[0040] In this embodiment of the invention, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part of a structure. They can be mechanical or electrical connections. They can be direct connections or indirect connections through an intermediate medium, and can represent the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention based on the specific circumstances.

[0041] like Figures 1 to 5 As shown, this utility model embodiment provides a spoon feeding machine, including a feeding mechanism 100, a suction cup 200, a limiting member 300, a first mounting plate 400, a tension spring 500, a first transmission assembly 600, a cam 700, a motor 800, and a second transmission assembly 900.

[0042] The feeding mechanism 100 has an upward-facing discharge port 110, at which a spoon with its back facing upward and positioned along the X-axis is placed. The feeding mechanism 100 is existing technology and will not be described in detail here. Furthermore, the spoon has a spoon portion and a handle portion. A suction cup 200 and a limiting member 300 are spaced apart above the discharge port 110 along the X-axis. The suction cup 200 corresponds to the spoon portion, and the limiting member 300 corresponds to the handle portion. The suction cup 200 and the limiting member 300 are connected by a connecting plate 430. The suction cup 200 can move along the Y-axis. When the suction cup 200 moves downward along the Y-axis and adheres to the spoon portion, the lower end of the limiting member 300 abuts against the handle portion. The design utilizes a suction cup 200 to hold the spoon in place and a limiting member 300 to hold the handle, creating a two-point positioning system. This ensures the spoon remains stable when held in place, preventing it from wobbling and potentially falling off or misaligning the feeding position. This effectively improves work efficiency. The connection between the suction cup 200 and the limiting member 300 via a connecting plate 430 allows the limiting member 300 to move synchronously, reducing the need for independent drive components, lowering equipment complexity, and reducing costs.

[0043] In one embodiment, a first mounting plate 400 is disposed on one side of the feeding mechanism 100, and a first slider 410 disposed on it along the Y-axis direction. A first guide rail 420 that can slide along the Y-axis direction is disposed on the first slider 410. A connecting plate 430 is fixed to the lower end of the first guide rail 420. The first slider 410 and the first guide rail 420 play a guiding role, improving the accuracy of the vertical movement of the suction cup 200 and the limiting member 300. Furthermore, the upper end of the tension spring 500 is connected to the first guide rail 420 and the lower end is connected to the first mounting plate 400, which is used to drive the first guide rail 420 to move downward along the Y-axis direction, eliminating the need for an additional power source and reducing costs. The tension spring 500 flexibly presses down to avoid hard impacts that could damage the spoon.

[0044] In one embodiment, such as Figure 2 and 3 As shown, the first transmission assembly 600 includes a brake cable 610, a swing rod 620, and a fixed shaft 630. The fixed shaft 630 is arranged along the X-axis and is rotatably connected to the swing rod 620. One end of the brake cable 610 is connected to the first guide rail 420, and the other end is connected to one end of the swing rod 620. The swing rod 620 can swing around the fixed shaft 630. When the end of the swing rod 620 connected to the brake cable 610 swings downward, it can pull the brake cable 610 to drive the first guide rail 420 to move upward along the Y-axis. That is, the upward movement of the suction cup 200 is controlled by the cooperation of the swing rod 620 and the brake cable 610. The structure is simple and stable.

[0045] Specifically, a flexible protective tube 611 is fitted onto the brake line 610. One end of the flexible protective tube 611 abuts against the upper end of the first mounting plate 400. A support plate 612 for limiting the swing arm is also provided above the swing arm 620. The other end of the flexible protective tube 611 abuts against the support plate 612. The flexible protective tube 611 allows the brake line 610 to bend upward, providing support and guidance, and making the space more concise. Furthermore, both ends of the brake line 610 pass through the first mounting plate 400 and the support plate 612 respectively, and are fixedly connected to the swing arm 620 and the first guide rail 420.

[0046] In one embodiment, such as Figure 3 and 4As shown, in order to enable the swing arm 620 to swing around the fixed shaft 630, a cam 700 is also installed, wherein the axial direction of the cam 700 is parallel to the axial direction of the fixed shaft 630, and a roller 621 is provided at the other end of the swing arm 620. The roller 621 abuts against the outer wall of the cam 700, and the cam 700 can rotate around its axial direction to drive the swing arm 620 to swing around the fixed shaft 630. It should be noted that the tension spring 500 utilizes its elasticity and, through the brake cable 610, enables the swing rod 620 to be subjected to an upward pulling force, so that the roller 621 can always abut against the outer wall of the cam 700. Furthermore, the cam 700 is a two-wing rotating cam. Specifically, the outer wall of the cam 700 includes two first arc segments and two second arc segments. The two first arc segments are symmetrically arranged about the axis of the cam 700. The second arc segments are bent inward, and their two ends are respectively connected to the opposite ends of the two first arc segments. The first arc segments can push the roller 621 to cause the end connected to the roller 621 to swing upward, so that the end of the swing rod 620 connected to the brake cable 610 swings downward.

