Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging technology, specifically to a paper tube surface scratch processing device and packaging machine. Background Technology
[0002] In packaging, logistics and other fields, paper tubes are a common packaging material, widely used due to their environmental friendliness, low cost, and ease of processing. However, traditional paper tubes have a relatively fixed shape, usually a regular cylinder, and the shape and size of their internal cavity are also relatively simple, making it difficult to meet the increasingly diverse product packaging needs.
[0003] As market demands for personalized and efficient product packaging continue to rise, the need for paper tubes capable of accommodating larger or oddly shaped items is becoming increasingly urgent. For example, when packaging irregularly shaped handicrafts or uniquely shaped electronic products, traditional paper tubes cannot fit snugly against the item's contours, wasting packaging space and potentially causing damage during transport due to movement. Furthermore, existing paper tubes lack sufficient capacity for packaging larger items, failing to achieve effective packaging. To address these issues, a feasible technical approach is to score the surface of the paper tube, deforming it into other shapes to expand the accommodating cavity.
[0004] Currently, most existing paper tube surface processing technologies focus on surface decoration processes such as printing and hot stamping. Research and equipment development related to scratching the surface of paper tubes to alter their shape are relatively limited. The few existing methods involving shape alteration suffer from low processing precision, complex operation, and difficulty in adapting to different paper tube sizes. For example, some manual scratching methods are not only inefficient but also struggle to ensure consistency in the location, number, and depth of scratches, leading to unstable paper tube deformation.
[0005] Based on this, a novel paper tube surface scratch processing device and packaging machine have been developed in this utility model, which has solved the above-mentioned technical problems. Summary of the Invention
[0006] One objective of this invention is to provide a paper tube surface scratching processing device. This device forms a groove structure by scratching the surface of the paper tube, which can deform the paper tube into other shapes, thereby expanding the cavity of the paper tube. This allows the paper tube to be used in packaging, logistics and other fields, enabling the paper tube to accommodate larger or special-shaped items, improving the practicality and functionality of the paper tube, and enhancing the market competitiveness of the product.
[0007] This utility model is achieved through the following technical solution:
[0008] A paper tube surface scratch processing device, comprising:
[0009] The work platform has an arc-shaped guide groove arranged circumferentially at its outer edge;
[0010] A paper tube support and rotation mechanism is installed in the middle of the working platform and is used to place the paper tubes to be processed.
[0011] Multiple scratching actuators are arranged around and spaced apart from the periphery of the paper tube support rotation mechanism; wherein, each scratching actuator includes a radial adjustment component for radial displacement adjustment, a longitudinal adjustment component for longitudinal displacement adjustment, and a scratching component, the radial adjustment component is installed at the arc-shaped guide groove of the working platform, the longitudinal adjustment component is installed on the radial adjustment component, and the scratching component is installed on the longitudinal adjustment component.
[0012] Furthermore, the paper tube support rotation mechanism includes a rotation drive assembly mounted on the working platform and a rotation frame rotatably mounted on the working platform. The rotation frame is connected to the rotation drive assembly in a transmission manner. The rotation drive assembly drives the rotation frame to rotate, and the rotation frame is used to carry the paper tube to be processed.
[0013] Furthermore, the radial adjustment assembly includes a radial drive unit mounted on the working platform and a linear slide module mounted on the working platform. The radial drive unit is connected to the linear slide module in a transmission manner to drive the slide table in the linear slide module to slide.
[0014] Furthermore, the longitudinal adjustment component includes a longitudinal support mounted on the sliding stage in the linear slide module along the longitudinal direction, a longitudinal slide rail mounted on the longitudinal support along the longitudinal direction, a slider slidably mounted on the longitudinal slide rail, and a longitudinal cylinder mounted on the longitudinal support. The telescopic end of the longitudinal cylinder is connected to the slider, driving the slider to slide along the longitudinal slide rail.
[0015] Furthermore, the longitudinal adjustment component also includes a speed regulator for controlling the sliding speed of the slider.
[0016] Furthermore, the scratching assembly includes a blade holder mounted on the slider and a scratching blade mounted within the blade holder.
[0017] Furthermore, the scratch-inducing mechanism is provided in three parts.
[0018] The beneficial effects of this utility model are:
[0019] The general working process of the paper tube surface scratch processing device in this utility model is as follows:
[0020] During the workstation adjustment stage: First, the installation position of the radial adjustment component can be adjusted using the arc-shaped guide groove to adjust the scratching actuator to the preset circumferential angle. Then, the paper tube to be processed is rotated to the target processing position using the paper tube support rotation mechanism, i.e., the target processing position is aligned with the scratching component.
[0021] Scratching process: When scratching, the radial adjustment component can be moved closer to the paper tube to be processed, and then the longitudinal adjustment component can be activated to drive the scratching component to reciprocate longitudinally, so as to achieve the scratching operation on the paper tube to be processed.
[0022] The paper tube surface scratching processing device of this utility model forms a groove structure by scratching the surface of the paper tube, which can deform the paper tube into other shapes, thereby expanding the accommodating cavity of the paper tube. This allows the paper tube to be used in packaging, logistics and other fields, enabling the paper tube to accommodate larger or special-shaped items, improving the practicality and functionality of the paper tube, and enhancing the market competitiveness of the product.
[0023] Furthermore, the arc-shaped guide groove on the outer edge of the work platform allows the radial adjustment component to move flexibly in the circumferential direction, enabling rapid and precise adjustment of the scratching actuator to a preset circumferential angle. Simultaneously, the radial and longitudinal adjustment components allow for radial and longitudinal displacement adjustment of the scratching component. On one hand, the radial adjustment component controls the distance between the scratching component and the paper tube surface, adapting to the processing needs of paper tubes with different diameters; on the other hand, the longitudinal adjustment component drives the scratching component to reciprocate longitudinally, achieving scratching operations along the paper tube's axial direction, forming multiple scratch groove structures on the paper tube's circumference. By controlling the position, number, and depth of the scratches, the paper tube can be deformed into various shapes to meet diverse product design requirements.

