Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper tube production equipment technology, and more specifically, to a paper tape gluing device. Background Technology
[0002] In the manufacturing process of paper tubes and other products, the tube winding process is a crucial step, and tube winding relies heavily on adhesive bonding. Therefore, a gluing device is needed to apply a precise amount of adhesive to designated locations on the paper tape. Current technologies commonly employ glue pumps to supply glue to nozzles or dispensing valves to the paper tape. However, these existing technologies have significant drawbacks: firstly, back pressure can arise due to the nozzle diameter, leading to leakage after the glue valve is closed; secondly, unstable pressure in the storage cylinder or air pressure can result in inconsistent glue dispensing, affecting the quality of subsequent tube winding – areas with insufficient glue will not bond properly, while areas with excessive glue will overflow, impacting the appearance. Furthermore, slow glue flow rates lead to low gluing efficiency, and air bubbles generated in the fluid also affect gluing quality. Additionally, the stability and reliability of existing gluing mechanisms are not high, causing numerous inconveniences in production. Therefore, a paper tape gluing device that can solve these problems is urgently needed. Utility Model Content
[0003] Based on the above-mentioned technical problems, this utility model proposes a paper tape gluing device.
[0004] A paper tape gluing device includes a glue supply system and a glue application device. The glue application device includes a mounting plate and a paper guide, a clutch roller, a glue application roller, a glue receiving roller, and a glue cylinder mounted on the mounting plate. The paper guide is used to guide the paper tape and align the center of the paper tape with the center of the glue application roller to ensure that the glue is accurately applied to a predetermined position on the paper tape. The clutch roller is located upstream of the glue application roller and is used to support the paper tape and can move up and down. When it is necessary to stop gluing, the clutch roller rises to lift the paper tape away from the glue application roller to avoid gluing. During normal operation, the clutch roller descends to make the paper tape contact the glue application roller. The glue receiving roller is arranged opposite to the glue application roller, and the two can transfer glue through roller contact. The glue receiving roller is partially immersed in the glue cylinder to pick up glue. The glue cylinder is used to store glue. The glue supply system includes a glue pump, a glue storage tank, and a conveying pipe. The glue pump pumps the glue in the glue storage tank to the glue cylinder through the conveying pipe.
[0005] Furthermore, the glue cylinder is equipped with a glue level detector. When the glue level reaches a predetermined position, the glue level detector sends a stop signal, and the glue pump stops supplying glue. When the glue level drops to a predetermined position, the glue level detector sends a start signal, and the glue pump starts supplying glue.
[0006] Furthermore, the surface of the gluing roller is provided with a long groove for accommodating glue. The position of the long groove corresponds to the predetermined glue application position on the paper tape, ensuring that the predetermined position is evenly coated with glue when the paper tape passes through the gluing roller.
[0007] Furthermore, the receiving roller and the applying roller are driven to rotate by a drive mechanism, which includes a motor and transmission components. The motor can control the receiving roller and the applying roller to rotate at low speed when the machine stops working to prevent the glue in the glue cylinder from solidifying. When the machine starts working again, the rollers will rotate at high speed to enter the normal working state.
[0008] Furthermore, the glue application device also includes a glue cylinder fixing mechanism, which is mounted on the mounting plate and includes a handle, a fixed arm, a lever arm, and an eccentric block. The fixed arm has an L-shaped structure, with its upper end hinged to the mounting plate. The lower part of the fixed arm supports the glue cylinder upwards. The middle part of the lever arm is rotatably mounted on the mounting plate via a pivot. The lower end of the lever arm supports the lower end of the fixed arm. The handle is connected to the pivot of the eccentric block. Rotating the handle causes the eccentric block to rotate, thereby locking or releasing the lower part of the fixed arm.
[0009] Furthermore, a scraper is provided on one side of the glue receiving roller. The scraper is used to scrape off excess glue from the surface of the glue receiving roller, further ensuring the accuracy of glue application.
[0010] Beneficial effects: 1. The method of using a receiving roller and an applying roller to transfer glue avoids the dripping problem caused by poor sealing when using valve body-type mechanisms for glue application; 2. The glue pump is automatically controlled by the glue level detector to ensure a stable glue level in the glue cylinder. Combined with the glue scraper to control the glue amount of the glue receiving roller, the glue application is uniform, which improves the quality of subsequent tube winding. 3. The drive mechanism controls the receiving roller and the applying roller to rotate at low speed when the machine is stopped, which prevents the glue from solidifying, reduces the cleaning and preparation time after the machine stops, and improves work efficiency.
