Description

Technical Field

[0001] This utility model relates to the field of die-cutting device technology, specifically to a cutting machine. Background Technology

[0002] In the die-cutting process of rubber strips, different cutting requirements necessitate the use of different sizes or shapes of cutting tools. Common cutting machines require a feeding mechanism at the inlet and a detection mechanism at the outlet. Changing the cutting tool necessitates disconnecting the feeding mechanism from the cutting machine and relocating the feeding mechanism to provide space for the change. However, this method of changing cutting tools undoubtedly increases the workload for operators and is quite inconvenient.

[0003] Therefore, there is an urgent need for a cutting machine to solve the common problem of inconvenient tool replacement in cutting machines. Utility Model Content

The drive cylinder drives the tool mounting housing to move up and down. The tool mounting housing has a drive cavity and a tool mounting cavity located below the drive cavity. The telescopic drive structure is installed in the drive cavity. A limiting post that can move up and down is installed through the wall between the drive cavity and the tool mounting cavity. The telescopic drive structure connects to and drives the limiting post to extend and retract up and down. The right side of the tool mounting cavity is open. A corresponding tool feeding cavity is opened on the right side of the cutting machine housing. A mounting hole is opened at the bottom of the tool mounting cavity. The tool can be mounted in the tool mounting cavity with the blade extending downward from the mounting hole. The limiting post can be moved down to limit the tool at the bottom of the tool mounting cavity.

[0007] To optimize the above technical solution, the specific measures also include:

[0008] Furthermore, the telescopic drive structure includes a rotating rod and a drive structure. The drive structure includes a driving bevel gear, a first driven bevel gear, a second driven bevel gear, and a third driven bevel gear. The rotating rod is rotatably arranged in the drive cavity along the left-right direction via a first limiting rod. One end of the rotating rod rotatably protrudes from the right side of the drive cavity. The driving bevel gear is fixedly sleeved on the rotating rod. The first driven bevel gear meshes with the driving bevel gear. The side of the first driven bevel gear away from the driving bevel gear is symmetrically fixedly connected to the second driven bevel gear via a connecting rod. The connecting rod is rotatably arranged in the drive cavity via a second limiting rod. The second driven bevel gear meshes with the third driven bevel gear. The third driven bevel gear is rotatably arranged laterally in the drive cavity via a rotating seat and is vertically offset from the driving bevel gear. The limiting post is vertically inserted into the axis of the third driven bevel gear, which can only move up and down. The outer wall of the limiting post located below the third driven bevel gear has an external thread, and is screwed into the wall surface through the external thread.

[0009] Furthermore, the side wall of the limiting post is provided with a vertical sliding groove, and the shaft of the third driven bevel gear is provided with a protrusion that is engaged in the sliding groove. The limiting post is slidably disposed at the shaft of the third driven bevel gear, and the protrusion is slidably engaged in the sliding groove.

[0010] Furthermore, a through sliding hole is provided on the right side wall of the cutting machine housing corresponding to the rotating rod. A drive rod is provided through the sliding hole and can slide left and right. The end of the drive rod near the rotating rod is toothed, and the end of the rotating rod near the drive rod is toothed and can mesh with the drive rod.

[0011] Furthermore, a handle is provided at the end of the drive rod located away from the rotating rod and on the right side of the cutting machine housing.

[0012] Furthermore, the side cross-section of the tool mounting cavity is T-shaped, the mounting hole is located in the middle of the bottom, the left and right sides of the tool are mounted on the upper bottom of the tool mounting cavity located on the left and right sides of the mounting hole, and the cutting edge of the tool extends downward from the mounting hole.

[0013] Furthermore, the drive structure is provided in two sets, which are respectively located on the left and right sides and are connected to the two limiting posts through the third driven bevel gear. The two limiting posts are respectively used to move down to limit the left and right sides of the tool to the bottom of the tool mounting cavity.

[0014] Furthermore, a positioning post is vertically installed at the bottom of the tool mounting housing, and a positioning groove is correspondingly opened at the bottom of the cavity of the cutting machine housing for the positioning post to be inserted.

[0016] Furthermore, two positioning posts are symmetrically arranged on the bottom of the tool mounting housing, and two positioning grooves are correspondingly opened at the bottom of the cavity of the cutting machine housing.

