Description

Technical Field

[0001] The present invention relates to the technical field of safe production equipment, and in particular to a circulating solid packaging woven bag unpacking device and a method thereof. Background Art

[0002] In industrial production, due to the special dangers of certain raw materials and production workshops, there must be a certain safety distance and inventory between warehouses and workshops. During normal production, it is necessary to transport woven bag packaging in batches over long distances to the production workshop for feeding process through manual or special facilities to ensure normal production, ensure the safety distance between dangerous buildings, and ensure that dangerous materials in each building are not over-stocked.

[0003] However, the production process requires a large amount of manual handling and unpacking of 40-50kg / bag of bagged raw materials for feeding. This manual handling and unpacking of woven bags is labor-intensive and detrimental to energy conservation, environmental protection, and the development of artificial intelligence. Currently, specialized conveyor belts are used to handle material handling from the warehouse to the production workshop. However, this still relies on manual labor to move each piece of material to the feeding port and then unpack and feed it. This is labor-intensive, unsustainable, and unhealthy.

[0010] The collecting mechanism includes a support frame, on which a horizontal bracket is installed. The horizontal bracket cooperates with the material bag, and the height of the horizontal bracket is lower than the height of the connecting rod. When the material bag moves through the pushing mechanism and half of the material bag passes through the horizontal bracket, the manipulator opens and the empty material bag is hung on the horizontal bracket.

[0011] A collecting rack perpendicular to the material bag is also installed on the horizontal bracket. The height of the collecting rack is lower than the height of the connecting rod, and the end is a sharp conical structure. When the material bag moves to the collecting rack through the pushing mechanism, the empty material bag passes through the collecting rack, the pushing mechanism stops moving, the manipulator opens, and the empty material bag is hung on the collecting rack.

[0012] The manipulator is installed on the connecting rod. The manipulator is a compressed air driven manipulator. The manipulator is connected to a photoelectric switch for controlling opening and closing.

[0013] The cutting tool is a herringbone structure and is arranged below the hanging mechanism. When the material bag reaches the hanging mechanism, the end of the material bag contacts the cutting tool and is pushed by the pushing mechanism to complete the cutting.

[0015] A method for unpacking a circulating solid packaging woven bag device, comprising:

[0016] 1) The material bag moves to the guide plate through the transmission belt;

[0017] 2) The guide plate guides the material bag into the bag, the hanging mechanism grabs the end of the material bag through the manipulator, and then the pushing mechanism starts to move, driving the hanging mechanism to move, and the cutting tool under the hanging mechanism cuts the material bag;

[0018] 3) When the pushing mechanism brings the material bag to the end, the material continues to fall and the unloading is completed.

DETAILED DESCRIPTION

[0027] The present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the embodiments described herein are only some embodiments of the present invention, not all embodiments. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0028] like Figure 1 、 2As shown, the present invention provides a circulating solid packaging woven bag unpacking device, comprising a bracket 1, on which is disposed a guide plate 2, the end of which is provided with a curved structure that matches the end of a conveyor belt. The guide plate 2 is disposed at the end of the conveyor belt, and movable pushing mechanisms 3 are symmetrically disposed on both sides of the guide plate 2. The pushing mechanism 3 is mounted with a hanging mechanism 5 for fixing a material bag 4, and a cutting tool 6 is mounted below the hanging mechanism 5. The hanging mechanism 5 includes an openable and closable manipulator 51, which is mounted on the pushing mechanism 3. When the material bag 4 reaches the end of the conveyor belt, the manipulator 51 closes, grasping one end of the material bag 4, and the other end of the material bag 4 contacts the cutting tool 6.

[0029] Furthermore, in order to collect the materials in a timely manner and facilitate the staff to carry out the next operation, a base 7 for collecting materials is installed under the pushing mechanism 3 in the present invention, one end of the base 7 is connected to the guide plate 2, and the other end is connected to the feeding end; the base 7 is a vibrating screen base, and the base 7 is a trapezoidal gradually lowering structure, which is convenient for material collection.

[0030] like Figure 3 As shown, the pushing mechanism 3 includes slide rails 31 symmetrically arranged on both sides of the guide plate 2, and sliders 32 are installed on the slide rails 31. The sliders 32 are connected to a power device, and connecting rods 33 are installed between the sliders 32.

The output end of the linear cylinder is connected to the slider 32. Limit switches 34 are installed at the starting point and end point of the linear cylinder.

[0032] Further preferably, in the present invention, the collection mechanism includes a support frame 8, mounted with a horizontal support 9, which cooperates with the material bag 4 and is lower than the height of the connecting rod 33. When the material bag 4 is moved by the pushing mechanism 3 and halfway through the horizontal support 9, the manipulator 51 opens and the empty material bag 4 is hung on the horizontal support 9. This structure helps workers quickly organize and collect the material bags 4, saving time and improving work efficiency. For example, in the present invention, another method for collecting the material bags 4 is provided in which the horizontal support 9 is further mounted with a collection rack 10 perpendicular to the material bag 4, lower than the height of the connecting rod 33, and with a sharp, tapered end. When the material bag 4 is moved by the pushing mechanism 3 to the collection rack 10, the empty material bag 4 passes through the collection rack 10, the pushing mechanism 3 stops, the manipulator 51 opens, and the empty material bag 4 is hung on the collection rack 10. Each time the empty material bag 4 passes through the collecting rack 10 , it is penetrated by the collecting rack 10 , and each material bag can be threaded together, making it convenient for the staff to sort them out.

[0033] It should be noted that the manipulator 51 of the present invention is installed on the connecting rod 33. The manipulator 51 is a compressed air driven manipulator. The manipulator 51 is connected to a photoelectric switch 52 for controlling opening and closing.

[0034] Preferably, if Figure 5 As shown, in order to fully cut the bottom of the material bag 4, the cutting tool 6 is a herringbone structure and is arranged below the hanging mechanism 5. When the material bag 4 reaches the hanging mechanism 5, the end of the material bag contacts the cutting tool 6 and is pushed by the pushing mechanism 3 to complete the cutting.

[0035] The present invention also provides a method for unpacking a circulating solid packaging woven bag, comprising:

[0036] 1) The material bag 4 moves to the guide plate 2 via the transmission belt;

[0037] 2) The guide plate 2 guides the material bag 4, and the hanging mechanism 5 grabs the end of the material bag 4 through the manipulator 51. Then the pushing mechanism 3 starts to move, driving the hanging mechanism 5 to move. The cutting tool 6 below the hanging mechanism 5 cuts the material bag 4;

[0038] 3) When the pushing mechanism 3 brings the material bag 4 to the end, the material continues to fall and the unloading is completed.

[0039] It is obvious to those skilled in the art that the above-mentioned specific examples are only preferred embodiments of the present invention. Therefore, any improvements and changes that may be made by those skilled in the art to certain parts of the present invention still reflect the principles of the present invention and achieve the purpose of the present invention, and all fall within the scope of protection of the present invention.
