Description

Technical Field

[0001] The invention relates to the technical field of printing equipment, in particular to an anti-deflection structure of a clothing screen printing device. Background Art

[0002] Screen printing is a screen printing plate made with silk screen as substrate. Screen printing mainly consists of screen printing plate, scraper, ink, printing table and substrate. Ink is poured on the screen printing plate, and then pressure is applied to the ink through the scraper. It moves from one end of the screen printing plate to the other end. The ink can be squeezed onto the clothing through the mesh of the screen printing plate and the graphic part is printed on the clothing.

[0003] In order to save costs, some smaller garment factories will use manual hand-held screen printing plates to directly print on garments when printing on garments, and will not set a limit device for the screen printing plates. Manual hand-held screen printing plates will be affected by many external factors, which will lead to instability when the manual hand-held screen printing plates are aligned with the garments. This will cause the manual alignment of the screen printing plates with the garments to be skewed, especially for novices. It is difficult for novices to accurately align the screen printing plates with the garments to be printed. At the same time, due to the lack of experience of novices, the screen printing plates will be skewed when printing on the garments, resulting in a certain degree of skewness in the graphic part of the garments, thereby reducing the printing effect of the garments.

[0004] In view of the above problems, the prior art provides a solution. For example, patent application No. 201410833707.0 provides a new type of screen printing machine. The solution can position the object to be printed on the tape machine through a positioning device, and the push-pull cylinder on the manipulator device realizes the downward pressure and upward movement of the scraper, and the printing work is completed by the traction of the driving device; by setting a symmetrical manipulator, the printing efficiency can be effectively improved, the structure is simple, the working efficiency is high, and the problem that the printing pattern of the screen printing machine in the prior art is easy to deviate can be effectively solved. Fig. 9 In order to improve the printing speed of clothing in the prior art, operators evenly install multiple positioning blocks on the track, install two limiting rods at one end of the screen printing plate, and then set a positioning rod used in conjunction with the positioning blocks in the middle part of the screen printing plate. The positioning rod and the two limiting rods form a three-point support effect when in use. Although it can improve the stability of the screen printing plate, the three-point support and the track are all movably installed. Moreover, since the screen printing plate is manually operated, once the force applied to the screen printing plate by the worker is uneven, it is easy to cause one end of the screen printing plate to tilt, which will cause the screen printing plate to deflect, which will cause the text and image printing of the clothing to deflect, thereby reducing the effect of clothing printing.

[0005] To this end, an anti-deflection structure of a clothing screen printing device is proposed to solve the problem in the prior art that the three-point support and positioning block of the screen printing plate are all movably installed, and once the screen printing plate is subjected to external force, one end will be lifted up, thereby causing the screen printing plate to be easily deflected. Summary of the invention

[0006] The purpose of the present invention is to provide an anti-deflection structure for a clothing screen printing device to solve the problem that the screen printing plate is easily lifted at one end due to uneven force, which may cause deflection between the screen printing plate and the clothing, thereby reducing the printing effect of the clothing.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A deflection prevention structure of a clothing screen printing device comprises a track, a positioning block and a screen printing plate, and also comprises a clamping mechanism, a clip, a rubber pad, an deflection prevention mechanism and a clamping block, wherein the clamping mechanism is installed inside the track, the clip is connected to the clamping mechanism, the rubber pad is installed at one end of the clip and is in contact with the screen printing plate, the deflection prevention mechanism is installed inside the screen printing plate, the clamping block is connected to the deflection prevention mechanism, the clamping mechanism controls the clip and the rubber pad to clamp the screen printing plate in the center, and when the screen printing plate rotates toward the clothing, the clamping block is driven by the anti-deflection mechanism to move toward the positioning block and clamp it.

[0009] In the above scheme, the clamping mechanism is used to control the clamping piece to clamp the screen printing plate, and then the rubber pad can improve the stability of the clamping piece clamping the screen printing plate. After the clamping piece clamps the screen printing plate, the screen printing plate can be pressed downward in the direction of clothing. When the screen printing plate is pressed downward, the anti-deflection mechanism will be controlled to drive the two clamping blocks to move in the direction of the positioning block. The two clamping blocks clamp the positioning block to realize the positioning of the screen printing plate, which can prevent the screen printing plate from being deflected when printing on clothing.

