[0026] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0027] like Figures 1 to 3 As shown, this utility model provides an anti-overflow skirt mechanism, which is used to prevent materials from overflowing in a belt conveyor system. The anti-overflow skirt mechanism partially elastically fits against the surface of the conveyor belt to achieve a dynamic seal.

[0028] The spill-proof skirt mechanism includes a fixed base plate 10, a guide groove 11 disposed on the fixed base plate 10, a locking component 20 sliding in the guide groove 11, and a spill-proof skirt 30 attached to the fixed base plate 10. The locking component 20 presses the spill-proof skirt 30 onto the fixed base plate 10. The fixed base plate 10 is used to connect the frame to fix the spill-proof skirt mechanism as a whole.

[0029] The guide groove 11 is a long groove structure, which can be configured as a T-groove, dovetail groove, or other open groove structure with a limiting structure. The locking component 20 slides in the guide groove 11 to adjust the pressing position of the spill skirt 30 and transmit the pressing force to the guide groove 11 to form a pressing lock on the spill skirt 30.

[0030] Preferably, the guide groove 11 and the fixing base plate 10 are integrally formed. That is, a groove-shaped structure is directly formed on the fixing base plate 10 to fix the locking rod 22 in the locking assembly 20. The locking rod 22 includes a head and a rod. The head is embedded in the guide groove 11 and the rod extends out of the opening of the guide groove 11.

[0031] Alternatively, a guide rail 40 is fixed on the fixed base plate 10, and a guide groove 11 is provided on the guide rail 40. The guide rail 40 and the fixed base plate 10 are detachably connected, making assembly convenient and connection easy.

[0032] One side of the spill-proof skirt panel 30 is attached to the fixed base plate 10, and the other side is pressed tightly by the locking assembly 20. The spill-proof skirt panel 30 includes a skirt panel body 31 and an elastic arm 32 protruding from one side of the skirt panel body 31. A curved sealing portion 33 is provided at the end of the skirt panel body 31, and the elastic arm 32 is arc-shaped at its intersection with the skirt panel body 31. The spill-proof skirt panel 30 is clamped and pressed onto the fixed base plate 10 by the locking assembly 20, allowing for quick assembly and disassembly, as well as adjustment of the sealing position of the sealing portion 33 and the elastic arm 32.

[0033] The skirt body 31 is made of rubber material to provide suitable elastic deformation and allow it to fit tightly against the surface of the conveyor belt. The sealing part 33 is curved and protrudes to form an inclined contact area, which can both increase the contact area and stabilize the edge of the conveyor belt.

[0034] The end of the skirt panel body 31 is provided with a curved sealing part 33, which can expand the sealing area. The flexible arm 32 is curved and has a suitable elastic deformation force, and can form a double sealing structure with the sealing part 33, further improving the spill prevention effect.

[0035] like Figures 2 to 5 As shown, the elastic arm 32 is an elastic cantilever structure. The elastic arm 32 includes an arc-shaped curved portion 321, an extension portion 323 inclined from one side of the curved portion 321, and a sealing rib 322 protruding from the convex surface of one side of the extension portion 323. The curved portion 321 and the skirt panel body 31 are curved in directions away from the sealing portion 33, while the sealing rib 322 protrudes towards the sealing portion 33. The curved portion 321 and the extension portion 323 form an approximately S-shaped elastic pressing structure, resulting in good elastic pressing effect, a large pressing span, and an elastic angle between the curved portion 321 and the skirt panel body 31.

[0036] The sealing rib 322 serves as a pressing part that presses against one side of the conveyor belt. Its pressing surface adopts an arc-shaped pressing surface to achieve linear sealing and improve the sealing effect. Furthermore, the elastic arm 32 has a built-in metal spring sheet 34. The metal spring sheet 34 has an elastic thin sheet structure, which can improve the elastic pressing effect of the elastic arm 32 while maintaining a good elastic structure and improving the stability of the seal.

[0037] The main body 31 of the skirt panel is made of rubber, and the sealing rib 322 is made of polyurethane and integrally formed with the extension 323. The sealing rib 322 and the extension 323 are integrated, which improves the wear resistance of the elastic arm 32 and provides good elastic deformation. The polyurethane material portion of the sealing rib 322 extends into the extension 323, with a large cross-sectional area and tight connection. Preferably, the extension 323 covers the back of the sealing rib 322.

[0038] In one embodiment, the sealing portion 33 is inclined from the side of the skirt plate body 31 toward the fixed base plate 10. The sealing portion 33 is an inclined protrusion structure, and the sealing portion 33 is inclined from the end of the fixed base plate 10. An approximately triangular angle space is formed between the skirt plate body 31, the sealing portion 33 and the elastic arm 32.

[0039] Preferably, the end of the sealing part 33 is arc-shaped.

[0040] Furthermore, a reinforcing layer 35 made of polyurethane material is laminated to one side surface of the skirt panel body 31. The reinforcing layer 35 faces the fixed substrate 10 and extends to the sealing portion 33. The reinforcing layer 35 is made of polyurethane material to improve the wear resistance of local areas. Preferably, the reinforcing layer 35 is formed on one side surface of the skirt panel body 31, resulting in a large bonding area and high impact strength.

[0041] Preferably, the thickness of the reinforcing layer 35 is less than or equal to half the thickness of the skirt body 31.

[0042] In one embodiment, the locking assembly 20 includes a pressing member 21, a locking rod 22 connected to the guide groove 11, a locking member 23 connected to the locking rod 22, and a pressing block 24 pressed against the skirt body 31. The pressing member 21 is provided with a through locking hole, the locking rod 22 passes through the locking hole of the pressing member 21 and is connected to the locking member 23, and the locking member 23 may be a nut structure to form a detachable lock, and the locking pressure is adjustable.

[0043] Preferably, the locking member 23 is provided with a rotating handle 231, which protrudes from the side of the locking member 23 to facilitate rotation operation.

[0044] One end of the pressing member 21 abuts against the fixed base plate 10, and the other end of the pressing member 21 is fastened to the clamping block 24. The pressing member 21 has an L-shaped structure, with the clamping end of the pressing member 21 close to the fixed base plate 10, and the locking rod 22 located between the clamping block 24 and the clamping end. As the locking member 23 locks the locking rod 22, the pressing member 21 presses the clamping block 24 onto the skirt body 31.

[0045] The clamping block 24 is fixed in contact with the skirt panel body 31. Preferably, the clamping block 24 and the skirt panel body 31 are engaged and positioned. In one embodiment, the clamping block 24 includes a support portion 242 and clamping portions 241 protruding from both sides of the support portion 242. The support portion 242 and the clamping portions 241 form an approximately T-shaped interlocking structure. The clamping portion 241 has a large pressing area, improving the pressing effect. The support plate has a small area, allowing for flexible adjustment of the pressing direction.

[0046] The pressing component 21 is provided with a pressing groove 211, which includes an arc-shaped bottom and a gradually expanding opening. The end of the support part 242 is arc-shaped and embedded in the pressing groove 211 of the pressing component 21. The support part 242 can be slightly rotated along the opening of the pressing component 21 to adjust the pressing angle.

[0047] The pressing part 241 has multiple protruding teeth 243 on its surface, which abut against the skirt body 31. The protruding teeth 243 are configured as triangular protruding teeth 243, oblique prism protruding teeth 243, or columnar protruding teeth 243. The multiple protruding teeth 243 allow for multi-point insertion into the skirt body 31, achieving a biting pressing action. This not only provides a large biting area but also ensures a high degree of tightness in the biting position, resulting in minimal displacement of the skirt body 31 under vibration.

[0048] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
