Description

Technical Field

[0001] The present invention relates to the technical field of tire production equipment, and particularly relates to a device for efficiently and continuously on-line laminating small rubber sheets on the apex rubber Background Art

[0002] In the production of tire semi-finished products, a small rubber sheet needs to be laminated on the soft rubber of the apex rubber; it is used to protect the friction between the steel wire and the apex rubber after the steel cord carcass is turned back, so as to ensure the stability of the apex rubber during use. The laminating accuracy and quality of this small rubber sheet have a great influence on the forming quality of the tire.

[0003] The existing method for laminating small rubber sheets on the apex rubber mainly adopts off-line lamination, that is, the small rubber sheets are first produced in a rolled-up form; then the rolled-up small rubber sheets are exported on the apex rubber production line and laminated on the soft rubber surface of the apex rubber to complete the lamination of the small rubber sheets on the apex rubber.

[0004] For example, Chinese Patent No. CN201552759U discloses a laminating device for the apex rubber sheet of all-steel tires, which includes a frame, a guide plate, a nylon pressing roller, an adjusting screw rod, a sponge pressing roller, and a cylinder; on the upper end of the frame, there are two groups of rubber sheet stations on the left and right, namely the upper rubber sheet station and the lower rubber sheet station; a guide plate is provided directly below each group of rubber sheet stations, and a nylon pressing roller is provided thereon; a cylinder is provided in the middle of the frame, and a sponge pressing roller is provided on the left and right on the connecting rod connected to the cylinder below the cylinder, and an adjusting screw rod is provided in the middle directly below the cylinder and between the two sponge pressing rollers.

[0005] This kind of apex rubber sheet laminating device is off-line lamination. Although it has a simple structure and is easy to produce, on the one hand, off-line lamination must use small rubber sheet rolls. After the small rubber sheets are rolled up, they have cooled to room temperature. Therefore, when laminating the cooled rubber sheets, air bubbles are likely to be generated, resulting in a poor laminating effect; in addition, after each roll of small rubber sheets is used up, a new roll of material needs to be lapped. This is not only time-consuming and affects production efficiency, but also requires manual lapping of the rubber sheet joints, and the accuracy and quality of manual lapping are uncontrollable. Summary of the Invention

[0006] In view of the above technical problems, the present invention overcomes the shortcomings of the prior art and provides a device for efficiently and continuously on-line laminating small rubber sheets on the apex rubber.

[0007] To solve the above technical problems, the present invention provides a device for efficiently and continuously on-line laminating small rubber sheets on the apex rubber.

[0008] Technical effect: The small film is continuously fed by an extruder, replacing the method of feeding with coiled materials. The required small film is extruded by a two-roll calender. Therefore, the provided small film is a hot film; when the hot film is bonded to the apex strip surface, the bonding effect is better, air bubbles are not easily generated, and the bonding is tight; at the same time, the extruder continuously feeds materials, enabling continuous bonding, avoiding manual lapping, improving the accuracy and stability of bonding, and reducing the impact of manual lapping on product quality.

[0009] A further limited technical solution of the present invention is: An efficient continuous online bonding device for small films and apex strips, including a frame. A conveying assembly for conveying apex strips is horizontally arranged on the frame. One side of the conveying assembly is the feeding end of the apex strip and the small film, and the other side is the discharging end of the bonded product of the apex strip and the small film. It is characterized in that: outside the frame

[0010] There is a calendering device, located on one side of the frame near the feeding end. It includes calendering rollers, which are used to calender the extruded rubber material into a large film with a certain thickness. The blades on the calendering rollers cut the large film and output two small films and convey the small films to the apex strip on the conveying assembly.

[0011] The extruder is located outside the frame and is used to stir various raw materials according to proportional formulas and extrude the rubber material. A rubber material conveying channel is arranged between the discharging port position of the extruder and the feeding port of the calendering device, which is used to lift and convey the extruded rubber material into the calendering device.

[0012] A bonding assembly is arranged on the frame, including a number of thousand-layer rollers distributed in the middle position of the frame. The thousand-layer rollers are close to the conveying assembly and have a gap. The apex strips and small films on both sides of the conveying assembly are respectively tightly attached to each other, pass through the gap, and are tightly bonded by the thousand-layer rollers.

