Description

Technical Field

[0001] This invention relates to printing machinery, and more specifically to a rapid tension adjustment device for a conveyor belt of an inspection machine. Background Technology

[0002] With rising labor costs for operators, many workstations are focusing on controlling inefficient work and continuously improving and innovating traditional, inefficient manual processes. In existing inspection machines, the entire machine consists of 70-90 belts of varying shapes and sizes. Because these machines operate at high speeds, the requirements for synchronization and tension are high. If belt asynchrony occurs during startup, the machine must be stopped for manual adjustment. However, the small gaps between belts mean that each adjustment requires significant time and repeated adjustments, and the machine cannot be turned on during these processes, resulting in substantial time waste. Furthermore, each adjustment requires the removal of numerous accessories unrelated to the belts, leading to significant waste of manpower and resources and impacting production schedules. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention aims to provide a rapid tension adjustment device for a conveyor belt of an inspection machine, comprising a belt support plate and a tensioning shaft. The tensioning shaft is mounted on a support base, which is mounted on the support plate body. Adjustment holes are provided on the support plates at both ends of the support base. A pair of guide plates are provided between adjacent support plates. Connecting blocks are provided on the top of the two guide plates. Guide grooves are provided on the upper part of each guide plate, and grooves are provided on one side of the lower part of each guide plate. A threaded hole is provided at the center of the connecting block, and an adjusting screw is fitted into the threaded hole. An inverted U-shaped sleeve is connected to the lower end of the adjusting screw. The width of the sleeve is greater than the width of the conveyor belt. Protrusions are provided on both sides of the upper end face of the sleeve, and the protrusions are respectively engaged in the guide grooves with a clearance fit.

[0004] Furthermore, the tops of the two guide plates are connected to the connecting block with screws for easy disassembly.

[0005] Furthermore, the width of connecting block 3 can be made into a series of sizes, which can also be adapted to conveyor belts of different widths.

[0006] A method for quickly adjusting the tension of a conveyor belt in an inspection machine includes the following steps:

[0007] 1. During the operation of the conveyor belt, first loosen the tension screws of the fixed arc seat;

[0008] 2. Then, using the above-mentioned device, the groove of the guide plate is fitted onto the tensioning shaft, and the bottom surfaces of the two sides of the inverted U-shaped sleeve rest on the steps inside the support wall panel.

[0009] 3. Rotate the adjusting screw to drive the groove of the guide plate to move up and down, thereby causing the groove to drive the tensioning shaft to move up and down. Observe whether the adjusted conveyor belt is synchronized with other belts until it is synchronized.

[0010] 4. Then tighten the screws and remove the device.

[0011] Since existing conveyor belts all have a tensioning shaft at a different position, the tensioning shaft is fixed to an arc-shaped seat, which is fixed to the steps on the inner side of the support plates on both sides of the conveyor belt. During the operation of the conveyor belt, first loosen the tensioning screws fixing the arc-shaped seat, and then use the above-mentioned device to put the groove of the guide plate onto the tensioning shaft. The two bottom surfaces of the inverted U-shaped sleeve rest on the steps on the inner side of the support wall plate. At this time, there is a gap between the conveyor belt and the inverted U-shaped sleeve in the left, right, up, and down directions, which does not affect the movement of the conveyor belt. By rotating the adjusting screw, the arc-shaped seat can be moved up and down, so the belt tension can be adjusted without stopping the machine. After the adjustment is completed, the tensioning screws can be fixed, which effectively avoids machine stoppage, reduces the complexity of personnel operation, and improves production efficiency.

[0015] like Figure 1 As shown, a quick tension adjustment device for a conveyor belt of an inspection machine includes multiple belt support plates 11, with a conveyor belt 10 installed between adjacent belt support plates 11. A tensioning shaft 9 is installed between adjacent belt support plates 11, specifically mounted on a support seat, which is mounted on the support plate 11 body. Because the conveyor belt 10 is elastic, its tension needs to be adjusted after a period of operation.

[0016] Adjustment holes 8 are provided on the support plates 11 at both ends of the support seat. Set screws are installed in the adjustment holes 8. The support seat is moved by adjusting the set screws, thereby adjusting the tension of the conveyor belt 10. However, before the present invention was proposed, the machine could only be stopped for adjustment.

[0017] refer to Figure 2A pair of guide plates 1 are provided between adjacent support plates 11, and a connecting block 3 is provided on the top of the two guide plates. The connecting block 3 connects the two guide plates into one piece. There is a gap between the outer side of the two guide plates 1 and the inner side of the support plate 11, that is, the guide plates can be inserted into or removed from the support plates 11.

[0018] Guide grooves 2 are provided on the upper part of the guide plate 1, and grooves 5 are provided on one side of the lower part of the guide plate 1.

[0019] A threaded hole is provided at the center of the connecting block 3, and an adjusting screw 7 is installed in the threaded hole. An inverted U-shaped sleeve 4 is connected to the lower end of the adjusting screw 7. The width of the sleeve 4 is greater than the width of the conveyor belt. Protrusions 6 are provided on both sides of the upper end face of the sleeve 4. The protrusions 6 are respectively inserted into the guide groove 2. The protrusions 6 and the guide groove 2 are in clearance fit. By rotating the adjusting screw 7, if the sleeve 4 is fixed, the guide plate 1 can be moved up and down.

[0020] In use, first loosen the set screw in the adjustment hole 8. After loosening the set screw, the arc seat for installing the tension shaft 9 can move up and down. The lower bottom of the sleeve 4 is supported on the step inside the support plate 11. The groove 5 is fitted into both ends of the tension shaft 9. Then rotate the adjustment screw 7. In this way, the groove 5 can pull the tension shaft 9 to move up and down slightly, so as to observe whether the conveyor belt is synchronized. After it is synchronized, the set screw in the adjustment hole 8 can be fixed. The feature of this device is that it can realize the synchronization adjustment of the conveyor belt without stopping the machine.

[0021] Furthermore, the tops of the two guide plates are connected to the connecting block 3 by screws, which facilitates disassembly and maintenance.

[0022] Furthermore, since the conveyor belt 10 has a series of widths, it would be wasteful to make the corresponding tension quick adjustment device; however, it is only necessary to make the width of the connecting block 3 into a series of sizes, which can also be adapted to conveyor belts of different widths.

[0023] A method for quickly adjusting the tension of a conveyor belt in an inspection machine includes the following steps:

[0024] 1. During the operation of the conveyor belt, first loosen the tension screws of the fixed arc seat;

[0025] 2. Then, using the above-mentioned device, the groove of the guide plate 1 is fitted onto the tensioning shaft 9, and the bottom surfaces of the two sides of the inverted U-shaped sleeve rest on the steps inside the support wall panel.

[0026] 3. Rotate the adjusting screw 7 to drive the groove of the guide plate 1 to move up and down, thereby causing the groove 5 to drive the tensioning shaft 9 to move up and down. Observe whether the adjusted conveyor belt is synchronized with other belts until it is synchronized.

[0027] 4. Then tighten the screws and remove the device.
