Description

Technical Field

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

[0002] As a core processing equipment in the rubber industry, the open mixing mill primarily uses two counter-rotating rollers to shear, extrude, and mix raw materials. Its working principle is based on the shearing force generated by the speed difference between the rollers, which breaks down the rubber molecular chains and achieves plasticization, while simultaneously dispersing fillers and mixing vulcanizing agents. Traditional open mixing mills are widely used in the production of tires, seals, conveyor belts, and other products. Their simple structure and low maintenance costs make them important in small and medium-sized enterprises.

[0003] Traditional open mills for rubber processing use bolts to mechanically fix the scraper angle and pressure, which cannot be deflected. The fixed guide components easily cause uneven distribution of raw materials, directly affecting the mixing quality and energy efficiency. Furthermore, it is time-consuming and labor-intensive for operators to directly guide the scraper. Therefore, an open mill for rubber processing is provided to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the fixed guide components in the existing technology easily cause uneven distribution of raw materials, which directly affects the mixing quality and energy efficiency, and to propose an open mill for rubber processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rubber processing open mill includes a rubber open mill processing assembly. A guide adjustment component is installed on the rubber open mill processing assembly. Two raw material guides for guiding raw materials are threadedly connected to the guide adjustment component. Two scrapers are engaged at the contact portion between the bottom end of the raw material guide and the rubber open mill processing assembly. The raw material guide is also provided with a guide angle adjustment component to adjust the guide angle of the raw material guide.

[0006] Preferably, the rubber open mixing processing assembly includes a base, a drive chain, two sprockets, and two rubber processing rollers. A drive motor is mounted on the top of the base. The two sprockets are respectively connected to the output shaft of the drive motor and one end of the adjacent rubber processing roller. The two sprockets are connected by a drive chain. A gear is connected to the end of each rubber processing roller away from the sprocket, and the two gears mesh with each other.

[0007] Preferably, a housing is installed on both sides of the top of the base, and the two rubber processing rollers are rotatably connected to the inner wall of the housing, with a raw material tray engaged between the two housings.

[0008] Preferably, the guide adjustment component includes a servo motor and a positioning block. The servo motor and the positioning block are both fixed to the top of the adjacent housing. The output shaft of the servo motor is connected to a first screw via a coupling. The other end of the first screw is rotatably connected to the positioning block. The first screw is threadedly connected to two raw material guide components.

[0009] Preferably, the raw material guide includes a main screw and a lifting block. A limit rod is installed on the top of the lifting block, and a second screw is rotatably connected to the top of the lifting block. The second screw is threadedly connected to the main screw, and the limit rod is slidably connected to the main screw. A raw material scraper is rotatably connected to the bottom of the lifting block. The main screw is threadedly connected to the first screw, and the threads of the two main screws are in opposite directions.

[0010] Preferably, a raw material feed guide plate is installed on the top of the main screw to guide the raw material into the feed.

[0011] Preferably, both scrapers are engaged with the raw material scraper, and both scrapers are threaded with positioning screws, which penetrate the scrapers and are threadedly connected to the raw material scraper.

[0012] Preferably, a side support plate is installed at the bottom of the main screw, the guide angle adjustment component includes a third screw and a slider, the slider is slidably connected to the raw material scraper, a rotating shaft is installed on the slider, the third screw is rotatably connected to the rotating shaft, and the third screw passes through and is threadedly connected to the side support plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. This device integrates a guide adjustment component and a raw material guide component. The guide adjustment component uses a servo motor to drive a reverse threaded screw, enabling the two raw material guide components to adjust their spacing synchronously and precisely control the rubber processing width. The raw material guide component, through the cooperation of a lifting block and a limiting rod, can dynamically adjust the scraper pressure to ensure that the raw material is evenly distributed on the surface of the processing roller. The articulated scraper design, combined with the guide angle adjustment component, can flexibly adjust the deflection angle according to the characteristics of the raw material, effectively gathering or dispersing rubber particles. The setting of the feeding guide plate further simplifies the feeding process. The whole process is optimized from raw material feeding to finished product dropping onto the tray, taking into account both ease of operation and processing accuracy.