[0013] There is a film bonding position adjusting part on the frame, which is connected to a number of thousand-layer rollers and is used to adjust the height and horizontal position of the thousand-layer rollers. The thousand-layer roller includes a horizontally arranged pressing shaft, and a number of washers with mutually attached end faces are sleeved on the pressing shaft. The washers are in a ring structure, and the outer circular surface of the washers is pressed against the small film and the apex strip.

[0014] Further, an adjusting shaft is arranged outside the thousand-layer roller. The adjusting shaft includes a number of ball bearings with mutually attached end faces. The ball bearings are arranged corresponding to the washers, and the side surfaces of the ball bearings are tightly attached to the side surfaces of the washers, which is used to prevent the washers from being pressed unevenly. Two adjusting shafts are symmetrically arranged with respect to the thousand-layer roller.

[0015] The above-mentioned high-efficiency continuous on-line small film laminating device for apex rubber, the adjusting member includes a plurality of sliding blocks corresponding to the thousand-layer roller and slidably connected to the frame. A adjusting cylinder is fixed on the sliding block and arranged vertically downward perpendicular to the horizontal plane. The end of the output shaft of the adjusting cylinder is connected to the thousand-layer roller, which is used to adjust the height of the thousand-layer roller, so as to realize the pressing state of the thousand-layer roller during operation and the state that it can be lifted when not working, which is convenient for operation;

[0016] On the frame, there is a sliding rod arranged parallel to the horizontal plane. The sliding rod penetrates through the sliding block so that the sliding block can slide along the direction of the sliding rod. On the frame, there is also an adjusting lead screw arranged parallel to the sliding rod. The adjusting lead screw penetrates through a plurality of sliding blocks in sequence and is threadedly connected to them. The adjusting lead screw is driven to rotate by a handwheel arranged at its end, so as to adjust the relative position of the thousand-layer roller to correspond to the position where the apex rubber is laminated with the small film.

[0017] The above-mentioned high-efficiency continuous on-line small film laminating device for apex rubber, there is a guiding member for adjusting the input position and angle of the small film between the calender device and the laminating assembly. The guiding member includes a horizontal guiding roller for adjusting the horizontal direction of the small film and a vertical guiding roller for adjusting the vertical direction of the small film. There are several groups of horizontal guiding rollers corresponding to the thousand-layer roller. Each group of horizontal guiding rollers includes at least four symmetrically arranged in pairs, which are used to correct the position of the small film cut from the calender device so that it matches the position of the apex rubber on the conveying assembly.

[0018] The above-mentioned high-efficiency continuous on-line small film laminating device for apex rubber, the guiding member includes a plurality of guiding seats respectively corresponding to and connected to several groups of horizontal guiding rollers. A guiding rod extending in the horizontal direction is arranged on the frame. The vertical guiding roller is rotatably connected to the frame, and its extending direction is the same as that of the guiding rod;

[0019] The guiding seat is slidably connected to the guiding rod. The horizontal guiding rollers are all perpendicular to the guiding seat and rotatably connected to it. The whole guiding seat is inclined towards the thousand-layer roller side. On the frame, there are several groups of guiding lead screws arranged parallel to the guiding rod corresponding to the guiding seat. The guiding lead screws penetrate through the corresponding guiding seats and are threadedly connected to them, which are used to adjust the positions of the corresponding guiding seats respectively. The guiding lead screws are also driven to rotate by handwheels fixed at their ends.

[0020] The above-mentioned high-efficiency continuous online bonding device for small rubber strips of triangular rubber strips also has a guiding member at the discharge end of the conveying assembly, which is used to convey the finished triangular rubber strips to the next unit. The guiding member at the discharge end also includes a vertical guiding roller, several horizontal guiding rollers and an adjustable guiding seat. On the frame, there is an adjusting rod located outside the discharge end and used to support the bottom surface of the finished triangular rubber strip. The adjusting rod is composed of a shaft rod and several Fuller wheels that are attached end to end and rotatably sleeved on the shaft rod. Each side of the Fuller wheel is rotatably connected with a ball, and the ball is ellipsoidal in shape. It is used to cooperate with the above-mentioned parts to accurately guide two triangular rubber strips onto the conveying assembly (7), ensuring accurate positioning of the triangular rubber strips without wrinkles.

