Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying equipment, and more specifically, to a double-layer conveyor line lifting mechanism. Background Technology
[0002] As production scale expands and processes become more complex, single conveyor lines often fall short of actual production needs, leading to the development of double-layer or even multi-layer conveyor systems. Double-layer conveyor systems can make full use of space, increase cargo transport capacity, and improve site utilization, but they also present challenges in transferring goods between conveyor lines at different heights.
[0003] Currently, existing cargo transfer methods have many shortcomings. On the one hand, traditional transfer equipment has a complex structure, usually requiring a large number of mechanical parts and complex transmission systems. This not only increases the manufacturing cost and maintenance difficulty of the equipment, but also easily leads to frequent equipment failures, affecting the continuity of production. For example, some lifting mechanisms use chain or belt drives, which are prone to wear and breakage during long-term use, requiring regular replacement and maintenance, thus increasing the operating costs of enterprises.
[0004] On the other hand, existing transfer equipment suffers from poor stability and accuracy during cargo transfer. During cargo lifting, the lack of effective guiding and securing devices makes goods prone to swaying, tilting, or even slipping, which can damage the goods and pose safety hazards to operators. Furthermore, when transferring goods from the lifting platform to the upper conveyor line, the lack of precise positioning and pushing devices often prevents goods from being accurately placed on the conveyor line, leading to jams and accumulations during transport and impacting efficiency.
[0005] Therefore, this application provides a double-layer conveyor lifting mechanism to solve the problems mentioned in the background art. Utility Model Content
[0006] 1. Technical problems to be solved
[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a double-layer conveyor line lifting mechanism, which can realize the transfer of goods conveyed by the double-layer conveyor line, thereby improving the transfer efficiency of goods.
[0008] 2. Technical Solution
[0009] To solve the above problems, the present invention adopts the following technical solution.
[0010] A double-layer conveyor line lifting mechanism includes a first conveyor belt, a second conveyor belt connected to the upper end of the first conveyor belt, a main frame connected to the left end of the first conveyor belt, a lead screw installed inside the main frame, a drive box installed at the upper end of the main frame, a servo motor installed inside the drive box, a helical gear connected to the output end of the servo motor and the upper end of the lead screw, the two helical gears meshing with each other, a lifting plate provided at the outer end of the lead screw, a movable block fixedly connected to the outer end of the lifting plate, the movable block located outside the lead screw and threadedly connected to the lead screw, a U-shaped connecting plate fixedly connected to the outer end of the main frame, a pushing plate provided inside the U-shaped connecting plate, and an electric push rod installed between the pushing plate and the U-shaped connecting plate, which can realize the transfer of goods conveyed by the double-layer conveyor line, thereby improving the transfer efficiency of goods;
[0011] As a further improvement of this utility model: a guide rod is connected between the upper and lower inner walls of the main frame, and a guide slider is connected to the outer end of the lifting plate. The guide slider is located outside the guide rod and is slidably connected to the guide rod. By setting the guide rod and the guide slider, the lifting plate can be made more stable when sliding upward, thereby improving the stability of the entire device.
[0012] As a further improvement of this utility model: a distance sensor is installed on the inner wall of the main frame. The distance sensor is connected to the electric push rod. By setting the distance sensor, the distance between the goods and the distance sensor can be detected and fed back to the electric push rod to control the extension of the electric push rod so that the push plate pushes the goods onto the second conveyor belt.
[0013] As a further improvement of this utility model, the upper end of the drive box is provided with a plurality of evenly distributed heat dissipation holes. By providing heat dissipation holes, the heat generated inside the drive box can be dissipated in a timely manner during long-term operation.
[0014] As a further embodiment of this utility model: a rotating groove is carved into the inner wall of the main frame, and the lead screw is located in the rotating groove and rotatably connected to the rotating groove. By setting the rotating groove, the lead screw and the main frame can rotate, thereby driving the movable block upward or downward through the rotation of the lead screw, realizing the lifting of the goods and the lowering of the lifting plate.
[0015] As a further improvement of this utility model, the upper end of the lifting plate is fixedly connected with a plurality of evenly distributed anti-slip strips.

