Abstract

This utility model relates to an automatic feeding device for enhancing the permeability of masterbatch. A placement frame is rotatably mounted on the top of a fixed base. A discharge trough is opened on the top side of the placement frame. Support frames are fixedly installed on both sides of the top center of the placement frame. An installation frame is movably mounted on the top center of the placement frame. Transmission plates are horizontally fixedly mounted on both ends of the outer side of the installation frame. The installation frame and transmission plates are located on the inner side of the support frames below. A synchronous rotation mechanism is set inside the installation frame. Four sets of transmission frames are fixedly mounted on the outer side of the installation frame. This utility model can drive the four sets of abutment plates to move synchronously and relative to each other inside the bag opening until they are in contact with the inner wall of the bag opening and continuously abut against the bag opening.

This provides a stable guarantee for the feeding rate of the masterbatch during extrusion processing.

Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology, specifically an automatic feeding device for permeability enhancement masterbatch. Background Technology

[0002] Antireflective masterbatch is a functional additive specifically for optical materials. It uses a polymer resin as a carrier and integrates antireflective components through nanoscale dispersion technology. After addition, it can significantly reduce the surface reflectivity of materials and improve light transmittance. It is widely used in photovoltaic panels, displays, optical lenses and other fields. When processing antireflective masterbatch, a corresponding screw extruder is used. After various raw materials are fed into the feed port, they are thermally mixed and shaped by the extruder.

[0003] In traditional extruders, when extrudeing masterbatch, various raw materials are stored wrapped in plastic bags. When adding materials, the operator places the bags on a tilting mechanism to dispose of them. However, after opening the bags, the openings of bags of different sizes cannot be secured. This leads to deformation of the bag openings due to material pressure during disposition, resulting in a reduced opening diameter. This affects disposition efficiency, lowers the material feeding rate, and ultimately impacts the extrusion efficiency of the masterbatch. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide an automatic feeding device for enhancing masterbatch. This addresses the problem that when extruding enhancing masterbatch in a current extruder, various raw materials are stored in plastic bags. When adding raw materials, the operator places the bags on the surface of a turning mechanism to pour them out. However, after opening the bags and placing them on the turning mechanism, the openings of bags of different sizes cannot be fixed. This leads to the bag openings being easily deformed by the material during pouring, resulting in a reduced opening diameter, affecting the pouring efficiency, and thus reducing the material feeding rate and the extrusion processing efficiency of the enhancing masterbatch.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design an automatic feeding device for enhancing transparency masterbatch, including a fixed base, a placement frame rotatably provided on the top of the fixed base, a discharge groove opened on the top side of the placement frame, and support frames fixedly installed on both sides of the top center of the placement frame.

[0006] A mounting frame is movably provided at the top center of the placement frame. Transmission plates are horizontally fixed at both ends of the outer side of the mounting frame, and both the mounting frame and the transmission plates are located below the inner side of the support frame. A synchronous rotation mechanism is provided inside the mounting frame.

[0007] Four sets of transmission frames are fixedly installed on the outside of the mounting frame. The four sets of transmission frames are arranged diagonally on the outer wall of the mounting frame and are located below the transmission plate. Each transmission frame is equipped with a drive mechanism, and the synchronous rotation mechanism and the drive mechanism are connected in transmission.

[0008] Preferably, support plates are vertically fixedly installed on both sides of the top of the fixed base, the outer wall of the placement frame is rotatably installed inside the support plate through bearings, and a drive motor is fixedly installed on the top side of the support plate, and the drive motor transmission shaft is connected to the outer wall of the placement frame.

[0009] Preferably, a guide plate is fixedly installed on the top outer wall of the placement frame, and baffle plates are fixedly installed on both sides of the top of the guide plate. Both the guide plate and the baffle plates are located outside the discharge trough.

[0010] Preferably, the driving mechanism includes a rotating lead screw and an abutment plate. The rotating lead screw is rotatably mounted inside each transmission frame via a bearing. A movable sleeve is threadedly connected to the outside of each rotating lead screw. A connecting block is vertically fixedly mounted on the top of the outside of each movable sleeve. A sliding frame is slidably sleeved on the outside of the transmission frame, and the top of the connecting block is fixedly connected to the top of the inner wall of the sliding frame.

[0011] Preferably, each of the sliding frames has a connecting column fixedly installed vertically on both sides of its bottom, an abutment plate is fixedly installed between the bottom ends of every two sets of connecting columns, and a limit groove is opened at the top center of each transmission frame, with the top of the connecting block slidingly installed inside the limit groove.

[0012] Preferably, the synchronous rotation mechanism includes a transmission bevel gear and a follower bevel gear. Each of the rotating screws has a rotating rod fixedly installed on the side near the mounting frame. The follower bevel gear is fixedly sleeved on the outer side wall of each rotating rod. A transmission shaft is vertically rotatably installed at the top center of the mounting frame via a bearing. The transmission bevel gear is fixedly sleeved at the bottom of the transmission shaft, and the transmission bevel gear and the follower bevel gear mesh with each other.

