Description

Technical Field

[0001] This utility model relates to the technical field of hygiene product processing equipment, specifically to a belt material corner conveyor device for the hygiene product industry. Background Technology

[0002] Currently in the hygiene products industry, the final product needs to go through multiple processes. When transferring between processes, the material is usually rotated and rolled into a disc shape for easy use in the next process. For example, in the existing roll material slitting process, the rolled material needs to be slit into several strips and then rolled up for the next process. The slitting process can be divided into one-to-two and one-to-many.

[0003] In the roll slitting process, the roll is cut into multiple strips of material. When the multiple strips of material are wound up, they need to be wound up synchronously. In some existing winding equipment, winding devices arranged in a straight line are usually used to wind up multiple strips of material simultaneously. Each strip of material corresponds to a winding roller in a single winding device.

[0004] In the application document with publication (announcement) number CN110054834A, a core winding and rewinding unit for the hygiene products industry is disclosed. The winding and rewinding unit in this application document is arranged in a straight line, and the unwinding and slitting device is set at the end of the winding unit and directly faces the winding and rewinding unit in a straight line for unwinding and slitting. The strip material is conveyed one by one from above the winding and rewinding unit to the corresponding winding and rewinding unit. However, in the actual use process, the following problems still exist.

[0005] 1. Equipment footprint issue: When the width of the material roll to be slit is greater than the width of the winding device, the entire slitting and winding equipment will be arranged in a T-shape. As the width of the material roll increases, the overall width of the equipment will be larger, resulting in lower site area utilization. 2. Material unwinding issue: After slitting, the strip material near both ends of the wider material roll needs to be aligned towards the center of the material roll by the alignment rollers before it can be conveyed directly above the winding unit. However, different widths of rolls result in different widths of strip material and different numbers of strip materials cut. After changing materials, the offset angle of each alignment roller needs to be readjusted for realignment, which is quite troublesome. Utility Model Content

[0006] To address the technical deficiencies in the background art, this utility model proposes a corner conveying device for strip materials in the hygiene products industry, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0007] A belt material corner conveying device for the hygiene products industry includes a main body of equipment. The main body of equipment is provided with a corner conveying structure along the X-axis. The corner conveying structure includes a lifting mechanism, a corner mechanism and a correction mechanism. The corner mechanism is movably arranged along the length direction of the correction mechanism. The correction mechanism extends along the Y-axis and has at least one movable base and a screw structure for adjusting the movable base to move along the Y-axis.

[0008] The cornering mechanism has a cornering roller and a first conveying roller. The cornering roller is aligned with the bisector of the angle between the X-axis and the Y-axis, and the first conveying roller is at a right angle to the Y-axis.

[0009] As an improvement to the above solution, the number of the corner conveying structures is two, and they are staggered along the X-axis and Y-axis directions, respectively.

[0010] As an improvement to the above solution, the lifting mechanism includes several lifting rollers arranged layer by layer along the Z-axis direction, with adjacent lifting rollers arranged at equal intervals, and a pressure roller is provided at the upper working position of the lifting roller.

[0011] As an improvement to the above solution, the correction mechanism comprises a first fixed bracket and a second fixed bracket arranged vertically along the Z-axis, and several layers of correction structures disposed between the first fixed bracket and the second fixed bracket.

[0012] The correction structure is arranged layer by layer along the Z-axis, with adjacent sets of correction structures arranged at equal intervals. The corner mechanism is arranged layer by layer in a staggered manner on the correction structure along the Y-axis.

[0013] As an improvement to the above solution, the correction structure includes a guide rod and a lead screw structure that horizontally connect the first fixed bracket and the second fixed bracket along the Y-axis direction, and a first movable base and a second movable base passing through the guide rod and the lead screw structure.

[0014] The corner roller and the first conveying roller are respectively mounted on the first movable base and the second movable base.

[0015] As an improvement to the above solution, the lead screw structure includes an adjusting lead screw and an adjusting handle. One end of the adjusting lead screw passes through the first fixed bracket and is connected to the adjusting handle, while the other end is hinged to the second fixed bracket. The adjusting lead screw passes horizontally through the second movable base along the Y-axis direction. A rotary encoder is provided on the outer surface of the first fixed bracket corresponding to the position where the adjusting lead screw passes through.

[0016] As an improvement to the above solution, the guide rod is symmetrically arranged on both sides of the adjusting screw, and its ends are respectively fixed to the first fixed bracket and the second fixed bracket. The guide rod passes horizontally through the first movable base and the second movable base along the Y-axis direction.

[0017] As an improvement to the above solution, the corner mechanism includes a corner roller, a first conveying roller, and a third movable base disposed on the end face of the first movable base. The third movable base is aligned with the first conveying roller along the Y-axis direction, and the bottom of the third movable base is hinged to the first movable base.