[0021] The above-mentioned high-efficiency continuous online bonding device for small rubber strips of triangular rubber strips. The calendering device includes a machine body. On the top of the machine body, there are two parallel and inclined installation plates fixed. A chute is formed on the installation plate. At the top end position of the chute, there is a fixed block, and a movable block is slidably connected in the chute. A fixed calender roller is rotatably connected between the two fixed blocks, and a movable calender roller is rotatably connected between the two movable blocks. There is a motor reducer on the installation plate, and the motor reducer is connected to the fixed calender roller to drive the fixed calender roller to rotate, pressing the rubber material into a film with a certain width and thickness, and the thickness of the film can be adjusted through the above mechanism to meet the requirements of the bonding process.

[0022] The above-mentioned high-efficiency continuous online bonding device for small rubber strips of triangular rubber strips. At the discharge position of the fixed calender roller on the installation plate, there is a cutting roller. At the bottom of the cutting roller, there are several cutting knives corresponding to the thousand-layer rollers. The position of the cutting knives is adjusted by a cutting lead screw arranged on the machine body. At the top of the cutting roller, there is a guiding roller rotatably connected to the installation plate, which is used to guide the cut small rubber strips to the corresponding position of the bonding assembly.

[0023] The above-mentioned high-efficiency continuous online bonding device for small rubber strips of triangular rubber strips. At the bottom end position of the chute, there is a pressure adjusting member, and the pressure adjusting member is connected to the bottom surface of the movable block through an elastic part, which is used to adjust the pressure between the movable calender roller and the fixed calender roller. At the ends of the movable calender roller and the fixed calender roller, there are respectively a driving gear and a driven gear that mesh with each other. The relative rotation between the movable calender roller and the fixed calender roller is realized through the transmission of the driving gear and the driven gear, and the rubber material is calendered and a film with a certain thickness is input.

[0024] The above-mentioned high-efficiency continuous online bonding device for small rubber strips of triangular rubber strips. The conveying assembly includes conveying rollers rotatably connected to both ends of the frame. A conveyor belt is wound around the conveying rollers, and the top of the conveyor belt is laid on the top surface of the frame, which is used to convey the triangular rubber strips. A conveying motor is fixed at the bottom of the frame, and the conveying motor and the conveying rollers are driven by a conveying sprocket and a chain.

[0025] The beneficial effects of the present invention are:

[0026] (1) In the present invention, the raw materials enter the extruder from the feeding port, are heated into a molten state by the extruder, and then the molten material is lifted to the feeding port of the calendering device through the rubber conveying channel. The calendering device calenders and cuts the material into the required small film shape. The small film is conveyed to the bottom of the laminating assembly on the frame by the calendering device. At this time, the conveying assembly at the bottom of the laminating assembly conveys the triangular rubber formed in the previous unit to the designated position. After the small film is tightly attached to the surface of the triangular rubber, the two can be laminated and fixed through the thousand-layer roller, completing the bonding and fixing of the small film and the triangular rubber. Before the small film enters the conveying assembly, the adjusting member on the frame can adjust the entering position and height of the small film, thereby ensuring the accuracy of the lamination between the small film and the triangular rubber. The feeding and discharging of the present invention are completed by mechanical components, eliminating the need for manual replacement and lapping of the film coils, greatly improving the production efficiency and the precision of the triangular rubber lamination, and enhancing the product quality.

[0027] (2) In the present invention, since the thousand-layer roller is entirely composed of several washer pieces, when pressing, it can tightly attach to the film from the side of the washer piece. Since the washer piece is hollow and annular, at the uneven places of the triangular rubber, the washer piece can adjust its position to a certain extent to avoid squeezing and deforming the triangular rubber, thus ensuring the shape integrity of the triangular rubber while guaranteeing the pressing effect. In addition, the thousand-layer roller is formed by several washer pieces. When pressing triangular rubbers of different sizes and models, the size of the corresponding washer piece can be changed according to different shapes, making the shape of the thousand-layer roller more fitting to the shape of the triangular rubber and expanding the applicable range of the entire device. The setting of the ball bearing can correspond to the side fitting of the washer piece. On the one hand, it can scrape off the residual rubber material on the washer piece, and on the other hand, it can correct the washer piece to ensure the pressing and fitting effect.

