Description

Technical Field

[0001] The utility model relates to the field of billet cutting, and particularly to an automatic billet cutting device. Background Art

[0002] Refractory bricks are made by high-temperature roasting using advanced production processes and technologies. They have superior properties such as low density, high porosity, low thermal conductivity, good heat preservation, and certain compressive strength, and are widely used in heat treatment equipment. After rapid development in recent years, customers have higher requirements for products, and the demand for product specifications, categories, and output is increasing.

[0003] The forming methods of refractory bricks include manual ramming forming, machine pressing forming, and extrusion forming by an extruder, etc. Although the former two forming methods have the advantages of fewer processes, simplicity, and less material consumption, they have the defects that it is difficult to guarantee the finished product size and the appearance does not meet the ideal state. However, the products processed by the latter extrusion forming have delicate appearance and precise dimensions, meeting the standard requirements of customers for products. But after extrusion forming, the extruded clay strip needs to be cut, then pushed forward, and finally placed on the brick blank tray and sent into the drying room. Its processes are numerous, complex, and the production efficiency is low.

[0004] Currently, in China, most manufacturers adopt the traditional method of cutting clay strips to form billets, or introduce equipment such as strip cutting machines and billet cutting machines in the wall material and brick and tile industries for production. The former all adopt manual methods and complete the billet cutting and forming through three steps: cutting the clay strip, pushing the clay billet, and placing the clay billet. This method not only reduces the production efficiency but also increases the labor intensity, and the clay billets have instability and large differences due to manual operation. Especially for extra-long bricks, it is almost impossible to complete production by manual methods, and the types of brick blank specifications are greatly limited. The latter uses steel wires to cut a certain length of clay strip into billets of a certain specification, push them to the drying tray, and then manually carry them to the drying cart by subsequent workers. This method has great defects. The steel wires cannot be cleaned in time, which affects the billet cutting effect, and there is manual intervention, so full automation cannot be achieved, and the production efficiency is low.

[0005] The traditional method of cutting clay strips to form billets has the defects of low production efficiency, high labor intensity, and low automation degree; introducing equipment from other industries is not targeted at the production of heat-insulating refractory bricks, and still requires a large number of other equipment for assistance and manual operations, greatly increasing the production cost, affecting the quality of brick blanks, and reducing the production efficiency of customers.

[0032] See Figures 1-6 , the present utility model discloses an automatic brick cutting device, which includes a frame 1 and a brick cutting device, a conveying device, a brick pushing device and a billet feeding device installed on the frame 1.

[0033] The brick cutting device includes a brick cutting mechanism 2 and a brick cutting guiding assembly 3.

The billet feeding mechanism is used to convey the blank carrying mechanism, and the blank carrying mechanism is used to carry the brick blank 200.

[0037] The conveying mechanism of the automatic billet cutting equipment of the utility model extrudes the clay strip, enables the clay strip to move on the conveying rack, and realizes the automatic conveying of the clay strip; according to the size of the required brick blank, the billet cutting driving mechanism drives the moving seat to move on the billet cutting guiding component to drive the cutting tool mechanism to accurately reach the corresponding position, and then starts the cutting tool mechanism to cut off the clay strip and obtain the brick blank of the required size.

[0038] Preferably, the billet cutting driving mechanism 2 is a servo motor. The conveying mechanism is an extruder, and the extruder extrudes the clay strip onto the conveying rack, enabling the clay strip to move from one end of the conveying rack to the other end. The number of the billet cutting mechanisms 2 is several, and the clay strip can be cut multiple times at one time to obtain multiple brick blanks. As Figure 1 shown, the utility model is provided with 4 billet cutting mechanisms, and at most 3 brick blanks can be obtained by cutting at one time.

[0039] Specifically, as Figure 3 shown, the cutting tool mechanism includes a cutting tool driving mechanism 23 and a cutting tool 24 connected to the cutting tool driving mechanism 23. The cutting tool driving mechanism 23 drives the cutting tool 24 to move up and down to cut the clay strip. The cutting tool driving mechanism 23 is a cylinder.

[0040] More preferably, the moving seat 21 is further provided with a moving seat sensor, which can sense the position between two adjacent moving seats to prevent collision.

[0041] Preferably, as Figure 2 shown, the top of the conveying rack 4 is covered with fish scale plates 41, and the bottom is provided with an adjusting mechanism 42 for adjusting the height of the conveying rack 4. The setting of the fish scale plates can largely prevent the clay strip and the brick blank from sticking to the conveying rack, facilitating the movement of the clay strip and the brick blank on the conveying rack. The setting of the adjusting mechanism can adjust the height of the clay strip and the brick blank and the interval between the conveying rack and the billet cutting mechanism, with a wide application range.

