Description

Technical Field

[0001] The utility model relates to the technical field of medical device production, in particular to a glue coating machine. Background Art

[0002] In the manufacturing of medical packaging bags, the gluing process is crucial. As a key piece of equipment in this process, the gluing machine is responsible for evenly applying glue to the surface of the bag, ensuring its sealing and protective properties. The gluing machine typically consists of a gluing roller and a bag-pressing roller, each typically driven by a cylinder. The gluing roller is responsible for evenly applying glue to the bag, while the bag-pressing roller is responsible for pressing the bag tightly against the gluing roller, ensuring a consistent gluing effect.

[0003] However, in existing gluing machines, the cylinder driving the bag-pressing roller is typically mounted directly on the gluing machine frame, and this mounting method only provides a side connection. Because the cylinder driving the bag-pressing roller is typically large, the strength of this side connection is relatively low, which can easily cause the cylinder to fall or become unstable during operation. Utility Model Content

[0004] The main purpose of the utility model is to provide a glue coating machine, aiming to solve the problem of low connection strength of the driving cylinder on the existing glue coating machine.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a gluing machine, which comprises:

[0006] frame;

[0007] a glue coating roller, rotatably mounted on the frame;

[0008] a bag pressing roller, rotatably mounted on the frame and disposed close to the glue coating roller;

[0009] A driving cylinder is connected to the bag pressing roller to drive the bag pressing roller to move closer to or away from the glue coating roller; and

[0010] The reinforcing structure is fixedly arranged on a side of the frame facing the bag pressing roller, and the base of the driving cylinder is fixedly arranged on the reinforcing structure.

[0011] In one embodiment, the reinforcement structure comprises:

[0012] A fixed shaft is provided on a side of the frame facing the bag pressing roller; and

[0013] A reinforcing plate is mounted on the fixed shaft and arranged toward the bag pressing roller, and a base of the driving cylinder is fixed on the reinforcing plate.

[0014] In one embodiment, the reinforcing plate is provided with a mounting portion, the mounting portion is provided on a side of the reinforcing plate facing the fixed shaft, and the fixed shaft is passed through the mounting portion to fix the reinforcing plate.

[0015] In one embodiment, the mounting portion is loosely fitted with the fixed shaft, and the reinforcement structure further includes a damping member disposed between an inner wall of the mounting portion and an outer wall of the fixed shaft to allow the reinforcement plate to rotate and stop at a target angle.

[0016] In one embodiment, the reinforcing plate is further provided with a plurality of reinforcing ribs, and the plurality of reinforcing ribs are protruding from a side of the reinforcing plate away from the driving cylinder.

[0017] In one embodiment, the reinforcing ribs include longitudinal ribs and transverse ribs, and the longitudinal ribs and transverse ribs are arranged to cross each other.

[0018] In one embodiment, the material of the reinforcement structure includes at least one of steel, metal and carbon fiber.

[0019] In one embodiment, the cylinder diameter of the driving cylinder ranges from 150 to 360 mm.

[0020] In one embodiment, the driving cylinder is located obliquely below one end of the bag pressing roller, and the driving cylinder is tilted toward the direction close to the bag pressing roller.

[0021] In one embodiment, the length of the glue coating roller and / or the bag pressing roller is greater than or equal to 100 cm.

The bag pressing roller is rotatably mounted on the frame and is disposed adjacent to the gluing roller. The arrangement of the bag pressing roller ensures that the packaging bag is aligned with the direction of the gluing roller, enabling the gluing roller to seal the packaging bag. The driving connection between the driving cylinder and the bag pressing roller can precisely control the movement of the bag pressing roller toward or away from the gluing roller, thereby precisely controlling the thickness and pressure of the glue applied by the gluing roller to the packaging bag, thereby ensuring consistency in the gluing effect. The reinforcement structure is fixedly mounted on the side of the frame facing the bag pressing roller, and the base of the driving cylinder is fixedly mounted on the reinforcement structure, making the frame more securely fixed to the driving cylinder. The driving cylinder can be fixed in both sides and bottom directions, and also helps to disperse and absorb the impact and vibration generated during the gluing process.

[0035] In existing gluing machines, the cylinder driving the bag-pressing roller is typically mounted directly on the gluing machine frame. This mounting method only provides a side connection. Because the cylinder driving the bag-pressing roller is typically large, this side connection is relatively weak, which can easily cause the cylinder to fall or become unstable during operation.

[0036] The utility model provides a glue coating machine.

[0037] See also Figure 1 and Figure 2 In one embodiment of the present invention, the glue coating machine 100 includes:

[0038] Rack 1;

[0039] The glue coating roller 2 is rotatably mounted on the frame 1;

[0040] The bag pressing roller 3 is rotatably mounted on the frame 1 and is disposed close to the glue coating roller 2;

[0041] The driving cylinder 4 is connected to the bag pressing roller 3 to drive the bag pressing roller 3 to move closer to or away from the glue coating roller 2; and

[0042] The reinforcement structure 5 is fixedly arranged on a side of the frame 1 facing the bag pressing roller 3 , and the base of the driving cylinder 4 is fixedly arranged on the reinforcement structure 5 .

