Description

Technical Field

[0001] This utility model relates to the technical field of electronic aluminum foil processing, and in particular to a rewinding machine for electronic aluminum foil processing. Background Technology

[0002] In the production process of electronic aluminum foil, the rewinding process plays a crucial role. As the final step, it is responsible for rewinding or trimming the finished aluminum foil. This process not only adjusts the shape of the finished aluminum foil but is also a key step for meticulous quality inspection. Through rewinding, quality defects in the finished aluminum foil can be detected and corrected in a timely manner, thereby ensuring that the final product meets high quality standards. The stable operation of the rewinding machine is crucial for ensuring the quality of the finished product and the safety of personnel around the equipment. In actual production, the rewinding machine motor gearbox shaft and the reel are connected by a coupling. Due to structural design deficiencies, separation often occurs. This problem leads to serious quality defects such as layering, surface scratches, and tape breakage in the running coil, which not only affects the final product quality but may also lead to a series of negative consequences such as customer complaints, product downgrading, and even scrapping. More seriously, the separation of the coupling also poses a potential personal safety risk and threatens the safety and stability of the production environment.

[0003] Traditional rewinding machine shaft couplings use flat jaws at both ends, lacking a necessary closed-loop control (limit control) mechanism. During normal operation, slight vibrations of the shaft can cause the flat jaws at both ends of the coupling to gradually loosen and eventually disengage, leading to abnormal equipment operation. Attempts to solve this problem have been made to grind the edges of the jaws, adjust the cylinder pressure to increase the clamping force, and even replace the jaws with completely new ones. Unfortunately, these measures have failed to effectively resolve the coupling disengagement issue.

[0004] The above background information is provided only to aid in understanding the concept and technical solution of this utility model. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application. Utility Model Content

[0005] The purpose of this invention is to propose a rewinding machine for electronic aluminum foil processing, so as to solve the technical problem of frequent disengagement of the coupling between the motor reducer shaft and the air expansion shaft in the existing technology.

[0006] Therefore, this utility model proposes a rewinding machine for electronic aluminum foil processing.

[0007] Preferably, the present invention may also have the following technical features:

[0008] A rewinding machine for processing electronic aluminum foil includes a motor gearbox, a gearbox shaft, a first coupling, a second coupling, an air shaft, a locking block, a cylinder, and a control system. The gearbox shaft is coaxial with the first coupling, the second coupling, and the air shaft.

[0009] The first coupling is located at the right end of the gearbox shaft, and the second coupling is located at the left end of the air expansion shaft. The first coupling and the second coupling cooperate to connect the gearbox shaft and the air expansion shaft together. The motor gearbox drives the gearbox shaft to rotate, so that the air expansion shaft rotates together with the gearbox shaft to roll up the electronic aluminum foil.

[0010] The locking block is connected to the left end of the first coupling via a bearing;

[0011] The cylinder is connected to the lower end of the locking block via a connecting rod. The piston rod of the cylinder extends to the right. A magnetic switch is installed at a certain position on the cylinder. When the magnetic switch senses that the piston rod of the cylinder has moved to a certain position, it can trigger the control system to adjust the working state of the cylinder, so that the cylinder drives the locking block and the first coupling together to push towards the second coupling via the connecting rod, thereby achieving the locking effect.

[0012] Preferably, the side of the first coupling is stepped, and the locking block is located at the point where the diameter of the first coupling is the smallest.

[0013] Preferably, a groove is provided on the left end face of the rightmost step of the first coupling and the right end face of the second coupling, and a pin is provided in the groove. Corresponding to the position of the pin, pin holes are provided in the first coupling and the second coupling, as well as on the gearbox shaft and the air expansion shaft, so that the pin can abut against the gearbox shaft and the air expansion shaft.

[0014] Preferably, the meshing surfaces of the first coupling and the second coupling are inclined planes with the same angle, wherein the angle of the inclined plane is 0° to 30°.

[0015] Preferably, the angle of the inclined plane is 8°.

[0016] Preferably, the first coupling and the second coupling are made of wear-resistant metal materials.

[0017] Preferably, the first coupling and the second coupling are made of one or more materials selected from 40Cr, 42CrMo and 40CrNiMo.

[0018] Preferably, the two ends of the air shaft are air shaft heads, the diameter of the air shaft head is smaller than the diameter of the middle part of the air shaft, and a bearing seat is provided at the air shaft head to place the air shaft on the table of the rewinding machine.

