Description

Technical Field

[0001] The invention relates to the technical field of fixing equipment, in particular to a buckle device for an adhesive belt of a belt conveyor. Background Art

[0002] Electric belt conveyor is a widely used equipment. Its main structure includes motor reduction mechanism, frame, conveyor roller and an endless conveyor belt (also called conveyor belt) connected together at the head and tail ends by buckles. When working, the motor reduction mechanism drives the conveyor roller to rotate, and then the conveyor roller drives the conveyor belt to rotate, transporting items from one workstation to another.

[0003] Manufacturers of electric belt conveyors and conveyor belts, as well as terminal manufacturers using electric belt conveyors, need to be equipped with a buttoning machine for production and maintenance needs. The two ends of a new conveyor belt or a broken conveyor belt are connected together by a connecting ring (] type) through a buttoning method to form a ring (there are two vertically distributed fixing holes at the upper and lower parts of the rear end of the connecting ring). In the prior art, when connecting the ends of the conveyor belt, the ends of the belt are generally peeled with an electric peeling machine to ensure that the height difference between the subsequent installation of the annular connecting ring and the plane of the entire belt is not large, and the belt can run smoothly (reduce vibration). Then, multiple connecting rings are installed at different intervals at the ends of the belt at multiple fixed positions (each fixed position is processed with a groove by the peeling machine) with buttons, and finally the multiple connecting rings at the ends of the belt are staggered in a straight line horizontally and fixed together with screws to achieve the preparation or maintenance of the ring belt. At present, the fastening machine used for conveyor belts can only fasten one annular connecting ring at a time, so the working efficiency is relatively low. It is particularly necessary to provide a device that can fasten and connect all multiple connecting rings at one time. Summary of the invention

[0004] In order to overcome the problem that the existing conveyor belt is connected with multiple connecting rings at both ends, the adopted buttoning machine can only button and fix one connecting ring at a time due to structural limitations, which has the disadvantages of low work efficiency and inconvenience to the staff. The present invention provides a belt conveyor belt buttoning device which can automatically pre-press multiple buttons into place each time under the joint action of relevant mechanisms, and then press the multiple buttons into the upper and lower fixing holes of the multiple connecting rings and the corresponding installation stations of the conveyor belt for fixing, thereby bringing convenience to the staff and correspondingly improving the work efficiency.

After flattening, the outer diameter of the lower end of the nail button is smaller than the outer diameter of the processing groove); an input port 11 is arranged horizontally at the lower part of the rear side end of the frame, and the lower end height of the input port 11 is consistent with the upper end height of the lower shell 9, the power module U1 and the power switch are installed on the circuit board in the component box 12, and the component box 12 is installed at the right end of the rear front part of the frame 1.

[0019] Figure 1 , 2As shown in Figures 3 and 4, the number of the second group of multiple sets of electric push rods M1, the third group of multiple sets of electric push rods M2, and the feeding mechanisms are consistent, and are consistent with the number of the connecting rings 14 of the conveyor belt 13. In the second group of multiple sets of electric push rods M1, the third group of multiple sets of electric push rods M3, and multiple sets of feeding mechanisms 3, the spacing between every two sets of electric push rods, between every two sets of feeding mechanisms, and between every two connecting rings 14 in the fixed station of the multiple connecting rings 14 of the conveyor belt is consistent. Each set of feeding mechanisms includes a feeding tube 31 and a fixing nut 32 with an open structure at the upper and lower ends. The middle part of the outer end of the feeding tube 31 has an external thread. Each set of feeding tubes 31 is sleeved in the fixing groove 61 from bottom to top, and a fixing nut 32 is screwed into each of the upper and lower ends of the feeding tube 31 to fix the feeding tube 31 in the fixing groove 61. Each button comprises an outer plastic cylindrical shell 21 and a button body 22. The upper nail handle of the button body 22 is tightly sleeved in the shell 21. The outer diameter of the shell 21 is consistent with the inner diameter of the feed tube 31. Multiple buttons 2 are vertically placed in the feed tube 31 (the plastic shell has plasticity and can be tightly sleeved in the feed tube), and the upper part of the upper button 2 and the lower part of the lower button 2 are respectively in the same plane as the upper and lower ends of the feed tube 31. The lower ends of the movable columns of the second group of multiple sets of electric push rods are respectively welded with a top plate 10 with an outer diameter smaller than the inner diameter of the feed tube. The left and right widths and heights of the input port 11 are slightly larger than the left and right widths and heights of the conveyor belt 13. The front and rear widths of the processing groove 91 are smaller than the outer diameter of the upper nail handle of the button 2 and larger than the outer diameter of the pointed cone nail portion at the lower end of the button 2. The positive power output terminal pin 3 of the power module U1 is connected in series with the positive power input terminal pin 1 of a time switch U2 through a voltage switch D via a wire, and the negative power output terminal pin 4 of the power module U2 is connected with the negative power input terminal pin 2 of the time switch U2 via a wire.