[0043] In the technical solution of the present utility model, the gluing machine 100 includes a frame 1, a gluing roller 2, a bag pressing roller 3, a driving cylinder 4, and a reinforcement structure 5. The gluing roller 2 is rotatably mounted on the frame 1 and is used to apply glue and seal the packaging bag. The bag pressing roller 3 is rotatably mounted on the frame 1 and is disposed adjacent to the gluing roller 2. The arrangement of the bag pressing roller 3 ensures that the packaging bag is aligned with the direction of the gluing roller 2, allowing the gluing roller 2 to seal the packaging bag. The driving connection between the driving cylinder 4 and the bag pressing roller 3 can precisely control the movement of the bag pressing roller 3 toward or away from the gluing roller 2, thereby precisely controlling the thickness and pressure of the glue applied by the gluing roller 2 to the packaging bag, thereby ensuring the consistency of the gluing effect. The reinforcing structure 5 is fixed on the side of the frame 1 facing the bag pressing roller 3, and the base of the driving cylinder 4 is fixed on the reinforcing structure 5, so that the frame 1 can fix the driving cylinder 4 more firmly, and the driving cylinder 4 can be fixed in both the side and bottom directions, and it also helps to disperse and absorb the impact and vibration generated during the gluing process.

[0044] Specifically, there is no specific limitation on the specific structure of the reinforcing structure 5. For example, the reinforcing structure 5 can be a buffer seat that only supports the base of the driving cylinder 4. The reinforcing structure 5 can also be L-shaped, and the two sides of the L-shaped structure are used to fix the base and side of the driving cylinder 4 respectively, thereby further enhancing the fixing effect of the driving cylinder 4, making the overall structure more compact and reasonable, saving space, and improving the aesthetics of the equipment. It should be noted that there is no specific limitation on the specifications of the driving cylinder 4, and it can be selected and set according to the outer diameter of the bag pressing roller 3. In addition, in order to ensure the reinforcing effect of the reinforcing structure 5, the material of the reinforcing structure 5 can be a high-strength material such as fiberglass or metal alloy.

[0045] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 , the reinforcement structure 5 comprises:

[0046] The fixed shaft 51 is provided on the side of the frame 1 facing the bag pressing roller 3; and

[0047] The reinforcing plate 52 is mounted on the fixed shaft 51 and is disposed toward the bag pressing roller 3 . The base of the driving cylinder 4 is fixed on the reinforcing plate 52 .

[0048] Specifically, the reinforcing plate 52 is connected to the frame 1 via a fixed shaft 51. In this way, the inclination angle of the reinforcing plate 52 on the fixed shaft 51 can be adjusted, which is suitable for various installation angles of the bag pressing roller 3 on the frame 1 and has a wider adaptability. In addition, the reinforcing plate 52 serves as a mounting platform for the fixed shaft 51, which can provide stable support for the base of the driving cylinder 4, effectively enhancing the stability of the frame 1, ensuring a firm connection between the driving cylinder 4 and the bag pressing roller 3, and reducing the risk of loosening during operation. Optionally, the cross-sectional area of ​​the reinforcing plate 52 is larger than the cross-sectional area of ​​the base of the driving cylinder 4 so as to fully support the base as much as possible. In addition, the reinforcing plate 52 can also be fixed to the base of the driving cylinder 4 by multiple bolts. For example, a screw is separately provided at each of the four corners of the reinforcing plate 52 for threaded connection.

[0049] In the embodiments of the present invention, please refer to Figure 3 and Figure 4 , the reinforcing plate 52 is provided with a mounting portion 521, and the mounting portion 521 is provided on the side of the reinforcing plate 52 facing the fixed shaft 51, and the fixed shaft 51 is passed through the mounting portion 521 to fix the reinforcing plate 52. The reinforcing plate 52 is connected to the fixed shaft 51 through the mounting portion 521, so that the connection strength between the two is greatly improved, and the risk of equipment failure caused by loose connection during high-speed operation is reduced. The firm connection between the reinforcing plate 52 and the fixed shaft 51 helps to enhance the structural stability of the entire gluing machine 100, especially when subjected to large forces, it can effectively prevent the equipment from deformation. It should be noted that the mounting portion 521 can be a sleeve, and an extended arc-shaped connecting portion is provided at the connection between the sleeve and the mounting plate to ensure a stable connection between the sleeve and the mounting plate.

