Description

Technical Field

[0001] The utility model relates to the technical field of V-belt production, in particular to a combined feeding mechanism of a V-belt rubber coating machine. Background Art

[0002] With the continuous advancement of global industrialization and the rapid development of the machinery and equipment manufacturing industry, the demand for V-belts (also known as V-belts) is also growing continuously. The V-belt consists of a belt body and a canvas wrapped around the belt body, wherein the belt body consists of a top rubber, a wire core and a bottom rubber. The production process of the V-belt is a complex process involving multiple steps and links. Only through the steps of fine material preparation, rubber refining, preforming, cloth wrapping, vulcanization and other steps can a V-belt product that meets the standard requirements be produced. In the prior art, when manufacturing a V-belt, it is necessary to first compound the wire rope and the top rubber to form a wire rubber, then use a coating machine to coat the adhesive, and then coat the bottom rubber in the coating machine to form a belt embryo (then cut, wrap, and vulcanize to obtain the product). This secondary coating process not only affects production efficiency, but also is not conducive to cost control.

[0003] Due to the continuous growth of market demand, the original production capacity can no longer meet the requirements, and technological upgrades are needed to improve production efficiency. On the other hand, with the intensification of competition, downstream companies are more sensitive to product prices than before, which requires V-belt manufacturers to control production costs and reduce product prices. Therefore, if the coating can be achieved in one go on the coating machine, the production efficiency of the V-belt will be improved, and the production cost can be reduced. Summary of the invention

Its specific structure enables it to feed base glue and adhesive glue at the same time, and press the base glue and adhesive glue to form a composite glue during the feeding process, so that the V-belt production process only requires one gluing process. Compared with the traditional two-time gluing process, it can improve production efficiency and reduce manufacturing costs.

[0005] The technical solution of the utility model is as follows:

[0006] The combined feeding mechanism of the V-belt gluing machine comprises a bottom glue rack and a frame arranged in sequence along the feeding direction; the bottom glue rack is provided with a bottom glue roller device for installing the bottom glue roll, and correspondingly, the bottom glue rack or the side of the frame is provided with an auxiliary guide roller; the frame is provided with an adhesive discharging device on a side close to the bottom glue rack; the adhesive discharging device comprises a base column, and the base column is correspondingly provided with a discharging shaft that can be driven by a discharging driving element, and a bottom fabric recovery shaft that can be driven by a bottom fabric collection driving element; the bottom fabric recovery shaft is located on the discharging shaft , and the base fabric recovery shaft is located above the auxiliary guide roller; on the frame, at the front side of the adhesive discharge device, a correction and conduction device is provided; the correction and conduction device includes a gantry through which the adhesive can pass, and a conduction roller, a glue pressing mechanism and a correction guide roller arranged on the gantry; the conduction roller can be driven by a conduction power device; the glue pressing mechanism includes a glue pressing cylinder and a glue pressing plate, and the glue pressing plate is fixedly connected to the piston rod of the glue pressing cylinder; the correction guide rollers are arranged in pairs, and the two correction guide rollers are respectively arranged on both sides of the entrance of the gantry.

[0007] Compared with the prior art, the utility model adds an adhesive discharging device to the frame of the adhesive coating machine, and utilizes the cooperation of the discharging shaft on the adhesive discharging device and the base fabric recovery shaft to add the adhesive bonding process into the adhesive coating process, so that the base fabric and the adhesive can be fed at the same time, and in the feeding process, the adhesive is pressed onto the base fabric by a glue pressing plate to form a composite glue, so that the strip blank can be manufactured only by one glue coating. Compared with the traditional secondary glue coating process, the production efficiency is high and the manufacturing cost is lower.

[0008] Furthermore, in the aforementioned joint feeding mechanism of the V-belt glue coating machine, casters are provided in groups at the bottom of the bottom glue frame. Still further, the casters are casters with brakes. This structure can realize the movement and fixation of the bottom glue frame, more conveniently transport the bottom glue to the glue coating station, and has low manufacturing cost and is easy to implement.

[0009] Furthermore, in the aforementioned combined feeding mechanism of the V-belt gluing machine, a brake block is also provided at the bottom of the bottom glue frame, the brake block is provided at the lower end of the adjusting screw, the adjusting screw is connected to the bottom glue frame through a spiral pair, and an adjusting handle is provided at the upper end of the adjusting screw. Thus, when in use, the position of the brake block can be adjusted by adjusting the handle to press it against the ground, increase the friction between the bottom glue frame and the ground, further fix the bottom glue frame, make it more stable during the feeding process, and improve reliability.

[0010] Furthermore, in the aforementioned combined feeding mechanism of the V-belt gluing machine, the auxiliary guide roller is arranged on the frame. The auxiliary guide roller is arranged on the frame, which is more conducive to simplifying the structure of the bottom glue frame and making it lighter when moving.

[0011] Furthermore, in the aforementioned combined feeding mechanism of the V-belt gluing machine, the unloading drive element may be a motor. Still further, the unloading drive element is a torque-adjustable motor, which is connected to a torque controller.