[0018] As an improvement to the above solution, the second movable base is provided with a vertical connecting part at the positions corresponding to the two ends of the first conveying roller. The two ends of the first conveying roller are hinged to the vertical connecting part. A gap is reserved between the bottom of the first conveying roller and the second movable base. The two ends of the third movable base are clamped upwards in a clamping shape at the two ends of the corner roller. A gap is reserved between the bottom of the corner roller and the third movable base.

[0019] As an improvement to the above solution, a conveying bracket is provided above the corner mechanism. The conveying bracket is provided with a plurality of second conveying rollers aligned with the Z-axis direction of the first conveying roller. The second conveying rollers are staggered layer by layer along the Y-axis direction.

[0020] The beneficial effects of this utility model are as follows: After the roll material is cut, several strip materials are formed and turned in the same X-axis coordinate through the corner conveyor structure. Before turning, the strip material forms interlayer separation along the Z-axis under the misalignment action of the lifting mechanism. After turning, the strip material is conveyed in a straight line along the Y-axis to the linearly arranged winding device. The corner conveyor device allows the material conveying direction of the unwinding device and the winding device to be set perpendicularly. The equipment can better handle the roll material with a larger width. There is no need to worry that the increase in the width of the unwinding device will affect the overall width of the equipment, thus improving the space utilization rate. In addition, when switching roll materials with different widths, there is no need to adjust the corner angle of the corner roller to achieve centering due to the different widths and numbers of strip materials, which simplifies the process.

Detailed Implementation

[0029] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0030] like Figure 1 As shown, a belt material corner conveying device for the hygiene products industry includes a main body 1. The main body 1 is provided with a corner conveying structure 2 along the X-axis. The corner conveying structure 2 includes a lifting mechanism 3, a corner mechanism 4, and a correction mechanism 5. The corner mechanism 4 is movably arranged along the length direction of the correction mechanism 5. The correction mechanism 5 extends along the Y-axis and has at least one movable base and a screw structure 54 for adjusting the movable base along the Y-axis.

[0031] like Figure 1As shown, in the technical solution of the corner conveyor structure 2 of this utility model, the unwinding direction of the strip material is the X-axis and the winding direction is the Y-axis. The corner conveyor structure 2 is applied between the slitting device and the winding device in the production line. The winding device is placed and wound along the Y-axis, and the unwinding device unwinds the material to the slitting device along the X-axis. In use, after the material passes through the unwinding device and the slitting device, it forms several strip materials that are conveyed in parallel. During the conveying process, the strip materials are lifted and turned by the corner conveyor structure 2. The conveying state changes from parallel conveying along the X-axis to layer-by-layer arrangement along the Z-axis and straight conveying along the Y-axis. The strip material at the top of the Z-axis is conveyed to the winding roller near the end of the winding device, and the strip material at the bottom of the Z-axis is conveyed to the winding roller near the front of the winding device.

[0032] It should be noted that during the unwinding process of the unwinding device, when the width of the material exceeds the width of a single corner conveyor structure 2, multiple corner conveyor structures 2 can be set up, and the X-axis and Y-axis coordinates of two adjacent corner conveyor structures can be staggered. The strip material exceeding the width of the first corner conveyor structure 2 can be conveyed across the corner conveyor structure 2 towards another corner conveyor structure 2. The corner conveyor structure 2 is used to lift and turn the extra-wide strip material.

[0033] like Figures 1 to 5 As shown, it should be noted that the two adjacent corner conveyor structures 2 are staggered along the X-axis and Y-axis directions, and the strip material is arranged side by side in the Y-axis direction. The staggered arrangement of the corner conveyor structure 2 can effectively deal with the problem of winding and turning a large number of strip materials formed after the wide roll material is cut.

[0034] In one specific embodiment, the winding device may be a double-sided winding device arranged in a straight line. The winding rollers on both sides of the double-sided winding device are staggered between two adjacent corner conveyor structures 2. The strip material of the extra-wide portion is lifted and turned by the second corner conveyor structure 2 and then wound on the other side of the double-sided winding device.

[0035] like Figures 2 to 6 As shown, in the technical solution of the corner conveying structure 2 of this utility model, the corner conveying structure 2 includes a lifting mechanism 3, a cornering mechanism 4 and a correction mechanism 5. The lifting mechanism 3 is used to lift the strip material to different Z-axis coordinates. The correction mechanism 5 is used to adjust the cornering mechanism 4 to align with the strip material. The cornering mechanism 4 is movably arranged along the length direction of the correction mechanism 5. The correction mechanism 5 extends along the Y-axis direction and has at least one movable base and a screw structure 54 for adjusting the movable base to move along the Y-axis direction.

