Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a belt for a residual film recycling machine. Background Technology

[0002] Residual plastic film recycling machines are essential equipment for cleaning and recycling residual plastic film in farmland and are widely used in modern agricultural production. With increasing awareness of farmland protection and increasingly stringent environmental regulations, the demand for residual plastic film recycling machines has increased significantly. To improve the efficiency of residual plastic film recycling, various types of machines have emerged, becoming an important part of modern agricultural machinery. The toothed belt, as one of the core components of the residual plastic film recycling machine, directly affects the machine's working efficiency and reliability.

[0003] Existing residual film recycling machines can be referenced from Chinese Patent Application No. 202322794876.5. The toothed belt includes a belt body and teeth passing through the belt. The belt typically uses existing belts, including a multi-layered structure with an outer fabric layer, a top rubber layer, and a bottom rubber layer. However, during use, the belt's skeleton material is often drilled through, severely damaging its strength and making it prone to breakage. Utility Model Content

[0004] To improve the strength of the belt, this application provides a belt for a residual film recycling machine.

[0005] The technical solution provided in this application for the belt of the residual film recycling machine is as follows:

[0006] A residual film recycling machine belt includes a belt body and a plurality of spikes penetrating the belt body. The belt body includes an outer fabric layer, a top rubber layer and a bottom rubber layer. A tensile body layer is disposed between the top rubber layer and the bottom rubber layer. The tensile body layer is a rope structure.

[0007] By adopting the above technical solution, the rope structure has high strength and plays the main role in tensile strength in the belt body. After the nail teeth pass through the belt body, the rope structure on both sides of the nail teeth can also improve the tensile strength of the belt body at the nail tooth connection. At the same time, the rope structure also improves the overall tensile strength of the belt body.

[0008] Optionally, the cord structure has at least two layers.

[0009] By adopting the above technical solution, the rope structure on both sides of the nail tooth after it passes through the belt body can be further improved, which can also improve the tensile strength of the belt body at the nail tooth connection point; and improve the overall tensile strength of the belt body.

[0010] Optionally, a buffer adhesive layer may be provided between two adjacent layers of cord structure.

[0011] By adopting the above technical solution, the buffer adhesive layer separates the two adjacent rope structures, making the rope structure less prone to misalignment and improving the overall tensile strength.

[0012] Optionally, the cord structure is located on both sides of the spike teeth.

[0013] By adopting the above technical solution, the cord structure is less likely to affect the perforation of the belt body, and can also reduce costs to a certain extent, while ensuring the overall tensile strength of the belt body.

[0014] Optionally, an auxiliary tensile layer is provided between the top adhesive layer and the bottom adhesive layer, wherein the length of the auxiliary tensile layer is not less than twice the diameter of the nail teeth.

[0015] By adopting the above technical solution, the length of the auxiliary tensile layer can be extended beyond the nail teeth. The length of the auxiliary tensile layer is greater than the diameter of the perforation on the belt body, which can further improve the tensile strength at the perforation on the belt body and reduce the cost to a certain extent.

[0016] Optionally, the auxiliary tensile layer is a fabric layer.

[0017] By adopting the above technical solution, the tensile strength of the perforations on the belt body can be further improved.

[0018] Optionally, the width of the fabric layer is the width from the spike teeth to the outer wall of the belt body.

[0019] By adopting the above technical solution, the tensile strength of the perforation on the belt body can be further improved, while the cracking of the belt body between the nail teeth and the outer wall of the belt body can also be reduced.

[0020] Optionally, the auxiliary tensile layer can be an auxiliary cord layer.

[0021] By adopting the above technical solution, the tensile strength of the perforations on the belt body can be further improved.

[0022] Optionally, the belt body also includes a locking assembly. The belt body has a male end and a female end. The locking assembly includes a male locking buckle fixed to the male end and a female locking buckle fixed to the female end. The male locking buckle and the female locking buckle are detachably and fixedly connected.

[0023] By adopting the above technical solution, when the belt body is damaged, the connection between the sub-lock and the female lock can be opened, making it convenient to replace the belt.

[0024] Optionally, the male and female locking buckles are respectively fixedly connected to the rope structure.

[0025] By adopting the above technical solution, the force generated by the sub-lock and the female lock can be transmitted more directly to the rope structure, which improves the connection strength between the sub-lock and the female lock and the main body, and also improves the overall tensile strength of the belt body.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The rope structure improves the tensile strength of the belt body at the tooth connection; at the same time, the rope structure also improves the overall tensile strength of the belt body.

[0028] 2. The tensile strength at the perforations on the belt body can be further improved by the auxiliary tensile layer.

[0029] 3. The belt can be easily replaced via the locking assembly. Attached Figure Description

[0037] The following, together with the appendix, provides a further detailed description of this application.

[0038] Example 1

[0039] refer to Figure 1 and Figure 2This application discloses a belt for a residual film recycling machine, including a belt body and spikes 4. The spikes 4 penetrate the belt body and are arranged equidistantly along the length of the belt body. The belt body includes an outer fabric layer 1, a top rubber layer 2, a tensile layer, and a bottom rubber layer 3. The tensile layer is a rope structure 5, located between the top rubber layer 2 and the bottom rubber layer 3 and arranged along the length of the belt body. The rope structure 5 can be made of high-strength materials such as nylon rope, possessing good tensile strength. After the spikes 4 pass through the belt body, the rope structures 5 on both sides of the spikes 4 can improve the tensile strength of the belt body at the connection point of the spikes 4.

[0040] refer to Figure 3 The cord structure 5 has at least two layers, with a buffer rubber layer 6 between adjacent layers. The buffer rubber layer 6 is made of rubber and has a thickness between 0.5mm and 2mm. Specifically, the function of the buffer rubber layer 6 is to prevent the cord structure 5 from shifting or detaching under external force. It is fixed by vulcanization or adhesive to ensure stability. The cord structure 5 also increases the tensile strength of the belt body at the connection of the spike teeth 4.

[0041] Example 2

[0042] refer to Figure 4 and Figure 5 The difference from Embodiment 1 is that the cord structure 5 is located on both sides of the nail tooth 4, and an auxiliary tensile layer is provided between the top rubber layer 2 and the bottom rubber layer 3. The auxiliary tensile layer is located above or below the cord structure 5, and its length is not less than twice the diameter of the nail tooth 4. It can be symmetrically arranged along the nail tooth 4. The auxiliary tensile layer is a fabric layer 7 or an auxiliary cord layer 8. The width of the fabric layer 7 is the width from the nail tooth 4 to the outer wall of the belt body, and the width of the auxiliary cord layer 8 also covers the distance from the nail tooth 4 to the outer wall of the belt body. The auxiliary tensile layer can further improve the tensile strength at the perforations on the belt body.

[0043] Example 3

[0044] refer to Figure 6 The belt body also includes a locking assembly 9, which includes a sub-locking buckle 91 and a female locking buckle 92. The sub-locking buckle 91 is fixed to the sub-end of the belt body, and the female locking buckle 92 is fixed to the female end of the belt body. The sub-locking buckle 91 and the female locking buckle 92 are respectively fixedly connected to the rope structure 5. The sub-locking buckle 91 and the female locking buckle 92 are detachably fixedly connected and can be connected by a snap-fit, bolt, or pin. The locking assembly 9 facilitates belt replacement.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
