Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a turnover loader for masterbatch production. Background Art

[0002] Masterbatch, also known as masterbatch, is a commonly used raw material in plastics processing. Composed of excess chemical additives, a carrier resin, and a dispersant, masterbatch is used in plastics processing. For ease of operation, the required additives and fillers are first mixed and kneaded with a small amount of carrier resin to produce pellets or powder. In the production of plastic pellets, the raw plastic pellets are poured into a production machine (such as an internal mixer). To do this, the operator must transport the plastic pellets to the production machine, then manually tip the container containing the plastic pellets over and pour the pellets into the machine. In actual production, the container and plastic pellets are heavy, making manual tipping of the container labor-intensive and posing safety risks.

[0003] According to patent publication number CN211566561U, a flip loading machine and flip loading system for the production of plastic masterbatch are disclosed. The flip loading machine includes: a base, the base includes a bottom plate and two vertical rods arranged on opposite sides of the bottom plate; a connecting shaft and a rotating frame, the connecting shaft connects the two vertical rods, and the rotating frame is hinged to the connecting shaft; a driving member, the driving member includes a cylinder and a drive shaft, the cylinder is installed on the bottom plate, and the drive shaft is connected to the rotating frame so that the rotating frame rotates around the connecting shaft under the drive of the driving member. In the above technical solution of the present utility model, the rotating frame is hinged to the connecting shaft, and the driving shaft of the driving member extends out, driving the rotating frame connected to the drive shaft to rotate around the connecting shaft, thereby causing the rotating frame to flip. Powder can be placed in the rotating frame or a container containing powder can be connected to the rotating frame, and the rotating frame flips to pour out the powder. This invention reduces labor intensity, improves work efficiency, and has a high safety factor. The following problems exist in the existing technology:

[0004] In the above-mentioned publication number CN211566561U, due to the influence of humid weather, the masterbatch in the flip loading box is adhered to the bottom, which makes it inconvenient to clean the bottom of the flip loading box during flip loading. At the same time, since the structure of publication number CN211566561U is relatively simple and no protective structure is provided, it is easy to cause collision with the horizontal plate in the vertical rod and the rotating frame when returning to the original position after flipping.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, the utility model provides a flip feeder for masterbatch production, including a base 1, a rectangular array of four mounting holes communicating with each other on the upper surface of the base 1, two fixing frames 2 are fixedly connected on the left and right sides of the upper surface of the base 1, a protective component 3 is fixedly connected to the rear lower side of the two fixing frames 2, a rotating shaft 4 is movably connected to the upper inner part of the two fixing frames 2, a flip feeding box 5 is fixedly connected to the outer surface of the rotating shaft 4, the outer surface of the rotating shaft 4 passes through the outside of the two fixing frames 2 on the left and right sides, two motors 6 are fixedly connected to the upper outer surfaces of the two fixing frames 2 in a mirror-image manner, the output shafts of the two motors 6 are fixedly connected to the two ends of the rotating shaft 4 respectively, two mounting plates are fixedly connected to the lower outer surfaces of the two motors 6, the opposite surfaces of the two mounting plates are fixedly connected to the surfaces of the two fixing frames 2, and an anti-sticking component 7 is provided below the outer surface of the flip feeding box 5;

[0027] When it is needed, the masterbatch is placed in the flip loading box 5, and the motor 6, wires and external power supply are electrically connected to start the flip loading box 5, thereby driving the flip loading box 5 to move and realize the flip operation to achieve loading.

[0028] like Figure 2 The cam 76 is fixedly connected to the upper surface of the lifting box 5, and the upper end of the spring 76 is fixedly connected to the lower surface of the lifting box 5.

