AI Technical Summary
Traditional brush-type labeling technology cannot effectively overcome the deformation stress of hard labels, resulting in insufficient interfacial adhesion strength. Existing roller pressing devices have poor adaptability to curved workpieces, requiring manual post-processing, which increases production costs and extends production line cycle time.
A separate rotary label pressing device is adopted, which uses the coordinated movement of the sponge belt and the conveyor chain to rotate and roll the hard wine bottle. The label is pressed onto the curved surface of the hard wine bottle through the combined action of the sponge belt and the pressing plate.
This technology improves the pressing quality of labels on the curved surface of hard wine bottles, reduces labor intensity and production costs, increases production efficiency, and meets the needs of automated production.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of beverage packaging technology, and in particular to a detachable rotary label pressing device. Background Technology
[0002] In traditional paper label application processes, brush-type labeling technology can meet the labeling needs of flat products. However, when dealing with labels made of highly rigid plastic or metal materials, the contact pressure generated by conventional brush systems cannot effectively overcome the material deformation stress, resulting in insufficient interfacial adhesion strength and a tendency for edge warping.
[0003] Currently, while existing roller pressing devices can improve the clamping force of flat labels, their rigid contact structure has significant adaptation defects on curved workpieces, failing to achieve uniform pressure across the entire curved surface. Furthermore, the application of rigid labels to irregularly shaped surfaces in the industrial sector still relies on manual post-processing steps. This discrete operation mode not only extends production line cycle time but also significantly increases production costs due to increased labor intensity, severely restricting the efficiency improvement of automated production systems. Utility Model Content
[0004] To solve the above problems, this utility model discloses a detachable rotary marking device.
[0005] The specific plan is as follows:
[0006] A detachable rotary label pressing device, mounted on a base, is used to press the drip molding and label on the side of a wine bottle. It includes a pressing plate assembly and a belt assembly arranged front and rear. The pressing plate assembly includes a drip molding pressing plate and a label pressing plate arranged vertically. Both the drip molding pressing plate and the label pressing plate are horizontally arranged strips. The drip molding pressing plate presses against the upper half of the wine bottle, and the label pressing plate presses against the lower half of the wine bottle. The belt assembly includes two horizontally arranged sponge belts that press against the upper and lower sides of the wine bottle. Each sponge belt has a belt shaft assembly installed within it, and the belt shaft assembly is mounted on a belt assembly support rod. A horizontally arranged conveyor chain is located below the pressing plate assembly and the belt assembly. This conveyor chain transports the wine bottle and runs in the opposite direction to the sponge belts. The speed of the conveyor chain is greater than that of the sponge belts.
[0007] Furthermore, the bottle is a rigid bottle, consisting of a neck and a body. The neck is a vertical cylindrical surface, and the body is an outwardly convex arc surface. The neck and body are connected by a smooth curved surface. The drip-molded material is attached to the upper half of the side of the bottle, and the label is attached to the lower half of the side of the bottle.
[0008] Furthermore, the conveyor chain is fitted onto the conveyor chain support column.
[0009] Furthermore, both the drip molding pressing plate and the label pressing plate are provided with pressing plate support plates on their rear sides. The pressing plate support plates are installed in conjunction with the pressing plate up and down adjustment pillars, which are placed on the base.
[0010] Furthermore, a power motor is installed on the base, and the power motor drives the shaft in the belt shaft assembly to rotate by rotating the crankshaft.
[0011] Furthermore, guardrails are provided on both sides of the conveyor chain.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The overall structure is simple and the cost is low, which can effectively solve the waste of motion caused by alternating production on and off the production line, reduce labor intensity, save labor input costs, and improve production efficiency.
[0014] 2. By using the self-rotating rolling action of the sponge belt and the conveyor chain, the label (drip molding + label) on the curved surface of a hard wine bottle is pressed online, effectively improving the pressing quality. Attached Figure Description

Detailed Implementation
[0019] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0020] As shown in the figure, this utility model provides a detachable rotary label pressing device, installed on a base 11, for pressing the drip molding and label on the side of a wine bottle. It includes a pressing plate assembly and a belt assembly arranged front and rear. The pressing plate assembly includes a drip molding pressing plate 1 and a label pressing plate 2 arranged vertically. Both the drip molding pressing plate 1 and the label pressing plate 2 are horizontally arranged strips. The drip molding pressing plate 1 presses against the upper half of the wine bottle, and the label pressing plate 2 presses against the lower half of the wine bottle. The belt assembly includes two sponge belts 3 arranged vertically. Both sponge belts 3 are horizontally arranged and press against the upper and lower sides of the bottle. Each sponge belt 3 has a belt shaft assembly 4 installed within it, and the belt shaft assembly 4 is mounted on the belt assembly support rod 5. A horizontally arranged conveyor chain 10 is located below the pressing plate assembly and the belt assembly. The conveyor chain 10 is used to transport the bottle, and its running direction is opposite to that of the sponge belts 3. The running speed of the conveyor chain 10 is greater than that of the sponge belts 3, thus creating a continuous rubbing environment. For example, when the conveyor chain 10 moves the bottle from right to left, the sponge belts 3 rub against the bottle surface from left to right.
[0021] In this embodiment, the bottle is a rigid bottle, consisting of a neck and a body. The neck is a vertical cylindrical surface, and the body is an outwardly convex arc surface. The neck and body are connected by a smooth curved transition. The bottle is attached to the upper half of the side of the bottle with a drip-molded adhesive, and the label is attached to the lower half of the side of the bottle.
[0022] In this embodiment, the conveyor chain 10 is fitted onto the conveyor chain support column 6.
[0023] In this embodiment, both the drip molding pressing plate 1 and the label pressing plate 2 are provided with pressing plate support plates 7 on their rear sides. The pressing plate support plates 7 are installed on the pressing plate up and down adjustment pillars 13, which are placed on the base 11.
[0024] In this embodiment, a power motor 9 is installed on the base 11. The power motor 9 drives the shaft in the belt shaft assembly 4 to rotate by rotating the crankshaft 8.
[0025] In this embodiment, guardrails 12 are provided on both sides of the conveyor chain 10.
[0026] During production, bottles with pre-labeled labels enter the equipment at even intervals under the control of the inlet spacing controller. The conveyor chain drives the bottles, while a sponge belt applies slight pressure to the bottle neck and body, moving in the opposite direction to the chain. Because the conveyor chain's speed is greater than the sponge belt's rotation speed, the bottles continuously rotate towards the outlet within the tunnel. During this rotation, the soft material of the sponge belt increases friction with the bottle, causing it to rotate continuously. The rigid plastic pressing plate opposite the sponge belt, as the bottle rotates and contacts the pressing plate, applies pressure under stress. Because the pressing plate is made of plastic, scratches on the bottle are avoided.
[0027] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
