Abstract

This invention provides a coding system for gypsum board production, including a frame, a support frame, two side-by-side mounting brackets, and a drive mechanism. The frame is mounted on an assembly line. The support frame is slidably mounted laterally on the frame, positioned above the assembly line. The two mounting brackets are slidably mounted vertically on the support frame, each mounting bracket capable of mounting a printhead from a coding machine. The drive mechanism drives the support frame to slide laterally on the frame and also drives the mounting brackets to slide vertically on the support frame. This invention, by driving the support frame laterally and the two mounting brackets vertically via the drive mechanism, allows the printhead positions on the two mounting brackets to be interchanged, ensuring consistency after coding of the gypsum board. Furthermore, the system maintains continuous operation of the assembly line during the interchange process, avoiding wasted time and reduced production efficiency.

Description

Technical Field

[0001] This invention relates to the field of gypsum board production equipment technology, specifically to a coding system for gypsum board production. Background Technology

[0002] Inkjet printers are a type of marking equipment widely used in various industries, suitable for printing logos, text, production dates, QR codes, and other markings on products.

[0003] In the production of gypsum board, inkjet printing is required. In practice, gypsum board is conveyed on an assembly line, and the inkjet printer is fixedly mounted on the line, with its printhead positioned above the gypsum board to complete the printing operation. Over long-term use, the printhead requires repair or maintenance, necessitating the shutdown of the assembly line and removal of the printhead, resulting in wasted time and reduced production efficiency.

[0061] See Figures 1 to 7 This embodiment provides a coding system for gypsum board production, including a frame 10, a support frame 20, two mounting frames 30 arranged side by side, and a drive mechanism 50.

[0062] A frame 10 is mounted on an assembly line. A support frame 20 is slidably mounted laterally on the frame 10, located above the assembly line. Two mounting brackets 30 are slidably mounted vertically on the support frame 20, each mounting bracket 30 capable of mounting a printhead 40 of an inkjet printer. Other components of the inkjet printer (not shown) are also mounted on the frame 10, and these components can be connected to the two printheads 40. A drive mechanism 50 is used to drive the support frame 20 to slide laterally on the frame 10, and the drive mechanism 50 is also used to drive the mounting brackets 30 to slide vertically on the support frame 20.

[0063] In this embodiment, due to factors such as the large amount of dust in the gypsum board production site, the changes in gypsum board thickness causing occasional collisions between the gypsum board and the inkjet printer nozzle 40, and the relatively dry gypsum production site making it easy for the ink to evaporate moisture, the inkjet printer nozzle 40 needs to be inspected and maintained frequently.

[0064] Two mounting brackets 30 on the support frame 20 each hold two printheads 40, arranged side-by-side horizontally above the production line. Only one printhead 40 is in the working position at a time to perform the coding operation. The printheads 40 on the gypsum board production line require periodic inspection or maintenance. When a working printhead 40 needs maintenance, the other printhead 40 needs to be moved to the working position to perform the coding operation, thus achieving position interchange. The working positions of the two printheads 40 are identical to ensure consistency after the gypsum board coding operation, and the production line must continue to operate throughout the process.

[0065] Specifically, when the printhead 40 at the working position requires maintenance, the drive mechanism 50 drives the mounting bracket 30 corresponding to the printhead 40 to move upward, causing the printhead 40 to move upward away from the working position and away from the production line. Then, the drive mechanism 50 drives the support frame 20 to move laterally, moving another printhead 40 above the working position. Finally, the drive mechanism 50 drives this first printhead 40 to move downward back to the working position for operation. During this process, both printheads 40 are in the same working position sequentially, and their distance from the production line is the same, thus ensuring the quality of the printing. During the replacement of the printhead 40, the production line does not need to be shut down. After the printhead 40 is replaced, the printhead 40 awaiting maintenance can be easily removed from the mounting bracket 30. This avoids wasted time and reduced production efficiency.

[0066] In one embodiment, the support frame 20 includes a bottom support 21, a side support 22, and a middle support 23.

[0067] The bottom support 21 is laterally slidably mounted on the frame 10; two side supports 22 are provided, each connected to one end of the bottom support 21, and the side supports 22 are located above the bottom support 21. The middle support 23 is connected to the middle of the bottom support 21, and the middle support 23 is located above the bottom support 21.

