[0002] Rubber composite steel plate is a new type of composite material, mainly based on various types of steel plates, which are composited with rubber after surface treatment. The thickness and material of the rubber coating or attached film layer are determined according to its application purpose and use occasion. Compared with traditional steel leaf springs, the rubber composite steel plate used in automobile shock absorbers has stronger elastic buffering performance, good weather resistance, good wear resistance and fatigue resistance, longer service life, and good market application value.

[0003] At present, in the production process of rubber composite steel plate, rubber sheets need to be laid on the surface and bottom of the steel plate respectively. In order to prevent the rubber sheets from sticking during the vulcanization process, it is best to use isolation means, such as pressing a layer of isolation film after laying the rubber sheet to form a composite steel plate with rubber films on the top and bottom. Only in this way can the vulcanization molding be guaranteed to be regular after entering the vulcanizer, and the rubber sheets will not overflow and stick. Such a production process is relatively cumbersome and mostly manual, resulting in low production efficiency, inconsistent manufacturing quality and standards of composite plates, and reduced use effect of rubber composite steel plates.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0021] like Figure 1 As shown, the structure of the rubber composite steel plate coating vulcanization device includes a frame 1 on which a conveyor belt 2 is set, the rear end of the conveyor belt 2 is connected to the vulcanizer 3, and the front end of the conveyor belt 2 is provided with a first laying roller 21. The lower part of the frame 1 is provided with a first roller group for coating glue and film on the bottom surface of the steel plate c, which includes a lower glue roller 41 and a lower film roller 42, which respectively lay the lower layer of rubber a and the lower layer of isolation film b in the conveyor belt 2 through the first laying roller 21, and the bottom surface of the steel plate c presses the lower layer of rubber a; the upper part of the frame 1 is provided with a second roller group for coating glue and film on the surface of the steel plate, which includes an upper glue roller 51 and an upper film roller 52, which respectively lay the upper layer of rubber e and the upper layer of isolation film in the conveyor belt 2 through one or two second laying rollers 22, and the upper layer of rubber e presses the surface of the steel plate.

[0022] Its working principle is as follows: the rear end of the conveyor belt 2 in the frame 1 of the device is connected to the vulcanizer 3, and the first roller group at the lower part of the frame 1 includes a lower rubber roller 41 and a lower film roller 42, which transport the lower layer of film a and the lower isolation film b to the first laying roller 21 at the front end of the conveyor belt 2, and lay them into the conveyor belt 2, and the lower layer of film a is located above the lower isolation film b, and the bottom surface of the steel plate is pressed onto the lower layer of film a; the second roller group at the upper part of the frame 1 includes an upper rubber roller 51 and an upper film roller 52, and lays the upper layer of film e and the upper isolation film into the conveyor belt 2 through the second laying roller 22, and the upper layer of film e is pressed onto the surface of the steel plate, and the upper isolation film b is located above the upper layer of film e. After the steel plate c is coated with rubber film on the upper and lower sides, it enters the vulcanizer 3 at the rear end of the conveyor belt 2 for overall vulcanization.

[0023] It should be noted that the number of the second laying rollers 22 is two ( Figure 1 As shown), the upper glue roller 51 and the upper film roller 52 have independent pressing roller shafts respectively, and the upper glue roller 51 is located in front of the upper film roller 52, and the upper film e is first pressed on the surface of the steel plate, and the upper film roller 52 at the rear then presses the upper isolation film b on the upper film e;

[0024] In another structure, the second laying roller can also be one, that is, the glue roller 51 and the upper film roller 52 are linked, the upper film roller 52 is located between the glue roller 51 and the second laying roller, the glue roller 51 conveys the upper film e to the upper film roller 52, and the upper film roller 52 synchronously conveys the upper film e and the upper isolation film b to the second laying roller, and presses them on the surface of the steel plate c in turn.

[0025] In the structure constituting the above-mentioned rubber composite steel plate coating vulcanization device,

[0026] ——As a preferred embodiment, the film roll installed on the lower rubber roller 41 and the upper rubber roller 51 is a clamping roll 6 containing an isolation cloth 61, which prevents the rubber sheet from sticking to the roller shaft and is not easy to peel off. The film and the isolation cloth 61 are synchronously wound to form a clamping roll 6. When unwinding, the film and the isolation cloth 61 move synchronously. The film is conveyed to the conveyor belt 2 by the first and second laying rollers, and the isolation cloth 61 needs to be recovered in time. Therefore, a winding roller shaft group is arranged on the side of the lower rubber roller 41 and the upper rubber roller 51. The winding roller shaft group includes a driving pair of rollers and a winding roller 72 arranged above it, that is, the three rollers are in a triangular shape. The driving pair of rollers rotates in the same direction, driving the winding roller 72 to rotate in the opposite direction, and the isolation cloth 61 released from the clamping roll 6 is retracted into a roll. When the isolation cloth 61 moves from the rubber roller to the winding roller 72, in order to keep the tension state, a buffer roller shaft group 60 is arranged on the frame 1 between the two, which is composed of three roller shafts arranged in a triangle, and the isolation cloth 61 passes around the roller shafts in sequence;

