[0002] The structure of the hookah is basically composed of four parts: the body, the bowl, the hookah pipe and the mouthpiece; one end of the hookah pipe is connected to the body, and the other end of the hookah pipe is connected to the mouthpiece. The basic hookah has only one mouthpiece, and there are also hookahs that can be used by multiple people at the same time. One body can be connected to multiple hookah pipes. In some social occasions, people often share a hookah. Since it is used by multiple people, disposable hookah pipes are usually used for hygiene reasons to prevent infectious diseases.

[0003] Due to hygiene and health issues, users in the Middle East all use disposable hookah pipes. The hookah pipes sold on the market are basically a kind of bendable tube with a bellows structure. A mouthpiece is connected to one end of the hookah pipe, and there is a connecting pipe for connecting to the cigarette pot at the other end of the hookah pipe. The connecting pipe adopts a pluggable structure design. It can be used by simply plugging the connecting pipe into the pot body. When replacing the hookah pipe, just unplug the connecting pipe and replace it with a new one.

[0063] The positional relationships described in the following embodiments include: up, down, left and right. Unless otherwise specified, they are all based on the directions in which the components are drawn in the drawings.

[0064] See also Figures 1 to 3 This is a structural appearance diagram and a detailed structural schematic diagram of an embodiment of a device for making a bendable paper hookah pipe of the present application.

[0065] The manufacturing method and device of the bendable paper hookah pipe of the present application are basically used to make a bellows tube structure on the tube wall of a prepared paper spiral tube P, thereby forming a bendable paper hookah pipe. The paper spiral tube P uses paper as a raw material, and then spirally winds the paper or paper strips and glues them together with glue to form a paper spiral tube P with a spiral tube structure. The paper spiral tube P still has good plasticity before the glue is completely dried and hardened or in a semi-dry state (that is, the glue has not completely dried and hardened), which is conducive to forming a bellows tube structure through the method of the present application and then making a bendable paper hookah pipe. The material of the paper is selected from stone paper, traditional fiber paper, and a multi-layer composite paper made of stone paper and traditional fiber paper.

[0066] The manufacturing device of the bendable paper hookah pipe of the present application basically forms a bellows structure by rolling the wall of the paper spiral pipe P through the coordinated operation of a roller R and a central support shaft 20. Figure 1 In the exemplary structure shown, the paper spiral tube P is placed into a working position in the roller R when the adhesive is semi-dry (see Figure 2), in one embodiment, a plurality of paper spiral tubes P are placed one by one in a hopper 10, the cross section of the hopper 10 is roughly funnel-shaped, the hopper 10 is located above the roller, and an outlet 11 is provided at the bottom of the hopper 10, and each time a paper spiral tube P falls downward from the outlet 11 into the roller R.

[0067] The roller R includes a driving unit, a movable carrier 34 and at least one rolling wheel 30. The outer surface of the rolling wheel 30 has a plurality of protruding annular embossings 301. These annular embossings 301 are arranged at intervals along the axial direction of the rolling wheel 30, so that these embossings 301 form a shape like a bellows tube structure on the outer surface of the rolling wheel 30. The driving unit is used to drive the rolling wheel 30 to rotate. An embodiment of the driving unit includes a motor 31 (commonly known as a motor), a pulley 32 and a belt 33. The pulley 32 is arranged on the rotating shaft of the rolling wheel 30. The belt 33 connects the output shaft of the motor 31 and the pulley 32. The axis of the rolling wheel 30 is parallel to the axis of the paper spiral tube P. The rolling wheel 30 is arranged on the movable carrier 34. The movable carrier 34 is used to move the rolling wheel 30 to an action position S1 and a standby position S2 (the direction of movement is shown in FIG. 2 ). Fig. 9 The paper spiral tube P is moved to the standby position S2 in the direction away from the central support shaft 20, and then the central support shaft 20 is pulled out of the paper spiral tube P after rolling. The annular embossing 301 of the rolling wheel 30 in the action position S1 will be pressed on the outer surface of the paper spiral tube P, and conversely, the annular embossing 301 of the rolling wheel 30 in the standby position S2 will not contact the outer surface of the paper spiral tube P.

[0068] The central support shaft 20 has a plurality of annular convex grooves 201 (see FIG. Figure 3 ), there is a spacing between any two adjacent annular convex patterns 201, the axis of the central support shaft 20 is parallel to the axis of the rolling wheel 30, the central support shaft 20 can penetrate the center of the paper spiral tube P, especially the central support shaft 20 penetrates the center of the paper spiral tube P in the working position, so that the tube wall of the paper spiral tube P is between the central support shaft 20 and the rolling wheel 30 (see Fig. 9 ), the rolling wheel 30 and the central support shaft 20 work together to roll the wall of the paper spiral tube P to form a bellows tube structure.

