Description

Technical Field

[0001] This invention relates to the field of cotton rolling technology, and more particularly to a cotton rolling production equipment. Background Technology

[0002] Rock wool is a fireproof, energy-saving, and thermal insulation material widely used in building materials, metallurgy, petroleum, and chemical industries. Rock wool rolls are a type of rock wool product, widely used in the manufacture of rock wool roll pipes or directly as pipe insulation.

[0003] In related technologies, to save space, rock wool is usually manually rolled up before being bagged and transported to its destination. Workers then unroll the rolled wool and place it onto the insulation equipment. However, this rolling method is inefficient.

[0004] Therefore, there is an urgent need for a cotton rolling production equipment to solve the above problems. Summary of the Invention

[0005] This invention provides a production equipment for rolling rock wool, which can improve the rolling efficiency of rock wool.

[0006] In a first aspect, embodiments of the present invention provide a cotton rolling production apparatus, comprising:

[0007] The guiding device, connected to an external molding machine, is used to guide the rock wool on the molding machine to complete the collection of the rock wool;

[0008] A cooling and cutting device is connected to the outlet end of the guiding device and is used to cool and cut the rock wool delivered by the guiding device in the width direction.

[0009] A rock wool breaking device is connected to the outlet end of the cooling and cutting device and is used to break the rock wool delivered by the cooling and cutting device in the length direction.

[0010] A rolling device is connected to the outlet end of the cotton breaking device and is used to roll the rock wool supplied by the cotton breaking device to obtain rolled cotton.

[0011] A weighing device is connected to the outlet end of the winding and stacking device and is used to weigh the rolled cotton conveyed by the winding and stacking device.

[0012] In one possible design, the guiding device is connected to a first driving component, which is used to drive the guiding device to change its tilt angle relative to the horizontal plane and to drive the guiding device to move up and down.

[0013] In one possible design, the guiding device includes at least two sets of first belt conveyors, each set of first belt conveyors including an upper belt conveyor and a lower belt conveyor located below the upper belt conveyor, the upper belt conveyor and the lower belt conveyor in the same set of first belt conveyors being used to clamp and convey the rock wool.

[0014] In one possible design, a first pressure roller is provided between two adjacent sets of the first belt conveyors. The first pressure roller is used to compress the rock wool conveyed by the previous set of the first belt conveyors.

[0015] In one possible design, the cooling and slitting device includes a cooling conveyor assembly and a second belt conveyor connected in sequence. The cooling conveyor assembly is used to cool the rock wool conveyed by the guiding device, and the second belt conveyor is equipped with a cutter for slitting the rock wool conveyed by the cooling conveyor assembly in the width direction.

[0016] In one possible design, the cooling conveying assembly includes a bellows and a conveyor located above the bellows. The bellows has an internal cavity and is connected to an external negative pressure fan. The conveyor is a spaced-apart idler roller or a belt conveyor with holes.

[0017] In one possible design, the second belt conveyor is also equipped with a second pressure roller, which is located downstream of the cutter and is used to perform secondary compression on the cut rock wool.

[0018] In one possible design, the cooling and cutting device further includes a third belt conveyor connected to the outlet end of the second belt conveyor. The third belt conveyor is equipped with a third pressure roller, which is used to compress the cut rock wool three times. The pressure generated between the third pressure roller and the third belt conveyor is greater than the pressure generated between the second pressure roller and the second belt conveyor.

[0019] In one possible design, the rock wool breaking device includes at least one fourth belt conveyor, which has a higher conveying speed than the third belt conveyor when the rock wool is broken in the length direction.

[0020] In one possible design, the stacking device includes a fifth belt conveyor connected to the outlet end of the fourth belt conveyor, an inclined belt conveyor forming a V-shaped space with the fifth belt conveyor, and a fourth pressure roller and a fifth pressure roller disposed within the V-shaped space. The fourth pressure roller is located upstream of the fifth pressure roller, and the fifth pressure roller is closer to the apex of the V-shaped space relative to the fourth pressure roller. The fourth pressure roller rotates counterclockwise, and the fifth pressure roller rotates clockwise.

