The working principle is as follows: firstly, as shown in fig. 1, when the valve rod 20 is lifted to the limit position, the upper end of the vertical plate 22 is attracted by the third magnet 35 and abuts against the third magnet 35, the lower end of the vertical plate 22 is separated from the right port of the flow inlet channel 21, that is, the flow inlet channel 21 communicates the dosing cylinder 18 with the glue cylinder 15, so that the glue in the glue cylinder 15 can flow through the flow inlet channel 21 on the side wall of the dosing cylinder 18 and enter the dosing cylinder 18, and the dosing cylinder 18 is filled with the glue;
then, the valve rod 20 moves downwards under the driving of the power device, once the valve rod 20 descends, the valve rod 20 drives the first gear 40 to rotate through the sixth gear 41, the first gear 40 drives the baffle 37 to descend through transmission with the baffle 37, the baffle 37 can push the third pressure spring 39 to contract, namely, the repulsive force between the baffle 37 and the vertical plate 22 is larger than the attractive force between the third magnet 35 and the fourth magnet, so that the baffle 37 can push the vertical plate 22 to be separated from the attractive force of the third magnet 35, the vertical plate 22 is abutted against the inner wall of the glue barrel 15 under the driving of the baffle 37, and the vertical plate 22 can block the right end opening of the flow inlet channel 21, the vertical plate 22 blocks the communication between the quantitative barrel 18 and the glue barrel 15, so that the quantitative barrel 18 and the glue barrel 15 form two independent closed spaces; meanwhile, in the descending process of the valve rod 20, the upper end of the valve rod 20 is separated from the left end of the flat plate 26, the flat plate 26 is driven by the return tension spring 49 to rotate counterclockwise, the arc-shaped rack 27 at the right end of the flat plate 26 drives the second gear 55 to rotate, the second gear 55 drives the third gear 56 to rotate, the third gear 56 drives the transmission plate 53 to ascend, the transmission plate 53 drives the push plate 51 to slide rightwards through the fourth gear 57, and therefore the left end of the push plate 51 can be drawn out from the lower end of the charging barrel 50 to enable the workpiece 29 in the charging barrel 50 to fall onto the workbench 28;
after the communication between the dosing cylinder 18 and the glue cylinder 15 is cut off, the descending of the valve rod 20 increases the pressure inside the dosing cylinder 18 through the diaphragm 19, the glue in the dosing cylinder 18 can be extruded out from the lower end discharge port 25 along with the descending of the diaphragm 19, the ascending pressure in the dosing cylinder 18 can also push the swing plate 42 to overcome the tension action of the locking tension spring 43 and separate from the lower end discharge port 25 of the dosing cylinder 18, namely the glue in the dosing cylinder 18 falls from the discharge port 25 to the surface of the workpiece 29 on the workbench 28;
after the primary spraying is finished, the valve rod 20 is lifted and reset, and the swinging plate 42 is driven by the locking tension spring 43 to abut against the discharge hole 25 at the lower end of the quantitative cylinder 18 again; along with the rising of the valve rod 20, the valve rod 20 drives the baffle 37 to rise and reset through the sixth gear 41 and the first gear 40, the elasticity of the third pressure spring 39 to the vertical plate 22 is reduced, and once the vertical plate 22 loses the constraint of the elasticity of the third pressure spring 39, the vertical plate 22 rises under the attraction force of the third magnet 35 and the fourth magnet until the upper end of the vertical plate 22 abuts against the third magnet 35; the upper end of the valve rod 20 pushes against the flat plate 26 to rotate clockwise, the right end of the valve rod 20 sequentially passes through the arc-shaped rack 27, the second gear 55 and the third gear 56 to drive the transmission plate 53 to descend, the transmission plate 53 drives the push plate 51 to move leftwards through the fourth gear 57, so that the left end of the push plate 51 pushes against the workpiece 29 which is tightly pressed against the workbench 28 in the material barrel 50 to slide leftwards, namely, each time the push plate 51 slides in a reciprocating manner, the push plate can push one workpiece 29 in the material barrel 50 to feed a station leftwards;
