DETAILED DESCRIPTION

[0016] The present invention will be further described below in detail with reference to the embodiments shown in the accompanying drawings.

[0017] Reference Figure 1 — Figure 8 As shown, the filter housing multi-station trimming machine of this embodiment includes: a frame 1 and a punching mechanism 2 arranged on the frame 1, the frame 1 is provided with a rotating disk 11, the rotating disk 11 is provided with a punching hole 111, the rotating disk 11 is provided with a punching die 112 outside the punching hole 111, the punching hole 111 is arranged circumferentially, the punching mechanism 2 is arranged above the punching hole 111, the rotating disk 11 rotates at intervals so that the punching holes 111 pass directly below the punching mechanism 2 in sequence, the punching mechanism 2 is provided with a cutting component 3, the cutting component 3 is used to cut off waste, the frame 1 is provided with a blanking device 4, the blanking device 4 includes a shell blanking mechanism 41 and a waste blanking mechanism 42, and the shell blanking mechanism 41 includes: The shell material discharge rod 411 is escalably arranged on the frame 1, and the shell material discharge rod 411 is arranged at the lower side of the rotating disk 11. When any punching hole 111 is located directly below the punching mechanism 2, the other punching hole 111 is located directly above the shell material discharge rod 411; The shell push rod 412 is horizontally slidably arranged on the frame 1, and the shell push rod 412 is located on the upper side of the rotating disk 11 and is adjacent to the shell unloading rod 411; The waste material unloading mechanism 42 includes: The cutting disc 421 is arranged outside the stamping die 112. The waste chute 422 is arranged on both sides of the cutting disc 421, and the waste chute 422 is arranged obliquely, gradually inclining downward from the inside to the outside; A waste collection frame 423 is arranged on one side of the frame 1 and below the rotating disk 11; The waste pushing plate 424 is movably arranged on the upper side of the cutting disk 421, and the waste pushing plate 424 is linked with the shell unloading rod 411.

[0018] Through the above technical solution, the punching holes 111 are arranged along the central circumference of the rotating disk 11, and the angle of one rotation of the rotating disk 11 is the central angle of the adjacent punching holes 111. When the equipment processes the filter housing, 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 loading equipment; the rotating disk 11 rotates, driving the punching holes 111 and the stamping die 112 to rotate, driving the stamping die 112 to pass through the stamping mechanism 2 in turn, and stay at this position, the stamping mechanism 2 and the cutting assembly 3 move in turn (the stamping mechanism 2 and the cutting mechanism move while the housing unloading mechanism 41 runs), completing the waste stamping of the filter housing and the cutting of the waste, and then the stamping mechanism 2 and the cutting assembly 3 are reset, and the rotating disk 11 rotates. Turn, move the next punching hole 111 to the lower side of the punching mechanism 2, and the punching hole 111 and the punching die 112 in front of the shell unloading mechanism 41 move to the position of the shell unloading mechanism 41, and the shell unloading mechanism 41 operates as follows: the shell unloading rod 411 rises, pushing the stamped filter shell above to rise, until the filter shell completely leaves the punching die 112, the shell pushing rod 412 moves, pushes the rising filter shell away from the punching die 112, falls to the side and pushes it into the external conveyor belt / external collection device; then the shell unloading rod 411 and the shell pushing rod 412 are reset, waiting for the next shell to be unloaded.

[0019] It should be noted that the cutting disc 421 cooperates with the cutting assembly 3 to cut the waste. When the housing push rod 412 rises, it drives the waste push plate 424 to rotate, so that the waste on the waste push disc falls into the waste slide 422, and then with the next rotation of the rotating frame, it is output to the waste collection frame 423.

[0020] The equipment can continuously process the filter housing during production, and collect the filter housing and waste materials while stamping. There is no need to manually collect waste materials or manually remove the stamped filter housing, and the efficiency is high.

[0021] As an improved specific implementation method, the cutting disk 421 is provided with a first through hole 51, the stamping die 112 is provided with a second through hole 52, and the rotating disk 11 is provided with a third through hole 53. 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 feed follower rod 54 is slidably connected in the first through hole 51. The upper end of the feed follower rod 54 passes through the first through hole 51 and is rotatably connected to the waste pushing plate 424. The feed follower rod 54 passes downward through the third through hole 53, and the side of the shell feed rod 411 is provided with a waste driving rod 55 extending vertically upward.

[0022] Through the above technical solution, the shell unloading rod 411 rises and drives the waste pushing plate 424 to move as follows: the shell unloading rod 411 rises, and then drives the waste driving rod 55 to rise, until the waste driving rod 55 conflicts with the unloading driven rod 54, and then the shell unloading rod 411 continues to rise and drives the unloading driven rod 54 to rise through the waste driving rod 55, and then drives the waste pushing plate 424 to rotate, pushing the waste on the waste pushing plate 424 into the waste chute 422. Then, it moves to the waste collection frame 423 through the waste chute 422.

