[0010] Furthermore, the sleeve bearing is arranged at the tail of the feeding screw, and the front of the feeding screw is provided with a pouring port, and the pouring port is formed at the front of the feeding screw through a cutting process.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection.

[0038] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the embodiments.

[0039] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in an embodiment of the present invention, a masterbatch feeder for plastic production includes a feeding system 1, the feeding system 1 includes a feeding sleeve 101, a feeding screw 103 and a feed port 104, and the distance H between the inner wall of the feeding sleeve 101 and the feeding screw 103 is 0.5mm to 1mm.

[0040] In this embodiment, the distance H between the feed screw 103 and the feed sleeve 101 is a reference quantity for the relationship between the screw and the barrel. The size of the distance H mainly depends on the following factors: the properties of the material being processed, the resistance of the machine head, the material of the feed screw 103 and the feed sleeve 101, and the screw diameter.

[0041] In this embodiment, the size of the spacing H can be selected not only according to the head resistance, but also according to the diameter of the feed screw 103; wherein, if the head resistance is greater, the spacing H is smaller, if the diameter of the feed screw 103 is larger, the spacing H is larger, and if the diameter of the feed screw 103 is smaller, the spacing H is smaller.

[0042] In this embodiment, when the distance H between the feeding screw 103 and the feeding sleeve 101 is too small, it will not only increase the resistance to feeding, but also reduce the speed and flow rate of feeding, thereby reducing the feeding capacity per unit area, resulting in reduced production efficiency. When the distance H is too large, it is easy for the masterbatch particles to stay in one place, which is also not conducive to transportation.

[0043] In this embodiment, by increasing the distance H between the feed sleeve 101 and the feed screw 103, the above-mentioned problems can be effectively reduced, and the maximum value of the distance H will not cause a large number of masterbatch particles to gather in the gap between the feed sleeve 101 and the feed screw 103, thereby ensuring the overall working efficiency.

[0044] like Figure 5 and Figure 7 As shown, the feed screw 103 includes an extrusion section 1031, a feeding section 1032 and a partition zone L. The extrusion section 1031 is arranged at the front of the feed screw 103, and the feeding section 1032 is arranged at the rear of the feed screw 103. A partition zone L is arranged between the extrusion section 1031 and the feeding section 1032. At least part of the screw area of ​​the partition zone L has no external thread, and the partition zone L is arranged in front of the feed port 104.

[0045] In this embodiment, the feed section 1032 refers to the area where the masterbatch enters (usually from the top) the feed sleeve 101. In this area, the masterbatch is transported to the feed area of ​​the extruder. Correspondingly, a portion of the feed sleeve 101 is open in this area to enable the input of plastic raw materials; the extrusion section 1031 refers to the area where the masterbatch is rotated, stirred, and finally extruded by the feed screw 103. In this area, the feed sleeve 101 completely wraps the feed screw 103; the partition area L refers to the area between the feed section 1032 and the extrusion section 1031. The masterbatch is transported from the partially open feed sleeve 101 through the partition area L to the inside of the closed feed sleeve 101.

[0046] In this embodiment, since the partition area L has no threads and the partition area L is located in front of the feed port 104, when the masterbatch particles enter the feed sleeve 101, the masterbatch particles will be gradually transported to the partition area L by the feed section 1032. At this time, since the partition area L has no threads, there is no inclined surface to form an angle with the feed port 104 on the feed sleeve 101, and the masterbatch particles will not accumulate at the angle and cause the feed screw 103 to get stuck. Then, as the masterbatch particles gradually increase in the partition area L and touch the threads of the extrusion section 1031, the masterbatch particles will be gradually transported to the pouring port 110 by the extrusion section 1031.

[0047] like Figure 3 As shown, the feeding system 1 includes a fixed flange 102, a mounting seat 105, a screw coupling 106, a motor 107, a maintenance sleeve cylinder 108, a sleeve bearing 109 and a pouring port 110. The mounting seat 105 is fixed to the inside of the housing 3 by fixing bolts, the fixed flange 102 is fixed to the front of the mounting seat 105, the feeding sleeve 101 is fixed to the middle of the fixed flange 102, the feeding screw 103 is arranged in the inside of the feeding sleeve 101, and the rear part of the feeding sleeve 101 is provided with a feeding port 104, and the feeding port 104 is formed at the rear part of the feeding sleeve 101 by a cutting process.

[0048] like Figure 3 and Figure 5 As shown, the screw coupling 106 is fixed to the rear of the feeding screw 103 by fixing bolts, the motor 107 is arranged at the rear of the screw coupling 106, the maintenance sleeve cylinder 108 is arranged outside the screw coupling 106, the sleeve bearing 109 is arranged at the tail of the feeding screw 103, and the front of the feeding screw 103 is provided with a pouring port 110, and the pouring port 110 is formed at the front of the feeding screw 103 through a cutting process.

[0049] In this embodiment, the masterbatch particles enter the feed sleeve 101 from the feed port 104, and the motor 107 is connected to the feed screw 101 through the screw coupling 106. If the motor 107 is started, it can drive the screw coupling 106 to rotate, and the rotation of the screw coupling 106 will drive the feed screw 103 to rotate.

[0050] In this embodiment, the main function of the fixing flange 102 is to fix the feed sleeve 101. During the later maintenance, the screw coupling 106 can be observed to see if it is damaged by inspecting the sleeve cylinder 108. Finally, to ensure that the feed screw 103 can rotate freely inside the feed sleeve 101, this can be achieved through the sleeve bearing 109. First, the sleeve bearing 109 is fixed to the feed screw 103, and then the sleeve bearing 109 is movably connected to the feed sleeve 101, so as to achieve the above purpose.

