Description

Technical Field

[0001] The invention relates to the technical field of dough mixer cooling mechanisms, in particular to a cooling water guide plate and a dough mixer cooling component. Background Art

[0002] The dough mixer is a type of pasta machine, and its main function is to mix flour and water evenly. Large-scale dough mixing can be carried out by holding a large amount of flour and water in a dough barrel (or dough cylinder, material barrel). However, during the dough mixing process, the high-speed friction between the hook (i.e., stirring tool) and the barrel wall will cause the dough temperature to gradually increase. When the dough temperature is above 30°, the dough yeast will react and even burn the yeast, causing the yeast to lose its fermentation function, and then the dough will become scrap dead dough.

[0003] Therefore, in the conventional technology, a common method is to inject ice cubes into the dough barrel (or dough cylinder, i.e., the barrel for holding the dough) of the dough mixer during the dough mixing process (the ice cubes are crushed by an ice crusher and then mixed). Obviously, according to the existing dough mixer structure, directly injecting ice water into the dough barrel through a water pipe can indeed cool the dough, but it consumes a large amount of ice cubes and is costly; moreover, the need to configure an ice crusher further increases the production cost.

[0004] As a technical improvement, the dough mixer cooling device and the dough mixer including the device disclosed in the application document with application number CN201911182179.6 previously applied by the same applicant perform physical cooling through the heat exchange cavity, thereby solving the technical problem of cooling the fabric.

[0005] However, the cooling effect of the device on fabrics still needs to be further improved. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, one of the objects of the present invention is to provide a cooling water guide tray, which can further improve the cooling effect of the dough mixer.

[0007] A second object of the present invention is to provide a dough mixer cooling assembly.

[0008] One of the purposes of the present invention is achieved by the following technical solution:

[0009] A cooling water guide plate comprises a plate body, wherein the plate body is provided with a water inlet through hole and a water outlet through hole spaced apart from the water inlet through hole along its own axial direction; the upper end surface of the plate body is recessed to form a water inlet groove and a water outlet groove; one end of the water inlet groove is connected to the water inlet through hole, and the other end of the water inlet groove penetrates to the side wall of the plate body; one end of the water outlet groove is connected to the water outlet through hole, and the other end of the water outlet groove penetrates to the side wall of the plate body.

[0010] Furthermore, the water inlet through hole and the water outlet through hole are symmetrical about the axis of the disk.

[0011] Furthermore, the water inlet groove and the water outlet groove are symmetrical about the axis of the disk body.

[0012] Furthermore, the water inlet trough includes a plurality of first arc segments and a plurality of first connecting segments, the ends of adjacent first arc segments are connected through the first connecting segments, and the radii of the plurality of first arc segments gradually increase from the inside to the outside along the radial direction of the disk body; the water outlet trough includes a plurality of second arc segments and a plurality of second connecting segments, the ends of adjacent second arc segments are connected through the second connecting segments, and the radii of the plurality of second arc segments gradually increase from the inside to the outside along the radial direction of the disk body.

[0013] Furthermore, the first connecting section and the second connecting section are both straight sections, and the first connecting section extends along the radial direction of the disk body, and the second connecting section extends along the radial direction of the disk body; the first connecting section at the outermost edge of the disk body penetrates the side wall of the disk body from the inside to the outside along the radial direction of the disk body; the second connecting section at the outermost edge of the disk body penetrates the side wall of the disk body from the inside to the outside along the radial direction of the disk body.

[0014] Furthermore, the disc body is provided with a positioning hole, and the positioning hole is used to connect the rotating shaft of the dough mixer.

[0015] Furthermore, the positioning hole is a special-shaped hole.

[0016] The second object of the present invention is achieved by adopting the following technical solution:

[0017] The cooling assembly of the dough mixer comprises a dough barrel and the cooling water guide plate; a heat exchange cavity is formed between the inner wall of the dough barrel and the outer wall of the dough barrel; the water inlet through hole and the water outlet through hole are both connected to the heat exchange cavity; the upper end surface of the plate is fixedly connected to the inner wall of the dough barrel, and the lower end surface or side surface of the plate is connected to the outer wall of the dough barrel to cover the heat exchange cavity.

[0018] Furthermore, the heat exchange cavity surrounds the entire circumference of the noodle barrel, and is at least enclosed by the bottom wall and side walls of the inner wall of the noodle barrel and the bottom wall and side walls of the outer wall of the noodle barrel.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The inner wall of the opposite barrel is supported by the plate body of the cooling water guide plate, that is, the opposite barrel is reliably supported by the plate body, especially when the weight of the fabric is large and the rotating shaft is running, the smooth operation of the dough mixer is guaranteed.

[0021] 2. By arranging water inlet holes and water outlet holes on the disc body, when used in combination with the rotating shaft, it is only necessary to open a water inlet channel and a water outlet channel on the rotating shaft, making the arrangement method of the rotating shaft more excellent.

