Description

Technical Field

[0001] This utility model relates to a mesh belt conveyor, and in particular to a support strip anti-detachment mechanism and a mesh belt conveyor. Background Technology

[0002] As is well known, the conveyor chain and support bars are the core moving parts of the belt dryer, and one of the main problems of the mesh belt dryer is chain derailment.

[0003] Currently, the support bar and the conveyor chain are mostly connected by bolts (such as...). Figure 6 As shown), after long-term operation, the bolts will loosen, leading to the derailment of the support bar from the conveyor chain. For example, a conveyor support bar (publication number: CN221215672U) in Chinese Utility Model Patent includes a hollow strip-shaped portion, a transition portion, and a flat portion; both ends of the strip-shaped portion are connected to a flat portion through the transition portion; the two connecting ends of the transition portion are a wide end that mates with the strip-shaped portion and a narrow end that mates with the flat portion, respectively; the flat portion has screw holes for bolt fixing the support bar to the chain structure; another example is a leak-proof mesh belt (publication number: CN2...). (21115522U) The support bar and the conveyor chain are also connected by bolts, and the support bar is stamped. However, the mesh belt conveyor is often in a slightly shaking working environment during the conveying process, and occasionally there will be large shaking. Therefore, after long-term shaking, the bolts and nuts will loosen. Moreover, since the bolts and nuts are covered by the surrounding mesh belt, it is difficult to find and repair them. Therefore, after long-term operation, once the bolts and nuts fall off, the support bar and the conveyor chain will lose connection, which will lead to derailment. In addition, the support bar needs to be stamped multiple times, which makes its manufacturing difficult and costly. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a support bar anti-derailment mechanism and a mesh belt conveyor, so that the support bar and the conveyor chain will not derail, thus ensuring the reliability of the mesh belt conveyor operation.

[0005] The purpose of this utility model is achieved through the following technical solution: a support bar anti-detachment mechanism, including a support bar and a pair of tracks, a conveyor chain installed on the track, connecting ears spaced apart on the inner side of the conveyor chain, the support bar located between the two conveyor chains, and an insertion cavity opened at both ends of the support bar, the insertion part of the connecting ear is always inserted into the corresponding support bar's insertion cavity.

[0006] Optionally, the distance between the support bar and the baffle of the adjacent track is less than the distance between the baffle and the farthest end of the corresponding connecting ear.

[0011] Optionally, side guide wheels are provided at intervals along the conveying direction on the outer side of the conveyor chain.

[0012] Optionally, the support strip is a square tube with a connected inner cavity.

[0013] A mesh belt conveyor includes a mesh belt and a support bar anti-detachment mechanism. The mesh belt is disposed between conveyor chains, and the support bar is disposed below the mesh belt and supports the mesh belt.

[0014] The present invention has the following advantages: The anti-detachment mechanism of the support bar of the present invention, by inserting the connecting ear into the support bar, ensures that the connecting ear and the support bar will never separate, thereby preventing the support bar from derailing from the conveyor chain.

[0028] like Figure 1 and Figure 2 As shown, a support bar anti-detachment mechanism includes a support bar 6 and a pair of tracks 4, as shown. Figure 2 and Figure 5 As shown, the track 4 has an L-shaped cross-section, with a baffle in the vertical direction. A conveyor chain 2 is installed on the track 4, and the conveyor chain 2 slides on the horizontal plate of the track 4. Figure 1 , Figure 3 and Figure 4 As shown, connecting ears 3 are provided at intervals on the inner side of the conveyor chain 2, such as... Figure 2 and Figure 5 As shown, the connecting ear 3 is also an L-shaped structure, with its vertical plate connected to the conveyor chain 2, and its horizontal plate serving as the insertion part, as shown. Figure 1 As shown, the support bar 6 is located between the two conveyor chains 2. Insertion cavities are provided at both ends of the support bar 6. The insertion part of the connecting ear 3 is always inserted into the corresponding insertion cavity of the support bar 6. Therefore, even if the conveyor chain 2 deviates to the most extreme position during movement, the insertion part of its connecting ear 3 is still inserted into the corresponding insertion cavity of the support bar 6. Thus, the support bar 6 will not derail from the conveyor chain 2, ensuring the reliability of the mesh belt conveyor.

[0029] In this embodiment, as Figure 1 As shown, the distance between the support bar 6 and the baffle of the adjacent track 4 is less than the distance between the baffle and the farthest end of the corresponding connecting ear 3. Therefore, even after the outer side of the conveyor chain 2 contacts the baffle, the insertion part of the connecting ear 3 is always inserted into the insertion cavity of the support bar 6, thereby avoiding the derailment of the support bar 6 and the conveyor chain 2 and ensuring the reliability of the mesh belt conveyor.

[0030] In this embodiment, to facilitate the installation of the support strip 6, after installation, the support strip 6 can move a certain distance in the left and right directions, but this movement distance is very small. Furthermore, as... Figure 2 As shown, the connecting ear 3 and the corresponding support bar 6 are positioned by a positioning component. After the connecting ear 3 is inserted into the insertion cavity of the support bar 6, the positioning component is then installed. The positioning component makes the position between the connecting ear 3 and the support bar 6 relatively fixed. Therefore, after the mesh belt is installed, the mesh belt can move better with the drive of the conveyor chain 2.

