Description

TECHNICAL FIELD

[0001] The utility model relates to packing equipment technical field especially relates to a portable sewing machine. BACKGROUND

[0002] The prior art portable sewing machine in the process of using, in the working condition, since being in the sewing work, need ceaseless delivery sewing thread, but in the process of delivering sewing thread, the thread roll will continue to rotate, and in the shutdown, since the thread roll will have the rotation state change to the stationary state, but under the action of inertia, make the thread roll will more rotate about a circle, further lead to sewing thread in the slack state, and then in the process of sewing, need the staff to hold the equipment and move around, in this process, sewing thread will be influenced by the airflow and swing greatly, and since sewing thread is in the slack state, make sewing thread easy to twist and lead to sewing thread knotting problem, when the sewing thread knotting, in the process of using, will run in the process, will appear the broken line and the problem such as skipping line, further influence the sewing effect. SUMMARY

[0003] In order to overcome the shortcoming mentioned in the background art, the utility model provides a portable sewing machine.

DETAILED DESCRIPTION

[0013] The preferred technical scheme of the utility model is described in detail below with reference to the drawings.

[0014] EMBODIMENT

[0015] A hand-held bag sewing machine, as shown in the figure, comprises mounting frame 1, handle 2, lifting ring 3, bag sewing machine body 4, sewing system 5, base 6, thread rack 7, thread roll 8 and first guider 9. Figures 1-4 Mounting frame 1 is provided with handle 2. Lifting ring 3 is installed on mounting frame 1. Bag sewing machine body 4 is installed on mounting frame 1. Sewing system 5 is installed on bag sewing machine body 4. Base 6 is installed on bag sewing machine body 4. Thread rack 7 is installed on bag sewing machine body 4. Thread roll 8 is installed on thread rack 7. Sewing thread 8001 is wound on thread roll 8. First guider 9 is installed on bag sewing machine body 4.

[0016] It further comprises slide rail 10, sliding block 11, second guider 12, counterweight 13 and trigger 14. Bag sewing machine body 4 is provided with slide rail 10. Sliding block 11 is connected with slide rail 10. Second guider 12 is fixedly connected with sliding block 11. Counterweight 13 is fixedly connected with second guider 12. Trigger 14 is fixedly connected with bag sewing machine body 4 and contacts with counterweight 13.

[0017] Alarm is installed on mounting frame 1 and communicates with trigger 14. Counterweight 13 and trigger 14 contact to operate the alarm, which is used to remind the staff of the problem of broken sewing thread 8001.

[0018] The second guide 12 is arranged in an inclined state to guide the sewing thread 8001 and avoid excessive twisting of the sewing thread 8001.

[0019] Firstly, the line roll 8 is installed on the frame 7, then the worker holds the portable bag sewing machine by the handle 2 and connects the portable bag sewing machine with the lifting ring 3 through the external hanging device, and then the portable bag sewing machine is hung and suspended, which is convenient for the worker to carry out subsequent bag sewing work on the packaging bag. Then the worker threads the sewing thread 8001 on the line roll 8 through the first guide 9 and the second guide 12 in sequence, and finally through the needle hole on the sewing system 5. Then the worker holds the device by the handle 2 and moves to the packaging bag to be sewn, and then controls the sewing system 5 to operate, so that the presser foot on the sewing system 5 is lifted and drives the moving of the sewing system 5 to approach the right side of the packaging bag opening. Then the presser foot is controlled to be pressed close to the base 6, and then the sewing system 5 is controlled to operate, and the worker holds the handle 2 and moves to the left side of the packaging bag opening at the same time, so as to carry out the bag sewing work on the packaging bag. In the process of bag sewing, the sewing thread 8001 is in use, that is, the sewing thread 8001 is straightened, that is, the working state of the sewing thread 8001 is changed to Figure 4 In this process, the second guide 12 is forced to move upward under the influence of the sewing thread 8001, that is, the second guide 12 drives the sliding block 11 to move upward on the sliding rail 10. After the bag sewing work is completed, the second guide 12 moves downward under the action of the counterweight 13 and gravity, and returns to the working state as shown in Figure 4The shown stop state, that is, the second guide 12 drives the slider 11 to move downward on the slide rail 10, needs to be known that, in the working state, since it is in the sewing bag working time, it needs to continuously convey the sewing thread 8001, but in the process of conveying the sewing thread 8001, the thread roll 8 will continuously rotate, and in the stop state, since the thread roll 8 will have a rotating state change to a stationary state, but under the action of inertia, the thread roll 8 will rotate more than half a turn, and then cause the sewing thread 8001 to be in a relaxed state, and then in the process of sewing the bag, the worker needs to hold the device and move around, in this process, the sewing thread 8001 will be affected by the airflow and then swing greatly, and since the sewing thread 8001 is in a relaxed state, the sewing thread 8001 is prone to twisting and then causing the sewing thread 8001 to appear a knot problem, and then causing a broken thread problem in the subsequent sewing bag process, that is, the above-mentioned working state and stop state solve the problem, that is, in the working state, the sewing thread 8001 is in a tight state, the second guide 12 is driven to move upward, and after stopping, the second guide 12 moves downward under the action of the counterweight 13 and gravity, and stretches the sewing thread 8001, and straightens the sewing thread 8001 in a relaxed state after stopping, since the sewing thread 8001 is in a straightened state, that is, in the moving process, the sewing thread 8001 will only slightly swing under the influence of the airflow, avoiding the problem that the sewing thread 8001 twists and knots due to the too large swing amplitude of the sewing thread 8001, reducing the problem of the sewing thread 8001 knotting, when sewing the bag, the worker's line of sight will be blocked by the mounting frame 1 and the sewing machine body 4, when the broken thread problem occurs, the worker cannot discover it in time, and often discovers the broken thread problem after completing the sewing, thereby affecting the work efficiency, and when the device has a broken thread problem, the second guide 12 loses the position limiting of the sewing thread 8001 in the working state, that is, the second guide 12 quickly moves downward under the action of the counterweight 13 and gravity, and resets, and in this process, the counterweight 13 moves downward to contact the trigger 14, so that the trigger 14 operates, the alarm on the mounting frame 1 operates, reminding the worker that the broken thread problem occurs, and since the power supply of the trigger 14 is connected in series with the operation power supply of the device, that is, in the stop state, even if the counterweight 13 contacts the trigger 14, the alarm on the mounting frame 1 will not operate, and in the working state, the counterweight 13 is in a separated state from the trigger 14, that is, there will be no false alarm problem.

[0020] The above has introduced the present application in detail, and the principle and implementation mode of the present application have been described by applying specific examples; the above example description is only for helping to understand the method of the present application and its core idea; at the same time, for the general technical personnel in the art, according to the idea of the present application, the specific implementation mode and application range will be changed; in view of the above, the content of the specification should not be understood as the limitation of the present application.
