Description

Technical Field

[0001] The utility model relates to the field of electronic label packaging, in particular to a bellows of an electronic label packaging machine. Background Art

[0002] When packaging electronic tags, multiple steps are required, such as dispensing glue on the antenna and installing the chip. Since the antenna is in a strip shape, the strip antenna needs to be kept in a tensioned state between two adjacent steps to ensure the processing accuracy of the subsequent steps.

[0003] However, due to the particularity of the antenna, it is not possible to use a traditional tensioning mechanism such as a tensioning wheel for tensioning. Therefore, a bellows is used in traditional electronic tag packaging equipment to tension the antenna. A traditional bellows has a large through-hole area on its bottom plate, and a guide rail is provided on the top plate of the bellows. The guide rail is connected to a closing plate. The closing plate of this structure is equivalent to a single cantilever state. When the fan is opened, the two closing plates will shake, resulting in the two closing plates no longer being parallel to each other. The inner wall of the closing plate may collide with the edge of the antenna, or affect the sealing of the space between the two closing plates, thereby affecting the tensioning effect.

[0004] There is another structure of bellows on the market. Its guide rail is not set on the top plate of the bellows, but inside the side plate of the bellows. Therefore, it can solve the above problem to a certain extent. However, when this bellows is working, the guide rail is located on the inside of the tensioned antenna. Therefore, when connecting or adjusting the antenna, the position of the guide rail must be considered, and the operation is relatively cumbersome.

[0005] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0006] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes an electronic label packaging machine bellows with simple structure, ingenious design, reasonable layout, stable state of the closing plate during operation and effective guarantee of the tensioning effect.

[0007] The technical solution of the utility model is: an electronic label packaging machine bellows, including a shell 1, characterized in that: the top of the shell 1 is open, and electric push rods 2 are arranged on the two end plates of the shell 1, and the working end of the electric push rod 2 is connected to the centroid of the closing plate 3, the closing plate 3 matches the shape of the cross section of the shell 1, and the two closing plates 3 are parallel to each other, and sliders 4 are arranged on the two side edges of the closing plate 3, and the sliders 4 are slidably connected to the slide rails 8, and the slide rails 8 are arranged on the two side plates of the shell 1, and the slide rails 8 are distributed along the length direction of the shell 1.

[0008] A plurality of through holes 6 distributed in an array are provided on the bottom plate 5 of the housing 1 . The array formed by the through holes 6 is located between the two closed plates 3 . A fan 7 is provided on the bottom plate 5 below the through holes 6 .

[0009] The through hole array composed of a plurality of through holes 6 has a width smaller than the minimum distance between two closing plates 3 .

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The bellows of the electronic tag packaging machine of this structural form has a simple structure, ingenious design and reasonable layout. It is designed to solve the problems existing in the working process of the traditional bellows of the packaging machine, and a special structure is designed. It can adjust the distance between the two closing plates according to actual needs, so as to adapt to antennas of different widths, and the movement of the closing plates is smooth and reliable. At the same time, the closing plates will not swing or shake, which can ensure the sealing effect between the closing plates and the inner wall of the shell, and further ensure the tensioning effect of the antenna. At the same time, the guide rails supporting the two closing plates are located on the outside of the box body, and therefore are also located on the outside of the tensioned antenna. In this way, whether installing or adjusting the antenna, it will not be affected by the guide rails, and the operation process is relatively simple and convenient; and the manufacturing process of this bellows is simple and the manufacturing cost is low, so it can be said that it has many advantages, and is particularly suitable for promotion and application in this field, and its market prospects are very broad.

[0015] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figure 1 , Figure 2 , Figure 3 As shown: A bellows for an electronic label packaging machine, comprising a shell 1 as a basis, the top of the shell 1 is open, and electric push rods 2 are arranged on the two end plates of the shell 1, and the working end of the electric push rod 2 is connected to the centroid of the closing plate 3, the closing plate 3 matches the shape of the cross section of the shell 1, and the two closing plates 3 are parallel to each other, and sliders 4 are arranged on the two side edges of the closing plate 3, and the sliders 4 are slidably connected to the slide rails 8, and the slide rails 8 are arranged on the two side plates of the shell 1, and the slide rails 8 are distributed along the length direction of the shell 1,

[0016] A plurality of through holes 6 distributed in an array are provided on the bottom plate 5 of the housing 1 . The array formed by the through holes 6 is located between the two closed plates 3 . A fan 7 is provided on the bottom plate 5 below the through holes 6 .

[0017] The working process of the bellows of the electronic tag packaging machine of the embodiment of the utility model is as follows: in the initial state, the strip antenna 9 is located in the cavity between the two closed plates 3, and the antenna 9 naturally droops to form a U shape. When the antenna 9 needs to be kept in a tensioned state, the fan 7 is started by the control system, and the fan 7 draws out the air in the cavity between the two closed plates 3 through the through holes 6 distributed in an array. The generated adsorption force will make the bottom end of the antenna 9 tend to move toward the through hole 6, so that the antenna 9 is always kept in a tensioned state during the movement;

[0018] If it is necessary to perform tensioning and transmission operations on antennas 9 of different specifications, it is only necessary to issue a command through the control system to control the electric push rod 2 to work, and the electric push rod 2 drives the closing plate 3 to move along the length direction of the shell 1. After moving to a suitable position, the staff controls the electric push rod 2 to stop working. During the above movement, the sliders 4 connected on both sides of the closing plate 3 will slide on the slide rails 8 to ensure that the closing plate 3 can move smoothly; in this way, the distance between the two closing plates 3 can be adjusted to adapt to antennas 9 of different widths;

[0019] The width of the through hole array formed by the plurality of through holes 6 is smaller than the minimum spacing between the two closing plates 3. This design can maximize the use of the fan 7, thereby obtaining a better tensioning effect when using a fan 7 of equal power.
