[0010] A working method of a cardboard crease device is applied to the cardboard crease device, and the working method comprises the following steps: S1: placing the paperboard to be formed on the surface of the movable bottom plate, and pressing the paperboard with the movable bottom plate through a pressing mechanism to form creases on the surface of the paperboard; S2: After the pressing and forming, the pressing and forming plate and the paperboard on its surface are lifted and lowered by using the spring 1, and the movable push plate is pushed toward the storage mechanism, so that the movable push plate moves the movable cover plate forward by using the spring 2, and the formed paperboard is covered by the movable cover plate during the gradual movement, and the formed paperboard is pushed toward the storage mechanism by using the movable push plate; S3: During the continuous movement, the movable cover plate is first pressed against the surface of the resistance part by the movable push plate, and under the continuous extension of the second output shaft of the push cylinder, the movable push plate is continuously moved and pushes the formed cardboard into the iron collection box in the collection bin; S4: Each time the formed cardboard is pushed into the iron collection box, the field-shaped bottom plate moves down by the thickness of a formed cardboard, and squeezes all the formed cardboards placed in the iron collection box by pressing down the I-shaped pressure strip until the field-shaped bottom plate moves to the bottom of the iron collection box, and then the I-shaped pressure strip and the field-shaped bottom plate are pushed away from the pressing mechanism through the driving mechanism and withdrawn to the outside of the collection bin.

[0011] Compared with the prior art, this technical solution has the following advantages: The present invention realizes the automatic collection of cardboard through the cooperation relationship between the pushing member and the storage mechanism. Specifically, the pushing member can accurately push the formed cardboard into the iron collection box in the storage mechanism without manual intervention. At the same time, the collection bin and the iron collection box in the storage mechanism are reasonably designed to facilitate the storage and removal of cardboard.

DETAILED DESCRIPTION

[0027] like Figures 1 to 7 As shown, the present invention proposes a paperboard crease device, comprising a pushing member 1, a pressing mechanism 2, a storage mechanism 3 and a movable bottom plate 4, wherein the pushing member 1 and the storage mechanism 3 are respectively arranged on both sides of the movable bottom plate 4, and the pressing mechanism 2 is located directly above the movable bottom plate 4, and paperboard to be formed is placed on the surface of the movable bottom plate 4, so that the pressing mechanism 2 and the movable bottom plate 4 are pressed to form an indentation on the surface of the formed paperboard, and the formed paperboard is pushed into the storage mechanism 3 by the pushing member 1; The pressing mechanism 2 includes a pushing cylinder 1 21, a connecting plate 1 22, a connecting plate 23 and a crease forming knife 24. The crease forming knife 24 is fixed to the lower side of the connecting plate 1 22 through the connecting plate 23. The connecting plate 1 22 is installed on the output shaft of the pushing cylinder 1 21. A lifting and lowering pressure synthesis plate 41 and a spring 1 42 are arranged in the movable bottom plate 4. The lifting and lowering pressure synthesis plate 41 is supported by the spring 1 42, and the lifting and lowering pressure synthesis plate 41 protrudes from the surface of the movable bottom plate 4. The paperboard to be formed is placed on the upper side of the lifting and lowering pressure synthesis plate 41. The pushing member 1 includes a movable cover plate 11, a movable push plate 12 and a push cylinder 2 13. The movable cover plate 11 is covered on the upper side of the movable push plate 12. Slide bars 122 are respectively arranged on both sides of the movable push plate 12. Slide grooves 111 are respectively arranged on both sides of the inner end of the movable cover plate 11. The two slide bars 122 are respectively slid in the slide grooves 111 adjacent thereto. An extension plate 121 is arranged on the side of the movable push plate 12 close to the push cylinder 2 13. A fixing plate 14 is arranged on the extension plate 121 and the upper side of the movable cover plate 11. A spring 2 15 is arranged between the two fixing plates 14. A strip groove is arranged at the corresponding position of the movable cover plate 11 and the extension plate 121. The extension plate 121 is connected to the output shaft of the push cylinder 2 13 through the fixing plate 14 arranged on its surface, so as to drive the movable push plate 12 to push the movable cover plate 11 to move by the push cylinder 2 13; The pressing mechanism 2 is a key component for forming the crease of the cardboard. It is mainly driven by the push cylinder 1 21, and drives the crease forming knife 24 to press down through the connecting plate 1 22 and the connecting plate 2 23. When the cardboard to be formed is placed on the movable bottom plate 4, the push cylinder 1 21 is started to drive the crease forming knife 24 to accurately press down to the surface of the cardboard, and work together with the movable bottom plate 4 to form a clear crease. This process ensures the accuracy and consistency of the cardboard crease, laying a foundation for subsequent forming. The movable bottom plate 4 not only serves as a bearing platform for the cardboard, but also realizes the stable pressing and lifting of the cardboard through its built-in lifting and pressing synthesis plate 41 and spring 1 42. During the pressing process, the lifting and pressing synthesis plate 41 is pressed down together with the cardboard. When the pressing is completed, the spring 1 42 uses its elastic potential energy to quickly lift the lifting and pressing synthesis plate 41 and the cardboard, so that the cardboard is restored to a flat state, which is convenient for subsequent pushing and collecting operations. This design effectively improves the pressing efficiency and forming quality of the cardboard. The pushing member 1 is responsible for pushing the formed cardboard from the movable bottom plate 4 into the storage mechanism 3. When the cardboard is pressed, the push cylinder 2 13 is started, and the movable push plate 12 is pushed forward by the extension plate 121. During the movement, the movable push plate 12 uses the slide bars 122 on both sides to slide in the slide groove 111 on the inner side of the movable cover plate 11 to maintain a stable moving trajectory. At the same time, the movable cover plate 11 moves forward with the movable push plate 12 under the action of the spring 2 15 to cover and protect the formed cardboard. Finally, the movable push plate 12 pushes the formed cardboard into the delivery port 322 of the storage mechanism 3 to complete the cardboard collection operation.

