Description

Technical Field

[0001] The utility model relates to the technical field of ranging and metering facilities, in particular to an automatic metering device for the facing paper of gypsum board. Background Technique

[0002] ‌Facing paper is a paper material used to protect and cover specific items. It has various forms and applications, including but not limited to the fields of construction and packaging. In the construction field, facing paper is mainly used for paper-faced gypsum board, which is an environmentally friendly building material made of cardboard from industrial by-product gypsum and waste paper. This material recycles a large amount of industrial waste and is one of the development directions of building materials.

[0003] When using the facing paper of gypsum board, the length is generally not calculated. However, due to its large usage, according to the needs of enterprises, ranging calculations will be carried out to budget the ratio of the use of facing paper to the production of gypsum board. It is necessary to measure the usage of facing paper. Usually, a roller is installed to rub against the facing paper, and the facing paper drives the roller to rotate. An encoder is installed at one end of the roller to calculate the amount of facing paper. In this way, the friction force between the roller and the facing paper is not easy to control. If the force is too large, it is easy to damage the facing paper, and the roller also has the risk of jamming. If the friction force is too small, it cannot drive the stable rotation of the roller, resulting in inaccurate measurement. Therefore, a measurement and calculation device that is accurate in measurement and does not damage the facing paper is proposed. Content of the Utility Model

Specific embodiments

[0026] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, an automatic metering device for the facing paper of gypsum board includes a main machine, a bracket 1, a reel 3 and a facing paper 4. The facing paper 4 is assembled outside the reel 3. The reel 3 is assembled on the bracket 1 and can rotate on the bracket 1. An encoder A6 connected to one end of the reel 3 is installed on the bracket 1. The encoder A6 is electrically connected to the main machine. The encoder A6 is a device that compiles and converts the detected number of rotations and angle signals or data of the reel 3 into a signal form that can be used for communication, transmission and storage, and transmits it to the main machine. The circumference of the roller path for one rotation is calculated according to the diameter of the reel 3, and the pulse trigger signals are accumulated each time to display the paper consumption in real time. The paper consumption of each shift team is calculated through operation and statistics, automatically cleared at the time of shift change, and the paper consumption is saved. When the facing paper 4 is installed, the radius of the facing paper 4 is calculated. The thickness of the facing paper 4 is consistent. The winding length is measured through the diameter. The radius decreases by the thickness of the facing paper 4 every time it rotates one week, so as to calculate the unwinding length. This calculation formula is prior art and will not be elaborated here. Thus, the usage length of the facing paper 4 is calculated through calculation, and the purpose of measuring the usage amount of the facing paper 4 is achieved.

[0027] In a preferred embodiment, a vertical shaft 18 is further installed inside the bracket 1. A vertically slidable sleeve 17 is installed outside the vertical shaft 18. A support 15 and a rack 14 are assembled on the sleeve 17. An encoder B21 is installed inside the bracket 1. The rotating shaft of the encoder B21 is engaged with the rack 14 through a gear 19. By means of calculation, there will usually be a certain error. In order to improve the accuracy of its calculation, the encoder B21 is added. A rotatable contact wheel 16 is installed on the support 15. The contact wheel 16 is in contact with the facing paper 4. During the use of the facing paper 4, the contact wheel 16 is driven to rotate to reduce contact friction. The contact wheel 16 of the support 15 is always in contact with the outer side of the facing paper 4. Taking the reel 3 as the center, the distance between the contact wheel 16 and the reel 3 is used as the radius for debugging. During the movement of the contact wheel 16, the encoder B21 will be driven to work. The encoder B21 works to transmit the radius value in real time. By calculating the real-time radius value and the number of turns counted by the encoder A6, the length of each turn of the facing paper 4 unwound is measured, saved and summed to obtain a more accurate used length of the facing paper 4.

[0028] In a preferred embodiment, the rack 14 drives the rotating shaft of the encoder B21 to rotate through the gear 19. The encoder B21 is electrically connected to the host computer. By setting, the actual vertical movement distance of the rack 14 when driving the encoder B21 to rotate one week is obtained, so as to obtain an accurate radius value.

[0029] In a preferred embodiment, both the vertical shaft 18 and the rack 14 are perpendicular to the ground, and the vertical shaft 18 and the rack 14 are parallel to each other. The movement track of the rack 14 is the same as that of the vertical shaft 18. In order to keep the rack 14 always in contact with the gear 19 and the transmission efficiency, a traction ring 20 can also be installed on the bracket 1. The traction ring 20 is slidably connected to the rack 14 through a slide rail to keep the sliding track of the rack 14.

[0030] In a preferred embodiment, a spring member 13 is installed at the bottom of the sleeve 17. The spring member 13 is located outside the vertical shaft 18. The spring member 13 applies an upward force to the contact wheel 16 through the sleeve 17 so that it can always keep in contact with the surface of the facing paper 4 and adjust the position according to the paper usage.

[0031] In a preferred embodiment, an adjustment assembly 2 is installed at the top of the bracket 1;

[0032] The adjustment assembly 2 is a lead screw dovetail slide. A U-shaped shaft seat is installed at the top of the lead screw dovetail slide. A rotatable roller is installed in the U-shaped shaft seat and is in contact with the reel 3. The lead screw dovetail slide is a prior art and can adjust the distance in the x and y axes. When the contact position between the contact wheel 16 and the facing paper 4 is not perpendicular and the accurate radius of the facing paper 4 is not measured, the position of the facing paper 4 is adjusted by adjusting the lead screw dovetail slide for fine adjustment.

[0033] In a preferred embodiment, the encoder A6 is connected to the reel 3 through a connector 7;

[0034] The connector 7 includes a threaded connecting rod 8, a nut 11, a slot 9 and a docking head 10. The threaded connecting rod 8 is fixed to the rotating shaft of the encoder A6. The docking head 10 is installed at one end of the reel 3. A slot 9 matching the docking head 10 is provided on the threaded connecting rod 8. The outer side of the threaded connecting rod 8 is threadedly connected with the nut 11. A positioning bolt 12 is provided on the nut 11. The connector 7 is a quick-release structure. The masking paper 4 will be replaced after use. Therefore, the reel 3 is a replaceable part. The stability of the docking is ensured by screwing the nut 11 in and out. The positioning bolt 12 also plays a certain role in fixing the nut 11 to prevent the nut 11 from unscrewing during rotation.
