Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a trimming machine for nonwoven fabric production. Background Technology

[0002] In traditional techniques, when trimming the edges of nonwoven fabrics, workers need to hold the cutting equipment or control the nonwoven fabric to cut and trim the edges, which limits the efficiency of trimming.

[0003] To address the aforementioned issues, patent document CN220952690U discloses a meltblown nonwoven fabric production trimming machine. This machine includes a worktable, a feeding mechanism fixedly mounted on the top of the worktable, an electric push rod mounted on the top of the worktable, a trimming cutter movably connected to the top of the electric push rod, a receiving mechanism fixedly mounted on the top of the worktable, a column fixedly connected to the bottom of the worktable, a foot support fixedly connected to the bottom of the column, and a mounting plate fixedly connected to one side of the trimming cutter. This meltblown nonwoven fabric production trimming machine, through its worktable, feeding mechanism, electric push rod, trimming cutter, and receiving mechanism, achieves high working efficiency. It utilizes the feeding and receiving equipment structure to rapidly and continuously transport meltblown nonwoven fabric, and during the transport phase, the trimming cutter performs rapid trimming processing on the meltblown nonwoven fabric, thereby improving overall work efficiency and meeting user needs.

[0004] Based on the above search and combined with existing technology, it was found that when existing nonwoven fabric production trimming machines use trimming cutters to trim, the part of the fabric in contact with the cutter is prone to deformation due to friction, resulting in fine burrs or local tearing of the fabric at the cut, which affects the quality of the trimmed nonwoven fabric. Therefore, there is a need for a nonwoven fabric production trimming machine. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a trimming machine for nonwoven fabric production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A trimming machine for nonwoven fabric production includes a base, a feeding mechanism and a receiving mechanism are respectively installed on the left and right sides of the base, and a first electric push rod is also installed on the upper end of the base. The piston rod of the first electric push rod extends upward and a movable plate is fixed at its end. A trimming cutter is fixed on the upper surface of the movable plate.

[0008] A mounting bracket is fixed on one side of the base. A second electric push rod is fixed on the horizontal bar at the upper end of the mounting bracket, which is vertically corresponding to the position of the first electric push rod. The piston rod of the second electric push rod extends downward and a tensioning mechanism is installed at its lower end.

[0009] The tensioning mechanism is used to tension the nonwoven fabric from above, so that the cut portion of the nonwoven fabric remains stable.

[0010] Preferably, the tensioning mechanism includes a gantry frame and tensioning short rollers. The upper end of the gantry frame is fixed to the lower end of the piston rod of the second electric push rod. Two tensioning short rollers are provided and arranged in a mirror image. The rotating shafts of the two tensioning short rollers are rotatably connected to the lower end of the gantry frame.

[0011] Preferably, there is a gap between the two tensioning short rollers, and the gap width is consistent with the maximum width of the trimming cutter.

[0012] Preferably, an elastic clamping mechanism is installed on the movable plate. The elastic clamping mechanism is adapted to the tensioning mechanism. When the elastic clamping mechanism is not compressed, its upper end is higher than the tip of the trimming tool. When the elastic clamping mechanism is compressed, its upper end is lower than the upper part of the trimming tool and moves in contact with the bottom of the nonwoven fabric.

[0013] Preferably, the elastic clamping mechanism includes a clamping short roller and an elastic frame. There are two clamping short rollers with the same structure as the two tensioning short rollers. The axes of the clamping short rollers are parallel to those of the tensioning short rollers. The clamping short rollers are rotatably mounted on the elastic frame, and the lower end of the elastic frame is elastically connected to the movable plate.

[0014] Preferably, the elastic frame includes a movable frame and an elastic element. The upper end of the movable frame is rotatably sleeved on the rotating shaft of the pressing short roller, and the lower end of the movable frame is elastically connected to the movable plate through the elastic element.

[0016] Preferably, the elastic frame further includes a connecting guide rod, the upper end of which is fixed to the lower end of the movable frame, and the lower end of which slides through the movable plate and extends below the movable plate.

[0017] In summary, the technical effects and advantages of this utility model are as follows:

[0018] This invention, through the setting of a tensioning mechanism, uses two short tensioning rollers to stably compress the nonwoven fabric, reducing the degree of upward deformation of the nonwoven fabric at the cutting point, thereby maintaining the stability of the nonwoven fabric at the cutting point and facilitating stable trimming operations. This improves the quality of the finished nonwoven fabric after trimming. The elastic pressing mechanism further stabilizes the nonwoven fabric during the trimming process, enhancing its stability when using the nonwoven fabric trimming machine for trimming operations. This provides precise trimming and further improves the quality of the finished nonwoven fabric after trimming. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] Example: Reference Figures 1-3 The shown is a non-woven fabric production trimming machine, including a base 1. A material feeding mechanism 2 and a material receiving mechanism 3 are respectively installed on the left and right sides of the base 1. A first electric push rod 4 is also installed on the upper end of the base 1. The piston rod of the first electric push rod 4 extends upward and the end is fixed with a movable plate 41. A trimming cutter 5 is fixed on the upper surface of the movable plate 41.

[0026] A mounting bracket 11 is fixed on one side of the base 1. A second electric push rod 8, which is vertically corresponding to the position of the first electric push rod 4, is fixed on the horizontal bar at the upper end of the mounting bracket 11. The piston rod of the second electric push rod 8 extends downward and a tensioning mechanism 7 is installed at the lower end. The tensioning mechanism 7 is used to tension the non-woven fabric from above, so that the cut part of the non-woven fabric is kept stable.