[0068] The central support 23 and the two side supports 22 form two mounting positions 24. The mounting bracket 30 is slidably installed vertically in the mounting position 24. The mounting bracket 30 is subjected to an upward elastic force within the mounting position 24. The drive mechanism 50 can abut against one of the mounting brackets 30 to move it downward. The drive mechanism 50 is also used to drive the bottom support 21 to slide laterally. Specifically, the inner sides of the two side supports 22 are provided with vertical sliding grooves, and the two sides of the central support 23 are respectively provided with vertical sliding grooves. The two ends of the mounting bracket 30 slide vertically with the sliding grooves of the side supports 22 and the sliding grooves of the central support 23.

[0069] In this embodiment, the two mounting brackets 30 can move vertically within the two mounting positions 24, and the mounting brackets 30 are also subjected to an upward elastic force. The drive mechanism 50 drives the base bracket 21 to slide laterally on the frame 10, thereby changing the position of the nozzles 40 on the two mounting brackets 30, allowing the nozzles 40 to move above the working position or to move away from the working position. The drive mechanism 50 abuts against one of the mounting brackets 30, causing the mounting bracket 30 and its nozzles 40 to move downward to the working position for coding operations. The other mounting bracket 30 is subjected to an upward elastic force, causing the nozzles 40 on the mounting bracket 30 to move upward for subsequent disassembly, maintenance, and repair.

[0070] In one embodiment, a guide member 25 is also connected to the bottom support 21. The guide member 25 is located between the two side supports 22. The upper end of the guide member 25 has two symmetrical guide ramps 251, which are inclined towards the corresponding side supports 22. Specifically, the guide member 25 is connected to the middle support 23.

[0071] The drive mechanism 50 includes a drive component 51 and a power mechanism.

[0072] The drive assembly 51 is vertically movable and mounted on the frame 10. The drive assembly 51 can sequentially abut against different guide ramps 251 to drive the guide member 25 to move laterally. The drive assembly 51 can also abut against the corresponding mounting bracket 30 to drive the mounting bracket 30 to move downward against the elastic force. The power mechanism is used to drive the drive assembly 51.

[0073] In this embodiment, the drive assembly 51 moves up and down on the frame 10 under the drive of the power mechanism. During the up and down movement of the drive assembly 51, it can sequentially abut against different guide ramps 251, specifically, as shown in... Figure 3 That is, the current drive assembly 51 abuts against the left guide ramp 251 and continues to move downwards, driving the guide member 25 to move to the right. The next time, the drive assembly 51 abuts against the right guide ramp 251 in the figure, driving the guide member 25 to move to the left. At the same time, during the downward movement of the drive assembly 51, it will also abut against the mounting bracket 30, thereby causing the mounting bracket 30 to move downwards.

[0074] Overall, Figure 3 In this scenario, assuming the nozzle 40 on the left mounting bracket 30 is a normally functioning nozzle 40 and needs to be moved to the working position, driven by the drive assembly 51, the guide member 25 moves to the right, causing the nozzle 40 on the left mounting bracket 30 to move directly above the working position. Simultaneously, the left mounting bracket 30, along with its nozzle 40, gradually moves downwards to the working position under the pressure of the drive assembly 51. That is, the drive assembly 51 both drives the support bracket 20 to slide laterally and drives the mounting bracket 30 to move downwards, and both actions occur simultaneously.

[0075] Figure 3 In the above scenario, assuming that the nozzle 40 on the left mounting bracket 30 is the nozzle 40 to be maintained, the drive assembly 51 moves upward. Under the action of the elastic force, the nozzle 40 on the left mounting bracket 30 moves upward away from the working position. Then, after the drive assembly 51 moves upward to a certain position, it moves downward again and abuts against the guide surface on the right side of the guide member 25. This drives the guide member 25 to move to the left to the previous position of the left mounting bracket 30 (above the working position). At the same time, the drive assembly 51 drives the right mounting bracket 30 to move downward and closer to the working position during the leftward movement.

[0076] In one embodiment, the guide 25 includes a vertical guide block 252 and a diagonal guide block 253.

