[0027] In the production process of the papermaking industry, the rewinder is an important equipment in the post-processing section of the paper machine, and undertakes the key task of processing the products produced by the paper machine. In the rewinding operation, the paper core tube is needed to help the paper to be wound in the small roll bottoming link, and the paper core tube plays an indispensable role in the entire production process.

[0028] At present, 152.4mm paper core tubes are commonly used in the industry, and their use mode is mainly selected according to the length of the paper core tube. However, the rewinder has certain limitations in actual operation, and the minimum width specification of the normal paper winding is limited to 780mm. When the length of the 152.4mm paper core tube is shorter than 780mm, it cannot be normally used on the rewinder, and can only be discarded or used for other purposes, which causes great resource waste. In addition, some enterprises will process the paper core tubes that cannot be recycled on the rewinder at a low price or leave them idle, which not only wastes the capital investment of the enterprises in the early procurement of paper core tubes, but also increases the cost of the enterprises in the re-purchase of long paper core tubes. Due to the limitation of the length of the paper core tube and the minimum width specification of the rewinder, the short paper core tube cannot be reused, which causes resource waste, cost increase, production efficiency limitation and many other problems.

[0029] In view of the above problems, the exemplary embodiments of the present utility model provide a spliced paper core tube device to solve the problem of low utilization rate of paper core tubes in the prior art.

[0030] A steaming tower maintenance device according to the embodiments of the present utility model will be described in detail below with reference to the drawings.

[0031] Figure 1 The overall structure schematic diagram of the spliced paper core tube device according to the embodiments of the present utility model is shown in FIG. Figure 1 As shown in the figure, the spliced paper core tube device comprises a first end part 1, a partition 3 and a second end part 2, the partition 3 has a first port and a second port, the first port and the second port are oppositely arranged, the connecting end 5 of the first end part 1 is connected with the first port, and the connecting end 5 of the second end part 2 is connected with the second port; the protruding end 4 of the first end part 1 is provided as a boss structure, which is used for adaptively connecting the protruding end 4 of the first end part 1 with the paper core tube; the protruding end 4 of the second end part 2 is provided as a boss structure, which is used for adaptively connecting the protruding end 4 of the second end part 2 with the paper core tube.

[0032] In actual application, as Figure 1As shown, the partition 3 has a first port and a second port, the first port and the second port are oppositely arranged, the connecting end 5 of the first end part 1 is connected with the first port, and the connecting end 5 of the second end part 2 is connected with the second port. The partition 3 serves as an intermediate connecting component, and the first port and the second port thereof are connected with the first end part 1 and the second end part 2 respectively, so that the two paper core tubes can be connected with the first end part 1 and the second end part 2 and finally spliced. On this basis, the protruding end 4 of the first end part 1 is provided in a boss structure for adaptively connecting the protruding end 4 of the first end part 1 with the paper core tube, the protruding end 4 of the second end part 2 is provided in a boss structure for adaptively connecting the protruding end 4 of the second end part 2 with the paper core tube, and the protruding ends 4 of the first end part 1 and the second end part 2 are provided in boss structures. This design facilitates the adaptive connection with the paper core tube, and when disassembly is required, the boss structure facilitates the application of external force to pull it out of the paper core tube, facilitating the replacement of the paper core tube or the maintenance of the device, and effectively solving the problem of low utilization rate of the paper core tube.

[0033] For example, the outer surface of the partition is provided with anti-skid texture for increasing friction. The anti-skid texture is continuous and stripe-shaped and is uniformly distributed on the outer surface of the partition. It can be understood that the stripe-shaped anti-skid texture can be regular or irregular, which will not be described in detail here. Taking the regular stripe shape as an example, the depth and spacing of the stripe shape are uniformly distributed, which can increase the friction between the partition and the end part of the paper core tube, prevent the relative sliding of the paper core tube during rewinding, and will not cause damage to the end part of the paper core tube. In addition, the anti-skid texture is manufactured by an integrated forming process and is formed by special treatment of the mold surface during injection molding, which ensures the quality and stability of the anti-skid texture. Secondly, the surface of the anti-skid texture is treated to be smooth to avoid scratching or static electricity when contacting the paper core tube, ensuring the surface quality of the paper core tube and the splicing effect.

