Description

Technical Field

[0001] The utility model relates to the technical field of clamping structures, in particular to a quick clamping structure for a screen printing frame. Background Art

[0002] Screen printing is a printing process that uses a silk screen as a printing template. During the screen printing process, ink is pushed through the openings of the screen and printed on the surface of the printed object to form a pattern or text. The screen is usually made of polyester fiber, nylon or metal wire. The fineness and mesh size of the screen will vary depending on the printing requirements.

[0003] The screen printing screen frame is a tool used for screen printing, usually made of metal or plastic. Its function is to support the screen and ensure that it fits tightly on the printing surface to achieve accurate printing effects. When installing, the screen frame should face up and then be fixed to the equipment using a fixing structure.

[0004] The silk screen frame in the prior art is usually connected to the equipment by multiple screws, and a lot of operations are required during installation or removal. Especially during installation, it is also necessary to calibrate the position at the same time, and then tighten the screws to complete the installation and fixation of the mesh. The operation is extremely cumbersome, which brings great inconvenience to the replacement operation of the silk screen frame and needs to be improved urgently. Utility Model Content

[0005] The utility model aims to provide a quick clamping structure for a screen printing frame to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A quick clamping structure for a silk-screen screen frame comprises a servo module, on which two movable ends that can move in opposite directions are arranged; both movable ends of the servo module are fixedly connected to a movable plate, one side of the movable plate is slidably connected to a guide rod, one end of the guide rod is fixedly connected to a clamping seat, an end of the guide rod away from the clamping seat extends to the other side of the movable plate and is fixedly connected to a cushion block; a first spring is sleeved on the outer side of the guide rod; a clamping member is arranged on the clamping seat, and the clamping member is used to clamp the screen frame; a locking member is arranged on the top of the clamping seat, and the locking member is used to clamp and fix the screen frame; a transmission member for realizing linkage is arranged between the locking member and the clamping member.

[0008] By adopting the above technical solution, by setting a tightening component, when the screen frame needs to be installed, the two clamping seats can be directly moved toward the side close to each other, and the friction force can be used to preliminarily fix the screen frame. Accompanied by further clamping, the locking component can be transmitted through the transmission component, so that the locking component engages with the screen frame, and then the screen frame can be fixed in a more stable manner, so that the screen frame can be stably fixed and quickly fixed at the same time.

[0009] A further improvement of the technical solution of the utility model is that the clamping component includes a plurality of pressure rods, which are slidably connected to one side of the inner wall of the clamping seat and fixedly connected to a pressure plate, one side of the movable plate is fixedly connected to an L-shaped plate, one end of the pressure rod away from the pressure plate passes through the clamping seat and the L-shaped plate, the outer side of the pressure rod is fixedly connected to a pad, and the outer side of the pressure rod is also covered with a second spring.

[0010] By adopting the above technical solution, after the placement position is adjusted (the screen frame is inserted to the central part between the two clamping seats), the servo module can be controlled to continue working to perform preliminary clamping on the screen frame.

[0011] A further improvement of the technical solution of the utility model is that the locking component includes a plurality of hollow columns, which are all slidably connected to the top of the clamping seat, and the bottom of the hollow columns extends to the interior of the clamping seat, a transmission block is fixedly connected between the tops of the hollow columns, a positioning pin is slidably connected to the bottom of the inner wall of the hollow column, a sliding head is fixedly connected to the top of the positioning pin, the sliding head is slidably connected to the hollow column, and a third spring is fixedly connected between the sliding head and the bottom of the transmission block.

[0012] By adopting the above technical solution, when the hollow column moves downward, if the positioning pin is not facing the screw hole, the third spring will be squeezed, and the position of the screen frame can be properly fine-tuned until the positioning pin faces and is inserted into the screw hole (under the elastic force of the third spring), thereby completing the stable clamping of the screen frame.

[0013] A further improvement of the technical solution of the utility model is that the transmission component includes a connecting groove, the connecting groove is opened on one side of the transmission block, and transmission grooves connected to the inside of the connecting groove are symmetrically opened on both sides of the transmission block. The end of the pressure rod away from the pressure plate is fixedly connected with a linkage plate, and a linkage rod is fixedly connected between the linkage plate and the transmission rod.

[0014] By adopting the above technical solution, during the clamping process of the mesh frame, the pressure plate will squeeze the mesh frame to achieve a certain degree of tightness; at the same time, the mesh frame reacts to the pressure plate, and then pushes the linkage plate to move through the pressure rod, so that the second spring is squeezed, and the linkage rod is driven to move through the linkage plate, and then the transmission rod is driven to move, so as to squeeze the transmission groove, so that the transmission block moves downward, and drives the hollow column to move downward.

[0015] A further improvement of the technical solution of the utility model is that an inclined surface is arranged at one end of the positioning pin away from the sliding head.

