Technical Field
[0001] The utility model relates to the technical field of sheet cutters, and more particularly to a sheet cutter for label rolls. Background Art
[0002] With the rapid development of advertising printing, packaging, and other fields, various types of label die-cutting machines have emerged. With roll-stock production becoming the mainstream, the demand for label roll cutting and shearing equipment is increasing, and the market's requirements for label products are becoming increasingly demanding. Traditional label die-cutting machines do not have the function of cutting individual label rolls. After die-cutting, label rolls must be cut to different lengths. To facilitate operation, cutting devices are added to die-cutters. However, this increases the difficulty of operating the entire machine, and the significant difference between the die-cutting speed and the shearing speed increases operating costs while hindering efficiency.
[0003] In order to solve the above problems, a separate label cutting machine is newly set up. The label cutting machine is used to cross-cut the rolled label materials. The label cutting machine mainly uses a conveyor roller to transport the label rolls, and then obtains the finished label products through the cutting tool. However, the cutting machine in the existing technology is prone to slipping when conveying the label rolls, causing the label rolls to deflect, resulting in the finished label products being skewed after cutting, seriously affecting the production quality of the finished label products, thereby reducing the finished product rate of the finished label products and increasing the cost of producing the finished label products.
[0004] Therefore, how to solve the problem that the existing cutting machine has low cutting efficiency and unstable length of the cut label products is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0044] It should be noted that the directional terms "front, back, left, right, up, and down" used below are defined based on the drawings in the specification. Furthermore, this application only describes one arrangement of the various mechanisms of a label web slitter. However, this arrangement is not limited to that described herein and may be arranged in other directions, all of which fall within the scope of protection of this utility model.
[0045] The core of the present utility model is to provide a label roll cutting machine, which can prevent the label roll 01 from slipping during transportation, prepare for the color mark sensor 32 to find the mark and position it, and achieve a fast and accurate positioning effect of the color mark sensor 32, so that the length of the finished labels cut by the cutting machine is consistent, thereby improving the qualified rate of the finished labels after cutting, and also improving the cutting efficiency of the continuous cutting machine.
[0046] Please refer to Figure 1 、 Figure 2 and Figure 3 A label roll cutting machine includes a platform body 1, a feeding mechanism 2, an adsorption mechanism 3, a color mark sensor 32, a control panel 4 and a conveying and cutting mechanism 5.
[0047] Specifically, a foldable feeding mechanism 2 is provided on one side of the platform body 1. When the breaking machine is used, the feeding mechanism 2 is unfolded, and when use is completed, the feeding mechanism 2 is folded to reduce the occupied space. By setting the feeding mechanism 2, the feeding and transmission of the label roll 01 can be realized. The feeding mechanism 2 has a guide structure 21 for controlling the direction of the label roll 01. By setting the guide mechanism on the feeding mechanism 2, the feeding path of the label roll 01 can be determined to prevent the label roll 01 from running off during the transportation process.
[0048] The adsorption mechanism 3 is provided on the platform body 1 and is located at the discharge end of the feeding mechanism 2, so that the feeding mechanism 2 can convey the label roll 01 to the adsorption mechanism 3. The adsorption mechanism 3 includes a vacuum adsorption platform 31 for adsorbing the label roll 01, and a color mark sensor 32 that is movable and provided on the vacuum adsorption platform 31 and is used to identify the marking point on the label roll 01. The vacuum adsorption platform 31 and the color mark sensor 32 are both connected to the control panel 4 on the platform body 1 by signal. The control panel 4 controls the negative pressure in the vacuum adsorption platform 31 to adsorb the label roll 01. 01 is adsorbed to ensure that the label roll 01 conveyed to the vacuum adsorption platform 31 can be transported smoothly and prevent the label roll 01 from deviating during the conveying process. The color mark sensor 32 is moved to the black mark point printed on the label roll 01 for precise positioning, and the positioning information is sent to the control panel 4. The control panel 4 determines the cutting length of each page of the label roll 01 according to the spacing between the mark points equidistantly distributed in the conveying direction of the label roll 01, so as to further convey the label roll 01 of the specified length to the conveying and cutting mechanism 5 for cutting.
