Description

Technical Field

[0001] The utility model belongs to the technical field of rubber refining equipment, in particular to automatic rubber refining equipment. Background Art

[0002] In the field of rubber or plastic processing technology, there are many categories that need to be melted and blended by internal mixers and rubber mixers. Generally, products such as natural rubber, synthetic rubber, ethylene-vinyl acetate copolymer, etc. that are vulcanized and molded by vulcanizers and injection molded by new processes must be dispersed and mixed by internal mixers and rubber mixers, and then granulated or sheeted before entering injection or flat vulcanizer vulcanization molding. After mixing the raw material formula according to specific technical requirements by internal mixers, the raw materials and compound materials that were originally colloids, particles, and powders are fused and melted into agglomerates. However, the degree of dispersion between the various compound materials and the rubber (plastic) in the raw materials is still very low, and it has only reached a general degree of dispersion. In order to fully disperse the various components in the agglomerate and become flakes or granules that can enter the molding process, according to industry terminology, it must also be thinned through the rubber mixer (open mixer), and then made into films by the sheeting machine or made into rubber pellets by the granulator.

[0003] The existing rubber mixing machine usually includes a lifting device and a rubber mixing device; the lifting device is used to transport the rubber to the rubber mixing device, the rubber mixing device is used to mix the rubber into sheet rubber through two rollers, the sheet rubber is folded into stacked rubber through a rubber swing device, and the stacked rubber is generally transported manually. However, the rubber cannot meet the requirements after being mixed once by the rubber mixing device. When the rubber is mixed into sheet stacked by the rubber mixing device for the first time, it is manually transported to the lifting device, and the rubber is transported to the rubber mixing device again through the lifting device. When the rubber is mixed into sheet stacked rubber by the rubber mixing device again, it is still necessary to manually transport the rubber to the lifting device, and repeat this several times. In this way, relying on manual transportation of rubber, not only the labor intensity of personnel is large, but also the labor cost is high, and there will be a situation where the manual transportation speed cannot keep up with the rubber mixing speed of the rubber mixing device and the machine has to be stopped to wait for materials. After the shutdown of medium and large equipment, it needs to consume a certain amount of reactive power to restart, which invisibly increases the energy consumption and cost of the enterprise.

[0040] In one embodiment of the present utility model, referring to Figures 1-6 , an automatic rubber mixing device is provided, which includes a rubber mixing device 100, a rubber placing device 200, a lifting device 300, and a conveying device 400.

[0041] Among them, the rubber mixing device 100 is used to mix the rubber material into sheet-shaped rubber material.

[0042] Among them, the rubber placing device 200 is arranged in the rubber mixing device 100 and is used to fold the sheet-shaped rubber material into stacked rubber material.

[0043] Among them, the lifting device 300 is arranged beside the rubber mixing device 100 and is used to convey the rubber material to the rubber mixing device 100.

[0044] Among them, the conveying device 400 is arranged below the rubber placing device 200 and is used to carry and convey the stacked rubber material to convey the stacked rubber material to the lifting device 300 or output it.

[0045] Compared with the prior art, one or more of the above technical solutions in the automatic rubber mixing equipment provided by the embodiments of the present invention have at least one of the following technical effects:

[0046] Referring to Figures 1-3 , during operation, first place the lump-shaped rubber material in the lifting device 300. The lifting device 300 conveys the rubber material to the rubber mixing device 100. Then, the rubber mixing device 100 mixes the rubber material into sheet-shaped rubber material. Next, the rubber placing device 200 folds the sheet-shaped rubber material into stacked rubber material and stacks it on the conveying device 400. Finally, the conveying device 400 conveys the stacked rubber material to the lifting device 300 or outputs it. When multiple rubber mixing operations are required for the rubber material, the stacked rubber material after the first rubber mixing is conveyed back to the lifting device 300 through the conveying device 400. The lifting device 300 conveys this rubber material to the rubber mixing device 100 again. The rubber mixing device 100 remixes this rubber material into sheet-shaped rubber material. The rubber placing device 200 folds the sheet-shaped rubber material into stacked rubber material again and stacks it on the conveying device 400. Repeat the rubber mixing process multiple times in this way until the rubber material is output through the conveying device 400 after multiple rubber mixing operations. Therefore, when the automatic rubber mixing equipment of the present invention performs multiple rubber mixing operations, there is no need for manual handling of the rubber material, which not only reduces the labor intensity of personnel, but also reduces the labor cost. At the same time, it avoids the non-functional power consumption caused by the equipment stopping due to waiting for materials when the manual handling speed cannot keep up with the rubber mixing speed and then restarting the equipment.