[0020] Figure 1 , 2 As shown in Figure 3, the power input terminals 1 and 2 of the power module U1 are connected to the two poles of the AC 220V power supply through wires, the power output terminals 3 and 4 of the power module U1 are connected to the power input terminals 1 and 2 of the three power switches D4, D1, and D2 through wires, and the power output terminals 3, 4 and 5, 6 of the three power switches D4, D1, and D2 are connected to the positive and negative and negative and positive power input terminals of the three sets of electric push rods M1, M2, and M3 through wires. The 3 and 4 pins of the time-controlled switch U2 are connected to the positive and negative power inputs of multiple sets of electric push rods M1 through wires. There is an opening at the lower part of the left end of a feeding tube 31 at the left end, and a photoelectric switch U3 is horizontally installed at the outer end of the opening. The detection head of the photoelectric switch U3 faces the inside of the feeding tube 31, and the power input terminals 1 and 2 of the photoelectric switch U3 and the power output terminals 3 and 4 of the power module U1 are respectively connected through wires, and the positive power output terminal 3 and the negative power input terminal 2 of the photoelectric switch U3 are respectively connected to the power input terminals of the buzzer B (24V buzzer) through wires.

[0021] Figure 1 、 2As shown in Figure 3, after the 220V AC power enters the power input end of the power module U1, the power output ends 3 and 4 of the power module U1 output a stable DC 24V power to the power input ends of the four power switches. When the present invention is used, the front and rear ends of the tape 13 are first peeled with an electric peeling machine to ensure that the height difference between the subsequent installation of the annular connecting ring 14 and the plane of the entire tape 13 is not large, and the tape 13 can run smoothly (reduce vibration), and then at the fixed positions of multiple connecting rings 14 distributed at a distance at both ends of the tape (each fixed position is processed with a groove by the peeling machine), according to conventional procedures, the opening parts of multiple metal connecting rings 14 (the upper and lower parts of the rear end of the "]"-shaped connecting ring can be pressed down and the spacing is close, so it can be initially fixed at the corresponding parts) are respectively initially pressed on the upper and lower parts of multiple corresponding installation stations of the conveyor tape 9 (without large external force, the connecting ring will not move). Next, the conveyor tape is sent forward from the input port 11 and placed on the lower end of the second group of multiple electric push rods M1 (the upper parts of the multiple connecting rings are respectively located at the vertical parts of the lower ends of the feeding pipes of the multiple feeding mechanisms, and the lower ends of the connecting rings are located at the upper ends of the processing grooves). Then the staff turns on the power switch D. After the time switch U2 is energized, it will output a constant 3-second power supply to the positive and negative power input ends of the second group of multiple electric push rods M1. As a result, the movable column of the second group of multiple electric push rods M1 moves downward into the upper end of the feeding pipe of the multiple feeding mechanisms, and a nail button 2 at the lower end of the feeding pipe of the multiple feeding mechanisms is completely pressed out of the lower end of the feeding pipe through the top plate 10. Outside (then turn off the power switch D), and the lower ends of the shells of the multiple buttons are just located in the fixed holes of the fixed stations of the multiple connecting rings; then, the staff turns the handle of the power switch D1 (all the four power switch handles are located outside the four openings at the front end of the component box) to the right (pins 1 and 2 are connected with pins 5 and 6 respectively), and the negative and positive power input ends of the first group of multiple sets of electric push rods M2 are energized, and their active columns drive the connecting plates and multiple sets of feeding mechanisms to move to the rear end. When they move to the rear stop point of the active columns of the first group of multiple sets of electric push rods M2, the multiple sets of feeding mechanisms are located at the rear ends of the multiple connecting rings, and the lower ends of the pressure plates of the third group of multiple sets of motor reduction mechanisms M3 are respectively located at the upper ends of the multiple buttons. Next, the staff member turns the handle of the power switch D2 to the left (pins 1 and 2 are connected to pins 3 and 4 respectively), and the positive and negative power input terminals of the third group of multiple sets of electric push rods M3 are energized, and their movable columns push the multiple pressure plates 8 to move downward to press the multiple nail buttons 2 into the fixing holes at the upper and lower ends of the multiple connecting rings 14 through the pointed cone part at the lower end, and press them into the conveyor belt (turn off the power switch D2 after they are in place). During the pressing process, the upper end of the lower shell will support the lower ends of the multiple nail buttons, and the lower ends of the multiple nail buttons will be pressed flat and the outer diameter will be larger than the outer diameter of the fixing hole of the connecting ring (the outer diameter of the upper end of the nail button is also larger than the outer diameter of the fixing hole). In this way, the multiple connecting rings can be effectively fixed on the conveyor belt.After pressing in, the staff member turns the handle of the power switch D2 to the right (1, 2 feet and 5, 6 feet are connected respectively), and the positive and negative power input ends of the third group of multiple electric push rods M3 are energized, and its movable column drives multiple pressing plates 8 to move upward, and the pressing plates 8 at the bottom of the conveying belt are spaced apart. In this way, the staff member can pull the conveying belt out to the rear outer end through the input port 11, and then press in multiple connecting rings at the other end of the conveying belt. Before the next use, the staff member turns the handle of the power switch D1 to the left (1, 2 feet and 3, 4 feet are connected respectively), and the positive and negative power input ends of the first group of multiple electric push rods M2 are energized, and its movable column drives the connecting plate and multiple feeding mechanisms to move to the front end. When the movable column of the first group of multiple electric push rods M2 moves to the front stop point, the multiple feeding mechanisms are again located at the upper end of the processing groove 91, and the pressing plate of the third group of multiple motor reduction mechanisms M3 is located at the front end of the processing groove 91, ready for the subsequent pressing work.

