Description

Technical Field

[0001] The invention relates to paper box inner support assembling equipment. Background Art

[0002] Paper boxes (such as drawer boxes, book-shaped boxes, square tube boxes, etc.) can be used for packaging, such as wine box packaging, etc., and an inner tray needs to be placed in the formed paper box to hold the items placed inside. The inner tray has a concave cavity that matches the items so that the items can be placed stably. The inner tray can be made of paper or plastic. Among them, the inner tray adopts a finished product structure that has been formed, and the inner tray can be conveniently taken out and placed in the paper box for assembly. The assembly method can be manual or robotic. However, for some types of inner trays that require additional forming operations, the inner tray needs to be manually formed (such as folding, crimping or flanging forming operations) and then manually loaded into the paper box for assembly. Manual forming efficiency is low and processing costs are high. In addition, the structure of the inner tray formed manually is not stable enough and is easy to deform before assembly is completed, making it difficult to assemble smoothly. Summary of the Invention

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the implementation of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] Referring to the accompanying drawings, in an embodiment of the present embodiment, a carton inner tray assembly machine includes a carton conveying mechanism 10 and an inner tray blank conveying mechanism 30. The carton conveying mechanism 10 is used to cooperate in conveying cartons to be assembled. The carton conveying mechanism 10 can even be connected to a carton production line. The carton conveying mechanism 10 has an inner tray boxing station 1, at which the inner tray is loaded into the carton to complete the assembly; the inner tray blank conveying mechanism 30 is used to cooperate in conveying the inner tray to be assembled, and the inner tray blank conveying mechanism 30 has a blank positioning station 3 (i.e., the inner tray blank positioning station). At the blank positioning station 3, the inner tray blank is ready to be placed and wait to be removed for forming. There is an inner tray boxing station 1 connected to the blank positioning station 3. The support forming station 2 cooperates with the inner support forming production at the inner support forming station 2, and the station structure layout is reasonable, which makes the operation relatively efficient and the structure relatively more compact; wherein, the blank positioning station 3 and the inner support forming station 2 are connected with the blank station transfer device 5, and the blank station transfer device 5 cooperates to transfer the inner support blank in place at the blank positioning station 3 to the inner support forming station 2 for cooperation in subsequent forming; wherein, the inner support forming station 2 and the inner support cartoning station 1 are connected with the inner support finished product inter-station transfer into box assembly device 4, and the inner support finished product inter-station transfer into box assembly device 4 cooperates to transfer the inner support formed at the inner support forming station 2 to the inner support cartoning station 1 for cooperation in paper box assembly.

[0040] Its working principle is as follows: the inner tray blank is transported to the blank positioning station 3 by the inner tray blank conveying mechanism 30, the paper box is transported to the inner tray cartoning station 1 by the paper box conveying mechanism 10, and the inner tray blank is transferred from the blank positioning station 3 to the inner tray forming station 2 by the blank station transfer device 5. After the inner tray blank is formed at the inner tray forming station 2, it is transferred into the box assembly device 4 between the inner tray finished product stations and transferred to the inner tray cartoning station 1 to be loaded into the waiting paper box to complete the assembly of the paper box and the inner tray.

[0041] In the paper box inner tray assembly machine, relying on the paper box conveying mechanism 10 and the inner tray blank conveying mechanism 30, a new workstation structure sequence layout is configured, providing an inner tray forming station 2 for the inner tray blank to be formed at this station, not only the conveying efficiency is high, but also the unformed inner tray can be directly transferred and output after the forming operation is completed at the inner tray forming station 2, and the formed inner tray can be directly transferred to participate in the subsequent assembly process (inner tray is loaded into paper box assembly), thereby improving the efficiency of the entire assembly process.

[0042] The following optimization or further explanation may be performed based on the above embodiments.

[0043] For example, the carton conveying mechanism 10 also has a carton gluing station 14 for cooperating with the gluing position of the inner support of the carton to apply glue. The carton gluing station 14 is located in the front position of the inner support box loading station 1, that is, the inner support and the carton will be further glued together to make it more secure when assembled, and the carton gluing station 14 is directly configured in the carton conveying mechanism 10. At the carton gluing station 14, the gluing position of the inner support of the carton (usually the bottom area of ​​the carton) is glued in advance before assembly, so that the subsequent assembly will be more secure.

