Description

Technical Field

[0001] This utility model relates to the field of material processing equipment technology, and in particular to a fully automatic silicone rubber mixing machine. Background Technology

[0002] A rubber mixing mill mainly consists of rollers, a frame, an adjusting device, and a transmission device. The rubber compound is drawn into the gap between two counter-rotating rollers at different linear velocities under the action of friction. As the compound passes through this gap, it undergoes intense shearing and compression, causing the material temperature to rise and its plasticity to increase, thus achieving the purpose of rubber mixing. This process is used for plasticizing, mixing, tableting, and hot refining.

[0003] When silicone rubber is extruded and mixed in a rubber mixing mill, in order to ensure that the silicone rubber is evenly extruded and the quality of the mixture is guaranteed, the workers need to put the silicone rubber that has been extruded once back between the two extrusion rollers for mixing again. However, because the volume and weight of the silicone rubber mixed in a single batch are large, it is difficult for the workers to operate when turning it over, which greatly increases the workload. Secondly, the two extrusion rollers are constantly rotating when turning over, which poses a safety hazard to the workers. Summary of the Invention

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-3 The image shown is an embodiment provided by this utility model.

[0023] This utility model embodiment provides a fully automatic silicone rubber mixing machine, including: a first conveyor belt 10, a second conveyor belt 20, a first pressure roller 30, a second pressure roller 40, a third conveyor belt 50, and a winding roller 60, all of which are mounted on the frame of the rubber mixing machine.

[0024] Specifically, the winding roller 60 is rotatably mounted at the front end of the first conveyor belt 10. The winding roller 60 is mounted on the frame via a bearing seat and is perpendicular to the conveying direction of the first conveyor belt 10. The rear end of the first conveyor belt 10 is connected to the front end of the second conveyor belt 20, with a gap of ≤5mm between them to prevent the adhesive from falling off. The first pressure roller 30 is rotatably mounted above the rear end of the second conveyor belt 20, with a gap of ≤5mm between the first pressure roller 30 and the upper surface of the second conveyor belt 20, allowing the roller surface of the first pressure roller 30 to contact the adhesive earlier. The second pressure roller 40 is rotatably positioned on the side of the first pressure roller 30 near the front end of the second conveyor belt 20. The gap between the first pressure roller 30 and the second pressure roller 40 can be adjusted by a gap adjustment device to adapt to the processing of materials of different thicknesses. The front end of the third conveyor belt 50 is continuously positioned on the side of the second pressure roller 40 away from the first pressure roller 30. The rear end of the third conveyor belt 50 is located above and close to the rear end of the first conveyor belt 10. The vertical distance between the rear end of the third conveyor belt 50 and the first conveyor belt 10 can be set to 30-50cm to ensure that the material falls back smoothly.

[0025] The first conveyor belt 10 can transport the rubber compound to the second conveyor belt 20. The rubber compound typically includes silicone rubber materials of different mixing stages and shapes, such as rubber lumps and rolls. Rubber lumps refer to the rubber compound placed on the first conveyor belt 10 to begin mixing. Rolls refer to rubber lumps that have been extruded into sheets and then rolled into a cylindrical shape. The second conveyor belt 20 is used to receive the rubber compound (in the state of rubber lumps at this stage) and transport it to the first pressure roller 30. The first pressure roller 30 and the second pressure roller 40 are rotatably engaged to extrude the rubber compound into sheets, which are then sequentially pulled by the first pressure roller 30 and the second pressure roller 40 to the third conveyor belt 50. The third conveyor belt 50 is used to receive the sheets and transport them to their rear end, causing the sheets to gradually fall onto the first conveyor belt 10. The first conveyor belt 10 can transport the sheets in the opposite direction to the winding roller 60, which is used to rewind the sheets into rolls.

[0026] Furthermore, the first conveyor belt 10 includes two auxiliary conveyor belts 11 arranged side by side and capable of independent bidirectional operation. First sensor controllers 12 are symmetrically arranged on the outer sides of the two auxiliary conveyor belts 11, i.e., on both sides of the first conveyor belt 10. The first sensor controllers 12 can employ infrared photoelectric sensors to detect whether a roll of material is being conveyed through the middle of the first conveyor belt 10. They can also temporarily control the two auxiliary conveyor belts 11 to operate in the same direction at a differential speed or in opposite directions, changing the orientation of the conveyed roll. For example, when the roll of material passes laterally between the two first sensor controllers 12, the sensor signal... The signal is sent to the drive motors of the two auxiliary conveyor belts 11. By changing the speed of the two drive motors, a speed difference is created between the two auxiliary conveyor belts 11. This causes the end of the transverse material roll on the faster auxiliary conveyor belt 11 to gradually deflect forward, while the other end deflects relatively backward, achieving the effect of transforming transverse conveying into near-vertical conveying. Similarly, if the two auxiliary conveyor belts 11 are controlled to run in opposite directions, the forward-running auxiliary conveyor belt 11 will cause one end of the material roll to deflect forward, and the reverse-running auxiliary conveyor belt 11 will cause the material roll to deflect backward, thus achieving the effect of turning the material roll. It is understood that the control of the two auxiliary conveyor belts 11 by the first sensor controller 12 is only temporary and short-term. It can be set according to the time required for the material roll to be completely turned in actual production, such as controlling the two auxiliary conveyor belts 11 to run at different speeds for 5-8 seconds or in opposite directions for 3-5 seconds, so that normal conveying can be resumed after the material roll has been turned.

