Description

Technical Field

[0001] This utility model relates to the field of curtain slat production technology, specifically to an online punching device for soft curtain doors. Background Technology

[0002] Curtain slats are the main components used in folding products such as folding doors and curtains. Typically, curtain slats are connected by pull cords, which pass through holes in the slats. These holes are neatly arranged along the length of the slats. Therefore, perforations are required during the production of curtain slats. Current technology mainly uses a punching needle to punch holes one by one on the slats. This method is not only inefficient but also prone to inaccurate slat positioning, resulting in uneven perforation.

[0003] Chinese Patent No. CN208483948U discloses a curtain slat punching machine, the structure of which includes a hydraulic pump station and a feeding conveyor belt, a punching station, and a receiving conveyor belt connected sequentially along the curtain slat transmission direction. The feeding conveyor belt and the receiving conveyor belt are respectively provided with limiting members for limiting the transmission direction of the curtain slat. Above the punching station is an upper pressure block that can fit with the upper surface of the curtain slat, and below the punching station is an upper pressure block that can fit with the lower surface of the curtain slat. The upper pressure block and the lower pressure block press against each other to position the curtain slat at the punching station. The lower pressure block is provided with a punching needle with the needle tip facing the curtain slat. The upper pressure block is fixed on the hydraulic pump station, and the lower pressure block is fixedly set. The hydraulic pump station drives the upper pressure block and the lower pressure block to press against each other, so that the punching needle punches holes in the curtain slat.

[0004] However, the above has the following shortcomings:

[0005] 1. According to the description in the above patent, the punching operation is completed by setting the punching needles on the upper and lower pressure blocks to squeeze the door curtain together. Although the punching efficiency can be guaranteed, it cannot avoid the situation that when all the punching needles work together, the punching needles squeeze and stretch the soft curtain door, causing the soft curtain door to deform. After the punching is completed, the deformation disappears, resulting in the punching deformation.

[0006] 2. The above-mentioned patent uses two fixed pressure blocks to punch holes in the door curtain. If the door curtain is not stopped during punching, the relative movement of the punching holes against the soft curtain door belt will cause the shape of the holes to deform. However, if the punching is stopped in the middle to ensure the shape of the holes, the work efficiency will be reduced. Utility Model Content

[0007] To overcome the shortcomings of the prior art, this utility model solves the technical problem by using the bottom of the outer shell and the perforated stamping plate to press the soft curtain strip together, making each area requiring punching independent. This avoids the deformation of the soft curtain strip between holes during punching, which can cause changes in the shape of the punched holes. By setting guide rails, the punching device and the soft curtain strip move together, so that the soft curtain strip and the punching device remain relatively stationary during punching, ensuring the shape of the punched holes. Furthermore, the soft curtain strip can maintain consistent transport during the punching process, improving work efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a soft curtain door with an online punching device, comprising a housing and a movable plate. Multiple knife holders are fixedly connected to the lower part of the movable plate, and each knife holder has a knife edge fixedly connected to its lower end. Multiple sliding rods are slidably connected to the movable plate, and a spring is fixedly connected between each sliding rod and the movable plate. A stamping plate is fixedly connected to the lower end of each sliding rod below the movable plate, and the stamping plate has holes corresponding to the positions of each knife edge.

[0009] Furthermore, movable sliders are symmetrically distributed and fixedly connected to the surface of the movable plate, and trapezoidal grooves are provided on both sides of the inner wall of the outer shell. Each movable slider is slidably connected in the trapezoidal groove at the corresponding position. The trapezoidal groove is an inverted trapezoid with a smaller bottom and a larger top.

[0010] Furthermore, multiple lead screws are rotatably connected inside the outer casing, and multiple motors are fixedly connected to the surface of the outer casing at the corresponding positions of the lead screws. The power end of each motor is driven and connected to the lead screw. A slide rod is fixedly connected to the center of the moving plate, and a slider is slidably connected to the surface of the slide rod. The slider is driven and connected to the lead screw.

[0011] Furthermore, the outer shell is provided with a spring two at each position corresponding to each trapezoidal groove. One end of the spring two is fixedly connected to a limiting block, which is slidably connected inside. The end of the limiting block inside the trapezoidal groove is perpendicular to the inclination angle of the groove surface of the trapezoidal groove.

[0012] Furthermore, multiple support seats are fixedly connected to the bottom of the outer shell, and two sets of guide roller support frames are symmetrically distributed and fixedly connected to the lower end of the outer shell surface, with guide rollers rotatably connected between each set of guide roller support frames.

[0013] Furthermore, the bottom of the outer shell has multiple openings, and waste inlets are fixedly connected to all the outer periphery of the bottom of the outer shell, with a waste bin provided below the waste inlets.

