Description

Technical Field

[0001] This invention relates to the field of screen printing technology, specifically to a multi-directional adjustable screen printing clamping device. Background Technology

[0002] Screen printing is essentially a stencil printing process that transfers patterns by allowing ink to pass through specific areas of a screen. Its core processes include screen making, ink preparation, and printing equipment. Modern technology has integrated digitalization, automation, and intelligence, driving its development towards high precision, multi-functionality, and environmental friendliness. It is widely used in fields such as electronics, textiles, and glass decoration.

[0003] Existing screen printing equipment often suffers from problems when processing fabrics. Wool and fibers detached from the fabric surface can easily stick to the screen and mix with ink, leading to printing quality issues. Continuous processing can cause screen clogging, with lint blocking the mesh and hindering ink flow, resulting in ink gaps and broken lines in the pattern. Furthermore, lint adhering to the bottom of the screen contaminates non-image areas during printing, creating excess ink dots. This necessitates frequent shutdowns for screen cleaning in subsequent processes, reducing efficiency and increasing waste. Therefore, we propose a multi-directional adjustable screen printing clamping device to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-directional adjustable screen printing clamping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-directional adjustable screen printing clamping device, comprising,

[0006] The operating table has a fixed base plate at its top for connecting to a transmission slide rail. A buffer pad is installed on the top of the transmission slide rail. A lifting frame is provided on one side of the top of the buffer pad. A set of connecting seats is provided on one side of the buffer pad. A rotating shaft with a guide rail plate is rotatably connected between the connecting seats. The lifting frame is movably locked onto the guide rail plate. Push rod motors are provided on both sides of the lifting frame. A docking plate is provided on the output end of the push rod motor. A transmission frame is provided on the outer side of a pair of docking plates. A dust collection box is provided at the top of the transmission frame.

[0007] The lifting frame includes several inclined frames on its outer side, with a transmission plate movably mounted between them. A sliding shaft connecting to an auxiliary pressure block is inserted inside the transmission plate. A sealing shaft is located at the bottom of the transmission frame, and a fabric-flattening frame is connected to the sealing shaft. The flattening frame is elastic. Several suction pipes communicating with a dust collection box are located on both sides of the sealing shaft for vacuuming the fabric during the flattening process. When the fabric needs to be flattened and limited, it can be laid on top of a buffer pad, cooperating with the sliding shaft to move along with the lifting frame. The system moves by using an auxiliary pressure block to press against one side of the fabric, while a push rod motor on one side operates in conjunction with external equipment, driving the entire transmission frame to move. The height of the movable end block can be adjusted according to different fabric materials. During transmission, the fabric can be flattened and laid out on the buffer pad. The movable pressure plate presses and limits the other side of the fabric. During the resetting process of the transmission frame, in conjunction with external pneumatic equipment, a negative pressure can be formed inside the dust collection box, which transports the dust on the surface of the fabric along the filter tube into the dust collection box, reducing the impact on subsequent printing.

[0008] Preferably, the connecting frame has a movable groove inside, and a snap-fit ​​plate is connected inside the movable groove. The sliding shaft is movably snapped between the snap-fit ​​plates. A hollow tube is provided on the outer wall of the sliding shaft. A tension tube is provided at the top of the sliding shaft. Several elastic inserts communicating with the hollow tube are provided at the bottom of the tension tube. A push ring is sleeved at the bottom of the sliding shaft. Several piston rods inserted inside the hollow tube are provided at the top of the push ring. The push ring can move under the action of the piston rods to change the tension force on the elastic pad.

[0009] Preferably, the auxiliary pressure block is located at the bottom of the sliding shaft. The auxiliary pressure block has a transmission groove on its outside and an elastic pad is movably installed inside the transmission groove. The two ends of the elastic pad are connected to the outer wall of the push ring, which can stretch and lock the elastic pad inside the transmission groove. The design of the auxiliary pressure block combined with the elastic pad provides flexible contact when limiting the fabric. Compared with a hard pressure block, it greatly reduces the risk of leaving indentations or damage on the fabric surface.

