DETAILED DESCRIPTION

[0034] The content of the utility model will be further explained in detail in combination with specific embodiments:

[0035] A kind of pressure groove line equipment for paperboard, by rolling make and form groove line on the paperboard 100 of flat, to facilitate paperboard 100 in subsequent process can be folded along groove line and form three-dimensional packaging box.

[0036] As Figure 1 As shown, including base 2, driving device 3 is arranged on base 2, paperboard 100 is driven under driving device 3 and moves linearly on base 2 along first direction.Base 2 is fixed with gantry support 6, and pressure groove device 4 is connected to gantry support 6. Figure 2 As shown, pressure groove device 4 includes body 42 and pressure groove piece 41 connected to body 42.Body 42 is arranged on gantry support 6, and the gap between the end of pressure groove piece 41 close to base 2 and base 2 has gap, and forms passageway for paperboard 100, the height of passageway is less than the thickness of paperboard 100, so that when paperboard 100 is driven under driving device 3 and passes through the passageway, pressure groove piece 41 and paperboard 100 abut on paperboard 100, and groove line is pressed out on paperboard 100 along with the movement of paperboard 100.

[0037] As Figure 3As shown, in the present embodiment, the driving device 3 adopts a conveying line mechanism 3a, which comprises conveying rollers 31a arranged at both ends of the base 2 along the first direction, and a conveying belt 32a drivingly connected to the conveying rollers 31a, and the paperboard 100 is loaded on the conveying belt 32a. The conveying rollers 31a rotate around their own axes under the driving of the motor, and drive the conveying belt 32a to move along the first direction.

[0038] In other embodiments of the present application, as shown, the driving device 3 can also adopt a clamping driving mechanism 3b, which comprises clamps 31b slidingly arranged at both sides of the base 2, the clamps 31b clamping both sides of the paperboard 100 and driving the paperboard 100 to move along the first direction under the driving of the cylinder 32b. Figure 4

[0039] A flow channel adjusting device 5 is arranged at both sides of the base 2, and the flow channel adjusting device 5 slidingly abuts against both ends of the paperboard 100 parallel to the first direction, so that the paperboard 100 can only be conveyed along the first direction in close contact with the flow channel adjusting device 5, and the paperboard 100 is prevented from being skewed and misaligned during the pressing groove operation. In addition, in order to be compatible with paperboards 100 of different size specifications, the flow channel adjusting device 5 can be opened and closed. Specifically, the flow channel adjusting device 5 comprises an adjusting bracket 51 fixed to the base 2, and the adjusting bracket 51 is similar in structure to the gantry bracket 6. A pair of flow channel edges 52 are arranged on the adjusting bracket 51, and any flow channel edge 52 has a length direction parallel to the first direction. The flow channel edges 52 can slide along the adjusting bracket 51 along a second direction perpendicular to the first direction, so that the distance between the pair of flow channel edges 52 changes, thereby adapting to paperboards 100 of different widths.

[0040] In the preferred embodiments of the present application, in order to be able to perform the pressing groove operation on paperboards 100 of different thicknesses, the pressing groove piece 41 is provided with an adaptive mechanism 43 at the end away from the base 2. The adaptive mechanism 43 can give the pressing groove piece 41 a force towards the base 2, and enable the pressing groove piece 41 to change the distance from the base 2.

[0041] The adaptive mechanism 43 has various forms of construction. In the embodiments of the present application, the adaptive mechanism 43 adopts an elastic mechanism 43a. As shown, Figure 2 The elastic mechanism 43a comprises an elastic piece 431a, and the two ends of the elastic piece 431a are respectively connected with a first connecting block 432a and a second connecting block 433a, and the first connecting block 432a and the second connecting block 433a are respectively connected with the pressing groove piece 41 and the body 42. The arrangement of the elastic piece 431a enables the pressing groove piece 41 to move up and down while always maintaining a pressing force towards the base 2. In addition, the body 42 is provided with a guide mechanism matched with the first connecting block 432a, so that the first connecting block 432a can move along a predetermined path. ​

[0042] The elastic element 431a also has two configuration methods, including using, for example Figure 2 The spring 431a1 shown extends and retracts along its own length to release elastic force, and as shown in the figure Figure 5 The rubber rod 431a2 shown is released by bending.

