Description

Technical Field

[0001] This invention relates to the field of filling technology, and in particular to a lifting mechanism and a cooling device. Background Technology

[0002] When bottles are blown into shape in a blow molding machine, the bottom of the bottle is at a high temperature. During the bottle transport process, a cooling water pipe is installed directly below the conveyor track to spray and cool the bottom of the bottle. Since the equipment needs to blow bottle shapes of different heights, it is difficult for the nozzles on the cooling water pipe to meet the requirements at the same time.

[0003] In the existing technology, when blowing bottles of different heights, it is necessary to change nozzles of different heights to meet the cooling requirements. Changing the nozzles one by one takes a long time and seriously affects production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a lifting mechanism and a cooling device that can quickly adjust the height of the nozzle to make it suitable for cooling two types of bottles with set heights, thereby ensuring the production efficiency of the blow molding machine.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A lifting mechanism includes a mounting base, at least two sets of linkage assemblies arranged at intervals along a first direction on the mounting base, an operating rod for connecting all sets of the linkage assemblies, and a limiting member for limiting the operating rod.

[0007] The linkage assembly includes a pair of parallel first and second links arranged at intervals in the vertical direction. The first and second links are perpendicular to the first direction. The two ends of the first and second links are aligned in the vertical direction. Each link is rotatably connected to the mounting base through one end and rotatably connected to the mounting bracket through the other end.

[0008] The operating lever includes a first rod parallel to the first direction and at least two second rods respectively connected to the first rod and perpendicular to the first direction. The second rods are rotatably connected to the first connecting rod in a one-to-one correspondence, and the rotation center lines of all the second rods coincide with each other.

[0009] The operating lever has a first position and a second position, and the limiting member is used to limit the operating lever when it is in the first position and the second position:

[0010] When the operating lever is in the first position, the second rod body is inclined downward along the direction close to the mounting bracket, and the second rod body is perpendicular to the first connecting rod;

[0011] When the operating lever is in the second position, the second lever body is inclined in the direction close to the mounting bracket, and the second lever body is perpendicular to the first connecting rod.

[0012] Preferably, the limiting member is provided with a guide groove that is inclined in the vertical direction and perpendicular to the first direction, and the guide groove includes a first end and a second end;

[0013] When the operating lever is in the first position, the first lever body is located in the first end; when the operating lever is in the second position, the first lever body is located in the second end.

[0014] More preferably, when the operating lever is in the first position, the bearing surface of the first end used to support the first rod body is perpendicular to the second rod body; when the operating lever is in the second position, the bearing surface of the second end used to support the first rod body is perpendicular to the second rod body.

[0015] More preferably, the upper end of the guide groove is bent downward to form a bent portion for supporting the first rod body, the bent portion being either the first end or the second end.

[0016] More preferably, the guide groove is inclined downward along the direction close to the mounting bracket.

[0017] Preferably, the rotation center line of the second rod relative to the first connecting rod passes through the midpoint of the first connecting rod.

[0018] Preferably, when the operating lever is in the first position and the second position respectively, the end of the first connecting rod used to connect the mounting bracket is located on the same vertical line.

[0019] Preferably, the mounting base includes a mounting body located at the bottom and a first connecting post vertically connected to the mounting body, wherein the first connecting rod and the second connecting rod are rotatably connected to the first connecting post through one end of each of them.

[0020] More preferably, the mounting bracket includes a second connecting column suspended above the mounting body, the second connecting column being parallel to the first connecting column, and the first connecting rod and the second connecting rod being rotatably connected to the second connecting column through their other ends.

[0021] A cooling device includes the aforementioned lifting mechanism. The cooling device further includes a cooling pipe for introducing a heat exchange medium and a nozzle with one end connected to the cooling pipe. The cooling pipe includes an arc-shaped pipe body, and the pipe body is connected to the second connecting column.

[0022] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: The lifting mechanism and cooling device of the present invention, by setting a pair of first and second connecting rods respectively rotatably connected at both ends to the mounting base and the mounting bracket, and controlling the rotation and lifting of one end of the first and second connecting rods connected to the mounting bracket around its other end by an operating lever, can automatically lock in the first and second positions respectively. This structure can quickly adjust the height of the mounting bracket. When the lifting mechanism is applied to the cooling device, this structure can quickly adjust the height of the nozzle, making it suitable for cooling two types of bottles with set heights, thereby ensuring the production efficiency of the blow molding machine.

[0035] See Figure 1-4As shown, this embodiment provides a cooling device, including a cooling mechanism and a lifting mechanism for driving the cooling mechanism to perform lifting and lowering movements.

[0036] The cooling mechanism includes a cooling pipe 2 for introducing a heat exchange medium and a nozzle 3 connected to the cooling pipe 2 at one end. In this embodiment, there are multiple nozzles 3, which are spaced apart along the length of the cooling pipe 2. The nozzles 3 are connected to the cooling pipe 2 at their lower ends and spray the heat exchange medium for cooling the bottom of the bottle through their upper ends.

[0037] In this embodiment, the blown bottle 1 is conveyed by the turntable 8 in the blow molding machine. The cooling pipe 2 includes an arc-shaped pipe body 21 located directly below the turntable 8. The two ends of the pipe body 21 are aligned vertically with the bottle inlet and bottle outlet of the turntable 8, respectively. The pipe body 21 and the nozzle 3 are located directly below the conveying trajectory of the bottle 1.

