Description

Technical Field

[0001] This utility model relates to the industry of resource utilization of fly ash from municipal solid waste incineration, and in particular to a quick-opening mechanism for ton bags using a cross-saw saw. Background Technology

[0002] On July 10, 2024, the applicant filed an invention patent application with the China National Intellectual Property Administration entitled "Integrated Ton Bag Clumping and Crushing Device for Fly Ash," with publication number CN118893073A. The device includes a bag-breaking mechanism, a large-piece fly ash crushing mechanism, a small-piece fly ash crushing mechanism, a pulverizer, and a conveyor. However, when receiving and crushing ton bags containing deliquescent, solidified, or other special fly ash, problems arise such as the bottom of the ton bag not being able to be cut open, the fly ash and the ton bag sticking together as a single piece, and the fly ash sticking together as a single piece that cannot be broken.

[0003] In addition, the commonly used ton bag opening mechanism on the market is an arch-shaped structure composed of four blades. This is a fixed type, resulting in slow opening speed and low work efficiency. For powder materials, manual cutting is usually used to improve efficiency, but the working environment is harsh. When the material inside the ton bag is large, hard, or sticky, the ton bag sits on the tips of the four arched blades and cannot be cut open, making manual operation impossible. Utility Model Content

[0004] The technical problem this utility model aims to solve is that existing technologies often encounter problems when breaking down ton bags containing deliquescent or solidified fly ash. These problems include the inability to cut open the bottom of the ton bag, the fly ash sticking to the ton bag as a single piece, and the fly ash sticking together and being unable to be broken. This utility model provides a cross-saw ton bag quick-opening mechanism that uses mechanical means to smoothly open the packaging of deliquescent or solidified fly ash in ton bags, separating the packaging from the fly ash. This allows for the breaking down of large pieces of fly ash into smaller particles, meeting the particle size requirements of subsequent processes, reducing manual labor, and improving production efficiency.

[0005] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0006] A quick-opening mechanism for ton bags using a cross-saw saw includes:

[0007] Long and short saw blade modules are mounted in a cross shape on the frame;

[0008] A long saw blade configured within the long saw blade fixing groove in the long saw blade module;

[0009] A short saw blade configured in the short saw blade fixing groove within the short saw blade module;

[0010] The long saw blade is driven to reciprocate together with the long saw blade module by a long saw blade drive mechanism mounted on the frame, and the short saw blade is driven to reciprocate together with the short saw blade module by a short saw blade drive mechanism mounted on the frame.

[0011] In a preferred embodiment of this utility model, both ends of the long saw blade module and the short saw blade module are mounted on a buffer spring. When the ton bag is pressed on the long saw blade module and the short saw blade module, the long saw blade module and the short saw blade module can be lowered, so that the saw teeth of the long saw blade and the short saw blade protrude from the top of the long saw blade module and the top of the short saw blade module, and fully contact the bottom of the ton bag.

[0012] In a preferred embodiment of this utility model, anti-deviation strips are provided on both the long saw blade module and the short saw blade module to prevent the long saw blade and the short saw blade from deflecting.

[0013] Due to the adoption of the above technical solution, this utility model has the following advantages:

[0014] 1. Employing a cross-saw blade ton bag quick-opening mechanism, the thin and sharp blade rapidly slices open the bottom of the ton bag through short-distance reciprocating motion. Furthermore, the short teeth and wide tooth pitch of the blade ensure rapid opening with low resistance, preventing bag snagging and effectively protecting both long and short saw blades, resulting in a long service life.

[0015] 2. Both ends of the long saw blade module and the short saw blade module are mounted on buffer springs. When the ton bag is pressed on the long saw blade module and the short saw blade module, the long saw blade module and the short saw blade module can be lowered, so that the saw teeth of the long saw blade and the short saw blade protrude from the top of the long saw blade module and the top of the short saw blade module, and make full contact with the bottom of the ton bag, while avoiding damage to the saw blade module and the saw blade.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] See Figures 1 to 5 The figure shows a cross-saw blade ton bag quick opening mechanism 400, which includes: a long saw blade module 410 and two short saw blade modules 420a and 420b installed in a cross shape on a frame 100, a long saw blade 430, two short saw blades 440a and 440b, a long saw blade fixing groove 450, and two short saw blade fixing grooves 460a and 460b.

[0023] The long saw blade 430 and the short saw blades 440a and 440b are respectively installed in the long saw blade fixing groove 450 and the two short saw blade fixing grooves 460a and 460b using fasteners such as fastening bolts and fastening nuts. The long saw blade 430 and the two short saw blades 440a and 440b are respectively configured in the long saw blade module 410 and the two short saw blade modules 420a and 420b with the long saw blade fixing groove 450 and the two short saw blade fixing grooves 460a and 460b respectively. At one end of the long saw blade fixing groove 450 and the two short saw blade fixing grooves 460a and 460b, the long saw blade drive mechanism 470 and the short saw blade drives 480a and 480b (e.g., linear motion mechanisms) mounted on the frame 100 drive the long saw blade 430 and the short saw blades 440a and 440b to reciprocate linearly with the long saw blade module 410 and the two short saw blade modules 420a and 420b, respectively, to quickly cut open the bottom of the ton bag. Anti-deviation strips (not shown in the figure) are provided in both the long saw blade slide 410 and the short saw blade slides 420a and 420b to prevent the long saw blade 430 and the short saw blades 440a and 440b from deflecting. Both ends of the long saw blade slide 410 and the short saw blade slides 420a and 420b are mounted on a buffer spring 490. When the ton bag is pressed on the long saw blade slide 410 and the short saw blade slides 420a and 420b, the long saw blade slide 410 and the short saw blade slides 420a and 420b can be lowered, so that the saw teeth 431 of the long saw blade 430 and the saw teeth 441a and 441b of the short saw blades 440a and 440b protrude from the top of the long saw blade slide 40 and the top of the short saw blade slides 420a and 420b, and make full contact with the bottom of the ton bag.

[0024] When breaking the bag, the entire ton bag of fly ash is placed on the anti-deviation strips of the long saw blade module 410 and the short saw blade modules 420a and 420b. The weight of the ton bag is borne by the anti-deviation strips of the long saw blade slide 410 and the short saw blade slides 420a and 420b, effectively protecting the long saw blade 430 and the short saw blades 440a and 440b. The cross-saw blade ton bag quick opening mechanism 400 is activated to break the cross-shaped opening at the bottom of the ton bag.
