Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device for processing plastic products. Background Technology

[0002] Plastic products are a general term for daily necessities and industrial products made primarily from plastic. They include all products manufactured using processes such as injection molding and thermoforming. When processing plastic products, a feeding device is required to supply the raw materials.

[0003] The patent application with publication number CN219448273U, publication date August 1, 2023, entitled "A Feeding Device for Plastic Product Processing," solves the technical problems of current processing equipment that cannot be used due to the lack of an adjustment mechanism for the conveying pipe, resulting in poor feeding efficiency and excessive material feeding leading to blockage at the feeding hopper. The new device includes a base with two support blocks fixedly installed on one side of its top. Each support block has a rotating block rotatably connected to its top. A conveying pipe is installed on a fixed rod at the top of each rotating block, and a spiral conveying roller is rotatably connected inside the conveying pipe. An adjustment component is provided on the other side of the base's top. This invention enables feeding into the inner cavity of processing equipment that is too high or too low, improving feeding efficiency and preventing blockage at the feeding hopper due to excessive material.

[0004] Existing feeding devices for plastic product processing, while having the advantage of being able to feed materials into the inner cavity of processing equipment that is too high or too low, thus improving the feeding effect, have been found to have drawbacks in use. Some processing equipment has multiple feed inlets, and when the feed position needs to be adjusted, the entire feeding device needs to be moved, making it impossible to directly adjust the opening direction of the discharge pipe of the feeding device, which is inconvenient to use. Therefore, we have proposed a feeding device for plastic product processing to solve the problems mentioned above. Utility Model Content

A feed hopper is connected to the upper part of the cylinder near the motor. The cylinder and the rotating cylinder are rotatably connected by a limiting ring.

[0010] The rotating cylinder has a slot on the outer side of the limiting ring, and a locking block is fixedly connected to the inner side of the slot corresponding to the limiting ring.

[0016] Preferably, the guide rod is rectangular columnar, and the external dimensions of the guide rod match the internal dimensions of the guide rod groove.

[0017] 3. Beneficial effects:

[0018] Compared with the prior art, the feeding device for processing plastic products according to the technical solution provided by this utility model has the following specific details:

[0019] (1) When using the feeding device, the material enters the inside of the cylinder through the feeding hopper. At the same time, the motor drives the screw to rotate, and the screw drives the material to flow in the direction of the rotating cylinder. Then, it is discharged into the processing equipment through the discharge pipe. When it is necessary to adjust the opening direction of the discharge pipe as needed, the rotating cylinder drives the discharge pipe to rotate as well. The angle of the discharge pipe is locked by the locking mechanism to prevent the discharge pipe from shaking easily. Thus, the opening direction of the discharge pipe can be adjusted as needed to add the material to the required position and avoid the need to adjust the entire feeding device.

[0020] (2) When assembling the cylinder and the rotating cylinder, the cylinder and the end of the rotating cylinder are tightly attached. Then, two semi-circular rings are placed on the outside of the cylinder and the rotating cylinder to form a complete limiting ring. At the same time, the limiting ring drives the locking block to insert into the inside of the locking groove, so that the limiting ring and the rotating cylinder are fixedly connected. At the same time, the limiting ring drives the ring block to insert into the ring groove, so that the ring block can rotate in the ring groove, so that the limiting ring and the cylinder are rotatably connected. Thus, the cylinder and the rotating cylinder form a rotatable connection. When rotating, the rolling friction between the ball and the ring groove replaces the sliding friction between the ring block and the ring groove, effectively reducing the friction force on the rotating cylinder when it rotates, so that the rotating cylinder can rotate and adjust the opening direction of the discharge pipe.

[0021] (3) When the rotating cylinder needs to be rotated, the guide rod drives the locking rod to overcome the spring force and move out of the lock groove. After the adjustment is completed, the guide rod is released, and the locking rod is pressed against the limit ring by the spring. The rotating cylinder is rotated so that the locking rod is aligned with the lock groove. When the lock groove and the locking rod are aligned, the spring pushes the locking rod to insert into the lock groove, which can lock the rotating cylinder and prevent the rotating cylinder from rotating automatically.