[0035] Paper tube support and rotation mechanism 2 is installed in the middle of the working platform 1 and is used to place the paper tube to be processed. In this embodiment, the paper tube to be processed is a cylindrical tube.
[0036] Multiple scratching actuators 3 are arranged around and spaced apart from the periphery of the paper tube support rotation mechanism 2. Each scratching actuator 3 includes a radial adjustment component 30 for radial displacement adjustment, a longitudinal adjustment component 31 for longitudinal displacement adjustment, and a scratching component. The radial adjustment component 30 is installed at the arc-shaped guide groove 10 of the working platform 1 to facilitate adjustment of the position of the radial adjustment component 30 in the circumferential direction of the working platform 1. The longitudinal adjustment component 31 is installed on the radial adjustment component 30, and the scratching component is installed on the longitudinal adjustment component 31.
[0037] The general working process of the paper tube surface scratch processing device in this utility model is as follows:
[0038] During the workstation adjustment stage: First, the installation position of the radial adjustment component 30 can be adjusted via the arc-shaped guide groove 10 to adjust the scratching actuator 3 to the preset circumferential angle. Then, the paper tube to be processed is rotated to the target processing position via the paper tube support rotation mechanism 2, i.e., the target processing position is aligned with the scratching component.
[0039] Scraping process: During scratching, the radial adjustment component 30 can be moved closer to the paper tube to be processed, and then the longitudinal adjustment component 31 can be activated to drive the scratching component to reciprocate longitudinally, thereby achieving the scratching operation on the paper tube to be processed. After processing, the paper tube structure is as follows. Figure 4 As shown.
[0040] The paper tube surface scratching processing device of this utility model forms a groove structure by scratching the surface of the paper tube, which can deform the paper tube into other shapes, thereby expanding the accommodating cavity of the paper tube. This allows the paper tube to be used in packaging, logistics and other fields, enabling the paper tube to accommodate larger or special-shaped items, improving the practicality and functionality of the paper tube, and enhancing the market competitiveness of the product.
[0041] Furthermore, the arc-shaped guide groove 10 on the outer edge of the working platform 1 allows the radial adjustment component 30 to move flexibly in the circumferential direction, enabling the scratching actuator 3 to be quickly and precisely adjusted to a preset circumferential angle. Simultaneously, the radial adjustment component 30 and the longitudinal adjustment component 31 allow the scratching component to be adjusted in both the radial and longitudinal directions. On one hand, the radial adjustment component 30 can control the distance between the scratching component and the paper tube surface, adapting to the processing requirements of paper tubes of different diameters; on the other hand, the longitudinal adjustment component 31 drives the scratching component to reciprocate longitudinally, achieving scratching operation along the paper tube axis, forming multiple scratch groove structures in the circumference of the paper tube.

Similarly, the specific structure of the rotation frame 21 is not limited in this utility model. It can be designed according to the shape of the paper tube to be processed, as long as it can support the paper tube to be processed and drive the paper tube to be processed to rotate synchronously.

It should be noted that the scratching assembly is not shown in the schematic diagram. Furthermore, this invention does not limit the specific structural form of the scratching knife; it can be designed and selected by those skilled in the art based on actual scratching requirements.
