Description

Technical Field

[0001] This utility model relates to the field of double-speed chain conveyor technology, specifically a double-speed chain conveyor track. Background Technology

[0002] The double-speed chain conveyor works by using the speed-increasing function of the chain to rapidly move the tooling plates supporting the goods, stopping them at corresponding operating positions via stoppers; or by using corresponding commands to complete accumulation, transfer, indexing, and dedicated line functions. It uses specially treated extruded aluminum alloy profiles as guide rails, providing excellent stability and durability during transport, making it suitable for high-volume continuous production and widely used in production lines of various electronics, electrical appliances, and electromechanical industries.

[0003] The existing technology, patent application number 202120587971.6, entitled "Double-Speed ​​Chain Conveyor Track," includes a track body and a detachable load-bearing guide rail. The track body comprises a lower part and an upper part; the lower part is a hollow structure with four closed sides, while the upper part is a hollow structure with an open top, consisting of a base plate and two vertical plates on either side. The detachable load-bearing guide rail includes a horizontal base and a left and right vertical beam connected vertically to the horizontal base. The detachable load-bearing guide rail is detachably connected to the base plate of the upper part of the track body. This technical solution uses replaceable wear-resistant guide rails, which can be replaced individually when worn, eliminating the need to replace the entire track, thus reducing operating costs. However, the load-bearing guide rail is fixed with connecting screws, requiring individual tightening and loosening of each screw during disassembly, resulting in time-consuming and labor-intensive maintenance or replacement. Furthermore, the screws are prone to loosening under vibration, affecting track positioning accuracy. In addition, existing guide rails lack a structure to suppress the impact noise of chain rollers, which generates noise when running at high speeds, making it difficult to meet the requirements of cleanrooms or medical environments. To address this, we propose a double-speed chain conveyor track. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed chain conveyor track to address the problems mentioned in the background art, where the load-bearing section guide rail is fixed with connecting screws. Disassembly requires tightening and loosening each screw individually, leading to time-consuming and labor-intensive maintenance or replacement. Furthermore, the screws are prone to loosening under vibration, affecting the track's positioning accuracy. In addition, existing guide rails lack a structure to suppress impact noise from the chain rollers, resulting in noise during high-speed operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-speed chain conveyor track, comprising a track body and a mounting base, wherein the mounting base is located inside the track body, two plastic chain covers are slidably connected to the top of the track body, a positioning frame is fixedly connected to the bottom of the inner cavity of the track body, an installation chamber is slidably connected to the bottom of the inner cavity of the positioning frame, two gear driven screws are rotatably connected to the inner wall of the installation chamber, one end of the gear driven screw extends into the interior of the installation chamber, a threaded sleeve is screwed onto the outer side of the gear driven screw, a positioning plate is fixedly connected to one end of the threaded sleeve, and the positioning plate is engaged with the positioning frame.

[0006] As a further description of the above technical solution:

[0007] A gear drive rod is rotatably connected to one side of the installation chamber. One end of the gear drive rod passes through the installation chamber and extends into the inner cavity of the installation chamber, and the other end of the gear drive rod is engaged with the gear driven screw.

[0008] As a further description of the above technical solution:

[0009] The bottom of the inner cavity of the mounting base is fixedly connected to a base plate, and the base plates are evenly distributed in sequence. A rubber seat is fixedly connected to the top of the base plate.

[0010] As a further description of the above technical solution:

[0011] A friction rod is fixedly connected to the top of the rubber seat, and the friction rods are evenly distributed in sequence. A rubber plate is slidably connected to the outer side of the friction rod.

[0012] As a further description of the above technical solution:

[0013] A friction sleeve is fixedly connected to the top of the rubber plate, and the friction sleeves are evenly distributed in sequence, with the inner side of the friction sleeve in contact with the friction rod.

[0014] As a further description of the above technical solution:

[0015] The top of the base plate and the bottom of the rubber plate are both fixedly connected with repulsive magnets. The top of the rubber plate is fixedly connected with a connecting rod, and the top of the connecting rod is fixedly connected with a load-bearing guide rail.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This double-speed chain conveyor track is designed to be installed by sliding the installation chamber into the positioning frame. Then, rotating the gear drive rod drives the meshing gear driven screw to rotate, causing the threaded sleeve mounted on the gear driven screw to move along with the rotation of the gear driven screw. This moves the positioning plate mounted on the threaded sleeve to contact and engage with the positioning frame, fixing the position of the installation chamber and thus securing the load-bearing guide rail above the installation chamber. Disassembly of the installation chamber is achieved by reversing the gear drive rod, allowing for quick and convenient installation and disassembly of the load-bearing guide rail.

