Description

Technical Field

[0001] This utility model relates to the field of waste treatment, and in particular to a novel bag-breaking machine. Background Technology

[0002] In modern cities, a large amount of construction and renovation waste is generated daily. For environmental protection, saving land for landfill, and resource recycling, timely disposal is necessary. To facilitate processing and transportation, current regulations require construction waste to be bagged and transported by vehicle to a centralized waste collection area for crushing. Before processing, the garbage bags need to be broken, and then the waste enters the sorting line. Currently, this is done manually, with the bags opened and the waste placed on the sorting line. The drawbacks are: firstly, it is slow and inefficient, making it difficult to meet production demands; secondly, the working environment is dirty, harmful to workers' health, and the open bags pose a safety hazard due to the potential for dumping.

[0017] Figures 1 to 7 A novel bag-breaking machine according to one embodiment of the present invention is schematically shown. As shown in the figure, the novel bag-breaking machine includes: an outer frame 1, a support frame 2, a floating pressure frame 3, multiple lower bag-breaking rollers 4, and multiple upper bag-breaking rollers 5; The outer frame 1 has a horizontal upper support 11 at the upper end and a horizontal lower support 12 in the middle; further, the outer frame 1 includes four rectangular array of vertical columns 10, a horizontal upper support 11 fixedly connected to the upper end of the four vertical columns 10, and a horizontal lower support 12 fixedly connected to the middle of the four vertical columns 10.

[0018] The support frame 2 is inclined from the upper left to the lower right and is located above the lower support 12, with four vertical columns 10 fixedly connected at its four corners. The guide plate 20 of the support frame 2 is provided with multiple rows of transverse cutting holes 200 at equal intervals in the longitudinal direction, and the adjacent rows of cutting holes 200 are longitudinally staggered. The floating pressure frame 3 is inclined from the upper left to the lower right and is located below the upper support 11. Its four corners are connected to the lower support 11 through four guide components 31. The center of the floating pressure frame 3 is connected to the upper support 11 through a floating linear telescopic cylinder 32, or its two middle sides are connected to the upper support 11 through two floating linear telescopic cylinders 32. The floating plate 30 of the floating pressure frame 3 is arranged parallel above the guide plate 20 to form a bag-breaking channel for bagged garbage. The floating plate 30 is provided with upper knife holes 300 that are one-to-one with the lower knife holes 200. The floating plate 30 is provided with multiple rows of upper knife holes 300 at equal intervals in the longitudinal direction. The adjacent rows of upper knife holes 300 are laterally staggered, and each upper knife hole 300 and a lower knife hole 200 are vertically opposite each other. Multiple bag-breaking rollers 4 are arranged laterally at equal intervals. The longitudinal ends of the first roller body 40 are connected to the support frame 2 via lower bearing seats 41. Multiple bag-breaking knives 42 are installed longitudinally at equal intervals on the first roller body 40. The bag-breaking knives 42 enter and extend their cutting edges from the lower knife holes 200. Several bag-breaking rollers 4 are driven by a fixed motor 6 fixed on the lower support 12. Furthermore, each bag-breaking roller 4 has a passive double-row sprocket 8 installed at its end. Laterally adjacent passive double-row sprockets 8 are connected by a single-row transmission chain 9. A second driving sprocket 61 is installed on the drive shaft of the fixed motor 6, and the second driving sprocket 61 is connected to adjacent double-row sprockets 8 via a second drive chain 62.

Multiple upper bag-breaking knives 52 are installed at equal intervals longitudinally on the second roller bodies 50. Furthermore, the cutting directions of the lower bag-breaking knives 42 and the upper bag-breaking knives 52 are opposite to the movement of the packaging bag; the lower bag-breaking roller 4 rotates counterclockwise, and the upper bag-breaking rollers 5 rotate clockwise. The upper bag-breaking knives 52 enter and extend their cutting edges from the upper knife hole 300, with the height of the cutting edges extending from the knife hole preferably being 2-5 mm.

The advantages are: the structure is simple and the transmission is stable.

[0021] Under the influence of inertia and gravitational potential energy, bagged garbage enters the bag-breaking channel, moves along the guide plate 20 and is pressed by the upper floating plate 30, so that several lower bag-breaking knives 42 and several upper bag-breaking knives 52 effectively cut the lower and upper walls of the packaging bag, forming densely distributed cutting holes. The upper and lower opposite cutting holes are connected, causing the packaging bag to break into several pieces. When it moves out of the bag-breaking channel and falls, the garbage bag is pulled further apart and broken by the weight of the large pieces of heavy garbage, and the garbage and packaging bag are completely separated.

