Description

A folding mechanism and a non-woven fabric folding machine Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, specifically to a folding mechanism and a nonwoven fabric folding machine. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is made of polyester fiber, polyester fiber (abbreviated as: PET) material and is made through needle punching process. Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, lightweight, flame-retardant, non-toxic and odorless, inexpensive and recyclable. Currently, before processing non-woven fabric (such as non-woven fabric pressing treatment), it is necessary to fold the non-woven fabric first, which requires the use of non-woven fabric folding machine.

[0003] However, existing folding machines cannot adjust the fold width and length of nonwoven fabrics, which greatly reduces the practicality of the nonwoven fabric folding process.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a folding mechanism and a non-woven fabric folding machine.

[0005] Utility Model Content

[0006] The purpose of this invention is to provide a folding mechanism and a non-woven fabric folding machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a folding mechanism, comprising a folding assembly, the folding assembly comprising a body, guide sleeves, connecting pins, a motor, a gear set, rubber double rollers, and a width adjustment plate. Guide sleeves are symmetrically fixed on both sides of the body, and a connecting pin is fixed in the middle of the rear end of the body. A motor is fixed at one end inside the body, and the output end of the motor is rotatably connected to the gear set, which rotates and drives the corresponding rubber double rollers. A width adjustment plate is slidably installed at the other end inside the body, and the central hole of the width adjustment plate is larger than the diameter of the rubber double rollers.

[0008] Furthermore, the gear set consists of two meshing gears, and the gear set drives opposing rubber rollers to rotate in opposite directions.

[0009] Furthermore, the body is positioned above the base, and the base has protrusions fixed at its four corners.

[0010] Furthermore, guide rods are fixed to the opposing surfaces of the front and rear bosses, and the guide rods slide in conjunction with the guide sleeves.

[0011] Furthermore, a conveyor belt is provided in the middle of the base, and an adjustment component is fixed at the rear end of the base. The adjustment component includes a second motor, a rotating rod, a pin, and a through hole. The output end of the second motor is fixedly connected to the rotating rod, and a pin is inserted laterally at the end of the rotating rod, and a through hole is opened longitudinally at the end of the rotating rod.

[0012] Furthermore, the adjustment assembly also includes an adjustment rod, an end cap, and a connecting rod. The adjustment rod is slidably fitted inside the through hole and is fixed to the rotating rod by a pin. The end cap is fixed to the end of the adjustment rod, and a connecting rod is rotatably connected to the outside of the end cap. The end of the connecting rod is rotatably connected to the machine body by a connecting pin.

[0013] A nonwoven fabric folding machine is provided, which is equipped with the above-mentioned folding mechanism, including a folding frame, a conveyor belt at the front end of the folding frame, an unwinding roller rotatably mounted at the bottom rear end of the folding frame, and a tensioning roller rotatably mounted at the top front end of the folding frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In use, the nonwoven fabric is pulled out by the unwinding roller at the bottom rear end of the folding frame and wound around to the tensioning roller at the top front end, and finally placed between the rubber double rollers. The motor is activated to drive the rubber double rollers to rotate in opposite directions through the gear set. Under the action of friction, the nonwoven fabric is continuously discharged, and at the same time, it also has a certain leveling effect. On the one hand, this application sets a sliding adjustable width adjustment plate at the other end of the machine body to adjust the folding width of the nonwoven fabric.

