Description

Technical Field

[0001] The present invention belongs to the technical field of production and processing of breathable tapes, and particularly relates to a winding device for medical breathable tapes and a usage method thereof. Background Art

[0002] In the modern medical field, medical breathable tapes are a commonly used medical consumable, widely used in medical scenarios such as wound dressing, fixing dressings, and electrode patch sticking. They have good breathability, can reduce the discomfort and allergic reactions caused by the skin being covered for a long time, and are thus favored by medical staff and patients.

[0003] In the production process of medical breathable tapes, winding is a key link. Among them, a coreless winding machine has unique advantages in the production of medical breathable tapes. It can directly wind the tape into a coreless roll shape, which is very suitable for some scenarios with high requirements for the compactness and space utilization of tape winding. Coreless winding can avoid using paper cores or plastic cores, which not only reduces costs, but also reduces material waste and subsequent processing procedures. At the same time, the coreless winding machine can achieve high winding speed and accuracy, is suitable for large-scale and high-efficiency production, and the produced tape rolls have regular appearance and stable quality, which is convenient for subsequent packaging and transportation.

[0004] However, during the process of winding the tape using a coreless winding machine, the inventor found that although the existing coreless winding machine realizes the automatic winding of the tape, after the winding is completed, the winding stops first, then cutting and separating are carried out, then an adhesive is pasted on the cut and separated tape, and then through continuous winding, the adhesive bonds and fixes the end of the tape. After the bonding is completed, the tape roll is separated, and finally the subsequent tape is sent in and continuous winding is carried out. In the overall process, especially in the process of switching after winding is completed, the winding process will stop, reducing the overall winding efficiency and seriously affecting the overall production efficiency.

[0005] Therefore, research and improvement are carried out on the existing structure and deficiencies, and a winding device for medical breathable tapes and a usage method thereof are provided, in order to achieve a more practical purpose. Summary of the Invention

[0037] Example 1, please refer to Figure 1 、 Figure 2 and Figure 3, A medical breathable tape winding device, comprising a first conveying ring strip 2 and a second conveying ring strip 3. A plurality of rotatable winding rollers 5 are provided on one side of the first conveying ring strip 2. A plurality of separable winding pressing plates 6 for pressing and fixing the tape 4 on the winding rollers 5 are provided on one side of the second conveying ring strip 3. A pressing groove 50 for placing the winding pressing plate 6 is provided on the winding roller 5. The winding pressing plate 6 and the pressing groove 50 are detachably and snap-fitted. The first conveying ring strip 2 and the second conveying ring strip 3 rotate synchronously and in opposite directions. During the cyclic rotation of the first conveying ring strip 2 and the second conveying ring strip 3, the winding pressing plate 6 and the corresponding pressing groove 50 can be first snap-fitted and then separated. The areas where the first conveying ring strip 2 and the second conveying ring strip 3 are close to each other are successively provided with a waiting area 101, a winding area 102, and a discharging area 103. The winding pressing plate 6 and the pressing groove 50 are separated in the waiting area 101, the winding pressing plate 6 and the pressing groove 50 are in a snap-fitted connection in the winding area 102, and the winding pressing plate 6 and the pressing groove 50 are separated after passing through the discharging area 103. A driving ring strip 7 that is rotatable and used to drive the winding rollers 5 in the winding area 102 and the discharging area 103 to selectively rotate is provided inside the first conveying ring strip 2.

A top plate 22 that is rotatable and used for pressing and bonding and fixing the tape 4 after coating the adhesive is further provided inside the first conveying ring strip 2 located in the discharging area 103.

[0038] The designs of the first conveying ring strip 2, the second conveying ring strip 3, the winding rollers 5, and the winding pressing plates 6, and with the cooperation of the driving ring strip 7 and the cutting knife 54, the automatic winding of the tape 4 by the winding rollers 5 and the automatic switching after the winding is completed are realized. And during the switching process, there is no need to stop the machine, which does not affect the winding of the tape 4 by the winding rollers 5, fully improving the overall winding efficiency and changing the original winding method.

[0039] The driving ring strip 7 can realize the selective rotation of the winding rollers, while the coating mechanism 8 and the top plate 22 can realize the automatic bonding and fixing of the tape 4 after cutting.

[0040] In this embodiment, please refer to Figure 1 、 Figure 2 , A plurality of positioning grooves are provided on the first conveying ring strip 2. One end of the winding roller 5 is selectively and unidirectionally rotatably connected to the positioning groove, and a counterweight block is further provided inside the winding roller 5. When the winding roller 5 is rotatably connected to the positioning groove, the counterweight block makes the pressing groove 50 always keep upward.

[0041] The design of the selective one-way rotational connection enables the winding roller 5, during the winding process, to prevent reverse rotation due to external forces when moving from the winding area to the coiling area 102 through the one-way rotational connection between the winding roller 5 and the first conveying ring strip 2, which may otherwise cause ineffective bonding of the tape 4 later. After the discharging of the winding roller 5 is completed, the one-way rotational connection between the winding roller 5 and the first conveying ring strip 2 can be released, and under the action of the counterweight, the pressing groove 50 always remains in an upward state. Such a design can better separate the winding pressing plate 6 from the winding roller 5.

