Description

Technical Field

[0001] This utility model relates to the field of rubber extruder technology, and in particular to an automatic pin removal device for rubber extruders. Background Technology

[0002] Rubber extruders are crucial semi-finished extrusion molding equipment in tire production. They mainly consist of a motor, reducer, temperature control device, die head, screw, barrel, and pins. The pins are installed radially and equidistantly on the barrel of the extruder and extend into the barrel to work with the screw to form a continuous shear force on the rubber compound, thereby improving the plasticity of the rubber.

[0003] Existing technologies often have the following drawbacks: the pin arrangement needs to be frequently adjusted according to different rubber materials, processes, and semi-finished parts, and the screw needs to be replaced regularly. All of these require disassembling the pins of the extruder, which is a lot of work. The pin pullers provided by manufacturers are manually pulled out by using the inertia of a heavy object to strike the pull rod upwards. This is very physically demanding for the operators, and in some cases, such as when there is leakage, the pins cannot be pulled out at all.

[0004] Therefore, this utility model provides an automatic pin removal device for rubber extruders. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where manual removal of pins by using the inertia of a heavy object to strike the pull rod fails. Therefore, this invention proposes an automatic pin removal device for rubber extruders.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic pin removal device for a rubber extruder, comprising a motor reducer, a rotating mechanism, a moving mechanism, and a pin removal tool. The motor reducer drives the rotating mechanism to rotate. The moving mechanism is connected to the rotating mechanism in a transmission manner. The pin removal tool is installed at the end of the moving mechanism, and the end of the pin removal tool is provided with a bolt structure adapted to the internal thread of the pin body. A one-way anti-rotation cover is provided on the outside of the pin removal tool. The pin removal tool and the one-way anti-rotation cover cooperate to achieve one-way rotation.

[0007] Preferably, the moving mechanism includes a lead screw assembly connected to the rotating mechanism, and the nut end of the lead screw assembly is fixedly connected to the pin removal tool.

[0008] Preferably, the inner side of the moving mechanism is provided with a spring mechanism, one end of which is connected to the moving mechanism and the other end abuts against the one-way anti-rotation cover, for pressing the pin removal tool onto the pin body.

[0009] Preferably, the moving mechanism is equipped with an electromagnetic sensor and a magnetic ring that cooperates with the electromagnetic sensor, for sensing the position of the pin removal tool and controlling the start and stop of the motor reducer.

[0010] Preferably, the main body is further provided with a handle mechanism for gripping and moving the entire device to facilitate alignment with the pin body.

[0011] Preferably, the lead screw of the lead screw assembly is connected to the output shaft of the motor reducer via a coupling, and the nut end is slidably connected to the guide rail on the main body via a slider.

[0012] Preferably, the one-way anti-rotation cover is provided with a one-way bearing, and the pin removal tool passes through the one-way bearing and is connected to the rotating mechanism to realize the one-way rotation of the pin removal tool.

[0013] In summary:

[0014] By setting the above-mentioned structure, the operator only needs to press the start button to remove the pin during the process of removing the pin, which improves work efficiency and reduces the labor intensity of the operator. Compared with the prior art, this application improves work efficiency and reduces the labor intensity of the operator. Attached Figure Description

[0019] Reference Figure 1-3 As shown, this utility model provides a technical solution: an automatic pin removal device for a rubber extruder, including a motor reducer 1, a rotating mechanism 3, a moving mechanism 4, and a pin removal tool 8.

[0020] The following is a detailed explanation of its overall setup and function.

[0021] In this implementation scheme: the motor reducer 1 is used to drive the rotating mechanism 3 to rotate, the moving mechanism 4 is connected to the rotating mechanism 3 in a transmission manner, the pin removal tool 8 is installed at the end of the moving mechanism 4, and the end of the pin removal tool 8 is provided with a bolt structure that is adapted to the internal thread of the pin body 11. The outer side of the pin removal tool 8 is provided with a one-way anti-rotation cover 6, and the pin removal tool 8 and the one-way anti-rotation cover 6 cooperate to achieve one-way rotation.

[0022] Specifically, the moving mechanism 4 includes a lead screw assembly connected to the rotating mechanism 3, with the nut end of the lead screw assembly fixedly connected to the pin removal tool 8. A spring mechanism 5 is provided inside the moving mechanism 4, with one end connected to the moving mechanism 4 and the other end abutting against the one-way anti-rotation cover 6, used to press the pin removal tool 8 onto the pin body 11. An electromagnetic sensor 9 and a magnetic ring 7 cooperating with the electromagnetic sensor 9 are installed on the moving mechanism 4, used to sense the position of the pin removal tool 8 and control the start and stop of the motor reducer 1. A handle mechanism 2 is also provided on the main body 1, used to grip and move the entire device for easy alignment with the pin body 11. The lead screw of the lead screw assembly is connected to the output shaft of the motor reducer 1 via a coupling, and the nut end is slidably connected to the guide rail on the main body 1 via a slider. A one-way bearing is provided inside the one-way anti-rotation cover 6, through which the pin removal tool 8 passes and connects to the rotating mechanism 3, enabling unidirectional rotation of the pin removal tool 8.

[0023] Working principle: When the motor is started, it rotates clockwise, causing the rotating mechanism 3 to rotate clockwise. The moving mechanism 4 moves upward, causing the pin removal tool 8 to also move upward. When the pin removal tool 8 contacts the pin body 11, the spring presses it against the one-way stop cover 6. Simultaneously, the pin removal tool 8 rotates clockwise. The bolt of the pin removal tool 8 is connected to the internal thread of the pin body 11. When the upper electromagnetic sensor 9 senses the magnetic ring 7, the motor stops rotating clockwise and automatically starts rotating counterclockwise. During counterclockwise rotation, the moving mechanism 4 moves downward, and the pin removal tool 8 should rotate counterclockwise. However, because the pin removal tool 8 and the one-way anti-rotation cover 6 work together, the pin removal operation can only rotate clockwise and cannot rotate counterclockwise. When the motor rotates counterclockwise, the pin removal tool 8 does not rotate but only moves downwards, thus removing the pin from the extruder. When the electromagnetic sensor 9 senses the magnetic ring 7, the motor stops and the pin is removed. By setting the above structure, during the pin removal process, the operator only needs to press the start button to remove the pin, which improves work efficiency and reduces the labor intensity of the operator. Compared with the prior art, this application improves work efficiency and reduces the labor intensity of the operator.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
