[0023] In the adhesive coating industry, during the adhesive supply process, components with solid particles such as color paste, colorant, flame retardant powder, and conductive powder are added to the liquid adhesive. Over time, these solid particles gradually settle out of the liquid adhesive, causing problems such as uneven coating, pipe blockage, and abnormal adhesive formulation performance. This results in poor product appearance, abnormal performance, wasted cleaning time, increased costs, and decreased yield.

[0024] The feeding system of this utility model embodiment includes a feeding bucket, a first pipe, a discharging component and a second pipe. The discharging component includes a discharging trough and a first stirring paddle. By setting the first stirring paddle in the receiving cavity of the discharging trough, the first stirring paddle can stir the glue material in the receiving cavity, which is beneficial to improving the uniformity of the glue material in the discharging trough and reducing the possibility of sedimentation of solid particles in the glue material.

[0025] To facilitate the reader's understanding of the inventive concept of this utility model, the specific structure of the feeding system is described below:

[0026] Please see Figure 1 The feeding system 100 includes a feeding assembly 1, a first pipe 3, a discharging assembly 2, and a second pipe 4. The feeding assembly 1 includes a feeding hopper 11, which has a receiving cavity 11a, a first inlet 11b, and a first outlet 11c. The first inlet 11b and the first outlet 11c are respectively connected to the receiving cavity 11a. One end of the first pipe 3 is connected to the first outlet 11c. The discharging assembly 2 includes a discharging trough 21 and a first stirring paddle 22. The discharging trough 21 has a receiving cavity 21a, a second inlet 21b, and a second outlet 21c. The second inlet 21b and the second outlet 21c are respectively connected to the receiving cavity 21a. The second inlet 21b is connected to the other end of the first pipe 3. The first stirring paddle 22 is disposed in the receiving cavity 21a and is used to stir the material in the receiving cavity 21a. One end of the second pipe 4 is connected to the second outlet 21c, and the other end of the second pipe 4 is connected to the first inlet 11b. The feeding hopper 11 is used to store adhesive material. The adhesive material in the feeding hopper 11 can be conveyed to the discharge chute 21 of the discharge assembly 2 through the first pipe 3. The discharge chute 21 is used to discharge the adhesive material. Excess adhesive material in the discharge chute 21 can be returned to the feeding hopper 11 through the second pipe 4 (e.g., Figure 1 (As indicated by the arrow). This application provides a first stirring paddle 22 in the receiving cavity 21a of the discharge tank 21. The first stirring paddle 22 can stir the adhesive material in the receiving cavity 21a, which helps to improve the uniformity of the adhesive material in the discharge tank 21, reduces the possibility of solid particles settling in the adhesive material, and thus helps to improve coating uniformity and product quality. At the same time, it helps to reduce the possibility of the adhesive material solidifying due to lack of flow, which in turn helps to extend the survival time of the adhesive material. The extended survival time of the adhesive material also helps to improve work efficiency and reduce production costs.

[0027] In some embodiments, the first pipe 3 and the second pipe 4 can be Teflon stainless steel flexible hoses. The first discharge port 11c can use a pump to draw material from the feeding tank 11 to the discharge trough 21.

[0028] In some embodiments, the discharge trough 21 includes a connected side plate 211 and a bottom plate 212, which together enclose a receiving cavity 21a. The discharge trough 21 also includes an overflow plate 213 disposed within the receiving cavity 21a, which divides the receiving cavity 21a into a first cavity 21a1 and a second cavity 21a2. The side plate 211 is provided with a second inlet 21b, which communicates with the first cavity 21a1. The bottom plate 212 is provided with a second outlet 21c, which communicates with the second cavity 21a2. In the direction from the bottom plate 212 to the side plate 211 (first direction X), the side plate 211 extends beyond the overflow plate 213, and the distance between the second inlet 21b and the bottom plate 212 is greater than the length of the overflow plate 213. By setting the side plate 211 to extend beyond the overflow plate 213, i.e., the height of the overflow plate 213 is lower than the height of the side plate 211, the material in the first chamber 21a1 can first overflow into the second chamber 21a2, and then flow back to the feeding hopper 11 through the second discharge port 21c (e.g., Figure 1 (As indicated by the arrow). By setting the distance between the second inlet 21b and the bottom plate 212 to be greater than the length of the overflow plate 213, that is, the height of the second inlet 21b is higher than the height of the overflow plate 213, it is beneficial to reduce the possibility of material overflowing from the first cavity 21a1 to the second inlet 21b.

[0029] In some embodiments, please refer to Figure 1 and Figure 2 The discharge assembly 2 also includes a first motor 23 located outside the receiving cavity 21a. The bottom of the discharge trough 21 has a first opening 2121 communicating with the receiving cavity 21a. The first stirring paddle 22 includes a first rotating shaft 221 and a first blade 222 located inside the receiving cavity 21a. One end of the first rotating shaft 221 is connected to the first motor 23, and the other end passes through the first opening 2121 and is connected to the first blade 222. The first blade 222 is used to stir the material inside the receiving cavity 21a. The first motor 23 drives the first rotating shaft 221 to rotate, thereby driving the first blade 222 to rotate. In some embodiments, the rotation speed and height of the first stirring paddle 22 are adjustable, and the height of the first blade 222 can be lower than the material surface of the discharge trough 21 (e.g., ...). Figure 1 (As shown by the dashed line). In some embodiments, when viewed from the bottom plate 212 toward the side plate 211, the first stirring paddle 22 may be located at the center of the first cavity 21a1.

[0030] In some embodiments, the discharge assembly 2 further includes a first seal 24 disposed between the first opening 2121 and the first rotating shaft 221. The first seal 24 is used to seal the gap between the first opening 2121 and the first rotating shaft 221, which helps to reduce the possibility of material in the discharge trough 21 leaking out of the discharge trough 21 through the first opening 2121. The first seal 24 can be an O-ring.

