Description

Technical Field

[0001] The utility model belongs to the technical field of carton production, and more specifically, it particularly relates to a carton cutting device for carton production. Background Art

[0002] Cartons are the most widely used packaging products, usually used as wrappers for goods or outer protectors for items. The volume of cartons can change according to the size of the goods, and they are an indispensable part of modern logistics. During the production process of cartons, cartons need to be cut and processed to obtain the required carton size.

[0003] For example, the Chinese patent with the publication number CN212603672U discloses a precise positioning and cutting device for cartons in carton production. A support frame is fixedly connected to the top end of the base. Symmetric sliding grooves are provided on the inner wall of the support frame. Pressing plates are slidably clamped in both of the two sliding grooves. A cylinder is fixedly connected to the middle position at the top end of the support frame. A telescopic rod is fixedly connected to the bottom end of the cylinder, and the bottom end of the telescopic rod is fixedly connected to the top end of the pressing plate. A cutting mechanism is embedded in the pressing plate. The structure of the utility model is scientific and reasonable, safe and convenient to use. It is provided with a rectangular groove, a screw rod, a movable plate, a buffer chamber, a buffer spring, a cutter, a knob and a belt. Through the cooperation of the cylinder and the telescopic rod, the pressing plate is pushed to move, so as to drive the cutter at the bottom end of the pressing plate to cut the carton. At the same time, due to the telescopic characteristic of the buffer spring, when pressing and cutting, the cutter is driven to contract, slowing down the impact force, avoiding the collision between the cutter and the moving plate, and reducing the damage of the cutter;

[0004] The technical solution recorded in this scheme installs a buffer spring at the upper end of the cutter, and uses the contraction of the buffer spring to avoid the collision between the cutter and the moving plate due to excessive pressure on the cutter, thus preventing the situation of cutter damage. When the cutter cuts the cardboard, it will squeeze the buffer spring and compress it to the vertex. When the cardboard is cut open, the cutter will hit the moving plate more quickly under the elastic force of the buffer spring, thereby causing damage to the cutter.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a carton cutting device for carton production is provided, in order to achieve the purpose of having more practical value. Summary of the Utility Model

[0025] Embodiment:

[0026] As shown in the appended Figure 1 to the appended Figure 4 figures:

[0027] The present utility model provides a carton cutting device for carton production, including a main body 100, a cutting mechanism 200 and a buffer mechanism 300. The main body 100 includes a box body 1001. A buffer groove 1010 is formed on one side of the upper end surface of the box body 1001. The buffer mechanism 300 includes an installation box 3001. The installation box 3001 is arranged at the bottom end of the buffer groove 1010. Fixed plates 3006 are installed on both sides inside the installation box 3001. Slide bars 3009 are fixedly installed on one side of each fixed plate 3006. The other ends of the slide bars 3009 are respectively connected to the inner side walls of the installation box 3001. First sliders 3007 are slidably installed on the slide bars 3009. First movable seats 3005 are installed at the upper ends of the first sliders 3007. A pressing plate 3002 is slidably installed inside the installation box 3001. Second movable seats 3004 are installed on both sides of the bottom end of the pressing plate 3002. Connecting rods 3003 are hinged inside the second movable seats 3004 through pins. The other ends of the connecting rods 3003 are respectively hinged to a pair of the first movable seats 3005 through pins. By installing the fixed plate 3006 inside the installation box 3001 and installing the slide bar 3009 on one side thereof and connecting it to the inner side wall of the installation box 3001, the first slider 3007 slidably installed on the slide bar 3009 is provided with the first movable seat 3005, and the connecting rod 3003 is hinged inside the first movable seat 3005. The other end of the connecting rod 3003 is hinged to the second movable seat 3004 installed at the bottom end of the pressing plate 3002. Thus, when the cutter 2004 presses down, the cardboard is first cut. When the bottom of the cutting knife contacts the upper end surface of the pressing plate 3002, the pressure of the cutter 2004 will drive the pressing plate 3002 to press down. During the process of the pressing plate 3002 pressing down, the first slider 3007 will be driven to move towards both sides of the slide bar 3009 through the connecting rod 3003, and the spring 3008 will be compressed. Therefore, the contraction of the spring 3008 plays a buffering role for the cutter 2004. After the cutting is completed, the cutter slowly rises, and the pressing plate 3002 rises together with the cutter 2004 under the elastic force of the spring 3008.

