Description

Technical Field

[0001] The utility model relates to the technical field of paper tube production equipment, in particular to a cloth belt conveying mechanism and a paper tube forming machine. Background Art

[0002] Paper tubes are tubular objects made from paper strips. They have a wide range of uses in production and life. For example, they can be used in tobacco products, as wrappers for tobacco products, or as other functional structures.

[0003] Currently, paper tubes are typically manufactured through automated processing using a paper tube forming machine, which typically includes a raw material storage area, a gluing mechanism, and a forming mechanism. During production, a paper roll made from a paper strip is placed in the raw material storage area. The strip then passes through the gluing mechanism and the forming mechanism. The gluing mechanism first sprays glue onto the overlapped edges of the strip. The circular cavity in the forming mechanism then rolls the flat strip into a paper tube. Because the gluing mechanism pre-coats the strip, the edges of the strip are glued together as the forming mechanism rolls the strip into a tube, forming a stable paper tube.

[0004] In order to drive the paper tube (paper tape) in the entire equipment to move, a cloth belt conveying mechanism is usually set in the forming mechanism. The cloth belt in the cloth belt conveying mechanism provides power to pull the paper tube (paper tape) and transport the paper tube (paper tape) step by step. The cloth belt is also used to roll the paper tape into a paper tube.

[0005] The paper tubes produced by existing technology are single paper tubes. However, with the increase in consumer demand, there is currently a demand for the production of multiple paper tubes. Multiple paper tubes refer to a large paper tube with a large diameter and multiple small paper tubes with small diameters arranged inside.

[0006] However, in the existing cloth belt conveying mechanism, only one cloth belt is usually provided to form one paper tube and drive one paper tube (paper belt) to move. It is not possible to synchronously form and convey multiple small diameter paper tubes through one device.

[0007] Therefore, how to provide a cloth belt conveying mechanism to meet the synchronous forming and conveying of multiple paper tubes is a technical problem that needs to be solved urgently in this field. Utility Model Content

[0046] The utility model provides a cloth belt conveying mechanism, which includes a driving unit, a driving wheel, a driven wheel, a cloth belt, and a guide plate; the driving unit is connected to the driving wheel to drive the driving wheel to rotate; the driven wheel includes a first driven wheel and a second driven wheel, and the first driven wheel and the second driven wheel are arranged in parallel and spaced apart; the cloth belts are provided with three, and the three cloth belts are respectively wrapped around the driving wheel, the first driven wheel, and the second driven wheel in sequence, and the three cloth belts are arranged in parallel and spaced apart along the axial direction of the driving wheel, and the three cloth belts are sequentially divided into a first cloth belt, a second cloth belt, and a third cloth belt; the guide plate is located at the rear side of the first driven wheel, and an accommodating channel is opened on the guide plate, and along the width direction of the guide plate, the accommodating channel includes a first channel, a second channel, and a third channel arranged in sequence; the first cloth belt passes through the first channel, the second cloth belt passes through the second channel, and the third cloth belt passes through the third channel. The cloth belt conveyor mechanism is equipped with three cloth belts. When the driving unit drives the driving wheel to rotate, the three cloth belts are driven synchronously, thereby simultaneously conveying three paper tubes. The guide plate is provided with the first channel, the second channel, and the third channel, so as to accurately guide the conveying position of the paper tubes and form them.

[0047] Please refer to Figures 1 to 3 In one embodiment, a cloth belt conveying mechanism 100 is provided, which is mainly used to meet the conveying requirements of multiple paper tubes.

[0048] The fabric conveying mechanism 100 includes a drive unit (not shown), a driving wheel 10, a driven wheel 20, a fabric belt 30, and a guide plate 40. The drive unit is connected to the driving wheel 10 to drive the driving wheel 10 to rotate. The drive unit can be a motor. The driven wheels 20 include a first driven wheel 21 and a second driven wheel 22. The first driven wheel 21 and the second driven wheel 22 are arranged parallel to each other and spaced apart.

[0049] Three fabric belts 30 are provided, and the three fabric belts 30 are sequentially wound around the driving pulley 10, the first driven pulley 21, and the second driven pulley 22. That is, after the fabric belt 30 is wound from the driving pulley 10, it first winds around the first driven pulley 21, then around the second driven pulley 22, and then back around the driving pulley 10 via the second driven pulley 22. The three fabric belts 30 are arranged parallel to each other and spaced apart along the axial direction of the driving pulley 10. The three fabric belts 30 are sequentially divided into a first fabric belt 31, a second fabric belt 32, and a third fabric belt 33. Since there are three fabric belts 30, when the drive unit drives the driving pulley 10 to rotate, it can simultaneously drive the three fabric belts 30 to operate.

