Description

Technical Field

[0001] This disclosure relates to the field of logistics conveying equipment technology, and in particular to a conveyor belt support mechanism. Background Technology

[0002] Belt drive systems rely on the friction between the belt and pulleys to transmit power and motion, and are widely used in various fields such as industrial production and logistics transportation. The pulley, as a crucial component of the belt drive system, plays a vital role in supporting and adjusting belt tension, and is essential for ensuring the stability and reliability of the belt drive.

[0003] Currently, most belt drive systems are equipped with only a single pulley. The belt wraps around the pulley, and during equipment operation, the pulley rotates with the belt to maintain its proper tension. When a single pulley malfunctions, such as due to excessive wear or bearing damage, it may fail to rotate properly or become misaligned. The belt will then lose its support and come into direct contact with the support rod beneath it. Because the support rod has a high surface hardness and is relatively rough, the belt is easily scratched or even torn during continued operation. This not only leads to premature belt failure, increasing the cost and time of belt replacement, but may also cause equipment downtime, affecting production efficiency and continuity. Summary of the Invention

[0004] This disclosure is made in view of the above-mentioned problems. This disclosure provides a conveyor belt support mechanism.

[0005] According to one aspect of this disclosure, a conveyor belt support mechanism is provided, comprising:

[0006] A first support device, the first support device including a top pulley, the top pulley being used to support the conveyor belt;

[0007] The second support device is provided in front of the first support device, which includes a top pulley for supporting the conveyor belt. The top pulley is positioned along the direction of movement of the conveyor belt. The apex height of the top pulley of the second support device is lower than that of the top pulley of the first support device.

[0008] Furthermore, according to one aspect of the conveyor belt support mechanism of this disclosure, both the first support device and the second support device include:

[0009] The two top pulleys are identical in structure and symmetrically arranged on the left and right sides.

[0010] A support rod, with two top pulleys disposed on the top of the support rod, and an axle on the top of the support rod supporting the top pulleys, and a bearing disposed between the top pulleys and the axle;

[0011] The mounting base is located at the bottom end of the support rod and is used to connect the frame of the logistics conveying equipment.

[0012] Furthermore, according to one aspect of the conveyor belt support mechanism of this disclosure, the apex height of the top pulley of the second support device is higher than the apex height of the support rod of the first support device.

[0013] Furthermore, according to one aspect of the conveyor belt support mechanism of this disclosure, the outer circumferential surface of the top pulley includes:

[0014] A first support surface, which is a cylindrical surface, is located on the side of the top pulley near the support rod.

[0015] The second support surface is a conical surface. The first support surface is located on the side of the top pulley away from the support rod. The larger diameter end of the second support surface is connected to the first support surface.

[0016] Furthermore, according to one aspect of the conveyor belt support mechanism of this disclosure, the first support device and the second support device further include:

[0022] Furthermore, according to one aspect of the conveyor belt support mechanism of this disclosure, the apex height of the top pulley of the second support device is 40-60 mm lower than the apex height of the top pulley of the first support device;

[0023] The second support device is spaced 1.5-2m apart from the first support device.

[0024] Furthermore, according to one aspect of the conveyor belt support mechanism of this disclosure, the top pulley is made entirely of a wear-resistant material, or is made of a metal hub wrapped with a wear-resistant layer.

[0025] According to the conveyor belt support mechanism of the present disclosure, by setting two sets of support devices, when the top pulley of the first support device fails, the top pulley of the second support device can promptly support the conveyor belt, preventing the conveyor belt from contacting other hard objects, greatly reducing the risk of the conveyor belt being scratched or torn, extending the service life of the conveyor belt, and reducing equipment downtime and maintenance costs caused by conveyor belt damage.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0034] This disclosure provides a conveyor belt support mechanism for logistics conveying equipment. The logistics conveying equipment is equipped with a conveyor belt, which can also be called a belt. By setting two sets of support devices, when the top pulley of the first support device fails, the top pulley of the second support device can promptly support the conveyor belt, preventing the conveyor belt from contacting other hard objects and greatly reducing the risk of the conveyor belt being scratched or torn.

[0035] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0036] like Figure 1 , Figure 2 As shown, this embodiment of the present disclosure provides a conveyor belt support mechanism, including: a first support device 100 and a second support device 200;

[0037] The first support device 100 includes a top pulley, which is used to support the conveyor belt 300;

[0038] The first support device 100 includes a top pulley for supporting the conveyor belt 300 along the direction of movement of the conveyor belt 300, such as... Figure 1 As indicated by the arrow in the diagram, the second support device 200 is located in front of the first support device 100, i.e., in the direction from which the conveyor belt 300 is driven. The height of the top pulley of the second support device 200 is lower than the height of the top pulley of the first support device 100.