[0010] Alternatively, if you want to print on clothing, you can use the method of manually holding the screen printing plate directly, but this method will produce more uncertainties due to human factors. It is impossible to hold the screen printing plate in the same place every time. It is easy for the force applied to the screen printing plate by humans to be uneven when holding the screen printing plate. In addition, when printing on clothing, workers are also easily affected by the outer wall and cause the screen printing plate to shake, which will cause the screen printing plate to deflect, thereby reducing the printing effect of clothing. Of course, you can also use the method of clamping the screen printing plate to print on clothing, avoiding manual holding and improving the accuracy of clothing printing.

[0011] Preferably, the clamping mechanism includes a moving plate, a rotating rod, a moving block, a rotating seat and a rotating disk, the moving plate is installed inside the track, the rotating rod is installed inside the moving plate, the moving block is installed on the outer wall of the rotating rod, the rotating seat is installed inside the moving block and is connected to the clip, the rotating disk is installed at one end of the rotating rod.

[0012] In the above scheme, the rotation of the rotating rod is controlled by the rotating disk, and then the two moving blocks are controlled to move toward each other. The moving block can synchronously drive the rotating seat to move when it moves. Since the clamping block and the moving block are connected by the rotating seat, the moving block can drive the clamping block to move when it moves. When the clamping blocks move toward each other, the screen printing plate can be clamped, the screen printing plate can be positioned, and the screen printing plate can be prevented from being deflected during use.

[0013] Preferably, two moving grooves are symmetrically opened inside the moving plate, and the outer wall of the rotating rod is provided with two screw threads with the same length as the moving grooves, the thread directions of the two screw threads are opposite, and the two screw threads are arranged in cooperation with the moving block.

[0014] In the above scheme, when the rotating disk drives the rotating rod to rotate, it can drive the screw thread to rotate. Under the cooperation of the screw thread and the moving block, the two moving blocks can be driven to move toward each other, and the movable range of the moving block is limited, so that screen printing plates of different specifications can be clamped.

[0015] Preferably, the movable plate includes a limiting portion and a mounting portion, the limiting portion is mounted inside the track, the mounting portion is mounted on the top of the limiting portion, and the limiting portion is configured in a dovetail shape.

[0016] In the above scheme, the movable plate can be easily moved, and the movement of the movable plate is limited at the same time, which can prevent the movable plate from being separated from the track during movement, and can avoid threats to clothing when printing.

[0017] Optionally, if you want to position the screen printing plate, you can directly abut the screen printing plate against the positioning block. This method will cause the screen printing plate to shake between the positioning block when the user holds the screen printing plate to print on clothing due to uneven force applied to the screen printing plate or improper operation of the user. This may cause the screen printing plate to deflect, resulting in poor printing effect on the clothing. In comparison, two clamping blocks can be used to clamp the positioning block, which will increase the contact area between the positioning block and the clamping block. Clamping the positioning block in the middle with two sides facing each other will prevent deflection between the clamping block and the positioning block.

[0018] Preferably, the anti-bias mechanism includes a pushing unit, a rack, a limit plate, a guide rod, a spring, a gear and a screw, the pushing unit is connected to the moving block, the rack is connected to the pushing unit, the limit plate, guide rod and spring are all installed inside the screen printing plate and connected to the rack, the limit plate is configured to be dovetail-shaped, the gear is installed inside the screen printing plate and meshes with the rack, and the screw is installed on one side of the gear.

[0019] In the above scheme, the pushing unit pushes the rack when the clamp rotates, and the rack will mesh with the gear, thereby driving the gear to rotate and driving the screw to rotate. When the two screws rotate, they can drive the two clamps to move towards each other and clamp the positioning block, thereby preventing the clamps and the positioning block from loosening, thereby improving the stability of the connection between the screen printing plate and the positioning block, thereby preventing the screen printing plate from deflecting when printing on clothing.

