Description

Technical Field

[0001] The utility model relates to the technical field of blueberry packaging, in particular to a punching and labeling device for blueberry heat shrink film packaging. Background Art

[0002] At present, fresh blueberries are generally sold in PET boxes during transportation, or the PET boxes are placed in cartons with an opening at the top, and the PET boxes or cartons are sealed with heat shrink film. After heat shrink film packaging, the temperature inside the carton is high, and blueberries are generally transported in a cold chain with a cold chain temperature of 0-4℃. When low-temperature blueberries encounter hot and humid air, the hot and humid air will condense on the surface of the low-temperature blueberries, causing condensation on the surface and even condensing into water, creating opportunities for the reproduction of microorganisms such as mold, which is also the main cause of blueberry rot. Therefore, after blueberries are packaged, holes need to be punched on the surface of the heat shrink film to release the hot air in the package, but the punching destroys the integrity and sealing of the package. In the later stage of transportation and terminal retail, the packaging is open due to the punching, and condensation will occur when there is a temperature difference. At the same time, external pathogens and impurities will inevitably invade, so the holes will be covered by labeling to avoid the above situation. At present, manual punching and labeling are mainly used, which is inefficient and needs to be improved. Utility Model Content

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0020] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] like Figure 1 As shown, the punching and labeling device for heat shrink film packaging of blueberries in this embodiment includes a frame 1, a conveyor belt 2, a punching mechanism 3 and a labeling mechanism 4. The conveyor belt 2 is arranged on the frame 1 in the horizontal direction. The conveyor belt 2 can adopt a belt or chain conveyor commonly used in the art, which is used to transport blueberry packaging cartons (or PET boxes) to the punching mechanism 3 and the labeling mechanism 4; the punching mechanism 3 and the labeling mechanism 4 are arranged side by side on the frame 1 in the longitudinal direction and are located on one side of the conveyor belt 2, and are respectively used to punch and label the heat shrink film on the outside of the package.

[0022] The punching mechanism 3 includes a first driving unit 31 and a heating rod 32. The first driving unit 31 is arranged on the frame 1 through a first bracket 33, and the heating rod 32 is arranged below the first driving unit 31. The first driving unit 31 drives the heating rod 32 to move downward, thereby hot-stamping air holes on the surface of the heat shrink film; wherein, the first driving unit 31 can adopt a linear driving method such as a cylinder, an oil pipe, an electric push rod, etc., and the heating rod 32 can adopt a structure such as an electric heating tube, an electric soldering iron, etc.

[0023] like Figure 2As shown, the labeling mechanism 4 includes a label peeler and a label applicator, and the label peeler and the label applicator are arranged on the frame 1 through a second bracket 41.

[0024] The label peeler includes a base 42, a feeding roller 43, a receiving roller 44 and a peeling plate 45. The base 42 is fixedly arranged on the top of the second bracket 41. The feeding roller 43 and the receiving roller 44 are rotatably arranged on the base 42 respectively, wherein the feeding roller 43 is a driven roller and the receiving roller 44 is an active roller, and the rear side thereof is driven to operate by a motor (not shown in the figure). The peeling plate 45 is arranged below the receiving roller 44. After the label paper comes out of the feeding roller 43, it is wound around the receiving roller 44 through the peeling plate 45.

[0025] At least one positioning roller 46 is further provided on the lower side of the peeling plate 45 . The positioning roller 46 enables the label paper to slide along the bottom surface of the peeling plate 45 . A peeling portion 47 with an acute angle structure is provided at the front end of the peeling plate 45 .

[0026] The labeler includes a rotating unit 48 , a second driving unit 49 and a suction cup 410 . The rotating unit 48 is arranged on the second bracket 41 through a linear module. The second driving unit 49 is transmission-connected to the rotating unit 48 . The suction cup 410 is arranged at the front end of the second driving unit 49 .

[0027] The linear module includes a screw 411, an auxiliary slide 412 and a third drive unit 413. The screw 411 is longitudinally arranged between the second bracket 41 and the frame 1. The auxiliary slide 412 and the screw 411 are arranged side by side. The third drive unit 413 is arranged on the top of the screw 411. The rotating unit 48 is connected to the screw 411 in transmission.

[0028] The rotating unit 48 may adopt a rotating drive method such as a rotating cylinder or a motor, the second driving unit 49 may adopt a linear drive method such as a cylinder, an oil pipe, or an electric push rod, and the third driving unit 413 may adopt a driving method such as a motor.

[0029] like Figure 3 As shown, during labeling, the receiving roller 44 drives the label roll to rotate. When the roll reaches the peeling portion 47 at the front end of the peeling plate 45, the base paper 5 suddenly bends to the back side, and the label paper 6 continues to move forward, thereby separating the base paper 5 from the label paper 6. At the same time, the rotating unit 48 drives the second driving unit 49 and the suction cup 410 to approach the label paper 6, and the peeled label paper 6 is sucked by the suction cup 410.

[0030] Then the rotating unit 48 drives the suction cup 410 to rotate to the lower side, and the linear module drives the labeler to move downward as a whole, so that the label paper 6 is attached to the hole on the heat shrink film, thereby sealing the hole; after labeling, the suction cup 410 releases the label paper 6, and the rotating unit 48 drives the second driving unit 49 and the suction cup 410 to rotate upward again, and at the same time the linear module drives the labeler to move upward as a whole, preparing for the next action.

[0031] After the package is labeled and sealed, the humidity inside the package can be guaranteed, keeping the blueberries in a sealed environment, reducing the loss of water in the blueberries, and reducing wilting and shrinking during storage.

[0032] It should be noted that a certain time interval can be set between the punching action and the labeling action to ensure that the heat inside the package is fully released, and the movement of the package can be accurately controlled by cooperating with sensors such as proximity switches to ensure that the punching and labeling positions match; the above technical solution can be implemented using conventional technical means in this field, so it will not be repeated here.

[0033] In summary, the utility model uses the punching mechanism 3 to punch holes in the heat shrink film on the outside of the blueberry package to release the internal heat, and uses the labeling mechanism 4 to label the heat shrink film to seal the punched holes, thereby achieving sealing of the package. Compared with the traditional manual method, the punching and sealing efficiency is significantly improved.

[0034] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.
