Description

Technical Field

[0001] This utility model belongs to the field of tobacco production technology, and in particular relates to an adjustable electric telescopic frame for production. Background Technology

[0002] In the process of tobacco planting and processing, tobacco leaf curing is one of the key steps to ensure its quality. During the tobacco curing season, tobacco leaves need to be loaded into the curing barn for drying and unloaded after drying. An adjustable electric telescopic frame is required for loading and unloading the tobacco leaves.

[0003] The loading and unloading of tobacco leaves affects the curing efficiency. Fresh leaves need to be placed in the curing room within 24 hours, and dried leaves need to be unloaded in a timely manner. However, there are many pain points at present: the aisles in the curing room are narrow, the tobacco hanging racks are layered, and the workers have to climb high to hang the tobacco, which is labor-intensive and poses safety hazards; traditional tobacco hanging racks are not adjustable, and adjustments are time-consuming; dried leaves are easily damaged when unloading; existing auxiliary equipment is inefficient, has high maintenance costs, and is difficult to extend and retract accurately.

[0004] Therefore, there is an urgent need for adjustable electric telescopic racks that can be flexibly adjusted to fit the narrow space of the baking room, in order to solve the pain points and ensure baking quality and efficiency. Summary of the Invention

[0005] This utility model provides an adjustable electric telescopic frame for production, in order to solve the problems in the prior art.

[0006] The present invention adopts the following technical solution: an adjustable electric telescopic frame for production, comprising a support base, a multi-stage electric cylinder, a support frame, an adjustment and installation structure, and a fixed placement structure. The multi-stage electric cylinder is vertically mounted on the support base, and a mounting plate is provided on the telescopic end of the multi-stage electric cylinder. A support plate is provided at the bottom of the support frame, and the support plate is detachably connected to the mounting plate. The adjustment and installation structure is horizontally mounted on the top of the support frame, and the fixed placement structure is mounted on the adjustment and installation structure.

[0007] Furthermore, the adjustment and installation structure includes a mounting frame, an adjusting bidirectional lead screw shaft, an adjusting disc, and two sliders. The mounting frame is horizontally positioned on top of the support frame, and a sliding groove is provided inside the mounting frame. The adjusting bidirectional lead screw shaft is rotatably connected inside the mounting frame, and the adjusting disc is fixed to the end of the adjusting bidirectional lead screw shaft. The two sliders are symmetrically slidably connected inside the sliding groove, and the two sliders are threadedly connected to the adjusting bidirectional lead screw shaft.

[0008] Furthermore, the fixed placement structure includes two mounting components respectively disposed on the two sliders. Each mounting component includes a mounting base plate, a cover plate, and a locking screw. The end of the mounting base plate is mounted on the slider, and one end of the cover plate is hinged to the mounting base plate. The locking screw is threaded onto the cover plate for connection with the mounting base plate. Both the mounting base plate and the cover plate are provided with several corresponding mounting semicircular grooves.

[0009] Furthermore, the mounting plate and the support plate are connected by four bolts.

[0010] Furthermore, the multi-stage electric cylinder is provided with a mounting plate at its bottom, and a rotary bearing is provided at the bottom of the mounting plate. The mounting plate is rotatably connected to the top of the support base through the rotary bearing.

[0011] Furthermore, the bottom of the support base is provided with four pulleys.

[0012] Furthermore, the support base is equipped with a lithium battery that powers the multi-stage electric cylinder, and the side wall of the support base is equipped with a switch that connects to the multi-stage electric cylinder.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects: Firstly, the rotating adjustment disc of this invention drives the adjusting bidirectional lead screw shaft within the mounting frame to rotate. Because the two sliders are threadedly connected to the adjusting bidirectional lead screw shaft and slide symmetrically within the groove, when the lead screw shaft rotates, the two sliders move in opposite directions along the groove, thereby driving the fixed placement structure mounted on the slider to synchronously adjust the horizontal spacing, adapting to tobacco leaf hanging rods of different widths. The spacing of the fixed placement structure can be flexibly adjusted without disassembly and reassembly, saving adjustment time. Through lead screw shaft transmission, the slider movement accuracy is high, meeting the needs of refined operations within the curing barn.

[0014] Secondly, this utility model opens the cover plate (rotates around the hinge point), places the tobacco hanging rod horizontally into the mounting semicircular groove of the mounting base plate, closes the cover plate so that the mounting semicircular groove of the cover plate is aligned with the base plate, tightens the locking screw, and fixes the tobacco hanging rod between the mounting base plate and the cover plate to prevent shaking during loading and unloading, and avoids tobacco leaves falling or breaking due to shaking of the device during loading and unloading.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] The following detailed description, in conjunction with the accompanying drawings, illustrates the technical solution of an adjustable electric telescopic frame for production, provided by various embodiments of this utility model.

[0018] Reference Figures 1 to 5 As shown, this utility model embodiment provides an adjustable electric telescopic frame for production, including a support base 1, a multi-stage electric cylinder 2, a support frame 3, an adjustment and mounting structure 4, and a fixed placement structure 5. The multi-stage electric cylinder 2 is vertically mounted on the support base 1, and a mounting plate 21 is provided on the telescopic end of the multi-stage electric cylinder 2. The bottom of the support frame 3 is provided with a support plate 31, and the support plate 31 is detachably connected to the mounting plate 21. The adjustment and mounting structure 4 is horizontally mounted on the top of the support frame 3, and the fixed placement structure 5 is mounted on the adjustment and mounting structure 4.

