[0033] Reference Figure 3As shown, the conveying assembly 1 is used to convey the box body 9 to be covered, and the conveying assembly 1 includes a movable plate 11 and a limit seat 2. The limit seat 2 is connected to the movable plate 11, and the movable plate 11 can rotate. The movable plate 11 is annular as a whole, and the movable plate 11 is driven to rotate by a motor. The box body 9 to be covered is clamped with the limit seat 2, and the movable plate 11 rotates to drive the box body 9 to be covered to move. The movable plate 11 has an annular structure and a rotating conveying method, so that the assembly component 3, the first guide component 4 and the cover-covering component 5 can be arranged along the edge of the movable plate 11. Compared with the existing linear conveying method, the movable plate 11 has an annular structure and a rotating conveying method, so that the occupied area of ​​the box body cover-covering device is smaller.

[0034] Reference Figure 6 As shown, a plurality of limit seats 2 are equidistantly arranged along the edge of the movable plate 11, and the limit seats 2 include a connecting plate and a receiving member 21, and the receiving member 21 includes a receiving space for receiving the box body 9 to be covered, and openings are provided at both ends of the receiving member 21, and the openings are arranged along the radius of the movable plate 11, and the opening position of the box body 9 to be covered corresponds to the opening of the receiving member 21, and the size of the receiving space corresponds to the main body of the box body 9 to be covered, and the first end plate 91 and the second end plate 94 of the box body 9 to be covered can extend from the opening of the receiving member 21 away from the rotation axis of the movable plate 11, and the third end plate 97 of the box body 9 to be covered can extend from another opening of the receiving member 21. When the box body 9 to be covered is located in the receiving space, the first end plate 91 and the third end plate 97 are located at the top of the box body 9 to be covered, and the second end plate 94 is located at the bottom of the box body 9 to be covered. The bottom of the container 21 is connected to the connecting plate, and the connecting plate and the two sides corresponding to the side walls of the container 21 are hinged with a blocking rod 22, which is U-shaped as a whole, and the end of the blocking rod 22 is rotatably connected to a roller 23, which abuts against the external boss, so that the blocking rod 22 can rotate into the accommodation space, and then the top of the blocking rod 22 can extend into the accommodation space and abut against the top of the main body of the box body 9 to be locked in the accommodation space, at this time, the box body 9 to be locked is clamped with the limiting seat 2 and fixed in position. Preferably, a stopper 24 is also connected to the connecting plate, and the stopper 24 can abut against the blocking rod 22, so as to limit the rotation angle of the blocking rod 22.

[0035] Reference Figure 5As shown, the assembly component 3, the first guide component 4 and the cover assembly 5 are sequentially arranged along the conveying path of the conveying component 1. The assembly component 3 includes a flipping mechanism and a shaping mechanism. The flipping mechanism includes a top plate 32 that can move toward the edge of the conveying component 1. Specifically, the flipping component also includes a first driving member 31. The top plate 32 is connected to the output end of the first driving member 31. The first driving member 31 is fixed to the outside through a first mounting bracket 33. The assembly component 3 is located below the movable plate 11. The first driving member 31 can drive the top plate 32 to rise and move toward the edge of the movable plate 11. The moving path of the top plate 32 is perpendicular to the movable plate 11. When the top plate 32 is in an extended state, there is a gap between the top plate 32 and the edge of the movable plate 11. The top of the top plate 32 and the side of the top plate 32 facing the feeding direction of the conveying component 1 are both arc-shaped. After the second end plate 94 of the box body 9 to be covered is abutted against the top plate 32, it will be guided by the arc-shaped side and will tilt up. Then the first driving member 31 drives the top plate 32 to quickly descend and then rise again. Since the second end plate 94 will remain in the tilted state for a certain period of time after losing the support of the top plate 32, when the second end plate 94 starts to rotate downward, the top plate 32 again abuts against the second end plate 94 and drives the second end plate 94 to fold upward, so that the second end plate 94 is located close to the opening position of the box body 9 to be covered.

