Description

Technical Field

[0001] The invention relates to the technical field of handle threading machines, in particular to a carton handle threading machine. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. Cartons need to use a handle threading machine to install handles. At present, domestic carton handle threading machines have always been manually operated, which is inefficient and labor-intensive. Large factories usually use fully automatic non-woven handle threading machines to install non-woven handles on cartons, but this threading machine will have the following problems when used:

[0003] When the handle threading machine is processing, the carton board is transported on the conveying mechanism, and passes through the corresponding processing stations in sequence, and punching, gluing and threading are performed step by step. However, this method first applies glue on the carton board, and then the handle is loaded and threaded. This may easily cause uneven application of the adhesive during gluing and the handle may be offset when it is loaded. The handle cannot be completely bonded to the corresponding position on the carton, causing debonding and affecting production quality. Summary of the invention

[0004] The purpose of the present invention is to provide a carton handle threading machine, which aims to solve the problem that the existing handle threading machines perform punching, glue brushing and tape threading in steps during processing, which easily causes uneven application of adhesive during glue brushing and the handle cannot be completely glued to the corresponding position on the carton when the handle is offset when being loaded, causing debonding and affecting production quality.

[0007] A further technical solution of the present invention is that an upwardly inclined moving groove is opened on the front and rear walls of the glue chamber, and the glue brush roller is movably installed in the moving groove through a rotating shaft. When the handle is inserted into the handle slot, the handle can squeeze the glue brush roller to make it move along the moving groove. At the same time, the glue brush roller will be pressed tightly against the handle due to its own gravity.

[0008] A further technical solution of the present invention is that it includes a cam block, a rubber brush roller and a rotating shaft that are rotatably installed in the punching head, one end of the cam block extends into the handle slot, the glue chamber is arranged in the cam block, the rubber brush roller is rotatably installed in the glue chamber through the rotating shaft, and one end face of the rubber brush roller protrudes from the upper end face or the lower end face of the cam block, so that when the handle is inserted into the handle slot, the end of the cam block located in the handle slot is squeezed and rotated, the rubber brush roller contacts the handle, and the adhesive in the glue chamber is smeared on the handle.

[0009] A further technical solution of the present invention is that the handle misalignment driving device is a screw rod rotatably mounted on the frame, the screw rod is connected to the punching head, and then drives the punching head to move horizontally.

[0030] like Figure 1 As shown, a paper hole is opened on the carton board 8, and the two handle ends 82a of the handle 82 are respectively bonded to the edge positions of the paper hole 81. In view of the problem that the existing handle 82 threading machine performs punching, glue brushing and tape threading in steps during processing, it is easy to cause uneven application of adhesive during glue brushing and the handle 82 cannot be completely bonded to the corresponding position on the carton when the material is offset, resulting in debonding and affecting the production quality. The following solution is proposed to solve this problem.

[0031] like Figure 1-4 As shown, a carton handle threading machine includes a frame 40, on which a conveying structure 41, a punching head 10 and a handle loading mechanism are arranged, wherein the punching head 10 is installed on the frame 40 in a liftable manner, and a gluing mechanism 30 for applying adhesive to the handle 82 is arranged in the punching head 10, and a handle misalignment driving device is also arranged on the frame 40, which can drive the punching head 10 to reciprocate in the horizontal direction, that is, the punching head 10 can move in the same direction or the opposite direction to the conveying direction of the conveying structure 41, and also includes a rolling mechanism, when the handle 82 is bonded to the carton board 8, the handle 82 is pressed tightly against the carton board 8.

[0032] Among them, when the conveying structure 41 conveys the carton board 8 to the punching station, the punching head 10 punches the carton board 8. When the carton board 8 is punched, the handle loading mechanism located below the carton board 8 conveys the handle 82 to the bottom of the punching head 10, and lifts the handle 82, so that the two handle ends 82a of the handle 82 pass through the paper holes 81 on the carton board 8 respectively, and enter the gluing mechanism 30. When the adhesive is applied to the handle 82, the two ends of the handle 82 are driven by the handle misalignment driving device to move toward each other, so that the two handle ends 82a of the handle 82 are misaligned with the paper holes 81 on the carton board 8, and at the same time, the rolling mechanism is cooperated so that the two handle ends 82a of the handle 82 can be pressed and bonded to the edge of the paper hole 81 of the carton board 8.

