Description

Technical Field

[0001] This utility model belongs to the field of cake production technology, and in particular, it is a slurry injection device with a detachable, easy-to-clean injection head that eliminates the need for air removal. Background Technology

[0002] Cake is an ancient Western dessert, generally made in an oven. It's made primarily from eggs, sugar, and wheat flour, with milk, fruit juice, honey, milk powder, and water as secondary ingredients. After mixing, preparing, and baking, it becomes a sponge-like pastry. Cake products are diverse, especially since industrialization, with various processing techniques. The batter pouring methods can be divided into mold-pouring and flat-laying types. In mold-pouring, the baker pours the batter directly into paper cups or other molds through pouring holes, and then bakes them in the oven.

[0003] However, the existing injection head has a sharp surface that can easily puncture air bubbles in the slurry during injection and mixing, resulting in an overly thick slurry that affects the taste of the final product. In addition, the injection head has a complex structure that is extremely inconvenient to clean and disassemble.

[0004] In addition, in the utility model patent with publication number CN212464698U, the slurry is stirred and discharged by a stirring mechanism. However, the stirring mechanism is fixed on the shell, and it is not easy to clean the residue attached to it after stirring, which is not conducive to later use. Summary of the Invention

[0005] In view of this, the present invention provides a grouting device with a detachable, easy-to-clean, and air-free grouting head to solve the above problems.

[0006] A grouting device with a detachable, easy-to-clean, and air-free injection head includes an operating platform, a feed hopper connected to the operating platform, and a mixing and extrusion device connected to the feed hopper. The operating platform includes a mounting frame for supporting the feed hopper and the mixing and extrusion device. The feed hopper guides the slurry to the mixing and extrusion device, which includes at least two support columns on the mounting frame, a housing on the two support columns, a mixing and extrusion assembly within the housing, a set of connecting plate assemblies within the housing, and a drive motor on the mounting frame and connected to the mixing and extrusion assembly. The mixing and extrusion assembly includes a main mixing element connected to an output shaft and a secondary mixing element meshing with the main mixing element. The main mixing element and the secondary mixing element each include a plurality of first mixing protrusions and a plurality of second mixing protrusions. The first and second mixing protrusions are arc-shaped protrusions in cross-section perpendicular to the extension direction of the housing, and the surfaces of these arc-shaped protrusions are smoothly connected and polished without burrs. The drive motor is used to drive the main stirring component to move, and it includes an output shaft connected to the main stirring component. The connecting assembly includes a fixed plate sleeved on the output shaft and connected to one end of the housing, and a movable plate disposed opposite to the fixed plate and connected to one end of the housing. The fixed plate and the movable plate are respectively connected to both ends of the housing.

[0007] Furthermore, the feed box is a hollow inverted tower shape with openings on both sides.

[0008] Furthermore, the housing is used to house the stirring extrusion assembly.

[0009] Furthermore, the main stirring component also includes a first body and a plurality of first engagement grooves located on the first body and between two adjacent first stirring protrusions, the first stirring protrusions being located on the first body.

[0010] Furthermore, the agitator also includes a second body and a plurality of second engagement grooves located on the second body and between two adjacent second agitation protrusions, the second agitation protrusions being located on the second body.

[0011] Furthermore, the second stirring protrusion and the first engaging groove are adapted in size and shape.

[0012] Furthermore, the first stirring protrusion and the second engaging groove are matched in size and shape.

[0013] Furthermore, the grouting equipment with a detachable, easy-to-clean, and air-free injection head also includes an injection device connected to the mixing and extrusion device for injection. The injection device includes a mounting plate located at the bottom of the mixing and extrusion device and a plurality of injection nozzles spaced apart on the mounting plate.

[0014] Furthermore, the housing also includes two snap-fit ​​grooves for securing the injection device.

