[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] Example

[0030] like Figure 1 As shown,Figure 1 Fig. 1 shows a schematic view of the packaging device in the embodiment.

[0031] The device comprises a frame 10 and a conveying roller 20, the conveying roller 20 comprising a mounting frame and a roller body rotatably arranged on the upper end of the mounting frame, a pressing assembly arranged on the inner top wall of the frame 10, the pressing assembly comprising a hydraulic cylinder 52 and a pressing piece 51 connected to the output end of the hydraulic cylinder 52.

[0032] The pressing assembly presses the cover extension of the packaging box 1 conveyed on the conveying roller 20 to be attached to the box body, and the hydraulic cylinder 52 serves as a driving function to drive the pressing piece 51 to move up and down to complete the pressing action.

[0033] As shown in Figure 1 , Figure 2 , Figure 1 Fig. 1 shows a schematic view of the packaging device in the embodiment, Figure 2 Fig. 2 shows a schematic view of the packaging device in the embodiment.

[0034] The device further comprises a positioning assembly 30, which positions and fixes the packaging box 1 conveyed on the conveying roller 20, so as to facilitate the pressing assembly to accurately press the packaging box 1.

[0035] The positioning assembly 30 serves to stop and push the packaging box 1 conveyed on the conveying roller 20 to a position below the corresponding pressing assembly, so as to facilitate the pressing assembly to accurately press the packaging box 1.

[0036] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 1 Fig. 1 shows a schematic view of the packaging device in the embodiment, Figure 2 Fig. 2 shows a schematic view of the packaging device in the embodiment, Figure 3 Fig. 3 shows a schematic view of the positioning assembly in the embodiment.

[0037] The positioning assembly 30 comprises a mounting plate, and a threaded rod one 31 is symmetrically arranged inside the mounting plate, the threaded rod one 31 being rotatably connected to the mounting plate, and a same push plate 32 being threadedly sleeved on the two threaded rod ones 31, the push plate 32 comprising two connection column bodies threadedly sleeved on the threaded rod ones 31 at two ends, and rod bodies vertically and spaced apart arranged on the upper end of the connection column bodies, each rod body extending from the space between adjacent roller bodies to above the roller bodies and to a side of the packaging box 1 away from the pressing assembly.

[0038] The positioning assembly 30 further comprises a driving piece arranged on the mounting plate at an end of the threaded rod one 31 away from the packaging box 1, the driving piece driving the threaded rod one 31 to rotate, thereby driving the push plate 32 to push the packaging box 1 conveyed toward a side where the pressing assembly is located.

[0039] The limiting strip is arranged on the side of the conveying roller 20 close to the pressing assembly. When the driving member pushes the packaging box 1, the packaging box 1 stops when it abuts against the limiting strip. At this time, the pressing assembly presses the packaging box 1 below.

[0040] As shown in Figure 2 , Figure 3 , Figure 2 Fig. 2 shows a top view of the packaging device in the embodiment, Figure 3 Fig. 3 shows a top view of the positioning assembly in the embodiment.

[0041] The driving member comprises a motor 381 and a bevel gear one 382. The motor 381 and the bevel gear one 382 are arranged on the outer side wall of the end of the mounting plate away from the packaging box 1. The bevel gear one 382 is connected with one end of the threaded rod one 31. The output end of the motor 381 is connected with a gear one. The gear one is connected with a gear two in a meshing mode. The gear two is fixedly provided with a shaft. The two ends of the shaft are provided with bevel gears two 383. The bevel gears two 383 are connected with the bevel gear one 382 in a perpendicular meshing mode.

[0042] As shown in Figure 2 , Figure 3 , Figure 4 , Figure 2 Fig. 2 shows a top view of the packaging device in the embodiment, Figure 3 Fig. 3 shows a top view of the positioning assembly in the embodiment, Figure 4 Fig. 4 shows a front view of the baffle in the embodiment.

[0043] The baffle 37 is movably arranged between the adjacent roller bodies at the most front end in the conveying direction of the packaging box 1. The baffle 37 blocks the most front end of the packaging box 1 when the packaging box 1 is conveyed, so that the conveying of the packaging box 1 is stopped. The end of the baffle 37 close to the packaging box 1 is further provided with a gravity sensor 39. The output end of the gravity sensor 39 is connected with the driving end of the control roller body in a signal mode.

[0044] The baffle 37 is initially in a state of extending to a position higher than the roller body. When the packaging box 1 conveyed on the conveying roller 20 contacts the baffle 37, the packaging box 1 stops advancing. At the same time, the gravity sensor 39 of the baffle 37 senses the pressure, and the signal is transmitted to the driving end of the control roller body, so that the roller body stops rotating. Then, the push plate 32 pushes the packaging box 1 in the stopped state towards the side where the pressing assembly is located, so that the packaging is performed.

[0045] As shown in Figure 3 , Figure 4 , Figure 5 , Figure 3 Fig. 3 shows a top view of the positioning assembly in the embodiment, Figure 4The diagram shown is a front view of the baffle in the embodiment. Figure 5 The diagram shows different states of the connection between the rack and the push plate in the embodiment.

[0046] A rack 33 is provided at the end of the connecting column on the push plate 32 away from the feeding side of the conveying roller 20. The rack 33 is set in a sliding groove opened on the mounting plate, and both ends of the rack 33 are connected to the mounting plate by spring 34. A connecting groove is opened at the end of the rack 33 near the threaded rod 31. The connecting column is movably connected to the rack 33 through the connecting block 331 set at the connecting end, and a slot 332 is opened at the end of the connecting groove away from the baffle 37.

[0047] A gear 35 is provided at one end of the rack 33 away from the threaded rod 31. A threaded rod 36 is vertically arranged in the gear 35, and a baffle 37 is threaded onto the surface of the threaded rod 36.

