Description

Technical Field

[0001] This invention relates to the field of bag sewing equipment technology, and more particularly to an automatic bag opening folding and sewing equipment. Background Technology

[0002] The fully automatic edge-folding and sewing equipment folds (edge-folds) and sews the edges of packaging bags through an automated process, ensuring a neat and durable seal. The angle and width of the folded edge can be adjusted to adapt to different material requirements.

[0003] However, when existing bag-sewing equipment sews packaging bags, the contents inside often cause the bag opening to remain open, making effective sewing impossible. Therefore, existing technology incorporates a clamping device to hold the bag opening in place. Furthermore, to accommodate the bag's movement during transport, this clamping device is mounted on a guide rail, following the bag's movement until it is delivered to a fully automatic hemming and sewing machine for final sewing.

[0004] However, the existing technology, which adds clamping devices and slide rails to clamp the packaging bags, results in larger equipment size, larger space occupation and less flexibility. In addition, in order to ensure that the clamping device can accurately clamp the bag opening, the machine needs to be stopped when conveying the packaging bag, which greatly reduces the efficiency of the sewing work. Utility Model Content

[0005] To overcome the shortcomings of existing equipment, such as larger size, larger space occupation, and lack of flexibility, as well as the need to stop the machine when conveying packaging bags in order to accurately clamp the bag opening, which greatly reduces the efficiency of bag sewing, this invention provides an automatic bag opening folding and sewing device.

[0008] As an improvement to the above scheme, both transmission components are provided with bends, and the two bends are in opposite directions.

[0009] As an improvement to the above solution, the positioning component includes a fixed plate, a third motor, a transmission belt, a first pull rod, a fourth motor, a rotating wheel, and a second pull rod. The fixed plate is fixedly connected to the mounting block, and the third motor is fixedly connected to the fixed plate, with the output shaft of the third motor passing through the fixed plate. The transmission belt is connected to the fixed plate, and the transmission belt wheel is fixedly connected to the output shaft of the third motor. The first pull rod is fixedly connected to the transmission belt. The fourth motor is fixedly connected to the fixed plate, and the output shaft of the fourth motor passes through the fixed plate. The rotating wheel is rotatably connected to the fixed plate, and the rotating wheel is fixedly connected to the output shaft of the fourth motor. The second pull rod is fixedly connected to the rotating wheel.

[0010] As an improvement to the above solution, the first pulling rod includes a rotating component, a vertical rod, and a pressing block; the rotating component is fixedly connected to the transmission belt; the rotating component is rotatably connected to the vertical rod via a torsion spring.

[0011] As an improvement to the above solution, the second pull rod has an elastic part in the middle and a protrusion.

[0012] As an improvement to the above solution, the first pull rod is equipped with spikes.

[0013] As an improvement to the above solution, the transmission belt is set at an angle with the left side higher than the right side when viewed from the front to the back.

[0014] As an improvement to the above solution, the connecting column is designed to be retractable.

[0015] As an improvement to the above solution, the connecting post is equipped with a lead wire bracket.

[0016] Compared with the prior art, the present invention has the following advantages: This device, through the cooperation of the first and second pulling rods, can stretch the sample material bag without requiring the sample conveyor belt to stop operating, greatly improving the sewing efficiency.

[0017] Furthermore, the positioning components of this device are smaller than those of existing mobile clamping devices, resulting in a smaller footprint. It is also more flexible and convenient than existing technologies when the device needs to be repositioned.

[0018] By using an obliquely oriented drive belt, the problem of material shifting in the material bag, which causes the opening to tilt and twist, is avoided in existing technology examples. This results in an irregular opening during subsequent sewing, significantly affecting the sewing quality of the product. Attached Figure Description

Detailed Implementation

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] An automatic bag opening folding and sewing device, such as Figure 1-7As shown, it includes a base frame 1, a connecting column 2, an electrical box 3, a sewing mechanism 4, a branch frame 5, and a first motor 7; the base frame 1 is connected to the connecting column 2; the connecting column 2 is fixedly connected to the electrical box 3; the connecting column 2 is connected to the sewing mechanism 4; the connecting column 2 is connected to the branch frame 5; the connecting column 2 is fixedly connected to the first motor 7, and the first motor 7 passes through the upper part of the connecting column 2 and is connected to the sewing mechanism 4;

[0030] It also includes a connecting frame 21, a connecting cover 22, a fitting assembly, and a positioning assembly; the connecting post 2 is fixedly connected to the connecting frame 21; the connecting frame 21 is connected to the connecting cover 22; the connecting cover 22 is connected to the fitting assembly; and the fitting assembly is connected to the positioning assembly.