[0016] 2. In use, the motor's output rod rotates through the adjusting rod to drive the connecting rod, thereby causing the guide sleeves at both ends of the machine body to slide on the guide rods on the opposite surfaces of the front and rear bosses. During the reciprocating sliding of the folding assembly, the non-woven fabric is continuously folded. By changing the extension length of the adjusting rod through the pin, the rotation radius of the lower connecting rod driven by the end of the adjusting rod is adjusted, thereby adjusting the reciprocating stroke length of the folding assembly and adjusting the folding length of the non-woven fabric. After the non-woven fabric has completed the preset number of folds, it is cut and fed by the conveyor belt to complete the production process, resulting in a higher degree of automation.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] [Revised according to Rule 26, August 2021] As shown in Figures 1 to 3, a folding mechanism includes a folding assembly 1. The folding assembly 1 includes a body 101, guide sleeves 102, connecting pins 103, a motor 104, a gear set 105, rubber double rollers 106, and a width adjustment plate 107. Guide sleeves 102 are symmetrically fixed on both sides of the body 101, and a connecting pin 103 is fixed in the middle of the rear end of the body 101. A motor 104 is fixed inside one end of the body 101, and the output end of the motor 104 is rotatably connected to the gear set 105. The gear set 105 rotates and drives the corresponding rubber double rollers 106. The other end of the body 101... A width adjustment plate 107 is slidably installed, and the central hole of the width adjustment plate 107 is larger than the diameter of the rubber double roller 106. The width adjustment plate 107 and the machine body 101 are in a sliding fit relationship, while the width adjustment plate 107 and the rubber double roller 106 are in a clearance fit relationship. A fixed plate is located on one side of the motor 104 for mounting the gear set 105. The distance between the width adjustment plate 107 and the fixed plate corresponds to the folding width of the rubber double roller 106 of the nonwoven fabric. This application adjusts the folding width of the nonwoven fabric by providing a slidably adjustable width adjustment plate 107 at the other end of the machine body 101. The gear set 105 consists of two meshing gears. The machine is composed of gear sets 105 that drive opposing rubber double rollers 106 to rotate in opposite directions. The machine body 101 is located above the base 2, and the base 2 has four corner bosses 3 fixedly attached. Guide rods 4 are fixed to the opposite faces of the bosses 3 at the front and rear ends, and the guide rods 4 slide in cooperation with the guide sleeves 102. A conveyor belt 5 is located in the middle of the base 2, and an adjustment assembly 6 is fixed at the rear end of the base 2. The adjustment assembly 6 includes a second motor 601, a rotating rod 602, a pin 603, and a through hole 604. The output end of the second motor 601 is fixedly connected to the rotating rod 602, and the pin 603 is inserted laterally into the end of the rotating rod 602. A through hole 604 is also provided longitudinally at the end of the rotating rod 602. The adjustment assembly 6 also includes an adjustment mechanism. The system includes a rod 605, an end 606, and a connecting rod 607. An adjusting rod 605 is slidably fitted inside a through hole 604 and is fixed to a rotating rod 602 via a pin 603. An end 606 is fixed to the end of the adjusting rod 605, and a connecting rod 607 is rotatably connected to the outside of the end 606. The end of the connecting rod 607 is rotatably connected to the machine body 101 via a connecting pin 103. On the other hand, by changing the extension length of the adjusting rod 605 through the pin 603, the rotation radius of the connecting rod 607 driven by the end 606 of the adjusting rod 605 is adjusted, thereby adjusting the reciprocating stroke length of the folding assembly 1 and thus adjusting the folding length of the nonwoven fabric.

[0023] A nonwoven fabric folding machine is provided, which is equipped with the above-mentioned folding mechanism. This provides a new type of nonwoven fabric folding method, which can quickly complete multiple folds of nonwoven fabric. It is fast, highly accurate, and the width and length of the folds are adjustable, making it highly adaptable.

[0024] As shown in Figure 1, a nonwoven fabric folding machine includes a folding frame 7, a conveyor belt 5 at the front end of the folding frame 7, an unwinding roller 8 rotatably mounted on the folding frame 7, and a tensioning roller 9 rotatably mounted on the top of the front end of the folding frame 7.

[0025] [Amended according to Rule 26, August 21, 2024] Working principle: When using this folding mechanism and non-woven fabric folding machine, the non-woven fabric is pulled out by the unwinding roller 8 at the bottom rear end of the folding frame 7 and wound around to the tensioning roller 9 at the top front end, and finally placed between the rubber double rollers 106. The motor 104 drives the rubber double rollers 106 to rotate in opposite directions through the gear set 105. Under the action of friction, the non-woven fabric is continuously discharged, and it also has a certain leveling effect. On the one hand, this application provides a sliding adjustable width adjustment plate 107 at the other end of the machine body 101 to adjust the folding width of the non-woven fabric. On the other hand, the output rod 602 of the motor 2 601 rotates and transmits power to the connecting rod 607 through the adjusting rod 605. Component 6 is an eccentric wheel and rocker arm structure, in which the rotating rod 602 and the adjusting rod 605 form the eccentric wheel. By adjusting the length of the adjusting rod 605, the center distance of the eccentric wheel can be adjusted, thereby adjusting the reciprocating stroke. This drives the guide sleeves 102 at both ends of the machine body 101 to slide on the guide rods 4 on the opposite sides of the front and rear bosses 3. During the reciprocating sliding process of the folding component 1, the non-woven fabric is continuously folded. The extension length of the adjusting rod 605 is changed by the pin 603, thereby adjusting the rotation radius of the lower connecting rod 607 driven by the end 606 of the adjusting rod 605, thereby adjusting the reciprocating stroke length of the folding component 1, and thus adjusting the folding length of the non-woven fabric. After the non-woven fabric has completed the preset number of folds, it is cut and fed by the conveyor belt 5 to complete the production, which has a higher degree of automation.