[0015] Compared with existing technologies, the grouting equipment with a detachable, easy-to-clean, and air-free injection head provided by this utility model stirs and extrudes the slurry by setting up the drive motor and the stirring and extrusion device. The drive motor includes an output shaft for connecting to the main stirring component. The stirring and extrusion device includes two support columns bolted to the mounting frame, a housing located between the two support columns, a stirring and extrusion assembly located inside the housing, and a set of connecting plate assemblies located on the housing. The connecting plate assembly includes a fixed plate sleeved outside the output shaft and connected to one end of the housing, and a movable rod plate opposite to the fixed plate and connected to the other end of the housing. During assembly, it is only necessary to assemble the support columns, the drive motor, the fixed plate, the housing, the stirring and extrusion assembly, and the movable plate in sequence. When it is necessary to disassemble and clean the stirring and extrusion assembly, it is only necessary to remove the movable plate and loosen the main stirring component from the output shaft to disassemble the stirring and extrusion assembly, thus making disassembly convenient and easy to clean. Furthermore, the stirring extrusion assembly includes multiple first stirring protrusions and multiple second stirring protrusions. Both the first stirring protrusions and the second stirring protrusions are arc-shaped protrusions in the extension direction perpendicular to the shell. The surface of the arc-shaped protrusions is smooth and connected without sharp protrusions, and their surfaces are all polished and free of burrs. This ensures that the air in the batter is not punctured during stirring, resulting in a softer cake with a better taste. Attached Figure Description

[0021] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0022] like Figures 1 to 5 The diagram shows a structural schematic of a grouting device with a detachable, easy-to-clean, and air-free injection head, as provided by this utility model. The grouting device includes an operating platform 10, a feed box 20 connected to the operating platform 10, a stirring and extrusion device 30 connected to the feed box 20, and an injection device 40 connected to the stirring and extrusion device 30. The grouting device also includes other functional modules, such as installation components and electrical connection components, which are technologies known to those skilled in the art and will not be described in detail here.

[0023] like Figure 1 As shown, the operating table 10 is used to support the feed box 20, the stirring extrusion device 30, and the injection device 40. The operating table 10 includes an operating surface 11 and a mounting bracket 12 for supporting the feed box 20 and the stirring extrusion device 30.

[0024] When the grouting equipment injects grout, the operating table 11 should be placed with a tray (not shown) or other support for holding the grout. This should be known to those skilled in the art and will not be described in detail here.

[0025] The structure and shape of the mounting bracket 12 are designed to fix the feed box 20 and the stirring extrusion device 30, so its specific structure and shape will not be described in detail here.

[0026] like Figure 2 As shown, the feed box 20 is used to guide the externally poured slurry to the stirring extrusion device 30. The shape of its box body can be a hollow inverted tower shape with openings at both ends for slurry inflow and outflow.

[0027] like Figure 2As shown, the stirring extrusion device 30 is used to stir the slurry conveyed by the feed box 20 and convey it to the injection device 40. It includes at least two support columns 31 located on the mounting frame 12, a housing 32 located on the two support columns 31, a stirring extrusion assembly 33 located in the housing 32, a set of connecting plate assemblies 34 located on the housing 32, and a drive motor 35 connected to the stirring extrusion assembly 33.

[0028] The support column 31 is used to support the housing 32, and it can be fixed to the mounting bracket 12 by bolts or other fasteners.

[0029] The housing 32 is used to accommodate the stirring extrusion assembly 33, and it can be a hollow housing with openings on both sides. The shape of the housing 32 is designed to just accommodate and place the stirring extrusion assembly 33, so its specific shape and structure will not be described in detail here. It is easy to imagine that the surface of the housing 32 also has multiple screw holes for connecting to the support column 31, the connecting plate assembly 34, and the output shaft 351 for easy screwing and fixing. This should be well known to those skilled in the art, and will not be elaborated further here.

[0030] like Figure 3 As shown, the housing 32 also includes two snap-fit ​​grooves 321 formed on the side of the housing 32 away from the feed box 20 for fixing the injection device 40. The two snap-fit ​​grooves 321 are arranged opposite to each other, and each snap-fit ​​groove has a concave groove in cross-section perpendicular to the extending direction of the housing 32.

[0031] The stirring and extrusion assembly 33 is used to stir and extrude the slurry conveyed by the feed box 20. It includes a main stirring component 331 connected to the drive motor 35 and a secondary stirring component 332 engaged with the main stirring component 331.

