Description

Technical Field

[0001] The utility model relates to the technical field of foamed sheet cutting, in particular to a segmented cutting device for forming foamed sheet materials. Background Art

[0002] Foamed sheet materials are lightweight materials with buffer protection functions and are widely used in various packaging and protective products. Common foamed resin materials on the market include foamed polyurethane, foamed polystyrene, polyvinyl chloride, foamed polyethylene, and foamed polypropylene, etc. During the processing of foamed sheet materials, cutting equipment is often involved to cut them into segments.

[0003] According to the search, the Chinese patent document, publication number: CN218226923U, discloses a foamed sheet cutting device for hot cutting and forming of foamed sheet materials. By installing a servo motor, a rotating shaft, a flattening roller, and an anti-slip sleeve, the foamed sheet material is placed on the surface of the slide plate and moved closer to the flattening roller. At the same time, the servo motor is turned on, and the rotating shaft is driven to rotate by the servo motor, thereby driving the flattening roller to rotate. By using the anti-slip property of the anti-slip sleeve, the rotating flattening roller flattens the foamed sheet material, and at the same time, the foamed sheet material can be conveyed and sent into the protective box, thus ensuring the flatness of the foamed sheet material.

[0004] However, the above cutting device cannot perform equal-length segmented cutting on foamed sheet materials during actual use. The cutting length of the foamed sheet material completely needs to be adjusted manually, which has limitations in use. Summary of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the utility model provides a segmented cutting device for forming foamed sheet materials, which has the advantages of being able to perform equal-length cutting on foamed sheet materials and solves the above technical problems.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the utility model provides the following technical solutions: A segmented cutting device for forming foamed sheet materials includes a conveyor belt, a length measuring component, and a slitting component. There are two groups of the conveyor belts. Two T-shaped plates are installed between the two groups of conveyor belts. A lower roller shaft and an upper roller shaft are rotatably connected between the two T-shaped plates. A bearing seat is installed on the rotating shaft of the upper roller shaft. An adjusting rod is rotatably connected to the top of the bearing seat. The top end of the adjusting rod is fixedly connected to a handwheel. An ear block is fixedly connected to the outer surface of the T-shaped plate.

[0009] The length measuring component includes a side plate, a fixing block, an encoder, a length measuring wheel, a vertical rod and a spring. The fixing block is fixedly connected to the outer surface of the side plate. The encoder is installed on the top surface of the fixing block. The shaft end of the encoder is connected to the length measuring wheel. The lower surface of the base of the encoder is fixedly connected to the vertical rod. The spring is sleeved on the outer surface of the vertical rod.

[0010] The slitting component includes a mounting plate, a driving motor, a connecting plate, a connecting rod, a slider, a slide rail and a hot cutting knife. The driving motor is installed on the outer surface of the mounting plate. The connecting plate is installed on the output shaft of the driving motor. One end of the connecting plate is rotatably connected to the connecting rod. One end of the connecting rod is rotatably connected to the slider. The slide rail is installed on the outer surface of the mounting plate. The hot cutting knife is installed on the outer surface of the slider.

[0011] Preferably, a pulley is fixedly connected to one rotating shaft of the lower roller shaft. A pulley is also installed on the frame of one of the conveyor belts. A belt is connected between the two pulleys for transmission.

[0012] Through the above technical solutions, the conveyor belt is an existing device. Its principle is that the motor drives the roller to rotate, and the steel belt for conveying is sleeved on the outer surface of the roller. Therefore, the steel belt can rotate cyclically to convey the foamed sheet to be cut. One roller of the conveyor belt is connected to the lower roller shaft through a pulley and a belt. Therefore, the lower roller shaft can be driven. When the foamed sheet is conveyed from the front conveyor belt to the lower roller shaft, the lower roller shaft can continue to rotate to convey the foamed sheet to another conveyor belt.

[0013] Preferably, a screw hole is penetrated through the top surface of the ear block. An adjusting rod is threadedly connected in the screw hole. A chute is penetrated through the outer surface of the T-shaped plate. The rotating shaft of the upper roller shaft passes through the chute of the T-shaped plate and is connected to the bearing seat.

[0014] Through the above technical solutions, by rotating the handwheel, the adjusting rod can be driven to rotate. The adjusting rod feeds in the ear block. In this way, the adjusting rod can drive the bearing seat to move in the up and down directions. The bearing seat drives the upper roller shaft, thereby realizing the adjustment of the distance between the upper roller shaft and the lower roller shaft to adapt to the conveyance of foamed sheets of different thicknesses. When the foamed sheet is slit, the upper roller shaft and the lower roller shaft pause to clamp the foamed sheet so that it will not move during cutting.

