[0002] During the production process of fabrics, there will be many loose fiber yarns of different lengths on the surface of the fabrics. During the fabric printing and dyeing process, the presence of loose fibers will cause various disadvantages. Loose fibers are easy to fall into the alkali solution, causing the impurities in the alkali solution to gradually increase, making it difficult to recover the alkali solution; fiber yarns fall into the printing paste, which is easy to cause problems with the paste and the knife, affecting the clarity of the pattern.

[0003] At the same time, the existence of fiber yarns of different lengths will also affect the flatness of the fabric, so the fiber yarns need to be trimmed. Under normal circumstances, the fabric is placed on a workbench, and then a cutting knife is used to pass over the upper surface of the fabric to cut the fiber yarns. The fiber yarns are affected by gravity and will collapse on the surface of the fabric. This type of fiber yarn cutting cannot ensure the uniformity of the fiber yarn length. After cutting, the fiber yarns will fall to the surface of the fabric, and the cut fiber yarns cannot be collected, resulting in an unsatisfactory trimming effect of the fabric fiber yarns.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The present embodiment provides a fabric trimming machine, which is mainly used for trimming fiber yarns on fabrics to improve the trimming effect of the fiber yarns.

[0029] like Figure 1 and Figure 2 As shown, it includes a workbench 10, which is used to place the fabric horizontally and fix the fabric on the table top of the workbench 10, and also includes a three-axis movable table 11 that moves on the workbench 10, and a hair trimmer 2 is installed on the three-axis movable table 11, wherein the three-axis movable table 11 can drive the hair trimmer 2 to move in the X-axis, Y-axis and Z-axis, and the hair trimmer 2 includes a hair trimming component 22 and a driving component 21 detachably connected to the hair trimming component 22, the hair trimming component 22 is provided with a blade assembly 225 and a guide cover 222, the driving component 21 is provided with a filter screen 212, a driving component that drives the blade assembly 225 to rotate, and a negative pressure component that provides negative pressure for the hair trimming component 22, after the hair trimming component 22 and the driving component 21 are assembled, the guide cover 222 and the filter screen 212 form a storage cavity 223 for storing fiber yarns.

[0030] Through the above arrangement, the height of the trimmer 2 is adjusted by the three-axis moving platform 11, where the height is the Z-axis height. The axis of the trimmer 2 is arranged along the Z-axis direction. When the height of the trimmer 2 is adjusted, the three-axis moving platform 11 can be used to drive the trimmer 2 to move in the XOY plane. At this time, the negative pressure component generates negative pressure at the position of the trimming component 22, such as Figure 2As shown, at this time, the air flow flows from the bottom to the top of the trimmer 2, and then the fiber yarn stands upright. At this time, the fiber yarn extends into the trimming component 22, and the driving component in the driving component 21 drives the blade component 225 to rotate at a high speed, thereby cutting off the excess part of the fiber yarn, and the air flow drives the cut fiber yarn to move upward, and then passes through the guide cover 222 and is blocked by the filter screen 212, so that the cut fiber yarn falls into the storage chamber 223, thereby realizing precise cutting of the fiber yarn, and being able to collect the cut fiber yarn, thereby improving the cutting effect of the fabric fiber yarn.

[0031] It is worth mentioning here that the negative pressure component can also absorb the loose fiber yarns on the fabric, so that the loose fiber yarns are separated from the fabric, thereby improving the cleaning effect of the fiber yarns.

[0032] Specifically, in order to realize the detachable installation of the driving component 21 and the hair trimming component 22, in this embodiment, as shown in FIG. Figure 2 As shown, the driving component 21 includes a first housing 211, and the hair trimming component 22 includes a second housing 221. Figure 5 and Figure 6 As shown, a mounting track 218 is disposed on the peripheral wall of the first shell 211 , and a locking block 2211 is fixedly disposed on the inner wall of the second shell 221 . When the driving component 21 and the hair trimming component 22 are assembled, the locking block 2211 can be plugged into the mounting track 218 .

