[0024] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] As attached Figure 1 As shown, the present invention provides an automatic labeling device for labeling cleaning cloth rolls. The entire device is controlled by a controller and includes a chassis 1 and a support platform 2 installed on one side of the chassis 1, which together constitute a frame.

[0026] A conveyor belt 4 is fixedly mounted on the support platform 2 , and the conveyor belt 4 is provided with side guardrails for ensuring that the cleaning cloth roll of the material is always in a vertical state and is conveyed by the conveyor belt 4 .

[0027] A rolling aid module 3 is provided on the support platform 2 located on one side of the conveyor belt 4, and a rotatable adsorption module 6 and a paper feeding module 7 are installed on the top of the chassis 1, wherein the adsorption module 6 is located on the side of the conveyor belt 4 away from the rolling aid module 3 and is opposite to the rolling aid module 3; the paper feeding module 7 is located on the side of the adsorption module 6 away from the conveyor belt 4, and is used to provide label paper to the adsorption module 6.

[0028] The side guardrail of the conveyor belt 4 is provided with notches matching the auxiliary winding module 3 and the adsorption module 6; the conveyor belt 4 is also equipped with a positioning module 5, which is located between the auxiliary winding module 3 and the adsorption module 6, and is used to limit the material that reaches between the auxiliary winding module 3 and the adsorption module 6 to prevent it from continuing to move downstream along the conveyor belt 4.

[0029] A fan 8 and a drive motor 9 are installed inside the chassis 1 . The drive motor 9 is used to drive the adsorption module 6 and the paper feeding module 7 .

[0030] During use, the label paper is loaded on the paper feeding module 7, and the colloid is sprayed on the label paper; the positioning module 5 limits the position of the material, the adsorption module 6 adsorbs the label paper coated with glue, and then the auxiliary rolling module 3 is started, the material is driven to rotate by friction, and then the adsorption module 6 is cooperated to transfer the label paper to the material and stick it tightly. When the auxiliary rolling module 3 is started, it will cooperate with the adsorption module 6 to squeeze the material. After the label is attached, the auxiliary rolling module 3 returns to its position, and the material tensions the label through its own elasticity.

[0031] The structure of the positioning module 5 is shown in the attached Figure 1 and attached Figure 2 , including a first gantry 51 and a fourth cylinder 52, wherein the first gantry 51 is obliquely across the conveyor belt 4, and the space between the two columns of the first gantry 51 corresponds to the notch on the side guardrail. The fourth cylinder 52 is fixedly installed at the bottom of the crossbeam of the first gantry 51, and the output end is vertically downward, and a top plate 53 that can rotate freely along the axis is installed at the output end of the fourth cylinder 52.

[0033] A fifth cylinder 74 is fixedly mounted on one end of the third slide plate 73 away from the adsorption module 6, the axis of the fifth cylinder 74 is horizontal, and the output end is fixedly connected to the third bottom plate 739, so that the third slide plate 73 is driven away from or close to the adsorption module 6 by the extension and contraction of the output end of the fifth cylinder 74. When it is not necessary to write a label, the output end of the fifth cylinder 74 is in an extended state.

[0034] In order to ensure the smoothness of the movement of the third slide plate 73, a first spring seat 737 is fixedly installed on the end of the third slide plate 73 away from the fifth cylinder 74, a second spring seat is fixedly installed on the end of the third base plate 739 away from the fifth cylinder 74, and a fourth spring 738 is installed between the first spring seat 737 and the second spring seat. Specifically, hooks are provided at both ends of the fourth spring 738, and the hooks are respectively hung on the first spring seat 737 and the second spring seat.

[0070] In order to more conveniently transfer the label paper on the label removal drum to the label suction drum, and to stick the label paper on the label suction drum to the material, the suction module 6 also includes two paddle groups 621, and two groups of arc-shaped paddles are installed on the paddle groups 621, and the two groups of paddles are respectively located in the corresponding first annular groove 635 and second annular groove 639. When the label paper on the label removal drum rotates to the corresponding group of paddles, it is picked up by the corresponding paddles, and approaches the label suction drum along the arc of the paddles, and then is smoothly adsorbed to the label suction drum. As the label suction drum rotates, the end of the label paper meets the other group of paddles again and is picked up, and then the label paper approaches the material along the arc of the paddles, and is attached to the material with the cooperation of the auxiliary winding module 3. That is, this paddle group 621 plays a guiding role in the transfer of the label paper.

