Description

Technical Field

[0001] This utility model relates to the field of logistics, specifically to a roller mounting mechanism and roller device for a sorting system. Background Technology

[0002] Express sorting systems in the logistics industry can quickly classify packages based on express information, greatly improving sorting efficiency and accuracy, and bringing great convenience to people's lives.

[0003] Existing sorting systems consist of multiple sorting carts, each containing two drive wheel assemblies and two guide wheel assemblies. The existing drive wheel assemblies are composed of metal mounting bases, rollers, screws, nuts, washers, etc. Except for the rollers, all other parts are metal, resulting in significant weight and increased system energy consumption. Furthermore, the metal mounting bases are prone to rusting over long-term use, requiring regular maintenance and increasing maintenance costs. In addition, the processing technology for metal parts is relatively complex, leading to higher production costs. With the rapid development of the logistics industry, the performance requirements for sorting systems are becoming increasingly demanding, necessitating not only improved sorting efficiency but also reduced energy consumption and costs. Therefore, developing a novel roller device to replace the existing metal drive wheel assemblies is of significant practical importance. Utility Model Content

[0004] The purpose of this utility model is to provide a roller mounting mechanism and roller device for a sorting system.

[0005] To solve the above-mentioned technical problems, this utility model provides a roller mounting mechanism, including a mounting base and a connecting unit. The connecting unit is embedded in the mounting base and is elastically connected to the mounting base. The roller body is fixed on the mounting base through the shaft hole. The mounting base includes at least a first side plate, a second side plate, and a connecting bridge connecting the first side plate and the second side plate. Both the first side plate and the second side plate include a receiving portion for accommodating the connecting unit.

[0006] Preferably, the connecting unit includes a connecting shaft, which passes through the shaft hole to fix the roller body to the mounting base.

[0007] Preferably, the number of connecting shafts is one or two.

[0008] Preferably, the connecting shaft includes a head, a middle section, and a tail section, the middle section including one or more middle insertion segments, and the tail section including one or more tail insertion segments.

[0009] Preferably, each of the two adjacent middle insertion segments has a middle notch, and each of the two adjacent tail insertion segments has a tail notch.

[0010] Preferably, the tail insertion section is located at the middle notch, and the middle insertion section is located at the tail notch.

[0011] Preferably, the plurality of central insertion segments are distributed around the circumference of the head, and the plurality of central insertion segments and the central notch form an annulus, the diameter of which is larger than the inner diameter of the shaft hole.

[0012] Preferably, the receiving portion includes a head receiving unit for receiving the head and / or a middle receiving unit for receiving the middle portion.

[0013] Preferably, the connecting shaft has a locking protrusion, and the first side plate and the second side plate have locking through holes. The locking protrusion cooperates with the locking through holes to fix the connecting shaft on the mounting base.

[0014] Preferably, the connecting shaft has a locking through hole, and the first side plate and the second side plate have locking protrusions, which cooperate with the locking through hole to fix the connecting shaft on the mounting base.

[0015] Preferably, both the first side plate and the second side plate further include an elastic tongue. When the connecting unit is pressed into the mounting base, the elastic tongue deforms under force and opens outward. When the connecting unit is fully embedded in the mounting base, the elastic tongue returns to its original position and locks the connecting unit.

[0016] Preferably, a U-shaped groove is formed on the first side plate and the second side plate around the edge of the elastic tongue.

[0017] Preferably, the head is provided with an elastic groove surrounding the locking protrusion, so that the locking protrusion can extend and retract axially. When the connecting unit is pressed into the mounting base, the locking protrusion is deformed by force and retracts inward. When the locking protrusion is embedded in the locking through hole, the locking protrusion recovers and locks with the first side plate and the second side plate.

[0018] Preferably, the first side plate and the second side plate are provided with buckles for locking the connecting unit.

[0019] Preferably, the thickness of the undercut gradually increases from bottom to top, which facilitates the pressing of the connecting shaft and also helps to lock the connecting shaft in place after it has been pressed into place.

[0020] Preferably, the elastic tongue has a guide groove on the side near the roller, and the locking protrusion can slide along the guide groove.

[0021] Preferably, the connecting bridge has a connecting hole for connecting to the conveying equipment.

The mounting base includes at least a first side plate, a second side plate, and a connecting bridge connecting the first side plate and the second side plate. Both the first side plate and the second side plate include a receiving portion for receiving the connecting unit.

