Description

Wet and dry type roll mill

The present invention relates to a wet type and dry type roll mill, and more particularly to a roll mill structure which is upright and which is fed from the upper end and collects the finished product from the lower end.

Grinding machinery is a commonly used machine in the industry. Whether it is applied to metal powder, food powder, pharmaceutical powder, cosmetics, fertilizer, stone powder, chemical pulverization or grinding, although it is ingeniously different in manufacturing, mainly The design is the direction of the dry pulverizer. Please refer to Figure 8 for the conventional dry pulverizer. It is mainly provided with an upper and lower communicating cylinder 80, and a crushing chamber 81 is arranged at the middle position. A pulverizing mechanism 90 is disposed in the chamber 81. The pulverizing mechanism 90 has a main shaft 91 which is driven by a transmission mechanism 93 below the cylinder bottom 85 and can drive an oscillating cutter 92 to pulverize the material; The upper part of the chamber 81 is driven by a motor 82 to rotate a grading blade 83, mainly as a function of separating the powder size. An upper end of the pulverizing chamber 81 is outwardly connected with an exhaust pipe 84, and the exhaust pipe 84 is connected at the other end. In the pumping system, the fine powder ground from the pulverizing mechanism 90 can be extracted and collected by the air pumping from above the cylinder 80.

Therefore, when using the dry pulverizer as shown in Fig. 8, it is necessary to carry out a lot of additional tools, such as pumping up the powder with a powerful pumping system, filtering and separating it. Fine powder collection, so the design of the conventional dry pulverizer The calculation is more complicated.

However, one of the most obvious disadvantages of the above-mentioned dry pulverizer is that it is ground or cut in a dry environment, and a special product, such as a food material, causes a large rate of starch damage, resulting in poor quality of the granules. In addition, materials with a soft texture or materials with a high water content cannot be used on such dry implements, so the dry grinding method is limited in the range of use of the materials.

Another disadvantage of the conventional dry pulverizer is that since the powder must be taken up and collected, the use of energy, especially the power supply of the air supply system, is very expensive, and the maintenance on the gas guiding system is also very expensive. Cost, and occupying a larger site, is its main drawback.

In addition, the conventional dry pulverizing machine is used, and there are many pipe components attached. Therefore, after using a material for pulverizing work, and then changing a material, the dry pulverizer and its accessories and tools should be cleaned together to avoid The residual raw material once is mixed with another new raw material pulverized by the second type, so the cleaning work becomes very complicated and takes time, which is another disadvantage of the conventional pulverizer.

[Problems to be solved by the present invention]

When the food material is ground, the oil, sugar, fiber, flavor, and the like of the material component, and the specific gravity of the pulverized material, moisture, and a fine particle size range, component loss, acidification effect, and easy-to-use product which the customer desires are fine. In the middle of the process, the range of pulverization is very small, which is a problem that cannot be solved by conventional use.

At the same time, in the dry and wet mode, the pulverizer can be used at the same time. At present, there is no such machine. In addition, in recent years, environmentalism has risen, and it is required for the machine. Saving energy, space, and requiring powdering to meet the requirements of simplification, but although there is a demand for these pulverizers, it is actually difficult to break through. The main reason is that most of the grinding mechanisms used are conventionally used. When the planetary grinding method is used, when the stator is hit by centrifugal force, the material enters the peripheral contact surface of the cutter wheel and the stator due to the large or small input material. The centrifugal force is generated due to the weight of the grinding mechanism, and the tapping is repeated. The effect of mashing, slowly and subtly. Therefore, in order to obtain the required powder characteristics and particle size, it is necessary to design the difference between the upper and lower sides in the gap between the grinding mechanism of the pulverizing portion and the stator.

At the same time, when there are many materials such as fats and saccharides, oils, sugars, and the like appear due to knocking and mashing, and they adhere to the pulverizing chamber. In addition, in the case of spices, the aroma components are scarred, causing unusable powder and causing waste.

Therefore, the present invention has an object of solving such a problem, and an object of the present invention is to adjust a load on a pulverizing mechanism, a length of a cutter wheel, and a gap between stators in advance, and to provide a rolling type capable of improving powdering according to the shape of the outer peripheral surface of the cutter wheel. Grinding.

