Description

Technical Field

[0001] This utility model belongs to the field of printing technology, and in particular relates to a positioning component for a printing roller. Background Technology

[0002] Rubbing is the reproduction of patterns and text carved or engraved in stone. The method involves tightly covering the artwork with a sheet of paper and then rubbing it with black or colored material. Traditional rubbing materials include Xuan paper and a block of black material called rubbing wax. The existing technology has the following problems: A rubbing machine is a device for rubbing patterns or text. During use, rubbing paper, a carving board, and rubbing wax paper need to be placed sequentially on top of the machine. Then, a printing roller transfers the pattern or text from the carving board to the rubbing paper. The printing roller needs to be placed on top of the machine and positioned with bolts. These bolts are prone to loosening over time, leading to unstable rotation of the printing roller and affecting the printing effect. Furthermore, bolt connections are time-consuming and inconvenient. However, existing rubbing machines lack a convenient and stable component for positioning the printing roller. Therefore, a positioning component for the printing roller is proposed to solve these problems. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a positioning component for a printing roller, which has the advantages of convenient and stable positioning of the printing roller. It solves the problem that existing printing machines are devices for printing patterns or text. During use, printing paper, a printing plate, and printing wax paper need to be placed on the top of the printing machine in sequence. Then, the pattern or text on the printing plate is transferred to the printing paper by the printing roller. During installation, the printing roller needs to be placed on the top of the printing machine and positioned by bolts. The bolts are prone to loosening after long-term use, resulting in unstable rotation of the printing roller and affecting the printing effect. Moreover, the bolt connection is time-consuming and inconvenient. However, existing printing machines do not have a convenient and stable component for positioning the printing roller.

[0004] This utility model is implemented as follows: a positioning assembly for a printing roller includes a printing machine and two support shells. The bottom of the support shell is fixedly connected to the top of the printing machine. A fixing clip is movably connected to the inner cavity of the support shell. The surface of the fixing clip contacts the inner cavity of the support shell. A printing roller is movably connected to one side of the two fixing clips via a rotating shaft. A device groove is provided on the top of the fixing clip. A device shell is movably connected to the inner cavity of the device groove. Insertion grooves are provided on both the front and rear sides of the top of the support shell. A control block is movably connected to the inner cavity of the device shell. The side of the control block near the printing machine penetrates the device shell and extends to the outside of the inner cavity of the device shell. A limit device is provided in the inner cavity of the device shell.

[0005] As a preferred embodiment of this utility model, the limiting device includes two limiting shells. The opposite sides of the two limiting shells penetrate the device shell and the fixing shell and extend to the outside of the fixing shell. A spring is fixedly connected to the opposite side of the two limiting shells. A stabilizing block that cooperates with the limiting shell is fixedly connected to the inner cavity of the device shell. The surface of the stabilizing block is in contact with the inner cavity of the limiting shell. By setting the limiting device, when the printing roller moves to the top of the printing machine, the limiting device has a limiting effect on the position of the printing roller.

[0006] In a preferred embodiment of this invention, a compression ring is fixedly connected to the side of the control block away from the printing machine. By setting the compression ring, the rotation of the control block drives the compression ring to rotate along the surface of the compression block. The compression force of the compression ring on the compression block can drive the two compression blocks to move.

[0007] As a preferred embodiment of this utility model, the top of the limiting shell is fixedly connected to a compression block that works in conjunction with a compression ring. The surface of the compression block is movably connected to the inner cavity of the compression ring. By setting the compression block, the two compression blocks will move closer to each other under the compression force of the compression ring. When the compression block moves, it can drive the two limiting shells to move.

[0008] As a preferred embodiment of this invention, a control ring is fixedly connected to the side of the control block closest to the printing machine. By setting the control ring, the user's operation is made more convenient, and the rotation of the control block is made more convenient.

