Technical Field

[0001] This utility model relates to the field of foam product processing, specifically a screw-lock type blade clamp mounting structure for a vibrating knife. Background Technology

[0002] In the processing of foamed products, the rotary clamping structure of the vibrating knife is well adapted to the cutting needs of foamed materials (such as foam, sponge, EVA, etc.) due to its characteristics of quick loading and unloading and stable clamping.

[0003] The screw-lock type blade clamping structure for vibrating knives is a device for fixing and installing vibrating knife blades. It achieves quick installation and removal of the blades through a screw-lock mechanism. During use, it is usually tightened and loosened using an Allen wrench. However, there is no device to limit the hexagonal rotating block. Under the vibration cutting of the vibrating knife, the clamping of the blade is prone to loosening. Based on this, this utility model proposes a screw-lock type blade clamping structure for vibrating knives. Utility Model Content

[0004] The purpose of this utility model is to provide a screw-lock type blade clamp mounting structure for a vibrating knife in order to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screw-lock type blade clamping structure for a vibrating knife, including a blade cover and a blade clamped on the outside of the top of the blade cover and extending into the inside of the blade cover, and also including a limiting mechanism disposed on the blade cover for clamping the blade; The limiting mechanism includes a transmission unit and a limiting unit; The transmission unit is used to limit the connection between the knife cover and the blade; The limiting unit is used to limit the movement of the transmission unit.

The hexagonal rotating block is used to drive the arc-shaped gear fixed at the end to rotate synchronously. The arc-shaped gear is fixed at the end of the hexagonal rotating block, and the outer wall tooth block of the arc-shaped gear is in conjugate contact with the outer wall tooth block of the conjugate gear. The tooth tip cone and tooth root cone of the arc-shaped gear share the same tip with the corresponding cone of the conjugate gear tooth block. The conjugate gear is rotatably connected to the inner cavity of the cutter cover. The conjugate gear is used to drive the positioning block fixed at the top to rotate synchronously circumferentially.

[0007] As a further improvement of this utility model: the limiting unit includes a movable block, a limiting block, and a spring; The movable block, with its bottom outer wall inclined, is vertically slidably installed on the inner wall of the hexagonal rotating block, and the bottom of the movable block extends to the inner side of the hexagonal rotating block. The limiting block is vertically slidably installed inside the blade cover. The limiting block is used to insert into the inner wall of the hexagonal rotating block under the squeezing force of the spring after being aligned with the top of the movable block. The two ends of the spring are respectively connected to the inner wall of the blade cover and the top of the limiting block. The spring is used to always provide squeezing force to the limiting block.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-3 In this embodiment of the utility model, a screw-on blade clamping structure for a vibrating knife includes a blade cover 1 and a blade 2 clamped on the outside of the top of the blade cover 1 and extending into the inside of the blade cover 1. It also includes a limiting mechanism 3 disposed on the blade cover 1 for clamping the blade 2. The limiting mechanism 3 includes a transmission unit and a limiting unit; The transmission unit is used to limit the docking of the cutter cover 1 and the blade 2; The limiting unit is used to limit the movement of the transmission unit; The transmission unit includes a hexagonal rotating block 301, an arc gear 302, a conjugate gear 303, and a positioning block 304; The hexagonal rotating block 301 is rotatably mounted on the outer periphery of the cutter cover 1 and extends into the inner cavity of the cutter cover 1. The hexagonal rotating block 301 is used to drive the arc gear 302 fixed at the end to rotate synchronously. The arc gear 302 is fixed at the end of the hexagonal rotating block 301, and the outer wall tooth block of the arc gear 302 is in conjugate contact with the outer wall tooth block of the conjugate gear 303. The tooth tip cone and tooth root cone of the arc gear 302 share the same tip with the corresponding cone of the tooth block of the conjugate gear 303. The conjugate gear 303 is rotatably connected to the inner cavity of the cutter cover 1. The conjugate gear 303 is used to drive the positioning block 304 fixed at the top to rotate synchronously in the circumferential direction. The limiting unit includes a movable block 305, a limiting block 306, and a spring 307; The movable block 305, with its bottom outer wall inclined, is vertically slidably installed on the inner wall of the hexagonal rotating block 301, and the bottom of the movable block 305 extends to the inner side of the hexagonal rotating block 301. The limiting block 306 is vertically slidably installed inside the blade cover 1. The limiting block 306 is used to be inserted into the inner wall of the hexagonal rotating block 301 under the squeezing force of the spring 307 after being aligned with the top of the movable block 305. The two ends of the spring 307 are respectively connected to the inner wall of the blade cover 1 and the top of the limiting block 306. The spring 307 is used to always provide the limiting block 306 with squeezing force.

