Description

Technical Field

[0001] This utility model relates to the field of sealing machine technology, specifically to a handheld electric paper edge sealing machine. Background Technology

[0002] A handheld sealing machine is a portable industrial sewing device mainly used for sealing packaging materials such as plastic woven bags, burlap sacks, and paper bags. It is widely used in industries such as chemical, building materials, and food. Handheld sealing machines are widely used for sealing packaging bags. They feature strong sealing, simple operation, and easy maintenance. The relative position between the needle and hook of the handheld sealing machine significantly affects the sealing effect of the packaging bag. Therefore, when sealing different types of packaging, it is usually necessary to manually adjust the relative position between the needle and hook. In addition, to improve the sealing effect, existing sealing processes generally involve folding the bag or using multiple stitches for staggered and tight sewing. Utility Model Content

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0015] like Figure 1-2 The handheld electric paper edge sealing machine shown includes a machine head 1, a motor 2 and a hand handle 3. The machine head 1 is also equipped with a sewing table 4, and a sewing needle 11 is provided on the machine head 1 facing the sewing table 4. On both sides of the machine head 1, there are thread spool assemblies 12 for providing sewing thread and roll-up assemblies 5 for rolling up the packaging material and guiding the bag body.

[0016] As a further provision of the above scheme, the tape winding assembly 5 includes a tape winding frame 51 and a tape winding drum 52. The end of the tape winding drum 52 faces the sewing table 4. The tape winding drum 52 is provided with a half-flare-shaped opening, and the tape winding drum 52 is provided with a tape winding through groove 53 and a bag body guide groove 54. The sewing table 4 is provided with a guide slope 41. The machine head 1 is also provided with a lifting foot 14. The outlet side of the tape winding drum 52 is positioned between the guide slope 41 and the lifting foot 14.

[0017] As a further provision of the above scheme, the roll assembly 5 also includes a fixing plate 56 and a roll suspension 57. The fixing plate 56 is used to fix the roll assembly 5 to the sewing table 4, and the roll suspension 57 is also provided with a roller 58 for guiding the roll material from the roll frame 51 into the large opening side of the roll through groove 53 of the roll drum 52.

[0018] As a further provision of the above scheme, a cutter assembly 6 is provided on the other side of the sewing table 4 opposite to the roll assembly 5. The cutter assembly 6 includes a fixed blade 61, a movable blade 62 that swings relative to the fixed blade 61, and a rocker arm 63 for driving the movable blade 62 to swing.

[0019] As a further feature of the above solution, the rocker arm 63 is screwed onto the movable blade 62, the movable blade 62 is hinged and swings relative to the fixed blade 61, and the end of the rocker arm 63 is also provided with a tension spring 64, which is used to drive the rocker arm 63 to reset.

[0020] refer to Figure 1 The portable electric paper edge sealing machine of this embodiment includes a machine head 1, a motor 2, and a handle 3. The handle 3 controls the motor 2 to start and stop. The output shaft of the motor 2 extends into the machine head 1 and drives the sewing needle 11 on the sewing table 4 on the machine head 1 to sew the bag body on the sewing table 4. Furthermore, unlike conventional sealing machines that directly sew the bag body, the sealing machine of this embodiment also has a thread spool assembly 12 for providing sewing thread and a roll assembly 5 for rolling up the packaging material and guiding the bag body on both sides of the machine head 1. The roll assembly 5 can improve the sealing effect and sealing strength of the bag and solve the possibility of material leakage from the seam gaps.

[0021] As described above, the roll assembly 5 in this embodiment includes a roll frame 51 and a roll drum 52. The end of the roll drum 52 faces the sewing table 4. The roll drum 52 has a half-flare-shaped opening and is provided with a roll through groove 53 and a bag guide groove 54. In use, the operator needs to insert the roll on the roll frame 51 into the rear opening of the roll through groove 53 and extend it from the front end. Guided by the shape of the roll drum 52, it changes from a single piece to a double-folded package. The operator then folds the target bag and feeds it into the bag guide groove 54. After passing through the roll drum 52, the roll on the sewing table 4 covers and fastens the top and bottom of the bag, sealing the opening of the bag. At this time, the presser foot 14 on the machine head 1 presses and shapes both parts, and the sewing needle 11 sews them closed.

[0022] As a further provision of the above scheme, the roll assembly 5 also includes a fixing plate 56 and a roll suspension 57. The fixing plate 56 is used to fix the roll assembly 5 to the sewing table 4. The roll suspension 57 is also provided with a roller 58 for guiding the roll material from the roll frame 51 into the large opening side of the roll groove 53 of the roll drum 52. The roll suspension 57 and the roller 58 are both provided to allow the roll material to enter the roll groove 53 of the roll drum 52 better.

[0023] As a further provision of the above scheme, a cutter assembly 6 is also provided on the other side of the sewing table 4 opposite to the roll assembly 5. The cutter assembly 6 includes a fixed blade 61, a movable blade 62 that swings relative to the fixed blade 61, and a rocker arm 63 for driving the movable blade 62 to swing. The rocker arm 63 is screwed onto the movable blade 62. The movable blade 62 is hinged and swings relative to the fixed blade 61. A tension spring 64 is also provided at the end of the rocker arm 63. The tension spring 64 is used to drive the rocker arm 63 to reset.

[0024] As described above, in this embodiment of the cutter assembly 6, after the sealing is completed, the worker can pull the rocker arm 63 to drive the moving blade 62 to form a shearing force with the fixed blade 61, and manually cut the sealed material. The tension spring 64 is used to reset the moving blade 62 to the open state with the fixed blade 61 after the cutting is completed.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
