Description

Technical Field

[0001] The invention relates to the technical field of rubber processing equipment, and in particular to a rubber mixing mill for producing rubber bearings. Background Art

[0002] In the production process of rubber bearings, the rubber mixing mill plays a vital role. It is mainly responsible for the initial processing of rubber raw materials such as plasticizing and mixing, and provides qualified rubber materials for subsequent molding processes. However, the traditional rubber mixing mill has many disadvantages in the feeding process.

[0003] In the past, most rubber mixing mills used manual unloading. Operators needed to hold tools such as knives and get close to the high-speed rotating mixing rollers to cut and peel the materials. On the one hand, the mixing rollers usually run continuously at a high speed, and their strong rotational kinetic energy creates a potential danger zone for the surrounding area. If the operator is not careful, his limbs can easily be caught between the rollers, causing serious personal injury accidents, such as fractures, limb lacerations, etc., which pose a huge threat to the life and health of the operator.

[0004] On the other hand, manual unloading is limited by the operator's physical strength, energy and proficiency. Long-term repetitive work can easily make the operator tired, which in turn leads to more operating errors. When cutting the material, it is difficult to ensure that the cutting position is accurate and consistent each time, and the material cuts are often uneven, which not only causes waste of rubber materials and increases production costs, but also affects the quality stability of subsequent rubber bearing production. Summary of the invention

The convex shaft has a convex portion. After the convex shaft rotates, the convex portion synchronously abuts against a side of the cross-cutting knife close to the first tool holder and a side of the second tool holder close to the mounting frame, thereby driving the cross-cutting knife and the second tool holder to swing synchronously.

[0011] Optionally, the receiving roller comprises: A rotating roller, the rotating roller is rotatably arranged on the mounting plate, and the rotating roller has a plurality of through grooves; An expansion plate, the expansion plate is located in the through groove and is slidably arranged relative to the rotating roller; After the expansion plates slide away from the rotating rollers, the peeled materials are rolled up on the expansion plates, and an expansion space is formed between the materials and the rotating rollers; After the expansion plate is contracted, the expansion plate is released from contact with the material.

[0018] The advantage is that the material can be automatically cut and peeled off through the unloading device, changing the inefficient and high-risk situation of traditional manual operation. The operator does not need to approach the high-speed rotating rubber mixing roller to perform dangerous unloading actions, which greatly ensures personal safety. At the same time, the automated operation makes the unloading process more accurate and stable, effectively avoiding the problems of material waste and uneven cutting caused by manual operation, and improving production efficiency.

[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, proposes a rubber mixing mill for rubber bearing production, including a frame 1; a rubber mixing roller 2 is rotatably arranged in the frame 1, and the rubber mixing roller 2 used in pairs is used to extrude materials; a feeding device 3 includes: a first knife frame 31 is slidably arranged relative to the rubber mixing roller 2, and is located above the rubber mixing roller 2; a cross-cutting knife 32 is swingably arranged on the first knife frame 31, and after the cross-cutting knife 32 swings, it abuts or releases the abutment with the material attached to the rubber mixing roller 2, and after the first knife frame 31 slides, it moves from one side of the rubber mixing roller 2 to the other side, which is used to cut the material horizontally; a scraper 33 is swingably arranged relative to the rubber mixing roller 2, and is located above one side of the rubber mixing roller 2. After the scraper 33 swings, it abuts against the material, and is used to peel the material from the rubber mixing roller 2.

