In order to prevent the fixed folding wing rod 51 from damaging the surface of the material, the feed end of the fixed folding wing rod 51 can be tilted to expand its entrance to facilitate the entry of the material side wings, and at the same time, the outlet of the fixed folding wing rod 51 can be extended to the tongue-inserting capping mechanism 7 to continuously limit the side wings to prevent them from rebounding.

[0028] The frame 1 is also provided with a locking tongue mechanism, which is arranged between the folding wing mechanism 5 and the top cover pre-folding mechanism 6. The locking tongue mechanism includes a locking tongue push rod 111 and a locking tongue driving component that drives the locking tongue push rod 111 to extend and retract. The locking tongue push rod 111 is arranged to be tilted downward, and the locking tongue push rod 111 is arranged above the conveying channel 23. The projection line of the locking tongue push rod 111 is perpendicular to the material conveying direction, that is, the locking tongue push rod 111 is arranged in the front and rear direction and tilted downward, so that it does not interfere with the top cover of the material, and can smoothly push down the locking tongue 106. The locking tongue mechanism also includes a locking tongue limiting plate 114, which is arranged in front of the locking tongue push rod 111, and a limiting channel for the locking tongue 106 to pass through is provided below the locking tongue limiting plate 114. The locking tongue push rod 111 is transmission-connected to a locking tongue servo adjustment mechanism that drives it to adjust left and right, and the locking tongue servo adjustment mechanism is connected to the controller 8. The lock tongue servo adjustment mechanism can drive the lock tongue push rod 111 to automatically adjust according to the position of the lock tongue 106 of the material.

[0029] The top cover pre-folding mechanism 6 includes a first push rod 61 for pre-folding the rear top cover 103 of the material, the first push rod 61 is in transmission connection with the cover push driving component that drives it to move forward and backward to push the material, the power source of the cover push driving component can be a cylinder or a motor, the top cover pre-folding mechanism 6 is arranged behind the tongue plugging and capping mechanism 7, the first push rod 61 extends out to push down the vertically set rear top cover 103, and facilitates the subsequent folding of the tongue plugging 105. In order to adapt to more materials of different specifications, the top cover pre-folding mechanism 6 also includes a second push rod 63 for pushing and folding the front top cover 104 of the material, the second push rod 63 is arranged in front of the first push rod 61, and the second push rod 63 is in transmission connection with the front side cover push driving component that drives it to move forward and backward, and in order to avoid abrasion of the material surface, the second push rod 63 can appear in the form of a roller. In order to avoid the top cover from shifting, the top cover pre-folding mechanism 6 also includes a top cover positioning rod 62 for limiting the top cover 103 on the rear side of the material. The top cover positioning rod 62 is arranged downstream of the first push rod 61. After the material passes through the first push rod 61 to pre-fold its top cover, it enters under the top cover positioning rod 62. The top cover positioning rod 62 is arranged above the push plate. There is a folding space under the top cover positioning rod 62 for the insert tongue 105 to fold. The top cover positioning rod 62 has a horizontal positioning part and an inclined material guiding part. The inclined material guiding part makes the entrance of the top cover positioning rod 62 convergent, that is, the opening of the inclined guide part along the conveying direction is from large to small, so that the material top cover can smoothly enter under the top cover positioning rod 62 to position the material top cover.

[0030] The insert tongue 105 mechanism includes an insert tongue pressing plate 71 and a positioning plate 72, wherein the positioning plate 72 is arranged below the insert tongue pressing plate 71, wherein the positioning plate 72 has a vertical positioning surface, and the insert tongue pressing plate 71 has a vertical guide surface, wherein the positioning plate 72 is connected in a transmission manner to the insert tongue servo positioning mechanism that drives it to move left and right, and the controller 8 controls the insert tongue servo positioning mechanism to drive the positioning plate 72 to move accordingly according to the position of the insert tongue 105 of the material. The insert tongue pressing plate 71 is connected in a transmission manner to a tongue folding driving component that drives it to descend to perform a tongue folding action, and the insert tongue pressing plate 71 is pressed downward to fold the insert tongue 105 until the insert tongue 105 contacts the vertical positioning surface of the positioning plate 72 and is turned into place, thereby ensuring the qualified rate of the product. The insert tongue 105 mechanism also includes a top cover pressure plate 73, which is arranged above the conveying channel 23, and is connected to a cover driving member that drives it to descend to perform a cover pressing action. Specifically, a mounting plate is provided on the frame 1, and a first vertical guide rail and a second vertical guide rail are provided on both sides of the mounting plate, respectively. The top cover pressure plate 73 is slidably arranged on the first vertical guide rail, and the insert tongue pressure plate 71 is slidably arranged on the second vertical guide rail. The top cover pressure plate 73 descends so that the insert tongue 105 is inserted into the material box body along the vertical guide surface of the insert tongue pressure plate 71 to complete the box sealing. In addition, the positioning plate 72 includes an avoidance state and a working state. In the working state, the positioning plate 72 cooperates with the insert tongue pressure plate 71 to fold the tongue. In the avoidance state, the positioning plate 72 moves away from the material to avoid the top cover pressure plate 73. The insert tongue servo positioning mechanism adjusts the working state position of the positioning plate 72 according to the specifications of the material, and the adjustment is fast and convenient.