[0014] 2. The device adopts a double sprocket and gear linkage system, which can quickly adapt to the needs of different processing widths. The cooperation between the lifting block and the limit rod ensures the stability of the scraper pressure. The articulated scraper design combined with the sliding connection slider structure not only realizes the precise adjustment of the angle, but also avoids motion interference, enabling the equipment to flexibly cope with diverse processing scenarios.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] like Figure 1-7 As shown, this utility model provides a rubber processing open mill, including a rubber open mill processing component 1, a guide adjustment component 2 installed on the rubber open mill processing component 1, two raw material guide components 3 for guiding raw materials threadedly connected to the guide adjustment component 2, and two scrapers 5 engaged at the contact part between the bottom end of the raw material guide component 3 and the rubber open mill processing component 1. Among them, the raw material guide 3 is also provided with a guide angle adjustment component 4 for adjusting the guiding angle of the raw material guide 3.

[0020] In this embodiment, the rubber open mixing processing assembly 1 includes a base 16, a drive chain 12, two sprockets 13, and two rubber processing rollers 15. A drive motor 11 is installed on the top of the base 16. The two sprockets 13 are respectively connected to the output shaft of the drive motor 11 and one end of the adjacent rubber processing roller 15. The two sprockets 13 are connected by the drive chain 12. The ends of the two rubber processing rollers 15 away from the sprockets 13 are each connected to a gear 14. The two gears 14 mesh with each other. Housings 17 are installed on both sides of the top of the base 16. The two rubber processing rollers 15 are rotatably connected to the inner wall of the housing 17. A raw material tray 18 is engaged between the two housings 17.

[0021] The drive motor 11 drives the corresponding sprocket 13 to rotate, and the other sprocket 13 is linked by the drive chain 12. When the rubber processing roller 15 on the sprocket 13 rotates, the drive gear 14 drives the other gear 14 to rotate. At this time, both rubber processing rollers 15 rotate along the adjacent side. Rubber raw material granules are then poured in to refine the rubber raw material. The housing 17 and the base 16 are responsible for shielding the drive motor 11 and drive chain 12 and other drive components from exposure, reducing dust corrosion, and supporting the rotation of the rubber processing rollers 15. In this embodiment, the guide adjustment component 2 includes a servo motor 21 and a positioning block 23. The servo motor 21 and the positioning block 23 are both fixed to the top of the adjacent housing 17. The output shaft of the servo motor 21 is connected to a first screw 22 through a coupling. The other end of the first screw 22 is rotatably connected to the positioning block 23. The first screw 22 is threadedly connected to two raw material guide components 3.

[0022] The servo motor 21 drives the first screw 22 to rotate. Because the threads of the two main screws 31 are opposite, when the servo motor 21 is started, under the limit of the rubber processing roller 15, the two raw material guides 3 will move closer or further apart, so that the width of rubber processing can be adjusted as needed.

[0023] In this embodiment, the raw material guide 3 includes a main screw 31 and a lifting block 35. A limit rod 34 is installed on the top of the lifting block 35. A second screw 33 is rotatably connected to the top of the lifting block 35. The second screw 33 is threadedly connected to the main screw 31. The limit rod 34 is slidably connected to the main screw 31. A raw material scraper 36 is rotatably connected to the bottom of the lifting block 35. The main screw 31 is threadedly connected to the first screw 22, and the threads of the two main screws 31 are in opposite directions. A guide plate for guiding raw materials into the raw material feed is installed on the top of the main screw 31. 37. Both scrapers 5 are engaged with the raw material scraper 36. The two scrapers 5 are threaded with positioning screws 51. Both positioning screws 51 pass through the scrapers 5 and are threadedly connected to the raw material scraper 36. The bottom of the main screw 31 is equipped with a side support plate 32. The guide angle adjustment component 4 includes a third screw 41 and a slider 43. The slider 43 is slidably connected to the raw material scraper 36. A rotating shaft 42 is installed on the slider 43. The third screw 41 is rotatably connected to the rotating shaft 42. The third screw 41 passes through and is threadedly connected to the side support plate 32.

