Description

Technical Field

[0001] The invention relates to the technical field of rubber and plastic flange production and feeding, in particular to a feeding machine for producing rubber and plastic flanges for flexible air ducts. Background Art

[0002] Flexible air ducts are made of corrosion-resistant, airtight and mildew-resistant flexible materials. They are mainly used to transport air or discharge exhaust gas. In order to ensure the sealing of the flexible air duct when connected with other pipes or ventilation equipment, the flexible air duct needs to be docked and fixed with rubber-plastic flanges. When producing rubber-plastic flanges for flexible air ducts, a feeder is needed to feed the granular rubber-plastic raw materials into the processing equipment, and then the rubber particles are heated and formed into rubber-plastic flanges for flexible air ducts.

[0003] When using the existing flexible duct rubber flange and rubber-plastic flange feeding machine, the staff is required to manually use a blade to cut the rubber and plastic particle packaging, and then pour it into the storage barrel of the flexible duct rubber flange and rubber-plastic flange feeding machine. The rubber and plastic particle packaging bag cannot be quickly and automatically cut open, which makes the filling work of the flexible duct rubber flange and rubber-plastic flange feeding machine more time-consuming and labor-intensive. At the same time, it is also easy to cause the rubber and plastic particles to scatter during the feeding process, affecting the feeding convenience of the flexible duct rubber flange and rubber-plastic flange feeding machine.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing feeding machine for the production of rubber and plastic flanges for flexible air ducts, and even if it can be solved, it needs to be solved through the cooperation of external tools, which makes it impossible to achieve the desired effect.

[0042] The specific implementation method of this embodiment is as follows: when in use, first connect the servo motor 15 and the rotating motor 2105 to the external power supply and the controller. When it is necessary to add the bagged rubber and plastic particles into the collecting hopper 11 to prepare for the subsequent production and loading of the flexible air duct rubber and plastic flange, it is only necessary to place the rubber and plastic particle packaging bag on the rotating roller 2103.

The inner wall of each second bevel gear 2206 is fixedly connected with a connecting column 2207. Each connecting column 2207 is rotatably connected to the inside of the limiting frame 2218. Two conveyor belts 2208 are provided above the collecting hopper 11. The outer surface of each connecting column 2207 is in contact with the inner wall of the conveyor belt 2208.

By setting the bag discharge unit 22, the empty rubber and plastic granule packaging bag that has been dumped can be pulled out by utilizing the rotation of the conveyor belt 2208 in conjunction with the spikes 2209, so as to prevent the rubber and plastic granule packaging bag from falling into the collecting hopper 11, so that the discharge work of the rubber and plastic granule packaging bag also does not require the staff to manually take it, and only needs to regularly collect the discharged rubber and plastic granule packaging bags, which ensures that the rubber and plastic granule packaging bags can be quickly cut open while preventing the rubber and plastic granule packaging bags from being easily mixed with the plastic granules in the collecting hopper 11;

The meshing relationship between the first bevel gear 2205 and the second bevel gear 2206 can be used to drive the connecting column 2207 to rotate, so that the two conveyor belts 2208 can rotate at the same time. By combining the rotation of the conveyor belt 2208 and the spikes 2209, the spikes 2209 can be used to move the rubber and plastic granule packaging bags that have been discharged until the rubber and plastic granule packaging bags move backwards to contact the separation plate 2217. The rubber and plastic granule packaging bags can be separated from the conveyor belt 2208 and the spikes 2209 by the separation plate 2217, and guided outward by the guide plate 2216 to other positions to be completely separated from the collecting hopper 11, so as to prevent the rubber and plastic granule packaging bags from falling into the collecting hopper 11, so that the discharge work of the rubber and plastic granule packaging bags also does not require manual picking up by the staff, and only the discharged rubber and plastic granule packaging bags need to be collected regularly. While ensuring that the rubber and plastic granule packaging bags can be quickly cut open, the rubber and plastic granule packaging bags are not easily mixed with the plastic granules in the collecting hopper 11.

