Description

Technical Field

[0001] The invention relates to the technical field of screen printing, in particular to a multi-directional adjustable screen printing clamping device. Background Art

[0002] Screen printing is essentially pore printing, which transfers patterns through the partial penetration of ink through the screen. Its core processes include screen production, ink mixing, and printing equipment. Modern technology integrates digitization, automation, and intelligence, driving its development towards high precision, multi-functionality, and environmental protection. It is widely used in electronics, textiles, glass decoration and other fields.

[0003] When existing screen printing equipment processes fabrics, the lint and fibers that fall off the surface of the fabric easily stick to the screen and mix into the ink, resulting in printing quality problems. Continuous processing is prone to screen blockage. The lint blocks the mesh and hinders the flow of ink, causing ink shortages and broken lines in the pattern. In addition, the lint adheres to the bottom surface of the screen, contaminating non-image areas during printing and producing excess ink dots. As a result, frequent shutdowns are required to clean the screen during subsequent processing, which reduces efficiency and increases waste. To this end, we propose a multi-directional adjustable screen printing clamping device to solve the above problems. Summary of the Invention

A number of feed shafts are connected to the inside of the leveling frame, and the feed shaft is rotatably arranged at the bottom of the rotating shaft. The rotating shaft can rotate when it reciprocates inside the sealing shaft.

[0020] 2. The present invention uses an auxiliary pressing block combined with an elastic pad design to provide flexible contact when limiting the position of the fabric. Compared with hard pressing blocks, this significantly reduces the risk of leaving indentations or damage on the fabric surface, effectively avoiding the subsequent additional ironing process caused by indentations, saving labor costs and better protecting fabrics of different materials.

[0021] 3. The present invention drives the movable end block through the pneumatic telescopic shaft, which can finely adjust the height of the leveling frame at the bottom of the transmission frame.

[0022] 4. During maintenance, the present invention drives the reset frame to pull down the stretch tube, causing air pressure changes to push the piston rod and push ring to move, driving the elastic pad to stretch back and forth, automatically shaking off dirt and debris adhering to its surface, simplifying maintenance;

[0023] 5.

[0037] See also Figures 1-10 The present invention provides a technical solution: a multi-directional adjustable screen printing clamping device, comprising:

[0039] Among them, a number of tilting frames 33 are provided on the outside of the lifting frame 3, and a transmission plate 35 is movably provided between the tilting frames 33. A sliding shaft 351 connected to the auxiliary pressure block 37 is inserted inside the transmission plate 35. A sealing shaft 43 is provided at the bottom of the transmission frame 4. A flattening frame 46 for stretching the cloth is connected to the sealing shaft 43. The flattening frame 46 is elastic. A number of dust suction pipes 45 that pass through the dust collecting box 44 are provided on both sides of the sealing shaft 43 to vacuum the cloth during the flattening process. When the cloth needs to be flattened and limited, the cloth can be laid on the top of the buffer plate 2 and cooperated with the sliding shaft 351 to follow the lifting frame 3 The auxiliary pressure block 37 is used to resist one side of the cloth, and the push rod motor 41 on one side is operated with the external equipment, which can drive the overall movement of the transmission frame 4, and adjust the height of the movable end block 421 according to the different materials of the cloth. During the transmission process, the cloth can be flattened and spread on the buffer pad 2, and the other side of the cloth can be pressed and limited by the movable pressure plate 21. During the resetting process of the transmission frame 4, in conjunction with the external air pressure equipment, a negative pressure can be formed inside the dust box 44, and the dust on the surface of the cloth can be transported to the inside of the dust box 44 along the filter tube 451, reducing the impact on subsequent printing.

[0040] like Figure 6 and Figure 7 As shown, a movable groove is provided inside the connecting frame 32, and a clamping plate 34 is connected to the inside of the movable groove. The sliding shaft 351 is movably clamped between the clamping plates 34. The outer wall of the sliding shaft 351 is provided with a hollow tube. The top of the sliding shaft 351 is provided with a stretching tube 38. The bottom of the stretching tube 38 is provided with a plurality of elastic inserts 381 that pass through the hollow tube. The bottom of the sliding shaft 351 is sleeved with a push ring 36. The top of the push ring 36 is provided with a plurality of piston rods 361 inserted into the hollow tube. During the maintenance process of completing the cleaning, the transmission plate and the leveling frame 46 can interact with each other, which can drive the reset frame 331 to move and stretch downward, and the stretching tube 38 can be deformed to cause air pressure changes inside, so that the piston rod 361 at the bottom can move, thereby playing a driving role.

