Description

Technical Field

[0001] The utility model belongs to the technical field of labeling machines, and in particular relates to a self-heating device for a labeling machine. Background Art

[0002] Labeling machine is a device that sticks cold glue, hot melt glue and self-adhesive labels on specified packaging containers. Labeling machine is an indispensable part of modern packaging. At present, the types of labeling machines produced in my country are gradually increasing, and the technical level has also been greatly improved. It has shifted from the backward situation of manual and semi-automatic labeling to the pattern of automated high-speed labeling machines occupying the majority of the market.

[0003] Most of the current rotary labeling machines use a transmission line to transmit bottles. The transmission line transmits the bottles to the main turntable, which is rotatably installed above the support seat. Multiple sub-turntables are rotatably connected to the main turntable. The sub-turntables are arranged in a circular array along the edge of the main turntable. The bottles are transmitted to the sub-turntable by the transmission line. The main turntable sends the labeled bottles to the exit of the labeling machine and is sent away by the transmission line. A sub-motor is fixedly installed at the position of each sub-turntable on the main turntable. The output shaft of the sub-motor is fixedly connected to the sub-turntable. The main motor drives the main turntable to rotate, so that the bottle revolves on the main turntable to complete the transmission of the bottle. The sub-motor drives the sub-turntable to rotate, so that the bottle rotates on the sub-turntable to cooperate with the labeling station to complete the labeling.

[0004] Since multiple sub-motors generate a lot of heat during operation, a fan is usually installed in the support base to blow air to the sub-motors through the holes on the top of the support base to cool the sub-motors and avoid damage due to overheating, so as to ensure their service life. However, the fan consumes electricity during operation, which is not conducive to energy saving and environmental protection. Utility Model Content

[0005] The main technical problem to be solved by the utility model is to provide a self-heating device for a labeling machine, which can replace the fan to perform heat dissipation treatment on the sub-motor, thereby reducing energy consumption and being energy-saving and environmentally friendly.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A self-heating device for a labeling machine comprises a main turntable, to which a plurality of sub-turntables are rotatably connected, and the plurality of sub-turntables are arranged in a circular array along the edge of the main turntable, a sub-motor is fixedly mounted at a position on the main turntable corresponding to each sub-turntable, and the output shaft of the sub-motor is fixedly connected to the sub-turntable, a cylindrical shield is fixedly connected to the outer circumferential surface of the main turntable, an accommodating cavity is formed in the shield, the sub-motor is located in the accommodating cavity, a circular ring-shaped mounting plate is fixedly connected to the bottom end of the shield, a plurality of blowing assemblies are arranged on the mounting plate, and the plurality of blowing assemblies are arranged in an array along the circumference of the mounting plate, and air outlet holes are opened on the side wall of the shield.

[0008] The following is a further optimization of the above technical solution by the present invention:

[0009] The blowing component comprises a mounting hole provided on the mounting plate, a blade is fixedly connected in the mounting hole, and an angle α is set between the blade and the mounting plate.

[0010] Further optimization: the numerical range of the angle α is 10°≤α≤40°.

[0011] Further optimization: the preferred value of the angle α is 20°±1°.

[0012] Further optimization: the shield is formed by connecting multiple arc-shaped plates.

[0013] The utility model rationally designs the blowing component and the structure and position of the air outlet, so that when the labeling machine is working, flowing air is naturally formed around the sub-motor. The power source comes from the main motor, and no additional power is required, which is energy-saving and environmentally friendly. Moreover, compared with the cooling by the fan, the airflow around the sub-motor in this structure is more uniform and stable, and the cooling effect is better.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1-4 As shown: A self-heating device for a labeling machine includes a main turntable 1, on which multiple sub-turntables are rotatably connected. The multiple sub-turntables are arranged in a circular array along the edge of the main turntable 1. A sub-motor 2 is fixedly installed at the position of each sub-turntable on the main turntable 1, and the output shaft of the sub-motor 2 is fixedly connected to the sub-turntable.

[0021] The main turntable 1 is fixedly mounted on the main shaft 6 , and the main shaft 6 is rotatably connected to a support base, on which a main motor for driving the main shaft 6 to rotate is mounted.

[0022] In this design, the main motor drives the main shaft 6 to rotate and then drives the main turntable 1 to rotate, so that the bottles revolve on the main turntable 1 to complete the bottle transmission. The sub-motor 2 drives the sub-turntable to rotate, so that the bottles rotate on the sub-turntable to cooperate with the labeling station to complete the labeling.

[0023] A cylindrical shield 3 is fixed to the outer circumferential surface of the main turntable 1, and an accommodating cavity is formed inside the shield 3. The sub-motor 2 is located in the accommodating cavity. A circular ring-shaped mounting plate 4 is fixed to the bottom end of the shield 3, and a plurality of blowing components 5 are arranged on the mounting plate 4. The plurality of blowing components 5 are arranged in an array along the circumference of the mounting plate 4.

[0024] With this design, the rotation of the main turntable 1 drives the shield 3 to rotate, and the rotation of the shield 3 drives the blowing assembly 5 on the mounting plate 4 to rotate, forming flowing air in the accommodating cavity to cool the sub-motor 2. The power source of the blowing assembly 5 comes from the main motor and does not require additional power. Compared with the cooling by the fan, the airflow around the sub-motor 2 in this structure is more uniform and stable.

[0025] An air outlet 301 is formed on the side wall of the shield 3 .

[0026] With this design, air flows out from the air outlet 301, which facilitates the flow of air in the receiving cavity.

[0027] The shield 3 is formed by connecting a plurality of arc-shaped plates, so that the shield 3 is easier to process and manufacture.

[0028] The blowing assembly 5 includes a mounting hole 401 formed on the mounting plate 4 . A blade 501 is fixedly connected to the mounting hole 401 . An angle α is formed between the blade 501 and the mounting plate 4 .

[0029] With this design, the processing of the blowing component 5 is more convenient. It is only necessary to use a laser cutting machine to cut the blade 501 at the position of the mounting hole 401 of the mounting plate 4, and then bend the blade 501 to form an angle between the blade 501 and the mounting plate 4, thereby realizing the blowing requirements of the blowing component 5. The processing is simple and the manufacturing cost is low.

[0030] The numerical range of the angle α is 10°≤α≤40°.

[0031] The preferred value of the angle α is 20°±1°.

[0032] With this design, when the main turntable 1 rotates at the same speed, the sub-motor 2 is subjected to greater wind force and has a better cooling effect.

[0033] When the labeling machine is working, the main motor drives the main shaft 6 to rotate and then drives the main turntable 1 to rotate, so that the bottles revolve on the main turntable 1 to complete the bottle transmission. The sub-motor 2 drives the sub-turntable to rotate, so that the bottles rotate on the sub-turntable to cooperate with the labeling station to complete the labeling.

[0034] At the same time, the rotation of the main turntable 1 drives the shield 3 to rotate, and the rotation of the shield 3 drives the blades 501 on the mounting plate 4 to rotate, forming flowing air in the accommodating cavity, cooling the sub-motor 2, and the hot air flows out from the air outlet 301.

[0035] The power source of this structure comes from the main motor, and no additional power is required. Compared with the cooling by the fan, the airflow around the neutron motor 2 in this structure is more uniform and stable, and the cooling effect is better.

[0036] For ordinary technicians in this field, based on the teachings of this utility model, without departing from the principles and spirit of this utility model, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of this utility model.
