Description

Technical Field

[0001] The utility model relates to the technical field of carton production equipment, in particular to a continuous die-cutting machine for cartons based on carton production. Background Art

[0002] Cartons are a common packaging material, usually used for transporting and storing various items. They can be made of different materials, such as cardboard, corrugated paper, etc. Cartons have many advantages, such as being lightweight, durable, recyclable, etc., and their cost is relatively low, so they are widely used in many industries.

[0003] At present, during the processing of cartons, it is often necessary to cut a C-shaped opening on both sides of the carton so that the handler can easily hold the carton during handling. Due to financial constraints in existing small carton production factories, the carton opening die-cutting equipment is relatively simple. During the opening die-cutting process, manual assistance is required to hold the carton to ensure that the carton can be stably die-cut. However, the manual assistance process is rather cumbersome and boring, which not only affects the comfort of the staff but also the convenience and efficiency of carton die-cutting processing.

[0004] Therefore, a continuous die-cutting machine for cartons based on carton production is proposed to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a continuous die-cutting machine for cartons based on carton production in view of the above problems.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A continuous die-cutting machine for cartons based on carton production includes a conveyor main body. Two groups of belt grooves are jointly opened on the outer walls of the two conveying rollers of the conveyor main body. A conveyor belt is sleeved on the groove walls of each group of belt grooves. A U-shaped platform is fixedly connected inside the conveyor main body. A U-shaped frame is fixedly connected to the outer wall of the conveyor main body. Two through holes are opened on the outer wall of the U-shaped frame, and the hole walls of the through holes are connected with a lead screw nut through rolling bearings. A reciprocating lead screw is threadedly sleeved inside the lead screw nut. The bottom end of the reciprocating lead screw is fixedly connected with a connecting block. A limiting sleeve is movably sleeved on the outer wall of the connecting block. The top end of the limiting sleeve is fixedly connected to the upper surface of the U-shaped frame. A C-shaped die-cutting tool is fixedly connected to the lower surface of the connecting block. A stabilizing mechanism is fixedly connected to the lower surface of the connecting block. A driving mechanism is fixedly connected to the outer wall of the U-shaped frame.

[0008] Preferably, the stabilizing mechanism includes telescopic rods fixedly connected to the lower surface of the connecting block. The bottom ends of the two telescopic rods are jointly fixedly connected with a pressing frame. A return spring is sleeved on the rod walls of the telescopic rods. The two ends of the return spring are respectively fixedly connected to the lower surface of the connecting block and the upper surface of the pressing frame.

[0009] Preferably, the driving mechanism includes a fixing plate fixedly connected to the outer wall of the U-shaped frame. A driving motor is fixedly connected to the outer wall of the fixing plate. The output end of the driving motor is fixedly connected to a driving sprocket. Driven sprockets are fixedly sleeved on the outer walls of the two lead screw nuts. The driving sprocket and the two driven sprockets are jointly sleeved with a transmission chain.

[0010] Preferably, the driving sprocket and the two driven sprockets are distributed in an isosceles triangle on the same horizontal plane.

[0011] Preferably, grooves are formed in the outer wall of the conveyor belt, and an anti-slip fluff layer is fixedly connected to the groove walls of the grooves. A plurality of anti-slip rubber ridges are fixedly connected to the inner wall of the conveyor belt.

[0012] Preferably, the upper surface of the U-shaped table is on the same horizontal plane as the upper surface of the conveyor belt.

