Description

Technical Field

[0001] The present invention relates to the technical field of gypsum board production, and specifically relates to a portable and precise adjustment device for a paper-faced gypsum board sensor. Background Art

[0002] In the process of cutting the edge band of gypsum boards during gypsum board production, it is necessary to detect the size of the gap between two flat gypsum boards. The sensors for this detection are usually fixedly installed directly above this gap, and the size of the gap is detected by the sensors emitting signals to the gap.

[0003] Traditional sensor installations usually use bolts to fixedly install the sensors on the brackets. Although this setting is simple and fast, it is more troublesome when adjustment is needed.

[0004] When the production line stops or an unexpected situation occurs and the position of the sensor needs to be adjusted, the traditional installation method requires removing the bolts and then manually adjusting until the sensing signal of the sensor is directly above the gap to work properly. The accuracy of manual adjustment cannot be guaranteed, and it is necessary to test back and forth, which is more troublesome and inaccurate. Summary of the Invention

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1 to 5 shown, the present invention provides a portable and precise adjustment device for a paper-faced gypsum board sensor, including a base platform 1, which is arranged above the gap between two gypsum boards.

[0034] A spacing sensor 2 is arranged on the base platform 1 and is located directly above the gap between two gypsum boards. The spacing sensor 2 detects the size of the gap by emitting sensor light onto the gap between the two gypsum boards.

[0035] A moving component 3 is arranged on the base platform 1. The moving component 3 is connected to the spacing sensor 2, and the moving component 3 can drive the spacing sensor 2 to move in a direction perpendicular to the gap between the gypsum boards.

[0036] This device uses the moving component 3 to drive the spacing sensor 2 to move, rather than directly adjusting its position by manually contacting the spacing sensor 2. Through the drive of the moving component 3, the adjustment effect can be better and the adjustment efficiency can be higher.

[0037] In this device, the spacing sensor 2 is installed above the gap between two gypsum boards through the base platform 1. (On the production line, the gypsum boards move with a single gypsum board lying flat on the production line and flowing down. There will be a gap between two adjacent gypsum boards, and the spacing sensor 2 monitors this gap.) The port of the spacing sensor 2 that emits signals faces downward, that is, towards the gap between the two gypsum boards, and the size of the gap is detected through laser signals.

[0038] As Figure 1 shown, the shape of the base platform 1 can be in the shape of a cuboid. It is fixedly installed on one side of the production line through bolts, and its overall installation position can be set along the direction perpendicular to the gap between adjacent gypsum boards. That is, the length direction of the base platform 1 is perpendicular to the vertical gap of the gypsum board. The purpose of doing this is to enable the spacing sensor 2 to have enough space to move on the base platform, so as to have space to adjust the position of the spacing sensor 2.

[0039] The moving component for adjusting the spacing sensor 2 can include screw spindles 4 arranged on both sides of the base platform 1. The screw spindles 4 are rotationally installed on the base platform 1 by means of thread engagement. The spacing sensor 2 is arranged between the two screw spindles 4, and the end of the screw spindle 4 is rotationally connected to the spacing sensor 2.

[0040] The length direction of the screw spindle 4 is the same as the length direction of the base platform 1. One end of it is arranged outside the base platform 1 and connected with a rotating head for easy grasping, and the other end is rotationally connected to the spacing sensor 2. The advantage of such a setting is that when the screw spindle 4 is turned, its end rotates on the spacing sensor 2, and the screw spindle 4 as a whole moves along its own axis direction on the base platform, thereby pushing the spacing sensor 2 to move on the base platform.

[0041] However, this kind of operation requires the operator to grasp the screw spindles 4 on both sides and turn them simultaneously. If only one side of the screw spindle 4 is turned, the spacing sensor 2 cannot be pushed to move. Therefore, the screw spindles 4 on both sides need to maintain synchronous movement so that the spacing sensor 2 can achieve the purpose of moving on the base platform.

