Description

Technical Field

[0001] The utility model belongs to the technical field of food printing equipment, and in particular relates to a fixing component of a guide shaft of a drawing machine. Background Art

[0002] Existing food printers, such as coffee latte machines and milk tea printers, almost all follow the structural features of 3D printers and use multiple transmission structures. For example, the ink cartridge is driven by a synchronous belt to move in the plane X and Y two-dimensional directions for printing, and the tray and substrate are driven by a lead screw to move in the Z vertical direction. In order to improve the structural stability of the entire latte machine and prevent the ink cartridge and tray from deflecting during movement, guide shafts are installed at corresponding positions to allow the ink cartridge and tray to slide along the corresponding guide shafts respectively.

[0003] In the art drawing machine product previously designed by the applicant, a connecting plate is fixed to the end of the guide shaft, and a mounting hole and three threaded positioning holes are formed on the connecting plate. The connecting plate is fixedly mounted on the end of the guide shaft through the mounting hole, and then three bolts are screwed into the corresponding threaded positioning holes to fix the connecting plate and the bracket, and the end face of the guide shaft is in contact with the surface of the bracket. This connection method is very strong, but it is inconvenient to disassemble and assemble, because not only three bolts are required for fixing, but the end faces at both ends of the guide shaft are in contact with the surface of the bracket, that is, the distance between the guide shaft and the bracket is the same, which makes it difficult to put the guide shaft into or take it out of the space of the bracket. Utility Model Content

[0004] The utility model aims to provide a fixing assembly for a guide shaft of a drawing machine, so as to solve the technical problem of inconvenient guide shaft assembly operation in the prior art.

[0005] In order to solve the above technical problems, the utility model adopts the following solutions:

[0006] The fixing assembly of the guide shaft of the drawing machine includes a fastener sleeved on the end of the guide shaft and a bracket detachably connected to the fastener; an assembly hole is opened on the bracket, and the fastener is a non-rotating body as a whole; when disassembling and assembling the guide shaft, the fastener is rotated by a certain angle, so that the fastener and the guide shaft can pass through the assembly hole; after assembly, the fastener cannot pass through the assembly hole.

[0007] By sleeve-mounting a fastener on the end of the guide shaft and opening an assembly hole on the bracket, when installing the guide shaft, rotate the fastener so that the fastener and the guide shaft pass through the assembly hole from the outside into the installation space in the bracket, and then rotate a certain angle to ensure that the fastener cannot pass through the assembly hole at this time, that is, it plays a limiting role to prevent the guide shaft from passing through the assembly hole, and then connect the bracket with the fastener, which is very convenient. When dismantling, loosen the connector, rotate the fastener, and make the fastener and the guide shaft pass through the assembly hole again, which is not affected by the narrow installation position in the bracket space, and the operation is very convenient.

[0008] Further optimization, the fastener is formed by processing a flat plate to form a mounting portion and a limiting portion; wherein, one side surface of the flat plate protrudes outward and extends to form a rotating body boss, a blind hole is opened along the height direction of the boss from the side surface of the flat plate away from the boss to form a mounting portion, and the parts of the flat plate located on both sides of the boss constitute the limiting portion; the end of the guide shaft is inserted into the blind hole, the boss extends out of the assembly hole and is located on the outside of the bracket, and the limiting portion is located on the inside of the bracket and connected to the bracket.

[0009] The length of the guide shaft is slightly longer than the length of the installation space between the brackets, and the boss is located on the outside of the bracket, so that the fastener can be rotated from the outside during disassembly and assembly, which is very convenient to operate.

[0010] Further optimization is performed in that the edge of the blind hole is chamfered to facilitate the insertion of the guide shaft into the blind hole.

[0011] Further optimization is that the limiting portion is provided with a first positioning hole, the bracket is provided with a second positioning hole, and the fastener is fixedly connected to the bracket by bolts screwed into the first positioning hole and the second positioning hole.

[0012] Because the guide shaft is not subjected to torque during operation, only one bolt is needed to fasten the fastener to the bracket, which is easy to operate and saves costs.

[0013] Further optimization, the flat plate as a whole is a non-circular plate, the outer edge shape of the flat plate is the same as the contour of the assembly hole, and the corresponding dimensions are also the same; when the guide shaft needs to be disassembled or installed, the bolt is removed and the fastener is rotated, so that the fastener can just pass through the assembly hole; when assembled, the first positioning hole and the second positioning hole correspond to each other, and at this time the limiting portion of the fastener cannot pass through the assembly hole.

[0014] Further optimization, the fastener is made of hard rubber, and the end of the guide shaft is interference fit with the fastener. Because hard rubber not only has a certain elasticity, it is easy to assemble and disassemble with the guide shaft by interference fit, but also has a certain strength, which is conducive to being fixed with the bracket by bolts.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] By sleeve-mounting a fastener on the end of the guide shaft and opening an assembly hole on the bracket, when the guide shaft needs to be installed, the fastener is rotated so that the fastener and the guide shaft pass through the assembly hole from the outside and enter the installation space in the bracket, and then rotated at a certain angle to ensure that the fastener cannot pass through the assembly hole at this time, that is, it plays a limiting role to prevent the guide shaft from passing through the assembly hole, and then the bracket is connected to the fastener, which is very convenient. When dismantling, loosen the connector, rotate the fastener, and make the fastener and the guide shaft pass through the assembly hole again, which is not affected by the narrow installation position in the bracket space, and the operation is very convenient.
