The brewing head is mainly composed of a handle seal, a filter, an outer clamping ring for fixing the filter, and an inner filter cover. The filter is an important component for coffee filtration. At present, the filter of most brewing heads is made of metal. The mesh of the filter woven from metal is easily affected by the processing process.

[0018] Example, see Figures 1 to 7 A molding device for manufacturing a coffee machine, comprising a molding table 1 for molding a brewing head, the molding table 1 is connected to a station conversion disk 3 through L-shaped brackets 2 on both sides, a conversion motor 4 is arranged on the station conversion disk 3, the conversion motor 4 is connected to a rotating disk 5, a centrifugal equalizing component and a feeding pressing component are alternately arranged on the rotating disk 5, and the rotating disk 5 is rotated by the setting of the conversion motor 4, so that the centrifugal equalizing component and the feeding pressing component are switched in position; Furthermore, the centrifugal equalizing member includes a centrifugal following disk 17 rotatably arranged on the telescopic outer cylinder 13, and a resistance ball 18 is arranged at the center of the base seat 6. The curvature of the resistance ball 18 should not be too large. A resistance port adapted to the resistance ball 18 is opened on the centrifugal following disk 17, and a plurality of magnetic control grooves 19 with gradually increasing inner diameters are arranged in the centrifugal following disk 17. Power is gradually supplied to the magnetic control grooves 19 from the inside to the outside, so that the gradual pressure ring 20 arranged in the magnetic control grooves 19 squeezes the metal filter outward to ensure that the evenly distributed filter eyes will not reset when closed and rotated, and the pressing and shaping effect can be achieved synchronously. The inner wall of the magnetic control groove 19 is connected to the gradual pressure ring 20 through a plurality of connecting springs. The feeding pressing member includes an extrusion die sleeve 21 fixedly arranged on the telescopic outer cylinder 13, and a magnetic pressure port 22 is arranged in the extrusion die sleeve 21. The magnetic pressure port 22 itself is made of magnetic metal material, and the magnetic force of the magnetic pressure port 22 is used to effectively adsorb and fix the inner metal filter cover.

[0019] The centrifugal equalizing part and the feeding pressing part are connected to the rotating disk 5 through the abutting pressing connecting part, which includes a telescopic outer cylinder 13 and a fixed inner shaft 14. The fixed inner shaft 14 is connected to the telescopic outer cylinder 13 through a reset sleeve spring. It is a conventional structural design and will not be described in detail here. The fixed inner shaft 14 is fixedly arranged on the rotating disk 5. A pressure feeding push rod 15 is arranged on the L-shaped bracket 2, and a multi-fold pressing plate 16 is fixedly connected to the bottom of the pressure feeding push rod 15. The arrangement of the multi-fold pressing plate 16 does not affect the switching of the centrifugal equalizing part and the feeding pressing part. The multi-fold pressing plate 16 will drive the telescopic outer cylinder 13 to move downward, thereby moving the telescopic outer cylinder 13 downward to be sleeved in the outer positioning ring disk 9 to perform the forming process of the brewing head component.

[0020] A base seat 6 is rotatably arranged on the processing and forming table 1, and an annular groove 7 is provided in the base seat 6. A forming die ring driven by a hydraulic push rod is provided in the annular groove 7. Further, the forming die ring includes an outer cover positioning ring 23 and an extrusion die body 24 arranged in the outer cover positioning ring 23. The outer cover positioning ring 23 and the extrusion die body 24 are connected by a pressure spring. An annular chamber is provided in the base seat 6. The hydraulic push rod is arranged in the processing and forming table 1, and its output end passes through the annular chamber and is rotatably connected with a pressure plate 25. The rotatable connection does not affect the rotation of the base seat 6. The pressure plate 25 is connected to the extrusion die body 24 through a pressure column 26. A plurality of pressure columns 26 sequentially pass through the base seat 6 and the outer cover positioning ring 23 and extend upward.

[0021] It should be noted that the extrusion die body 24 is designed as a V-shaped structure, which is designed for the pressing of the metal filter screen and the outer clamping ring. When pressure is applied, the edge of the metal filter cover and the outer clamping ring can be pressed and fixed, which is a conventional design of the die.