[0031] For materials with a high height, the box mouth of the material is easily deformed, which makes the tongue 105 unable to be smoothly inserted, and a box body positioning component is further provided. The tongue 105 mechanism also includes a box body positioning component, and the box body positioning component includes a top box plate 91 and a correction swing plate 94. The top box plate 91 is connected to the telescopic drive member, and the telescopic drive member drives the top box plate 91 to move forward into the conveying channel 23. The telescopic drive member is arranged on a moving block 911, and the moving block 911 is connected to the servo follower drive mechanism, and the servo follower drive mechanism is connected to the controller 8. The top box plate 91 is arranged above the conveying channel 23, and the servo follower drive mechanism drives the top box plate 91 to move to the front of the material moving direction to resist the upper end of the material. The correction swing plate 94 is swingably arranged below the conveying channel 23, and the correction swing plate 94 is connected to the swing drive member. The power source of the swing drive member can be a telescopic cylinder, and the correction swing plate 94 is arranged on a rotating shaft, and the rotating shaft is fixedly arranged at one end of the swing rod, and the other end of the swing rod is hinged to the telescopic cylinder. Of course, the power source of the swing drive member can also be a motor. During operation, the top box plate 91 extends out to cooperate with the correction swing plate 94 to correct the material. The top box plate 91 acts on the upper end of the material, and the correction swing plate 94 acts on the lower end of the material to cooperate in correcting the material, thereby further improving the product qualification rate. Example 1

[0032] During the adjustment, the length, width, height and size data of the material and the tongue 105 are input into the human-machine interface of the controller 8, and the controller 8 controls the box width servo adjustment mechanism 31, the box height servo adjustment mechanism 41 and the tongue servo positioning mechanism to realize automatic adjustment. The box width servo adjustment mechanism 31 controls the front toothed conveying mechanism 21 and the rear toothed conveying mechanism 22 to move relative to each other forward and backward, and adjusts the distance between the two according to the box width of the material. The box height servo adjustment mechanism 41 drives the lifting support seat 4 to move up and down according to the box width of the material. The tongue servo positioning mechanism automatically adjusts the position of the positioning plate 72 in the working state.

[0033] When the box is sealed, the material is placed between the first push plate 211 and the second push plate 221 to push the material forward, and the fixed folding wing rod 51 pushes the right wing 102 of the material being transported to fold the right wing 102 of the material. Then, the material stops moving, and the movable folding wing rod 52 pushes and folds the left wing 101 downward. The material continues to move, so that the left wing 101 enters under the fixed folding wing rod 51. The fixed folding wing rod 51 positions the left and right side wings 102 at the same time. When the material moves to the front of the first push rod 61, the first push rod 61 extends to fold the rear top cover 103 of the material. In order to prevent the rear top cover 103 of the material from rebounding due to the elasticity or tension of the material after folding, the material continues to move to the bottom of the top cover positioning rod 62. The top cover positioning rod 62 limits the rebound degree of the rear top cover 103 of the material and positions the rear top cover 103. The material continues to move to the bottom of the top cover pressure plate 73. To ensure the smooth insertion of the tongue 105, the correction swing plate 94 swings to the right side of the material. The servo follower drive mechanism drives the top box plate 91 to move to the front of the material moving direction. After it hits the left side of the material, the correction swing rod cooperates with the top box plate 91 to correct the material until the material reaches the position of the tongue 105 and stops moving. The top box plate 91 then drives the positioning plate 72 to move to the position (i.e., below the position of the material tongue 105) by the tongue servo positioning mechanism. The tongue pressure plate 71 descends to fold the tongue 105 until it contacts the vertical guide surface of the positioning plate 72 to ensure that the tongue 105 is folded in place. The tongue servo positioning mechanism drives the positioning plate 72 to enter the avoidance state. The positioning plate 72 leaves the material. The top cover pressure plate 73 descends again to insert the tongue 105 into the material box along the guide surface of the tongue pressure plate 71 to complete the box sealing. After the automatic box sealing is completed, the correction swing rod swings back to reset, and the top box plate 91 retracts and resets to wait for the subsequent conveyed materials. Example 2

[0034] For example Figure 7When the material shown is sealed, when the human-machine interface input device is adjusted according to the box height and box width specifications, the controller 8 controls the lock tongue servo adjustment mechanism to adjust the position of the lock tongue push rod 111 according to the position of the lock tongue 106. On the basis of Example 1, after the left and right side wings 102 of the material are folded, the lock tongue push rod 111 extends to push down the lock tongue 106, and then the material continues to move, and the lock tongue 106 enters the limiting channel under the lock tongue limiting plate 114, and then the rear top cover 103 is folded and the insertion tongue 105 is inserted. The action is the same as the embodiment, and it will not be repeated here. Example 3

[0035] On the basis of Example 2, the lock tongue 106 enters the limiting channel after being pushed down, and the second push rod 63 first pushes and folds the front top cover 104 of the material. After pushing and folding, the controller 8 controls the tongue servo positioning mechanism to drive the positioning plate 72 to move to the top of the front top cover 104 to position the front top cover 104 to prevent the front top cover 104 from rebounding. Then the first push rod 61 extends out to push and fold the rear top cover 103. After the pushing and folding is completed, the material enters the position of the material tongue 105, and the positioning plate 72 moves with the material. Then the action of the material tongue 105 is the same as in Example 1, which will not be repeated here.
