Description

Technical Field

[0001] The utility model relates to the field of dry powder fabric equipment technology, and in particular to a novel dry powder fabric structural assembly. Background Technology

[0002] Screen printing machines, as an important part of the printing press industry, are a general term for equipment used to produce various printed materials. Their core function is to precisely transfer the ink or dry powder carried on the image portion of the printing plate to the surface of the substrate, thereby achieving the reproduction and presentation of graphic information.

[0003] A screen printing machine typically consists of key components such as a worktable, operation and control system, squeegee system, screen system, and machine body. The screen system is the crucial component for transferring images and text in a screen printing machine. It includes the screen frame and the screen. The screen frame is made of a metal material with a certain degree of elasticity and toughness, providing a stable support structure for the screen. The screen is the carrier of image and text information. By adjusting the tension and position of the screen, different printing effects can be achieved. The machine body provides mechanical support and protection for the entire screen printing machine, ensuring the stable operation of all components.

[0004] Ink screen printing machines are the most common type of screen printing machine. In the ink screen printing process, ink is first placed on a screen frame. Then, a squeegee applies pressure to the ink area of ​​the screen printing plate while simultaneously moving towards the other end of the plate. Driven by the squeegee, the ink is forced from the mesh of the image area onto the substrate, thus completing the ink transfer process. This printing method can achieve relatively fine image printing, and the ink has good fluidity, forming a uniform and clear pattern on the substrate surface.

[0005] Dry powder screen printing machines share similarities with ink screen printing machines in their basic principles. However, due to the significant differences in the physical properties of dry powder compared to liquid ink, dry powder screen printing machines face unique challenges during operation. Dry powder's flowability is far less than that of liquid ink, resulting in greater resistance as it passes through the mesh of the screen, making it difficult to transfer to the substrate as smoothly as ink. To address this issue, a powder application process is necessary in dry powder screen printing. The purpose of powder application is to evenly spread the dry powder on the screen, forming a uniform powder layer. This increases the contact area between the dry powder and the screen mesh, improving its penetration and allowing it to pass through the mesh more effectively, resulting in a more uniform and clearer powder transfer. This powder application process effectively improves the results of dry powder screen printing, producing clearer and more complete printed images.

[0006] For dry vermicelli printing machines, the uniformity and stability of the powder distribution process are difficult to control, which can easily lead to uneven distribution of dry powder on the screen frame, thus affecting the printing effect. Therefore, if the powder distribution mechanism of the dry vermicelli printing machine can achieve uniform powder distribution, it will greatly improve the quality of dry vermicelli printing. Utility Model Content

[0007] The utility model overcomes the shortcomings of the prior art and provides a novel dry powder fabric structure assembly. It achieves uniform fabric distribution by setting up a fabric distribution mechanism. The swaying seat of the fabric distribution mechanism is connected to an eccentric roller. When the eccentric roller rolls, it drives the swaying seat to swing, which can evenly distribute the dry powder on the mesh surface of the wire mesh frame, effectively avoiding the accumulation of dry powder and ensuring uniform fabric distribution.

[0008] To solve the above-mentioned technical problems, the utility model is implemented through the following technical solution:

[0009] A novel dry powder fabric structure assembly includes a material storage component and a fabric feeding mechanism disposed below the material storage component.

[0010] The storage assembly includes a feeding control component, which intermittently controls the opening and closing of the lower opening;

[0011] The fabric-making mechanism includes a swaying seat connected to an eccentric roller. When the eccentric roller rolls on the worktable, the swaying seat sways, thereby evenly distributing the dry powder in the swaying seat onto the mesh surface of the wire mesh frame.

[0012] Furthermore, a sliding frame and a movable connecting frame are provided between the material storage assembly and the material distribution mechanism;

[0013] The sliding frame is equipped with a slider, and the sliding direction of the slider is consistent with the rolling direction of the eccentric roller.

[0014] Furthermore, the movable connecting frame includes a limiting mounting frame, which is connected to a spring buffer rod. The lower end of the spring buffer rod is provided with a fisheye seat, which is connected to a rocking seat.