[0020] Optionally, if you want to control the rotation of the gear, you can directly use a motor drive, but this method has some limitations. First, since the screen printing plate has to be moved all the time to print clothes in different positions, if a motor is installed, it is necessary to set a longer cable for the motor. As the screen printing plate moves, the cable needs to be pulled at the same time, which will affect the printing of the clothes and increase the cost. If a battery is used to power the motor, if the battery is out of power, it is necessary to replace the battery, or notify the printing job to charge the battery, which will lead to a decrease in the printing efficiency of the clothes. Therefore, this method is not adopted. Instead, the power generated by pressing the screen printing plate down and contacting the clothes is used to control the rack to drive the gear to rotate, which can avoid the use of electricity and the occurrence of the above-mentioned risks.

[0021] Preferably, the pushing unit includes a rotating shaft, a disc, a limiting column and a connecting rod, the rotating shaft is installed at one end of the rotating seat, the disc is installed at one end of the rotating shaft, the limiting column is installed at one end of the disc, the connecting rod is installed at one end of the limiting column and is connected to the rack, the limiting column is eccentrically arranged between the disc, the position of the limiting column is point a when the clip is in a vertical state, and the position of the limiting column is point b when the clip is in a horizontal state, and when the limiting column is at point a, the spacing value between one end of the rack and the clamping block is consistent with the length value of the guide rod.

[0022] In the above scheme, when the screen printing plate is pressed, the rotating seat can be driven to rotate through the clamping piece, and the disc can be driven to rotate through the rotating shaft. When the disc rotates, it can drive the limiting column to rotate eccentrically, so as to push the connecting rod, thereby pushing the rack. Through the above arrangement, the clamping block and the positioning block can be clamped when printing clothing, so as to position the screen printing plate, prevent the screen printing plate from being deflected when printing clothing, and avoid reducing the printing effect due to the deflection of the screen printing plate when printing clothing.

[0023] Preferably, the rotation arc of the disc is 60-90 degrees, the path length of the disc rotation is smaller than the translation length of the rack, and the length value of the guide rod is consistent with the translation length value of the limit plate.

[0024] In the above scheme, through the above arrangement, it is possible to ensure that the rotation of the disc and the movement of the rack are kept synchronous, which can prevent obstacles between the disc and the rack during movement and avoid malfunctions of the screen printing plate when printing on clothing.

[0025] Preferably, the limit plate, guide rod, spring, gear and screw are all symmetrically arranged with respect to the center line of the screen printing plate, and the thread directions of the two screws are opposite.

[0026] In the above scheme, the screw clamp blocks can move toward each other, so that the two clamp blocks can clamp the positioning block, which can improve the stability of the screen printing plate when printing on clothing and prevent the screen printing plate from deflecting when printing on clothing.

[0027] Preferably, the center lines of the rotating seat and the clamp coincide with the center lines of the left and right ends of the screen printing plate, and when the limit column is located at point b, the rotating seat and the clamp are both in a horizontal state, and the bottom end of the rotating seat fits with the top end of the mounting portion.

[0028] In the above scheme, by supporting the clip, it is possible to print on the clothing when the screen printing plate and the clothing are in a parallel state, which can avoid poor printing effect caused by the inability of the screen printing plate and the clothing to fit tightly, avoid reducing the contact area between the screen printing plate and the clothing, and prevent the screen printing plate from being skewed when printing on the clothing.

[0029] Preferably, the longitudinal section of the clamp block is an I-shape, and one end of the clamp block is provided with a slot matching the positioning block.

[0030] In the above scheme, it is to facilitate the sliding of the clamping block in the screen printing plate and to facilitate the clamping block to clamp the positioning block, so as to increase the contact area between the clamping block and the positioning block, thereby improving the stability of the connection between the clamping block and the positioning block, and at the same time improving the stability between the screen printing plate and the positioning block, so as to prevent the screen printing plate from being skewed when printing on clothing.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. By controlling the two moving blocks to drive the clamps to move toward each other, and clamping the screen printing plate under the action of the rubber pad, the screen printing plate can be centered relative to the moving plate, and the screen printing plate can be controlled by clamping to print on clothing, thereby avoiding manual hand-held printing of the screen printing plate, avoiding uneven force on the screen printing plate caused by manual operation or improper operation of the staff causing the screen printing plate to tilt when printing on clothing, avoiding errors in clothing printing, and improving the effect of clothing printing.