[0039] Figure 1 The top pulley of the second support device 200 shown has a peak height of N, and the top pulley of the first support device 100 has a peak height of M, with N being appropriately lower than M.

[0040] When the logistics conveying equipment is running normally, the top pulley of the first support device 100 supports the movement of the conveyor belt 300. The top pulley of the second support device 200 is slightly lower and does not contact the conveyor belt 300. When the top pulley of the first support device 100 malfunctions, such as being misaligned or falling off, the conveyor belt 300 will automatically fall onto the top pulley of the second support device 200, and the top pulley of the second support device 200 will support the movement of the conveyor belt 300, thereby ensuring the normal operation of the conveyor belt 300.

[0041] The conveyor belt support mechanism of this embodiment is provided with two sets of support devices. When the top pulley of the first support device fails, the top pulley of the second support device can promptly support the conveyor belt, preventing the conveyor belt from contacting other hard objects. This greatly reduces the risk of the conveyor belt being scratched or torn, extends the service life of the conveyor belt, and reduces equipment downtime and maintenance costs caused by conveyor belt damage.

[0042] The first support device 100 and the second support device 200 have basically the same structure. The first support device 100 will be used as an example for detailed description below. The specific structure of the second support device 200 can be referred to the first support device 100.

[0043] In some possible implementations, such as Figure 1 , Figure 2 As shown, the first support device 100 includes: two top pulleys, a support rod 2, and a mounting base 5;

[0044] The two top pulleys have the same structure and are symmetrically arranged, namely the first top pulley 1 and the second top pulley 7. The two top pulleys can stably support the conveyor belt 300 and prevent the conveyor belt 300 from deviating to the left or right. However, if one of the first top pulley 1 and the second top pulley 7 is misaligned or falls off, the conveyor belt 300 may come into contact with the support rod 2, and the top of the support rod 2 will cause scratches or tears to the conveyor belt 300.

[0045] Two top pulleys are set on the top of the support rod 2. The top of the support rod 2 is provided with a wheel axle 8 to support the top pulleys. A bearing is provided between the top pulleys and the wheel axle 8 to ensure that the top pulleys can rotate flexibly. Both the support rod 2 and the wheel axle 8 are made of metal, such as steel. The wheel axle 8 can be fixed to the top of the support rod 2 by thread or welding.

[0046] Mounting base 5 is located at the bottom end of support rod 2. Mounting base 5 is used to connect to the frame of the logistics conveying equipment. Mounting base 5 is made of metal, such as steel. Mounting base 5 and the frame of the logistics conveying equipment can be fixed by threads or welding. Figure 1 The mounting base 5 shown is equipped with bolts 4, which are used to connect and fix it to the frame of the logistics conveying equipment, ensuring a firm installation and facilitating maintenance.

[0047] In some possible implementations, such as Figure 1 , Figure 2 As shown, the apex height of the top pulley of the second support device 200 is higher than the apex height of the support rod 2 of the first support device 100. The top pulley of the second support device 200 includes a first top pulley 9 and a second top pulley 14. Figure 1 The top pulley of the second support device 200 shown in the diagram has a apex height of N, and the support rod 2 of the first support device 100 has a apex height of L. N is appropriately higher than L. When either the first top pulley 1 or the second top pulley 7 of the first support device 100 shifts position or falls off, the conveyor belt 300 is immediately supported by the top pulley of the second support device 200 and will not come into contact with the support rod 2, thereby reducing the risk of the conveyor belt 300 being scratched or torn.

[0048] In some possible implementations, such as Figure 2 , Figure 3 As shown, the first top pulley 1 and the second top pulley 7 have the same structure and are arranged symmetrically on the left and right. Taking the first top pulley 1 as an example, the outer circumferential surface of the first top pulley 1 includes: a first support surface 101 and a second support surface 102.

[0049] The first support surface 101 is a cylindrical surface, and the first support surface 101 is located on the side of the first top pulley 1 near the support rod 2;

[0050] The second support surface 102 is a conical surface. The first support surface 101 is located on the side of the first top pulley 1 away from the support rod 2. The larger diameter end of the second support surface 102 is connected to the first support surface 101. A rounded transition can be provided at the connection to avoid sharp structures damaging the conveyor belt 300.

[0051] After the first top pulley 1 and the second top pulley 7 are combined, they present a structure that is high in the middle and low on both sides. The conveyor belt 300 also presents a shape that is high in the middle and low on both sides under the support of the first top pulley 1 and the second top pulley 7.

