Description

Technical Field

[0001] This utility model relates to the field of paper mounting technology, and in particular to an easy-to-operate paper mounting positioning mechanism. Background Technology

[0002] Mounting is a process that uses the natural tension of paper to adhere wet paper to the surface of objects such as cardboard or wood, creating a smooth surface after drying. The dried paper is very flat and is generally used in the preliminary preparation for drawing and painting.

[0003] Currently, when mounting paper by hand, most people lay the paper flat on the surface of a solid wood board, roughly align the center of the image on the paper with the center of the solid wood board manually, spray water on the paper to wet it, and then stick it to the surface of the solid wood board. However, due to the poor accuracy of the manual positioning method, the center of the paper and the center of the board are often significantly offset, and the paper is prone to being laid flat and tilted, which affects the quality of subsequent mounting.

[0004] Therefore, it is necessary to provide an easy-to-operate paper mounting and positioning mechanism to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easy-to-operate paper mounting and positioning mechanism.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an easy-to-operate paper mounting positioning mechanism, including a base, a slot on the top of the base, a placement plate inside the slot, two adjusting components at the bottom of the placement plate, two sets of clamping plates on the placement plate, two sliding grooves on the top of the base, two positioning plates slidably connected inside the two sliding grooves, a magnet fixedly embedded inside one of the positioning plates, two limiting plates magnetically connected to one side of the positioning plate, pins movably inserted on opposite sides of the two positioning plates, several insertion holes inside one of the sliding grooves, and a lifting component for adjusting the height of the placement plate on the base. The several insertion holes are arranged in a linear array. Since most of the paper used in existing paper mounting is made of materials such as Xuan paper, and the length and width of the paper are limited, while the distance between the insertion holes is small, and the distance between some insertion holes is adapted to the length and width of some paper, the two sliding grooves are opened opposite each other.

[0007] As a further description of the above technical solution:

[0008] One of the positioning plates has a positioning scale on its top, and the pin is adapted to the insertion hole. By setting the positioning scale, the moving length and position of the two limiting plates can be confirmed, and the relative moving distance of the two limiting plates can be effectively confirmed.

[0009] As a further description of the above technical solution:

[0010] The bottom of the placement plate is fixedly connected to a connecting frame, and four clearance slots are provided on the placement plate.

[0011] As a further description of the above technical solution:

[0012] Each set of clamping plates consists of two plates, and the four clamping plates are slidably connected inside the four clearance slots.

[0013] As a further description of the above technical solution:

[0014] The adjustment assembly includes a bidirectional screw rotatably connected inside the connecting frame. Two push rods are threadedly connected to the outer surface of the bidirectional screw. The two push rods are fixedly connected to two clamping plates respectively. Four guide rods are fixedly connected to the connecting frame. The four guide rods are movably connected to the two push rods respectively. Although the bidirectional screw is rotatably connected to the connecting frame, both ends of the bidirectional screw are rotatably connected to the bottom of the placement plate.

[0015] As a further description of the above technical solution:

[0016] A collecting plate is fixedly connected to the bottom of the inner wall of the groove, and a drain pipe is provided on the back of the base. Through the setting of the collecting plate and the drain pipe, excess water that drips into the groove during the paper mounting process can be collected and discharged.

[0017] As a further description of the above technical solution:

[0018] Guide grooves are provided on both the front and back sides of the slotted inner wall. Guide blocks are slidably connected inside the two guide grooves. The two guide blocks are fixedly connected to the bottom of the placement plate. The guide grooves and guide blocks are inclined to prevent water from accumulating inside or on top.

[0019] As a further description of the above technical solution:

[0020] The lifting assembly includes a threaded groove on the top of the base, a threaded block is threadedly connected inside the threaded groove, a connecting plate is rotatably connected to the top of the threaded block, and the connecting plate is fixedly connected to the top of the placement plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. Compared with the prior art, this easy-to-operate paper mounting positioning mechanism, through the setting of a base, a placement plate, a clamping plate, a positioning plate, a limiting plate, a positioning scale, and a bidirectional screw, can fix and clamp the wooden board used for paper mounting at the top center of the placement plate according to the size of the wooden board. At the same time, after the paper is placed on the wooden board, it can position the paper around its perimeter, improve the level of the paper placement, and improve the coincidence between the center of the paper and the center of the wooden board, thereby improving the quality of subsequent paper mounting.

