Description

Technical Field

[0001] This utility model relates to the field of plastic particle heating and compression technology, and in particular to a plastic particle heating and compression device that can be rapidly cooled. Background Technology

[0002] Plastic particles are the raw material form of plastics, usually in granular form. They are made by mixing polymer compounds with various additives through a certain process. These particles are easier to handle and transport during the manufacturing process and are the "secret weapon" for manufacturing various plastic products. In the production process of plastic products, plastic particles need to go through a series of processes such as heating, compression, and cooling to be formed into the final product.

[0003] In traditional rapid-cooling plastic particle heating and compression devices, activated carbon filters can effectively adsorb and remove harmful substances in flue gas. However, since existing activated carbon filters are mostly installed in a fixed manner, their purification efficiency will decrease after long-term use, thus reducing the service life of the flue gas purification device. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing plastic particle heating and compression device with rapid cooling has the disadvantage that it is inconvenient to maintain and replace the activated carbon filter screen during use. Therefore, we propose a plastic particle heating and compression device with rapid cooling.

[0005] To achieve the above objectives, this application adopts the following technical solution: a rapidly cooling plastic particle heating and compression device, comprising a device body, a cooling device installed on the top of the device body, a flue gas purification device installed on one side of the device body, a lower mold fixed inside the device body, an upper mold installed above the lower mold inside the device body, an exhaust fan installed on the top of the flue gas purification device, an exhaust pipe installed on the top of the flue gas purification device, an air supply pipe installed at the bottom of the flue gas purification device, an activated carbon filter installed inside the flue gas purification device, a pull plate fixed to the front end of the activated carbon filter, a housing fixed to one side of the flue gas purification device, a shaft rotating inside the housing, a limit block fixed to one end of the shaft, a sliding plate slidably connected inside the housing, an insert plate fixed to one side of the sliding plate, and a slot for cooperating with the insert plate on the surface of the pull plate.

[0006] Preferably, a second spring is fixed at both ends on one side of the movable plate, and the other end of the second spring is fixed to the housing.

[0007] Preferably, the limiting block is elliptical in shape, and the difference between the maximum and minimum diameters of the limiting block is greater than the distance the insert plate is inserted into the slot.

[0008] Preferably, a square rod is slidably connected inside the shaft, a knob is fixed to one end of the square rod, an insertion rod is fixed to one side of the knob, and an insertion hole for use with the insertion rod is opened on one side of the housing.

[0009] Preferably, both sides of the square rod are fixed with sliders, and both sides of the shaft body are provided with grooves that cooperate with the sliders.

[0010] Preferably, a first spring is fixed inside the shaft, and the other end of the first spring is fixed to a square rod.

[0011] Preferably, guide rods are fixed on both sides inside the housing, and grooves that cooperate with the guide rods are provided at both ends of the movable plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the structure of a shaft, a limiting block, a movable plate, an insert plate, a slot, a square rod, a knob, an insert rod, and an insertion hole allows the user to simply pull the knob to move the insert rod away from the insertion hole, and then turn the knob to engage with the square groove inside the shaft. This causes the square rod to rotate the shaft and the limiting block away from the movable plate. At this point, the movable plate is pushed by the rebound force of the second spring, removing the insert plate from the slot and releasing the fixing of the pull plate. This facilitates the user's maintenance or replacement of the activated carbon filter, improving purification efficiency. The operation is simple, requires no special tools, and is highly efficient.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-5 As shown, this utility model provides a technical solution: a rapidly cooling plastic particle heating and compression device, including a device body 1, a cooling device 2 installed on the top of the device body 1, a flue gas purification device 3 installed on one side of the device body 1, a lower mold 4 fixed inside the device body 1, an upper mold 5 installed above the lower mold 4 inside the device body 1, a vacuum pump 6 installed on the top of the flue gas purification device 3, an exhaust pipe 7 installed on the top of the flue gas purification device 3, an air supply pipe 8 installed at the bottom of the flue gas purification device 3, an activated carbon filter 9 installed inside the flue gas purification device 3, a pull plate 10 fixed to the front end of the activated carbon filter 9, a housing 11 fixed to one side of the flue gas purification device 3, a shaft 13 rotating inside the housing 11, a limit block 14 fixed to one end of the shaft 13, a movable plate 15 slidably connected inside the housing 11, an insert plate 16 fixed to one side of the movable plate 15, a slot 17 for cooperating with the insert plate 16 opened on the surface of the pull plate 10, and two ends of one side of the movable plate 15... Each component is fixed with a second spring 25, the other end of which is fixed to the housing 11. A square rod 18 is slidably connected inside the shaft 13. A knob 19 is fixed to one end of the square rod 18, and a plug rod 20 is fixed to one side of the knob 19. A plug hole 21 for use with the plug rod 20 is opened on one side of the housing 11. Through the structure of the shaft 13, the limiting block 14, the moving plate 15, the plug plate 16, the slot 17, the square rod 18, the knob 19, the plug rod 20, and the plug hole 21, the user only needs to pull the knob. 19. Move the insertion rod 20 away from the inside of the insertion hole 21, and then turn the knob 19. This will engage with the square groove inside the shaft 13, causing the square rod 18 to rotate the shaft 13 and the limiting block 14 away from the moving plate 15. At this time, the moving plate 15 will be pushed by the rebound force of the second spring 25, which will remove the insertion plate 16 from the slot 17. This will release the fixation of the pull plate 10, making it easier for the user to maintain or replace the activated carbon filter 9, improving purification efficiency. The operation is simple, requires no special tools, and is highly efficient.

