Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and in particular to a granulator with a slag removal lock. Background Technology

[0002] A granulator is a molding machine that can shape materials into specific shapes. The flow of materials in and out has a crucial impact on the molding process. In existing granulator conveyor systems, the conveyor stops operating after all material has entered the granulator. Before stopping the conveyor, all material in the hopper and on the conveyor belt must be completely emptied to prevent residual material from drying and entering the granulator again upon restarting, causing mold blockage. After stopping feeding, the granulator continues to run until the material in the hopper is completely processed. Then, the granulation chamber door is opened to empty the material and the door is closed. Next, fine sawdust or powder mixed with machine oil is added to the hopper to remove material from the mold and prevent it from drying and clogging.

[0003] In the process of frequent material flow operations, existing technology is difficult to flexibly control the opening and closing of the hopper, which can easily lead to incorrect judgment and control of the dynamic flow and interception of materials. This not only affects the granulation and shaping of materials, but may also cause blockages inside the granulator, making it impossible to realize the flow of materials in the complex structure of the granulator. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of inconvenient material discharge in existing granulators, and to propose a granulator with a slag-cleaning lock.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A granulator with a slag removal lock includes a machine body, on which four material hoppers are connected in sequence, and dust covers are fixedly installed on the material hoppers. The material hoppers have discharge ports located inside the dust covers, and the material hoppers are provided with fasteners for controlling the opening and closing of the discharge ports.

[0007] Preferably, the four material hoppers are arranged in a stepped manner.

[0008] Preferably, two adjacent material hoppers are connected to the discharge port through a dust cover.

[0009] Preferably, the fastener includes a steering support and a limiting fixing seat integrally connected to the outer wall of the material hopper. A damping shaft is rotatably installed in the steering support. A reinforcing rib is integrally connected to the damping shaft. A sealing arc plate corresponding to the discharge port is welded to the reinforcing rib. An outer sleeve is integrally connected to the outer wall of the sealing arc plate. A locking fixture corresponding to the limiting fixing seat is threadedly installed in the outer sleeve.

[0010] The fastener also includes a limiting baffle integrally set in the discharge port. The sealing arc plate has a central cavity and a piston elongated cavity that are connected. The sealing arc plate is provided with an elastic telescopic device that extends movably into the central cavity and corresponds to the limiting baffle. A pressure plate is integrally connected to the elastic telescopic device. A driven piston is slidably fitted in the piston elongated cavity. The driven piston is fixedly connected to a rubber ring corresponding to the side wall of the discharge port.

[0011] Preferably, the locking fixture includes a threaded post that is threadedly connected to the lower end opening of the outer sleeve. A hollow tube is integrally connected to the threaded post. A strong spring is welded inside the hollow tube. A C-shaped lifting frame that is slidably fitted into the hollow tube is fixedly installed on the strong spring. A pointed plug is fixedly connected to the C-shaped lifting frame. A countersunk hole corresponding to the pointed plug is opened at the bottom end of the limiting fixing seat.

[0012] Preferably, the pressure plate is slidably fitted into the central cavity.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-7 A granulator with a slag removal lock includes a body 1, on which four material hoppers 2 are connected in sequence, and dust covers 3 are fixedly installed on the material hoppers 2. The material hoppers 2 have discharge ports 4 located inside the dust covers 3. The material can be directionally flowed by opening and closing the discharge ports 4.

[0026] The material hopper 2 is equipped with a fastener 5 for controlling the opening and closing of the discharge port 4. Please refer to the instruction manual for details. Figure 4 - Appendix Figure 7 :

[0027] On one hand, the fastener 5 includes a steering support 51 and a limiting fixing seat 52 integrally connected to the outer wall of the material hopper 2. The steering support 51 is located on one side of the discharge port 4, and the limiting fixing seat 52 is located above the discharge port 4. A damping shaft 53 is rotatably installed in the steering support 51, which can be driven manually or by electrical equipment. A damping bearing for rotatably installing the damping shaft 53 is provided in the steering support 51. A reinforcing rib 54 is integrally connected to the damping shaft 53. A sealing arc plate 55 corresponding to the discharge port 4 is welded to the reinforcing rib 54. An outer sleeve 56 is integrally connected to the outer wall of the sealing arc plate 55. A locking fixture 57 corresponding to the limiting fixing seat 52 is threaded in the outer sleeve 56. The discharge port 4 is set as a double-layer structure. The discharge port 4 is sealed by snapping the sealing arc plate 55 into the discharge port 4.

[0028] To further explain, the locking fixture 57 includes a threaded post 571 that is threadedly connected to the lower end of the outer sleeve 56. A hollow tube 572 is integrally connected to the threaded post 571. A strong spring 573 is welded inside the hollow tube 572. A C-shaped lifting frame 574, which is slidably fitted into the hollow tube 572, is fixedly installed on the strong spring 573. A pointed plug 575 is fixedly connected to the C-shaped lifting frame 574. A countersunk hole 58 corresponding to the pointed plug 575 is opened at the bottom of the limiting fixing seat 52. By threading the locking fixture 57 into the outer sleeve 56, it is helpful to replace the pointed plug 575 after long-term use, so as to ensure the limiting and locking effect on the sealing arc plate 55.

[0029] On the other hand, the fastener 5 also includes a limiting baffle 59 integrally set in the discharge port 4. The sealing arc plate 55 has a central cavity 510 and a piston elongated cavity 511 that are connected. The sealing arc plate 55 is provided with an elastic telescopic device 512 that extends movably into the central cavity 510 and corresponds to the limiting baffle 59. The elastic telescopic device 512 adopts a T-shaped rod with a reset spring. When the sealing arc plate 55 is fastened in the discharge port 4, the elastic telescopic device 512 is squeezed by the limiting baffle 59. The elastic telescopic device 512 is integrally connected with a pressure plate 513. The driven piston 514 is slidably fitted in the piston elongated cavity 511. The driven piston 514 is fixedly connected with a rubber ring 515 corresponding to the side wall of the discharge port 4. The pressure plate 513 applies pressure to the liquid or gas in the central cavity 510, so that the driven piston 514 drives the rubber ring 515 to extend outward until the rubber ring 515 is sealed and connected to the double-layered discharge port 4.

[0030] Please refer to the instruction manual for details. Figure 1 With appendix Figure 2 The four material hoppers 2 are arranged in a stepped manner to allow the material to flow sequentially in the four material hoppers 2.

[0031] Two adjacent material hoppers 2 are connected to the discharge port 4 through a dust cover 3.

[0032] The pressure plate 513 is slidably fitted in the central cavity 510. A sealing ring is fitted on the outer edge of the pressure plate 513 to ensure that the liquid or gas in the central cavity 510 is pressurized and driven.

[0033] It should be noted that the specific model and specifications of the body 1 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0034] The functional principle of this utility model can be explained through the following operation methods:

[0035] When it is necessary to seal the discharge port 4, the damping shaft 53 is rotated in the steering support 51, and the sealing arc plate 55 is deflected to the corresponding discharge port 4 through the reinforcing rib 54.

[0036] The elastic expansion joint 512 abuts against the limiting baffle 59, causing the pressure plate 513 to pressurize the liquid in the central cavity 510, and the driven piston 514 drives the rubber ring 515 to extend, so that the rubber ring 515 abuts against the inner wall of the discharge port 4.

[0037] Under the elastic support of the strong spring 573, the U-shaped lifting frame 574 supports the pointed plug 575 to extend upward until the pointed plug 575 is snapped into place with the countersunk hole 58.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
