Description

Technical Field

[0001] The utility model belongs to the technical field of skeleton sealing ring processing, in particular to an automatic rubber vulcanizing machine. Background Art

[0002] A skeleton-type rubber seal is a seal made from a metal or non-metal skeleton and rubber material through a special process. Skeleton-type rubber seals typically consist of two parts: the rubber material and the skeleton. The skeleton is the key component that supports and secures the rubber material, while the rubber material provides the sealing function. Skeleton-type rubber seals are widely used in the fields of machinery, automobiles, aviation, metallurgy, and petroleum, playing a key sealing role in mechanical equipment, automobile wheels, oil seals, and other parts. Skeleton-type rubber seals have attracted widespread attention and application in the industrial field due to their excellent sealing performance and wear resistance, and their ability to withstand harsh environments such as high temperature, high pressure, and high speed.

[0003] The Chinese patent document with publication number CN116175684A discloses a flexible rubber segment processing device, which belongs to the field of rubber product processing technology. It includes a mounting platform and: a tape cutting mechanism, which is arranged on the mounting platform and is used to cut the rubber tape into segments to form rubber strips; a tape feeding mechanism, which is arranged on the mounting platform and is used to transport the wound rubber tape to the tape cutting mechanism; a rubber strip unloading mechanism, which is arranged adjacent to the mounting platform and is used to transfer the rubber strip unloading; a weighing and transferring mechanism, which is arranged on the mounting platform and is used to weigh and screen the cut rubber strips, and then transfer the good rubber strips to the rubber strip unloading mechanism.

[0004] In the processing of skeleton sealing rings, after the rubber strips are cut by the above-mentioned processing device, they are manually collected and placed in a molding machine for hot-melt molding. This greatly restricts the processing efficiency and quality of the skeleton sealing ring. In the process of combining the above-mentioned scheme with a rubber vulcanizer for automation modification, due to the soft, elastic and high friction properties of the rubber sheet, when the rolled rubber sheet is flattened and cut, the tension on the pulled rubber sheet is too high or too low, which easily causes distortion and conveying trajectory deviation. This is not convenient for the subsequent precise cutting of the rubber sheet, that is, it is not convenient for the amount control and uniform arrangement of the rubber strips in the rubber vulcanizer, and it is also not convenient for the subsequent automatic picking and turnover of the rubber strips. Utility Model Content

[0005] In order to overcome the technical problems in the vulcanization process of the skeleton sealing ring in the prior art, the manual placement of rubber strips leads to low processing efficiency, and the use of automated equipment is difficult to stably control the cutting and picking of the rubber strips; one purpose of the utility model is to provide a rubber automatic vulcanizer, by arranging two tension-adjusting rollers with adjustable spacing between the rolled rubber belt and the cutting part, the tension of the rubber belt is controlled by changing the contact area between the rubber belt and the tension-adjusting roller, and in addition, a gravity roller is provided to press the rubber belt onto the driving roller by gravity, which is used to drive the rubber belt to enter the cutting device evenly and stably, and can adaptively be compatible with rubber belts with different compositions, thicknesses, etc., for automatic feeding processing of different types of skeleton sealing rings.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a rubber automatic vulcanizing machine, comprising two tension adjustment rollers, a guide roller, a lower pressure roller, a friction roller, and a driving roller, which are arranged in sequence along the conveying direction of the rubber belt and are rotatably connected to the workbench, and each rotating shaft is arranged in parallel; a gravity roller is longitudinally slidably connected to the workbench directly above the driving roller, and the gravity roller presses the rubber belt against the upper end of the outer wall of the driving roller; wherein the rubber belt is sequentially abutted against the upper end of the outer wall of one of the tension adjustment rollers and the lower end of the outer wall of the other tension adjustment roller; two adjusting cylinders are provided on the workbench, and the two adjusting cylinders are respectively used to drive the two tension adjustment rollers to slide, and the axis distance between the two tension adjustment rollers can be adjusted.

[0007] The larger the spacing between the two tension-adjusting rollers, the straighter the rubber belt becomes, the smaller the contact area with the tension-adjusting rollers, and the lower the tension on the rubber belt. The larger the spacing between the two tension-adjusting rollers, the more the rubber belt bends, the larger the contact area with the tension-adjusting rollers, and the higher the tension on the rubber belt. After being guided by the rollers, the rubber belt is smoothly straightened, preventing wrinkles and facilitating automated, precise cutting. This allows for precise material selection for the skeleton seal ring, helping to improve processing quality. The entire process requires no human intervention, eliminating human interference and improving processing efficiency.

[0008] Specifically, two baffles are symmetrically arranged between the friction roller and the driving roller, and the rubber belt passes through the two baffles; the outer wall of the friction roller is evenly provided with anti-slip grooves, and the friction roller is located above the driving roller; the rubber belt is against the upper end of the outer wall of the friction roller, and the rubber belt is suspended between the two baffles.