[0033] 2. By controlling the two clamping blocks to clamp the positioning block, the positioning block can be centered, the contact area between the clamping block and the positioning block can be increased, and thus the stability between the clamping block and the positioning block can be improved, so that the positioning block and the clamping block can obtain additional supporting force, and it can be ensured that the positioning block and the clamping block are not easily deflected by external force. Since the stability between the positioning block and the clamping block is improved, the stability between the screen printing plate and the positioning block can also be improved, thereby preventing the screen printing plate from deflecting when printing on clothing.

[0034] 3. The disc drives the limit column to rotate eccentrically, so that the connecting rod can be controlled to push the rack to move in a straight line. When the screen printing plate is pressed down to print the clothing, the two clamping blocks can be controlled to move in the direction of the positioning block at the same time, the position of the screen printing plate can be fine-tuned, the screen printing plate can be positioned, and the two sets of racks move synchronously, which can avoid the differential speed when the rack drives the gear to rotate, and can ensure the synchronous movement of the two racks, so that one of the racks can avoid contact with the inner wall of the installation groove, thereby avoiding different thrusts on the two ends of the screen printing plate, and will not cause the object to deflect or tilt, so as to achieve the balance of the screen printing plate and avoid the screen printing plate from deflecting when printing on clothing.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. However, the embodiments described below are only some embodiments of the present invention, not all of them. If other embodiments of ordinary technicians in this field are obtained without making creative work, they all belong to the protection scope of the present invention.

[0046] See also Figures 1 to 8 The present invention provides an anti-deflection structure of a clothing screen printing device, and the technical solution is as follows:

[0047] Reference Figure 1 and Figure 2, an anti-deflection structure of a clothing screen printing device, comprising a track 1, a positioning block 2 and a screen printing plate 3, and also comprising a clamping mechanism 4, a clamping piece 5, a rubber pad 6, an anti-deflection mechanism 7 and a clamping block 8. The clamping mechanism 4 is installed inside the track 1. Through the setting of the track 1, the clamping mechanism 4 can be conveniently moved. The path value of the rotation of the front end of the screen printing plate 3 is greater than the spacing value between the clamping block 8 and the positioning block 2. This setting can position and print the clothing after the screen printing plate 3 is completely positioned. The clamping piece 5 is connected to the clamping mechanism 4, and the rubber pad 6 is installed at one end of the clamping piece 5 and fits with the screen printing plate 3. The clamping piece 5 and the rubber pad 6 cooperate with each other and the screen printing plate 3 is clamped under the action of the clamping mechanism 4. By setting the rubber pad 6, the friction between the clamping piece 5 and the screen printing plate 3 can be increased, displacement between the clamping piece 5 and the screen printing plate 3 can be avoided, loosening of the screen printing plate 3 can be avoided, and the stability of the screen printing plate 3 when printing on clothing can be improved. Rectangular grooves are provided at both ends of the screen printing plate 3, and the outer wall of the rubber pad 6 is fitted with the inner wall of the rectangular groove. This setting can position the screen printing plate 3 and limit the installation position of the screen printing plate 3, which can prevent the screen printing plate 3 from being in a different position each time it is installed. The anti-deflection mechanism 7 is installed inside the screen printing plate 3. Through the setting of the anti-deflection mechanism 7, it can be ensured that the screen printing plate 3 always keeps a neat state for printing on clothing, and the clamping block 8 and the anti-deflection mechanism The two clamping blocks 8 are connected with each other by the anti-deviation mechanism 7, and the longitudinal section of the clamping block 8 is I-shaped. Through the operation of the anti-deviation mechanism 7, the two clamping blocks 8 can be driven to move toward each other. When the spacing between the two clamping blocks 8 reaches a certain value, the positioning block 2 can be clamped. The positioning block 2 is set as a rectangular block. By cooperating with the two clamping blocks 8, the clamping block 8 can be conveniently clamped to the positioning block 2, thereby improving the stability of the screen printing plate 3 and preventing the screen printing plate 3 from deflecting when printing clothing. A card slot 9 matching the positioning block 2 is provided at one end of the clamping block 8. The vertical section of the card slot 9 is trapezoidal, narrow at the top and wide at the bottom, which can prevent the top of the card slot 9 from causing an obstacle between the positioning block 2 and the top of the card slot 9 when the clamping block 8 moves toward the positioning block 2 when rotating. The arrangement can facilitate the clamping mechanism 4 to control the clamping piece 5 and the rubber pad 6 to clamp the screen printing plate 3 in the center. When the screen printing plate 3 rotates toward the clothing, the anti-deflection mechanism 7 drives the clamping block 8 to move toward the positioning block 2 and clamp it. When the clamping block 8 moves toward each other, even if the spacing between the two clamping blocks 8 and the positioning block 2 is inconsistent, when one of the clamping blocks 8 contacts the positioning block 2, the other clamping block 8 will be controlled to move toward the positioning block 2 under the action of the two clamping blocks 8 moving toward each other. At the same time, the moving plate 41 can be controlled to slide on the track 1, thereby driving the screen printing plate 3 to move, and achieving the coincidence of the center line of the screen printing plate 3 and the clothing. When the other clamping block 8 also contacts the positioning block 2, the two clamping blocks 8 can clamp the positioning block 2.

