Description

Technical Field

[0001] This invention relates to the field of open mills, specifically an open mill that facilitates material feeding. Background Technology

[0002] The open mill is one of the earliest plastic mixing machines used in plastic product manufacturing plants. On a calendering production line, the open mill, positioned before the calender and after the mixer, functions to mix and plasticize uniformly blended raw materials, providing a uniformly mixed molten material for the calendering process. In cable material production, the open mill can directly plasticize pre-mixed powdered materials into a molten material, which is then pressed into sheets or strips for pelletizing. On floor covering production lines, it can directly provide a uniformly mixed and plasticized undercoat for fabric leather. It can also reprocess recycled waste plastic film (sheets) on the open mill. The open mill mainly consists of two horizontally arranged hollow or perforated rollers, a frame, a spacing adjustment device, and a transmission device. The open mill uses two counter-rotating rollers to extrude and shear the material. The material is subjected to strong shearing and frictional forces in the gap between the rollers, thus achieving the purpose of plasticizing or mixing. The roller temperature, pressure, and rotation speed can be adjusted according to different needs.

[0003] However, after being extruded, the rubber in the open mill needs to be manually mixed and turned over in a high-temperature environment. Repeatedly turning over the rubber raw material can cause the operator to be burned. Summary of the Invention

[0004] To address the existing problems, the present invention provides an open mill that facilitates material feeding. When used in conjunction with this device, it can effectively solve the problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A two-roll mill for easy feeding includes a two-roll mill, comprising: a mounting base, a rotating base, and an extrusion roller. A feeding mechanism is mounted on one side of the extrusion roller on the upper surface of the two-roll mill. A climbing frame is provided inside the feeding mechanism, and a vertical groove is formed inside the climbing frame. A feeding motor is mounted on the upper end of the feeding mechanism, and a reciprocating lead screw is connected to the lower end of the feeding motor. A guide slide is provided below the reciprocating lead screw, and a lead screw moving sleeve is mounted on the side surface of the guide slide outside the reciprocating lead screw. A support rod is provided in front of the guide slide, and a rotating groove is formed at the end of the guide slide. A second elastic rotating shaft is mounted inside the rotating groove at the end of the support rod. A first magnetic suction pad is mounted on the upper surface of the support rod. A storage box is mounted directly below the extrusion roller on the upper surface of the mounting base, and a second magnetic suction pad is mounted on the side of the storage box near the first magnetic suction pad.

[0007] As a further embodiment of the present invention: roller adjustment seats are installed on the outer sides of both ends of the extrusion roller, and a limit groove is opened on the inner side wall of the rotating seat corresponding to the outer side of the roller adjustment seat. Adjustment bolts are installed between the inside of the rotating seat and the roller adjustment seat.

[0008] As a further embodiment of the present invention: a material guiding mechanism is installed on the upper surface of the rotating seat, the material guiding mechanism including: a longitudinal support rod and a first elastic rotating shaft, a roller mounting frame is installed on the outer side of the first elastic rotating shaft, and a clamping roller is installed at the lower end of the roller mounting frame.

[0009] As a further embodiment of the present invention: a drive gear is installed on one side of the extrusion roller, and a drive motor is connected to the end of the drive gear via a rotating shaft. A lifting base is installed below the drive motor on the upper surface of the mounting base, and an electrical control mechanism is installed on one side of the lifting base on the upper surface of the mounting base.

[0010] As a further embodiment of the present invention: an adjusting sleeve is installed below the material guiding mechanism on the upper surface of the rotating seat, and a roller partition is installed inside the adjusting sleeve.

[0011] As a further embodiment of the present invention: the guide slide rod is rotatably connected to the support rod through the second elastic pivot, and the upper surface of the support rod at the end near the storage box is provided with an oblique guide groove.

[0012] As a further embodiment of the present invention: the lead screw moving sleeve is meshed and rotatably connected to the reciprocating lead screw, the guide slide is slidably connected to the feeding motor, and the feeding mechanism is fixedly connected to the mounting base.

[0013] As a further embodiment of the present invention: the roller adjusting seat is slidably connected to the limiting groove, the outer end of the extrusion roller is equipped with a rotating bearing inside the roller adjusting seat, and the adjusting bolt is rotatably connected to the rotating seat.

[0014] As a further embodiment of the present invention: the longitudinal support rod is fixedly connected to the rotating seat, and the roller mounting frame is fixedly connected to the first elastic rotating shaft.

