Description

Technical Field

[0001] The invention relates to the technical field of carton production, and in particular to a corrugated carton production device. Background Art

[0002] Corrugated paper boxes are a type of container widely used in the field of packaging and transportation. They are favored for their good protective performance, lightness and cost-effectiveness. They are mainly made of corrugated paper, which is a plate-like material made of noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into single corrugated paperboard and double corrugated paperboard. Corrugated paper has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled.

[0003] During the production process of corrugated paperboard, that is, during the corrugated paper forming period, the pulp needs to be scooped out and drained before being extruded into shape. In this process, the raw material transmission operation is particularly important. When the raw material is extruded by a roller, the raw material will be subjected to roller pressure from one side to the other, which will cause the raw material to be subjected to an inclined top pressure instead of a completely vertical downward top pressure. Therefore, obvious bevels are likely to appear on both sides of the rolled raw material, which will indirectly affect the quality of the corrugated paperboard. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that obvious bevels are easily formed on both sides of rolled raw materials, and to propose a corrugated paper box production equipment.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] In order to improve the quality of the raw materials, preferably, the opening and closing part includes two side plates fixedly connected to the lower end of the lifting plate, a double-headed threaded rod is rotatably installed between the two side plates, and the two pressing plates are threadedly connected to the two ends of the double-headed threaded rod, wherein a driving motor for driving the double-headed threaded rod to rotate is fixedly installed on one of the side plates.

[0008] In order to reduce the friction resistance between the pressing plate and the raw material, further, an inverted T-shaped vertical plate is fixedly connected to the middle of the lower end of the lifting plate, and the inverted T-shaped vertical plate is located between the two pressing plates. Pressing rollers are rotatably installed at the lower ends of the two pressing plates.

[0009] In order to improve the extrusion and drying control effect, further, two symmetrically arranged nozzles are provided at the lower end of the lifting plate, and the two nozzles are respectively fixedly connected to the outer walls of the two pressure plates, and the outer walls of the two nozzles are fixedly installed with downwardly inclined water push nozzles.

[0010] In order to automatically supply air to the nozzle, a telescopic airbag is further installed between the pressure plate and the side plate, and the telescopic airbag is fixedly connected to an intake pipe and an exhaust pipe connected thereto, and a one-way valve is fixedly installed in the intake pipe and the exhaust pipe, and the exhaust pipe is fixedly connected and connected to the nozzle.

[0011] In order to prevent wastewater from contaminating the raw materials located nearby, further, both sides of the lifting plate are fixedly connected with a device box with an opening facing downward, a water baffle is longitudinally slidably installed in the device box, and a spring is installed between the water baffle and the inner top of the device box.

[0012] In order to facilitate the collection of waste water, preferably, an upper water receiving box is installed on the mounting frame, the upper water receiving box is located below the hollow plate, an upper filter plate is installed inside the upper water receiving box, wherein a lower water receiving box located below the conveyor belt is fixedly installed at the bottom of the mounting frame, a lower filter plate is installed in the lower water receiving box, and a flushing portion is provided inside the conveyor belt.

[0013] In order to keep the conveyor belt clean, the flushing part further includes a flat tube fixedly mounted on a mounting frame, the lower end of the flat tube is provided with a recoil nozzle facing the inner wall of the belt and the lower water receiving box, wherein a pump body is fixedly mounted at the bottom of the upper water receiving box, the input end of the pump body extends into the upper water receiving box, and the output end of the pump body is connected to the flat tube via a connecting pipe.

[0014] In order to collect the waste water after flushing, further, the end of the suction pipe extends into the lower water receiving box, and the input end of the suction pipe is located below the lower filter plate.

[0015] In order to improve the filtering efficiency of the lower filter plate, further, the upper port of the lower water receiving box is provided with an annular groove, a rectangular frame is longitudinally slidably installed in the annular groove, and the device box is connected to the annular groove through an elastic tube.

