[0037] After label printing, winding is usually needed for subsequent label applicator use. In order to avoid uneven ends caused by label slack during winding, a compression roller is arranged in some label winding equipment. During work, the compression roller extrudes the label towards one direction to make the label tight, so that the label is more neatly wound on the winding drum. Then, due to the extrusion of the compression roller, a certain pulling force is formed on the label, which is easy to cause the label to slide during label printing, and thus the label printing quality is low.

[0038] Based on the above problems, the utility model embodiment provides a label winding machine which can be used for winding the printed label and improving the label printing quality. Referring to Figure 1 , Figure 1 The utility model embodiment first kind of label winding machine's structure schematic diagram is provided. The label winding machine of this embodiment comprises a support 100, a winding mechanism and a compression wheel mechanism 200, the winding mechanism comprises a first driving part and a winding roller 300, the first driving part is for example motor, air cylinder or hydraulic cylinder etc., the first driving part is connected with the winding roller 300, and is used for driving the winding roller 300 to rotate. Specifically, for example, the first driving part is a motor, and the motor is connected to the winding roller 300 through a shaft coupling, a gear or a belt, and is used to drive the winding roller 300 to rotate. When the first driving part is an air cylinder, the air cylinder and the winding roller 300 are connected through a rack and pinion transmission, so that the extension and contraction of the air cylinder is converted into the rotation of the winding roller 300. The winding roller 300 is used for mounting a winding drum, and the winding drum is used for winding the label. The compression wheel mechanism 200 is located upstream of the winding roller 300, and the compression wheel mechanism 200 comprises a first compression wheel shaft 210 and a second compression wheel shaft 220. The first compression wheel shaft 210 and the second compression wheel shaft 220 are both rotatably connected to the support 100, and the first compression wheel shaft 210 and the second compression wheel shaft 220 are spaced apart to form a material passing gap 230. The material passing gap 230 is used for the label to pass through, so that the label is clamped between the first compression wheel shaft 210 and the second compression wheel shaft 220. Specifically, during winding, the label passes through the material passing gap 230 and is clamped between the first compression wheel shaft 210 and the second compression wheel shaft 220. Thus, when the winding roller 300 drives the winding drum to rotate to wind the label on the surface of the winding drum, the winding drum will form a certain pulling force on the label to make the label tight, thereby avoiding unevenness caused by label slack, and improving the quality of label winding. Moreover, since the compression wheel mechanism is located upstream of the winding mechanism, the compression wheel mechanism 200 is located between the winding roller 300 and the printer during use. Therefore, the compression wheel mechanism 200 can effectively prevent the pulling force formed by the winding roller 300 on the label from being directly transmitted to the printing device, thereby effectively reducing the risk of label sliding in the printing device, and improving the label printing quality.

[0039] In some embodiments of the utility model, first pressure wheel shaft 210 and second pressure wheel shaft 220 can be relatively moved to adjust the size of the gap 230, so that first pressure wheel shaft 210 and second pressure wheel shaft 220 can clamp labels of different thicknesses, to improve the practicability of the label winding machine of the embodiment. Specifically, for example, first pressure wheel shaft 210 is movably connected to support 100, and / or first pressure wheel shaft 210 is movably connected to support 100, so that when winding labels of different thicknesses by the label winding machine of the embodiment, the distance between first pressure wheel shaft 210 and second pressure wheel shaft 220 can be adjusted to adapt to labels of different thicknesses, thereby improving the practicability of the label winding machine of the embodiment. Specifically, for example, the pressure wheel mechanism 200 further comprises a second driving member and a first connecting member, the first pressure wheel shaft 210 is rotatably connected to the first connecting member, the second driving member is connected to the support 100 and connected with the first connecting member, for driving first pressure wheel shaft 210 to move towards or away from second pressure wheel shaft 220, so that when winding labels of different thicknesses by the label winding machine of the embodiment, the user can adjust the distance between first pressure wheel shaft 210 and second pressure wheel shaft 220, i.e. the size of the gap 230, so that the label winding machine of the embodiment can be applied to more kinds of labels, to improve the practicability of the label winding machine of the embodiment. Alternatively, in some embodiments, the pressure wheel mechanism 200 further comprises a third driving member and a second connecting member, the second pressure wheel shaft 220 is rotatably connected to the second connecting member, and the third driving member is connected to the support 100 and connected with the second connecting member.

