Description

Technical Field

[0001] The utility model relates to the technical field of brick blank rolling, in particular to a brick blank rolling device with a release beam whose inclination angle is controllable and can be raised and lowered. Background Art

[0002] In the brick rolling equipment, in order to prevent the powder from expanding after being pressed into bricks, which may cause cracks and / or fissures in the bricks, the existing rolling equipment is usually equipped with an oil cylinder and a release beam, and the release beam is inclined with the conveyor belt to form a diffusion angle. The release beam applies pressure to the pressed bricks under the action of the oil cylinder, and causes the bricks to expand at a specific deformation rate through the diffusion angle. In the production process of bricks, a rolling device is usually used for pressing. The rolling device is usually driven by two high-voltage main motors that drive two grinding rollers rotating in opposite directions. The hydraulic system on the main frame then transmits the generated hydraulic pressure to the movable roller on the device through four oil cylinders. In this way, when the material passes through the high-pressure area between the two rollers, the single-particle crushing group working mode is used to fully squeeze the material, thereby quickly reducing the particle size of the material.

[0003] In the prior art, the release beam and the oil cylinder are rigidly connected, and the inclination angle of the diffusion angle cannot be changed. When pressing bricks of different thicknesses or densities, the pressure and deformation rate required to control the expansion of the bricks are different, and the release beam whose inclination angle cannot be freely controlled is difficult to control the expansion effect of bricks of different specifications. In the actual production of bricks, the roller pressing device needs to press brick products of different thicknesses, so the spacing between the upper pressing roller and the lower pressing roller in the roller pressing device needs to be adjusted to adapt to the pressing of brick products of different thicknesses. However, in order to prevent dust from flying into the construction environment during pressing production, the existing rolling device usually performs pressing in a relatively closed space. Therefore, the upper pressing roller and the lower pressing roller are in a relatively closed space. When the distance between the upper pressing roller and the lower pressing roller needs to be adjusted, due to the airtightness of the space in which the upper pressing roller and the lower pressing roller are located, the distance between the upper pressing roller and the lower pressing roller cannot be easily known from the outside. Therefore, each time the distance between the upper pressing roller and the lower pressing roller is adjusted, a certain amount of adjustment time is required, which affects the production efficiency of the brick products. Therefore, a brick rolling device with a controllable and liftable release beam inclination angle is proposed. Utility Model Content

Example

[0021] See also Figure 1-5 The utility model provides a technical solution: a brick rolling device with controllable inclination angle of release beam and liftable, comprising a frame, a lower rolling mechanism 1, an upper rolling mechanism 2, a support plate 8 and an expansion control device 500, wherein the lower rolling mechanism 1 and the upper rolling mechanism 2 are arranged on the frame from top to bottom, the lower rolling mechanism 1 comprises a lower pressing roller group and a conveyor belt 3 wound around the lower pressing roller group, a hopper 6 and a material distribution bin 7 are arranged above the feeding side of the conveyor belt 3, the hopper 6 and the material distribution bin 7 are filled with powder 300, which is an existing conventional structure, the upper rolling mechanism 2 comprises an upper pressing roller group and a compaction belt 9 wound around the upper pressing roller group, a material compaction area 100 and a material decompression area 200 are formed between the upper rolling mechanism 2 and the lower rolling mechanism 1, The material compaction area 100 and the material decompression area 200 are arranged in sequence along the conveying direction of the conveyor belt 3. The material compaction area 100 is used to press the powder 300 into a brick 400. The support plate 8 is located in the material decompression area 200 and is supported below the conveyor belt 3. The expansion control device 500 is located in the material decompression area 200 and corresponds to the top of the support plate 8. The expansion control device 500 applies pressure to the compaction belt 9 to control the expansion of the brick 400.

[0022] The frame includes an upper frame 91 and a lower frame 92 , the lower rolling mechanism 1 is arranged on the lower frame 92 , and the upper rolling mechanism 2 is arranged on the upper frame 91 .

[0023] The expansion control device 500 includes a pressure applying unit 51, an angle control unit 52 and a release beam 53. The release beam 53 is located in the material decompression area 200 and is connected to the pressure applying unit 51. The position of the release beam 53 corresponds to the position of the support plate 8. A wear-resistant rubber plate 531 is provided on the lower surface of the release beam 53. During pressing, under the action of the pressure applying unit 51, the release beam 53 applies pressure to the compacting belt 9 to control the expansion of the brick 400.

[0024] The release beam 53 has a diffusion angle for controlling the expansion deformation rate of the brick blank 400, and the angle control unit 52 is configured to adjust the inclination angle of the diffusion angle. It should be noted that the diffusion angle is the angle between the pressure surface of the release beam 53 acting on the compaction belt 9 and the forward direction of the conveyor belt 3. The diffusion angle is set to control the expansion of the brick blank 400 at a specific deformation rate. The angle control unit 52 and the pressure applying unit 51 are both hydraulic cylinders, and the telescopic ends of the hydraulic cylinders are respectively hinged to the release beam 53, and the angle is adjusted by the telescopic movement of the hydraulic cylinders.

