Description

Technical Field

[0001] This utility model relates to the field of foam production technology, and in particular to a continuous slitting device for foam production. Background Technology

[0002] Foam is a material made by foaming plastic particles. It has a series of characteristics such as elasticity, light weight, quick pressure-sensitive fixation, convenient use, flexible bending, ultra-thin volume, and reliable performance. In the processing and production of foam, a slitting machine is generally used to divide the whole bundle of wide foam into strips to obtain narrow foam.

[0003] Chinese Patent Publication No. CN216031055U discloses a slitting device for PE foam production, including a processing table. A fixing mechanism is movably connected to the upper middle part of the processing table. The fixing mechanism holds the foam roll body. Two electric telescopic rods are fixedly connected to the upper left and upper right parts of the processing table. By setting an adjustment mechanism and a slitting mechanism, the position of the slitting blade can be easily adjusted, which improves the practicality of the device and makes it suitable for widespread use.

[0004] The aforementioned existing technical solution has the following shortcomings: the device uses clamping blocks to hold the foam passing through the middle from left to right. However, when the foam moves horizontally, the traction angle is prone to change, which makes the foam prone to being over-compressed to one side of the clamping block, thus producing wrinkles. Although the structure guides the foam, it does not correct the foam that is tilted to one side, so there is room for improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a continuous slitting device for foam production, so as to solve the problem mentioned in the background art that the existing continuous slitting device for foam production is not easy to correct the angle of foam that is tilted to one side, resulting in uneven slitting width.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a continuous slitting device for foam production, comprising a base plate, a plurality of tension rollers connected to one side of the top of the base plate via a support plate, the plurality of tension rollers being triangularly distributed, and two vertically distributed take-up rollers connected to the other side of the top of the base plate via a support plate, a fixed frame fixed at the center of the top of the base plate, the two sides of the top of the fixed frame being protruding, a through hole being provided at the protruding position of the top of the fixed frame, a return mechanism being provided inside the fixed frame, the two sides of the top of the return mechanism extending to the outside of the through hole, a U-shaped frame fixed at the top of the base plate on both sides of the fixed frame, a slitting mechanism being provided at the top of the U-shaped frame, the bottom end of the slitting mechanism being located in the gap of the protruding position on the fixed frame, limit components being provided on both sides inside the U-shaped frame, the inner sides of the limit components being located at the protruding position of the fixed frame, and the limit components and the return mechanism being electrically connected.

[0008] Preferably, the rotation direction of the rotating wheel is parallel to the horizontal movement direction of the foam, and the rotation direction of the rotating wheel is perpendicular to the horizontal movement direction of the connecting rod.

[0009] Preferably, L-shaped guide plates are fixed on both sides inside the fixing frame, and the top of the L-shaped guide plates abuts against the bottom of the connecting rod located above.

[0013] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0014] 1. The foam is guided by the limiting plates on both sides, and the pressure sensor detects the pressure to determine which side the foam tilts during horizontal transmission, thereby controlling the rotation of the electric gear. The rotating wheel can directly transport the foam in the left and right directions during the transmission process, thereby correcting the conveying angle of the foam to ensure that the cutting width of the wide foam is uniform by the upper cutting blade. The telescopic nature of the electric telescopic rod can guide the foam of different widths.

[0024] Combination Figures 1-4This utility model discloses a continuous slitting device for foam production, comprising a base plate 1. Multiple tension rollers 2 are connected to one side of the top of the base plate 1 via a support plate, and the tension rollers 2 are arranged in a triangular pattern. Two vertically distributed take-up rollers 5 are connected to the other side of the top of the base plate 1 via a support plate. A fixing frame 3 is fixed at the center of the top of the base plate 1. The two sides of the top of the fixing frame 3 are protruding, and through holes 10 are provided at the protruding positions of the top of the fixing frame 3. A return mechanism 7 is provided inside the fixing frame 3, and both sides of the top of the return mechanism 7 extend to the outside of the through holes 10. U-shaped frames 4 are fixed to the top of the base plate 1 on both sides of the fixing frame 3. A slitting mechanism 9 is provided at the top of the U-shaped frame 4, and the bottom end of the slitting mechanism 9 is located in the gap of the protruding position on the fixing frame 3. Limiting components 6 are provided on both sides inside the U-shaped frame 4, and the inner sides of the limiting components 6 are located at the protruding positions of the fixing frame 3. The limiting components 6 and the return mechanism 7 are electrically connected.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example 1

