[0023] The rubber mixing apparatus of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1 to 3As shown, the rubber mixing apparatus provided in this embodiment of the present invention includes: a base 10, two rubber mixing rollers 20, a cutter assembly 30, and a drive assembly 40. The two rubber mixing rollers 20 are rotatably spaced on the base 10. The cutter assembly 30 is located below the rubber mixing rollers 20 and is movable along the axial direction of the rubber mixing rollers 20, and is used to cut the rubber on the surface of the rubber mixing rollers 20. The drive assembly 40 is located on the side of the base 10 and is connected to the two rubber mixing rollers 20 for transmission, so as to drive the two rubber mixing rollers 20 to rotate synchronously.

[0025] Specifically, the base 10 includes a base plate 11 and two support seats 12. The two support seats 12 are disposed opposite to each other on the base plate 11, and the two ends of the two rubber mixing rollers 20 are rotatably disposed on the two support seats 12, so that the two rubber mixing rollers 20 can rotate on the support seats 12, thereby completing the rubber mixing operation of the silicone colloid placed on the two rubber mixing rollers 20.

[0026] Reference Figure 1 and Figure 2 As shown, the cutter assembly 30 includes: a guide rod 31, a lead screw 32, a cutting blade 33, and a first motor 34. The guide rod 31 is mounted on the base 10; the lead screw 32 is rotatably mounted on the base 10 and is arranged parallel to the guide rod 31 in the axial direction; the cutting blade 33 is slidably mounted on the guide rod 31 and is threadedly connected to the lead screw 32; the first motor 34 is mounted on the base 10 and is connected to the lead screw 32 in a driving connection.

[0027] In this embodiment, when the first motor 34 drives the lead screw 32 to rotate, since the lead screw 32 is threadedly connected to the cutting blade 33, the lead screw 32 can drive the cutting blade 33 to move linearly along the length direction of the lead screw 32 when rotating, and is guided by the guide rod 31. The cutting blade 33 can abut against the rubber mixing roller 20, so that when the cutting blade 33 moves along the length direction of the lead screw 32, it can cut the silicone colloid on the circumferential surface of the rubber mixing roller 20. This ensures that the cutting action of the silicone colloid can be completed without manual operation during the rubber mixing process, improving the safety of manual operation during the rubber mixing process.

[0028] Reference Figure 2 and Figure 3 As shown, the cutting blade 33 includes a sliding blade holder 331 and a cutting blade 332. The sliding blade holder 331 is provided with a guide through hole and is slidably disposed on the guide rod 31, and is provided with an internal threaded hole and threadedly connected to the lead screw 32. The cutting blade 332 is disposed at the bottom of the sliding blade holder 331 and abuts against the rubber mixing roller 20 when cutting is required, so as to slide together with the sliding blade holder 331 on the guide rod 31. Furthermore, an elastic element 333 is provided between the cutting blade 332 and the sliding blade holder 331, and the two ends of the elastic element 333 abut against the cutting blade 332 and the sliding part, respectively.

[0029] In this embodiment, when the sliding cutter holder 331 is driven to move, the sliding cutter holder 331 is threadedly connected to the lead screw 32, so that the sliding cutter holder 331 can drive the cutter 332 to move on the guide rod 31, so that the cutter 332 cuts the silicone on the surface of the mixing roller 20. At the same time as the cutting is completed, the operator can complete the winding operation of the cut silicone, so that after winding, the silicone can be put back into the two mixing rollers 20 for mixing again. This process can be repeated to reduce the number of steps for the operator, and the safety of the operation process can be improved without manual cutting. It can be understood that by setting an elastic element 333 between the cutter 332 and the sliding cutter holder 331, the elastic element 333 can provide a certain buffer when the cutter 332 moves on the surface of the mixing roller 20, so as to avoid excessive friction between the cutter 332 and the mixing roller 20, and allow the cutter 332 to elastically press against the surface of the mixing roller 20.

