Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of straw paper production, and particularly relates to a straw paper production equipment and a production process thereof. BACKGROUND

[0002] The straw paper production equipment plays an important role in the modern environmental protection industry, and the production demand of paper straws is increasing day by day. The produced paper straws are not only widely used in food packaging, catering and other industries, but also have important significance in promoting green and sustainable development. However, in the production process of paper straws, the cutting link is one of the key processes, which directly affects the quality and production efficiency of the finished paper straws.

[0003] The traditional cutting device of paper straws usually adopts a rigid straight cutting method, and the blade directly cuts the straw paper quickly. Although this cutting method can meet the basic production demand, it has the following problems: the instantaneous tearing of straw paper fibers during cutting will cause a large vibration amplitude and a high burr rate of the cutting edge, which affects the appearance and use performance of the paper straws. In addition, the blade angle of the cutting device is fixed, and it cannot realize the diversified cutting demand of flat mouth at one end and bevel cutting at the other end, which increases the complexity and cost of subsequent processing. At the same time, when adjusting the length of the paper straws, the existing cutting device often needs to be manually adjusted or has a complex mechanical structure, which leads to low production efficiency and is difficult to meet the needs of large-scale production.

[0004] Patent CN114434540A discloses an automatic production equipment and production method for environment-friendly paper straws. The pipe body production mechanism is fixedly arranged on the left side of the upper end of the installation platform, the segmentation mechanism is fixedly arranged on the right side of the upper end of the installation platform, and the cutting mechanism is arranged on the right side of the installation platform. The pipe body production mechanism is used to produce pipe bodies and transport the pipe bodies to the right. The segmentation mechanism quickly segments the pipe bodies by rotating the cutter along the pipe body transportation direction. The cutting mechanism is used to align and cut the straw segments into straws. However, the production equipment in the patent has the following shortcomings: the production equipment directly cuts the paper straws during cutting, and the burr rate of the cutting edge is high. The production equipment needs to segment the paper straws first and then cut them again, which is complicated. Not only a lot of time and labor cost are consumed, but also the production efficiency is low, which is difficult to meet the needs of large-scale industrial production. In addition, the cutting is flat, and further bevel cutting needs to be realized, which is low in production efficiency. SUMMARY

[0005] The purpose of the present invention is to solve the problems in the existing technology that the cutting method of paper straws is mostly direct hard cutting, which lacks a buffer mechanism. The paper straw fibers are prone to severe tearing at the moment of cutting, resulting in a large number of burrs at the cut, seriously affecting the product quality; secondly, it is impossible to meet the diversified cutting requirements of a flat end and an oblique cut at the other end; thirdly, when adjusting the length of the paper straws, manual adjustment is often required, resulting in low production efficiency.

[0011] Further, the fourth connecting rod is twice as long as the second connecting rod, the adjacent third connecting rods and the fourth connecting rods are staggered and rotationally connected, and the adjacent fourth connecting rods are staggered and rotationally connected; the first spring is arranged at the connection between the adjacent fourth connecting rods and the third connecting rods and the fourth connecting rods; the first spring is stretched to generate a displacement of 0.2-0.4mm, and the cutting time is extended by 0.1s.

[0012] Further, the second sliding block close to one end of the upper supporting block is fixedly connected to the upper surfaces of the first sliding rod, the second sliding rod and the fixed rod, and the second sliding block away from one end of the upper supporting block is slidably connected to the upper surfaces of the first sliding rod, the second sliding rod and the fixed rod; the second sliding rail is fixedly arranged on the first sliding rod, the second sliding rod and the fixed rod; the upper surface of one end of the supporting seat is fixedly installed with the production equipment, one side of the production equipment is provided with a drain pipe, the other end of the drain pipe is provided with a filter sedimentation tank, one side of the filter sedimentation tank is provided with a clean water tank, and the clean water tank is provided with a water inlet pipe.

[0014] The application also provides a straw paper production process, which comprises the following steps: Step one: the wastewater in the production equipment is discharged into the filter sedimentation tank through the drain pipe, and then the treated wastewater is pumped into the clean water tank through physical and chemical treatment, and then the water in the clean water tank is used for cleaning or other non-critical links in the production process through the water inlet pipe; Step two: the length is adjusted according to the length of the required paper straw; the bidirectional screw rod is driven to rotate by the motor, the first sliding block is driven to move left and right by the bidirectional screw rod, the first sliding rod is driven to move left and right on the first sliding rail by the first sliding block, and the plurality of uniformly arranged second sliding rods are driven to move left and right under the action of the first sliding rod, the first connecting rod and the second connecting rod, so as to adjust the length of the required paper straw; Step three: adjust the angle of the blade; one end of the button is pressed, the limiting block is away from the second limiting groove under the action of the second spring, then the rotating block is rotated, the blade is adjusted to 45 degrees, the button is released, and the limiting block is located in the second limiting groove for clamping; Step 4: Cut the paper straws into sections; the cylinder drives the connecting plate downward, and the connecting plate drives the second sliding block to slide downward on the second slide rail. The first spring is stretched, and the connection between the third connecting rod and the fourth connecting rod produces a slight displacement, so that the blade is pressed down to cut the paper straws into sections.

