[0002] Storage boxes are already very common on the market. They are low-cost, widely beneficial, and highly suitable for general use, resulting in numerous brands of storage boxes. In modern society, storage boxes have gradually evolved into boxes similar to "storage boxes," boxes for storing things. Fabric storage boxes are trendy, convenient, practical, and space-saving, allowing for easy storage of various small items such as clothing. They are also stackable and easy to fold and unfold, allowing for flexible assembly and disassembly, saving space and making home life more convenient, comfortable, and tidy.

[0003] When making storage boxes from fabric, hard boards need to be inserted around the storage bag to support the periphery of the storage bag to form a box-like structure.

Detailed implementation manners

[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0036] Referring to Figure 1-13 , a continuous rigid plastic board plugging device for the production of storage boxes, includes two groups of plugging devices and a bag feeding device. Each group of plugging devices includes an equipment support 1. A board storage mechanism 8 is installed on the top of the equipment support 1, and a supplementary box 5 is installed on the top of the board storage mechanism 8. A guide plate mechanism 12 is arranged at the bottom of the board storage mechanism 8, and a push board 6 is slidably installed above the board storage mechanism 8. The push board 6 is located directly above the guide plate mechanism 12. Limit supports 3 are installed at both ends of the board storage mechanism 8, and a plug board driving mechanism 4 is installed between the two limit supports 3. The push board 6 is installed at the upper end of the plug board driving mechanism 4. Two deviation rectifying mechanisms 2 are installed at the bottom of the plug board driving mechanism 4. An opening mechanism 13 is installed at the middle position of the equipment support 1;

[0037] The bag feeding device includes a plurality of feeding oil cylinders 9 installed on a rotatable platform frame, and the bag feeding device is arranged between the two groups of plugging devices. A rotating motor 7 is installed at the front end of the feeding oil cylinder 9. A vertically arranged electric push rod 10 is installed at the bottom end of the rotating motor 7. A bag supporting mechanism 11 is fixedly installed at the bottom of the electric push rod 10. Two groups of bag mouth corner fixing support components are arranged at the four corners of the bag supporting mechanism 11, and suction head assemblies 115 for fixing the inner fabric of the storage bag are arranged around the bag supporting mechanism 11.

[0038] In the present invention, the bag-supporting mechanism 11 is mounted on a rotatable platform through an electric push rod 10, a rotating motor 7 and a feeding oil cylinder 9. Two groups of plugboard devices are installed at the peripheral positions of the platform. The two groups of plugboard devices respectively perform plugboard operations on the side plates and end plates of the storage box. The storage bag is opened and fixed at the lower position of the bag-supporting mechanism 11, and the four corner positions of the bag mouth are kept consistent with the four corner positions of the bag-supporting mechanism 11. Each group of bag-opening components respectively clamp and fix the side edge and end edge of the bag mouth. A corresponding storage board mechanism 8 and a guide board mechanism 12 are provided in the plugboard device. When inserting the side plate, the feeding oil cylinder 9 horizontally pushes the storage bag to the lower position of the guide board mechanism 12 to enter the plugboard station. The bag-supporting mechanism 11 immediately retracts the two bag-opening components close to the plugboard device, releases the edge of the side of the storage bag to be plugged, and the opening mechanism 13 approaches the outer side of the storage bag. Then, the opening mechanism 13 and the suction head assembly 115 move synchronously to both sides, thereby separating the outer layer fabric and the inner layer fabric on the side of the storage bag. Subsequently, the electric push rod 10 drives the bag-supporting mechanism 11 to move upward, inserts the guide board mechanism 12 into the plugboard gap between the outer layer fabric and the inner layer fabric, and then the guide board mechanism 12 moves to both ends of the plugboard gap to completely open the outer layer fabric and the inner layer fabric. Then, the plugboard driving mechanism 4 drives the push board 6 and the deviation rectifying mechanism 2 to act synchronously. The push board 6 pushes the hard plastic board at the front end of the storage board mechanism 8 downward, and the hard plastic board is directly inserted between the outer layer fabric and the inner layer fabric from the middle of the guide board mechanism 12. When the hard plastic board is inserted to the bottom end of the storage bag, the upper layer of the deviation rectifying mechanism 2 contacts the bottom position of the storage bag, uses the elasticity of the deviation rectifying mechanism 2 to provide positioning for both ends of the bottom of the hard plastic board, and gives a signal for the hard plastic board to be inserted to the set position. Then, the plugboard driving mechanism 4 drives the push board 6 to move upward. After the plugboard operation on one side is completed, the electric push rod 10 drives the bag-supporting mechanism 11 to move downward, and the guide board mechanism 12 is separated from the plugboard gap between the outer layer fabric and the inner layer fabric on the side of the storage bag. The bag-supporting mechanism 11 immediately resets the two bag-opening components close to the plugboard device to fix the bag mouth of the storage bag on the side where the hard plastic board is inserted. Then, the rotating motor 7 drives the bag-supporting mechanism 11 to rotate half a circle to perform the plugboard operation on the other side of the storage bag. After the insertion of the side plate is completed, it is switched to the insertion station of the end plate, and the same steps are used to perform the insertion operation on the end plate, thereby realizing the continuous plugboard operation of the storage bag, shortening the production time of the storage box, improving the production efficiency, and at the same time, ensuring that the insertion depths of the hard plastic boards around the storage box are consistent and improving the quality control effect of the storage box.

