Detailed Implementation
[0018] Please see Figures 1 to 4 ,in, Figure 1 This is a structural schematic diagram of the slitting device of this utility model. Figure 2 This is a schematic diagram of the slitting device of this utility model from another direction. Figure 3 This is a front view of the slitting device of this utility model. Figure 4 This is a structural schematic diagram of the mounting rod and mounting column of this utility model.
[0019] This utility model provides a slitting device, including a base 101 and a slitting mechanism. The slitting mechanism includes a mounting frame 102, two sliding rods 103, a mounting plate 104, a pressure rod 107, a telescopic assembly, a cutter 108, and a feeding assembly. The telescopic assembly includes a return spring 106 and a pressure block 105. The mounting frame 102 has a through groove 109. The feeding assembly includes a fixing frame 116, a pressure kit, a fixing frame 111, a mounting rod 112, a mounting column 113, and a support frame 114. The pressure kit includes a telescopic rod 115 and a pressure spring 110. The aforementioned solution solves the problem in the prior art where, after the operator holds the scissors for a long time to slit plastic film, it is difficult for the operator to control the scissors to move in a straight line, resulting in a slowdown in the operator's slitting speed and low slitting efficiency.
[0020] In this embodiment, the mounting bracket 102 is fixedly connected to one end of the base 101, the two sliding rods 103 are respectively fixedly connected to both ends of the mounting bracket 102 and located inside the mounting bracket 102, the two ends of the mounting plate 104 are respectively slidably connected to the two sliding rods 103 and located inside the mounting bracket 102, the pressure rod 107 is slidably connected to the mounting plate 104 and passes through the mounting plate 104, the telescopic assembly is disposed between the pressure rod 107 and the mounting plate 104 and is located above the mounting plate 104, the cutter 108 is fixedly connected to the pressure rod 107 and is located below the pressure rod 107, and the feeding assembly is disposed on the base 101. When using this device to cut plastic film, the plastic film roll is installed on the feeding assembly. The operator pulls one end of the plastic film outward, and the plastic film is located between the mounting frame 102 and the cutter 108. When the plastic film is pulled out to an appropriate length, the operator presses down on the pressure rod 107 to make the cutter 108 contact the plastic film. Then, the mounting plate 104 is slid, and the mounting plate 104 drives the cutter 108 to slide, and the cutter 108 cuts the plastic film. The process of cutting plastic film in the above manner is simple, and the operator can work for a long time without the efficiency of cutting plastic film decreasing, thereby improving the cutting efficiency of the device.
[0021] Furthermore, the pressure block 105 is fixedly connected to the pressure rod 107 and is located above the pressure rod 107. The two ends of the return spring 106 are fixedly connected to the mounting bracket 102 and the pressure block 105 respectively, and the pressure rod 107 is located inside the return spring 106.
[0022] In this embodiment, when the plastic film is stretched to an appropriate length, the operator presses down on the pressure block 105, compressing the return spring 106 and causing the cutter 108 to contact the plastic film. Then, the mounting plate 104 slides, causing the cutter 108 to slide. After the cutter 108 has finished cutting the plastic film, the operator releases the pressure block 105. The return spring 106 extends under its own elastic potential energy, causing the pressure block 105, the pressure rod 107, and the cutter 108 to move upward to their initial positions, facilitating subsequent cutting of the plastic film.
[0023] Furthermore, the through groove 109 is disposed on the mounting bracket 102 and located below the cutter 108.
[0024] In this embodiment, when cutting the plastic film, the cutter 108 cuts the plastic film above the through groove 109. The through groove 109 can prevent the cutter 108 from colliding with the mounting bracket 102, thereby protecting the blade of the cutter 108 and extending the service life of the cutter 108.
[0025] Furthermore, the fixing frame 116 is fixedly connected to one end of the base 101, the pressure kit is disposed between the fixing frame 116 and the fixing frame 111, one end of the mounting rod 112 is located inside the fixing frame 111, the other end of the mounting rod 112 is fixedly connected to the mounting column 113, the support frame 114 is slidably connected to the mounting column 113, and the support frame 114 is fixedly connected to the base 101.
[0026] Furthermore, both ends of the telescopic rod 115 are fixedly connected to the fixing frame 116 and the fixing frame 111, respectively, and both ends of the pressure spring 110 are fixedly connected to the fixing frame 116 and the fixing frame 111, respectively, and the telescopic rod 115 is located inside the pressure spring 110.
[0027] In this embodiment, when installing the plastic film roll, the mounting rod 112 is passed through the film roll, and the mounting rod 112 and the film roll can rotate relative to each other. One end of the mounting rod 112 is inserted into the fixing frame 111, and the fixing frame 111 is squeezed. The pressure spring 110 and the telescopic rod 115 are compressed. Then, the mounting post 113 on the mounting rod 112 is inserted into the support frame 114. At this time, the pressure spring 110 extends under its own elastic potential energy. The pressure spring 110 is still in a compressed state, so that the mounting rod 112 is clamped between the fixing frame 111 and the support frame 114. When one end of the plastic film is pulled, the plastic film roll and the mounting rod 112 rotate relative to each other, and the plastic film is stretched. The plastic film roll is installed in the above manner, and it is convenient to remove the used plastic film roll from the mounting rod 112.
[0028] When using this invention to cut plastic film and install the plastic film roll, the mounting rod 112 is passed through the film roll, and the mounting rod 112 and the film roll can rotate relative to each other. One end of the mounting rod 112 is inserted into the fixing frame 111, and the fixing frame 111 is compressed. The pressure spring 110 and the telescopic rod 115 are compressed. Then, the mounting post 113 on the mounting rod 112 is inserted into the support frame 114. At this time, the pressure spring 110 extends under the action of its own elastic potential energy. The pressure spring 110 is still in a compressed state, so that the mounting rod 112 is clamped between the fixing frame 111 and the support frame 114. The operator pulls one end of the plastic film outward, with the plastic film positioned between the mounting bracket 102 and the cutter 108. When the plastic film is pulled out to an appropriate length, the operator presses down on the pressure block 105, compressing the return spring 106 and causing the cutter 108 to contact the plastic film. Then, the mounting plate 104 slides, causing the cutter 108 to slide and cut the plastic film. This method of cutting the plastic film is simple, and the operator can work for extended periods without sacrificing efficiency, thus improving the cutting efficiency of the device.
