Description

Technical Field

[0001] This utility model belongs to the field of transmission equipment technology, specifically relating to a circular belt conveyor. Background Technology

[0002] The circular belt conveyor is a type of tableware conveyor commonly used in commercial kitchens. The conveyor body is a circular belt made of polyurethane material with a diameter of 15mm. This circular belt is elastic and will gradually stretch over a long period of use, thus reducing the driving friction and causing the circular belt to slip on the drive wheel, making it difficult to operate normally.

[0003] In the prior art, in order to solve the above problems, the tension wheel is usually mounted on a bracket and has an elongated hole. When slippage occurs, the position of the tension wheel is manually adjusted to compensate for the stretching of the belt. Utility Model Content

[0004] The purpose of this invention is to provide a circular belt conveyor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A circular belt conveyor includes a conveyor frame, an internal mounting bracket, a drive unit above the mounting bracket, a transmission belt connected to the output end of the drive unit, a tensioning assembly connected to the transmission belt, the tensioning assembly including a tensioning bracket, a set of parallel tensioning shafts on the tensioning bracket, a tensioning pulley at the end of the tensioning shaft away from the tensioning bracket, the tensioning pulley being connected to the transmission belt, and an adjusting spring between the two sets of tensioning shafts.

[0007] By adopting the above technical solution: when in use, the transmission belt rotates under the drive of the drive unit, which in turn drives the tension wheel to rotate. When the tension wheel rotates, it causes the tension shaft to shift and causes the adjusting spring to stretch, thereby achieving the effect of automatic adjustment and compensation of the transmission belt.

[0008] Preferably, a tension sensor is provided between the two tensioning shafts, and a controller is provided on one side of the conveyor frame, with the tension sensor electrically connected to the controller.

[0009] By adopting the above technical solution, the tension sensor can detect the tension between the two tension shafts. When the tension sensor detects that the tension is lower than the set value, it sends a signal to the controller to remind the operator to carry out maintenance.

[0010] Preferably, the drive unit includes a drive motor, a reducer, and drive wheels. The reducer is mounted on the mounting bracket, the output end of the drive motor is connected to the reducer, and drive wheels are provided on both sides of the reducer. The drive wheels are frictionally connected to the transmission belt.

[0011] By adopting the above technical solution: the drive motor rotates, and after being reduced in speed by the reducer, it drives the drive wheels on both sides to rotate synchronously. Under the drive of the drive wheels, the transmission belt rotates.

[0012] Preferably, the transmission belt located between the drive wheel and the tension wheel is U-shaped.

[0013] By adopting the above technical solution, the U-shaped design increases the wrap angle between the transmission belt and the drive wheel to over 180°, significantly improving friction.

[0014] Preferably, the conveyor frame is further provided with support wheels at both ends, and the support wheels are frictionally connected to the transmission belt.

[0015] By adopting the above technical solution, the support wheels at both ends can provide good support and guidance for the transmission belt during operation.

[0016] Preferably, the conveyor frame has a plurality of track rollers arranged along its length, and the transmission belt is located inside the track rollers.

[0017] By adopting the above technical solution, the track pad wheel can play a limiting and guiding role for the transmission belt, further improving the stability of the transmission belt movement.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] This circular belt conveyor solves the slippage problem caused by the easy stretching of traditional polyurethane circular belts through a tensioning component, significantly improving the stability and reliability of operation. Combined with real-time monitoring by a tension sensor, it realizes intelligent monitoring and early warning of tension, shifting from passive maintenance to proactive preventive maintenance. The U-shaped wrap angle design increases friction and the multi-stage support guide wheel system further ensures the smooth and efficient operation of the drive belt in long-distance transportation, effectively reducing maintenance frequency and downtime risk.

[0024] The following will refer to the appendix in the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The specific embodiments described herein are merely used to explain this utility model and are not intended to limit this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example:

[0026] like Figures 1-3 As shown, this utility model provides a circular belt conveyor, including a conveyor frame 1, an installation bracket 2 inside the conveyor frame 1, a drive unit 3 above the installation bracket 2, a transmission belt 4 connected to the output end of the drive unit 3, a tensioning assembly 5 connected to the transmission belt 4, the tensioning assembly 5 including a tensioning bracket 51, a set of parallel tensioning shafts 52 on the tensioning bracket 51, a tensioning wheel 53 at the end of the tensioning shaft 52 away from the tensioning bracket 51, the tensioning wheel 53 being connected to the transmission belt 4, and an adjusting spring 54 between the two sets of tensioning shafts 52.

[0027] When in use, the drive belt 4 rotates under the drive of the drive unit 3, which in turn drives the tension wheel 53 to rotate. When the tension wheel 53 rotates, it causes the tension shaft 52 to move and causes the adjusting spring 54 to stretch, thereby achieving the effect of automatic adjustment and compensation of the drive belt 4.

[0028] A tension sensor 55 is installed between the two tensioning shafts 52. A controller 6 is installed on one side of the conveyor frame 1. The tension sensor 55 is electrically connected to the controller 6. The tension sensor 55 can detect the tension between the two tensioning shafts 52. When the tension sensor 55 detects that the tension is lower than the set value, it sends a signal to the controller 6 to remind the operator to carry out maintenance.

[0029] The drive unit 3 includes a drive motor 31, a reducer 32, and drive wheels 33. The reducer 32 is mounted on the mounting bracket 2. The output end of the drive motor 31 is connected to the reducer 32. Drive wheels 33 are provided on both sides of the reducer 32. The drive wheels 33 are frictionally connected to the transmission belt 4. When the drive motor 31 rotates, it is reduced in speed by the reducer 32, which drives the drive wheels 33 on both sides to rotate synchronously. Under the drive of the drive wheels 33, the transmission belt 4 rotates.

[0030] The transmission belt 4 located between the drive wheel 33 and the tension wheel 53 is U-shaped. The U-shaped design increases the wrap angle between the transmission belt 4 and the drive wheel 33 to more than 180°, which significantly improves the friction.

[0031] Support wheels 7 are also provided at both ends of the conveyor frame 1. The support wheels 7 are frictionally connected to the transmission belt 4. The support wheels 7 at both ends can provide good support and guidance for the transmission belt 4 during operation.

[0032] Several guide rollers 8 are arranged along the length of the conveyor frame 1, and the drive belt 4 is located inside the guide rollers 8. The guide rollers 8 can limit and guide the drive belt 4, further improving the stability of the drive belt 4's movement.

[0033] When the drive motor 31 is running, the reducer 32 rotates clockwise or counterclockwise, driving the drive wheel 33 to rotate. Friction then drives the transmission belt 4 in a linear motion. Since the transmission belt 4 is a closed-loop structure, this process continuously repeats. The transmission belt 4 is fixed in a U-shape by two sets of tensioning components 5 to increase the contact area between the transmission belt 4 and the drive wheel 33, thereby increasing friction. When the transmission belt 4 is stretched due to prolonged use, the tension of the adjusting spring 54 is used to keep the transmission belt 4 tightly against the drive wheel 33 to prevent slippage. The tension sensor 55 is used to detect the tension of the transmission belt 4 in real time. When the transmission belt 4 stretches to a certain length and the tension of the adjusting spring 54 cannot compensate, the tension sensor 55 detects that the tension is lower than the set value and sends a signal to the controller 6 to remind the operator to perform maintenance.

[0034] In summary, this device features convenient tension adjustment, ease of use and maintenance.

[0035] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
