[0038] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Please see Figures 1-4 In this embodiment of the present invention, a pressing device for paper towel production includes a transmission belt 1. Guide rails 2 are respectively provided on the left and right sides of the transmission belt 1 to provide guidance when the transmission belt 1 slides in the longitudinal direction. The guide rails 2 are slidably mounted on the transmission belt 1. An adjusting component for driving the transmission belt 1 to move longitudinally is provided at the upper end of the transmission belt 1. The transmission belt 1 includes a drive shaft 11, a connecting seat 12, a first driven shaft 13, a second driven shaft 14, and a pressing belt 15. Side plates 121 are respectively provided on both sides of the connecting seat 12. The inner side of the side plate 121 is equipped with a drive shaft 11, and the outer side of the side plate 121 is provided with a slider 122 for slidingly mounting the guide rail 2. A first through hole 1211 is opened at the front end of the side plate 121, and a second through hole 1212 is opened at the rear end of the side plate 121. A first driven shaft 13 is installed at the first through hole 1211, and a second driven shaft 14 is installed at the second through hole 1212. The pressure belt 15 is respectively fitted with the drive shaft 11, the first driven shaft 13, and the second driven shaft 14. An adjusting component is detachably installed at the upper end of the connecting seat 12. Both the first driven shaft 13 and the second driven shaft 14 are provided with bearings at both ends to contact the surface of the pressure belt 15, so that the drive shaft 11 can achieve the transmission effect of the transmission belt 1 when rotating.

[0040] Specifically, the adjustment mechanism controls the longitudinal movement of the transmission belt in various ways, including but not limited to using a lead screw and slider 122 connection, or using an electric cylinder. The connection between the side plate 121 and the connecting seat 12 includes, but is not limited to, a detachable assembly, or an integral molding method, which can be achieved through machining or casting.

[0041] like Figure 1-3 As shown, two sets of guide rails 2 are respectively set on the left and right sides of the transmission belt, so that the transmission belt can be more stable when descending or ascending.

[0042] The working principle of this embodiment is as follows: the movement of the transmission belt in the longitudinal direction can be controlled by the adjusting component. A slider 122 is provided on the outer side of the side plate 121 for sliding connection with the guide rail 2. The guide rail 2 can provide guidance for the lifting or lowering of the transmission belt, and also make the transmission belt move more smoothly. The height-adjustable pressing device can adapt to the production of paper towels of different specifications.

[0043] Further as Figures 1-6 In this embodiment of the invention, the adjusting component is a pitch screw 3. The connecting seat 12 has a threaded hole, and the connecting seat 12 also has a bearing 4 mounted on its upper surface. The bearing 4 corresponds to the threaded hole. One end of the pitch screw 3 is inserted into the bearing 4 and threadedly connected to the threaded hole. A knob 31 for rotating the pitch screw 3 is also provided at the other end. The operator can rotate the pitch screw 3 by rotating the knob 31, thereby adjusting the height of the connecting seat 12. Further... Figure 5-6 As shown, a fixed plate 21 is installed at the upper end of the guide rail 2 to restrict the longitudinal movement of the adjusting screw 3, so that the adjusting screw 3 can only rotate. A fixed bearing is provided on the fixed plate 21. After the adjusting screw 3 inserts the fixed bearing, a bearing 4 is inserted and threadedly connected to the threaded hole.

[0044] In another embodiment of this utility model, the adjusting member can also be an electric cylinder (not shown in the figure). The electric cylinder (not shown in the figure) is longitudinally mounted on the upper end surface of the connecting seat 12, and the output end of the electric cylinder (not shown in the figure) is mounted on the upper end surface of the connecting seat 12, so that the electric cylinder (not shown in the figure) can control the rise or fall of the transmission belt by extension and retraction.

[0045] Further as Figure 4 In this embodiment of the invention, the horizontal height of the drive shaft 11 is higher than that of the first driven shaft 13, and the horizontal height of the drive shaft 11 is higher than that of the second driven shaft 14. This increases the contact area between the drive shaft 11 and the pressure belt 15, allowing the drive shaft 11 to better drive the pressure belt 15 when rotating.

