Technical Field

[0001] The utility model belongs to the technical field of dust removal equipment maintenance, and in particular relates to a device for pulling and disassembling waste dust removal bags. Background Art

[0002] In the field of industrial dust treatment, the performance of dust removal equipment directly affects the dust collection and purification effect. As a key component of dust removal equipment, the convenience of installation and replacement of used dust bags and their compatibility with the equipment are important factors affecting the performance of the equipment. After a period of use, the used dust bags need to be replaced. As some of the used dust bags are damaged, dust dust is poured into the used dust bags, resulting in an increase in the weight of the used dust bags. Manual operation and disassembly are labor-intensive and work efficiency is low.

[0003] Therefore, a device for pulling and removing waste dust bags is developed which can improve work efficiency and reduce labor intensity. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0018] See also Figures 1 to 5A device for pulling and disassembling waste dust bags comprises a support frame 1, two vertically arranged lifting cylinders 2 installed on the support frame, a lifting plate 3 is installed on the upper end of the piston rod of the lifting cylinder, and a waste dust bag stop assembly 4 is installed on the center hole of the lifting plate; two symmetrically arranged driving roller assemblies 5 are also installed on the support frame at the lower part of the lifting cylinder, and the two driving rollers are used to clamp the waste dust bag 7 after rolling; when the waste dust bag is actually pulled at the beginning or the driving roller assembly slips when clamping the waste dust bag, the lifting cylinder is started to assist the pulling; in addition, when the piston rod of the lifting cylinder is in an extended state, the waste dust bag passes through the center hole of the lifting plate, which has the function of straightening and guiding, and is conducive to pulling.

[0019] Preferably, the waste dust bag anti-recognition assembly 4 includes a anti-recognition ring seat 4-1 fixedly mounted on the lifting plate, a pawl assembly 4-2 is installed on the anti-recognition ring seat along the circumferential direction, the pawl assembly includes a pawl seat 4-3, a pawl 4-4 installed on the pawl seat to prevent the waste dust bag from sliding down, the pawl 4-4 tends to a horizontal state due to its own weight without the action of external force, when the waste dust bag moves upward, the pawl rotates counterclockwise and has no restraining force on the waste dust bag; when the waste dust bag has a downward movement tendency, the pawl rotates clockwise from top to bottom, and on the basis of the downward movement force of the waste dust bag, the pawl will be inserted into the waste dust bag, forming a damping for the waste dust bag to prevent the waste dust bag from moving downward.

[0020] Preferably, the driving roller assembly 5 comprises a fixed frame 5-1, and swing frames 5-2 symmetrically hinged on the fixed frame on both sides, a driving shaft 5-3 is installed on the upper part of the swing frame, a driving roller 5-4 is installed on the driving shaft, and one end of the driving shaft is connected to a driving motor 5-5; driving roller opening and closing cylinders 5-6 are connected to the lower ends of the two swing frames on both sides, so that the driving rollers clamp the waste dust bags. The driving motor in the driving roller assembly drives the driving shaft and the driving roller to rotate, so that the driving rollers roll and pull the waste dust bags.

[0021] The driving roller is a concave wheel structure, and the outer surface of the concave wheel is made of a material that increases friction and is rough. It is installed on the driving shaft and driven to rotate by the driving motor 5-5. When the driving roller opening and closing cylinder 5-6 is recovered, the driving roller clamps the waste dust bag. Since the waste dust bag is removed by pulling out the waste dust bag together with its internal bag dragon, the waste dust bag will not be squeezed and flattened under the support of the internal bag dragon, and friction can be generated between the driving roller and the driving roller. Under the action of friction, the driving roller rotates to drive the waste dust bag and the bag dragon frame to move upward and away from the flower plate, thereby realizing the removal of the waste dust bag.

[0022] Preferably, the driving shaft at both ends of the driving roller is threaded with limit nuts 5-7, and the limit nuts at both ends of the driving roller are threaded with limit nuts, which can ensure the stability and accuracy of the driving roller when clamping the waste dust bag and prevent the driving roller from deviating.

[0023] Preferably, the support frame 1 includes two support platforms 1-1, and support plates 1-2 are fixedly connected to the upper surfaces of the two support platforms. A waste dust bag passing hole 1-3 is provided at the center of the support plate, and the waste dust bag passing hole is larger than the waste dust bag installation hole 6-1 on the dust removal equipment panel 6.

[0024] When implementing the waste dust bag pulling and disassembling device of the utility model, the device is placed on the dust removal equipment plate 6, so that the center of the support plate is provided with a waste dust bag through hole 1-3 corresponding to the waste dust bag installation hole 6-1, and the lifting cylinder cooperates with a quick pulling device (when disassembling, the utility model can use a waste dust bag pulling device previously developed by the utility model, and its patent publication number is CN217092662U)) to pass a waste dust bag pulling device through the center hole on the lifting plate 3, and hang the handle of the device on the lifting plate 3, The piston of the lifting cylinder rises, driving the lifting plate 3 to rise, and the lifting plate drives a waste dust bag extraction device on which the waste dust bag and the bag keel frame have been hung to move upward, thereby separating the waste dust bag from the flower plate; in the initial extraction process, the two driving rollers are in an open state and do not contact the waste dust bag; when the bag mouth of the waste dust bag is completely separated from the flower plate and rises to the upper part of the driving roller 5-4, the piston rod of the driving roller opening and closing cylinder 5-6 is recovered, driving the driving roller 5-4 to clamp the waste dust bag, and the waste dust bag extraction device is disassembled. Start the drive motor 5-5 to drive the drive roller 5-4 to continuously pull; when the drive motor 5-5 power cannot drive the drive roller 5-4 to pull the waste dust bag and slip occurs, the lifting cylinder works and moves upward, and the waste dust bag or its internal bag dragon is hung tightly under the action of the ratchet, and the waste dust bag is pulled again. The drive roller and the lifting cylinder cooperate to completely disassemble the waste dust bag. Since the lifting cylinder only moves upward, the efficiency of pulling with the lifting cylinder alone is relatively low, but the force is strong. Therefore, the auxiliary role of the lifting cylinder is started only when the drive motor cannot effectively pull; the main pulling relies on the continuous work of the drive roller to improve work efficiency.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
