Background technique

The spiral compression molding machine has the characteristics of fast and uninterrupted compression molding of materials, and can compress a large amount of loose materials into a compact and regular shape, which is convenient for storage and transportation. In the field of agricultural production, materials such as crop straw and silage feed have a large amount and small specific gravity, and can be compressed and bundled to make a compact cylindrical entity, and the screw compression molding machine can complete this work. However, for such agricultural materials, after compression molding, if the materials such as ropes and tapes are not fixed in time, the materials will disperse after leaving the molding machine. Therefore, it is necessary to use adhesive tape and its installation structure.

During the working process of the screw compressor, it is necessary to wrap the tape on the outside of the molding material to effectively prevent the material from spreading. Therefore, it is necessary to arrange a tape conveying mechanism in different directions of the cylindrical entity, and to wrap the tape on the surface of the cylindrical entity. Simultaneously apply a compressive force, so that the intersecting tapes stick together to form a network. In addition, during the working process of the tape conveying mechanism, a new tape needs to be replaced after a roll of tape is used up. In order to improve work efficiency, it is necessary to design a mechanism that can easily replace the tape.

During the specific installation, the operation is divided into four parts:

The first part: A nylon round table with a hole in the middle is inserted into the shaft, and the round table is fixed in the axial direction by a split pin and a retaining ring. The diameter of the middle hole of the round table is slightly larger than the shaft diameter, and the round table can rotate around the shaft flexibly. When the two sections of the shaft are combined, the two round tables form the shape shown in Figure 1, which is thinner in the middle and slightly larger in diameter at both ends. , firmly fixed. When in use, put the tape ring between the two round tables, push the two shaft sections to a certain position in the middle, and then rotate the two shaft sections relatively. Locked, the two shaft sections are not easy to separate automatically. After the adhesive tape is used up, the operator grabs the outer ends of the two shaft sections and pulls them outward, then turns them at a certain angle, and then pulls them outward to separate the two sections, replace the adhesive tapes and put them back together. Utilize this mechanism to realize quick tape replacement.

The second part: When pushing the horizontal pin 401 to the bottom position of the U-shaped groove, continue to press down, because the two-stage split shaft 4 has a cohesive force towards the middle under the action of the magnet, so the horizontal pin 401 will automatically be drawn into the groove The groove 602 and the groove 602 in the shape of a superior arc form a good fit with the cross pin 401, so that the mechanism can be stably fixed when the mechanism is working, and the cross pin 401 is not easy to escape from the "U" shaped groove when there is no external force. When the adhesive tape needs to be removed and replaced, the two horizontal pins 401 are pulled outward and upward at the same time, and the whole fixing device can be taken out from the U-shaped groove.

The third part: the installation of the horizontal tape layout structure: fix the tape fixing device on the tape supporting welding structure shown in Figure 9, and connect it to the bracket in Figure 8 by welding through two matching tooth surface dish-shaped angle adjustment discs. Structural features of the connecting part: the adhesive tape support welding structure and the bracket welding structure are connected through a pair of dish-shaped angle adjustment discs 9 on the tooth surface. One of the tooth surface disc-shaped angle adjustment discs 9 is affixed to the adhesive tape support welding structure, and the other is affixed to the support welding structure. The characteristics of the dish-shaped angle adjusting disc 9 on the tooth surface are shown in Figures 6-7 and 10. The surface of the dish-shaped disc is processed with teeth radiating outward along the radial direction. The tooth profile is shallow near the center and gradually deepens outward. The faces of the two discs just engage. Its function is: during work, the faces of the two discs are engaged and assembled together, and clamped and fixed with bolts, so as to connect the two parts of the tape support welding and the bracket welding. After loosening the clamping bolts of the two dish-shaped disks, the angle between the surfaces of the two disk-shaped disks can be adjusted conveniently, so as to adjust the angle at which the tape is conveyed by the transverse tape winding conveying mechanism.

Part 4: Installation of the vertical tape arrangement mechanism: see Figure 11-18, two rocker arms are slidingly sleeved on the rocker arm coupling shaft, and the other end of the rocker arm has a "U"-shaped groove for installing the compression wheel shaft. The pressing wheel is made of nylon material, and the sliding sleeve is on the pressing wheel shaft, which can rotate freely. The diameter of the inner middle part of the pinch wheel becomes larger, which reduces the direct contact area between the shaft and the pinch wheel space, reduces the rotational resistance of the pinch wheel around the shaft, and enables flexible sliding. The shape of the compression wheel is made into a waist shape with a thin center and slightly thicker ends. Its function is: the pressure wheel presses the tape on the surface of the cylinder formed by compression of the material, the arc of the waist-shaped pressure wheel fits the cylindrical surface, and the tape It is evenly pressed on the surface of the cylinder, and the fit is more uniform. A spring fixing pin is fixedly connected to the rocker arm, and a spring fixing pin is also fixedly connected to the vertical plate on the side of the support. Tension springs are installed on the two fixing pins to press the rocker arm and the pressing wheel tightly against the cylindrical shape of the molding material. face.

When the tape automatic winding and bundling device matched with the screw compressor is working, see Figure 19, as the molding material is pushed out from the outlet of the screw compressor, the horizontal tape arrangement mechanism rotates around the inner ring 11 of the bearing along with the outer gear ring 10 , the horizontal tape is spirally wound outside the material, at the same time, the pressing wheel of the longitudinal tape arrangement mechanism compresses the material, and the tape is stretched longitudinally to package the formed material. Material packaging effect is good.
