Description

Technical Field

[0001] The utility model relates to the field of injection molding feeding devices, in particular to an injection molding feeding assembly capable of continuously feeding materials. Background Technique

[0002] An injection molding machine, also known as an injection molding machine or an injection machine, is the main molding equipment for making various shaped plastic products from thermoplastic or thermosetting plastics using plastic molding dies. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat plastics, apply high pressure to the molten plastics, and inject them to fill the mold cavity. The injection molding machine has the ability to form dense plastic products with complex outer shapes, precise dimensions, or metal inserts in one go, and is widely used in various fields such as national defense, electromechanics, automobiles, transportation, building materials, packaging, agriculture, culture, education, health, and people's daily lives. During the operation of the injection molding machine, it is necessary for the staff to feed plastics into the injection molding machine.

[0003] In the existing injection molding machine, usually, the staff responsible for feeding materials stands at a high place and feeds thermoplastic or thermosetting plastics into the injection molding machine. Once the situation of raw materials sticking to the wall occurs, manual stirring needs to be carried out immediately, which is extremely dangerous and also increases the labor intensity of the staff.

[0004] Therefore, an injection molding feeding assembly capable of continuously feeding materials is proposed. Content of the Utility Model

[0005] In view of the above problems, the utility model provides an injection molding feeding assembly capable of continuously feeding materials to solve the problems raised in the above background technique.

[0006] The technical solution of the utility model is as follows:

[0007] An injection molding feeding assembly capable of continuously feeding materials includes a workbench, an injection cavity pipe, a feeding pipe, and a feeding hopper. The injection cavity pipe is fixed on the top surface of the workbench through a bracket. The feeding pipe is communicated with the surface of the injection cavity pipe. The feeding hopper is communicated with the top end of the feeding pipe. A support frame is fixedly connected to the side wall of the workbench. The top end of the support frame is hinged with a fixed sleeve. The top surface of the fixed sleeve is fixedly connected with a feeding pipe. One end of the feeding pipe is located at the top opening of the feeding hopper. A boss is fixedly connected to one side wall of the support frame. The top surface of the boss is fixedly connected with a second electric telescopic rod. The telescopic end of the second electric telescopic rod is fixedly connected with a rotating block through a sliding strip. The end of the rotating block away from the second electric telescopic rod is hinged with a hinge sleeve. A sliding opening for sliding connection with the sliding strip is formed in the middle of the bottom surface of the hinge sleeve. The top end of the hinge sleeve is fixedly connected with a supporting sleeve. The top surface of the supporting sleeve is fixed at the end of the feeding pipe away from the feeding hopper.

[0008] In a further technical solution, a bearing frame is fixedly connected to the inner wall of the feed hopper. A rotating shaft and a rotating rod are rotatably connected to the surface of the bearing frame. The rotating shaft and the rotating rod are relatively perpendicular. One end of the rotating shaft is fixedly connected to a first bevel gear. A second bevel gear is meshed with the outer surface of the first bevel gear. The bottom surface of the second bevel gear is fixed to the top end of the rotating rod. A scraping frame is fixedly connected to the outer surface of the rotating rod. One side surface of the scraping frame away from the rotating rod is attached to the inner wall of the feed hopper. A motor is fixedly connected to the outer surface of the feed hopper. The output end of the motor is fixedly connected to the end of the rotating shaft away from the first bevel gear.

[0009] In a further technical solution, the feed pipe includes a feed opening, a storage cavity, a contraction groove, and a baffle. The feed opening is opened in the middle of the top surface of the feed pipe. The storage cavity is located at the end of the feed pipe away from the feed hopper. A baffle is slidably connected to the opening of the feed opening. A contraction groove is opened on the top surface of the inner wall of the feed pipe. The baffle is used in cooperation with the contraction groove through a driving member.

[0010] Through the above technical solution, it is convenient to put the raw materials into the storage cavity. The baffle extends and closes at the opening of the feed opening to ensure that the raw materials will not spill due to the inclination of the feed pipe. At the same time, when discharging the materials, the baffle can be made to move away from the feed opening to facilitate the feeding of the raw materials.

[0011] In a further technical solution, the driving member includes a first electric telescopic rod. A connecting block is fixedly connected to the top surface of the end of the baffle away from the contraction groove. The housing of the first electric telescopic rod is fixed to the top surface of the feed pipe. The telescopic end of the first electric telescopic rod is fixed to the surface of the connecting block.

[0012] Through the above technical solution, when the first electric telescopic rod is conveniently contracted, the baffle can be retracted into the inner wall of the contraction groove.

[0013] In a further technical solution, a sealing opening is opened on one side of the top surface of the feed hopper. The bottom surface of the end of the feed pipe away from the feed opening is attached to the surface of the sealing opening, and the surface of the sealing opening is arc-shaped.

[0014] Through the above technical solution, it is convenient for the feed pipe to be inclined and in contact with the sealing opening.

[0015] In a further technical solution, the sliding opening is arc-shaped.

[0016] Through the above technical solution, the supporting sleeve can support the feed pipe to make an arc-shaped movement, which is convenient for tilting the feed pipe for feeding.