[0019] Working principle: In use, depending on the length of the tobacco hanging rod, the rotating installation structure drives the fixed placement structure 5 to work, so that the fixed placement structure 5 adapts to the length of the hanging rod, and the position of the hanging rod is locked and fixed by the fixed placement structure 5; then, the telescopic frame is moved to the designated position in the curing barn by the pulley 8 at the bottom of the support base 1, and the switch 10 on the side wall of the support base 1 is turned on, and the lithium battery 9 powers the multi-stage electric cylinder 2; the multi-stage electric cylinder 2 drives the installation plate 21 at the telescopic end and the upper support frame 3 to rise and fall according to the height requirements of tobacco loading and unloading, such as adapting to different layers of tobacco hanging racks in the curing barn, and adjusts to the target height. After the tobacco loading is completed, the telescopic frame is moved to the tobacco hanging position in the curing barn, and the dry tobacco is unloaded by reversing the operation.

[0020] It should be noted that the multi-stage electric cylinder 2 is prior art and can be referenced in existing patent application number CN202121278653.8.

[0021] Specifically, the adjustment and mounting structure 4 includes a mounting frame 41, an adjusting bidirectional lead screw shaft 42, an adjusting disc 43, and two sliders 44. The mounting frame 41 is horizontally mounted on the top of the support frame 3. A sliding groove 45 is provided inside the mounting frame 41. The adjusting bidirectional lead screw shaft 42 is rotatably connected inside the mounting frame 41. The adjusting disc 43 is fixed to the end of the adjusting bidirectional lead screw shaft 42. The two sliders 44 are symmetrically slidably connected inside the sliding groove 45. The two sliders 44 are threadedly connected to the adjusting bidirectional lead screw shaft 42.

[0022] Rotating the adjusting disc 43 causes the adjusting bidirectional lead screw shaft 42 inside the mounting frame 41 to rotate. Because the two sliders 44 are threadedly connected to the adjusting bidirectional lead screw shaft 42 and slide symmetrically in the slide groove 45, when the lead screw shaft rotates, the two sliders 44 move towards or away from each other along the slide groove 45, thereby driving the fixed placement structure 5 installed on the sliders 44 to synchronously adjust the horizontal spacing to adapt to tobacco leaf hanging rods of different widths. The spacing of the fixed placement structure 5 can be flexibly adjusted without disassembly and reassembly, saving adjustment time. Through the lead screw shaft transmission, the slider 44 moves with high precision, meeting the needs of fine operation in the curing barn.

[0023] Specifically, the fixed placement structure 5 includes two mounting components 50 respectively disposed on two sliders 44. Each mounting component 50 includes a mounting base plate 51, a cover plate 52 and a locking screw 53. The end of the mounting base plate 51 is mounted on the slider 44, one end of the cover plate 52 is hinged to the mounting base plate 51, and the locking screw 53 is threaded onto the cover plate 52 for connection with the mounting base plate 51. Both the mounting base plate 51 and the cover plate 52 are provided with a plurality of correspondingly disposed mounting semicircular grooves 54.

[0024] Open the cover plate 52 and rotate it around the hinge point. Place the tobacco hanging rod horizontally into the mounting semicircular groove 54 of the mounting base plate 51. Close the cover plate 52 so that the mounting semicircular groove 54 of the cover plate 52 is aligned with the base plate. Tighten the locking screw 53 to fix the tobacco hanging rod between the mounting base plate 51 and the cover plate 52 to prevent shaking during loading and unloading, and to avoid the tobacco leaves falling or breaking due to the shaking of the device during loading and unloading.

[0025] Specifically, the mounting plate 21 and the support plate 31 are connected by four bolts 32.

[0026] When it is necessary to replace the support frame 3 with a different specification, such as to adapt to tobacco leaf hangers of different lengths, unscrew the four bolts 32 between the mounting plate 21 and the support plate 31, remove the original support frame 3, align the support plate 31 of the new support frame 3 with the mounting plate 21, and retighten the bolts 32 to complete the replacement.

[0027] Specifically, the bottom of the multi-stage electric cylinder 2 is provided with a mounting plate 6, and the bottom of the mounting plate 6 is provided with a rotary bearing 7. The mounting plate 6 is rotatably connected to the top of the support base 1 through the rotary bearing 7.

[0028] When it is necessary to adjust the direction of tobacco loading and unloading, such as turning from one side of the curing barn to the other, push the support frame 3. Since the mounting plate 6 at the bottom of the multi-stage electric cylinder 2 is connected to the support base 1 through the rotary bearing 7, the mounting plate 6 drives the multi-stage electric cylinder 2 and the support frame 3 to rotate around the support base 1 as a whole. After adjusting to the target direction, stop. The direction can be adjusted without moving the entire support base 1, which is especially suitable for the turning needs in the narrow space of the curing barn, further optimizing the operation efficiency and avoiding the inconvenience of operation caused by space limitations.

[0029] Specifically, the bottom of the support base 1 is equipped with four pulleys 8. The four pulleys 8 can drive the entire device to move inside the tobacco room and hang the tobacco leaves inside the tobacco room.

[0030] Specifically, the support base 1 is equipped with a lithium battery 9 that supplies power to the multi-stage electric cylinder 2, and a switch 10 connected to the multi-stage electric cylinder 2 is provided on the side wall of the support base 1. The switch 10 can control the lifting and lowering of the multi-stage electric cylinder 2.

[0031] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