[0022] 3. The water flow direction is guided through the water inlet and outlet grooves of the tray body, so as to facilitate the circulation of cooling water and the bottom of the noodle bucket and stably cool down the temperature, thereby ensuring the fluidity of the cooling water at the bottom of the inner wall of the noodle bucket and improving the cooling effect of the noodle bucket.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] See also Figure 1-Figure 5 A dough mixer according to a preferred embodiment of the present invention includes a dough barrel 1, a rotating shaft 2 and a sealing mechanism 3.

[0036] A heat exchange cavity 11 is formed between the inner wall of the noodle barrel 1 and the outer wall of the noodle barrel 1. The heat exchange cavity 11 is used to contain cooling water so that the inner wall of the noodle barrel 1 can be cooled by circulating the cooling water, thereby cooling the fabric in the noodle barrel 1. The rotating shaft 2 is provided with a water inlet 21 and a water outlet 22, and the first end of the water inlet 21 and the first end of the water outlet 22 both extend along the axial direction of the rotating shaft 2 itself, so that the cooling water can be circulated and transported through the interior of the rotating shaft 2 when the barrel surface rotates.

[0037] The sealing mechanism 3 includes a housing 31, a mechanical seal 32 and a spacer 33. The housing 31 has a water inlet cavity 311. The mechanical seal 32 is arranged in the water inlet cavity 311. The mechanical seal 32 includes two dynamic rings 321 and two static rings 322. The dynamic ring 321 and the static ring 322 are both sleeved on the rotating shaft 2. The two static rings 322 respectively abut against the housing 31. The two dynamic rings 321 are respectively located between the two static rings 322. The spacer 33 is arranged between the two dynamic rings 321. The rotating shaft 2 is provided with a water hole 23 along its radial direction. Under the premise of providing the spacer 33, the two ends of the water hole 23 are conveniently connected to the first end of the water inlet 21 and the water inlet cavity 311 respectively (for example, the spacer 33 can be a frame structure). The first end of the water outlet 22 penetrates the side curved wall of the rotating shaft 2 or the end of the rotating shaft 2 away from the noodle barrel 1. It should be noted here that when the first end of the water outlet 22 passes through the side curved wall of the rotating shaft 2, it can be fixedly connected to the first end of the water outlet pipe 35 through a pipe, and the other end of the pipe is connected to a water tank that rotates with the rotating shaft 2; however, in the present embodiment, it is a preferred embodiment to have the first end of the water outlet 22 pass through the end of the rotating shaft 2 away from the noodle barrel 1.

[0038] See also Figure 6-Figure 8 The dough mixer further comprises a cooling water guide plate 4, wherein the cooling water guide plate and the dough barrel 1 form a dough mixer cooling assembly. The upper end surface of the plate 4 is fixedly connected to the inner wall of the dough barrel 1 (preferably welded to seal the gap), and the lower end surface or side surface of the plate 4 is connected to the outer wall of the dough barrel 1 to cover the heat exchange cavity 11. The plate 4 is provided with a water inlet through hole 41 and a water outlet through hole 42 spaced apart from the water inlet through hole 41 along its axial direction. Figure 4 The water inlet through hole 41 is connected to the second end of the water inlet channel 21, and the water outlet through hole 42 is connected to the second end of the water outlet channel 22. Figure 6 The upper end surface of the disk body 4 is indented to form a water inlet groove 43 and a water outlet groove 44. One end of the water inlet groove 43 is connected to the water inlet through hole 41, and the other end of the water inlet groove 43 penetrates the side wall of the disk body 4 and communicates with the heat exchange cavity 11. One end of the water outlet groove 44 is connected to the water outlet through hole 42, and the other end of the water outlet groove 44 penetrates the side wall of the disk body 4 and communicates with the heat exchange cavity 11.

[0039] When working, combine Figure 2-Figure 4 The water flow route is: water inlet 21 → water inlet hole 41 → water inlet groove 43 → heat exchange cavity 11 → water outlet groove 44 → water outlet hole 42 → water outlet 22. It can be understood that the direction of water flow can also be countercurrent, that is, water is discharged from the water inlet 21 and water is in the water outlet 22.

[0040] Obviously, by supporting the inner wall of the noodle barrel 1 with the cooling water guide plate 4, the noodle barrel 1 can be reliably supported, especially when the weight of the fabric is large and the rotating shaft 2 is running, the smooth operation of the noodle mixer is guaranteed. At the same time, by setting the water inlet through hole 41 and the water outlet through hole 42 on the plate 4, the rotating shaft 2 only needs to be provided with the water inlet channel 21 and the water outlet channel 22, so that the setting method of the rotating shaft 2 is better. In addition, the water flow direction is guided by the water inlet groove 43 and the water outlet groove 44, so as to facilitate the circulation of cooling water and the bottom of the noodle barrel 1 and stably cool down, so as to ensure the fluidity of the cooling water at the bottom of the inner wall of the noodle barrel 1; it should be supplemented here that, compared with the noodle mixer cooling device disclosed in the application document with application number CN201911182179.6 previously applied by the same applicant and the noodle mixer including the device, the water inlet groove 43 and the water outlet groove 44 ensure the fluidity of the cooling water on the inner wall of the noodle barrel 1.

