Description

Technical Field

[0001] The utility model relates to the field of rubber production and processing, in particular to a continuous mixing mill combined structure. Background Art

[0002] The open mixing mill is an open rubber mixing machine, which is a machine for mixing rubber between two rollers. The rubber particles or rubber blocks between the two rollers are heated and extruded through the two rollers, so that the raw materials roll on the roller surface and mix efficiently with the added raw materials. Multiple open mixing mills can form a production line, add multiple materials, and effectively mix and melt the raw materials.

[0003] After searching, a Chinese patent disclosed a continuous sheet discharging device for an open mill (publication number CN

[0004] 208867373U), this patented technology uses two open mills to continuously turn over and produce sheets, with the first open mill for rough refining and the second open mill for refining, which can avoid the waste of residual materials remaining in the first open mill and at the same time make the film density high;

[0005] However, in the comparative documents, the rubber is transported in a production line formed by two open mixing mills via an open conveyor belt, and the rubber surface is prone to hardening and solidification and becoming contaminated with dust, thereby reducing the rubber performance in subsequent continuous production processes.

[0006] Therefore, a continuous mixing mill assembly structure is proposed to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide a continuous open mixing mill assembly structure in order to solve the above-mentioned problem, thereby improving the problem that in the open mixing mill production line, the surface is easily hardened and solidified and contaminated with dust during transportation through an open conveyor belt, thereby reducing the rubber performance in the subsequent continuous production process.

[0008] The utility model achieves the above-mentioned purpose through the following technical scheme: a continuous open mill combined structure, a mounting seat, a roller is mounted on the inner wall of the mounting seat, and a collecting bucket is fixedly connected to the inner wall of the mounting seat; a discharging and conveying mechanism is arranged on one side of the collecting bucket for mixing and stirring the rubber during the transportation process; a gathering mechanism is arranged on one side of the roller for gathering and mixing the rubber on the surface of the roller; wherein a discharging assembly is arranged on one side of the mounting seat, and a stabilizing assembly is arranged on one side of the discharging assembly; the discharging assembly includes a stabilizing assembly fixedly connected to the collecting bucket; A mounting plate at the side end, the upper end of the mounting plate is fixedly connected to a first motor, the output end of the first motor is fixedly connected to a ball screw, the circumferential surface of the ball screw is threadedly connected to a first pushing slider, one side end of the first pushing slider is fixedly connected to a pushing plate, one side end of the pushing plate is fixedly connected to a spring, one end of the spring is fixedly connected to a scraper, the lower end of the collecting bucket is fixedly connected to a conveying auger, and the discharge assembly can stir and mix the rubber mechanically when transporting between multiple mixing mills during rubber production line processing, so that the rubber is not prone to surface solidification and hardening during transportation, and will not be contaminated by dust.

[0009] Preferably, one end of the conveying auger is fixedly connected with a guide port, and the inner wall of the guide port is an elongated rectangle. Through the elongated rectangular inner wall of the guide port, the rubber in the guide port can increase the contact effect and contact area with the roller when being discharged, thereby increasing the mixing effect of the roller.

[0010] Preferably, a heating block is fixedly connected to the inner wall of the conveying auger, and the rubber can be heated and stirred during transportation by the heating block, thereby increasing the rubber and mixing effect.

[0011] Preferably, the stabilizing assembly includes a telescopic rod fixedly connected to one side end of the pushing plate, one end of the telescopic rod is fixedly connected to the scraper, and the spring is sleeved on the circumferential surface of the telescopic rod. When the spring pushes the scraper to fit the surface of the roller to cut and discharge materials, the spring is prone to elastic deformation and damage. At this time, the spring is supported by the telescopic rod, so that the spring is not easily elastically deformed.

[0012] Preferably, a dovetail groove is provided at the upper end of the first motor, and a dovetail slider is fixedly connected to the lower end of the first pushing slider. The dovetail slider and the dovetail groove are slidably matched. When the ball screw pushes the first pushing slider to move, the first pushing slider is likely to shake along with the ball screw. At this time, the movement of the first pushing slider drives the dovetail slider to slide on the inner wall of the dovetail groove, so that the first pushing slider is not prone to shaking when moving.

[0013] Preferably, the gathering mechanism includes a blocking plate fixedly connected to the inner wall of one side of the mounting seat, the inner wall of the mounting seat is fixedly connected to a second motor, the output end of the second motor is fixedly connected to a reciprocating screw, the reciprocating screw is rotatably connected to the inner wall of the blocking plate, and the surface of the reciprocating screw is threadedly connected to two second pushing sliders. The rubber flattened on the surface of the roller can be gathered through the gathering mechanism to increase the mixing effect of the rubber and facilitate the discharge of the discharge component.

