Description

Technical Field

[0001] This invention relates to the field of sewing machinery technology, and in particular to a fabric cutting machine with a magnetic fabric locking device. Background Technology

[0002] A fabric cutter is a device used to cut fabric. It is widely used in the clothing, textile, leather, and plastic industries, and is mainly used to cut raw materials such as cotton, linen, synthetic leather, silk, and knitwear. It can also cut carpets, towels, bed sheets, plastic films, and many other materials.

[0003] In the current fabric cutting process, in order to improve the cutting efficiency of the fabric, the fabric needs to be stretched from both sides during cutting. Because there is no lateral fabric locking mechanism, the fabric cut will be deformed after cutting, resulting in insufficient precision in cutting the fabric. Furthermore, the fabric cut on the market cannot be stably controlled during cutting, making the operation very troublesome. Moreover, the separation control is also inconvenient and the scope of application is very limited. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to solve the problems existing in the background art, an improved fabric cutting machine with a magnetic fabric locking device is provided. This solves the problem that in the current fabric cutting process, the lack of a lateral fabric locking mechanism causes the fabric cut to deform after cutting, resulting in insufficient fabric cutting accuracy. Furthermore, the fabric cut on the market cannot be stably controlled during cutting, making the operation very troublesome, and the separation control is also inconvenient and the scope of application is very limited.

[0005] The technical solution adopted by this invention to solve its technical problem is: a fabric cutting machine with a magnetic fabric locking device, including an operating platform, a fabric cutting machine body, an adjusting motor, a drive motor, a permanent magnet, and a fabric rolling roller. A detachable transverse fabric cutting track is bolted to the upper surface of the operating platform. A lateral assembly frame for installing the fabric rolling roller is bolted to the right side of the upper surface of the operating platform. The fabric cutting machine body is movably connected to the detachable transverse fabric cutting track through a central guide wheel controlled by the drive motor at the bottom. Lateral storage boxes with built-in roll drums are bolted to the outer walls on both sides of the fabric cutting machine body. A central guide groove that cooperates with the central guide wheel is opened on the upper surface of the detachable transverse fabric cutting track. Lateral adjustment chambers with built-in angle adjustable assembly seats are symmetrically opened on both sides of the central guide groove inside the detachable transverse fabric cutting track.

[0006] The lateral adjustment chamber has symmetrical lateral assembly holes on both sides of its inner wall. The angle-adjustable assembly seat includes a flip assembly plate, a circular assembly frame fixed at both ends of the flip assembly plate, and a lateral assembly rotating shaft fixed at both ends of the flip assembly plate. The side wall of the flip assembly plate has a lateral assembly slot for mounting permanent magnets.

[0007] The detachable transverse fabric track has a lateral assembly cylinder for installing an adjustment motor bolted to its outer side surface. The outer shaft of the adjustment motor and the lateral assembly shaft are connected by a belt drive pulley set.

[0008] The outer surface of the chain drum is wound with a locking chain belt composed of multiple iron locking cloth plates connected in a movable manner. The inner side of the side storage box is symmetrically provided with circular mounting grooves for movably assembling the chain drum. A lateral coil spring for controlling the elastic rotation and reset of the chain drum is installed on the inner side of the circular mounting groove.

[0009] The side storage box has an external feeding port on its outer side, and the top of the outer side of the locking chain belt is fixedly connected to a T-shaped top limiting frame outside the external feeding port.

[0010] The lower surface of the fabric cutting machine body has an L-shaped bottom guide protrusion that protrudes towards the central guide groove. A side cutting blade is elastically fitted inside the bottom guide protrusion. A transverse adjustment groove for installing the side cutting blade is opened above the bottom guide protrusion on the lower surface of the fabric cutting machine body. A transverse guide rod with a compression spring on the outside is fixedly connected inside the transverse adjustment groove. A top guide block is fixedly connected to the upper end of the side cutting blade. The side cutting blade is slidably connected to the transverse adjustment groove through the top guide block, which is fitted around the outside of the transverse guide rod.

[0011] The detachable transverse fabric cutting track has a lateral threaded through hole with a built-in lateral locking bolt on its outer side surface. The upper surface of the detachable transverse fabric cutting track has an arc-shaped top limiting opening that matches the top limiting frame. An arc-shaped extrusion strip protruding towards the arc-shaped top limiting opening is fixedly connected to the outer side of the circular assembly frame.

