Description

Technical Field

[0001] The present invention mainly relates to the field of packaging, and specifically, it is a paper-plastic composite bag packaging cutting and collecting device. Background Art

[0002] With the increasingly strict environmental protection requirements, the use of plastic packaging bags is now strictly restricted. As a substitute for plastic packaging bags, paper-plastic packaging bags use paper materials to replace most of the plastics, which can achieve better environmental protection effects. Among them, thinner sheets such as single-piece packaged masks and antipyretic gels are now often packaged in paper-plastic composite bags.

[0003] The above products are heat-pressed and sealed by a paper-plastic composite bag packaging machine. After packaging, the two sides are cut by a cutting mechanism, and the products are cut off from each other, and finally collected. However, after cutting, there will still be residual paper-plastic edges adhered, and the packaged products will be pulled out of place by tearing and pulling actions. Therefore, when collecting the products, manual cleaning and sorting into boxes are still required, resulting in low efficiency. Summary of the Invention

Detailed implementation manners

[0028] In combination with the drawings and specific embodiments, the present invention will be further described. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by this application.

[0029] As Figure 1-8 shown, the paper-plastic composite bag packaging, cutting and collecting device of the present invention includes a pre-sequence packaging machine, and the pre-sequence packaging machine has a conveyor belt 8. The conveyor belt 8 completes the stable conveyance of the product during the feeding, encapsulation, and slitting processes of the pre-sequence packaging machine. The end of the conveyor belt 8 has a cutting mechanism, and the cutting mechanism completes the cutting of the edges of the paper-plastic composite bags of the products after hot-press encapsulation and the slitting between the products. The edges of the slit paper-plastic composite bags are in a continuous strip shape.

[0030] Above the downstream of the conveyor belt 8, a pressing frame 1 is provided. An elevating frame 11 is slidably mounted on the pressing frame 1. There is a pressing spring between the elevating frame 11 and the pressing frame 1, and the pressing spring is in a state of elastic force to push the elevating frame 11. A pressing roller 12 that is in tight contact with the top surface of the conveyor belt 8 is rotatably mounted on the elevating frame 11. There is a motor on one side of the elevating frame 11 to drive the pressing roller 12 to rotate. The pressing roller 12 squeezes the cut products so that they are stably pressed on the top surface of the conveyor belt 8, so that the products will not be pulled out of position when the outer cut edges are separated. Further, in this embodiment, the rotation direction of the pressing roller 12 is opposite to the rotation direction of the conveyor belt 8, and the linear velocity at the tangential position of the pressing roller 12 and the conveyor belt 8 is greater than the speed of the conveyor belt 8. Through the rotation drive of the pressing roller 12, the products can be pushed downstream, so as to separate the cut products from the upstream products. Specifically, a limit ring is installed at the bottom of the elevating frame 11 by means of threads, and the elastic force of the pressing spring is adjusted by adjusting the height of the limit ring, so as to adjust the pressure of the pressing roller 12 on the products.

[0031] Collection frames 13 are symmetrically installed on both sides of the conveyor belt 8. A pair of collection rollers 14 are rotatably mounted on the collection frames 13. The two collection rollers 14 are in contact with each other. The two collection rollers 14 are driven by the same motor, and the two collection rollers 14 are driven to rotate in opposite directions by gear transmission. Among them, the edges of the cut strip-shaped paper-plastic composite bags pass between the two collection rollers 14, so as to collect the edges of the strip-shaped paper-plastic composite bags, so as to separate the edges of the cut strip-shaped paper-plastic composite bags from the products through a pulling action, avoiding adhesion between the two. Specifically, the collection rollers 14 are made of rubber, and there are limit frames on the outer sides of the two collection rollers 14 to prevent the edges of the strip-shaped paper-plastic composite bags from running off and disengaging.

[0032] A diversion trough 15 is installed on the top surface of the end of the conveyor belt 8, and the diversion trough 15 is attached to the top surface of the conveyor belt 8. The diameter of the diversion trough 15 gradually decreases until it is slightly larger than the packaging width of the product. The end of the diversion trough 15 is bent downward by more than 90 degrees, and there is a limit baffle at the top of the bent part, so as to divert the packaged products. A receiving platform 16 is arranged below the diversion trough 15, and the products diverted by the diversion trough 15 fall onto the receiving platform 16. The width of the receiving platform 16 is the same as the width of the product, so as to position the products. Among them, the end of the diversion trough 15 and the receiving platform 16 form an acute angle, and the products will tilt actively to the other side of the receiving platform 16 after falling, so as to facilitate the subsequent picking roller 21 to grab the products.