[0069] The roller R can move to a predetermined position along a direction parallel to the axis of the paper spiral tube P, and then cooperate with the central support shaft 20 to roll on the tube wall of the paper spiral tube P to form a section of accordion tube structure. In other embodiments, the roller R can move to multiple predetermined positions along a direction parallel to the axis of the paper spiral tube P, and then roll on the tube wall of the paper spiral tube P to form multiple sections of accordion tube structures, and these accordion tube structures can be adjacent to each other end to end to form a continuous accordion tube structure. In other embodiments, there is a spacing distance between any two adjacent accordion tube structures in the multiple accordion tube structures to form a discontinuous accordion tube structure.

[0070] In one embodiment, the cross-sectional shape of the tube wall of the accordion tube structure is a waveform extending along the axial direction, and the waveform is determined by the shapes of the annular embossings 301 and the annular convex grooves 201. In one embodiment, the waveform is any one of a circular arc wave, a triangular wave, a sawtooth wave and a chord wave.

[0071] An embodiment of the movable carrier 34 includes: a pulley 341, a movable seat 342 and a first driver 343. The driving unit of the roller R and the first driver 343 are arranged on the pulley 341. The rolling wheel 30 is rotatably arranged on the movable seat 342. The central support shaft 20 can be connected to the pulley 341 through a bracket 21. Therefore, the roller R and the central support shaft 20 can be synchronously moved to a predetermined position; the first driver 343 is used to drive the movable seat 342 to move, and then move the rolling wheel 30 to the said action position S1 and the standby position 32. One way of moving the movable seat 342 is to slide on the pulley 341. The first driver 343 shown in the figure is a reciprocating electromagnet, but it is not limited to this. In other embodiments, the first driver 343 can also be, for example, a pneumatic cylinder, a stepping motor or a servo motor combined with a lead screw mechanism.

[0072] Figure 1 A preferred embodiment of the present application is illustrated, with two central support shafts 20 (referred to as the first support shaft 20A and the second support shaft 20B) and two rollers R (referred to as the first roller R1 and the second roller R2), wherein the first support shaft 20A and the first roller R1 are a group and can move synchronously along the axial direction of the paper spiral tube P (for the convenience of explanation, the combination of the first support shaft 20A and the first roller R1 is referred to as the first rolling unit hereinafter), the second support shaft 20B and the second roller R2 are a group and can move synchronously along the axial direction of the paper spiral tube P (for the convenience of explanation, the combination of the second support shaft 20B and the second roller R2 is referred to as the second rolling unit hereinafter), and the first rolling unit is located at a first stop position at one end of the axial line of the paper spiral tube P when no rolling operation is performed (see Figure 6), the second rolling unit is located at the second stop position at the other end of the axis of the paper spiral tube when the rolling operation is not performed. In a preferred embodiment, when the paper spiral tube P falls to the operating position, the axial ends of the paper spiral tube P just fall on the movable carrier 34 of the first roller and the movable carrier 34 of the second roller (see Figure 2 ); In one embodiment, the pulley 341 of the movable carrier 34 of the first roller R1 is provided with a first receiving groove 344, and the pulley 341 of the movable carrier 34 of the second roller R2 is provided with a second receiving groove 345, and the axial ends of the paper spiral tube P dropped to the working position fall exactly on the first receiving groove 344 and the second receiving groove 345 respectively.

[0073] Then, when the rolling operation is to be performed, the first rolling unit and the second rolling unit are synchronously moved along the axial direction of the paper spiral tube P to a predetermined position (see Figure 4 ), at the same time, the central support shaft 20 (including the first support shaft 20A and the second support shaft 20B) will also penetrate into the center of the paper spiral tube P.

[0074] In a preferred embodiment of the present application, the first rolling unit and the second rolling unit are arranged on a track 41. Basically, the pulley 341 of the aforementioned roller R (including the first roller R1 and the second roller R2) can slide on the track 41, and the long axis direction of the track 41 is parallel to the axis of the paper spiral tube P. The track 41 is provided with a second driver 42 for driving the first rolling unit and the second rolling unit to move along the axis direction of the paper spiral tube P to one or more predetermined positions. The figure shows an embodiment of the second driver 42, which adopts a belt mechanism 422 driven by a stepper motor or a servo motor 421 to pull the pulley 341 of the first rolling unit and the pulley 341 of the second rolling unit to move on the track 41, but it is not limited to this. Other embodiments of the second driver 42 may also use a stepper motor or a servo motor combined with a lead screw mechanism to drive the first rolling unit and the second rolling unit to move on the track 41.

[0075] In a preferred embodiment of the present application, it includes a clamping mechanism 50. An embodiment of the clamping mechanism 50 includes: a pair of movable jaws 51 and a jaw driver 52. In one implementation mode, the clamping mechanism 50 is arranged on both sides of the central position of the track 41. The jaw driver 52 is basically used to drive the movable jaw 51 to reciprocate. The jaw driver 52 shown in the figure is a reciprocating electromagnet, but it is not limited to this. In other implementation modes, the jaw driver 52 can also be, for example: a pneumatic cylinder, a stepper motor or a servo motor combined with a lead screw mechanism.

