Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping paper roll cutting, in particular to a hot stamping paper roll cutting machine and a supporting cylinder assembly for the paper roll. Background Art

[0002] The hot stamping paper rolls in the prior art generally involve different paper rolls according to actual production needs, and are conventionally classified according to the inner diameter of the paper rolls, such as 30cm inner diameter, 70cm inner diameter, and other different specifications of paper rolls. In actual use, according to the hot stamping production process requirements, the paper roll needs to be cut into several parts along the axial direction.

[0003] The existing cutting form is that a main shaft with a rotating shaft and a coaxial sleeve with the rotating shaft is rotated on the frame of the cutting machine, and the main shaft is used to sleeve the hot stamping paper roll. The outer end of the rotating shaft is connected to a driving mechanism. At the same time, a locking member that cooperates with the main shaft to limit rotation is also provided on the frame, such as Figure 1 As shown, the axis of the main shaft 2 is consistent with the rotating shaft 1 and extends in the horizontal direction. At the same time, an extrusion long hole is provided along the radial direction of the rotating shaft 1. A push rod 3 is coaxially inserted inward at one end of the main shaft, and the inner end of the push rod 3 extends into the extrusion long hole. A push cylinder is arranged at the rear end of the push rod, and a support block 4 is inserted and guided in the extrusion long hole. Before cutting, the paper roll is inserted into the main shaft, and one end of the paper roll is sleeved at the position of the support block. The main shaft is locked by the locking piece, and then the push cylinder pushes the push rod inward to squeeze the support block radially outward to support the paper roll through the support block. When the driving mechanism drives the rotating shaft to rotate, the support block drives the paper roll to rotate synchronously around the main shaft. By adjusting the position of the cutter on the paper roll and pressing down the cutter, the paper roll is pressed and cut during the rotation process. After that, the cut paper roll is separated from the main body and continues to rotate, and the uncut paper roll is separated from the support block to complete the cutting.

[0004] However, in the prior art, when paper rolls of different sizes are classified and cut, due to the differences in the inner diameters of the paper rolls and the relatively fixed size of the spindle, it is necessary to purchase cutting machines with different types of spindle sizes to meet the cutting requirements of multiple types of paper rolls, which leads to a significant increase in the overall processing cost, adding unnecessary costs to the enterprise. At the same time, it occupies a large area of ​​the factory, affecting the installation and layout of other equipment. Utility Model Content

[0032] In order to make the technical purpose, technical solution and beneficial effects of the present utility model clearer, the technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] The specific embodiment of the hot stamping paper roll cutting machine involved in the utility model is as follows Figures 2 to 6 As shown, the cutting machine includes a frame (not shown in the figure), on which a rotating shaft 1 and a main shaft 2 coaxially inserted with the rotating shaft 1 are rotatably mounted, and the main shaft 2 is used to sleeve a small-caliber hot stamping paper roll 7. The outer end of the rotating shaft 1 is connected to a driving mechanism, and a locking member that cooperates with the main shaft 2 to limit rotation is also provided on the frame. The rotating shaft 1 is driven by the driving mechanism to rotate, and the main shaft 2 is relatively locked due to the locking of the main shaft 2 by the locking member. The paper roll sleeved on the main shaft 2 and the rotating shaft 1 is relatively locked by the support block 4 on the rotating shaft 1, meeting the rotation requirement of the paper roll during cutting.

[0034] The cutting machine further comprises a support cylinder assembly, which comprises a support cylinder 5, which is used to be rotatably sleeved on the main shaft 2 of the cutting machine, and whose axial dimension is smaller than the axial dimension of the main shaft 2. The support cylinder 5 is used to sleeve a large-caliber hot stamping paper roll 7. Thus, by switching the support cylinder 5, the hot stamping paper rolls 7 of different calibers can be replaced and cut.

[0035] The axis of the support cylinder 5 is defined to extend in the left-right direction, and the left end of the support cylinder 5 is rotatably assembled with a base sleeve 6. In this embodiment, the base sleeve 6 includes an inner sleeve 61 and an outer sleeve 62 which are mutually sleeved with each other. The inner sleeve 61 is rotatably assembled with the support cylinder 5, and a stop structure is provided between the inner sleeve 61 and the outer sleeve 62. Specifically, a step hole 51 extending to the right is provided at the left end of the support cylinder 5, and a bearing 8 is stoppered and limited at the step hole 51, and the bearing 8 is axially limited by a hole end retaining ring 9. The inner sleeve 61 is strongly mounted on the inner ring of the bearing 8, thereby realizing the relative rotation assembly of the inner sleeve 61 and the support cylinder 5. The stop structure includes a locking screw 64 which is integrally inserted between the inner sleeve 61 and the outer sleeve 62 and extends obliquely. The inner diameter of the inner sleeve 61 is consistent with the outer diameter of the main shaft 2, so that the support cylinder 5 can rotate relatively smoothly on the main shaft 2.

