Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing equipment, in particular to a deviation prevention structure of a garment screen printing device. BACKGROUND

[0002] Screen printing is a screen printing plate made of a screen as a substrate, and screen printing mainly consists of a screen printing plate, a squeegee, ink, a printing table and a printing object. The ink is poured on the screen printing plate, and then the ink is pressed by the squeegee. The ink is pressed on the garment through the screen printing plate from one end to the other end, and the text part is printed on the garment.

[0003] Some small garment factories will use manual screen printing plate to directly print on the garment in order to save costs, and no limiting device for the screen printing plate will be set. The manual screen printing plate will be affected by many external factors, which will cause the manual screen printing plate to be unstable when it is aligned with the garment. This will cause the manual screen printing plate to be skewed when it is aligned with the garment, especially for beginners. It is difficult for beginners to accurately align the screen printing plate with the garment to be printed. In addition, the lack of experience of beginners will cause the screen printing plate to be skewed when printing on the garment, which will cause the text part printed on the garment to be skewed, thereby reducing the printing effect of the garment.

[0004] In view of the above problems, the prior art provides a solution, for example, patent application No. 201410833707.0 provides a new screen printing machine. The positioning device can position the printing object on the tape machine. The push-pull cylinder on the mechanical hand device realizes the depression and lifting of the squeegee. The traction of the driving device completes the printing work. The symmetrical mechanical hand can effectively improve the printing efficiency, and the structure is simple and the working efficiency is high. It can effectively solve the problem of easy deviation of the printed pattern of the screen printing machine in the prior art. Referring to Figure 9 In order to improve the printing speed of the garment, the operator installs multiple positioning blocks on the track, installs two limiting rods at one end of the screen printing plate, and sets a positioning rod at the middle part of the screen printing plate for cooperation with the positioning block. 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 movably installed. Since the screen printing plate is manually operated, if the worker applies uneven force to the screen printing plate, the one end of the screen printing plate will be raised, which will cause the screen printing plate to be skewed, thereby causing the text printing on the garment to be skewed, thereby reducing the printing effect of the garment.

[0005] To this end, a deviation prevention structure of a clothing screen printing device is provided to solve the problem that the screen printing plate is prone to deviation due to uneven force and tilting at one end, which leads to deviation between the screen printing plate and the clothing and reduces the printing effect of the clothing. SUMMARY

[0006] The purpose of the present application is to provide a deviation prevention structure of a clothing screen printing device to solve the problem that the screen printing plate is prone to deviation due to uneven force and tilting at one end, which leads to deviation between the screen printing plate and the clothing and reduces the printing effect of the clothing.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0008] A deviation prevention structure of a clothing screen printing device includes a track, a positioning block, and a screen printing plate, and further includes a clamping mechanism, a clamping piece, a rubber pad, a deviation prevention mechanism, and a clamping block. The clamping mechanism is installed inside the track. The clamping piece is connected to the clamping mechanism. The rubber pad is installed at one end of the clamping piece and is in contact with the screen printing plate. The deviation prevention mechanism is installed inside the screen printing plate. The clamping block is connected to the deviation prevention mechanism. The clamping mechanism controls the clamping piece and the rubber pad to clamp the screen printing plate in the center. When the screen printing plate rotates towards the clothing, the deviation prevention mechanism drives the clamping block to move towards the positioning block and clamp it.

[0009] In the above-mentioned scheme, the clamping mechanism controls the clamping piece to clamp the screen printing plate, and 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 downwards towards the clothing. The deviation prevention mechanism drives the two clamping blocks to move towards the positioning block when the screen printing plate is pressed downwards. The two clamping blocks clamp the positioning block to achieve positioning of the screen printing plate and prevent the screen printing plate from deviating during printing on the clothing.

[0010] Alternatively, to print on the clothing, the screen printing plate can be held directly by hand. However, this method may have many uncertainties due to human factors. It is impossible to ensure that the screen printing plate is held at the same position every time. The force applied to the screen printing plate by the worker may not be uniform, and the screen printing plate may shake during printing on the clothing due to external factors. This may cause the screen printing plate to deviate and reduce the printing effect of the clothing. Alternatively, the screen printing plate can be clamped to print on the clothing, which avoids manual holding and improves the accuracy of clothing printing.

[0011] Preferably, the clamping mechanism comprises a moving plate, a rotating rod, a moving block, a rotating seat and a rotating disc, 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 connected with the clamping piece, and the rotating disc is installed on one end of the rotating rod.

