Description

Technical Field

[0001] The invention belongs to the technical field of crochet machines, and in particular relates to a head for a crochet machine. Background Art

[0002] A crochet machine is a type of mechanical equipment specifically designed for the efficient production of knitted fabrics. It uses the crochet needles inside the machine head to quickly and accurately weave yarn into various types of fabrics, such as sweaters, socks, hats, and other textiles. It is widely used in the garment manufacturing and home textile industries, and can produce a variety of products from simple structures to complex patterns.

[0003] After searching, it was found that a crochet machine head device was disclosed in the Chinese patent with the authorization announcement number "CN112813578B", which includes a box body and a yarn swinging mechanism and a yarn hooking and weaving mechanism placed on the box body, as well as a power transmission mechanism that provides power to the yarn swinging mechanism and the yarn hooking and weaving mechanism. The power transmission mechanism includes a power drive shaft, a swing transmission assembly and a lifting transmission assembly. The power drive shaft drives the yarn swinging mechanism to move through the swing transmission assembly; the power drive shaft drives the yarn hooking and weaving mechanism to move through the lifting transmission assembly.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1 See also Figures 1-11 , the present invention provides the following technical solutions: A head for a crochet machine, comprising: The head sleeve 1, the upper end of the head sleeve 1 is rotatably connected to the crochet seat, and the crochet seat has a plurality of yarn guide hooks 28 arranged in a circular array; The wire outlet hole 2 is opened at the upper end of the head sleeve 1; The wire clamping cavity 3 is provided in the handpiece sleeve 1 and communicates with the wire outlet hole 2; A guide tube 7 is slidably connected to the outlet hole 2; The sealing slider 8 is fixedly connected to the lower end of the guide tube 7 and slides in the wire clamping cavity 3; A hydraulic tank 5 is provided in the handpiece sleeve 1 and is filled with water; Lead assembly, the lead assembly is provided with two groups, each group of lead assembly includes a blocking groove 4, a boost hole 6, a blocking block 9 and a blocking rod 10, the blocking groove 4 is opened on the circumferential inner wall of the wire clamping cavity 3, the boost hole 6 is opened on the upper inner wall of the blocking groove 4 and is connected to the hydraulic groove 5, the blocking block 9 is fixedly connected to the lower end of the sealing slider 8, and the blocking rod 10 is fixedly connected to the upper end of the blocking block 9 and slides in the boost hole 6; The booster assembly is provided with two groups, and both groups of booster assemblies are provided in the head sleeve 1 to increase the pressure in the hydraulic tank 5.

[0023] In a specific embodiment of the present invention, the crochet seat at the top of the head sleeve 1 is used to form lines during weaving to complete the weaving process, and the lead assembly in the head sleeve 1 is used to guide the woven yarn out during weaving. Then water is provided in the hydraulic tank 5, and the sealing rod 10 is provided in the boosting hole 6 to close the channel boosting hole 6 between the hydraulic tank 5 and the wire clamping cavity 3. When the sealing slider 8 is located at the top of the wire clamping cavity 3, the guide tube 7 guides the woven yarn to extend, and the height of the sealing slider 8 is controlled by the hydraulic pressure in the hydraulic tank 5. Since the distance between the liquid molecules is already quite close, the interaction force between them is strong, so that the water in the hydraulic tank 5 has a relatively fixed volume. By pressing the pressing block 13 to reduce the space in the hydraulic tank 5, the hydraulic pressure in the hydraulic tank 5 increases and squeezes the sealing rod 10 in the boosting hole 6 to slide downward.

[0024] For details, please refer to Figures 1-11 Each boosting assembly includes a boosting groove 11, a spring plate 12, a pressing block 13, a spring groove 14 and a boosting spring 15. The boosting groove 11 is opened at one side end of the head sleeve 1, the spring plate 12 is fixedly connected to one side inner wall of the hydraulic groove 5, the pressing block 13 is slidably connected in the boosting groove 11, the spring groove 14 is opened at one side end of the pressing block 13, and the boosting spring 15 is fixedly connected to one side end of the spring plate 12 and one side inner wall of the spring groove 14.

