Description

Technical Field

[0001] The present invention relates to the field of carton creasing and forming devices, and specifically to a cardboard creasing device and its working method. Background Art

[0002] A creasing device is a device used to generate creases on the surface of cardboard to facilitate subsequent folding of the cardboard into a box-like structure. In the prior art, the cardboard creasing device generally forms the creases on the surface of the cardboard through upper and lower molds during use. However, after the creases are generated on the surface of the cardboard, since the cardboard with creases has a certain ability to swing and deform, it is difficult to collect the cardboard regularly through mechanical automation. Therefore, it is necessary to manually collect and sort the cardboard, which is too inconvenient. Summary of the Invention

[0003] The present invention provides a cardboard creasing device and its working method, which overcomes the deficiencies described in the background art.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] A cardboard creasing device includes a pushing member, a pressing mechanism, a receiving mechanism, and a movable bottom plate. The pushing member and the receiving mechanism are respectively arranged on both sides of the movable bottom plate, and the pressing mechanism is located directly above the movable bottom plate. A cardboard to be formed is placed on the surface of the movable bottom plate, so as to form a pressed mark on the surface of the cardboard through the pressing of the pressing mechanism and the movable bottom plate, and the formed cardboard is pushed into the receiving mechanism by the pushing member;

[0006] The pressing mechanism includes a pushing cylinder 1, a connecting plate 1, a connecting plate 2, and a crease forming knife. The crease forming knife is fixed to the lower side of the connecting plate 1 through the connecting plate 2, and the connecting plate 1 is installed on the output shaft of the pushing cylinder 1. A lifting and pressing forming plate and a spring 1 are arranged inside the movable bottom plate. The lifting and pressing forming plate is supported by the spring 1 and protrudes from the surface of the movable bottom plate. The cardboard to be formed is placed on the upper side of the lifting and pressing forming plate;

[0007] The pushing member includes a movable cover plate, a movable push plate, and a pushing cylinder 2. The movable cover plate covers the upper side of the movable push plate. Slide bars are respectively arranged on both sides of the movable push plate, and sliding grooves are respectively arranged at both inner ends of the movable cover plate. Both slide bars are respectively slidably arranged in the adjacent sliding grooves. An extension plate is arranged on one side of the movable push plate close to the pushing cylinder 2. Fixing plates are arranged on both the extension plate and the upper side of the movable cover plate. A spring 2 is arranged between the two fixing plates. A strip-shaped groove is arranged at the corresponding position between the movable cover plate and the extension plate. The extension plate is connected to the output shaft of the pushing cylinder 2 through the fixing plate arranged on its surface, so as to drive the movable push plate to push the movable cover plate to move through the pushing cylinder 2.

[0008] A preferred technical solution is that the storage mechanism includes a base, a collection bin and an iron collection box arranged on the base. One side of the collection bin facing the iron collection box is open, and a feeding port is arranged on the side of the collection bin facing the pressing mechanism. The feeding port is flush with the upper end surface of the movable bottom plate, and the thickness of the feeding port is higher than the height of the formed cardboard, so as to push the formed cardboard into the collection bin from the feeding port through the movable cover plate;

[0009] The iron collection box includes linear rails I respectively arranged on both sides of the base. Sliders are slidably arranged on the linear rails I. A long connecting plate is connected to the surface of the slider. The long connecting plate is adsorbed and abutted against the iron collection box through an adsorption magnet. When storing the formed cardboard, the iron collection box is pushed into the collection bin from the opening on the side of the collection bin, and the height of the iron collection box is lower than the height of the feeding port.

[0010] A preferred technical solution is that a pressing assembly is further arranged on the collection bin. The pressing assembly is driven to move through a driving mechanism. The pressing assembly includes a U-shaped plate, an electric push rod, a strip-shaped pressing bar and a cross-shaped bottom plate. Three electric push rods are sequentially installed on the lower side of the U-shaped plate from left to right. The strip-shaped pressing bar is arranged on the upper side of the cross-shaped bottom plate, and the strip-shaped pressing bar is driven to lift through the electric push rod located in the middle. The cross-shaped bottom plate is driven to lift through the other two electric push rods;

[0011] The driving mechanism includes a motor and a linear rail II. The U-shaped plate is slidably arranged on the linear rail II through a screw rod slider. A screw rod penetrating through the screw rod slider is installed on the output shaft of the motor. The screw rod is threadedly connected with the screw rod slider.