[0012] In the above scheme, the rotating disc controls the rotation of the rotating rod, and then controls the movement of the two moving blocks towards each other. The moving block can drive the rotating seat to move synchronously when moving. Since the clamping block and the moving block are connected through the rotating seat, the moving block can drive the clamping block to move when moving. When the clamping block moves towards each other, it can clamp and position the screen printing plate, and prevent the screen printing plate from being skewed during use.

[0013] Preferably, two moving grooves are symmetrically formed in the inside of the moving plate, two screw threads with the same length as the moving grooves are arranged on the outer wall of the rotating rod, the screw 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, the rotating disc drives the rotating rod to rotate, which drives the screw thread to rotate. Under the cooperation of the screw thread and the moving block, the two moving blocks can move towards each other, and the moving range of the moving block is limited, so that screen printing plates of different specifications can be clamped.

[0015] Preferably, the moving plate comprises a limiting portion and a mounting portion, the limiting portion is installed inside the track, the mounting portion is installed at the top end of the limiting portion, and the limiting portion is in the shape of a swallowtail.

[0016] In the above scheme, the moving plate can be conveniently moved, and the movement of the moving plate is limited, which can prevent the moving plate from being separated from the track during movement and avoid threatening the printing of the garment.

[0017] Optionally, to position the screen printing plate, the screen printing plate can be directly abutted with the positioning block. This method will cause the user to apply uneven force to the screen printing plate when holding the screen printing plate to print the garment, or the user to operate improperly, causing the screen printing plate and the positioning block to shake, which may cause the screen printing plate to be skewed, resulting in poor printing effect of the garment. In comparison, the positioning block can be clamped by two clamping blocks, which increases the contact area between the positioning block and the clamping block, and clamps the positioning block in the middle, preventing the clamping block and the positioning block from being skewed.

[0018] Preferably, the deviation prevention mechanism comprises a pushing unit, a rack, a limiting plate, a guide rod, a spring, a gear and a screw rod, the pushing unit is connected with the moving block, the rack is connected with the pushing unit, the limiting plate, the guide rod and the spring are all installed inside the silk screen printing plate and connected with the rack, the limiting plate is in dovetail shape, the gear is installed inside the silk screen printing plate and engaged with the rack, and the screw rod is installed on one side of the gear.

[0019] In the above scheme, the pushing unit pushes the rack when the clamping piece rotates, the rack is engaged with the gear, so as to drive the gear to rotate, and the screw rod also rotates, the two screw rods drive the two clamping blocks to move towards each other when rotating, and clamp the positioning block, so as to prevent the clamping block and the positioning block from loosening, thereby improving the stability of the connection between the silk screen printing plate and the positioning block, and preventing the silk screen printing plate from deviating when printing the clothes.

[0020] Optionally, if you want to control the rotation of the gear, you can directly use a motor to drive, but this way has some limitations. First of all, since the silk screen printing plate always needs to move to print clothes at different positions, if a motor is installed, a relatively long cable needs to be provided for the motor. With the movement of the silk screen printing plate, the cable also needs to be pulled, which will affect the printing of the clothes and increase the cost. If a battery is used to power the motor, the battery needs to be replaced or charged if it runs out of power, which will reduce the efficiency of the clothes printing. Therefore, this way is not adopted, but the silk screen printing plate is pressed down, that is, the power generated when the silk screen printing plate contacts the clothes is used to control the rack to drive the gear to rotate, which can avoid the use of electricity and avoid the above risks.

[0021] Preferably, the pushing unit comprises 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 connected with the rack, the limiting column and the disc are eccentrically arranged, the position of the limiting column when the clamping piece is in the vertical state is point a, the position of the limiting column when the clamping piece is in the horizontal state is point b, and the distance between one end of the rack and the clamping block when the limiting column is at point a is consistent with the length of the guide rod.

[0022] In the above scheme, when pressing the screen printing plate, the rotating seat can be driven to rotate by the clamping piece, and the disc can be driven to rotate by the rotating shaft, and the limiting column can be driven to eccentric rotation when the disc rotates, so that the connecting rod can be pushed, and the rack can be pushed. Through the above setting, the clamping block and the positioning block can be clamped when printing the clothes, so that the screen printing plate can be positioned, and the screen printing plate can be prevented from being skewed when printing the clothes, and the printing effect of the clothes can be avoided. The screen printing plate is skewed during printing.

