Abstract
Description
Technical Field
[0001] This utility model relates to the field of fully automatic paper bag processing technology, specifically to a patching mechanism and production line for an anti-tipping paper bag production line. Background Technology
[0002] Products from various sectors, including food delivery, shopping, commodity packaging, catering, and supermarkets, require paper bags for transportation during the packaging process. There are many types of paper bag packaging equipment in the industry, but their basic structural principles are the same. Paper bags are made by going through several steps, including roll making, cutting, gluing the bottom, and storage.
[0003] Industries with specific transportation needs, especially the food and beverage industry, face higher requirements for the packaging and transportation of beverages and takeout orders. Cup-shaped drinks, in particular, are prone to tipping and spilling during transport or delivery due to the limitations of existing paper bag structures. This not only inconveniences consumers but can also lead to unnecessary trouble and losses for businesses. Currently, paper bag products designed to prevent tipping have emerged, but these products are primarily handmade, making mass production impossible and resulting in very low production efficiency.
[0004] A production line for anti-tipping paper bags improves the paper bag manufacturing process by incorporating a fixed inner strip inside the paper bag to accommodate cup-shaped beverages. This significantly enhances the stability of beverages during transportation and effectively reduces tipping and spillage. This utility model relates to a patching mechanism for an anti-tipping paper bag production line. Summary of the Invention

The clamping plate mechanism and the gripper mechanism are located in the groove. The cutting mechanism includes: a cutting roller, a bushing, a connecting shaft, a cutting blade, a connecting rod three, and a cam three. The cutting roller is located on one side of the air suction roller.

[0010] Preferably, the gripper mechanism includes: a rotating tube, grippers, a second connecting rod, and a second cam; the rotating tube is hollow inside and rotatably mounted on the outer periphery of the rotating shaft; there are multiple grippers, evenly spaced on the rotating tube; one end of the rotating tube is in sliding contact with the second cam via the second connecting rod; the second cam is located at the other end of the suction roller shaft.
[0011] Preferably, the second cam has the same structure as the first cam, and the second cam and the first cam are asymmetrically arranged at both ends of the suction roller, offset by a certain angle.
[0012] Preferably, the gripper is L-shaped, and the gripper height is slightly greater than the clamping plate height.
[0013] Preferably, the surface of the suction roller is provided with a plurality of air holes, which are located on the suction roller near the groove opening.
[0014] Preferably, the clamps and grippers are wrapped with elastic rubber.
[0015] Preferably, the groove extends through both ends of the suction roller.

[0017] The beneficial effects of this utility model are:
[0018] 1. The patching mechanism of this utility model works in conjunction with the entire anti-tipping paper bag production line. The paper bags produced have an inner patch strip inside, which can fix cup-shaped beverages and prevent them from tipping over and spilling.

[0019] 2. The clamping plate mechanism and the gripper mechanism of this utility model work together to clamp the edge of the inner strip, preventing the inner strip from being pulled out when the cutting knife leaves the groove. At the same time, the gripper mechanism holds the entire inner strip to prevent it from curling up, which facilitates subsequent work.
[0020] 3. The inner strip of this utility model is folded into a double-layer structure. Compared with the general single-layer inner strip, the double-layer structure is more reinforced and provides more stable fixation for cup-shaped beverages. Attached Figure Description