[0010] Preferably, a set of reset frames is movably mounted on the tilting frame. The reset frames are rectangular and movably inserted at the top of the tilting frame. The bottom end of the reset frames is mounted at the bottom of the stretching tube. The reset frames are used to pull the stretching tube to deform and change its internal air pressure.

[0011] The top of the reset frame is provided with several locking shafts, and the locking shafts can hold transmission plates. During the movement of the transmission frame, the flat frame at the lower end can abut against the transmission plates, and the flat frame can be intermittently moved to push the feed shaft and the rotary shaft to transmit the movement. During the reset process, the reset frame is driven to pull down the stretching tube, which causes the air pressure to change and push the piston rod and the push ring to move, driving the elastic pad to stretch back and forth, automatically shaking off the dirt and debris adhering to its surface, simplifying maintenance.

[0012] Preferably, each docking plate is movably fitted with a movable end block, and the rear end of the transmission frame is provided with a set of pneumatic telescopic shafts, which are respectively connected to the interior of the movable end blocks at both ends. Each movable end block is provided with an air injection hole for driving the pneumatic telescopic shaft. By driving the movable end block through the pneumatic telescopic shaft, the height of the flat frame at the bottom of the transmission frame can be finely adjusted.

[0013] Preferably, the dust collection box is equipped with a suction pipe and a dust collection pipe, both of which have air injection pipes for connecting to external equipment. The top of the dust collection box has several circular grooves for securing a sealing cover plate. A dust collection pipe is rotatably mounted at the bottom of the sealing cover plate. A rubber plate is installed at the bottom of the inner wall of the dust collection pipe. A circular hole is provided on the sealing cover plate to pass through the dust collection pipe and the dust collection suction pipe. The suction pipe is connected to the dust collection box, and a sponge shaft is inserted inside the suction pipe.

[0014] A rotating shaft is inserted inside the sealing shaft. The rotating shaft passes through the sealing shaft and the transmission frame and is connected to the rubber plate at the bottom of the dust collection pipe. Several feed shafts are connected inside the flattening frame. The feed shafts are rotatably set at the bottom of the rotating shaft. The rotating shaft can rotate when it reciprocates inside the sealing shaft. During subsequent maintenance, the dust collection pipe is driven by the rotating shaft to make reciprocating circular motion. Combined with the swinging and compacting action of the adsorption shaft, the dust is more efficiently collected on its outer wall, which is convenient for subsequent direct rinsing of the dust collection pipe for centralized cleaning. Maintenance is convenient and efficient.

[0015] Preferably, the outer wall of the dust collection pipe is provided with an annular groove, and the annular groove is provided with a number of adsorption shafts. The adsorption shafts are arc-shaped and uniformly arrayed inside the annular groove. The outer wall of the dust collection pipe is provided with a number of air inlet grooves. A sponge shaft can be inserted into the dust collection pipe to effectively prevent fabric debris from entering the pipe and causing blockage, thus ensuring the long-term stable operation of the dust collection function.

[0016] Preferably, a filter tube is inserted inside the suction pipe, and a metal mesh plate is provided at the bottom of the filter tube to assist in filtration.

[0017] Preferably, the top of the buffer pad is equipped with a movable pressure plate, the height of which is adjustable. This movable pressure plate is used to limit the fabric, and together with the adjustable-height movable pressure plate on the other side of the fabric to press and limit it, as well as the auxiliary pressure block to flexibly press against the starting side, together ensure that the fabric reaches a highly flat and stable state on the buffer pad.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention integrates a negative pressure dust collection system through a device consisting of a suction pipe, a dust collection box, and a suction tube. It simultaneously removes surface dust and debris while the fabric is being laid flat, significantly reducing the impact of impurities on subsequent screen printing. Multiple anti-clogging measures are implemented using a filter tube with a metal mesh plate, a sponge shaft inside the dust collection box, and a sponge shaft inside the dust collection tube. These measures effectively prevent fabric debris from entering the pipe and causing blockages, ensuring long-term stable operation of the dust collection function.