[0044] After further optimization, the carton gluing station 14 is equipped with a carton gluing device 15, which includes a glue gun 151 for gluing the carton downward; the glue gun 151 is located above the carton conveying path of the carton conveying mechanism 10; the glue gun 151 is arranged to move horizontally and / or vertically, that is, the glue gun 151 can move horizontally and / or vertically, with a higher degree of freedom, and can meet the gluing needs of different positions and areas of the bottom of the box. In the figure, the lateral movement setting can adopt the following structure, the lateral movement drive motor 152 drives the gear 153, the gear 153 is connected to (drives) the rack 154, the rack 154 is connected to the lateral guide rail 155, the lateral guide rail 155 is connected to the lateral sliding support seat 156 (so that the lateral guide rail 155 slides horizontally thereon), and the lateral sliding support seat 156 is set on the longitudinal slide 159, and the longitudinal slide 159 is driven by the longitudinal drive motor 150 to move on the longitudinal guide rail 157, for example, the longitudinal drive motor 150 is connected to the lateral sliding support seat 156 through the screw rod and nut structure 158 to move; wherein the glue gun 151 can be installed on the rack 154.

[0045] For another example, the carton conveying mechanism 10 includes a carton conveyor belt 11, and the inner support carton loading station 1 of the carton conveying mechanism 10 is equipped with a first carton positioning device 12, and the carton gluing station 14 of the carton conveying mechanism 10 is equipped with a second carton positioning device 13. The corresponding carton positioning devices can limit the position of the carton to the corresponding station on the carton conveyor belt 11, so that the inner support carton loading, carton gluing and other operations are more stable and more precise.

[0046] For example, the first paper box positioning device 12 includes a first left clamping plate 121 and a first right clamping plate 122 that can cooperate with each other in opening and closing. The first left clamping plate 121 and the first right clamping plate 122 are separated left and right so that the paper box can be normally conveyed by the paper box conveying mechanism 10, and the first left clamping plate 121 and the first right clamping plate 122 are closed left and right so as to clamp the paper box for left and right positioning. In addition, the first left clamping plate 121 and the first right clamping plate 122 are respectively provided with a first front clamping plate 123 and a first rear clamping plate 124 that can cooperate with each other in opening and closing. The first front clamping plate 123 and the first rear clamping plate 124 on the left and right sides can be closed front and back to clamp the paper box for front and back positioning. When the first front clamping plate 123 and the first rear clamping plate 124 are separated front and back, they retreat and wait for the next operation. Moreover, the first front clamping plate 123 and the first rear clamping plate 124 on the left and right sides will also cooperate with the first left clamping plate 121 and the first right clamping plate 122 to open and close left and right. Similarly, the second carton positioning device 13 includes a second left clamping plate 131 and a second right clamping plate 132 that have a splitting and closing cooperation action. The second left clamping plate 131 and the second right clamping plate 132 are separated left and right so that the carton can be normally conveyed by the carton conveying mechanism 10, and the second left clamping plate 131 and the second right clamping plate 132 are closed left and right so as to clamp the carton for left and right positioning. In addition, the second left clamping plate 131 and the second right clamping plate 132 are respectively provided with a second front clamping plate 133 and a second rear clamping plate 134 that have a splitting and closing cooperation action. The second front clamping plate 133 and the second rear clamping plate 134 on the left and right sides can be closed front and back to clamp the carton for front and back positioning. When the second front clamping plate 133 and the second rear clamping plate 134 are separated front and back, they retreat and wait for the next operation. Moreover, the second front clamping plate 133 and the second rear clamping plate 134 on the left and right sides will also split and close left and right together with the second left clamping plate 131 and the second right clamping plate 132. The left and right, and front and back, clamping and positioning the carton, respectively, ensures more precise relative positioning during gluing and inner tray assembly. The left-right and front-back splitting and closing movements can be driven by pneumatic cylinders, or alternatively, by a motor 125 (such as a servo motor) coupled with a forward and reverse double-ended screw-nut mechanism 126. This allows for direct adaptation to different sizes and specifications through the drive's splitting and closing stroke. In the figure, the left-right splitting and closing movement is driven by motor 125, while the front-back splitting and closing movement is driven by a pneumatic cylinder. Cylinder 135 drives the rearward clamping plate back and forth toward the forward clamping plate. Furthermore, the initial forward and backward positions of the forward and rearward clamping plates can be adjusted as needed. Furthermore, the first left clamping plate 121 and the second left clamping plate 131 can be constructed as a single component, and similarly, the first right clamping plate 122 and the second right clamping plate 132 can be constructed as a single component, enabling synchronized operation.

