Description

Technical Field

[0001] The invention relates to the field of open mixing mills, in particular to an open mixing mill which is convenient for loading materials. Background Art

[0002] The open mill is a kind of mixing plastic equipment that was used earlier by plastic product manufacturers. On the calender production line, the open mill is before the calender and after the mixer. Its function is to mix and plasticize the uniformly mixed raw materials, and provide a relatively uniform molten material for the calender to calender and mold plastic products. When producing cable materials, the open mill can directly plasticize the powdered materials mixed according to the formula into molten materials, and then press them into sheet strips, so that the pelletizer can cut them into granules. On the floor leather production line, it can directly provide a uniformly mixed and plasticized base coating for cloth leather, and can also re-refine and plasticize the recycled waste plastic film (sheet) on the open mill. The open mill is mainly composed of two horizontally arranged hollow or drilled rollers and a frame, a spacing device, and a transmission device. The open mill squeezes and shears the materials through two rollers rotating in opposite directions. The materials are subjected to strong shearing and friction forces in the gap between the rollers, thereby achieving the purpose of plasticization or mixing. Parameters such as the temperature, pressure and speed of the rollers can be adjusted according to different needs.

[0003] However, the rubber in the mixing mill needs to be manually mixed and turned over in a high temperature environment after extrusion, and turning the rubber raw materials many times will cause the operator to be burned. Summary of the invention

[0004] In view of the existing problems, the present invention provides an open mixing mill which is convenient for loading materials. The device can effectively solve the problems raised in the background technology when used in combination.

[0005] To solve the above problems, the present invention adopts the following technical solutions: The top end of the lifting mechanism is connected with the lifting of the lifting mechanism, and the bottom end of the lifting mechanism is connected with the lifting of the lifting mechanism, and the bottom end of the lifting mechanism is connected with the lifting of the lifting mechanism.

[0006] As a further solution of the present invention: roller adjustment seats are installed on the outer sides of both ends of the extrusion roller, a limiting slide groove is provided on the inner side wall of the rotating seat corresponding to the outer side of the roller adjustment seat, and an adjustment bolt is installed between the inside of the rotating seat and the roller adjustment seat.

[0007] As a further solution of the present invention: a material guiding mechanism is installed on the upper surface of the rotating seat, and the material guiding mechanism includes: a longitudinal support rod, an elastic rotating shaft, a roller mounting frame is installed on the outer side of the elastic rotating shaft, and a clamping roller is installed on the lower end of the roller mounting frame.

[0008] As a further solution of the present invention: a driving gear is installed on one side end of the extrusion roller, and the end of the driving gear is connected to a driving motor through a rotating shaft, a lifting base is installed on the upper surface of the mounting base below the driving motor, and an electric control mechanism is installed on one side of the lifting base on the upper surface of the mounting base.

[0009] As a further solution of the present invention: a positioning sleeve is installed on the upper surface of the rotating seat below the material guiding mechanism, and a roller partition is installed inside the positioning sleeve.

[0010] As a further solution of the present invention: the support rod is rotatably connected to the support rod through the elastic shaft, and an oblique guide groove is formed on the upper surface of one end of the support rod close to the storage box.

[0011] As a further solution of the present invention: the screw moving sleeve is meshed and rotatably connected with the reciprocating screw, the guide slide rod is slidably connected with the feeding motor, and the feeding mechanism is fixedly connected with the mounting base.

[0012] As a further solution of the present invention: the roller adjustment seat is slidingly connected to the limiting slide groove, the outer end of the extrusion roller is located inside the roller adjustment seat and a rotating bearing is installed, and the adjustment bolt is meshed and rotatably connected with the rotating seat.

[0013] As a further solution 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 elastic rotating shaft.