[0043] In this application, as Figure 2 As shown, the elastic element 431a is constructed as a spring 431a1, which is arranged vertically. When the cardboard 100 abuts against the grooved member 41, the spring 431a1 connected to the grooved member 41 will rise to a corresponding height according to the thickness of the paper 100, causing the first connecting block 432a and the grooved member 41 to lift upwards and move toward the second connecting block 433a. At the same time, the elastic force stored in the spring 431a1 will also cause the grooved member 41 to apply pressure to the abutting cardboard 100, thereby groove-pressing.

[0044] In this configuration, the guiding mechanism is constructed as a first guiding mechanism 44a1. The first guiding mechanism 44a1 includes a guide block 441a1 fixed to the body 42. A first guide groove is vertically formed at the end of the guide block 441a1 away from the body 42. A guide rail is configured at the middle of the first connecting block 432a, and the guide rail slides in conjunction with the first guide groove. When the pressing member 41 is subjected to the force of the cardboard 100, the spring 431a1 is compressed, allowing the first connecting block 432a to move vertically up and down along the first guide groove, thereby enabling the pressing member 41 to move upwards.

[0045] like Figure 5 As shown, when the elastic element 431a is a rubber rod 431a2, the rubber rod 431a2 is set horizontally or inclined. When the cardboard 100 abuts against the groove pressing element 41, the end of the rubber rod 431a2 near the first connecting block 432a will be raised to a corresponding height according to the thickness of the cardboard 100. Since the other end of the rubber rod 431a2 is fixed to the second connecting block 433a, this will cause the rubber rod 431a2 itself to bend, thereby storing elastic force. The stored elastic force will also cause the groove pressing element 41 to apply pressure to the abutting cardboard 100, thereby performing groove pressing.

[0046] In this arrangement, the guide mechanism is configured as a second guide mechanism 44a2, which includes a guide plate 441a2 fixed to the body 42, and an arc-shaped second guide slot 442a2 is formed in the guide plate 441a2, with the opening end of the arc-shaped structure of the second guide slot 442a2 facing the second connecting block 433a. The side of the first connecting block 432a close to the guide plate 441a2 is fixed with a buckle that is in sliding cooperation with the guide slot. When the pressure groove piece 41 is subjected to the force of the paperboard 100, the rubber rod 431a2 bends, causing the first connecting block 432a to move along the second guide slot 442a2, so that the pressure groove piece 41 can move upward along an arc-shaped path.

[0047] In this embodiment, the rubber rod 431a2 can also be replaced by a torsion spring or other device that stores energy by bending.

[0048] As Figure 6 shown, in other embodiments of the present application, the adaptive mechanism 43 adopts a magnetic force mechanism 43b, which includes a pair of first and second magnetic blocks 431b and 432b that are magnetically repulsive, the first and second magnetic blocks 431b and 432b are arranged in the vertical direction and are respectively fixed to the pressure groove piece 41 and the body 42, and the second magnetic block 432b applies a repulsive force to the first magnetic block 431b communicated through the pressure groove piece 41 towards the paperboard 100. A guide cylinder 433b is arranged in cooperation with the first magnetic block 431b, the guide cylinder 433b is hollow inside, the first magnetic block 431b is coaxially arranged in the guide cylinder 433b and slides along the axis of the guide cylinder 433b. When the pressure groove piece 41 abuts against the paperboard 100, the first magnetic block 431b connected with the pressure groove piece 41 will be lifted by a corresponding height in the guide cylinder 433b according to the thickness of the paperboard 100, i.e. moving towards the second magnetic block 432b. This will simultaneously cause the repulsive force between the first and second magnetic blocks 431b and 432b to increase, thereby exerting a force on the pressure groove piece 41 connected with the first magnetic block 431b towards the paperboard 100, and further performing the pressure grooving.