[0047] The carton conveying mechanism 10 also includes a carton conveying drive motor 111 (such as a servo motor), which is connected to the carton conveyor belt 11. The carton conveyor belt 11 can be a suction conveyor belt. In addition, the carton conveying mechanism 10 adopts an intermittent conveying method, for example, the carton conveyor belt 11 conveys intermittently, so that the corresponding carton stays at the inner support box loading station 1 and the carton gluing station 14 for operation.

[0048] For another example, the inner support blank conveying mechanism 30 includes a blank conveyor belt 36, on which blank unit placement matching components 31 are arranged in sequence along its conveying direction, so that a single inner support blank can be stably placed on the blank unit placement matching component 31, so that the inner support can be stably transported on the blank conveyor belt 36 and smoothly reach the blank positioning station 3; the inner support blank can be manually placed on the blank unit placement matching component 31 of the inner support blank conveying mechanism 30 (a limit support plate 369 is provided in the figure to facilitate smooth and accurate manual placement), or it can be placed on it by other means such as a robot.

[0049] Further optimization is also provided, for example, that the blank conveyor belt 36 includes a first conveyor belt 361 and a second conveyor belt 362 arranged side by side, that is, the first conveyor belt 361 and the second conveyor belt 362 convey the inner support blank forward side by side, and the blank unit placement matching component 31 includes a front limit plate 32 and a rear limit plate 33, wherein the front limit plate 32 is installed on the first conveyor belt 361, and the rear limit plate 33 is installed on the second conveyor belt 362, and a blank placement matching space is provided between the front limit plate 32 and the rear limit plate 33 for the inner support blank to be placed stably, and the posture position of the inner support blank is relatively uniform and stable; in addition, the front and rear limit plates 32 and the rear limit plates 33 are relatively adjustable in their front and rear positions on the blank conveyor belt 36 (on the first conveyor belt 361 and the second conveyor belt 362 respectively), so that they can be adjusted to adapt to different specifications and batches of inner supports, and can be disassembled and assembled with screw fasteners (can be equipped with an adjustable long hole 360 ​​or multiple adjustment holes in different positions) to cooperate with the adjustment setting.

[0050] Among them, the first conveyor belt 361 and the second conveyor belt 362 adopt a synchronous blank feeding mode, that is, when conveying cartons normally, they run synchronously to cooperate in feeding; the first conveyor belt 361 and the second conveyor belt 362 adopt an asynchronous adjustment and shifting mode, that is, before conveying cartons normally, the first conveyor belt 361 and the second conveyor belt 362 can be asynchronously operated to cooperate in relative shift adjustment. For example, the first conveyor belt 361 is equipped with a first front pulley 363 and a first rear pulley 367, and the second conveyor belt 362 is equipped with a second front pulley 364 and a second rear pulley 368. The first front pulley 363 is connected to the front rotating shaft 365 in a transmission manner, and the front rotating shaft 365 will support and drive the first front pulley 363 to operate. The second front pulley 364 is connected to the front rotating shaft 365 through an elastic sleeve 366. The second front pulley 364 is supported and driven to operate by the front rotating shaft 365, and the second front pulley 364 is locked and loosened with the front rotating shaft 365 through the elastic sleeve 366, wherein the elastic sleeve 366 and the front rotating shaft 365 can be loosened by a top screw or other structures of an elastic opening groove. When loosened, the second front pulley 364 and the front rotating shaft 365 can be disengaged (loosened) and can no longer be driven by the front rotating shaft 365. Operation, when locked, the second front pulley 364 is fixedly locked with the front rotating shaft 365 and can be driven to operate; wherein, the front rotating shaft 365 is connected to the billet driving motor 37 in a transmission manner, and the billet driving motor 37 cooperates to drive the front rotating shaft 365 to operate, and the inner support billet conveying mechanism 30 adopts an intermittent conveying method. The billet driving motor 37 can use a servo motor to facilitate intermittent conveying, and of course other motors can also be used; in addition, the first rear pulley 367 and the second rear pulley 368 are connected to the rear axle, and the rear axle cooperates to support the first rear pulley 367 and the second rear pulley 368 to operate, and bearings are respectively provided between the first rear pulley 367 and the second rear pulley 368 and the rear axle, which not only cooperates to support the first rear pulley 367 and the second rear pulley 368 to synchronously operate and feed on the rear axle and asynchronously adjust and shift. The adjustment and shift range is larger. In addition, a supporting auxiliary rod 38 is arranged above the blank conveyor belt 36 along its conveying direction. The supporting auxiliary rod 38 can be configured in quantity, shape, and path according to needs. In the figure, a straight rod can be selected (arranged in a straight line from back to front along the conveying direction of the blank conveyor belt 36) to cooperate with the auxiliary front limit plate 32, the rear limit plate 33, etc., to assist in supporting the inner blank and increase the stability of the inner blank conveying.