[0048] As an embodiment of the present invention, refer to Figures 3 to 8The clamping mechanism 4 includes a moving plate 41, a rotating rod 42, a moving block 43, a rotating seat 44 and a rotating disk 45. The moving plate 41 is installed inside the track 1. A traveling dovetail groove is provided inside the track 1. Through the setting of the dovetail groove, it is convenient for the staff to control the moving plate 41 to move, so that it is convenient to print the clothes on the moving path. By controlling the moving plate 41 to move in the dovetail groove, it is only necessary to manually pull the moving plate 41, which can avoid manually holding the screen printing plate 3 to move, and can reduce the work intensity of the staff. The moving plate 41 includes a limiting portion 411 and a mounting portion 412. The limiting portion 411 is installed inside the track 1. By setting the limiting portion 411, it can be aligned with the dovetail groove. The movable plate 41 cooperates with each other to facilitate the movement of the movable plate 41. The length of the movable plate 41 only needs to be less than the sum of the lengths between the screen printing plate 3 and the two clamping blocks 8. In this way, the screen printing plate 3 can be clamped more quickly. The mounting portion 412 is mounted on the top of the limiting portion 411. The limiting portion 411 is arranged in a dovetail shape. The limiting portion 411 is installed inside the traveling dovetail groove. The limiting portion 411 is arranged in a dovetail shape that matches the dovetail groove. The movable plate 41 can be limited while facilitating the movement of the movable plate 41, and can prevent the movable plate 41 from falling off from the track 1, and can improve the stability of the movable plate 41 when moving. The rotating rod 42 is installed inside the movable plate 41, and the movable block 43 is installed on the rotating rod 42. The outer wall, the rotating seat 44 is installed inside the moving block 43, and the clamping piece 5 can be controlled to rotate by controlling the rotating seat 44 to rotate inside the moving block 43, so that the screen printing plate 3 clamped by the clamping piece 5 can be conveniently fitted or separated from the clothing. The center line of the rotating seat 44 and the clamping piece 5 coincides with the center line of the left and right ends of the screen printing plate 3, and is connected to the clamping piece 5. Through the above arrangement, the centering arrangement of the clamping piece 5 can be achieved, and the height of the screen printing plate 3 at both ends of the clamping piece 5 can be ensured to be consistent, so that the screen printing plate 3 can maintain stability when in use, and the screen printing plate 3 can be prevented from being unbalanced when in use. The rotating disk 45 is installed at one end of the rotating rod 42, and two moving grooves 46 are symmetrically provided inside the moving plate 41, through which the rotating plate 45 is installed. By setting the moving groove 46, the moving block 43 can be easily moved, and the movement space of the moving block 43 can be limited, so that the screen printing plates 3 of different specifications can be clamped. The outer wall of the rotating rod 42 is provided with two screw teeth 47 with the same length as the moving groove 46, and the thread directions of the two screw teeth 47 are opposite. The two screw teeth 47 are arranged in coordination with the moving block 43. When the rotating rod 42 is rotated, it can drive the screw teeth 47 to rotate. Since the thread directions of the two screw teeth 47 are opposite, the two moving blocks 43 can be driven to move toward each other, thereby driving the clamping block 8 connected to the moving block 43 through the rotating seat 44 to move toward each other. When the distance between the two clamping blocks 8 gradually approaches, the screen printing plate 3 can be gradually clamped.

