Description

Technical Field

[0001] This utility model belongs to the field of fabric cutting machine technology, and specifically relates to a fabric cutting machine support. Background Technology

[0002] The handheld fabric cutter includes a handheld part with an internal drive unit and a head end connected to one end of the handheld part. This head end is the so-called fabric cutter support, which is used to mount the cutter disc with the mounting plate and to house the transmission component connected to the drive unit. The drive unit is a commercially available electric motor or pneumatic motor. Through the connection between the handheld part and the fabric cutter support, a key connection is achieved between the drive unit and the transmission component. Thus, through the cooperation of the drive unit and the transmission component, the cutter disc mounted on the fabric cutter support is driven to rotate, thereby cutting the fabric.

[0003] Specifically, a circular cutter with an easily detachable worm gear, as described in announcement number CN101724992A, includes a motor, a motor end cover, a worm gear reducer, and a blade. The worm gear reducer is housed within the motor end cover, and the cavity within the motor end cover containing the worm gear is called the worm gear chamber. The worm is connected to the output end of the motor. The worm gear shaft is fixed to the motor end cover with a nut, and the blade is directly fixed to the worm gear. The invention is characterized by: widening the worm gear chamber slightly towards the non-meshing side to form an elongated oval shape; the widened portion should allow the worm gear teeth to disengage from the worm when they hit the wall; enlarging the hole on the motor end cover used to fix the worm gear shaft, so that the worm gear can disengage when the nut fixing the worm gear shaft is removed; and adding a locating ring into the enlarged hole, which allows the worm gear to disengage when removed. The worm gear of this invention is easy to disassemble and replace.

[0004] Because the cutter head installed on the fabric cutting machine support is exposed for a long time, and wear occurs due to its constant cutting, the cutter head needs to be removed and polished frequently. Although removing the cutter head is not difficult, it is still not convenient.

[0005] In view of this, and to address the above problems, this utility model provides a fabric cutting machine support. By setting a movable polishing mechanism on the fabric cutting machine support, the surface of the cutting disc can be polished without disassembling the cutting disc. Utility Model Content

[0028] 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.

[0029] This utility model relates to a support for a fabric cutting machine, such as... Figures 1-5 As shown, it includes: a fabric cutting machine support 1 connected to a handle portion with an internal drive member 16 for mounting the cutter disc 12, and a transmission mechanism disposed inside the fabric cutting machine support 1 and connected to the drive member 16 to drive the cutter disc 12 to rotate. A grinding mechanism 6 is mounted on the fabric cutting machine support 1. The grinding mechanism 6 can be driven by external force to fit against the cutter disc 12 to grind the cutter disc 12.

[0030] Among them, such as Figure 6 As shown. The grinding mechanism 6 includes a bracket 61 for connecting to the fabric cutter support 1, a movable rod 62 that runs through the bracket 61, a grinding wheel 63 and a positioning bolt 64 that are respectively connected to both ends of the movable rod 62, and a spring 65 that is sleeved around the movable rod 62 and located between the positioning bolt 64 and the bracket 61. The grinding wheel 63 is positioned relative to the cutting side of the cutter head 12, and when the spring 65 is in its natural state, the grinding wheel 63 is away from the cutter head 12.

[0031] Combination Figure 7 As shown, when the positioning bolt 64 is pressed, the positioning bolt 64 moves along its axis, driving the grinding wheel 63 at its end to move, gradually approaching and eventually fitting against the cutting side of the cutter head 12. At this time, the spring 65 is in a compressed state and stores elastic potential energy. By controlling the operation of the drive component 16, the transmission mechanism drives the cutter head 12 to rotate, thereby causing relative rotation between the cutter head 12 and the grinding wheel 63, which facilitates the grinding of the cutting side of the cutter head 12. After grinding is completed, the positioning bolt 64 is released, and the spring 65 releases its elastic potential energy, causing the grinding wheel 63 to return to its original position and move away from the cutter head 12, so that it will not obstruct the normal operation of the cutter head 12.