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

[0024] In the above scheme, through the above setting, the rotation of the disc and the movement of the rack can be kept synchronous, the disc and the rack can be prevented from being obstructed during movement, and the screen printing plate can be prevented from malfunctioning during printing the clothes.

[0025] Preferably, the limiting plate, the guide rod, the spring, the gear and the screw are symmetrically arranged with the center line of the screen printing plate, and the threads of the two screws are opposite.

[0026] In the above scheme, the opposite movement of the screw clamping block can be realized, so that the two clamping blocks can clamp the positioning block, the stability of the screen printing plate during printing the clothes can be improved, and the screen printing plate can be prevented from being skewed during printing the clothes.

[0027] Preferably, the center lines of the rotating seat and the clamping piece coincide with the center lines of the left and right ends of the screen printing plate, the rotating seat and the clamping piece are in a horizontal state when the limiting column is located at point b, and the bottom end of the rotating seat is attached to the top end of the mounting part.

[0028] In the above scheme, by supporting the clamping piece, the clothes can be printed when the screen printing plate and the clothes are in a parallel state, the printing effect caused by the failure of the screen printing plate and the clothes to closely adhere to each other can be avoided, the contact area between the screen printing plate and the clothes can be reduced, and the screen printing plate can be prevented from being skewed during printing the clothes.

[0029] Preferably, the longitudinal section of the clamping block is H-shaped, and the clamping block is provided with a clamping groove matched with the positioning block at one end.

[0030] In the above scheme, it is convenient for the clamping block to slide in the screen printing plate, and the clamping block can clamp the positioning block, the contact area between the clamping block and the positioning block can be increased, the stability of the connection between the clamping block and the positioning block can be improved, the stability between the screen printing plate and the positioning block can be improved, and the screen printing plate can be prevented from being skewed during printing the clothes.

[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 clamping pieces to move toward each other, and clamping the screen printing plate with the cooperation 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 the clothing. This can avoid manual holding of the screen printing plate for printing, and can avoid 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 the clothing, which can avoid errors in clothing printing and can improve 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 can ensure 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 as to control the connecting rod 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 toward the positioning block at the same time, so that the position of the screen printing plate can be fine-tuned and the screen printing plate can be positioned. 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 mounting groove, thereby avoiding different thrusts at both ends of the screen printing plate, which will not cause the object to deflect or tilt, and can achieve the balance of the screen printing plate, and can avoid the screen printing plate from deflecting when printing on clothing.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. However, the embodiments described below are only some of the embodiments of the present application, not all. Other embodiments obtained by those skilled in the art without making creative efforts are also within the protection scope of the present application.

[0046] Please refer to Figures 1 to 8 The present application provides a kind of anti-deviation structure of clothing screen printing device, and the technical solutions are as follows:

[0047] Refer to Figure 1 And Figure 2The application discloses a deviation preventing structure of a clothing screen printing device, which comprises a track 1, a positioning block 2 and a screen printing plate 3, and further comprises a clamping mechanism 4, a clamping piece 5, a rubber pad 6, a deviation preventing mechanism 7 and a clamping block 8. The clamping mechanism 4 is installed in the track 1, and the track 1 can facilitate the movement of the clamping mechanism 4. The rotating path value 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, so that the clothing can be positioned and printed after the screen printing plate 3 is completely positioned. The clamping piece 5 is connected with the clamping mechanism 4, the rubber pad 6 is installed at one end of the clamping piece 5 and is attached to the screen printing plate 3. The clamping piece 5 and the rubber pad 6 are matched with each other and are clamped to the screen printing plate 3 under the action of the clamping mechanism 4. Meanwhile, the friction between the clamping piece 5 and the screen printing plate 3 can be increased by the rubber pad 6, so that the displacement between the clamping piece 5 and the screen printing plate 3 can be avoided, the screen printing plate 3 can be prevented from loosening, and the stability of the screen printing plate 3 during printing can be improved. Rectangular grooves are formed at both ends of the screen printing plate 3, and the rubber pad 6 is attached to the inner wall of the rectangular groove of the outer wall. This structure can position the screen printing plate 3, limit the installation position of the screen printing plate 3, and prevent the installation position of the screen printing plate 3 from being different every time. The deviation preventing mechanism 7 is installed in the screen printing plate 3, so that the screen printing plate 3 can be kept in a neat state during printing. The clamping block 8 is connected with the deviation preventing mechanism 7, the longitudinal section of the clamping block 8 is in the shape of an I-beam, the deviation preventing mechanism 7 can drive the two clamping blocks 8 to move towards each other, the clamping block 8 can clamp the positioning block 2 when the spacing between the two clamping blocks 8 reaches a certain value, the positioning block 2 is in the shape of a rectangular block, the clamping block 8 can clamp the positioning block 2 by matching with the two clamping blocks 8, so that the stability of the screen printing plate 3 can be improved, and the screen printing plate 3 can be prevented from being deviated during printing. A clamping groove 9 matched with the positioning block 2 is formed at one end of the clamping block 8, the vertical section of the clamping groove 9 is in the shape of a trapezoid, the top is narrow and the bottom is wide, so that the clamping groove 9 can be prevented from being blocked by the positioning block 2 when the clamping block 8 rotates and moves towards the positioning block 2. The clamping groove 9 can facilitate the clamping piece 5 and the rubber pad 6 to clamp the screen printing plate 3 in the middle. When the screen printing plate 3 rotates towards the clothing, the clamping block 8 is driven by the deviation preventing mechanism 7 to move towards the positioning block 2 and clamp the positioning block 2. When the spacing between the two clamping blocks 8 and the positioning block 2 is inconsistent, the clamping block 8 can control the other clamping block 8 to move towards the positioning block 2 under the action of the two clamping blocks 8 moving towards each other, and the moving plate 41 can be controlled to slide on the track 1, so that the screen printing plate 3 can be driven to move and be coincided with the center line of the clothing. When the other clamping block 8 also contacts with the positioning block 2, the two clamping blocks 8 can clamp the positioning block 2.

[0048] As an embodiment of the application, refer to Figures 3 to 8The clamping mechanism 4 comprises a moving plate 41, a rotating rod 42, a moving block 43, a rotating seat 44 and a rotating disc 45. The moving plate 41 is installed inside the track 1, and a running dovetail groove is formed in the track 1. The setting of the dovetail groove can facilitate the control of the moving plate 41 to move, so that the clothes on the moving path can be conveniently printed. By controlling the movement of the moving plate 41 in the dovetail groove, the manual pulling of the moving plate 41 can avoid the manual movement of the screen printing plate 3, and the working strength of the workers can be reduced. The length of the moving plate 41 is less than the sum of the length between the screen printing plate 3 and the two clamping blocks 8, so that the screen printing plate 3 can be clamped more quickly. The installation part 412 is installed at the top end of the limiting part 411. The limiting part 411 is set in a dovetail shape and is installed in the running dovetail groove. The limiting part 411 is set in a dovetail shape matched with the dovetail groove, which can conveniently move the moving plate 41 and limit the moving plate 41. The moving plate 41 can be prevented from falling off the track 1, and the stability of the moving plate 41 during movement can be improved. The rotating rod 42 is installed inside the moving plate 41. The moving block 43 is installed on the outer wall of the rotating rod 42. The rotating seat 44 is installed inside the moving block 43. By controlling the rotation of the rotating seat 44 in the moving block 43, the rotation of the clamping piece 5 can be controlled, so that the screen printing plate 3 clamped by the clamping piece 5 can be conveniently attached to or separated from the clothes. The center lines of the rotating seat 44 and the clamping piece 5 coincide with the center lines of the left and right ends of the screen printing plate 3 and are connected with the clamping piece 5. Through the above setting, the clamping piece 5 can be centrally arranged, the height of the screen printing plate 3 at both ends of the clamping piece 5 can be ensured to be consistent, the stability of the screen printing plate 3 during use can be maintained, and the imbalance of the screen printing plate 3 during use can be avoided. The rotating disc 45 is installed at one end of the rotating rod 42. Two moving grooves 46 are symmetrically formed in the moving plate 41. The setting of the moving grooves 46 can facilitate the movement of the moving block 43 and limit the movement space of the moving block 43, so that different specifications of the screen printing plate 3 can be clamped. Two screw threads 47 with the same length as the moving grooves 46 are arranged on the outer wall of the rotating rod 42. The screw threads of the two screw threads 47 are opposite. The two screw threads 47 are arranged in cooperation with the moving block 43. When the rotating rod 42 rotates, the screw threads 47 can be driven to rotate. Since the screw threads of the two screw threads 47 are opposite, the two moving blocks 43 can be driven to move towards each other, so that the clamping blocks 8 connected with the moving block 43 through the rotating seat 44 can be driven to move towards 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 disc 45, the rotating disc 45 can control the rotation of the rotating rod 42 when rotating, the rotating rod 42 can drive the screw teeth 47 to rotate when rotating, the screw teeth 47 can control the two moving blocks 43 to move towards each other, and at the same time can drive the two clamping pieces 5 to move, when the distance between the two clamping pieces 5 gradually decreases, the silk screen printing plate 3 can be clamped, the silk screen printing plate 3 can be prevented from falling off, by clamping the silk screen printing plate 3 for printing, the silk screen printing plate 3 can be avoided to be manually held, so that the stability of the silk screen printing plate 3 during printing can be improved, the silk screen printing plate 3 can be prevented from being skewed during printing, and the printing effect of the garment can be improved.

