Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a twin-screw granulator facilitating feeding. Background Technique

[0002] Twin-screw granulators are mainly used for the processing of filling, blending, modification, addition, chlorination, polypropylene and superabsorbent resins of rubber and plastics and engineering resins. A twin-screw granulator is an efficient granulation device, mainly used for compressing powdery raw materials into granular form for easy storage, transportation and use. It adopts a twin-screw structure, has a large production capacity and good granulation effect, and is widely used in industries such as chemical engineering, pharmaceuticals, and food. The working principle of a twin-screw granulator is to input raw materials into the machine through the feed inlet, and through the extrusion, mixing, shearing, etc. of the twin screws, the raw materials are formed into uniform particles in a short time. Its main components include a feeding system, a pressure system, an extrusion system, a cutting system, etc. In a twin-screw granulator, the raw materials enter the machine through the feeding system. First, under the action of the twin screws, the raw materials are extruded, mixed and sheared, gradually forming particles. Then, the raw materials are extruded out of the machine through the extrusion system to form a continuous particle stream, and finally are cut into the required length by the cutting system to complete the granulation process.

[0003] For example, Chinese Patent with publication number CN218139188U discloses a twin-screw granulator facilitating cleaning, belonging to the technical field of granulators, including a support table, a granulator body arranged above the support table, and a feed hopper arranged above the support table body; a cross-shaped support plate is fixedly connected to the top end of the feed hopper, a rotating motor is fixedly connected to the top end of the support plate, the output shaft of the rotating motor penetrates into the inner cavity of the feed hopper and is connected with a connecting rod, a plurality of crushing knives are fixedly connected to the rod body of the connecting rod, a scraper adapted to the inner diameter of the feed hopper is fixedly connected to the bottom end of the crushing knife and on the rod body of the connecting rod, and a filter plate is rotatably connected to the rod body of the connecting rod below the scraper. This twin-screw granulator facilitating cleaning is not only convenient for filling the granulator body and cleaning the inner cavity of the granulator body, but also convenient for extruding raw materials to form plastic strips, with simple operation;

[0004] The technical solution recorded in this scheme realizes cleaning by allowing a substance with friction to enter the interior of the granulator body through the feed hopper and driving the substance with friction to rotate by the twin screws in the inner cavity of the granulator body, generating friction on the inner cavity of the granulator body and the screws. However, in the actual use process of this scheme, the height of the feed hopper is relatively high, resulting in inconvenience for users to feed raw materials during the use of the twin-screw granulator, affecting user experience. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a twin-screw granulator that is convenient for feeding, so as to solve the problems raised in the above-mentioned background technology.

[0006] In view of the above problems, the technical solution proposed by the present utility model is:

The bottom surface of the square frame is connected with the installation groove. And a lifting plate is slidably provided inside the square frame. A rotating mechanism is provided on the outer side of one side of the lifting plate. A storage mechanism is provided on the back surface of the rotating mechanism. The storage mechanism includes a storage cylinder. A screw feeder is provided at the bottom end of the storage cylinder. The bottom end of the screw feeder is communicated with a discharge pipe on the side far from the storage cylinder.

[0008] Further, a lead screw is rotatably connected inside the square frame. A slide bar is connected on one side of the lead screw inside the square frame. One end of the lead screw penetrates through the lifting plate and extends to the outside, and is threadedly connected with the lifting plate. One end of the slide bar penetrates through the lifting plate and extends to the outside, and is slidably connected with the lifting plate. A first motor is provided on the upper end surface of the square frame. The output end of the first motor is drivingly connected with the lead screw. The beneficial effect of adopting the above further scheme is that by setting the first motor, when the first motor is started, it is convenient to drive the lead screw to rotate. When the lead screw rotates, it is convenient to make the lifting plate threadedly connected to its outside linearly move under the sliding action of the slide bar.

[0009] Further, the rotating mechanism includes a connecting seat. One side of the outer wall of the connecting seat is connected with the lifting plate. And a rotating block is rotatably connected inside the connecting seat. A second motor is provided on the upper end surface of the connecting seat. The output end of the second motor is drivingly connected with the rotating block.