[0014] Preferably, the inner wall of the blocking plate is fixedly connected with a sliding rod, and the sliding rod slides through one side end of the two second push sliders and extends outward. When the reciprocating screw pushes the second push slider to move, the second push slider is prone to shaking. At this time, the movement of the second push slider is limited by the sliding rod, so that the second push slider is not prone to shaking when moving.

[0015] The beneficial effects of the utility model are:

[0016] 1. The mounting seat can drive the roller to rotate. At this time, the roller rotates and heats and melts the rubber raw materials. When the roller is finished mixing rubber, the rubber raw materials are transported through the discharge assembly. During the transportation process, the discharge assembly can continue to mix and stir the raw materials. At the same time, dust is not easy to enter, which reduces the degradation of rubber performance caused by dust and temperature changes during transportation. The stabilizing assembly makes the discharge assembly more stable during transportation. The gathering mechanism can gather and push the rubber on the surface of the roller, increase the mixing effect of the roller, and facilitate discharge;

[0017] 2. When the ball screw pushes the first push slider to move, the first push slider is likely to shake along with the ball screw. At this time, the movement of the first push slider drives the dovetail slider to slide on the inner wall of the dovetail groove, so that the first push slider is not likely to shake when moving.

[0024] When implementing: Figure 1-4 As shown, a continuous open mixing mill assembly structure comprises: a mounting base 1, a roller 6 is mounted on the inner wall of the mounting base 1, and a collecting bucket 2 is fixedly connected to the inner wall of the mounting base 1; a discharging and conveying mechanism 3, which is used for mixing and stirring the rubber during transportation and is arranged on one side of the collecting bucket 2; a gathering mechanism 5, which is used for gathering and mixing the rubber on the surface of the roller 6 and is arranged on one side of the roller 6; wherein, a discharging assembly 301 is arranged on one side of the mounting base 1, and a stabilizing assembly 302 is arranged on one side of the discharging assembly 301. When the rubber needs to be mixed and processed, the mounting base 1 can be started at this time, so that the mounting base 1 drives the roller 6 to rotate, and the roller 6 rotates and heats and melts the rubber at the same time. Raw materials, when roller 6 has finished mixing rubber and needs to be input to the next mixing mill, the rubber raw materials that have finished mixing are transported through the discharge component 301. During the transportation, the discharge component 301 can continue to mix and stir the raw materials, and dust is not easy to enter the mixture, thereby reducing the degradation of rubber performance caused by dust and temperature changes during transportation. The stabilizing component 302 can make the discharge component 301 more stable during transportation, and the gathering mechanism 5 can gather and push the rubber on the surface of the roller 6 to increase the mixing effect of the roller 6 and facilitate discharge. The mounting base 1 includes a driving gear set and a mounting frame, etc.; for the staff in this technical field, the mounting base 1 and the roller 6 are both prior art and will not be elaborated on here.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, the discharge assembly 301 includes a mounting plate 3018 fixedly connected to one side end of the collecting bucket 2, the upper end of the mounting plate 3018 is fixedly connected to the first motor 3011, the output end of the first motor 3011 is fixedly connected to the ball screw 3012, the circumferential surface of the ball screw 3012 is threadedly connected to the first push slider 3013, one side end of the first push slider 3013 is fixedly connected to a push plate 3014, one side end of the push plate 3014 is fixedly connected to a spring 3015, one end of the spring 3015 is fixedly connected to a scraper 3016, the lower end of the collecting bucket 2 is fixedly connected to a conveying auger 3017, when the roller 6 completes the rubber mixing, at this time, by starting the first motor 301 1, the first motor 3011 drives the ball screw 3012 to rotate, and the ball screw 3012 drives the first push slider 3013 to move, pushing the spring 3015 and the scraper 3016 to fit the surface of the roller 6, scraping the rubber on the surface of the roller 6 and dropping it into the collecting bucket 2, at this time, the conveying auger 3017 is started to transport the raw materials to the upper side of the next roller 6. For the staff in this technical field, the first motor 3011 and the first motor 3011 are both prior art, and will not be described in detail here. One end of the conveying auger 3017 is fixedly connected with a guide port 7, and the inner wall of the guide port 7 is a long rectangle. The discharge of the conveying auger 3017 can be guided through the guide port 7, and the rubber output at the same time The conveying auger 3017 is a long rectangle, which is more in line with the surface of the roller 6, thereby increasing the mixing effect of the roller 6 on the raw materials. The inner wall of the conveying auger 3017 is fixedly connected with a heating block 4, through which the raw materials can be heated when the conveying auger 3017 conveys the raw materials, thereby increasing the mixing effect of the raw materials when being transported in the conveying auger 3017. The stabilizing component 302 includes a telescopic rod 3023 fixedly connected to one side end of the pushing plate 3014, one end of the telescopic rod 3023 is fixedly connected to the scraper 3016, and the spring 3015 is sleeved on the circumferential surface of the telescopic rod 3023. When the spring 3015 pushes the scraper 3016 to fit the surface of the roller 6 for cutting and discharging, the spring 3015 is prone to elastic deformation and damage. At this time, the spring 3015 is supported by the telescopic rod 3023, so that the spring 3015 is not easily elastically deformed, and a dovetail groove 3021 is provided at the upper end of the first motor 3011, and a dovetail slider 3022 is fixedly connected to the lower end of the first pushing slider 3013, and the dovetail slider 3022 and the dovetail groove 3021 are slidably matched. When the ball screw 3012 pushes the first pushing slider 3013 to move, the first pushing slider 3013 is easy to shake with the ball screw 3012. At this time, the first pushing slider 3013 moves and drives the dovetail slider 3022 to slide on the inner wall of the dovetail groove 3021, so that the first pushing slider 3013 is not easy to shake when moving.

