Description

Technical Field

[0001] The utility model relates to the technical field of heating and compressing plastic particles, and more specifically, to a plastic particle heating and compressing device with a rapid cooling mechanism. Background Art

[0002] Plastic particles are semi-finished products of plastic materials, widely used for storage, transportation and further processing. They are polymer compounds generated by polymerization reactions of basic chemicals extracted from petrochemical products. These polymers undergo specific processing, such as pelletizing, to be made into particles of relatively uniform size for easy management and use. The cooling effect of some existing plastic particle heating and compression equipment exists in the form of air cooling for heat dissipation. Simple air cooling is difficult to take away heat quickly, especially in the high temperature environment in summer, and the efficiency is poor.

[0003] In order to solve the above problems, the publication number CN220517370U discloses "a plastic particle heating and compression device that can quickly cool down". Through the electric push rod, heating mechanism, lower pressing plate, electric heating tube, heat-conducting pressing plate, cover plate, frame plate and cooling mechanism, by opening the water valve, the water flows along the first hose and the second hose, and enters the water flow groove on the lower pressing plate from the first hose, increasing the contact area with the lower pressing plate, increasing the cooling effect, and at the same time, the water flows along the second hose into the interior of the water storage box, and the water storage box directly contacts the frame plate, which can take away the heat on the frame plate. In the above manner, the heat can be taken away by water cooling after the hot pressing is completed. However, the device still has certain defects in actual use. For example, the cooling water used by the device needs to be collected by a bucket first and then reused, and the cooling water cannot be continuously circulated, which will increase the work content of the staff. When the pressing plate presses the plastic particles, if the air inside the loading frame cannot be discharged, the air will enter the molded plastic product, resulting in a cavity inside the plastic product.

[0023] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 6 As shown:

[0026] The utility model provides a plastic particle heating and compression device with a rapid cooling mechanism, comprising a bottom plate 1; a top plate 101 is connected to the top of the bottom plate 1 through a support, a loading frame 2 is provided on the upper surface of the bottom plate 1, a pressing plate 3 is provided at the bottom of the top plate 101, a heating pipe 301 is provided inside the pressing plate 3, an exhaust component is provided inside the pressing plate 3 for exhausting the air inside the loading frame 2, and a cooling component is provided at the bottom of the loading frame 2 for cooling the plastic particles.

[0027] Among them, telescopic cylinders 102 are installed on both sides of the bottom of the top plate 101, and a telescopic rod 103 is provided at the bottom of the telescopic cylinder 102, and the telescopic rod 103 is fixedly connected to the pressing plate 3. When the plastic particles are heated and compressed, the plastic particles are poured into the loading frame 2, and the cylinder 102 is started through the control panel, so that the telescopic rod 103 pushes the pressing plate 3 into the loading frame 2 and then the heating tube 301 is started to increase the temperature of the bottom of the pressing plate 3, thereby melting the plastic particles and compressing them into shape.

[0028] Among them, the exhaust component includes: an exhaust hole 302, a sealing plate 303 and a sealing block 304. Exhaust holes 302 are opened on the four sides of the pressure plate 3. A sealing plate 303 is provided on the top of the exhaust hole 302. A matching sealing block 304 is provided inside the exhaust hole 302, and the sealing block 304 is connected to the sealing plate 303. Springs 305 are connected on both sides of the bottom of the sealing plate 303. Grooves 306 are opened on both sides of the outer end of the exhaust hole 302, and the spring 305 is fixedly connected to the bottom of the groove 306.

[0029] When the pressing plate 3 enters the loading frame 2 to heat and compress the plastic particles, the air inside the loading frame 2 will be squeezed when the pressing plate 3 enters the loading frame 2. At this time, the air will fill the exhaust hole 302. After the air pressure inside the loading frame 2 gradually increases, the air will push the sealing block 304 and the sealing plate 303 to move upward, so that the sealing plate 303 pulls the spring 305 and makes the sealing block 304 disengage from the exhaust hole 302, so that the air inside the loading frame 2 can be discharged from the exhaust hole 302, avoiding the air inside the loading frame 2 from remaining inside the molded plastic product, resulting in a cavity inside the plastic product. After the air inside the loading frame 2 is discharged, the thrust on the sealing block 304 generated by the internal air pressure will disappear. At this time, the previously stretched spring 305 will shrink and reset, thereby driving the sealing plate 303 and the sealing block 304 to move downward, so that the sealing block 304 reseals the exhaust hole 302.

[0030] When the plastic product is pressed, the excess plastic raw material will enter the exhaust hole 302 and be cooled and formed, and can be discarded after the plastic product is taken out.

