Description

Technical Field

[0001] The invention relates to the technical field of paper collection devices, and in particular to a paper collection device of a hot stamping die-cutting machine. Background Art

[0002] The hot stamping die-cutting machine is a process testing instrument used in the field of engineering and technology related to product application. It is mainly used for two process processes: hot stamping and die-cutting. The main functions of the machine include hot stamping on the surface of paper or other materials, and cutting out specific shapes or patterns through molds. The paper collection device of the hot stamping die-cutting machine is the part of the equipment that collects the paper after hot stamping and die-cutting. The paper collection device is a device used to roll up materials, papers or other flexible items.

[0003] The pneumatic shaft has important applications in the material receiving device of the die-cutting machine, especially in the process of winding paper, film or other materials. It uses the principle of air pressure to realize the automatic expansion or contraction of the paper winding shaft, so that the paper winding shaft can easily fit the inner hole of the paper roll, thereby improving the degree of automation, efficiency and ease of operation, greatly improving the level of automation, reducing manual intervention, and improving the stability of the paper roll quality.

[0004] For example, the patent with announcement number CN109879119B provides an inflatable shaft device, which realizes the simultaneous operation of multiple rolls or the operation of a single roll by setting up multiple inflatable groups with the same structure and controlling the operation of the first pin assembly in each inflatable group through multiple different air paths. However, the inflatable shaft adopts local contact and multi-point support for the support of the roll, which will cause the roll to produce certain plastic deformation, thereby reducing the contact force and causing unstable support. In addition, due to the storage environment of the roll, certain impurities will adhere to the inner wall of the roll, which will reduce the clamping force with the inflatable shaft. As the thickness of the roll increases, it is often necessary to make the expansion block protrude more outward to increase the clamping force of the inflatable shaft on the roll, but the continuous increase in the radial outward pressure will cause the deformation of the roll to increase, which is not conducive to the reuse of the roll. The existing inflatable shaft is inconvenient to take and put before and after winding, and the sliding contact friction force easily causes scratches on the inner wall of the roll, thereby affecting the contact between the roll and the inflatable shaft.

[0020] Furthermore, a paper receiving device of a hot stamping die-cutting machine also includes a frame, a feed shaft, a laminating shaft, a cutting die and a pulling shaft. The direction in which the axial direction of the inflatable shaft is located is the first direction. The support frame is fixedly arranged on the frame.

[0021] The beneficial effects of the present invention are as follows: a paper receiving device of a hot stamping die-cutting machine of the present invention, through the provided material receiving mechanism, sleeves the roll on the air expansion shaft, so that the first air channel and the second air channel suck air inwardly, and then the first sliding key sucks air inwardly through multiple first air holes, and the second sliding key sucks air inwardly through multiple second air holes, thereby absorbing impurities on the inner circumferential wall of the roll, preventing the inner circumferential wall of the roll from being stained with impurities, and the first sliding key, the second sliding key and the inner circumferential wall of the roll are not sufficiently rubbed against each other, thereby reducing the clamping force on the roll.

[0022] The airbag assembly drives the first sliding key and the second sliding key to move away from the axis of the inflatable shaft and clamp the reel. During the winding process, as the winding thickness increases, the clamping force required for the reel gradually increases. The first sliding key and the second sliding key are gradually moved away from the axis of the inflatable shaft to increase the clamping force of the first sliding key and the second sliding key on the reel. Since increasing the clamping force of the first sliding key and the second sliding key on the reel easily causes plastic deformation of the reel, the first air hole of the first sliding key and the second air hole of the second sliding key are used to inhale air inward during winding, and the negative pressure of the first air hole and the second air hole is gradually increased, providing the reel with a reverse support force that opposes the first sliding key and the second sliding key, reducing the plastic deformation of the reel and increasing the frequency of repeated use of the reel.