[0032] Furthermore, such as Figures 1-3 , Figure 8As shown, in order to make the bracket 61 more secure and prevent the relative force generated when grinding the cutter head 12 from causing the bracket 61 to loosen, an installation notch 5 can be deepened at the locking and positioning hole 101 for locking with the handle on the surface of the fabric cutter support 1. The installation notch 5 matches the end of the bracket 61 away from the grinding wheel 63, so that the end of the bracket 61 can be embedded in the installation notch 5. The movement of the end of the bracket 61 is restricted by the inner side wall of the installation notch 5, which can effectively resist the movement of the bracket 61 caused by the relative force, so that the bracket 61 is more securely fixed.

[0033] It should be noted that at least two sets of positioning holes 101 are generally symmetrically opened to ensure the firmness of the connection between the fabric cutter support 1 and the handle. At the same time, the mounting notch 5 should be deepened and opened at the positioning hole 101 near the surface where the cutter head 12 is located, so that the mounting notch 5 is closer to the surface where the cutter head 12 is located, thereby reducing the length of the bracket 61 and the shape distortion caused by the setting of the grinding wheel 63 relative to the cutting side of the cutter head 12.

[0034] like Figures 1-5 As shown, the fabric cutting machine support 1 has an internal slot for housing the transmission mechanism. The slot includes a first groove 2 on the surface of the support 1 and a second groove 3 connected to the first groove 2. The other end of the first groove 2, away from the second groove 3, connects to the connection surface between the fabric cutting machine support 1 and the handle, allowing the movable end of the drive member 16 to extend into the first groove 2 and connect with the transmission mechanism. The transmission mechanism includes a worm gear 10 located in the first groove 2 and keyed to the movable end of the drive member 16, and a worm wheel 9 located in the second groove 3 and meshing with the worm gear 10. The end of the worm gear 10 has a keyway 11, such as... Figure 8 As shown, when the fabric cutter support 1 is connected to the handle, the output end of the drive component 16 in the handle can be inserted into the keyway 11 to achieve a key connection with the worm gear 10.

[0035] In this embodiment, to accommodate the placement of the worm gear 10 and the worm wheel 9, the first groove 2 is cylindrical to facilitate the insertion of the worm gear 10, while the second groove 3 is circular to accommodate the worm wheel 9. The center of the second groove 3 is deepened to provide a bolt hole that passes through the fabric cutting machine support 1. This bolt hole is used to position the mounting plate 8 of the cutter disc 12 to facilitate the subsequent installation of the cutter disc 12.

[0036] Specifically, such as Figure 7As shown, a bearing 7 coaxial with the bolt hole is provided in the second groove 3. The bearing 7 has an inner ring and an outer ring that rotate relative to each other. The diameter of the inner ring is larger than that of the bolt hole and is fixedly connected to the bottom wall of the second groove 3. The center of the mounting plate 8 is provided with a through hole that matches the outer ring of the bearing 7. On both sides of the mounting plate 8, a protruding cylinder for fixing the worm gear 9 and a limiting cylinder 81 for fixing the cutter head 12 are formed along its axis. The mounting plate 8 can be axially restricted in the second groove 3 by a fastening bolt 13 whose end passes through the limiting cylinder 81, the inner ring of the bearing 7 and the bolt hole. The end of the fastening bolt 13 passes through the bolt hole and is connected and locked with the nut 14. The cutter head 12 is locked to the mounting plate 8 by a cutter head nut 15 threaded to the periphery of the limiting cylinder 81. When the driving member 16 drives the worm gear 10 to rotate, the mounting plate 8 can be driven to rotate in the second groove 3 through the outer ring of the bearing 7 with the cooperation of the worm gear 9, so as to drive the cutter head 12 to rotate and form a cutting action.

[0037] To provide a certain degree of enclosure for the periphery of the cutter head 12 and prevent safety hazards, a cutter groove 4, adapted to the size of the cutter head 12, is coaxially deepened on the surface of the fabric cutting machine support 1 and located at the second groove 3. Figure 2 As shown, the cutter groove 4 is arc-shaped, and its inner wall can surround the upper half of the cutter head 12 to improve the safety of use.

[0038] like Figure 8 This shows a schematic diagram of the combination between the fabric cutting machine support 1 and the handle.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