[0049] The conveying and cutting mechanism 5 is provided on the platform body 1 and is located at one end of the vacuum adsorption platform 31 away from the loading mechanism 2, so that the label roll 01 is conveyed to the conveying and cutting mechanism 5 through the vacuum adsorption platform 31, and the label roll 01 is cut and broken by the conveying and cutting mechanism 5. The conveying and cutting mechanism 5 includes a pressure regulating device 52 for adjusting the pressure of the conveying roller group 51 conveying the label roll 01, a pressing component 53 provided at the discharge end of the conveying roller group 51 and used to flatten the label roll 01, and a cutting component 54 provided at the discharge end of the pressing component 53 and used to cut the label roll 01. The conveying roller group 51 and the cutting component 54 are both connected to the control panel 4 by signal, and the control panel 4 controls the conveying roller group 51 to convey the label roll 01. 1 to the pressing component 53, the label roll 01 is flattened by the pressing component 53 to avoid curling of the label roll 01, thereby ensuring the conveying effect of the label roll 01, and the cutting component 54 is controlled by the control panel 4 to cut the label roll 01 on the pressing component 53, thereby completing the breaking of the label roll 01, and adjusting the pressure regulating device 52 to keep the force at both ends of the label roll 01 consistent, which can ensure that the label roll 01 is conveyed smoothly and prevent the label roll 01 from slipping and wrinkling during the conveying process due to inconsistent pressure at both ends, thereby affecting the feeding accuracy and cutting effect. The pressure regulating device 52 can also be adjusted to be applied to the transmission of label rolls 01 of different thicknesses.
[0050] The guide structure 21 of the feeding mechanism 2 guides the direction of the label roll 01 to prevent the label roll 01 from deviating during the feeding and conveying process. The vacuum adsorption platform 31 of the adsorption mechanism 3 adsorbs the label roll 01 so that the label roll 01 can be transported smoothly to prevent the label roll 01 from deviating or curling during the adsorption and conveying process. The pressure regulating device 52 is adjusted to keep the pressure on both ends of the label roll 01 conveyed by the conveying roller group 51 consistent, so as to ensure that the label roll 01 is conveyed smoothly and prevent the label roll 01 from slipping or wrinkling during the conveying process of the conveying roller group 51. The label roll 01 conveyed by the conveying roller group 51 is flattened to prevent the label roll 01 from curling. That is to say, the guide structure 21, the vacuum adsorption platform 31, the pressure regulating device 52 and the pressing assembly 53 cooperate with each other to prevent the label roll 01 from curling, deviation and slipping during the entire conveying process, thereby preparing for the color mark sensor 32 on the vacuum adsorption platform 31 to locate the mark, so as to ensure that the color mark sensor 32 can quickly, accurately and effectively achieve positioning, thereby preparing for the effective cutting of the label roll 01, improving the cutting efficiency of the label roll 01 and the qualified rate of the finished label products after breaking.
[0051] The label roll cutting machine set up in the above manner can achieve accurate transportation of the label roll 01, avoid the label roll 01 from slipping during transportation, thereby achieving fast, accurate and effective positioning of the color mark sensor 32, improving the cutting efficiency of the label roll 01, and improving the qualified rate of the finished labels after cutting by the cutting machine.
[0052] Please refer to Figure 4 The vacuum adsorption platform 31 is provided with a first positioning guide rail 33 extending along the transmission direction of the label roll 01 and a second positioning guide rail 34 extending perpendicular to the transmission direction of the label roll 01. The second positioning guide rail 34 is movably provided on the first positioning guide rail 33. A movable color mark sensor 32 is provided on the second positioning guide rail 34. The color mark sensor 32 is movably set along the transmission direction of the label roll 01 through a fine adjustment structure 35.
[0053] It should be noted that the suction mechanism 3 is located to the left of the loading mechanism 2 and is fixed to the platform body 1 on both the front and rear sides. The suction mechanism 3 includes a vacuum suction platform 31 and a fan 36 located at its bottom. The fan 36 is mounted to the bottom of the cavity of the suction panel of the vacuum suction platform 31. The fan 36 is connected to the control panel 4 by signal. The control panel 4 controls the operation of the fan 36 to put the vacuum suction platform 31 in a negative pressure suction state, thereby sucking the label roll 01 on the vacuum suction platform 31. This ensures that the label roll 01 delivered to the vacuum suction platform 31 can be transported smoothly and prevent the label roll 01 from deviating during transportation. First positioning guide rails 33 are respectively provided on the front and rear sides above the suction panel. A guide rail fixing block is installed above the slider of the first positioning guide rail 33 to fix the second positioning guide rail 34 in the vertical direction. The vacuum suction platform 31 can suck the label roll 01 flat, facilitating the color mark sensor 32 above it to find the mark and position it, thereby improving the conveying accuracy of the label roll 01, achieving precise sheet breaking, and reducing its dimensional error to obtain a finished sample of the specified length requirement.