[0039] As a further solution in the present invention, the plate storage mechanism 8 includes a plate storage box 81, and an outlet slot 86 adapted to the push plate 6 is provided at the front end of the plate storage box 81. A supplementary oil cylinder 84 is installed at the rear end of the plate storage box 81, and a plate feeding assembly is installed at the front end of the supplementary oil cylinder 84. In the present invention, a plurality of rigid plastic plates are arranged in the plate storage box 81. The plate feeding assembly cooperates with the supplementary oil cylinder 84 to form a magazine-type plate feeding structure, which pushes the rigid plastic plates towards the outlet slot 86. When the push plate 6 inserts the outermost rigid plastic plate into the storage bag and then resets upward, the subsequent rigid plastic plates move forward accordingly for timely replenishment.

[0040] As a further solution in the present invention, the plate feeding assembly includes a U-shaped plate feeding member 83 and a push spring 85 installed between the plate feeding member 83 and the supplementary oil cylinder 84. A feeding port 82 communicating with the supplementary box 5 is provided at the top of the plate storage box 81. In the present invention, by providing a push spring 85 between the plate feeding member 83 and the supplementary oil cylinder 84, a dynamically stable thrust is set between the plate feeding member 83 and the rigid plastic plates, improving the stability during the process of the push plate 6 pushing out the rigid plastic plates. Secondly, the U-shaped plate feeding member 83 provides support for the rigid plastic plates in the supplementary box 5. When the plates in the plate storage box 81 are lacking, the rigid plastic plates in the supplementary box 5 directly fall into the plate storage box 81 from the rear end of the plate feeding member 83 to the rearmost end, enabling quick replenishment of the rigid plastic plates.

[0041] As a further solution in the present invention, the plate inserting driving mechanism 4 includes an upper movable frame 43 and a lower movable frame 45 slidably installed between two limiting brackets 3, and two driving push rod motors 41 installed on the limiting brackets 3. The upper movable frame 43 is installed at the top of the driving push rod motor 41, and a T-shaped transmission part 42 is provided at the front end of the upper movable frame 43. The push plate 6 is installed at the bottom end of the transmission part 42;

[0042] The plate inserting driving mechanism 4 further includes a transmission gear 44 rotatably installed on the limiting bracket 3, and transmission racks meshing with the transmission gear 44 are provided on the surfaces of the upper movable frame 43 and the lower movable frame 45. In the present invention, when the driving push rod motor 41 drives the upper movable frame 43 to move downward and the push plate 6 inserts the rigid plastic plate into the storage bag, through the transmission cooperation of the transmission gear 44 and the transmission racks, the lower movable frame 45 is driven to move upward synchronously with the deviation rectifying mechanism 2 to perform balancing and limiting operations on the two bottom ends of the rigid plastic plate, thereby ensuring the consistency and stability of the insertion depth of the rigid plastic plate.