[0051] The following optimization will also be adopted: the inner support forming station 2 is equipped with a supporting platform 21, and the inner support blank (that is, the unformed material, which can be called blank) can be placed on the supporting platform 21, and the supporting platform 21 cooperates to support it (the inner support blank) so that the blank can be input and placed for subsequent production; the supporting platform 21 is equipped with a lifting upper folding rod 22, and the lifting upper folding rod 22 is used to rise to cooperate with the upper folding, and can participate in pushing the blank on the supporting platform 21 upward to cooperate with the folding (folding the material, such as folding and hemming some areas of the material) for forming, and (at the inner support forming station 2) the blank can be supported. The platform 21 is provided with a lifting bracket 41 above, which can cooperate with the lifting operation. The lifting bracket 41 is provided with a material receiving and forming cavity 20, which is lifted and lowered together with the lifting bracket 41 to cooperate with the inner support folding molding and transfer (even assembly). The material receiving and forming cavity 20 is configured correspondingly to the lifting upper folding rod 22 so that the blank on the supporting platform 21 can be formed into an inner support finished product structure during operation. The lifting upper folding rod 22 moves upward (i.e. rises) to push the blank (on the supporting platform 21) into the corresponding material receiving and forming cavity 20 above to cooperate The material is folded and formed to form the inner support finished product; moreover, the receiving and forming cavity 20 is equipped with a lifting and pressing material outlet cavity component 43, which is connected and installed on the lifting bracket 41. The lifting and pressing material outlet cavity component 43 and the receiving and forming cavity 20 can not only move up and down together with the lifting bracket 41, but the lifting and pressing material outlet cavity component 43 can also perform additional lifting actions alone in the receiving and forming cavity 20 on the lifting bracket 41 so that it (the lifting and pressing material outlet cavity component 43) can cooperate in the inner support molding and output the formed inner support from the receiving and forming cavity 20 (), The device 4 for transferring the finished inner tray into the box for assembly between workstations includes an intermediate transfer seat 40, and a lifting bracket 41 is arranged on the intermediate transfer seat 40. The lifting bracket 41 (and the material receiving and forming cavity 20, the lifting and pressing material outlet cavity component 43, etc. thereon) can not only move up and down on the intermediate transfer seat 40, but also the lifting bracket 41 (and the material receiving and forming cavity 20, the lifting and pressing material outlet cavity component 43, etc. thereon) can perform intermediate transfer along with the intermediate transfer seat 40, thereby realizing the intermediate transfer of the inner tray after molding, directly intermediately transferring the molded inner tray, and intermediately transferring it to subsequent assembly operations.

[0052] The working principle of the optimized structure is as follows: after the inner support blank (i.e., the unformed material, which can be called blank) is placed on the support platform 21, the lifting upper folding rod 22 cooperates to push the blank into the receiving and forming cavity 20 (of the upper lifting bracket 41), and the blank is folded and folded accordingly to complete the inner support forming; then the upper folding rod descends and returns to its position (waiting for the next work), and the receiving and forming cavity 20 can not only cooperate with the inner support forming, but also receive and obtain the formed inner support; the inner support is received in the receiving and forming cavity 20 and rises with the lifting bracket 41, and is pushed into the receiving and forming cavity 2 0 can be cooperated with the lifting and pressing material discharge cavity component 43 (when descending) to output the formed inner support downward and out of the receiving and forming cavity 20; wherein, the lifting bracket 41 and the receiving and forming cavity 20 (and the formed inner support therein) above it and the lifting and pressing material discharge cavity component 43 can be transferred in the intermediate transfer seat 40, so that the formed inner support can be directly transferred to the subsequent process (such as the inner support assembly of the paper box), and the lifting and pressing material discharge cavity component 43 (when descending) cooperates to bring the receiving and forming cavity 20 close to (joint) the upward opening of the paper box, so that the subsequent inner support can be loaded into the paper box more smoothly. In this optimized structure, the unformed inner support can be directly formed and directly transferred and output in the intermediate transfer, so that the formed inner support can be directly transferred to the subsequent process (such as the inner support assembly of the paper box), thereby improving the assembly efficiency. The inner support formed in the intermediate transfer process (such as folding and folding) remains in a formed state in the receiving and forming cavity 20 and is not easy to fall apart and is relatively more stable, thereby improving the assembly stability.

