Description

Technical Field

[0002] The brewing head of a coffee machine is a core component that directly affects the extraction effect of coffee and the performance of the machine. The brewing head mainly consists of a handle seal, a filter screen, an outer snap ring for fixing the filter screen, and an inner filter cover. The filter screen is an important component for coffee filtration. Currently, most filter screens of brewing heads are made of metal. The filter screen woven from metal has its mesh holes easily affected by the processing process, and the unevenly distributed mesh holes and wrinkles will affect the filtration uniformity. When the tight pressure of the outer snap ring and the inner filter cover on the filter screen is insufficient during the assembly process, the filter screen cannot be tightly attached to the filter cover, resulting in the situation that when the filter screen filters coffee, the coffee is concentrated in the liquid outlet, the coffee powder is unevenly distributed on the filter screen, affecting the liquid outlet effect and efficiency. This makes it necessary to ensure the state of the filter screen during the molding process of the brewing head to ensure that the filter screen and the filter screen cover are tightly attached after combination. Currently, the processing method mainly relies on manual combination, which cannot guarantee the molding quality. Based on this, a molding device for manufacturing coffee machines is proposed.

Detailed implementation manner

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "provided with", "sleeved / connected", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] Embodiment, refer to Figures 1 to 7 , a forming device for manufacturing a coffee machine, including a processing and forming table 1 for forming a brewing head. The processing and forming table 1 is commonly connected with 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 with a rotating disk 5. Centrifugal equalizing parts and feeding and pressing parts are arranged at intervals on the rotating disk 5. Through the arrangement of the conversion motor 4, the rotating disk 5 is rotated, so as to switch the working positions of the centrifugal equalizing parts and the feeding and pressing parts;

[0030] Further, the centrifugal equalizing member includes a centrifugal follower disk 17 rotatably arranged on the telescopic outer cylinder 13. A contact ball 18 is arranged at the center of the base seat 6. The radian of the contact ball 18 should not be too large. A contact opening adapted to the contact ball 18 is formed on the centrifugal follower disk 17. A plurality of magnetically controlled grooves 19 with gradually increasing inner diameters are arranged in the centrifugal follower disk 17. Power is supplied to the magnetically controlled grooves 19 gradually from the inside to the outside, so that the gradually pressing ring 20 arranged in the magnetically controlled grooves 19 presses the metal filter net outward, ensuring that the evenly distributed filter holes will not reset when the rotation is closed and can achieve the effect of synchronous pressing and shaping at the same time. The inner wall of the magnetically controlled groove 19 is connected with the gradually pressing 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. A magnetic pressing opening 22 is arranged in the extrusion die sleeve 21. The magnetic pressing opening 22 is made of magnetic metal material, and the effective adsorption and fixation of the inner metal filter cover is realized through the magnetic force of the magnetic pressing opening 22.

[0031] Both the centrifugal equalizing member and the feeding pressing member are connected to the rotating disk 5 through a contact pressing connecting member. The contact pressing connecting member includes a telescopic outer cylinder 13 and a fixed inner shaft 14. The fixed inner shaft 14 and the telescopic outer cylinder 13 are connected through a reset sleeve spring, which is a conventional structural design and will not be elaborated here. The fixed inner shaft 14 is fixedly arranged on the rotating disk 5;

[0032] A feeding pressing push rod 15 is arranged on the L-shaped bracket 2. The bottom of the feeding pressing push rod 15 is fixedly connected with a multi-fold pressing plate 16. The setting of the multi-fold pressing plate 16 does not affect the switching between the centrifugal equalizing member and the feeding pressing member. When the multi-fold pressing plate 16 moves downward, it will drive the telescopic outer cylinder 13 to move downward, so as to sleeved the telescopic outer cylinder 13 downward into the outer positioning ring plate 9 for the forming processing of the brewing head component.

[0033] A base seat 6 is rotatably arranged on the processing and forming table 1. An annular groove 7 is formed in the base seat 6. An forming die ring driven by a hydraulic push rod is arranged 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 through a pressure spring. An annular chamber is formed in the base seat 6. The hydraulic push rod is arranged in the processing and forming table 1, and its output end penetrates into the annular chamber and is rotatably connected with a pressing disk 25. Among them, the rotatable connection setting does not affect the rotation of the base seat 6. The pressing disk 25 is connected with the extrusion die body 24 through a pressing column 26. A plurality of pressing columns 26 sequentially penetrate through the base seat 6 and the outer cover positioning ring 23 and extend upward.

[0034] It should be noted that the extrusion die body 24 is designed in a V-shaped structure and is designed for the pressing of the metal filter net and the outer clamping ring. It can achieve the effect of pressing and fixing the edge of the inner metal filter cover and the outer clamping ring during pressing, which is a conventional design of the pressing die.

[0035] A rotating motor 8 is arranged on the processing and forming table 1. The rotating motor 8 is connected to the base 6 through a linkage rotating member. The linkage rotating member includes a rotating gear disc fixedly arranged on the outer side wall of the base 6, and the output end of the rotating motor 8 is fixedly connected with a rotating gear meshed with the rotating gear disc.

[0036] An outer positioning ring plate 9 is arranged above the processing and forming table 1. The outer positioning ring plate 9 is connected with a moving fastening ring plate 10 through an electromagnetic spring member. The electromagnetic spring member includes L-shaped support plates 27 arranged on both sides of the outer positioning ring plate 9. An electromagnetic seat 28 is arranged on the L-shaped support plate 27. The L-shaped support plate 27 is slidably connected with a contact plate 30 connected to the moving fastening ring plate 10 through a chute member 29. The contact plate 30 is connected with the L-shaped support plate 27 through a return spring. A magnetic attraction block magnetically attracted to the electromagnetic seat 28 is arranged on the contact plate 30.

[0037] The inner wall of the outer positioning ring plate 9 is fixedly connected with an inclined inner ring 11, and the inner wall of the moving fastening ring plate 10 is provided with an inclined outer ring 12 adapted to the inclined inner ring 11. The electromagnetic seat 28 is powered on, so that the contact plate 30 approaches the L-shaped support plate 27 under the action of magnetic force, so that the inclined outer ring 12 originally located below the metal filter screen moves upward, extrudes the metal filter screen, and jointly acts with the inclined inner ring 11 to fasten the metal filter screen.

[0038] When the present invention forms and processes the coffee machine brewing head, first, the metal filter screen, the outer clamping ring, and the inner metal filter cover forming the brewing head are loaded. The outer clamping ring is placed on the extrusion die body 24 in the annular groove 7 on the base 6, and the inner metal filter cover is placed in the magnetic pressing port 22 in the extrusion die sleeve 21. The effective adsorption and fixation of the inner metal filter cover are realized through the magnetic force of the magnetic pressing port 22. The metal filter screen is placed on the base 6 to complete the loading process;

[0039] 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;

[0040] 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;

[0041] The control conversion motor 4 is switched to drive the extrusion die sleeve 21 to move the inner metal filter cover in the magnetic pressure port 22 downward, and pass through the outer positioning ring plate 9 to move downward, and contact and fit 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 inner metal filter cover. With the die-forming cooperation of the extrusion die body 24, the inner 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.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
