Description

Technical Field

[0001] The utility model belongs to the field of printing screens, relates to high-strength screen technology, and specifically is a high-strength aluminum frame printing screen. Background Art

[0002] Screen printing is a multi-purpose printing technology. Mainly, structures such as a squeegee are used above the screen to evenly apply materials such as ink on the screen to the surface of the material to be printed. Generally, the screen slides to the inside of the screen printing machine at a specific position and is then fixed in position by a cylinder. And the screen printing machine will use screens with different filter screen sizes to adapt to different printing requirements.

[0003] Referring to the patent name: A new type of high-strength aluminum frame printing screen (Patent Publication No.: CN219338919U), the spring between the central reinforcing frame and the outer retaining frame on the surface of the screen enables the filter screen of the screen to slide between the outer retaining frame and the outside, so that when the outer retaining frame is impacted or deformed by an external force, it can buffer the force that part of the filter screen will receive, avoiding deformation of the filter screen and affecting the subsequent use of the screen.

[0004] However, when implementing the above technical solution, there are the following problems: In the above device, the outer retaining frame is fixedly connected to the inner support frame through a reinforcing rib, and the inside of the outer retaining frame contacts the inside of the inner support frame through a rubber gasket, that is, the distance between the outer retaining frame and the inner support frame is fixed. The size of the inner support frame limits the size of the corresponding outer retaining frame. Therefore, when a certain outer retaining frame is damaged and needs to be replaced, the operator can only purchase an outer retaining frame of a specific size for replacement. That is, after the outer retaining frame is produced, its applicable range is strictly limited, reducing flexibility and increasing the use and production costs to a certain extent.

[0005] Therefore, the utility model proposes a high-strength aluminum frame printing screen. Utility Model Content

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. For this reason, the utility model proposes a high-strength aluminum frame printing screen, which solves the problem that the size of the screen that can be fixed inside the outer retaining frame for enhancing strength protection in the use of the printing screen is fixed and the application range is limited.

[0007] To achieve the above object, according to an embodiment of the first aspect of the utility model, a high-strength aluminum frame printing screen is proposed, including a protective frame and a screen. An adjusting mechanism is arranged between the protective frame and the screen. The adjusting mechanism includes:

[0008] A plurality of contact rods, and the sides of the contact rods away from the protective frame are all in contact with the screen;

[0009] A number of support rods, one end of each support rod is fixedly connected to the protective frame, the support rod is slidably connected inside the contact rod, and an acting rod is slidably connected to the surface of the support rod; an acting shaft is slidably connected inside the contact rod, the acting rod is slidably connected inside the acting shaft, and an acting spring is fixedly connected between the acting rod and the acting shaft;

[0010] A number of knotting components, the knotting components are slidably arranged between the acting rod and the support rod, the acting rod and the acting shaft, and the acting shaft and the contact rod; the knotting components are used to realize the conversion between synchronous movement and independent movement of two structures.

[0011] Optionally, the knotting component includes a sliding block, a number of knotting teeth and a driving block. A triangular block is fixedly connected to one side of the sliding block close to the knotting teeth, and the triangular block is adapted to the knotting teeth.

[0012] Optionally, an arc-shaped groove is provided in the middle of the driving block at the position of the acting rod close to the support rod, and the arc on the surface of the arc-shaped groove and the other driving blocks is located on the same horizontal plane.

[0013] Optionally, one side of the sliding block close to the driving block is arc-shaped, and a knotting spring is fixedly connected to one side of the sliding block close to the driving block.

[0014] Optionally, a passive block is slidably connected inside the contact rod, the driving block is slidably connected to the passive block, and a moving rod is slidably connected inside the protective frame.

[0015] Optionally, a moving shaft is fixedly connected to the acting rod on the side close to the support rod, a moving groove is provided on the surface of the support rod, and the moving shaft is slidably connected to the moving groove.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: The distance between the protective frame and the screen plate can be flexibly adjusted through the contact rod and the support rod that slide between the protective frame and the screen plate. Thus, screen plates of various sizes can be placed inside the protective frame. Moreover, a sliding acting shaft and acting rod are provided between the contact rod and the support rod. The positions among the support rod, the acting rod, the contact rod and the acting shaft can all be changed by the knotting components. An acting spring is provided between the acting rod and the acting shaft. That is, in the unused state, the distance between them is constant. When the support rod and the acting rod are fixed in position with the contact rod and the support rod, and the acting rod and the acting shaft slide, and the protective frame is impacted, the acting rod will slide inside the acting shaft. Thus, the force is buffered by the acting spring to prevent the screen plate in contact with the contact rod from being damaged. Therefore, through the above structure, screen plates of different sizes can be fixed inside the protective frame and the protective frame can protect the screen plate, increasing the service strength of the screen plate.

