Description

Technical Field

[0001] The present application relates to crochet machine technology, and in particular to a three-dimensional crochet modification component for a crochet machine and a crochet machine equipped with the three-dimensional crochet modification component. Background Art

[0002] Prior art crochet machine (see Figure 1 and Figure 2 ) includes a needle bed and a warp bar arranged horizontally, and a first weft bar and a second weft bar are arranged one after the other above the needle bed. When working, a hook needle is installed in the needle groove on the needle bed, a curved needle is installed in the needle groove on the warp bar, and a needle tube is installed in the needle groove on the first weft bar and the second weft bar. The needle bed reciprocates back and forth to make the warp threaded on the curved needle into a loop, and the first weft bar and the second weft bar reciprocate in the left and right directions. The second weft is stacked on the first weft and fixed by the looped warp. The fabric crocheted by the prior art crochet machine is flat and is often used to produce narrow warp knitted fabrics such as lace bands and elastic bands.

[0003] Wire loop foot pads are a type of foot pad that has become popular in recent years. They are made of a surface fabric and a base pad (the base pad is usually made of PVC or TPR) that are compounded through a hot melt or scraping process. In the prior art, the surface fabric of the wire loop foot pad is obtained by planting PVC cored wire onto the base fabric using a loop pile machine. With the popularity of wire loop foot pads, more and more manufacturers have joined the ranks of wire loop foot pad manufacturing, and the products are highly homogenized. The market competition pressure continues to increase, product prices are gradually falling, and the profit margins of manufacturers are very limited. Some even face losses and bankruptcy. Therefore, it is necessary to reduce the production cost of foot pads and / or avoid product homogeneity competition through the development of new production technologies. Summary of the invention

[0004] In view of the above problems existing in the prior art, the present application provides a three-dimensional crochet modification component for a crochet machine and a crochet machine equipped with the modification component. The three-dimensional crochet modification component for a crochet machine of the present application has a simple structure and low investment cost, which is conducive to industrial promotion; the crochet machine equipped with the modification component can crochet a three-dimensional crochet fabric, and the three-dimensional crochet fabric is used as the surface material to manufacture foot pads, which can reduce the manufacturing cost compared with traditional wire loop foot pads, and the foot pads produced have a novel and comfortable visual experience, avoiding product homogeneity competition.

[0005] For the modified components, the technical solution of this application is as follows:

[0006] A three-dimensional crochet modification component for a crochet machine, the three-dimensional crochet modification component for a crochet machine is used to be installed on a crochet machine body to modify the crochet machine so that the crochet machine can crochet three-dimensional fabrics; the crochet machine body includes a needle bed and a warp comb arranged horizontally, and a first weft comb and a second weft comb are arranged one after the other above the needle bed; the three-dimensional crochet modification component for a crochet machine includes a three-dimensional forming tooth plate for installation between the first weft comb and the second weft comb; a group of needle-passing notches are provided on the lower edge of the three-dimensional forming tooth plate, thereby forming a second weft three-dimensional forming tooth between two adjacent needle-passing notches; the needle-passing notches correspond to the needle grooves on the needle bed, so that the crochet needle installed on the needle groove can pass through when making a back-and-forth reciprocating motion.

[0007] The three-dimensional crochet modification component for the crochet machine provided by this solution has a simple structure and low investment cost, which is conducive to industrial promotion; the three-dimensional crochet modification component is installed on the crochet machine to produce new crochet fabrics in three-dimensional form.

[0008] As an optimization, the aforementioned three-dimensional crochet modification assembly for the crochet machine further includes a connector for fixing the three-dimensional forming tooth plate to the crochet machine body. After the connector is provided, the three-dimensional forming tooth plate is easily installed on the crochet machine.

[0009] As an optimization, in the aforementioned three-dimensional crochet modification assembly for the crochet machine, both the front and rear sides of the end of the second weft three-dimensional forming tooth are processed with chamfers or fillets. Processing the chamfers or fillets on both the front and rear sides of the end of the second weft three-dimensional forming tooth is conducive to the second weft thread being detached from the second weft three-dimensional forming tooth after being looped.