[0020] 2. The present invention provides flexible contact when limiting the fabric by combining the auxiliary pressure block with the elastic pad. Compared with the hard pressure block, it greatly reduces the risk of leaving indentations or damage on the fabric surface, effectively avoids the subsequent additional ironing process caused by indentations, saves labor costs and better protects fabrics of different materials.

[0021] 3. This invention uses a pneumatic telescopic shaft to drive the movable end block, which can finely adjust the height of the flattening frame at the bottom of the transmission frame. This design allows the device to easily meet the flattening and transmission needs of fabrics of different thicknesses and materials, reduce wear during processing, and improve the versatility of the equipment.

[0022] 4. During maintenance, the present invention drives the reset frame to pull down the stretching tube, causing a change in air pressure to push the piston rod and push ring to move, which drives the elastic pad to reciprocate and stretch, automatically shaking off the dirt and debris adhering to its surface, thus simplifying maintenance.

[0023] 5. In this invention, the dust collection pipe is driven by the rotating shaft to make reciprocating circular motion during subsequent maintenance. Combined with the swinging and compacting action of the adsorption shaft, the dust is more efficiently collected on its outer wall, which makes it easier to directly rinse the dust collection pipe for centralized cleaning. The maintenance is convenient and efficient.

[0024] 6. This invention, through the structure of an elastic flattening frame combined with a sealing shaft, a feed shaft, and a rotating shaft, can dynamically stretch and flatten the fabric during the movement of the transmission frame. Combined with the adjustable height movable pressure plate on the other side of the fabric for pressing and limiting, and the auxiliary pressure block for flexible pressing on the starting side, it ensures that the fabric reaches a highly flat and stable state on the buffer pad, laying a solid foundation for subsequent high-precision screen printing.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-10 This invention provides a technical solution: a multi-directional adjustable screen printing clamping device, comprising,

[0038] The operating table 1 has a fixed base plate 11 at the top of the operating table 1 that connects to the transmission slide rail 12. The transmission slide rail 12 is equipped with a buffer pad 2 at the top. A lifting frame 3 is provided on one side of the top of the buffer pad 2. A set of connecting seats 31 is provided on one side of the buffer pad 2. A rotating shaft with a guide rail plate is rotatably provided between the connecting seats 31. The lifting frame 3 is movably locked on the guide rail plate. Push rod motors 41 are provided on both sides of the lifting frame 3. A docking plate 42 is provided on the output end of the push rod motor 41. A transmission frame 4 is provided on the outside of the pair of docking plates 42. A dust collection box 44 is provided at the top of the transmission frame 4.

[0039] The lifting frame 3 has several inclined frames 33 on its outer side, and a transmission plate 35 is movably arranged between the inclined frames 33. A sliding shaft 351 connecting 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, and a fabric flattening frame 46 is connected to the sealing shaft 43. The flattening frame 46 is elastic. Several suction pipes 45 communicating with the dust collection box 44 are provided on both sides of the sealing shaft 43 for suctioning the fabric during the flattening process. When it is necessary to flatten and limit the fabric, the fabric can be laid on the top of the buffer pad 2 and follow the lifting frame 3 with the sliding shaft 351. During the process, the auxiliary pressure block 37 presses against one side of the fabric, and the push rod motor 41 on one side operates in conjunction with external equipment, which drives the overall movement of the transmission frame 4. The height of the movable end block 421 is adjusted according to the different fabric materials. During the transmission process, the fabric can be flattened and spread on the buffer pad 2. The movable pressure plate 21 presses and limits the other side of the fabric. During the reset process of the transmission frame 4, in conjunction with the external air pressure equipment, a negative pressure can be formed inside the dust collection box 44, which transports the dust on the surface of the fabric along the filter tube 451 into the dust collection box 44, reducing the impact on subsequent printing.

