The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] For example, see Figure 1-4 The present invention provides a technical solution: a uniform glue coating device for producing an air filter element, comprising a control box 1, and also comprising a uniform distribution component 6.

[0039] A connected collecting groove is provided at the middle of the back of the working box 5 and the top of the front of the collecting box 603. By providing the collecting groove, the glue collected on the top of the guide plate 601 can be uniformly recovered through the collecting groove.

[0040] When the annular filter element rotates, glue overflows. At this time, the overflowing glue accumulates on the top of the guide plate 601 along the inner wall of the working box 5. By setting the guide plate 601 to be inclined and cooperating with the guide ring plate 602, the glue that is thrown out can be guided and uniformly directed to flow into the collection box 603. The device can uniformly collect the excess overflowing glue to avoid glue waste.

[0041] For example 2, please refer to Figure 1-9On the basis of the first embodiment, the present invention provides a technical solution: it also includes a positioning adjustment component 7, which is composed of a driving motor 701, a rotating disk 702, a driving cylinder 703, an electric telescopic rod 704, a lifting adjustment plate 705, an adjustment frame 706, a connecting plate 707, a force frame 708, a moving frame 709 and a connecting rod 710.

[0042] The driving motor 701 is fixedly connected to the top left side of the control box 1, and the driving motor 701 has an output shaft. The rotating disk 702 is fixedly connected to the output shaft of the driving motor 701, and the driving cylinder 703 is fixedly connected to the bottom of the rotating disk 702. The electric telescopic rod 704 is fixedly connected to the middle of the top of the driving cylinder 703, and the electric telescopic rod 704 has a telescopic end. The lifting adjustment plate 705 is fixedly connected to the telescopic end of the electric telescopic rod 704, and the adjusting frame 706 is fixedly connected to the outside of the lifting adjustment plate 705. The connecting plate 707 is rotatably connected to the middle part of the adjusting frame 706. The force-bearing frame 708 is rotatably connected to the side of the connecting plate 707 away from the adjusting frame 706. The moving frame 709 is fixedly connected to the bottom of the force-bearing frame 708, and the connecting rod 710 is fixedly connected to the side of the moving frame 709 away from the driving cylinder 703. The electric telescopic rod 704 can drive the lifting adjustment plate 705 to rise and fall in the driving cylinder 703.

[0043] It also includes a protection component 8, which consists of a movable pulley 801, a movable arc plate 802, a fixed storage plate 803, a spring 804, a movable limiting plate 805 and a protection baffle 806.

[0044] The movable pulley 801 is rotatably connected to the bottom of the movable frame 709, the movable arc plate 802 is fixedly connected to the connecting rod 710, the fixed storage plate 803 is fixedly connected to the inner top of the movable arc plate 802, the spring 804 is fixedly connected to the left side of the fixed storage plate 803, the movable limit plate 805 is fixedly connected to the other end of the spring 804, the protective baffle 806 is fixedly connected to the top of the movable limit plate 805, and the connecting rod 710 can synchronously drive the movable arc plate 802 to move when moving.

[0045] The output shaft of the driving motor 701 passes through the top inner wall of the control box 1, the bottom inner wall of the working box 5 and the middle of the guide plate 601 and extends to the top of the guide plate 601 and is fixedly connected to the bottom of the rotating disk 702. The driving motor 701 can drive the rotating disk 702 to rotate when working.

[0046] A guide groove is fixedly connected to the bottom of the outer side of the driving cylinder 703. The force frame 708, the movable frame 709, the connecting rod 710 and the movable pulley 801 are all built into the guide groove. A movable slider corresponding to the guide groove is arranged on the outer side of the movable frame 709. The movable frame 709 is slidably connected to the inner wall of the guide groove through the movable slider, and the guide groove can support and guide the movable frame 709.

