Description

TECHNICAL FIELD

[0001] The present application relates to the field of embossing technology, in particular to an embossing reverse bending device. BACKGROUND

[0002] Aluminum foil paper refers to paper formed by bonding aluminum foil lining paper and aluminum foil paste. It is soft and easy to deform, does not transmit light, is non-polluting, and is cheap. It is widely used in high-grade cigarette, candy and other food moisture-proof and decorative packaging. After the production of aluminum foil paper, various patterns and characters need to be embossed on the aluminum foil paper to meet the decorative needs of the aluminum foil paper after packaging the product and improve the aesthetics.

[0003] At present, the embossing of aluminum foil paper is usually carried out by using embossing equipment. The produced aluminum foil paper in roll is transported to the embossing roll of the embossing equipment through the multi-roll transmission system of the embossing equipment, and then the embossed aluminum foil paper is wound, so that the embossing on the aluminum foil paper can be realized.

[0004] However, in the process of guiding and transporting the aluminum foil paper through the multiple rollers of the multi-roll transmission system, in order to ensure the traction force on the aluminum foil paper and prevent the aluminum foil paper from being torn, the aluminum foil paper needs to be bent and guided for transportation, which easily leads to the bending of the aluminum foil paper after transportation, affecting the quality and use performance of the embossed aluminum foil paper. CONTENT OF THE INVENTION

[0005] In order to improve the problem that the aluminum foil paper is bent after embossing and affects the quality and use performance, the present application provides an embossing reverse bending device.

[0006] The embossing reverse bending device provided by the present application adopts the following technical scheme:

[0007] An embossing reverse bending device, comprising a positioning seat and a reversing roller, the positioning seat is arranged on the embossing equipment, the reversing roller is rotatably arranged on the positioning seat, the reversing roller is located on the winding side of the embossing equipment, and the distance between the reversing roller and the unwinding side of the embossing equipment is less than the distance between the roller closest to the reversing roller in the transmission direction of the aluminum foil paper of the embossing equipment and the unwinding side of the embossing equipment.

[0008] By adopting the above technical scheme, the aluminum foil paper on the embossing equipment is wound onto the reversing roller. Since the distance between the reversing roller and the unwinding side of the embossing equipment is less than the distance between the roller closest to the reversing roller in the transmission direction of the aluminum foil paper of the embossing equipment and the unwinding side of the embossing equipment, the aluminum foil paper can be reversely bent and guided by the reversing roller before the winding of the embossed aluminum foil paper is completed, thereby reducing the bending of the aluminum foil paper during transportation and improving the problem that the aluminum foil paper is bent after embossing and affects the quality and use performance.

[0009] Optionally, the positioning seat is slidably mounted on the embossing device, and the positioning seat is provided with positioning bolts for positioning the positioning seat on the embossing device.

[0010] By adopting the above technical solution, the positioning seat is positioned at different heights of the embossing equipment using positioning bolts. The positioning seat drives the reversing roller to move to different positions, thereby adjusting the force of the reversing roller pressing against the aluminum foil, and thus adjusting the force that drives the aluminum foil to bend in the reverse direction, improving the applicability to the needs of driving the aluminum foil to bend in the reverse direction under different forces.

[0011] Optionally, an adjusting seat is slidably disposed on the positioning seat along the sliding direction toward the positioning seat, the reversing roller is rotatably disposed on the adjusting seat, and an adjusting screw is rotatably disposed on the positioning seat, the adjusting screw being threaded through the adjusting seat.

[0012] By adopting the above technical solution, the operator rotates the directional screw, which drives the directional seat to slide in the direction of sliding towards the positioning seat. The directional seat drives the reversing roller to move, thereby adjusting the reversing roller to different positions and adjusting the angle at which the aluminum foil is wrapped around the reversing roller, thereby adjusting the angle at which the aluminum foil is driven to bend in the opposite direction.

[0013] Optionally, a support wheel is rotatably mounted on the positioning seat, and the support wheel abuts against the reversing roller.

[0014] By adopting the above technical solution, the reversing roller of the support wheel pair is supported, thereby improving the stability of the reversing roller.