[0015] As a further embodiment of the present invention: a heating mechanism is installed on the upper surface of the mounting base at the end of the extrusion roller away from the electronic control mechanism.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The feeding mechanism can be adjusted to a height position between the clamping roller and the extrusion roller. By controlling the entire collection box to press down, the support rod below the collection box will rotate downwards inside the rotating groove via the elastic rotating shaft. This allows the material collected inside the collection box to be pushed downwards and then pushed into the gap between the two extrusion rollers. After being pushed away, the collection box located above the support rod is pulled out. Then, the feeding motor continues to drive the reciprocating screw to rotate, and the guide slide is adjusted to descend to the lowest position. The collection box is then pushed towards the support rod. This operation is repeated until the small volume of raw material is heated and extruded until it is fused, and then it is discharged downwards again from inside the feeding mechanism.

[0018] 2. After the second magnetic pad at the end of the storage box is attached to the first magnetic pad, the feeding motor is started to drive the reciprocating screw to rotate. Therefore, when the storage box is placed above the support rod, it can prevent it from falling. At the same time, the support rod and the rotating groove can be adjusted by the elastic shaft, and the feeding can be manually controlled.

[0019] 3. When using a long sheet of raw material, one end of the material is passed through the inside of two clamping rollers. The clamping rollers are supported by the roller mounting frame and the elastic rotating shaft at the upper end of the longitudinal support rod. The two extrusion rollers rotate relative to each other to pull the material downward as a whole. The upper guide mechanism can be used for support. The user does not need to support the material. At the same time, the guide mechanism on one side can isolate the material at the rear.

[0020] 4. By controlling the torque applied to the adjusting bolt, and controlling the roller adjusting seat at the end of one extrusion roller to slide within the limiting groove, the distance between the two extrusion rollers is controlled, which can ensure that the raw material can be heated and extruded when the two extrusion rollers rotate relative to each other.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0031] In the description of this specification, references to terms such as "this embodiment," "some embodiments," "example," "specific example," or "some examples" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example, and the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] like Figure 1-8As shown, this embodiment provides a two-roll mill for easy feeding, including a two-roll mill 1. The two-roll mill 1 includes: a mounting base 2, a rotating seat 3, and an extrusion roller 4. A feeding mechanism 8 is mounted on one side of the extrusion roller 4 on the upper surface of the two-roll mill 1. A climbing frame 801 is provided inside the feeding mechanism 8. A vertical groove 803 is provided inside the climbing frame 801. A feeding motor 802 is mounted on the upper end of the feeding mechanism 8, and a reciprocating screw 8 is connected to the lower end of the feeding motor 802. 05. A guide slide 804 is provided below the reciprocating lead screw 805. The guide slide 804 is slidably connected to the feeding motor 802. The feeding mechanism 8 is fixedly connected to the mounting base 2. A lead screw moving sleeve 806 is installed on the side surface of the guide slide 804 outside the reciprocating lead screw 805. The lead screw moving sleeve 806 is meshed and rotatably connected to the reciprocating lead screw 805. A support rod 807 is provided in front of the guide slide 804. The end of the guide slide 804 is provided with... A second elastic rotating shaft 810 is installed inside the rotating groove 809 and the end of the support rod 807. The guide slide rod 804 is rotatably connected to the support rod 807 through the second elastic rotating shaft 810. An inclined guide groove 808 is opened on the upper surface of the end of the support rod 807 near the storage box 10. A first magnetic suction pad 811 is installed on the upper surface of the support rod 807. The storage box 10 is installed directly below the extrusion roller 4 on the upper surface of the mounting base 2. The second elastic rotating shaft 810 has a large elasticity, which can prevent the extruded material from being directly deflected under its own weight when it is placed inside the storage box 10. A second magnetic suction pad 1001 is installed on the side of the storage box 10 near the first magnetic suction pad 811. At the same time, after the second magnetic suction pad 1001 and the first magnetic suction pad 811 are attracted together, it can also prevent the storage box 10 from falling off from above after the support rod 807 is rotated.

[0033] like Figure 1-6As shown, in this embodiment, roller adjusting seats 301 are installed on the outer sides of both ends of the extrusion roller 4. A limiting groove 303 is formed on the inner sidewall of the rotating seat 3 corresponding to the outer side of the roller adjusting seat 301. The roller adjusting seat 301 and the limiting groove 303 are slidably connected. An adjusting bolt 302 is installed between the inside of the rotating seat 3 and the roller adjusting seat 301. The adjusting bolt 302 is meshed and rotatably connected to the rotating seat 3. A guiding mechanism 7 is installed on the upper surface of the rotating seat 3. An adjusting sleeve 12 is installed below the guiding mechanism 7 on the upper surface of the rotating seat 3. A roller partition 11 is installed inside the adjusting sleeve 12. The guiding mechanism 7 includes: a longitudinal support rod. 701. A first elastic rotating shaft 702 is provided. A roller mounting frame 703 is installed on the outer side of the first elastic rotating shaft 702. A longitudinal support rod 701 is fixedly connected to the rotating seat 3. The roller mounting frame 703 is fixedly connected to the first elastic rotating shaft 702. A clamping roller 704 is installed at the lower end of the roller mounting frame 703. The two clamping rollers 704 can rotate using the roller mounting frame 703 on the first elastic rotating shaft 702. When the raw material is placed between the two clamping rollers 704, the roller mounting frame 703 will clamp it under the reset force of the first elastic rotating shaft 702, which can ensure that the raw material will be vertically aligned between the gaps between the two extrusion rollers 4.