[0053] The intermediate transfer seat 40 is transferred and connected between the inner tray forming station 2 and the inner tray boxing station 1 to facilitate the intermediate transfer of the formed inner tray to the inner tray boxing station 1 for subsequent processes (i.e., assembly of the inner tray with a paper box). For example, the intermediate transfer seat 40 is configured on an intermediate transfer translation guide rail 401, and the intermediate transfer seat 40 is transmission-connected to a translation drive component 401 (such as a servo motor). The translation drive component 401 cooperates to drive the intermediate transfer seat 400 to translate stably (horizontally) along the intermediate transfer translation guide rail 401 to facilitate transfer and connection between the stations. Belt drive or other structures can be used to connect them. In the figure, the intermediate transfer translation guide rail 401 is arranged horizontally, and the blank placement station 3, the inner tray forming station 2, and the inner tray boxing station 1 are also arranged horizontally in sequence.

[0054] The blank transfer device 5 between the workstations includes an inner support blank transfer component 50, which cooperates to transfer the inner support blank from the blank positioning station 3 to the inner support molding station 2, such as transferring and placing it on the support table 21 of the inner support molding station 2. There are many types of inner support blank transfer components 50. For example, the inner support blank transfer component 50 adopts a translational pushing component or a translational lifting and unloading component; for example, the translational pushing component adopts a translational pushing method to push the prepared inner support blank in place onto the support table 21. For example, the translational pushing component in the figure adopts a push rod 51, and the push rod 51 is connected to a translational pushing frame 52. The translational pushing frame 52 is driven by a translational pushing drive component 54 (such as a cylinder or a module of a distribution motor) to translate. , the figure shows horizontal translation. In addition, the push rod 51 can also cooperate with some structures that support the blank; for example, the translational lifting and unloading material component adopts a translational lifting and unloading combined operation mode to lift the prepared inner support blank in place, transfer it to the inner support molding station 2, and then lower it to the support table 21. It performs translational back and forth movements, lifting and unloading movements, and unloading movements. A suction nozzle can be configured to suck and release the blank to cooperate with unloading, such as using an industrial robot with a suction nozzle for picking and placing.

[0055] For example, a side frame 421 is provided on the lifting bracket 41, and the side frame 421 encloses and forms a material receiving and forming cavity 20 with an opening facing downward. For example, at least one of a side panel 422, a side rod, and a side block 423 is provided on the lifting bracket 41 as the side frame 421. A channel or a downward recess 4231 can be additionally provided on the side frame 421. The channel or recess 4231 can be used for the internal lifting and pressing cavity component 43 to connect with other components to extend out of the material receiving and forming cavity 20 (set according to needs); for example, in the figure, the lifting bracket 41 is provided with side panels 422 at the left and right positions, a side panel 422 at the front position, and a side block 423 with a downward recess 4231 at the rear position.

[0056] The lifting and pressing material discharging chamber component 43 is also provided with a downward suction nozzle and / or the lifting and folding material rod 22 is provided with an upward suction nozzle. The technology of the suction nozzle sucking and releasing the material is relatively mature. This matching structure can maintain the relative position of the inner support from being skewed during the inner support molding and / or the inner support is output downward and disengaged, making the subsequent inner support assembly more accurate. The lifting and pressing material discharging chamber component 43 is also installed and connected to a forming auxiliary mold 44. The forming auxiliary mold 44 can be raised and lowered together with the lifting and pressing material discharging chamber component 43. The forming auxiliary mold 44 (such as an auxiliary block, etc.) is used to match and support the inner support to make molding more stable, and the position of the inner support on the receiving molding chamber 20 is not easy to deviate; even some forming auxiliary molds 44 can be set at or outside the notch 4231 to adapt to inner supports of different styles and structures.

