Description

Technical Field

[0001] This utility model belongs to the field of gold foil processing and cutting technology, and specifically relates to a gold foil processing and cutting device. Background Technology

[0002] Gold leaf processing and cutting equipment is a mechanical device specifically designed for cutting gold leaf. Gold leaf, a precious material with unique physical properties, is widely used in industries such as handicrafts, decoration, and electronics. The cutting process is crucial in gold leaf production, as it precisely divides large areas of gold leaf into the required sizes and shapes to meet the manufacturing requirements of different products. Traditional gold leaf processing and cutting equipment typically consists of an unwinding mechanism, a cutting mechanism, and a rewinding mechanism. Through the coordinated work of these mechanisms, continuous cutting and conveying of gold leaf is achieved. However, with the development of the gold leaf processing industry and the increasing demands for production efficiency and product quality, existing gold leaf processing and cutting equipment has gradually revealed some problems in practical use.

[0003] In traditional gold foil processing and cutting equipment, the installation method of the unwinding roller is often relatively fixed, which brings many inconveniences to the unwinding operation of gold foil. When it is necessary to change to gold foil rolls of different specifications, the process of disassembling and installing the unwinding roller is cumbersome and time-consuming, which not only reduces production efficiency, but may also lead to damage to the unwinding roller or waste of gold foil rolls due to improper operation. In addition, the structure of the cutting mechanism is relatively simple, and the cutting width is usually fixed, which cannot be flexibly adjusted to meet the cutting needs of gold foil of different widths. This means that when facing diverse product orders, the equipment needs to frequently replace the entire cutting mechanism or readjust other related parts of the equipment, which increases the maintenance cost and operational complexity of the equipment, making it difficult to meet the requirements of modern gold foil processing enterprises for efficient and flexible production.

[0012] 1. This utility model, by setting up an unwinding roller disassembly and assembly mechanism, realizes the quick disassembly and assembly of the unwinding roller. With the help of the adjustment component to rotate the bidirectional screw, the nut block drives the support plate to move, easily releasing or fixing the unwinding roller body, which greatly improves the efficiency of changing the unwinding roller, reduces the time wasted due to changing the unwinding roller, and reduces the risk of equipment damage.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1-4The present invention provides the following technical solution: a gold foil processing and cutting device, including a base plate 1, a support foot 8 at the lower corner of the base plate 1, a conveyor belt 7 on one side of the upper end of the base plate 1, a mounting frame 10 at the center of the upper end of the base plate 1, a limit roller 9 on the lower side of the mounting frame 10, a waste collection roller 5 on the upper side of the mounting frame 10, a mounting plate 3 on the upper end of the base plate 1 near the mounting frame 10, a guide roller 4 on the upper side of the mounting plate 3, a roll unwinding and disassembling mechanism 2 on the upper end of the base plate 1 near the mounting plate 3, and a cutting shear spacing adjustment mechanism 6 on the other side of the upper end of the base plate 1 near the mounting frame 10.

[0022] Specifically, the unwinding roller assembly / disassembly mechanism 2 includes an unwinding roller body 22, a limiting plate 24, a rotating shaft 25, a support plate 26, a nut block 27, a bidirectional lead screw 28, and an adjusting assembly 29. The bidirectional lead screw 28 is rotatably connected to the upper side of the base plate 1. The other end of the bidirectional lead screw 28 is equipped with the adjusting assembly 29. Two sets of nut blocks 27 are symmetrically arranged on the surface of the bidirectional lead screw 28. The upper end of the nut block 27 is equipped with the support plate 26. The side of the support plate 26 is rotatably connected to the rotating shaft 25. The other end of the rotating shaft 25 is equipped with the limiting plate 24. The side of the limiting plate 24 is equipped with the unwinding roller body 22.

[0023] By adopting the above technical solution, the unwinding roller can be quickly disassembled and assembled. When the unwinding roller body 22 needs to be replaced, simply rotate the bidirectional screw 28 by adjusting the component 29 to move the two sets of nut blocks 27 relative to each other, thereby driving the support plate 26 to move to both sides and releasing the unwinding roller body 22, which can then be easily disassembled. When installing a new unwinding roller body 22, the operation process is reversed, which greatly improves the efficiency of replacing the unwinding roller, reduces the time wasted due to replacing the unwinding roller, and also reduces the risk of equipment damage caused by frequent disassembly and assembly.

[0024] Specifically, the unwinding roller assembly / disassembly mechanism 2 also includes a hexagonal slot 21 and a hexagonal insert 23. The side of the limiting plate 24 is provided with a hexagonal insert 23, and the side of the unwinding roller body 22 is provided with a hexagonal slot 21 corresponding to the hexagonal insert 23.

[0025] By adopting the above technical solution, the connection stability between the unwinding roller body 22 and the limiting plate 24 is further enhanced. The cooperation between the hexagonal insert 23 and the hexagonal slot 21 enables the unwinding roller body 22 to maintain more stable synchronization with the limiting plate 24 during rotation, avoiding the problem of uneven gold foil unwinding caused by the shaking or loosening of the unwinding roller body 22, improving the quality and stability of gold foil unwinding, and thus ensuring the smooth progress of subsequent cutting processes.

[0026] Specifically, the adjustment assembly 29 includes a limiting groove 291, an adjustment knob 292, a limiting block 293, a limiting plate 294, a square groove 295, a spring 296, and a center rod 297. The other end of the bidirectional lead screw 28 has a square groove 295 inside. The limiting plate 294 is slidably connected inside the square groove 295. The center rod 297 is located on the side of the limiting plate 294. The spring 296 is fitted inside the square groove 295 on the surface of the center rod 297. The other end of the center rod 297 has an adjustment knob 292. The other end of the bidirectional lead screw 28 has a limiting block 293 on its side. The inner wall of the adjustment knob 292 has a limiting groove 291 corresponding to the limiting block 293.