[0043] As a further solution in the present invention, the correction mechanism 2 includes a positioning rod 21 fixedly mounted on the lower movable frame 45, and a T-shaped bracket 22 slidably mounted on the positioning rod 21. A spring 23 is also installed between the T-shaped bracket 22 and the positioning rod 21. In the present invention, when the hard plastic plate is inserted into the bottom of the storage bag, the T-shaped bracket 22 is located at the edge of the storage bag. The two T-shaped brackets 22 provide positioning and support for the two ends of the hard plastic plate, thereby avoiding the separation of the storage bag and the bag-supporting mechanism 11 when the hard plastic plate is inserted, and ensuring the insertion depth of the hard plastic plate.

[0044] As a further solution of the present invention, the bag-opening mechanism 11 includes a mounting base 111, and the opening assembly is mounted at the four corners of the mounting base 111. The opening assembly is composed of an outer presser foot 113 and an inner presser foot 114. Four diagonally distributed lower actuators 116 are mounted at the bottom of the mounting base 111, and a stepping motor is installed inside the lower actuator 116 to drive the inner presser foot 114 to extend and retract.

[0045] Two upper actuators 112 are installed on the top of the mounting base 111 , and a motor-driven retractable L-shaped movable block is provided around the upper actuator 112 . A cylinder is installed on the L-shaped movable block to drive the outer pressure foot member 113 to move up and down.

[0046] In the present invention, the bag opening of the storage bag is fixed at the outer side of the bag-stretching mechanism 11, and the four inner corners of the bag opening of the storage bag are respectively stretched open by a pair of triangular-shaped inner presser feet 114. The outer side of the storage bag is fixed by eight outer presser feet 113 distributed at the four corners, and then the four corners of the bag opening of the storage bag are clamped and fixed by the outer presser feet 113 and the inner presser feet 114. Each time the plate is inserted, the two outer presser feet 113 located on the outer side of the plate first move upward, and then move inward to separate from the outside of the storage bag. The two inner presser feet 114 located on the inner side of the plate shrink inward and separate from the inside of the storage bag, making room for insertion and guidance for the guide plate mechanism 12.

[0047] As a further solution in the present invention, a central actuator that drives the telescopic movement of four suction head assemblies 115 is installed in the center of the bottom of the mounting base 111, and the suction head assembly 115 is composed of a negative pressure tube and a suction head. The negative pressure tube is connected to a vacuum pump, and the suction head is arranged between the two support assemblies. In the present invention, the suction head assembly 115 cooperates with the opening mechanism 13 to contact the surface of the outer layer of fabric and the inner layer of fabric on the side of the storage bag respectively. When the suction head assembly 115 and the opening mechanism 13 retract in the opposite direction, the outer layer of fabric and the inner layer of fabric can be pulled apart, and then the opening formed by the outer layer of fabric and the inner layer of fabric can be unfolded, which is convenient for the insertion action of the guide plate mechanism 12.

[0048] As a further solution in the present invention, the opening mechanism 13 includes a horizontally arranged opening electric push rod 131 and a pulling block 132 arranged at the front end position of the opening electric push rod 131. The front end position of the pulling block 132 is installed with an arc-shaped expansion piece 133, and the two end surfaces of the expansion piece 133 are provided with arc-shaped elastic sheets 134. In the present invention, the suction head assembly 115 and the opening mechanism 13 are close to each other, and the expansion piece 133 expands to both ends under the thrust of the suction head assembly 115. At this time, the elastic sheet 134 is deformed under pressure and thus adheres to the outer surface of the storage bag, and the suction head assembly 115 is in the middle and uses negative pressure to absorb the inner surface of the storage bag. When the suction head assembly 115 and the opening mechanism 13 are synchronously moved away from the surface of the storage bag, the expansion piece 133 contracts, gathering the outer surface of the storage bag to the middle, and the suction head assembly 115 uses suction to drag the inner surface of the storage bag inward, thereby forming an elliptical opening at the side of the storage bag, which is convenient for the insertion action of the guide plate mechanism 12.

[0049] As a further solution in the present invention, the guide plate mechanism 12 includes a guide plate bracket 121, and a guide slide bar 122 is provided at the front end of the guide plate bracket 121, and a main guide member 123 is fixedly installed in the middle of the guide slide bar 122, and auxiliary guide members 124 are slidably installed at the two end positions of the guide slide bar 122, and the rear end of the guide plate bracket 121 is rotatably installed with a motor-driven bidirectional threaded screw 126, and the two auxiliary guide members 124 are respectively screwed to the two end positions of the bidirectional threaded screw 126. In the present invention, the main guide member 123 and the two auxiliary guide members 124 are initially gathered together. When the main guide member 123 and the two auxiliary guide members 124 are inserted into the gap between the plug-in plates at the edge of the storage bag, the two auxiliary guide members 124 move synchronously toward the two ends under the action of the bidirectional threaded screw 126 and the motor, thereby expanding the two ends of the gap between the plug-in plates and providing a guiding effect for the insertion of the hard plastic plate, thereby improving the convenience of the hard plastic plate insertion operation.

