Description

Technical Field

[0001] This utility model belongs to the field of screen printing machines, specifically relating to a screen printing machine that facilitates the installation of screen plates. Background Technology

[0002] A screen printing machine, also known as a silkscreen printing press, is a device that uses a silkscreen plate as a printing plate base. It creates a screen printing plate with images and text using a photosensitive method, and then uses a squeegee to force ink through the mesh of the screen printing plate onto the surface of the substrate, thus achieving the printing of images and text. It has advantages such as strong printing adaptability, thick ink layer, strong three-dimensional effect, and low cost, and is widely used in many industries including electronics, packaging, advertising, ceramics, textiles, and glass.

[0003] When using a screen printing machine, the printing plate is placed on the suction plate. Then, the negative pressure device uses micropores to suction and position the plate on the surface of the suction plate. Next, the position of the screen is adjusted and moved to the upper surface of the printing plate. Then, the squeegee moves on the screen at a certain angle and pressure, squeezing the ink through the mesh onto the surface of the substrate, thus printing patterns and text on the surface of the printing plate.

[0004] In practice, the installation of the screen printing stencil presents significant drawbacks when the machine is put into use. During installation, workers must manually rotate multiple bolts sequentially to achieve a secure fit. Due to the large number of bolts, and the fact that each bolt needs to be tightened individually, the entire process is cumbersome and tedious, making installation extremely inefficient and impacting overall production progress.

[0005] In view of this, the present invention provides a screen printing machine that facilitates the installation of stencils to solve the problem of low stencil installation efficiency. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screen printing machine that facilitates the installation of a stencil, comprising:

[0007] The screen printing machine assembly includes a screen printing machine cabinet located at the bottom, a controller installed on the side surface of the screen printing machine cabinet, a sliding base installed on the top of the screen printing machine cabinet, support arms slidably connected to the side surface of the sliding base and symmetrically arranged, a doctor blade slidably connected to the side surface of the sliding base, an adsorption plate installed on the upper surface of the screen printing machine cabinet, and a screen plate connected between the support arms.

[0008] The fixing assembly includes a fixing housing connected to the side surface of the support arm, a fixing part installed on the inner wall of the fixing housing and extending to the upper surface, and a first guide part disposed between the fixing housing and the mesh plate;

[0009] The material handling assembly includes a tray fitted into the center of the adsorption plate, a telescopic rod connected to the lower surface of the tray and mounted on the upper surface of the screen printing machine cabinet, and a second guide part connected to both sides of the tray and connected to the upper surface of the screen printing machine cabinet.

[0010] As a preferred embodiment of the present invention, a screen printing machine for easy installation of a screen plate, the fixing part includes two sets of positioning posts that penetrate the surface of the horizontal plate inside the fixing housing and are symmetrically arranged, a horizontal plate connected to the top of the two positioning posts, a threaded sleeve that penetrates and is connected to the middle of the horizontal plate, a screw rod that penetrates the inside of the threaded sleeve and is adapted to it, and a bearing that is sleeved on the screw rod and fitted onto the upper surface of the fixing housing.

[0011] As a preferred embodiment of the present invention, which facilitates the installation of a screen printing machine, the fixing part further includes a pressure plate connected to the surface of the positioning post, a rubber pad connected to the lower surface of the pressure plate, and positioning holes opened on the surface of the screen and corresponding one-to-one with the positioning posts and adapted in size.

[0012] As a preferred embodiment of the present invention, which facilitates the installation of a screen printing machine, the first guide portion includes a guide groove formed on the bottom surface of the screen and a column connected to the inner wall of the fixed housing and matching the size of the guide groove.

[0013] As a preferred embodiment of the present invention, the second guide portion includes side ears connected to both sides of the tray, a guide tube that penetrates and connects to the horizontal surface of the side ears, and a guide rod that penetrates the guide tube and connects to the lower surface of the adsorption plate.

[0014] As a preferred embodiment of the present invention, a screen printing machine that facilitates the installation of a screen plate, wherein the telescopic rod drives the tray to move axially, and when the telescopic rod drives the tray to the lowest point of its stroke, the upper surface of the tray is flush with the upper surface of the adsorption plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention uses a mesh plate to guide the guide groove to slide on the surface of the column to the farthest end of its travel, and then rotates the screw. When the screw rotates, it drives the screw sleeve to move downward. The downward movement of the screw sleeve drives the positioning column to move downward through the horizontal plate. When the positioning column moves downward to the inside of the positioning hole and is pressed against the surface of the mesh plate by the pressure plate, the mesh plate can be quickly and easily fixed.

[0017] This invention uses a telescopic rod to extend and move the pallet upwards, which in turn moves the supporting plate upwards, thus enabling rapid removal of the supporting plate and preventing it from being too thin and sticking to the surface of the adsorption plate, making it difficult to remove.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] This utility model relates to a screen printing machine that facilitates the installation of the stencil, such as... Figures 1-6 As shown, it includes:

[0029] The screen printing machine assembly 100 includes a screen printing machine cabinet 101 located at the bottom, a controller 102 mounted on the side surface of the screen printing machine cabinet 101, a sliding base 103 mounted on the top of the screen printing machine cabinet 101, support arms 104 slidably connected to the side surface of the sliding base 103 and symmetrically arranged, a doctor blade 105 slidably connected to the side surface of the sliding base 103, an adsorption plate 106 mounted on the upper surface of the screen printing machine cabinet 101, and a screen plate 107 connected between the support arms 104.