[0050] The guide plate 40 is located behind the first driven pulley 21, with the terms "rear" and "front" being relative to the direction of travel of the cloth belt 30. The guide plate 40 defines a receiving channel. Along the width of the guide plate 40 (which is parallel to the axial direction of the driving pulley 10), the receiving channel comprises a first channel, a second channel, and a third channel, spaced sequentially. The first cloth belt 31 passes through the first channel, the second cloth belt 32 passes through the second channel, and the third cloth belt 33 passes through the third channel. Specifically, at least a portion of the receiving channel has an arc-shaped cross-section, enabling the channel to bend the cloth belt 33 into an arc-shaped structure. As the cloth belt 33 moves the small paper belt, the arc-shaped structure bends the cloth belt 33, thereby bending the paper belt into a paper tube. In other words, the cloth belt 33 not only drives the small paper belt but also forms the paper tube. The cavity for forming the paper tube is formed by the bending and winding of the cloth belt 33. After the small paper tube is driven into the accommodating channel, the cloth tape 33 is bent due to the guidance of the accommodating channel, so that the cloth tape 33 bends the small paper tape and shapes the small paper tape into a paper tube.

[0051] It should be noted that in other embodiments, the number of cloth belts 30 may be greater, for example, a fourth cloth belt, a fifth cloth belt, etc. may be provided, and accordingly, the number of accommodating channels in the guide plate 40 may also be changed accordingly. This embodiment is described using only three cloth belts 30 as an example.

[0052] The cloth belt conveying mechanism 100 is provided with multiple cloth belts 30, thereby synchronously driving multiple paper tubes to move, meeting the conveying requirements of multiple paper tubes. Furthermore, multiple receiving channels are provided to guide and shape the paper tubes during conveyance, ensuring that the paper tubes do not deflect during conveyance.

[0053] Preferably, in one embodiment, the fabric belt conveying mechanism 100 further includes an adjusting wheel assembly 50 and a tensioning wheel assembly 60. The adjusting wheel assembly 50 and the tensioning wheel assembly 60 are located behind the driving wheel 10 and in front of the first driven wheel 21. The fabric belt 30 is wound around the adjusting wheel assembly 50 and the tensioning wheel assembly 60 before being wound back onto the first driven wheel 21. The arrangement of the adjusting wheel assembly 50 and the tensioning wheel assembly 60 allows for control and tensioning of each fabric belt 30, ensuring stable operation.

[0054] Preferably, in one embodiment, the adjustment wheel assembly 50 includes a first adjustment wheel 51, a second adjustment wheel 52, a third adjustment wheel 53, and a fourth adjustment wheel 54, which are arranged in parallel and spaced apart. The tensioning wheel assembly 60 includes a first tensioning wheel 61, a second tensioning wheel 62, and a third tensioning wheel 63, which are arranged in parallel and spaced apart. The first tensioning wheel 61 is located below the first adjustment wheel 51 and the second adjustment wheel 52, and is located between the first adjustment wheel 51 and the second adjustment wheel 52. The second tensioning wheel 62 is located below the second adjustment wheel 52 and the third adjustment wheel 53, and is located between the second adjustment wheel 52 and the third adjustment wheel 53. The third tensioning wheel 63 is located below the third adjustment wheel 53 and the fourth adjustment wheel 54, and is located between the third adjustment wheel 53 and the fourth adjustment wheel 54. The first fabric tape 31 passes through the tops of the first, second, and third adjustment wheels 51, 52, and 53, then wraps around the bottom of the third tensioning wheel 63 and exits through the top of the fourth adjustment wheel 54. The second fabric tape 32 passes through the tops of the first and second adjustment wheels 51, 52, then wraps around the bottom of the second tensioning wheel 62 and exits through the tops of the third and fourth adjustment wheels 53, 54. The third fabric tape 33 passes through the top of the first adjustment wheel 51, then wraps around the bottom of the first tensioning wheel 61 and exits through the tops of the second, third, and fourth adjustment wheels 52, 53, and 54. This structure ensures that the first, second, and third fabric tapes 31, 32, and 33 are properly tensioned. It also allows the first, second, and third fabric tapes 31, 32, and 33 to be of the same length and type, allowing them to be replaced during maintenance.

