Description

Technical Field

[0001] The present invention relates to the technical field of carton sealing edge devices, and particularly to a movable edge blocking unit. Background Art

[0002] In the existing carton sealing production line, when aligning cartons, generally a stop bar is set at the conveying roller surface. The cartons are pushed to the stop bar so that the side edges of the cartons are flush with the stop bar, thus completing the alignment of the cartons and facilitating the next processing step for the cartons. However, the existing stop bar cannot be adjusted and cannot provide a让位 during conveying. During conveying, the end of the stop bar is prone to collide with the cartons, affecting the appearance of the cartons, thereby affecting the production qualification rate. At the same time, the installation and disassembly of the stop bar are relatively troublesome. Summary of the Invention

[0028] See also Figures 1 to 3 As shown, a movable sidewall unit of this embodiment includes a fixed seat 1, a movable frame 2, a movable guide mechanism 3, a rotation drive mechanism 4 and a rotating seat 5;

[0029] The movable frame 2 is arranged on the fixed seat 1, and the movable guide mechanism 3 is arranged between the fixed seat 1 and the movable frame 2;

[0030] The rotation driving mechanism 4 is movably installed on the moving frame 2, the rotating seat 5 is hinged to the moving frame 2, one end of the rotating seat 5 is hinged to the output end of the rotation driving mechanism 4, and the other end of the rotating seat 5 rotates around the hinged portion between the rotating seat 5 and the moving frame 2.

[0031] With this structure, the moving frame 2 moves on the fixed seat 1 through the moving guiding mechanism 3. During use, according to actual needs, the moving direction of the moving guiding mechanism 3 can be set to be parallel to the direction to be detected. By setting the rotation driving mechanism 4 and the rotating seat 5, the rotation driving mechanism 4 drives the rotating seat 5 to rotate, so that one end of the rotating seat 5 is erected or flattened. When erected, it cooperates with the external clamping device to fix the box body. When flattened, it can prevent the situation that the rotating seat 5 blocks the movement of the box body, thus playing the role of a movable edge.

[0032] Preferably, the moving frame 2 includes a first bracket 21, a connecting frame 22 and a second bracket 23. The cross-sections of the first bracket 21 and the second bracket 23 are both C-shaped structures, and the openings of the first bracket 21 and the second bracket 23 both face the fixed seat 1. One end of the connecting frame 22 is connected to the first bracket 21, and the other end of the connecting frame 22 is connected to the second bracket 23.

[0033] With this structure, the first bracket 21, the connecting frame 22 and the second bracket 23 cooperate to form the moving frame 2, which moves around the fixed seat 1, and the moving direction is the length direction of the moving guiding mechanism 3. The first bracket 21 and the second bracket 23 adopt C-shaped structures, which can provide a让位 space for the fixed seat 1, play a certain positioning and guiding role, and also save installation space.

[0034] Preferably, the rotating seat 5 is hinged to the upper end of the second bracket 23, and the rotation driving mechanism 4 is movably installed on the first bracket 21. The rotation driving mechanism 4 drives the rotating seat 5 to rotate around the hinged part of the rotating seat 5 and the second bracket 23.

[0035] With this structure, the rotation driving mechanism 4 is movably installed on the first bracket 21, and the rotating seat 5 is hinged to the second bracket 23, which can ensure that when the output end of the rotation driving mechanism 4 extends or contracts, it can flexibly drive the rotating seat 5 to rotate, preventing jamming or inflexible rotation.

[0036] Preferably, the rotation driving mechanism 4 includes a rotation driving cylinder 41, a connecting sleeve 42 and a hinge seat 43. The rotation driving cylinder 41 is hinged to the first bracket 21, the output end of the rotation driving cylinder 41 is connected to the connecting sleeve 42, and the connecting sleeve 42 is connected to the hinge seat 43; the hinge seat 43 is hinged to one end of the rotating seat 5.

