[0034] like Figures 1 to 7 As shown, the present application provides a tear-resistant polyester needle felt filter bag forming device, comprising a bracket 100, a rotating shaft 200 is rotatably connected to the bracket 100, and a primary forming component 300 and a secondary forming component 400 are respectively connected to both ends of the rotating shaft 200;

[0035] The primary forming assembly 300 includes a plurality of primary forming plates 310 arrayed on the outer circumference of the rotating shaft 200, each of which is provided with a primary forming groove 320, and the primary forming groove 320 is in an arc shape larger than half of a semicircle;

[0036] The secondary molding assembly 400 includes a plurality of secondary molding plates 410 arrayed on the outer circumference of the rotating shaft 200 . The plurality of secondary molding plates 410 are each provided with a secondary molding groove 420 . The secondary molding groove 420 is in an arc shape that is larger than a full circle.

[0037] Further specific description: Through the design of the primary molding component 300 and the secondary molding component 400, it is convenient to provide preliminary molding and transition molding for the filter bag, and the molding effect is good, so as to better carry out subsequent molding and sewing operations; in addition, the edges of the groove walls of the primary molding groove 320 and the secondary molding groove 420 are chamfered, which can protect the filter bag and avoid scratches.

[0038] Specifically, the number of the primary forming plates 310 and the secondary forming plates 410 is the same, and their positions correspond one to one, and the number of the primary forming grooves 320 and the secondary forming grooves 420 is the same, and their positions correspond one to one;

[0039] The primary forming grooves 320 on the plurality of primary forming plates 310 are of different sizes, and the secondary forming grooves 420 on the plurality of secondary forming plates 410 are of different sizes.

[0040] To be further described in detail: through the above structural design, each filter bag passing through the primary molding groove 320 can enter the corresponding secondary molding groove 420 to obtain a molding transition, with a better molding effect, and can enter the circular molding cylinder used for molding filter bags in the prior art with a better molding shape for further molding; in addition, the corresponding primary molding grooves 320 and secondary molding grooves 420 on the left and right can perform molding operations on filter bags of the same size.

[0041] Specifically, Figure 2 As shown, the primary molding assembly 300 is fixedly connected to the rotating shaft 200;

[0042] The primary forming assembly 300 further includes a fixing ring 330 fixedly sleeved on the outside of the rotating shaft 200 . The fixing ring 330 has a plurality of connecting rods in a fixed array outside. The connecting rods are fixedly connected to the primary forming plate 310 .

[0043] To further explain in detail: the primary forming assembly 300 is used for the preliminary forming of the filter bag, and the filter bag passes through the primary forming groove 320 on the primary forming plate 310.

[0044] Specifically, Figure 3 As shown, the secondary molding assembly 400 is slidably connected to the rotating shaft 200;

[0045] The secondary forming assembly 400 further includes a sliding ring 430 slidably mounted on the outside of the rotating shaft 200 . The sliding ring 430 has a plurality of connecting bars in a fixed array outside thereof. The connecting bars are fixedly connected to the secondary forming plate 410 .

[0046] To further explain in detail: the secondary molding assembly 400 is used for re-molding of the filter bag. After passing through the primary molding groove 320, the filter bag passes through the secondary molding groove 420 to enhance the molding effect and play a role of transition molding.

[0047] Specifically, Figure 1 and Figure 7 As shown, a slider 431 is fixed symmetrically to the lower end of the inner wall of the sliding ring 430 , and a sliding groove 210 matching the slider 431 is transversely opened on the rotating shaft 200 , and the slider 431 is slidably connected inside the sliding groove 210 .

[0048] Further specific explanation: the slide groove 210 and the slider 431 are designed to be biased towards the lower end, which can reduce the direct falling of dust and reduce the number of cleaning times; in addition, the slider 431 and the slide groove 210 can enhance the stability of the sliding ring 430 sliding on the rotating shaft 200, so that the secondary molding component 400 will not flip freely on the rotating shaft 200, and thus the primary molding plate 310 and the secondary molding plate 410 can always maintain a corresponding relationship in position, which is beneficial to the stability of the filter bag molding.

