Description

Technical Field

[0001] The invention belongs to the technical field of paper tube rolling, and particularly relates to a sloped rolling rod for rolling paper tubes. Background Art

[0002] The cigarette filter rod is the main component of the cigarette, and its function is to filter the smoke and reduce the harmful components in the smoke. Ordinary cigarette filter rods are mainly composed of forming paper, tow, and overlapping glue. The forming paper is processed from wood pulp and formed with auxiliary materials. The tow is acetate fiber tow and propylene fiber tow. In recent years, polylactic acid fiber tow has also been used as the filter rod tow, and the tow is wrapped in the forming paper to form a filter rod.

[0003] The heated cigarettes currently developed by the tobacco industry are new tobacco products that use a special heat source to heat tobacco materials (below 500°C or even lower), and the tobacco materials are only heated but not burned. They are characterized by low release of harmful ingredients and provide consumers with a certain tobacco characteristic experience. Due to the particularity of heated but not burned tobacco, its requirements for filter rods are different from those of conventional tobacco. At present, the industry has widely used paper tubes for heated cigarette composite filter rods. Since the paper tube is tightly attached to the rolling rod after rolling, it is difficult to separate the paper tube and it is inconvenient to remove it. Summary of the Invention

[0004] The purpose of the present invention is to provide a sloped rolling rod for rolling paper tubes, which uses a push platform to squeeze the fan-shaped strips on the inclined T-shaped clips of the main shaft through the extension and contraction of the telescopic hydraulic cylinder, so that the outer circumferences of multiple fan-shaped strips are cocircular and cylindrical, so that the forming paper is rolled into a cylindrical shape by the rolling rod, and after the telescopic hydraulic cylinder is contracted, the fan-shaped strips shrink inward under the action of the elastic element, so that the diameter of the rolling rod becomes smaller, so that the paper tube wrapped on the rolling rod can be easily removed.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0006] A sloped rolling rod for rolling paper tubes comprises a main shaft and a motor, wherein the main shaft is a conical structure with one end larger than the other end, and a plurality of T-shaped clips are evenly arranged axially on the outer wall of the main shaft, and a fan-shaped strip is sleeved on the T-shaped clip. The outer circumferences of the plurality of fan-shaped strips are cocircular, and a gap is left between two adjacent fan-shaped strips, and a T-shaped slot is opened axially on the fan-shaped strip. The T-shaped clip and the T-shaped slot are gradually inclined inward along the outer wall of the main shaft, and the fan-shaped strip is sleeved on the T-shaped clip through the T-shaped slot. A fixed platform and a push platform are respectively provided at both ends of the main shaft, and a connecting rod is also integrally formed at one end of the main shaft, and the connecting rod is slidably connected to the push platform, and the connecting rod is fixedly connected to the output shaft of the motor, an elastic component is installed between the fixed platform and the fan-shaped strip, and a pushing sleeve is rotatably installed on the pushing platform, and the pushing sleeve is connected to a telescopic hydraulic cylinder.

[0007] It is further defined that the push platform is provided with a through hole, the connecting rod is passed through the through hole, the connecting rod is also provided with a slide groove, the push platform is axially integrally formed with a plurality of ridges on the inner wall of the through hole, and the ridges are clamped in the slide groove. Such a structural design completes the sliding connection between the connecting rod and the push platform through the cooperation between the ridges and the slide groove, which has a simple structure and is easy to install.

[0008] The invention further defines a first stepped hole defined on the side of the sector bar proximate the fixed platform, wherein the central axis of the first stepped hole is parallel to the outer contour of the main shaft, and the elastic member comprises a plurality of guide rods fixedly mounted on the fixed platform and a compression spring sleeved on the guide rods, wherein the central axis of the guide rods coincides with the central axis of the first stepped hole, the free ends of the guide rods pass through the ends of the first stepped hole, and the compression spring is located within the first stepped hole. This structural design achieves relative positioning between the fixed platform and the sector bar by having the free ends of the guide rods pass through the ends of the first stepped hole, thereby avoiding the problem of compression spring displacement during installation of the fixed platform.

[0009] The invention further defines that the spindle has a hexagonal boss integrally formed on one end near the positioning platform, the hexagonal boss has a threaded blind hole, the fixing platform has a hexagonal blind hole, the hexagonal boss is inserted into the hexagonal blind hole, and the fixing platform further has a second stepped hole on its outer side, the second stepped hole is connected to the hexagonal blind hole, a fixing bolt is inserted into the second stepped hole, and the fixing bolt is screwed into the threaded blind hole. This structural design, through the mutual matching of the hexagonal boss and the hexagonal blind hole, cooperates with the fixing bolt to ensure that the central axis of the first stepped hole and the central axis of the guide rod remain aligned, and the loosening of the fixing bolt will not cause the central axis of the first stepped hole and the central axis of the guide rod to deviate from each other, thereby affecting the sliding of the fan-shaped bar.

