Technical Field
[0001] This utility model relates to the field of rubber preform molding technology, and in particular to a preliminary refining equipment for rubber preforms. Background Technology
[0002] Currently, the mixed rubber raw materials are in a colloidal state. Using equipment to fully mix them makes the colloidal material more uniform and completely eliminates air bubbles and voids. This ensures that the rubber material can be easily cut into small segments, and also ensures uniform material usage and convenient use of molding equipment.
[0003] The existing announcement number CN212045453U discloses a preliminary refining device for vulcanized rubber molding preforms, including a frame, a transmission mechanism disposed on one side of the frame, a set of refining stirring roller structures disposed on the upper part of the frame and connected to the transmission mechanism with gaps, and a material clamping and limiting block structure disposed between the refining stirring roller structures. The refining stirring roller structure includes a set of inner transmission roller shafts disposed in the roller body seat on the frame and a refining optical shaft body disposed outside the inner transmission roller shafts. The two inner transmission roller shafts rotate relative to each other through relative transmission gears in the transmission mechanism. The material clamping and limiting block structure is used to limit the concentrated crushing action of the material. The preliminary refining device for vulcanized rubber molding preforms with this structure is simple in structure and easy to use, ensuring uniform mixing of rubber gel material, and preventing the generation of air bubbles and pores during cutting. It further ensures accurate weight of the molding material and prevents the generation of air bubbles and pores inside the product, thereby improving product quality.
[0004] However, the aforementioned preliminary refining device for vulcanized rubber molding blanks is not convenient for adjusting the spacing of the refining optical axis during use, and cannot be applied to molding rubbers with different degrees of gelation. Utility Model Content
[0005] The purpose of this invention is to provide a preliminary refining device for rubber molding blanks, which solves the problem that the preliminary refining device for vulcanized rubber molding blanks is not convenient to adjust the spacing of the refining optical axis during use, and cannot be applied to rubber with different degrees of gelation for molding.
[0006] To achieve the above objectives, this utility model provides a preliminary refining device for rubber molding preforms, including a frame, an extrusion assembly, a feeding assembly, and a discharging assembly. The extrusion assembly includes an adjusting seat, an adjusting shaft, an adjusting roller, and fixing bolts. There are two adjusting seats, which are slidably connected to the frame and located on opposite sides of the frame. The adjusting shaft is rotatably connected to the adjusting seats and passes through the frame. The adjusting roller is fixedly connected to the adjusting shaft and located outside the adjusting shaft. There are two fixing bolts, which are threadedly connected to the adjusting seats and pass through the frame. The feeding assembly and the discharging assembly are connected to the frame.
[0007] The extrusion assembly further includes a movable plate, a limiting strip, and an adjusting motor. There are two movable plates, which are slidably connected to the frame and located on the outside of the adjusting shaft. There are multiple limiting strips, which are fixedly connected to the movable plates and located between the movable plates and the frame. The adjusting motor is fixedly connected to the movable plates and located on the outside of the movable plates.
[0008] The extrusion assembly further includes a fixed motor, a fixed shaft, and a fixed roller. The fixed motor is fixedly connected to the frame and located outside the frame. The fixed shaft is connected to the fixed motor and passes through the frame. The fixed roller is fixedly connected to the fixed shaft and located outside the fixed shaft.
[0009] The feeding assembly includes a feeding rack and a concentrator. The feeding rack is fixedly connected to the frame and located at the top of the frame. The concentrator is fixedly connected to the feeding rack and located in the middle of the feeding rack.
[0010] The discharge assembly includes a discharge seat and support rods. The discharge seat is fixedly connected to the frame and located at the bottom of the frame. There are multiple support rods, each fixedly connected to the discharge seat and located at the bottom of the discharge seat.
[0011] This utility model discloses a preliminary refining device for rubber molding blanks. The frame provides support for the device, the adjusting seat provides support for the adjusting shaft, and the adjusting shaft provides support and transmission for the adjusting roller. The adjusting roller cooperates with the fixed roller to extrude the rubber blank. The fixing bolt is used to fix the position of the adjusting seat to prevent slippage during use. When it is necessary to adjust the distance between the adjusting roller and the fixed roller, the fixing bolt is loosened, allowing the adjusting seat to move along the limiting strip with the moving plate. At the same time, the adjusting shaft and the adjusting roller move synchronously, changing the distance between the adjusting roller and the fixed roller. After adjustment, the position of the adjusting seat is fixed again with the fixing bolt to prevent slippage during extrusion. The rubber blank is then fed into the frame through the feeding assembly to facilitate extrusion and expel air bubbles from the rubber blank. This solves the problem that preliminary refining devices for vulcanized rubber molding blanks are inconvenient to adjust the distance of the refining shaft during use and cannot be applied to molding rubbers with different degrees of gelation.

The fixing bolt 105 is used to fix the position of the adjusting seat 102 to prevent the adjusting seat 102 from slipping during use. When it is necessary to adjust the distance between the adjusting roller 104 and the fixing roller 111, the fixing bolt 105 is loosened, so that the adjusting seat 102 moves along the limiting strip 107 with the moving plate 106, and at the same time drives the adjusting shaft 103 and the adjusting roller 104 to move synchronously, so that the distance between the adjusting roller 104 and the fixing roller 111 changes. After the adjustment is completed, the position of the adjusting seat 102 is fixed again by the fixing bolt 105 to prevent the position of the adjusting seat 102 from slipping during extrusion. Then, the rubber blank is fed into the frame 101 through the feeding assembly to facilitate the extrusion of the rubber blank and the discharge of air bubbles inside the rubber blank.
[0020] The system comprises two movable plates 106, each slidably connected to the frame 101 and located outside the adjusting shaft 103. Multiple limiting strips 107 are fixedly connected to the movable plates 106 and located between the movable plates 106 and the frame 101. An adjusting motor 108 is fixedly connected to the movable plates 106 and located outside the movable plates 106. The movable plates 106 provide support for the adjusting shaft 103 and the adjusting motor 108. The limiting strips 107 provide support and limiting for the movable plates 106. The adjusting motor 108 provides power to the adjusting shaft 103. The adjusting motor 108 and the fixed motor 109 rotate synchronously in opposite directions, facilitating the rotation of the fixed shaft 110 and the adjusting shaft 103, thus facilitating the extrusion of the rubber blank.
[0021] Secondly, the fixed motor 109 is fixedly connected to the frame 101 and located outside the frame 101. The fixed shaft 110 is connected to the fixed motor 109 and passes through the frame 101.

When it is necessary to adjust the distance between the adjusting roller 104 and the fixed roller 111, the fixing bolt 105 is loosened so that the adjusting seat 102 follows the moving plate 106 along the […]. The limiting bar 107 moves, simultaneously driving the adjusting shaft 103 and the adjusting roller 104 to move synchronously, thereby changing the distance between the adjusting roller 104 and the fixed roller 111.