[0013] Compared with the prior art, the utility model provides a continuous die-cutting machine for cartons based on carton production, which has the following beneficial effects:

[0014] 1. For the continuous die-cutting machine for cartons based on carton production, through the arranged stabilizing mechanism, C-shaped die-cutting tool and U-shaped table, when a small carton factory performs C-shaped opening operation on a carton, first, the carton is conveyed to the conveyor belt by the conveying line, and the carton opening position is transferred to the U-shaped table, and then the driving mechanism is started. The speed of the driving mechanism matches the speed of the conveyor body. Then, the lead screw nut moves the reciprocating lead screw downward. The reciprocating lead screw pushes the C-shaped die-cutting tool downward through the connecting block to perform carton opening die-cutting. Moreover, before die-cutting, the pressing frame of the stabilizing mechanism first contacts the carton. As the downward movement distance of the connecting block increases, the telescopic rod is compressed and drives the return spring to be compressed. The elastic force of the return spring pushes the pressing frame to tightly press the carton, ensuring the stability of the carton when it is die-cut and opened. Moreover, in the initial stage of the upward movement of the C-shaped die-cutting tool, the pressing frame is still pressed by the return spring to press the carton, avoiding the deviation of the carton during the upward movement of the C-shaped die-cutting tool, thereby ensuring that the carton opening is not damaged by the C-shaped die-cutting tool and ensuring the safety of carton die-cutting processing. This mechanism enables the die-cutting machine of the small carton processing factory to have the function of stabilizing the carton, ensuring the stability of carton opening die-cutting, thereby improving the convenience and efficiency of carton die-cutting processing and the comfort of the staff's work.

[0015] 2. For the continuous die-cutting machine for cartons based on carton production, through the arranged driving mechanism, by controlling the switch to control the rotation speed of the driving motor, the driving motor drives the rotation speed of the two lead screw nuts through the driving sprocket, transmission chain and driven sprockets, thereby controlling the up and down movement speed of the reciprocating lead screw, and thus improving the processing speed of the C-shaped die-cutting tool. This mechanism enables the die-cutting machine to have the function of continuously adjusting the die-cutting speed.

[0016] The parts not involved in this device are the same as the prior art or can be implemented using the prior art. This utility model enables the die-cutting machine in a small cardboard box processing factory to have the function of stabilizing the cardboard box, ensuring the stability of die-cutting the opening of the cardboard box. Moreover, the die-cutting machine also has the function of continuously adjusting the die-cutting speed, thereby improving the convenience and efficiency of cardboard box die-cutting processing, as well as enhancing the comfort of the staff's work.

Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments.

[0023] Refer to Figures 1-4, A continuous die-cutting machine for producing cardboard boxes based on cardboard boxes, including a conveyor main body 1. Two sets of grooves are commonly opened on the outer walls of the two conveying rollers of the conveyor main body 1. A conveyor belt 2 is sleeved on the groove walls of each set of grooves. A groove is opened on the outer wall of the conveyor belt 2, and an anti-slip fluff layer 12 is fixedly connected to the groove wall of the groove. A plurality of anti-slip rubber ridges 13 are fixedly connected to the inner wall of the conveyor belt 2. The anti-slip rubber ridges 13 can cooperate with the anti-slip fluff layer 12 to ensure the stability of the cardboard box conveyed by the conveyor belt 2 and avoid the situation of slipping during disassembly. A U-shaped platform 3 is fixedly connected inside the conveyor main body 1. A U-shaped frame 4 is fixedly connected to the outer wall of the conveyor main body 1. Two through holes are opened on the outer wall of the U-shaped frame 4, and a lead screw nut 5 is connected to the hole wall of the through hole through a rolling bearing. A reciprocating lead screw 6 is threadedly sleeved inside the lead screw nut 5. The bottom end of the reciprocating lead screw 6 is fixedly connected to a connecting block 7. A limiting sleeve 10 is movably sleeved on the outer wall of the connecting block 7. The top end of the limiting sleeve 10 is fixedly connected to the upper surface of the U-shaped frame 4. A C-shaped die-cutting tool 11 is fixedly connected to the lower surface of the connecting block 7.

