Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts of tobacco equipment, in particular to a new flat shaft used for a YJ27 filter tip assembling machine. Background Art

[0002] The flat shaft of the YJ27 filter tipping machine is suitable for the shearing paper cutting device. Its functions are: ① to ensure that the conveying line speed of the tipping paper is consistent with the line speed of the paper cutting wheel surface during the paper cutting process of the paper cutting knife and the paper cutting wheel; ② to quickly pull the tipping paper back to the initial cutting position when the paper cutting knife and the paper cutting wheel are cutting the paper roll.

[0003] In actual production, in order to reduce the tar content of cigarettes, one or two rows of holes for smoke passage are often punched in advance on the tipping paper. This type of tipping paper is called pre-punched tipping paper. During production, the tipping glue will seep out from the holes of the pre-punched tipping paper and stick to the surface of the flat shaft to form glue scale. Since the surface of the flat shaft and the surface of the pre-punched tipping paper have a large friction force, the glue scale can easily puncture the surface of the pre-punched tipping paper, thereby forming defective cigarettes in subsequent processes, causing great waste. Therefore, in order to prevent the glue scale from puncturing the surface of the pre-punched tipping paper, a glue groove is processed on the surface of the flat shaft corresponding to the pre-punched holes of the pre-punched tipping paper.

[0004] As there are many brands of tipping paper currently, there are also many types of pre-punched tipping paper. The pre-punched position of each pre-punched tipping paper is different. In order to prevent the glue scale from puncturing the surface of the pre-punched tipping paper, it is necessary to prepare a variety of flat shafts with different glue groove center distances to adapt to the corresponding pre-punched tipping paper. However, the existing flat shafts are all one-piece structures. Each time the flat shaft is replaced, its position needs to be calibrated and adjusted for a long time, which leads to a long repair time, affects the efficiency of the equipment, and makes the reliability and stability of the final product cannot be guaranteed. Utility Model Content

[0005] In view of this, the utility model provides a new flat shaft for the YJ27 filter tip installation machine, which can solve the technical problem that when replacing the flat shaft with an integrated design, it is necessary to perform a long-term calibration and adjustment of its posture, resulting in a long repair time, affecting the efficiency of the equipment, and making it impossible to guarantee the reliability and stability of the final product.

[0026] like Figures 3 to 5 As shown, the utility model provides a new flat shaft for a YJ27 filter tip installation machine.

[0027] It includes a mounting piece 1 and a flat shaft sleeve 2 connected to the mounting piece 1 by a key. The mounting piece 1 includes a shaft body 101 and a connecting shaft 102 located at its end. A keyway 103 is provided at the connection between the shaft body 101 and the connecting shaft 102. A key body 201 is provided at the end of the flat shaft sleeve 2. The connecting shaft 102 passes through the interior of the flat shaft sleeve 2 and the mounting piece 1 and the flat shaft sleeve 2 are connected together through the cooperation of the key body 201 and the keyway 103. A threaded hole 104 is provided at the end of the connecting shaft 102. The flat shaft sleeve 2 is fastened to the surface of the mounting piece 1 by a screw 3 threadably matched with the threaded hole 104. A gasket 4 is provided between the flat shaft sleeve 2 and the screw 3.

[0028] In the embodiment of the utility model, the key slot 103 is symmetrically provided on the surface of the shaft body 101, and the interior of the flat shaft sleeve 2 is provided with an axial hole along its extension direction. The end surface of the flat shaft sleeve 2 is symmetrically provided with a key body 201 adapted to the key slot 103 at the position of the axial hole. The connecting shaft 102 of the mounting member 1 passes through the axial hole of the flat shaft sleeve 2 and the flat shaft sleeve 2 is sleeved on the outer surface of the connecting shaft 102 through the cooperation of the key slot 103 and the key body 201. The cooperation of the key slot 103 and the key body 201 can not only ensure that the mounting member 1 can smoothly drive the flat shaft sleeve 2 to move in the same direction as it when it moves, but also ensure that the flat shaft sleeve 2 is aligned and connected with the mounting member 1 in the correct posture when the flat shaft sleeve 2 is replaced;