[0028] In view of the problem mentioned in the background technology that the existing cardboard crease device is difficult to automatically collect the cardboard after it is formed, the present invention realizes the automatic collection of the cardboard by cleverly designing the matching relationship between the pushing member 1 and the storage mechanism 3. Specifically, the pushing member 1 can accurately push the formed cardboard into the iron collection box 33 in the storage mechanism 3 without manual intervention. At the same time, the collection bin 32 and the iron collection box 33 in the storage mechanism 3 are reasonably designed to facilitate the storage and removal of the cardboard. In addition, the precise matching of the pressing mechanism 2 and the movable bottom plate 4 ensures the accuracy and consistency of the cardboard crease, further improving the forming quality of the cardboard.

[0029] Furthermore, the storage mechanism 3 includes a base 31 and a collection bin 32 and an iron collection box 33 arranged on the base 31. The collection bin 32 is open on the side facing the iron collection box 33, and a delivery port 322 is provided on the side facing the pressing mechanism 2. The delivery port 322 is flush with the upper end surface of the movable bottom plate 4, and the thickness of the delivery port 322 is higher than the height of the formed cardboard, so that the formed cardboard can be pushed from the delivery port 322 into the collection bin 32 through the movable cover plate 11; the collection bin 32 is open on the side facing the iron collection box 33, which is convenient for pushing in and out the iron collection box 33. At the same time, a delivery port 322 is provided on the side facing the pressing mechanism 2, and the delivery port 322 is flush with the upper end surface of the movable bottom plate 4, ensuring that the formed cardboard can be smoothly pushed from the movable bottom plate 4 into the collection bin 32. The thickness of the delivery port 322 is designed to be higher than the height of the formed cardboard. This design takes into account the slight deformation or deviation that may occur to the cardboard during the pushing process, ensuring that the cardboard can smoothly enter the collection bin 32 without being hindered.

[0030] Furthermore, in order to facilitate the collection of the iron collection box 33, the iron collection box 33 of the present invention includes a linear rail 1 311 provided on both sides of the base 31, a slider 312 is slidably provided on the linear rail 1 311, and a long connecting plate 313 is connected to the surface of the slider 312. The long connecting plate 313 is adsorbed and abutted against the iron collection box 33 through an adsorption magnetic block 314. When storing the formed cardboard, the iron collection box 33 is pushed into the collection bin 32 from the opening on the side of the collection bin 32, and the height of the iron collection box 33 is lower than the height of the delivery port 322. When the cardboard is formed under the action of the pressing mechanism 2, the movable push plate 12 in the pushing member 1 moves forward under the drive of the pushing cylinder 2 13, and pushes the formed cardboard from the movable bottom plate 4 to the delivery port 322 of the collection bin 32. Since the delivery port 322 is flush with the upper end surface of the movable bottom plate 4 and has sufficient thickness, the cardboard can smoothly enter the collection bin 32 and finally fall into the iron collection box 33. The iron collecting box 33 is designed with a linear rail 311, a slider 312 and an adsorption magnetic block 314 to ensure its stability and easy replacement in the collecting bin 32.