The main object of the present invention is to design a wet and dry dual-purpose pulverizer, which not only saves the relevant powerful pumping system in the original dry pulverization, but also eliminates many tubes and filtered components for collecting fine powder. The cost of the purchase is greatly reduced, and the energy for generating the air supply system and the equipment for the flow guiding line can be eliminated, which is more economical and practical.

Another object of the present invention is that it is more convenient to clean up because the above-mentioned pumping system and pipe fittings are omitted, so that it is particularly suitable for small-volume production and various crushing work, after each crushing work, the cleaning will be It is very convenient for another smashing, which will not cause huge cleaning work and manpower, and the cost will be more economical.

Still another object of the present invention is to enable pulverization for wet type at the same time, and it is suitable for pulverizing and grinding of foods or medicines, and the pulverizer can be used in a wider range.

In order to achieve the above object, the present invention can be achieved by providing a cylinder having a pulverization chamber at an upper end and a feed hole and an intake hole at an upper peripheral side of the pulverization chamber. And the feeding hole is connected with a feeding pipe; and a discharging hole is arranged below the crushing chamber; a spindle is penetrated from the top or bottom of the crushing chamber, and is axially connected by a bearing. The outer end is connected with a transmission mechanism, and the main shaft is provided with a pulverizing mechanism inside the pulverizing chamber; a pulverizing mechanism is disposed on the main shaft and is respectively provided with a top plate and a seat plate, and is driven by the transmission mechanism to rotate; Wherein, the top plate and the seat plate are respectively provided with through holes and inner holes through which the raw materials pass, and the seat plate is further provided with a plurality of elongated guide holes, and the top plate is provided with a universal joint with respect to the position of the guide holes a plurality of rotatable cutter wheels are disposed between the top plate and the seat plate, and the cutter wheels have a center wheel bar, one end of which is engaged with the universal joint, and the other end is inserted into the seat plate.

Referring to Figures 1 and 5, a first embodiment of the wet and dry-type roll mill of the present invention is mainly provided with a cylinder 10, and a crushing chamber 11 is provided at the upper end, and the crushing chamber is provided. Immediately below, the discharge hole 114 is provided, and a funnel-shaped converging end 12 is provided along the outer edge of the discharge hole 114; a feed hole 112 and a feed hole are respectively provided on the upper peripheral side of the crushing chamber 11 The air hole 113, and the feed hole 112 and the air inlet hole 113 are respectively connected to a feeding pipe 13 and an air pipe 14, and the position of the feeding pipe 13 and the air pipe 14 is required for the crushing chamber 11 of the cylinder 10 The material may be disposed in a tangential manner such that the material entering from the feed hole 112 and the gas injected from the gas inlet hole 113 can enter the inside along the wall edge of the pulverization chamber 11.

Referring to FIG. 1 , a spindle 20 is inserted through the top 111 of the crushing chamber 11 and is axially connected by a bearing 21 . The transmission mechanism 30 is connected to the outer end of the spindle 20 (the transmission mechanism is The conventional rotary power source, the present invention is only illustrated by a pulley, is driven by a motor, and the main shaft 20 is provided with a pulverizing mechanism 40 (as shown in Fig. 2) inside the pulverizing chamber 11.

Please refer to the first, second, and third figures, a pulverizing mechanism 40, which is sleeved on the main shaft. The top plate 42 and the seat plate 41 are respectively rotated by the transmission mechanism 30; wherein the top plate 42 and the seat plate 41 are respectively provided with a through hole 421 and an inner hole 4110 through which the raw material passes, and the seat plate 41 The upper hole is further provided with a plurality of long guide holes 412, and the top plate 42 is provided with a universal joint 44 at a position relative to the guide hole 412; as shown in FIG. 2, the inner hole 4110 of the seat plate 41 can be provided. On an adjustment block 411, the adjustment block 411 is an active group disposed on the seat plate 41. In order to different materials during grinding, it is necessary to use inner holes 4110 of different sizes to obtain the best time for grinding the raw materials. It is only necessary to replace the adjustment block 411 having a different inner hole 4110 for different raw materials.