[0038] The lifting mechanism includes a mounting base 4 and at least two sets of components along the first direction (i.e., Figure 1 The linkage assemblies 5 are arranged at intervals on the mounting base 4 (in the direction of the arrows in the image), the operating levers 6 are used to connect all the linkage assemblies 5, and the limiting members 7 are provided on the mounting base 4 to limit the operation levers 6.

[0039] The linkage assembly 5 includes a pair of parallel first links 51 and second links 52 spaced apart in the vertical direction. The first links 51 and second links 52 are perpendicular to the first direction, and the two ends of the first links 51 and the two ends of the second links 52 are aligned vertically. The first links 51 and second links 52 are rotatably connected to the mounting base 4 through their right ends, and rotatably connected to the mounting bracket 9 through their left ends. The cooling pipe 2 is connected to the left side of the mounting bracket 9.

[0040] In this embodiment, the mounting base 4 includes a mounting body 41 located at the bottom and a first connecting post 42 vertically connected to the mounting body 41. A first connecting rod 51 and a second connecting rod 52 are rotatably connected to the first connecting post 42 via their right ends. The mounting bracket 9 includes a second connecting post 91 suspended above the mounting body 41. The second connecting post 91 is vertically arranged and parallel to the first connecting post 42. The first connecting rod 51 and the second connecting post 52 are rotatably connected to the second connecting post 91 via their left ends. With the above structure, the first connecting rod 51, the second connecting rod 52, the first connecting post 42, and the second connecting post 91 form a parallelogram.

[0041] The operating lever 6 includes a first lever 61 parallel to the first direction and at least two second levers 62 respectively connected to the first lever 61 and perpendicular to the first direction. The second levers 62 are rotatably connected to the first connecting rod 51 in a one-to-one correspondence. The rotation center line of the second lever 62 relative to the first connecting rod 51 passes through the midpoint of the first connecting rod 51, and the rotation center lines of all the second levers 62 relative to the first connecting rod 51 coincide with each other.

[0042] The operating lever 6 has a first position and a second position. The limiting member 7 can be used to limit the operating lever 6 at the first position and the second position respectively. The limiting member 7 is provided with a guide groove 71 that is inclined in the vertical direction and perpendicular to the first direction. The guide groove 71 includes a first end 711 and a second end 712. In this embodiment, the guide groove 71 is inclined downward in the direction close to the mounting bracket 9, and the first end 711 is higher than the second end 712.

[0043] in:

[0044] See Figure 1-2 As shown, when the operating lever 6 is in the first position, the first lever 61 is located in the first end 711, and the second lever 62 is inclined downward along the direction close to the mounting bracket 9. The second lever 62 is perpendicular to the first connecting rod 51, forming a self-locking structure. Furthermore, the bearing surface of the first end 711 used to support the first lever 61 is perpendicular to the second lever 62, further ensuring the stability of the self-locking structure.

[0045] See Figure 3-4 As shown, when the operating lever 6 is in the second position, the first lever 61 is located in the second end 712, and the second lever 62 is inclined in the direction close to the mounting bracket 9. The second lever 62 is perpendicular to the first connecting rod 51, forming a self-locking structure. Furthermore, the bearing surface of the second end 712 used to support the first lever 61 is perpendicular to the second lever 62, further ensuring the stability of the self-locking structure.

[0046] See Figure 4 As shown, in this embodiment, the upper end of the guide groove 71 is bent downwards and to the right to form a bent portion for supporting the first rod 61, which is the first end 711. By setting the first end 711 with a bent shape, when the operating lever 6 is in the first position, the first end 711 can stably limit the first rod 61.

[0047] See Figure 2 , Figure 4 As shown, when the operating lever 6 is in the first position and the second position respectively, the end of the first connecting rod 51 used to connect the mounting bracket 9 is located on the same vertical line. This setting ensures that the tube body 21 and the nozzle 3 remain directly below the conveying trajectory of the bottle 1 after the height is adjusted.

[0048] See Figure 2 As shown, when the operating lever 6 is in the first position, the nozzle 3 is positioned relatively high to cool the shorter (i.e., higher-bottomed) bottle 1; see also Figure 4 As shown, when the operating lever 6 is in the second position, the nozzle 3 is positioned relatively low to cool the longer (i.e., lower-bottomed) bottle 1.

[0049] In this embodiment, there is a pair of connecting rod assemblies 5 and limiting members 7. The pair of limiting members 7 are arranged at intervals along the first direction and located between the pair of connecting rod assemblies 5. The length of the first rod 61 is longer than the distance between the pair of limiting members 7. Two second rods 62 are respectively located on the outside of the pair of limiting members 7.

[0050] Obviously, this lifting mechanism can also be used in other places in the blow molding machine where height adjustment is required, and is not limited to its application in the cooling device in this embodiment.

[0051] The working process of this embodiment is described in detail below:

[0052] When the bottle 1 that needs to be cooled is short, slide the operating rod 6 upward along the groove of the guide groove 71, so that the left ends of the first connecting rod 51 and the second connecting rod 52 rotate and rise around their right ends respectively, until the first rod body 61 enters the upper rest position (i.e. enters the first end 711). At this time, the first connecting rod 51 and the second connecting rod 52 rotate into place and are perpendicular to the second rod body 62.

[0053] When the bottle 1 that needs to be cooled is long, slide the operating rod 6 downward along the groove of the guide groove 71, so that the left ends of the first connecting rod 51 and the second connecting rod 52 rotate around their right ends and descend until the first rod body 61 enters the lower rest position (i.e. enters the second end 712). At this time, the first connecting rod 51 and the second connecting rod 52 rotate into place and are perpendicular to the second rod body 62.

[0054] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
