Description

Technical Field

[0001] The invention belongs to the technical field of packaging bags, and in particular relates to a degradable and environmentally friendly packaging bag and a manufacturing device thereof. Background Art

[0002] Degradable environmentally friendly packaging bags are environmentally friendly bags that have better environmental protection effects than traditional plastic bags. This type of bag uses a special material that has a degrading agent added to it, which can naturally degrade within a certain period of time, thereby greatly reducing pollution to the environment. The degrading agent is a modified substance that can decompose plastic molecules so that they gradually decompose into carbon dioxide, water and other harmless substances in the natural environment. In this way, the long-term accumulation of plastic bags in nature and the adverse effects on the ecological environment are avoided. At present, the usage rate of degradable and environmentally friendly packaging bags is getting higher and higher. In order to facilitate the observation of the information of the items inside the packaging bag from the outside of the packaging bag, holes will be punched on the paper before folding the paper into a packaging bag, so as to facilitate the subsequent pasting of a transparent plastic film on the punched position. At present, the paper is usually wrapped around a winding roller to drive the winding roller to rotate to achieve the movement of the paper. When the winding roller rotates a certain distance, the paper moves a certain distance to facilitate fixed-point punching. Then, due to the lack of flattening equipment, wrinkles may be generated in the process of movement of the paper, which will cause the offset of the punching position, change of the punching shape, etc., causing trouble for the subsequent production process.

[0003] To this end, we provide a degradable and environmentally friendly packaging bag and a manufacturing device thereof to solve the above-mentioned problems. Summary of the invention

[0042] The working principle of this embodiment is as follows: Figure 5 As shown, the track in the equilateral triangle track 4 that is parallel to the surface of the production table 1 is set as track one, and the tracks connected to the two ends of track one are set as track two and track three. In the initial state, the paving component 5 is located at the highest point, that is, the sliding shaft 6 is located at the connecting end of track two and track three, the reset spring 13 is in a relaxed state, the pressing paving plate 10 is located at the lowest position of the inclined groove 9, and the protruding part of the cam 15 is vertically upward, that is, the cutting component 14 is located at the highest position.

[0043] First, the cam 15 is rotated so that the protruding portion of the cam 15 slowly rotates to face vertically downward, thereby driving the cutting assembly 14 to slide downward and finally cut and punch holes.

[0044] At the same time, the paving assembly 5 is slid to the track 2, and then the sliding shaft 6 slides downward along the track 2, thereby driving the H-shaped plate 7, the pressing paving plate 10 and the L-shaped slide plate 11 to slide downward, and at the same time the limiting plate 8 slides along the cutting assembly 14, that is, the cutting assembly 14 moves synchronously with the paving assembly 5, first the pressing paving plate 10 contacts the paper sheet 2, and then the paving assembly 5 continues to slide downward, thereby driving the pressing paving plate 10 to slide obliquely upward along the inclined groove 9, and then driving the T-shaped limiting rail 49 of the pressing paving plate 10 to slide upward along the T-shaped limiting groove 50 on the L-shaped slide plate 11, and at the same time making the L The H-shaped slide plate 11 squeezes the return spring 13. When the slide shaft 6 slides to the connection end between the track two and the track one, the H-shaped plate 7 just contacts the paper piece 2, and then drives the slide shaft 6 to slide into the track one. Since the track one is parallel to the surface of the production table 1, it drives the flattening component 5 to slide along the surface of the production table 1, and then drives the flattening component 5 to slide toward the direction close to the track three. During this process, the two groups of flattening components 5 move away from each other, and the paper piece 2 on the surface of the production table 1 is flattened. When the slide shaft 6 rotates to the connection end between the track one and the track three, the flattening work is completed, and then the paper piece 2 can be cut and punched by the cutting component 14.

[0045] After the cutting and punching is completed, continue to rotate the cam 15 so that the protruding part of the cam 15 rotates vertically upward. At the same time, slide the flattening component 5 from the connecting end of track one and track three to track three, and slide along track three to the connecting end of track three and track two, that is, return to the initial state, and then move the next position of the paper sheet 2 where a hole needs to be punched to just below the cutting component 14 for the next cutting and punching.