[0009] Specifically, the workbench is provided with a lower table; two mutually parallel guide rails are provided at the lower end of the lower table; two T-shaped sliders are provided on the baffle, and the T-shaped sliders are located between the lower table and the guide rails.

[0010] The baffle limits the deviation of the conveying track of the rubber belt, ensuring uniform feeding to the cutting part; the sliding setting of the baffle is compatible with rubber belts of different widths; the rubber belt between the friction roller and the driving roller is suspended in the air, preventing the rubber belt from contacting the lower table surface, thereby limiting the transmission of the rubber belt under the action of friction; the anti-slip grooves prevent the rubber belt from collapsing downward under the action of gravity, that is, preventing the rubber belt from contacting the lower table surface.

[0011] Specifically, the lower pressure roller is located below the friction roller; the rubber belt abuts against the lower end of the outer wall of the lower pressure roller; a spring is provided between the lower pressure roller and the workbench, and the elastic force of the spring is used to make the lower pressure roller slide downward.

[0012] The elastic force of the spring increases the contact between the rubber belt and the anti-skid groove, further preventing the rubber belt from collapsing under the action of gravity, and also increases the tension of the rubber belt.

[0013] Specifically, the outer wall of the driving roller is coaxially provided with multiple annular grooves, and each of the annular grooves is evenly distributed along the axial direction of the driving roller; the upper end of the lower table is provided with multiple through openings, and the partition plate between two adjacent through openings is located in the annular groove; the upper end of the outer wall of the driving roller is located above the lower table.

[0015] By pressing the other end of the lifting frame, the gravity roller is lifted upwards for passing the rubber belt during the preliminary preparation process, and the lever principle is utilized to facilitate manual and labor-saving operation.

[0016] Furthermore, it includes a back plate, which is longitudinally arranged on the workbench and is located on the side of the drive roller away from the friction roller; a cutter, which is longitudinally slidably connected to the end of the back plate close to the drive roller; a rectangular opening, which is arranged on the cutter; a cutting motor, which is arranged on the workbench; wherein a cam is provided on the output shaft of the cutting motor; the cam is rotatably connected in the rectangular opening; the axis of the cam is parallel to and does not overlap with the axis of the output shaft of the cutting motor; a V-shaped groove is provided at the lower end of the cutter, and the middle of the V-shaped groove is higher and the two ends are lower.

[0017] The eccentric rotation of the cam drives the cutter to slide back and forth; during the V-shaped cutting process, the cutting starts from the two ends first, and gradually extends and cuts off towards the middle, preventing the rubber strip from warping up due to pressure during the cutting process, which helps to ensure subsequent automatic picking.

[0018] Furthermore, it includes a rubber strip support plate, which is rotatably connected to the workbench; a gantry, which slides back and forth between the rubber strip support plate and the abutment plate; a rubber strip needle, which has a plurality of rubber strip needles arranged along a linear pattern and are all longitudinally slidably connected to the gantry; a comb plate, which is longitudinally slidably connected to the rubber strip needle; wherein the comb plate can be selectively located above or below the rubber strip needle; a plurality of linearly arranged grooves are provided at the upper end of the abutment plate; the rubber strip needle can be selectively inserted into the corresponding groove.

[0019] The rubber strip needle penetrates the cut rubber strip and is inserted into the groove to pick up the rubber strip and transfer it to the rubber strip supporting plate. The comb plate slides relative to the rubber strip needle to scrape off the rubber strip inserted on the rubber strip needle.

[0020] Furthermore, it includes a skeleton support plate, which is horizontally slidably connected to the workbench; a positioning column, which has a plurality of evenly distributed positioning columns and is arranged in a longitudinal array on the workbench, and a plurality of skeletons are sleeved on the positioning columns; a lifting plate, which is longitudinally slidably connected above the skeleton support plate and is used to lift the skeleton upward; wherein a U-shaped bracket is longitudinally slidably connected to the workbench, and the U-shaped bracket can optionally abut against the lower end of the lifting plate and drive it to slide upward; a U-shaped opening is provided on the U-shaped bracket, and the skeleton support plate is located in the U-shaped opening.

[0021] The skeleton support plate can slide outward from the U-shaped opening to facilitate the replenishment of the skeleton; the U-shaped bracket moves the skeleton upward to facilitate the movement of the automation device.

[0022] Furthermore, it includes a hot flip mold, which is slidably connected above the hydraulic press, and is used to heat the skeleton and the rubber strip at the same time; a transverse seat, which is horizontally slidably connected between the hot flip mold, the skeleton support plate, and the rubber strip support plate; a skeleton suction cup, which is longitudinally slidably connected to the transverse seat and can selectively move between the skeleton support plate and the hot flip mold; a glue mesh needle, which has a plurality of glue mesh needles arranged in an array, and are longitudinally slidably connected to the transverse seat, and can selectively move between the rubber strip support plate and the hot flip mold; wherein a mesh plate is longitudinally slidably connected to the glue mesh needle; the mesh plate can be selectively located below or above the glue mesh needle.
