The movement of the inner rod of the electric push rod causes the connecting frame 8 and the enclosure 3 to rise and fall. When the robotic arm inside the vending machine places the goods 0 on the finished product placement seat 2, the electric push rod will push the enclosure 3 to rise and enclose the finished product placement seat 2 and the goods 0 above it. Only then will the safety door 5 open to allow the buyer to reach in and take the goods. The enclosure 3 also protects the hands, preventing the machine inside the vending machine from injuring the hands.

[0030] The frame body 1 is in the shape of "7", and the frame body 1 is provided with an embedded position 102 matching the shape of the enclosure 3 at the position of the enclosure 3. The inner side of the lower end of the enclosure 3 is provided with an inner edge strip 301 for limiting the upward disengagement of the enclosure 3 from the finished product placing seat 2. When the enclosure 3 rises to the highest position, the top end of the enclosure 3 is embedded into the embedded position 102, thereby tightly surrounding the finished product placing seat 2. At this time, the inner edge strip 301 is still located below the edge of the finished product placing seat 2, achieving the effect of position limitation.

[0031] The taking opening 101 is slidingly provided with a safety door 5 connected by a plurality of chain plates 501. In this embodiment, the safety door 5 is connected by a plurality of chain plates 501, and part of the chain plates 501 are omitted in the drawings for the purpose of showing the structure. In actuality, when the safety door 5 is in the closed state, the chain plates 501 seal the taking opening 101.

[0032] The safety door 5 is connected with a second driving mechanism, and the second driving mechanism drives the safety door 5 to rise and fall. The frame body 1 is provided with guide grooves 103 on both sides, and the safety door 5 is slidingly connected in the guide grooves 103. The second driving mechanism includes a motor 9, the motor 9 is connected with a first sprocket 10, and the same side of the frame body 1 is also provided with a second sprocket 11 and a third sprocket 12. The second driving mechanism further includes a chain, and the chain is connected on the first sprocket 10, the second sprocket 11 and the third sprocket 12. The motor 9 drives the first sprocket 10 to rotate, thereby driving the chain to move. Figure 6 As shown in the drawings, the chain plate 501 located at the lowermost end of the safety door 5 is connected with a lifting connecting rod 13, the lifting connecting rod 13 is connected with a chain hook 14 through the guide groove 103, and the chain hook 14 is hooked on the chain. Therefore, the movement of the chain drives the movement of the chain plate 501 to open and close the taking opening 101. In order to improve the stability of the lifting of the safety door 5, the first sprocket 10, the second sprocket 11, the third sprocket 12 and the chain can be provided on both sides of the frame body 1. The first sprockets 10 on both sides are coaxially moved by one motor, and the lifting connecting rod 13 and the chain hook 14 are provided on both sides of the chain plate 501 located at the lowermost end, so that the safety door 5 is lifted by traction on both sides, improving the stability of operation.

[0033] The lower end of the safety door 5 is movably provided with a touch strip 6, and the safety door 5 is further provided with a first micro switch. Specifically, the first micro switch is located in an assembly opening 5011 of a chain plate 501 at the lowermost end of the safety door 5, and the touch strip 6 is movably arranged in the assembly opening 5011 of the chain plate 501. The touch strip 6 is in movable connection with the first micro switch, and the first micro switch is electrically connected with a second driving mechanism. In a normal state, the touch strip 6 is in a separated state with the first micro switch. When the safety door 5 is falling, the touch strip 6 hits a human hand and rises relative to the chain plate 501. The collision of the touch strip 6 triggers the first micro switch, and the first micro switch transmits a signal to the second driving mechanism to stop driving the safety door 5, so that the safety door 5 stops moving, thereby achieving the effect of preventing hand clamping.

[0034] Specifically, the chain plate 501 at the lowermost end of the safety door 5 is longitudinally provided with a channel 5012, and the channel 5012 is in communication with the assembly opening 5011. A guide column 16 is movably connected in the channel 5012. The lower end of the guide column 16 is connected to the touch strip 6. The guide column 16 includes a limiting end plate 1601 located above. The diameter of the limiting end plate 1601 is greater than the hole diameter of the channel 5012, so that the guide column 16 cannot fall down, that is, the touch strip 6 is movably hung on the chain plate 501. The lower end of the guide column 16 has a recessed portion 1602, and the touch strip 6 is provided with a locking hole 601. During assembly, the guide column 16 is inserted into the touch strip 6 from top to bottom, and a screw is screwed into the locking hole 601 to abut against the recessed portion 1602 to lock the lower end of the touch strip 6 and the guide column 16, so that the touch strip 6 is hung on the chain plate 501.

[0035] The assembly opening 5011 is provided with a spring for pressing the touch strip 6 downward, so as to press the touch strip 6 downward. When the touch strip 6 touches a human hand, the upward movement of the touch strip 6 will compress the spring. After the human hand moves away, the downward movement of the spring will reset the touch strip 6.

[0036] The lowermost end of the guide groove 103 is provided with a second micro switch 15, and the second micro switch 15 corresponds to the position of the lifting connecting rod 13. The second micro switch 15 is electrically connected with the motor 9. When the chain plate 501 connected with the lifting connecting rod 13 falls to the lowest position, it is set that the safety door 5 completely seals the pickup opening 101 at this time. At this time, the lifting connecting rod 13 hits the second micro switch 15, the second micro switch 15 transmits a signal to the motor 9, and the motor 9 stops to stop pulling the chain, which is a clever structure.

[0037] When the taking-out port 101 is closed, the safety door 5 is lowered to separate the outer space of the device from the inner space of the device, and when the safety door 5 is lowered, the first micro switch at the lowermost part of the chain plate 501 at the lowermost part of the safety door 5 serves as a safety touch mechanism to prevent hand injury, when the taking-out port 101 is closed, the shielding cover 3 is in the lower position, and the finished product placing seat 2 becomes an open working area, which ensures that the internal work of the device is completely isolated from the outside of the device; when the device work is completed, the shielding cover 3 will be completely raised, and when the shielding cover 3 is completely raised, the safety door 5 is opened. When the safety door 5 is raised to the position, at this time, the shielding cover 3 and the finished product placing seat 2 form a window for taking out the product, and the safety door 5 and the shielding cover 3 can be reset after the product is taken out.

[0038] The food vending machine anti-pinch safety partition linkage shielding door mechanism is used in cooperation with the shielding cover 3, the touch strip 6 and the micro switch, so that the shielding cover 3 is raised to shield the finished product placing seat 2 when taking out the product, and the safety door 5 stops descending when the hand hits the touch strip 6, thereby achieving the anti-pinch effect, and the structure is ingenious and safe.

[0039] Finally, it should be noted that: the above is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application is described in detail with reference to the embodiments, for those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some technical features can be replaced, but any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