[0015] Furthermore, the rocking seat is provided with an opening adjustment ramp. The rocking seat is a square frame with a central opening. The lower end of the opening adjustment ramp is connected to one side of the lower end of the rocking seat. The opening adjustment ramp divides the rocking seat into two spaces. The lower part of the first space is blocked by the opening adjustment ramp, and the second space can be accessed downwards through the upper end of the opening adjustment ramp.

[0016] Furthermore, one side of the rocking seat is connected to an adjusting bolt assembly, which includes a bolt body that is slidably inserted into the rocking seat. One end of the bolt body is connected to an inner crossbar, and the other end is provided with an adjusting thread section. The adjusting thread section is connected to a nut, and a spring is provided between the nut and the rocking seat. Rotating the nut can adjust the length of the bolt body inserted into the rocking seat, thereby adjusting the position of the inner crossbar inside the rocking seat.

[0017] Furthermore, the side of the inner crossbar away from the bolt body abuts against the opening adjustment ramp;

[0018] As the length of the bolt body extending into the rocking seat increases, the inner crossbar pushes the opening adjustment ramp away from the bolt body. At this time, the gap between the opening adjustment ramp and the other side of the rocking seat becomes smaller, thus making the passage of the second space smaller.

[0019] When the length of the bolt body extending into the rocking seat decreases, the pushing distance of the inner crossbar on the opening adjustment ramp decreases, and the gap between the opening adjustment ramp and the other side of the rocking seat increases, thereby making the passage of the second space larger.

[0020] Furthermore, the material storage assembly includes a powder trough, which is connected to a feeding control component, and a powder distribution hopper is connected below the feeding control component.

[0021] Furthermore, the material storage assembly includes an upper tank, with two powder feeding channels separately arranged below the tank, and the lower ends of the two powder feeding channels are connected to the feeding control component;

[0022] The powder hopper is trapezoidal in the front projection direction, with the inlet being the short side of the trapezoid and the lower opening being the long side. The lower openings of the two powder hoppers overlap in the front projection direction.

[0023] Furthermore, the feeding control component includes a slide rail with a lower opening at the center, a sliding plate slidably connected to the slide rail, and the sliding plate connected to the opening cylinder.

[0024] The sliding plate is also provided with a sliding opening. When the sliding opening is completely aligned with the lower opening, the most powder falls from the upper tank through the powder channel into the powder hopper. When the sliding opening is completely misaligned with the lower opening, the lower opening is completely closed, and the powder no longer flows to the powder hopper.

[0025] Compared with existing technologies, the advantages of this utility model are:

[0026] 1. Uniform fabric distribution is achieved by setting up a fabric distribution mechanism. The swaying seat of the fabric distribution mechanism is connected to an eccentric roller. When the eccentric roller rolls, it drives the swaying seat to swing, which can evenly distribute the dry powder on the mesh surface of the wire mesh frame, effectively avoiding the accumulation of dry powder and ensuring uniform fabric distribution.

[0027] 2. The powder hopper's front projection is trapezoidal, with the inlet being the short side and the bottom opening being the long side. Furthermore, the bottom openings of the two powder hoppers overlap in their front projection. This design allows the powder to fall more dispersedly, increasing the coverage area of ​​the fabric, avoiding dead spots, and improving the coverage and uniformity of the powder application.

[0028] 3. By adjusting the bolt components, the position of the inner crossbar in the rocking seat can be changed, thereby pushing the opening adjustment slope plate to adjust the size of the second space channel, realizing flexible adjustment of the amount of powder, and accurately controlling the amount of powder according to different production needs.

[0038] The preferred embodiments of the utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model.

[0039] like Figs. 1 to 7 As shown, a novel dry powder fabric structure assembly is used to evenly distribute dry powder on the mesh surface of a wire mesh frame. It includes a storage component 1, which is responsible for storing dry powder and controlling the feeding. A fabric feeding mechanism 4 is provided below the storage component 1. The storage component 1 includes a feeding control component 102, which intermittently controls the opening and closing of the lower opening 1022 to achieve intermittent feeding of dry powder.