[0016] Compared with the prior art, the present invention provides a corrugated box production equipment, which has the following beneficial effects:

[0017] 1. This corrugated box production equipment can complete the extrusion and drying of the raw materials by driving the pressing rollers to roll along the surface of the raw materials to both sides through two pressing plates. Since the two pressing rollers will roll from the middle of the raw materials to both sides, the extruded raw materials will be smoother and less prone to beveled edges, thus ensuring the quality of subsequent corrugated boxes.

[0018] 2. The corrugated box production equipment uses two pressing plates to press the telescopic airbag, and the nozzle will blow air to the surface of the raw material through the water-pushing nozzle. The moving pressing plate will also drive the nozzle and the water-pushing nozzle to move synchronously. The water-pushing nozzle will blow the squeezed water away from the pressing roller and the raw material along the surface of the raw material to prevent the squeezed water from being absorbed by the raw material again, thereby achieving the effect of improving the extrusion and drying control.

[0019] 3. The corrugated box production equipment draws water from the bottom of the upper water box through the pump body, and then transports it to the flat tube through the connecting pipe. The flat tube sprays water onto the inner wall of the conveyor belt through the recoil nozzle, and then the raw material impurities blocked in the water hole can be recoiled into the lower water box, thereby ensuring the cleanliness of the conveyor belt and facilitating the subsequent transportation and processing of the raw materials.

[0020] 4. The corrugated box production equipment drives the water baffles on both sides to press on the conveyor belt through the lifting plate. Therefore, when the raw materials are squeezed and dried, the generated water will be limited by the water baffles on both sides to prevent the water from flowing onto the raw materials on the side.

[0021] 5. The corrugated box production equipment sucks air from the bottom of the lower water receiving box through the suction pipe, and negative pressure is generated in the lower water receiving box, thereby improving the filtering efficiency of the lower filter plate.

[0022] 6. The corrugated box production equipment, when the water baffle is pressed into the device box, the device box will blow air to the annular groove through the elastic tube, and the rectangular frame in the annular groove will be lifted upward and pressed against the lower surface of the conveyor belt. Therefore, the negative pressure generated in the lower water receiving box will also act on the conveyor belt, making it easier for raw material debris in the water hole to fall off.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] Embodiment 1:

[0035] Reference Figure 1-Figure 8A corrugated paper box production equipment includes a mounting frame 1, and also includes: a conveyor belt 2, which is fixedly mounted on the mounting frame 1, and the conveyor belt 2 is mainly composed of a pulley, a belt and a driving device, wherein the belt of the conveyor belt 2 is provided with evenly distributed water holes 3, and a hollow plate 20 supporting the belt of the conveyor belt 2 is fixedly connected to the mounting frame 1, and the hollow plate 20 is used to support the pressure applied to the conveyor belt 2 when squeezing water; a top frame 4 fixedly connected to the top of the mounting frame 1, wherein a lifting device 5 is fixedly mounted on the lower end of the top frame 4, and the lifting device 5 is an electric telescopic rod, and the telescopic end of the lifting device 5 is fixedly connected to a lifting plate 6, and two symmetrically arranged pressing plates 8 are slidably mounted on the bottom of the lifting plate 6, and the lifting plate 6 is provided with an opening and closing part that drives the two pressing plates 8 to move closer or farther away from each other.

[0036] Specifically, when in use, the raw materials are placed on the conveyor belt 2 in sequence. When one piece of the raw material is placed directly below the top frame 4, the conveyor belt 2 is closed, and then the lifting plate 6 is driven downward by the lifting device 5 until the two pressing plates 8 are pressed on the raw material. At this time, the two pressing plates 8 are separated from each other by the opening and closing part, and the two pressing plates 8 will move to both sides along the surface of the raw material to complete the extrusion and drying of the raw material. Since the two pressing plates 8 will move from the middle of the raw material to both sides, the extruded raw material will be smoother and less prone to beveled edges, thereby ensuring the quality of subsequent corrugated paper boxes. After extrusion and drying, the pressing roller 9 is first driven away from the raw material by the lifting device 5, and then the two pressing plates 8 are driven close to each other and reset by the opening and closing part.

