Description

Technical Field

[0001] This utility model relates to the field of screen printing equipment technology, and in particular to a screen printing machine frame. Background Technology

[0002] When screen printing machines screen print on different workpieces, different screens (frames) are required. Currently, almost all semi-automatic and vacuum screen printing machines use a free insertion method for the screen frame installation. The screen frame is then moved left and right to the center of the screen printing machine and back and forth to the center of the table by feel. Next, the workpiece is attached to the film, and the graphic on the screen frame is screen printed onto the film on the worktable. The back and forth and left and right deviations of the worktable are then adjusted according to the deviation between the film and the workpiece. After repeated screen printing and adjustments, the ink holes and screen printing holes are aligned to complete the manual alignment. Furthermore, when the screen frame needs to be wiped or pulled, it needs to be pulled out and put back, requiring repeated operations. This is inconvenient, time-consuming, and seriously reduces production efficiency. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0039] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0040] Reference Figure 1 and Figure 3 This utility model discloses a screen printing machine frame, including: a frame 11 and a front positioning plate 16, a left support plate 12 and a right support plate 13, all disposed on the frame 11, with the left support plate 12 and the right support plate 13 distributed left and right.

[0041] The frame 11 is used to connect to the frame of the screen printing machine. The frame 11 is fixed on the frame and supports the front positioning plate 16, the left support plate 12, and the right support plate 13. The left support plate 12 and the right support plate 13 are both mounted on the frame 11 via the first sliding mechanism 14. The left support plate 12 and the right support plate 13 are each provided with a plurality of first clamping mechanisms 15. The first clamping mechanisms 15 are used to clamp the screen frame 1. The sliding direction of the first sliding mechanism 14 is the front-back direction, so that the screen frame 1 on the left support plate 12 and the right support plate 13 can move between the table of the screen printing machine and the feed port of the screen printing machine. The front positioning plate 16 is located in front of the left support plate 12 and the right support plate 13. The front positioning plate 16 is used to prevent the screen frame 1 from moving forward, so as to position the screen frame 1.

[0042] The two first sliding mechanisms 14 enable the left support plate 12 and the right support plate 13 to move along the front-back direction on the frame 11. The screen printing machine table and the screen printing machine inlet are distributed front to back, and the left support plate 12 and the right support plate 13 are located above the screen printing machine table and the screen printing machine inlet, so that the left support plate 12 and the right support plate 13 can move to the top of the screen printing machine table and to the vicinity of the screen printing machine inlet.

[0043] Pull back the left support plate 12 and the right support plate 13. When the left support plate 12 and the right support plate 13 are moved close to the feed port of the screen printing machine, the screen frame 1 can be easily and quickly installed on the left support plate 12 and the right support plate 13. The screen frame 1 can be removed from the left support plate 12 and the right support plate 13 to clean the screen frame 1. There is no need for the operator to climb into the machine box of the screen printing machine to work, which improves the efficiency and safety of operation.

[0044] Push the left support plate 12 and the right support plate 13 forward. The left support plate 12 and the right support plate 13 can carry the screen frame 1 to the top of the screen printing machine table. When the screen frame 1 abuts against the front positioning plate 16, the front positioning plate 16 blocks the screen frame 1 from moving forward to achieve the positioning of the screen frame 1. The screen frame 1 moves to the correct position so that the screen frame 1 can screen print on the workpiece on the screen printing machine table.

[0045] The left support plate 12 and the right support plate 13 have the same structure.

[0046] Reference Figure 1 and Figure 5 In some embodiments, the left support plate 12 includes a left side portion 121 and a left support portion 122 located at the lower end of the left side portion 121. The length direction of the left side portion 121 and the left support portion 122 is the front-to-back direction. The left end of the left support portion 122 is connected to the lower end face of the left side portion 121. The left side portion 121 and the left support portion 122 are L-shaped. The left side portion 121 is connected to the frame 11 through the first sliding mechanism 14. The right end of the left support portion 122 is used to support the left end of the mesh frame 1.

[0047] The right support plate 13 includes a right side portion and a right support portion located at the lower end of the right side portion. The length direction of the right side portion and the right support portion is the front-to-back direction. The right end of the right support portion is connected to the lower end face of the right side portion. The right side portion and the right support portion are L-shaped. The right side portion is connected to the frame 11 through the first sliding mechanism 14. The left end of the right support portion is used to support the right end of the mesh frame 1. The left support portion 122 and the right support portion respectively support the left and right ends of the mesh frame 1, so that the mesh frame 1 is balanced by force.

[0048] Reference Figure 1 and Figure 2 In some embodiments, the left support plate 12 and the right support plate 13 are provided with a plurality of second clamping mechanisms 17. The plurality of first clamping mechanisms 15 and the plurality of second clamping mechanisms 17 are used to clamp the mesh frame 1 to ensure that the mesh frame 1 is firmly on the left support plate 12 and the right support plate 13.

