Description

Technical Field

[0001] The invention belongs to the field of packaging machinery, and particularly relates to a paper bag sealing strip pasting device and a pasting method thereof. Background Art

[0002] Currently, paper bags used in bakeries have a sealing strip with a thin wire pasted on the opening. When sealing the paper bag, the sealing strip and a part of the paper bag opening are folded inward, and then the thin wires at both ends of the sealing strip are folded relative to each other to complete the paper bag sealing. This paper bag is convenient to pack and unpack. Although my country has relatively complete and mature production line equipment for paper bags and sealing strips, most of the pasting machines on the market are for peeling labels on rolls, and there is no device that can peel off the release paper from the sealing strips one by one and paste them on the paper bag. This process is still done manually, that is, the worker needs to manually tear off the release paper from the sealing strip, and then paste the side of the sealing strip with glue to the opening of the paper bag. The workload is large and the labor cost is high. In response to this situation, it is necessary to develop a device that can replace the manual pasting of the sealing strip on the opening of the paper bag. Summary of the Invention

[0016] The present invention provides a method for pasting a paper bag sealing strip pasting device, which is specifically as follows:

[0017] Step 1: Place a stack of sealing strips on the conveyor belt of the sealing strip delivery mechanism at the input end of the belt conveyor mechanism, and use a heavy object to press on the top of the stack of sealing strips, with the release paper of each sealing strip located at the bottom; place a stack of paper bags with the same number as the sealing strips on the conveyor belt of the paper bag delivery mechanism at the input end of the belt conveyor mechanism, and use another heavy object to press on the top of the stack of paper bags, with the opening of each paper bag away from the input end of the corresponding belt conveyor mechanism.

[0018] Step 2: The controller controls each drive motor 1 to drive each conveyor roller to start working, and each drive member drives the corresponding conveyor shaft to rotate; each conveyor belt drives a sealing strip at the bottom layer and a paper bag at the bottom layer to be conveyed to the output end of the corresponding belt conveyor mechanism, respectively. The sealing strip and the paper bag respectively pass through the gap between the corresponding conveyor belt and the conveyor roller located in the middle of the corresponding belt conveyor mechanism, and are squeezed between the corresponding conveyor belt and the conveyor roller located at the output end of the corresponding belt conveyor mechanism, and are respectively conveyed to the corresponding support plate. The remaining sealing strip and paper bag fall onto the corresponding conveyor belt under the action of the gravity of the corresponding weight; then, each drive member stops working, and the controller controls each drive motor 1 to stop working, completing the conveying of the sealing strip and paper bag. During the conveying process, the conveyor roller located in the middle of each belt conveyor mechanism blocks the remaining sealing strip and paper bag, preventing the remaining sealing strip and paper bag from passing through the corresponding gap.

[0019] Step 3: The controller controls the dual-axis telescopic cylinder through the electromagnetic reversing valve to drive the vacuum adsorption platform to bring each suction cup into contact with the sealing strip, and the arc plate presses on the backing paper of the sealing strip. The controller controls each suction cup through the electromagnetic reversing valve to attract the sealing strip. The controller controls the driving motor 2 to drive the rotating shaft to drive the cam to rotate one circle, wherein the far rest section of the cam first contacts the connecting rod 1, and the connecting rod 1, the connecting rod 2, the connecting shaft 1 and the sliding rods do not rotate. The rotating shaft drives the sliding rods 1 and the stripping knife to move in the direction of each sliding rod close to the support plate in the sealing strip feeding mechanism through the connecting rod 3 and the connecting rod. As the stripping knife moves in the direction of the stripping knife, the blade part of the stripping knife head enters between the release paper and the base paper of the sealing strip, and the stripping knife head separates a part of the release paper and the base paper of the sealing strip; then the return section of the cam contacts the connecting rod 1, and the connecting rod 1 drives the sliding rods, the sliding rods 1 and the stripping knife to move downward through the connecting rod 2 and the connecting shaft 1, and the rotating shaft drives the sliding rods 1 and the stripping knife to move in the direction of each sliding rod away from the support plate in the sealing strip feeding mechanism through the connecting rod 3 and the connecting rod. The stripping knife head carries a part of the release paper peeled off from the sealing strip and contacts the limit block, and the limit block prevents the stripping knife from The head continues to move downward, thereby stretching the tool spring, and the limit block and the stripping knife head clamp a part of the peeled release paper. At the same time, the controller controls the double-axis telescopic cylinder to drive the vacuum adsorption platform to rise to the initial height through the electromagnetic reversing valve. The controller controls the rodless cylinder to drive the double-axis telescopic cylinder to drive the vacuum adsorption platform, each suction cup and the bottom paper of the sealing strip to translate toward the direction of the paper bag delivery mechanism through the electromagnetic reversing valve. The release paper and the bottom paper of the sealing strip are separated; then the near-rest section and the push section of the cam contact the connecting rod 1 in sequence, and the connecting rod 1 drives each slide bar, each slide bar 1 and the stripping knife to move upward through the connecting rod 2 and the connecting shaft 1. The rotating shaft drives each slide bar 1 and the stripping knife to continue to move along each slide bar away from the support plate in the sealing strip delivery mechanism through the connecting rod 3 and the connecting rod. The stripping knife head is disengaged from the limit block, and the restoring force of the tool spring drives the stripping knife head to return to its original state, and the torn release paper falls on the frame.

