Description

Technical Field

[0001] This utility model belongs to the field of printing equipment technology, and specifically relates to a printing positioning device. Background Technology

[0002] A printing press is a machine that uses a pre-made printing plate to reproduce text and images. Depending on the type of printing plate used, printing presses are classified as letterpress printing presses, offset printing presses, gravure printing presses, screen printing presses, and special printing presses. A printing press is a machine for printing text and images. During the printing process, a positioning device is needed to position the substrate to prevent it from shifting. Thicker substrates are more prone to shifting, which can lead to printing quality problems. Currently, the common methods for positioning substrates are fixed baffles, positioning pins, or adhesive positioning plates. These are inconvenient for adjusting substrates of different sizes and thicknesses and may scratch the edges of the substrate, affecting the quality of the finished print. While adhesive positioning plates are easy to adjust, they require frequent replacement of consumables, which is cumbersome. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a printing positioning device, which aims to solve the problems of existing printing positioning devices being inconvenient to adjust for substrates of different sizes and thicknesses, and potentially scratching the edges of the substrate, thus affecting the quality of the printed product.

[0004] To solve the above-mentioned technical problems, this utility model provides a printing positioning device, which includes a mounting frame, a precision positioning component installed inside the mounting frame, the precision positioning component being used to firmly fix the printing substrate, the precision positioning component being adaptable to fixing printing substrates of different sizes, and a quick positioning component placed above the mounting frame, the quick positioning component being used to quickly attract and fix the printing substrate containing ferromagnetic materials.

[0005] Furthermore, the precision positioning component includes two positioning baffles symmetrical about the upper surface of the mounting frame. The upper surface of the mounting frame has two sets of guide grooves, each guide groove containing a guide block. The upper surface of each guide block is fixedly connected to the bottom surface of the positioning baffle. A connecting rod is rotatably connected to the bottom surface of each guide block. The top wall of the mounting frame has a slot containing two locking blocks. A connecting rod is rotatably connected to the left and right sides of each locking block. The other end of each connecting rod is rotatably connected to the bottom surface of its corresponding guide block. A forward / reverse screw is rotatably connected to the rear wall of the mounting frame. The front end of the forward / reverse screw penetrates the front of the mounting frame and is rotatably connected to it. The outer surface of the forward / reverse screw is threadedly connected to the two locking blocks.

[0006] Furthermore, the positioning baffle has a smooth bottom surface, which allows the two positioning baffles to slide more smoothly when moving left and right.

[0007] Furthermore, rubber strips are fixedly connected to the sides of the two positioning baffles that are close to each other. The rubber strips can clamp and fix the substrate more firmly and avoid damage to the substrate.

[0008] Furthermore, the threads on the surface of the forward and reverse lead screw are symmetrical about the center line of the upper surface of the mounting frame, which allows the two locking blocks to move synchronously in opposite directions when they are moving.

[0009] Furthermore, the rapid positioning component includes a magnetic block embedded in the upper part of the mounting frame, which has a smooth surface. A set of magnetic strips is fixedly connected to the upper surface of each positioning baffle. A pressure rod is placed above the magnetic strips. The pressure rod is made of low-carbon steel, and a semi-circular elastic plate is fixedly connected to the bottom surface of the pressure rod. The semi-circular elastic plate has a C-shaped cross-section, which can quickly fix thin and magnetic substrates.

[0010] Furthermore, the upper surface of the magnetic block is close to the surface of the mounting frame, and the magnetic force of the magnetic block can penetrate the upper surface of the mounting frame, thus avoiding the situation where the magnetic force of the magnetic block cannot attract the magnetic substrate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention provides power for the forward and reverse movement of two locking blocks by rotating a forward and reverse screw. Through a linkage principle, when the two locking blocks move away from each other, two sets of guide blocks drive two positioning baffles to move stably towards each other. A rubber strip presses and fixes the edge of the substrate surface as the two positioning baffles move towards each other. A guide groove allows for rapid adjustment of the distance between the two positioning baffles, enabling the device to adapt to and fix substrates of different sizes.

[0013] This invention utilizes a magnetic block. Under the influence of the magnetic force of the magnetic block, if the substrate itself contains ferromagnetic materials (such as some paper or metal foil), the substrate can be directly placed on the surface of the mounting frame and quickly fixed under the influence of the magnetic force of the mounting frame. Then, through the mutual attraction between the magnetic strip and the pressure rod, when the pressure rod is placed on the surface of the magnetic strip, it will be attracted to the surface of the magnetic strip due to the magnetic force. At this time, the semi-circular elastic plate will press down to achieve a secondary and rapid fixation of the substrate. Attached Figure Description

[0021] This specific embodiment is a printing positioning device, the structural diagram of which is shown below. Figures 1-6As shown, the device includes...

