Description

Technical Field

[0001] This utility model belongs to the technical field of rubber-metal composite plates, specifically relating to a continuous film-tearing device for rubber-metal composite plates. Background Technology

[0002] Rubber-metal composite sheets are the core material of automotive brake damping pads, reducing braking noise by damping vibrations and sound wave transmission. Their typical structure is a sandwich of "metal substrate - adhesive layer - rubber functional layer," with a thickness typically ranging from 0.5 to 0.8 mm. They are installed on the back of the brake pad to block the transmission of frictional vibrations. During the manufacturing process, after the calendered rubber sheet is bonded to the metal substrate, a mold cloth / film is applied before vulcanization to create textures and patterns on the rubber surface. After vulcanization, the mold cloth / film is completely removed for subsequent surface coating processes.

[0003] Currently, the film-tearing process is usually done manually, which is labor-intensive and inefficient, seriously affecting the production efficiency of composite boards. Mechanical film-tearing devices have a simple structure, generally consisting of a winding shaft and pressure rollers. They cannot be used for continuous film tearing. When unloading the film roll from the winding shaft, the composite board conveying needs to be paused to allow for proper alignment of the film fabric joints. Therefore, they are not suitable for composite board assembly line production, reducing processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a continuous film-tearing device for the production process of rubber-metal composite boards, which features continuous film-tearing operation, automatic control and adjustment, and meets the requirements of assembly line processing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A continuous film-tearing device for rubber-metal composite sheets, characterized in that: it includes a frame with a support frame, the support frame is provided with a rotating rod, the middle part of the rotating rod is fixedly connected to a horizontal rotating shaft, the horizontal rotating shaft is positioned on the support frame by a bearing, the horizontal rotating shaft is connected to a first motor by a coupling, the two ends of the rotating rod are respectively provided with a winding shaft for film tearing and winding and a spare shaft, the winding shaft and the spare shaft are respectively driven by a second motor and a third motor, and a cutting mechanism is provided in the middle of the rotating rod.

[0007] Additional technical features of the continuous film-tearing device constituting the above-mentioned rubber-metal composite plate also include:

[0008] —It also includes controllers that are electrically connected to the first motor, the second motor, and the third motor respectively, the controllers including timers and / or sensors disposed on the frame for detecting the speed of the membrane movement;

[0009] The cutting mechanism includes a linear guide rail that is mounted on the middle of the rotating rod via a bearing seat. The linear guide rail is aligned with the horizontal rotating shaft. A blade is disposed inside the slider of the linear guide rail. The linear guide rail is electrically connected to the controller.

[0010] —The surfaces of the winding shaft and the spare shaft are provided with barbed needles for hooking the film fabric to form a winding.

[0011] Compared with the prior art, the continuous film-tearing device for rubber-metal composite panels provided by this utility model has the following advantages: The support frame on the frame of the device is connected to a rotating rod through a horizontal rotating shaft. The two ends of the rotating rod are respectively equipped with shafts for winding and tearing the film. One shaft closer to the film is the winding shaft, and the other shaft at the far end is the spare shaft. After the winding shaft reaches saturation, the horizontal rotating shaft is driven by a first motor to rotate, causing the spare shaft to reach the winding position. The winding shaft and the spare shaft are started and stopped by a second motor and a third motor respectively, and the cutting mechanism in the middle of the rotating rod cuts the film, facilitating the unloading of the film roll. This equipment realizes the continuous tearing of the film on the moving surface of the rubber-metal composite panel, avoiding the problem of needing to stop the composite panel machine during unloading in traditional single-axis film tearing. It meets the continuous processing requirements of the composite panel production line, improves the production efficiency of film tearing, and has the advantages of compact structure, convenient use, and economic durability.

[0014] The structure and working principle of the continuous film-tearing device for rubber-metal composite plates provided by this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] In the description of this utility model, unless otherwise stated, the orientation or positional relationship indicated in the terminology is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "set / equipped" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they 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.

[0017] like Figure 1 As shown, the continuous film-tearing device structure of the rubber-metal composite board includes a frame 2 with a support frame 1. The support frame 1 is provided with a rotating rod 3. The middle part of the rotating rod 3 is fixedly connected to a horizontal rotating shaft 4. The horizontal rotating shaft 4 is positioned on the support frame 1 by bearings. The horizontal rotating shaft 4 is connected to a first motor 51 by a coupling. The two ends of the rotating rod 3 are respectively provided with a winding shaft 31 for film tearing and winding and a spare shaft 32. The winding shaft 31 and the spare shaft 32 are driven by a second motor 52 and a third motor 53, respectively. A cutting mechanism is provided in the middle of the rotating rod 3.

