Description

Technical Field

[0001] This utility model relates to the field of trademark paper coating technology, and in particular to a cleaning module and a trademark paper coating device for packaging machines. Background Technology

[0002] The label paper gluing process is part of the label paper supply system. Pre-cut label paper is sucked down from the label paper magazine by a fan-shaped suction roller. The gluing mechanism evenly applies glue to the areas requiring gluing and then conveys it downwards to the predetermined position. The label paper gluing mechanism consists of a glue tank, a gluing roller, an applicator roller, and a scraper. The gluing roller applies glue lines at designated positions on the label paper during rotation. The amount of glue in the glue tank is controlled by a sensor. The glued label paper is conveyed to the predetermined position and folded with the cigarette pack containing the inner lining paper, including long-side folding, corner folding, and bottom folding. After folding, the label paper is dried by a soldering iron, and then the cigarette pack is pushed out by a pusher rod.

[0003] Currently, during the production process of the YB25 flexible box packaging machine, residual glue is generated by the coating roller during rotation and coating. The glue is repeatedly crushed on the roller surface to form glue residue. This glue residue is carried into the conveying channel by the label paper being conveyed, causing unstable label paper conveying and congestion, which ultimately leads to equipment failure and quality defects. Therefore, it is necessary to propose improvements. Utility Model Content

[0004] This utility model provides a cleaning module and a label paper coating device for a packaging machine to solve the problem of residual glue generated during the rotation and coating process of the coating wheel. The glue is repeatedly crushed on the wheel surface to form glue scale, which is carried into the conveying channel by the label paper during the conveying process, causing unstable label paper conveying and congestion, and ultimately leading to equipment failure and quality defects.

[0005] This utility model discloses a cleaning module, comprising: a mounting shaft, a cleaning component, and two limiting components, for mounting on a glue tank; the cleaning component includes a mounting part and a plurality of brushes, the brushes being distributed circumferentially around the outer periphery of the mounting part, the mounting part being rotatably sleeved on the mounting shaft; the two limiting components are both sleeved on the mounting shaft and are correspondingly located on both sides of the mounting part, the limiting components being fixedly connected to the mounting shaft, for limiting the cleaning component along the axial direction of the mounting shaft.

[0006] Optionally, the mounting shaft is detachably mounted on the glue tank via magnetic or bolt connection.

[0007] Optionally, two first fasteners are provided at opposite ends of the mounting shaft, and the two first fasteners are threadedly connected to the two ends of the mounting shaft to fix the mounting shaft on or remove it from the glue cylinder; a fixing nut is also provided on the first fastener.

[0008] Optionally, the limiting member is a positioning bushing, and a second fastener is provided on the positioning bushing. The second fastener connects the positioning bushing and the mounting shaft along one radial side of the positioning bushing.

[0009] Optionally, the length of the cleaning component is matched with the width of the surface to be cleaned on the coating wheel.

[0010] Optionally, a preset gap is maintained between the mounting part and each of the limiting members.

[0011] Optionally, the brush is evenly distributed on the mounting portion along the circumference of the mounting portion, and the brush is made of nylon or metal material.

[0012] This utility model also discloses a packaging machine label paper gluing device, including a glue cylinder, a gluing wheel, a glue-applying wheel, a scraper, and the cleaning module described above. The glue cylinder forms a receiving cavity with an opening. The glue cylinder, the gluing wheel, the glue-applying wheel, and the scraper are all located on the side of the glue cylinder near the opening. The mounting shaft of the cleaning module is located on the glue cylinder and on the same side as the gluing wheel. The brush abuts against the surface of the gluing wheel to be cleaned.

[0013] Optionally, the glue cylinder is provided with a fixing seat on both sides along its width direction, and a mounting notch is formed on the fixing seat, and the mounting shaft is detachably provided at the mounting notch.

[0014] Optionally, the mounting base is welded to the glue cylinder.

