Description

Technical Field

[0001] This application relates to the field of long-stroke double-speed chain conveying, specifically to a double-speed chain conveying structure and a double-speed chain conveying line. Background Technology

[0002] Currently, LCD panels undergo optical appearance inspection and aging tests during the manufacturing process. During aging testing, the LCD panels are conveyed into an aging room via a conveyor line. Inside the aging room, the panels are required to be powered on and subjected to high-temperature aging tests for a specific period before being conveyed out to complete the aging test. Due to the considerable length of the aging room, the conveyor lines involve relatively long and numerous speed-measuring chains and profiles. The high temperatures place high demands on the structure and materials of these chains and profiles. The contact surfaces of these chains and profiles experience wear over long periods, necessitating regular maintenance and replacement.

[0003] In related technologies, the double-speed chain of a conventional conveyor line directly contacts the support shoulder inside the profile trough to bear the weight of the entire conveyed goods. The contact surface between the double-speed chain and the support shoulder of the profile wears out quickly. After a certain degree of wear, the double-speed chain and the profile need to be replaced. Furthermore, the structure of the profile is open at only two ends. The double-speed chain can only be replaced and repaired by pulling it out from both ends of the profile. When the conveyor line is long, problems such as double-speed chain jamming, heavy chain that is difficult to pull out, and inability to pull out and replace the chain may occur. Maintenance is difficult and costly.

[0004] Therefore, it is necessary to design a new double-speed chain conveyor structure and double-speed chain conveyor line to overcome the above problems. Utility Model Content

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0031] This application provides a double-speed chain conveyor structure and double-speed chain conveyor line, which can solve the technical problems of difficult and costly maintenance of double-speed chains and profiles in related technologies.

[0032] See Figure 1 and Figure 2 As shown, an embodiment of this application provides a double-speed chain conveyor structure, which may include: a support body 11, wherein the support body 11 is provided with an installation groove 111, and a first wear-resistant strip 2 is pressed into the installation groove 111, the installation groove 111 has an open opening extending along the longitudinal direction of the support body 11, and protective covers 3 are detachably installed on opposite sides of the open opening on the support body 11; a double-speed chain 4, which is installed in the installation groove 111 and supported by the first wear-resistant strip 2.

[0033] In this embodiment, the support body 11 is preferably made of aluminum profile and is elongated to facilitate long-stroke transportation. The support body 11 may have two mounting slots 111 distributed vertically. Part of the double-speed chain 4 is located in the upper mounting slot 111, and the other part is located in the lower mounting slot 111. Since the double-speed chain 4 in the upper mounting slot 111 mainly bears the weight of the goods during the transportation process, the first wear-resistant strip 2 is set in the upper mounting slot 111, and the first wear-resistant strip 2 may not be set in the lower mounting slot 111. At the same time, the first wear-resistant strip 2 is preferably set at the contact surface between the double-speed chain 4 and the support body 11, so that the double-speed chain 4 basically contacts the first wear-resistant strip 2 and basically does not contact the support body 11. The double-speed chain conveying structure in this embodiment is mainly used in long-stroke double-speed chain conveyor lines and heavy-load transportation of goods; the first wear-resistant strip 2 is preferably made of soft plastic.

[0034] In this embodiment, a first wear-resistant strip 2 is pressed into the mounting groove 111 of the support body 11. During operation, the double-speed chain 4 directly contacts the first wear-resistant strip 2 and basically does not contact the support body 11, which reduces direct wear between the double-speed chain 4 and the support body 11 and avoids the need to replace the support body 11. Furthermore, the first wear-resistant strip 2 is made of soft plastic, and the rollers of the double-speed chain 4 are also made of plastic. The contact between the soft plastic first wear-resistant strip 2 and the rollers of the double-speed chain 4 can reduce the wear of the rollers of the double-speed chain 4. The coefficient of friction of the soft plastic first wear-resistant strip 2 is also smaller than that of aluminum profiles, so the friction damage to the double-speed chain 4 is also relatively reduced, which can increase the service life of the double-speed chain 4. At the same time, the cover 3 is detachably installed on the support body 11. When the double-speed chain 4 needs to be replaced, the cover 3 can be removed, leaving the double-speed chain 4 in an open state. The double-speed chain 4 can be replaced from the open opening, reducing maintenance time and labor costs, and solving the technical problems of difficult and costly maintenance of the double-speed chain 4 and profiles in related technologies.

