[0039] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. In the description of this invention, it should be noted that the terms "left," "right," "front," "rear," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0040] The following is in conjunction with the appendix Figures 1-3 The present invention will be further described in terms of its embodiments and implementation methods:

[0041] Figure 1 A schematic diagram of the three-dimensional structure of the feeding mechanism of a food 3D printer. Figure 1 ; Figure 2 A schematic diagram of the three-dimensional structure of the feeding mechanism of a food 3D printer. Figure 2 ; Figure 3 This is a side view of a feeding mechanism for a food 3D printer. The feeding mechanism includes a support part 4 and a conveying part 1. The conveying part 1 is used to convey materials. The support part 4 is connected to the conveying part 1 through a connecting part 2 and provides support for the conveying part 1. The driving component 102 of the conveying part 1 can drive the rotation of the conveying wheels 101, so that each pair of conveying wheels 101 rotates. The material is clamped by the conveying wheels 101 and driven to move under the friction of rotation.

[0042] In some embodiments, the conveyor wheels 101 are arranged in a straight line. For example, the conveyor wheels 101 may be arranged uniformly in a straight line, or they may be arranged non-uniformly in a straight line.

[0043] The conveyor wheel 101 can clamp and support the material.

[0044] It also includes a drive assembly 102 for driving the transmission wheel 101 to rotate. The drive assembly 102 is connected to the support rod, and the central axis of the drive assembly 102 is connected to the transmission wheel 101.

[0045] In some embodiments, the drive assembly 102 can be fixedly connected to the support rod by welding or bolting. The drive assembly 102 is a component that can provide rotational force, such as a motor or a servo motor.

[0046] In practical use, the material is held in the middle by the conveyor wheel 101, with both sides of the material adhering to the symmetrical sidewalls of the conveyor wheel 101. The drive assembly 102 drives the conveyor wheel 101 to rotate, and the material can be moved by friction and the transmission force during the rotation of the conveyor wheel 101. It should be noted that the two conveyor wheels 101 in each pair rotate in opposite directions to ensure that the side in contact with the material provides a symmetrical forward driving force to the material, thereby realizing the movement of the material. Since the width of the material is different, the distance between the conveyor wheels needs to be adjusted.

[0047] In some embodiments, in order to clamp and transport materials of different widths, a sliding component is provided. The sliding component enables the conveyor wheel 101 to slide along the support part 4, thereby adjusting the distance between the conveyor wheels 101 to accommodate materials of different widths.

[0048] Specifically, the connecting part 2 includes:

[0049] A sliding component is provided for sliding the conveying part 1 along the support part 4 in a first direction, the first direction being perpendicular to the direction in which the conveying wheel array is arranged;

[0050] The sliding component includes a sliding groove 6, which is slidably disposed on the support part 4. The support part 4 is U-shaped, and the sliding groove 6 is respectively matched with the two side rods of the support part 4.

[0051] It also includes: a limiting component 601, used to limit the sliding groove 6, the limiting component 601 being a set screw, the set screw being screwed to one side of the sliding groove 6, the set screw being able to abut against the support part 4.

[0052] By setting a sliding slot 6, which is slidably mounted on the support part 4, the sliding slot 6 can slide along the support part 4, thereby driving the support rod and the transmission wheel 101 to move and adjusting the distance between the transmission wheels 101.

[0053] In actual use, after the sliding slot 6 of the sliding component moves the support rod and the transmission wheel 101 to adjust the distance between the transmission wheel 101, the sliding slot 6 can be limited by the limiting component 601 to ensure that the positions of the two transmission wheels 101 no longer change.

[0054] In some embodiments, in order to facilitate the transfer of materials between the conveyor wheels 101 and to adapt to materials within a certain width range, an elastic component 3 is provided. By providing the elastic component 3 on the connecting part 2 and connecting it to the conveying part 1, the conveying part 1 can adapt to materials within a certain width range, realize the clamping and conveying of materials of different widths within a certain range, and, due to the provision of the elastic component 3, materials can be easily inserted between the symmetrical conveyor wheels 101 to realize the feeding and transmission of materials.

