Description

Technical Field

[0001] The utility model relates to the field of powder transportation, and more particularly to an auxiliary device for powder bagging. Background Art

[0002] In the recycling process of waste circuit boards, generally, mechanical crushing is used to separate metal components and non-metal components to form a powdery mixture, and then according to the property differences of the two components, sorting is carried out to screen out resin powder and metal powder. Whether it is resin powder or metal powder, it needs to be bagged for convenient transfer or transportation. Most of the packaging bags in the prior art are cloth bags with a volume of one cubic meter. When bagging the powder, workers are required to hold open the bag mouth of the cloth bag, and then the powder is loaded into the cloth bag through tools such as shovels or forklifts. This not only results in low efficiency of powder bagging, but also wastes manpower because workers are needed to hold open the bag mouth. Summary of the Utility Model

[0003] In view of this, the utility model provides an auxiliary device for powder bagging that is efficient and can reduce the use of manpower.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] An auxiliary device for powder bagging includes a movable frame, on which a feeding hopper, a foldable mesh cover, and a plurality of positioning components are provided; the feeding hopper has a top opening and a bottom opening, the mesh cover is located above the feeding hopper, and when fully unfolded, the mesh cover can block a part of the space above the top opening; the plurality of positioning components are arranged around the outer periphery of the feeding hopper, and each positioning component includes a limiting post provided on the frame, a flexible lasso sleeved on the limiting post, and a hook provided on the flexible lasso.

[0006] When the above device is in use, a cloth bag is placed under the feeding hopper, and the bag ears of the cloth bag are hooked by the hooks in the positioning components. Under the action of the plurality of hooks, the bag mouth of the cloth bag is opened, so that the bag mouth is located at the bottom opening of the feeding hopper. In this way, the powder can be loaded into the feeding hopper through a forklift or other tools and the powder can fall into the cloth bag smoothly, thus completing the powder bagging. Therefore, there is no need to manually open the bag mouth of the cloth bag, effectively reducing the use of manpower and improving the accuracy and efficiency of powder bagging.

[0007] Among them, the design of the movable frame facilitates adjusting the position of the equipment according to production requirements, increasing the flexibility of production. The design of the top opening and the bottom opening of the feeding hopper enables the powder to smoothly enter the bag, while the folding design of the mesh cover can protect the operator from direct contact with dust and can also cover part of the top opening when necessary to reduce the dust flying.

[0008] In addition, the setting of multiple positioning components ensures the stability of the bag during the bagging process and reduces the powder leakage caused by the offset of the bag position. And the positioning components include limit posts, flexible lassos and hooks, which not only ensure the firmness of positioning but also have a certain degree of adjustability to adapt to bags of different sizes and shapes.

[0009] Optionally, in a possible implementation manner, the mesh cover includes mounting blocks arranged at the top of the frame and a plurality of skeletons spaced apart and rotatably arranged on the mounting blocks, and mesh cloth is connected between adjacent two of the skeletons.

[0010] In the above technical solution, through a plurality of skeletons spaced apart and rotatably arranged on the mounting blocks and the mesh cloth connected between adjacent skeletons, the mesh cover forms a cover structure that can effectively block the diffusion of dust, and the mesh cover can be folded or unfolded according to actual needs, with flexible use. In addition, due to the flexible combination of the skeletons and the mesh cloth, the opening size, shape or density of the mesh cloth of the mesh cover can be adjusted according to the characteristics of different powders and the bagging requirements.

[0011] Optionally, in a possible implementation manner, there are two relatively and spaced-apart mounting blocks, the skeletons are in an arc structure, and both ends of the skeletons are rotatably arranged on the two mounting blocks respectively.

[0012] In the above technical solution, the setting of the two mounting blocks provides a more stable support point for the skeletons. The double-point support method not only increases the stability of the skeletons on the mounting blocks but also reduces the distortion or deformation generated by the skeletons when stressed, thus ensuring the stability and durability of the overall structure of the mesh cover. The arc-structured skeleton design enables the mesh cover to form a larger protection area when unfolded.