[0015] In this embodiment: By inserting the blade 2 into the slot at the top of the blade cover 1, the bottom of the blade 2 contacts the protruding cylinder at the top of the conjugate gear 303. Then, a hexagonal wrench is inserted into the inner cavity of the hexagonal rotating block 301. The hexagonal wrench contacts the inclined bottom surface of the movable block 305 inside the hexagonal rotating block 301, causing the movable block 305 to move upward under force. The upwardly moving movable block 305 will exert an upward squeezing force on the limiting block 306, causing the limiting block 306 to move out from the inner wall of the hexagonal rotating block 301 and become flush with the outer wall of the hexagonal rotating block 301, thereby releasing the rotation limitation on the hexagonal rotating block 301. Then, by rotating the hexagonal rotating block 301, the arc gear 302 is driven to rotate, causing the outer wall of the arc gear 302 to conjugately contact the conjugate gear 303 and rotate synchronously under force. At the same time, the movable block 305 rotates with the rotation of the hexagonal rotating block 301, and the outer wall at the top of the movable block 305 contacts the inner wall of the rotating slot of the blade cover 1 as it rotates. When the blade is removed, the protruding cylinder at the top of the rotating conjugate gear 303 synchronously drives the side-fixed positioning block 304 to move circumferentially, so that the inclined part at the bottom of the upper horizontal rod of the positioning block 304 makes staggered contact with the side groove of the blade 2, limiting the movement of the blade 2 and completing the installation of the blade 2. At this time, the hexagonal rotating block 301 rotates 5 times, which drives the conjugate gear 303 to rotate half a turn, so that the positioning block 304 rotates 180° synchronously and contacts the inner wall of the blade cover 1. At the same time, the groove opened on the outer wall of the hexagonal rotating block 301 is aligned with the limiting block 306 again. When the hexagonal wrench is pulled out, the limiting block 306 is locked into the inner wall of the hexagonal rotating block 301 again under the action of the spring 307, limiting the rotation of the hexagonal rotating block 301, achieving the purpose of self-locking and automatic release of the limiting of the rotation of the hexagonal rotating block 301. It should be noted that the inner wall of the blade cover 1 is formed with a rotating groove for the positioning block 304 to rotate 180°.

[0016] Please refer to this carefully. Figures 1-3 The positioning block 304 has a "C" shaped structure. The inside of the knife cover 1 is formed with a rotating groove for the hexagonal rotating block 301 to rotate. The rotating groove matches the outer wall of the hexagonal rotating block 301. The bottom of the upper horizontal rod of the positioning block 304 is in an inclined trapezoidal state.

[0017] In this embodiment: This structure allows the positioning block 304 to contact the side groove of the blade 2 under the action of the upper transverse rod of the positioning block 304. The blade 2 is gradually squeezed and limited by the bottom of the inclined upper transverse rod, thus limiting the movement of the blade 2.

[0018] Please refer to this carefully. Figures 1-3 The top of the blade cover 1 is formed with a vertical groove for inserting the blade 2, and the bottom side of the blade 2 is formed with a groove for inserting the upper horizontal rod of the positioning block 304.

[0019] In this embodiment, this structure provides space for the docking of the blade 2 and the blade cover 1.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
