A material stripping device for roller of mixing mill

Abstract

This utility model relates to the field of open mill technology, specifically to an open mill roller material stripping device, including a frame, a front roller and a rear roller rotatably connected to the frame, and a stripping assembly slidably connected to the frame for stripping rubber material from the front roller. The stripping assembly slides close to the front roller surface, and the stripping blade abuts against the front roller surface, cutting the rubber material wrapped on the front roller so that the rubber material is cut off and stripped along the edge of the blade. Due to gravity, the rubber material bends downward and contacts the rotating demolding roller. The demolding roller, through its own rotation, drives the rubber material to be stripped from the front roller for discharge. This method makes the stripping of the rubber material less likely to cause breakage. When the rubber material is still sticking to the front roller, the stripping blade located above the demolding roller and abutting against the front roller surface performs the stripping function, enhancing the product's fault tolerance. It is quick and easy to use, allowing the rubber material to separate well from the front roller and avoiding sticking to the roller.

Description

Technical Field

[0001] The utility model relates to the technical field of open mixing mills, in particular to a roller material stripping device for an open mixing mill. Background Art

[0002] Open mixing mill, which is the abbreviation of open rubber mixing mill, is a kind of rubber mixing machine with exposed rollers, which is often used in rubber factories to prepare plasticized rubber and mixed rubber or to perform hot mixing and molding. The open mixing mill in the prior art usually uses two rollers with opposite rotation directions and different rotation speeds to roll the plastic between the two rollers and apply strong shear force to achieve the purpose of plasticating or mixing.

[0003] During the operation of the mixing mill, due to the different properties of the rubber, the rubber will cover the roller when it is pressed into sheets through the roller gap. Manual intervention is required to peel off the rubber covering the roller. During discharging, the rubber may stick to the roller, resulting in unsmooth discharging, which requires manual supervision. With the continuous development of rubber technology, the requirements for the degree of automation of mixing mill operations are becoming higher and higher.

[0004] Therefore need to propose a kind of new scheme to supplement the existing mixing mill. Utility Model Content

[0005] The utility model aims to solve the above problems and provides a material stripping device for a mixing mill roller.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a material stripping device for a mixing mill roller comprises a frame, a front roller and a rear roller rotatably connected to the frame, and is characterized in that: the frame is slidably connected to a stripping component that can strip the rubber material on the front roller, the stripping component comprises a stripping knife, a connecting frame and a distance adjusting member, the connecting frame is fixedly connected to the stripping knife, the connecting frame is movably connected to the frame, the two ends of the connecting frame are respectively movably connected to the distance adjusting member, the stripping knife can form an abutment with the front roller, and the stripping component also comprises a demoulding roller, and the demoulding roller is relatively rotatably connected to the connecting frame.

[0007] Preferably, the blade provided on the stripping knife is a composite blade.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the stripping component slides close to the roller surface of the front roller, the blade of the stripping knife abuts against the roller surface of the front roller, and the rubber wrapped on the front roller is cut so that the rubber is cut and stripped along the edge of the blade, and is bent downward due to gravity and contacts the rotating demoulding roller. At this time, the demoulding roller drives the rubber to be stripped from the front roller through its own rotation for discharging, and the discharging is carried out in an orderly manner. The distance between the demoulding roller and the front roller is closer than the existing belt during discharging, and the stripping of the rubber is less likely to cause breakage. When the rubber is still stuck to the front roller, the stripping knife located above the demoulding roller and abutting against the roller surface of the front roller plays a stripping role, thereby enhancing the fault tolerance of the product. It is quick and simple to use, so that the rubber can be well separated from the front roller to avoid the occurrence of sticking to the roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0013] like Figure 1 , Figure 2As shown, a material stripping device for a mixing mill roller comprises a frame 1, a front roller 2 and a rear roller 3 rotatably connected to the frame 1, the frame 1 is slidably connected with a stripping component that can strip the rubber material on the front roller 2, when the mixing mill is started, the front roller 2 and the rear roller 3 cooperate to pre-mix, eat, disperse and mix the rubber material before discharging, at this time, by controlling the stripping component slidably connected to the frame 1 to slide close to the roller surface of the front roller 2, the blade 8 of the stripping knife 4 abuts against the roller surface of the front roller 2, and the rubber material wrapped on the front roller 2 is cut so that the rubber material is cut off and stripped along the edge of the blade 8. , it bends downward due to gravity and contacts with the rotating demoulding roller 7. At this time, the demoulding roller 7 drives the rubber material to be peeled off from the front roller 2 through its own rotation for discharging, and the discharging is carried out in an orderly manner. The distance between the demoulding roller 7 and the front roller 2 is closer than the existing belt during discharging, and the rubber material is less likely to be broken when being peeled off. When the rubber material is still adhered to the front roller 2, the stripping knife 4 located above the demoulding roller 7 and in contact with the roller surface of the front roller 2 plays a stripping role, which enhances the fault tolerance of the product. It is quick and simple to use, so that the rubber material can be well separated from the front roller 2 to avoid the occurrence of sticking to the roller.