[0027] Combination Figure 1 , Figure 2 and Figure 4 The return mechanism 7 includes two horizontally distributed electric gears 71 inside the fixed frame 3. A toothed chain 72 is sleeved between the two electric gears 71. Multiple connecting rods 73 are fixedly connected to the outer side of the toothed chain 72. Rotating wheels 74 are rotatably connected to both sides of the connecting rods 73. The outer side of the rotating wheels 74 extends to the outside of the through hole 10. The rotation direction of the rotating wheels 74 is parallel to the horizontal movement direction of the foam, and the rotation direction of the rotating wheels 74 is perpendicular to the horizontal movement direction of the connecting rods 73. The two sides inside the fixed frame 3 are fixedly connected to the connecting rods 73. An L-shaped guide plate 8 is fixed, and the top of the L-shaped guide plate 8 abuts against the bottom of the connecting rod 73 located above; the limiting component 6 includes an electric telescopic rod 61 fixed to the upper end of the inner side wall of the U-shaped frame 4, a limiting plate 63 is fixed to one end of the electric telescopic rod 61, a pressure sensor 64 is provided on the inner side of the limiting plate 63, the pressure sensor 64 and the electric gear 71 are connected by electricity, and guide rods 62 are fixed to both ends of the limiting plate 63 near the electric telescopic rod 61, and the outer ends of the guide rods 62 penetrate the side wall of the U-shaped frame 4.

[0028] In this embodiment, wide-width foam is wound in a W-shape from multiple tension rollers 2, with one end of the foam passing between the U-shaped frame 4 and the fixed frame 3. The foam on the fixed frame 3 is cut by the slitting blade 93. The cut foam is then alternately wound onto different upper and lower take-up rollers 5 to prevent the cut foam from overlapping and to ensure the smooth winding of the take-up rollers 5. Before cutting, the electric telescopic rod 61 is activated to extend and retract, adjusting the distance between the two limit plates 63 on the left and right sides, so that both sides of the foam are respectively aligned with the pressure sensors on the same side. When the foam on the fixed frame 3 shifts left and right during horizontal movement, the pressure sensors 64 on both sides experience a larger error in the compressive force. The pressure sensor 64 on one side experiences a greater compressive force, which causes it to control the electric gear 71 to rotate, causing the gear chain 72 to move. This causes the rotating wheel 74 to translate in a direction perpendicular to the overall movement of the foam, moving the foam away from the side that is over-compressed. This achieves the position calibration, ensuring that the foam always moves smoothly in one direction and maintaining the consistency of the cutting width.

[0029] Example 2

[0030] Combination Figure 1 , Figure 3 The limiting component 6 includes an electric telescopic rod 61 fixed to the upper end of the inner wall of the U-shaped frame 4. One end of the electric telescopic rod 61 is fixed to a limiting plate 63. A pressure sensor 64 is provided on the inner side of the limiting plate 63. The pressure sensor 64 and the electric gear 71 are electrically connected. Guide rods 62 are fixed to both ends of the limiting plate 63 near the electric telescopic rod 61. The outer ends of the guide rods 62 penetrate the side wall of the U-shaped frame 4. The slitting mechanism 9 includes an adjusting component 91 set at the top of the U-shaped frame 4. Multiple connecting rods are evenly installed at the bottom end of the adjusting component 91. The bottom of the connecting plate 92 is equipped with a slitting blade 93; the adjusting assembly 91 includes a guide hole 911 opened at the top of the U-shaped frame 4, and multiple threaded posts 912 are fixed at equal intervals on both sides of the top of the guide hole 911. An adjusting plate 913 is sleeved between the two sets of threaded posts 912. The bottom of the adjusting plate 913 is fixedly connected to the top of the connecting plate 92 that passes through the guide hole 911. Locking nuts 914 are sleeved on the outside of the threaded posts 912, and the bottom of the locking nuts 914 abuts against the top of the adjusting plate 913.

[0031] In this embodiment, by tightening the locking nut 914, the adjusting plate 913 is lifted upward, thereby adjusting the position of the adjusting plate 913 on the U-shaped frame 4 to the left and right, so as to change the position of the slitting blade 93, thereby changing the slitting width. At the same time, with the cooperation of the left and right threaded columns 912, the stability of the position of the adjusting plate 913 is further ensured.
