Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sewing equipment technology, specifically relating to a novel cutting bed cutter head. Background Technology
[0002] With the gradual development of industry, the production of clothing and the cutting and sewing of fabrics have gradually shifted from manual to automated machine processing. The cutting bed cutter head is a tool that can move freely on the fabric while cutting it, and it is an indispensable piece of equipment in garment factories.
[0003] Since the cutting disc often needs to change direction during the moving cutting process, some existing cutting discs include two discs, an inner and an outer one. The direction of the cutting blade is changed by the rotation between the two discs. A bearing is usually installed between the two discs. Although this reduces the friction between the inner and outer discs, the bearings are expensive. In addition, after long-term use, the bearings and the discs generate a lot of heat, which may affect the normal use of the cutting disc.
[0004] In addition, during the cutting process, the cutting blades of the cutting disc will encounter resistance from the fabric. After a period of use, the blade edge and blade body will bend and deform, thus affecting the cutting effect on the fabric. Therefore, it is necessary to manually replace the new cutting blades at regular intervals, which is time-consuming, labor-intensive, and costly. Utility Model Content
[0005] To address the aforementioned problems, this utility model aims to provide a novel cutting bed cutter head, which optimizes the assembly structure of the inner and outer cutter heads, utilizes rotating wheels to achieve rotational engagement, reduces assembly difficulty, and also features an anti-bending structure for the cutting blades to promptly correct their bending, extend their service life, improve production efficiency, and reduce replacement and maintenance costs.
[0006] The technical problem solved by this utility model can be achieved by the following technical solution: a novel cutting bed cutter disc, including a cutter disc, a rotating mechanism and a cutting blade, the cutter disc including an inner cutter disc and an outer cutter disc, and a plurality of rotating wheels arranged between the inner cutter disc and the outer cutter disc, so that the inner cutter disc can rotate relative to the outer cutter disc; it also includes a horizontal sensing element, the horizontal sensing element being located in the middle of the inner cutter disc, the horizontal sensing element being used to sense the deformation of the cutting blade.
[0007] The horizontal sensing element is equipped with several limiting wheels, and the stroke cavity is formed between the limiting wheels. The cutting blade moves longitudinally in the stroke cavity.
[0008] When the cutting blade deforms, it comes into contact with any of the limit wheels, generating pressure. The limit wheels then transmit the pressure to the horizontal sensing element, causing the horizontal sensing element to be sensed.
[0009] A cavity is provided between the inner and outer cutter discs, and several rotating wheels are located in the cavity, with the outer ends of the rotating wheels abutting against the inner and outer cutter discs respectively.
[0010] It also includes a pressure plate, which is fixedly connected to the inner cutter disc and is located above the rotating wheel.
[0011] The outer tool disc includes an outer tool disc cover and an outer tool disc body. The outer tool disc cover is located on the upper part of the cavity. The outer tool disc body is provided with several connecting parts. The outer tool disc cover is provided with several corresponding connecting holes. The rotating wheel is provided on the outer tool disc body. The inner tool disc is located inside the outer tool disc body and rotates relative to the outer tool disc body.
[0012] It also includes a frame located above the outer cutter head, the frame including several connecting shafts, the connecting shafts passing through connecting holes and fixedly connected to the connecting part.
[0013] A rotating mechanism is installed inside the frame, which can rotate relative to the frame and drives the inner cutter head to rotate.
[0014] The rotating mechanism includes a rotating column, a bearing section, and a cover. The rotating column is installed in conjunction with the inner cutter disc, so that the rotating column and the inner cutter disc move together. The bearing section is located above the rotating column, and the cover is located above the bearing section to fix the bearing section.
[0015] When the rotating mechanism rotates, it synchronously drives the cutting blade to rotate as well.
[0016] Compared with the prior art, this utility model has the following advantages: This utility model optimizes the assembly structure of the inner and outer cutter discs, uses rotating wheels to achieve rotational cooperation, reduces assembly difficulty, and also has an anti-bending structure for the cutting blades to correct them in time, extend the service life of the cutting blades, improve production efficiency, and reduce replacement and maintenance costs.

Detailed Implementation
[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0020] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

[0021] Combined with appendix Figures 1 to 6 As shown, this embodiment discloses a novel cutting bed cutter head, including a cutter head 1, a rotating mechanism 2, and a cutting blade 3. The cutter head 1 includes an inner cutter head 11 and an outer cutter head 12. A plurality of rotating wheels 10 are arranged between the inner cutter head 11 and the outer cutter head 12, so that the inner cutter head 11 can rotate relative to the outer cutter head 12. Preferably, in this embodiment, the number of rotating wheels 10 is 3. The rotating wheels 10 are evenly arranged in the circumferential direction of the inner cutter head 11, which can reduce the friction and heat generation between the inner cutter head 11 and the outer cutter head 12. It also includes a horizontal sensing element 4, which is located in the middle of the inner cutter head 11 and is used to sense the deformation of the cutting blade 3.
