Description

Technical Field

[0001] This utility model relates to the field of internal mixer technology, and in particular to a temperature control device for mixing and processing in an internal mixer. Background Technology

[0002] Internal mixers, as core equipment in the processing of polymer materials such as rubber and plastics, are widely used in industrial scenarios such as tire manufacturing, engineering plastic modification, and rubber seal production. Their core function is to achieve powerful shearing, extrusion, and mixing of materials through the synergistic action of the rotor shearing and the inner wall of the mixing chamber. In this process, temperature is a key parameter determining mixing efficiency and finished product quality: excessively high temperatures can easily lead to material scorching and premature reaction of crosslinking agents, resulting in deterioration of product performance; excessively low temperatures can lead to insufficient material flowability, uneven dispersion, and cause filler agglomeration or interfacial bonding defects. Therefore, precise temperature control is necessary.

[0003] In most existing equipment, a temperature sensor is fixedly installed at a certain point in the mixing tank to monitor the temperature inside the tank in real time. The traditional single-location or sparse distribution of sensors cannot fully reflect the temperature gradient in different axial and circumferential areas of the mixing chamber, which can easily create blind spots in local temperature monitoring and affect the overall temperature control accuracy. At the same time, if multiple temperature sensors are installed, the traditional fixed installation with bolts will result in poor installation and disassembly maintenance efficiency. It is difficult to quickly fix multiple temperature sensors, which affects the efficiency of the equipment and causes great inconvenience.

[0004] To address this issue, those skilled in the art have proposed a temperature control device for mixing and processing in an internal mixer to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1: As Figures 1 to 5 As shown: This utility model provides a temperature control device for mixing and processing in an internal mixer, including a structural component, including a structural component 101, a temperature detection component 102 disposed on the periphery of the structural component 101, a fixing component 103 disposed on one side of the temperature detection component 102, and an unlocking component 104 disposed on the outside of the structural component 101.

[0027] The structural component 101 includes a mixing tank 101a, a cover plate 101b rotatably disposed on the upper side of the mixing tank 101a, a support leg 101c disposed on the peripheral side of the mixing tank 101a, and a fixing sleeve 101d fixedly installed on the peripheral side of the mixing tank 101a.

[0028] The temperature detection component 102 includes a temperature sensor 102a that is slidably connected to one side of the fixed sleeve, a sensing contact 102b disposed at one end of the temperature sensor 102, and a temperature control box 102c that is fixedly installed on the upper side of the mixing tank 101a. Multiple temperature sensors 102a are provided and are evenly distributed on the peripheral side of the mixing tank 101a.

[0029] The fixing member 103 includes a post 103a fixedly installed at one end of the temperature sensor, a rod 103b fixedly installed at one end of the post, a slot 103c opened on the end side of the fixing sleeve 101d, a mounting groove 103d opened on the side wall of the rod 103b, a wedge 103e slidably disposed on one side of the mounting groove 103d, and a compression spring 103f fixedly installed on the inner side wall of the mounting groove 103d; one side of the wedge 103e is configured as a beveled part, and the other side is configured as a horizontal part;

[0030] The fixing member 103 also includes a through hole 103g opened on the peripheral side of the fixing sleeve 101d, and the wedge 103e extends into the through hole 103g and is slidably disposed therewith.

[0031] Preferably, eight temperature sensors 102a and eight fixing members 103 are provided, arranged in two rows and distributed at equal angles on the circumferential side of the mixing tank 101a. This achieves multi-layer coverage detection in both the axial and circumferential directions of the mixing tank, eliminating blind spots of traditional single-point monitoring and ensuring the comprehensiveness and real-time nature of temperature data acquisition.

[0032] Preferably, the fixing member 103 further includes a fixing plate 103h fixedly installed inside the through hole 103g and a top rod 103i slidably connected to the fixing plate 103h, one end of the top rod 103i being in contact with the wedge block 103e.

[0033] Preferably, the fixing member 103 further includes an arc-shaped protrusion 103j fixedly installed at the other end of the top rod 103i and a return spring 103k sleeved on the outer surface of the top rod 103i. The two ends of the return spring 103k are respectively connected to the side wall of the fixing plate 103h and the arc-shaped protrusion 103j.

