Description

Technical Field

[0001] The utility model belongs to the technical field of wire making equipment, and in particular relates to a sealing row chain for a wire cutting machine. Background Art

[0002] During the production process of the shredding equipment in the cigarette shredding production line, keeping the upper and lower copper chain running smoothly is the key to ensuring the shredded quality.

[0003] During the production process of the wire cutting machine, the upper and lower copper chains move synchronously towards each other, and gaps will be generated in the chain during the movement, especially at the driving sprocket and the driven sprocket. The gap will be further increased due to wear, deformation and other reasons.

[0004] During the previous processing steps, tobacco leaves will be broken into small tobacco flakes and tobacco dust. At the current stage, there are gaps between the chains, causing small tobacco flakes and tobacco dust to enter the interior of the chains through the gaps. The accumulation over a period of time will increase the wear of the chains and seriously affect the quality of shredded tobacco. Utility Model Content

[0005] The purpose of the utility model is to provide a sealed row chain for a shredder, which can seal the gap between the side wall of the pin barrel and the base of the adjacent chain link through a sealing mechanism, thereby preventing small cigarette pieces and cigarette dust from entering the interior of the row chain from the gap between the pin barrel and the adjacent base, reducing the wear of the row chain and improving the shredding quality.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] A sealed chain for a wire cutting machine, comprising a plurality of chain links connected in sequence, wherein the chain links comprise a base body and a plurality of pin barrels arranged on both sides of the base body, and the pin barrels are provided with pin shaft holes for passing pin shafts;

[0008] The plurality of pin barrels on both sides are arranged alternately along the length direction of the base, and the pin barrels protrude from the lower surface of the base;

[0009] A sealing mechanism is fixedly provided on the side of the pin barrel away from the base body, and the side of the sealing mechanism away from the pin barrel abuts against the base body of the adjacent chain link.

[0010] It is further defined that the sealing mechanism is a sealing sleeve sleeved on the pin barrel. With such a structural design, the gap between the pin barrel and the adjacent substrate is blocked by the sealing sleeve, and the sealing effect is better.

[0011] It is further defined that the sealing mechanism is a sealing strip arranged along the axial direction of the pin barrel. Such a structural design completes the sealing of the gap between the pin barrel and the adjacent substrate through the sealing strip, has a simple structure, low cost and strong practicality.

[0012] It is further defined that the pin barrel is provided with an axial receiving groove on one side away from the base body, and the sealing strip is inserted into the receiving groove and protrudes from the side of the receiving groove. With such a structural design, the sealing strip is received by the receiving groove, and during installation, the sealing strip is positioned by the receiving groove, which can avoid dislocation of the sealing strip during installation, and is more convenient to install.

[0013] It is further defined that the width dimension of the receiving groove in the vertical direction on the side away from the pin barrel is smaller than the maximum width dimension of the receiving groove in the vertical direction. With such a structural design, after the sealing strip is inserted into the receiving groove, the width dimension difference of the receiving groove can be used to radially limit the sealing strip to prevent the sealing strip from falling out of the receiving groove. At the same time, after the sealing strip is excessively worn, it is easy to replace, and the practicability is strong.

[0014] It is further defined that the sealing strip includes a mounting strip and an outer convex strip, the mounting strip is cylindrical and located in the receiving groove, the outer convex strip is located between the mounting strip and the adjacent base, and the width of the outer convex strip in the vertical direction is greater than the width of the receiving groove away from the pin barrel in the vertical direction. Such a structural design, through the size difference between the outer convex strip and the receiving groove, prevents the outer convex strip from entering the receiving groove during the extrusion process, thereby causing the problem of loose sealing.

[0015] It is further defined that the ends of both ends of the mounting strip are provided with bosses, the diameter of the bosses is larger than the diameter of the mounting strip, and the ends of both ends of the pin barrel are provided with limiting grooves, and the bosses are located in the limiting grooves. Such a structural design, through the cooperation between the bosses and the limiting grooves, axially limits the sealing strip, and prevents the sealing strip from axially moving during use, so that the sealing strip enters between the two pin barrels, and then causes the problem of the chain link being stuck, and is highly practical; during installation, the elasticity of the sealing strip is used to pull the sealing strip toward both ends, so that the diameter of the mounting strip becomes smaller, and then the mounting strip is inserted into the receiving groove from the outside of the receiving groove, and then the pulling on the sealing strip is released, and the sealing strip is reset under the action of its own elastic force until the boss is inserted into the limiting groove.

