Description

Technical Field

[0001] This utility model belongs to the field of internal mixer technology, specifically referring to a material push-pull device for a drop-type internal mixer. Background Technology

[0002] A closed-type plastic mixer, also known as an internal mixer, is mainly composed of a mixing chamber, also called a plasticizing chamber. The upper part houses the feeding device, and the lower part is the discharge port, with a bolt at both the top and bottom. When the upper and lower bolts are closed, a closed plasticizing chamber is formed. Inside the plasticizing chamber are a pair of rotors rotating in opposite directions. The rotors have a pear-shaped cross-section and a Z-shaped spiral along the longitudinal direction. The rotors rotate at slightly different speeds, maintaining a constant speed ratio between them and between the rotors and the inner wall of the plasticizing chamber. The outer wall of the plasticizing chamber has a cooling (heating) jacket for heating and cooling the material. In contrast, in a drop-type internal mixer, the material falls in a long strip into the lifting hopper during the discharge process. After the descent, the material tilts to one side due to inertia, scraping against the crossbeam and picking up impurities.

[0003] Chinese Patent No. CN213890771U discloses a material push-pull device for a drop-type internal mixer. This device utilizes a hydraulic press, a telescopic rod, a material push plate, and a movable plate. The hydraulic press pulls the telescopic rod in a reciprocating motion, which in turn causes the material push plate to move synchronously. The material push plate can be adjusted to any angle using the movable plate. Through the combined action of a fixed plate, a fixed hole, an internal threaded hole, and a fixing screw, maintenance can be performed by loosening the fixing screw, unscrewing it from the internal threaded hole, and then removing it from the fixed hole. This allows the part connecting the material push plate to the hydraulic press to be disassembled for easy maintenance and replacement.

[0004] However, the above-mentioned device is troublesome to adjust the three movable plates according to the needs, making it inconvenient to use. Utility Model Content

[0005] The problem this utility model aims to solve is that adjusting multiple movable plates is troublesome and inconvenient.

[0006] To solve the above-mentioned technical problems, this utility model proposes a material push-pull device for a drop-type internal mixer, including a support platform frame, a material side baffle, a bottom plate, a support column, a push-pull device, a limiting device, and a receiving device. The material side baffle is fixed to the lower side of the support platform frame, the bottom plate is located below the material side baffle, the support column is erected at one end of the bottom plate, the push-pull device is fixed to one side of the support platform frame, the limiting device is located on the push-pull device, and the receiving device is located on the upper side of the bottom plate.

[0007] Furthermore, the push-pull device includes a mounting frame, a motor, a lead screw, a threaded slide rod, and an inclined baffle. The mounting frame is fixed to one side of the support platform frame. The motor is fixed to the support column and its output shaft passes through the mounting frame. One end of the lead screw is fixed to the output shaft of the motor, and the other end is rotatably mounted on the support platform frame. The threaded slide rod is threadedly connected to the lead screw, and the inclined baffle is fixed to the threaded slide rod.

[0008] Furthermore, the limiting device includes a T-shaped groove and a T-shaped slider. The T-shaped groove is located inside the mounting frame, and the T-shaped slider is slidably disposed on the T-shaped groove. The two ends of the threaded slide rod are respectively fixed on the T-shaped slider.

[0009] Furthermore, the receiving device includes an electric telescopic rod, a fixed plate, and a receiving groove. The electric telescopic rod is fixed to the base plate, the fixed plate is fixed to the telescopic end of the electric telescopic rod, and the receiving groove is located on the upper side of the fixed plate.

[0010] Furthermore, the receiving trough is located directly below the support platform frame.

[0011] Furthermore, when the threaded slide rod does not drive the inclined baffle to move, there is a distance between the inclined baffle and the material side baffle. 。

[0012] The beneficial effects of this utility model by adopting the above structure are as follows:

[0013] By running the motor, the threaded slide bar slides on the lead screw, thereby driving the inclined baffle to move slowly, allowing the material to slowly fall into the receiving trough, solving the problem of the troublesome and inconvenient use of adjusting multiple movable plates.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, the present invention proposes a material push-pull device for a drop-type internal mixer, including a support platform frame 1, a material side baffle 2, a bottom plate 3, a support column 4, a push-pull device 5, a limiting device 6, and a receiving device 7. The material side baffle 2 is fixed to the lower side of the support platform frame 1, the bottom plate 3 is located below the material side baffle 2, the support column 4 is erected at one end of the bottom plate 3, the push-pull device 5 is fixed to one side of the support platform frame 1, the limiting device 6 is located on the push-pull device 5, and the receiving device 7 is located on the upper side of the bottom plate 3.

[0022] As per the instruction manual Figure 2 As shown, to prevent materials from touching other parts and getting contaminated with impurities during feeding, the push-pull device 5 includes a mounting frame 8, a motor 9, a lead screw 10, a threaded slide rod 11, and an inclined baffle 12. The mounting frame 8 is fixed to one side of the support platform frame 1. The motor 9 is fixed to the support column 4, and its output shaft passes through the mounting frame 8. One end of the lead screw 10 is fixed to the output shaft of the motor 9, and the other end is rotatably mounted on the support platform frame 1. The threaded slide rod 11 is threadedly connected to the lead screw 10. The inclined baffle 12 is fixed to the threaded slide rod 11. When the threaded slide rod 11 does not drive the inclined baffle 12 to move, there is a distance between the inclined baffle 12 and the material side baffle 2.

[0023] As per the instruction manual Figure 4 As shown, in order to limit the threaded slide bar 11, the limiting device 6 includes a T-shaped slide groove 13 and a T-shaped slider 14. The T-shaped slide groove 13 is located inside the mounting bracket 8, and the T-shaped slider 14 is slidably located on the T-shaped slide groove 13. The two ends of the threaded slide bar 11 are respectively fixed on the T-shaped slider 14.

[0024] As per the instruction manual Figure 1 , 3 As shown, in order to accommodate materials of different volumes, the receiving device 7 includes an electric telescopic rod 15, a fixed plate 16, and a receiving trough 17. The electric telescopic rod 15 is fixed on the base plate 3, the fixed plate 16 is fixed on the telescopic end of the electric telescopic rod 15, and the receiving trough 17 is located on the upper side of the fixed plate 16 and directly below the support platform frame 1.

[0025] In practical use, the support platform frame 1 is fixed at the discharge port of the drop mixer. According to the amount of raw materials added, the electric telescopic rod 15 is operated to adjust the distance between the receiving trough 17 and the material side baffle 2. When the material falls, it falls between the material side baffle 2 and the inclined baffle 12. Since there is a distance between the inclined baffle 12 and the material side baffle 2, one side of the material first contacts one end of the receiving trough 17. The motor 9 is run so that the threaded slide rod 11 slides on the screw 10, thereby driving the inclined baffle 12 to move slowly, so that the material slowly falls into the receiving trough 17. The above is the usage process of the material push-pull device for the drop mixer.