[0042] Preferably, as Figures 1-2As shown, the blank cutting guiding assembly 3 includes a guiding beam 31, a driving wheel (not shown in the figure), and a driving strip 32. The guiding beam 31 is installed on the frame 1, the driving strip 32 is arranged on the guiding beam 31, the blank cutting driving mechanism 22 is connected to the driving wheel, and the driving wheel is meshed and connected to the driving strip 32. More preferably, the driving wheel is a gear, and the driving strip 32 is a rack. The extending direction of the driving strip 32 is the same as that of the guiding beam 31. The blank cutting driving mechanism can drive the gear to rotate, so that the moving seat can move back and forth along the driving strip, that is, the guiding beam, to adjust the position of the blank cutting mechanism, that is, the cutting knife, above the conveying rack, that is, the mud strip, so as to cut out brick blanks of the required size.

[0043] More preferably, as Figures 2-3 shown, the moving seat 21 is provided with sliding blocks 25, and the guiding beam 31 is provided with blank cutting guide rails 33. The sliding blocks 25 are slidably connected to the blank cutting guide rails 33. The cooperation between the sliding blocks and the blank cutting guide rails enables the blank cutting mechanism to move stably on the guiding beam without deviation. Specifically, the number of the sliding blocks 25 is at least two, which are respectively arranged on the top and side of the moving seat 21; the number of the blank cutting guide rails 33 is at least two, which are respectively arranged on the top and side of the guiding beam 31; the sliding blocks 25 and the blank cutting guide rails 33 are arranged in one-to-one correspondence. The arrangement of two groups of sliding blocks and blank cutting guide rails further ensures the stable movement of the blank cutting mechanism, and thus ensures the stability and reliability of cutting.

[0044] Preferably, as Figure 2 shown, limiting blocks 34 are respectively arranged at both ends of the guiding beam 31 to prevent the blank cutting mechanism from detaching from the guiding beam.

[0045] Specifically, as Figure 1 shown, a blank cutting area 43 and a blank pushing area 44 are arranged on the conveying rack 4. The blank pushing device and the blank feeding device are respectively arranged corresponding to the blank pushing area 44. The conveying mechanism extrudes the mud strip into the blank cutting area and makes the mud strip move from the blank cutting area to the blank pushing area. The blank cutting mechanism cuts the mud strip in the blank cutting area to form a brick blank, then pushes the brick blank to the blank pushing area, and then the blank cutting mechanism resets and returns to the blank cutting area to prepare for the next cutting. The blank pushing device pushes the brick blank from the conveying rack to the blank feeding device, and the blank feeding device transports the brick blank away.

[0046] Preferably, as Figure 1As shown, the blank cutting device further includes a blank cutting sensor 5 for detecting the position of the clay strip 100. The blank cutting sensor 5 is provided between the blank cutting area 43 and the blank pushing area 44. More preferably, the blank cutting sensor 5 is a photoelectric proximity switch, also known as an opposed photoelectric sensor. The clay strip moves on the conveying rack under the action of the conveying mechanism. When the clay strip moves to the sensing position of the blank cutting sensor, the blank cutting sensor sends a signal to the control system, and the control system controls the supply of air to the cutter driving mechanism, so that the cutter driving mechanism drives the cutter to move downward to cut the clay strip. Then, the blank cutting mechanism moves towards the blank pushing area, and the cutter pushes the brick blank towards the blank pushing area. The cutter driving mechanism drives the cutter to move upward, and then the blank cutting mechanism resets, that is, moves towards the blank cutting area, waiting for the next cutting. That is to say, when it is detected that the clay strip moves into the blank cutting area, the cutter acts to cut the clay strip.

[0047] Specifically, as Figure 4 shown, the blank pushing device includes a blank pushing rack 63 provided on the frame 1, a blank pushing driving mechanism 61 installed on the blank pushing rack 63, and a push plate 62 connected to the blank pushing driving mechanism 61. The blank pushing driving mechanism is provided on the frame through the blank pushing rack. The blank pushing rack plays a role in supporting the blank pushing driving mechanism to ensure its working stability. The push plate moves under the drive of the blank pushing driving mechanism.

[0048] Preferably, as Figure 4 shown, the blank pushing device further includes a push plate slide 64 connected to the blank pushing driving mechanism 61, and the push plate 62 is provided on the push plate slide 64. The blank pushing driving mechanism 61 is a servo motor. The blank pushing driving mechanism drives the push plate slide, and the push plate slide drives the push plate to move, so that the push plate pushes the brick blank on the conveying rack onto the blank feeding device. More preferably, the push plate and the push plate slide are perpendicularly connected to each other, and the push plate and the conveying rack are perpendicular to each other. Specifically, a ball screw is provided on the frame 1, a screw nut is provided on the push plate slide, the blank pushing driving mechanism is connected to the ball screw, and the ball screw is in threaded connection with the screw nut. The blank pushing driving mechanism drives the push plate slide to move back and forth through the ball screw and the screw nut, thereby driving the push plate to move back and forth.

[0049] More preferably, a blank pushing guide rail is provided on the blank pushing rack 63, a blank pushing slider is provided on the push plate slide 64, and the blank pushing slider is slidably connected to the blank pushing guide rail to ensure the stability and reliability of the movement of the push plate slide.

