Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber processing technology, and in particular to a rubber processing mixing tool. Background Technology
[0002] Rubber compounding is a process of mixing raw rubber or plasticized raw rubber with compounding agents to form a compound. This process involves many equipment steps, such as internal mixers, open mills, cutting, and cooling.
[0003] In traditional open mills, the control box is operated to rotate the two rollers during rubber processing. The rubber, which has been processed by an internal mixer, is then placed between the rollers. The rubber is squeezed and stretched through the contact friction between the rollers. During this squeezing and stretching process, the operator uses a blade to cut the rubber multiple times, and then folds and flips it to repeatedly squeeze and stretch it, thus improving the refining effect. However, in actual use, it has been found that when using the blade to cut the rubber, it can scratch the roller surface, causing damage to the rollers. Furthermore, improper operation can cause the blade to be lost and mixed into the rubber, affecting the rubber compounding process and the normal operation of the open mill. Utility Model Content
[0004] The technical problem this invention aims to solve is that when cutting rubber with a blade, the blade may scratch the surface of the roller, causing damage to the roller. Furthermore, improper operation may result in the loss of the blade, which may mix into the rubber, affecting the rubber compounding process and the normal operation of the open mill.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a rubber processing mixing tooling, including a two-roll mill, a control box fixedly connected to the surface of the two-roll mill, two rollers arranged on one side surface of the two-roll mill, and an auxiliary cutting device arranged on the surface of the two-roll mill, the auxiliary cutting device cutting the processed rubber on the rollers.
[0006] The effect achieved by the above components is as follows: when processing rubber, the control box on the open mill is first operated to make the two rollers rotate, and then the rubber processed by the internal mixer is placed between the two rollers. Through the contact friction of the two rollers, the rubber is squeezed and stretched. During this process, the auxiliary cutting device is activated to cut and fold the rubber for continuous processing.
[0007] Preferably, the auxiliary cutting device includes a screw, which is rotatably connected to the inner wall of the open mill. Opposite threads are formed on the arc surfaces at both ends of the screw. A slider is threaded onto each arc surface at both ends of the screw. A cutting block is fixedly connected to one side surface of each slider. A servo motor is fixedly connected to the inner wall of the open mill. Gears are fixedly connected to the output end of the servo motor and the arc surface of the screw, and the two gears mesh with each other. A limit plate is fixedly connected to one side surface of the slider. A slide rail is fixedly connected to the surface of the open mill, and the limit plate is slidably connected to the inner wall of the slide rail.
[0008] The effects achieved by the above components are as follows: when the open mill is processing and mixing rubber, it can cut and split the rubber more efficiently and safely, and it is less likely to cause the blades to scratch the surface of the rollers or cause the blades to get into the rubber, affecting the normal processing of the rubber. It also further improves the use effect and working efficiency of the open mill.
[0009] Preferably, a stabilizing ring is fixedly connected to one side surface of the open mill, and the inner wall of the stabilizing ring is in rolling connection with the arc surface of the gear.
[0010] The effect achieved by the above components is that, by setting up the stabilizing ring, the gears on the servo motor and the screw mesh more stably, making it less prone to misalignment and abnormality, thereby enabling the auxiliary cutting device to be used more stably and normally.
[0011] Preferably, bearings are fixedly connected to both ends of the screw, the inner ring of the bearing is fixedly connected to the arc surface of the screw, and the outer ring of the bearing is fixedly connected to the surface of the open mill.
[0012] The effect achieved by the above components is that, by setting the bearings, the damage caused by rotational friction between the screw and the open mill is reduced, thereby ensuring that the normal rotation of the screw can better drive the cutting block to cut the rubber on the roller.
[0013] Preferably, protective sleeves are fixedly connected to both sides of the surface of the slider. The protective sleeves are sponge sleeves and are fitted onto the arc surface of the screw.
[0014] The effect achieved by the above-mentioned components is that, by setting up the protective sleeve, when the slider slides on the screw, the impurities and debris attached to the screw can be wiped off by the sliding of the protective sleeve, thus ensuring the normal use of the auxiliary cutting device.
