Description

Technical Field

[0001] This utility model relates to the field of label printing and winding technology, specifically a winding device for finished label printing products. Background Technology

[0002] The final and crucial step in the label production process is the winding of printed label products. This involves neatly winding the continuous label materials, which have undergone printing, die-cutting, lamination, hot stamping, and other processing steps, onto a reel or paper core according to the set specifications, tension, and arrangement, to form a standard roll of finished product.

[0003] Chinese Patent Publication No. CN223162894U discloses a winding device for printed labels, comprising a base. Two first support plates, two second support plates, two third support plates, and two fourth support plates are fixedly connected to the upper surface of the base. Guide rollers are rotatably connected to the opposing side surfaces of the two first support plates. Two movable plates are slidably connected to the upper surface of the base. A plurality of limiting rollers are rotatably connected to the inner walls of the movable plates. Two brush rods are fixedly connected to the opposing side surfaces of the two second support plates. Two flattening rollers are rotatably connected to the opposing side surfaces of the two third support plates. A winding roller is rotatably connected to the opposing side surfaces of the two third support plates. Two limiting discs are slidably connected to the outer surface of the winding roller. This application can effectively limit the winding of printed labels of different sizes by using the limiting rollers and limiting discs together, preventing deviation during the winding process and thus improving the winding quality.

[0004] In the aforementioned prior art, the winding operation of the printed label can be achieved by controlling the rotation of the limiting roller and the limiting disk. However, the device does not have a method for removing the printed label after winding, which makes it inconvenient to remove the printed label after winding. In addition, the size of the winding tube that supports the mounting is fixed, making it inconvenient to adjust according to the size of the label winding tube.

[0005] In view of this, it is necessary to propose a rewinding device for finished label printing products to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a rewinding device for printed labels, in order to solve the problems mentioned in the background art, such as the lack of a means to remove the printed labels after rewinding, which makes it inconvenient to remove them after rewinding, and the fixed size of the rewinding tube, which makes it inconvenient to adjust according to the size of the label rewinding tube.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rewinding device for printed label products, comprising a base, two threaded slides slidably installed inside the base, each threaded slide having a movable frame mounted on it, two fixed frames mounted on the base, a limiting structure connecting the movable frame and the fixed frame on the same side, a transmission wheel rotatably installed inside each of the two fixed frames, a rotating structure connected to the two transmission wheels, and an adjustment structure connected to the two threaded slides.

A support rod is installed on one side of each T-shaped slider, and a rubber strip is installed on the support rod. A trapezoidal block is installed on one side of the support rod. Sliding rods are slidably installed inside the connecting shaft and the side baffle on the same side. Several trapezoidal blocks are installed on each of the two sliding rods. Trapezoidal blocks 1 and corresponding trapezoidal blocks 2 are in contact. An mounting frame is installed on one side of each movable frame and the fixed frame. An electric push rod is installed on one side of each mounting frame. The telescopic ends of the two electric push rods are rotatably installed on one end of each of the two sliding rods.

[0009] Preferably, the side baffle has several guide grooves inside, and the T-shaped slider is slidably installed in the corresponding guide groove. One end of a spring is installed on the inner wall of the guide groove, and the other end of the spring is installed on the T-shaped slider.

[0010] Preferably, a guide rod is installed on the inner wall of the guide groove, and the spring and the T-shaped slider are slidably sleeved on the guide rod.

[0011] Preferably, the telescopic end of the electric push rod is equipped with a limit shaft, which is rotatably installed inside the slide rod. The inner wall of the slide rod is provided with a strip groove, and a guide block is slidably installed in the strip groove. The guide block is installed on the inner wall of the side baffle.

[0012] Preferably, the rotating structure includes a dual-axis motor, which is mounted on a base. Both output ends of the dual-axis motor are equipped with transmission wheels two.

