Description

Technical Field

[0001] This utility model relates to the field of knitted hat processing technology, specifically to a cutting edge device for knitted hat processing. Background Technology

[0002] Knitted hats are hats made using a knitting method. Because the yarn used in knitted hats is mainly made of wool or animal hair, they are warmer.

[0003] However, the edge-cutting device for knitted hat processing proposed in application number 202420602481.2 still has certain defects in actual use. The above application uses a positioning cylinder to press the knitted hat body tightly with a positioning cover, and then uses a motor to drive the fixed knitted hat to rotate actively, thereby realizing the edge-cutting operation. However, the knitted hat body cover structure used in the above application is simple. Since the elasticity of knitted hats varies greatly depending on the yarn used, the above knitted hat body cover is difficult to expand to the maximum extent for knitted hats with different elasticity. As a result, the brim that cannot be effectively expanded will wrinkle, and in severe cases, it will cause the brim to be cut.

[0004] In view of this, a cutting device for knitted hat processing was designed to solve the above problems. Utility Model Content

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0033] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0034] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a cutting device for processing knitted hats. Example 1

[0035] Combination Figures 1 to 5 As shown, the present invention provides a cutting device for processing knitted hats, including a hat brim correction component 100 and a hat brim ring cutting component 200 disposed on the hat brim correction component 100. The hat brim correction component 100 provides a maximum expansion platform for knitted hats of different elasticity, and the hat brim ring cutting component 200 rings the brim raw edge after expansion and forced pressing.

[0036] The hat brim correction assembly 100 includes a support rod 1101, a bracket 120 fixedly installed on the support rod 1101, a hat bottom end protector 130 fixedly installed on the top of the bracket 120, a brim support ring 140 fixedly installed on the outside of the hat bottom end protector 130, an inner support rod 160 movably installed inside the support rod 1101, and a hat top end protector 150 fixedly installed on the outside of the inner support rod 160 and inserted into the hat bottom end protector 130.

[0037] A limiting head 1102 is fixedly installed on the top of the support rod 1101, and a pre-tightening stud 1106 is installed on the internal thread of the limiting head 1102;

[0038] The top of the support rod 1101 is provided with symmetrically distributed limiting slots, and the threaded section of the pre-tightening stud 1106 is adapted to pass through the limiting slots.

[0039] Two sliding pillars 1103 are fixedly installed on the inner wall of the cap bottom end protector 130, a positioning bolt 1104 is installed on the inner end of the sliding pillar 1103, and a gasket 1105 is provided outside the positioning bolt 1104 and bears pressure on the inner wall of the cap top end protector 150.

[0040] The cap edge circumferential cutting assembly 200 includes a sliding sleeve 210 movably installed in an annular groove, two outer frames 2101 fixedly installed on the sliding sleeve 210, a slider 2201 movably installed in the two outer frames 2101, a support leg 220 fixedly installed outside the slider 2201, an annular sleeve 230 fixedly installed at the bottom of the support leg 220, a circumferential cutting base 250 fixedly installed at the top of the annular sleeve 230, a base 2503 movably installed outside the circumferential cutting base 250, a vertical rod 2504 fixedly installed inside the base 2503, a second spring 2505 disposed outside the vertical rod 2504 and pressed on the circumferential cutting base 250, and the vertical rod 2504 adapted to penetrate into the circumferential cutting base 250, a linkage shaft 270 movably installed in a bushing and horizontally positioned, an annular blade 260 fixedly installed at the outer end of the linkage shaft 270, an energy storage housing 2501 installed on the base 2503, and a transmission component 2502 fixedly installed inside the energy storage housing 2501.

[0041] The bottom port of the ring 230 is flush with the bottom port of the cap bottom protector 130;

[0042] A bushing is fixedly installed on the top of the base 2503;

[0043] A deflection gear is fixedly installed at the inner end of the linkage shaft 270;

[0044] The transmission component 2502 consists of a motor and gears.

