Description

Technical Field

[0001] The utility model relates to the technical field of mugwort processing, in particular to a low-temperature soft processing wood grinding and velveting device. Background Art

[0002] Moxa is a soft and fine cotton product obtained by repeatedly drying, pounding, crushing, and sifting out impurities and dust from moxa leaves. Moxa is the raw material for making moxa sticks and is also the main material used in moxibustion.

[0003] In the process of moxa processing, a grinding device is required to grind the moxa leaves to crush them. The existing grinding device usually uses a stone roller and a stone grinding disc to grind the moxa leaves, and its production efficiency is relatively high. However, this grinding device has some defects in the actual production process due to the large weight of the stone roller itself: the stone roller will make the temperature of the moxa relatively high during the grinding process, thereby causing the effective ingredients of the moxa to volatilize and be lost, reducing the medicinal effect of the moxa; in addition, the stone roller will compact the moxa during the grinding process, making the ground moxa relatively short and the grinding effect poor.

[0007] The utility model adopts lightweight wooden rollers instead of traditional stone rollers to grind moxa leaves, which can minimize the temperature rise of the moxa wool and achieve low-temperature soft processing to the greatest extent, thereby minimizing the loss of effective ingredients in the wool making process and improving the medicinal effect of the moxa wool; and the wooden rollers are relatively gentle during the rolling process and will not compact the moxa wool, making the moxa wool more fluffy after grinding, thereby improving the grinding effect of the moxa wool.

DETAILED DESCRIPTION

[0024] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figures 1 to 5 The embodiment of the utility model provides a low-temperature soft-processed wood grinding and raising device, including a support frame 1, on which a grinding disc 2 is installed, and at least one grinding roller 3 is provided on the grinding disc 2, and the grinding roller 3 is made of wood (as long as it is wood, the present application does not limit the specific type of wood used); the outer edge of the grinding disc 2 is provided with a surrounding plate 4 (used to prevent mugwort from being squeezed out of the grinding disc 2), and a driving component 5 is provided under the grinding disc 2, and the driving component 5 is used to drive the grinding roller 3 to roll around the center of the grinding disc 2.

[0026] The utility model adopts a lightweight wooden roller 3 to replace the traditional stone roller 3 to grind the moxa leaves, which can minimize the temperature rise of the moxa wool and achieve low-temperature soft processing to the greatest extent, thereby minimizing the loss of effective ingredients in the wool making process and improving the medicinal effect of the moxa wool; and the wooden roller 3 is relatively gentle during the rolling process and will not compact the moxa wool, making the moxa wool more fluffy after grinding, thereby improving the grinding effect of the moxa wool.

[0027] Preferably, the millstone 2 and the enclosure 4 can also be made of wood. Using a wooden millstone 2 instead of a stone millstone 2 in combination with the wooden millstone 2 can further improve the grinding effect of the moxa.

[0028] In a specific embodiment, the wood used for the roller 3, the grinding disc 2, and the enclosure 4 may be wood with certain medicinal value. When the wooden roller 3 slowly rolls, grinds and rubs the mugwort leaves on the wooden grinding disc 2, the roller 3, the grinding disc 2, and the enclosure 4 themselves will also be worn. When the mugwort leaves rub against the roller 3, the grinding disc 2, and the enclosure 4, they will absorb the medicinal smell and medicinal power emitted by the wood, thereby further enhancing the medicinal effect of the moxa.

[0029] In a specific embodiment, Figure 4 As shown, the outer circumferential surface of the roller 3 is provided with a plurality of anti-skid grooves, the anti-skid grooves are opened along the axial direction of the roller 3, and the plurality of anti-skid grooves are evenly arranged along the circumference of the roller 3; the surface of the grinding disc 2 is provided with a plurality of anti-skid grooves of different lengths along the circumferential direction. By providing the anti-skid grooves on the surfaces of the roller 3 and the grinding disc 2, on the one hand, the friction force of the roller 3 rolling on the grinding disc 2 can be increased to avoid slipping; on the other hand, the grip of the roller 3 to grasp the mugwort leaves during the grinding process can also be increased, so that the mugwort leaves can be better ground and rubbed.

