Description

Technical Field

[0001] The utility model relates to the technical field of sewing equipment, in particular to a cutting device and a template machine. Background Art

[0002] The template machine is a sewing equipment that combines clothing template technology. It has the advantages of large format and high speed. It can not only improve the operating efficiency of the production line, but also meet the requirements of various production processes. It has multiple automatic sewing functions, simple operation, and low requirements for workers. It is widely used in the sewing field.

[0003] Existing template machines have a cutting device installed below the machine head and above the workbench. When the sewing is complete and the material needs to be cut, the cutting device descends via a lifting mechanism, activating the cutter to cut the material. When cutting is complete, the cutting device ascends and returns to its original position via the lifting mechanism. Most existing template machines' cutting devices utilize a single-edged cutting method. During cutting, the lower and upper rotating motors are electronically controlled to rotate synchronously to cut the fabric. This electronic control has certain errors, so slotting is commonly performed on the mounting plate of the lower rotating motor. However, slotting leaves the fabric near the blades without support, resulting in more burrs during cutting and affecting the cutting effect. Utility Model Content

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] The present invention discloses a cutting device. Figure 1 and 2 As shown, the machine comprises a lower rotary motor 1, a lower support sleeve 2, and a flexible block 3. The lower rotary motor 1 includes a lower output shaft 11, which is coaxially connected to the lower support sleeve 2 and cylindrically shaped. A fixing groove 41 is provided at the end of the lower support sleeve 2, distal from the lower output shaft 11. The flexible block 3 is secured to the fixing groove 41. When cutting fabric, the flexible block 3 provides support for the fabric through its elastic force, minimizing deformation and achieving a better cutting effect.

[0043] As attached Figure 3 As shown, the lower support sleeve 2 is provided with a connecting flange 21 at one end away from the lower output shaft 11. The cutting device also includes a lower support plate 4, which is coaxially arranged with the connecting flange 21 and detachably connected to facilitate the disassembly and assembly of the lower support plate 4.

[0044] A fixing groove 41 is formed at the center of the lower support plate 4 , and the elastic block is supported by the lower support plate 4 .

[0045] As a preferred embodiment, as shown in the attached Figure 3 As shown, the lower support plate 4 and the connecting flange 21 are both disc-shaped, and the diameter of the lower support plate 4 is larger than the diameter of the connecting flange 21 to prevent the cutter 5 from scratching the lower support sleeve 2. Figure 4 As shown, the lower support plate 4 is provided with at least one mounting hole 42, and the connecting flange 21 is provided with at least one connecting hole; all the mounting holes 42 and all the connecting holes are axially corresponding one by one and penetrated by locking screws; each mounting hole 42 is provided with a recessed groove, and the head of the locking screw is arranged in the recessed groove; the height of the head of the locking screw is not higher than the depth of the recessed groove, ensuring that the head of the locking screw is completely recessed in the recessed groove of the mounting hole 42 to avoid collision between the locking screw and the cutter 5.

[0046] As attached Figure 4 and 5As shown, the fixing groove 41 is provided with a limiting step 411, and the flexible block 3 is provided with a limiting flange 31; when the flexible block 3 is inserted into the fixing groove 41, the limiting step 411 and the limiting flange 31 are axially opposed to each other, which is used to axially limit the position of the flexible block 3, thereby preventing the flexible block 3 from being completely sunk into the lower support sleeve 2 due to excessive force applied by the cutter 5, thereby improving the stability of the flexible block 3.

[0047] The flexible block 3 includes an elastic column, which is cylindrical and has a diameter larger than the diameter of the fixing groove 41. When the flexible block 3 is installed in the fixing groove 41, the elastic column is relatively thick and, under the extrusion of the fixing groove 41, the elastic column shrinks along its own radial direction and undergoes elastic deformation, so that the elastic column is firmly fixed in the fixing groove 41 by elastic force, avoiding the elastic column from being loosely fixed and affecting the cutting effect. In addition, there is no need to set up a separate connecting structure between the elastic column and the fixing groove 41. The structure is simple, convenient for processing and assembly, and the modification cost is low.

[0048] The flexible block 3 is specifically a rubber block to ensure that the flexible block 3 has sufficient elasticity. However, the material of the flexible block 3 is not limited thereto.

[0049] As attached Figure 1 As shown, the cutting device also includes a cutter 5 and an upper rotary motor 6. The tip of the cutter 5 is axially aligned with the center of the flexible block 3. This ensures that the flexible block 3 provides support for the fabric during cutting and prevents damage to the cutter 5 caused by alignment of the tip of the cutter with the flexible block 3. The upper rotary motor 6 includes an upper output shaft, to which the cutter 5 is connected, driving the cutter 5 in synchronous rotation. A transmission mechanism is provided between the upper output shaft and the handle of the cutter 5. The transmission mechanism can be a belt drive or a gear drive, which is not specifically limited here.

[0050] The cutting device also includes an upper speed detector, a lower speed detector 7, and a controller. The controller is respectively connected to the lower speed detector 7, the upper speed detector, the lower rotary motor 1, and the upper rotary motor 6. The upper speed detector is used to detect the current speed of the upper output shaft, and the lower speed detector 7 is used to detect the current speed of the lower output shaft 11. Both the upper speed detector and the lower speed detector 7 can be encoders.

[0051] When the upper speed detector detects that the current speed of the upper output shaft is inconsistent with the set speed, the speed detector feeds back a signal to the controller. After interpretation and processing, the controller sends a signal to the upper rotary motor 6 to adjust the speed of the upper rotary motor 6 until the current speed of the upper output shaft is consistent with the set speed. When the lower speed detector 7 detects that the current speed of the lower output shaft 11 is inconsistent with the set speed, the speed detector feeds back a signal to the controller. After interpretation and processing, the controller sends a signal to the lower rotary motor 1 to adjust the speed of the lower rotary motor 1 until the current speed of the lower output shaft 11 is consistent with the set speed. By adjusting the speeds of both the upper rotary motor 6 and the lower rotary motor 1 in real time, it is ensured that they always maintain synchronized speeds, thereby improving the cutting effect.

[0052] It should be noted that the controller should include a signal receiving unit, a signal determining unit, and a signal transmitting unit. The signal receiving unit is used to receive electrical signals transmitted by a detection component, such as the upper speed detector or the lower speed detector 7. The signal determining unit and the signal receiving unit are electrically connected so that the signal determining unit can determine whether the signal received by the signal receiving unit is a trigger signal. The signal transmitting unit and the signal determining unit are electrically connected so that the signal transmitting unit can transmit the judgment signal generated by the signal determining unit to an execution component, such as the lower rotating motor 1 or the upper rotating motor 6. The specific configuration of the signal receiving unit, the signal determining unit, and the signal transmitting unit can refer to the existing art; in this utility model, only the application scenarios of the above three components are changed, and no substantial improvement is made. Obviously, controllers with this structure are widely used in existing automatic control equipment, such as MCUs, DSPs, or single-chip microcomputers. The key point of this utility model is that the controller combines each detection component and each execution component in pairs.

[0053] The cutting device further includes a protective sleeve 8 and a lifting cylinder 9. The protective sleeve 8 is mounted on the outside of the cutter 5. The lifting cylinder 9 is connected to the protective sleeve 8 and is used to drive the protective sleeve 8 to rise and fall axially relative to the cutter 5, so that the protective sleeve 8 changes with the position of the cutter 5. The lifting cylinder 9 can be a pneumatic cylinder, but is not limited thereto.

[0054] The embodiment of the present invention also provides a template machine, including the above-mentioned cutting device, which has the same beneficial effects.

[0055] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0056] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