[0045] After the brim correction assembly 100 is fixed on the workbench, the top cap protector 150 is stretched by adjusting the pre-tightening stud 1106 for knitted yarns of different materials until the length of the top cap protector 150 and the bottom cap protector 130 increases. At this time, the stretched top cap protector 150 and bottom cap protector 130 can provide a fitting carrier for knitted hats with greater elasticity. Conversely, as the length of the top cap protector 150 and bottom cap protector 130 decreases, the top cap protector 150 and bottom cap protector 130 in this state can provide an expansion carrier for knitted hats with less elasticity.

[0046] When the brim of the knitted hat is stretched outward along the curved end of the bottom of the cap protector 130 and pressed tightly by the ring 230, the brim will overflow due to the forced compression. If there are any rough edges on the brim, the rough edges under pressure will be exposed directly above the brim support ring 140. The base 2503, linkage shaft 270, and annular blade 260, pushed down by the pressure rod 240, can precisely cut the overflowing rough edges, thus preventing significant damage to the cut edge due to brim wrinkles. Example 2

[0047] Combination Figures 2 to 5As shown, based on Embodiment 1, the hat brim correction assembly 100 also includes a base 110 fixedly installed at the bottom end of the support rod 1101;

[0048] The outer wall of the support rod 1101 is provided with an annular groove;

[0049] The thickness of the brim support ring 140 is half the thickness of the bottom port of the cap bottom protector 130.

[0050] Preferably, the base 110 is pre-fixed to the working platform using bolts, at which time the base 110 will provide a sufficiently stable support platform for the support rod 1101;

[0051] Specifically, by controlling the pre-tightening stud 1106 to fix the extended inner support rod 160, the extended lengths of the top cap protector 150 and the bottom cap protector 130 can be effectively selected. The stretched top cap protector 150 and bottom cap protector 130 can provide the maximum expansion platform for knitted hats with different elasticities, so as to achieve maximum tension for knitted hats with different elasticities.

[0052] The support leg 220 has a pressure rod 240 and a first spring 2202 fixedly connected between the base 2503 and the support leg 220.

[0053] The pressure rod 240 is adapted to pass through the first spring 2202, and the threaded section at the bottom of the first spring 2202 is installed in the base 2503;

[0054] The cap edge circumferential cutting assembly 200 also includes two housings 280, which are fixedly mounted on the outside of the bushing.

[0055] Preferably, both housings 280 are fixed to the bushing by bolts, and the continuous downward pressure of the two housings 280 on the bottom end will bear pressure on the top of the cap bottom guard 130. At this time, the two housings 280 will provide anti-derailment support for the annular blade 260, ensuring that the annular blade 260 will not be obstructed by the eaves support ring 140 during rotation.

[0056] The working principle and usage process of this utility model are as follows: The base 110 is fixedly installed on the workbench with bolts in advance. Then, the pre-tightening stud 1106 is reversed and the top cap protector 150 and the inner support rod 160 are stretched upward until the length of the top cap protector 150 and the bottom cap protector 130 increases. Then, the pre-tightening stud 1106 is rotated forward.

[0057] Next, the knitted cap is placed over the top protector 150 and the bottom protector 130, and the brim of the knitted cap is stretched outward along the arc-shaped end face of the bottom of the bottom protector 130. At the same time, the support leg 220 is quickly pressed down along the slide on the inner side of the outer frame 2101 until the loop 230 is quickly pre-installed along the outside of the top protector 150 and the bottom protector 130. As the loop 230 descends to the arc-shaped end face of the bottom of the bottom protector 130, the brim part that has been stretched outward can be pre-pressed by applying downward pressure to the loop 230.

[0058] Then the user needs to control the pressure rod 240 and push it down. The base 2503, linkage shaft 270 and annular blade 260, which are pressed down, will quickly move towards the top of the brim support ring 140 until the bottom ports of the other two outer shells 280 are pressed against the top of the cap bottom end protector 130. At this time, the bottom edge of the annular blade 260 is matched with the top of the brim support ring 140. At this time, the wool that overflows from the brim due to the pressure of the ring 230 and the bottom arc end face of the cap bottom end protector 130 will be exposed directly above the brim support ring 140. As the annular blade 260 rotates along the circumference of the top of the brim support ring 140, the linkage shaft 270 and the annular blade 260 driven by the transmission component 2502 will effectively cut the overflow of the brim.

[0059] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