[0023] 2. Compared with the prior art, this easy-to-operate paper mounting and positioning mechanism, by rotating the threaded block, moves it into the threaded groove. With the cooperation of the guide groove and the guide block, the placement plate moves the wooden board into the groove synchronously, making the surface of the wooden board flush with the top of the base. This facilitates the positioning of the paper placed on the wooden board after wooden boards of different thicknesses are clamped, thereby improving the practicality of the device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-5 This utility model provides an easy-to-operate paper mounting positioning mechanism, comprising a base 1, a slot 2 on the top of the base 1, a converging plate 18 fixedly connected to the bottom of the inner wall of the slot 2, a drain pipe 19 on the back of the base 1, a placement plate 3 inside the slot 2, two adjusting components at the bottom of the placement plate 3, two sets of clamping plates 4 on the placement plate 3, each set containing two clamping plates 4, two sliding grooves 5 on the top of the base 1, two positioning plates 6 slidably connected inside the two sliding grooves 5, a magnet 8 fixedly embedded inside one of the positioning plates 6, two limiting plates 9 magnetically connected to one side of one of the positioning plates 6, and a positioning... The scale 12, two positioning plates 6 are each movably inserted with a pin 10 on one side opposite to each other. The pin 10 is adapted to the insertion hole 11. Several insertion holes 11 are opened inside one of the sliding grooves 5. The base 1 is equipped with a lifting component for adjusting the height of the placement plate 3. Through the arrangement of the base 1, placement plate 3, clamping plate 4, positioning plate 6, limiting plate 9, positioning scale 12 and bidirectional screw 15, the wooden board used for paper mounting can be fixed and clamped at the top center of the placement plate 3 according to the size of the wooden board. At the same time, after the paper is placed on the wooden board, the paper can be positioned around its perimeter, improving the level of the paper placement and the coincidence of the center of the paper with the center of the wooden board, thereby improving the quality of subsequent paper mounting.

[0033] A connecting frame 13 is fixedly connected to the bottom of the placement plate 3. Four clearance slots 14 are provided on the placement plate 3. Four clamping plates 4 are slidably connected inside the four clearance slots 14. The adjustment component includes a bidirectional screw 15 rotatably connected inside the connecting frame 13. Two push rods 16 are threadedly connected to the outer surface of the bidirectional screw 15. The two push rods 16 are fixedly connected to the two clamping plates 4 respectively. Four guide rods 17 are fixedly connected to the connecting frame 13. The four guide rods 17 are movably connected to the two push rods 16 respectively. By adjusting the component, after the wooden board is placed on the placement plate 3, it can be clamped on both sides and front and back, improving its stability and positioning it in the center of the placement plate 3, which is convenient for subsequent paper positioning.

[0034] Guide grooves 20 are provided on both the front and back sides of the inner wall of the slot 2. Guide blocks 21 are slidably connected inside the two guide grooves 20. The two guide blocks 21 are fixedly connected to the bottom of the placement plate 3. The guide grooves 20 and guide blocks 21 can guide and limit the placement plate 3, improving its stability when moving up and down.

[0035] The lifting assembly includes a threaded groove 22 on the top of the base 1. A threaded block 23 is threadedly connected inside the threaded groove 22. A connecting plate 7 is rotatably connected to the top of the threaded block 23. The connecting plate 7 is fixedly connected to the top of the placement plate 3. By rotating the threaded block 23, it moves into the threaded groove 22. With the cooperation of the guide groove 20 and the guide block 21, the placement plate 3 moves the wooden board into the groove 2 synchronously, making the surface of the wooden board flush with the top of the base 1. This facilitates the positioning of paper placed on the wooden board after wooden boards of different thicknesses are clamped, thereby improving the practicality of the device.

[0036] Working principle: When in use, manually rotate one of the bidirectional screws 15. Under the guidance and limit of the corresponding guide rod 17, the corresponding two push rods 16 will drive the corresponding clamping plates 4 to move apart, which can increase the distance between the two clamping plates 4. Similarly, the position of the other two clamping plates 4 can be adjusted. Then, place the wooden board to be mounted on the top of the placement plate 3. Then rotate the bidirectional screw 15 again to move the four clamping plates 4 towards the center of the placement plate 3, which can clamp the wooden board in the center and maintain its stability. Then, the height of the placement plate 3 and the wooden board can be adjusted according to the thickness of the wooden board. That is, manually rotate the threaded block 23 to move it into the threaded groove 22. With the cooperation of the connecting plate 7, the guide groove 20 and the guide block 21, the placement plate 3 and the fixed wooden board will move down synchronously until the top of the wooden board is flush with the top of the base 1.

[0037] After adjusting the height of the wooden board, place the paper approximately at the center of the top of the board. Then, manually move the two positioning plates 6 relative to each other, allowing them to slide a certain distance within the two grooves 5 and initially contact the sides of the paper. This positions the paper from both sides, preventing it from tilting. Inserting the pins 10 into the corresponding holes 11 maintains the stability of the positioning plates 6. Then, according to the positioning scale 12, move the two limiting plates 9 relative to each other by an appropriate length to position the paper front and back. This improves the accuracy of the paper's center positioning relative to the center of the wooden board, thus improving the quality of subsequent paper mounting.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
