Description

Technical Field

[0001] The invention relates to the technical field of gypsum board manufacturing equipment, and in particular to a gypsum board molding edge compounding device and a control method. Background Art

[0002] In the prior art, a conveyor belt conveyor is mostly used to transport wet gypsum boards. During the transmission process, the conveyor belt often drifts or deviates irregularly, causing the wet gypsum boards to deviate from their original positions, which can easily lead to failure of the edge correctors used to correct the chamfers of the gypsum boards on both sides of the conveyor belt conveyor.

[0003] In the prior art, in order to make the position of the multiplexer adaptively adjusted according to the offset of the gypsum board, an ultrasonic sensor is usually set upstream to detect the belt offset distance, which is then transmitted to the multiplexer through a main control machine to form feedback adjustment. However, the thickness of the transmission belt is mostly only 1-5mm, and the reflection effect of the ultrasonic wave on its side is limited, which can easily cause detection errors.

[0004] Therefore, it is necessary to provide a gypsum board forming edge compounding device and control method to solve the problem that the edge compounding device in the existing device cannot automatically adjust according to the transmission status of the transmission belt in time, and the signal reflection surface is narrow when using ultrasound to detect the offset distance of the transmission belt, resulting in inaccurate signal feedback.

[0010] The second working condition: the transmission belt deviates and contacts the contact roller. The pressure of the transmission belt on the contact roller is applied to the reflective plate through the connecting rod, causing the reflective plate to move in the same direction and distance as the transmission belt.

[0011] Furthermore, magnetic sheets are respectively provided on the opposite side walls of the reflector and the connecting rod base, and the like magnetic poles of the magnetic sheets are opposite to each other, so that the repulsive force generated between the reflector and the connecting rod base is balanced with the tension of the rope body on the reflector, and the reflector remains stationary.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figure 1-Figure 4 As shown, the present invention provides a gypsum board forming edge compounding device, comprising:

[0041] A detection assembly 10 is symmetrically arranged on both sides of the transmission belt. The detection assembly 10 includes a connecting rod base 11, a connecting rod guide cylinder 111 is arranged on the connecting rod base 11, a connecting rod 112 is coaxially arranged inside the connecting rod guide cylinder 111, one end of the connecting rod 112 is provided with a contact roller 113 capable of contacting the side of the transmission belt, the contact roller 113 drives the connecting rod 112 to produce a same-direction displacement as the transmission belt deviates, the other end of the connecting rod 112 is provided with a reflecting plate 114 capable of moving with the connecting rod 112, a sensor bracket 12 is arranged on the connecting rod base 11, and an ultrasonic sensor 121 is arranged on the sensor bracket 12, so as to detect the displacement distance of the transmission belt to either side thereof by measuring and feeding back the displacement of the reflecting plate 114;

[0042] The adjustment component 20 is arranged downstream of the detection component 10. The adjustment component 20 includes a ball screw 21 arranged in the center above the transmission belt. Both ends of the ball screw 21 are connected to the compound edge plates 23 arranged on both sides of the gypsum board being transmitted through movable plates 22. The movable plate 22 is driven by a linear stepping motor, so that the relative distance between the compound edge plates 23 is adjusted by adjusting the position of the movable plate 22 on the ball screw 21.

[0043] Among them, fixed pulleys 13 are provided on both sides of the connecting rod guide cylinder 111 on the connecting rod base 11, and a rope body 131 is wound on the fixed pulley 13. One end of the rope body 131 is connected to the reflective plate 114, and the other end of the rope body 131 is connected to the balance block 132. When the transmission belt is not in contact with the contact roller 113, the reflective plate 114 can maintain abutment with the end face of the connecting rod guide cylinder 111 under the action of the gravity of the balance block 132.

[0044] The present invention aims to detect the running condition of the transmission belt through the detection component 10, and feed back the distance offset signal of the transmission belt to the adjustment component 20 through the industrial computer, so that it drives the movable plate 22 on the ball screw 21 through the provided linear stepping motor to adjust the relative distance between the compound edge plates 23, thereby making early warning adjustments to the offset of the gypsum board driven by the transmission belt. More importantly, the present invention uses a reflection plate 114 that moves with the offset of the transmission belt as a sound wave signal reflection surface. By increasing the sound wave reflection surface, the problem of small and poor reflected signals by the ultrasonic sensor 121 after sending a signal to the narrower side of the transmission belt is avoided, thereby improving the accuracy of the transmission belt offset distance signal measurement feedback.