[0031] Please see Figures 1 to 4A feeding device for processing plastic products includes a base 1, a cylindrical body 2 on top of the base 1, and the tilt angle of the cylindrical body 2 is adjustable by an adjustment mechanism.

[0032] One end of the cylinder 2 is connected to a rotating cylinder 5. The cylinder 2 and the rotating cylinder 5 are rotatably connected by a screw rod 6. A motor 7 is installed at the end of the cylinder 2 away from the rotating cylinder 5. The shaft end of the motor 7 is fixedly connected to the screw rod 6. A feed hopper 8 is connected to the top of the cylinder 2 near the motor 7. The cylinder 2 and the rotating cylinder 5 are rotatably connected by a limiting ring 9.

[0033] The rotating cylinder 5 has a slot 10 on the outer side of the limiting ring 9, and a locking block 11 is fixedly connected to the inner side of the limiting ring 9 corresponding to the slot 10. The cylinder 2 has an annular groove 12 on the annular side of the limiting ring 9, and an annular block 13 is fixedly connected to the inner side of the limiting ring 9 corresponding to the annular groove 12. The bottom of the rotating cylinder 5 is connected to the discharge pipe 16, and the rotating cylinder 5 is locked by a locking mechanism to lock its deflection angle.

[0034] When using the feeding device, the material enters the interior of the cylinder 2 through the feed hopper 8. At the same time, the motor 7 drives the screw rod 6 to rotate, which in turn drives the material to flow towards the rotating cylinder 5. The material is then discharged into the processing equipment through the discharge pipe 16. When it is necessary to adjust the opening orientation of the discharge pipe 16 as needed, the rotating cylinder 5 rotates, causing the discharge pipe 16 to rotate as well. The angle of the discharge pipe 16 is locked by a locking mechanism to prevent the discharge pipe 16 from easily shaking. This allows the opening orientation of the discharge pipe 16 to be adjusted as needed to add material to the required position without requiring the entire feeding device to be adjusted.

[0035] Please see Figures 1 to 4 The adjustment mechanism includes a support rod 3. The support rod 3 is fixedly connected to the bottom of one side of the cylinder 2. The bottom end of the support rod 3 is rotatably connected to the base 1. A hydraulic rod 4 is rotatably connected to the lower part of the cylinder 2 away from the support rod 3. The end of the hydraulic rod 4 away from the cylinder 2 is rotatably connected to the base 1. When it is necessary to adjust the height of the discharge pipe 16 according to the height of the equipment inlet, the hydraulic rod 4 drives the cylinder 2 to rotate around the support rod 3 as the fulcrum through extension and retraction, thereby adjusting the height of the discharge pipe 16.

[0036] Please see Figures 1 to 4The limiting ring 9 consists of two semicircular rings, which are fixedly connected by bolts. The locking block 11 is cylindrical, and its outer diameter matches the inner diameter of the locking groove 10. The annular block 13 is located inside the annular groove 12 and has symmetrically opened ball grooves 14 on its outer side. Balls 15 are provided on the inner side of the ball grooves 14. The annular block 13 contacts the inner wall of the annular groove 12 through the balls 15. When assembling the cylinder 2 and the rotating cylinder 5, the ends of the cylinder 2 and the rotating cylinder 5 are made to fit tightly. Then, the two semicircular rings are fitted onto the outer sides of the cylinder 2 and the rotating cylinder 5 to form a complete limiting ring 9. At the same time, the limiting ring 9... The locking block 11 is inserted into the slot 10, which fixes the limiting ring 9 to the rotating cylinder 5. At the same time, the limiting ring 9 drives the annular block 13 to be inserted into the annular groove 12, so that the annular block 13 can rotate in the annular groove 12. This makes the limiting ring 9 rotatably connected to the cylinder 2, and thus the cylinder 2 and the rotating cylinder 5 are rotatably connected. During rotation, the rolling friction between the ball 15 and the annular groove 12 replaces the sliding friction between the annular block 13 and the annular groove 12, which effectively reduces the friction force on the rotating cylinder 5 during rotation, so that the rotating cylinder 5 can rotate and adjust the opening orientation of the discharge pipe 16.

