[0040] The following will further describe the present invention in detail with reference to the embodiments given in the accompanying drawings.

[0041] Refer to Figures 1-8 As shown, the multi-station trimming machine for the filter housing of this embodiment includes: a frame 1 and a stamping mechanism 2 provided on the frame 1. A rotating disc 11 is provided on the frame 1. A stamping hole 111 is provided on the rotating disc 11. A stamping die 112 is provided outside the stamping hole 111 on the rotating disc 11. The stamping holes 111 are arranged in a circle. The stamping mechanism 2 is provided above the stamping hole 111. The rotating disc 11 rotates at intervals so that the stamping holes 111 sequentially pass under the stamping mechanism 2. A cutting assembly 3 is provided on the stamping mechanism 2. The cutting assembly 3 is used for cutting waste. A blanking device 4 is provided on the frame 1. The blanking device 4 includes a housing blanking mechanism 41 and a waste blanking mechanism 42. The housing blanking mechanism 41 includes:

[0042] A housing blanking rod 411, which is liftably provided on the frame 1. The housing blanking rod 411 is provided on the lower side of the rotating disc 11. When any stamping hole 111 is directly below the stamping mechanism 2, another stamping hole 111 is directly above the housing blanking rod 411;

[0043] The housing push rod 412 is horizontally slidably arranged on the frame 1. The housing push rod 412 is located above the rotary disk 11 and is arranged adjacent to the housing blanking rod 411.

[0044] The waste blanking mechanism 42 includes:

[0045] The cutting disk 421 is arranged outside the stamping die 112.

[0046] The waste chutes 422 are arranged on both sides of the cutting disk 421. The waste chutes 422 are inclined, gradually sloping downward from inside to outside.

[0047] The waste collection box 423 is arranged on one side of the frame 1 and is located below the rotary disk 11.

[0048] The waste push plate 424 is movably arranged above the cutting disk 421. The waste push plate 424 is linked with the housing blanking rod 411.

[0049] Through the above technical solution, the stamping holes 111 are arranged along the central circumference of the rotary disk 11, and the angle of one rotation of the rotary disk 11 is the central angle of adjacent stamping holes 111. When processing the filter housing with this equipment, the filter housing to be processed is manually grabbed and placed into the stamping die 112, or the filter housing to be processed is placed into the stamping die 112 by the feeding equipment; the rotary disk 11 rotates, driving the stamping holes 111 and the stamping die 112 to rotate, driving the stamping die 112 to pass through the stamping mechanism 2 in sequence and stay at this position. The stamping mechanism 2 and the cutting assembly 3 move in sequence (while the stamping mechanism 2 and the cutting mechanism are moving, the housing blanking mechanism 41 operates), completing the waste stamping of the filter housing and the cutting of the waste. Then the stamping mechanism 2 and the cutting assembly 3 return to their original positions, the rotary disk 11 rotates, moving the next stamping hole 111 under the stamping mechanism 2, and the stamping hole 111 and the stamping die 112 in front of the housing blanking mechanism 41 move to the position of the housing blanking mechanism 41. The operation mode of the housing blanking mechanism 41 is as follows: the housing blanking rod 411 rises, pushing the filter housing that has completed stamping above to rise. When the filter housing completely leaves the stamping die 112, the housing push rod 412 moves, pushing the rising filter housing away from the stamping die 112 and falling to the side and being pushed into the external conveyor belt / external collection device; then the housing blanking rod 411 and the housing push rod 412 return to their original positions, waiting for the next housing blanking.

[0050] It should be noted that the cutting disk 421 cooperates with the cutting assembly 3 to cut the waste. When the housing push rod 412 rises, it simultaneously drives the waste push plate 424 to rotate, causing the waste on the waste push plate to fall into the waste chutes 422, and then with the next rotation of the rotary frame, it outputs it into the waste collection box 423.

[0051] This device can continuously process filter housings during production, and collect filter housings and waste materials while stamping. There is no need for manual collection of waste materials or manual removal of the filter housings that have completed stamping, with high efficiency.

