Description

Technical Field

[0001] The invention relates to the technical field of paper tube processing, in particular to a seamless paper tube grinding head device. Background Art

[0002] Paper tube is a kind of structural item which is made of paper as raw material and processed into a tube shape. It has a wide range of applications and is generally used as the inner core of winding products. After the raw materials are processed and cut into a tubular structure, in order to improve the smoothness of the cut surface, the paper tube needs to be installed on a grinding head machine and then ground to increase the smoothness of the cut surface of the paper tube and avoid burrs. When performing paper tube grinding head processing, existing equipment often requires manual placement of the paper tube on the grinding work surface. This method is inefficient and has poor safety. Some automated equipment is too complicated and costly, which is not very acceptable to enterprises. In addition, overly complicated equipment has high installation and debugging costs and is not very suitable for the production of paper tubes. Therefore, a seamless paper tube grinding head device is needed. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a seamless paper tube grinding head device for solving the problem of reducing manual operations when polishing the cross-section of a paper tube in the prior art.

[0004] To achieve the above objectives and other related objectives, the present invention provides the following technical solutions:

[0005] A seamless paper tube grinding head device comprises a frame, a limit assembly mounted on the frame, and a guide assembly arranged between the frame and both sides of the limit assembly;

[0006] The position limiting assembly comprises two groups of grinding head frames symmetrically arranged on the frame, an upper position limiting sleeve is arranged between the two groups of grinding head frames, and a lower position limiting sleeve capable of lifting and lowering movement is arranged below the position limiting sleeve;

[0007] The guide assembly includes limit plates arranged on both sides of the lower limit sleeve, the limit plates are slidably connected to the frame along the horizontal direction, the limit plates are inclined plates, and the height of the limit plates is gradually reduced in the direction away from the grinding head frame.

[0008] To implement the above technical solution, a grinding head frame is provided with an upper limit sleeve and a lower limit sleeve between two groups of grinding head frames to grind the edges of the paper tube. The upper limit sleeve and the lower limit sleeve cooperate to press the paper tube between the upper limit sleeve and the lower limit sleeve. The grinding device on the grinding head frame grinds the paper tube to ensure the stability of the paper tube during the grinding process. The polished paper tube moves with the lower limit sleeve under the drive of the lower limit sleeve and descends to the limit plate. Then, the paper tube slides out to the receiving end along with the inclination direction of the limit plate.

[0009] In one embodiment of the present invention, a material blocking ring is provided at the rear end of the limiting plate, and the opening of the material blocking ring is arranged in a direction away from the frame.

[0010] By implementing the above technical solution, the setting of the baffle ring can prevent the paper tube to be ground from sliding onto the grinding head frame during the grinding process, thereby ensuring the stability of the grinding process.

[0011] In one embodiment of the present invention, the limit plate is close to the lower limit sleeve at a height higher than the lowest point of the lower limit sleeve.

[0012] To implement the above technical solution, the limit plate is close to the height of the lower limit sleeve and higher than the horizontal height of the lowest point of the lower limit sleeve. The limit plate set in this way can lift the paper tube from the lower limit sleeve when the lower limit sleeve with the paper tube processed by the grinding head descends to the lowest point, and then the polished paper tube can slide off the limit plate.

[0013] In one embodiment of the present invention, the lower limiting sleeve is provided with a guide plate arranged along the inclination direction of the limiting plate.

[0014] To implement the above technical solution, the setting of the guide plate can facilitate the paper tube after the grinding process to be guided out along the tilting direction of the limit plate.

[0015] In one embodiment of the present invention, a cleaning air head is provided on the upper limit sleeve, and the blowing direction of the cleaning air head is arranged toward the abrasive working surface on the grinding head frame.

[0016] To implement the above technical solution, a cleaning air head is set, and the blowing direction of the cleaning air head is set toward the abrasive working surface on the grinding head frame, so that the debris generated during the grinding of the paper tube can be discharged to avoid accumulation on the grinding working surface and affect the subsequent paper tube grinding.

[0017] In one embodiment of the present invention, the upper limit sleeve and the lower limit sleeve are both arranged in a pseudo-tube type, the upper limit sleeve and the lower limit sleeve are arranged opposite to each other, and the lower limit plate rises to the highest point and is spaced apart from the upper limit plate.

[0018] To implement the above technical solution, the lower limit plate is raised to the highest point and set at a distance between the upper limit plate, which can provide sufficient supporting space for the paper tube. Both the upper limit sleeve and the lower limit sleeve are pseudo-tube-shaped settings, which can better fit the shape of the paper tube and reduce the damage to the paper tube caused by clamping during grinding.

[0019] As described above, a seamless paper tube grinding head device of the present invention has the following beneficial effects: by setting a grinding head frame and coordinating two groups of grinding head frames with an upper limit sleeve and a lower limit sleeve, the paper tube is edge-grinded, and the upper limit sleeve and the lower limit sleeve cooperate to press the paper tube between the upper limit sleeve and the lower limit sleeve, and the grinding device on the grinding head frame grinds the paper tube to ensure the stability of the paper tube during the grinding process. The polished paper tube moves with the lower limit sleeve under the drive of the lower limit sleeve and drops to the limit plate, and then the paper tube slides out to the receiving end with the inclination direction of the limit plate. The limit plate is close to the height of the lower limit sleeve and higher than the horizontal height of the lowest point of the lower limit sleeve. The limit plate set in this way can lift the paper tube from the lower limit sleeve when the lower limit sleeve drops to the lowest point with the paper tube processed by the grinding head, and then the polished paper tube slides off the limit plate.

