Description

Technical Field

[0001] This invention relates to the field of putty powder production, and more particularly to a putty powder production fly powder treatment device that can be quickly cleaned. Background Technology

[0002] In the putty powder production industry, the problem of dust pollution during the raw material feeding process has long plagued the industry's development. In the traditional production process, workers manually cut open the raw material bags (such as heavy calcium carbonate powder, lime calcium carbonate powder, etc.) and pour them into the hopper. During this process, because the powder inside the bag is in a compressed state, dust will be released instantly when the bag is broken. When pouring, the light and fine powder is very easy to fly up and form a "dust cloud". The spilled powder will be raised again during subsequent handling and cleaning, which will aggravate the pollution.

[0003] This open-type material feeding method poses multiple hazards: First, workers are exposed to high concentrations of dust for extended periods, making them highly susceptible to occupational diseases such as pneumoconiosis and chronic bronchitis, severely impacting their health. Second, the escape of dust results in a 2%-5% loss of raw materials, increasing production costs for enterprises. Third, dust adhering to equipment surfaces accelerates mechanical wear, leading to a more than 30% increase in equipment failure rates, further affecting production efficiency. Finally, frequent cleaning not only consumes significant manpower and resources but also significantly reduces overall production efficiency. Currently, various solutions exist on the market to address dust pollution, but these solutions generally have shortcomings. For example, while ordinary ventilation systems can partially collect dust, their collection efficiency is less than 40%, and they are prone to causing secondary pollution during cleaning. Automatic packaging machines, while highly effective at dust removal, are prohibitively expensive for many small workshops. Simple dust collection devices, although low-cost, suffer from inconvenient maintenance and cleaning difficulties in practical use, failing to meet the needs of high-efficiency production.

[0004] Therefore, there is an urgent need for an economical, simple, and easy-to-maintain powder handling device to meet the specific needs of small workshops. Summary of the Invention

[0005] In order to overcome the shortcomings of existing fly powder treatment equipment, such as low collection efficiency, inconvenient cleaning, complex structure or high cost, which make it difficult to popularize and apply in small workshops, the technical problem is to provide a fly powder treatment equipment for putty powder production that can be cleaned up quickly.

[0006] The technical solution is as follows: A quick-cleaning putty powder production fly powder treatment device, including a feeding component with a discharge port on its bottom wall, a conveyor at the discharge port of the feeding component, a sealing cover on the feeding component to control the opening and closing of its inlet, a support frame slidably connected inside the feeding component, two parallel fixed rods in the middle of the support frame, anti-slip rubber sleeves on the surface of the fixed rods to stably support bagged raw materials, symmetrically distributed return springs connecting the support frame and the feeding component, and a guide component fixed inside the feeding component with a cutting assembly on it.

[0007] Furthermore, the cutting assembly includes sliders symmetrically slidably connected to the guide, and each slider is slidably connected to a cutting element. The cutting element is made of high-strength alloy steel, and each cutting element is connected to an adjacent slider by symmetrically distributed compression springs, which are all wound around the adjacent cutting element.

[0008] Furthermore, the support frame is provided with symmetrically distributed sliding members, which are located outside the fixed rod. The two have a height difference, forming a stepped support structure that is low in the middle and high on both sides.

[0009] Furthermore, the support frame is fixed with symmetrically distributed guide frames, each guide frame is provided with symmetrically distributed inclined grooves, and each slider is fixed with a fixed column, which is located directly below the opening of the inclined groove of the guide frame. Rolling bearings are installed at the ends of each fixed column to ensure smooth rolling in the inclined groove.

[0010] Furthermore, a pin is slidably connected to the side wall of the feeding component, and a tension spring is connected between the pin and the feeding component. The tension spring is wound around the pin to provide a reset force. The support frame has a positioning hole on the side near the pin. By cooperating with the pin and the positioning hole, the position of the support frame can be stably locked.

[0011] Furthermore, the inner wall of the feeding component is provided with symmetrically distributed winding reels, each of which is equipped with a high-elasticity spiral spring. One end of the spiral spring is fixed to the hollow column in the center of the winding reel, and the other end is connected to the pull rope. The movable ends of the two pull ropes at the same horizontal position are respectively fixed to the adjacent sliding parts. The two sliding parts are connected by symmetrically distributed opening springs, which are all wound around the support frame.

[0012] Furthermore, each support frame is fixed with a positioning block near the corner, and each block has an arc-shaped through hole inside, through which the movable end of each pull rope passes.

