Description

Technical Field

[0001] The utility model relates to the field of printing machines, in particular to an auxiliary feeding mechanism of a flat-net curved-surface screen printing machine. Background Art

[0002] A screen printer is a machine that uses a screen printing plate to print, and is a type of printing press. A screen printer is a machine that prints text and images, and is a general term for machines or equipment used to produce printed products. A screen printer is a more representative printing device among stencil printers. In addition to silk, the materials used to make the screen can also be nylon wire, copper wire, steel wire or stainless steel wire. It can be divided into flat screen printers, curved screen printers, rotary screen printers, etc. In the bottle printing industry, flat curved screen printers are often used. When in use, the bottles to be printed need to be placed one by one on the conveyor belt so that they can be transported and loaded through the conveyor belt.

[0003] The auxiliary feeding mechanism of the flat screen curved screen printer places the bottle body in a U-shaped seat on a conveyor belt, and then transports the U-shaped seat through the conveyor belt and drives the bottle body to move, so as to transport the bottle body to the bottom of the printing machine. However, after the bottle body is placed in the U-shaped seat, it is difficult to limit the bottle body, so the bottle body may rotate during the printing process, thereby affecting the printing effect of the bottle body and reducing the stability of the bottle body placed in the U-shaped seat. Utility Model Content

[0010] By adopting the above technical solution, when the active roller rotates, it will drive the transmission belt to rotate, and the driven roller will also rotate accordingly.

[0011] Furthermore, a limiting rod is provided at the bottom of the placement plate, and the bottom end of the limiting rod passes through the movable seat.

[0012] By adopting the above technical solution, the setting of the limiting rod can limit the movable seat to prevent the movable seat from rotating.

[0013] Furthermore, the movable seat is threadedly connected to the threaded column, and a knob is installed at the other end of the rotating shaft.

[0014] By adopting the above technical solution, when the threaded column rotates, it will drive the movable seat to move, and after the movable seat moves, it will pull the pull plate to rotate.

[0018] By adopting the above technical solution, the clamping plate can be easily rotated, and after the clamping plate is rotated and fits with the clamped object, the clamped object can be limited.

[0019] Furthermore, an anti-slip pad is provided on the inner wall of the clamping plate.

[0020] By adopting the above technical solution, the provision of the anti-slip pad can protect the clamped object and prevent the clamped object from being damaged due to excessive clamping force.

[0021] Furthermore, the pull plate is rotatably connected to the movable seat, and the pull plate passes through the through opening.

When it is necessary to convey and feed the printed object, the driving motor 5 can be started, and the driving motor 5 can drive the shaft active roller 6 to rotate, and then drive the conveyor belt 2 to rotate, and then drive the U-shaped seat 3 to move, so as to facilitate the conveying of the U-shaped seat 3.

[0037] See also Figure 1-Figure 5 The clamping assembly 4 includes a placement plate 404 arranged inside the U-shaped seat 3, a fixed plate 402 fixed to both sides of the U-shaped seat 3, and a rotating shaft 409 arranged on the U-shaped seat 3 through a bearing, and a driving bevel gear 408 is installed at one end of the rotating shaft 409, a threaded column 406 is connected between the placement plate 404 and the U-shaped seat 3 through a bearing, and a movable seat 410 is sleeved on the upper part of the outer wall of the threaded column 406, and a driven bevel gear 407 is installed below the outer wall of the threaded column 406, The movable seat 410 is threadedly connected to the threaded column 406. When the threaded column 406 rotates, it will drive the movable seat 410 to move. After the movable seat 410 moves, it will pull the pull plate 403 to rotate. A knob is installed at the other end of the rotating shaft 409. The setting of the knob is convenient for the user to rotate the rotating shaft 409. The active bevel gear 408 is meshed with the driven bevel gear 407. When the active bevel gear 408 rotates, it will drive the driven bevel gear 407 to rotate, and then drive the threaded column 406 to rotate.

[0038] Specifically, both sides of the top of the placement plate 404 are penetrated by through openings 405, one side of the fixed plate 402 is connected to a clamping plate 401 through a rotating shaft, and a pulling plate 403 is provided between the clamping plate 401 and the movable seat 410 through a movable shaft. When the pulling plate 403 rotates, it will pull the clamping plate 401 to rotate. After the clamping plate 401 rotates and fits the printed object, the printed object can be limited to prevent the printed object from moving randomly during the printing process and affecting the printing effect. The clamping plate 401 is rotatably connected to the fixed plate 402 to facilitate the rotation of the clamping plate 401. The clamping plate 401 is arc-shaped, and the pulling plate 403 is rotatably connected to the movable seat 410. The pulling plate 403 passes through the through opening 405, so that when the movable seat 410 moves, it will drive the pulling plate 403 to rotate, and the pulling plate 403 will pull the clamping plate 401 to rotate.

[0039] Embodiment 2:

[0040] On the basis of the above-mentioned first embodiment, since the threaded column 406 will drive the movable seat 410 to move when it rotates, in order to prevent the movable seat 410 from rotating with the threaded column 406, the movable seat 410 needs to be guided, so the following structure is set.

[0041] Specifically, a limiting rod 411 is provided at the bottom of the placement plate 404 , and the bottom end of the limiting rod 411 passes through the movable seat 410 . The setting of the limiting rod 411 can limit the movable seat 410 to prevent the movable seat 410 from rotating.

[0042] Embodiment three:

[0043] On the basis of the above-mentioned embodiment 1, in order to improve the stability of the clamped object, the following structure is provided.

[0044] See also Figure 2 and Figure 6 The inner wall of the clamping plate 401 is provided with an anti-skid pad 412. The provision of the anti-skid pad 412 can protect the clamped object and improve the stability of the clamped object to prevent the clamped object from moving.

[0045] The working principle of the utility model is as follows: first, the staff can place the bottle body in the U-shaped seat 3, and then the staff can rotate the rotating shaft 409 through the knob, the rotating shaft 409 drives the active bevel gear 408 to rotate, and then drives the driven bevel gear 407 to rotate, and drives the threaded column 406 to rotate, the threaded column 406 drives the movable seat 410 to move downward, the movable seat 410 drives the pull plate 403 to rotate, and the pull plate 403 will pull the clamping plate 401 to rotate, after the clamping plate 401 rotates and fits the printed object, the bottle body can be limited, and then the driving motor 5 can be started, the driving motor 5 drives the active roller 6 to rotate, and then drives the conveyor belt 2 to rotate, and the conveyor belt 2 can transport the bottle body. When the bottle body moves to the bottom of the printing machine, the driving motor 5 drives the active roller 6 to rotate, and then drives the conveyor belt 2 to rotate, and the conveyor belt 2 can transport the bottle body. The machine is turned off, and the conveyor belt 2 no longer transports the bottle body. A staff member can put the bottle body to be printed into the U-shaped seat 3 while the printing machine is printing the bottle body, and repeat the above steps to achieve the purpose of limiting the bottle body. Since the clamping plate 401 is rotatable, the clamping plate 401 can fit and limit the bottles of different diameters, thereby improving the applicability of the clamping assembly. Another staff member can take the printed bottle body out of the U-shaped seat 3. The taking-out process is to rotate the rotating shaft 409 in the opposite direction, so that the threaded column 406 rotates in the opposite direction, and the movable seat 410 moves up, and drives the pull plate 403 to rotate, and then drives the clamping plate 401 to return and rotate, so that the clamping plate 401 is opened and no longer fits the bottle body. At this time, the staff member can take out the printed bottle body.
