Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to a labeling machine for packaging wood ear fungus. Background Technology

[0002] After processing, the wood ear mushrooms are packaged in bags for transportation and sale. To display product information, labels need to be affixed to the packaging bags.

[0003] A search revealed that the prior art discloses a labeling machine (publication number: CN218022661U), which includes a conveyor belt, a labeling machine body mounted on the side wall of the conveyor belt, a label pressing device provided on the side wall of the conveyor belt, a mounting frame fixedly connected to the side wall of the conveyor belt, a sliding plate slidably inserted in the mounting frame, a rotating rod rotatably connected in the sliding plate, a pressure roller slidably connected to the arc surface of the rotating rod, an actuator motor fixedly connected to the side of the sliding plate away from the pressure roller, and the output end of the actuator motor fixedly connected to the rotating rod.

[0004] In existing technologies, after labeling, the label and packaging are squeezed by pressure rollers to ensure the label is secure. However, for packaging bags containing dried wood ear mushrooms, the packaging bags themselves are relatively soft, and the wood ear mushrooms inside the packaging bags are easily damaged and broken after being squeezed by the rollers, which affects the quality of the product. There is room for optimization in the way the label is squeezed during the labeling process.

[0005] Therefore, we propose a labeling machine for packaging wood ear mushrooms. Utility Model Content

[0006] The present invention mainly addresses the technical problem that the aforementioned pressing labels easily crush the wood ear mushrooms, and provides a labeling machine for wood ear mushroom packaging.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a labeling machine for packaging wood ear mushrooms, comprising:

[0008] The frame has a conveyor belt at the top for conveying and a take-up roller at the top for taking up the labels.

[0009] A label pressing structure, installed above the frame, is used to press labels. The label pressing structure includes a push rod and a mounting base. The push rod is fixedly installed above the frame, and the mounting base is fixedly installed at the lower end of the output shaft of the push rod.

[0010] A pressing assembly, located at the bottom of the mounting base, is used for bonding labels and packaging bags. The pressing assembly includes an adsorption hood, a baffle, and an air extraction pipe. The adsorption hood is fixedly installed to the mounting base, the baffle is elastically connected to the adsorption hood, and the air extraction pipe is fixedly installed to the adsorption hood. A gap is left between the baffle and the adsorption hood, and the air extraction pipe can suck air from the gap.

[0011] In a preferred embodiment of this utility model, the adsorption hood forms a rectangular box with an open bottom, the baffle is a rectangular plate, the size of the baffle is smaller than the internal size of the adsorption hood, and a gap is formed between the side wall of the baffle and the inner wall of the adsorption hood.

[0012] In a preferred embodiment of this utility model, the baffle is provided with integrally formed sliders at both ends, and the inner wall of the adsorption cover is provided with a groove adapted to the slider, and the slider is slidably disposed in the groove.

[0013] In a preferred embodiment of this utility model, the suction pipe is fixedly installed on the top of the adsorption hood, with a clearance between the top surface of the baffle and the inner top surface of the adsorption hood, and the lower end of the suction pipe extends into the cavity of the adsorption hood and is flush with the inner top surface of the adsorption hood.

[0014] In a preferred embodiment of this utility model, the pressing assembly further includes a heating rod, and the top of the baffle is provided with a plurality of slots for installing the heating rod, and the heating rod is fixedly installed in the slots.

[0015] In a preferred embodiment of this utility model, the pressing assembly further includes springs, and several springs are fixedly installed on the top of the baffle. The upper end of the springs can abut against the deformation of the inner top surface of the adsorption cover.

[0016] In a preferred embodiment of this utility model, the reed is a rectangular plate, and multiple reeds are divided into two groups, with the two groups of reeds being symmetrical and arranged in a figure-eight pattern.

[0017] This utility model provides a labeling machine for packaging wood ear mushrooms. It has the following beneficial effects:

[0018] 1. This labeling machine for packaging wood ear mushrooms involves connecting an air extraction pipe to a fan, which draws air into the adsorption hood cavity. When the push rod lowers the mounting base, the lower end of the adsorption hood contacts the packaging bag, with the label facing the lower port of the adsorption hood. Consequently, the packaging bag is adsorbed onto the lower end of the adsorption hood. A flexible baffle abuts against the label and the packaging bag at the label application position, achieving compression and adhesion between the label and the packaging bag. This ensures a firm label adhesion while significantly improving the protection of the wood ear mushrooms, making them less prone to breakage due to labeling.

[0019] 2. This labeling machine for packaging wood ear mushrooms uses an electric heating rod connected to a power source. When the label is attached to the bottom of the baffle, the heating rod heats the baffle, promoting adhesion between the label and the packaging bag and improving the adhesion strength.

