Description

Technical Field

[0001] This utility model relates to the field of rubber track technology, and in particular to a rubber track preforming device. Background Technology

[0002] Rubber tracks are ring-shaped transmission belts made of high-strength rubber composite materials. They typically have embedded steel wire or fiber reinforcement layers to improve tensile strength, and their surfaces are designed with various patterns to enhance grip and drainage. This flexible transmission device effectively cushions impacts and reduces noise through the elasticity and wear resistance of rubber, while also possessing excellent anti-slip and wear-resistant capabilities. It is widely used in engineering machinery, agricultural equipment, snowmobiles, and other fields requiring heavy-duty transmission or special terrain traversal. Compared to traditional metal tracks, it offers significant advantages such as lighter weight, lower vibration, and less damage to the ground. However, existing rubber track pre-forming devices still suffer from problems such as easy misalignment during connection, failing to provide sufficient processing space for subsequent molding processes.

[0003] Therefore, it is essential to invent a rubber track preforming device. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a rubber track preforming device, which solves the problem that existing rubber track preforming devices are prone to misalignment during connection, failing to provide processing space for subsequent molding processes. A rubber track preforming device includes a positioning base, a rubber track surface, a screw drive structure, a rolling wheel, an auxiliary wheel, and a rubber base belt. The rubber track surface is laid on the surface of the positioning base, and both ends of the screw drive structure are fixedly installed on the outer side of the positioning base. The rolling wheel meshes with the screw drive structure. The auxiliary wheel is located on one side of the rolling wheel, and the rubber base belt wraps around the rolling wheel and the auxiliary wheel.

[0005] The positioning base includes a base, a positioning strip, a limiting strip, and a pattern placement groove. The positioning strip is fixedly installed at the middle position on the surface of the base, and the limiting strip is fixedly installed at both sides of the surface of the base. The pattern placement groove is disposed between the positioning strip and the limiting strip.

[0006] The compaction wheel includes a movable base, a support arm, a compaction roller, an extension arm, a tensioning push rod, and a connecting arm. The movable base is engaged with a screw drive structure, and the support arm is fixedly mounted on the movable base. The compaction roller is rotatably mounted on the support arm, and the extension arm is rotatably mounted on the outside of the compaction roller. The tensioning push rod is fixedly mounted on the rear end of the extension arm. The connecting arm is fixedly mounted on the rear end of the tensioning push rod and has an auxiliary wheel rotatably mounted on it.

[0007] The positioning base adopts a long, strip-shaped, track-like metal structure, and the pattern placement groove can accommodate the raised patterns on the surface of the rubber track surface. The positioning strip and the limiting strip can support the base of the rubber track surface and make the bottom surface of the rubber track surface base face upward. The rubber track surface above the pattern placement groove consists of two pieces, which can be supported by the pattern placement groove and contacted and bonded to the rubber base at the 12 o'clock and 6 o'clock positions, or the 9 o'clock and 3 o'clock positions. The bonding is not complete to facilitate subsequent pressure bonding work.

[0008] The compaction rollers inside the compaction wheel are made of a set of stainless steel metal wheels, and the compaction rollers can reciprocate in the horizontal direction of the positioning base by the support of the moving base and the support arm; the compaction rollers can move the auxiliary wheel away from or towards themselves by the extension arm, the tensioning push rod and the connecting arm; the outer sides of the compaction rollers and the auxiliary wheel are wrapped with a rubber base belt, and the compaction rollers and the auxiliary wheel can drive the rubber base belt to roll over the track surface.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The positioning base of this utility model provides stable support for the entire system. The positioning strip in the middle and the limiting strips on both sides together ensure the precise positioning of the rubber track surface and the rubber base belt. The specially designed pattern placement groove not only effectively protects the pattern structure of the rubber track surface from extrusion deformation during the preforming process, but also allows the bottom surface of the base to face upwards. With the synergistic action of the rolling wheel and the auxiliary wheel, it achieves local bonding at 12 and 6 points or 9 and 3 points. This asymmetrical bonding method not only ensures the initial fixing effect, but also provides space for subsequent pressure processing of the equipment, thereby significantly improving the accuracy, efficiency and quality stability of the preforming process.

[0011] 2. The rolling roller of this utility model achieves axial feeding motion through the precise meshing of the moving base and the screw drive structure. The rolling roller, whose support arm is fixedly installed, applies precise pressure to the rubber base belt during its movement. At the same time, the linkage mechanism composed of the extension arm, the tensioning push rod and the connecting arm adjusts the spacing of the auxiliary rollers in real time, so that the rubber base belt wrapped between the two rollers always maintains the optimal tension. This dynamic pressing mechanism not only ensures the tight bonding between the rubber base belt and the rubber track surface, but also effectively eliminates interlayer air bubbles. Combined with the reciprocating rolling action of the stainless steel rolling roller, it ultimately achieves high-precision composite of the rubber track surface pattern structure and the base belt material, providing an ideal semi-finished product state for the subsequent vulcanization process.

[0023] The positioning base 1 adopts a long strip-shaped track-like metal structure, and the pattern placement groove 14 can accommodate the raised pattern on the surface of the rubber track surface 2. The positioning strip 12 and the limiting strip 13 can support the base of the rubber track surface 2 and make the bottom surface of the base of the rubber track surface 2 face upward.
