Referring to fig. 2 to 4, the active film pulling mechanism 410 includes a bottom film pressing rod 411, a bottom film guide 413, and a driving unit 412. A base film pressure bar 411 is installed on the upper portion of the base 110 of the cabinet 100, and a base film 510 from which the label 520 is removed is supported on the outer circumferential surface of the base film pressure bar 411. A basement membrane guide plate 413 is disposed below the basement membrane pressing rod 411, and the basement membrane guide plate 413 is fixed to the bottom of the base 110. The driving assembly 412 is used to power the rotation of the bottom film pressing bar 411. The base 110 has a feed opening 111 formed beside the bottom film guide 413, and when the driving unit 412 is turned on, the bottom film 510 with the label 520 removed is driven by the bottom film pressing rod 411 to be continuously discharged from the inner cavity of the base 110 through the feed opening 111 along the bottom film guide 413.

Referring to fig. 3 and 4, the movable film pressing mechanism 420 includes a first rotating shaft 424, a mounting seat 422, a pressing roller 421 and a pressing assembly 423. The first rotating shaft 424 is installed at the bottom of the base 110, the installation base 422 is connected with the first rotating shaft 424, the installation base 422 can rotate along with the first rotating shaft 424, the nip roller 421 is rotatably installed at the upper part of the installation base 422, and the nip roller 421 is just opposite to the bottom film pressing rod 411. The pressing component 423 can apply a certain pressing force to the mounting base 422, so as to drive the mounting base 422 to rotate around the first rotating shaft 424, and finally achieve the purpose of pressing the material pressing roller 421 against the bottom film pressing rod 411.

When the stripper is idle, the pressing force of the pressing component 423 on the mounting seat 422 can be cancelled, so that the pressing roller 421 and the bottom film pressing rod 411 are separated from each other by releasing the abutting state, and a gap with a certain width exists between the pressing roller 421 and the bottom film pressing rod 411. At this time, a human hand can go deep into the inner cavity of the base 110 from the opening provided on the side of the base 110, and pull the base film 510 out of the gap between the nip roller 421 and the base film presser bar 411. When the stripper needs to be put into use, the pressing component 423 can press the mounting seat 422, and the mounting seat 422 rotates to clamp the bottom film 510 between the pressing roller 421 and the bottom film pressing rod 411.

Referring to fig. 4 and 8, in particular, the pressing assembly 423 includes a second rotating shaft 4231, a cam 4232 and a handle 4233. The second rotating shaft 4231 is installed on the upper portion of the base 110 and is parallel to the first rotating shaft 424, the cam 4232 is fixedly installed in the middle of the second rotating shaft 4231, the handle 4233 is connected with the end portion of the second rotating shaft 4231, when the handle 4233 rotates clockwise, the handle 4233 drives the cam 4232 to rotate through the second rotating shaft 4231, the cam 4232 is pressed against the mounting seat 422, and therefore the pressing roller 421 is pressed against the base membrane pressing rod 411; when the handle 4233 rotates counterclockwise, the handle 4233 drives the cam 4232 to rotate through the second rotating shaft 4231, the cam 4232 is separated from the mounting seat 422, and the pressing roller 421 is further driven to be separated from the base film pressing rod 411.

Referring to fig. 4, in particular, the mounting block 422 includes a mounting plate 4221, a spring pressure plate 4222 and a compression spring 4223. The mounting plate 4221 is fixedly mounted on the first rotating shaft 424, the spring pressing plate 4222 can rotate relative to the first rotating shaft 424, the main body part of the spring pressing plate 4222 is opposite to and parallel to the mounting plate 4221, the pressing roller 421 is mounted on one side of the mounting plate 4221 facing the basement membrane pressing rod 411, one end of the compression spring 4223 is connected with one side of the mounting plate 4221 departing from the basement membrane pressing rod 411, and the other end of the compression spring 4223 is connected with the main body part of the spring pressing plate 4222. When the handle 4233 drives the cam 4232 to abut against the spring pressure plate 4222, the spring pressure plate 4222 transmits the abutting force to the mounting plate 4221 through the compression spring 4223, and the mounting plate 4221 rotates counterclockwise along with the first rotating shaft 424, so that the pressing roller 421 abuts against the base film pressing rod 411. Due to the arrangement of the spring pressure plate 4222 and the compression spring 4223, under the buffering action of the compression spring 4223, the pressing roller 421 is not violently impacted when being abutted against the base film pressing rod 411, and the pressing roller 421 and the base film pressing rod 411 are prevented from being damaged. Meanwhile, when the cam 4232 abuts against the spring pressing plate 4222, the cam 4232 is more stable and reliable in abutting against the spring pressing plate 4222 due to the elastic force of the compression spring 4223, and even if the cam 4232 and the spring pressing plate 4222 collide with each other, the cam 4232 and the spring pressing plate 4222 cannot be loosened suddenly, and the abutting state of the material pressing roller 421 and the bottom film pressing rod 411 is always maintained in the working process.

