Description

Technical Field

[0001] This utility model relates to the field of labeling equipment technology, and in particular to a labeling machine with multiple locking structures for the material feeding component. Background Technology

[0002] Labeling machines are widely used in many industries such as food, pharmaceuticals, and daily chemicals. They achieve product identification by accurately affixing labels to the product surface. During the operation of the labeling machine, the feeding component is responsible for carrying and releasing the label roll, and its performance directly affects the working efficiency and labeling quality of the labeling machine.

[0003] Currently, the locking structures of the unloading components in labeling machines on the market are usually only compatible with specific types of label rolls. When changing to different types of label rolls, it is often necessary to replace the corresponding locking components, which is cumbersome, time-consuming, and seriously affects the continuity and efficiency of production. At the same time, some locking structures experience uneven force during the locking process, which can easily cause the label roll to shake or shift during unloading, thereby affecting the label feeding accuracy and reducing labeling quality.

[0004] Therefore, developing a locking structure for the feeding component of a labeling machine that can adapt to various types of label rolls, lock securely, and is easy to operate has become an urgent problem to be solved by those skilled in the art.

[0005] Therefore, the existing labeling equipment technology field needs further improvement. Utility Model Content

[0012] Furthermore, the locking part is arc-shaped and made of anti-slip material.

[0013] Furthermore, the synchronization control component includes a rotating component disposed on the side wall of the rotating side plate of the coil, a central through hole is provided in the middle of the coil mounting shaft, the central through hole is connected to the rotating component, a drive shaft is provided at the inner end of the radial push rod along the axial direction of the central through hole, a plurality of inclined guide grooves are provided on the rotating component, the inclined guide grooves are inclined from the inside to the outside of the rotating component, and the drive shaft is movably installed in a corresponding inclined guide groove.

[0014] Furthermore, the worm gear adjustment assembly includes a worm wheel disposed on the rotating member, and an adjusting worm is disposed on the rotating side plate of the coil, wherein the worm wheel and the adjusting worm mesh and drive each other.

[0015] In summary, the advantages of this utility model over the prior art are:

[0016] This invention addresses the shortcomings of existing labeling equipment technology. Through its structural design, it offers the following advantages: By incorporating multiple evenly distributed spreading components around the outer circumference of the roll mounting shaft, and under the action of a synchronous control component, it can lock label rolls of different inner diameters, adapting to various label roll models. This significantly improves the versatility and adaptability of the labeling machine's feeding component, eliminating the need for frequent replacement of locking components, saving replacement time, and increasing production efficiency. The synchronous control component engages with the drive shaft at the inner end of the radial push rod via an inclined guide groove on the rotating component. When the rotating component rotates, it drives multiple radial push rods to move synchronously along the radial guide holes, achieving synchronized action of multiple spreading components. This ensures uniform force on each locking part during the locking process, further improving the stability and reliability of the locking. The worm gear adjustment component uses a worm wheel and adjusting worm gear meshing transmission to control the rotation of the rotating component, featuring smooth transmission and good self-locking performance.

[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 Figures 1-5 This utility model provides a labeling machine with a multi-model locking structure for the material feeding component, including a roll rotating side plate 1, a roll mounting shaft 2 centrally located on the roll rotating side plate 1, multiple spreading components 3 disposed within the roll mounting shaft 2, a synchronization control component 4 connected to the multiple spreading components 3 disposed within the roll mounting shaft 2, a worm gear adjusting component 5 for controlling the synchronization control component 4 disposed on the roll rotating side plate 1, and a rotary drive component 6 connected to the roll rotating side plate 1; the roll rotating side plate 1 serves as a basic support structure, and the roll mounting shaft 2 at its center is used to install label rolls; the multiple spreading components 3 can synchronously extend and retract under the drive of the synchronization control component 4, thereby locking different models of rolls; the worm gear adjusting component 5 can control the action of the synchronization control component 4, and the rotary drive component 6 drives the roll rotating side plate 1 and the roll mounting shaft 2 to rotate, realizing the feeding of the rolls.

[0024] The rotating side plate 1 of this utility model includes a rotating mounting base 101. The rotating mounting base 101 is provided with an arc-shaped guide groove 102 with an angle greater than 180°. A rotating circular plate 103 is rotatably disposed in the arc-shaped guide groove 102. The rotating mounting base 101 in the rotating side plate 1 provides a mounting foundation for the whole. The arc-shaped guide groove 102 with an angle greater than 180° guides and limits the rotation of the rotating circular plate 103. The rotating circular plate 103 rotates in the arc-shaped guide groove 102, thereby driving the components such as the coil mounting shaft 2 to rotate synchronously, ensuring the stability of the unloading process.

[0025] In this invention, multiple spreading components 3 are evenly distributed around the outer circumference of the coil mounting shaft 2. This even distribution ensures that the locking force on the coil is evenly distributed circumferentially during coil tightening, preventing tilting or wobbling due to uneven force and ensuring stable coil installation.

[0026] The spreading assembly 3 of this utility model includes a radial guide hole 301 disposed on the coil mounting shaft 2. A radial push rod 302 is movably disposed in the radial guide hole 301. A locking part 303 is provided at the outer end of the radial push rod 302. When the spreading assembly 3 is working, the radial push rod 302 can move radially within the radial guide hole 301 of the coil mounting shaft 2. When the radial push rod 302 extends outward, the locking part 303 at its outer end contacts the inner wall of the coil and applies pressure to lock the coil. Conversely, when the radial push rod 302 retracts, the locking part 303 separates from the coil, and the coil can be removed or replaced.

[0027] The locking part 303 of this utility model is arc-shaped and made of anti-slip material. The arc-shaped locking part 303 can better fit with the inner wall of the roll material and increase the contact area. At the same time, the locking part 303 made of anti-slip material can increase the friction between the locking part and the roll material, further enhance the locking effect, and prevent the roll material from slipping during the unloading process.

[0028] The synchronous control component 4 of this utility model includes a rotating component 401 disposed on the side wall of the coil rotating side plate 1. A central through hole 402 is provided in the middle of the coil mounting shaft 2, which connects to the rotating component 401. A drive shaft 403 is provided at the inner end of the radial push rod 302 along the axial direction of the central through hole 402. Multiple inclined guide grooves 404 are provided on the rotating component 401. The inclined guide grooves 404 are inclined outwards from the inner side of the rotating component 401. The shaft 403 is movably installed in a corresponding inclined guide groove 404. When the synchronous control component 4 is working, the rotating component 401 rotates, and the inclined guide groove 404 on it rotates accordingly. Since the drive shaft 403 is movably installed in the inclined guide groove 404, the inclined guide groove 404 will push or pull the drive shaft 403. The drive shaft 403 drives the radial push rod 302 to move in the radial guide hole 301, realizing the synchronous action of multiple opening components 3. The central through hole 402 provides space for the movement of components such as the drive shaft 403.

[0029] The worm gear adjustment assembly 5 of this utility model includes a worm wheel 501 disposed on the rotating member 401, and an adjusting worm 502 disposed on the rotating side plate 1 of the coil. The worm wheel 501 and the adjusting worm 502 mesh and drive each other. In the worm gear adjustment assembly 5, when the adjusting worm 502 rotates, the worm wheel 501 meshing with the adjusting worm 502 rotates accordingly. The worm wheel 501 drives the rotating member 401 to rotate. Through the transmission characteristics of the worm wheel and worm gear, precise control of the synchronous control assembly 4 is achieved, thereby adjusting the degree of opening of the opening assembly 3.