[0045] More specifically, when the transmission belt is transmitting normally, its side does not contact the contact roller 113, and the detection component 10 is in an initial state. In this initial state, the reflector 114 is pulled down by the balance block 132 through the rope body 131 so that the reflector 114 abuts against the end face of the connecting rod guide cylinder 111. At this time, the reflector 114 is pulled by the rope body 131 and abuts against the end face of the connecting rod guide cylinder 111; when the transmission belt deviates to one side, its side will press the contact roller 113 to put the detection component 10 into a working state. In this working state, since the side of the transmission belt will continuously apply pressure to the contact roller 113, the contact roller 113 drives the connecting rod 112 to slide in the connecting rod guide cylinder 111. At the same time, the connecting rod 112 drives the reflector 114 at its end. 4 moves in the direction close to the ultrasonic sensor 121, and the ultrasonic sensor 121 feeds back the measured position deviation signal of the reflector 114 to the industrial computer, and then the industrial computer transmits the signal to the adjustment component 20 to control the linear stepping motor to adjust the position of the movable plate 22, so that the relative distance between the compound edge plates 23 is adjusted, so as to ensure that the compound edge plates 23 are always in a better position for compounding the gypsum board; and when the transmission belt returns to the normal transmission position, since the contact roller 113 loses the pressure on the side of the transmission belt, the balance block 132 uses its own weight to pull the reflector 114 through the rope body 131 to reset to the initial state of contact with the end face of the connecting rod guide cylinder 111, so as to prepare for the detection feedback when the transmission belt deviates next time.

[0046] In the above embodiment, if the gravity of the balance block 132 is large enough, it is easy to cause the detection of the detection component 10 to lose its function, that is, when the side of the transmission belt contacts the contact roller 113, its pressure is difficult to overcome the gravity of the balance block 132, and the contact roller 113 cannot be moved to cause the side of the transmission belt to curl, thereby failing to cause the reflector 114 to produce a corresponding displacement, and the corresponding displacement change signal cannot be fed back.

[0047] To solve the above problems, please continue to refer to Figure 2-Figure 3 In a preferred embodiment provided by the present invention based on the above embodiment, an elastic member 14 fixedly connected to the reflective plate 114 is provided on the connecting rod base 11; wherein at least two elastic members 14 are centrally symmetrically provided about the connecting rod 112, so that the reflective plate 114 has the following two working conditions according to whether the transmission belt contacts the contact roller 113:

[0048] First working condition: the transmission belt is transmitting normally without deviation, and it is separated from the contact roller 113. The tension of the rope body 131 on the reflective plate 114 is balanced with the reverse elastic force of the elastic member 14, and the reflective plate 114 is stationary.

[0049] The second working condition: the transmission belt deviates and contacts the contact roller 113. The pressure of the transmission belt on the contact roller 113 is applied to the reflection plate 114 through the connecting rod 112, so that the reflection plate 114 is displaced in the same direction and distance as the transmission belt.

[0050] In this embodiment, by setting the elastic member 14, the detection component 10, in the initial state, uses the elastic potential energy generated when the elastic member 14 is compressed to offset the tension on the rope body 131 caused by the gravity of the balance block 132, so that the resultant force on the reflective plate 114 is 0, and the side of the transmission belt can more easily press against the contact roller 113 to cause the reflective plate 114 to produce a displacement consistent with the offset distance of the transmission belt, thereby ensuring the detection effectiveness of the detection component 10.

[0051] In order to solve the same problem mentioned above, in another embodiment provided by the present invention based on the above embodiment, magnetic sheets 15 are respectively provided on the opposite side walls of the reflection plate 114 and the connecting rod base 11, and the like magnetic poles of the magnetic sheets 15 are opposite to each other, so that the repulsive force generated between the reflection plate 114 and the connecting rod base 11 is balanced with the pulling force of the rope body 131 on the reflection plate 114, and the reflection plate 114 maintains a stationary state.

[0052] In this embodiment, the elastic member 14 is replaced by a magnetic sheet 15 with like magnetic poles arranged opposite to each other, so that when the detection component 10 is in the initial state, the repulsive force between the magnetic sheets 15 is used to offset the pulling force on the rope body 131 caused by the gravity of the balance block 132, so that the resultant force acting on the reflective plate 114 is 0. In addition to playing the same role as the elastic member 14, the magnetic sheet 15 in this embodiment is superior to the elastic member 14 in terms of performance because it is simple to set up and is not easily damaged.

[0053] In the above embodiment, the setting of the connecting rod 112 can only detect the lateral displacement of the transmission belt through its own linear movement. However, in actual use, the transmission belt will often be diagonally offset. That is, when the transmission belt is diagonally offset, in addition to the positive pressure or thrust on the connecting rod 112, it will also generate shear force on it, so that the connecting rod 112 has a tendency to move along the conveying direction of the transmission belt.