[0019] The beneficial effects of this utility model compared with the prior art include:

[0020] 1. This utility model connects a cylinder to the lower end of a locking block via a connecting rod, causing the piston rod of the cylinder to extend to the right. A magnetic switch is installed at a certain position on the cylinder. When the rewinding machine is working, due to slight vibrations, the locking block will move to the left along with the first coupling. Due to the action of the connecting rod, the piston rod of the cylinder will simultaneously disengage to the right by the same distance. When the piston rod of the cylinder disengages a certain distance, the magnetic switch senses this and triggers the control system to adjust the working state of the cylinder. This allows the cylinder to push the locking block and the first coupling together towards the second coupling via the connecting rod, preventing them from disengaging from the second coupling. This improves the stability of the equipment operation. Through the automated control of the system, manual intervention during coupling disengagement is reduced, lowering personal safety risks, improving production efficiency, and enhancing product quality.

[0021] 2. In this utility model, the side of the first coupling is set in a stepped shape, and the bearing is located at the smallest diameter of the first coupling. That is to say, the right side of the bearing has a larger diameter, which makes the locking block lock the coupling more effectively.

[0022] 3. This utility model provides grooves on the left end face of the rightmost step of the first coupling and the right end face of the second coupling, and provides pins in the grooves so that the pins abut against the gearbox shaft and the air expansion shaft. This structure can prevent shaft movement to a certain extent, thereby preventing the coupling from coming off.

[0023] 4. The meshing surfaces of the first coupling and the second coupling of this utility model are inclined planes with the same angle. The couplings are connected by inclined planes, so that the force on the end face is not in the direction of the central axis of the coupling, which can prevent the first coupling from sliding out to a certain extent.

[0024] 5. The first and second couplings of this utility model are made of wear-resistant metal materials, which can reduce the wear of the couplings and reduce the impact of iron powder falling off during wear on the quality of electronic aluminum foil products. Attached Figure Description

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to specific embodiments and the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0029] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein the same reference numerals denote the same parts unless otherwise specifically stated.

[0030] A rewinding machine for electronic aluminum foil processing, such as Figure 1As shown, the system includes a motor gearbox 1, a gearbox shaft 2, a first coupling 3, a second coupling 4, an air shaft 5, a locking block 6, a cylinder 7, and a control system. Specifically, these components can be mounted on the table 12 of the rewinding machine via a bracket 14, ensuring that the gearbox shaft 2 is coaxial with the first coupling 3, the second coupling 4, and the air shaft 5. The first coupling 3 is located at the right end of the gearbox shaft 2, and the second coupling 4 is located at the left end of the air shaft 5. The first coupling 3 and the second coupling 4 work together to connect the gearbox shaft 2 and the air shaft 5. The motor gearbox 1 drives the gearbox shaft 2 to rotate, causing the air shaft 5 to rotate along with the gearbox shaft 2, thereby winding up the electronic aluminum foil. Specifically, the electronic aluminum foil is wound around the air shaft 5. The locking block 6 is located between the motor gearbox 1 and the first coupling 3. Specifically, the locking block 6 is connected to the left end of the first coupling 3 via a bearing 8. The cylinder 7 is connected to the lower end of the locking block 6 via a connecting rod 13. In actual production, the middle part of the connecting rod 13 can be movably connected to the bracket 14, so that the connecting rod 13 can rotate with the connection point. The cylinder piston rod 701 pushes out in the right direction. When the rewinding machine is working, due to slight vibration, the locking block 6 will move to the left along with the first coupling 3. Due to the action of the connecting rod 13 (it can be understood that the connecting rod 13 should have a certain rigidity), the cylinder piston rod 701 will simultaneously move out to the right by the same distance. A magnetic switch 10 is set at a certain position on the cylinder 7. When the magnetic switch 10 senses that the cylinder piston rod 701 has moved to a certain position, it can trigger the control system to adjust the working state of the cylinder 7, so that the cylinder 7 pushes the locking block 6 and the first coupling 3 together towards the second coupling 4 through the connecting rod to achieve the locking effect and prevent it from disengaging from the second coupling 4. Understandably, in this embodiment, under normal operating conditions of the rewinder, the cylinder piston rod 701 extends by a certain amount L. In some examples, the magnetic switch 10 can be set at the position where the cylinder piston rod 701 extends by L+1cm. That is, when the cylinder piston rod 701 extends by 1cm more than normal, the magnetic switch 10 will sense it and trigger the control system to adjust the working state of the cylinder 7. The adjustment of the working state of the cylinder 7 can specifically be to supplement the air volume of the cylinder 7 or to increase the air pressure of the cylinder 7.

