Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a chain drive mechanism for a labeling machine. Background Technology

[0002] Traditional labeling machines typically use conveyor belts or rollers to transport labeled products. During operation, these methods are prone to product misalignment due to factors such as the elastic deformation of the conveyor belt and asynchronous rotation of the rollers, affecting labeling accuracy. This positioning error is particularly pronounced at high speeds or when product specifications vary significantly, frequently resulting in misaligned or wrinkled labels, severely impacting packaging quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a chain drive mechanism for a labeling machine, which solves the problems mentioned in the background.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a chain drive mechanism for a labeling machine, comprising:

[0005] A ring-shaped frame with several gears rotatably connected inside;

[0006] A drive motor, mounted at the bottom of the annular frame, is used to drive one of the gears;

[0007] The chain is connected to the outside of several gears;

[0008] An annular guide rail is installed on the upper part of the annular frame.

[0009] Several labeling machine support stations are slidably set on the upper part of the circular guide rail and moved synchronously by chain drive;

[0010] The locking module is installed on the side of the ring frame and corresponds to each processing area of ​​the labeling machine, and can engage with any of the labeling machine's carrying stations.

[0011] Furthermore, the drive motor is a servo motor, which can intermittently drive several labeling machine carrier stations to move synchronously along the chain. When a certain labeling machine carrier station moves to the processing area of ​​the labeling machine, it stops moving and is locked by the locking module.

[0012] Furthermore, the distance that the drive motor drives the several labeling machine bearing stations to move each time is the distance between two labeling machine bearing stations.

[0013] Furthermore, the labeling machine's carrying station includes:

[0014] Base 1 is slidably mounted on the upper part of the annular guide rail;

[0015] The linkage plate is connected to one side of the base and is rotatably connected to the chain links via a snap ring;

[0016] The column is connected to the upper part of the base.

[0017] The support plate, connected to the middle of the column, is used to support the product to be labeled;

[0018] The limiting plate is connected to the top of the column and is located inside the ring-shaped product to limit the product's movement.

[0019] A protruding post connects to the other side of the base;

[0020] Several guide wheels are symmetrically connected to one end of the base, engaged on both sides of the annular guide rail and rolling along it.

[0021] Furthermore, the locking module includes:

[0022] Base 2 is installed on the side of the annular frame.

[0023] The locking drive cylinder is installed on the bottom outer side of the base.

[0024] The lifting plate is slidably connected to the top of the outer side of the base and is connected to the extension and retraction end of the locking drive cylinder.

[0025] A locking groove is pre-formed on the top of the lifting plate to engage with the outside of the protruding column;

[0026] The lifting guide rail is installed between the base and the lifting plate for sliding connection.

[0027] Furthermore, when the locking module needs to lock the labeling machine's bearing station, the locking groove engages with the outside of the protrusion to prevent the product on the labeling machine's bearing station from shifting during labeling machine processing.

[0028] This utility model provides a chain drive mechanism for a labeling machine. Compared with the prior art, it has the following advantages:

[0029] Beneficial effects:

[0030] The chain-driven mechanism of this labeling machine enables the cyclical transport of products to the carrying stations via a chain. Combined with the locking module, it precisely engages and locks the products in the processing area. This ensures efficient and orderly circulation of products between different stations while providing stable support during labeling, effectively preventing product deviation and shaking. It significantly improves the continuity and accuracy of labeling operations, greatly enhancing production efficiency and product quality. Attached Figure Description

Detailed Implementation

[0036] 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.

[0037] Please see Figure 1-4 This utility model provides a technical solution: a chain drive mechanism for a labeling machine, mainly used to drive several labeling machine bearing stations to move synchronously and lock the bearing stations in a specific processing area to ensure the stability of the ring-shaped products during the labeling process. The entire mechanism includes a ring frame, gears, a drive motor, a chain, a ring guide rail, labeling machine bearing stations, and a locking module, among other key components. These components work together to achieve efficient and stable labeling operations. Specifically...

[0038] The annular frame 1 serves as the supporting foundation for the entire mechanism, and several gears 2 are rotatably connected inside it. These gears 2 ensure smooth and accurate transmission through precise meshing.