[0037] Embodiment 2:

[0038] Reference Figure 3-Figure 6 , which is basically the same as the first embodiment, and further discloses a specific implementation scheme of the opening and closing part.

[0039] The above-mentioned opening and closing part includes two side plates 12 fixedly connected to the lower end of the lifting plate 6, a double-headed threaded rod 10 is rotatably installed between the two side plates 12, and the two pressure plates 8 are respectively threadedly connected to the two ends of the double-headed threaded rod 10, wherein a driving motor 11 for driving the double-headed threaded rod 10 to rotate is fixedly installed on one of the side plates 12.

[0040] Specifically, when the two pressure plates 8 need to be moved closer to each other, the drive motor 11 is started, and the drive motor 11 will drive the double-headed threaded rod 10 to rotate, and the double-headed threaded rod 10 will drive the two pressure plates 8 away from each other. When the two pressure plates 8 need to be moved away from each other, the output shaft of the drive motor 11 can be reversed.

[0041] An inverted T-shaped vertical plate 7 is fixedly connected to the middle of the lower end of the above-mentioned lifting plate 6, and the inverted T-shaped vertical plate 7 is located between two pressing plates 8. Pressing rollers 9 are rotatably installed on the lower ends of the two pressing plates 8, and the pressing rollers 9 are tangent to the lower end surfaces of the inverted T-shaped vertical plates 7.

[0042] Specifically, when the lifting device 5 drives the lifting plate 6 to move downward, the lifting plate 6 will drive the inverted T-shaped vertical plate 7 and the two pressing rollers 9 to press on the raw material, and the pressing plate 8 that is away from each other will drive the two pressing rollers 9 to roll from the middle of the raw material to both sides, thereby reducing the movement resistance between the pressing plate 8 and the raw material, and the inverted T-shaped vertical plate 7 can press the middle of the raw material, so that the raw material is not easy to deflect, and the edges of the raw material are not easy to have beveled edges.

[0043] The lower end of the lifting plate 6 is provided with two symmetrically arranged nozzles 15, which are respectively fixedly connected to the outer walls of the two pressure plates 8, and the outer walls of the two nozzles 15 are fixedly installed with downwardly inclined water-pushing nozzles 16; a telescopic airbag 13 is installed between the pressure plate 8 and the side plate 12, and the telescopic airbag 13 is fixedly connected with an intake pipe 17 and an exhaust pipe 14 connected thereto, and a one-way valve is fixedly installed in the intake pipe 17 and the exhaust pipe 14, and the exhaust pipe 14 is fixedly connected and connected to the nozzle 15.

[0044] Specifically, when the two pressing plates 8 move away from each other, the two pressing plates 8 will also press the telescopic airbag 13, and the telescopic airbag 13 will blow air to the nozzle 15 through the exhaust pipe 14, and the nozzle 15 will blow air toward the surface of the raw material through the water-pushing nozzle 16. The moving pressing plate 8 will also drive the nozzle 15 and the water-pushing nozzle 16 to move synchronously, and the water-pushing nozzle 16 will blow the squeezed water away from the pressing roller 9 and the raw material along the surface of the raw material to prevent the squeezed water from being absorbed by the raw material again, thereby achieving the effect of enhancing the extrusion and drying control. When the two pressing plates 8 move away from each other, the telescopic airbag 13 will be stretched, and the telescopic airbag 13 will absorb external air through the suction pipe 17.

[0045] Embodiment three:

[0046] Reference Figure 3-Figure 8 , which is basically the same as Example 2, and further, a specific implementation plan for collecting wastewater is specifically added.

[0047] A device box 21 with an opening facing downward is fixedly connected to both sides of the lifting plate 6 . A water baffle 22 is longitudinally slidably installed in the device box 21 . A spring 23 is installed between the water baffle 22 and the inner top of the device box 21 .