[0035] Furthermore, in one embodiment, see... Figure 1 and Figure 3 As shown, the support body 11 is provided with a pressure groove 112. The first wear-resistant strip 2 includes a support portion 21 and a pressing portion 22 connecting the support portion 21. The pressing portion 22 is pressed into the pressure groove 112, and the double-speed chain 4 is supported on the support portion 21. In this embodiment, the support portion 21 is preferably horizontally plate-shaped, and the pressing portion 22 is preferably vertically plate-shaped. The pressing portion 22 is arranged approximately perpendicular to the support portion 21. The pressing portion 22 is pressed into the pressure groove 112, and the pressing portion 22 is used to fix the support portion 21 to the support body 11. The horizontally extending support portion 21 can stably support the double-speed chain 4. In other embodiments, other methods can also be used to fix the first wear-resistant strip 2 to the support body 11, such as bolt fixing.

[0036] Based on the above technical solution, in one embodiment, see [reference needed]. Figure 1 and Figure 3As shown, an arc-shaped protrusion 113 protrudes from the groove 112, and the pressing part 22 is provided with an arc-shaped groove 221. The pressing part 22 forms a blocking part 222 on one side of the arc-shaped groove 221. The blocking part 222 is located on the side of the pressing part 22 away from the support part 21. The pressing part 22 is pressed into the groove 112, and the arc-shaped groove 221 is engaged with the arc-shaped protrusion 113. The blocking part 222 stops on one side of the arc-shaped protrusion 113. In this embodiment, an arc-shaped protrusion 113 is provided on one side of the pressing groove 112, and an arc-shaped groove 221 is provided on the corresponding side of the pressing part 22. After the pressing part 22 is pressed into the pressing groove 112, the arc-shaped groove 221 is just stuck on the arc-shaped protrusion 113, so that the arc-shaped groove 221 and the arc-shaped protrusion 113 cooperate with each other to keep the pressing part 22 stuck in the pressing groove 112 and not easy to come out. Furthermore, by providing a blocking part 222 below the arc-shaped groove 221, the arc-shaped protrusion 113 can block above the blocking part 222, further preventing the pressing part 22 from coming out of the pressing groove 112. At the same time, the use of the arc-shaped protrusion 113 and the arc-shaped groove 221 makes it easy for the pressing part 22 to be smoothly pressed into the pressing groove 112.

[0037] See Figure 1 As shown, preferably, the support body 11 has a support shoulder 114 protruding into the mounting groove 111, the pressing groove 112 is formed in the support shoulder 114, and the support part 21 is sandwiched between the support shoulder 114 and the speed-doubling chain 4; the arc-shaped protrusion 113 is connected to the top surface of the support shoulder 114, and the surface of the arc-shaped protrusion 113 is tangent to the top surface of the support shoulder 114; the arc-shaped groove 221 is located at the connection between the pressing part 22 and the support part 21. In this embodiment, the support shoulder 114, as a protruding part within the mounting groove 111, can support the first wear-resistant strip 2 to a certain height. Furthermore, the arc-shaped protrusion 113 is positioned at the top surface of the support shoulder 114 and is tangent to the top surface. With this configuration, when the first wear-resistant strip 2 is installed into the pressing groove 112, it can rotate from the top surface of the support shoulder 114 around the center of the arc-shaped protrusion 113 and along the curvature direction of the surface of the arc-shaped protrusion 113, gradually pressing it into the pressing groove 112. When the first wear-resistant strip 2 is removed from the pressing groove 112, its rotation direction is opposite to its pressing direction. That is, in this embodiment, the first wear-resistant strip 2 can be directly rotated and pressed into the pressing groove 112, which facilitates disassembly and assembly.

[0038] In other embodiments, the arc-shaped protrusion 113 may also be located below the top surface of the support shoulder 114 and spaced apart from the support shoulder 114.