[0054] A fine-adjustment structure 35 is installed on the slider of the second positioning guide rail 34. The fine-adjustment structure 35 includes a guide block fixed on the slider and an adjustment bracket slidingly arranged along the guide block. The adjustment bracket is a U-shaped structure and is sleeved on the outside of the guide block. The opening of the adjustment bracket is set to the left. A guide plate is provided on the upper part of the guide block. The guide plate is fixed to the guide block and contacts with the upper end face of the adjustment bracket. The guiding effect of the adjustment bracket is achieved through the cooperation of the guide plate and the guide block. The adjustment bracket can move left and right, that is, it can move along the direction of transmission of the label roll 01 and in the direction opposite to the transmission direction of the label roll 01.
[0055] The left end of the adjusting bracket is connected to the fixed plate, and the color mark sensor 32 is fixed on the fixed plate. The color mark sensor 32 moves synchronously with the adjusting bracket. A hand screw is provided on the right side of the adjusting bracket. The hand screw passes through the adjusting bracket and the guide block, and a spring is provided on the outer periphery of the hand screw. The two ends of the spring are respectively in contact with the left end face of the adjusting bracket and the right end face of the guide block. This arrangement enables the spring to be compressed and reset during the left and right movement of the adjusting bracket.
[0056] In this embodiment, when the fine adjustment structure 35 is used to adjust the position of the color mark sensor 32, by rotating the thumb screw in the forward direction, the adjustment bracket can be moved in the direction of conveying the label roll 01, thereby driving the color mark sensor 32 to move in the direction of conveying the label roll 01. By rotating the thumb screw in the reverse direction, the adjustment bracket can be moved in the direction opposite to the conveying direction of the label roll 01, thereby driving the color mark sensor 32 to move synchronously.
[0057] In actual application, the hand screw can be rotated in the reverse direction to move the adjustment bracket along the direction of the label roll 01, thereby driving the color mark sensor 32 to move along the direction of the label roll 01. By rotating the hand screw in the forward direction, the adjustment bracket can be moved in the direction opposite to the transmission direction of the label roll 01, thereby driving the color mark sensor 32 to move synchronously. There is no restriction on this, as long as the above technical effect can be achieved.
[0058] By moving the color mark sensor 32 on the first positioning guide rail 33 and the second positioning guide rail 34, the position of the color mark sensor 32 on the adsorption panel is controlled, that is, the color mark sensor 32 is preliminarily aligned with the black mark point on the label roll 01, and the position of the color mark sensor 32 in the transmission direction of the label roll 01 is further accurately adjusted by tightening the screws, thereby achieving a precise positioning effect, thereby improving the accuracy of conveying and breaking the label roll 01, so as to obtain finished labels with different length requirements.
[0059] After the label roll 01 is placed on the suction panel, the control panel 4 controls the fan 36 below the suction panel to rotate, thereby forming a negative pressure in the cavity of the suction panel. The label roll 01 above is sucked and flattened through the small holes on the upper surface of the suction panel. The first positioning guide 33 and the slider on the second positioning guide 34 provided above are further moved, that is, the second positioning guide 34 as a whole and the adjustment bracket on its slider are moved to roughly position the color mark sensor 32 in the front, back, left, and right positions on the suction panel. The hand screw is further rotated to move the color mark sensor 32 on the adjustment bracket to accurately position the black mark dots or other color blocks printed on the label roll 01 below. After positioning is completed, the cutting length of each page of the sample is determined according to the spacing between the black mark dots evenly distributed in the conveying direction of the label roll 01, so that the label roll 01 of the specified length can be further conveyed to the sheet breaking section for cutting. In addition, the waste edges between the samples can be processed according to the different spacing sizes of the mark dots, and only the finished sample is retained. The adsorption mechanism 3 can ensure that the label roll 01 remains flat and stable during transportation, and can search and locate each black mark point or color block on the label roll 01, thereby improving the accuracy of conveying and breaking the label roll 01 to obtain finished labels with different length requirements.
