[0025] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the present invention. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0026] Example 1

[0027] like Figure 1-6 As shown, this utility model provides a dual-channel offline bag dispensing machine, including a bag dispensing machine body 10, an inner cavity 101 is opened inside the bag dispensing machine body 10, and a bag winding roller 20 is provided at the top inside the inner cavity 101.

[0028] Fixing component 30 is provided at both ends of the bag winding roller 20 and is used for installing and fixing the bag winding roller 20;

[0029] Limiting component 40 is located on the side wall of the inner cavity 101 and is used to limit the movement of the bag roller 20.

[0030] This utility model's dual-channel offline bag dispensing machine allows personnel to install and disassemble the bag winding roller 20 using the fixing component 30 according to actual needs, thus facilitating the replacement of the bag roll shaft. In addition, when the user pulls the plastic bag, the limiting component 40 can flexibly control whether the bag winding roller 20 rotates, preventing the user from rotating the bag winding roller 20 when tearing the bag, thus ensuring the stability of the bag dispensing machine.

[0031] Furthermore, in another embodiment, the fixing component 30 includes a mounting plate 301, a locking hole 302, a chuck 303, a locking post 304, and a first limiting spring 305. The mounting plate 301 is mounted on the side wall of the inner cavity 101 via a bearing. The locking hole 302 is opened inside the mounting plate 301. The chuck 303 is attached to the surface of the mounting plate 301, and the locking post 304 is locked inside the locking hole 302. The chuck 303 is connected to the bag winding roller 20 via the first limiting spring 305.

[0032] When the bag winding roller 20 needs to be installed, the relevant personnel can align the chucks 303 at both ends of the bag winding roller 20 with the mounting plate 301, and then press the chucks 303 to insert the locking pins 304 into the locking holes 302 of the mounting plate 301. At this time, the first limiting spring 305 is in a compressed state. The elastic force of the first limiting spring 305 can be used to firmly lock the locking pins 304 in the locking holes 302, thereby achieving quick fixation of the bag winding roller 20. When the bag winding roller 20 needs to be disassembled, simply pull the chucks 303 in the opposite direction to overcome the elastic force of the first limiting spring 305, and the locking pins 304 can be disengaged from the locking holes 302. The operation is convenient and efficient, making it easier for relevant personnel to replace the bag winding shaft.

[0033] Furthermore, in another embodiment, the limiting assembly 40 includes a limiting plate 401, a connecting rod 402, an overlapping plate 403, a positioning post 404, a second limiting spring 405, and a baffle 406. The limiting plate 401 is disposed above the mounting plate 301, and a positioning groove 50 is formed on the outer wall of the mounting plate 301. The limiting plate 401 is used to engage the mounting plate 301. The connecting rod 402 is connected to the outer wall of the limiting plate 401. The overlapping plate 403 is connected to the lower outer wall of the connecting rod 402. The positioning post 404 is disposed on the surface of the overlapping plate 403. The second limiting spring 405 is sleeved around the positioning post 404. The baffle 406 is disposed above the overlapping plate 403 and is fixed to the inner wall of the inner cavity 101. The positioning post 404 also passes through the baffle 406.

[0034] Under the action of the second limiting spring 405, the limiting plate 401 always has downward pressure. When the bag winding roller 20 is stationary, the limiting plate 401 is engaged in the positioning groove 50 on the outer wall of the mounting plate 301, thereby restricting the rotation of the mounting plate 301 and preventing the bag winding roller 20 from rotating when the user tears the bag. When the user needs to pull the plastic bag, the overlapping plate 403 can be pushed up. During this process, the second limiting spring 405 will be squeezed and compressed by the baffle 406. At the same time, the overlapping plate 403 will drive the limiting plate 401 to move upward through the connecting rod 402, and then disengage from the positioning groove 50. Then the user can pull the plastic bag out of the bag winding roller 20. After the plastic bag is pulled to a suitable length... After the user loosens the overlapping plate 403, the second limiting spring 405 will reset and push the overlapping plate 403 back, which will then drive the limiting plate 401 to move down and lock into the positioning groove 50. After the limiting plate 401 is re-locked into the positioning groove 50, the mounting plate 301 can be fixed, preventing the user from rotating around the bag roller 20 when tearing the plastic bag, thus ensuring the stability of the user when tearing the plastic bag around the bag roller 20. It is worth noting that if the limiting plate 401 does not lock into the positioning groove 50 when the overlapping plate 403 is loosened, the limiting plate 401 can be locked into the positioning groove 50 by slightly rotating the mounting plate 301, without affecting the fixation of the mounting plate 301.

