Description

Technical Field

[0001] This utility model relates to the field of packaging machine frame technology, and specifically to a horizontal lifting frame. Background Technology

[0002] In the current development of mechanization, lifting mechanisms for materials or components are indispensable. For example, some ring-type PE film packaging machines contain lifting mechanisms. However, commonly used lifting mechanisms generally use closed-loop chains to lift objects. However, closed-loop chain lifting results in the entire load of the object's weight being on the corresponding chain. Compared to open-loop chain lifting structures where one end of the chain connects to the object and the other end connects to a counterweight, closed-loop chain lifting requires a larger power drive motor. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a horizontal lifting frame that has the advantage of reducing the power of the drive components, thus solving the problems in the background technology.

[0004] The horizontal lifting frame of this utility model includes:

[0005] A fixed frame, comprising four columns, a mounting frame, and support components, wherein the mounting frame has rectangular edges and is detachably connected to the columns;

[0006] A lifting frame is installed inside a fixed frame, and a set of rollers that are rotatably connected to the column is installed on the lifting frame;

[0007] The driving component includes a main driving mechanism and a slave driving mechanism, which are respectively disposed on both sides of the mounting frame.

[0008] The main drive mechanism includes a drive shaft mounted on one side of the mounting frame via bearings, and a drive motor for driving the drive shaft to rotate. Both ends of the drive shaft are provided with a first drive sprocket and a second drive sprocket.

[0009] The driven mechanism includes a driven shaft, which is mounted on a mounting frame via bearings, and the driven shaft is located on the side of the mounting frame away from the drive shaft; driven sprockets are mounted at both ends of the driven shaft;

[0010] A first chain is installed above the first driving sprocket and the driven sprocket. A first counterweight is installed at the end of the first chain near the first driving sprocket. The end of the first chain is connected to a corner of the lifting frame.

[0011] A second chain is installed above the second drive sprocket. One end of the second chain is connected to the first counterweight, and the other end of the second chain is connected to a corner adjacent to the lifting frame.

[0012] The driven mechanism also includes a redirecting sprocket corresponding to the driven sprocket; a third chain is installed on the redirecting sprocket, one end of the third chain is connected to the lifting frame, and a second counterweight is installed on the other end.

[0013] The four corners of the mounting frame are fixedly connected with mating columns that are adapted to the uprights. The mating columns and the uprights are all hollow uprights that are interconnected. The internal cavities of the mating columns and the uprights form movable cavities for the movement of the first counterweight or the second counterweight.

[0014] The edge between the mounting frame and the first driving sprocket and driven sprocket is designated as the mounting edge, and the mounting edge is provided with a movable groove for accommodating the first chain.

[0015] Both the drive shaft and the driven shaft are installed on the mounting side through the movable groove. Both ends of the movable groove are provided with mounting holes that communicate with the movable cavity. The first drive sprocket, the second drive sprocket, the driven sprocket, and the redirecting sprocket are installed inside the mounting holes respectively.

[0016] The mounting edge is an H-beam, the upper groove of the H-beam is a movable groove, and both ends of the H-beam are fixedly installed with reinforcing end plates.

[0017] The column is a rectangular column;

[0018] The roller assembly includes two rollers, which are distributed at right angles and are rolledly connected to the two sides adjacent to the corresponding columns.

[0019] The four columns are arranged in pairs, and the two columns in each pair are fixedly connected by a support to form a frame component. The two frame components are detachably connected by a connector.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. The first and second drive sprockets of this utility model rotate, thereby causing the first and second chains to rotate, forming a double open-loop chain. This can ensure the synchronization of the lifting points on both sides of the lifting frame and the consistency of the movement direction of the lifting points. Furthermore, by hiding the first and second counterweights through the movable cavity, the installation range of the drive components can be reduced, saving installation space. At the same time, the use of an open-loop chain can reduce the power required by the drive motor.

[0022] 2. This utility model effectively ensures the balance and stability of the lifting frame's counterweight by setting up a reversing sprocket, a third chain, and a second counterweight, in conjunction with the setting of the first counterweight. Furthermore, the rolling connection between the roller assembly and the column further ensures the stability of the lifting frame during lifting.

[0023] 3. This utility model uses two of the four columns to form a frame component by fixing them together with a support member. The two frame components are detachably connected by a connector, and the mounting frame is detachably connected to the columns, which facilitates modular transportation and installation of the equipment.

[0040] The fixed frame 1 includes four columns 101, a mounting frame 102 and a support 103. The mounting frame 102 has a rectangular edge and is detachably connected to the columns 101.