[0047] Furthermore, such as Figure 3 As shown, the second transmission assembly 900 includes a turntable 910, a connecting rod 920, a second mounting plate 930, a second guide rail 940, and a second slider 950. The cam 700 is coaxially fixed to the output shaft of the motor 800 with the turntable 910. An eccentric shaft 911 is provided on the turntable 910. Furthermore, the second mounting plate 930 is located on the side of the first mounting plate 400 away from the first slider 410. The second guide rail 940 is provided along the Z-axis on the side of the second mounting plate 930 away from the first mounting plate 400. The second slider 950 is slidably mounted on the second guide rail 940. A fixing plate 951 is provided on the second slider 950. Both ends of the connecting rod 920 are rotatably connected to the eccentric shaft 911 and the fixing plate 951, respectively. The first mounting plate 400 and the fixing plate 951 are connected via an adjustment assembly 960. When the motor 800 drives the cam 700 and the turntable 910 to rotate, the cam 700 will drive the swing rod 620 to swing around the fixed shaft 630. The turntable 910 drives the connecting rod 920 through the eccentric shaft 911 to drive the second slider 950 to move along the Z-axis, which in turn drives the suction cup 200 to move along the Z-axis.

[0048] With the cooperation of the first transmission component 600 and the second transmission component 900, the suction cup 200 will move along an upwardly arched arc path. The two ends of the arc path correspond to the discharge port 110 and the conveyor belt installed on one side of the feeder, respectively. Specifically, the suction cup 200 first moves downward along the Y-axis to adsorb the spoon. Then, while moving upward along the Y-axis to disengage the spoon from the discharge port 110, the suction cup 200 also moves along the Z-axis in a direction away from the feeding mechanism 100. When it reaches the highest point, the end of the swing rod 620 connected to the brake line 610 swings upward, and the tension spring 500 drives the first guide rail 420 downward to move the suction cup 200 downward, placing the spoon on the conveyor belt.

[0049] In one embodiment, such as Figure 3 and 5 As shown, the adjustment assembly 960 includes a first adjusting member 961 and a first locking member 962. The first adjusting member 961 is vertically disposed at the upper end of the first mounting plate 400, and its lower end passes through the first mounting plate 400 and is fixedly connected to the fixing plate 951. The first locking member 962 is threadedly connected to the first adjusting member 961 and abuts against the upper end of the first mounting plate 400. Specifically, the first adjusting member 961 is a screw and the first locking member 962 is a nut. By rotating the first locking member 962, the first mounting plate 400 can be driven up or down, thereby driving the suction cup 200 and the limiting member 300 to move up or down, thus finely adjusting the distance between the suction cup 200 and the limiting member 300 and the spoon. The operation is simple and convenient, and can improve the accuracy of adjustment.

[0050] In one embodiment, such as Figure 3 and 5 As shown, the adjustment assembly 960 also includes a second adjustment member 963. The fixing plate 951 has a vertically arranged first strip hole 952. Specifically, two first strip holes 952 are spaced apart along the Z-axis. Further, the first mounting plate 400 has a connecting hole 440 corresponding to the first strip hole 952. The second adjustment member 963 passes through the first strip hole 952 and is threadedly connected to the connecting hole 440. Specifically, two first strip holes 952 are spaced apart along the Z-axis. The second adjustment member 963 is preferably a screw. That is, the distance between the suction cup 200 and the limiting member 300 and the spoon can be significantly adjusted through the cooperation of the second adjustment member 963 and the first strip hole 952. Operators can choose the adjustment method according to their needs, further improving the convenience of operation and work efficiency.

[0051] In one embodiment, such as Figure 3 and 5As shown, the connecting plate 430 is provided with a second strip hole 431 arranged along the X-axis direction. The limiting member 300 includes a rod 310, a baffle 320 and a third locking member 330. The baffle 320 is horizontally arranged at the lower end of the rod 310 and can abut against the handle of the spoon. The front side of the baffle 320 is also provided with a downwardly extending extension wall 321, which abuts against the side of the handle of the spoon, thereby limiting the handle and preventing it from shaking.

[0052] The rod 310 passes through the second slot 431. Two third locking members 330 are threadedly connected to the rod 310, spaced apart. One third locking member 330 abuts against the upper end of the connecting plate 430, and the other abuts against the lower end of the connecting plate 430. Both the second locking member 240 and the third locking member 330 are preferably nuts. The suction cup 200 can be locked or released by the engagement of one third locking member 330 with the head 230, and the limiting member 300 can be locked or released by the engagement of two third locking members 330. This simple operation facilitates disassembly, assembly, maintenance, and replacement. The second slot 431 allows the distance between the suction cup 200 and the limiting member 300 to be adjusted along the X-axis to accommodate spoons of different sizes, improving work efficiency.

[0053] Furthermore, the suction cup 200 includes a suction nozzle 210 and a vertically arranged tube 220. The suction nozzle 210 is located at the lower end of the tube 220 and communicates with the tube 220. The tube 220 is arranged through the second strip hole 431, and a head 230 is provided at the upper end of the tube 220. Specifically, the head 230 is connected to the air tube, and the suction nozzle 210 can be able to suck up or release the spoon by sucking up and releasing air.

[0054] Furthermore, the head 230 abuts against the upper end of the connecting plate 430, and the tube body 220 is also provided with a second locking member 240 that is threadedly connected to it. The second locking member 240 abuts against the lower end of the connecting plate 430.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