[0012] A preferred technical solution is that one side of the iron collection box away from the pressing mechanism is open. A stepped edge recessed inward is arranged at the lower part of the side of the collection bin close to the opening of the iron collection box. A channel for the cross-shaped bottom plate to move is formed between the stepped edge and the surface of the iron collection box;

[0013] The strip-shaped pressing bar is in a strip structure. An adjustment groove I is arranged at the corresponding position of the side of the collection bin close to the channel and opposite to the strip-shaped pressing bar. When the driving mechanism drives all the electric push rods to move the strip-shaped pressing bar and the cross-shaped bottom plate outward, the cross-shaped bottom plate moves outward through the channel, while the strip-shaped pressing bar moves outward through the adjustment groove I.

[0014] A preferred technical solution is that a lug is respectively arranged on both sides of the cross-shaped bottom plate. A strip-shaped pressing bar corresponding to the lug is arranged on the side of the adjustment groove II away from the iron collection box. The lug extends outside the collection bin through the strip-shaped pressing bar. The output shafts of the left and right electric push rods are respectively connected to the lugs on both sides of the cross-shaped bottom plate. When the electric push rod moves the cross-shaped bottom plate downward, the lugs arranged on the side surface of the cross-shaped bottom plate slide in the strip-shaped pressing bar.

[0015] In a preferred technical solution, a resistance portion protruding outward is provided above the feeding port. When the second pushing cylinder pushes the movable cover plate and the movable pushing plate to move towards the collection bin, the movable cover plate abuts against the resistance portion, and the movable pushing plate pushes the formed cardboard into the iron collection box in the collection bin through the movable pushing plate during the continuous extension of the output shaft of the second pushing cylinder;

[0016] The slider is flush with the side of the iron collection box close to the collection bin, and the long connecting plate is connected to the side of the iron collection box away from the collection bin. When the iron collection box is pushed into the collection bin, the slider moves accordingly.

[0017] A working method of a cardboard creasing device, which is applied to the described cardboard creasing device, and the working method includes the following steps:

[0018] S1: Place the cardboard to be formed on the surface of the movable bottom plate, and press the surface of the cardboard into creases through the pressing mechanism and the movable bottom plate;

[0019] S2: After pressing and forming, use the first spring to lift the lifting and pressing forming plate and the cardboard on its surface, and by pushing the movable pushing plate towards the storage mechanism, make the movable pushing plate move the movable cover plate forward by using the second spring, and cover the formed cardboard through the movable cover plate during the gradual movement, and use the movable pushing plate to push the formed cardboard towards the storage mechanism;

[0020] S3: During the continuous movement, first make the movable cover plate abut against the surface of the resistance portion due to the movable pushing plate, and under the continuous extension of the output shaft of the second pushing cylinder, make the movable pushing plate continue to move and push the formed cardboard into the iron collection box in the collection bin;

[0021] S4: Each time the formed cardboard is pushed into the iron collection box, the cross-shaped bottom plate moves down by the thickness of one formed cardboard, and presses all the formed cardboard placed in the iron collection box by pressing down the linear pressing strip until the cross-shaped bottom plate moves to the bottom of the iron collection box, and then use the driving mechanism to push the linear pressing strip and the cross-shaped bottom plate in the direction away from the pressing mechanism and withdraw them outside the collection bin.

[0022] Compared with the prior art, this technical solution has the following advantages:

[0023] Through the cooperation between the pushing member and the storage mechanism, the present invention realizes the automatic collection of cardboard. 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, which is convenient for storing and taking out the cardboard. In addition, through the precise cooperation between the pressing mechanism and the movable bottom plate, the accuracy and consistency of the cardboard creases are ensured, further improving the forming quality of the cardboard.

[0024] To facilitate the collection of the iron collection box, the iron collection box in the present invention includes wire rails I respectively arranged on both sides of the base. A slider is slidably arranged on the wire rail I, and a long connecting plate is connected to the surface of the slider. The long connecting plate is adsorbed and abutted against the iron collection box through an adsorption magnet. When storing the formed cardboard, the iron collection box is pushed into the collection bin from the opening on the side of the collection bin, and the height of the iron collection box is lower than the height of the feeding port. After the cardboard is formed under the action of the pressing mechanism, the movable push plate in the pushing member moves forward under the drive of the pushing cylinder II, and the formed cardboard is pushed from the movable bottom plate to the feeding port of the collection bin. Since the feeding port is flush with the upper end surface of the movable bottom plate and has sufficient thickness, the cardboard can smoothly enter the collection bin and finally fall into the iron collection box. Through the structural design of the wire rail I, the slider and the adsorption magnet, the stability and easy replacement of the iron collection box in the collection bin are ensured.