[0025] In this embodiment: the pressing block 13 slides in the boosting groove 11 to increase the hydraulic pressure in the hydraulic groove 5, and the boosting spring 15 is fixed between the spring plate 12 and the pressing block 13. When boosting is required, the operator presses the pressing block 13 from both sides and contracts the boosting spring 15. The pressing block 13 squeezes into the hydraulic groove 5 to reduce the space in the hydraulic groove 5, and then the hydraulic pressure in the boosted hydraulic groove 5 pushes the position of the sealing slider 8 downward. When the operator releases the pressing block 13, the boosting spring 15 that was squeezed and contracted before rebounds and pushes the pressing block 13 back to its original position. At this time, the hydraulic pressure in the hydraulic groove 5 is reduced, and the sealing rod 10 is pulled back to its original position, and the sealing slider 8 is pulled upward to reset.

[0026] For details, please refer to Figures 1-11 A clamping groove 16 is provided at the lower end of the sealing slider 8, and two groups of clamping components are provided in the sealing slider 8, each group of clamping components includes a limiting slide 17, a closed clamping block 18, a limiting slider 19, a closing spring 20 and a boost channel 32, the limiting slide 17 is provided on the side inner wall of the clamping groove 16, the limiting slider 19 is slidably connected in the limiting slide 17, the closed clamping block 18 is fixedly connected to one side end of the limiting slider 19, the closing spring 20 is fixedly connected to one side end of the closing clamping block 18 and one side inner wall of the clamping groove 16, and the boost channel 32 is provided in the sealing rod 10 and the sealing slider 8 and is connected to the hollow part of the closing spring 20.

[0027] When the two pressing blocks 13 are not pressed, the two closed clamping blocks 18 do not contact each other. At this time, the lower end opening of the guide tube 7 is connected to the wire clamping cavity 3, so that the woven yarn head in the guide tube 7 can enter the wire clamping cavity 3. When the two pressing blocks 13 are pressed, the pressure in the hydraulic groove 5 will increase, and the closing spring 20 is a hollow spring, which is connected to the space in the hydraulic groove 5 through the boost channel 32. At this time, the internal pressure of the closing spring 20 increases, which will cause the closing spring 20 to become longer, so that the two closing springs 20 push the closed clamping blocks 18 to close each other to close the lower end of the guide tube 7, and clamp the yarn downward and straighten it. When the pressing block 13 is released, the pressure decreases, causing the length of the two closing springs 20 to shrink, so that the two closed clamping blocks 18 are separated. At this time, the sealing slider 8 will also rise. Repeatedly pressing the pressing block 13 can guide the woven yarn to escape from the device.

[0028] For details, please refer to Figures 1-11 The lower inner wall of the wire clamping cavity 3 is fixedly connected to two extrusion blocks 30, and the upper ends of the two extrusion blocks 30 and the lower ends of the two closed clamping blocks 18 are both inclined surfaces.

[0029] In this embodiment: the contact surfaces of the extrusion block 30 and the closed clamping block 18 are both inclined surfaces. When the sealing slider 8 slides downward to the bottom of the wire clamping cavity 3, the inclined surface of the closed clamping block 18 contacts the extrusion block 30 and squeezes the closing spring 20 to contract, to ensure that when the sealing slider 8 rises, the two closed clamping blocks 18 are in an open state, so that the woven yarn continues to fall into the rolling lead-out area of the roller body 33.

[0030] For details, please refer to Figures 1-11 The inner circumferential wall of the guide tube 7 is provided with a plurality of vent holes 22 , and the inner side wall of the clamping groove 16 is provided with a guide angle 21 .

[0031] In this embodiment: when the sealing slider 8 drives the guide tube 7 to slide in the wire outlet hole 2, air pressure fluctuations will be generated in the guide tube due to space changes. The vent 22 can eliminate the air pressure difference by circulating with the outside air, thereby avoiding the air pressure hindering the smooth outlet of the yarn. The guide angle 21 is a trumpet-shaped expansion that gradually expands downward, which provides more ample room for movement for the opening and closing action of the closed clamping block 18, making the expansion and contraction process of the closed spring 20 more stable. The closed spring 20 is a hollow spring. When the pressure in the internal space of the closed spring 20 increases, the closed spring 20 will become longer, and vice versa.