Referring to fig. 4, further, an extension spring 426 is disposed below the second rotation shaft 4231, one end of the extension spring 426 is connected to the spring pressing plate 4222, and the other end of the extension spring 426 is connected to the housing 100. Because the extension spring 426 is provided, when the nip roller 421 abuts against the bottom film presser bar 411, the extension spring 426 is in a stretched state, and the pulling force generated by the extension spring is smaller than the abutting force of the cam 4232 on the spring pressing plate 4222, so that the nip roller 421 and the bottom film presser bar 411 are not separated. When the cam 4232 releases the abutting force on the spring pressing plate 4222, under the traction of the tensile force of the extension spring 426, the spring pressing plate 4222 drives the mounting plate 4221 to rotate clockwise along with the first rotating shaft 424, so that the separation between the pressing roller 421 and the basement membrane pressing rod 411 can be automatically realized. When the extension spring 426 is not provided, the mounting plate 4221 may be manually rotated.

The spring retaining plate 4222 is provided with a slotted hole (not shown) which is a kidney-shaped hole and keeps a certain length, and the slotted hole extends along the length direction of the main body part of the spring retaining plate 4222. A limit screw 425 penetrates through the slotted hole, one end of the limit screw 425 is fixed on the mounting plate 4221, the maximum offset of the spring pressing plate 4222 relative to the mounting plate 4221 is limited under the combined action of the slotted hole and the limit screw 425, and when the pressing roller 421 abuts against the bottom membrane pressing rod 411, the protruding part of the cam 4232 can be ensured to be in effective contact with the spring pressing plate 4222 and cannot be separated.

Referring to fig. 1 and 2, the label supporting mechanism 300 includes a label supporting plate 310 and a sensor 320. The label support plate 310 is fixed on the upper portion of the base 110, a plurality of saw teeth 311 are arranged on one surface of the label support plate 310 contacting with the labels 520 at intervals, and the saw teeth 311 can make the label support plate 310 effectively apply bearing force to the labels 520 separated from the bottom film 510, so that the labels 520 are prevented from being tightly attached to the label support plate 310, and the labels 520 can be taken away conveniently. The middle of the label supporting plate 310 is provided with a mounting hole, and the inductor 320 is mounted in the mounting hole. In the label peeling process, if one label 520 is peeled off from the base film 510, and the front end of the label 520 contacts with the sensor 320, the sensor 320 senses that the label 520 peeled off from the label support plate 310 exists, and then transmits feedback information to the motor 4121, the motor 4121 stops rotating, so that the base film pressure bar 411 stops rotating, and the label peeling machine stops peeling the label 520; when the label 520 is removed from the label supporting plate 310, the sensor 320 also transmits a feedback signal to the motor 4121, the motor 4121 drives the bottom film pressing rod 411 to rotate, the label peeling machine continues to start the peeling operation of the label 520, and the operation is repeated in a cycle.

The roll material 500 is wound around the third rotating shaft 140, and one end of the roll material 500 reaches the bottom film pressing bar 411 through the first guiding shaft 220, the roll material guiding plate 250, the second guiding shaft 230, the label peeling plate 210, and the third guiding shaft 240, and then reaches the lower opening 111 at the bottom of the base 110 along the bottom film guiding plate 413. The roll material guide plate 250 and the label peeling plate 210 support the roll material 500 upwards, the first guide shaft 220 and the second guide shaft 230 are respectively arranged at two sides of the roll material guide plate 250, and the first guide shaft 220 and the second guide shaft 230 both form downward pressure on the roll material 500, so that the roll material 500 is tightened. The third guide shaft 240 is positioned below the label peeling plate 210, and the third guide shaft 240 applies downward pressure to the base film 510 to tension it. The clamping rings 221 are further disposed at both ends of the first guide shaft 220, the coil stock 500 can only move within a width range defined by the two clamping rings 221, and the clamping rings 221 play a role in preventing the coil stock 500 from deviating.

When the roll material 500 contacts the label peeling plate 210, the arc surface 213 is beneficial to the smooth movement of the roll material 500 on the label peeling plate 210, and the phenomenon of clamping stagnation is avoided.

Referring to fig. 5 and 6, when the label peeling machine starts to work, firstly, the handle 4233 is rotated to make the nip roller 421 abut against the base film pressing bar 411 to clamp the base film 510 therebetween, then, the motor 4121 is started, the motor 4121 drives the base film pressing bar 411 to rotate, the nip roller 421 and the base film pressing bar 411 form flexible extrusion on the base film 510 together under the action of the compression spring 4223, and the nip roller 421 rotates in cooperation with the base film pressing bar 411 to draw the base film 510 to move. In the moving process of the base film 510, the roll material 500 passes through the gap between the label peeling plate 210 and the label supporting plate 310, the base film 510 moves along the vertical direction (the direction perpendicular to the supporting surface 211), and due to the action of the sharp angle formed by the wedge-shaped structure, the labels 520 gradually separate from the base film 510 in the moving process of the base film 510 and move to the label supporting plate 310 along the horizontal direction (the direction parallel to the supporting surface 211), so that the labels 520 are successfully peeled off from the base film 510.
