Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device for automatically grabbing bags and feeding materials. Background Art

[0002] During the processing of EVA film, EVA particles need to be fed into a mixer, and then chemical additives are added to the mixer. After being stirred and mixed by the mixer, the particles are added to an extruder for cast film formation. EVA particles are usually fed manually. During the manual feeding process, EVA particles are transferred to the feed inlet of the mixer by manpower, and the staff use a sharp tool to cut the packaging bag of the EVA particles and pour the EVA particles in the bag into the mixer, which results in prolonged feeding time and reduced production efficiency of EVA film. At the same time, most of the packaging bags of EVA particles are woven bags. When feeding, the woven bags need to be cut to pour out the materials. Some EVA particles will remain in the packaging bags, and the discharge is incomplete, resulting in waste. When manually using a sharp tool to cut the packaging bag containing EVA particles, the sharp tool may cause harm to the human body. While causing work-related accidents, the blood from the wound mixes with the EVA particles, causing pollution to the raw materials for EVA film production. Utility Model Content

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0023] An embodiment of the present application provides a feeding device for automatic bag grabbing and feeding, which can place bagged raw materials on a conveyor chain, and the bagged raw materials are moved to a specified position along the conveyor chain. The bagged raw materials on the conveyor chain can be positioned by a positioning component, so that a mechanical gripper can accurately grab the bagged raw materials and move them to the feeding barrel of the machine.

[0024] The automatic bag grabbing and feeding feeding device is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0025] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Example 1

[0027] See also Figure 1-8 In the embodiment, an automatic bag grabbing and feeding feeding device is provided, comprising: a gantry 1, an electric slide rail 11 is fixedly installed on the top of the gantry 1, a mechanical gripper 12 is fixedly installed on the bottom of the slide platform of the electric slide rail 11, a conveyor chain 13 is provided below the gantry 1, a recycling box 14 is provided on one side of the conveyor chain 13, a positioning component is arranged on the top of the conveyor chain 13, and is used to position the raw materials, and a material pouring component is arranged on the inner side of the gantry 1, and is used to pour out the raw materials in the bag.

[0028] During processing, the bagged raw materials are placed on the conveyor chain 13 respectively, and the bagged raw materials are moved to the specified position along with the conveyor chain 13. The bagged raw materials on the conveyor chain can be positioned by the positioning component, so that the mechanical gripper 12 can accurately grab the bagged raw materials and move them to the feeding barrel of the machine. The mechanical gripper 12 is driven by the electric slide rail 11 to move horizontally, and the raw materials are emptied out through the pouring component. When pouring, the bag is fixed to prevent the bag from being stuck in the feeding barrel during pouring. The frame 3 is opened to both sides to make the bag V-shaped, so that the residual raw materials in the bag can slide out. After pouring, the mechanical gripper 12 grabs the empty bag and moves it to the recycling box 14. The mechanical gripper 12 is fully opened to let the bag fall into the recycling box 14.

[0029] Example 2

[0030] On the basis of Example 1, the positioning component includes: two symmetrically arranged guide plates 2 above the conveying chain 13, a plurality of rolling rollers 21 are respectively provided on the opposite sides of the two guide plates 2, a limit rod 22 is fixedly installed on the top of the conveying chain 13, a contact sensor 23 is provided on the side of the limit rod 22 facing the guide plate 2, and a fixed frame 24 is respectively fixedly installed on the top of the two conveying chains 13, and sliders 25 are respectively slidably connected inside the two fixed frames 24, and threaded holes are opened on the sliders 25, and threaded screws a26 are threadedly connected inside the threaded holes, and one end of the threaded screw a26 is rotatably connected to the guide plate 2, and guide grooves 27 are respectively opened on the inner walls on the opposite sides of the fixed frame 24, and two guide blocks 28 are respectively provided inside the guide grooves 27, and one side of the two guide blocks 28 is respectively connected to the slider 25, and a threaded screw b29 is threadedly connected to the top of the fixed frame 24, and the bottom end of the threaded screw b29 is rotatably connected to the slider 25.

