Description

Technical Field

[0001] The utility model relates to the technical field of carton sealing devices, in particular to a sealing tape identification device. Background Art

[0002] Sewing thread is the thread required for knitted clothing products. Sewing thread can be divided into three categories according to raw materials: natural fiber, synthetic fiber sewing thread, and mixed sewing thread. In the production process of sewing thread, it is necessary to wind the finished sewing thread, and then pack the wound sewing thread into boxes. When packing the existing sewing thread, manual packing is mostly used, and the sewing thread needs to be arranged in the packing box. When multiple layers are required, the efficiency of manually arranging the sewing thread is very slow, which is not conducive to the production efficiency of the entire production line.

[0003] During the production of sewing thread, a heat shrink packaging machine is used to wrap the outer layer of the sewing thread, so as to avoid the phenomenon of the sewing thread falling apart. Then the wound sewing thread is placed in a box by a manipulator, and then the box is sealed by a carton sealer. The manipulator will directly place the box to be sealed on the conveyor belt, and the conveyor belt will vertically send it into the carton sealer for sealing. Generally, the boxes used to hold the sewing thread are cardboard boxes. Although the traditional carton sealer can automatically fold the box cover and paste it with tape, the dust, impurities, etc. on the surface of the area to be pasted on the cardboard box are not effectively cleaned, resulting in the problem that the tape is not firmly pasted after pasting. Moreover, since the boxes for holding the sewing thread are small in volume and light in weight, they are prone to relative movement with the conveying mechanism during the conveying process, so it is not convenient for actual use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a sealing tape identification device, which solves the problems in the prior art that the dust, impurities, etc. on the surface of the area to be pasted on the cardboard box are not effectively cleaned, resulting in the problem that the tape is not firmly pasted after pasting, and since the boxes for holding the sewing thread are small in volume and light in weight, they are prone to relative movement with the conveying mechanism during the conveying process, so it is not convenient for actual use.

[0027] Refer to Figures 1-5, The carton sealing tape recognition device includes a workbench 1. A carton sealer 3 is arranged on the surface of the workbench 1. A conveyor 2 is installed on the side wall of the workbench 1. A conveyor belt is arranged on the surface of the workbench 1. A connecting frame 4 is fixedly installed on the surface of the workbench 1. A first sensor 14 and a second sensor 15 are fixedly installed on the surface of the connecting frame 4. An auxiliary mechanism for closing and cleaning the carton is arranged on the surface of the connecting frame 4. A limiting mechanism for limiting the carton is arranged on the surface of the connecting frame 4. The conveyor belt includes a conveyor belt 6, two rollers 5 and a first motor 7. A long hole 23 is opened on the surface of the workbench 1. The two rollers 5 are respectively rotatably connected to both ends of the long hole 23. The first motor 7 is fixedly installed on the side wall of the workbench 1. The output shaft port of the first motor 7 is fixedly connected to the roller 5. The conveyor belt 6 is sleeved on the surfaces of the two rollers 5. Convexities 24 are arranged at equal intervals on the surface of the conveyor belt 6. During use, the carton filled with sewing thread is placed on the conveyor belt. The limiting mechanism is adjusted so that the carton can be located at the center of the conveyor belt under the action of the limiting mechanism. Then it is conveyed by the conveyor belt. When the conveyor belt moves the carton to the bottom position of the connecting frame 4, the second sensor 15 senses the carton, transmits the signal to the external controller, and controls the auxiliary mechanism through the controller. The auxiliary mechanism is used to fold and clean the lid on the top of the carton. Then the conveyor belt continues to carry the carton into the interior of the carton sealer 3. The carton sealer 3 uses tape to paste the cleaned box lid. When the conveyor belt 6 in the conveyor belt moves the carton, the carton will contact the convexities 24. Therefore, under the push of the convexities 24, the carton is driven to move synchronously, so that there is no relative movement between the carton and the conveyor belt 6. The operation of the conveyor belt 6 depends on the controller to control the first motor 7. The first motor 7 drives the roller 5 to rotate, and the roller 5 drives the conveyor belt 6 to move, thus realizing the normal operation of the device.

[0028] Further, the auxiliary mechanism includes two vertical rods 12. A connecting rod 17 is rotatably penetrated through the surfaces of the two vertical rods 12. A rolling brush 16 is fixedly installed on the surface of the connecting rod 17 at a position between the two vertical rods 12. A driving mechanism for driving the connecting rod 17 and the rolling brush 16 to rotate is arranged on the surface of the connecting frame 4. During use of the auxiliary mechanism, the driving mechanism is used to drive the connecting rod 17 to rotate, and the connecting rod 17 drives the rolling brush 16 to rotate. The vertical rod 12 and the connecting frame 4 are slidably connected. Therefore, the sliding of the vertical rod 12 can be used to control the rolling brush 16 to be located on the top of the carton, so as to clean the box lid by using the rolling brush 16, which is convenient for tape bonding.