[0013] Furthermore, each of the symmetrically distributed sliding members is slidably connected to a separating member. Each separating member is connected to an adjacent sliding member by a symmetrically distributed linear spring. These linear springs are all wound around the adjacent separating members. Each separating member is provided with evenly distributed protrusions. Symmetrically distributed corrugated blocks are fixed to the support frame. Each separating member has symmetrically distributed convex strips at both ends, and the convex strips slide on the adjacent corrugated blocks.

[0014] Furthermore, a guide frame is fixedly connected to the feeding component, and symmetrically distributed sealing components are slidably connected to it. The sealing components slide within the side wall of the feeding component, and a storage spring is connected between the symmetrically distributed sealing components and the guide frame, which is wound around the guide frame.

[0015] Furthermore, the closure is located between the support frame and the cutting component. The support frame is provided with symmetrically distributed triangular blocks, and the sides of the closure that are close to each other are provided with symmetrical inclined surfaces, which are used to cooperate with the guide frame and the triangular blocks to achieve automatic opening and closing.

[0016] Beneficial effects: This invention achieves efficient and dust-free production through a closed feeding system and multi-stage linkage mechanism. Its innovative cutting component adopts a two-stage elastic buffer design, combined with a dynamic expansion mechanism, which can cut the packaging bag into a strip-shaped unloading port, shortening the unloading time of a single bag and reducing the residue rate. The support frame is equipped with an intelligent locking and wave block vibration system to ensure stable placement of raw materials and thorough unloading. The combination of the sealing component and the dust collection device forms a double dust barrier, effectively preventing dust from escaping. The overall design significantly improves feeding efficiency through the synergistic effect of gravity drive and mechanical linkage, while reducing the intensity of manual intervention, realizing continuous automated operation, and combining environmental protection and economy.

Detailed Implementation

[0023] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0024] Example 1: A quick-cleaning dust removal device for putty powder production, such as... Figure 1 and Figure 2 As shown, the device includes a feeding component 1 with a discharge port on its bottom wall. A conveyor 11 is provided at the discharge port of the feeding component 1 to transport the raw materials into the mixing tank for mixing and achieving dust-free conveying. The feeding component 1 is provided with a sealing cover 12 to control the opening and closing of its inlet, which is used to seal the feeding component 1. The sealing cover 12 is hinged to the feeding component 1 by a hinge. After feeding is completed, the sealing cover 12 closes to seal the feeding component 1, effectively preventing dust from drifting out of the feeding component 1, improving the production environment, and reducing dust pollution.

[0025] The feeding component 1 is slidably connected to a support frame 2. The support frame 2 has two parallel fixed rods 201 in the middle. The surface of the fixed rods 201 is provided with anti-slip rubber sleeves, which can stably support the bagged raw materials and prevent the bagged raw materials from sliding or tipping on the support frame 2. The support frame 2 and the feeding component 1 are connected by symmetrically distributed return springs 29, which are wound around the support frame 2.

[0026] When the weight of the raw material on the support frame 2 is lost, the return spring 29 can automatically bounce the support frame 2 back to the initial position, making it easy to receive the raw material next time; the feeding component 1 is fixedly connected to the guide component 25, which is equipped with a cutting component. When the support frame 2 carrying bagged raw material descends to contact the cutting component, it can quickly break open the packaging bag containing the raw material, so that the raw material can smoothly leak out from the broken part, realizing automatic unloading in a closed space, reducing the workload of manual bag opening and improving production efficiency.

[0027] This closed-loop feeding system is based on the principles of gravity drive and mechanical linkage, achieving dust-free feeding through automatic cutting and sealed conveying. During operation, the closed cover 12 is opened, the bagged raw materials are placed flat on the anti-slip fixing rod 201 of the support frame 2, and then the closed cover 12 is closed to form a sealed space.

[0028] The weight of the bagged raw material forces the support frame 2 to slide downwards, and the return spring 29 will stretch. When the support frame 2 descends to the set position of the guide 25, the cutting component on it will come into contact with the bagged raw material, and the cutting component will pierce the packaging bag to form a leakage opening.

[0029] The raw material falls through the discharge opening, and the conveyor 11 then uniformly transports the material to the mixing tank for mixing. As the raw material continues to flow out, the load on the support frame 2 is reduced, and the return spring 29 releases its elastic potential energy, pushing the support frame 2 upward to reset, raising the empty packaging bag to the operating height. At this time, the sealing cover 12 is opened, and the empty bag is manually removed. The above process can then be repeated to achieve continuous, automated, and sealed feeding.

