Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary processing equipment for rubber rods, specifically a rubber rod rolling device. Background Technology

[0002] Rubber rods are produced by extruding them through an extruder. After being cut to a fixed length, they need to be rolled into rounds and placed on a tray for subsequent processing. Because rubber rods are heated at high temperatures (60℃) and are heavy, manual labor can easily lead to fatigue. Therefore, a set of equipment needs to be designed to replace manual rolling.

[0003] Prior art, Chinese patent application number CN202121296227.7, discloses a rolling structure for an elastic sheet material. This structure uses a central rotating shaft and a positioning shaft below a forming shaft in a cylindrical structure. A positioning stop and a clamping plate compress the elastic sheet, and rotating the forming shaft rolls the elastic sheet into a circle. However, this method cannot achieve the requirement of a fixed-length, end-to-end circular connection for use with a rubber rod.

[0004] Therefore, this technical solution provides a rubber rod rolling device to meet the need for automatic rolling of rubber rods of a specific length. Utility Model Content

[0005] The present invention aims to provide a rubber rod rolling device to solve the problem that the existing technology cannot achieve automatic rolling of rubber rods of a specific length, thereby effectively avoiding the effects of high manual labor intensity and the impact of volatile substances on physical and mental health.

[0006] Technical solution: A rubber rod rolling device, including a worktable, wherein a head clamping mechanism, a tail clamping mechanism, an inner circle adjuster and a rotary table are provided on the worktable;

[0007] The head clamping mechanism is located in the radial groove of the rotary table. A lifting cylinder is installed on a fixed bracket on one side of the worktable. A tail clamping mechanism is set at the lower end of the lifting cylinder. The fixed bracket is also equipped with a sensor for detecting the presence or absence of the rubber rod. The operation of the head clamping mechanism and the tail clamping mechanism is realized through the control circuit.

[0008] The inner circle adjuster is located at the center of the rotary table and consists of an adjusting disc with several arc-shaped grooves and several telescopic rods. The central shaft of the inner circle adjuster is fixedly connected to a motor, which drives the adjusting disc to rotate.

[0009] Furthermore, the workbench is equipped with an adjustable guide plate to guide the rubber rod into the head clamping mechanism. A feeding roller is provided on the path from the adjustable guide plate to the head clamping mechanism, which helps to reduce the friction when the rubber rod moves, making the conveying of the rubber rod at high temperatures smoother.

[0010] Furthermore, both the head clamping mechanism and the tail clamping mechanism include clamping blocks located on both sides of the rubber rod. The clamping blocks are driven by cylinders to clamp and release, and their control is achieved through sensors and PLC circuits.

[0011] Furthermore, the reloading disc meshes with the power drive gear to realize the rotation of the rotary table. Preferably, the rotation speed of the rotary table is not less than the feeding speed of the rubber rod, so as to ensure that the rubber rod is not deformed by the feeding compression under the traction of the head clamping mechanism.

[0012] Preferably, a protective device is provided on the outside of the rotary table on the workbench. The protective device can adopt an arc-shaped cross-section design to achieve the technical effect of simultaneous protection on the outside and top, avoiding accidental release and injury during clamping.

[0013] Preferably, the telescopic rod of the inner circle adjuster is a sleeve rod structure, with a protrusion block provided on the telescopic rod. The protrusion block is located in the arc groove of the adjusting plate and is constrained by the arc groove. As the adjusting plate is rotated by the motor, it causes the protrusion block to slide in the arc groove of the adjusting plate, thereby changing the length of the telescopic rod.

[0014] Preferably, the bottom of the workbench is equipped with wheels with locking mechanisms.

[0015] Furthermore, the control circuit is a PLC controller, which includes a relay and its control circuit connected to achieve cylinder movement control.

[0016] Beneficial effects: This invention achieves neat end-to-end joining of rubber rods by replacing manual labor with clamping blocks, and automatically rolls the rods using residual heat for bonding. The use of a variable-diameter inner circle adjuster increases adaptability to rubber rods of different lengths. Combined with protective devices and adjustable guide plates, it ensures stability and controllability during the rolling process. After completion, the inner circle adjuster retracts to facilitate easy gripping. Compared to conventional manual rolling operations, this invention offers high efficiency and good rolling quality, effectively reduces labor intensity, integrates with automated production lines, and minimizes personal injury caused by hot rubber rods.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] A rubber rod rolling device includes a worktable 11, on which are mounted an adjustable guide plate 3, a head clamping block 4, a tail clamping block 5, an inner circle adjuster 6, a rotary table 7, a protective device 9, and a power drive gear 10. Four locking wheels are installed at the four corners of the bottom of the worktable 11 to enable movement and locking positioning of the device, facilitating transfer and integration with automated production lines. A rotary table 7 is located at the center of the worktable 11. The rotary table 7 has a geared shaft that meshes with the power drive gear 10. Through the action of a servo motor and a reducer, the rotary table 7 rotates at a uniform speed. Preferably, the rotation speed of the rotary table 7 should not be less than the feeding speed of the rubber rod 1 to ensure that the rubber rod 1 is not deformed due to the pressure of the feeding material, thus affecting quality.

