A pulling assembly 6 for pulling the bottom paper on the sheet material is arranged on the frame 1 and below the label stripping assembly 3. The pulling assembly 6 can move away from or approach the label stripping assembly 3 in the height direction of the frame 1. At the same time, a housing 8 is arranged outside the frame 1 and on both sides of the length direction of the frame 1 and on the end side of the end where the label stripping assembly 2 is located, which plays a protective role; and the frame 1 has a bottom paper outlet 9 at the end side where the feeding assembly 5 is located, so as to facilitate the discharge of the bottom paper after the sheet material is stripped; observation ports 81 are opened on the housing 8 on both sides of the length direction of the frame 1, through which the movement of the pulling assembly 6 can be observed. In this way, the sheets are stacked on the feeding component 5, and the label discharging component 2 is moved to a certain distance away from the label stripping component 3. A sheet of sheet is sent to the label stripping component 3 by the feeding component 5, and the pulling component is activated at the same time to rise between the label discharging component 2 and the label stripping component 3 to clamp the base paper on the sheet. Then the pulling component is lowered, and the label discharging component 2 is activated at the same time to approach the label stripping component 3. The label on the sheet is stripped off to the label discharging component 2 by the simultaneous action of the label stripping component 3 and the pulling component 6, and the stripping of the label on a sheet is completed. Finally, the base paper is discharged and the action before the cycle is completed.

[0038] like Figure 4As shown, the labeling assembly 2 in this example is composed of a base 21, a first buffer 22, a push rod 23, a slide 24, an adjusting screw 25, an optical fiber 26, and a labeling table 27, wherein: the base 21 is mounted on the frame 1 through the slide 24, and is driven by the push rod 23 arranged on the base 21, so that the labeling assembly 2 can move relative to the label stripping assembly 3; and the base 21 is connected with an optical fiber 26 through the adjusting screw 25, and the optical fiber 26 is used to adapt to labels of different specifications; a labeling table 27 is provided on the base 21 and above the optical fiber 26, and the labeling table 27 is a non-stick table surface, which is conducive to labeling; a first buffer 22 is also provided on the base 21, and the first buffer 22 adopts a spring or a rubber pad to play a buffering role during the movement of the base; the push rod 23 can adopt a cylinder, which has the advantages of fast response and convenient automatic control. Of course, a hydraulic cylinder, an electro-hydraulic cylinder or a linear motor can also be adopted to achieve the same purpose.

[0039] like Figure 5 As shown, the label stripping assembly 3 in this example is composed of a label stripping table 31, a stripping knife 32, a cover plate 33, a second buffer 34, a top block 35, a guide plate 36, and a slide rail 37, wherein: the label stripping table 31 is installed on the frame 1, and is provided with a fixed stripping knife 32 and a movable cover plate 33, and the cover plate 33 is located above the stripping knife 32; the guide plate 36 is installed on the label stripping table 31 through the slide rail 37, and is provided with a top block 35 that cooperates with the pulling assembly 6 and a second buffer 34 that acts on the cover plate 33, that is, when the pulling assembly 6 moves upward, it will support the top block 35 and The guide plate 36 is pushed to slide on the slide rail 37, so that the cover plate 33 hinged on the label stripping table 31 is opened through the second buffer member 34 on the guide plate 36, so that the sheet delivered by the feeding assembly 5 can smoothly and conveniently enter the label stripping assembly 3, that is, the sheet is between the cover plate 33 and the stripping knife 32, and then after the pulling assembly 6 clamps the backing paper on the sheet and moves downward, the cover plate 33 loses the function of the top block 35 and slowly descends and covers the sheet under the action of the second buffer member 34, so that the stripping knife 32 can cooperate with the pulling assembly 6 to complete the stripping of the label on the sheet. The second buffer member 34 can be a spring or a rubber pad.

