Description

Technical Field

[0001] This utility model relates to the technical field of feeding anti-pinch equipment, and in particular to a ton bag feeding docking anti-pinch device. Background Technology

[0002] Ton bag feeding is an efficient material handling method, typically used for the handling and addition of large quantities of bulk materials. During operation, workers use forklifts, cranes, or manually to move ton bags (large, sturdy, flexible packaging bags, generally with a capacity of around 1 ton) filled with material to the feeding port of designated equipment (such as reactors, silos, mixers, etc.). The bag seal is then opened, and the bag is tilted or auxiliary tools (such as vibration or compression) are used to ensure the material flows smoothly and continuously into the equipment. This method is suitable for materials with good flowability, such as granules and powders, and features relatively simple operation, large feeding capacity, and high efficiency. However, attention must be paid to dust control and material impact during the feeding process.

[0003] In industrial production, ton bags are commonly used for storing and transporting bulk materials. When feeding materials, it is usually necessary to manually operate an electric hoist to lift the ton bag and open the bag opening at the feeding port. However, in the current technology, due to the lack of anti-pinch mechanism, when the lifting lug of the ton bag breaks accidentally, the material may fall suddenly, which can easily injure the operator's arm, causing a work-related accident and seriously affecting the safety of the working environment and the level of protection for workers. Utility Model Content

[0004] One objective of this invention is to provide a ton bag feeding docking anti-pinch device. This invention addresses the problem mentioned in the background that, in industrial production, ton bags are commonly used for storing and transporting bulk materials. During feeding, it is usually necessary to manually operate an electric hoist to lift the ton bag and open the bag opening at the feeding port. However, in the prior art, due to the lack of an anti-pinch mechanism, when the ton bag lifting lug breaks accidentally, the material may suddenly fall, easily injuring the operator's arm and causing a work-related accident. This seriously affects the safety of the working environment and the level of worker protection.

[0005] A ton bag feeding docking anti-pinch device according to an embodiment of the present utility model includes:

[0006] Feeding assembly, including the outer casing and the internally installed material tank;

[0007] An anti-pinch assembly is installed on the top of the outer shell of the feeding assembly to support the ton bag. The anti-pinch assembly includes a second L-shaped fixing seat symmetrically fixed on the upper outer side of the outer shell. A detachable threaded sleeve is fixedly provided at the bottom of the second L-shaped fixing seat. A threaded post is threaded inside the threaded sleeve. A detachable support frame is fixedly provided at the top of the threaded post.

[0008] The material shaking component is installed at the bottom of the second L-shaped fixed seat in the anti-pinch component. The material shaking component includes a second electric push cylinder fixed to one side of the bottom of the second L-shaped fixed seat and a first rotating seat fixed to the top of the support frame. A pressure plate is rotatably arranged on the outside of the first rotating seat, and a second rotating seat is fixedly arranged at the bottom of the pressure plate.

[0009] The guide assembly, installed between the outer shell and the material tank in the feeding assembly, is used to clamp the discharge port of the ton bag.

[0010] Preferably, a hopper is installed at the bottom of the material tank, a cover plate is rotatably provided on one side of the outer shell via a hinge, a handle is fixedly provided on one side of the cover plate, the cover plate is opened and closed by a pushing component connected to the outer shell, and the cover plate is locked and released by a locking component connected to the outer shell.

[0011] Preferably, the outer side of the outer shell is circular and fixedly equipped with mounting bases.

[0012] Preferably, the pushing component includes a first L-shaped fixing seat symmetrically fixed on both sides of the cover plate, and a positioning post fixed below the corresponding first L-shaped fixing seat on the outer shell, and a first electric push cylinder is rotatably arranged between the first L-shaped fixing seat and the positioning post.

[0013] Preferably, the locking assembly includes symmetrically fixed blocks on both sides of the cover plate and a latch fixed on the corresponding side of the outer block. The blocks and latches correspond to each other and are engaged.

[0014] Preferably, the top of the support frame has a through groove.

[0015] Preferably, the second electric push cylinder and the second rotating seat are rotatably connected.

[0016] Preferably, the guiding assembly includes a third electric pusher cylinder that is circular and fixed inside the housing. The output end of the third electric pusher cylinder is fixedly provided with a pressure ring, which is located directly above the material tank.

