Description

Technical Field

[0001] This utility model belongs to the field of assembly machine technology, specifically relating to an assembly machine starter rail. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] The gap between the starting end of the tipping machine's starting rail and the splicing drum is fixed and smaller than the gap between the rubbing plate and the splicing drum. The main function of the starting end is to exert pressure on the combined cigarettes with the tipping paper attached through interaction with the splicing drum, thereby removing them from the splicing drum and placing them between the rubbing plate and the splicing drum. Utilizing the self-rolling of the combined cigarettes, the cigarettes with the tipping paper attached are spliced ​​into double-length cigarettes. To achieve large-scale production of menthol capsule cigarettes, cigarette companies often adjust existing production lines, but the core tipping machine splicing system still uses a traditional design.

[0004] The starting rail of a traditional cigarette-filling machine is a key component of the splicing system. Its starting end has a fixed gap with the splicing drum, smaller than the gap between the splicing plate and the drum. When producing regular cigarettes without flavor capsules, this design stably compresses the cigarette, completing the tipping paper wrapping and ensuring smooth production. However, when producing cigarettes with flavor capsules at the filter tip, the fixed gap design of the traditional starting rail presents problems. Some flavor capsules need to be designed to be larger to improve flavor. When a cigarette containing a large-diameter flavor capsule passes through the gap between the starting rail and the drum, the capsule directly bears the compression pressure from both. Because the gap cannot be adaptively adjusted, the larger the diameter of the flavor capsule, the stronger the pressure, far exceeding the pressure resistance of the capsule shell, making the capsule extremely prone to breakage. A broken flavor capsule not only renders the individual cigarette unusable but may also contaminate subsequent cigarettes, posing a quality hazard. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a starting rail for a connector machine. When the pressure on the mouthpiece end of the bursting bead is too high, the retractable starting end corresponding to the position of the mouthpiece end bursting bead can move downward to work, thereby reducing the pressure on the mouthpiece end bursting bead, alleviating the degree of compression on the bursting bead, and avoiding the problem of the mouthpiece end bursting bead breaking.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A starting rail for a machine assembly includes a starting rail body and a starting block. The upper part of the starting rail body has a groove, and the groove has a first longitudinal positioning hole and a second longitudinal positioning hole. The lower end of the starting block has a cylindrical component, and both ends of the cylindrical component have internally threaded hollow tubes. The cylindrical component is located within the first longitudinal positioning hole, and a spring is sleeved on the cylindrical component. The internally threaded hollow tubes are located within the second longitudinal positioning hole. Bolts are installed at intervals at the lower end of the second longitudinal positioning hole, and the bolts are threadedly connected to the internally threaded hollow tubes.

[0007] As a further technical solution, the depth of the first longitudinal positioning hole is less than the depth of the second longitudinal positioning hole, the spring is located inside the first longitudinal positioning hole, and the cylindrical component is used to define the position of the spring.

[0008] As a further technical solution, the second longitudinal positioning hole is disposed at both ends of the first longitudinal positioning hole, and the second longitudinal positioning hole penetrates the starter rail body.

[0009] As a further technical solution, the internally threaded hollow tube is located at the upper end inside the second longitudinal positioning hole, and the internal thread is provided on the inner wall surface of the internally threaded hollow tube.

[0010] As a further technical solution, the bolts are spaced several times apart.

[0011] As a further technical solution, an elastic washer is fitted on the bolt, and the elastic washer is in close contact with the lower surface of the starting rail body.

[0012] As a further technical solution, the side of the starting rail body is provided with transverse positioning holes, and several transverse positioning holes are provided at intervals. The transverse positioning holes are used to install the receiving machine starting rail on the receiving machine washboard.

[0013] As a further technical solution, the cylindrical component is fixedly connected to the starting block, and the internally threaded hollow tube is fixedly connected to the starting block.

[0014] As a further technical solution, the shape of the starting block is the same as the shape of the upper end of the starting rail body.

