Description

Technical Field

[0001] The utility model relates to the technical field of block cotton opening, in particular to a block cotton opening device. Background Art

[0002] Block cotton is a textile material, usually made of natural fiber (such as cotton), and its shape is rectangular or block-shaped. Block cotton is soft, has good moisture absorption, and has warmth retention. It is often used to make various textiles, such as bed sheets, quilt covers, pillowcases, etc. In addition, block cotton also has a certain sound-absorbing effect and can be used as sound insulation material or decorative material. Block cotton needs to be loosened before processing, so a block cotton opening device is needed. The "a fiber cotton opening device" disclosed in the announcement number "CN213652753U" has solved the technical disadvantage of low efficiency of manual feeding. However, in actual use, devices with similar structures still have many defects. For example, the overall structure is relatively simple, and it does not have the function of pre-loosening the cotton block before opening it, which results in the device taking a long time to completely loosen the cotton block, resulting in low efficiency of the device in opening the cotton block; at the same time, it does not have the function of extracting and purifying the dust generated during the opening of the cotton block. When the staff works in a dusty environment for a long time, it will cause lung occupational disease, which will harm the health of the staff. Therefore, it is necessary to design a cotton block opening device. Utility Model Content

[0003] The purpose of the utility model is to provide a cotton block opening device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a block cotton loosening device, comprising a conveying mechanism and a pre-loosening mechanism, a loosening mechanism, and a dust removal mechanism, wherein the conveying mechanism comprises a mounting cover, a conveying belt is rotatably mounted inside the mounting cover, a diverter plate is fixedly mounted at the central position above the conveying belt through a fixed plate, multiple sets of guide wheels are rotatably mounted on both sides of the diverter plate and the inner side of the conveying mechanism, the pre-loosening mechanism comprises a mounting frame, a fixed loosening wheel and a movable loosening wheel are rotatably mounted inside the mounting frame, and the fixed loosening wheel and the movable loosening wheel are connected by a supporting spring;

[0005] The loosening mechanism includes a loosening cover, a loosening motor is fixedly installed on one side of the loosening cover, and the output end of the loosening motor passes through the loosening cover and is fixedly installed with a loosening wheel. The dust removal mechanism includes a fixed seat, two groups of dust removal tanks are fixedly installed on the top of the fixed seat, and dust extraction fans are fixedly installed on the inner sides of the dust removal tanks. A filter element is movably installed inside the dust removal tank, and a mounting plate is fixedly installed on the top of the filter element.

[0006] A cotton block opening device using the technical solution can transfer and move the cotton block by rotating the conveyor belt, so that the device can be fed when the material is in operation, and the diverter plate can divert the cotton block when it is fed, thereby avoiding the situation where the cotton block is piled up when it is fed and affects the speed and quality of its opening and tearing, and the guide wheel can guide the cotton block from the side when it is fed, thereby reducing the friction on both sides when the cotton block is fed;

[0007] The pre-loosening mechanism is fixedly installed on the rear side of the installation cover through the installation frame, so that the cotton block fed through the conveyor belt enters between the fixed loosening wheel and the movable loosening wheel, and the support spring elastically connects the fixed loosening wheel and the movable loosening wheel, so that the cotton block can be squeezed and pre-loosened by the fixed loosening wheel and the movable loosening wheel. The pre-loosening of the cotton block facilitates the subsequent loosening mechanism of the device to perform complete loosening and tearing processing on it, and greatly shortens the time taken by the loosening mechanism to completely open and tear the cotton block, thereby increasing the efficiency of the device in opening and tearing the cotton block;

[0008] The loosening mechanism is fixedly connected to the installation cover through the loosening cover, and the loosening motor drives the loosening wheel to rotate to completely loosen and tear the cotton block entering the loosening cover. The dust removal mechanism is fixedly installed on the top of the loosening cover through the fixing seat. The dust extraction fan can extract and collect the dust generated when the device completely loosens and tears the cotton block. The dust removal tank and the internal filter element can filter and purify the extracted dust, thereby realizing the function of collecting and purifying dust when the device is operating, avoiding the pollution caused by the dust flowing into the working area during the operation of the device, and increasing the safety of the staff when working in the working area of ​​the device. The mounting plate can install and fix the filter element, and at the same time it is convenient for the staff to disassemble and replace the filter element later.

[0009] Preferably, a pre-loosening motor whose output end is connected to a fixed loosening wheel is fixedly installed below the outer side of the mounting frame. The output end of the pre-loosening motor is connected to the fixed loosening wheel, so that the fixed loosening wheel can be driven to rotate during operation by the pre-loosening motor.

[0010] Preferably, a conveying motor whose output end is connected to the conveying belt is fixedly mounted on one side of the mounting cover. The conveying motor is fixedly mounted on one side of the mounting cover, so that the conveying belt can be driven to rotate by the conveying motor.

[0011] Preferably, the feature is that the outer wall of the fixed loosening wheel is provided with pre-loosening grooves at equal distances, and the outer wall of the movable loosening wheel is fixedly provided with pre-loosening convex teeth adapted to the pre-loosening grooves. The pre-loosening grooves and the pre-loosening convex teeth increase the friction force on the surfaces of the fixed loosening wheel and the movable loosening wheel respectively, thereby improving the quality of the fixed loosening wheel and the movable loosening wheel when pre-loosening the cotton block.

[0012] Preferably, a discharge cover is fixedly installed below the back of the loosening cover, and the discharge cover can discharge the cotton blocks after being opened and torn by the loosening mechanism.

[0013] Preferably, an operating rod is fixedly mounted on the top of the mounting plate, and a gripping sleeve is fixedly mounted on the outside of the operating rod.

[0015] 1. By setting the coordination between the fixed loosening wheel, the movable loosening wheel and the supporting spring, the fixed loosening wheel and the movable loosening wheel can enter the block cotton of the device for pre-loosening by extrusion. At the same time, the supporting spring elastically connects the fixed loosening wheel and the movable loosening wheel, and can elastically extrude and loosen the block cotton, so that the block cotton can be preliminarily loosened, which is convenient for the subsequent mechanism of the device to completely loosen, scatter and tear the block cotton, greatly shortening the time taken by the subsequent mechanism to completely open and tear the block cotton, and increasing the efficiency of the device in loosening and tearing the block cotton.