[0015] Preferably, a safety device is provided on the surface of the open mill located on the surface of the control box. The safety device includes a rotating shaft, which is fixedly connected to the surface of the open mill. A mounting block is rotatably connected to the arc surface of the rotating shaft, and a protective plate is fixedly connected to one side surface of the mounting block.
[0016] The effect achieved by the above components is that when the open mill is processing rubber, it is less likely that the operator will accidentally touch the buttons on the control box, which could lead to abnormal operation of the open mill and rollers and cause safety accidents, thus ensuring the normal operation of the open mill.
[0017] Preferably, a locking block is fixedly connected to one side surface of the protective plate, and a fixing frame is fixedly connected to one side surface of the open mill, with the locking block engaging with the inner wall of the fixing frame.
[0018] The effect achieved by the above components is that, through the snap-fit design of the locking block and the fixing frame, the protective plate can be more stably covered on the surface of the control box, making it less prone to abnormal shaking and displacement, thus improving the effectiveness of the safety device.
[0019] Preferably, a handle is fixedly connected to one side surface of the protective plate, and the surface of the handle is provided with several anti-slip protrusions.
[0020] The effect achieved by the above components is that the handle makes it easier and faster to flip the protective plate, thus making it easier to use and protect the control box.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] Figure 1 The rubber processing and mixing fixture shown includes a two-roll mill 1, a control box 2 fixedly connected to the surface of the two-roll mill 1, two rollers 3 arranged on one side surface of the two-roll mill 1, an auxiliary cutting device 4 arranged on the surface of the two-roll mill 1, the auxiliary cutting device 4 cutting the processed rubber on the rollers 3, and a safety device 5 arranged on the surface of the two-roll mill 1 located on the surface of the control box 2.
[0032] Figure 1 , Figure 2 and Figure 3The auxiliary cutting device 4 shown includes a screw 41, which is rotatably connected to the inner wall of the open mill 1. The screw 41 has oppositely oriented threads on its two ends' arc surfaces. Slider blocks 42 are threaded onto the arc surfaces of both ends of the screw 41. A cutting block 43 is fixedly connected to one side surface of the slider 42. A servo motor 46 is fixedly connected to the inner wall of the open mill 1. Gears 47 are fixedly connected to the output end of the servo motor 46 and the arc surface of the screw 41, and the two gears 47 mesh with each other. A limit plate 44 is fixedly connected to one side surface of the slider 42. A slide rail 45 is fixedly connected to the surface of the open mill 1, and the limit plate 44 is slidably connected to the inner wall of the slide rail 45. When processing rubber, the control box 2 on the open mill 1 is first operated to rotate the two rollers 3. Then, the rubber processed by the internal mixer is placed between the two rollers 3, and the cutting is achieved through the connection of the two rollers 3. The rubber is squeezed and stretched by friction, and during this process, the servo motor 46 on one side of the open mill 1 is activated, causing the output end of the servo motor 46 to run. Because the gear 47 on the screw 41 meshes with the gear 47 on the servo motor 46, the screw 41 will rotate. Due to the sliding limiting effect of the limiting plate 44 and the slide rail 45, the sliders 42 on both ends of the screw 41 will move closer or further apart, thereby driving the two cutting blocks 43 to cut the rubber wrapped around the roller 3. Then the rubber is shielded and subjected to repeated extrusion and continuous processing. At this time, when the open mill 1 is processing and mixing the rubber, it can cut and split the rubber more efficiently and safely, and it is less likely to cause the blade to scratch the surface of the roller 3 or cause the blade to get into the rubber, affecting the normal processing of the rubber. This further improves the use effect and working efficiency of the open mill 1.
[0033] Figure 1 , Figure 2 and Figure 3 A stabilizing ring 48 is fixedly connected to one side surface of the open mill 1 shown. The inner wall of the stabilizing ring 48 is rolled to the arc surface of the gear 47. By setting the stabilizing ring 48, the meshing of the servo motor 46 and the gear 47 on the screw 41 is more stable and less prone to misalignment, so that the auxiliary cutting device 4 can be used more stably and normally.