[0050] As an embodiment of the present application, refer to Figures 5 to 8The deviation prevention mechanism 7 comprises a pushing unit 71, a rack 72, a limiting plate 73, a guide rod 74, a spring 75, a gear 76 and a screw rod 77. The pushing unit 71 is connected with the moving block 43. The rack 72 is connected with the pushing unit 71 and can be pushed by the pushing unit 71. The limiting plate 73, the guide rod 74 and the spring 75 are all installed inside the screen printing plate 3 and connected with the rack 72. The limiting plate 73 is in the shape of a dovetail. An installation groove is formed inside the screen printing plate 3. The rack 72, the limiting plate 73, the guide rod 74, the spring 75 and the gear 76 are all installed in the installation groove. An operation groove is formed in the bottom of the inner wall of the installation groove and is in the shape of a dovetail matching the limiting plate 73. Through the above arrangement, the guiding and positioning of the movement of the rack 72 can be realized, and the rack 72 can move on a fixed line. A circular hole is formed in the limiting plate 73, and the diameter of the circular hole is consistent with the diameter of the guide rod 74. When the rack 72 drives the limiting plate 73 to move in the operation groove, the guide rod 74 will enter the circular hole and simultaneously press the spring 75, buffer the movement of the rack 72, push the limiting plate 73 when the limiting plate 73 and the guide rod 74 are separated, accelerate the resetting speed of the limiting plate 73, and install the gear 76 inside the screen printing plate 3 and engage the gear 76 with the rack 72. The rack 72 will move horizontally under the action of the pushing unit 71. The rack 72 can drive the gear 76 to rotate when moving horizontally. The screw rod 77 is installed on one side of the gear 76. The rotation of the gear 76 can drive the screw rod 77 to rotate, and the rotation of the screw rod 77 can drive the clamping block 8 to move towards the positioning block 2. The limiting plate 73, the guide rod 74, the spring 75, the gear 76 and the screw rod 77 are all symmetrically arranged with the center line of the screen printing plate 3. The screw threads of the two screw rods 77 are opposite in direction. Through the above arrangement, the two clamping blocks 8 can move towards each other, the distance between the two clamping blocks 8 gradually decreases, the clamping of the positioning block 2 can be realized, the connection between the positioning block 2 and the clamping block 8 is in a rectangular shape, the positioning block 2 and the clamping block 8 can be closely attached when the clamping block 8 moves towards the positioning block 2, the support area of the clamping block 8 can be increased, thereby providing additional support and stability, and the inclination or deviation between the positioning block 2 and the clamping block 8 can be avoided.

[0051] In the above scheme, when the silk screen 3 is turned towards the direction of the clothes, 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 towards the direction of the positioning block 2 and clamp the positioning block 2, the positioning block 2 can be attached between the clamping blocks 8, so as to avoid the positioning block 2 from being skewed when printing the clothes, by setting the clamping blocks 8 on both sides of the positioning block 2, the supporting area of the positioning block 2 can be expanded, so that when the center of gravity deviates from the supporting 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 force and skewed or inclined, the effect of printing the clothes can be improved, and errors in printing the clothes can be avoided.

