Description

Technical Field

[0001] This invention relates to the field of conveyor belt production technology, specifically to a calendering device for conveyor belt production and processing that is easy to adjust. Background Technology

[0002] Conveyor belt calendering is a processing method that uses roller-type equipment to plastically deform metal sheets. This method involves feeding the metal sheet between rollers, applying pressure, and causing it to plastically deform under the action of the rollers. This processing method not only improves the plastic deformation capacity of the metal sheet but also makes its surface smoother.

[0003] A search revealed Chinese patent CN222290812U, which discloses an easily adjustable calendering device for conveyor belt production and processing. The device includes a lower connecting part and an upper connecting part, with the upper connecting part positioned above the lower connecting part. Drive screws are connected to both sides of the lower connecting part, with the tops of the drive screws threadedly connected to the upper connecting part. Motors are located on both sides of the bottom of the lower connecting part, with their outputs connected to the drive screws. This device allows the upper connecting part to be adjusted up and down by the motors driving the screws, thereby adjusting the gap between the upper and lower extrusion rollers. Additionally, supports are located on both sides of the front of the lower connecting part, with guide rollers positioned between the supports. These guide rollers can be adjusted up and down by the supports, improving the flexibility of the entire guiding mechanism.

[0004] However, in existing calendering devices, the guide rollers responsible for guiding the calendered conveyor belt can only be adjusted in height, lacking a drive mechanism for the guide rollers. During the calendering process by the upper and lower extrusion rollers, the conveyor belt moves towards the guide rollers. Consequently, during the guidance process by the non-rotating guide rollers, it is not only difficult to ensure that the conveyor belt is smoothly guided and transported, but it is also easy to cause the formed conveyor belt to fold, thus affecting the quality of the subsequently formed conveyor belts. This invention designs a calendering device for conveyor belt production and processing that is easy to adjust, in order to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a calendering device for conveyor belt production and processing that is easy to adjust, thereby solving the problem in the prior art that calendered conveyor belts are difficult to guide and transport stably, thus affecting the quality of the conveyor belts.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] Please see Figures 1-5 A calendering device for conveyor belt production and processing that is easy to adjust, comprising:

[0038] The base plate 1 has a lower calendering frame 2 fixedly connected to its top. The upper calendering frame 3 is located on the top of the lower calendering frame 2. A feeding mechanism is located on one side of the upper calendering frame 3. A lower calendering roller 4 is rotatably connected to the inner cavity of the lower calendering frame 2. An upper calendering roller 5 is rotatably connected to the inner cavity of the upper calendering frame 3. The lower calendering roller 4 and the upper calendering roller 5 are rotatably connected through a limiting shaft 6. A drive motor 7 is fixedly connected to one end of both the lower calendering frame 2 and the upper calendering frame 3.

[0039] The guiding mechanism 8 is located on one side of the lower calendering frame 2 and is used to guide and transport the calendered conveyor belt.

[0040] An adjustment mechanism is located between the lower rolling frame 2 and the upper rolling frame 3, and is used to adjust the rolling thickness of the device.

[0041] The guiding mechanism 8 includes a guide roller 801 rotatably connected to one side of the lower calendering frame 2. The guide roller 801 is driven by a driving assembly. The two ends of the lower calendering frame 2 are symmetrically and rotatably connected to an adjusting arc frame 802. The adjusting arc frame 802 is limited by a limiting assembly. The guide roller 801 is rotatably connected between the adjusting arc frames 802 via a guide shaft 803. The guide shaft 803 is fixedly connected to the guide roller 801. The guide shaft 803 passes through the adjusting arc frame 802, and the intersection is limited by a bearing and rotatably connected.

[0042] The limiting assembly includes a limiting arc shell 804 fixedly connected to both ends of the lower pressing frame 2, an adjusting arc frame 802 passing through the limiting arc shell 804 and the two being slidably connected, one end of the limiting arc shell 804 passing through and screwed with a limiting bolt 805, an adjusting ring 809 fixedly connected to the outer ring of the hexagonal block of the limiting bolt 805, and the center of the adjusting arc frame 802 and the limiting arc shell 804 coinciding with the center of the limiting shaft 6 inside the lower pressing frame 2.

[0043] The drive assembly includes a large sprocket 806 rotatably connected to one end of the lower pressing frame 2, a small sprocket 807 rotatably connected to one end of the adjusting arc frame 802, the large sprocket 806 and the small sprocket 807 being connected by a chain 808, a limiting shaft 6 inside the lower pressing frame 2 passing through the lower pressing frame 2 and fixedly connected to the large sprocket 806, and a guide shaft 803 passing through the adjusting arc frame 802 and fixedly connected to the small sprocket 807.

