Description

A horizontal tape arrangement mechanism matched with a screw compressor

technical field

The invention relates to a tape fixing mechanism, specifically a horizontal tape arrangement mechanism matched with a screw compressor, and belongs to the technical field of tape packaging.

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.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Referring to Figure 1-11, a longitudinal tape arrangement mechanism matched with a screw compressor, including a tape fixing device, a tape support, and a bracket device; the tape fixing device includes: a two-stage split shaft 4; The first section of the rod and the second section of the rod to be disassembled/installed; each section of the rod is provided with a first pin hole, and a horizontal pin 401 is installed on the first pin hole; the tape fixing seat 2; the tape fixing seat 2 is in the shape of a circular platform, a pair of adhesive tape fixing seats 2 are respectively sleeved and fixed on the first section of the rod and the second section of the rod, the small end of the circular table is inward; the tape 1; the tape 1 is ring-shaped, and the inner diameter of the tape is between the tape Between the outer diameters of the large end and the small end of the holder 2; the adhesive tape support member is cylindrical; the support device includes a support arm, a butterfly-shaped angle adjustment disc 9 on the tooth surface, and a connecting arm; the support arm is L One end is connected to the top of the screw compressor, and the other end is adjusted with the angle adjustment disc 9, the angle adjustment disc 9 is fixedly connected with the tape support through the connecting arm, and the tape fixing device is installed on the tape support

Referring to Fig. 4, a retaining ring groove and a second pin hole are respectively provided on the first section of the rod and the second section of the rod, the retaining ring 3 is clamped in the retaining ring groove, and the second pin is arranged in the second pin hole shaft, the retaining ring 3 and the second pin shaft make the adhesive tape holder 2 axially positioned.

Referring to Figures 2-4, the two-section rods of the two-stage split shaft 4 have connection ends and outer ends respectively. The connecting end of the segment rod has a blind hole, and the hole wall of the blind hole has an L-shaped groove. A magnet is fixed at each end to form a pair of magnets with opposite magnetic poles; the end of the L-shaped slot has a small slot along the axial direction, and when the lock pin slides into the small slot along the L-shaped slot, the pair of magnets are sucked tightly. At the same time, the small groove prevents relative rotation between the first and second section rods.

In this embodiment, the lengths of both sides of the support arm can be adjusted telescopically.

In this embodiment, referring to FIG. 11 , the support device is driven by the power mechanism and can rotate around the circumferential direction of the outer wall of the screw compressor as a whole.

The specific installation is divided into three 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: fix the adhesive tape fixing device on the adhesive tape support 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.

When the longitudinal tape arrangement mechanism of the screw compressor works, see Figure 11, as the molding material is pushed out from the discharge port of the screw compressor, the tape is spirally wound outside the material, and the material packaging effect is good.

The above are the preferred embodiments of the present invention. Those skilled in the art can also make various transformations or improvements on this basis. Under the premise of not departing from the general concept of the present invention, these transformations or improvements should all belong to the claims of the present invention. within the range.