[0029] Further, the auxiliary mechanism further includes two third electric telescopic rods 13. The connecting frame 4 is arranged in an "n" shape. Vertical grooves are formed in both arms of the connecting frame 4. Slide plates 22 are slidably connected to the interiors of the two vertical grooves respectively. The two third electric telescopic rods 13 are fixedly installed on the surface of the connecting frame 4, and the output ends of the two third electric telescopic rods 13 are fixedly connected to the two slide plates 22 respectively. Fourth electric telescopic rods 18 are fixedly installed on one sides of the two slide plates 22 away from each other. The output end of the fourth electric telescopic rod 18 is fixedly installed with a push rod 8. The push rod 8 slidably penetrates through the slide plate 22. The connecting rod 17 movably penetrates through the push rod 8. By arranging the third electric telescopic rod 13, the third electric telescopic rod 13 drives the two slide plates 22 to move in the vertical direction, thereby driving the fourth electric telescopic rods 18, the push rods 8 and the connecting rod 17 to move synchronously. When the slide plate 22 moves to a position just flush with the top of the box body, it stops. At this time, the fourth electric telescopic rod 18 is started, and the fourth electric telescopic rod 18 drives the push rod 8 to move, so as to fold the two box lids on the top of the box body by using the two push rods 8. At this time, the rolling brush 16 is just on the top of the box lid of the folding shaft, so the box lid can be cleaned at the same time. The push rod 8 is set to have a longer length, so when the box body is conveyed into the sealing machine 3 on the conveyor belt 6, it will also be in a closed state, which is convenient for the sealing operation.

[0030] Further, the driving mechanism includes a second motor 19. The second motor 19 is fixedly installed on the side wall of the push rod 8. The output shaft end of the second motor 19 is fixedly installed with a driving gear 20. A driven gear 21 is rotatably sleeved on the side wall of the push rod 8 relative to the position of the connecting rod 17. The connecting rod 17 slidably penetrates through the center of the driven gear 21. The driving gear 20 meshes with the driven gear 21. In the use of the driving mechanism, the second motor 19 is started, the second motor 19 drives the driving gear 20 to rotate, the driving gear 20 drives the driven gear 21 to rotate, and the driven gear 21 drives the connecting rod 17 to rotate, so as to achieve the purpose of rotating the rolling brush 16.

[0031] Further, the limiting mechanism includes two limiting rods 25. The two limiting rods 25 are both slidably connected to the surface of the workbench 1. Two first electric telescopic rods 9 are fixedly installed on the surface of the connecting frame 4. The output ends of the two first electric telescopic rods 9 are fixedly connected to the two limiting rods 25 respectively. In the use of the limiting mechanism, the first electric telescopic rods 9 are started, and the two first electric telescopic rods 9 drive the two limiting rods 25 to move, so that the distance between the two limiting rods 25 is just the same as the size of the box body. Then the worker only needs to place the box body between the two limiting rods 25. Although the mass of the box body is light and there will be friction when it contacts the limiting rods 25, the box body will also overcome this friction under the action of the convex 24 on the conveyor belt 6, which is convenient for operation and use.

[0032] Further, connecting plates 11 are fixedly installed on the surfaces of both limiting rods 25. The positions of the two connecting plates 11 correspond to the conveyor 2. A second electric telescopic rod 10 is fixedly installed on the surface of the connecting plate 11 away from the conveyor 2. A push plate 26 is fixedly installed at the output end port of the second electric telescopic rod 10. In order to facilitate differential sales, the factory uses plastic boxes other than paper boxes for packaging. The plastic boxes are generally of the same volume and shape as the paper boxes, so it is convenient for the manipulator to place the sewing thread in the box. However, the packaged boxes are all conveyed on the conveyor belt 6, and the plastic boxes do not need to be folded and sealed. Therefore, a first sensor 14 is provided. When the first sensor 14 senses a plastic box, it will transmit a signal to the controller. The controller controls the first motor 7 to stop and will cause the second electric telescopic rod 10 to drive the push plate 26 to move. The second electric telescopic rod 10 and the push plate 26 are used to push the plastic box from the side. An inclined groove is formed on the surface of one of the two limiting rods 25 close to the conveyor 2. Therefore, when the push plate 26 pushes the plastic box, the plastic box can directly pass through the inclined groove and move onto the connecting plate 11, and then move from the connecting plate 11 onto the conveyor 2. The conveyor 2 is used to convey the plastic box. When the first sensor 14 senses a paper box, the second electric telescopic rod 10 remains stationary, and all actions are still carried out in the manner described above.