[0025] This utility model discloses a roller mounting mechanism and roller device. The connecting unit is elastically connected to the mounting base. When the connecting shaft is pressed into the mounting base, the elastic tongue of the mounting base expands outward under force, or the locking protrusion contracts inward under force. When the connecting unit is fully embedded in the mounting base, the elastic tongue returns to its original position and locks the connecting unit, or the locking protrusion returns to its original position and locks with the side plate, facilitating installation and disassembly. The mounting base consists of a first side plate, a second side plate, and a connecting bridge, providing structural stability. The receiving portion on the side plate can well accommodate the connecting unit. The insertion section design at the middle and tail of the connecting shaft, along with their mutually cooperating structure, ensures that the connecting shaft firmly fixes the roller body. Multiple slots and reinforcing ribs on the mounting base reduce its weight while maintaining its strength. Furthermore, the roller body and roller mounting mechanism are made of thermoplastic engineering plastic, replacing the existing metal-type walking wheel assembly, which greatly reduces the weight of the device and thus reduces system energy consumption. Compared to metal, plastic materials have a simpler processing technology, reducing production costs. Plastic mounting bases are not prone to rust and do not require the regular maintenance that metal mounting bases do, thus reducing maintenance costs. Attached Figure Description

[0042] This embodiment provides a roller device 100, which can be installed on a sorting vehicle.

[0043] Figure 1 This is a cross-sectional view of the roller device in one embodiment of the present invention; Figure 2 This is an exploded view of the roller device in one embodiment of this utility model.

[0044] like Figure 1-2As shown, the roller device 100 mainly consists of a roller body 1 and a roller mounting mechanism 2. The roller body 1 has a shaft hole 11 for connecting to the roller mounting mechanism 2. The roller mounting mechanism 2 includes a mounting base 21 and a connecting unit 22. The end of the connecting unit 22 is embedded in the mounting base 21 and elastically connected to it, fixing the roller body 1 to the mounting base 21 through the shaft hole 11. Specifically, the connecting unit 22 includes two connecting shafts 221. The two connecting shafts 221 pass through the shaft hole 11 and are inserted into each other to fix the roller body 1 to the mounting base 21.

[0045] Figure 3 This is a schematic diagram of the mounting base in one embodiment of the present invention; Figure 4 This is a schematic diagram of the mounting base in another embodiment of the present invention; Figure 5 This is a schematic diagram of the mounting base in another embodiment of the present invention.

[0046] like Figure 3-5 As shown, the mounting base 21 includes at least a first side plate 211, a second side plate 212, and a connecting bridge 213 connecting the first side plate 211 and the second side plate 212. The connecting bridge 213 has a connecting hole 2131 for connecting to a conveying device, facilitating the installation and removal of the roller device 100 on the conveying device. Both the first side plate 211 and the second side plate 212 include a receiving portion for accommodating the end of the connecting unit 22. The receiving portion includes a head receiving unit and a middle receiving unit, respectively accommodating the head 2211 and the middle 2212 of the connecting shaft 221. Both the head receiving unit and the middle receiving unit are grooves, and the width of the groove in the head receiving unit is greater than the width of the groove in the middle receiving unit.

[0047] See Figure 3 and Figure 4 In some embodiments, the first side plate 211 and the second side plate 212 of the mounting base 21 are also provided with elastic tongues 216. When the connecting unit 22 is pressed into the mounting base 21, the elastic tongue 216 deforms under force and opens outward. When the connecting unit 22 is fully embedded in the mounting base 21, the elastic tongue 216 returns to its original position and locks the connecting unit 22.

[0048] Figure 3 and Figure 4 Two different elastic tongue structures 216 are presented respectively. See also Figure 3 In some embodiments, the first side plate 211 and the second side plate 212 are respectively provided with U-shaped annular grooves 2111, thereby forming U-shaped elastic tongues 216 on the first side plate 211 and the second side plate 212. In this embodiment, the U-shaped elastic tongues 216 are provided with locking through holes 2161 to facilitate locking after the connecting shaft 221 is pressed in. At this time, see Figure 6A locking protrusion 2214 can be provided on the connecting shaft 221. After the connecting shaft 221 is pressed in and locked, the locking protrusion 2214 is embedded in the locking through hole 2161. See also Figure 4 In some embodiments, the first side plate 211 and the second side plate 212 are each provided with three parallel grooves, thereby forming easily deformable elastic tongues 216 in the first side plate 211 and the second side plate 212. In this embodiment, the first side plate 211 and the second side plate 212 are also provided with buckles 217. Buckles 217 are used to clamp the connecting unit 22, and their thickness gradually increases from bottom to top, which facilitates both the pressing in of the connecting shaft 221 and the clamping of the connecting shaft 221 after it is pressed into place.

[0049] In some embodiments, the elastic tongue 216 is provided with an elongated groove 2162, and the end near the locking through hole 2161 is chamfered. When the connecting shaft 221 is pressed in, the two elastic tongues 216 on both sides open outward, and the locking protrusion 2214 of the connecting shaft 221 can slide along the elongated groove 2162. After the connecting shaft 221 is pressed into place, the locking protrusion 2214 provided on the connecting shaft is engaged in the locking through hole 2161 on the elastic tongue 216 to prevent the connecting shaft from coming out.

