Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bags, in particular to a high-strength plastic woven bag. Background Art

[0002] Patent application number 202221864093.9 discloses a high-strength plastic woven bag, including a bag body, an inner film, a connecting piece and a fixing strip, etc. The bag body can be easily lifted by pulling the draw rope, and the connecting piece and the bag body can be rolled on the fixing strip by opening the first pressure plate and the second pressure plate and rotating the fixing strip. The first pressure plate and the second pressure plate are rotated to clamp the fixing strip together with the bag body, and the screw is rotated to make the screw enter the rectangular groove, push the gasket so that the groove on the gasket is stuck on the positioning pin, and turn the nut so that the nut conflicts with the gasket, thereby sealing the bag body.

[0003] Although the above disclosed clamping scheme for the bag body can achieve a sealing effect, the process of using it according to the above steps is too complicated and inconvenient to operate. In addition, using a drawstring to pull the bag body will cause the connection area between the bag body and the two ends of the drawstring to be subjected to excessive force, which may easily cause the bag body to tear in this area. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a high-strength plastic woven bag. After rotating the movable plate, the nut is screwed on to complete the sealing of the bag opening. Compared with the existing complicated sealing process, the operation method is simpler and convenient to seal the bag. When the pull rope is used through the reinforcement belt, not only the force-bearing area of ​​the bag is increased, but also the bag can be lifted up, the force applied to the bag is reduced, and the bag is further prevented from being torn.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-strength plastic woven bag comprises a bag body, a PE film is provided on the inner side of the bag body, a drawstring is provided on the outer side of the bag body, both ends of the drawstring are fixedly connected with reinforcement belts, the reinforcement belt is annular and is sleeved on the outer side of the bag body, the reinforcement belt is sewn to the bag body, a fixing plate is fixedly connected to the outer side of the upper opening of the bag body, a pressing groove is provided on the side of the fixing plate adjacent to the bag body, a movable plate is connected to the right side of the fixing plate through a hinge, a sliding groove is provided on the side of the movable plate adjacent to the bag body, a spring is fixedly connected in the sliding groove, a pressure strip matched with the pressure groove is fixedly connected to the end of the spring, the pressure strip is slidably connected to the sliding groove, the sides of the movable plate and the fixed plate are fixedly connected with half bolts, and the outer sides of the two half bolts are threadedly connected with the same nut.

[0007] Furthermore, a magnetic block is fixedly embedded on the side of the fixing plate away from the bag body.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. The movable plate is rotated to open and close through the hinge, so that the pressure strip can press the opening of the bag body into the pressure groove, and cooperate with the spring to press and seal it. The position of the movable plate is fixed by two half bolts and nuts, so that the opening of the bag body maintains a sealing effect. After rotating the movable plate, screwing on the nut, the bag opening can be sealed. Compared with the existing complicated sealing process, the operation method is simpler and convenient for sealing the bag body.

[0010] 2. When the drawstring is used through the reinforcement belt, not only the force-bearing area of ​​the bag is increased, the force is dispersed and it is not easy to tear, but also the reinforcement belt is annular. When the bag is lifted, the reinforcement belt on the lower side can lift the bag upward, thereby reducing the force on the bag and further avoiding the bag from being torn.

[0011] 3. The magnet can be used to adsorb the nut when it is not in use, so as to keep the nut in place and avoid the nut being lost due to random placement. BRIEF DESCRIPTION OF THE DRAWINGS

Example

[0019] See attached Figure 1-4 As shown, a high-strength plastic woven bag comprises a bag body 1, a PE film is provided on the inner side of the bag body 1, a drawstring 2 is provided on the outer side of the bag body 1, both ends of the drawstring 2 are fixedly connected with a reinforcing belt 3, the reinforcing belt 3 is annular and is sleeved on the outer side of the bag body 1, the reinforcing belt 3 is sewn and connected to the bag body 1, a fixing plate 4 is fixedly connected to the outer side of the upper opening of the bag body 1, a pressing groove 5 is provided on the side of the fixing plate 4 adjacent to the bag body 1, a movable plate 7 is connected to the right side of the fixing plate 4 through a hinge 6, a sliding groove 8 is provided on the side of the movable plate 7 adjacent to the bag body 1, a spring 9 is fixedly connected in the sliding groove 8, a pressure strip 10 adapted to the pressure groove 5 is fixedly connected to the end of the spring 9, the pressure strip 10 is slidably connected to the sliding groove 8, half bolts 11 are fixedly connected to the sides of the movable plate 7 and the fixed plate 4, the outer sides of the two half bolts 11 are threadedly connected with the same nut 12, and a magnetic block 13 is fixedly embedded on the side of the fixing plate 4 away from the bag body 1.

[0020] Working principle: In the utility model, when the bag body 1 is sealed, the movable plate 7 is rotated first. The specific process is that the movable plate 7 rotates toward the fixed plate 4 with the rotating shaft of the hinge 6 as the axis. The movable plate 7 drives the pressure strip 10 to move synchronously during rotation. The pressure strip 10 pushes the opening area of ​​the bag body 1 to move toward the pressure groove 5 of the fixed plate 4, and then the bag body 1 is pushed into the pressure groove 5 by the pressure strip 10. After the pressure strip 10 enters the pressure groove 5, the pressure strip 10 abuts against the bag body 1. As the rotation continues, the spring 9 is squeezed by both the pressure strip 10 and the movable plate 7, so that the pressure strip 10 presses the bag body 1 tightly. , until the movable plate 7 is fitted with the fixed plate 4, at which time the two half bolts 11 are combined to become a complete bolt. After the rotation of the movable plate 7 is completed, the movable plate 7 is fixed again. The specific process is to take the nut 12 off the magnetic block 13 and screw it onto the two combined half bolts 11 to complete the sealing work of the bag body 1. When lifting the bag body 1, pull the drawstring 2. The traction force of the drawstring 2 on the bag body 1 is dispersed by the force transmitted by the reinforcement belt 3. Moreover, when the reinforcement belt 3 lifts the bag body 1, the reinforcement belt 3 located at the lower side of the bag body 1 will tend to lift the bag body 1 upward.
