Description

Technical Field

[0001] The invention relates to the technical field of packaging cutting and processing, in particular to an adjustable automatic longitudinal cutting machine for packaging paper. Background Art

[0002] In the modern packaging industry, packaging paper, especially corrugated boxes, is an important packaging material and is widely used in the transportation and protection of various products. Corrugated boxes, also known as corrugated boxes and paperboard boxes, are mostly made of cardboards of different shapes that are folded after specific processing. They have excellent compression resistance and cushioning properties. However, in the production process of corrugated boxes, the accuracy and efficiency of cardboard cutting directly affect the quality of the finished products and production efficiency of the boxes. Therefore, it is particularly important to develop an efficient and accurate automatic slitting machine for packaging paper.

[0003] For example, a Chinese patent discloses "a cardboard longitudinal cutting machine" (patent number: CN216884295U), which includes a mechanical arm, a first mounting block, a first connecting arm, a side baffle, a fixed head, a second connecting arm, a connecting plate, a limit fixing block, a cutting disc, and a rotating shaft. The front end face of the mechanical arm is provided with an air pipe, and a chip prevention baffle is welded on one side of the mechanical arm, and a sound insulation pad is glued to the outer surface of the chip prevention baffle. The utility model sets a chip prevention baffle. From the side view, the upper end of the chip prevention baffle is semicircular to wrap the cutting disc, and the lower end is rectangular and does not affect the cutting of the cardboard by the cutting disc. From the front view, the chip prevention baffle wraps the upper half of the cutting disc, and there is a protrusion on the left side of the lower end, which effectively prevents paper scraps from splashing when the right disc cuts the cardboard, thereby avoiding the pollution of the surrounding environment by paper scraps and the impact on the health of the staff.

[0004] However, this patent fails to fully consider the impact of the hollow elasticity of the cardboard structure on the cutting process in terms of cutting accuracy and efficiency, and this patent has a relatively low degree of automation and relies on manual operation and adjustment.

[0030] It should be further explained that the guide plates 108 on both sides are connected to the bottom of the workbench 101 through threads, and the opening of the guide cavity 111 is located below the two outermost cutters 102.

[0031] It is worth further explaining that a moving device is installed on the side of the support frame 103, and the moving device can drive the adjustment plate 104 to move left and right to adjust the position. At this time, the adjustment plate 104 moves through the adjustment guide rod 115 to support the movement guide.

[0032] Furthermore, an output drum 110 is rotatably provided at the front end of the workbench 101, and the output drum 110 plays a mobile supporting role.

[0033] Furthermore, a guide cavity 121 opening outward is provided below one side wall of the working cavity 126 , and an adjustment plate 120 capable of moving up and down is provided in the guide cavity 121 .

[0034] Furthermore, two adjustment chambers 118 are connected on the upper wall of the guide chamber 121, and the adjustment chambers 118 on both sides are symmetrically positioned. An adjustment hydraulic valve 117 is installed in the adjustment hydraulic valve 117, and a telescopic adjustment rod 119 is connected to the bottom of the adjustment hydraulic valve 117. One side end face of the adjustment rod 119 extends outward and is connected to both sides of the top of the adjustment plate 120.

[0035] It should be further explained that the adjusting hydraulic press 117 adopts a hydraulic drive mode. When the adjusting hydraulic press 117 is started, it can push the adjusting rod 119 to move downward, and drive the adjusting plate 120 to move up and down. The adjusting plate 120 that moves up and down changes the distance from the upper end of the guide cavity 121, and then through the thickness of the packaging paper in the guide cavity 121, the wrinkles on the surface of the packaging paper can be smoothed through the bottom of the adjusting plate 120 that moves up and down, so as to facilitate the subsequent packaging paper cutting work.

[0036] Furthermore, the cutting guide device 1001 also includes a plurality of lifting hydraulic devices 105 installed at the lower end of the adjustment plate 104. The lifting hydraulic devices 105 are arranged in an array. A lifting rod 106 capable of lifting and moving is disposed at the lower end of the lifting hydraulic devices 105.