[0030] Specifically, the cutting assembly adopts a two-stage elastic buffer structure design, including sliders 26 symmetrically slidably connected to the guide member 25. A linear guide pair is provided between the sliders 26 and the guide member 25 to ensure sliding accuracy. Each slider 26 is slidably connected to a cutting element 27. The cutting element 27 is made of high-strength alloy steel, and the cutting edge is vacuum quenched with a Rockwell hardness ≥ HRC58. Symmetrically distributed compression springs 28 are connected between the cutting element 27 and the adjacent slider 26. The symmetrically distributed compression springs 28 are all wound around the adjacent cutting element 27 to form a coaxial elastic buffer structure.

[0031] When the bagged material moves downward with the support frame 2 and contacts the tip of the cutting element 27, the wedge-shaped cutting edge of the cutting element 27 cuts into the packaging bag at an acute angle of ≥30°. As the bagged material continues to move downward, the cutting element 27 slides downward relative to the slider 26, and the compression spring 28 undergoes elastic deformation, storing elastic potential energy. When the compression spring 28 reaches 80% of its designed stroke, the cutting edge of the cutting element 27 completely cuts into the packaging bag, forming the initial discharge port.

[0032] At this point, the gravitational potential energy of the bagged material is transferred to the cutting assembly through the support frame 2, forcing the slider 26 to slide in opposite directions along the guide rail pair of the guide member 25, so that the symmetrically distributed cutting members 27 perform an expansion cut on the packaging bag. When the weight of the bagged material overcomes the maximum elastic resistance of the compression spring 28, the cutting member 27 rebounds instantaneously under the action of the spring force, allowing the cutting member 27 to be inserted from the tip of the blade until the entire blade body enters the packaging bag, forming a long strip-shaped discharge port. This design achieves dynamic adjustment of the cutting depth through the instantaneous release of elastic potential energy, ensuring that packaging bags of different materials can form an effective discharge opening, improving discharge efficiency and reducing residue rate.

[0033] The support frame 2 is equipped with a symmetrically distributed sliding adjustment mechanism, including a sliding member 21 that is slidably connected along the crossbeam of the support frame 2. When bagged raw materials are placed, the bottom of the bag simultaneously contacts the supporting plane of the sliding member 21 and the fixing rod 201 of the support frame 2. The sliding member 21 is located outside the fixing rod 201, and the height difference between the two is 25-35mm, forming a stepped support structure that is low in the middle and high on both sides.

[0034] When the bagged raw material is placed on the sliding member 21, its own weight causes the center to form a downward-concave parabolic surface with a depth of 20-50mm. The fixing rod 201 provides point support for the concave part. This structural design allows the raw material to naturally converge towards the center under the action of gravity, forming a potential energy gradient centered on the cutting point.

[0035] When the bottom of the packaging bag is cut open by the cutting piece 27, the raw material, under its own weight and the lateral force generated by the height difference on both sides, forms a flow slope angle of ≥30°, causing the raw material on both sides to converge towards the central discharge port at a flow velocity of ≥0.8m / s, achieving rapid emptying of the entire cross-section of material. Actual measurements show that this structure can shorten the unloading time to less than 60% of traditional planar support structures, and reduce the residual amount to less than 1%.

[0036] During the feeding process of bagged raw materials, due to the characteristics of the bag material and the design limitations of the cutting component 27, relying solely on the gravity of the bagged raw materials pressing on the cutting component 27 presents the following problems: the cutting kerf size is fixed by the blade size, typically ≤50mm, and cannot be dynamically adjusted according to the material characteristics; the angle of repose of the putty powder is ≥40°, easily forming an arching effect at the discharge port, leading to interruption of unloading; the unloading time for large bags is ≥2 minutes / bag, restricting the production line capacity. Therefore, it is necessary to design a mechanism that allows the cutting component to move relative to the bag to enlarge the opening at the bottom of the bag, thereby significantly improving the discharge speed of the bagged raw materials.

[0037] like Figure 2 As shown, specifically, the support frame 2 is fixedly connected to symmetrically distributed guide frames 22, each guide frame 22 is provided with symmetrically distributed inclined grooves, and each slider 26 is fixedly connected to a fixed post 261, which is connected to the slider 26 by an interference fit. They are all located directly below the opening of the inclined groove of the guide frame 22. Each fixed post 261 is equipped with a rolling bearing at its end. The outer diameter of the bearing is 0.1-0.2mm away from the width of the inclined groove to ensure smooth rolling in the inclined groove.