[0041] As a further preferred embodiment: see Figure 6 The water inlet through hole 41 and the water outlet through hole 42 are symmetrical about the axis of the disc body 4, so that it is beneficial to distribute the routes of the water inlet groove 43 and the water outlet groove 44, and the rotation of the disc body 4 can better meet the dynamic balance requirements.

[0042] As a further preferred embodiment: see Figure 6 The water inlet groove 43 and the water outlet groove 44 are symmetrical about the axis of the disk body 4, so that the water inlet groove 43 and the water outlet groove 44 can be prevented from crossing each other, and the rotation of the disk body 4 can be further made to meet the dynamic balance requirements. In addition, the port of the water inlet groove 43 and the port of the water outlet groove 44 are arranged opposite to each other, that is, the cooling water enters the heat exchange cavity 11 from the water inlet groove 43 and flows to a certain extent before it can flow out along the water outlet groove 44, thereby ensuring the sufficient cooling effect of the cooling water.

[0043] As a further preferred embodiment: see Figure 6 The water inlet groove 43 includes a plurality of first arc segments 431 and a plurality of first connecting segments 432, the ends of adjacent first arc segments 431 are connected by the first connecting segments 432, and the radii of the plurality of first arc segments 431 gradually increase from inside to outside along the radial direction of the disk body 4. The water outlet groove 44 includes a plurality of second arc segments 441 and a plurality of second connecting segments 442, the ends of adjacent second arc segments 441 are connected by the second connecting segments 442, and the radii of the plurality of second arc segments 441 gradually increase from inside to outside along the radial direction of the disk body 4.

[0044] As a further preferred embodiment: see Figure 6, the first connecting section 432 and the second connecting section 442 are both straight sections, and the first connecting section 432 extends in the radial direction of the disk body 4, and the second connecting section 442 extends in the radial direction of the disk body 4. The first connecting section 432 at the outermost edge of the disk body 4 penetrates the side wall of the disk body 4 from inside to outside along the radial direction of the disk body 4. The second connecting section 442 at the outermost edge of the disk body 4 penetrates the side wall of the disk body 4 from inside to outside along the radial direction of the disk body 4. Such a configuration is not only conducive to the processing and manufacturing of the disk body 4, but also allows the water inlet groove 43 and the water outlet groove 44 to occupy more area of ​​the disk body 4, so as to ensure that the cooling water flows through more parts of the disk body 4.

[0045] As a further preferred embodiment: see Figure 4 and Figure 6 The plate body 4 is provided with a positioning hole 45, and the positioning hole 45 is used to connect the rotating shaft 2 of the dough mixer; thus, it is convenient to install the plate body 4. More preferably, the positioning hole 45 is a special-shaped hole (according to common knowledge, any hole shape other than a circle is called a special-shaped hole), so as to avoid slippage between the rotating shaft 2 and the plate body 4.

[0046] As a further preferred embodiment: the heat exchange cavity 11 surrounds the entire periphery of the noodle barrel 1 and is at least enclosed by the bottom wall and side walls of the inner wall of the noodle barrel 1 and the bottom wall and side walls of the outer wall of the noodle barrel 1. This arrangement can ensure a larger heat exchange area.

[0047] As a further preferred embodiment: the rotating shaft 2 is located directly below the disk body 4, the rotating shaft 2 comprises a shaft body 24 and a support plate 25 fixed to the top of the shaft body 24, the support plate 25 is fixedly connected to the disk body 4, and the water inlet 21 and the water outlet 22 are both arranged on the shaft body 24. In this way, the processing difficulty of the rotating shaft 2 can be reduced.

[0048] As a further preferred embodiment: see Figure 3 The housing 31, the end of the rotating shaft 2, and one of the stationary rings 322 enclose a water outlet cavity 34, and the first end of the water outlet 22 passes through the water outlet cavity 34. The dough mixer also includes a water outlet pipe 35, and the water outlet pipe 35 is connected to the water outlet cavity 34. The isolation member 33 is an annular baffle, which is fixedly sleeved on the rotating shaft 2, and the baffle is provided with a water hole 331 that passes through its inner wall and outer wall. The water hole 23 is connected to the water inlet cavity 311 through the water hole 331; the water inlet cavity 311 is connected to a water inlet pipe 36.

[0049] See also Figure 5The dough mixer also includes a motor, a driving wheel 5 connected to the motor, and a driven wheel 6 connected to the driving wheel 5, wherein the driven wheel 6 is fixedly sleeved on the rotating shaft 2. The driving wheel 5 can be a rotating element of a gear, a sprocket or other structure, as long as the rotating shaft 2 can be driven, thereby ensuring that the dough barrel 1 can rotate, and the ability of the dough barrel 1 to rotate is conducive to improving the dough mixing efficiency. That is to say, in the present invention, the rotating shaft 2 does not necessarily have to be able to rotate, and being able to achieve the cooling function is the key point of the present invention, and the mechanical seal 32 provides a basis for it to rotate (such as when necessary or frequently rotate), that is, transmitting it through the driven wheel 6 is only a preferred embodiment.

[0050] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