[0027] The tensioning mechanism 7 includes a gantry frame 71 and tensioning short rollers 72. The upper end of the gantry frame 71 is fixed to the lower end of the piston rod of the second electric push rod 8. There are two tensioning short rollers 72 arranged in a mirror image. The rotating shafts of the two tensioning short rollers 72 are rotatably connected to the lower end of the gantry frame 71.

[0028] There is a gap between the two tensioning short rollers 72, and the gap width is consistent with the maximum width of the trimming cutter 5.

[0029] Based on the above structure, before the trimming operation, the second electric push rod 8 is activated, causing the second electric push rod 8 to push the gantry frame 71 and the tensioning short roller 72 down until the tensioning short roller 72 presses against the upper surface of the nonwoven fabric. This makes the nonwoven fabric in a tensioned state at the corresponding section of the trimming cutter 5, which is more conducive to the smooth cutting of the trimming cutter 5. At the same time, when the electric push rod 4 pushes the trimming cutter 5 up, when the tip of the trimming cutter 5 pierces the nonwoven fabric, the two tensioning short rollers 72 cooperate with each other to stably press the nonwoven fabric, reducing the degree of upward deformation of the nonwoven fabric at the cutting part, thereby maintaining the stability of the nonwoven fabric at the cutting part and facilitating stable trimming operations. This can improve the quality of the finished product after the nonwoven fabric is trimmed.

[0030] Furthermore, an elastic pressing mechanism 6 is installed on the movable plate 41. The elastic pressing mechanism 6 is adapted to the tensioning mechanism 7. When the elastic pressing mechanism 6 is not compressed, its upper end is higher than the tip of the trimming cutter 5. After the elastic pressing mechanism 6 is compressed, its upper end is lower than the upper part of the trimming cutter 5 and moves against the bottom of the nonwoven fabric.

[0031] The elastic clamping mechanism 6 includes a clamping short roller 61 and an elastic frame. There are two clamping short rollers 61, which have the same structure as the two tensioning short rollers 72. The axis of the clamping short roller 61 is parallel to that of the tensioning short roller 72. The clamping short roller 61 is rotatably mounted on the elastic frame. The lower end of the elastic frame is elastically connected to the movable plate 41.

[0032] The flexible frame includes a movable frame 62 and an elastic element. The upper end of the movable frame 62 is rotatably sleeved on the rotating shaft of the pressing short roller 61, and the lower end of the movable frame 62 is elastically connected to the movable plate 41 through the elastic element.

[0033] The elastic element includes a spring 64, the upper and lower ends of which are fixed to the lower end of the movable frame 62 and the upper end of the movable plate 41, respectively.

[0034] The flexible frame also includes a connecting guide rod 63, the upper end of which is fixed to the lower end of the movable frame 62, and the lower end of which slides through the movable plate 41 and extends below the movable plate 41.

[0035] With the elastic clamping mechanism 6 in place, when the tensioning short roller 72 tensions the nonwoven fabric, the electric push rod 4 is activated to push the trimming cutter 5 upward. During this process, the elastic clamping mechanism 6 mounted on the movable plate 41 rises synchronously, and the two clamping short rollers 61 first contact the bottom surface of the nonwoven fabric and cooperate with the two tensioning short rollers 72 to clamp the nonwoven fabric. Then, the movable plate 41 continues to rise and compresses the spring 64, thereby keeping the position of the two clamping short rollers 61 fixed. The trimming cutter 5 gradually rises and pierces the nonwoven fabric clamped by the two clamping short rollers 61 and the two tensioning short rollers 72, thus making the nonwoven fabric more stable during the trimming process. This further improves the stability of the nonwoven fabric when using the trimming machine for nonwoven fabric production, thereby providing precise trimming operations and achieving the goal of further improving the quality of the finished nonwoven fabric after trimming.

[0036] The working principle of this utility model is as follows: In daily use, before performing trimming operations, the second electric push rod 8 is activated, causing it to push the gantry frame 71 and the tensioning short roller 72 downwards until the tensioning short roller 72 presses against the upper surface of the nonwoven fabric. Then, the electric push rod 4 is activated to push the trimming cutter 5 upwards. Simultaneously, the elastic pressing mechanism 6 mounted on the movable plate 41 rises, and the two pressing short rollers 61 first contact the bottom surface of the nonwoven fabric, cooperating with the two tensioning short rollers 72 to clamp the nonwoven fabric. Afterwards, the movable plate 41 continues to rise and compress... Spring 64 keeps the positions of the two clamping short rollers 61 fixed, and the trimming cutter 5 gradually rises and pierces the nonwoven fabric clamped by the two clamping short rollers 61 and the two tensioning short rollers 72, thereby making the nonwoven fabric more stable during the trimming process, thus maintaining the stability of the nonwoven fabric at the cutting part, facilitating stable trimming operations, and further improving the stability of the nonwoven fabric when using the trimming machine for nonwoven fabric production, thereby providing precise trimming operations and achieving the goal of further improving the quality of the finished nonwoven fabric after trimming.

[0037] It should be further noted that the technical features of the material conveying mechanism, material receiving mechanism, electric push rod, etc. involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this utility model patent.