[0011] 4. The mechanism is simple and reliable. All parts are mounted on the mounting plate, the structure is compact, and it can be easily inspected and cleaned through the handle, making maintenance convenient. Attached Figure Description

Detailed Implementation
[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0014] As shown in Figure 1-2, a paper tape gluing device is installed on the upright plate of the machine frame. The components are fixed by the mounting plate. During operation, the paper guide 1 is first adjusted so that the center of the paper tape 7 is aligned with the center of the gluing roller 4 to ensure that the glue is accurately applied to the predetermined position on the paper tape 7. The glue pump 9 operates to pump the glue in the glue storage tank 10 to the glue cylinder 8 through the conveying pipe. The glue level detector 11 monitors the glue level in the glue cylinder 8 in real time. When the glue level reaches the predetermined position, the glue pump 9 stops supplying glue; when the glue level drops to the predetermined position, the glue pump 9 restarts to supply glue.
[0015] like Figure 1 As shown, the direction of paper tape 7 is: paper guide 1 → clutch roller 2 → glue roller 4 → support roller 5 → adjusting roller 6 → subsequent process.
[0016] The receiving roller 3 is partially immersed in the glue cylinder 8 and picks up glue as it rotates. When the receiving roller 3 and the top glue roller 4 come into contact, the glue on the receiving roller 3 is transferred to the long groove on the surface of the top glue roller 4. The paper tape 7, supported by the clutch roller 2, passes through the top glue roller 4, and the glue in the long groove is evenly applied to the predetermined position on the paper tape 7. When an abnormality is detected or the machine stops working, the downstream support roller 5 of the top glue roller 4, in coordination with the rising of the clutch roller 2, lifts the paper tape 7 away from the top glue roller 4 and stops the glue application. At this time, the receiving roller 3 and the top glue roller 4 rotate at low speed to prevent the glue from solidifying.
[0017] The glue application device also includes a glue cylinder fixing mechanism, which is mounted on a mounting plate. This mechanism includes a handle 15, a fixed arm 16, a lever arm 17, and an eccentric block 18. The fixed arm 16 has an L-shaped structure, with its upper end hinged to the mounting plate. The lower part of the fixed arm 16 supports the glue cylinder 8 upwards. When the lower part of the fixed arm 16 rotates outwards, the fixed arm 16 releases its fixation to the glue cylinder 8, allowing the glue cylinder 8 to be detached. The lever arm 17 is rotatably mounted on the mounting plate via a pivot. The lower end of the lever arm 17 supports the lower end of the fixed arm 16. The handle 15 is connected to the pivot of the eccentric block 18. Rotating the handle 15 causes the eccentric block to rotate, thereby locking or releasing the lower part of the fixed arm 16. Figure 3As shown, the handle 15 is connected to the shaft of the eccentric block 18. When the handle 15 rotates, it can drive the eccentric block 18 to rotate. The rotation of the eccentric block 18 can drive the lower end of the lever arm 17 to rotate. When the lower end of the lever arm 17 deflects outward, it will release the lock on the fixed arm 16. At this time, the fixed arm 16 will release the fixation on the glue cylinder 8, so the glue cylinder 8 can be disassembled for maintenance and cleaning. Conversely, after the glue cylinder 8 has been cleaned and sent to the designated position, the lower part of the fixed arm 16 can be manually pushed upward to support it on the lower side of the glue cylinder 8. Then, the handle 15 is rotated, and the lower end of the lever arm 17 is used to lock the outer end of the lower part of the fixed arm 16, thus completing the fixed installation of the glue cylinder 8.
[0018] In addition, the glue receiving roller 3 is mounted on the glue cylinder 8, and the glue receiving roller 3 can be removed together for cleaning.
[0019] Downstream of the idler roller 5, there is also an adjusting roller 6, which is used to adjust the tension of the paper strip 7 when it enters the subsequent process.
[0020] In order to monitor the status of paper tape 7, the device also includes a paper tape 7 monitor. When the paper tape 7 is detected to be disconnected, the paper tape 7 monitor will issue an alarm and start the shutdown procedure to avoid glue coating abnormalities.
[0021] In order to remove excess glue from the surface of the receiving roller 3, a scraper 12 is provided on the lower side of the gluing roller 4. One end of the scraper 12 is mounted on a torsion bar 13, and an adjustable torsion spring is provided on the torsion bar 13. The torque of the torsion spring makes the scraper 12 adhere to the receiving roller 3 to ensure accurate glue application of the gluing roller 4.
[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