[0013] Optionally, in a possible implementation manner, the hopper is a gradually changing conical structure with a larger upper part and a smaller lower part.

[0014] In the above technical solution, the conical structure design makes the internal space of the hopper gradually shrink. This shape helps to guide the powder to flow smoothly downward, reducing the retention and accumulation of powder in the hopper. In this way, not only the bagging efficiency is improved, but also the risk of shutdown caused by powder blockage is reduced.

[0015] Optionally, in a possible implementation manner, a notch is provided on the side of the hopper near the bottom opening, and a clamping plate for closing the bottom opening is movably inserted at the notch.

[0016] In the above technical solution, the design of the clamping plate allows the operator to flexibly control the size of the bottom opening of the hopper or completely close the opening according to needs. When it is necessary to pause bagging to adjust the position of the packaging bag or replace an empty bag, the operator can quickly insert the clamping plate to close the opening and prevent the powder from flowing out continuously.

[0017] Optionally, in a possible implementation, a flange is provided at the bottom opening, the flange extends towards the center of the bottom opening, and the clamping plate can be placed on the flange.

[0018] In the above technical solution, the design of the flange provides a stable supporting surface for the clamping plate, enabling the clamping plate to fit more closely on the hopper when closing the bottom opening, thereby enhancing the sealing performance. In addition, the flange extending towards the center of the bottom opening not only provides support for the clamping plate but also increases the stability of the bottom structure of the hopper, helping to disperse the pressure of the powder on the bottom opening and prevent deformation or damage caused by excessive pressure.

[0019] Optionally, in a possible implementation, multiple groups of positioning rings are provided on the outer periphery of the hopper, the multiple groups of positioning rings are spaced along the height direction of the hopper, and each group of positioning rings consists of a plurality of rings distributed in a circular pattern on the same horizontal plane.

[0020] In the above technical solution, the design of the positioning rings can be used to adapt to cloth bags with different opening sizes, that is, the cloth bag can be fixed at different positioning rings according to the actual bag mouth size, so as to effectively improve the applicable range of the device to meet different bagging requirements.

[0021] Optionally, in a possible implementation, the frame includes a main frame, multiple support columns fixed at the bottom of the main frame, and universal casters provided at the bottom of the support columns, and the hopper and the mesh cover are both arranged on the main frame.

[0022] In the above technical solution, the main frame serves as the core support structure of the entire device, ensuring that components such as the hopper and the mesh cover can be firmly installed and bear the weight and impact force of the powder. At the same time, multiple support columns are evenly distributed at the bottom of the main frame, further enhancing the load-bearing capacity and stability of the frame, reducing the shaking and tilting of the device during operation. And the universal casters provided at the bottom of the support columns enable the entire device to be easily moved and positioned, and the operator can quickly adjust the position of the device according to needs.

[0023] Optionally, in a possible implementation, the main frame is of a rectangular structure, there are four support columns located at the four corners of the main frame respectively, and strengthening columns are provided between adjacent two support columns, and the number of the strengthening columns is three.

[0024] In the above technical solution, the support columns distributed at the four corners and the additional strengthening columns jointly enhance the load-bearing capacity of the main frame, enabling the device to safely carry the weight of a large amount of powder materials and packaging bags without obvious deformation or damage. And the design of the three strengthening columns can, on the one hand, improve the strength of the support columns, and on the other hand, avoid completely enclosing the four support columns, that is, a gap is formed between two of the support columns to facilitate the placement of the cloth bag.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application to be protected, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0031] Please refer to Figure 1 and Figure 2, this embodiment provides an auxiliary device for powder bagging, including a movable frame 1, on which a blanking hopper 2, a foldable mesh cover 3, and a plurality of positioning components 4 are provided; the blanking hopper 2 has a top opening and a bottom opening, the mesh cover 3 is located above the blanking hopper 2, and when the mesh cover 3 is fully unfolded, it can block a part of the space above the top opening; the plurality of positioning components 4 are arranged around the outer periphery of the blanking hopper 2, and the positioning component 4 includes a limiting post 41 provided on the frame 1, a flexible lasso 42 clamped on the limiting post 41, and a hook 43 provided on the flexible lasso. The flexible lasso 42 can be a rope or a wire and other objects with a certain flexibility, which can be arbitrarily deformed to adapt to the bag ears of the cloth bag. The flexible lasso 42 can form a closed structure by means of a drawstring to be sleeved on the limiting post 41, or can be directly fixed on the limiting post 41.