[0049] The first sliding mechanism 14 includes a first slide rail and a first slider that cooperate with each other. The length direction of the first slide rail is the front-to-back direction. The first slide rail and the first slider are respectively connected to the frame 11 and the left support plate 12, that is, the first slider is connected to the left side of the left side portion 121. The first slide rail and the first slider of the other first sliding mechanism 14 are respectively connected to the frame 11 and the right support plate 13, that is, the first slider is connected to the right side of the right side portion.

[0050] Both the left support plate 12 and the right support plate 13 are equipped with second slide rails 1212, with the length direction of the second slide rails 1212 being the front-to-back direction. The first clamping mechanism 15 is connected to the second slide rail 1212 via a second slider, making the front-to-back position of the first clamping mechanism 15 adjustable, allowing the first clamping mechanism 15 to clamp the left end of the mesh frame 1 at different front and back positions. Similarly, the second clamping mechanism 17 is also connected to the second slide rail 1212 via a second slider, making the front-to-back position of the second clamping mechanism 17 adjustable.

[0051] It is understood that the first clamping mechanism 15 includes a first cylinder, the cylinder body of the first cylinder is connected to the second slider on the left support plate 12, the first cylinder is located above the left support part 122, the piston rod of the first cylinder faces downward, and the piston rod of the first cylinder is used to press the mesh frame 1 onto the left support part 122, so as to fix the left end of the mesh frame 1 onto the left support plate 12.

[0052] The second clamping mechanism 17 is a bolt or screw, which is threadedly connected to the second slider on the left support plate 12. The bolt or screw is located above the left support portion 122, and the lower end of the bolt or screw is used to press the mesh frame 1 onto the left support portion 122 to fix the left end of the mesh frame 1 onto the left support plate 12.

[0053] The left support 122 is provided with a first scale, the length direction of the first scale is the front-to-back direction, and the front-to-back position of the mesh frame 1 on the left support 122 can be accurately determined by the first scale.

[0054] Reference Figure 5 In some embodiments, the left side portion 121 is provided with a first pad 1211 for abutting against the left end face of the wire frame 1. The left end face of the wire frame 1 abuts against the left side portion 121 through the first pad 1211. There is no direct friction between the left end face of the wire frame 1 and the left side portion 121, which can reduce the wear of the left end face of the wire frame 1 and the left side portion 121.

[0055] A first pad 1211 is provided on the right side for abutting against the right end face of the wire mesh frame 1. The right end face of the wire mesh frame 1 is abutted against the right side by the first pad 1211. It is conceivable that the first pad 1211 can be made of wear-resistant or elastic material.

[0056] The front positioning plate 16 has multiple first oblong holes, the length of which is in the front-to-back direction. The front end of the frame 11 has multiple first fasteners, which pass through the first oblong holes and are threadedly connected to the front end of the frame 11. Loosening the first fasteners adjusts the front-to-back position of the front positioning plate 16, while tightening them fixes the front positioning plate 16 to the front end of the frame 11. Adjusting the front-to-back position of the front positioning plate 16 adjusts the front-to-back positioning position of the mesh frame 1.

[0057] Reference Figure 1 In some embodiments, the rear side of the front positioning plate 16 is provided with a second pad 161 for abutting against the wire mesh frame 1. The rear side of the front positioning plate 16 abuts against the front end face of the wire mesh frame 1 through the second pad 161, and the front positioning plate 16 does not abut against the front end face of the wire mesh frame 1, which can reduce the wear between the front positioning plate 16 and the front end face of the wire mesh frame 1. The second pad 161 may be made of wear-resistant or elastic material.

[0058] Reference Figure 2 and Figure 4 In some embodiments, the screen printing machine frame also includes a buffer assembly 18 and a positioning block 19 distributed in the front-back direction. One of the buffer assembly 18 and the positioning block 19 is disposed on the frame 11 and the other is disposed on the left support plate 12. The buffer assembly 18 and the positioning block 19 are used to prevent the screen frame 1 from moving backward in order to position the screen frame 1.

[0059] When the left support plate 12 moves backward, the buffer component 18 and the positioning block 19 abut against each other, preventing the left support plate 12 from moving backward further, thus positioning the left support plate 12 and the mesh frame 1 and preventing the left support plate 12 and the mesh frame 1 from moving backward away from the frame 11.

[0060] In this embodiment, buffer components 18 are provided at both the left and right ends of the frame 11, and positioning blocks 19 are provided on both the left support plate 12 and the right support plate 13. The buffer component 18 at the left end of the frame 11 cooperates with the positioning block 19 on the left support plate 12, and the buffer component 18 at the right end of the frame 11 cooperates with the positioning block 19 on the right support plate 13.

