Description
Technical Field
[0001] The utility model relates to a cross-cutting machine, in particular to a closed cross-cutting machine used in a rock wool production line. Background Art
[0002] Rock wool products use basalt, dolomite and other materials as the main raw materials. After being melted at high temperature, they are centrifuged into fibers at high speed by a centrifuge. At the same time, a certain amount of binder, dust-proof oil, water-repellent, etc. are sprayed in. They are then collected by a cotton collector and spread through a pendulum process. After that, they are folded, pre-pressed, cured and cut to form rock wool products of different specifications and uses. A cross-cutting machine is used in the cutting equipment. There are two main types of cross-cutting machines used in rock wool production lines. One is an oblique cross-cutting machine, and the other is a cross-cutting machine commonly known as a "flying saw". Both cross-cutting machines use toothed circular saw blades for cutting most of the time during production. The dust cover installed on the toothed circular saw blade cannot completely cover the toothed circular saw blade. A part of the toothed circular saw blade is exposed to the outside, so some of the fine chips sawed by the toothed circular saw blade will fly into the surrounding air. Since the cutting area of most existing cross-cutting machines is an open structure, the fine chips sawed by the toothed circular saw blade and scattered into the surrounding air cannot be recovered for a second time and spread into the production workshop, which will cause serious pollution to the production workshop over time. Even if there are very few cross-cutting machines with a closing device, there is still a problem that the closing device is not easy to open and is inconvenient to use and maintain. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a closed cross-cutting machine for a rock wool production line. The closed structure of the cross-cutting machine can effectively prevent the fine chips cut by the toothed circular saw blade from flying out of the cross-cutting machine, thereby avoiding pollution to the production workshop. At the same time, the closed structure of the cross-cutting machine is easy to open and close, which is convenient for use and maintenance.
[0004] In order to solve the above technical problems, the utility model of the closed cross-cutting machine mainly consists of two brackets, one or two baffles when needed, a crossbeam, one or two cutting trolleys, a cutting platform, two flip covers and soft curtains connected below them; the two ends of the crossbeam are respectively fixed to the upper part of the two brackets, the cutting trolley is fixed on the guide rail of the crossbeam, the cutting platform is located below the crossbeam between the two brackets, and the cutting platform is composed of a table and a box body. A linear groove for the cutting saw blade to pass through is opened on the table top, and the linear groove is connected to the box body below. The number of linear grooves is equal to the number of cutting trolleys. The position corresponds to the position of the cutting saw blade of the matching cutting trolley above. A chip suction pipe is connected to the bottom of the box. If the chips can pass through the side of one bracket facing the other bracket, a baffle needs to be installed. The two flaps are installed opposite to each other in the upper position between the two brackets. The two flaps are hinged to the two brackets above the beam. The lifting of the two flaps away from the hinge side is controlled by the lifting mechanism. A soft curtain is connected to the inner side of the lower side plate of each flap. When the two flaps fall, the soft curtain connected to them also falls. The lower inner side of the two sides of each soft curtain The surface is close to or in contact with the corresponding outer side surface of the table top. At this time, the two brackets and the required baffles, two flip covers, two soft curtains, and the cutting platform form an approximately closed cavity. Since the cross-cutting machine will produce flying chips at the cutting saw blade, dust cover, and straight groove during cutting, and all these parts are in the above-mentioned closed cavity, the flying chips generated are also in this closed cavity. As long as these flying chips cannot leave the above-mentioned closed cavity, they will not cause pollution to the production workshop. Due to the suction effect of the chip suction pipe connected to the lower box of the cutting platform and the suction effect of the dust suction pipe connected to the dust cover, the above-mentioned closed cavity is The cavity is in a negative pressure state, and the polluted air in the cavity cannot escape. The air outside the cavity can enter along the gaps between the various components that constitute the above-mentioned cavity. As the air outside the cavity enters, the polluted air in the cavity will be sucked away for the second time by the chip suction pipe connected to the cutting platform and the dust suction pipe connected to the dust hood, thereby avoiding pollution to the production workshop. Since each flap is equipped with a lifting mechanism, each flap and the soft curtain connected to its lower part can be easily raised and lowered. When it is raised, the above-mentioned closed cavity is completely open, which makes it very convenient to perform maintenance on the cross-cutting machine.