[0060] Furthermore, the black mark point or the color block with large color difference change on the label roll 01 is used as the positioning point, and the color difference detection and calibration of the color mark sensor 32 is set, and the cutting length value and the deviation value are set, and finally the finished label is obtained, specifically:
[0061] Place the label roll 01 to be transported on the adsorption panel in the same manner as described above.
[0062] Select a black mark printed on the label roll 01 or a color block with a large color difference as the positioning point, move the color mark sensor 32 to align with this position, set the color mark reading of this positioning point and other color areas to perform color difference inspection and calibration, thereby providing a response signal to the control panel 4, thereby affecting the operation of the entire machine. To prevent the deviation of the cutting length caused by the left and right movement of the label roll 01, the positioning point should be selected close to the vertical direction of the movement to avoid obvious arc at this position;
[0063] The cutting length value a and the deviation value b are preset through the control panel 4;
[0064] The label roll 01 is transported to the cutting area for the first trial cut, and the sample after cutting is checked to see if it meets the preset length a. If so, batch production can be carried out. If not, the system checks whether a similar color mark point at the front of the positioning point or the previous positioning color mark point is selected, and the preset length is adjusted to a+Δa. Another trial cut is then carried out. This process is repeated to determine the length value and deviation value that meet the actual sample length requirements, and finally the finished label product is obtained for batch production.
[0065] Among them, since the response time t of the color mark sensor 32 cannot meet the detection of the color mark on the high-speed moving object, resulting in color mark detection errors, the control panel 4 decelerates the moving speed of the label roll 01 according to the preset length a, that is, between two adjacent positioning color mark points, when the label roll 01 starts to move from the first positioning color mark point, the label roll 01 is controlled to move normally, and when the label roll 01 is about to move to the other positioning color mark point, the label roll 01 is controlled to move at a slower speed, thereby ensuring the reliability of color mark detection.
[0066] Please refer to Figure 3 and Figure 5 The conveying roller group 51 includes a transmission roller 511 and a pressure roller 512 arranged directly above the transmission roller 511. The transmission roller 511 abuts against the outer peripheral surface of the pressure roller 512. It also includes a first motor connected to the control panel 4 signal. The first motor is connected to the transmission roller 511 and is used to drive the transmission roller 511 to rotate, so as to drive the pressure roller 512 and the transmission roller 511 to rotate synchronously.
[0067] It can be understood that the two ends of the transmission roller 511 are fixed to the platform body 1 on the front and rear sides through bearings 525 respectively. A pressure roller 512 is provided above the transmission roller 511, and pressure regulating devices 52 for controlling the pressure of the pressure roller 512 are symmetrically arranged on both sides of the pressure roller 512. The pressure regulating device 52 is used to ensure the smoothness of the conveying of the label roll 01 below. When in use, the control panel 4 controls the operation of the first motor to drive the transmission roller 511 to rotate, and the transmission roller 511 drives the pressure roller 512 to rotate synchronously to realize the conveying of the label roll 01.
[0068] Furthermore, the pressure roller 512 has a pressure roller 512 shaft, and the pressure regulating device 52 includes a support 521 arranged at both ends of the pressure roller 512 shaft, the support 521 is arranged on the platform body 1, and a movable sliding pressure block 522 is provided in the slide groove of the support 521. The sliding pressure block 522 is limited in the slide groove by the compression spring 523 and the limit screw 524 at the top of the support 521. The sliding pressure block 522 is rotatably connected to the pressure roller 512 shaft, and a rotatable bearing 525 is provided on one side of the bottom of the support 521. The pressure roller 512 shaft is provided with an eccentric portion corresponding to the bearing 525, and the pressure roller 512 shaft is also provided with a fixed handle 526.
[0069] It should be noted that sliding pressure blocks 522 are symmetrically mounted on either side of the pressure roller 512 shaft, mounted in the slideways of the supports 521 on either side. Compression springs 523 are located above these blocks, and stop screws 524 are located above these blocks to compress the compression springs 523. Bearings 525 are symmetrically fixed to the sides of the bottoms of the supports 521 on either side. Eccentric portions are located on either side of the pressure roller 512 shaft, corresponding to the positions of the bearings 525 on either side. A fixed handle 526 is also mounted on one end of the pressure roller 512 shaft. The pressure on either side of the pressure roller 512 is adjusted using an adjustment device to ensure consistent pressure on both ends of the label roll 01 for different thicknesses, maintaining a smooth surface during transport. The pressure roller 512 is lifted by turning the fixed handle 526 on the pressure roller 512 shaft to adjust the position of the label roll 01.
