Description

Technical Field

[0001] The invention belongs to the technical field of laser printers, and in particular relates to a fully automatic laser printer for flexible materials with tension material collection. Background Art

[0002] Flexible materials refer to materials with flexible and fully flexible properties. They can maintain their structural and functional integrity under a certain degree of deformation (such as bending, folding, twisting, compression or stretching). As a result, when flexible materials are used in the electronic field, they can provide flexibility and bendability that traditional rigid materials cannot achieve.

[0003] The winding reel of the existing laser marking machine winding mechanism uses a spring to provide a resistance. During installation, the gasket on the winding reel is used to lock the nut, and there is a spring between the gasket and the locking nut. When used, the spring is compressed, the fixed pressure is greater, and the friction force becomes greater accordingly. When the corresponding winding reel rotates, a damping force appears, thereby adjusting the tension of the winding reel.

[0004] However, when the above method is used for winding, due to the soft and deformable characteristics of the flexible material, it is difficult to meet the requirements for precise control of the tension of the flexible material, resulting in looseness or over-tightness during winding, which in turn leads to unachievable uniform winding and even batch scrapping.

[0095] The printing method of the fully automatic laser printer for flexible materials with tension material collection comprises the following specific steps:

[0096] S1. First, place the material on the unwinding mechanism, and manually rotate the tensioning knob of the unwinding mechanism to tighten the unwinding shaft of the unwinding mechanism until the material is locked and no longer slides relative to the unwinding shaft;

[0097] S2. Press the reset button of the tension controller to adjust the tension to the initial value;

[0098] S3, bend the wrench to the inside so that the two sets of rollers are in the rising state;

[0099] S4, drag the material so that the material passes through the gap between the pressure roller and the support roller at the inlet end of the feeding mechanism and enters the induction slot of the feeding mechanism;

[0100] S4.1. If the sensor installed in the sensing tank senses the material and the sensor indicator light goes out, then proceed to the next step;

[0101] S4.2. The staff drags the material, and the material passes through the gap between the pressure roller and the supporting roller arranged at the outlet end of the feeding mechanism, and enters the shearing mechanism through the inlet of the shearing mechanism;

[0102] S4.3. Workers drag the material through the shear, and

[0103] The blank of the material is wound on the winding yarn of the winding mechanism, and

[0104] Manually rotate the tensioning knob of the winding mechanism to tighten the winding shaft of the winding mechanism until it is locked. After locking, install the positioning disk and lock the positioning disk through the quick locking mechanism;

[0105] S4.3, if the sensor installed in the sensing tank does not sense the material, the sensor indicator light is on, reminding the staff to check, until the sensor indicator light goes out, and then go to step S4.2;

[0106] S5. After the positioning plate is locked, the staff pulls the end of the material so that the material is parallel to the feeding path; then bend the wrench and pull the wrench back to the outside, and

[0107] The two sets of pressing rollers are in a compacting state, and the materials are compacted by the two sets of pressing rollers;

[0108] S6. Check whether the laser printer switch button is turned on. If it is turned on, the indicator light will be on.

[0109] Then set the corresponding parameters, select the pattern to be printed, and make adjustments;

[0110] Finally, press the switch to start marking until the target is reached;

[0111] S7. After reaching the target, the staff will determine whether cutting is needed based on the actual production situation.

[0112] If cutting is to be performed, press the left and right adjustment button on the panel to adjust the left and right positions of the scissors of the cutting mechanism so that the cutting position of the scissors is just in the middle of the two marked contents. After the left and right positions of the cutting mechanism are confirmed, press the switch of the cutting mechanism to cut;

[0113] If shearing is not required, the material is wound around the winding mechanism through the shearing mechanism.

[0114] In summary, the beneficial effects of the present invention are:

[0115] (1) The present invention automatically adjusts the tension of the winding mechanism by adding a winding mechanism and a magnetic powder clutch, thereby enabling the winding mechanism to maintain a stable tension during the winding process, ensuring the flatness and consistency of the material during the conveying process, and avoiding the situation where the material becomes loose or too tight during the conveying process.

[0116] (2) The present invention adds a feeding mechanism and uses the feeding mechanism and the magnetic powder clutch in combination to solve the problem that the flexible material is soft and easy to deform, which makes it easy for the pressure roller to press the inlet and outlet ends of the material during winding, thereby avoiding the material bending or shrinking during the printing process, resulting in distortion, misalignment or inaccurate size of the printed pattern.

