Description

Technical Field

[0001] This utility model relates to the technical field of filter rod forming equipment, specifically to a blade sleeve assembly, a blade box structure, and a composite filter rod forming machine. Background Technology

[0002] The composite filter rod forming machine consists of a combination machine and a forming machine. It initially cuts different types of filter rod strips into filter rods, combines them in sequence, and conveys them to the forming machine to roll them into shape. The combined filter rod strips are then cut into qualified single filter rods, which are finally output through a conveying device.

[0003] In existing composite filter rod forming units, the circular blades are set in the blade box and it is difficult to adjust the spacing of the circular blades. If it is necessary to adjust the cutting length of the filter rod strips, the end cover of the blade box must be removed to expose the blade shaft and the circular blades and make adjustments, which is a very cumbersome operation. Utility Model Content

[0004] The purpose of this utility model is to provide a blade sleeve assembly, a blade box structure, and a composite filter rod forming machine that can adjust the distance between the circular blades without removing the end caps, thereby overcoming the problem of inconvenient adjustment of the distance between existing circular blades.

[0005] The above-mentioned utility model objective is achieved through the following technical solution:

[0006] On the one hand, the present invention provides a blade sheath assembly, including a blade sheath, a blade sheath locking sleeve fixedly provided at one end of the blade sheath, a strip-shaped notch distributed along the axial direction on the side wall of the blade sheath locking sleeve, a pressure block provided at the strip-shaped notch, and the pressure block being fixedly connected to the blade sheath locking sleeve by a locking screw.

[0007] Optionally, it also includes a circular cutter. The cutter sleeve includes a male sleeve and a female sleeve, which are threaded together. A pressure ring is provided at the joint of the male sleeve and the female sleeve, and the circular cutter is clamped between the two pressure rings.

[0008] On the other hand, this utility model provides a knife box structure, including a knife box body. A slot is opened on one side of the knife box body, and a plurality of knife shafts are rotatably arranged in the slot. The outer wall of the knife shaft is provided with grooves distributed along the axial direction. A plurality of the above-mentioned knife sleeve assemblies are movably sleeved on the knife shaft. When the pressing surface of the pressing block abuts against the concave surface of the groove, the knife sleeve locking sleeve is in a locked state.

[0009] Optionally, the knife box body has a through hole corresponding to each of the knife shafts on one side of the slot. The inner diameter of the through hole is larger than the outer diameter of the round knife. An end cap is installed on the knife box body at the through hole, and the end of the knife shaft near the end cap is rotatably connected to the end cap.

[0010] Optionally, a drive motor is fixedly installed on the side of the blade box body away from the through hole, and one end of the blade shaft passes through the blade box body and is connected to the output end of the drive motor.

[0011] On the other hand, this utility model also provides a composite filter rod forming machine, which uses the above-mentioned blade sleeve assembly.

[0012] Compared with the prior art, this utility model provides a blade sleeve assembly, a blade box structure, and a composite filter rod forming machine, which has the following beneficial effects:

[0013] 1. This utility model adds a tool holder locking sleeve and a pressure block to the tool holder and opens a groove on the tool shaft. Therefore, it is not necessary to remove the end cover. The position of the tool holder assembly on the tool shaft can be adjusted by directly loosening the locking screw on the pressure block. Therefore, the adjustment of the circular tool spacing is simple and quick.

[0014] 2. This utility model has a pressure ring on the blade sleeve to clamp the round blade, which can prevent the round blade from deforming under stress and reducing the cutting accuracy during operation. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1-3As shown, this embodiment proposes a tool holder assembly, including a tool holder 1 and a circular cutter 3. The tool holder 1 includes a male sleeve 101 and a female sleeve 102, which are threaded together. A pressure ring 103 is provided at the mating point of the male sleeve 101 and the female sleeve 102, and the circular cutter 3 is sandwiched between the two pressure rings 103. A tool holder locking sleeve 2 is provided at one end of the tool holder 1. In order to shorten the length of the tool holder assembly, it is preferable to fix the tool holder locking sleeve 2 at one end of the male sleeve 101. The side wall of the tool holder locking sleeve 2 has a strip-shaped notch 201 distributed along the axial direction. A pressure block 4 is provided at the strip-shaped notch 201. The two ends of the pressure block 4 are threadedly connected to the side wall of the tool holder locking sleeve 2 by locking screws for fixation.

[0021] On the other hand, this embodiment provides a tool holder structure, including a tool holder body 6. A slot 601 is provided on one side of the tool holder body 6, and a plurality of tool shafts 5 are rotatably disposed within the slot 601. The outer wall of each tool shaft 5 has axially distributed grooves 501. A plurality of the aforementioned tool sleeve assemblies are movably sleeved on the tool shaft 5. When the pressing surface of the pressure block 4 presses against the concave surface of the groove 501, the tool sleeve locking sleeve 2 is locked. It should be noted that the inner hole of the male sleeve 101 in the tool sleeve assembly is a circular hole, and the inner diameter of the male sleeve 101 is equal to the outer diameter of the tool shaft 5, to facilitate the rotation of the male sleeve 101 on the tool shaft 5 and its tightening into the female sleeve 102. The tool sleeve locking sleeve 2, after cooperating with the locking pressure block 4, can remain locked along the axial direction of the tool shaft 5. Therefore, when it is necessary to adjust the spacing of the circular cutter 3, loosen the locking screws at both ends of the pressure block 4 so that the pressure block 4 no longer restricts the circumferential degree of freedom of the cutter sleeve lock 2, and the position of the cutter sleeve lock 2 on the cutter shaft 5 can be adjusted. The adjustment method is simple and quick.

[0022] Based on this embodiment, the blade holder body 6 has through holes 602 corresponding to each blade shaft 5 on one side of the slot 601. The inner diameter of the through hole 602 is larger than the outer diameter of the circular blade 3, and an end cap 7 is installed on the blade holder body 6 at the through hole 602. The end of the blade shaft 5 near the end cap 7 is rotatably connected to the end cap 7. A drive motor 8 is fixedly installed on the side of the blade holder body 6 away from the through hole 602. One end of the blade shaft 5 passes through the blade holder body 6 and is coaxially connected to the output end of the drive motor 8. With this design, the circular blade 3 can be removed from the through hole 602 and replaced when changing it.

[0023] On the other hand, this embodiment also provides a composite filter rod forming machine that uses the aforementioned blade sleeve assembly.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