[0033] It is worth pointing out here that Figure 5 As shown, the mounting track 218 includes a first track 2181 and a second track 2182, wherein the first track 2181 is arranged along the axial direction of the first shell 211, and the second track 2182 is arranged along the circumferential direction of the first shell 211, and the first track 2181 is connected to the second track 2182; when the hair trimming component 22 is assembled with the driving component 21, the locking block 2211 on the second shell 221 is inserted into the first track 2181, and then the hair trimming component 22 is arranged along the axial direction of the first shell 211, and the locking block 2211 is inserted into the second track 2182, and then the second shell 221 is rotated along the circumferential direction of the first shell 211, so that the locking block 2211 is inserted into the second track 2182, so as to realize the locking of the first shell 211 and the second shell 221.

[0034] In order to prevent the first shell 211 and the second shell 221 from rotating relative to each other and to separate the driving component 21 from the hair trimming component 22, in the present embodiment, a locking groove 2183 and a first spring washer 219 are further included, wherein the first spring washer 219 is sleeved on the outer side of the first shell 211, and the locking groove 2183 is arranged on the second track 2182 and close to the side of the hair trimming component 22. When the hair trimming component 22 is assembled with the driving component 21, the first shell 211 and the second shell 221 squeeze the first spring washer 219 to deform the first spring washer 219. At this time, the first spring washer 219 has a reverse thrust on the second shell 221, and then the locking block 2211 is inserted into the locking groove 2183 to realize the locking of the driving component 21 and the hair trimming component 22, thereby preventing the hair trimming component 22 and the driving component 21 from rotating relative to each other.

[0035] When the fiber yarns on the fabric are trimmed, the trimming component 22 can be removed from the driving component 21. At this time, the storage cavity 223 surrounded by the filter screen 212 and the guide cover 222 is opened, and the fiber yarns accumulated in the storage cavity 223 can be driven to achieve the cleaning of the fiber yarns.

[0036] Since the blade assembly 225 is installed in the hair trimming component 22, the driving component is installed in the driving component 21, and the driving component 21 is detachably connected to the hair trimming component 22, in order to realize the high-speed rotation of the blade assembly 225, in this embodiment, Figure 2 As shown, the driving assembly includes a connector 217, a motor 216 and a connector seat 224, wherein the motor 216 is fixedly installed in the inner cavity of the first housing 211, the connector 217 is installed on the output shaft of the motor 216 and the connector 217 passes through the filter 212 and is located in the storage cavity 223, the connector seat 224 is located in the second housing 221, and the blade assembly 225 is installed on the connector seat 224, as shown in FIG. Figure 6 As shown, a connecting hole 2241 is provided on the connecting seat 224. When the driving component 21 and the hair trimming component 22 are assembled, the connecting head 217 is inserted into the connecting hole 2241 to realize the connection between the connecting head 217 and the connecting seat 224. The rotation of the motor 216 can drive the blade assembly 225 to rotate at high speed through the connecting head 217 and the connecting seat 224.

[0037] Since the connector 217 passes through the filter screen 212 and extends into the storage chamber 223, in this embodiment, Figure 7 As shown, after the output shaft of the motor 216 passes through the filter 212, the connector 217 is sleeved on the output shaft of the motor 216, and then the connector 217 is fixed to the output shaft of the motor 216 by gluing or screwing.

[0038] In order to fix the motor 216, in this embodiment, as shown in FIG. Figure 2 and Figure 7 As shown, a mounting frame 213 is fixedly provided in the first shell 211 , wherein the motor 216 is fixedly mounted on the mounting frame 213 .

[0039] After the driving component 21 and the hair trimming component 22 are installed, in order to form a negative pressure at the position of the hair trimming component 22, in this embodiment, Figure 2 and Figure 7 As shown, the negative pressure component includes a fan blade 215, wherein the fan blade 215 is installed in the inner cavity of the first shell 211, and the fan blade 215 is fixedly installed on the output shaft of the motor 216. When the hair trimmer 2 is working, the motor 216 drives the fan blade 215 to rotate at a high speed. At this time, the fan blade 215 drives the airflow to flow along the axis of the motor 216, so that the airflow flows from the bottom to the top of the hair trimmer 2.

