Description

Technical Field

[0001] The present invention relates to the technical field of suspended conveying, and more particularly to a layered suspended conveying structure of a coffee powder box of a coffee machine. Background Art

[0002] In the process of the intelligent hanging conveying system of the coffee machine, the layered hanging conveying mechanism of the coffee machine's coffee powder box plays an important role. Its core function is to accurately convey the ingredient powder in the coffee machine's coffee powder box to the designated discharge port in a hanging manner, so as to meet the demand for intelligent delivery of different ingredient powders in the coffee making process.

[0003] Among the existing technical literature, Chinese Patent Publication No. CN211945429U discloses a layered structure for a coffee machine's coffee powder cartridge. This technology utilizes a central divider that divides the cartridge into two upper and lower chambers. This divider features a feed opening and includes a movable baffle mechanism for opening and closing the feed opening. This layered structure is simple and easy to use, effectively preventing material deterioration and moisture, as well as problems such as lumping and poor discharge caused by compression at the bottom. However, this patent presents the following issues.

[0004] Although the coffee powder box of the coffee machine has the function of conveying coffee powder raw materials in layers, it has obvious disadvantages when conveying coffee powder of different types of ingredients. It is necessary to open the conveying port of the coffee powder box one by one to convey the coffee powder, and each type of coffee powder must be individually controlled for conveying and discharging. This makes it difficult to realize the synchronous conveying and discharging of multiple types of coffee powder according to different ingredients, making the hanging conveying and discharging efficiency low. At the same time, since each coffee powder box requires an individual control switch for conveying and discharging, the complexity of the conveying system is increased. Once a fault occurs, the difficulty of maintenance increases and each part requires electric control switch for conveying, and the cost of use and maintenance also increases accordingly. For this reason, a layered hanging conveying structure of the coffee powder box of the coffee machine is needed. Summary of the Invention

[0012] The technical effects and advantages of the present invention are as follows: 1. The present invention adopts a layered synchronous switching conveying component. When four materials are switched and conveyed synchronously, the wireless controller starts the micro-electric cylinder to move the connecting block frame downward, so that the frame drives multiple linkage blocks and multiple switching sealing plates to move downward synchronously. When the distance sensor detects that the distance change of the sensing block is exactly thirty centimeters, the micro-electric cylinder is closed to achieve the docking of the conveying upper hole and the conveying pipe, and the hanging sealing plate blocks the conveying pipe, so that the four types of coffee powder materials are synchronously suspended and conveyed into the collection cover for downward conveying.

The power source of the same micro-electric cylinder is used to realize the intelligent suspension and synchronous conveying of multiple coffee powders. At the same time, multiple upper conveying boxes and multiple lower conveying boxes realize upper and lower layer processing, so that eight kinds of coffee powders are synchronously conveyed to the collection cover. This design avoids the tediousness of controlling the delivery of coffee powders one by one, greatly improves the efficiency of synchronous unloading of eight kinds of coffee powders, and reduces the control components of multiple independent conveying switches, reduces energy consumption and failure risks during use, and effectively reduces use and maintenance costs.

[0014] 3.

[0029] In this embodiment, if Figure 4 - Figure 6As shown, the outer wall of the suspension rope 10 is slidably connected with a sleeve 18; the sleeve 18 is fixedly connected to the feed pipe 17, and a positioning column 19 is slidably connected to the inner wall of the suspension rope 10 near the position of the suspension cover plate 11.

The sensing block 24 is fixedly connected to the frame bar 4. The wireless controller 25 is fixed on the other side of the outer wall of the micro-electric cylinder 2. The distance sensor 23 and the wireless controller 25 are electrically connected so that the connecting block 3 drives the sensing block 24 to move downward, and the sensing block 24 moves away from the distance sensor 23. When the distance change value between the sensing block 24 and the distance sensor 23 is a positive value of thirty centimeters, the micro-electric cylinder 2 is turned off by the wireless controller 25, thereby realizing intelligent positioning of the moving position of the connecting block 3.

[0031] In this embodiment, if Figure 1 - Figure 9 As shown, the other side of each switching sealing plate 6 is fixedly connected to a limit cover 26, and an inclined plate 27 is installed on the inner wall of the limit cover 26, and the vertical cross-section of the inclined plate 27 is triangular, so that the four coffee powders, vanilla powder, cocoa powder, and cinnamon powder can all enter the inclined plates 27 on the multiple limit covers 26 to achieve the guidance and discharge operation. The inclined plate 27 can achieve inclined guidance and guide the coffee powder material to the inner wall of the collection cover 29 for the guidance and discharge operation. A delivery valve 28 is fixedly connected to the bottom end of one of the delivery pipes 9 so that when a single flavor is required for delivery and discharge, the delivery valve 28 is opened, so that one of the delivery upper boxes 1 containing coffee powder can deliver the coffee powder into the delivery pipe 9, and then deliver it to the delivery valve 28 through the delivery pipe 9, and the delivery valve 28 can realize the delivery and discharge operation.

