[0011] The label paper unwinding device for easy filling described above further includes: a stop block embedded in one side of the top of the outer shell, and two slots adapted to the stop block are provided on one side of the top of the outer shell.
[0012] In summary, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model adopts a structure design that allows for quick ejection of the shaft. When changing labels of different widths, simply rotate and pull out the corresponding shaft. After installing the label, rotate the corresponding shaft back onto the machine, thus quickly completing the label replacement. It can also meet the needs of rapid filling of labels of different widths, providing convenience for users' work.
[0014] 2. This utility model features two movable slots with different inner heights. The upper movable slot is designed to be open at the top of the end block. To ensure that the two support plates have the same movement distance, the lower movable slot also has an inner height that is designed according to the movement distance of the support plates. This design ensures that the support plates can move flexibly and smoothly, providing convenience for users.
[0015] 3. With the addition of end blocks and handles, the paper roll mounting rod is rotatably mounted on the end blocks.

[0018] 6. This utility model, through the setting of the clamping component, when pulling the paper roll head, first lifts the clamping component upward, then pulls out and straightens the paper roll, and then presses the clamping component back into the adapter groove. Then the spring will lock into the corresponding groove, thereby fixing the clamping component and preventing it from moving freely. Then the paper will pass over the surface of the rotating rod under the clamping plate, and the rotating rod will also rotate with it. At the same time, it can also release the rolled paper and clamp it to prevent the paper from falling, so as to ensure that the paper can move smoothly and provide convenience for users' work.
[0019] 7. This utility model uses a slot and a stop block. The stop block is installed in two blocks by plugging in. After the paper roll is installed, the stop block is snapped onto the outer shell. This can limit the paper roll and ensure that the paper roll can always rotate and unwind inside the outer shell, preventing the paper roll from shifting and providing convenience for the user's work.

[0027] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example
[0028] A label roll unwinding device for easy loading includes a housing 1. A fixed shaft 2 is fixedly installed on one side inside the housing 1. A paper roll mounting rod 3 is sleeved on the surface of the fixed shaft 2. Sliding cavities 6 are provided on the top and bottom sides of the paper roll mounting rod 3. A sliding pin 5 is slidably installed in the inner cavity of the sliding cavity 6. A spring 7 is fixedly connected to one end of the sliding pin 5. The end of the spring 7 away from the sliding pin 5 is fixedly connected to the inner wall of the sliding cavity 6. A support plate 4 located outside the paper roll mounting rod 3 is fixedly connected to one end of the sliding pin 5. A second spring 9 is sleeved on the surface of the fixed shaft 2. One end of the second spring 9 is fixedly connected to the fixed shaft 2. One end of the fixed shaft 2 abuts against the inner wall of the paper roll mounting rod 3. A label roll body 14 is sleeved on the surface of the paper roll mounting rod 3 and the support plate 4. An end block 11 located outside the housing 1 is rotatably installed on one end of the fixed shaft 2.
[0029] The specific usage process is as follows: When changing the label paper, first rotate the paper roll mounting rod 3. The paper roll mounting rod 3 is rotatably mounted on the end block 11, so it can rotate flexibly. The paper roll mounting rod 3 drives the insertion screw 10 to rotate. The insertion screw 10 is installed on the fixed shaft 2 by a threaded connection. Therefore, under the drive of the paper roll mounting rod 3, the insertion screw 10 will be disengaged from the fixed shaft 2. At this time, the compressed spring 9 will be gradually released and rebounded until the insertion screw 10 is disengaged from the fixed shaft 2. Then, the spring 9 will pop the paper roll mounting rod 3 off the fixed shaft 2. At the same time, all the components set on the paper roll mounting rod 3 will also be disengaged. Then, the paper roll mounting rod 3 drives the end block 11 to disengage from the machine. The end block 11 will drive the limit slide rod 12. Remove the label roll from the outer casing 1, and then you can install it. Installation can be done by first fitting the paper roll onto the fixed shaft 2, or by fitting the paper roll onto the paper roll mounting rod 3. The following describes one of these methods: Fit the paper roll onto the paper roll mounting rod 3, then align the paper roll mounting rod 3 with the fixed shaft 2, ensuring that the insertion screw 10 is also aligned with the hole on the fixed shaft 2. Then rotate the paper roll mounting rod 3 so that the insertion screw 10 is threaded into the fixed shaft 2, ensuring that the insertion screw 10 is fixedly installed on the fixed shaft 2. In this way, the paper roll is loaded onto the machine, that is, onto the outer casing 1. During this process, ensure that the spring 2 9 is inserted into the paper roll mounting rod 3. Then, tighten the insertion screw 10 onto the fixed shaft 2 to secure it. The paper roll mounting rod 3 continuously compresses the spring 2 9. It should be noted that the paper roll rotates on the surface of the paper roll mounting rod 3 during unwinding. Therefore, the surface of the paper roll mounting rod 3 must be designed to be smooth to reduce friction between the paper roll and the mounting rod 3 during rotation, improving the flexibility of the unwinding process. Then, the label paper end is pulled out and pressed against the lower surface of the pressing component 19 to limit the label paper downwards, preventing it from detaching from the outer casing 1. Finally, the user can use the cutter 20 to cut the label paper for easy application to the product, providing convenience for the user. It should be noted that after the paper roll is installed, the upper and lower support plates 4 will slightly support the inside of the paper roll to reduce swaying during rotation. It is important to note that the bonding strength between the support plate 4 and the paper roll must be controlled within a range that ensures the paper roll can rotate freely. The limiting slide bar 12 provides a limit when the end block 11 is disassembled and also provides a limit when the end block 11 is installed, facilitating the user's disassembly of the shaft. It should be noted that the cut paper will fall into the outer casing 1; it can be picked up and cut later. The two movable slots 8 have different inner heights because the upper movable slot 8 is open at the top of the end block 11. To ensure that the two support plates 4 have the same range of motion, the lower movable slot 8 also has a corresponding inner height based on the range of motion of the support plate 4. This ensures that the support plates 4 can move freely and smoothly, providing convenience for the user's work.The paper roll mounting rod 3 is rotatably mounted on the end block 11. The end block 11 supports the paper roll mounting rod 3, ensuring that it can rotate smoothly in its original position during disassembly and assembly, and also ensuring that the paper roll can be stably unwound. The handle 13 is for the user to grip, allowing the user to move the end block 11 and assisting in the disassembly and assembly process. The limiting slide rod 12 is fixedly mounted on the end block 11 and also slidably mounted inside the outer casing 1. Thus, when the end block 11 moves, the limiting slide rod 12... 2 also slides within the outer casing 1, thus limiting the end block 11 when it is disassembled. Simultaneously, it also limits and aligns the end block 11 and the paper roll mounting rod 3 during installation, facilitating user assembly and disassembly. The stop block 16 is installed using a plug-in method. After the paper roll is installed, the stop block 16 is snapped onto the outer casing 1, thus limiting the paper roll and ensuring it rotates and unwinds within the outer casing 1, preventing displacement and providing convenience for the user.