[0046] In this embodiment, by sliding the flattening component 5 along the track two, the track one and the track three in sequence, the flattening component 5 is driven to approach the paper sheet 2 on the surface of the production table 1 in the track two, and the two flattening components 5 are driven to move away from each other along the surface of the paper sheet 2 in the track one, so that the two flattening components 5 move from the middle of the paper sheet 2 to both sides to flatten it, and the flattening component 5 slides upward to the initial state of the track in the track three, and the cycle is repeated to achieve periodic automatic flattening of the paper sheet 2.

[0047] At the same time, when the flattening component 5 moves downward, the pressing flat plate 10 first contacts the paper sheet 2 and then the flattening component 5 continues to slide downward, so that the pressing flat plate 10 slides obliquely upward along the inclined groove 9, so that the pressing flat plate 10 slides from the middle of the paper sheet 2 to both sides to flatten it, and finally becomes parallel to the bottom surface of the H-shaped plate 7, thereby improving the flattening efficiency.

[0048] For specific embodiment 2, please refer to Figure 1-18On the basis of the specific embodiment 1, two guide gear rings 16 are rotatably arranged on the side of the mounting plate 3; the two guide gear rings 16 are meshed together; the circumcenter of the equilateral triangle track 4 coincides with the center of the circle of the guide gear ring 16; a guide rail 17 is fixed to the inner wall of the guide gear ring 16; and the sliding shaft 6 is slidably matched with the inner wall of the guide rail 17.

[0049] Specifically, a first toothless ring 18 is rotatably provided on the side of the mounting plate 3; the first toothless ring 18 is fixedly connected to a guide rail 17; a second toothless ring 19 is fixed to the side of the first toothless ring 18; the serrations on the first toothless ring 18 and the second toothless ring 19 are staggered, and the first toothless ring 18 and the second toothless ring 19 are projected on the side of the mounting plate 3 to form a complete toothed ring segment, and the serrations on the first toothless ring 18 and the second toothless ring 19 have only one end and are continuous.

[0050] Furthermore, the cutting assembly 14 includes a driving box 20 slidably arranged on the side of the mounting plate 3; an electric telescopic rod 21 is fixed to the bottom surface of the driving box 20; a cutting knife 22 is fixed to the telescopic end of the electric telescopic rod 21; two linkage plates 23 are symmetrically fixed to the surface of the driving box 20; a limiting groove 24 is provided through the side of the linkage plate 23; and the limiting plate 8 is slidably matched with the limiting groove 24.

[0051] Furthermore, a first toothed ring 25 which meshes with the first toothless ring 18 is rotatably provided on the side of the mounting plate 3; an L-shaped fixing plate 26 is fixed on the side of the mounting plate 3; a second toothed ring 27 which meshes with the second toothless ring 19 is rotatably provided on the side of the L-shaped fixing plate 26; the first toothed ring 25 is coaxial with the second toothed ring 27; a rotating shaft 28 is fixed on the side of the first toothed ring 25; the rotating shaft 28 is rotatably engaged with the two mounting plates 3; the cam 15 is fixed on the side surface of the rotating shaft 28; a T-shaped slide rail 30 is fixed on the surface of the drive box 20; a T-shaped slide groove 29 which slidably engages with the inner wall of the T-shaped slide rail 30 is provided on the side surface of the cam 15.

[0052] The working principle of this embodiment is: first rotate the first toothless ring 18, the first toothless ring 18 drives the first toothed ring 25 to rotate, and then drives the rotating shaft 28 to rotate, and then drives the cam 15 to rotate, so that the protruding part of the cam 15 rotates from vertically upward to vertically downward. During this process, the T-shaped slide rail 30 slides along the inner wall of the T-shaped slide groove 29, and then drives the T-shaped slide rail 30 to slide downward, and then drives the drive box 20, the electric telescopic rod 21, the cutting knife 22 and the linkage plate 23 to move downward.

[0053] At the same time, the first toothless ring 18 drives a guide gear ring 16 to rotate, and then drives another guide gear ring 16 to rotate. The rotation directions of the two guide gear rings 16 are opposite. The rotation of the guide gear rings 16 drives the corresponding guide rails 17 to rotate, and then drives the sliding shaft 6 to slide along the inner wall of the guide rail 17, and at the same time drives the sliding shaft 6 to slide along the inner wall of the equilateral triangle track 4.