[0076] The function of the clamping mechanism 50 is to assist in clamping the paper spiral tube P during the roller R performing multiple rolling operations on the paper spiral tube P. For example: (1) the first rolling unit and the second rolling unit first move to a first predetermined position (see Figure 4 ) After the first rolling operation of the paper spiral tube P is completed, the first rolling unit and the second rolling unit are still in the first predetermined position. The rolling wheels 30 of the first rolling unit and the second rolling unit first move from the action position S1 to the standby position S2, and then the clamping mechanism 50 immediately clamps the paper spiral tube P, and then the first rolling unit and the second rolling unit will move to the second predetermined position (see Figure 4 ); (2) the first rolling unit and the second rolling unit move to a second predetermined position (see Figure 4 ), the rolling wheels 30 of the first rolling unit and the second rolling unit first move from the standby position S2 to the action position S1, and then the clamping mechanism 50 releases the paper spiral tube P, and then the first rolling unit and the second rolling unit perform a second rolling operation on the paper spiral tube P at the second predetermined position; following the same action rules, the paper spiral tube P can be rolled multiple times, thereby completing the rolling operation of multiple accordion tube structures.

[0077] In this application Figure 1 and Fig. 9 A preferred embodiment structure is shown, the rollers (including the first roller R1 and the second roller R2) have three rolling wheels 30 in total, and the three rolling wheels 30 surround the central support shaft 20, and the three rolling wheels 30 can be driven by the same driving unit.

[0078] The extrusion unit 60 includes: a reciprocating extruder 64, a conveying wheel 61, a wheel driving unit (not shown in the figure due to the obstruction of the viewing angle), and a baffle 62. The shape of the conveying wheel 61 is preferably cylindrical. The conveying wheel 61 is located below the working position of the paper spiral tube P, in other words, below the rolling unit (including the first rolling unit and the second rolling unit). The axis of the conveying wheel 61 is parallel to the axis of the paper spiral tube P. The circumferential surface of the conveying wheel 61 has at least one material groove 611 (see Figure 7A to Figure 7C ), the length of the material trough 611 is sufficient to receive and accommodate the paper spiral tube P that falls after rolling is completed, the baffle 62 is located on one side of the transport wheel 61 and is tangent to the circumference of the transport wheel 61, and the wheel driving unit is used to drive the transport wheel 61 to rotate. In one embodiment, the wheel driving unit drives the transport wheel to rotate in a single direction. In one embodiment of the wheel driving unit, a stepping motor or a servo motor is used to provide the power required for rotation. The wheel driving unit drives the transport wheel 61 to rotate and cyclically rotates the material trough 611 to a first position, a second position, and a third position.

[0079] See also Figure 7A to Figure 7C , in the first position ( Fig. 7A ) is used to receive the paper spiral tube P that falls after the roller R completes the rolling, and then the trough 611 rotates to the second position ( Figure 7B ), the baffle 62 can just seal the rolled paper spiral tube P in the material trough 611 that reaches the second position, and the reciprocating squeezer 64 is used to press the rolled paper spiral tube P that reaches the second position. Finally, when the material trough 611 reaches the third position ( Figure 7C ), the opening of the material trough 611 may be downward or approximately downward, so that the paper spiral tube P in the material trough 611 can fall freely, for example, fall to a conveyor belt 63 below. At this point, the production of the bendable paper hookah pipe has been basically completed. If necessary, the conveyor belt 63 can be used to connect other subsequent production steps, such as drying, packaging, etc.

[0080] As another preferred embodiment of the transport wheel 61, a plurality of material grooves 611 ( Figure 8 ), by rotating the conveying wheel 61 in a single direction, each material trough 611 can be cyclically rotated to the aforementioned first position, second position and third position in sequence, forming a continuous operation.

[0081] The reciprocating extruder 64 can use any one of a hydraulic cylinder, a pneumatic cylinder, and an electric lead screw mechanism as a power source to drive an extrusion rod 641 to reciprocate along the axial direction of the paper spiral tube P, so as to extrude the paper spiral tube P that has been rolled into a bellows tube structure in its axial direction.

[0082] Another effect of squeezing the accordion tube structure before the adhesive is completely dried and hardened is that it can appropriately destroy part of the adhesive of the accordion tube structure, which helps the hookah pipe to be easily bent 180 degrees at the position of the accordion tube structure. Even if it is bent 180 degrees, it will not break or crack. In the subsequent process, the drying and hardening of the adhesive can be accelerated by drying or heating. The dried and hardened adhesive has the effect of stabilizing the shape and structure of the accordion tube structure, preventing the accordion tube structure from automatically returning to a straight tube shape.

[0083] The embodiments and / or implementation methods described above are only used to illustrate the preferred embodiments and / or implementation methods for realizing the technology of the present application, and are not intended to limit the implementation methods of the technology of the present application in any form. Any technical personnel in this field may make slight changes or modifications to other equivalent embodiments without departing from the scope of the technical means disclosed in the content of the present application, but they should still be regarded as technologies or embodiments that are essentially the same as the present application.