[0040] like Figure 6 and Figure 7 As shown, the connecting frame 32 has an internal movable groove, and a snap-fit ​​plate 34 is connected inside the movable groove. The sliding shaft 351 is movably snapped between the snap-fit ​​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 tension tube 38. The bottom of the tension tube 38 is provided with several elastic insertion tubes 381 that communicate with the hollow tube. The bottom of the sliding shaft 351 is fitted with a push ring 36. The top of the push ring 36 is provided with several piston rods 361 inserted inside the hollow tube. During the cleaning and maintenance process, the interaction between the transmission plate and the leveling frame 46 can drive the reset frame 331 to move downward and stretch. The deformation of the tension tube 38 can cause a change in air pressure inside, which can move the piston rods 361 at the bottom, thus playing a driving role.

[0041] like Figure 5As shown, the auxiliary pressure block 37 is located at the bottom of the sliding shaft 351. The auxiliary pressure block 37 has a transmission groove on its outside, and an elastic pad 371 is movably installed inside the transmission groove. The two ends of the elastic pad 371 are connected to the outer wall of the push ring 36. The elastic pad 371, which is stuck inside the transmission groove, can be stretched. During the process of limiting the fabric, the elastic pad 371 can be pressed against the surface of the fabric. Compared with the direct contact of the hard auxiliary pressure block 37, the pressing of the fabric surface can be reduced, and the subsequent ironing process to remove the indentation can be reduced.

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

[0043] The top of the reset frame 331 is provided with several locking shafts, and the locking shafts can hold transmission plates. During the movement of the transmission frame 4, the flat frame 46 at the lower end can abut against the transmission plates, and can intermittently move the flat frame 46 to push the feed shaft 461 and the rotary shaft 462 to transmit the movement. As the air pressure changes continuously due to the deformation of the top tension tube 38, the piston rod 361 at the bottom moves. At this time, the push ring 36 resets upward, which can stretch the elastic pad 371 at the bottom. During the reciprocating process, dirt and debris adhering to the bottom fall off, making it convenient for operators to clean and maintain at the same time.

[0044] like Figure 8 As shown, each docking plate 42 is movably fitted with a movable end block 421. The rear end of the transmission frame 4 is provided with a set of pneumatic telescopic shafts, which are respectively connected to the interior of the movable end blocks 421 at both ends. The movable end blocks 421 are provided with air injection holes for driving the pneumatic telescopic shafts. During the process of flattening different fabrics, the position of the movable end blocks 421 can be adjusted according to the actual situation, and the height of the flattening frame 46 can be adjusted, so as to cope with fabrics of different materials and thicknesses and reduce wear during subsequent processing.

[0045] like Figure 10As shown, a suction pipe 441 and a dust collection pipe 442 are respectively installed on the dust collection box 44. Both the suction pipe 441 and the dust collection pipe 442 are provided with air injection pipes for connecting to external equipment. The top of the dust collection box 44 is provided with several circular grooves for locking the sealing cover plate 48. The bottom of the sealing cover plate 48 is rotatably provided with a dust collection pipe 47. The bottom of the inner wall of the dust collection pipe 47 is provided with a rubber plate. The sealing cover plate 48 is provided with a circular hole that passes through the dust collection pipe 47 and the dust collection pipe 442. The suction tube 441 is connected to the dust collection box 44. A sponge shaft is inserted inside the suction tube 441. When it is necessary to vacuum the surface of the fabric, the external air pressure device creates a negative pressure at the suction tube 441, which allows the dust to enter the dust collection box 44 along the suction tube 45. This allows the dust and debris to be stored inside the dust collection box 44, reducing the chance of clogging. In addition, the sponge shaft helps to reduce the chance of dust entering the suction tube 441 and causing clogging.