[0050] As a further solution in the present invention, the main guide member 123 and the two auxiliary guide members 124 are both composed of two guide plates with a V-shaped structure, and the guide plate located on the outside of the auxiliary guide member 124 is provided with an R-shaped constraint plate 125. In the present invention, when the auxiliary guide member 124 is inserted between the outer fabric and the inner fabric of the storage bag, the constraint plate 125 clamps the outer fabric of the storage bag under the action of elastic force. After the insertion action is completed, the constraint plate 125 applies an upward pulling force to the outer fabric of the storage bag when it moves upward, thereby flattening the two ends of the outer fabric of the storage bag upward, keeping the bag opening of the storage bag flush after the insertion action, and facilitating the clamping and fixing of the bag supporting mechanism 11.

[0051] When in use, two sets of plate inserting devices are installed at the periphery of the stand. The two sets of plate inserting devices respectively insert the side plates and end plates of the storage box. The storage bag is opened and fixed at the lower position of the bag-opening mechanism 11, keeping the four corners of the bag opening consistent with the four corners of the bag-opening mechanism 11. Each set of opening components is distributed to clamp and fix the side edges and end edges of the bag opening. The plate inserting device is provided with a corresponding plate storage mechanism 8 and a guide plate mechanism 12.

[0052] When inserting the side plate, the feeding cylinder 9 pushes the storage bag horizontally to the position below the guide plate mechanism 12 and enters the inserting plate station. The bag-stretching mechanism 11 then retracts the two opening components close to the inserting plate device, loosens the edge of the storage bag on the side to be inserted into the inserting plate, and the opening mechanism 13 approaches the outside of the storage bag. After that, the opening mechanism 13 and the suction head assembly 115 move to both sides synchronously, thereby separating the outer layer of fabric and the inner layer of fabric on the side of the storage bag. Subsequently, the electric push rod 10 drives the bag-stretching mechanism 11 to move upward, inserting the guide plate mechanism 12 into the inserting plate gap between the outer layer of fabric and the inner layer of fabric. The guide plate mechanism 12 then moves to both ends of the inserting plate gap to completely stretch the outer layer of fabric and the inner layer of fabric apart.

[0053] Afterwards, the insert plate driving mechanism 4 drives the push plate 6 and the correcting mechanism 2 to move synchronously. The push plate 6 pushes the hard plastic plate at the front end of the storage plate mechanism 8 downward, and the hard plastic plate is directly inserted between the outer layer of fabric and the inner layer of fabric from the middle of the guide plate mechanism 12. When the hard plastic plate is inserted into the bottom end of the storage bag, the upper layer of the correcting mechanism 2 contacts the bottom position of the storage bag, and the elastic force of the correcting mechanism 2 is used to provide positioning for the bottom ends of the hard plastic plate and give a signal that the hard plastic plate is inserted into the set position;

[0054] Afterwards, the inserting plate driving mechanism 4 drives the pushing plate 6 to move upward. After completing the inserting action on one side, the electric push rod 10 drives the bag-opening mechanism 11 to move downward. The guide plate mechanism 12 is separated from the gap between the outer layer fabric and the inner layer fabric inserting plate on the side of the storage bag. The bag-opening mechanism 11 then resets the two opening components close to the inserting plate device to fix the bag opening on the side of the storage bag inserted into the hard plastic plate.

[0055] Afterwards, the rotating motor 7 drives the bag-supporting mechanism 11 to rotate half a circle, repeating the above-mentioned plate insertion action, and performing the plate insertion operation on the other side of the storage bag. After the side plate insertion is completed, it is switched to another plate insertion device and enters the end plate insertion station. The end plate is inserted in the same steps, thereby realizing the continuous plate insertion action of the storage bag, shortening the production time of the storage box, and improving production efficiency.

[0056] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