[0005] As a preferred structure of the cutting platform in the present invention, two parts of the frame extend from both ends of the cutting platform, and the two parts of the frame are respectively fixed together with the brackets at both ends. This increases the connection and fixing points of the entire mechanism of the cross-cutting machine, making the cross-cutting machine structure more solid.
[0006] As a further improvement of the present invention, if necessary, a cover plate is installed on the top of the bracket, and door panels are installed on the other three outer sides of the bracket except the outer side facing the other bracket as needed to form two cabinets. Adding two cabinets not only increases the use space of the cross-cutting machine, but also makes the cross-cutting machine more beautiful.
[0007] As a preferred structure of the soft curtain in the utility model, each soft curtain is divided into three independent soft curtains on the left, middle and right. The soft curtains on both sides are fixed in length, and the soft curtain in the middle is equipped with a lifting device. They are all fixed on the inner side of the lower side panel of the flip cover. Compared with the integral structure soft curtain, this split structure soft curtain is more reasonable and stronger.

[0015] like Figure 1 、 2As shown in Figures 3, 4, 5 and 6, the crosscutting machine of the utility model mainly consists of a left bracket 1, a left baffle 18 when needed, a right bracket 2, a right baffle 19 when needed, a crossbeam 3, a cutting trolley 4 when there is only one cutting trolley or the cutting trolleys 4 and 5 when there are two cutting trolleys, a cutting platform 6, a front flip cover 20, a rear flip cover 21, a front soft baffle 32 and a rear soft baffle 33. Whether to install the left baffle 18 and the right baffle 19 depends on the needs. If the left bracket 1 has a baffle function facing the side of the right bracket 2 and the sawdust cannot run away from this side, the left baffle 18 does not need to be installed. Otherwise, the left baffle 18 must be installed. Similarly, if the right bracket 2 has a baffle function facing the side of the left bracket 1 and the sawdust cannot run away from this side, the right baffle 19 does not need to be installed. Otherwise, A right baffle 19 needs to be installed. The cross-section of the front flap 20 and the rear flap 21 in the length direction is L-shaped. The shape of the connection between the two side panels of the front flap 20 and the rear flap 21 can be a right angle, an arc angle, or a transition angle connected by one or more small straight edges. The two ends of the beam 3 are respectively fixed to the upper part of the left bracket 1 and the right bracket 2. The cutting trolley is fixed on the guide rail of the beam 3. The cutting platform 6 is arranged below the beam 3 between the left bracket 1 and the right bracket 2. The cutting platform 6 is composed of a table top 7 and a box body 8. A straight groove for the cutting saw blade to pass through is opened on the table top 7. The straight groove is connected to the box body 8 below. When there is only one cutting trolley 4, there is only one straight groove 9. When there are two cutting trolleys 4 and 5, there are two straight grooves 9 and 10. The straight groove The position of 9 corresponds to the position of the cutting saw blade 40 on the upper cutting trolley 4, the position of the linear slot 10 corresponds to the position of the cutting saw blade 42 on the upper cutting trolley 5, and a chip suction pipe is connected to the bottom of the box body 8, which is not drawn here. The front flip cover 20 is hinged to the right bracket 2 and the left bracket 1 at positions 24 and 26 above the crossbeam 3, respectively, and the rear flip cover 21 is hinged to the right bracket 2 and the left bracket 1 at positions 25 and 27 above the crossbeam 3, respectively. The lifting mechanisms 28 and 29 control the lifting of the side of the front flip cover 20 away from the hinge, and the lifting mechanisms 30 and 31 control the lifting of the side of the rear flip cover 21 away from the hinge. The lifting mechanisms 28, 29, 30, and 31 can be cylinders or electric push rods. The lifting mechanisms of the two flip covers are not limited to the above structures and may have other structures. For example, they may be arranged below or above the flip covers, that is, they may be a single air cylinder or electric push rod or winch, or multiple air cylinders or electric push rods or winches. A front soft curtain 32 is installed on the inner side of the front lower side plate 22 of the front flip cover 20. The front soft curtain 32 and the side of the front flip cover 20 away from the hinge are lifted together. A rear soft curtain 33 is installed on the inner side of the rear lower side plate 23 of the rear flip cover 21. The rear soft curtain 33 and the side of the rear flip cover 21 away from the hinge are lifted together. It is more appropriate to use colorless and transparent soft glass plates to make the front soft curtain 32 and the rear soft curtain 33. This material is relatively flat and crisp, moderately soft and hard, and colorless and transparent.It is easy to bend and