Description

Technical Field

[0001] This utility model relates to a labeling machine, specifically, to a labeling machine with a feeding function. Background Technology

[0002] In the production process of many disc-shaped products such as cylindrical packaging boxes and bottle caps, it is often necessary to affix labels to their upper surfaces to indicate the brand, model or instructions for use. This type of operation requires extremely high precision and consistency in the labeling position.

[0003] Currently, manual placement or general-purpose labeling equipment is mostly used in production to complete this type of operation. However, manual operation has inherent instability: each time the operator picks up and places the product, it is difficult to maintain absolute consistency in the force, angle, and placement position. This randomness caused by manual operation makes it easy for the center position of the product to deviate from the theoretical center when it is placed at the labeling station, or for the product itself to be non-parallel to the workbench, which can easily cause it to shift at the labeling station. This results in inaccurate label placement on the upper side wall of the product, producing defects such as skewing and bubbling, which affects the product's appearance and quality control.

[0004] Even if general-purpose labeling equipment is used, the aforementioned problems of positioning accuracy and reliance on manpower cannot be fundamentally solved if it lacks a dedicated feeding and positioning mechanism. Ordinary equipment often lacks automatic, continuous feeding and precise positioning functions for disc-shaped products, and the timing of feeding, unloading and labeling actions is difficult to match precisely. This has become a bottleneck for improving overall production efficiency and pass rate and reducing labor costs. Utility Model Content

[0005] The purpose of this invention is to provide a labeling machine with a feeding function to solve the problems mentioned in the background art.

[0006] To address the above problems, this utility model aims to provide a labeling machine with a feeding function, including a base. Two support plates are fixedly installed on the upper sidewall of the base. A receiving plate is fixedly installed on the upper sidewall of the two support plates. A rotating shaft is coaxially mounted on the receiving plate. A turntable is coaxially fixedly installed on the upper end of the rotating shaft. The turntable is rotatably positioned within the receiving plate. Several arc-shaped grooves are arranged in a circular array on the outer circumference of the turntable. These arc-shaped grooves form a receiving cavity with the inner circumference of the receiving plate. Two through slots are symmetrically formed on the circumference sidewall of the receiving plate. A slide rail and a material cylinder are fixedly installed at positions corresponding to the two through slots on the outer circumference of the receiving plate. The interiors of the slide rail and the material cylinder are connected by corresponding... The through groove is connected to the inside of the receiving tray. A labeling head is provided on the upper side of the receiving tray between the slide and the material cylinder. The labeling head, slide, and material cylinder correspond to three receiving cavities. Several products are stacked inside the material cylinder. A guide sleeve is integrally formed on the side of the material cylinder away from the receiving tray. A push block is slidably installed inside the guide sleeve. A reciprocating mechanism and an intermittent rotation mechanism are provided on the lower side of the receiving tray. The reciprocating mechanism is used to drive the push block to move horizontally back and forth. The intermittent rotation mechanism is used to drive the rotating shaft to rotate intermittently. When the reciprocating mechanism drives the push block to move towards the receiving tray, the push block pushes the lowest product in the material cylinder into the corresponding receiving cavity through the through groove. Then, the intermittent rotation mechanism drives the rotating shaft to rotate by a predetermined angle.

[0007] As a further improvement to this technical solution, the reciprocating mechanism includes a mounting frame fixedly installed between two support plates. A speed reducer is fixedly installed on the lower side wall of the mounting frame. A servo motor for driving its input shaft to rotate is fixedly installed on the speed reducer. The output shaft of the speed reducer rotates through the mounting frame and is fixedly installed with an eccentric wheel.

[0008] As a further improvement to this technical solution, a sleeve frame is fitted on the outer side of the eccentric wheel, and guide grooves are opened on the side of the two support plates that are close to each other. The two sides of the sleeve frame are slidably disposed in the two guide grooves respectively. A connecting frame is fixedly installed on the sleeve frame, and the other end of the connecting frame is fixedly connected to the end of the push block away from the material cylinder.

[0009] As a further improvement to this technical solution, the intermittent rotation mechanism includes a positioning wheel coaxially fixed on the rotating shaft. The positioning wheel is located between the mounting frame and the receiving plate. The outer circumference of the positioning wheel is provided with a number of sliding grooves in an annular array. The number of sliding grooves is the same as the number of arc grooves.

[0010] As a further improvement to this technical solution, a locking groove is provided on the outer circumference of the positioning wheel at the position between two adjacent sliding grooves. A positioning disk is coaxially fixedly installed on the upper end of the reducer output shaft, and a crescent plate and a cylindrical block are fixedly installed on the upper side wall of the positioning disk.