[0015] Furthermore, in the step three, the angles set between each two blades are different, wherein one blade is perpendicular to the paper straw, and the angle between the other blade and the paper straw is 45 degrees. When the blade is cutting, one end of the paper straw is flat and the other end is oblique. In the step four, the downward trajectory of the blade changes from a "rigid straight line" to an "elastic buffer curve", and the speed decreases in the initial stage of cutting.

[0016] Beneficial effects of the present invention: 1. The present invention provides a first spring at the adjacent fourth-link connection and the adjacent third- and fourth-link connection. When cutting the paper straw, the first spring is stretched, and the connection between the third and fourth links produces a slight displacement, thereby changing the downward trajectory of the blade from a "rigid straight line" to an "elastic buffer curve". The speed decreases in the initial stage of cutting, and the fibers gradually break instead of being torn instantly. The vibration amplitude caused by fiber tearing decreases, thereby reducing the burr rate of the cut, greatly reducing the burr rate of the cut of the paper straw.

[0017] 2. The present invention uses a motor to drive the bidirectional screw to rotate, the bidirectional screw drives the first sliding block to move left and right, the first sliding block drives the first slide bar to move left and right on the first slide rail, and the first slide bar drives multiple evenly arranged second slide bars to move left and right under the action of the first connecting rod and the second connecting rod, thereby adjusting the required length of the paper straws and improving the production efficiency of the paper straws.

[0018] 3. The present invention presses one end of the button, and under the action of the second spring, the limit block moves away from the second limit slot, and then rotates the rotating block. After the blade is adjusted to 45 degrees, the button is released to allow the limit block to be located in the second limit slot for engagement; the angles of each two blades are directly set at different levels, among which one blade is perpendicular to the angle of the paper straw, and the angle between the other blade and the paper straw is 45 degrees; when the blade is cutting, one end of the paper straw is flat and the other end is oblique cut, and the paper straw does not need to be further cut to complete the process of having one end of the paper straw be flat and the other end be oblique cut, which greatly improves production efficiency and saves costs.

A motor 6 is provided at one end of the bidirectional screw rod 601 for providing driving force to the bidirectional screw rod 601 .

[0030] The motor 6 drives the bidirectional screw rod 601 to rotate, the bidirectional screw rod 601 drives the first sliding block 602 to move left and right, the first sliding block 602 drives the first slide bar 10 to move left and right on the first slide rail 801, and the first slide bar 10 drives multiple evenly arranged second slide bars 12 to move left and right under the action of the first connecting rod 13 and the second connecting rod 1301; when moving left and right, the distances between the first slide bar 10, the second slide bar 12 and the fixed rod 11 are equal.

[0031] When the first sliding block 602 moves to the right, the first sliding bar 10 moves to the right. Under the action of the first connecting bar 13 and the second connecting bar 1301, the first sliding bar 10 drives multiple evenly distributed second sliding bars 12 to move to the right. The position of the fixed bar 11 remains unchanged. The distance between the first sliding bar 10 and the multiple evenly distributed second sliding bars 12 increases, and the corresponding length of the paper straws 29 will also become longer. Similarly, the distance between the first sliding bar 10 and the multiple evenly distributed second sliding bars 12 shortens, and the corresponding length of the paper straws 29 will also become shorter. The length of the paper straws 29 can be adjusted according to actual needs.

[0032] See also Figure 5-6 As shown, the first slide bar 10, the second slide bar 12 and the fixed bar 11 are all fixed with a second slide rail 1001, and the first slide bar 10, the second slide bar 12 and the fixed bar 11 are all provided with a plurality of evenly arranged second sliding blocks 15, and the lower surface of the second sliding block 15 is provided with a second slide groove 1002 matching the second slide rail 1001.

[0033] Multiple second sliding blocks 15 are distributed in a rectangular shape. In this embodiment, the second sliding blocks 15 are distributed in four rows and five columns. The second sliding block 15 near one end of the upper support block 8 is fixedly connected to the upper surfaces of the first sliding rod 10, the second sliding rod 12 and the fixed rod 11; the remaining second sliding blocks 15 are slidably connected to the upper surfaces of the first sliding rod 10, the second sliding rod 12 and the fixed rod 11.

A first spring 1602 is provided at the connection between adjacent fourth links 1601 and at the connection between adjacent third links 16 and fourth links 1601.

[0036] By pulling the second sliding block 15 at the bottom to slide up and down on the second slide rail 1001 , the second slide bar 12 and the second sliding block 15 on the fixed rod 11 are simultaneously driven to slide up and down under the action of the third slide bar 14 .

[0037] When the paper straw 29 is being cut, the first spring 1602 is stretched, and a slight displacement occurs at the connection between the third connecting rod 16 and the fourth connecting rod 1601, with a displacement value between 0.2-0.4 mm, thereby changing the downward trajectory of the blade 28 from a "rigid straight line" to an "elastic buffer curve". The speed decreases in the initial stage of cutting, and the cutting time is extended by 0.1s. The fibers gradually break instead of being torn instantly, and the vibration amplitude caused by fiber tearing is reduced from 0.3 mm to below 0.1 mm, and the burr rate of the cutting is reduced from 15% to 6%, greatly reducing the burr rate of the cutting of the paper straw 29.