wherein, the operating principle of the annular guide rail 1 and the deflector rod 3 is as follows: when the roller 4 on the shift lever 3 is located at the first horizontal section 1.1, originally, the annular protrusion 9 at the right end of the shift lever 3 is under the action of the second pressure spring 5 to drive the shift lever 3 to be located at the right limit position of the first horizontal section 1.1, but when the shift lever 3 is located at the first horizontal section 1.1, the second magnet at the left end of the shift lever 3 is attracted by the first magnet 2 on the base 14 to drive the shift lever 3 to slide leftwards, that is, the shift lever 3 is pulled to the left limit position to enable the roller 4 at the left end of the shift lever 3 to be abutted against the left inclined plane of the first inclined section 1.2; then, when the valve rod 20 descends, the shift lever 3 descends along with the valve rod 20, but the left end of the shift lever 3 is constrained by the first inclined section 1.2, so that the roller 4 at the left end of the shift lever 3 rolls in the first inclined section 1.2 along the length direction of the first inclined section 1.2, that is, the shift lever 3 is displaced leftwards relative to the valve rod 20, and the tip structure 7 at the right end of the shift lever 3 is completely separated from the bump 6 on the right guide sleeve 8; with the continuous descending of the valve rod 20, the roller 4 at the left end of the shift lever 3 descends along the first vertical section 1.3; once the roller 4 enters the second horizontal section 1.4, the annular bulge 9 at the right end of the shift lever 3 is under the elastic action of the second pressure spring 5 to drive the shift lever 3 to slide rightwards, so that the right end of the shift lever 3 is clamped on the convex block 6 on the side wall of the guide sleeve 8; when the valve rod 20 is reset upwards, the roller 4 at the left end of the shifting rod 3 rolls in the second vertical section 1.5, and the pointed structure 7 at the right end of the shifting rod 3 is clamped with the bump 6, so that the shifting rod 3 can drive the guide sleeve 8 to gradually rise, the guide sleeve 8 drives the support 13 and the sliding plate 23 to descend through the fifth gear 12, and further the first pressure spring 24 is compressed to deform or the cover plate is pushed to descend through the first pressure spring 24, so that the pressure in the glue cylinder 15 is raised in a word, and glue in the glue cylinder 15 can conveniently enter the quantitative cylinder 18; when the roller 4 enters the second inclined section 1.6, the shifting lever 3 gradually slides leftwards along with the rising of the valve rod 20, so that the pointed structure 7 at the right end part of the shifting lever 3 is separated from the lug 6 until the roller 4 enters the first horizontal section 1.1 and enters the next cycle; that is, when the valve rod 20 descends, the shift lever 3 slides along the first inclined section 1.2 and the first vertical section 1.3, the pointed structure 7 at the right end of the shift lever 3 is separated from the bump 6, and the guide sleeve 8 cannot be driven to slide downwards; when the valve rod 20 ascends, the deflector rod 3 slides along the second vertical section 1.5 so that the tip structure 7 at the right end of the deflector rod 3 is clamped with the lug 6 to drive the guide sleeve 8 to ascend together, and the deflector rod 3 slides along the second inclined section 1.6 so that the tip structure 7 at the right end of the deflector rod 3 is separated from the lug 6, so that the one-way sliding of the guide sleeve 8 is realized, and the one-way sliding of the support 13 and the sliding plate 23 is further realized; in addition, the pawl 10 and the fifth gear 12 are matched to prevent the guide sleeve 8 from reversely resetting automatically, so that the working stability and reliability of the whole device are improved; in the structure of the ring rail 1, two points need to be described in detail: firstly, the attractive force of the first magnet 2 and the attractive force of the second magnet are matched so as to overcome the elastic force of the second pressure spring 5 and pull the roller 4 to enter the first inclined section 1.2 from the first horizontal section 1.1; secondly, the arrangement of the second inclined section 1.6 can enable the roller 4 to enter the first horizontal section 1.1 from the second vertical section 1.5 along the second inclined section 1.6, so that the ascending distance of the guide sleeve 8 along with the valve rod 20 can be reduced, the stroke of the guide sleeve 8 is prevented from being consistent with that of the valve rod 20, and the overlarge stroke and the overlong length of the guide sleeve 8 are further prevented, namely, the ascending stroke of the guide sleeve 8 is smaller than that of the valve rod 20 when the valve rod 20 ascends each time; that is, the matching between the shift lever 3 and the guide sleeve 8 can be more flexible by matching the annular guide rail 1 with the roller 4 on the shift lever 3.

Any modification, equivalent replacement, and improvement made within the scope of the claims of the present invention should be included in the protection scope of the present invention.
