[0026] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Refer to the instruction manual Figures 1 to 6 A shearing mechanism includes a shearing component 1 installed on a pad 3, the shearing component 1 includes a shearing panel 11, a transmission roller 12 is installed on the shearing panel 11, a cross frame 13 is provided on one side of the transmission roller 12, a linear driver 131 is fixedly installed on the cross frame 13, a tool 14 is fixedly connected to the output end of the linear driver 131, and the tool 14 is movably arranged on one side of the shearing panel 11, a support seat 15 is provided on one side of the linear driver 131, and the support seat 15 is located below the cross frame 13; a glue coating component 4 is installed on the support seat 15, and the glue coating component 4 is located between the shearing panel 11 and the support seat 15.

[0028] It should be noted that the transmission roller 12 includes a driving motor and a pressure roller. The driving motor drives the pressure roller to rotate and can convey the woven fabric in the direction of the tool 14. The conveying distance of the woven fabric is adjusted according to the rotation of the pressure roller. This is an existing mature technology. Vertical support frames are installed at both ends above the pad 3. The shear panel 11, the cross frame 13 and the two ends of the support seat 15 are respectively fixed on two sets of vertical support frames. The support seat 15 is located between the shear panel 11 and the cross frame 13. The linear drive 131 is an electric push rod or a cylinder, which is used to drive the tool 14 to move up and down. The gluing component 4 is used to apply glue to the woven fabric.

[0029] In this embodiment, the implementation scenario is specifically as follows: the woven fabric is conveyed toward the tool 14 through the transmission roller 12, and when the cutting part moves to the bottom of the glue coating component 4, the conveying is stopped, and glue is applied to the cutting part of the woven fabric through the glue coating component 4, and the glue is waited for to solidify and fix. The cutting part becomes the glue coating part, and then the woven fabric is continued to be conveyed, and the glue coating part moves to below the tool 14, and the conveying is stopped. The tool 14 is driven downward by a linear drive 131 to shear the glue coating part of the woven fabric. The whole process is to firstly glue the cutting part of the woven fabric, wait for the glue to solidify and fix, and finally shear the glued cutting part, so as to effectively avoid the loosening of the cutting part of the woven fabric after shearing.

[0030] Furthermore, the glue coating component 4 includes a glue box 41 , the bottom of the glue box 41 is connected to a glue drop head 42 , and the glue drop head 42 is located above the shear panel 11 , and an air drying component is provided on one side of the glue box 41 .

[0031] It should be noted that a switch valve is installed inside the glue box 41, and the switch valve can adopt an electrically controlled valve in the prior art. The inlet of the switch valve is connected to the glue box 41, and the outlet of the switch valve is connected to the glue dripping head 42. Opening the switch valve can allow the glue in the glue box 41 to drip onto the cutting part of the woven fabric through the glue dripping head 42.

[0032] Furthermore, the air-drying component includes an air supply box 43 , the bottom of the air supply box 43 is connected to a blowing plate 44 , and the bottom end of the blowing plate 44 is inclined toward the glue dripping head 42 .

[0033] It should be noted that the air supply box 43 is connected to an external hair dryer, and cold air is delivered to the blowing plate 44 through the air supply box 43. The blowing plate 44 blows the cold air toward the glue-coated part of the woven fabric to accelerate the solidification and molding speed of the glue.

[0034] After the cutter 14 shears the woven fabric with glue, adhesive debris is easily adhered to its surface. If it is not cleaned in time, after a long period of processing, the accumulated adhesive debris will affect the shearing effect of the cutter 14;

[0035] Refer to the instruction manual Figure 7 and Figure 8 In order to solve this problem, this embodiment provides the following technical solution: a scraper assembly 5 is provided on one side of the glue coating assembly 4, and the scraper assembly 5 is located between the tool 14 and the support seat 15, and the output end of the scraper assembly 5 abuts against the side of the tool 14 for shearing.

[0036] It should be noted that the scraper assembly 5 is used to scrape off the adhesive debris on the surface of the cleaning tool 14 .

[0037] Furthermore, the scraper assembly 5 includes a support rod 51, on which a collecting box 511 is detachably mounted, and a scraper blade 512 is rotatably connected to one side of the collecting box 511. The tool 14 includes a tool holder 141, on which a blade 142 is detachably mounted, and one end of the scraper blade 512 abuts against a side of the blade 142 close to the support rod 51.

[0038] It should be noted that the top of the collection box 511 and one end close to the scraper 512 are open, the upper surface of the scraper 512 is an inclined surface, the scraper 512 can be flipped upward, and the bottom surface of the scraper 512 is blocked by the bottom surface inside the collection box 511, so that the scraper 512 cannot be flipped downward.

[0039] Furthermore, a mounting seat 16 is fixedly provided on the support seat 15, and a guide opening 161 is opened on the side of the mounting seat 16 close to the support rod 51. The top end of the support rod 51 is fixedly connected to the movable block 52, and one end of the movable block 52 is slidably arranged inside the guide opening 161. A linear driver 2 53 is installed inside the guide opening 161, and the output end of the linear driver 2 53 is fixedly connected to one end of the movable block 52.

[0040] It should be noted that the second linear driver 53 is a vibration motor, a linear screw or an electric push rod, and the second linear driver 53 is used to drive the movable block 52 to move up and down, so that the scraper 512 can continuously scrape off the adhesive debris on the surface of the blade 142.

[0041] In this embodiment, the implementation scenario is specifically as follows: the blade 142 is fixed by the tool holder 141, and the blade 142 shears the woven fabric. When shearing, the blade 142 slides along the outer side of the edge of the shearing panel 11, and the surface of the blade 142 close to the outer side of the edge of the shearing panel 11 is the shearing surface. After shearing the woven fabric with glue, the shearing surface is easy to adhere to adhesive debris. When the blade 142 is retracted upward, under the reverse push of the adhesive debris on the surface, the scraper 512 flips upward to make room. When the blade 142 moves downward to shear, the tip of the scraper 512 scrapes off the adhesive debris on the shearing surface, and collects the adhesive debris into the collection box 511 through the top inclined surface. The collection box 511 is regularly disassembled for cleaning. The overall scraping and cleaning can be performed before each shearing by the blade 142 to ensure the shearing effect of the shearing surface of the blade 142.

[0042] Refer to the instruction manual Figure 1 and Figure 2 A computerized flat knitting machine includes a knitting assembly 2, which is arranged on one side of a pad 3, and an output end of the knitting assembly 2 is opposite to a side of a shearing panel 11 away from a knife 14.

[0043] It should be noted that the weaving component 2 weaves the raw materials into a woven fabric, and transports the woven fabric to the shearing component 1 on the support platform 3.

[0044] Furthermore, the weaving assembly 2 comprises a frame, on which a wire guide frame 21 is mounted, a shuttle needle frame 22 is disposed at the output end of the wire guide frame 21 , and a pulling frame 23 is disposed at the output end of the shuttle needle frame 22 .

[0045] It should be noted that the wire guide frame 21 introduces the raw materials, the shuttle needle frame 22 performs the weaving process, and the obtained knitted fabric is pulled out by the pulling frame 23.

[0046] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
