Description

Technical Field

[0001] This invention relates to the field of packaging bag processing technology, and in particular to a processing and production equipment and method for detachable insulated paper bags. Background Technology

[0002] With the popularization of environmental protection concepts and the advancement of waste sorting policies, the research and development of environmentally friendly packaging materials and related processing equipment has become a hot topic in the industry. Among them, detachable insulated paper bags are widely used in food transportation, daily shopping and other scenarios because they combine heat preservation performance and environmental recycling value. These paper bags belong to the composite environmentally friendly packaging structure. The outer layer uses high-strength paper to ensure the bag's shape and load-bearing strength, while the inner layer uses soft, thin heat preservation film or aluminum foil to achieve heat preservation function. The core design requirement is "detachable", that is, users can easily tear the outer paper and the inner heat preservation film / aluminum foil after use, so as to classify and recycle them separately, avoiding resource waste or environmental pollution caused by mixed packaging waste.

[0003] However, the production process of detachable insulated paper bags presents a significant structural contradiction: on the one hand, to ensure the smooth progress of subsequent folding and forming processes, the outer paper and the inner insulation film / aluminum foil need to be tightly bonded during the production stage to prevent problems such as slippage and wrinkles of the inner material during processing, thus ensuring the precision of bag forming; on the other hand, to meet the need for separate recycling after use, the two cannot be completely glued together, and conditions for easy separation need to be reserved.

[0004] Existing composite paper bag processing equipment cannot solve the above contradictions. It generally adopts a full-page adhesive coating process, which achieves the bonding and fixation of the two by coating the entire surface of the paper or film with adhesive. Although this process can ensure the tightness of the bonding of the composite materials and meet the molding and processing requirements, it will cause the outer paper and the inner insulation film / aluminum foil to be completely fused together. After use, the two cannot be effectively separated and can only be incinerated as dry waste. This not only violates the original intention of environmentally friendly packaging design, but also wastes resources such as paper and insulation film. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings in the prior art by providing a processing and production equipment and method for detachable insulated paper bags.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A processing and production equipment for detachable insulated paper bags, comprising: Support frame; The unwinding guide mechanism includes an unwinding roller rotatably mounted on one side of the support frame, a motor II for driving the unwinding roller, multiple guide rollers, and a web correction adjustment module. The thermal insulation film bag is wound around the unwinding roller and sequentially passes through the multiple guide rollers and the web correction adjustment module. The transplanting and dispensing mechanism includes a transplanting and conveying module disposed above the carrier frame, a mounting base driven by the transplanting and conveying module, a plurality of vacuum suction cups disposed on the mounting base, and a dispensing mechanism fixed to the bottom of the transplanting and conveying module. The dispensing mechanism includes a U-shaped carrier frame, with dispensing valves II respectively installed at both ends of the U-shaped carrier frame, and a plurality of dispensing valves I arranged along the width direction in the middle. The dispensing valves I and dispensing valves II constitute a dispensing assembly for coating U-shaped glue lines on the cardboard. The origami forming mechanism is located on one side of the carrier frame and below the transplanting and conveying module. It includes a support carrier plate and two flip-adjustable plates that can flip in opposite directions. The support carrier plate is used to support the glued cardboard and the insulation film bag above it, which are transferred by the transplanting and conveying module. The flip-adjustable plates are used to fold the cardboard over the insulation film bag, so that the U-shaped glue line glues the two ends and the two end areas of the cardboard to the insulation film bag in the width direction, while the large area in the middle of the two remains unbonded and separable.