[0009] As a preferred embodiment of this utility model, limiting grooves are provided on both the front and rear sides of the inner cavity of the support shell. The surface of the limiting shell contacts the inner cavity of the limiting groove. By providing the limiting groove, when the device shell moves into the inner cavity of the device groove, the control ring is released, and the restoring force generated by the spring returning to its shape drives the limiting shell to be locked into the inner cavity of the limiting groove. The cooperation between the limiting shell and the limiting groove has a limiting effect on the position of the device shell.

[0010] As a preferred embodiment of this utility model, the front and rear sides of the device housing are fixedly connected with plug-in blocks that cooperate with the plug-in slots. The surface of the plug-in block contacts the inner cavity of the plug-in slot. By setting the plug-in block, the cooperation between the plug-in block and the plug-in slot restricts the movement position of the device housing, so that the device housing can be accurately moved to the inner cavity of the device slot.

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

[0012] 1. This utility model solves the problem of existing printing machines, which are devices for printing patterns or text, by setting up a limiting device, a limiting shell, a spring, a stabilizing block, a squeezing ring, and a limiting groove in combination. These machines require the printing paper, a printing plate, and printing wax paper to be placed on top of the printing machine in sequence, and then the pattern or text on the printing plate is transferred to the printing paper by a printing roller. The printing roller needs to be placed on top of the printing machine and positioned by bolts. The bolts are prone to loosening after long-term use, which leads to unstable rotation of the printing roller and affects the printing effect. Moreover, the bolt connection is time-consuming and inconvenient. However, existing printing machines do not have a convenient and stable component for positioning the printing roller.

[0013] 2. By setting a limiting device, the extrusion blocks will move closer to each other under the extrusion pressure of the extrusion ring. When the extrusion blocks move, they can drive the two limiting shells to move closer to each other along the surface of the stabilizing block. The force generated when the limiting shells move causes the spring to undergo elastic deformation. The limiting device has a limiting effect on the position of the printing roller.

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4As shown in the figure, the positioning assembly for a printing roller provided in this embodiment of the utility model includes a printing machine 1 and two support shells 2. The bottom of the support shell 2 is fixedly connected to the top of the printing machine 1. A fixing shell 3 is movably connected to the inner cavity of the support shell 2. The surface of the fixing shell 3 contacts the inner cavity of the support shell 2. A printing roller 4 is movably connected to one side of the two fixing shells 3 via a rotating shaft. A device groove 5 is provided on the top of the fixing shell 3. A device shell 6 is movably connected to the inner cavity of the device groove 5. Insertion grooves 7 are provided on both the front and rear sides of the top of the support shell 2. A control block 8 is movably connected to the inner cavity of the device shell 6. The side of the control block 8 near the printing machine 1 passes through the device shell 6 and extends to the outside of the inner cavity of the device shell 6. A limit device 9 is provided in the inner cavity of the device shell 6.

[0022] refer to Figure 4 The limiting device 9 includes two limiting shells 901. The opposite sides of the two limiting shells 901 penetrate the device shell 6 and the fixing shell 3 and extend to the outside of the fixing shell 3. A spring 902 is fixedly connected to the opposite side of the two limiting shells 901. A stabilizing block 903 that cooperates with the limiting shell 901 is fixedly connected to the inner cavity of the device shell 6. The surface of the stabilizing block 903 is in contact with the inner cavity of the limiting shell 901.

[0023] The above solution is adopted: by setting a limiting device 9, when the printing roller 4 moves to the top of the printing machine 1, the limiting device 9 has a limiting effect on the position of the printing roller 4.

[0024] refer to Figure 4 A compression ring 10 is fixedly connected to the side of the control block 8 away from the printing machine 1.

[0025] The above scheme is adopted: by setting the extrusion ring 10, the control block 8 rotates and drives the extrusion ring 10 to rotate along the surface of the extrusion block 11. The extrusion force of the extrusion ring 10 on the extrusion block 11 can drive the two extrusion blocks 11 to move.

