A cutting assembly for processing rock wool boards

Abstract

This utility model relates to the field of rock wool board processing technology, and discloses a cutting assembly for rock wool board processing, including: a cutter, a shaft connected to the inner wall of the cutter, a base plate rotatably connected to the front side of the outer wall of the shaft, a motor fixedly connected to the front surface of the base plate, the output shaft of the motor fixedly connected to the shaft, a connecting rod fixedly connected to the top of the base plate, a heat dissipation unit provided above the front side of the base plate, and an auxiliary unit provided on one side of the base plate. This cutting assembly for rock wool board processing, through the cooperation of the cutter, shaft, base plate, motor, connecting rod, and heat dissipation unit, allows a small amount of heat dissipation liquid to be stored in the cutter body. The heat dissipation liquid evaporates rapidly under the heat of the cutter, absorbing heat during evaporation, thus providing a relatively efficient heat dissipation effect during cutting operations. Even when cutting batches for extended periods, the cutter is less likely to remain in a high-heat state, allowing it to maintain its original high-quality performance for a long time and ensuring efficient cutting.

Description

Technical Field

[0001] This utility model relates to the field of rock wool board processing technology, specifically a cutting component for rock wool board processing. Background Technology

[0002] Rock wool board is made primarily from natural rocks, such as basalt and dolomite, sometimes with the addition of a certain proportion of slag. These raw materials undergo pretreatment processes such as crushing and screening to ensure their particle size and composition meet production requirements. The pretreated raw materials are then fed into a cupola or electric arc furnace and melted into a liquid at high temperatures (approximately 1450℃-1500℃). The molten liquid is then passed through a four-roll centrifuge or high-pressure gas blowing method to form fibers. The centrifugal method uses high-speed rotating centrifugal rollers to throw the melt out, forming fibers; the blowing method uses high-pressure airflow to disperse the melt into fibers. The formed fibers are collected in a cotton collector by negative pressure adsorption. Simultaneously, appropriate amounts of binders, dust-proofing oils, and water-repellent agents are added to bond the fibers together, forming a cotton felt with a certain thickness and density. The cotton felt is then sent to a curing furnace, where the binder is cured at high temperatures (approximately 200℃-250℃), giving the rock wool board a stable structure and strength. After curing, the rock wool board undergoes cooling, cutting, and other processes to produce products of different specifications and sizes.

[0003] During the processing of rock wool boards, a circular saw is needed to cut them in a straight line. At present, the cutting blades in the circular saw cutting components used by processing enterprises have poor continuous and efficient heat dissipation. If the cutting time of a single batch is long, the cutting blade is prone to being in a high-heat state. Over time, this will affect the original high-quality performance of the cutting blade and lead to a decrease in cutting efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a cutting assembly for processing rock wool boards, which enables the cutter in the circular saw cutting assembly to have a more efficient heat dissipation effect. When cutting a single batch for a long time, the cutter is not prone to being in a high-heat state, which makes it easier for the cutter to maintain its original high-quality performance for a long time and ensure efficient cutting, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting assembly for processing rock wool board, comprising: a cutter, a shaft connected to the inner wall of the cutter, a base plate rotatably connected to the front side of the outer wall of the shaft, a motor fixedly connected to the front surface of the base plate, the output shaft of the motor fixedly connected to the shaft, a connecting rod fixedly connected to the top of the base plate, a heat dissipation unit provided above the front side of the base plate, and an auxiliary unit provided on one side of the base plate.

[0006] Preferably, the heat dissipation unit includes: a liquid storage tank, which is fixedly connected to the front surface of the substrate, and a screw cap is threadedly connected to the front surface of the liquid storage tank. The liquid storage tank contains heat dissipation liquid, and a bent tube is fixedly connected to the bottom end of the liquid storage tank. A portion of the bent tube penetrates the substrate and is fixedly connected to the substrate. A ring is fixedly connected to the inner wall of the bent tube, and a compression spring is fixedly connected to one side of the ring. A sleeve is fixedly connected to the end of the compression spring away from the ring. A moisture-wicking block is provided on the inner wall of the sleeve, and a fastener is inserted into the outer wall of the sleeve. A rubber ring is fixedly fitted onto the outer wall of the sleeve, and the rubber ring abuts against the inner wall of the bent tube.

[0007] Preferably, a pair of crossbars are fixed to the surface of the sleeve facing the annulus, a portion of the crossbars passing through the annulus, and the outer wall of the crossbars is clearance-fitted with the through surface of the annulus.

[0008] Preferably, an observation window is embedded and fixed to the front surface of the liquid storage tank.

[0009] Preferably, the auxiliary unit includes: a mounting plate, the mounting plate being fixed to one side of the substrate, a support plate being fixed to one side surface of the mounting plate, a scraper being provided on the surface of the support plate facing the cutter, a skeleton being fixed inside the scraper, and the scraper being in contact with the blade of the cutter.