[0041] like Figure 5As shown, the auxiliary pressure block 37 is arranged at the bottom of the sliding shaft 351, and a transmission groove is provided on the outside of the auxiliary pressure block 37, and an elastic pad 371 is movably provided inside the transmission groove. The two ends of the elastic pad 371 are connected to the outer wall of the push ring 36, and the elastic pad 371 inside the transmission groove can be stretched and clamped. In the process of limiting the cloth, the elastic pad 371 can be pressed against the surface of the cloth. Compared with the direct contact of the hard auxiliary pressure block 37, it can reduce the pressing of the cloth surface and reduce the subsequent ironing process to remove the indentation.

[0042] like Figure 5 、 Figure 6 and Figure 7 As shown, a set of reset frames 331 are movably mounted on the tilt frame 33. The reset frames 331 are rectangular and movably inserted at the top of the tilt frame 33. The bottom end of the reset frames 331 is clamped at the bottom of the stretch tube 38. The reset frames 331 are used to pull the stretch tube 38 to change its internal air pressure.

[0043] A plurality of clamping shafts are provided at the top of the reset frame 331, and a transmission plate can be clamped inside the clamping shaft. During the movement of the transmission frame 4, the leveling frame 46 at the lower end can be against the transmission plate, and the leveling frame 46 can be intermittently moved to promote the transmission of the feed shaft 461 and the rotating shaft 462. As the stretching tube 38 at the top is deformed, the air pressure changes continuously, causing the piston rod 361 at the bottom to move. At this time, the push ring 36 is reset upward, which can stretch the elastic pad 371 at the bottom. During the reciprocating process, dirt and debris adhering to the bottom are dropped, making it convenient for the operator to clean and maintain at the same time.

[0044] like Figure 8 As shown, the docking plates 42 are all provided with movable end blocks 421, and a group of pneumatic telescopic shafts are provided at the rear end of the transmission frame 4, and the pneumatic telescopic shafts are respectively connected to the inside of the movable end blocks 421 at both ends, and the movable end blocks 421 are provided with air injection holes for driving the pneumatic telescopic shafts. In the process of leveling different fabrics, the position of the movable end blocks 421 can be adjusted according to actual conditions, and the height of the leveling frame 46 can be adjusted to cope with fabrics of different materials and thicknesses, thereby reducing wear and tear during subsequent processing.

[0045] like Figure 10As shown, the dust collecting box 44 is respectively equipped with a dust suction pipe 441 and a dust collecting suction pipe 442. The dust suction pipe 441 and the dust collecting suction pipe 442 are both provided with an air injection pipe connected to an external device. The top of the dust collecting box 44 is provided with a plurality of circular grooves for clamping a sealing cover plate 48. The bottom of the sealing cover plate 48 is rotatably provided with a dust collecting pipe 47. The bottom of the inner wall of the dust collecting pipe 47 is provided with a rubber plate. The sealing cover plate 48 is provided with a circular hole that passes through the dust collecting pipe 47 and the dust collecting suction pipe 442. The dust collecting box 44 is provided with a plurality of circular grooves for clamping a sealing cover plate 48. The suction pipe 441 is connected to the dust collection box 44, and a sponge shaft is inserted into the dust suction pipe 441. When the surface of the fabric needs to be vacuumed, the external air pressure device forms a negative pressure at the dust suction pipe 441, which allows the dust to flow into the dust collection box 44 along the suction pipe 45, thereby storing dust and debris inside the dust collection box 44, reducing the possibility of blockage. In addition, the sponge shaft can also reduce the possibility of dust entering the dust suction pipe 441 and causing blockage.

[0046] A rotating shaft 462 is inserted into the sealing shaft 43, and the rotating shaft 462 passes through the sealing shaft 43 and the transmission frame 4 and is connected to the rubber plate at the bottom of the dust collecting tube 47. A number of feed shafts 461 are connected to the inside of the leveling frame 46, and the feed shaft 461 is rotatably set at the bottom of the rotating shaft 462. The rotating shaft 462 can rotate when it reciprocates inside the sealing shaft 43. When it is necessary to collect and clean the dust inside the dust collecting box 44, as the transmission frame 4 is reset, the push rod motor 41 and the pneumatic telescopic shaft are reset, and the bottom end of the leveling frame 46 can be located on the tilting frame 33, and at this time the movable end block 421 can also be synchronously displaced upward on the docking plate 42. During the transmission process, the leveling frame 46 at the bottom can be squeezed against the transmission sheet, which can It can drive the elastic material leveling frame 46 to shrink and deform, and can drive the feed shaft 461 and the rotating shaft 462 to move, thereby driving the dust collecting tube 47 at the top to move back and forth in a circular motion under the cooperation of the rotating shaft 462, and the external air pressure equipment at this time can be connected with the dust collecting suction tube 442, so that the dust can be collected on the outer wall of the dust collecting tube 47, and in the reciprocating circular motion of the dust collecting tube 47, the external adsorption shaft 471 can be swung outward to assist in the collection of floating dust, and after the adsorption shaft 471 is reset, the dust on the outside of the dust collecting tube 47 can be compacted. In the subsequent successful cleaning, most of the dust is gathered on the outside of the dust collecting tube 47, and the dust collecting tube 47 can be directly flushed for maintenance.

