Description

Technical Field

[0001] The invention relates to the technical field of gypsum board processing, and in particular to a gypsum board coating and feeding device. Background Art

After the protective film is used up, the film roll is replaced mechanically or manually according to the size of the film roll and production conditions. In this process, since the laminating feeding device is arranged above the linear conveying device, its height and position make it inconvenient to replace the film roll, and there is a possibility that the film roll falls during replacement and operation, causing damage to the linear conveying device and the product, and there are safety hazards, especially when the film roll is replaced manually.

[0036] 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.

[0037] like Figures 1 to 4 As shown, the present invention provides a gypsum board coating feeding device, comprising:

[0038] The end guide roller frame 1 is arranged above the linear conveying device 2 and has a guide roller group 3 composed of a plurality of guide rollers, and the guide roller group 3 is used to guide the film to be conveyed in the conveying direction of the linear conveying device 2;

[0039] A side vertical roller frame 4, which is arranged on one side of the linear conveying device 2 and has a film roll driving mechanism 5 for rotating and installing a film roll;

[0040] The intermediate reversing roller frame 6 is arranged in front of the end guide roller frame 1 and has a rotatable reversing roller 7. The reversing roller 7 is parallel to the plane where the guide roller and the film roll are located, and the reversing roller 7 is inclined relative to the guide roller and the film roll. The film released from the film roll on the film roll driving mechanism 5 is conveyed to the guide roller group 3 after passing through the reversing roller 7.

[0041] The present invention reverses the film released from the film roll by the reversing roller 7 on the intermediate reversing roller frame 6, so that the film released from the film roll on the side vertical roller frame 4 on one side of the linear conveying device 2 is conveyed to the guide roller group 3 on the end guide roller frame 1 above the linear conveying device 2 after reversing, and the film roll is arranged on the side of the linear conveying device 2 through the side vertical roller frame 4, which is not only conducive to the replacement of the film roll by equipment and manual labor, but also reduces the requirements for the film roll replacement equipment and the energy consumption of lifting the film roll, and reduces the risk and labor intensity of manual replacement of the film roll. In addition, it also avoids the situation where the film roll is arranged above the linear conveying device 2 and there is a risk of the film roll falling, causing damage to the linear conveying device 2 and the conveyed products.

[0042] In addition, the reversing roller 7 is a rotating body structure whose side surface is concave in the axial direction to form a waist, and the concave point on the side surface of the reversing roller 7 is located in the radial direction of the center of the reversing roller 7 itself, and the concave point on the side surface of the reversing roller 7 is located between the two sides of the film output by the reversing roller 7. The reversing roller 7 is symmetrical about the center at both ends and has a waist with a concave side surface, so that the film is kept at the center position of the reversing roller 7, that is, it has the function of preventing the film from deviating.

[0043] The reversing roller 7 is arranged horizontally, and the angles between the film input section of the input reversing roller 7 and the film output section of the output reversing roller 7 and the reversing roller 7 are both 45°, so that both sides of the film input section and the film output section are evenly stressed on the reversing roller 7, so that the film is kept at the center of the reversing roller 7. In addition, the film roll can also be made parallel to the side of the linear conveying device 2, which is conducive to reducing the floor space occupied by the side vertical roller frame 4.

[0044] The foot of the center of the reversing roller 7 on the film output section is located on the center line of the film output section, which is particularly beneficial to the stability of the position of the film output section.

[0045] Furthermore, in order to prevent the film output section from deviating from the predetermined path due to mechanical vibration, film roll installation error, etc., a deviation detection module 8 is provided at the tail end of the intermediate transfer roller frame 6 close to the end guide roller frame 1. The deviation detection module 8 is used to detect whether the film output section is in the center position aligned with the gypsum board below;

[0046] The end of the reversing roller 7 is slidably arranged on the intermediate reversing roller frame 6 through the offset correction mechanism 9, and the offset correction mechanism 9 is electrically connected to the offset detection module 8;

[0047] When the deviation detection module 8 detects that the film output section deviates from the center position, it controls the deviation correction mechanism 9 to drive the reversing roller 7 to reciprocate, so that the film output section reciprocates along the reversing roller 7 and is corrected to be aligned with the center position.