[0030] The sliding cutter holder 331 has a sliding opening 3311 on its side along its length. The cutter 332 has a sliding stop 3325 that extends into the sliding opening 3311 and can slide. This allows the cutter 332 to be stopped and limited when it slides elastically within the sliding cutter holder 331. The sliding cutter holder 331 has a waist-shaped hole 3312 on one side along its width. The cutter 332 has a locking member 35 that passes through the waist-shaped hole 3312 and is connected to the cutter 332 at one end. The other end of the locking member 35 is located in the sliding cutter holder 331 and can be manually operated. The locking member 35 is threadedly connected to the cutter 332. Therefore, the locking member 35 can drive the cutter 332 to move up and down relative to the sliding cutter holder 331 to achieve the extension and retraction of the cutter 332. When it is necessary to cut silicone, the locking member 35 can be rotated to unlock the oblong hole 3312 from the cutter 332, so that the elastic force of the elastic member 333 can act on the cutter 332 and push the cutter 332 to fit against the surface of the rubber mixing roller 20 for silicone cutting. When it is not necessary to cut silicone, the locking member 35 can be operated to slide in the oblong hole 3312 to push the cutter 332 away from the rubber mixing roller 20, for example, retracting it into the sliding cutter holder 331. Rotating the locking member 35 reduces the distance between the locking member 35 and the cutter 332, allowing it to abut against the side wall where the oblong hole 331 is located for fixation. This locks the cutter 332 in the sliding cutter holder 331, avoiding interference when cutting is not needed and improving the safety of the production process. Furthermore, the locking element 35 and the cutter 332 can be connected by a nut, which is fixed on the cutter 332, increasing the stroke and adjustability of the threaded connection between the locking element 35 and the cutter 332, and preventing the locking element 35 and the cutter 332 from disengaging from each other.

[0031] Optionally, the first motor 34 can also be controlled independently to operate when cutting silicone is required and to stop operating when cutting is not required.

[0032] Furthermore, the cutter 332 includes: an embedding part 3321, two cutting parts 3322, and a glue-blocking part 3323. The embedding part 3321 is embedded in the sliding cutter holder 331 and can slide elastically in the vertical direction. The two cutting parts 3322 are spaced apart at both ends of the moving direction of the embedding part 3321. The glue-blocking part 3323 is disposed between the two cutting parts 3322 and has a gap with the two cutting parts 3322. Furthermore, the glue-blocking part 3323 has a glue-blocking arc surface 3324, and the orientation of the glue-blocking arc surface 3324 is opposite to the rotation direction of the rubber mixing roller 20.

[0033] In this embodiment, in order to reduce the operation during the cutting process, a glue-blocking part 3323 is provided between the two cutting parts 3322. After the cutting part 3322 cuts the silicone, the glue-blocking part 3323 can form a certain stopping effect on the silicone. When the mixing roller 20 continues to rotate, the silicone rotates with the mixing roller 20 and is stopped by the glue-blocking part 3323. This causes the silicone to be flipped away from the rotation direction of the mixing roller 20 by the glue-blocking part 3323. Then, the operator can roll up the silicone scooped up by the glue-blocking part 3323. This makes the operation of rolling up the silicone after it is cut simpler for the operator.

[0034] Preferably, the surface of the cutting blade 33 is coated with an anti-stick coating, wherein the anti-stick coating can be formed by coating such as silane compounds or fluorides, so that when the cutting blade 33 cuts the silicone colloid, the silicone can be prevented from sticking to the cutting blade 33, thereby ensuring that the operator can reduce the operation of removing silicone during the rubber mixing process.

[0035] Reference Figure 1 and Figure 4 As shown, the drive assembly 40 includes: a second motor 41, a drive gear 42, and a second gear. The second motor 41 is mounted on the base 10. The drive gear 42 is mounted on the motor shaft of the second motor 41 and meshes with the first gear, and is located at one end of one of the rubber mixing rollers 20. The second gear is located at one end of the other rubber mixing roller 20 and meshes with the first gear.

[0036] In this embodiment, when the second motor 41 drives the drive gear 42 to rotate, the second motor 41 can drive one of the rubber mixing rollers 20 to rotate and mix the rubber. At the same time, the drive gear 42 can drive the driven gear 43 to rotate, so that when the driven gear 43 rotates, it can drive the other rubber mixing roller 20 to rotate synchronously. By rotating the two rubber mixing rollers 20 synchronously, the silicone is repeatedly squeezed between the two rubber mixing rollers 20 to ensure that the added material can be evenly dispersed, and the overall degree of automation is higher.

[0037] The rubber mixing apparatus provided by this utility model can drive the rubber mixing roller 20 to mix rubber through the drive component 40, and at the same time, the cutter component 30 can move along the axial direction of the rubber mixing roller 20 so that the cutter component 30 can cut the silicone colloid on the surface of the rubber mixing roller 20, thereby eliminating the need for manual cutting of silicone, improving operational safety, and reducing manual intervention steps to better improve rubber mixing capacity.