[0042] As Figures 1 to 7 shown, in the present invention, a cardboard creasing device is proposed, which includes a pushing member 1, a pressing mechanism 2, a storage mechanism 3 and a movable bottom plate 4. The pushing member 1 and the storage mechanism 3 are respectively arranged on both sides of the movable bottom plate 4, the pressing mechanism 2 is located directly above the movable bottom plate 4, and a cardboard to be formed is placed on the surface of the movable bottom plate 4, so as to press and form the surface crease of the cardboard through the pressing mechanism 2 and the movable bottom plate 4, and push the formed cardboard into the storage mechanism 3 through the pushing member 1;

[0043] The pressing mechanism 2 includes a first pushing cylinder 21, a first connecting plate 22, a second connecting plate 23 and a crease forming knife 24. The crease forming knife 24 is fixed to the lower side of the first connecting plate 22 through the second connecting plate 23, the first connecting plate 22 is installed on the output shaft of the first pushing cylinder 21, and a lifting and pressing forming plate 41 and a first spring 42 are arranged in the movable bottom plate 4. The lifting and pressing forming plate 41 is supported by the first spring 42, and the lifting and pressing forming plate 41 protrudes from the surface of the movable bottom plate 4. A cardboard to be formed is placed on the upper side of the lifting and pressing forming plate 41;

[0044] The pushing member 1 includes a movable cover plate 11, a movable push plate 12, and a second pushing cylinder 13. The movable cover plate 11 is disposed 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, and sliding grooves 111 are respectively arranged on both sides of the inner end of the movable cover plate 11. Both slide bars 122 are respectively slidably disposed in the adjacent sliding grooves 111. An extension plate 121 is arranged on one side of the movable push plate 12 close to the second pushing cylinder 13. Fixed plates 14 are arranged on both the extension plate 121 and the upper side of the movable cover plate 11. A second spring 15 is arranged between the two fixed plates 14. A strip-shaped groove is arranged at the corresponding position between the movable cover plate 11 and the extension plate 121. The extension plate 121 is connected to the output shaft of the second pushing cylinder 13 through the fixed plate 14 arranged on its surface, so as to drive the movable push plate 12 to push the movable cover plate 11 to move through the second pushing cylinder 13;

[0045] The pressing mechanism 2 is a key component for forming the crease of the cardboard. It is mainly driven by the first pushing cylinder 21. Through the first connecting plate 22 and the second connecting plate 23, the crease forming knife 24 is driven to perform a downward pressing action. When the cardboard to be formed is placed on the movable bottom plate 4, the first pushing cylinder 21 is started, driving the crease forming knife 24 to accurately press down to the surface of the cardboard, and acting 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 the built-in lifting and pressing forming plate 41 and the first spring 42. During the pressing process, the lifting and pressing forming plate 41 presses down together with the cardboard. When the pressing is completed, the first spring 42 quickly jacks up the lifting and pressing forming plate 41 and the cardboard by using its elastic potential energy, making the cardboard return to a flat state, facilitating subsequent pushing and collecting operations. This design effectively improves the pressing efficiency and forming quality of the cardboard;

[0046] The pushing member 1 is responsible for pushing the formed cardboard from the movable bottom plate 4 into the receiving mechanism 3. When the cardboard pressing is completed, the second pushing cylinder 13 is started, and the movable push plate 12 is pushed forward through the extension plate 121. During the movement of the movable push plate 12, the slide bars 122 on both sides thereof slide in the sliding grooves 111 inside the movable cover plate 11 to maintain a stable movement track. At the same time, the movable cover plate 11 follows the movable push plate 12 to move forward under the action of the second spring 15, covering and protecting the formed cardboard. Finally, the movable push plate 12 pushes the formed cardboard into the feeding port 322 of the receiving mechanism 3 to complete the collection operation of the cardboard.

[0047] In view of the problem that the existing cardboard creasing device mentioned in the background art is difficult to automatically collect the cardboard after it is formed, the present invention realizes the automatic collection of the cardboard by ingeniously designing the cooperation 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, through the precise cooperation between the pressing mechanism 2 and the movable bottom plate 4, the accuracy and consistency of the cardboard crease are ensured, further improving the forming quality of the cardboard.