[0030] Therefore, the structure design allows for quick ejection of the shaft. When changing labels of different widths, simply rotate and pull out the corresponding shaft. After installing the label, rotate the corresponding shaft back onto the machine, thus quickly changing the label and accommodating the rapid filling of labels of different widths, providing convenience for users.
[0031] Two movable grooves 8 adapted to the support plate 4 are provided on the top of one side of the end block 11, and the inner heights of the two movable grooves 8 are different.
[0032] Specifically, the two movable slots 8 have different inner cavity heights because the upper movable slot 8 is opened in an open style on the top of the end block 11. In order to ensure that the two support plates 4 can have the same movement distance, the lower movable slot 8 also needs to be opened with a corresponding inner cavity height according to the movement distance of the support plate 4. This ensures that the support plate 4 can move flexibly and smoothly, providing convenience for the user's work.
[0033] A handle 13 is fixedly connected to the top of one side of the end block 11.
[0034] Specifically, regarding the configuration of end block 11 and handle 13, the paper roll mounting rod 3 is rotatably mounted on end block 11. End block 11 can support paper roll mounting rod 3, ensuring that paper roll mounting rod 3 can rotate smoothly in its original position during disassembly and assembly, and also ensuring that the paper roll can be stably unwound. Handle 13 is for users to grip, and users can move end block 11 by gripping handle 13, providing assistance for users' disassembly and assembly work.
[0035] A limiting slide rod 12 is fixedly connected to one side of the bottom of the end block 11, and one end of the limiting slide rod 12 is slidably installed inside the outer shell 1.
[0036] Specifically, the limiting slide bar 12 is fixedly installed on the end block 11 and also slidably installed inside the outer casing 1. Thus, when the end block 11 moves, the limiting slide bar 12 also slides inside the outer casing 1, thereby limiting the end block 11 when it is disassembled. At the same time, when the end block 11 is installed, it can also limit the alignment of the end block 11 and the paper roll mounting rod 3, providing convenience for the user's disassembly and assembly work.
[0037] An adapter groove 17 is provided on one side of the top of the outer shell 1. A clamping component 19 is movably installed inside the adapter groove 17. Both ends of one side of the adapter groove 17 are provided with grooves 18 that are adapted to the clamping component 19. A cutter 20 located outside the clamping component 19 is embedded inside the outer shell 1.
[0038] Specifically, the adapter slot 17, groove 18, and cutter 20 are designed as follows: the adapter slot 17 is used to install the clamping plate 191, the groove 18 is used to engage the spring piece 194, ensuring that the clamping assembly 19 can continuously clamp the paper, ensuring that the label roll can be unwound smoothly, and providing convenience for the user's work. The cutter 20 is used to cut the paper, and the top of the cutter 20 is set in a serrated shape to cut the paper.
[0039] The pressing assembly 19 includes a rotating pin 192 rotatably mounted in the adapter groove 17. A pressing plate 191 is fixedly mounted on the surface of the rotating pin 192. A rotating long rod 193 adapted to the label paper is embedded and rotatably mounted at the bottom of the pressing plate 191. A spring piece 194 adapted to the groove 18 is embedded at one end of each side of the pressing plate 191.
[0040] Specifically, the clamping component 19 is configured such that when pulling the paper roll head, the clamping component 19 is first lifted upwards, then the paper roll is pulled out and straightened, and then the clamping component 19 is pressed back into the adapter groove 17. Then the spring piece 194 will lock into the corresponding groove 18 to fix the clamping component 19 and prevent it from moving freely. Then the paper will pass over the surface of the rotating rod 193 below the clamping plate 191. At the same time, the rotating rod 193 will also rotate, which can also release the rolled paper and clamp it to prevent the paper from falling, so as to ensure that the paper can move smoothly and provide convenience for the user's work.
[0041] A stop block 16 is embedded in one side of the top of the outer casing 1, and two slots 15 adapted to the stop block 16 are provided on one side of the top of the outer casing 1.
[0042] Specifically, regarding the design of the card slot 15 and the stop block 16, the stop block 16 is installed in the two stop blocks 16 by plugging in. After the paper roll is installed, the stop block 16 is snapped onto the outer casing 1. This can limit the paper roll and ensure that the paper roll can always rotate and unwind within the outer casing 1, preventing the paper roll from shifting and providing convenience for the user's work.
[0043] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