[0040] It is worth noting that the side of the hair trimming component 22 is the bottom of the hair trimmer 2 , and the side of the driving component 21 is the top of the hair trimmer 2 .

[0041] In order to prevent the high-speed rotation of the fan blades 215 from injuring the operator, in this embodiment, Figure 2 and Figure 7 As shown, a first end cover 214 is fixedly mounted on the top of the first shell 211 , wherein the first end cover 214 is provided with a plurality of holes to facilitate the airflow in the hair trimmer 2 to flow outward from the first end cover 214 .

[0042] Since the blade assembly 225 is installed in the second shell body 221, the high-speed rotation of the blade assembly 225 is likely to injure the staff. Therefore, in this embodiment, a second end cover 226 is provided at the bottom of the second shell body 221. The second end cover 226 is provided with a plurality of mesh holes so that the external airflow can enter the trimmer 2 through the mesh holes of the second end cover 226. At this time, the mesh holes on the second end cover 226 can also allow upright fiber yarns to pass through so that the blade assembly 225 can cut the fiber yarns.

[0043] It is worth noting that the second end cover 226 and the second housing 221 are detachable to facilitate replacement of the blade assembly 225. Specifically, Figure 8 As shown, the connection method between the second end cover 226 and the second shell 221 is consistent with the connection method between the second shell 221 and the first shell 211, wherein a second elastic pad 227 is further provided between the second end cover 226 and the second shell 221 to prevent relative movement between the second shell 221 and the second end cover 226.

[0044] In order to achieve the replacement of the blade assembly 225, in this embodiment, as shown in FIG. Figure 3 and Figure 8As shown, a plug-in rod 2242 is fixedly provided on the connecting seat 224, wherein a locking head 2243 is fixedly provided on the side of the plug-in rod 2242 close to the blade assembly 225, and a mounting hole 2251 is provided on the blade assembly 225 for the plug-in rod 2242 and the locking head 2243 to pass through, and also includes a third spring pad 228 fixedly installed on the connecting seat 224, wherein the plug-in rod 2242 is provided in two groups and is elastic.

[0045] Through the above-mentioned arrangement, when the blade assembly 225 is being installed, the locking head 2243 on the plug-in rod 2242 is pushed toward the axis side of the connecting seat 224 so that the locking head 2243 can pass through the mounting hole 2251, and then the blade assembly 225 is pushed toward one side of the connecting seat 224 so that the end wall of the blade assembly 225 abuts against the third spring pad 228 and squeezes the third spring pad 228. At this time, the locking head 2243 rebounds, and the locking surface of the locking head 2243 abuts against the end wall of the blade assembly 225 close to the workbench 10, thereby realizing the installation of the blade assembly 225.

[0046] The blade assembly 225 is provided with a plurality of blades 2253 evenly distributed around the connecting seat 224 , and the blades 2253 are used to cut the fiber yarn.

[0047] In order to facilitate the installation of the locking head 2243 and the blade assembly 225, in this embodiment, as shown in FIG. Figure 3 As shown, the locking head 2243 is provided with an inclined guide surface 22431, and the inner wall of the mounting hole 2251 is provided with a guide surface 2252, wherein the guide surface 2252 is a conical surface.

[0048] Through the above-mentioned arrangement, when the blade assembly 225 is being installed, the mounting hole 2251 of the blade assembly 225 is aligned with the locking head 2243, so that the guide bevel 22431 of the locking head 2243 abuts against the guide surface 2252, and then the blade assembly 225 is pushed toward the connecting seat 224. At this time, the locking head 2243 moves toward the axis of the mounting hole 2251 to facilitate the locking head 2243 to pass through the mounting hole 2251. When the locking head 2243 passes through the mounting hole 2251, the locking surface on the locking head 2243 abuts against the end wall of the blade assembly 225, thereby locking the blade assembly 225 and fixing the blade assembly 225.

[0049] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