[0024] The following specific embodiments illustrate the implementation of the present invention, and those familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0025] See also Figure 1 to Figure 2 The present invention provides a seamless paper tube grinding head device, comprising a frame 1, a limiting component assembled on the frame 1, and a guide component arranged between the frame 1 and the two sides of the limiting component. The limiting component comprises two groups of grinding head frames 2 symmetrically arranged on the frame 1, an upper limiting sleeve 3 is arranged between the two groups of grinding head frames 2, and a lower limiting sleeve 4 that can move up and down is arranged below the limiting sleeve. The guide component comprises limiting plates 5 arranged on both sides of the lower limiting sleeve 4, the limiting plates 5 are slidably connected to the frame 1 in the horizontal direction, the limiting plates 5 are inclined plates, and the height of the limiting plates 5 is gradually reduced in the direction away from the grinding head frame 2.

[0026] By setting a grinding head frame 2 and cooperating with an upper limit sleeve 3 and a lower limit sleeve 4 between two groups of grinding head frames 2, the paper tube is edge-grinded. The upper limit sleeve 3 and the lower limit sleeve 4 cooperate to press the paper tube between the upper limit sleeve 3 and the lower limit sleeve 4. The grinding device on the grinding head frame 2 grinds the paper tube to ensure the stability of the paper tube during the grinding process. The polished paper tube moves with the lower limit sleeve 4 under the drive of the lower limit sleeve 4 and descends to the limit plate 5. Then, the paper tube slides out to the receiving end along with the inclination direction of the limit plate 5.

[0027] A material blocking ring 6 is provided at the rear end of the limit plate 5, and the opening of the material blocking ring 6 is set in the direction away from the frame 1. The setting of the material blocking ring 6 can prevent the paper tube to be ground from sliding onto the grinding head frame 2 during the grinding process, thereby ensuring the stability of the grinding head processing. The limit plate 5 is close to the height of the lower limit sleeve 4 and higher than the horizontal height of the lowest point of the lower limit sleeve 4. The limit plate 5 is close to the height of the lower limit sleeve 4 and higher than the horizontal height of the lowest point of the lower limit sleeve 4. The limit plate 5 set in this way can lift the paper tube from the lower limit sleeve 4 when the lower limit sleeve 4 drops to the lowest point with the paper tube processed by the grinding head, and then the polished paper tube can slide off the limit plate 5.

[0028] The lower limit sleeve 4 is provided with a guide plate 7 arranged along the inclination direction of the limit plate 5. The setting of the guide plate 7 can better facilitate the paper tube after grinding to be guided out along the inclination direction of the limit plate 5. The upper limit sleeve 3 is provided with a cleaning air head 8, and the blowing direction of the cleaning air head 8 is set toward the abrasive working surface on the grinding head frame 2. By setting the cleaning air head 8 and setting the blowing direction of the cleaning air head 8 toward the abrasive working surface on the grinding head frame 2, the debris generated in the process of grinding the paper tube can be discharged to avoid accumulation on the grinding working surface and affect the subsequent paper tube grinding.

[0029] The upper limit sleeve 3 and the lower limit sleeve 4 are both quasi-tube type settings, the upper limit sleeve 3 and the lower limit sleeve 4 are relatively set, and the lower limit plate 5 is raised to the highest point and set with a gap between the upper limit plate 5. The lower limit plate 5 is raised to the highest point and set with a gap between the upper limit plate 5, which can provide sufficient supporting space for the paper tube. The upper limit sleeve 3 and the lower limit sleeve 4 are both quasi-tube type settings, which can better fit the shape of the paper tube and reduce the damage to the paper tube caused by clamping during grinding.

[0030] The present invention performs edge grinding on the paper tube by arranging a grinding head frame and cooperating with an upper limit sleeve and a lower limit sleeve between two groups of grinding head frames. The upper limit sleeve and the lower limit sleeve cooperate to press the paper tube between the upper limit sleeve and the lower limit sleeve. The grinding device on the grinding head frame performs grinding on the paper tube to ensure the stability of the paper tube during the grinding process. The polished paper tube moves with the lower limit sleeve under the drive of the lower limit sleeve and descends to the limit plate. Then, the paper tube slides out to the receiving end along with the inclination direction of the limit plate. The limit plate is close to the height of the lower limit sleeve and higher than the horizontal height of the lowest point of the lower limit sleeve. The limit plate arranged in this way can lift the paper tube from the lower limit sleeve when the lower limit sleeve carries the paper tube processed by the grinding head and descends to the lowest point, and then the polished paper tube slides off the limit plate.

[0031] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. All equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed by the present invention shall still be covered by the claims of the present invention.