[0061] Reference Figure 1 In some embodiments, the screen printing machine frame further includes a magnetic attractor 21 and a magnetically attracted component 22. One of the magnetic attractor 21 and the magnetically attracted component 22 is disposed on the left support plate 12 or the right support plate 13, and the other is disposed at the front end of the frame 11. When the left support plate 12, the right support plate 13 and the screen frame 1 move forward and are positioned by the front positioning plate 16, the magnetic attractor 21 and the magnetically attracted component 22 are attracted together, so that the left support plate 12, the right support plate 13 and the screen frame 1 are stably fixed on the frame 11.

[0062] It is understandable that one of the magnetic attracting component 21 and the magnetically attracted component 22 is an electromagnetic block, and the other is an iron block.

[0063] In this embodiment, the front ends of the left support plate 12 and the right support plate 13 are provided with magnetic attracting components 22, and the left and right sides of the front end of the frame 11 are provided with magnetic attracting components 21. The magnetic attracting component 22 at the front end of the left support plate 12 cooperates with the magnetic attracting component 21 on the left side of the front end of the frame 11, and the magnetic attracting component 22 at the front end of the right support plate 13 cooperates with the magnetic attracting component 21 on the right side of the front end of the frame 11.

[0064] Reference Figure 1 and Figure 5 In some embodiments, the screen printing machine frame also includes a first left-right linear drive mechanism 23 disposed on the frame 11 and a positioning post 231 disposed on the output end of the first left-right linear drive mechanism 23. The first left-right linear drive mechanism 23 is used to drive the positioning post 231 to connect in the left-right direction. The front and rear ends of the left support plate 12 are respectively provided with a first positioning hole 123 and a second positioning hole 124 for the positioning post 231 to be inserted.

[0065] The left support plate 12, the right support plate 13 and the screen frame 1 move forward. When the screen frame 1 abuts against the front positioning plate 16, the positioning post 231 is inserted into the second positioning hole 124, so that the left support plate 12 is supported on the frame 11, that is, the screen frame 1 is supported above the table of the screen printing machine.

[0066] The left support plate 12, the right support plate 13 and the screen frame 1 move backward. When the screen frame 1 is closest to the feed port of the screen printing machine, the positioning post 231 is inserted into the first positioning hole 123, thereby locking the left support plate 12 onto the frame 11, that is, locking and supporting the screen frame 1 at a position close to the feed port of the screen printing machine.

[0067] The first positioning hole 123 is a second oblong hole. The length direction of the first positioning hole 123 is the front-back direction, so that the left support plate 12 can be fitted on the positioning post 231 and can move a certain distance in the front-back direction, that is, the left support plate 12 can be adjusted in the front-back position.

[0068] It is conceivable that the frame 11 has a first left-right linear drive mechanism 23 on both the left and right sides, and the two first left-right linear drive mechanisms 23 are symmetrically arranged. The output end of the first left-right linear drive mechanism 23 on the left side of the frame 11 faces to the right, and the output end of the first left-right linear drive mechanism 23 on the right side of the frame 11 faces to the left. The right support plate 13 has a first positioning hole 123 and a second positioning hole 124 for the positioning pin 231 to be inserted at its front and rear ends, respectively. The first positioning holes 123 on the left and right sides are symmetrically arranged, and the second positioning holes 124 on the left and right sides are symmetrically arranged.

[0069] Reference Figure 1 In some embodiments, the frame 11 includes a square frame 111 and a left side plate 112 and a right side plate 113 both disposed on the square frame 111. The frame 11 is connected to the frame through the square frame 111. The left side plate 112 is connected to the left support plate 12 through a first sliding mechanism 14, and the right side plate 113 is connected to the right support plate 13 through another first sliding mechanism 14.

[0070] The frame 111 has a second scale, the length of which is in the left-right direction. By observing the second scale, the position of the frame 1 in the left-right direction can be easily determined.

[0071] In some embodiments, the screen printing machine frame further includes a second left-right linear drive mechanism 24 disposed on the frame 111 and a push rod 241 disposed on the output end of the second left-right linear drive mechanism 24. The left side plate 112 is slidably disposed on the frame 111 in the left-right direction. The push rod 241 is connected to the left support plate 12. The second left-right linear drive mechanism 24 drives the left support plate 12 to move in the left-right direction through the push rod 241 to adjust the left-right position of the left support plate 12.

[0072] In this embodiment, a second left-right linear drive mechanism 24 is provided on both the left and right sides of the frame 111. The output end of the second left-right linear drive mechanism 24 on the left side of the frame 111 faces to the right, and the output end of the second left-right linear drive mechanism 24 on the right side of the frame 111 faces to the left. The push rod 241 on the second left-right linear drive mechanism 24 on the right side of the frame 111 is connected to the right support plate 13.

[0073] The front and rear ends of the left support plate 12 and the front and rear ends of the right support plate 13 are fixedly connected to the frame 111 by clamping cylinders. Clamping cylinders are common components and will not be described in detail here.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
