Description

Technical Field

[0001] The utility model belongs to the technical field of trimming machines, in particular to a trimming machine for processing paper boxes. Background Art

[0002] The main raw materials for corrugated paper boxes include corrugated cardboard, face paper, and glue. Corrugated cardboard consists of two layers of face paper with a layer of corrugated core paper sandwiched between them. Depending on the thickness of the corrugated core paper and the shape of the corrugations, it can be made into four different thicknesses of corrugated cardboard: B-type, C-type, E-type, and F-type. Face paper is the surface material of the corrugated cardboard. Common face paper includes kraft paper, white cardboard, cowhide cardboard, coated paper, and other materials. When processing corrugated paper boxes, the cardboard needs to be trimmed to remove burrs or cut uneven edges. However, in the existing technology, a certain amount of dust is generated when cutting the cardboard. This dust easily flies into the air, causing a decrease in the air quality of the working environment. At the same time, the collection of the waste generated by cutting is also inconvenient. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a trimming machine for paper box processing, which can automatically collect the powder generated during the cutting process and the waste generated after cutting, and avoid the problem of powder splashing in the working environment causing dust and difficulty in cleaning.

[0004] The top of the machine table is provided with a conveyor belt, and the top of the machine table is provided with a trimming and cutting device, and the top of the machine table is downwardly penetrated by a cutting groove and a waste output trough, and the bottom of the machine table is provided with a collection box through a connecting rod, and a collection drawer is inserted into the collection box and installed, and a partition is installed inside the collection drawer. Two sets of adjustment and positioning devices are installed on the top of the machine table, and the adjustment positioning device includes a second mounting bracket installed on the top of the machine table, and a screw rod and an adjusting slide rod are threadedly installed between the side surfaces of the second mounting bracket. A screw stepper motor is installed on one side of the second mounting bracket, and the screw stepper motor is threadedly connected to the screw rod. One end of the screw rod and the adjusting slide rod is connected to the mounting plate, and the side surface of the mounting plate is rotatably connected to a limited roller. The bottom of the cutting groove is provided with a suction cover, and the bottom of the suction cover is connected to the negative pressure fan.

[0005] The beneficial effects of the utility model are as follows: when the device is used, the operation of the screw stepper motors on the two sets of adjustment and positioning devices is controlled according to the width of the corrugated cardboard for carton processing to be trimmed, and the screw stepper motor drives the screw to drive the mounting plate to adjust the position horizontally under the cooperation of the adjusting slide rod, thereby changing the spacing between the mounting plates of the two sets of adjustment and positioning devices, so that the distance between the two sets of limiting rollers is the same as the width of the cardboard, and at the same time, the positions of the two sets of mounting plates can be adjusted according to the required cutting length, thereby adjusting the position of the cardboard so that the trimming line of the cardboard can be aligned with the cutter disc. When trimming the cardboard, the servo motor is first controlled to drive the cutter disc mounting seat and the cutter disc to rotate, and the support plate to be trimmed is placed between the two sets of adjustment and positioning devices from one end of the conveyor belt, so that the limiting rollers on the adjustment and positioning device contact and limit the two edges of the cardboard, thereby avoiding deflection during the conveying process. At the same time, the cylinder can drive the spring telescopic rod to descend, so that the pressure wheel is pressed tightly against the top of the cardboard, and the compression force generated by the compression of the spring telescopic rod makes the cardboard close to the top of the conveyor belt, thereby avoiding the situation of warping and flipping during the cutting process.

[0006] The cardboard is cut and trimmed by the rotating knife disc, and at the same time, the negative pressure fan runs through the suction hood set at the bottom of the cutting groove to suck the powder generated by the cutting downward and discharge it through the first conveying pipe to the collection box. The collection drawer is located in the space on one side of the partition. The air flow is discharged through the exhaust port and prevented from overflowing by the filter. The waste after cutting falls into the waste output trough and falls into the space on the other side of the partition in the collection drawer through the second conveying pipe, thereby realizing the automatic collection of the powder generated during the cutting process and the waste generated after cutting, and avoiding the problem of dust caused by powder splashing and difficult cleaning in the working environment.