[0023] When the shell material discharge rod 411 descends, it drives the waste driving rod 55 to descend, and at this time, the waste pushing plate 424 and the driven material discharge rod are reset under the action of gravity.

[0024] Specifically, a counterweight block 541 is provided at the lower end of the unloading driven rod 54. The contact area between the counterweight block 541 and the waste driving rod 55 is large, and the stability is high when driving the unloading driven rod 54. The counterweight at the lower end of the unloading driven rod 54 is increased to assist the unloading driven rod 54 to return to its original position quickly, thereby further improving production efficiency.

[0025] In addition, the counterweight block 541 limits the maximum rising distance of the unloading driven rod 54 (when rising to the highest position, the counterweight block 541 conflicts with the rotating disk 11), thereby improving stability during use.

[0026] As an improved specific implementation, a waste discharge notch 4211 is provided on the cutting disk 421, and the position of the waste discharge notch 4211 corresponds to the position of the waste pushing plate 424. The waste pushing plate 424 is arranged in an arc shape, and both sides of the waste pushing plate 424 are connected to the waste driving rod 55.

[0027] Through the above technical solution, the waste unloading notch 4211 is located on the rotation path of the waste pushing plate 424, so that when the unloading driven rod 54 rises to drive the waste pushing plate 424 to rotate, the rotation amplitude of the waste pushing plate 424 is large, and the waste can be pushed into the waste slide 422 faster and better, thereby improving stability during use.

[0028] The waste pushing plate 424 is arranged in an arc shape, which is similar to the shape of the waste, so that the waste pushing plate 424 can push the waste down more stably during rotation; both sides of the waste pushing plate 424 are connected to the waste driving rod 55, so that the position of the waste pushing plate 424 is stable during rotation.

[0029] As an improved specific implementation, the stamping mechanism 2 includes: The punching cylinder 21 is vertically fixed on the frame 1; The punching seat 22 is connected to the punching cylinder 21 and driven to rise and fall by the punching cylinder 21; The cutting component 3 includes: The cutting cylinder 31 is vertically fixed on the frame 1; A cutting sleeve 32 is arranged outside the punching seat 22 and is slidably connected to the punching seat 22. The cutting sleeve 32 is connected to the cutting cylinder 31 and is driven to rise and fall by the cutting cylinder 31. An upper cutting knife 33 is arranged on the lower side of the cutting sleeve 32. The cutting disc 421 is provided with a lower cutting knife 34 , and the movement path of the upper cutting knife 33 is adjacent to the lower cutting knife 34 . An auxiliary knife 35 is provided outside the stamping die 112 , and the position of the auxiliary knife 35 corresponds to that of the lower cutting knife 34 .

[0030] Through the above technical scheme, the operation process of the stamping mechanism 2 and the cutting mechanism is as follows: the operation of the stamping cylinder 21 drives the stamping seat 22 to descend, and the stamping seat 22 descends to cooperate with the stamping die 112 below to separate the filter housing and 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 component 3 operates, the cutting cylinder 31 drives the cutting sleeve 32 to descend, and 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 off the waste, and the auxiliary knife 35 cooperates with the upper cutting knife and the lower cutting knife to completely cut off the waste.

[0031] Specifically, there are two sets of upper cutting blades 33, lower cutting blades 34, and auxiliary blades 35, which are located on the radius of the rotating disk 11 to divide the waste into two equal parts. Then the waste pushing plate 424 moves to drive the two pieces of waste to fall onto the waste slide 422. With the next operation of the rotating disk 11, the centrifugal force generated causes the waste to fall into the waste collection frame 423. There is no need to set up an additional driving device to push the waste from the waste slide 422 into the waste collection frame 423, which reduces energy consumption and has high stability during use.

[0032] As an improved specific implementation, a pushing groove 4121 is provided on the shell pushing rod 412 , and a flexible gasket 4122 is provided in the pushing groove 4121 .

[0033] Through the above technical solution, when the shell pushing rod 412 moves to push the filter shell to be discharged, the filter shell is located in the pushing groove 4121 and is pushed down, so that the landing point of the filter shell is stable and accurate, which is convenient for collection. The flexible gasket 4122 conflicts with the filter shell during the pushing process to avoid wear on the filter surface.

[0034] As an improved specific implementation, two positioning columns 61 are provided on the frame 1, and a positioning seat 62 is provided on the positioning columns 61. A vertically arranged positioning rod 63 is provided between the two positioning columns 61, and a lifting seat 64 is slidably connected to the positioning rod 63, and the lifting seat 64 is connected to the shell unloading rod 411.

[0035] Through the above technical solution, two positioning columns 61 and the positioning seat 62 form a frame fixed on the frame 1, and 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 lifting seat 64 is stable in position during the lifting process, so that the shell unloading rod 411 is stable in position during the lifting process, and the filter can be accurately lifted.

