Description

TECHNICAL FIELD

[0001] The utility model relates to stationery product field, especially a compact structure sticker machine. BACKGROUND

[0002] Sticker rolls are stationery products that are wound from a strip material. The sticker roll includes backing paper and stickers, which are releasably attached to the backing paper. The stickers include an adhesive side and a printed side, and the printed side is pre-printed with symbols or patterns. The stickers usually include various animals or other themes that are interesting to children, so many children like to collect stickers and attach them to books, textbooks, lunch boxes and other items. However, in such an arrangement, the stickers are easily soiled or accidentally attached to other items.

[0003] To facilitate the distribution of stickers, the prior art such as Chinese utility model patent (publication number: CN2280699Y) and US patent (publication number: US5770008A) discloses a press-type sticker dispenser. The dispenser requires manual installation of the sticker roll to the support shaft and installation of the first section of the sticker roll to the corresponding channel, and then drives the friction wheel by pressing the rack gear, and the friction wheel moves the strip material by friction.

[0004] Another prior art such as Chinese utility model patent (publication number: CN216003626U) discloses a sticker box.

The sticker machine 100 is configured to peel off the sticker P2 from the backing paper P1 during the conveying of the sticker P2.

[0056] In an embodiment of the sticker machine 100 of the present application, as Figures 1 to 6As shown, it comprises a main body 10 and a sticker box 20 detachably mounted on the main body 10, the sticker box 20 is adapted to receive the sticker roll, the sticker box 20 is locked or unlocked with the main body 10 by a locking device 30. The components in an embodiment of the sticker machine 100 are described below.

[0057] As shown in Figure 2 and Figure 6 The main body 10 includes a mounting cavity 101, a motor 15, a transmission assembly 16, a circuit assembly (not shown), a mounting column 11, etc. The mounting cavity 101 is surrounded by a bottom wall and a peripheral wall, the space shape of the mounting cavity 101 matches the shape of the sticker box 20, and is used to receive the sticker box 20.

[0058] As shown in Figure 5 and Figure 6 The mounting column 11 is a hollow column, which is configured to at least partially accommodate the motor 15 therein, the mounting column 11 protrudes into the mounting cavity 101, and the upper end of the mounting column 11 extends to near the top of the sticker box 20. The main part of the motor 15 is accommodated in the mounting column 11, and the output shaft of the motor 15 faces downward and is connected to the male coupler 13 on the main body 10 through the transmission assembly 16 such as a gear set. The male coupler 13 protrudes in the mounting cavity 101, and is used to be coupled with the female coupler 213 on the sticker box 20 when the sticker box 20 is mounted in the mounting cavity 101, so as to realize power transmission.

[0059] The main body 10 further comprises an ejector 12, which is configured to provide an elastic force to urge the sticker box 20 to pop out a distance from the mounting cavity 101. The ejector 12 is elastically deformed when the sticker box 20 is mounted in the mounting cavity 101, and the ejector 12 stores the elastic force; when the sticker box 20 is unlocked, the elastic force provided by the ejector 12 can pop the sticker box 20 out a distance, so as to facilitate the user to pinch the two ends of the sticker box 20 to take out the sticker box 20. In an embodiment, the ejector 12 includes a columnar coil spring and a support cap pushed by the columnar coil spring.

[0060] As shown in Figure 2 and Figure 3As shown, the sticker cartridge 20 comprises a cartridge body, a sticker roll sleeve 211 protruding from the cartridge body, and a winding shaft 212 for winding the backing paper P1 under the drive of the motor 15 to wind the sticker roll. The cartridge body comprises a cartridge body 21 and a cartridge cover 22 covering the cartridge body 21, and the cartridge body 21 and the cartridge cover 22 enclose a sticker compartment 210. The cartridge cover 22 is fixed to the cartridge body 21 by screwing the screw from bottom to top through the cartridge body 21 and locking it on the cartridge cover 22. Specifically, the cartridge body 21 is provided with a screw hole 215, and the bottom surface of the cartridge cover 22 is provided with a screw post 221, and the screw is locked on the screw post 221 from bottom to top; in this way, the top part of the cartridge cover 22 and other parts that are often exposed are not exposed to the screw connection structure, so that the cartridge cover 22 looks neat and beautiful. The bottom surface of the cartridge body 21 is provided with a female coupler 213, which can be coupled and connected with the male coupler 13 on the main body 10 to achieve power transmission. The female coupler 213 is connected to the winding shaft 212 at one end in the cartridge body, and is used to drive the winding shaft 212 to rotate to wind the backing paper P1 on the winding shaft 212.

[0061] The sticker roll sleeve 211 is used for the sticker roll to be movably sleeved thereon, and the sticker roll sleeve 211 is a hollow cylindrical sleeve protruding from the sticker compartment 210 of the cartridge body. When the sticker cartridge 20 is installed in the main body 10, the sticker roll sleeve 211 is sleeved on the mounting column 11. The top end of the sticker roll sleeve 211 has an opening 2110 and a notch 2111 at one end of the opening 2110. The opening 2110 is used for the locking device 30 that has been installed on the mounting column 11 to pass through when the sticker cartridge 20 is installed in the main body 10, and is clamped at the notch 2111 to achieve the locking of the sticker cartridge 20 and the main body 10. The wall part corresponding to the clamping part of the locking device 30, that is, the wall part provided with the notch 2111, is provided as a flat part 2112, which is configured to increase the distance between the clamping part and the sticker roll. The flat part 2112 is arranged at the wall part of the sticker roll sleeve 211 facing the winding shaft 212, so that when the winding shaft 212 is pulled to rotate the sticker roll, the flat part 2112 is on the side of the sticker roll sleeve 211 away from the sticker roll, thereby providing space for easily taking the sticker roll off the sticker roll sleeve 211. In this embodiment, the flat part 2112 of the sticker roll sleeve 211 tends to be a vertical extending plane, and the wall surface of other parts of the sticker roll sleeve 211 tends to be a cylindrical surface. The sticker cartridge 20 is also provided with a peeling part 214, which is used to peel the sticker P2 on the backing paper P1 when the backing paper P1 is turned to wind on the winding shaft 212.
