Description

Technical Field

[0001] The present application relates to the technical field of plastic bag production, and in particular to a fully automatic plastic bag labeling device. Background Art

[0002] A labeling machine is a device that sticks rolls of self-adhesive paper labels on PCBs, products or specified packaging. A labeling machine is an indispensable part of modern packaging. The application range of labeling machines is extremely wide. After the production of plastic bags is completed, labels need to be attached to the packaging bags.

[0003] The above-mentioned existing technical solutions have the following defects: the existing chip placement machine can only label one side of the plastic bag, and cannot meet the needs of plastic bags that need to be labeled on both sides. Two chip placement machines are required to label both sides of the plastic bag respectively, which not only increases production costs but also reduces production efficiency. Utility Model Content

[0004] In order to improve the production efficiency of plastic bags that require double-sided labeling, the present application provides a fully automatic plastic bag labeling device.

[0005] The above technical objectives of this application are achieved through the following technical solutions:

[0006] The fully automatic plastic bag labeling device comprises a feeding mechanism, a first conveyor belt and a first labeling structure. The feeding mechanism is located at one end of the first conveyor belt, the first labeling structure is located above the first conveyor belt, and a clamping conveying structure is arranged on the side of the first conveyor belt away from the feeding structure. When the plastic bag moves to the clamping conveying structure, the clamping conveying structure clamps both sides of the plastic bag and drives the plastic bag to move forward. A second labeling structure is arranged below the clamping conveying structure.

[0007] By adopting the above scheme, when it is necessary to double-sidedly label the plastic bag, the plastic bag is placed at the feeding mechanism, the feeding mechanism places the plastic bag on the first conveyor belt, the first conveyor drives the plastic bag forward, the first labeling structure labels the upper side of the plastic bag, and then the first conveyor belt drives the plastic bag to move to the clamping conveying structure, the clamping conveying structure clamps the two sides of the plastic bag, and the clamping conveying structure drives the plastic bag forward. During the movement, the second labeling device labels the bottom of the plastic bag, thereby realizing double-sided labeling of the plastic bag, thereby improving the production efficiency of plastic bags that need double-sided labeling.

[0008] Optionally, a frame is provided on one side of the clamping and conveying structure, the clamping and conveying structure is connected to the frame, and the second labeling structure is connected to the frame.

[0009] By adopting the above solution, the frame provides support for the clamping and conveying structure and the second labeling structure.

[0010] Optionally, the frame is connected with a driving structure. The clamping and conveying structure includes an upper clamping structure and a lower clamping structure. The upper clamping structure includes an upper driving pulley group, an upper driven pulley group and an upper conveyor belt. The upper driving pulley group includes an upper driving pulley rod and an upper driving pulley. The upper driving pulley rod is rotatably connected to the frame and is connected to the driving structure. There are two upper driving pulleys, and the two upper driving pulleys are fixedly connected to the upper driving pulley rod near both ends. The upper driven pulley group includes an upper driven pulley rod and an upper driven pulley. The upper driven pulley rod is rotatably connected to the bracket. There are two upper driven pulleys, and the two upper driven pulleys are respectively fixedly connected to the upper driven pulley rod near both ends. The upper driving pulley and the upper driven pulley are driven by the upper conveyor belt, and a plurality of upper clamping plates are arranged on the outer side of the upper conveyor belt.

[0011] By adopting the above scheme, when the plastic bag moves to the clamping structure, the upper driving pulley drives the upper conveyor belt to move, thereby driving the upper clamping plate to move, so that the upper clamping plate and the lower clamping structure clamp both sides of the plastic bag, and the plastic bag moves forward with the upper conveyor belt, thus realizing clamping both sides of the plastic bag and driving the plastic bag to move forward.

[0012] Optionally, the lower clamping structure includes a lower driving pulley group, a lower driven pulley group and a lower conveyor belt. The lower driving pulley group includes a lower driving pulley rod and a lower driving pulley. The lower driving pulley rod is rotatably connected to the frame and is connected to the driving structure. There are two lower driving pulleys, and the two lower driving pulleys are fixedly connected to the lower driving pulley rod near both ends. The lower driven pulley group includes a lower driven pulley rod and a lower driven pulley. The lower driven pulley rod is rotatably connected to the bracket. There are two lower driven pulleys, and the two lower driven pulleys are respectively fixedly connected to the lower driven pulley rod near both ends. The lower driving pulley and the lower driven pulley are driven by the lower conveyor belt, and a plurality of lower clamping plates are arranged on the outer side of the lower conveyor belt.

