However, with the rise of global environmental awareness, customers continue to push for the removal of plastic from product outer packaging.

[0003] During the processing of the packaging box, the packaging box needs to be placed on the conveyor belt of the conveying system for transportation, so as to transport the product to the next process node in the above-mentioned assembly line for processing. Therefore, the deplasticized packaging box needs to be placed directly on the conveyor belt and in contact with it.

[0004] However, when placing the product directly on the conveyor belt and transporting it, a certain amount of friction will be generated at the contact point between the two, so that the product will directly rub against the surface of the assembly line belt, causing the product appearance to be easily dirty or scratched. At the same time, the conveyor belt is not easy to disassemble and replace after use, which increases the downtime of the equipment. Utility Model Content

[0030] In order to better understand the present invention, Figures 1 to 5 The conveyor belt and conveying system of the embodiments of the present invention are described in detail.

[0031] See also Figure 1 and Figure 2 According to an embodiment of the present invention, a conveyor belt 100 is proposed, comprising a base belt 10 and a buffer belt 20. The base belt 10 is respectively provided with a first connecting portion 11 and a second connecting portion 12 at both ends in its own length direction X; the buffer belt 20 is provided on the surface of the base belt 10, and the buffer belt 20 covers at least a portion of the surface of the base belt 10. The friction force formed on the surface of the buffer belt 20 is less than the friction force formed on the surface of the base belt 10; wherein, the conveyor belt 100 has a first state and a second state. In the first state, the first connecting portion 11 and the second connecting portion 12 on the base belt 10 are separated; in the second state, the base belt 10 is butted end to end through the first connecting portion 11 and the second connecting portion 12 to form a closed ring structure.

[0032] In a conveying system with an assembly line, a conveyor belt 100 is usually used to transport products so that the products can enter the next process node for processing. In the process of using the conveyor belt 100 to transport the products, it is necessary to consider the adverse effects of the conveyor belt 100 on the products, especially after the plastic outer packaging of the products is removed, the products are in direct contact with the conveyor belt 100, which can easily cause direct wear and other damage to the surface of the products, ultimately affecting the appearance of the products.

[0033] Based on the above-mentioned issues, a conveyor belt 100 is proposed in the present application. The conveyor belt 100 is specifically composed of a base belt 10 and a buffer belt 20, that is, the buffer belt 20 is directly connected to the surface of the base belt 10, so that when the conveyor belt 100 is used to transport products, the products are placed on the buffer belt 20 for transportation, avoiding direct contact between the products and the base belt 10.

[0034] Optionally, the base band 10 can be a strip-shaped body made of PVC material, and the buffer band 20 can be a fleece-surface Velcro. The buffer band 20 is covered and connected to the surface of the base band 10. Due to the material properties of the buffer band 20, based on the principle that the different materials used in the buffer band 20 and the base band 10 lead to different corresponding friction forces, the friction force on the surface of the buffer band 20 is smaller than the friction force on the surface of the base band 10. When the product is in direct contact with the buffer band 20, the friction force formed between the two can be reduced, thereby reducing the damage to the product caused by the friction between the two. This application does not specifically limit the specific materials of the base band 10 and the buffer band 20, and it is sufficient to meet the friction requirements of the above-mentioned two.

[0035] Among them, the base belt 10 has a first connecting part 11 and a second connecting part 12 at both ends in the length direction X, so that the conveyor belt 100 as a whole has a first state and a second state. The so-called first state means that the conveyor belt 100 is in a disconnected state, that is, the conveyor belt 100 is not installed on the transmission wheel; the second state means that the first connecting part 11 and the second connecting part 12 at both ends of the conveyor belt 100 are connected end to end, and the whole is put on the transmission wheel to form an annular belt structure, so that it can rotate with the transmission wheel.

[0036] The present application does not impose any special restrictions on the specific structure of the first connection part 11 and the second connection part 12. It is sufficient that the conveyor belt 100 can be stably connected in the second state. At the same time, the two ends of the conveyor belt 100 must be detachably connected to facilitate switching between the first state and the second state.