[0029] After the material is loaded, the L-shaped plate 71 is pushed to move. Due to the setting of the fixing rod 74, another L-shaped plate 71 is driven. When it moves to the appropriate position, due to the action of the spring 76, the spring plate 72 and the top rod 73 are pulled to slide inside the flip loading box 5 and push the push plate 75 to move. At this time, the spring 76 changes from a stretched state to a contracted state. Due to the elastic action of the spring 76, it will move repeatedly, so that the lower surface of the push plate 75 collides with the bottom of the flip loading box 5 and generates a certain vibration force, thereby effectively preventing the mother material from sticking. When the flip loading is completed, the rotating shaft 4 and the flip loading box 5 are driven by the reverse rotation of the motor 6, so that they return to their original position for the next loading.

[0030] like Figure 3 As shown, sliders 711 are fixedly connected to the upper sides of the vertically opposite surfaces of the two L-shaped plates 71. The horizontal front sides of the two L-shaped plates 71 are each provided with a front-to-back connecting slot 712. The interior of the slot 712 is engaged with the left and right sides of the outer surface of the spring plate 72. The outer surfaces of the sliders 711 are respectively slidably connected to the interior of the slide groove 51.

[0031] The setting of the slider 711 allows it to slide inside the slide groove 51, which facilitates the movement of the L-shaped plate 71. The setting of the slot 712 facilitates the clamping and limiting function of the spring plate 72. When the end is completed, the bracket pulls the spring plate 72 to drive the push rod 73 and the spring 76, and then moves the L-shaped plate 71 to make the slider 711 slide inside the slide groove, so that the slot 712 clamps the spring plate 72.

[0032] like Figure 4 - Figure 5 As shown, the protective assembly 3 includes a box body 31 and an extrusion block 35. A through-hole 32 communicating with the inside and outside is opened on the upper front of the box body 31. A plurality of exhaust ports 33 communicating with the inside and outside are opened on both the left and right ends of the box body 31. A connecting hole 34 communicating with the inside and outside is opened on the upper middle part of the rear side of the box body 31. An air pressure plate 36 is fixedly connected to the rear side of the extrusion block 35. A rubber plate 37 is fixed to the front side of the extrusion block 35. The outer surface of the extrusion block 35 is slidably connected to the inside of the through-hole 32. The outer surface of the air pressure plate 36 is slidably connected to the inside of the box body 31. Square buffer blocks 362 are fixedly connected to the left and right sides of the rear side of the air pressure plate 36. A guide rod 361 is fixed to the middle part of the rear side of the air pressure plate 36. The outer surface of the guide rod 361 is slidably connected to the inside of the connecting hole 34.

[0033] When the flip feeding box 5 is flipped and the feeding is finished and returned to its original position, the air pressure plate 36 is driven to squeeze the rubber plate 37 and the extrusion block 35. Due to the setting of the air pressure plate 36, the air in the box body 31 is squeezed, and the air is discharged through the exhaust port 33, thereby having a buffering effect. The buffering effect is enhanced by the setting of the square buffer block 362 and the rubber plate 37. The setting of the guide rod 361 facilitates the sliding effect inside the connecting hole 34. When the flip feeding box 5 is loading, the air pressure plate 36, the extrusion block 35, and the rubber plate 37 are driven to move by pushing the guide rod 361. At the same time, the outside air is set into the box body 31 through the setting of the exhaust port 33, thereby achieving the next buffering protection effect.

[0034] The following is a detailed description of the working principle of the flip loader used in masterbatch production.

[0035] After the loading box 5 is turned over and loaded, the slider 711 is pushed in the L-shaped plate 71 to slide inside the slide groove 51. When it moves to the appropriate position, due to the action of spring 76, the spring plate 72 and the push rod 73 are pulled to slide inside the flip loading box 5 and push the push plate 75 to move. Due to the elastic action of spring 76, it will move repeatedly, so that the lower surface of the push plate 75 collides with the bottom of the flip loading box 5 and generates a certain vibration force, thereby effectively preventing the masterbatch from sticking. When the flip loading box 5 is turned over and loaded and returns to its original position, it squeezes the rubber plate 37 and the extrusion block 35, thereby driving the air pressure plate 36. Due to the setting of the air pressure plate 36, the air in the box body 31 is squeezed, and the air is discharged through the exhaust port 33, thereby having a buffering effect.

[0036] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