[0014] Furthermore, a fan is fixedly connected to the surface of the outer shell, the air outlet of the fan is set as a round hole, an air passage is opened inside the slide rod, an air guide pipe is connected between the fan and the slide rod, the slide rod is fixedly connected to a moving plate, and the moving plate is fixedly connected to multiple knife holders with ring-shaped blades.

[0015] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) The use of a perforated pressure plate makes each punching position independent, which avoids the deformation of the soft curtain door due to the punching action during punching, so that the holes will not affect each other and the shape of the punching will not change.

[0017] (2) Due to the setting of the slide and the slider, the punching device can move together with the soft curtain door belt, so that the punching device and the soft curtain door are relatively stationary during punching, which ensures the shape of the punch and the soft curtain door belt can be continuously transported during punching, thus improving work efficiency.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a soft curtain door cleaning device includes a housing 10. Four support bases 11 are symmetrically distributed and fixedly connected to the bottom of the housing 10. Multiple waste troughs 32 are opened at the bottom of the housing 10. Waste guides 12 are fixedly connected to the periphery of all waste troughs 32. A waste bin 13 is provided below the waste guide 12. Two sets of guide roller support frames 16 are symmetrically distributed and fixedly connected to the outside of the housing 10. A guide roller 17 is rotatably connected inside each set of guide roller support frames 16.

[0026] By setting the guide roller support frame 16 and the guide roller 17, the soft door curtain belt is guided, so that the soft door curtain belt enters the punching device smoothly, resulting in a better punching effect.

[0027] The waste material is controlled by the waste guide 12 to prevent the waste material from falling out of the waste trough 32 and to be collected in the waste bin 13 for later processing.

[0028] like Figure 3 , Figure 4 and Figure 5 As shown, two lead screws 21 are symmetrically distributed and rotatably connected to the upper end of the outer shell 10. Motors 18 are symmetrically distributed and fixedly connected to the upper surface of the outer shell 10. The transmission end of each motor 18 is connected to the lead screw 21. Slider 19 is connected to the surface of the two lead screws 21. Sliding rod 20 is slidably connected to the center of slider 19. Moving plate 22 is fixedly connected to the lower end of sliding rod 20. Moving sliders 26 are symmetrically distributed and fixedly connected to the surface of moving plate 22. A trapezoidal groove 29 is opened on the inner wall of the outer shell 10. The moving sliders 26 are slidably connected in the trapezoidal groove 29.

[0029] The motor 18 drives the lead screw 21 to rotate, causing the slider 19 on the lead screw 21 to slide. The slider 19 drives the slide rod 20 to move, causing the movable plate 22, which is fixedly connected to the slide rod 20, to move. Because the movable slider 26 on the movable plate 22 slides in the trapezoidal groove 29, the trapezoidal groove 29 restricts the direction of movement of the movable plate 22, causing the movable plate 22 to move along the trajectory of the trapezoidal groove 29.

[0030] like Figure 4 As shown, the four corners of the movable plate 22 are slidably connected with slide rods 23. Each slide rod 23 is fixedly connected to the movable plate 22 with a spring 24 surrounding the slide rod 23. The lower end of each slide rod 23 is fixedly connected to the same stamping plate 25. The lower end of the movable plate 22 is fixedly connected with multiple horizontally arranged tool holders 28. The lower end of each tool holder 28 is fixedly connected with a cutting edge 27. The stamping plate 25 has openings that correspond one-to-one with the tool holders 28 and the cutting edges 27.

[0031] By setting up a perforated pressure plate to make each opening area independent, and using a knife holder 28 and a knife edge 27 to punch the soft curtain door belt, the shape of each punch is stable and will not interfere with each other.

[0032] like Figure 5 As shown, the outer shell 10 has a parallel slot 33 at the trapezoidal slide groove 29. A spring 30 is connected to the parallel slot 33 of the outer shell 10. One end of the spring 30 is fixedly connected to a limiting block 31. The limiting block 31 is slidably connected in the parallel slot 33. The end of the limiting block 31 located in the trapezoidal slide groove 29 is perpendicular to the inclination angle of the inclined surface of the trapezoidal slide groove 29.

[0033] By setting the limit block 31, the movable slider 26 will not return to the inclined groove of the trapezoidal slide 29 due to gravity, thus ensuring the normal movement of the device.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a fan 14 is fixedly connected to the surface of the outer casing 10. The air outlet of the fan 14 is set as a round hole. An air guide pipe 15 is connected to the air outlet of the fan 14. An air passage is opened inside the slide rod 20. The air guide pipe 15 is connected to the slide rod 20. The slide rod 20 is fixedly connected to the moving plate 22. The moving plate 22 is fixedly connected to each tool holder 28.