[0040] The fabric mechanism 4 includes a wobbling seat 401, which is connected to an eccentric roller 402. When the eccentric roller 402 rolls on the worktable, the wobbling seat 401 wobbles, thereby evenly distributing the dry powder in the wobbling seat 401 onto the mesh surface of the wire mesh frame.

[0041] A sliding frame 2 and a movable connecting frame 3 are provided between the material storage assembly 1 and the fabric feeding mechanism 4. A slider 201 is provided in the sliding frame 2. The sliding direction of the slider 201 is consistent with the rolling direction of the eccentric roller 402. Therefore, the sliding frame 2 bears most of the weight of the fabric structure assembly, making the fabric structure assembly move more smoothly. The movable connecting frame 3 plays a connecting and buffering role, while ensuring smooth relative movement between the components.

[0042] The movable connecting frame 3 includes a limiting mounting frame 301, which is connected to a spring buffer rod 302. The lower end of the spring buffer rod 302 is provided with a fisheye seat 303, which is connected to the rocking seat 401. Therefore, when the rocking seat 401 rocks, different points of the rocking seat 401 can be buffered by the spring buffer rod 302 at different positions, so that the rocking seat 401 does not affect the movement of the sliding frame 2 when it rocks.

[0043] The rocking seat 401 is provided with an opening adjustment ramp 404. The rocking seat 401 is a square frame with a through hole. The lower end of the opening adjustment ramp 404 is connected to one side of the lower end of the rocking seat 401. The opening adjustment ramp 404 divides the rocking seat 401 into two spaces. The lower part of the first space is blocked by the opening adjustment ramp 404, and the second space can be accessed to the lower part through the upper end of the opening adjustment ramp 404.

[0044] One side of the rocking seat 401 is connected to an adjusting bolt component 405. The adjusting bolt component 405 includes a bolt body 4051, which is slidably inserted into the rocking seat 401. One end of the bolt body 4051 is connected to an inner crossbar 503, and the other end is provided with an adjusting thread section 4054. The adjusting thread section 4054 is connected to a nut 4053. A spring 4052 is provided between the nut 4053 and the rocking seat 401. Rotating the nut can adjust the length of the bolt body 4051 inserted into the rocking seat 401, thereby adjusting the position of the inner crossbar 503 inside the rocking seat 401.

[0045] The side of the inner crossbar 503 away from the bolt body 4051 abuts against the opening adjustment ramp 404;

[0046] When the length of the bolt body 4051 extending into the rocking seat 401 increases, the inner crossbar 503 pushes the opening adjustment ramp 404 away from the bolt body 4051. At this time, the gap between the opening adjustment ramp 404 and the other side of the rocking seat 401 becomes smaller, thereby making the passage of the second space smaller.

[0047] When the length of the bolt body 4051 extending into the rocking seat 401 becomes shorter, the pushing distance of the inner crossbar 503 on the opening adjustment ramp 404 becomes smaller. At this time, the gap between the opening adjustment ramp 404 and the other side of the rocking seat 401 becomes larger, thereby making the passage of the second space larger.

[0048] Therefore, by pre-setting the position of the adjusting bolt component 405 and the inner crossbar, the size of the channel in the second space can be adjusted, thereby adjusting the amount of powder applied.

[0049] The storage assembly 1 includes a powder trough 101, which provides a relatively enclosed space to prevent dry powder leakage and external contamination, ensuring the quality and stability of the dry powder. The powder trough 101 is connected to a feeding control component 102, and a powder distribution hopper 103 is connected below the feeding control component 102.

[0050] The material storage assembly 1 includes an upper tank 1011, with two powder discharge channels 1012 separately arranged below the tank 1011. The powder discharge channels 1012 guide the dry powder in the upper tank to the discharge control component 102, realizing the orderly flow of the dry powder. The lower ends of both powder discharge channels 1012 are connected to the discharge control component 102.

[0051] The powder hopper 103 is trapezoidal in the front projection direction, with the inlet being the short side of the trapezoid and the lower opening being the long side. The trapezoidal design allows the dry powder to be more dispersed when it falls, increasing the coverage area of ​​the cloth.