[0026] like Figure 3 and Figure 4As shown, the gathering mechanism 5 includes a blocking plate 505 fixedly connected to the inner wall of one side of the mounting seat 1, the inner wall of the mounting seat 1 is fixedly connected with a second motor 502, the output end of the second motor 502 is fixedly connected with a reciprocating screw 501, the reciprocating screw 501 is rotatably connected to the inner wall of the blocking plate 505, and the surface of the reciprocating screw 501 is threadedly connected with two second push sliders 503. When the rubber on the surface of the roller 6 is squeezed and diffused, the subsequent mixing effect of the roller 6 is reduced, and it is inconvenient to discharge the material, the second motor 502 can be driven at this time, so the second motor 502 drives the reciprocating screw 501 to rotate, and the reciprocating screw 501 drives the two second push sliders 503 to slide. The reciprocating screw 501 is a form of a three-dimensional cam pair, which is manifested as two thread grooves with the same pitch and opposite rotation. The two ends are connected by a transition curve. Through the rotation of the reciprocating screw 501, the side of the spiral groove pushes the slider placed in the spiral groove to make axial reciprocating motion. The two sections of the spiral grooves on the surface of the two reciprocating screws 501 push in opposite directions. At this time, the two second pushing sliders 503 push the raw materials to move toward the center of the roller 6 to gather and increase the mixing effect. For the staff in this technical field, the second motor 502 is a prior art and will not be described in detail here. The inner wall of the blocking plate 505 is fixedly connected with a sliding rod 504, and the sliding rod 504 slides through one side end of the two second pushing sliders 503 and extends outward. When the reciprocating screw 501 pushes the second pushing slider 503 to move, the second pushing slider 503 is prone to shaking. At this time, the movement of the second pushing slider 503 is limited by the sliding rod 504, so that the second pushing slider 503 is not easy to shake when moving.

[0027] When the utility model is in use, when it is necessary to process rubber, the mounting seat 1 can be started, so that the mounting seat 1 drives the roller 6 to rotate, and the roller 6 rotates and heats and melts the rubber raw material at the same time for mixing. At this time, the second motor 502 drives the reciprocating screw 501 to rotate, and the reciprocating screw 501 drives the two second push sliders 503 to slide back and forth, so as to gather the mixed and spread rubber and increase the condensation effect. When the roller 6 is finished mixing and needs to be input to the next open mill, the first motor 3011 is started at this time, and the first motor 3011 is started. The machine 3011 drives the ball screw 3012 to rotate, and the ball screw 3012 drives the first push slider 3013 to move, pushing the spring 3015 and the scraper 3016 to fit the surface of the roller 6, scraping the rubber on the surface of the roller 6 and dropping it into the collecting bucket 2. At this time, the conveying auger 3017 is started to transport the raw materials to the upper side of the next roller 6. At the same time, the heating block 4 heats the inside of the conveying auger 3017. The conveying auger 3017 transports and mixes the internal raw materials at the same time. At the same time, dust is not easy to enter, reducing the degradation of rubber performance due to dust and temperature changes during transportation.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
