Description

Technical Field

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

[0002] In the field of labeling technology, the cleaning effect on the bottle before labeling directly affects the labeling quality and stability. If the bottle is not cleaned before operation with existing labeling machines, dust, debris, and other impurities can easily remain on the bottle surface. These impurities can cause the label to not adhere tightly to the bottle, resulting in problems such as bubbles, wrinkles, misalignment, or even detachment, directly causing labeling failure. This not only affects the consistency of the product's appearance but may also delay the production process and increase production costs.

[0003] To address this issue, some labeling equipment uses cleaning brushes or cleaning rollers for pre-treatment. However, these brushes and rollers are prone to scratching the bottle body, and over time, they continuously absorb impurities, forming a contamination layer. This not only significantly reduces their cleaning ability but also transfers impurities back to the bottle, causing secondary contamination. Furthermore, their disassembly and replacement processes are complex and maintenance costs are high, failing to meet the stable and efficient bottle cleaning requirements of continuous industrial production. Therefore, a pre-labeling cleaning mechanism that meets these cleaning needs is urgently needed. To this end, a pre-labeling cleaning mechanism for labeling machines is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning mechanism for a labeling machine before labeling, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning mechanism for a labeling machine before labeling, comprising a conveyor belt, a support frame installed on one side of the conveyor belt, threaded rods symmetrically installed on the side of the support frame near the conveyor belt, and support plates with arc surfaces on both sides fixedly installed on the threaded rods by nuts; The support frame is symmetrically rotatably connected to two drive shafts on the side away from the conveyor belt. A placement turntable for fixing the dust removal tape is installed on the top of the two drive shafts. The adhesive side of the dust removal tape faces outward and wraps around the front surface of the support plate. A sprocket is installed at the bottom of each of the two drive shafts, and a chain is installed between the two sprockets. A limiting mechanism for restricting the bottle body is installed on the other side of the conveyor belt.

[0006] Preferably, the limiting mechanism includes a limiting frame, a limiting screw is threadedly connected to the upper center of the limiting frame, one end of the limiting screw is rotatably connected to a limiting plate, and the limiting plate corresponds to the position of the support plate.

[0007] Preferably, limit rods are symmetrically installed on both sides of the limiting plate, and both limit rods are slidably connected to the limiting frame.

[0008] Preferably, the placement turntable includes a chassis, which is mounted on top of the drive shaft.

[0009] Preferably, a top plate is provided above the chassis, and a fixing bolt is installed between the top plate and the chassis.

[0010] Preferably, a motor is installed at the bottom of the support frame, and the motor is connected to the bottom end of a drive shaft.

[0011] Compared with existing technologies, the advantages of this invention are as follows: This cleaning mechanism cleans bottles by adhering the adhesive side of the dust-removing tape to the bottle body, avoiding the problem of traditional brushes scraping the bottle body. It can efficiently remove surface dust and other impurities, ensuring that the label adheres tightly to the bottle body, reducing bubbles, wrinkles, and peeling, and improving labeling quality and product appearance consistency. The synchronous rotation of the drive shaft driven by a motor, sprocket, and chain enables automatic conveying of the dust-removing tape. Combined with an adjustable limit mechanism and support plate, it adapts to different bottle sizes, meeting the needs of continuous industrial production. The turntable can be quickly disassembled and assembled with fixing bolts, facilitating maintenance and preventing the formation of a contamination layer on the cleaning components, thus reducing production costs and significantly improving cleaning efficiency and stability.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Please see Figure 1-6This utility model provides a technical solution: a cleaning mechanism before labeling a labeling machine, including a conveyor belt 1 for conveying the bottle body, a support frame 5 fixedly installed on one side of the conveyor belt 1, two threaded rods 8 symmetrically welded on the side of the support frame 5 near the conveyor belt 1, and support plates 4 with arc surfaces on both sides detachably installed on the threaded rods 8 by matching nuts.

[0016] On the side of the support frame 5 furthest from the conveyor belt 1, two drive shafts 10 are symmetrically connected via bearings. Each drive shaft 10 has a fixed top plate 3 for securing the dust-removing tape roll. The adhesive side of the dust-removing tape wraps around the front surface of the support plate 4, allowing it to adhere to the bottle surface on the conveyor belt 1. Each drive shaft 10 has a keyed bottom to a sprocket 9, and a chain 7 meshes between the two sprockets 9, enabling synchronous rotation of the two drive shafts 10. On the other side of the conveyor belt 1, a limiting mechanism 2 is fixedly installed to restrict the bottle's conveying position.

[0017] like Figure 5 As shown: The limiting mechanism 2 includes a limiting frame 21 fixed to the side of the conveyor belt 1. A threaded hole is provided in the upper center of the limiting frame 21. A limiting screw 22 is threadedly connected in the threaded hole. An arc-shaped limiting plate 23 is rotatably connected to the end of the limiting screw 22 near the conveyor belt 1 through a bearing. The limiting plate 23 is positioned corresponding to the support plate 4. Rotating the limiting screw 22 can push the limiting plate 23 closer to or away from the bottle body, and precisely adjust the limiting distance.

[0018] like Figure 5 As shown: Limiting rods 24 are symmetrically welded on both sides of the limiting plate 23. Both limiting rods 24 slide through the limiting frame 21. The limiting rods 24 slide synchronously with the limiting plate 23, limiting the movement direction of the limiting plate 23 and preventing it from deflecting.

[0019] like Figure 6 As shown: The turntable 3 includes a circular base 31, which is fixedly mounted on the top end face of the drive shaft 10. The upper surface of the base 31 is perpendicular to the drive shaft 10, providing a stable support base for the dust removal tape roll. A circular top plate 32 is provided above the base 31. A fixing bolt 33 is installed in the middle of the top plate 32 and the base 31. The fixing bolt 33 passes through the top plate 32 and is threadedly connected to the base 31, which can clamp and fix dust removal tape rolls of different thicknesses, facilitating disassembly and replacement.

[0020] like Figure 2 and Figure 3 As shown: The bottom of the support frame 5 is fixedly mounted with a motor 6 by a bracket. The output shaft of the motor 6 is fixedly connected to the bottom end of a transmission shaft 10 by a coupling. After the motor 6 is started, it can drive the transmission shaft 10 to rotate. Through the cooperation of the sprocket 9 and the chain 7, it drives another transmission shaft 10 to rotate synchronously, so as to realize the automatic conveying of the dust removal belt.

[0021] Working Principle: After the equipment is started, the conveyor belt 1 begins to transport the bottles to be labeled. The limiting screw 22 in the limiting mechanism 2 is rotated, pushing the limiting plate 23 towards the bottle until it forms a clamping distance with the support plate 4 that fits the bottle. The limiting rod 24 slides along the limiting frame 21, ensuring the limiting plate 23 moves stably without deflection. Simultaneously, the motor 6 at the bottom of the support frame 5 is started, driving the connected drive shaft 10 to rotate. This drive shaft 10 drives another drive shaft 10 to rotate synchronously via the bottom sprocket 9 and chain 7. The placement turntable 3 at the top of the two drive shafts 10 rotates accordingly, causing the dust-removing tape to be continuously transported along the arc surface of the support plate 4 with the adhesive side facing outwards. When the bottle on the conveyor belt 1 passes between the support plate 4 and the limiting plate 23, the dust-removing tape adheres tightly to the bottle surface, adhering to the dust and impurities on the bottle surface through the adhesive side of the tape, completing the cleaning before labeling. The cleaned bottle continues to be transported to the labeling station by the conveyor belt 1.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
