Description

Technical Field

[0001] This utility model relates to the field of winding technology, specifically a dual-station dressing winding device. Background Technology

[0002] As a critical first-aid supply, combat trauma dressings have strict requirements for roll quality during production, storage, and transportation. Combat trauma dressings need to be designed in various width specifications according to different injuries and emergency scenarios. For example, wide dressings (usually 30cm-50cm wide) are used for large-area wounds on the body surface, while narrow dressings (usually 10cm-20cm wide) are used for the extremities and joints to meet diverse emergency needs.

[0003] Currently, most of the winding equipment used in the industry for combat trauma first aid dressings is a single-station structure with limited winding width adjustment capabilities. On the one hand, existing single-station winding equipment can only wind one roll of dressing at a time. In emergency production and bulk stocking scenarios for combat trauma first aid supplies, the winding efficiency is low, making it difficult to quickly respond to the demand for large-scale emergency supplies. On the other hand, the winding mechanism of traditional winding equipment is mostly designed with a fixed width, or can only achieve a small range of width adjustment (usually no more than 15cm). When it is necessary to switch to different width specifications of dressings for winding, core components such as the winding roller and the limiting baffle need to be disassembled and replaced. This is not only cumbersome and time-consuming, but also prone to winding alignment deviations due to component disassembly and assembly errors, resulting in problems such as dressing edge wrinkles and loose winding, affecting the subsequent storage and use of the dressing.

[0004] In addition, combat trauma first aid dressings have high requirements for the stability of the winding process. Existing equipment often experiences tension fluctuations during the width adjustment process, resulting in uneven roll diameters of the same dressing and further reducing the quality of the dressing winding.

[0005] Therefore, it is necessary to provide a dual-station dressing take-up device to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a dual-station dressing winding device to solve the problems mentioned in the background technology.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a dual-station dressing rewinding device for rewinding several dressing rolls on a winding frame, including a worktable, on which two baffles are fixedly connected, and a first guide roller, a second guide roller, a guide post and a guide rod are installed between the baffles. The first guide roller is located in front of the second guide roller and is horizontal, the guide post is located directly above the second guide roller, and the guide rod is located directly below the second guide roller. Several limiting blocks are slidably connected on the second guide roller, the guide post and the guide rod, and the dressing roll to be rewinded is located between two adjacent limiting blocks.

[0008] Furthermore, the bottom of the guide rod has several protrusions evenly distributed along its length. The limiting block has a guide hole that matches the guide post, a center hole that matches the second guide roller, and a through cavity that matches the guide rod. A protrusion is elastically and telescopically connected inside the through cavity.

[0009] Furthermore, the cross-section of the protrusion is an isosceles triangle with its vertex located directly above.

[0010] Furthermore, the through cavity extends downward to form a movable cavity, and a stepped surface is formed between the through cavity and the movable cavity. A portion of the protrusion is confined within the stepped surface. The movable cavity contains a spring piece, one end of which abuts against the bottom of the protrusion, and the other end abuts against the bottom of the movable cavity.

[0011] Furthermore, a column is fixedly connected to the top front of the workbench, and a placement column is fixedly connected to one side of the column, the height of which is higher than the first guide roller.

[0012] Furthermore, a belt drive unit and a positioning seat are installed on one side of the workbench. The belt drive unit includes a motor and an output shaft installed inside the workbench. The motor transmits power to the output shaft via a belt. The output shaft is located behind the second guide roller. The positioning seat is concentrically arranged with the output shaft. A winding rod is installed between the positioning seat and the output shaft.

[0013] Furthermore, the positioning seat is elastically telescopically connected with a movable column, and the end of the movable column near the positioning seat has an insertion hole, and the end away from the movable column has an extension that penetrates the positioning seat. The positioning seat has a sliding cavity, and a spring is installed in the sliding cavity. The spring is nested in the part of the extension located in the sliding cavity. One end of the spring abuts against the movable column, and the other end abuts against the bottom of the sliding cavity.

[0014] Furthermore, one end of the winding rod is a positioning end that matches the insertion hole, and the other end is a locking end with a square cross-sectional area. The output shaft has a slot that matches the locking end. The middle part of the winding rod is a mounting part, and the cross-sectional area of ​​the mounting part is a polygon with at least six sides.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a dual-station dressing rewinding device. This device sets several limiting blocks on the guide rod. By adjusting the distance between two adjacent limiting blocks to be consistent with the width of the dressing roll, the tape pulled out from the dressing roll can be restricted between the two limiting blocks, which improves the efficiency of replacement. At the same time, it avoids the problem of dressing edge wrinkles and loose winding caused by component disassembly and assembly errors, which affect the subsequent storage and use effect of the dressing. By providing a protrusion at the bottom of the guide rod, which matches the protrusion inside the limiting block, the limiting block can be limited between the two protrusions. At the same time, under the action of the spring sheet, the protrusion can elastically extend and retract, making the position adjustment of the limiting block more flexible. By designing the mounting part of the winding bar into a polygonal shape, the friction of the dressing roll during winding can be increased, preventing the winding bar from spinning freely when rotating.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] like Figure 1-7 As shown, the present invention provides a technical solution: a dual-station dressing rewinding device for rewinding several dressing rolls 13 on a winding frame 14, including a workbench 1, on which two baffles 7 are fixedly connected, and between the baffles 7 are a first guide roller 8, a second guide roller 9, a guide post 10 and a guide rod 12. The first guide roller 8 is located in front of the second guide roller 9 and is horizontal, the guide post 10 is located directly above the second guide roller 9, and the guide rod 12 is located directly below the second guide roller 9. Several limiting blocks 11 are slidably connected to the second guide roller 9, the guide post 10 and the guide rod 12, and the dressing roll 13 to be rewinded is located between two adjacent limiting blocks 11.

