Description

Technical Field

[0001] This utility model belongs to the field of trimming technology for knitted fabrics, and in particular relates to a trimming device for knitted fabrics. Background Technology

[0002] Knitted greige fabric is a type of textile raw material fabric that has not undergone printing and dyeing processing. It is mainly used for printing and dyeing processing. It can be classified according to different standards. According to the raw material classification, knitted greige fabric can be divided into pure textile fabric, blended textile fabric, mixed fabric and interwoven fabric. Pure textile fabric is a fabric made of the same type of fiber, such as cotton fabric, wool fabric, silk fabric, etc.

[0003] Due to varying actual needs, the width of knitted fabrics comes in various sizes, which interferes with the adjustment of the cutting tools on the trimming equipment. However, the adjustment of the cutting tools requires specialized personnel, as other staff cannot easily adjust them, resulting in low efficiency.

[0004] To address these issues, we provide a trimming device for knitted fabrics. Utility Model Content

[0005] The purpose of this invention is to provide a trimming device for knitted fabrics. The device is driven by a motor to rotate a rotating disk. As the disk rotates, it moves a connecting rod, which pulls the trimming blades and changes the distance between the two blades. This allows it to adapt to knitted fabrics of different widths, solving the problems of inconvenient adjustment and low efficiency of existing trimming blades.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a trimming device for knitted fabric, including a support component, a frame, a conveying roller disposed on the frame, a take-up roller disposed on one side of the top of the frame, and a fabric body disposed on the conveying roller and the take-up roller.

[0008] The trimming component includes a drive assembly disposed on the frame, one side corresponding to the take-up roller, and a trimming component disposed inside the drive assembly;

[0009] The driving component can control the movement of the trimming component to meet the trimming requirements of fabrics of different sizes.

[0010] The present invention is further configured such that the driving assembly includes a fixed frame fixed to the top of the frame, a driving motor disposed at the top of the fixed frame, a rotating disk disposed at the driving end of the driving motor, and connecting rods disposed on both sides of the bottom of the rotating disk.

[0011] The present invention is further configured such that the trimming assembly includes a guide rod disposed inside the fixing frame, a connecting block sleeved on the outer wall of the guide rod, a limiting rod penetrating the side wall of the connecting block, and a trimming knife disposed at the bottom end of the connecting block.

[0012] The present invention is further configured such that the connecting rod is rotatably connected to the connecting block, the guide rod and the limiting rod are uniformly fixedly connected to the fixing frame, and the connecting block is slidably connected to the guide rod and the limiting rod.

[0013] The present invention is further configured to include a tensioning component, which includes a bearing assembly disposed on the frame, a pressing assembly disposed inside the bearing assembly, and an upward moving assembly disposed inside the bearing assembly above the pressing assembly.

[0014] The present invention is further configured such that the bearing assembly includes a bearing frame fixed between two corresponding conveying rollers at the top of the frame, a fixing rod fixed inside the bearing frame, and a spring sleeved on the outside of the bearing frame.

[0015] The present invention is further configured such that the pressing component includes a first movable block sleeved on the outer wall of the fixed rod, a first rotating shaft disposed at one end opposite to the first movable block, and a pressure roller sleeved on the outer wall of the first rotating shaft.

[0016] The present invention is further configured such that the upward moving component includes a second moving block sleeved on the outer wall of the fixed rod, extension blocks fixed on both sides of the second moving block, a second rotating shaft fixed to one end of the extension block, and a support roller sleeved on the outer wall of the second rotating shaft.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model uses a corresponding controller to start the drive motor, which drives the rotating disk to rotate. When the rotating disk rotates, it causes the connecting rod to move, thereby controlling the movement of the trimming knife and thus changing the distance between the trimming knives to adapt to different widths of fabric bodies.

[0019] 2. This utility model utilizes the elastic force generated by the spring to make the second moving block and the first moving block interact with each other. Then, the fabric body is wrapped around the first moving block and the second moving block. At this time, the fabric body is tightened, which will compress the spring, thereby generating elastic force. The first moving block and the second moving block are used to tighten the fabric body, thereby avoiding wrinkles in the fabric body and thus affecting the quality of trimming.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figure 1-3 The present invention is a trimming device for knitted fabric, including a support component 100, a frame 101, a conveying roller 102 disposed on the frame 101, a take-up roller 103 disposed on one side of the top of the frame 101, and a fabric body 104 disposed on the conveying roller 102 and the take-up roller 103.

