Description

Technical Field

[0001] This utility model relates to the field of bag breakers, and more particularly to a bag breaker for ton bags. Background Technology

[0002] A ton bag breaker is a manual or semi-automatic tool specifically designed for safely and efficiently cutting open the bottom or body of large ton bags. It is mainly used in industries such as chemical, food, and mining to quickly unload powdery or granular materials from the bags, while avoiding dust and material waste.

[0003] Utility model patent CN219635692U discloses a ton bag breaker. Its key technical features include: a barrel body, a barrel lid, a discharge hopper at the bottom of the barrel body, and supporting legs. A detachable multi-faceted blade cone is mounted inside the barrel body via a support frame. The barrel body has a double-layer shell composed of an inner shell and an outer shell. The multi-faceted blade cone includes several single-edged blades connected at the top. The apex of the multi-faceted blade cone is located on the central axis of the barrel body, and the height of the apex is lower than the top of the barrel body. The barrel lid is mounted on the top of the barrel body via a lifting mechanism, and a hook is provided on the side of the barrel lid facing the barrel body. This utility model, by setting up a barrel lid, barrel body, multi-faceted blade cone, support frame, and hook, facilitates blade replacement while preventing dust overflow.

[0004] The existing ton bag breaker technology has the following disadvantages: during the bag breaking operation, it lacks an automatically adjustable lateral support structure. During the bag breaking process, the ton bag is prone to swaying or tilting due to the unstable center of gravity after the bottom is punctured, resulting in inaccurate bag breaking position and low efficiency. At the same time, the existing equipment lacks an effective side shielding device, and the dust and debris generated during bag breaking are easily splashed and scattered in all directions, which not only pollutes the surrounding environment, but also harms the health of the operators. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a ton bag breaker.

[0006] To solve the above-mentioned technical problems, this utility model provides a ton bag breaker, comprising: a support frame, a hopper fixedly connected to the inner wall of the support frame, the upper end of the hopper being the feeding end and the lower end of the hopper being the discharging end; a welding frame fixedly connected to the inner wall of the hopper, a bag-breaking knife mounted on the upper surface of the welding frame; an adjustment assembly provided on the outer wall of the hopper, the adjustment assembly comprising a connecting frame and four fixed seats, the fixed seats being fixedly connected to the upper end of the hopper; a baffle rotatably connected to the inner wall of the fixed seat, a connecting rod rotatably connected to one side of the baffle; the ends of the four connecting rods away from the baffles being rotatably connected to the outer wall of the connecting frame; support plates fixedly connected to both sides of the outer wall of the hopper; a hydraulic cylinder fixedly connected to one side of the support plate, the output end of the hydraulic cylinder being fixedly connected to the lower surface of the connecting frame.

[0007] The above-mentioned components achieve the following effects: by setting the adjustment components, two effects are achieved: first, when using the bag breaker to break ton bags, the baffle can be automatically adjusted to support the side wall of the ton bag, improving the stability during the bag breaking process; second, the baffle can be automatically adjusted to shield the side of the ton bag, preventing dust from splashing and spreading during the bag breaking process and affecting the surrounding environment.

[0008] Preferably, the same elastic sealing cloth is fixedly connected to the side of two adjacent baffles that are close to each other, so as to seal the gap between the baffles.

[0009] The effect achieved by the above components is to seal the gaps between adjacent baffles with elastic sealing cloth, preventing dust or fine particles from leaking from the gaps on the side of the baffles during the process of bag breaking and material falling, thereby further enhancing the dustproof sealing effect and improving the cleanliness of the operating environment.

[0010] Preferably, the baffle has a plurality of flow guide holes on the side away from the connecting rod, and the flow guide holes are evenly distributed on one side of the baffle.

[0011] The effect achieved by the above components is that when the baffle lifts or blocks the ton bag, the guide hole can guide the dust, liquid or debris that may remain on the surface of the bag to slide down the trough into the hopper, avoiding its accumulation or splashing on the baffle surface, making it easier to clean and improving the material recovery rate.

[0012] Preferably, positioning plates are fixedly connected to both sides of the outer wall of the hopper, and positioning rods are slidably passed through the surface of the positioning plates, with the upper end of the positioning rods fixedly connected to the lower surface of the connecting frame.

[0013] The effect achieved by the above components is that the positioning rods cooperate with the positioning plates to vertically guide the movement direction of the connecting frame when the hydraulic cylinder drives the connecting frame to rise and fall, preventing the connecting frame from tilting or shaking, thereby ensuring that the four connecting rods drive the baffle to rotate synchronously and stably.