[0033] Preferred embodiments of this utility model will be described in detail with reference to the accompanying drawings, which will make it easy for those skilled in the art to implement these embodiments. However, this utility model can also be implemented in various different forms, and therefore this utility model is not limited to the embodiments described below. In addition, for the purpose of more clearly describing this utility model, components not connected to this utility model will be omitted from the drawings.
[0034] Example 1:
[0035] like Figure 3 As shown, a patching mechanism for an anti-tipping paper bag production line includes: a paper pulling mechanism 1, a cutting mechanism 2, an air suction roller 3, a clamping plate mechanism 4, a gripper mechanism 5, and a cutting mechanism 6.
[0036] The paper pulling mechanism 1 is provided with a cutting mechanism 2 on one side, and a suction roller 3 is provided below the cutting mechanism 2. A clamping mechanism 4 and a gripper mechanism 5 are provided on the suction roller 3, and a cutting mechanism 6 is provided on one side of the suction roller 3.
[0037] The paper pulling mechanism 1 includes: a first paper pulling roller 11 and a second paper pulling roller 12; the first paper pulling roller 11 and the second paper pulling roller 12 are arranged at a certain distance from each other, and the first paper pulling roller 11 and the second paper pulling roller 12 are driven by a motor. One end of the first paper pulling roller 11 is connected to the motor, and the ends of the first paper pulling roller 11 and the second paper pulling roller 12 are respectively provided with gears, and the two gears mesh (the motor and gears are not shown); one end of the inner strip roll paper passes through the gap between the first paper pulling roller 11 and the second paper pulling roller 12; the paper pulling mechanism 1 is used to convey the inner strip roll paper;
[0038] The cutting mechanism 2 includes: a cutting roller 21 and a fixed lower blade 22; the cutting roller 21 is disposed on one side of the paper pulling roller 11, and the fixed lower blade 22 is disposed below the cutting roller 21; the cutting roller 21 is a structure with blades on a circular roller, and the cutting roller 21 is driven by a motor (motor not shown). The cutting mechanism 2 is used to cut the inner strip 7; when the blade on the cutting roller 21 rotates to the lower position, it contacts the fixed lower blade 22 and cuts the inner strip paper roll that passes between the cutting roller 21 and the fixed lower blade 22;
[0039] like Figure 4-5 As shown, the suction roller 3 is hollow inside and has a vacuum device (not shown). The suction roller 3 has air holes 31. The suction roller 3 is driven by a motor (not shown). A groove 32 is horizontally opened on one side of the suction roller 3. The groove 32 is parallel to the axis of the suction roller 3. The suction roller 3 adsorbs the cut inner strip 7 through the air holes 31.
[0040] like Figure 5-6 As shown, a clamping mechanism 4 and a gripper mechanism 5 are provided inside the slot 32; the clamping mechanism 4 includes: a rotating shaft 41, a clamping plate 42, a connecting rod 43, and a cam 44; the rotating shaft 41 is disposed inside the slot 32, and the clamping plate 42 is fixedly disposed on the rotating shaft 41. One end of the rotating shaft 41 is connected to the connecting rod 43, and one end of the connecting rod 43 slides in contact with the cam 44. The cam 44 is disposed at one end of the suction roller 3 shaft; as Figure 7 As shown, cam 44 includes: arc block 441 and arc block 442; arc block 441 is mounted on the shaft of suction roller 3, and arc block 442 is mounted on the side wall of arc block 441; one end of connecting rod 43 slides in contact with the top of arc block 442, wherein the middle of the top of arc block 442 is the highest point, and one side of the middle is a smooth ramp. One end of connecting rod 43 moves along the smooth ramp. When it passes the highest point of arc block 442, connecting rod 43 drives the rotating shaft 41 to rotate by a certain angle, thereby causing the clamping plate 42 to rotate by a certain angle, so that the clamping plate 42 clamps the edge of the inner strip 7.
[0041] The gripper mechanism 5 includes: a rotating tube 51, grippers 52, a second connecting rod 53, and a second cam 54. The rotating tube 51 is hollow inside and is mounted in a slot 32 via bearings, and is located on the outer periphery of a rotating shaft 41, which can rotate within the rotating tube 51. Multiple grippers 52 are evenly spaced on the rotating tube 51, and are located on one side of the clamping plate 42. A second connecting rod 53 is located at the end of the rotating tube 51 away from the first connecting rod 43, and one end of the second connecting rod 53 slides in contact with the second cam 54. The second cam 54 is located at the other end of the shaft of the suction roller 3, and has the same structure as the first cam 44. When the second connecting rod 53 passes the highest point of the second cam 54, the connecting rod... Rod 2 53 drives the rotating tube 51 to rotate at a certain angle, thereby causing the gripper 52 to rotate at a certain angle, and the gripper 52 clamps the inner strip 7 as a whole; the clamping plate mechanism 4 and the gripper mechanism 5 cooperate to clamp the inner strip 7; among them, cam 2 54 and cam 1 44 are asymmetrically arranged at both ends of the suction roller 3, offset by a certain angle. This arrangement ensures that during the rotation of the suction roller 3, the connecting rod 1 43 first passes through the highest point of cam 1 44, causing the clamping plate 42 to deflect and clamp the edge of the inner strip 7. Then, the connecting rod 2 53 passes through the highest point of cam 2 54, causing the gripper 52 to further clamp the inner strip 7 as a whole. This results in a clamping sequence with a certain time sequence.