[0030] The fixing assembly 200 includes a fixing housing 201 connected to the side surface of the support arm 104, a fixing part 202 installed on the inner wall of the fixing housing 201 and extending to the upper surface, and a first guide part 203 disposed between the fixing housing 201 and the mesh plate 107.

[0031] The fixing part 202 includes two sets of positioning posts 202a symmetrically arranged, penetrating the surface of the inner wall of the fixing housing 201; a horizontal plate 202b connected to the top of the two positioning posts 202a; a threaded sleeve 202c penetrating and connected to the middle of the horizontal plate 202b; a screw 202d penetrating the inside of the threaded sleeve 202c and adapted to it; and a bearing 202e sleeved on the screw 202d and fitted onto the upper surface of the fixing housing 201. When the screw 202d rotates inside the bearing 202e, it can drive the threaded sleeve 202c to move downward through the threaded connection. The downward movement of the threaded sleeve 202c can drive the horizontal plate 202b to move downward, and the downward movement of the horizontal plate 202b can drive the positioning posts 202a to move downward, thereby adjusting the height of the positioning posts 202a.

[0032] Furthermore, the fixing part 202 also includes a pressure plate 202f connected to the surface of the positioning post 202a, a rubber pad 202g connected to the lower surface of the pressure plate 202f, and positioning holes 202h formed on the surface of the mesh plate 107 that correspond one-to-one with the positioning posts 202a and are adapted in size. When the positioning post 202a moves downward into the interior of the positioning hole 202h on the surface of the mesh plate 107, and the positioning post 202a drives the rubber pad 202g to press against the surface of the mesh plate 107 through the pressure plate 202f, the position of the mesh plate 107 can be fixed at this time.

[0033] Furthermore, the first guide section 203 includes a guide groove 203a formed on the bottom surface of the mesh plate 107 and a column 203b connected to the inner wall of the fixed housing 201 and matching the size of the guide groove 203a. When the mesh plate 107 is installed, it is first inserted into the inner wall of the fixed housing 201 and drives the guide groove 203a to slide on the surface of the column 203b. When the mesh plate 107 drives the guide groove 203a to slide to the farthest end of its travel on the surface of the column 203b, the positioning hole 202h is located directly below the positioning column 202a.

[0034] When using the mesh plate 107, first insert the mesh plate 107 into the inner wall of the fixed housing 201 and drive the guide groove 203a to slide on the surface of the column 203b to the farthest end of the stroke. At this time, the positioning hole 202h is located directly below the positioning column 202a. Then, the screw 202d can be rotated. When the screw 202d rotates, it drives the screw sleeve 202c to move downward. The downward movement of the screw sleeve 202c drives the positioning column 202a to move downward through the horizontal plate 202b. When the positioning column 202a moves downward into the interior of the positioning hole 202h and is pressed against the surface of the mesh plate 107 by the pressure plate 202f and the rubber pad 202g, the position of the mesh plate 107 can be fixed.

[0035] Example 2

[0036] like Figures 5-6 The second embodiment of the present invention is shown, which differs from the first embodiment in that: the material handling component 300 includes a tray 301 fitted into the center of the adsorption plate 106, a telescopic rod 302 connected to the lower surface of the tray 301 and installed on the upper surface of the screen printing machine cabinet 101, and a second guide part 303 connected to both sides of the tray 301 and connected to the upper surface of the screen printing machine cabinet 101.

[0037] The second guide section 303 includes side ears 303a connected to both sides of the tray 301, a guide cylinder 303b extending through and connected to the horizontal surface of the side ears 303a, and a guide rod 303c extending through the guide cylinder 303b and connected to the lower surface of the adsorption plate 106. When the tray 301 is subjected to a force, it can drive the side ears 303a to move longitudinally. When the side ears 303a move longitudinally, it can drive the guide cylinder 303b to slide on the surface of the guide rod 303c, thereby limiting the movement direction of the tray 301 while maintaining the stability of the movement of the tray 301.

[0038] Furthermore, the telescopic rod 302 drives the pallet 301 to move axially. When the telescopic rod 302 drives the pallet 301 to the lowest end of its stroke, the upper surface of the pallet 301 is flush with the upper surface of the adsorption plate 106.

[0039] In use, the carrier plate is first placed in the center of the adsorption plate 106 and above the support plate 301. Then, the position of the screen plate 107 is adjusted so that it is on the surface of the carrier plate. Then, the negative pressure device adsorbs the carrier plate onto the surface of the adsorption plate 106 and the support plate 301 through the micropores. Then, ink is poured into the screen plate 107. Then, the ink is pressed onto the surface of the carrier plate through the mesh by the ink scraper 105, thereby realizing printing.

[0040] After printing is completed, the telescopic rod 302 can be operated. When the telescopic rod 302 extends, it can drive the pallet 301 to move upward. The upward movement of the pallet 301 can drive the guide cylinder 303b to slide on the surface of the guide rod 303c through the side ear 303a. The upward movement of the pallet 301 can drive the supporting plate to move upward, thereby realizing the rapid picking up of the supporting plate.

[0041] It should be noted that micropores are provided on the surfaces of both the adsorption plate 106 and the support plate 301, which allows the thin plate to be adsorbed onto the surfaces of the adsorption plate 106 and the support plate 301 by the suction force generated by the negative pressure device, thereby fixing the position of the thin plate.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