[0050] Further, as Figure 1 、 6As shown in the figure, the blank feeding mechanism includes a blank feeding driving mechanism 71 and a blank feeding belt 72. The blank carrying mechanism includes a tray 73. The tray 73 is placed on the blank feeding belt 72. The blank feeding driving mechanism 71 is connected to the blank feeding belt 72 to drive the tray 73 to move. The blank feeding driving mechanism 71 is a motor. The blank feeding driving mechanism drives the blank feeding belt to rotate. The tray is arranged on the blank feeding belt to drive the tray to move. The blank pushing device pushes the brick blank onto the tray, and the tray transports the brick blank away.

[0051] Preferably, as Figure 1 , 6 shown in the figure, the blank carrying mechanism further includes a positioning mechanism 74 arranged on the side of the blank feeding belt 72, a pulley seat 75 connected to the positioning mechanism 74, and a pulley 76 installed on the pulley seat 75. The positioning mechanism 74 drives the pulley 76 through the pulley seat 75 to make the pulley 76 contact the tray 73, so as to place the tray 73 at a predetermined position on the blank feeding belt 72. The number of the positioning mechanisms 74 is at least two, and they are respectively arranged on the opposite sides of the blank feeding belt 72. The positioning mechanism 74 is a cylinder. When the two positioning mechanisms act simultaneously, the tray placed on the blank feeding belt can be pushed to a predetermined position on the blank feeding belt, such as the middle position, to ensure that the brick blank can completely fall on the tray, thereby ensuring the reliability of transportation. In order to reduce the friction and impact force between the positioning mechanism and the tray, the positioning mechanism contacts the tray through a pulley.

[0052] Preferably, as Figure 1 , 6 shown in the figure, the blank carrying mechanism further includes a tray sensor 77 for detecting the position of the tray 73. The tray sensor 77 is arranged on the side of the blank feeding belt 72. The tray sensor 77 is a photoelectric eye, also known as an infrared photoelectric protector. More preferably, the tray sensor 77 is arranged above the positioning mechanism 74 and the blank feeding mechanism, specifically directly above the blank feeding belt 72. When the tray sensor detects that the tray is on the blank feeding belt, it sends a signal to the control system, and the control system controls the positioning mechanism to act, pushing the tray to a predetermined position on the blank feeding belt, without manual intervention, improving production efficiency, reducing labor intensity, and having a high degree of automation.

[0053] Furthermore, as Figure 1 shown in the figure, the present utility model further includes a cleaning device for cleaning the pushing plate 62. The cleaning device is arranged on the outer side wall of the moving seat 21. The cleaning device includes a cleaning driving mechanism 81 and a cleaning member 82. The cleaning driving mechanism 81 is connected to the cleaning member 82 to drive the cleaning member 82 to contact the pushing plate 62.

[0054] Specifically, the cleaning device is arranged on the outer side wall of the moving seat 21 of the blank cutting mechanism 2 close to the pushing plate 62. The cutter driving mechanism 23 and the cleaning driving mechanism 81 act simultaneously. During the process of the cutter 24 pushing the brick blank 200 towards the blank pushing area 44, the cleaning member 82 driven by the cleaning driving mechanism 81 to descend will contact the pushing plate 62, and can clean the mud on the pushing plate, preventing the mud from solidifying on the pushing plate and avoiding the pushing plate from sticking the mud to the brick blank and affecting the quality of the brick blank.

[0055] Preferably, the cleaning member 82 is a sponge, but not limited thereto.

[0056] The working principle of the automatic brick blank cutting equipment of the present utility model is as follows:

[0057] As Figure 1 shown, the conveying mechanism pushes the mud strip 100 from one end of the conveying frame 4 to the other end, that is, from the blank cutting area 43 to the blank pushing area 44. When the mud strip 100 reaches the detection position of the blank cutting sensor 5, the cutter driving mechanism 23 drives the cutter 24 to descend to cut the mud strip 100, and at the same time the cleaning driving mechanism 81 drives the cleaning member 82 to descend. Then, the blank cutting driving mechanism 22 drives the moving seat 21 to move towards the blank pushing area 44, and the cutter 24 pushes the brick blank 200 into the blank pushing area 44. Next, the cutter driving mechanism 23 drives the cutter 24 to rise, and at the same time the cleaning driving mechanism 81 drives the cleaning member 82 to rise. The blank cutting driving mechanism 22 drives the moving seat 21 to move towards the blank cutting area 43 to reset and wait for the next blank cutting. The blank pushing driving mechanism 61 drives the pushing plate 62 to push the brick blank 200 on the blank pushing area 44 towards the tray 73, and is transported away by the blank feeding mechanism.

[0058] In summary, the present utility model provides an automatic brick blank cutting equipment, which ensures the quality of the brick blank, improves the production efficiency, reduces the labor intensity, and has a high degree of automation.

[0059] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