A plurality of rotatable cutter wheels 43 are disposed between the top plate 42 and the seat plate 41, and the cutter wheels 43 have a center wheel bar 431. The upper end 4312 of the wheel bar 431 is engaged with the universal joint 44. The lower end 4311 is inserted into the guide hole 412 of the seat plate 41; as shown in Fig. 4-1, the teeth 430 of the cutter wheel 43 can be changed depending on the material.

Since the present invention is to design a wet and dry pulverizer, the special raw material will release moisture when pulverized, and the raw material itself will be more viscous; in addition, since the present invention is particularly suitable for frequent replacement of materials. Flushing with clean water is the quickest choice for cleaning. Therefore, under the high-speed rotation of the cutter wheel 43, it is designed to be damaged by friction heat when rotating, but it can effectively block moisture and foreign matter when stopping the rotation. It is very important to invade the shaft seal design of the shaft member. At this time, if the general contact type oil seal currently used in the market is used, when the cutter wheel 43 is rotated at a high speed as shown in FIG. 3, the friction generated causes high temperature to damage and contaminate the raw material, and it is necessary to design a kind. A new sealing mechanism; see Figures 3, 4-2, and 4-3, the two-axis seals 45 are respectively sleeved on the wheel 431 and attached to the upper and lower ends 432 of the cutter wheel 43. The shaft seal 45 is formed with a protruding portion 451 near the upper and lower end faces 432 of the cutter wheel 43. The protruding portion 451 is more elastic, and a concave arc portion 452 is provided at a middle portion of the two-axis seal 45. The two-axis seal 45 is sealed to the upper and lower end faces 432 of the cutter wheel 43 by the protruding portion 451 to prevent Water penetrates between the wheel bars 431 of the cutter wheel 43.

Referring to the first, second, and third figures, the stator 50 is disposed on the inner wall of the pulverizing chamber 11 with respect to the cutter wheel 43 of the pulverizing mechanism 40. The stator 50 and the cutter wheel 43 are used for the purpose. The material is tapped, cut, stretched, and ground in order to have a better space for accommodating raw materials, and at the same time has the functions of tapping, cutting, rolling, and grinding; and at the inner side of the stator 50 There is not a full contact with the tread of the cutter wheel 43, but a slanted or tapered storage space 60 for easy entry of the material, and only the lower half of the tread and the stator of the cutter wheel 43 50 The action of tapping, grinding, cutting, and cutting is performed, and the material is ground finer.

Referring to FIGS. 3, 4, and 4-4, when the cutter wheel 43 of the pulverizing mechanism 40 rotates, the protruding portion 451 of the shaft seal 45 can be slightly separated from the end surface 432 of the cutter wheel 43 to form a gap S. The actual test can reach about 0.1, which can reduce the heat caused by the friction and effectively suppress the temperature transmitted by the cutter wheel 43. However, when the rotation stops, the protrusion 451 of the shaft seal 45 is reset and attached to the cutter wheel. The end surface 432 of the flange 432 (shown in Figures 4-3), the protrusion 451 is completely in close contact with the end surface 432 of the cutter wheel 43, and prevents the cleaning or the moisture of the material itself from flowing into the wheel 431 during cleaning, so as to be cleaned afterwards. It's easier and extends the life of the part.

Referring to Figures 1, 2 and 3, in the present case, the feed hole 112 above the crushing chamber 11 is added to the material 70 to be cut in a tangential direction, and the material 70 can be very uniform due to moisture. The impact force is evenly distributed on the inner circumference, and may also fall on the center of the pulverizing mechanism 40 by the through hole 421 of the top plate 42. When the pulverizing mechanism 40 is rotated by the main shaft 20, the plurality of cutter wheels 43 are subjected to centrifugal force. Role and there is a tendency to pull out, but due to the cutter The upper end 4312 of the wheel 431 of the wheel 43 is pivoted with the universal joint 44 as a fulcrum, and the cutter wheel 43 is pulled outward. At this time, the lower end 4311 of the wheel 431 (as shown in FIG. 3) is along the seat 41. The guide hole 412 is thrown outward, so that the cutter wheel 43 has the energy of tapping, and the material 70 to be cut inside the stator 50 is crushed; and the cutter wheel 43 is rubbed with the stator 50 at the moment of tapping. After the pressure is extended, the material 70 to be cut can be pressed against the stator 50 to tear it; and the rotation of the cutter wheel 43 itself has a cutting force, which can cut the material 70 to be cut; The rotating body formed by the top plate 42 and the seat plate 41 forms a grinding force with the stator 50, and the raw material 70 to be cut can be ground into a fine powder, and the gravity is affected when a fine powder conforming to the preset is formed. The discharge hole 114 is formed along the lower end of the cylinder 10, and is just dropped by the funnel-shaped converging end 12 and collected.