[0071] As attached Fig. 20 As shown, the paddle assembly 621 includes a first paddle assembly and a second paddle assembly. The first paddle assembly includes a first connecting column 640, on which a plurality of arc-shaped first paddles 642 are fixedly mounted in a linear array in sequence along the length direction thereof, and the ends of the first paddles 642 are located in the corresponding second annular groove 639.

A second stopper 649 is sleeved on the second connecting column 647 between two adjacent second paddles 648 to locate the position of the second paddles 648.

[0073] The bottom of the first connecting column 640 is fixedly inserted in the first connecting sleeve 643, and of course it can also be connected by other methods such as threaded installation; the first connecting sleeve 643 is fixedly connected to the positioning ring 645 through the first support arm 644; the bottom of the second connecting column 647 is installed in the second connecting sleeve 646, and the installation method is the same as the connection method between the first connecting column 640 and the first connecting sleeve 643.

[0074] As attached Fig.24 As shown, the interior of the fourth rotating shaft 620 is provided with a first large diameter section 650 and a first small diameter section 651 which are interconnected from top to bottom, the first small diameter section 651 is connected to the first groove 624, and the diameter of the first groove 624 is larger than the diameter of the first small diameter section 651. Due to the existence of the first small diameter section 651, when the fan 8 sucks air, the airflow is accelerated in the first small diameter section 651, which is beneficial to the discharge of the gas in the first adsorption cylinder 61 and the stability of the negative pressure. The aforementioned first air hole 623 is arranged in the first large diameter section 650.

[0075] As attached Fig.25 As shown, the first rotating shaft 69 is provided with a second large diameter section 652 and a second small diameter section 653 which are connected to each other from top to bottom, the second small diameter section 653 is connected to the second groove 630, the diameter of the second groove 630 is larger than the diameter of the second small diameter section 653, and the principle of this design is the same as that of the fourth rotating shaft 620.

[0076] A second flange 631 matching the second groove 630 is fixed on the top of the second rotating shaft 613 .

[0077] Of course, the second rotating shaft 613 in the above embodiment can be equipped with a fourth gear meshing with the third gear as in the prior art.

[0078] The structure of the winding module 3 is shown in the attached figure. Fig.21 The present invention comprises a first base plate 31 fixedly mounted on the support platform 2 through a first support column 21, a first guide rail 32 consistent with the length direction of the first base plate 31 is mounted on the top, and a first slide plate 33 is slidably mounted on the first guide rail 32; a cylinder seat 34 is fixedly mounted on the top of the first end of the first base plate 31, that is, the top of the end away from the conveyor belt 4, and the cylinder seat 34 is perpendicular to the first base plate 31, and a horizontal first cylinder 35 is fixedly mounted on the cylinder seat 34, and the output end of the first cylinder 35 passes through the cylinder seat 34 and is fixedly connected to the first slide plate 33, so that the first slide plate 33 is pushed close to or away from the conveyor belt 4 by the first cylinder 35.

[0079] A first limiting plate 36 is fixedly mounted on the top of the first end of the first slide plate 33 , i.e., the top of one end close to the first cylinder 35 . The length direction of the first limiting plate 36 is perpendicular to the length direction of the first slide plate 33 , and the first limiting plate 36 is perpendicular to the first slide plate 33 .

[0080] Both ends of the first limit plate 36 are installed with guide rods 38 through first bolts 37, that is, the first bolts 37 pass through the first limit plate 36 and are screwed to the internal threaded screw holes at one end of the guide rods 38. The two guide rods 38 are arranged horizontally and parallel to each other, and the length direction is consistent with the length direction of the first slide plate 33; the other end of the guide rod 38 is inserted into the limit seat 327 and fixed by a top screw or a bolt.

[0081] The two guide rods 38 are respectively slidably matched with the two ends of the second slide plate 39. A first spring 328 is sleeved on each guide rod 38, and the two ends of the first spring 328 are respectively abutted against the second slide plate 39 and the limit seat 327.

[0082] The top of the second slide plate 39 is detachably mounted with two parallel vertical plates 311 via hexagon socket bolts. The tops of the two vertical plates 311 are respectively connected to the two ends of the top plate via hexagon socket bolts. The top plate is parallel to the second slide plate 39, so that the vertical plates 311 and the top plate form another gantry structure.

[0083] like Fig.21 and attached Figure 2 As shown, an active roller 315 is rotatably installed between the second slide plate 39 and the top, and the active roller 315 is drivingly connected to a belt motor 329 fixedly installed at the bottom of the first slide plate 33 .

