Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a plastic processing mixing machine with temperature control function. Background Technology

[0002] In the plastics processing industry, the mixing of plastic raw materials is a crucial step. Different plastic raw materials have different physical and chemical properties. How to fully mix these raw materials to achieve a uniform state is a challenge. Therefore, plastic processing mixing machines with temperature control functions have emerged. These mixing machines can not only force the mixing of plastic raw materials, but also precisely control the temperature during the mixing process, thereby ensuring the quality and uniformity of the mixture.

[0003] A Chinese patent discloses a plastic processing mixing machine with a material cleaning function (authorization announcement number CN219028053U). This patented technology solves the problem that in conventional plastic mixing machines, a small amount of residual material often remains inside the machine at the end of the discharge stage and cannot flow out. Manual cleaning poses certain safety risks, while not cleaning will result in product waste and increased manufacturing costs.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Existing plastic processing mixing machines with temperature control functions cannot accurately control the material discharge speed during use. As a result, if the discharge speed is too fast during the mixing process, the internal pressure of the mixing machine will suddenly drop, thus affecting the mixing effect and the stability of temperature control. Conversely, if the discharge speed is too slow, the mixing machine will experience overheating or material deterioration due to the material residence time being too long, reducing the overall production efficiency and increasing the labor intensity of the operator. Utility Model Content

[0005] The technical problem to be solved by this utility model is that existing plastic processing mixers with temperature control function have the disadvantage that they cannot accurately control the discharge speed of materials during use. Therefore, we propose a plastic processing mixer with temperature control function.

[0006] To achieve the above objectives, this application adopts the following technical solution: a plastic processing mixing machine with temperature control function, comprising a tank body, a tank cover at the top of the tank body, multiple support legs fixed at the bottom of the tank body, a temperature control device installed on the outer surface of the tank body, a stirring shaft rotatably connected through the inside of the tank body, multiple stirring paddles fixed on the surface of the stirring shaft, a discharge pipe at the bottom of the tank body, a first drive motor installed at the bottom of the stirring shaft, a housing fixed on the surface of the discharge pipe, a baffle plate slidably connected inside the housing and the discharge pipe, a pull rope fixed at one end of the baffle plate, a take-up reel wound around the other end of the pull rope, and a second drive motor installed at one end of the take-up reel.

[0007] Preferably, pull ropes are fixed on both sides of the baffle plate, and through holes are provided on both sides of the housing for sliding connection with the pull rod.

[0008] Preferably, L-shaped plates are slidably connected to both sides of the housing, and one side of the L-shaped plate is fixed to the pull rod.

[0009] Preferably, a return spring is fixed on both sides of the housing, and the other end of the return spring is fixed to the L-shaped plate.

[0010] Preferably, the housing has a sealing groove inside, and the inside of the sealing groove is slidably connected to the baffle plate.

[0011] Preferably, a sensor device is installed at the bottom of the tank near the discharge pipe, and the sensor device is electrically connected to the second drive motor.

[0012] Preferably, the surface of the stirring shaft is fixed with multiple scrapers at the bottom of the stirring paddle, and the scrapers are distributed in a circumferential manner.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, a first drive motor drives a stirring shaft to rotate a stirring paddle, continuously throwing material particles into various corners of the tank to achieve mixing. A temperature control device precisely controls the temperature inside the tank. When it is necessary to discharge the mixed plastic from the tank, a sensor device controls a second drive motor to start and drive a winding wheel to rotate, causing the pull rope to wind up on the surface of the winding wheel. With the pull rope taut, the baffle plate is pulled to adjust the diameter of the discharge pipe, thereby achieving precise control of the discharge speed of the material particles. By precisely controlling the discharge speed, the temperature of the material can be kept stable during the discharge process, avoiding a sudden drop in temperature due to excessively fast discharge or overheating of the material due to excessively slow discharge. This ensures the stable quality of the plastic mixture, reduces manual operation, and improves production efficiency. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Reference Figures 1-5As shown, this utility model provides a technical solution: a plastic processing mixing machine with temperature control function, including a tank 1, a tank cover 2 on the top of the tank 1, multiple support legs 3 fixed at the bottom of the tank 1, a temperature control device 4 installed on the outer surface of the tank 1, a stirring shaft 5 rotatably connected through the inside of the tank 1, multiple stirring paddles 6 fixed on the surface of the stirring shaft 5, a discharge pipe 7 at the bottom of the tank 1, a first drive motor 8 installed at the bottom of the stirring shaft 5, a housing 9 fixed on the surface of the discharge pipe 7, a baffle plate 10 slidably connected inside the housing 9 and the discharge pipe 7, a pull rope 11 fixed at one end of the baffle plate 10, a winding wheel 12 wound around the other end of the pull rope 11, a second drive motor 13 installed at one end of the winding wheel 12, and a sensor device 19 installed at the bottom of the tank 1 near the discharge pipe 7, the sensor device 19 and the second drive motor 13 being electrically connected. The system connects to the mixing tank 1. The first drive motor 8 drives the stirring shaft 5 to rotate the stirring paddle 6, continuously throwing the material particles into various corners of the tank 1 to achieve mixing. The temperature control device 4 can precisely control the temperature inside the tank 1. When it is necessary to discharge the mixed plastic inside the tank 1, the sensor device 19 controls the second drive motor 13 to start and drive the winding wheel 12 to rotate, so that the pull rope 11 is wound on the surface of the winding wheel 12. The pull rope 11 is in a taut state, pulling the baffle plate 10 to adjust the diameter of the discharge pipe 7, thereby achieving precise control of the discharge speed of the material particles. By precisely controlling the discharge speed, the temperature of the material can be kept stable during the discharge process, avoiding a sudden drop in temperature due to excessively fast discharge or overheating of the material due to excessively slow discharge, thus ensuring the stable quality of the plastic mixture, reducing manual operation, and improving production efficiency.

