Description

Technical Field

[0001] This utility model belongs to the field of conveying device technology, and more specifically, it relates to a polytetrafluoroethylene rod conveying device. Background Technology

[0002] Polytetrafluoroethylene (PTFE) rods are widely used in chemical, mechanical, and electronic fields due to their excellent chemical stability, high temperature resistance, and low coefficient of friction.

[0003] In existing technologies, common bar conveying devices mostly use flat belts or roller structures, but they are not well adapted to polytetrafluoroethylene (PTFE) bars. The bars are prone to deviating from the preset path during the conveying process, requiring frequent manual correction. This not only increases labor intensity but may also cause surface damage to the bars due to deviation and collision. Traditional conveying devices have fixed channel widths, making it difficult to adapt to bars of different diameters. When changing specifications, it is necessary to adjust or replace the equipment, which lacks flexibility. Therefore, there is an urgent need to design a conveying device specifically for the characteristics of PTFE bars, which can achieve automatic centering and convenient width adjustment to improve conveying efficiency and product protection performance. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a polytetrafluoroethylene rod conveying device, which is achieved by the following specific technical means:

[0005] A polytetrafluoroethylene (PTFE) rod conveying device includes a base, on both sides of the upper end of the base, mounting plates are slidably mounted, and several brackets are fixedly mounted at equal intervals along the length of each mounting plate. Each bracket is fixedly mounted with a mounting frame, and each mounting frame is inclined. A rotating roller is rotatably mounted on each mounting frame, and a synchronous pulley is fixedly mounted on the upper shaft end of each rotating roller. A synchronous belt is sleeved between adjacent synchronous pulleys. The rotating rollers on two mounting plates form a V-shaped rod conveying channel. A reducer for driving the rotating roller is mounted at one end of each mounting plate, and a rubber ring with a diamond pattern is sleeved on the outer surface of each rotating roller.

[0006] Furthermore, each of the mounting plates is fixedly mounted with a support rod, and each of the reducers is fixedly mounted on the support rod. The output shaft of the reducer is fixedly connected to the upper shaft end of one of the rotating rollers.

[0007] Furthermore, each of the synchronous belts is fitted with a protective shell, which is fixedly connected to the mounting bracket.

[0008] Furthermore, a dovetail block is fixedly installed at the bottom of each mounting plate, and dovetail grooves are provided on both sides of the upper surface of the base, with the two dovetail grooves arranged along the width direction of the base.

[0009] Furthermore, the two dovetail blocks are slidably installed in the dovetail grooves, and a threaded rod is rotatably installed in each dovetail groove.

[0010] Furthermore, each of the threaded rods passes through the dovetail block and is threadedly connected to the dovetail block, and a handwheel is fixedly installed on each of the threaded rods.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this PTFE rod conveying device, each roller is fitted with a rubber ring with a diamond pattern on its outer surface. The diamond pattern can significantly increase the friction between the roller and the PTFE rod. The V-shaped conveying channel formed by the two rollers can automatically center the rod after it is placed in, preventing the rod from deviating from the path during the conveying process. No manual correction is required, and the rod is prevented from being scratched due to collision with the device components. All rollers on the same mounting plate are driven by a "synchronous pulley + synchronous belt", and the individual rollers are driven by a reducer to drive the whole to rotate synchronously and at the same speed, avoiding rod conveying deviation and jamming due to differences in roller speed. At the same time, the V-shaped conveying channel formed by the two rollers can provide bidirectional limit for the rod, further ensuring that the rod is conveyed along the length of the mounting plate.

[0013] Second, the PTFE rod conveying device can flexibly adjust the width of the V-shaped conveying channel through the adjustment structure of "handwheel-threaded rod-dovetail block-dovetail groove": the operator only needs to turn the handwheel, and the threaded engagement between the threaded rod and the dovetail block will drive the mounting plates on both sides to move horizontally along the width direction of the base, thereby changing the width of the V-shaped channel formed by the rollers on both sides. This structure can adapt to the conveying needs of PTFE rods of different diameters without changing the equipment, thus improving the applicability of the device. Attached Figure Description

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a polytetrafluoroethylene (PTFE) rod conveying device, including a base 1, with mounting plates 2 slidably installed on both sides of the upper end of the base 1. Several brackets 3 are fixedly installed at equal intervals along the length of each mounting plate 2. Each bracket 3 is fixedly installed with a mounting frame 4. Each mounting frame 4 is inclined. Each mounting frame 4 is rotatably installed with a rotating roller 5. Each rotating roller 5 has a rubber ring on its outer surface, and the surface of the rubber ring has diamond-shaped patterns to increase the friction between the rotating roller 5 and the rod, and avoid slippage caused by the smoothness of the PTFE material.