[0036] The base sleeve 6 has a left locking part for rotating on the rotating shaft 1 of the cutting machine. The left locking part has a left locking structure for limiting the relative rotation of the base sleeve 6 and the rotating shaft 1. Specifically, the left end of the base sleeve 6 has a left locking sleeve. The left locking structure includes a left locking hole that is radially penetrated and arranged on the left locking sleeve, and also includes a left tightening pin 63 screwed into the left locking hole. Furthermore, the inner sleeve 61 of the base sleeve 6 protrudes to the left and extends from the outer sleeve 62, and the protruding part constitutes the left locking sleeve. In order to ensure that the inner sleeve 61 is smoothly inserted on the rotating shaft 1, the support block 4 on the rotating shaft 1 needs to be removed before inserting.

[0037] The right end of the support cylinder 5 has a right locking portion, and the right locking portion has a right locking structure for limiting the relative rotation locking of the support cylinder 5 and the main shaft 2; the right end of the support cylinder 5 is connected with a right locking sleeve 52, and the right locking structure includes a right locking hole arranged on the right locking sleeve 52 in a radial direction, and also includes a right fixing nail 53 screwed into the right locking hole. Specifically, the right locking sleeve 52 is welded and fixed on the right end of the support cylinder 5, and the inner diameter of the right locking sleeve 52 is consistent with the outer diameter of the main shaft 2, and the right locking sleeve 52 and the support cylinder 5 are relatively fixed by welding, or other fixing parts are used to achieve relative rotation fixing.

[0038] After the large-diameter hot stamping paper roll 7 is sleeved on the outside of the base sleeve 6 and the support tube 5, in order to achieve relative anti-rotation locking of the hot stamping paper roll 7 and the base sleeve 6, a positioning sleeve 65 is sleeved on the outer side of the base sleeve 6 for positioning the paper roll. In this embodiment, the positioning sleeve 65 is sleeved on the outer sleeve 62, the thickness of the positioning sleeve 65 is relatively small, and there are stoppers on the left and right ends of the base sleeve 6 for cooperating with the positioning limit anti-detachment. The outer wall of the base sleeve 6 is provided with a concave surface 621 which is gradually inclined radially inwardly along the rotation direction of the base sleeve 6. The setting of the concave surface 621 forms a cam structure on at least a portion of the outer peripheral surface of the base sleeve 6, and at the same time A top block 66 is mounted on the outer wall of the base sleeve 6 so as to slide along the inclined direction of the concave surface 621. During the sliding process of the top block 66 along the concave surface 621, its center distance relative to the base sleeve 6 gradually increases, so that the top block 66 moves radially relative to the positioning sleeve 65. The positioning sleeve 65 is provided with a guide hole 651 for guiding the top block 66 to extend outward. When the base sleeve 6 rotates relative to the positioning sleeve 65, the top block 66 can be driven to slide on the concave surface 621 along the extension direction facing away from the concave surface 621, and during the sliding process, the outer end of the top block 66 is pushed outward from the positioning sleeve 65 to prop up the paper roll.

[0039] In order to ensure stable support for the paper roll, the outer end surface of the top block 66 is an arc surface, and anti-slip grooves 661 are provided on the arc surface.

[0040] Preferably, after the paper roll is propped up, in order to ensure the coaxiality between the hot stamping paper roll 7 and the base sleeve 6 , the outer side wall of the base sleeve 6 has more than two convex surfaces, and the convex surfaces are arranged symmetrically around the central axis of the base sleeve 6 .

[0041] As a preferred embodiment, in order to ensure the positioning and assembly of the hot stamping paper roll 7, an elastic pin 67 is fixed to the base sleeve 6. The elastic pin 67 extends radially, and the outer end of the elastic pin 67 passes through the positioning sleeve 65 and elastically abuts against the inner wall of the roll.

[0042] In this embodiment, in order to prevent the cutter from damaging the outer surface of the support tube 5 during cutting, a protective sleeve 10 made of plastic is provided on the outer side of the support tube 5. The outer diameter of the protective sleeve 10 is consistent with the outer diameter of the positioning sleeve 65, and both are consistent with the inner diameter of the large-diameter hot stamping paper roll 7.

[0043] As a preferred embodiment, the outer diameter of the main shaft 2 is 30 mm, and the outer diameter of the protective sleeve 10 is 70 mm, so as to adapt to two specifications of hot stamping paper rolls 7. Of course, in other embodiments, for hot stamping paper rolls 7 with more calibers, more than two support cylinder assemblies can be provided, and one set is provided on the main shaft 2 and the rotating shaft 1 of the frame, and the inner diameters of the support cylinders 5 are consistent, wherein the outer diameter of at least one of the two support cylinder assemblies is greater than the outer diameter of the other, that is, the outer diameters of each two support cylinders 5 are inconsistent, so as to meet the cutting requirements of hot stamping paper rolls 7 with different calibers.

[0044] The structure of the embodiment of the support cylinder assembly involved in the present utility model is consistent with the structure of the support cylinder assembly in the above-mentioned embodiment of the cutting machine, and will not be described in detail.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention shall be included in the scope of protection of the claims of the present invention.