[0049] In the above scheme, by controlling the rotation of the rotating disk 45, the rotating disk 45 can control the rotation of the rotating rod 42 when rotating, and the rotating rod 42 can drive the screw thread 47 to rotate when rotating. The screw thread 47 can control the two moving blocks 43 to move toward each other when rotating, and can drive the two clamps 5 to move at the same time. When the distance between the two clamps 5 is gradually reduced, the screen printing plate 3 can be clamped, and the screen printing plate 3 can be prevented from falling off. By clamping the screen printing plate 3 for printing, it is possible to avoid manually holding the screen printing plate 3, thereby improving the stability of the screen printing plate 3 during printing, preventing the screen printing plate 3 from being skewed during printing, and improving the printing effect of clothing.

[0050] As an embodiment of the present invention, refer to Figures 5 to 8The anti-deflection mechanism 7 includes a pushing unit 71, a rack 72, a limit plate 73, a guide rod 74, a spring 75, a gear 76 and a screw 77. The pushing unit 71 is connected to the moving block 43, and the rack 72 is connected to the pushing unit 71. The rack 72 can be pushed by the pushing unit 71. The limit plate 73, the guide rod 74 and the spring 75 are all installed inside the screen printing plate 3 and connected to the rack 72. The limit plate 73 is set in a dovetail shape. The screen printing plate 3 is provided with a mounting groove. The rack 72, the limit plate 73, the guide rod 74, the spring 75, the gear 76 and the screw 77 6 are all installed in the installation groove, and a running groove is opened at the bottom of the inner wall of the installation groove. The running groove is set to a dovetail shape that matches the limit plate 73. Through the above arrangement, the guiding positioning of the movement of the rack 72 can be achieved, and the rack 72 can be moved on a fixed line. A circular hole is opened inside the limit plate 73, and the diameter of the circular hole is consistent with the diameter value of the guide rod 74. When the rack 72 drives the limit plate 73 to move in the running groove, the guide rod 74 will enter the circular hole and can squeeze the spring 75 at the same time, so as to buffer the movement of the rack 72 and at the same time When the positioning plate 73 is separated from the guide rod 74, the limiting plate 73 is pushed to accelerate the reset speed of the limiting plate 73. The gear 76 is installed inside the screen printing plate 3 and meshes with the rack 72. The rack 72 moves horizontally under the action of the pushing unit 71. The rack 72 can drive the gear 76 to rotate when it moves horizontally. The screw 77 is installed on one side of the gear 76. The rotation of the gear 76 can drive the screw 77 to rotate. The rotation of the screw 77 can drive the clamping block 8 to move toward the positioning block 2. The limiting plate 73, the guide rod 74, the spring 75, the gear 76 and the screw rod 77 are symmetrically arranged with respect to the center line of the screen printing plate 3, and the thread directions of the two screw rods 77 are opposite. Through the above arrangement, the two clamping blocks 8 can move toward each other, and the distance between the two clamping blocks 8 gradually becomes smaller, so that the positioning block 2 can be clamped. The connection between the positioning block 2 and the clamping block 8 is a rectangular arrangement. When the clamping block 8 moves toward the positioning block 2, the positioning block 2 and the clamping block 8 can fit tightly, which can increase the supporting area of ​​the clamping block 8, thereby providing additional support and stability, and avoiding tilting or offset between the positioning block 2 and the clamping block 8.

[0051] In the above scheme, when the screen printing plate 3 rotates toward the clothing direction, the rack 72 will be pushed by the pushing unit 71. When the rack 72 is pushed, it can drive the two screws 77 to rotate through the gear 76. When the two screws 77 rotate, they can drive the two clamping blocks 8 to move toward the positioning block 2 and clamp the positioning block 2. The positioning block 2 can fit between the clamping blocks 8, so that the positioning block 2 can be prevented from being deflected when printing on clothing. By arranging clamping blocks 8 on both sides of the positioning block 2, the support area of ​​the positioning block 2 can be expanded, so that when the center of gravity deviates from the support point, the positioning block 2 can still maintain balance. By providing additional support for the positioning block 2, the stability of the positioning block 2 can be increased, so that it is not easily affected by external forces and deflected or tilted, which can improve the effect of clothing printing and avoid errors in clothing printing.