[0117] (3) The present invention uses a combination of air cooling and water cooling to efficiently dissipate heat from the magnetic powder clutch, thereby improving the heat dissipation efficiency, thereby ensuring the reliability and accuracy of the magnetic powder clutch during operation, thereby maintaining a stable tension during the material winding process.

[0162] The present invention is mainly used in the field of flexible electronic manufacturing.

[0163] like Figures 1 to 13As shown, this embodiment provides a flexible material full-automatic laser printer 100 with tension material collection, including a body 20, and the body 20 is provided with a reeling mechanism 40 for winding materials (label rolls), and the material passes through the reeling mechanism 40 and extends into the feeding mechanism 30, and the reeling mechanism 40 is driven by a servo motor 403, and the other end of the material passes through the feeding mechanism 30 and is wound on the reeling mechanism 10; the reeling mechanism 40 includes a reeling tension controller 401, and the reeling mechanism 40 also includes an encoder 402. , and the encoder 402 is installed on the servo motor 403; the cavity of the body 20 is divided into two groups of front and rear cavities by a partition, and a servo motor 403 is fixedly installed in one group (the rear cavity), and the driving end of the servo motor 403 passes through the partition and extends into the other group of cavities, and is connected to the unwinding roller shaft through a bearing assembly, an unwinding disk is provided on the unwinding roller shaft, and a magnetic powder brake 404 is installed on the unwinding roller shaft, the magnetic powder brake is used in conjunction with the unwinding tension controller 401, and the tension of the unwinding roller shaft is adjusted by the magnetic powder brake.

[0164] Furthermore, the winding mechanism 10 includes a winding drive system 102, and the winding drive system 102 is preferably a stepping motor. The driving end of the winding drive system 102 is connected to the rotating shaft 106 through a bearing assembly. The rotating shaft 106 is provided with a magnetic powder clutch 103. The magnetic powder clutch 103 is used in conjunction with the winding tension controller 101. The winding tension controller 101 and the unwinding tension controller 401 are used to adjust the tension of the winding mechanism 10 and the unwinding mechanism 40.

[0165] In this embodiment, the winding tension controller 101 detects the tension during winding, and transmits the detected tension to the control system of the laser printer for calculation, and transmits the required signal to the winding tension controller, which transmits the signal to the magnetic powder clutch, and automatically adjusts the tension through the magnetic powder clutch.

[0166] Furthermore, a belt 104 is installed on the driving pulley arranged on the rotating shaft 106, and the other end of the belt 104 is sleeved on the driven pulley 105 to form a belt drive, and the axle of the driven pulley 105 passes through the partition and is connected to the winding disk 1021. A positioning disk 1022 is provided at a relative position of the winding disk 1021, and is fixedly connected by a tensioning knob 1024.

[0167] During installation, it is only necessary to sleeve the positioning disk onto the axle, and to make the locking ring 1023 of the tensioning knob 1024 contact the inner wall of the positioning disk 1022 , and then to lock it by the tensioning knob 1024 .

[0168] The machine body 20 is provided with a controller 202 , and is wirelessly connected to the touch screen 201 , the display screen 204 , the alarm 50 , the unwinding tension controller 401 and the winding tension controller 101 .

[0169] In actual application, since flexible materials are soft and easy to deform, they are prone to bending or shrinking during the printing process, resulting in distortion, misalignment or inaccurate size of the printed pattern. To solve the above technical problems, please refer to Figure 2 and Figure 4 As shown, a feeding mechanism 30 is provided between the winding mechanism 10 and the unwinding mechanism 40, and a pulsed continuous fiber laser for printing the material is provided directly above the feeding mechanism 30, and the light is emitted through the laser galvanometer 60. The high energy density laser is transmitted by optical fiber, and the light is emitted through the optical fiber galvanometer to print the material;

[0170] The feeding mechanism 30 includes a mounting seat 305, and the mounting seat 305 is fixedly mounted on the partition of the body 20 by fastening screws, a frame 308 is fixedly mounted on the mounting seat 305, and a roller 307 is arranged between the frame 308 and the mounting seat 305, and a position-adjustable pressure roller 301 is arranged above the roller 307, and materials are placed between the roller 307 and the pressure roller 301, and the inlet and outlet ends of the materials are pressed by the pressure roller 301 to avoid distortion, misalignment or inaccurate size of the printed pattern due to bending or shrinkage of the material during the printing process.