[0027] After adopting the aforementioned fully automatic silicone rubber mixing machine, the closed-loop conveying path of "first conveyor belt 10 -- second conveyor belt 20 -- first pressure roller 30 -- second pressure roller 40 -- third conveyor belt 50 -- first conveyor belt 10" automatically completes multiple extrusion mixing of silicone rubber without requiring manual refeeding of the rubber material into the gap between the pressure rollers. Compared with traditional rubber mixing machines, this completely avoids the risk of contact with the rotating pressure rollers during manual material turning, and eliminates the manual turning step, reducing the labor workload per mixing cycle. Simultaneously, the two bidirectional auxiliary conveyor belts 11 of the first conveyor belt 10, in conjunction with the first induction controller 12, can automatically adjust the orientation of the material roll, ensuring that the force direction is different each time the material roll enters the pressure rollers, resulting in more uniform mixing. Furthermore, the closed-loop conveying allows the mixing process to proceed continuously without stopping, greatly improving processing efficiency.

[0028] Specifically, one end of the second pressure roller 40 is connected to the drive motor via gears and a chain, and the other end of the second pressure roller 40 is connected to the end of the first pressure roller 30 via gear transmission. The rotation direction of the first pressure roller 30 is the same as the rotation direction of the second conveyor belt 20, and the rotation direction of the second pressure roller 40 is opposite to the rotation direction of the first pressure roller 30, forming a squeezing and shearing force on the rubber material. The rotation direction of the third conveyor belt 50 is the same as the rotation direction of the second pressure roller 40, and the rotation direction of the winding roller 60 is the same as the rotation direction of the third conveyor belt 50. If the second conveyor belt 20 rotates from left to right, the first pressure roller 30 rotates clockwise, the second pressure roller 40 rotates counterclockwise, the third conveyor belt 50 rotates from right to left, and the winding roller 60 rotates counterclockwise.

[0029] Furthermore, the first conveyor belt 10 is horizontally positioned with an installation height of 80-100cm, facilitating operation and placement of the rubber mass. The front end of the second conveyor belt 20 is lower than its rear end, with an inclination angle of 10-15°, allowing the rubber mass to gradually rise in height. The first pressure roller 30 is horizontally lower than the second pressure roller 40, with a height difference of 5-10cm, further lifting the extruded sheet upwards. The front end of the third conveyor belt 50 is lower than its rear end, with an inclination angle of 15-20°, ensuring the sheet is smoothly conveyed above the first conveyor belt 10. This stepped layout ensures smooth conveying of the rubber material between components, preventing accumulation or jamming. In addition, to accommodate different conveying speeds and avoid accumulation, support rods are hinged to the bottom sides of the third conveyor belt 50. Several slots are provided at intervals from top to bottom on the frame below the sides of the third conveyor belt 50. The lower ends of the support rods can be inserted into the slots to adjust the lifting height of the rear end of the third conveyor belt 50, thereby adjusting the time it takes for the material to fall from the third conveyor belt 50 onto the first conveyor belt 10.

[0030] Furthermore, the winding roller 60 includes a driving winding roller 61 and at least one driven winding roller 62. The number of driven winding rollers 62 is typically 1-2, and can be adjusted according to the thickness of the material roll. The driving winding roller 61 is located close to the upper surface of the first conveyor belt 10 to facilitate receiving the material sheet. The driving winding roller 61 can be connected to an independent drive motor via a coupling, actively driving the front end of the material sheet upwards and backwards. The driven winding roller 62 is arranged parallel above the driving winding roller 61 to limit the material roll and prevent it from falling over the driving winding roller 61. Furthermore, the angle α between the plane containing the axis of the driven winding roller 62 and the axis of the driving winding roller 61 and the upper surface of the first conveyor belt 10 is ≤90°, preferably 60-90°. When the angle α is 60°, the material sheet quickly rolls backwards, resulting in a tighter roll, suitable for thinner material sheets. When the angle α is 90°, the rolling speed of the material sheet slows down, suitable for slightly thicker material sheets.

