Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a transmission device. Background Technology

[0002] In automated production processes within the packaging industry, material handling is a core component, and its efficiency and stability directly impact the overall effectiveness of the production line. Currently, most common material handling devices on the market employ a unidirectional conveying method. For example, horizontal conveyor belts are used for long-distance material transport, while vertical elevators handle material handling between workstations at different heights. However, this separate transport model has significant drawbacks: the connection between horizontal and vertical transport often relies on manual transfer or the addition of complex transition structures, which not only easily leads to low material handling efficiency and positioning errors but also increases the risk of material damage during transport.

[0003] In summary, existing material handling devices in the packaging field struggle to achieve seamless integration of horizontal and vertical transport, and suffer from problems such as low transport efficiency, poor positioning accuracy, and low space utilization. There is an urgent need for a new type of transport device that can optimize the transport process, improve transport efficiency, and save workshop space. Utility Model Content

[0027] Example 1

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a conveying device is mainly used to transport materials to a designated position. It first transports the material horizontally, then lifts it vertically to transport it to a preset position. It is generally used for conveying packaging materials, especially roll materials. The conveying device includes a frame 1, on which a conveying device 2 is mounted. The conveying device 2 is connected to a conveying drive device 3.

By rotating the scissor arms around the pin, the scissor arms can be extended or retracted, thereby driving the lifting platform 41 to rise or fall smoothly. Preferably, one or more scissor arms can be provided, and the multiple scissor arms can be arranged at equal intervals. The cross scissor arm structure has good mechanical stability, which can evenly distribute the weight of the material during the lifting process, prevent the lifting platform 41 from tilting, and ensure the safety of the material during vertical transmission.

[0035] In this embodiment, the conveyor belt 21 includes a first gear 212 mounted on the conveyor shaft 23, and a second gear 213 is fixedly mounted on the frame 1. The first gear 212 and the second gear 213 are connected by the conveyor belt 211. Preferably, two conveyor belts 21 are provided. A material support plate is provided on the top of the frame 1, and the two conveyor belts 21 are arranged on both sides of the support plate and are higher than the support plate. During operation, the material is placed on the support plate and conveyed forward by the conveyor belts.

[0036] In this embodiment, the conveying drive device 3 includes a conveying drive motor 31, and the output end of the conveying drive motor 31 is provided with a drive gear 32. The drive gear 32 is connected to the conveying device 2 via a chain 33. The gear and chain drive design avoids the slippage phenomenon common in belt conveyors, which can lead to deviations in the material conveying position. The gear and chain drive ensures that the material is conveyed at a constant speed, avoiding material accumulation or misalignment caused by speed fluctuations. It enables precise linear motion control, ensuring that the material is accurately conveyed to the preset position each time.

[0037] In this embodiment, the bottom of the frame 1 is provided with support legs.

[0038] The beneficial effects of this embodiment are as follows: the conveying drive device 3 drives the conveying device 2 to convey the material to the lifting device 4, and the lifting drive device 5 drives the lifting device 4 to lift the material, thereby realizing the material is transferred from a lower horizontal direction to the lifting device 4 and lifted to a preset position by the lifting device 4. This achieves seamless connection between horizontal and vertical material conveying, significantly improving overall conveying efficiency and saving workshop floor space. The coupling 22 and conveyor belt 21 enable synchronous conveying of the two conveyor belts, maintaining consistent conveying pace and preventing tilting or deviation of the material during conveying. The gear chain drive design avoids slippage common in belt conveying, preventing deviation in material conveying position. The gear chain drive ensures that the material is conveyed at a constant speed, avoiding material accumulation or misalignment due to speed fluctuations, and enables precise linear motion control, ensuring that the material is accurately conveyed to the preset position each time. Maintaining consistent conveying pace prevents tilting or deviation of the material during conveying. The conveying device in this embodiment can achieve seamless connection of material conveying in both horizontal and vertical directions, ensuring that the material can be accurately conveyed to the preset position, significantly improving the overall conveying efficiency, and saving workshop floor space.

[0039] Example 2

[0040] The difference between this embodiment and Embodiment 1 is that, in this embodiment, two fixed bases 44 are provided. One fixed base 44 is fixedly installed on the frame 1, and the other fixed base 44 is fixedly installed on the lifting platform 41. Two sliding devices 43 are provided, one on the frame 1 and the other on the lifting platform 41. By providing fixed bases 44 and sliding devices 43 on both the frame 1 and the lifting platform 41, the material can be accurately lifted along a designated vertical line on the lifting platform 41, thus ensuring accurate material transmission to the designated position. Simultaneously, the double sliding devices and double fixed bases effectively limit the vertical swing and offset of the lifting platform. Preferably, the sliding device 43 located on the frame includes two sliding rails 432, each with a slider 4311. A support plate 4312 is fixedly installed on the two sliders 4311, and a lead screw 52 is positioned between the two sliding rails 432. The sliding device located on the lifting platform 41 is equipped with a single sliding track 432, which is preferably located in the middle of the lifting platform 41 to ensure stability during the lifting process.

[0041] In this embodiment, the upper and lower ends of the first scissor arm are movably connected to the fixed base and the support plate 4312, respectively, and the upper and lower ends of the second scissor arm are movably connected to the support plate 4312 and the fixed base, respectively.

[0042] The working principle or operation process in this implementation is as follows: First, the conveyor drive device 3 is started, which drives the conveyor belt 21 to operate. The operator places the material on the material support plate of the frame, and the conveyor belt 21 conveys the material to the lifting device 4. When the material reaches the limit device 6, the detection device 7 detects that the material has reached the preset position and transmits the signal to the control system. After receiving the signal, the control system controls the lifting drive device 5 to start, which in turn drives the lifting device 4 to lift upward. After reaching the preset height, the lifting drive device 5 drives the lifting device 4 to descend for receiving.

[0043] The beneficial effect of this embodiment is that by providing a fixed base 44 and a sliding device 43 on both the lifting platform 41 and the frame 1, the material can be accurately lifted on the lifting platform 41 along a specified vertical line, thereby ensuring that the material is accurately delivered to the specified position and effectively avoiding deviations in the material delivery process.

[0044] The advantages of this utility model are as follows: The conveying drive device drives the conveying device to transport materials to the lifting device, and the lifting drive device drives the lifting device to lift the materials, thereby realizing the transfer of materials from a lower horizontal direction to the lifting device, and then lifting them to a preset position. This achieves seamless connection between horizontal and vertical material transport, significantly improving overall conveying efficiency and saving workshop floor space.