[0042] In this embodiment, please refer to Figure 1 、 Figure 3 On one side of the second conveying ring strip 3, there are a plurality of fixedly connected positioning blocks 32.

Inside the pressing groove 50, there is also a second electromagnet for adsorbing and fixing the winding pressing plate 6.

[0043] The design of the first electromagnet can utilize magnetic force to achieve selective separation and connection between the winding pressing plate 6 and the second conveying ring strip 3, and it can also prevent extrusion between the winding roller 5 and the winding pressing plate 6 during the rotation of the first conveying ring strip 2 and the second conveying ring strip 3. At the same time, the design of the second electromagnet can use the second electromagnet to press the tape 4 more firmly by the winding pressing plate 6. The design of the clamping rod 61 and the clamping groove 52 can ensure that during discharging, due to the engagement of the clamping rod 61 and the clamping groove 52, the winding pressing plate 6 will not be taken away simultaneously, thus ensuring the overall stability.

[0044] In this embodiment, please refer to Figure 3 、 Figure 4 On the inner wall of the positioning groove, there is a positioning ring groove 25. Inside the positioning ring groove 25, there are a plurality of uniformly distributed helical teeth 59, which are fixedly connected to the winding roller 5. On the side wall of the positioning ring groove 25, there is an adjustment groove 26.

The design of the helical teeth 59, the check tooth 24, and the first hydraulic rod 27 realizes the selective one-way rotational connection of the winding roller 5.

[0045] In this embodiment, please refer to Figure 1 、 Figure 2, further comprising a winding base 1, on one side of the winding base 1 there is a rotatable first conveying wheel 21 for driving the first conveying ring strip 2 to rotate, on one side of the winding base 1 there is also a rotatable second conveying wheel 31 for driving the second conveying ring strip 3 to rotate, on one side of the winding base 1 there is a conveying motor, the conveying motor drives one of the first conveying wheels 21 to rotate, the first conveying wheel 21 and the second conveying wheel 31 are connected by gear meshing, on one side of the winding base 1 there is also a winding shaft 11, and the tape 4 is wound around the winding shaft 11 in a coiled state.

[0046] In this embodiment, please refer to Figure 1 、 Figure 3 , on one side of the winding base 1 there is a limiting ring groove, inside the winding roller 5 there is a driving groove, inside the driving groove there is a rotatable driving shaft 57, on the driving shaft 57 there is a reciprocating thread 56, and a reciprocating slider 55 that is connected in a matching manner with the reciprocating thread 56 is sleeved on the driving shaft 57, the reciprocating slider 55 is slidably connected to the driving groove, at the bottom of the pressing groove 50 there is a cutting groove 51 communicating with the driving groove, the cutting knife 54 is slidably connected in the cutting groove 51, the reciprocating slider 55 is fixedly connected to the cutting knife 54, inside the limiting ring groove located between the waiting area 101 and the winding area 102 there is a fixedly connected driving plate 58, inside the limiting ring groove there are a plurality of driving wheels 53, the driving wheels 53 are fixedly connected to the corresponding driving shafts 57, and when the driving wheel 53 passes through the driving plate 58, the friction between the driving wheel 53 and the driving plate 58 drives the driving wheel 53 to rotate, so that when the winding roller 5 moves to the winding area 102, the cutting knife 54 returns to its initial position and the cutting is completed.

[0047] The design of the reciprocating thread 56, the driving wheel 53 and the driving plate 58 enables the winding pressing plate 6 to be snap - connected to the pressing groove 50, and as the winding roller 5 moves, the driving wheel 53 rotates on the driving plate 58, thereby driving the driving shaft 57 to rotate. Under the action of the reciprocating thread 56, the reciprocating movement of the cutting knife 54 is realized. Moreover, since the winding pressing plate 6 is in an extrusion state when the cutting knife 54 cuts, the cutting is more stable.

[0048] In this embodiment, please refer to Figure 1 、 Figure 2, a first driving wheel 74 and a second driving wheel 71 horizontally distributed are arranged inside the first conveying ring strip 2. A third driving wheel 73 capable of moving up and down is arranged between the first driving wheel 74 and the second driving wheel 71. The first driving wheel 74, the second driving wheel 71 and the third driving wheel 73 drive the driving ring strip 7 to rotate. The first driving wheel 74 is located in the winding area 102, and the second driving wheel 71 is located in the discharging area 103.

[0049] The design of the first driving wheel 74, the second driving wheel 71 and the third driving wheel 73 realizes the selective driving of the winding roller 5 in the discharging area 103 through the telescopic movement of the second hydraulic rod 72. The design of the tensioning spring 75 enables the driving ring strip 7 to always maintain a tensioned state during the telescopic movement of the second hydraulic rod 72.

[0050] In this embodiment, please refer to Figure 1 , Figure 5 , the coating mechanism 8 includes a coating roller 81 and an extrusion plate 82.

An adhesive is arranged on the surface of the coating roller 81. The extrusion plate 82 is located inside the second conveying ring strip 3. A second fixing plate 84 for fixedly connecting the extrusion plate 82 is arranged on one side of the winding base 1. The extrusion plate 82 is located directly above the coating roller 81.