[0070] The pressure roller 512 presses the label roll 01 onto the lower transmission roller 511, and the upper and lower positions and pressures of the two ends of the pressure roller 512 are controlled by manually adjusting the adjustment devices on both sides of the pressure roller 512, that is, manually adjusting the compression amount of the compression spring 523 by the limit screw 524, so that the forces on both ends of the label roll 01 remain consistent. Since there are eccentric points on both sides of the pressure roller 512 shaft, by rotating the fixed handle 526 on the pressure roller 512 shaft, the pressure roller 512 shaft is lifted up by the bearings 525 fixed on the adjustment devices on both sides, so that the pressure roller 512 is lifted up to facilitate the adjustment of the direction and position of the label roll 01. For label rolls 01 of different thicknesses, the pressure at both ends of the pressure roller 512 can be manually adjusted to ensure that the label roll 01 is conveyed smoothly, and the label roll 01 can be prevented from slipping and wrinkling during the conveying process due to inconsistent pressure at both ends, which affects the feeding accuracy and cutting effect. Moreover, there is no need to repeatedly adjust the pressure after it is set. The eccentric part on both sides of the axis of the pressure roller 512 can be used to lift the pressure roller 512 by rotating the fixed handle 526, which facilitates the loading and unloading of the label roll 01 and the adjustment of the position of the label roll 01. The structure is simple and effective, and debugging is convenient.
[0071] Please refer to Figure 3 and Figure 5The pressing assembly 53 includes a pressing shaft 531, a pressing platform 532 and a silicone ring 533. The pressing platform 532 is arranged on the platform body 1. The pressing shaft 531 is rotatably connected to the platform body 1 and is located on the top of the pressing platform 532. The silicone ring 533 is wrapped around the outer periphery of the pressing shaft 531 and the pressure roller 512 so that the pressing shaft 531 and the pressure roller 512 rotate synchronously. The silicone ring 533 wrapped around the pressing shaft 531 is in contact with the pressing platform 532, and the outer periphery of the pressure roller 512 is provided with a cutting groove 534 for installing the silicone ring 533.
[0072] The cam 533 is pressed against the top of the pressing roller 512 to release the pressure, so that the label roll 01 below the pressing roller 512 is pressed down and the label roll 01 below the pressing roller 512 is cut off.
[0073] Please refer to Figure 3 、 Figure 6 and Figure 7 The cutting assembly 54 is arranged at the discharge end of the pressing table 532. The cutting assembly 54 includes a fixed knife 541 and a movable knife 542. The movable knife 542 is fitted with the fixed knife 541 through an adjusting device. The adjusting device includes a long bolt 543 for connecting the fixed knife 541 and the movable knife 542. The end of the long bolt 543 is provided with a fixed pad 544, a spring 545, a gasket 546 and a lock nut 547. The movable knife 542 is provided with a long hole 5421 for installing the long bolt 543 so that the movable knife 542 can move along the side of the fixed knife 541. The movable knife 542 is driven by a second motor 55 connected to the signal of the control panel 4 so that the movable knife 542 can move along the side of the fixed knife 541.
[0074] It should be noted that a fixed knife 541 is fixed to the left side wall of the pressing table 532, and a movable knife 542 that fits into the fixed knife 541 is provided on the left side of the fixed knife 541, and adjustment devices for adjusting the gap between the two blades are provided on both sides of the movable knife 542. At the same time, the two end faces of the movable knife 542 are respectively hinged to the upper end of the joint connecting rod 56, and the lower end of the joint connecting rod 56 is respectively hinged to the heads of the linkage blocks 57 located on the front and rear sides. The linkage blocks 57 are connected and fixed to the knife-dropping transmission shaft 58 through keyways. A linkage block 57 is also fixed to the front end face of the knife-dropping transmission shaft 58, and its head is hinged to the upper end of another joint connecting rod 56. The lower end of the joint connecting rod 56 is hinged to the eccentric point of the rotating block 59 located below, and the rotating block 59 is connected to the output shaft of the second motor 55. A long bolt 543 is installed on the right side wall of the fixed knife 541, and then the long bolt 543 is inserted through the long holes 5421 on both sides of the movable knife 542 and fits to the left side wall of the fixed knife 541. Then, fixed pads 544 are provided on both sides of the movable knife 542 and the long bolt 543 is inserted through them. Then, a spring 545 and a gasket 546 are inserted on the left side of the fixed pad 544. Finally, anti-loosening nuts 547 are fixed to the left ends of the long bolts 543.
