Description

Technical Field

[0001] The utility model relates to the technical field of metal profile processing, and particularly relates to a double-layer dust removal device. Background Art

[0002] Metal composite profiles such as titanium-aluminum composite and steel-aluminum composite are widely used in industries such as consumer electronics, new energy vehicles and robots, lithium batteries and fuel cells, photovoltaics and power, medical devices, and aerospace. To ensure the cleanliness of the composite interface of the composite profile, the base material needs to be surface dust-removed before composite forming. Currently, the method of blowing from above and below with a bamboo joint pipe is used. However, the method of blowing from above and below has secondary pollution. Blowing from one side only will cause the outer surface of the base material not to be fully covered. Moreover, the bamboo joint pipe will shake during the blowing process, resulting in the displacement of the position of the bamboo joint pipe. When starting the machine again, manual repositioning is required, which is troublesome to operate. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a double-layer dust removal device, which can avoid secondary pollution, can cover the outer surface of the base material, and does not require manual repositioning.

[0004] The technical solution of the utility model is realized as follows:

[0005] A double-layer dust removal device includes a bracket, two mounting plates, and two annular air knives. The two mounting plates are longitudinally mounted on the bracket. Through holes are provided on the mounting plates. The two annular air knives are respectively fixed on the two mounting plates. The annular air knives are arranged around the outside of the through holes. The inner holes of the annular air knives and the through holes form a passage for the base material to pass through horizontally. The blowing direction of the annular air knives is opposite to the traveling direction of the base material.

[0006] Preferably, the side of the through hole away from the annular air knife is the inlet end of the passage, and the side of the annular air knife away from the through hole is the outlet end of the passage. The base material enters from the inlet end of the passage and exits from the outlet end of the passage.

[0007] Preferably, at least one of the two mounting plates is vertically movable on the bracket.

[0008] Preferably, the bracket includes a bottom plate, guide columns, and two adjustment blocks. The guide columns are fixed on the bottom plate. The two adjustment blocks are slidably sleeved on the guide columns. The two mounting plates are respectively fixed on one side of the two adjustment blocks.

[0009] Preferably, the adjustment blocks and the annular air knives are respectively located on both sides of the mounting plate.

[0010] Preferably, a through groove penetrating the upper and lower surfaces is provided in the middle of the adjustment block. The adjustment block slides on the guide column through the through groove. A through hole communicating with the through groove is provided on the side of the adjustment block away from the mounting plate. A screw rod horizontally penetrates the adjustment block to compress the through hole, so that the adjustment block is firmly sleeved on the guide column.

[0011] Preferably, two guide posts are provided, two sliding grooves are provided on each adjustment block, each adjustment block slides on the two guide posts through the two sliding grooves, two through grooves are provided and communicate with the two sliding grooves respectively, and the screw horizontally penetrates through the two through grooves of the adjustment block.

[0012] Preferably, at least two mounting grooves are provided on the bottom plate, and the screws pass through one of the mounting grooves and are fixed to one side of the composite device.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The double-layer dust removal device includes a bracket, two mounting plates and two annular air knives. The inner holes of the two annular air knives and the through holes of the two mounting plates form two channels. The two base materials of the metal composite profile respectively pass through the two channels. The side of the through hole far away from the annular air knife is the inlet end of the channel, and the side of the annular air knife far away from the through hole is the outlet end of the channel. The base materials enter from the inlet end of the channel and leave from the outlet end of the channel. The two annular air knives form an air blowing direction opposite to the traveling direction of the two base materials to perform dust removal treatment on the periphery of the base materials passing through the channel. Since the annular air cutting air flow direction of the annular air knife is parallel to the base materials, dust and other dirt are blown to the inlet side of the channel and cannot pass through the channel, and there will be no secondary pollution to the upper and lower base materials, thus ensuring the cleanliness of the composite interface; at the same time, since the annular air flow formed by the annular air knife can completely cover the periphery of the outer surface of the base materials, the dust removal is more thorough; in addition, since the annular air knife is fixed on the mounting plate and the mounting plate is mounted on the bracket, the annular air knife will not shift after the position of the bracket is determined, and there is no need for manual repositioning, which can reduce unnecessary manual losses.

[0022] Refer to Figure 1 , a double-layer dust removal device, including a bracket 1, two mounting plates 2, and two annular air knives 3. The two mounting plates 2 are longitudinally mounted on the bracket 1. Through holes 21 are provided on the mounting plates 2. The two annular air knives 3 are respectively fixed on the two mounting plates 2. The annular air knives 3 are arranged around the outside of the through holes 21. The inner holes of the annular air knives 3 and the through holes 21 form a channel for the base material 4 to pass through horizontally. The inner holes of the two annular air knives 3 and the through holes 21 of the two mounting plates 2 form two channels. The blowing direction of the annular air knives 3 is opposite to the advancing direction of the base material 4. Among them, the base material 4 refers to the material before the metal composite profile is composite. For example, if the metal composite profile is a titanium-aluminum composite material, its base materials are titanium material and aluminum material.