[0025] The brick blanks 400 on the conveyor belt 3 are supported by the support plate 8, and the release beam 53 applies pressure to the compaction belt 9 to control the expansion of the brick blanks 400D. Since the angle control unit 52 can actively and artificially adjust the inclination angle of the diffusion angle, the brick blank 400 rolling equipment can provide inclination angles of diffusion angles in different ranges when pressing brick blanks 400 of different thicknesses or densities, thereby providing the pressure and deformation rate required for controlling the expansion of brick blanks 400 of different specifications, thereby improving the production application range and the yield rate, and solving the problem of cracks or uncontrollable cracks when the existing ceramic rolling equipment produces brick blanks 400 of different specifications.

[0026] In the conveying direction along the conveyor belt 3, the angle control unit 52 and the pressure applying unit 51 are connected in sequence above the release beam 53, so that the angle control unit 52 and the pressure applying unit 51 can be combined to more conveniently control the diffusion angle of the release beam 53. Of course, in the installation position, the positions of the pressure applying unit 51 and the angle control unit 52 can also be exchanged, that is: in the conveying direction along the conveyor belt 3, the pressure applying unit 51 and the angle control unit 52 are connected in sequence above the release beam 53.

[0027] It is also possible to adopt a design in which the lower pressing roller group and the upper pressing roller group include an active roller, a driven roller and multiple pressing rollers, which is not limited here; it can be understood that the pressure applying unit 51 and the angle control unit 52 are hydraulic cylinders, which are used as power sources to drive the release beam 53 to rise and fall and adjust the tilt within a small angle range. This embodiment is explained as if the pressure applying unit 51 and the angle control unit 52 are both hydraulic cylinders.

[0028] Since the angle control unit 52 is not used as a power source for providing the main pressure, the reverse thrust it carries is not large, so the angle control unit 52 can also be implemented by using some known connecting rod structures or other structures that provide rotational motion.

[0029] In this embodiment, in order to achieve controllable state of the release beam 53, both ends of the pressure applying unit 51 and the angle control unit 52 are selectively hinged to the frame and the release beam 53, respectively, so that the linkage mechanism composed of the frame, the pressure applying unit 51, the angle control unit 52 and the release beam 53 has at least two hinge points and zero degree of freedom, and the angle control unit 52 is extended and retracted to control the inclination angle of the diffusion angle of the release beam 53.

[0030] The lower rolling mechanism 1 includes a first active roller 111, a first driven roller 112 and a lower pressing roller 113, which are connected by a conveyor belt 3. The upper rolling mechanism 2 includes a second active roller 211, a second driven roller 212 and an upper pressing roller 213, which are connected by a compaction belt 9. The upper pressing roller 213 and the lower pressing roller 113 are arranged vertically, and the upper pressing roller 213 and the lower pressing roller 113 are aligned vertically.

[0031] Upper roller seats 21 are respectively provided at both ends of the upper pressure roller 213, and the upper roller seats 21 are symmetrically arranged relative to the center of the upper pressure roller 213. Lower roller seats 31 are respectively provided at both ends of the lower pressure roller 113. A telescopic member is provided between the upper roller seat 21 and the lower roller seat 31. The telescopic member is a telescopic cylinder 41. The piston rod 61 of the telescopic cylinder 41 extends into the second channel 63 of the lower roller seat 31. The telescopic member itself can be vertically telescoped to adjust the distance between the upper pressure roller 213 and the lower pressure roller 113, wherein the lower pressure roller 113 is fixed, and the upper pressure roller 213 can be raised and lowered by the telescopic member, thereby adjusting the distance between the upper pressure roller 213 and the lower pressure roller 113.

[0032] Telescopic parts are arranged between the upper roller seat 21 and the lower roller seat 31 located on the same side, so that telescopic parts are arranged between the two ends of the upper pressure roller 213 and the lower pressure roller 113. The telescopic parts on both sides can be raised and lowered synchronously, which can well control the synchronous movement between the upper pressure roller 213 and the lower pressure roller 113, and then adjust the distance between the upper pressure roller 213 and the lower pressure roller 113, thereby preventing unnecessary deviation from occurring during the adjustment of the distance.

[0033] Two telescopic members can be provided on the same side, and the two telescopic members are symmetrically arranged relative to the upper roller seat 21 or the lower roller seat 31. Since the upper pressure roller 213 itself has a certain weight, a large number of telescopic members are provided to ensure that the upper pressure roller 213 can be raised and lowered normally and safely.