[0017] The beneficial effects of this utility model are:

[0018] This invention, through the design of a tool mounting cavity inside the tool mounting housing and a tool feeding cavity on the right side of the cutting machine housing, allows the tool to be inserted from the side of the device through the tool feeding cavity and into the tool mounting cavity through the opening on the right side of the tool mounting cavity during use. Combined with the drive cavity, telescopic drive structure, and limiting post inside the tool mounting housing, the telescopic drive structure drives the limiting post to move up and down. When a tool needs to be installed, the limiting post moves upward to provide installation space; after the tool is placed, the limiting post moves downward to limit the tool at the bottom of the tool mounting cavity, thus facilitating convenient tool replacement or installation. During use, the tool mounting housing, carrying the tool inside, moves up and down via a drive cylinder to perform cutting operations.

[0019] In use, this invention allows the rotating rod to drive the active bevel gear to rotate, which in turn drives the transmission structure consisting of the first driven bevel gear, the second driven bevel gear, and the connecting rod. This transmission drives the third driven bevel gear to rotate, which in turn drives the limiting post connected to it to rotate. The limiting post, under the constraint of being threaded onto the wall surface, moves vertically up and down during rotation, thereby separating from the tool or clamping the tool. Furthermore, multiple sets of this drive structure can be configured as needed and conveniently and synchronously driven by a single rotating rod.

[0020] In use, this utility model allows for convenient and synchronous rotation of the rotating rod by moving the drive rod until it engages with the rotating rod. After adjustment, the drive rod can be moved to separate from the rotating rod, thus preventing interference from the drive rod when the tool mounting housing is performing cutting operations.

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] As attached Figure 1 As shown, a cutting machine according to an embodiment of the present invention includes a cutting machine housing 1, a drive cylinder 2, a tool mounting housing 3, a telescopic drive structure 5, and a limiting post 7. The cutting machine housing 1 has a through-cavity at its center. The tool mounting housing 3 is mounted on the top of the cavity via the drive cylinder 2. The drive cylinder 2 drives the tool mounting housing 3 to move up and down. The tool mounting housing 3 has a drive cavity 31 and a tool mounting cavity 32 located below the drive cavity 31. The telescopic drive structure 5 is installed inside the drive cavity 31. A vertically movable limiting post 7 is installed through the wall between the moving cavity 31 and the tool mounting cavity 32. The telescopic drive structure 5 is used to connect and drive the limiting post 7 to extend and retract vertically. The right side of the tool mounting cavity 32 is open, and a corresponding tool feeding cavity 11 is provided on the right side of the cutting machine housing 1. A mounting hole is provided in the middle of the bottom of the tool mounting cavity 32. The tool 8 can be mounted in the tool mounting cavity 32 and the cutting edge of the tool 8 can extend downward from the mounting hole. The limiting post 7 can be moved down to limit the tool 8 to the bottom of the tool mounting cavity 32.

[0028] This invention, through the tool mounting cavity 32 inside the tool mounting housing 3 and the tool feeding cavity 11 on the right side of the cutting machine housing 1, allows the tool 8 to be passed through the tool feeding cavity 11 from the side of the device and inserted into the tool mounting cavity 32 through the opening on the right side of the tool mounting cavity 32 during use. Combined with the drive cavity 31, telescopic drive structure 5, and limiting post 7 inside the tool mounting housing 3, the limiting post 7 can be moved up and down by the telescopic drive structure 5. When the tool 8 needs to be installed, the limiting post 7 moves upward to provide installation space. After the tool 8 is placed, the limiting post 7 moves downward to limit the tool 8 to the bottom of the tool mounting cavity 32, thus facilitating the convenient replacement or installation of the tool 8. During use, the tool mounting housing 3, carrying the tool 8 inside, moves up and down via the drive cylinder 2 to perform cutting operations.

[0029] In one specific embodiment based on the above, the telescopic drive structure 5 can be an electric telescopic rod, and the moving end of the electric telescopic rod is connected to the limiting post 7 to realize the movement drive of the limiting post 7.

