Description

Technical Field

[0001] The utility model belongs to the technical field of paper tube processing, and particularly relates to a paper tube drying device. Background Art

[0002] A paper tube is a tubular object made of paper. After the paper is processed into a paper tube, it needs to be dried to quickly solidify the glue and quickly form the paper tube. In the prior art, during the drying process of the paper tube, it is impossible to ensure that the drying rate of the paper tube is fast and uniform, which affects the working efficiency and causes internal stress in the paper tube, resulting in slight deformation of the paper tube.

[0003] In the prior art, such as the application number: CN202320492014.4, the paper tube is placed between the first fixed tube and the second fixed tube, the motor and the heating component are controlled to work, and the rotating fan blades blow the hot air heated by the heating component during operation into the interiors of the plurality of first fixed tubes and the second fixed tubes, and then blow out from a number of through holes and blow on the inner wall and outer surface of the paper tube. At the same time, the hot air in the device can be blown into the bottoms of the first fixed tube and the second fixed tube again through the air inlet hole, the connecting hole, the cavity and the air outlet hole. At this time, the hot air inside the device can circulate and flow, and the hot air in the device blows on various parts of the support plate, so that the temperatures of various parts inside the device are the same.

[0004] However, during the actual operation of the patent, the heat of the hot air ejected from the air outlet holes on the first fixed tube and the second fixed tube that are farther and farther away from the air inlet hole becomes smaller and smaller, and the flow rate of the blown gas also becomes slower and slower, resulting in uneven drying of the paper tube, and the sizes of the first fixed tube and the second fixed tube are not adjustable, so it is impossible to uniformly dry paper tubes of different sizes. Content of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a paper tube drying device, which has the effects of uniformly drying the glue on the paper tube, adapting to the processing of paper tubes of different diameters and removing water vapor.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions: A paper tube drying device includes two inner heating tubes arranged in central symmetry and parallel to each other, two outer heating tubes arranged in central symmetry and parallel to each other, and two limiting rotating shafts arranged in central symmetry and parallel to each other.

[0007] The symmetry centers of the two inner heating tubes, the symmetry centers of the two outer heating tubes, and the symmetry centers of the two limiting rotating shafts are the same. The distance between the two outer heating tubes is greater than the distance between the two inner heating tubes. The distance between the two limiting rotating shafts is greater than the distance between the two inner heating tubes and less than the distance between the two outer heating tubes. A slideway structure is installed at one end of the inner heating tube, the outer heating tube, and the limiting rotating shaft. The limiting rotating shaft is rotationally and drivingly connected to the slideway structure.

[0008] The rotation of the limiting rotating shaft drives the paper tube to rotate, so that the outer heating tube uniformly bakes the outer side of the paper tube, and the inner heating tube uniformly bakes the inner side of the paper tube, so that the glue on the paper tube is uniformly dried.

[0009] In this embodiment, a first slider is fixedly provided at one end of the inner heating tube close to the slideway structure, and a second slider is fixedly provided at one end of the outer heating tube close to the slideway structure. The first slider and the second slider are slidably connected to the slideway structure. A bidirectional threaded rod is provided on the slideway structure. The bidirectional threaded rod is threadedly connected to the first slider and the second slider. One end of the bidirectional threaded rod is provided with a threaded rod motor. The rotation of the output shaft of the threaded rod motor drives the bidirectional threaded rod to rotate. The bidirectional threaded rod meshes with the first slider and the second slider, thereby driving the inner heating tube and the outer heating tube to move. Since the bidirectional threaded rod is a bidirectional threaded rod, the rotation of the bidirectional threaded rod drives the two first sliders to approach or move away from each other, and drives the two second sliders to approach or move away from each other, so that the two inner heating tubes approach or move away from each other, and the two outer heating tubes approach or move away from each other, so as to adapt to processing paper tubes of different diameters. It should be noted that the wall thicknesses of different paper tubes are the same.