[0042] like Figure 8 As shown, the slicing mechanism 6 includes: a slicing roller 61, bushings 62, a connecting shaft 63, a slicing blade 64, a connecting rod 65, and a cam 66. The slicing roller 61 is located on one side of the suction roller 3 and is driven by a motor (not shown). Bushings 62 are respectively provided at both ends of the slicing roller 61, and the connecting shaft 63 is rotatably mounted on the protrusions 621 of the bushings 62 at both ends. The connecting shaft 63 maintains a certain distance from the slicing roller 61. The slicing blade 64 is provided on the connecting shaft 63. The blade 64 is made of rubber; one end of the connecting shaft 63 is provided with a connecting rod 65, one end of which is slidably mounted on a cam 66, which is located at one end of the cutting roller 61; when the connecting rod 65 passes the highest point of the cam 66, it drives the connecting shaft 63 to rotate a certain angle, causing the cutting blade 64 to rotate a certain angle to separate from the groove 32; the cutting mechanism 6 is used to cut the inner strip 7 into the groove 32 of the suction roller 3, where the inner strip 7 is squeezed and folded.
[0043] like Figure 9 As shown, preferably, as one possible implementation, the gripper 52 is L-shaped, and the height of the gripper 52 is slightly greater than the height of the clamping plate 42. This arrangement allows the gripper 52 to cooperate with the clamping plate 42, better clamping the inner strip 7. The clamped inner strip 7 has a double-layer folded structure, as shown. Figure 9 As shown;
[0044] Preferably, as one possible implementation, the suction roller 3 is provided with a plurality of air holes 31 on its surface. The air holes 31 are located on the suction roller 3 near the groove 32. This arrangement allows the suction roller 3 to attract the inner strip 7 close to the groove 32, making it convenient for the subsequent cutting blade 64 to cut the inner strip 7 into the groove 32.
[0045] Preferably, as one possible implementation, the clamping plate 42 and the gripper 52 are wrapped with elastic rubber to prevent damage to the inner strip 7 when the clamping plate 42 and the gripper 52 are clamping;
[0046] Preferably, as one possible implementation, the slot 32 extends through both ends of the suction roller 3. This arrangement facilitates the compression and folding of inner strips 7 of different lengths, making the device more adaptable.
[0047] Example 2:
[0048] like Figure 1-2 As shown, this utility model also provides an anti-tipping paper bag production line, which includes the patching mechanism of an anti-tipping paper bag production line described in Embodiment 1, and further includes: a feeding mechanism, a traction mechanism, a correction mechanism, a handle-attaching mechanism, a tube-forming mechanism, a tearing mechanism, a bottom-gluing mechanism, a bag-sorting mechanism, and a sealing sticker-attaching mechanism arranged sequentially along the production line. In this production line, the feeding mechanism, traction mechanism, correction mechanism, handle-attaching mechanism, tube-forming mechanism, tearing mechanism, bottom-gluing mechanism, bag-sorting mechanism, and sealing sticker-attaching mechanism are all existing technologies of bag making machines. The handle-attaching mechanism can be removed or added according to actual needs. In this embodiment, the patching mechanism is located between the correction mechanism and the handle-attaching mechanism, and is located above the paper bag conveyor belt.
[0049] Working principle of this utility model:
[0050] The paper bag is conveyed forward through the feeding mechanism, traction mechanism, and correction mechanism. When the paper bag is conveyed to the bottom of the patch processing mechanism, the patch processing mechanism performs patch processing on the paper bag (applying the inner patch 7). Specifically, one end of the inner patch roll is conveyed forward through the paper pulling mechanism 1. When the inner patch 7 passes the cutting mechanism 2, the cutting mechanism 2 cuts the inner patch roll. The cut inner patch 7 is attracted by the suction roller 3. At this time, the suction roller 3 drives the inner patch 7 to rotate. At the same time, the cutting mechanism 6 rotates. The cutting blade 64 on the cutting mechanism 6 corresponds to the groove 32 in the suction roller 3 and cuts the inner patch 7 into the groove 32. Then, the connecting shaft 63, the connecting rod 65 and the cam 66 cooperate to make the cutting blade 64 rotate away from the groove 32.
[0051] Next, the rotating shaft 41 and connecting rod 43 of the clamping mechanism 4 cooperate with the cam 44 to cause the clamping plate 42 to rotate and clamp the edge of the inner strip 7. Subsequently, the rotating tube 51 and connecting rod 53 of the gripper mechanism 5 cooperate with the cam 54 to cause the gripper 52 to rotate and further clamp the inner strip 7. At this time, the inner strip 7 is clamped between the clamping plate 42 and the gripper 52. Figure 9 As shown;
[0052] Next, when the suction roller 3 rotates to the point where the slot 32 faces downwards, the rotating shaft 41, connecting rod 43, and cam 44 cooperate to release the clamp 42. The rotating tube 51, connecting rod 53, and cam 54 cooperate to release the gripper 52, and the inner label 7 is released and falls onto the paper bag below. Because the gap between the bottom of the suction roller 3 and the paper bag is very small, the suction roller presses the inner label onto the paper bag, adhering it to the paper bag (adhesive is applied to the corresponding position on the paper bag beforehand), thus completing the application of the inner label 7. Figure 10 As shown;
[0053] After the inner strip 7 is attached, the paper bag continues to be conveyed forward, and then the processes of attaching handles, forming into a tube, gluing the bottom, and sorting the bag are carried out in sequence.