[0077] Two vertical guide blocks 252 are arranged parallel to each other, and both vertical guide blocks 252 are connected to the base bracket 21. The two vertical guide blocks 252 are located between the two side brackets 22. Two inclined guide blocks 253 are arranged symmetrically to each other, and each inclined guide block 253 is connected to its corresponding vertical guide block 252. The ends of the two inclined guide blocks 253 away from the vertical guide blocks 252 are connected to each other. The upper end surfaces of the two inclined guide blocks 253 are guide slopes 251. The upper contour of the entire guide component 25 is an isosceles triangle, and the lower contour is a rectangle.

[0078] In this embodiment, the drive assembly 51 abuts against the upper ends of the two inclined guide blocks 253 respectively to drive the guide 25 to move laterally on the frame 10.

[0079] In one embodiment, the drive assembly 51 includes a slider 511, a drive rod 513, a first connector 514, and a contact assembly 52. ​​The slider 511 is vertically slidable on the frame 10 and has a through mounting hole 512. The drive rod 513 passes through the mounting hole 512 and is coaxially rotatably connected to it. The first connector 514 is connected to the outer peripheral wall of the end of the drive rod 513. The contact assembly 52 is connected to the end of the first connector 514 away from the drive rod 513, and the contact assembly 52 can abut against the guide ramp 251.

[0080] The power mechanism drives the slider 511 to slide, and the drive rod 513 can be rotated so that the contact component 52 abuts against different guide slopes 251. The drive rod 513 can remain stationary within the mounting hole 512. Specifically, the power mechanism includes a motor mounted on the frame 10, the output end of the motor is connected to a coaxial transmission rod, the slider 511 has a vertical transmission hole, and the transmission rod is threadedly connected to the transmission hole, thereby driving the slider 511 to move vertically by rotating the transmission rod.

[0081] In this embodiment, the drive rod 513 rotates, causing the contact component 52 to move in an arc trajectory around the axis of the drive rod 513, so that the contact component 52 can be located above the two guide slopes 251 at different times, that is, the contact component 52 can abut against different guide slopes 251. Then, under the drive of the slider 511, the guide component 25 is driven to move laterally by the contact component 52.

[0082] In one embodiment, the drive assembly 51 further includes a second connecting rod 515, a mounting shaft 516, a limiting shaft 517, a fixing shaft 518, and a first spring 519.

[0083] The second connecting rod 515 is connected to the outer wall of the end of the drive rod 513 away from the first connecting member 514. The length direction of the second connecting rod 515 is the same as the radial direction of the drive rod 513. The mounting shaft 516 is connected to the end of the connecting rod away from the drive rod 513. The axis of the mounting shaft 516 is parallel to the axis of the drive rod 513. Two limiting shafts 517 are provided. The two limiting shafts 517 are respectively connected to the slider 511. Both limiting shafts 517 are located below the drive rod 513. The axes of the two limiting shafts 517 are on the same horizontal plane. The limiting shafts 517 can abut against the second connecting rod 515. The fixed shaft 518 is connected to the slider 511. The axis of the fixed shaft 518 is parallel to the axis of the drive rod 513. The fixed shaft 518 is located directly below the drive rod 513. The two ends of the first spring 519 are rotatably connected to the fixed shaft 518 and the mounting shaft 516, respectively. Specifically, two collars can be provided at both ends of the first spring 519, and the two collars are respectively rotatably sleeved on the fixed shaft 518 and the mounting shaft 516.

[0084] In this embodiment, the drive rod 513 can only rotate 180 degrees, and the second connecting rod 515 connected to the drive rod 513 will abut against the limiting shaft 517. When the second connecting rod 515 abuts against the limiting shaft 517, the center line of the second connecting rod 515 is parallel to the horizontal plane. At this time, the first spring 519 is in its normal state. Once the drive rod 513 tends to rotate, the first spring 519 is stretched, and the elastic force acts on the drive rod 513, so that the drive rod 513 remains stationary in the mounting hole 512. This means that the drive rod 513 can remain stationary before rotation and after rotating 180 degrees.

[0085] In one embodiment, a stop 26 is connected to the upper end of the side bracket 22; after the contact component 52 moves upward, it abuts against the lower end face of the corresponding stop 26. After the contact component 52 moves downward, it abuts against the mounting bracket 30. The length of the stop 26 is less than the distance between the drive rod 513 and the corresponding side bracket 22. Specifically, the lower end face of the stop 26 can be a slope, so that when the contact component 52 abuts against it, it can gradually move away from the side bracket 22 along the slope, thereby realizing the rotation of the drive rod 513.

