Description

Technical Field

[0001] The present invention relates to the field of filter element processing equipment, and particularly relates to a fully automatic filter element net covering machine. Background Art

[0002] For tubular products such as activated carbon filter elements and pleated filter elements, in order to protect their service life, a layer of non-woven fabric or pleated film is usually wrapped to intercept sediment in water to prevent blockage of the pores of the activated carbon and avoid affecting the filtering performance of the activated carbon.

The second pressing head 402 is opposite to the first pressing head 304 and is arranged coaxially.

[0048] like Figure 8 and 9 As shown, the net-pulling device 5 is located between the net-supporting device 3 and the material-pushing and positioning device 4, and a first reciprocating mechanism 6 is arranged on the top of the net-pulling device 5, and the first reciprocating mechanism 6 is arranged horizontally. The net-pulling device 5 includes a net-pulling seat plate 501, and a clamping plate 502 and a net-pressing cylinder 503 are arranged on the bottom surface of the net-pulling seat plate 501. A mesh hole 504 is arranged on the clamping plate 502, and the mesh hole 504, the net-pressing cylinder 503 and the second pressing head 402 are arranged coaxially. The front part of the net-pressing cylinder 503 is in an arc shape, which is convenient for extrusion and matching with the mesh hole 504. The side of the net-pressing cylinder 503 is provided with a second telescopic driving member 505 that drives its axial movement. Specifically, the telescopic end of the second telescopic driving member 505 is connected to the clamping plate 502, and the body of the second telescopic driving member 505 is connected to the net-pressing cylinder 503.

[0049] As Figure 10 shown, the first reciprocating mechanism 6 includes two reciprocating guide rods 601 arranged side by side horizontally. The net-pulling seat plate 501 is slidably connected to the two reciprocating guide rods 601. Both ends of the two reciprocating guide rods 601 are respectively connected to the workbench 1 through brackets 602. Above the two reciprocating guide rods 601, a lead screw 603 is arranged side by side. Both ends of the lead screw 603 are connected to the brackets 602 through lead screw seats 604. One end of the lead screw 603 is power-connected to a lead screw driving device 605, and the lead screw driving device 605 is connected to the bracket 602. A driving block 606 is threadedly connected to the lead screw 603, and the driving block 606 is fixedly connected to the net-pulling seat plate 501.

[0050] In this embodiment, the sleeve 301 is fixedly connected to the two reciprocating guide rods 601 through the first seat plate 9. The servo motor 805 is installed on the first seat plate 9 through a motor connecting plate, and the baffle 309 is installed and fixed on the first seat plate 9 through a bolt assembly. The first telescopic driving member 401 is fixedly connected to the two reciprocating guide rods 601 through the second seat plate 10.

[0051] In this embodiment, the first telescopic driving member 401, the second telescopic driving member 505, and the third telescopic driving member 203-3 are all air cylinders. The lead screw driving device 605 adopts a driving combination form of a synchronous transmission belt and a servo motor.

[0052] The working process of the present invention:

[0053] Before the machine runs, the filter element net sleeve passes through the net-feeding hole 310 and the net-passing channel 303 in sequence and is stretched and sleeved on the net-supporting shuttle 302. The front end of the filter element net sleeve extends to the first shield 307.

[0054] Then, the net-pulling device 5 approaches the net-supporting device 3 under the drive of the first reciprocating mechanism 6. The net-passing hole 504 of the net-pulling device 5 is sleeved on the outside of the first shield 307. After the pressing net cylinder 503 presses the first shield 307 to slide backward along the first press head guide rod 305 for a certain distance, the net sleeve is thus expanded from the inside. During the process of expanding the net sleeve, the pressing net cylinder 503 and the net-passing hole 504 cooperate to clamp the expanded net sleeve. During the process of the pressing net cylinder 503 pressing the first shield 307 to move backward, it will drive the net-supporting shuttle 302 to move backward as a whole for a certain distance. Since a baffle 309 is provided at the rear part of the sleeve 301, the baffle 309 abuts against the rear end of the net-supporting shuttle 302, restricting the net-supporting shuttle 302 from continuing to move backward and preventing the net-supporting shuttle 302 from blocking the net-passing channel 303.