[0028] (3) In the present invention, since each time the machine is started, the thickness, entering position, and angle of the triangular rubber and the small film will change to a certain extent, it is necessary to correspondingly adjust the position and height of the thousand-layer roller during production. Through the adjusting cylinder arranged on the sliding block, the entire thousand-layer roller can be driven to lift, thereby adjusting the height of the thousand-layer roller. The sliding rod can ensure the horizontal sliding of the sliding block. By rotating the adjusting screw rod with the handwheel, the sliding block and the thousand-layer roller can be driven to move under the action of the thread to change the position of the thousand-layer roller in the horizontal direction.

[0029] (4) In the present invention, the guiding member is provided to change the entry angle and direction of the small film. The vertical guiding roller can change the vertical direction of the small film entering. Therefore, it can be provided at both ends where the small film enters and exits the frame and at the bottom of the small film entering the laminating assembly. The horizontal guiding roller is provided to change the horizontal direction of the small film entering the laminating assembly. Therefore, several groups need to be provided to guide the small film in sequence to correct its entry orientation and avoid contact with other devices. In addition, by providing a guiding seat and a guiding lead screw, the horizontal orientation of several horizontal guiding rollers can be adjusted as needed, thereby improving the accuracy of guiding the horizontal orientation of the small film.

[0030] (5) In the present invention, after the molten material enters the calendering device, it first passes through the gap between the fixed pressure roller and the moving pressure roller. The rotation of the two pressure rollers can calender the material into a sheet shape. Then it bypasses the cutting roller, and the cutting knife provided at the bottom of the cutting roller can cut the sheet-shaped material into small films of a specified width. The provided cutting lead screw can also adjust the cutting knife, thereby changing the width of the cut small film. In addition, the pressure adjusting member can apply a certain pressure to the moving pressure roller through the elastic part to ensure that there is an appropriate pressure between the moving pressure roller and the fixed pressure roller to calender the small film. By changing the pressure magnitude, the thickness of the small film can be changed. Description of the Drawings

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] A high-efficiency continuous online laminating device for triangular rubber and small film provided in this embodiment has a structure as shown in Figure 1 and Figure 2As shown in the figure, the whole device includes an extruder 4, a calendering device 2 and a laminating assembly 3 connected in sequence. A rubber material conveying channel 41 is arranged between the extruder 4 and the calendering device 2. A conveying assembly 7 is arranged at the bottom of the laminating assembly 3 for conveying materials from the calendering device 2 to the lower part of the laminating assembly 3.

[0045] The operation idea of this equipment is as follows: Put the materials into the extruder 4, heat and melt the materials through the extruder 4 and continuously extrude the materials. The lifting device can continuously send the materials into the calendering device 2. The calendering device 2 calenders and cuts the materials into the shape required for the small film 8. At this time, the conveying assembly 7 conveys the apex rubber 9 completed in the previous unit to the laminating assembly 3. At the same time, the small film 8 continuously adheres tightly to the apex rubber 9. After the two pass through the laminating assembly 3, they are adhered together to complete the continuous lamination of the apex rubber.

[0046] As Figure 2 and Figure 3 As shown in the figure, the main part of this equipment is the position of the laminating assembly 3. The whole includes a frame 1. The right side of the frame 1 is the calendering device 2. The laminating assembly 3 is arranged in the middle of the frame 1. The conveying assembly 7 is horizontally arranged on the frame 1 and conveys the apex rubber 9 from right to left. The calendering device 2 includes a machine body. An installation plate 21 inclined to the left is arranged above the machine body. After the calendering device 2 calenders and cuts the materials into small films 8, it conveys the small films 8 to the bottom of the laminating assembly 3 to the lower left and adheres tightly to the apex rubber 9. After passing through the laminating assembly 3, the lamination is completed.

