Abstract
Description
Technical Field
[0001] The utility model relates to the field of edge burr polishing treatment for paper components, in particular to a burr treatment device for paper tube cores. Background Art
[0002] In the field of non-woven fabric production, when the ribbon-shaped non-woven fabric after slitting is generally wound, the non-woven fabric is wound on a paper tube core. Finally, the storage of the non-woven fabric is completed. The paper tube cores used in this winding process are generally cut from a complete finished paper tube into multiple paper tube cores. This cutting process will cause the two cutting sides of the cut paper tube cores to have hard cutting burrs. During the process of winding the non-woven fabric, the cutting burrs on the high-speed rotating paper tube core will rub against the surface of the non-woven fabric, resulting in irregular scratches on the surface of the non-woven fabric. In severe cases, it will even tear the surface of the non-woven fabric, and the defective rate of the wound non-woven fabric roll will rise sharply. Moreover, during the winding process, the non-woven fabric is prone to shift to both sides after being stressed, resulting in a poor flatness of the side surface of the wound non-woven fabric roll. In severe cases, it even needs to be rewound to meet the winding requirements. Summary of the Invention
[0003] The purpose of the utility model is to provide a burr treatment device for paper tube cores with good burr polishing treatment effect and fast processing speed.
[0004] To solve the above technical problems, the utility model adopts the following technical solutions: A burr treatment device for paper tube cores includes an installation platform, an installation frame fixedly installed on the installation platform, and also includes a feeding frame, a pair of polishing wheels driven by a rotating motor to rotate at high speed for polishing, a moving clamping block cooperatively installed with the installation platform and driven by a polishing motor, and a static clamping block fixed on the installation frame. The feeding frame reciprocates from the initial position to below the static clamping block under the drive of a pushing motor. The feeding frame includes two main feeding plates arranged parallel to each other and longitudinally. A positioning area for positioning the paper tube core to be processed is provided on the main feeding plate. The distance between the main feeding plates is less than the maximum width of the paper tube core. The moving clamping block is located below the static clamping block and reciprocates from the initial position to the static clamping block under the drive of the pushing motor. A clamping space for clamping the paper tube core is formed between the moving clamping block and the static clamping block at the end position of the stroke, and the paper tube core is clamped. The maximum width of the moving clamping block is less than the distance between the main feeding plates. The polishing wheels reciprocate from the initial position to the position of the clamped paper tube core respectively under the drive of the polishing motor. A polishing groove for the area to be polished of the paper tube core to enter is opened on one side of the polishing wheel facing the paper tube core. When the high-speed rotating polishing wheel is at the end position of the stroke, the area to be polished of the paper tube core falls into the polishing groove, and the polishing motor drives the polishing wheel to rotate and translate to polish the area to be polished of the paper tube core.
[0005] Further, it further includes a loading inclined rack arranged on the inclined feeding rack. Two loading rails with an L-shaped longitudinal section are arranged on the loading inclined rack, and the positions of the two loading rails correspond to and cooperate with the feeding positions of the two main feeding plates. Each loading rail includes a horizontally formed part and a vertically formed part integrally formed. The horizontal parts of the two loading rails are fixedly connected to the upper surface of the loading inclined rack, and a loading groove for feeding the paper tube core is formed between the vertical parts of the two loading rails and the upper surface of a part of the loading inclined rack located between the two loading rails.
[0006] Further, the moving clamping block includes a left moving clamping piece and a right moving clamping piece that are fixedly connected to the pushing motor and move synchronously. The static clamping block includes a left static clamping piece and a right static clamping piece that are fixedly connected to the mounting rack. The left moving clamping piece and the right moving clamping piece are symmetrically arranged facing each other, and the included angle between the two clamping surfaces of the left moving clamping piece and the right moving clamping piece ranges from 60° to 120°. The left static clamping piece and the right static clamping piece are symmetrically arranged facing each other, and the included angle between the two clamping surfaces of the left static clamping piece and the right static clamping piece ranges from 60° to 120°.
[0007] Further, the surface of the clamping surface of the moving clamping block is an arc-shaped circular arc surface, and the surface of the clamping surface of the static clamping block is an arc-shaped circular arc surface corresponding to the surface of the clamping surface of the moving clamping block. A clamping area for fitting the outer side wall of a part of the paper tube core is formed between the surface of the clamping surface of the moving clamping block and the surface of the clamping surface of the static clamping block in the clamping state.
[0008] The beneficial effects of the present utility model are as follows: The present utility model quickly feeds the paper towel tube to be polished with rough edges through the feeding rack, clamps the paper tube core under the clamping cooperation of the moving clamping block and the static clamping block, and finally polishes the rough edge position of the paper tube core by a high-speed rotating polishing wheel. The cooperation process of the three actions is direct and efficient, and will not affect the integrity of the outer surface of the overall paper tube core. The paper tube core after rough edge treatment will not scratch or cut the surface of the non-woven fabric during the non-woven fabric winding process. The non-woven fabric winding process is smoother, the side surface of the wound non-woven fabric roll is flatter, the defective product rate is extremely low, and there are very few non-woven fabric rolls that need to be reworked and rewound, improving the production and processing efficiency.

[0014] In order to make the technical means, innovative features and functions achieved by the present utility model easy to understand, the present utility model will be further elaborated below.
