Description

Technical Field

[0001] This utility model belongs to the field of tent production technology, and in particular to a printing device for tent production. Background Technology

[0002] A tent is a shelter erected on the ground to protect against wind, rain, and sunlight, and to provide temporary accommodation. It is usually made of canvas and can be disassembled and moved at any time, along with its supporting structure. Tents are carried in parts and assembled on-site.

[0003] Existing inkjet printing equipment for tent production cannot be flipped after clamping the canvas, and can only be sprayed on one side. When multiple sides need to be sprayed, manual flipping is required, which wastes manpower and reduces efficiency.

[0004] For example, (authorization announcement number CN215404970U) describes a spraying device for producing tent fabric. A brush evenly applies a smoothing liquid sprayed onto the fabric surface, and a tank collects excess liquid brushed off to prevent waste. A cooling mechanism ensures adequate cooling of the tent fabric. However, this device has the problem that it requires manual turning during use to rotate the fabric that needs multi-sided spraying, reducing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a printing device for tent production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a printing device for tent production, comprising a box for protecting the tent during production and preventing ink spillage, and a bottom block at the bottom of the box; a connecting frame is fixed to the vertical side of the box, a second linear motor is installed at the top of the connecting frame, the output end of the second linear motor is connected to a moving block extending into the box via a second lead screw, the moving block has a groove on its vertical side, a rotary motor is installed vertically inside the groove, the output end of the rotary motor is connected to a mounting frame via a rotating shaft, the mounting frame has a moving groove on its vertical side away from the connecting frame, and a third linear motor is installed on the side of the mounting frame;

[0007] The output end of the third linear motor is connected to two connecting plates via a bidirectional lead screw. A limit frame is fixed on one side of the two connecting plates that are close to each other. Telescopic rods are installed at the top and bottom of the limit frames. A clamping plate is installed on one side of the moving part of the two telescopic rods.

[0008] In a further embodiment, a vertical plate much higher than the box body is fixed to the top of the base block.

[0009] In a further embodiment, a first linear motor is installed at the top of the vertical plate, and the output end of the first linear motor is connected to a movable plate via a first lead screw.

[0010] In a further embodiment, a top cover is fixed to the vertical side of the movable plate.

[0011] In a further embodiment, four rollers are fixed to the bottom end of the base block.

[0012] In a further embodiment, a liquid storage tank for storing inkjet ink is fixed to the top of the top cover, and an inlet pipe is installed at the top of the liquid storage tank.

[0013] In a further embodiment, the bottom end of the top cover is fixed with an inlay plate that is close to the inner wall of the box, and the bottom end of the inlay plate is equipped with multiple printheads for printing during the tent production process.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] The inkjet printing device used in tent production, during use, drives the moving plate and top cover to move via a first linear motor located at the top of the vertical plate. This allows the inlay plate at the bottom of the top cover to be inserted into the box after the canvas is installed, forming a sealed state and preventing inkjet liquid from overflowing.

[0016] This inkjet printing device for tent production operates by using a mounting frame inside the housing. A third linear motor on the side of the mounting frame drives two connecting plates on the outer periphery of a bidirectional lead screw, causing two limiting frames to move closer or further apart. Telescopic rods at the top and bottom of the limiting frames clamp the canvas, facilitating the fixing of canvases of different sizes. When multi-sided painting is required, a second linear motor at the top of the connecting frame moves a moving block on the outer periphery of the second lead screw upwards, positioning the mounting frame at a distance that prevents it from bumping against the inner wall of the housing. A rotary motor located on the inner wall of a groove on the vertical side of the moving block then rotates the mounting frame, automatically flipping the canvas over, saving manpower and improving efficiency. This inkjet printing device for tent production prevents ink spillage, facilitates the fixing of canvases of different sizes, and automatically flips the canvas over, saving manpower and improving efficiency.