[0026] In this embodiment, in order to solve the problem of high risk of rubber mill unloading in the related art, a rubber mill for rubber bearing production is designed. The frame 1 is welded by solid channel steel. In the frame 1, a pair of rubber mixing rollers 2 rotate to ensure that the parallelism between the two rollers is extremely high, and a uniform and stable processing environment can be provided for the material. The first knife holder 31 of the unloading device 3 slides relative to the rubber mixing roller 2. The cross-cutting knife 32 is installed at the front end of the first knife holder 31, swinging with the pin as the axis, and the blade part is made of special hard alloy, which can easily cut various types of rubber materials. When the material completes the predetermined processing flow on the rubber mixing roller 2, such as after sufficient plasticizing and mixing stages, the unloading program is started by the control system, and the driving device pushes the first knife holder 31 to move slowly and steadily from one side of the rubber mixing roller 2 to the other side. In this process, the cross-cutting knife 32 swings in time, accurately contacts the material attached to the rubber mixing roller 2, and instantly cuts the material horizontally with the sharp blade.

[0027] The scraper 33 is located above one side of the rubber mixing roller 2 and can swing relative to the rubber mixing roller 2. The scraper 33 is made of polytetrafluoroethylene, which has an extremely low friction coefficient. The rubber material is not easy to adhere to it, ensuring the high efficiency of the material stripping process. When the material is cut by the cross-cutting knife 32, the scraper 33 swings quickly, closely fits the surface of the material, and uses its own mechanical structure and material characteristics to smoothly strip the material from the rubber mixing roller 2, preparing for the subsequent material collection process.

[0028] The advantage is that the material can be automatically cut and peeled off by the material unloading device 3, which changes the inefficiency and high risk of traditional manual operation. The operator does not need to approach the high-speed rotating rubber mixing roller 2 to perform dangerous unloading actions, which greatly guarantees personal safety. At the same time, the automated operation makes the unloading process more accurate and stable, effectively avoiding the problems of material waste and uneven cutting caused by manual operation, and improving production efficiency.

[0029] Furthermore, it also includes a mounting plate 34, which is swingably set on the side wall of the frame 1 near one end of the cross-cutting knife 32; a receiving roller 35 is rotatably set on the mounting plate 34, and the receiving roller 35 is used to roll up the peeled material after rotation; a material picking table 36 is slidably set relative to the receiving roller 35; after the mounting plate 34 is rotated, the receiving roller 35 is close to the material picking table 36, and the material picking table 36 is used to support the material rolled up on the receiving roller 35.

[0030] In this embodiment, the mounting plate 34 is mounted on the side wall of the frame 1 near one end of the cross-cutting knife 32 through a hinge. The receiving roller 35 is rotatably mounted on the mounting plate 34 through a high-precision bearing. The surface of the receiving roller 35 is specially textured to increase the friction between the material and the material, ensuring that the stripped material can be tightly wound on it. The material collection platform 36 is relatively slidably arranged with the receiving roller 35 through a slide rail structure. After the scraper 33 strips the material from the rubber mixing roller 2, the material moves toward the receiving roller 35 under its own gravity and the guiding action of the scraper 33, and the material collection is completed. The mounting plate 34 rotates under the drive of the electric push rod, so that the receiving roller 35 is close to the receiving platform 36. The receiving platform 36 slides along the slide rail close to the receiving roller 35, and the operator can easily remove the material rolled on the receiving roller 35. The whole process is convenient and efficient. The advantage is that this design optimizes the material collection process and further improves the degree of automation of production.

[0031] Furthermore, it also includes a screw rod 4, which is rotatably arranged in the frame body 1; a guide rod 5 is arranged in the frame body 1; one end of the first tool holder 31 is threadedly connected to the screw rod 4, and the other end is slidably arranged on the guide rod 5.

[0032] In this embodiment, both ends of the screw rod 4 are fixed in the frame 1 through bearing seats to ensure that there is no shaking or displacement during high-speed rotation. The screw rod 4 is arranged parallel to the frame 1, and the guide rod 5 is parallel to the screw rod 4 to provide guidance for the first tool holder 31. The threaded hole at one end of the first tool holder 31 is precisely matched with the screw rod 4, and the other end is sleeved on the guide rod 5, forming a stable and reliable sliding connection structure.