[0032] In this embodiment, if Figure 1As shown, the top of the upper conveying box 1 is threadedly connected to a top cover 31, and a collection cover 29 is fixedly connected to the outer wall of the upper conveying box 1 near the top cover 31. A hanger 32 is provided in the gap surrounded by the multiple top covers 31, and the hanger 32 is fixedly connected to the upper conveying box 1. The inner wall of the collection cover 29 is smooth, and a cavity is opened inside the collection cover 29 to facilitate the installation of the hanger 32 on the internal suspension of the commercial coffee machine. Bolts are inserted into the holes of the hanger 32, and the hanger 32 and the internal suspension of the commercial coffee machine are bolted together. The bottom end of the collection cover 29 is docked with the hopper of the commercial coffee machine for making coffee. The multiple top covers 31 are rotated forward to separate and open the upper conveying box 1, and the four types of coffee powder are poured into the multiple upper conveying boxes 1 for storage, making it easy to install and use.

[0033] The working principle of the layered suspension conveying structure of the coffee powder box of the coffee machine of the present invention is as follows: First, during the suspended layered installation of the present invention, the hanger 32 is mounted on the internal suspension of the commercial coffee machine. Bolts are inserted into the holes of the hanger 32 to securely fasten the hanger 32 to the internal suspension of the commercial coffee machine. Simultaneously, the bottom end of the collection cover 29 is docked with the coffee hopper of the commercial coffee machine. The top covers 31 are then rotated forward to separate and open the top covers 31 from the upper conveying box 1. Four types of coffee powders, namely coffee powder, vanilla powder, cocoa powder, and cinnamon powder, are then poured into the upper conveying boxes 1 for storage. The top covers 31 are then reversed and threadedly engaged with the upper conveying boxes 1, thereby closing the tops of the upper conveying boxes 1. The remaining four types of coffee powders, namely caramel powder, strawberry powder, milk powder, and almond powder, are then added to the feed tubes 30. These feed tubes 30 allow the coffee powders to enter the lower conveying box 16 for collection. The types of coffee powders are not fixed and can be added based on user preferences.

[0034] Secondly, when the present invention performs single-material or four-material synchronous switching conveying, when a single flavor is required to be conveyed and discharged, the delivery valve 28 is opened after wireless connection through the wireless controller 25, so that one of the upper conveying boxes 1 containing coffee powder conveys the coffee powder into the delivery pipe 9, and then conveys it into the delivery valve 28 through the delivery pipe 9, and the delivery valve 28 is used to realize the delivery and discharge. In this way, the coffee powder of a single flavor can be conveyed and discharged. After the delivery is completed, the delivery valve 28 is closed by the wireless controller 25.

[0035] When it is necessary to realize synchronous switching and conveying of four materials in layers, the wireless controller 25 is used to start the micro-electric cylinder 2, which pushes the connecting block 3 downward, and the connecting block 3 causes the frame bar 4 to move downward. The frame bar 4 moves downward synchronously along the outer wall of the multiple conveying upper boxes 1, and the frame bar 4 will drive the multiple linkage blocks 5 to move downward at the same time, and the multiple linkage blocks 5 respectively drive the multiple switching sealing plates 6 to move downward at the same time. When the switching sealing plate 6 moves downward, the switching sealing plate 6 will drive the conveying upper hole 7 to move downward, and at the same time, the switching sealing plate 6 drives the suspension rope 10 to move downward. Under the action of the tilting counterweight force of the sleeve slider 13 and the suspension sealing plate 11 itself, the suspension rope 10 slides downward along the inner wall of the sleeve 18, and at the same time, the suspension rope 10 slides downward along the inner wall of the arc strip 22, and the suspension rope 10 moves downward in a stable limited position along the limiting gap between the two limiting plates 20, and the suspension rope 10 slides downward on the outer wall of the positioning column 19. In this way, the hanging sealing plate 11 drives the sleeve slider 13 to move downwardly under the action of gravity, and the sleeve slider 13 is guided along the outer wall of the convex part of the convex slide column 14 to achieve inclined sliding, and the hanging sealing plate 11 can slide downwardly along the bottom end of the conveying pipe 17.