[0020] 3. This labeling machine for wood ear mushroom packaging uses a spring made of spring steel to push a baffle downward. The baffle drives a slider to slide in a groove on the inner wall of the adsorption hood, so that after the packaging bag is adsorbed at the lower end of the adsorption hood, the baffle can support the packaging bag and ensure that the label and the packaging bag can stick together under the action of air pressure difference. The overall structure is simple and the labeling effect is good. Attached Figure Description

[0027] A labeling machine for packaging wood ear mushrooms, such as Figure 1 and Figure 2 As shown, it includes:

[0028] The frame 10 has a conveyor belt 11 on its top for conveying and a take-up roller 12 on its top for taking up the labels. In this solution, there are at least three take-up rollers 12. One take-up roller 12 is used to place the label, another take-up roller 12 is used to take up the base tape of the label, and the last take-up roller 12 is used to take up the residue at the edge of the label after labeling. The conveyor belt 11 and the take-up roller 12 can be driven by a motor. Since this is known prior art, it will not be described in detail here.

[0029] like Figure 2 and Figure 3 As shown, the label pressing structure is set above the frame 10 for pressing labels. The label pressing structure includes a push rod 13 and a mounting base 14. The push rod 13 is fixedly installed above the frame 10, and the mounting base 14 is fixedly installed at the lower end of the output shaft of the push rod 13.

[0030] like Figure 3 , Figure 4 and Figure 5As shown, the pressing assembly, located at the bottom of the mounting base 14, is used for bonding labels and packaging bags. The pressing assembly includes an adsorption hood 20, a baffle 21, and an extraction pipe 22. The adsorption hood 20 is fixedly installed to the mounting base 14, the baffle 21 is elastically connected to the adsorption hood 20, and the extraction pipe 22 is fixedly installed to the adsorption hood 20. A gap is left between the baffle 21 and the adsorption hood 20, allowing the extraction pipe 22 to draw air from the gap. The adsorption hood 20 forms a rectangular box with an open bottom, and the baffle 21 is a rectangular plate. The size of 1 is smaller than the internal size of the adsorption hood 20. A gap is formed between the side wall of the baffle 21 and the inner wall of the adsorption hood 20. The two ends of the baffle 21 are provided with integrally formed sliders. The inner wall of the adsorption hood 20 is provided with a sliding groove adapted to the slider. The slider is slidably disposed in the sliding groove. The suction pipe 22 is fixedly installed on the top of the adsorption hood 20. There is a gap between the top surface of the baffle 21 and the inner top surface of the adsorption hood 20. The lower end of the suction pipe 22 extends into the cavity of the adsorption hood 20 and is flush with the inner top surface of the adsorption hood 20.

[0031] In this solution, since the packaging bag contains dried wood ear mushrooms, which are quite brittle, pressing the label after application can easily damage the mushrooms and affect the product quality. By connecting the suction pipe 22 to a fan, the suction pipe 22 draws air into the cavity of the adsorption hood 20. When the push rod 13 pushes the mounting base 14 down, the lower end of the adsorption hood 20 contacts the packaging bag, with the label facing the lower port of the adsorption hood 20. The packaging bag is then adsorbed onto the lower end of the adsorption hood 20. The elastically connected baffle 21 abuts against the label and the packaging bag at the label application position, achieving compression and adhesion between the label and the packaging bag. This greatly improves the protection of the wood ear mushrooms while ensuring a firm label adhesion, making it less likely for the mushrooms to break due to labeling.

[0032] like Figure 5 As shown, the pressing assembly also includes a heating rod 23. The top of the baffle 21 has several slots for installing the heating rod 23. The heating rod 23 is fixedly installed in the slots. By setting the heating rod 23 and connecting it to a power source, when the label is attached to the bottom of the baffle 21, the baffle 21, which is heated by the heating rod 23, heats the label and promotes the adhesion between the label and the packaging bag.

[0033] like Figure 5 As shown, the pressing assembly also includes springs 24. Several springs 24 are fixedly installed on the top of the baffle 21. The upper end of the springs 24 can abut against the deformation of the inner top surface of the adsorption cover 20. The springs 24 are rectangular plates. The multiple springs 24 are divided into two groups. The two groups of springs 24 are symmetrical and distributed in a figure-eight pattern. By setting the springs 24, the baffle 21 is pushed down by the spring steel springs 24. The baffle 21 drives the slider to slide in the groove on the inner wall of the adsorption cover 20, so that after the packaging bag is adsorbed at the lower port of the adsorption cover 20, the baffle 21 can support the packaging bag and ensure that the label and the packaging bag can be bonded under the action of air pressure difference. The overall structure is simple and the labeling effect is good.

[0034] The working principle of this utility model is as follows: The suction pipe 22 is connected to a fan, and the suction pipe 22 draws air into the cavity of the adsorption cover 20. When the push rod 13 pushes the mounting base 14 down, the lower end of the adsorption cover 20 contacts the packaging bag. The label is directly opposite the lower port of the adsorption cover 20, and the packaging bag is then adsorbed at the lower end of the adsorption cover 20. The elastically connected baffle 21 abuts against the label and the packaging bag at the label affixing position, achieving compression and adhesion between the label and the packaging bag. The heating rod 23 is connected to a power source. When the label is attached to the bottom of the baffle 21, the baffle 21, heated by the heating rod 23, heats the label. The spring sheet 24 made of spring steel pushes the baffle 21 down. The baffle 21 drives the slider to slide in the groove on the inner wall of the adsorption cover 20, so that after the packaging bag is adsorbed at the lower port of the adsorption cover 20, the baffle 21 can support the packaging bag and ensure that the label and the packaging bag can be bonded under the action of air pressure difference.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