[0022] Figure 1 , 2As shown in Figure 3, in the present invention, when there are more than three nail buttons in the feeding tube, the nail buttons will block the infrared light beam emitted by the photoelectric switch U3 transmitter, and the 3rd pin of the photoelectric switch U3 does not output a high level and the buzzer B does not sound, which means that the number of nail buttons does not need to be added temporarily; when there are less than three nail buttons in the feeding tube, the infrared light beam emitted by the photoelectric switch U3 transmitter is no longer blocked by the nail buttons (the outer diameter of the active column of the electric push rod M1 is smaller than the outer diameter of the nail button, so it will not block the infrared light beam emitted by the photoelectric switch U3), and the 3rd pin of the photoelectric switch U3 outputs a high level and enters the positive power input terminal of the buzzer B, so the buzzer B is energized and sounds, which means that the number of nail buttons is small and needs to be added. In this way, the present invention can ensure that the number of nail buttons is sufficient, and prevent the adverse effects on the fixing work caused by the lack of nail buttons during processing and when the conveying tape is in place and then replenishing. Each time the power switch D of the present invention is turned on, a corresponding nail button in the feeding mechanism is located at the lower end of the feeding tube. When all the nail buttons in the feeding tube are used up, the staff can turn the handle of the power switch D4 to the right (1, 2 feet and 5, 6 feet are connected respectively), and the second group of multiple sets of electric push rods M1 positive and negative power input ends are energized and its movable column drives the top plate to move upward to the stop point and stop (with a distance from the upper end of the feeding tube). Then the staff can press multiple nail buttons into multiple feeding tubes from top to bottom. After all the nail buttons are pressed in, the staff can turn the handle of the power switch D4 to the left (1, 2 feet and 3, 4 feet are connected respectively), and the second group of multiple sets of electric push rods M1 positive and negative power input ends are energized and its movable column drives the top plate to move downward, and the lower end of the top plate just contacts the upper part of a nail button in the upper end of the feeding tube, and then the power switch is turned off to prepare for the next use. The present invention brings convenience to the staff, reduces the labor intensity of the staff, and correspondingly improves the work efficiency. The time control switch U2 is a fully automatic microcomputer time control switch product of model KG316T. The microcomputer time control switch itself has a display screen, as well as seven buttons: cancel / restore, time adjustment, minute adjustment, week adjustment, automatic / manual, timing, and clock. It also has two power input terminals, pins 1 and 2, and two power output terminals, pins 3 and 4. The user can press the seven buttons respectively to set the interval time for the power output of the two power output terminals and the time for each power output. The photoelectric switch U3 is a finished product of a PNP infrared reflective photoelectric switch of model E3K100-10, with an operating voltage of DC 24V. It has three connecting wires, two of which are power input wires at pins 1 and 2, and the other pin 3 is a signal output wire. The photoelectric switch has a detection head. When working, the transmitter of the detection head will emit an infrared beam. When the infrared beam emitted by the detection head is blocked by an object within a maximum range of 10 cm and is received by the receiving head parallel to the detection head, the signal output line pin 3 will output a high level. When there is no object blocking it, the signal output line pin 3 will not output a high level. The rear end of the photoelectric switch housing has an adjustment knob. When the adjustment knob is adjusted to the left, the detection distance of the detection head becomes closer, and when it is adjusted to the right, the detection distance of the detection head becomes farther (the detection distance in this embodiment is 5 mm).In the present invention, after the plastic shell of the nail button is flattened, it will not enter the adhesive tape due to its soft material, and can be removed from the adhesive tape later.