[0015] The beneficial effects of the cleaning module provided in this embodiment are as follows: the mounting shaft is used to mount on the glue tank, providing a stable mounting base for the entire cleaning module. When installing the mounting shaft, it is necessary to ensure that the brushes can contact the surface to be cleaned on the coating wheel. The mounting part of the cleaning component is rotatably sleeved on the mounting shaft, and several brushes are distributed circumferentially on its outer periphery. This structural design allows the cleaning component to rotate on the mounting shaft. When the coating device is running, the coating wheel rotates at high speed to perform the coating operation. The brushes contact the surface to be cleaned on the coating wheel and generate friction. As the coating wheel rotates, it drives the brushes to rotate as well. During this process, the brushes continuously sweep the surface to be cleaned on the coating wheel, promptly removing any newly generated residual liquid glue and any solid / semi-solid glue residue that is forming or has already formed. This reduces the possibility of glue residue entering the conveying channel, fundamentally reducing the probability of unstable and congested label paper conveying, improving the continuity and stability of the label paper coating device of the packaging machine, and thus reducing equipment failures and quality defects. The removed glue residue falls into the collection area inside the glue tank, preventing it from splashing or being carried away by the label paper. Two limiting components are fitted onto the mounting shaft and located on both sides of the mounting part, forming a limit on the cleaning component along the axial direction. This design can effectively prevent the cleaning component from shifting in the axial direction, ensuring that the brush always maintains an accurate contact position with the surface to be cleaned on the coating wheel, ensuring the accuracy of the cleaning range, avoiding the situation where some areas are not cleaned properly due to the shift of the cleaning component, further improving the cleaning effect, and ensuring the cleanliness of the coating wheel.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] This utility model embodiment provides a cleaning module, such as Figures 1 to 4 As shown, the device includes a mounting shaft 6, a cleaning component 5, and two limiting components 7. The mounting shaft 6 is mounted on the glue tank 1. The cleaning component 5 includes a mounting part 51 and several brushes 52. The brushes 52 are distributed around the outer periphery of the mounting part 51 along its circumference. The mounting part 51 is rotatably mounted on the mounting shaft 6. The two limiting components 7 are both mounted on the mounting shaft 6 and are located on opposite sides of the mounting part 51. The limiting components 7 are fixedly connected to the mounting shaft 6 and are used to limit the cleaning component 5 along the axial direction of the mounting shaft 6.

[0025] The mounting shaft 6 is mounted on the glue tank 1, providing a stable mounting base for the entire cleaning module. When installing the mounting shaft 6, it is necessary to ensure that the brush 52 can contact the surface to be cleaned on the coating wheel 2. The mounting part 51 of the cleaning component 5 is rotatably sleeved on the mounting shaft 6, and several brushes 52 are distributed circumferentially on its outer periphery. This structural design allows the cleaning component 5 to rotate on the mounting shaft 6. When the coating device is running, the coating wheel 2 rotates at high speed to perform the coating operation. The brushes 52 contact the surface to be cleaned on the coating wheel 2 and generate friction. When the coating wheel 2 rotates, it drives the brushes 52 to rotate as well. During this process, the brushes 52 continuously brush the surface to be cleaned on the coating wheel 2, removing the newly generated residual liquid glue and the solid / semi-solid glue residue that is forming or has already formed in a timely manner. This reduces the possibility of glue residue entering the conveying channel, fundamentally reducing the probability of unstable and congested label paper conveying, improving the continuity and stability of the label paper coating device of the packaging machine, and thus reducing equipment failures and quality defects. The removed glue residue falls into the collection area inside the glue tank 1, preventing it from splashing or being carried away by the label paper. Two limiting pieces 7 are fitted onto the mounting shaft 6 and located on both sides of the mounting part 51, limiting the cleaning piece 5 axially. This design effectively prevents the cleaning piece 5 from shifting in the axial direction, ensuring that the brush 52 always maintains an accurate contact position with the surface to be cleaned on the glue applicator 2, guaranteeing the accuracy of the cleaning range, avoiding situations where some areas are not cleaned properly due to the shift of the cleaning piece 5, further improving the cleaning effect, and ensuring the cleanliness of the glue applicator 2.

[0026] In this embodiment, the entire cleaning process is carried out automatically and continuously, accompanied by the adhesive application operation.

[0027] Reference Figure 4The coating wheel 2 has two surfaces to be cleaned. During the rotation of the coating wheel 2, the two surfaces to be cleaned alternately contact the cleaning part 5 and clean the surfaces to be cleaned.