[0015] As Figures 1 - 5 shown, the technical solution of the paper tube core burr treatment device of the present utility model includes an installation platform, an installation frame fixedly installed on the installation platform, and further includes a feeding frame 1, a pair of polishing wheels 2 driven by a rotating motor to rotate at high speed for polishing, a moving clamping block 3 cooperatively installed with the installation platform and driven by a polishing motor, and a static clamping block 4 fixed on the installation frame. The feeding frame 1 reciprocates from the initial position to below the static clamping block 4 under the drive of a pushing motor. The feeding frame 1 includes two main feeding plates arranged parallel to each other and longitudinally. A positioning area for positioning the paper tube core to be processed is provided on the main feeding plates. The distance between the main feeding plates is less than the maximum width of the paper tube core. The moving clamping block 3 is located below the static clamping block 4. The moving clamping block 3 reciprocates from the initial position to the static clamping block 4 under the drive of the pushing motor. A clamping space for clamping the paper tube core is formed between the moving clamping block 3 and the static clamping block 4 at the end position of the stroke, and the paper tube core is clamped. The maximum width of the moving clamping block 3 is less than the distance between the main feeding plates. The polishing wheels 2 reciprocate from the initial position to the position of the clamped paper tube core respectively under the drive of the polishing motor. A polishing groove for the to-be-polished area of the paper tube core to enter is formed on the side of the polishing wheel 2 facing the paper tube core. When the high-speed rotating polishing wheel 2 is at the end position of the stroke, the to-be-polished area of the paper tube core falls into the polishing groove. The polishing motor drives the polishing wheel 2 to rotate and translate to polish the to-be-polished area of the paper tube core. Two main feeding plates arranged parallel to each other and longitudinally send the paper tube core falling into the positioning area between the moving clamping block 3 and the static clamping block 4, and then the moving clamping block 3 driven by the pushing motor jacks up and cooperates with the static clamping block 4 to clamp the paper tube core, and finally the two cutting sides of the paper tube core are polished by the polishing wheels 2.
[0016] In the actual application process of the present utility model, since semi-automatic feeding of the paper tube core needs to be carried out manually, thus as Figure 2 and Figure 5As shown, in a preferred embodiment, it further includes a loading inclined rack provided on the inclined feeding rack 1. Two loading rails 5 with a longitudinal section in the shape of an L are provided on the loading inclined rack, and the positions of the two loading rails 5 correspond to and cooperate with the feeding positions of the two main feeding plates. The loading rail 5 includes an integrally formed horizontal part and a vertical part. The horizontal parts of the two loading rails 5 are fixedly connected to the upper surface of the loading inclined rack, and a loading groove for loading the paper tube core is formed between the vertical parts of the two loading rails 5 and the upper surface of the part of the loading inclined rack located between the two loading rails 5. The paper tube core to be loaded is limited and loaded through the loading rail 5, so that the loading process of the paper tube core is orderly and not prone to errors. During the process of feeding the paper tube core, two retaining columns driven by a driving motor and cooperating with the feeding rack 1 can also be installed at the discharging end position of the loading rail 5. One end of the retaining column is fixedly connected to the mounting rack, and the other end blocks or moves away from the discharging end of the loading rail 5 under the drive of the driving motor, ensuring that there is only one paper tube core being transported on the feeding rack 1, greatly reducing the possibility of feeding errors of the feeding rack 1, and avoiding multiple paper tube cores piling up on the two main feeding plates, resulting in the moving clamping block 3 being unable to accurately lift a paper tube core to be processed at the end position of the stroke of the two main feeding plates.
[0017] As Figures 3 - 5 shown, in an embodiment of the present invention, the clamping surface of the moving clamping block (3) is an arc-shaped circular arc surface, and the clamping surface of the static clamping block (4) is an arc-shaped circular arc surface corresponding to the clamping surface of the moving clamping block (3). A clamping area for fitting the outer side wall of a part of the paper tube core is formed between the clamping surface of the moving clamping block (3) and the clamping surface of the static clamping block (4) in the clamping state. The design of the clamping surface as an arc-shaped circular arc surface increases the contact area between the two clamping blocks and the outer side surface of the cylindrical paper tube core, making the clamping process more stable and not prone to loosening, avoiding the displacement of the paper tube core in the up and down directions, and ensuring that the paper tube core is always in a stable clamped state during the process of trimming the paper tube core. Of course, in the actual production process, there may also be cases where the paper tube core is non-cylindrical. At this time, the clamping blocks with the above structure cannot perform the trimming process normally. In another embodiment, the moving clamping block (3) includes a moving clamping left piece and a moving clamping right piece fixedly connected to the pushing motor and moving synchronously. The static clamping block (4) includes a static clamping left piece and a static clamping right piece fixedly connected to the mounting rack. The moving clamping left piece and the moving clamping right piece are symmetrically arranged facing each other, and the included angle range between the two clamping surfaces of the moving clamping left piece and the moving clamping right piece is 60° - 120°. The static clamping left piece and the static clamping right piece are symmetrically arranged facing each other, and the included angle range between the two clamping surfaces of the static clamping left piece and the static clamping right piece is 60° - 120°. Through the design of the left and right clamping pieces with different opening angles, it is convenient to clamp various non-regularly shaped paper tube cores, effectively improving the trimming efficiency of the paper tube core. And through the adjustment of the included angle between the clamping surfaces, the clamping and positioning of paper tube cores with different shapes and sizes can be realized on a set of equipment, avoiding the application of multiple sets of clamping equipment and effectively reducing the application cost.
[0018] Although the present utility model has been disclosed above with specific embodiments, it is not intended to limit the present utility model. Any person skilled in the art can still make some modifications and refinements without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be determined by the scope defined in the appended claims.