[0033] A carton sealing production line includes the above-mentioned carton tape identification device.

[0034] In summary, during use, place the cardboard box filled with sewing thread on the conveyor belt, adjust the limit mechanism so that the cardboard box can be located at the center position of the conveyor belt under the action of the limit mechanism, and then use the conveyor belt for transportation. When the conveyor belt moves the cardboard box to the bottom position of the connecting frame 4, the second sensor 15 senses the cardboard box, transmits the signal to the external controller, and controls the auxiliary mechanism through the controller. Use the auxiliary mechanism to fold and clean the lid on the top of the cardboard box. Then the conveyor belt continues to carry the cardboard box into the inside of the sealing machine 3, and use the sealing machine 3 to paste the cleaned box lid with tape. When the conveyor belt 6 in the conveyor belt moves the cardboard box, the cardboard box will contact the protrusion 24. Therefore, under the push of the protrusion 24, the cardboard box is driven to move synchronously, so that there is no relative movement between the cardboard box and the conveyor belt 6. The operation of the conveyor belt 6 depends on the controller to control the first motor 7. The first motor 7 drives the roller 5 to rotate, and the roller 5 drives the conveyor belt 6 to move, thus realizing the normal operation of the device. During the use of the auxiliary mechanism, use the driving mechanism to drive the connecting rod 17 to rotate, and the connecting rod 17 drives the brush 16 to rotate. The vertical rod 12 and the connecting frame 4 are slidably connected. Therefore, the vertical rod 12 can be used to slide to control the brush 16 to be located on the top of the cardboard box, so as to use the brush 16 to clean the box lid, which is convenient for tape bonding. By setting the third electric telescopic rod 13, the third electric telescopic rod 13 drives the two slide plates 22 to move in the vertical direction, so as to drive the fourth electric telescopic rod 18, the push rod 8 and the connecting rod 17 to move synchronously. When the slide plate 22 moves to just be flush with the top of the box body, stop. At this time, start the fourth electric telescopic rod 18, and the fourth electric telescopic rod 18 drives the push rod 8 to move, so as to use the two push rods 8 to fold the two box lids on the top of the box body. At this time, the brush 16 is just on the top of the box lid of the folding shaft, so the box lid can be cleaned at the same time. The push rod 8 is set to be relatively long. Therefore, when the box body is transported into the inside of the sealing machine 3 on the conveyor belt 6, it will also be in a closed state, which is convenient for the sealing operation. During the use of the driving mechanism, start the second motor 19, the second motor 19 drives the driving gear 20 to rotate, the driving gear 20 drives the driven gear 21 to rotate, and the driven gear 21 drives the connecting rod 17 to rotate, so as to realize the purpose of rotating the brush 16. During the use of the limit mechanism, start the first electric telescopic rod 9, and the two first electric telescopic rods 9 drive the two limiting rods 25 to move, so that the distance between the two limiting rods 25 is just the same as the size of the box body. Then the worker only needs to place the box body between the two limiting rods 25. Although the quality of the box body is light and there will be friction when contacting the limiting rod 25, the box body will also overcome this friction under the action of the protrusion 24 on the conveyor belt 6, which is convenient for operation. In order to facilitate differential sales, the factory will use plastic boxes other than cardboard boxes for packaging. This plastic box is generally of the same volume and shape as the cardboard box, so it is convenient for the manipulator to place the sewing thread in the box body. However, the packaged box bodies will all be transported on the conveyor belt 6.The plastic box does not need to be folded and sealed, so a first sensor 14 is provided. When the first sensor 14 senses the plastic box, it will transmit a signal to the controller. The controller controls the first motor 7 to stop and makes the second electric telescopic rod 10 drive the push plate 26 to move. The second electric telescopic rod 10 and the push plate 26 are used to push the plastic box from the side. One of the two limiting rods 25 near the conveyor 2 has an inclined groove on its surface. Therefore, when the push plate 26 pushes the plastic box, the plastic box can directly pass through the inclined groove and move onto the connecting plate 11, and then move from the connecting plate 11 onto the conveyor 2. The conveyor 2 is used to convey the plastic box. When the first sensor 14 senses a paper box, the second electric telescopic rod 10 remains stationary. Through this automatic recognition method, the diversion between the paper box and the plastic box can be achieved, facilitating the assembly line production.