[0023] A protective device 9 is provided on the outer ring of the rotary table 7. The protective device 9 has an arc-shaped cross-section to prevent the rubber rod 1 from being suddenly released during the rolling process and causing personal injury. It also plays a role in rounding and fixing the shape of the rubber rod 1 during rolling.

[0024] At the center of the rotary table 7, there is also an inner circle adjuster 6, which consists of an adjusting plate and telescopic rods. Several arc-shaped grooves are evenly arranged on the adjusting plate, corresponding to the installation of several telescopic rods. The telescopic rods adopt a sleeve structure, with protrusions on the outer rod of the sleeve located within the arc-shaped grooves on the adjusting plate. The bottoms of all telescopic rods are fixed in a uniformly distributed circular shape. A drive motor is connected to the bottom of the adjusting plate to rotate it. A blocking block is also provided at the end of the telescopic rod to increase the contact area. The rotation of the adjusting plate by the motor causes the position of the protrusions on the telescopic rods located within the arc-shaped grooves to change, resulting in a change in the length of the outer and inner sleeve rods of the telescopic rod.

[0025] A groove is provided radially on the rotary table 7. The head clamping mechanism 4 of the rubber rod 1 is located within the groove, and its position is determined according to the radius of the rolled rubber rod 8. A tail clamping mechanism 5 is provided above the head clamping mechanism 4. The tail clamping mechanism 5 is mounted on a vertical cylinder, which is mounted on a fixed bracket on one side of the worktable 11. The function of the vertical cylinder is to enable the tail clamping mechanism 5 to move up and down, facilitating the clamping and fixing of the tail of the rubber rod 1. A sensor for detecting the presence or absence of the rubber rod 1 is provided on the fixed bracket on one side of the worktable 11. This sensor can be a red photoelectric sensor or a proximity switch, etc. The operation of the vertical cylinder, the head clamping mechanism 4, and the tail clamping mechanism 5 is then controlled by a PLC or other control circuit. The head clamping mechanism 4 and the tail clamping mechanism 5 can be driven by a cylinder or a magnetic generator.

[0026] The adjustable guide plate 3 is a key component for guiding the rubber rod 1 into this device. The outlet of the adjustable guide plate 3 on the rotary table 7 must be aligned with the clamping block 4 at the head of the rubber rod. The adjustable guide plate 3 can be composed of two smooth guide plates. At the bottom of the channel of the adjustable guide plate 3, a feeding roller 2 is also provided to facilitate the easy sliding of the rubber rod 1.

[0027] The working principle of this utility model is as follows:

[0028] According to the predetermined working position, the worktable 11, equipped with four wheels, moves to the predetermined position and locks. A fixed-length rubber rod 1, extruded from the extruder, is guided by the adjustable guide plate 3 and the base feeding roller 2 to the head clamping block 4. A photoelectric sensor (proximity switch) on the worktable 11 has a certain detection range. When it detects that the head of the rubber rod 1 has entered the head clamping mechanism 4, the PLC control circuit quickly activates the cylinder to drive the clamping block, and the head clamping mechanism 4 clamps the head of the rubber rod 1. Subsequently, the power drive gear 10 starts, driving the rotary table 7 to rotate. The head clamping mechanism 4, located in the radial groove of the rotary table 7, rotates accordingly at a speed equal to the extruder feeding speed, thus achieving the best effect and preventing the rubber rod 1 from being deformed by the feeding pressure. Simultaneously, the inner circle adjuster 6 rotates its adjusting disc under the action of the motor. The protrusions located in the arc groove of the adjusting disc are constrained, causing the length of the telescopic rod of the inner circle adjuster 6 to change. The motor can be either a torque motor or a reversible motor, whose core characteristic is its ability to withstand the mechanical stress of load reversal without damage. Thus, as the head clamping mechanism 4 on the rotary table 7 makes circular motion, it completes the full circle.

[0029] When the tail of rubber rod 1 approaches the tail clamping mechanism 5, the sensor detects that there is no subsequent rubber rod 1, triggering the tail clamping mechanism 5 to act. A delayed action or similar method can be used to ensure the tail clamping mechanism 5 can grasp the tail of rubber rod 1. When the head clamping mechanism 4 moves to engage with the tail clamping mechanism 5, the residual heat of rubber rod 1 causes the head and tail to adhere, forming a rolled rubber rod 8. Finally, after completing the rolling and rounding actions, the inner circle adjuster 6 reverses and retracts the telescopic rod, releasing the head clamping mechanism 4 and the tail clamping mechanism 5, facilitating the grasping of the rolled rubber rod 8.