[0030] In a specific embodiment, a metal bottom plate (not shown in the figure) is further provided on the support frame 1, and a plurality of reinforcing ribs are provided on the bottom surface of the bottom plate. The grinding disc 2 is fixedly mounted on the top surface of the bottom plate, and a through hole for the output shaft 15 of the driving component 5 to pass through is provided in the middle of the grinding disc 2 and the bottom plate. By arranging the bottom plate on the support frame 1 to support the grinding disc 2, the force on the grinding disc 2 is more evenly distributed, and it is not easy to crack and be damaged after long-term use.

[0031] Specifically, a frame 6 is installed on the outside of the roller 3, and the two end faces of the roller 3 are rotatably connected to the frame 6 respectively. The frame 6 is connected to the driving component 5 through a transmission mechanism. The driving component 5 drives the frame 6 to rotate around the center of the grinding disc 2 through the transmission mechanism, thereby driving the roller 3 to roll around the center of the grinding disc 2.

[0032] Preferably, if Figure 3 , Figure 5 As shown, a reinforcing plate 7 (which may be a metal plate such as an iron plate or a steel plate, and preferably a circular plate) is fixedly installed on the end face of the roller 3 by a number of screws, an opening is provided at the center of the reinforcing plate 7 corresponding to the center of the roller 3, a bearing 8 is welded at the opening (one end of the bearing 8 extends into the roller 3), and a rotating shaft 9 matching the bearing 8 is provided on the inner wall of the frame 6; by installing the reinforcing plate 7 on the end face of the roller 3 and welding the bearing 8 at the opening in the middle of the reinforcing plate 7, on the one hand, the stress on the wooden roller 3 can be reduced, and on the other hand, the wooden roller 3 can be prevented from cracking after long-term use.

[0033] Furthermore, if Figure 5As shown, a connecting block 10 is provided on the outer wall of the frame 6, the rotating shaft 9 is welded to the inner wall of the connecting block 10, a through hole is opened on the frame 6 for the rotating shaft 9 to pass through, and corresponding mounting holes are provided on the connecting block 10 and the frame 6, and the connecting block 10 is fixedly mounted on the outer wall of the frame 6 by a first bolt 11; by welding the connecting block 10 on the outer wall of the frame 6 and welding the rotating shaft 9 to the inner wall of the connecting block 10, the installation and disassembly of the frame 6 and the rotating shaft 9 are facilitated, and subsequent inspection and maintenance are facilitated.

[0034] Preferably, if Figure 2 , Figure 3 As shown, the transmission mechanism includes a cross universal joint (the cross universal joint is a commonly used connecting piece in the mechanical field), and the cross universal joint includes an upper U-shaped frame 12 and a lower U-shaped frame 13. The upper U-shaped frame 12 and the lower U-shaped frame 13 are cross-rotatably connected via a cross shaft 14. The output shaft 15 of the driving component 5 passes through the grinding disc 2 and is fixedly connected to the lower U-shaped frame 13. The upper U-shaped frame 12 is fixedly connected to the frame 6. By connecting the cross universal joint between the output shaft 15 of the driving component 5 and the frame 6, the left and right tilt of the grinding roller 3 caused by the uneven thickness of the wormwood leaf on the surface of the grinding disc 2 can be automatically adapted.

[0035] Furthermore, if Figure 2 , Figure 3 As shown, a horizontal connecting plate 16 is provided on one side of the frame 6 close to the cross universal joint, and the connecting plate 16 is fixedly connected to the upper U-shaped frame 12 by a second bolt 17; flanges 18 are extended outward on both sides of the connecting plate 16, and a through hole is provided on the flange 18, and a limiting bolt 19 is inserted into the through hole, and the bottom of the limiting bolt 19 abuts against the lower U-shaped frame 13, and a nut is installed on the top of the limiting bolt 19, and the horizontal connecting line direction between the two limiting bolts 19 is consistent with the horizontal rolling direction of the roller 3. By setting two limiting bolts 19 to abut the lower U-shaped frame 13, the frame 6 can be prevented from tilting forward and backward during the rolling process of the roller 3, ensuring that the frame 6 is always in a horizontal position, thereby improving the stability of the transmission mechanism.

