Description

Coating machine winding device

Technical Field

The utility model relates to a winding device for a coating machine, belonging to the technical field of battery production.

Background Art

In the coating process, the winding unit of the coating machine is a key equipment responsible for orderly winding the coated coiled material. However, the existing roll changing equipment of the winding unit of the coating machine has exposed many problems in actual application, which seriously affects the quality and production efficiency of the coated products.

First, at the beginning of the winding unit, the coiled material is placed in the winding tube core on the winding rack. Due to improper structural design or use of the winding tube core, the coiled material is prone to crushing, wrinkling, bulging, etc. under long-term action. These problems not only affect the appearance quality of the product, but may also cause the coiled material to break or deviate during subsequent processing.

Secondly, during the coiling process, as the coil diameter gradually increases, the coiling tension will change. Existing coiling equipment often cannot accurately control the change in tension, resulting in problems such as bulging and core deviation during the coiling process. These problems not only affect the overall quality of the product, but may also lead to instability in the coiling process, thereby affecting production efficiency.

Finally, at the end of the reeling, the existing reeling equipment usually adopts the method of changing the coil without stopping the machine, which causes the coil to rotate too much at the end during the reel changing process. Excessive rotation not only easily causes damage to the coil, but may even cause the entire roll to be scrapped, thereby increasing production costs and reducing production efficiency.

In summary, the existing roll-changing equipment of the winding unit of the coating machine has many problems in the process of coil winding, which seriously restricts the development and application of the coating process. Therefore, it is necessary to improve the roll-changing equipment of the winding unit of the coating machine to solve the above problems and improve the quality and production efficiency of the coated products.

DETAILED DESCRIPTION

The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

A coating machine winding device comprises a rotating tower body 1, a rotating tower shaft 9, two rotating towers 3 and two sets of winding mechanisms; the upper end of the rotating tower body 1 is rotatably connected to the horizontally arranged rotating tower shaft 9, and the rotating tower shaft 9 is driven to rotate by a corresponding shaft motor fixed on the rotating tower body 1. This is the prior art, so it is not repeated here. The two ends of the rotating tower shaft 9 are respectively fixedly connected to the middle part of the corresponding rotating tower 3, and the corresponding ends of the two rotating towers 3 are respectively connected to the corresponding winding mechanisms.

Each group of the winding mechanism includes a roller 2, a roller support arm 4, a winding shaft 6, a pressure roller group 7 and a cylinder 8; the two ends of the winding shaft 6 are respectively rotatably connected to the main board of the corresponding rotating tower 3, and the winding shaft 6 is driven to rotate by the corresponding winding motor fixed on the rotating tower 3. This is the prior art and will not be repeated here. The two ends of the roller 2 are respectively rotatably connected to the vertical support plate of the corresponding rotating tower 3, the cylinder body of the cylinder 8 is hinged to the rotating tower 3 through a pin, the piston rod of the cylinder 8 is hinged to the rolling support arm 4 through a pin, one end of the rolling support arm 4 is hinged to the rotating tower 3 through a pin, and the other end of the rolling support arm 4 is provided with a pressure roller group 7, and the pressure roller group 7 is arranged to fit the outer wall of the winding shaft 6.

The rotating tower shaft 9 is provided with a sensor, the sensor is connected to the controller for signal transmission, and the controller is connected to the cylinder 8 for signal transmission.

The working process of the present invention is as follows:

1. Feeding by the front mechanism: The coil 5 is smoothly transferred to the winding mechanism of the coater by the front mechanism 10 and guided by the roller 2 of the rotating tower 3.

2. Start of rewinding: The rewinding motor starts, driving the rewinding shaft 6 to start rotating and rewinding the coil. At the same time, the cylinder 8 starts to contract, driving the roller group 7 downward through the roller support arm 4, so that it lightly presses the surface of the coil 5 to ensure that the coil remains flat during the rewinding process.

3. Preparation for roll change: As the roll is being wound, when the roll needs to be changed or the roll cutting operation needs to be performed, the controller issues a command, and the rotating tower shaft 9 drives the entire rotating tower 3 to rotate 180 degrees. This action realizes the position switching between the two sets of winding mechanisms, preparing for the next roll change or roll cutting operation.

4. Air pressure regulation and roll cutting: During the roll changing or roll cutting process, the downward pressure of the air cylinder 8 is precisely adjusted through the corresponding air pressure valve to ensure that the pressure roller group 7 applies appropriate pressure to the roll material. When the roll cutting action is performed, the pressure roller group 7 presses the roll material steadily onto the other set of winding shafts 6, and then the cutting knife mechanism 14 cuts and cuts the roll material. At this time, the other set of winding mechanism starts to move, completing the automatic roll changing and winding process.

5. Real-time pressure control: As the diameter of the coiled material gradually increases, the coiling mechanism will transmit a signal to the controller in real time. The controller adjusts the pressure value of the air pressure valve according to the signal change, thereby achieving precise control of the pressure value of the pressure roller group 7 to ensure that the coiled material can remain flat during the entire winding process.

6. Cutter mechanism leaves and roller pressure is maintained: After the cutter mechanism 14 completes cutting and leaves, the pressure roller group 7 continues to maintain real-time roller pressure on the coil, and adjusts the pressure in real time by receiving the coil winding tension and length changes to ensure the flatness and stability of the coil during the coil changing process.

7. Unwinding operation: When the next coil is ready to be rolled up, the cylinder 8 extends and drives the roller group 7 to rise and leave the surface of the coil through the roller support arm 4. In this way, the coil is no longer pressed by the roller, which makes it easier for the operator to unwind and complete the entire coil changing process.
