[0021] In the embodiment, the sliding seat 17 is provided with a screw hole screwed with the lead screw 15, and two groups of vertical plates 14 are provided with sliding rods 21 penetrating through the sliding holes of the sliding seat 17.
[0022] In the embodiment, the air bag layer 7 is adhesively fixed on the inner bottom wall of the strip-shaped groove 6, the air bag layer 7 is provided with the elastic rope 22 connecting the upper and lower side walls thereof, the outer side of the base 3 is provided with the air inlet pipe and the air outlet pipe connected with the air bag layer 7, and the air inlet pipe is connected with the air pump.
[0023] As shown in the figure, Figure 2 The vertical section of the strip-shaped groove 6 is in the shape of an inverted isosceles trapezoid.
[0024] The working principle of the present application is that when the air bag layer 7 is exhausted during use, the elastic rope 22 is contracted to pull the upper half of the side wall to retract into the strip-shaped groove 6, at this time, the strip-shaped groove 6 with the upper part being larger and the lower part being smaller facilitates the sliding of the contracted air bag layer 7, and prevents the air bag layer 7 from protruding from the strip-shaped groove 6 and lifting the product in the groove 4;
[0025] Wherein after the product is placed in the groove 4, according to the adsorption area 5 covered by the product, the pipeline 11 connected with the adsorption cavity I 8 directly below the adsorption area 5 is opened, at this time the electromagnetic valve on the rest of the pipeline 11 is in a closed state, the adsorption area 5 covered in the above process may be a group or multiple groups, then the vacuum pump 12 works through the connecting pipe 13, the adsorption cavity II 9, the corresponding pipeline 11 and the adsorption cavity I 8 and the plurality of adsorption holes 10 located directly below the product to adsorb and fix the product, when the product is greater than a group of adsorption areas 5 in the above process, then the pipeline 11 and the adsorption cavity I 8 directly below the adsorption area 5 are opened, and the product can be adsorbed and fixed at the bottom of the groove 4 by vacuumizing, and when the product is greater than two groups or multiple groups of adsorption areas 5, similarly, the corresponding pipeline 11 and the adsorption cavity I 8 directly below the multiple groups of adsorption areas 5 are opened, and the product can be adsorbed and fixed at the bottom of the groove 4 by vacuumizing, and at this time the product bottom is subjected to multi-point adsorption to improve its stability, the pipeline 11, the adsorption cavity I 8 and the plurality of adsorption holes 10 corresponding to the adsorption area 5 directly below can be opened, and then the products of different sizes can be adsorbed and fixed by vacuumizing to ensure the stability of the product;
[0026] Wherein the motor 16 rotates on the slide 17 through the screw rod 15, so that the slide 17 moves left and right and moves in the same direction through the hydraulic rod 18 and the slide cylinder 19, and the dispensing mechanism 2 is driven downward by the slide cylinder 19 to perform dispensing work on the front side of the product at different positions in the transverse direction, and the slide cylinder 19 and the dispensing mechanism 2 can also be driven to move forward and backward by the hydraulic rod 18, so that the dispensing mechanism 2 can perform dispensing work on different areas of the product in the longitudinal direction, so that the dispensing mechanism 2 can perform dispensing work on different end faces of the top of the product in the above two ways;
[0027] When the product needs to be taken out after dispensing is completed, the air pump injects gas into the air bag layer 7 through the air inlet pipe to make it expand and stretch the elastic rope 22, wherein the top of the expanded air bag layer 7 slides out of the strip-shaped groove 6 to lift the bottom end of the product extending to the outside of the adsorption area 5, so that people can easily grab the product and take it down, at this time only the product area is greater than any one group of adsorption areas 6, then the inflated air bag layer 7 can lift it to make it easy to take down, in the above process, attention should be paid to the inflation speed of the air bag layer 7 to prevent it from inflating too fast and causing the air bag layer 7 to expand quickly to pop up the product.