[0036] Preferably, if Figure 3 , Figure 4As shown, a cylindrical protective shell 20 is fixedly installed in the center of the grinding disc 2, and a gap is reserved between the outer wall of the protective shell 20 and the end face of the roller 3; the bottom opening of the protective shell 20 is provided with a flange, and the flange is connected to the grinding disc 2 by screws; the top surface of the protective shell 20 is provided with an opening for passing the output shaft 15 of the driving component 5, and an oil seal element 21 is provided at the opening (the oil seal element 21 is a sealing element commonly used in the mechanical field); by installing the protective shell 20 in the center of the grinding disc 2, on the one hand, it can be prevented that the roller 3 squeezes the mugwort to the central part of the grinding disc 2 during the grinding process of the mugwort, resulting in the mugwort in the central part of the grinding disc 2 cannot be ground by the roller 3, resulting in uneven grinding of the mugwort; on the other hand, the protective shell 20 can also play a certain protective role on the output shaft 15 of the driving component 5, preventing mugwort from entering the gap between the output shaft 15 and the grinding disc 2; in addition, by arranging the oil seal element 21 at the top opening of the protective shell 20, it can play a dustproof role.

[0037] During the specific implementation process, the number of the rolling rollers 3 can be flexibly adjusted according to actual conditions, and the present application does not make any specific limitations (the present application embodiment only shows an example with only one rolling roller 3). Multiple frames 6 can be connected around the connecting block 10, so that multiple rolling rollers 3 can be driven to roll on the grinding disc 2 at the same time through a driving component 5, thereby improving the processing efficiency of mugwort leaves.

[0038] Preferably, the driving component 5 includes a variable frequency motor and a reducer. The variable frequency motor drives the reducer motor to rotate, thereby driving the output shaft 15 to rotate. The speed of the variable frequency motor can be adjusted according to actual conditions to avoid the loss of effective ingredients due to excessive temperature of moxa.

[0039] In a specific embodiment, a support plate is provided on the support frame 1 below the grinding disc 2, and the variable frequency motor and the reducer are both installed on the support plate; and protective plates (not shown in the figure) can be provided on the four sides of the support frame 1, wherein the protective plate on at least one side is replaced by an inspection door, which is convenient for the later inspection and maintenance of the driving component 5, and can also provide a certain degree of protection for the driving component 5 during use.

[0040] Furthermore, at least one temperature sensor (not shown in the figure) is installed on the support frame 1 for detecting the ambient temperature (in the specific implementation process, the temperature sensor can also be installed in the grinding disc 2 for directly detecting the temperature of the moxa), and the temperature sensor and the variable frequency motor are respectively connected to the controller, and the controller adjusts the speed of the variable frequency motor according to the temperature data detected by the temperature sensor; when the ambient temperature is detected to be high (such as in summer), the speed of the variable frequency motor can be appropriately reduced, thereby reducing the rolling speed of the grinding roller 3, thereby reducing the temperature of the moxa and retaining the medicinal effect of the moxa to the maximum extent; when the ambient temperature is detected to be low (such as in winter), the speed of the variable frequency motor can be appropriately increased, thereby increasing the rolling speed of the grinding roller 3. Since the ambient temperature is low, the temperature of the moxa will not be very high. Under the premise of retaining the medicinal effect of the moxa, the processing efficiency can be maximized.

[0041] The working process of the velvet raising device in this embodiment is as follows:

[0042] First, the wormwood to be ground is spread on the grinding plate 2, and then the variable frequency motor is started. The variable frequency motor drives the reducer to run through the belt, and the reducer drives the output shaft 15 to rotate. The output shaft 15 drives the frame 6 to rotate around the center of the grinding plate 2 through the cross universal joint and the connecting block 10. The roller 3 rolls around the center of the grinding plate 2 under the drive of the frame 6 to grind the wormwood spread on the grinding plate 2; Due to the existence of the cross universal joint, the left and right ends of the roller 3 can float up and down within a certain range, even if the thickness of the wormwood on the grinding plate 2 is unevenly distributed, the roller 3 can also pass smoothly; After a certain period of grinding, the wormwood on the grinding plate 2 is processed into wormwood floss, and the wormwood floss on the grinding plate 2 can be collected. In this embodiment, the wooden roller 3 is driven by the variable frequency motor and the reducer to grind the wormwood on the wooden grinding plate 2, and the speed of the variable frequency motor can be adaptively adjusted according to the ambient temperature detected by the temperature sensor, so that the temperature of the wormwood is too high during the grinding process, resulting in the loss of medicinal efficacy, and truly achieving low-temperature soft processing, and retaining the medicinal efficacy of wormwood floss to the maximum extent.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
