[0019] (III) Beneficial effects
[0020] Compared with the prior art, the present invention provides a packaging bag sealing and cutting device, which has the following beneficial effects:
[0021] 1. The packaging bag packaging and cutting device has a special design for the slideway in the inclined feeding slide. When the vacuum rice bag falls into the inclined feeding slide, it will first slide down along the wide slide, and the end of the vacuum rice bag away from the protruding edge seal will contact the bending part where the wide slide and the narrow slide are connected. At this time, the vacuum rice bag will slide down along the bending part where the wide slide and the narrow slide are connected into the narrow slide, and because the width of the narrow slide is adapted to the length of the bulging part of the vacuum rice bag, the vacuum rice bags that slide down into the narrow slide will be neatly arranged , that is, the two ends are aligned, and when it continues to slide down to the material placement and cutting plate, the error of cutting the protruding sealed edge of each vacuum rice bag can be reduced. At the same time, since a concave platform is provided on the side of the unloading slide corresponding to the narrow slide, the vertical distance between the top of the concave platform and the inner wall of the bottom of the narrow slide is less than half the thickness of the vacuum rice bag, the protruding sealed edge of the vacuum rice bag can be located above the top of the concave platform and arranged neatly in a horizontal shape, which is conducive to the subsequent cutting of the convex sealed edge of the vacuum rice bag, thereby improving the overall functionality and convenience of the device.
[0022] 2. The packaging bag packaging and cutting device can intermittently discharge the vacuum rice bags transported on the assembly line conveyor belt to the loading and cutting board through the intermittent discharge blocking mechanism on the discharge slide. At this time, since the end of the vacuum rice bag away from the protruding edge seal will always fit the narrow sliding side inner wall and the limiting partition, it is ensured that there will be no position deviation of the vacuum rice bag on the loading and cutting board each time the material is discharged, and the specifications of the protruding edge seal of the vacuum rice bag are cut to be consistent each time, thereby improving the cutting quality of the device for the easy-tear edge seal.
[0023] 3. The packaging bag sealing and cutting device, the vacuum rice bags gathered in the narrow slide will continue to move down for a distance and then continue to be blocked by the upper partition plate of the upper blocking rod, thereby stopping the unloading. In the process of continuous rotation of the special-shaped turntable, intermittent unloading can be completed, that is, a bag of vacuum rice bags can be unloaded onto the material placement and cutting board through the unloading slide plate each time, and the cutting operation of the easy-to-tear edge can be completed through the edge sealing and cutting device, thereby adapting to the automation and practical rationality of the actual production process of vacuum rice bags, while improving the functionality of the device.
[0024] 4. The packaging bag packaging and cutting device can intermittently discharge the vacuum rice bags transported on the assembly line conveyor belt to the material placement and cutting board through the intermittent discharge blocking mechanism on the discharge slide. At this time, since the end of the vacuum rice bag away from the protruding edge seal will always fit the narrow sliding side inner wall and the limiting partition, it is ensured that there will be no position deviation of the vacuum rice bag on the material placement and cutting board each time the material is discharged, and the specifications of the protruding edge seal of the vacuum rice bag are cut to be consistent each time, thereby improving the cutting quality of the device for the easy-tear edge seal.
[0025] 5. The packaging bag sealing and cutting device has two sets of partition sheets on the upper blocking rod and the lower group of rods, whose end sides close to each other are in the shape of an arc surface, and the thickness of the arc surface end side of the partition sheet is less than the thickness of the upper blocking rod and the lower group of rods, and the shortest distance between the two sets of partition sheets is the width of the vacuum rice bag. When the partition sheets on the lower group of rods are synchronously moved upward and inserted into the gap between the two vacuum rice bags, thereby blocking all the vacuum rice bags behind, the partition sheets can be prevented from damaging the packaging bags, thereby improving the operational practicability of the device and ensuring the quality of product production.

[0044] The edge banding cutting device 7 includes a horizontal base plate 15, a side base plate 17, a turntable 19, a cutting swivel 20, a cutting knife 21 and a servo motor 22.

When feeding through the assembly line conveyor belt 1, the staff only needs to point the protruding sealed edge of the vacuum rice bag toward the side of the blanking slide 2 where the concave platform 5 is opened. When the vacuum rice bag falls into the inclined blanking slide 2, it will first slide down along the wide slide 3, and the end of the vacuum rice bag away from the protruding sealed edge will contact the bending place where the wide slide 3 and the narrow slide 4 are connected. At this time, the vacuum rice bag will slide down along the bending place where the wide slide 3 and the narrow slide 4 are connected and enter the narrow slide 4, and because The width of the narrow slide 4 is adapted to the length of the bulging portion of the vacuum rice bag. The vacuum rice bags that slide into the narrow slide 4 will be neatly arranged, that is, the two ends will be aligned. When they continue to slide into the material placement and cutting plate 6, the error in cutting the protruding sealed edge of each bag of vacuum rice bags can be reduced.