[0037] Please see Figures 1 to 4 The locking mechanism includes a fixed frame 17. The fixed frame 17 is fixedly connected to the top of the cylinder 2 near the limiting ring 9. A guide rod groove 18 passes through the inner side of the fixed frame 17. A guide rod 19 passes through the inside of the guide rod groove 18. A sliding frame 20 is fixedly connected to one end of the guide rod 19 near the limiting ring 9. A spring 21 is sleeved on the guide rod 19 between the sliding frame 20 and the fixed frame 17. Locking grooves 22 are distributed in a ring at equal intervals on one side of the limiting ring 9 near the sliding frame 20. A locking rod 23 is fixedly connected to one end of the sliding frame 20 corresponding to the locking groove 22. The guide rod 19 is a rectangular column. The guide rod 19 is positioned such that its external dimensions match the internal dimensions of the guide rod groove 18. When the rotating cylinder 5 needs to rotate, the guide rod 19 drives the locking rod 23 to overcome the elastic force of the spring 21 and move out of the locking groove 22. After adjustment, the guide rod 19 is released, and the locking rod 23 abuts against the limiting ring 9 through the spring 21. The rotating cylinder 5 is rotated so that the locking rod 23 is aligned with the locking groove 22. When the locking groove 22 and the locking rod 23 are aligned, the spring 21 pushes the locking rod 23 into the locking groove 22, which locks the rotating cylinder 5 and prevents the rotating cylinder 5 from rotating automatically.

[0038] Working principle: When using this feeding device for processing plastic products, such as Figures 1 to 4As shown, firstly, when using the feeding device, the material enters the interior of the cylinder 2 through the feed hopper 8. At the same time, the motor 7 drives the screw rod 6 to rotate, and the screw rod 6 drives the material to flow towards the rotating cylinder 5. Then, it is discharged into the processing equipment through the discharge pipe 16. When it is necessary to adjust the opening orientation of the discharge pipe 16 as needed, the rotating cylinder 5 rotates to drive the discharge pipe 16 to rotate as well. The angle of the discharge pipe 16 is locked by the locking mechanism to prevent the discharge pipe 16 from easily shaking. Thus, the opening orientation of the discharge pipe 16 can be adjusted as needed to add the material to the required position, avoiding the need to adjust the entire feeding device. When it is necessary to adjust the height of the discharge pipe 16 according to the height of the equipment inlet, the hydraulic rod 4 extends and retracts to drive the cylinder 2 to rotate around the support rod 3 as the fulcrum, thus adjusting the height of the discharge pipe 16.

[0039] During the assembly of the cylinder 2 and the rotating cylinder 5, the ends of the cylinder 2 and the rotating cylinder 5 are brought into close contact. Then, two semi-circular rings are fitted around the outside of the cylinder 2 and the rotating cylinder 5 to form a complete limiting ring 9. At the same time, the limiting ring 9 drives the locking block 11 to insert into the inside of the locking groove 10, thus fixing the limiting ring 9 to the rotating cylinder 5. Simultaneously, the limiting ring 9 drives the annular block 13 to insert into the annular groove 12, allowing the annular block 13 to rotate within the annular groove 12, thus rotatably connecting the limiting ring 9 to the cylinder 2. This, in turn, establishes a rotatable connection between the cylinder 2 and the rotating cylinder 5. Furthermore, during rotation, the rolling friction between the ball bearing 15 and the annular groove 12 replaces the friction between the annular block 13 and the annular groove 12. The sliding friction between them effectively reduces the friction force experienced by the rotating cylinder 5 when it rotates, so that the rotating cylinder 5 can rotate and adjust the opening orientation of the discharge pipe 16. When the rotating cylinder 5 needs to rotate, the guide rod 19 drives the locking rod 23 to overcome the elastic force of the spring 21 and move out of the locking groove 22. After the adjustment is completed, the guide rod 19 is released, and the locking rod 23 abuts against the limiting ring 9 through the spring 21. The rotating cylinder 5 is rotated so that the locking rod 23 is aligned with the locking groove 22. When the locking groove 22 and the locking rod 23 are aligned, the spring 21 pushes the locking rod 23 into the locking groove 22, which can lock the rotating cylinder 5 and prevent the rotating cylinder 5 from rotating automatically.
