Description

Technical Field

[0001] This utility model relates to the field of food processing machinery technology, and in particular to a conveyor belt tension adjustment device. Background Technology

[0002] In the high-speed, continuous production of the food processing industry, the dynamic stability of conveyor belt tension directly affects production efficiency and food safety. However, traditional tensioning devices mostly rely on fixed mechanical adjustment structures (such as screws or counterweights), which require manual adjustments and have low precision. This can lead to the conveyor belt being in an overly tight state (accelerating wear and shortening lifespan) or an overly loose state (causing slippage and deviation). This can result in product conveying interruptions and reduced production capacity, or even equipment jamming due to conveyor belt misalignment, and may even cause material spillage, contamination, or mechanical damage, leading to safety accidents. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a conveyor belt tension adjustment device.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] This utility model provides a conveyor belt tension adjustment device, including a frame and a conveyor belt and a drive assembly mounted on the frame. The conveyor belt is used to drive and transport external food via the drive assembly. A first roller is provided on the frame, and a first shaft is rotatably mounted on the first roller. The first shaft is slidably disposed relative to the frame. The tension of the conveyor belt can be adjusted by adjusting the sliding position of the first shaft on the frame.

[0006] Preferably, the frame is provided with a first groove for accommodating the first shaft. The first groove is strip-shaped to allow the first shaft to slide relative to the frame. By providing a strip-shaped first groove on the frame to accommodate the first shaft, the first shaft is provided with a track for sliding relative to the frame, thereby achieving the technical effect that the first shaft can slide along a predetermined path to adjust the tension of the conveyor belt.

[0007] Preferably, the first shaft is cylindrical, and a second groove is formed on the outer wall of the first shaft. The first shaft abuts against the inner wall of the first groove via the inner wall of the second groove, so as to ensure that the first shaft is slidably set relative to the frame. By forming a second groove on the outer wall of the cylindrical first shaft and using the inner wall of the second groove to abut against the inner wall of the first groove, the first shaft is stably and slidably set on the frame, thereby achieving the technical effect that the first shaft can slide smoothly to accurately adjust the tension of the conveyor belt.

[0008] Preferably, the frame is further provided with a second adjustment structure, which includes a third roller body slidably disposed on the frame. The conveyor belt is disposed on the third roller body, and the third roller body is slidably used to resist the conveyor belt to adjust the tension. By providing a second adjustment structure including a slidable third roller body on the frame and disposing of the conveyor belt on the third roller body, the tension is adjusted by using the sliding resistance of the third roller body to resist the conveyor belt. This achieves the technical effect of adding another way to adjust the tension of the conveyor belt, making the tension adjustment more flexible and comprehensive.

[0009] Preferably, the frame is equipped with a slide rail, and the end of the third roller is slidably mounted on the slide rail along its length. A bearing is also provided between the third roller and the slide rail. The third roller slides and rotates relative to the slide rail via the bearing. By setting a slide rail on the frame, slidably mounting the end of the third roller on the slide rail, and providing a bearing to allow the third roller to slide and rotate relative to the slide rail, the third roller achieves the dual function of both stable sliding and flexible rotation. This ensures that the third roller can move smoothly without affecting the normal operation of the conveyor belt when adjusting the tension of the conveyor belt.

[0010] Preferably, the frame is also provided with a first driving component for driving the reciprocating motion of the third roller. The first driving component is used to realize the automatic adjustment of the tension of the conveyor belt as needed. By setting the first driving component for driving the reciprocating motion of the third roller on the frame, the tension of the conveyor belt can be automatically adjusted according to actual needs, thereby achieving the technical effect of improving the tension adjustment efficiency, reducing manual operation, and ensuring the stable operation of the conveyor belt.

[0011] Preferably, the first driving component is a cylinder rotatably mounted on the frame. The extension and retraction direction of the cylinder output end is parallel to the sliding direction of the third roller relative to the frame. By designing the first driving component as a cylinder rotatably mounted on the frame and whose extension and retraction direction of the output end is parallel to the sliding direction of the third roller, the cylinder can accurately and directly drive the third roller to slide, thereby achieving efficient and accurate adjustment of the conveyor belt tension.

[0012] Preferably, the output end of the cylinder is provided with a fisheye connector, and the third roller is rotated relative to the cylinder via the fisheye connector. By using the technical means of setting a fisheye connector at the output end of the cylinder so that the third roller can rotate flexibly relative to the cylinder while being driven and slid by the cylinder, the technical effect of reducing friction between components and ensuring smooth adjustment is achieved during the adjustment of the conveyor belt tension.

