Description

Technical Field

[0001] The utility model relates to the field of coating technology die heads, in particular to a lip-sealing device for automatically sealing slurry circulation in a die head of a coating machine. Background Art

[0002] When die coating is used in lithium battery spraying, due to the large size and complex functions of the coating machine, the main machine often needs to be stopped for inspection and adjustment (for example, the foil breaks and needs to be rethreaded, etc.), and coating cannot be carried out at this time. In order to prevent the slurry in the coating die from stopping to flow, so as to prevent the slurry from settling in the die and affecting the coating quality during coating, the feeding unit of the coating machine is always in operation. In order to prevent the slurry in the die from circulating when the main machine stops for inspection and no coating is carried out, the existing practice is to place a layer of foam between the coating die and the coating steel roller, and press the coating die against the coating steel roller (the position during coating), so that the lip of the coating die squeezes the foam onto the coating steel roller, thereby blocking the die lip and allowing the slurry to circulate in the die. The disadvantage of this method of blocking the die lip is that when the foam is placed, there is a possibility of introducing debris that damages the die lip and the coating steel roller. Utility Model Content

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a device for automatically sealing a lip of a slurry circulating in a die head of a coating machine.

[0004] The technical solution of the utility model is as follows:

[0005] The top end of the sliding seat is hinged on the bottom of the sliding seat, and the top end of the sliding seat is hinged on the bottom of the sliding seat, and the top end of the sliding seat is upwards, one end of the compression spring is installed on the sliding seat, and the other end presses on the right side surface of the swing link, the pressure wheel is rotatably mounted on the pressure wheel seat and rolls on the left side of the swing link, and the blocking rod is installed on the top end of the swing link, and a blocking rubber block is provided on the right side of the blocking rod.

[0006] Preferably, the right side of the sliding seat is concave inward to form a concave hole, and the compression spring is installed in the concave hole.

[0007] Preferably, the blocking rubber block is fixed to the blocking rod via a blocking rubber strip.

[0008] Preferably, the blocking rubber block is in an inverted L-shape, with its horizontal end and vertical end respectively attached to the top and right side of the blocking rod.

[0010] Preferably, the automatic lip sealing device for slurry circulation in the coater die head further comprises a protective cover, which is mounted on the mounting seat and covers the outer sides of the swing link, the pressure wheel, the sliding seat and the pressure wheel seat.

[0011] Compared with the prior art, the beneficial effect of the present invention is that the present invention utilizes the cylinder to extend upward to drive the swing connecting rod to move upward and rotate to the right under the action of the pressure wheel so that the sealing rod at the top of the swing connection is close to the lip of the coating die head, so that the sealing rubber block on the sealing rod is pressed into the lip, sealing the lip, so that the slurry forms an internal circulation in the coating die head, and there is no need to move the coating equipment, ensuring that the coating equipment can be operated at any time. At the same time, it avoids the phenomenon that traditional foam sealing may bring in debris and damage the die head lip and the coating steel roller, thereby effectively protecting and improving the sealing efficiency.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0021] Example 1

[0022] like Figures 1 to 6As shown, the lip automatic sealing device 40 for the slurry circulation in the die head of the coating machine of this embodiment includes a mounting seat 1, a cylinder 2, a swing link 3, a pressure wheel 4, a guide rail 5, a sliding seat 6, a pressure wheel seat 7, a compression spring 8 and a blocking rod 9. The middle part of the swing link 3 is bent to the right and then vertically upward, and a short inclined surface 31 inclined to the upper right is formed in the middle part of the swing link 3. The guide rail 5 is vertically mounted on the mounting seat 1, and the sliding seat 6 is slidably set on the guide rail 5. The cylinder 2 is mounted on the mounting seat 1, and its telescopic end is vertically upward and hinged at the The top of the sliding seat 6, the pressure roller seat 7 is horizontally installed on the mounting seat 1 and is located above the sliding seat 6, the bottom end of the swing link 3 is hinged to the bottom of the sliding seat 6, and its top end is upward, one end of the compression spring 8 is installed on the sliding seat 6, and its other end is pressed on the right side of the swing link 3, the pressure roller 4 is rotatably installed on the pressure roller seat 7 and rolls on the left side of the swing link 3, the blocking rod 9 is installed on the top of the swing link 3, and a blocking rubber block 10 is provided on the right side of the blocking rod 9. This device can be operated individually or in combination. When operated individually, the middle part of the blocking rod is fixed to the top of the swing link; when operated in combination, the two ends of the blocking rod are respectively fixed to the tops of the two swing links. When the lip needs to be sealed, the coating die head is in a retracted state, the coating die head 20 leaves the coating steel roller 30, the telescopic end of the cylinder 2 extends upward, driving the sliding seat 6 to move upward along the guide rail 5 on the mounting seat 1, and the sliding seat 6 drives the swing link 3 to move upward. When the middle part of the swing link 3 slides to the pressure wheel 4, the middle part of the swing link 3 is bent to the right and then vertically upward. The pressure wheel 4 presses the swing link 3 to deflect to the right, so that the blocking rod 9 on the swing link 3 is close to the lip, and finally the blocking rod 9 is pressed against the lip. The sealing rubber block 10 on 9 is pressed against the lip to seal the lip; when the inspection is completed and coating is required, the telescopic end of the cylinder 2 moves downward to drive the sliding seat 6 to move downward along the guide rail 5, so that the swing link 3 drives the sealing rod 9 to move downward so that the sealing rubber block 10 on the sealing rod 9 leaves the lip. When the middle part of the swing link 3 passes the pressure wheel 4, the compression spring 8 on the sliding seat 6 applies a leftward force to the swing link 3 to deflect the swing link 3 and turn it vertically upward, thereby completing the overall reset. The automatic lip sealing device for slurry circulation in the coating die head of this embodiment enables the slurry to form an internal circulation in the coating die head, without the need to move the coating equipment, ensuring that the coating equipment can be operated at any time. At the same time, it avoids the phenomenon that the die head lip and the coating steel roller may be damaged by foreign matter brought in by traditional foam sealing, thereby effectively improving the sealing efficiency.

[0023] In this embodiment, the right side of the sliding seat 6 is recessed inward to form a recessed hole 61, into which the compression spring 8 is mounted, facilitating installation of the compression spring 8. The sealing rubber block 10 is secured to the sealing rod 9 via a sealing rubber strip 11, ensuring the sealing performance of the sealing rubber block 10. The sealing rubber block 10 is in an inverted L-shape, with its horizontal and vertical ends respectively attached to the top and right side of the sealing rod 9, ensuring a more secure installation of the sealing rubber block 10.

[0024] In this embodiment, a cylinder seat 12 is provided on the left side of the bottom end of the mounting base 1, and the cylinder 2 is mounted on the cylinder seat 12, which facilitates the installation of the cylinder. The automatic lip sealing device for slurry circulation in the coating machine die head also includes a protective cover 13. The protective cover 13 is mounted on the mounting base 1 and covers the outer sides of the swing link 3, the pressure roller 4, the sliding seat 6, and the pressure roller seat 7, thereby protecting the entire device and improving safety.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