[0034] Figure 1 , Figure 2 and Figure 3 The screw 41 shown is fixedly connected to bearings 410 at both ends. The inner ring of the bearing 410 is fixedly connected to the arc surface of the screw 41, and the outer ring of the bearing 410 is fixedly connected to the surface of the open mill 1. By setting the bearings 410, the damage caused by rotational friction between the screw 41 and the open mill 1 is reduced, thereby ensuring that the normal rotation of the screw 41 can better drive the cutting block 43 to cut the rubber on the roller 3.
[0035] Figure 1 , Figure 2 and Figure 3 Protective sleeves 49 are fixedly connected to both sides of the surface of the slider 42 shown. The protective sleeves 49 are made of sponge and are fitted onto the arc surface of the screw 41. By setting the protective sleeves 49, when the slider 42 slides on the screw 41, the impurities and debris attached to the screw 41 can be wiped off by the sliding of the protective sleeves 49, thus ensuring the normal use of the auxiliary cutting device 4.
[0036] Figure 1 and Figure 4 The safety device 5 shown includes a rotating shaft 51, which is fixedly connected to the surface of the open mill 1. A mounting block 52 is rotatably connected to the arc surface of the rotating shaft 51, and a protective plate 53 is fixedly connected to one side surface of the mounting block 52. After the open mill 1 is adjusted and set through the operation control box 2, the protective plate 53 is rotated, causing the mounting block 52 fixedly connected to the protective plate 53 to rotate on the arc surface of the rotating shaft 51 fixedly connected to the surface of the open mill 1 until the protective plate 53 rotates to the position that covers the surface of the control box 2. At this time, when the open mill 1 is processing rubber, it is not easy for the operator to accidentally touch the button on the control box 2, which would cause abnormal operation of the open mill 1 and the roller 3 and lead to a safety accident, thus ensuring the normal operation of the open mill 1.
[0037] Figure 1 and Figure 4 A locking block 54 is fixedly connected to one side surface of the protective plate 53 shown, and a fixing frame 55 is fixedly connected to one side surface of the open mill 1. The locking block 54 is engaged with the inner wall of the fixing frame 55. Through the engagement of the locking block 54 and the fixing frame 55, the protective plate 53 can more stably cover the surface of the control box 2, and it is not easy to cause abnormal shaking or displacement, thus improving the effectiveness of the safety device 5. A handle 56 is fixedly connected to one side surface of the protective plate 53. The surface of the handle 56 is provided with several anti-slip protrusions. Through the setting of the handle 56, the protective plate 53 can be flipped more conveniently and quickly, thereby making it easier to use and protect the control box 2.
[0038] Working principle: When processing rubber, the control box 2 on the open mill 1 is first operated to rotate the two rollers 3. Then, the rubber processed by the internal mixer is placed between the two rollers 3. Through the contact friction of the two rollers 3, the rubber is squeezed and stretched. During this process, the servo motor 46 on one side of the open mill 1 is started, causing the output end of the servo motor 46 to run. Because the gear 47 on the screw 41 meshes with the gear 47 on the servo motor 46, the screw 41 will rotate. And because the limit plate 44 and the slide rail 45... The sliding limit effect allows the sliders 42 at both ends of the screw 41 to move closer or further apart, thereby driving the two cutting blocks 43 to cut the rubber wrapped around the roller 3. Then, the rubber is shielded and subjected to repeated extrusion and continuous processing. At this time, when the open mill 1 is processing and mixing the rubber, it can cut and split the rubber more efficiently and safely, and it is less likely to cause the blade to scratch the surface of the roller 3 or cause the blade to get into the rubber, affecting the normal processing of the rubber. This further improves the use effect and working efficiency of the open mill 1.
[0039] After the open mill 1 is debugged and set through the control box 2, the protective plate 53 is rotated so that the mounting block 52 fixedly connected to the protective plate 53 rotates on the arc surface of the rotating shaft 51 fixedly connected to the surface of the open mill 1 until the protective plate 53 rotates to the position that covers the surface of the control box 2. At this time, the locking block 54 fixedly connected to the protective plate 53 is locked in the inner wall of the fixing frame 55 on the surface of the open mill 1. At this time, when the open mill 1 is processing rubber, it is not easy for the staff to accidentally touch the buttons on the control box 2, which would cause abnormal operation of the open mill 1 and the roller 3 and lead to safety accidents, thus ensuring the normal operation of the open mill 1.
[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
