[0002] Kraft paper tapes are divided into wet kraft paper tapes and water-free kraft paper tapes, which can be printed according to requirements, with added screen lines. The water-free kraft paper tape is based on high-grade kraft paper, with single-sided film coating with release agent or direct caulking anti-sticking treatment without film coating, and is made by coating oil-based glue or hot melt glue on the back. The wet kraft paper tape is coated with modified starch glue after film coating treatment.
[0003] A tape wetting machine, usually referring to a wet kraft paper tape machine, is a device widely used in the packaging industry. Such machines make the kraft paper tape sticky through the method of applying water or wetting water, so as to facilitate carton sealing or packing.
[0004] The existing structure for clamping the tape inside the wetting machine is usually a fixed structure design, which results in that the wetting machine itself can only adapt to a single size of tape for clamping. When it is necessary to use tapes of other sizes, a wetting machine adapted to the tape size needs to be equipped for use, resulting in certain limitations in the use of the existing wetting machine. Summary of the Utility Model

Among them, by driving the adjusting part, the two limiting clamping plates are controlled to move closer or farther away in a relative track.
[0009] As described above, by driving the adjusting member to control the relative movement of the two limiting clamping plates to approach or move away from each other, the distance between the limiting clamping plates can be adjusted according to the size of the tape roll, so as to adapt to the clamping of tape rolls of different sizes, solving the problem that the structure for clamping the tape inside the existing wet paper machine is usually a fixed structure design, resulting in the wet paper machine itself can only adapt to a single size of tape for clamping, with certain limitations in use.

[0030] Please refer to Figures 1 to 5 , which shows the tape clamping device in the embodiment of the present utility model, including a clamping assembly 1, a top cover assembly 3 arranged on one side of the clamping assembly 1, a turning shaft 2 arranged between the clamping assembly 1 and the top cover assembly 3, and a clamping component 4 arranged in the clamping assembly 1 for clamping the tape. The clamping assembly 1 includes a fixed table 11 at the bottom, fixed side plates 12 extending outward along both sides of the fixed table 11. The clamping component 4 includes an adjusting member 41 movably arranged between the two fixed side plates 12 and close to one side of the turning shaft 2, and at least two limiting clamping plates 42 sleeved on the adjusting member 41 for clamping the tape. Among them, by driving the adjusting member 41, the two limiting clamping plates 42 are controlled to approach or move away relatively along a track.
[0031] Furthermore, the adjusting member 41 includes movable shafts 411 respectively embedded in the two fixed side plates 12, a driving screw 412 at least partially embedded in the two movable shafts 411, and an adjusting part 413 sleeved in the middle of the driving screw 412. The clamping assembly 1 further includes a supporting arc plate 13 and a material guiding plate 14 which are sequentially arranged on the fixed table 11 and away from one side of the turning shaft 2 for guiding the tape to be exported. Among them, an adapting groove is also arranged at the position where the limiting clamping plate 42 is close to the supporting arc plate 13, so that the limiting clamping plate 42 can be supported by the adjusting member 41, the positioning rod 15 and the supporting arc plate 13 at the same time to ensure the stability of the limiting clamping plate 42. A positioning rod 15 is arranged in the middle of the two fixed side plates 12 and used for limiting the movement track of the limiting clamping plate 42. Limiting grooves 16 for accommodating at least part of the top cover assembly 3 are oppositely arranged on the two fixed side plates 12. The top cover assembly 3 includes a side extension plate 31 connected to the turning shaft 2, a top plate 32 arranged on the side of the side extension plate 31 away from the turning shaft 2, a movable plate 33 movably arranged on the side of the top plate 32 away from the side extension plate 31, and a resilient positioning member arranged on the side of the top plate 32 facing the clamping assembly 1. The resilient positioning member includes at least two elastic parts 34 arranged between the top plate 32 and the fixed table 11. In some alternative embodiments, the elastic parts 34 can be springs, and a guiding rod 35 with one side connected to the top plate 32 and the other side embedded in the limiting groove 16. A transmission groove 43 adapted to the driving screw 412 is arranged on the side of the limiting clamping plate 42 close to the adjusting member 41, and a positioning groove 44 for accommodating the positioning rod 15 is arranged on the side of the limiting clamping plate 42 close to the fixed table 11. A limiting pressing cover 36 opposite to the accommodating space is arranged on the side of the top plate 32 close to the movable plate 33.