[0016] 3. Beneficial effects
[0017] Compared with existing technologies, the advantages of this utility model are:
[0018] 1. This device uses a screw drive to move the lifting plate up and down, enabling rapid lifting of goods. At the same time, the guide rod and guide slider ensure the lifting plate remains stable during the ascent, preventing swaying and tilting, thus ensuring the safety of the goods. The combination of the distance sensor and the electric push rod can precisely control the push plate to push the goods to the second conveyor belt, greatly improving the efficiency of goods transfer between conveyor lines at different heights and ensuring the smooth operation of the entire production or logistics process.
[0019] 2. The anti-slip strips evenly distributed on the lifting plate of this device increase the friction between the goods and the lifting plate, effectively preventing the goods from sliding during the lifting process and improving the safety of goods transportation. Moreover, the lifting mechanism has a simple structure and can be appropriately adjusted according to goods of different specifications, shapes and weights. It has strong versatility and flexibility, which can meet the diverse cargo transfer needs of enterprises and reduce the procurement and use costs of enterprises.
[0020] 3.

[0029] Example:
[0030] Please see Figures 1-3 A double-layer conveyor line lifting mechanism includes a first conveyor belt 1, a second conveyor belt 2 connected to the upper end of the first conveyor belt 1, a main frame 3 connected to the left end of the first conveyor belt 1, a lead screw 4 installed inside the main frame 3, a drive box 5 installed at the upper end of the main frame 3, a servo motor 6 installed inside the drive box 5, a helical gear 7 connected to the output end of the servo motor 6 and the upper end of the lead screw 4, the two helical gears 7 meshing with each other, a lifting plate 8 provided at the outer end of the lead screw 4, a movable block 9 fixedly connected to the outer end of the lifting plate 8, the movable block 9 being located outside the lead screw 4 and threadedly connected to the lead screw 4, a U-shaped connecting plate 10 fixedly connected to the outer end of the main frame 3, a pushing plate 11 provided inside the U-shaped connecting plate 10, and an electric push rod 12 installed between the pushing plate 11 and the U-shaped connecting plate 10, which can realize the transfer of goods conveyed by the double-layer conveyor line, thereby improving the transfer efficiency of goods;
[0031] Please see Figures 1-2A guide rod 301 is connected between the upper and lower inner walls of the main frame 3. A guide slider 801 is connected to the outer end of the lifting plate 8. The guide slider 801 is located outside the guide rod 301 and is slidably connected to the guide rod 301. By setting the guide rod 301 and the guide slider 801, the lifting plate 8 can be made more stable when sliding upward, thereby improving the stability of the entire equipment. A distance sensor 302 is installed on the upper inner wall of the main frame 3. The distance sensor 302 is connected to the electric push rod 12. By setting the distance sensor 302, it can detect the distance between the goods and the distance sensor 302 and send a signal to the electric push rod 12 to control the extension of the electric push rod 12 to cause the extrusion plate 11 to push the goods onto the second conveyor belt 2.
[0032] Please see Figures 1-3 The drive box 5 has multiple evenly distributed heat dissipation holes 501 at its upper end. By setting the heat dissipation holes 501, the drive box 5 can dissipate the heat generated inside in a timely manner during long-term operation. The inner wall of the main frame 3 has a rotating groove 303. The lead screw 4 is located in the rotating groove 303 and is rotatably connected to the rotating groove 303. By setting the rotating groove 303, the lead screw 4 can rotate with the main frame 3. Thus, the rotation of the lead screw 4 can drive the movable block 9 up or down, thereby lifting the goods and lowering the lifting plate 8. Multiple evenly distributed anti-slip strips 802 are fixedly connected to the upper end of the lifting plate 8. By setting the anti-slip strips 802, the friction between the goods and the lifting plate 8 can be increased, preventing the goods from sliding during the lifting process.
[0033] Working principle: When this utility model is working, the output end of the drive box 5 rotates, and with the meshing action between the two helical gears 7, the lead screw 4 can be rotated, thereby driving the movable block 9 to move upward, thus causing the lifting plate 8 and the goods on it to move upward. When it reaches the level with the second conveyor belt 2, the electric push rod 12 is driven to move the extrusion plate 11 towards the lifting plate 8, thereby causing the extrusion plate 11 to push the goods onto the second conveyor belt 2, completing the lifting of the goods. Compared with the prior art, this utility model can realize the transfer of goods in the double-layer conveyor line, thereby improving the transfer efficiency of goods.
[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto.
