Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production and molding equipment, and in particular to an automatic synchronous adjustment system for a wedge-shaped edge belt of a gypsum board. Background Art

[0002] When producing boards with wedge-shaped edges on a gypsum board production line, it is necessary to install two small wedge-shaped belts on both sides of the forming belt so that the two edges of the gypsum board form wedge-shaped chamfers when the gypsum board is formed.

[0003] The forming belt of the gypsum board is an endless belt that is 200 meters long and 1.4 meters wide. Small wedge-shaped belts with a width of 0.08 meters are also annularly attached to both sides of the forming belt. When they rotate at the same time, the small wedge-shaped belts will swing, resulting in a large deviation in the front and rear position. As a result, the appearance size of the gypsum board when it is formed on the belt is unstable, and even the edge strength of the board is insufficient and cracks appear, which can easily lead to batch scrapping of products.

[0004] In the prior art, the nylon rollers that convey the small wedge-shaped belts are adjusted by an adjustable screw rod to change the conveying position of the small wedge-shaped belts, thereby achieving the purpose of manually compensating the offset distance of the small wedge-shaped belts. However, this treatment method has certain safety hazards, long processing time, high labor consumption, and cannot effectively and timely improve the molding appearance of the gypsum board. Summary of the invention

[0005] The object of the present invention is to provide an automatic synchronous adjustment system for a wedge-shaped edge belt of a gypsum board, so as to solve the problem in the prior art that the chamfering belt of the gypsum board is prone to swing when it is driven by a main belt, resulting in a large deviation in the position of the chamfering belt upstream and downstream, which leads to poor chamfering when the gypsum board is formed on the main belt.

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0007] The invention provides an automatic synchronous adjustment system for the wedge-shaped edge belt of a gypsum board, comprising: a transmission belt, both ends of which are tensioned and transmitted by active rollers for conveying gypsum boards, the active roller shaft being connected to a first frame; a wedge-shaped belt, which is sleeved on the transmission belt and drivenly transmitted therewith, and two groups of wedge-shaped belts are symmetrically arranged near the two sides of the transmission belt; driven rollers are respectively arranged at the inner and lower sides of the active rollers for tensioning the wedge-shaped belts so that the wedge-shaped belts are separated from the transmission belts below, and the driven roller shaft is connected to a second frame; wherein a wedge-shaped belt is arranged between the two driven rollers and driven by the wedge-shaped belts. The tapered rollers are in contact with each other and rotate drivenly under the tensioned wedge belts. The large diameter ends of the tapered rollers are located on the inner sides of the two sets of wedge belts. The second frame is provided with a ball screw driven by a servo motor. An adjusting frame is fixed to the movable sleeve of the ball screw. The tapered roller shaft is connected to the adjusting frame so that the tapered roller can make reciprocating linear motion along its own axis. A photoelectric induction is provided above the tapered roller to detect the relative position between the wedge belt and the tapered roller. The PLC controller controls the linkage of the servo motor by receiving the signal of the photoelectric induction.

[0008] Furthermore, the cross-section of the wedge-shaped belt is a right-angled trapezoid, the inclination angle between its hypotenuse and vertical sides is 1°-10°, the surface where its hypotenuse is located is formed as a wedge-shaped surface, and the surface where its vertical side is located is formed as a straight surface; the transmission belt and the straight surface of the wedge-shaped belt are in mutual pressure contact.

[0009] Furthermore, the conical surface of the conical roller and the wedge surface of the wedge belt fit and contact each other, and the distances from both sides of the wedge belt to the two end surfaces of the conical roller are equal, so that the mid-profile surfaces of the two overlap each other.

[0010] Furthermore, both ends of the tapered roller are provided with outwardly extending limiting edges to limit the wedge-shaped belt.

[0011] Furthermore, multiple conical rollers are provided along the transmission path of the wedge belt to jointly support the wedge belt; wherein the small diameter end of any conical roller located on the same side is axially connected to the adjustment frame, and the large diameter ends of the conical rollers are jointly axially connected to the linkage frame.

