Such designs have many inconveniences when facing paper tubes of different sizes, different materials or different production requirements.

[0003] Referring to the patent named a paper tube glue spraying device which is convenient to adjust (publication number: CN220746441U), this utility model is provided with a coating roller rotatably connected to the glue discharge port at the bottom of the glue tank. The coating roller directly dips the glue liquid to roll-coat the paper, greatly improving the uniformity of glue liquid coating. At the same time, it is equipped with a throttle valve structure at the top of the glue tank to facilitate the control of the glue liquid flow rate, thereby facilitating the control of the glue liquid coating amount. By setting a glue scraping plate in the spraying tank, the glue liquid on the side end face of the paper is scraped and recycled to avoid excessive glue liquid on the paper affecting the quality of the paper tube.

[0004] Based on the above document, the existing paper tube glue spraying devices in the prior art can mostly only match paper tubes of fixed sizes for glue coating, and it is difficult to adapt to the change of the paper tube diameter, which easily leads to uneven glue liquid spraying, affecting the forming quality and sealing performance of the paper tube. In practical applications, the glue coating position cannot be flexibly adjusted according to diverse production and processing requirements, resulting in a small overall application range and poor practicability of the device. Therefore, this utility model provides a paper tube glue spraying device which is convenient to adjust. Content of the Utility Model

The end of the cross-shaped telescopic rod is fixed with a first section block, and a second section block is sleeved on the first screw rod. The second section block is rotatably connected to the first section block through a connecting rod.

[0008] Preferably, an adjusting nut is screwed on the outer wall of the first screw rod to position one end of the second section block on the first screw rod. An L-shaped strip is fixedly connected to the end of the first section block.

[0009] Preferably, one end of the chassis is fixed with a base, and a motor is installed on the upper end of the base. The power output end of the motor is connected to the power input end of the rotating rod.

[0013] Beneficial effects

[0014] The utility model provides a paper tube glue spraying device which is convenient to adjust. Compared with the prior art, the following beneficial effects are achieved:

[0015] (1). For the paper tube glue spraying device which is convenient to adjust, by designing an adjustable fixing component, the adjustable fixing component uses the rotating rod as a support shaft. The telescoping of the cross-shaped telescopic rod is realized through the connecting rod between the first section block and the second section block, and then the adaptive fixing of paper tubes with different diameters is achieved. This design allows a certain angle adjustment space when fixing the paper tube to adapt to different positions or slight deformations of the paper tube. The adjusting nut is screwed tightly on the first screw rod to fix the position of the second section block, thereby locking the fixing state of the paper tube. The L-shaped strip is in direct contact with the paper tube to provide stable support, and it can be used to fix paper tubes of different sizes.

[0016] (2) The paper tube glue spraying device that is easy to adjust is driven by a motor. The rotating rod drives the paper tube to rotate. This rotating design enables the glue to be coated on the surface of the paper tube more evenly and quickly. The motor also drives the second screw to rotate through the meshing transmission of the first bevel gear and the second bevel gear. The second screw is threadedly connected to the lifting pressure plate. Therefore, when the second screw rotates, the lifting pressure plate moves up and down in the glue adding box. A sealing strip that fits the inner wall of the box is provided around the lifting pressure plate. The up and down movement of the lifting pressure plate is used to adjust the pressure of the glue in the glue adding box to ensure that the glue can stably and continuously flow to the glue spreading plate through the diversion pipe. The glue spreading plate receives the glue from the glue adding box through the diversion pipe and evenly sprays the glue on the surface of the rotating paper tube through a plurality of groups of spraying heads at its lower end, and the operation is convenient.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a paper tube glue spraying device that is easy to adjust, including a chassis 1. An upper part on one side of the chassis 1 is fixedly provided with a mounting plate 2. A paper tube fixing mechanism is installed on the mounting plate 2. The paper tube fixing mechanism includes:

[0024] An adjustable fixing component 3 is arranged on one side of the mounting plate 2 and includes a rotating rod 31 fixedly mounted on the mounting plate 2. One end of the rotating rod 31 is fixed with a first screw rod 32. The end of the first screw rod 32 is rotatably mounted with a sleeve rod 33. Both ends of the sleeve rod 33 are slidably and telescopically mounted with a cross-shaped telescopic rod 34. The end of the cross-shaped telescopic rod 34 is fixed with a first section block 35. A second section block 36 is sleeved on the first screw rod 32, and the second section block 36 is rotatably connected to the first section block 35 through a connecting rod 37.