[0046] Further as Figures 1-4 In this embodiment of the invention, the transmission belt is further provided with a first clamping shaft 16 and a second clamping shaft 17. The first clamping shaft 16 is installed near the front end of the drive shaft 11 and contacts the outer surface of the clamping belt 15. The second clamping shaft 17 is installed near the rear end of the drive shaft 11 and contacts the outer surface of the clamping belt 15. The first clamping shaft 16 is used to clamp the clamping belt 15 at the front end of the drive shaft 11, thereby increasing the contact area between the front end of the drive shaft 11 and the clamping belt 15. The second clamping shaft 17 is used to clamp the clamping belt 15 at the rear end of the drive shaft 11, thereby increasing the contact area between the rear end of the drive shaft 11 and the clamping belt 15, thus improving the transmission effect of the transmission belt.

[0047] Further as Figures 1-6 In this embodiment of the invention, the pressing device further includes a pressing conveyor belt 5, which is installed at the lower end of the transmission belt. The pressing conveyor belt 5 includes a pressing rotating shaft 51, a pressing driven shaft, and a pressing belt 53. One end of the pressing belt 53 is fitted with the pressing rotating shaft 51, and the other end of the pressing belt 53 is fitted with the pressing driven shaft. When the pressing rotating shaft 51 rotates, it can drive the pressing belt 53, and the pressing belt 53 can drive the pressing driven shaft to rotate, thereby achieving the conveying effect.

[0048] Further as Figures 1-6 In this embodiment of the invention, a synchronous rotation device is provided at one end of the pressing rotating shaft 51. The synchronous rotation device includes a first synchronous transmission belt 541, a second synchronous transmission belt 542, and a synchronous rotation motor 543. One end of the first synchronous transmission belt 541 is connected to the pressing rotating shaft 51, and the output end of the synchronous rotation motor 543 is connected to the other end of the first synchronous transmission belt 541 to drive the first synchronous transmission belt 541. One end of the second synchronous transmission belt 542 is connected to the pressing rotating shaft 51, and the other end of the second synchronous transmission belt 542 is connected to one end of the drive shaft 11. The synchronous rotation device enables synchronous transmission between the pressing conveyor belt 5 and the transmission belt.

[0049] Specifically, the first synchronous transmission belt 541 includes a first synchronous driving gear 5411, a first synchronous driven gear 5412, and a first synchronous belt 5413. The first synchronous driven gear 5412 is mounted and clamped to the rotating shaft 51. The first synchronous driving gear 5411 is connected to the output end of the synchronous rotating motor 543 to drive the first synchronous driving gear 5411 to rotate. One end of the first synchronous gear belt is meshed with the first synchronous driving pulley, and the other end of the first synchronous gear belt is meshed with the first synchronous driven gear 5412.

[0050] The second synchronous transmission belt 542 includes a second synchronous driving gear 5421, a second synchronous driven gear 5422, and a second synchronous belt 5423. The second synchronous driving gear 5421 is mounted and presses against the rotating shaft 51. The second synchronous driven gear 5422 is mounted on one end of the driving shaft 11. One end of the second synchronous gear belt is meshed with the second synchronous driving pulley, and the other end of the second synchronous gear belt is meshed with the second synchronous driven gear 5422.

[0051] The working principle of this embodiment is as follows: The operator powers on the synchronous rotating motor 543 to drive the first synchronous driving gear 5411 to rotate and drive the first synchronous belt 5413. Under the drive of the first synchronous belt 5413, the first driven gear also rotates synchronously, thereby causing the pressing rotating shaft 51 to rotate synchronously, so that the pressing conveyor belt 5 achieves the conveying effect, and also drives the second synchronous driving gear 5421 to rotate. The second synchronous driving gear 5421 drives the second synchronous belt 5423 to rotate and also drives the second synchronous driven gear 5422 to rotate, thereby driving the rotating shaft to rotate, so that the entire transmission belt achieves the conveying effect. Moreover, the transmission belt and the pressing conveyor belt 5 are conveyed synchronously, which facilitates the conveying while pressing the paper towel.

[0052] Further as Figure 7 and Figure 9 In this embodiment of the utility model, a conveying device including the above-mentioned pressing device is provided. The conveying device further includes a first feeding conveyor belt 6, an infeed conveyor belt 7, and a pushing module 8. The pressing device is located on the left side of the first feeding conveyor belt 6. The infeed conveyor belt 7 is installed at the rear end of the first feeding conveyor belt 6, and the conveying direction of the infeed conveyor belt 7 is consistent with the conveying direction of the first feeding conveyor belt 6. The pushing module 8 is installed at the rear end of the infeed conveyor belt 7. The pushing module 8 includes a pushing plate 81, a pushing conveyor belt 82, and a first rotating motor 83. One end of the pushing plate 81 extends to the left and right sides to form a pushing end. The other end of the pushing plate 81 is detachably installed on the surface of the pushing conveyor belt 82. The pushing conveyor belt 82 is installed at the rear end of the infeed conveyor belt 7 and conveys in a back-to-back direction. The output end of the first rotating motor 83 is connected to a rotating end of the pushing conveyor belt 82 to drive the pushing conveyor belt 82.

