Description

Technical Field

[0001] This utility model relates to the field of tire processing technology, and in particular to a mixing equipment for tire tread rubber. Background Technology

[0002] The tread compound is the outermost layer of rubber in contact with the road surface and is imprinted with a tread pattern. It provides traction, cushions impacts and sway during driving, and prevents the tire cords from being cut or punctured. The main components of the tread compound include raw rubber such as natural rubber, styrene-butadiene rubber, and butadiene rubber, often with the addition of a large amount of carbon black to improve its physical and mechanical properties. Furthermore, the use of waste tire rubber powder in the tread compound can improve both the processing performance and the usability of the tread compound, while also effectively reducing raw material costs. The production process of the tread compound typically includes the following steps: raw material preparation, mixing, heating and melting, vulcanization, cooling and cutting, quality inspection, and packaging. During the mixing and heating / melting processes, mixing equipment is required to heat and stir the raw materials.

[0003] Regarding the aforementioned technologies, the inventors discovered that when adding raw materials to the mixing equipment, the raw materials are usually placed on a conveyor belt and then transported to the inner cavity of the mixing equipment. During the period when the raw materials on the conveyor belt pass through the feed inlet of the mixing equipment, some heat and dust flow out from the feed inlet, reducing the heat utilization rate and the cleanliness of the working environment. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a mixing equipment for tire tread rubber, which improves the utilization rate of heat and enhances the cleanliness of the working environment.

[0005] To solve the above technical problems, the present invention adopts a technical solution as follows: a mixing equipment for tire tread rubber is provided, including: a mixing equipment body and an inclined conveyor belt device, a conical storage box assembly is provided above the mixing equipment body, a telescopic pipe assembly is connected to the lower end discharge port of the conical storage box assembly, and a driving mechanism for driving the telescopic pipe assembly to expand and contract in the vertical direction.

[0006] A square feed pipe is connected to the top of the mixing equipment body. The lower end of the telescopic pipe assembly extends into the inner cavity of the square feed pipe. Two partitions are symmetrically hinged to the inner hole of the lower end of the telescopic pipe assembly. Hinged support rod assemblies are respectively connected to the lower surface of the partitions. The end of the hinged support rod assembly away from the partition is connected to the inner wall of the square feed pipe.

[0007] By adopting the above technical solution, during use, the raw material for the tread rubber is placed on an inclined conveyor belt device. The inclined conveyor belt device transports the raw material to the inner cavity of the conical storage box assembly. The raw material then flows downwards into the inner cavity of the telescopic pipe assembly. The operating drive mechanism causes the telescopic pipe assembly to contract, causing the two partitions to swing, forming a discharge cavity between the partitions. The raw material for the tread rubber falls from the discharge cavity and flows through the square feed pipe into the inner cavity of the mixing equipment body for further processing. After the raw materials in the conical storage box assembly are heated and stirred, and flow downwards, the operating drive mechanism extends the telescopic pipe assembly. The telescopic pipe assembly causes the baffles to swing at a certain angle, so that the opposing sides of the two baffles contact each other, thereby sealing the inner cavity of the square feed pipe. During the fall of the tread rubber raw materials, heat and fumes inside the square feed pipe are prevented from escaping. After the tread rubber raw materials are conveyed, the two baffles swing to seal the inner cavity of the square feed pipe, improving the heat utilization rate and enhancing the cleanliness of the working environment.

[0008] In a preferred embodiment, the present invention can be further configured as follows: the telescopic pipe assembly includes a square movable pipe and a bellows cover with a square cross-section. The upper end of the bellows cover is connected to the lower end outlet of the conical storage box assembly, and the lower end of the bellows cover is connected to the square movable pipe. The lower end of the square movable pipe extends into the square feed pipe and is slidably connected.

[0009] By adopting the above technical solution, the driving mechanism drives the square moving tube to move in the vertical direction, thereby driving the bellows cover to expand and contract.

[0010] In a preferred embodiment, the present invention can be further configured such that: the driving mechanism includes two symmetrically arranged telescopic rod assemblies, each telescopic rod assembly including an electric push rod, an upper fixed plate and a lower fixed plate connected to its two ends, the upper fixed plate being connected to the conical storage box assembly, and the lower fixed plate being connected to the outer surface of the square moving tube.

[0011] By adopting the above technical solution, the telescopic rod of the electric push rod extends and retracts, thereby driving the telescopic pipe assembly to expand and retract through the lower fixed plate.

[0012] In a preferred embodiment, the present invention can be further configured such that: the articulated support rod assembly includes a support rod, a first articulated seat and a second articulated seat hinged at both ends thereof, the first articulated seat being connected to a partition plate, and the second articulated seat being connected to the inner wall of a square feed tube.

[0013] By adopting the above technical solution, the telescopic pipe assembly rotates by driving two partitions through the support rod during the expansion and contraction process.

[0014] In a preferred embodiment, the present invention can be further configured such that: a plurality of opening slots are provided at intervals on one side of the partition, and shaft hinges are respectively connected in the opening slots, and the shaft hinges are connected to the inner wall of the square movable tube.

[0015] By adopting the above technical solution and using the shaft hinge, one side of the partition is hinged to the lower inner wall of the telescopic pipe assembly.

[0016] In a preferred embodiment, the present invention can be further configured such that the conical storage box assembly includes a conical storage box body and four rectangular array fixing rods, the upper end of which is connected to the conical storage box body and the lower end of which is connected to the mixing equipment body.

[0017] By adopting the above technical solution, the raw materials of the tread rubber are transported to the inner cavity of the conical storage box through an inclined conveyor belt device to achieve the purpose of storage. The conical storage box is indirectly and fixedly connected to the mixing equipment body by the use of fixing rods.

[0018] In summary, this utility model has at least one of the following beneficial technical effects:

[0019] The operating drive mechanism causes the telescopic pipe assembly to retract, which in turn causes the two partitions to swing, forming a discharge cavity between the partitions. The raw material for the tread rubber falls from the discharge cavity. During the fall of the raw material, heat and flue gas inside the square feed pipe are prevented from escaping. After the raw material for the tread rubber is delivered, the two partitions swing in opposite directions to seal the inner cavity of the square feed pipe, which improves the heat utilization rate and enhances the cleanliness of the working environment.

The drive mechanism drives the square moving pipe 41 to move vertically, thereby driving the bellows cover 42 to expand and contract.

[0034] The drive mechanism includes two symmetrically arranged telescopic rod assemblies 50. Each telescopic rod assembly 50 includes an electric push rod 51, an upper fixed plate 52 and a lower fixed plate 53 connected to its two ends. The upper fixed plate 52 is connected to the conical storage box assembly 30, and the lower fixed plate 53 is connected to the outer surface of the square moving tube 41. The telescopic rod of the electric push rod 51 extends and retracts, thereby driving the telescopic pipe assembly 40 to expand and retract through the lower fixed plate 53.

[0035] A square feed pipe 6 is connected to the top of the mixing equipment body 1. The lower end of the telescopic pipe assembly 40 extends into the inner cavity of the square feed pipe 6. Two partition plates 7 are symmetrically hinged to the inner hole of the lower end of the telescopic pipe assembly 40.