[0013] Preferably, the output end of the drive assembly is provided with a fourth roller that contacts the conveyor belt, and the first roller is located between the first roller and the fourth roller and is not collinear with the first roller and the fourth roller. By setting a fourth roller that contacts the conveyor belt at the output end of the drive assembly and setting the first roller between the first roller and the fourth roller and not collinear with the first roller, the transmission path of the conveyor belt is reasonably arranged, and the force distribution of the conveyor belt is optimized. This achieves the technical effect of making the conveyor belt run more smoothly, reducing wear, and improving conveying efficiency.

[0014] Preferably, the third roller is located between the second and fourth rollers and is not collinear with the second and fourth rollers. The fourth roller is not collinear with the first and third rollers. By adopting the technical means of setting the third roller between the second and fourth rollers and not collinear with them, while ensuring that the fourth roller is not collinear with the first and third rollers, the conveyor belt drive structure is further optimized.

[0015] The beneficial effects of this utility model are as follows: In the conveyor belt tension adjustment device, a conveyor belt for conveying external food and driven by a drive component is set on the frame. At the same time, a first roller is set on the frame, and a first shaft is rotatably set on the first roller and slidably set relative to the frame. By adjusting the sliding position of the first shaft on the frame, the wrap angle and force of the conveyor belt at the first roller are changed, thereby achieving the technical effect of adjusting the tension of the conveyor belt. This ensures that the conveyor belt can stably and efficiently convey external food and avoids problems such as conveyor belt slippage and deviation caused by improper tension.

Detailed Implementation

[0025] Reference Figures 1 to 5 A conveyor belt tension adjustment device includes a frame 1, a conveyor belt 2 and a drive assembly 3 mounted on the frame 1. The conveyor belt 2 is used to drive and convey external food via the drive assembly 3. A first roller 41 is provided on the frame 1, and a first shaft 411 is rotatably mounted on the first roller 41. The first shaft 411 is slidably disposed relative to the frame 1. The tension of the conveyor belt 2 can be adjusted by adjusting the sliding position of the first shaft 411 on the frame 1.

[0026] With the above-described structural configuration, in use, the conveyor belt tension adjustment device includes a conveyor belt 2 for conveying external food and driven by the drive assembly 3, mounted on the frame 1. A first roller 41 is also mounted on the frame 1, and a first shaft 411 is rotatably mounted on the first roller 41 and slidably mounted relative to the frame 1. By adjusting the sliding position of the first shaft 411 on the frame 1, the wrap angle and force of the conveyor belt 2 at the first roller 41 are changed, thereby achieving the technical effect of adjusting the tension of the conveyor belt 2. This ensures that the conveyor belt 2 can stably and efficiently convey external food, avoiding problems such as slippage and deviation of the conveyor belt 2 due to improper tension.

[0027] Specifically, the first shaft 411 and the first groove 42 belong to the first adjustment structure 4.

[0028] Specifically, the frame 1 is provided with a first groove 42 for accommodating the first shaft 411. The first groove 42 is strip-shaped and is used for the first shaft 411 to slide relative to the frame 1. By setting the first groove 42 on the frame 1 to accommodate the first shaft 411, the first shaft 411 is provided with a track for sliding relative to the frame 1, thereby achieving the technical effect that the first shaft 411 can slide along a predetermined path to adjust the tension of the conveyor belt 2.

[0029] Specifically, a central control mechanism is also installed on rack 1, but we will not go into details here.

[0030] Specifically, the first shaft 411 is cylindrical, and a second groove 412 is formed on the outer wall of the first shaft 411. The first shaft 411 abuts against the inner wall of the first groove 42 via the inner wall of the second groove 412 to ensure that the first shaft 411 is slidably set relative to the frame 1. By using the technical means of forming a second groove 412 on the outer wall of the cylindrical first shaft 411 and using the inner wall of the second groove 412 to abut against the inner wall of the first groove 42, the first shaft 411 is stably and slidably set on the frame 1, thereby achieving the technical effect that the first shaft 411 can slide smoothly to accurately adjust the tension of the conveyor belt 2.

