Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding mechanism for a casting machine. Background Technology
[0002] A casting machine is a mechanical device used for forming cast films from rubber and plastic materials. It is mainly used in fields such as casting film production, developing casting material formulations, and researching the performance of casting materials. For example, it transports materials to the casting machine and retrieves the cast film products. Casting machines have a wide range of applications and can be used to produce various products from PE films, especially disposable products such as diapers, sanitary napkins, and medical protective clothing. The existing feeding mechanism for casting machines does not have the function of mixing and screening raw materials during the feeding process. As a result, during the feeding process, the raw materials inside the barrel will clump together. The clumped raw materials will not only damage the casting machine during the feeding process, but may also cause a large number of waste and defective products. Utility Model Content
[0003] To address the aforementioned problems, this invention proposes a feeding mechanism for a casting machine to more accurately resolve these issues.
[0004] This utility model is achieved through the following technical solution: This utility model proposes a feeding mechanism for a casting machine, including a barrel, a motor disposed at the top of the barrel, and a discharge column disposed at the bottom of the barrel. An annular column is disposed above the interior of the barrel. A screen is disposed inside the barrel and on the outer surface of the annular column. A crushing roller for crushing particles on the screen is rotatably connected to the annular column via a rotating assembly. One end of the crushing roller passes through the annular column and is connected to a first conical tooth. The output end of the motor passes through the top of the barrel and is connected to a rotating rod. A second conical tooth that mates with the first conical tooth is disposed on the outer surface of the rotating rod and inside the annular column. A feeding track is disposed on the lower end face of the rotating rod and inside the discharge column. A raw material injection pipe is disposed at the top of the barrel.
[0005] Furthermore, the present invention includes a pressure roller, a connecting rod disposed at one end of the pressure roller, and a first conical tooth disposed on one side of the connecting rod.
[0006] Furthermore, the rotating assembly includes mounting holes on both sides of the barrel, bearings disposed within the mounting holes, and a first seal disposed between the bearings and the connecting rod.
[0007] Furthermore, the screening mesh includes a first annular frame connected to the inner wall of the material cylinder, an annular mesh is provided on the inner side of the first annular frame, a second annular frame is provided on the inner side of the annular mesh, and a second sealing element is provided between the second annular frame and the rotating rod.
[0008] Furthermore, the present invention provides that the material cylinder has connecting material cylinders on both sides and a through hole is provided outside the first annular frame. Mounting plates are provided on both sides of the material cylinder, and vibrating elements are provided on the mounting plates. The output end of the vibrating element passes through the through hole and contacts the outer surface of the first annular frame.
[0009] Furthermore, in this invention, support frames are fixedly installed on the lower sides of both sides of the material cylinder, and fixing plates are provided on the outer sides of the two support frames.
[0010] The beneficial effects of this utility model are: The electric motor drives the rotating rod to rotate, which in turn drives the feeding track to rotate, thus feeding the raw materials. At the same time, as the rotating rod rotates, it also drives the second conical tooth to rotate. The second conical tooth meshes with the first conical tooth, and simultaneously causes the crushing roller to crush the agglomerated raw materials blocked by the screening screen. This not only avoids the waste of raw materials but also ensures the maximum utilization of raw materials. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0014] Example refer to Figure 1-6 A feeding mechanism for a casting machine includes a cylinder 1, a motor 11 disposed at the top of the cylinder 1, and a discharge column 12 disposed at the bottom of the cylinder 1. An annular column 13 is disposed above the interior of the cylinder 1. A screen 2 is disposed inside the cylinder 1 and on the outer surface of the annular column 13. A rolling roller 4 for crushing particles on the screen 2 is rotatably connected to the annular column 13 via a rotating assembly 3. One end of the rolling roller 4 passes through the annular column 13 and is connected to a first conical tooth 41. The output end of the motor 11 passes through the top of the cylinder 1 and is connected to a rotating rod 14. A second conical tooth 15 that cooperates with the first conical tooth 41 is disposed on the outer surface of the rotating rod 14 and inside the annular column 13. A feeding track 16 is disposed on the lower end face of the rotating rod 14 and inside the discharge column 12. A raw material injection pipe 17 is disposed at the top of the cylinder 1. The motor 11 drives the rotating rod 14 to rotate, which in turn drives the feeding track 16 to rotate, thus completing the feeding of raw materials. At the same time, during the rotation of the rotating rod 14, the second conical tooth 15 will rotate, and the second conical tooth 15 will mesh with the first conical tooth 41, which will simultaneously cause the crushing roller 4 to crush the agglomerated raw materials blocked on the screening screen 2. This not only avoids the waste of raw materials, but also ensures the maximum utilization of raw materials. In this embodiment, the screen 2 is designed to block agglomerated raw materials, thereby preventing the casting machine from using agglomerated raw materials. In this embodiment, preferably, four rolling rollers 4 are provided.