[0007] As a further improvement to the above technical solution: The origami forming mechanism further includes: Support frame II is fixed to the bearing frame; Two cylinders III are mounted on the top of the support frame II; A lifting adjustment plate is connected to the output end of cylinder III; Two rotating seats II are fixed to the lifting adjustment plate; The rotating spindle is rotatably connected between the two rotating seats II, and the flip adjustment plate is fixed on the rotating spindle; A transmission gear is fixedly sleeved on one end of the rotating spindle; The guide core rod is fixed to one side of the rotating seat II; The rack mounting bracket is slidably sleeved on the two guide core rods and meshes with the two transmission gears; Additionally, cylinder II is fixed to the lifting adjustment plate, and its output end is connected to the rack mounting bracket, which drives the rack mounting bracket to slide along the guide core rod, thereby driving the two flip adjustment plates to flip synchronously in opposite directions through the transmission gear and the rotating core shaft.

[0008] It also includes two support frames I fixed to the carrier frame, and the support bearing plate is fixed to the top of the two support frames I and located between the two tilting adjustment plates.

[0009] The transplanting and conveying module is also equipped with a lifting and adjusting module. The bottom of the lifting and adjusting module is fixed with a pressure plate. When the cardboard and the heat preservation film bag are placed on the support bearing plate, the lifting and adjusting module can drive the pressure plate to press down, press the two together and position them before bending.

[0010] It also includes an extrusion molding module, which is disposed downstream of the origami forming mechanism and includes: Two rotating seats I are fixed on the support frame; The drive roller is rotatably connected between the two rotating seats I; Motor I is installed inside the support frame, and its output end is connected to the drive roller; A pressing roller is located above the drive roller; Additionally, a lifting drive component is provided on the rotating seat I, used to drive the pressing roller to approach or move away from the drive roller, so as to squeeze the folded insulation film bag and cardboard that pass through it, so as to cure and bond the U-shaped adhesive line.

[0011] The lifting drive component includes a sliding block slidably disposed within the rotating seat I and a cylinder I fixed to the top of the rotating seat I. The output end of the cylinder I is connected to the sliding block, and the pressing roller is rotatably connected between the two sliding blocks.

[0012] The widths of the two flip adjustment plates are set to be one wide and one narrow, so that after bending and forming, the narrower side flip portion is located below the wider side flip portion.

[0013] It also includes a material carrier platform for stacking multiple cardboards. The material carrier platform is fixed on the carrier frame and located below the starting end of the moving path of the transfer conveying module. The material carrier platform is provided with limiting posts for positioning the stacked cardboards.

[0014] A production method based on the above-mentioned processing equipment includes the following steps: S1. The heat-insulating film bag is unwound by the unwinding roller, and then guided by the guide roller and corrected by the correction adjustment module before being conveyed to the support plate of the folding forming mechanism. S2. The transfer and conveying module drives the vacuum suction cup to pick up a cardboard from the material carrier platform; S3. The dispensing mechanism is activated, and dispensing valve I and dispensing valve II apply U-shaped glue lines to the bonding surfaces of the cardboard. S4. The transfer and conveying module transfers the glued cardboard to the corresponding position of the thermal insulation film bag located on the support plate. S5. The lifting and adjusting module drives the pressure plate to press down, pressing the cardboard and the thermal insulation film bag tightly onto the support plate. S6. The cylinder II of the folding forming mechanism drives the two flipping adjustment plates to flip in opposite directions, covering the cardboard onto the thermal insulation film bag, so that the U-shaped glue line area is bonded. S7. The bent semi-finished product is conveyed to the extrusion molding module, where the bonded parts are cured under the pressure of the drive roller and the pressing roller. S8. Cut the continuously formed composite bag into individual separable insulated paper bags.