[0031] Furthermore, a pressing assembly 34 is also provided on the collection bin 32, and the pressing assembly 34 is driven to move by a driving mechanism 35. The pressing assembly 34 includes a U-shaped plate 341, an electric push rod 342, a straight-line pressure strip 343 and a field-shaped bottom plate 344. Three electric push rods 342 are sequentially installed on the lower side of the U-shaped plate 341 from left to right, and the straight-line pressure strip 343 is arranged on the upper side of the field-shaped bottom plate 344, and the straight-line pressure strip 343 is driven to rise and fall by the electric push rod 342 located in the middle side, and the field-shaped bottom plate 344 is driven to rise and fall by the other two electric push rods 342; The driving mechanism 35 includes a motor 351 and a second linear track 352. The U-shaped plate 341 is slidably arranged on the second linear track 352 via a screw slider 3411. A screw 3511 penetrating the screw slider 3411 is installed on the output shaft of the motor 351. The screw 3511 is threadedly connected to the screw slider 3411. The pressing assembly 34 realizes multi-directional pressing of the cardboard through the three electric push rods 342 under the U-shaped plate 341. The electric push rod 342 on the middle side drives the straight-line pressure strip 343 to rise and fall, and presses the cardboard longitudinally to ensure that the cardboard fits tightly in the stacking direction. The other two electric push rods 342 drive the field-shaped bottom plate 344 to rise and fall, and the field-shaped bottom plate 344 cooperates with the straight-line pressure strip 343 to realize the horizontal pressing of the cardboard to prevent the cardboard from being offset or scattered during the stacking process.

[0032] In addition, the stroke and speed of the electric push rod 342 can be adjusted according to actual needs to adapt to cardboards of different thicknesses and materials. This flexible adjustment capability enables the pressing component 34 to be applicable to a wider range of production scenarios, improving the versatility and practicality of the equipment. After the cardboard is formed and pushed to the collection bin 32, the driving mechanism 35 is first started to drive the pressing component 34 to move above the formed cardboard. Then, the electric push rod 342 starts to work, driving the I-shaped pressure strip 343 and the field-shaped bottom plate 344 to rise and fall, and perform multi-directional pressing on the cardboard. During the pressing process, the stroke and speed of the electric push rod 342 are automatically adjusted according to the thickness and material of the cardboard to ensure the optimization of the pressing effect. After the pressing operation of the pressing component 34, the cardboard is stacked more neatly and tightly in the collection bin 32. This stacking method not only improves the storage efficiency of the cardboard, but also reduces the risk of damage to the cardboard during transportation, providing convenience for subsequent packaging and transportation work.

[0033] Furthermore, the side of the iron collecting box 33 away from the pressing mechanism 2 is in an open shape, and the lower part of the side of the collection bin 32 close to the opening of the iron collecting box 33 is provided with an inwardly recessed step edge, and a channel for the field-shaped bottom plate 344 to move is formed between the step edge and the surface of the iron collecting box 33. The collection bin 32 serves as the main area for collecting cardboard, and the lower part of the side close to the opening of the iron collecting box 33 is provided with an inwardly recessed step edge. This design not only provides a stable support for the installation of the iron collecting box 33, but more importantly, it forms a channel for the field-shaped bottom plate 344 in the pressing assembly 34 to move between it and the surface of the iron collecting box 33. The side of the iron collecting box 33 away from the pressing mechanism 2 is in an open shape, which is convenient for collecting and taking out cardboard. At the same time, its surface cooperates with the step edge of the collection bin 32 to ensure that the field-shaped bottom plate 344 will not be obstructed during the movement. The straight-line pressure strip 343 is in a strip-shaped structure. An adjusting groove 1 321 is provided at a side of the collection bin 32 close to the passage and corresponding to the straight-line pressure strip 343. When the driving mechanism 35 drives all the electric push rods 342 to move the straight-line pressure strip 343 and the field-shaped bottom plate 344 outward, the field-shaped bottom plate 344 moves outward through the passage, and the straight-line pressure strip 343 moves outward through the adjusting groove 1 321. When a batch of cardboards is collected, the driving mechanism 35 is started to drive all the electric push rods 342 to move outward. At this time, the field-shaped bottom plate 344 moves outward smoothly through the channel between the collection bin 32 and the iron collection box 33, and the straight-shaped pressure strip 343 is adjusted and moved horizontally through the adjustment slot 1 321 set on the collection bin 32. This design ensures that the pressing assembly 34 can maintain a stable posture during the removal process to avoid interference with the collection bin 32 or the iron collection box 33.

