Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a trimming device with a limiting mechanism. Background Art

[0002] Corrugated cardboard was first used in the late 18th century. In the early 19th century, its application increased significantly due to its light weight, low price, wide range of uses, simple production, and ability to be recycled and even reused. By the early 20th century, it had been widely popularized, promoted and applied for packaging of various commodities. Since packaging containers made of corrugated cardboard have unique properties and advantages in beautifying and protecting the goods inside, they have achieved great success in the competition with various packaging materials. It has become one of the main materials for making packaging containers that has been used for a long time and has shown rapid development.

[0003] Corrugated paper is a board-shaped material made by gluing noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into two categories: single corrugated board and double corrugated board. According to the size of the corrugation, it is divided into five types: A, B, C, E, and F. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled. Corrugated paper can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used.

[0004] A trimming device is often used in the cutting process of corrugated cardboard. However, the existing trimming device lacks an effective movable limiting mechanism when cutting the corrugated cardboard, and can only cut the corrugated cardboard to a certain length, which affects its use. Therefore, we propose a trimming device with a limiting mechanism. Utility Model Content

[0027] In one embodiment of the utility model, the limiting assembly 6 includes: a driving plate 61, a driving plate 61 is fixedly connected to the outer wall of the side of the connecting plate 2, a moving hole 62 is opened on the upper outer wall of the front side of the driving plate 61, and a tooth hole 63 is opened below the moving hole 62; a limiting plate 64, a limiting plate 64 is movably connected to the upper outer wall of the connecting plate 2, a connecting rod 65 is inserted into the inner wall of the limiting plate 64, and a connecting block 66 is sleeved on the outer wall of the connecting rod 65, and the connecting block 66 is movably connected to the inner wall of the moving hole 62, and the connecting block 66 movably passes through the moving hole 62 and extends to the outer wall of the moving hole 62; a spring 67, a spring 67 is fixedly connected to the outer wall of the front side of the connecting block 66, and a hinge seat 68 is fixedly connected to the outer wall above the spring 67, and the hinge seat 68 The inner wall is hinged with a stopper 69. If you want to change the size of the corrugated cardboard, press down the outer wall on the side of the stopper 69 close to the spring 67 to remove the stopper 69 from the gap of the gear 610. At this time, push the limit plate 64. The outer wall below the stopper 69 is movably connected with the gear 610. After setting the size, release the stopper 69, and then the spring 67 resets the stopper 69 so that the limit plate 64 continues to be stuck, so that the gear 610 drives the limit plate 64 to move. There are two groups of gears 610. The two groups of gears 610 are mirrored on the inner wall of the tooth hole 63 with the vertical midline of the outer wall of the side of the driving plate 61 as the symmetry axis. The moving hole 62 is in the shape of a "mouth", and the gear 610 is meshed with the tooth hole 63.

[0028] In one embodiment of the present invention, the conveying assembly 7 includes a motor 71, and then the motor 71 is started, and the transmission belt 72 sleeved on the outer wall is driven to rotate by the rotation of the output end of the motor 71, and then the longitudinal threaded rods 73 on both sides are rotated by the rotation of the transmission belt 72. The outer wall of the output end of the motor 71 is sleeved with a transmission belt 72, and the inner wall of the transmission belt 72 is connected to the longitudinal threaded rod 73 for transmission. Then, the motor 71 is started, and the transmission belt 72 sleeved on the outer wall is driven to rotate by the rotation of the output end of the motor 71, and then the longitudinal threaded rods 73 on both sides are rotated by the rotation of the transmission belt 72. The longitudinal threaded rod 73 movably penetrates the connecting plate 2 and extends to the inside of the connecting plate 2. A slide groove 74 is provided on the outer wall below the connecting plate 2, and a slider 75 is movably connected to the inner wall of the slide groove 74. The upper part of the slider 75 movably penetrates the connecting plate 2 and extends to the upper outer wall of the connecting plate 2. The extending end of the slider 75 The outer wall is fixedly connected to a movable plate 76. First, the corrugated cardboard is placed on the upper outer wall of the movable plate 76. Then, the handle 78 is held and rotated. The rotation of the handle 78 drives the transverse threaded rod 79 to rotate. The inner wall above the movable plate 76 is movably connected to a clamping plate 77. The outer wall below the clamping plate 77 is plugged with a transverse threaded rod 79. The transverse threaded rod 79 rotates, and then the clamping plate 77 is driven to move toward the middle of the transverse threaded rod 79, so that the clamping plate 77 clamps the corrugated cardboard above the movable plate 76. The outer wall on the right side of the transverse threaded rod 79 is fixedly connected to a handle 78, so that the longitudinal threaded rod 73 drives the movable plate 76 to move. The slide groove 74 is in a "convex" shape. The longitudinal threaded rod 73, the slide groove 74, and the slider 75 constitute a group of movable devices. There are two groups of movable rod devices. The two groups of movable devices are mirrored and arranged on the left and right inner walls of the connecting plate 2 with the midline of the front-to-back direction of the connecting plate 2 as the symmetry axis.

[0029] Working principle: When in use, first put the corrugated cardboard on the upper outer wall of the movable plate 76, then hold the handle 78 and rotate it, and the rotation of the handle 78 drives the transverse threaded rod 79 to rotate, and the rotation of the transverse threaded rod 79 drives the clamping plate 77 to move toward the middle of the transverse threaded rod 79, so that the clamping plate 77 clamps the corrugated cardboard above the movable plate 76, and then the motor 71 is started, and the transmission belt 72 set on the outer wall is rotated by the rotation of the output end of the motor 71, and then the longitudinal threaded rods 73 on both sides are rotated by the rotation of the transmission belt 72, and then the longitudinal threaded rods 73 on both sides are rotated by the rotation of the transmission belt 72. The rotation of the longitudinal threaded rod 73 forces the slider 75 to rotate on the inner wall of the slide groove 74, thereby driving the clamping plate 77 arranged above to move so that the control box 4 controls the cutter 5 to control the cutter 5, so that the cutter 5 cuts the corrugated cardboard arranged below. If the size of the corrugated cardboard needs to be changed, the outer wall of the stopper 69 close to the spring 67 is pressed down to remove the stopper 69 from the gap of the gear 610. At this time, the limit plate 64 is pushed. After the size is set, the stopper 69 is released, and then the spring 67 resets the stopper 69 so that the limit plate 64 continues to be stuck.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
