Description

Technical Field

[0001] The utility model relates to the technical field of chamfering of wedge-shaped gypsum boards, in particular to a tightness adjustment device for a chamfering belt. Background Art

[0002] Gypsum board production is divided into rectangular edge and wedge-shaped edge gypsum board according to its industry standards. One side of the wedge-shaped edge gypsum board has a chamfer. Currently, the industry uses chamfering belts to chamfer the gypsum board after it is formed and before it solidifies.

[0003] Since the belt itself has the property of thermal expansion and contraction, the chamfered belt will loosen up or down as the service life and seasonal temperature change. Too tight will cause the chamfered belt to deform, too loose will cause the chamfered belt to wear, both of which will reduce the service life.

[0004] At present, in the industry, if the chamfered belt becomes loose or too tight, it is necessary to stop the machine to lengthen or shorten the chamfered belt or add or remove tensioners, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of the utility model is to provide a tension adjustment device for a chamfered belt to solve the technical problem in the prior art that when the chamfered belt becomes loose or too tight, the machine needs to be stopped to lengthen or shorten the chamfered belt or add or remove tensioners, which is time-consuming and labor-intensive.

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

[0007] It includes a processor and a tensioning wheel assembly, a pressure sensor and a displacement mechanism that are fixedly connected in sequence;

[0008] The displacement mechanism is used to drive the tensioning wheel assembly close to the forming belt to loosen the chamfered belt, or drive the tensioning wheel away from the forming belt to tighten the chamfered belt;

[0009] The pressure sensor is arranged between the displacement mechanism and the tensioning wheel assembly to monitor the tension of the chamfered belt in real time;

[0010] The processor is in communication with the pressure sensor and the displacement mechanism, and is configured to receive a tensioning force signal transmitted by the pressure sensor;

[0011] When the received tensioning force value is greater than the set tensioning force value, the processor sends a relaxation signal to the displacement mechanism;

[0012] When the tensioning force monitored by the pressure sensor is less than a set value, the processor sends a tensioning signal to the displacement mechanism.

[0013] As a preferred solution of the present invention, the tensioning wheel assembly includes a tensioning wheel provided on a wheel frame and rotatably connected to the wheel frame;

[0014] The wheel frame is arranged on the outside of the chamfered belt, and the pressure sensor is fixedly installed between the wheel frame and the displacement mechanism.

[0015] As a preferred solution of the present invention, the displacement mechanism is configured as a cylinder, and the piston rod of the cylinder is fixedly connected to the pressure sensor.

[0016] As a preferred solution of the present invention, the displacement mechanism is further provided with a forward and reverse button for manually opening the displacement mechanism.

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

[0018] The tension adjustment device is a system for monitoring and adjusting the tension of the chamfered belt based on a pressure sensor, a processor and a displacement mechanism. It can monitor the tension of the chamfered belt in real time and compare it with the set value.

[0019] When the tension is too high, the displacement mechanism drives the tensioning pulley inward to loosen the chamfered belt. When the tension is too low, the displacement mechanism drives the tensioning pulley outward to tighten the chamfered belt. This not only extends the service life of the chamfered belt, but also eliminates the need to lengthen or shorten the chamfered belt or add or remove tensioning pulleys, saving time and effort.

[0025] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, the utility model provides a tension adjustment device for a chamfered belt, comprising a processor 1 and a tensioning wheel assembly, a pressure sensor 2 and a displacement mechanism 3 fixedly connected in sequence;

[0027] The displacement mechanism 3 is used to drive the tensioning wheel assembly close to the forming belt 7 to loosen the chamfered belt 4, or drive the tensioning wheel 6 away from the forming belt 7 to tighten the chamfered belt 4;

[0028] The pressure sensor 2 is arranged between the displacement mechanism 3 and the tensioning wheel assembly, and is used to monitor the tension of the chamfered belt 4 in real time;

[0029] The processor 1 is in communication with the pressure sensor 2 and the displacement mechanism 3, and is used to receive the tension signal transmitted by the pressure sensor 2 and compare the received tension value with the tension value set for the chamfer belt 4;

[0030] When the received tension value is greater than the set tension value, the processor 1 sends a relaxation signal to the displacement mechanism 3;

[0031] When the tensioning force detected by the pressure sensor 2 is less than the set value, the processor 1 sends a tensioning signal to the displacement mechanism 3 .

