Description

Technical Field

[0001] This utility model relates to the field of belt conveyor equipment technology, and more specifically, to a knife-edge belt transition mechanism. Background Technology

[0002] In industrial production, belt conveyor systems are widely used due to their high efficiency and convenience in material handling. However, when two asynchronous conveyor belts are involved in coordinating to complete a transportation task, many challenges often arise.

[0003] Typically, when two asynchronous conveyor belts approach each other at their ends to complete their transport task, the gap may be too large. This problem can cause instability in the material during the transition, especially for smaller items, which are highly likely to fall between the two conveyor belts, resulting in material loss and production interruption. At the same time, reducing the gap to ensure the continuity of transport presents new challenges.

[0004] In some existing belt conveyor systems, if bearing assemblies with excessively large diameters are used, an inverted V-shaped drop zone will form near the conveyor belt. This structure is detrimental to smooth transport; materials are prone to bumping and slipping when passing through this area, severely affecting the stability and reliability of the transport. Furthermore, to achieve a smaller spacing, the long shaft cannot be too thick. However, during operation, the long shaft is subjected to the tension of the conveyor belt and tends to move towards the fixed crossbar. If the long shaft cannot be effectively supported and kept long and straight, it will further affect the normal operation of the belt and the smooth transport of materials.

[0005] Traditional belt conveyor transition mechanisms are ineffective in solving the aforementioned problems and cannot meet the stringent requirements of modern industrial production for efficient and stable material transport. Therefore, there is an urgent need to develop a new type of knife-edge belt conveyor transition mechanism to achieve reasonable spacing control at the ends of two asynchronous conveyor belts, ensuring smooth transport and improving production efficiency and quality. Utility Model Content

[0006] Based on the above-mentioned technical problems, this utility model proposes a knife-edge belt transition mechanism.

[0007] A knife-edge belt transition mechanism, comprising:

[0008] The support frame is equipped with a horizontally extending support beam, with side beams at both ends of the support beam;

[0009] The gap adjustment component includes:

[0010] The long axis is parallel to the front side of the supporting crossbeam;

[0011] A shaft support unit is installed on a support beam and connected to a long shaft.

[0012] The bearing assembly is fitted onto the outside of the long shaft;

[0013] The shaft support unit can adjust the distance between the long shaft and the support beam, and the bearing assembly forms the wrapping path at the end of the conveyor belt.

[0014] The support mechanism includes a roller rotatably mounted on the rear side of the support beam, with both ends of the roller rotatably mounted on the side beam, and the upper and lower sides of the roller providing contact support to the conveyor belt.

[0015] Preferably, the shaft support unit comprises:

[0016] Multiple top rod adjustment components are vertically installed on the support beam;

[0017] The connecting structure is located between the end of the push rod screw and the long shaft;

[0018] The spatial position of the long shaft can be changed synchronously by rotating the top screw.

[0019] Preferably, the push rod adjusting member includes:

[0020] The top rod thread is inserted into the round hole of the supporting crossbeam;

[0021] The lock nut is fitted onto the top rod thread and is in close contact with the support beam.

[0022] The connection structure is a polygonal meshing pair, which includes an array of grooves along the long axis and a matching boss at the end of the push rod.

[0023] Preferably, the groove is a regular polygonal blind hole, and the cross-section of the boss is a corresponding regular polygon.

[0024] Preferably, the diameter of the roller is greater than the thickness of the supporting beam, and the roller supports the conveyor belt so that the conveyor belt does not come into contact with the supporting beam.

[0025] Beneficial effects:

[0026] 1. Precise Spacing Control: Through the ingenious design of the top rod adjustment component and polygonal meshing pair in the shaft support unit, the position of the long shaft can be precisely adjusted, thereby precisely adjusting the spacing between the belt and the support beam. This precise spacing control effectively solves the problem of deformation at the ends of two asynchronous conveyor belts, ensuring stable transportation of materials with a small spacing and preventing small objects from falling between the two conveyor belts.

[0027] 2. Smooth Transportation Guarantee: The reasonable design of the bearing assembly diameter avoids the formation of an inverted V-shaped drop zone near the conveyor belt, enabling the conveyor belt to achieve a smooth transition. At the same time, the effective support and flexible rotation of the rollers for the conveyor belt reduce the resistance and wear of the conveyor belt, further ensuring the smooth transportation of materials in the transition area and improving the stability and reliability of the entire belt conveyor system.

