[0002] In the raw material batching process for photovoltaic glass, materials are typically stored in silos to ensure continuous production. Materials fall from a hopper into a lower flow pipe and are then fed into an electronic scale for weighing and proportioning via a screw feeder. In related technologies, materials are usually packaged in woven bags and inner liner. During production, debris such as the woven ropes from the inner liner and bags easily gets mixed into the silo and enters the screw feeder along with the materials. This debris can easily become entangled or adhere to the screw rod and blades, causing abnormal feeding, poor discharge, or blockages, and may also increase the load on the screw feeder's drive motor. Prolonged overload operation carries the risk of motor damage or screw rod deformation, disrupting normal production and increasing equipment maintenance costs and operational burden.

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] In the raw material batching process, materials are typically stored in silos to ensure the supply needs of continuous production. Hoppers are connected to the silos; materials fall from the hoppers into the lower flow pipes and are then fed into an electronic scale by a screw feeder for weighing and proportioning. In related technologies, materials are usually packaged in woven bags and inner liner. During production, when unpacking, the woven bags are prone to tearing and abrasion, resulting in fragments or detached ropes. The inner liner may also break or leave residue due to insufficient toughness. During manual or mechanical feeding, these broken and residual debris are difficult to completely separate and easily fall into the silo along with the material.

[0026] The feed channel of the flow tube and screw feeder cannot prevent debris from entering the equipment with the material flow. This debris is mostly flexible fiber or sheet-like structure; the winding and adsorption forces generated by the rotating screw cause it to firmly adhere to the surface of the rod and blades. Furthermore, it continues to entangle and accumulate during material conveying, making it difficult to detach on its own. This not only causes abnormal feeding, poor discharge, or blockages, but may also increase the load on the screw feeder's drive motor. Prolonged overload operation carries the risk of motor damage or screw deformation, disrupts normal production, and increases equipment maintenance costs and operational burden.

[0027] Therefore, such as Figure 1 and Figure 2 As shown, the material discharge pipe proposed in this utility model includes: a pipe body 100, a rotating component 200, and a drive assembly 300. A cover plate 110 is provided on the outer wall of the pipe body 100. The rotating component 200 passes through the pipe body 100, and at least part of the rotating component 200 is located inside the pipe body 100. The rotating component 200 has a cylindrical structure, and an anti-jamming mechanism 210 is provided on its outer wall. The anti-jamming mechanism 210 is used to cut debris and materials. The cover plate 110 can be opened to clean the anti-jamming mechanism 210, providing convenience for handling residual debris and helping to reduce maintenance costs and operational burden. The drive assembly 300 is located on the outside of the pipe body 100 and is connected to the rotating component 200. The drive assembly 300 is used to drive the rotating component 200 to rotate, and the rotating component 200 drives the anti-jamming mechanism 210 to rotate. The anti-jamming structure can cut off debris such as woven bag ropes and inner liner mixed with the material during the feeding process. It can also break up clumps of material, reducing the risk of debris entanglement and adhesion on the surface of the screw rod or blades. This reduces abnormal discharge or blockage caused by debris blockage, reduces the load on the drive motor, and avoids equipment damage or screw rod deformation problems that may be caused by overload operation.

[0028] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the anti-jamming mechanism 210 includes a hook-and-loop fastener 211 and a cutting element 212. The hook-and-loop fastener 211 is made of corrosion-resistant and wear-resistant steel reinforcement. The hook-and-loop fastener 211 is used to hook up debris, intercepting and securing the inner liner and woven bag ropes during material feeding. The cutting element 212 is used to cut debris and materials. The cutting element 212 works in conjunction with the hook-and-loop fastener 211 to cut debris into easily dischargeable segments or small fragments, preventing entanglement and accumulation. Furthermore, the cutting element 212 can also act on clumps of material, breaking up large clumps through the shearing and impact forces generated by its rotation, facilitating subsequent conveying, reducing the risk of jamming, and ensuring smooth material transport.