[0010] Furthermore, a rotary bearing is installed between the push platform and the push sleeve. Such a structural design realizes the rotation connection between the push platform and the push sleeve through the rotary bearing, which can reduce the friction between the push platform and the push sleeve and extend the service life.

[0011] Further defined, a positioning bracket is provided on the outer side of the push platform, a sliding rod is fixedly mounted on the positioning bracket, and a support ear is fixedly mounted on the push sleeve, and the support ear is mounted on the sliding rod. This structural design, through the interaction between the support ear and the sliding rod, can prevent the main shaft from rotating under the action of the motor, which in turn drives the push sleeve to rotate, thereby applying torque to the telescopic hydraulic cylinder and causing damage to the telescopic hydraulic cylinder.

[0012] A sliding bearing is mounted within the lug, which is sleeved onto the sliding rod. This structural design replaces the sliding friction between the lug and the sliding rod with rolling friction between the sliding bearing and the sliding rod, thereby reducing friction, making the movement of the second hydraulic cylinder smoother, and extending the service life of the lug and the sliding rod.

[0013] The invention adopting the above technical solution has the following advantages:

[0014] 1. Through the extension and retraction of the telescopic hydraulic cylinder, the push platform squeezes the sector strips mounted on the inclined T-shaped clamping strip of the main shaft, so that the outer circumferences of the multiple sector strips are cocircular and cylindrical, and the forming paper is rolled into a cylindrical shape by the rolling rod. After the telescopic hydraulic cylinder is retracted, the sector strips shrink inward under the action of the elastic element, making the diameter of the rolling rod smaller, so that the paper tube wrapped on the rolling rod can be easily removed;

[0015] 2. The free end of the guide rod is inserted into the end of the first stepped hole to complete the mutual positioning between the fixed platform and the sector bar, avoiding the problem of compression spring deviation when installing the fixed platform;

[0016] 3. By matching the hexagonal boss and the hexagonal blind hole with each other and cooperating with the fixing bolts, it can be ensured that the central axis of the first stepped hole and the central axis of the guide rod remain coincident, and the central axis of the first stepped hole and the central axis of the guide rod will not be offset from each other due to the loosening of the fixing bolts, thereby affecting the sliding of the fan-shaped bar.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions, similar or identical parts are numbered the same. Implementations not shown or described in the drawings are forms known to those of ordinary skill in the art. In addition, directional terms mentioned in the embodiments, such as "upper," "lower," "top," "bottom," "left," "right," "front," and "back," are merely references to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0032] like Figures 1 to 7 As shown, the present invention provides a sloped rolling rod for paper tube rolling, comprising a main shaft 1 and a motor 3. The main shaft 1 is a conical structure with one end larger than the other end. Four T-shaped clips 11 are evenly arranged axially on the outer wall of the main shaft 1. A fan-shaped strip 2 is sleeved on the T-shaped clip 11. The outer circumferences of the four fan-shaped strips 2 are cocircular, and a gap is left between two adjacent fan-shaped strips 2. The fan-shaped strips 2 are axially provided with a T-shaped slot 21. The T-shaped clips 11 and the T-shaped slots 21 are gradually extended inward along the outer wall of the main shaft 1. Tilt, the fan-shaped bar 2 is sleeved on the T-shaped clip 11 through the T-shaped slot 21, and a fixed platform 31 and a push platform 32 are respectively provided at both ends of the main shaft 1. A connecting rod 33 is also integrally formed at one end of the main shaft 1. The connecting rod 33 is slidably connected to the push platform 32, and the connecting rod 33 is fixedly connected to the output shaft of the motor 3. An elastic component is installed between the fixed platform 31 and the fan-shaped bar 2, and a pushing sleeve 321 is rotatably installed on the push platform 32, and the pushing sleeve 321 is connected to a telescopic hydraulic cylinder 322.

[0033] The push platform 32 is provided with a through hole 320, the connecting rod 33 is passed through the through hole 320, and the connecting rod 33 is also provided with a slide groove 330. The push platform 32 is integrally formed with a plurality of ribs 3201 on the inner wall of the through hole 320, and the ribs 3201 are clamped in the slide groove 330. The ribs 3201 cooperate with the slide groove 330 to complete the sliding connection between the connecting rod 33 and the push platform 32. The structure is simple and the installation is convenient.