[0036] When the frame bar 4 moves downward, it will drive the connecting block 3 to move downward, and the connecting block 3 will drive the sensing block 24 to move downward, and the sensing block 24 will move away from the distance sensor 23. When the distance sensor 23 changes the distance between the sensing block 24 and the distance sensor 23 to a value of positive thirty centimeters, the micro-electric cylinder 2 will be turned off by the wireless controller 25, so that the sealing plate 6 is switched to transport and slide downward along the end of the conveying pipe 9, and the switching sealing plate 6 drives the upper conveying hole 7 to connect with the conveying pipe 9, and at the same time, the hanging sealing plate 11 moves downward to continue to block the feed pipe 17, so that the coffee powder, vanilla powder, cocoa powder and cinnamon powder inside the multiple conveying upper boxes 1 are discharged from the multiple conveying pipes 9 to the multiple conveying upper holes 7 respectively, and are transported to the inner wall of the collection cover 29 through the conveying upper holes 7. The coffee powder, vanilla powder, cocoa powder and cinnamon powder mixture can be collected on the inner wall of the collection cover 29 and discharged to the hopper of the commercial coffee machine for making coffee, so that the synchronous hanging conveying and unloading of the four kinds of coffee powder can be realized.

[0037] Then, when the present invention performs synchronous switching and conveying of eight kinds of materials in layers, when it is necessary to synchronously switch and convey eight kinds of materials in layers, the micro electric cylinder 2 is started by the wireless controller 25, and the micro electric cylinder 2 starts the micro electric cylinder 2 to drive the connecting block 3 to move upward, the connecting block 3 drives the frame bar 4 to move upward, the frame bar 4 drives multiple linkage blocks 5 to move upward synchronously, the linkage block 5 drives the switching sealing plate 6 to move upward, the switching sealing plate 6 slides upward along the end of the conveying pipe 9, and at the same time, the switching sealing plate 6 drives the top end of the suspension rope 10 to move upward synchronously, and the bottom end of the suspension rope 10 will drive the suspension sealing plate 11 to move upward obliquely.

[0038] The hanging sealing plate 11 drives the sleeve slider 13 to move up and tilt, and the sleeve slider 13 slides up and tilts along the convex part of the convex slide column 14. At the same time, the lower conveying box 16 supports the convex slide column 14, so that the convex part of the convex slide column 14 can achieve stable guided sliding of the sleeve slider 13. In this way, the hanging sealing plate 11 starts to move up and tilt. When the switching sealing plate 6 moves up and drives the conveying lower hole 8 to dock at the position of the conveying pipe 9, it is connected to the bottom end of the conveying pipe 17 through the conveying inclined hole 12 on the hanging sealing plate 11. At the same time, the distance sensor 23 senses the distance between the induction block 24 and the distance sensor 23. When the sensed value is 30 cm below the negative feed pipe, the micro cylinder 2 is turned off through the wireless controller 25. At this time, the coffee powder, vanilla powder, cocoa powder, and cinnamon powder in the multiple conveying upper boxes 1 enter the multiple conveying pipes 9 respectively, and are discharged into the multiple conveying lower holes 8 through the multiple conveying pipes 9. In this way, the four coffee powders, vanilla powder, cocoa powder, and cinnamon powder all enter the inclined plates 27 on the multiple limiting covers 26 to realize the downward discharge operation until the coffee powder, vanilla powder, cocoa powder, and cinnamon powder are conveyed to the inside of the collection cover 29. At the same time, the caramel powder, strawberry powder, milk powder, and almond powder in the multiple conveying lower boxes 16 respectively enter the multiple conveying pipes 17, and are discharged synchronously along the conveying inclined holes 12 through the multiple conveying pipes 17. In this way, the caramel powder, strawberry powder, milk powder, almond powder, coffee powder, vanilla powder, cocoa powder, and cinnamon powder are synchronously conveyed to the inside of the collecting cover 29, realizing the synchronous suspension and delivery of eight kinds of coffee powder, and delivering the discharge to the hopper of a commercial coffee machine for making coffee. In this way, the multiple conveying upper boxes 1 and the multiple conveying lower boxes 16 are arranged in layers, and intelligent switching between four kinds of coffee powder and eight kinds of coffee powder can be realized, which is used to realize the suspension and synchronous delivery of multiple types of coffee powder, and the conveying efficiency of coffee powder is higher.