[0024] A lifting block 35 is provided at the bottom of the main screw 31. By rotating the second screw 33, the lifting block 35 and the raw material scraper 36 can be lowered under the limit of the limiting rod 34. This allows the pressure between the scraper 5 and the rubber processing roller 15 to be adjusted according to actual needs. The scraper 5 is fixed to the raw material scraper 36 by the positioning screw 51. When it needs to be removed, simply rotate and remove the positioning screw 51. The lifting block 35 and the raw material scraper 36 are hinged, and the raw material scraper can be adjusted by the guide angle adjustment component 4. The deflection angle of the material scraper 36 can be adjusted as needed when it is necessary to gather the material. The material feed guide plate 37 makes it easier for the operator to place the material between the two material guides 3. Rotating the third screw 41, supported by the side support plate 32, pushes or pulls the material scraper 36 through the rotating shaft 42 and the slider 43, allowing the material scraper 36 to rotate or deflect as needed. The slider 43 and the material scraper 36 are slidably connected to prevent the slider 43 from moving and limiting its movement. Furthermore, the rubber processing roller 15 has a built-in heating tube that can be used to heat and melt rubber raw material particles.

[0025] How to use and how to work this device: This device is based on the rubber refining and processing component 1, with the addition of a guide adjustment component 2 and a raw material guide component 3. It can assist the rubber raw material particles to enter, and can also cooperate with the scraper 5 and the guide angle adjustment component 4 to scrape the rubber raw material as needed. Finally, it assists the rubber raw material to be processed and refined into the final product, which falls into the raw material tray 18, and the operation is completed. Inside the rubber refining and processing assembly 1, the drive motor 11 drives the corresponding sprocket 13 to rotate, and the other sprocket 13 is linked by the drive chain 12. When the rubber processing roller 15 on the sprocket 13 rotates, the drive gear 14 drives the other gear 14 to rotate. At this time, both rubber processing rollers 15 rotate along the same side. When rubber raw material granules are poured in, the rubber raw material can be refined. The housing 17 and the base 16 are responsible for covering the drive motor 11 and drive chain 12 and other drive components to prevent them from being exposed, reducing dust corrosion while supporting the rotation of the rubber processing roller 15. Inside the guide adjustment component 2, the servo motor 21 drives the first screw 22 to rotate. Because the threads of the two main screws 31 are opposite, when the servo motor 21 starts, under the limit of the rubber processing roller 15, the two raw material guides 3 will move closer or further apart, so that the width of rubber processing can be adjusted as needed. Inside the raw material guide 3, a lifting block 35 is provided at the bottom of the main screw 31. By rotating the second screw 33, under the limit of the limiting rod 34, the lifting block 35 and the raw material scraper 36 can be driven to descend. This allows the pressure between the scraper 5 and the rubber processing roller 15 to be adjusted according to actual needs. The scraper 5 is fixed to the raw material scraper 36 by the positioning screw 51. When it needs to be removed, it is only necessary to rotate and remove the positioning screw 51. The lifting block 35 and the raw material scraper 36 are hinged. The deflection angle of the raw material scraper 36 can be adjusted by the guide angle adjustment component 4. When it is necessary to gather the raw material, the deflection angle of the raw material scraper 36 can be adjusted as needed. The raw material feed guide plate 37 makes it easier for the operator to put the raw material between the two raw material guides 3. Within the guide angle adjustment component 4, rotating the third screw 41 allows the raw material scraper 36 to be pushed or pulled back via the rotating shaft 42 and slider 43 under the support of the side support plate 32. This allows the raw material scraper 36 to rotate or deflect as needed. Furthermore, the slider 43 and the raw material scraper 36 are connected by a sliding connection to prevent the slider 43 from being limited in its movement.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
