Description

Technical Field

[0001] This utility model relates to the field of ton bag feeding technology, specifically to a ton bag feeding machine. Background Technology

[0002] Ton bags are flexible transport packaging containers with advantages such as moisture-proof, dust-proof, sturdy and safe, and are widely used due to their sufficient structural strength. Ton bags are suitable for packaging bulk grains, feed, chemical raw materials, starch, minerals, and even hazardous materials such as calcium carbide, making loading, unloading, transportation, and storage very convenient. Ton bag unloading requires a ton bag feeder. During the unloading process, material inside the ton bag is prone to accumulation and blockage at the bottom of the hopper, affecting material discharge. Furthermore, material stored in ton bags for a long time is prone to caking or clumping. Because existing ton bag feeders lack a material-dispersing mechanism, caking or clumping material is directly discharged from the ton bag, resulting in a mixture of caking or clumping material in the discharged material, affecting subsequent processing or use. Utility Model Content

[0003] To address the problems of existing technologies, this utility model provides a ton bag feeding machine, including a ton bag, with a feeding hopper located below the ton bag. An anti-accumulation mechanism is provided on the outer side of the lower end of the feeding hopper. The anti-accumulation mechanism includes three drive rods and a first drive motor. A first gear is mounted on the power output shaft of the first drive motor, and the first gear meshes with a second gear. Each of the three drive rods is equipped with a second gear.

[0004] Each drive rod is equipped with a synchronous pulley, and the three synchronous pulleys are rotatably connected by a synchronous belt. Each drive rod is equipped with a turntable at the top, and the outer ring of the turntable is evenly distributed with a number of vibrating balls. The vibrating balls are rotatably connected to the turntable by springs.

[0005] The lower end of the feeding hopper is connected to the upper end of the discharge pipe through the feeding pipe. The lower end of the discharge pipe is provided with a discharge port. A second drive motor is detachably installed on the top wall at the center of the discharge pipe. The power output end of the second drive motor extends into the feeding pipe and is connected to a round rod. The outer wall of the round rod is rotatably connected to the inner bottom wall of the discharge pipe through a bearing. A lever is provided on the outer wall of the round rod, and a baffle is also provided at the bottom of the outer wall of the round rod.

[0006] A further embodiment is that the three drive rods are arranged in a triangle, and each of the three drive rods is located at the vertex of an equilateral triangle.

[0007] A further embodiment is that the outer ring of the bearing is fixedly connected to the inner wall of the discharge pipe through a bearing seat, and the inner ring of the bearing is interference-fitted to the outer wall of the round rod.

[0008] A further option is to irregularly provide several levers on the outer wall of the round rod from top to bottom.

[0009] A further embodiment is that the baffle is located at the bottom of the lever, and the upper surface of the baffle is set as an inclined surface.

[0010] A further embodiment includes a puncturing mechanism fixedly installed inside the hopper for puncturing the ton bag. The puncturing mechanism includes a knife holder, several puncturing knives mounted on the knife holder, and a cross-shaped support base. The knife holder includes a mounting frame and several positioning strips connected to the mounting frame. One end of each positioning strip is connected to the mounting frame, and the positioning strips are inclined outwards away from the mounting frame. The positioning strips are evenly spaced, and the bottom of each positioning strip is fixedly connected to the support base.

[0013] The beneficial effects of this utility model are:

[0014] This invention features an anti-accumulation mechanism at the bottom of the hopper. When a large amount of material from the ton bag flows to the bottom of the hopper, a first drive motor drives a first gear to rotate, which in turn drives a second gear to rotate, which in turn drives a turntable to rotate. The turntable then drives a vibrating ball and a spring to rotate, causing the vibrating ball to strike the bottom of the hopper, thus preventing material from accumulating and clogging at the bottom of the hopper and ensuring smooth material discharge.

[0015] This invention uses a second drive motor to rotate a lever, which in turn strikes the material. The material is then struck against the inner wall of the feed pipe, creating an impact effect. This double impact breaks up any clumps or agglomerates, thus preventing the material from clumping when it exits the ton bag. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figure 1-6 As shown, one embodiment of this utility model discloses a ton bag feeding machine, including a ton bag 1, a feeding hopper 2 arranged below the ton bag 1, a hanging strap 80 connected to the upper end of the ton bag 1, the ton bag 1 is hung on a hook 81 by the hanging strap 80, the hook 81 is fixedly arranged at the bottom of the mounting plate 82, the top of the mounting plate 82 is fixedly connected to the movable end of an electric push rod 83, and the electric push rod 83 is fixedly arranged on the frame 84.

[0025] The hopper 2 is fixedly equipped with a puncturing mechanism for puncturing the ton bag 1. The puncturing mechanism includes a knife holder 60, a plurality of puncturing knives 61 mounted on the knife holder 60, and a cross-shaped support base 62. The knife holder 60 includes a mounting frame 600 and a plurality of positioning strips 601 connected to the mounting frame 600. One end of the positioning strip 601 is connected to the mounting frame 600. The positioning strips 601 are inclined outward away from the mounting frame 600. The plurality of positioning strips 601 are evenly spaced. The bottom of each positioning strip 601 is fixedly connected to the support base 62. The puncturing knives 61 correspond one-to-one with the positioning strips 601 and are mounted on the positioning strips 601. The plurality of puncturing knives 61 are conically distributed. The tops of the plurality of puncturing knives 61 are close to each other, and the blades of the plurality of puncturing knives 61 are provided with serrations 63 arranged side by side.

