[0069] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0070] Example 1

[0071] An embodiment of the present application provides an axial grooving device for a non-indentation paper tube, which helps improve the axial grooving efficiency and accuracy of the non-indentation paper tube.

[0072] Figure 1 This is a schematic diagram of the structure of the axial slotting device for the non-indented paper tube of this application, which will be referred to below Figure 1 The axial grooving device for the non-indentation paper tube of the present application is described in detail:

[0073] An axial grooving device for a non-indentation paper tube, comprising:

[0074] A main bracket 2, with a paper tube feeding mechanism 5, a groove milling mechanism 1 and a paper tube unloading mechanism 4 fixedly connected to the main bracket 2 sequentially arranged on either side of the main bracket 2 along the extension direction of the main bracket 2, and a paper tube clamping mobile platform 3 provided on the main bracket 2;

[0075] Among them, the paper tube feeding mechanism 5 is used to supply the paper tubes to be slotted to the paper tube clamping mobile platform 3 one by one; the paper tube clamping mobile platform 3 is used to clamp the paper tube to be slotted and then move toward the paper tube unloading mechanism 4; the milling mechanism 1 is used to slot the paper tube clamped by the paper tube clamping mobile platform 3 during the movement of the paper tube clamping mobile platform 3; the paper tube unloading mechanism 4 is used to unload the grooved paper tubes without indentation from the paper tube clamping mobile platform 3 one by one.

[0076] See Figure 2-3 The slot milling mechanism 1 includes: a slot washing frame 11; a milling cutter 12, which is a lotus cutter; a driving mechanism 15, which is arranged on the slot washing frame 11 and is used to drive the milling cutter 12 to rotate; an angle adjustment structure 13, which is arranged on the slot washing frame 11 and is used to adjust the elevation angle of the milling cutter 12; and a lifting mechanism 14, which is arranged on the slot washing frame 11 and is used to adjust the height of the milling cutter 12.

[0077] It is understandable that the actual structures of the driving mechanism 15, the angle adjustment structure 13 and the lifting mechanism 14 are not limited to being implemented using motors, slide rails and the like.

[0078] See Figure 4-6 The main support 2 includes a main frame 21, on which a pair of slotted rails 22 and a toothed chain 25 are provided along the extension direction of the main frame 21. A limit seat 23 is provided at each end of the slotted rail 22, and a limit member 24 is provided on the limit seat 23. Safety gratings 26 are also provided at each end of the slotted rail 22.

[0079] See Figure 7-8 , the paper tube clamping mobile platform 3 includes:

[0080] The first plate 31 has a slide 311 adapted to the slotted slide rail 22 provided below the first plate 31, and a first servo motor 33 is provided on the first plate 31 to cooperate with the toothed chain 25 to control the first plate 31 to slide on the slotted slide rail 22; the first plate 31 is also provided with a second slide rail 310 whose extension direction is perpendicular to the extension direction of the slotted slide rail 22, and the second plate 32 is slidably connected to the second slide rail 310, and the first plate 31 is provided with a second servo motor 34 to control the second plate 32 to slide on the second slide rail 310; the second plate 32 is fixedly connected to the third plate 35, and a plurality of L-shaped columns 36 are arranged on the third plate 35 at intervals along the extension direction, a cylinder 37 is provided on one end of the L-shaped column 36, and the cylinder 37 is connected to the upper clamping plate 38, and the other end of the L-shaped column 36 is provided with a lower clamping plate 39 that cooperates with the upper clamping plate 38 to clamp the paper tube.

[0081] In this embodiment, the upper clamping plate 38 and the lower clamping plate 39 are arc-shaped, so that the clamping surfaces of the upper clamping plate 38 and the lower clamping plate 39 are in close contact with the paper tube.

[0082] It is understandable that after the upper clamping plate 38 and the lower clamping plate 39 clamp the paper tube, a slotted gap will be left.

[0083] In this embodiment, the L-shaped column 36 is detachably connected to the third plate 35, and the lower clamping plate 39 is detachably connected to the L-shaped column 36. When the length of the paper tube changes, the L-shaped column 36 and the lower clamping plate 39 can be added at any time to clamp paper tubes of different lengths.

[0084] See Figure 9 , the paper tube feeding mechanism 5 includes:

[0085] The loading rack 51 is provided with an upper guide plate 52 , one end of the upper guide plate 52 is close to the lower clamping plate 39 , and the other end of the upper guide plate 52 is away from the lower clamping plate 39 and is higher than the end close to the lower clamping plate 39 .

[0086] A manual feeding lift mechanism 54 is mounted on the feeding frame 51 and fixedly connected to the end of the upper guide plate 52 closest to the lower clamping plate 39. This mechanism adjusts the height difference between the ends of the upper guide plate 52, thereby adjusting the downward roll speed of the slotted paper tubes. The other end of the upper guide plate 52 is fixedly connected to the feeding frame via a feeding support rod 53.

[0087] The paper tube blocking assembly 55 is arranged at one end of the upper guide plate 52 near the lower clamping plate 39, and includes an induction tube opening, a cylinder and a baffle connected to the cylinder. When the induction switch senses the paper tube to be slotted, the paper tube to be slotted is rolled to the lower clamping plate 39, and the cylinder is controlled to erect the baffle to block the subsequent paper tubes to be slotted.

[0088] The paper tube limiting plate 56 is provided on one side of the upper material guide plate 52 to prevent the paper tube to be slotted from rolling out of the upper material guide plate 52 .