[0022] like Figure 1 and Figure 3 As shown: The device includes a mounting frame 3, a precision positioning component 1, which is installed inside the mounting frame 3 and is used to firmly fix the substrate. The precision positioning component 1 can be adapted to fix substrates of different sizes. A quick positioning component 2 is placed on top of the mounting frame 3 and is used to quickly attract and fix the substrate containing ferromagnetic materials.

[0023] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown: Precision positioning component 1 includes positioning baffles 4. There are two positioning baffles 4, which are symmetrical about the upper surface of the mounting frame 3. The upper surface of the mounting frame 3 has two sets of guide grooves 7. Each guide groove 7 has a guide block 8 inside it. The upper surface of each set of guide blocks 8 is fixedly connected to the bottom surface of the positioning baffles 4. The bottom surface of each guide block 8 is rotatably connected to a connecting rod 9. The top wall of the mounting frame 3 has a slot 12. The slot 12 has two locking blocks 11 inside it. The left and right sides of each locking block 11 are rotatably connected to a connecting rod 9. The other end of each connecting rod 9 is rotatably connected to the bottom surface of the corresponding guide block 8. The rear wall of the mounting frame 3 is rotatably connected to a forward and reverse screw 10. The front end of the forward and reverse screw 10 passes through the front of the mounting frame 3 and is rotatably connected to the mounting frame 3. The outer surface of the forward and reverse screw 10 is threadedly connected to the two locking blocks 11.

[0024] like Figure 1 and Figure 3 As shown: The positioning baffle 4 has a smooth bottom surface, which makes the two positioning baffles 4 slide more smoothly when moving left and right.

[0025] like Figure 2 As shown: Rubber strips 5 are fixedly connected to the sides of the two positioning baffles 4 that are close to each other. The rubber strips 5 can clamp and fix the substrate more firmly and avoid damage to the substrate.

[0026] like Figure 2 , Figure 3 and Figure 6 As shown: the threads on the surface of the forward and reverse lead screw 10 are symmetrical about the center line of the upper surface of the mounting frame 3, which allows the two locking blocks 11 to move in opposite directions synchronously when they are moving.

[0027] like Figure 1As shown: The quick positioning component 2 includes a magnetic block 13, which is embedded in the upper part of the mounting frame 3. The mounting frame 3 has a smooth surface. A set of magnetic strips 6 are fixedly connected to the upper surface of each positioning baffle 4. A pressure rod 14 is placed above the magnetic strips 6. The pressure rod 14 is made of low carbon steel. A semi-circular elastic plate 15 is fixedly connected to the bottom surface of the pressure rod 14. The cross-sectional shape of the semi-circular elastic plate 15 is C-shaped, which can quickly fix thin and magnetic substrates.

[0028] like Figure 1 As shown: The upper surface of the magnetic block 13 is close to the surface of the mounting frame 3, and the magnetic force of the magnetic block 13 can penetrate the upper surface of the mounting frame 3, thus avoiding the situation where the magnetic force of the magnetic block 13 cannot attract the magnetic substrate.

[0029] Working Principle: When it is necessary to fix a substrate containing magnetic material, simply place the substrate directly on the surface of the mounting frame 3. Under the influence of the magnetic force of the mounting frame 3, it can be quickly fixed. Then, through the mutual attraction between the magnetic strip 6 and the pressure rod 14, when the pressure rod 14 is placed on the surface of the magnetic strip 6, it will be attracted to the surface of the magnetic strip 6 by the magnetic force. At this time, the semi-circular elastic plate 15 will be pressed down and deformed to achieve a secondary quick fixation of the substrate. Moreover, it can prevent the substrate from being crushed when fixing it. When fixing ordinary thicker substrates, the overall adjustment of the precision positioning component 1 can be made according to the size of the substrate. When the object is small, simply rotating the front end of the forward and reverse screw 10 in the forward direction will move the two locking blocks 11 away from each other. When the two locking blocks 11 are away from each other, the two sets of guide blocks 8 can drive the two positioning baffles 4 to move stably towards each other. Through the rubber strip 5, when the two positioning baffles 4 move towards each other, the rubber strip 5 will press and fix the edge of the substrate surface. Similarly, rotating the front end of the forward and reverse screw 10 in the opposite direction will move the two positioning baffles 4 away from each other, thereby achieving the effect of quickly adjusting the distance between the two positioning baffles 4, and further facilitating the fixing of substrates of different sizes.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