[0031] The fitting assembly includes a mounting block 23, a second motor 101, a transmission component 102, and a folding frame 111; the connecting cover 22 is fixedly connected to the mounting block 23; the mounting block 23 is fixedly connected to two second motors 101 arranged in a front-to-back configuration; each of the two second motors 101 is connected to a transmission component 102, and each transmission component 102 is fixedly connected to the mounting block 23; the two transmission components 102 are jointly fixedly connected to a folding frame 111.

[0032] Both conveying components 102 are provided with bends 1021, and the two bends 1021 are in opposite bending directions. The bends 1021 make the opening of the example material bag 002 more smoothly clamped and conveyed by the two conveying components 102.

[0033] The positioning assembly includes a fixed plate 24, a third motor 201, a transmission belt 202, a first pull rod 203, a fourth motor 204, a rotating wheel 205, and a second pull rod 206. The fixed plate 24 is fixedly connected to the mounting block 23, and the third motor 201 is fixedly connected to the fixed plate 24, with the output shaft of the third motor 201 passing through the fixed plate 24. The transmission belt 202 is connected to the fixed plate 24, and the rotating wheel of the transmission belt 202 is fixedly connected to the output shaft of the third motor 201. The first pull rod 203 is fixedly connected to the transmission belt 202. The fourth motor 204 is fixedly connected to the fixed plate 24, with the output shaft of the fourth motor 204 passing through the fixed plate 24. The rotating wheel 205 is rotatably connected to the fixed plate 24, and the rotating wheel 205 is fixedly connected to the output shaft of the fourth motor 204. The second pull rod 206 is fixedly connected to the rotating wheel 205.

[0034] The first pulling rod 203 includes a rotating component 2031, a vertical rod 2032, and a pressing block 207; the rotating component 2031 is fixedly connected to the transmission belt 202; the rotating component 2031 is rotatably connected to the vertical rod 2032 via a torsion spring.

[0035] The second pull rod 206 has an elastic part 2061 in the middle and a protrusion 2062.

[0036] The first pull rod 203 is provided with spikes 2033, which makes the first pull rod 203 more firmly contact and abut against the example material bag 002.

[0037] The drive belt 202 is arranged at an angle with the left side higher than the right side when viewed from the front to the back. The angled arrangement of the drive belt 202 allows the first pull rod 203 to move obliquely upward to pull the opening of the example material bag 002.

[0038] The connecting column 2 is telescopic, which allows the device to adapt to sample material bags 002 of different heights.

[0039] The connecting post 2 is equipped with a thread guide 6, which facilitates the placement of the thread in the example thread ball 003.

[0040] Before using this device, set it to the preset working position and place the example movable clamping device 004 around the device. Then, as shown in the figure, place the example thread spool 003 on the corresponding branch frame 5 and place the sewing thread on the example thread spool 003 on the sewing mechanism 4. Set the example conveyor belt 001 to the preset position. Then, power on the device, the example conveyor belt 001 and the example movable clamping device 004, and the device will start working.

[0041] When this device starts working, a sample material bag 002 containing sufficient material is placed on the sample conveyor belt 001 manually or mechanically. The sample conveyor belt 001 then transports the sample material bag 002 towards the transport member 102. Figure 2 As shown, the gripper of the example mobile clamping device 004 starts working simultaneously to clamp the opening of the example material bag 002, and the example conveyor belt 001 pauses operation before the example mobile clamping device 004 clamps.

[0042] After the example material bag 002 is clamped, the example conveyor belt 001 starts working again, and at this time the slide rail in the example moving clamping device 004 starts working, driving the connected clamp to move synchronously with the clamped example material bag 002 until the example material bag 002 is clamped and transported by the two transmission components 102. At this time, the example moving clamping device 004 releases its clamping on the example material bag 002.

[0043] Afterwards, the two second motors 101 start working, driving their respective connected transmission components 102 to start working. At this time, the two transmission components 102 cooperate with the example conveyor belt 001 to transport the example material bag 002 to the sewing mechanism 4 until the sewing mechanism 4 finishes sewing the opening of the example material bag 002. Before the sewing mechanism 4 sews the opening, the opening of the example material bag 002 passes through the folding frame 111. When the opening of the example material bag 002 passes through the folding frame 111, it is squeezed by the folding frame 111 to produce a folded edge. In this way, the example material bag 002 can be more firmly sewn by the sewing mechanism 4.

[0044] After the sample material bag 002 is folded and sewn, it is driven by the sample conveyor belt 001 and disengaged from the sewing mechanism 4. At this time, the sewn sample material bag 002 is taken away manually or mechanically, thus completing the entire sewing work.

