Description

Technical Field

[0001] This invention belongs to the field of Teflon tape transportation technology, specifically referring to a Teflon tape transportation and guiding device. Background Technology

[0002] Teflon tape is widely used in packaging, thermoplastic molding, composite processing, sealing heat sealing, electronics, and other industries. It is typically applied to areas requiring anti-sticking, heat sealing, corrosion resistance, or insulation, and its reusable nature makes it easy to replace. During the production and transportation of Teflon tape, conveyor belts and guiding devices are required to ensure the tape remains organized and prevent it from becoming scattered or misaligned.

[0003] The existing Teflon tape transport and guidance equipment has the following problems:

[0004] Existing Teflon tape transport and guidance equipment does not have the ability to eliminate the transport gap between adjacent Teflon tapes. On the one hand, individual Teflon tapes are prone to scattering or jamming during transport; on the other hand, in high-speed packaging or palletizing, it is impossible to provide continuously arranged Teflon tapes, thus affecting the transport efficiency of Teflon tapes.

[0005] Therefore, it cannot meet the actual needs of Teflon belt conveyor operations for guiding equipment at this stage. Summary of the Invention

[0006] In view of the above situation and to overcome the shortcomings of the prior art, this solution provides a Teflon tape transport and guidance device that can eliminate the conveying gap between adjacent Teflon tapes and improve the conveying efficiency of Teflon tapes.

[0007] The technical solution adopted in this solution is as follows: This solution proposes a Teflon tape transport and guidance device, including a conveyor platform, a support base, a limiting conveyor mechanism, and a distance measuring and speed control mechanism. The support base is located on the bottom wall of the conveyor platform. The limiting conveyor mechanism includes a conveying component, a guiding component, and a limiting component. The conveying component is located on the upper wall of the conveyor platform. The guiding component is located on the upper wall of the conveyor platform on both sides of the conveying component. The limiting component is located on the side of the guiding component closer to the conveying component. The distance measuring and speed control mechanism includes a distance measuring component and a speed control component. The distance measuring component is located on the upper wall of the conveyor platform on one side of the guiding component. The speed control component is located on the upper wall of the limiting component.

[0008] As a further preferred embodiment of the present invention, the conveying assembly includes a conveying trough, conveying shafts, conveying toothed rollers, conveying toothed belts, and a drive motor. The conveying trough is located on the upper wall of the conveying platform and is open on three sides. Multiple sets of conveying shafts are rotatably mounted on the inner wall of the conveying trough. The conveying toothed rollers are located on the outer side of the conveying shafts, and the conveying toothed belts are wound around the outer side of the conveying toothed rollers and mesh with the conveying toothed rollers. The drive motor is located at one end of the conveying platform, and the output end of the drive motor is connected to the conveying shaft at one end of the conveying platform. The guiding assembly includes a guide block, a guide rod, a guide plate, and a positioning screw. The guide block is provided on the upper wall of one end of the conveyor table. The guide rod is slidably provided on the end of the guide block away from the conveyor table. The guide plate is provided on the side of the guide rod away from the conveyor table. The positioning bolt is provided through the upper wall of the guide block and is threadedly connected to the guide block. The limiting assembly includes a limiting seat, a limiting rubber wheel and a limiting plate. The limiting seat is provided on the side of the guide rod away from the guide plate. The limiting rubber wheel is rotatably provided on the end of the limiting seat away from the guide rod. The limiting plate is provided between adjacent limiting seats and on the side wall of the limiting seat. The inner side wall of the limiting plate is flush with the limiting rubber wheel.

[0009] In use, the initial distance between the limiting rubber wheels is at its maximum. Adjust the distance between the limiting rubber wheels according to the size of the roll of Teflon tape. The surface of the limiting rubber wheels should fit against the surface of the roll of Teflon tape. Then, rotate the positioning bolts. The positioning bolts are screwed into the guide blocks to fix the guide rods. The output end of the drive motor drives the conveyor toothed rollers to rotate through the conveyor shaft. The conveyor toothed rollers drive the conveyor toothed belt to rotate in a cycle, embedding the roll of Teflon tape into the upper surface of the conveyor toothed belt between the limiting plates. When the roll of Teflon tape passes through the limiting rubber wheels, it drives them to rotate, thus realizing the conveyor toothed belt conveying the roll of Teflon tape.