[0023] When the reel needs to be taken down after winding, the first sliding key is kept in contact with the reel, and the second sliding key is separated from the reel. Then the reel is supported manually or by a robot to limit the rotation of the reel and drive the air shaft to rotate. Since the first sliding key is spiral, when the first sliding key rotates and the reel does not rotate, the reel can be driven to move axially toward the air shaft, and then the reel can be unloaded smoothly without manual pushing. The operation is convenient and loading and unloading is labor-saving, thereby reducing the friction between the first sliding key, the second sliding key and the reel, and preventing the inner wall of the reel from being scratched due to friction, thereby affecting the contact between the reel and the air shaft.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Reference Figures 1 to 11 As shown, a paper receiving device of a hot stamping die-cutting machine provided in Embodiment 1 of the present invention is used to roll paper onto a reel, and includes a support frame 900 and a receiving mechanism. The receiving mechanism includes an inflatable shaft 850, a sliding key assembly, and an airbag assembly. The inflatable shaft 850 is horizontally arranged, and the inflatable shaft 850 is rotatably arranged on the support frame 900. A plurality of slide groove assemblies are provided on the inflatable shaft 850, and the plurality of slide groove assemblies are sequentially distributed along the axial direction of the inflatable shaft 850, and each slide groove assembly includes a first spiral groove 851 and a second spiral groove 853. The first spiral groove 851 and the second spiral groove 853 are sequentially distributed along the circumference of the inflatable shaft 850, and along the axial direction of the inflatable shaft 850, the first spiral groove 851 is located between two adjacent second spiral grooves 853. The spiral directions of the first spiral groove 851 and the second spiral groove 853 are opposite.

[0039] The sliding key assembly includes a plurality of first sliding keys 880 and a plurality of second sliding keys 890, each of the first sliding keys 880 is disposed in a first spiral groove 851, and each of the second sliding keys 890 is slidably disposed in a second spiral groove 853. Both the first sliding key 880 and the second sliding key 890 can move along the radial direction of the inflatable shaft 850. Both the first sliding key 880 and the second sliding key 890 are spiral-shaped, and the spiral directions of the first sliding key 880 and the second sliding key 890 are opposite. The reel is sleeved on the inflatable shaft 850, and the first sliding key 880 and the second sliding key 890 are used to abut against the inner wall of the reel. The airbag assembly is used to drive the first sliding key 880 and the second sliding key 890 to move respectively.

[0040] A first air passage 881 is provided in the first sliding key 880, and the first air passage 881 is arranged along the spiral direction of the first sliding key 880. A plurality of first air holes 882 are provided on the outer peripheral wall of the first sliding key 880, and the plurality of first air holes 882 are sequentially distributed along the extension direction of the first air passage 881, and the first air holes 882 are connected to the first air passage 881. A second air passage 891 is provided in the second sliding key 890, and the second air passage 891 is arranged along the spiral direction of the second sliding key 890. A plurality of second air holes 892 are provided on the outer peripheral wall of the second sliding key 890, and the plurality of second air holes 892 are sequentially distributed along the extension direction of the second air passage 891, and the second air holes 892 are connected to the second air passage 891.

[0041] The reel is put on the inflatable shaft 850, so that the first air channel 881 and the second air channel 891 are inwardly inhaled, and then the first sliding key 880 inwardly inhales air through the multiple first air holes 882, and the second sliding key 890 inwardly inhales air through the multiple second air holes 892, thereby absorbing impurities on the inner circumferential wall of the reel to prevent the inner circumferential wall of the reel from being stained with impurities, and the friction between the first sliding key 880, the second sliding key 890 and the inner circumferential wall of the reel is insufficient when they are against each other, thereby reducing the clamping force on the reel.

[0042] The airbag assembly drives the first sliding key 880 and the second sliding key 890 to move away from the axis of the inflatable shaft 850 and clamp the reel. In the process of winding, as the winding thickness increases, the clamping force required for the reel gradually increases. The first sliding key 880 and the second sliding key 890 gradually move away from the axis of the inflatable shaft 850 to increase the clamping force of the first sliding key 880 and the second sliding key 890 on the reel. Since increasing the clamping force of the first sliding key 880 and the second sliding key 890 on the reel easily causes plastic deformation of the reel, the first air hole 882 of the first sliding key 880 and the second air hole 892 of the second sliding key 890 are sucked inward during winding, and the negative pressure of the first air hole 882 and the second air hole 892 is gradually increased, providing the reel with a reverse support force against the first sliding key 880 and the second sliding key 890, reducing the plastic deformation of the reel and increasing the frequency of repeated use of the reel.