[0013] By adopting the above scheme, when the plastic bag moves to the clamping structure, the upper driving pulley drives the upper conveyor belt pulley to move, and the lower driving pulley drives the lower conveyor belt pulley to move, so that the upper clamping plate and the lower clamping plate clamp the upper and lower surfaces of the plastic bag. At the same time, the upper conveyor belt and the lower conveyor belt drive the upper clamping plate and the lower clamping plate to move forward respectively, thereby driving the plastic bag to move forward, and there is enough space between the two lower conveyor belts for the second labeling structure to label the lower part of the plastic bag. The second labeling structure labels the lower part of the plastic bag, thus realizing labeling the lower surface of the plastic bag.

[0014] Optionally, an upper telescopic rod is arranged between the upper clamping plate and the upper conveyor belt. The upper telescopic rod includes an upper telescopic inner rod and an upper telescopic outer tube. The upper telescopic inner rod is connected to the upper conveyor belt, the upper telescopic outer tube is fixedly connected to the upper clamping plate, the upper telescopic inner rod is slidably connected in the upper telescopic outer tube, and an upper spring is arranged in the upper telescopic outer tube.

[0015] By adopting the above solution, when the upper clamping plate and the lower clamping plate are clamped together, the upper spring is in a compressed state, and the upper spring applies a downward force to the upper clamping plate, thereby clamping the upper clamping plate and the lower clamping plate more tightly.

[0016] Optionally, the frame is connected to a support plate, and when the second labeling structure labels the plastic bag, the plastic bag rests against the lower surface of the support plate.

[0017] By adopting the above solution, since plastic is supported by flexible materials, when labeling the lower surface of the plastic bag, the plastic bag may be suspended in the air, causing the plastic bag to deform, resulting in loose labeling. Therefore, a support plate is provided to support the upper surface of the plastic bag to avoid deformation of the plastic bag when labeling the lower surface of the plastic bag.

[0018] Optionally, the upper driving wheel rod is fixedly connected to an upper gear, the lower driving wheel rod is fixedly connected to a lower fixed wheel rod, the upper gear is meshed with the lower gear, the driving structure includes a driving motor, the output shaft of the driving motor is connected to a main gear, and the main gear is meshed with the upper gear.

[0019] By adopting the above scheme, the driving motor rotates to drive the main gear to rotate, the main gear drives the upper gear to rotate, and the upper gear drives the lower gear to rotate, thereby realizing the synchronous movement of the upper driving wheel rod and the lower driving wheel rod, that is, the synchronous movement of the upper transmission pulley and the lower transmission pulley.

[0020] Optionally, a transition conveyor belt is arranged at one end of the first conveyor belt away from the feeding mechanism, a pulley on one side of the transition conveyor belt is fixedly connected to the lower driving wheel rod, and the width of the transition conveyor belt is smaller than the distance between the two lower driving pulleys.

[0021] By adopting the above solution, since there are gaps between the first conveyor belt and the clamping conveyor structure, the plastic bag may bend when passing through these gaps, resulting in failure of labeling on the lower surface of the plastic bag. Therefore, a transition conveyor belt is provided. When the plastic bag reaches between the conveying structure and the clamping conveying structure, the transition conveyor belt supports the plastic bag, thereby preventing the plastic bag from sinking.

