Technical Field

[0001] This utility model relates to the field of open mill technology, specifically an open mill for rubber processing. Background Technology

[0002] Throughout the development of the rubber industry, the production of rubber products is inseparable from the uniform mixing and plasticizing of raw rubber and compounding agents. As the key equipment for realizing this core process, the technological evolution of the open mill has always been closely linked to the upgrading needs of the rubber industry.

[0003] In CN2808854U, a multi-stage plasticizing open mill apparatus is provided. However, during the use of this apparatus, due to the open design of the rubber mixing position, the rubber powder generated by rubber extrusion during the mixing process is easily dispersed into the surrounding environment, which can affect the health of workers. In addition, dust in the air can also enter the rubber, affecting the quality of the rubber. Therefore, an open mill for rubber processing is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a rubber processing open mill to solve the problem mentioned in the background art that, during the use of the device, due to the open design of the rubber mixing position, the rubber powder produced by rubber extrusion during the mixing process is easily scattered into the surrounding environment, which affects the health of workers, and the dust in the air can also enter the rubber, affecting the quality of the rubber.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rubber processing open mill, comprising a device body, two grooves on the upper surface of the device body, two sliders sliding inside each groove, protective shells fixedly connected to the upper surfaces of adjacent sliders, observation windows fixedly connected to the surface of each protective shell, sleeve rods fixedly connected to the lower surface of each protective shell, a sealing groove on the right side of one protective shell, and a sealing block fixedly connected to the left side of the other protective shell, the outer surface of the sealing block contacting the inner wall of the sealing groove, a first motor fixedly connected to the right side of the device body, and a bidirectional threaded rod fixedly connected to the output end of the first motor via a coupling, the outer surfaces of both ends of the bidirectional threaded rod being respectively connected to the internal threads of the two sleeve rods, and the internal threads of the two sleeve rods being adapted to the threads of the outer surfaces of both ends of the bidirectional threaded rod.

[0006] Preferably, a collection box is fixedly connected to the right side of the device body, and a storage box is provided inside the collection box.

[0007] Preferably, a filter plate is provided inside the collection box, and a protective plate is fixedly connected to the upper surface of the collection box.

[0008] Preferably, a fan is fixedly connected to the upper surface of the collection box, and the output end of the fan is fixedly connected to the front of the collection box.

[0009] Preferably, a connecting box is fixedly connected to the right side of the device body, and the right side of the connecting box is fixedly connected to the input end of the fan.

[0010] Preferably, a guide plate is fixedly connected to the lower surface of the device body, and a discharge pipe is fixedly connected to one end of the guide plate.

[0011] Preferably, a second motor is fixedly connected to the right side of the device body, and the output end of the second motor is fixedly connected to a transmission rod via a coupling.

[0012] Preferably, a hinge is fixedly connected to the outer surface of the transmission rod, and the outer surface of the hinge is in contact with the inner wall of the discharge pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This rubber processing open mill, by creating a groove on the upper surface of the main body and fixing the slider to the protective shell, allows the protective shell to slide stably along the groove. Simultaneously, a first motor drives a bidirectional threaded rod to rotate. Through the threaded transmission between the bidirectional threaded rod and the sleeve rod on the lower surface of the protective shell, the two protective shells move synchronously towards the center, allowing the sealing block to be precisely inserted into the sealing groove. This achieves a tight connection between the two protective shells, effectively sealing the processing area inside the main body of the machine. This prevents rubber dust and impurities from spilling out during the open milling process, improves the cleanliness of the working environment and reduces potential health risks to workers. Furthermore, it prevents external dust and impurities from entering the rubber in the machine and affecting product quality.

[0014] This rubber processing open mill uses a guide plate fixedly connected to the lower surface of the main body to guide the rubber scraps that fall during the open milling process, allowing the scraps to slide into the discharge pipe. This achieves directional collection and guidance of the scraps, preventing them from accumulating at the bottom of the main body. A second motor located on the right side of the main body drives a transmission rod and hinge plate to contact the inner wall of the discharge pipe and the guide plate, forcibly discharging the rubber scraps that have slid into the discharge pipe. This prevents the scraps from clogging the discharge pipe and achieves efficient discharge and recycling of the scraps. Attached Figure Description

[0017] Please see Figure 1-4 This utility model provides a technical solution: a rubber processing open mill, including a device body 1. Two grooves 6 are formed on the upper surface of the device body 1. Two sliders 5 slide inside each groove 6. Protective shells 9 are fixedly connected to the upper surfaces of adjacent sliders 5. The grooves 6 limit the position of the sliders 5, allowing them to slide left and right under the limiting effect of the grooves 6. The limiting effect of the grooves 6 further limits the position of the fixed protective shells 9. An observation window 7 is fixedly connected to the surface of each protective shell 9. The observation window 7 allows the worker to easily observe the rubber being processed inside the device body 1. The worker can adjust the running speed of the device body 1 in a timely manner according to the state of rubber refining.