[0007] To cut the cardboard:

[0008] As a further improvement of the above technical solution: the trimming and cutting device includes a first mounting bracket fixed on the top of the machine, a motor mounting seat is installed on the inner side of the first mounting bracket, a servo motor is installed on one side of the motor mounting seat, the output end of the servo motor is connected to the cutter disc mounting seat, and a cutter disc is screwed to one side of the cutter disc mounting seat.

[0009] The beneficial effect of this improvement is that the edge of the cardboard can be cut by controlling the servo motor to drive the cutter disc mounting seat and the cutter disc to rotate.

[0010] To exhaust the airflow:

[0011] As a further improvement of the above technical solution: an air outlet is passed through one side panel of the collection box and the collection drawer, and a filter is installed on the inner side of the air outlet of the collection drawer.

[0012] The beneficial effect of this improvement is that the air flow entering the collection drawer is discharged through the exhaust port and prevents powder from overflowing through the filter.

Two sets of adjustment and positioning devices 11 are installed on the top of the machine platform 1, and the adjustment and positioning device 11 includes a plurality of adjustment and positioning devices installed on the machine platform 1. A second mounting bracket 13 at the top, a screw rod 15 and an adjustment slide rod 16 are threadedly installed between the two side surfaces of the second mounting bracket 13, a screw stepper motor 14 is installed on one side of the second mounting bracket 13, the screw stepper motor 14 is threadedly connected to the screw rod 15, one end of the screw rod 15 and the adjustment slide rod 16 are connected to the mounting plate 17, the side of the mounting plate 17 is rotatably connected to the limiting roller 18, a suction hood 21 is installed at the bottom of the cutting groove 9, and the bottom of the suction hood 21 is connected to the negative pressure fan 22.

[0028] When the device is used, the operation of the screw stepper motor 14 on the two sets of adjustment and positioning devices 11 is controlled according to the width of the corrugated cardboard for paper box processing to be trimmed. The screw stepper motor 14 drives the screw 15 to drive the mounting plate 17 to adjust the position horizontally in cooperation with the adjustment slide 16, thereby changing the spacing between the mounting plates 17 of the two sets of adjustment and positioning devices 11, so that the distance between the two sets of limiting rollers 18 is the same as the width of the cardboard. At the same time, the position of the two sets of mounting plates 17 can be adjusted according to the required cutting length, thereby adjusting the position of the cardboard so that the trimming line of the cardboard can be aligned with the knife disc 8. When trimming the cardboard, first control the servo motor 6 to drive the cutter disc mounting seat 7 and the cutter disc 8 to rotate, and put the support plate to be trimmed from one end of the conveyor belt 2 into the space between the two sets of adjustment and positioning devices 11, so that the limiting rollers 18 on the adjustment and positioning devices 11 contact the two sides of the cardboard and limit it to avoid deflection during the conveyance process. At the same time, the cylinder 12 can drive the spring telescopic rod 19 to descend, so that the pressure wheel 20 is pressed tightly against the top of the cardboard. The compression of the spring telescopic rod 19 generates an extrusion force to make the cardboard close to the top of the conveyor belt 2, avoiding the situation of warping and flipping during the cutting process.

[0029] The cardboard is cut and trimmed by the rotating knife disc 8, and at the same time, the negative pressure fan 22 runs through the suction cover 21 set at the bottom of the cutting groove 9 to suck the powder generated by the cutting downward and discharge it through the first conveying pipe 23 to the collection box 25. The collection drawer 26 is located in the space on the side of the partition 27. The air flow is discharged through the exhaust port 28 and prevented from overflowing by the filter 29. The waste after cutting falls into the waste output trough 10 and falls into the space on the other side of the partition 27 in the collection drawer 26 through the second conveying pipe 24, thereby realizing the automatic collection of the powder generated during the cutting process and the waste generated after cutting, and avoiding the problem of dust caused by powder splashing in the working environment and difficulty in cleaning.