[0054] The sliding shaft 6 slides downward along the track 2, thereby driving the H-shaped plate 7, the pressing paving plate 10 and the L-shaped slide plate 11 to slide downward, and at the same time the limiting plate 8 slides along the inner wall of the limiting groove 24, that is, the cutting component 14 and the paving component 5 move synchronously, first the pressing paving plate 10 contacts the surface of the production table 1, and then the paving component 5 continues to slide downward, thereby driving the pressing paving plate 10 to slide obliquely upward along the inclined groove 9, and then driving the T-shaped limiting rail 49 on the pressing paving plate 10 to slide upward along the T-shaped limiting groove 50 on the L-shaped slide plate 11, and at the same time When the sliding shaft 6 slides to the connection end between track 2 and track 1, the H-shaped plate 7 just contacts the paper piece 2, and then drives the sliding shaft 6 to slide into track 1. Since track 1 is parallel to the surface of the production table 1, it drives the flattening component 5 to slide along the surface of the production table 1, and then drives the flattening component 5 to slide toward the direction close to track three. In this process, the two groups of flattening components 5 move away from each other, and the paper pieces 2 on the surfaces of the two production tables 1 are flattened. When the sliding shaft 6 rotates to the connection end between track 1 and track three, the flattening work is completed.

[0055] Then, the telescopic end of the electric telescopic rod 21 is driven to extend, thereby driving the cutting knife 22 to move downward to cut and punch the paper sheet 2.

[0056] After the cutting and punching is completed, the first toothless ring 18 continues to rotate to drive the first toothed ring 25 to rotate, and then drives the rotating shaft 28 and the cam 15 to rotate, so that the protruding part of the cam 15 rotates to be vertically upward. At the same time, the flattening component 5 is slid from the connecting end of track one and track three to track three, and slides along track three to the connecting end of track three and track two, that is, it returns to the initial state, and then the next position of the paper sheet 2 that needs to be punched is moved to just below the cutting component 14 for the next cutting and punching.

[0057] In this embodiment, the two guide gear rings 16 are driven to rotate by rotating the first toothless ring 18, and the rotation of the guide gear ring 16 drives the guide rail 17 to rotate, and then the guide rail 17 drives the sliding shaft 6 to slide along the inner wall of the guide rail 17, and then drives the sliding shaft 6 to slide along the equilateral triangle track 4, and then drives the paving component 5 to move. At the same time, the first toothless ring 18 drives the first gear ring 25 to rotate, and then drives the rotating shaft 28 and the cam 15 to rotate, and then drives the T-shaped slide rail 30 to slide along the inner wall of the T-shaped slide groove 29, and then drives the cutting component 14 to move up and down. The synchronous operation of the paving component 5 and the cutting component 14 is achieved by rotating the first toothless ring 18.

[0059] Specifically, two adjacent side surfaces of the mounting plate 3 are rotatably provided with two bevel gears 32 respectively; the two bevel gears 32 are meshed together; a first pulley 33 is fixed to the side surface of the second gear ring 27 and the side surface of a bevel gear 32; a first belt 34 is transmitted between the two first pulleys 33; a second pulley 35 is fixed to one end of the two winding rollers 31; a second belt 36 is transmitted between the two second pulleys 35; a third pulley 37 is fixed to the side surface of a second pulley 35 and the side surface of another bevel gear 32; a third belt 38 is transmitted between the two third pulleys 37.

[0060] The working principle of this embodiment is as follows: in the initial state, the saw teeth of the first toothless ring 18 mesh with the first toothed ring 25, while the saw teeth of the second toothless ring 19 separate from the second toothed ring 27. First, the first toothless ring 18 is rotated to drive the first toothed ring 25 to rotate one circle, thereby driving the flattening component 5 and the cutting component 14 to move synchronously to cut and punch the paper sheet 2 and return to the initial state.