[0020] Step 4: After the controller controls the rodless cylinder to drive the double-axis telescopic cylinder through the electromagnetic reversing valve to drive the vacuum adsorption platform to move above the support plate of the paper bag delivery mechanism, the controller controls the double-axis telescopic cylinder to drive the vacuum adsorption platform through the electromagnetic reversing valve to drive the bottom paper of the sealing strip to descend to a preset height of two. The bottom paper of the sealing strip is pasted to the opening of the paper bag. At this time, the pasting work of the sealing strip and the paper bag is completed; then the controller controls the double-axis telescopic cylinder to drive the vacuum adsorption platform to drive the bottom paper of the sealing strip and the paper bag to rise to a preset height of two through the electromagnetic reversing valve. The electromagnetic reversing valve controls the rodless cylinder to drive the double-axis telescopic cylinder to drive the vacuum adsorption platform and the pasted sealing strip and paper bag to move horizontally toward the sealing strip delivery mechanism to the top of the collection box; then the controller controls the suction cups to release the sealing strip through the electromagnetic reversing valve, and the pasted sealing strip and paper bag fall onto the collection box, completing the collection of the finished product after pasting; the controller controls the rodless cylinder to drive the double-axis telescopic cylinder through the electromagnetic reversing valve to drive the vacuum adsorption platform to continue to move horizontally toward the sealing strip delivery mechanism until the double-axis telescopic cylinder returns to its original position.

[0021] Step 5. Repeat steps 2 to 4 until all sealing strips and paper bags are attached.

[0022] The beneficial effects of the present invention are as follows:

[0023] The present invention adopts a roller friction feeding method, and realizes the single-line output of the sealing strip and the paper bag through the sealing strip feeding mechanism and the paper bag feeding mechanism; the present invention realizes the separation of the release paper and the bottom paper on the sealing strip through the cooperation of the release paper peeling mechanism and the sealing strip moving and pasting mechanism, and realizes the separation of the release paper and the bottom paper on the sealing strip. In the present invention, when the connecting rod 1 contacts the far rest section of the cam, the stripping knife moves horizontally along each sliding rod, and the blade of the stripping knife enters between the release paper and the bottom paper of the sealing strip, thereby partially separating the release paper and the bottom paper on the sealing strip; when the connecting rod 1 contacts the return section of the cam, the stripping knife rotates downward, and the stripping knife head of the stripping knife and the limit block clamp the peeled part of the release paper, and then the double-axis telescopic cylinder drives the vacuum adsorption platform to drive the bottom paper to rise, and the rodless cylinder drives the double-axis telescopic cylinder to drive the bottom paper to move horizontally, thereby realizing the complete separation of the release paper and the bottom paper on the sealing strip; the present invention realizes the pasting work of the sealing strip and the paper bag through the sealing strip moving and pasting mechanism, and realizes the collection work of the finished products after the pasting is completed.

[0024] 2. The present invention replaces manual labor to realize the peeling of the release paper on the sealing strip and the pasting of the sealing strip and the paper bag, which requires less labor and reduces labor costs. In addition, the present invention has a simple structure and is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] More preferably, both ends of the conveying roller 1-4 pass through two circular holes opened on the corresponding storage box 1-3 and are supported on the frame through the bearing seat 1-9.

[0042] As a preferred embodiment, the base of the rodless cylinder 2-1 is fixed on the frame, the slider 2 of the rodless cylinder 2-1 is fixed to the cylinder body of the double-axis telescopic cylinder 2-2 through the cylinder connecting plate 2-6, and the end of the piston rod of the double-axis telescopic cylinder 2-2 is fixed to the vacuum adsorption platform 2-3.