[0031] In some embodiments, the discharge assembly 2 further includes a coating roller 25, a portion of which is located in the first cavity 21a1. The coating roller 25 is used to coat the material in the first cavity 21a1 onto the product. In the direction from the base plate 212 to the side plate 211, the distance between the coating roller 25 and the base plate 212 is less than the length of the overflow plate 213, which facilitates contact between the coating roller 25 and the material in the first cavity 21a1. In some embodiments, in the direction from the base plate 212 to the side plate 211, the height of the coating roller 25 is higher than the height of the first blade 222, which helps to reduce the possibility of contact between the coating roller 25 and the first blade 222.

[0032] In some embodiments, the feeding hopper 11 includes a hopper body 112 and a hopper lid 111 covering the hopper body 112. The hopper body 112 and the hopper lid 111 together form a receiving cavity 11a, which facilitates the installation, disassembly, and cleaning of the feeding hopper 11. The side wall of the hopper body 112 is provided with a first inlet 11b and a first outlet 11c. In some embodiments, the hopper body 112 is made of stainless steel, and the hopper lid 111 is also made of stainless steel.

[0033] In some embodiments, the feeding assembly 1 further includes a second stirring paddle 12 disposed in the receiving cavity 11a. The second stirring paddle 12 is used to stir the material in the receiving cavity 11a, which helps to improve the uniformity of the adhesive material in the feeding bucket 11, reduces the possibility of sedimentation of solid particles in the adhesive material, and thus helps to improve coating uniformity and product quality. It also helps to reduce the possibility of the adhesive material solidifying due to lack of flow, thereby extending the shelf life of the adhesive material. In some embodiments, when viewed from the top to the bottom of the feeding bucket 11, the second stirring paddle 12 is offset from the center of the feeding bucket 11. This allows the adhesive material to form a reciprocating vortex motion during stirring, preventing the adhesive material from forming a skin or gel at the edges. In some embodiments, the rotation speed and position of the second stirring paddle 12 are adjustable, and the height of the second paddle 122 can be lower than the material surface in the feeding bucket 11 (e.g., ...). Figure 1 (As shown by the dashed line).

[0034] In some embodiments, please refer to Figure 1 and Figure 3The feeding assembly 1 also includes a second motor 13 located outside the receiving cavity 11a. The top of the feeding hopper 11 has a second opening 1111 communicating with the receiving cavity 11a. The second stirring paddle 12 includes a second rotating shaft 121 and a second blade 122 located inside the receiving cavity 11a. One end of the second rotating shaft 121 is connected to the second motor 13, and the other end of the second rotating shaft 121 passes through the second opening 1111 and is connected to the second blade 122. The second blade 122 is used to stir the material inside the receiving cavity 11a. The second motor 13 drives the second rotating shaft 121 to rotate, thereby driving the second blade 122 to rotate. In some embodiments, the second opening 1111 is located on the hopper lid 111.

[0035] In some embodiments, the feeding assembly 1 further includes a second seal 14 disposed between the second opening 1111 and the second rotating shaft 121. The second seal 14 is used to seal the gap between the second opening 1111 and the second rotating shaft 121, which helps to reduce the possibility of material in the feeding hopper 11 leaking out of the feeding hopper 11 through the second opening 1111. The second seal 14 can be an O-ring.

[0036] In some embodiments, the feeding assembly 1 further includes a pulley 15 disposed at the bottom of the feeding hopper 11. In some embodiments, the pulley 15 is disposed at the bottom of the hopper body 112. The pulley 15 can be a steerable lockable pulley 15. When the pulley 15 is unlocked, the feeding hopper 11 can move in different directions via the pulley 15. When the pulley 15 is locked, the feeding hopper 11 can remain stationary. The pulley 15 facilitates the movement of the feeding hopper 11. The number of pulleys 15 can be two or more. In some embodiments, the pulley 15 includes a fixing frame, a roller, and a locking member. One end of the fixing frame is fixed to the bottom of the hopper body 112, the pulley 15 is rotatably disposed at the other end of the fixing frame, and the locking member is movably disposed on the fixing frame. The locking member can switch back and forth between a first position and a second position relative to the fixing member. When the locking member is in the first position relative to the fixing frame, the locking member locks the roller, making it difficult for the roller to roll. When the locking member is in the second position relative to the fixing frame, the locking member unlocks the roller, allowing the roller to roll.

[0037] In some embodiments, the feeding assembly 1 further includes an electrostatic clamp 16 disposed on the feeding hopper 11. The electrostatic clamp 16 is electrically connected to the ground and is used to transfer static electricity from the feeding hopper 11 to the ground, which helps to reduce the possibility of safety accidents such as fires and explosions caused by electrostatic discharge of the feeding hopper 11. In some embodiments, the electrostatic clamp 16 is disposed on the outer surface of the hopper body 112. In some embodiments, the electrostatic clamp 16 includes a clamp 161 and a wire 162. The clamp 161 is disposed on the outer surface of the hopper body 112, one end of the wire 162 is connected to the clamp 161, and the other end of the wire 162 is connected to the ground. The clamp 161 and the wire 162 can be made of metal.

[0038] In some embodiments, the discharge trough 21, the feeding bucket 11, the first stirring paddle 22 and the second stirring paddle 12 may be made of stainless steel, which has good corrosion resistance and is easy to clean.

[0039] In this embodiment of the utility model, the feeding system 100 includes a feeding component 1, a first pipe 3, a discharging component 2, and a second pipe 4. The feeding component 1 includes a feeding bucket 11, and the discharging component 2 includes a discharging trough 21 and a first stirring paddle 22.