[0039] Furthermore, in some embodiments, see Figure 1As shown, the cover 3 is made of aluminum alloy and is fastened to the support body 11 by screws 5. In this embodiment, multiple screws 5 can be spaced along the extension direction of the support body 11 to fasten the cover 3 to the support body 11, which can effectively prevent the cover 3 from shifting. At the same time, the cover 3 is made of aluminum alloy, which is not only lightweight, but also different from the plastic bottom of the conveying pallet 7, thus reducing wear.

[0040] Furthermore, in one embodiment, see... Figure 1 and Figure 2 As shown, one side of the support body 11 integrally extends to form an extension body 12. A second wear-resistant strip 6 is installed on the extension body 12. The second wear-resistant strip 6 is located above the cover 3 and spaced apart from it. In this embodiment, the extension body 12 integrally extends upward from the outer side of the support body 11, and the second wear-resistant strip 6 is installed on the inner side of the extension body 12 (i.e., the side closer to the cover 3). There is a gap between the second wear-resistant strip 6 and the cover 3. This arrangement allows for convenient removal and installation of the cover 3 without disassembling the second wear-resistant strip 6, as it can be easily removed and installed through the gap below the second wear-resistant strip 6. In this embodiment, the second wear-resistant strip 6 is preferably made of soft plastic.

[0041] See Figure 5 As shown, this application embodiment also provides a double-speed chain conveyor line, which includes the above-mentioned double-speed chain conveyor structure. The double-speed chain conveyor line includes at least two support bodies 11, which are arranged parallel to each other at intervals. Each support body 11 is equipped with a double-speed chain 4, and a conveyor tray 7 (PLT) is provided on the double-speed chain 4. The conveyor tray 7 includes a first tray 71 and a second tray 72. The tops of the first tray 71 and the second tray 72 are connected to each other, and their bottoms are respectively supported on the two double-speed chains 4 arranged parallel to each other at intervals (see...). Figure 5 and Figure 6 (As shown). In this embodiment, two support bodies 11 are used as an example for explanation. The two support bodies 11 are arranged parallel to each other and spaced apart. Each support body 11 is equipped with a speed-multiplying chain 4. The first pallet 71 of the conveying pallet 7 is supported on the speed-multiplying chain 4 of one of the support bodies 11, and the second pallet 72 is supported on the speed-multiplying chain 4 of the other support body 11. The goods to be tested can be placed on both the first pallet 71 and the second pallet 72. At the same time, the tops of the first pallet 71 and the second pallet 72 are connected to each other, so that the first pallet 71, the second pallet 72 and the support body 11 form a triangular structure, which makes the first pallet 71 and the second pallet 72 more stable during the conveying process. The speed-multiplying chain conveying structure in this embodiment can adopt the speed-multiplying chain conveying structure in any of the above embodiments and achieve the corresponding functions, which will not be described in detail here.

[0042] Furthermore, in some embodiments, see Figure 5 As shown, at least two of the support bodies 11 are connected by connecting rods, and each connecting rod is equipped with a blocking cylinder 10, which is used to block the conveyor pallet 7. In this embodiment, the two support bodies 11 are connected by multiple connecting rods, which are arranged at intervals along the longitudinal direction of the support bodies 11. Blocking cylinders 10 can be fixed on some of the connecting rods, and the blocking cylinders 10 can be controlled to extend upwards to position and intercept the conveyor pallet 7 at the desired stopping position.

[0043] Preferably, one end of each of the two support bodies 11 is provided with a drive motor 9, which can drive the speed-multiplying chain 4 on the two support bodies 11 to move synchronously via a drive shaft.

[0044] Furthermore, in one embodiment, see... Figure 4 As shown, a guide block 8 is fixedly provided at one end of the support body 11 of the double-speed chain conveyor structure, and the double-speed chain 4 is supported by the guide block 8. In this embodiment, a guide block 8 is provided at one end of each support body 11. The guide block 8 is located at the bottom of the support body 11 and is used to guide the double-speed chain 4 into the mounting groove 111 below.

[0045] This application changes the upper part of the support body 11 to an open mounting groove 111, and solves the problems of profile wear and difficulty in maintenance and replacement of the double speed chain 4 by using a detachable cover 3 and adding a first wear-resistant strip 2 on the contact surface between the double speed chain 4 and the support body 11.