[0040] In addition, in some embodiments, first pressure wheel shaft 210 is slidably connected to support 100 through a slide rail or a slide groove, and the pressure wheel mechanism 200 further comprises a first fastener for locking first pressure wheel shaft 210 to support 100, so that the user can manually adjust the distance between first pressure wheel shaft 210 and second pressure wheel shaft 220 during use. Similarly, in some embodiments, second pressure wheel shaft 220 is movably connected to support 100 through a slide rail or a slide groove, and the pressure wheel mechanism 200 further comprises a second fastener for locking second pressure wheel shaft 220 to support 100.

[0041] On the basis of the above embodiment, the pressure wheel mechanism 200 further comprises an elastic member, and the elastic member makes the first pressure wheel shaft 210 or the second pressure wheel shaft 220 float. Specifically, taking the first pressure wheel shaft 210 as an example, the pressure wheel mechanism as described in the above embodiment further comprises a first connecting member, and the elastic member, for example, is a compression spring or a tensile spring or any other structure with elasticity, one end of the elastic member is connected to the first connecting member, and the other end of the elastic member is connected to the first pressure wheel shaft 210. Therefore, when the distance between the first pressure wheel shaft 210 and the second pressure wheel shaft 220 is adjusted, the initial size of the material passing gap 230 is smaller than the thickness of the label, and when the label passes through the material passing gap 230, the label will separate the first pressure wheel shaft 210 and the second pressure wheel shaft 220, and the corresponding elastic member will exert an elastic force on the first pressure wheel shaft 210 towards the label, so that the label is clamped between the first pressure wheel shaft 210 and the second pressure wheel shaft 220, thereby avoiding damage to the label while providing sufficient pressure.

[0042] With reference to Figure 2 , Figure 2 Fig. 2 is a structural schematic view of a second label winding machine according to an embodiment of the present application, and in some embodiments of the present application, the label winding machine further comprises a tension control mechanism 400, and the tension control mechanism 400 is located upstream of the pressure wheel mechanism 200. The tension control mechanism 400 comprises a plurality of control rollers, and the plurality of control rollers are arranged such that when the label passes through the gap between adjacent control rollers, the wrap angle between the label and each control roller is greater than 0. For example, the tension control mechanism 400 comprises three control rollers, and the three control rollers are spaced apart along a direction. When working, the label passes through the gap between adjacent control rollers, so that the label is bent in the three control rollers during the label conveying process, thereby increasing the acting force between the label and the control rollers, so as to form a certain resistance to the conveying of the label. Correspondingly, the tension control mechanism 400 will form a certain resistance to the transmission of the pulling force of the label formed by the winding roller 300 to the printer, thereby further hindering the transmission of the pulling force of the label formed by the winding roller 300 to the printer, and further improving the label printing quality.

[0043] With reference to Figure 2 On the basis of the above embodiment, among the plurality of control rollers, a part of the control rollers are fixedly connected to the support 100, and the other part of the control rollers are rotatably connected to the support 100. For the convenience of description, the control rollers fixedly connected to the support 100 are referred to as first control rollers 410, and the control rollers rotatably connected to the support 100 are referred to as second control rollers 420. Taking the first control roller 410 as an example, the first control roller 410 is fixedly connected to the support 100, and the first control roller 410 is arranged to be rotatable relative to the support 100. When working, the label passes through the gap between adjacent control rollers, so that the label is bent in the control rollers during the label conveying process, thereby increasing the acting force between the label and the control rollers, so as to form a certain resistance to the conveying of the label. Correspondingly, the tension control mechanism 400 will form a certain resistance to the transmission of the pulling force of the label formed by the winding roller 300 to the printer, thereby further hindering the transmission of the pulling force of the label formed by the winding roller 300 to the printer, and further improving the label printing quality. Figure 2As shown, the tension control mechanism 400 includes four control rollers, two first control rollers 410 and two second control rollers 420, the first control rollers 410 and the second control rollers 420 are arranged alternately, therefore, during the movement of the label, the label is adjusted by the sliding friction of the first control rollers 410 and the rolling of the second control rollers 420, so as to adjust the pulling force of the winding roller 300 on the label during the winding process, that is, to adjust the tension of the label, so that the label is wound on the winding drum more neatly, and the label is not damaged due to excessive pulling force.