[0010] Optionally, a horizontal moving rod is provided between the two limiting rotating shafts. A plurality of rotatably connected rotating shaft sleeves are sleeved on the limiting rotating shafts. A push-pull rod is connected between the horizontal moving rod and the rotating shaft sleeves. Both ends of the push-pull rod are rotatably connected to the rotating shaft sleeve and the horizontal moving rod respectively. The horizontal movement of the horizontal moving rod drives the push-pull rod to push the two limiting rotating shafts to move, so that the two limiting rotating shafts approach or move away from each other. Specifically, when the horizontal moving rod moves to the left, the two limiting rotating shafts move away from each other, and the two limiting rotating shafts are pushed apart by the push-pull rod, so as to adapt to installing a paper tube with a larger size. When the horizontal moving rod moves to the right, the two limiting rotating shafts are pulled to close to each other by the push-pull rod, so as to adapt to installing a paper tube with a smaller size.

[0011] Optionally, one end of the horizontal moving rod is threadedly connected with a lead screw, and the lead screw is threadedly and adaptively connected with the slideway structure. One end of the lead screw is installed with a lead screw motor. By rotating the output shaft of the lead screw motor, the lead screw is driven to rotate, and the horizontal moving rod is driven to move horizontally.

[0012] Optionally, one end of the limiting rotating shaft is installed with a driving rotating shaft motor, and the limiting rotating shaft is driven to rotate by rotating the output shaft of the rotating shaft motor.

[0013] Optionally, a rotating shaft slider is connected to the side of the limiting rotating shaft close to the slideway structure in a limited rotation manner. The rotating shaft motor is fixedly connected to the rotating shaft slider, and the rotating shaft slider is slidably connected to the slideway structure. By rotating the output shaft of the rotating shaft motor to drive the limiting rotating shaft to rotate, and through the sliding between the rotating shaft slider and the slideway structure, the stable up and down movement of the limiting rotating shaft is realized.

[0014] Optionally, the slideway structure includes a horizontally arranged horizontal slideway and a vertically arranged vertical slideway. The first slider and the second slider are both located in the horizontal slideway and are slidably and adaptively connected with the horizontal slideway. A rotating shaft slider is slidably connected in the vertical slideway.

[0015] Optionally, a motor fixing plate is fixedly arranged on the side of the slideway structure close to the horizontal moving rod. A slideway is fixedly arranged on the motor fixing plate. The horizontal moving rod is located in the slideway and is slidably and adaptively connected with the slideway. By setting the sliding connection between the slideway and the horizontal moving rod, the horizontal moving rod is made more stable when moving horizontally.

[0016] Optionally, an air pipe one and an air pipe two are fixedly installed on one side of the slideway structure. A plurality of air blowing ports one arranged linearly and equidistantly are fixedly arranged through the upper part of the air pipe one. A plurality of air blowing ports two arranged linearly and equidistantly are fixedly arranged through the upper end of the air pipe two. The air pipe one is located between the two limiting rotating shafts and the two inner heating pipes. The air pipe two is located on the side of one of the limiting rotating shafts away from the other limiting rotating shaft. One end of the air pipe one is connected to an air pump, and the inner side of the paper tube is blown through the air blowing ports one, and the generated water vapor is blown out from both ends of the paper tube. One end of the air pipe two is connected to an air pump, and the outside of the paper tube is blown through the air blowing ports two, so as to blow away the water vapor on the outside of the paper tube, and the glue on the paper tube is quickly dried.

[0017] In summary, compared with the prior art, the beneficial effects of this solution are as follows:

[0018] 1. The rotation of the limiting rotating shaft drives the rotation of the paper tube, enabling the outer heating tube to evenly bake the outer side of the paper tube and the inner heating tube to evenly bake the inner side of the paper tube, so as to evenly dry the glue on the paper tube.

[0019] 2. By moving the two inner heating tubes closer to or farther away from each other, and the two outer heating tubes closer to or farther away from each other, it is possible to adapt to processing paper tubes of different diameters.