[0014] Preferably, the lower end of the hopper is provided with a discharge assembly, which includes a conical tube. The upper end of the conical tube is fitted and connected to the lower end of the hopper. Both sides of the outer wall of the conical tube are fixedly connected to a bearing plate. The cross-section of the bearing plate is "L"-shaped. A screw hole is opened on one side of the vertical part of the bearing plate. Two fixed cylinders are fixedly connected to the outer wall of the hopper. The vertical part of the bearing plate is slidably inserted into the inner wall of the fixed cylinder. A bolt is threaded through one side of the outer wall of the fixed cylinder. The bolt is adapted to the size of the screw hole. The lower end of the conical tube is fixedly connected to a corrugated pipe. The end of the corrugated pipe away from the conical tube is fixedly connected to a connecting pipe.

[0015] The effects achieved by the above components are as follows: by setting the discharge assembly, the bag breaker can adapt to the needs of different discharge heights or docking equipment; the corrugated pipe provides a flexible connection, which facilitates the sealing and docking of the connecting pipe with the downstream material port and reduces dust overflow.

[0016] Preferably, a pull rope is fixedly connected to the outer wall of the connecting pipe.

[0017] The effect achieved by the above components is that the pull rope allows the operator to pull the connecting pipe from a position away from the discharge port to adjust its docking position or angle.

[0018] Preferably, the upper end of the vertical portion of the support plate is configured as a tapered structure.

[0019] The effect achieved by the above components is that the tapered structure at the upper end of the vertical part of the bearing plate can automatically center when the fixed cylinder is inserted, reducing installation resistance and avoiding jamming.

[0020] Compared with related technologies, the ton bag breaker provided by this utility model has the following beneficial effects: This utility model provides a ton bag breaker, which achieves two effects by setting an adjustment component: first, when using the breaker to break ton bags, the baffle can be automatically adjusted to support the side wall of the ton bag, improving the stability during the breaking process; second, the baffle can be automatically adjusted to shield the side of the ton bag, preventing dust from splashing and spreading during the breaking process and affecting the surrounding environment.

[0021] By setting up the discharge components, the bag breaker can adapt to different discharge heights or docking equipment requirements. The corrugated pipe provides a flexible connection, which facilitates the sealing and docking of the connecting pipe with the downstream material port and reduces dust overflow.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figure 1 and Figure 2 The present invention provides a bag breaker for ton bags, comprising: a support frame 1, a hopper 2 fixedly connected to the inner wall of the support frame 1, the upper end of the hopper 2 being the feeding end and the lower end of the hopper 2 being the discharging end, a welding frame 5 fixedly connected to the inner wall of the hopper 2, a bag-breaking knife 6 installed on the upper surface of the welding frame 5, an adjustment component 3 provided on the outer wall of the hopper 2, and a discharging component 4 provided at the lower end of the hopper 2.

[0027] In the embodiments of this utility model, please refer to Figures 3 to 5The adjusting component 3 includes a connecting frame 304 and four fixed seats 301. The fixed seats 301 are fixedly connected to the upper end of the hopper 2. A baffle 302 is rotatably connected to the inner wall of the fixed seat 301. A connecting rod 303 is rotatably connected to one side of the baffle 302. The ends of the four connecting rods 303 away from the baffle 302 are rotatably connected to the outer wall of the connecting frame 304. Support plates 305 are fixedly connected to both sides of the outer wall of the hopper 2. A hydraulic cylinder 306 is fixedly connected to one side of the support plate 305. The output end of the hydraulic cylinder 306 is fixedly connected to the lower surface of the connecting frame 304. The adjusting component 3 achieves two effects: firstly, when using a bag breaker to break ton bags, the baffle 302 can be automatically adjusted to support the side walls of the ton bags, improving stability during the breaking process; secondly, the baffle 302 can be automatically adjusted to shield the sides of the ton bags, preventing dust from splashing and affecting the surrounding environment during the breaking process. Two adjacent baffles 302 are fixedly connected to the same elastic sealing cloth 310 on their closest sides to each other, which is used to seal the gap between the baffles 302. By sealing the gap between adjacent baffles 302 with the elastic sealing cloth 310, dust or fine particles are prevented from leaking from the side gaps of the baffles 302 during bag breaking and material falling, further enhancing the dustproof sealing effect and improving the cleanliness of the operating environment. Several guide holes 309 are opened on the side of the baffle 302 away from the connecting rod 303, and the guide holes 309 are evenly distributed on one side of the baffle 302. When the baffle 302 lifts or blocks the ton bag, the guide holes 309 can guide any dust, liquid or debris that may remain on the surface of the bag to slide directionally into the hopper 2 along the trough, avoiding accumulation or splashing on the surface of the baffle 302, facilitating cleaning and improving the material recovery rate. Positioning plates 307 are fixedly connected to both sides of the outer wall of hopper 2. Positioning rods 308 are slidably inserted through the surface of the positioning plates 307. The upper end of the positioning rods 308 is fixedly connected to the lower surface of the connecting frame 304. The positioning rods 308 cooperate with the positioning plates 307 to vertically guide the movement direction of the connecting frame 304 when the hydraulic cylinder 306 drives the connecting frame 304 to rise and fall, preventing the connecting frame 304 from tilting or shaking, thereby ensuring that the four connecting rods 303 synchronously and stably drive the baffle 302 to rotate.