[0052] As a specific embodiment of the improvement, a first through hole 51 is provided on the cutting disc 421, a second through hole 52 is provided on the stamping die 112, a third through hole 53 is provided on the rotating disc 11. The first through hole 51, the second through hole 52, and the third through hole 53 are coaxially arranged, and the diameters of the first through hole 51, the second through hole 52, and the third through hole 53 are equal. A blanking driven rod 54 is slidably connected in the first through hole 51. The upper end of the blanking driven rod 54 passes through the first through hole 51 and is rotatably connected to the waste pushing plate 424. The blanking driven rod 54 extends downward through the third through hole 53. A waste driving rod 55 extending vertically upward is provided on the side of the housing blanking rod 411.

[0053] Through the above technical solution, the process of the housing blanking rod 411 rising and driving the waste pushing plate 424 is as follows: when the housing blanking rod 411 rises, it drives the waste driving rod 55 to rise until the waste driving rod 55 abuts against the blanking driven rod 54. Then the housing blanking rod 411 continues to rise and drives the blanking driven rod 54 to rise through the waste driving rod 55, thereby driving the waste pushing plate 424 to rotate and pushing the waste on the waste pushing plate 424 into the waste chute 422. Then it moves into the waste collection box 423 through the waste chute 422.

[0054] When the housing blanking rod 411 descends, it drives the waste driving rod 55 to descend. At this time, the waste pushing plate 424 and the driven blanking rod reset under the action of gravity.

[0055] Specifically, a counterweight block 541 is provided at the lower end of the blanking driven rod 54. The contact area between the counterweight block 541 and the waste driving rod 55 is large, with high stability when driving the blanking driven rod 54, and the counterweight at the lower end of the blanking driven rod 54 is increased to assist the blanking driven rod 54 in quickly returning to its position, further improving production efficiency.

[0056] In addition, the counterweight block 541 limits the maximum rising distance of the blanking driven rod 54 (when rising to the highest position, the counterweight block 541 abuts against the rotating disc 11), improving the stability during use.

[0057] As a specific embodiment of the improvement, a waste blanking notch 4211 is provided on the cutting disc 421. The position of the waste blanking notch 4211 corresponds to the position of the waste pushing plate 424. The waste pushing plate 424 is arc-shaped, and waste driving rods 55 are connected to both sides of the waste pushing plate 424.

[0058] Through the above technical solution, the waste blanking notch 4211 is located on the path of rotation of the waste push plate 424. When the blanking follower rod 54 rises to drive the waste push plate 424 to rotate, the waste push plate 424 has a large rotation amplitude, and can push the waste into the waste chute 422 faster and better, improving the stability during use.

[0059] The waste push plate 424 is arranged in an arc shape, similar to the shape of the waste, so that the waste can be pushed down more stably during the rotation of the waste push plate 424; both sides of the waste push plate 424 are connected to the waste drive rod 55, so that the position of the waste push plate 424 is stable during the rotation process.

[0060] As a specific implementation of the improvement, the stamping mechanism 2 includes:

[0061] A stamping cylinder 21, vertically and fixedly arranged on the frame 1;

[0062] A stamping seat 22, connected to the stamping cylinder 21 and driven to lift by the stamping cylinder 21;

[0063] The cutting assembly 3 includes:

[0064] A cutting cylinder 31, vertically and fixedly arranged on the frame 1;

[0065] A cutting sleeve 32, arranged outside the stamping seat 22 and slidably connected to the stamping seat 22. The cutting sleeve 32 is connected to the cutting cylinder 31 and driven to lift by the cutting cylinder 31. An upper cutting knife 33 is arranged on the lower side of the cutting sleeve 32;

[0066] A lower cutting knife 34 is arranged on the cutting disc 421. The movement path of the upper cutting knife 33 is adjacent to that of the lower cutting knife 34. An auxiliary knife 35 is arranged outside the stamping die 112, and the position of the auxiliary knife 35 corresponds to the position of the lower cutting knife 34.