[0032] When using this device, it is first necessary to set a tension value or value range of the chamfered belt 4. This tension value will neither make the belt loose, causing the chamfered belt 4 to wear, nor make the chamfered belt 4 too tight, causing the chamfered belt 4 to deform.

[0033] The tension of the chamfered belt 4 is monitored in real time by pressure sensor 2. When the tension detected by pressure sensor 2 exceeds the set value, it indicates that the belt is too tight. Processor 1 sends a release signal to displacement mechanism 3, causing displacement mechanism 3 to drive tensioning pulley 6 closer to forming belt 7, thereby loosening the chamfered belt 4. This situation generally occurs in low temperature conditions, as the low temperature causes the chamfered belt 4 to shrink and tighten.

[0034] When the tension detected by pressure sensor 2 is less than the set value, indicating that chamfered belt 4 is relatively loose, processor 1 sends a tensioning signal to displacement mechanism 3, which drives tensioning pulley 6 away from forming belt 7 to tighten chamfered belt 4. This situation generally occurs under high temperature conditions, as high temperature causes chamfered belt 4 to expand and relax.

[0035] When the tension of the chamfered belt 4 returns to the set value, the pressure sensor 2 transmits the monitored signal to the processor 1, and the processor 1 sends a stop signal to the displacement mechanism 3, and the displacement mechanism 3 stops moving the tensioning wheel assembly.

[0036] In summary, the tension adjustment device is a system for monitoring and adjusting the tension of the chamfered belt 4 based on the pressure sensor 2, the processor 1 and the displacement mechanism 3; it can monitor the tension of the chamfered belt 4 in real time and compare it with the set value.

[0037] When the monitored tension value is greater than the set value, the displacement mechanism 3 drives the tensioning pulley 6 toward the forming belt 7 to loosen the chamfered belt 4. When the monitored tension value is less than the set value, the displacement mechanism 3 drives the tensioning pulley 6 away from the forming belt 7 to tighten the chamfered belt 4. This not only extends the service life of the chamfered belt 4, but also eliminates the need to lengthen or shorten the chamfered belt 4 or add or remove tensioning pulleys, saving time and effort.

[0038] Optionally, the tension wheel assembly includes a tension wheel 6 provided on the wheel frame 5 and rotatably connected to the wheel frame 5;

[0039] The wheel frame 5 is arranged outside the chamfered belt 4 , and the pressure sensor 2 is fixedly installed between the wheel frame 5 and the displacement mechanism 3 .

[0040] When the tensioning pulley 6 is moved, the displacement mechanism 3 moves the pressure sensor 2, which in turn drives the wheel frame 5 to move, and then drives the tensioning pulley 6 to move. The tensioning pulley 6 and the wheel frame 5 can be considered to be relatively stationary, and the tensioning force of the chamfered belt 4 is transmitted to the pressure sensor 2 through the wheel frame 5.

[0041] Furthermore, the displacement mechanism 3 is configured as a cylinder, and the piston rod of the cylinder is fixedly connected to the pressure sensor 2 .

[0042] The piston rod of the cylinder moves telescopically, driving the pressure sensor 2 and the tensioning wheel assembly to move synchronously, so as to achieve the purpose of tensioning or loosening the chamfering belt 4.

[0043] Furthermore, the displacement mechanism 3 is provided with a forward and reverse button for manually opening the displacement mechanism 3 , so that the staff can adjust the tension of the chamfer belt 4 on site.

[0044] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection 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 scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
