[0022] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0023] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0024] The present application will be further described below with reference to the accompanying drawings:

[0025] like Figures 1 to 3As shown, the present application provides a top plate lifting and adjusting device, including a base 1, a top plate 2, a lifting platform 3, a first drive assembly 4 and a second drive assembly 5. A plurality of columns 6 are provided on the base 1, and the lifting platform 3 is slidingly connected to the columns 6 above the base 1. The first drive assembly 4 and the second drive assembly 5 are both provided on the lifting platform 3. The top plate 2 is slidingly connected to the columns 6 between the base 1 and the lifting platform 3. The base 1, the top plate 2 and the lifting platform 3 are all connected and supported by the columns 6, which can improve the connection stability among the three, thereby effectively overcoming the reaction force received by the top plate 2 during the descent, reducing the shaking of the top plate 2, improving the processing accuracy, and also improving the service life.

[0026] The first drive assembly 4 is connected to the top plate 2 through the lifting platform 3. The first drive assembly 4 is suitable for making the top plate 2 reciprocate. During the descent of the top plate 2, it can cooperate with the base 1 to press and form the box body raw material or punch and separate it (when the top plate lifting and adjusting device is used on a forming machine, the top plate 2 can cooperate with the base 1 to press and form the box body raw material during the descent. At this time, the distance between the top plate 2 and the base 1 when it descends can determine the pressing quality. When the top plate lifting and adjusting device is used on a punching machine, the top plate 2 can cooperate with the base 1 to punch and separate the box body raw material during the descent. At this time, the distance between the top plate 2 and the base 1 when it descends can determine the punching quality). After the top plate 2 rises, it can allow the formed box body to pass through and be replaced with the next box body raw material, thereby realizing efficient processing of the assembly line.

[0027] In some embodiments, the first driving assembly 4 is suitable for driving the top plate 2 to perform reciprocating motion through a connection form such as a crank connecting rod or an eccentric wheel, so that the top plate 2 can slide and rise and fall along the column 6.

[0028] A lifting linkage 7 is provided between the column 6 and the lifting platform 3. The lifting linkages 7 are connected to each other. The second drive assembly 5 is connected and is suitable for driving at least one lifting linkage 7 so that all the lifting linkages 7 can be lifted and lowered synchronously. The driving method is simple and efficient, and the layout cost is low. By driving one of the lifting linkages 7, the lifting platform 3 can be stably slid and lifted along the column 6 as a whole, thereby improving the stability of the lifting platform 3 before and after adjustment, making it less likely to tilt and ensuring processing accuracy.

[0029] like Figure 3 In the embodiment shown, a screw rod portion 61 is provided on the column 6, and a sleeve 71 is provided on the lifting linkage 7. The sleeve 71 is rotatably connected to the lifting platform 3, and the sleeve 71 is threadedly connected to the screw rod portion 61. The sleeve 71 is suitable for moving along the screw rod portion 61. The screw rod portion 61 can convert the rotational motion of the sleeve 71 on the lifting linkage 7 into a linear motion along the length direction of the column 6, and the rotation ratio is large. Therefore, the lower limit of the lifting amplitude of the lifting linkage 7 along the column 6 can be controlled lower, thereby greatly improving the adjustment accuracy.

[0030] like Figure 3 In the embodiment shown, a reinforced shaft seat 72 is provided on the outer side of the shaft sleeve 71. The reinforced shaft seat 72 is rotatably connected to the shaft sleeve 71 and is fixedly connected to the lifting platform 3. The reinforced shaft seat 72 is used to improve the connection stability between the shaft sleeve 71, the lifting platform 3 and the column 6, and to improve the structural strength.

[0031] In some embodiments, a transmission belt 8 is provided between the lifting linkages 7 , a first connecting portion 73 is provided on the lifting linkage 7 , and the transmission belt 8 is connected to the first connecting portion 73 on each lifting linkage 7 .

[0032] In some embodiments, the transmission direction transmitted by the transmission belt 8 to each first connecting part 73 is consistent, wherein the simplest connection form between the transmission belt 8 and each lifting linkage 7 is that the transmission belt 8 is connected around the outside of all lifting linkages 7 in a clockwise or counterclockwise direction.

[0033] In some embodiments, a second connecting portion 74 is provided on the lifting linkage 7 connected to the second drive assembly 5. The second connecting portion 74 is directly connected to the second drive assembly 7, which can have a higher transmission structure strength.