[0037] An embodiment of the present utility model provides a conveyor belt 100. By arranging a buffer belt 20 on the base belt 10 of the conveyor belt 100, the friction force generated on the buffer belt 20 is smaller than the friction force generated on the base belt 10. Therefore, when the conveyor belt 100 is used to transfer products, the products are directly placed on the buffer belt 20 of the base belt 10. The buffer belt 20 can reduce the wear of the products caused by the friction force, reduce the damage to the products, improve the yield rate of the products, and have better safety protection capabilities for the products. At the same time, the first connecting part 11 and the second connecting part 12 arranged at both ends of the base belt 10 can realize the switching of the conveyor belt 100 between the first state and the second state, that is, it is convenient to complete the flexible disassembly and assembly of the conveyor belt 100, reduce the difficulty of disassembly and assembly of the conveyor belt 100, facilitate the operation of the staff, improve the disassembly and assembly efficiency of the conveyor belt 100, thereby reducing the downtime of the equipment and having higher product transportation efficiency.

[0038] Specifically, in the first state, the conveyor belt 100 is a belt-like structure as a whole, having a first connecting portion 11 and a second connecting portion 12 at its head and tail ends. At this time, the first connecting portion 11 and the second connecting portion 12 are disconnected and do not contact each other; when the conveyor belt 100 needs to be sleeved on the transmission wheel, the staff can connect the first connecting portion 11 and the second connecting portion 12, so that the conveyor belt 100 forms a closed ring-shaped belt structure, so that it can be sleeved on the transmission wheel to complete the rotation transmission, thereby realizing the switching of the conveyor belt 100 from the first state to the second state; when the conveyor belt 100 needs to be disassembled and replaced from the transmission wheel, the staff can directly remove it by disconnecting the first connecting portion 11 and the second connecting portion 12, thereby completing the disassembly process, and realizing the switching of the conveyor belt 100 from the second state to the first state.

[0039] As an alternative embodiment, see Figure 2 The first connecting portion 11 includes a first rack extending along the width direction Y of the base belt 10, and the second connecting portion 12 includes a second rack extending along the width direction Y. In the second state, the first rack and the second rack are meshed and connected.

[0040] Optionally, in this embodiment, the first connecting part 11 and the second connecting part 12 are set as a rack structure, and the detachable connection between the two ends of the conveyor belt 100 is achieved through the engagement between the two racks. For example, a cable structure can be used to quickly complete the disassembly and assembly of the conveyor belt 100.

[0041] An embodiment of the present invention provides a conveyor belt 100. By setting the first connecting part 11 and the second connecting part 12 as a rack structure, the structure is simple and easy to operate. On the basis of using the racks at both ends to complete the meshing connection, it can also be easy to assemble and disassemble, saving the time for assembling and disassembling the conveyor belt 100 and improving the assembly efficiency of the conveyor belt 100.

[0042] As an alternative embodiment, see Figure 2 Each tooth in the first rack and each tooth in the second rack respectively has a connecting hole 13 passing through along the width direction Y. The conveyor belt 100 includes a connecting member 30. In the second state, the connecting holes 13 in the first rack and the connecting holes 13 in the second rack are alternately arranged in the width direction Y, and the connecting member 30 is arranged through the connecting hole 13 along the width direction Y.

[0043] In this embodiment, a connecting hole 13 is provided on each tooth on the basis of setting the first connecting part 11 and the second connecting part 12 as a rack structure. When the first connecting part 11 and the second connecting part 12 are engaged and connected, the teeth at both ends are alternately arranged in the width direction Y, and the connecting holes 13 on each tooth are also correspondingly connected in the width direction Y.

[0044] At this time, in the second state, the connecting member 30 can be directly inserted into a plurality of alternating connecting holes 13 along the width direction Y, thereby further connecting the two ends of the conveyor belt 100, fixing the first connecting part 11 and the second connecting part 12 to prevent the separation of the two.

[0045] Optionally, the connector 30 may be made of a wire structure or a rod-shaped structure, etc. The present application does not impose any special restrictions on the specific material and structure of the connector 30. It is sufficient to ensure that the connector 30 can be smoothly inserted into a plurality of connecting holes 13 arranged along the width direction Y. The connecting holes 13 need to simultaneously meet the requirements of ensuring the smooth passage of the connector 30 and forming a certain constraint on the connector 30 to avoid failure of the connection at both ends due to the falling off of the connector 30.

[0046] An embodiment of the present utility model provides a conveyor belt 100, which is provided with a connecting hole 13 on each tooth of the first rack and the second rack, and then uses a connecting piece 30 to be inserted into the multiple connecting holes 13, so that on the basis of using the rack structure to complete the meshing connection, the connecting piece 30 can also be used to further strengthen the connection between the two, thereby improving the head-to-tail connection strength of the conveyor belt 100, preventing the separation of the meshing structures at both ends caused by excessive local stress, further improving the connection stability of the conveyor belt 100 structure, and having better reliability.