[0035] Furthermore, in another embodiment, the bag roller 20 has through grooves 306 at both ends.

[0036] The through groove 306 facilitates the regular maintenance and replacement of the first limit spring 305 by relevant personnel, preventing the fixing effect of the fixing component 30 from being poor due to the aging of the first limit spring 305.

[0037] Furthermore, in another embodiment, the inner wall of the inner cavity 101 is provided with a guide block 60, and the connecting rod 402 passes through the guide block 60.

[0038] The guide block 60 guides the movement of the connecting rod 402, ensuring that the limit plate 401 does not deviate during the up and down movement, thus ensuring the stability of the limit assembly 40.

[0039] Furthermore, in another embodiment, both the inner cavity 101 and the bag-winding roller 20 are provided in two.

[0040] The design of two inner cavities 101 and two bag-winding rollers 20 enables the bag dispenser to dispense two different sizes or materials of plastic bags at the same time, effectively improving work efficiency and meeting diverse usage needs.

[0041] Furthermore, in another embodiment, each mounting plate 301 is provided with three locking holes 302, and each chuck 303 is provided with three locking posts 304, which are used in conjunction with the three locking holes 302.

[0042] The cooperation of the three locking holes 302 on the mounting plate 301 and the three locking posts 304 on the chuck 303 further enhances the stability of the bag winding roller 20 installation, making the bag winding roller 20 more evenly stressed during rotation and preventing wobbling or deviation.

[0043] Furthermore, in another embodiment, a threaded stop 407 is detachably provided above the positioning post 404.

[0044] The threaded stop 407 prevents the positioning pin 404 from dislodging from the baffle 406, and also facilitates the replacement or maintenance of the second limit spring 405 by relevant personnel. The positioning pin 404 can be removed from the baffle 406 simply by unscrewing the threaded stop 407.

[0045] Working principle: Relevant personnel need to check whether the inner cavity 101 of the bag dispensing machine body 10 is clean to ensure that there are no foreign objects affecting the installation and rotation of the bag winding roller 20. Then, according to the specifications of the plastic bags to be dispensed, select a suitable bag rolling shaft and install it on the bag winding roller 20. During installation, follow the operation steps of the fixing component 30, align the locking pin 304 on the chuck 303 with the locking hole 302 of the mounting plate 301 and press it down. Use the elastic force of the first limit spring 305 to complete the fixing.

[0046] After installation, observe whether the limiting plate 401 of the limiting component 40 is properly engaged in the positioning groove 50 of the mounting plate 301 to ensure that the bag winding roller 20 remains stationary when not in use. Then, pull the opening of the plastic bag out from the bag winding roller 20 and pass it through the preset discharge port of the bag dispensing machine body 10 to prepare for bag dispensing. In the actual bag dispensing process, when the user needs to pull the plastic bag, push the overlapping plate 403 upward, and the limiting plate 401 will move upward and disengage from the positioning groove 50 through the connecting rod 402. At this time, the bag winding roller 20 can rotate freely, and the user can smoothly pull out the plastic bag of the required length. After the overlap plate 403 is released, the second limit spring 405 returns to its original position, and the limit plate 401 re-engages into the positioning groove 50, restricting the rotation of the bag winding roller 20 and preventing the plastic bags from continuing to be output due to inertia. If two types of plastic bags need to be dispensed at the same time, the corresponding bag rolling shafts can be installed on the two bag winding rollers 20 respectively, and the same steps as above can be followed to achieve simultaneous bag dispensing through two channels, effectively improving work efficiency. When the plastic bags on the bag rolling shaft are used up, pull the chuck 303 in the opposite direction to disengage the chuck post 304 from the chuck hole 302, and the bag winding roller 20 can be removed and a new bag rolling shaft can be replaced. The whole process is simple to operate and does not require complicated tools, making it suitable for scenarios where bag rolling shafts need to be replaced frequently.