[0089] See Figure 10 , the paper tube feeding mechanism 4 includes:

[0090] A lower material guide plate 42 is provided on the material unloading rack 41 , wherein one end of the lower material guide plate 42 is close to the lower clamping plate 39 , and the other end of the lower material guide plate 42 is away from the lower clamping plate 39 and is lower in height than the end close to the lower clamping plate 39 .

[0091] A manual lifting mechanism 44 for unloading paper is mounted on the unloading frame 41 and is fixedly connected to the end of the lower guide plate 42 near the lower clamping plate 39. This mechanism is used to manually adjust the height difference between the two ends of the lower guide plate 42, thereby adjusting the downward rolling speed of the paper tube to be slotted. The other end of the lower guide plate 42 is fixedly connected to the unloading frame 41 via a unloading support rod 43.

[0092] The paper tube blocking assembly 45 is arranged at one end of the lower guide plate 42 close to the lower clamping plate 39 .

[0093] The working principle of the axial grooving device for non-indentation paper tubes of the present application will be described below:

[0094] When a paper tube to be slotted rolls toward the lower clamping plate 39 on the paper tube feeding mechanism 5 due to the height difference between the two ends of the upper guide plate 52, the paper tube blocking assembly 55 blocks the paper tube to be slotted behind, and then the cylinder 37 on the paper tube clamping moving platform 3 controls the upper clamping plate 38 to clamp downward and cooperate with the lower clamping plate 39 to clamp the paper tube to be slotted, and then the second servo motor 34 controls the second plate 32 to slide on the second slide rail 310, that is, to control the slotting accuracy of the paper tube to be slotted. When the second plate 32 slides to the slotting accuracy position on the second slide rail 310, the rotation of the first servo motor 33 on the tooth chain 25 causes the first plate 31 to slide on the slotting slide rail 22, and is slotted by the milling cutter 12 of the milling mechanism 1 during the sliding process. When the paper tube clamping moving platform 3 moves to the paper tube unloading mechanism 4, the cylinder 37 is released to allow the slotted paper tube without indentation to roll down along the lower guide plate 42 of the paper tube unloading mechanism 4, and so on and so forth for slotting.

[0095] Example 2

[0096] One embodiment of the present application provides a method for axially grooving a non-indentation paper tube, and the axially grooving device for non-indentation paper tubes as described above is used to groove paper tubes of different batches and specifications.

[0097] Figure 11 This is a flow chart of the axial grooving method of the non-indentation paper tube of the present application, which will be referred to below Figure 11 The axial grooving method of the non-indentation paper tube of the present application is described in detail:

[0098] S101: Determining the corresponding equipment parameters of the axial slotting equipment based on characteristic information of the paper tube to be slotted;

[0099] It can be understood that the characteristic information of paper tubes in the same batch is consistent, so it is only necessary to determine the equipment parameters once for the same batch of paper tubes. When different batches of paper tubes need to be grooved, the equipment parameters need to be re-determined.

[0100] See Figure 12 , the specific steps include:

[0101] S201: Based on the length of the paper tube to be slotted, the number of lower clamping plates and L-shaped columns required is determined, and the calculation formula is as follows:

[0102]

[0103] Wherein, L is the length of the paper tube to be slotted, m is the length of the lower plywood, N is the number of lower plywood and L-shaped columns required, and n is the redundant number of lower plywood;

[0104] It should be noted that the redundant number refers to the additional number of lower clamps when the paper tube can be clamped, and its purpose is to make the clamping effect better and the grooving accuracy higher.

[0105] S202: Determining the slopes of the paper tube loading mechanism and the paper tube unloading mechanism based on the outer diameter of the paper tube to be slotted;

[0106] It is understandable that the slope affects the loading and unloading speeds of the paper tubes to be slotted.

[0107] S203: Based on the outer diameter of the paper tube to be slotted, the tube thickness, and the material to be wound, the corresponding first slotting parameters are determined using the following formula:

[0108] Y(k,a,c)=(V(k,a),U(a,c));

[0109] Wherein, Y(k, a, c) represents the first milling parameters, V(k, a) represents the lotus knife corresponding to the outer diameter k of the paper tube to be slotted and the tube thickness a, and U(a, c) represents the slotting depth corresponding to the tube thickness a and the material to be wound c;

[0110] In this embodiment, the relationship between the thickness a of the correction tube and the groove depth U corresponding to the material c to be wound is recorded in real time according to production requirements and production results to ensure that the groove depth is reasonable.

[0111] S204: Based on the first milling parameters and the outer diameter of the paper tube to be slotted, the corresponding second milling parameters are determined using the following formula:

[0112] Z(V,U,k)=(D(V,U),H(k));

[0113] D(V, U)=D0-V d +U+g;

[0114] H(k)=S+k / 2+e;

[0115] Among them, Z(V, U, c) is the second milling slot parameter, D(V, U) is the moving distance of the second plate in the paper tube clamping mobile platform, D0 is the initial distance between the second plate of the paper tube clamping mobile platform and the axis of the lotus knife, V d is the distance between the blade of the lotus knife V and the axis of the lotus knife, g is the equipment loss compensation length, H(k) is the height of the lotus knife, S is the initial height, and e is the equipment loss compensation height.

[0116] It should be noted that the equipment loss compensation length and equipment loss compensation height are measured and updated periodically based on the actual conditions of the equipment.

[0117] S102: After setting the equipment parameters, slotting the paper tube to be slotted;

[0118] According to the determined equipment parameters, the slotting equipment is adjusted and then slotting production begins.