observe. When the side of the front flap 20 away from the hinge falls, that is, when the front flap 20 is closed, the front soft curtain 32 connected to the front lower side plate 22 thereof also falls, and the lower inner sides of the front left soft curtain 34 and the front right soft curtain 36 on both sides of the front soft curtain 32 are respectively adjacent to or close to the front outer sides 11 and 12 of the table 7. The bottom edge of the front middle soft curtain 35 in the middle part of the front soft curtain 32 is higher than the upper plane 47 of the rock wool board 46. When the side of the rear flap 21 away from the hinge falls, that is, when the rear flap 21 is closed, the rear soft curtain 33 connected to the rear lower side plate 23 thereof also falls, and the lower inner sides of the rear left soft curtain 37 and the rear right soft curtain 39 on both sides of the rear soft curtain 33 are respectively adjacent to the rear outer sides 13 and 14 of the table 7. Touch or approach, the bottom edge of the middle part of the rear soft curtain 33 and the rear middle soft curtain 38 should be higher than the upper plane 47 of the rock wool board 46. When the front flip cover 20 and the rear flip cover 21 fall down at the same time, that is, when they are closed at the same time, the left bracket 1, the left baffle 18 when needed, the right bracket 2, the right baffle 19 when needed, the cutting platform 6, the front flip cover 20, the front soft curtain 32, the rear flip cover 21, and the rear soft curtain 33 will together form an approximately closed cavity. On the rock wool board production line, conveyor rollers are connected on both sides of the cutting platform 6 of the cross-cutting machine. The upper surface of the conveyor rollers is at the same height as the table 7 of the cutting platform 6. The rock wool board 46 enters the table 7 of the cutting platform 6 of the cross-cutting machine along the conveyor rollers, and the cutting trolley 4 carries the falling cutting saw blade 40 or the trolley 5 carries the falling cutting saw The blade 42 saws through the rock wool board 46 from one side of the crossbeam 3 to the other side, completing the transverse cutting of the rock wool board 46. The sawdust cut off by the downward rotating side of the high-speed rotating saw blade 40 enters the box body 8 through the linear groove 9. The sawdust cut off by the downward rotating side of the high-speed rotating saw blade 42 enters the box body 8 through the linear groove 10. Most of the sawdust in the box body 8 is sucked away by the dust suction pipe connected to the bottom of the box body 8. A small amount of sawdust escapes in the form of flying dust from the parts of the linear grooves 9 or 10 that are not covered by the rock wool board 46 at both ends. A part of the sawdust cut off by the upward rotating side of the high-speed rotating saw blade 40 enters the dust suction cover 41 and is sucked away by the dust suction pipe connected to the dust suction cover 41. A part of the sawdust cut off by the upward rotating side of the high-speed rotating saw blade 42 enters the dust suction cover 43, is sucked away by the dust suction pipe connected to the dust suction hood 43. Since there are gaps between the dust suction hoods 41 and 43 and the rock wool board 46 during cutting, part of the cutting saw blades 40 and 42 is exposed to the outside, so some sawdust flies into the outside air. For most cross-cutting machines in the prior art, there is no closed cavity to recycle the above-mentioned flying chips, causing them to fly into the production workshop, which will pollute the production workshop environment. For the cross-cutting machine of the utility model, these parts where flying chips are generated are all in the above-mentioned closed cavity, and the flying chips generated are also in this closed cavity. Due to the suction effect of the chip suction pipe connected to the lower part of the box body 7 and the suction effect of the dust suction pipe connected to the dust suction hood, the above-mentioned closed cavity is in a negative pressure state.The polluted air in the cavity cannot escape, but the air outside the cavity can enter through the gaps between the various components that constitute the cavity. The air entering from outside the cavity will carry the polluted air in the cavity and be sucked away again by the chip suction pipe and the dust suction pipe, thereby completely solving the pollution problem caused to the production workshop by the cross-cutting machine during cutting. Since the closed cavity is enclosed by the unique structure of the flip cover and the soft curtain connected to it, the closed cavity can be opened and closed by raising and lowering the flip cover, and the flip cover has an automatically controlled lifting mechanism that can be controlled by one button to lift and lower the flip cover, so the opening and closing of the closed cavity can be easily achieved without the need for tedious operations such as screwing. At the same time, when the flip cover is raised, the closed cavity is completely open, and the trolley, dust cover, cutting saw blade, etc. inside are exposed to the outside, making it very convenient to perform maintenance on them.
