Description

Technical Field

[0001] This invention relates to the field of fabric keel, and in particular to a fabric keel separation mechanism and a fabric keel separation and recycling device. Background Technology

[0002] During the operation of a dust collector, factors such as the selection of filter media for the dust collector bags, the temperature of the flue gas in the working environment, and the oxygen content of the flue gas will greatly affect the actual service life of the filter bags. Therefore, it is necessary to replace the filter bag keel regularly and separate and recycle the old filter bag keel.

[0003] Currently, the international standard for separating fabric bag keels is manual. For fabric bag keels operating in good environments, after disassembly, simply fixing one end of the keel allows for easy separation of the fabric bag from the keel by pulling. However, for fabric bag keels operating in harsh environments (damp or oily), after prolonged use, the fabric bag may stick to the keel, causing it to become caked. In this case, pulling alone is insufficient to separate the fabric bag from the keel, and manual cutting is the only option, resulting in extremely low work efficiency. Summary of the Invention

[0030] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0031] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention. It should be noted that in this invention, "front" and "rear" refer to the forward direction of the bag keel, meaning the bag keel is always being transported from back to front.

[0032] like Figures 1-11As shown, an embodiment of a bag keel separation mechanism 100 includes a separation frame 110, a conveying section located on the separation frame 110, and a cutting blade 130. The conveying section includes a conveying roller 1220 drive assembly 1210, conveying rollers 1220, and at least one pressing roller 1221. At least two conveying rollers 1220 are provided, and at least one conveying roller 1220 is provided on each of the lower or upper sides of the pressing roller 1221. During operation, the cutting blade 130 abuts against the bag keel 500 located between the conveying rollers 1220 and the pressing rollers 1221 to cut the bags on the bag keel 500.

[0033] When the bag keel separating mechanism 100 is working, the bag keel 500, which is sleeved on the bag keel, is continuously conveyed forward under the drive of the conveying roller 1220. The bag keel 500 located between the two conveying rollers 1220 is taut due to the pressure of the upper pressing roller 1221, allowing the cutting blade 130 to cut the bag on the bag keel 500 in this area along its length. As the bag keel 500 continues to be conveyed forward, the entire bag on the bag keel 500 is cut open along its length. Preferably, for ease of cutting, in this embodiment, the cutting blade 130 and the pressing roller are arranged vertically in correspondence. The conveying roller 1220 drive assembly 1210 includes a conveying roller 1220 drive motor and a gear mechanism connecting the output shaft of the conveying roller 1220 drive motor and the conveying roller 1220.

[0034] In order to ensure that the bag keel 500 located between the conveying rollers 1220 is always taut, the pressing roller 1221 is provided with a position adjusting bolt 1222 for adjusting the relative position of the conveying roller 1220 and the pressing roller 1221.

[0035] The separator frame 110 includes two conveying sections arranged sequentially along the conveying direction of the fabric bag keel 500, namely, the first conveying section 1200 and the second conveying section 1201. During operation, the linear velocity of the conveying rollers in the first conveying section 1200 is greater than the linear velocity of the conveying rollers in the second conveying section 1201. Since the fabric bag keel 500 may bend after prolonged use, the greater conveying speed of the first conveying section 1200 during transport allows for the stretching of the fabric bag keel 500, thereby correcting any bending.

[0036] To ensure that the cutting blade 130 always presses against the bag on the conveying bag support 500, this embodiment also provides a spring bracket 131 on the separating frame 110. The cutting blade 130 is mounted on the spring bracket 131 and between the two conveying rollers 1220, with the cutting edge of the cutting blade 130 arranged along the conveying direction of the bag support 500. When the spring on the spring bracket 131 is in its natural state, that is, in its non-extended state, the cutting edge of the blade extends into the space occupied by the conveying trajectory of the bag support 500. Therefore, when the bag support 500 enters the space occupied by the blade extending into the conveying trajectory, the spring bracket 131 is compressed, causing the blade to press tightly against the bag on the bag support 500.