[0013] Preferably, the adjustment structure includes a geared motor mounted on a base, a bidirectional lead screw mounted on the output end of the geared motor, the bidirectional lead screw being rotatably mounted inside the base, two threaded slide blocks being symmetrically threaded onto the bidirectional lead screw, and two horizontal slide grooves being opened inside the base, with the two threaded slide blocks being slidably mounted in the two horizontal slide grooves respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) In use, the geared motor can be turned on to control the distance between the movable frames on both sides, so that the two ends of the roll sleeve of the label printing paper can be sleeved on the support rods on both sides. Then, the electric push rod can be turned on to control the support rod to expand outward and support and fix the inner wall of the roll sleeve. At this time, the dual-axis motor can be turned on to control the roll sleeves on both sides to rotate simultaneously, so as to perform the roll operation of the label printing paper. Two sets of roll sleeves can be controlled to perform the roll operation at one time. Furthermore, by controlling the movable frames on both sides to quickly move away from the fixed frame, it is convenient to take out the rolled label printing paper and replace the roll sleeve, thereby improving the roll efficiency.

Detailed Implementation

[0024] 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.

[0025] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a rewinding device for printed labels, including a base 100, two threaded slides 200 slidably installed inside the base 100, each of the two threaded slides 200 having a movable frame 201 installed on it, and two fixed frames 202 installed on the base 100. A limiting structure is connected to the movable frame 201 and the fixed frame 202 on the same side. The limiting structure is used to limit and fix the label rewinding roll. A transmission wheel 300 is rotatably installed inside each of the two fixed frames 202. A rotating structure is connected to the two transmission wheels 300, which is used to control the rotation of the fixed roll. An adjusting structure is connected to the two threaded slides 200, which is used to adjust the spacing of the limiting structures.

[0026] Furthermore, the limiting structure includes two connecting shafts 203, which are rotatably mounted inside the movable frame 201 and the fixed frame 202, respectively. A side baffle 204 is mounted on one side of each connecting shaft 203. Several T-shaped sliders 205 are slidably mounted inside the two side baffles 204. A support rod 206 is mounted on one side of each T-shaped slider 205. A rubber strip 212 is mounted on the support rod 206. A trapezoidal block 207 is mounted on one side of the support rod 206. Sliding rods 208 are slidably mounted inside the connecting shaft 203 and the side baffle 204 on the same side. Several trapezoidal blocks 209 are mounted on each of the two sliding rods 208. The trapezoidal blocks 207 and their corresponding... The trapezoidal blocks 209 are in contact with each other. Mounting brackets 211 are installed on one side of both the movable frame 201 and the fixed frame 202. Electric push rods 210 are installed on one side of both mounting brackets 211. The telescopic ends of the two electric push rods 210 are rotatably installed on one end of the two slide rods 208. When the electric push rods 210 are turned on, the slide rods 208 can be pulled to move. The moving slide rods 208 can drive several trapezoidal blocks 209 to press the inclined surface of the corresponding trapezoidal block 207, so that the trapezoidal blocks 207 around are pressed and drive several support rods 206 to move and expand outward at the same time, so that several support rods 206 can simultaneously drive the corresponding rubber strips 212 to press against the inner wall of the drum to support and fix it.

[0027] Furthermore, the side baffle 204 has several guide grooves 213 inside. The T-shaped slider 205 is slidably installed in the corresponding guide groove 213. One end of the spring 214 is installed on the inner wall of the guide groove 213, and the other end of the spring 214 is installed on the T-shaped slider 205. The inner wall of the guide groove 213 is installed with a guide rod 215. The spring 214 and the T-shaped slider 205 are slidably sleeved on the guide rod 215. When the support rod 206 moves, it will drive the T-shaped slider 205 to slide in the guide groove 213, so that the T-shaped slider 205 can slide on the guide rod 215 and compress the spring 214. When the trapezoidal block 209 is released from the pressure on the trapezoidal block 207, the compressed spring 214 will push the T-shaped slider 205 and the support rod 206 to move and reset.

[0028] Furthermore, a limiting shaft 216 is installed at the telescopic end of the electric push rod 210. The limiting shaft 216 is rotatably installed inside the slide rod 208. A strip groove 218 is provided on the inner wall of the slide rod 208. A guide block 217 is slidably installed in the strip groove 218. The guide block 217 is installed on the inner wall of the side baffle 204. When the telescopic end of the electric push rod 210 moves, it can pull the slide rod 208 to move through the limiting shaft 216. When the slide rod 208 rotates, it can rotate on the limiting shaft 216. When the slide rod 208 moves, it can slide on the guide block 217 through the strip groove 218. When the side baffle 204 rotates, it can drive the slide rod 208 to rotate through the cooperation of the strip groove 218 and the guide block 217.