[0034] The lifting device includes a second cavity 311, a lifting screw 64, a driving member 62, a first cavity 411 and a fixing nut 66. The first cavity 411 is located in the lower roller seat 31. The inner top surface of the first cavity 411 is penetrated with a first channel 65. The second cavity 311 is located in the upper roller seat 21. The first cavity 411 and the second cavity 311 are respectively provided with fixing nuts 66. The lifting screw 64 is arranged in the first channel 65, and the lifting screw 64 is threadedly connected to the fixing nut 66. The bottom of the first cavity 411 is connected to the second channel 65. 3 is connected, the lower end of the lifting screw 64 passes through the second channel 63, the outer side of the first cavity 411 is provided with a receiving notch 67, the receiving notch 67 is provided with a driving gear 68, the driving gear 68 is meshed with a driven gear 69 on the lifting screw 64, the driving member 62 is provided on the outer side of the lower roller seat 31, the driving member 62 is used to drive the lifting screw 64 to rotate, so that the lifting screw 64 is driven to rotate by the driving member 62, because the fixing nut 66 is fixed, according to the principle of thread transmission, the lifting screw 64 will be lifted and lowered vertically.

[0035] The driving member 62 is used to drive the lifting screw 64 to rotate. After the driving member 62 drives the lifting screw 64 to rise and fall to a preset position, the telescopic cylinder 41 drives the upper roller seat 21 or the lower roller seat 31 to the preset position and contacts the lifting screw 64 to adjust the distance between the upper pressure roller 213 and the lower pressure roller 113.

[0036] The driving member 62 can be specifically a motor, and the motor and the lifting screw 64 are transmitted through a transmission assembly composed of a driving gear 68 and a driven gear 69, so that the motor can drive the lifting screw 64 to rotate. Therefore, the user can control the number of circles rotated by the motor to control the number of circles rotated by the lifting screw 64, and then control the height of the lifting screw 64 rising or falling. Therefore, the user only needs to control the number of circles rotated by the motor to accurately control the spacing between the upper pressure roller 213 and the lower pressure roller 113, and can quickly adjust the spacing.

[0037] The pressure pad 70 is vertically aligned with the lifting screw 64, and the bottom surface of the pressure pad 70 is provided with ventilation blowing holes, and the blowing holes are all connected to the same ventilation channel to connect to an external hair dryer; when the upper pressure roller 213 moves downward, that is, during the process of the bottom surface of the pressure pad 70 and the bottom surface of the lifting screw 64 being re-contacted and fitted, the pressure pad 70 and the lifting screw 64 are separated during this process, and the staff can start the hair dryer to direct the gas to the blowing holes through the ventilation channel. The gas will be ejected from the bottom surface of the pressure pad 70, which can blow away the dust or foreign matter on the top surface of the lifting screw 64, thereby ensuring that the bottom surfaces of multiple pressure pads 70 are on the same plane, thereby preventing the upper pressure roller 213 from unnecessary tilting.

[0038] The staff can adjust the distance between the upper pressure roller 213 and the lower pressure roller 113 by raising the lifting screw 64 to the preset position. The specific adjustment is as follows: It should be noted that the number of turns of the lifting screw 64 will be correspondingly converted into the height of the lifting screw 64 rising or falling. Since the driving member 62 drives the lifting screw 64 to rotate, the user can control the number of turns of the lifting screw 64 by the driving member 62 to control the height of the lifting screw 64 rising or falling. After the lifting screw 64 rises to the preset position, the upper roller seat 21 is driven downward by the telescopic member until the lifting screw 64 and the upper roller seat 21 are in contact. At this time, the distance between the upper pressure roller 213 and the lower pressure roller 113 The distance adjustment is the preset thickness of the brick blank 400, and the distance between the upper pressing roller 213 and the lower pressing roller 113 is indirectly adjusted by the preset position moved by the lifting screw 64; and the telescopic part can apply a downward pulling force to the upper pressing roller 213 through the upper roller seat 21, to ensure that there is sufficient force between the upper pressing roller 213 and the lower pressing roller 113 to press the brick blank 400, thereby improving the density of the brick blank 400 and making the brick blank 400 reach the preset thickness; this can also effectively prevent the upper pressing roller 1 from moving up and down during the pressing of the brick blank 400.

[0039] The basic principle of brick blank 400 forming is that an expansion control device 500 and a lifting device are arranged between the lower rolling mechanism 1 and the upper rolling mechanism 2. The expansion control device 500 includes a pressure applying unit 51, an angle control unit 52 and a release beam 53, and has the ability to adjust the inclination angle of the diffusion angle; the lifting device includes an upper pressing roller 213, a lower pressing roller 113, a fixing nut 66, a lifting screw 64 and a driving member 62, and has the ability to adjust the distance between the upper pressing roller 213 and the lower pressing roller 113. The angle control unit 52 adopts the structure of the release beam 53, which has the function of controlling the diffusion angle of the expansion deformation rate of the brick blank 400; the lifting device is between the lower rolling mechanism 1 and the upper rolling mechanism 2. The structure can be observed from the outside and then the distance between the upper pressing roller 213 and the lower pressing roller 113 can be quickly adjusted to ensure the efficiency of the production of the brick blank 400. By combining the expansion control device 500 and the lifting device, the equipment has the ability to ensure the production efficiency of the brick blank 400, improve the density of the brick blank 400 and adapt to the production of brick blanks 400 of different specifications.
