Firstly, an operator inserts a wood board into a shell 2 through a through hole 3, then places a proper amount of valve port paper bags between a return type frame 7 and the shell 2, the valve port paper bags are contacted with the wood board, after the valve port paper bags are placed, the return type frame 7 is pushed to move downwards, the return type frame 7 moves downwards to drive a clamping mechanism 14 to move downwards, the clamping mechanism 14 is operated to clamp the valve port paper bags, the wood board can be drawn out from the shell 2, the return type frame 7 moves downwards to drive a u-shaped rod 6 to move downwards, the u-shaped rod 6 moves downwards to drive a sliding sleeve 5 to move downwards through a guide sleeve 10, a second spring 12 is stretched, meanwhile, the return type frame 7 also drives a first rack 9 to move downwards, when the first rack 9 moves downwards to be contacted with a driving mechanism 13, the return type frame 7 is stopped to be pushed, a hot air heater 8 is started, the hot air heater 8 blows hot air into the shell 2 to dry glue smearing positions of the valve port paper bags, and then, the driving mechanism 13 is started, the driving mechanism 13 operates to drive the first rack 9 to move left and right under the action of the first spring 11, the first rack 9 moves left and right to drive the die-returning frame 7 to move left and right, the die-returning frame 7 moves left and right to drive the valve port paper bag to move left and right through the clamping mechanism 14, and the valve port paper bag moves left and right to perform comprehensive drying. After glue on the valve port paper bag is dried, the driving mechanism 13 and the air heater 8 are closed, the molding frame 7 is loosened, the sliding sleeve 5 moves upwards to drive the u-shaped rod 6 to move upwards through the guide sleeve 10 under the action of the second spring 12, the u-shaped rod 6 moves upwards to drive the molding frame 7 to move upwards, the molding frame 7 moves upwards to drive the first rack 9 to move upwards to be separated from the driving mechanism 13, meanwhile, the molding frame 7 moves upwards to drive the valve port paper bag to move upwards through the clamping mechanism 14, when the molding frame 7 moves upwards to reset, the clamping mechanism 14 loosens the valve port paper bag, and an operator can take the dried valve port paper bag out of the shell 2. So, can paint glue department simultaneously to a plurality of valve port container bags and dry.

When an operator pulls the returning frame 7 to move downwards, when the first rack 9 moves downwards and is meshed with the sector gear 133, the pushing of the returning frame 7 is stopped, the clamping mechanism 14 also clamps and fixes the valve port paper bag, the hot air blower 8 is started to blow hot air to dry glue on the valve port paper bag, the driving motor 131 can be started to rotate forwards, the driving motor 131 rotates forwards to drive the transmission part 134 to rotate forwards, the transmission part 134 rotates forwards to drive the rotating shaft 132 to rotate forwards, the rotating shaft 132 rotates forwards to drive the sector gear 133 to rotate forwards, and due to the action of the first spring 11, the sector gear 133 rotates forwards to drive the first rack 9 to move left and right, so that the returning frame 7 drives the valve port paper bag to move left and right through the clamping mechanism 14 to perform comprehensive drying. After the glue on the valve port paper bag is dried, the driving motor 131 is closed, and the return frame 7 stops driving the valve port paper bag to move left and right.

Initially, the fourth spring 145 and the third spring 142 are in a stretched state, when an operator places the valve-port paper bag between the housing 2 and the paper-returning frame 7, the valve-port paper bag can be moved to between the two paper-returning clamp plates 146 corresponding to the hollow slider 143, and further, when the paper-returning frame 7 moves downward, the paper-returning frame 7 drives the movable rod 141 to move downward, the movable rod 141 moves downward to slide along the inner wall of the housing 2, the movable rod 141 moves leftward to drive the fixed block 147 to move leftward due to the action of the third spring 142, the fixed block 147 moves leftward without contacting the leftmost L-shaped rod 144, and due to the action of the fourth spring 145, the L-shaped rod 144 moves outward to drive the paper-returning clamp plates 146 to move inward, the paper-returning clamp plates 146 move inward to contact the valve-port paper bag to clamp the valve-port paper bag, and at the same time, the L-shaped rod 144 moves outward to move the hollow slider 143 leftward to uniformly arrange, so that each adjacent valve-port paper, the glue on the valve port paper bag can be dried. After the glue on the valve port paper bag is dried, the return frame 7 is released to move upwards and reset, the return frame 7 drives the movable rod 141 to move upwards, the movable rod 141 moves upwards and moves rightwards through the shell 2, the third spring 142 is stretched, the movable rod 141 moves rightwards to drive the fixed block 147 to move rightwards, the fixed block 147 moves rightwards to drive the L-shaped rod 144 to move rightwards, the L-shaped rod 144 moves rightwards to drive the hollow slide block 143 to move rightwards, meanwhile, the fixed block 147 also drives the L-shaped rod 144 to move inwards through the hollow slide block 143, the fourth spring 145 is stretched, the L-shaped rod 144 moves inwards to drive the return clamp plate 146 to move outwards, the return clamp plate 146 moves outwards to release the valve port paper bag, and an operator can take the valve port paper bag out.

Example 2

As shown in fig. 1, fig. 2 and fig. 6, the present embodiment is different from embodiment 1 mainly in that in the present embodiment, still including stop gear 15, stop gear 15 is including bull stick 151, rotary gear 152, slide bar 153, limiting plate 154, second rack 155 and fifth spring 156, the both sides are all connected with bull stick 151 of horizontal rotary type around base 1 top, bull stick 151 is located the guide arm 4 outside, bull stick 151 middle part rigid coupling has rotary gear 152, the rigid coupling has second rack 155 between the left and right sides guide pin bushing 10 medial surface, second rack 155 and rotary gear 152 cooperate, casing 2 front and back both sides lower part left and right sides all are slidingtype is equipped with slide bar 153, left and right sides slide bar 153 outer end respectively with both ends fixed connection about bull stick 151, the rigid coupling has limiting plate 154 that can be spacing to the valve port container bag between the left and right sides slide bar 153 inner, be connected with fifth spring 156 between slide bar 153 bottom and casing 2 inside.

When an operator puts the valve port paper bag between the shell 2 and the shape-returning frame 7, the valve port paper bag is contacted with the limit plate 154, the limit plate 154 enables the valve port paper bag to be placed, when the shape-returning frame 7 moves downwards, the sliding sleeve 5 moves downwards and also drives the second rack 155 to move downwards, when the second rack 155 moves downwards and is meshed with the rotating gear 152, the second rack 155 drives the rotating gear 152 to rotate inwards, the rotating gear 152 rotates inwards to drive the rotating rod 151 to rotate inwards, the rotating rod 151 rotates inwards to drive the sliding rod 153 to swing downwards, the fifth spring 156 is compressed, the sliding rod 153 moves downwards to drive the limit plate 154 to swing downwards, the limit plate 154 swings downwards and is separated from the valve port paper bag, meanwhile, the paper-returning clamping plate 146 also clamps and fixes the valve port paper bag, and when the paper-returning frame 7 stops moving downwards, the limiting plate 154 stops swinging downwards, so that the glue on the valve port paper bag can be dried. Similarly, after the glue on the valve port paper bag is dried, the returning frame 7 is released to move upwards for resetting, the second rack 155 moves upwards to drive the rotating gear 152 to rotate outwards, and when the second rack 155 is separated from the rotating gear 152, the slide rod 153 swings upwards to drive the limiting plate 154 to swing upwards for resetting under the action of the fifth spring 156. So, need not operating personnel and place the plank through-hole 3 and supply the valve port container bag to place in casing 2, it is more convenient.

Example 3