[0016] By adopting the above technical solution, when disassembly is required, the servo module is controlled to operate so that the two movable plates move toward the side away from each other, so that the positioning pin can squeeze the inclined surface during the process of moving toward the side away from each other, thereby causing the positioning pin to move upward and automatically leave the corresponding screw hole.

[0017] A further improvement of the technical solution of the utility model is that a rubber pad is arranged on one side of the pressing plate away from the pressing rod.

[0018] By adopting the above technical solution, the clamping of the screen frame by the pressing plate is gentler, thus avoiding damage to the screen frame.

[0019] A further improvement of the technical solution of the utility model is that one side of the two movable plates is fixedly connected to a limiting block.

[0020] The above technical solution can avoid collision between the two movable plates due to misoperation or other reasons when there is no screen frame between the two movable plates.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a quick clamping structure for a screen printing screen frame. By setting a tightening component, when the screen frame needs to be installed, the two clamping seats can be directly moved to the side close to each other, so that the friction force can be used to preliminarily fix the screen frame, and accompanied by further clamping, the locking component can be transmitted by the transmission component, so that the locking component can engage the screen frame, and then the screen frame can be fixed in a more stable manner, so that the screen frame can be stably fixed and quickly fixed at the same time, which greatly improves the installation efficiency of the screen printing screen frame.

[0023] 2. The utility model provides a quick clamping structure for a silk-screen screen frame, which provides an inclined surface at one end of a positioning pin. When disassembly is required, the servo module is controlled to operate so that the two movable plates move toward the side away from each other, so that the positioning pin can squeeze the inclined surface during the movement toward the side away from each other, thereby causing the positioning pin to move upward and automatically leave the corresponding screw hole, so that the screen frame can be quickly disassembled.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the embodiments:

[0033] Example 1

[0034] like Figure 1-Figure 6 As shown, the utility model provides a quick clamping structure for a silk-screen screen frame, comprising a servo module 1, on which two movable ends that can move in opposite directions are arranged; both movable ends of the servo module 1 are fixedly connected with a movable plate 2, one side of the movable plate 2 is slidably connected with a guide rod 4, one end of the guide rod 4 is fixedly connected with a clamping seat 3, and one end of the guide rod 4 extends away from the clamping seat 3 to the other side of the movable plate 2 and is fixedly connected with a cushion block 5; a first spring 6 is sleeved on the outer side of the guide rod 4; a clamping component is provided on the clamping seat 3, and the clamping component is used to clamp the screen frame; a locking component is provided on the top of the clamping seat 3, and the locking component is used to clamp and fix the screen frame; a transmission component for realizing linkage is provided between the locking component and the clamping component.

[0035] In this embodiment, by providing a clamping component, when the screen frame needs to be installed, the two clamping seats 3 can be directly moved toward the side close to each other, and the friction force can be used to preliminarily fix the screen frame. Accompanied by further clamping, the locking component can be transmitted through the transmission component so that the locking component engages with the screen frame, thereby fixing the screen frame in a more stable manner, so that the screen frame can be stably fixed and quickly fixed at the same time, which greatly improves the installation efficiency of the silk screen screen frame.

[0036] like Figure 3 and Figure 4 As shown, preferably, the clamping component includes a plurality of pressure rods 7, which are slidably connected to one side of the inner wall of the clamping seat 3 and fixedly connected to a pressure plate 8, and one side of the movable plate 2 is fixedly connected to an L-shaped plate 9, and one end of the pressure rod 7 away from the pressure plate 8 passes through the clamping seat 3 and the L-shaped plate 9, and the outer side of the pressure rod 7 is fixedly connected to a pad 11, and the outer side of the pressure rod 7 is also covered with a second spring 10.

[0037] In this embodiment, after the placement position is adjusted (the screen frame is inserted to the center between the two clamping seats 3), the servo module 1 can be controlled to continue working to perform preliminary clamping on the screen frame.

[0038] like Figure 3 and Figure 5 As shown, preferably, the locking component includes a plurality of hollow columns 13, each of which is slidably connected to the top of the clamping seat 3, and the bottom of the hollow column 13 extends to the interior of the clamping seat 3. A transmission block 17 is fixedly connected between the tops of the hollow columns 13, a positioning pin 14 is slidably connected to the bottom of the inner wall of the hollow column 13, a sliding head 15 is fixedly connected to the top of the positioning pin 14, the sliding head 15 is slidably connected to the hollow column 13, and a third spring 16 is fixedly connected between the sliding head 15 and the bottom of the transmission block 17.

[0039] In this embodiment, when the hollow column 13 is moved downward, if the positioning pin 14 is not facing the screw hole, the third spring 16 will be squeezed, and the position of the screen frame can be properly fine-tuned until the positioning pin 14 faces and is inserted into the screw hole (under the elastic force of the third spring 16), thereby completing the stable clamping of the screen frame.