[0037] A bag keel separation and recycling device of the present invention includes a bag recycling mechanism 200 for rolling up the bag, a keel compression and recycling mechanism 300 for compressing the keel, and a bag keel separation mechanism 100 of the previous embodiment; the bag keel separation mechanism 100, the bag recycling mechanism 200 and the keel compression and recycling mechanism 300 are arranged in a straight line.

[0038] This bag keel separation and recycling device realizes the entire process of separating the bag from the bag keel, recycling the bag, and squeezing the keel by setting up a bag keel separation mechanism 100, a bag recycling mechanism 200, and a keel squeezing and recycling mechanism 300. It is convenient and simple, reduces labor costs, improves the processing efficiency of the bag keel 500, and saves maintenance time.

[0039] The bag fixing part includes a bag winding rod 230 for fixing the bag, and the output shaft of the drive motor is connected to the bag winding rod 230. After the bag cut on the bag frame 500 is fixed on the bag winding rod 230 on the bag winding machine, the drive motor starts, and the bag winding rod 230 continuously winds the bag, causing the bag on the frame to be continuously peeled off. Due to the large friction between the bag and the bag frame 500, the bag frame 500 is also continuously driven forward during the process of the bag being peeled off.

[0040] Preferably, the bag winding rod 230 includes a first bag winding rod 231 and a second bag winding rod 232 that can be connected and separated from each other. The first bag winding rod 231 is provided with a first bag fixing end 2311, and the second bag winding rod 232 is provided with a second bag fixing end 2321. When the first bag winding rod 231 and the second bag winding rod 232 are connected, the first bag fixing end 2311 abuts against the second bag fixing end 2321. Figure 6 As shown, both the first and second bag fixing ends are set to "L". The protrusion of the first bag fixing end and the concave part of the second bag fixing end match each other, which facilitates fixing the bag on the bag keel.

[0041] Preferably, the drive motor includes a first drive motor 210 and a second drive motor; the first bag winding rod 231 is connected to the output shaft of the first drive motor 210, the second bag winding rod 232 is connected to the output shaft of the second drive motor, and the first bag fixing end 2311 and the second bag fixing end 2321 are arranged facing each other; the bag fixing part also includes a first hydraulic cylinder 220 and a second hydraulic cylinder, which are respectively used to drive the first bag fixing end 2311 and the second bag fixing end 2321 to move towards each other.

[0042] In this embodiment, the first hydraulic cylinder 220 and the second hydraulic cylinder are fixed on the frame of the bag recycling mechanism 200. The piston rod of the first hydraulic cylinder 220 is connected to the first drive motor 210, and the piston rod of the second hydraulic cylinder is connected to the second drive motor. The first drive motor 210 and the second drive motor can move towards each other under the drive of the piston rods of the first hydraulic cylinder 220 and the second hydraulic cylinder. When the keel with the bag is transported to the predetermined position, the first hydraulic cylinder and the second hydraulic cylinder respectively drive the first drive motor 210 and the second drive motor to move towards each other. At the same time, they drive the first bag fixing end 2311 and the second bag fixing end 2321 to move towards each other until the first bag fixing end 2311 and the second bag fixing end 2322 abut against each other, fixing the bag on the keel to the bag winding rod, and then closing the first hydraulic cylinder 220 and the second hydraulic cylinder. Then, the first drive motor 210 and the second drive motor are started simultaneously, and the bag winding rod rotates until all the bags on the bag keel are wound onto the bag winding rod. Re-activate the first and second hydraulic cylinders, and the first and second bag fixing ends separate, allowing the bag wound on the bag winding rod to be removed.