[0038] When the bagged raw material presses down on the support frame 2, the support frame 2 drives the guide frame 22 to move down synchronously. Its inclined groove contacts the fixed column 261 of the slider 26. According to the principle of inclined plane motion conversion, the vertical displacement of the guide frame 22 is converted into the horizontal displacement of the slider 26 through the 45° inclined groove, driving the cutting part 27 to perform a transverse pulling motion, expanding the initial puncture opening into a strip opening with a length ≥300mm. This "puncture first, then pulling" composite cutting trajectory greatly expands the effective flow area of ​​the unloading port, forming a full-section material flow channel.

[0039] As the raw material decreases, the return spring 29 pushes the support frame 2 to reset, and the guide frame 22 drives the cutting component to move inward and return to its original position via the inclined groove. The entire process achieves the following: the discharge port area is automatically adjusted according to the material characteristics; powder bridging is eliminated, reducing the residue rate; the cutting component automatically resets without manual intervention; and the unloading time of a single bag is shortened, significantly improving the production efficiency of small and medium-sized putty powder enterprises.

[0040] The existing putty powder feeding equipment suffers from a problem of uncontrolled movement of the support frame 2: the support frame 2 is supported only by the return spring 29. When bagged raw materials are placed on it, the excessive weight of the materials causes the support frame 2 to descend rapidly. During this process, workers lack sufficient time to level and arrange the bagged raw materials, easily resulting in non-standard placement states such as tilting or standing upright. This causes the cutting part 27 to fail to form an ideal discharge port, leading to insufficient material leakage, reduced feeding efficiency, and affecting the stability of equipment operation and the consistency of discharge effect.

[0041] Therefore, a mechanism for locking the support frame 2 needs to be designed so that the support frame 2 can only move downwards after the workers have finished sorting the bagged raw materials.

[0042] like Figure 2 As shown, specifically, a pin 23 is slidably connected to the side wall of the feeding component 1 for locking the position of the support frame 2. A tension spring 24 is connected between the pin 23 and the feeding component 1, and the tension spring 24 is wound around the pin 23 to provide a reset force. The support frame 2 has a positioning hole on the side near the pin 23. The position of the support frame 2 can be stably locked by the cooperation of the pin 23 and the positioning hole. In addition, the bottom of the pin 23 is provided with a guide slope for automatic reset and locking during the upward movement of the support frame 2.

[0043] In the initial state, the pin 23 is inserted into the positioning hole of the support frame 2 under the action of the tension spring 24, and the support frame 2 is locked in the initial position by mechanical limiting. After the worker places the bagged raw materials on the support frame 2, the support frame 2 will not fall due to the weight of the raw materials because of the locking action of the pin 23, and the worker can flatten and arrange the bagged raw materials.

[0044] After the arrangement is completed, the worker pulls the pin 23 outward to overcome the spring tension and disengage it from the insertion hole. At this time, the support frame 2 is unlocked and moves downward under the gravity of the raw material. After the pin 23 is released, the tension spring 24 immediately drives the pin 23 to reset and maintain the standby state.

[0045] When the raw material is unloaded, the return spring 29 pushes the support frame 2 to move upward. During the upward movement, the upper surface of the support frame 2 contacts the 30° guide slope at the bottom of the pin 23. Through the mechanical transmission of the slope, the pin 23 is pushed outward, and the tension spring 24 stores energy again.

[0046] When the support frame 2 rises to the alignment of the positioning socket and the pin 23, the spring releases energy, driving the pin 23 to quickly insert into the socket, completing the automatic reset and locking of the support frame 2, and preparing for the next feeding. This locking control mechanism realizes both manual intervention and automatic reset of the support frame 2's movement, ensuring that the bagged raw materials are cut and unloaded in the best condition, significantly improving feeding efficiency and unloading quality.

[0047] Existing putty powder feeding equipment suffers from incomplete unloading when processing large-sized bagged raw materials: when the bagged raw material exceeds the distance between the sliding parts 21, the unloading port cut by the cutting part 27 at the bottom center axis of the bag can only discharge the raw material in the middle of the bag. As the middle raw material flows out, the raw material on the front and back sides of the bag that exceeds the sliding parts 21 hangs down due to gravity, forming a "stuffed bag"-like accumulation. This causes a drop in height between this part of the raw material and the unloading port, preventing it from flowing out smoothly by gravity. This phenomenon increases the raw material residue rate, requiring secondary manual cleaning, reducing production efficiency and increasing labor intensity, while also affecting the continuity of equipment automation.

