Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for cigarette packaging machines, and in particular to a glue storage device for cigarette packaging machines. Background Technology

[0002] The cigarette packaging machine requires a large amount of glue to bond the cigarette tipping paper and cigarette paper during the production process. The workshop also involves the storage of glue. During the storage process, the glue will separate into upper and lower layers, resulting in the upper layer of glue being thinner and the lower layer of glue being thicker. When the glue is actually used, the physical properties of the glue are not uniform. Glue that is too thick or too thin has a great impact on the cigarette forming and tipping paper splicing, which can easily cause quality problems such as cigarette bursts and tipping paper wrinkles.

[0003] In the existing technology, some glue storage boxes with stirring functions are provided. These boxes can not only store glue but also quickly stir it at a controllable stirring speed, greatly improving the uniformity of the glue and ensuring the quality of cigarette packaging. However, these traditional stirring boxes that use mechanical dynamic seals (the stirring shaft needs to penetrate the box body, and its rotating seal is subject to wear) often have the risk of leakage. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a glue storage device for a cigarette packaging machine, which solves the problem of leakage risk in traditional mechanical dynamic sealing mixing tanks in the prior art.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: a glue storage device for a cigarette packaging machine, including a tank, the tank including an inner liner layer, a phase change material interlayer and a heat insulation shell arranged sequentially from the inside to the outside, and a glue storage cavity is formed inside the inner liner layer;

[0006] The glue storage chamber is equipped with a stirring assembly, which includes a rotating shaft and centrifugally deployable stirring blades. One end of the rotating shaft is fixedly connected to a conductor rotor, and the other end is rotatably connected to the tank body. A permanent magnet rotor is provided on the outside of the tank body corresponding to the conductor rotor.

[0007] The tank body at the bottom projection area of ​​the permanent magnet rotor is provided with only an inner liner layer, and the thickness of the liner layer in the bottom projection area is ≤0.5mm; the permanent magnet rotor and the conductor rotor are coaxially arranged and magnetically coupled through an air gap of 1.5-3mm.

[0008] Optionally, the conductor rotor is a copper-aluminum alloy disc with radial grooves on its surface. These radial grooves reduce the formation of eddy currents.

[0009] Optionally, the inner liner layer is an austenitic stainless steel layer.

[0010] Optionally, the phase change material interlayer is provided with a honeycomb-shaped aluminum alloy frame, and cubic calcium stearate phase change units are encapsulated within the frame.

[0011] Optionally, the insulation shell layer is a polyurethane foam layer. This insulation layer structure reduces the likelihood of adhesive solidification inside the tank.

[0012] Optionally, the tank body is provided with at least one piezoelectric vibration component.

[0013] Optionally, the piezoelectric vibration assembly includes an elastic substrate and a piezoelectric unit. The elastic substrate is disposed on the inner liner layer of the tank, and the piezoelectric unit is disposed on the elastic substrate. The piezoelectric unit can deform the elastic substrate to generate vibration and transmit the vibration to the inner liner layer.

[0014] The beneficial effects of this utility model are:

[0015] This invention uses a coaxial permanent magnet rotor and a conductor rotor, achieving magnetic coupling through a preset air gap value, forming a magnetic coupling that is not in contact with the tank body. When the permanent magnet rotor motor starts rotating, it drives the conductor rotor to rotate, which in turn drives the stirring blades to rotate with the shaft. The stirring blades gradually expand centrifugally, thus using the stirring effect of the blades to prevent the glue from solidifying. Compared to the conventional dynamic sealing structure where the shaft passes through the tank body, glue leakage caused by wear of dynamic sealing elements will not occur, improving the sealing reliability of the glue storage device. At the same time, a piezoelectric vibration component is provided on the tank body to eliminate magnetic slip loss of the magnetic coupling, reducing transmission failure caused by abnormal magnetic slip. In addition, the piezoelectric vibration component also helps to eliminate glue residue on the inner wall of the tank. Attached Figure Description

In the description of this utility model, it should be understood that if terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0025] like Figures 1-6 As shown, this utility model discloses a glue storage device for a cigarette packaging machine, including a tank 1. The tank 1 includes an inner liner layer 11, a phase change material interlayer 12, and an insulation shell 13 arranged sequentially from the inside to the outside. The phase change material interlayer 12 is provided with a honeycomb-shaped aluminum alloy frame, and a cubic calcium stearate phase change unit is encapsulated inside the frame. The insulation shell 13 is a polyurethane foam layer, and the inner liner layer 11 forms a glue storage cavity inside.

[0026] In this embodiment, a stirring assembly is provided in the glue storage cavity. The stirring assembly includes a rotating shaft 21 and centrifugally expandable stirring blades 22. One end of the stirring blades 22 is hinged to the rotating shaft 21. When stationary, they can retract downwards under their own weight. When a certain speed is reached, the stirring blades 22 rotate with the rotating shaft 21 and gradually centrifugally expand, so that the stirring effect of the blades can be adapted to various speeds, improving the applicability of the blades and ensuring the stirring effect.