[0053] The working principle of the feeding conveyor belt 82 is consistent with that of existing conveyor belts, both including a set of driving wheels, a belt for transporting materials, and driven wheels that rotate under the drive of the belt. This utility model will not elaborate further. The tissues to be packaged are placed at one end of the feeding conveyor belt 7, and a stacking plate is provided at the other end of the feeding conveyor belt 7 to hold the tissues in place. The tissues are continuously stacked at the other end of the feeding conveyor belt 7 under its transmission. When a certain quantity is stacked to meet the needs of secondary packaging, the pushing plate 81 pushes the stacked tissues awaiting secondary packaging to the first feeding conveyor belt 6 for transport.

[0054] In this embodiment, the operator powers on the first rotating motor 83 to drive the pusher conveyor belt 82. The pusher conveyor belt 82 can move from back to front or from front to back. When the pusher conveyor belt 82 moves from back to front, it can drive the pusher plate 81 to move towards the first feeding conveyor belt 6. When the tissues to be packaged are stacked on the infeed conveyor belt 7, the pusher plate 81 can move the stacked tissues to the first feeding conveyor belt 6. Conversely, when the pusher conveyor belt 82 moves from front to back, the pusher plate 81 is reset.

[0055] In another embodiment of this utility model, the first feeding conveyor belt 6 can be used to convey the paper towels to be repackaged to the pressing conveyor belt 5 for pressing.

[0056] Further as Figure 7 and Figure 9 In this embodiment of the present invention, the upper end of the first feeding conveyor belt 6 is further provided with a first material blocking device 9. The first material blocking device 9 includes a material blocking conveyor belt 91, a first material blocking plate 92, and a second rotating motor 93. The material blocking conveyor belt 91 is detachably installed on the upper end of the first feeding conveyor belt 6. The lower end of the first material blocking plate 92 extends to the left and both sides to form a material blocking end. The upper end of the first material blocking plate 92 is detachably installed with the belt surface of the material blocking conveyor belt 91. The output end of the second rotating motor 93 is connected to a rotating end of the material blocking conveyor belt 91.

[0057] like Figure 7 As shown, the material blocking conveyor belt 91 includes a set of drive pulleys driven by a belt and driven pulleys driven by the belt. The rotating end of the second rotating motor 93 is installed at the drive pulley to drive the material blocking conveyor belt 91 to convey material.

[0058] The working principle of this embodiment is as follows: The tissues to be repackaged are stacked at the feed conveyor belt 7 and moved to the first feeding conveyor belt 6 by the pusher plate 81. The tissues then come into contact with the first baffle plate 92 and are conveyed by the first feeding conveyor belt. The second rotating motor 93 drives the baffle conveyor belt 91 to slide the first baffle plate 92 on the end face of the first feeding conveyor belt 6, allowing adjustment of the number of tissue layers pushed to the first feeding conveyor belt 6 to accommodate different tissue packaging requirements.

[0059] Further as Figure 7 and Figure 9 In this embodiment of the utility model, the left and right sides of the first baffle plate 92 are respectively provided with baffle guide rails 94 to provide guidance when the first baffle plate 92 slides in the front and back direction, and the first baffle plate 92 is slidably mounted with baffle guide rails 94.

[0060] like Figure 7As shown, by setting the baffle guide rail 94, the first baffle plate 92 can be more stable when sliding, and the shaking of the first baffle plate 92 can be reduced when it is pressed against the paper towel.

[0061] Further as Figure 8-9 In this embodiment of the utility model, the conveying device further includes a second feeding conveyor belt 10. One end of the second feeding conveyor belt 10 is close to the pressing device, and the other end of the second feeding conveyor belt 10 is close to one end of the first feeding conveyor belt 6. A second baffle plate 101 is provided on the upper surface of the second feeding conveyor belt 10.

[0062] like Figure 8 As shown, the conveying direction of the second feeding conveyor belt 10 is the same as that of the first feeding conveyor belt 6. The second feeding conveyor belt 10 is used to convey the paper towels to be packaged for the second time to the pressing conveyor belt 5 for pressing the paper towels.

[0063] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