[0031] The bagged materials move to the position of the two guide plates 2 along with the conveyor chain 13. One side of the two guide plates 2 is provided with a trumpet-shaped structure, so that the bagged materials in a bad position state rotate when they touch the guide plates 2. The rolling rollers 21 provided on the opposite sides of the two guide plates 2 prevent the bagged materials from getting stuck and can also make the bagged materials rotate more smoothly, thereby adjusting the state of the bagged materials so that they can pass through the two guide plates 2 smoothly. The distance between the two guide plates 2 is just enough for the bagged materials to pass through. The bagged materials that have entered continue to move until they are restricted. The bagged materials are blocked by the positioning rod 22. At this time, the bagged materials touch the contact sensor 23. After the contact sensor 23 receives the signal, the conveyor chain 13 stops working, thereby preventing the bagged materials from catching up and causing squeezing. At this time, the bagged materials are in the best state. The mechanical gripper 12 moves to the top of it to grab it. After the bagged materials are grabbed, the contact sensor 23 senses that the bagged materials have moved away and starts the conveyor chain 13 again. The conveyor chain 13 conveys the bagged materials to the grabbing area, thereby positioning the bagged materials and facilitating the mechanical gripper 12 to accurately grab the bagged materials.

[0032] When facing some smaller bags of bagged materials, it is necessary to adjust the distance between the two guide plates 2 according to their specific sizes. At this time, the threaded screw a26 is rotated to engage with the slider 25. Since the slider 25 is restricted by the guide blocks 28 on both sides, it can only move along the direction of the guide blocks 28. Therefore, the threaded engagement will drive the threaded screw a26 to move horizontally. When the threaded screw a26 moves, it drives the guide plate 2 to move at the same time, so as to adjust the distance between the two guide plates 2. By controlling the rotation direction of the guide plate 2, the threaded screw a26 can be moved to the left or right. If the thickness of the bagged materials is different, it is necessary to adjust the height of the guide plate 2 so that the middle position of the two guide plates 2 is just in contact with the protrusions on both sides of the bagged materials. At this time, the threaded screw b29 is rotated. The same principle makes the threaded screw b29 drive the slider 25 to move up and down, and the slider 25 drives the threaded screw a26 and the guide plate 2 to move, so as to adjust the height position of the guide plate 2.

[0033] Among them, a mounting platform 4 is fixedly installed on the inner wall of the gantry 1 away from the conveyor chain 13, a connecting rod 41 is fixedly installed on the top of the mounting platform 4, and a mounting block 42 is fixedly installed on the upper surface of the connecting rod 41 away from one end of the mounting platform 4, and a blade 43 is provided inside the mounting block 42.

[0034] Before use, the mounting platform 4 is mounted on the gantry 1, and the mounting block 42 is located directly above the feeding barrel. The mechanical gripper 12 grabs the bagged raw materials and moves them toward the feeding barrel. During the movement, the lower surface of the bagged materials slides over the blade 43, thereby cutting the bagged materials.

[0035] Example 3

[0036] On the basis of Example 1, the material unloading assembly includes: frames 3 fixedly installed on the grabbing arms on both sides of the mechanical gripper 12, a plurality of support rods 31 are fixedly connected to the opposite sides of the bottom of the two frames 3, the plurality of support rods 31 on both sides are arranged to be inclined toward the center, surrounding rods 32 fixedly connected to the opposite sides of the two frames 3, cone thorns 33 are respectively arranged on the upper surface of the plurality of support rods 31, and the plurality of support rods 31 are respectively provided with storage grooves 34, and pneumatic rods 35 are fixedly installed inside the storage grooves 34, and the top of the pneumatic rod 35 is connected to the cone thorn 33.

[0037] When the bottom of the bagged material is cut open, the raw materials inside flow out from the opening. The raw materials above the opening flow out first, followed by the raw materials on both sides of the opening. The raw materials at the bottom have a smaller angle with the opening, so the raw materials on both sides of the opening cannot be completely discharged. At this time, the grabbing arms on both sides of the mechanical gripper 12 slightly open and close to both sides, driving the frame 3 to form a triangular structure. The mechanical gripper 12 grabs the cone thorns 33 at the bottom and inserts them into the bag. Therefore, the bag is constrained on multiple support rods 31, and the surrounding rods 32 can prevent the bagged material from sliding off from both sides, thereby preventing the bag from being driven together when the raw material block is emptied. The frame 3 moves, causing the bag to fall into the feeding barrel. When the frame 3 moves, the support rod 31 at the bottom is driven to move at the same time, so that the bag is bent into a V-shaped state. The raw materials on both sides are inclined more to the opening. Under the action of gravity, the raw materials flow to the opening for discharge, so that the raw materials in the bag are emptied. After the feeding is completed, the mechanical gripper 12 moves the empty bag to the recycling box 14, and then the pneumatic rod 35 drives the cone thorn 33 to retract into the receiving groove 34, so that the bag loses its restraint, and then the mechanical gripper 12 is fully opened, and the bag is loosened and naturally falls into the recycling box 14, so that the packaging bag can be collected.