In the cutter wheel 43 shown in Fig. 1 of the present invention, the upper end 4312 of the center wheel bar 431 is a fulcrum, and the lower end 4311 of the center wheel bar 431 is a moving end. However, in actual use, the seat disk 41 is used. The guide hole 412 and the universal joint 44 of the top plate 42 and other related structures can be completely interchanged, as shown in FIG. 6, which is a simple modification of the present invention, and has the same effect, which is a basic interchange mode, and the related art person Can be easily completed, so this case does not add more explanations, and the first Chen Ming.

Referring to FIG. 7 , another embodiment of the present invention is mainly for the transmission of the main shaft 20 of the pulverizing mechanism 40, and the lower end of the main shaft 20 is connected to the power source such as the pulley 30 and the motor. The discharge hole 114 directly below is shown in Fig. 1. In Fig. 7, the discharge hole 1140 is changed to the lower end side of the crushing chamber 11, and a discharge pipe 15 is attached to facilitate the discharge of the finished product.

Further, as shown in Figs. 6 and 7, the inner side surface 51 of the stator 50 of the present invention may be formed with a slope as needed to form a tapered container space 60 which is easy to feed between the wheel surfaces of the cutter wheel 43.

In practicing the invention, it will have the following major advantages:

1. The present invention is currently applicable to a dry and wet pulverizer design, which is fed from above the cylinder, and after being struck, cut, pressed, and ground, the powder is naturally collected downward by gravity or from the lower side. The dryer pulverizer saves energy by pumping above, which saves the energy of the air supply system and the mechanism cost of purchasing the air supply system, and saves the pipeline and related equipment of the occupied area, so the cost is even more The economy can also be adapted to small and diverse mass production, and the cost is cheaper and simpler, which is an advantage of the present invention.

2. Since the pulverizer of the present invention can be used in the wet pulverization technology, the heat generated during processing can be reduced, and the starch damage rate can be effectively reduced when used for food materials, so that the material is less likely to be destroyed or deteriorated during processing, The processing is safer and the quality is better; at the same time, whether it is a material having a high water content or a low water content, it can be used, which makes the pulverizer of the present invention applicable to a wider material, which is another advantage of the present invention.

3. When the invention is fed, the raw material to be cut is added in a tangential direction from the feed hole above the crushing chamber, and the raw material has a moisture content, so that the raw material can be evenly distributed, and the impact force is evenly distributed on the inner periphery. It is easy to automatically get caught between the cutter wheel and the stator of the pulverizing mechanism, which is more time-saving and convenient during cutting and grinding, and is another advantage of the present case.

4. Since the present invention forms a taper on the inner side surface of the stator, the cutter wheel forms a large and conical material space at the trimming position of the stator, so that the raw material is easily penetrated and screwed. Fine is another advantage of the present invention.

5. Due to the invention, when the cutter wheel rotates, the protruding portion of the shaft seal can be slightly separated from the cutter wheel end surface of the pulverizing mechanism, the heat caused by the friction is reduced, and the temperature transmitted by the cutter wheel is effectively suppressed; When the protrusion of the shaft seal is reset and attached to the end surface of the cutter wheel, the protrusion The part is completely in close contact with the cutter wheel end face of the pulverizing mechanism, and prevents the cleaning or the moisture of the material itself from flowing into the wheel bar during cleaning, which makes cleaning easy and prolongs the life of the part.

The above-mentioned structures are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention; therefore, equivalents or modifications may be made without departing from the invention. Equivalent changes and modifications made in the spirit and scope, for example, a slight change in the overall shape of the invention, or an increase or decrease in the number of parts, are all simple alternatives to the present invention and should be covered by the patent scope of the present invention.