[0029] Specifically, the relative positions of the mounting member 1 and the flat shaft sleeve 2 are determined by the cooperation between the keyway 103 and the key body 201. Therefore, when replacing the flat shaft sleeve 2, it is only necessary to align the key body 201 of the flat shaft sleeve 2 with the keyway 103 of the mounting member 1, so that the flat shaft sleeve 2 can be reconnected to the mounting member 1 in the correct posture adapted to the relevant equipment, avoiding the need to adjust the overall posture of the flat shaft for a long time after replacing the flat shaft sleeve 2, reducing repair time, improving the working efficiency of the equipment, and further ensuring the reliability and stability of the product.

[0030] In the embodiment of the utility model, a flat key groove 103 is provided on the surface of one end of the shaft body 101 away from the flat shaft sleeve 2, and the mounting member 1 can be mounted on the corresponding position of the YJ27 filter tip mounting machine by the cooperation between the flat key and the flat key groove 103;

[0031] In the embodiment described in the present utility model, a threaded hole 104 is provided at the end of the connecting shaft 102 toward the direction of the shaft body 101. When the flat shaft sleeve 2 is sleeved on the outer surface of the connecting shaft 102, a screw 3 is used to sequentially penetrate the gasket 4, the shaft hole of the flat shaft sleeve 2 and the threaded hole 104, and the flat shaft sleeve 2 is fastened to the outer surface of the connecting shaft 102 through the threaded cooperation between the screw 3 and the threaded hole 104, so as to prevent the flat shaft sleeve 2 from detaching from the surface of the connecting shaft 102 when the mounting member 1 drives the flat shaft sleeve 2 to move.

[0032] In the embodiment of the present invention, the screw 3 is a hexagon socket head screw, and the screw 3 is threadedly connected to the threaded hole 104 opened at the end of the connecting shaft 102 by twisting the head end of the screw 3.

[0033] In the embodiment of the utility model, the flat shaft sleeve 2 can be provided with several models, and the difference between each model of the flat shaft sleeve 2 is that the center distance between the two glue grooves 5 provided on the surface of the flat shaft sleeve 2 is different; each time when the tipping paper with different pre-punched positions in the equipment is replaced, it is only necessary to replace the flat shaft sleeve 2 adapted to the tipping paper. In the actual operation process, the time for each replacement of the flat shaft sleeve 2 is saved from the previous 45 minutes to about 5 minutes.

[0034] In combination with the above content, the working principle of the utility model is:

[0035] First, the mounting member 1 is mounted on the corresponding position of the YJ27 filter tip assembling machine by means of the cooperation of the flat key and the flat keyway 103 to determine the relative position of the mounting member 1 and the relevant equipment. Subsequently, the connecting shaft 102 of the mounting member 1 is made to pass through the axial hole of the flat shaft sleeve 2, and the flat shaft sleeve 2 is moved on the outer surface of the connecting shaft 102 in the direction of the shaft body 101 of the mounting member 1 until the key body 201 of the flat shaft sleeve 2 is aligned with the keyway 103 of the mounting member 1, that is, the flat shaft sleeve 2 can be connected to the mounting member 1 in a correct posture adapted to the relevant equipment, so that the flat shaft sleeve 2 is sleeved on the outer surface of the connecting shaft 102. Finally, the screw 3 is used to successively pass through the gasket 4, the axial hole of the flat shaft sleeve 2 and the threaded hole 104, and the flat shaft sleeve 2 is fastened to the outer surface of the connecting shaft 102 through the thread cooperation of the screw 3 and the threaded hole 104, so as to complete the installation process created by the present invention.

[0036] When replacing the tipping paper with different pre-punched holes in the device, it is only necessary to replace the flat shaft sleeve 2 that matches the tipping paper. When replacing the flat shaft sleeve 2, repeat the above installation steps of the flat shaft sleeve 2.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