[0012] Furthermore, a straight roller is provided between adjacent conical rollers for tensioning the wedge belt; wherein the straight roller is arranged above the wedge belt, contacts its straight surface and is driven by it; an upwardly extending shaft seat is provided on the second frame, and the straight roller shaft is connected to the shaft seat.

[0013] Furthermore, a vertical mounting support plate is extended from the second frame toward the inner side thereof for mounting the inductive photoelectric device; wherein two inductive photoelectric devices are arranged on both sides of the wedge-shaped belt, and each inductive photoelectric device is equidistant from the limiting edge adjacent thereto.

[0014] Furthermore, the small diameter end of the tapered roller located in the middle is axially connected to the adjustment frame.

[0015] Furthermore, the first frame and the second frame are fixedly mounted on the shell plate, the servo motor is fixedly arranged outside the shell plate, and the output shaft of the servo motor is connected to the power input end of the ball screw.

[0016] Furthermore, the photoelectric induction senses that the displacement of the wedge belt exceeds the tolerance and sends a displacement signal to the PLC controller. After receiving the displacement signal, the PLC controls the servo motor to start and drives the tapered roller to make a linear motion through the ball screw to compensate for the displacement difference.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention senses the relative position difference between the wedge-shaped belt and the tapered roller detected by the photoelectric induction, and transmits a signal to the servo motor through the PLC controller to start when the bottom angle of the gypsum board is chamfered by the wedge-shaped belt, and further uses the linear motion converted by the ball screw to adjust the position of the tapered roller, so as to achieve the purpose of compensating the offset distance of the wedge-shaped belt; thereby, it is possible to avoid the wedge-shaped belt from swinging during the transmission process and repeatedly rubbing the edge of the roller body, and the problem of inaccurate transmission position of the wedge-shaped belt itself due to the thrust force it receives during the chamfering of the gypsum board, and avoid the problem of spending a lot of manpower on checking and adjusting the deviation of the wedge-shaped belt in actual production, thereby improving production efficiency and chamfering yield.

[0028] 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.

[0029] like Figure 1-2 As shown, the present invention provides a gypsum board wedge-shaped edge belt automatic synchronous adjustment system, comprising:

[0030] A transmission belt 10, both ends of which are tensioned and transmitted by active rollers 11 for conveying gypsum boards, and the active rollers 11 are axially connected to the first frame 12;

[0031] The wedge-shaped belt 20 is looped on the transmission belt 10 and driven by it. Two groups of wedge-shaped belts 20 are symmetrically arranged near the two sides of the transmission belt 10. Driven rollers 21 are respectively arranged on the inner and lower sides of the driving roller 11 to tension the wedge-shaped belt 20 so that the wedge-shaped belt 20 is separated from the transmission belt 10 below. The driven rollers 21 are axially connected to the second frame 22.

[0032] Among them, a conical roller 23 in contact with the wedge belt 20 is provided between the two driven rollers 21, and the conical roller 23 rotates under the tensioned wedge belt 20, and the large diameter end of the conical roller 23 is located on the opposite inner side of the two groups of wedge belts 20; a ball screw 25 driven by a servo motor 24 is provided on the second frame 22, and an adjusting frame 26 is fixedly connected to the movable sleeve 251 of the ball screw 25, and the conical roller 23 is axially connected to the adjusting frame 26 so that the conical roller 23 can make reciprocating linear motion along its own axis; a photoelectric induction 27 is provided above the conical roller 23 for detecting the relative position between the wedge belt 20 and the conical roller 23, and the PLC controller controls the linkage of the servo motor 24 by receiving the signal of the photoelectric induction 27.