[0086] In this embodiment, refer to Figure 3As the slider 511 rises, the contact component 52 abuts against the stop block 26. Since the rotation center of the contact component 52 is on the axis of the drive rod 513, the contact component 52 rotates 90 degrees counterclockwise around the drive rod 513, and then rotates to be directly below the drive rod 513. At this time, the second connecting rod 515 behind it also rotates 90 degrees, and the first spring 519 is stretched to its maximum length. With the help of inertia, the contact component 52 rotates further by a small angle. Driven by the external force of the first spring 519, the contact component 52 is located above the mounting position 24 on the right side. Then the slider 511 moves down, and the contact component 52 abuts against the guide ramp 251 on the right side, pushing the guide 25 and the support frame 20 to move to the left.

[0087] In one embodiment, the contact assembly 52 includes two rotating shafts 521, both of which are rotatably connected to the first connector 514. The axes of both rotating shafts 521 are parallel to the axis of the drive shaft. The axes of the two rotating shafts 521 form a first surface. The projection of the drive rod 513 onto the first surface is located at the exact center of the two rotating shafts 521, and the distance between the drive rod 513 and the two rotating shafts 521 is the same. Specifically, the drive shaft and the two rotating shafts 521 are located at the three angles of an acute triangle, and the acute triangle is isosceles.

[0088] In this embodiment, as Figure 3 With the two rotating shafts 521 positioned such that when the contact assembly 52 is located within the mounting position 24 on the left, the two rotating shafts 521 are in a vertical direction. As the slider 511 moves upward, the upper rotating shaft 521 contacts the lower end face of the stop block 26, causing the rotating shaft 521 to drive the drive rod 513 to rotate. It should be noted that the upper rotating shaft 521 and the drive rod 513 are not initially at the same level. Due to the obstruction of the stop block 26, the rotating shaft 521, which was originally at the upper position, eventually rotates to directly below the drive rod 513. The rotation angle of this rotating shaft 521 is greater than 90 degrees, which causes the rotation angle of the drive rod 513 to also be greater than 90 degrees. This causes the first spring 519 to go through its maximum extension phase and begin to contract, allowing the rotating shaft 521 to naturally rotate to the upper position 24 on the right after passing the stop block 26. Then, the slider 511 moves downward, and the rotating shaft 521 abuts against the guide inclined surface 251 on the right, starting to push the guide member 25 and the support frame 20 to move to the left. Driven by the drive rod 513, the rotating shaft 521 moves upward with the slider 511 and can rotate in conjunction with the stop block 26, thus moving from one mounting position 24 to another. The rotating shaft 521 can also push the support frame 20 and the nozzle 40 on the mounting frame 30 to move laterally, and the rotating shaft 521 can also push the mounting frame 30 and the nozzle 40 on it to move downward.

[0089] In one embodiment, the mounting bracket 30 includes a mounting plate 31 and a mounting frame 32 connected to each other; the mounting frame 32 is used to mount the nozzle 40; the upper end of the mounting plate 31 can abut against the rotating shaft 521, and the lower end of the mounting plate 31 is connected to one or more guide posts 33; the bottom bracket 21 has guide holes 211 corresponding to each guide post 33; the end of the guide post 33 away from the mounting plate 31 is slidably inserted into the corresponding guide hole 211; a second spring 34 is sleeved on the guide post 33; the two ends of the second spring 34 abut against the bottom bracket 21 and the mounting plate 31 respectively.

[0090] In this embodiment, the second spring 34 provides an upward elastic force to the mounting plate 31. Without the pressure of the rotating shaft 521, the mounting plate 31 can drive the mounting frame 32 to move upward and away from the production line.

[0091] In one embodiment, a guide channel 27 is formed between the vertical guide block 252 and the corresponding side bracket 22, allowing the rotating shaft 521 to pass through. Specifically, the width of the guide channel 27 is approximately the same as the diameter of the rotating shaft 521, so that when the slider 511 moves down, the rotating shaft 521 presses against the mounting plate 31. At this time, the elastic force of the second spring 34 increases, and the rotating shaft 521 slides into the guide channel 27, thereby keeping the two rotating shafts 521 vertical and preventing the drive rod 513 from rotating, so that the entire drive assembly 51 runs smoothly.

[0092] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of the invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