[0032] When the device of this embodiment is in use, place the cloth bag below the blanking hopper 2, hook the bag ears of the cloth bag through the hook 43 in the positioning component 4, and under the action of the plurality of hooks 43, the bag opening of the cloth bag is opened, so that the bag opening is located at the bottom opening of the blanking hopper 2. In this way, the powder can be loaded into the blanking hopper 2 by a forklift or other tools and the powder can fall into the cloth bag smoothly, thereby completing the powder bagging. Therefore, there is no need to manually open the bag opening of the cloth bag, effectively reducing the use of manpower and improving the accuracy and efficiency of powder bagging.

[0033] Among them, the design of the movable frame 1 facilitates adjusting the position of the equipment according to production requirements, increasing the flexibility of production. The design of the top opening and the bottom opening of the blanking hopper 2 enables the powder to smoothly enter the bag, while the folding design of the mesh cover 3 protects the operator from directly contacting the dust and can also cover part of the top opening when necessary, reducing the dust flying.

[0034] In addition, the setting of the plurality of positioning components 4 ensures the stability of the bag during the bagging process and reduces the powder leakage caused by the offset of the bag position. And the positioning component 4 includes a limiting post 41, a flexible lasso 42 and a hook 43, which not only ensures the firmness of positioning but also has a certain adjustability and can adapt to bags of different sizes and shapes.

[0035] In this embodiment, the mesh cover 3 includes a mounting block 31 provided on the top of the frame 1 and a plurality of skeletons 32 spaced apart and rotatably provided on the mounting block 31, and a mesh cloth 33 is connected between adjacent two skeletons 32. Among them, adjacent two skeletons 32 can be connected by a mesh cloth 33, or the mesh cloth 33 can cover the plurality of skeletons 32, and the plurality of skeletons 32 are respectively fixed at different positions of the mesh cloth 33.

[0036] Through a plurality of skeletons 32 that are spaced apart and rotatably arranged on the mounting block 31, and a mesh cloth 33 connected between adjacent skeletons 32, the mesh cover 3 forms a cover structure that can effectively block the diffusion of dust, and the mesh cover 3 can be folded or unfolded according to actual needs, with flexible use. In addition, due to the flexible combination of the skeletons 32 and the mesh cloth 33, the opening size, shape of the mesh cover 3 or the density of the mesh cloth 33 can be adjusted according to the characteristics of different powder materials and the bagging requirements.

[0037] In this embodiment, there are two relatively and spaced-apart mounting blocks 31, the skeleton 32 is an arc-shaped structure, and both ends of the skeleton 32 are rotatably arranged on the two mounting blocks 31 respectively.

[0038] The arrangement of the two mounting blocks 31 provides a more stable support point for the skeleton 32. The double-point support method not only increases the stability of the skeleton 32 on the mounting block 31, but also reduces the distortion or deformation generated by the skeleton 32 when stressed, thereby ensuring the stability and durability of the overall structure of the mesh cover 3. The design of the arc-shaped skeleton 32 enables the mesh cover 3 to form a larger protection area when unfolded.