The semicircular ring 28 is semicircular, and the upper end of the semicircular ring 28 is fixedly provided with an integrated upper connecting rod 29, and the lower end of the semicircular ring 28 is fixedly provided with an integrated lower connecting rod 30. The upper connecting rod 29 and the lower connecting rod 30 are inclined parallel to the material unloading slide 2. The length of the upper connecting rod 29 is greater than that of the lower connecting rod 30, and the semicircular ring 28, the upper connecting rod 29 and the lower connecting rod 30 form a U-shape with different lengths on both sides. The end side of the upper connecting rod 29 is fixedly provided with an upper blocking rod 33 that extends to the top of the material unloading slide 2 as an integral whole, and the end side of the lower connecting rod 30 is fixedly provided with a lower group rod 34 that extends to the bottom of the material unloading slide 2 as an integral whole, and the upper blocking rod 33 and the lower group rod 34 They are parallel to each other and perpendicular to the upper connecting rod 29 and the lower connecting rod 30 respectively. A through square hole 10 is opened on the bottom inner wall of the narrow slide 4 in the unloading slide 2 corresponding to the top of the lower group rod 34.

The length of the protrusion below the special-shaped turntable 31 is greater than half the thickness of the vacuum rice bag. That is, initially, the vertical spacing between the separating plate 35 at the bottom end of the upper blocking rod 33 and the inner wall of the bottom of the narrow slide 4 is smaller than the thickness of the vacuum rice bag, so that the vacuum rice bag falling into the narrow slide 4 can be blocked, and when the protruding portion below the special-shaped turntable 31 rotates upward and synchronously lifts and tilts the lower connecting rod 30 and the upper connecting rod 29, the separating plate 35 on the upper blocking rod 33 and the lower group rod 34 can be synchronously moved upward. At this time, the upper blocking rod 33 drives the separating plate 35 to move upward and can contact the first vacuum rice bag falling into the unloading slide plate 2, that is, the first vacuum rice bag can slide down along the narrow slide 4 and fall onto the material placing and cutting board 6, and at this time, the separating plate 35 on the lower group rod 34 is synchronously moved upward and inserted into the gap between the first bag and the second bag of vacuum rice bags, thereby blocking all the vacuum rice bags behind, that is, at this time only the frontmost vacuum rice bag can slide down and fall onto the material placing and cutting board 6.
[0050] Working principle: when the vacuum-heat-sealed vacuum rice bags are fed through the assembly line conveyor belt 1, the vacuum rice bags will fall into the unloading slide 2 in sequence, and when feeding through the assembly line conveyor belt 1, the staff only needs to point the protruding sealed edge of the vacuum rice bag toward the side of the unloading slide 2 where the concave platform 5 is provided. When the vacuum rice bag falls into the inclined unloading slide 2, it will first slide down along the wide slide 3, and the end of the vacuum rice bag away from the protruding sealed edge will contact the bending part where the wide slide 3 and the narrow slide 4 are connected. At this time, the vacuum rice bag will slide down along the bending part where the wide slide 3 and the narrow slide 4 are connected and enter the narrow slide 4, and because the width of the narrow slide 4 is The length of the bulging part of the vacuum rice bag is adapted, and the vacuum rice bags that slide down into the narrow slide 4 will be neatly arranged, that is, the two ends are aligned. When they continue to slide down into the material placement and cutting plate 6, the error of cutting the convex sealing edge of each vacuum rice bag can be reduced. At the same time, since the unloading slide plate 2 is provided with a concave platform 5 on one side corresponding to the narrow slide 4, the vertical distance between the top of the concave platform 5 and the bottom inner wall of the narrow slide 4 is less than half the thickness of the vacuum rice bag, the convex sealing edge of the vacuum rice bag can be located above the top of the concave platform 5 and arranged neatly in a horizontal shape, which can be beneficial to the subsequent cutting of the convex sealing edge of the vacuum rice bag, thereby improving the overall functionality and convenience of the device;
[0051] When the vacuum rice bags fall into the narrow slide 4 in sequence, the side of the first vacuum rice bag will contact the upper barrier plate 35 of the upper barrier rod 33 in the intermittent material discharge barrier mechanism 8, thereby blocking the first vacuum rice bag, and can block the subsequent vacuum rice bags that fall into the narrow slide 4 in sequence. At the beginning of cutting, the servo motor 2 32 can be driven to drive the special-shaped turntable 31 to rotate, and the special-shaped turntable 31 is large at the top and small at the bottom. After the special-shaped turntable 31 rotates half a circle, the special-shaped turntable 3 After the lower protrusion rotates upward, the lower connecting rod 30 and the upper connecting rod 29 are synchronously lifted and tilted, so that the upper blocking rod 33 and the material separation sheet 35 on the lower group rod 34 can be synchronously moved upward. At this time, the upper blocking rod 33 drives the material separation sheet 35 to move upward and can contact the first vacuum rice bag falling into the unloading slide plate 2. That is, the first vacuum rice bag can slide down along the narrow slide 4 and fall onto the material placement and cutting plate 6. At this time, the material separation sheet 35 on the lower group rod 34 is