Description

Technical Field

[0001] The utility model relates to the technical field of rubber compacting equipment, in particular to a compacting structure for solid tire rubber raw materials. Background Art

[0002] Solid tires are generally divided into two types: bonded and non-bonded. The former refers to tires with rubber vulcanized directly on the rim, and the latter refers to tires fixed on the rim after vulcanization. For the latter, the connection between the rim and the tire during the assembly process is generally pre-wrapped with a layer of rubber material, mostly in a ring-shaped structure, with the rubber and plastic material wrapped around the inner and outer edges of the rim to further improve the shock resistance and stability of the tire.

[0003] However, in view of the different thicknesses along the rim itself, the opening diameters of each sealing rubber ring are required to be different. In actual use, the rubber ring opening often does not fit the rim edge well. Therefore, we propose a compaction structure for solid tire rubber raw materials. Utility Model Content

DETAILED DESCRIPTION

[0019] 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.

[0020] According to one embodiment of the present invention, Figure 1-Figure 3 Shown.

[0021] As for the overall structure, a compacting structure for solid tire rubber raw materials includes: a control console 1, the top surface of the control console 1 is flat and fixed with a symmetrical feeding track 2, a bearing platform 3 for supporting rubber raw materials is set on the feeding track 2, and a compacting component 4 is also set on both sides of the bearing platform 3 on the top surface of the control console 1, and the compacting component 4 includes an arched platform 401, a driving member 402 and a carrier plate 404, and the top surface of the carrier plate 404 is slidably connected to the top surface of the arched platform 401 through a telescopic rod 405, and the center of the top surface is aligned with the driving member 402. The movable member 402 is connected and fixed, and the bottom surface of the carrier plate 404 is servo-corresponding to the bearing platform 3. A pressing plate 406 for compacting the rubber raw material is fixed at the center of the bottom surface. The driving member 402 is used to drive the carrier plate 404 to servo-move with the bearing platform 3 axially. The top surface of the bearing platform 3 is a plane and a frustum 5 is raised at the center of the plane. A surrounding fixing ring 6 is fixed to the outer periphery of the side surface of the frustum 5. The fixing ring 6 is used to embed the rubber raw material and position it. The center of the pressing plate 406 is hollow and can pass through the top surface of the frustum 5 to contact the rubber raw material.

[0022] In the actual compaction process, the choice of the driving member 402 may include multiple options, such as common hydraulic pressure, air pressure, or ball screw, etc., which can realize the lifting and lowering operation of the pressing plate 406 in the height direction. In this embodiment, the driving member 402 is a servo cylinder 403, and its model is se32x25-s standard single-rod cylinder. The telescopic rod 405 includes at least two and is symmetrically fixed at both ends of the top surface of the arched platform 401. The output end of the servo cylinder 403 is connected and fixed to the center of the top surface of the carrier plate 404. Furthermore, the feed track 2 can be combined with an external ball screw module, and the center of the front of the carrier 3 is provided with a threaded hole 11 corresponding to the external ball screw module. The control console 1 is embedded with a control circuit and multiple control buttons 12 are integrated on the front. The servo cylinder 403 is electrically connected to the internal control circuit of the control console 1.

[0023] According to the above structure record, the control circuit in the control console 1 can communicate with the external ball screw module and the servo cylinder 403. The operator can pre-insert and fix the rubber raw material to be compacted through the fixing ring 6, and then the servo output of the ball screw module drives the carrier table 3 to slide along the feed track 2 to the bottom of the corresponding station of the compacting component 4, and then the servo cylinder 403 outputs to drive the carrier plate 404 to move downward. The back of the carrier plate 404 realizes relative sliding with the arched table 401 through four telescopic rods 405. The four telescopic rods 405 are located at the four corners of the back of the carrier plate 404. The pressing process ensures that it is horizontal and does not shake. After continuous pressing, the pressing plate 406 presses the rubber raw material on the fixing ring 6 outside the truncated table 5. The opening of the rubber raw material can be relatively tightly closed after being squeezed, thereby ensuring the subsequent tight sealing of the inner or outer ring of the wheel hub.

[0024] In order to further improve the stability of the compaction process of the pressing plate 406, the present application also vertically fixes a plurality of guide rods 7 on the top surface of the supporting platform 3 and the outer periphery of the truncated table 5. The plurality of guide rods 7 are arranged equidistantly in a circle around the center of the truncated table 5. Each of the guide rods 7 passes through the carrier plate 404 and the pressing plate 406. Each of the guide rods 7 is spaced apart from the rubber raw material and the spacing is not less than 5 cm.

[0025] Furthermore, a plurality of buffer columns are provided on the top surface of the cone 5, including at least one main buffer column 8 and at least three secondary buffer columns 9. The inner diameter of the main buffer column 8 is larger than that of the secondary buffer column 9. Each of the buffer columns is slidably connected to the top surface of the cone 5 and is elastically reset by a built-in spring. Each of the buffer columns is exposed on the top surface of the cone 5 and the maximum exposed shaft section length does not exceed 3 cm.

[0026] During the compaction process of the pressing plate 406, the present application further provides evenly distributed guide rods 7 on the outer side of the corresponding truncated table 5, and the pressing plate 406 slides and limits with it during the descent process. Similarly, for the top surface of the truncated table 5, the pressing process of the pressing plate 406 is buffered and decelerated by the embedded main buffer column 8 and the secondary buffer column 9 to avoid excessive downward pressure and wear and cracking caused by acute hard contact between the rubber raw material and the embedded fixing ring 6. As for the overall equipment, the present application further fixes vertical panels 10 on both sides of the top surface of the console 1, and the panels 10 are used to seal the compaction assembly 4, which is safe and reliable.

[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.