[0047] As an alternative embodiment, see Figure 3 The buffer tape 20 includes a plurality of buffer portions, each of which is disposed on the surface of the base tape 10 and extends along the length direction X, and adjacent buffer portions are spaced apart in the width direction Y of the base tape 10 .

[0048] Optionally, in this embodiment, the buffer belt 20 is divided into a plurality of buffer portions spaced apart from each other, and each buffer portion also extends along the length direction X. This is mainly because in the process of placing the product on the buffer belt 20 for transfer, although the buffer belt 20 can reduce the friction between the two and reduce damage to the product, it is still necessary to reduce the contact area between the product and the buffer belt 20 as much as possible, thereby reducing the wear of the buffer belt 20 itself on the product.

[0049] Therefore, in this embodiment, multiple buffer parts are arranged at intervals. When the product is placed on the buffer belt 20, the middle part of the bottom surface of the product will not contact the buffer belt 20. The buffer part suspends the product, and the middle part is suspended and transferred, thereby reducing the contact area between the bottom of the product and the buffer belt 20, and thus reducing the overall wear effect of the buffer belt 20 on the product.

[0050] Optionally, when multiple buffer parts are used to transfer products, not only is the middle part of the bottom of the product suspended, but the local position of its edge can also be kept suspended to avoid direct contact with the buffer part. Specifically, the position can be adjusted appropriately according to the actual product structure to reduce the contact area between the product and the buffer belt 20.

[0051] As for the number of buffer parts to be set, it can be determined according to the actual product size. For example, when the product is a packaging box, if the size of the packaging box is large, more buffer parts can be set in the width direction Y to ensure the supporting ability of multiple buffer parts to the packaging box and prevent the occurrence of unstable transmission. The number of buffer parts can be adjusted according to the actual product size, in order to ensure the supporting strength of the product and appropriately reduce the contact area with the product.

[0052] An embodiment of the present utility model provides a conveyor belt 100, which arranges a buffer belt 20 into a plurality of buffer parts spaced apart from each other, and utilizes the buffer parts to make direct contact with the product, thereby reducing the contact area with the product through the gaps between the buffer parts. On the basis of utilizing the buffer parts to form a stable support for the product, the wear effect of the buffer belt 20 on the product is also reduced, thereby further improving the protection capability of the product.

[0053] As an alternative embodiment, see Figure 3 The plurality of buffer portions include a first buffer portion 21 and a second buffer portion 22 . The first buffer portion 21 and the second buffer portion 22 extend along the length direction X and are spaced apart and arranged in parallel with each other.

[0054] Optionally, in this embodiment, the buffer portion is set as two structures extending parallel to the length direction X. The first buffer portion 21 and the second buffer portion 22 can better provide certain support for the product, so that the product forms two-point stable support in the width direction Y, while also meeting the size requirements of products such as packaging boxes.

[0055] The gap size between the first buffer portion 21 and the second buffer portion 22 needs to be determined according to the actual size of the product, and the distance between the two is appropriately adjusted to ensure that the first buffer portion 21 and the second buffer portion 22 can simultaneously raise the product.

[0056] An embodiment of the present invention provides a conveyor belt 100, which can ensure the most basic stability of product support by setting the buffer belt 20 as a first buffer part 21 and a second buffer part 22, and using the two buffer parts to form two-point support in the width direction Y. On this basis, it can meet the transportation needs of small-sized products and save the application cost of the buffer belt 20.

[0057] As an optional embodiment, the width of the first buffer portion 21 and the second buffer portion 22 is comprised between 20-25 mm, and the width of the gap between the first buffer portion 21 and the second buffer portion 22 is comprised between 15-20 mm.

[0058] An embodiment of the present invention provides a conveyor belt 100, which meets the transportation needs of most packaging box products by setting the first buffer part 21 and the second buffer part 22 to the above-mentioned size and adjusting the distance between the two within the above-mentioned range, conforms to the transportation stability conditions of the product size, has better product adaptability, and is beneficial to saving material costs.

[0059] As an alternative embodiment, see Figure 4 and Figure 5 The buffer tape 20 includes a plurality of buffer layers, and the plurality of buffer layers are stacked along the thickness direction of the base tape 10 .

[0060] In this embodiment, the buffer belt 20 is configured as a plurality of buffer layers stacked along the thickness direction. This is mainly because a single buffer layer may be damaged during contact with the product, thereby increasing the friction at the contact surface of the product and causing damage to the product. After a single buffer layer contacts the product, the friction is unstable. On this basis, in this embodiment, the buffer belt 20 is configured as a stacked structure of multiple buffer layers.