[0030] The trimming and cutting device 3 includes a first mounting bracket 4 fixed on the top of the machine 1, a motor mounting seat 5 is installed on the inner side of the first mounting bracket 4, a servo motor 6 is installed on one side of the motor mounting seat 5, the output end of the servo motor 6 is connected to the cutter disc mounting seat 7, and a cutter disc 8 is screwed to one side of the cutter disc mounting seat 7.

[0031] The servo motor 6 is controlled to drive the cutter disc mounting seat 7 and the cutter disc 8 to rotate, so that the edge of the cardboard can be cut.

[0032] An air outlet 28 is formed through one side panel of the collection box 25 and the collection drawer 26 , and a filter 29 is installed inside the air outlet 28 of the collection drawer 26 .

[0033] The air flow into the collection drawer 26 is discharged through the exhaust port 28 and passes through the filter 29 to prevent powder from overflowing.

[0034] A cylinder 12 is installed on the top of the mounting plate 17 , a spring telescopic rod 19 is installed at the bottom end of the piston rod of the cylinder 12 , and a pressure wheel 20 is installed on a rotating roller on one side of the bottom of the spring telescopic rod 19 .

[0035] The cylinder 12 can drive the spring telescopic rod 19 to descend, so that the pressure wheel 20 is pressed against the top of the cardboard. The compression of the spring telescopic rod 19 generates an extrusion force to make the cardboard close to the top of the conveyor belt 2, avoiding the situation of warping and flipping during the cutting process.

[0036] The bottom of the negative pressure fan 22 is connected to a first conveying pipe 23 , the bottom of the first conveying pipe 23 is connected to a collecting box 25 , and a second conveying pipe 24 is connected between the bottom of the waste output trough 10 and the collecting box 25 .

[0037] The first conveying pipe 23 and the second conveying pipe 24 are used to convey dust and waste materials into the collection drawer 26 respectively.

[0038] The working principle and use process of the present invention are as follows: when the device is used, the screw stepper motor 14 on the two sets of adjusting and positioning devices 11 is controlled to operate according to the width of the corrugated cardboard for processing the paper box to be trimmed. The screw stepper motor 14 drives the screw 15 to drive the mounting plate 17 to adjust the position horizontally under the cooperation of the adjusting slide 16, thereby changing the spacing between the mounting plates 17 of the two sets of adjusting and positioning devices 11, so that the distance between the two sets of limiting rollers 18 is the same as the width of the cardboard. At the same time, the positions of the two sets of mounting plates 17 can be adjusted according to the required cutting length, thereby adjusting the position of the cardboard so that the trimming line of the cardboard can be aligned with the knife disc 8. When trimming the cardboard, the servo motor 6 is first controlled to drive the knife disc mounting seat 7 and the knife disc 8 to rotate, and the support plate to be trimmed is placed between the two sets of adjusting and positioning devices 11 from one end of the conveyor belt 2, so that the limiting rollers 18 on the adjusting and positioning device 11 contact the two edges of the cardboard and limit it to avoid deflection during the transmission process. At the same time, the cylinder 12 can drive the spring telescopic rod 1 9 descends, causing the pressing wheel 20 to press tightly against the top of the cardboard. The spring telescopic rod 19 is compressed to generate an extrusion force to make the cardboard close to the top of the conveyor belt 2, thereby preventing it from tilting or turning over during the cutting process. When the cardboard is conveyed by the conveyor belt 2 to the position where the cutter disc 8 is located, the cardboard is cut and trimmed by the rotating cutter disc 8. At the same time, the negative pressure fan 22 runs through the suction cover 21 set at the bottom of the cutting groove 9 to suck the powder generated by the cutting downward and discharge it through the first conveying pipe 23 to the collection box 25. The collection drawer 26 is located on one side of the partition 27. The air flow is discharged through the exhaust port 28 and passes through the filter screen 29 to prevent the powder from overflowing. The waste after cutting falls into the waste output trough 10 and falls into the collection drawer 26 on the other side of the partition 27 through the second conveying pipe 24, thereby realizing the automatic collection of the powder generated during the cutting process and the waste generated after cutting, and avoiding the problem of dust caused by powder splashing and difficult cleaning in the working environment. The waste and powder in it can be cleaned by pulling out the collection drawer 26.
