Technical Field

[0001] This utility model belongs to the field of lifting platform technology, specifically relating to a screw lifting and stacking mechanism. Background Technology

[0002] Currently, the material receiving lifting platform in the corrugated shearing unit industry uses a hydraulic single-source cylinder to achieve the up and down movement of the material receiving platform. The hydraulic single source and cylinder are installed under the platform, which is in a small space, inconvenient for maintenance, and expensive to manufacture. Long-term use may lead to the risk of cylinder explosion.

[0003] In view of this, the present invention provides a screw-driven stacking mechanism as an optional solution for realizing a lifting platform. Utility Model Content

[0027] 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.

[0028] Example 1:

[0029] This utility model relates to a screw-driven stacking mechanism, such as... Figures 1-2 As shown, it includes a lifting platform 2 and a lifting mechanism 1 disposed on one side of the lifting platform 2 for driving the lifting platform 2 to rise and fall.

[0030] The lifting mechanism 1 includes a support component 11 and a drive mechanism 12 mounted on the support component 11; the lifting platform 2 includes a base 21 and a working platform 23 movably connected to the base 21. The working platform 23 is connected and fixed to a movable component 112 movably connected to the output end of the drive mechanism 12. The movable component 112 is configured to move horizontally in the longitudinal direction when the output end of the drive mechanism 12 is running, so as to drive the working platform 23 to rise and fall.

[0031] Specifically, such as Figure 3As shown, the drive mechanism 12 includes a circumferential drive component 121 and a lead screw 122 connected to the movable end of the circumferential drive component 121. The lead screw 122 is longitudinally threaded through and connected to the movable component 112. The support assembly 11 includes support walls 111 disposed opposite to each other, and a top wall 114 and a bottom wall 115 connected opposite to each other between the support walls 111. The circumferential drive component 121 is mounted on the bottom wall 115. In this embodiment, the circumferential drive component 121 is a geared drive motor combining a reducer and a servo motor. It is electrically connected to an external power supply through a controller so that its movable end can be driven to rotate forward and backward by the controller, thereby driving the lead screw 122 to rotate along its axial direction, thereby causing the movable component 112 to rise and fall.

[0032] Furthermore, a guide post 113, which is arranged in the same direction as the extension direction of the lead screw 122, is connected between the top wall 114 and the bottom wall 115. The guide post 113 slides through the movable part 112. In this embodiment, the guide posts 113 are symmetrically arranged, and they pass through the sliding sleeve seat and slide to connect with the movable part 112, so that the movable part 112 can be raised and lowered smoothly through the cooperation between the guide post 113 and the sliding sleeve seat.

[0033] Furthermore, such as Figures 3-4 As shown, the lifting platform 2 is a common scissor lift platform. Its working platform 23 is movably connected to the base 21 through at least one set of scissor arms 22 set between it and the base 21, so as to realize the horizontal lifting of the working platform 23.

[0034] Specifically, the scissor boom 22 includes a first cross arm 221 and a second cross arm 222 rotatably connected together; the two ends of the first cross arm 221 are rotatably connected to the work platform 23 and slidably connected to the base 21, respectively; the two ends of the second cross arm 222 are slidably connected to the work platform 23 and rotatably connected to the base 21, respectively. In this embodiment, the movable component 112 is fixedly connected to the side edge of the work platform 23. When the movable component 112 is raised and lowered by the drive mechanism 12, the first cross arm 221 and the second cross arm 222 rotate relative to each other, thereby driving the work platform 23 to move horizontally.

[0035] Furthermore, to better facilitate relative rotation between the first crossarm 221 and the second crossarm 222 and reduce driving force loss, rollers 223 are rotatably connected to one end of both the first crossarm 221 and the second crossarm 222. The first crossarm 221 and the second crossarm 222 are slidably connected to the base 21 and the work platform 23 respectively via the rollers 223. The rollers reduce sliding friction, allowing the work platform 23 to be raised and lowered with less driving force.

[0036] In another preferred embodiment, based on the above technical solution, it is conceivable to those skilled in the art that: the lifting mechanism 1 can be arranged on both sides of the lifting platform 2, and the lifting mechanism 1 on both sides can simultaneously drive the working platform 23 to rise and fall, thereby improving the overall stability of the working platform 23.

[0037] Example 2:

[0038] Figures 3-4 This illustrates a second embodiment of the present invention, which differs from the first embodiment described above in that the work platform 23 is configured as a conveying device, such as a common conveyor belt. This allows materials placed on the work platform 23 to be automatically removed.

[0039] Specifically, the conveying device includes a support frame 231, a second circumferential drive component 232 mounted on the support frame 231, at least two sets of conveying rollers 233 rotatably connected to the support frame 231, a sprocket 234 axially connected to the end of the conveying rollers 233, and a chain 235 chain-driven to the sprocket 234; at least one set of sprockets 234 is axially connected to the output end of the second circumferential drive component 232.

[0040] In this embodiment, the second circumferential drive component 232 is structurally configured with the first circumferential drive component 121. The second circumferential drive component 232 is axially connected to the sprocket 234, which can drive the sprocket 234 to rotate. Under the action of the chain 235, the parallel conveying rollers 233 on the support frame 231 are driven to rotate synchronously and in the same direction, so that the materials placed on them can be automatically conveyed out, thereby effectively reducing manual labor and improving the degree of automation.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