[0011] As a further improvement to this technical solution, when the cylindrical block rotates into one of the sliding grooves, the crescent plate rotates out of the locking groove; when the cylindrical block rotates out of the sliding groove, the crescent plate rotates into one of the locking grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This labeling machine with feeding function uses a reciprocating mechanism to drive the pusher block to move horizontally back and forth, pushing the product at the bottom of the material cylinder into the receiving cavity formed by the turntable and the receiving plate, thus realizing automatic product feeding. Subsequently, the intermittent rotation mechanism drives the rotating shaft to rotate intermittently, causing the turntable and the product to move step by step, so that the product is accurately transferred to the labeling station below the labeling head, thereby automatically and stably placing the product in the labeling position. In this process, the linkage between the reciprocating mechanism and the intermittent rotation mechanism ensures that after the product is continuously pushed into the receiving cavity, it automatically steps to the labeling station, realizing automatic positioning and placement of the product in the labeling position, improving the automation level and efficiency of labeling.

[0015] 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.

[0016] Example 1 Please see Figure 1 As shown, the purpose of this embodiment is to provide a labeling machine with a feeding function, specifically used for labeling operations on the side wall of a disc-shaped product 6. It includes a base 1, two support plates 11 are fixedly installed on the upper side wall of the base 1, and a receiving plate 2 is fixedly installed on the upper side wall of the two support plates 11. A rotating shaft 4 is coaxially rotatably installed on the receiving plate 2, and a turntable 5 is coaxially fixedly installed on the upper end of the rotating shaft 4. The turntable 5 is rotatably disposed in the receiving plate 2, and the lower end of the rotating shaft 4 extends to the lower side of the receiving plate 2. A plurality of arc-shaped grooves 51 are formed in a ring array on the outer circumference of the turntable 5. The arc-shaped grooves 51 and the inner circumference of the receiving plate 2 form a receiving cavity for accommodating the product 6. The receiving cavity has a circular outline, and its inner diameter matches the outer diameter of the product 6 to ensure that the product 6 can be stably positioned.

[0017] Reference Figure 2 and Figure 3 Two through slots 23 are symmetrically opened on the circumferential sidewall of the receiving plate 2. A slide 21 and a material cylinder 22 are fixedly installed on the outer circumferential sidewall of the receiving plate 2 at the corresponding positions of the two through slots 23. The interior of the slide 21 and the material cylinder 22 are connected to the interior of the receiving plate 2 through the corresponding through slots 23. The slide 21 is designed as an inclined structure, with the end connected to the receiving plate 2 at a higher position. The material cylinder 22 is a cylindrical structure with an inner diameter that matches the outer diameter of the product 6. Its inner bottom side is at the same height as the inner bottom side of the receiving plate 2. Several products 6 are stacked inside the material cylinder 22. A guide sleeve 221 is integrally formed on the side of the material cylinder 22 away from the receiving plate 2. A push block 8 is slidably installed inside the guide sleeve 221. The upper surface of the push block 8 is flush with the upper surface of the lowermost product 6 in the material cylinder 22.

[0018] A labeling head 3 is provided on the upper side of the receiving tray 2 between the slide 21 and the material cylinder 22. The labeling head 3, the slide 21 and the material cylinder 22 correspond to three of the receiving cavities. When the product 6 rotates with the turntable 5 to the position corresponding to the labeling head 3, the labeling head 3 automatically applies a label to the upper side wall of the product 6. It should be noted that the labeling head 3 is a conventional component of the labeling machine, and its specific working principle will not be described in detail here.

[0019] A reciprocating mechanism 7 and an intermittent rotation mechanism 9 are provided on the lower side of the receiving tray 2. The reciprocating mechanism 7 drives the push block 8 to move horizontally back and forth, and the intermittent rotation mechanism 9 drives the rotating shaft 4 to rotate intermittently. When the reciprocating mechanism 7 drives the push block 8 to move toward the receiving tray 2, the push block 8 pushes the product 6 at the bottom of the material cylinder 22 into the corresponding receiving cavity through the through groove 23. Then, the intermittent rotation mechanism 9 drives the rotating shaft 4 to rotate by a predetermined angle, causing the turntable 5 and the product 6 on it to rotate synchronously. With each rotation, the product 6 moves to the position corresponding to the next receiving cavity. When the cavity containing the product 6 rotates to the position below the labeling head 3, the labeling head 3 automatically completes the labeling operation. The labeled product 6 then rotates with the turntable 5 to the position corresponding to the slide 21 and falls into the slide 21, sliding out along its inclined surface to complete the automatic unloading.

