Description

Technical Field

[0001] The invention belongs to the technical field of production and processing of breathable adhesive tapes, and in particular relates to a medical breathable adhesive tape winding device and a use method thereof. Background Art

[0002] In the modern medical field, medical breathable tape is a commonly used medical consumable, widely used in medical scenarios such as wound dressing, fixing dressings, and electrode patch pasting. It has good air permeability and can reduce the discomfort and allergic reactions caused by long-term skin coverage, so it is favored by medical staff and patients.

[0003] In the production process of medical breathable tape, winding is a key link. Among them, the coreless winder has unique advantages in the production of medical breathable tape. It can directly wind the tape into a coreless roll, which is very suitable for some scenarios that have high requirements for the compactness and space utilization of tape winding. Coreless winding can avoid the use of 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 winder can achieve a high winding speed and accuracy, which is suitable for large-scale and high-efficiency production. The tape rolls produced have a regular appearance and stable quality, which is convenient for subsequent packaging and transportation.

[0004] However, in the process of using a coreless winder to wind the tape, the inventor found that although the existing coreless winder can realize automatic winding of the tape, after the winding is completed, the winding is first stopped, and then the tape is cut and separated. Then, adhesive is affixed to the cut and separated tape, and then the tape ends are bonded and fixed by the adhesive by continuing to wind. After the bonding is completed, the tape roll is separated, and finally the subsequent tape is fed in and continued to be wound. In the overall process, especially in the link of winding completion switching, the winding link will be shut down, which reduces the overall winding efficiency and seriously affects the overall production efficiency.

[0005] Therefore, the existing structure and defects are studied and improved, and a medical breathable tape winding device and a use method are provided, in order to achieve a more practical purpose. Summary of the invention

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] Example 1, please refer to Figure 1 , Figure 2 and Figure 3A medical breathable adhesive tape winding device comprises a first conveying ring strip 2 and a second conveying ring strip 3, wherein a plurality of rotatable winding rollers 5 are arranged on one side of the first conveying ring strip 2, a plurality of detachable winding pressure plates 6 for pressing and fixing the adhesive tape 4 on the winding roller 5 are arranged on one side of the second conveying ring strip 3, a pressing groove 50 for placing the winding pressure plate 6 is arranged on the winding roller 5, the winding pressure plate 6 and the pressing groove 50 are detachably engaged with each other, the first conveying ring strip 2 and the second conveying ring strip 3 rotate synchronously in opposite directions, and during the cyclic rotation of the first conveying ring strip 2 and the second conveying ring strip 3, the winding pressure plate 6 and the corresponding pressing groove 50 can be engaged with each other first and then separated, and the first conveying ring strip 2 and the second conveying ring strip 3 are arranged in sequence at the positions close to each other with waiting areas 101 , winding area 102 and discharge area 103, the winding pressure plate 6 and the pressing groove 50 are separated in the waiting area 101, the winding pressure plate 6 and the pressing groove 50 are in a snap-connected state in the winding area 102, and the winding pressure plate 6 and the pressing groove 50 are separated after passing through the discharge area 103, the first conveying ring strip 2 is provided with a rotatable driving ring strip 7 for driving the winding roller 5 in the winding area 102 and the discharge area 103 to selectively rotate, the pressing groove 50 is provided with a cutting knife 54 that can move back and forth and is used for cutting and separating the tape 4, the discharge area 103 is also provided with a coating mechanism 8 for coating the surface of the tape 4 with adhesive, and the first conveying ring strip 2 located in the discharge area 103 is also provided with a rotatable top plate 22 for extruding and bonding the adhesive-coated tape 4.

[0038] The design of the first conveying ring 2, the second conveying ring 3, the winding roller 5 and the winding pressure plate 6, and with the cooperation of the driving ring 7 and the cutting knife 54, realizes the automatic winding of the tape 4 by the winding roller 5 and the automatic switching after the winding is completed. In the switching process, the machine does not stop and the winding of the tape 4 by the winding roller 5 is not affected, which fully improves the overall winding efficiency and changes the original winding method.

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

[0040] In this example, see 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 connected to the positioning groove for one-way rotation, and a counterweight block is also provided inside the winding roller 5. When the winding roller 5 is rotationally connected to the positioning groove, the counterweight block enables the pressing groove 50 to always remain in an upward position.

[0041] The design of the selective one-way rotation connection can ensure that when the winding roller 5 is winding and rewinding, the one-way rotation connection between the winding roller 5 and the first conveying ring strip 2 is used, so that the winding roller 5 will not reverse due to external force during the process of moving from the winding area to the winding area 102, resulting in the tape 4 being unable to be effectively bonded subsequently. After the unloading of the winding roller 5 is completed, the one-way rotation connection between the winding roller 5 and the first conveying ring strip 2 can be released, and under the action of the counterweight block, the pressure groove 50 can always remain in an upward state. Such a design can better separate the winding pressure plate 6 from the winding roller 5.