[0032] In the specific implementation, the operator can first lift the top cover assembly 3 along the movable plate 33 to make it flip open along the flip axis 2. In some optional embodiments, a locking structure can be set at the movable plate 33 and the fixed platform 11 to ensure the stability of the structure between the top cover assembly 3 and the clamping assembly 1 after the subsequent closing. After that, the operator can place the tape roll in the accommodating space formed by the positioning rod 15, the supporting arc plate 13 and the two limiting clamps 42, and guide the unwinding end of the tape roll to sequentially fit the supporting arc plate 13 and the guide plate 14 to the water tank of the tape wet water machine. It can be understood that the tape clamping device of the present application is located behind the water tank of the tape wet water machine. Next, in order to ensure the stability of the tape roll at the clamping assembly 4 and avoid the axial deviation of the tape roll during the subsequent pulling of the tape roll, the operator can control the adjustment of the limiting clamp 42 by driving the adjusting member 41. Specifically, the operator can drive the adjusting portion 413 to rotate axially to The fixedly connected driving screw 412 rotates axially in the movable shaft 411, and at the same time, the driving screw 412 drives the limiting clamp 42 to rotate accordingly, but the limiting clamp 42 is limited by the positioning rod 15, so that the output state that originally rotates with the driving screw 412 is adjusted to the transmission groove 43 on the driving screw 412 along its axial movement in the form of thread transmission. It should be noted that the driving screw 412 is composed of two opposite screw sections and the two screw sections are connected by an adjusting portion 413, and the threads on the two screw sections are relatively arranged, so that when the driving screw 412 is rotated subsequently, the limiting clamp 42 sleeved on the outer surface of the screw can respectively show a relatively close or distant movement trajectory, so that the spacing between the limiting clamps 42 can be adjusted according to the size of the tape roll to adapt to the clamping of tape rolls of different sizes, wherein the adjusting portion 413 is rotated clockwise to close the limiting clamp 42, and vice versa to control the expansion of the limiting clamp 42.
[0033] Further, after the tape roll is installed in the clamping component 4, the operator can close the top cover assembly 3. During this process, the tape roll is pressed and fixed through the limiting gland 36 arranged on one side of the top cover assembly 3 facing the clamping component 4. Among them, the limiting gland 36 is composed of an arc plate and at least two spring columns for connecting the arc plate and the top cover 32. When the top cover assembly 3 is closing, the arc plate will initially contact and fit with the surface of the tape roll. After that, during the continuous closing movement of the top cover assembly 3, the two spring columns on the arc plate are compressed to form the pressing and fixing of the tape roll, further ensuring the stability of the tape roll. At the same time, during the use of the tape roll, its outer diameter length will continuously decrease. During this process, the two spring columns on the arc plate can enable the arc plate to adaptively change according to the outer diameter of the tape roll and always ensure the abutment against the outer surface of the tape roll, further ensuring the stability of the tape roll during use. In addition, in some alternative embodiments of the present invention, in order to avoid the assistance limitation of the arc plate on the tape unwinding process, a plurality of ball or roller structures can be additionally provided at the contact part between the arc plate and the tape roll to reduce the friction between the arc plate and the surface of the tape roll and ensure the smoothness of the tape unwinding process.
[0034] In summary, by axially rotating the adjustment part 413 to drive the driving screw 412 fixedly connected thereto to axially rotate in the movable shaft 411. At the same time, the driving screw 412 drives the limiting clamping plate 42 to rotate accordingly. However, the limiting clamping plate 42 is limited by the positioning rod 15, so that the output state originally following the rotation of the driving screw 412 is adjusted to the form that the transmission groove 43 axially moves along the driving screw 412 in a threaded transmission manner, realizing the adjustable distance between the limiting clamping plates 42 corresponding to the size of the tape roll to adapt to the clamping of tape rolls of different sizes, and solving the problem that the structure for clamping the tape inside the existing wet paper machine is usually a fixed structure design, resulting in the wet paper machine itself can only adapt to a single-size tape for clamping, having certain limitations in use.