[0055] Preferably, in one embodiment, the system further includes a first tensioning control unit 64, a second tensioning control unit 65, and a third tensioning control unit 66. The first tensioning control unit 64 is connected to the first tensioning wheel 61 to drive the first tensioning wheel 61 upward and downward. The second tensioning control unit 65 is connected to the second tensioning wheel 62 to drive the second tensioning wheel 62 upward and downward. The third tensioning control unit 66 is connected to the third tensioning wheel 63 to drive the third tensioning wheel 63 upward and downward. The provision of the tensioning control unit makes control of the tensioning wheels more convenient and simple. Furthermore, when the fabric belt 30 needs to be inspected or replaced, the tensioning control unit simply raises the tensioning wheel to loosen the fabric belt 30, facilitating inspection and replacement. After replacement, the tensioning control unit simply lowers the tensioning wheel to tension the fabric belt 30. Specifically, the first tensioning control unit 64, the second tensioning control unit 65, and the third tensioning control unit 66 can all be pneumatic cylinders.

[0056] Preferably, in one embodiment, the fabric conveying mechanism 100 further includes three fabric deviation adjustment rollers 70, with each fabric tape 30 passing through one of these rollers. The rollers 70 can be used to adjust the lateral position of the corresponding fabric tape 30 to prevent the fabric tape 30 from skewing. Specifically, the rollers 70 are manually adjustable and can be mounted on the side trusses 80.

[0057] Preferably, in one embodiment, the tape conveying mechanism 100 further includes a pressure block 90, which is positioned above the guide plate 40 and is used to position the paper tube. The pressure block 90 can be used to position the top adhesive joint of the paper tube, thereby preventing the paper tube from loosening from the joint and affecting its formation. Specifically, in one embodiment, the pressure block 90 is a hot pressing block (a heating element, such as a resistance wire, can be provided within the pressure block 90), and the receiving channel has an open-top structure. This allows the pressure block 90 to heat and melt the adhesive at the top adhesive joint of the paper tube, ensuring smooth formation of the paper tube.

[0058] Preferably, in one embodiment, the pressing block 90 is movably mounted above the guide plate 40, that is, the pressing block 90 can move relative to the guide plate 40, thereby changing the positional relationship between the pressing block 90 and the guide plate 40, thereby facilitating maintenance operations. Specifically, in one embodiment, the pressing block 90 is reversibly mounted on the frame of the paper tube forming machine, so that the pressing block 90 can be flipped relative to the guide plate 40. When maintenance operations are required, the pressing block 90 can be simply flipped off the guide plate 40.

[0059] Preferably, in one embodiment, the lower surface of the pressing block 90 is provided with three arc grooves, namely a first arc groove, a second arc groove, and a third arc groove. The first arc groove is located above the first channel, the second arc groove is located above the second channel, and the third arc groove is located above the third channel. This structure can better adapt to round paper tubes.

[0060] Please refer to Figure 4 In one embodiment, a paper tube forming machine 200 is provided. The machine comprises a raw material placement station 210, a gluing mechanism 220, and a forming mechanism 230, which are sequentially arranged. The forming mechanism 230 incorporates the tape conveying mechanism 100. The raw material placement station 210 is used to place a paper roll formed from a wound paper tape. The paper tape in the roll first flows into the gluing mechanism 220 for gluing, and then flows into the forming mechanism 230 for forming into a paper tube. The gluing mechanism 220 may be equipped with multiple paper tape circulation channels and multiple glue guns, allowing for simultaneous gluing of multiple paper tapes. The forming mechanism 230 may also be equipped with multiple corresponding cavities, allowing for simultaneous forming of multiple paper tubes. Specifically, in one embodiment, the gluing mechanism 220 applies hot melt adhesive to the edges of the paper tape, and the forming mechanism 230 is equipped with a hot press forming block. The tape conveying mechanism 100 pulls the paper tube, thereby driving the paper tube (paper tape) to continuously move backward.

[0061] Preferably, in one embodiment, a paper tube forming unit is further provided, comprising the paper tube forming machine 200 and a large paper tube forming machine 300. The forming mechanism of the large paper tube forming machine 300 is located behind the cloth belt conveying mechanism 100. The large paper tube forming machine 300 is used to form large-diameter paper tubes. After the small paper tubes formed by the paper tube forming machine 200 are fed into the forming mechanism of the large paper tube forming machine 300, the small paper tubes are positioned inside the large paper tubes. This results in the final formed paper tube having a multiple paper tube structure (i.e., a structure in which a large paper tube contains multiple small paper tubes), thereby meeting production requirements.

[0062] The large paper tube forming machine 300 may also include corresponding raw material placement positions, gluing mechanisms, and forming mechanisms, so as to realize automatic rolling and forming of paper strips into paper tubes, which will not be described in detail here.

[0063] The above is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the scope of protection of the present invention.
