Description

Technical Field

[0001] The present invention relates to the technical field of devices requiring paper tubes, such as beverage paper straws or heat-not-burn cigarettes, and more particularly to a composite double-layer straight hollow paper tube manufacturing device and a composite double-layer straight hollow paper tube manufacturing method. Background Art

[0002] Currently, paper tubes for beverage straws and heat-not-burn cigarettes are typically manufactured using a radial spiral winding method. Multiple strips of glued paper are continuously bent at a fixed angle by a flat belt around a fixed steel shaft. The spirals are then formed into continuous spiral tubes, which are then cut into desired lengths by a reciprocating cutting mechanism with multiple circular knives.

[0003] The existing radial spiral wound paper tube has the following disadvantages due to the forming principle:

[0004] First, the speed is slow: Spirals are slower than straight lines and have greater winding resistance, which prevents high-speed production. Furthermore, the angle and tightness of the formed spiral paper tubes affect the stability of the output speed. Therefore, the spiral paper tubes can only be cut synchronously using multiple circular knife reciprocating cutting devices. However, the large inertia of multiple circular knife reciprocating cutting devices further limits the speed.

[0005] Second, the amount of material and adhesive used is high: To ensure the strength of the paper tube, spiral paper tubes typically use multiple layers of thickened paper tape, which consumes a large amount of material. The spiral paper tube's output speed is unstable, and the multiple circular knife reciprocating cutting devices, in order to ensure that each section of the spiral paper tube is cut to a consistent length, waste an extra section of the spiral paper tube with each cut. Because the spiral is wound, the paper tape must be glued all over to ensure that the edges do not curl, which also requires a large amount of adhesive.

[0006] Third, the device is complex and has poor stability: The multiple circular blade reciprocating cutting device is bulky and heavy, complex to install, and has a large moment of inertia. During spiral winding, the flat belt bends the glued paper tape into the steel shaft surface. The flat belt's winding angle radius is very small, resulting in a short service life, uneven linear speed, and poor stability.

[0007] Fourth, food safety is poor and the paper tube quality is low: Although the glue used in spiral paper tubes is non-toxic, excessive contact with it can still be harmful to the human body. The central paper strip, when spirally bent, is glued on both sides, requiring a large amount of glue. This also causes some glue to overflow from the edges of the strip, leaving a large amount of glue residue on both the inner and outer surfaces of the spiral paper tube, compromising food safety. Furthermore, the spiral molding results in a rough surface and uneven thickness, resulting in poor quality paper tubes. Summary of the Invention

[0049] Optional, such as Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 、 Figures 12 to 15 As shown, in some embodiments, it also includes a fixed steel shaft 35 and a fixed steel shaft bracket 14. The fixed steel shaft bracket 14 is installed on the bracket 37. The fixed steel shaft bracket 14 is installed with the fixed steel shaft 35.

The inner layer paper tape forming mechanism, the outer layer paper tape forming mechanism and the compound mechanism are sequentially sleeved on the fixed steel shaft 35. The other end of the fixed steel shaft 35 is in contact with the cutting mechanism.

[0050] In the above optional embodiment, it should be noted that the shape of the fixed steel shaft 35 is cylindrical, and the surface of the fixed steel shaft 35 is treated with ceramic surface treatment to reduce friction and increase service life.

[0051] Optional, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, in some embodiments, the inner paper tape forming mechanism includes an inner paper tape forming guide rail 15, an inner linear paper tube traction wheel torque clutch 16 and an inner linear paper tube traction wheel 17. The inner linear paper tube traction wheel torque clutch 16 is provided with an inner linear paper tube traction wheel 17. A fixed steel shaft 35 is inserted into the inner paper tape forming guide rail 15. The inner paper tape 10 cooperates with the fixed steel shaft 35 and the inner paper tape forming guide rail 15 to form an inner linear paper tube 18.

[0052] The beneficial effects of the above optional embodiments are: the inner paper tape 10 is formed into an inner linear paper tube 18 by setting the inner paper tape forming guide rail 15, and the inner linear paper tube traction wheel torque clutch 16 ensures that the rotation speed of the inner linear paper tube traction wheel 17 is maintained at a constant speed.

[0053] In the above optional embodiment, it should be noted that the inner layer straight paper tube 18 is formed in the following manner: the inner layer paper unwinder 9 unwinds the inner layer paper tape 10 at a constant torque, and then the inner layer paper tape feeding wheel pulls out the inner layer paper tape 10 at a constant linear speed. After the inner layer paper tape 10 is pulled out, it is guided by the inner layer paper tape steering wheel 11 and passes over the fixed steel shaft 35. The center of the inner layer paper tape 10 is aligned with the upper surface of the fixed steel shaft 35, and then the inner layer paper tape is formed by the inner layer paper tape forming guide rail 15 to form the inner layer straight paper tube 18. In addition, the inner layer The paper tape forming guide 15 is a split type, formed by the combination of two semi-circular cones. The center hole of the inner paper tape forming guide 15 is a conical hole. The conical hole in the center of the inner paper tape forming guide 15 is used to gradually collect the inner paper tape 10 and attach it to the surface of the fixed steel shaft 35 to form an inner straight paper tube 18 with the opening downward. The inner straight paper tube traction wheel 17 uses the tension provided by the inner straight paper tube traction wheel torque clutch 16 to tighten and pull the inner straight paper tube 18 forward, and slide it along the fixed steel shaft 35 to transport it to the composite mechanism.

