Description

Technical Field

[0001] This invention relates to the field of composite fabric production technology, specifically to an automated raw material production device for volcanic rock fabric. Background Technology

[0002] Volcanic rock fabric, as a high-performance and multifunctional material, combines the high temperature resistance and wear resistance of volcanic rock, bringing unprecedented performance improvements to textiles and is widely used in fields such as fire-fighting clothing and down jackets.

[0003] The production process of volcanic rock fabric involves grinding and processing volcanic rock raw materials. When existing grinding equipment grinds volcanic rock, due to the unique porous structure of volcanic rock, it is easy for it to adhere during the grinding process. That is, some of the volcanic rock powder will adhere to the inner wall of the grinding chamber and the grinding head, which not only reduces the grinding efficiency, but also seriously affects the grinding effect.

[0004] Therefore, the present invention proposes an automated raw material production device for volcanic rock fabric to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automated raw material production device for volcanic rock fabric to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automated raw material production device for volcanic rock fabric includes a processing cylinder, in which a grinding bucket and a rotatable grinding roller are provided. Part of the grinding roller is located in the grinding bucket and another part is located outside the grinding bucket. The grinding bucket is provided with a notch adapted to the grinding roller and the edge of the notch is in contact with the grinding roller. The processing cylinder is provided with a rotatable cleaning brush that is in extrusion contact with the part of the grinding roller located outside the grinding bucket, for cleaning volcanic rock powder adhering to the grinding roller. The raw material production device also includes a striking mechanism for striking the grinding bucket to make it vibrate.

[0007] In one alternative: the processing cylinder is provided with a rotatable first shaft and a second shaft, wherein the lower end of the first shaft is fixedly connected to a grinding roller, the lower end of the second shaft is fixedly connected to a cleaning brush, a transmission component is provided between the first shaft and the second shaft, and the processing cylinder is provided with a drive component for driving the first shaft and the second shaft to rotate synchronously.

[0008] In one alternative embodiment: the striking mechanism includes multiple rods and an equal number of electromagnets. The multiple rods are semi-enclosed in a grinding bucket shape and hinged in the processing cylinder. Each rod is fitted with a magnetic sleeve, and each rod has a striking ball at its lower end. Multiple electromagnets are arranged equidistantly in an arc in the processing cylinder, corresponding one-to-one with the magnetic sleeves on the rods. When the electromagnets are energized, they repel the magnetic sleeves.

[0009] In one alternative: the processing cylinder is provided with a bracket, the bracket is provided with an energizing button for controlling the energization of all electromagnets, an de-energizing button for controlling the de-energization of all electromagnets, and a reducer, the input end of the reducer is connected to the upper end of the first rotating shaft, and the output end of the reducer is provided with a cam that can cyclically trigger the energizing button and the de-energizing button when rotating.

[0010] In one alternative embodiment: the raw material production device further includes a cleaning mechanism for keeping the cleaning brush clean. The cleaning mechanism includes a series tube disposed in the processing cylinder and capable of reciprocating up and down, a plurality of equidistant paddles passing through the series tube, and an air pump for injecting air into the series tube. Each paddle is in semi-enclosed contact with the cleaning brush. The paddle is hollow inside. The section of the series tube located inside each paddle is provided with a first exhaust hole. The paddle is provided with second exhaust holes evenly distributed on it.

[0011] In one alternative: the radial cross-section of the series tube is non-circular and its upper end penetrates through the upper side of the processing cylinder and extends to the outside of the processing cylinder. A limiting plate is provided on the section of the series tube outside the processing cylinder. A reset spring is sleeved on the section of the series tube between the limiting plate and the processing cylinder. A turntable is provided at the upper end of the second rotating shaft. A plurality of inclined abutment plates are evenly provided on the turntable around the circumference. The inclined sides of the plurality of inclined abutment plates can alternately contact and abut against the upper end of the series tube when the turntable rotates.

[0012] In one alternative: a ball bearing is embedded at the upper end of the series tube.

