In addition, it should be noted that the specification describes many features. Although certain features can be combined together to show possible system designs, these features can also be used in other combinations that are not explicitly described. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0030] The principles of the present application will be described in detail below with reference to the drawings and examples.

[0031] The present application provides a feeding plate material belt limiting mechanism of a screen printing machine, which comprises a bar plate 1, the bar plate 1 is provided with a mounting groove 2 along the long direction, a pair of position limiting assemblies 3 are arranged in the mounting groove 2, and each position limiting assembly 3 is provided with a position limiting bearing 4 for blocking the material belt of the screen printing machine at one end opposite to the other position limiting assembly. The bar plate 1 is embedded on the feeding plate of the screen printing machine, the metal material belt passes through the pair of position limiting assemblies 3 and then enters the screen printing machine, and the position limiting bearing 4 is used for limiting and guiding the metal material belt ready for screen printing. Since the position limiting bearing 4 can roll, the friction between the position limiting bearing 4 and the metal material belt is reduced after the position limiting bearing 4 replaces the fixed blocking block in the background technology, and the material belt edge curling is avoided.

[0032] In the embodiment, the limiting assembly 3 further comprises a sliding block 31, a carrier plate 32 and a cover plate 33. The sliding block 31 is slidingly arranged in the mounting groove 2. The carrier plate 32 is detachably arranged on the top of the sliding block 31, and the top surface of the carrier plate 32 is flush with the top surface of the strip-shaped plate 1. The cover plate 33 is detachably arranged on the top of the carrier plate 32. The limiting bearing 4 is arranged between the carrier plate 32 and the cover plate 33. One side of the metal strip in the width direction of the silk-screen printing machine is limited between the side notch 34 composed of the cover plate 33, the carrier plate 32 and the limiting bearing 4. The metal strip is advanced at a fixed frequency, and the metal strip is relatively strong in elasticity and is easy to jump out of the limiting range of the limiting assembly 3 when being pulled. The side notch 34 can block the metal strip from above.

[0033] In the embodiment, the limiting assembly 3 is provided with a spacing adjustment mechanism for adjusting the height of the side notch 34. The height of the side notch 34 is adjusted by adjusting the spacing between the cover plate 33 and the carrier plate 32, so as to adapt to metal strips of different thicknesses.

[0034] The cover plate 33 is provided with a first countersunk hole 331. The blind hole of the first countersunk hole 331 is opposite to the top of the limiting bearing 4, and is used for accommodating the limiting bearing 4 when the height of the side notch 34 is adjusted. The top of the carrier plate 32 is fixedly provided with a shaft rod 321. The top end of the shaft rod 321 is sleeved in the through hole of the first countersunk hole 331. The inner ring of the limiting bearing 4 is sleeved on the outside of the shaft rod 321. The inner ring of the limiting bearing 4 is provided with a stop groove 41. The periphery of the shaft rod 321 is provided with a stop key 322 matched with the stop groove 41. The cover plate 33 and the carrier plate 32 are locked and fixed with the sliding block 31 by a locking screw 5. The carrier plate 32 is provided with a through hole 323 penetrating the shaft rod 321 and the body of the carrier plate 32. The sliding block 31 is provided with a locking screw hole 311. The shank of the locking screw 5 is passed through the through hole 323 and is screwed in the locking screw hole 311. The spacing adjustment mechanism comprises an adjusting screw 6, a sleeve 7, a second countersunk hole 332 and a positioning screw hole 324. The second countersunk hole 332 is formed in the cover plate 33. The front end of the sleeve 7 is provided with an external thread. The rear end of the sleeve 7 is provided with a sleeve head 71 engraved with a screw groove. The sleeve 7 is inverted in the second countersunk hole 332, and the front end of the sleeve 7 is protruded from the through hole of the second countersunk hole 332. The head of the adjusting screw 6 is provided with an annular groove 61. The outer ring groove wall of the annular groove 61 is provided with an inner thread matched with the external thread. The end of the sleeve 7 provided with the external thread is inserted into the annular groove 61 and is screwed and fixed with the adjusting screw 6. The positioning screw hole 324 is formed in the carrier plate 32. The front end of the adjusting screw 6 is screwed in the positioning screw hole 324 through the sleeve 7.

[0035] When assembled, the sleeve 7 is first inverted into the second countersunk hole 332 from the bottom of the cover plate 33, and then the adjusting screw 6 is inserted into the sleeve 7, and the sleeve 7 is screwed with the screwdriver to align the screw slot, so that the sleeve 7 is tightly connected with the adjusting screw 6 to avoid loosening. Since the sleeve 7 can freely rotate in the second countersunk hole 332, after the adjusting screw 6 is screwed into the positioning hole, the height of the cover plate 33 can be changed by rotating the adjusting screw 6, thereby playing a role in adjusting the height of the side notch 34. When the side notch 34 is adjusted, the cover plate 33, the carrier plate 32 and the slider 31 are fixedly connected by tightening the locking screw 5, and at the same time, the adjusting screw 6 is prevented from loosening.

[0036] In the embodiment, the slider 31 is provided with a transmission threaded hole 312, and the installation groove 2 is provided with a screw rod 8 in transmission cooperation with the transmission threaded hole 312. The installation groove 2 is open at one end, and the opening is detachably provided with a sealing plate 9. After the sealing plate 9 is removed, the screw rod 8 and the limiting assembly 3 can be removed from the installation groove 2. One end of the screw rod 8 is connected with a knob 81 through the sealing plate 9. By rotating the knob 81, the spacing of a pair of limiting assemblies 3 can be adjusted to adapt to metal strips of different widths.

[0037] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