[0042] In this example, see Figure 1 , Figure 3 A plurality of fixedly connected positioning blocks 32 are provided on one side of the second conveying ring strip 3, the winding pressure plate 6 is made of a magnetically adsorbable material, a first electromagnet for adsorbing and fixing one end of the winding pressure plate 6 is provided in the positioning block 32, a clamping rod 61 is further provided at the bottom of the winding pressure plate 6, a clamping rod 61 is provided on one side of the pressing groove 50 and engaged with the clamping groove 52, and a second electromagnet for adsorbing and fixing the winding pressure plate 6 is further provided in the pressing groove 50.

[0043] The design of the first electromagnet can utilize magnetic force to achieve selective separation and connection between the winding pressure plate 6 and the second conveying ring 3, and there will be no squeezing between the winding roller 5 and the winding pressure plate 6 during the rotation of the first conveying ring 2 and the second conveying ring 3. At the same time, the design of the second electromagnet can utilize the second electromagnet to make the winding pressure plate 6 squeeze the tape 4 more firmly, and the design of the clamping rod 61 and the clamping groove 52 can prevent the winding pressure plate 6 from being taken away at the same time due to the clamping of the clamping rod 61 and the clamping groove 52 during discharging, thereby ensuring the overall stability.

[0044] In this example, see Figure 3 , Figure 4 The inner wall of the positioning groove is provided with a positioning ring groove 25, and a plurality of evenly distributed helical teeth 59 are provided in the positioning ring groove 25, and the helical teeth 59 are fixedly connected to the winding roller 5. An adjustment groove 26 is provided on the side wall of the positioning ring groove 25, and a non-return tooth 24 for sliding connection and preventing the helical teeth 59 from rotating in the opposite direction is provided in the adjustment groove 26, and a first hydraulic rod 27 for driving the non-return tooth 24 to reciprocate is provided in the adjustment groove 26. The design of the helical teeth 59, the non-return teeth 24 and the first hydraulic rod 27 realizes the selective one-way rotation connection of the winding roller 5.

[0045] In this example, see Figure 1 , Figure 2, further comprising a winding base 1, wherein one side of the winding base 1 is provided with a first conveying wheel 21 which is rotatable and used to drive the first conveying ring strip 2 to rotate, and one side of the winding base 1 is also provided with a second conveying wheel 31 which is rotatable and used to drive the second conveying ring strip 3 to rotate, and one side of the winding base 1 is provided with a conveying motor, and the conveying motor drives one of the first conveying wheels 21 to rotate, and the first conveying wheel 21 and the second conveying wheel 31 are meshedly connected by gears, and one side of the winding base 1 is also provided with a winding shaft 11, and the adhesive tape 4 is wound and sleeved on the winding shaft 11.

[0046] In this example, see Figure 1 , Figure 3 A limiting ring groove is provided on one side of the winding base 1, a driving groove is provided in the winding roller 5, a rotatable driving shaft 57 is provided in the driving groove, a reciprocating thread 56 is provided on the driving shaft 57, and a reciprocating slider 55 matching and connected with the reciprocating thread 56 is sleeved on the driving shaft 57, the reciprocating slider 55 is slidably connected with the driving groove, a cutting groove 51 connected with the driving groove is provided at the bottom of the pressing groove 50, the cutting knife 54 is slidably connected in the cutting groove 51, and the reciprocating slider 5 5 is fixedly connected to the cutting knife 54, a fixedly connected driving plate 58 is provided in the limiting ring groove between the waiting area 101 and the winding area 102, a plurality of driving wheels 53 are provided in the limiting ring groove, the driving wheels 53 are fixedly connected to the corresponding driving shafts 57, and when the driving wheels 53 pass through the driving plates 58, the friction between the driving wheels 53 and the driving plates 58 drives the driving wheels 53 to rotate, so that when the winding roller 5 moves to the winding area 102, the cutting knife 54 returns to the 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 pressure plate 6 to be engaged and connected with the pressing groove 50. 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 motion of the cutting knife 54 is realized. Moreover, since the winding pressure plate 6 is in an extruded state when the cutting knife 54 is cutting, the cutting is more stable.

[0048] In this example, see Figure 1 , Figure 2The first conveying ring strip 2 is provided with a first driving wheel 74 and a second driving wheel 71 which are horizontally distributed, and a third driving wheel 73 which can move up and down is provided 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, and 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. A second hydraulic rod 72 which is fixedly connected is provided on the winding base 1, and the second hydraulic rod 72 drives the second driving wheel 71 to reciprocate in the horizontal direction. A tensioning groove is provided on one side of the winding base 1, and a tensioning block which is slidably connected is provided in the tensioning groove, and a tensioning spring 75 for driving the tensioning block to automatically squeeze is provided in the tensioning groove, and the third driving wheel 73 is rotatably connected with the tensioning block, and a driving motor is provided in the winding base 1, and the driving motor drives the first driving wheel 74 to rotate.