[0020] Throughout the entire work cycle, each time the turntable 5 rotates, the reciprocating mechanism 7 drives the pusher block 8 to complete one reciprocating motion. After the pusher block 8 pushes a product 6 into the receiving cavity, the turntable 5 rotates immediately, causing the empty receiving cavity to move to the corresponding position in the material cylinder 22. During this process, the pusher block 8 retracts, and the product 6 in the material cylinder 22 falls to the bottom under the action of gravity. Then the pusher block 8 moves again to push a new product 6 into the receiving cavity. This cycle is repeated to achieve continuous feeding and sequential labeling of all products 6 in the material cylinder 22, improving the automation level and labeling efficiency of the equipment.

[0021] The structure of reciprocating mechanism 7 is detailed below, referring to... Figures 4-6 The reciprocating mechanism 7 includes a mounting frame 71 fixedly installed between two support plates 11. A reducer 72 is fixedly installed on the lower side wall of the mounting frame 71. A servo motor 73 for driving its input shaft to rotate is fixedly installed on the reducer 72. The output shaft of the reducer 72 rotates through the mounting frame 71 and is fixedly installed with an eccentric wheel 74. A sleeve frame 75 is sleeved on the outer side of the eccentric wheel 74. A horizontally arranged guide groove 111 is opened on the side of the two support plates 11 that are close to each other. The two sides of the sleeve frame 75 are respectively slidably arranged in the two guide grooves 111, thereby restricting the sleeve frame 75 to move only in the horizontal direction. A connecting frame 76 is fixedly installed on the sleeve frame 75. The other end of the connecting frame 76 is fixedly connected to the end of the push block 8 away from the material cylinder 22.

[0022] When the servo motor 73 starts, its output shaft drives the reducer 72 to run. After the reducer 72 reduces the speed and increases the torque, the power is transmitted to its output shaft, which drives the eccentric wheel 74 to rotate. The eccentric wheel 74 pushes the inner wall of the sleeve frame 75, causing the sleeve frame 75 to move horizontally back and forth. Then, through the connecting frame 76, it drives the push block 8 to move synchronously, realizing the function of continuously pushing the product 6 inside the material cylinder 22 into the receiving cavity.

[0023] The structure of the intermittent rotation mechanism 9 is detailed below, referring to... Figure 7 The intermittent rotation mechanism 9 includes a positioning wheel 91 coaxially fixedly mounted on the rotating shaft 4. The positioning wheel 91 is located between the mounting frame 71 and the receiving plate 2. The outer circumference of the positioning wheel 91 is provided with a number of sliding grooves 92 in an annular array. The number of sliding grooves 92 is the same as the number of arc grooves 51. The outer circumference of the positioning wheel 91 is provided with locking grooves 93 at the positions between two adjacent sliding grooves 92. The upper end of the output shaft of the reducer 72 is coaxially fixedly mounted with a positioning plate 94. The upper side wall of the positioning plate 94 is fixedly mounted with a crescent plate 95 and a cylindrical block 96.

[0024] When the output shaft of the reducer 72 drives the eccentric wheel 74 to rotate, it synchronously drives the positioning disk 94, the crescent plate 95 and the cylindrical block 96 to rotate. When the cylindrical block 96 rotates into one of the slide grooves 92, it pushes the inner wall of the slide groove 92, drives the positioning wheel 91 to rotate, and then drives the rotating shaft 4 and the turntable 5 to rotate. When the cylindrical block 96 rotates out of the slide groove 92, the rotating shaft 4 stops rotating, completing a rotation of a predetermined angle. At this time, the crescent plate 95 rotates into the corresponding locking groove 93, and the positioning wheel 91 is restricted to rotate by the fitting structure, thereby locking the rotating shaft 4 and the turntable 5 in the current position. This design ensures that the pusher 8 has enough time to push the product 6 into the empty receiving cavity, and at the same time, the labeling head 3 can also complete the labeling operation on the corresponding product 6.

[0025] The contact surface between the crescent plate 95 and the locking groove 93 is arc-shaped, and the center of the arc surface is collinear with the axis of the output shaft of the reducer 72. This design ensures that the crescent plate 95 rotates smoothly and without interference when rotating into and out of the locking groove 93. In this locked state, the rotation trajectory of the cylindrical block 96 is aligned with the next slide groove 92, thus preparing for the next drive. As the output shaft of the reducer 72 continues to rotate, the cylindrical block 96 on the positioning plate 94 rotates into the next slide groove 92 again, thus starting a new round of drive cycle and realizing the intermittent movement of the turntable 5.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
