Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, and in particular relates to a door panel feeding mechanism. Background Technology

[0002] The existing door panel processing requires manual transport of stacked door panels to the loading area, and then manual lifting of the door panels onto the processing table. The whole process is time-consuming and labor-intensive, and the transport trolley cannot complete both the transport and lifting actions.

[0003] Chinese patent CN214053446U discloses a feeding device for a door panel forming machine. The feeding trolley can transport door panels, and the feeding trolley is slidably connected to a lifting frame via a cylinder. The lifting frame is driven by the cylinder to complete the feeding of the door panels.

[0004] However, the above solution still has some shortcomings:

[0005] 1. It is difficult for the loading trolley to maintain a straight line during transportation and movement. The position of the loading trolley and the loading platform are prone to deviation, so the position of the loading trolley needs to be adjusted after it moves to one side of the loading platform to ensure that the door panel is aligned with the loading platform.

[0006] 2. The door panels are placed directly on the lifting frame. The impact generated by the stacking of door panels can easily damage the cylinder piston rod. The loading vehicle lacks a buffer protection structure when placing door panels. Utility Model Content

[0007] The purpose of this utility model is to provide a door panel loading mechanism to solve the problems existing in the background art.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] A door panel loading mechanism includes a lifting trolley and a slide rail located at the bottom of the lifting trolley. The lifting trolley includes an outer frame and an inner frame located within the outer frame, a worm gear lifting assembly, and a support frame. The base of the worm gear lifting assembly is fixed at the four corners of the inner frame. The four lifting ends of the worm gear lifting assembly are respectively connected to the support frame. The support frame is connected to the outer frame through guide columns. The bottom of the inner frame is suspended. The outer frame is provided with casters corresponding to the positions of the slide rails.

[0010] Furthermore, the outer frame includes a first connecting frame and a first lifting frame located on both sides of the first connecting frame, wherein the highest point of the first connecting frame is lower than the highest point of the first lifting frame.

[0011] Furthermore, the support frame includes a second connecting frame and second lifting frames located on both sides of the second connecting frame. The highest point of the second connecting frame is lower than the highest point of the second lifting frame. The second connecting frame rests on the first connecting frame, and the highest point of the second lifting frame is lower than the highest point of the first lifting frame.

[0012] Furthermore, the guide post is located above the slide rail, with its bottom suspended from the slide rail. One end of the guide post is fixedly connected to the second connecting frame, and the other end of the guide post passes through the first connecting frame and is slidably connected to it.

[0013] Furthermore, a placement frame is fixed to the top of the first lifting frame, and the door panel is located on the placement frame.

[0014] Furthermore, the caster has a V-shaped wheel surface and is engaged with the slide rail.

[0015] Furthermore, limiting plates are provided at both ends of the slide rail.

[0016] The beneficial effects of this utility model are:

[0017] 1) The door panel is supported and transported by the outer frame. The inner frame, worm gear lifting assembly and support frame are not subjected to the pressure of the door panel. This ensures that the impact force generated during loading will not affect the worm gear lifting assembly. At the same time, the bottom of the inner frame is suspended, which makes it convenient for the outer frame to transport the door panel.

[0018] 2) By having the inner frame abut against the ground, the door panel can be supported, ensuring that it will not shift during the lifting process. At the same time, it does not require the outer frame to be lifted and moved. The outer frame is kept in place by the casters and slide rails to prevent the outer frame from shifting after lifting.

Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] See Figures 1-5 This utility model provides a technical solution:

[0027] like Figures 1-5 As shown, a door panel loading mechanism includes a lifting trolley 2 and a slide rail 1 located at the bottom of the lifting trolley 2. The lifting trolley 2 includes an outer frame 3 and an inner frame 4 located within the outer frame 3, a worm gear lifting assembly 6, and a support frame 5. The base of the worm gear lifting assembly is fixed at the four corners of the inner frame 4. The four lifting ends of the worm gear lifting assembly are respectively connected to the support frame 5. The support frame 5 is connected to the outer frame 3 through guide columns 7. The bottom of the inner frame 4 is suspended. The outer frame 3 is provided with casters 8 at positions corresponding to the slide rail 1.

