Description

Technical Field

[0001] This utility model relates to the field of thermal insulation strip production technology, and in particular to a traction device for thermal insulation strip production. Background Technology

[0002] In the production process of thermal insulation strips, the traction device is a key piece of equipment used to transport and pull the thermal insulation strips. It achieves stable transmission of the thermal insulation strips through the friction between the traction belt and the thermal insulation strips, so as to ensure the continuity of production and product quality. In existing traction devices used for thermal insulation strip production, the traction belt, as the component that directly contacts the thermal insulation strip and provides traction force, needs to continuously rub against the surface of the thermal insulation strip during long-term use, causing the contact parts to gradually wear down. In addition, to ensure reliable traction of the thermal insulation strip, the traction belt usually needs to withstand a certain clamping force. Long-term stress can easily cause fatigue aging of the traction belt. Furthermore, in order to cool the thermal insulation strip or traction device during the production process, the traction belt may come into contact with cooling water, which further accelerates the aging and deterioration of its material. As a result, after a period of use, the traction performance of the traction belt will decrease significantly and will not be able to meet production requirements, necessitating replacement.

[0003] However, in terms of structural design, the side plates used for installing and fixing the traction wheels are usually fastened with multiple external screws. When replacing the traction belt, these screws must be removed one by one using special tools before the side plates can be removed. The operation is cumbersome and time-consuming, affecting production efficiency. At the same time, the distance between the two traction wheels in the traction device is fixed and cannot be adjusted. Therefore, when removing the old traction belt from the two traction wheels or installing the new traction belt, the fixed distance restricts the space for disassembly and assembly due to the tension and rigidity of the traction belt itself, increasing the difficulty of operation and further reducing replacement efficiency. Therefore, a traction device for the production of thermal insulation strips is proposed to solve the above problems. Utility Model Content

By adjusting the distance between the two traction wheels through the telescopic component, the old traction belt can be easily removed and the new traction belt can be installed, reducing operation steps, shortening replacement time, and improving maintenance efficiency.

[0005] (II) Technical Solution This utility model provides a traction device for producing heat insulation strips, including a base. The four corners of the upper end of the base are respectively connected to a top plate by vertically arranged support rods. A bidirectional lifting mechanism is installed between the top plate and the base. The bidirectional lifting mechanism is equipped with symmetrically arranged traction mechanisms on both sides of the lifting end.

[0006] Preferably, the bidirectional lifting mechanism includes a first drive motor, a bidirectional threaded rod, and a lifting threaded sleeve. The first drive motor is fixedly installed on the top of the top plate. The bidirectional threaded rod is rotatably connected between the top plate and the base through a bearing. The output shaft of the first drive motor passes through the top plate and is coaxially and fixedly connected to the upper end of the bidirectional threaded rod. There are two lifting threaded sleeves, which are threaded onto the outer end face of the bidirectional threaded rod. The two lifting threaded sleeves are respectively fixedly connected to the mounting plate that is adapted to them.

[0007] Preferably, the two lifting threaded sleeves are symmetrically distributed based on the central axis of the support rod, and the thread direction of the bidirectional threaded rod is symmetrically arranged based on the central axis of the support rod. Guide members are installed between the top plate and the base and on both sides of the bidirectional threaded rod. The guide members include a first slide rod, which is vertically fixed between the top plate and the base. Two lifting slide sleeves are slidably installed on the outer wall of the first slide rod, and the two lifting slide sleeves are respectively fixedly connected to the mounting plate that is adapted to them.

[0008] Preferably, the guide assembly includes a mounting bracket and a second slide rod. The mounting bracket is fixedly installed on the outer wall of the mounting plate and located outside the slot.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: 1.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1-5 As shown, the present invention proposes a traction device for producing heat insulation strips, including a base 9. The four corners of the upper end of the base 9 are respectively connected to the top plate 2 by vertically arranged support rods 7. A bidirectional lifting mechanism is installed between the top plate 2 and the base 9. Symmetrically arranged traction mechanisms are installed on the lifting ends on both sides of the bidirectional lifting mechanism; The traction mechanism includes symmetrically distributed mounting plates 1, traction wheels 20, and a second motor 12. The symmetrically distributed mounting plates 1 are fixedly connected by multiple connecting rods 21. One end of each symmetrically distributed mounting plate 1 has a slot 16. The second motor 12 is installed on the side of one of the mounting plates 1. There are two traction wheels 20. The two sides of one traction wheel 20 are located between the two slots 16, and the two ends are rotatably connected to the second moving blocks 18. The other traction wheel 20 is rotatably connected to the end of the symmetrically distributed mounting plate 1 away from the slot 16, and one end of the traction wheel 20 is coaxially connected to the output shaft of the second motor 12. A traction belt 19 connected to the two traction wheels 20 is sleeved between the outer end faces of the two traction wheels 20. Both sides of the mounting plate 1 are equipped with guide components that are compatible with the slot 16 on the outer side, and both guide components are slidably connected to the second moving blocks 18 on both sides respectively. A telescopic assembly is also installed on the outer side of the mounting plate 1 on one side, and the moving end of the telescopic assembly is fixedly connected to the second moving block 18 that cooperates with it.