[0034] Preferably, the unlocking component 104 further includes a mounting plate 104a fixedly fitted on the outside of the fixing sleeve 101d, an annular plate 104b slidably disposed on the outside of the fixing sleeve 101d, and a tension spring 104c, the two ends of the tension spring 104c being connected to the mounting plate 104a and the annular plate 104b respectively.

[0035] Preferably, the fixing member 103 further includes a plug block 103l fixedly installed at one end of the plug post 103a, the plug block 103l extending into the fixing sleeve 101d;

[0036] The unlocking component 104 also includes a main spring 104d disposed on the inner side wall of the fixed sleeve 101d. One end of the main spring 104d is installed on the inner side wall of the fixed sleeve 104d, and the other end is in contact with the end of the insert block 103l. The sensing contact 102b passes through the insert post 103a and the insert block 103l.

[0037] During installation, the insertion rod 103b is inserted into the slot 103c. During insertion, the inner wall of one side of the slot 103c first presses against the inclined surface of the wedge 103e, pressing the wedge 103e into the mounting groove 103d. When the insertion rod 103b slides to the through hole 103g, the wedge 103e in the mounting groove 103d is pushed outward by the rebound force of the compression spring 103f and extends into the through hole 103g. At this time, the side wall of the through hole 103g contacts and locks the horizontal surface of the wedge 103e, thus securing the insertion rod 103b. The locking mechanism allows for quick and easy installation of the temperature sensor 102a without the need for screwdrivers or other tools. Eight temperature sensors 102a and eight fixing pieces 103 are arranged in two rows, equidistantly distributed on the circumferential side of the mixing tank 101a. This arrangement of eight temperature sensors 102a in two rows provides multi-layered coverage detection in both the axial and circumferential directions of the mixing tank, eliminating blind spots in traditional single-point monitoring and ensuring comprehensive and real-time temperature data acquisition.

[0038] Preferably, when the temperature sensor 102 is installed, the arc-shaped surface of the arc-shaped protrusion 103j is located outside the fixed sleeve 104d, while the contact surface between the arc-shaped protrusion 103j and the push rod 103i is located inside the fixed sleeve 101d. Example 2: The return spring 103k can be used to reset the push rod 103i. When the arc-shaped protrusion 103j is pressed, the push rod 103i is squeezed inward, and the squeezing wedge 103e presses it back into the mounting groove 103d, releasing the locking of the insertion rod 103b. At this point, it can be pulled out for quick disassembly.

[0039] With the mounting plate 104a, annular plate 104b, and tension spring 104c, when the temperature sensor 102a needs to be quickly disassembled, the annular plate 104b can be pulled outward. When the annular plate 104b slides to the arc-shaped protrusion 103j, it can squeeze the arc-shaped protrusion 103j, causing the arc-shaped protrusion 103j and the push rod 103i to squeeze inward, thereby squeezing the wedge block 103e. At the same time, after pulling the annular plate 104b, the tension spring 104c can facilitate the auxiliary reset of the annular plate 104b for the next fixed installation.

[0040] By using the main spring 104d, when the temperature sensor 102a needs to be disassembled, after the push rod 103i presses the wedge 103e into the mounting groove 103d, the rebound force of the main spring 104d can assist in pushing out the insert 103l, thereby achieving the auxiliary ejection and disassembly of the temperature sensor 102a and improving the disassembly efficiency of the device.

[0041] As can be seen from the above, when the temperature sensor 102a needs to be quickly disassembled and repaired, after pulling the annular plate 104b outward, the annular plate 104b slides to the arc-shaped protrusion 103j and can squeeze the arc-shaped protrusion 103j, which in turn drives the arc-shaped protrusion 103j and the push rod 103i to squeeze inward, thereby squeezing the wedge block 103e and pressing the wedge block 103e into the mounting groove 103d. At this time, the insertion rod 103b can be pulled out directly for quick disassembly. At the same time, after the push rod 103i presses the wedge block 103e into the mounting groove 103d, the rebound force of the main spring 104d can assist in ejecting the insertion block 103l, thereby achieving the auxiliary ejection and disassembly of the temperature sensor 102a and improving the disassembly efficiency of the device.