[0027] In this embodiment, one end of the rotating shaft 21 is fixedly connected to the conductor rotor 23, and the other end is rotatably connected to the tank body 1. For example, a rotating shaft seat is provided at the top inside the tank body 1, and the rotating shaft 21 is rotatably connected to the rotating shaft seat. However, the rotating shaft 21 does not need to penetrate the tank body 1 to avoid leakage of the dynamic seal between the tank body 1 and the rotating shaft 21 during use. The rotating shaft seat limits the rotation of the rotating shaft 21, ensuring that the height position of the conductor rotor 23 is determined during rotation. A permanent magnet rotor 24 is provided outside the tank body 1 corresponding to the conductor rotor 23. The permanent magnet rotor 24 can be driven by a motor, or by a combination of a motor and a reducer, or by other gears, belts, etc. However, the height position of the permanent magnet rotor 24 needs to be kept fixed when driving the conductor rotor 23. The permanent magnet rotor 24 and the conductor rotor 23 are coaxially arranged and magnetically coupled through a 1.5-3mm air gap, that is, a magnetic coupling that does not contact the bottom of the tank body 1 is formed through magnetic coupling.

[0028] In this embodiment, to ensure the magnetic coupling effect, only the inner liner layer 11 is provided in the tank 1 of the bottom projection area of ​​the permanent magnet rotor 24, and the thickness of the inner liner layer 11 in the bottom projection area is ≤0.5mm; and the height position of the permanent magnet rotor 24 needs to be kept fixed when driving the conductor rotor 23. A 1.5-3mm air gap is set for the best magnetic coupling effect. For example, the shaft seat can be threaded to the tank 1 to adjust and determine the height position of the shaft seat, or to adjust the height position of the permanent magnet rotor 24 in conjunction with the preset appropriate air gap value.

[0029] In this embodiment, to reduce eddy current formation in the conductor rotor 23, the conductor rotor 23 is a copper-aluminum alloy disc with radial grooves on its surface. The inner liner 11 is an austenitic stainless steel layer. Austenitic stainless steel is a non-ferromagnetic material and will not interfere with the permanent magnet rotor 24.

[0030] In this embodiment, to eliminate magnetic slip loss in the magnetic coupling and reduce transmission failure caused by magnetic slip abnormalities, at least one piezoelectric vibration assembly is provided on the tank 1. In this embodiment, there are three piezoelectric vibration assemblies evenly distributed around the magnetic coupling area. Each piezoelectric vibration assembly includes an elastic substrate 31 and a piezoelectric unit 32. The elastic substrate 31 is disposed on the inner liner layer 11 of the tank 1, and the piezoelectric unit 32 is disposed on the elastic substrate 31. The piezoelectric unit 32 can cause the elastic substrate 31 to deform to generate vibration and transmit the vibration to the inner liner layer 11. It should be understood that the working principle of the piezoelectric vibration assembly is based on the inverse piezoelectric effect, that is, when an electric field is applied to a part of the crystalline material, the material will undergo mechanical deformation. When working as an actuator (inverse piezoelectric effect), an alternating voltage is applied to cause the piezoelectric element to undergo periodic deformation, generating mechanical vibration. Its vibration frequency is usually consistent with the voltage frequency.

[0031] For example, a circuit operation of a piezoelectric vibration component is provided: a signal generator outputs a low-voltage AC signal to a power amplifier to boost it to a high voltage. This high voltage is then applied to the electrodes of the piezoelectric unit 32 after the capacitive reactance is offset by a matching inductor. The piezoelectric unit 32 generates stretching vibration through the inverse piezoelectric effect, and at the same time transmits the vibration to the elastic substrate 31 through a rigid connection. The two work together to convert electrical energy into vibration energy and output it to the inner liner layer 11.

[0032] The working principle of this utility model is as follows:

[0033] In use, the height of the permanent magnet rotor 24 and the conductor rotor 23 of this utility model is kept fixed. The permanent magnet rotor 24 and the conductor rotor 23 are coaxially arranged and magnetically coupled through a 1.5-3mm air gap to form a magnetic coupling that does not contact the tank body 1. When the permanent magnet rotor 24 is driven by the motor to start rotating, it drives the conductor rotor 23 to rotate, thereby driving the stirring blade 22 to rotate with the rotating shaft 21. The stirring blade 22 gradually expands centrifugally, thereby using the stirring effect of the blade to prevent the glue from solidifying.

[0034] During this process, since the rotating shaft 21 is driven by the permanent magnet rotor 24 and the conductor rotor 23, there is no conventional rotating seal between the rotating shaft 21 and the tank body 1, preventing glue leakage caused by wear of dynamic sealing elements. This ensures the reliability of the glue storage device's seal. Simultaneously, the tank body 1 is equipped with a piezoelectric vibration assembly to eliminate magnetic slip loss in the magnetic coupling, reducing transmission failures caused by abnormal magnetic slip. Furthermore, the piezoelectric vibration assembly also helps eliminate glue residue on the inner wall, preventing the formation of dried deposits.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