[0029] In some other embodiments of this utility model, the rotating component 200 is a shredding shaft, and there are two rotating components 200. The driving assembly 300 includes a first driving component and a second driving component. The first driving component and the second driving component drive the two rotating components 200 to rotate in opposite directions, respectively. The anti-jamming mechanism is a shredding blade, which is fixedly and alternately arranged on the outer periphery of the shredding shaft. The shredding shaft achieves its cutting function through the meshing of the blade teeth, and is used to break up clumps of materials and debris such as woven bags and inner linings. The gap between the blade teeth of the shredding shaft can block large pieces of debris that have not been cut, thus intercepting the debris. It can be understood that the particle size of the material after cutting can be controlled by adjusting the blade shaft gap, changing the blade type, adjusting the rotation speed, etc. By cutting debris and clumps of materials into easily discharged segments or small fragments by the shredding blade, it is convenient for subsequent conveying, prevents entanglement and accumulation, reduces the risk of jamming, and ensures the smoothness of material conveying.

[0030] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, multiple hook-and-loop fasteners 211 and cutting elements 212 are provided, and they are alternately spaced along the length of the rotating component 200. The number of hook-and-loop fasteners 211 and cutting elements 212 can increase with the length of the pipe, forming a continuous processing area within the length of the pipe body 100, avoiding blind spots in debris interception and material breakage. When the rotating component 200 drives the hook-and-loop fasteners 211 and cutting elements 212 to rotate synchronously, after the hook-and-loop fasteners 211 hook onto the debris, the cutting elements 212 can quickly cut and decompose the debris, ensuring efficient removal of debris and uniformly breaking up clumps of material along the way, improving the anti-jamming effect.

[0031] Specifically, in some embodiments of this utility model, the cutting component 212 is a reamer with an arc-shaped blade, capable of efficiently shearing flexible debris and breaking up clumps of material, and generating stronger shearing force when rotating. The hook component 211 is a hook that can quickly catch debris such as braided rope and inner liner fragments, preventing the debris from falling off under the impact of the material flow. It is understood that the hook component 211 can also be a pawl, claw-shaped component, or comb-shaped hook, etc., with interception and hooking functions, and the cutting component 212 can also be a cutting tooth or blade, etc., with shearing and breaking functions.

[0032] Furthermore, in some other embodiments of this utility model, the hooks and the reamers are arranged alternately in a spiral pattern along the axial direction of the rotating component 200. When the material flows along the axial direction of the pipe body 100, the spirally arranged hooks can hook onto scattered braided ropes, inner liner fragments, and other debris from different angles. Subsequently, the adjacent reamers simultaneously cut the debris fixed by the hooks. The alternating spiral structure makes the force on the rotating component 200 more even when it is running, and it can guide the cut debris and crushed material to move smoothly with the material flow during the rotation process, preventing local accumulation.

[0033] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the outer wall of the tube body 100 is detachably connected to a first fixing plate 120 and a second fixing plate 130. The first fixing plate 120 and the second fixing plate 130 are respectively disposed on both sides of the tube body 100. One side of the rotating member 200 is rotatably connected to the first fixing plate 120, and one side of the rotating member 200 is provided with a snap-fit ​​part, the size of which is larger than that of the rotating member 200. The rotating member 200 is rotatably connected to the snap-fit ​​part, and the other side of the rotating member 200 is snapped to the second fixing plate 130, that is, the snap-fit ​​part is snapped to the second fixing plate 130. The snap-fit ​​part can fix one side of the rotating member 200 to the tube body 100. It should be noted that the first fixing plate 120 and the second fixing plate 130 are fixed to the outer wall of the pipe body 100 by fasteners. When components such as reamers and hooks need to be inspected, repaired or replaced, the fasteners on the first fixing plate 120 and the second fixing plate 130 can be removed to take the rotating part 200 out of the pipe body 100. There is no need to disassemble the entire pipe body 100 structure. The operation is convenient and can effectively shorten maintenance time and reduce maintenance costs.

[0034] In some embodiments of this utility model, such as Figure 1As shown, a fixing block 140 is provided inside the pipe body 100, and the fixing block 140 is fixedly connected to the pipe body 100. There are two fixing blocks 140, which are symmetrically arranged on both sides of the rotating component 200. The second fixing plate 130 is fixedly connected to the pipe body 100 by fasteners. The fixing block 140 has a threaded connection hole inside, and the fastener is threadedly connected to the fixing block 140. The fastener is a bolt. The fixing block 140 and the fastener cooperate to firmly lock the second fixing plate 130 to the outer wall of the pipe body 100, ensuring that the second fixing plate 130 limits and fixes the rotating component 200, and preventing the rotating component 200 from shifting or shaking when it rotates at high speed.