[0010] As an optimization, in the aforementioned three-dimensional crochet modification assembly for a crochet machine, both the front and rear ends of the second weft three-dimensional forming teeth are processed with rounded corners. Compared with setting a chamfer, the rounded corner design makes it easier for the second weft to detach from the second weft three-dimensional forming teeth after forming a loop.

[0011] As an optimization, in the aforementioned three-dimensional crochet modification assembly for a crochet machine, the rear side of the second three-dimensional weft forming tooth is provided with an inclined guide surface connected with the end fillet. The provision of the inclined guide surface is also conducive to the second weft thread being detached from the second three-dimensional weft forming tooth after looping.

[0012] As an optimization, in the aforementioned three-dimensional crochet modification assembly for a crochet machine, the inclined guide surface is a plane, and the inclination angle θ formed by the plane and the horizontal line is in the range of 50°-80°. A plane is easier to process than an arc surface. Tests show that when the inclination angle θ formed by the plane-shaped inclined guide surface and the horizontal line is in the range of 50°-80°, the second weft thread can be separated from the second weft thread three-dimensional forming tooth more smoothly after looping.

[0013] For the crochet machine, the technical solution of this application is as follows:

[0014] A crochet machine equipped with a three-dimensional crochet modification component comprises a crochet machine body; the crochet machine body comprises a needle bed and a warp comb arranged horizontally, a first weft comb bar and a second weft comb bar are arranged one after the other above the needle bed; and also comprises a three-dimensional crochet modification component; the three-dimensional crochet modification component comprises a three-dimensional forming tooth plate arranged between the first weft comb bar and the second weft comb bar; a group of needle passing slots corresponding to the needle grooves on the needle bed are arranged on the lower edge of the three-dimensional forming tooth plate, so that the crochet needle installed on the needle groove can pass through when making a back-and-forth reciprocating motion, thereby forming a second weft three-dimensional forming tooth between two adjacent needle passing slots.

[0015] Compared with the prior art, the crochet machine equipped with a three-dimensional crochet modification component of the present application can produce three-dimensional crochet fabrics in a three-dimensional form. The three-dimensional crochet fabric can be used as the surface material of the foot pad. Its manufacturing cost is lower than that of the surface material used on the traditional wire loop foot pad, so that the production cost of the foot pad can be reduced compared with the traditional wire loop foot pad. In the three-dimensional crochet fabric, the second weft thread is blocked by the second weft thread three-dimensional forming teeth, and will arch to form a regularly arranged arched structure, which can not only provide customers with a novel and comfortable visual experience and avoid product homogeneity competition, but also the small particles of garbage dropped on the foot pad can be easily shaken off, which is convenient for cleaning and has good practicality.

[0016] As an optimization, in the aforementioned crochet machine equipped with a three-dimensional crochet modification component, the rear side of the second weft three-dimensional forming tooth is provided with an inclined guide surface extending to the end of the second weft three-dimensional forming tooth. By providing the inclined guide surface, it is also convenient for the second weft to detach from the second weft three-dimensional forming tooth after looping.

[0017] As an optimization, in the aforementioned crochet machine equipped with a three-dimensional crochet modification component, the inclined guide surface is a plane, and the inclination angle θ formed by the plane and the horizontal line is 50°-80°. A plane is easier to process than an arc surface. Tests show that when the inclination angle θ formed by the plane-shaped inclined guide surface and the horizontal line is in the range of 50°-80°, the second weft thread can be separated from the second weft thread three-dimensional forming tooth more smoothly after looping.

[0018] As an optimization, in the aforementioned crochet machine equipped with a three-dimensional crochet modification component, the upper end of the inclined guide surface is higher than the needle groove on the needle bed in the vertical direction. As a result, the second weft is arched on the inclined guide surface to form an arched structure, and after the warp is fixed, it directly starts to slide down from the inclined guide surface, which also plays a role in making the second weft smoothly detach from the second weft three-dimensional forming teeth after the second weft is looped.

DETAILED DESCRIPTION

[0033] The present application is further described below in conjunction with the accompanying drawings and specific implementation methods (including examples), but they are not intended to limit the present application. In the following examples, the contents not described in detail are all common technical knowledge in the art.