[0033] Specifically, consistent with the commonly used paper-plastic composite bag packaging machine, this device is aimed at a double-position paper-plastic composite bag packaging machine, that is, a pair of paper-plastic composite bags are cut on the conveyor belt 8, so a partition plate 17 is set in the middle of the guide groove 15, and the partition plate 17 divides the guide groove 15 into left and right sides, so as to guide the products cut into two sides separately. Correspondingly, the two sides of the receiving platform 16 have receiving positions for limiting the positions of the two products respectively. Through the setting of the guide groove 15 and the receiving platform 16, the products after cutting can be guided and limited, so as to facilitate the subsequent grabbing of the products.

[0034] There is a feeding frame 2 below the end of the conveyor belt 8, on which a feeding roller 21 is rotatably mounted, and a servo drive motor for driving the feeding roller 21 to rotate is mounted on the side of the feeding frame 2. There is at least one pair of negative pressure ports 22 on the outer wall of the feeding roller 21, and the pair of negative pressure ports 22 respectively perform negative pressure adsorption on the products on both sides to achieve positioning and grabbing of the products. In order to cope with the change in the conveying speed of the conveyor belt 8, two pairs of negative pressure ports 22 are evenly arranged on the feeding roller 21 in a circumferential manner. Not all two pairs of negative pressure ports 22 can adsorb and grab the products every time they pass through the receiving platform 16. The two pairs of negative pressure ports 22 are used to compensate for errors to avoid the situation where the product fails to be grabbed at a single time or the product falls untimely, so that the other negative pressure port can be used to complete the grabbing before the next batch of products falls, thereby compensating for the error in equipment operation.

[0035] The other side of the pick-up roller 21 is provided with a material sorting rack 3. Specifically, the negative pressure port 22 has negative pressure when the receiving platform 16 rotates toward the material sorting rack 3, so that the product can be stably grasped all the time. The negative pressure of the negative pressure port 22 is interrupted when passing through the material sorting rack 3, and the product is placed on the material sorting rack 3. Specifically, the material sorting rack 3 is slightly lower than the center line position of the pick-up roller 21, so that the product can be tilted toward the material sorting rack 3 at a certain angle.

[0036] The spiral roller 31 is rotatably mounted on the outside of the material sorting rack 3, and the axis of the spiral roller 31 is consistent with the conveying direction of the conveyor belt 8. The spiral roller 31 has at least one and a half turns of spiral blades 32. After the product is released by the material taking roller 21 onto the material sorting rack 3, it leans on the spiral blades 32. The spiral rollers 31 are symmetrically arranged on the outside of the material sorting rack 3, and the spiral blades 32 on the two material sorting racks 3 rotate in opposite directions. The spiral roller 31 rotates inwardly to drive the product to move downstream until the product is separated from the spiral blades 32 and enters the downstream collection and regularization device.

[0037] A limiting plate 33 is arranged downstream of the spiral roller 31. Specifically, a baffle 36 is arranged in the middle of the material sorting rack 3. The baffle 36 cooperates with the limiting plate 33 to separate the two sides of the material sorting rack 3 into two material sorting positions, and the two material sorting positions respectively sort and regulate the products.

[0038] A pair of pushing mechanisms 34 are arranged at the end of the material rack 3. A pushing plate 35 is installed on the pushing mechanism 34. The pushing plate 35 is located between two limiting plates 33, so as to block the material placement position by using the limiting plates 33. By driving the pushing plate 35 to step in the material placement position through the pushing mechanism 34, the products conveyed progressively can be received. A buffer rack 4 is arranged above the two limiting plates 33. Two groups of side-sliding slide rails 41 parallel to the axis of the spiral roller 31 are arranged on the buffer rack 4. A side-sliding seat 42 is slidably arranged on each group of side-sliding slide rails 41. A side-sliding cylinder 43 is arranged between the buffer rack 4 and the side-sliding seat 42. By the push of the side-sliding cylinder 43, the side-sliding seat 42 can run stably along the side-sliding slide rail 41. A buffer cylinder 44 in the vertical direction is arranged on the side-sliding seat 42. A buffer plate 45 is arranged on the cylinder rod of the buffer cylinder 44. By the extension of the buffer cylinder 44, the buffer plate 45 can descend to block the front side of the product. Then the side-sliding cylinder 43 extends to push the product towards the pushing plate 35 to clamp the product.

[0039] Specifically, the pushing mechanism 34 includes a fixed lead screw nut 341, a fixed sleeve 342 and a propulsion frame 343. The propulsion frame 343 is provided with a propulsion slide rail 344 slidably matched with the fixed sleeve 342. A propulsion lead screw 345 matched with the fixed lead screw nut 341 is rotatably arranged on the propulsion frame 343. A propulsion servo motor 346 for driving the propulsion lead screw 345 to rotate is installed at the end of the propulsion frame 343. The pushing plate 35 is fixedly connected to the front end of the propulsion frame 343. Through the drive of the pushing servo motor 346, the precise displacement of the pushing plate 35 can be realized by the cooperation of the pushing lead screw 345 and the fixed lead screw nut 341, so as to realize the stable reception of the product and realize the automatic material handling of the device for the products packaged in paper-plastic composite bags.

