A food can label pasting device

Abstract

This application relates to the technical field of can label pasting equipment, and more particularly to a food can label pasting equipment, including a conveyor belt with side guardrails on both sides. A drive system is located in the middle section of the conveyor belt, driving the canned jar to rotate at least one revolution inside the conveyor belt. A label peeling structure is located on one side of the drive system. The drive system includes a drive roller and a driven roller, which form a stable clamping structure to restrict the rotation of the canned jar inside the conveyor belt. By setting the drive system in the middle section of the conveyor belt, and utilizing the triangular structure formed by the drive roller and the driven roller, the canned jar is stably positioned inside the conveyor belt. Under the action of the drive roller, the canned jar rotates circumferentially, thereby enabling the canned jar to rotate in place, reducing the space required for labeling, and thus improving the practicality of the device.

Description

Technical Field

[0001] This application relates to the technical field of can label pasting equipment, and in particular to a food can label pasting equipment. Background Technology

[0002] In the field of automated food packaging production, can labeling is a crucial process for product identification, and the performance of the equipment directly affects production efficiency and labeling quality. Existing mainstream follow-up labeling equipment uses a track structure linked to the bottle's diameter, achieving circumferential label application through bottle rotation. However, this technology has significant drawbacks: when processing cans of different diameters, the length of the matching labeling track must be changed or adjusted synchronously to ensure the bottle completes a 360° rotation for label application. This design, reliant on adaptable mechanical track lengths, not only leads to frequent adjustments to the mechanical structure during equipment changeovers, increasing manual intervention costs, but also results in a cumbersome production line layout and low space utilization because different track specifications require separate storage and installation areas. Especially in multi-variety, small-batch production scenarios, frequent track changes and site switching severely restrict production flexibility, making it difficult to meet the demands of modern food processing enterprises for rapid changeovers and efficient production. Furthermore, the mechanical transmission accuracy of traditional follow-up structures is easily affected by track installation errors, potentially causing a missynchronization between bottle rotation and label supply, leading to quality problems such as label misalignment and wrinkles. Therefore, in order to solve the above problems, this application provides a food can label pasting device. Utility Model Content

[0003] To address the aforementioned problems, this application provides a food can label pasting device.

[0004] This application provides a food can label pasting device, including a conveyor belt with side guardrails on both sides. A drive system is provided in the middle section of the conveyor belt to drive the can bottle to rotate at least one revolution inside the conveyor belt. A label peeling structure is provided on one side of the drive system.

[0005] The drive system includes a driving roller and a driven roller, which form a stable clamping structure to restrict the rotation of the canned jar inside.

[0006] By setting up a drive system in the middle of the conveyor belt, the canned jars are stably placed inside the triangular structure formed by the active and driven rollers. Under the action of the active roller, the canned jars rotate in a circle, which enables the cans to rotate in place, thereby reducing the space required for labeling and improving the practicality of the device.

[0007] Preferably, the drive roller includes a roller that rotates on one side of the conveyor belt, and a motor is arranged below the roller.

[0008] Preferably, the driven roller includes a push plate and at least two auxiliary rollers on the push plate, with the auxiliary rollers and the rollers forming a bottle-covering structure.

[0009] Preferably, a support frame is welded to the external bracket of the conveyor belt, and a telescopic rod is fixedly connected to the support frame. The movable part of the telescopic rod is fixedly connected to the push plate.

[0010] Preferably, the label peeling structure includes a guide plate disposed on one side of the roller, and a rotating shaft is disposed at the end of the guide plate. The guide plate is used for peeling the label and the backing paper from each other.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By setting up a drive system in the middle of the conveyor belt, the canned jars are stably placed inside the triangular structure formed by the active and driven rollers. Under the action of the active roller, the canned jars rotate in a circle, which enables the cans to rotate in place, thereby reducing the space required for labeling and improving the practicality of the device.

[0016] The following is in conjunction with the appendix Figure 1 - Figure 2 This application will be described in further detail.

[0017] Example 1:

[0018] A food can label pasting device, as described in the following example Figure 1 - Figure 2 It includes a conveyor belt 1, with side guardrails 2 on both sides of the conveyor belt 1. A drive system is installed in the middle of the conveyor belt 1 to drive the canned bottles to rotate at least one revolution inside it. A label peeling structure is installed on one side of the drive system.

[0019] The drive system includes a driving roller and a driven roller, which form a stable clamping structure to restrict the rotation of the canned jar inside.

[0020] By setting a drive system in the middle of conveyor belt 1, the canned jars are stably placed inside the triangular structure formed by the active roller and the driven roller. Under the action of the active roller, the canned jars rotate in a circle, which enables the cans to rotate in place, thereby reducing the space required for labeling and improving the practicality of the device.

[0021] The active roller includes a roller 3 that rotates on one side of the conveyor belt 1. A motor 31 is installed below the roller 3. The motor 31 drives the roller 3 to rotate. By utilizing the friction between the roller 3 and the bottle body, the axial rotation of the bottle body is achieved, thereby realizing the labeling operation.

[0022] The driven roller includes a push plate 8 and at least two auxiliary rollers 9 on the push plate 8. The auxiliary rollers 9 and the roller 3 form a structure that covers the bottle body. The driving roller and the driven roller can form a triangular structure or other structures besides a triangle, as long as the bottle body position can be stabilized and its axial position can be kept stable.

[0023] A support frame 6 is welded to the external bracket of the conveyor belt 1. A telescopic rod 7 is fixedly connected to the support frame 6. The movable part of the telescopic rod 7 is fixedly connected to the push plate 8. After the bottle body moves into position, the telescopic rod 7 extends, and the auxiliary wheel pushes the bottle body and the roller 3 to stick together, so that the bottle body can rotate under the action of the roller 3.

[0024] The label peeling structure includes a guide plate 4 on one side of the roller 3, and a rotating shaft 5 is provided at the end of the guide plate 4. The guide plate 4 is used for peeling the label and the backing paper. The adhesive side of the peeled label paper faces the bottle body. When the bottle body passes through this position, the label will be pasted on it. With the help of the roller 3 and the auxiliary roller 9, complete pasting around the bottle body can be achieved.

[0025] The foregoing description of an exemplary embodiment of a food can label pasting device provided by this disclosure refers to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