[0047] The present invention provides a method for pasting a paper bag sealing strip pasting device, which is specifically as follows:

[0048] Step 1: Place a stack of sealing strips on the conveyor belt 1-2 of the sealing strip delivery mechanism 1 at the input end of the belt conveyor mechanism, and use a heavy object to press on the top of the stack of sealing strips, with the release paper of each sealing strip located at the bottom; place a stack of paper bags with the same number as the sealing strips on the conveyor belt 1-2 of the paper bag delivery mechanism 5 at the input end of the belt conveyor mechanism, and use another heavy object to press on the top of the stack of paper bags, with the opening of each paper bag away from the input end of the corresponding belt conveyor mechanism.

[0049] Step 2: The controller controls each drive motor 1 to start driving each conveyor roller 1-4, and each drive member drives the corresponding conveyor shaft 1-1 to rotate. Each conveyor belt drives a sealing strip and a paper bag at the bottom layer to be transported to the output end of the corresponding belt conveyor mechanism. The sealing strip and the paper bag respectively pass through the gap between the corresponding conveyor belt and the conveyor roller 1-4 located in the middle of the corresponding belt conveyor mechanism, and are squeezed between the corresponding conveyor belt and the conveyor roller 1-4 located at the output end of the corresponding belt conveyor mechanism, and are respectively transported to the corresponding support plate 1-5. The remaining sealing strip and paper bag fall onto the corresponding conveyor belt under the action of gravity of the corresponding weight. Then, each drive member stops working, and the controller controls each drive motor 1 to stop working, completing the conveying of the sealing strip and paper bag. During the conveying process, the conveyor roller 1-4 located in the middle of each belt conveyor mechanism blocks the remaining sealing strip and paper bag, preventing the remaining sealing strip and paper bag from passing through the corresponding gap, thereby achieving single-line output of the sealing strip and paper bag.

[0050] Step 3: The controller controls the dual-axis telescopic cylinder 2-2 via the electromagnetic reversing valve to drive the vacuum adsorption platform 2-3, which drives each suction cup 2-4 to contact the sealing strip, and the arc plate 2-5 presses on the backing paper of the sealing strip. The controller controls the electromagnetic reversing valve to control each suction cup 2-4 to attract the sealing strip. The controller controls the drive motor 2 to drive the rotating shaft to drive the cam 3-2 to rotate one circle, wherein the far rest section of the cam 3-2 first contacts the connecting rod 1 3-3, as shown in FIG. Figure 7As shown, the connecting rod 1 3-3, the connecting rod 2 3-4, the connecting shaft 1 3-8 and each slide bar 3-5 do not rotate, and the rotating shaft drives each slide bar 1 3-6 and the stripping knife 3-7 to translate along each slide bar 3-5 toward the direction close to the support plate 1-5 in the sealing strip delivery mechanism 1 through the connecting rod 3 3-9 and the connecting rod 3-10. As the stripping knife 3-7 translates, the blade of the stripping knife head 3-7-3 enters between the release paper and the bottom paper of the sealing strip, and the stripping knife head 3-7-3 separates a part of the release paper and the bottom paper of the sealing strip; then the return section of the cam 3-2 connects with the connecting rod 1 3-3 When the sealing strip is delivered to the sealing strip, the stripping knife 3-7 is moved downwards by the connecting rod 1 3-3 through the connecting rod 2 3-4 and the connecting shaft 1 3-8.

The stripping knife head 3-7-3 carries a part of the release paper peeled off from the sealing strip and contacts the limit block 3-11. The limit block 3-11 prevents the stripping knife head 3-7-3 from moving further downwards, thereby causing the knife to rebound. The spring 3-7-4 is stretched, and the limit block 3-11 and the peeling knife head 3-7-3 clamp the peeled part of the release paper. At the same time, the controller controls the double-axis telescopic cylinder 2-2 through the electromagnetic reversing valve to drive the vacuum adsorption platform 2-3 to the initial height. The controller controls the rodless cylinder 2-1 through the electromagnetic reversing valve to drive the double-axis telescopic cylinder 2-2 to drive the vacuum adsorption platform 2-3, each suction cup 2-4 and the bottom paper of the sealing strip to move horizontally toward the paper bag delivery mechanism 5. The release paper and the bottom paper of the sealing strip are separated. Then the near-rest section and the push section of the cam 3-2 are connected with the connecting rod 3- 3, the connecting rod 1 3-3 drives each slide bar 3-5, each slider 1 3-6 and the stripping knife 3-7 to move upward through the connecting rod 2 3-4 and the connecting shaft 1 3-8, and the rotating shaft drives each slider 1 3-6 and the stripping knife 3-7 along each slide bar 3-5 to continue to move away from the supporting plate 1-5 in the sealing strip feeding mechanism 1 through the connecting rod 3 3-9 and the connecting rod 3-10.
