Description

Technical Field

[0001] This utility model relates to the field of rubber internal mixer technology, and specifically to a mixing and feeding mechanism for a rubber internal mixer. Background Technology

[0002] An internal mixer, also known as a kneading machine, is mainly used for plasticizing and mixing rubber. It is a mechanical device with a pair of rotors of a specific shape that rotate relative to each other. It intermittently plasticizes and mixes polymer materials in a closed state with adjustable temperature and pressure. It mainly consists of a mixing chamber, rotors, rotor end face sealing device, feeding and pressing device, unloading device, transmission device and machine base. The mixing chamber, rotors and rotor end face sealing device are in contact with each other and are the most important factors affecting the mixing quality.

[0003] The feed hopper on the mixing chamber of the existing internal mixer is prone to clogging during feeding, resulting in low feeding efficiency and inconvenience in use. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a mixing and feeding mechanism for a rubber internal mixer, which solves the problem that the feed hopper on the mixing chamber of the existing internal mixer is prone to blockage during feeding, resulting in low feeding efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A mixing and feeding mechanism for a rubber internal mixer is provided, comprising a feeding hopper disposed at the top of the mixing chamber body and the top of the feeding hopper being connected to the top of the mixing chamber body; the bottom of the feeding hopper extending into the mixing chamber body, and an evacuation component being disposed in the bottom of the feeding hopper.

[0007] This utility model extends the bottom of the feeding hopper into the main body of the mixing chamber. When feeding rubber into the main body of the mixing chamber through the feeding hopper, the rubber feeding is dispersed by the dispersion component set at the bottom of the feeding hopper to prevent the rubber feeding from getting blocked and improve the feeding efficiency.

[0008] Furthermore, the feed hopper is tapered from top to bottom, and the bottom of the feed hopper is provided with an extension cylinder for installing the evacuation components, and the extension cylinder is placed inside the main body of the mixing chamber.

[0009] Furthermore, the evacuation component is a cone with a sharp tip.

[0010] Furthermore, the evacuation assembly includes a mounting box housed within the extension tube, with an evacuation component positioned above the mounting box.

[0011] Furthermore, multiple connecting rods are evenly arranged around the outer circumference of the mounting box, and the other end of the connecting rods is connected to the inner side of the extension cylinder. The mounting box is fixed in the middle of the extension cylinder by the multiple connecting rods.

[0012] Furthermore, a motor is installed inside the mounting box, and the output shaft of the motor passes through the mounting box and is connected to the bottom of the evacuation component.

[0013] Furthermore, several evacuation grooves are formed on the outer circumference of the cone, and these grooves are evenly arranged around the cone.

[0014] This utility model discloses a mixing and feeding mechanism for a rubber internal mixer, which has the following advantages:

[0015] 1. This utility model extends the bottom of the feeding hopper into the main body of the mixing chamber. When feeding rubber into the main body of the mixing chamber through the feeding hopper, the rubber feeding is dispersed by the dispersion component set at the bottom of the feeding hopper to prevent the rubber feeding from getting blocked and improve the feeding efficiency.

[0016] 2. The evacuation component in this utility model is a cone with a sharp top. When the rubber is fed, the sharp top of the cone breaks the falling rubber feed, thereby separating and evacuating the rubber feed, preventing the rubber feed from getting blocked, and ensuring that the feed smoothly enters the main body of the mixing chamber.

[0017] 3. This utility model has a evacuation groove on the evacuation component. At the same time, the evacuation component can be driven to rotate by a motor, thereby further separating and evacuating the falling rubber feed, preventing the rubber feed from getting blocked during feeding, and improving the feeding efficiency.

[0025] Example 1

[0026] This embodiment provides a mixing and feeding mechanism for a rubber internal mixer. Its purpose is to solve the problem of easy clogging of the feed hopper in the mixing chamber of existing internal mixers, resulting in low feeding efficiency. (Reference) Figures 1-5 The specific structure of this embodiment will be described in detail below.

[0027] A mixing and feeding mechanism for a rubber internal mixer, comprising a feed hopper 2.

[0028] The feeding hopper 2 is located at the top of the mixing chamber body 1, and the top of the feeding hopper 2 is connected to the top of the mixing chamber body 1. The bottom of the feeding hopper 2 extends into the mixing chamber body 1, and an evacuation component 3 is provided in the bottom of the feeding hopper 2.

[0029] Specifically, the feed hopper 2 is tapered from top to bottom, and the bottom of the feed hopper 2 is provided with an extension cylinder 21 for installing the evacuation assembly 3, and the extension cylinder 21 is placed inside the main body 1 of the mixing chamber.

[0030] In this embodiment, the feeding hopper 2 is set at the top of the mixing chamber body 1, and the bottom of the feeding hopper 2 extends into the mixing chamber body 1. An extension cylinder 21 is connected to the extension, and the dispersion component 3 is installed at the middle position of the extension cylinder 21. Thus, when rubber is fed into the mixing chamber body 1 through the feeding hopper 2, the rubber feed is dispersed by the dispersion component 3 set at the bottom of the feeding hopper 2, preventing the rubber feed from getting blocked during feeding, ensuring the smooth passage of the rubber feed, and improving the feeding efficiency.

[0031] Specifically, the evacuation assembly 3 includes a mounting box 31 housed within the extension tube 21, and an evacuation element 32 is disposed above the mounting box 31. The evacuation element 32 is a cone with a sharp top.

[0032] Multiple connecting rods 33 are evenly arranged on the outer circumference of the mounting box 31. The other end of the connecting rod 33 is connected to the inner side of the extension cylinder 21. The mounting box 31 is fixed in the middle of the extension cylinder 21 by the multiple connecting rods 33.

[0033] In this embodiment, the evacuation component 32 is a cone with a sharp top. The cone is installed directly above the mounting box 31, which is a cylinder with a diameter smaller than the bottom diameter of the cone. The mounting box 31 is fixed to the middle of the extension cylinder 21 by four connecting rods 33, thereby fixing the evacuation component 32 in the middle position of the extension cylinder 21. When rubber is fed into the mixing chamber body 1 through the feed hopper 2, the rubber falling from the feed hopper 2 falls directly onto the evacuation component 32. The sharp top of the evacuation component 32 can break the falling rubber, separating and evacuating it, thereby preventing the rubber from getting blocked during feeding and ensuring that the rubber enters the mixing chamber body smoothly, thus improving the feeding efficiency.

[0034] Preferably, the number of connecting rods 33 is 3 to 5. In this embodiment, there are 4.

[0035] Specifically, a motor 34 is installed inside the mounting box 31, and the output shaft of the motor 34 passes through the mounting box 31 and is connected to the bottom of the evacuation component 32.

[0036] The outer circumference of the cone has several evacuation grooves 35, which are evenly arranged around the cone.

[0037] In this embodiment, a motor 34 can be installed inside the mounting box 31. The top end of the output shaft of the motor 34 passes through the mounting box 31 and is connected to the bottom of the evacuation component 32. Thus, the evacuation component 32 can be driven to rotate by the motor 34, further crushing the falling rubber feed and causing the falling rubber feed to separate and evacuate.

[0038] Meanwhile, an evacuation groove 35 is opened on the outer circular surface of the evacuation component 32 of the cone. The number of evacuation grooves 35 can be set according to actual needs. When the evacuation component 32 rotates, the evacuation grooves 35 can improve the crushing effect, further improve the efficiency of crushing the falling rubber feed, and improve the feeding efficiency.

[0039] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