[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 discharge area 103 through the extension and retraction of the second hydraulic rod 72. The design of the tensioning spring 75 enables the driving ring 7 to always remain in a tensioned state during the extension and retraction of the second hydraulic rod 72.

[0050] In this example, see Figure 1 , Figure 5 The coating mechanism 8 includes a coating roller 81 and an extrusion plate 82. A first fixed plate 83 is provided on one side of the winding base 1. A third hydraulic rod 85 is fixedly connected to the first fixed plate 83. A coating frame is fixedly connected at the end of the third hydraulic rod 85. A rotatably connected coating roller 81 is provided in the coating frame. An adhesive is provided on the surface of the coating roller 81. The extrusion plate 82 is located in the second conveying ring 3. A second fixed plate 84 for fixing the extrusion plate 82 is provided 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 rotatably connected rotating shaft 23 is provided on one side of the winding base 1 , the top plate 22 is fixedly connected to the rotating shaft 23 , and a torsion spring connected to the rotating shaft 23 is provided on the winding base 1 .

[0052] The design of the torsion spring can ensure that the top plate 22 always maintains the squeezing force on the adhesive tape 4 and the top plate 22 does not affect the overall stable operation.

[0053] When using this application:

[0054] When the winding roller 5 in the winding area is about to complete winding, the first conveying ring strip 2 and the second conveying ring strip 3 are controlled to rotate synchronously, so that the winding rollers 5 in the waiting area 101, the winding area and the discharge 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 discharge area 103, and the movement speed is controlled to be the same as the winding speed;

[0055] When in motion, first control the first electromagnet in the winding roller 5 in the waiting area 101 to close, and control the second electromagnet to open, and the winding pressure plate 6 automatically falls and fits in the pressing groove 50 under the action of gravity and magnetic force, and the clamping rod 61 is clamped with the clamping groove 52. With the movement of the winding roller 5, the driving wheel 53 and the driving plate 58 rub against each other, so that the driving wheel 53 rotates, driving the driving shaft 57 to rotate, and under the action of the reciprocating thread 56, the cutting knife 54 is driven to automatically reciprocate, thereby realizing the automatic cutting of the adhesive tape 4 after the winding pressure plate 6 is pressed. Before the winding roller 5 in the waiting area 101 moves to the winding area, the adhesive tape 4 has been cut, and after the driving wheel 53 and the driving plate 58 are separated, the cutting knife 54 returns to the initial position;

[0056] When the winding roller 5 in the waiting area 101 moves to the winding area, that is, the winding roller 5 contacts and abuts against the driving ring strip 7, the rotation of the first conveying ring strip 2 and the second conveying ring strip 3 is stopped, and the driving ring strip 7 is controlled to continue to rotate, driving the winding roller 5 to rotate, so that the winding roller 5 in the winding area automatically winds the adhesive tape 4. During winding, due to the presence of the non-return teeth 24, the winding roller 5 in the discharge area 103 will not rotate in the opposite direction. Therefore, the winding of the winding roller 5 will automatically pull the cut and separated adhesive tape 4 away from the winding roller 5, so that the adhesive tape 4 on one side of the winding pressure plate 6 is automatically separated, and at the same time will not affect the winding of the original adhesive 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 discharge area 103 synchronously. At this time, the third hydraulic rod 85 is controlled to drive the coating roller 81 to move upward, so that the coating roller 81 and the extrusion plate 82 squeeze the end of the tape 4 to a limit; then the second hydraulic rod 72 is controlled 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. With the rotation of the winding roller 5 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 tape 4 After the automatic winding is completed, the driving ring strip 7 is controlled to restore the initial position, and the second electromagnet is controlled to be closed. At this time, the tape 4 at the winding roller 5 can be taken out. Due to the engagement of the clamping rod 61 and the clamping groove 52, the winding pressure plate 6 will not be driven together during the process of taking out the tape 4; after taking it out, the first hydraulic rod 27 is controlled to drive the check tooth 24 to be recovered, and the winding roller 5 in the winding area can automatically keep the pressure groove 50 facing upward under the action of the gravity of the counterweight block. Then, the first electromagnet can be controlled to use the first electromagnet to adsorb and fix one end of the winding pressure plate 6, so that the winding pressure plate 6 is automatically separated from the pressure groove 50; and with the subsequent rotation, it moves to the waiting area 101 again; while the winding area is operating, the winding area 102 also operates synchronously without affecting each other.