[0034] The workflow is as follows: After the cardboard is formed under the action of the pressing mechanism 2, it is pushed into the collection bin 32. The pressing assembly 34 is driven by the driving mechanism 35 to press the cardboard in multiple directions to ensure that the cardboard is neatly stacked. After a batch of cardboards are collected, the driving mechanism 35 is started to drive the pressing assembly 34 to smoothly move out of the collection bin 32 through the channel and the adjustment groove 321 between the collection bin 32 and the iron collection box 33, so as to collect the next batch of cardboards. The present invention innovatively solves the problem of the cardboard crease device being scattered during the cardboard collection process and the problem of the pressing assembly not being smoothly moved out by introducing the design of the step edge and the channel, the setting of the adjustment groove 321 and the precise control mechanism of the driving mechanism 35.

[0035] In addition, a lug is provided on each side of the field-shaped bottom plate 344, and a straight-line pressure strip 343 corresponding to the lug is provided on the side of the adjustment slot 2 323 away from the iron collecting box 33. The lug extends to the outside of the collection bin 32 through the straight-line pressure strip 343, and the output shafts of the electric push rods 342 on the left and right sides are respectively connected to the lugs on both sides of the field-shaped bottom plate 344. When the electric push rods 342 move the field-shaped bottom plate 344 downward, the lugs provided on the side of the field-shaped bottom plate 344 slide in the straight-line pressure strip 343.

[0036] Furthermore, an outwardly protruding resistance portion 3221 is provided on the upper side of the delivery port 322. When the push cylinder 2 13 pushes the movable cover plate 11 and the movable push plate 12 to move toward the collection bin 32, the movable cover plate 11 abuts against the resistance portion 3221, and the movable push plate 12 pushes the molded cardboard into the iron collection box 33 in the collection bin 32 through the movable push plate 12 in the process of pushing the cylinder 2 13 to continuously extend the output shaft. When the push cylinder 2 13 pushes the movable cover plate 11 and the movable push plate 12 to move toward the collection bin 32, the movable cover plate 11 first abuts against the resistance portion 3221, and then, in the process of pushing the cylinder 2 13 to continuously extend the output shaft, the movable push plate 12 pushes the molded cardboard into the iron collection box 33 in the collection bin 32. This cooperative mechanism ensures the accuracy and stability of cardboard delivery. The slider 312 is flush with the side of the iron collection box 33 close to the collection bin 32, and the long connecting plate 313 is connected to the side of the iron collection box 33 away from the collection bin 32. When the iron collection box 33 is pushed into the collection bin 32, the slider 312 moves accordingly. Therefore, it can be known that after the cardboard is formed under the action of the pressing mechanism 2, it enters the collection bin 32 through the delivery port 322. At this time, the movable cover plate 11 is against the resistance part 3221 to ensure that the cardboard will not scatter. Then, the cylinder 2 13 is pushed to push the movable push plate 12 to push the formed cardboard into the iron collection box 33. After each cardboard is collected, the electric push rod 342 will drive the I-shaped pressure strip 343 to descend to press the cardboard. After the pressing is completed, the electric push rod 342 drives the I-shaped pressure strip 343 to rise. After a complete batch of cardboards are collected, the I-shaped pressure strip 343 and the field-shaped bottom plate 344 are moved out of the collection bin 32. Finally, the iron collection box 33 can be taken out of the collection bin 32 through the slider 312 and the long connecting plate 313 for subsequent processing of the cardboard.