[0028] As a preferred embodiment, the mounting shaft 6 is detachably mounted on the glue tank 1 via magnetic or bolt connection.

[0029] The aforementioned detachable configuration facilitates the installation and maintenance of the cleaning module on the glue tank 1. When the brush 52 wears out and needs to be replaced, the aforementioned detachable connection method can quickly disassemble and assemble the cleaning component 5, which is time-saving and has little impact on production.

[0030] The above magnetic connection can be achieved using existing magnetic components, and no specific limitations are made here; the above bolt connection can be achieved using existing threaded connections of screws or bolts, and no specific limitations are made here.

[0031] As a preferred embodiment, refer to Figures 1 to 3 The mounting shaft 6 is provided with first fasteners 9 at opposite ends. The two first fasteners 9 are threaded to the two ends of the mounting shaft 6 to fix the mounting shaft 6 on the glue cylinder 1 or remove it from the glue cylinder 1. The first fasteners 9 are also fitted with fixing nuts 11.

[0032] When the mounting shaft 6 is placed in the preset installation position of the glue cylinder 1, tightening the first fasteners 9 at both ends firmly fixes the mounting shaft 6 to the glue cylinder 1. The first fasteners 9 form an axial fastening to the mounting shaft 6 through a threaded connection, ensuring that the mounting shaft 6 will not shift or fall off during equipment operation (especially in environments with high-speed rotation of the glue applicator 2 and equipment vibration). The setting of the fixing nut 11 effectively solves the problem of loosening of the first fastener 9 caused by equipment vibration. In the high-speed production scenario of the YB25 packaging machine, continuous equipment vibration may cause the first fastener 9 to gradually loosen. However, the fixing nut 11, through its locking action with the first fastener 9, can maintain the fixed state of the mounting shaft 6 for a long time, avoiding poor contact between the cleaning part 5 and the glue applicator 2 due to the loosening of the mounting shaft 6, and ensuring the stability of the cleaning effect.

[0033] In this embodiment, the first fastener 9 can be a wing bolt. The two opposite ends of the mounting shaft 6 are formed with threaded holes that match the wing bolt along the axial direction. The wing bolt is designed to be easy to operate manually. No special tools are required for disassembly and installation, which facilitates the disassembly and assembly of the first fastener 9.

[0034] As a preferred embodiment, refer to Figures 1 to 3 The limiting component 7 adopts a positioning bushing, and a second fastener 8 is provided on the positioning bushing. The second fastener 8 connects the positioning bushing and the mounting shaft 6 along one radial side of the positioning bushing.

[0035] The tight fit between the positioning bushing and the mounting shaft 6, along with the radial locking of the second fastener 8, ensures that the position of the limiting member 7 on the mounting shaft 6 is accurate and stable, preventing axial displacement of the cleaning member 5 due to loosening of the limiting member 7. This design allows the brush 52 of the cleaning member 5 to always be aligned with the surface to be cleaned on the coating wheel 2, ensuring the accuracy of the cleaning range, avoiding localized cleaning omissions due to limiting failure, and further improving cleaning efficiency.

[0036] The second fastener 8 in this embodiment is not specifically limited, but an example of the second fastener 8 being a screw is given.

[0037] As a preferred embodiment, the length of the cleaning component 5 is matched with the width of the surface to be cleaned on the coating wheel 2.

[0038] By matching the length of the cleaning component 5 with the width of the surface to be cleaned, the brush 52 can completely cover the area of ​​adhesive residue on the surface to be cleaned in the axial direction, avoiding local adhesive residue caused by the cleaning component 5 being too short (such as adhesive residue not being removed from the edges of both ends of the applicator 2). This design ensures that all potential areas of adhesive residue formation on the surface of the applicator 2 can be effectively cleaned, fundamentally blocking the source of adhesive residue formation and further guaranteeing cleaning efficiency.

[0039] As a preferred embodiment, a preset gap is maintained between the mounting part 51 and each limiting member 7.

