Description

Technical Field

[0001] This utility model belongs to the field of 3D food printing technology, specifically relating to a single-drive three-way positioning mechanism. Background Technology

[0002] In the field of 3D food printing, accurate positioning of the printed object is a key factor in ensuring printing quality and precision. As a carrier for food raw materials or semi-finished products, the accurate positioning of the tray during the printing process is crucial. Currently, existing positioning mechanisms use multiple independent drive sources to perform positioning operations in different directions. This not only makes the entire positioning system complex and bulky, but also significantly increases equipment costs. Furthermore, the coordinated control between multiple drive sources is difficult, and the problem of accumulated positioning errors is prone to occur, making it difficult to meet the high-precision positioning requirements of 3D food printing. In addition, some positioning mechanisms are not perfect in their positioning methods, only able to achieve positioning in a single direction or a limited number of directions. During the 3D food printing process, if the tray shifts or shakes in any direction, it may cause the printed food to deviate from the design model in terms of shape, size, and details, seriously affecting the printing effect and food quality. Therefore, there is an urgent need for a single-drive three-direction positioning mechanism to solve the above problems. Utility Model Content

[0003] In view of the problems mentioned above in the background technology, the purpose of this utility model is to provide a single-drive three-way positioning mechanism.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A single-drive three-way positioning mechanism includes a mounting plate and a tray. A cylinder is mounted on the top of the mounting plate, and a mounting seat is mounted on the power output end of the cylinder. A small push rod is threaded onto the other side of the mounting seat, and a connecting seat is slidably mounted on the other side of the small push rod. A spring is sleeved on the outer surface of the small push rod. One side of the spring is mounted on the mounting seat, and the other side of the spring is mounted on the connecting seat. First connecting posts are mounted on both sides of the top of the connecting seat, and connecting strips are mounted on the top of the first connecting posts on both sides. Second connecting posts are mounted on the other side of the connecting strips. The second connecting posts are connected to a transverse sliding seat. A clamping seat is mounted on the outer side of the transverse sliding seat. A positioning protrusion is provided on the upper side of the clamping surface of the clamping seat, and a positioning groove is provided on the lower side of the clamping surface of the clamping seat. Matching anti-disengagement slots are provided on both sides of the tray at the corresponding positioning protrusions and positioning grooves.

[0006] Furthermore, both the mounting base and the connecting base are equipped with a first linear slider at their bottoms. The first linear slider is slidably connected to a first linear slide rail, which is vertically mounted on the mounting plate. The bottoms of the two transverse sliding bases on both sides are equipped with second linear sliders, which are slidably connected to second linear slide rails, which are horizontally mounted on the mounting plate. This structural design provides guiding movement and ensures smooth and stable movement.

[0007] Furthermore, a bracket is mounted on one side of the top of the mounting plate, and one side of the cylinder is fixedly mounted on the bracket. This structural design facilitates the fixed installation of the cylinder.

[0008] Furthermore, both the first and second connecting columns are equipped with rotating bearings on their lower sides, which are installed within the connecting seat and the transverse sliding seat. This structural design enables the first and second connecting columns to rotate, improving their performance.

[0009] Furthermore, the transverse sliding seat and the clamping seat are integrally formed. This structural design facilitates manufacturing and provides high connection strength.

[0010] The beneficial effects of this utility model are as follows: By using a single cylinder as the driving source, this utility model replaces the design of multiple independent driving sources in the traditional mechanism, fundamentally solving the problem of complex structure and large size of the original system. This simplification not only reduces the number of parts used and lowers the production and assembly costs of the equipment, but also saves installation space, making the entire positioning mechanism easier to integrate into the 3D food printing equipment and improving the overall compactness of the equipment. Through the precise cooperation between the positioning protrusions and positioning grooves of the clamping seat and the anti-detachment grooves of the tray, the displacement and shaking of the tray in the front-back, left-right, and up-down directions can be restricted simultaneously. This solves the defect of the traditional positioning mechanism that can only achieve positioning in a single or limited direction. This all-round positioning effect can effectively avoid deviations in the shape, size and details of the food caused by tray offset during the printing process, ensuring that the printed food is highly consistent with the design model, and significantly improving the printing effect and food quality.