[0033] refer to Figure 2 and Figure 3 As shown, the conveying structure 41 is two conveyor belts distributed at intervals, and a punching channel 41a is formed in the middle of the conveyor belts to ensure that the punching head 10 can pass through the carton board 8 to complete the punching operation, so that the waste generated falls from the punching channel 41a. At the same time, the holes on the carton board 8 are located on the punching channel 41a, so that the two handle ends 82a of the handle 82 can pass through the paper holes 81 on the carton board 8 to complete the loading operation of the handle 82.

[0034] like Figure 4 and Fig. 9 As shown, the handle loading mechanism is arranged on the frame 40 and corresponds to the position of the punching channel 41a, and specifically includes a moving frame 50 slidably connected to the frame 40, and an electric roller is installed at the bottom of the moving frame 50 to ensure that it can move on the frame 40 in the same direction or the opposite direction along the conveying direction of the conveying structure 41, and a U-shaped loading tray 51 is arranged on the inner side of the moving frame 50, and a lifting component 52 is installed on the moving frame 50 to drive the loading tray 51 to rise and provide a handle 82 for the carton board 8, and the lifting component 52 is an electric telescopic rod; when in use: the non-woven fabric handle 82 has a certain plasticity, and it is pressed on the loading tray 51 to form a U-shaped structure. After punching is completed, the moving frame 50 moves to the bottom of the punching head 10, and the lifting component 52 drives the loading tray 51 to rise, and the two handle ends 82a of the handle 82 respectively pass through the paper holes 81 on the carton board, and the handle 82 is sent to the gluing mechanism 30 in the punching head 10 of the handle 82, and the adhesive is applied to the handle 82.

[0035] refer to Figure 4The first embodiment of the gluing mechanism 30 includes a handle slot 11 provided in the punching head 10. Both ends of the handle 82 pass through the carton board 8 and are inserted into the handle slot 11. A glue chamber 31 is provided on one side of the handle slot 11. A mounting hole is provided at a position of the glue chamber 31 near the bottom of the punching head 10, and the mounting hole is connected to the handle slot 11. A glue brushing roller 32 is rotatably installed in the mounting hole through a rotating shaft 34. A portion of the glue brushing roller 32 extends into the handle slot 11. The glue brushing roller 32 is provided with a plurality of adhesives. The other part of the roller 32 is located in the glue chamber 31. The glue brush roller 32 is provided with flexible bristles, which contact the inner wall of the mounting hole to form a sealed effect, so that the adhesive in the glue chamber 31 will not overflow. The flexible bristles can be sponge, cotton, etc.; when the handle 82 is inserted into the handle slot 11, it contacts the glue brush roller 32 and drives the glue brush roller 32 to rotate. The glue brush roller 32 brings out the adhesive in the glue chamber 31 and smears it on the handle 82, completing the gluing process of the handle 82.

[0036] In the above embodiment, the distance between the glue brush roller 32 and the side wall opposite to the glue brush roller 32 in the handle slot 11 is fixed, that is, the space in which the handle 82 is inserted is fixed. When the thickness of the handle 82 is different, the handle 82 may not be in sufficient contact with the glue brush roller 32, resulting in the handle 82 being unable to be fully coated with adhesive, thereby reducing the fixing effect of the handle 82 on the carton board 8.

[0037] refer to Figure 5 and Figure 6 As shown, it is a second embodiment of the glue coating mechanism 30. On the basis of the first embodiment, a movable groove 33 with an upwardly curved arc structure or an upwardly inclined straight structure is provided on the front and rear walls of the glue chamber 31. The rotating shaft 34 on the glue brush roller 32 is movably installed in the movable groove 33. When the handle 82 is inserted into the handle slot 11, the glue brush roller 32 is squeezed to make the glue brush roller 32 move obliquely upward along the movable groove 33. At the same time, the glue brush roller 32 is affected by its own gravity and is also pressed against the handle 82, ensuring that the glue brush roller 32 is in full contact with the handle 82, so that the adhesive is applied more evenly and fully.