[0017] Compared with the prior art, the present utility model has the following beneficial effects:

[0018] 1. By contracting the second electric telescopic rod, the end of the feeding pipe away from the feeding hopper can be tilted downward. Then, the raw materials can be placed in the feeding pipe by the staff below. After that, through the extension of the second electric telescopic rod, the end of the feeding pipe with raw materials is lifted upward, causing the feeding pipe to tilt and pour the raw materials into the interior of the feeding hopper. This avoids continuous manual labor, improves the working efficiency of feeding, and is conducive to continuous feeding.

[0019] 2. Driven by the motor, the rotating shaft can rotate to engage the first bevel gear and the second bevel gear, so that the rotating rod drives the scraping rack to rotate on the inner wall of the feeding hopper, avoiding the situation of material sticking to the wall and also avoiding the safety hazards of manual work at high places.

A rotating shaft 18 and a rotating rod 20 are rotatably connected to the surface of the bearing bracket 17. The rotating shaft 18 and the rotating rod 20 are relatively perpendicular. One end of the rotating shaft 18 is fixedly connected to a first bevel gear 19. A second bevel gear 21 is meshed with the outer surface of the first bevel gear 19. The bottom surface of the second bevel gear 21 is fixed to the top end of the rotating rod 20. A scraping frame 22 is fixedly connected to the outer surface of the rotating rod 20. One side surface of the scraping frame 22 away from the rotating rod 20 is attached to the inner wall of the feed hopper 4. A motor 23 is fixedly connected to the outer surface of the feed hopper 4. The output end of the motor 23 is fixedly connected to the end of the rotating shaft 18 away from the first bevel gear 19.

[0033] Please refer to Figure 2 and Figure 3 , the feeding pipe 6 includes a feeding port 61, a receiving cavity 62, a contraction groove 63, and a baffle 64. The feeding port 61 is opened in the middle of the top surface of the feeding pipe 6. The receiving cavity 62 is located at the end of the feeding pipe 6 away from the feed hopper 4. A baffle 64 is slidably connected to the opening of the feeding port 61. A contraction groove 63 is opened on the top surface of the inner wall of the feeding pipe 6. The baffle 64 is used in cooperation with the contraction groove 63 through a driving member.

[0034] It is convenient to put the raw materials into the receiving cavity 62. Through the extension and closing of the baffle 64 at the opening of the feeding port 61, it is ensured that the raw materials will not spill due to the inclination of the feeding pipe 6. At the same time, when discharging the materials, the baffle 64 can be moved away from the feeding port 61 to facilitate the feeding of the raw materials.

[0035] Please refer to Figure 1 and Figure 2 , the driving member includes a first electric telescopic rod 9. A connecting block 8 is fixedly connected to the top surface of the end of the baffle 64 away from the contraction groove 63. The housing of the first electric telescopic rod 9 is fixed on the top surface of the feeding pipe 6. The telescopic end of the first electric telescopic rod 9 is fixed on the surface of the connecting block 8.

[0036] When it is convenient to contract the first electric telescopic rod 9, the baffle 64 can be received into the inner wall of the contraction groove 63.

[0041] During operation, first, the staff starts the motor 23 to run. The output end of the motor 23 drives the rotating shaft 18 to rotate. The first bevel gear 19 at one end of the rotating shaft 18 meshes with the second bevel gear 21, causing the rotating rod 20 to drive the scraping frame 22 to rotate on the inner wall of the feed hopper 4, preventing raw materials from sticking to the wall. Subsequently, the second electric telescopic rod 12 is driven to extend, and its telescopic end drives the rotating block 13 to move through the sliding strip. Since the rotating block 13 is hinged to the hinge sleeve 15, and the hinge sleeve 15 is slidably connected to the sliding strip through the sliding opening 16, and at the same time, the supporting sleeve 14 at the top of the hinge sleeve 15 is fixedly connected to the feeding pipe 6, one end of the feeding pipe 6 away from the feed hopper 4 is tilted downward. At this time, the first electric telescopic rod 9 is driven to contract, driving the connecting block 8 and the baffle 64 to move. The baffle 64 is retracted into the contraction groove 63, exposing the feeding port 61. The staff puts the raw materials into the storage cavity 62 from the feeding port 61. Subsequently, the first electric telescopic rod 9 extends, pushing the baffle 64 to extend and close at the opening of the feeding port 61 to ensure that the raw materials will not spill out when the feeding pipe 6 is tilted. At this time, the second electric telescopic rod 12 is extended again, and its telescopic end drives the rotating block 13 to move through the sliding strip. Since the rotating block 13 is hinged to the hinge sleeve 15, and the hinge sleeve 15 is slidably connected to the sliding strip through the sliding opening 16, and at the same time, the supporting sleeve 14 at the top of the hinge sleeve 15 is fixedly connected to the feeding pipe 6, one end of the feeding pipe 6 away from the feed hopper 4 is lifted upward, presenting a state where the feeding pipe 6 is tilted to pour in the material. The raw materials slide along the feeding pipe 6 and enter the inside of the feed hopper 4 from the sealing port 7 on one side of the top surface of the feed hopper 4. This device realizes continuous feeding, avoiding continuous manual labor and improving the working efficiency of feeding.