[0031] In this embodiment, the positioning element can be used in various forms for positioning. For example, the positioning element can be a weld point, meaning that the connecting ear 3 and the support strip 6 can be welded together. However, welding makes maintenance inconvenient, so welding is usually not used between the connecting ear 3 and the support strip 6. Another example is a pin, where pin holes are provided on the connecting ear 3 and the support strip 6, and a matching pin is installed in the pin hole. However, since the mesh belt conveyor rotates, it is inconvenient to install the pin in the lower stroke during installation. Of course, to prevent the pin from falling off, the pin can be replaced with a rivet. After the rivet is installed, it is then installed between the positioning element and the connecting ear 3 using a riveting method. Similarly, whether it is welding, pins, or rivets, although they can achieve positioning between the connecting ear 3 and the support strip 6, they all have their disadvantages. Therefore, in this embodiment, the preferred method is... Figure 2 As shown, the positioning element is a self-tapping screw 5, and further, as... Figure 1 and Figure 3 As shown, the connecting ear 3 has pre-drilled small holes 8, and the top or bottom surface of the support strip 6 also has pre-drilled small holes 8. The pre-drilled small holes 8 match the size of the self-tapping screws 5. After the support strip 6 and the connecting ear 3 are inserted, the corresponding two pre-drilled small holes 8 are aligned, and then the self-tapping screws 5 are installed from top to bottom. After the self-tapping screws 5 are installed, threads will be formed at the pre-drilled small holes 8. Therefore, the self-tapping screws 5, support strip 6, and connecting ear 3 are connected by threads, and no nuts are needed. Through the self-locking function of the threads, the self-tapping screws 5 are not easy to loosen, ensuring that the positions of the support strip 6 and the connecting ear 3 are fixed. Even after prolonged use, the self-tapping screws 5 may loosen. However, since the support bar 6 and the connecting ear 3 are always in an inserted state, the support bar 6 and the conveyor chain 2 will not derail even if the self-tapping screws loosen and fall off. The positioning of the support bar 6, the connecting ear 3, and the support bar 6 is achieved by the self-tapping screws 5. This not only makes the self-tapping screws 5 easy to install and remove, but also eliminates the need for nuts. Furthermore, after the self-tapping screws 5 are installed, the upper surface of the insertion part of the connecting ear 3 can fit against the upper surface of the inner cavity of the support bar 6, thereby ensuring the horizontal height of the support bar 6 and ensuring that the conveyor chain 2 drives the mesh belt to rotate.

[0032] In this embodiment, to ensure that the conveyor chain 2 drives the mesh belt to rotate, especially when the mesh belt is in the turning area, the relative position of the mesh belt and the conveyor chain 2 is required. Therefore, taking the conveying direction of the conveyor chain 2 as the forward direction, such as... Figure 3 and Figure 5As shown, the front and rear sides of the connecting ear 3 are provided with bending parts 7. The farthest distance between the two bending parts 7 matches the width of the insertion cavity. Preferably, the bending parts 7 are bent upwards. By matching the farthest distance between the two bending parts 7 with the width of the insertion cavity, the support bar 6 cannot move back and forth relative to the connecting ear 3. When the self-tapping screw 5 is installed, the top of the bending part 7 abuts against the support bar 6. Therefore, the height of the bending part 7 can be adjusted according to the actual situation, thereby adjusting the height of the support bar 6, so that the plane where the mesh belt is located is in the plane where the center of the conveyor chain 2 is located, ensuring that the conveyor chain 2 drives the mesh belt to transport smoothly.

[0033] In this embodiment, when the conveyor chain 2 deviates from its designated path, the chain pin of the conveyor chain 2 will come into contact with the baffle of the track 4, leading to wear of the chain pin. Long-term wear of the chain pin can easily cause the conveyor chain 2 to break. To solve this technical problem, such as... Figure 1 As shown, side guide wheels 1 are arranged at intervals along the conveying direction on the outer side of the conveying chain 2. When the conveying chain 2 deviates, the side guide wheels 1 will contact the baffle of the track 4, while the chain pin will not contact the baffle, thus preventing the chain pin from wearing out and avoiding the breakage of the conveying chain 2.

[0034] Traditional support strips 6 typically require cutting during manufacturing, followed by stamping at both ends. This process is difficult and costly. In this embodiment, the support strip 6 is a square tube with interconnected internal cavities. Therefore, the support strip 6 can utilize existing profiles, which are commercially available. These profiles are then aligned and cut to create pre-drilled holes 8. This process is characterized by easy material selection, fewer processing steps, simpler processing, lower processing costs, and the elimination of stamping processes. Example

[0035] A mesh belt conveyor includes a mesh belt (not shown in the figure) and a support bar anti-detachment mechanism. The support bar anti-detachment mechanism has the same structure as the support bar anti-detachment mechanism in Embodiment 1. The mesh belt is arranged between the conveyor chains 2, and the support bars 6 are arranged below the mesh belt. The support bars 6 support the mesh belt. When the conveyor chains 2 move along the track 4, they drive the mesh belt to move. Moreover, even if the conveyor chains 2 deviate during the movement, the support bars 6 and the conveyor chains 2 will not derail, thereby ensuring the reliability of the mesh belt conveyor operation.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