[0057] There are many structural forms for the support platform 21 used to support the inner support blank. For example, the support platform 21 includes a left support strip 23 and a right support strip 24. When the inner support blank is placed on the support platform 21, the left support strip 23 and the right support strip 24 cooperate to support the placed inner support blank, which can support the left and right edges of the bottom of the inner support blank. The lifting upper folding rod 22 is distributed between the left support strip 23 and the right support strip 24. In this matching structure, not only the lifting upper folding rod 22 is distributed according to demand to match the inner support molding of different styles, structures or specifications, but also the left support strip 23 and the right support strip 24 are arranged to support the inner support blank. The spacing between 24 can also be adjusted according to needs to meet different specifications, and it can be more convenient for the inner support blank to be pushed in horizontally; for example, the upper side of the left support edge strip 23 and the right support edge strip 24 is set as the inner support blank transfer and translation push-in position, and the inner support blank is transferred and pushed into this position, for example, the inner support blank transfer component 50 (such as a translational pushing component) cooperates to push the inner support blank into this position for transfer. During the pushing process, the left support edge strip 23 and the right support edge strip 24 cooperate to support the left and right edge positions of the inner support blank so that it can be pushed in smoothly.

[0058] In addition, the left and right support rails 23 and 24 are each equipped with a push-in stopper 25 to prevent the stock from swerving. The position where the inner stock is transferred and pushed in is located between the left and right stopper 25. The stopper 25 prevents the stock from swerving as it is pushed in. The support platform 21 is also equipped with a feed stopper 26, which cooperates with the stopper 26 to ensure more accurate positioning of the inner stock during its translation. The stopper 25 is located on the left and right support rails 23 and 24, respectively, and the stopper 26 is connected to the left and / or right support rails 23 and 24, resulting in a compact installation structure and simultaneous left-right position adjustment. The stopper 26 can be adjusted relative to the front and back positions of the support platform 21, such as by disassembly (e.g., by chute fastener disassembly), allowing for adaptability to varying material specifications and dimensions.

[0059] The left support strip 23 and the right support strip 24 are spaced apart to accommodate the needs of different sizes of inner support molding. There are many ways to adjust the spacing, such as using a screw rod with a handwheel 27 and a nut in a relatively mature structure.

[0060] The lifting and folding rods 22 are distributed on the mounting frame 28. The position and relative height of the lifting and folding rods 22 can be adjusted as needed. The lifting and folding rods 22 are vertically arranged. The mounting frame 28 is connected to a first lifting drive component, which drives the mounting frame 28 and the lifting and folding rods 22 thereon to move upward and downward. The lifting bracket 41 is connected to a second lifting drive component, which cooperates with the second lifting drive component to drive the lifting bracket 41 to move upward and downward. The lifting and pressing and discharging cavity component 43 is connected to a third lifting drive component, which cooperates with the third lifting drive component to drive the lifting and pressing and discharging cavity component 43 to move upward and downward.