[0034] A first stepped hole 311 is defined on the side of the sector bar 2 near the fixing platform 31. The central axis of the first stepped hole 311 is parallel to the outer contour of the main shaft 1. The elastic member comprises a plurality of guide rods 312 fixedly mounted on the fixing platform 31 and a compression spring 313 sleeved on the guide rods 312. The central axis of the guide rods 312 coincides with the central axis of the first stepped hole 311. The free ends of the guide rods 312 extend through the ends of the first stepped hole 311, and the compression spring 313 is positioned within the first stepped hole 311. By having the free ends of the guide rods 312 extend through the ends of the first stepped hole 311, the fixing platform 31 and the sector bar 2 are positioned relative to each other, preventing the compression spring from shifting during installation of the fixing platform 31.

[0035] A hexagonal boss 12 is integrally formed at one end of the spindle 1 near the positioning platform. A threaded blind hole 120 is formed on the hexagonal boss 12. A hexagonal blind hole 34 is formed on the fixing platform 31. The hexagonal boss 12 is inserted into the hexagonal blind hole 34. A second stepped hole 35 is also formed on the outer side of the fixing platform 31. The second stepped hole 35 is connected to the hexagonal blind hole 34. A fixing bolt is inserted into the second stepped hole 35 and screwed into the threaded blind hole 120. The mutual matching of the hexagonal boss 12 and the hexagonal blind hole 34, in conjunction with the fixing bolt, ensures that the central axis of the first stepped hole 311 and the central axis of the guide rod 312 remain aligned. Loosening of the fixing bolt will prevent the central axis of the first stepped hole 311 and the central axis of the guide rod 312 from offsetting each other, thereby affecting the sliding of the sector bar 2.

[0036] A rotating bearing 310 is installed between the push platform 32 and the pushing sleeve 321. The rotating bearing 310 realizes the rotation connection between the push platform 32 and the pushing sleeve 321, which can reduce the friction between the push platform 32 and the pushing sleeve 321 and extend the service life.

[0037] A positioning bracket 323 is provided on the outside of the push platform 32. A sliding rod 324 is fixedly mounted on the positioning bracket 323. A support ear 325 is fixedly mounted on the push sleeve 321. The support ear 325 is sleeved on the sliding rod 324. The interaction between the support ear 325 and the sliding rod 324 prevents the main shaft 1 from rotating under the action of the motor 3, which in turn drives the push sleeve 321 to rotate, thereby applying torque to the telescopic hydraulic cylinder 322 and causing damage to the telescopic hydraulic cylinder 322.

[0038] A sliding bearing is installed in the lug 325, and the sliding bearing is sleeved on the sliding rod 324. The rolling friction between the sliding bearing and the sliding rod 324 replaces the sliding friction between the lug 325 and the sliding rod 324, thereby reducing friction, making the movement of the second hydraulic cylinder 322 smoother, and also extending the service life of the lug 325 and the sliding rod 324.

[0039] In this embodiment, when rolling, the telescopic hydraulic cylinder 322 is controlled to extend, driving the push platform 32 to move to the left, and the side wall on the left side of the push platform 32 is used to push the sector bar 2 to the left, so that the sector bar 2 overcomes the prestress of the compression spring 313 and moves to the left along the inclined T-shaped clamping strip 11, and expands outward until the left end face of the sector bar 2 abuts against the right end face of the fixed platform 31. At this time, the outer circumferences of the multiple sector bars 2 are cocircular and cylindrical. Then, the forming paper is attached to the sector bar 2, and the motor 3 is started. The motor 3 can drive the main shaft 1 and the sector bar 2 to rotate, thereby rolling the forming paper into a paper tube;

[0040] After the rolling is completed, when the paper tube needs to be removed from the rolling rod, the telescopic hydraulic cylinder 322 is controlled to retract, causing the push platform 32 to move to the right. At this time, the fan-shaped bar 2 moves along the inclined T-shaped clamping bar 11 under the action of the compression spring 313 and retracts inward, thereby achieving the purpose of reducing the overall diameter of the rolling rod. At this time, the paper tube can be easily removed from the rolling rod;

[0041] When rolling next time, just control the telescopic hydraulic cylinder 322 to extend again.

[0042] The above describes in detail the sloped rolling rod for rolling paper tubes provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the method and core concepts of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims of the present invention.
