[0001] The invention relates to the technical field of fixing equipment, in particular to an adhesive tape roll bundling device for 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 tie the head end of the tape with a binding belt or wire before rolling it to prevent the front end from unrolling for production and maintenance needs. Since the conveyor belt is mainly made of rubber and has high elasticity and thickness, it is time-consuming and laborious for workers to tie it, and it is not conducive to improving work efficiency. In summary, it is particularly necessary to provide a device that can provide convenience for workers to tie conveyor belts and improve work efficiency. Summary of the invention

[0006] Furthermore, a force-sensitive resistor is installed between the upper end of the guide groove of one of the fixing plates and the upper end of the cylinder of the first set of electric push rods, and two wiring terminals of the force-sensitive resistor are electrically connected in series between two signal input terminals of the control circuit.

After tightening the binding belt, the staff controls the third set of electric push rods through the power switch to push the pressure block downward to tighten the fixed buckle sleeved on the fixed part of the binding belt, and then fix the fixed part of the binding belt to achieve the binding and fixation of the conveyor belt. The present invention brings convenience to the staff, reduces the labor intensity of the staff, and correspondingly improves the work efficiency. Based on the above, the present invention has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 , 2As shown, a force-sensitive resistor RT is installed between the upper end of the guide groove 9 of the left fixed plate and the upper end of the cylinder of the first set of electric push rods M2, and a protective rubber pad is bonded to the upper and lower force-bearing surfaces of the force-sensitive resistor RT. The two terminals of the force-sensitive resistor are connected in series through wires between the two signal input terminals of the control circuit, the positive power input terminal of the relay K1 and one end of the resistor R1. Two sets of stretching rollers 2 and two sets of motor reduction mechanisms M are located between the inner sides of the left and right side end fixed plates 8, and the two sets of stretching rollers 2 and two sets of motor reduction mechanisms M are in a vertical structure from top to bottom. The front and rear widths of the guide blocks 11 and guide blocks A13 are slightly smaller than the width between the front and rear of the inner side of the guide groove 9 by 0.2 mm. The outer diameter of the pressing block 15 is slightly smaller than the inner diameter of the opening in the middle of the fixed shell 14 by 1 mm. The control circuit includes an adjustable resistor RP1, a relay K1, a resistor R1, and an NPN transistor Q1 connected via circuit board wiring. The positive power input terminal and the positive control power input terminal of the relay K1 are connected to one end of the adjustable resistor RP1 and one end of the resistor R1. The other end of the adjustable resistor RP1 is connected to the emitter of the NPN transistor Q1 and the negative control power input terminal of the relay K1. The collector of the NPN transistor Q1 is connected to the negative power input terminal of the relay K1. The other end of the resistor R1 is connected to the base of the NPN transistor Q1. The two terminals of the two sets of motor reduction mechanisms M are connected in opposite ways.

[0018] Figure 1 , 2 As shown, the power input terminals 1 and 2 of the power module A1 are connected to the two poles of the AC 220V power supply via wires, the power output terminals 3 and 4 of the power module A1 are connected to the power input terminals 1 and 2 of the three power switches S, S1, and S2 via wires, wherein the power output terminals 3 and 4, 5 and 6 of the two power switches S and S1 are connected to the positive and negative and negative-positive power input terminals of the two motor reduction mechanisms M, and the positive and negative and negative-positive power input terminals of the third electric push rod M1 via wires, respectively. The third power switch The first power output terminal 3 and 4 pins of switch S2 are connected to the positive and negative power input terminals of the first set of electric push rods M2 and the second set of electric push rods M2 through wires, respectively. The power output terminals 5 and 6 pins of the third power switch S2 are connected to the positive power input terminal of the power input terminal relay K1 of the control circuit and the emitter of the NPN transistor Q1 through wires, respectively. The two normally closed contact terminals of the power output terminal relay K1 of the control circuit are connected to the positive and negative power input terminals of the first set of electric push rods M2 and the second set of electric push rods M2 through wires.