[0015] Optionally, a limiting groove is provided on the reversing roller, and the support wheel is embedded in the limiting groove.

[0016] By adopting the above technical solution, the support wheel abuts against the side wall of the limiting groove, thereby supporting the reversing roller, reducing the possibility of the reversing roller shaking, and further improving the stability of the reversing roller.

[0017] Optionally, the positioning seat is provided with a pressing seat, and the pressing seat is rotatably provided with a pressing roller for pressing the edge of the aluminum foil against the reversing roller.

[0018] By adopting the above technical solution, when aluminum foil is conveyed on the reversing roller, the edge of the aluminum foil is pressed against the reversing roller by the pressure roller, reducing the possibility of the edge of the aluminum foil curling.

[0019] Optionally, the pressure seat is slidably disposed on the positioning seat along the length direction of the reversing roller, and an adjusting screw threaded through the pressure seat is rotatably disposed on the positioning seat.

[0020] By adopting the above technical solution, the operator can rotate the adjusting screw to drive the pressure seat to slide along the length of the reversing roller. The pressure seat drives the pressure roller to move, making the pressure roller suitable for aluminum foil of different widths.

[0021] Optionally, a holding seat is slidably disposed on the pressing seat along the length direction toward the reversing roller, the pressing roller is rotatably disposed on the holding seat, and a holding screw threaded through the holding seat is rotatably disposed on the pressing seat.

[0022] By adopting the above technical solution, the operator rotates the pressing screw, causing the pressing seat to slide along the length direction towards the reversing roller. The pressing seat drives the pressure roller away from or closer to the reversing roller, which can adjust the force of the pressure roller pressing the edge of the aluminum foil on the reversing roller, and make it easier for the operator to drive the pressure roller to release the aluminum foil.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Before the aluminum foil is rewound and printed, the aluminum foil is guided to bend in the opposite direction by a reversing roller, which reduces the bending of the aluminum foil during the conveying process and improves the problem of bending of the aluminum foil after printing, which affects the quality and performance.

[0025] 2. The support rollers support the reversing rollers, improving their stability;

[0026] 3. The pressure roller presses the edge of the aluminum foil against the reversing roller, reducing the possibility of the aluminum foil edge curling. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0031] This application discloses an embossing reverse bending device.

[0032] Reference Figure 1 , Figure 2The embossing and bending device includes a positioning seat 1, a reversing roller 2, a support wheel 6, a pressing seat 7, and a pressing roller 8. The positioning seat 1 is slidably installed on the embossing equipment. A positioning bolt 3 is slidably passed through the positioning seat 1. Multiple sets of screw holes for the positioning bolt 3 to be threaded through are opened at intervals along the sliding direction of the positioning seat 1 on the embossing equipment. The operator drives the positioning seat 1 to slide on the embossing equipment, so that the positioning bolt 3 is threaded into the screw holes at different positions on the embossing equipment, thereby positioning the positioning seat 1 at different positions on the embossing equipment.

[0033] Reference Figure 1 , Figure 2 A directional seat 4 is slidably mounted on the positioning seat 1. The sliding direction of the directional seat 4 is perpendicular to the sliding direction of the positioning seat 1. A directional screw 5 is rotatably mounted on the positioning seat 1. The directional screw 5 is threaded through the directional seat 4. A reversing roller 2 is rotatably mounted on the directional seat 4. The reversing roller 2 is located on the winding side of the printing equipment. The distance between the reversing roller 2 and the unwinding side of the printing equipment is less than the distance between the roller closest to the reversing roller 2 in the aluminum foil conveying direction of the printing equipment and the unwinding side of the printing equipment.