[0084] The first bottom plate 31 is provided with an avoidance hole 330 matching the belt motor 329 .

[0085] On both sides of the second end of the first slide plate 33, that is, on both sides of the end away from the first cylinder 35, there are respectively fixedly installed a vertical first roller seat 317 and a second roller seat 322, the first roller seat 317 is installed with a vertical first guide roller 319, and the second roller seat 322 is installed with a vertical second guide roller, and the two guide rollers are on the same straight line; a belt 316 is sleeved between the first guide roller 319, the second guide roller and the active roller 315, and the belt 316 is as shown in the attached Fig.21 As shown, it is in an isosceles triangle state, and its straight side is parallel to the conveyor belt 4.

[0086] A first oblong hole 314 is provided on the top plate. The first oblong hole 314 is located on a side of the active roller 315 close to the first cylinder 35 and is located on the same straight line as the first cylinder 35 . The length direction of the first oblong hole 314 is consistent with the length direction of the first slide plate 33 .

[0087] The second slide plate 39 is provided with a fourth oblong hole matching the first oblong hole 314, a central shaft 331 is installed between the first oblong hole 314 and the fourth oblong hole, and a pressing roller 312 is rotatably installed on the central shaft 331. A first pressing bolt 310 is installed on the second slide plate 39 through an internal thread through hole, and the first pressing bolt 310 extends into the fourth oblong hole to press the central shaft 331, and a second pressing bolt 313 is installed on the top plate through an internal thread through hole, and the second pressing bolt 313 extends into the first oblong hole 314 to press the central shaft 331.

[0088] The belt 316 is located between the pressure roller 312 and the driving roller 315 , that is, the belt 316 is clamped by the pressure roller 312 and the driving roller 315 , so that the belt 316 will not deviate during the operation of the equipment.

[0089] A second avoidance groove matching the material is provided on the second slide plate 39 located between the first roller seat 317 and the second roller seat 322 .

[0090] When labeling, the output end of the first cylinder 35 is extended, so that the belt 316 is close to the material. Since the material is fixed by the positioning module 5 and the adsorption module 6, the belt 316 will be squeezed by the material and concave toward the active roller 315, so that the belt 316 forms a semi-enclosed structure for the material. Due to the existence of the first spring 328, the active roller 315 will always have a tendency to move away from the limit seat 327, so the belt 316 is always tight. The belt motor 329 drives the belt 316 to rotate, and then drives the material and the label suction drum to rotate through friction. After the label paper on the label suction drum is picked up by the corresponding paddle, it approaches the material along the paddle, and then is rolled between the material and the belt 316 by the belt 316, and the end of the label paper that is coated with glue is rolled in first. Finally, the glued end of the label paper adheres to the uncoated end, preventing the glue from adhering to the material.

[0091] Since the material is made of cloth, it will shrink toward the center under the pressure of the belt 316 and the label suction drum. After the label is attached, that is, after the belt motor 329 rotates a predetermined number of times, the output end of the first cylinder 35 shrinks, the belt 316 recovers, and the material also recovers, thereby making the label paper taut.

[0092] When one material is being labeled, other materials will move forward on the conveyor belt 4, affecting normal labeling; therefore, an extension plate is provided at the second end of the first bottom plate 31 and toward the incoming material side, on which a horizontal second cylinder 325 and a third cylinder 326 are mounted, with a gap between them, and both output ends face the conveyor belt 4; a first baffle 323 is fixedly mounted at the output end of the second cylinder 325, and a second baffle 324 is fixedly mounted at the output end of the third cylinder 326, with at least a material diameter distance between the second baffle 324 and the first baffle 323.

[0093] A sensor bracket 318 is also fixedly mounted on the extension plate, and the top of the sensor bracket 318 is higher than the top of the first roller seat 317. A first sensor 320 and a second sensor 321 are mounted on the top of the sensor bracket 318, and the second sensor 321 is located between the first baffle 323 and the second baffle 324, and the first sensor 320 is located between the first roller seat 317 and the second roller seat 322.

[0094] When the first sensor 320 detects the presence of material, the drive motor 9, the belt motor 329, the first cylinder 35, the fifth cylinder 74, etc. start to operate and perform labeling operations; at this time, the second cylinder 325 pushes the first baffle 323 to extend to block the subsequent material. If the second sensor 321 detects material at this time, the second baffle 324 extends. When the labeling of the first material is completed, that is, when the first sensor 320 cannot detect the material, the first baffle 323 and the second baffle 324 retract in sequence.

[0095] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