[0047] As Figures 3 to 5 As shown in the figure, the lower part of the machine body of the calendering device 2 is hollow, which is convenient for the apex rubber 9 to enter the conveying assembly 7 through the bottom space; the installation plate 21 is symmetrically arranged about the center line of the machine body. An inclined chute 22 is opened in the middle position of the installation plate 21. A fixed block 23 is embedded at the top of the chute 22. A movable block 24 is slidably connected in the chute 22 below the fixed block 23. A fixed pressure roller 25 is rotatably connected between the two fixed blocks 23, and a movable pressure roller 26 is rotatably connected between the two movable blocks 24.

[0048] As Figures 3 to 5 As shown in the figure, a motor reducer 27 is fixed on the installation plate 21 on one side of the machine body, and a driving gear 213 and a driven gear 214 are arranged on the other side. The output shaft of the motor reducer 27 is connected to the fixed pressure roller 25 for driving the fixed pressure roller 25 to rotate. The driving gear 213 is coaxially fixed at the end of the fixed pressure roller 25, and the driven gear 214 is coaxially connected at the end of the movable pressure roller 26, and the driving gear 213 meshes with the driven gear 214. After the motor reducer 27 drives the fixed pressure roller 25 to rotate, the driving gear 213 can drive the driven gear 214 engaged with it, so that the movable pressure roller 26 rotates synchronously, and the rotation direction of the movable pressure roller 26 is opposite to that of the fixed pressure roller 25, improving the calendering effect of the materials.

[0049] AsFigures 3 to 5 As shown, a pressure adjusting member 211 is fixed on the bottom wall of the chute 22 below the dynamic pressure roller 26. The pressure adjusting member 211 is connected to the movable block 24 through an elastic portion 212. Here, the elastic portion 212 can be a spring or other elastic components. The pressure adjusting member 211 can apply a thrust to the movable block 24 through the elastic portion 212, so that the pressure between the dynamic pressure roller 26 and the fixed pressure roller 25 changes. Thus, by changing the magnitude of the pressure applied by the pressure adjusting member 211, the thickness of the required small film 8 can be changed.

[0050] As Figures 3 to 5 shown, a cutting roller 28 is also rotatably connected to the front side of the mounting plate 21. The cutting roller 28 is located obliquely below the fixed pressure roller 25. The straight line where the interval between the dynamic pressure roller 26 and the fixed pressure roller 25 is located is tangent to the side surface of the cutting roller 28. Therefore, the small film 8 after calendering is first wound around the cutting roller 28, and a cutting knife 281 is provided below the cutting roller 28. The top of the cutting knife 281 fits against the side surface of the cutting roller 28. Therefore, the cutting knife 281 can cut the semi-finished small film 8 into the finished small film 8 with the required width.

[0051] In addition, the cutting knife 281 is slidably connected to the machine body and is driven to slide by a cutting lead screw 282. The cutting lead screw 282 penetrates through the cutting knife 281 and is threadedly connected thereto. A hand wheel 55 for convenient rotation is also provided at the end of the cutting lead screw 282. In addition to the cutting roller 28 and the cutting knife 281, a guiding roller 29 is also provided at the front position of the fixed pressure roller 25. As Figure 4 shown, the guiding roller 29 is located above the cutting roller 28 and is rotatably connected between the two mounting plates 21. After the small film 8 is cut, the small film 8 enters the guiding roller 29 and enters the next laminating assembly 3 through the guiding roller 29.

[0052] As Figure 6 and Figure 7 shown, after the small film 8 passes through the guiding roller 29, it also needs to pass through the guiding member 6 to adjust its direction and entry angle before it can enter the laminating assembly 3 more precisely. Therefore, the guiding member 6 is provided at the rear position of the laminating assembly 3 on the frame 1, between the laminating assembly 3 and the calendering device 2. The guiding member 6 mainly includes a horizontal guiding roller 61 and a vertical guiding roller 62.