[0017] The beneficial effects of this utility model are:

[0018] This invention effectively avoids the risk of workplace accidents caused by the lack of anti-pinch mechanisms by incorporating an anti-pinch component. During use, the support frame can be finely adjusted in height by rotating the threaded column within the threaded sleeve to accommodate different ton bags. Then, the lifting ring or strap of the ton bag is placed on the support frame. When the lifting lug of the ton bag breaks accidentally or fails to bear the load, the weight of the ton bag and materials originally borne by the lifting lug is instantly transferred to the support frame. The support frame transfers the load to the robust outer shell structure through the threaded column, threaded sleeve, and second L-shaped fixing seat. This rigid support frame immediately catches the falling ton bag and materials the moment the lifting lug fails, preventing them from falling rapidly and hitting the operator's arm below. This completely eliminates the risk of workplace accidents and significantly improves the safety of the working environment.

[0019] This invention effectively avoids the problems of poor material flowability and caking leading to difficult feeding and low efficiency by setting a material shaking component. When the ton bag is supported by the anti-pinch component, the second electric push cylinder is activated, pushing the pressure plate to reciprocate. The pressure plate rotates flexibly through the first and second rotating seats. Therefore, the linear motion of the electric push cylinder is converted into the circumferential up-and-down swing motion of the pressure plate through the second and first rotating seats. This patting structure can effectively loosen the material that may be caking or accumulating in the bag, making it easier for it to enter the material tank through the guide component. This not only improves the feeding efficiency, but also indirectly reduces the intervention and potential risks of operators in the feeding process, and improves the working environment.

[0020] This invention effectively avoids the problem of material spillage and waste caused by the inaccurate alignment or fixation of the ton bag's discharge port through the designed guiding component. After the ton bag is placed and roughly aligned, the operator activates the third electric push cylinder, which moves the pressure ring at its output end to the ton bag's discharge port. The operator then adjusts the pressure and position of the pressure ring as needed to tightly clamp and guide the discharge port directly above the material tank. This ensures that the material flows into the material tank accurately and in a concentrated manner, avoiding material spillage or deviation. Therefore, precise feeding is achieved, reducing material loss and environmental pollution, while ensuring the cleanliness and safety of the operation process. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] refer to Figure 1-4 A ton bag feeding docking anti-pinch device, comprising:

[0029] The feeding component 1 includes a housing 101 and a material tank 103 installed inside. A hopper 102 is installed at the bottom of the material tank 103. A cover plate 105 is rotatably provided on one side of the housing 101 via a hinge 106. A handle 107 is fixedly provided on one side of the cover plate 105. The cover plate 105 is opened and closed by connecting to the housing 101 through a pushing component. The cover plate 105 is locked and released by connecting to the housing 101 through a locking component.

[0030] The anti-pinch component 2 is installed on the top of the outer shell 101 of the feeding component 1 to support the ton bag. The anti-pinch component 2 includes a second L-shaped fixing seat 201 symmetrically fixed to the upper outer side of the outer shell 101. A detachable threaded sleeve 202 is fixedly installed at the bottom of the second L-shaped fixing seat 201. A threaded post 203 is threaded inside the threaded sleeve 202. A detachable support frame 204 is fixedly installed at the top of the threaded post 203. In use, the support frame can be finely adjusted in height by rotating the threaded post within the threaded sleeve to accommodate different ton bags. The bag is then placed on the support frame with its lifting ring or strap. When the lifting lug of the bag breaks accidentally or fails to bear the load, the weight of the bag and materials originally borne by the lifting lug will be instantly transferred to the support frame. The support frame transfers the load to the robust outer shell structure through the threaded column, threaded sleeve and second L-shaped fixing seat. This rigid bottom formed by the support frame immediately catches the falling bag and materials the moment the lifting lug fails, preventing them from falling rapidly and hitting the arms of the operator below, thus completely eliminating the risk of workplace accidents.

[0031] The material shaking component 3 is installed at the bottom of the second L-shaped fixed seat 201 in the anti-pinch component 2. The material shaking component 3 includes a second electric push cylinder 301 fixed to one side of the bottom of the second L-shaped fixed seat 201 and a first rotating seat 302 fixed to the top of the support frame 204. A pressure plate 303 is rotatably arranged on the outside of the first rotating seat 302, and a second rotating seat 304 is fixedly arranged at the bottom of the pressure plate 303. When the ton bag is supported by the anti-pinch component, the second electric push cylinder is activated, pushing the pressure plate to reciprocate. The pressure plate can rotate flexibly through the first rotating seat and the second rotating seat. Therefore, the linear motion of the electric push cylinder is converted into the circumferential up-and-down swing motion of the pressure plate through the second rotating seat and the first rotating seat. This patting structure can effectively loosen the material that may be hardened or accumulated in the bag, making it easier for it to enter the material tank through the guide component. This not only improves the feeding efficiency, but also indirectly reduces the intervention and potential risks of the operator during the feeding process.