[0042] Moreover, as shown in the figure, if the spacing sensor 2 is directly connected to the screw spindle in this device, the connection position is not easy to handle and is not stable enough during specific implementation. Therefore, a connecting slider is provided. A connecting slider 5 is arranged on the bottom surface of the base platform 1. The connecting slider 5 is connected to the screw spindle 4. The middle part of the connecting slider 5 is recessed inward to form a loading cavity 6, and the spacing sensor 2 is fixedly installed in the loading cavity 6.

[0043] A long groove 7 is opened in the middle of the base platform 1. The extending direction of the long groove 7 is perpendicular to the gap of the gypsum board, and the loading cavity 6 is arranged in the long groove 7.

[0044] By arranging the spacing sensor 2 inside the loading cavity 6 of the connecting slider, the connecting slider 5 is slidably connected to the base table 1. The connecting slider 5 is pushed to move by the screw rod 4, thereby driving the spacing sensor 2 to move.

[0045] However, the method of using two screw rods 4 is rather troublesome in actual operation. It would be more convenient if only one side of the screw rod 4 needs to be turned to drive the spacing sensor 2 to move while stably installing the spacing sensor 2.

[0046] Therefore, further, the device is provided with an independent screw rod 19. In addition to the solution that the moving component 3 includes two screw rods 4, it can also include an independent screw rod 19. The two ends of the independent screw rod 19 are helically connected to the base table 1 by means of thread engagement. The rod body of the independent screw rod 19 penetrates through the connecting slider 5 and is rotatably connected to the connecting slider 5. Circular retaining plates 20 are fixedly arranged on both sides of the connecting slider 5 on the independent screw rod 19, and the circular retaining plates 20 are in contact with the connecting slider 5.

[0047] This setting is to arrange the independent screw rod 19 to penetrate through the connecting slider 5 (the part of the independent screw rod 19 penetrating through the connecting slider 5 does not block the position of the transmitting head of the spacing sensor 2 to prevent blocking the signal transmitted by the spacing sensor 2). Circular retaining plates 20 are arranged on the independent screw rod 19. The independent screw rod 19 penetrates through and is movably connected to the connecting slider 5. At this time, circular retaining plates 20 are fixedly arranged on both sides of the connecting slider 5 on the independent screw rod 19, so that when the independent screw rod 19 slides on the base table 1, the connecting slider 5 can be pushed to move through the circular retaining plates 20.

[0048] This setting only needs to turn the end of the independent screw rod 19 on one side to make the connecting slider 5 move, which is more convenient and faster to operate.

[0049] In addition, a slideway 8 is arranged on the surface of the base table 1 with a long groove 7, and a detailed slider 9 is arranged on the connecting part. The connecting slider 5 is slidably connected to the base table 1 by embedding the detailed slider 9 into the slideway 8. The connection between the detailed slider 9 and the slideway can make the movement of the connecting slider 5 on the base table 1 more stable.

[0050] However, for the spacing sensor 2, during its specific operation, it cannot shake significantly, otherwise it will affect the detection effect, and there are multiple moving clearances in the connection of the spacing sensor 2 to the base table 1.

[0051] Such as the moving clearance between the detailed slider 9 and the slideway 8. If this moving clearance is not eliminated after the position of the spacing sensor 2 is stabilized, during the specific implementation, the spacing sensor 2 will be shaken due to the start of the production line, thus affecting the detection effect.

[0052] Therefore, asFigure 3 As shown, the device is also provided with a square hole assembly on the base 1 for fixing the position of the loading chamber 6. The square hole assembly includes a transverse through hole 10, a sliding block 11 and a fastening screw 12. The transverse through hole 10 is opened on a side of the base 1 away from the connecting slider 5. The extension direction of the transverse through hole 10 is the same as the extension direction of the long groove 7.

[0053] The sliding block 11 is slidably connected in the transverse through hole 10, and a threaded through hole 13 is opened in the middle of the transverse through hole 10. One end of the fastening screw 12 is fixedly connected to the bottom surface of the loading chamber 6, and the other end extends to the outside of the base 1 through the threaded through hole 13, and the fastening screw 12 and the threaded through hole 13 are spirally connected by threaded engagement.

