Description

Technical Field

[0001] This utility model relates to the technical field of logistics transportation, and more specifically, to a belt conveyor equipment. Background Technology

[0002] In the express delivery and logistics industry, logistics conveying devices are required for the transportation of goods. Most commonly used logistics conveying devices consist of a geared motor that drives the drum to rotate through transmission components such as sprockets, chains, or synchronous pulleys and synchronous belts, thereby driving the belt to move and achieve the purpose of transporting goods.

[0003] In existing logistics conveyor systems, rollers are mostly installed and removed through notches on the machine body. However, due to the compact arrangement of multiple logistics conveyor systems in some express delivery workshops, or the limited space for the logistics conveyor systems, it is difficult to install, remove, or replace rollers through the notches, which is detrimental to improving the efficiency of installation, removal, and maintenance of logistics conveyor systems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing logistics conveying devices, which are difficult to assemble and disassemble, and to provide a belt conveyor that is easy to use, can improve the assembly and disassembly efficiency of belt conveyor, and can improve maintenance efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A belt conveyor is provided, comprising a frame, a first driven roller assembly mounted on the frame, a mounting plate connected to the frame, and a second driven roller assembly and a drive roller detachably connected to the mounting plate; it also includes a conveyor belt, which is drively connected to the first driven roller assembly, the second driven roller assembly, and the drive roller; wherein the mounting plate has a mounting position, the mounting position including a first mounting hole and a snap-fit ​​hole communicating with the first mounting hole, the drive roller being mounted in the snap-fit ​​hole, and the cross-sectional area of ​​the first mounting hole being larger than the cross-sectional area of ​​the drive roller.

[0007] This utility model relates to a belt conveyor device. A drive roller, a first driven roller assembly, and a second driven roller assembly can drive a conveyor belt for transport. The mounting position on the mounting plate allows for the installation and removal of the drive roller. The cross-sectional area of ​​the first mounting hole is larger than that of the drive roller, allowing the drive roller to be installed and removed by insertion or withdrawal through the first mounting hole. This improves the installation and disassembly efficiency of the belt conveyor device and enhances maintenance efficiency. The snap-fit ​​hole improves the installation stability of the drive roller, thereby improving the operational stability of the belt conveyor device.

[0008] Preferably, the cross-sectional area of ​​the snap-fit ​​hole is smaller than the cross-sectional area of ​​the drive roller; the snap-fit ​​hole includes a receiving portion and a recessed snap-fit ​​portion communicating with the first mounting hole, and the drive roller is mounted on the recessed snap-fit ​​portion. The receiving portion improves the ease of mounting and dismounting the drive roller, and the recessed snap-fit ​​portion improves the snap-fit ​​stability of the drive roller.

[0009] Preferably, the first mounting hole is connected to the edge of the mounting plate. This connection allows the drive roller to be quickly installed and removed via this connection.

[0010] Preferably, a sealing plate assembly is detachably connected to the outer side of the mounting plate, and the sealing plate assembly is located at a position corresponding to the mounting position. The sealing plate assembly reduces the occurrence of unnecessary accidental collisions and lowers the failure rate of the belt conveyor.

The second driven roller is mounted on the mounting plate, the fixed end of the second tensioning mechanism is connected to the mounting plate, and the tensioning end of the second tensioning mechanism is connected to the tensioning roller. Both the second driven roller and the tensioning roller press against the outer ring surface of the conveyor belt. The arrangement of the second driven roller, the tensioning roller, and the second tensioning mechanism can improve the adjustability and transmission stability of the belt conveyor.

[0012] Preferably, the mounting plate has a second mounting hole and a first sliding hole communicating with the second mounting hole. The tensioning roller is mounted in the first sliding hole, and the cross-sectional area of ​​the second mounting hole is larger than the cross-sectional area of ​​the tensioning roller. This design, where the cross-sectional area of ​​the second mounting hole is larger than that of the tensioning roller, allows the tensioning roller to be installed and removed by inserting or withdrawing it at the second mounting hole.

