Technical Field

[0001] This utility model relates to the technical field of label paper winding equipment, specifically a label paper tape winding device for self-adhesive printing machines. Background Technology

[0002] Self-adhesive label printing machine tape is a material used for printing self-adhesive labels. It typically consists of three layers: a face stock, adhesive, and a backing paper. The face stock can be paper, film, or other special materials, such as coated paper, thermal paper, or PET film, used for printing patterns and text. The adhesive bonds the face stock to the backing paper, giving it stickiness. The backing paper is usually silicone-coated protective paper, facilitating label peeling and pasting. Self-adhesive labels offer stable printing quality, clear patterns, and vibrant colors, ensuring product quality and aesthetics. They can be used for labeling and packaging various products, such as in the food, beverage, daily chemical, pharmaceutical, and electronics industries, demonstrating good adaptability and practicality. Self-adhesive label printing machine tape is widely used in industrial manufacturing, logistics and warehousing, power and telecommunications, supermarket retail, and other fields for printing product labels, price tags, anti-counterfeiting labels, barcode labels, etc.

[0003] After label paper production is completed, the take-up roller of the self-adhesive printing machine label paper tape winding device needs to be replaced. The new take-up roller is then used to continue winding the label paper. Currently, most take-up rollers require the removal of multiple fixing parts to detach them from the winding device, which is cumbersome and reduces the production efficiency of label paper. Therefore, there is an urgent need for a self-adhesive printing machine label paper tape winding device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a label paper tape winding device for self-adhesive printing machines, so as to solve the problem mentioned in the background art that most winding rollers require the removal of multiple fixing parts before the winding roller can be disassembled from the winding device, and the replacement of the winding roller is cumbersome, which reduces the production efficiency of label paper.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-adhesive printing machine label tape winding device, comprising a frame and a winding roller, wherein a rotating shaft is rotatably connected to the inner wall of the frame, and a clamp is connected to one end of the rotating shaft located inside the frame, a slot is provided on the inner side of the clamp, the end of the winding roller is located inside the slot, a sliding sleeve is slidably connected to the outer surface of the clamp, a stop is connected to the inner wall of the sliding sleeve, the outer surface of the stop is slidably connected to the inner wall of the slot, a limit mechanism is provided inside the clamp, a guide rod is connected to one side of the clamp, and a first spring is sleeved on the outside of the guide rod.

[0006] The number of guide rods is four, and the four guide rods are arranged in a circular array. The end of each guide rod away from the clamp is connected to a limit block.

[0007] One end of the first spring is connected to one side of the sliding sleeve, and the other end of the first spring is connected to one side of the limiting block.

[0008] A support frame is connected to one side of the frame, and a motor is installed on top of the support frame. The output shaft of the motor is connected to one end of the rotating shaft.

[0009] The limiting mechanism includes a mounting hole and a top rod. The mounting hole is located inside the chuck. A sleeve is slidably connected to the inner wall of the mounting hole. A second spring is connected to the inner bottom wall of the mounting hole. The other end of the second spring is connected to the inner top wall of the sleeve.

[0010] The clamp is equipped with a pressure ring inside, one side of which is in contact with the top end of the sleeve. One end of the push rod is connected to the top end of the sliding sleeve, and the other end of the push rod has an inclined angle.

[0011] The inner side of the stop block is provided with a stop groove, and the stop groove is adapted to the top rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The label tape winding device for a self-adhesive printing machine of this utility model, through the cooperation of a sliding sleeve, a stop block, a stop groove and a first spring, provides a receiving space for the winding roller through the slot, uses the sliding sleeve to control the movement of the stop block, controls the opening and closing of the slot's inlet and outlet through the moving stop block, and uses the first spring to provide elastic pushing force to the sliding sleeve, pushing the stop block into the slot so that the stop block is in a blocking state against the winding roller. When replacing the winding roller, it is not necessary to disassemble the fixed parts. It is only necessary to push the sliding sleeve to drive the stop block away from the slot, and the winding roller can be taken out from the slot, which improves the convenience of replacing the winding roller.

[0014] 2. The label tape winding device for a self-adhesive printing machine of this utility model utilizes the cooperation between a top rod, a second spring, and a stop groove. The second spring provides elastic pushing force for the top rod to contact the stop groove. After the stop block moves to a rearward position, the top rod contacts the stop groove, restricting the stop block from resetting. After the winding roller is replaced, the sliding sleeve is pushed to move the stop block forward, causing the stop block to block the entrance and exit of the slot. By restricting the movement of the stop block by the top rod, it is not necessary to constantly support the sliding sleeve to restrict the stop block's reset, thus improving the control function of the stop block.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 The present invention provides a self-adhesive printing machine label paper tape winding device, including a frame 1 and a winding roller 2. A rotating shaft 3 is rotatably connected to the inner wall of the frame 1. A clamp 4 is connected to one end of the rotating shaft 3 inside the frame 1. There are two rotating shafts 3 and clamps 4. The two rotating shafts 3 and clamps 4 provide support force to both ends of the winding roller 2 to maintain the stability of the rotating shaft 3.