[0013] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: A cleaning brush removes adhering volcanic rock powder from the portion of the grinding roller outside the grinding hopper. Each rotation of the grinding roller completes one cleaning cycle, ensuring the roller remains free of volcanic rock powder. Simultaneously, a striking mechanism vibrates the grinding hopper, preventing volcanic rock powder from adhering to the inner wall of the hopper, thus achieving high-quality and efficient grinding of volcanic rock.

Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Please see Figure 1 and Figure 2 An automated raw material production device for volcanic rock fabric includes a processing cylinder 1, in which a grinding bucket 4 and a rotatable grinding roller 2 are provided. Part of the grinding roller 2 is located in the grinding bucket 4 and another part is located outside the grinding bucket 4. The grinding bucket 4 is provided with a notch adapted to the grinding roller 2 and the edge of the notch is in contact with the grinding roller 2. The processing cylinder 1 is provided with a rotatable cleaning brush 8 that is in squeezing contact with the part of the grinding roller 2 located outside the grinding bucket 4, for cleaning the volcanic rock powder adhering to the grinding roller 2. The raw material production device also includes a striking mechanism 3 for striking the grinding bucket 4 to make it vibrate.

[0025] It should be noted that the aerogel preparation device, graphene processing device, mixing device and composite device are all existing technologies and will not be described in detail here; in addition, the processing cylinder 1 is provided with a feeding port 5 for feeding volcanic rock raw materials into the grinding hopper 4 and a discharging port for taking out the ground volcanic rock powder.

[0026] Volcanic rock raw material is fed into the grinding bucket 4, and the grinding roller 2 rotates to grind the volcanic rock raw material. The resulting volcanic rock powder falls from the lower end of the grinding bucket 4 and is stored in the processing cylinder 1. The part of the grinding roller 2 outside the grinding bucket 4 is cleaned by the cleaning brush 8 to remove the adhering volcanic rock powder. The grinding roller 2 is cleaned once for each rotation, so that the grinding roller 2 is always free of volcanic rock powder. At the same time, the grinding bucket 4 is vibrated by the striking mechanism 3. The vibration makes it impossible for volcanic rock powder to adhere to the inner wall of the grinding bucket 4, thus achieving high-quality and efficient grinding of volcanic rock.

[0027] Please refer to the figure. Figure 1 , Figure 3 and Figure 4 In one embodiment of the present invention, the processing cylinder 1 is provided with a rotatable first rotating shaft 11 and a second rotating shaft 18, wherein the lower end of the first rotating shaft 11 is fixedly connected to the grinding roller 2, and the lower end of the second rotating shaft 18 is fixedly connected to the cleaning brush 8. A transmission component 12 is provided between the first rotating shaft 11 and the second rotating shaft 18. The processing cylinder 1 is provided with a driving component 6 for driving the first rotating shaft 11 and the second rotating shaft 18 to rotate synchronously. It should be noted that the driving component 6 is a rotating device such as a motor or a geared motor in the prior art. The transmission component 12 includes a transmission structure composed of several transmission wheels, transmission chains or transmission belts. All of the above belong to existing mature technologies, so they will not be described in detail here.

[0028] In this embodiment, under the action of the transmission component 12, the first rotating shaft 11 and the second rotating shaft 18 are driven to rotate synchronously and in the same direction by the driving component 6, that is, the grinding roller 2 and the cleaning brush 8 rotate synchronously and in the same direction, so that the contact sides of the grinding roller 2 and the cleaning brush 8 are in opposite contact, so as to brush off the volcanic rock powder adhering to the grinding roller 2.

[0029] Please see Figure 1 and Figure 5 In one embodiment of the present invention, the striking mechanism 3 includes multiple hanging rods 302 and an equal number of electromagnets 303. The multiple hanging rods 302 are hinged in the processing cylinder 1 in a semi-encircling shape of the grinding bucket 4 (it should be noted that the hanging rods 302 can only deflect in the direction towards or away from the grinding bucket 4 when hinged). Each hanging rod 302 is fitted with a magnetic sleeve 304, and each hanging rod 302 has a striking ball 301 at its lower end. The multiple electromagnets 303 are arranged equidistantly in an arc in the processing cylinder 1, corresponding one-to-one with the magnetic sleeves 304 on the hanging rods 302. When the electromagnets 303 are energized, they repel the magnetic sleeves 304. The processing cylinder 1 is provided with a bracket 14, which is equipped with a power-on button 15 for controlling the power on of all electromagnets 303, a power-off button 17 for controlling the power off of all electromagnets 303, and a reducer 13. The input end of the reducer 13 is connected to the upper end of the first rotating shaft 11, and the output end of the reducer 13 is provided with a cam 16 that can cyclically trigger the power-on button 15 and the power-off button 17 when rotating.