[0013] Preferably, the second tensioning mechanism includes a second connecting plate connected to the outer side of the mounting plate and a second adjusting screw connected to the second connecting plate. The tensioning roller is slidably connected to the second adjusting screw, and a locking nut for positioning the tensioning roller is also connected to the second adjusting screw.

[0014] Preferably, a first tensioning mechanism is provided between the machine body and the first driven roller assembly, and the first tensioning mechanism is installed on the inner side of the machine body. Installing the first tensioning mechanism on the inner side of the machine body can reduce unnecessary accidental collisions and lower the failure rate of the belt conveyor.

[0015] Preferably, the first tensioning mechanism includes a first connecting plate connected to the inner side of the machine body and a first adjusting screw threadedly connected to the first connecting plate.

[0032] Example 1

[0033] like Figures 1 to 5The first embodiment of the belt conveyor of this utility model is shown, including a machine body 100, a first driven roller group 200 mounted on the machine body 100, and a mounting plate 300 connected to the machine body 100. The mounting plate 300 is detachably connected to a second driven roller group and a drive roller 400. It also includes a conveyor belt 500, which is drivenly connected to the first driven roller group 200, the second driven roller group, and the drive roller 400. The mounting plate 300 is provided with a mounting position, which includes a first mounting hole 310 and a snap-fit ​​hole 320 communicating with the first mounting hole 310. The drive roller 400 is mounted in the snap-fit ​​hole 320. The cross-sectional area of ​​the first mounting hole 310 is larger than the cross-sectional area of ​​the drive roller 400.

[0034] The drive roller 400, the first driven roller group 200, and the second driven roller group can drive the conveyor belt 500 for conveying. The mounting position provided at the mounting plate 300 can be used for the installation and removal of the drive roller 400. The cross-sectional area of ​​the first mounting hole 310 is larger than that of the drive roller 400, so that the drive roller 400 can be installed and removed by inserting or pulling it out at the first mounting hole 310, which can improve the installation and removal efficiency of the belt conveyor and improve maintenance efficiency. The snap-fit ​​hole 320 can improve the installation stability of the drive roller, thereby improving the operational stability of the belt conveyor.

[0035] like Figure 1 and Figure 2 As shown, the machine body 100 includes two side plates. A first driven roller assembly 200 is located between the two side plates, i.e., the first driven roller assembly 200 is located on the inner side of the side plates. Mounting plates 300 are connected to the outer sides of both side plates. A drive roller 400 is located directly below the machine body 100. A second driven roller assembly is located between the drive roller 400 and the first driven roller assembly 200, and the second driven roller assembly is located near the lower end of the machine body 100. Both the drive roller 400 and the second driven roller assembly are located between the two mounting plates 300, i.e., both are located on the inner side of the mounting plates 300. It should be noted that locking components can also be installed at the roller shaft of the drive roller 400 to improve its installation stability. In this embodiment, the drive roller 400 is an electric roller with both the motor and reducer built into the cylinder. The electric roller can improve the transmission efficiency and assembly / disassembly efficiency of the belt conveyor.

[0036] like Figure 3 and Figure 4As shown, the cross-sectional area of ​​the snap-fit ​​hole 320 is smaller than that of the drive roller 400. The snap-fit ​​hole 320 includes a receiving portion 321 communicating with the first mounting hole 310 and a recessed snap-fit ​​portion 322, and the drive roller 400 is mounted on the recessed snap-fit ​​portion 322. The receiving portion 321 improves the ease of mounting and dismounting the drive roller 400, the recessed snap-fit ​​portion 322 improves the snap-fit ​​stability of the drive roller, and the smaller cross-sectional area of ​​the snap-fit ​​hole 320 compared to the cross-sectional area of ​​the drive roller 400 also improves the snap-fit ​​stability of the drive roller. In this embodiment, the recessed snap-fit ​​portion 322 is located below the receiving portion 321, and the recessed snap-fit ​​portion 322 is a downwardly concave arc shape, while the receiving portion 321 is an outwardly concave arc shape. The first mounting hole 310 and the receiving portion 321 are also connected by a connecting portion 323, which is strip-shaped.