[0045] However, the existing technology requires the setup of the example mobile clamping device 004, which results in a large overall footprint. In actual operation, the existing technology is not flexible enough. Furthermore, in order to ensure that the example mobile clamping device 004 can accurately clamp the opening of the example material bag 002, the example conveyor belt 001 needs to be stopped, which greatly reduces the efficiency of the sewing work.

[0046] Therefore, this device is equipped with positioning components, such as... Figure 4 As shown, the first pull rod 203 is located below the second pull rod 206, and the positioning component is equipped with an electronic positioner.

[0047] When the example conveyor belt 001 is working to transport the example material bag 002 towards the transmission component 102, when the example material bag 002 moves to a preset position below the first pull rod 203 and the second pull rod 206, the electronic positioner generates a working signal. At this time, the third motor 201 starts working, driving the connected transmission belt 202 to start working. Then, the transmission belt 202 drives the connected first pull rod 203 to move towards the transmission component 102. When the first pull rod 203 moves, it will extend into the opening of the example material bag 002 and abut against one end of the opening of the example material bag 002.

[0048] Then, the fourth motor 204 starts working, driving the connected rotating wheel 205 to rotate. The rotating wheel 205 drives the connected second pulling rod 206 to rotate. When the second pulling rod 206 rotates, it extends into the opening of the example material bag 002 and abuts against the other end of the opening of the example material bag 002. At this time, the example material bag 002 is in the shape of... Figure 5 In the state shown, after the example material bag 002 is pushed against by the first pulling rod 203 and the second pulling rod 206, the opening will stretch and tighten, allowing the example material bag 002 to be conveyed into the gap between the two transmission components 102.

[0049] Furthermore, when the first pull rod 203 abuts against the opening end of the example material bag 002, the example material bag 002 is moved by the example conveyor belt 001, while the first pull rod 203 moves synchronously with the example material bag 002 under the drive of the transmission belt 202. In this way, the first pull rod 203 will not disengage from abutting against the example material bag 002.

[0050] When the second pull rod 206 abuts against the other end of the opening of the example material bag 002, the fourth motor 204 stops working. At this time, the second pull rod 206 is inserted into the example material bag 002 through the protrusion 2062, and due to the provision of the elastic part 2061, the moving example material bag 002 will stretch the second pull rod 206, so the second pull rod 206 will not disengage from the abutment against the example material bag 002.

[0051] When the opening of the sample material bag 002 is received by the two conveying components 102, the first pulling rod 203 also moves and contacts the squeezing block 207. Under the squeezing of the squeezing block 207, the vertical rod 2032 begins to rotate and disengage from the top of the opening of the sample material bag 002. At the same time, the fourth motor 204 starts to work in reverse, driving the second pulling rod 206 to rotate in the opposite direction. At this time, the second pulling rod 206 will disengage from the top of the opening of the sample material bag 002, thus facilitating the transfer of the sample material bag 002 by the two conveying components 102.

[0052] With the cooperation of the first pull rod 203 and the second pull rod 206, the sample material bag 002 can be stretched without stopping the sample conveyor belt 001, greatly improving the sewing efficiency. Furthermore, the positioning component of this device is smaller than that of the existing sample moving clamping device 004, resulting in a smaller footprint. It is also more flexible and convenient than existing technologies when repositioning is required.

[0053] This avoids the problems of existing technologies having a large overall footprint, being inflexible in actual work, and requiring the example conveyor belt 001 to be stopped in order to ensure that the example mobile clamping device 004 can accurately clamp the opening of the example material bag 002, which greatly reduces the efficiency of the sewing work.

[0054] Furthermore, the first pull rod 203 is provided with spikes 2033, so that the first pull rod 203 can more firmly contact and abut against the example material bag 002;

[0055] Furthermore, when the sample material bag 002, containing sufficient material, is conveyed by the sample conveyor belt 001, the belt inevitably vibrates, causing the material in the bag to shift. Under the pressure of this shifted material, the opening of the bag 002 tilts and twists. This results in an irregular opening during subsequent sewing, significantly affecting the sewing quality of the product.

[0056] Therefore, as Figure 3 As shown, the transmission belt 202 is arranged obliquely with the left side higher than the right side from a front-to-back perspective. When the first pull rod 203 moves against the example material bag 002, it can move obliquely upward, thus pulling the opening of the example material bag 002 upward. This makes the opening of the example material bag 002 regular and avoids the problem in the prior art where the material in the example material bag 002 shifts, causing the opening to tilt and twist, resulting in an irregular opening during subsequent sewing work, which greatly affects the sewing quality of the product.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