[0055] The object to be installed (filter element) is first placed on the first lifting grooves 202 of the two lifting pallets 201 in an orderly manner through a series of mechanisms. The first lifting assembly 203 operates, and the object to be installed (filter element) is lifted to the preliminary position of the net covering through the first lifting movable plate 203-4 and the connected lifting pallet 201. At this time, the first telescopic driving member 401 of the feeding and positioning device 4 provides power to drive the second pressure head 402 to push the object to be installed (filter element) through the net pressing cylinder 503 and then to the net supporting device 3. The first pressure head 304 at the front end of the net supporting device 3 and the second pressure head 402 at the front end of the feeding and positioning device 4 cooperate to jointly clamp the object to be installed (filter element) in the middle. After that, the first lifting assembly 203 drives the lifting pallet 201 to return to its original position.

[0056] Then, the net pulling device 5 moves backward under the drive of the first reciprocating mechanism 6. During the backward movement of the net pulling device 5, the expanded net sleeve is clamped and pulled to the end of the object to be installed (filter element). During the process of the net pulling device 5 pulling the net sleeve, the net sleeve drives the first pressure head 304 to extrude the filter element through the net supporting shuttle 302, so that the whole net supporting shuttle 302 moves forward a certain distance. In this way, the rear part of the net supporting shuttle 302 is separated from the baffle 309, avoiding the net sleeve being stuck at the net feeding hole 310.

[0057] After the filter element is completely wrapped by the net sleeve, the cutting mechanism 8 arranged on the net supporting device 3 starts to operate. Specifically, the servo motor 805 drives the first synchronous wheel 802 to rotate through the synchronous belt 801. The knife throwing frame 806 on one side of the first synchronous wheel 802 drives the cutting edge of the cutting knife 807 to perform circular cutting on the net sleeve under the action of centrifugal force, thereby cutting off the net sleeve.

[0058] After that, the first lifting assembly 203 acts to drive the lifting pallet 201 to rise and hold the filter element with the net sleeve. Then, the second pressure head 402 of the feeding and positioning device 4 is reset. At this time, the net pulling device 5 continues to drive the filter element with the net sleeve to move backward a certain distance to reset the shifted filter element. After that, after the net pulling device 5 releases the net sleeve, the first lifting assembly 203 drives the filter element with the net sleeve to descend and return to its original position.

[0059] Embodiment 2

[0060] In this embodiment, a transporting device 7 is designed on the basis of the technology of Embodiment 1. Through the transporting device 7, the object to be installed (filter element) can be placed in the first lifting groove 202 of the lifting pallet 201, and the filter element with the net sleeve can also be taken out from the first lifting groove 202 of the lifting pallet 201 through the transporting device 7.

[0061] As Figures 11 to 13As shown in the figure, specifically, the conveying device 7 includes a second reciprocating mechanism 701 and two bracket fixed plates 702 arranged side by side; the second reciprocating mechanism 701 is longitudinally arranged between the two lifting pallets 201, two bracket moving plates 703 arranged side by side are provided on the moving part of the second reciprocating mechanism 701, and a second lifting assembly 704 is provided at the bottom of the second reciprocating mechanism 701.

[0063] When the conveying device 7 works, the second lifting assembly 704 drives the bracket moving plate 703 to rise, lifts the filter element from the bracket fixed plate 702, then the second reciprocating mechanism 701 drives the bracket moving plate 703 to move forward, and then, the second lifting assembly 704 resets and places the lifted filter element in the next second lifting groove 705 of the bracket fixed plate 702, and then continues to repeat all the above actions, thus realizing the conveying of the filter element.

[0064] In this embodiment, the second lifting assembly 704 includes a second lifting movable plate 704-1, the second lifting movable plate 704-1 is located above the workbench 1, the second reciprocating mechanism 701 is arranged on the top of the second lifting movable plate 704-1, second lifting guide sliding rods 704-2 are arranged at both ends of the bottom of the second lifting movable plate 704-1, the second lifting guide sliding rods 704-2 are slidably connected to the workbench 1, and the bottom of the second lifting movable plate 704-1 is connected to the telescopic end of a fourth telescopic driving member 704-3.

[0065] In this embodiment, the second reciprocating mechanism 701 is a slide cylinder.