[0040] like Figure 6-8As shown, the feeding assembly 5 in this example is composed of a material plate 51, a baffle plate 52, a second motor 53, a synchronous belt 54, a synchronous wheel 55, a feeding belt 56, a transfer wheel 57, a transfer belt 58, and a feeding wheel 59, wherein: the material plate 51 is installed on the frame 1, and three baffle plates 52 are arranged above it in a π-shaped distribution to form a drop bin for stacking sheets, and the two parallel baffle plates can be adjusted to be close to and away from each other to adapt to sheets of different specified sizes; the second motor 53, the synchronous wheel 55 connected to the second motor 53 through the synchronous belt 54, the transfer wheel 57 connected to the feeding belt 56 and the synchronous wheel 55, and the feeding wheel 59 connected to the transfer wheel 57 through the transfer belt 58 are arranged below the material plate 51, and the feeding wheel 59 is arranged close to the second motor 53, and the synchronous wheel 55 is arranged close to the label stripping assembly 3. The transfer wheel 57 is arranged between the feeding wheel 59 and the synchronous wheel 55, and the synchronous belt 54 and the feeding wheel 59 are exposed above the material plate 51. In this way, the synchronous belt 54 is driven to rotate by the second motor 53 to drive the synchronous wheel 55 to rotate, and the synchronous wheel 55 and the transfer wheel 57 are connected by the feeding belt 56, which drives the feeding belt 56 to rotate, so that the sheet material can be conveyed on the material plate 51 by the feeding belt 56. At the same time, the feeding wheel 59 is also connected to the transfer wheel 57 by the transfer belt 58, that is, the feeding wheel 59 will also rotate therewith, so as to assist the sheet material to be conveyed on the material plate 51 by the feeding wheel 59. In short, the second motor 53 drives the feeding belt 56 and the feeding wheel 59 to complete the conveying of the sheet material on the material plate 51 to the label stripping component 3. Through the cooperation of the two, its conveying capacity is fast and effective.

[0041] In this example, a handle 10 is provided on both sides of the extending direction of the material plate 51. The label stripping machine can be lifted and pulled by the handle 10, so that it is convenient and reliable to operate, install and carry.

[0042] like Fig. 9 As shown, a check assembly 4 for preventing the sheet from being fed back is provided on the frame 1 in this example and located above the feeding belt 56. The check assembly 4 is composed of a bracket 41, a first motor 42, a check valve 43, and an arc-shaped pressure plate 44. The bracket 41 is mounted on the frame 1, on which a first motor 42 and an arc-shaped pressure plate 44 are provided. The first motor 42 is provided with a check valve 43 in contact with the sheet. Through the cooperation of the check valve 43 and the arc-shaped pressure plate 44, it can be ensured that a single sheet coming out of the feeding assembly 5 can be conveyed to the label stripping assembly 3 without returning to the feeding assembly 5.

[0043] like Fig.10As shown, the pulling assembly 6 in this example is composed of a base 61, an upper clamping plate 62, a lower clamping plate 63, a guide rail 65, a rack 66, a third motor 67, a fourth motor 68, and a gear mechanism 69, wherein: the guide rail 65 and the rack 66 are arranged in parallel and installed on the frame 1, the base 61 is slidably matched with the guide rail 65 and meshes with the rack 66 through the third motor 67 and the gear teeth (not shown) thereon, that is, through the drive of the third motor 67 and under the cooperation of the rack 66 and the guide rail 65, the base 61 can be moved up and down along the guide rail 65, so that the pulling assembly 6 can be moved up and down; the guide rail 65 and the rack 66 are inclined The oblique arrangement can lengthen the up and down moving distance of the base 61, which is beneficial to pulling the bottom paper on the sheet; the upper clamping plate 62 and the lower clamping plate 63 are arranged correspondingly up and down, and one of them is fixed on the base 61, such as the lower clamping plate 63 is in a fixed state, and the other of the two is movable on the base 61 through the fourth motor 68 and the gear mechanism 69, that is, the upper clamping plate 62 is in a movable state. In this way, the gear mechanism 69 is driven to rotate by the fourth motor 68, and the upper clamping plate 62 is made to move vertically up and down relative to the lower clamping plate 63, so that the bottom paper on the sheet can be clamped or released, so that the pulling component 6 can complete the pulling of the bottom paper.

[0044] In another example, a blowing pipe 64 is further provided on the base 61. Through the blowing effect of the blowing pipe 64, the bottom paper can be blown out of the frame 1 after being loosened by the upper and lower clamps, thereby automatically completing the bottom paper cleaning of the label peeling machine.

