The second guide plate 105d is connected to the circumferential surface of the first roller 108, and the multiple protrusions 105c are evenly distributed at the connection between the first roller 108 and the second guide plate 105d. The release paper 402 conveyed by the first roller 108 and the second roller 112 can be fed out along the second guide plate 105d to the outside of the machine assembly 1. The multiple protrusions 105c can prevent the release paper 402 from wrapping around the first roller 108 and causing blockage inside the machine assembly 1.

[0031] The handheld bracket 106 is disposed on the side of the first guide plate 101q away from the labeling working surface. The handheld bracket 106 has a fourth latching portion 106c on the side near the first side wall 101p, and a fifth latching portion 101o corresponding to the fourth latching portion 106c on the first side wall 101p. The handheld bracket 106 is connected to the fifth latching portion 101o of the first side wall 101p via the fourth latching portion 106c. The clamping member is spaced a preset distance from the end of the first guide plate 101q in its extending direction, and the clamping member simultaneously connects the first side wall 101p and the handheld bracket 106. The sticker 401, separated from the end of the first guide plate 101q in its extending direction, is clamped by the clamping member while adhering to the labeling working surface. The handheld bracket 106 includes a hand grip 106b, which is located on the side of the handheld bracket 106 away from the labeling working surface.

[0032] When the clamping member presses the sticker 401, the circumferential surface of the first roller 108 is in contact with the sticker application surface. By holding the handle 106b and pulling the body assembly 1 along the application direction of the sticker 401, the first roller 108 rolls on the sticker application surface, and the clamping member can press the previous sticker 401 to make the sticker 401 flatly adhered to the sticker application surface. At the same time, the first roller 108 drives the second roller 112 to rotate through surface friction during the rolling process, so that the release paper 402 can be sent out from the second guide plate 105d to the outside of the body assembly 1.

[0033] In some other embodiments, the paper output limiter 104 is rotatably connected to the fourth mounting hole 101k of the first sidewall 101p via the eighth mounting hole 104e and the second mounting screw 126, and the ninth mounting hole 104f is rotatably connected to the fourteenth mounting hole 128c of the second sidewall 128e via the first mounting screw 125, so that the paper output limiter 104 can reciprocate relative to the first guide plate 101q inside the machine assembly 1.

The end of the pin 120a facing away from the protrusion 120b is connected to a toggle handle 121. When the operator presses the toggle handle 121, the toggle handle 121 drives the swing linkage 120 to rotate relative to the second end cover 127, so that the protrusion 120b rotates within the swing groove 104g. When the protrusion 120b abuts against the abutment block 104h, the two tension springs 124 are in a stretched state. At this time, the circumferential surface of the second roller 112 separates from the circumferential surface of the first roller 108. The operator can insert the release paper 402 between the first roller 108 and the second roller 112, or remove the release paper 402 between the first roller 108 and the second roller 112. When the protrusion 120b separates from the abutment block 104h, the two tension springs 124 are in a reset state. At this time, the circumferential surface of the second roller 112 abuts against the circumferential surface of the first roller 108, thereby increasing the frictional force between the first roller 108 and the second roller 112 and the release paper 402.

[0034] In some other embodiments, the pressing element is a scraper 118 or a brush. When the scraper 118 or brush presses the sticker 401, the circumferential surface of the first roller 108 is in contact with the sticker application surface. By holding the handle 106b and pulling the machine assembly 1 along the application direction of the sticker 401, the first roller 108 rolls on the sticker application surface, and the pressing element can press the previous sticker 401 to make the sticker 401 flatly adhered to the sticker application surface. At the same time, the first roller 108 drives the second roller 112 to rotate through surface friction during the rolling process, thereby feeding the release paper 402 from the second guide plate 105d to the outside of the machine assembly 1.

[0035] In some other embodiments, the clamping element is a third roller 116. A fifth shaft hole 106a is provided on the handheld bracket 106 of the machine body, and a sixth shaft hole 101e is provided on the first side wall 101p corresponding to the fifth shaft hole 106a. A third rotating shaft 115 is rotatably connected between the fifth shaft hole 106a and the sixth shaft hole 101e, and a third roller 116 with a rubber-coated surface is fitted on the third rotating shaft 115. When the circumferential surface of the third roller 116 presses against the sticker 401, the circumferential surface of the first roller 108 is in contact with the sticker application surface. By holding the handle 106b and pulling the machine assembly 1 along the sticker application direction, the first roller 108 rolls on the sticker application surface while the third roller 116 rolls against the previous sticker 401 to make the sticker 401 flatly adhered to the sticker application surface. At the same time, the first roller 108 drives the second roller 112 to rotate through surface friction during the rolling process, thereby feeding the release paper 402 from the second guide plate 105d to the outside of the machine assembly 1.