[0048] When the film released by the existing laminating and feeding device deviates laterally due to the deviation of the film roll position, the film roll position needs to be readjusted, that is, the film roll needs to be moved axially. However, especially in the early stage of film roll use, moving the film roll is not only laborious, but also increases the labor intensity and operation risk of workers, as well as energy consumption, and causes large mechanical wear, which reduces the service life of the laminating and feeding device.

[0049] The present invention reverses the direction of the film released from the film roll by means of the reversing roller 7, and adjusts the position of the film in the directions of both sides by horizontally rotating the reversing roller 7. As a part of the feeding device for guiding and conveying the film, the present invention breaks the convention by tilting the reversing roller 7 in the horizontal direction, and drives the reversing roller 7 to swing in the horizontal direction by means of the offset correction mechanism 9, which not only enables the film roll to be set on the side of the linear conveying device 2 through the side vertical roller frame 4, but also enables the position of the film to be flexibly adjusted in the directions of both sides.

[0050] However, the existing arrangement of the conveying rollers has an insufficient initial tilt angle of the conveying rollers, and it is difficult to effectively and efficiently adjust the position of the film when the conveying rollers are tilted slightly.

[0051] In addition, the reason why a pair of rubber rollers are not used to clamp the film to limit the deviation and tilt is that the rubber rollers may cause the film to deviate and tilt due to dimensional errors, assembly errors, etc., and once the above situation occurs, it is difficult for the film to slide along the rubber rollers, making it difficult to adjust the position and angle of the film in time.

[0052] Furthermore, both ends of the reversing roller 7 are slidably arranged on the intermediate reversing roller frame 6 through the offset correction mechanism 9, and the offset correction mechanisms 9 at both ends synchronously drive the two ends of the reversing roller 7 to swing in the same direction, so that the two ends of the reversing roller 7 can swing back and forth around their own midpoints. This is to avoid the other end of the reversing roller 7 having no driving force and can only move in another direction relying on the pulling force of the film output section, which makes it difficult for the film output section to reciprocate along the reversing roller 7 flexibly and accurately. Therefore, the advantage of both ends of the reversing roller 7 being slidably arranged on the intermediate reversing roller frame 6 through the offset correction mechanism 9 is that it is conducive to reducing the reciprocating swing amplitude of the reversing roller 7, and flexibly, efficiently and accurately correcting the position of the film output section.

[0053] The offset correction mechanism 9 includes an arc-shaped transmission slider 901, a sliding shaft seat 902 and a shaft seat driving assembly 903. Arc-shaped slide grooves 14 are provided at both ends of the intermediate reversing roller frame 6. The center of the arc-shaped slide groove 14 is located on the vertical line of the center of the reversing roller 7. The arc-shaped transmission slider 901 slides and cooperates with the arc-shaped slide groove 14.

[0054] The end of the reversing roller 7 is rotatably arranged on the sliding shaft seat 902 , and the sliding shaft seat 902 is connected to the shaft seat driving assembly 903 through the arc-shaped transmission slider 901 , so that the shaft seat driving assembly 903 drives the sliding shaft seat 902 to reciprocate through the arc-shaped transmission slider 901 .

[0055] The shaft seat driving assembly 903 includes a track guide plate 9031, a synchronous transmission belt 9032, a driving wheel 9033 and a driving motor 9034. The track guide plate 9031 is arranged on the inner side of the arc-shaped transmission slider 901 and fits with the arc-shaped transmission slider 901. The driving wheel 9033 is sleeved on the track guide plates 9031 at both ends and connected through the synchronous transmission belt 9032. The synchronous transmission belt 9032 is slidably matched with the outer side of the track guide plate 9031. The arc-shaped transmission slider 901 is connected to the end of the synchronous transmission belt 9032.