[0030] In this embodiment, during the grinding operation, the cam 16 rotates at a constant speed. The cam 16 alternately triggers the power-on button 15 and the power-off button 17. When the power-on button 15 is triggered, all electromagnets 303 are energized and magnetized, repelling the corresponding magnetic sleeves 304. This causes the lifting rod 302 to deflect toward the grinding bucket 4 until the striking ball 301 strikes the grinding bucket 4. When the power-off button 17 is triggered, all electromagnets 303 are de-energized and demagnetized, no longer repelling the corresponding magnetic sleeves 304. The lifting rod 302 returns to a vertical state under its own weight and the gravity of the striking ball 301. This cycle is repeated, so that the grinding bucket 4 is vibrating due to the striking of multiple striking balls 301 during the grinding operation, preventing volcanic rock powder from adhering to the inner wall of the grinding bucket 4.

[0031] Please see Figure 1 , Figure 4 , Figures 6-8 In one embodiment of the present invention, the raw material production device further includes a cleaning mechanism for keeping the cleaning brush 8 clean. The cleaning mechanism includes a series pipe 9 disposed in the processing cylinder 1 and capable of reciprocating up and down, a plurality of paddles 10 arranged at equal intervals and passing through the series pipe 9, and an air pump 7 for injecting air into the series pipe 9. Each paddle 10 is in semi-enclosed contact with the cleaning brush 8. The paddle 10 is hollow inside. The section of the series pipe 9 located inside each paddle 10 is provided with a first exhaust hole 25. The paddle 10 is provided with second exhaust holes 26 evenly distributed on the paddle 10. The radial cross-section of the series pipe 9 is non-circular, and its upper end penetrates the upper side of the processing cylinder 1 and extends to the outside of the processing cylinder 1. A limiting piece 23 is provided on the pipe section of the series pipe 9 located outside the processing cylinder 1. A return spring 24 is sleeved on the pipe section of the series pipe 9 located between the limiting piece 23 and the processing cylinder 1. A turntable 19 is provided at the upper end of the second rotating shaft 18. A plurality of inclined abutment pieces 20 are evenly provided on the turntable 19 in the circumferential direction. The inclined sides of the plurality of inclined abutment pieces 20 can alternately contact and abut against the upper end of the series pipe 9 when the turntable 19 rotates.

[0032] In this embodiment, when the cleaning brush 8 rotates, the turntable 19 rotates synchronously, causing multiple inclined contact plates 20 to alternately contact and abut against the upper end of the series tube 9. With the help of the reset spring 24, the series tube 9 moves up and down reciprocally, which drives multiple paddles 10 to continuously paddle the cleaning brush 8. At the same time, air is injected into the series tube 9 through the air pump 7. The airflow entering the series tube 9 enters each paddle 10 through the first exhaust hole 25, and then exits through the second exhaust hole 26. Under the action of the paddles 10 and the airflow, the volcanic rock powder on the cleaning brush 8 is efficiently removed, keeping the cleaning brush 8 clean and ensuring the cleaning effect on the grinding roller 2.

[0033] Furthermore, in this embodiment, an air guide pipe 22 is provided between the output port of the air pump 7 and the series pipe 9, and the air guide pipe 22 is a flexible hose.

[0034] Furthermore, in this embodiment, a ball bearing 21 is embedded at the upper end of the series tube 9, so that the sliding friction between the upper end of the series tube 9 and the turntable 19 and the inclined contact piece 20 is changed to rolling friction, improving the smoothness of the drive. In addition, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This descriptive method is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