[0171] Furthermore, both ends of the pressing roller 301 are mounted on an adjustment plate 309, and the adjustment plate 309 is slidably mounted in a slide groove provided in the mounting seat 305, so that the adjustment plate 309 can move up and down in the slide groove;

[0172] An adjustment rod 306 is fixedly mounted on the end surface of the adjustment plate 309 at a position away from the pressure roller 301, and a positioning column 304 is provided on one side of the adjustment rod 306, and one end of the adjustment rod 306 and the positioning column 304 passes through the horizontal plate of the frame 308;

[0173] The eccentric shaft 303 located between the adjusting rod 306 and the positioning column 304 passes through the horizontal plate of the frame 308 and is connected to the wrench 302 through a hinge.

[0174] A spring is installed on the eccentric shaft 303 between the transverse plate of the frame 308 and the top end of the adjustment plate 309 .

[0175] In this embodiment, the two wrenches 302 are moved, and the adjustment rod extends into the positioning groove of the wrench 302. Figure 4As shown, when the wrench 302 is in the Figure 4 In the state, the eccentric shaft drives the adjustment plate 309 to rise, thereby lifting the pressure roller, so that the material can pass through the gap between the pressure roller and the supporting roller;

[0176] Then pull the wrench back to the outside so that the positioning column 304 extends into the positioning groove of the wrench 302. At this time, the eccentric shaft drives the adjustment plate to descend, thereby pressing the pressure roller downward, so that the material can be compacted by the pressure roller and the supporting roller.

[0177] See also Figure 2 and Figure 3 As shown, a shearing mechanism 70 is provided on one side of the feeding mechanism 30 and is driven by a stepper motor 701. In actual application, it can be determined whether the material needs to be sheared according to the actual situation. If shearing is required, it is only necessary to start the stepper motor 701 and drive the shearing mechanism 70 to shear the material through the stepper motor 701.

[0178] The magnetic powder clutch adjusts the tension by adjusting the magnetic field strength. When no power is applied, the input shaft rotates, the output shaft and the input shaft are not in contact, and the input shaft is in an idling state; when working, the current flows through the coil to generate a magnetic field inside the magnetic powder clutch. The strength of the magnetic field is controlled by the current. When the coil generates a magnetic field, the magnetic powder begins to gather under the force of the magnetic field to form a magnetic chain, thereby achieving synchronous rotation of the input shaft and the output shaft. The tension can be precisely controlled by adjusting the current.

[0179] When the magnetic powder clutch runs at high speed or works for a long time, a lot of heat will be generated. As the temperature rises, the magnetic powder is affected by the temperature, causing the magnetic permeability of the magnetic powder to change, which in turn causes the magnetic field to change, thus affecting the precise control of the tension. To solve the above technical problems, please refer to Figure 5-12 As shown, the magnetic powder clutch 103 includes an input shaft 1036 and a stator 1039, and an active rotor 1038 coaxially fixed on the input shaft 1036.

[0180] The magnetic powder clutch 103 further includes an output shaft 1037 and a driven rotor coaxially fixed to the output shaft 1037.

[0181] An accommodation space for placing the coil 901 is provided between the coil seats of the magnetic powder clutch 103, and a through hole is provided on the coil seat, through which a wire can pass and enter the accommodation space to be electrically connected with the coil 901, and a magnetic powder gap 902 connected to the accommodation space is provided between the outer peripheral wall of the stator 1039 and the outer wall of the coil seat;

[0182] The driving rotor 1038 and the driven rotor are connected to the input shaft 1036 and the output shaft 1037 respectively through the second bearings 109 connected thereto.

[0183] Furthermore, the magnetic powder enters the magnetic flux working chamber through the magnetic powder gap 902. The magnetic flux working chamber is formed by the end face of the driving end of the output shaft 1037, and is enclosed by the sealing assembly 903 and the tight sealing. The sealing assembly 903 and the tight sealing are used to effectively block the magnetic powder from leaking outward, so that the magnetic powder is effectively adhered to the output shaft 1037.