[0048] Furthermore, the storage mechanism 3 includes a base 31, a collection bin 32 and an iron collection box 33 arranged on the base 31. One side of the collection bin 32 facing the iron collection box 33 is open, and a feeding port 322 is arranged on the side of the collection bin 32 facing the pressing mechanism 2. The feeding port 322 is flush with the upper end surface of the movable bottom plate 4, and the thickness of the feeding port 322 is higher than the height of the formed cardboard, so as to push the formed cardboard into the collection bin 32 through the movable cover plate 11; one side of the collection bin 32 facing the iron collection box 33 is open, which is convenient for the pushing and taking out of the iron collection box 33. At the same time, a feeding port 322 is arranged on the side of the collection bin 32 facing the pressing mechanism 2. The feeding 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 feeding port 322 is designed to be higher than the height of the formed cardboard. This design takes into account the possible slight deformation or offset of the cardboard during the pushing process, ensuring that the cardboard can smoothly enter the collection bin 32 without being blocked.

[0049] Moreover, in order to facilitate the collection of the iron collection box 33, the iron collection box 33 in the present invention includes linear rails 311 respectively arranged on both sides of the base 31. A slider 312 is slidably arranged on the linear rails 311. 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 magnet 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 feeding port 322. After 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 two 13, and pushes the formed cardboard from the movable bottom plate 4 to the feeding port 322 of the collection bin 32. Since the feeding 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 structural design of the iron collection box 33 through the linear rails 311, the sliders 312 and the adsorption magnets 314 ensures its stability and easy replacement in the collection bin 32.

[0050] Further, a pressing component 34 is also provided on the collection bin 32. The pressing component 34 is driven to move by a driving mechanism 35. The pressing component 34 includes a U-shaped plate 341, an electric push rod 342, a linear pressing strip 343, and a grid-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. The linear pressing strip 343 is arranged on the upper side of the grid-shaped bottom plate 344, and the linear pressing strip 343 is driven to lift by the electric push rod 342 located in the middle. The grid-shaped bottom plate 344 is driven to lift by the other two electric push rods 342;

[0051] The driving mechanism 35 includes a motor 351 and a second linear guide 352. The U-shaped plate 341 is slidably arranged on the second linear guide 352 through a screw rod slider 3411. A screw rod 3511 passing through the screw rod slider 3411 is installed on the output shaft of the motor 351. The screw rod 3511 is threadedly connected to the screw rod slider 3411;

[0052] The pressing component 34 realizes multi-directional pressing of the cardboard through the three electric push rods 342 below the U-shaped plate 341. The electric push rod 342 in the middle drives the linear pressing strip 343 to lift, performing longitudinal pressing on the cardboard to ensure tight fitting in the stacking direction. The other two electric push rods 342 drive the grid-shaped bottom plate 344 to lift. The grid-shaped bottom plate 344 cooperates with the linear pressing strip 343 to realize lateral pressing of the cardboard, preventing the cardboard from shifting or scattering during the stacking process.

[0053] Moreover, the stroke and speed of the electric push rod 342 can be adjusted according to actual needs to adapt to cardboard of different thicknesses and materials. This flexible adjustment ability 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 linear pressing strip 343 and the grid-shaped bottom plate 344 to lift, performing 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 best 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.

[0054] Further, one side of the iron collecting box 33 away from the pressing mechanism 2 is open. A stepped edge recessed inward is provided at the lower part of one side of the collecting bin 32 close to the opening of the iron collecting box 33. A channel for the movement of the cross-shaped bottom plate 344 is formed between the stepped edge and the surface of the iron collecting box 33. The collecting bin 32 is the main area for cardboard collection. A stepped edge recessed inward is provided at the lower part of one side of the collecting bin 32 close to the opening of the iron collecting box 33. 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 movement of the cross-shaped bottom plate 344 in the pressing assembly 34 between its surface and the surface of the iron collecting box 33. One side of the iron collecting box 33 away from the pressing mechanism 2 is open, which is convenient for the collection and removal of cardboard. At the same time, its surface cooperates with the stepped edge of the collecting bin 32 to ensure that the cross-shaped bottom plate 344 will not be hindered during the movement;

[0055] The linear pressing strip 343 has a strip structure. An adjustment groove 321 is provided at the corresponding position of one side of the collecting bin 32 close to the channel. When the driving mechanism 35 drives all the electric push rods 342 to move the linear pressing strip 343 and the cross-shaped bottom plate 344 outward, the cross-shaped bottom plate 344 moves outward through the channel, while the linear pressing strip 343 moves outward through the adjustment groove 321;

[0056] When a batch of cardboard is collected, the driving mechanism 35 is started to drive all the electric push rods 342 to move outward. At this time, the cross-shaped bottom plate 344 smoothly moves outward through the channel between the collecting bin 32 and the iron collecting box 33, while the linear pressing strip 343 performs a horizontal adjustment movement through the adjustment groove 321 provided on the collecting bin 32. This design ensures that the pressing assembly 34 can maintain a stable posture during the outward movement and avoid interference with the collecting bin 32 or the iron collecting box 33.