[0034] Example:

[0035] See also Figure 1-13 The crochet machine equipped with the modification component of this embodiment includes a crochet machine body; the crochet machine body includes a needle bed 1 and a warp comb 2 arranged horizontally, and a first weft comb 3 and a second weft comb 4 are arranged one after the other above the needle bed 1; it also includes a three-dimensional crochet modification component; the three-dimensional crochet modification component includes a three-dimensional forming tooth plate 5 arranged between the first weft comb 3 and the second weft comb 4 (the three-dimensional forming tooth plate 5 is fixed to the crochet machine body through a connecting piece); the lower edge of the three-dimensional forming tooth plate 5 is provided with a group of needle slots 501 corresponding to the needle grooves on the needle bed 1, so that the crochet needle 9 installed on the needle groove can pass through when making a back and forth reciprocating motion, thereby forming a second weft three-dimensional forming tooth 502 between two adjacent needle slots 501.

[0036] In this embodiment, both the front and rear ends of the second weft three-dimensional forming teeth 502 are processed with rounded corners.

[0037] In this embodiment, the rear side of the second weft three-dimensional forming tooth 502 is provided with an inclined guide surface 5021 connected with the end fillet.

[0038] In this embodiment, the inclined guide surface 5021 is a plane, and the inclination angle θ formed by the inclined guide surface 5021 and the horizontal line is 60°.

[0039] In this embodiment, the upper end of the inclined guide surface 5021 is vertically higher than the needle groove on the needle bed 1 .

[0040] The following is a further explanation of this application in combination with the working principle and the fabric produced:

[0041] During production, like the crochet machine in the prior art, a hook needle 9 needs to be installed in the needle groove of the needle bed 1, a bent needle 10 needs to be installed in the needle groove of the warp bar 2, a needle tube 11 needs to be installed in the needle grooves of the first weft bar 3 and the second weft bar 4, and the warp 6 needs to be passed through the needle head of the bent needle 10, and the first weft bar 7 and the second weft bar 8 need to be passed through the tube body of the needle tube 11. After the machine is turned on, the needle bed 1 reciprocates in the front and back directions, the first weft bar 2 and the second weft bar 3 reciprocate in the left and right directions (the first weft bar 2 and the second weft bar 3 reciprocate up and down while reciprocating left and right), and the warp 6 is knotted into a loop under the action of the hook needle 9, and the first weft bar 7 and the second weft bar 8 are fixed. In the present application, since a three-dimensional forming tooth plate 5 of a specific structure is provided between the first weft comb bar 2 and the second weft comb bar 3, the second weft 8 will be arched to form an arched structure during the crocheting process due to the blocking effect of the second weft three-dimensional forming teeth 502 on the three-dimensional forming tooth plate 5, thereby producing a fabric (see Fig.12 ) has a three-dimensional visual effect.

[0042] As a specific application example, the second weft 8 is made of PVC core-spun wire. Since the PVC core-spun wire has good plasticity, the fabric produced is not easy to deform and can maintain a three-dimensional state for a long time. The fabric and the base pad 13 are composited by hot melt (the composite structure is as shown in FIG. Fig.13 As shown in the figure), the foot pad is cut into a specific shape to obtain a foot pad product. Since the surface fabric of the foot pad has no base fabric substrate, it is directly crocheted using the crochet machine of the present application (the first weft thread plays the role of substrate in the fabric), the material cost is low, and in the fabric crocheted by the crochet machine of the present application, the arched structure formed by the arching of the second weft thread has a regular arrangement (see Fig.12 ), not only the visual effect is novel and unique, but also the particles of garbage that fall on it are easy to shake off and easy to take care of.

[0043] The above general description of the invention involved in this application and the description of its specific implementation methods should not be understood as limiting the technical solutions of the invention. Based on the disclosure of this application, those skilled in the art can add, reduce or combine the disclosed technical features in the above general description and / or specific implementation methods (including examples) without violating the constituent elements of the invention involved, to form other technical solutions within the scope of protection of this application.