[0061] The structural technology of lifting drive and transmission is relatively mature. For example, the first lifting drive component, the second lifting drive component, and the third lifting drive component respectively include a cylinder or an electric cylinder; as shown in the figure, the first lifting drive component includes a first driving motor 29, and a first screw-nut transmission mechanism is connected between the first driving motor 29 and the mounting bracket 28, that is, the first driving motor 29 drives the first screw-nut transmission mechanism, and then the first screw-nut transmission mechanism drives the mounting bracket 28 to lift and lower. Usually, the first driving motor 29 drives the first screw 291 in the first screw-nut transmission mechanism, and the first screw 291 in the first screw-nut transmission mechanism is connected to the first nut 292 for transmission, and the first nut 292 of the first screw-nut transmission mechanism is set It is placed on the mounting frame 28. For example, the mounting frame 28 has a top plate 282, a guide column 283 and a bottom plate 284. The top plate 282 and the bottom plate 284 are connected by the guide column 283. The lifting upper folding rod 22 is set on the top plate 282, and the first nut 292 is set on the bottom plate 284. The first drive motor 29, the first screw rod 291, the supporting platform 21, etc. can be set on the bottom bracket 200. The guide column 283 can also be used to cooperate with the lifting vertical guide, such as providing a guide sleeve on the bottom bracket 200 for the guide column 283 to lift and lower vertically. Similarly, the second lifting drive component includes a second drive motor 48, and the second drive motor 48 is connected to the lifting bracket 41 by a second screw rod and nut transmission mechanism, that is, the second drive motor 48 Drives the second screw rod and nut transmission mechanism, and then the second screw rod and nut transmission mechanism drives the lifting bracket 41 to move up and down. Usually, the second drive motor 48 drives the second screw rod 481 in the second screw rod and nut transmission mechanism. The second screw rod 481 in the second screw rod and nut transmission mechanism is transmission-connected with the second nut 482. The nut 482 of the second screw rod and nut transmission mechanism is arranged on the lifting bracket 41. For example, the second drive motor 48 is arranged on the intermediate transfer seat 40. The lifting bracket 41 includes an upper plate 413, a connecting rod 414 and a lower plate 415. The upper plate 413 and the lower plate 415 are connected by the connecting rod 414. The second nut 482 can be arranged on the upper plate 413. The third lifting drive component (such as its third drive motor 49) can It is arranged on the upper plate 413, and the lower plate 415 can be used for setting the material receiving and forming cavity 20, the side frame 421, etc.; similarly, the third lifting drive component includes a third driving motor 49, and the third driving motor 49 and the lifting and pressing material out of the cavity component 43 are driven by a third screw nut transmission mechanism, that is, the third driving motor 49 drives the third screw nut transmission mechanism, and then the third screw nut transmission mechanism drives the lifting and pressing material out of the cavity component 43 to lift and lower. Usually, the third driving motor 49 drives the third screw 491 in the third screw nut transmission mechanism, and the third screw 491 in the third screw nut transmission mechanism is transmission-connected with the third nut 492, and the third nut 492 of the third screw nut transmission mechanism is arranged on the lifting and pressing material out of the cavity component 43;For example, the third drive motor 49 is mounted on the upper plate 413, the third screw rod 491 is positioned on the lifting bracket 41 (e.g., between the upper plate 413 and the lower plate 415), and the lifting and pressing chamber assembly 43 is connected to the upper pull plate 46 via a guide rod 45. The third screw nut 492 is mounted on the pull plate 46, and a guide sleeve is provided on the lifting bracket 41 (e.g., on the lower plate 415) to provide vertical guidance for the guide rod 45. Each drive motor can be a servo motor, allowing for more precise control of the lifting and lowering operation as needed. The lifting and lowering stroke can also be customized without requiring structural adjustments, making it more convenient. The lifting and pressing chamber assembly 43 can even rise in tandem with the inner support blank as it is pushed upward into the receiving and forming chamber 20, supporting the upper side of the inner support blank during forming, thereby ensuring more stable inner support forming.

[0062] The mounting frame 28 is equipped with a first vertical guide 281, and the lifting bracket 41 is equipped with a second vertical guide 411, which is connected to the intermediate transfer seat 40. The lifting and pressing cavity component 43 is equipped with a third vertical guide 431, which is connected to the lifting bracket 41. The third vertical guide 431 cooperates with the lifting bracket 41 through corresponding guide devices (such as guide rails, sliders, guide columns, guide rods, guide sleeves, and other guiding structures) to ensure more stable vertical lifting. The second drive motor 48 can be mounted on the intermediate transfer seat 40, and the third drive motor 49 can be mounted on the lifting bracket 41.

[0063] In addition, the (inner support) blank placement station 3 is equipped with a blank unit placement matching component 31, which allows a single inner support blank to be stably and smoothly placed in place. The blank unit placement matching component 31 can be located at the blank placement station 3. A single inner support blank is placed on the blank placement station 3 to facilitate smooth placement of the inner support blank. The inner support blank can be manually placed on the blank unit placement matching component 31 of the blank placement station 3, or it can be transported there by other means, such as a robot. Among them, the blank input end of the support platform 21 corresponds to the blank output end of the blank placement station 3 in front and back. For example, the inner support blank transfer translation push position corresponds to the blank placement matching space in front and back (aligned, docked), which facilitates the inner support blank transfer component 50 (such as a translational push component, such as a push rod 51) to translate and push the inner support blank for transfer, so that the inner support blank is output from the output end of the blank placement station 3 and input from the blank input end of the support platform 21.