[0015] As a further technical solution, there is a gap between the starting block and the groove.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are: This invention, when the pressure on the flavor capsule increases due to the starting rail and the twisting drum, pushes the starting block downwards, compressing the spring on the cylindrical component. This widens the local gap, reducing the pressure on the flavor capsule and preventing it from rupturing due to excessive compression. It also avoids machine shutdowns caused by clogging of the twisting plate. During the twisting process, the filter tip at the flavor capsule location remains under pressure from the starting block and the twisting drum, ensuring twisting quality and preventing defects such as poor twisting of the cigarette splice paper.

[0019] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0020] The starting rail of a traditional cigarette-filling machine is a key component of the splicing system. Its starting end has a fixed gap with the splicing drum, smaller than the gap between the splicing plate and the drum. When producing regular cigarettes without flavor capsules, this design stably compresses the cigarette, completing the tipping paper wrapping and ensuring smooth production. However, when producing cigarettes with flavor capsules at the filter tip, the fixed gap design of the traditional starting rail presents problems. Some flavor capsules need to be designed to be larger to improve flavor. When a cigarette containing a large-diameter flavor capsule passes through the gap between the starting rail and the drum, the capsule directly bears the compression pressure from both. Because the gap cannot be adaptively adjusted, the larger the diameter of the flavor capsule, the stronger the pressure, far exceeding the pressure resistance of the capsule shell, making the capsule extremely prone to breakage. A broken flavor capsule not only renders the individual cigarette unusable but may also contaminate subsequent cigarettes, posing a quality hazard.

[0021] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a mounting rail for a machine, such as... Figure 1 As shown, the device includes a starter rail body 1 and a starter block 2. The upper part of the starter rail body 1 is provided with a groove 3, and the groove 3 is provided with a first longitudinal positioning hole 12 and a second longitudinal positioning hole 5. The lower end of the starter block 2 is provided with a cylindrical part 8, and both ends of the cylindrical part 8 are provided with internally threaded hollow tubes 7. The cylindrical part 8 is located in the first longitudinal positioning hole 12, and a spring 11 is sleeved on the cylindrical part 8. The internally threaded hollow tube 7 is located in the second longitudinal positioning hole 5. Bolts 9 are installed at the lower end inside the second longitudinal positioning hole 5, and several bolts 9 are arranged at intervals. The bolts 9 are threadedly connected to the internally threaded hollow tube 7.

[0022] Specifically, when the pressure on the flavor capsule increases due to the starting rail and the twisting drum, it pushes the starting block 2 downward, compressing the spring 11 on the cylindrical part 8. This expands the local gap 4, reducing the squeezing pressure on the flavor capsule and preventing it from rupturing due to excessive squeezing. It also avoids machine shutdowns caused by clogging of the twisting plate. During the twisting process, the filter tip at the flavor capsule position is still subjected to pressure from the starting block 2 and the twisting drum, ensuring the twisting quality and avoiding quality defects such as poor twisting of the cigarette splice paper.

[0023] The depth of the first longitudinal positioning hole 12 is less than the depth of the second longitudinal positioning hole 5. The spring 11 is located inside the first longitudinal positioning hole 12, and the cylindrical part 8 is used to limit the position of the spring 11.

[0024] Specifically, such as Figure 3 , Figure 4 as well as Figure 5As shown, a first longitudinal positioning hole 12 for accommodating a spring 11 is formed downward on the upper end face of the starter rail body 1. At the same time, second longitudinal positioning holes 5 are formed at the left and right ends of the first longitudinal positioning hole 12. The first longitudinal positioning hole 12 extends only into the interior of the starter rail body 1 and does not penetrate the starter rail body 1, while the second longitudinal positioning holes 5 penetrate from the upper end face to the lower end face of the starter rail body 1, forming a through channel.

[0025] During assembly, the spring 11 is placed into the first longitudinal positioning hole 12 as a whole, and then one end of the cylindrical part 8 is inserted into the center of the spring 11. The outer wall of the cylindrical part 8 fits against the inner wall of the first longitudinal positioning hole 12. Through the limiting effect of the cylindrical part 8, the spring 11 is prevented from shifting during compression or rebound, ensuring that the spring 11 always extends and retracts along the axial direction of the first longitudinal positioning hole 12.