[0025] In this embodiment, an adjusting nut 39 is screwed on the outer wall of the first screw rod 32 to position one end of the second section block 36 on the first screw rod 32. An L-shaped strip 38 is fixedly connected to the end of the first section block 35. The adjusting nut 39 is tightened on the first screw rod 32 to fix the position of the second section block 36, thereby locking the fixed state of the paper tube. The L-shaped strip 38 directly contacts the paper tube to provide stable support.

[0026] In this embodiment, a base 4 is fixed at one end of the chassis 1, and a motor 5 is installed on the upper end of the base 4. The power output end of the motor 5 is connected to the power input end of the rotating rod 31. A first bevel gear 6 is welded on the outer wall of the rotating rod 31. A second bevel gear 7 is meshed and driven at the upper end of the first bevel gear 6. A second screw rod 8 is welded at the upper end of the second bevel gear 7. A glue adding box 9 rotatably connected to the second screw rod 8 is fixed on the upper end of the mounting plate 2. A lifting pressing plate 10 screwed to the second screw rod 8 is slidably mounted up and down on the inner wall of the glue adding box 9. A vertical plate 12 is fixedly connected to the upper end of the chassis 1. A glue spreading plate 13 is fixedly installed at the top of the vertical plate 12. The glue spreading plate 13 is communicated with the inner cavity of the glue adding box 9 through a diversion pipe 11. A plurality of spraying heads 14 are installed in communication at the lower end of the glue spreading plate 13. The motor 5 drives the second screw rod 8 to rotate through the meshing transmission of the first bevel gear 6 and the second bevel gear 7. The second screw rod 8 is screwed with the lifting pressing plate 10. Therefore, when the second screw rod 8 rotates, the lifting pressing plate 10 moves up and down in the glue adding box 9. A sealing strip fitting the inner wall of the box body is arranged around the lifting pressing plate 10. The up and down movement of the lifting pressing plate 10 is used to adjust the pressure of the glue in the glue adding box 9 to ensure that the glue can stably and continuously flow to the glue spreading plate 13 through the diversion pipe 11. The glue spreading plate 13 receives the glue from the glue adding box 9 through the diversion pipe 11 and evenly sprays the glue on the surface of the rotating paper tube through a plurality of spraying heads 14 at its lower end.

[0027] It should be noted that the motor 5 is specifically a stepper motor that can rotate forward and backward, with the model AM34HD0404-08. This stepper motor is controlled to rotate by a stepper driver. The stepper driver sends specific pulse signals to the stepper motor to achieve rotation. When the pulse signals sent by the stepper driver change, the rotation direction of the motor will also change accordingly, resulting in the reverse rotation of the motor.

[0028] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0029] During operation, the paper tube is fixed on the mounting plate 2 through the paper tube fixing mechanism. Specifically, the adjustable fixing component 3 uses the rotating rod 31 as the support shaft, and the expansion and contraction of the cross telescopic rod 34 is realized through the connecting rod 37 between the first section block 35 and the second section block 36, thereby realizing the adaptive fixation of paper tubes with different diameters. This design allows for a certain angle adjustment space when fixing the paper tube to adapt to different positions or slight deformations of the paper tube. The adjusting nut 39 is screwed tightly on the first screw rod 32 to fix the position of the second section block 36, thereby locking the fixed state of the paper tube. The L-shaped strip 38 is directly in contact with the paper tube to provide stable support. The motor 5 is installed on the base 4, and its power output end is connected to the rotating rod 31. Driven by the motor 5, the rotating rod 31 drives the paper tube to rotate. This rotating design enables the glue to be coated on the surface of the paper tube more evenly and quickly. In addition, the motor 5 also drives the second screw rod 8 to rotate through the meshing transmission of the first bevel gear 6 and the second bevel gear 7. The second screw rod 8 is threadedly connected with the lifting pressure plate 10. Therefore, when the second screw rod 8 rotates, the lifting pressure plate 10 moves up and down in the glue adding box 9. The periphery of the lifting pressure plate 10 is provided with a sealing strip that fits the inner wall of the box body. The up and down movement of the lifting pressure plate 10 is used to adjust the pressure of the glue in the glue adding box 9 to ensure that the glue can stably and continuously flow to the glue spreading plate 13 through the diversion pipe 11. The glue spreading plate 13 receives the glue from the glue adding box 9 through the diversion pipe 11 and evenly sprays the glue on the surface of the rotating paper tube through a plurality of groups of spraying heads 14 at its lower end. Since the paper tube continuously receives the glue from the spraying heads 14 during rotation, the glue can be evenly covered on the surface of the paper tube.