[0032] like Figure 4 As shown, the main stirring member 331 is used to cooperate with the secondary stirring member 332 under the power drive of the drive motor 35 to stir and extrude the incoming slurry. It includes a first body 333, a plurality of first stirring protrusions 334 located on the first body 333 and spaced apart, and a plurality of first engaging grooves 335 located on the first body 333 and located between two adjacent first stirring protrusions 334.

[0033] The first body 333 is used to support the first stirring protrusion 334 and the first engagement groove 335, and it can be a cylinder.

[0034] The first stirring protrusion 334 is an arc-shaped protrusion in a cross-section perpendicular to the extension direction of the first body 333. The surface of this arc-shaped protrusion is smooth and free of sharp protrusions, and it is also polished to ensure a burr-free surface. The first stirring protrusion 334 has the same extension length as the first body 333. Because the surface of the first stirring protrusion 334 is smooth and free of sharp protrusions, it will not puncture air bubbles in the batter during stirring and extrusion, resulting in a fluffy and delicious cake product.

[0035] The first engagement groove 335 is located between two adjacent first stirring protrusions 334, and is an arc-shaped groove in a cross-section perpendicular to the extension direction of the first body 33. The arc-shaped groove is smoothly connected without sharp pits, and its surface is also polished to ensure that its surface is free of burrs.

[0036] like Figure 3 As shown, the slave agitator 332 has the same structure and function as the main agitator 331. For ease of understanding, only its components are briefly described here. The slave agitator 332 includes a second body 336, a plurality of second agitation protrusions 337 located on the second body 336, and a plurality of second engagement grooves 338 located on the second body 336 and between adjacent pairs of second agitation protrusions 337.

[0037] The first stirring protrusion 334 and the second stirring protrusion 337 are respectively adapted to the size and shape of the second engaging groove 338 and the first engaging groove 335. When the main stirring member 331 rotates under the action of the drive motor 35, the secondary stirring member 332 rotates accordingly and rotates relative to the main stirring member 331. During rotation, the first stirring protrusion 334 inserts into the second engaging groove 338 and engages with each other, and the second stirring protrusion 337 inserts into the first engaging groove 335 and engages with each other to stir the batter. The surfaces of the first stirring protrusion 334 and the second stirring protrusion 337 are polished smooth to prevent puncturing air bubbles in the batter during stirring, thus resulting in a soft texture for the cake made later. When the first stirring protrusion 334 and the second stirring protrusion 337 engage and rotate, the volume of the space on the side of the stirring extrusion assembly 33 facing the feed box 20, i.e. the gear disengagement side, increases from small to large, forming a vacuum, thereby drawing in the slurry. The volume of the side of the stirring extrusion assembly 33 facing the injection device 40, i.e. the gear engagement side, decreases from large to small, thereby squeezing the slurry into the injection device 40.

[0038] The connecting plate assembly 34 is used to fix the stirring extrusion assembly 33 onto the housing 32. It includes a fixed plate 341 sleeved on the output shaft 351 and connected to one end of the housing 32, and a movable plate 342 disposed opposite to the fixed plate 341 and connected to the other end of the housing 32. The connecting plate assembly 34 can be a rectangular plate and fixed to the housing 32 with screws.

[0039] The fixing plate 341 is used to cooperate with the movable plate 342 to fix the stirring extrusion assembly 33 inside the housing 32, and it is located between the mounting bracket 12 and the housing 32. The fixing plate 341 includes a mounting hole 3411 for the output shaft 351 to pass through. The fixing plate 341 can be a rectangular plate and is fixed between the mounting bracket 12 and the housing 32 by fasteners such as bolts.

[0040] The movable plate 342 and the fixed plate 341 are located at opposite ends of the housing 32. The movable plate 342 can be a rectangular plate and is fixed to one end of the housing 32 by bolts or other fasteners.

[0041] The drive motor 35 drives the main stirring component 331 to move, and includes an output shaft 351. The output shaft 351 is used to fix the main stirring component 331 to the drive motor 35, and is keyed to the main stirring component 331. One end of the output shaft 351 passes through the mounting hole 3411 and is connected to the drive motor 35, while the other end is connected to the main stirring component 331, thereby fixing the main stirring component 331 relative to the drive motor 35 and allowing the main stirring component 331 to move with the drive motor 35. Keyed connection is a common mechanical connection method, mainly used for transmitting torque and load; it should be well known to those skilled in the art and will not be elaborated further here.