[0033] The present invention provides an automatic synchronous adjustment system for the wedge-shaped edge belt of a gypsum board. When the bottom corner of the gypsum board is chamfered by the wedge-shaped belt 20, the system can detect the relative position difference between the wedge-shaped belt 20 and the conical roller 23 detected by the induction photoelectric 27, and transmit a signal to the servo motor 24 through the PLC controller to start, and further use the linear motion converted by the ball screw 25 to adjust the position of the conical roller 23 to compensate for the offset distance of the wedge-shaped belt 20, thereby preventing the wedge-shaped belt 20 from swinging during transmission and repeatedly rubbing the edge of the roller body, and the problem of inaccurate transmission position of the wedge-shaped belt 20 itself due to the thrust force during the chamfering of the gypsum board, thereby avoiding the problem of spending a lot of manpower to check and adjust the deviation of the wedge-shaped belt 20 in actual production, thereby improving production efficiency and chamfering yield.

[0034] More specifically, the cross-section of the wedge-shaped belt 20 is a right-angled trapezoid, the inclination angle between its hypotenuse and vertical sides is 1°-10°, the surface where its hypotenuse is located is formed as a wedge-shaped surface, and the surface where its vertical side is located is formed as a straight surface; the transmission belt 10 and the straight surfaces of the wedge-shaped belt 20 are pressed against each other.

[0035] In the present embodiment, it should be noted that although the wedge-shaped belt 20 can provide partial transmission support for the gypsum board, the gypsum board still mainly relies on the transmission belt 10 for transportation. Therefore, the wedge-shaped belt 20 is preferably a 2mm-5mm belt with a thinner inner side and a thicker outer side to form a wedge-shaped surface in contact with the bottom corner of the gypsum board. The thinner inner side of the wedge-shaped belt 20 can extend 3cm-5cm below the gypsum board to chamfer the bottom corner of the gypsum board with its relative inclination, thereby forming a wedge-shaped edge on the gypsum board, so as to form a groove between adjacent gypsum boards for sticking stickers and tapes and scraping gypsum putty during decoration, which can effectively prevent cracking of the joints.

[0036] In order to make the transmission of the wedge-shaped belt 20 tend to a stable state, as Figure 5 As shown, in a preferred embodiment provided by the present invention based on the above-mentioned embodiment, the conical surface of the conical roller 23 and the wedge surface of the wedge belt 20 fit and contact each other, and the distances from both sides of the wedge belt 20 to the two end surfaces of the conical roller 23 are equal, so that the mid-profile surfaces of the two overlap with each other.

[0037] In this embodiment, the tapered surface of the tapered roller 23 and the wedge surface of the wedge belt 20 are arranged to fit and contact each other, so that the wedge belt 20 is not easy to climb upward along the tapered surface of the tapered roller 23, so that the transmission of the wedge belt 20 can be stabilized on one side of the tapered roller 23, and then the ball screw 25 drives the movement of the tapered roller 23 to compensate for the displacement of the wedge belt 20. On the other hand, the tapered surface of the tapered roller 23 is conducive to preventing the thinner inner side of the wedge belt 20 from being damaged and deformed, thereby improving the overall durability of the wedge belt 20.

[0038] In order to limit the wedge belt 20 at both ends of the tapered roller 23, as shown in FIG. Figure 5 As shown, in a preferred embodiment provided by the present invention based on the above-mentioned embodiment, both ends of the conical roller 23 are provided with outwardly extending limiting edges 231 to limit the wedge belt 20.

[0039] In the above embodiment, a single conical roller 23 is provided to assist the transmission of the wedge-shaped belt 20. Since the wedge-shaped belt 20 is provided with a longer length along with the transmission belt 10, the wedge-shaped belt 20 may be too loose, which may lead to insufficient resistance between the conical roller 23 and the wedge-shaped belt 20, making it difficult for the wedge-shaped belt 20 to adjust its position along with the movement of the conical roller 23, making it difficult for the wedge-shaped belt 20 to achieve a better adjustment effect, thereby affecting the chamfering yield of the gypsum board.

