It should be noted that the following are only some specific embodiments of the present utility model, and the specific direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model. Conventional choices and substitutions made by those skilled in the art under the guidance of the present utility model concept should all be considered within the scope of protection claimed by this utility model.

[0059] like Figures 1-13 As shown, this utility model discloses an automated production device for a filter element used in cup lids, comprising:

[0060] The frame 1 has a hole-opening station 12, an ultrasonic welding station 13 and an ultrasonic cutting station 14 arranged sequentially to the right.

[0062] Ultrasonic welding device 4 is installed at ultrasonic welding station 13.

[0063] Ultrasonic cutting device 5 is installed at ultrasonic cutting station 14.

[0064] Therefore, the first material strip 91 used to process and form the plastic ring 941 can be conveyed from left to right, and when passing through the punching device 3, the lower part of the waste material on the first material strip 91 is punched to form the inner hole 9411. Then, the first material strip 91 is stacked on top and the second material strip 92 is stacked on the bottom and passed through the ultrasonic welding device 4. The ultrasonic welding device 4 ultrasonically welds the stacked first material strip 91 and the second material strip 92 around the inner hole 9411 to form a welding area 943. Then, it passes through the ultrasonic cutting device 5. The ultrasonic cutting device 5 is used to ultrasonically cut the stacked first material strip 91 and the second material strip 92 around the welding area 943 to form a filter element 94 that is separated from the first material strip 91 and the second material strip 92. The formed filter element 94 is formed by combining the upper plastic ring 941 and the lower filter screen 942, and the two are ultrasonically welded to ensure the stability of the connection. Thus, the filter element 94 is produced automatically to improve the production efficiency of the filter element 94 and the quality stability of the product.

[0065] The frame 1 is located to the left of the opening station 12 and has a feeding station 11. The feeding station 11 is provided with a first feeding structure 21 and a second feeding structure 22. Specifically, the first feeding structure 21 includes a first winding roller 211 for winding a first strip 91 and a plurality of first guide rollers 212 for guiding and transmitting the first strip 91 on the first winding roller 211 to the punching device 3. The second feeding structure 22 includes a second winding roller 221 for winding a second strip 92 and a plurality of second guide rollers 222 for guiding and transmitting the second strip 92 on the second winding roller 221 to the ultrasonic welding device 4. The first winding roller 211 is located above and behind the second winding roller 221.

[0066] Specifically, the blanking device 3 includes an upper die 31, a lower die 32, and a blanking cylinder 33. The lower die 32 is provided with a vertically penetrating blanking channel 321, and the upper die 31 is provided with a downwardly protruding blanking die head 311. The blanking cylinder 33 is fixedly installed above the upper die 31, and the upper die 31 is fixedly installed at the lower end of the output shaft of the blanking cylinder 33, so that the blanking cylinder 33 is used to drive the upper die 31 to move vertically so that the blanking die head 311 is punched into the blanking channel 321 or pulled out from the blanking channel 321, thereby completing the blanking of the inner hole 9411.

[0067] Specifically, the ultrasonic welding device 4 includes a first ultrasonic vibrating head 41, a welding mold head 42, a first cylinder 43, and a second cylinder 44. The first ultrasonic vibrating head 41 is located below, and the welding mold head 42 is located above, so that the first ultrasonic vibrating head 41 and the welding mold head 42 are arranged vertically opposite each other. The first cylinder 43 is fixedly installed below the first ultrasonic vibrating head 41, and the output shaft of the first cylinder 43 faces upward and is fixedly installed with the first ultrasonic vibrating head 41, so that the first cylinder 43 can drive the first ultrasonic vibrating head 41 to move up and down to approach or move away from the welding mold head 42. The output shaft of the second cylinder 44 faces downward and is fixedly installed with the welding mold head 42, so that the second cylinder 44 can drive the welding mold head 42 to move up and down to approach or move away from the first ultrasonic vibrating head 41.

[0068] The top of the first ultrasonic vibrating head 41 is flat, and the bottom of the welding mold head 42 is adapted to the shape of the plastic ring 941.