[0026] Each roller 5 has a synchronous wheel 51 fixedly installed on its upper shaft end, and a synchronous belt 6 is sleeved between adjacent synchronous wheels 51. The rollers 5 on the two mounting plates 2 form a V-shaped bar conveying channel. Each mounting plate 2 has a reducer 7 installed at one end to drive the roller 5 to rotate.

[0027] Each mounting plate 2 is fixedly mounted with a support rod 11, and each reducer 7 is fixedly mounted on the support rod 11. The output shaft of the reducer 7 is fixedly connected to the shaft end of one of the rollers 5. When a single roller 5 rotates, it drives all rollers 5 on the same mounting plate 2 to rotate synchronously and at the same speed through the transmission of the synchronous pulley 51 and the synchronous belt 6.

[0028] The outer side of the synchronous belt 6 is covered with a protective shell 12, which is fixedly connected to the mounting bracket 4 to prevent debris and other objects from entering the transmission area and ensure stable operation of the transmission.

[0029] Each mounting plate 2 has a dovetail block 21 fixedly installed at its bottom end. Dovetail grooves 13 are provided on both sides of the upper surface of the base 1. The two dovetail grooves 13 are set along the width direction of the base 1. The tail structure restricts the mounting plate 2 to only move in the width direction to avoid displacement.

[0030] Two dovetail blocks 21 are slidably installed in dovetail grooves 13. Each dovetail groove 13 is rotatably installed with a threaded rod 9. Each threaded rod 9 passes through the dovetail block 21 and is threadedly connected to the dovetail block 21. Each threaded rod 9 is fixedly installed with a handwheel 91. The rotational motion of the threaded rod 9 is converted into the linear motion of the dovetail block 21, which in turn drives the two mounting plates 2 on both sides to move closer or further apart along the width direction of the base 1. This allows for adjustment of the width of the V-shaped bar conveying channel, improving the versatility of the device.

[0031] The working principle of this embodiment:

[0032] Step 1: The reducer 7 on the mounting plate 2 is fixed to the support rod 11. Its output shaft is directly fixedly connected to the upper shaft end of one of the rollers 5 on the same mounting plate 2. After the reducer 7 starts, the output torque drives the connected roller 5 to rotate. Each roller 5 has a synchronous pulley 51 installed on its upper shaft end, and all synchronous pulleys 51 on the same mounting plate 2 are driven by a synchronous belt 6. When a single roller 5 rotates, the synchronous pulley 51 and the synchronous belt 6 drive all rollers 5 on the same mounting plate 2 to rotate synchronously and at the same speed. After the rollers 5 rotate synchronously, they drive the polytetrafluoroethylene (PTFE) through friction. The polytetrafluoroethylene (PTFE) rod moves along the conveying channel. Each roller 5 has a rubber ring on its outer surface, and the surface of the rubber ring has a diamond pattern (to increase the friction between the roller 5 and the rod and avoid slippage caused by the smoothness of the PTFE material). The PTFE rod is placed into the V-shaped channel formed by the two rollers 5. The rod is in close contact with the rubber ring of the two rollers 5. The synchronously rotating rollers 5 generate a driving force on the rod along the conveying direction (the length direction of the mounting plate 2) through the friction between the rubber ring and the rod, which drives the rod to be conveyed smoothly forward along the V-shaped channel until the specified conveying stroke is completed.

[0033] Step 2: When the width of the conveying channel needs to be adjusted, the operator turns the handwheel 91 on the base 1. The handwheel 91 drives the threaded rod 9 in the dovetail groove 13 to rotate synchronously. Since the threaded rod 9 is threadedly connected to the dovetail block 21 at the bottom of the mounting plate 2, and the dovetail block 21 is slidably fitted in the dovetail groove 13 set along the width of the base by 1 degree (the dovetail structure restricts the mounting plate 2 to only move in the width direction to avoid offset), the rotational motion of the threaded rod 9 is converted into the linear motion of the dovetail block 21, which in turn drives the two mounting plates 2 to move closer or further away from each other along the width direction of the base 1, thereby enabling the adjustment of the width of the V-shaped bar conveying channel and improving the versatility of the device.

[0034] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