[0037] like Figure 1 As shown, a sealing plate assembly 330 is detachably connected to the outer side of the mounting plate 300, and the sealing plate assembly 330 is located at a position corresponding to the mounting position. The sealing plate assembly 330 reduces the occurrence of unnecessary accidental collisions and lowers the failure rate of the belt conveyor. In this embodiment, the sealing plate assembly 330 can be connected to the mounting plate 300 by bolts. The locking member for the drive roller 400 can also be fixed to the roller shaft of the drive roller 400 via the sealing plate assembly 330. The sealing plate assembly 330 includes a first sealing plate and a second sealing plate corresponding to the first mounting hole 310 and the snap-fit ​​hole 320 respectively, and can be used for covering. It should be noted that the first sealing plate and the second sealing plate can be separate plates or integrally formed.

[0038] like Figures 1 to 3 , Figure 5 As shown, the second driven roller assembly includes a second driven roller 600, a tensioning roller 710, and a second tensioning mechanism 720. The second driven roller 600 and the tensioning roller 710 are located on the same horizontal plane, and the second driven roller 600 is connected to the mounting plate 300. Both the second driven roller 600 and the tensioning roller 710 press against the outer ring surface of the conveyor belt 500. The second tensioning mechanism 720 is located outside the mounting plate 300, with its fixed end connected to the mounting plate 300 and its tensioning end connected to the tensioning roller 710. The second driven roller 600 improves the transmission stability of the belt conveyor, while the tensioning roller 710 and the second tensioning mechanism 720 improve the adjustability and transmission stability of the belt conveyor.

[0039] Among them, such as Figure 3 and Figure 4As shown, the mounting plate 300 has a second mounting hole 340 and a first sliding hole 350 communicating with the second mounting hole 340. The tensioning roller 710 is mounted in the first sliding hole 350. The cross-sectional area of ​​the second mounting hole 340 is larger than the cross-sectional area of ​​the tensioning roller 710. This larger cross-sectional area allows the tensioning roller 710 to be installed and removed from the second mounting hole 340 by insertion or withdrawal. In this embodiment, the first sliding hole 350 extends horizontally from one end near the second driven roller 600.

[0040] like Figure 5 As shown, the second tensioning mechanism 720 includes a second connecting plate 721 connected to the outer side of the mounting plate 300 and a second adjusting screw 722 fixedly connected to the second connecting plate 721. The second adjusting screw 722 is horizontally arranged, and the tensioning roller 710 is slidably connected to the second adjusting screw 722. A locking nut 723 for positioning the tensioning roller 710 is also connected to the second adjusting screw 722. In this embodiment, the second connecting plate 721 is provided with a second sliding hole 724 adapted to the first sliding hole 350. A slide cylinder 711 is connected to the end of the roller of the tensioning roller 710. The slide cylinder 711 passes through the second sliding hole 724 and is slidably sleeved on the second adjusting screw 722. When the slide cylinder 711 slides on the second adjusting screw 722, it can drive the tensioning roller 710 to slide as well. After the position adjustment is completed, the locking nut 723 can be used to abut against the slide cylinder 711 to achieve positioning. In this embodiment, the second adjusting screw 722 may be equipped with one or two locking nuts 723. When it is equipped with two locking nuts 723, they can be positioned at both ends of the slide cylinder 711 respectively.