[0050] In the embodiments of the present invention, please refer to Figure 3 The mounting portion 521 is loosely matched with the fixed shaft 51, ensuring the precise positioning of the reinforcing plate 52 during the rotation process, so that it can rotate within a certain angle range, which is convenient for adapting to the installation angle and position of the bag pressing roller 3, and is used to match a variety of glue coating machines 100. The reinforcing structure 5 also includes a damping member, which is arranged between the inner wall of the mounting portion 521 and the outer wall of the fixed shaft 51. While reducing vibration and impact, the damping member reduces the wear between the fixed shaft 51 and the mounting portion 521, thereby extending the service life of the product. It also plays a buffering role during the rotation process, making the operation process smoother, so that the reinforcing plate 52 can quickly stabilize when rotating to the target angle, avoiding excessive rotation due to inertia, and improving the convenience and safety of operation. The damping member can be a damping sleeve or other structure that can generate damping.

[0051] In the embodiments of the present invention, please refer to Figure 4The reinforcing plate 52 is also provided with a plurality of reinforcing ribs 522, which protrude from the side of the reinforcing plate 52 facing away from the driving cylinder 4. The provision of multiple reinforcing ribs 522 enables the reinforcing plate 52 to withstand greater loads and is less likely to deform even when a larger driving cylinder 4 is installed, thereby effectively improving the overall rigidity of the reinforcing plate 52. By rationally designing the shape and distribution of the reinforcing ribs 522, the weight of the reinforcing plate 52 can be reduced without sacrificing strength and stability, allowing the reinforcing ribs 522 to absorb and disperse external impact forces, protecting the reinforcing plate 52 from damage. For example, the reinforcing ribs 522 can be elongated or wavy.

[0052] In the embodiments of the present invention, please refer to Figure 4 The reinforcing ribs 522 include longitudinal ribs 5221 and transverse ribs 5222. These ribs 5221 and 5222 are arranged in a cross pattern. This cross pattern helps evenly distribute stress, reducing stress concentration points and forming a three-dimensional grid-like structure. This reinforces the reinforcing plate 52 from multiple directions, significantly improving the strength and stability of the overall structure. It should be noted that in this embodiment, there is no specific limit on the number of longitudinal ribs 5221 and transverse ribs 5222, and they can be adjusted adaptively based on the shape of the mounting plate.

[0053] In the embodiment of the present invention, the reinforcement structure 5 is made of at least one of steel, metal, and carbon fiber. The appropriate material can be selected based on different application requirements. The reinforcement structure 5 can be any one of the above materials or a combination of these materials. The use of lightweight, high-strength materials such as carbon fiber can reduce overall weight without sacrificing strength. The use of stainless steel or other special metal materials can enhance the corrosion resistance of the reinforcement structure 5, making it suitable for long-term use in harsh environments.

[0054] In the embodiment of the present invention, the cylinder diameter of the driving cylinder 4 ranges from 150 to 360 mm. Driving cylinders 4 of different cylinder diameters can provide different thrust outputs. The cylinder diameter range of 150-360 mm means that a suitable cylinder can be selected according to the actual workload to ensure that the bag pressing roller 3 can be driven to operate smoothly and efficiently. The smaller cylinder diameter (150 mm) is suitable for occasions with limited space, while the larger cylinder diameter (360 mm) is suitable for environments requiring high thrust, covering a variety of application requirements from small to large equipment. Considering the large size and weight of the bag pressing roller 3, a matching driving cylinder 4 is required for matching.

[0055] In the embodiments of the present invention, please refer to Figure 1The driving cylinder 4 is located obliquely below one end of the bag pressing roller 3, and is tilted toward the bag pressing roller 3. Due to the tilted setting of the driving cylinder 4, the force transmission path is more direct, reducing the force loss caused by angle deviation, so that the bag pressing roller 3 can obtain more sufficient power. In this way, the bag pressing roller 3 can complete the bag pressing action more efficiently, which is more conducive to the efficient movement of the bag pressing roller 3 driven by the driving cylinder 4.

[0056] In the embodiments of the present invention, please refer to Figure 1 , the lengths of the gluing roller 2 and the bag pressing roller 3 are both set to be greater than or equal to 100 cm. In this way, longer materials can be processed at one time, the number of operation cycles is reduced, and the operating efficiency of the production line is significantly improved. In addition, the longer rollers can adapt to materials of different widths and lengths, and can also reduce the number of seams of the materials during the gluing and bag pressing processes, reduce the number of starts or stops of the gluing machine 100, and help save energy consumption. It should be noted that limiting convex rings can also be provided on the edges of both ends of the bag pressing roller 3. By sliding the limiting convex rings on the bag pressing roller 3, the packaging bag can be fixed in the desired position to prevent misalignment during the gluing process.

[0057] In the embodiments of the present invention, please refer to Figure 1 The bag pressing roller 3 is located obliquely below the gluing roller 2, and its installation height is lower than that of the gluing roller 2. This layout helps improve the overall compactness of the various mechanisms in the equipment, allowing the bag pressing roller 3 to better bring the packaging bag closer to the gluing roller 2, ensuring full contact between the gluing roller 2 and the gluing area on the packaging bag, thereby improving the sealing and firmness of the packaging.

[0058] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