[0020] 3. By blowing air into the inner side of the paper tube through the air blowing port one and blowing air into the outer side of the paper tube through the air blowing port two, the water vapor baked out from the paper tube is blown away, realizing the rapid drying of the glue on the paper tube.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0028] Embodiment 1: Refer to Figures 1 - 3, a paper tube drying device, comprising two inner heating tubes 21 arranged in central symmetry and parallel to each other, two outer heating tubes 23 arranged in central symmetry and parallel to each other, and two limiting rotating shafts 30 arranged in central symmetry and parallel to each other;

[0029] The inner heating tube 21 is used to heat the inner side of the paper tube 40;

[0030] The outer heating tube 23 is used to heat the outer side of the paper tube 40;

[0031] The limiting rotating shaft 30 is used to support and position the paper tube 40, and at the same time provide a rotational force to drive the paper tube 40 to rotate;

[0032] The symmetry centers of the two inner heating tubes 21, the symmetry centers of the two outer heating tubes 23, and the symmetry centers of the two limiting rotating shafts 30 are the same. The distance between the two outer heating tubes 23 is greater than the distance between the two inner heating tubes 21, which is convenient for the paper tube 40 to be installed outside the two inner heating tubes 21;

[0033] The distance between the two limiting rotating shafts 30 is greater than the distance between the two inner heating tubes 21 and less than the distance between the two outer heating tubes 23, which is convenient for the paper tube 40 to be installed inside the two outer heating tubes 23;

[0034] One end of the inner heating tube 21, the outer heating tube 23, and the limiting rotating shaft 30 is provided with a slideway structure 10. The limiting rotating shaft 30 is rotationally and drivingly connected to the slideway structure 10. When the present utility model is in use, the rotation of the limiting rotating shaft 30 drives the paper tube 40 to rotate, so that the outer heating tube 23 uniformly bakes the outer side of the paper tube 40, and the inner heating tube 21 uniformly bakes the inner side of the paper tube 40.

[0035] In this embodiment, a first slider 22 is fixedly provided at one end of the inner heating tube 21 close to the slideway structure 10, a second slider 24 is fixedly provided at one end of the outer heating tube 23 close to the slideway structure 10. The first slider 22 and the second slider 24 are slidably connected to the slideway structure 10, and a bidirectional threaded rod 25 is provided on the slideway structure 10;

[0036] It should be noted that the thread directions of the two-way threaded rod 25 at both sides are different. The two-way threaded rod 25 is threadedly connected to the first slider 22 and the second slider 24. One end of the two-way threaded rod 25 is provided with a threaded rod motor 26. The rotation of the output shaft of the threaded rod motor 26 drives the two-way threaded rod 25 to rotate. The two-way threaded rod 25 meshes with the first slider 22 and the second slider 24, thereby driving the inner heating tube 21 and the outer heating tube 23 to move. Since the two-way threaded rod 25 is a two-way threaded rod, the rotation of the two-way threaded rod 25 drives the two first sliders 22 to approach or move away from each other, and drives the two second sliders 24 to approach or move away from each other, so that the two inner heating tubes 21 approach or move away from each other, and the two outer heating tubes 23 approach or move away from each other, thereby adapting to process paper tubes 40 with different diameters. It should be noted that the wall thicknesses of the paper tubes 40 with different diameters are the same.

A plurality of rotatably connected rotating shaft sleeves 34 are sleeved on the limiting rotating shafts 30. A push-pull rod 35 is connected between the horizontal moving rod 33 and the rotating shaft sleeve 34. Both ends of the push-pull rod 35 are rotatably connected to the rotating shaft sleeve 34 and the horizontal moving rod 33 respectively. The horizontal movement of the horizontal moving rod 33 drives the push-pull rod 35 to push the two limiting rotating shafts 30 to move, so that the two limiting rotating shafts 30 approach or move away from each other. Specifically, when the horizontal moving rod 33 moves to the left, the two limiting rotating shafts 30 move away from each other;

[0038] The push-pull rod 35 is used to push the two limiting rotating shafts 30 to expand, so as to adapt to the installation of a paper tube 40 with a larger size. When the horizontal moving rod 33 moves to the right, the push-pull rod 35 is used to pull the two limiting rotating shafts 30 to close to each other, so as to adapt to the installation of a paper tube 40 with a smaller size.