[0021] The weighing device is located downstream of the apex of the V-shaped space. The coiling device is connected to a second drive assembly, which is used to drive the inclined belt conveyor to rotate so that the V-shaped space opens or closes. When the V-shaped space is open, the weighing device is used to receive the coiled cotton conveyed by the fifth belt conveyor and weigh the coiled cotton.

[0022] In one possible design, the fourth pressure roller and the fifth pressure roller are an integral structure, and the stacking device is also connected to a third driving component, which is used to drive the distance between the fourth pressure roller and the fifth pressure roller relative to the vertex of the V-shaped space to change.

[0023] In one possible design, the fourth pressure roller is positioned higher than the fifth pressure roller.

[0024] As can be seen from the above scheme, by setting up a guiding device, a cooling and cutting device, a cotton cutting device, a rolling and stacking device, and a weighing device, rock wool can be automatically collected from the forming machine. The entire unit has a high degree of automation, which can improve the rolling and stacking efficiency of rock wool. Attached Figure Description

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] like Figure 1As shown, this embodiment of the invention provides a cotton rolling production equipment, which includes a guiding device 1, a cooling and cutting device 2, a cotton cutting device 3, a rolling device 4, and a weighing device 5, wherein:

[0057] The guiding device 1 is connected to the external molding machine 10 and is used to guide the rock wool 20 on the molding machine 10 to complete the collection of the rock wool 20.

[0058] The cooling and cutting device 2 is connected to the outlet end of the guiding device 1 and is used to cool and cut the rock wool 20 delivered by the guiding device 1 in the width direction.

[0059] The cotton breaking device 3 is connected to the outlet end of the cooling and cutting device 2 and is used to break the rock wool 20 delivered by the cooling and cutting device 2 in the length direction.

[0060] The rolling device 4 is connected to the outlet end of the cotton breaking device 3 and is used to roll the rock wool 20 conveyed by the cotton breaking device 3 to obtain the rolled cotton 30.

[0061] Weighing device 5 is connected to the outlet end of winding device 4 and is used to weigh the roll of cotton 30 conveyed by winding device 4.

[0062] In this embodiment, by setting up a guiding device 1, a cooling and cutting device 2, a cotton cutting device 3, a rolling and stacking device 4, and a weighing device 5, rock wool 20 can be automatically collected from the forming machine 10. The entire unit has a high degree of automation, thereby improving the rolling and stacking efficiency of rock wool.

[0063] The entire production equipment adopts a wide-area, high-speed continuous production design, with a capacity of over 5 tons of products per hour and a winding speed of over 60m / min. The surface density, length, and roll diameter of the products are adjustable.

[0064] In one embodiment of the present invention, the guide device 1 is connected to a first drive component (not shown in the figure), which is used to drive the guide device 1 to change the tilt angle relative to the horizontal plane and to drive the guide device 1 to move up and down.

[0065] In this embodiment, by setting the first driving component, the guiding device 1 can be better connected to the molding machine 10, which is beneficial to guiding the rock wool 20 on the molding machine 10 to complete the collection of the rock wool 20.

[0066] In some implementations, the first drive assembly may be a lift or gantry, equipped with limit switches, and automatically stopped at a designated position by computer control.

[0067] In one embodiment of the present invention, the guiding device 1 includes at least two sets of first belt conveyors 11, each set of first belt conveyors 11 including an upper belt conveyor 111 and a lower belt conveyor 112 located below the upper belt conveyor 111. The upper belt conveyor 111 and the lower belt conveyor 112 in the same set of first belt conveyors 11 are used to clamp and convey rock wool 20.

[0068] In this embodiment, by setting up an upper belt conveyor 111 and a lower belt conveyor 112 for clamping and conveying rock wool 20 to form a first belt conveyor 11, the problem of overturning that may occur when conveying rock wool 20 along the inclined direction when the weight is large or the inclination angle is large can be solved.

[0069] In some embodiments, the distance between the upper conveyor 111 and the lower conveyor 112 in the same first conveyor belt 11 group is adjustable, for example by means of a lift, so as to accommodate the conveying of rock wool 20 with different surface densities (i.e. different thicknesses).