[0057] The working process is as follows:

[0058] After the cardboard is formed under the action of the pressing mechanism 2, it is pushed into the collecting bin 32. The pressing assembly 34 performs multi-directional pressing on the cardboard under the drive of the driving mechanism 35 to ensure that the cardboard is stacked neatly. After a batch of cardboard is collected, the driving mechanism 35 is started to drive the pressing assembly 34 to smoothly move out of the collecting bin 32 through the channel between the collecting bin 32 and the iron collecting box 33 and the adjustment groove 321 for the collection of the next batch of cardboard. The present invention innovatively solves the problems of possible scattering of the cardboard during the cardboard collection process and the unsmooth movement out of the pressing assembly by introducing the design of the stepped edge and the channel, the setting of the adjustment groove 321 and the precise control mechanism of the driving mechanism 35.

[0059] Moreover, there is a lug on each side of the cross-shaped bottom plate 344. On the side of the adjustment groove 2 323 away from the iron collection box 33, there is a corresponding cross-shaped pressing strip 343 for the lug. The lug extends outside the collection bin 32 through the cross-shaped pressing strip 343. 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 cross-shaped bottom plate 344. When the electric push rod 342 moves the cross-shaped bottom plate 344 downward, the lugs arranged on the side surface of the cross-shaped bottom plate 344 slide within the cross-shaped pressing strip 343.

[0060] Furthermore, there is a protruding resistance portion 3221 on the upper side of the feeding port 322. When the pushing cylinder 2 13 pushes the movable cover plate 11 and the movable push plate 12 to move towards the collection bin 32, the movable cover plate 11 abuts against the resistance portion 3221, and enables the movable push plate 12 to push the formed cardboard into the iron collection box 33 within the collection bin 32 during the continuous extension of the output shaft of the pushing cylinder 2 13. When the pushing cylinder 2 13 pushes the movable cover plate 11 and the movable push plate 12 to move towards the collection bin 32, the movable cover plate 11 first abuts against the resistance portion 3221. Subsequently, during the continuous extension of the output shaft of the pushing cylinder 2 13, the movable push plate 12 pushes the formed cardboard into the iron collection box 33 within the collection bin 32. This cooperation mechanism ensures the accuracy and stability of cardboard feeding.

[0061] 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.

[0062] 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 feeding port 322. At this time, the movable cover plate 11 abuts against the resistance portion 3221 to ensure that the cardboard does not scatter. Then, the pushing cylinder 2 13 pushes 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 cross-shaped pressing strip 343 to descend to press the cardboard. After the pressing is completed, the electric push rod 342 drives the cross-shaped pressing strip 343 to rise. After a whole batch of cardboard is collected, the cross-shaped pressing strip 343 and the cross-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.

[0063] A working method of a cardboard creasing device is applied to a cardboard creasing device. The working method includes the following steps:

[0064] S1: Place the cardboard to be formed on the surface of the movable bottom plate 4, and press and form the surface creases of the cardboard through the pressing mechanism 2 and the movable bottom plate 4.

[0065] S2: After press forming, use spring 1 - 42 to lift the lift press forming plate 41 and the cardboard on its surface, and push the movable push plate 12 towards the storage mechanism 3 through the push cylinder 2 - 13, so that the movable push plate 12 moves the movable cover plate 11 forward by using spring 2 - 15, and covers the formed cardboard through the movable cover plate 11 during the gradual movement, and pushes the formed cardboard towards the storage mechanism 3 by using the movable push plate 12;

[0066] S3: During the continuous movement, first make the movable cover plate 11 abut against the surface of the resistance part 3221 due to the movable push plate 12, and under the continuous extension of the output shaft of the push cylinder 2 - 13, make the movable push plate 12 continuously move and push the formed cardboard into the iron collection box 33 in the collection bin 32;