[0010] Preferably, the ranging component includes a ranging port, a positioning seat, a laser sensor, and a laser receiver. The ranging port is located on the side wall of the limiting plate away from the limiting seat. The positioning seat is located on the upper wall of the conveyor platform on one side of the ranging port. The laser sensor is located on the side wall of the positioning seat at one end of the conveyor platform. The laser receiver is located on the side wall of the positioning seat at the end of the conveyor platform away from the laser sensor. The laser sensor and the laser receiver are arranged opposite to each other. The speed control component includes a speed control frame, a speed limiting electromagnet, a speed control shaft, and a speed control magnet. The speed control frame is located on the upper wall of the limiting seat. The speed limiting electromagnet is located at the end of the speed control frame away from the limiting seat. The speed control shaft is rotatably located on the upper wall of the limiting seat below the speed limiting electromagnet. The end of the speed control shaft away from the speed limiting electromagnet passes through the limiting seat and connects to the limiting rubber wheel. The speed control magnet is located on the upper wall of the speed control shaft. The speed control magnet and the speed limiting electromagnet are arranged opposite to each other.

[0011] In operation, the laser sensor emits a laser signal to the laser receiver through the ranging port. When there is a gap between two adjacent rolls of Teflon tape on the upper surface of the conveyor belt, the laser receiver can receive the laser signal emitted by the laser sensor. When the limiting wheel rotates, it drives the speed control magnet to rotate through the speed control shaft. At this time, the speed limiting electromagnet is energized and generates magnetism. The speed limiting electromagnet and the speed control magnet are set with opposite poles. The speed limiting electromagnet attracts the speed control magnet through magnetic force, increasing the rotational resistance of the limiting wheel and thus reducing the conveying speed of the roll of Teflon tape. Under the obstruction of the limiting wheel, the roll of Teflon tape slips between itself and the conveyor belt. At this time, the conveying speed of the roll of Teflon tape at the inlet end of the conveyor belt is greater than the conveying speed of the roll of Teflon tape in the middle and end of the conveyor belt, making the rolls of Teflon tape stick together and eliminating the gaps between them. The tightly arranged rolls of Teflon tape are equivalent to a whole, and it is not easy for them to be scattered or jammed, thereby improving the guiding and conveying effect of the rolls of Teflon tape.

[0012] Specifically, the support base is equipped with a controller on its side wall.

[0013] The controller is electrically connected to the drive motor, the laser sensor, the laser receiver, and the speed-limiting electromagnet.

[0014] The conveyor belt is made of PTFE material, which has an extremely low coefficient of dynamic friction.

[0015] The beneficial effects achieved by this solution using the above structure are as follows:

[0016] Compared with existing technologies, this solution combines a limiting conveying mechanism with a distance-measuring speed control mechanism. Through the configured conveying, guiding, limiting, distance-measuring, and speed control components, it eliminates the gap between adjacent rolls of Teflon tape during transport, ensuring the stability of the conveying process. By utilizing the duration of the signal received by the laser receiver from the laser sensor, the magnetic attraction strength of the speed-limiting electromagnet to the speed-controlling magnet is correspondingly controlled. This, in turn, matches the interval between two rolls of Teflon tape during slitting and unloading, achieving gapless conveying of the rolls. Therefore, in high-speed packaging or palletizing processes, continuously arranged rolls of Teflon tape can be continuously fed, facilitating continuous production line operation, reducing equipment start-ups and shutdowns, improving the efficiency of subsequent processes, and ensuring the stability of the guided conveying of the rolls of Teflon tape.

[0031] like Figures 1-10 As shown, the proposed solution provides a Teflon tape transport and guidance device, including a conveyor platform 1, a support base 2, a limiting conveying mechanism 3, and a distance-measuring speed control mechanism 19.

[0032] The conveying assembly 4 includes a conveying trough 5, a conveying shaft 6, a conveying toothed roller 7, a conveying toothed belt 8, and a drive motor 9. The conveying trough 5 is located on the upper wall of the conveying platform 1 and is open on three sides.

The guiding assembly 10 includes a guide block 11, a guide rod 12, a guide plate 13, and a positioning bolt 14. Multiple sets of the guide blocks 11 are located on the conveying platform. The upper wall of one end of the guide block 11 has a guide rod 12 slidably disposed at the end of the guide block 11 away from the conveyor table 1, a guide plate 13 disposed on the side of the guide rod 12 away from the conveyor table 1, and a positioning bolt 14 passing through the upper wall of the guide block 11 and threadedly connected to the guide block 11; the limiting assembly 15 includes a limiting seat 16, a limiting rubber wheel 17 and a limiting plate 18, the limiting seat 16 is disposed on the side of the guide rod 12 away from the guide plate 13, the limiting rubber wheel 17 is rotatably disposed at the end of the limiting seat 16 away from the guide rod 12, and the limiting plate 18 is disposed between adjacent limiting seats 16 and on the side wall of the limiting seat 16, with the inner side wall of the limiting plate 18 flush with the limiting rubber wheel 17.