[0029] Furthermore, the rotating structure includes a dual-axis motor 301, which is mounted on the base 100. Both output ends of the dual-axis motor 301 are equipped with transmission wheels 302. The same transmission belt 303 is mounted on the same side of the transmission wheels 300 and 302. The two transmission wheels 300 are respectively fixedly sleeved on corresponding connecting shafts 203. Turning on the dual-axis motor 301 controls the rotation of the transmission wheels 302. The transmission wheels 302 can drive the transmission wheels 300 to rotate via the transmission belt 303, causing the transmission wheels 300 to drive the connecting shafts 203 and the side baffle 204 to rotate. This, in turn, allows the side baffle 204 to drive the supported drum to rotate for winding.

[0030] Example 2: Figure 1To facilitate the removal of the wound-up drum and to adjust the spacing between the two support rods 206 according to the drum size, an adjustment structure is provided. The adjustment structure includes a geared motor 400, which is mounted on the base 100. A bidirectional lead screw 401 is installed at the output end of the geared motor 400. The bidirectional lead screw 401 is rotatably mounted inside the base 100. Two threaded slide blocks 200 are symmetrically threaded onto the bidirectional lead screw 401. Two horizontal slide grooves 402 are provided inside the base 100. The two threaded slide blocks 200 are slidably mounted in the two horizontal slide grooves 402 respectively. Turning on the geared motor 400 can control the rotation of the bidirectional lead screw 401. When the bidirectional lead screw 401 rotates, it can control the two threaded slide blocks 200 to move closer or further apart, thereby adjusting the spacing between the movable frames 201 and the fixed frames 202 on both sides. The remaining features are the same as in Embodiment 1.

[0031] The working principle is as follows: Turning on the geared motor 400 controls the rotation of the bidirectional lead screw 401. The threads at both ends of the bidirectional lead screw 401 face opposite directions, and each thread is adapted to one of the two threaded slides 200. Therefore, when the bidirectional lead screw 401 rotates, it controls the two threaded slides 200 to move closer or further apart, thereby adjusting the distance between the movable frames 201 and the fixed frame 202. First, the movable frame 201 is moved away from the fixed frame 202. Then, the roll of label printing paper is placed between the side baffles 204 on both sides. Finally, the movable frame 201 is moved closer to the fixed frame 202. The frame 202 allows the drum to fit onto the support rods 206 on both sides. At this time, activating the electric push rod 210 allows its telescopic end to pull the slide rod 208 via the limit shaft 216. The continuously moving slide rod 208 causes several trapezoidal blocks 209 to press against the inclined surfaces of the corresponding trapezoidal blocks 207. This pressure causes the surrounding trapezoidal blocks 207 to move and expand outwards simultaneously, allowing the support rods 206 to simultaneously press the corresponding rubber strips 212 against the inner wall of the drum for support and fixation. After the drum is fixed... One end of the label printing paper can be fixed to the roll. Turning on the dual-axis motor 301 controls the rotation of the second transmission wheel 302. The second transmission wheel 302 drives the first transmission wheel 300 to rotate via the transmission belt 303. This causes the first transmission wheel 300 to drive the connecting shaft 203 and the side baffle 204 to rotate. When the side baffle 204 rotates, it drives the slide rod 208 to rotate along with it through the cooperation of the slot 218 and the guide block 217. The slide rod 208 can then rotate on the limit shaft 216 to avoid interference with the electric push rod 210, thus allowing the side baffle 204 to... The rotating drum allows the label printing paper to be wound up. After winding, the output end of the electric push rod 210 is reset, which moves the slide rod 208 to reset and causes the trapezoidal block 209 to disengage from the trapezoidal block 207. At this time, the compressed spring 214 pushes the T-shaped slider 205 and the support rod 206 to reset, causing the rubber strip 212 to disengage from the support and fixation of the inner wall of the drum. Then, by controlling the movable frame 201 to move away from the fixed frame 202, the drum can be detached from the support rod 206 for easy removal.

[0032] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
