Description

Technical Field

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

[0002] Packaging machines are widely used in industries such as food, pharmaceuticals, chemicals, daily necessities, medical consumables, and biological testing products. They facilitate automated production, making packaging more convenient and efficient, freeing up manpower, reducing costs, and significantly improving production efficiency, creating benefits for businesses. The packaged items can be fixed-shaped products or free-form powders, granules, and liquids.

[0003] The packaging of liquid or paste-like materials presents certain unique challenges. Many of these materials, in particular, exhibit poor fluidity, leading to unstable material discharge and irregular loading, resulting in low production efficiency. Therefore, during the filling process, the liquid or paste must be maintained at a constant temperature to facilitate both discharge and filling. However, existing packaging machines with heating functions typically incorporate a separate heating device, resulting in a large footprint, numerous process nodes, and a complex structure. This increases packaging costs and is inconvenient for small businesses or those with low packaging volumes. Utility Model Content

[0022] In the description of this specification, the description of the term "as an alternative embodiment" means that the specific features, structures, materials or characteristics described in connection with this embodiment or example are included in at least one alternative embodiment or alternative example of the present utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0023] Combined with Figures 1 to 3 As shown, this embodiment provides a packaging machine, which includes: a frame 10, a material feeding assembly 20, a former 30, a hopper 40, a controller 50, and a packaging material feeding assembly 60. The material feeding assembly 20, the former 30, the hopper 40, the controller 50, and the packaging material feeding assembly 60 are all installed on the frame 10. The bottom of the frame 10 is provided with rollers to facilitate the movement of the entire packaging machine.

[0024] Based on the above embodiments, as an alternative embodiment, the barrel 40 and the material feeding assembly 20 are fixedly arranged on the upper part of the frame 10. The material feeding assembly 20 is arranged between the barrel 40 and the frame 10. The former 30 is fixedly arranged on the front side of the frame 10. The packaging material feeding assembly 60 is fixedly arranged on the left side of the frame 10. The controller 50 is fixedly arranged on the upper part of the packaging material feeding assembly 60.

[0025] Among them, the packaging material feeding assembly 60 is used to convey the packaging material into the former 30. The material feeding assembly 20 conveys the material from the barrel 40 into the former 30. The former 30 processes the packaging material into a packaging bag and at the same time encapsulates a quantitative material in the packaging bag. The controller 50 is used to control the actions of the packaging material feeding assembly 60 and the former 30.

[0026] Combined with Figure 2 As shown, the barrel 40 includes an inner barrel 41 and an outer barrel 42 arranged in a nested manner. The inner barrel 41 is used to store the material and is connected to the former 30 through the material feeding assembly 20. There is an interlayer for storing water between the inner barrel 41 and the outer barrel 42. A heater 43 is arranged in the interlayer. The heater 43 is used to heat the water in the interlayer. Water inlets 421 and water outlets 422 are provided on the side wall of the outer barrel 42. Both the water inlets 421 and the water outlets 422 are communicated with the interlayer. Thus, when the material in the inner barrel 41 needs to be heated, water can be injected into the interlayer through the water inlet 421, and the water in the interlayer can be heated by the heater 43. The material in the inner barrel 41 is indirectly heated and kept warm by the hot water in the interlayer, so that the material is heated and kept at a constant temperature, which is beneficial to controlling the temperature of the material in the inner barrel 41 in the best state. When the heating of the material in the inner barrel 41 is completed, the water in the interlayer can be discharged through the water outlet 422.

[0027] Based on the above embodiments, as an alternative embodiment, at least two heaters 43 are arranged in the interlayer, and both of the two heaters 43 are arranged close to the material feeding assembly 20. Preferably, the two heaters 43 are respectively arranged on both sides of the central axis of the barrel 40, and both of the two heaters 43 are electric heaters. Thus, the heating speed of the water in the interlayer can be increased, and the water can be heated more evenly, which is more convenient for controlling the temperature of the material in the inner barrel 41.

[0028] Based on the above embodiments, as an alternative embodiment, a connector 423 is further arranged on the side wall of the outer barrel 42. The connector 423 is connected to the heater 43. Thus, the heater 43 can be connected to an external circuit through the connector 423, so as to heat the water in the interlayer through the heater 43.