[0069] Therefore, after the first material strip 91 and the second material strip 92 are delivered to their positions, the first cylinder 43 and the second cylinder 44 operate respectively to clamp the first material strip 91 and the second material strip 92 between the first ultrasonic vibrating head 41 and the welding mold head 42. Then, the first ultrasonic vibrating head 41 vibrates at a high frequency under the action of the ultrasonic generator, thereby ultrasonically welding the first material strip 91 and the second material strip 92 at the intersection to form a welding area 943, and the shape of the welding area 943 corresponds to the bottom of the welding mold head 42.

[0070] Specifically, the ultrasonic cutting device 5 includes a second ultrasonic vibrating head 51, a cutting mold head 52, a third cylinder 53, and a fourth cylinder 54. The second ultrasonic vibrating head 51 is located below and the cutting mold head 52 is located above, so that the second ultrasonic vibrating head 51 and the cutting mold head 52 are arranged vertically opposite each other. The third cylinder 53 is fixedly installed below the second ultrasonic vibrating head 51, and the output shaft of the third cylinder 53 faces upward and is fixedly installed with the second ultrasonic vibrating head 51, so that the third cylinder 53 can drive the second ultrasonic vibrating head 51 to move up and down to approach or move away from the cutting mold head 52. The output shaft of the fourth cylinder 54 faces downward and is fixedly installed with the cutting mold head 52, so that the fourth cylinder 54 can drive the cutting mold head 52 to move up and down to approach or move away from the second ultrasonic vibrating head 51.

[0071] The top of the second ultrasonic vibrating head 51 is flat, and the bottom of the cutting mold head 52 is provided with a cutting ring blade 525 that is adapted to the outer circumferential shape of the plastic ring 941.

[0072] Therefore, after the first material belt 91 and the second material belt 92 are delivered to their positions, the third cylinder 53 and the fourth cylinder 54 operate respectively to make the second ultrasonic vibrating head 51 and the cutting die head 52 clamp the first material belt 91 and the second material belt 92 from above and below. Then, the second ultrasonic vibrating head 51 vibrates at high frequency under the action of the ultrasonic generator, thereby cutting the filter element 94 on the first material belt 91 and the second material belt 92 under the action of the cutting ring blade 525.

[0073] In this embodiment, the combination of the first ultrasonic vibrating head 41 and the second ultrasonic vibrating head 51 with the ultrasonic generator adopts a 15K matching machine.

[0074] In addition, the frame 1 is provided with a feeding station 16 and a transmission device 7 for transferring the filter element 94 from the ultrasonic cutting station 14 to the feeding station 16.

[0075] Specifically, the transmission device 7 includes a sliding frame 71, a sliding seat 72, and a sliding drive device 73. The track direction of the sliding frame 71 is along the front-back direction. The sliding seat 72 is slidably mounted on the sliding frame 71. The sliding drive device 73 is used to drive the sliding seat 72 to slide. The top of the fourth cylinder 54 is fixedly mounted on the sliding seat 72.

[0076] In this embodiment, the sliding drive device 73 uses a motor, a lead screw, and a nut. Other embodiments may use a combination of a motor, a synchronous pulley, and a synchronous belt.

[0077] The unloading station 16 is equipped with a receiving turntable 81 and a rotation drive device 82. The rotation drive device 82 is used to drive the receiving turntable 81 to rotate. The rotation axis of the receiving turntable 81 is vertical. Four receiving seats 811 are arranged circumferentially on the upper side of the receiving turntable 81. The receiving seats 811 are provided with placement grooves 812 that are adapted to the shape and size of the filter element 94 on the upper side. A transfer position 161 is provided on the left side of the unloading station 16. The transfer position 161 is located on the movement trajectory of each receiving seat 811. In addition, an alignment frame 813 is provided on the upper side of the receiving seat 811. The alignment frame 813 has a U-shaped structure so that the alignment frame 813 forms an alignment opening 8131. When the receiving seat 811 is located at the transfer position 161, the alignment opening 8131 is facing forward.