[0049] Specifically, Figures 4 to 6 As shown, it also includes a driving component 500, which includes a driven rod 510 fixed to one end of the rotating shaft 200, the other end of the driven rod 510 extends through the bracket 100 to the outside of the bracket 100, and is fixed with a driven wheel 520, an active rod 530 is rotatably connected to the bracket 100, and a driving wheel 540 is fixed to the active rod 530, and the driving wheel 540 and the driven wheel 520 are meshingly connected.

[0050] Further specific description: The driving assembly 500 can drive the rotating shaft 200 to rotate, so that the primary molding assembly 300 and the secondary molding assembly 400 are rotated to a suitable angle, which facilitates the primary molding plate 310 and the secondary molding plate 410 of suitable sizes to be flipped to the top, so as to facilitate the molding and passing of the filter bag.

[0051] Specifically, the driven wheel 520 is fixed with full teeth 521 on its circumference, and the driving wheel 540 is fixed with quarter teeth 541 on its circumference. The full teeth 521 and the quarter teeth 541 are meshed and connected, and three quarters of the full teeth 521 and the quarter teeth 541 on the circumference of the driving wheel 540 are idle.

[0052] There are four primary forming plates 310 and four secondary forming plates 410 .

[0053] Further specific explanation: In the initial state, one of the primary forming plates 310 and the corresponding secondary forming plate 410 are directly above the rotating shaft 200. When it is necessary to replace the primary forming plate 310 and the corresponding secondary forming plate 410 of other sizes, since the driving wheel 540 can drive the driven wheel 520 to rotate a quarter of a circle, that is, 90°, for each rotation of the driving wheel 540, the primary forming plate 310 and the secondary forming plate 410 of another size can be rotated to directly above the rotating shaft 200 for use in filter bag molding. This design can ensure that the primary forming plates 310 and the secondary forming plates 410 of the corresponding sizes are not tilted and are directly above the rotating shaft 200, and the molding of the filter bag is also more stable.

[0054] Specifically, the active rod 530 is slidably connected with a U-shaped rod 550, and the other end of the U-shaped rod 550 is movably inserted into the bracket 100;

[0055] The bracket 100 is provided with an opening, and one end of the U-shaped rod 550 away from the driving wheel 540 is movably inserted into the opening;

[0056] To be further described in detail: one end of the U-shaped rod 550 is inserted into the opening, so that the U-shaped rod 550 can be stable and not shake, thereby making the active rod 530 structurally stable, thereby ensuring that the driven rod 510 and the rotating shaft 200 are also structurally stable and will not drive the primary molding plate 310 and the secondary molding plate 410 to rotate, thereby ensuring the stability of the filter bag during the molding process.

[0057] The active rod 530 is provided with a slot 531, one end of the U-shaped rod 550 is slidably connected inside the slot 531, limiting slots 532 are provided on both sides of the inner wall of the slot 531, one end of the U-shaped rod 550 is located inside the slot 531 and a limiting plate 533 is fixed symmetrically front and back, and the limiting plate 533 is slidably connected inside the limiting slot 532.

[0058] To further explain in detail, the limiting groove 532 has a limiting effect on the limiting plate 533 , thereby preventing the U-shaped rod 550 from escaping from the inside of the groove 531 .

[0059] When the tear-resistant polyester needle-punched felt filter bag forming equipment of the embodiment of the present application is actually used: according to the filter bag, a suitable primary forming groove 320 and a corresponding secondary forming groove 420 are selected, and the operation is as follows: the U-shaped rod 550 is held and pulled outward, and the limiting plate 533 slides inside the limiting groove 532, and at the same time, the other end of the U-shaped rod 550 is separated from the opening, and the active rod 530 is twisted counterclockwise for one circle, and the quarter teeth 541 on the active wheel 540 are meshed with the full teeth 521. After the full teeth 521 drive the driven wheel 520 to rotate 90°, the remaining three quarters of the active wheel 540 idle, and at the same time, the U-shaped rod 550 also rotates one circle synchronously with the active rod 530, and one end of the U-shaped rod 550 is inserted into the opening again for limiting, and synchronously, the driven wheel 520 drives the rotating shaft 200 to rotate synchronously by 90°, and the suitable primary forming groove 320 and the corresponding secondary forming groove 420 are rotated to just above the rotating shaft 200;

[0060] The filter bag is then formed as follows: one end of the filter bag passes through the primary forming groove 320 and then continues to pass through the secondary forming groove 420, so that the subsequent filter bag passes through the circular forming cylinder in the prior art and is then sewn.

[0061] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