[0044] The working principle of this invention is as follows: After the distance between the lower calendering roller 4 and the upper calendering roller 5 is adjusted, the drive motor 7 is turned on in conjunction with the limiting shaft 6 to drive the lower calendering roller 4 and the upper calendering roller 5 to rotate in opposite directions. At the same time, the raw material to be calendered into a conveyor belt is fed from the left side between the lower calendering frame 2 and the upper calendering frame 3 through the feeding mechanism, so that the calendered conveyor belt is discharged from the right side. During the process, according to the required discharge height of the conveyor belt, the height of the guide roller 801 on the outer ring of the guide shaft 803 is adjusted in conjunction with the adjusting arc frame 802 in the limiting arc shell 804. Then, the limiting bolt 80 is rotated by the adjusting ring 809. 5. Fix the height position of the guide rollers 801 between the adjusting arc frames 802, and the conveyor belt can be placed on top of the guide rollers 801. At this time, the limit shaft 6 driven by the drive motor 7 will drive the large sprocket 806 to rotate, which in turn, together with the small sprocket 807 and the chain 808, will drive the guide rollers 801 outside the guide shaft 803 to rotate quickly. This will create a speed difference between the calendering roller and the guide roller 801, so that the conveyor belt placed on the guide roller 801 has a force to the right, thereby straightening the conveyor belt and making it stably conveyed to the right, avoiding the folding of the formed conveyor belt and ensuring the quality of the formed conveyor belt. Example 2

[0045] Please see Figures 2-5In this embodiment of the invention, the adjustment mechanism includes lifting grooves 9 opened at both ends of the inner cavity of the lower calendering frame 2. The inner cavity of the lifting groove 9 is slidably connected to a lifting seat 10. The top of the lifting seat 10 is symmetrically and fixedly connected to an adjustment column 11. The adjustment column 11 passes through the lower calendering frame 2 and the two are slidably connected. The top of the adjustment column 11 is fixedly connected to the upper calendering frame 3. The bottom of the inner cavity of the lifting groove 9 is symmetrically opened with two adjustment grooves 12. The inner cavity of the adjustment groove 12 is slidably connected to an adjustment block 13. The inner wall of the lifting groove 9 is provided with a scale 39. When the lifting seat 10 is in the initial position, the top is aligned with the zero scale line of the scale 39. When the upper calendering frame 3 is in the initial position, the lower calendering roller 4 is in contact with the upper calendering roller 5.

[0046] The top of the adjusting block 13 and the bottom of the lifting seat 10 are both fixedly connected to a U-shaped linkage seat 14. The top of the adjusting block 13 and the U-shaped linkage seat 14 at the bottom of the lifting seat 10 are connected by a linkage plate 15. The linkage plate 15 and the U-shaped linkage seat 14 are connected by a linkage shaft 16. The inner cavity of the adjusting groove 12 is rotatably connected to a bidirectional stud 17.

[0047] A servo motor 18 is fixedly connected to one side of the lower pressing frame 2. The output shaft of the servo motor 18 is fixedly connected to a bidirectional stud 17. The bidirectional stud 17 passes through the adjusting block 13 and the two are threadedly connected. Two linkage sprockets 19 are symmetrically connected and rotatably connected to one side of the lower pressing frame 2. The bidirectional stud 17 passes through the lower pressing frame 2 and is fixedly connected to the linkage sprockets 19. The two linkage sprockets 19 are connected by a linkage chain 20.

[0048] The working principle of this invention is as follows: When it is necessary to adjust the distance between the lower calendering roller 4 and the upper calendering roller 5 according to the thickness of the calendered conveyor belt, the servo motor 18 is turned on, and the linkage sprocket 19 and linkage chain 20 drive the two bidirectional studs 17 to rotate, thereby adjusting the position of the adjusting block 13 in the adjusting groove 12. Then, under the action of the U-shaped linkage seat 14, the linkage plate 15 and the linkage shaft 16, the adjusting column 11 at the top of the lifting seat 10 of the lifting groove 9 is moved upward, thereby driving the upper calendering roller 5 to move upward. During the process, the upward movement height of the lifting seat 10 can be precisely controlled by the scale 39, that is, the upward movement height of the upper calendering roller 5 is precisely controlled, which improves the convenience of adjusting this calendering device and achieves the purpose of precise control of the calendering thickness of the conveyor belt.