[0043] When the reel needs to be taken down after winding, the first sliding key 880 is kept in contact with the reel, and the second sliding key 890 is out of contact with the reel. Then, a human or mechanical hand holds the reel to limit the rotation of the reel and drive the inflatable shaft 850 to rotate. Since the first sliding key 880 is spiral, when the first sliding key 880 rotates and the reel does not rotate, it can drive the reel to move axially toward the inflatable shaft 850, and then the reel can be unloaded smoothly without manual pushing. The operation is convenient and the loading and unloading is labor-saving, thereby reducing the friction between the first sliding key 880, the second sliding key 890 and the reel, and preventing the inner wall of the reel from being scratched due to friction, thereby affecting the contact between the reel and the inflatable shaft 850.

[0044] In this embodiment, a first installation channel 854 is opened in the inflatable shaft 850 .

The motor 810 is fixedly arranged on the support frame 900, and a first gear is fixedly arranged on the output shaft of the motor 810. A second gear is fixedly arranged on the inflatable shaft 850, and the second gear and the inflatable shaft 850 are coaxially arranged. The belt connects the first gear and the second gear.

[0060] In this embodiment, a paper receiving device of a hot stamping die-cutting machine further includes a frame 100, a feed shaft 600, a laminating shaft 500, a cutting die 300 and a pulling shaft 700. The direction in which the axial direction of the air shaft 850 is located is the first direction. The support frame 900 is fixedly arranged on the frame 100. The two sides of the frame 100 along the second direction are respectively the first side and the second side, the second direction is a horizontal direction, and the second direction is perpendicular to the first direction.

[0061] The feed shaft 600, the laminating shaft 500, the heating roller 400, the cutting die 300 and the material pulling shaft 700 are all arranged on the frame 100. The feed shaft 600, the laminating shaft 500, the heating roller 400, the cutting die 300, the material pulling shaft 700 and the inflatable shaft 850 are sequentially distributed along the direction from the first side to the second side. The feed shaft 600, the laminating shaft 500 and the material pulling shaft 700 are all arranged along the first direction. The material is wound on the feed shaft 600, and the laminating shaft 500 and the material pulling shaft 700 are in contact with the material. The heating roller 400 is used to perform hot stamping on the material, and the cutting die 300 is used to perform cutting on the material.

[0062] Working process: In the initial state, the first airbag 870 and the second airbag 872 are in a contracted state, the first sliding key 880 is in the first spiral groove 851, and the second sliding key 890 is in the second spiral groove 853. The reel is put on the inflatable shaft 850, and the second air pump is started to inflate the first airbag 870 and the second airbag 872 through the third air connection pipe 871 and the fourth air connection pipe 873, so that the first airbag 870 and the second airbag 872 expand, and then push the first sliding key 880 and the second sliding key 890 to move outward, that is, the first sliding key 880 and the second sliding key 890 move in a direction away from the axis of the inflatable shaft 850.

[0063] At the same time, the first air pumps are started, one of which draws air into the third air channel 861 on the closure member 860 through the first pipeline and the first air connection pipe 8643, and draws air into the first air channel 881 in the first sliding key 880 through the first branch interface 863 and the first connecting pipe 883. The other first air pump draws air into the fourth air channel 862 on the closure member 860 through the second pipeline and the second air connection pipe 8644, and draws air into the second air channel 891 in the second sliding key 890 through the second branch interface and the second connecting pipe 893. The first sliding key 880 draws air inward through the plurality of first air holes 882, and the second sliding key 890 draws air inward through the plurality of second air holes 892, thereby absorbing impurities on the inner peripheral wall of the reel to prevent the inner peripheral wall of the reel from being stained with impurities. When the first sliding key 880, the second sliding key 890 and the inner peripheral wall of the reel are against each other, the friction is insufficient, thereby reducing the clamping force on the reel.