[0054] Optional, such as Figure 1 、 Figure 2 、 Figure 7 and Figure 9 As shown, in some embodiments, the outer paper tape forming mechanism includes an outer paper tape forming guide rail 21, on which a fixed steel shaft 35 is inserted. The outer paper tape 5 cooperates with the fixed steel shaft 35 and the outer paper tape forming guide rail 21 to form an outer linear paper tube 22.

[0055] The beneficial effect of the above optional embodiment is that the outer paper tape 5 is formed into an outer linear paper tube 22 by the provision of the outer paper tape forming guide rail 21 .

[0056] In the above optional embodiment, it should be noted that the outer layer straight paper tube 22 is formed in such a way that the outer layer paper reel 2 unwinds the outer layer paper tape 10 at a constant torque, and then the outer layer paper tape paper feeding wheel 3 pulls out the outer layer paper tape 5 at a constant linear speed. After the outer layer paper tape 5 is pulled out, it is guided by the outer layer paper tape steering wheel 7 and passes under the fixed steel shaft 35. The center of the outer layer paper tape 5 is aligned with the lower surface of the fixed steel shaft 35 and is formed by the outer layer paper tape forming guide rail 21. The outer paper tape forming guide rail 21 is arranged behind the inner linear paper tube traction wheel 17. The outer paper tape forming guide rail 21 is a split type, formed by a combination of two semi-circular cones. The center hole of the outer paper tape forming guide rail 21 is a conical hole. The outer paper tape 5 is gradually disturbed when passing through and adheres to the surface of the inner linear paper tube 18 to form an outer linear paper tube 24 with an opening facing upward. Then, multiple pairs of main traction wheels 26 use the tension provided by the main traction wheel torque clutch 25 to synchronously tighten and pull the paper tube along the fixed steel shaft 35 to slide and transport it to the composite mechanism.

One end of the combined guide rail 20 is connected to the outer paper tape forming guide rail 21 and the inner paper tape forming guide rail 15 through a fixed steel shaft 35. The other end of the combined guide rail 20 is connected to the semicircular groove soldering iron 23 through a fixed steel shaft 35. The inner linear paper tube 18 and the outer linear paper tube 22 cooperate with each other through the combined guide rail 20 and the semicircular groove soldering iron 23 to form a double-layer linear paper tube 24.

[0058] The beneficial effect of the above optional embodiment is: by setting the combined guide rail 20, the inner linear paper tube 18 and the outer linear paper tube 22 are combined to form a double-layer linear paper tube 24, and then the semicircular groove soldering iron 23 makes the double-layer linear paper tube 24 more firm.

[0059] In the above-mentioned optional embodiment, it should be noted that the inner linear paper tube 18 is guided into the outer linear paper tube 22 by the combined guide rail 20. The combined guide rail 20 is a semi-cylindrical opening, with the opening aligned downwardly with the fixed steel shaft 35. The outer surface at the exit is guided into a conical shape and can be disassembled. When the inner linear paper tube 18 enters the combined guide rail 20, the inner linear paper tube is supported on both sides of the lower opening by the inner linear paper tube bracket 19 and enters the outer paper tape 5. During operation, the inner linear paper tube 18 remains in a tubular shape and does not fall apart. The outer paper tape 5 is formed by the outer paper tape forming guide rail 21 and attached to the surface of the inner linear paper tube 18, forming the outer linear paper tube 22 with an upward opening. The inner linear paper tube 18 and the outer linear paper tube 22 are then combined. The resulting double-layer linear paper tube is reinforced by the provision of a semi-circular groove soldering iron 23. In addition, the semi-circular groove soldering iron 23 consists of an upper soldering iron and a lower soldering iron, which can be flipped up and down while maintaining a certain elastic force. When parking, flipping the double-layer straight paper tube 24 upward and downward effectively prevents scorching. During operation, the upper and lower semicircular grooves of the semicircular groove soldering iron 23 form a circular open working chamber, which maintains a certain elastic pressure on the glued outer straight paper tube 22 and inner straight paper tube 18, pressing them onto the fixed steel shaft 35. The high-temperature semicircular groove soldering iron 23 dries and bonds the glued outer straight paper tube 22 and inner straight paper tube 18, forming the double-layer straight paper tube 24 and completing the composite.