[0021] The bottom of the guide rod 12 has several protrusions 121 evenly distributed along its length. The limiting block 11 has a guide hole 111 that matches the guide post 10, a center hole 112 that matches the second guide roller 9, and a through cavity 113 that matches the guide rod 12. A protrusion 15 is elastically and telescopically connected inside the through cavity 113.

[0022] The cross-section of bump 15 is an isosceles triangle with its vertex located directly above.

[0023] The through cavity 113 extends downward to form a movable cavity 114. A stepped surface is formed between the through cavity 113 and the movable cavity 114. A portion of the protrusion 15 is confined within the stepped surface. The movable cavity 114 contains a spring piece 16. One end of the spring piece 16 abuts against the bottom of the protrusion 15, and the other end abuts against the bottom of the movable cavity 114.

[0024] A column 2 is fixedly connected to the top front of the workbench 1, and a placement column 3 is fixedly connected to one side of the column 2. The height of the placement column 3 is higher than that of the first guide roller 8.

[0025] A belt drive unit 4 and a positioning seat 6 are installed on one side of the workbench 1. The belt drive unit 4 includes a motor and an output shaft 41 installed in the workbench 1. The motor transmits power to the output shaft 41 via a belt. The output shaft 41 is located behind the second guide roller 9. The positioning seat 6 is concentrically arranged with the output shaft 41. A winding rod 5 is installed between the positioning seat 6 and the output shaft 41.

[0026] The positioning base 6 is elastically telescopically connected with a movable column 17. The movable column 17 has an insertion hole 171 at one end near the positioning base 6 and an extension 172 that penetrates the positioning base 6 at the other end. The positioning seat 6 has a sliding cavity 61, and a spring 18 is provided in the sliding cavity 61. The spring 18 is nested in the part of the extension 172 located in the sliding cavity 61. One end of the spring 18 abuts against the movable column 17, and the other end abuts against the bottom of the sliding cavity 61.

[0027] One end of the winding rod 5 is a positioning end 51 that matches the insertion hole 171, and the other end is a locking end 53 with a square cross-sectional area. The output shaft 41 has a slot that matches the locking end 53. The middle part of the winding rod 5 is a mounting part 52, and the cross-sectional area of ​​the mounting part 52 is a polygon with at least six sides.

[0028] In one embodiment, the operating principle of the device

[0029] Specifically, pick up the winding rod 5 and insert the positioning end 51 into the insertion hole 171. At this time, the moving column 17 is pushed backward by the winding rod 5. The moving column 17 moves backward, and the spring 18 generates elastic potential energy, which rotates the winding rod 5 so that the locking end 53 corresponds to the slot on the output shaft 41. Then the winding rod 5 moves in the direction of the output shaft 41, so that the spring 18 releases elastic potential energy and the moving column 17 returns to its original position. Several dressing rolls 13 are installed on the winding frame 14. One dressing roll 13 is selected and its connector is passed around the top of the placement column 3, then around the top of the first guide roller 8, then through the guide column 10 and the second guide roller 9, and located between the two limiting blocks 11. The connector is placed on the mounting part 52. Another dressing roll 13 is selected and its connector is passed through the bottom of the placement column 3, then around the top of the first guide roller 8, then through the guide column 10 and the second guide roller 9, also located between the two limiting blocks 11. The connector is placed on the mounting part 52. The dressing roll 13 hangs on the table of the workbench 1 and is close to the column 2. The limiting block 11 moves on the guide rod 12. The protrusion 15 elastically extends and retracts up and down after being affected by the protrusion 121. When both limiting blocks 11 come into contact with the corresponding dressing roll 13, the distance between the two limiting blocks 11 is consistent with the width of the dressing roll 13. The protrusion 15 is then stuck between the two protrusions 121 to limit its movement. Start the motor, and the output shaft 41 begins to rotate. Through the cooperation of the slot and the locking end 53, the winding rod 5 begins to rotate. Then, the joints of the two dressing rolls 13 on the mounting part 52 begin to wind up. When the dressing roll 13 is wound up to a certain length, the motor is stopped and the dressing roll 13 is cut. Then, the winding rod 5 is removed from the equipment, and the cut dressing roll 13 is removed. Then, the dressing roll 13 is wound up and cut again in the above manner.

[0030] In summary, this device, by setting several limiting blocks 11 on the guide rod 12 and adjusting the spacing between two adjacent limiting blocks 11 to match the width of the dressing roll 13, can restrict the tape pulled out from the dressing roll 13 between the two limiting blocks 11, thereby improving the efficiency of replacement. At the same time, it avoids the problem of misalignment of the winding caused by component disassembly and assembly errors, resulting in problems such as dressing edge wrinkles and loose winding, which affect the subsequent storage and use of the dressing. By providing a protrusion 121 at the bottom of the guide rod 12, which matches the protrusion 15 in the limiting block 11, the limiting block 11 can be limited between the two protrusions 121. At the same time, under the action of the spring piece 16, the protrusion 15 can elastically extend and retract, making the limiting block 11 more flexible when adjusting its position. By designing the mounting part 52 of the winding rod 5 as a polygon, the friction of the dressing roll 13 during its winding can be increased, preventing the winding rod 5 from spinning freely when it rotates.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