[0075] To ensure that the two blades fit closely, long bolts 543 are used on the right side of the fixed knife 541 and the movable knife 542 to determine their installation and movable positions, and the fixed pad 544 is inserted into the bolts on both sides and pressed onto the movable knife 542, and the spring 545 and gasket 546 are inserted into the left side of the fixed pad 544. Finally, the anti-loosening nut 547 is screwed to the appropriate position to ensure that the spring 545 is stressed and the movable knife 542 is pressed tightly to the fixed knife 541 to ensure fit. By adjusting the compression amount of the spring 545, the gap between the two blades can be reduced, and the vibration generated by the blades during the cutting process can be reduced to a certain extent. The cutting quality is guaranteed to avoid burrs, uneven cuts, and continuous cutting on the label roll 01.
[0076] The movable blade 542 is hinged on both sides of the joint link 56, and the bottom of the joint link 56 is hinged to the linkage block 57 and fixed to the blade drop transmission shaft 58 on both sides. A second motor 55 is used to drive the blade drop shaft to rotate, thereby ensuring the consistency of the blade drop on both sides of the movable blade 542. The joint link 56 on both sides below the movable blade 542 is respectively hinged to the linkage block 57 and fixed to the blade drop transmission shaft 58 through a keyway connection, thus forming an integral unit. That is, the swing of the blade drop transmission shaft 58 in the circumferential direction is converted into the vertical movement of the movable blade 542, thereby cutting the label roll 01 into pieces, and the transmission structure is stable and reliable. The linkage block 57 and the keyway connection are used to fix it to the blade drop transmission shaft 58 as a whole, so that the installation position of the two sides is consistent, thereby ensuring the consistency of the movement of the movable blade 542 on both sides when the blade drop transmission shaft 58 rotates, and the structure is more stable and reliable.
[0077] Please refer to Figure 2 and Figure 8 The platform body 1 is provided with an incoming material detection sensor 6 , which is used to detect the label roll 01 on the feeding mechanism 2 in real time and send the signal of the detected label roll 01 to the control panel 4 .
[0078] It can be understood that the incoming material detection sensor 6 detects in real time whether there is a label roll 01 on the feeding mechanism 2, and sends the detected signal to the control panel 4, which controls the entire machine to transport and break the label roll 01.
[0079] Please refer to Figure 7 A foldable material receiving mechanism 7 is provided on the other side of the platform body 1. The material receiving mechanism 7 includes a material receiving hopper 71. A guide baffle 72 is provided in the material receiving hopper 71. The material receiving hopper 71 is rotatably connected to the platform body 1 through a positioning shaft 73. The material receiving hopper 71 is foldably provided on the platform body 1 through a self-locking telescopic support rod 74.
[0080] It should be noted that the right side of the hopper 71 uses the positioning shaft 73 as a fulcrum and is fixed to the front and rear sides of the positioning shaft 73 via connecting blocks. At the same time, the end faces of the hopper 71 are hinged to the upper ends of the telescopic struts 74, and the lower ends of the telescopic struts 74 are fixed to the front and rear sides of the positioning shaft 73 located below by fixing blocks, thereby realizing the folding function of the hopper 71. The hopper 71 uses the positioning shaft 73 at the left end of the platform body 1 as a fulcrum. After the hopper 71 is manually lifted, the telescopic struts 74 self-lock and fix it to the appropriate angle position, thereby forming a slope to facilitate the falling and stacking of the finished labels. At the same time, the hopper 71 can be folded as a whole, saving space and facilitating operation.
[0081] Among them, by setting the guide baffle 72, the positioning and collection of the finished label products are achieved. In this embodiment, the receiving hopper 71 is set in this way to achieve folding, but in actual application, there is no limitation to this, as long as the above-mentioned technical effects can be achieved.
[0082] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 8 The loading mechanism 2 includes a feeding bracket 22, which is foldably arranged on the platform body 1 through a telescopic support rod 74. The feeding bracket 22 includes two parallel conveying arms 221 and a fixed shaft 222 for connecting the conveying arms 221, and a conveying shaft 223 rotatably connected to the conveying arms 221. The conveying arms 221 are rotatably connected to the platform body 1 through a support block 224. A guide structure 21 is provided on the inner side of the conveying arm 221, and the guide structure 21 is movably arranged along the fixed shaft 222 and the conveying shaft 223.