[0054] In order to solve the above problems, Figure 7-Figure 8 As shown, in another embodiment provided by the present invention, the connecting rod 112 includes a connecting rod 112a and a connecting rod 112b which are arranged in sections, one end of the connecting rod 112a and the connecting rod 112b are arranged oppositely inside the connecting rod guide cylinder 111, one end of the connecting rod 112a is connected to the contact roller 113, and one end of the connecting rod 112b is connected to the reflective plate 114;

[0055] The inner cavity of the connecting rod guide cylinder 111 is expanded outward near the connecting rod 112a to form a movable portion 115 for accommodating the swing of the connecting rod 112a.

[0056] In order to reduce the friction between the ends of the connecting rod 112a and the connecting rod 2 112b, please continue to refer to Figure 8 A top block 16 is provided inside the connecting rod guide cylinder 111 between the connecting rod 1 112a and the connecting rod 2 112b. The end of the top block 16 close to the connecting rod 1 112a bulges outward to form a dome 161. The end of the connecting rod 112a is provided with a recess 116 that over-fits with the dome 161, so that the connecting rod 112a can push the top block 16 while swinging.

[0057] In this embodiment, by means of the segmented connecting rod 112 and the top block 16 arranged in coordination therewith, when the transmission belt is obliquely offset to generate shear force thereon, the connecting rod 112a can be deflected accordingly in the movable portion 115 of the connecting rod guide cylinder 111, and the over-fit between the dome 161 on the top block 16 and the recess 116 at the end of the connecting rod 1 112a is utilized to reduce the wear between the ends of the connecting rod 1 112a and the connecting rod 2 112b, thereby making the rotation of the connecting rod 112a smoother.

[0058] In order to increase the flexibility of the connecting rod 112a in the connecting rod guide tube 111, Figure 9-11 As shown, in another embodiment provided by the present invention, the end of the connecting rod 112a is contracted inward to form a wedge-shaped end 162 with a rectangular end surface, so that the connecting rod 112a can swing in the connecting rod guide cylinder 111.

[0059] In this embodiment, by setting the wedge-shaped end 162, the connecting rod 112a can swing a certain angle in the connecting rod guide tube 111. Since its contact surface with the end surface of the connecting rod 112b is rectangular and the contact area is small, the wear of the end surface of the connecting rod 112b is reduced to a certain extent, and the pushing effect of the connecting rod 112a on the connecting rod 112b is not affected, thereby ensuring the detection accuracy of the detection component 10.

[0060] In order to calibrate the position of the reflector 114 by adjusting the initial distance between the reflector 114 and the ultrasonic sensor 121, please continue to refer to FIG. Figure 7-Figure 8 A draw rod 117 is provided at the end of the second connecting rod 112b and is connected to the top block 16. The draw rod 117 can be fixed at any position after being drawn out, so that the initial distance between the reflector 114 and the ultrasonic sensor 121 can be adjusted by the draw rod 117.

[0061] In order to form a mechanical linkage between the detection component 10 and the adjustment component 20, as shown in FIG. Figure 12-13 As shown, in another embodiment provided by the present invention, the compound edge plate 23 is rotatably connected to the bottom of the movable plate 22, so that the compound edge plate 23 can automatically adjust its position according to the offset of the side of the gypsum board.

[0062] Furthermore, the side wall of the compound edge plate 23 is connected to the end of the connecting rod 112 through the hinge rod 24, so that the compound edge plate 23 can rotate at the same angle as the connecting rod 112a swings.

[0063] In this embodiment, by setting the hinged rod 24, the compound edge plate 23 can be self-rotated through the offset of the gypsum board, so that the compound edge plate 23 always has a compounding effect on the vertical edge of the gypsum board along the conveying direction of the gypsum board; and when the connecting rod 112a swings, the hinged rod 24 can drive the compound edge plate 23 to produce a deflection at the same angle, thereby adapting to the position of the gypsum board at this time without affecting its compounding effect on the vertical edge of the gypsum board.

[0064] The control method for the gypsum board forming and edge compounding device provided in any of the above embodiments of the present invention comprises the following steps:

[0065] S100, detecting the transmission state of the transmission belt through the detection component 10, and adjusting the angle of the corresponding compound edge plate 23 in real time through the mechanically linked hinge rod 24 when the transmission belt is diagonally offset, and performing step S200 when the transmission belt is laterally offset;

[0066] S200 , input the detected displacement change signal to the industrial computer, and the industrial computer outputs the signal to feedback to the adjustment component 20 , so as to adjust the relative distance between the compound edge plates 23 .

[0067] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