[0038] See also Figure 7-8 As shown, one side of the second sliding block 15 near one end of the lower support block 9 is fixedly connected to the third sliding block 17, the upper surface of the third sliding block 17 is connected to the first rotating shaft 19, and the upper surface of the first rotating shaft 19 is slidingly provided with a connecting plate 18, and the middle part of the connecting plate 18 is provided with a penetrating first limiting groove 1801, and the first limiting groove 1801 is matched with the first rotating shaft 19.

[0039] A fixed block 20 is fixedly provided on the lower surface of the third sliding block 17, and a rotating block 24 is rotatably provided on the lower surface of the fixed block 20. The rotating block 24 is rotatably connected to the fixed block (20) through the first rotating shaft 19.

The other end of the first rotating shaft 19 passes through the fixed block 20 and is fixedly connected to the upper surface of the rotating block 24 and the blade 28. The angle between adjacent second limiting grooves 25 is 45 degrees, which is convenient for adjusting the cutting angle of the blade 28 and is used to cut oblique cuts in the paper straws 29.

[0041] The angles at which each two blades 28 are directly set are different, wherein one blade 28 is perpendicular to the paper straw 29, and the angle between the other blade 28 and the paper straw 29 is 45 degrees.

[0042] A hole 21 is provided on one side of the fixed block 20, and a second spring 22 is provided in the hole 21. The other end of the second spring 22 is connected to the inner wall of the button 26, and a limit block 27 is fixed to the other end of the button 26. The limit block 27 is cooperated with the second limit groove 25; a second rotating shaft 23 is provided on the fixed block 20, and the second rotating shaft 23 is located below the hole 21. The middle part of the button 26 is rotatably connected to the fixed block 20 through the second rotating shaft 23.

[0043] By pressing one end of the button 26, the limit block 27 moves away from the second limit slot 25 under the action of the second spring 22, and then the rotating block 24 is rotated to adjust the blade 28 to 45 degrees. The button 26 is released to make the limit block 27 located in the second limit slot 25 for engagement; the adjusted blade 28 can directly cut an oblique cut when cutting the paper straw 29, and there is no need to further cut the paper straw 29. The paper straw 29 is completed with a flat end and an oblique cut at the other end, which greatly improves production efficiency and saves costs.

[0044] The top of the connecting plate 18 close to one end of the first sliding rod 10 is fixedly connected to the output end of the cylinder 7 , and the cylinder 7 is fixed on the side wall of the supporting plate 5 .

[0045] The cylinder 7 drives the connecting plate 18 to move downward, and the connecting plate 18 drives the second sliding block 15 to slide downward on the second slide rail 1001. The first spring 1602 is stretched, and the hinge point between the third connecting rod 16 and the fourth connecting rod 1601 produces a slight displacement, so that the downward pressure trajectory of the blade 28 changes from a "rigid straight line" to an "elastic buffer curve". The speed decreases in the initial stage of cutting, and then the paper straw 29 is cut in segments.

[0046] A straw paper production process comprises the following steps: Step 1: The sewage in the production equipment 2 is discharged into the filtration sedimentation tank 3 through the discharge pipe 301, and then the treated wastewater is pumped into the clean water tank 4 through physical and chemical treatment. The water in the clean water tank 4 is then used for cleaning or other non-critical links in the production process through the water inlet pipe 401.

[0047] Step 2: Adjust the length of the paper straw 29 according to the required length. Drive the bidirectional screw 601 to rotate by the motor 6. The bidirectional screw 601 drives the first sliding block 602 to move left and right. The first sliding block 602 drives the first slide bar 10 to move left and right on the first slide rail 801. Under the action of the first connecting rod 13 and the second connecting rod 1301, the first slide bar 10 drives multiple evenly arranged second slide bars 12 to move left and right, thereby adjusting the required length of the paper straw 29.

[0048] Step three: Adjust the angle of the blade 28 by pressing one end of the button 26. Under the action of the second spring 22, the limit block 27 moves away from the second limit slot 25. Then rotate the rotating block 24 to adjust the blade 28 to 45 degrees. Release the button 26 so that the limit block 27 is located in the second limit slot 25 for engagement. The angles set between each two blades 28 are different. One blade 28 is perpendicular to the paper straw 29, and the angle between the other blade 28 and the paper straw 29 is 45 degrees. When the blade 28 is cutting, one end of the paper straw 29 is flat and the other end is oblique.

[0049] Step 4: Cut the paper straws 29 into sections. The cylinder 7 drives the connecting plate 18 to move downward. The connecting plate 18 drives the second sliding block 15 to slide downward on the second slide rail 1001. The first spring 1602 is stretched, and a slight displacement is produced at the connection between the third connecting rod 16 and the fourth connecting rod 1601, so that the downward trajectory of the blade 28 changes from a "rigid straight line" to an "elastic buffer curve". The speed decreases in the initial stage of cutting, and then the paper straws 29 are cut into sections.