[0015] Preferably, the side plate is installed on the frame of one of the conveyor belts through bolts. The shaft end of the encoder passes through the side plate and is connected to the length measuring wheel.

[0016] Through the above technical solution, when the foam sheet is transported by the conveyor belt at the front end and then moved to the conveyor belt at the rear end through the upper roller and the lower roller, the movement distance begins to be recorded when the foam sheet contacts the meter wheel. When the meter wheel rotates, the encoder generates a signal related to the rotation, and the controller can receive the signal and convert it into a corresponding linear movement distance, so that the distance moved by the foam sheet can be calculated; and because the spring is set to have a resistance force on the bottom end of the vertical rod, the meter wheel can fit on the steel belt of the conveyor belt under normal conditions, and foam sheets of different thicknesses can also contact the meter wheel.

[0017] Preferably, the encoder is connected to a controller via a wire, and the controller is mounted on a frame of one of the conveyor belts.

[0018] Through the above technical solution, the controller is used to connect the encoder, the drive motor and the conveyor motor of the conveyor belt. The cutting length of the foam sheet is set through the controller. When the meter wheel cooperates with the encoder to measure the distance the foam sheet moves to reach the set cutting length, the conveyor belt stops rotating and the slitting assembly starts to cut the foam sheet. It is worth noting that when setting the cutting length of the foam sheet, the front end of the foam sheet needs to be aligned with the hot cutting knife, and then the meter wheel cooperates with the encoder to start measuring the foam sheet.

[0019] Preferably, the mounting plate, the connecting plate, the connecting rod, the sliding block and the sliding rail are each provided in two groups, and a transmission rod is fixedly connected between the two connecting plates.

[0020] Through the above technical solution, when the foam sheet is measured to the set length, the conveyor belt stops conveying, and then the driving motor starts to drive the connecting plate to rotate, the connecting plate drives the connecting rod, the connecting rod drives the slider to move on the slide rail, and the slider drives the hot cutter to move downward to cut the foam sheet, thereby achieving equal length cutting of the foam sheet. The hot cutter is an existing device, which has a heating component inside that can heat the external blade to facilitate cutting of the foam sheet.

[0021] Compared with the prior art, the utility model provides a foam sheet forming segment cutting device, which has the following beneficial effects:

[0022] 1. The utility model is provided with components such as a meter wheel, an encoder and a controller. When the front end of the foam sheet is aligned with the hot cutter, the meter wheel starts to measure the foam sheet. When the meter wheel rotates, the encoder generates a signal related to the rotation. The controller can receive the signal and convert it into a corresponding linear moving distance, so that the distance moved by the foam sheet can be calculated. When the foam sheet moves a set distance, the conveyor belt stops and the slitting assembly cuts the foam sheet, so that the foam sheet can be divided into equal length segments.

[0023] 2. After the foamed sheet is measured to the set length, the conveyor belt stops running, and then the drive motor starts to drive the connecting plate to rotate. The connecting plate drives the connecting rod, and the connecting rod drives the slider to move on the slide rail. The slider drives the hot cutter to move downward to cut the foamed sheet, thus realizing the equal-length cutting of the foamed sheet. Description of the Drawings

[0033] The slitting component 3 includes a mounting plate 31, a driving motor 32, a connecting plate 33, a connecting rod 34, a slider 35, a slide rail 36 and a hot cutting knife 37. The driving motor 32 is installed on the outer surface of the mounting plate 31. The connecting plate 33 is installed on the output shaft of the driving motor 32.

The slide rail 36 is installed on the outer surface of the mounting plate 31. The hot cutting knife 37 is installed on the outer surface of the slider 35.

[0034] Specifically, a pulley is fixedly connected to a rotating shaft of the lower roller shaft 5. A pulley is also installed on the frame of one of the conveyor belts 1. A belt is drivingly connected between the two pulleys. The advantage is that the conveyor belt 1 is an existing device. Its principle is that the motor drives the roller to rotate. A steel belt for conveying is sleeved on the outer surface of the roller. So the steel belt can rotate cyclically to convey the foamed sheet to be cut. And one roller of the conveyor belt 1 is connected to the lower roller shaft 5 through the cooperation of the pulley and the belt. So the lower roller shaft 5 can be driven. When the foamed sheet is conveyed from the front conveyor belt 1 to the lower roller shaft 5, the lower roller shaft 5 can continue to rotate to convey the foamed sheet to another conveyor belt 1.

