Description

Technical Field

[0001] The utility model relates to the technical field of shearing machines, in particular to a medical non-woven fabric shearing machine capable of adjusting the shearing size. Background Art

[0002] According to the search of China Invention Announcement No.: CN217298418U, a medical non-woven fabric shearing machine capable of adjusting the shearing size is disclosed, including a connecting frame, a fixing pin is pierced on the upper surface of the connecting frame, a connecting shaft is rotatably connected to the front of the connecting frame, a fixing frame is installed on the front of the connecting frame, an auxiliary plate is installed on the front of the connecting frame, and a moving bar is arranged inside the fixing frame. The medical non-woven fabric shearing machine capable of adjusting the shearing size can accurately adjust the position of the cutter according to the scale on the scale plate by manipulating the moving bar to move right along the fixing frame, and then the contact plate moves downward to contact the non-woven fabric for fixing, thereby making it easier for the operator to adjust the position of the components in the device according to the needs, and can prevent the deviation of the shearing size caused by the relatively fixed positions between the components, and further improve the precision of the components in the device in shearing the non-woven fabric.

[0003] However, when implementing the above technical scheme, there are the following problems: the above scheme can realize the rapid adjustment of any scale when cutting non-woven fabrics, but it is difficult to ensure that the position of the knife structure used for cutting in the above scheme will not change under the action of external force after the position is adjusted. In the scheme, the change of the position of the knife structure is achieved by sliding the block inside the groove. After the position is determined, the structure is not directly restricted from sliding again. If it is affected by external force or the friction is reduced for a long time, the shearing of the non-woven fabric during transmission will cause the position of the knife structure to change, so that there is an error between the length after cutting and the expected length. For this reason, the utility model provides a medical non-woven fabric shearing machine that can adjust the shearing size. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a medical non-woven fabric shearing machine capable of adjusting the cutting size, which solves the problem that the knife structure of the medical non-woven fabric shearing machine is difficult to quickly limit and move again after adjusting the position, and is prone to move under the action of the moving non-woven fabric after long-term use, resulting in errors in the length of the non-woven fabric after cutting.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a medical non-woven fabric shearing machine capable of adjusting the shearing size, comprising a shearing frame, the surface of which is provided with an adjustment mechanism to adjust the position of the shearing structure, and the adjustment mechanism includes:

[0007] An operating rod is arranged on the inner thread of the limit block, and a limit assembly is arranged between the operating rod and the shear frame to realize rotation restriction.

[0008] Preferably, the sliding assembly comprises a sliding shaft fixed on the surfaces of the limiting block and the fixed block, and a sliding groove is provided inside the shearing frame.

[0009] Preferably, the disassembly assembly includes a fixed rod and a push rod that slide inside the shear block, and a moving assembly is provided between the fixed rod, the push rod and the shear block to achieve trajectory restriction.

[0010] Preferably, the moving assembly comprises a moving groove opened inside the shear block, and a moving spring is fixed between the moving groove, the push rod and the fixing rod.

[0012] Preferably, the driving assembly includes a driving shaft fixed inside the limiting gear, and a driving groove is formed on the surface of the operating rod.

[0013] Beneficial Effects

[0014] The utility model provides a medical non-woven fabric shearing machine capable of adjusting the shearing size. Compared with the prior art, it has the following beneficial effects:

[0015] (1) The medical non-woven fabric shearing machine capable of adjusting the shearing size has a slidable fixed block disposed inside the shearing frame. The fixed block can slide inside the shearing frame to change the position of the internal shearing block inside the shearing frame, thereby changing the position of the shearing knife relative to the non-woven fabric on the surface of the sliding structure. Furthermore, the size of the non-woven fabric after shearing can be changed in many aspects by changing the extension time of the electric telescopic rod and the position of the shearing knife. The shearing block and the shearing knife can be disassembled, so that the knife used can be changed when shearing non-woven fabrics of different sizes, thereby ensuring that the structure on the surface of the shearing frame will not be damaged by the shearing knife, thereby ensuring the service life of the entire device.

