Description

Technical Field

[0001] The utility model relates to the technical field of rubber cutting of synchronous belts, in particular to a rubber cutting device for raw rubber of sulfur-free and low-zinc synchronous belts. Background Art

[0002] The main materials of rubber synchronous belts are raw rubber, compounding agents, fiber materials and metal materials. Raw rubber is the basic material, compounding agents are auxiliary materials added to improve certain properties of rubber products, fiber materials (cotton, linen, wool and various artificial fibers, synthetic fibers) and metal materials (steel wire, copper wire) are used as skeleton materials of rubber products to enhance mechanical strength and limit product deformation.

[0003] In the process of raw material preparation, the ingredients must be weighed accurately according to the formula. In order to make the raw rubber and the compounding agent mix evenly with each other, some materials need to be processed, such as cutting the raw rubber and breaking it into small pieces for subsequent mixing. However, the existing rubber cutting equipment is large in size and occupies a large area, and the feeding process is inconvenient. In addition, the conventional roller shaft is driven by an external fixed motor. Due to the extrusion deformation during the rubber cutting process, the whole equipment shakes, which indirectly increases the wear of the shaft and increases the equipment cost. Therefore, we propose a rubber cutting equipment for sulfur-free and low-zinc synchronous belt raw rubber to solve the above problems. Utility Model Content

[0006] Furthermore, the supporting steel combination includes long horizontal steel, short horizontal steel, connecting vertical steel and a top plate.

The connecting vertical steel includes multiple ones, and its two ends are respectively fixedly connected to the long horizontal steel and the short horizontal steel. The top plate is welded to the top surface of the long horizontal steel as a whole, and the driving member is connected and fixed to the top plate.

[0007] Furthermore, two parallel heightening steels are fixed at the bottom of the base plate, and the two ends of the heightening steel are exposed on the base plate and welded and fixed to the vertical steels.

[0017] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0018] According to one embodiment of the present invention, Figure 1-Figure 3 Shown.

[0019] like Figure 1 As shown, for the overall structure, a rubber cutting device for raw rubber with sulfur-free and low-zinc synchronous belt 402 includes: a base 1, a rubber cutting box 2, a hob shaft 3 and a driving member 4. The top of the rubber cutting box 2 is hollowed out and fixedly connected to the base 1. The hob shaft 3 includes at least two and is rotatably connected to the two ends of the rubber cutting box 2. The shaft section of the hob shaft 3 exposed at one end of the rubber cutting box 2 is connected and rotated with the driving member 4, and the shaft section exposed at the other end of the rubber cutting box 2 is meshed and driven by a synchronous gear 7. The base 1 is also provided with a buffer 5 at the bottom corresponding to the driving member 4. The buffer member 5 includes a base plate 501, a spring 502, a vertical steel 503 and a supporting steel assembly 504. The bottom of the vertical steel 503 is vertically fixed on the base plate 501, and the top thereof is bolted to a limiting rod 505. The two ends of the spring 502 are respectively connected and fixed to the base plate 501 and the supporting steel assembly 504. The limiting rod 505 is used to limit the height of the bottom of the supporting steel assembly 504, and when the supporting steel assembly 504 is at the maximum limit height, the two sides of the top of the supporting steel assembly 504 overlap with the two ends of the base 1.

[0020] Through the above structure, the driving member 4 can drive the roller shaft 3 to rotate in the rubber cutting box 2 to cut and crush the raw rubber. The raw rubber feed can be directly fed in through the top of the opening of the rubber cutting box 2. During the rubber cutting process, in order to avoid the wear of the roller shaft 3 caused by the shaking of the equipment, a buffer member 5 is added at the bottom of the driving member 4. The driving member 4 and the spring 502 are connected through the supporting steel combination 504. When the spring 502 is compressed to the limit rod 505 and contacts the supporting steel combination 504, the two ends of the top of the supporting steel combination 504 can be placed on the top of the base 1 in an erected manner. The shaking of the equipment during the rubber cutting process is reduced by the expansion and contraction of the spring 502, which is simple and reliable.

[0021] like Figure 2 and Figure 3 As shown, specifically, the supporting steel combination 504 includes a long horizontal steel 5041, a short horizontal steel 5042, a connecting vertical steel 5043 and a top plate 5044. The short horizontal steel 5042 is located in the base 1 and the bottom surface is connected and fixed to the spring 502. The long horizontal steel 5041 is longer than the short horizontal steel 5042 and its two ends are correspondingly overlapped at the two ends of the bottom of the base 1. The connecting vertical steel 5043 includes a plurality of connecting vertical steels, and its two ends are respectively fixedly connected to the long horizontal steel 5041 and the short horizontal steel 5042. The top plate 5044 is welded to the top surface of the long horizontal steel 5041 as a whole, and the driving member 4 is connected and fixed to the top plate 5044.

[0022] Furthermore, two parallel heightening steels 5045 are fixed at the bottom of the base plate 501. Both ends of the heightening steel 5045 are exposed on the base plate 501 and are welded and fixed to the vertical steels 503. The vertical steels 503 include four ends corresponding to the two heightening steels 5045 respectively. The limiting rods 505 include two and are rotatably connected to the top ends of the two vertical steels 503 respectively. The top surfaces of both ends of the short horizontal steels 5042 are in contact with the limiting rods 505.

[0023] The overall supporting steel combination 504 is spliced ​​into an I-shaped structure with sufficient structural rigidity. The two ends of the top long horizontal steel 5041 are used to overlap the two ends of the bottom of the external base 1, and the two ends of the bottom short horizontal steel 5042 are used to correspond to the limit rod 505 for limit contact. The overall structure ensures sufficient supporting rigidity for the drive member 4, and its own welding structure is also relatively light, which is easy to install and position.

[0024] As for the selection of the driving member 4, there may be actually multiple types. In the present embodiment, the driving force required for the roller cutter shaft 3 is realized by means of a servo motor 401 in combination with a reducer 403. Specifically, the driving member 4 includes a servo motor 401, a timing belt 402 and a reducer 403. The servo motor 401 and the reducer 403 are both fixed to the top plate 5044 by bolts. One end of the reducer 403 is transmission-connected to the output end of the servo motor 401 through the timing belt 402, and the other end is connected and fixed to the shaft section of the roller cutter shaft 3 exposed to the rubber cutting box 2.

[0025] Similarly, for the connection of the two ends of the hob shafts 3 away from the driving member 4, the rubber cutting box 2 is also fixed with a gear box 6 at the end away from the driving member 4, and two mutually meshing synchronous gears 7 are rotatably connected in the gear box 6, and the hob shafts 3 are two and correspondingly coaxially connected to the synchronous gears 7. The two hob shafts 3 are arranged opposite to each other, and after the driving member 4 drives the hob shafts 3 to rotate, the hob blade on one of the hob shafts 3 is correspondingly embedded and engaged with the hob groove on the other hob shaft 3.

[0026] Through the above arrangement, after one of the hob shafts 3 is driven to rotate by the servo motor 401, the other hob shaft 3 can be relatively rotated through the synchronous gear 7 meshing at the other end, so that the hob blades and hob grooves on the two hob shafts 3 can cooperate with each other to achieve the cutting and crushing of the raw rubber material.

[0027] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
