Abstract

[0001] This utility model belongs to the field of pneumatic lifting door technology, and relates to an automatic lifting door mechanism and an automatic lifting door. Background Technology
[0002] A temperature control machine uses an automated AGV (Automated Guided Vehicle) for material feeding during its production process, requiring multiple opening and closing of the machine door. Current technology primarily employs manually operated hinged doors. While this type of door is relatively simple in design, when it needs to be moved down from above the machine for closure, the operator must manually push the door forward until it is flush against the frame. This method is not only inefficient and increases the complexity of manual operation, but also, in emergency situations, may disrupt the normal operation of the production line due to delayed action.
[0003] Therefore, in response to these problems with existing technologies, there is an urgent need to invent a new structure to enable automatic doors to move automatically in two directions, namely up and down and forward and backward; to achieve highly efficient automated control capabilities and minimize the occupation of on-site space, so as to adapt to the rapid development and changes of automated production lines.

[0034] An automatic lifting door mechanism, such as Figure 1-6 As shown, the system includes a base plate 1, a first cam bearing 2, a second cam bearing 3, a connecting block 4, and a moving mechanism 5. The base plate 1 is an L-shaped plate, and a first track 11, which is a J-shaped track, is provided on the outer side of the vertical surface of the base plate 1. A second track 41 is provided on the connecting block 4, and the second track 41 is perpendicular to the first track 11. The first cam bearing 2 is provided inside the first track 11 and slides within the first track 11. The first cam bearing 2 is connected to the door body 7. The second cam bearing 3 is provided inside the second track 41 and slides within the second track 41. The second cam bearing 3 is connected to the door body 7. The sliding directions of the first cam bearing 2 and the second cam bearing 3 are perpendicular. The moving mechanism 5 is provided on the inner side of the base plate 1, and the connecting block 4 is provided on the top surface of the vertical surface of the base plate 1. The connecting block 4 is connected to the moving mechanism 5.
[0035] Specifically, such as Figure 1 and 4As shown, in an automatic lifting door mechanism, the first cam bearing 2 and the second cam bearing 3 are connected to the door body 7 via different fasteners, which can be flexibly set according to the size and material of the door body 7. In this automatic lifting door mechanism, a moving mechanism 5 provides the moving power to the door body 7. The moving mechanism 5 drives the connecting block 4 to move up and down, and the connecting block 4 drives the door body 7 to move up and down via the second cam bearing 3. When the connecting block 4 moves downward, the first cam bearing 2 moves downward within the first track 11; when the first cam bearing 2 reaches the lowest point of the first track 11, since the first track 11 is J-shaped, the first cam bearing 2 moves inward towards the door body 7 due to inertia, and the second cam bearing 3 shifts within the second track 41, causing the door body 7 to slide forward and complete the closing action. The base plate 1 has an L-shaped cross-section, with the connecting block 4 installed on the vertical surface and the moving structure installed on the inner side of the parallel surface. The door body 7 moves up and down along the side length of the vertical surface of the base plate 1. The first track 11 is a groove structure set in the base plate 1, and the second track 41 is a groove structure set in the connecting block 4. The cam bearing, which slides easily within the track, features rolling elements designed to withstand large radial and axial loads, ensuring stable operation even under heavy loads. The cam bearing typically incorporates lubrication channels and sealing structures to reduce friction and prevent contaminant intrusion, thereby improving service life and reliability, making it suitable for stable operation under harsh conditions.
[0036] An automatic lifting door mechanism employs a J-shaped track as the guide for the movement of the door body 7. The cooperation of the moving mechanism 5 and the connecting block 4 allows for automated forward / backward and up / down movement of the door body 7 with power in one direction, minimizing space occupation, effectively avoiding interference with the production line layout, and ensuring unaffected production efficiency. This automatic lifting door features a simplified structure, stable operation, and broad application prospects and practical value.
[0037] like Figure 3-6 As shown, in this embodiment, the moving mechanism 5 includes a linear guide rail 51, a rodless cylinder 52, a slider 53, a first connecting plate 54, and a second connecting plate 55; the rodless cylinder 52 is provided on the inner side of the parallel surface of the base plate 1, and the rodless cylinder 52 is connected to the second connecting plate 55; the linear guide rail 51 is provided on the inner side of the vertical surface of the base plate 1, and the slider 53 is provided on the linear guide rail 51; the first connecting plate 54 is connected to the slider 53, and the slider 53 moves on the linear guide rail 51; the connecting block 4 is connected to the slider 53 through the first connecting plate 54, and the second connecting plate 55 is connected to the slider 53 through the first connecting plate 54.
[0038] Specifically, the rodless cylinder 52 refers to a cylinder that uses a piston to directly or indirectly connect to an external actuator, causing it to reciprocate. The rodless cylinder 52 has the advantage of saving installation space. Driven by the rodless cylinder 52, the connecting block 4 moves up and down along the linear guide rail 51 via the first connecting plate 54 and the second connecting plate 55. The first cam bearing 2 and the second cam bearing 3 are mounted on the door body 7. When the first cam bearing 2 moves to the lowest point of the first track 11 and needs to move back and forth, the second cam bearing 3 is guided by the back and forth direction of the first track 11, causing the door body 7 to move back and forth accordingly, ultimately closing the automatic door. The opening principle is the same. Using a single power system, the rodless cylinder 52, two-directional movement is achieved. This simplifies the action mechanism and significantly reduces the size and manufacturing cost of the mechanism.
[0039] like Figure 3 As shown, in this embodiment, a limiting mechanism 6 is also included, with limiting mechanisms 6 provided at both ends of the linear guide rail 51. The limiting mechanism 6 is a nitrogen spring.
[0040] Specifically, the limiting mechanism 6 effectively restricts the movement distance of the first moving part, improving safety. The nitrogen spring, acting as the limiting mechanism 6, can generate a large elastic force within a small volume, providing an effective deceleration effect for the moving part.
[0041] like Figure 4 and 5 As shown, in this embodiment, two first tracks 11 are provided on the outer side of the vertical plane of the substrate 1, and two first cam bearings 2 are respectively connected to the two top corners on one side of the door body 7.
[0042] Specifically, the first cam bearing 2 is located at the top corner of the door body 7, and is equipped with a first track 11. The arrangement of two first tracks 11 and two first cam bearings 2 further improves the smoothness and stability of the door body 7 movement.
[0043] like Figure 2 and 3 As shown, in this embodiment, there are two sliders 53, located at both ends of the first connecting plate 54.
[0044] Specifically, the first connecting plate 54 transmits kinetic energy through two sliders 53, further improving the smoothness and stability of the door 7's movement.
[0045] An automatic lifting door, such as Figure 7 and 8 As shown, it includes a door body 7 and two automatic lifting door mechanisms as described above, with automatic lifting door mechanisms connected to opposite sides of the door body 7.
[0046] Specifically, automatic lifting door mechanisms are connected to both sides of the door body 7. The two automatic lifting door mechanisms operate synchronously. Since an automatic lifting door mechanism has the above-mentioned technical effects, an automatic lifting door including an automatic lifting door mechanism should also have the corresponding technical effects, which will not be elaborated here.
[0047] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