[0070] In one embodiment of the present invention, a first pressure roller 12 is provided between two adjacent sets of first belt conveyors 11. The first pressure roller 12 is used to compress the rock wool 20 conveyed by the previous set of first belt conveyors 11.

[0071] In this embodiment, by setting a first pressure roller 12 between two adjacent sets of first belt conveyors 11, the rock wool 20 can be initially compressed, so that the rock wool 20 can subsequently enter the next set of first belt conveyors 11 and facilitate the cutting by the cooling and cutting device 2.

[0072] In one embodiment of the present invention, the cooling and cutting device 2 includes a cooling conveying assembly 21 and a second belt conveyor 22 connected in sequence. The cooling conveying assembly 21 is used to cool the rock wool 20 conveyed by the guiding device 1. The second belt conveyor 22 is provided with a cutter 221, which is used to cut the rock wool 20 conveyed by the cooling conveying assembly 21 in the width direction.

[0073] In this embodiment, since the rock wool 20 conveyed from the molding machine 10 is at a high temperature (around 60 degrees Celsius), it is not conducive to the storage of the subsequent rolls 30. Therefore, a cooling conveying assembly 21 is set up to cool the rock wool 20 conveyed by the guiding device 1. By setting a cutter 221 on the second belt conveyor 22, the rock wool 20 with a large width (e.g., 2.4m) can be cut, which can adapt to different production width requirements.

[0074] In some implementations, the cutter 221 can be positioned in the cutting height direction or in the width direction by using an external drive component (such as a motor or cylinder), thus adapting to different production width requirements.

[0075] In one embodiment of the present invention, the cooling conveying assembly 21 includes a wind box 211 and a conveying component located above the wind box 211. The wind box 211 has a cavity inside and is connected to an external negative pressure fan (not shown in the figure). The conveying component is a spaced roller or a belt conveyor with holes.

[0076] In this embodiment, considering that natural cooling may cause water vapor to condense in the rock wool 20, which would make the rock wool 20 damp and further cause the rolled cotton 30 to be unqualified, the inventors considered using air cooling. Furthermore, in order to ensure that the rock wool 20 does not affect its conveying process during air cooling, the inventors creatively considered using a negative pressure fan to cool the rock wool 20 on the conveyor. In order to enable the air to pass through the rock wool 20 body from above, the conveyor can be set as spaced idlers or a belt conveyor with holes.

[0077] In one embodiment of the present invention, a second pressure roller 222 is also provided on the second belt conveyor 22. The second pressure roller 222 is located downstream of the cutter 221 and is used to perform secondary compression on the cut rock wool 20.

[0078] In this embodiment, by setting a second pressure roller 222 downstream of the cutter 221, the cut rock wool 20 can be further thinned to facilitate subsequent rolling.

[0079] In one embodiment of the present invention, the cooling and cutting device 2 further includes a third belt conveyor 23, which is connected to the outlet end of the second belt conveyor 22. A third pressure roller 231 is provided on the third belt conveyor 23, which is used to squeeze the cut rock wool 20 three times. The pressure generated between the third pressure roller 231 and the third belt conveyor 23 is greater than the pressure generated between the second pressure roller 222 and the second belt conveyor 22.

[0080] In this embodiment, by setting a third pressure roller 231 on the third belt conveyor 23, the cotton breaking device 3 can be broken; at the same time, by cooperating with the second pressure roller 222 and the third pressure roller 231, the second pressure roller 222 can be used to press the rock wool 20 to provide tension when the cotton breaking device 3 changes speed, which is conducive to the breaking of the rock wool 20 and ensures a certain degree of neatness of the break.

[0081] In one embodiment of the present invention, the cotton breaking device 3 includes at least one fourth belt conveyor 31, and when the rock wool 20 is broken in the length direction, the conveying speed of the fourth belt conveyor 31 is greater than the conveying speed of the third belt conveyor 23.

