Description

Technical Field

[0001] This utility model relates to the field of treadmill production line technology, specifically to an automatic lifting and palletizing mechanism for treadmill production lines. Background Technology

[0002] After the treadmills are packaged on the production line, the packaging boxes need to be stacked and placed by a palletizing mechanism, and then transported together by a transport device.

[0003] For example, Chinese patent CN222006603U discloses a packaging box palletizing robot, including a base plate; a first drive assembly is mounted on the base plate, a counterweight assembly is mounted on the first drive assembly, a second drive assembly is mounted on the counterweight assembly, and a clamping assembly is mounted on the second drive assembly. The clamping assembly includes a sliding frame, an L-shaped clamping plate is mounted under the first fixing bar, push plates are slidably mounted on two second limiting rods, and side clamping plates are mounted on the actuating ends of two second electric push rods. When the second electric push rod retracts, it drives the side clamping plates to slide on the second limiting rods, thereby... The side clamps push the packaging boxes onto the horizontal section of the L-shaped clamps. A counterweight is set on the L-shaped lifting frame to reduce the lifting force required during the lifting process. Compared with traditional packaging box palletizing robots, this allows for a larger lifting weight range and effectively prevents damage to the packaging boxes due to excessive clamping force. Traditional palletizing devices require gradually increasing the height as the boxes are stacked to facilitate subsequent palletizing. However, the set height position is difficult to control precisely, which can easily lead to a certain height difference, causing the palletizing to deviate and affecting subsequent transportation. Therefore, an automatic lifting palletizing mechanism for treadmill production lines is proposed to solve the above problems. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-6 The present invention provides the following technical solution: an automatic lifting and palletizing mechanism for a treadmill production line, comprising a main frame 1, wherein a slide rail 11 is fixedly installed on the inner wall of the main frame 1, and a lifting assembly is installed at the rear end of the main frame 1; In this embodiment, the lifting assembly includes a first motor 12 fixedly installed at the rear end of the main frame 1. A transmission wheel set 13 is installed at one end of the output shaft of the first motor 12. The transmission wheel set 13 includes two sets of transmission wheels and a transmission belt sleeved on the transmission wheels.

[0015] The main frame 1 has a screw 14 rotatably mounted at its rear end, and the top end of the screw 14 is fixedly connected to a transmission wheel. The lifting platform 2 has a connecting frame 21 fixedly mounted at its rear end, and the connecting frame 21 is threadedly connected to the screw 14. When the first motor 12 is started, the screw 14 is driven to rotate through the transmission wheel assembly, thereby driving the lifting platform 2 to rise and fall. In this embodiment, the lifting platform 2 is installed inside the main frame 1. The lifting platform 2 is adjusted by lifting components. A slider 22 is fixedly installed at one end of the lifting platform 2. The slider 22 matches the slide rail 11, and a limit component is provided inside the slider 22.

[0016] The limiting assembly includes a limiting rod 27 installed inside the slider 22. The outer surface of the slide rail 11 has several limiting grooves that match one end of the limiting rod 27. An electromagnet 28 is fixedly installed inside one end of the slider 22, and the electromagnet 28 is sleeved on the outer surface of one end of the limiting rod 27. A return spring 29 is sleeved on the outer surface of the limiting rod 27 on one side of the electromagnet 28. By activating the electromagnet 28, the limiting rod 27 is driven to insert into the corresponding limiting groove of the slide rail 11, thereby positioning and fixing the lifting platform 2. During the outward movement of the limiting rod 27, it will compress the return spring 29.

[0017] In this embodiment, the lifting platform 2 is internally equipped with a chain drive assembly 26, which includes a drive shaft rotatably installed inside the lifting platform 2 and chains sleeved on both ends of the drive shaft. A second motor 25 is fixedly installed on one outer surface of the lifting platform 2, and the output shaft of the second motor 25 is fixedly connected to one end of the drive shaft. A mounting plate 23 is fixedly installed on the top of the lifting platform 2, and a push plate 24 is provided on the top of the mounting plate 23. A through groove is opened on the outer surface of the mounting plate 23, and the bottom end of the push plate 24 passes through the through groove and is fixedly connected to the outer surface of the chain. When the second motor 25 is started, the push plate 24 is driven outward by the chain on the chain drive assembly 26 to push the packaging box.

[0018] The working principle of this embodiment is as follows: During palletizing, the treadmill packaging box is pushed from one side of the main frame 1 to the mounting plate 23 of the lifting platform 2 by the conveying system. Then, the first motor 12 is started, which drives the screw 14 to rotate through the transmission wheel assembly. The connecting frame 21 at one end of the lifting platform 2 is threadedly connected to the screw 14, thereby driving the lifting platform 2 to move up and down. During the lifting process, the slider 22 slides along the slide rail 11. When the lifting platform 2 moves to the set height, the electromagnet 28 is activated to drive the limit rod 27 to insert into the corresponding limit groove of the slide rail 11, thereby positioning and fixing the lifting platform 2. As the limit rod 27 moves outward, it will squeeze the return spring 29. Then, the second motor 25 is activated, and the chain on the chain drive assembly 26 drives the push plate 24 to push the packaging box outward. After the box is pushed out, the electromagnet 28 is turned off, and the return spring 29 will push the limit rod 27 inward to reset, releasing the limit of the lifting platform 2.
