Description

Technical Field

[0001] This utility model relates to a preheating mechanism for enhancing the efficiency of a vulcanizing machine, belonging to the field of vulcanizing machine technology. Background Technology

[0002] In the operation of a vulcanizing machine, the preheating of the mold plays a crucial role in the efficiency of the entire vulcanizing process and the product quality. Chinese patent CN214419337U discloses an automatic preheating vulcanizing machine, which includes a mounting plate, a hydraulic tank, a servo motor, a vulcanizing plate, and a heating tube. The hydraulic tank is located on the upper left side of the mounting plate, and a movable plate is connected inside the hydraulic tank. A push rod is installed on the outside of the movable plate. A sleeve is fixed to the upper end of the hydraulic tank. A bearing plate is connected to the upper end of the fixed rod. A guide rod is connected inside the mounting block. A heating tube is installed on the lower surface of the bearing plate.

[0003] In summary, the aforementioned patent achieves preheating of the mold by setting up heating tubes, but the heating range is difficult to adjust flexibly. For small molds, the aforementioned patent cannot accurately focus the heat, resulting in a large amount of heat being lost in the surrounding useless areas, causing energy waste. When facing large or irregularly shaped molds, it cannot expand the heating coverage in a timely and effective manner, resulting in uneven preheating of the mold and affecting the vulcanization effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a preheating mechanism for enhancing the efficiency of a vulcanizing machine, which enables flexible adjustment of the heating range of the mold to meet the preheating requirements of molds of different sizes and shapes, thereby improving preheating efficiency and energy utilization.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a preheating mechanism for enhancing the efficiency of a vulcanizing machine, characterized in that it includes: a frame, a fixing plate fixed on the side of the frame, and a vulcanizing mold provided on the fixing plate, and a hot pressing mechanism provided on the top of the frame. The fixed plate has several sets of sliding grooves, and a slide bar is slidably connected in the sliding groove. Several sets of heating units are installed on the top of the slide bar, and a rack is fixed on the side of the slide bar. Several sets of gears are installed on the bottom of the fixed plate through bearings, and the gears mesh with the rack. The front end of the fixed plate is provided with a driving mechanism, which is used to drive the slider to move laterally.

[0006] Preferably, the hot pressing mechanism includes a hydraulic cylinder, which is fixed through the top of the frame, and a hot pressing plate is fixed to the output end of the hydraulic cylinder.

[0007] Preferably, the slide bars are provided in five groups, and a gear is provided between each adjacent group of slide bars.

[0008] Preferably, each set of slide bars is provided with 5-10 heating units at the top, and the top of the heating unit is provided with a wear-resistant heat-conducting sheet.

[0009] Preferably, the driving mechanism includes a lead screw, which is laterally disposed at the front end of the fixed plate, and a movable plate is threadedly connected to the lead screw. The movable plate is connected to a set of slide bars through a connecting plate. A motor is fixed on the outside of the fixed plate, and the output end of the motor is connected to the lead screw.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the coordinated operation of slides, slide bars, racks and gears, multiple sets of slide bars can move synchronously in opposite directions under the drive mechanism, thereby flexibly adjusting the distribution range of the heating unit. For small molds, the heating unit can be concentrated and the heat can be precisely focused to avoid energy waste. For large or irregular molds, the heating coverage area can be expanded to ensure that all parts of the mold can be effectively preheated. This solves the problems of fixed heating range and poor adaptability of existing preheating mechanisms, significantly improving the compatibility with molds of different sizes and shapes. Moreover, since the heating range can be flexibly adjusted according to the mold specifications, the heat loss to useless areas can be reduced, effectively reducing the energy consumption per unit product and helping to reduce the production cost of enterprises. The heating unit is adjusted by means of racks, gears and lead screws, which has higher stability and durability compared to complex electronic control adjustment components. Moreover, a single drive mechanism can drive multiple sets of slide bars to move synchronously, eliminating the need for manual adjustment of each heating unit, greatly shortening the adjustment time and improving the operating efficiency and production preparation speed of the equipment.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 This utility model provides a technical solution: A preheating mechanism for enhancing the efficiency of a vulcanizing machine includes: a frame 1, a fixing plate 2 fixed to the side of the frame 1, a vulcanizing mold 3 provided on the fixing plate 2, and a hot pressing mechanism 4 provided on the top of the frame 1. The fixed plate 2 has several sets of sliding grooves 5, and a sliding strip 6 is slidably connected in the sliding groove 5. Several sets of heating units 7 are installed on the top of the sliding strip 6. A rack 8 is fixed on the side of the sliding strip 6. Several sets of gears 9 are installed at the bottom of the fixed plate 2 through bearings, and the gears 9 mesh with the rack 8. The front end of the fixed plate 2 is provided with a drive mechanism 10, which is used to drive the slide bar 6 to move laterally.