[0061] Optionally, the overall thickness of the buffer belt 20 can be adjusted according to the set number of buffer layers, so as to form a more stable cushion for the product, so that the friction between the two meets the requirements of safe transportation, further reducing the risk of product damage.

[0062] The present application does not impose any special restrictions on the specific number of buffer layers. When stacking the buffer layers, it is necessary to appropriately thicken the buffer belt 20 as a whole, and at the same time control the overall height. On the basis of utilizing the buffer layer to reduce the friction between the product and the buffer belt 20 as a whole, avoid transportation instability caused by the buffer belt 20 being too thick.

[0063] An embodiment of the present utility model provides a conveyor belt 100. By setting the buffer belt 20 as a structure in which multiple buffer layers are stacked, the size of the buffer belt 20 in the thickness direction can be adjusted, which is convenient for controlling the overall thickness of the buffer belt 20, forming a more stable support and padding for the product. On the basis of reducing the friction between the contact surface between the product and the buffer belt 20, the stability of the contact between the two is further improved, providing reliable guarantee for safe and stable product transportation.

[0064] As an alternative embodiment, see Figure 5 The multiple buffer layers include a first buffer layer 23 and a second buffer layer 24. The first buffer layer 23 is arranged on the base tape 10 and the second buffer layer 24 is arranged on the side of the first buffer layer 23 away from the base tape 10 in the thickness direction. The thickness of the first buffer layer 23 is 1.5-2 mm, and the thickness of the second buffer layer 24 is 2.5-3 mm.

[0065] Optionally, the staff can adjust the thickness of different buffer layers according to the actual product structure to meet the requirements for product heightening, improve the stability of the contact surface, and further isolate the distance between the product and the base tape 10.

[0066] An embodiment of the present utility model provides a conveyor belt 100. By setting the buffer belt 20 to a structure of a first buffer layer 23 and a second buffer layer 24, the thickness of the two buffer layers is controlled within the above-mentioned range, and the stability of the first buffer layer 23 is reinforced by the second buffer layer 24. While having a lower friction between the product and the buffer belt 20, it also ensures the stability of the product during the transmission process, prevents adverse phenomena such as wear or deviation from the conveyor belt 100, and further improves the safe transmission performance of the product.

[0067] As an optional embodiment, the buffer belt 20 is connected to the base belt 10 by sewing.

[0068] Optionally, in this embodiment, the buffer belt 20 is directly sewn to the surface of the base belt 10, thereby reducing the large friction generated on the surface of the base belt 10. The present application does not specifically limit the connection method between the two, as long as a stable connection between the two can be achieved. It can be a fixed connection, such as through an adhesive connection, or a detachable connection, so as to facilitate the adjustment of the buffer belt 20.

[0069] An embodiment of the present utility model provides a conveyor belt 100, which improves the connection stability of the buffer belt 20 on the base belt 10 by sewing the buffer belt 20 to the base belt 10, reduces the risk of the buffer belt 20 falling off on the base belt 10, and minimizes the impact of the connection method on product transportation. It is easy to operate and facilitates process molding and later adjustment.

[0070] According to an embodiment of the present invention, a conveying system is provided, comprising the conveyor belt 100 as described above.

[0071] Optionally, the conveying system is not limited to conveying in the field of packaging boxes. In the assembly lines of various other technical fields, as long as the conveying system uses the conveyor belt 100 to transport products, the conveyor belt 100 provided in this application can be used. This application does not limit this.

[0072] The embodiment of the present utility model provides a conveyor belt and a conveying system. By arranging a buffer belt on the base belt of the conveyor belt, the friction force generated on the buffer belt is smaller than the friction force generated on the base belt. Therefore, when the conveyor belt is used to transfer products, the products are directly placed on the buffer belt of the base belt. The buffer belt can reduce the wear of the products caused by the friction force, reduce the damage to the products, improve the yield rate of the products, and have better safety protection capabilities for the products. At the same time, the first connecting part and the second connecting part arranged at both ends of the base belt can realize the switching of the conveyor belt between the first state and the second state, that is, it is convenient to complete the flexible disassembly and assembly of the conveyor belt, reduce the difficulty of disassembly and assembly of the conveyor belt, facilitate the operation of the staff, improve the disassembly and assembly efficiency of the conveyor belt, thereby reducing the downtime of the equipment and having higher product transportation efficiency.

[0073] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
