[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please refer to Figures 1 to 5. This utility model provides a spindle box for a PET winding machine, including a winding spindle 100, which is used to wind a packing tape by connecting a winding motor; it also includes a spindle box 101 and support arc plates 102. The spindle box 101 is coaxially fixed to the winding spindle 100, so that the spindle box 101 can rotate synchronously with the winding spindle 100; multiple support arc plates 102 are distributed circumferentially and slidably mounted on the spindle box 101; the multiple support arc plates 102 together form a ring concentric with the spindle box 101, which is used to support the paper tube for winding the packing tape; wherein, each support arc plate 102 can be synchronously adjusted radially along the spindle box 101 to accommodate the support of paper tubes of different diameters when installed;

[0026] When in use: When winding the packing strap, the paper tube can be inserted into the spindle box 101 first, and the inner surface of the paper tube can be pressed against it by the radial sliding adjustment of multiple support arc plates 102, thereby forming the paper tube installation and fixation on the spindle box 101; and it is also applicable to the installation and position fixation of paper tubes of different diameters.

[0027] Subsequently, by rotating the spindle box 101 driven by the winding spindle 100, the packing tape is continuously wound onto the paper tube on the spindle box 101, thereby forming a packing tape roll.

[0028] Specifically, the spindle box 101 includes an outer cylinder 1011, an inner cylinder 1012, a front cover plate 1013, and a rear cover plate 1014. The spindle box 101 is obtained by combining the four components, making the spindle box 101 detachable as a whole, which facilitates the installation or replacement of its internal components. The outer cylinder 1011 is concentrically fixed to the winding spindle 100. The inner cylinder 1012 is installed inside the outer cylinder 1011, and the two are arranged concentrically. The front cover plate 1013 is installed at the end of the outer cylinder 1011 away from the winding spindle 100. The rear cover plate 1014 is installed at the end of the outer cylinder 1011 adjacent to the winding spindle 100.

[0029] Furthermore, the diameter of the rear cover plate 1014 is larger than the diameter of the outer cylinder 1011, and the side of the rear cover plate 1014 protrudes to the outside of the support arc plate 102; that is, after the paper tube is inserted into the support arc plate 102 on the spindle box 101, the larger diameter rear cover plate 1014 can form a blockage during the installation of the paper tube, so that the paper tube can be located at a designated position on the spindle box 101.

[0030] Furthermore, the diameter of the front cover plate 1013 is not greater than the diameter of the outer cylinder 1011, and preferably the same as the diameter of the outer cylinder 1011. When the paper tube is installed on the spindle box 101, it is first inserted into the spindle box 101 from the direction adjacent to the front cover plate 1013. Since the diameter of the front cover plate 1013 is not greater than the diameter of the outer cylinder 1011, it is convenient for operators to quickly insert and install.

[0031] Furthermore, the end of the support arc plate 102 away from the winding spindle 100 is beveled and ground. When the diameter of the paper tube is equal to the diameter of the ring formed by the multiple support arc plates 102, it is difficult to insert the paper tube into the multiple support arc plates 102. Therefore, the edge of the support arc plate 102 is beveled and ground to form a slope for the paper tube insertion direction, which facilitates the insertion and installation of the paper tube.

[0032] Specifically, it also includes an adjusting component 103 for synchronously adjusting the support arc plate 102 radially along the spindle box 101; the adjusting component 103 includes a sliding plate 1031, an inclined surface 1032, a cylinder 1033, and a pressing cylinder 1034; the number of sliding plates 1031 corresponds to the number of support arc plates 102, and multiple sliding plates 1031 are equidistantly radially slidably installed between the outer cylinder 1011 and the inner cylinder 1012; one end of the sliding plate 1031 is fixedly connected to the support arc plate 102, and the other end is located inside the inner cylinder 1012 and forms an inclined surface. The surface 1032 gradually increases in slope from the direction of the extrusion cylinder 1034 to the direction of the winding spindle 100; the cylinder 1033 is fixed to the middle of the front cover plate 1013, and the output shaft faces the winding spindle 100; the extrusion cylinder 1034 is mounted on the output shaft of the cylinder 1033, and the extrusion cylinder 1034 is a conical cylinder, the surface slope of which is adapted to the slope 1032 of the slide plate 1031; wherein, the extrusion cylinder 1034 is driven by the cylinder 1033 and is extruded and engaged with the slope 1032 of the slide plate 1031;

[0033] In use: When the paper tube is installed and fitted onto the spindle box 101, the cylinder 1033 can be activated, its output shaft extends and moves toward the winding spindle 100. During the process, the output shaft will drive the extrusion cylinder 1034 to move and press against the inclined surface 1032 of the slide plate 1031. During the extrusion process, the slide plate 1031 is forced to gradually slide toward the outside of the outer cylinder 1011, that is, the slide plate 1031 drives the support arc plate 102 to slide, and then the support arc plate 102 presses against the inner surface of the paper tube, thereby fixing the position of paper tubes of different diameters.

[0034] It is worth noting that when fixing paper tubes of different diameters, it is only necessary to adjust the extension length of the output shaft of the cylinder 1033 so that the extrusion cylinder 1034 and the inclined surface 1032 at different positions of the slide plate 1031 can be pressed into contact.

[0035] Furthermore, each slide plate 1031 is provided with a receiving groove 104; a support spring 105 is installed in the receiving groove 104, one end of the support spring 105 is connected to the slide plate 1031, and the other end is connected to the inner wall of the outer cylinder 1011.

[0036] After the paper tube is wound with the packing strap, it needs to be removed along with the packing strap. At this time, simply start the cylinder 1033 to retract the output shaft, which will drive the extrusion cylinder 1034 to retract. At this time, the extrusion cylinder 1034 gradually loses its extrusion force on the slide plate 1031. Therefore, by setting the support spring 105, the slide plate 1031 / support arc plate 102, which has lost its extrusion force, can gradually return to its original position and retract under the pushing force of the support spring 105, thereby relieving the support force of the support arc plate 102 on the inner surface of the paper tube. At this time, the operator can easily remove the paper tube after the packing strap is wrapped, or install the next empty paper tube.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