[0051] In this embodiment, in order to ensure that the masterbatch particles can enter the interior of the feed sleeve 101 through the feed port 104, the storage system 4 needs to be fixed to the upper part of the mounting seat 105. The discharge port 405 inside the feed system 4 will automatically align with the feed port 104 to ensure that the masterbatch particles can accurately enter the interior of the feed sleeve 101.

[0052] like Figure 8 As shown, the sleeve bearing 109 is arranged at the tail of the feeding screw 103 , and the front of the feeding screw 103 is provided with a pouring port 110 , which is formed at the front of the feeding screw 103 by a cutting process.

[0053] In this embodiment, the masterbatch particles are continuously transported forward due to the continuous rotation of the feeding screw 103. When the masterbatch particles finally reach the pouring port 110, they can leave the feeder through the pouring port 110, or they can be directly transported to subsequent production equipment.

[0054] like Figure 1 , Figure 2 and Fig. 9 As shown, in an embodiment of the present invention, a masterbatch feeder for plastic production includes an integrated touch control system 2, which is arranged inside a housing 3. The integrated touch control system 2 includes a PLC unit 201, a power output device 202, a motor driver 203, a cooling fan 204, a touch screen 205, a heat dissipation hole 206 and a cable hole 207.

[0055] like Fig. 9 As shown, the PLC unit 201 is fixed to the inside of the shell 3 by fixing bolts, the power output device 202 is fixed to the inside of the shell 3, the motor driver 203 is detachably connected to the inside of the shell 3 by fixing bolts, and the cooling fan 204 is symmetrically arranged on both sides of the shell 3 by fixing bolts.

[0056] In this embodiment, PLC refers to a programmable logic controller (PLC). Since a programmable logic controller, PLC unit 201, is used, the PLC unit 201 can be programmed and stored so that the PLC unit 201 has functions such as logic operation, sequence control, and timing.

[0057] In this embodiment, since the PLC unit 201 is programmed and stored, the PLC unit 201 has remote control. At this time, the production personnel can remotely change the production parameters according to their own needs and adjust the delivery frequency and flow rate of the masterbatch particles; and the remote alarm function can also be realized through the PLC unit 201 to prevent the production personnel from being unable to observe the stock of the masterbatch particles in the hopper 402 through the observation port 403 in time due to not being near the feeder.

[0058] like Fig. 9 As shown, the touch screen 205 is detachably connected to the outside of the shell 3 by fixing screws, the bottom of the shell 3 is provided with a heat dissipation hole 206, and the heat dissipation hole 206 passes through the bottom of the shell 3 through a hole-punching process, and the side of the shell 3 is provided with a cable hole 207, and the cable hole 207 passes through the side of the shell 3 through a hole-punching process.

[0059] In this embodiment, the cable can be passed through the cable hole 207 on the housing 3 and then connected to the power output device 202. At this time, the power output device 202 can supply power to subsequent parts such as the motor driver 203 and the cooling fan 204.

[0060] In this embodiment, production personnel can perform localized operations through the touch screen 205. At this time, the production personnel can directly set various parameters through the touch screen 205, and can also start and stop the machine through the touch screen 205. When internal parts of this embodiment fail, the fault parameters can also be retrieved through the touch screen 205 to facilitate maintenance.

[0061] In some embodiments, when the PLC unit 201, the power output device 202, the motor driver 203 and other parts work for too long, a large amount of heat will be generated inside the machine. At this time, the cooling fan 204 and the heat dissipation holes 206 can be used to increase the air flow inside the housing 3, thereby achieving a cooling effect.

[0062] like Figure 1 , Figure 2 , Fig.10 As shown, in an embodiment of the present invention, a masterbatch feeder for plastic production includes a storage system 4, which is arranged at the upper part of the outer shell 3. The storage system 4 includes a silo mounting seat 401, a hopper 402, an observation port 403, a silo cover 404 and a discharge port 405. The silo mounting seat 401 is fixedly connected to the upper part of the mounting seat 105 by fixing bolts, and the hopper 402 is fixedly connected to the upper part of the silo mounting seat 401 by welding.

[0063] Observation ports 403 are respectively provided on both sides of the hopper 402, and the observation ports 403 are fixed to the two sides of the hopper 402 by welding. The silo cover 404 is provided on the upper part of the hopper 402, and a discharge port 405 is provided at the bottom of the silo mounting seat 401. The discharge port 405 is formed at the bottom of the silo mounting seat 401 by a cutting process, and the discharge port 405 is aligned with the feed port 104.

[0064] In this embodiment, with regard to the prior art, in most cases, both sides of the hopper 402 are provided with observation ports 403. If production personnel need to check how many masterbatch particles are inside the hopper 402, they need to open the hopper cover 404 for close observation, which wastes manpower.

[0065] In this embodiment, the masterbatch particles can be poured into the hopper 402 by opening the silo cover 404 on the storage system 4. At this time, the amount of masterbatch particles in the hopper 402 can be observed through the observation port 403 to ensure that there are enough masterbatch particles in the hopper 402 to meet production needs. Because the discharge port 405 is aligned with the feed port 104, the masterbatch particles in the hopper 402 will gradually enter the feed sleeve 101 and be continuously transported forward by the feed screw 103.

[0066] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0067] Although embodiments have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations may be made to the embodiments without departing from the principles and spirit thereof, and the scope of the embodiments is defined by the appended claims and their equivalents.

[0068] The above description of the implementation mode is not restrictive, and the drawings show only one of the implementation modes, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the scope of protection.