[0044] With reference to Figure 3 , Figure 3 It is a structural schematic view of a third label winding machine according to the present application, in some embodiments of the present application, the control roller fixedly connected to the support 100 is the first control roller 410, and the label winding machine further includes an end face flattening mechanism 500, the end face flattening mechanism 500 includes a first flattening piece 510 and a second flattening piece 520, the first flattening piece 510 and the second flattening piece 520 are connected to the first control roller 410 along the axial direction of the first control roller 410, and the first flattening piece 510 and the second flattening piece 520 are respectively used for abutting against both sides of the label to limit the movement of the label along the axial direction of the first control roller 410. Specifically, during the winding process, the label is arranged between the first flattening piece 510 and the second flattening piece 520, and the first flattening piece 510 and the second flattening piece 520 abut against both sides of the label, specifically, both sides in the width direction, so as to prevent the label from moving along the length direction of the first control roller 410 during the conveying process, and further make the label wind on the winding drum more neatly.

[0045] It should be noted that the end face flattening mechanism 500 is connected to the first control roller 410 in the present embodiment, which cannot be interpreted as that the first flattening piece 510 and the second flattening piece 520 are connected to each first control roller 410, as long as at least one of them is connected with the end face flattening mechanism 500, and according to the actual demand, the end face flattening mechanism 500 can be connected to each first control roller 410.

[0046] With reference to Figure 4 , Figure 4The utility model discloses a fourth kind of label winding machine's structure schematic diagram of embodiment of the utility model, on the basis of above -mentioned embodiment, end face flattening mechanism 500 still includes first locking piece 530, and first flattening piece 510 is movably connected in first control roll 410, and first locking piece 530 is used for locking first flattening piece 510. Specifically, for example, first flattening piece 510 is set up in the outside of first control roll 410, and first flattening piece 510 has the threaded hole of going through, and first locking piece 530 has the external thread, when using, unscrews first locking piece 530, and first flattening piece 510 is moved to the appropriate position along the axial direction of first control roll 410, to make the distance between first flattening piece 510 and second flattening piece 520 adapt the width of label, and then tightens first locking piece 530, and first locking piece 530 is pressed against first control roll 410, thereby locking first flattening piece 510 on first control roll 410, thereby make end face flattening mechanism 500 can adapt the spacing of the label of different width, thereby improve the practicality of label winding machine of this embodiment.

[0047] It needs to be explained that the distance between the first flattening piece 510 and the second flattening piece 520 is adapted to the width of the label, and is not limited to the distance between the first flattening piece 510 and the second flattening piece 520 being equal to the width of the label. It can also be slightly larger than the width of the label.

[0048] Similarly, in some embodiments of the utility model, the end face flattening mechanism 500 further comprises a second locking piece 540, the second flattening piece 520 is movably connected to the first control roll 410, and the second locking piece 540 is used for locking the second flattening piece 520, which will not be repeated here.

[0049] It can be understood that whether the first flattening piece 510 position is adjustable or the second flattening piece 520 position is adjustable, adjustment needs to be based on the other as a reference, so the position of the label in the axial direction of the first control roll 410 is limited, and correspondingly, in order to wind the label in the middle position of the roll material cylinder, the size of the roll material cylinder is limited. Based on this, in some embodiments of the utility model, the positions of the first flattening piece 510 and the second flattening piece 520 are adjustable. Specifically, the end face flattening mechanism 500 further comprises a first locking piece 530 and a second locking piece 540, the first flattening piece 510 is movably connected to the first control roll 410, the first locking piece 530 is used for locking the first flattening piece 510, the second flattening piece 520 is movably connected to the first control roll 410, and the second locking piece 540 is used for locking the second flattening piece 520. Thus, the positions of the first flattening piece 510 and the second flattening piece 520 can be adjusted simultaneously according to the requirements during use, so as to adjust the position of the label in the axial direction of the first control roll 410, so that the label is wound in the middle position of the roll material cylinder, thereby improving the practicality of the label winding machine of this embodiment.

