Description

Technical Field

[0001] The present application relates to the technical field of equipment dust prevention, and in particular to an air inlet dust prevention structure. Background Art

[0002] In textile production, the dryer is one of the indispensable drying equipment, and the quality of the dryer directly affects the quality of the textiles. The drying box is provided with an air inlet, through which air is drawn into the dryer to heat it, and then the hot air is used to blow the textile surface to dry it.

[0003] However, during the operation of the drying box, external dust can easily be brought into the drying box through the air inlet, and then stick to the surface of the textiles, causing the textiles to be contaminated; and excessive dust accumulation can also cause damage to the drying box.

[0004] Based on this, the staff covered the surface of the air inlet with a filter to block the outside dust from entering the drying box. When the drying box is used for a long time, the mesh of the filter is prone to blockage, which affects the air intake effect of the air inlet. Utility Model Content

[0005] In order to maintain the air intake effect of the drying box, the present application provides an air inlet dust-proof structure.

[0006] The present application provides an air inlet dust prevention structure adopting the following technical solution:

[0010] By adopting the above technical solution, the cooperation between the butterfly bolt and the screw rod can facilitate the installation of the clamping plate on the connecting part, and the design of the butterfly bolt allows the staff to easily rotate and tighten or loosen the bolt without the aid of tools.

[0011] Optionally, the disassembly assembly includes a connecting rod, a fixed ring, a fixed block and a first spring, the connecting rod is fixed to the connecting part, and the clamping plate is provided with a connecting port for the connecting rod to pass through; the fixed ring is arranged on the connecting rod for abutting against the clamping plate, the inner wall of the fixed ring is provided with a movable groove, and the fixed block is movably installed in the movable groove; the two ends of the first spring are respectively connected to the fixed block and the inner wall of the movable groove, and the first spring remains in a compressed state; the outer wall of the connecting rod is provided with a fixed groove for the fixed block to be inserted.

[0012] By adopting the above technical solution, the installation opening and the connecting rod cooperate to cover the clamping plate on the air inlet surface, and the fixing collar is sleeved on the outer wall of the connecting rod.

[0013] Optionally, the fixing groove passes through the opposite side walls of the connecting rod, and a plug-in block is movably installed in the fixing groove; the fixing ring is provided with a plug-in groove, and when the fixing block is plugged into the fixing groove, the plug-in block is plugged into the plug-in groove; the fixing ring is provided with a ejection piece for ejecting the fixing block from the plug-in groove.

[0014] By adopting the above technical solution, when the fixed groove and the movable groove are arranged opposite to each other, the fixed block is inserted into the fixed groove by the elastic force of the first spring; at this time, the fixed block abuts against the plug-in block, and the plug-in block is pushed toward the side away from the movable groove to be plugged into the plug-in groove, thus completing the connection between the fixed collar and the connecting rod; when the fixed collar needs to be removed from the connecting rod, the push piece can be used to push the plug-in block out of the plug-in groove to return it to the fixed groove by pressing; the fixed block is pushed back into the movable groove by the plug-in block, thus unlocking the fixed sleeve and the connecting rod. This structure can cancel the plug-in of the fixed block and the fixed groove on time, which is more convenient and improves the disassembly and assembly efficiency of the staff.

[0019] Optionally, an unlocking groove is provided on the outer wall of the fixed collar, and the unlocking groove is connected to the movable groove; an unlocking rod is slidably installed in the unlocking groove, and one end of the unlocking rod is connected to the fixed block.

[0020] By adopting the above technical solution, the position of the fixed block in the movable groove can be changed by pulling the unlocking rod, so that the fixed block can be completely inserted into the movable groove, thereby improving the convenience of disassembly and assembly.

[0021] Optionally, the fixed ring includes a second spring and a first ring and a second ring installed at both ends of the second spring, and the first ring and the second ring are both sleeved on the outer wall of the connecting rod; the movable groove is opened in the first ring, the second ring is used to abut against the clamping plate, and the second spring is used to drive the second ring to move toward the side away from the first ring.

[0022] By adopting the above-mentioned technical solution, when the first ring is fixed to the connecting rod through the plug-in cooperation between the fixing block and the fixing groove, the elastic force of the second spring can make the second ring abut against the side wall of the clamping plate, so that the clamping plate can be clamped between the second ring and the connecting part, thereby reducing the possibility of the filter cotton being detached from the clamping plate and the connecting part.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting filter cotton and disassembly components, the filter cotton is clamped between the clamping plate and the connecting part. When the outside air enters the air inlet through the air inlet hole, the filter cotton can effectively filter the air entering the drying box, reducing the dust and impurities entering the drying box; the disassembly component can separate the clamping plate from the connecting part to facilitate cleaning or replacement of the filter cotton, reducing the possibility of poor air intake effect of the air inlet caused by clogging of the filter cotton due to long-term use;

[0025] 2. By setting the fixing ring as the first ring, the second ring and the second spring, the elastic force of the second spring can make the second ring abut against the side wall of the clamping plate, so that the clamping plate can be clamped between the second ring and the connecting part, reducing the possibility of the filter cotton being detached from the clamping plate and the connecting part.

[0037] When connecting the clamping plate 1 to the connecting portion 4, the filter cotton 2 is first covered on the surface of the air inlet; since the filter cotton 2 is flexible, the filter cotton 2 can move toward the side of the screw 31 and abut against the screw 31, and during the process, the filter cotton 2 forms a hole for the screw 31 to pass through, so that the filter cotton 2 covers the surface of the installation groove 41; then the installation port 12 of the clamping plate 1 is sleeved on the screw 31 to cooperate with it, so that the filter screen is clamped between the clamping plate 1 and the filter screen.

[0038] At this time, the butterfly bolt 32 is used in conjunction with the screw rod 31 to fix the clamping plate 1 in the mounting groove 41. The design of the butterfly bolt 32 allows the staff to easily rotate and tighten or loosen the bolt without the aid of tools, thereby improving the replacement efficiency of the filter cotton 2. The butterfly bolt 32 and the screw rod 31 have a simple structure and a low price, which reduces the cost of disassembling the assembly 3.