[0029] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] As Figures 1-7 shown, a high-strength aluminum frame printing screen plate includes a protection frame 1 and a screen plate 2, and an adjustment mechanism is provided between the protection frame 1 and the screen plate 2. The adjustment mechanism includes:

[0031] a plurality of contact rods 31, and the sides of the contact rods 31 away from the protection frame 1 are all in contact with the screen plate 2;

[0032] A number of support rods 32, one end of each of the support rods 32 is fixedly connected to the protective frame 1, the support rods 32 are slidably connected inside the contact rod 31, and an actuating rod 33 is slidably connected to the surface of the support rods 32; an actuating shaft 34 is slidably connected inside the contact rod 31, the actuating rod 33 is slidably connected inside the actuating shaft 34, and an actuating spring 35 is fixedly connected between the actuating rod 33 and the actuating shaft 34;

[0033] It should be noted that one contact rod 31 and one support rod 32 in a number of contact rods 31 (only one is drawn in the figure) and a number of support rods 32 (only one is drawn in the figure) form a group, and the two are slidably connected. An elastic ring (not shown in the figure) is fixedly connected between single groups. When the contact rod 31 or the support rod 32 in a single group moves, the corresponding structures in other groups can be synchronously driven to move through the elastic ring (not shown in the figure);

[0034] A number of knotting components, the knotting components are slidably arranged between the actuating rod 33 and the support rod 32, between the actuating rod 33 and the actuating shaft 34, and between the actuating shaft 34 and the contact rod 31; the knotting components are used to realize the conversion between synchronous movement and independent movement of two structures;

[0035] In the actual application process of this high-strength aluminum frame printing screen plate 2, the distance between the protective frame 1 and the screen plate 2 can be flexibly adjusted through the contact rod 31 and the support rod 32 that slide between them. Thus, screen plates 2 of various sizes can be placed inside the protective frame 1. And a sliding actuating shaft 34 and actuating rod 33 are arranged between the contact rod 31 and the support rod 32. The positions among the support rod 32, the actuating rod 33, the contact rod 31, and the actuating shaft 34 can all be changed through the knotting components. And an actuating spring 35 is arranged between the actuating rod 33 and the actuating shaft 34. That is, in the unused state, the distance between them is constant. When the support rod 32 and the actuating rod 33 are fixed in position with the contact rod 31 and the support rod 32, and the actuating rod 33 and the actuating shaft 34 slide, when the protective frame 1 is impacted, the actuating rod 33 will slide inside the actuating shaft 34. Thus, the force is buffered through the actuating spring 35 to prevent the screen plate 2 in contact with the contact rod 31 from being damaged. Thus, through the above structure, screen plates 2 of different sizes can be fixed inside the protective frame 1 and the protective frame 1 can protect the screen plate 2, increasing the service strength of the screen plate 2;

[0036] In some specific implementation schemes, the above-mentioned knotting components include a sliding block 41, a number of knotting teeth 42, and a driving block 43. A triangular block 44 is fixedly connected to one side of the sliding block 41 close to the knotting teeth 42. The triangular block 44 is adapted to the knotting teeth 42. One side of the sliding block 41 close to the driving block 43 is arc-shaped, and a knotting spring 45 is fixedly connected to one side of the sliding block 41 close to the driving block 43;

[0037] The other end of the clamping spring 45 between the acting rod 33 and the supporting rod 32 is fixedly connected to the inside of the acting rod 33, and the sliding block 41 is slidably connected to the acting rod 33; the sliding block 41 between the acting rod 33 and the acting shaft 34 is slidably connected to the inside of the acting rod 33, and the other end of the clamping spring 45 is fixedly connected to the inside of the acting rod 33; the sliding block 41 between the acting shaft 34 and the contact rod 31 is slidably connected to the inside of the acting shaft 34, and the other end of the clamping spring 45 is fixedly connected to the inside of the acting shaft 34;

[0038] In a further embodiment, a passive block 51 is slidably connected inside the contact rod 31, the driving block 43 is slidably connected to the passive block 51, and a moving rod 52 is slidably connected inside the protective frame 1; the moving rod 52 moves on the comb-shaped track of the protective frame 1, moves horizontally at a lower position, and the vertical grooves at a higher position and a lower position are threadedly connected to the moving rod 52. Therefore, when the moving rod 52 is at the upper position of the protective frame 1, its position will be fixed under the action of the thread, and when the moving rod 52 moves downward, it will drive the passive rod to move downward at the same time;

[0039] In a further embodiment, the driving block 43 on the acting rod 33 near the supporting rod 32 is different from the other two driving blocks 43. An arc-shaped groove is also provided in the middle of the driving block 43 on the acting rod 33 near the supporting rod 32, and the arc-shaped groove at this position and the arcs on the surfaces of the other driving blocks 43 are on the same horizontal plane;

[0040] In some specific embodiments, a moving shaft 61 is fixedly connected to one side of the acting rod 33 near the supporting rod 32, a moving groove 62 is formed on the surface of the supporting rod 32, and the moving shaft 61 is slidably connected to the moving groove 62;

[0041] The working principle of the present invention: When adjusting the position of the contact rod 31 inside the protective frame 1, first move the moving rod 52 downward. The movement of the moving rod 52 causes the passive block 51 to move downward. The downward movement of the passive block 51 drives the driving block 43 to slide. The sliding of the driving block 43 will cause the three sliding blocks 41 to move simultaneously. The sliding block 41 that slides from the inside of the acting rod 33 towards the supporting rod 32 moves towards the driving block 43, and the sliding blocks 41 that move from the inside of the acting rod 33 towards the acting shaft 34 and from the inside of the acting shaft 34 towards the inside of the contact rod 31 slide away from the driving block 43. At this time, the triangular block 44 and the clamping teeth 42 come into contact, and at this time, the positions of the acting rod 33, the acting shaft 34, and the contact rod 31 are fixed. Then, pull the moving rod 52. The pulling of the moving rod 52 causes the contact rod 31 to move away from or close to the inner wall of the protective frame 1. After the position of the contact rod 31 is appropriate, move the moving rod 52 upward, and the position of the moving rod 52 is fixed, and then clamp the screen plate 2 between the contact rods 31;

[0042] When the protective frame 1 is subjected to an external force, the acting rod 33 will slide inside the acting shaft 34 and continuously buffer the force received under the action of the acting spring 35.

[0043] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