[0027] Example

[0028] like Figures 1 to 4 The inkjet printing device for tent production shown includes a box 1 for protecting the inkjet liquid from overflowing during tent production and a bottom block 7 set at the bottom of the box 1.

[0029] To facilitate multi-sided spraying of the canvas, a connecting frame 10 is fixed to the vertical side of the housing 1. A second linear motor 13 is installed at the top of the connecting frame 10. The output end of the second linear motor 13 is connected to a moving block 19 extending into the housing 1 via a second lead screw. The vertical side of the moving block 19 has a groove, and a rotary motor 18 is installed vertically inside the groove. The output end of the rotary motor 18 is connected to a mounting frame 14 via a rotating shaft. The vertical interior of the mounting frame 14 away from the connecting frame 10 has a moving groove. A third linear motor 16 is installed on the side of the mounting frame 14. Through the mounting frame 14 inside the housing 1, the third linear motor 16 on the side of the mounting frame 14 drives the two connecting plates on the outer periphery of the bidirectional lead screw to move towards each other, causing the two limiting frames 17 to move closer or further apart. The telescopic rods 15 at the top and bottom of the limiting frames 17 drive the clamping plate 12 to clamp the canvas, making it easy to fix canvases of different sizes.

[0030] When multi-sided spraying is required, the second linear motor 13 at the top of the connecting frame 10 drives the moving block 19 on the outer periphery of the second lead screw to move upward, so that the mounting frame 14 is moved to a distance that will not bump into the inner wall of the box 1. Then, the rotary motor 18 set in the inner wall of the groove on the vertical side of the moving block 19 drives the mounting frame 14 to rotate, so that the canvas is automatically flipped, saving manpower and improving efficiency. The output end of the third linear motor 16 is connected to two connecting plates through a bidirectional lead screw. The two connecting plates are fixed with a limit frame 17 on the side that is close to each other. The top and bottom ends of the limit frame 17 are equipped with telescopic rods 15. The moving part of the two telescopic rods 15 is equipped with a clamping plate 12 on one side.

[0031] A vertical plate 3, much higher than the box body 1, is fixed to the top of the base block. A first linear motor 4 is installed at the top of the vertical plate 3. A movable plate 5 is connected to the output end of the first linear motor 4 through a first lead screw. A top cover 2 is fixed to the vertical side of the movable plate 5. Four rollers 11 are fixed to the bottom of the base block 7. A liquid storage tank 6 for storing inkjet ink is fixed to the top of the top cover 2. An inlet pipe is installed at the top of the liquid storage tank 6. An inlay plate 8, which is close to the inner wall of the box body 1, is fixed to the bottom of the top cover 2. Multiple printheads 9 for inkjet printing during tent production are installed at the bottom of the inlay plate 8. The first linear motor 4, located at the top of the vertical plate 3, drives the movable plate 5 and the top cover 2 to move, so that the inlay plate 8 at the bottom of the top cover 2 can be inserted into the box body 1 after the canvas is installed, forming a closed state to prevent inkjet ink from overflowing.

[0032] The first linear motor 4, the second linear motor 13, the third linear motor 16, the rotary motor 18, and the telescopic rod 15 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0033] Working principle

[0034] The spray painting device for tent production operates by using a third linear motor 16 located on the side of the mounting frame 14 to drive two connecting plates on the outer periphery of the bidirectional lead screw to move towards each other, causing the two limiting frames 17 to move closer or further apart. Telescopic rods 15 located at the top and bottom of the limiting frames 17 then drive clamping plates 12 to hold the canvas, followed by spraying with a nozzle 9. Next, a second linear motor 13 located at the top of the connecting frame 10 on the side of the housing 1 drives a moving block 19 on the outer periphery of the second lead screw to move up and down, causing the moving block 19 to synchronously move the mounting frame 14. Once a certain distance is reached, a rotary motor 18 located on the inner wall of the groove drives the mounting frame 14 to rotate, spraying the other side.