[0016] The cutting platform 6 of the present invention can be directly fixed on the ground between the left bracket 1 and the right bracket 2, without being connected to the left bracket 1 and the right bracket 2 or being tightly fixedly connected; Figure 4 、 1 As shown in Figure 2, as a preferred structure of the cutting platform 6 in the present invention, two frames 15 and 16 extend from both ends of the cutting platform 6, and the frame 15 is fixed together with the left bracket 1, and the frame 16 is fixed together with the right bracket 2. The purpose of this is to increase the connection and fixing points of the entire structure of the cross-cutting machine, making the overall structure of the cross-cutting machine more solid.
[0017] like Figure 1 、 2 As shown in Figure 5, as a further improvement of the present invention, if necessary, a cover plate is installed on the top of the left bracket 1, and door panels are installed on the other three outer sides of the left bracket 1 except the outer side facing the right bracket 2 as needed to form a cabinet 44. If necessary, a cover plate is installed on the top of the right bracket 2, and door panels are installed on the other three outer sides of the right bracket 2 except the outer side facing the left bracket 1 as needed to form a cabinet 45. If there is already a top plate similar to a cover plate on the top of the left bracket 1 and the right bracket 2, there is no need to add a new cover plate. Similarly, if there are already side panels on the other three outer sides of the left bracket 1 and the right bracket 2 except the outer side facing the other bracket, there is no need to add a new door panel. The cabinets 44 and 45 formed increase the use space of the cross-cutting machine. For example, they can be used as an electric control cabinet and a gas control cabinet, etc., and the cross-cutting machine looks more tidy and beautiful after being sealed into cabinets compared with the original exposed left bracket 1 and right bracket 2.
[0018] like Figure 1 、 26, as a further improvement of the present invention, the front soft curtain 32 is divided into three independent soft curtains on the left, middle and right, namely the front left soft curtain 34, the front middle soft curtain 35, and the front right soft curtain 36. The front left soft curtains 34 and the front right soft curtains 36 on both sides are fixed in length, and the middle front middle soft curtain 35 is equipped with a lifting device. They are all fixed on the inner side of the front lower side plate 22 of the front flip cover 20. The rear soft curtain 33 is divided into three independent soft curtains on the left, middle and right, namely the rear left soft curtain 37, the rear middle soft curtain 38, and the rear right soft curtain 39. The rear left soft curtains on both sides are fixed in length. 37 and the rear right soft curtain 39 are fixed in length, and the middle rear soft curtain 38 is provided with a lifting device, which is fixed on the inner side of the rear lower side plate 23 of the rear flip cover 21. The lifting device can be mainly composed of a motor reducer roller, and the front middle soft curtain 35 and the rear middle soft curtain 38 are lifted and lowered by the rolling of the roller. The lifting device can also be mainly composed of an electric push rod, and the electric push rod is used to lift the soft curtain. Since the front left soft curtain 34, the front middle soft curtain 35 and the front right soft curtain 36 are three independent soft curtains, the two front left soft curtains 34 and the front right soft curtains on both sides are The upper surface of the front cover 20 can be directly fixed to the upper surface 11 and 12 of the table top 7, and the lower surface can better fit with the front outer side surfaces 11 and 12 of the table top 7, thereby reducing the air leakage area. The middle front soft curtain 35 is provided with a lifting device, and the height of its bottom edge can be easily adjusted to adapt to the height of the upper plane 47 of the rock wool board 46, thereby reducing the air leakage area. Since the rear left soft curtain 37, the rear middle soft curtain 38, and the rear right soft curtain 39 are three independent soft curtains, the upper surfaces of the two rear left soft curtains 37 and the rear right soft curtain 39 on both sides can be directly fixed to the rear cover 21, and the lower surfaces can be fixed to the upper surface 11 and 12 of the table top 7. It can better fit with the rear outer sides 13 and 14 of the table top 7, reducing the air leakage area. The middle rear soft curtain 38 is equipped with a lifting device, and the height of its bottom edge can be easily adjusted to adapt to the height of the upper plane 47 of the rock wool board 46, which also reduces the air leakage area. At the same time, the width of the middle front soft curtain 35 is shorter than the overall front soft curtain 32, and the width of the middle rear soft curtain 38 is shorter than the overall rear soft curtain 33. Correspondingly, the lifting device for raising and lowering it is also shortened, which can be easier to manufacture and fix, and the structure is more reasonable and firm.