[0026] refer to Figure 4 The top of the limiting shell 901 is fixedly connected to a compression block 11 that works in conjunction with the compression ring 10, and the surface of the compression block 11 is movably connected to the inner cavity of the compression ring 10.

[0027] Using the above scheme: by setting up the compression block 11, the two compression blocks 11 will move closer to each other under the compression force of the compression ring 10. When the compression block 11 moves, it can drive the two limiting shells 901 to move.

[0028] refer to Figure 4 A control ring 12 is fixedly connected to the side of the control block 8 near the printing machine 1.

[0029] The above solution is adopted: by setting up control ring 12, control ring 12 increases the convenience of user operation and increases the convenience of rotating control block 8.

[0030] refer to Figure 3 Limiting grooves 13 are provided on both the front and rear sides of the inner cavity of the support shell 2, and the surface of the limiting shell 901 is in contact with the inner cavity of the limiting groove 13.

[0031] The above scheme is adopted: by setting the limiting groove 13, when the device shell 6 moves into the inner cavity of the device groove 5, the control ring 12 is released, and the restoring force generated by the spring 902 returning to its shape drives the limiting shell 901 to be inserted into the inner cavity of the limiting groove 13. The cooperation between the limiting shell 901 and the limiting groove 13 has a limiting effect on the position of the device shell 6.

[0032] refer to Figure 4 Both the front and rear sides of the device housing 6 are fixedly connected with plug blocks 14 that cooperate with the plug slot 7, and the surface of the plug block 14 is in contact with the inner cavity of the plug slot 7.

[0033] The above solution is adopted: by setting the plug-in block 14, the plug-in block 14 and the plug-in groove 7 work together to restrict the movement of the device shell 6, so that the device shell 6 can be accurately moved into the inner cavity of the device groove 5.

[0034] The working principle of this utility model:

[0035] In use, when it is necessary to conveniently and stably position the printing roller 4 on the printing machine 1, first place the fixing housing 3 in the inner cavity of the support housing 2. The movement of the fixing housing 3 drives the printing roller 4 to the top of the printing machine 1. Then, rotate the control ring 12. When the control ring 12 rotates, it drives the control block 8 to rotate. The rotation of the control block 8 drives the extrusion ring 10 to rotate along the surface of the extrusion block 11. The extrusion block 11 will move closer to each other due to the extrusion force of the extrusion ring 10. When the extrusion block 11 moves, it can drive the two limiting housings 901 to move closer to each other along the surface of the stabilizing block 903. The force generated when the shell 901 moves causes the spring 902 to undergo elastic deformation. When the limiting shell 901 moves completely into the inner cavity of the device shell 6, it moves the device shell 6 into the inner cavity of the device groove 5. When the device shell 6 moves, it drives the insertion block 14 to move into the inner cavity of the insertion groove 7. Then, the control ring 12 is released, and the restoring force generated by the spring 902 returning to its shape drives the limiting shell 901 to pass through the device shell 6 and the fixing clip 3 and move into the inner cavity of the limiting groove 13. The cooperation of the limiting shell 901 and the limiting groove 13 has a positioning function for the printing roller 4. At this time, the printing roller 4 is conveniently and stably positioned in the printing machine 1.

[0036] In summary, the positioning component of the printing roller 4, through the coordinated use of the limiting device 9, limiting shell 901, spring 902, stabilizing block 903, extrusion ring 10, and limiting groove 13, solves the problem that existing printing machines are devices for printing patterns or text. In these machines, the printing paper, stencil, and wax paper need to be placed sequentially on top of the machine before the printing roller transfers the pattern or text from the stencil to the printing paper. The printing roller is also positioned using bolts after being placed on top of the machine. However, these bolts are prone to loosening over time, leading to unstable rotation of the printing roller and affecting the printing effect. Furthermore, bolt connections are time-consuming and inconvenient. Existing printing machines lack a convenient and stable component for positioning the printing roller.