[0184] Furthermore, the output shaft 1037 is connected to the cooling fan 1032 through the first bearing 108, and the cooling fan 1032 is located in the cooling system. The cooling system is fixedly installed on the outer wall of the magnetic powder clutch 103 by means of a fixing pin or the like, and the cooling system includes two sets of oppositely arranged first shells 1031 and second shells 1034, and a cooling cavity for accommodating the cooling fan 1032 is provided between the first shell 1031 and the second shell 1034.

[0185] Furthermore, the first shell 1031 and the second shell 1034 have multiple groups of first heat sinks 1033 evenly distributed along the circumference thereof, and a second heat sink 1035 adjacent to the first heat sink 1033 is arranged on one side of the first heat sink 1033, and the two groups of the second heat sinks 1035 are not adjacent to each other; the second heat sink 1035 is composed of two groups of heat dissipating fins, and a small heat sink fin is arranged between the two groups of heat dissipating fins, and heat dissipation channels with different spacings are formed by multiple groups of first heat sinks and second heat sinks.

[0186] In this embodiment, the combination of the first heat sink and the second heat sink increases the complexity of the airflow path and forms different heat dissipation channels. When the airflow flows in the heat dissipation channel, it collides with the first heat sink 1033 and the second heat sink 1035, causing the airflow to become unstable, thereby generating vortices and improving the heat dissipation effect.

[0187] In order to further improve the heat dissipation effect in practical applications, Figure 5 For further improvement on Fig.13 As shown, the first heat sink 1033 is formed by bending, so that the first heat sink 1033 has a first arc-shaped end and a second arc-shaped end, and the distances between the two ends of the first arc-shaped end and the bottom surface of the heat dissipation channel are L1 and L2 respectively, and L1 / L2=1 / 2, and the distances between the two ends of the second arc-shaped end and the bottom surface of the heat dissipation channel are L3 and L4 respectively, and L3 / L4=2 / 5, wherein L1<L2<L3<L4.

[0188] In this embodiment, since the first heat sink is formed by bending, and since the first heat sink 1033 has a first arc-shaped end and a second arc-shaped end, the airflow generates different airflow distributions according to different heights and bending degrees, so that when the airflow passes through the first heat sink, greater disturbance and irregular flow are generated, thereby enhancing the turbulence and turbulence effects of the airflow;

[0189] Since L1 / L2=1 / 2, the airflow first enters through the heat dissipation channel with a larger spacing, and L3 / L4=2 / 5, where L1<L2<L3<L4, so that more airflow passes through the heat dissipation channel with a larger spacing, and then enters the smaller spacing (L3 / L4=2 / 5), thereby increasing the flow speed of the airflow, making the airflow more impactful near the bearing position (area with higher heat), thereby improving the heat dissipation effect.

[0190] However, using only a cooling fan to dissipate heat cannot achieve the purpose of using a magnetic powder clutch, which will affect the magnetic powder by temperature, causing the magnetic permeability of the magnetic powder to change, and then causing the magnetic field to change, thus affecting the precise control of the tension. In order to further improve the heat dissipation effect, please refer to Figure 6-12 As shown, a cooler is provided in the heat dissipation system, and the cooler adopts a small cooler. The cooler is installed on the inner wall of the first shell 1031 near the position of the heat dissipation fan 1032, and the outlet end of the cooler is connected to the cooling pipe group. The cooling pipe group is arranged along the inner wall of the first shell 1031. The cooling liquid is transported to the cooling channel 1074 through the cooling pipe group. The cooling channel 1074 is arranged in a cavity formed by the driven rotor, the baffle and the end face of the output shaft 1037.

[0191] In actual application, in order to reduce the heat at the coil position, the cooling channel 1074 is set in the cavity formed by the driven rotor, the baffle and the end surface of the output shaft 1037. However, since the cooler is installed on the inner wall of the first shell 1031 near the position of the cooling fan 1032, and the cooling pipe group needs to be bent to connect to the cooling channel, there is a defect that the coolant pressure is too low, resulting in the coolant being unable to be normally transported to the cooling system. In order to solve the above defect, please refer to Figure 6-12As shown, by adding a cooling system 107 between the outlet end of the cooling pipe group and the cooling channel 1074, the cooling system 107 includes a cooling valve body 1071, the cooling valve body 1071 is fixedly installed on the inner wall of the second shell, and the outlet end of the cooling pipe group is connected to the inlet end of the cooling valve body 1071; it is convenient to transport the cooling liquid into the cooling valve body through the cooling pipe group, and the outlet end of the cooling valve body 1071 passes through the second shell and extends into the cooling channel 1074 set in the cavity formed by the driven rotor, the baffle and the end surface of the output shaft 1037; so that the outlet end of the cooling valve body is connected to the inlet end of the cooling channel 1074;

[0192] The cooling channel arranged in the cavity formed by the driven rotor, the baffle and the end face of the output shaft 1037 is connected to the cooling channel arranged in the cavity formed by the active rotor 1038, the baffle and the end face of the input shaft, and the outlet end of the cooling channel located in the cavity formed by the active rotor 1038, the baffle and the end face of the input shaft is connected to the inlet end of the cooler.

