[0041] The crossbeam 2 is rotated at a certain angle on the first column 11, and the stud on the crossbeam 2 slides in the arc-shaped hole 122 of the column. After it is adjusted to a certain angle, the other end of the crossbeam 2 is fixed on the second column 12 by the nut, so that the crossbeam 2 is completely fixed on the first column 11 and the second column 12.
[0042] The top of the crossbeam 2 is provided with a handle 22 for easy rotation of the crossbeam 2, and the handle 22 spans across the crossbeam 2.
[0043] Two sprockets are distributed along the length of the crossbeam 2, one being a driving sprocket 23 and the other a driven sprocket 24, with the two sprockets located near the two ends of the crossbeam 2 respectively. The driving sprocket 23 can be driven by the trolley motor. The driving sprocket 23 and the driven sprocket 24 are connected by a transmission chain 3.
[0044] A cutting trolley 4 is slidably mounted on the crossbeam 2. In this embodiment, a guide rail extending along the length direction is provided on the crossbeam 2, and the cutting trolley 4 slides on the guide rail, allowing it to slide along the length direction of the crossbeam 2. To reduce the sliding resistance of the cutting trolley 4, rollers are provided on the cutting trolley 4, and the rollers roll on the guide rail. The cutting trolley 4 is fixed to a portion of the transmission chain 3, and the drive sprocket 23 drives the transmission chain 3, thereby moving the cutting trolley 4 on the crossbeam 2.
[0045] A cutting frame 6 is provided at the bottom of the cutting carriage 4. The cutting frame 6 is rotatably mounted at the bottom of the cutting carriage 4 and can be fixed. In this embodiment, a first turntable 41 is provided at the bottom of the cutting carriage 4, and a second turntable 61 is provided at the top of the cutting frame 6. The first turntable 41 and the second turntable 61 are rotatably connected. For example, a frustum can be provided at the rotation center of the first turntable 41, and a circular hole can be provided at the rotation center of the second turntable 61. The frustum is inserted into the circular hole, and a bearing is provided between the frustum and the circular hole to achieve horizontal rotational engagement between the first turntable 41 and the second turntable 61. The rotation plane is located on a horizontal plane. To fix the first turntable 41 and the second turntable 61, after adjusting the angle between the first turntable 41 and the second turntable 61, the first turntable 41 and the second turntable 61 are fixed with bolts and nuts. For example, a stud is set at the bottom of the first turntable 41, and an arc-shaped hole is set on the second turntable 61. The stud passes through the arc-shaped hole and can slide in the arc-shaped hole. After the second turntable 61 is adjusted to a certain position, the second turntable 61 is fixed to the first turntable 41 with nuts.
[0046] The bottom of the cutting frame 6 is hinged to an angle adjustment structure 9. The angle adjustment structure 9 is elongated and hinged to the cutting frame 6 in the middle. By swinging the angle adjustment structure 9, the height of both ends can be adjusted. The swing plane of the angle adjustment structure 9 is in a vertical plane. A dust collection hood 71 is fixedly installed at one end of the angle adjustment structure 9, and a cutter head 5 is rotatably mounted thereon. The dust collection hood 71 covers the upper part of the cutter head 5. A cutter head motor 51, which drives the cutter head 5 to rotate, is fixedly installed at the other end of the angle adjustment structure 9. The cutter head motor 51 can drive the cutter head 5 to rotate via chain drive or belt drive. The belt can be a V-belt. A protective cover is installed on the transmission device between the cutter head motor 51 and the cutter head 5 to prevent dust from entering.
[0047] Several stress relief grooves 52 are distributed around the edge of the cutter head 5, such as... Figure 5 As shown, it is used to release stress during the manufacturing process of the cutter head 5 and improve the machining quality of the cutter head 5.
[0048] In the embodiment, the chain transmission can adopt a common roller chain. With the increasingly improved manufacturing technology and process of the common roller chain, the open chain transmission becomes a transmission mode with simple structure, strong adaptability and reliable transmission. The open chain transmission is convenient to maintain, so that the utility model is greatly superior to similar products in reliability and service life.
[0049] The edge of the dust collecting hood 71 is provided with a dust collecting pipe 7 in communication with the inside of the dust collecting hood 71, and the dust collecting pipe 7 is connected with an air extraction device such as a negative pressure machine or a fan through a pipeline. The dust collecting hood 71 collects the dust generated by cutting rock wool, and the dust collecting pipe 7 is used for absorbing the dust to reduce the diffusion of particulate matter, avoid the accumulation of dust under the dust plate, and improve the working environment.
[0050] The cutting trolley 4 is provided with a sliding hole 42 extending in the vertical direction, a sliding block (not shown in the figure) is slidably arranged in the sliding hole 42, the sliding block is hingedly connected to one end of an L-shaped plate 43, the sliding block can drive the L-shaped plate 43 to slide up and down as a whole, and the L-shaped plate 43 can swing on the cutting trolley 4. The other end of the L-shaped plate 43 is hingedly connected to the other end of the angle adjusting structure 9. Since the cutting trolley 4 is hingedly connected to the cutting frame 6, the rotation planes of the two are in the horizontal plane, the angle adjusting structure 9 swings with the cutting frame 6, the swing plane is in the vertical plane, and the L-shaped plate 43 is hingedly connected to the sliding block in a spherical pair. The angle of the angle adjusting structure 9 is adjusted by adjusting the L-shaped plate 43, and then the height of the cutter head 5 is adjusted.