[0016] (2) The medical non-woven fabric shearing machine capable of adjusting the shearing size has a sliding fixing rod which can be controlled by a push rod disposed inside the shearing block. The positions of the shearing block and the fixing block can be limited by the contact between the triangle of the fixing rod and the triangular groove surface of different depths on the surface of the fixing block. A movable spring is fixed on the opposite side of the sliding track of the pushing rod and the fixing rod to the shearing block, so that the position can be quickly restored when no force is applied, and the precise locking of the structure can be quickly achieved, ensuring that the shearing effect will not be affected during use.

A limit assembly 5 is provided between the operating rod 22 and the shear frame 1 to achieve rotation restriction.

[0027] A slidable fixed block 211 is arranged inside the shear frame 1. The fixed block 211 can change the position of the internal shear block 213 inside the shear frame 1 by sliding inside the shear frame 1, and can change the position of the shear knife 214 relative to the non-woven fabric on the surface of the sliding structure. Furthermore, the size of the non-woven fabric after shearing can be changed in many aspects by changing the extension and retraction time of the electric telescopic rod and the position of the shear knife 214.

[0028] Embodiment 2

[0029] The main difference from the first embodiment is:

[0030] A medical nonwoven shearing machine capable of adjusting the shearing size, wherein the sliding assembly 3 includes a sliding shaft 31 fixed on the surfaces of a limit block 212 and a fixed block 211, a sliding groove 32 is provided inside the shearing frame 1, and the surface of the sliding shaft 31 is slidably connected with the inner surface of the sliding groove 32, and the disassembly assembly 4 includes a fixed rod 41 and a pressing rod 42 that slide inside the shearing block 213, and the surface of the pressing rod 42 has a triangular shape fixed on different faces, and the surface of the fixed rod 41 has a corresponding triangular shape, corresponding to The triangular surface of the vertical surface is fixed, the surface of the fixed block 211 is provided with triangular grooves of different depths, the fixed rod 41 is triangular, and a moving component 43 is provided between the fixed rod 41 and the push rod 42 and the shear block 213 to realize trajectory restriction, and the moving component 43 includes a moving groove 431 provided inside the shear block 213, and a moving spring 432 is fixed between the moving groove 431 and the push rod 42 and the fixed rod 41, and the surfaces of the push rod 42 and the fixed rod 41 are slidably connected with the inner surface of the moving groove 431 The limit assembly 5 includes a limit gear 51 that slides with the surface of the operating rod 22, a limit groove 52 is provided on the surface of the shearing frame 1, and a tooth-shaped protrusion is provided inside the limit groove 52. A driving assembly 53 is provided between the limit gear 51 and the operating rod 22 to achieve position change, and the driving assembly 53 includes a driving shaft 531 fixed inside the limit gear 51, and a driving groove 532 is provided on the surface of the operating rod 22. The surface of the driving shaft 531 is slidably connected with the inner surface of the driving groove 532. A sliding fixing rod 41 that can be controlled by a pressing rod 42 is provided inside the shear block 213. The contact between the triangular surface of the fixing rod 41 and the triangular groove surface of different depths on the surface of the fixing block 211 can limit the position of the shear block 213 and the fixing block 211. A moving spring 432 is fixed on the opposite side of the sliding track of the pressing rod 42 and the fixing rod 41 to the shear block 213, so that the position can be quickly restored when no force is applied, and the precise card joint of the structure can be quickly realized to ensure that the shearing effect will not be affected during use.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] When working, when replacing the shear block 213 and the shear knife 214, first press the pressing rod 42. The sliding of the pressing rod 42 through the triangular surface will drive the fixing rod 41 to move upward or downward, thereby shortening the distance between the fixing rods 41 and causing the surface of the fixing rod 41 to disengage from the surface groove of the fixing block 211. At this time, the shear block 213 can be pulled to achieve the disengagement of the shear block 213 and the fixing block 211. When installing, the shear block 213 is placed in the corresponding position and then the pressing rod 42 is released. When moving the fixing block 211, it is first necessary to pull the limiting gear 51 upward to cause the surface of the limiting gear 51 to disengage from the inner surface of the limiting groove 52, and rotate the operating rod 22. The rotation of the operating rod 22 causes the surface of the limiting block 212 to disengage from the surface of the fixing block 211. At this time, the fixing block 211 can be pulled to change the position of the fixing block 211. After the position is determined, the operating rod 22 is reversed, and the position of the limiting gear 51 is restored to achieve the adjustment of the shear position.