[0054] By connecting the fastening screw 12 with the loading chamber 6, after the connecting slider 5 drives the spacing sensor 2 to adjust its position, the loading chamber 6 can be lifted up (through the spiral connection between the fastening screw 12 and the threaded through hole 13), so that the detail slider 9 can abut against the top of the slide 8, and the two surfaces are in contact, thereby eliminating the internal movable gap (this movable gap is a gap to facilitate the detail slider 9 to move smoothly in the slide 8).

[0055] On the other hand, since the connecting slider 5 needs to slide on the base 1, the threaded through hole 13 connected to the fastening screw 12 is also slidably connected to the base 1 through the sliding block 11. Therefore, there is a movable gap between the sliding block 11 and the base 1. Therefore, the device further arranges a tightening screw 14 to eliminate the movable gap here, so that the shaking of the entire device during use can be reduced to a minimum, and it can be more stable after installation.

[0056] like Figure 4 As shown, one end of the tightening screw 12 located outside the base 1 is connected to a tightening screw 14, one end of the tightening screw 14 is connected to the tightening screw 12 by threaded engagement, and the other end is suspended above the base 1. The tightening screw 14 is spirally connected to the tightening screw 12 to tighten the end thereof against the side of the base 1 having the transverse through hole 10 to eliminate the movable gap between the sliding block 11 and the transverse through hole 10.

[0057] The top screw 14 is connected to the fastening screw 12. After the fastening screw 12 reaches the position, the end of the top screw 14 is pressed against the surface of the base 1, so that the fastening screw 12 drives the sliding block to lift up, thereby eliminating the gap between it and the transverse through hole 10.

[0058] However, it is rather troublesome to screw the two tightening lead screws 14, so a synchronization mechanism 16 is also provided. A base plate 15 is provided at the end of the fastening lead screw 12. Two tightening lead screws 14 are respectively provided on the base plate 15. The tightening lead screws 14 are located on both sides of the fastening lead screw 12. A synchronization mechanism 16 is also provided on the base plate 15 for connecting the two tightening lead screws 14 and driving the two tightening lead screws 14 to rotate synchronously.

[0059] The synchronization mechanism 16 includes a rotating gear 17 located between the two tightening lead screws 14 and a flexible rubber tooth ring 18 meshed with the rotating gear 17. Teeth are provided on the inner side of the flexible rubber tooth ring 18 and meshed with the rotating gear 17 and the ends of the tightening lead screws 14. The teeth of the flexible rubber tooth ring 18 can be longitudinally deformed, and the flexible rubber teeth 18 can drive the tightening lead screws 14 to move longitudinally on the base plate 15.

[0060] The flexible rubber tooth ring 18 is required to have a deformable effect. Since the tightening lead screw 14 needs to not only rotate but also move longitudinally (the characteristic of screw connection) on the base plate, when the tightening lead screw 14 moves longitudinally, the external components driving the tightening lead screw 14 to rotate cannot be aligned for limiting, and misalignment will generate internal stress and hinder its longitudinal movement. Therefore, the component connected to the tightening lead screw 14 here is set as the flexible rubber tooth ring 18. When the tightening lead screw 14 moves up and down, it can drive the teeth of the flexible rubber tooth ring 18 to deform, and can drive the teeth meshed with the tightening lead screw 14 to move slightly up or down synchronously, so as to realize the tightening and loosening of the tightening lead screw 14.

[0061] Since the function of the tightening lead screw 14 is to press the end thereof against the surface of the base table, the height of its lifting (i.e., the moving stroke) can be very small, even within 1 silk - 10 silk. It is precisely due to this characteristic that it is possible for the tightening lead screw 14 to drive the flexible rubber tooth ring 18 to deform slightly to press against the base table 1.

[0062] A circular groove is formed on the side surface of the connecting slider 5, and the circular retaining piece 20 is embedded in the circular groove to be connected with the connecting slider 5.

[0063] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
