Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a fully automatic encapsulation device for mesh woven bags that integrates anti-sticking, bag opening, bag filling, and sealing. Background Art

[0002] The usage rate of mesh woven bags in China shows an increasing trend year by year and is now widely used in the collection and subsequent packaging of vegetables and fruits. In the later stage of harvesting crops from the farmland, it is necessary to separate the mesh woven bags into individual ones, open the bags, and seal the bags after filling to meet the subsequent transportation requirements. In China, the use of mesh woven bags is entirely achieved by manual labor, with low efficiency and high costs. Currently, due to the soft material of mesh woven bags, they are prone to adhesion and difficult to separate, so there is no fully automatic encapsulation device for mesh woven bags on the market, and this operation is all completed manually.

[0003] This application can achieve the bagging and sealing of crops in mesh woven bags, filling the technical gap in the difficult automatic encapsulation of domestic mesh woven bags. It reduces the labor cost and improves the work efficiency, having broad application prospects. Summary of the Invention

[0004] In order to solve the above problems, the present invention proposes a fully automatic encapsulation device for mesh woven bags that integrates anti-sticking, bag opening, bag filling, and sealing. It reduces the labor intensity, improves the work efficiency, and fills the technical gap in the difficult automatic encapsulation of domestic mesh woven bags.

[0005] The solution adopted by the present invention is: a fully automatic encapsulation device for mesh woven bags includes a frame, a transmission mechanism, a bag opening and sealing mechanism, a pressure sensor, a workbench, a bag dialing mechanism, and a slide. This device is a symmetric structure, with a fully automatic encapsulation device for mesh woven bags on each side. Their working methods and principles are exactly the same, and only one side will be introduced in detail in this specification.

[0006] The transmission mechanism adopts a combined structure of a self-made conveyor belt and a detachable row type positioning cap. The self-made conveyor belt is 1000 mm long, the diameter of a single positioning cap is 10 mm, the height is 10 mm, and the interval distribution is 10 mm. During operation, an operator hangs the bag ropes of 50 mesh woven bags on the detachable row type positioning caps in sequence, and adheres the detachable row type positioning caps to the self-made conveyor belt through Velcro. The interval between each positioning cap of the detachable row type positioning cap is 10 mm, effectively solving the problem of adhesion of mesh woven bags. The transmission mechanism adopts a detachable row type positioning cap structure, improving the work efficiency and having high practicality.

[0007] The bag-opening and sealing mechanism is characterized by comprising two two-finger manipulators and one clamping manipulator. The two-finger manipulators and the clamping manipulator are coordinated through a program to accurately position the bag opening. The two two-finger manipulators are installed at the front end of the frame. Each two-finger manipulator includes two locking handles and two connecting arms and has six degrees of freedom. The two locking handles are of a thin conical structure, with a 10-mm smooth part at the end, and the outer side of the upper part is a non-slip structure with hook-and-loop fiber surface of Velcro. Servos are respectively installed at the joints to control the movement of the connecting arms and the locking handles, so as to realize the micro-opening and knotting of the mesh woven bag.

[0008] The clamping manipulator is installed at the end of the frame and includes two locking handles and two connecting arms and has four degrees of freedom. Servos are respectively installed at the joints to control the movement of the connecting arms and the locking handles, and cooperate with the two-finger manipulators to realize the bag opening of the mesh woven bag.

[0009] The bag-pushing mechanism is characterized by being of a bent-arm structure, installed on both sides of the device, with a diameter of 50 mm. After bagging and sealing, the mesh woven bag filled with crops is pushed inward by the bag-pushing mechanism and slides to the ground through a slideway.

[0010] The beneficial effects of the present invention are as follows: The present invention can complete the work of anti-adhesion, bag opening, bagging, and sealing of the mesh woven bag, and realize the full-automatic packaging of the mesh woven bag. The structure of the present invention is simple and has strong practicability, which can reduce the labor intensity, lower the labor cost, and improve the work efficiency.

[0018] The present invention will be further described below in conjunction with the drawings and embodiments. As Figure 1 shown, the present invention provides an automatic packaging device for mesh woven bags, including a frame 1, a transmission mechanism 2, a bag opening and sealing mechanism 3, a pressure sensor 4, a workbench 5, a bag dialing mechanism 6, and a slide 1-1. The pressure sensor 4 is installed on the workbench 5, and the slide 1-1 is located in the middle of the device.

[0019] As Figure 2 shown, the transmission mechanism 2 is installed at the end of the frame. During operation, the bag ropes of 50 mesh woven bags are sequentially hung at the removable row-type positioning cap 2-3 by manual operation, and the removable row-type positioning cap is adhered to the self-made conveyor belt 2-1 through the magic tape 2-2. The main shaft of the stepper motor 2-4 drives the belt pulley to rotate, and then the self-made conveyor belt 2-1 drives the mesh woven bags to move forward one by one to the reset point of the double-finger manipulator 3-1, and the removable row-type positioning cap 2-3 moves with the self-made conveyor belt 2-1 to form an angle of 45° with the horizontal plane.

[0020] As Figure 3 、 Figure 4 、 Figure 5As shown in the figure, the bag opening and sealing mechanism 3 is installed below the material discharge opening and above the pressure sensor 4. Since the detachable row positioning cap 2-3 moves along with the self-made conveyor belt to form an angle of 45° with the horizontal plane, there is a 10-mm smooth part at the front end of the locking handle 1 of the double-finger manipulator 3-1-1. The mesh woven bag can then slide into the anti-slip structure of the barbed fiber surface 3-1-2 at the upper end of the locking handle 1. The two locking handles of the double-finger manipulator 3-1 are controlled by the servo motor 3-1-3 to horizontally expand the mesh woven bag by a distance of 80 mm. The two locking handles 2 of the clamping manipulator 3-2 are controlled by the servo motor 3-2-2 to vertically expand the mesh woven bag, forming a triangular opening below the material discharge opening. At this time, the electromagnetic switch at the end of the conveyor belt opens the material discharge opening, and the crops can accurately enter the mesh woven bag for collection. When the pressure sensor 4 below the mesh woven bag detects the set weight, the material discharge opening is immediately closed. The two double-finger manipulators 3-1 tighten the bag ropes upward. The locking handle of one double-finger manipulator rotates to the vertical direction, and the locking handle of the other double-finger manipulator remains in the horizontal direction. Due to the rotation of the base of the double-finger manipulator, the two double-finger manipulators approach each other. At this time, the locking handles of the two double-finger manipulators are in a misaligned state with the bag ropes at both ends. The two locking handles 1 are controlled by the servo motor 1 to close and lock the corresponding bag ropes. The two connecting arms of the double-finger manipulator become upright, thus pulling the bag opening closer to complete the knotting of the mesh woven bag and finish the sealing work of the mesh woven bag.

[0021] As Figure 1 shown, the bag pushing mechanism 6 is in the shape of a bent arm and is installed on both sides of the device with a diameter of 50 mm. The mesh woven bag filled with crops is pushed inward by the bag pushing mechanism 6 and slides down to the ground through the slideway 1-1.