[0034] like Figure 7-8 As shown, in this embodiment, a drive gear 401 is installed on one side of the extrusion roller 4, and a rotating bearing is installed inside the roller adjustment seat 301 on the outer side of the extrusion roller 4. The extrusion roller 4 can rotate freely inside the roller adjustment seat 301 using the rotating bearing, and the roller adjustment seat 301 can adjust the position and spacing inside the limiting slide groove 303. The end of the drive gear 401 is connected to the drive motor 6 through a rotating shaft. A lifting base 13 is installed below the drive motor 6 on the upper surface of the mounting base 2. An electrical control mechanism 9 is installed on one side of the lifting base 13 on the upper surface of the mounting base 2. A heating mechanism 5 is installed on the upper surface of the mounting base 2 at the end of the extrusion roller 4 away from the electrical control mechanism 9. The heating mechanism 5 can be used to heat and control the temperature of the extrusion roller 4 to ensure the heating and deformation of the raw material.

[0035] The working principle of this invention is as follows: During use, the feeding method can be selected according to the size of the raw material to be processed. When using a long sheet of raw material, one end of the material is passed through the interior of two clamping rollers 704. The clamping rollers 704 utilize the support of the roller mounting bracket 703 and the first elastic rotating shaft 702 at the upper end of the longitudinal support rod 701 to place the end of the raw material between the two extrusion rollers 4. The heating mechanism 5 is controlled to set the two extrusion rollers 4 to the processing temperature, and torque is applied to the adjusting bolt 302. After the roller adjusting seat 301 at the end of one extrusion roller 4 slides within the limiting groove 303, the distance between the two extrusion rollers 4 is controlled, ensuring that the material is properly positioned within the two extrusion rollers. When the rollers 4 rotate relative to each other, they can heat and extrude the raw material. The electric control mechanism 9 drives the drive motor 6 to apply force to the extrusion rollers 4, thereby achieving the meshing rotation of the two drive gears 401 to control the transmission and extrusion of the raw material. After the raw material is extruded and heated from inside the extrusion rollers 4, it falls into the lower storage box 10. The storage box 10 is then pulled out as a whole and placed above the guiding mechanism 7. When holding smaller raw materials, they are placed directly from above the gap between the two extrusion rollers 4, falling into the storage box 10 after extrusion. After most of the heated and extruded raw material falls into the storage box 10, the storage box 10 is pushed towards the upward feeding mechanism 8. An opening is made at the end of the support rod 807. The inclined guide groove 808 facilitates the upward movement of the storage box 10. After the storage box 10 is moved and placed above the support rod 807, the second magnetic suction pad 1001 at the end of the storage box 10 will be attracted and connected to the first magnetic suction pad 811. Then, the feeding motor 802 drives the reciprocating screw 805 to rotate. The rotating feeding motor 802 will engage with the screw moving sleeve 806 on the side surface of the guide slide rod 804, thereby controlling the guide slide rod 804 to move upward inside the vertical slide groove 803. After the guide slide rod 804 and the support rod 807 together drag the storage box 10 to the upper position, the height of the storage box 10 is controlled to be between the clamping roller 704 and the extrusion roller 4. Then, the other... A storage box 10 is placed below the extrusion roller 4. By pressing the storage box 10 downwards, the support rod 807 below the storage box 10 will rotate downwards inside the rotating groove 809 via the second elastic rotating shaft 810. This allows the material collected inside the storage box 10 to be pushed downwards and then pushed into the gap between the two extrusion rollers 4. After being pushed away, the storage box 10, located above the support rod 807, is pulled out. Then, the feeding motor 802 is controlled to drive the reciprocating screw 805 to rotate, and the guide slide 804 is adjusted to descend to the lowest position. The storage box 10 is then pushed towards the support rod 807. This process is repeated until the small volume of raw material is heated and extruded until it is fused. Then, the material is released downwards from inside the feeding mechanism 7.