[0041] The lifting frame 2 is installed inside the fixed frame 1, and the lifting frame 2 is equipped with a roller assembly 201 that is rotatably connected to the column 101.

[0042] The drive assembly 3 includes a main drive mechanism 31 and a slave drive mechanism 32, which are respectively disposed on both sides of the mounting frame 102.

[0043] The main drive mechanism 31 includes a drive shaft 311 mounted on one side of the mounting frame 102 via bearings, and a drive motor 314 for driving the drive shaft 311 to rotate. Both ends of the drive shaft 311 are provided with a first drive sprocket 312 and a second drive sprocket 313.

[0044] Drive mechanism 32 includes driven shaft 321, which is mounted on mounting frame 102 by bearings and is located on the side of mounting frame 102 away from drive shaft 311; driven sprockets 322 are mounted on both ends of driven shaft 321.

[0045] A first chain 33 is installed above the first driving sprocket 312 and the driven sprocket 322. A first counterweight 34 is installed at one end of the first chain 33 near the first driving sprocket 312. The end of the first chain 33 is connected to one corner of the lifting frame 2.

[0046] A second chain 35 is installed above the second drive sprocket 313. One end of the second chain 35 is connected to the first counterweight 34, and the other end of the second chain 35 is connected to a corner adjacent to the lifting frame 2.

[0047] The drive mechanism 32 also includes a redirecting sprocket 36 corresponding to the driven sprocket 322; a third chain 37 is installed on the redirecting sprocket 36, one end of the third chain 37 is connected to the lifting frame 2, and a second counterweight 38 is installed on the other end; through the setting of the redirecting sprocket 36, the third chain 37 and the second counterweight 38, in conjunction with the setting of the first counterweight 34, the balance and stability of the counterweight of the lifting frame 2 are effectively guaranteed.

[0048] The four corners of the mounting frame 102 are fixedly connected with docking posts 107 that are adapted to the uprights 101. The docking posts 107 and the uprights 101 are all interconnected by hollow uprights 101. The internal cavities of the docking posts 107 and the uprights 101 form movable cavities 104 for the movement of the first counterweight 34 or the second counterweight 38.

[0049] The mounting frame 102 is positioned at the edge between the first drive sprocket 312 and the driven sprocket 322 as a mounting edge 105. The mounting edge 105 has a movable groove 106 for accommodating the first chain 33. Both the drive shaft 311 and the driven shaft 321 pass through the movable groove 106 and are mounted on the mounting edge 105. Both ends of the movable groove 106 have mounting holes 109 that communicate with the movable cavity 104. The first drive sprocket 312, the second drive sprocket 313, the driven sprocket 322, and the redirecting sprocket 36 are correspondingly mounted inside the mounting holes 109.

[0050] The movable groove 106 and the mounting hole 109 provide installation space for the first drive sprocket 312, the second drive sprocket 313, the driven sprocket 322, the redirecting sprocket 36, and the first chain 33, and also provide protection for the first chain 33.

The rollers of the lifting frame 2 can ensure the stability of the lifting frame 2 when it is raised and lowered.

[0053] The four columns 101 are arranged in pairs. The two columns 101 in each pair are fixedly connected by a support member 103 to form a frame component. The two frame components are detachably connected by a connector 108. This arrangement allows the fixed frame 1 to consist of two frame components, a mounting frame 102 and a connector 108, which facilitates modular transportation and installation of the equipment.

[0054] Working principle:

[0055] When the drive motor 314 starts, the first drive sprocket 312 and the second drive sprocket 313 rotate, thereby causing the first chain 33 and the second chain 35 to rotate. Since the connection points of the first chain 33 and the second chain 35 with the lifting frame 2 are located on both sides of the lifting frame 2, the synchronicity of the lifting points on both sides of the lifting frame 2 can be guaranteed. Furthermore, by using the first chain 33 and the second chain 35 to lift the two sides of the lifting frame 2 respectively, the synchronicity of the lifting of the lifting frame 2 can be guaranteed, as well as the consistency of the movement direction of the lifting points of the lifting frame 2.

[0056] The movable cavity 104 in the docking column 107 and the upright column 101 can hide and guide the first counterweight 34 and the second counterweight 38, thereby effectively ensuring the stability of the first chain 33, the second chain 35 and the third chain 37 when the lifting frame 2 is raised and lowered.

[0057] The above are merely embodiments of this utility model and are 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.