[0031] Furthermore, a vulcanizing agent addition box 51 is provided above the third conveyor belt 50. The vulcanizing agent addition box 51 is close to the front end of the third conveyor belt 50 to ensure sufficient mixing distance between the vulcanizing agent and the material sheet. Several discharge holes with a diameter of 0.5-1mm are opened at the bottom of the box, through which the vulcanizing agent can be evenly dripped or applied to the surface of the material sheet. Specifically, a support frame 52 is mounted above the third conveyor belt 50. The support frame 52 is made of stainless steel and its two ends are mounted on the frame on both sides of the third conveyor belt 50. A telescopic cylinder 53 is vertically mounted on the support frame 52. The lower end of the telescopic cylinder 53 can be connected to the top of the vulcanizing agent addition box 51 through a flange to drive the vulcanizing agent addition box 51 to rise and fall, so as to adjust the spacing of the vulcanizing agent dripping onto the material sheet or directly applying it to the surface of the material sheet.

[0032] Furthermore, a second sensing controller 54 is provided on one side of the front end of the third conveyor belt 50. This controller can be an infrared diffuse reflection sensor, with its sensing height adapted to the thickness of the material sheet. The second sensing controller 54 is electrically connected to the telescopic cylinder 53. The second sensing controller 54 is used to detect whether a material sheet is being conveyed past the front end of the third conveyor belt 50 and to control the start and stop of the telescopic cylinder 53. When the second sensing controller 54 detects that a material sheet is being conveyed past the front end of the third conveyor belt 50, it immediately sends a signal or sends a signal at intervals of 1-2 seconds to the controller of the telescopic cylinder 53, activating the telescopic cylinder 53 to lower the addition box to a preset height and begin adding vulcanizing agent. When the vulcanizing agent has been added, if the preset continuous addition time has been reached, the telescopic cylinder 53 raises the addition box to its original position, stopping the addition and preventing waste or over-addition of vulcanizing agent.

[0033] Furthermore, a third sensing controller 55 is provided on one side of the rear end of the third conveyor belt 50. The third sensing controller 55 has the same structure as the second sensing controller 54. The third sensing controller 55 is used to detect whether a sheet is being conveyed past the rear end of the third conveyor belt 50 and to control the first conveyor belt 10 to move from its rear end towards its front end. When the third sensing controller 55 detects the end of a sheet passing by, it sends a signal to the drive motor of the first conveyor belt 10, causing the first conveyor belt 10 to switch from "conveying backwards to the second conveyor belt 20" to "conveying forwards to the winding roller 60," thus realizing the reverse conveying and winding of the sheet.

[0034] Furthermore, the sensing height of the first sensor controller 12 is greater than that of the second sensor controller 54, and the sensing height of the second sensor controller 54 is equal to that of the third sensor controller 55. Typically, the sensing height of the first sensor controller 12 is 5-8 cm, used for detecting the material roll; the sensing heights of the second and third sensor controllers are 1-5 cm, used for detecting the material sheet, to avoid interference between different sensing signals. When the first conveyor belt 10 conveys the material roll backward, the first sensor controller 12 detects the material roll passing by and sends a signal to control the operation of the two conveyor belts 11: if it is necessary to adjust the orientation of the material roll, it controls the two conveyor belts 11 to operate in the same direction at a differential speed or in opposite directions, thereby realizing automatic adjustment of the material roll orientation.

[0035] The silicone rubber mixing process of the fully automatic silicone rubber mixing machine provided in this embodiment is as follows: First, the silicone rubber compound is placed at the rear end of the first conveyor belt 10. The first conveyor belt 10 rotates backward (at a speed of 2 m / min) to transport the compound to the second conveyor belt 20. Then, the second conveyor belt 20 transports the compound between the first pressure roller 30 and the second pressure roller 40. The two pressure rollers rotate in opposite directions, squeezing the compound into a sheet of a preset thickness, and pulling it to the third conveyor belt 50 under the action of friction. The third conveyor belt 50 rotates forward. When the sheet passes the front end, it triggers the second induction controller 54. The telescopic cylinder 53 drives the vulcanizing agent addition box 51 to descend to a preset height, and the vulcanizing agent drips through the discharge hole. The material falls onto the sheet and is evenly distributed as it is conveyed. The sheet falls back to the rear end of the first conveyor belt 10 after passing the rear end of the third conveyor belt 50. The third sensor controller 55 detects the sheet's passage and controls the first conveyor belt 10 to switch to forward operation. The sheet is then conveyed forward on the first conveyor belt 10 to the winding roller 60. The driving winding roller 61 rotates, working with the driven winding roller 62 to wind the sheet into a roll. Then, the first conveyor belt 10 resumes forward operation, conveying the roll towards the second conveyor belt 20. When the first sensor controller 12 detects the roll, it controls the two conveyor belts 11 to operate at different speeds in the same direction or in opposite directions, adjusting the roll from a transverse to near-vertical position. The roll continues to be conveyed forward, achieving cyclic rubber mixing. If multiple mixing operations are required, the above process can be repeated until the silicone rubber reaches the preset plasticity requirement. The entire process requires virtually no manual intervention.