[0037] It is worth further explaining that the lifting hydraulic device 105 adopts a hydraulic driving method, and when the lifting hydraulic device 105 is started, it can drive the lifting rod 106 to move up and down.

[0038] Furthermore, a vertical fixed support rod transmission shaft 123 is fixedly provided at the bottom of the adjustment plate 104, the cutting blade 112 is L-shaped, the front end of the fixed support rod transmission shaft 123 is rotatably provided with a transmission shaft 123, one end face of the transmission shaft 123 is fixedly connected with a stabilizing guide rod 124, and the lower end of the stabilizing guide rod 124 is rotatably provided with a stabilizing output wheel 125.

[0039] Furthermore, the cutter 102 is connected to the other end surface of the transmission shaft 123 , and a connector 116 is installed between the lifting rod 106 and the cutter 102 .

[0040] It should be further explained that a cutting motor is provided in the connector 116 and is power-connected to the rotating shaft of the cutting blade 112 .

[0041] Furthermore, a cutting support plate 113 is fixedly provided in the workbench 101 and below the working chamber 126 . A cutting groove 114 opening upward is provided in the cutting support plate 113 . The cutting groove 114 is used to adapt the cutting angle of the cutting blade 112 .

[0042] When using this solution, first drive the workbench 101 to move as a whole to the working position, and after it is stably placed, the front end of the packaging paper required for longitudinal cutting is inserted horizontally into the lower part of the guide cavity 121, and the adjustment hydraulic valve 117 is started. At this time, the adjustment hydraulic valve 117 is started to push the adjustment rod 119 to move downward, and drive the adjustment plate 120 to move up and down, and the distance from the upper end of the guide cavity 121 is changed by the adjustment plate 120 that moves up and down, and then through the thickness of the packaging paper in the guide cavity 121, the wrinkles on the surface of the packaging paper can be smoothed through the bottom of the adjustment plate 120 that moves up and down, so as to facilitate the subsequent packaging paper cutting work. At this time, the packaging paper is driven by the conveying device to be input from the guide cavity 121 and conveyed forward, and the output drum 110 plays a role in supporting the guiding movement.

[0043] At this time, the staff drives the adjustment plate 104 to move left and right to adjust the position according to the size of the packaging paper through the moving device installed on the side. At this time, the adjustment plate 104 moves and supports the movement and guide through the adjustment guide rod 115, and the position of the cutting guide device 1001 on each side above the packaging paper is adjusted by the adjustment plate 104, and the control position can be adjusted autonomously.

[0044] When the longitudinal cutting of the packaging paper begins, the cutting motor in the connector 116 starts and drives the cutting blade 112 to rotate at a high speed and reaches the cutting speed. At this time, with the cutting process, the lifting hydraulic device 105 starts and drives the lifting rod 106 to press down. At this time, the lifting rod 106 drives the cutter 102 to press down through the connector 116 and achieves the effect of cutting the packaging paper. At the same time, the cutting blade 112 moves below to the cutting groove 114 to provide a cutting space. When a length of packaging paper is cut, the lifting hydraulic device 105 drives the lifting rod 106 to reset. At this time, as the cutter 102 resets and rotates, it drives the transmission shaft 123 to rotate, and then drives the stabilizing guide rod 124 on the other side to reset through the transmission of the transmission shaft 123, and makes the stabilizing output wheel 125 contact and resist the surface of the packaging paper, thereby achieving that in the subsequent movement and transmission process of the packaging paper, the longitudinal movement direction of the packaging paper can be stabilized through the support and guidance of the stabilizing output wheel 125, and the stability of its movement and transmission is improved, thereby further improving the subsequent cutting accuracy.

[0045] At the same time, when the angles and spacings of the longitudinal cutting are different, and some of the cutters 102 that do not need to cut do not need to be pressed down for cutting, the corresponding stable output wheels 125 can also play a role in supporting the movement and improving the cutting stability of the packaging paper.

[0046] At the same time, during the longitudinal cutting process, the outermost waste edges of the packaging paper can fall into the guide cavity 111 due to their own gravity after being cut, so that the waste edges can be centrally recovered, which is convenient for the subsequent reuse of the materials and prevents waste of resources.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