[0037] With this structure, the rotation driving cylinder 41, the connecting sleeve 42 and the hinge seat 43 cooperate to play a role of flexible rotation, ensuring that when the rotation driving cylinder 41 extends or contracts, it can flexibly drive the rotating seat 5 to rotate.

[0038] Preferably, it also includes an in-place detection mechanism 6, a mounting plate 231 is provided on one side of the lower end of the second bracket 23, the mounting plate 231 is provided with a strip hole 232 along the length direction, the in-place detection mechanism 6 is arranged on the fixing seat 1, and the upper end of the in-place detection mechanism 6 passes through the strip hole 232; the in-place detection mechanism 6 is a photoelectric switch.

[0039] In this embodiment, the model of the photoelectric switch is QKRA8. With this structure, when the second bracket 23 moves, the strip hole 232 provides a way for the photoelectric switch. When working, the rotating seat 5 rotates to an upright state, and the side of the box pushes the rotating seat 5 to drive the moving frame 2 to move. The moving frame 2 moves along the length direction of the moving guide mechanism 3. When it moves to a certain distance and the side of the box is detected by the photoelectric switch, it stops pushing the box, thereby completing the positioning of the box.

[0040] Preferably, it further comprises a travel limit mechanism 7, which is arranged on the fixing seat 1, and a stopper 233 is arranged on the other side of the lower end of the second bracket 23, and the detection end of the travel limit mechanism 7 is opposite to the stopper 233. Preferably, the travel limit mechanism 7 is a travel switch; the model of the travel switch is WLCA2.

[0041] With this structure, when the photoelectric switch fails or is damaged, the box continues to move after passing the position detected by the photoelectric switch, and the block 233 pushes the detection end of the travel limit mechanism 7. When the travel limit mechanism 7 moving frame 2 detects the preset moving distance, an alarm is issued and the box is stopped from being pushed.

[0042] Preferably, the movable guide mechanism 3 comprises a guide hole 31, a guide rod 32, a linear bearing 33, a telescopic spring 34, a first locking screw 35 and a second locking screw 36;

[0043] The guide hole 31 is horizontally arranged in the fixing seat 1, the guide rod 32 is movably inserted in the guide hole 31, the linear bearing 33 is arranged between the outer wall of the guide rod 32 and the inner wall of the guide hole 31, one end of the guide rod 32 extends to the outside of the guide hole 31, and is locked and connected with the first bracket 21 through the first locking screw 35, the other end of the guide rod 32 extends to the outside of the guide hole 31, and is locked and connected with the second bracket 23 through the second locking screw 36, the telescopic spring 34 is sleeved on the periphery of the guide rod 32, one end of the telescopic spring 34 is connected to the fixing seat 1, and the other end of the telescopic spring 34 is connected to the second bracket 23.

[0044] With this structure, the guide rod 32, the linear bearing 33 and the guide hole 31 cooperate to play a good guiding role, so that the moving frame 2 can keep moving stably. The telescopic spring 34 can play a buffering role to prevent the moving frame 2 from colliding with the fixed seat 1 too fast. At the same time, it can play a reset role. When the box is moved away, the telescopic spring 34 pushes the moving frame 2 to reset and wait for the next side guard.

[0045] Preferably, an installation groove 11 is provided at one end of the fixing seat 1 close to the second bracket 23 , and one end of the telescopic spring 34 close to the fixing seat 1 is arranged in the installation groove 11 .

[0046] With this structure, the installation groove 11 can play a role in positioning the telescopic spring 34, making installation easier.

[0047] Preferably, two groups of the movable guide mechanisms 3 are provided, and the two groups of the movable guide mechanisms 3 are arranged at intervals along the height direction of the fixing seat 1 .

[0048] By adopting this structure and arranging two groups of moving guide mechanisms 3 , the moving frame 2 can be ensured to move smoothly in the vertical height direction, thereby improving the moving stability of the moving frame 2 .