[0052] As an embodiment of the present invention, refer to Figures 5 to 8The pushing unit 71 includes a rotating shaft 711, a disc 712, a limiting column 713 and a connecting rod 714. The rotating shaft 711 is installed at one end of the rotating seat 44, and the disc 712 is installed at one end of the rotating shaft 711. The rotating shaft 711 can realize that the clamping piece 5 drives the clamped screen printing plate 3 to rotate in the direction of the clothing and drives the disc 712 to rotate. The rotating shaft 711 and the rotating seat 44 are concentrically arranged. The rotating seat 44 drives the clamping piece 5 to rotate a certain degree, and the rotating shaft 711 will also drive the disc 712 to rotate the same degree. The rotation arc of the disc 712 is 60-90 degrees. Through the above arrangement, the screen printing plate 3 can be ensured to be in an inclined state when the clothing is not printed. At this time, it is convenient for the staff to operate the screen printing plate 3, and it is convenient to disassemble the screen printing plate 3. The path length of the rotation of the disk 712 is less than the translation length of the rack 72. The length value of the guide rod 74 is consistent with the translation length value of the limit plate 73. Through the above arrangement, the rack 72 and the limit plate 73 can move a certain distance after the disk 712 rotates a certain distance. There is a certain correlation between the path length of the rotation of the disk 712 and the translation distance of the rack 72. The limit column 713 is installed at one end of the disk 712, and the connecting rod 714 is installed at one end of the limit column 713 and is connected to the rack 72. The eccentric arrangement between the limit column 713 and the disk 712 The connecting rod 714 is connected to the rack 72, and this arrangement is to facilitate the disassembly of the connecting rod 714 and the rack 72, so as to facilitate the staff to replace the screen printing plate 3. When the disc 712 drives the limiting column 713 to rotate, the limiting column 713 can be eccentrically rotated, so that the connecting rod 714 can push the rack 72. When the limiting column 713 is located at point b, the rotating seat 44 and the clamping piece 5 are both in a horizontal state, and the bottom end of the rotating seat 44 is in contact with the top end of the mounting portion 412. Through the above arrangement, the rotating seat 44 can be supported, and the screen printing plate 3 can be printed on clothing in a horizontal state. When the clamping piece 5 is in a vertical state The position of the limiting column 713 is point a, and the position of the limiting column 713 is point b when the clamp 5 is in a horizontal state. When the limiting column 713 is at point a, the spacing value between one end of the rack 72 and the clamping block 8 is consistent with the length value of the guide rod 74. Through the above-mentioned setting, the rack 72 can be fitted with the inner wall of the installation groove. At this time, the clamping block 8 and the positioning block 2 are pressed tightly, and the connecting rod 714 will press the rack 72 tightly, which can improve the stability of the screen printing plate 3, prevent the screen printing plate 3 from being tilted due to improper operation by the user or uneven force applied to the screen printing plate 3 by the user during printing, and improve the effect of the screen printing plate 3 on clothing printing.

[0053] In the above scheme, the user controls the screen printing plate 3 to rotate toward the clothing. When the screen printing plate 3 rotates, it can drive the rotating seat 44 to rotate through the clamp 5. When the rotating seat 44 rotates, it can drive the disk 712 to rotate through the rotating shaft 711. When the disk 712 rotates, it can control the limiting column 713 to rotate eccentrically. When the limiting column 713 rotates from point a to point b, it can gradually push the rack 72 through the connecting rod 714. Due to the setting of the running groove, it can be ensured that the rack 72 can only move in a fixed path, thereby improving the stability of the screen printing plate 3, and realizing that the screen printing plate 3 can only print on clothing at a fixed angle, thereby preventing the screen printing plate 3 from being skewed during printing.