[0022] In this utility model, the height position of the two-way lifting mechanism can be adjusted to meet the traction requirements of the heat insulation strip under different production scenarios. When the traction mechanism is working, the second motor 12 drives the traction wheel 20 connected to it to rotate, and drives another traction wheel 20 to rotate synchronously through the traction belt 19, thereby realizing the traction and transportation of the heat insulation strip.

[0023] The guide assembly provides a stable sliding guide for the second moving block 18, while the telescopic assembly can push the second moving block 18 to move within the slot, thereby adjusting the distance between the two traction wheels 20. This allows for easy removal of the old traction belt 19 and installation of the new traction belt 19, reducing operation steps, shortening replacement time, and improving maintenance efficiency.

[0024] Among them, the anti-slip texture on the inner wall of the traction belt 19 is adapted to the outer end face of the traction wheel 20; In this invention, the two second motors 12 are driven by the same electrical control system. The system includes a PLC controller and a motor driver. The speed, direction and start and stop time of the two second motors 12 are precisely controlled by a preset program. The PLC controller sends the same control signal to the motor drivers on both sides. The motor drivers convert the signal into the corresponding current output, driving the two second motors 12 to run at the same speed and in opposite directions. The second motors 12 are servo motors.

[0025] In an optional embodiment, the bidirectional lifting mechanism includes a first drive motor 4, a bidirectional threaded rod 3, and a lifting threaded sleeve 11. The first drive motor 4 is fixedly installed on the top of the top plate 2. The bidirectional threaded rod 3 is rotatably connected between the top plate 2 and the base 9 through a bearing. The output shaft of the first drive motor 4 passes through the top plate 2 and is coaxially fixedly connected to the upper end of the bidirectional threaded rod 3. There are two lifting threaded sleeves 11, which are threaded on the outer end face of the bidirectional threaded rod 3. The two lifting threaded sleeves 11 are respectively fixedly connected to the mounting plate 1 that is adapted to them.

[0026] It should be noted that the first drive motor 4 drives the bidirectional threaded rod 3 to rotate, which in turn drives the two lifting threaded sleeves 11 to move symmetrically in opposite directions along the axis of the bidirectional threaded rod 3, thereby realizing the adjustment of the distance between the two traction mechanisms and providing sufficient operating space when replacing the traction belt.

[0027] In an optional embodiment, two lifting threaded sleeves 11 are symmetrically distributed based on the central axis of the support rod 7, and the thread direction of the bidirectional threaded rod 3 is symmetrically set based on the central axis of the support rod 7. Guide members are installed between the top plate 2 and the base 9 and on both sides of the bidirectional threaded rod 3. The guide members include a first slide rod 5, which is vertically fixed between the top plate 2 and the base 9. Two lifting slide sleeves 10 are slidably installed on the outer wall of the first slide rod 5, and the two lifting slide sleeves 10 are respectively fixedly connected to the mounting plate 1 that is adapted to them.

[0028] It should be noted that, since the two lifting threaded sleeves 11 are symmetrically distributed based on the central axis of the support rod 7, and the thread direction of the bidirectional threaded rod 3 is set in opposite directions with the central axis of the support rod 7 as the axis of symmetry, when the first drive motor 4 drives the bidirectional threaded rod 3 to rotate, the two lifting threaded sleeves 11 will produce displacements in opposite directions along the axial direction of the bidirectional threaded rod 3 under the action of the thread. That is, when one lifting threaded sleeve 11 moves upward, the other lifting threaded sleeve 11 moves downward synchronously, thereby driving the traction mechanisms on both sides to move closer or further away from each other, thereby adjusting the distance between the traction mechanisms on both sides. Meanwhile, the guide component installed between the top plate 2 and the base 9 plays a key guiding role in the lifting and lowering movement of the traction mechanism. The first slide rod 5 is vertically fixed between the top plate 2 and the base 9, and it is parallel to the axis of the bidirectional threaded rod 3. The lifting slide sleeve 10 is fixedly connected to the mounting plate 1 and is slidably sleeved on the outer wall of the first slide rod 5, which restricts the direction of the mounting plate 1 during the lifting process and ensures that the mounting plate 1 can only move in a straight line in the vertical direction. The first slide rods 5 on both sides are located on both sides of the bidirectional threaded rod 3, and together with the lifting slide sleeve 10 and the mounting plate 1, they ensure the stability of the mounting plate 1 when it is raised or lowered.

