DETAILED DESCRIPTION

For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0040] The shock-absorbing machine feet and the packaging machine provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0041] Embodiment 1:

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, an embodiment of the present application provides a shock-absorbing machine foot, including a machine foot body 1, the main body of which is an elastic tubular body.

[0043] Furthermore, the foot body 1 also includes a plurality of mounting holes 3, which are spaced apart at the top and bottom of the foot body 1; a plurality of bolts 4, which are respectively passed through the mounting holes 3, for fixing the foot body 1 to the ground or an external packaging machine.

[0044] Furthermore, the foot body 1 includes a pair of mounting plates 11 and a pair of arc-shaped elastic plates 12; wherein, the pair of arc-shaped elastic plates 12 are respectively arranged on both sides of the pair of mounting plates 11, and the ends are fixedly connected to the adjacent side walls of each mounting plate 11, and the damping component 2 is installed between the pair of mounting plates 11.

[0045] Preferably, the pair of mounting plates 11 and the pair of arc-shaped elastic plates 12 are both made of rubber and are integrally formed.

[0046] Meanwhile, a packaging machine is disclosed, comprising a machine body 100, a bottom edge of which is provided with a plurality of shock-absorbing machine feet at intervals along the circumferential direction.

[0047] In this embodiment of the present application, due to the adoption of the above structure, nuts for matching the bolts 4 are pre-fixed on the body 100 and the ground, the upper mounting plate 11 is fixed to the body 100 of the packaging machine through the bolts 4, and the lower mounting plate 11 is fixed to the ground through the bolts 4. A pair of arc-shaped elastic plates 12 can effectively buffer longitudinal and lateral vibrations, cooperate with the damping component 2 to absorb vibrations, and achieve a good shock-absorbing effect;

[0048] In actual use, a number of shock-absorbing machine feet can be arranged at the bottom of the external packaging machine according to the size of the external packaging machine, and they can be freely combined and have a wide range of applications.

[0049] Embodiment 2:

[0050] like Figures 1 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes a damping component 2 arranged between a pair of mounting plates 11, which includes a damping shell 21, which is hingedly mounted on the bottom bolt 4 through a lower rod 22; a piston 23, which can be slidably mounted in the damping shell 21 and has microholes on the peripheral side; an upper rod 24, one end of which is fixedly connected to the piston 23, and the other end passes through the damping shell 21 and is hinged to the inner end of the top bolt 4.

[0051] Furthermore, the damping component 2 also includes an inner damping spring 25, which is arranged between the bottom surface of the piston 23 and the bottom surface of the inner cavity of the damping shell 21; an outer damping spring 26, which is sleeved on the outside of the inner damping spring 25, and the top and bottom are respectively abutted against the bottom surface of the piston 23 and the bottom surface of the inner cavity of the damping shell 21.

[0052] Furthermore, the damping component 2 also includes a limiting hole 27, which is arranged at the bottom of the inner cavity of the damping shell 21 and extends into the lower rod 22; a limiting sliding rod 28, which is fixed at the bottom of the piston 23 and the lower end of which can be slidably inserted into the limiting hole 27.

[0053] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the arc-shaped elastic plate 12 will shake left and right or relax up and down during buffering, resulting in a change in the relative position of the corresponding pair of mounting plates 11. Specifically, the top mounting plate 11 moves in four degrees of freedom, namely, up, down, left and right, relative to the bottom mounting plate 11. When the top mounting plate 11 moves left and right, the upper rod 24 and the piston 23 move left and right with the top mounting plate 11, and the damping shell 21 moves left and right around the hinge point between the bottom of the lower rod 22 and the corresponding bolt 4. At the same time, the piston 2 3 is lifted and lowered in the damping shell 21, so that the damping fluid in the damping shell 21 flows through the damping hole to generate a damping force. When the top mounting plate 11 moves up and down, the upper rod 24 and the piston 23 are lifted and lowered accordingly, so that the piston 23 is lifted and lowered in the damping shell 21, so that the damping fluid in the damping shell 21 flows through the damping hole to generate a damping force. When the top mounting plate 11 moves with multiple degrees of freedom at the same time (for example, upper left, lower left, upper right, lower right), the piston 23 can slide in the damping shell 21, so that the damping fluid in the damping shell 21 flows through the damping hole to generate a damping force, thereby providing a damping effect.

[0054] When the piston 23 is lifted and lowered in the damping shell 21, the lower end of the limit slide rod 28 is also lifted and lowered and slid in the limit hole 27 synchronously, which plays a limiting effect and ensures that the force between the peripheral wall of the piston 23 and the inner peripheral wall of the damping shell 21 is uniform;

[0055] The inner shock absorbing spring 25 and the outer shock absorbing spring 26 can provide additional longitudinal shock absorbing effect and can provide shock absorbing support for the piston 23 to prevent the piston 23 from colliding with the bottom of the inner cavity of the damping shell 21 and causing damage in the case of a large longitudinal impact.

[0056] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0057] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