[0028] One end of each of the slide bars 3009 is sleeved with a spring 3008. The two ends of the spring 3008 are respectively connected to one side of the first slider 3007 and the inner side wall of the installation box 3001. By installing the spring 3008, a buffering effect can be achieved on the cutter 2004.

[0029] Among them, sliding grooves 1003 are provided on both sides of the upper end surface of the box body 1001, and a top plate 1005 is slidably installed between a pair of the sliding grooves 1003. By slidably installing the top plate 1005 between the sliding grooves 1003, one side of the cardboard can be limited, facilitating the user to cut the cardboard.

[0030] Among them, a moving groove 1004 is provided on the upper end surface of the box body 1001 between a pair of the sliding grooves 1003, and a moving box 1007 is installed at the bottom end of the moving groove 1004 inside the box body 1001.

[0031] Among them, a lead screw 1008 is rotatably connected inside the moving box 1007. A second slider 1009 is sleeved on the lead screw 1008. The upper end of the second slider 1009 passes through the moving groove 1004 and is connected to the bottom end of the top plate 1005. By sleeving the second slider 1009 on the lead screw 1008, when the lead screw 1008 rotates, the top plate 1005 can be driven to move, and then the cardboard can be pushed by the top plate 1005 to move, enabling the cutter 2004 to cut the cardboard at different positions.

[0032] Among them, a servo motor 1006 is installed on one side of the box body 1001, and the output end of the servo motor 1006 is in transmission connection with the lead screw 1008. By installing the servo motor 1006, when it works, the lead screw 1008 can be driven to rotate.

[0033] Among them, the cutting mechanism 200 includes a mounting frame 2001. The two sides of the bottom end of the mounting frame 2001 are respectively connected to the two sides of the upper end surface of the box body 1001. A lifting plate 2003 is slidably installed inside the mounting frame 2001. Cutters 2004 are installed at the bottom ends of the lifting plate 2003. A telescopic rod 2002 is inserted into the upper end of the mounting frame 2001, and the output end of the telescopic rod 2002 is connected to the top end of the lifting plate 2003. By installing the telescopic rod 2002, when it works, the lifting plate 2003 can be driven to lift, and then the cutters 2004 can move up and down to cut the cardboard.

[0034] Among them, a touch panel 1002 is installed on one side of the box body 1001, and the input-output end of the touch panel 1002 is in communication connection with the input-output ends of the telescopic rod 2002 and the servo motor 1006. By installing the touch panel 1002, it is convenient to control the operation of the device.

[0035] The specific usage method and function of this embodiment:

[0036] When using this product, the user adjusts the position of the top plate 1005 according to the cutting position of the carton, starts the servo motor 1006, and drives the screw rod 1008 to rotate. The second slider 1009 mounted on the screw rod 1008 drives the slidingly connected top plate 1005 to move. After moving to the appropriate position, the carton to be cut is placed on the upper end of the box body 1001, so that one end of the cardboard is against the top plate 1005. Then, the user starts the telescopic rod 2002 to drive the lifting plate 2003 to press down. The bottom end of the lifting plate 2003 is installed with a cutter 2004. As the cutter 2004 is pressed down, the cardboard is cut. When the cutter 2004 cuts the cardboard to the bottom, it will contact the pressure plate 3002 in the buffer groove 1010 and drive the pressure plate 3002 to press down. During the pressing process of the pressure plate 3002, the first slider 3007 will be driven to move to both sides of the slide bar 3009 through the connecting rod 3003 and squeeze the spring 3008, so as to use the contraction of the spring 3008 to buffer the cutter 2004. When the cutting is completed, the cutter rises slowly, and the pressure plate 3002 rises together with the cutter 2004 under the elastic force of the spring 3008, so as to avoid excessive pressure on the telescopic rod 2002 and damage to the cutter 2004.