[0047] like Figure 10 As shown, an annular groove is provided on the outer wall of the dust collecting tube 47, and several groups of adsorption shafts 471 are provided inside the annular groove. The adsorption shafts 471 are arc-shaped and are evenly arranged in an array inside the annular groove. Several air inlet grooves are provided on the outer wall of the dust collecting tube 47. A sponge shaft can be inserted into the dust collecting tube 47. Under the action of the sponge shaft, the dust entering the dust collecting suction tube 442 can be reduced, and the sponge shaft can be replaced and maintained regularly to reduce blockage.

[0048] like Figure 9 As shown, a filter insert 451 is inserted into the dust suction tube 45, and a metal mesh plate is provided at the bottom of the filter insert 451. The air flow can enter the dust collection box 44 along the filter insert 451. The metal mesh plate can play a blocking role, reducing large pieces of cloth debris from being blocked in the filter insert 451.

[0049] like Figure 2 and Figure 3 As shown, a movable pressing plate 21 is provided on the top of the buffer pad 2. The height of the movable pressing plate 21 can be adjusted to limit the cloth. The cloth can be pressed and limited to facilitate subsequent printing processing.

[0050] Working principle: First, when the cloth needs to be leveled and limited, the cloth can be laid on the top of the buffer pad 2, and the sliding shaft 351 can follow the movement of the lifting frame 3, and the auxiliary pressure block 37 can be used to resist one side of the cloth, and the push rod motor 41 on one side and the external equipment can be operated to drive the transmission frame 4 to move as a whole, and the height of the movable end block 421 can be adjusted according to the cloth of different materials. During the transmission process, the cloth can be pushed and spread on the buffer pad 2, and the other side of the cloth can be pressed and limited by the movable pressure plate 21. During the resetting process of the transmission frame 4, the external air pressure equipment can form a negative pressure inside the dust collection box 44, and the dust on the surface of the cloth can be transported to the inside of the dust collection box 44 along the filter insert 451, reducing the impact on subsequent printing, and during the dust collection process, the airflow of the external air pressure equipment can flow along the inside of the dust suction pipe 441, which can gather dust and the like inside the dust collection box 44, and cooperate with the effect of the sponge shaft to reduce the blockage of the dust suction pipe 441.

[0051] Then, after the printing of the cloth is completed, the movable pressing plate 21 and the lifting frame 3 can be lifted up a certain distance, and the cloth can be taken out. As the transmission frame 4 is reset, the push rod motor 41 and the air pressure telescopic shaft are reset, and the bottom end of the leveling frame 46 can be located on the tilting frame 33, and at this time, the movable end block 421 can also be synchronously displaced upward on the docking plate 42. During the transmission process, the leveling frame 46 at the bottom can be squeezed against the transmission plate, which can drive the elastic material leveling frame 46 to shrink and deform, and can drive the feed shaft 461 and the rotating shaft 462 to move, thereby driving the dust collecting pipe 47 at the top to reciprocate in a circular motion under the cooperation of the rotating shaft 462, and as the external air pressure equipment and the dust collecting suction pipe 442 are connected, dust can be accumulated on the outer wall of the dust collecting pipe 47 along the air flow. During the reciprocating motion, the adsorption shaft 471 can swing outward to squeeze the dust and the like and accumulate them on the outer wall of the dust collecting pipe 47, which is convenient for subsequent unified cleaning and maintenance.

[0052] Finally, during the interaction between the transmission plate and the leveling frame 46, the reset frame 331 can be driven to move and stretch downward, which can cause the stretching tube 38 to deform and cause the air pressure change inside, so that the piston rod 361 at the bottom can move. At this time, the push ring 36 is reset upward, which can stretch the elastic pad 371 at the bottom. In the reciprocating process, the dirt and debris adhering to the bottom fall off, making it convenient for the operator to clean and maintain at the same time.

[0053] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
