Description

Technical Field

[0001] The invention relates to the technical field of plastic production equipment, in particular to a cooling mechanism of a plastic extruder. Background Art

[0002] Most plastics have a series of advantages such as light weight, chemical stability, no rust, good impact resistance, good transparency and wear resistance, good insulation, good colorability, low processing cost, etc. Therefore, they are widely used in daily life and industrial production. Different plastics can be divided into thermoplastics and thermosetting according to their different physical and chemical properties. The processing technology of thermoplastics is mostly extrusion. Plastic extruder is a machine that extrude plastic raw materials from the extruder under high extrusion pressure and then cools and forms them. After leaving the head, the plastic should be cooled and formed immediately, otherwise it will deform under the action of gravity. The main machine of the plastic extruder is an extruder, which is composed of an extrusion system, a transmission system and a heating and cooling system.

[0003] After plastic molding, it is generally necessary to cool and shape it, otherwise it will be deformed due to gravity and affect the final shape. The common existing cooling method is cooling by immersion in water. When the injection molding device starts to work, it often lasts for a long time. As the number of times the molded plastic is immersed in water increases, the water temperature in the pool will continue to rise, which makes the replacement of the pool water frequent, and the consumption of water resources will become extremely large; at the same time, some plastics carry a certain amount of toxic substances after cooling and molding, and the staff will inevitably accumulate a certain amount of toxins in the human body when they are in contact with such plastic products for a long time, which has an adverse effect on the health of the staff; and the plastic products cooled by the pool water need to be salvaged by the staff, and the more the number of cooled plastic products, the more times they are salvaged, which will greatly increase the work intensity of the staff and cause a decrease in subsequent work efficiency; for this reason, we propose a cooling mechanism for a plastic extruder.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a cooling mechanism for a plastic extruder, which has the following features:

[0020] Beneficial effects:

[0021] 1. The cooling mechanism of the plastic extruder accelerates the frequency of contact between the cold airflow and the finished thermoplastic product by using a refrigerator and a fan. When the finished plastic product is still in the plastic ring groove, the continuous erosion of the cold airflow prevents the finished plastic product from being deformed due to the loss of the plastic ring groove when it is ejected by the ejection assembly, and is continuously cooled by cold air during the process from being ejected to being fully formed and conveyed. This process no longer requires cooling by immersion in water, which reduces the use of water resources, greatly saves water resources, and does not need to consider the problem of wastewater discharge, streamlining the subsequent processing process.

[0022] 2. The cooling mechanism of the plastic extruder cleans a large amount of toxic substances on the finished plastic products through the disinfection component, and is equipped with a cleaning and drying device for the finished plastic products at the outlet to further treat the disinfectant water to ensure that the finished plastic products enter the predetermined storage box after drying. The toxic substances in the disinfected plastic components themselves are greatly reduced, ensuring that the health of the staff will not be negatively affected when they come into contact with them.

[0023] 3. The cooling mechanism of the plastic extruder can be seen from the entire mechanism itself. The No. 1 conveying component initially conveys the finished plastic products, and the ejection mechanism ejects the finished plastic products into the No. 2 conveying component, and the finished plastic products are cooled, disinfected, cleaned and dried until they are automatically put into the storage box. The whole process is automated. Only when the storage box is full will the staff move it away. Therefore, it greatly simplifies the repetitive work of the staff and improves the work efficiency of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Working principle:

[0048] Before use, start the No. 2 conveying component 5, and then pour the plastic solution into the plastic ring groove 33 through the extruder, and the ejector component 4 is installed in the plastic ring groove 33, and the plastic ring tool 41 is just clamped in the plastic ring groove 33 to form the bottom surface of the mold. When the pouring is completed, the mounting groove 42 is clamped with the receiving support plate 34 to form a support point, and then the conveyor belt 32 will drive the finished plastic product in the plastic ring groove 33 to move to the No. 2 conveying component 5, move a distance until the next plastic ring groove 33 is docked with the extruder. As the plastic ring groove 42 filled with the finished plastic product approaches the inclined transmission belt 51, the cold air in the refrigerator 61 also contacts the finished plastic product in the plastic ring groove 33 under the action of the airflow of the fan, and cools it down to prevent deformation during the ejection process. At this time, the ejector component 4 The top plate 43 approaches the transmission shaft 31 during the movement. When the top plate 43 starts to contact, it moves upward under the contact of the transmission shaft 31, so that the ejector assembly moves upward as a whole in this process. The plastic ring 41 will completely eject the finished plastic product in the plastic ring groove 33. At this time, the ejector assembly 4 completely enters the No. 1 conveying assembly 3 to avoid the subsequent jamming of other components. At this time, the finished plastic product is conveyed to the inclined conveying belt 51 through the No. 1 conveying assembly 3. Before moving to the output conveyor belt 54, the finished plastic product will be continuously cooled by cold air to ensure that the finished plastic product is completely shaped. In this cooling process, the traditional water immersion cooling is abandoned, the consumption of water resources is reduced, water resources are greatly saved, and the cost of using water resources is reduced;

[0049] As the cooled finished plastic product is transferred to the output conveyor belt 54, in order to prevent the toxic substances on the finished plastic product from affecting the staff, the disinfection component 7 arranged directly above it is opened, and the disinfectant stored in the disinfector 71 enters the shower head at the bottom through the disinfection tube 72, and finally the disinfectant is sprayed on the finished plastic product through the shower head 73 to achieve the purpose of disinfection. The toxic substances in the plastic component itself after disinfection will be greatly reduced, further reducing the impact on the health of the staff when they come into contact with it. The disinfectant sprayed on the output conveyor belt 54 will contact the cleaning sponge 95 arranged directly below it under the drive of the docking shaft 52, so that the disinfectant on the surface of the output conveyor belt 54 is wiped off, ensuring that the next finished plastic product on the output conveyor belt 54 will not be affected after each disinfection.

[0050] When the finished plastic product is disinfected, it will enter the discharge position of the outlet. At this time, the drying components 8 set on both sides will start to start. As the finished plastic product moves outward, it begins to contact the drying sponge 84. As the driving motor 81 starts, the driving shaft 82 starts to rotate, and drives the built-in rotating block 83 to rotate. The drying sponge 84 installed on the outer ring of the built-in rotating block 83 rotates with its rotation, thereby continuously cleaning and absorbing the disinfectant on the surface of the finished plastic product. After cleaning, it falls into the storage box prepared in advance along the inclined slope of the outlet and is taken away by the staff after it is full. The whole process is autonomously controlled by the device, which greatly simplifies the repetitive work of the staff and improves the work efficiency of the staff.
