Description

Technical Field

[0001] The utility model relates to the technical field related to conveyor belts, and in particular to a straight conveyor belt suitable for heavy loads. Background Art

[0002] Conveyor belt, also known as conveyor belt, is the transmission medium in the transmission belt system.

[0003] The existing conveying system generally includes: a main conveying device and one or more branch conveying devices arranged on one side of the main conveying device. The conveying direction of the branch conveying device is perpendicular to the conveying direction of the main conveying device. When the items conveyed on the main conveying device move to the corresponding entrance of the branch conveying device, the heavy objects on the main conveying device are pushed to the branch conveying device by the pushing device to realize the diversion of the items for conveying or output. The conveyor belt on the main conveying device is generally made of PVC. When conveying light goods, it is easy to push the heavy objects on the main conveying device to the branch conveying device through the pushing device. When conveying heavy objects, the heavy objects rub against the conveyor belt on the main conveying device, which can easily cause damage to the conveyor belt. If the conveyor belt on the main conveying device is made of steel, the cost is high, and the items are easily scratched when being pushed away from the conveyor belt on the main conveying device. Utility Model Content

[0004] In order to overcome the existing technical defects, the purpose of the utility model is to provide a straight conveyor belt suitable for heavy loads to solve at least one of the above technical problems.

[0005] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0006] According to one aspect of the utility model, a straight conveyor belt suitable for heavy loads is designed, comprising: a plurality of module frames made of plastic material and a plurality of connecting shafts, each of the module frames being provided with a plurality of plug-in slots at the left end, a plurality of plug-in blocks at the right end, a plurality of driving slots at the bottom, and through holes penetrating the left and right ends of the module frames respectively. The plurality of module frames are arranged in a ring shape, and the plug-in blocks on one of two adjacent module frames are inserted into the plug-in slots on the other and are spliced ​​into a conveyor belt through a connecting shaft passing through the through holes of the two. A plurality of roller groups are longitudinally spaced apart on the top of the module frames, and the roller groups between two adjacent module frames are staggered. Each of the roller groups comprises a plurality of support blocks, through shafts passing through the plurality of support blocks, and a plurality of rollers arranged in adjacent support blocks and rotatably matched with the through shafts, and the rolling conveying direction of the rollers is perpendicular to the conveying direction of the conveyor belt.

[0007] By adopting the above technical scheme, multiple groups of roller assemblies are arranged on the conveyor belt, and a supporting surface for supporting goods is constructed by the top of the rollers on the multiple roller assemblies. The roller groups between two adjacent module frames are staggered to ensure that the supporting plane has a better supporting effect. The roller assemblies are used to maintain a certain distance between the conveyed goods and the top surface of the conveyor belt to prevent the goods from contacting the top surface of the conveyor belt. When the goods are pushed away along the conveying direction perpendicular to the conveyor belt, the goods are in rolling contact with the rollers to prevent the goods from being scratched by friction with the top surface of the conveyor belt when the goods are pushed away from the conveyor belt, thereby ensuring smooth transportation of the goods. In addition, the conveyor belt adopts multiple roller support structures, which is not only suitable for the transportation of lightweight goods, but also for the transportation and output of heavy goods. It has good practicality and low cost.

[0008] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0009] In some embodiments, the roller is a rubber wheel with a plurality of shock-absorbing holes distributed around its circumference. Thus, when the goods are thrown onto the conveyor belt, the roller can play a shock-absorbing role at one end, reducing the risk of damage. In addition, the rubber wheel generates less noise during the rotation of the conveyor belt, and has a certain noise reduction effect compared to iron wheels and ceramic wheels.

[0010] In some embodiments, the bottom of both ends of the module frame are respectively provided with locking plate insertion holes connected to the through holes, the locking plates are inserted into the locking plate insertion holes, and the side of the insertion end of the locking plate is provided with an anti-dropping protrusion inserted into the through hole. By providing locking plates at both ends of the module frame, the connection shaft can be prevented from being separated from the module frame, and the anti-dropping protrusion provided on the locking plate can prevent the locking plate from being separated from the module frame.

[0011] In some embodiments, anti-drop protrusions are provided on both sides of the insertion end of the locking piece.

[0012] In some embodiments, the top of the anti-dropping protrusion is provided with an inclined surface, which facilitates the insertion of the locking piece into the locking piece insertion hole, thereby improving assembly efficiency.

[0013] In some embodiments, the driving slot passes through the module frame, thereby achieving weight reduction and saving manufacturing materials.

[0014] In some embodiments, each of the module frames is formed by longitudinally splicing at least two first module frames, thereby conveyor belts of different widths can be assembled as needed to meet the use requirements of conveyor belts of different specifications and widths.

[0015] In some embodiments, three support blocks are arranged at intervals, and two rollers are arranged.

[0016] In some embodiments, the lower ends of both sides of the middle support block of the three support blocks are provided with triangular reinforcement blocks connected to the top of the module frame, and the lower ends of the other two support blocks facing the middle support block are also provided with triangular reinforcement blocks connected to the top of the module frame. By providing the reinforcement blocks, the connection strength between the support blocks and the module frame can be increased, which is not easy to break and improves the support performance.