[0048] As a further limitation of the shaking mechanism 3 of the present invention, the shaking mechanism 3 includes two stable frames 301, the opposite sides of the two stable frames 301 are respectively fixedly connected to the two side surfaces of the collecting hopper 11, the opposite sides of the two stable frames 301 are fixedly connected with protective plates 302, the opposite sides of the two rotating motors 2210 are respectively fixedly connected to the side surfaces of the two protective plates 302 that are away from each other, and the opposite sides of the two protective plates 302 are respectively provided with two sliding grooves 303, each connecting column 2207 is slidably connected to the inside of the sliding groove 303, and the two conveyor belts 2208 are fixedly connected to the two sides of the two protective plates 302. The outer surface of each of the two fixed plates 2201 is provided with a plurality of leakage openings 304, a movable plate 305 is provided above each of the two fixed plates 2201, one side of each of the limit frames 2218 is fixedly connected to one side of the movable plate 305, the bottom surfaces of the two movable plates 305 are fixedly connected with a plurality of return springs 306, the other ends of the plurality of return springs 306 are fixedly connected to the upper surface of the fixed plate 2201, a second telescopic rod 307 is provided inside each of the plurality of return springs 306, and the telescopic end of each second telescopic rod 307 is fixed to the bottom surface of the movable plate 305 The bottom end of each second telescopic rod 307 is fixedly connected to the upper surface of the stabilizing plate 2201, the outer surface of each rotating column 2202 is fixedly connected to a rotating disk 308, the upper surface of each rotating disk 308 is an inclined surface, the interior of each limiting frame 2218 is fixedly inlaid with an auxiliary bearing 309, the inner wall of the inner ring of each auxiliary bearing 309 is fixedly connected to the outer surface of the first bevel gear 2205, the bottom surface of each limiting frame 2218 is fixedly connected to a limiting seat 310, and the interior of each limiting seat 310 is rotatably connected to a roller 311 The outer surface of each roller 311 is in contact with the upper surface of the rotating disk 308. By setting the shaking mechanism 3, the rubber and plastic particle packaging bag can be shaken in cooperation with the bag body discharge unit 22 during the rubber and plastic particle packaging bag discharge process, so that a small amount of rubber and plastic particles remaining in the rubber and plastic particle packaging bag can be better dropped from the inside of the rubber and plastic particle packaging bag into the collecting hopper 11, so that the problem of rubber and plastic particles scattering is less likely to occur during the feeding process of the flexible air duct rubber flange rubber and plastic flange feeding machine, so that the plastic particles in the rubber and plastic particle packaging bag can be more fully dumped;

[0049] Two bearing seats 312 are fixedly connected to the upper surfaces of the two stabilizing frames 301. The inner wall of each bearing seat 312 is rotatably connected to the outer surface of the transmission rod 2211. The bearing seat 312 can limit the position of the transmission rod 2211 without affecting the normal rotation of the transmission rod 2211, thereby ensuring the normal power transmission of the transmission rod 2211.

[0050] The specific implementation of this embodiment is as follows: the stabilizing frame 301 is used in conjunction with the protective plate 302 to prevent the rubber and plastic particles from scattering outward from the side. When the rotating column 2202 rotates, the rotating disk 308 can be driven to rotate. At this time, the inclined surface of the rotating disk 308 is used in conjunction with the rolling of the limit seat 310 and the roller 311 to force the limit frame 2218 to move up and down. When the limit frame 2218 moves up and down, it can drive the connecting column 2207, the second bevel gear 2206 and the first bevel gear 2205 to move up and down. Since the auxiliary bearing 309 can fix the first bevel gear 2205 The position of the limit frame 2218 and the rectangular shape of the rectangular block 2203 can drive the first bevel gear 2205 to keep rotating during the up and down movement without affecting the up and down movement of the first bevel gear 2205, and the sliding groove 303 can be used to limit the connecting column 2207, and the connecting column 2207 can be prevented from rotating horizontally without affecting the up and down movement of the connecting column 2207. At the same time, the rotating column 2202 rotates inside the stabilizing plate 2201, so during the up and down movement of the limit frame 2218, it will move up and down on the rotating column 2202 and the sliding column 2204. When the limit frame 2218 drives the connecting column 2207 to move up and down, the conveyor belt 2208 can be driven to shake up and down. At this time, the rubber and plastic granule packaging bag on the conveyor belt 2208 can be shaken, so that the rubber and plastic granule packaging bag can pass through the gap between the two conveyor belts 2208 and the leakage port 304 and fall into the collecting hopper 11, making it less likely for the rubber and plastic granule packaging bag to fall into the collecting hopper 11 during the feeding process of the flexible air duct rubber flange rubber flange feeding machine. The plastic particles in the bag can be poured more fully, and even if a small amount of rubber and plastic particles fall out, they will fall into the collecting rack 2214, and finally be discharged into the collecting hopper 11 through the collecting rack 2214. At the same time, when the limit rack 2218 moves up and down, the movable plate 305 can drive the return spring 306 to stretch under the limit of the second telescopic rod 307, and then the return spring 306 can assist the limit rack 2218 to return downward, and force the roller 311 to always keep in contact with the upper surface of the rotating disk 308, thereby further ensuring the continuous shaking of the rubber and plastic particle packaging bag.