[0034] The operator winds the aluminum foil fed on the printing equipment onto the reversing roller 2. Since the distance between the reversing roller 2 and the unwinding side of the printing equipment is less than the distance between the roller closest to the reversing roller 2 and the unwinding side of the printing equipment in the aluminum foil conveying direction, the reversing roller 2 guides the aluminum foil in the opposite direction to the direction the printing equipment is conveying. This reverses the bending and repositioning of the aluminum foil, reducing bending during conveying and improving the quality and performance issues caused by bending after printing. Furthermore, the operator can use the positioning bolts 3 to position the positioning seat 1 at different heights on the printing equipment. The positioning seat 1 carries... The movable adjusting seat 4 and the reversing roller 2 move to different height positions to adjust the force of the reversing roller 2 pressing against the aluminum foil, thereby adjusting the force that drives the aluminum foil to bend in the reverse direction. The adjusting screw 5 can also be rotated to make the adjusting seat 4 slide in a direction perpendicular to the sliding direction of the positioning seat 1. The adjusting seat 4 drives the reversing roller 2 to move to different positions in the aluminum foil conveying direction, adjusting the angle of the aluminum foil wrapped around the reversing roller 2, thereby adjusting the angle that drives the aluminum foil to bend in the reverse direction, improving the applicability to the needs of driving the aluminum foil to bend in the reverse direction under different forces and different reverse bending angles.

[0035] Reference Figure 1 , Figure 2 The support wheel 6 is rotatably mounted on the positioning seat 1. A limit groove 21 is opened on the reversing roller 2. The width of the support wheel 6 is the same as the opening width of the limit groove 21. The support wheel 6 abuts against the bottom wall of the limit groove 21. The support wheel 6 is located below the reversing roller 2.

[0036] During the rotation of the reversing roller 2, it drives the support wheel 6 to rotate. The support wheel 6 supports the reversing roller 2, and the contact between the support wheel 6 and the side wall of the limiting groove 21 can also limit the swaying of the reversing roller 2 in the length direction of the reversing roller 2, effectively improving the stability of the reversing roller 2.

[0037] Reference Figure 1 , Figure 2 The pressure seat 7 is slidably mounted on the positioning seat 1 along the length direction of the reversing roller 2. The positioning seat 1 is rotatably mounted with an adjusting screw threaded through the pressure seat 7. The pressure seat 7 is slidably mounted with a holding seat 10 along the length direction perpendicular to the reversing roller 2. The pressure seat 7 is rotatably mounted with a holding screw 11 threaded through the holding seat 10. The pressure roller 8 is rotatably mounted on the holding seat 10.

[0038] The operator rotates the adjusting screw 9, causing the pressure seat 7 to move away from the center of the reversing roller 2. Simultaneously, the operator rotates the holding screw 11, causing the holding seat 10 to move the pressure roller 8 away from the reversing roller 2. Then, aluminum foil is wound around the reversing roller 2. The operator then rotates the adjusting screw 9 again, causing the pressure seat 7 to move closer to the edge of the aluminum foil. The pressure seat 7 moves the pressure roller 8 to above the edge of the aluminum foil. Finally, the operator rotates the holding screw 11, causing the holding seat 10 to move the pressure roller 8 closer to the edge of the aluminum foil. As the reversing roller 2 moves closer to the reversing roller 2, the pressure roller 8 presses the edge of the aluminum foil against the reversing roller 2, reducing the possibility of the aluminum foil edge curling. The operator can also adjust the position of the pressure roller 8 by rotating the adjusting screw 9, so that the pressure roller 8 can be used for aluminum foil of different widths. The operator can also adjust the force of the pressure roller 8 pressing the edge of the aluminum foil against the reversing roller 2 by rotating the holding screw 11, so that the holding seat 10 moves the pressure roller 8 away from or closer to the reversing roller 2.

[0039] The implementation principle of the embossing reverse bending device in this application is as follows: The operator winds the aluminum foil paper on the embossing equipment onto the reversing roller 2, and drives the pressure roller 8 to press the edge of the aluminum foil paper against the reversing roller 2. Since the distance between the reversing roller 2 and the unwinding side of the embossing equipment is less than the distance between the roller closest to the reversing roller 2 in the conveying direction of the aluminum foil paper and the unwinding side of the embossing equipment, the aluminum foil paper can be reverse-bent before the embossing is completed. This reduces the bending of the aluminum foil paper during the conveying process and improves the problem of bending of the aluminum foil paper after embossing, which affects the quality and performance.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