[0015] Beneficial effects: In this invention, the processing and production equipment for detachable insulated paper bags includes a folding and forming mechanism in which two flipping adjustment plates are set with different widths to ensure that one end of the cardboard is below the other end after folding, thus improving the bending and forming effect. The cylinder II drives the rack mounting bracket to slide along the guide core rod, causing the transmission gear and rotating core shaft to move synchronously, achieving precise bending of both sides of the cardboard by the flipping adjustment plates. Combined with the lifting adjustment module driving the rubber pressure plate to press the cardboard, material displacement during bending is prevented, ensuring that the bending marks are consistent with the preset values. Simultaneously, the cylinder III drives the lifting adjustment plate to rise and fall, changing the initial height of the flipping adjustment plate until it is parallel to the supporting bearing plate, meeting the complete folding requirements of different cardboard sizes and improving the equipment's versatility. In this invention, the processing and production equipment for a detachable thermal insulation paper bag has a glue dispensing mechanism fixed by a U-shaped support frame. The glue dispensing valve I is started once, and the glue dispensing valve II is started intermittently multiple times, so that the glue droplet outline is U-shaped, accurately covering both ends of the cardboard in the width direction and the bonding area with the thermal insulation film bag, providing a reliable bonding foundation for the two to be tightly bonded. Moreover, the bonding position is at both ends of the thermal insulation film bag, while there is no bonding in the middle, which facilitates subsequent recycling. In this invention, the processing and production equipment for detachable insulated paper bags automatically picks up and places paperboards by using a transfer and conveying module to drive the mounting base and vacuum suction cups, eliminating the need for manual handling and positioning. The paper folding, gluing, and pressing processes are automatically completed through the sequential linkage of various cylinders and motors, forming a continuous processing flow of "unwinding-guiding and correction-material picking and gluing-bending-pressing-slitting". The processes are seamlessly connected, greatly reducing manual intervention, which not only improves production efficiency but also avoids errors caused by manual operation, ensuring the consistency of product quality. It is especially suitable for mass production scenarios and can effectively reduce the labor cost investment of enterprises. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Example 1 Reference Figures 1-9A processing and production equipment for detachable insulated paper bags, used in the packaging bag processing field, includes: a support frame 1, which serves as the installation foundation and main support of the entire equipment. The support frame 1 is made of high-strength aluminum alloy and provides a stable installation benchmark for each component, ensuring no significant vibration during equipment operation. An unwinding roller 2 is horizontally and rotatably mounted on the left side of the support frame 1. Both ends of the unwinding roller 2 are connected to the side walls of the support frame 1 via deep groove ball bearings, ensuring smooth rotation and low friction. A motor II 13 is bolted to the mounting cavity inside the support frame 1. Its output end is fixedly connected to one end of the unwinding roller 2 via a flexible coupling. The flexible coupling effectively buffers the impact force during motor startup, preventing excessive instantaneous force on the unwinding roller 2 and thus avoiding damage to the insulated film bag 3. The thermal insulation film bag 3 is fitted onto the outer wall of the unwinding roller 2. The outer wall of the unwinding roller 2 has annular limiting bosses circumferentially positioned, with the spacing between the bosses matching the width of the thermal insulation film bag 3 to prevent the bag from shifting axially along the unwinding roller 2 during unwinding. In use, motor II13 starts, and its output torque is transmitted to the unwinding roller 2 via a flexible coupling, causing the unwinding roller 2 to rotate around its own axis, thus achieving smooth unwinding of the thermal insulation film bag 3. The unwinding speed can be adjusted through the control system of motor II13 to adapt to different production rhythms.

[0020] Multiple guide rollers 4 are rotatably mounted on the left side of the carrier frame 1 via bearing seats, evenly arranged along the conveying direction of the thermal insulation film bag 3. The surface of each guide roller 4 is polished to reduce frictional damage to the surface of the thermal insulation film bag 3. The installation height of the guide rollers 4 is adjusted sequentially to form a smooth conveying channel, ensuring that the thermal insulation film bag 3 is taut but not stretched during conveying. The correction adjustment module 7 is fixed to the top of the carrier frame 1 by bolts, located downstream of the guide rollers 4. The correction adjustment module 7 has built-in photoelectric sensors and micro cylinders, which can detect the edge position of the thermal insulation film bag 3 in real time. When the thermal insulation film bag 3 is detected to be off-center, the micro cylinder immediately actuates, pushing the correction roller to adjust the angle, correcting the off-center amount of the thermal insulation film bag 3 to a reasonable range, ensuring the accuracy of subsequent bonding and bending processes. After one end of the thermal insulation film bag 3 is released from the unwinding roller 2, it is sequentially wound around the multiple guide rollers 4 and the correction rollers of the correction adjustment module 7 to form a stable conveying path.