Detailed Implementation

[0018] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Example 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a single-drive three-way positioning mechanism is provided. A cylinder 2 is mounted on the top of the mounting plate 1. A mounting base 3 is mounted on the power output end of the cylinder 2. A small push rod 4 is threaded onto the other side of the mounting base 3. A connecting base 5 is slidably mounted on the other side of the small push rod 4. A spring 6 is sleeved on the outer surface of the small push rod 4. One side of the spring 6 is mounted on the mounting base 3, and the other side of the spring 6 is mounted on the connecting base 5. First connecting posts 7 are mounted on both sides of the top of the connecting base 5. Connecting strips 8 are mounted on the top of the first connecting posts 7 on both sides. Second connecting posts 9 are mounted on the other side of the connecting strips 8. A transverse sliding base 10 is connected to the second connecting post 9. A clamping base 11 is mounted on the outer side of the transverse sliding base 10. A positioning protrusion 12 is provided on the upper side of the clamping surface of the clamping base 11, and a positioning groove 13 is provided on the lower side of the clamping surface of the clamping base 11. Matching anti-detachment slots 14 are provided on both sides of the tray 100 at the corresponding positioning protrusions 12 and positioning grooves 13.

[0020] In this embodiment, when the tray 100 needs to be positioned, the cylinder 2 is activated, pushing the mounting base 3 forward. The mounting base 3 drives the small push rod 4 and the spring 6 to move forward. The spring 6 pushes the connecting base 5, which in turn drives the first connecting post 7. The first connecting post 7 drives the connecting strip 8, which drives the second connecting post 9. The second connecting post 9 drives the transverse sliding base 10, which in turn drives the clamping base 11 to move towards the center. The clamping base 11 drives the positioning protrusion 12 and the positioning groove 13 to gradually approach and grip the anti-detachment groove 14 of the tray 100. The clamping base 11, the positioning protrusion 12, and the positioning groove 13 limit the position of the tray 100, preventing it from shaking back and forth, left and right, up and down, and ensuring that the tray 100 can be stably clamped. This allows the 3D food printer to accurately print the food at the predetermined position on the tray, completing a high-quality 3D food printing task.

[0021] Example 2, as Figure 1 , Figure 2 and Figure 3 As shown, this embodiment adds the following structure based on embodiment 1: a first linear slider 15 is installed at the bottom of both the mounting base 3 and the connecting base 5. The first linear slider 15 is slidably connected to a first linear slide rail 16. The first linear slide rail 16 is vertically installed on the mounting plate 1. A second linear slider 17 is installed at the bottom of the two transverse sliding bases 10. The second linear slider 17 is slidably connected to a second linear slide rail 18. The second linear slide rail 18 is horizontally installed on the mounting plate 1.

[0022] In this embodiment, during use, when the mounting base 3 and the connecting base 5 move, the first linear slider 15 slides along the first linear slide rail 16, thereby ensuring that the mounting base 3 and the connecting base 5 can perform smooth linear movement. Similarly, when the two transverse sliding bases 10 move, the second linear slider 17 slides along the second linear slide rail 18, thereby ensuring that the transverse sliding base 10 can perform smooth linear movement, thus improving the subsequent clamping and fixing effect.

[0023] Example 3, as Figure 1 and Figure 2 As shown, this embodiment adds the following structure to the embodiment 1: a bracket 19 is installed on one side of the top of the mounting plate 1, and one side of the cylinder 2 is fixedly installed on the bracket 19.

[0024] In this embodiment, during installation, one side of the cylinder 2 is locked and fixed on the bracket 19, and the power output end of the cylinder 2 is installed on the mounting base 3. This fixes the cylinder 2 in place without affecting its normal use.

[0025] Example 4, as Figure 3As shown, this embodiment adds the following structure to the embodiment 1: a rotating bearing 20 is installed on the lower side of both the first connecting column 7 and the second connecting column 9, and the rotating bearing 20 is installed in the connecting seat 5 and the transverse moving seat 10.

[0026] In this embodiment, when the connecting seat 5 drives the first connecting column 7, the first connecting column 7 drives the connecting bar 8, the connecting bar 8 drives the second connecting column 9, and the second connecting column 9 drives the transverse seat 10 to move, since the first connecting column 7 and the second connecting column 9 are both equipped with rotating bearings 20 on their lower sides, the first connecting column 7 and the second connecting column 9 can rotate during movement, making the transmission smoother.

[0027] Example 5, as Figure 1 As shown, this embodiment adds the following structure to the embodiment 1: the transverse sliding seat 10 and the clamping seat 11 are integrally formed.

[0028] In this embodiment, during production, there is no need to separately process the transverse sliding seat 10 and the clamping seat 11 before assembly, which reduces the processing steps and assembly links of the parts. This not only reduces the operational complexity of the production process, but also effectively shortens the production cycle and improves the overall production efficiency. Furthermore, the one-piece molding design eliminates the connection gaps and assembly interfaces between the transverse sliding seat 10 and the clamping seat 11, thereby significantly improving the connection strength and overall structural rigidity between the two, avoiding problems such as loose connections and breakage, and extending the service life of the product.

[0029] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