[0018] 2. In this double-speed chain conveyor track, when the load-bearing guide rail is under pressure, pressure is applied to the connecting rod at the bottom, causing the rubber plate to descend. This causes the friction sleeve on the descending plate to rub against the friction rod, generating damping. At the same time, as the rubber plate descends, the repulsive magnets on the rubber plate come closer to the repulsive magnets installed on the base plate, generating a repulsive force. This prevents the load-bearing guide rail from being compressed and causing the bottom structure to collide and generate noise. Furthermore, when the rubber plate descends to the bottom, it comes into contact with the rubber seat and is squeezed, further preventing noise generation. Thus, the noise generated by the load-bearing guide rail during operation can be effectively reduced. Attached Figure Description

Please refer to [link / reference]. Figure 1-4 It includes the track body 100 and the mounting base 200;

[0028] Please refer to it again. Figure 1-2Two plastic chain covers 110 are slidably connected to the top of the track body 100. A positioning frame 120 is fixedly connected to the bottom of the inner cavity of the track body 100. An installation chamber 130 is slidably connected to the bottom of the inner cavity of the positioning frame 120. Two gear driven screws 140 are rotatably connected to the inner wall of the installation chamber 130. One end of the gear driven screw 140 extends into the interior of the installation chamber 130. A threaded sleeve 141 is screwed onto the outer side of the gear driven screw 140. A positioning plate 150 is fixedly connected to one end of the threaded sleeve 141. The positioning plate 150 engages with the positioning frame 120. A gear drive rod 160 is rotatably connected to one side of the installation chamber 130. One end of the gear drive rod 160 passes through the installation chamber 130 and extends into the installation chamber 130. The inner cavity is formed, and one end of the gear drive rod 160 is meshed with the gear driven screw 140. By sliding the installation chamber 130 into the positioning frame 120, the gear drive rod 160 is rotated to drive the gear driven screw 140 meshing with it to rotate. The threaded sleeve 141 installed on the gear driven screw 140 moves with the rotation of the gear driven screw 140, and the positioning plate 150 installed on the threaded sleeve 141 moves to contact and engage with the positioning frame 120, thereby fixing the position of the installation chamber 130 and fixing the load-bearing guide rail 260 above the installation chamber 130. The installation chamber 130 can be disassembled by reversing the gear drive rod 160.

[0029] In summary, the installation and disassembly of the load-bearing guide rail 260 can be completed quickly and conveniently.

[0030] Please refer to it again. Figure 1-4The mounting base 200 is located inside the track body 100. A base plate 210 is fixedly connected to the bottom of the inner cavity of the mounting base 200, and the base plates 210 are evenly distributed sequentially. A rubber seat 220 is fixedly connected to the top of the base plate 210. A friction rod 221 is fixedly connected to the top of the rubber seat 220, and the friction rods 221 are evenly distributed sequentially. A rubber plate 230 is slidably connected to the outer side of the friction rod 221. A friction sleeve 231 is fixedly connected to the top of the rubber plate 230, and the friction sleeves 231 are evenly distributed sequentially. The inner side of the friction sleeve 231 contacts the friction rod 221. Repulsive magnets 240 are fixedly connected to the top of the base plate 210 and the bottom of the rubber plate 230. The top of the rubber plate 230 is fixedly... A connecting rod 250 is fixedly connected to the bottom of the connecting rod 250, and a load-bearing guide rail 260 is fixedly connected to the top of the connecting rod 250. When the load-bearing guide rail 260 is under pressure, it applies pressure to the connecting rod 250 at the bottom, causing the rubber plate 230 to descend. This causes the friction sleeve 231 on the descending plate to rub against the friction rod 221, generating damping. At the same time, as the rubber plate 230 descends, the repulsive magnet 240 on the rubber plate 230 comes close to the repulsive magnet 240 installed on the base plate 210, generating a repulsive force. This prevents the load-bearing guide rail 260 from being pressed, which could cause the bottom structure to collide and generate noise. Furthermore, when the rubber plate 230 descends to the bottom, it comes into contact with the rubber seat 220 and is squeezed, further preventing noise generation.

[0031] In summary, this can effectively reduce the noise generated during the operation of the load-bearing guide rail 260;

[0032] In practical use, those skilled in the art slide the mounting chamber 130 into the positioning frame 120, then rotate the gear drive rod 160 to drive the gear driven screw 140 meshing with it to rotate. This causes the threaded sleeve 141 mounted on the gear driven screw 140 to move along with the rotation of the gear driven screw 140, causing the positioning plate 150 mounted on the threaded sleeve 141 to move and contact the positioning frame 120, thus fixing the position of the mounting chamber 130 and fixing the load-bearing guide rail 260 above the mounting chamber 130. When disassembling the mounting chamber 130, [the following steps are taken]. The load-bearing guide rail 260 is driven by the reverse gear 160. When the load-bearing guide rail 260 is under pressure, pressure is applied to the connecting rod 250 at the bottom, causing the rubber plate 230 to descend. This causes the friction sleeve 231 on the descending plate to rub against the friction rod 221, generating damping. At the same time, as the rubber plate 230 descends, the repulsive magnet 240 on the rubber plate 230 comes closer to the repulsive magnet 240 installed on the base plate 210, generating a repulsive force. This prevents the load-bearing guide rail 260 from being pressed, which could cause the bottom structure to collide and generate noise. Furthermore, when the rubber plate 230 descends to the bottom, it comes into contact with the rubber seat 220 and is squeezed, further preventing noise.