[0036] The shaping mechanism includes a baffle 39 and a movable pressing plate 36, and the pressing plate 36 can bend the tongue extending from the baffle 39 to the conveying assembly 1 on the cover box body 9 to be buckled. Specifically, the shaping mechanism also includes a second driving member 35 and a third driving member 37, and the second driving member 35, the third driving member 37 and the baffle 39 are all fixed to the outside through the second mounting frame 34. The baffle 39 is L-shaped as a whole, and the position of the baffle 39 used to abut against the first end plate 91 extends along the tangent of the moving path of the movable plate 11, so that after the first end plate 91 abuts against the baffle 39, the edge of the baffle 39 away from the conveying assembly 1 corresponds to the connection position of the first end plate 91 and the first tongue 92. The pressing plate 36 is connected to the output end of the second driving member 35, and the moving path of the pressing plate 36 is perpendicular to the plane where the movable plate 11 is located. The output end of the third driving member 37 is connected to the first push plate 38, and the moving path of the first push plate 38 is parallel to the plane where the movable plate 11 is located. When the first push plate 38 is in the extended state, the first push plate 38 is located below the baffle 39 and there is a gap between the first push plate 38 and the baffle 39. The pressing plate 36 can extend between the first push plate 38 and the baffle 39, and when the pressing plate 36 is in the extended state, there is a gap between the pressing plate 36 and the baffle 39. After the first end plate 91 of the cover box body 9 is located on the baffle 39, the second driving member 35 drives the pressing plate 36 to press down and bend the first latch 92, so that the first latch 92 and the first end plate 91 are in a vertical state, and then the pressing plate 36 retracts, and the third driving member 37 drives the first push plate 38 to bend the first latch 92 again, so that the first latch 92 is bent in the direction close to the conveying assembly 1, and at this time, the first latch 92 and the first end plate 91 form an acute angle.

[0037] The first guide assembly 4 includes a guide seat 41, a first guide rod 44, a first guide plate 42, and a second guide plate 43. The first guide plate 42 and the second guide plate 43 are both connected to the guide seat 41, and the first guide rod 44 is connected to the external bracket. The edges of the first guide rod 44, the first guide plate 42, the second guide plate 43, and the guide seat 41 close to the conveying assembly 1 all extend along the conveying path of the movable plate 11 in the conveying assembly 1, that is, the first guide rod 44, the first guide plate 42, the second guide plate 43, and the guide seat 41 are all arc-shaped. The first guide plate 42 is located on the guide seat 41 close to the edge of the conveying assembly 1, the end of the second guide plate 43 close to the shaping mechanism corresponds to the shaping position of the shaping mechanism, the end of the first guide rod 44 close to the baffle 39 corresponds to the position of the end of the baffle 39 close to the first guide rod 44, and the end of the first guide rod 44 close to the baffle 39 is higher than the end of the first guide rod 44 close to the baffle 39. After the first latch 92 is bent, the movable plate 11 drives the box body 9 to be covered to move, and the first end plate 91 and the first latch 92 can enter the guide space formed between the first guide rod 44 and the guide seat 41 through the gap between the first guide rod 44 and the baffle 39. The connection position between the first end plate 91 and the first latch 92 abuts against the second guide plate 43, thereby preventing the first latch 92 from rebounding, so that the first latch 92 can continue to maintain the bent state during the movement; at the same time, the hanging plate 93 abuts against the position of the first guide rod 44 away from the guide seat 41, so that the angle between the hanging plate 93 and the first end plate 91 will not be too small, avoiding the angle between the hanging plate 93 and the first end plate 91 being too small to affect the subsequent cover-covering action. Preferably, the minimum angle between the hanging plate 93 and the first end plate 91 is greater than 30°. The end of the first guide plate 42 corresponds to the folding position of the second end plate 94. After the flipping mechanism completes the folding of the second end plate 94, the movable plate 11 drives the box body 9 to be covered to move, and the second end plate 94 is against the first guide plate 42, so that the second end plate 94 can maintain the folded state during the movement.