[0047] In another embodiment of the present invention, referring to Figure 2 and Figure 3 , the rubber mixing device 100 includes a rubber mixing support 101. Two rollers 110 are rotatably arranged side by side on the rubber mixing support 101. Both ends of each roller 110 are rotatably connected to the rubber mixing support 101 through bearing seats (not shown in the figure). A rubber mixing gap 111 is formed between the two rollers 110. The rubber mixing support 101 is also provided with a first driving mechanism (not shown in the figure). The first driving mechanism is used to drive the two rollers 110 to rotate, so that the two rollers 110 mix the rubber material into sheet-shaped rubber material. Preferably, the rotation directions of the two rollers 110 are opposite, and the rotation directions of the two rollers 110 at the rubber mixing gap 111 are downward. Specifically, when the two rollers 110 rotate, the rubber material located between the two rollers 110 is strongly sheared and extruded by the peripheral walls of the two rollers 110 in the rubber mixing gap 111, causing the temperature of the rubber material to rise and the plasticity to increase. Thus, the rubber material is mixed into sheet-shaped rubber material and output from below the rubber mixing gap 111 to achieve the purpose of rubber mixing.

[0048] In some embodiments, the first driving mechanism includes a first motor and a transmission assembly; the first motor is drivingly connected to the two rollers 110 through the transmission assembly, so as to drive the two rollers 110 to rotate. Among them, the transmission assembly can be a transmission structure of transmission wheels and transmission belts or a transmission structure of a gearbox, etc. The above-mentioned transmission structures are all mature prior arts and will not be elaborated here. Alternatively, the first driving mechanism includes two reduction motors, the output shafts of the two reduction motors are respectively connected to the two rollers 110, and the two reduction motors are used to drive the two rollers 110 to rotate.

[0049] Further, referring to Figure 2 and Figure 3 , the rubber mixing device 100 further includes a feed hopper 120; a feed inlet 121 is provided at the lower end of the feed hopper 120, the feed hopper 120 is arranged on the rubber mixing bracket 101 and the feed inlet 121 is located above the rubber mixing gap 111, and the lifting device 300 conveys the rubber material into the feed hopper 120, and the feed hopper 120 guides the rubber material therein to be input into the rubber mixing gap 111 from the feed inlet 121 for accurate feeding.

[0050] Further, referring to Figure 3 , the rubber mixing bracket 101 is provided with a rubber scraping mechanism 130 on the side of the roller 110 away from the rubber mixing gap 111. The rubber scraping mechanism 130 includes a scraper 131 and a first driving unit 135. One end of the scraper 131 is a rubber scraping end 132, and a connecting shaft 133 is provided at the other end of the scraper 131. Both ends of the connecting shaft 133 are rotatably arranged on the rubber mixing bracket 101 through bearings. The first driving unit 135 is arranged on the rubber mixing bracket 101 and is connected to the connecting shaft 133 or the scraper 131, and is used to drive the rubber scraping end 132 to be close to or away from the peripheral wall of the roller 110. Specifically, when the first driving unit 135 drives the rubber scraping end 132 to be close to the peripheral wall, the rubber material adhered to the peripheral wall of the roller 110 will be scraped off when passing through the rubber scraping end 132, preventing the rubber material from adhering to the peripheral wall of the roller 110. When cleaning is required, the first driving unit 135 drives the rubber scraping end 132 to be away from the peripheral wall of the roller 110.