[0034] In some embodiments, the first coupling portion 73 and the second coupling portion 74 are fixedly connected to the shaft sleeve 71 , and the first coupling portion 73 and the second coupling portion 74 are arranged along a circumferential side of the shaft sleeve 71 .

[0035] In some embodiments, a second connecting portion 74 is provided on the lifting linkage 7 connected to the second drive component 5. The second connecting portion 74 is connected to the second drive component 7 through a transmission belt 8. The second drive component 5 and the lifting linkage 7 can be arranged at intervals, which makes the arrangement more convenient and free.

[0036] like Figures 1 to 3 In the embodiment shown, the transmission belt 8 is a chain, the first connecting portion 73 and the second connecting portion 74 are sprockets, the chain and the sprocket are suitable for engaging with each other, and the matching form of the chain and sprocket has higher structural strength and can have higher transmission stability.

[0037] In some embodiments, the transmission belt 8 may be a belt, and the first coupling portion 73 and the second coupling portion 74 may be friction wheels.

[0038] In some embodiments, the diameter of the second coupling portion 74 is larger than the diameter of the first coupling portion 73. In the present application, when the first coupling portion 73 and the second coupling portion 74 are in the form of a sprocket or a turntable, the first coupling portion 73 and the second coupling portion 74 are usually coaxially arranged, that is, the angles through which the first coupling portion 73 and the second coupling portion 74 rotate are consistent. Therefore, by optimizing the relationship between the diameters of the first coupling portion 73 and the second coupling portion 74, the transmission ratio of the second drive assembly 5 to the shaft sleeve 71 can be changed, that is, the diameter of the second coupling portion 74 can be increased as much as possible, the transmission efficiency of the second drive assembly 5 can be reduced, the rotation amount of the shaft sleeve 71 can be reduced, and the amplitude of the linear motion of the shaft sleeve 71 can be reduced, thereby improving the lifting accuracy of the lifting linkage 7. Reducing the diameter of the second coupling portion 74 can make the structure of each lifting linkage 7 more compact. Since there are a large number of lifting linkages 7, such a design can effectively reduce space occupancy and improve space utilization.

[0039] like Figure 3 In the embodiment shown, the connection plane between the transmission belt 8 and each first connection part 73 is located in the first plane, and the first plane is perpendicular to the column 6. In the present application, the connection plane between the transmission belt 8 and each first connection part 73 can be understood as the rotation plane of the first connection part 73. The first plane is parallel to the horizontal plane, and the connection plane between the transmission belt 8 and each first connection part 73 also needs to be parallel to the horizontal plane. By optimizing the connection plane of the first connection part 73, the structural interference when the transmission belt 8 enters or leaves the first connection part 73 can be reduced or even eliminated, and the wear between the transmission belt 8 and the first connection part 73 can be reduced, thereby improving the stability of use and service life.

[0040] like Figure 2 In the embodiment shown, the columns 6 are arranged symmetrically about the geometric center of the top plate 2. Since the columns 6 play a supporting role, when the top plate 2 and the base 1 are close, the force generated will be transmitted to the columns 6 through various structures. Arranging the columns 6 symmetrically about the geometric center of the top plate 2 can improve the uniformity of force between the top plate 2 and the columns 6, avoid uneven force on individual parts of the top plate 2 and causing distortion and tilting, ensure the accuracy during pressing or punching, and improve the service life.

[0041] In some embodiments, a limit cover 62 is provided at the top end of the column 6 , and the limit cover 62 is suitable for limiting the rise of the lifting linkage 7 .

[0042] Among them, Figures 1 to 3 As shown, when the screw rod part 61 is located at the top of the column 6, the limit cover 62 can be threadedly connected to the top end of the screw rod part 61, which is easy to install. At the same time, it can limit the lifting linkage 7, preventing the lifting linkage 7 from being lifted too high and detached from the screw rod part 61, thereby ensuring the effectiveness of the lifting linkage 7.

[0043] The present application also provides a packaging device, including an upper mold, a lower mold and a top plate lifting and adjusting device of any of the above embodiments, the upper mold is arranged below the top plate 2, and the lower mold is arranged above the base 1, and the top plate 2 and the base 1 are suitable for making the upper mold and the lower mold close to each other and combined, thereby realizing the pressing and forming or punching and splitting of the box body.

[0044] It can be understood that by adjusting the lifting platform 3, the pressing or punching distance between the upper mold and the lower mold can be changed, thereby optimizing the molding quality of the box body, and the top plate lifting adjustment device in this application can maximize the effect of the adjustment of the lifting platform 3 through synchronous and high-precision adjustment.

Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and the specification only describe the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application.