[0031] Specifically, the frame 1 is also provided with a second adjustment structure 5. The second adjustment structure 5 includes a third roller 51 that is slidably disposed on the frame 1. The conveyor belt 2 is disposed on the third roller 51. The third roller 51 is slidably used to stop the conveyor belt 2 to adjust the tension. By setting the second adjustment structure 5, which includes a slidable third roller 51, on the frame 1 and disposing of the conveyor belt 2 on the third roller 51, the tension is adjusted by using the sliding stop of the third roller 51 against the conveyor belt 2. This achieves the technical effect of adding a way to adjust the tension of the conveyor belt 2, making the tension adjustment more flexible and comprehensive.

[0032] Specifically, the frame 1 is provided with a slide rail 53, and the end of the third roller 51 in the length direction is slidably mounted on the slide rail 53. A bearing 511 is also provided between the third roller 51 and the slide rail 53. The third roller 51 is slidably and rotatably mounted relative to the slide rail 53 via the bearing 511. By setting the slide rail 53 on the frame 1, slidably mounting the end of the third roller 51 on the slide rail 53, and setting the bearing 511 to make the third roller 51 slide and rotate relative to the slide rail 53, the third roller 51 can achieve the dual function of both stable sliding and flexible rotation. Thus, when adjusting the tension of the conveyor belt 2, the third roller 51 can move smoothly without affecting the normal operation of the conveyor belt 2.

[0033] Specifically, the frame 1 is also equipped with a first drive component 52 for driving the third roller 51 to reciprocate. The first drive component 52 is used to automatically adjust the tension of the conveyor belt 2 as needed. By setting the first drive component 52 for driving the third roller 51 to reciprocate on the frame 1, the tension of the conveyor belt 2 can be automatically adjusted according to actual needs, thereby achieving the technical effect of improving the tension adjustment efficiency, reducing manual operation, and ensuring the stable operation of the conveyor belt 2.

[0034] Specifically, the first driving component 52 is a cylinder rotatably mounted on the frame 1. The extension and retraction direction of the cylinder output end is parallel to the sliding direction of the third roller 51 relative to the frame 1. By designing the first driving component 52 as a cylinder rotatably mounted on the frame 1 and whose extension and retraction direction of the output end is parallel to the sliding direction of the third roller 51, the cylinder can accurately and directly drive the third roller 51 to slide, thereby achieving efficient and accurate adjustment of the tension of the conveyor belt 2.

[0035] Specifically, the output end of the cylinder is equipped with a fisheye connector, and the third roller 51 is rotated relative to the cylinder via the fisheye connector. By using the technical means of setting a fisheye connector at the output end of the cylinder, the third roller 51 can rotate flexibly relative to the cylinder while sliding with the cylinder. This achieves the technical effect of reducing friction between components and ensuring smooth adjustment during the adjustment of the tension of the conveyor belt.

[0036] Specifically, the frame 1 is also equipped with a compensation mechanism 6, which is used to adjust the effective transport length of the conveyor belt 2; the compensation mechanism 6 includes a plate and a drive motor for driving the plate to reciprocate.

[0037] Specifically, when the compensation mechanism 6 adjusts the effective transport length of the conveyor belt 2, the second adjustment structure 5 works synchronously to achieve dynamic adjustment of the conveyor belt 2. A central control module is provided on the frame 1 to control the operation of the device, which will not be elaborated on here.

[0038] Specifically, the conveyor belt 2 is provided with a first roller 21 and a second roller 22 rotatably mounted on the frame 1. The output end of the drive assembly 3 is provided with a fourth roller 31 that is in contact with the conveyor belt 2. The first roller 41 is located between the first roller 21 and the fourth roller 31 and is not collinear with them. By setting the fourth roller 31 in contact with the conveyor belt 2 at the output end of the drive assembly 3 and setting the first roller 41 between the first roller 21 and the fourth roller 31 and not collinear with them, the transmission path of the conveyor belt 2 is rationally arranged, and the force distribution of the conveyor belt 2 is optimized. This achieves the technical effect of making the conveyor belt 2 run more smoothly, reducing wear, and improving conveying efficiency.

[0039] Specifically, the third roller 51 is located between the second roller 22 and the fourth roller 31 and is not collinear with the second roller 22 and the fourth roller 31. The fourth roller 31 is not collinear with the first roller 41 and the third roller 51. By adopting the technical means of setting the third roller 51 between the second roller 22 and the fourth roller 31 and not collinear with the first roller 41 and the third roller 51, the transmission structure of the conveyor belt 2 is further optimized.