[0033] When it is necessary to drive the first tool holder 31 to move, the servo motor drives the screw rod 4 to rotate. According to the forward and reverse rotation and speed control of the motor, the first tool holder 31 can move quickly and accurately from one end of the rubber mixing roller 2 to the other end at a stable speed along a predetermined trajectory under the coordinated action of the screw rod 4 and the guide rod 5, ensuring that the cross-cutting knife 32 can cut the material at the best position every time, greatly improving the accuracy and efficiency of material unloading.

[0034] The advantage is that, compared with a simple linear drive method, the combination of the screw rod 4 and the guide rod 5 provides a stable motion trajectory for the first knife holder 31. This makes the cutting position of the cross-cutting knife 32 more accurate. At the same time, the stable structure reduces the failure rate of the equipment, reduces the equipment maintenance cost, and prolongs the service life of the equipment.

[0035] Furthermore, the unloading device 3 has two sets, the screw rod 4 has a first thread 41 and a second thread 42, the first thread 41 and the second thread 42 rotate in opposite directions, the two first tool holders 31 are threadedly connected with the first thread 41 and the second thread 42 respectively, after the screw rod 4 rotates, the two first tool holders 31 approach or move away from each other, and also includes a mounting frame 6, the mounting frame 6 is located between the two first tool holders 31, one end of the mounting frame 6 has a through hole 61, the other end of the mounting frame 6 is arranged on the guide rod 5, and the screw rod 4 rotates in the through hole 61; one end of the second tool holder 7 is swingably arranged on the mounting frame 6, and the scraper 33 is arranged on the second tool holder 7; the longitudinal cutting knife 8 is arranged at the other end of the second tool holder 7, after the second tool holder 7 swings, the longitudinal cutting knife 8 is used to longitudinally cut the material attached to the rubber mixing roller 2.

[0036] In this embodiment, the unloading device 3 is equipped with two sets of unloading units symmetrically distributed on both sides of the rubber mixing roller 2. The screw rod 4 is specially processed and has a first thread 41 and a second thread 42 with opposite rotation directions. The two first tool holders 31 are tightly engaged with the corresponding threads. The mounting frame 6 is located between the two first tool holders 31. The through hole 61 at one end of the mounting frame 6 is sleeved on the outside of the screw rod 4 to ensure that the screw rod 4 will not affect the mounting frame 6 during the rotation process. The other end of the mounting frame 6 is firmly set on the guide rod 5 to make its overall structure stable.

[0037] One end of the second tool holder 7 is swingably set on the mounting frame 6 through a pin shaft, and the scraper 33 is fixed on the second tool holder 7. The longitudinal cutter 8 is vertically installed at the end of the short arm. The longitudinal cutter 8 is made of the same quality hard alloy as the cross-cutting knife 32, which is sharp and durable. When the screw rod 4 rotates, the two first tool holders 31 approach or move away from each other according to the direction of rotation of the thread. The longitudinal cutter 8 falls, dividing the material attached to the rubber mixing roller 2 into left and right parts. At the same time, the cross-cutting knife falls, cutting the material horizontally, realizing the reduction of the volume of the material, and dividing it into left and right parts.

[0038] The advantage is that the two sets of unloading devices 3 work together, greatly improving the efficiency of unloading, and can meet the rapid unloading requirements of large-scale rubber bearing production. The addition of the longitudinal cutting knife 8 realizes the left and right area processing of the material, making the material more regular and orderly when winding, ensuring the smooth progress of the subsequent rubber bearing molding process, thereby significantly improving the overall production efficiency.

[0039] Furthermore, the connection between the first tool holder 31 and the cross-cutting knife 32, and the mounting frame 6 and the second tool holder 7 are all provided with torsion springs, and also include a cam 9, which is rotatably arranged in the frame body 1, and is located between the first tool holder 31 and the cross-cutting knife 32 and the mounting frame 6 and the second tool holder 7. The cam 9 has a convex portion 91. After the cam 9 rotates, the convex portion 91 synchronously abuts against the side of the cross-cutting knife 32 close to the first tool holder 31 and the side of the second tool holder 7 close to the mounting frame 6, thereby driving the cross-cutting knife 32 and the second tool holder 7 to swing synchronously.