[0078] The rotation drive device 82 can be a servo motor that directly drives the receiving turntable 81 to rotate, or it can be a servo motor combined with a reduction gearbox or other reduction device to drive the receiving turntable 81 to rotate.

[0079] The cutting die head 52 is provided with four push channels 521 and an air supply channel 522. The push channels 521 are arranged in a matrix, and each push channel 521 includes a larger diameter first channel 5211 at the top and a smaller diameter second channel 5212 at the bottom. The second channel 5212 extends downward to the bottom of the cutting die head 52. Each push channel 521 is provided with a push rod 5213. The diameter of the push rod 5213 is adapted to the diameter of the second channel 5212. The push rod 5213 forms a piston portion 5214 in the first channel 5211 that is adapted to the diameter of the first channel 5211. In addition, the first channel 5211 extends upward to the bottom of the cutting die head 52. The top of the cutting die head 52 is provided with an air supply channel 522 to connect each of the first channels 5211. In addition, the air supply channel 522 also has an air inlet 5221 on the right side surface of the cutting die head 52 to connect the air inlet 5221 to the air source. A solenoid valve is used to control whether the air source supplies air to the air inlet 5221. When the air source supplies air to the air inlet 5221, the upper part of each piston part 5214 is pressurized and drives the push rod 5213 to extend downward from the cutting die head 52. The solenoid valve cuts off the air supply and connects the air inlet 5221 to the outside atmosphere, so that the push rod 5213 can move up and down arbitrarily.

[0080] The cutting die head 52 is provided with four negative pressure channels 523 and an air extraction channel 524. The negative pressure channels 523 are arranged in a matrix and each negative pressure channel 523 extends downward to the bottom of the cutting die head 52. The air extraction channel 524 is arranged in a cross shape so that the air extraction channel 524 and each negative pressure channel 523 are connected. The air extraction channel 524 also has an air extraction port 5241 on the left side surface and / or the front and rear side surfaces of the cutting die head 52, so that the air extraction port 5241 is connected to the air extraction device, so that the air extraction device works and the negative pressure channel 523 generates suction at the bottom of the cutting die head 52.

[0081] Among them, each push channel 521 and negative pressure channel 523 is located on the inner circumference of the cutting ring blade 525.

[0082] Therefore, after the ultrasonic cutting device 5 cuts the filter element 94, the suction device works to adsorb the filter element 94 onto the bottom of the cutting mold head 52. Then, the fourth cylinder 54 works to drive the cutting mold head 52 upward, so that the filter element 94 and the first material belt 91 and the second material belt 92 are misaligned. Then, the sliding drive device 73 works to move the sliding seat 72 backward, so as to bring the filter element 94 to the top of the placement groove 812. The accuracy of the alignment is ensured by the cooperation of the cutting mold head 52 and the alignment frame 813. Finally, by stopping the work of the suction device and venting the air supply channel 522 through the air source, the push rod 5213 extends downward to push the filter element 94 into the placement groove 812. Subsequently, the rotation of the receiving turntable 81 can be realized in a non-interference state by rotating the drive device 82 to transfer the filter element 94 at the transfer position 161 to other positions for unloading.

[0083] In addition, a power station 15 is provided on the right side of the ultrasonic cutting station 14 of the frame 1; wherein, the power station 15 is provided with a first pressure roller 61, a second pressure roller 62 and a power motor 63. The first pressure roller 61 and the second pressure roller 62 are both rotatably arranged relative to the frame 1, and the axis of rotation is along the front-back direction. The power motor 63 adopts a combination of a servo motor and a reducer, and drives the first pressure roller 61 to rotate. The overlapping first material strip 91 and second material strip 92 are output to the right by the action of the rotating first pressure roller 61 and the second pressure roller 62 between the first pressure roller 61 and the second pressure roller 62.

[0084] In this embodiment, the first direction is defined as the left-right direction, and the second direction is the front-back direction.