[0053] As Figure 6 and Figure 7 shown, the function of the horizontal guiding roller 61 is to change the entry direction of the small film 8 in the horizontal position. A number of horizontal guiding rollers 61 are provided. In this embodiment, two sets of symmetrically arranged ones are provided, that is, four horizontal guiding rollers 61 in each set, which are used to align the position of the small film 8 cut out from the calendering device 2 with the position of the triangular rubber on the conveyor belt.

[0054] In each set of horizontal guide rollers 61, the two horizontal guide rollers 61 close to the calendering device 2 are perpendicular to the horizontal plane, and the two horizontal guide rollers 61 close to the laminating device are inclined. The horizontal guide rollers 61 are also slidably connected to the frame 1 through guide seats 63.

[0055] As Figure 6 and Figure 7 shown, guide rods 64 spanning across the frame 1 are provided on the frame 1. There are several guide rods 64, and guide seats 63 are slidably arranged on each guide rod 64. In addition, a guide lead screw 65 parallel to the guide rod 64 is also provided on the frame 1. In this embodiment, two guide lead screws 65 are provided, and each guide lead screw 65 penetrates through the corresponding set of horizontal guide rollers 61 and is threadedly connected thereto. Handwheels 55 are correspondingly arranged at the ends of the guide lead screws 65 to facilitate rotating the guide lead screws 65 and adjusting the positions of the corresponding sets of horizontal guide rollers 61.

[0056] The vertical guide rollers 62 are arranged parallel to the guide rods 64. They are provided at the front positions of the two inclined horizontal guide rollers 61 in each set of horizontal guide rollers 61 and can adjust the vertical entry angle of the small film 8. It should be noted that vertical guide rollers 62 are also provided on the frame at the front of the laminating assembly 3, which can further adjust the angle of the small film 8 entering the laminating assembly 3 to ensure the accuracy of lamination.

[0057] As Figure 6 shown, the conveying assembly 7 in this embodiment is a conveyor belt 72, and the conveyor belt 72 is distributed on the upper surface of the entire frame 1. Conveying rollers 71 are provided at both the front and rear ends of the frame 1. The conveyor belt 72 is wound around the conveying rollers 71 and moves under the rotational drive of the conveying rollers 71. A conveying motor 73 is provided at the bottom of the frame 1. The output shaft of the conveying motor 73 and the ends of the conveying rollers 71 are correspondingly fixed with conveying sprockets 74, and a chain 75 is wound between the two conveying sprockets 74. In this way, the conveying motor 73 can drive the conveying rollers 71 and the conveyor belt 72 to rotate synchronously.

[0058] As Figure 6 and Figure 8 shown, the laminating assembly 3 in this embodiment is two parallel thousand-layer rollers 31. The thousand-layer roller 31 includes two parts. One is a horizontally arranged pressing shaft 311, and the other is a number of washer plates 312 sleeved on the pressing shaft 311. A number of washer plates 312 are closely attached to form a tight thousand-layer roller 31. The end faces of the washer plates 312 are mutually attached, and their sides are used to tightly attach to and press the triangular rubber. The reason for such a setting is that when it is necessary to press triangular rubbers of different specifications, the washer plates 312 can be correspondingly replaced so as to use washer plates 312 of appropriate sizes. And the washer plates 312 can have a slightly up-and-down movement range during use to avoid damage caused by excessive pressing force on the triangular rubber.

[0059] AsFigure 6 and Figure 8 As shown in Figure 8 , adjusting shafts 313 are also provided at the front and rear of the multi-layer roller 31. A number of ball bearings 314 with mutually abutting end faces are sleeved on the adjusting shafts 313. The size of the ball bearings 314 can be replaced according to the size of the washer pieces 312. The adjusting shafts 313 are provided for two purposes. On the one hand, the side faces of the washer pieces 312 are brought into contact with the side faces of the ball bearings 314, so as to adjust the pressing position of the washer pieces 312. On the other hand, the possible residual film on the side faces of the washer pieces 312 is scraped off through the friction with the side faces of the washer pieces 312.