[0018] A sleeve rod 19 is fixedly connected to the lower surface of the protective shell 9. A sealing groove 20 is opened on the right side of one protective shell 9, and a sealing block 8 is fixedly connected to the left side of the other protective shell 9. The outer surface of the sealing block 8 is in contact with the inner wall of the sealing groove 20. Through the tight contact between the sealing block 8 and the sealing groove 20, the device body 1 is sealed, effectively isolating the processed rubber from the outside world and preventing external dust and impurities from falling into the rubber and affecting its quality. At the same time, it prevents rubber dust from being emitted during processing and spreading into the surrounding air, thus protecting the health of workers in the surrounding environment. The device body 1 has a sound effect. A first motor 11 is fixedly connected to the right side of the device body 1. The output end of the first motor 11 is fixedly connected to a bidirectional threaded rod 10 through a coupling. The first motor 11 drives the bidirectional threaded rod 10 to rotate. The outer surfaces of both ends of the bidirectional threaded rod 10 are respectively connected to the internal threads of two sleeve rods 19, and the internal threads of the two sleeve rods 19 are respectively adapted to the threads of the outer surfaces of both ends of the bidirectional threaded rod 10. The thread transmission between the bidirectional threaded rod 10 and the two sleeve rods 19 enables the sleeve rods 19 to drive the protective shell 9 to move to the sides or the middle of the device body 1.

[0019] The device body 1 has a collection box 13 fixedly connected to its right side. The collection box 13 has a storage box 14 inside, which serves to store the rubber dust and impurities that enter the collection box 13.

[0020] The collection box 13 is equipped with a filter plate 15 inside, and a protective plate 18 is fixedly connected to the upper surface of the collection box 13. The filter plate 15 is used to filter the gas entering the collection box 13.

[0021] The upper surface of the collection box 13 is fixedly connected to a fan 17, and the output end of the fan 17 is fixedly connected to the front of the collection box 13. The fan 17 generates negative pressure in the processing area of ​​the device body 1, so that impurities inside the device body 1 are discharged from the device body 1.

[0022] The device body 1 has a connection box 16 fixedly connected to its right side. The right side of the connection box 16 is fixedly connected to the input end of the fan 17. The connection box 16 is used to collect the rubber powder generated by the device body 1 during the processing.

[0023] The device body 1 has a guide plate 12 fixedly connected to its lower surface, and a discharge pipe 2 fixedly connected to one end of the guide plate 12. The discharge pipe 2 collects the residue that falls off the device body 1 during the rubber processing.

[0024] The device body 1 has a second motor 21 fixedly connected to its right side. The output end of the second motor 21 is fixedly connected to a transmission rod 4 via a coupling. The second motor 21 drives the transmission rod 4 to rotate.

[0025] Among them, the outer surface of the transmission rod 4 is fixedly connected with the hinge 3, and the outer surface of the hinge 3 is in contact with the inner wall of the discharge pipe 2. Through the scraping action between the hinge 3 and the inner wall of the discharge pipe 2, the material that slides into the discharge pipe 2 through the guide plate 12 is discharged.

[0026] The motor is existing technology and will not be discussed in detail here. The components that match the motor include connecting wires, power supply, and microcontroller, which are also existing structures and will not be discussed in detail here.

[0027] Working Principle: In operation, the rubber to be refined is first placed inside the device body 1 using external tools and with the assistance of workers. Then, the first motor 11 is started, driving the bidirectional threaded rod 10 to rotate. This causes the two sleeve rods 19 to engage with the outer surface of the bidirectional threaded rod 10 via threaded transmission, moving the two protective shells 9 towards the center. The protective shells 9 and the slider 5 move towards the center under the limiting action of the sliding groove 6 until the sealing block 8 is inserted into the sealing groove 20, creating a tight connection between the two protective shells 9. This seals the interior of the device body 1, preventing the generation of rubber dust from the material inside. The rubber powder and dust generated inside the device body 1 are drawn into the surrounding environment, causing pollution and affecting the health of nearby workers. At the same time, it effectively prevents impurities from the surrounding environment from entering the rubber and affecting the quality of the rubber being processed. Then, the blower 17 is turned on. Using the blower 17 and the connecting box 16, a negative pressure is generated inside the device body 1, which pushes the rubber powder and dust impurities generated inside the device body 1 into the collection box 13. The gas containing dust is filtered by the filter plate 15 and discharged from the device through the protective plate 18. The filtered dust and impurities are collected into the storage box 14, and the rubber dust is collected through the storage box 14.

[0028] Then, the main body 1 of the device is started to break down the rubber. The rubber being broken down inside the main body 1 is observed through the observation window 7 so that the device can be adjusted in time. During the breaking down process, some rubber fragments fall into the inside of the guide plate 12. At this time, the second motor 21 is started. The second motor 21 drives the transmission rod 4 to rotate, which in turn drives the hinge 3 to rotate. The hinge 3 scrapes against the inner wall of the discharge pipe 2 and the guide plate 12, causing the rubber fragments to move towards one end of the discharge pipe 2 and the guide plate 12. Finally, the fragments are discharged from the device through the discharge pipe 2, achieving efficient collection of rubber fragments, preventing rubber fragments from accumulating at the bottom of the main body 1, increasing the difficulty of later cleaning, increasing the labor intensity of the workers, and facilitating the reuse of rubber fragments.