[0012] The inner side of the lateral adjustment chamber is provided with an arc-shaped internal linkage groove that communicates with the arc-shaped top limiting port.

[0013] The inner walls on both sides of the central guide groove are provided with lateral limiting grooves, and the bottom guide protrusion has an integral lateral limiting slider that protrudes towards the lateral limiting groove on both sides.

[0014] The beneficial effects of this invention are:

[0015] (1) The fabric cutting machine of the present invention has a detachable transverse fabric cutting track bolted on the upper surface of the operating platform, making its installation position simpler and more convenient, and its application range wider;

[0016] (2) A side storage box with a built-in winding drum is bolted to the outer wall on both sides of the fabric cutting machine body. An angle-adjustable mounting seat controlled by an adjustable motor is set inside the detachable transverse fabric cutting track. A permanent magnet is installed on the angle-adjustable mounting seat. By changing the distance between the permanent magnet and the locking chain, the locking chain and the detachable transverse fabric cutting track can be quickly controlled to separate and join. The operation is simple and convenient. It can follow the fabric cutting machine body to move and retract. The control linkage is strong and the stability is greatly improved.

[0017] (3) The adjustable motor drives the angle-adjustable assembly base to rotate, which can quickly separate and join, so that no power is consumed during the locking process, greatly reducing energy consumption;

[0018] (4) A T-shaped top limiting frame is fixedly connected to the top of the outer side of the lock fabric chain belt. The arc-shaped top limiting opening increases the assembly firmness of the top of the lock fabric chain belt and prevents displacement during horizontal cutting. At the same time, the arc-shaped extrusion strip on the outer side of the circular assembly frame can quickly squeeze out and separate, making it easy to store and use. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0025] Figure 1 , Figure 2 and Figure 3The fabric cutting machine shown includes an operating platform 1, a fabric cutting machine body 2, an adjusting motor 3, a drive motor 4, a permanent magnet 5, and a fabric rolling roller 6. A detachable transverse fabric cutting track 7 is bolted to the upper surface of the operating platform 1. A lateral assembly frame 8 for mounting the fabric rolling roller 6 is bolted to the right side of the upper surface of the operating platform 1. The fabric cutting machine body 2 is movably connected to the detachable transverse fabric cutting track 7 via a central guide wheel 9 controlled by the drive motor 4 at the bottom. Lateral storage boxes 11 with built-in chain drums 10 are bolted to the outer walls on both sides of the fabric cutting machine body 2. A central guide groove 12 that cooperates with the central guide wheel 9 is opened on the upper surface of the detachable transverse fabric cutting track 7. Lateral adjustment chambers 13 with built-in angle adjustable mounting seats are symmetrically opened on both sides of the central guide groove 12 inside the detachable transverse fabric cutting track 7.

[0026] The drive motor 4 drives the fabric cutting machine body 2 to cut the fabric. At the same time as cutting, the fabric on both sides of the cutting end is magnetically locked. Then it can be cut from one end to the other end, and then cut back from the other end to one end.

[0027] Furthermore, to facilitate rotational adjustment, lateral assembly holes are symmetrically provided on the inner walls of both sides of the lateral adjustment chamber 13. The angle-adjustable assembly seat includes a flip assembly plate 14, a circular assembly frame 15 fixed at both ends of the flip assembly plate 14, and a lateral assembly rotating shaft fixed at both ends of the flip assembly plate 14. A lateral assembly slot 16 for installing the permanent magnet 5 is provided on the side wall of the flip assembly plate 14.

[0028] Furthermore, in order to cooperate with the lateral adjustment transmission, a lateral assembly cylinder 17 for installing the adjustment motor 3 is bolted to the outer side of the detachable transverse fabric track 7. The outer shaft of the adjustment motor 3 and the lateral assembly shaft are connected by a belt drive pulley set 18.

[0029] Furthermore, in order to facilitate elastic rotation and reset, the locking chain 19 can be quickly wound into the side storage box 11. The outer surface of the chain drum 10 is wrapped with a locking chain 19 consisting of 7 iron locking plates connected movably. The inner side of the side storage box 11 is symmetrically provided with circular mounting slots for movably assembling the chain drum 10. A lateral coil spring 20 for controlling the elastic rotation and reset of the chain drum 10 is installed on the inner side of the circular mounting slot.