[0060] Optional, such as Figure 1 、 Figure 2 、 Figure 14 and Figure 15As shown, in some embodiments, the cutting mechanism includes a cutting support guide wheel 27, a cutter disc 32, a circular knife 31, a cutter disc base 34 and a motor 33. The motor 33 is installed on the cutter disc base 34, the cutter disc 32 is connected to the motor 33, the cutter disc 32 is provided with a circular knife 31, and cutting support guide wheels 27 are provided on both sides of the fixed steel shaft 35. The cutting support guide wheels 27 are used to support the double-layer straight paper tube 24 and the fixed steel shaft 35.

[0061] The beneficial effect of the above optional embodiment is that the setting of the circular knife 31 can better cut the double-layer straight paper tube 24 into multiple sections according to the required length.

[0062] In the above optional embodiment, it should be noted that the cutter disc 32 is a rotating knife, and the motor 33 drives it to rotate counterclockwise. Two circular knife devices are symmetrically arranged 180 degrees around the cutter disc 32. The installation position of the two circular knife devices can be adjusted according to their own axis so that the circular knife 31 is perpendicular to the axis of the double-layer straight paper tube 24 when in the cutting position. While the two circular knife devices revolve with the cutter disc 32, the circular knife 31 of the circular knife device rotates along the cutting direction, and cuts the double-layer straight paper tube 24 through revolution and rotation. The cutter disc 32 and the operating axis of the double-layer straight paper tube 24 are placed at a certain angle. When the circular knife 31 of the circular knife device on the cutter disc 32 cuts the double-layer straight paper tube 24 vertically, it will generate a movement at this angle. This movement is equal to the axial movement of the double-layer straight paper tube 24, realizing synchronous vertical cutting. The rotation speed of the rotary cutting device is related to the linear speed of the two paper supply wheels, and the two paper supply wheels pull out the set When the length of the double-layer straight paper tube 24 is a certain length, the cutter disc 32 rotates 180 degrees to cut a double-layer straight paper tube 24. The faster the corresponding linear speeds of the two paper supply wheels are set, the longer the length of the paper tape pulled out is, and the longer the length of the double-layer straight paper tube 24 cut by the circular knife 31 of the rotary cutting device is, and vice versa. When the length of the double-layer straight paper tube 24 after cutting needs to be changed, the linear speeds of the two paper supply wheels are adjusted, and the angle of the cutter disc 32 is adjusted with the center of the cutter disc base 34 as the center, and the circular knife 31 is adjusted to be perpendicular to the axis of the double-layer straight paper tube 24 at the cutting position. When the diameter of the double-layer straight paper tube 24 needs to be changed, the width of the two paper tapes is adjusted, the diameter of the fixed steel shaft 35 is adjusted, the diameter of each guide rail hole is adjusted, the diameter of the semi-cylinder of the inner layer straight paper tube bracket 19 is adjusted, the diameter of the semi-circular groove of the semi-circular groove soldering iron 23 is adjusted, the diameter of the notch of each group of traction wheels is adjusted, and the diameter of the semi-circular notch of the cutting support guide wheel 27 is adjusted.

[0063] Optional, such as Figure 1 and Figure 2 As shown, in some embodiments, an acceleration wheel 28 is further included, and an acceleration wheel 28 is provided between the cutting mechanism and the collector 30.

[0064] The beneficial effect of the above optional embodiment is that a certain gap is generated between each section of the double-layer straight paper tube 24 by the acceleration of the acceleration wheel 28 , so that the double-layer straight paper tube 24 can be better collected by the collector 30 .

[0065] In the above-described alternative embodiment, it should be noted that a diverting device is also included. The cut double-layer straight paper tubes 24 become double-layer straight hollow paper tubes of fixed length. These tubes are accelerated by an acceleration wheel 28, creating a predetermined gap between each section of the double-layer straight hollow paper tubes. These tubes enter the diverting device, where their axial motion is converted to radial motion, and are collected by a collector 30.

[0066] Optional, such as Figure 1 、 Figure 2 and Figure 10 As shown, in some embodiments, an outer paper tape glue applicator 6 is also included. The outer paper tape glue applicator 6 is arranged between the outer paper tape feeding mechanism and the outer paper tape forming mechanism. The outer paper tape glue applicator 6 is used to glue the outer paper tape 5. The glued side of the outer paper tape 5 is the outer paper tape glued surface 36.

[0067] The beneficial effect of the above optional embodiment is that the setting of the outer paper tape glue applicator 6 allows the inner linear paper tube 18 and the outer linear paper tube 22 to be better bonded to form a double-layer linear paper tube 24.

[0068] In the above-described alternative embodiment, it should be noted that the outer paper tape 5 is coated with glue by the outer paper tape glue applicator 6 before the outer paper tape deflection wheel 7 is turned. After the outer paper tape 5 is folded into the outer linear paper tube 22, the glue-coated surface 36 is on the inner surface. As the outer paper tape 5 is gradually folded, the glue-coated surface 36 on the inner surface of the outer paper tape 5 adheres to the outer surface of the inner linear paper tube 18.