[0040] In this embodiment, both ends of the convex shaft 9 are rotatably arranged in the frame 1 through bearings, and are located between the first tool holder 31 and the cross-cutting knife 32, and the mounting frame 6 and the second tool holder 7. It is ensured that the convex portion 91 of the convex shaft 9 can smoothly transmit power. Torsion springs with appropriate torsion force are installed at the connection between the first tool holder 31 and the cross-cutting knife 32, and the mounting frame 6 and the second tool holder 7. The torsion springs provide initial pre-tightening force for these components, so that they maintain a specific position under normal conditions.

[0041] When unloading operation is required, the driving motor drives the cam shaft 9 to rotate, and the convex part 91 of the cam shaft 9 synchronously abuts against the side of the cross-cutting knife 32 close to the first knife holder 31 and the side of the second knife holder 7 close to the mounting frame 6, overcoming the elastic force of the torsion spring, driving the cross-cutting knife 32 and the second knife holder 7 to swing synchronously, achieving a high degree of coordination and unity between the rapid cutting and stripping actions of the materials.

[0042] The advantage is that, through the exquisite cooperation between the cam shaft 9 and the torsion spring, only one driving action is needed to realize the synchronous control of the cross-cutting knife 32 and the second knife holder 7, which greatly simplifies the operation process and improves the automation degree of the equipment. The synchronous operation ensures the precise matching of the material cutting and stripping timing, effectively avoids the problems of material tearing and residue caused by uncoordinated actions, improves the quality of material feeding, and further improves the stability and reliability of rubber bearing production.

[0043] Furthermore, the material receiving roller 35 includes a rotating roller 351, which is rotatably set on the mounting plate 34, and has a plurality of through grooves 3511; the expansion plate 352 is located in the through grooves 3511, and is slidably set relative to the rotating roller 351; after the expansion plate 352 slides away from the rotating roller 351, the peeled material is rolled up on the plurality of expansion plates 352, and an expansion space is formed between the inner wall of the material and the rotating roller 351; after the expansion plate 352 contracts, the expansion plate 352 is released from the abutment with the inner wall of the material.

[0044] In this embodiment, one end of the rotating roller 351 of the receiving roller 35 is mounted on the mounting plate 34 through a bearing. A plurality of through grooves 3511 are evenly distributed on the rotating roller 351, and these through grooves 3511 provide space for the movement of the expansion plate 352.

[0045] After the scraper 33 peels off the material, the material approaches the receiving roller 35 under its own gravity and guiding action, and the expansion plate 352 slides outward along the through groove 3511. The material is rolled up on a plurality of expansion plates 352, and an expansion space is formed between the inner wall of the material and the rotating roller 351. When the material needs to be removed, the expansion plate 352 is contracted and enters the through groove 3511, so that the expansion plate 352 is released from the contact with the inner wall of the material. With the support of the material taking platform 36, the material will not come into contact with the receiving roller when it slides away from the receiving roller 35, thereby no friction is generated and the shape of the rolled material will not be damaged when the material is unloaded.

[0046] Furthermore, the rotating roller 351 has a cavity 3512 inside, and the through slot 3511 is connected to the cavity 3512. The receiving roller 35 also includes a sliding rod 353, which is slidably set in the cavity 3512; one end of the first scissors rod 354 is hinged on the rotating roller 351, and the other end extends out of the through slot 3511; one end of the second scissors rod 355 is hinged on the sliding rod 353, and the other end extends out of the through slot 3511; the expansion plate 352 has a slide groove 3521, the other end of the first scissors rod 354 is slidably set in the slide groove 3521, and the other end of the second scissors rod 355 is hinged on the expansion plate 352. After the sliding rod 353 slides in the cavity 3512, several expansion plates 352 synchronously approach or move away from the rotating roller 351.