[0055] Specifically, the elastic component 3 is used to clamp and provide elastic buffering when the conveyor wheel 101 clamps the material, ensuring that the symmetrical conveyor wheel 101 can clamp the material.

[0056] The elastic component 3 is connected to the connecting support rod, the support rod is a square rod, one end of the support rod is fixedly connected to the elastic component 3, and the elastic component 3 is connected to the connecting part 2;

[0057] The elastic component 3 includes:

[0058] The connecting plate 301 is used to connect the sliding slot 6 of the sliding assembly, and one side of it is connected to one end of the spring 302 and is passed through by the connecting part 2;

[0059] The limiting plate 303 is used to connect the connecting part 2. One side of the limiting plate 303 is connected to the other end of the spring 302 and is fixedly connected to the outer end of the connecting part 2. The spring 302 is disposed between the connecting plate 301 and the limiting plate 303.

[0060] In practical use, when material is inserted, the conveyor wheel 101 moves to both sides due to the pushing force of the material, which in turn drives the support rod to move. The support rod drives the limiting plate 303 to move, and the limiting plates 303 on both sides move away from each other. The spring 302 is stretched. When the material is inserted between the conveyor wheels 101, due to the rebound force of the spring 302, the limiting plate 303 is pulled to move in the return direction, which drives the support rod and the conveyor wheel 101 to move closer to each other, thus realizing the function of the conveyor wheel 101 tightly clamping the material.

[0061] In some embodiments, a base 5 is further included for connecting the support portion 4 and providing support for the support portion 4. The base 5 is provided with a plurality of mounting holes 501. By providing the base 5 to support the support portion 4, the mounting holes 501 facilitate the installation and fixing of the base 5.

[0062] After the limiting component 601 limits the sliding slot 6, manually adjusting the position of the sliding slots 6 on both sides may cause the conveyor wheel 101 to become loose, resulting in the material not being directly in front of the feed inlet when the conveyor wheel 101 conveys the material, leading to feeding failure or low feeding efficiency. If the sliding slots 6 on both sides can be adjusted simultaneously during adjustment to achieve synchronous adjustment of the sliding slots 6 on both sides, the purpose of ensuring that the material is directly in front of the feed inlet can be achieved during feeding.

[0063] In some embodiments, a rotating component 7 may be included for driving the sliding component to move along a first direction, the rotating component 7 comprising:

[0064] The connecting rod 701 has one end rotatably connected to the lower side of the slide groove slot, and the other end rotatably connected to the lower edge of the turntable 703.

[0065] A handle 702 is used to rotate the turntable 703. The rotation of the handle 702 is connected to the support part 4. The axis of the handle 702 is adapted to coincide with the axis of symmetry of each pair of transmission wheels 101. The lower end of the handle 702 is fixedly connected to the center of the turntable 703.

[0066] Since the turntable 703 and the connecting rod 701 are rotatably connected, and the connecting rod 701 is rotatably connected to the sliding slot 6, when the turntable 703 rotates, the connecting rod 701 can drive the sliding slot 6 to move along the support part 4, so as to realize the synchronous movement of the two sliding slots 6.

[0067] In actual use, after the limiting component 601 releases the limiting of the sliding slot 6, the turntable 703 is rotated by rotating the handle 702. The turntable 703 drives the connecting rod 701 to swing. The two connecting rods 701 drive the two sliding slots 6 to move respectively, so as to realize the synchronous movement of the sliding slots 6. The sliding slots 6 can drive the movement of the transmission wheel 101, so as to realize the synchronous opposite or opposite displacement of the two transmission wheels 101 based on the axis of symmetry as the center line.

[0068] In some embodiments, the conveyor wheel 101 includes two identical and fixedly connected frustums, with the smaller end of the frustum fixed together.

[0069] This method increases the contact area with the material and better limits the material's movement within the grooves in the middle of the conveyor wheel.

[0070] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
