When the raw material roll is used up, the user can easily replace the raw material roll to avoid unnecessary trouble to the user.

[0004] When the material roll needs to be replaced, the material cutting device rotates the rotating plate outward, pulls the limit block upward by the handle to make it out of the short slot, and then takes out the old material roll and puts the new material roll into the short slot. The limit block and the rotating plate are two completely separated installation structures. During the installation process, the limit block needs to be carried and placed, and the limit block is prone to collision when moving.

[0005] In order to solve the above problems, the utility model proposes a material cutting device for wound patch production. Utility Model Content

[0024] like Figure 1-Figure 5 As shown, the technical solution adopted by the utility model is as follows: a material-cutting device for wound patch production includes a material-cutting body 1, and two symmetrical vertical plates 8 are fixedly connected to the top of one end of the material-cutting body 1, and grooves 4 are provided on the tops of the two vertical plates 8. A rotating shaft 3 is provided on the two vertical plates 8, and a motor 2 is fixedly provided on one side of one of the vertical plates 8, and one end of the rotating shaft 3 is connected to the output shaft of the motor 2. A limiting block 5 is fixedly connected to one end of the rotating shaft 3 close to the motor 2, and a limiting groove matched with the limiting block 5 is provided at one end of the output shaft of the motor 2, and the limiting block 5 is clamped in the limiting groove. When installing the rotating shaft 3, the limiting block 5 is located in the limiting groove, and the rotating shaft 3 and the output shaft of the motor 2 are connected. When the motor 2 is started to rotate the output shaft, the rotating shaft 3 is driven to rotate together.

[0025] The two grooves 4 are provided with support components for supporting the ends of the rotating shaft 3. The support components include a U-shaped support plate 9, and an arc groove adapted to the ends of the rotating shaft 3 is provided in the middle of the support plate 9. Positioning strips are fixedly connected to both sides of the support plate 9, and two positioning grooves are provided on the inner wall of the groove 4, and the positioning strips are slidably connected to the positioning grooves. A screw rod 10 is fixedly connected to the bottom of the support plate 9.

[0026] The groove 4 is provided with an annular groove, and a semi-annular limiting plate 6 is rotatably arranged inside the annular groove. The inner annular surface of the limiting plate 6 matches with the rotating shaft 3, and the rotating shaft 3 is limited by the inner annular surface of the limiting plate 6. The center of the rotating shaft 3 and the center of the limiting plate 6 are on the same vertical line. A handle 7 is fixedly connected to one side of the end of the limiting plate 6 extending out of the annular groove. An arc-shaped sliding groove 15 is provided on the vertical plate 8, and the handle 7 is slidably arranged in the sliding groove 15.

[0027] A transmission assembly is provided on one side of the limit plate 6, and the transmission assembly drives the screw 10 to move up and down in the groove 4. The transmission assembly includes a worm 13, and the worm 13 is rotatably connected in the groove 4. The bottom surface in the groove 4 is rotatably connected with a worm wheel 11, and the worm wheel 11 is meshed with the middle part of the worm 13, and the screw 10 is threadedly connected in the worm wheel 11. A semi-circular rack 14 is provided on one half of the inner ring surface of the limit plate 6, and a gear 12 is fixedly sleeved at one end of the worm 13, and the gear 12 is meshed with the rack 14. The length of the rack 14 is less than the length of the limit plate 6, and one end of the rack 14 is located at the handle 7.

[0028] Working principle:

[0029] When in use, the raw material roll for producing the wound patch is sleeved on the rotating shaft 3, and then the rotating shaft 3 is moved to the two vertical plates 8 so that both ends of the rotating shaft 3 are located in the supporting plate 9. The limiting groove and the limiting block 5 are both in a vertical state.

[0030] Pull the handle 7 toward the top of the rotating shaft 3 to drive the limit plate 6 to rotate in the annular groove. The rotation of the limit plate 6 drives the gear 12 and the worm 13 to rotate through the rack 14, so that the worm wheel 11 rotates on the screw rod 10. Since the worm wheel 11 is threadedly connected to the screw rod 10, and the support plate 9 is fixed to the top of the screw rod 10, the screw rod 10 moves downward in the worm wheel 11, and the support plate 9 is pulled downward, so that the rotating shaft 3 moves downward, and then the end of the rotating shaft 3 moves into the groove 4.

[0031] When the handle 7 is rotated to the top of the rotating shaft 3, the rotating shaft 3 is connected with the output shaft of the motor 2 as the support plate 9 moves. The limit block 5 on the rotating shaft 3 is just stuck in the limit groove on the output shaft of the motor 2, connecting the rotating shaft 3 and the output shaft of the motor 2, and the installation of the rotating shaft 3 is completed. The rack 14 is just separated from the gear 12, and the limit plate 6 is continued to rotate, the rack 14 leaves the gear 12, the gear 12 will not rotate, and the rotating shaft 3 will no longer move. At the same time, the limit plate 6 limits the rotating shaft 3.

[0032] When the handle 7 moves to the inner wall of the groove 4, the top of the rotating shaft 3 is always in contact with the inner ring surface of the limiting plate 6. At this time, the limiting plate 6 limits the up and down movement of the rotating shaft 3 and positions the limiting plate 6. When the motor 2 is started to rotate the output shaft, the rotating shaft 3 is driven to rotate together to transport the raw material roll on the rotating shaft 3. The speed of the motor 2 should not be too large, so as to facilitate the subsequent cutting of the material and avoid the rotating shaft 3 from being thrown out.

[0033] When the raw material roll is used up, first rotate the limit block 5 to the position at the top of the output shaft of the motor 2. The limit block 5 is in a vertical state. The hand handle 7 rotates the limit plate 6 to one side of the slide groove 15, so that the limit plate 6 slides to the outside of the rotating shaft 3. When the limit plate 6 rotates, the rack 14 will rotate toward the gear 12 along with the limit plate 6. When the handle 7 is rotated to the top of the rotating shaft 3, the rack 14 will mesh with the gear 12, which will drive the gear 12 and the worm 13 to rotate, so that the worm wheel 11 rotates on the screw 10. The screw 10 moves upward in the worm wheel 11, and pushes the support plate 9 upward, so that the rotating shaft 3 moves upward. The limit block 5 leaves the limit groove.

[0034] When the handle 7 is rotated to the bottom end of the slide groove 15 , the end of the rotating shaft 3 is moved out of the groove 4 , and the rotating shaft 3 can be replaced at this time.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