[0035] In some embodiments of this utility model, such as Figure 2 As shown, the cover plate 110 is equipped with a handle 111, which can be pulled to open and close the cover plate 110 for easy operation. There are two cover plates 110, which are symmetrically arranged on both sides of the pipe body 100. The cover plates 110 are rotatably connected to the pipe body 100 by hinges. The side of the cover plate 110 away from the hinge is equipped with a buckle, which can be locked and fixed to the pipe body 100. The buckle fixation ensures the airtightness of the pipe body 100 when the cover plate 110 is closed, preventing material leakage or debris from entering the pipe body 100. The symmetrically arranged cover plates 110 on both sides can expand the cleaning opening range, allowing the woven bags and inner liner wrapped around the hooks, reamers, and rotating parts 200 to be removed through the cover plates 110 for easy cleaning.

[0036] The feeding device according to an embodiment of the present invention includes a material discharge pipe, a screw conveyor 400, and a discharge component 500. The pipe body 100 is disposed between the screw conveyor 400 and the discharge component 500. The drive assembly 300 includes a driving component 310 and a driven component 320, which are connected by a drive belt 330. The driving component 310 drives the screw conveyor 400, and the driven component 320 drives the rotating component 200. The screw conveyor 400 has a screw inside. The driving component 310 can be a motor, which drives the screw to rotate. The drive belt 330 is a belt; after the motor starts, it drives the belt to rotate, and then the power is transmitted to the driven component 320 through the drive belt 330, which drives the rotating component 200 to rotate. The active component 310, in conjunction with the transmission belt 330, synchronously drives the screw conveyor 400 and the rotating component 200, eliminating the need for an additional independent power source and simplifying the overall structure.

[0037] According to the feeding device of this utility model embodiment, stable material feeding and conveying are achieved by adopting the material discharge pipe of this utility model embodiment. The transmission connection between the active component 310 and the driven component 320 enables the screw conveyor 400 and the rotating component 200 to operate synchronously. The anti-jamming mechanism 210 pre-processes debris and agglomerated materials, avoiding malfunctions in subsequent screw conveying and improving the service life of the equipment. At the same time, the convenient opening and closing of the cover plate 110 and the detachable fixing plate reduce the difficulty of equipment maintenance and component repair, reduce downtime maintenance time, ensure continuous and stable production, and combine practicality and reliability.

[0038] Furthermore, in a further embodiment of this utility model, the driving component 310 and the driven component 320 can also be connected by a chain drive, with the driving component 310 being a motor. The driving component 310 is equipped with a driving sprocket, and the driven component 320 is equipped with a driven sprocket. One end of the transmission chain is sleeved on the driving component 310, and the other end is sleeved on the driven component 320. While the driving component 310 drives the screw to rotate, it also drives the driven component 320 to rotate via the chain. One end of the rotating component 200 is fixedly connected to the driven component 320, and the driven component 320 drives the rotation of the rotating component 200. By using the driving component 310 in conjunction with the transmission belt 330 for transmission, no additional independent power source is required, simplifying the overall structure.

[0039] Reference Figure 3 In this embodiment of the invention, a discharge pipe 410 is provided on the side of the screw conveyor 400 away from the pipe body 100, and the discharge pipe 410 is adapted to the discharge end size of the screw conveyor 400. After being pushed and stirred by the screw blades of the screw conveyor 400, the material reaches the discharge end and enters the discharge pipe 410 under the axial thrust of the blades. The outlet end of the discharge pipe 410 can be adapted to connect to storage equipment, the next conveying link, or a processing station according to the requirements of subsequent processes, so as to realize the directional and orderly flow of materials.

[0040] Reference Figure 3 In this embodiment of the invention, the unloading component 500 is an activated hopper, which is used to connect to the silo. The material first passes through the activated hopper and then enters the screw conveyor 400 through the pipe body 100. The activated hopper has a built-in vibration mechanism, such as a vibration motor or electromagnetic vibrator, which can generate high-frequency, low-amplitude vibrations. The energy is transferred to the hopper wall or the activation plate, breaking down the internal friction and cohesion of the material, preventing the material from clumping and blocking. At the same time, the vibration loosens the material, and together with the inner wall of the hopper, guides the material to flow into the pipe body 100 to achieve uniform and stable unloading.