[0039] In addition, one end of the horizontal moving rod 33 is threadedly connected with a lead screw 36. The lead screw 36 is threadedly engaged with the slideway structure 10. One end of the lead screw 36 is provided with a lead screw motor 37;

[0040] The rotation of the output shaft of the lead screw motor 37 drives the lead screw 36 to rotate, driving the horizontal moving rod 33 to move horizontally.

[0041] In this embodiment, one end of the limiting rotating shaft 30 is provided with a rotating shaft motor 32 which is drivingly installed. The rotation of the output shaft of the rotating shaft motor 32 drives the limiting rotating shaft 30 to rotate.

[0042] Further, a rotating shaft slider 31 is provided on the side of the limiting rotating shaft 30 close to the slideway structure 10 in a limiting rotation connection manner. The rotating shaft motor 32 is fixedly connected to the rotating shaft slider 31, and the rotating shaft slider 31 is slidably connected to the slideway structure 10. By the rotation of the output shaft of the rotating shaft motor 32 to drive the limiting rotating shaft 30 to rotate, and through the sliding between the rotating shaft slider 31 and the slideway structure 10, the stable up-and-down movement of the limiting rotating shaft 30 is realized.

[0043] In this embodiment, the slideway structure 10 includes a horizontally arranged horizontal slideway 11 and a vertically arranged vertical slideway 12. The first slider 22 and the second slider 24 are both located in the horizontal slideway 11 and are slidably connected to the horizontal slideway 11 in a matching manner. The rotating shaft slider 31 is located in the vertical slideway 12 and is slidably connected to the vertical slideway 12 in a matching manner.

[0044] In addition, a motor fixing plate 13 is fixedly provided on the side of the slideway structure 10 close to the horizontal moving rod 33. A slideway 14 is fixedly provided on the motor fixing plate 13. The horizontal moving rod 33 is located in the slideway 14 and is slidably connected to the slideway 14 in a matching manner. By the sliding connection between the provided slideway 14 and the horizontal moving rod 33, the horizontal movement of the horizontal moving rod 33 is made more stable.

[0045] Embodiment 2; Refer to Figures 4 - 5 , the difference between this embodiment and Embodiment 1 is that an air pipe 50 and an air pipe 52 are fixedly installed on one side of the slideway structure 10. One ends of the air pipe 50 and the air pipe 52 are both connected to an air pump. A plurality of air blowing ports 51 arranged linearly at equal intervals are fixedly provided through the air pipe 50. A plurality of air blowing ports 53 arranged linearly at equal intervals are fixedly provided through the upper end of the air pipe 52;

[0046] The air pipe 50 is located at the position between the two limiting rotating shafts 30 and the two inner heating tubes 21. The air pipe 52 is located at the position where one limiting rotating shaft 30 is away from the other limiting rotating shaft 30;

[0047] The inner side of the paper tube 40 is heated by the inner heating tube 21. After heating, water vapor is generated. One end of the air pipe 50 is connected to the air pump, and the inner side of the paper tube 40 is blown through the air blowing ports 51, and the generated water vapor is blown out from both ends of the paper tube 40;

[0048] The external heating tube 23 heats the outside of the paper tube 40. The generated water vapor after heating has one end of the air pipe two 52 connected to an air pump, and blows air through the air blowing port two 53 to the air pump, so as to blow away the water vapor outside the paper tube 40, and finally achieve the effect of quickly blowing away the water vapor on both the inside and outside of the paper tube 40, realizing the rapid drying of the glue on the paper tube 40.