[0022] Furthermore, the outlet of the outer frame 1 is also connected to the closed discharge chute 01, and below the discharge chute 01 is the discharge conveyor 02 with a limit baffle.

[0023] The front end of the support frame 2 is also equipped with a feeding conveyor 03, and the end of the feeding conveyor 03 is flush with the right end of the guide plate 20.

[0024] This new type of bag-breaking machine cuts the lower half of the packaging bag using a fixed lower bag-breaking knife 52, while the upper bag-breaking roller 5 cuts the upper half. Some of the upper and lower cutting holes are interconnected, creating numerous semi-circular and overall cutting holes on the packaging bag. When the packaging waste comes out, it breaks into several pieces and escapes through these numerous semi-circular holes, thus completing the automatic bag-breaking and discharge process. Its advantages are: First, the device cuts the packaging bag vertically and vertically, with staggered cuts increasing the density of the cutting holes, resulting in good and fast bag-breaking effect; Second, automated bag breaking avoids injury to sorting workers and eliminates safety hazards; Third, the floating upper cutting structure allows the cutting blade to cut obliquely to the left or right or lift up to fit the packaging bag, achieving complete and efficient cutting with better results and effectively protecting the cutting blade from damage, extending its service life; Fourth, the outer frame 1 has a three-dimensional structure, facilitating stable bag breaking.

[0025] Furthermore, each lower cutting hole 200 is a transverse rectangular hole, with a small gap between the lower bag-breaking knife 42 and the lower cutting hole 200; each upper cutting hole 300 is a transverse rectangular hole, with a small gap between the upper bag-breaking knife 52 and the upper cutting hole 300. The lower cutting hole 200 is preferably a rectangular gradient hole, with its diameter gradually increasing from top to bottom; the upper cutting hole 300 is preferably a rectangular gradient hole, with its diameter gradually decreasing from top to bottom. The lower bag-breaking knife 42 and the upper bag-breaking knife 52 are preferably circular saw blades. Preferably, the lower wall of the guide plate 20 is fixedly provided with several sets of lower elastic blocks 21, with two lower elastic blocks 21 in each set symmetrically arranged on both sides of the longitudinal edge of the lower cutting hole 200 and fitting against the side walls of the lower bag-breaking knife 42; the upper wall of the floating plate 30 is fixedly provided with several sets of upper elastic blocks, with two upper elastic blocks in each set symmetrically arranged on both sides of the longitudinal edge of the upper cutting hole 300 and fitting against the side walls of the upper bag-breaking knife 52. The lower elastic blocks 21 and the upper elastic blocks are preferably rubber blocks or nylon blocks. Its effect is that this setting is beneficial for rapid and stable cutting of bags.

[0026] Furthermore, the lower support 12 and the carrier frame 2 are fixedly connected by multiple central connecting columns 14, and four side end plates are threaded to the four sides respectively. The front and rear ends of the diversion plate 20 and the floating plate 30 are flush with the sealing plate 13; the upper support 11 and the carrier frame 2 are threaded to four skirt rubber plates. The carrier frame 2 and the lower support 12 form a three-dimensional frame with high strength and strong load-bearing capacity, which facilitates good and stable cutting and bag breaking.

[0027] Furthermore, the guide assembly 31 includes a central guide rod 311 and linear bearings 312. Four linear bearings 312 are fixedly connected to the four corners of the upper bracket 11. The lower end of the central guide rod 311 is fixedly connected to the four lower corners of the upper bracket 11, and the upper end is linearly slidably connected to the linear bearings 312, with its large-diameter limiting end plate 313 located above the linear bearings 312. The floating linear telescopic cylinder 32 is a single-axis cylinder with a floating joint 33 installed at the end of the telescopic rod. The seat end of the single-axis cylinder is hinged to the center of the lower wall of the upper bracket 11 or both sides of the lower wall. The lower end of the floating joint 33 is fixedly connected to the middle of the upper wall of the floating pressure frame 3. The floating distance of the floating linear telescopic cylinder 32 does not exceed 4cm. Its beneficial effect is that this setting can form a good floating bag breaking effect.

[0028] Furthermore, the upper support 11, lower support 12, bearing frame 2, and floating pressure frame 3 all include a skeleton formed by longitudinal beams and transverse beams connected perpendicularly to each other, and multiple longitudinal intermediate supports are provided in the middle of the skeleton. The beneficial effect is that this design has high structural strength and facilitates stable bag breaking.