[0193] Furthermore, the cooling system 107 further includes a cam 1073 and a connecting rod 1072 coaxially fixed on the output shaft 1037, and the connecting rod 1072 is mounted on the output shaft 1037 via a second bearing 109, and the rotation of the output shaft 1037 drives the connecting rod 1072 and the cam 1073 to rotate;

[0194] The other end of the connecting rod 1072 extends into the cooling valve body 1071 of the cooling system 107 and is fixedly connected (either by a locating pin or other fixed connection methods) to the rubber seal 1078; and the rubber seal 1078, the connecting rod 1072 and the output shaft 1037 form a crank rocker mechanism. When the output shaft 1037 rotates, the cam 1073 is driven to rotate. When the raised end 1073 of the cam 1073 rotates to the top, the connecting rod 1072 drives the rubber seal 1078 to drop to the lowest point in the cooling valve body 1071 and leak out of the water inlet end, so that the coolant in the cooler can be transported to the cooling valve body 1071 through the water inlet end;

[0195] When the protruding end 1073 of the cam 1073 rotates to the bottom end, as shown in FIG. Fig.11 As shown, at this time, the connecting rod 1072 drives the rubber seal 1078 to rise to the highest point in the cooling valve body 1071, leaking out of the outlet end of the cooling valve body 1071, and using the thrust to push the coolant from the outlet end of the cooling valve body into the channel 1075, and then transported to the cooling channel 1074 through the channel 1075.

[0196] Furthermore, the distance between the water inlet end of the cooling valve body and the output shaft 1037 is smaller than the distance between the water outlet end of the cooling valve body and the output shaft 1037 .

[0197] In this embodiment, when the output shaft 1037 rotates, the cam 1073 is driven to rotate. When the raised end 1073 of the cam 1073 rotates to the top, the connecting rod 1072 drives the rubber seal 1078 to drop to the lowest point in the cooling valve body 1071 and leak out of the water inlet end. At this time, the pressure in the cooling valve body 1071 is relatively low, and the coolant is automatically sucked into the cooling valve body 1071. As the output shaft 1037 continues to rotate, the cam and the connecting rod are driven to rotate accordingly. When the raised end 1073 of the cam 1073 rotates to the bottom, as shown in FIG. Fig.11 As shown, at this time, the connecting rod 1072 drives the rubber seal 1078 to rise to the highest point in the cooling valve body 1071, leaking out of the outlet end of the cooling valve body 1071, and using the thrust to push the coolant from the outlet end of the cooling valve body into the channel 1075, and transported to the cooling channel 1074 through the channel 1075 so that the coolant in the cooler can be transported to the cooling valve body 1071 through the inlet end.

[0198] In this embodiment, in order to reduce the heat at the coil position, it is necessary to add a cooling channel in the cavity formed by the driven rotor, the baffle and the end face of the output shaft 1037. However, since the cooler is installed on the inner wall of the first shell 1031 near the position of the heat dissipation fan 1032, the cooling pipe group needs to be bent before it can connect to the cooling channel. Each time the pipe is bent, the flow resistance of the fluid will increase, which will cause the pressure of the fluid to drop, so that the cooling liquid cannot be transported to the cooling channel; and the magnetic powder is affected by the temperature, causing the magnetic permeability of the magnetic powder to change, and then causing the magnetic field to change, thereby affecting the precise control of the tension. To this end, the present invention adds a cooling system 107 between the outlet end of the cooling pipe group and the cooling channel 1074, and uses the cooling system 107 to ensure that the coolant can be transported to the cooling channel more smoothly, thereby reducing heat and improving heat dissipation performance.

