Description

Technical Field

[0001] The utility model relates to the field of sealing devices, in particular to a packaging carton closing and sealing device. Background Art

[0002] Packaging cartons are made of paper products and are used to pack various items. Cartons are low-cost, easy to pack, suitable for adding fillers, clean, etc., suitable for product factory packaging, item transportation, material sorting, etc. Sealing devices are required in packaging;

[0003] For example, the Chinese utility model (publication number CN220701551U) discloses a packaging carton closing and sealing device, including a shell, a shell cover, a handle, a fixed shell and other structures. This technical solution can limit the position of the tape, and the end of the tape can be transmitted through the slot and the strip groove position. The cooperation of the fixed shell, the pull rod, the pressure plate, the spring and the anti-sticking plate can squeeze and limit the position of the tape. At the same time, the setting of the anti-sticking plate will not affect the viscosity of the tape.

[0004] However, the above technical solution still has the following technical problems in actual use: when in use, one hand is required to hold the handle, and the other hand is required to press the pressure rod when the tape needs to be cut. In actual use, the operator needs to use the other hand to stabilize the packaging box, which makes it inconvenient for the operator to operate and reduces the sealing quality. The above technical solution requires the operator to operate with two hands, which is complicated to operate, reduces the sealing efficiency, and is very inconvenient to operate.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0020] like Figures 1 to 3 The packaging carton closing and sealing device shown in the figure comprises a shell 1, a sealing cover 15 is threadedly connected to the rear side of the shell 1, a positioning frame 4 is connected to the shell 1, the positioning frame 4 is connected to the fixing frame 5, the fixing frame 5 is slidably connected to the sliding rod 6, the bottom of the sliding rod 6 is connected to a fixing plate 22, the fixing plate 22 is connected to a cutting blade 11, the sliding rod 6 is sleeved with a reset spring 21, the free end of the reset spring 21 is connected to the fixing frame 5, the fixing frame 5 is provided with a through hole 18, the cutting blade 11 can pass through the through hole 18, the shell 1 is connected to a gripping handle 9, the outer side wall of the shell 1 is rotatably connected to a rotating rod 3, the rotating rod 3 is connected to a first connecting rod 7 and a second connecting rod 8, the right end of the first connecting rod 7 is in contact with the top of the sliding rod 6, the gripping handle 9 is provided with a sliding groove 10, the left end of the second connecting rod 8 passes through the sliding groove 10 and is slidably connected to the sliding groove 10, the inner side wall at the bottom of the sliding groove 10 is connected to a control spring 13, and the free end of the control spring 13 is connected to the second connecting rod 8.

[0021] The shell 1 is provided with a first outlet 16, and the positioning frame 4 is provided with a second outlet 17. The positioning frame 4 is threadedly connected with a threaded rod 20, and the threaded rod 20 is rotatably connected with a resistance plate 19, which resists against the inner wall of the positioning frame 4, and the resistance plate 19 is rotationally limited by the inner wall of the positioning frame 4. The inner wall of the positioning frame 4 is connected with an anti-sticking plate, and the inner side of the shell 1 is connected with a mounting column 14. The second connecting rod 8 is connected with a resistance rod 12, and the resistance rod 12 resists against the inner wall of the bottom of the sliding groove 10 to avoid the second connecting rod 8 being too pressed down under the action of the control spring 13, thereby avoiding the first connecting rod 7 being located at a position far from the upper end of the top of the sliding rod 6. The lower side of the shell 1 is rotatably connected with a flattening roller 2.

[0022] The specific implementation process is as follows:

[0023] When installing, unscrew the sealing cover 15, buckle the hollow part of the tape roll on the positioning column, then pull out the tape along the rubber head, pass the tape through the first outlet 16 and the second outlet 17 in sequence, and then pull it out from the right side. When not in use, the threaded rod 20 can be twisted to drive the contact plate 19 to press down and fix the rubber head. When in use, the contact plate 19 can no longer press the tape; when in use, hold the holding handle with your hand, with the thumb located on the left side of the holding handle and below the second connecting rod 8, and the other four fingers hold the right side of the holding handle 9. When sealing, the contact plate 19 does not contact the tape, and the right end of the rubber head is attached to the opening, and then the outer shell 1 is pulled out to complete the sealing. After the sealing is completed, the cutting blade 11 is moved down to cut the tape; when the tape needs to be cut, the thumb pushes the second connecting rod 8 upward, so that the second connecting rod 8 rotates clockwise with the rotating rod 3 as the axis. Rotate, so that the rotating rod 3 also rotates clockwise, and at the same time the control spring 13 is pulled, and the clockwise rotation of the rotating rod 3 can drive the first connecting rod 7 to rotate clockwise, so that the right end of the first connecting rod 7 moves downward, and then the sliding rod 6 is pressed to move downward. The sliding rod 6 moves downward and drives the fixed plate 22 and the cutting blade 11 to move downward, and at the same time the reset spring 21 is pulled, so that the cutting blade 11 can slide out of the hole 18 to complete the cutting of the rubber strip. After the cutting is completed, the thumb releases the second connecting rod 8, and under the action of the control spring 13 and the restoring force of the restoring spring, the cutting blade 11 automatically moves up and is retracted into the fixed frame 5, and the tape can be continued to be used for sealing. After one tape sealing is completed, the sub-flat roller can be placed at the tape posting location, and then the moving shell 1 can further compact the posted tape through the rolling sub-flat roller to improve the sealing effect.

[0024] The technical solution cooperates with the first connecting rod 7, the second connecting rod 8 and the rotating rod 3 so that the operator can press the sliding rod 6 with the hand holding the handle 9, thereby completing the cutting of the tape, so that the operator only needs one hand to complete the sealing, and the other hand can simultaneously support and fix the packaging carton, etc., which is convenient for the staff to operate and greatly improves the sealing efficiency and quality. The cutting can be completed by pushing the second connecting rod 8 with the thumb, which is simple to operate and easy to use; the threaded rod 20 and the contact plate 19 can fix the tape to avoid the problem of being unable to find the tape head later; the reset spring 21 can also automatically retract the cutting blade 11 into the fixed frame 5 to avoid accidental injury to the staff; the contact rod 12 prevents the first connecting rod 7 from easily pressing the sliding rod 6; the flattening roller 2 can flatten and compress the tape again after the tape is sealed, thereby improving the applicability of the device and the tape sealing effect.

[0025] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