[0051] In a specific embodiment, referring to Figure 3 , the first driving unit 135 is a first cylinder, the cylinder body of the first cylinder is hinged to the rubber mixing bracket 101 through a first hinge seat 136, the telescopic rod of the first cylinder is hinged to one end of a first connecting rod 138 through a second hinge seat 137, and the other end of the first connecting rod 138 is fixedly connected to the connecting shaft 133 or the scraper 131. The telescopic movement of the telescopic rod of the first cylinder drives the rubber scraping end 132 to be close to or away from the peripheral wall of the roller 110, and the structure is simple. Alternatively, in other embodiments, the first driving unit 135 is a motor, the rotating shaft of the motor is fixedly connected to one end of the connecting shaft 133, and the connecting shaft 133 is driven to rotate by the motor, so as to drive the rubber scraping end 132 to be close to or away from the peripheral wall of the roller 110, and the structure is simple.

[0052] In another embodiment of the present utility model, referring to Figures 3-5 , the rubber dispensing device 200 includes a rubber dispensing bracket 210, a second driving mechanism 220, and a third driving mechanism 230. The rubber dispensing bracket 210 is fixedly installed on the rubber mixing bracket 101. Two rollers 240 are rotatably provided on the rubber dispensing bracket 210. The two rollers 240 are located below the rubber mixing gap 111. Preferably, the two rollers 240 and the two rollers 110 are both horizontally arranged, and the axes of the two rollers 240 are perpendicular to the axes of the two rollers 110. A rubber passing gap 241 is formed between the two rollers 240. The second driving mechanism 220 is arranged on the rubber dispensing bracket 210 for driving the two rollers 240 to reciprocate, so that the two rollers 240 reciprocally push the sheet-shaped rubber material to be folded into stacked rubber material. The third driving mechanism 230 is used for driving the two rollers 240 to rotate, so that the two rollers 240 rotate to guide the rubber material to pass through the rubber passing gap 241 and be conveyed downward. Preferably, the rotation directions of the two rollers 240 are opposite, and the rotation directions of the two rollers 240 at the rubber passing gap 241 are downward.

[0053] Specifically, during the process that the sheet-shaped rubber material continuously falls from below the rubber mixing gap 111, the second driving mechanism 220 drives the two rollers 240 to reciprocate, and the third driving mechanism 230 drives the two rollers 240 to rotate. The left roller 240 moves to the right and pushes the rubber material on the left side of the sheet-shaped rubber material to move to the right. At the same time, the left roller 240 rotates to guide (drive) the left rubber material to pass through the rubber passing gap 241 and be conveyed downward, so that the rubber material will not adhere to the peripheral wall of the roller 240. When the left roller 240 moves to the right and starts to move to the left, the right roller 240 moves to the left and pushes the rubber material on the right side of the sheet-shaped rubber material to move to the left. At the same time, the right roller 240 rotates to guide (drive) the right rubber material to pass through the rubber passing gap 241 and be conveyed downward, so that the rubber material will not adhere to the peripheral wall of the roller 240. This cycle is carried out to fold the sheet-shaped rubber material into stacked rubber material and stack it on the conveying device 400. Moreover, the two rollers 240 rotate to guide the rubber material to pass through the rubber passing gap 241 and be conveyed downward, that is, both of the two rollers 240 rotate in the rubber material feeding direction to guide (drive) the rubber material to pass through the rubber passing gap 241 and be conveyed downward. For rubber materials with relatively high viscosity, the rubber material will not adhere to the peripheral wall of the roller 240 either. The anti-adhesion effect is good, the applicable range is wide, and it has extremely high practicability.

[0054] Further, referring to Figure 4 and Figure 5 , an anti-adhesion coating is provided on the peripheral wall (surface) of the roller 240. The anti-adhesion coating can be materials such as Teflon, silicone rubber, ethylene, or silicone oil, which are not limited herein.

