5 through the water inlet 6. The coolant flows in the water tank 17, utilizing the thermal conductivity of the upper heat-conducting plate 1 and the lower heat-conducting plate 5 to efficiently cool the plastic product. Simultaneously, start the rotary motor 4. Its output shaft drives the lead screw 8 to rotate, and the lead screw 8 drives the moving plate 16 to move along the axis of the lead screw 8 in the water tank 17 through the threaded seat 9; the first scraper 14 and the second scraper 15 arranged alternately below the moving plate 16 will move with the moving plate 16 to scrape the inner wall of the water tank 17, effectively removing the scale and impurities attached to the water tank 17, avoiding the scale from affecting the heat conduction efficiency, and ensuring the stability of the cooling effect. After cooling is completed, the cooling water in the water tank 17 is discharged through the drain 7. The linear motor 2 is started again, the upper heat conduction plate 1 moves up, and the cooled plastic product can be taken out.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
