Description

Technical Field

[0001] The utility model relates to the technical field of cutter equipment, in particular to a cutter assembly which is easy to repair. Background Art

[0002] The packaging bags need to be cut during the production process. The existing cutting operation is to directly cut the packaging bags with a cutting tool. Since the packaging bags are not positioned, the packaging bags may shift during the cutting process, resulting in uneven cutting of the packaging bags and poor stability.

[0003] To this end, technicians in the relevant technical field have made improvements, such as the "cutting mechanism for environmentally friendly food packaging bags" proposed in Chinese patent application number CN201921440936.0. In this application document, the pre-pressing component and the cutter component are driven downward by the connecting plate, and the packaging bag will not shift during the cutting process. However, this technical solution still has shortcomings. The guide cylinder of the device can guide the cutter, but it also makes it inconvenient to repair and replace the cutter. For this reason, we proposed a cutter assembly that is easy to repair. Utility Model Content

[0022] A stopper 21 is connected to the right side of the top of the workbench 1, a discharge port 22 is opened on the right side of the bottom of the front side side panel 2, a longitudinal cylinder 23 is connected to the lower part of the rear side side panel 2, and a push bar 24 is connected to the free end of the longitudinal cylinder 23, and the area of ​​the front end surface of the push bar 24 is smaller than the area of ​​the discharge port 22 opening.

[0023] A travel groove 31 is opened on the left side of the top of the workbench 1, and a screw rod 32 is rotatably connected in the travel groove 31. A hand wheel 33 is connected to the front end of the screw rod 32. A nut seat 34 is symmetrically screwed on the outer wall of the screw rod 32, and a limit plate 35 is connected to the upper end of the nut seat 34.

[0024] T-shaped bars 61 are connected to the left and right sides of the bottom of the lifting platform 6. A pressing frame 62 is sleeved outside the T-shaped bar 61. A buffer spring 63 is connected between the bottom of the T-shaped bar 61 and the inner wall of the pressing frame 62. A rubber pad 64 is connected to the lower end of the pressing frame 62.

[0025] The vertical cylinders 7 are provided with two and are symmetrically distributed on the left and right sides of the rectangular through slot 8 to ensure the smooth lifting of the lifting platform 6.

[0026] The outer wall of the workbench 1 is connected with a PLC controller 16, and the PLC controller 16 is electrically connected to the vertical cylinder 7, the electric push rod 13 and the longitudinal cylinder 23, so as to facilitate the operation of the control components.

[0027] The specific implementation of the utility model is:

[0028] When the device is in use, an external power source is connected, and the screw rod 32 is driven to rotate through the hand wheel 33. The two nut seats 34 move close to the rear limit plate 35 and the distance between them is shortened to prevent the packaging bag from being skewed during feeding. The packaging bag is inserted under the cutting blade 11, and the end of the packaging bag abuts the stopper 21. The lifting platform 6 is driven down by the vertical cylinder 7. The guide rod 4 is used to cooperate with the sliding sleeve 5 for limiting to ensure the smooth operation of the lifting platform 6. The T-bar 61 is synchronously lowered with the lifting platform 6. The rubber pad 64 at the lower end of the pressure frame 62 first presses the packaging bag. As the lifting platform 6 continues to descend, the buffer spring 63 is shortened, and the cutting blade 11 can cut the packaging bag. After the vertical cylinder 7 retreats, the rubber pad 64 is separated from the packaging bag, and the longitudinal cylinder 23 is used to drive the push bar 24 to move forward, so that the cut packaging bag can be sent out from the discharge port 22. When the cutting blade 11 is damaged during working time, the electric push rod 13 drives the spur rack 14 to move, the spur rack 1 engages the transmission spur gear 12, and the steering shaft 9 drives the assembly seat 10 to flip, so that the upper spare cutting blade 11 can be transferred to the working position. After the processing is completed, the electric push rod 13 is reset, and the maintenance personnel can replace and repair the components at the inspection port 15, which reduces the downtime of the operator and is conducive to improving work efficiency.