[0036] In some other embodiments, the clamping element is a third roller 116. A mounting cavity 101c is located on the side of the first sidewall 101p opposite to the first guide plate 101q. A second end cap 127 is connected to the side of the first sidewall 101p opposite to the first guide plate 101q to close the mounting cavity 101c. A seventh shaft hole 101g is provided on the side of the first sidewall 101p corresponding to the mounting cavity 101c. A first rotating shaft 107 extends into the mounting cavity 101c through the first shaft hole 101f. A first gear 110 is rotatably connected to the seventh shaft hole 101g via a first bearing assembly 109. A second gear 114 is coaxially connected to the end of the first rotating shaft 107 within the mounting cavity 101c, and the first gear 110 meshes with the second gear 114. The third rotating shaft 115 extends into the mounting cavity 101c through the sixth shaft hole 101e, and the end of the third rotating shaft 115 in the mounting cavity 101c is coaxially connected to the third gear 117, which meshes with the first gear 110. By presetting the diameter of the third roller 116 and the diameter of the first roller 108, and / or presetting the transmission ratio between the third gear 117 and the second gear 114, it is ensured that the third roller 116 has a linear speed equal to or slightly greater than that of the first roller 108, thereby preventing the first roller 108 from breaking the release paper 402 while the third roller 116 is rolling the sticker 401.

[0037] Specifically, taking a specific design embodiment as an example, the length of the sticker 401 on the common label 4 is 130mm, the spacing between two adjacent stickers 401 on the label 4 is 2mm, and the preset spacing between the cutting point of the third roller 116 and the end of the first guide plate in the extension direction is set to 20mm. The preset spacing of 20mm can ensure that the sticker 401 can be pre-peeled by 20mm when it comes into contact with the third roller 116. Therefore, as long as the straight distance of the first roller 108 exceeds 110mm, the release paper 402 at the bottom of the sticker 401 can be completely conveyed and peeled off by the first roller 108. According to the above design requirements, the diameter of the third roller 116 is preset to be 30mm, the diameter of the first roller 108 is 28mm, and the module and number of teeth of the second gear 114 and the third gear 117 are the same. Calculations show that the straight-line distance of the third roller 116 is equal to (the straight-line distance of the first roller 108 * the diameter of the third roller 116) / the diameter of the first roller 108, which is approximately (110mm * 30mm) / 28mm ≈ 117.86mm. When the first roller 108 rolls a straight distance of 110mm, the third roller 116 rolls a straight distance of approximately 118mm. The straight distance of the third roller 116 rolling 118mm plus the preset spacing of 20mm is greater than the length of the sticker 401, which is 130mm. Therefore, after the first roller 108 completely peels off the 130mm release paper 402, the third roller 116 does not press the second sticker 401 tightly, thus avoiding the release paper 402 being pulled apart due to excessively fast peeling. If the diameter of the third roller 116 is further increased, according to the above design requirements, the length of the sticker 401 * the diameter of the first roller 108 / the straight-line distance of the first roller 108 is approximately 130mm * 28mm / 110mm ≈ 33.09mm. That is, when the diameter of the third roller 116 exceeds 33mm, the linear speed of the first roller 108 will be too low. As a result, when the third roller 116 rolls the second sticker 401, the first roller 108 cannot completely peel off and convey the release paper 402 at the bottom of the previous sticker 401, causing the sticker 401 and the release paper 402 to remain stuck together, and there is a risk that the release paper 402 will not be completely peeled off. Therefore, according to the above design requirements, if the diameter of the first roller 108 is designed to be 28mm, the diameter of the third roller 116 should be no less than 28mm and less than 33mm. Considering the possibility of surface wear on the third roller 116, the diameter of the third roller 116 is designed to be 30mm, which is slightly larger than 28mm, so as to ensure that the third roller 116 has a linear speed that is slightly greater than that of the first roller 108 during the operation of the labeler.When the label applicator is in operation, the circumferential surface of the first roller 108 does not contact the label applicator working surface. During the operation of the label applicator, while the third roller 116 rolls the label 401, it drives the first roller 108 to rotate through the meshing of the three gears. During the rotation of the first roller 108, the friction force drives the second roller 112, which is in contact with its surface, to rotate. Thus, while rolling the label 401, the release paper 402 can be conveyed to the outside of the machine assembly 1.

[0038] In some other embodiments, the paper feed limit frame 102 is provided with an adjusting screw hole 102d corresponding to the ninth shaft hole 102a. The adjusting screw hole 102d communicates with the ninth shaft hole 102a, and an adjusting screw 119 is connected in the adjusting screw hole 102d. The end of the adjusting screw 119 abuts against the circumferential surface of the support rod 103 in the ninth shaft hole 102a. The paper feed limit frame 102 and the support rod 103 can be locked or unlocked by turning the adjusting screw 119. When the adjusting screw 119 is in the unlocked state, the paper feed limit frame 102 can move closer to or further away from the first side wall 101p along the support rod 103, thereby changing the interval distance between the second side wall 128e and the first side wall 101p to meet the limiting requirements of sheet sizes of different widths.

[0039] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: The above embodiment provides a label applicator with a detachable supply box 2. This label applicator adopts a split, detachable connection design. The main body assembly 1 is used to complete the label applicator operation, and the supply box 2 is used to supply the label 4. During use, the supply box 2 can be snapped onto the main body assembly 1 and held together with it, or it can be detached separately and placed on a table or snapped onto work clothes or a belt. Alternatively, the main body assembly 1 can be used alone for label applicator operations. This effectively reduces the weight of the label applicator and significantly reduces the workload of the operators.