[0067] Through the above technical solution, the operation process of the stamping mechanism 2 and the cutting mechanism is as follows: The stamping cylinder 21 operates to drive the stamping seat 22 to descend. The stamping seat 22 descends to cooperate with the lower stamping die 112 to separate the filter housing from the waste. At this time, the filter housing is located in the stamping die 112, and the waste is located outside the stamping die 112; then the cutting assembly 3 operates. The cutting cylinder 31 drives the cutting sleeve 32 to descend. The cutting sleeve 32 descends to drive the upper cutting knife 33 to descend, and cooperate with the lower cutting knife 34 below to cut the waste. The auxiliary knife 35 cooperates with the upper cutting knife and the lower cutting knife to completely cut the waste.

[0068] Specifically, there are two sets of upper cutting knives 33, lower cutting knives 34, and auxiliary knives 35, which are located on the radius of the rotating disk 11 and bisect the waste materials. Then the waste material push plate 424 moves to drive two pieces of waste materials onto the waste material chute 422. With the next operation of the rotating disk 11, the generated centrifugal force causes the waste materials to fall into the waste material collection box 423. There is no need to additionally set a driving device to push the waste materials from the waste material chute 422 into the waste material collection box 423, reducing energy consumption and having high stability during use.

[0069] As a specific embodiment of the improvement, a push groove 4121 is provided on the housing push rod 412, and a flexible gasket 4122 is provided in the push groove 4121.

[0070] Through the above technical solution, when the housing push rod 412 moves to push the filter housing to drop, the filter housing is located in the push groove 4121 and is pushed down, making the landing point of the filter housing stable and accurate, facilitating collection. The flexible gasket 4122 abuts against the filter housing during the pushing process, avoiding wear on the surface of the filter.

[0071] As a specific embodiment of the improvement, two positioning columns 61 are provided on the frame 1, positioning seats 62 are provided on the positioning columns 61, a positioning rod 63 is vertically arranged between the two positioning columns 61, a lifting seat 64 is slidably connected to the positioning rod 63, and the lifting seat 64 is connected to the housing dropping rod 411.

[0072] Through the above technical solution, the two positioning columns 61 and the positioning seats 62 form a frame and are fixed on the frame 1. The two positioning rods 63 are vertically arranged in the frame, one end is connected to the positioning seat 62, and the other end is connected to the frame 1. The position of the lifting seat 64 is stable during the lifting process, and further the position of the housing dropping rod 411 is stable during the lifting process, and can accurately lift the filter.

[0073] As a specific embodiment of the improvement, a feeding mechanism 7 is provided on the frame 1, and the feeding mechanism 7 includes:

[0074] A feeding chute 71, which is fixedly arranged on the frame 1, and a feeding chute 711 is provided on the feeding chute 71;

[0075] A feeding frame 72, which is fixedly arranged on the frame 1 and is connected to the feeding chute 71. When the housing dropping rod 411 is located below any one of the punching holes 111, the feeding frame 72 is located above the other punching hole 111;

[0076] A retaining edge 73, which is arranged on the upper side of the feeding frame 72;

[0077] A support rod 74, which is rotatably arranged on the lower side of the feeding frame 72, and the support rod 74 is interlocked with the housing push rod 412.

[0078] Through the above technical solution, the housing push rod 412 moves to push the trimmed filter housing into the external conveyor belt / external collection device. The movement of the housing push rod 412 drives the support rod 74 to move. The specific process is as follows: The first stage: The housing push rod 412 is pushed out to push the filter housing down; The second stage: The housing push rod 412 moves in the reverse direction to reset.

[0079] In the first stage, the housing push rod 412 drives the support rod 74 to rotate, so that the support rod 74 is gradually separated from the filter housing. When the support rod 74 is completely separated from the filter housing, the filter housing falls into the lower stamping die 112 under the action of gravity.

[0080] In the second stage, the housing push rod 412 moves in the reverse direction to reset, driving the support rod 74 to rotate in the reverse direction to reset. The support rod 74 flips and resets, and can support the next filter housing again.