[0036] like Figure 2 and Figure 3As shown, in the technical solution of the lifting mechanism 3 of this utility model, the lifting mechanism 3 includes a plurality of lifting rollers 31 arranged layer by layer along the Z-axis direction. Two adjacent lifting rollers 31 are arranged at equal intervals. A pressure roller 32 is provided at the upper working position of the lifting roller 31. The strip material formed after the roll material is cut passes under the pressure roller 32. The pressure roller 32 keeps the strip material on the same horizontal plane to avoid the phenomenon of up and down fluctuation during the conveying process due to local tension differences. After passing through the pressure roller 32, the strip material is neatly conveyed to the lifting roller 31. Each lifting roller 31 corresponds to a single strip material, lifting the strip material to different horizontal heights.

[0037] like Figure 4 and Figure 5 As shown, in the technical solution of the corner mechanism 4 of this utility model, the corner mechanism 4 has a corner roller 41 and a first conveying roller 42. The corner roller 41 is aligned with the bisector of the angle between the X-axis and the Y-axis. The first conveying roller 42 is at a right angle with the Y-axis. The corner roller 41 is offset towards the starting end of the conveying of the strip material. During conveying, the strip material passes under the corner roller 41 and is output above the corner roller 41, thereby realizing the turning of the strip material. The turned strip material is conveyed towards the first conveying roller 42, that is, the turning is conveyed along the Y-axis direction.

[0038] like Figure 4 and Figure 5 As shown, in the technical solution of the correction mechanism 5 of this utility model, the correction mechanism 5 comprises a first fixed bracket 51 and a second fixed bracket 52 arranged vertically along the Z-axis direction, and a plurality of layers of correction structures 53 arranged between the first fixed bracket 51 and the second fixed bracket 52.

[0039] The correction structure 53 is arranged layer by layer along the Z-axis, and adjacent sets of correction structures 53 are arranged at equal intervals. The corner mechanism 4 is arranged layer by layer staggered on the correction structure 53 along the Y-axis.

[0040] It should be noted that the correction mechanism 5 is used to adjust the coordinates of the corner mechanism 4 in the Y-axis direction so that the corner mechanism 4 is on the X-axis transmission path of the strip material, thereby realizing the turning of the strip material. The position of the correction structure 53 between layers corresponds to the Z-axis position of the lifted strip material.

[0041] Furthermore, in the technical solution of the correction structure 53, the correction structure 53 includes a guide rod 57 and a lead screw structure 54 that are horizontally connected to the first fixed bracket 51 and the second fixed bracket 52 along the Y-axis direction, and a first movable base 55 and a second movable base 56 that are passed through the guide rod 57 and the lead screw structure 54. The corner roller 41 and the first conveying roller 42 are respectively disposed on the first movable base 55 and the second movable base 56.

[0042] Furthermore, in the above scheme, the guide rod 57 is symmetrically arranged on both sides of the adjusting screw 541, and its ends are respectively fixed to the first fixed bracket 51 and the second fixed bracket 52. The guide rod 57 passes horizontally through the first movable base 55 and the second movable base 56 along the Y-axis direction.

[0043] It should be noted that the guide rod 57 structure guides the first movable base 55 and the second movable base 56. The Y-axis coordinate of the second movable base 56 can be adjusted by rotating the screw structure 54. The first conveying roller 42 is set on the second movable base 56. Adjusting the Y-axis coordinate of the second movable base 56 corresponds to adjusting the Y-axis coordinate of the first conveying roller 42. Adjusting the Y-axis coordinate of two adjacent first conveying rollers 42 corresponds to adjusting the interlayer spacing of the two adjacent strip materials after the turn.

[0044] In the technical solution of the lead screw structure 54 of this utility model, the lead screw structure 54 includes an adjusting lead screw 541 and an adjusting handle 542. One end of the adjusting lead screw 541 passes through the first fixed bracket 51 and is connected to the adjusting handle 542, and the other end is hinged to the second fixed bracket 52. The adjusting lead screw 541 passes horizontally through the second movable base 56 along the Y-axis direction. A rotary encoder 543 is provided on the outer surface of the first fixed bracket 51 corresponding to the position where the adjusting lead screw 541 passes through.

[0045] It should be noted that rotating the adjustment handle 542 drives the adjustment screw 541 to rotate, thereby driving the second movable base 56 to rotate along the Y-axis. The rotary encoder 543 is set at the drive end of the adjustment screw 541. By detecting the rotation angle of the screw, the position distance of the second movable base 56 is indirectly calculated, thereby accurately adjusting the position of the second movable base 56 in the layer-by-layer correction structure 53.