[0056] The driving wheel 9033 is rotatably set in the intermediate conversion roller frame 6, and the driving wheel 9033 is meshed with the outer side of the synchronous transmission belt 9032 through a toothed structure. The driving motor 9034 is connected to the driving wheel 9033 to drive the arc-shaped transmission sliders 901 at both ends to move synchronously and in the same direction through the driving wheel 9033 and the synchronous transmission belt 9032.

[0057] The track guide plate 9031 and the driving wheel 9033 clamp the synchronous transmission belt 9032 so that the synchronous transmission belt 9032 with a toothed structure on the outside can be meshed with the driving wheel 9033 with a toothed structure on the side. The arc-shaped slide groove 14 and the track guide plate 9031 are used to adapt to the horizontal track of the end of the annular roller when the reversing roller 7 rotates, so that the synchronous transmission belt 9032 can drive the end of the reversing roller 7 to rotate horizontally around its own center through the transmission block and the sliding shaft seat 902, so as to adjust the angle of the reversing roller 7, so that the film passing through the reversing roller 7 moves to the left or right due to the traction force of the film output section. After detecting that the film output section is aligned with the center position or is about to be aligned, the offset detection module 8 controls the drive motor 9034 to rotate in the opposite direction, so that the reversing roller 7 returns to a 45° tilted state after the film output section is aligned with the center position.

[0058] Furthermore, the provision of the synchronous transmission belt 9032 enables the two ends of the reversing roller 7 to rotate horizontally synchronously and in the same direction by the same driving motor 9034, so as to improve the accuracy of the reversing roller 7 in adjusting the film position.

[0059] A movable docking part 10 is arranged on the inner side of the side vertical roller frame 4 facing the linear conveying device 2. The movable docking part 10 is connected to a fixed docking part 11 through a fastener. The fixed docking part 11 is arranged on the side of the linear conveying device 2. In addition, a vertical docking slot 12 is vertically arranged on the fixed docking part 11 near the outer side of the movable docking part 10. A vertical docking guide rail 13 is arranged on the inner side of the movable docking part 10 and is plugged into and vertically slidably matched with the fixed docking part 12.

[0060] That is, the side vertical roller frame 4 is detachably arranged on the side of the linear conveying device 2 by fasteners connecting the fixed docking portion 11 and the movable docking portion 10, so that when the film roll driving mechanism 5 on the side vertical roller frame 4 fails, the production can be promptly restored by replacing the spare side vertical roller frame 4 as a whole. The existence of the reversing roller 7 enables the film roll driving mechanism 5 to be arranged on the side of the linear conveying device 2 instead of on the top through the side vertical roller frame 4, which is the premise for the rapid replacement of the side vertical roller frame 4.

[0061] The function of the movable docking part 10 and the fixed docking part 11 slidingly cooperating in the vertical direction through the fixed docking part 12 and the vertical docking guide rail 13 is to limit the assembly position of the side vertical roller frame 4 relative to the reversing roller 7 in the axial direction and vertical direction of the film roll, so as to reduce the position error of the film output section output by the reversing roller 7 in the two-way direction. And within a reasonable range, the requirement for the film roll height that does not affect the position of the film output section is reduced, that is, the requirement for the height of the side vertical roller frame 4 relative to the reversing roller 7 is reduced, so that the vertical docking guide rail 13 on the movable docking part 10 can be slidably plugged and matched with the fixed docking part 12, which is conducive to the assembly of the side vertical roller frame 4 on the linear conveying device 2.

[0062] In addition, multiple movable docking parts 10 and fixed docking parts 11 are provided to reduce the force on a single movable docking part 10 and fixed docking part 11, which is beneficial to prolonging the service life of the movable docking part 10 and the fixed docking part 11.

[0063] The fasteners are bolts, buckles or other fasteners with equivalent functions that connect the fixed docking portion 11 and the movable docking portion 10 .

[0064] 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.
