Description

Technical Field

[0001] This application relates to the field of fabric preparation technology, and in particular to an apparatus for preparing high-strength, non-deformable polyester knitted fabrics. Background Technology

[0002] Polyester knitted fabric is a type of fabric made primarily of polyester using knitting techniques. Due to its excellent comfort and durability, polyester knitted fabric is widely used in clothing, home textiles, and other fields.

[0003] In the traditional production process of polyester knitted fabrics, the strength and deformation resistance of the fabric are often difficult to achieve the ideal state, which affects the service life and appearance of the product. At present, the industry usually improves the strength and stability of polyester knitted fabrics through chemical or physical methods, such as using special coating treatments or heat setting processes to improve the physical properties of the fabric. However, these methods often require additional materials and processes, which not only increases costs but may also have a negative impact on the environment. Existing polyester knitted fabric reinforcement technologies often involve complex processes and additional materials, which increases production costs and may also affect the natural characteristics and hand feel of the fabric. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a device for preparing high-strength, non-deformable polyester knitted fabric, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: An apparatus for preparing high-strength, non-deformable polyester knitted fabric, comprising an operating table, a knitting machine fixedly mounted on the top of the operating table, needles slidably connected to the inner wall of the knitting machine, a bobbin on the top of the operating table, a support plate fixedly mounted on the outer side of the operating table, an infrared heating tube on the inner wall of the support plate, a fixed plate fixedly mounted on the outer side of the support plate, a motor fixedly mounted on the outer side of the fixed plate, a winding roller fixedly connected to the output shaft of the motor, a controller fixedly mounted on the top of the operating table, a connecting plate fixedly mounted on the side of the operating table away from the support plate, a connecting frame fixedly connected to the bottom of the connecting plate, a microwave heating box fixedly mounted on the top of the connecting frame, a slot opened in the inner wall of the microwave heating box, a cylinder fixedly mounted on the top of the microwave heating box, a pressure plate fixedly connected to the output end of the cylinder, two side plates symmetrically fixedly mounted on the outer side of the microwave heating box, a plurality of conduction rollers fixedly mounted on the inner wall of the side plates, and cooling pipes fixedly mounted on the inner wall of the conduction rollers.

[0006] In a preferred embodiment, a fixing plate is fixedly mounted on the outer side of each of the two side plates, and a take-up roller is rotatably connected to the inner wall of the two fixing plates. A turntable is fixedly mounted on the outer side of the take-up roller.

[0007] By adopting the above technical solution, the fabric can be pulled by wrapping one side of the fabric around the outer edge of the take-up roller and pressing the other side against the inner wall of the groove, thereby ensuring that the fabric will not easily deform or wrinkle when it is cooled by the outer edge of the conduction roller.

[0008] In a preferred embodiment, a positioning strip is fixedly mounted on the outer side of the support plate, and the side of the winding roller away from the fixed plate is rotatably connected to the inner wall of the positioning strip.

[0009] By adopting the above technical solution, the end of the winding roller away from the fixed plate can be positioned, thereby ensuring the stability of the winding roller during rotation.

[0010] In a preferred embodiment, a support frame is fixedly mounted on the top of the support plate, and an infrared heating tube is fixedly mounted on the bottom of the support frame.

[0011] By adopting the above technical solution, the fabric can be placed in the middle of two infrared heating tubes to heat the fabric, thereby improving its dimensional stability. In addition, compared with traditional hot air heating, infrared heating tubes can heat the fabric more evenly and faster, which helps to improve production efficiency.

[0012] In a preferred embodiment, the side of the connecting plate away from the operating table is also fixedly equipped with a fixing plate, a motor, a winding roller, and a positioning strip.

[0013] By adopting the above technical solution, one side of the knitted fabric can be wound to the outer edge of the winding roller, and in conjunction with another winding roller, the fabric can be stretched, thereby increasing the density of the fabric.

[0014] In a preferred embodiment, the controller, motor, and infrared heating tube are all electrically connected, and the controller, microwave heating box, cylinder, and cooling pipe are all electrically connected. The inner cavity of the conduction roller is provided with coolant.

[0015] By adopting the above technical solutions, the operation of electronic components can be intelligently and precisely controlled, and the operation time can be preset to achieve intelligent automatic operation.

[0016] In a preferred embodiment, the microwave heating box has a receiving groove at its inner top, and the pressure plate is disposed on the inner wall of the receiving groove.

[0017] By adopting the above technical solution, the pressure plate can be stored in the inner wall of the receiving groove when the fabric does not need to be squeezed, thereby realizing the movement of the fabric.

[0018] The beneficial effects of this application are:

[0019] 1. This equipment for preparing high-strength, non-deformable polyester knitted fabrics increases the transverse and longitudinal tensile strength of the fabric without increasing its thickness by adding cross-knitting to the basic knitting structure. Furthermore, the grooves allow for pre-treatment of the fabric, making its fiber structure more porous and facilitating subsequent heat setting. This significantly improves the strength and non-deformability of the polyester knitted fabric, while simplifying the production process and reducing production costs. Through equipment improvement and process optimization, both fabric performance enhancement and production efficiency are simultaneously increased.