[0022] In summary, this application has the following technical effects:

[0023] 1. Label the lower surface of the plastic bag by setting up a clamping and conveying structure and a second labeling structure;

[0024] 2. The upper and lower splints are clamped tighter by setting an upper telescopic rod;

[0025] 3. The upper surface of the plastic bag is supported by setting a support plate, so that the label on the lower surface of the plastic bag can be more tightly attached. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] Refer to Figure 1The fully automatic plastic bag labeling device comprises a feeding mechanism 1, a first conveyor belt 2 and a first labeling structure 3. The feeding mechanism 1 is located at one end of the first conveyor belt 2, the first labeling structure 3 is located above the first conveyor belt 2, and a clamping conveying structure is arranged on the side of the first conveyor belt 2 away from the feeding structure. When the plastic bag moves to the clamping conveying structure, the clamping conveying structure clamps both sides of the plastic bag and drives the plastic bag to move forward. A second labeling structure 4 is arranged below the clamping conveying structure. When double-sided labeling of a plastic bag is required, the plastic bag is placed at the feeding mechanism 1, which places the plastic bag on the first conveyor belt 2. The first conveyor belt 2 drives the plastic bag forward, and the first labeling structure 3 labels the upper side of the plastic bag. Then, the first conveyor belt 2 drives the plastic bag to move to the clamping conveying structure, which clamps both sides of the plastic bag, and the clamping conveying structure drives the plastic bag forward. During the movement, the second labeling device labels the bottom of the plastic bag, thereby achieving double-sided labeling of the plastic bag, thereby improving the production efficiency of plastic bags that require double-sided labeling.

[0035] Reference Figure 1 The feeding mechanism 1, the conveyor belt and the first labeling structure 3 are all existing structures. The second labeling structure 4 is the same as the first labeling structure 3, and the second labeling structure 4 is inverted under the clamping and conveying structure.

[0036] Figure 2 , Figure 3 and Figure 5, a frame body 5 is provided on one side of the clamping and conveying structure. The clamping and conveying structure is connected to the frame body 5, and the second labeling structure 4 is connected to the frame body 5. The frame body 5 provides support for the clamping and conveying structure and the second labeling structure 4. The frame body 5 is connected with a driving structure. The clamping and conveying structure includes an upper clamping structure 6 and a lower clamping structure 7. The upper clamping structure 6 includes an upper driving pulley group 61, an upper driven pulley group 62 and an upper conveyor belt 63. The upper driving pulley group 61 includes an upper driving pulley rod 611 and an upper driving belt pulley 612. The upper driving pulley rod 611 is rotatably connected to the frame body 5 and is connected to the driving structure. There are two upper driving belt pulleys 612, and the two upper driving belt pulleys 612 are fixedly connected to the upper driving pulley rod 611 near both ends. The upper driven pulley group 62 includes an upper driven pulley rod 621 and an upper driven belt pulley 622. The upper driven pulley rod 621 is rotatably connected to the bracket. There are two upper driven belt pulleys 622, and the two upper driven belt pulleys 622 are respectively fixedly connected to the upper driven belt pulley 622 near both ends. The upper driving belt pulley 612 and the upper driven belt pulley 622 are driven by the upper conveyor belt 63, and a plurality of upper clamping plates 631 are arranged on the outer side of the upper conveyor belt 63. An upper telescopic rod 8 is arranged between the upper clamping plate 631 and the upper conveyor belt 63. The upper telescopic rod 8 includes an upper telescopic inner rod 82 and an upper telescopic outer tube 81. The upper telescopic inner rod 82 is connected to the upper conveyor belt 63, the upper telescopic outer tube 81 is fixedly connected to the upper clamping plate 631, the upper telescopic inner rod 82 is slidably connected in the upper telescopic outer tube 81, and an upper spring 83 is arranged in the upper telescopic outer tube 81.

[0037] Refer to Figure 4 , the lower clamping structure 7 includes a lower driving pulley group 71, a lower driven pulley group 72 and a lower conveyor belt 73. The lower driving pulley group 71 includes a lower driving pulley rod 711 and a lower driving belt pulley 712. The lower driving pulley rod 711 is rotatably connected to the frame body 5 and is connected to the driving structure. There are two lower driving belt pulleys 712, and the two lower driving belt pulleys 712 are fixedly connected to the lower driving pulley rod 711 near both ends. The lower driven pulley group 72 includes a lower driven pulley rod 721 and a lower driven belt pulley 722. The lower driven pulley rod 721 is rotatably connected to the bracket. There are two lower driven belt pulleys 722, and the two lower driven belt pulleys 722 are respectively fixedly connected to the lower driven belt pulley 722 near both ends. The lower driving belt pulley 712 and the lower driven belt pulley 722 are driven by the lower conveyor belt 73, and a plurality of lower clamping plates 731 are arranged on the outer side of the lower conveyor belt 73.