[0034] For example, the radial dimension of the partition is 178mm-178.8mm, and it can be understood that the consistency of the outer diameter of the partition and the outer diameter of the paper core tube is ensured within the above tolerance range. The thickness of the partition is 5mm, which can provide effective partitioning during the splicing of the two paper core tubes, accurately butt joint the two paper core tubes, and provide sufficient support force for the spliced long tube during the operation of the rewinding machine, prevent the spliced part from shifting or shaking, and ensure the stability and accuracy of the rewinding operation.

[0035] Exemplarily, the outer diameter of the first end portion is smaller than the inner diameter of the paper core tube, and the outer diameter of the second end portion is smaller than the inner diameter of the paper core tube, and the axial dimension of the first end portion and the second end portion is 100 mm. In practical application, when the first end portion of the splicing paper core tube device and the second end portion of the splicing paper core tube device are respectively inserted into two short paper core tubes and the paper core tube end heads abut against the middle partition, the stable splicing of the two short paper core tubes can be realized, and the long tube after splicing can be kept stable during the operation of the rewinder, and can be used as a whole tube. At the same time, the axial dimension of the first end portion and the second end portion is 100 mm, which should be understood as the length of the first end portion and the length of the second end portion, which can ensure that the first end portion and the second end portion can form sufficient contact area with the inner wall of the paper core tube after being inserted into the paper core tube, thereby providing reliable connection strength.

[0036] Exemplarily, the outer diameter of the boss structure gradually increases in the direction from the protruding end of the first end portion to the connecting end of the first end portion. The outer diameter of the boss structure away from the connecting end of the first end portion is 144 mm.

[0037] In practical application, the outer diameter of the boss structure gradually increases in the direction from the protruding end of the first end portion to the connecting end of the first end portion. In fact, the outer diameter of the first end portion and the outer diameter of the second end portion are both 153.8 mm-154.2 mm, the outer diameter of the first end portion and the outer diameter of the second end portion are respectively matched with the inner diameter of the paper core tube, and the outer diameter of the boss structure away from the connecting end of the first end portion is 144 mm, which ensures the close fit of the first end portion and the second end portion with the inner wall of the paper core tube within the tolerance range. It is helpful for the first end portion and the second end portion to be more smoothly inserted into the paper core tube, effectively reduces the resistance during insertion of the first end portion and the second end portion, avoids damage to the inner wall of the paper core tube caused by hard friction during the insertion process of the first end portion and the second end portion, and ensures the integrity and reusability of the paper core tube. At the same time, this boss structure significantly improves the convenience and efficiency of splicing operation, and the operator can complete the insertion of the end head without applying excessive force, thereby reducing the labor intensity.

[0038] Exemplarily, the splicing paper core tube device is a hollow structure, which can reduce the cost of raw materials while ensuring the basic function of the splicing paper core tube. It should be understood that the wall thickness of the first end portion and the wall thickness of the second end portion are both 9 mm, which can ensure the close connection between the first end portion and the second end portion and the paper core tube, ensure the sufficient structural strength of the splicing paper core tube device, prevent the splicing paper core tube device from loosening due to the tension of the rewinder during the winding process, and also ensure that the splicing paper core tube device can withstand the stress caused by frequent insertion and removal operations, thereby avoiding deformation or damage during use.

[0039] Exemplarily, the spliced paper core tube device is made of wear-resistant material, and it should be understood that the wear-resistant material is specifically polyamide, polycarbonate or polyoxymethylene, etc. plastic with good comprehensive performance, which has good toughness and fatigue resistance, and can not be broken or damaged when bearing the vibration and impact force generated during the working process of the rewinder. Moreover, the material can effectively resist the friction and wear of the inner wall of the paper core tube and the corrosion of external environmental factors during multiple cycles, prolong the service life of the device, and reduce the replacement cost and downtime caused by device damage.

[0040] The above description is only some embodiments of the present application and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above utility model concept. For example, the above features and the technical features with similar functions in the utility model (but not limited to) are replaced with each other to form a technical solution.

[0041] Although some specific embodiments of the present application have been described in detail through examples, those skilled in the art should understand that the above examples are only for illustration, not for limiting the scope of the present application. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