[0083] The support blocks 224 are symmetrically arranged in the feeding mechanism 2 and are respectively fixed to the right ends of the platform bodies 1 on the front and rear sides. The bottoms of the support blocks 224 are hinged to the conveying arms 221 through bearings. The conveying arms 221 are evenly distributed with fixing holes of the fixed shaft 222 and mounting holes of the bearings 525. The fixed shaft 222 and the conveying shaft 223 are thus installed to determine the feeding path of the label roll 01. A guide structure 21 is symmetrically provided on the shaft. The guide structure 21 includes a baffle 211, a fixed block 212 and a screw 213. By tightening or loosening the screw 213, the baffle 211 can be moved along the fixed shaft 222 and the conveying shaft 223. After the baffle 211 is moved to a suitable position, the screw 213 is tightened to lock the baffle 211. The feeding path and position of the label roll 01 are determined by the evenly distributed fixed shafts 222, the conveying shaft 223 and the baffle 211. A support plate 23 is fixed under the conveying arms 221 on both sides and is hinged to the upper end of the telescopic support rod 74. At the same time, the lower end of the telescopic support rod 74 is hinged to the fixing plate 24 and fixed to the platform body 1 on both sides, thereby realizing the overall folding function of the feeding mechanism 2.
[0084] Before loading the label roll 01, the feeding bracket 22 needs to be lifted, and the telescopic struts 74 on both sides are self-locked to fix the loading mechanism 2 to a suitable angle position. Manually pass the label roll 01 from the right side through the fixed shafts 222 and the conveying shaft 223 alternately up and down to give the label roll 01 a certain tension and ensure its smooth conveying. The label roll 01 is clamped by the baffle 211 to determine the overall direction and position of the label roll 01, and then fixed with the screws 213 above the fixing block 212 to prevent the label roll 01 from deviating during the conveying process.
[0085] When using the label roll cutting machine, before loading the label roll 01, the feeding bracket 22 of the loading mechanism 2 needs to be lifted up, and the telescopic struts 74 on both sides are self-locked to fix the loading mechanism 2 to a suitable angle position. Manually pass the label roll 01 from the right side through the fixed shafts 222 and the conveying shafts 223 alternately up and down to give the label roll 01 a certain tension and ensure its smooth conveying. The label roll 01 is clamped by the baffle 211 to determine the overall direction of the label roll 01, and then fixed with the screws 213 above the fixing block 212 to prevent the label roll 01 from During the conveying process, the label roll 01 deviates, and then the label roll 01 is placed on the adsorption panel. The fixed handle 526 on the pressure roller 512 shaft is rotated to lift the pressure roller 512 to adjust the position of the label roll 01. Then the pressure roller 512 is lowered to complete the preliminary feeding of the label roll 01. Manually adjust the sliders on the first positioning guide rail 33 and the second positioning guide rail 34 to roughly adjust the position of the color mark sensor 32 on the adsorption panel so that the color mark sensor 32 is aligned with the black mark point on the label roll 01. Then manually adjust the fine adjustment structure 35 to accurately adjust the color mark sensor 32 so that the color mark sensor 32 is aligned with the black mark point on the label roll 01. It is aligned with the black mark point on the label roll 01 to complete the precise positioning of the color mark sensor 32; manually adjust the adjustment devices on both sides of the pressure roller 512 to keep the force on both ends of the label roll 01 consistent to ensure the smooth transportation of the label roll 01; start the cutting machine, control the cutting machine to run to the preset time and then stop, and judge whether the finished label after the cutting machine meets the rectangular shape and length requirements. If the finished label does not meet the rectangular shape requirements, it means that the pressure on both sides of the pressure roller 512 is inconsistent, resulting in inconsistent force on both ends of the label roll 01. Therefore, it is necessary to adjust the pressure regulating device Set 52, and / or, if the finished label does not meet the length requirement, it means that there is a problem with the mark point aligned with the color mark sensor 32, so it is necessary to adjust the color mark sensor 32 to realign with another mark point on the label roll 01, and start the cutting machine, control the cutting machine to run for a preset time and then stop, and judge whether the finished label after the cutting machine cuts meets the rectangular shape requirement and the length requirement, until the finished label after the cutting machine cuts meets the rectangular shape requirement and the length requirement; when the finished label meets both the rectangular shape requirement and the length requirement, restart the cutting machine to mass produce the finished label.