[0026] like Figure 6 As shown, the second longitudinal positioning hole 5 is located at both ends of the first longitudinal positioning hole 12, and the second longitudinal positioning hole 5 penetrates the starter rail body 1.

[0027] Specifically, a hollow tube 7 with internal threads is fixedly installed inside the second longitudinal positioning hole 5 near the upper end. The outer wall of the hollow tube 7 with internal threads fits tightly with the inner wall of the second longitudinal positioning hole 5, and the inner wall of the hollow tube 7 with internal threads is machined with a continuous internal thread structure for mating with the bolt 9.

[0028] Insert the bolt 9 from top to bottom into the second longitudinal positioning hole 5 from the lower end face of the starting rail body 1, so that the external thread of the bolt 9 meshes with the internal thread of the internal thread hollow tube 7. The upper and lower positions of the bolt 9 within the second longitudinal positioning hole 5 can be adjusted by rotating the bolt 9. At the same time, an elastic washer 10 is fitted between the head of the bolt 9 and the lower end face of the starting rail body 1. One side of the elastic washer 10 is in close contact with the head of the bolt 9, and the other side is completely in contact with the lower surface of the starting rail body 1. The elastic washer 10 enhances the stability of the bolt 9 connection and prevents the bolt 9 from loosening due to vibration during equipment operation.

[0029] The internally threaded hollow tube 7 is located at the upper end inside the second longitudinal positioning hole 5, and internal threads are provided on the inner wall surface of the internally threaded hollow tube 7. Bolts 9 are installed at the lower end inside the second longitudinal positioning hole 5, and several bolts 9 are spaced apart. The bolts 9 are threadedly connected to the internally threaded hollow tube 7.

[0030] An elastic washer 10 is fitted onto the bolt 9, and the elastic washer 10 is in close contact with the lower surface of the starting rail body 1. Specifically, the bolt 9 and the bottom of the starting rail body 1 have an elastic washer 10, which is used to reduce the vibration of the starting block 2 during operation and plays a protective role.

[0031] The side of the starting rail body 1 is provided with transverse positioning holes 6. Several transverse positioning holes 6 are provided at intervals. The transverse positioning holes 6 are used to install the starting rail of the receiving machine onto the receiving machine's washboard.

[0032] Specifically, several horizontal positioning holes 6 are evenly opened on the side of the starter rail body 1 along the horizontal direction. The horizontal positioning holes 6 penetrate the starter rail body 1, and the axes of all the horizontal positioning holes 6 are at the same horizontal height. When it is necessary to install the starter rail onto the washboard of the assembly machine, the starter rail body 1 is placed against the preset installation position of the washboard, so that the horizontal positioning holes 6 on the starter rail body 1 are aligned with the pre-reserved installation holes on the washboard. Then, the positioning pins or bolts 9 are passed through the horizontal positioning holes 6 and the washboard installation holes to complete the fixed connection between the starter rail and the washboard.

[0033] The cylindrical component 8 is fixedly connected to the starting block 2, and the internally threaded hollow tube 7 is also fixedly connected to the starting block 2. The shape of the starting block 2 is the same as the shape of the upper end of the starting rail body 1. Figure 2 As shown, there is a gap 4 between the starting block 2 and the groove 3.

[0034] Specifically, a groove 3 matching the shape of the starting block 2 is formed on the upper end face of the starting rail body 1, and the starting block 2 is installed in the groove 3. After assembly, a certain gap 4 is reserved between the outer wall of the starting block 2 and the inner wall of the groove 3. The size of the gap 4 ensures that the starting block 2 can move up and down along the inner wall of the groove 3 when squeezed by the popping bead, ensuring the flexibility and stability of the starting block 2. When the popping bead is subjected to increased pressure from the starting rail and the rubbing drum, it will push the starting block 2 downward, and the spring 11 on the cylindrical part 8 will be compressed accordingly, thereby widening the local gap 4, reducing the squeezing pressure on the popping bead, and preventing the popping bead from being over-squeezed and breaking.

[0035] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