[0049] As Figure 7As shown, the pressure groove device 4 further comprises a lifting mechanism 44 for lifting and fixing part or all of the pressure groove pieces 41 in the plurality of pressure groove devices 4 from the base 2, so as to change the number of groove lines pressed on the paperboard 100. The lifting mechanism 44 comprises a lifting rod 441 and a lifting handle 442. Taking the embodiment in which the elastic mechanism 43a is used as the adaptive mechanism 43 as an example, the lifting rod 441 penetrates through the second connecting block 433a and is fixed with the first connecting block 432a. The lifting handle 442 is provided in an L-shaped structure, having a long side 4421 and a short side 4422, as well as a middle part 4423 bent at 90°. The long side 4421 serves as a holding end, the short side 4422 is hinged with one end of the lifting rod 441, and the middle part 4423 is hinged with a connecting rod 4424, one end of the connecting rod 4424 away from the middle part 4423 being hinged with the second connecting block 433a.

[0050] In this way, by pulling the long side 4421, the lifting rod 441 moves with the long side 4421 and overcomes the force of the adaptive mechanism 43 to perform lifting movement under the action of the connecting rod mechanism formed by the short side 4422 and the connecting rod 4424. The lifted pressure groove piece 41 is fixed under the self-locking action of the connecting rod mechanism formed by the short side 4422 and the connecting rod 4424.

[0051] The pressure groove device 4 in the present application is provided in plurality on the same gantry support 6. In order to enable the paperboard 100 to press groove lines with different intervals, the pressure groove device 4 is connected with the gantry support 6 in sliding connection. Specifically, as shown, Figure 2 The body 42 is fixed with a clamping block 45 at one end away from the adaptive mechanism 43, the clamping block 45 is provided with a through hole horizontally, and the clamping block 45 is sleeved on the gantry support 6 through the through hole, so that the clamping block 45 can slide on the gantry support 6. In addition, the clamping block 45 is provided with a fastening hole vertically, and a fastener 451 is fitted in the fastening hole, the fastener 451 is in abutment with the gantry support 6 after penetrating through the fastening hole, so that the pressure groove device 4 is locked at a preset position. In addition, in the present embodiment, the clamping block 45 is provided in two in the vertical direction in any pressure groove device 4, and is fastened with two horizontal rods arranged in parallel on the gantry support 6, so as to avoid the swinging of the pressure groove device 4 around the gantry support 6 caused by the arrangement of a single clamping block 45.

[0052] In the preferred embodiment of the present application, the pressure groove piece 41 is configured as a roller, and a mounting groove is vertically provided at one end of the first connecting block 432a close to the base 2, and the roller is installed in the mounting groove in a state that the axis is horizontal. The roller is in abutment with the paperboard 100 under the action of the adaptive mechanism 43, and rolls along the surface of the paperboard 100 under the action of the conveying belt 32a, so as to form groove lines on the paperboard 100.

[0053] When working:

[0054] Step one, the operator puts the paperboard 100 into the entrance end of the base 2.

[0055] Step two, adjust the pair of flow channel stop edges 52 in the flow channel adjusting device 5, so that the pair of flow channel stop edges 52 abut the two sides of the paperboard 100 in the first direction. Adjust the position of the pressure groove device 4 on the gantry bracket 6, so that it corresponds to the preset pressure groove position on the paperboard 100, then lock the pressure groove device 4 at the current position of the gantry bracket 6, and pull down the lifting mechanism 44 to lower the pressure groove piece 41 to the height that can abut the paperboard 100.

[0056] Step three, start the driving device 3, so that the paperboard 100 is conveyed along the first direction and abuts the pressure groove piece 41 to perform the pressure groove operation.