[0029] In an optional embodiment, the guide assembly includes a mounting bracket 6 and a second slide rod 17. The mounting bracket 6 is fixedly mounted on the outer wall of the mounting plate 1 and located outside the slot 16. The second slide rod 17 is fixedly mounted between the inner walls of the mounting bracket 6. The second moving block 18 is slidably sleeved on the outer wall of the second slide rod 17 that is adapted to it.

[0030] It should be noted that the second slide rod 17 is horizontally fixed between the inner walls of the mounting bracket 6, and the second moving block 18 is slidably sleeved on the outer wall of the second slide rod 17. Its function is to provide guidance for the movement of the traction wheel 20 and ensure that the traction wheel 20 remains horizontal and stable during the adjustment process.

[0031] In an optional embodiment, the telescopic assembly includes an electric push rod 8, a fixed plate 14, a connecting block 13, and a first moving block 15. The fixed plate 14 is fixedly installed on the outer wall of the rear mounting plate 1. The electric push rod 8 is fixedly installed on the outer side of the fixed plate 14. The telescopic shaft of the electric push rod 8 passes through the fixed plate 14 and is fixedly connected to the first moving block 15. Both sides of the first moving block 15 are fixedly connected to the sides of a second moving block 18 that is adapted to it through the connecting block 13.

[0032] It should be noted that the extension and retraction of the electric push rod 8 can drive the second moving block 18 to slide along the second slide rod 17, thereby adjusting the distance between the two traction wheels 20, reducing the tension of the traction belt 19, facilitating disassembly and assembly operations, and improving replacement efficiency.

[0033] In an optional embodiment, a plurality of driven wheels 22 are rotatably connected between the two mounting plates 1 and inside the traction belt 19, and the plurality of driven wheels 22 are equidistantly distributed.

[0034] It should be noted that the driven wheel 22 has a cylindrical structure and is equidistantly distributed along the length of the mounting plate 1. Its outer surface is in contact with the inner wall of the traction belt 19, which can effectively support the traction belt 19, prevent the traction belt 19 from deforming under force, and ensure the stability of the traction process.

[0035] Working principle: During normal traction operation, the second motors 12 on both sides are started. The second motors 12 on both sides drive the traction wheels 20 connected to them to rotate. Under the transmission action of the traction belt 19, the other traction wheel 20 rotates accordingly, so that the traction belt 19 continues to run. When the heat insulation strip is located between the continuously running traction belt 19, due to the anti-slip texture on the inner wall of the traction belt 19 and its tight fit with the traction wheel 20, it can stably drive the heat insulation strip forward to achieve the traction function.

[0036] When it is necessary to adjust the distance between the two traction mechanisms to accommodate heat insulation strips of different specifications, the first drive motor 4 is started. The first drive motor 4 drives the bidirectional threaded rod 3 to rotate. Since the threads of the two lifting threaded sleeves 11 are opposite, they will move symmetrically in opposite directions along the axis of the bidirectional threaded rod 3, thereby driving the traction mechanisms on both sides to move closer or further away from each other. At the same time, the lifting sliding sleeve 10 slides along the first sliding rod 5 to provide guidance for the movement of the traction mechanism and ensure that the adjustment process is smooth.

[0037] When replacing the traction belt 19, operate the telescopic assembly to activate the electric push rod 8. The telescopic shaft of the electric push rod 8 extends and retracts, causing the first moving block 15 to move. This, through the connecting block 13, causes the second moving block 18 to slide along the second slide rod 17, thereby adjusting the distance between the two traction wheels 20. Increasing the distance reduces the tension of the traction belt 19, making it easier to remove the old traction belt 19. When installing the new traction belt 19, first place it on the two traction wheels 20, then adjust the distance using the electric push rod 8 to tension the traction belt 19. This improves replacement efficiency. During the movement of the traction wheel 20, the guide assembly ensures that the second moving block 18 slides stably along the second slide bar 17, keeping the traction wheel 20 horizontal and ensuring the normal transmission of the traction belt 19. The driven wheel 22 provides support inside the traction belt 19, preventing deformation of the traction belt 19 under force and ensuring the smoothness of the traction process.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
