Description

Technical Field

[0001] The utility model relates to the technical field of combined self - tensioning screen printing frames, in particular to a combined self - tensioning screen printing frame. Background Art

[0002] At present, screen printing technology has been widely applied in various industries, such as handicraft printing, clothing pattern printing, PCB manufacturing character printing, etc. For traditional screen plates, stretching the screen is a relatively cumbersome process. Traditional screen stretching machines are bulky and expensive. And the screen frame usually fixes the screen by using glue and L - shaped nails to maintain the tension. After several times of removing the screen, the screen frame can no longer be used. Moreover, generally, the screen frame is made of wooden frame or aluminum alloy frame, and the size of the screen frame cannot be changed. In order to print objects of various shapes, multiple screen frames of different sizes need to be prepared.

[0003] Publication (Announcement) No. CN204845106U discloses a combined self - tensioning screen printing frame, which includes a fixed outer frame, a movable inner frame, a rubber pressing strip, a screen, a connecting screw rod and a butterfly nut. The screen to be stretched is fixed on the movable inner frame with a groove by the rubber pressing strip. The movable inner frame is connected to the fixed outer frame by the connecting screw rod. When the butterfly nuts on the outer frame are tightened, the screen is tightened and fixed on the outer frame.

[0004] When in use, during the process of fixing the inner frame of the device, it is necessary for the staff to turn multiple butterfly nuts to drive the screw rod to move, making it inconvenient to clamp the inner frame. And the size of the inner frame cannot exceed the size of the outer frame, otherwise it is difficult to install the inner frame, making the use range of the device relatively limited. Therefore, we propose a combined self - tensioning screen printing frame. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a combined self - tensioning screen printing frame.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A combined self - tensioning screen printing frame, including an outer frame, a connecting piece is fixedly installed on one side of the outer frame, a connecting frame is arranged on one side of the connecting piece, a spring is fixedly installed inside the outer frame, a sliding block is fixedly installed on the outer side of one end of the spring, and a first locking block is fixedly installed on one side of the sliding block; an expansion component, the expansion component is installed on the connecting frame; a connecting component, the connecting component is installed on the outer frame and the sliding block.

[0008] Preferably, the expansion component includes a locking screw rod and a control handle. The locking screw rod is threadedly installed on the left and right sides inside the connection frame, and the control handle is fixedly installed on the outer side of one end of the locking screw rod.

[0009] By adopting the above technical solution, multiple outer frames can be expanded into different sizes after connection, and can be locked by the locking screw rod after expansion, so that the outer frames are not likely to become loose.

[0010] Preferably, the connection component includes a connection block, an inner frame, a second locking block, a first pulling handle, a sliding rod, and a second pulling handle. The connection block is fixedly installed on one side of the sliding block. The inner frame is arranged between one side of the outer frame.

The first pulling handle is fixedly installed on one side of the connection block. The sliding rod is fixedly installed on one side of the first pulling handle. The second pulling handle is slidably installed on the outer side of the sliding rod.

[0011] By adopting the above technical solution, the inner frame can be quickly fixed by the second locking block above, and the first locking block can directly slide into the inner side of the second locking block, making the installation of the device relatively convenient.

[0012] Preferably, a limiting groove is formed on the front side of the connecting piece, and anti-slip pads are arranged on one side of the locking screw rod and the limiting groove.

[0013] By adopting the above technical solution, the anti-slip pads result in a large frictional force after the locking screw rod abuts against the limiting groove, so that the connecting piece and the connection frame are not easily separated.

[0014] Preferably, the outer frame is in an L shape, an installation groove is formed on one side of the outer frame, and the outer diameter of the second locking block is the same as the inner diameter of the installation groove.

[0015] By adopting the above technical solution, the installation groove facilitates the second locking block to quickly slide into the inner side of the outer frame.

[0016] Preferably, a locking groove is formed on one side of the second locking block, and the first locking block fits with the locking groove.

[0017] By adopting the above technical solution, the locking groove facilitates the first locking block to lock the second locking block after sliding.

[0018] Preferably, sliding grooves are formed on the left and right sides of the connection frame, the outer diameter of the limiting groove is the same as the inner diameter of the sliding groove, threaded holes are formed on the left and right sides of the front side of the connection frame, and the locking screw rod is threadedly installed inside the threaded holes.

[0019] By adopting the above technical solution, it is convenient to connect the connecting piece and the connecting frame, and it is not easy to generate gaps, so that jitter is not likely to occur after connection.

[0020] Preferably, a sliding groove is formed on one side of the outer frame, the spring is fixedly installed on the inner wall of one side of the sliding groove, and the sliding block and the connecting block are slidably installed inside the sliding groove.

[0021] By adopting the above technical solution, after the first pulling handle, the sliding rod and the second pulling handle are pulled, multiple connecting blocks can be simultaneously pulled to move, the connecting blocks can control the sliding block, so that the sliding block can drive the first locking block to move after sliding, and it is not easy to cause interference when the second locking block slides into the inside of the installation groove, and after the second locking block slides in, the control of the first pulling handle or the second pulling handle can be released, so that the spring can drive the sliding block and the first locking block to slide into the inside of the locking groove.

[0022] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0023] (1) For a combined self-tensioning screen printing frame of the present utility model, by arranging the expansion assembly, the inner frame is placed in the middle of multiple outer frames, the distance between the multiple outer frames is adjusted according to the size of the inner frame, the outer frame slides into the inside of the connecting frame through the connecting piece, and after the distance size is adjusted, the control handle is rotated to drive the locking screw rod to move, so that the locking screw rod abuts against the limiting groove, thereby making it not easy for the outer frame and the connecting frame to loosen, and making the device adaptable to various inner frames of different sizes;

[0024] (2) For a combined self-tensioning screen printing frame of the present utility model, by arranging the connecting assembly, when connecting and fixing the inner frame, after adjusting the distance between the outer frames according to its size, the distance between the second pulling handle and the first pulling handle can be adjusted through the sliding rod, so that when either the first pulling handle or the second pulling handle is pulled on any side, the connecting blocks, the sliding block and the first locking block on both sides can be driven to slide, so that the second locking block can slide into the inside of the installation groove, and the first locking block can lock the second locking block, making the connection and disassembly of the device relatively convenient.