[0024] A stabilizing mechanism 8 is fixedly connected to the lower surface of the connecting block 7. The stabilizing mechanism 8 includes a telescopic rod 81 fixedly connected to the lower surface of the connecting block 7. The bottom ends of the two telescopic rods 81 are commonly fixedly connected to a pressing frame 82. A return spring 83 is sleeved on the rod wall of the telescopic rod 81. The two ends of the return spring 83 are respectively fixedly connected to the lower surface of the connecting block 7 and the upper surface of the pressing frame 82. This mechanism enables the die-cutting machine in small cardboard box processing factories to have the function of stabilizing the cardboard box, ensuring the stability of die-cutting the opening of the cardboard box, thereby improving the convenience and efficiency of cardboard box die-cutting processing, and improving the comfort of the staff's work.

[0025] A driving mechanism 9 is fixedly connected to the outer wall of the U-shaped frame 4. The driving mechanism 9 includes a fixing plate 91 fixedly connected to the outer wall of the U-shaped frame 4. A driving motor 92 is fixedly connected to the outer wall of the fixing plate 91. The output end of the driving motor 92 is fixedly connected to a driving sprocket 93. Driven sprockets 94 are fixedly sleeved on the outer walls of the two lead screw nuts 5. The driving sprocket 93 and the two driven sprockets 94 are commonly sleeved with a transmission chain 95. The driving sprocket 93 and the two driven sprockets 94 are distributed in an isosceles triangle on the same horizontal plane, thereby ensuring the reliability of the transmission of the driving sprocket 93.

[0026] The upper surface of the U-shaped platform 3 is on the same horizontal plane as the upper surface of the conveyor belt 2, thereby ensuring that the cardboard box can be laid flat on the U-shaped platform 3 for die-cutting and avoiding the situation of the cardboard box being bent and deformed due to suspension. The driving motor 92 is electrically connected to an external power supply through a control switch. This electrical connection is a prior art and belongs to the common technical means of those skilled in the art, so it will not be elaborated here.

[0027] In the present utility model, when a small cardboard box factory performs a C-shaped opening operation on a cardboard box, first, the cardboard box is conveyed by a conveyor line to conveyor belt 2, and the cardboard box punching position is transferred to U-shaped table 3. Then, drive mechanism 9 is started, and the rotation speed of drive motor 92 is controlled through a control switch. Drive motor 92 drives the rotation speed of two lead screw nuts 5 through driving sprocket 93, transmission chain 95, and driven sprocket 94, thereby controlling the up and down movement speed of reciprocating lead screw 6, and thus increasing the processing speed of C-shaped die-cutting tool 11. The speed of drive mechanism 9 is matched with the conveying speed of conveyor main body 1. Then, lead screw nut 5 causes reciprocating lead screw 6 to move downward. Reciprocating lead screw 6 pushes C-shaped die-cutting tool 11 downward through connecting block 7 to perform cardboard box punching and die-cutting. Moreover, before die-cutting, pressing frame 82 of stabilizing mechanism 8 first contacts the cardboard box. As the downward movement distance of connecting block 7 increases, telescopic rod 81 is compressed, driving the compression of return spring 83. The elastic force of return spring 83 pushes pressing frame 82 to tightly press the cardboard box, ensuring the stability of the cardboard box during die-cutting and opening. Moreover, in the initial stage of the upward movement of C-shaped die-cutting tool 11, pressing frame 82 is still pressed by return spring 83 and also presses the cardboard box, preventing the cardboard box from shifting during the upward movement of C-shaped die-cutting tool 11, thus ensuring that the cardboard box opening is not damaged by C-shaped die-cutting tool 11 and guaranteeing the safety of cardboard box die-cutting processing. This mechanism enables the die-cutting machine of a small cardboard box processing factory to have the function of stabilizing the cardboard box, ensuring the stability of cardboard box opening die-cutting. Moreover, the die-cutting machine also has the function of continuously adjusting the die-cutting speed, thereby improving the convenience and efficiency of cardboard box die-cutting processing, as well as the comfort of the staff's work.

[0028] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