[0014] As a further solution of the present invention: a heating mechanism is installed on the upper surface of the mounting base at one end of the squeezing roller away from the electric control mechanism.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The feeding mechanism can be adjusted to the height position between the clamping roller and the extrusion roller. The storage box is controlled to be pressed downward as a whole, and the support rod under the storage box will rotate downward inside the rotating groove through the elastic shaft. The materials collected in the storage box can be pushed downward and then to the gap between the two extrusion rollers. After the pulling is completed, the storage box located above the support rod is pulled out, and the feeding motor is continued to control the rotation of the reciprocating screw rod, and the guide slide rod is adjusted to drop to the lowest position, and the storage box is pushed toward the direction of the support rod. The operation is repeated until the small volume of raw materials is heated, extruded and fused, and then the materials are discharged downward from the inside of the material guide mechanism again.

[0016] 2. After the second magnetic pad at the end of the storage box is integrally adsorbed and connected to the first magnetic pad, the feeding motor is started to drive the reciprocating screw to rotate. Therefore, when the storage box is placed on top of the support rod, it can be prevented from falling. At the same time, the support rod and the rotating groove can adjust the rotation angle through the elastic rotating shaft, and the discharge can be manually controlled.

[0017] 3. When a whole long piece of raw material is used, one end of the raw material is passed through the inside of the two clamping rollers. The clamping rollers use the support of the roller mounting frame and the elastic shaft at the upper end of the longitudinal support rod, and use the two squeezing rollers to rotate relative to each other to pull the raw material downward as a whole, while the material guide mechanism at the upper position can be used for supporting processing. The user does not need to support the raw material. At the same time, the material guide mechanism at one side can isolate the raw material at the rear.

[0018] 4. Control the torque applied to the adjusting bolt, control the roller adjusting seat at the end of one extrusion roller to slide within the limiting slide groove, and then control the distance between the two extrusion rollers to ensure that the raw materials can be heated and extruded when the two extrusion rollers rotate relative to each other.

The support rod 807 is rotatably connected through the support rod 807 through the elastic rotating shaft 810. An inclined guide groove 808 is provided on the upper surface of the end of the support rod 807 close to the storage box 10, and a first magnetic pad 811 is installed on the upper surface of the support rod 807. The storage box 10 is installed on the upper surface of the mounting base 2 just below the extrusion roller 4. The elastic rotating shaft 810 has a large elasticity. When the extruded raw material is placed inside the storage box 10, it can prevent it from directly deflecting under the action of its own gravity. A second magnetic pad 1001 is installed on the side end of the storage box 10 close to the first magnetic pad 811. At the same time, after the second magnetic pad 1001 and the first magnetic pad 811 are integrally adsorbed, it can also prevent the storage box 10 from falling off from the top after the control of the overall rotation of the support rod 807.

[0024] like Figure 1-6As shown, in this embodiment, roller adjustment seats 301 are installed on the outer sides of both ends of the squeezing roller 4, and the inner side wall of the rotating seat 3 is provided with a limited sliding groove 303 corresponding to the outer side of the roller adjustment seat 301, and the roller adjustment seat 301 is slidingly connected with the limited sliding groove 303, and an adjustment bolt 302 is installed between the inside of the rotating seat 3 and the roller adjustment seat 301, and the adjustment bolt 302 is meshed and rotatably connected with the rotating seat 3, and a material guide mechanism 7 is installed on the upper surface of the rotating seat 3, and an adjustment sleeve 12 is installed on the upper surface of the rotating seat 3 below the material guide mechanism 7, and a roller partition 11 is installed inside the adjustment sleeve 12, and the material guide mechanism 7 includes: A longitudinal support rod 701 and an elastic rotating shaft 702, a roller mounting frame 703 is installed on the outer side of the elastic rotating shaft 702, the longitudinal support rod 701 is fixedly connected to the rotating seat 3, the roller mounting frame 703 is fixedly connected to the elastic rotating shaft 702, and a clamping roller 704 is installed at the lower end of the roller mounting frame 703. The two clamping rollers 704 can be rotated on the elastic rotating shaft 702 by using the roller mounting frame 703. When the raw material is placed between the two clamping rollers 704, the roller mounting frame 703 will clamp it under the resetting force of the elastic rotating shaft 702, which can ensure that the raw material will vertically correspond to the gap between the two extrusion rollers 4.