[0051] The sliding block is fixedly connected to the output shaft of a sliding block motor (not shown in the figure), the sliding block motor is a linear motor and is fixed on the cutting trolley 4, the sliding block motor can make the output shaft thereof perform telescopic movement to drive the sliding block to slide, so that the height of the cutter head 5 can be adjusted. During cutting, the height of the cutter head 5 is lowered to facilitate cutting, and when returning to the original position in the idle stroke, the cutter head 5 is raised.
[0052] The spraying pipe 8 is fixedly arranged on the cutting trolley 4, one end of the spraying pipe 8 is connected with a water pump through a pipeline, and the nozzle at the other end of the spraying pipe 8 faces the cutter head 5. When cutting rock wool, the spraying water is used for cooling the cutter and adsorbing dust.
[0053] In the embodiment, the cutter head 5 adopts a low-speed dust-free cutter. As shown in Figure 5 The teeth of the low-speed dust-free cutter are trapezoidal in shape and are inclined in the direction opposite to the rotation direction of the cutter head 5. The use of the low-speed dust-free cutter can greatly reduce the diffusion range of the crystal grains without reducing the cutting efficiency. At the same time, measures such as spraying water adsorption and negative pressure machine dust absorption are adopted to reduce air dust pollution. Through the control system of the utility model, the operator is away from the cutting area, and the on-line equipment and the front-line operator are protected. The cutting machine of the utility model has reduced the concentration of rock wool dust to 8-10 milligrams per cubic meter during operation.
[0054] This invention adopts a gantry structure, with the cutting carriage 4 moving and the cutter head 5 rotating, both driven by traditional chain drives. This ensures reliable transmission, strong environmental adaptability, and minimizes the impact of dust. For example, in a workshop environment with a silica concentration of 30 mg / m³, the equipment can have a service life of 5-10 years under normal operating conditions, essentially unaffected by environmental factors.
[0055] In this utility model, the adjustment and fixing structures of the crossbeam 2 and the cutting frame 6 are both purely mechanical to avoid damage in dusty environments.
[0056] This invention enables automatic cutting via a control system. The control system is communicatively connected to the carriage motor, slider motor, and cutter head motor 51. The control system can instantly change the travel speed (i.e., cutting speed) of the cutter head 5 to adapt to different plate width requirements, adjust the rotational speed of the cutter head 5 to suit its type, and adjust the position of the slider to facilitate switching between the cutting and idle return states of the cutter head 5. By setting the rotational speed of the cutter head motor 51 through the control system panel of the cutting machine, and coordinating it with the rotational speed of the carriage motor to match the type of cutter head 5, high-speed and dust-free cutting can be achieved.
[0057] The cutting machine of this utility model spans across the rock wool production line, such as... Figure 6 As shown, the crossbeam 2 of the cutting machine is adjusted so that it forms a certain angle with the center line of the rock wool production line, and the cutter head 5 is adjusted to be perpendicular to the center line of the production line. When the cutting trolley 4 is running to cut the rock wool, the cutting speed can be adjusted to be the combined speed of the production line speed and the cutting trolley speed. Figure 6 As shown, the crossbeam 2 is inclined from right to left, tilting downstream of the production line. The cutting trolley 4 moves from right to left, which can superimpose the production line speed. During cutting, the production line does not need to stop, thus increasing the cutting speed without changing the cutting speed of the cutter head 5 itself. This avoids excessive dust caused by speed mismatch and improves cutting efficiency. Adjusting the moving speed of the cutting trolley 4 to match the production line speed allows the rock wool strip 102 to be cut into rectangular finished blocks 103.
[0058] On the cutting production line of rock wool, a length measuring and releasing device 101, the cutting machine of the utility model and a longitudinal cutting machine 104 are arranged in sequence along the transportation direction of the rock wool, the length measuring and releasing device 101 is in communication connection with the control system of the cutting machine, the longitudinal cutting machine first cuts the rock wool along the longitudinal direction, then passes through the length measuring and releasing device 101, the length of the rock wool passing through is measured by the length measuring and releasing device 101, when the rock wool reaches the length to be measured, the length measuring and releasing device 101 sends a signal to the control system of the cutting machine, the cutter head 5 is started, the cutting trolley 4 is operated, the cutting process is started, and the cutting is completed until the cutting is completed. According to the length to be cut of the rock wool, the cutting speed and the idle speed ratio of the cutting trolley 4 are adjusted to match the production line speed, when the cutting trolley 4 completes the cutting once and returns to the original position, the signal of the length measuring and releasing device 101 is received, the next cutting is continued, the cutting machine can be continuously operated, and the cutting efficiency is improved.
[0059] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