[0043] like Figures 7-11As shown, the keel compression and recycling mechanism 300 includes a keel input section 310, a rotatable keel flipping section 320, and a keel compression section 330. The keel flipping section 320 includes at least two working positions: a first working position and a second working position. The keel input section 310 includes a keel fixing member 312 that can move along a predetermined hooking trajectory, used to hook the keel onto the keel flipping section 320 located in the first working position. The keel compression section 330 includes a compression member that can move along a predetermined compression trajectory, used to compress the bag keel located on the keel flipping section 320 in the second working position. The keel flipping section 320 achieves the switching between the first working position and the second position by flipping. In this embodiment, the keel compression section 330 includes a keel compression hydraulic cylinder 331 and a compression member connected to the piston rod of the keel compression hydraulic cylinder. The compression member moves in the vertical direction under the drive of the keel compression hydraulic cylinder 331, and the keel fixing member 312 moves in the front-back direction. The first working position of the keel flipping part 320 is used to support the part of the bag keel to be squeezed that is hooked by the keel input part, and the second working position of the keel flipping part 320 is used to bend the bag keel 500 so that the length direction of the part to be squeezed of the bent bag keel 500 is consistent with the predetermined squeezing trajectory.

[0044] In this embodiment, the keel input section 310 includes a keel input cylinder 311 and a keel fixing member 312 fixed on the piston rod of the keel input cylinder 311. The keel fixing member 312 includes a fixing frame 3123, a keel hook block 3121 hinged to the fixing frame 3123, and a hook limiting block 3122. The hook limiting block 3122 abuts against the rear of the keel fixing member 312.

[0045] When the keel input section 310 needs to hook the keel, the keel input cylinder 311 is activated, and the keel fixing member 312 moves backward. Since the keel hooking block 3121 is hinged to the fixing frame and there is no hooking limit block 3122 in front of the keel fixing member 312, the keel hooking block 3121 can move to the predetermined hooking position on the keel. When the keel fixing block is at the predetermined hooking position, the keel fixing member 312 moves forward. At this time, the keel hooking block 3121 is blocked by the hooking limit block 3122 and cannot swing backward, so the hooked bag keel 500 moves forward.

[0046] Because the entire fabric bag frame 500 is quite long, it cannot be compressed by the frame compression section 330 in one continuous operation. Therefore, the frame can be considered as being composed of several frame segments 510 connected along its length, each of which can be compressed by the frame compression section 330 in one operation. Furthermore, the entire frame is compressed into a ball by sequentially compressing each segment along its length.

[0047] Specifically, firstly, the keel input unit 310 hooks the keel section to be compressed onto the keel flipping unit 320, which is in the first working position. At this time, the length direction of the keel section to be compressed 510 is consistent with the front-to-back direction. Then, the keel flipping unit 320 flips to the second working position, the bag keel 500 is bent, and the keel section to be compressed 510 is pushed under the compression unit by the keel flipping unit 320, and the length direction of the keel section to be compressed 510 is consistent with the vertical direction. At this time, the keel compression hydraulic cylinder 331 is activated, and the compression member of the keel compression unit 330 moves in the vertical direction to compress the keel section to be compressed 510 along its length direction, thus completing the compression of the keel section to be compressed 510. Next, the keel flipping section 320 returns to the first working position, and the keel input section 310 hooks the next section of the bag keel to be compressed 510 onto the keel flipping section 320. The keel to be compressed section 510 is rotated to the predetermined compression position by the keel compression section 320 and compressed by the keel compression section 330. The above operation is repeated until each section 510 of the bag keel 500 is compressed into a ball by the keel compression section 330. At this time, the bag keel 500 is also finally compressed into a ball.

[0048] When the bag keel separating and recycling device is in operation, the bag keel 500 with the bag attached moves through the device. First, the bag attached to the bag keel 500 is cut on the bag keel separating mechanism 100, and then enters the bag recycling mechanism 200. The bag is wound by the bag winding rod 230 and is peeled off from the bag keel 500. Next, the bag keel 500 enters the keel compression recycling mechanism 300, is hooked by the keel fixing member 312 on the keel input part 310 and inserted into the keel turning part 320, and is compressed into a ball by the keel compression part 330.

[0049] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