[0035] Specifically, a screw hole is penetrated and opened on the top surface of the ear block 10. The adjusting rod 8 is threadedly connected in the screw hole. A chute is penetrated and opened on the outer surface of the T-shaped plate 4. The rotating shaft of the upper roller shaft 6 passes through the chute of the T-shaped plate 4 and is connected to the bearing seat 7. The advantage is that by rotating the handwheel 9, the adjusting rod 8 can be driven to rotate. The adjusting rod 8 feeds in the ear block 10. In this way, the adjusting rod 8 can drive the bearing seat 7 to move in the up and down direction. The bearing seat 7 drives the upper roller shaft 6. Furthermore, the distance between the upper roller shaft 6 and the lower roller shaft 5 can be adjusted to adapt to conveying foamed sheets of different thicknesses. When the foamed sheet is slit, the upper roller shaft 6 and the lower roller shaft 5 pause to move and can clamp the foamed sheet so that it will not move during cutting.

[0036] Specifically, the side plate 21 is installed on the frame of one of the conveyor belts 1 by bolts, and the shaft end of the encoder 23 passes through the side plate 21 and is connected to the meter wheel 24. The advantage is that when the foam sheet is transported by the front conveyor belt 1 and then transported by the upper roller 6 and the lower roller 5 and moved to the rear conveyor belt 1, the foam sheet starts to record the movement distance after contacting the meter wheel 24. When the meter wheel 24 rotates, the encoder 23 generates a signal related to the rotation, and the controller 11 can receive the signal and convert it into the corresponding linear movement distance, so that the distance moved by the foam sheet can be calculated; and because the spring 26 is set to have a resistance force on the bottom end of the vertical rod 25, the meter wheel 24 can fit on the steel belt of the conveyor belt 1 under normal conditions, and foam sheets of different thicknesses can also contact the meter wheel 24.

[0037] Specifically, the encoder 23 is connected to the controller 11 through a wire, and the controller 11 is installed on the frame of one of the conveyor belts 1. The advantage is that the controller 11 is used to connect the encoder 23, the drive motor 32 and the conveying motor of the conveyor belt 1, and the cutting length of the foam sheet is set by the controller 11. When the meter wheel 24 cooperates with the encoder 23 to measure the distance moved by the foam sheet to reach the set cutting length, the conveyor belt 1 stops rotating, and the slitting component 3 starts to cut the foam sheet. It is worth noting that when setting the cutting length of the foam sheet, the front end of the foam sheet needs to be aligned with the hot cutting knife 37, and then the meter wheel 24 cooperates with the encoder 23 to start measuring the foam sheet.

[0038] Specifically, two groups of mounting plates 31, connecting plates 33, connecting rods 34, sliders 35 and slide rails 36 are provided, and a transmission rod 12 is fixedly connected between two connecting plates 33. The advantage is that when the foam sheet is measured to a set length, the conveyor belt 1 stops conveying, and then the driving motor 32 starts to drive the connecting plate 33 to rotate, the connecting plate 33 drives the connecting rod 34, and the connecting rod 34 drives the slider 35 to move on the slide rail 36, and the slider 35 drives the hot cutter 37 to move downward to cut the foam sheet, so that the foam sheet is cut in equal length. The hot cutter 37 is an existing device, and a heating component inside it can heat the external blade to facilitate cutting of the foam sheet.

[0039] In use, first, the foamed sheet is conveyed by the front conveyor belt 1, and then the foamed sheet is continuously conveyed to the rear conveyor belt 1 by the cooperation of the upper roller shaft 6 and the lower roller shaft 5. The adjusting rod 8 can be driven to rotate by turning the handwheel 9. The adjusting rod 8 feeds in the ear block 10. In this way, the adjusting rod 8 can drive the bearing seat 7 to move in the up and down direction. The bearing seat 7 drives the upper roller shaft 6, so as to adjust the distance between the upper roller shaft 6 and the lower roller shaft 5 to adapt to the conveyance of foamed sheets of different thicknesses. After the foremost end of the foamed sheet moves to the position of the hot cutting knife 37, the cutting length is set by the controller 11. Finally, the counting wheel 24 cooperates with the encoder 23 to start counting the length of the foamed sheet. When the set value is reached, the controller 11 stops the conveyor belt 1, and then the driving motor 32 starts to drive the connecting plate 33 to rotate. The connecting plate 33 drives the connecting rod 34, and the connecting rod 34 drives the slider 35 to move on the slide rail 36. The slider 35 drives the hot cutting knife 37 to move downward to cut the foamed sheet.