[0031] Preferably, the first coupling 3 and the second coupling 4 are made of wear-resistant metal materials, specifically one or more of 40Cr, 42CrMo and 40CrNiMo. This not only reduces the wear of the coupling, but also reduces the impact of iron powder falling off during wear on the quality of electronic aluminum foil products. The falling iron powder may cause scratches on the surface of the electronic aluminum foil, or even scratch the electronic aluminum foil and cause it to break, resulting in material waste, affecting production efficiency and increasing production costs.

[0032] In some examples of this embodiment, the side of the first coupling 3 is stepped, and the locking block 6 is located at the point where the diameter of the first coupling 3 is smallest, such as... Figure 1 As shown, the diameter of the first coupling 3 increases from left to right. As can be seen from the figure, the bearing 8 is located inside the locking block 6, and the right end of the bearing 8 is exactly abutting the step of the first coupling 3, which makes the locking block 6 lock the first coupling 3 more effectively.

[0033] In some examples of this embodiment, such as Figure 1 and 2 As shown, a groove 301 is provided on the left end face of the rightmost step of the first coupling 3 and the right end face of the second coupling 4. A pin 9 is provided in the groove 301. Corresponding to the position of the pin 9, pin holes are provided in the first coupling 3 and the second coupling 4, as well as on the gearbox shaft 2 and the air expansion shaft 5, so that the pin 9 can abut against the gearbox shaft 2 and the air expansion shaft 5. Specifically, a spring 15 can be provided on the pin 9. When locking is required, the spring 15 is compressed downwards, and then the pin 9 is locked into the locking position 302. This structure can prevent the gearbox shaft 2 and the air expansion shaft 5 from moving to a certain extent, thereby preventing the first coupling 3 from coming off.

[0034] In other examples of this embodiment, the meshing surfaces of the first coupling 3 and the second coupling 4 are inclined planes with the same angle. The angle can be set to 0° to 30°, preferably 8°, so that the first coupling 3 and the second coupling 4 are inclined planes meshing together. When the equipment is working, the force generated by the collision of the first coupling 3 and the second coupling 4 is not in the direction of its central axis. This can reduce the force distributed in the direction of the central axis to a certain extent, and thus prevent the first coupling 3 from slipping out to a certain extent.

[0035] In actual production, the two ends of the air shaft 5 are air shaft heads 501. The diameter of the air shaft head 501 is smaller than the diameter of the middle part of the air shaft 5. A bearing seat 11 is provided at the air shaft head 501 to set the air shaft 5 on the table 12 of the rewinding machine. This structure enables the rewinding machine to roll up electronic aluminum foil better.

[0036] The working principle of the rewinding machine used for electronic aluminum foil processing is as follows: Place the air shaft 5 in the working position, install the first coupling 3 and the second coupling 4, adjust the extension distance of the cylinder piston rod 701, and drive the locking block 6 to the right through the connecting rod 13, so that the first coupling 3 and the second coupling 4 are engaged and locked. Insert and lock the pins 9 on the first coupling 3 and the second coupling 4. During the production process, when the magnetic switch 10 on the cylinder 7 senses that the cylinder piston rod 701 has moved forward by 1cm, the equipment will sound an alarm. The control system will adjust the working state of the cylinder 7, so that the connecting rod 13 drives the locking block 6 to move to the right, thereby locking the first coupling 3 and preventing it from disengaging from the second coupling 4.

[0037] Those skilled in the art will recognize that numerous variations are possible with respect to the above description, and the embodiments and figures are merely for describing one or more specific implementations.

[0038] Although exemplary embodiments of the present invention have been described and illustrated, those skilled in the art will understand that various changes and substitutions can be made thereto without departing from the spirit of the present invention. Furthermore, many modifications can be made to adapt specific situations to the doctrine of the present invention without departing from the central concept of the present invention described herein. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but may include all embodiments and equivalents that fall within the scope of the present invention.