[0054] Working principle: before use, the user places the screen printing plate 3 between the two clamping pieces 5, and then controls the two clamping pieces 5 to move toward each other, and under the action of the rubber pad 6, the two clamping pieces 5 can clamp the screen printing plate 3, and then the user places the two clamping blocks 8 at both ends of the positioning block 2, and then the user presses down the clamped screen printing plate 3, and when the screen printing plate 3 is pressed downward, it can drive the two clamping blocks 8 to move toward the positioning block 2 on the screw 77, and the two clamping blocks 8 move toward each other and gradually approach the positioning block 2. When the clamping blocks 8 move toward the positioning block 2, the position of the movable plate 41 on the track 1 can be fine-tuned until the two clamping blocks 8 completely clamp the positioning block 2, and then the user continues to press down the screen printing plate 3 to print on the clothing;

[0055] Specifically, the user inserts the limiting portion 411 of the movable plate 41 into the dovetail groove, and then controls the movable plate 41 to slide on the track 1. When the movable plate 41 moves to the front of the garment to be printed, the user aligns the rectangular groove of the screen printing plate 3 with the rubber pad 6. Then, the user controls the rotation rod 42 to rotate through the rotating disk 45. When the rotating rod 42 rotates, it can drive the screw 47 installed on the outer wall to rotate. Since the two screws 47 are arranged in opposite directions, the two movable blocks 43 can be controlled to move toward each other in their respective movable grooves 46. When the movable block 43 moves, it can drive the clamping piece 5 to move toward the screen printing plate 3 through the rotating seat 44. When the clamping piece 5 moves, it can drive the rubber pad 6 to enter the rectangular groove, so as to clamp the screen printing plate 3. Then, the connecting rod 714 is clamped with the rack 72, so that the screen printing plate 3 can be avoided from being manually held.

[0056] When the screen printing plate 3 is clamped, the screen printing plate 3 is pressed downward. When the screen printing plate 3 is pressed downward, always pay attention to the positions of the two clamping blocks 8. When the two clamping blocks 8 are located on both sides of the positioning block 2, the screen printing plate 3 can continue to be pressed downward. When the screen printing plate 3 is pressed downward, the clamping piece 5 will drive the rotating seat 44 to rotate in the moving block 43. The rotating seat 44 can drive the rotating shaft 711 to rotate when rotating, and the rotating shaft 711 can drive the disc 712 to rotate when rotating. Due to the eccentric arrangement between the limiting column 713 and the disc 712, the disc 712 can drive the limiting column 713 to rotate eccentrically when rotating. When the limiting column 713 rotates from point a to point b, the limiting column 713 can push the rack 72 through the connecting rod 714, and limit the movement of the rack 72 through the limiting plate 73. At the same time, when the rack 72 is pushed, the guide rod 74 in the mounting groove will enter the circular groove. The hole can guide the movement of the rack 72, prevent the rack 72 from being deflected when moving, and can squeeze the spring 75 to buffer the movement of the rack 72. The rack 72 can drive the gear 76 to rotate during the movement. The gear 76 can drive the screw 77 to rotate when rotating. The screw 77 can drive the two clamping blocks 8 to move toward the positioning block 2 when rotating. The distance between the two clamping blocks 8 and the positioning block 2 gradually decreases. The user needs to adjust the distance between the two clamping blocks 8 and the positioning block 2 at the same time, so that the two clamping blocks 8 can be conveniently clamped to the positioning block 2. After the clamping blocks 8 clamp the positioning block 2, the user can continue to press the screen printing plate 3 downward to print the clothes. By avoiding the manual holding of the screen printing plate 3 to print the clothes, the deflection of the screen printing plate 3 caused by many human factors can be avoided, and the effect of clothing printing can be improved.

[0057] When the printing of the clothing is completed, the user only needs to lift the screen printing plate 3, and the rotating shaft 711, the disc 712, the limiting column 713, the connecting rod 714, the rack 72, the limiting plate 73, the spring 75, the gear 76, the screw 77 and the clamping block 8 will all perform the opposite movement to the above. When the screen printing plate 3 is reset, the user can move the movable plate 41 and move the movable plate 41 to the front of the next clothing to be printed to realize the printing of the next clothing.