[0051] In this embodiment, a rotating shaft 23 is rotatably connected to one side of the winding base 1. The top plate 22 is fixedly connected to the rotating shaft 23. A torsion spring connected to the rotating shaft 23 is arranged on the winding base 1.

[0052] The design of the torsion spring enables the top plate 22 to always maintain a pressing force on the tape 4 and does not affect the overall stable operation of the top plate 22.

[0053] When this application is in use:

[0054] When the winding roller 5 in the winding area is about to finish winding, control the first conveying ring strip 2 and the second conveying ring strip 3 to rotate synchronously, so that the winding rollers 5 in the waiting area 101, the winding area and the discharging area 103 move synchronously. The winding roller 5 in the waiting area 101 moves to the winding area, and the winding roller 5 in the winding area moves to the discharging area 103, and control the moving speed to be the same as the winding speed;

[0055] During the movement, first control the first electromagnet in the winding roller 5 in the waiting area 101 to turn off, and control the second electromagnet to turn on. Under the action of gravity and magnetic force, the winding pressing plate 6 automatically drops and fits into the pressing groove 50, and the clamping rod 61 is engaged with the clamping groove 52. As the winding roller 5 moves, the driving wheel 53 rubs against the driving plate 58, causing the driving wheel 53 to rotate, driving the driving shaft 57 to rotate. Under the action of the reciprocating thread 56, the cutting knife 54 is driven to move automatically back and forth, realizing the automatic cutting of the tape 4 after the winding pressing plate 6 is pressed. Before the winding roller 5 in the waiting area 101 moves to the winding area, the tape 4 has been cut, and after the driving wheel 53 is separated from the driving plate 58, the cutting knife 54 returns to its initial position;

[0056] When the winding roller 5 in the waiting area 101 moves to the winding area, that is, when the winding roller 5 contacts and abuts against the driving ring strip 7, stop the rotation of the first conveying ring strip 2 and the second conveying ring strip 3 at the same time, and control the driving ring strip 7 to continue to rotate, driving the winding roller 5 to rotate, so that the winding roller 5 in the winding area automatically winds the tape 4. During the winding, due to the existence of the check teeth 24, the winding roller 5 in the discharging area 103 will not rotate in the reverse direction. Therefore, the winding of the winding roller 5 will automatically pull the cut and separated tape 4 away from the winding roller 5, so that the tape 4 on one side of the winding pressing plate 6 is automatically separated, and at the same time, it will not affect the original winding of the tape 4;

[0057] When the winding roller 5 in the waiting area 101 moves to the winding area, the winding roller 5 in the original winding area also moves to the discharging area 103 synchronously. At this time, control the third hydraulic rod 85 to drive the coating roller 81 to move upward, so that the coating roller 81 and the pressing plate 82 limit the extrusion of the end of the tape 4; then control the second hydraulic rod 72 to drive the second driving wheel 71 to move, so that the driving ring strip 7 moves to the winding roller 5 in the winding area. At this time, the driving ring strip 7 automatically drives the winding roller 5 in the winding area to rotate, so that the winding roller 5 in the winding area can automatically drive the remaining tape 4 to automatically wind, and the adhesive on the surface of the coating roller 81 can be automatically coated on the tape 4. As the winding roller 5 rotates, and under the extrusion of the top plate 22, the end of the tape 4 can be automatically bonded and fixed. At this time, the automatic winding of the tape 4 is completed. Then control the driving ring strip 7 to return to the initial position, and control the second electromagnet to turn off. At this time, the tape 4 roll at the winding roller 5 can be taken out. Due to the engagement of the clamping rod 61 and the clamping groove 52, during the process of taking out the tape 4, the winding pressing plate 6 will not be driven together; after taking out, control the first hydraulic rod 27 to drive the check tooth 24 to retract. Under the action of the gravity of the counterweight block, the winding roller 5 in the winding area can automatically keep the pressing groove 50 facing upward. Then, the first electromagnet can be controlled to adsorb and fix one end of the winding pressing plate 6 by using the first electromagnet, so that the winding pressing plate 6 is automatically separated from the pressing groove 50; and with the subsequent rotation, it moves to the waiting area 101 again; during the operation of the winding area, the winding area 102 also operates synchronously without affecting each other.

Control the rotation speeds of the first conveying ring strip 2 and the second conveying ring strip 3, so that the moving speed of the winding roller 5 is the same as the winding speed of the winding roller 5. At this time, the first conveying ring strip 2 and the tape 4 are in a relatively static state. Therefore, the winding pressing plate 6 in the waiting area 101 can be separated from the second conveying ring strip 3, and the connection between the winding pressing plate 6 and the pressing groove 50 can be engaged. During the movement, control the cutting knife 54 to cut and separate the tape 4. When the winding roller 5 in the waiting area 101 moves to the winding area, the cutting knife 54 has completed cutting, and the driving ring strip 7 drives the winding roller 5 to rotate, so that the winding roller 5 in the winding area 102 can automatically rotate and wind;