[0050] See Figure 5 In some embodiments, the elastic tongue 216 may not be provided on the first side plate 211 and the second side plate 212. Instead, the connecting unit 22 may be provided with a structure that has the same function as the elastic tongue 216, so that the connecting unit 22 can be pressed into the mounting base 21. See below for details.

[0051] See Figure 9 and Figure 10 The connecting unit 22 includes two connecting shafts 221, which, after passing through the shaft hole 11 and interlocking, fix the roller body 1 onto the mounting base 21. Each connecting shaft 221 includes a head 2211, a middle section 2212, and a tail section 2213. The diameter of the head 2211 is larger than the diameter of the middle section 2212, and the diameter of the middle section 2212 is larger than the diameter of the tail section 2213. The diameter of the middle section 2212 is larger than the inner diameter of the shaft hole 11 and matches the width of the middle receiving unit groove. The diameter of the head 2211 matches the width of the head receiving unit groove.

[0052] Figure 6 yes Figure 3 A schematic diagram of the connecting shaft corresponding to the mounting base in the illustrated embodiment. See also the following for some embodiments. Figure 6 The head 2211 is provided with a circular locking protrusion 2214, which cooperates with the locking through hole 2161 opened on the U-shaped elastic tongue 216 to lock the connecting shaft 221 to the first side plate 211 and the second side plate 212 of the mounting base 21, preventing the connecting shaft 221 from coming out of the mounting base 21.

[0053] Figure 7 yes Figure 4 A schematic diagram of the connecting shaft corresponding to the mounting base in the illustrated embodiment. See also... Figure 7 In some embodiments, the head 2211 may not have a locking protrusion 2214, and the first side plate 211 and the second side plate 212 may be provided with buckles 217 respectively. The buckles 217 can also lock the connecting shaft 221 onto the mounting base 21.

[0054] Figure 8 yes Figure 5 A schematic diagram of the connecting shaft corresponding to the mounting base in the illustrated embodiment. See also... Figure 8 In some embodiments, the head 2211 is further provided with an elastic annular groove 2215 surrounding the locking protrusion 2214, allowing the locking protrusion 2214 to extend and retract axially. When the connecting unit 22 is pressed into the mounting base 21, the locking protrusion 2214 deforms and contracts inward under force; when the locking protrusion 2214 is embedded in the locking through hole 2161 on the first side plate 211 and the second side plate 212, the outer surface of the head 2211 fits against the groove surface of the head receiving unit, the locking protrusion 2214 recovers and locks the connecting shaft 221 with the first side plate 211 and the second side plate 212, preventing the connecting shaft 221 from coming out of the mounting base 21.

[0055] See Figure 6-8 The middle section 2212 includes multiple middle insertion segments 2216, and the tail section 2213 includes multiple tail insertion segments 2217. Each pair of adjacent middle insertion segments 2216 has a middle notch, and each pair of adjacent tail insertion segments 2217 has a tail notch. The tail insertion segments 2217 are located at the middle notches, and the middle insertion segments 2216 are located at the tail notches. The multiple middle insertion segments 2216 are distributed circumferentially along the head 2211, and the multiple middle insertion segments 2216 and the middle notches form a ring, the diameter of which is larger than the inner diameter of the shaft hole 11. In some embodiments, the number of middle insertion segments 2216 and the number of tail insertion segments 2217 are both two, with two middle notches between two middle insertion segments 2216 and two tail notches between two tail insertion segments 2217. The number of the middle connector 2216 and the tail connector 2217 can also be set to other numbers, such as 3 or 4.

[0056] In some embodiments, the roller body 1 and the roller mounting mechanism 2 are made of thermoplastic engineering plastics, such as polyamide (PA), glass fiber reinforced polyamide, or polyurethane (TPU), to improve the durability and corrosion resistance of the roller assembly. In some embodiments, the mounting base 21 is also provided with multiple slots and reinforcing ribs to further reduce the weight of the mounting base 21 itself while improving the structural strength of the mounting base 21.

[0057] Figure 9This is a cross-sectional view of two connecting shafts being inserted in one embodiment of this utility model; Figure 10 This is a cross-sectional view of the two connecting shafts and the roller body assembled in one embodiment of the present invention.

[0058] See Figure 9-10 When assembling the roller assembly 100, firstly, the two connecting shafts 221 are passed through the shaft holes 11 of the roller body 1, and then the tails 2213 and the middle portions 2212 of the two connecting shafts 221 are inserted into each other. Next, the head 2211 and the middle portion 2212 of the connecting unit 22 are pressed into the head receiving unit and the middle receiving unit of the mounting base 21, respectively. During the pressing of the connecting shaft, the locking protrusion 2214 and / or the elastic tongue 216 deform. When the locking protrusion 2214 is embedded in the locking through hole 2161 and / or the buckle 217 clamps the connecting shaft 221, the elastic tongue 216 and / or the locking protrusion 2214 return to their original shape and lock the connecting unit 22, thereby completing the assembly of the roller assembly 100.

[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, variations and improvements made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