[0039] In this embodiment, the blanking hopper 2 is a gradually changing conical structure that is larger at the top and smaller at the bottom. Specifically, the blanking hopper 2 has four inclined sides, and a four-sided closed conical structure is formed by splicing the four sides together. The design of the conical structure makes the internal space of the blanking hopper 2 gradually contract. This shape helps to guide the powder material to flow smoothly downward, reducing the retention and accumulation of the powder material in the hopper. In this way, not only the bagging efficiency is improved, but also the risk of downtime caused by powder blockage is reduced.

[0040] In this embodiment, a notch is provided at the side of the blanking hopper 2 near the bottom opening, and a clamping plate 5 for closing the bottom opening is movably inserted at the notch. The part of the clamping plate 5 located inside the blanking hopper 2 can abut against the inner wall of the blanking hopper 2, and a handle is provided at one end of the clamping plate 5 located outside the blanking hopper 2 to facilitate the pulling of the clamping plate 5.

[0041] The design of the clamping plate 5 allows the operator to flexibly control the size of the bottom opening of the blanking hopper 2 or completely close the opening according to needs. When it is necessary to pause bagging to adjust the position of the packaging bag or replace an empty bag, the operator can quickly insert the clamping plate 5 to close the opening and prevent the powder material from flowing out continuously. In addition, by precisely adjusting the position of the clamping plate 5 in the notch, the operator can control the outflow speed and flow rate of the powder material, thereby improving the accuracy and rate of bagging.

[0042] In this embodiment, a flange 21 is provided at the bottom opening, and the flange 21 extends towards the center of the bottom opening. The clamping plate 5 can be placed on the flange 21. The flange 21 is essentially a platform formed by contracting towards the center of the bottom opening and can be used to support the clamping plate 5.

[0043] The design of the flange 21 provides a stable support surface for the clamping plate 5, enabling the clamping plate 5 to fit more closely to the blanking hopper 2 when closing the bottom opening, thereby enhancing the sealing performance. In addition, the flange 21 extends towards the center of the bottom opening, which not only provides support for the clamping plate 5 but also increases the stability of the bottom structure of the blanking hopper 2, helping to disperse the pressure of the powder on the bottom opening and preventing deformation or damage caused by excessive pressure.

[0044] In this embodiment, multiple groups of positioning rings 6 are provided on the outer periphery of the blanking hopper 2. The multiple groups of positioning rings 6 are spaced along the height direction of the blanking hopper 2, and each group of positioning rings 6 consists of a plurality of rings distributed in a circular pattern on the same horizontal plane. Components such as hooks or fixing straps can be provided on the positioning rings 6 for fixing or binding the ear of the cloth bag.

[0045] The design of the positioning rings 6 can be used to adapt to cloth bags with different opening sizes, that is, the cloth bag can be fixed at different positioning rings 6 according to the actual bag mouth size. In this way, the applicable range of the device can be effectively increased to meet different bagging requirements.

[0047] The main frame 11, as the core support structure of the entire device, ensures that components such as the blanking hopper 2 and the mesh cover 3 can be stably installed and bear the weight and impact force of the powder. At the same time, the multiple support columns 12 are evenly distributed at the bottom of the main frame 11, further enhancing the load-bearing capacity and stability of the frame 1, and reducing the shaking and tilting of the device during operation. The universal casters 13 provided at the bottom of the support columns 12 enable the entire device to be easily moved and positioned, and the operator can quickly adjust the position of the device according to needs.

[0048] In this embodiment, the main frame 11 is of a rectangular structure, there are four support columns 12 which are respectively located at the four corners of the main frame 11, and three strengthening columns 14 are provided between two adjacent support columns 12.

[0049] The support columns 12 distributed at the four corners and the additional strengthening columns 14 together enhance the load-bearing capacity of the main frame 11, enabling the device to safely carry the weight of a large amount of powder and packaging bags without obvious deformation or damage. And the design of the three strengthening columns 14 can, on the one hand, improve the strength of the support columns 12, and on the other hand, avoid completely enclosing the four support columns 12, that is, a gap is formed between two of the support columns 12 to facilitate the placement of the cloth bag.