[0052] The lower openings of the two powder hoppers 103 have overlapping portions in the front projection direction, which improves the distribution range and uniformity of dry powder and avoids dead corners in the powder distribution due to insufficient material feeding at the edges of the powder hoppers 103.

[0053] The feeding control component 102 includes a slide rail 1021 with a lower opening 1022 at its center. A sliding plate 1024 is slidably connected to the slide rail 1021, and the sliding plate 1024 is connected to the opening cylinder 1023. The slide rail 1021 ensures the sliding direction and stability of the sliding plate 1024, while the lower opening 1022 controls the amount of dry powder fed, making the feeding process more stable and controllable and improving the accuracy of the fabric.

[0054] The sliding plate 1024 is also provided with a sliding opening. When the sliding opening is completely aligned with the lower opening 1022, the most powder falls from the upper tank 1011 through the powder channel 1012 into the powder hopper 103. When the sliding opening is completely misaligned with the lower opening 1022, the lower opening 1022 is completely closed. At this time, the powder no longer flows to the powder hopper 103. The intermittent opening and closing of the lower opening can be achieved by controlling the opening cylinder 1023.

[0055] During operation, the dry powder is first stored in the upper tank 1011 of the powder tank 101. The powder tank 101 provides a closed and stable environment to prevent the dry powder from leaking and becoming contaminated, ensuring the quality and stability of the dry powder. The dry powder in the upper tank 1011 flows to the feeding control component 102 of the storage component 1 through two powder feeding channels 1012. The opening cylinder 1023 drives the sliding plate 1024 to slide on the slide rail 1021. When the sliding opening of the sliding plate 1024 is completely aligned with the lower opening 1022, the dry powder feeding amount is the maximum. When it is completely misaligned, the lower opening 1022 is closed, and the feeding stops. Through the precise control of the opening cylinder 1023, the lower opening 1022 is opened and closed intermittently, achieving intermittent feeding of dry powder.

[0056] The dry powder falling from the feeding control unit 102 enters the powder hopper 103. The front projection of the powder hopper 103 is trapezoidal, with the inlet being the short side and the lower opening being the long side. The lower openings of the two powder hoppers 103 overlap in the front projection, which makes the dry powder more dispersed when it falls, increases the coverage area of ​​the fabric, and avoids dead corners of the fabric.

[0057] By turning the nut 4053 of the adjusting bolt component 405 in advance, the length of the adjusting bolt body 4051 inserted into the rocking seat 401 is adjusted, thereby changing the position of the inner crossbar 503 within the rocking seat 401. The inner crossbar 503 abuts against the opening adjusting ramp 404, and the change in the insertion length of the bolt body 4051 will change the gap between the opening adjusting ramp 404 and the other side of the rocking seat 401, thereby adjusting the size of the second space channel and the amount of dry powder fed.

[0058] The eccentric roller 402 rolls on the worktable. Its eccentric design drives the swaying seat 401 to swing, so that the dry powder in the swaying seat 401 is evenly distributed on the mesh surface of the wire mesh frame during the swinging process, thus completing the uniform distribution of dry powder.

[0059] This invention achieves uniform fabric distribution by setting up a fabric distribution mechanism 4. The swaying seat 401 of the fabric distribution mechanism 4 is connected to an eccentric roller 402. When the eccentric roller 402 rolls, it drives the swaying seat 401 to sway, which can evenly distribute the dry powder on the mesh surface of the wire mesh frame, effectively avoiding the accumulation of dry powder and ensuring uniform fabric distribution.

[0060] The powder hopper 103 has a trapezoidal shape in its front projection, with the inlet being the short side and the lower opening being the long side. Furthermore, the lower openings of the two powder hoppers 103 overlap in their front projection. This design allows the dry powder to fall more dispersedly, increasing the coverage area of ​​the fabric, avoiding dead corners, and improving the coverage and uniformity of the dry powder application.

[0061] By adjusting the bolt component 405, the position of the inner crossbar 503 within the rocking seat 401 can be changed, thereby pushing the opening adjustment ramp 404 to adjust the size of the second space channel, achieving flexible adjustment of the amount of powder applied, and accurately controlling the amount of powder applied according to different production needs.

[0062] Finally, it should be noted that the above are merely preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