[0048] like Figure 3 As shown, specifically, the inner wall of the feeding component 1 is provided with symmetrically distributed functional winding coils 3, each of which is equipped with a high-elasticity spiral spring. One end of the spiral spring is fixed to the hollow column in the middle of the winding coil 3, and the other end is connected to the pull rope 31. The movable ends of the two pull ropes 31 at the same horizontal position are respectively fixed to the adjacent sliding component 21 to realize the function of dynamically controlling the outward movement of the sliding component 21.

[0049] Furthermore, the two sliding members 21 are connected by symmetrically distributed opening springs 3102, which are all wound around the support frame 2 to ensure that the distance between the sliding members 21 can be flexibly adjusted. The support frame 2 is fixedly connected to positioning blocks 3101 near the corners, each with an arc-shaped through hole inside. The movable end of each pull rope 31 passes through the adjacent positioning block 3101, thereby achieving precise guidance of the pull rope 31.

[0050] After the bagged raw materials are placed on the support frame 2, the support frame 2 and the sliding member 21 move down synchronously under the action of gravity. The sliding member 21 pulls the rope 31, causing the spiral spring in the winding device 3 to gradually store energy. When the guide frame 22 slides into contact with the fixed column 261, triggering the cutting assembly to extend the cutting laterally, the rope 31 is released to its maximum stroke.

[0051] At this time, the sliding member 21 continues to move downwards, and the taut pull rope 31 overcomes the preload of the opening spring 3102, driving the sliding member 21 to move outwards along the guide rail of the support frame 2, simultaneously lifting the raw materials hanging down on both sides of the bag. Guided by the arc-shaped through hole of the positioning block 3101, the pull rope 31 pulls the sliding member 21 with a constant tension, so that the front and rear sides of the bagged raw materials maintain an inclination angle difference of ≥5° with the discharge port, ensuring that this part of the raw materials continues to flow to the discharge port under the action of gravity.

[0052] As the raw material is emptied, the return spring 29 pushes the support frame 2 to rise, and the slack pull rope 31 automatically rewinds under the action of the spiral spring. At the same time, the opening spring 3102 drives the sliding part 21 to reset inward, completing the mechanism cycle. This realizes the dynamic adaptive adjustment of the sliding part 21 during the unloading of large-sized bagged raw materials, which can reduce the unloading residue rate and significantly improve the feeding efficiency and automation level.

[0053] Existing putty powder feeding equipment suffers from high raw material residue during unloading: because the cutting openings are concentrated along the central axis of the bag bottom, raw materials far from the openings, especially fine powdery materials adhering to the plane of the sliding component 21 and the inner wall of the bag, cannot flow out by gravity due to a lack of effective drive. Simultaneously, the planar structure of the sliding component 21 cannot effectively disturb the raw materials, leading to increased residue after unloading. This not only wastes materials and increases production costs but also requires secondary manual cleaning, reducing production efficiency and affecting the equipment's ability to operate automatically and continuously.

[0054] Specifically, slidable separators 33 are connected to the symmetrically distributed sliding members 21 for receiving bagged raw materials. Symmetrically distributed linear springs 34 are connected between each separator 33 and an adjacent sliding member 21. These linear springs 34 are wound around the adjacent separators 33. Each separator 33 has evenly distributed protrusions so that when the bagged raw material is placed on the separator 33, the protrusions can push the raw material upwards, increasing the height difference between the raw material and the opening cut by the cutting member 27. Because the height difference is increased, the raw material in the bag is more likely to flow out from the opening. Symmetrically distributed corrugated blocks 32 are fixed to the support frame 2. Symmetrically distributed protrusions are provided at both ends of each separator 33. The protrusions slide on the adjacent corrugated blocks 32 to achieve the up-and-down reciprocating movement of the separator 33.

[0055] When the slider 21 moves outward, the separator 33 moves outward synchronously. During this process, the protrusions at both ends of the separator 33 interact with the wave block 32: when the protrusions contact the crests of the wave block 32, the separator 33 is lifted upward by the wave block 32 through the protrusions, achieving upward displacement relative to the slider 21, at which time the linear spring 34 undergoes elastic deformation. When the protrusions contact the troughs of the wave block 32, under the elastic force of the linear spring 34, the separator 33 returns to its original position downward, completing downward sliding relative to the slider 21.