[0035] The blower 14 blows air through the air duct 15 into the slide bar 20, and blows it out from the air outlet of each knife holder 28 at the moving plate 22, blowing out the soft curtain door waste cut by the knife edge 27.

[0036] In this embodiment, initially, the movable slider 26 is located in the upper groove of the trapezoidal groove 29, the spring 24 is in a stretched state, and the tool holder 28 with the cutting edge 27 is retracted between the stamping plate 25 and the movable plate 22.

[0037] When in use, the operator connects the device to the power supply, guides the soft curtain door belt from the guide roller 17 on the side away from the limit block 31, passes it between the outer shell 10 and the stamping plate 25, and then exits it from the guide roller 17 on the other side. The operator then turns on the motor 18 and the fan 14.

[0038] The motor 18 drives the lead screw 21 to rotate, causing the slider 19 to slide to the left, which in turn causes the slide rod 20 inside the slider 19 to move to the left. This causes the moving plate 22 connected to the lower end of the slide rod 20 to move to the left, and the moving slider 26 connected to the surface of the moving plate 22 to move to the left. Due to the restriction of the trapezoidal groove 29, the moving slider 26 can only slide within the trapezoidal groove 29.

[0039] When the movable plate 22 moves to the leftmost end of the trapezoidal slide 29, the motor 18 reverses, and the lead screw 21 drives the slider 19 to move the slide rod 20 and the movable plate 22 to the right. Under the constraint of the trapezoidal slide 29, the movable plate 22 and the movable slider 26 move downward due to gravity. The movable slider 26 slides along the left inclined side of the trapezoidal slide 29, and the movable plate 22 drives the slide rod 20 to slide downward within the slider 19. As the slider 19 continues to slide to the right, the movable slider 26 continues to move downward along the left inclined side. This causes the stamping plate 25 to contact the soft curtain strip. When the movable slider 26 slides into the lower parallel groove of the trapezoidal slide groove 29, the stamping plate 25 and the outer shell 10 press the soft curtain strip together, causing the slide rod 23 connected to the stamping plate 25 to move upward relative to the movable plate 22. The spring 24 connected between the slide rod 23 and the movable plate 22 is stretched and accumulates elasticity. Because the distance between the movable plate 22 and the stamping plate 25 is shortened, the cutting edge 27 and the cutting tool holder 28 are exposed from the holes opened on the stamping plate 25 to punch holes in the soft curtain strip.

[0040] When the movable plate 22 moves to the rightmost end of the lower flat groove of the trapezoidal slide 29, the slider 19 continues to slide to the right. Because of the restriction of the trapezoidal slide 29, the movable slider 26 is forced to rise. As the movable slider 26 rises, the tension between the slider 23 and the movable plate 22 is lost, and the spring 24 releases its elasticity, causing the movable plate 22 to move away from the stamping plate 25. This causes the knife edge 27 and the knife holder 28 connected to the movable plate 22 to retract between the stamping plate 25 and the movable plate 22. As the movable slider 26 continues to slide upward, the stamping plate 25 separates from the soft curtain door belt. Because the movable plate 22 rises, the slider 20 slides upward within the slider 19.

[0041] When the movable slider 26 slides upward along the right inclined groove of the trapezoidal slide 29, the movable slider 26 presses the inclined surface of the limiting block 31, causing the inclined surface of the limiting block 31 to be forced to retract into the parallel groove inside the outer shell 10. The spring 30 connected to the limiting block 31 is compressed and accumulates elasticity. When the movable slider 26 slides to the rightmost side of the upper flat groove of the trapezoidal slide 29, the spring 30 releases its elasticity, causing the limiting block 31 to return to its original position, preventing the movable slider 26 from moving back due to gravity. The motor 18 reverses again, causing the slider 19 to return to the origin with the sliding rod 20 and the movable plate 22 and repeat the above operation.

[0042] When the cutter holder 28 and the cutting edge 27 are exposed from the opening of the stamping plate 25, and the soft curtain door strip is punched, the cut soft curtain door waste is inside the cutting edge 27. Because the blower 14 blows air, the airflow is blown out from the air outlet of the blower 14 and guided by the air duct 15 into the air passage of the slide rod 20. Because the air passage of the slide rod 20 is connected to the moving plate 22 and all the cutter holders 28 on the moving plate 22, the airflow is blown out from the location of each cutter holder 28, so that the waste inside the cutting edge 27 is blown out of the waste trough 32 under the action of the airflow. Under the guidance of the waste guide port 12, it falls into the waste box 13 and is collected, which facilitates the subsequent waste processing operation.

[0043] The aforementioned fan 14 and motor 18 are both mature existing technologies, and will not be described in detail here.