[0022] A rotating motor 8 is arranged on the processing and forming table 1, and the rotating motor 8 is connected to the base seat 6 through a joint control rotating member. The joint control rotating member includes a rotating gear disk fixedly arranged on the outer wall of the base seat 6, and the output end of the rotating motor 8 is fixedly connected to a rotating gear meshing with the rotating gear disk.

[0023] An outer positioning ring disk 9 is arranged above the processing and forming table 1, and the outer positioning ring disk 9 is connected to a movable fastening ring disk 10 through an electromagnetic spring component. The electromagnetic spring component includes an L-shaped support plate 27 arranged on both sides of the outer positioning ring disk 9, and an electromagnetic seat 28 is arranged on the L-shaped support plate 27. The L-shaped support plate 27 is slidably connected to a contact plate 30 connected to the movable fastening ring disk 10 through a slide groove component 29. The contact plate 30 is connected to the L-shaped support plate 27 through a return spring, and a magnetic suction block that is magnetically attracted to the electromagnetic seat 28 is arranged on the contact plate 30.

[0024] The inner wall of the outer positioning ring disk 9 is fixedly connected with an inclined inner ring 11, and the inner wall of the movable fastening ring disk 10 is provided with an inclined outer ring 12 adapted to the inclined inner ring 11. The electromagnetic seat 28 is controlled to supply power so that the resistance plate 30 is close to the L-shaped support plate 27 under the action of magnetic force, so that the inclined outer ring 12 originally under the metal filter moves upward, squeezes the metal filter, and fastens the metal filter through the joint action of the inclined inner ring 11.

[0025] When the coffee machine brewing head is formed and processed, the metal filter screen, the outer clamp ring and the inner metal filter cover constituting the brewing head are first loaded, the outer ring is placed on the extrusion die body 24 in the annular groove 7 on the base seat 6, and the inner metal filter screen cover is placed in the magnetic pressure port 22 in the extrusion die sleeve 21. The magnetic force of the magnetic pressure port 22 is used to effectively adsorb and fix the inner metal filter screen cover, and the metal filter screen is placed on the base seat 6 to complete the loading process. The station conversion disk 3 is switched by the conversion motor 4, so that the centrifugal follower disk 17 moves downward. At this time, the pressure delivery push rod 15 located on the L-shaped bracket 2 is controlled to drive and drive the multi-fold pressure plate 16 to move downward. The downward movement of the multi-fold pressure plate 16 will squeeze the telescopic outer cylinder 13 carrying the centrifugal follower disk 17 to move downward, so that the centrifugal follower disk 17 passes through the outer positioning ring disk 9, moves downward, and contacts with the metal filter screen on the base seat 6. Under the action of the resistance ball 18, the metal filter screen is tightened. At this time, the rotation motor is controlled 8 drives the base seat 6 to rotate, thereby generating an outward centrifugal force on the metal filter screen, flattening the metal filter screen under the action of the centrifugal force, and generating a uniform centripetal pulling force from the inside to the outside, thereby ensuring that the filter mesh on the metal filter screen is evenly distributed under the action of the centrifugal force. At this time, the magnetron slot 19 is gradually powered from the inside to the outside, so that the gradually pressing ring 20 set in the magnetron slot 19 squeezes the metal filter screen outward, ensuring that the evenly distributed filter mesh will not reset when it is closed and rotated, and can simultaneously achieve the effect of pressing and shaping; After the metal filter is squeezed, the electromagnetic seat 28 is controlled to supply power, so that the contact plate 30 is moved close to the L-shaped support plate 27 under the action of magnetic force, so that the inclined outer ring 12 originally under the metal filter moves upward, squeezing the metal filter, and the inclined inner ring 11 works together to ensure the state of the metal filter after shaping; The control conversion motor 4 is switched, and the extrusion die sleeve 21 drives the inner metal filter cover located in the magnetic pressure port 22 to move downward, and penetrates the outer positioning ring plate 9 to move downward, and contacts and fits tightly with the metal filter screen that is tightly fixed by the inclined outer ring 12 and the inclined inner ring 11. At this time, the hydraulic push rod in the base seat 6 is opened to drive the extrusion die body 24 to move upward, and the outer clamping ring in the extrusion die body 24 is pressed together with the metal filter cover. Under the die-forming cooperation of the extrusion die body 24, the metal filter cover and the outer clamping ring, the metal filter screen in a tight state can be effectively locked, thereby completing the combined molding process of the brewing head.