[0048] During the process of the drive unit driving the threaded rod 31 to rotate and the push plate 32 to move towards the packaging box 1, the connecting block 331 set on the connecting column of the push plate 32 slides in the connecting groove of the rack 33. At this time, the baffle 37 remains in a state of extending above the roller. When the drive unit drives the threaded rod 31 to rotate in the opposite direction, that is, during the process of retracting the push plate 32 after packaging, the connecting block 331 will slide into the slot 332 of the connecting groove. At this time, the spring 34 will deform, but the force generated by the deformation of the spring 34 on the rack 33 is not enough to pull the connecting block 331 out of the slot 332. Therefore, at this time, the push plate 32 continues to move away from the packaging box 1 and drives the rack 33 to move to that side. The movement of the rack 33 drives the gear 35 meshing with the rack 33 to rotate, thereby driving the threaded rod 36 to rotate. Finally, the baffle 37 descends to below the roller. At this time, the pressure sensed by the gravity sensor 39 set on the baffle 37 disappears, the roller rotates again, thereby driving the packaged packaging box 1 to continue to be transported.

[0049] When the connecting block 331 enters the slot 332 and drives the rack 33 to move a certain distance, the force borne by the spring 34 will increase, causing the connecting block 331 to disengage from the slot 332 and drive the rack 33 to return to its original position. At this time, the baffle 37 returns to its initial state, that is, the state above the roller body, and continues to stop the next package box 1 that is conveyed.

[0050] like Figure 5 , Figure 6 As shown, the connecting block 331 includes a block body 3311 and movable heads 3313 symmetrically and movably disposed at the upper and lower ends of the block body 3311. The movable heads 3313 are connected to the block body 3311 via spring 3312. The movable heads 3313 are elastic components.

[0051] When the connecting block 331 moves in the connecting groove, the force of the spring 3312 on the movable head 3313 is small, so the rack 33 cannot be moved.

[0052] When the connecting block 331 enters the clamping groove 332, the spring 3312 is deformed to drive the movable head 3313 into the clamping groove 332, at this time, the rack 33 can be moved a distance, and at this time, the baffle 37 is in a state of being lower than the roller body. When continuing to move, the force of the spring 34 on the rack 33 will be greater than the force of the spring 3312 on the movable head 3313, that is, the movable head 3313 is pulled out of the clamping groove 332, and the baffle 37 returns to the initial state.

[0053] As shown in Figure 1 , Figure 7 , Figure 1 Fig. 1 shows a front view of the packaging device in the embodiment; Figure 7 Fig. 2 shows a schematic view of the lower pressing piece in the embodiment.

[0054] Further comprising a pressing plate 41 and a cylinder 42, the cylinder 42 is arranged on the inner top wall of the frame body 10 corresponding to the position above the packaging box 1, and the cylinder 42 drives the pressing plate 41 to ascend and descend to fix the position of the packaging box 1.

[0055] The lower pressing piece 51 further comprises a pressing roller 511 arranged at one end close to the packaging box 1.

[0056] After the baffle 37 stops the packaging box 1 and the push plate 32 positions the packaging box 1, the cylinder 42 is opened to drive the pressing plate 41 to descend and further fix the position of the packaging box 1 by pressing the upper end of the packaging box 1, so as to avoid displacement of the packaging box 1 when the lower pressing piece 51 presses the packaging box 1, thereby avoiding errors.

[0057] The lower pressing piece 51 provided with the pressing roller 511 reduces the friction force when pressing and bending the cover extension of the packaging box 1, thereby avoiding damage to the packaging box 1.

[0058] Working principle: when the device packs the packaging box 1 containing furniture parts, first, the baffle 37 stops the packaging box 1 conveyed by the feeding end of the conveying roller 20, then the driving part is opened, and drives the threaded rod one 31 to rotate, thereby driving the push plate 32 to push the conveyed packaging box 1 towards the side where the lower pressing assembly is located until it stops when it abuts against the limiting strip, then the cylinder 42 is opened to drive the pressing plate 41 to descend and further fix the position of the packaging box 1, then the hydraulic cylinder 52 is opened to drive the lower pressing part 51 to move downwards to bend and press the cover extension of the packaging box 1 to the box body to complete the packing, after the packing is completed, the driving part is opened in reverse, and the threaded rod one 31 is reversely rotated, at this time, the connecting block 331 provided on the connecting column of the push plate 32 slides in the connecting groove of the rack 33, at this time, the baffle 37 is extended to a state higher than the roller body, when the connecting block 331 slides into the clamping groove 332 of the connecting groove, at this time, the spring one 34 is deformed, but the force generated by the spring one 34 to the rack 33 is not enough to pull the connecting block 331 out of the clamping groove 332, therefore, at this time, the push plate 32 continues to move away from the packaging box 1, and at the same time, the rack 33 also moves to the side, the movement of the rack 33 drives the gear one 35 engaged with the rack 33 to rotate, thereby driving the threaded rod two 36 to rotate, finally, the baffle 37 is lowered to below the roller body, at this time, the pressure sensed by the gravity sensor 39 provided on the baffle 37 disappears, the roller body rotates again, thereby conveying the packed packaging box 1 away, when the connecting block 331 enters the clamping groove 332 and drives the rack 33 to move a distance, because the force borne by the spring one 34 is getting larger and larger, the connecting block 331 will be separated from the clamping groove 332, and the rack 33 will return to the original position, at this time, the baffle 37 also returns to the initial state, that is, the state of being higher than the roller body, and the next conveyed packaging box 1 is stopped.

[0059] The above examples are only used to illustrate the technical solutions of the present application, but not limit it.
