Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of extrusion granulators, in particular to a double-stage extrusion granulator unit for rubber tubes. Background Art
[0002] At present, the two-stage extruder granulator has been widely used in the fields of plastics and rubber. The twin-screw extruder can add solid raw materials such as polymer pellets or flakes into the screw part through the feed port, and plasticize the polymer material into a molten state through the combined effects of heating and the extrusion force of the screw. With the continuous development and improvement of related technologies, the functions of the two-stage extruder granulator have gradually matured, but there are still deficiencies in some aspects, such as:
[0003] When processing rubber raw materials, the two-stage extrusion granulator in the prior art only completes the feeding effect based on the weight of the raw materials themselves. During the feeding process, the rubber raw materials are prone to blockage due to their irregular shapes and the large friction between them. At this time, manual unblocking is required, which brings inconvenience to actual use. Therefore, a method is needed to stir the raw materials during the feeding process to ensure continuous feeding effect. Utility Model Content
[0004] The utility model provides a double-stage extrusion granulation machine unit for a rubber tube, which has the beneficial effect of being able to stir the raw materials in the process of adding, thereby ensuring a continuous feeding effect.
[0005] A two-stage extrusion granulation unit for rubber tubes comprises a two-stage extruder main body, a feeding part is fixedly connected to the two-stage extruder main body, a connecting frame is connected to the two-stage extruder main body, a swivel seat is connected to the connecting frame, a toggle rod is fixedly connected to the swivel seat, the swivel seat can rotate around a virtual axis, and a discharge port is arranged on the front side of the two-stage extruder main body.
[0006] The feeding part is in the shape of a frustum which is wide at the top and narrow at the bottom.
[0007] It also includes a slide bar which is slidably connected to the connecting frame, and a swivel seat is rotatably connected to the slide bar.
[0008] It also includes an extension rod which is slidably connected to the toggle rod, and a compression spring is fixedly connected between the toggle rod and the extension rod. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0013] Figure 5 It is a structural schematic diagram of the toggle lever. DETAILED DESCRIPTION
[0014] like Figure 1-5 As shown:
[0015] The double-stage extruder body 101 includes a feeding part 102 fixedly connected to the double-stage extruder body 101, a connecting frame 201 connected to the double-stage extruder body 101, a swivel seat 303 connected to the connecting frame 201, a toggle rod 304 fixedly connected to the swivel seat 303, the swivel seat 303 can rotate around a virtual axis, and a discharge port is provided on the front side of the double-stage extruder body 101.
[0016] The crushed rubber raw material is put into the feeding part 102, and then the double-stage extruder main body 101 is started to form rubber particles after extrusion and granulation of the rubber raw material, and then the rubber particles are subjected to subsequent molding work to form a finished rubber tube. The extrusion and granulation operation mode of the double-stage extruder main body 101 is a very common conventional technology in the prior art, which will not be repeated here;
[0017] When the rubber raw material is put into the feeding part 102 and the two-stage extruder body 101 is started to perform extrusion granulation, the rotating seat 303 can be operated to rotate continuously, so that the rotating seat 303 drives the toggle rod 304 to rotate synchronously, and then the toggle rod 304 is used to continuously stir the crushed raw material inside the feeding part 102, so that the raw material can be gradually added to the two-stage extruder body 101 in a relative motion manner, thereby avoiding the crushed rubber raw material from being blocked in the feeding part 102 due to its own irregular shape and the large friction between them, thereby affecting the feeding effect, so as to achieve the purpose of stirring the raw material during the addition process and ensuring the continuous feeding effect.
[0018] like Figure 1 As shown:
[0019] The feeding portion 102 is in the shape of a frustum that is wide at the top and narrow at the bottom.
[0020] The frustum-shaped configuration of being wide at the top and narrow at the bottom enables the crushed rubber raw material to slide downward naturally and smoothly after being added to the feeding part 102 , thereby further achieving the purpose of ensuring a continuous feeding effect in cooperation with the continuously rotating rotating seat 303 and the toggle rod 304 .
[0021] like Figure 1 , Figure 2 and Figure 4-5 As shown:
[0022] It also includes a slide bar 301 slidably connected to the connecting frame 201 , and a rotating seat 303 is rotatably connected to the slide bar 301 .
[0023] When the rotating seat 303 is continuously rotated to make the toggle rod 304 stir the rubber raw material in the feeding part 102, the slide bar 301 can be operated to slide back and forth on the connecting frame 201, and the relative position of the slide bar 301 and the feeding part 102 can be continuously adjusted, thereby expanding the stirring range of the toggle rod 304, making it easier to use the toggle rod 304 to stir the rubber raw material in the feeding part 102, thereby further ensuring the continuous feeding effect.
[0024] like Figure 5 As shown:
[0025] It also includes an extension rod 305 slidably connected to the toggle rod 304 , and a compression spring is fixed between the toggle rod 304 and the extension rod 305 .
[0026] The setting of the extension rod 305 and the compression spring can ensure that during the rotation of the swivel seat 303, the extension rod 305 can always rest against the inner wall of the feeding part 102 to complete the subsequent stirring operation, thereby ensuring that the toggle rod 304 and the extension rod 305 can cooperate to fully stir the rubber raw material inside the feeding part 102, thereby further avoiding blockage and ensuring a continuous feeding effect.
[0027] like Figure 5 As shown:
[0028] It also includes a motor 302 fixedly connected to the slide bar 301 , and an output shaft of the motor 302 is fixedly connected to the rotating seat 303 .
[0029] When the rotating seat 303 needs to be rotated, the motor 302 can be started, and the output shaft of the motor 302 can be rotated, thereby driving the rotating seat 303 to rotate, and then the rotating toggle rod 304 is used to toggle the rubber material to achieve the subsequent effect of avoiding blockage.
[0030] like Figure 4-5 As shown:
[0031] The electric push rod 203 is also included and fixedly connected to the connecting frame 201 . The telescopic rod of the electric push rod 203 is fixedly connected to the sliding rod 301 .
[0032] When the slide bar 301 needs to be operated to slide, the telescopic rod of the electric push rod 203 can be extended and retracted, thereby pushing the slide bar 301 to move, thereby continuously changing the position of the slide bar 301, and then changing the stirring position of the toggle rod 304, thereby completing the comprehensive stirring work.
[0033] As shown in 4:
[0034] It also includes a connecting portion 202 fixedly connected to the connecting frame 201 , and a plurality of connecting threaded holes are formed on the connecting portion 202 .
[0035] The connecting frame 201 can be connected to the two-stage extruder body 101 by screwing bolts into a plurality of connecting threaded holes, thereby fixing the connecting frame 201 and achieving the subsequent effect of avoiding clogging.
[0036] like Figure 3 As shown:
[0037] The double-stage extruder also includes a base A103 and a base B104 fixedly connected to the double-stage extruder body 101 .
[0038] The arrangement of the base A103 and the base B104 allows the base A103 and the base B104 to be stably placed on the ground when the double-stage extruder body 101 is installed, thereby facilitating subsequent installation work.
[0039] like Figure 3 As shown:
[0040] The base A103 and the base B104 are both provided with fixing threaded holes 105 .
[0041] During installation, the base B104 and the base A103 can be fixed by screwing bolts into the fixing threaded holes 105, thereby fixing the entire device to complete the installation task.
[0042] like Figure 3 As shown:
[0043] There are multiple fixing threaded holes 105 .
[0044] The provision of multiple fixing threaded holes 105 can further increase the fixing stability and improve the installation effect.