[0021] The material carrier platform 5 is welded to the right side of the carrier frame 1. The platform surface is made of stainless steel and has a smooth, flat surface. Multiple rectangular limit posts are arranged on the material carrier platform 5 and are fixed to the platform surface by threaded connections. The spacing between adjacent limit posts is adapted to the size of the cardboard 6. Multiple cardboard pieces 6 are neatly stacked on top of the material carrier platform 5 and positioned between the limit posts. The limit posts effectively prevent the cardboard pieces 6 from tipping over or shifting during stacking and handling, ensuring accurate positioning of the transfer conveyor module 9 when picking up materials.

[0022] The folding and forming mechanism 14 is installed on the right side of the carrier frame 1, parallel to the material carrier platform 5. Two support frames I 141 are symmetrically fixed to the right side wall of the carrier frame 1 by bolts, and the support carrier plate 142 is horizontally fixed to the top of the two support frames I 141. Support frame II 143 is also fixed to the right side wall of the carrier frame 1, located between the two support frames I 141. Two cylinders III 1412 are fixed to its top by bolts. The output end of cylinders III 1412 is fixed to the lifting adjustment plate 144 by threaded connection. The lifting adjustment plate 144 is made of steel plate to ensure structural strength. Two rotating seats II 145 are symmetrically fixed to the top of the lifting adjustment plate 144. The rotating spindle 146 is rotatably installed between the two rotating seats II 145 by bearings. Two flip adjustment plates 147 are fixed to the outer wall of the rotating spindle 146 by flat keys, symmetrically distributed on both sides of the support carrier plate 142. The width of the flip adjustment plates 147 is set to be large and small respectively to ensure that after folding, the cardboard end on one side is below the cardboard end on the other side. One end of the rotating spindle 146 is fixedly fitted with a transmission gear 1411 via a flat key. A guide rod 1410 is bolted to one side of the rotating seat II 145, and the guide rod 1410 is perpendicular to the rotating spindle 146. A rack mounting bracket 148 is slidably fitted onto the outer wall of the two guide rods 1410, and its bottom rack meshes with both transmission gears 1411, ensuring smooth transmission without jamming. Cylinder II 149 is fixed to the bottom of one of the lifting adjustment plates 144 via a bracket, and its output end is fixedly connected to the rack mounting bracket 148 via a floating joint. The floating joint compensates for installation errors and prevents lateral force from being generated when cylinder II 149 operates. After the cardboard 6 is placed on the support plate 142, cylinder II 149 is activated, and the output end pushes the rack mounting bracket 148 to slide horizontally along the guide core rod 1410. The rack drives the two transmission gears 1411 to rotate synchronously, which in turn drives the rotating core shaft 146 to rotate. Finally, it drives the two flip adjustment plates 147 to flip towards the support plate 142, so as to achieve precise bending of the two sides of the cardboard 6. At the same time, the cylinder III 1412 drives the lifting adjustment plate 144 to rise and fall, changing the initial height of the flip adjustment plate 147 to ensure that the cardboard 6 is completely folded.

[0023] The transfer conveying module 9 is bolted to the top crossbeam of the support frame 1, located directly above the folding and forming mechanism 14, enabling precise linear reciprocating motion. The output end of the transfer conveying module 9 is bolted to the mounting base 16, which is a rectangular steel plate. Multiple vacuum suction cups 17 are fixed through the top of the mounting base 16, evenly distributed at appropriate positions. The suction ports of the suction cups are connected to an external vacuum pump via air pipes to ensure stable adsorption of the cardboard 6. During operation, the transfer conveying module 9 moves the mounting base 16 directly above the material support platform 5. The mounting base 16 then descends, and the vacuum suction cups 17 contact and adsorb the uppermost cardboard 6. The mounting base 16 then rises, and the transfer conveying module 9 moves the cardboard 6 directly above the supporting support plate 142. Finally, the mounting base 16 descends, the vacuum suction cups 17 break the vacuum, and the cardboard 6 is stably placed on the supporting support plate 142.