synchronously moved upward, and the first bag and the second bag are inserted into the vacuum rice bag. The vacuum rice bags are placed in the gaps between the empty rice bags, thereby blocking all the vacuum rice bags behind, that is, at this time, only the front vacuum rice bag can slide down onto the material placement and cutting plate 6. During the process of continuing to rotate half a circle, the special-shaped turntable 31 returns to its original state, that is, the lower connecting rod 30 and the semicircular ring member 28 as well as the upper blocking rod 33 and the lower group rod 34 return to their original state. At this time, the material separation sheets 35 on the upper blocking rod 33 and the lower group rod 34 move downward synchronously. After the material separation sheets 35 on the lower group rod 34 are completely moved down into the square hole 10, the narrow sliding 4 The gathered vacuum rice bags will continue to move down for a distance and then continue to be blocked by the material separation sheet 35 on the upper blocking rod 33, thereby stopping the unloading. During the continuous rotation of the special-shaped turntable 31, intermittent unloading can be completed, that is, each time a vacuum rice bag can be unloaded onto the material placement and cutting plate 6 through the unloading slide plate 2, and the easy-tear cutting operation can be completed through the edge sealing and cutting device 7, thereby adapting to the automation and practical rationality of the actual production process of the vacuum rice bags, and improving the functionality of the device;
[0052] When the vacuum rice bag transported on the assembly line conveyor belt 1 can be intermittently unloaded onto the material placement and cutting board 6 through the intermittent unloading blocking mechanism 8 on the unloading slide plate 2, at this time, since the end of the vacuum rice bag away from the protruding edge seal will always fit the side inner wall of the narrow slide 4 and the limiting partition 9, it is ensured that the vacuum rice bag on the material placement and cutting board 6 each time the material is unloaded will not have position deviation, and the specifications of the protruding edge seal of the vacuum rice bag are cut to be consistent each time, thereby improving the cutting quality of the edge seal easy tearing edge of the device;
[0053] After the vacuum rice bag falls onto the loading and cutting plate 6, since the outer walls on both sides of the loading and cutting plate 6 are flush with the inner walls on both sides of the narrow slide 4, and the cutting area in the edge sealing cutting device 7 corresponds to the concave platform 5 on one side of the unloading slide 2, and the height of the top of the protruding block 16 from the horizontal base plate 15 is the same as the vertical distance from the top of the concave platform 5 to the bottom inner wall of the narrow slide 4, the protruding edge sealing of the vacuum rice bag will be horizontally located above the protruding block 16. Initially, the cutting knife 21 and the protruding block 16 at the bottom of the cutting rotating ring 20 are spaced up and down. At this time, the driving servo motor 22 drives the rotating shaft 18 and the turntable 19 to rotate synchronously. Since the turntable 19 is eccentrically connected to the rotating shaft 18, the turning process of the turntable 19 will drive the cutting rotating ring 20 to perform an elliptical circular motion, and due to the effect of the limiting mechanism, that is, The L-shaped limit link 26 on the side of the cutting rotating ring 20 is limited by the limit slide 25. During the operation of the cutting rotating ring 20, the vertical section of the L-shaped limit link 26 can move up and down in the limit slide 25, and at the same time drive the limit slide 25 to move left and right on the limit cross bars 23 on both sides, so as to meet the movement trajectory of the cutting rotating ring 20, thereby ensuring that the cutting rotating ring 20 will not rotate, that is, the upper and lower spacing distances between the cutting rotating ring 20 and the protruding block 16 are changed, thereby driving the cutting knife 21 to move upward to cut the protruding sealing edge of the vacuum rice bag with the cutting groove of the protruding block 16. That is, after the servo motor 12 drives the rotating shaft 18 and the rotating disk 19 to rotate one circle, the cutting rotating ring 20 and the cutting knife 21 can be limited. Elliptical displacement, that is, the up and down displacement relative to the protruding block 16 is completed.
[0054] After the cutting operation of the easy-tear edge is completed, the two groups of connecting cross-base rods 12 can be driven to pull the two groups of L-shaped flip base members 13 to flip as a whole, so that the top horizontal parts of the two groups of L-shaped flip base members 13 can be tilted, that is, the cutting plate 6 can be unloaded after the cutting is tilted, and then the connecting cross-base rods 12 are driven to push the L-shaped flip base member 13 to restore to its original state, that is, the cutting plate 6 is restored to its horizontal original state. During the operation of the device, the rotation speed and time of the servo motor 2 32 to drive the special-shaped turntable 31 can be controlled according to actual conditions. Within the process time of controlling the special-shaped turntable 31 to rotate one circle, the cutting plate 6 needs to be restored to its original state after the tilting and the edge sealing cutting device 7 needs to complete the cutting operation, so as to meet the requirements of the unloading slide plate 2 and the intermittent unloading blocking mechanism 8 on the unloading slide plate 2 to slide only one vacuum rice bag onto the cutting plate 6 at a time, and unload the material after cutting.