[0199] In actual application, when setting up the cooling channel, due to poor sealing, the coolant in the cooling channel may enter the magnetic flux working chamber, causing the magnetic powder to agglomerate and the magnetic powder clutch to be damaged. In order to solve the above technical problems, please refer to Figure 6 , Figure 8 and Fig. 9As shown, a second sealing ring 9033 is tightly adhered to the end surface of the output shaft 1037 at the driving end position away from the input shaft 1036, and a first sealing ring 9031 is fixedly connected to the baffle at the position close to the magnetic powder gap 902 through a positioning pin 905, and the first sealing ring 9031 continuously extends along its longitudinal direction and is provided with an elastic support foot 9032 integrally provided therewith, and the elastic support foot 9032 is in conflict with the lateral end surface of the second sealing ring 9033, and the cross section of the elastic support foot 9032 continuously extending along its longitudinal direction is arranged in a wavy line shape, thereby forming a sealing end surface;

[0200] The elastic support leg 9032 continuously extends along the longitudinal direction of the first sealing ring 9031 and bends inward to form a contact end portion 9034 , and the contact end portion 9034 continuously extends until it contacts the longitudinal end surface of the second sealing ring 9033 .

[0201] Furthermore, the first sealing ring 9031 is provided with a clamping sealing end 9037 extending along the transverse direction thereof, and the clamping sealing end 9037 extends into the magnetic flux gap and is tightly attached to the end face of the driving end side of the output shaft 1037 when the first sealing ring 9031 is installed.

[0202] In this embodiment, in actual application, when the coil is energized, the magnetic powder generates a magnetic flux under the action of the coil, so that the output shaft and the input shaft are called a rigid body and rotate. Even if the legs of the first sealing ring are worn and damaged after long-term use, a small amount of cooling liquid enters through the elastic legs of the first sealing ring and will not pass through the abutment end 9034. When the output shaft rotates, it drives the first sealing ring to rotate. At this time, a small amount of cooling liquid will also slide down under the obstruction of the abutment end 9034 and be blocked by the second sealing ring 9033.

[0203] Furthermore, the tight seal includes a sealing gasket 9043, which is provided with a sealing lip 9041 extending along its transverse direction in the longitudinal direction, and the sealing lip 9041 extends into the magnetic flux gap, and when the tight seal is installed, it is tightly attached to the end face of the driving end side of the output shaft 1037.

[0204] Furthermore, an inclined sealing leg 9042 is provided on the sealing gasket 9043 near the sealing lip 9041, and the sealing leg 9042 is in contact with the other end surface of the output shaft 1037 to form a seal.

[0205] Furthermore, the working steps of the flexible material fully automatic laser printer include:

[0206] S1. First, place the material (label roll) on the unwinding mechanism 40, and manually rotate the tensioning knob of the unwinding mechanism to tighten the unwinding shaft of the unwinding mechanism 40 until the material is locked and no longer slides relative to the unwinding shaft;

At this time, the sensor in the sensing slot senses the material, and the sensor indicator light goes out;

[0210] Then, it passes through the gap between the pressure roller and the support roller arranged at the outlet end of the feeding mechanism, and enters the shearing mechanism through the inlet of the shearing mechanism 70;

[0211] Finally, the material passes through the shearing machine, and the blank (without printing end) of the material is wound on the winding disk 1021 of the winding mechanism 10, and then the tensioning knob of the winding mechanism is manually rotated to tighten the winding shaft of the winding mechanism until it is locked, and then the positioning disk is installed and locked by the quick locking mechanism;

[0212] S5. Pull the end of the material so that the material is parallel to the feeding path; then bend the wrench and pull the wrench back to the outside (at this time, the positioning column extends into the positioning groove of the wrench), so that the two sets of rollers are in a compacting state, and the two sets of rollers are used to compact the material;

[0213] S7. First, confirm that the laser printer switch button is turned on, the indicator light is on, set the corresponding parameters, select the print pattern, and make adjustments; press the switch to start marking until the target is met;

If cutting is to be carried out, press the left and right adjustment button on the panel to adjust the left and right positions of the scissors of the cutting mechanism so that the cutting position of the scissors is just in the middle of the two marked contents. After the left and right positions of the cutting mechanism are confirmed, press the switch of the cutting mechanism to cut;

[0215] If shearing is not required, the material is wound around the winding mechanism through the shearing mechanism.

[0216] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention is described in detail with reference to the embodiments, it should be understood by those skilled in the art that any modification or equivalent replacement of the technical solutions of the present invention does not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