[0014] like Figure 1 , Figure 2 As shown, the stripping assembly includes a stripping knife 4, a connecting frame 5 and a distance adjusting member 6. The connecting frame 5 is fixedly connected to the stripping knife 4, and the connecting frame 5 is movably connected to the frame 1. The two ends of the connecting frame 5 are movably connected to the distance adjusting members 6. The stripping knife 4 can form an abutment with the front roller 2. The movement of the connecting frame 5 is controlled by the distance adjusting member 6, so that the stripping knife 4 is close to the front roller 2 to strip the rubber material. The distance adjusting member 6 can avoid the danger of workers getting involved when operating too close manually, such as a screw rod, etc. The stripping knife 4 forms an abutment with the front roller 2 to form a shear stress, so as to cut off the rubber material coated on the front roller 2. The blade 8 on the stripping knife 4 also plays a guiding role. The cut rubber material is used for the rotation of the front roller 2, contacts with the blade 8 on the stripping knife 4, moves along the edge of the blade 8, and is stripped from the front roller 2.

[0015] like Figure 1 , Figure 2 As shown, the stripping assembly also includes a demoulding roller 7, which is connected to the connecting frame 5 for relative rotation. By adding the demoulding roller 7, the stability of the rubber material during discharge is higher. The rotation of the demoulding roller 7 can drive the rubber material in contact with the front roller 2 to be stripped, making the product more stable.

[0016] like Figure 1 , Figure 2As shown, the rotation direction of the demoulding roller 7 is opposite to that of the front roller 2, and the rotation speed of the demoulding roller 7 is greater than or equal to that of the front roller 2. The rotation direction of the demoulding roller 7 is opposite to that of the front roller 2, so that the rubber material is transported and peeled in the horizontal direction, and is dragged to prevent the rubber material from falling and accumulating on the machine. The rotation speed of the demoulding roller 7 is equal to that of the front roller 2, so as to avoid the rubber material being unable to be driven and peeled due to too slow speed, and also to avoid the thickness of the rubber material being affected due to too fast speed.

[0017] like Figure 1 , Figure 2 As shown, the blade 8 arranged on the stripping knife 4 is a composite blade. Since the front roller 2 is relatively long, when the blade 8 on the stripping knife 4 cuts and strips the rubber material on the front roller 2, deformation of the blade body is avoided, and the blade 8 is set as a composite blade with multiple blades.

[0018] When the product is in use, when the front roller 2 and the rear roller 3 of the mixing mill are started, the rubber material is pre-mixed, fed, dispersed and mixed before discharging. At this time, the stripping assembly slidably connected to the frame 1 is controlled to slide close to the roller surface of the front roller 2, and the blade 8 of the stripping knife 4 abuts against the roller surface of the front roller 2, cutting the rubber material wrapped on the front roller 2 so that the rubber material is cut off and stripped along the edge of the blade 8, and is bent downward due to gravity and contacts with the rotating demoulding roller 7. At this time, the demoulding roller 7 drives the rubber material to be stripped from the front roller 2 for discharging through its own rotation, and the discharging is carried out in an orderly manner. The distance between the demoulding roller 7 and the front roller 2 is closer than that of the existing belt during discharging, and the stripping of the rubber material is less likely to cause breakage. When the rubber material is still sticky to the front roller 2, the stripping knife 4 located above the demoulding roller 7 and abutting against the roller surface of the front roller 2 plays a stripping role, thereby enhancing the fault tolerance of the product, being quick and simple to use, and enabling the rubber material to be well separated from the front roller 2 to avoid the occurrence of sticking to the roller.