[0040] To solve the above problems, please continue to refer to Figure 1-3 As shown, in a preferred embodiment provided by the present invention based on the above-mentioned embodiment, a plurality of conical rollers 23 are provided along the transmission path of the wedge-shaped belt 20 to jointly support the wedge-shaped belt 20; wherein the small diameter end of any conical roller 23 located on the same side is axially connected to the adjustment frame 26, and the large diameter end of the conical roller 23 is jointly axially connected to the linkage frame 28.

[0041] In the present embodiment, a plurality of conical rollers 23 are arranged on the transmission path of the wedge-shaped belt 20, and the large-diameter ends of the conical rollers 23 are axially connected together through the linkage frame 28, so that the wedge-shaped belt 20 can be supported together, and the wedge-shaped belt 20 is prevented from being loosened due to its excessive length, and the resistance between the conical rollers 23 and the wedge-shaped belt 20 is stabilized, so that the wedge-shaped belt 20 can be easily adjusted in time with the movement of the conical rollers 23, so that the wedge-shaped belt 20 can easily achieve a better adjustment effect, so as to improve the chamfering yield of the gypsum board.

[0042] In order to further improve the tensioning capacity of the wedge belt 20 on the conical roller 23, as Figure 6As shown, in a preferred embodiment provided by the present invention based on the above embodiment, a straight roller 29 is provided between adjacent conical rollers 23 for tensioning the wedge belt 20; wherein the straight roller 29 is provided above the wedge belt 20, contacts with its straight surface and is driven therefrom; an upwardly extending shaft seat 291 is provided on the second frame 22, and the straight roller 29 is axially connected to the shaft seat 291.

[0043] In this embodiment, by arranging a straight roller 29 between adjacent conical rollers 23, the wedge-shaped belt 20 can form an S-shaped tensioning under the transmission belt 10, so as to improve the tensioning ability of the wedge-shaped belt 20 on the conical roller 23, avoid the wedge-shaped belt 20 from being loose due to its excessive length, make the resistance between the conical roller 23 and the wedge-shaped belt 20 tend to be stable, make it easy for the wedge-shaped belt 20 to adjust its position in time with the movement of the conical roller 23, and make it easy for the wedge-shaped belt 20 to achieve a better adjustment effect, so as to improve the chamfering yield of the gypsum board.

[0044] In order to make the movement of the tapered roller 23 in the axial direction more stable, please continue to refer to Figure 1-3 As shown, in another embodiment provided by the present invention based on the above embodiment, the small diameter end of the tapered roller 23 located in the middle position is axially connected to the adjustment frame 26.

[0045] In order to support the first frame 12 and the second frame 22, please continue to refer to Figure 1 As shown, in a preferred embodiment provided by the present invention based on the above embodiments, the first frame 12 and the second frame 22 are fixedly mounted on the shell plate 30, the servo motor 24 is fixedly arranged outside the shell plate 30, and the output shaft of the servo motor 24 is connected to the power input end of the ball screw 25.

[0046] In order to calculate the offset of the wedge belt 20 by detecting the relative position difference between the wedge belt 20 and the conical roller 23, as shown in FIG. Figure 3-4 As shown, in a preferred embodiment provided by the present invention based on the above-mentioned embodiment, a vertical mounting support plate 271 extends from the second frame 22 toward the inner side thereof for mounting the sensing photoelectric 27; wherein, two sensing photoelectrics 27 are provided on both sides of the wedge-shaped belt 20, and each sensing photoelectric 27 is equidistant from the limiting edge 231 adjacent thereto.

[0047] More specifically, in order to enable the tapered roller 23 to form a linkage with the wedge belt 20 based on the displacement difference detected by the photoelectric induction 27, in a preferred embodiment provided by the present invention based on the above-mentioned embodiment, the photoelectric induction 27 senses that the displacement of the wedge belt 20 exceeds the tolerance and sends a displacement signal to the PLC controller. After receiving the displacement signal, the PLC controls the servo motor 24 to start, and drives the tapered roller 23 to make a linear motion through the ball screw 25 to compensate for the displacement difference.