[0046] A rotating shaft 462 is inserted inside the sealing shaft 43. The rotating shaft 462 passes through the sealing shaft 43 and the rubber plate at the bottom of the dust collection pipe 47, connecting the transmission frame 4. Several feed shafts 461 are connected inside the leveling frame 46. The feed shafts 461 are rotatably mounted 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 collection box 44, the push rod motor 41 and the pneumatic telescopic shaft reset during the reset process of the transmission frame 4, which can position the bottom end of the leveling frame 46 on the tilting frame 33. At this time, the movable end block 421 can also move upward synchronously on the docking plate 42. During the transmission process, the bottom leveling frame 46 can be squeezed against the transmission plate. The elastic flat frame 46 can be contracted and deformed, which can drive the feed shaft 461 and the rotating shaft 462 to move. This causes the dust collection pipe 47 at the top to reciprocate in a circular motion under the action of the rotating shaft 462. At this time, the external air pressure device can be connected to the dust collection suction pipe 442, which can collect dust on the outer wall of the dust collection pipe 47. During the reciprocating circular motion of the dust collection pipe 47, the external suction shaft 471 can swing outward, and the floating dust can be collected. After the suction shaft 471 returns to its original position, it can compact the dust on the outside of the dust collection pipe 47. In subsequent cleaning, most of the dust will be collected on the outside of the dust collection pipe 47, which can be directly rinsed for maintenance.

[0047] like Figure 10 As shown, an annular groove is provided on the outer wall of the dust collection pipe 47, and several sets of adsorption shafts 471 are provided inside the annular groove. The adsorption shafts 471 are arc-shaped and evenly arrayed inside the annular groove. Several air inlet grooves are provided on the outer wall of the dust collection pipe 47. A sponge shaft can be inserted into the dust collection pipe 47. Under the action of the sponge shaft, the entry of dust into the dust collection suction pipe 442 can be reduced, and the sponge shaft can be replaced and maintained regularly to reduce clogging.

[0048] like Figure 9 As shown, a filter tube 451 is inserted inside the suction tube 45. A metal mesh plate is provided at the bottom of the filter tube 451. Airflow can enter the dust collection box 44 through the filter tube 451. The metal mesh plate can act as a barrier to reduce large pieces of fabric debris from clogging the inside of the filter tube 451.

[0049] like Figure 2 and Figure 3 As shown, the top of the buffer pad 2 is equipped with a movable pressure plate 21. The height of the movable pressure plate 21 can be adjusted to limit the fabric and press it to facilitate subsequent printing.

[0050] Working Principle: Firstly, when the fabric needs to be flattened and positioned, it is laid on top of the buffer pad 2. The sliding shaft 351 moves with the lifting frame 3. An auxiliary pressure block 37 presses against one side of the fabric, and the push rod motor 41 on one side, in conjunction with external equipment, drives the entire transmission frame 4. The height of the movable end block 421 is adjusted according to the fabric material. During transmission, the fabric is flattened and laid on the buffer pad 2, and the movable pressure plate 21 presses and positions the other side of the fabric. During the resetting process of the transmission frame 4, external air pressure equipment creates negative pressure inside the dust collection box 44, transporting dust from the fabric surface along the filter tube 451 into the dust collection box 44, reducing its impact on subsequent printing. During vacuuming, the airflow from the external air pressure equipment flows along the suction tube 441, collecting dust inside the dust collection box 44. Combined with the sponge shaft, this reduces the risk of clogging in the suction tube 441.

[0051] Then, after printing on the fabric, the movable pressure plate 21 and the lifting frame 3 can be raised a certain distance to remove the fabric. During the reset process of the transmission frame 4, the push rod motor 41 and the pneumatic telescopic shaft are reset, which can place the bottom of the flattening frame 46 on the tilting frame 33. At this time, the movable end block 421 can also move upward synchronously on the docking plate 42. During the transmission process, the flattening frame 46 at the bottom can squeeze against the transmission plate, which can cause the elastic flattening frame 46 to shrink and deform, which can drive the feed shaft 461 and the rotating shaft 462 to move. This causes the dust collection pipe 47 at the top to reciprocate in a circular motion under the action of the rotating shaft 462. As the external air pressure equipment and the dust collection suction pipe 442 are connected, the dust can accumulate on the outer wall of the dust collection pipe 47 along the airflow. During the reciprocating motion, the adsorption shaft 471 can swing outward to gather and squeeze the dust and other materials, which are then accumulated on the outer wall of the dust collection pipe 47 for easy cleaning and maintenance later.

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

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