[0025] like Figure 7-8 As shown, in this embodiment, a driving gear 401 is installed on one side end of the extrusion roller 4, and a rotating bearing is installed on the outer end of the extrusion roller 4 located inside the roller adjustment seat 301. The extrusion roller 4 can rotate freely inside the roller adjustment seat 301 as a whole by utilizing 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 driving gear 401 is connected to the driving motor 6 through a rotating shaft, and a lifting base 13 is installed on the upper surface of the mounting base 2 below the driving motor 6. An electric control mechanism 9 is installed on one side of the lifting base 13 located 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 one end of the extrusion roller 4 away from the electric control mechanism 9. The heating mechanism 5 as a whole can be used to heat the extrusion roller 4 to control the pressurized temperature to ensure heating and deformation of the raw material.

[0026] The working principle of the present invention is as follows: when in use, the method of discharging the materials can be selected according to the size of the materials to be operated. When a whole long piece of material is used, one end of the material is passed through the inside of two clamping rollers 704, and the clamping rollers 704 use the support of the roller mounting frame 703 and the elastic rotating shaft 702 at the upper end position of the longitudinal support rod 701, and place the end of the material between the two squeezing rollers 4, and control the heating mechanism 5 to set the two squeezing rollers 4 to the processing temperature, and use the control to apply a torque to the adjusting bolt 302, and control the roller adjusting seat 301 at the end of one squeezing roller 4 to slide within the limiting slide groove 303, and then control the spacing between the two squeezing rollers 4, so as to ensure that the two squeezing rollers 4 are in a state of being pressed. 4 can heat and extrude the raw material when it rotates relative to the extrusion roller 4. After the electric control mechanism 9 drives the driving motor 6 to apply force to the extrusion roller 4, the meshing rotation of the two driving gears 401 is realized to control the transmission and extrusion of the raw material. After the raw material is extruded and heated from the inside of the extrusion roller 4, it falls into the inside of the storage box 10 below. After the storage box 10 is pulled out as a whole and placed on the top of the material guide mechanism 7 again, when the clamped raw material is small, the raw material is directly placed from the upper position of the gap between the two extrusion rollers 4. After extrusion, it falls into the inside of the storage box 10. When most of the raw materials are heated and extruded and fall into the inside of the storage box 10, the storage box 10 is pushed to move in the direction of the upward feeding mechanism 8, and a support is opened at the end of the support rod 807. The inclined guide groove 808 can facilitate the upward movement of the storage box 10. After the storage box 10 is moved as a whole to the upper position of the support rod 807, the second magnetic pad 1001 at the end of the storage box 10 will be integrally adsorbed and connected with the first magnetic pad 811. The reciprocating screw rod 805 is driven to rotate by starting the feeding motor 802. The rotating feeding motor 802 will engage with the screw moving sleeve 806 on the side surface of the guide slide bar 804, thereby controlling the guide slide bar 804 to move upward inside the vertical slide groove 803. After the guide slide bar 804 and the support rod 807 drag the storage box 10 to the upper position as a whole, the height of the storage box 10 is controlled to be between the clamping roller 704 and the squeezing roller 4, and then the other side is moved. Another storage box 10 is placed below the extrusion roller 4. The storage box 10 is controlled to be pressed downward as a whole, and the support rod 807 below the storage box 10 will rotate downward inside the rotating groove 809 through the elastic rotating shaft 810. The materials collected in the storage box 10 can be pushed downward and then to the gap between the two extrusion rollers 4. After the materials are pulled away, the storage box 10 located above the support rod 807 is pulled away, and the feeding motor 802 is controlled to drive the rotation of the reciprocating screw 805, and the guide slide bar 804 is adjusted to drop to the lowest position, and the storage box 10 is pushed toward the direction of the support rod 807. The operation is repeated until the small volume of raw materials is heated, extruded and fused, and then the materials are discharged downward from the inside of the material guide mechanism 7 again.