[0081] The reciprocating movement of the housing push rod 412 simultaneously completes the feeding and discharging of the filter housing. The equipment control program is simple, with high stability, reduced drive structure, and more energy-saving.

[0082] The feeding chute 71 is inclined. The edge of the filter housing is located in the feeding chute 711, with stable position, and is transmitted one by one to avoid stacking. The transmission process is stable, and it slides downward under the action of gravity until it slides onto the feeding frame 72. The retaining edge 73 blocks the edge of the filter housing and restricts it in the feeding position, improving the stability during use. There is no need for manual feeding, with high precision and high stability.

[0083] As a specific improved embodiment, the support rod 74 is divided into a first rod 741 and a second rod 742. A connecting rod 75 is provided on the housing push rod 412. At the ends of the two connecting rods 75 away from the housing push rod 412, there is a side push rod 76. A second discharging rod 761 is provided on the side push rod 76. The second discharging rod 761 is rotatably connected to the second rod 742. A discharging space is formed between the connecting rod 75 and the side push rod 76. The connecting rod 75 is provided with a driving notch 751 and a supporting notch 752. The first rod 741 is located in the driving notch 751, and the second rod is located in the supporting notch 752. On the connecting rod 75 close to the feeding chute 71, there is a passing notch 77 for the filter housing to pass through.

[0084] Through the above technical solution, there are two first rods 741, which are arranged in a V shape, and two second rods 742, which are arranged in a V shape. The openings of the first rod 741 and the second rod 742 face each other. After the housing push rod 412 returns to its position, through the notch 77 corresponding to the moving path of the filter housing, it can move from the notch 77 to the loading frame 72. At this time, the first rod 741 and the second rod 742 support the filter housing. When the housing push rod 412 moves and causes the filter housing to fall, the process is as follows: The movement of the housing push rod 412 drives the connecting rod 75 to move. The movement of the connecting rod 75 drives the first rod 741 to rotate through the driving notch 751. At the same time, the movement of the connecting rod 75 drives the side push rod 76 to move, and then drives the second blanking rod 761 to move. The movement of the second blanking rod 761 drives the second rod 742 to rotate. The first rod 741 and the second rod 742 rotate simultaneously, causing the opening of the V shape to open until it is completely separated from the filter housing. At this time, the filter housing falls into the lower stamping hole 111 under the action of gravity. The four support rods 74 are separated from the filter at the same time, causing the filter housing to fall vertically and accurately fall into the stamping die 112.

[0085] Specifically, the upper end of the stamping die 112 has an inclined guiding portion, so that the falling filter can stably enter the stamping hole 111.

[0086] Moreover, as the housing push rod 412 moves, it is transferred through the notch 77 and is misaligned with the loading slideway 71. The connecting rod 75 blocks the filter housing in the loading slideway 71 from entering, so that the filter housings in the loading slideway 71 enter the loading frame 72 one by one, and then feeding is performed, with high stability.

[0087] After the blanking is completed, the housing push rod 412 moves in the reverse direction, and then drives the connecting rod 75 to move. The movement of the connecting rod 75 drives the first rod 741 to rotate in the reverse direction and return to its position through the driving notch 751. At the same time, the movement of the connecting rod 75 drives the side push rod 76 to move, and then drives the second blanking rod 761 to move. The movement of the second blanking rod 761 drives the second rod 742 to rotate in the reverse direction and return to its position; during the rotation and resetting process of the first rod 741 and the second rod 742, the notch 77 is continuously reset, and the notch 77 is reset simultaneously with the first rod 741 and the second rod 742. When the next filter passes through the notch 77, the first rod 741 and the second rod 742 have returned to the support position.

[0088] The above structure does not require electronic control and has high stability during use.

[0089] Specifically, a part of the second rod 742 is located in the support notch 752, so that the position stability of the second rod 742 is high and the stability is high when supporting the filter housing.

[0090] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