[0027] By adopting the above technical solution, when the adjustment knob 292 is rotated, it will drive the bidirectional lead screw 28 to rotate. After the adjustment knob 292 has rotated the bidirectional lead screw 28, the spring 296 will drive the limiting block 293 to abut against the end of the square groove 295, and drive the adjustment knob 292 to contact the base plate 1. The setting of the limiting block 293 and the limiting groove 291 can avoid the problem of misalignment between the adjustment knob 292 and the bidirectional lead screw 28.

[0028] In this embodiment, the gold foil roll is first installed on the unwinding roller body 22. By rotating the adjustment knob 292, the bidirectional lead screw 28 rotates, driving the nut block 27 to move, thereby causing the support plate 26 to move closer to the center, fixing the unwinding roller body 22 between the limiting plates 24. Then, the equipment is started, and the gold foil is released from the unwinding roller body 22. Guided by the guide roller 4 and the limiting roller 9, it enters the cutting shear spacing adjustment mechanism 6 for cutting. The cut gold foil waste is collected by the waste collection roller 5, while the cut gold foil is transported to the next process by the conveyor belt 7. Throughout the process, the quick disassembly and assembly function and stable connection performance of the unwinding roller assembly and disassembly mechanism 2 ensure the smooth and efficient unwinding of the gold foil, providing a good foundation for the subsequent cutting process.

[0029] Example 2

[0030] The difference between this embodiment and Embodiment 1 is that the cutting shear spacing adjustment mechanism 6 includes an adjustment plate 61, a second nut block 62, a second bidirectional lead screw 64, a first motor 65, a second motor 66, cutting shears 67, and a fixing frame 68. The fixing frame 68 is located at the upper end of the base plate 1 near the conveyor belt 7. A first motor 65 is located on the upper side of the fixing frame 68. A second bidirectional lead screw 64 is located at the output end of the first motor 65. Two sets of second nut blocks 62 are symmetrically arranged on the surface of the second bidirectional lead screw 64. The adjustment plate 61 is located at the lower end of the second nut block 62. A second motor 66 is located on the lower side of the adjustment plate 61. The cutting shears 67 are located at the output end of the second motor 66.

[0031] By adopting the above technical solution, the spacing between the cutting shears 67 can be flexibly adjusted. The motor 65 drives the bidirectional lead screw 64 to rotate, causing the two sets of nut blocks 62 to move relative to each other, thereby driving the adjusting plate 61 to move and thus changing the spacing between the cutting shears 67. This adjustment method can be quickly adjusted according to the cutting requirements of gold foil of different widths without replacing the entire cutting mechanism or readjusting other parts of the equipment, which greatly improves the adaptability and production efficiency of the equipment and reduces the maintenance cost and operation complexity of the equipment.

[0032] Specifically, a sliding rod 63 is provided through the interior of the other side of the nut block 62 and is slidably connected to it through a through hole.

[0033] By adopting the above technical solution, the stability and accuracy of the movement of nut block 2 62 are further improved. The setting of slide bar 63 restricts the movement direction of nut block 2 62, so that it can only move along the axial direction of slide bar 63, avoiding the offset or shaking of nut block 2 62 during movement, thereby ensuring the accuracy of the spacing adjustment of cutting shears 67 and improving the quality and accuracy of gold foil cutting.

[0034] In this embodiment, according to the required gold foil width, motor 65 is started, driving the bidirectional lead screw 64 to rotate, thereby adjusting the position of nut block 62 and changing the spacing between the cutting blades 67. Once the spacing of the cutting blades 67 is adjusted to the appropriate position, motor 66 is started, causing the cutting blades 67 to begin cutting the gold foil. The cut gold foil waste is collected by waste collection roller 5, and the cut gold foil is conveyed to the next process via conveyor belt 7. Throughout the cutting process, the flexible adjustment function and high-precision cutting performance of the cutting blade spacing adjustment mechanism 6 ensure the accuracy and consistency of gold foil cutting, meeting the requirements of different product orders for gold foil cutting width, and improving the company's production efficiency and product quality.

[0035] The working principle and usage process of this utility model are as follows: First, the gold foil roll is installed on the unwinding roller body 22. By rotating the adjusting knob 292, the bidirectional lead screw 28 rotates, driving the nut block 27 to move, thereby causing the support plate 26 to move towards the center, fixing the unwinding roller body 22 between the limiting plates 24. Then, the equipment is started, and the gold foil is released from the unwinding roller body 22. Guided by the guide roller 4 and the limiting roller 9, it enters the cutting shear spacing adjustment mechanism 6 for cutting. The cut gold foil waste is collected by the waste collection roller 5, while the cut gold foil is conveyed to the next process via the conveyor belt 7. During the process, the quick assembly and disassembly function and stable connection performance of the unwinding roller assembly / disassembly mechanism 2 ensured the smooth and efficient unwinding of the gold foil, providing a good foundation for the subsequent cutting process. Based on the required gold foil width, motor 65 was started, driving the bidirectional lead screw 64 to rotate, thereby adjusting the position of the nut block 62 and changing the spacing between the cutting shears 67. Once the spacing of the cutting shears 67 was adjusted to the appropriate position, motor 66 was started, causing the cutting shears 67 to begin cutting the gold foil. The cut gold foil waste was collected by the waste collection roller 5, and the cut gold foil was conveyed to the next process via the conveyor belt 7. Throughout the cutting process, the flexible adjustment function and high-precision cutting performance of the cutting shear spacing adjustment mechanism 6 ensured the accuracy and consistency of the gold foil cutting, meeting the requirements of different product orders for gold foil cutting width, and improving the company's production efficiency and product quality.