[0040] The preset gap setting avoids direct contact between the mounting part 51 and the limiting member 7. When the coating wheel 2 rotates and drives the cleaning part 5 (mounting part 51) to rotate, the mounting part 51 will not get stuck or resist due to friction with the limiting member 7, ensuring that the brush 52 can flexibly adjust the contact angle with the rotation of the coating wheel 2, thereby improving the uniformity of the cleaning effect.

[0041] The range of the preset gap can be 0.5mm-1mm, and no specific limit is made here.

[0042] As a preferred embodiment, the brushes 52 are evenly distributed on the mounting portion 51 along the circumference of the mounting portion 51, and the brushes 52 are made of nylon or metal.

[0043] The uniform circumferential distribution of the brush 52 ensures cleaning uniformity and improves cleaning efficiency. Both nylon and metal materials have good wear resistance (nylon is resistant to chemical corrosion, and metal is resistant to mechanical wear), and can maintain structural stability during long-term contact with adhesive and coating wheel 2, reducing the replacement frequency of brush 52 and lowering maintenance costs.

[0044] This application also discloses a packaging machine label paper gluing device, referring to... Figure 4The device includes a glue tank 1, a glue-applying wheel 2, a glue-applying wheel 3, a glue scraper 4, and the cleaning module described in the previous embodiment. The glue tank 1 forms a receiving cavity with an opening 101. The glue tank 1, glue-applying wheel 2, glue-applying wheel 3, and glue scraper 4 are all located on the side of the glue tank 1 near the opening 101. The mounting shaft 6 of the cleaning module is located on the glue tank 1 and on the same side as the glue-applying wheel 2. A brush 52 abuts against the surface of the glue-applying wheel 2 to be cleaned. This label paper glue-applying device for packaging machines has the same structure and beneficial effects as the cleaning module described in the previous embodiment. The structure and beneficial effects of the cleaning module have been described in detail in the previous embodiment and will not be repeated here.

[0045] In this embodiment, the cleaning module and the glue-applying wheel 2 are located on the same side, and the brush 52 directly abuts against the surface to be cleaned. This allows the glue-applying wheel 2 to be cleaned in real time while rotating and applying glue, forming a continuous "glue-cleaning" operation process. This collaborative working mode can remove glue residue before it dries and forms glue scale, preventing glue scale from accumulating on the wheel surface and fundamentally solving the glue scale problem in the prior art.

[0046] The cleaning module is fixed to the glue tank 1 via the mounting shaft 6, eliminating the need for large-scale modifications to the core components of the original glue application device (such as the glue application wheel 2, glue application wheel 3, and glue scraper 4), thus reducing the difficulty and cost of equipment upgrades. Furthermore, the layout of the new components is reasonable and will not interfere with the normal operation of the original functions such as glue application and glue application.

[0047] As a preferred embodiment, refer to Figure 3 and Figure 4 The glue cylinder 1 has a fixing seat 10 on both sides along its width direction. A mounting notch 102 is formed on the fixing seat 10, and the mounting shaft 6 is detachably located at the mounting notch 102.

[0048] The two fixed seats 10 form a symmetrical support structure, which can evenly distribute the weight of the mounting shaft 6 and the cleaning component 5 and the force during operation, preventing the mounting shaft 6 from bending or deforming due to unilateral force, ensuring stable contact pressure between the cleaning component 5 and the coating wheel 2, and improving the consistency of cleaning effect.

[0049] Reference Figure 3 In this embodiment, the installation notch 102 is a U-shaped opening.

[0050] Reference Figure 4 An example is given where the first fastener 9 is a wing bolt, and is threadedly connected to the mounting shaft 6 through the mounting notch 102. In this case, the fixing nut 11 is located inside the fixing seat 10 and abuts against the fixing seat 10.

[0051] As a preferred embodiment, the fixing seat 10 is welded to the glue tank 1.

[0052] The welding connection forms a rigid whole between the fixed seat 10 and the glue cylinder 1, which can resist external forces such as vibration during equipment operation and the force of the cleaning module, preventing the fixed seat 10 from loosening or shifting. During long-term, high-frequency production, the positional accuracy of the fixed seat 10 remains stable, ensuring that the mounting shaft 6 of the cleaning module and the cleaning component 5 are always in the preset working position, thus guaranteeing the continuity of the cleaning effect.

[0053] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