[0022] In conjunction with the above, the horizontal sensing element 4 is provided with a plurality of limiting wheels 41, and a stroke cavity 42 is formed between the plurality of limiting wheels 41, in which the cutting blade 3 moves longitudinally. Preferably, in this embodiment, the number of limiting wheels 41 is four, and two are arranged in a group, one above the other, and the stroke cavity 42 between each group of limiting wheels 41 is slightly larger than the width of the cutting blade 3.
[0023] In summary, when the cutting blade 3 deforms, it comes into contact with any of the limiting wheels 41, generating pressure. The limiting wheel 41 transmits the pressure to the horizontal sensing element 4, causing the horizontal sensing element 4 to undergo a slight displacement in the horizontal direction. This causes the horizontal sensing element 4 to be sensed and sends a signal to the correction mechanism to correct the cutting blade 3. The correction mechanism adopts existing technologies such as the automatic cutting bed cutting blade guide mechanism disclosed in announcement number CN222613825U.
[0024] In conjunction with the above, a cavity 112 is also provided between the inner cutter head 11 and the outer cutter head 12, and a plurality of rotating wheels 10 are located in the cavity 112, with the outer ends of the rotating wheels 10 respectively abutting against the inner cutter head 11 and the outer cutter head 12.
[0025] In conjunction with the above, it also includes a pressure plate 111, which is fixedly connected to the inner cutter disc 11. The pressure plate 111 is located above the rotating wheel 10. In this embodiment, the pressure plate 111 partially covers the upper surface of the rotating wheel 10 to fix the inner cutter disc 11 and prevent the rotating wheel 10 from undergoing longitudinal displacement during rotation, which is beneficial to enhancing the stability of the cutter disc 1.
[0026] In conjunction with the above, the outer cutter disc 12 includes an outer cutter disc cover 121 and an outer cutter disc body 122. The outer cutter disc cover 121 and the outer cutter disc body 122 are fixedly connected by a number of fasteners. Preferably, in this embodiment, the fasteners are bolts. The outer cutter disc cover 121 is located on the upper part of the cavity 112. The outer cutter disc body 121 is provided with a number of connecting parts 123. The outer cutter disc cover 121 is provided with a number of connecting holes 124. In this embodiment, there are three connecting parts 123 and three connecting holes 124. The connecting holes 124 are located above the connecting parts 123. The rotating wheel 10 is disposed on the outer cutter disc body 122. The outer cutter disc cover 121 and the pressure plate 111 are in close contact with each other. The outer cutter disc 121 covers another part of the upper surface of the rotating wheel 10 and together with the pressure plate 111, prevents the rotating wheel 10 from undergoing longitudinal displacement during rotation. The inner cutter disc 11 is located inside the outer cutter disc body 122 and rotates relative to the outer cutter disc body 122.
[0027] In conjunction with the above, it also includes a frame 5 located above the outer cutter head 12. The frame 5 includes a plurality of connecting shafts 51. The connecting shafts 51 pass through the connecting holes 124 and are fixedly connected to the connecting part 123. In this embodiment, the number of connecting shafts 51 is 3. When the inner cutter head 11 rotates relative to the outer cutter head 12, the outer cutter head 12 will not rotate and will remain fixed relative to the inner cutter head 11.
[0028] In conjunction with the above, a rotating mechanism 2 is installed inside the frame 5. The rotating mechanism 2 can rotate relative to the frame 5 and is used to drive the inner cutter head 11 to rotate. In this embodiment, a driving device is connected to the rotating mechanism 2. The driving device can drive the rotating mechanism 2 to rotate and the cutter 3 to rise and fall. The cooperation relationship between the rotating mechanism 2, the cutter 3, and the driving device adopts the prior art.
[0029] In conjunction with the above, the rotating mechanism 2 includes a rotating column 21, a bearing portion 22, and a cover 23. The rotating column 21 is installed in conjunction with the inner cutter disc 11, so that the rotating column 21 and the inner cutter disc 11 move together. In this embodiment, the rotating column 21 and the inner cutter disc 11 are connected by an insertion connection; in other embodiments, other connection structures commonly used in the prior art can also be used. The bearing portion 22 is located above the rotating column 21 to optimize the rotation of the rotating column 21 and the cover 23 and reduce rotational friction. The cover 23 is located above the bearing portion 22 to fix the bearing portion 22.
[0030] Combined with the above installation structure, when the rotating mechanism 2 rotates, it synchronously drives the cutting blade 3 to rotate, so that the cutting edge of the cutting blade 3 and the stroke cavity 42 are always on the same straight line, so that the lines cut by the cutting blade 3 are continuous and uniform.
[0031] This utility model optimizes the assembly structure of the inner and outer cutter discs, uses rotating wheels to achieve rotational cooperation, reduces assembly difficulty, and also has an anti-bending structure for the cutting blades to correct them in time, extend the service life of the cutting blades, improve production efficiency, and reduce replacement and maintenance costs.
[0032] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