[0039] One of the gears 2 is driven by a drive motor 3 (servo motor) mounted at the bottom of the annular frame 1. The drive motor 3 can work intermittently to precisely control the rotation angle and speed of the gear 2 according to the needs of the labeling operation. This is existing known technology and will not be described in detail here.

[0040] Several gears 2 are connected to a chain 4. Driven by the gears 2, the chain 4 can move circumferentially along the ring frame 1, thereby driving several labeling machine carrying stations 6 to move synchronously.

[0041] The annular guide rail 5 is installed on the upper part of the annular frame 1, providing sliding support for the labeling machine's bearing station 6. The design of the annular guide rail 5 ensures the stability and accuracy of the bearing station 6 during movement.

[0042] The labeling machine's carrying station 6 includes a base 61 that is slidably mounted on the upper part of the annular guide rail 5. A linkage plate 62 is connected to one side of the base 61. The linkage plate 62 is rotatably connected to the chain links of the chain 4 via a snap ring, thereby enabling the chain 4 to drive the carrying station 6.

[0043] The upper part of the base 61 is connected to the column 63, the middle part of the column 63 is connected to the bearing plate 64, and the top is connected to the limiting plate 65. The ring-shaped product to be labeled is placed on the bearing plate 64, and the limiting plate 65 is located inside the ring-shaped product to limit the product and prevent it from shifting during the labeling process.

[0044] On the other side of the base 61, a protrusion 66 is connected to engage with the locking module 7. Several guide wheels 67 are symmetrically rotatably connected to the bottom end of the base 61. The guide wheels 67 engage with both sides of the annular guide rail 5 and can roll along the annular guide rail 5 to ensure the smooth movement of the bearing station 6.

[0045] The locking module 7 is installed on the side of the annular frame 1 and corresponds to each processing area of ​​the labeling machine. The locking module 7 includes a base 2 71 installed on the side of the annular frame 1, and a locking drive cylinder 72 is installed on the bottom of the outer side of the base 2 71.

[0046] A lifting plate 73 is slidably connected to the top of the outer side of the base 2 71, and the extension and retraction end of the locking drive cylinder 72 is connected to the lifting plate 73. The lifting plate 73 can be moved up and down by the extension and retraction movement of the locking drive cylinder 72.

[0047] A locking groove 74 is pre-drilled at the top of the lifting plate 73. When it is necessary to lock the labeling machine bearing station 6, the locking drive cylinder 72 pushes the lifting plate 73 upward until the locking groove 74 engages with the protrusion 66, thereby locking the bearing station 6.

[0048] The base 71 and the lifting plate 73 are slidably connected by the lifting guide rail 75 to ensure the stability and accuracy of the lifting plate 73 during the up and down movement.

[0049] During operation, the device places the ring-shaped product to be labeled onto the carrier plate 64, ensuring that the limiting plate 65 is positioned inside the ring-shaped product for limiting. The drive motor 3 is then activated, driving the gear 2 to rotate, which in turn drives the chain 4. The chain 4 drives several labeling machine carrier stations 6 to move synchronously. When a ring-shaped product on a labeling machine carrier station 6 moves to the labeling area, the drive motor 3 stops, and the locking drive cylinder 72 pushes the lifting plate 73 upward until the locking groove 74 engages with the protrusion 66, locking the labeling machine carrier station 6. At this time, the ring-shaped product remains stable on the carrier plate 64, facilitating labeling. During the labeling process, the locking module 7 maintains a locked state on the carrier station 6 to ensure labeling accuracy. After labeling is completed, the locking drive cylinder 72 pushes the lifting plate 73 downward, releasing the locking groove 74 from the engagement with the protrusion 66. The drive motor 3 continues to drive the gear 2 to rotate, thereby driving the chain 4 to rotate, moving the labeling machine carrier station 6 and the ring-shaped product to the next processing area or the initial position.

[0050] Repeat the above steps to achieve cyclic operation of the labeling machine's chain drive mechanism. By precisely controlling the rotation angle and speed of the drive motor 3, as well as the locking and unlocking timing of the locking module 7, the efficiency and stability of the entire labeling operation can be ensured.