[0019] Figure 1 , 2As shown in Figure 3, before using the present invention, the power input plug of the power module A1 is inserted into the power socket, so that the power module A1 is powered on and its 3 and 4 pins output 24V DC power to the power input terminals of the three power switches. When it is necessary to bundle the conveyor tape roll 18, the conveyor tape bundling belt 19 is annularly sleeved on the bundling part of the head end of the conveyor tape roll 18 (the bundling belt 19 sleeves the head end of the conveyor tape therein), and the front and rear ends of the bundling belt 19 are folded up and down together and introduced backward through the lead hole 6 and placed between the front ends of the two stretching rollers 2. After the staff turns the handle of the power switch S to the left (the 1, 2 feet and the 3, 4 feet of the power switch S are connected respectively), the positive and negative poles of the two sets of motor reduction mechanisms M are energized, and the upper set of motor reduction mechanisms M drives the upper set of stretching rollers 2 to rotate clockwise, and the lower set of motor reduction mechanisms M drives the lower set of stretching rollers 2 to rotate counterclockwise. In this way, the bundling belt 19 located between the two sets of stretching rollers 2 will be pulled backward by the two stretching rollers 2 rotating in the opposite direction. Due to the pulling reverse force, the front end of the limit plate 5 of the equipment will contact the front side end of the conveyor tape 18, which is convenient for subsequent operations. After the two sets of stretching rollers 2 tighten the ends of the binding belt 19, turn off the power switch S (during the movement of the binding belt, the staff will manually guide the binding belt into the fixed shell 14 after the binding belt 19 is located at the rear end of the stretching roller 2). Then the staff will put a fixing buckle 3 on the outside of the binding belt 19 and push the fixing buckle 3 to be located in the middle of the fixed shell 14. Then the staff will turn the handle of the power switch S1 to the left (the 1st and 2nd feet and the 3rd and 4th feet of the power switch S1 are connected respectively), and the positive and negative poles of the third set of electric push rods M1 will be energized. The active column of the third set of electric push rods M1 will push the pressure plate 15 downward to press the fixing buckle 3 at the fixed part of the binding belt, and then fix the fixed part of the binding belt 19, so as to achieve the bundling and fixation of the conveyor belt 18 (turn off the power switch S1 after pressing the binding belt). After pressing, the staff member turns the handle of the power switch S1 to the right (the 1st and 2nd pins and the 5th and 6th pins of the power switch S1 are connected respectively), and the negative and positive poles of the third set of electric push rods M1 are energized. The active column of the third set of electric push rods M1 drives the pressure plate 15 upward and no longer presses the fixing buckle 3 of the fixed part of the binding belt. The equipment can be taken out later. Subsequently, the staff member turns the handle of the power switch S2 to the right (the 1st and 2nd pins and the 5th and 6th pins of the power switch S2 are connected respectively), and the negative and positive poles of the first and second sets of electric push rods M2 are energized. The active columns of the first and second sets of electric push rods M2 push the upper set of stretching rollers 2 and the upper set of motor reduction mechanism M upward along the guide groove through the guide block 11 and the guide block A13. The spacing between the upper and lower stretching rollers 2 is pulled apart and is greater than the thickness of the binding belt and the fixing buckle. In this way, the staff member can withdraw the entire equipment backward to complete the bundling and fixing of the conveyor belt.