[0028] 3. Enhanced stability of the long shaft: The top rod adjustment component in the shaft support unit can provide reliable support for the long shaft, effectively resisting the tension of the conveyor belt during operation, ensuring that the long shaft remains long and straight. This not only helps maintain the normal operation of the belt, but also extends the service life of the long shaft and related components, and reduces the maintenance cost of the equipment.

[0029] 4. Simple and efficient operation: The design of the gap adjustment component allows operators to adjust the position of the long shaft by simply rotating the top screw. The operation process is simple and quick, requiring no complicated tools or professional skills, which greatly reduces the time and manpower required for adjustment, improves production efficiency, and meets the needs of modern industrial production for high-efficiency equipment.

Detailed Implementation

[0035] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] like Figures 1-4 The blade belt transition mechanism shown consists of three main parts: a support frame, a gap adjustment component, and a support mechanism.

[0037] Support frame: As the basic support part of the mechanism, the support frame is equipped with a horizontally extending support beam 1, with side beams 2 at both ends. The support beam 1 provides lateral stability support for the entire mechanism.

[0038] Gap adjustment component:

[0039] Long shaft 5: Its two ends are fixedly installed on the front side of the support beam 1 through the connecting seat 4 and are set parallel to the support beam 1. It is a key component for gap adjustment. Since it will be subjected to the tension of the conveyor belt 3 during operation and tends to move towards the fixed crossbar, it needs precise support and adjustment. The diameter design of the long shaft 5 fully considers avoiding the formation of an inverted V-shaped drop zone 10 that is not conducive to smooth transportation near the conveyor belt 3. It also takes into account the cooperation with other components to achieve effective control of the gap of the conveyor belt 3.

[0040] Shaft support unit: Installed on the support beam 1 and connected to the long shaft 5, its design purpose is to adjust the distance between the long shaft 5 and the support beam 1, while ensuring that the long shaft 5 remains long and straight during operation. The shaft support unit includes multiple push rod adjusting components and connecting structures. The multiple push rod adjusting components are vertically installed on the support beam 1. The push rod adjusting component consists of push rod screws 7 and locking nuts 9. The push rod screws 7 are inserted into the round holes of the support beam 1, and the locking nuts 9 are fitted onto the push rod screws 7, tightly against the support beam 1. When it is necessary to adjust the position of the long shaft 5, rotate the locking nuts 9, and the push rod screws 7... It will extend or retract from the round hole of the supporting beam 1, and then drive the long shaft 5 to move through the connecting structure. At this time, the push rod thread 7 and the round hole are not threaded. After the adjustment is completed, the position of the push rod thread 7 is fixed to ensure the stability of the long shaft 5. The connecting structure adopts a polygonal meshing pair, including a groove 5-1 on the circumference of the long shaft 5 and a matching boss (not shown in the figure) on the end of the push rod thread 7. The groove is a regular polygonal blind hole, and the cross section of the boss is a corresponding regular polygon. This unique design can achieve a stable connection between the push rod thread 7 and the long shaft 5, and prevent the push rod thread 7 from rotating when the locking nut 9 is turned.

[0041] Bearing assembly 6: Sleeved on the outside of the long shaft 5, its function is to form the covering path at the end of the conveyor belt 3. When selecting bearing assembly 6, the problem of avoiding the formation of an inverted V-shaped drop zone 10 that is not conducive to smooth transportation due to excessive diameter at the close proximity of the conveyor belt 3 was fully considered. The bearing assembly 6 with a suitable diameter can enable the conveyor belt 3 to achieve a smooth transition when passing through the long shaft 5, reduce friction and wear, and at the same time ensure that smaller objects will not fall between the two conveyor belts 3, thus ensuring the stability and continuity of material transportation.

[0042] Support mechanism: The support mechanism includes a roller 8 rotatably mounted on the rear side of the support beam 1. The two ends of the roller 8 are rotatably mounted on the side beam 2. The upper and lower sides of the roller 8 provide contact support for the conveyor belt 3. The diameter of the roller 8 is specially designed to be greater than the thickness of the support beam 1. This design allows the roller 8 to effectively support the conveyor belt 3, preventing the conveyor belt 3 from contacting the support beam 1 and avoiding direct friction between the conveyor belt 3 and the support beam 1, thus further protecting the conveyor belt 3. At the same time, the rotatable nature of the roller 8 allows it to rotate flexibly with the operation of the conveyor belt 3, reducing the resistance to the conveyor belt 3 and ensuring the smooth operation of the conveyor belt 3 in the transition area. This helps to achieve a smooth connection between the ends of two asynchronous conveyor belts 3 and the smooth transportation of materials.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