[0023] The inner holes of the two annular air knives 3 and the through holes 21 of the two mounting plates 2 form two channels. The two base materials 4 of the metal composite profile respectively pass through the two channels. The side of the through hole 21 away from the annular air knife 3 is the inlet end of the channel, and the side of the annular air knife 3 away from the through hole 21 is the outlet end of the channel. The base material 4 enters from the inlet end of the channel and leaves from the outlet end of the channel. For example, Figure 1As shown, the base material 4 travels horizontally from right to left. Two annular air knives 3 form a blowing direction opposite to the traveling direction of the two base materials 4 to perform dust removal treatment on the periphery of the base material 4 passing through the channel. Since the annular air cutting airflow direction of the annular air knife 3 is parallel to the base material 4, dust and other contaminants are blown to the inlet side of the channel and cannot pass through the channel, and there will be no secondary pollution to the upper and lower base materials 4, thus ensuring the cleanliness of the composite interface. At the same time, since the annular airflow formed by the annular air knife 3 can completely cover the periphery of the outer surface of the base material 4, the dust removal is more thorough. In addition, since the annular air knife 3 is fixed on the mounting plate 2, and the mounting plate 2 is mounted on the bracket 1, the annular air knife 3 will not shift after the position of the bracket 1 is determined, and there is no need for manual repositioning, which can reduce unnecessary labor losses.

[0024] The annular air knife 3 has an air inlet, an annular cavity, an annular nozzle and a Coandă side wall. Compressed air enters the annular cavity through the air ring via the air inlet, and then throttles and sprays out at a high speed through the annular nozzle towards the inlet end direction of the channel. The airflow initially flows out at a high speed along the Coandă side wall. This airflow sprays at an oblique angle along the side wall of the air ring, so a low-pressure area will be generated at the central position on one side of the air ring. This low-pressure area will force a large amount of surrounding air to flow towards the other side of the air ring together with the high-pressure outflowing airflow. When the airflow leaves the air ring, a conical annular airflow is generated. This uniform and powerful airflow can continuously and stably blow away dust and other contaminants on the base material 4 passing through the annular air knife 3.

[0025] Preferably, at least one of the two mounting plates 2 is vertically adjustable on the bracket 1, so that the distance between the two mounting plates 2 can be adjusted, and further the distance between the two annular air knives 3 can be adjusted, and the annular air knife 3 can be adjusted according to the horizontal position of the base material 4 so that the base material 4 is at the middle position of the inner hole of the annular air knife 4. As Figure 1 shown, the upper mounting plate 2 is vertically adjustable on the bracket 1, so that the upper mounting plate 2 can move up and down relative to the lower mounting plate 2, and further adjust the position of the upper annular air knife 4. Or, the lower mounting plate 2 is vertically adjustable on the bracket 1, so that the lower mounting plate 2 can move up and down relative to the upper mounting plate 2, and further adjust the position of the lower annular air knife 4. More preferably, both mounting plates 2 are vertically adjustable on the bracket 1, and further adjust the positions of the upper and lower annular air knives 4, and the annular air knife 3 can be adjusted according to the horizontal positions of the upper and lower base materials 4 so that the base material 4 is at the middle position of the inner hole of the annular air knife 4.

[0026] Specifically, referring to Figure 1 and Figure 2, the bracket 1 includes a bottom plate 11, guide columns 12 and two adjustment blocks 13. The guide columns 12 are fixed on the bottom plate 11, and the two adjustment blocks 13 are slidably sleeved on the guide columns 12. Two mounting plates 2 are respectively fixed on one side of the two adjustment blocks 13. The adjustment block 13 can slide relative to the guide column 12. When the adjustment block 13 slides up and down, the mounting plate 2 fixed on the adjustment block 13 and the annular air knife 3 fixed on the mounting plate 2 move up and down with the adjustment block 13, so that the distance between the two annular air knives 3 is adjustable, and thus the annular air knife 3 can be adjusted according to the horizontal position of the upper and lower base materials 4 so that the base material 4 is in the middle position of the inner hole of the annular air knife 4.

[0027] Preferably, the adjustment block 13 and the annular air knife 3 are respectively located on both sides of the mounting plate 2, that is, the adjustment block 13 and the annular air knife 3 are respectively located on two surfaces of the mounting plate 2, which can prevent the adjustment block 13 and the annular air knife 3 from interfering with each other and can also reduce the volume of the mounting plate 2.

[0028] Further, see Figure 2 and Figure 3 , a chute 131 penetrating the upper and lower surfaces is provided in the middle of the adjustment block 13. The adjustment block 13 slides on the guide column 12 through the chute 131, so that the distance between the two annular air knives 3 is adjustable. In order to stabilize the adjustment block 13, a through groove 132 communicating with the chute 131 is provided on the side of the adjustment block 13 away from the mounting plate 2. A screw 14 horizontally penetrates the adjustment block 13 to compress the through groove 132, so that the adjustment block 13 is firmly sleeved on the guide column 12.

[0029] Preferably, see Figure 2 and Figure 3 , two guide columns 12 are provided, two chutes 131 are provided on each adjustment block 13, and each adjustment block 13 slides on the two guide columns 12 through the two chutes 131. Two through grooves 132 are provided, which communicate with the two chutes 131 respectively, that is, each adjustment block 13 can slide up and down relative to the two guide columns 12. The screw 14 horizontally penetrates the two through grooves 132 of the adjustment block 13 to compress the two through grooves 132, so that the adjustment block 13 is firmly sleeved on the guide column 12. The provision of two guide columns 12 and two chutes 13 and two through grooves 132 on each adjustment block 13 enables each adjustment block 13 to slide relative to the two guide columns 12 simultaneously when sliding, which can ensure the levelness of the adjustment block 13 and thus avoid the inclination of the annular air knife 3.

[0030] Preferably, see Figure 2 , at least two mounting grooves 111 are provided on the bottom plate 11. The screw 15 passes through one of the mounting grooves 111 and is fixed on one side of the composite device (not shown in the figure), so that the double-layer dust removal device can be installed on the composite device. By selecting any one of the mounting grooves 111 to fix the bottom plate 11, the double-layer dust removal device can be fixed at any position and the position adjustment of the bracket 1 is convenient.

[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