[0056] As the separator 33 continues to slide on the corrugated block 32, its overall structure reciprocates up and down. The evenly distributed protrusions on the separator 33 vibrate up and down accordingly, transmitting the vibration to the raw material inside the bag through the bag body. This vibration mechanism ensures that the raw material on both sides of the bag vibrates synchronously as the sliding member 21 moves outward. This not only significantly accelerates the outflow speed of the raw material inside the bag, but also effectively shakes off the raw material far from the cut opening and adhering to the inner wall of the bag, thereby greatly improving the cleanliness of the bagged raw material unloading, reducing raw material residue, and avoiding waste.

[0057] Example 2: In the putty powder production process, the time from when the bagged raw material is placed to when it is cut open and then to when the raw material flows out of the bag is relatively short. However, at the moment the cutter 27 cuts open the bagged raw material, a large amount of dust is released due to the compressed state of the powder inside the bag. Even though the sealing cap 12 is closed, the dust will still drift inside the feeding device 1. When the sealing cap 12 is opened to remove the empty bag and a new bagged raw material is put in, the dust inside the feeding device 1 has not completely settled, and some dust will drift out through the open sealing cap 12, causing the problem described in the background art.

[0058] Therefore, a partition mechanism needs to be set up in the feeding component 1 to seal the space inside the feeding component 1 when the bagged raw material is about to be cut by the cutting component 27, reduce dust emission, ensure a dust-free working environment, protect workers' health, avoid raw material waste, and improve production efficiency.

[0059] like Figure 4 and Figure 5 As shown, specifically, a guide frame 42 is fixedly connected to the feeding component 1, and symmetrically distributed sealing components 4 are slidably connected to it. The sealing components 4 slide within the side wall of the feeding component 1, serving as a dynamic barrier; a storage spring 41 is connected between the symmetrically distributed sealing components 4 and the guide frame 42, which is wound around the guide frame 42 to provide reset power.

[0060] In addition, the sealing component 4 is located between the support frame 2 and the cutting component 27. The support frame 2 is provided with symmetrically distributed triangular blocks, and the sealing component 4 has symmetrically arranged inclined surfaces on the sides that are close to each other, which are used to cooperate with the guide frame 22 and the triangular blocks to achieve automatic opening and closing. The inner wall of the sealing cover 12 is provided with a dust collection device to absorb the small amount of residual dust in the upper part of the feeding component 1, further improving the dust-free effect.

[0061] In the putty powder production process, the bagged raw materials are placed, cut and poured as follows: The bagged raw materials are placed on the support frame 2, and the sealing part 4 is closed under the action of the storage spring 41, which isolates the upper and lower space inside the feeding part 1.

[0062] As the guide frame 22 moves downward with the support frame 2, it contacts the upper inclined surface of the closure 4, forcing the closure 4 to move outward and open, causing the storage spring 41 to deform. When the support frame 2 and the bagged material on it pass the closure 4, under the elastic force of the storage spring 41, the closure 4 quickly closes inward, blocking the lower space inside the feeding component 1. At this time, the cutting component 27 penetrates into the bagged material, and through the cooperation of the guide frame 22 and the fixed column 261, the cutting component 27 moves outward to cut the bag open, allowing the material inside to flow out.

[0063] After the raw material overflows from the bag, the support frame 2 moves the guide frame 22 upward to reset. The triangular block on the support frame 2 contacts the lower inclined surface of the closure 4, squeezing the closure 4 outward through the triangular block, and the storage spring 41 deforms again. When the guide frame 22 passes the closure 4, under the elastic force of the storage spring 41, the closure 4 quickly closes inward, restoring the isolation state.

[0064] Although a small amount of dust may drift into the upper part of the feeding component 1 during the opening and closing of the closure 4, the dust collection device on the closure cover 12 can promptly absorb this dust, ensuring that there is no obvious dust residue inside the feeding component 1. Finally, when the support frame 2 moves upward and resets, and the closure cover 12 is opened to remove the empty bag and put in a new bag of raw materials, no more dust will drift out of the feeding component 1, achieving a dust-free working environment. This design effectively protects worker health, avoids raw material waste, reduces equipment maintenance frequency, and significantly improves overall production efficiency.

[0065] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention. Therefore, the scope of the invention should be limited only by the appended claims.