[0027] ——Furthermore, the winding roller shaft groups of the lower rubber roller 41 and the upper rubber roller 51 are synchronized through a linkage mechanism, and the linkage mechanism includes a transmission chain 81 between the two driving rollers, and a sprocket 82 cooperating with the transmission chain is arranged at the end of the driving roller. Since the lower layer coating rate and the upper layer coating rate are consistent, that is, the unwinding speed of the lower rubber roller 41 and the upper rubber roller 51 are consistent, the winding of the isolation cloth 61 of the winding roll 6 is preferably consistent with the unwinding rate of the film, ensuring that the upper film e and the lower film a in the conveyor belt 2 will not be redundant or stretched, and the winding of the upper and lower isolation cloths 61 will not be redundant or stretched;

[0028] ——Since the winding roller shaft group of the lower rubber roller 41 and the upper rubber roller 51 realizes synchronous linkage through the transmission chain 81, it provides conditions for using a power mechanism to drive. The frame 1 is provided with a servo motor 80, and the drive shaft sleeve sprocket 82 of the servo motor 80 is meshed with the transmission chain 81 to drive the driving roller pair of the winding roller shaft group to move synchronously. The transmission structure of the chain 81 and the sprocket 82 is simple, which is convenient for equipment installation and debugging, and has a good linkage effect;

[0029] The driving roller pair is composed of an active roller 70 and a passive roller 71. The transmission chain 81 is meshed with the sprocket of the active roller 70. A hand wheel 83 is arranged at the end of the active roller 70. A clutch is arranged between the hand wheel 83 and the active roller 70. Figure 2 As shown, the clutch includes a shift fork 91, a release bearing 92 mounted on the shaft of the active roller 70, a sprocket of the active roller 70 mounted on the central shaft tube 90 of the handwheel, a clamping mechanism 93 consisting of convex teeth and grooves is provided between the side of the release bearing 92 and the central shaft tube 90 of the handwheel 83, the fulcrum of the shift fork 91 is arranged on the frame 1, and the swinging shift fork 91 makes the release bearing 92 of the clutch move along the axial direction of the active roller 70, so as to realize the combined transmission of the active roller 70 and the sprocket 82 on the handwheel 83, thereby realizing the switching between the motor-driven and manual rotation modes of the active roller;

[0030] It should be noted that the release bearing 92 is sleeved on the active roller 70, and its inner side is connected to the shaft of the active roller 70 through a sliding groove and a sliding strip structure along the axial direction, that is, the release bearing can slide relatively along the axial direction, but moves synchronously with the active roller 70 during circumferential rotation. Therefore, after the fork 91 pushes the release bearing 92 to the central shaft of the handwheel and is positioned through the engaging mechanism 93, the transmission chain 81 driven by the motor drives the active roller 70 to rotate; when the fork 91 pushes the release bearing 92 away from the central shaft tube 90 of the handwheel, that is, the engaging mechanism 93 fails to separate, the transmission chain 81 driven by the motor cannot drive the active roller 70 to rotate, and the rotation of the active roller 70 is achieved by turning the handwheel 83;

[0031] --like Figure 3As shown, as a process improvement of rubber-composite steel plate, the rubber layer on the bottom surface of the steel plate is in the form of cloth pattern, so after laying the lower layer of film a on the bottom surface of the steel plate, it is necessary to press a layer of mold cloth g, for this purpose, the first roller group located at the lower part of the frame 1 also includes a mold cloth roller 10, which is located between the lower rubber roller 41 and the lower film roller 42, and the mold cloth g is laid between the lower isolation film b and the lower film a through the first laying roller 21, that is, the lower isolation film b, the mold cloth g, and the lower film a are laid in the conveyor belt 2 in sequence through the first laying roller 21;

[0032] ——Furthermore, since the lower film a on the bottom surface of the steel plate is pressed against the mold cloth g, the lower isolation film b loses its function after the film is vulcanized and formed. After the composite plate is conveyed out of the vulcanizer 3, the lower isolation film b needs to be peeled off. For this purpose, a recovery reel 11 is provided at the rear end of the above-mentioned frame 1 to peel off the lower isolation film b of the coated rubber composite steel plate after vulcanization entering the vulcanizer 3 from the mold cloth g. The specific position of the recovery reel 11 can be set below the frame 1, and the lower isolation film b is connected to the recovery reel 11 from the bottom of the vulcanizer 3 outlet.

[0033] The above-described implementation modes are only used to illustrate the technical solution of the utility model, and are not limiting conditions for the implementation of the utility model. Therefore, any other modifications or equivalent replacements of configuration dimensions and internal structures made to the technical solution of the utility model, as long as they do not depart from the spirit and scope of the technical solution of the utility model, should be included in the scope of the claims of the utility model.