[0032] For details, please refer to Figures 1-11 Two roller bodies 33 are rotatably connected below the yarn outlet hole 31, and the rotation of the roller bodies 33 is controlled by an external motor.

[0033] In this embodiment, the two roller bodies 33 rotate in opposite directions so that the woven yarn rolls out from between the two roller bodies 33 .

[0034] For details, please refer to Figures 1-11 The upper end of the head sleeve 1 is fixedly connected to a support plate 26 , a yarn guide hole 27 is opened at the upper end of the support plate 26 , and a side yarn guide hole 29 is fixedly connected to one side end of the support plate 26 .

[0035] In this embodiment: the yarn guide hole 27 guides the yarn smoothly through the machine, ensuring that the yarn can accurately reach the yarn guide hook 28 and prevent it from being entangled or knotted during transmission. The lateral yarn guide hole 29 minimizes the friction between the yarn and the yarn guide hook 28, reduces the risk of yarn wear, extends the service life of the yarn, and maintains the quality of the yarn.

[0036] For details, please refer to Figures 1-11 A yarn outlet hole 31 is provided at the lower end of the head sleeve 1, and the lower inner wall of the yarn outlet hole 31 is arc-shaped.

[0037] In this embodiment, the yarn outlet hole 31 is the outlet position of the lower end of the head sleeve 1, and the woven yarn is discharged through this hole.

[0038] For details, please refer to Figures 1-11 The length of the blocking rod 10 is greater than the distance from the lower inner wall of the wire clamping cavity 3 to the lower end of the sealing slider 8.

[0039] In this embodiment, the length of the blocking rod 10 is greater than the distance from the lower inner wall of the clamping cavity 3 to the lower end of the sealing slider 8. When the sealing slider 8 slides to the bottom of the clamping cavity 3, the blocking rod 10 is still located in the pressurizing hole 6 to seal the water in the hydraulic tank 5. The working principle and use process of the present invention are as follows: the top of the machine head sleeve 1 is used to form coils in weaving or embroidery work to complete the weaving process, and the wire guide device in the machine head sleeve 1 is used to guide the woven yarn out in each weaving work, and then water is provided in the hydraulic tank 5, and the blocking rod 10 is provided in the boost hole 6 to close the channel boost hole 6 between the hydraulic tank 5 and the wire clamping cavity 3. When the sealing slider 8 is located at the top of the wire clamping cavity 3, the guide tube 7 guides the woven yarn to extend, and the height of the sealing slider 8 is controlled by the hydraulic pressure in the hydraulic tank 5. Since the distance between the liquid molecules is already quite close, the interaction force between them is relatively strong, so that the water in the hydraulic tank 5 has a relatively fixed volume. By pressing the pressing block 13 to reduce the space in the hydraulic tank 5, the hydraulic pressure in the hydraulic tank 5 increases and squeezes the blocking rod 10 in the boost hole 6 to slide downward. When When the two pressing blocks 13 are pressed, the pressure in the hydraulic groove 5 will increase, and the closing spring 20 is a hollow spring, which is connected to the space in the hydraulic groove 5 through the boosting channel 32. At this time, the internal pressure of the closing spring 20 increases, which will cause the closing spring 20 to lengthen, so that the two closing springs 20 push the closing clamping blocks 18 to close each other to close the lower end of the guide tube 7, and will clamp the yarn and straighten it downward. When the pressing block 13 is released, the pressure decreases, causing the length of the two closing springs 20 to shrink, so that the two closing clamping blocks 18 are separated. At this time, the sealing slider 8 will also rise. Repeatedly pressing the pressing block 13 can guide the woven yarn to come out of the device. Two roller bodies 33 are rotatably connected below the yarn outlet hole 31, and the roller bodies 33 are controlled to rotate by an external motor. The two roller bodies 33 rotate in opposite directions so that the thread ends pass through the middle of the two roller bodies 33.

[0040] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