[0041] The working principle of a belt conveyor device in this embodiment is as follows:

[0042] The rotation of the drive roller 400 drives the conveyor belt 500, the second driven roller 600, the tension roller 710, and the first driven roller group 200 to move, allowing goods to be transported on the conveyor belt 500. When tension adjustment is required, it can be done through the second tensioning mechanism 720. When the drive roller 400 needs to be replaced or repaired, the sealing plate assembly 330 can be removed first, and then the drive roller 400 can be moved along the connecting part 323 to the first mounting hole 310 and pulled out. The new drive roller 400 will be inserted through the first mounting hole 310, and the roller of the drive roller 400 will be moved along the connecting part 323 to the receiving part 321 and engaged with the recessed engaging part 322 to complete the installation. When the tension roller 710 needs to be replaced or repaired, the tension roller 710 can be moved to the second mounting hole 340 and pulled out. The new tension roller 710 will be inserted through the second mounting hole 340 and moved to the first sliding hole 350 for installation.

[0043] Example 2

[0044] This embodiment is a second embodiment of a belt conveyor device. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 6 As shown, the first mounting hole 310 is connected to the edge of the mounting plate 300. This connection allows the drive roller 400 to be quickly installed and removed through this connection, making the belt conveyor suitable for different installation conditions.

[0045] Example 3

[0046] This embodiment is a third embodiment of a belt conveyor device. This embodiment is similar to Embodiment 1 or 2, except that, as shown in the following... Figures 1 to 3 , Figure 7 and Figure 8 As shown, a first tensioning mechanism 800 is provided between the machine body 100 and the first driven roller assembly 200, and the first tensioning mechanism 800 is installed on the inner side of the machine body 100. The arrangement of the first tensioning mechanism 800 on the inner side of the machine body 100 can reduce the occurrence of unnecessary accidental collisions and reduce the failure rate of the belt conveyor equipment.

[0047] Figures 1 to 3 ,like Figure 7As shown, the first tensioning mechanism 800 includes a first connecting plate 810 connected to the inner side of the machine body 100 and a first adjusting screw 820 threadedly connected to the first connecting plate 810. The abutting end of the first adjusting screw 820 abuts against the first driven roller assembly 200. The first connecting plate 810 is provided with a first adjusting hole 811, and the machine body 100 is provided with a second adjusting hole 110 at the position corresponding to the first adjusting hole 811. The adjusting end of the first adjusting screw 820 protrudes from the second adjusting hole 110. The first adjusting hole 811 allows for easy adjustment of the first driven roller assembly 200 from the outside of the machine body 100 via the first adjusting screw 820, thereby adjusting the tension of the conveyor belt 500.

[0048] In this embodiment, a connecting nut 821 is fixed on the first connecting plate 810, and the first adjusting screw 820 is connected to the first connecting plate 810 through the connecting nut 821. Both ends of the machine body side plate are provided with a first L-shaped groove 120, and the first L-shaped groove 120 communicates with the edge of the machine body side plate; a second L-shaped groove 812 is provided on the first connecting plate 810 at a position corresponding to the first L-shaped groove 120, and the second L-shaped groove 812 communicates with the edge of the first connecting plate 810. The first L-shaped groove 120 and the second L-shaped groove 812 are provided to allow the first driven roller assembly 200 to adjust its position along the groove, and the communication with the edge facilitates the maintenance and replacement of the first driven roller assembly 200. In this embodiment, the first connecting plate 810 is also provided with multiple connecting holes 813, through which the first connecting plate 810 can be connected to the machine body side plate. Specifically, the connecting hole 813 can be a round hole or an oblong hole. When the connecting hole 813 is an oblong hole, it can be set to extend vertically and / or be set horizontally, which can be used for fine adjustment of the position of the first connecting plate 810 relative to the body 100.

[0049] like Figure 8 As shown, the first driven roller assembly 200 includes first driven rollers located at both ends of the machine body 100. Each first driven roller includes a cylinder 210 and half-shafts 220 snapped onto both ends of the cylinder 210. The half-shafts 220 are connected to the cylinder 210 by welding. The half-shafts 220 are snapped onto the machine body 100 via a first L-shaped groove 120 and a second L-shaped groove 812. The half-shafts 220 improve the mechanical properties of the first driven roller.