[0047] The telescopic end of the electric telescopic rod 704 passes through the top of the driving cylinder 703 and extends into the driving cylinder 703 to be fixedly connected to the top of the lifting adjustment plate 705. The outer wall of the driving cylinder 703 is provided with a rectangular groove to accommodate the lifting and lowering of the adjustment frame 706. The adjustment frame 706 is built into the rectangular groove, which enables the adjustment frame 706 to be lifted and lowered on the outer wall of the driving cylinder 703.

[0048] The bottom of the movable arc plate 802 away from the driving cylinder 703 is fixedly connected to a supporting bottom plate, and a limiting groove is opened in the middle of the fixed storage plate 803. The spring 804 and the movable limiting plate 805 are both built into the limiting groove. By setting the limiting groove, the moving direction of the spring 804 and the movable limiting plate 805 can be limited.

[0049] When it is necessary to apply glue to the annular filter element in the air filter, the electric telescopic rod 704 is controlled to work, so that the electric telescopic rod 704 can drive the lifting adjustment plate 705 to descend in the driving cylinder 703 during operation. At the same time, the lifting adjustment plate 705 drives the adjustment frame 706 to move downward synchronously when descending, so that the adjustment frame 706 squeezes the middle connecting plate 707. When the connecting plate 707 is stressed, the force-bearing frame 708 on the other side of the connecting plate 707 is squeezed, so that the bottom moving frame 708 9 is subjected to force synchronously, at this time, the moving pulley 801 at the bottom of the moving frame 709 slides on the inner wall at the bottom of the rotating disk 702, and at the same time, the moving frame 709 slides outward inside the guide groove, so that the moving arc plate 802 on the other side of the connecting rod 710 moves synchronously, and then the annular filter element is placed on the outside of the moving arc plate 802. At this time, the supporting bottom plate on the outside of the moving arc plate 802 can support the bottom of the annular filter element and position the annular filter element to prevent displacement when it is subsequently coated with glue.

[0050] By adjusting the position of the drive seat 3, the glue dripping position of the glue spray head 4 can be controlled so that the glue in the glue spray head 4 can be smeared on the inner side of the top of the annular filter element. Then the glue spray head 4 extracts the glue stored in the glue storage box 2 and drips it on the top of the annular filter element. Then the drive motor 701 is controlled to work so that the drive motor 701 can drive the rotating disk 702 to rotate slowly. After the rotating disk 702 rotates one circle in the working box 5, the glue in the glue spray head 4 can be smeared on the top of the annular filter element for one circle. Then the drive motor 701 is started so that the drive motor 701 can quickly drive the rotating disk 702 to rotate, thereby increasing the centrifugal force on the rotating disk 702. At this time, the glue on the top of the annular filter element moves outward under the action of centrifugal force, so that the top of the annular filter element can be smeared with the glue by centrifugal force, so that the glue is more evenly applied.

[0051] When the driving motor 701 controls the rotating disk 702 to rotate, the centrifugal force on the rotating disk 702 increases, which can compress the spring 804. At the same time, the movable limit plate 805 moves outward inside the fixed storage plate 803, so that the protective baffle 806 covers the upper side of the annular filter element, which can block the glue splashing during rotation and prevent the glue from splashing everywhere.

[0052] When it is necessary to evenly distribute the glue on the top of the annular filter element, the driving motor 701 is controlled to drive the rotating disk 702 to rotate slowly. At this time, the centrifugal force on the rotating disk 702 is reduced, and it is difficult to compress the spring 804. When the spring 804 recovers elastically, the protective baffle 806 is moved away from the top of the annular filter element again, and then the telescopic driving plate 604 is controlled to work. The telescopic driving plate 604 drives the lifting member 605 to move to the upper side of the annular filter element, and then the lifting member 605 is started, which can enable the lifting member 605 to drive the lifting frame 606 and the glue-distributing roller 607 to descend, so that the glue-distributing roller 607 contacts the top of the annular filter element, and when the driving motor 701 drives the rotating disk 702 to rotate, the glue adhering to the top of the annular filter element is slowly evenly distributed.