[0029] On the basis of the above embodiments, as an alternative embodiment, one end of the barrel 40 facing away from the material feeding assembly 20 has an opening 44. A barrel cover 45 for covering the opening 44 is provided on the barrel 40. A stirring assembly 46 is connected to the barrel cover 45. The stirring assembly 46 extends into the inner barrel 41 and is used for stirring the material in the inner barrel 41. Thus, by providing the opening 44, it is convenient to add materials into the inner barrel 41 and facilitate the operator to clean the inner barrel 41. By covering the opening 44 with the barrel cover 45, the evaporation of the water vapor of the material can be prevented, ensuring that the material concentration remains unchanged. By directly installing the stirring assembly 46 on the barrel cover 45, the installation space of the stirring assembly 46 is saved, which is beneficial to further reducing the space of the packaging machine.

[0030] On the basis of the above embodiments, as an alternative embodiment, the barrel cover 45 includes a first barrel cover 451 and a second barrel cover 452. The first barrel cover 451 is provided on the barrel 40. The second barrel cover 452 is hinged to the first barrel cover 451. The stirring assembly 46 passes through and is fixed on the first barrel cover 451. The second barrel cover 452 can be opened or cover the opening 44. Among them, the first barrel cover 451 can be detachably arranged on the barrel 40 by means of buckles or screws, etc., so as to facilitate the cleaning of the barrel 40 and the stirring assembly 46.

[0031] On the basis of the above embodiments, as an alternative embodiment, the stirring assembly 46 includes a stirring motor 461 and a stirring blade fan 462. The stirring motor 461 is installed on the first barrel cover 451. The drive shaft of the stirring motor 461 extends into the inner barrel 41. A stirring blade fan 462 is connected to the drive shaft of the stirring motor 461. The stirring blade fan 462 is located in the inner barrel 41. The stirring motor 461 drives the stirring blade fan 462 to rotate to stir the material in the inner barrel 41. Thus, through the action of the stirring assembly 46, the material in the inner barrel 41 can be stirred, which is beneficial to mixing the material in the inner barrel 41 evenly and making the material heat evenly.

[0032] On the basis of the above embodiments, as an alternative embodiment, the barrel 40 further includes a temperature sensor (not shown in the figure). The temperature sensor is arranged in the interlayer and is used for detecting the water temperature in the interlayer. The controller 50 is respectively connected to the heater 43 and the temperature sensor. The controller is used for controlling the opening or closing of the heater 43 according to the water temperature detected by the temperature sensor. Thus, when the water temperature in the interlayer is lower than the preset temperature, the controller 50 controls the heater 43 to turn on and automatically heats the water in the interlayer. When the water temperature in the interlayer is higher than the preset temperature, the controller 50 controls the heater 43 to stop heating. Through the controller 50 and the temperature sensor, the water in the interlayer can be maintained at the preset temperature, so that the material in the inner barrel 41 is heated evenly and remains in a constant temperature state.

[0033] It should be noted that, in this embodiment, the preset temperature is not further limited, and those skilled in the art can determine it according to the material in the inner cylinder 41 .

[0034] Based on the above embodiment, as an optional implementation, a liquid level indicator 424 is provided on the surface of the outer cylinder 42. The liquid level indicator 424 is used to display the water level within the interlayer. Thus, the liquid level sensor and the liquid level indicator 424 facilitate control of the water level within the interlayer. The liquid level indicator 424 can employ a conventional mechanical principle.

[0035] Based on the above embodiment, as an optional implementation, the material discharge assembly 20 includes a metering pump 21 and a discharge pipe 22. The inner cylinder 41 is connected to the input end of the metering pump 21, one end of the discharge pipe 22 is connected to the output end of the metering pump 21, and the other end of the discharge pipe 22 extends into the former 30. In this way, the material can be quantitatively delivered to the former 30, facilitating the former 30 to package the material.

[0036] The following combination Figures 1 to 3 , the working principle of the packaging machine provided in this embodiment is described:

[0037] Liquid material and paste material are added into the inner cylinder 41, the water inlet 421 is opened, the water outlet 422 is closed, water is injected into the interlayer through the water inlet 421, and the water in the interlayer is heated by the heater 43. While heating, the water temperature is monitored by the temperature sensor. When the water temperature reaches the preset temperature, the heater 43 stops heating to keep the material in the inner cylinder 41 at a constant temperature, and the stirring motor 461 drives the stirring blade 462 to rotate, stirring the material in the inner cylinder 41, so that the material in the inner cylinder 41 is mixed and heated evenly.

[0038] The metering pump 21 of the material discharge assembly 20 extracts the material from the inner cylinder 41 and then delivers the material to the forming device 30 through the discharge pipe 23;

[0039] The former 30 processes the packaging material into a packaging bag and simultaneously seals a fixed amount of material in the packaging bag.

[0040] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present utility model.