[0016] The utility model adopting the above technical solution has the following advantages:

[0017] 1. The gap between the side wall of the pin barrel and the base of the adjacent chain link is sealed by the sealing mechanism, which can prevent small cigarette pieces and cigarette dust from entering the interior of the chain from the gap between the pin barrel and the adjacent base, reduce the wear of the chain and improve the quality of shredded wire;

[0018] 2. The sealing strip is accommodated by the accommodating groove. During installation, the sealing strip is positioned by the accommodating groove, which can avoid dislocation of the sealing strip during installation and make installation more convenient;

[0019] 3. Through the width difference of the accommodating groove, after the sealing strip is inserted into the accommodating groove, the size difference can be used to limit the radial position of the sealing strip to prevent the sealing strip from falling out of the accommodating groove. At the same time, after the sealing strip is excessively worn, it is easy to replace, which is very practical.

[0020] 4. The size difference between the outer convex strip and the receiving groove can prevent the outer convex strip from entering the receiving groove during the extrusion process, thereby causing the problem of loose sealing;

[0021] 5. The sealing strip is axially limited by the cooperation between the boss and the limiting groove to prevent the sealing strip from axially moving during use, causing the sealing strip to enter between the two pin barrels and thus causing the chain links to get stuck. It is very practical. During installation, the elasticity of the sealing strip is used to pull the sealing strip to both ends to reduce the diameter of the installation strip, and then the strip is inserted into the receiving groove from the outside of the receiving groove. After that, the pulling on the sealing strip is released, and the sealing strip is reset under the action of its own elastic force until the boss is inserted into the limiting groove.

[0031] A plurality of pin barrels 12 on both sides are arranged alternately along the length direction of the base 11, and the pin barrels 12 protrude from the lower surface of the base 11;

[0032] A sealing mechanism is fixedly provided on the side of the pin barrel 12 away from the base body 11 , and the side of the sealing mechanism away from the pin barrel 12 abuts against the base body 11 of the adjacent chain link 1 .

[0033] The sealing mechanism is a sealing sleeve sleeved on the pin barrel 12. The gap between the pin barrel 12 and the adjacent substrate 11 is blocked by the sealing sleeve, and the sealing effect is better.

[0034] The sealing mechanism is a sealing strip 2 arranged along the axial direction of the pin barrel 12. The sealing strip 2 is used to seal the gap between the pin barrel 12 and the adjacent substrate 11, which has a simple structure, low cost and strong practicality.

[0035] The pin barrel 12 is provided with an accommodating groove 3 axially on one side away from the base 11, and the sealing strip 2 is inserted into the accommodating groove 3, and the side surface protrudes from the accommodating groove 3. In fact, according to the actual situation, a method such as directly pasting the sealing strip 2 on the outer wall of the pin barrel 12 can be selected to achieve the installation of the sealing strip 2. In this embodiment, the sealing strip 2 is accommodated by the accommodating groove 3. During installation, the sealing strip 2 is positioned by the accommodating groove 3, which can avoid the sealing strip 2 from being misplaced during installation, and the installation is more convenient.

[0036] The width dimension of the receiving groove 3 in the vertical direction on the side away from the pin barrel 12 is smaller than the maximum width dimension of the receiving groove 3 in the vertical direction. In fact, according to the actual situation, a receiving groove 3 without a size difference can be used. In the process of placing the sealing strip 2 into the receiving groove 3, glue is used to fix the sealing strip 2. In this embodiment, the width size difference of the receiving groove 3 can be used to radially limit the sealing strip 2 after the sealing strip 2 is inserted into the receiving groove 3, so as to prevent the sealing strip 2 from falling out of the receiving groove 3.

The outer convex strip 22 is located between the mounting strip 21 and the adjacent base 11. The width of the outer convex strip 22 in the vertical direction is greater than the width of the receiving groove 3 away from the pin barrel 12 in the vertical direction. In fact, according to actual conditions, a sealing strip 2 with an inclined I-shaped cross section can be directly selected. In this embodiment, the size difference between the outer convex strip 22 and the receiving groove 3 is used to prevent the outer convex strip 22 from entering the receiving groove 3 during the extrusion process, thereby causing the problem of loose sealing.

[0038] The ends of both ends of the mounting strip 21 are provided with bosses 23, the diameter of the bosses 23 is larger than the diameter of the mounting strip 21, and the ends of both ends of the pin barrel 12 are provided with limiting grooves 230, and the bosses 23 are located in the limiting grooves 230. Through the cooperation between the bosses 23 and the limiting grooves 230, the sealing strip 2 is axially limited to prevent the sealing strip 2 from axial movement during use, so that the sealing strip 2 enters between the two pin barrels 12, and then causes the problem of the chain link 1 being stuck, which is highly practical; during installation, the elasticity of the sealing strip 2 is used to pull the sealing strip 2 to both ends, so that the diameter of the mounting strip 21 becomes smaller, and then the mounting strip 21 is inserted into the receiving groove 3 from the outside of the receiving groove 3, and then the pulling of the sealing strip 2 is released, and the sealing strip 2 is reset under the action of its own elastic force until the boss 23 is inserted into the limiting groove 230.