[0042] When assembling the mixing and extrusion device 30, first, bolt the support column 31 and the drive motor 35 to the mounting frame 12. Then, bolt the fixing plate 341 through the output shaft 351 to the mounting frame 12. Next, place the housing 32 on the support column 31 and push the housing 32 until it abuts against the fixing plate 341. After it abuts, bolt the housing 32 to the fixing plate 341 and the support column 31. Then, insert the main mixing component 331 and the secondary mixing component 332 into the housing 32 through the opening at the other end of the housing 31. At this time, the main mixing component 331 should be facing the output shaft 351 and fixed by a key connection. At this time, the main mixing component 331 is fixed relative to the drive motor 35. Finally, screw the movable plate 342 to the other end of the housing 32. At this point, the main agitator 331 and the secondary agitator 332 are respectively abutted against the fixed plate 341 and the movable plate 342 to be fixed within the housing 32. It is easy to see that the lengths of the main agitator 331 and the secondary agitator 332 are approximately equal to the distance between the fixed plate 341 and the movable plate 342. When cleaning the mixing and extrusion assembly 33 is required, simply remove the movable plate 342 and detach the main agitator 331 from the output shaft 351 to remove the main agitator 331 and the secondary agitator 332 for cleaning.

[0043] like Figure 5 As shown, the injection device 40 is used to inject the slurry, which has been stirred and extruded by the stirring and extruding device 30, onto a carrier such as a tray (not shown) on the operating table 11. The injection device 40 is located on the side of the stirring and extruding device 30 away from the feed box 20, and includes a mounting plate 41 inserted into the snap-fit ​​groove 321, and a plurality of injection nozzles 42 spaced apart on the mounting plate 41.

[0044] The mounting plate 42 is used to support and place the injection nozzle 42. It can be a rectangular strip and snapped into the snap-fit ​​groove 321.

[0045] The injection nozzle 42 is used to inject slurry onto a carrier such as a tray (not shown) on the operating table 11. This is a well-known fact among those skilled in the art and will not be described in detail here. The number of injection nozzles 42 can be set according to actual needs. In this embodiment, the number of injection nozzles 42 is four.

[0046] Compared with the prior art, the grouting equipment with a detachable, easy-to-clean, and air-free injection head provided by this utility model stirs and extrudes the slurry by setting up the drive motor 35 and the stirring and extrusion device 30. The drive motor 35 includes an output shaft 351 for connecting to the main stirring component 331. The stirring and extrusion device 30 includes two support columns 31 bolted to the mounting frame 12, a housing 32 located between the two support columns 31, a stirring and extrusion assembly 33 located inside the housing 32, and a set of connecting plate assemblies 34 located on the housing 32. The connecting plate assembly 34 includes a fixed plate 341 sleeved outside the output shaft 341 and connected to one end of the housing 32, and a movable rod plate 342 opposite to the fixed plate 341 and connected to the other end of the housing 32. During assembly, it is only necessary to assemble the support columns 31, the drive motor 35, the fixed plate 341, the housing 32, the stirring and extrusion assembly 33, and the movable plate 342 in sequence to complete the assembly. When it is necessary to disassemble and clean the mixing and extrusion assembly 33, it is only necessary to remove the movable plate 342 and loosen the main mixing element 331 from the output shaft 351 to disassemble the mixing and extrusion assembly 33, which makes disassembly convenient and easy to clean. The mixing and extrusion assembly 33 includes multiple first mixing protrusions 334 and multiple second mixing protrusions 337. The first mixing protrusions 334 and the second mixing protrusions 337 are all arc-shaped protrusions in the extension direction perpendicular to the housing 32. The surface of the arc-shaped protrusions is smooth and connected without sharp protrusions, and their surfaces are all polished and free of burrs, so that the air in the batter will not be punctured during mixing, resulting in a softer cake with a better taste.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