[0015] like Figure 4 and Figure 5 As shown, the crushing roller 4 includes a pressure roller 42, a connecting rod 43 disposed at one end of the pressure roller 42, and a first conical tooth 41 disposed on one side of the connecting rod 43; the first conical tooth 41 will mesh with the second conical tooth 15, and cause the connecting rod 43 and the pressure roller 42 to rotate, and complete the crushing and crushing of the agglomerated raw materials.
[0016] like Figure 4 and Figure 5 As shown, the rotating assembly 3 includes mounting holes 31 on both sides of the barrel 1, a bearing 32 disposed in the mounting holes 31, and a first sealing member 33 disposed between the bearing 32 and the connecting rod 43; The bearing 32 provides a basis for the rotation of the connecting rod 43, and the first seal 33 can effectively prevent raw materials from entering the bearing 32 and the annular column 13.
[0017] like Figure 2 and Figure 3 As shown, the screening screen 2 includes a first annular frame 21 connected to the inner wall of the material cylinder 1, an annular mesh 22 is provided on the inner side of the first annular frame 21, a second annular frame 23 is provided on the inner side of the annular mesh 22, and a second sealing element 24 is provided between the second annular frame 23 and the rotating rod 14. The ring mesh 22 can block the agglomerated raw materials, while the second seal 24 can prevent the raw materials from entering the rotating rod 14.
[0018] like Figure 6 As shown, the material cylinder 1 has connecting material cylinders 1 on both sides, and a through hole 18 is provided on the outside of the first annular frame 21. Mounting plates 5 are provided on both sides of the material cylinder 1, and a vibrating element 51 is provided on the mounting plate 5. The output end of the vibrating element 51 passes through the through hole 18 and contacts the outer surface of the first annular frame 21. The vibrating element 51 can provide vibration force to the first ring frame 21 and enable the ring mesh 22 to complete the vibration screening of raw materials. The through hole 18 can facilitate the contact between the vibrating element 51 and the first ring frame 21, ensuring that the vibrating element 51 vibrates the first ring frame 21. In this embodiment, the vibrating element 51 can adopt an existing vibration structure, such as a pneumatic vibrating element 51, etc.
[0019] like Figure 1As shown, support frames 6 are fixedly installed on the lower sides of the material cylinder 1, and fixing plates 61 are provided on the outer sides of the two support frames 6. The mounting plate 61 facilitates the installation of the equipment by staff and ensures its proper use.
[0020] Working principle: First, the operator injects the raw material to be used into the material cylinder 1 through the raw material injection pipe 17. During the raw material injection process, the vibrating component 51 applies vibration force to the screening screen 2, causing the raw material to pass through the screening screen 2. As the raw material flows downward, the motor 11 synchronously drives the rotating rod 14 to rotate. The rotating rod 14 first drives the feeding track 16 to rotate, causing the raw material inside the material cylinder 1 to move downward through the feeding track 16, thus completing the feeding work of the casting machine. In addition, during the rotation of the rotating rod 14, the second conical tooth 15 is synchronously driven to rotate. The second conical tooth 15 meshes with the first conical tooth 41, and simultaneously causes the crushing roller 4 to crush the agglomerated raw material blocked by the screening screen 2. This not only avoids the waste of raw materials but also ensures the maximum utilization of raw materials. The vibrating component 51 moves the raw material on the screening screen 2 and allows it to move to the crushing roller 4, so that the crushing roller 4 can complete the crushing work of the raw material.
[0021] It should be noted that this utility model only protects the mechanical part, and the functions implemented by the software control part are not within the scope of protection of this utility model.
[0022] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
