Description

Technical Field

[0001] This utility model relates to the technical field of fabric forming machines, specifically a novel belt drum rear pressure roller device. Background Technology

[0002] Cord forming machines are specialized equipment used to form cord fabrics (such as rubber cord fabrics, fiber cord fabrics, etc.) into specific shapes and sizes. They are widely used in tire manufacturing, conveyor belt production, rubber product processing and other fields. The cord fabric is conveyed to the forming station by a feeding device, and sensors or mechanical positioning devices are used to ensure that the cord fabric is accurately aligned.

[0003] Regarding the above and existing related technologies: Traditional forming machines use a cylinder to directly drive a fixed nylon roller to roll the material behind the belt drum. The roller spacing and width are not adjustable. When producing new specifications of tires, it is necessary to replace and adjust the new roller, which can easily increase production costs and downtime. Therefore, a new belt drum rear roller device is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The novel belt drum rear pressure roller device of this utility model includes a bracket and a rotating rod. Two bearing seats are fixedly connected to the side wall of the bracket. The surface of the rotating rod is fixedly connected to the inner surface of the two bearing seats. A base is fixedly connected to the upper surface of the rotating rod. A lead screw is rotatably connected to the inner surface of the base. A movable seat is threadedly connected to the surface of the lead screw. Two main cylinders are fixedly connected to the upper surface of the movable seat. Two joints are fixedly connected to the side walls of the two main cylinders. A pressure plate is fixedly connected to the inner surface of the two joints. The rotating rod drives the base to move. When the base moves, the lead screw rotates, causing the lead screw to rotate on the inner surface of the base and the inner wall of the movable seat. The movable seat drives the main cylinders to move. After the pressure plate is in contact with the tire tread, the main cylinder is activated, causing the main cylinder to drive the joint to move. The joint drives the pressure plate to move, and the pressure plate rolls on the tire tread. By setting the entire device, the tire tread can be rolled and can also adapt to different tire tread specifications.

[0006] Preferably, two guide rods are fixedly connected to the surface of the base, and the surfaces of the two guide rods are slidably connected to the inner wall of the movable seat. When the movable seat moves, the movable seat slides on the surface of the guide rods, and the guide rods can guide and support the movable seat.

[0007] Preferably, a reducer is fixedly connected to the side wall of the lead screw, and a servo motor is fixedly connected to the bottom end of the reducer. The servo motor drives the reducer to move, and the reducer drives the lead screw to rotate. By setting the servo motor and the reducer, the lead screw can be easily driven.

[0008] Preferably, an auxiliary cylinder is fixedly connected to the surface of the bracket and the rotating rod. When the rotating rod needs to rotate, the auxiliary cylinder is driven to drive the rotating rod to move. By setting the auxiliary cylinder, the angle of the rotating rod can be adjusted.

[0009] Preferably, a slider is fixedly connected to the bottom end of the pressure plate, and a guide rail is fixedly connected to the upper surface of the movable seat near the slider. The inner wall of the slider and the surface of the guide rail are slidably connected, and the slider slides on the surface of the guide rail. By setting the slider and the guide rail, the position of the pressure plate can be restricted.

[0010] Preferably, the surfaces of the rotating rod and the base are provided with two reinforcing devices. Each reinforcing device includes a reinforcing rod located on the surfaces of the rotating rod and the base. A support column is fixedly connected to the side wall of the rotating rod near the reinforcing rod. The reinforcing rod is sleeved on the surface of the support column. A positioning pin is threadedly connected to the inner walls of the reinforcing rod and the support column. By rotating the positioning pin to the inner walls of the reinforcing rod and the support column, the base can be supported by the reinforcing rod, the support column, and the positioning pin.

[0011] Preferably, two limiting blocks are fixedly connected to the bottom end of the base near the reinforcing rod. Limiting grooves are provided on both sides of the reinforcing rod. The limiting blocks are inserted into the inner wall of the limiting grooves of the reinforcing rod. When the reinforcing rod moves, the reinforcing rod is sleeved on the surface of the limiting blocks through the limiting grooves. By setting the limiting blocks and limiting grooves, the position of the reinforcing rod can be restricted.

[0012] The advantages of this utility model are:

[0013] 1. When tire tread rolling is required, this utility model activates a servo motor to drive a reducer, which in turn drives a lead screw to rotate. The lead screw rotates on the inner surface of the base and the inner wall of the moving seat, causing the moving seat to move. As the moving seat moves, it slides on the surface of the guide rod. Then, an auxiliary cylinder is activated to drive a rotating rod to rotate. The rotating rod rotates a portion of the bearing housing structure. The rotating rod is fixed to the bracket via the bearing housing. The rotation of the rotating rod causes the base to rotate, which in turn drives the main cylinder on the moving seat to rotate. The rotation of the main cylinder activates the main cylinder, which in turn drives the connector to move. The connector then drives the pressure plate to move, pressing it against the tire tread. Simultaneously, the pressure plate rolls on the tire tread. The movement of the pressure plate causes the slider to slide, and the slider moves on the guide rail surface. By setting up the entire device, segmented pressure rolling of tire treads of different specifications can be achieved, improving compaction efficiency, reducing material waste, and enhancing rolling accuracy. It is flexibly applicable to rolling of different tire tread specifications.

[0014] 2. When using the base and rotating rod, the reinforcing rod is pushed to fit onto the surface of the support column. When the reinforcing rod moves, it fits onto the surface of the limiting block through the limiting groove. Then, the positioning pin is rotated to the inner wall of the reinforcing rod and the support column. When the base and rotating rod are under force, the force is transmitted to the reinforcing rod. By setting the entire device, the strength of the rotating rod and the base can be increased, thereby increasing the stability of the base and rotating rod during use. Attached Figure Description