[0013] Preferably, a servo motor is fixedly installed at the top center of the mounting frame, and the bottom of the servo motor drive shaft is fixedly connected to the top of the drive shaft rod via a coupling.

[0014] Preferably, an electric actuator is vertically fixedly installed at the top center of the support frame, and the bottom of the electric actuator's drive shaft is fixedly connected to the top surface of the transmission plate. A guide slider is fixedly installed on the side of the transmission plate. Guide grooves are vertically opened on the inner sides of both the support frame and the placement frame, and the guide slider is slidably installed inside the guide groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model features a rotatable placement frame on a fixed base surface, an mounting frame on top of the placement frame via a support frame, and a transmission frame diagonally positioned on the outer side of the mounting frame. When it is necessary to pour bagged raw materials and fix the bag opening, the operator only needs to start the servo motor, causing it to rotate and drive the transmission bevel gear inside the mounting frame to rotate. Through the meshing transmission of the transmission bevel gear and the follower bevel gear, the follower bevel gears on the four sides inside the mounting frame rotate synchronously. The rotating rod then connects the follower bevel gears and the rotating screw, allowing the transmission bevel gears on the outer side of the mounting frame to rotate synchronously. The four sets of rotating screws on the corner rotate synchronously. Combined with the rotational transmission of the rotating screws to the movable sleeves, the four sets of movable sleeves can move synchronously relative to each other outside the mounting frame. Under the connection and transmission of the connecting block and the sliding frame, they can drive the four sets of abutting plates to move synchronously relative to each other inside the bag opening until they are in contact with the inner wall of the bag opening and continuously abut against the bag opening. This keeps the bag opening in a fixed and open state, preventing the raw material from squeezing the bag opening during the turning and pouring process, causing it to deform and shrink the inner diameter, which would affect the pouring rate of the raw material. This provides a stable guarantee for the feeding rate during the extrusion processing of the permeation masterbatch.

[0017] 2. This utility model, by providing an electric push rod at the top of the support frame and a guide slider on the side of the transmission plate, allows the electric push rod to provide a corresponding vertical pushing force to the transmission plate during operation. Combined with the vertical guiding effect of the guide groove on the guide slider, the two sets of transmission plates can drive the mounting frame and the transmission frame to move vertically at the top of the placement frame simultaneously, adjusting the vertical position of the abutment plate. Thus, when feeding raw materials into bags of different specifications, the abutment plate can adhere to the inner wall of the bag opening and fix it open, improving the applicability of the overall feeding mechanism.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] Example 1: An automatic feeding device for a permeability enhancement masterbatch, see [link to example]. Figures 1 to 4 Support frames 2 are fixedly installed on both sides of the top center of the placement frame 13. An installation frame 22 is movably installed in the top center of the placement frame 13. Transmission plates 21 are horizontally fixedly installed on both sides of the outer side of the installation frame 22. The installation frame 22 and the transmission plate 21 are both located on the inner side of the support frame 2. An electric push rod 5 is vertically fixedly installed at the top center of the support frame 2. The bottom of the transmission shaft 32 of the electric push rod 5 is fixedly connected to the top surface of the transmission plate 21. The two sets of electric push rods 5 are electrically connected to the external PLC controller. With the synchronous control function of the PLC controller, the synchronous start and stop control of the two sets of electric push rods 5 can be realized. A guide slider 41 is fixedly installed on the side of the transmission plate 21. The support frame 2 and the placement frame 13 are both vertically provided with guide grooves 4. The guide slider 41 is slidably installed inside the guide groove 4. The cross-section of the guide slider 41 and the guide groove 4 are both T-shaped, which can ensure that while the guide slider 41 moves vertically inside the guide groove 4, the guide slider 41 will not move laterally and move out of the guide groove 4.

[0025] When feeding the extruded raw material for the permeation masterbatch, the raw material bag is placed vertically inside the placement frame 13, and then the bag opening is opened. Subsequently, the electric push rod 5 is started synchronously through the external PLC controller, so that it provides the corresponding vertical pushing force to the transmission plate 21. Under the guidance of the guide slide 4 and the guide slider 41, the transmission plate 21 moves vertically downward synchronously inside the support frame 2, thereby driving the mounting frame 22 and the transmission frame 23. The abutment plate 29 at the bottom of the transmission frame 23 moves vertically synchronously, so that the abutment plate 29 moves and inserts into the bag opening of the raw material packaging bag, which facilitates the subsequent fixing and opening of the bag opening after the abutment plate 29 is adjusted.