[0038] Refer to Figure 3 and Figure 4When the plastic bag moves to the clamping structure, the upper driving pulley 612 drives the upper conveyor belt 63 to move, and the lower driving pulley 712 drives the lower conveyor belt 73 to move, so that the upper clamping plate 631 and the lower clamping plate 731 clamp the upper and lower surfaces of the plastic bag. At this time, the upper spring 83 is in a compressed state, and the upper spring 83 gives a downward force to the upper clamping plate 631, so that the upper clamping plate 631 and the lower clamping plate 731 are clamped more tightly. At the same time, the upper conveyor belt 63 and the lower conveyor belt 73 drive the upper clamping plate 631 and the lower clamping plate 731 to move forward respectively, so as to drive the plastic bag to move forward. And there is enough space between the two lower conveyor belts 73 for the second labeling structure 4 to label the lower part of the plastic bag. The second labeling structure 4 labels the lower part of the plastic bag, so as to realize labeling the lower surface of the plastic bag.

[0039] Refer to Figure 3 The frame body 5 is connected with a support plate 51. When the second labeling structure 4 labels the plastic bag, the plastic bag abuts against the lower surface of the support plate 51. Since the plastic is supported by a flexible material, when labeling the lower surface of the plastic bag, the plastic bag may deform when it is suspended, resulting in insecure labeling. Therefore, the support plate 51 is provided to support the upper surface of the plastic bag to prevent the plastic bag from deforming when labeling the lower surface of the plastic bag.

[0040] Refer to Figure 6 The upper driving wheel rod 611 is fixedly connected with an upper gear 92, the lower driving wheel rod 711 is fixedly connected with a lower fixed wheel rod, the upper gear 92 meshes with the lower gear 93, and the driving structure includes a driving motor 9. The output shaft of the driving motor 9 is connected with a main gear 91, and the main gear 91 meshes with the upper gear 92. When the driving motor 9 rotates, it drives the main gear 91 to rotate. The main gear 91 drives the upper gear 92 to rotate, and the upper gear 92 drives the lower gear 93 to rotate, so as to realize the synchronous movement of the upper driving wheel rod 611 and the lower driving wheel rod 711, that is, the synchronous movement of the upper conveyor belt pulley and the lower conveyor belt pulley.

[0041] Refer to Figure 1 At one end of the first conveyor belt 2 away from the feeding mechanism 1, there is a transition conveyor belt 10. One side pulley of the transition conveyor belt 10 is fixedly connected with the lower driving wheel rod 711, and the width of the transition conveyor belt 10 is smaller than the distance between the two lower driving pulleys 712. Since there is a gap between the first conveyor belt 2 and the clamping conveyor structure, when the plastic bag passes through these gaps, it may bend, resulting in failure of labeling the lower surface of the plastic bag. Therefore, the transition conveyor belt 10 is provided. When the plastic bag reaches between the conveyor structure and the clamping conveyor structure, the transition conveyor belt 10 supports the plastic bag, so as to prevent the plastic bag from sinking.

[0042] The specific implementation principle of this application is as follows: When double-sided labeling of plastic bags is required, place the plastic bags at the feeding mechanism 1. The feeding mechanism 1 places the plastic bags on the first conveyor belt 2. The first conveyor belt 2 moves the plastic bags forward. The first labeling structure 3 labels the upper side of the plastic bags. Subsequently, the first conveyor belt 2 drives the plastic bags to move onto the transition conveyor belt 10. The plastic bags move on the transition conveyor belt 10. At the same time, the upper clamping plate 631 and the lower clamping plate 731 clamp both sides of the plastic bags. The drive motor 9 drives the upper driving wheel and the lower driving wheel to move, thereby driving the upper conveyor belt 63 and the lower conveyor belt 73 to move, and then driving the plastic bags to move forward. During the movement, the second labeling device labels the lower side of the plastic bags. The support plate 51 restricts the plastic bags from deforming, so that the labeling is more smooth, thereby realizing double-sided labeling of plastic bags, and thus improving the production efficiency of plastic bags that require double-sided labeling.