[0023] Reference Figure 4 and Figure 5 As shown in this embodiment: Pull ropes 11 are fixed to both sides of the baffle plate 10; through holes 15 are provided on both sides of the housing 9 for sliding connection with the pull rod 14; L-shaped plates 16 are slidably connected to both sides of the housing 9, one side of the L-shaped plate 16 is fixed to the pull rod 14; return springs 17 are fixed to both sides of the housing 9, the other end of the return spring 17 is fixed to the L-shaped plate 16; a sealing groove 18 is provided inside the housing 9, and the interior of the sealing groove 18 is slidably connected to the baffle plate 10. When the discharge of material particles inside the tank 1 is controlled, the baffle plate... When the plate 10 is pulled, it will cause the pull rod 14 to slide outward together. The pull rod 14 and the through hole 15 work together to limit the movement trajectory of the baffle plate 10 and prevent tilting. When it is necessary to stop the discharge, the sensor device 19 controls the second drive motor 13 to rotate in the opposite direction. The pull rope 11 is in a relaxed state. The rebound force of the return spring 17 pulls the L-shaped plate 16 and the pull rod 14 to drive the baffle plate 10 to return to the inside of the sealing groove 18, improve the sealing between the discharge pipe 7 and the housing 9, and reduce material waste.

[0024] Reference Figure 2 As shown in this embodiment: multiple scrapers 20 are fixed on the surface of the stirring shaft 5 at the bottom of the stirring paddle 6. The scrapers 20 are distributed in a circle. By setting the scrapers 20, the material can be prevented from accumulating at the bottom of the tank 1, which would affect the discharge effect.

[0025] The specific operating steps for this plastic processing mixing machine with temperature control function are as follows:

[0026] First, the first drive motor 8 drives the stirring shaft 5 to rotate the stirring paddle 6, continuously throwing the material particles into various corners of the tank 1 to achieve the purpose of mixing. The temperature control device 4 can accurately control the temperature inside the tank 1. When it is necessary to discharge the mixed plastic inside the tank 1, the sensor device 19 controls the second drive motor 13 to start and drive the winding wheel 12 to rotate, so that the pull rope 11 is wound on the surface of the winding wheel 12. The pull rope 11 is in a taut state, pulling the baffle plate 10 to adjust the diameter of the discharge pipe 7, thereby achieving precise control of the discharge speed of the material particles. By accurately controlling the discharge speed, the temperature of the material can be kept stable during the discharge process, avoiding the sudden drop in temperature caused by too fast discharge or the overheating of the material caused by too slow discharge, thereby ensuring the stable quality of the plastic mixture, reducing manual operation, and improving production efficiency.

[0027] 2. When the material particles inside the tank 1 are discharged, the baffle plate 10 is pulled, which in turn drives the pull rod 14 to slide outward. The pull rod 14 and the through hole 15 work together to limit the movement trajectory of the baffle plate 10 and prevent tilting. When it is necessary to stop the discharge, the sensor device 19 controls the second drive motor 13 to rotate in the opposite direction. The pull rope 11 is in a relaxed state. The rebound force of the return spring 17 pulls the L-shaped plate 16 and the pull rod 14 to drive the baffle plate 10 back to the inside of the sealing groove 18, which improves the sealing between the discharge pipe 7 and the shell 9 and reduces material waste.

[0028] Third, by setting scraper 20, it is possible to prevent materials from accumulating at the bottom of the tank 1, which would affect the discharge effect.

[0029] 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.