[0048] Specifically, when the lifting plate 6 is pressed downward, the lifting plate 6 will also drive the water baffles 22 on both sides to press on the belt of the conveyor belt 2, that is, on both sides of the raw material, and the water baffles 22 that continue to move downward will be pushed back by the conveyor belt 2 into the device box 21 and compress the spring 23. Therefore, when the raw material is squeezed and dried, the generated water will be limited by the water baffles 22 on both sides to prevent the water from flowing onto the raw materials on the side. When the lifting plate 6 moves upward, the spring 23 will press the water baffle 22 downward, so that the water baffle 22 remains on the conveyor belt 2 for a fixed time. When the spring 23 is fully reset, the water baffle 22 will separate from the conveyor belt 2.

[0049] An upper water receiving box 18 for recycling waste water is installed on the above-mentioned mounting frame 1, and the upper water receiving box 18 is located below the hollow plate 20. An upper filter plate 19 for filtering raw material debris in the waste water is installed inside the upper water receiving box 18, wherein a lower water receiving box 24 located below the conveyor belt 2 is fixedly installed at the bottom of the mounting frame 1, and a lower filter plate 25 is installed in the lower water receiving box 24, and a flushing part is provided inside the belt of the conveyor belt 2; the flushing part includes a flat tube 30 fixedly installed on the mounting frame 1, and a recoil nozzle 31 facing the inner wall of the belt and the lower water receiving box 24 is installed at the lower end of the flat tube 30, wherein a pump body 29 is fixedly installed at the bottom of the upper water receiving box 18, and the pump body 29 is a water pump. The input end of the pump body 29 extends into the upper water receiving box 18, and the output end of the pump body 29 is connected to the flat tube 30 through a connecting pipe 32.

[0050] Specifically, the squeezed water will flow into the upper water box 18 through the water hole 3 and be filtered by the upper filter plate 19. The filtered water will be retained in the inner bottom of the upper water box 18, and the pump body 29 will extract the water at the bottom of the upper water box 18, and then transport it to the flat tube 30 through the connecting pipe 32. The flat tube 30 will spray water onto the inner wall of the conveyor belt 2 through the recoil nozzle 31, and then the raw material impurities blocked in the water hole 3 can be recoiled into the lower water box 24, thereby ensuring the cleanliness of the conveyor belt 2, and then facilitating the subsequent transportation and processing of the raw materials, and filtered by the lower filter plate 25. The filtered water will be stored in the inner bottom of the lower water box 24. In order to maintain the water level in the upper water box 18, the water in the lower water box 24 can be manually pumped back to the upper water box 18 on a regular basis.

[0051] Embodiment 4:

[0052] Reference Figure 3-Figure 5 as well as Figure 8 , which is basically the same as the third embodiment, and further, a specific implementation plan for improving the filtering efficiency of the lower filter plate 25 is specifically added.

[0053] The end of the air intake pipe 17 extends into the lower water receiving box 24, and the input end of the air intake pipe 17 is located below the lower filter plate 25. The upper end of the lower water receiving box 24 is provided with an annular groove 26, and a rectangular frame 27 is longitudinally slidably installed in the annular groove 26. The device box 21 and the annular groove 26 are connected by an elastic tube 28.

[0054] Specifically, when the two pressure plates 8 approach each other, the pressure plates 8 approaching each other will stretch the telescopic airbag 13, and the telescopic airbag 13 will suck air to the bottom of the lower water receiving box 24 through the suction pipe 17, and negative pressure will be generated in the lower water receiving box 24, thereby improving the filtration efficiency of the lower filter plate 25. When the water baffle 22 presses against the device box 21, the device box 21 will blow air to the annular groove 26 through the elastic tube 28, and the rectangular frame 27 in the annular groove 26 will be lifted upward and pressed against the lower surface of the conveyor belt 2. Therefore, the negative pressure generated in the lower water receiving box 24 will also act on the conveyor belt 2, making it easier for the raw material debris in the water hole 3 to fall off.

