Description

Technical field

[0001] The invention belongs to the technical field of packaging equipment, and particularly relates to a swing-type transmission assembly. [Background Technology]

[0002] In a Chinese patent application titled "A Stepping Conveyor Device" and published on April 2, 2021, and with publication number CN112591216A, a vertically directional transmission assembly for directly driving the conveyor plate 110 to rise and fall is described. This assembly transmits power in a swinging manner, belonging to the type of swinging transmission assembly. The swinging transmission assembly includes a rotating shaft 151 / 152, a support block (swing arm) 140, and a slider 130. The rotating shaft is fixedly connected to the support block, and the support block is movably connected to the slider via a pin. The slider is a fixed structure as a whole, and the top of the slider is connected to the conveyor plate in a sliding manner.

[0003] During the actual production process, component dimensions can deviate from their designed values ​​due to machining quality issues, resulting in dimensional errors. Assembly errors can also occur due to component assembly positions deviating from their designed positions. These various errors accumulate over the assembly process, causing the final product to malfunction, or even prevent components from being installed onto previously assembled components. Accumulated errors often manifest themselves negatively during assembly. The conveyor plate is a long metal piece that is susceptible to slight deformation after machining due to temperature and material influences. Deformation exceeding the allowable dimensional tolerance constitutes a dimensional error. Even when the slider is perfectly installed, these dimensional errors can still prevent the slider from properly assembling with the conveyor plate. This inability to assemble properly is exacerbated by slider installation errors. [Summary of the invention]

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a swing-type transmission assembly that can ensure that the slider and the conveying plate are correctly assembled together.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A swinging transmission assembly includes a rotating shaft and a floating swinging unit connected to the rotating shaft.

[0007] Preferably, the floating guide portion includes a limiting column protruding from the top support plane of the movable seat, and a limiting groove is provided on the floating plate to cooperate with the limiting column guide.

[0008] Preferably, the lateral limiting portion includes a top support plane of the movable seat for limiting the downward position of the floating plate and a limiting plate provided above the movable seat for limiting the upward position of the floating plate.

[0009] Preferably, the top support plane of the movable seat is rectangular, four limiting columns are provided and are located at the four corners of the top support plane of the movable seat, and the floating plate is rectangular and has limiting grooves corresponding to the four corners.

[0010] Preferably, the limiting plate includes a first limiting edge and a second limiting edge and a third limiting edge respectively vertically connected to the two ends of the first limiting edge; and / or, the limiting column is provided with a mounting hole, and the limiting plate is connected to the mounting hole by bolts.

[0011] Preferably, an oil storage tank for storing lubricating oil is provided at the bottom of the floating plate.

[0028] Reference Figure 1 and Figure 2 As shown, a swing transmission assembly includes a rotating shaft 10 and a fixed swing unit A and a floating swing unit B connected to the rotating shaft 10. The fixed swing unit A and the floating swing unit B are arranged side by side along the axial direction of the rotating shaft 10. The fixed swing unit A includes a swing arm 11 fixed to the rotating shaft and a movable seat 12 hinged to the swing arm, and a slider 13 is fixed to the movable seat 12. The floating swing unit B includes a swing arm 11 fixed to the rotating shaft and a movable seat 12 hinged to the swing arm. The movable seat 12 is provided with a floating plate 14 that can float laterally relative to each other, and the slider 13 is fixed to the floating plate 14. In order to guide and limit the floating of the floating plate 14, the movable seat 12 is provided with a floating guide portion for guiding the lateral floating of the floating plate 14 and a lateral limiting portion for lateral limiting the floating plate. Specifically, the floating guide comprises a stopper post 121 protruding from the top support plane of the movable seat. A stopper slot 141 is provided on the floating plate 14, which cooperates with the stopper post 121 to guide the relative floating of the floating plate 14. A lateral stopper comprises the top support plane of the movable seat, which limits the downward position of the floating plate 14. Furthermore, a stopper plate 15 is fixed above the movable seat 12 to limit the upward position of the floating plate. Because the floating plate can float laterally, even if the slider has installation errors, the slider floats with the floating plate. The lateral floating of the floating plate 14 accommodates these errors, ensuring proper assembly of the slider and conveyor plate.

[0029] In this embodiment, the top support plane of the movable seat is rectangular, and the limiting posts 121 are rectangular. Four limiting posts 121 are provided and located at the four corners of the top support plane of the movable seat. The floating plate 14 is rectangular, and rectangular limiting slots are provided at the four corners. It is understood that the relative positions of the limiting posts and limiting slots on the movable seat and floating plate can be interchanged, and the specific forms of the limiting posts and limiting slots are not limited to those in this embodiment. The number, shape, and position of the limiting posts 121 and limiting slots 141 can be varied.

[0030] In this embodiment, the limiting plate 15 is roughly U-shaped and has three limiting edges 151, specifically a first limiting edge and second and third limiting edges perpendicularly connected to the ends of the first limiting edge. The internal space enclosed by the limiting edges is used to secure the bottom of the slider to the floating plate. The three limiting edges 151 cooperate with the floating plate 14 to limit the position. The limiting column is provided with mounting holes, and the limiting plate is provided with fixing holes at both ends of the limiting edges 151. The fixing holes are connected to the mounting holes via bolts. It is understood that the limiting plate 15 can also be a rectangular frame structure.

[0031] During the transmission process of the swing transmission assembly, the floating plate will rub against the top support plane of the movable seat. In order to reduce the friction, Figure 3 As shown, the bottom of the floating plate 14 is provided with an oil reservoir 142 for storing lubricating oil. Lubricating oil is first injected into the reservoir before assembly. During operation, the lubricating oil released from the reservoir 142 provides lubrication. Furthermore, the reservoir 142 is connected to an oil filling slot 143, which is connected to the side of the floating plate for injecting lubricating oil. In the event of a lack of lubricating oil in the reservoir, the reservoir can be replenished through the oil filling slot 143.

[0032] In order to install the slider, a threaded hole is provided on the bottom surface of the slider 13, and a fixing hole is provided on the floating plate 14 corresponding to the threaded hole. The fixing hole is connected to a fixing screw, and the fixing screw is threadedly connected to the threaded hole.

[0033] The specific structure of the existing fixed swing unit A can be referred to. The bottom of the movable seat is provided with a U-shaped groove 122. A pin is connected between the left and right side walls of the U-shaped groove. The swing arm is connected to the pin. The swing arm is fixed to the rotating shaft through a clamp.

[0034] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Those skilled in the art will understand that the invention includes, but is not limited to, the drawings and the contents described in the above specific embodiments.