[0082] In this embodiment, when it is necessary to break (or cut) the rock wool 20 along its length, the third pressure roller 231 presses down to press the rock wool 20 tightly onto the third belt conveyor 23. At this time, the fourth belt conveyor 31 immediately speeds up, thereby creating a large speed difference between the rock wool 20 between the second pressure roller 222 and the third pressure roller 231, so that this part of the rock wool 20 is quickly broken.

[0083] It is understandable that the number of the fourth belt conveyor 31 can be set according to actual needs, and no specific limit is imposed here.

[0084] In one embodiment of the present invention, the winding and stacking device 4 includes a fifth belt conveyor 41 connected to the outlet end of the fourth belt conveyor 31, an inclined belt conveyor 42 forming a V-shaped space with the fifth belt conveyor 41, and a fourth pressure roller 43 and a fifth pressure roller 44 disposed in the V-shaped space. The fourth pressure roller 43 is located upstream of the fifth pressure roller 44, and the fifth pressure roller 44 is closer to the apex of the V-shaped space than the fourth pressure roller 43. The rotation direction of the fourth pressure roller 43 is counterclockwise, and the rotation direction of the fifth pressure roller 44 is clockwise.

[0085] The weighing device 5 is located downstream of the apex of the V-shaped space. The coiling device 4 is connected to a second drive assembly (not shown in the figure). The second drive assembly is used to drive the inclined belt conveyor 42 to rotate so that the V-shaped space opens or closes. When the V-shaped space is open, the weighing device 5 is used to receive the coiled cotton 30 conveyed by the fifth belt conveyor 41 and weigh the coiled cotton 30.

[0086] In this embodiment, the fifth belt conveyor 41 is fixed, and its speed is matched with that of the fourth belt conveyor 31 at high speed to maintain a constant high speed; the inclined belt conveyor 42 and the fifth belt conveyor 41 form a V-shaped space for the rolling of rock wool 20; when rolling, the inclined belt conveyor 42 immediately runs at high speed, and when the rolling is completed, the apex of the V-shaped space can be rotated open to release the rolled cotton 30 into the groove of the weighing device 5; after the rolled cotton 30 is released, the inclined belt conveyor 42 resets and stops running to wait for the next rolling; when the rock wool 20 enters the V-shaped space, the fifth pressure roller 44 rotates at high speed, and the rock wool 20... The rock wool 20 begins to roll in the V-shaped space, adhering to the fifth pressure roller 44. As the diameter of the rolled cotton 30 gradually increases, the fifth pressure roller 44 is raised accordingly to maintain constant pressure on the outer surface of the rolled cotton 30, thereby controlling the roll diameter of the rolled cotton 30. After one rolling cycle is completed, the fifth pressure roller 44 stops rotating and resets, ready for the next rolling cycle. The fourth pressure roller 43 is linked to the fifth pressure roller 44 and rotates in the opposite direction to guide the rock wool 20 into the V-shaped space, preventing the rock wool 20 from being too thick and rolling up outside the fifth pressure roller 444, which would prevent it from entering the V-shaped space.

[0087] In one embodiment of the present invention, the fourth pressure roller 43 and the fifth pressure roller 44 are an integral structure, and the stacking device 4 is also connected to a third driving component (not shown in the figure). The third driving component is used to drive the distance between the fourth pressure roller 43 and the fifth pressure roller 44 relative to the vertex of the V-shaped space to change.

[0088] In this embodiment, considering that the rock wool 20 may escape through the gap between the fourth pressure roller 43 and the fifth pressure roller 44, the inventors creatively designed the fourth pressure roller 43 and the fifth pressure roller 44 as an integrated structure. This also helps to ensure that the fourth pressure roller 43 guides the rock wool 20 and the pressure of the fifth pressure roller 44 on the outer surface of the rolled cotton 30 remains unchanged during the rolling process.

[0089] In some implementations, the fourth pressure roller 43 is positioned higher than the fifth pressure roller 44. This not only helps prevent the rock wool 20 from being too thick and rolling up outside the fifth pressure roller 444, but also further compresses the rock wool 20 so that it can more easily enter below the fifth pressure roller 444, thereby facilitating the rolling process.