[0024] The lifting adjustment module 10 is bolted to the output end side of the transplanting and conveying module 9 and is set parallel to the mounting base plate 16. The pressure plate 11 is bolted to the bottom end of the lifting adjustment module 10. The pressure plate 11 is made of rubber to avoid damaging the insulation film bag 3, and its size is adapted to the support plate 142. When the cardboard 6 is placed on the support plate 142, the lifting adjustment module 10 drives the pressure plate 11 to descend, pressing the cardboard 6 firmly onto the support plate 142 to prevent the cardboard 6 from shifting during bending. At the same time, it ensures that the bending mark is the same as the preset mark. After bending to 90°, the pressure plate 11 rises back to its original position, and the cardboard 6 continues to bend.

[0025] The dispensing mechanism is installed at the bottom of the transfer conveying module 9, above the mounting base plate 16. A U-shaped support frame 15 is bolted to the bottom frame of the transfer conveying module 9, with its opening facing the support plate 142, corresponding to the material support platform 5. A dispensing valve II 19 is bolted to each end of the U-shaped support frame 15, and multiple dispensing valves I 18 are evenly fixed in the middle. Each dispensing valve is connected to an external glue tank via a glue tube to ensure stable glue delivery. When the cardboard 6 is suctioned upwards by the vacuum suction cup 17, dispensing valves I 18 and II 19 are activated according to a preset program (multiple dispensing valves I 18 are activated once, and dispensing valves II 19 are activated intermittently multiple times), resulting in a U-shaped glue droplet profile, ensuring the firmness of the cardboard 6 at both ends in the width direction and when it is bonded to the insulation film bag 3.

[0026] Example 2 Reference Figures 1-9This is a processing and production equipment for detachable insulated paper bags. An extrusion molding module 8 is installed at the right end of the support frame 1, downstream of the folding and forming mechanism 14, and is used to press and fix the insulated film bag 3 to the cardboard 6 after gluing. Two rotating seats I 81 are symmetrically welded to the side walls of the support frame 1. A drive roller 82 is rotatably mounted between the two rotating seats I 81 via bearings. The surface of the drive roller 82 is covered with a rubber layer to increase friction with the material and prevent damage. A motor I 12 is bolted to the mounting cavity inside the support frame 1. Its output end is connected to one end of the drive roller 82 via a coupling, ensuring that the rotational speed of the drive roller 82 is synchronized with the unwinding speed of the insulated film bag 3. Vertical guide grooves are provided inside both rotating seats I 81, and sliding blocks 83 are slidably embedded in the guide grooves to ensure smooth and unobstructed movement of the sliding blocks 83. The top of the rotating base I81 is fixed to the cylinder I84 via a bracket, and its output end is fixed to the top of the sliding block 83 via a threaded connection. The pressing roller 86 is rotatably mounted between the two sliding blocks 83 via bearings, located directly above the drive roller 82. The structure of the pressing roller 86 is the same as that of the drive roller 82 to ensure uniform force during pressing. During operation, based on the total thickness of the thermal insulation film bag 3 and the cardboard 6 after lamination, the cylinder I84 drives the sliding block 83 to rise and fall along the guide groove, adjusting the distance between the pressing roller 86 and the drive roller 82. After the motor I12 starts, it drives the drive roller 82 to rotate via the synchronous belt. The heat-insulating film bag 3 and cardboard 6 after being glued are transported between the pressing roller 86 and the drive roller 82. Under the squeezing action of the two, the glue spreads evenly and achieves tight bonding. The bonded product is free of defects such as bubbles and glue separation. At the same time, a protective cover 85 is hinged to the top of the support frame 1, which covers the drive roller 82 and the pressing roller 86.