[0024] A slot 5 is provided on the inner side of the chuck 4. The end of the take-up roller 2 is located inside the slot 5. The slot 5 is square in shape, and the end of the take-up roller 2 is also square. The square slot 5 and the end of the take-up roller 2 facilitate power transmission. A sliding sleeve 6 is slidably connected to the outer surface of the chuck 4. A stop 7 is connected to the inner wall of the sliding sleeve 6. The outer surface of the stop 7 is slidably connected to the inner wall of the slot 5. The stop 7 forms a block at the opening position of the slot 5, restricting the take-up roller 2 from disengaging from the inside of the slot 5.

[0025] A guide rod 9 is connected to one side of the chuck 4. A first spring 10 is sleeved on the outside of the guide rod 9. There are four guide rods 9 arranged in a circular array. A limit block 11 is connected to the end of the guide rod 9 away from the chuck 4. The guide rod 9 provides support for the sliding sleeve 6 and the first spring 10, maintaining the stability of the sliding sleeve 6 when it moves. The first spring 10 is supported by the guide rod 9 to prevent the first spring 10 from deforming and shaking when it elastically contracts, thus maintaining the stability of the first spring 10.

[0026] One end of the first spring 10 is connected to one side of the sliding sleeve 6, and the other end of the first spring 10 is connected to one side of the limiting block 11. The first spring 10 provides elastic support for the sliding sleeve 6 and the stop block 7, preventing the sliding sleeve 6 and the stop block 7 from disengaging from the end of the take-up roller 2. After the sliding sleeve 6 and the stop block 7 move to a new position, the first spring 10 is compressed. The compressed first spring 10 provides elastic pushing force for the sliding sleeve 6 and the stop block 7 to reset.

[0027] A support frame 12 is connected to one side of the frame 1, and a motor 13 is installed on the top of the support frame 12. The output shaft of the motor 13 is connected to one end of the rotating shaft 3. The support frame 12 provides support for the motor 13 to maintain the stability of the motor 13. The motor 13 serves as a power source to provide power for the rotation of the rotating shaft 3 and the take-up roller 2.

[0028] The chuck 4 is internally equipped with a limiting mechanism 8, which provides resistance to the stop 7 and prevents the stop 7 from automatically resetting. The limiting mechanism 8 includes a mounting hole 801 and a push rod 802. The mounting hole 801 is located inside the chuck 4. A sleeve 803 is slidably connected to the inner wall of the mounting hole 801. A second spring 804 is connected to the inner bottom wall of the mounting hole 801. The mounting hole 801 provides a space for the sleeve 803 and the second spring 804. The other end of the second spring 804 is connected to the inner top wall of the sleeve 803, providing an elastic pushing force to the sleeve 803. After the push rod 802 moves downward, the push rod 802 compresses the second spring 804 through the sleeve 803. The compressed second spring 804 provides power for the push rod 802 and the sleeve 803 to reset.

[0029] A pressure ring 805 is installed inside the chuck 4. One side of the pressure ring 805 contacts the top end of the sleeve 803. The pressure ring 805 restricts the movement of the sleeve 803 outside the mounting hole 801, thus confining the sleeve 803 inside the mounting hole 801. One end of the push rod 802 is connected to the top end of the sliding sleeve 6, and the other end of the push rod 802 has an inclined angle. The inclined push rod 802 facilitates contact with the stop block 7.

[0030] The inner side of the stop block 7 is provided with a stop groove 806, and the stop groove 806 is adapted to the push rod 802. The stop block 7 receives the resistance of the push rod 802 through the stop groove 806. After the stop block 7 slides backward, the stop block 7 compresses the push rod 802 to move downward. After the stop groove 806 moves to the stop groove 806 position, the push rod 802 moves upward under the push of the second spring 804. The push rod 802 contacts the stop groove 806, and the resistance of the push rod 802 restricts the movement position of the stop block 7.

[0031] Working principle: First, the sliding sleeve 6 is pulled backward. Simultaneously, the sliding sleeve 6 moves the stop block 7 backward, compressing the first spring 10. As the stop block 7 moves, it pushes the push rod 802 into the mounting hole 801. The push rod 802 simultaneously compresses the second spring 804 through the sleeve 803. Then, the stop groove 806 contacts the push rod 802, and the second spring 804, along with the sleeve 803, pushes the push rod 802 tightly against the mounting hole 801. The stop groove 806 remains in contact, and the push rod 802 provides resistance to the stop block 7 to reset the stop block 7. After the stop block 7 moves to a new position, it opens the entrance and exit of the card slot 5. Then, the winding roller 2 of the wound label paper is taken out from inside the card slot 5, and a new winding roller 2 is put into the card slot 5. Then, the sliding sleeve 6 is pushed to move to a new position. Under the action of the sliding sleeve 6, the stop block 7 pushes the push rod 802 to move downward to a new position. Then, the stop block 7 closes the entrance and exit of the card slot 5, confining the winding roller 2 inside the card slot 5.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