[0010] The beneficial effect of adopting the above further scheme is that since the lifting plate is connected with the connecting seat, when the lifting plate moves up and down, it is convenient to drive the connecting seat to move up and down. By setting the second motor, when the second motor is started, it is convenient to drive the rotating block to rotate.

[0011] Further, a limiting ring is sleeved outside the storage cylinder. The inner wall of the limiting ring is connected with the outer wall of the storage cylinder. And one side of the outer wall of the limiting ring is connected with the rotating block. A cylinder cover is provided on the upper end surface of the storage cylinder.

[0012] The beneficial effects of adopting the above further scheme are as follows. Since the outer wall of the limit ring is connected to the rotating block, and the inner wall of the limit block is connected to the material storage cylinder, when the rotating block rotates, it is convenient to adjust the angles of the limit ring and the material storage cylinder. By setting the cylinder cover, it can prevent external impurities or foreign objects from entering the interior of the material storage cylinder, and at the same time avoid the contamination of the materials in the material storage cylinder.

[0013] Further, a feed pipe is communicated with the upper end surface of the screw feeder. One end of the feed pipe far away from the screw feeder penetrates through the material storage cylinder. The feed pipe and the discharge pipe are arranged diagonally. The discharge pipe and the through hole are located on the same axis line, and the outer diameter of the discharge pipe is the same as the inner diameter of the through hole.

[0014] The beneficial effects of adopting the above further scheme are as follows.

The length of the square groove is greater than the diameter of the limit ring.

[0016] The beneficial effects of adopting the above further scheme are as follows. When it is necessary to add materials to the interior of the material storage cylinder, when the lifting plate moves downward under the combined action of the lead screw and the slide rod, the bottom ends of the lifting plate and the connection seat respectively enter the mounting groove and the connection groove. The length of the mounting groove is greater than the length of the lifting plate. At this time, the angle of the rotating block has been adjusted from vertical to horizontal, so that the limit ring connected to the rotating block in the connection seat and the material storage cylinder enter the square groove. Further, a pair of U-shaped frames are connected to the upper end surface of the support table. Both of the pair of U-shaped frames are arranged at the bottom end of the twin-screw granulator body, and the inner walls of both of the pair of U-shaped frames are connected to the outer wall of the twin-screw granulator body.

[0017] The beneficial effects of adopting the above further solution are as follows. By setting up the U-shaped frame, the ground of the U-shaped frame is connected to the top surface of the support platform, and the inner wall of the U-shaped frame is connected to the outer wall of the twin-screw granulation body, thereby realizing the stability of the twin-screw granulator body during operation. The twin-screw granulator body consists of multiple parts such as gear transmission, feed inlet, twin screws, and extrusion head. The raw materials enter the screw cavity of the twin-screw granulator body through the feed inlet. While the twin screws are rotating, they push the raw materials forward, and the raw materials gradually become dense through continuous extrusion. Under the action of the twin screws, the raw materials start to form particles and are pushed forward to the extrusion head. Compared with the prior art, the beneficial effects of the present utility model are as follows: for this twin-screw granulator facilitating feeding, when the first motor operates, it is convenient to drive the screw rod to rotate. When the screw rod rotates, it is convenient to make the lifting plate threadedly connected to its outside realize the lifting operation under the sliding action with the sliding rod. When the lifting plate moves downward on the screw rod and the sliding rod, it is convenient for the discharge pipe of the screw feeder arranged at the bottom of the storage barrel to insert into the inside of the feed hopper through the through hole. By starting the screw feeder, the materials inside the storage barrel are discharged through the discharge pipe, and the materials enter the inside of the twin-screw feeder through the feed hopper. When there is less material inside the storage barrel and feeding is required, when the lifting plate moves upward on the screw rod and the sliding rod, the discharge pipe is completely separated from the through hole. Then, by starting the second motor, it is convenient to drive the rotating block to rotate, realize the rotation of the limiting ring and the storage barrel, and adjust the limiting ring and the storage barrel from the vertical state to the horizontal state. Then, when the lifting plate moves downward on the screw rod and the sliding rod, the limiting ring and the storage barrel connected to the rotating block in the connecting seat enter the square groove, so as to facilitate the user to open the barrel cover to add materials to the inside of the storage barrel, thereby facilitating subsequent feeding into the feed hopper.
