Description

Technical Field

[0001] This utility model relates to the field of synchronous belt technology, specifically a synchronous belt for a logistics sorting machine. Background Technology

[0002] With the rapid development of the logistics industry, logistics sorting machines, as the core equipment of automated sorting systems, directly affect the turnover speed of the entire logistics chain through their operating efficiency and stability. Synchronous belts, as key transmission components of sorting machines, undertake the dual functions of power transmission and item transport; their performance plays a decisive role in sorting accuracy, equipment lifespan, and maintenance costs.

[0003] In existing technologies, the timing belts commonly used in logistics sorting machines are mostly made of rubber. Although they have a certain degree of elasticity and smooth transmission, they have the following problems in practical applications: First, it has insufficient wear resistance. In scenarios involving sorting heavy objects or high-speed operation, the teeth of the synchronous belt are prone to wear and cracking due to meshing friction. The belt body surface is also worn due to continuous contact with the sorted items, resulting in uneven belt thickness, reduced strength, and low average service life. Frequent shutdowns are required for replacement, which significantly increases maintenance costs. Secondly, the backing has low friction. Traditional rubber backing has a smooth surface and a low coefficient of friction with transmission components such as guide wheels and tensioning mechanisms of sorting machines. Under high load or frequent start-stop, it is prone to slippage and lateral displacement, which can lead to deviation in the position of the conveyed items. In severe cases, it can even cause sorting errors and reduce sorting efficiency.

[0004] Therefore, a logistics sorting machine using synchronous belts is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a synchronous belt for a logistics sorting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A synchronous belt for a logistics sorting machine includes a base belt, and a back belt is provided on the outer side of the base belt, the back belt being fixedly connected to the base belt.

[0007] As a preferred embodiment of this utility model, the shoulder strap is made of segmented colloid and is integrally molded using a mold.

[0008] As a preferred embodiment of this utility model, the two ends of the shoulder strap are provided with ramps.

[0009] As a preferred embodiment of this utility model, the outer side of the shoulder strap is provided with several grooves to increase friction.

[0010] As a preferred embodiment of this utility model, the base strip is a T10 seamless base strip integrally molded from polyurethane material.

[0011] As a preferred embodiment of this utility model, the hardness of the shoulder strap is 55 Shore A hardness.

[0012] As a preferred embodiment of this utility model, the back strap and the bottom strap are bonded together by an adhesive.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The bottom belt of this utility model adopts a T10 seamless structure integrally molded from polyurethane material, which improves wear resistance and tear resistance compared with traditional rubber belts, effectively solving the problem of insufficient wear resistance and extending service life. A back strap is set on the outside of the bottom belt, and a groove is set on the outer side of the back strap to increase the friction coefficient. Combined with the balance of elasticity and support, it can prevent items from slipping and shifting, and solve the problem of inaccurate sorting caused by low back friction. In this utility model, the carrying strap is integrally formed using a segmented colloid mold, which is firmly bonded to the bottom strap to prevent delamination and detachment. Combined with the wear-resistant properties of the bottom strap, the service life of the synchronous belt is increased. The sloping design at both ends of the carrying strap ensures a smooth transition of items, has good cushioning performance, prevents jamming and tipping, ensures continuous sorting, and significantly improves the operating efficiency and stability of the logistics sorting machine.

[0018] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Please see Figure 1-3 This utility model provides a technical solution: For an example, please refer to... Figure 1 , 2 3. A synchronous belt for a logistics sorting machine, including a bottom belt 1, a back belt 2 provided on the outer side of the bottom belt 1, and the back belt 2 being fixedly connected to the bottom belt 1.

[0021] The bottom belt 1 meshes with the drive wheel system of the sorting machine to transmit power, while the back belt 2 directly contacts the sorted items to complete the conveying and sorting actions. The bottom belt 1, as the core transmission component of the synchronous belt, adopts a T10 seamless bottom belt structure integrally molded with polyurethane material.

[0022] Polyurethane materials themselves have excellent wear resistance and tear resistance, and their wear life is increased by 2-3 times compared with traditional rubber materials; The T10 seamless structure ensures that the belt body has no splices when the bottom belt 1 is running at high speed, avoiding the risk of breakage caused by stress concentration at the splice, while ensuring precise meshing with the transmission gear teeth and reducing transmission impact caused by meshing gap.

[0023] When the drive wheel of the sorting machine rotates, the teeth of the bottom belt 1 fully mesh with the tooth grooves of the drive wheel, stably transmitting power to the entire synchronous belt, driving the back belt 2 and the items above it to move synchronously, providing a continuous and stable power foundation for the sorting process.

[0024] Please refer to Figure 1 , 2 3. The shoulder strap 2 is made of segmented colloid and is molded in one piece. The two ends of the shoulder strap 2 are provided with ramps 4, and the outer side of the shoulder strap 2 is provided with several grooves 3 to increase friction.

[0025] The shoulder strap 2, as the structure that directly carries the sorted items, is firmly bonded to the bottom strap 1 with adhesive. Even under high temperatures during continuous operation, the adhesive strength between the two remains strong. Its segmented adhesive design, combined with the mold-integrated molding process, ensures that there are no air bubbles or loose adhesion between the shoulder strap 2 and the bottom strap 1, preventing delamination and detachment under high load conditions.

[0026] The grooves 3 on the outer side of the shoulder strap 2 can significantly increase the contact roughness with the bottom surface of the sorted items, effectively preventing the items from slipping due to inertia during acceleration, deceleration or turning, and ensuring that the items are transported to the designated sorting port along the preset trajectory.

[0027] Meanwhile, the hardness of the strap 2 is set to 55 Shore hardness. This hardness range takes into account both elasticity and abrasion resistance. It can adapt to the bottom contour of different items through slight deformation to increase the contact area, and can also avoid the strap sagging due to being too soft or the items bouncing due to being too hard, thus further improving the stability of the transport.

[0028] Please refer to Figure 1 , 2 3. The bottom strap 1 is a T10 seamless bottom strap integrally molded from polyurethane material. The back strap 2 has a hardness of 55 Shore A. The back strap 2 and the bottom strap 1 are bonded together by adhesive.

[0029] The ramps 4 at both ends of the shoulder strap 2 provide a smooth transition for items to enter and leave the synchronous belt. When items are transferred from the preceding conveyor to the synchronous belt, the ramps 4 can reduce the impact force between the bottom surface of the items and the edge of the shoulder strap 2, and avoid local wear on the ends of the shoulder strap 2 by hard items. As items are about to leave the synchronous belt, ramp 4 guides them smoothly to the subsequent sorting chute, preventing items from getting stuck or tipping over due to edge steps, ensuring a continuous and uninterrupted sorting process, which is especially suitable for high-speed sorting scenarios of small and lightweight items.

[0030] The wear-resistant properties of the polyurethane in the bottom belt 1 and the seamless transmission design of T10 solve the problem of insufficient wear resistance of traditional synchronous belts and extend the service life of the belt body. The groove 3 of the shoulder strap 2 has a friction-enhancing structure and a Shore hardness of 55, which improves the friction of the backing. Combined with the stable adhesion of the segmented adhesive, it avoids inaccurate sorting caused by slippage and displacement. The transition buffer design of ramp 4 further ensures the continuity of goods transportation.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