[0055] When the corrugated paper box production equipment is in use, the raw materials are placed on the conveyor belt 2 in sequence. When one of the raw materials is placed just below the top frame 4, the conveyor belt 2 is closed, and then the lifting device 5 drives the lifting plate 6 to move downward until the inverted T-shaped vertical plate 7 and the two pressing rollers 9 are pressed on the raw materials. At this time, the driving motor 11 is started, and the driving motor 11 will drive the double-headed threaded rod 10 to rotate, and the double-headed threaded rod 10 will drive the two pressing plates 8 to move away from each other, and the two pressing plates 8 will drive the pressing rollers 9 to roll to both sides along the surface of the raw materials, so that the extrusion and drying of the raw materials can be completed. Since the two pressing rollers 9 will roll from the middle of the raw materials to both sides, the extruded raw materials will be smoother and less prone to beveled edges, thereby ensuring the quality of subsequent corrugated paper boxes. After extrusion and drying, firstly, the pressing rollers 9 are driven away from the raw materials by the lifting device 5, and then the driving motor 11 is reversed, and the two pressing plates 8 will be reset close to each other again, and then another raw material is conveyed to the bottom of the top frame 4 by the conveyor belt 2 to carry out the extrusion and drying of the next raw material.

[0056] When the two pressing plates 8 move away from each other, the two pressing plates 8 will also press the telescopic airbag 13, and the telescopic airbag 13 will blow air to the nozzle 15 through the exhaust pipe 14, and the nozzle 15 will blow air toward the surface of the raw material through the water-pushing nozzle 16. The moving pressing plate 8 will also drive the nozzle 15 and the water-pushing nozzle 16 to move synchronously, and the water-pushing nozzle 16 will blow the squeezed water away from the pressing roller 9 and the raw material along the surface of the raw material to prevent the squeezed water from being absorbed by the raw material again, thereby achieving the effect of enhancing the extrusion and drying control. When the two pressing plates 8 move away from each other, the telescopic airbag 13 will be stretched, and the telescopic airbag 13 will absorb external air through the suction pipe 17.

[0057] The squeezed water will flow into the upper water box 18 through the water hole 3 and be filtered by the upper filter plate 19. The filtered water will be stored in the inner bottom of the upper water box 18, and the pump body 29 will extract the water from the inner bottom of the upper water box 18, and then transport it to the flat tube 30 through the connecting pipe 32. The flat tube 30 will spray water onto the inner wall of the conveyor belt 2 through the recoil nozzle 31, and then the raw material impurities blocked in the water hole 3 can be recoiled into the lower water box 24, thereby ensuring the cleanliness of the conveyor belt 2, and then facilitating the subsequent transportation and processing of the raw materials, and filtered by the lower filter plate 25. The filtered water will be stored in the inner bottom of the lower water box 24.

[0058] When the lifting plate 6 is pressed downward, the lifting plate 6 will also drive the water baffles 22 on both sides to press on the belt of the conveyor belt 2, that is, on both sides of the raw material, and the water baffles 22 that continue to move downward will be pushed back by the conveyor belt 2 into the device box 21 and compress the spring 23. Therefore, when the raw material is squeezed and dried, the generated water will be limited by the water baffles 22 on both sides to prevent water from flowing onto the raw materials on the side. When the lifting plate 6 moves upward, the spring 23 will press the water baffles 22 downward to keep the water baffles 22 on the conveyor belt 2 for a fixed time. When the spring 23 is completely reset, the water baffles 22 will be separated from the conveyor belt 2. When the water retaining plate 22 presses against the device box 21, the device box 21 blows air to the annular groove 26 through the elastic tube 28, and the rectangular frame 27 in the annular groove 26 is lifted upward and pressed against the lower surface of the conveyor belt 2. Therefore, the negative pressure generated in the lower water receiving box 24 will also act on the conveyor belt 2, making it easier for the raw material debris in the water hole 3 to fall off.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