[0055] Further, referring to Figure 4 and Figure 5, the second driving mechanism 220 includes a linear guide 221, a rack 222, two moving seats 223 and two second driving units 224. The linear guide 221 is provided on the rubber dispensing bracket 210, and the rack 222 is provided on the rubber dispensing bracket 210 and arranged parallel to the linear guide 221. The two moving seats 223 are both slidably connected to the linear guide 221 through sliders 225, and the two rollers 240 are respectively rotatably provided on the two moving seats 223. The two second driving units 224 are respectively installed on the two moving seats 223, and a gear 226 is provided on the rotating shafts of the two second driving units 224, and the two gears 226 are both meshed with the rack 222. Specifically, the second driving unit 224 drives the gear 226 to rotate, and the gear 226 moves along the rack 222, thereby driving the moving seat 223 to move along the linear guide 221, and then driving the roller 240 to move. By respectively driving the two rollers 240 to move through the two second driving units 224, the two rollers 240 can move independently of each other; during cleaning, the second driving unit 224 drives the two rollers 240 to move away from each other to both sides, increasing the space between the two rollers 240, facilitating personnel to clean the rubber material, and facilitating cleaning and maintenance.

[0056] Preferably, the rack 222 is a helical rack 222, and the gear 226 is a helical gear 226. Through the cooperation mode of the helical gear 226 and the helical rack 222, the meshing process of the helix is longer than that of the straight tooth, that is, the contact ratio is larger, so that the load on the teeth is reduced, thereby prolonging the service life of the rack and the gear, and making the transmission stable, the operation stable, and the noise small.

[0057] In other embodiments, the second driving mechanism 220 may be a linear module, and the two rollers 240 are respectively rotatably provided on the two moving blocks of the linear module. The two moving blocks are driven by the linear module to move, thereby driving the two rollers 240 to move, and the structure is simple. Or, the second driving mechanism 220 includes two linear modules; the two rollers 240 are respectively rotatably provided on the two moving blocks of the two linear modules, and the two rollers 240 are respectively driven to move by the two linear modules.

[0058] Among them, the two second driving units 224 can both be second reduction motors, and the center of the gear 226 is fixed to the rotating shaft of the second reduction motor.

[0059] Further, referring to Figure 4 and Figure 5 , the third driving mechanism 230 includes two third driving units 231. The two third driving units 231 are respectively provided on the two moving seats 223 of the second driving mechanism 220, and the two third driving units 231 are respectively connected to the two rollers 240 and used to respectively drive the two rollers 240 to rotate. Among them, the two third driving units 231 can both be third reduction motors, and the output shaft of the third reduction motor is fixedly connected to one end of the roller 240, thereby driving the roller 240 to rotate, and the structure is simple.

[0060] Further, referring to Figure 5 , one end of the roller body 240 is rotatably arranged on the moving seat 223 through at least one first bearing seat 242, so that the roller body 240 is stably installed on the moving seat 223, and the structure is reliable.

[0061] Further, two linear guide rails 221 are symmetrically arranged on the rubber spreading bracket 210, and the moving seat 223 is slidably connected to the two linear guide rails 221 through a plurality of sliders 225, so that the moving seat 223 stably moves along the linear guide rails 221, and the structure is reliable.

[0062] In another embodiment of the present utility model, referring to Figure 1 and Figure 6 , the lifting device 300 includes a frame 310, a feeding hopper 320 and a fourth driving mechanism 330. The frame 310 is in a gate shape, and first tracks 340 and second tracks 350 are arranged on opposite sides of the frame 310 along its height direction.

Specifically, when it is necessary to convey the stacked rubber materials on the conveying mechanism 420 back to the feeding hopper 320 of the lifting device 300, the fifth driving unit 413 drives the conveying mechanism 420 to move towards the feeding hopper 320 of the lifting device 300, so that one end of the conveying mechanism 420 moves above the feeding hopper 320, and then the conveying mechanism 420 drives the stacked rubber materials to be accurately input into the feeding hopper 320. Then, the fifth driving unit 413 drives the conveying mechanism 420 to return to make way for the feeding hopper 320, avoiding affecting the movement of the feeding hopper 320. The structure is reliable. When it is necessary to convey the rubber materials after multiple rubber mixing operations on the conveying mechanism 420 to the discharging device 500, the fifth driving unit 413 drives the conveying mechanism 420 to move towards the discharging device 500, so that the other end of the conveying mechanism 420 approaches the discharging device 500. Then, the conveying mechanism 420 drives the stacked rubber materials to move onto the discharging device 500, and the discharging device 500 conveys the stacked rubber materials after rubber mixing to the next process, realizing automatic rubber mixing.