[0028] In the embodiments of this utility model, please refer to Figure 6 and Figure 7The discharge assembly 4 includes a tapered tube 41, the upper end of which is fitted and connected to the lower end of the hopper 2. Support plates 46 are fixedly connected to both sides of the outer wall of the tapered tube 41. The support plates 46 have an "L"-shaped cross-section. A screw hole 47 is provided on one side of the vertical portion of the support plate 46. Two fixed cylinders 44 are fixedly connected to the outer wall of the hopper 2. The vertical portion of the support plate 46 is slidably inserted into the inner wall of the fixed cylinders 44. A bolt 45 is threaded through one side of the outer wall of the fixed cylinder 44, and the bolt 45 is matched to the size of the screw hole 47. A corrugated pipe 42 is fixedly connected to the lower end of the tapered tube 41, and a connecting pipe 43 is fixedly connected to the end of the corrugated pipe 42 away from the tapered tube 41. By setting the discharge assembly 4, the bag breaker can adapt to different discharge heights or docking equipment requirements. The corrugated pipe 42 provides a flexible connection, facilitating a sealed connection between the connecting pipe 43 and the downstream material inlet, reducing dust spillage. A pull rope 48 is fixedly connected to the outer wall of the connecting pipe 43. The pull rope 48 allows operators to pull the connecting pipe 43 from a position away from the discharge port to adjust its docking position or angle. The upper end of the vertical part of the support plate 46 is designed with a tapered structure. The tapered structure at the upper end of the vertical part of the support plate 46 can automatically center when the fixed cylinder 44 is inserted, reducing installation resistance and preventing jamming. The working principle of the ton bag breaker provided by this utility model is as follows: When it is necessary to break open a ton bag and control dust leakage, the operator first hoists the ton bag above hopper 2, aligning the bottom of the ton bag with the feed end at the top of hopper 2. Then, the hydraulic cylinder 306 is activated. The output end of the hydraulic cylinder 306 pushes the connecting frame 304 upward. The connecting frame 304 drives the four connecting rods 303 to move synchronously. The connecting rods 303 push the baffles 302 to rotate upward around the fixed seat 301. During this process, the positioning rod 308 slides vertically within the positioning plate 307, guiding the connecting frame 304 and preventing it from tilting. This ensures that the four baffles 302 smoothly move towards the center and support the sidewalls of the ton bag, thus breaking the bag. Secondly, the baffle 302 continues to rotate to a vertical position, forming a shield on the side of the ton bag. The elastic sealing cloth 310 between adjacent baffles 302 unfolds with the baffle 302 and automatically seals the gap. At the same time, the guide hole 309 on the inner side of the baffle 302 guides any residual dust or debris to slide into the hopper 2, avoiding accumulation or splashing. Finally, the ton bag falls stably under the constraint of the baffle 302, and its bottom is pierced by the bag-breaking knife 6 on the welding frame 5. The material falls into the lower discharge end through the hopper 2. The whole process achieves the dual effect of improving stability and preventing dust splashing and scattering through the lifting and shielding effect of the baffle 302.

[0029] When it is necessary to guide the material after bag breaking to different heights or connect it to the downstream inlet of different equipment, firstly, the operator selects the appropriate tapered tube 41 and corrugated tube 42 assembly according to the actual unloading height, inserts the vertical part of the bearing plate 46 into the fixed cylinder 44 on the outer wall of the hopper 2, and the tapered structure at the upper end of the bearing plate 46 automatically centers during the insertion process, reducing installation resistance. Then, the bolt 45 on one side of the fixed cylinder 44 is rotated to screw it into the screw hole 47 opened in the vertical part of the bearing plate 46, thereby connecting the upper end of the tapered tube 41 with the lower end of the hopper 2. The material is tightly fitted and fixed while maintaining continuity. Next, the operator holds the pull rope 48 and pulls the connecting pipe 43 to cause the corrugated pipe 42 to extend, retract, and bend, adjusting the connecting pipe 43 to the required position or angle to facilitate sealing and connection with the downstream feed inlet. Finally, the material is smoothly discharged from the hopper 2 through the conical pipe 41, corrugated pipe 42, and connecting pipe 43 to the target equipment. During this process, the flexible connection of the corrugated pipe 42 can effectively reduce dust spillage, and the pull rope 48 allows the operator to complete the adjustment without approaching the discharge port, improving the safety and convenience of operation.