[0050] In some embodiments of the utility model, the label winding machine further includes a controller and a sensor, the sensor is connected to the support 100, and is used for detecting the tension degree of the label, the sensor and the first driving member are both in communication connection with the controller, and the controller is configured to: when the sensor detects that the tension of the label is greater than a set value, the detection signal of the sensor changes, and the signal is sent to the controller, and the controller reduces the rotating speed of the winding roller by the first driving member. Specifically, the sensor can be a force sensor or a position sensor, for example, when the sensor is a force sensor, the force sensor is in contact with the label directly or indirectly through other components during the winding process, and is used for detecting the tension of the label. When the sensor is a position sensor, the position sensor is arranged above or below the label conveying path, and it can be understood that the label will naturally sag under the action of gravity, and the sagging degree is different under different tensions, so that the tension of the label can be indirectly detected by detecting the sagging degree of the label by the position sensor, for example, when the label sagging amount is large, it represents that the rotating speed of the winding roller 300 cannot keep up with the printing speed of the printer, at this time, the position sensor transmits the signal to the controller, the controller controls the first driving member to speed up, thereby improving the winding speed of the label, and further avoiding the abrasion of the label caused by the label contacting the ground due to excessive sagging. Correspondingly, when the label is directly straightened, it represents that the rotating speed of the winding roller 300 is too fast, and the winding speed cannot keep up with the printing speed of the printer, at this time, the controller controls the first driving member to slow down or stop, thereby avoiding the label from being torn.

[0051] It should be noted that the control program used by the label winding machine of the embodiment is a conventional program in the art, and can be easily obtained by those skilled in the art.

[0052] Referring to Figure 5 , Figure 5In some embodiments of the present application, the label winding machine further comprises a reverse winding mechanism, and the reverse winding mechanism comprises a reverse winding roller 600, which is used for mounting the winding material cylinder. Specifically, because the printing direction of the printer and the up-down and left-right directions of the label content are relatively fixed, the direction of the label after being directly wound back after printing is opposite to the direction of the label when being pasted, and therefore, the label needs to be wound back again in actual use to adjust the direction of the label. Therefore, in some technologies, after the label is wound, the winding material cylinder needs to be disassembled and delivered to other equipment to adjust the direction, which reduces the label winding efficiency. However, the present embodiment can effectively improve this problem. In the present embodiment, the reverse winding mechanism further comprises a reverse winding roller 600, and after the winding roller 300 completes winding of the label, the reverse winding roller 600 can be directly used to wind back the label, thereby improving the work efficiency. Specifically, for example, the reverse winding roller 600 is a non-powered roller, and in use, the winding material cylinder with the label wound thereon is disassembled from the winding roller 300 and mounted on the reverse winding roller 600, the empty winding material cylinder is mounted on the winding roller 300, the label is pulled from the reverse winding roller 600 to the winding roller 300, and finally the first driving member is used to drive the winding roller 300 to rotate, thereby completing the reverse winding of the label. Further, in some embodiments, the reverse winding mechanism further comprises a fourth driving member connected to the reverse winding roller 600 and used for driving the reverse winding roller 600 to rotate, and therefore, after the winding roller 300 completes winding, the label can be directly pulled to the reverse winding roller 600 for reverse winding, thereby improving the work efficiency.

[0053] Further, the pressure roller mechanism 200 and the tension control mechanism 400 are located between the reverse winding roller 600 and the winding roller 300, and therefore, when the label is wound back, the tension of the label can be adjusted by the pressure roller mechanism 200 and the tension control mechanism 400, so that the label can be wound on the winding material cylinder in an orderly manner.

[0054] In some embodiments of the present application, the winding roller 300 is an air inflation roller, when it is necessary to fix the winding material cylinder, the user inflates the air inflation shaft, after inflation, the pressure in the air inflation shaft increases, and the keys on the surface of the shaft expand outward, thereby pressing and fixing the external winding material cylinder. When it is necessary to release the winding material cylinder, the user only needs to press the slide valve on the air nozzle with the hand, so that the gas in the air inflation shaft is rapidly discharged. With the discharge of the gas, the keys rapidly retract, thereby releasing the locking of the winding material cylinder, thereby realizing the rapid mounting and disassembly of the winding material cylinder, and further improving the work efficiency. Similarly, in some embodiments of the present application, the reverse winding roller 600 is an air inflation roller, which will not be described herein again.

[0055] Reference Figure 5In some embodiments of the present application, the label winding machine further comprises an emergency stop switch 700, the emergency stop switch 700 is electrically connected with the first driving member, and is used for switching the start and stop of the first driving member.

[0056] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range of the ordinary skill in the art without departing from the purpose of the present application.