[0060] In this embodiment, the horizontal position of the multi-layer roller 31 can be adjusted. The structure for achieving this purpose is as shown in Figure 6 and Figure 8 . Figure 6 and Figure 8 As shown in Figure 8 , an adjusting member 5 is provided on the frame 1. The adjusting member 5 includes sliding rods 53 horizontally arranged on the frame 1. A number of sliding rods 53 are provided. A sliding block 51 is slidably connected to the sliding rods 53, and the sliding block 51 can slide along the direction of the sliding rods 53. In addition, an adjusting cylinder 52 is fixed to the side face of the sliding block 51. The output shaft of the adjusting cylinder 52 is arranged downward and fixed to the top position of the multi-layer roller 31, so as to achieve the purpose of pressing during work and lifting when not working, which is convenient for operation.

[0061] As shown in Figure 6 and Figure 8 , the adjusting member 5 further includes an adjusting lead screw 54. The adjusting lead screw 54 is arranged parallel to the sliding rods 53. The adjusting lead screw 54 penetrates through the sliding block 51 and is threadedly connected thereto. A hand wheel 55 is also provided at the end of the adjusting lead screw 54. By rotating the hand wheel 55, the sliding block 51 can be driven to slide under the action of the thread, so as to adjust the horizontal position of the multi-layer roller 31, achieve the adjustment of the relative position of the multi-layer roller 31, and correspond to the pressing position of the triangular rubber 9 and the small film 8. The function of the adjusting cylinder 52 is to adjust the vertical position of the multi-layer roller 31.

[0062] As shown in Figure 6 and Figure 9 , horizontal guide rollers 61 and vertical guide rollers 62 are also provided at the foremost position of the frame 1. After the small film 8 is attached to the triangular rubber 9, the finished product can be guided into the next unit. Between the two vertical guide rollers 62, a number of adjusting rods 66 are further provided. The adjusting rods 66 include a shaft rod 661 arranged horizontally and a plurality of Fuller wheels 662 sleeved on the shaft rod 661. A number of the Fuller wheels 662 are arranged in close contact with each other.

[0063] As shown in Figure 6 and Figure 9 ,​​​​​​​​​​​As shown, there are three gaps left on each Flapper Wheel 662, and each gap is filled with a ball 663. The ball 663 is in an ellipsoidal shape. The function of the ball is to accurately guide the two triangular rubbers onto the conveyor belt through the alignment of the above-mentioned parts, ensuring accurate positioning of the triangular rubbers without wrinkles.

[0064] There are two purposes for setting the adjustment rod 66. One is to adjust the direction of the finished product through the adjustment rod 66 and play a shock-absorbing role during the adjustment process; the other is to roll and press tightly at the bottom of the triangular rubber through the relative rolling of the balls 663 on the Flapper Wheel 662, exhausting the air that may exist when the triangular rubber 9 and the small rubber sheet 8 are in contact, further improving the quality of the triangular rubber finished product.

[0065] The specific implementation manner of the present invention is as follows: The raw material enters the extruder 4 from the feed inlet, is heated into a molten state by the extruder 4, and then the molten material is lifted to the feed inlet of the calendering device 2 through the rubber material conveying channel 41. The calendering device 2 calenders and cuts the material into the shape of the required small rubber sheet 8. The small rubber sheet 8 is conveyed to the bottom of the laminating assembly 3 on the frame 1 through the calendering device 2. At this time, the conveying assembly 7 at the bottom of the laminating assembly 3 conveys the triangular rubber 9 formed in the previous unit to the designated position. After the small rubber sheet 8 is tightly attached to the surface of the triangular rubber, the two can be laminated and fixed through the thousand-layer roller 31, completing the bonding and fixing of the small rubber sheet 8 and the triangular rubber; before the small rubber sheet 8 enters the conveying assembly 7, the adjusting member 5 on the frame 1 can adjust the entering position and entering height of the small rubber sheet 8, thereby ensuring the accuracy of the lamination between the small rubber sheet 8 and the triangular rubber; the feeding and discharging of the present invention are completed through mechanical components, without manual replacement and overlapping of the rolled materials of the rubber sheets, greatly improving the production efficiency and the precision of the lamination of the triangular rubber, and improving the product quality.

[0066] In addition to the above embodiments, the present invention may have other implementation manners. All technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