[0031] Among them, the cooling component includes: a cooling chamber 201, a water tank 4, an output pump 401, a circulation pump 402, an output pipe 202 and a circulation pipe 203. A cooling chamber 201 is opened at the bottom of the loading frame 2, and a water tank 4 is provided on the top of the top plate 101. The output pump 401 and the circulation pump 402 are respectively installed on both sides of the outer end of the water tank 4. The output pipe 202 and the circulation pipe 203 are respectively connected to both sides of the outer end of the cooling chamber 201, and the output pipe 202 is communicated with the output pump 401, and the circulation pipe 203 is communicated with the circulation pump 402.

[0032] After the plastic product is pressed and formed inside the loading frame 2, the output pump 401 and the circulation pump 402 are started through the control panel. At this time, the output pump 401 extracts the coolant from the water tank 4 and inputs the coolant into the cooling chamber 201 through the output pipe 202. The coolant absorbs the internal heat of the loading frame 2 to quickly cool the molded plastic product. Then the circulation pump 402 extracts the coolant entering the cooling chamber 201 through the circulation pipe 203 and re-injects it into the water tank 1, so that the coolant can be recycled, and the circulating flow of the coolant can ensure its cooling effect and avoid the temperature of the coolant from rising.

[0033] Among them, an opening is opened on the top of the water tank 4, and a heat dissipation frame 5 is arranged inside the opening. A plurality of heat dissipation fins 501 are arranged at the bottom of the heat dissipation frame 5, and two heat dissipation fans 502 are installed on the top of the heat dissipation frame 5. The heat dissipation fins 501 at the bottom of the heat dissipation frame 5 absorb the heat of the coolant and dissipate the heat outward, thereby cooling the coolant. The heat dissipation fan 502 is started through the control panel, so that the heat dissipated by the heat dissipation fins 501 is quickly discharged to the outside by using the heat dissipation fan 501, so that the cooling effect of the heat dissipation fins 501 on the coolant is improved. Cooling the coolant can improve the ability of the coolant to absorb heat inside the cooling chamber 201, thereby improving the cooling efficiency of the plastic product.

[0034] A dustproof net 503 is installed on the top of the heat dissipation frame 5, and the dustproof net 503 is a high-density filter. The dustproof net 503 on the top of the heat dissipation frame 5 can prevent dust from contacting the coolant through the heat dissipation frame 5.

[0035] A control panel is installed on the top of the top plate 101, and the control panel is used to start and shut down the telescopic cylinder 101, the output pump 401, the circulating pump 402 and the cooling fan 502. The control panel, the telescopic cylinder 101, the output pump 401, the circulating pump 402 and the cooling fan 502 are all powered by an external power supply, and the control procedures involved in the utility model can be implemented by those skilled in the art according to the same or similar principles in the prior art, and this part is not the innovation of the utility model.

[0036] The specific usage and function of this embodiment are as follows:

[0037] When the pressing plate 3 enters the loading frame 2 to heat and compress the plastic particles, the air inside the loading frame 2 will be squeezed when the pressing plate 3 enters the loading frame 2. At this time, the air will fill the exhaust hole 302. After the air pressure inside the loading frame 2 gradually increases, the air will push the sealing block 304 and the sealing plate 303 to move upward, so that the sealing plate 303 pulls the spring 305 and makes the sealing block 304 disengage from the exhaust hole 302, so that the air inside the loading frame 2 can be discharged from the exhaust hole 302, avoiding the air inside the loading frame 2 from remaining inside the molded plastic product, resulting in a cavity inside the plastic product. After the air inside the loading frame 2 is discharged, the thrust on the sealing block 304 generated by the internal air pressure will disappear. At this time, the previously stretched spring 305 will shrink and reset, thereby driving the sealing plate 303 and the sealing block 304 to move downward, so that the sealing block 304 reseals the exhaust hole 302.

[0038] After the plastic product is pressed and formed inside the loading frame 2, the output pump 401 and the circulation pump 402 are started through the control panel. At this time, the output pump 401 extracts the coolant from the water tank 4 and inputs the coolant into the cooling chamber 201 through the output pipe 202. The coolant absorbs the internal heat of the loading frame 2 to quickly cool the molded plastic product. Then the circulation pump 402 extracts the coolant entering the cooling chamber 201 through the circulation pipe 203 and re-injects it into the water tank 1, so that the coolant can be recycled, and the circulating flow of the coolant can ensure its cooling effect and avoid the temperature of the coolant from rising.