[0052] As an embodiment of the present application, refer to Figures 5 to 8The pushing unit 71 comprises 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. The disc 712 is installed at one end of the rotating shaft 711. When the clamping piece 5 drives the clamped screen printing plate 3 to rotate towards the clothing, the rotating shaft 711 can drive the disc 712 to rotate. The rotating shaft 711 and the rotating seat 44 are concentrically arranged. When the rotating seat 44 drives the clamping piece 5 to rotate by a certain degree, the rotating shaft 711 also drives the disc 712 to rotate by 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 kept in an inclined state when the clothing is not printed, which facilitates the operation of the staff on the screen printing plate 3 and facilitates the disassembly of the screen printing plate 3. The path length of the rotation of the disc 712 is less than the translation length of the rack 72. The length of the guide rod 74 is consistent with the translation length of the limiting plate 73. Through the above arrangement, the rack 72 and the limiting plate 73 can move a certain distance after the disc 712 rotates a certain distance. The path length of the rotation of the disc 712 and the translation distance of the rack 72 are related. The limiting column 713 is installed at one end of the disc 712. The connecting rod 714 is installed at one end of the limiting column 713 and connected with the rack 72. The limiting column 713 and the disc 712 are eccentrically arranged. The connecting rod 714 and the rack 72 are connected. This arrangement is to facilitate the disassembly of the connecting rod 714 and the rack 72, so as to facilitate the replacement of the screen printing plate 3 by the staff. When the disc 712 drives the limiting column 713 to rotate, the limiting column 713 can rotate eccentrically, 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 in a horizontal state, and the bottom end of the rotating seat 44 is attached to the top end of the mounting portion 412.

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. Under the action of the rubber pad (6), the two clamping pieces (5) can clamp the screen printing plate (3). Then, the user places the two clamping blocks (8) at both ends of the positioning block (2). Then, the user presses down the clamped screen printing plate (3). 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). 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). Then, the user continues to press down the screen printing plate (3) to print on the clothing. The user inserts the limiting portion (411) of the movable plate (41) into the dovetail groove of the track (1), and then controls the movable plate (41) to slide on the track (1). When the movable plate (41) moves in front of the garment to be printed, the user aligns the rectangular groove of the screen printing plate (3) with the rubber pad (6), and then controls the rotating rod (42) to rotate through the rotating disk (45). When the rotating rod (42) rotates, it can drive the screw (47) installed on its outer wall to rotate. Since the two screws (4 7) The two movable blocks (43) are arranged in reverse, so that the two movable blocks (43) can be controlled to move toward each other in their respective movable grooves (46). When the movable blocks (43) move, they 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) into the rectangular groove, so that the screen printing plate (3) can be clamped. Then, the connecting rod (714) is clamped with the rack (72), so that the screen printing plate (3) can be prevented from being manually held. When the screen printing plate (3) is clamped, the user presses the screen printing plate (3) downward. When pressing the screen printing plate (3) downward, the user always pays attention to the position of the two clamping blocks (8). When the two clamping blocks (8) are both located on both sides of the positioning block (2), the screen printing plate (3) is pressed downward. When the screen printing plate (3) is pressed downward, the rotating seat (44) is driven to rotate in the moving block (43) through the clamping piece (5). When the rotating seat (44) rotates, it can drive the rotating shaft (711) to rotate. The rotating shaft (711) rotates. When the disc (712) is rotated, the disc (712) can be driven to rotate. Since the limiting post (713) and the disc (712) are eccentrically arranged, the disc (712) can drive the limiting post (713) to rotate eccentrically. When the limiting post (713) rotates from point a to point b, the limiting post (713) can push the rack (72) through the connecting rod (714), and the movement of the rack (72) is limited by the limiting plate (73). At the same time, when the rack (72) is pushed, the guide rod (74) in the installation groove will enter the limiting groove. The circular hole opened inside the positioning plate (73) can guide the movement of the rack (72) and prevent the rack (72) from being deflected during movement. At the same time, the spring (75) can be squeezed to buffer the movement of the rack (72). During the movement, the rack (72) can drive the gear (76) to rotate. When the gear (76) rotates, it can drive the screw (77) to rotate. When the screw (77) rotates, it can drive the two clamping blocks (8) to move toward the positioning block (2). The distance between the two clamping blocks (8) is 1 / 4 of the distance between the two clamping blocks (8). The spacing between the positioning blocks (2) gradually decreases, and the user needs to adjust the spacing between the two clamping blocks (8) and the positioning blocks (2) at the same time, so that the two clamping blocks (8) can be conveniently clamped on the positioning blocks (2). After the clamping blocks (8) clamp the positioning blocks (2), the user continues to press the screen printing plate (3) downward to print on the clothing. By avoiding manual holding of the screen printing plate (3) to print on the clothing, 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. When the printing of the garment 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) to the front of the next garment to be printed, so as to realize the printing of the next garment.