[0022] Reference Figure 5 As shown in this embodiment: the limiting block 14 is elliptical in shape, and the difference between the maximum diameter and the minimum diameter of the limiting block 14 is greater than the distance that the insert plate 16 is inserted into the slot 17. Due to the elliptical nature of the limiting block 14, the moving distance of the moving plate 15 can completely remove the insert plate 16 from the inside of the slot 17, thus avoiding jamming.

[0023] Reference Figure 5 As shown in this embodiment: sliders 22 are fixed on both sides of the square rod 18, and grooves 23 that cooperate with the sliders 22 are opened on both sides of the shaft body 13. Through the structure of the sliders 22 and the grooves 23, it is possible to prevent the user from using too much force when pulling the knob 19, which would cause the square rod 18 to detach from the inside of the shaft body 13 and affect the fixing effect.

[0024] Reference Figure 5 As shown in this embodiment: a first spring 24 is fixed inside the shaft 13, and the other end of the first spring 24 is fixed to the square rod 18. Through the setting of the first spring 24, the first spring 24 is stretched during the disassembly of the activated carbon filter 9. When the new activated carbon filter 9 is installed, the rebound force of the first spring 24 makes it easy to fix and constrain the position of the knob 19.

[0025] Reference Figure 5 As shown in this embodiment: guide rods 26 are fixed on both sides inside the housing 11, and grooves 27 that cooperate with the guide rods 26 are opened at both ends of the moving plate 15. Through the structure of the guide rods 26 and the grooves 27, the movement trajectory of the moving plate 15 can be restricted to prevent it from deviating during movement.

[0026] Working principle: The user utilizes the structure of shaft 13, limiting block 14, moving plate 15, insert plate 16, slot 17, square rod 18, knob 19, insert rod 20, and insertion hole 21. The user simply pulls knob 19 to move insert rod 20 away from the insertion hole 21, then turns knob 19. This, in conjunction with the square groove inside shaft 13, causes square rod 18 to rotate shaft 13 and limiting block 14, moving them away from moving plate 15. At this point, moving plate 15 is pushed by the rebound force of second spring 25, removing insert plate 16 from slot 17, thus releasing the fixing of pull plate 10. This facilitates maintenance or replacement of activated carbon filter 9, improving purification efficiency. The operation is simple, requires no special tools, and is highly efficient. The elliptical shape of limiting block 14... The circular shape allows the moving plate 15 to completely remove the insert plate 16 from the slot 17, preventing jamming. The structure of the slider 22 and the groove 23 prevents the user from pulling the knob 19 too forcefully, causing the square rod 18 to disengage from the shaft 13 and affecting the fixing effect. The first spring 24 is stretched during the disassembly of the activated carbon filter 9. When a new activated carbon filter 9 is installed, the rebound force of the first spring 24 helps to fix and constrain the position of the knob 19. The structure of the guide rod 26 and the groove 27 restricts the movement trajectory of the moving plate 15, preventing it from deviating during movement.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