[0049] Example 3

[0050] Please see Figures 6-9In this embodiment of the invention, the feeding mechanism includes a feeding plate 21 fixedly connected to the inner cavity of the upper calendering frame 3. The feeding plate 21 extends to contact the lower calendering roller 4 and the two are slidably connected. The feeding plate 21 is provided with a conveying component inside. The two ends of the feeding plate 21 are fixedly connected to upright plates 22. The upright plates 22 are symmetrical and slidably connected to a limiting plate 23. A guide plate 33 is fixedly connected to one side of the limiting plate 23. A control arm 24 is fixedly connected to one end of the limiting plate 23. The control arm 24 passes through the upright plate 22 and the two are slidably connected. The control arm 24 is adjusted by a control component.

[0051] The control assembly includes a fixed base 25 fixedly connected to the bottom of the feeding plate 21. A bidirectional lead screw 26 is rotatably connected through the inner cavity of the fixed base 25. Both ends of the bidirectional lead screw 26 pass through the control arm 24 and are threadedly connected. The intersection of the bidirectional lead screw 26 and the fixed base 25 is limited by a first limit bearing 27 and is rotatably connected. A worm gear 28 is rotatably connected to the inner cavity of the fixed base 25. The worm gear 28 is fixedly connected to the bidirectional lead screw 26. A worm 29 is meshed on the outer ring of the worm gear 28. The worm 29 is rotatably connected to the inner cavity of the fixed base 25 through an adjusting shaft 30. The adjusting shaft 30 passes through the fixed base 25 and is limited by a second limit bearing 31 at its intersection and is rotatably connected. A handwheel 32 is fixedly connected to one side of the adjusting shaft 30.

[0052] The conveying assembly includes a feeding trough 34 opened on the top of the feeding plate 21. The inner cavity of the feeding trough 34 is symmetrical and rotatably connected to a rotating roller 35. A conveyor belt 36 is provided on the outside of the rotating roller 35. The rotating roller 35 is rotatably connected to the inner cavity of the feeding trough 34 through a rotating shaft 37. A motor 38 is fixedly connected to one end of the feeding plate 21, and the conveyor belt 36 is driven by the motor 38.

[0053] The working principle of this invention is as follows: When the calendered raw material is placed on the feeding plate 21, the handwheel 32, in conjunction with the limiting bearing 31, drives the worm gear 29 outside the adjusting shaft 30 to rotate. Then, under the action of the worm wheel 28, it drives the bidirectional lead screw 26 to rotate. This allows the control arm 24 to adjust the distance between the limiting plates 23 between the vertical plates 22, thereby limiting the raw material from both ends according to the width of the raw material to be calendered, thus improving the stability of the raw material. Then, the motor 38 is turned on to drive the rotating shaft 37 and the rotating roller 35, which, in conjunction with the conveyor belt 36 in the feeding trough 34, transports the raw material between the lower calendering roller 4 and the upper calendering roller 5, facilitating the calendering and forming of the conveyor belt and improving the applicability and practicality of this calendering device.

[0054] When using this easily adjustable conveyor belt for production and processing, the upper calendering frame 3 at the top of the lower calendering frame 2 is adjusted via the adjustment mechanism. This adjusts the distance between the lower calendering roller 4 and the upper calendering roller 5, achieving the purpose of controlling the thickness of the calendered conveyor belt and improving the practicality and applicability of this calendering device. After the distance between the lower calendering roller 4 and the upper calendering roller 5 is adjusted, the drive motor 7 is turned on in conjunction with the limiting shaft 6, causing the lower calendering roller 4 and the upper calendering roller 5 to rotate in opposite directions. At the same time, the raw material to be calendered into a conveyor belt is fed from the left side between the lower calendering frame 2 and the upper calendering frame 3 through the feeding mechanism, so that the calendered conveyor belt is exited from the right side. During the process, according to the required exit height of the conveyor belt, the adjusting arc frame 802 inside the limiting arc shell 804 is used to adjust the distance. The height of the guide roller 801 on the outer ring of the guide shaft 803 is adjusted, and then the height position of the guide roller 801 between the adjusting arc frame 802 is fixed by rotating the limiting bolt 805 through the adjusting ring 809. The conveyor belt can then be placed on top of the guide roller 801. At this time, the limiting shaft 6 driven by the drive motor 7 will drive the large sprocket 806 to rotate, which, in conjunction with the small sprocket 807 and the chain 808, will drive the guide roller 801 outside the guide shaft 803 to rotate rapidly. This creates a speed difference between the calendering roller and the guide roller 801, resulting in a rightward force on the conveyor belt placed on the guide roller 801. This straightens the conveyor belt, ensuring stable transport to the right and preventing the formed conveyor belt from collapsing, thus guaranteeing the quality of the formed conveyor belt. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