[0046] In the technical solution of the corner mechanism 4 of this utility model, the corner mechanism 4 includes a corner roller 41, a first conveying roller 42, and a third movable base 43 disposed on the end face of the first movable base 55. The third movable base 43 is aligned with the first conveying roller 42 along the Y-axis direction, and the bottom of the third movable base 43 is hinged to the first movable base 55.

[0047] The first conveying roller 42 moves with the second movable base 56, the corner roller 41 moves with the first movable base 55, the first movable base 55 is fixed on the guide rod 57, and the Y-axis coordinate of the first movable base 55 is aligned with the Y-axis coordinate of the conveying strip material.

[0048] The corner roller 41 is fixed on the third movable base 43, which is hinged to the first movable base 55. A locking element is provided between the third movable base 43 and the first movable base 55. The locking element is either a screw or a handle, which is inserted between the first movable base 55 and the third movable base 43. After adjusting the rotation angle of the third movable base 43, it locks the first movable base 55 and the third movable base 43.

[0049] It should be noted that the inclined corner roller 41 is used to turn the strip material. The inclination angle of the corner roller 41 determines the turning direction of the strip material. In the preferred embodiment of this utility model, the winding direction of the strip material is the Y-axis direction and the unwinding direction is the X-axis direction. Considering the equipment floor area, the angle between the winding direction and the unwinding direction of the strip material is 90°. Therefore, the inclination angle of the corner roller 41 is 44°. After the strip material is turned by the corner roller 41, it is conveyed along the Y-axis towards the direction away from the winding device. After passing around the first conveying roller 42 and the second conveying roller 61 in sequence, it is conveyed along the top of the corner mechanism 4 towards the winding device.

[0050] Regarding the issue of equipment footprint, in existing slitting and winding equipment, the unwinding and slitting device is usually located at one end of the winding device, meaning the unwinding direction of the material is the same as the winding direction. The winding equipment typically uses winding devices arranged in a straight line to simultaneously wind multiple strips of material. Each strip of material corresponds to a winding roller in a single winding device. When dealing with wide rolls of material, the width of the unwinding and slitting device is often greater than the width of the winding device, resulting in the overall equipment being T-shaped. When modifying the unwinding and slitting device of the equipment later, the T-shaped equipment structure greatly limits the modification of its width direction.

[0051] In the technical solution of this utility model, the unwinding and slitting device is set on the side of the end of the winding device. The overall equipment is L-shaped. The unwinding direction of the unwinding and slitting device is perpendicular to the winding direction of the winding device. The corner conveying structure is set at the end of the winding device. The corner conveying structure is used to turn and lift the material. When encountering a roll of material with a large width, the width of the unwinding device is increased by modification. Compared with the traditional T-shaped equipment, the L-shaped equipment will not affect the overall width of the equipment when the width of the unwinding device is modified. A good passageway distance can be maintained between two adjacent main bodies 1 of the equipment.

[0052] In the technical solution of the first conveying roller 42 of this utility model, the second movable base 56 is provided with a vertical connecting part 561 at the position corresponding to both ends of the first conveying roller 42. The two ends of the first conveying roller 42 are hinged to the vertical connecting part 561. A gap is reserved between the bottom of the first conveying roller 42 and the second movable base 56. The two ends of the third movable base 43 are clamped upwards in a clamping shape at both ends of the corner roller 41. A gap is reserved between the bottom of the corner roller 41 and the third movable base 43.

[0053] like Figure 7 As shown, it should be noted that after the strip material turns and wraps around from bottom to top along the gap between the corner roller 41 and the third movable base 43, it wraps around from bottom to top along the gap between the first conveying roller 42 and the second movable base 56. After the strip material turns through the corner roller 41, it is output horizontally and is lifted and reversed by the first conveying roller 42 and the second conveying roller 61. The overall force on the strip material is more balanced. In the traditional method of setting a single corner roller 41 with inclination and angle to directly reverse the output of the material, the strip material will be subjected to the tilting and torsional force, and the transmission stability will be affected.

[0054] Furthermore, in the above scheme, a conveying bracket 6 is provided above the corner mechanism 4, and the conveying bracket 6 is provided with a plurality of second conveying rollers 61 aligned with the Z-axis direction of the first conveying roller 42. The second conveying rollers 61 are staggered layer by layer along the Y-axis direction.

[0055] It should be noted that the strip material conveyed by the corner roller 41 overlaps in the same Y-axis coordinate along the Z-axis direction. The first conveying roller 42 and the second conveying roller 61, which are arranged layer by layer, convey the strip material to the winding device one by one. The second conveying roller 61 is located above the corner conveying mechanism and the winding device. The strip material is conveyed to the winding roller of the winding device through the top of the equipment, making full use of the space above the equipment and reducing the floor space.

[0056] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