[0047] In this embodiment, when the position of the expansion plate 352 needs to be adjusted, the push drive member drives the sliding rod 353 to slide in the cavity 3512. Through the mechanical linkage of the scissor rod structure, several expansion plates 352 synchronously approach or move away from the rotating roller 351, thereby accurately controlling the size of the winding space.

[0048] The advantage is that the clever use of the scissor-bar structure enables precise synchronous control of the expansion plate 352, and compared with a simple elastic expansion structure, this design can more accurately adjust the winding space.

[0049] Furthermore, it also includes an elastic film 10 , which is sleeved on the outside of a plurality of expansion plates 352 , and the expansion plates 352 are in contact with the material through the elastic film 10 .

[0050] In this embodiment, the elastic film 10 is made of a highly elastic and wear-resistant rubber material and is sleeved on the outside of the plurality of expansion plates 352. During the material winding process, the elastic film 10 closely fits the material and fills the gaps between the expansion plates 352 with its own elasticity, effectively preventing the material from being partially loosened during the winding process and entering the gaps between the expansion plates 352.

[0051] The advantage is that the addition of the elastic film 10 further optimizes the material collection effect, enhances the fit between the material and the expansion plate 352, provides higher quality raw materials for subsequent rubber bearing molding processing, reduces the probability of product defects, improves product qualification rate, and ensures the quality of the rubber bearing.

[0052] Furthermore, it also includes a guide plate 11, which is slidably set on the frame 1 and is located below the receiving roller 35. After the guide plate 11 approaches the receiving roller 35, a guide space is formed between it and the receiving roller 35, and the guide space is used to guide the peeled material to be wound around the receiving roller 35.

[0053] In this embodiment, the guide plate 11 is made of a stainless steel sheet. When the material is peeled off, the external driving device drives the guide plate 11 to quickly approach the receiving roller 35, and a guide space is formed between the guide plate 11 and the receiving roller 35. The peeled material is accurately wound on the receiving roller 35 by utilizing the inclined angle and smooth surface of the guide plate 11, avoiding the risk of winding chaos caused by irregular movement of the material during the initial winding.

[0054] The advantage is that the guide plate 11 provides a clear path guide for the material winding, reduces the risk of material winding disorder caused by disordered movement in the early stage of winding, and improves the neatness of winding. It reduces the time and labor intensity of manual material sorting, improves production efficiency, ensures the orderly production of rubber bearings, and makes the entire production process smoother. Furthermore, the scraper 33 has a guide slope 331, which is used to guide the material to abut against the receiving roller 35 after abutting against the material.

[0055] In this embodiment, the guide inclined surface 331 of the scraper 33 is located at the front end of the scraper 33, and is finely polished, with a smooth surface and a suitable inclination angle, generally between 30° and 45°. When the scraper 33 swings to peel the material from the rubber mixing roller 2, the material slides down along the guide inclined surface 331. Due to the guiding effect of the inclined surface, the material can smoothly abut against the receiving roller 35, realizing a smooth transition of the material from peeling to winding.

[0056] The rotating drive member 12 uses an efficient servo motor. The motor output shaft is meshed with the gear ring 3513 that penetrates the mounting plate 34 at one end of the rotating roller 351, and can stably output strong torque to drive the rotating roller 351 to rotate at a uniform speed, ensuring that the material winding process is smooth and orderly without jamming or sudden speed changes.

[0057] The sliding drive member 13 adopts a high-precision electric cylinder, and a special sleeve ring on the head of the cylinder piston rod is accurately sleeved on the outside of the ring groove 3531. The displacement of the sliding rod 353 is accurately controlled by the extension and contraction of the electric control cylinder to meet the adjustment requirements of the expansion plate 352.