[0061] Then the saw teeth of the first toothless ring 18 are disengaged from the first toothed ring 25, while the saw teeth of the second toothless ring 19 are meshed with the second toothed ring 27. The first toothless ring 18 continues to rotate to drive the second toothless ring 19 to rotate, and the second toothless ring 19 drives the corresponding second toothed ring 27 to rotate, thereby driving the corresponding first pulley 33 to rotate, and driving the other first pulley 33 to rotate through the first belt 34, thereby driving the corresponding bevel gear 32 to rotate, and then driving the other bevel gear 32 to rotate, thereby driving the corresponding third pulley 37 to rotate, and then driving the other third pulley 37 to rotate through the third belt 38, thereby driving the corresponding second pulley 35 to rotate, and then through The second belt 36 drives another second pulley 35 to rotate, and then the two winding rollers 31 are driven to rotate by the corresponding second pulleys 35, and then the paper sheet 2 is driven to move, so that the next position to be punched on the paper sheet 2 is moved to just below the cutting assembly 14, and then the saw teeth on the second toothed ring 19 are disengaged from the second toothed ring 27, and at the same time, the saw teeth of the first toothed ring 18 are engaged with the first toothed ring 25, and then the first toothed ring 18 continues to rotate to drive the first toothed ring 25 to rotate one circle, and then the flattening assembly 5 and the cutting assembly 14 are driven to move synchronously to cut and punch the paper sheet 2 and return to the initial state, and the cycle is repeated. After the paper sheet 2 is cut, it can be torn off through the tear line 54 for use.

[0062] In this embodiment, the second toothless ring 19 is driven to rotate by rotating the first toothless ring 18, and the first toothless ring 18 drives the first toothed ring 25 to rotate one circle, thereby driving the flattening component 5 and the cutting component 14 to move synchronously to cut and punch the paper piece 2 and return to the initial state, the second toothless ring 19 drives the second toothed ring 27 to rotate, and drives the winding roller 31 to rotate and move the position of the paper piece 2 through the first pulley 33, the first belt 34, the second pulley 35, the second belt 36, the third pulley 37 and the third belt 38. By rotating the first toothless ring 18, the flattening component 5, the cutting component 14, and the winding roller 31 can move the paper piece 2 in uninterrupted sequential operation, thereby saving driving force.

[0063] For specific example 4, please refer to Figure 1-18 On the basis of the specific embodiment one, the specific embodiment two and the specific embodiment three, two partitions 39 are fixed between the two opposite inner walls of the production table 1 and between the two winding rollers 31; a recovery chamber 40 is formed between the two partitions 39 and the inner wall of the production table 1; a recovery groove 41 connected to the inside of the recovery chamber 40 is opened on the surface of the production table 1; a rotating drum 42 is rotatably arranged on the inner wall of the recovery chamber 40; a second servo motor is fixed to the side of the production table 1; the output end of the second servo motor is fixedly connected to the rotating drum 42; a number of suction holes 43 connected to the inside of the rotating drum 42 are evenly opened on the side surface; a suction pipe 44 is fixed through one end of the rotating drum 42; a number of mounting grooves 45 are evenly opened on the side surface of the suction pipe 44; an elastic diaphragm 46 is installed on the inner wall of the mounting groove 45.

[0064] Specifically, an air pump 47 is fixed to the side of the production table 1; an air suction pipe 48 is fixed to the air suction end of the air pump 47; and the air suction pipe 48 is sleeved on the side of the suction pipe 44.

[0065] The working principle of this embodiment is as follows: after the cutting assembly 14 completes the cutting and punching of the paper sheet 2, the cut waste paper falls onto the rotating drum 42 along the recovery groove 41. At this time, the air pump 47 is turned on to make the air pump 47 suck air along the suction hole 43, the inside of the rotating drum 42, the suction pipe 44 and the suction pipe 48, thereby adsorbing and fixing the waste paper. When the air passes through the elastic diaphragm 46, the elastic diaphragm 46 will be blown up, so that the elastic diaphragm 46 and the inner wall of the suction pipe 48 are closely fitted, thereby increasing the air tightness. Then the rotating drum 42 is rotated 180 degrees, so that the suction hole 43 is rotated from vertically upward to vertically downward. Then the air pump 47 is turned off to release the adsorption and fixation of the waste paper. The paper sheet 2 falls into the inside of the recovery chamber 40, i.e., the recovery of the waste paper is completed. Then the rotating drum 42 is reversed to make the suction hole 43 rotate from vertically downward to vertically upward, waiting for the adsorption and conveying of the next piece of waste paper.