[0040] like Figure 2 and Figure 6 As shown, preferably, the transmission component includes a connecting groove 18, the connecting groove 18 is opened on one side of the transmission block 17, and transmission grooves 21 that are connected to the inside of the connecting groove 18 are symmetrically opened on both sides of the transmission block 17. The end of the pressure rod 7 away from the pressure plate 8 is fixedly connected to the linkage plate 12, and a linkage rod 19 is fixedly connected between the linkage plate 12 and the transmission rod 20.

[0041] In this embodiment, during the clamping process of the mesh frame, the pressure plate 8 will squeeze the mesh frame to achieve a certain degree of tightness; at the same time, the mesh frame reacts to the pressure plate 8, and then pushes the linkage plate 12 to move through the pressure rod 7, so that the second spring 10 is squeezed, and the linkage plate 12 drives the linkage rod 19 to move, and then drives the transmission rod 20 to move, so as to squeeze the transmission groove 21, so that the transmission block 17 moves downward, and drives the hollow column 13 to move downward.

[0042] like Figure 4 and Figure 5As shown, preferably, an inclined surface 22 is provided at one end of the positioning pin 14 away from the sliding head 15 , and the two inclined surfaces 22 are located on the opposite sides of the two positioning pins 14 .

[0043] In this embodiment, when disassembly is required, the servo module 1 is controlled to work so that the two movable plates 2 move away from each other, so that the positioning pin 14 can squeeze the inclined surface 22 during the movement toward the side away from each other, thereby causing the positioning pin 14 to move upward and automatically leave the corresponding screw hole.

[0044] Example 2

[0045] On the basis of Example 1, the utility model provides a technical solution: preferably, a rubber pad is provided on the side of the pressing plate 8 away from the pressing rod 7 .

[0046] In this embodiment, the clamping of the screen frame by the pressing plate 8 is made gentler, thus avoiding damage to the screen frame.

[0047] Example 3

[0048] like Figure 1 and Figure 2 As shown, based on Example 2, the utility model provides a technical solution: preferably, one side of the two movable plates 2 is fixedly connected to a limiting block.

[0049] In this embodiment, when there is no screen frame between the two movable plates 2, collision between the two movable plates 2 due to misoperation or other reasons is avoided.

[0050] The following is a detailed description of the working principle of the silk screen frame quick clamping structure.

[0051] like Figure 1-Figure 6As shown, according to the size of the screen frame, pre-clamping is first performed, and the servo module 1 is controlled to work, so that the two movable plates 2 drive the clamping to move 3 until the screen frame can be placed between the two clamping seats 3. At this time, the screen frame can be flexibly taken and placed between the clamping seats 3. After the placement position is adjusted (the screen frame is inserted to the central part between the two clamping seats 3), the servo module 1 can be controlled to continue working to further clamp the screen frame; during the process, the pressing plate 8 will squeeze the screen frame to achieve a certain degree of tightness; at the same time, the screen frame reacts to the pressing plate 8, and then pushes the linkage plate 12 through the pressing rod 7. The second spring 10 is squeezed, and the linkage rod 19 is driven to move through the linkage plate 12, thereby driving the transmission rod 20 to move, so as to squeeze the transmission slot 21, so that the transmission block 17 moves downward, and drives the hollow column 13 to move downward. At this time, when the positioning pin 14 is facing the screw hole on the screen frame, the positioning pin 14 will be directly inserted into the screw hole to achieve fixation; and when the positioning pin 14 is not facing the screw hole, the third spring 16 will be squeezed, and the position of the screen frame can be properly fine-tuned until the positioning pin 14 is facing and inserted into the screw hole, and the stable clamping of the screen frame can be completed.

[0052] When disassembly is required, it is only necessary to control the servo module 1 to work so that the two movable plates 2 move to the side away from each other. At the initial stage of the movement, the clamping seat 3 cannot move in the direction of the movable plate 2 due to the obstruction of the positioning pin 14. At this time, the movable plate 2 will slide relative to the clamping seat 3 on the axial direction of the guide rod 4, squeezing the first spring 6, thereby applying pressure to the cushion block 5, and making the clamping seat 3 have a tendency to move through the pressure rod 7, so that the positioning pin 14 can move upward through the inclined surface 22, and then automatically leave the corresponding screw hole, and after the positioning pin 14 leaves the screw hole, the clamping seat 3 is close to the movable plate 2 under the elastic force of the first spring 6, and at the same time, because the positioning pin 14 releases the plug-in positioning of the screw hole, the screen frame can be directly removed, which greatly improves the efficiency of disassembly and assembly of the screen frame.

[0053] The servo module 1 is composed of a servo motor, a bidirectional lead screw and a slider, and when working, the movable plate 2 moves in the opposite direction with the slider with the same displacement.

[0054] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