[0038] However, in the above-mentioned second embodiment, the glue brush roller 32 is movable, and after a long period of use, the sealing effect between the glue brush roller 32 and the mounting hole on the glue chamber 31 may not be ideal, and adhesive leakage may occur.

[0039] refer to Figure 7 and Figure 8As shown, it is a third embodiment of the glue coating mechanism 30, a cam block 35 is rotatably installed in the punching head 10, one end of the cam block 35 extends into the handle slot 11, and a glue chamber 31 is provided in the cam block 35, a glue brush roller 32 is rotatably installed on the glue chamber 31, and the glue brush roller 32 protrudes from the lower end surface of the cam block 35, so that after the handle 82 contacts with one end of the cam block 35 located in the handle slot 11, the cam block 35 rotates, thereby causing the glue brush roller 32 to contact the handle 82, and the glue brush roller 32 rotates to apply the adhesive in the glue chamber 31 to the handle 82. The state of the cam block 35 after rotation is shown in FIG. Figure 8 As shown, the glue chamber 31 is also connected to a liquid adding pipe 38 for adding adhesive into the glue chamber 31 .

[0040] like Figure 4 As shown, the rolling mechanism includes a accommodating cavity 20 opened on the punching head 10, a moving block 21 is installed in the accommodating cavity 20 to slide up and down, a rolling roller 23 is rotatably installed at the bottom of the moving block 21, and an elastic member 22 connected to the top of the accommodating cavity 20 is installed on the top of the moving block 21. The elastic member 22 is a spring. When the punching head 10 punches the carton board 8, the rolling roller 23 contacts the carton board 8, the elastic member 22 is compressed, and the rolling roller 23 is stored in the accommodating cavity 20. When the punching is completed and the punching head 10 moves horizontally, the elastic force of the elastic member 22 is released, prompting the rolling roller 23 to press the handle 82 downward tightly during the rolling process, so that the handle end 82a of the handle 82 is firmly bonded to the carton board 8

[0041] refer to Figure 4 and Fig.10 The waste collection mechanism of the device is shown, which can automatically collect the waste dropped by punching, including a movable plate 60 slidably mounted on the frame 40, and an electric roller or an electric slider is installed on the movable plate 60 to ensure its horizontal movement on the frame 40. A blanking hole 61 is arranged on the movable plate 60 at a position corresponding to the punching head 10, and a collection box 62 is detachably installed under the movable plate 60, for example, connected by bolts or snaps. When in use: when punching is required, the movable plate 60 is moved to the punching station, and the upper end surface of the movable plate 60 can support the punching of the carton board. The punching head 10 passes through the blanking hole 61 on the movable plate 60, so that the waste dropped by punching falls into the collection box 62, completing the collection of the waste, and then the movable plate 60 leaves the punching station.

[0042] like Fig.11A handle misalignment driving device for driving the two punching heads 10 to move toward each other includes a mounting frame 70, on which a forward and reverse screw 71 is rotatably mounted, and a motor 72 for driving the forward and reverse screw 71 to rotate is mounted at one end thereof, and two sliders 73 slidably connected to the mounting frame 70 are screwed on the forward and reverse screw 71, and the sliders 73 are respectively connected to the punching heads 10. When working, the motor 72 drives the forward and reverse screw 71 to rotate, so that the two sliders 73 drive the two punching heads 10 to move toward each other, and the two handle ends 82a of the handle 82 are pressed to the edges of the holes in the carton board 8.

[0043] like Figure 3 As shown, the punching head 10 is enabled to perform the lifting function by a cylinder 74 installed on the frame 4. The telescopic portion of the cylinder 74 is connected to the mounting frame 70. By driving the mounting frame 70 to lift and lower, the punching head performs the punching operation.

[0044] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