[0052] In some possible implementations, such as Figure 1 , Figure 2 As shown, the first support device 100 also includes: a reinforcing rib 3;

[0053] The reinforcing rib 3 is set at the bottom end of the support rod 2. The reinforcing rib 3 connects the support rod 2 and the mounting base 5. It can be fixed by welding to improve the connection strength between the support rod 2 and the mounting base 5 and prevent the support rod 2 from tilting and being damaged after long-term use. Two reinforcing ribs 3 can be symmetrically set on the left and right sides of the support rod 2.

[0054] In some possible implementations, the support rod 2 can adjust the support height. For example, the support rod 2 is a screw, and the mounting base 5 is provided with a corresponding insertion hole. The bottom end of the screw extends into the insertion hole, and nuts are provided on both the upper and lower sides of the mounting base 5. By rotating the nuts to adjust the height of the screw, the support height of the top pulley can be adjusted to achieve a suitable support height for the conveyor belt 300. After adjustment, the screw can be locked with the nuts.

[0055] In addition, hydraulic or pneumatic adjustment devices can be used to adjust the height of the support rod, especially the height of the support rod 10 in the second support device 200. For example, the support rod can be made of the piston rod of a pneumatic cylinder or the piston rod of a hydraulic cylinder. The purpose is to achieve precise adjustment of the height of the top pulley to adapt to different working conditions.

[0056] In some possible implementations, such as Figure 1 , Figure 2 As shown, the first support device 100 also includes: a shock-absorbing pad 6;

[0057] The shock-absorbing pad 6 is located below the mounting base 5. For example, a shock-absorbing rubber pad can be used to reduce the impact of vibration on the top pulley during the operation of the logistics conveying equipment.

[0058] In some possible implementations, such as Figure 1 , Figure 2 As shown, the mounting base of the first support device 100 and the mounting base of the second support device 200 are connected as one piece, for example, they can be made of a steel plate, which is convenient to maintain the height difference and spacing between the second support device 200 and the first support device 100, and also has sufficient strength and rigidity.

[0059] In some possible implementations, such as Figure 1 , Figure 2 As shown, the height of the top pulley of the second support device 200 is 40-60mm lower than the height of the top pulley of the first support device 100.

[0060] Figure 1 The top pulley height of the second support device 200 shown is N, and the top pulley height of the first support device 100 is M. N is 40-60mm lower than M, and 50mm can be selected because the top pulleys of the first support device 100 and the second support device 200 have the same size. If the height of the support rod 2 is 1000mm, the height of the support rod 10 is 950mm.

[0061] In some possible implementations, such as Figure 1 , Figure 2 As shown, the second support device 200 is spaced 1.5-2m apart from the first support device 100.

[0062] Figure 1 The second support device 200 shown is spaced S from the first support device 100, and S can be selected as 1.8m.

[0063] By selecting the dimensions mentioned above, it is ensured that when the top pulley of the first support device 100 is working normally, the top pulley of the second support device 200 will not interfere with the normal operation of the conveyor belt 300, and when the top pulley of the first support device 100 fails, the conveyor belt 300 can smoothly transition to the top pulley of the second support device 200.

[0064] In some possible implementations, the top pulley is made entirely of a wear-resistant material, such as an engineering plastic top pulley, like polyoxymethylene (POM). These materials have good wear resistance and a certain strength, which can meet the requirements of the top pulley for supporting and rotating the conveyor belt 300.

[0065] Alternatively, the top pulley can be made by wrapping a metal hub with a wear-resistant layer, which can be made of high-strength rubber to ensure that the top pulley has good wear resistance and load-bearing capacity.

[0066] The conveyor belt support mechanism according to an embodiment of the present disclosure has been described above with reference to the accompanying drawings, and has the following advantages:

[0067] Effective protection of the conveyor belt: When the top pulley of the first support device fails, the top pulley of the second support device can promptly take over the conveyor belt, preventing the conveyor belt from contacting the support rod. This greatly reduces the risk of the conveyor belt being scratched or torn, extends the service life of the conveyor belt, and reduces equipment downtime and maintenance costs caused by conveyor belt damage.

[0068] Easy to install and highly adaptable: The second support device is installed via a mounting base, requiring no modification to the original equipment's main structure, making the installation process simple and quick. Simultaneously, the height of the support rod meets actual site requirements, ensuring the top pulley of the second support device is in the optimal protective position.

[0069] Improved system reliability: This protective structure enhances the stability of the conveyor belt drive system in the event of a top pulley failure, reduces cascading failures caused by conveyor belt damage, improves the reliability and continuity of the entire equipment operation, and helps ensure smooth production.