[0010] Preferably, a plurality of screws are inserted into the front surface of the support plate, and the screws sequentially pass through a portion of the support plate and the scraper and are threadedly connected to the skeleton.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This cutting component for processing rock wool boards has the following advantages over traditional technology: Through the cooperation of the cutter, shaft, base plate, motor, connecting rod, and heat dissipation unit, the connecting rod is first fixedly connected to the transmission rod of the movable cutter in the external drive device. Starting the motor causes the shaft and cutter to rotate at high speed. The external drive device drives the connecting rod, causing the rotating cutter to contact the rock wool board, thus performing the cutting operation. During this process, some of the heat dissipation liquid in the storage tank will permeate into the interior of the moisture-wicking block through the bend pipe. The moisture-wicking block is in a moist state and will contact the blade of the rotating cutter, allowing a small amount of heat dissipation liquid to remain on the blade. The heat dissipation liquid will evaporate quickly due to the heat of the cutter. During the evaporation process, it can absorb heat, which can make the cutter have a relatively efficient heat dissipation effect during operation. When cutting a batch for a long time, the cutter is not prone to being in a high-heat state, which helps the cutter maintain its original high-quality performance for a long time and ensures efficient cutting.

[0012] Through the cooperation between the cutter, shaft, base plate, motor, connecting rod, heat dissipation unit and auxiliary unit, the small amount of heat dissipation liquid on the surface of the cutter body will inevitably stick to a small amount of fine debris generated during cutting. Because the scraper is in contact with the cutter body, it can scrape off and collect the sticky fine debris, so that the cutter body is kept in a clean state. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-7This utility model provides a technical solution: a cutting assembly for processing rock wool board, including: a cutter 1, a shaft 2 connected to the inner wall of the cutter 1, a base plate 3 rotatably connected to the front side of the outer wall of the shaft 2, a motor 4 fixedly connected to the front surface of the base plate 3, the output shaft of the motor 4 fixedly connected to the shaft 2, a connecting rod 5 fixedly connected to the top of the base plate 3, a heat dissipation unit provided on the upper front side of the base plate 3, and an auxiliary unit provided on one side of the base plate 3.

[0018] In the specific implementation process, it is worth noting that the cutter 1 is made of stainless steel, which is a widely used stainless steel material containing more than 18% chromium and more than 8% nickel. Chromium can form a dense chromium oxide protective film on the surface of the steel, preventing oxygen and moisture from further corroding the steel, thus playing a role in rust prevention. The inner wall of the cutter 1 is provided with a keyway, which can be connected to the shaft 2 with a convex key. The shaft 2 is rotatably connected to the base plate 3 through a sealed bearing. The housing of the motor 4 is fixedly connected to the base plate 3. The power cord of the motor 4 is connected to an external power supply device to provide the necessary power for its operation. The connecting rod 5 is used to connect to the transmission rod of the movable cutter 1 in the external drive device.

[0019] Furthermore, the heat dissipation unit includes: a liquid storage tank 6, which is fixedly attached to the front surface of the substrate 3. A screw cap 7 is threadedly connected to the front surface of the liquid storage tank 6. The liquid storage tank 6 contains heat dissipation liquid 8. A bent tube 9 is fixedly attached to the bottom end of the liquid storage tank 6. A portion of the bent tube 9 passes through the substrate 3 and is fixedly connected to the substrate 3. A ring 10 is fixedly attached to the inner wall of the bent tube 9. A compression spring 11 is fixedly attached to one side of the ring 10. A sleeve 12 is fixedly attached to the end of the compression spring 11 away from the ring 10. A moisture-guiding block 13 is provided on the inner wall of the sleeve 12. A fastener 14 is inserted into the outer wall of the sleeve 12. A rubber ring 15 is fixedly fitted onto the outer wall of the sleeve 12. The rubber ring 15 abuts against the inner wall of the bent tube 9.