[0038] The end of the first guide plate 42 close to the assembly component 3 is provided with a third guide plate 45 extending in a direction away from the conveying component 1. The plane where the first guide plate 42 is located is at an obtuse angle to the plane where the third guide plate 45 is located, that is, the third guide plate 45 is inclined, which can guide the movement of the second end plate 94 and can also position the second end plate 94 so that the second end plate 94 is closer to the opening of the box body 9 to be covered. The side of the second guide plate 43 close to the guide seat 41 is connected to the fourth guide plate 46, which extends in a direction close to the conveying component 1. The plane where the second guide plate 43 is located is at an obtuse angle to the plane where the fourth guide plate 46 is located, so that during the movement of the first end plate 91, the first latch 92 can be abutted against the fourth guide plate 46, thereby further preventing the first latch 92 from rebounding and allowing the first latch 92 to remain in a bent state.

[0039] The cover-locking assembly 5 is located at one end of the first guide assembly 4 away from the assembly assembly 3. The cover-locking assembly 5 includes a push rod capable of squeezing the tongue. Specifically, the cover-locking assembly 5 includes a fourth driving member 51 and a fifth driving member 53. The push rod includes a first push rod 52 and a second push rod 54. The output end of the fourth driving member 51 is connected to the first push rod 52, and the output end of the fifth driving member 53 is connected to the second push rod 54. The fourth driving member 51 and the fifth driving member 53 are fixed to the outside through a third mounting bracket. The distance between the first push rod 52 and the second push rod 54 close to the conveying assembly 1 gradually increases in the direction close to the conveying assembly 1, that is, a V-shaped space is formed between the first push rod 52 and the second push rod 54 close to the conveying assembly 1. The distance between the first push rod 52 and the second push rod 54 corresponds to the width of the first latch 92. The fourth driving member 51 drives the first push rod 52 to abut against one end of the first latch 92 and squeeze the first latch 92, so that one end of the first latch 92 first extends into the bayonet 95, and then the fifth driving member 53 drives the second push rod 54 to abut against one end of the second latch 98, so that the first latch 92 is completely extended into the bayonet 95. The extension of the entire latch into the bayonet 95 can also fix the position of the second end plate 94. The distance between the first push rod 52 and the second push rod 54 close to one end of the conveying component 1 gradually increases toward the direction close to the conveying component 1, so that one end of the first latch 92 can enter the bayonet 95 obliquely and tilted, so that the first latch 92 can enter the bayonet 95 which is smaller than the width of the first latch 92.

[0040] Reference Figure 7 As shown, the middle position of the movable plate 11 is slidably connected with a mounting plate 12, and the mounting plate 12 is fixed to the outside. The mounting plate 12 is also provided with a second limit assembly 6, and the second limit assembly 6 includes a sixth driving member 61, and the sixth driving member 61 is connected to the mounting plate 12.

The second push plate 62 is arranged opposite to the shaping mechanism, so as to simultaneously complete the folding of the third end plate 97, the bending of the first latch 92, and the folding of the second end plate 94.

[0041] The second limiting assembly 6 also includes a second guide rod 63 and a fifth guide plate 64, which are fixedly connected to the mounting plate 12, and are arranged along the conveying path of the movable plate 11, and the ends of the second guide rod 63 and the fifth guide plate 64 correspond to the folding path of the third end plate 97. After the third end plate 97 completes the folding, the movable plate 11 drives the third end plate 97 to move, and the third end plate 97 is abutted against the second guide rod 63 and is located between the second guide rod 63 and the fifth guide plate 64, so that the third end plate 97 can maintain a folded state, and the second rocking leaf 99 can also maintain a folded state.