[0020] Figure 1 , 2As shown in Figures 3 and 4, in the present invention, before the staff ties and binds the straps each time, the staff turns the handle of the power switch S2 to the left (the 1st and 2nd feet and the 3rd and 4th feet of the power switch S2 are connected respectively), and the positive and negative poles of the first and second sets of electric push rods M2 are energized, and the movable columns of the first and second sets of electric push rods M2 drive the upper set of stretching rollers 2 and the upper set of motor reduction mechanisms M to move downward along the guide grooves through the guide blocks 11 and the guide blocks A13, and the distance between the upper and lower stretching rollers 2 is shortened and is smaller than the thickness of the straps (the power switch is turned off after they are in place, and when the two sets of stretching rollers pull the upper and lower overlapping straps backward and slip, the power switch can be turned to the left again), so that the subsequent two sets of stretching rollers can effectively pull the upper and lower overlapping straps backward. In the present invention, when the spacing between the two sets of stretching rollers 2 is appropriate and the binding belt 18 is effectively pulled backward, the force acting on the force-bearing surface of the force-sensitive resistor RT by the upper part of the cylinder of the left end electric push rod is relatively small, and the voltage division of the force-sensitive resistor RT is large. In this way, the 24V power supply is divided by the adjustable resistor RP1 and the force-sensitive resistor RT, and the resistor R1 reduces the voltage and limits the current. The base voltage entering the NPN transistor Q1 is relatively low, lower than 0.7V, then the NPN transistor Q1 will not be turned on, the relay K1 will not be energized, and its control power input terminal and the normally open contact terminal will be open, and the negative and positive poles of the first and second sets of electric push rods M2 will not be energized. When the spacing between the two sets of stretching rollers 2 is too small (the spacing is small and the thickness of the binding belt is large, then the upper set of stretching rollers moves upward a relatively large distance and the force acting on the force-sensitive resistor RT is relatively large), pulling the binding belt 18 to move backward and the motor reduction mechanism M is overloaded and there is a possibility of damage, the force acting on the force-bearing surface of the force-sensitive resistor RT by the upper part of the cylinder of the left-end electric push rod is relatively large, and the force-sensitive resistor RT has a small voltage division. In this way, the 24V power supply is divided by the adjustable resistor RP1 and the force-sensitive resistor RT, and the resistor R1 reduces the voltage and limits the current. The base voltage of the NPN transistor Q1 is relatively high, higher than 0.7V, then the NPN transistor Q1 will be turned on, the relay K1 will be energized, and its control power input terminal and the normally open contact terminal will be closed. Then, the negative and positive poles of the first and second sets of electric push rods M2 will be energized to drive the upper set of stretching rollers and the motor reduction mechanism M to rise in height, thereby reducing the load of the motor reduction mechanism M. When the spacing between the two sets of stretching rollers 2 is appropriate again, and the binding belt 18 is effectively pulled backward, the force acting on the force-bearing surface of the force-sensitive resistor RT by the upper part of the cylinder of the left-end electric push rod is relatively small again, and the voltage division of the force-sensitive resistor RT is large again. In this way, the 24V power supply enters the NPN transistor Q1 base voltage after the adjustable resistor RP1 and the force-sensitive resistor RT are divided, and the resistor R1 reduces the voltage and limits the current, and then the NPN transistor Q1 will not be turned on again, and the relay K1 will lose power again, and its control power input terminal and the normally open contact terminal will be open. The first and second sets of electric push rods M2 will lose power, and will no longer drive a set of stretching rollers and the motor reduction mechanism M to rise in height, thereby ensuring that the load of the motor reduction mechanism M is not too large, and the two sets of stretching rollers can still effectively pull the binding belt backward.Through the combined effect of all the above mechanisms and circuits, the present invention brings convenience to the staff, reduces the labor intensity of the staff, and correspondingly improves the work efficiency. Figure 2 In the figure, the resistance value of resistor R1 is 47K; relay K1 is a DC24V relay; model of NPN transistor Q1 is 9013; model of adjustable resistor RP1 is 470K (adjusted to 18.3K in this embodiment). Specifically, when the production technician adjusts the resistance value of adjustable resistor RP1 to be relatively large, its partial pressure is large. Then, when the interval between the two sets of stretching rollers is relatively large and the resistance value of force-sensitive resistor RT is relatively large, NPN transistor Q1 will be turned on, that is, the interval threshold value of the present invention becomes larger, and when the resistance value of adjustable resistor RP1 is adjusted to be relatively small, its partial pressure is small. Then, when the interval between the two sets of stretching rollers is relatively small and the resistance value of force-sensitive resistor RT is relatively small, NPN transistor Q1 will be turned on, that is, the interval threshold value of the present invention becomes smaller. The specific adjustment can be adjusted in combination with actual production needs; force-sensitive resistor RT is a model RP-C18.3-LT resistive pressure sensor.