[0020] In the specific implementation process, it is worth noting that after the cap 7 is rotated counterclockwise to separate from the liquid storage tank 6, an opening will be generated on the front surface of the liquid storage tank 6, which can be used to inject the coolant 8 into the liquid storage tank 6. The coolant 8 is mainly composed of water, mineral oil, emulsifier, rust inhibitor, extreme pressure additive, etc. Water, as the main component, has good heat dissipation performance and can quickly remove the heat generated by the tool body and workpiece. Mineral oil plays a lubricating role and reduces the friction between the tool and the workpiece. The emulsifier makes the oil and water mix evenly to form a stable emulsion. The rust inhibitor prevents the tool body and workpiece from rusting. The extreme pressure additive forms a protective film under high pressure and high temperature conditions, improving the extreme pressure performance of the coolant. The bent tube 9 is interconnected with the interior of the liquid storage tank 6. The moisture absorption of the compression spring 11 is 0.2N-0.5N / CM. The moisture-wicking block 13 is a high-density polyurethane sponge with a dense and uniform microporous structure. These micropores are small in size and can adsorb and retain water in the pores through capillary action. Capillary action is a phenomenon in which a liquid rises or permeates in a narrow channel or pore due to surface tension and the adhesive force between the liquid and the pore wall. Although it can absorb water, due to the size and distribution of the pores and the high density of the sponge, the water will not easily pass through the sponge in the form of free dripping. Instead, it will form a relatively stable water-containing state inside the sponge. It is often used in some situations where water needs to be absorbed but water cannot be allowed to drip freely, such as cleaning sponges for certain precision instruments. It can absorb the water generated during the cleaning process and prevent water from dripping into the instrument and causing damage. The fastener 14 is composed of a bolt and a nut. The bolt passes through the sleeve 12 and the moisture-guiding block 13 in sequence, and the nut connected by the thread on the outer wall of the bolt abuts against the sleeve 12, which can realize the connection between the moisture-guiding block 13 and the sleeve 12. The moisture-guiding block 13 can be disassembled and replaced. The end face of the moisture-guiding block 13 away from the bend 9 is in contact with the cutter 1. The rubber ring 15 is made of rubber and has a certain degree of flexibility.

[0021] Furthermore, a pair of crossbars 16 are fixed to the surface of the sleeve 12 near the ring 10, a portion of the crossbars 16 penetrates the ring 10, and the outer wall of the crossbars 16 is clearance-fitted with the penetration surface of the ring 10.

[0022] In the specific implementation process, it is worth noting that clearance fit refers to a fit with a gap (including a minimum gap of zero), which can improve the stability of the sleeve 12 and the moisture-wicking block 13 during lateral movement.

[0023] Furthermore, an observation window 17 is embedded and fixed to the front surface of the liquid storage tank 6.

[0024] In the specific implementation process, it is worth noting that the observation window 17 is made of transparent rigid PVC material, which makes it easy for external staff to know the remaining amount of heat dissipation liquid 8 in the liquid storage tank 6.

[0025] Furthermore, the auxiliary unit includes: a mounting plate 18, which is fixedly attached to one side of the substrate 3. A support plate 19 is fixedly attached to one side surface of the mounting plate 18. A scraper 20 is provided on the surface of the support plate 19 facing the cutter 1. A frame 21 is fixedly attached inside the scraper 20. The scraper 20 is in contact with the blade of the cutter 1.

[0026] In the specific implementation process, it is worth noting that the scraper 20 is made of rubber and has a certain degree of flexibility, while the frame 21 is made of hard plastic and can provide support for the scraper 20. The scraper 20 can scrape off and collect the small amount of fine debris stuck to the blade 1, so that the blade of the cutter 1 is kept in a clean state.

[0027] Furthermore, a plurality of screws 22 are inserted into the front surface of the support plate 19, and the screws 22 pass through a portion of the support plate 19 and the scraper 20 in sequence and are threadedly connected to the frame 21.

[0028] In the specific implementation process, it is worth noting that the screw 22 can be rotated counterclockwise to remove the scraper 20 from the support plate 19, so that the fine debris collected in the scraper 20 can be thoroughly cleaned.

[0029] Working principle: Cutting operation of rock wool board: First, fix the connecting rod 5 to the transmission rod of the movable cutter 1 in the external drive device. Start the motor 4 to make the shaft 2 and the cutter 1 rotate at high speed. Drive the connecting rod 5 through the external drive device so that the cutter 1 in the rotating state contacts the rock wool board, and then the rock wool board can be cut. Cooling operation of the cutter during cutting: During the cutting operation, part of the cooling liquid 8 in the liquid storage tank 6 will seep into the interior of the moisture-wicking block 13 through the bend 9. The moisture-wicking block 13 will be in a wet state and will come into contact with the blade of the cutter 1 in the rotating state. This will allow a small amount of cooling liquid 8 to remain on the blade of the cutter 1. The cooling liquid 8 will evaporate quickly under the heat of the cutter 1. During the evaporation, it can absorb heat, which can make the cutter 1 have a relatively efficient heat dissipation effect during operation. When cutting a single batch for a long time, the cutter 1 is not easy to be in a high-heat state, which makes it easier for the cutter 1 to maintain its original high-quality performance for a long time and ensure efficient cutting. Cleaning and collecting of fine debris on the surface of the cutter body: The small amount of heat dissipation liquid 8 on the surface of the cutter body 1 will inevitably stick to a small amount of fine debris generated during cutting. Since the scraper 20 is in contact with the cutter body 1, it can scrape off and collect the sticky fine debris, so that the cutter body 1 is kept in a clean state. Subsequent maintenance: After the cutting operation is completed and the motor 4 stops running, the user can turn the screw 22 counterclockwise to remove the scraper 20 from the support plate 19, so as to thoroughly clean the fine debris collected in the scraper 20. After cleaning, the scraper 20 is reset and the screw 22 is used to install the scraper 20 and the support plate 19.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
