[0002] Woven bag edge sealing devices are devices used to seal the edges of woven bags. Woven bag edge sealing devices are usually used to process the edges of woven bags to prevent them from loosening or unraveling. It can reinforce the edges of woven bags to make them more durable and help prevent the contents of the bag from leaking out or being damaged. Edge sealing devices usually reinforce the edges of woven bags by heat sealing, heating the edges of the woven bag and then sealing them together by pressure to form a strong sealed edge.

This edge sealing method also requires the staff to constantly adjust the position of the woven bag to seal the edges on both sides of the woven bag, making the processing efficiency less than ideal. Therefore, it is necessary to design a woven bag edge sealing device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] See also Figure 1-4 The utility model provides a woven bag edge sealing device, including a base frame 1, a strip seat 2 is fixedly connected to one side of the top of the base frame 1, and a heat sealing plate 3 is provided above the base frame 1, which is located directly above the strip seat 2 and can be lifted and lowered and is used to heat seal the side of the woven bag. A mounting rod 4 is rotatably connected to the top of the base frame 1 along its length direction, and two vertical fixing plates 5 are fixedly connected to the circumferential surface of the mounting rod 4. The top of the base frame 1 also has an opening, and one side of the two fixing plates 5 is provided with a clamping plate 6 for fixing the side of the woven bag, and a rotating mechanism for driving the mounting rod 4 to rotate 90 degrees is provided on the base frame 1. When the device is used to seal the edge of the woven bag, the woven bag can be sealed. The bag is placed in an L-shaped state on two fixing plates 5, and its two sides can be fixed to the side edges of the fixing plates 5 by two clamping plates 6 respectively. The side edges of the woven bag need to extend a certain distance outside the fixing plates 5 to reserve a position for edge sealing. At this time, one side of the woven bag will be located on the strip seat 2, and the heat sealing plate 3 can be lowered and heat-sealed. After that, the mounting rod 4 can be rotated 90° under the action of the rotating mechanism, so that the other side of the woven bag will also follow the rotation and move to the strip seat 2, so that the heat sealing plate 3 can seal the other side of the woven bag again. The staff does not need to manually adjust the position of the woven bag when sealing the edges, thereby realizing efficient edge sealing operations on both sides of the woven bag.

[0021] The specific connection method between the mounting rod 4 and the base frame 1 is as follows: two left-right symmetrical fixed blocks 7 are fixedly connected to the top of the base frame 1, a rotating rod 8 is rotatably connected between the two fixed blocks 7 via a bearing, and the mounting rod 4 is fixedly sleeved on the rotating rod 8, so that the mounting rod 4 can form a rotatable connection at the top of the base frame 1.

[0022] In order to enable the mounting rod 4 to rotate, in some embodiments, it is proposed that the rotating mechanism includes a servo motor 9 fixedly mounted on one side of the base frame 1 with the output shaft facing upward, the end of the output shaft of the servo motor 9 is fixedly connected to an active bevel gear 10, one side of the rotating rod 8 passes through one of the fixed blocks 7 and is fixedly connected to a driven bevel gear 11 meshing with the active bevel gear 10, when the output shaft of the servo motor 9 rotates, the active bevel gear 10 can be driven to rotate, and the active bevel gear 10 can drive the driven bevel gear 11 to rotate accordingly through tooth matching, and realize the rotation of the mounting rod 4, so that the mounting rod 4 can drive the two fixed plates 5 to flip 90° along their axial direction.

[0023] The specific way in which the splint 6 can fix the side of the woven bag is as follows: two symmetrical guide rods 12 are inserted and connected on the side of the two fixed plates 5 away from the mounting rod 4, the splint 6 is fixedly connected to one side of the two guide rods 12, and the two guide rods 12 are fixedly connected to a connecting plate 13 on the side away from the splint 6. The surface of the fixed plate 5 is rotatably connected to a threaded rod 14 through a bearing, the threaded rod 14 is inserted on the connecting plate 13 through threaded cooperation, and one end of the threaded rod 14 is fixedly connected to a knob 15. The staff can rotate the knob 15 by hand so that the threaded rod 14 can drive the connecting plate 13 to move forward and backward through the threaded cooperation, which also allows the splint 6 to approach or move away from the surface of the fixed plate 5, so that the splint 6 can press or loosen the side of the woven bag.

[0024] It should be noted that there are notches on the surfaces of the two knobs 15, so that when the woven bag is placed on the two fixing plates 5, its excess part can pass through the notches, which makes the device compatible with woven bags of different sizes for edge sealing and has high applicability.

[0025] Furthermore, a mounting frame is fixedly connected to one side of the base frame 1, on which a servo electric cylinder with a piston rod facing downward is fixedly mounted, and the end of the piston rod of the servo electric cylinder is fixed to the top of the heat sealing plate 3. When the piston rod of the servo electric cylinder is extended or retracted, the heat sealing plate 3 can be driven to rise and fall, so that the heat sealing plate 3 can press the side of the woven bag down on the strip seat 2 and perform heat sealing.

[0026] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0027] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0028] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