[0032] The trimming component 200 includes a drive assembly 201 disposed on the frame 101, one side corresponding to the take-up roller 103, and a trimming component 202 disposed inside the drive assembly 201.

[0033] The drive component 201 can control the movement of the trimming component 202 to meet the trimming requirements of fabrics of different sizes.

[0034] Specifically, the drive assembly 201 includes a fixed frame 201d fixed to the top of the frame 101, a drive motor 201a disposed at the top of the fixed frame 201d, a rotating disk 201b disposed at the drive end of the drive motor 201a, and connecting rods 201c disposed on both sides of the bottom of the rotating disk 201b. The trimming assembly 202 includes a guide rod 202b disposed inside the fixed frame 201d, a connecting block 202a sleeved on the outer wall of the guide rod 202b, a limiting rod 202c penetrating the side wall of the connecting block 202a, and a trimming knife 202d disposed at the bottom of the connecting block 202a.

[0035] Furthermore, the connecting rod 201c is rotatably connected to the connecting block 202a, the guide rod 202b and the limiting rod 202c are fixedly connected to the uniformly fixed frame 201d, and the connecting block 202a is slidably connected to the guide rod 202b and the limiting rod 202c.

[0036] The operation process of this embodiment is as follows: First, the drive motor 201a is started. At this time, the rotating disk 201b at the drive end of the fixed drive motor 201a will rotate. Connecting rods 201c are connected to both ends of the rotating disk 201b, and the other end of the connecting rod 201c is connected to the connecting block 202a. Therefore, when the rotating disk 201b rotates, it will drive the connecting block 202a to move through the connecting rod 201c. In addition, the connecting block 202a is penetrated by the guide rod 202b, which is fixed on the fixed frame 201d. Therefore, the guide rod 202b can make the connecting block 202a move linearly, and the limiting rod 202c can ensure the stable movement of the connecting block 202a without shaking. Therefore, when the trimming knife 202d trims the fabric body 104, it will not shake, thus the trimming effect of the fabric body 104 can be better.

[0037] Example 2

[0038] Please see Figure 1 , Figure 4 and Figure 5 Based on Embodiment 1, it also includes a tensioning component 300, which includes a bearing component 301 disposed on the frame 101, a pressing component 302 disposed inside the bearing component 301, and an upward moving component 303 disposed inside the bearing component 301 above the pressing component 302.

[0039] Specifically, the bearing assembly 301 includes a bearing frame 301a fixed at the top of the frame 101 between two conveying rollers 102, a fixing rod 301b fixed inside the bearing frame 301a, and a spring 301c sleeved on the outside of the bearing frame 301a. The pressing assembly 302 includes a first moving block 302a sleeved on the outer wall of the fixing rod 301b, a first rotating shaft 302b disposed at one end opposite to the first moving block 302a, and a pressure roller 302c sleeved on the outer wall of the first rotating shaft 302b.

[0040] Furthermore, the upward moving component 303 includes a second moving block 303a sleeved on the outer wall of the fixed rod 301b, extension blocks 303b fixed on both sides of the second moving block 303a, a second rotating shaft 303c fixed on one end of the extension block 303b, and a support roller 303d sleeved on the outer wall of the second rotating shaft 303c.

[0041] The operation process of this embodiment is as follows: the fabric body 104 is wound around the pressure roller 302c and the support roller 303d, and the normal movement of the fabric body 104 is ensured. First, when the spring 301c is in its original position, the distance between the pressure roller 302c and the support roller 303d is the farthest. When the fabric body 104 is wound around the pressure roller 302c and the support roller 303d, the fabric body 104 is pulled taut. At this time, the spring 301c deforms and generates elastic force. Then, the fabric body 104 is fixed on the take-up roller 103. When the fabric body 104 becomes loose, the elastic force of the spring 301c itself will cause the pressure roller 302c and the support roller 303d to move away from each other, pulling the fabric body 104 and making the fabric body 104 taut, so as to avoid the fabric body 104 being too loose and affecting the quality of trimming.