[0027] The specific working principle is as follows: First, after motor II13 starts, its output torque is transmitted to unwinding roller 2 through a flexible coupling, causing unwinding roller 2 to rotate smoothly around its own axis. The insulation film bag 3, which is sleeved on unwinding roller 2, is then unwound at a uniform speed. The annular limiting boss on the outer wall of unwinding roller 2 can prevent the insulation film bag 3 from shifting axially, ensuring a stable unwinding posture.

[0028] The released thermal insulation film bag 3 is sequentially wound onto multiple guide rollers 4, so that the thermal insulation film bag 3 is always in a taut but not stretched state. When the thermal insulation film bag 3 is conveyed to the correction adjustment module 7, its built-in photoelectric sensor detects the edge position of the thermal insulation film bag 3 in real time. If a deviation is detected, the micro cylinder immediately moves to push the correction roller to finely adjust the angle, correcting the deviation of the thermal insulation film bag 3 to a reasonable range, laying the foundation for the subsequent precise bonding with the cardboard 6.

[0029] At the same time, after the transfer and conveying module 9 is started, it drives the mounting base plate 16 to perform linear reciprocating motion. When the mounting base plate 16 moves directly above the material carrying platform 5, the mounting base plate 16 descends, and the multiple vacuum suction cups 17 fixed on it come into contact with the uppermost cardboard 6. The external vacuum pump is started to generate negative pressure on the suction cups. At the same time, the elastic positioning protrusions (not shown) provided on the bottom edge of the mounting base plate 16 fit and limit the corners of the cardboard 6, stably adsorbing and fixing the cardboard 6 to prevent it from shifting or falling off during the picking and placing process. After the cardboard 6 is stably adsorbed and fixed, the mounting base plate 16 rises, causing the cardboard 6 to move below the dispensing mechanism.

[0030] Multiple dispensing valves I18 are activated once, and the transfer and conveying module 9 moves the adsorbed cardboard 6 to directly above the support plate 142. During the movement, dispensing valve II19 is activated intermittently multiple times, making the outline of the glue droplet U-shaped. At the same time, one side of the cardboard 6 is inserted between the heat preservation film bag 3 and the support plate 142 until it moves directly above the support plate 142. Then, the mounting base 16 descends, the vacuum adsorption suction cup 17 breaks the vacuum, and the cardboard 6 is placed stably on the support plate 142.

[0031] After the cardboard 6 is placed, the folding mechanism 14 starts to perform the bending operation. First, the lifting adjustment module 10 drives the pressure plate 11 to descend, and the pressure plate 11 presses the upper surface of the insulation film bag 3 until the insulation film bag 3 and the cardboard 6 are squeezed onto the support plate 142. Then, the cylinder II 149 is activated, and its output end pushes the rack mounting bracket 148 to slide vertically along the guide core rod 1410. When the rack mounting bracket 148 slides, it drives the two transmission gears 1411 to rotate synchronously, which in turn drives the rotating spindle 146, which is fixedly connected to the transmission gears 1411, to rotate. This drives the flipping adjustment plate 147, which is fixed on its outer wall, to flip towards the support plate 142, so as to achieve precise bending of both sides of the cardboard 6. After bending 90°, the lifting adjustment module 10 drives the pressure plate 11 to rise, and at the same time, the cylinder III 1412 is activated to drive the lifting adjustment plate 144 to rise and fall, changing the initial height of the flipping adjustment plate 147 until the flipping adjustment plate 147 is parallel to the support plate 142, and the bending is completed.

[0032] Subsequently, motor I12 starts and drives the drive roller 82 to rotate via the coupling. It works with the pressing roller 86 to transport the thermal insulation film bag 3. The bonded material enters between the pressing roller 86 and the drive roller 82. Under the squeezing action of the two, the glue spreads evenly, achieving a tight bond between the thermal insulation film bag 3 and the cardboard 6. Finally, it is cut by the subsequent cutting mechanism to complete the processing of the detachable thermal insulation paper bag.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