[0016] Furthermore, when the drive mechanism 10 drives the slide bar 6 to move laterally in the slide groove 5, the rack 8 on the side of the slide bar 6 moves synchronously, and the gear 9 meshing with the rack 8 rotates accordingly, thereby driving the adjacent slide bars 6 to move in the opposite direction, realizing the staggered linkage of multiple sets of slide bars 6, so that the heating unit 7 at the top of the slide bar 6 can adjust the distribution range, and cooperate with the hot pressing mechanism 4 to complete the precise preheating of the vulcanizing mold 3.

[0017] Heating unit 7 is a heating tube with a closed structure. It has a heating wire inside and the outside of the heating wire is filled with insulating and heat-conducting material. The outer shell of the heating tube is made of stainless steel. The wear-resistant heat-conducting sheet is fixed to the top of the heating tube.

[0018] In this embodiment: the hot pressing mechanism 4 includes a hydraulic cylinder 401, which is fixed to the top of the frame 1, and a hot pressing plate 402 is fixed to the output end of the hydraulic cylinder 401.

[0019] Furthermore, the hydraulic cylinder 401 serves as a power source, and when its output end extends or retracts, it drives the hot press plate 402 to move up and down. When the hot press plate 402 moves down, it can close with the vulcanizing mold 3 to perform vulcanization operations.

[0020] In this embodiment: five sets of slide bars 6 are provided, and a gear 9 is provided between each adjacent set of slide bars 6.

[0021] Furthermore, the five sets of slide bars 6 are connected by adjacent gears 9. When one set of slide bars 6 moves, the gear 9 rotates under the action of the rack 8, driving the other slide bars 6 to move synchronously in the opposite direction, expanding the adjustment range of the heating unit 7 and improving the adaptability to molds of different sizes.

[0022] In this embodiment: each set of sliders 6 is provided with 5-10 heating units 7 at the top, and the top of the heating unit 7 is provided with a wear-resistant heat-conducting sheet.

[0023] Furthermore, the 5-10 heating units 7 at the top of each set of slide bars 6 provide a heat source. The heat distribution is adjusted by moving the slide bars 6. The wear-resistant heat-conducting plates at the top of the heating units 7 enhance the heat transfer efficiency, reduce heat loss, and at the same time improve the wear resistance of the heating units 7 when in contact with the mold, thus extending their service life.

[0024] In this embodiment: the drive mechanism 10 includes a lead screw 1001, which is laterally arranged at the front end of the fixed plate 2, and a movable plate 1002 is threadedly connected to the lead screw 1001. The movable plate 1002 is connected to a set of slide bars 6 through a connecting plate 1003. A motor 1004 is fixed on the outside of the fixed plate 2, and the output end of the motor 1004 is connected to the lead screw 1001.

[0025] Furthermore, the motor 1004 outputs power to drive the lead screw 1001 to rotate. The lead screw 1001 is threadedly engaged with the movable plate 1002, thereby driving the movable plate 1002 to move laterally. The movable plate 1002 drives a set of slide bars 6 to move through the connecting plate 1003, and then through the rack 8 and gear 9, realizes the synchronous misaligned movement of all slide bars 6.

[0026] The workflow of this embodiment is as follows: The fixed plate 2 on the side of the frame 1 and the hot pressing mechanism 4 on the top provide stable support. The fixed plate 2 supports the vulcanizing mold 3 on one hand, and provides a sliding track for the slide bar 6 through the opened slide groove 5 on the other hand, ensuring that the slide bar 6 can only move stably in the lateral direction. When it is necessary to adjust the heating range, the motor 1004 starts and drives the lead screw 1001 to rotate. The lead screw 1001 drives the movable plate 1002 to move laterally in a straight line. The movable plate 1002 transmits power to a set of slide bars 6 through the connecting plate 1003. When the slide bar 6 moves, the rack 8 fixed on its side moves synchronously. Since the rack 8 meshes with the gear 9 installed at the bottom of the fixed plate 2 through the bearing, the gear... Gear 9 rotates with the movement of rack 8. When gear 9 rotates, it drives the rack 8 on the adjacent slide 6 to move in the opposite direction, causing the adjacent slide 6 to move in opposite directions along the slide groove 5, such as one group to the left and one group to the right. Multiple groups of slide 6 are driven sequentially by gear 9 to realize the staggered and reverse linkage of all slide 6. Finally, it drives the heating unit 7 installed on the top of slide 6 to expand or shrink the distribution range to adapt to vulcanizing molds 3 of different sizes. After the heating unit 7 is powered on, it generates heat and transfers the heat to the vulcanizing mold 3 through the wear-resistant heat-conducting plate on the top to complete the preheating. After the preheating is completed, the hydraulic cylinder 401 is started, and its output end pushes the hot pressure plate 402 to move down and close with the vulcanizing mold 3 to realize the vulcanization operation.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
