Description
Technical Field
[0001] The present application relates to the technical field of plastic product processing, and in particular to a raw material softening device for plastic product processing. Background Art
[0002] When producing and processing some plastic products, it is often necessary to ensure the quality of the plastic products. Among them, the quality of the plastic raw materials is particularly important. Therefore, the plastic raw materials will be modified during the production process, and a softening process is also required during the modification process, which requires the addition of a certain amount of plasticizers and softeners for mixing.
[0003] Compared with the existing technology, some current softening devices need to be stirred and mixed with softeners during softening. During the stirring process, the plastic raw materials are prone to adhesion to the inside when stirred with the plasticizer softener. The adhesion of the raw materials to the internal structure may cause uneven softening areas in the plastic products, thereby affecting the overall quality and performance of the products. If the stirring and softening process becomes unsmooth, additional cleaning and repair work is required, thereby increasing production time and cost. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the present application provides a raw material softening device for plastic product processing, which has the advantages of improving softening quality, etc., and solves the problem that some existing softening devices need to be stirred and mixed with a softener during softening. During the stirring process, the plastic raw materials are easily adhered to the internal structure when stirred with the plasticizer softener. The adhesion of the raw materials to the internal structure may cause uneven softening areas in the plastic product, thereby affecting the overall quality and performance of the product. If the stirring and softening process becomes not smooth, additional cleaning and repair work is required, thereby increasing production time and cost.
[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a raw material softening device for processing plastic products, comprising an inner tank and an upper cover, wherein the bottom end of the inner tank is fixedly connected to a first motor, the bottom end of the inner tank is rotatably connected to a threaded rod, the upper end of the upper cover is fixedly connected to a second motor, the bottom end of the upper cover is rotatably connected to a rotating shaft, the outer wall of the rotating shaft is fixedly connected to a turntable, the outer wall of the turntable is fixedly connected to a first fixed rod, the bottom end of the outer wall of the rotating shaft is fixedly connected to a second fixed rod, one side of the first fixed rod is fixedly connected to a spiral stirring rod, and the ends of the first and second fixed rods away from the rotating shaft are fixedly connected to a scraper.
[0006] Through the above scheme, through the setting of the threaded rod, spiral stirring rod and scraper, the first motor drives the threaded rod to rotate to achieve overall stirring, and the second motor drives the rotating shaft and turntable, so that the spiral stirring rod stirs the raw materials more carefully in the vertical direction, ensuring that the raw materials and the plasticizer softener are evenly mixed. The scraper moves with the rotation of the turntable, which can effectively scrape off the residual raw materials on the inner wall of the inner tank to prevent the raw materials from sticking and accumulating on the inner wall, thereby ensuring the efficiency of stirring and softening. Since the device uses two independent motors to control the rotation of the threaded rod and the rotating shaft respectively, the stirring speed and direction can be adjusted according to actual needs to adapt to the softening requirements of plastic raw materials of different types and states.

[0008] Through the above scheme, the arrangement of the heating tubes enables the raw materials inside the inner tank to be heated evenly, avoiding the problem of inconsistent softening of the raw materials due to uneven heating. The outer shell can prevent the rapid loss of heat, improve the heating efficiency, and also ensure the temperature stability inside the inner tank, which is beneficial to the softening process of the raw materials.
[0009] Furthermore, a fixing plate is fixedly connected to the upper end of the outer wall of the shell, and a plurality of threaded holes arranged in a ring array are penetrated through the upper end of the fixing plate.

[0011] Furthermore, a discharge pipe is fixedly connected to one side of the bottom end of the inner tank, a chute is provided on the side of the discharge pipe away from the inner tank, and a plug is slidably provided inside the chute.
[0012] Through the above solution, the sliding design of the insert plate in the chute allows the user to control the opening and closing of the discharge pipe as needed. When the insert plate is fully inserted into the chute and blocks the discharge port, the discharge pipe is closed and the raw materials will not flow out; when the insert plate is partially or completely moved out of the chute, the discharge pipe is opened and the raw materials can flow out through the discharge pipe.
[0013] Furthermore, a thermometer and a feed hopper are fixedly connected to the upper end of the upper cover, and a sealing cover is slidably connected to the upper end of the feed hopper.
[0014] Through the above solution, the addition of a thermometer allows the user to monitor the temperature inside the inner tank in real time to ensure that the raw materials are softened at an appropriate temperature. The design of the feed hopper allows the user to easily add raw materials and plasticizers into the inner tank. The feed hopper is usually designed in a funnel shape, which can easily guide the raw materials into the inner tank while reducing the possibility of raw materials spilling. The sliding connection between the sealing cover and the feed hopper ensures the sealing of the feed port.
[0015] Furthermore, a mounting plate is fixedly connected to the bottom end of the outer wall of the upper cover, and a plurality of through holes arranged in a circular array are opened through the upper end of the mounting plate, and fixing bolts are slidably connected to the inside of the plurality of through holes, and one end of the plurality of fixing bolts passing through the through holes is threadedly connected to the threaded hole.
[0016] Through the above solution, a stable and reliable connection can be formed between the upper cover and the fixed plate through the threaded connection of the fixing bolts and the threaded holes, which can prevent the upper cover from loosening during the stirring and softening process and ensure the overall sealing of the equipment.
[0017] Furthermore, four supporting legs arranged in a rectangular array are fixedly connected to the bottom end of the inner tank.
[0018] Through the above solution, the four legs are arranged in a rectangular array, which can evenly distribute the weight of the inner tank, thereby ensuring that the inner tank can remain stable when placed or working, and is not prone to tipping or shaking.
[0019] Furthermore, the output end of the first motor passes through the bottom end of the inner tank and is fixedly connected to the threaded rod through a coupling, and the output end of the second motor passes through the upper end of the upper cover and is fixedly connected to the rotating shaft through a coupling.
[0020] Through the above solution, the first motor is used to drive the threaded rod to rotate, and the second motor is used to drive the rotating shaft to rotate.
[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:
[0022] This raw material softening device for processing plastic products is provided with a threaded rod, a spiral stirring rod and a scraper. The first motor drives the threaded rod to rotate to achieve overall stirring, while the second motor drives the rotating shaft and the turntable, so that the spiral stirring rod stirs the raw material more carefully in the vertical direction to ensure that the raw material and the plasticizer softener are evenly mixed. The scraper moves with the rotation of the turntable and can effectively scrape off the residual raw material on the inner wall of the inner tank to prevent the raw material from sticking and accumulating on the inner wall, thereby ensuring the efficiency of stirring and softening. Since the device adopts two independent motors to control the rotation of the threaded rod and the rotating shaft respectively, the stirring speed and direction can be adjusted according to actual needs to meet the softening requirements of plastic raw materials of different types and states.
