[0022] Please refer to Figures 1-3This utility model provides a tape feeding and cutting device, which includes: a feeding track 10, an encoder 20, a feeding transmission assembly 30, a color mark sensor 40, a cutting assembly 50, and a control module (not shown). The feeding track 10 has a slot 11 for holding the tape G. The encoder 20 includes a counting roller 21 that extends into the slot 11 and contacts the tape G. The feeding transmission assembly 30 includes a driving roller 31, a driven roller 32, and a first drive source (not shown). The first drive source is preferably a motor, used to drive the driving roller 31 to rotate. The driving roller 31 and the driven roller 32 cooperate to drive the tape G to slide in the slot 11, thus feeding the tape G. When the tape G slides in the slot 11 of the feeding track 10, it can drive the counting roller 21 to roll, count, and transmit the data to the control module. The color mark sensor... The encoder 20 is used to identify the cutting mark on the webbing G. The cutting component 50 is located on the side of the feeding transmission component 30 away from the color mark sensor 40 and is used to cut the webbing G. The encoder 20, the first drive source, the color mark sensor 40 and the cutting component 50 are all electrically connected to the control module. When the color mark sensor 40 detects the cutting mark, it can send a signal to the control module. According to the count of the encoder 20, when the feeding transmission component 30 transports the cutting mark on the webbing G to the cutting position according to the set transmission value, the control module can control the first drive source to turn off, so that the active roller 31 and the driven roller 32 stop rotating. At this time, the control module can control the cutting component 50 to cut the webbing G.

[0023] In this embodiment, the tape feeding and cutting device can not only perform fixed-length cutting through the encoder 20, but also perform more precise mark-finding cutting of the webbing G through the dual feedback of the encoder 20 and the color mark sensor 40. The user only needs to make a cutting mark on the webbing G in advance according to the length requirements of the webbing G, and the tape feeding and cutting device can cut at the cutting mark to meet the different length requirements of the webbing.

[0024] In one specific embodiment, the feeding track 10 includes an inlet end and an outlet end, the webbing G can slide from the inlet end to the outlet end in the slot 11, the counting roller 21 is located at the inlet end of the feeding track 10, the color mark sensor 40 is located at the outlet end of the feeding track 10, and the color mark sensor 40 is located between the feeding transmission assembly 30 and the counting roller 21.

[0025] In a preferred embodiment, the discharge end is further provided with a limiting block 60, which is used to restrict the webbing G in the slot 11, thereby preventing the webbing G from arching at the discharge end and affecting the recognition of the color mark sensor 40, so as to reduce the cutting error.

[0026] For specific details, please refer to Figure 3The feeding track 10 includes a bottom 12 and two side portions 13. A slot 11 is formed between the bottom 12 and the two side portions 13. Both side portions 13 are provided with relief slots 131. The two ends of the limiting block 60 are received in the relief slots 131. The limiting block 60 can be fixed to the side portion 13 of the feeding track 10 by fasteners to limit the webbing G more stably.

[0027] Preferably, the limiting pressure block 60 is further provided with a through hole 61, which is directly opposite the color mark sensor 40, so that the color mark sensor 40 can identify the cutting marks on the webbing G through the through hole 61. In this embodiment, the limiting pressure block 60 is located below the color mark sensor 40, where the stability of the webbing G is optimal, and the color mark sensor 40 identifies the cutting marks on the webbing G through the through hole 61, resulting in the most accurate identification result.

[0028] In one specific embodiment, the cutting component 50 includes a first cutter 51, a second cutter 52 opposite to the first cutter 51, and a second drive source 53 that drives the first cutter 51. The second drive source 53 is electrically connected to the control module. The second drive source 53 is preferably a cylinder. The control module can realize the cutting action of the webbing G by controlling the movement of the cylinder.

[0029] Preferably, the second cutter 52 is also connected to an ultrasonic transducer 54, which is electrically connected to the control module. It should be noted that in traditional cutting methods, cold cutting results in frayed edges, while hot cutting creates hard granules and uneven cuts. However, this embodiment, using the ultrasonic transducer 54, achieves burr-free cuts, smoother cuts, and better cutting results and finished product quality.

[0030] In a preferred embodiment, reference may be made to Figure 3 To prevent the webbing G from drooping directly after extending between the driving roller 31 and the driven roller 32, the webbing cutting device also includes a support member 70. The support member 70 is used to support the webbing G extending between the driving roller 31 and the driven roller 32, so that the webbing G can be kept in a relatively straight state after extending between the driving roller 31 and the driven roller 32, thereby improving the cutting quality and effect.

[0031] In one specific embodiment, the tape feeding and cutting device further includes a housing 80, on which the feeding transmission assembly 30, encoder 20, color mark sensor 40, control module, and support 70 are all mounted. More specifically, see [reference needed]. Figure 1 The first cutter 51 and the second drive source 53 can also be installed on the chassis 80.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