[0026] In this embodiment, the above-described setup allows the ton bag to be hung on the hook via a strap. Then, the electric push rod is activated, and the movable end of the electric push rod moves downward, thereby driving the mounting plate and the hook on the mounting plate, along with the ton bag hanging on the hook, to move vertically downward. During the downward pressure, the bottom of the ton bag comes into contact with the piercing blade. The conical piercing blade can pierce the bottom of the ton bag, and the serrations on the piercing blade can better cut through the ton bag, allowing the material inside the ton bag to flow into the discharge hopper.

[0027] An anti-accumulation mechanism is provided on the lower outer side of the hopper 2. The anti-accumulation mechanism includes three drive rods 30 and a first drive motor 31. The first drive motor 31 is fixedly mounted on the support plate 9, and the support plate 9 is fixedly connected to the frame 84. A first gear 32 is mounted on the power output shaft of the first drive motor 31, and the first gear 32 meshes with a second gear 33. A second gear 33 is mounted on each of the three drive rods 30.

[0028] Each drive rod 30 is equipped with a synchronous pulley 34, and the three synchronous pulleys 34 are rotatably connected by a synchronous belt 35. Each drive rod 30 is equipped with a turntable 36 at its top, and several vibrating balls 37 are evenly distributed on the outer ring of the turntable 36. The vibrating balls 37 are rotatably connected to the turntable 36 by a spring 38. The three drive rods 30 are arranged in a triangle, and the three drive rods 30 are located at the vertex of an equilateral triangle.

[0029] This embodiment, through the above-described configuration, enables the activation of the first drive motor to rotate the first gear when a large amount of material flows into the hopper. The rotation of the first gear drives the rotation of the second gear, which in turn drives the turntable to rotate. The rotation of the turntable drives the vibrating ball and spring to rotate, and the vibrating ball strikes the bottom of the hopper, causing the bottom of the hopper to vibrate. This prevents a large amount of material from accumulating and blocking the bottom of the hopper, and allows the material to fall smoothly into the discharge pipe.

[0030] In this embodiment, the top of the hopper 2 is provided with a hollow dust removal ring 7. The dust removal ring 7 has several through holes (not shown in the figure) communicating with its inner cavity. The inner cavity of the dust removal ring 7 is connected to the inside of the hopper 2 through the through holes. The inner cavity of the dust removal ring 7 is connected to the air inlet of an external negative pressure fan (not shown in the figure) through a duct 70. The air outlet of the negative pressure fan is connected to the inside of a dust collection box (not shown in the figure).

[0031] This embodiment, through the above-described configuration, enables the negative pressure fan to be activated, creating negative pressure within the dust collector ring. When the bottom of the ton bag is cut open, the material inside the ton bag flows into the feed hopper, generating a large amount of dust which is then sucked into the dust collector and drawn into the dust collection box through the air duct for collection. This prevents dust generated during ton bag unloading from rising upwards, polluting the external environment, and affecting the health of workers.

[0032] The lower end of the feeding hopper 2 is connected to the upper end of the discharge pipe 5 through the feeding pipe 4. The lower end of the discharge pipe 5 is provided with a discharge port 50. A second drive motor 51 is detachably provided on the top wall at the center of the discharge pipe 5. The power output end of the second drive motor 51 extends into the feeding pipe 4 and is connected to a round rod 52. The outer wall of the round rod 52 is rotatably connected to the inner bottom wall of the discharge pipe 5 through a bearing 53. A lever 54 is provided on the outer wall of the round rod 52. A baffle 55 is also provided at the bottom of the outer wall of the round rod 52.

[0033] In this embodiment, the above-described configuration enables the second drive motor to be activated when material falls from the bottom of the hopper and enters the discharge pipe. The second drive motor drives the round rod to rotate the lever, which in turn strikes the material against the inner wall of the discharge pipe, creating an impact effect. This double impact breaks up any clumps or agglomerates. Several levers on the outer wall of the round rod further disperse the material. After being dispersed, the material slides through a baffle into the discharge pipe and is discharged through the outlet, thus ensuring that the material discharged from the ton bag does not clump or agglomerate.

[0034] In this embodiment, the outer ring of the bearing 53 is fixedly connected to the inner wall of the discharge pipe 5 through the bearing seat, and the inner ring of the bearing 53 is interference-fitted with the outer wall of the round rod 52.

[0035] In this embodiment, the bearings can be used to fix the round rod, making it easier for the round rod to rotate through the bearings.

[0036] In this embodiment, the outer wall of the round rod 52 is irregularly provided with several levers 54 from top to bottom.

[0037] This embodiment, through the above-described configuration, enables the material to be struck by rotating the lever. The material is then struck against the inner wall of the feed pipe, creating an impact effect. This dual-impact effect breaks up the clumped material.

[0038] In this embodiment, the baffle 55 is located at the bottom of the lever 54, and the upper end surface of the baffle 55 is set as an inclined surface.

[0039] In this embodiment, the above-described configuration allows the dispersed material to slide through the baffle into the discharge pipe and be discharged through the discharge port of the discharge pipe.

[0040] Finally, it should be noted that the above description only details specific embodiments of this utility model. However, this utility model is not limited to the specific embodiments described above. Equivalent modifications and substitutions made to this utility model by those skilled in the art are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model are covered within the scope of this utility model.