[0028] Furthermore, the outer frame 3 includes a first connecting frame 31 and a first lifting frame 32 located on both sides of the first connecting frame 31, wherein the highest point of the first connecting frame 31 is lower than the highest point of the first lifting frame 32.

[0029] Furthermore, the support frame 5 includes a second connecting frame 51 and a second lifting frame 52 located on both sides of the second connecting frame 51. The highest point of the second connecting frame 51 is lower than the highest point of the second lifting frame 52. The second connecting frame 51 rests on the first connecting frame 31, and the highest point of the second lifting frame 52 is lower than the highest point of the first lifting frame 32.

[0030] Furthermore, the guide post 7 is located above the slide rail 1, the bottom of the guide post 7 is suspended from the slide rail 1, one end of the guide post 7 is fixedly connected to the second connecting frame 51, and the other end of the guide post 7 passes through the first connecting frame 31 and is slidably connected to the first connecting frame 31.

[0031] With the above technical solution, the two ends of the slide rail 1 are located between two work areas, one being the unloading area and the other the loading area. The lifting trolley 2 can move linearly along the slide rail 1 for convenient transport between the two areas. The lifting trolley 2 loads the door panel 9 in the unloading area, and moves along the slide rail 1 to the loading area via casters 8. The casters 8 have V-shaped wheel surfaces and engage with the slide rail 1 to ensure that the lifting trolley 2 does not detach from the slide rail 1 during the movement.

[0032] At this time, the door panel 9 is pressed on the outer frame 3. Specifically, the door panel 9 is on the first lifting frame 32 at the highest point. The outer frame 3 supports and transports the door panel 9. The inner frame 4, the worm gear lifting assembly, and the support frame 5 are not subjected to the pressure of the door panel 9, which can ensure that the impact force generated during loading will not affect the worm gear lifting assembly 6. At the same time, the bottom of the inner frame 4 is suspended, which can facilitate the outer frame 3 to transport the door panel 9.

[0033] When the lifting trolley 2 moves to the loading area, the casters 8 of the lifting trolley 2 stop after contacting the limit plates 11 at both ends of the slide rail 1. At this time, the door panel 9 is transported to the appropriate position in the loading area, which is convenient for the door panel 9 to be lifted and transferred later.

[0034] When the worm gear lifting assembly 6 is activated, its base is fixed to the four corners of the inner frame 4, and its four lifting ends are connected to the support frame 5. The support frame 5 is slidably connected to the outer frame 3 via guide posts 7. At this time, the worm gear lifting assembly will lift the support frame 5. Since the highest point of the second lifting frame 52 is lower than the highest point of the first lifting frame 32, as the worm gear lifting assembly 6 operates, the second lifting frame 52 will exceed the first lifting frame 32 until it abuts against the bottom of the door panel 9. When the door panel 9 is pressed against the second lifting frame 52, the bottom of the inner frame 4 abuts against the ground, completing support. The worm gear lifting assembly 6 then drives the second lifting frame 52 to lift the door panel 9 to the loading platform. At this time, the outer frame 3 is not subjected to pressure from the door panel 9.

[0035] By having the inner frame 4 abut against the ground, it can support the door panel 9 and ensure that it will not shift during the lifting process. At the same time, it does not require the outer frame 3 to be lifted and moved. The outer frame 3 is kept in contact with the slide rail 1 via the casters 8 to prevent the outer frame 3 from shifting after lifting.

[0036] Furthermore, a placement frame 33 is fixed to the top of the first lifting frame 32, and the door panel 9 is located on the placement frame 33. The placement frame 33 increases the support area for the door panel 9, making it easier for the door panel 9 to be placed stably and not to shift during the movement of the lifting trolley 2.

[0037] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