[0033] The ranging assembly 20 includes a ranging port 21, a positioning seat 22, a laser sensor 23, and a laser receiver 24. The ranging port 21 is located on the side wall of the limiting plate 18 away from the limiting seat 16. The positioning seat 22 is located on the upper wall of the conveyor platform 1 on one side of the ranging port 21. The laser sensor 23 is located on the side wall of the positioning seat 22 at one end of the conveyor platform 1. The laser receiver 24 is located on the side wall of the positioning seat 22 at the end of the conveyor platform 1 away from the laser sensor 23. The laser sensor 23 and the laser receiver 24 are arranged opposite to each other. The speed control assembly... Component 25 includes a speed control frame 26, a speed limiting electromagnet 27, a speed control shaft 28, and a speed control magnet 29. The speed control frame 26 is disposed on the upper wall of the limiting seat 16. The speed limiting electromagnet 27 is disposed at the end of the speed control frame 26 away from the limiting seat 16. The speed control shaft 28 is rotatably disposed on the upper wall of the limiting seat 16 below the speed limiting electromagnet 27. The end of the speed control shaft 28 away from the speed limiting electromagnet 27 passes through the limiting seat 16 and is connected to the limiting rubber wheel 17. The speed control magnet 29 is disposed on the upper wall of the speed control shaft 28 and is disposed opposite to the speed limiting electromagnet 27.

[0034] The support base 2 is equipped with a controller 30 on its side wall.

[0035] The controller 30 is electrically connected to the drive motor 9, the laser sensor 23, the laser receiver 24, and the speed limiting electromagnet 27, respectively.

[0036] The conveyor belt 8 is made of PTFE material, which has an extremely low coefficient of dynamic friction.

[0037] In actual use, in the initial state, the distance between the limiting rubber wheels 17 is at its maximum value. According to the specifications and dimensions of the roll of Teflon tape obtained by the slitting production line, the distance between the limiting rubber wheels 17 on both sides is adjusted adaptively so that the surface of the limiting rubber wheels 17 is in contact with the surface of the roll of Teflon tape.

[0038] The operator rotates the positioning bolt 14, which screws into the guide block 11 to fix the guide rod 12. The controller 30 controls the drive motor 9 to start. The output end of the drive motor 9 drives the conveyor toothed roller 7 to rotate through the conveyor shaft 6. The conveyor toothed roller 7 drives the conveyor toothed belt 8 to rotate in a cycle. The slit Teflon tape is embedded in the upper surface of the conveyor toothed belt 8 between the limiting plates 18. Under the limiting and guiding action of the limiting plates 18, the Teflon tape is conveyed from one end of the conveyor table 1 to the other end and enters the clamping and guiding area of ​​the two limiting rubber wheels 17. When the Teflon tape passes through the limiting rubber wheels 17, it drives them to rotate, realizing the conveying operation of the conveyor toothed belt 8 on the Teflon tape.

[0039] Since the rolls of Teflon tape fed onto the upper wall of the conveyor belt 8 from the slitting production line are not continuous, the controller 30 controls the laser sensor 23 and the laser receiver 24 to start. The laser sensor 23 emits a laser signal to the laser receiver 24 through the ranging port 21. When there is a gap between two adjacent rolls of Teflon tape on the upper surface of the conveyor belt 8, the laser receiver 24 can receive the laser signal emitted by the laser sensor 23. The controller 30 synchronously records the duration for which the laser receiver 24 receives the signal emitted by the laser sensor 23.

[0040] When the limiting rubber wheel 17 rotates, it drives the speed control magnet 29 to rotate via the speed control shaft 28. At this time, the controller 30 controls the speed limiting electromagnet 27 to start. The speed limiting electromagnet 27 is energized and generates magnetism. The speed limiting electromagnet 27 and the speed control magnet 29 are set with opposite poles. The speed limiting electromagnet 27 attracts the speed control magnet 29 through magnetic force. The magnetic field strength between the speed limiting electromagnet 27 and the speed control magnet 29 gradually increases, and the rotational resistance of the limiting rubber wheel 17 increases accordingly. The blocking effect on the rolled Teflon tape is simultaneously enhanced. Under the blocking effect of the limiting rubber wheel 17, a relative slippage phenomenon occurs between the rolled Teflon tape and the conveyor toothed belt 8. The conveying speed of the tape gradually decreases with the degree of slippage. The conveying speed of the roll of Teflon tape at the inlet end of belt 8 is greater than that of the roll of Teflon tape at the middle and end of the conveying toothed belt 8. The gap between adjacent rolls of Teflon tape is eliminated, and the rolls of Teflon tape adhere to each other. On the one hand, the tightly arranged rolls of Teflon tape are equivalent to a whole, making it less likely for them to scatter or jam. On the other hand, in high-speed packaging or palletizing, the continuously arranged Teflon tape can achieve continuous feeding without waiting for gaps, which is conducive to assembly line operation, reduces the number of equipment start-ups and shutdowns, improves the efficiency of subsequent processes, and thus improves the guiding and conveying effect of the rolls of Teflon tape. The above operation can be repeated for the next use.

[0042] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