[0026] For details, see Figures 1 to 4 A mounting frame 22 is movably installed at the top center of the placement frame 13. A rotating rod 3 is fixedly installed on the side of each rotating screw 24 near the mounting frame 22. The rotating rod 3 extends from the side of the transmission frame 23 to the inside of the mounting frame 22 through a bearing. A servo motor 35 is fixedly installed at the top center of the mounting frame 22. The bottom of the transmission shaft of the servo motor 35 is fixedly connected to the top of the transmission shaft rod 32 through a coupling. A follower bevel gear 31 is fixedly sleeved on the outer wall of each rotating rod 3. A transmission shaft rod 32 is vertically rotatably installed at the top center of the mounting frame 22 through a bearing. A transmission bevel gear 33 is fixedly sleeved on the bottom of the transmission shaft rod 32, and the transmission bevel gear 33 and the follower bevel gear 31 mesh with each other.

[0027] After the vertical position of the abutment plate 29 is adjusted to be inside the bag opening, the servo motor 35 is turned on by the external controller, so that it runs and provides the corresponding rotational driving force to the transmission shaft 3. This drives the transmission bevel gear 33 to rotate synchronously on the top of the inner side of the mounting frame 22. Under the meshing transmission action of the transmission bevel gear 33 and the follower bevel gear 31, the four sets of follower bevel gear 31 can be provided with synchronous driving force. After the follower bevel gear 31 rotates synchronously inside the mounting frame 22, it can then provide the driving force required for the synchronous adjustment of the four sets of abutment plates 29 under the connecting transmission action of the transmission shaft 32. This allows the four sets of abutment plates 29 to move horizontally synchronously and fix and open the bag opening of the packaging bag.

[0028] Further, see Figures 1 to 4 Four sets of transmission frames 23 are fixedly installed on the outside of the mounting frame 22. The four sets of transmission frames 23 are arranged diagonally on the outer wall of the mounting frame 22, and the transmission frames 23 are located below the transmission plate 21. Each transmission frame 23 has a rotating screw 24 installed inside through a bearing. Each rotating screw 24 has a movable sleeve 25 connected to its outer side through a thread. Each movable sleeve 25 has a connecting block 26 fixedly installed vertically on its outer top. A sliding frame 27 is slidably sleeved on the outside of the transmission frame 23, and the top of the connecting block 26 is fixedly connected to the top of the inner wall of the sliding frame 27.

[0029] Further, see Figures 1 to 4 Each sliding frame 27 has a connecting column 28 fixedly installed vertically on both sides of its bottom. An abutment plate 29 is fixedly installed between the bottom ends of every two sets of connecting columns 28. Each transmission frame 23 has a limiting groove 34 opened at the top center. The top of the connecting block 26 is slidably installed inside the limiting groove 34. The limiting groove 34 is opened at the top of the transmission frame 23, so that when the placement frame 13 rotates and tilts the bagged material, the transmission frame 23 will also rotate accordingly to ensure that the material will not roll through the limiting groove 34 into the transmission frame 23 and obstruct the transmission of the rotating screw 24 and the movable sleeve 25.

[0030] After the four sets of follower bevel teeth 31 rotate synchronously driven by the transmission bevel teeth 33, the transmission shaft 32 connects and transmits the follower bevel teeth 31 and the rotating screw 24. This allows the four sets of rotating screws 24 to rotate synchronously at the diagonal of the mounting frame 22. Combined with the guiding and limiting effect of the limiting slide groove 34 on the connecting block 26, the movable sleeve 25 fitted on the surface of the rotating screw 24 will not rotate axially, but can only move horizontally inside the transmission frame 23. Subsequently, under the connecting transmission effect of the connecting block 26, the sliding frame 27 can be driven to move horizontally relative to the outside of the mounting frame 22 at the diagonal. This, in turn, drives the abutment plate 29 to move horizontally relative to the inside of the packaging bag opening until the abutment plate 29 adheres to the inner wall of the packaging bag opening, continuously abutting the packaging bag opening and completely opening and fixing it, facilitating the rapid dumping of materials inside the packaging bag.

[0031] It is worth noting that, see Figures 1 to 4 The fixed base 1 has support plates 11 vertically fixed on both sides of the top. The outer wall of the placement frame 13 is rotatably installed inside the support plate 11 through bearings. The top side of the support plate 11 is fixedly installed with a drive motor 12, and the drive shaft of the drive motor 12 is connected to the outer wall of the placement frame 13. The top side of the placement frame 13 has a discharge groove 14. The top outer wall of the placement frame 13 is fixedly installed with a guide plate 15. The top two sides of the guide plate 15 are fixedly installed with baffle plates 16. The guide plate 15 and the baffle plates 16 are both located outside the discharge groove 14.

[0032] After the opening of the raw material packaging bag is fixed and opened, the drive motor 12 is turned on by the external controller, which drives the placement frame 13 and the raw material packaging bag placed vertically inside to rotate synchronously. After the packaging bag tilts, the raw material inside can be automatically discharged from the discharge chute 14 under its own gravity. Then, with the guidance of the guide plate 15 and the baffle plate 16, the material is guided and transported to the feed port of the screw extruder, completing the automatic feeding process of the permeation masterbatch extrusion processing.