[0036] As an improved specific implementation, the frame 1 is provided with a feeding mechanism 7, and the feeding mechanism 7 includes: A loading slide 71, wherein the loading slide 71 is fixedly arranged on the frame 1, and a loading chute 711 is provided on the loading slide 71; The loading frame 72 is fixedly arranged on the frame 1 and connected to the loading slideway 71. When the shell unloading rod 411 is located at the lower side of any punching hole 111, the loading frame 72 is located at the upper side of another punching hole 111; The stop edge 73 is arranged on the upper side of the loading frame 72; The support rod 74 is rotatably disposed on the lower side of the loading frame 72 , and the support rod 74 is linked to the shell pushing rod 412 .

[0037] Through the above technical solution, the shell push rod 412 moves to push the trimmed filter shell into the external conveyor belt / external collection device. The movement of the shell push rod 412 drives the support rod 74 to move, and the specific process is as follows: the first stage: the shell push rod 412 is pushed out to push the filter shell down; the second stage: the shell push rod 412 moves in the opposite direction to reset.

[0038] 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, until the support rod 74 is completely separated from the filter housing, and the filter housing falls into the stamping die 112 below under the action of gravity.

[0039] 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, and the support rod 74 flips over to reset, and can support the next filter housing again.

[0040] The housing push rod 412 reciprocates to simultaneously complete the loading and unloading of the filter housing. The equipment control program is simple, the stability is high, the driving structure is reduced, and it is more energy-efficient.

[0041] The feeding chute 71 is tilted, and the edge of the filter housing is located in the feeding chute 711, with a stable position, and the filter housing is transferred one by one to avoid stacking. The transfer process is stable, and the filter housing slides downward under the action of gravity until it reaches the feeding frame 72. The retaining edge 73 blocks the edge of the filter housing, limiting it in the feeding position, and improving the stability during use. No manual feeding is required, and the accuracy and stability are high.

[0042] As an improved specific implementation, the support rod 74 is divided into a first rod 741 and a second rod 742, and a connecting rod 75 is provided on the shell push rod 412. A side push rod 76 is provided at one end of the two connecting rods 75 away from the shell push rod 412, and a second unloading rod 761 is provided on the side push rod 76. The second unloading rod 761 is rotatably connected to the second rod 742, and a unloading space is formed between the connecting rod 75 and the side push rod 76. A driving notch 751 and a supporting notch 752 are provided on the connecting rod 75. The first rod 741 is located in the driving notch 751, and the second rod is located in the supporting notch 752. The connecting rod 75 close to the side of the loading slide 71 has a passing notch 77 for the filter housing to pass through.

[0043] Through the above technical solution, the first rod 741 has two V-shaped arrangements, the second rod 742 has two V-shaped arrangements, the openings of the first rod 741 and the second rod 742 are arranged facing each other, and after the shell push rod 412 returns to its position, the notch 77 corresponds to the moving path of the filter shell, and 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 shell. When the housing push rod 412 moves and the filter housing falls, the process is as follows: the housing push rod 412 moves and drives the connecting rod 75 to move, and the connecting rod 75 drives the first rod 741 to rotate through the driving notch 751. At the same time, the connecting rod 75 drives the side push rod 76 to move, and then drives the second material discharge rod 761 to move, and the second material discharge rod 761 drives the second rod 742 to rotate, and the first rod 741 and the second rod 742 rotate at the same time, so that the V-shaped opening opens until it is completely separated from the filter housing. At this time, the filter housing falls into the stamping hole 111 below under the action of gravity. The four support rods 74 are separated from the filter at the same time, so that the filter housing falls vertically and falls accurately into the stamping die 112.

[0044] Specifically, the upper end of the stamping die 112 has an inclined guide portion so that the dropped filter can stably enter the stamping hole 111 .

[0045] Moreover, as the shell push rod 412 moves, it is transferred through the notch 77 and misaligned with the loading chute 71. The connecting rod 75 blocks the filter shell in the loading chute 71 from entering, so that the filter shells in the loading chute 71 enter the loading frame 72 one by one, and then loading is carried out, with high stability.

[0046] After the unloading is completed, the shell push rod 412 moves in the opposite direction, thereby driving the connecting rod 75 to move. The movement of the connecting rod 75 drives the first rod 741 to rotate and reset in the opposite direction through the driving notch 751. At the same time, the movement of the connecting rod 75 drives the side push rod 76 to move, thereby driving the second unloading rod 761 to move. The movement of the second unloading rod 761 drives the second rod 742 to rotate and reset in the opposite direction. During the rotation and reset process of the first rod 741 and the second rod 742, they are continuously reset through the notch 77, and are reset at the same time as the first rod 741 and the second rod 742 through the notch 77. When the next filter passes through the notch 77, the first rod 741 and the second rod 742 have returned to the supporting position.

[0047] The above structure does not require electronic control and has high stability during use.

[0048] Specifically, 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 when supporting the filter housing is high.

[0049] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