[0018] Its working principle is as follows: The device frame 2 is placed on the rubber-metal composite plate production line. For example, after the vulcanization molding of rubber-metal composite plate a is completed, the mold cloth (film cloth) b on the surface of the rubber layer needs to be removed.

[0019] The film is torn off to allow for subsequent application of functional coatings. As the composite board a moves across the frame 2, the take-up shaft 31 at one end of the rotating rod 3 on the frame 2 is driven by the second motor 52 to tear the mold cloth b off the surface of the composite board and wind it up. As the composite board moves, the film roll on the take-up shaft 31 gradually reaches saturation. The first motor 51 drives the horizontal rotating shaft 4 to rotate. The spare shaft 32 at the other end of the rotating rod 3 is switched with the take-up shaft 31 and is driven to rotate by the third motor 53 to take over the continuous winding and tearing film operation, thus ensuring the continuous processing of the composite board.

[0020] It should be noted that a cutting mechanism is provided at the winding shaft 31. After the spare shaft 32 winds up the film, the cutting mechanism cuts the mold cloth b and the second motor 52 of the winding shaft 31 stops, making it easy to unload the film roll.

[0021] In the continuous film-tearing device structure constituting the aforementioned rubber-metal composite plate

[0022] --like Figure 2As shown, in order to realize the automatic control of the alternating operation of the take-up shaft 31 and the spare shaft 32, this device also includes a controller 7 electrically connected to the first motor 51, the second motor 52 and the third motor 53 respectively. The controller 7 includes a timer and / or a sensor 71 set on the frame 2 for detecting the speed of the membrane cloth movement. That is, according to the preset running speed of the composite board production line and the saturation of the membrane cloth winding, the timer feeds back the state that the winding is about to end (ensuring that when the rotating rod 3 rotates, the membrane cloth can meet the requirement of the two shafts being swapped and pressed against the spare shaft 32 for winding), starts the cutting mechanism to cut the mold cloth b, and stops the second motor 52 of the fully wound take-up shaft 31, and drives the third motor 53 to work at a timer so that the spare shaft 32 can take over the winding work from the take-up shaft 31.

[0023] The aforementioned electrical connections include necessary power lines, communication lines, solenoid valve seats, and electrical components such as sensors;

[0024] —Preferredly, the cutting mechanism includes a linear guide rail 61 mounted on the middle of the rotating rod 3 via a bearing seat. The linear guide rail 61 is aligned with the horizontal rotating shaft 4, meaning that one side of the rotating rod 3 is fixedly connected to the horizontal rotating shaft 4. Under its guidance, the rotating rod 3 can rotate, allowing the positions of the take-up shaft 31 and the spare shaft 32 to be interchanged. The linear guide rail 61 on the other side of the rotating rod 3 via the bearing seat can be relatively different. The blade 62 inside it can always be aligned with the running plane of the mold cloth. The blade 62 is set in the slider 63 of the linear guide rail 61. The slider 63 is initially located at the end of the linear guide rail 61 (the side of the mold cloth b), which will not affect the operation of the mold cloth. The linear guide rail 61 is electrically connected to the controller 7. That is, when the take-up shaft 31 and the spare shaft 32 work alternately, the linear guide rail 61 is activated, and the blade 62 in the slider 63 slides along the direction of the horizontal rotating shaft 4 (shaft) to cut the mold cloth b.

[0025] —To ensure that the new membrane fabric end can be wound on the spare shaft 32 after the membrane fabric is cut, the surfaces of the aforementioned winding shaft 31 and spare shaft 32 are provided with barbed needle surfaces 8 for hooking the membrane fabric to form a winding.

[0026] — Preferably, in order to facilitate the timely removal of the film roll on the winding shaft 31, the ends of the winding shaft 31 and the spare shaft 32 are fitted with baffles. The baffles are threaded to the ends of the shafts or the outer side of the baffles is positioned by tightening nuts. That is, through the detachable structure, the film roll can be quickly removed. The baffles can also limit the winding process of the film roll to ensure that the winding direction is consistent and that the film roll is evenly and neatly torn on the composite board.

[0027] The above-described embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the implementation of this utility model. Therefore, any other modifications or equivalent substitutions to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