[0045] like Fig.11As shown, in another embodiment, a material shifting assembly 7 for shifting the peeled backing paper is provided on the frame 1 and below the feeding assembly 5. The material shifting assembly 7 is composed of a fifth motor 71, a base plate 72, a conveyor belt 73, a track 74, a slider 75, a conveyor wheel 76, and a paper shifting rod 78. The base plate 72 is installed on one side of the length direction of the frame 1, and is provided with a fifth motor 71, a conveyor wheel 76 connected to the fifth motor 71 through a conveyor belt 73, and a track 74 extending along the length direction of the frame 1. The slider 75 is slidably matched with the track 74 and is fixedly connected to the conveyor belt 73, and a paper shifting rod 78 is provided on the slider 75. In this way, driven by the fifth motor 71 and with the assistance of the conveyor wheel 76, the conveyor belt 73 rotates and drives the slider 75 to make reciprocating linear sliding on the track 74 and along the length direction of the frame 1. That is, when the base paper on the sheet is long and the height of the pulling assembly 6 is not enough to pull the base paper away (the label is not completely peeled off), the paper-pulling rod 78 on the material-pulling assembly 7 can be placed in a suitable position near the pulling assembly 6 through the movement mode of the material-pulling assembly 7, and the base paper is pulled down to a low position by the pulling assembly 6, so that the material-pulling rod 78 is located behind the base paper, and the base paper is further pulled by moving the material-pulling rod 78 to make a linear motion, so as to complete the label peeling work of the long sheet. With the above scheme, when the pulling assembly moves to the lowest position, the material-pulling function can be realized by moving the material-pulling assembly, and finally all the labels of a sheet of material are completed, and finally the base paper is discharged and the previous action is repeated.

[0046] In this example, the base 72 is provided with a first sensor 77 for detecting the initial position of the slider 75 and a second sensor 79 for detecting the lowest position of the pulling assembly 6. To ensure the orderly and effective operation of the pulling assembly 6 and the material-selecting assembly 7.

[0047] The label stripping method of the sheet material label stripping machine is described in detail below, comprising the following steps: first, the base 21 of the label output component 2 is moved on the frame 1 through the slide 24 and is spaced a certain distance from the label stripping component 3; then, the base 61 of the pulling component 6 is driven to rise with the assistance of the guide rail 65 and the rack 66 and is located between the label output component 2 and the label stripping component 3, and at the same time, the pulling component 6 pushes open the cover plate 33 on the label stripping component 3; then, the feeding component 5 is turned on to output a single sheet material to the label stripping component 3 and under the action of the check component 4, and the end of the bottom paper on the sheet material is clamped by the interaction of the upper clamping plate 62 and the lower clamping plate 63 of the pulling component 6, and is made to descend and pull the bottom paper; then, while the pulling component 6 descends, the label output component 2 is moved back to the label stripping component 3, and at the same time, the pulling component 6 is pulled ... After the label stripping component 3 strips the label from the sheet, the label discharging component 2 is used to carry the stripped label; if the pulling component 6 is lowered to complete the stripping of the label on the sheet, that is, the displacement of the pulling component 6 can ensure that all the labels on the sheet are stripped, the upper clamping plate 62 and the lower clamping plate 63 are directly loosened to release the clamping of the bottom paper and then discharge the bottom paper to complete a single sheet stripping, and the above steps are repeated to perform the next sheet stripping action; if the label stripping component 3 fails to complete the sheet stripping when the pulling component 6 is lowered to the low position, that is, the displacement of the pulling component 6 is not enough to ensure that all the labels on the sheet are stripped, the stripping bottom paper needs to be moved horizontally by the material shifting component 7 to continue the stripping, so as to further stretch the bottom paper to complete the stripping of all the labels on a sheet, and then the pulling component 6 releases the clamping of the bottom paper and discharges the bottom paper, and the previous actions are repeated.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.

The frame has a bottom paper outlet (9) at the end side where the feeding component is located. The shells on both sides of the frame in the length direction are provided with observation ports (81) for observing the movement of the pulling component.

7. A method for stripping labels from a sheet material, characterized in that: Using the sheet material label stripping machine as described in any one of claims 1 to 6, the sheet material label stripping method comprises the following steps: Step 1), moving the label discharging component and separating it from the label stripping component by a predetermined distance; Step 2), driving the pulling component to rise and be located between the label discharging component and the label stripping component; Step 3), start the feeding component to output a single sheet of material to the label stripping component; Step 4), the pulling component clamps the end of the bottom paper on the sheet and descends to pull the bottom paper; Step 5), while the pulling component is lowered, the label discharging component is moved back to the label stripping component, and after the label stripping component strips the label from the sheet, the label discharging component is used to carry the stripped label; Step 6), after the pulling component descends to complete the peeling of the labels on the sheet, the bottom paper is released and discharged to complete a single sheet stripping. If the stripping component fails to complete the sheet stripping when the pulling component descends to the low position, the stripping component moves the stripped bottom paper horizontally to continue stripping, so as to complete the stripping of all labels on a sheet, and then the pulling component releases the clamping of the bottom paper and discharges the bottom paper, and the previous action is cycled; repeat the above steps to perform the next sheet stripping action.