[0030] Furthermore, in order to cooperate with the top limit, an external feeding port 21 is provided on the outer side of the side storage box 11, and a T-shaped top limit frame 22 is fixedly connected to the outer top of the locking chain belt 19 outside the external feeding port 21.

[0031] It allows for easy locking at both ends and flexible reset, facilitating back-and-forth cutting.

[0032] like Figure 4As shown, in order to cooperate with the elastic cutting, the lower surface of the fabric cutting machine body 2 has an L-shaped bottom guide protrusion 23 that protrudes towards the central guide groove 12. The bottom guide protrusion 23 is elastically fitted with a side cutting blade 24. The lower surface of the fabric cutting machine body 2 is provided with a transverse adjustment groove 25 above the bottom guide protrusion 23 for installing the side cutting blade 24. The transverse adjustment groove 25 is fixedly connected to a transverse guide rod 27 with an external compression spring 26. The upper end of the side cutting blade 24 is fixedly connected to a top guide block 28. The side cutting blade 24 is slidably connected to the transverse adjustment groove 25 through the top guide block 28 on the outside of the transverse guide rod 27.

[0033] Furthermore, in order to cooperate with the rotational extrusion, the outer side of the detachable transverse fabric cutting track 7 is provided with a lateral threaded through hole for the built-in lateral locking bolt 29, and the upper surface of the detachable transverse fabric cutting track 7 is provided with an arc-shaped top limiting port 30 that cooperates with the top limiting frame 22. An arc-shaped extrusion strip 31 protruding towards the arc-shaped top limiting port 30 is fixedly connected to the outer side of the circular assembly frame 15.

[0034] The adjusting motor 3 drives the circular assembly frame 15 to rotate, causing the arc-shaped extrusion strip 31 to rotate into the arc-shaped top limiting opening 30. Then, the top limiting frame 22 is extruded from the arc-shaped top limiting opening 30. First, the top limiting frame 22 is inserted into the arc-shaped top limiting opening 30. Then, the driving motor 4 drives the fabric cutting machine body 2 along the detachable transverse fabric cutting track 7. When the fabric cutting machine body 2 moves horizontally, the locking chain 19 is pulled out. Then, the adjusting motor 3 drives the circular assembly frame 15 to rotate, and the arc-shaped extrusion strip 31 leaves the arc-shaped top limiting opening 30. Then, the permanent magnet 5 is located on the outermost side, so that it can be magnetically attracted and fixed with the locking chain 19. Then, the fabric on both sides can be fixedly locked.

[0035] Furthermore, in order to facilitate rotation, an arc-shaped internal linkage groove 32 is provided on the inner side of the lateral adjustment chamber 13, which is connected to the arc-shaped top limiting port 30.

[0036] Furthermore, in order to facilitate lateral sliding and limiting, lateral limiting grooves 33 are provided on the inner walls of both sides of the central guide groove 12, and the bottom guide protrusion 23 has an integral lateral limiting slider 34 protruding towards the lateral limiting groove 33 on both sides.

[0037] The present invention discloses a fabric cutting machine with a magnetic fabric locking device. A detachable transverse fabric cutting track 7 is bolted to the upper surface of the operating platform 1, making its installation simpler and more convenient, and its application range wider. Side storage boxes 11 with built-in chain drums 10 are bolted to the outer walls on both sides of the fabric cutting machine body 2. An angle-adjustable mounting base controlled by an adjusting motor 3 is provided inside the detachable transverse fabric cutting track 7. A permanent magnet 5 is mounted on the angle-adjustable mounting base, and the separation and engagement of the locking chain 19 with the detachable transverse fabric cutting track 7 are quickly controlled by changing the distance between the permanent magnet 5 and the locking chain 19. It is simple and convenient to operate, and can follow the fabric cutting machine body 2 to retract and extend. It has strong control linkage and greatly improved stability. The adjustable motor 3 drives the angle adjustable assembly seat to flip, which can quickly separate and join. It does not consume electricity during the locking process, which greatly reduces energy consumption. A T-shaped top limiting frame 22 is fixedly connected to the top of the outer side of the locking chain belt 19. The arc-shaped top limiting port 30 increases the assembly firmness of the top of the locking chain belt 19 and prevents displacement during horizontal cutting. At the same time, the arc-shaped extrusion strip 31 on the outer side of the circular assembly frame 15 can quickly squeeze out and separate, which is convenient for storage and use.