[0040] The outer limiting plate 33 has an opening, which serves as the inlet for the clamping device of the product. Clamping seats 5 are arranged on both outer sides of the limiting plate 33. A fixed arm 51 is installed on the clamping seat 5. A swing mechanism 52 is installed at the front end of the fixed arm 51. A telescopic swing arm 6 is installed on the swing mechanism 52. The swing mechanism 52 drives the swing arm 6 to rotate 90 degrees, so that the swing arm can switch between the horizontal state and the position with a 90-degree downward orientation. A telescopic power mechanism 61 is arranged on the swing arm 6. Specifically, the swing arm 6 includes a rear-end driving arm 62 and a front-end sliding arm 63. The rear-end driving arm 62 is rotatably connected to the fixed arm 51. The swing mechanism 52 is driven by a servo motor, so that the swing arm 6 can rotate at a fixed angle. The front-end sliding arm 63 is slidably matched with the rear-end driving arm 62. The telescopic power mechanism 61 is an electric push rod. The end of the electric push rod is fixedly connected to the rear-end driving arm 62. The front end of the lead screw of the electric push rod is ball-connected to the front-end sliding arm 63. The telescopic movement of the swing arm 6 can be realized through the push cylinder of the electric push rod. Two-jaw clamps 7 are arranged at the front end of the swing arm 6. The two-jaw clamps 7 correspond to the opening. When clamping the product, the swing arm 6 is in the horizontal state. The electric push rod drives the swing arm 6 to extend, so that the two-jaw clamps 7 extend into the opening to clamp the product. Then the swing arm 6 contracts. The swing mechanism 52 drives the swing arm 6 to bend downward by 90 degrees. Then the swing arm 6 continues to extend, and the product is placed into the pre-positioned packaging box below. Then the two-jaw clamps 7 release the product, and the packaging of the product is completed. The two-jaw clamps 7 are sheet-shaped clamps driven by a double-headed cylinder. When clamping a paper-plastic composite bag, only the clamping pieces of the two-jaw clamps 7 pass through the opening.

[0041] Specifically, the buffer plate 45 is in a "C" shape, and the open side of the "C"-shaped buffer plate 45 faces the opening side. A notch is arranged in the middle of the push plate 35, and the notch faces the opening side. The open side of the buffer plate 45 and the notch of the push plate 35 both correspond to the clamping pieces of the two-jaw clamps 7. Thus, after the buffer plate 45 and the push plate 35 cooperate to initially clamp the product, the two-jaw clamps 7 can still further clamp the product through the notch and the open side.

[0042] When the device collects the cut paper-plastic composite packaging bag products, the specific process is as follows:

[0043] The pressing roller 12 presses the surface of the conveyor belt 8 under the elastic force of the pressing spring. After being cut, the paper-plastic composite packaging bag passes between the pressing roller 12 and the conveyor belt 8, and the edge parts on both sides of the paper-plastic composite packaging bag are pulled by the collecting roller 14 to be separated from the paper-plastic composite packaging bag. Subsequently, the paper-plastic composite packaging bag is transported to the receiving table 16 under the limiting and guiding action of the diversion groove 15. Then, under the rotation of the material-taking roller 21, a negative pressure is generated at the negative pressure port 22 to suck the paper-plastic composite packaging bag on the receiving table 16, and it is transported to the sorting rack 3 and then the negative pressure release is terminated. Subsequently, under the rotation of the spiral roller 31, the spiral blade 32 drives the paper-plastic composite packaging bag to displace downstream. Along with the stepping of the pushing plate 35, the paper-plastic composite packaging bag is received. When it is detected that the number of paper-plastic composite packaging bags reaches the standard, the buffer cylinder 44 extends to extend the buffer plate 45 to the front end of the paper-plastic composite packaging bag, and the side-sliding cylinder 41 extends to drive the buffer plate 45 to displace towards the pushing plate 35 to initially squeeze the paper-plastic composite packaging bag. Then the swing arm 6 extends, and the two-claw clamp 7 is extended into the opening to perform a secondary extrusion and clamping on the paper-plastic composite packaging bag. Then the swing arm 6 contracts to take out the paper-plastic composite packaging bag, and the buffer plate 45 and the pushing plate 35 are reset. Immediately afterwards, the swing arm 6 swings downward by 90 degrees to be perpendicular to the fixed arm 51, and the swing arm 6 continues to extend to load the clamped paper-plastic composite packaging bag into the positioned paper packaging box for sealing.