[0020] 2. This equipment for preparing high-strength, non-deformable polyester knitted fabric cools the fabric by winding it around the outer edges of several guide rollers. Then, the two ends of the knitted fabric are wound around the outer edges of two winding rollers to stretch the fabric, thereby increasing its density. At the same time, infrared heating tubes can be used to heat the fabric to improve its dimensional stability. Compared with traditional hot air heating, infrared heating tubes can heat the fabric more evenly and faster, which helps to improve production efficiency. Attached Figure Description

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0027] Reference Figure 1-4 An apparatus for preparing high-strength, non-deformable polyester knitted fabric includes an operating table 1, a knitting machine 2 fixedly mounted on the top of the operating table 1, needles 4 slidably connected to the inner wall of the knitting machine 2, a yarn spool 3 on the top of the operating table 1, a support plate 5 fixedly mounted on the outer side of the operating table 1, an infrared heating tube 6 on the inner wall of the support plate 5, a fixed plate 8 fixedly mounted on the outer side of the support plate 5, a motor 9 fixedly mounted on the outer side of the fixed plate 8, a winding roller 10 fixedly connected to the output shaft of the motor 9, and a controller 11 fixedly mounted on the top of the operating table 1. A connecting plate 12 is fixedly mounted on the side of the worktable 1 away from the support plate 5. A connecting frame 13 is fixedly connected to the bottom of the connecting plate 12. A microwave heating box 14 is fixedly mounted on the top of the connecting frame 13. A slot 15 is opened on the inner wall of the microwave heating box 14. A cylinder 16 is fixedly mounted on the top of the microwave heating box 14. A pressure plate 17 is fixedly connected to the output end of the cylinder 16. Two side plates 18 are symmetrically fixedly mounted on the outer side of the microwave heating box 14. Several conduction rollers 19 are fixedly mounted on the inner wall of the side plates 18. Cooling pipes 20 are fixedly mounted on the inner wall of the conduction rollers 19.

[0028] See Figure 3 and Figure 4 The outer sides of both side plates 18 are fixedly fitted with fixing plates 21, and the inner walls of the two fixing plates 21 are rotatably connected with take-up rollers 22. The outer side of the take-up rollers 22 is fixedly fitted with turntables 23, so that when one side of the fabric is rolled around to the outer edge of the take-up rollers 22 and the other side is squeezed to the inner wall of the slot 15, the fabric can be pulled, thereby ensuring that the fabric will not easily deform or wrinkle when it passes through the outer edge of the conduction rollers 19 for cooling.

[0029] See Figure 1 and Figure 2 A positioning strip is fixedly mounted on the outer side of the support plate 5. The side of the winding roller 10 away from the fixed plate 8 is rotatably connected to the inner wall of the positioning strip, so that the end of the winding roller 10 away from the fixed plate 8 can be positioned, thereby ensuring the stability of the winding roller 10 when it rotates.

[0030] See Figure 1 The top of the support plate 5 is fixedly equipped with a support frame 7, and the bottom of the support frame 7 is also fixedly equipped with an infrared heating tube 6, so that the fabric can be placed in the middle of the two infrared heating tubes 6 to heat the fabric and improve its dimensional stability. In addition, compared with traditional hot air heating, infrared heating tube 6 can heat the fabric more evenly and the heating speed is faster, which helps to improve production efficiency.

[0031] See Figure 2 The connecting plate 12 is also fixedly equipped with a fixed plate 8, a motor 9, a winding roller 10 and a positioning strip on the side away from the operating table 1, so that one side of the knitted fabric can be wound to the outer edge of the winding roller 10, and in conjunction with another winding roller 10, it can stretch the fabric, thereby increasing the density of the fabric.

[0032] See Figure 1 - Figure 4 The controller 11, motor 9 and infrared heating tube 6 are all electrically connected. The controller 11, microwave heating box 14, cylinder 16 and cooling pipe 20 are all electrically connected. The inner cavity of the transmission roller 19 is equipped with coolant, which enables intelligent and precise control of the operation of electronic components and allows the preset operation time to achieve intelligent automatic operation.

[0033] See Figure 4 The microwave heating box 14 has a receiving groove at its inner top, and a pressure plate 17 is set on the inner wall of the receiving groove, so that the pressure plate 17 can be stored in the inner wall of the receiving groove when the fabric does not need to be squeezed, thereby realizing the movement of the fabric.

[0034] Working principle: When using this device, the yarn wound around the outer edge of the spool 3 is first passed through the threading hole on the inner wall of the needle 4, and then the knitting fabric operation can be carried out. By adding a cross-knitting part to the basic knitting structure of the fabric, the tensile strength in the transverse and longitudinal directions can be improved without increasing the fabric thickness. At the same time, the fabric can be threaded into the inner cavity of the slot 15 to pre-treat the fabric, making its fiber structure more fluffy, which is conducive to the subsequent heat setting treatment. The pre-treated end of the fabric is wound to the outer edge of the take-up roller 22, thereby driving the cylinder. The pressure plate 17 moves downwards, which can squeeze and shape the fabric and roll the fabric around to the outer edge of several guide rollers 19, thereby cooling the fabric. Then, the two ends of the knitted fabric can be rolled around to the outer edge of two winding rollers 10, thereby stretching the fabric and increasing its density. At the same time, the infrared heating tube 6 can be used to heat the fabric to improve its dimensional stability. Compared with traditional hot air heating, the infrared heating tube 6 can heat the fabric more evenly and faster, which helps to improve production efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and the inventive concept of this application, should be included within the scope of protection of this application.
