[0002] In modern industrial production, conveyor belts are essential equipment widely used for material handling. With the continuous development of industry, the demand for conveyor belts is increasing, and their performance and quality are receiving more and more attention.

[0003] However, existing industrial conveyor belts are structurally indivisible. When the outer surface of the conveyor belt ages, is damaged, or becomes severely contaminated after prolonged use, the entire conveyor belt often has to be replaced, which leads to a significant increase in costs and a serious waste of resources. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an oil- and corrosion-resistant conveyor belt to solve the aforementioned problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an oil-resistant and corrosion-resistant conveyor belt, comprising an inner belt body and positioning belt bodies distributed on its outer side. A replaceable surface belt body is provided on the outer side of the positioning belt body. The replaceable surface belt body adopts a structure that can be separated at both ends. Both ends of the seam of the replaceable surface belt body are set as stepped shapes that can be smoothly connected. The left end edge of the splicing end of the replaceable surface belt body is attached to the upper part of the right end edge. The splicing contact surfaces of the left end edge and the right end edge of the replaceable surface belt body are provided with rigid positioning plates. The top of the rigid positioning plate of the replaceable surface belt body has a plurality of splicing protrusions evenly arranged from left to right. The plurality of splicing protrusions are correspondingly engaged with the interior of a plurality of positioning holes provided inside the rigid positioning plate below the left end edge. A plurality of splicing bolts are screwed onto the top of the left end edge of the replaceable surface belt body. The studs of the plurality of splicing bolts are inserted into the positioning holes and screwed into the center of the splicing protrusions inside.

[0008] As a preferred technical solution of this utility model, the inner surface of the replaceable surface layer belt has a number of positioning protrusions evenly distributed perpendicular to the length direction of the belt, and the number of positioning protrusions are correspondingly engaged with the interior of a number of positioning grooves provided on the outer surface of the positioning belt.

[0009] As a preferred technical solution of this utility model, the overall cross-section of the positioning protrusion is set as a semi-circular shape, and a number of semi-circular annular protrusions that fit the outer surface of the positioning protrusion are evenly arranged from left to right on the outer side of the positioning protrusion. A number of semi-circular annular grooves that fit the semi-circular annular protrusions are evenly arranged inside each positioning groove.

[0010] As a preferred technical solution of this utility model, the top surface of the left end of the replaceable surface layer is uniformly provided with a number of nut grooves for hiding each splicing bolt nut.

[0011] As a preferred technical solution of this utility model, the top surface of the replaceable surface layer tape splicing end is bonded with a covering film that only covers its splicing area.

[0012] As a preferred technical solution of this utility model, the rigid positioning plate is made of PVC material.

[0013] As a preferred technical solution of this utility model, the replaceable surface layer is made of silicone rubber, and the covering film is made of corrosion-resistant and oil-resistant film material.

[0014] Compared with the prior art, this utility model provides an oil- and corrosion-resistant conveyor belt, which has the following beneficial effects:

[0015] The replaceable outer layer of this conveyor belt offers numerous significant benefits. Firstly, when the conveyor belt ages after prolonged use, only the replaceable outer layer needs replacement, eliminating the need to replace the entire belt and minimizing cost and resource waste. Secondly, its ingenious installation structure, through the interplay of positioning protrusions and grooves, and the fitting of semi-circular protrusions and grooves, ensures the replaceable outer layer is securely mounted on the positioning belt, guaranteeing installation stability and preventing displacement during operation, thus ensuring the conveyor belt's operational stability. Furthermore, the replaceable outer layer features a separable structure at both ends, with smoothly connected stepped joints. Combined with rigid positioning plates, splicing protrusions, and splicing bolts, this not only ensures a smooth conveyor belt surface after splicing, reducing resistance and wear during material transport, but also makes replacement extremely convenient. It requires no complex tools or cumbersome procedures, allowing for quick replacement and improving work efficiency. Furthermore, the rigid positioning plate, made of a material with a certain degree of hardness and wear resistance, provides a good positioning structure for the splicing bolts, further enhancing the reliability of the splice joint. In summary, this replaceable structure and special installation method not only extend the service life of the conveyor belt and improve the convenience and efficiency of replacement, but also reduce costs, demonstrating significant practical application value and economic benefits.

[0028] Please see Figure 1-4 An oil- and corrosion-resistant conveyor belt mainly consists of an inner belt body 1, a positioning belt body 2 distributed on its outer side, and a replaceable surface belt body 3 set on the outer side of the positioning belt body 2.

[0029] The inner belt 1 serves as the basic structure of the conveyor belt, playing a major supporting and load-bearing role. The positioning belt 2 is tightly fitted to the outer side of the inner belt 1, and several positioning grooves 21 are provided on its outer belt surface. Each positioning groove 21 has several semi-circular annular grooves 211 evenly arranged inside.

[0030] The inner surface of the replaceable surface layer belt 3 is evenly distributed with several positioning protrusions 4 perpendicular to the length of the belt. The overall cross-section of these positioning protrusions 4 is semi-circular, and several semi-circular annular protrusions 41 that fit against its outer surface are evenly arranged from left to right on its outer side. The positioning protrusions 4 cooperate with the positioning grooves 21 on the outer surface of the positioning belt 2, and the semi-circular annular protrusions 41 and the semi-circular annular grooves 211 inside the positioning grooves 21 are adapted to each other, so that the replaceable surface layer belt 3 can be firmly installed on the positioning belt 2, which can effectively prevent the replaceable surface layer belt 3 from shifting during operation.

[0031] The replaceable surface layer belt 3 is a key component of this conveyor belt. It features a detachable end structure for easy replacement and maintenance. Both ends of the seam of the replaceable surface layer belt 3 are designed with a stepped shape for smooth connection, ensuring a flat surface after splicing and reducing resistance and wear during material transport. The left edge of the spliced ​​end of the replaceable surface layer belt 3 is fitted above the right edge. Rigid positioning plates 31, made of PVC material, are installed on the splicing contact surface, providing a good positioning structure for the passing splicing bolts 32.

[0032] On the top of the rigid positioning plate 31 of the replaceable surface layer belt 3, several splicing protrusions 33 are evenly spaced from left to right. These splicing protrusions 33 are correspondingly engaged with the interior of several positioning holes 35 provided inside the rigid positioning plate 31 on the left end and below, achieving initial positioning and fixation of the splice joint. Simultaneously, several splicing bolts 32 are screwed onto the top of the left end of the replaceable surface layer belt 3. The studs of these bolts 32 are inserted into the positioning holes 35 and screwed into the center of the splicing protrusions 33 inside, further strengthening the connection strength of the splice joint and ensuring that the conveyor belt will not loosen or separate during operation. To make the conveyor belt surface more aesthetically pleasing and neat, several nut grooves 34 are evenly provided on the top surface of the left end of the replaceable surface layer belt 3 at the splice end to conceal the nuts of each splicing bolt 32.

[0033] To further improve the sealing and corrosion resistance of the conveyor belt splices, a cover film 5 is bonded to the top surface of the splice end of the replaceable surface belt 3, covering only the splice area. The replaceable surface belt 3 is made of silicone rubber, which has excellent oil and corrosion resistance, effectively extending the service life of the conveyor belt. The cover film 5 is made of a corrosion- and oil-resistant material, effectively preventing oil and corrosive substances from penetrating the splice, thus ensuring the overall performance and reliability of the conveyor belt.