[0064] Until the first sliding key 880, the second sliding key 890 and the inner circumferential wall of the reel are against each other, the first sliding key 880, the second sliding key 890 clamps the reel, and because the first sliding key 880 and the second sliding key 890 are both spiral, along the axial direction of the inflatable shaft 850, the first spiral groove 851 is between two adjacent second spiral grooves 853, and multiple sliding groove components are sequentially distributed along the axial direction of the inflatable shaft 850, so that the first sliding key 880 and the second sliding key 890 are uniform in the axial direction of the reel. In addition, the projection of the first spiral block 884 on the circumference of the inflatable shaft 850 and the projection of the third spiral block 894 on the circumference of the inflatable shaft 850 form a full circle. The projection of the second spiral block 885 on the circumference of the inflatable shaft 850 and the projection of the fourth spiral block 895 on the circumference of the inflatable shaft 850 form a full circle, so that the first sliding key 880 and the second sliding key 890 are also uniform in the circumference of the reel. Therefore, the first sliding key 880 and the second sliding key 890 realize uniform support for the reel in the circumferential direction and the axial direction, thereby reducing the plastic deformation of the reel, increasing the contact force, and maintaining the stability of the support.

[0065] Finally, the material wound on the feed shaft 600 passes through the laminating shaft 500, the heating roller 400, the cutting die 300 and the pulling shaft 700 in sequence and is wound on the reel. The motor 810 is started, and the motor 810 drives the belt to rotate through the first gear, and then drives the air shaft 850 to rotate synchronously through the second gear. When the air shaft 850 rotates, it drives the reel to rotate synchronously, and the reel starts to reel the material. The cutting die 300 performs hot stamping on the material.

[0066] During the winding process, as the winding thickness increases, the clamping force required for the roll gradually increases. The second air pump gradually inflates the first airbag 870 and the second airbag 872, so that the first sliding key 880 and the second sliding key 890 gradually move away from the axis of the air shaft 850, thereby increasing the clamping force of the first sliding key 880 and the second sliding key 890 on the roll.

[0067] Since increasing the clamping force of the first slide key 880 and the second slide key 890 on the roll can easily cause plastic deformation of the roll, the first air pump is started while winding the roll to draw air inward through the first air hole 882 of the first slide key 880 and the second air hole 892 of the second slide key 890, and gradually increase the negative pressure of the first air hole 882 and the second air hole 892 to provide the roll with a reverse support force that counteracts the first air bag 870 and the second air bag 872, thereby reducing the plastic deformation of the roll and increasing the frequency of reuse of the roll.

[0068] In addition, during the winding process, since the first sliding key 880 and the second sliding key 890 are spiral, the friction between the first sliding key 880 and the second sliding key 890 and the winding drum will generate an axial force component during the rotation of the first sliding key 880 and the second sliding key 890. Since the spiral directions of the first sliding key 880 and the second sliding key 890 are opposite, the directions of the axial force components generated by the first sliding key 880 and the second sliding key 890 are opposite, thereby making the axial forces that maintain the friction force cancel each other out during the winding process, thereby maintaining the stability of the winding.

[0069] When the reel is taken down after winding, the first air pump connected to the second air bag 872 absorbs the gas in the second air bag 872, so that the second sliding key 890 moves toward the direction close to the axis of the inflatable shaft 850, and the multiple second sliding keys 890 break away from the contact with the reel.

[0070] Then, a person or a robot holds the reel to limit the rotation of the reel and drives the inflatable shaft 850 to rotate. Since the first sliding key 880 is spiral, when the first sliding key 880 rotates and the reel does not rotate, it can drive the reel to move axially toward the inflatable shaft 850, and then the reel can be smoothly unloaded without manual pushing. The operation is convenient and the loading and unloading is labor-saving, thereby reducing the friction between the first sliding key 880, the second sliding key 890 and the reel, and preventing scratches on the inner wall of the reel due to friction, thereby affecting the contact between the reel and the inflatable shaft 850.

[0071] When the reel is taken down, the first sliding key 880 and the second sliding key 890 can be moved toward the axis of the air shaft 850, so that the first sliding key 880 and the second sliding key 890 are completely separated from the reel. The first air pump is driven to blow air outward through the first air hole 882 of the first sliding key 880 and the second air hole 892 of the second sliding key 890, so that an air film is formed between the air shaft 850 and the reel, so as to reduce the friction between the air shaft 850 and the reel, thereby facilitating the removal of the reel.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