[0030] As attached Figure 2 and attached Figure 3 As shown, in another specific embodiment based on the above, the telescopic drive structure 5 includes a rotating rod 53 and a drive structure. The drive structure includes a driving bevel gear 52, a first driven bevel gear 54, a second driven bevel gear 56, and a third driven bevel gear 57. The rotating rod 53 is rotatably disposed in the drive cavity 31 along the left-right direction via a first limiting rod 51. One end of the rotating rod 53 rotatably protrudes from the right side of the drive cavity 31. The driving bevel gear 52 is fixedly sleeved on the rotating rod 53. The first driven bevel gear 54 meshes with the driving bevel gear 52, and the first driven bevel gear 54 is away from the driving bevel gear 57. A second driven bevel gear 56 is symmetrically fixed to one side of 2 via a connecting rod. The connecting rod is rotatably mounted in the drive cavity 31 via a second limiting rod 55. The second driven bevel gear 56 meshes with a third driven bevel gear 57, and the third driven bevel gear 57 is rotatably mounted laterally in the drive cavity 31 via a rotating seat 58, and is vertically offset from the driving bevel gear 52. A limiting post 7 is vertically inserted into the axis of the third driven bevel gear 57, which can only move up and down. The outer wall of the limiting post 7 located below the third driven bevel gear 57 is provided with an external thread, and is screwed into the wall surface through the external thread.

[0031] Therefore, during use, the rotating rod 53 can be rotated to drive the active bevel gear 52 to rotate, and the transmission structure composed of the first driven bevel gear 54, the second driven bevel gear 56 and the connecting rod will drive the third driven bevel gear 57 to rotate. The third driven bevel gear 57 will then drive the limiting post 7 connected to it to rotate. Under the restriction of being threaded to the wall surface, the limiting post 7 will move up and down vertically during rotation, thereby separating from the tool 8 or pressing the tool 8.

[0032] In this solution, the aforementioned drive structure can be set in multiple groups as needed, and can be conveniently and synchronously driven by a single rotating rod 53.

[0033] The limiting post 7 has a vertical groove on its side wall, and a protrusion at the shaft of the third driven bevel gear 57 engages in the groove. The limiting post 7 is slidably positioned at the shaft of the third driven bevel gear 57, with the protrusion slidably engaged in the groove. This design limits both the vertical movement of the limiting post 7 during rotation and its range of motion. In this solution, the external thread on the limiting post 7 is located below the groove to prevent it from interfering with the sliding connection with the third driven bevel gear 57.

[0034] The right side wall of the cutting machine housing 1 has a through-hole corresponding to the rotating rod 53. A drive rod 6 is inserted through the hole and can slide left and right. The end of the drive rod 6 near the rotating rod 53 is toothed, and the end of the rotating rod 53 near the drive rod 6 is toothed and can mesh with the drive rod 6. In this way, during use, the rotation of the rotating rod 53 can be conveniently and synchronously driven by moving the drive rod 6 until it engages with the rotating rod 53. After adjustment, the drive rod 6 can be moved to disengage from the rotating rod 53, thereby avoiding interference of the drive rod 6 when the tool mounting housing 3 is performing cutting operations.

[0035] The drive rod 6 has a handle at its end, which is away from the rotating rod 53 and located on the right side of the cutting machine housing 1. This facilitates the rotation of the drive rod 6.

[0036] As attached Figure 4 As shown, in another specific embodiment based on the above, the side cross-section of the tool mounting cavity 32 is T-shaped, with the mounting hole located in the middle of the bottom. The left and right sides of the tool 8 are mounted on the upper bottom of the tool mounting cavity 32 located on the left and right sides of the mounting hole, and the cutting edge of the tool 8 extends downward from the mounting hole. This facilitates the positioning and installation of the tool 8.

[0037] The aforementioned drive structure is provided in two sets, which are respectively located on the left and right sides and connected to two limiting posts 7 via the third driven bevel gear 57. The two limiting posts 7 are respectively used to move down to limit the left and right sides of the tool 8 to the bottom of the tool mounting cavity 32.

[0038] In another specific embodiment based on the above, a positioning post 4 is vertically installed at the bottom of the tool mounting housing 3, and a positioning groove 12 is correspondingly opened at the bottom of the cavity of the cutting machine housing 1 for the positioning post 4 to be inserted. This facilitates the guidance and positioning of the tool mounting housing 3 during its movement.

[0039] The lower end of the aforementioned positioning post 4 is tapered. The bottom of the aforementioned tool mounting housing 3 is symmetrically provided with two positioning posts 4, and two corresponding positioning grooves 12 are formed at the bottom of the cavity of the cutting machine housing 1.