[0032] The guide assembly 4 is installed between the outer shell 101 and the material tank 103 in the feeding assembly 1. It is used to clamp the discharge port of the ton bag. The guide assembly 4 includes a third electric push cylinder 401 that is circularly fixed inside the outer shell 101. A pressure ring 402 is fixedly provided at the output end of the third electric push cylinder 401. The pressure ring 402 is located directly above the material tank 103. When the ton bag is placed and roughly aligned, the operator activates the third electric push cylinder to move the pressure ring at its output end to the discharge port of the ton bag. The operator adjusts the pressure and position of the pressure ring as needed to tightly clamp and guide the discharge port to the top of the material tank. This ensures that the material can flow into the material tank accurately and centrally, avoiding the problem of material spillage or deviation. Therefore, accurate feeding is achieved, reducing material loss and environmental pollution.

[0033] Example 1: The outer side of the outer shell 101 is uniformly equipped with circular mounting bases 104 to facilitate the installation and fixation of the entire device. The pushing component includes first L-shaped fixing bases 108 symmetrically fixed on both sides of the cover plate 105, and positioning posts 110 fixed below the corresponding first L-shaped fixing bases 108 on the outer shell 101. A first electric push cylinder 109 is rotatably arranged between the first L-shaped fixing bases 108 and the positioning posts 110. When it is necessary to open or close the cover plate 105, the extension and retraction of the first electric push cylinder 109 will drive the cover plate 105 to rotate, realizing convenient operation. The locking component includes locking blocks 111 symmetrically fixed on both sides of the cover plate 105, and a latch 112 fixed on the corresponding side of the locking block 111 on the outer side. The locking blocks 111 and the latch 112 are corresponding to each other and are engaged. When the cover plate 105 is rotated to the closed position, the locking blocks 111 can accurately embed into the latch 112 to achieve a firm lock, prevent accidental opening, and ensure operational safety.

[0034] Example 2: The top of the support frame 204 is provided with a through groove 205, which allows the lifting straps or part of the bag structure of the ton bag to pass through, making the ton bag more stable and natural when placed on the support frame 204, and preventing unnecessary restraint or displacement caused by being completely blocked by the support frame. The second electric push cylinder 301 and the second rotating seat 304 are rotatably connected. When the second electric push cylinder 301 is working, the pressure plate 303 driven by it can not only perform linear push and pull motion, but also rotate at a certain angle at the second rotating seat 304.

[0035] Working principle: First, the height of the support frame 204 is finely adjusted by rotating the threaded column 203 to ensure the stability of the ton bag and that the bag opening is aligned with the material tank 103 of the feeding component. The operator places the lifting ring or strap of the ton bag on the support frame 204 of the anti-pinch component. At this time, the cover plate 105 is closed and locked, and the locking block 111 in the locking component engages with the latch 112, ensuring a safe and sealed feeding environment. After confirming the position of the ton bag, the outlet of the ton bag is aligned with the feeding port of the material tank 103. The guide component 4 is activated, and the third electric push cylinder 401 operates. The pressure ring 402 at its output end moves to the outlet of the ton bag and clamps it precisely, guiding the outlet to be aligned directly above the material tank 103 to ensure accurate material flow. During the feeding process, if the ton bag lifting lug breaks accidentally, the support frame 204 of the anti-pinch component 2 immediately bears the entire ton bag and The weight of the material is safely transferred to the outer shell 101 through the threaded column 203, threaded sleeve 202, and second L-shaped fixing seat 201, effectively preventing the ton bag and material from falling and injuring the operator. To promote the smooth flow of material, the shaking component 3 is activated, and the second electric push cylinder 301 pushes the pressure plate 303 to make linear reciprocating motion. The pressure plate 303 can rotate flexibly through the first rotating seat 302 and the second rotating seat 304, converting the linear motion of the electric push cylinder into circumferential up and down swinging, patting the bottom of the ton bag, effectively loosening the hardened material and improving the feeding efficiency. After feeding is completed, the cover plate 105 is closed, and the first electric push cylinder 109 runs in reverse to drive the cover plate 105 to rotate to the closed position. The locking block 111 is inserted into the locking buckle 112 again to lock it. Then, the pressure ring 402 is released, the ton bag is removed, and a safe and efficient ton bag feeding operation is completed.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
