Description

Technical Field

[0001] This application relates to the field of paper product manufacturing technology, and in particular to a paperboard product manufacturing equipment and process. Background Technology

[0002] Our environmentally friendly, biodegradable cardboard packaging trays are molded from natural plant fiber pulp and include a range of products such as dinner plates, fresh food trays, and barbecue trays. They possess excellent oil and water resistance and high-temperature resistance, and are fully compostable, naturally decomposing into organic fertilizer within 180 days, effectively reducing plastic pollution.

[0003] Currently, referring to Figure 1 The cardboard product 57 features a multi-toothed structure 58 around its perimeter, significantly enhancing its overall structural strength and morphological stability through structural reinforcement. The presence of the toothed lines 58 results in a more rational distribution of material stress, effectively resisting deformation caused by external loads, especially in scenarios involving stacking or containing heavy objects, maintaining the integrity of the product structure. In the production process, the cardboard product 57 employs an integrated thermoforming process: the cardboard raw material is precisely placed within a customized thermoforming mold, and through mechanical pressure and simultaneous heat transfer within the mold cavity, the raw material is formed in a single step.

[0004] However, there are technical challenges in the toothed forming stage: the flat paperboard raw material needs to be transformed into a raised toothed shape under hot pressing. During the hot pressing process, the paperboard raw material is compressed from a flat shape to a three-dimensional shape. At this time, the paperboard fibers are easily stretched randomly and irregularly, which reduces the structural strength of the flat product and may even cause the product to crack. Summary of the Invention

[0005] In order to improve the structural strength of paperboard products and reduce product cracking, this application provides paperboard product manufacturing equipment and process.

[0006] Firstly, the paperboard product manufacturing equipment provided in this application adopts the following technical solution:

[0007] A paperboard product manufacturing equipment includes an unwinding mechanism, a coating mechanism, a toothing mechanism, a hot pressing mechanism, and a collecting mechanism. A paper roll is placed in the unwinding mechanism, which drives the paper roll to rotate and unwind paperboard raw material. The coating mechanism applies auxiliary materials to the surface of the paperboard raw material. The toothing mechanism presses tooth lines into the paperboard raw material. The hot pressing mechanism hot presses the paperboard raw material after the tooth lines are pressed and cuts off the waste material at the edge of the paperboard product. The collecting mechanism collects the hot-pressed paperboard product and the cut edge waste.

[0008] By adopting the above technical solution, during the production of paperboard products, the unwinding mechanism feeds in the paperboard raw material, the coating mechanism first applies auxiliary materials to the paperboard raw material, the serration mechanism then creases serrations onto the paperboard raw material, and finally the hot pressing mechanism hot-presses the paperboard raw material to obtain the paperboard product. This setup, by first creases serrations onto the paperboard raw material and then hot-presses it, solves the problem of disordered and irregular elongation of paperboard fibers when the paperboard raw material is transformed from a flat surface to a three-dimensional structure, thereby improving the structural strength of the paperboard product and reducing the likelihood of cracking.

[0009] Preferably, the unwinding mechanism includes an unwinding frame, an unwinding roller, and a first driving member. The paper roll is mounted on the unwinding roller, the unwinding roller is rotatably mounted on the unwinding frame, and the first driving member is mounted on the unwinding frame and is connected to the unwinding roller for transmission.

[0010] By adopting the above technical solution, the first driving component drives the unwinding roller to rotate on the unwinding frame, and the unwinding roller drives the paper roll to rotate, thereby enabling continuous feeding of paperboard raw materials.

[0011] Preferably, the coating mechanism includes a coating tank, a driven roller, a coating roller, a doctor blade, and a second driving member. The driven roller is rotatably mounted on the coating tank, and the coating roller is rotatably mounted inside the coating tank. The coating roller is located below the driven roller and abuts against it. The doctor blade is mounted inside the coating tank and located to the side of the coating roller. The second driving member is mounted on the coating tank and is connected to the coating roller for transmission. The paperboard raw material passes between the driven roller and the coating roller.

[0012] By adopting the above technical solution, the second driving component drives the coating roller to rotate in the coating tank. The coating roller drives the driven roller to rotate and convey the paperboard raw material. During the rotation of the coating roller, the auxiliary material in the coating tank adheres to the surface of the coating roller. During the movement of the auxiliary material driven by the coating roller, the scraper scrapes off the excess coating on the surface of the coating roller. Then the coating roller drives the auxiliary material to be applied to the surface of the paperboard raw material.

[0013] Preferably, the tooth-pressing mechanism includes a worktable, a mounting frame, a third driving component, a circular tooth cutter, a first lifting component, and a straight tooth cutter. The mounting frame is fixedly mounted on the worktable, the circular tooth cutter is rotatably mounted on the mounting frame, the third driving component is mounted on the mounting frame and is used to drive the circular tooth cutter to rotate, the worktable has a horizontal tooth groove corresponding to the circular tooth cutter, the straight tooth cutter is slidably mounted on the mounting frame, the first lifting component is mounted on the mounting frame and is used to drive the straight tooth cutter to move up and down, and the worktable has a vertical tooth groove corresponding to the straight tooth cutter.

[0014] By adopting the above technical solution, the coated paperboard material moves through the worktable, the third driving component drives the circular toothed knife to rotate, the circular toothed knife rotates in the horizontal toothed groove and presses out the horizontal toothed line on the paperboard material, and then the first lifting component drives the straight toothed knife to descend and move to the vertical toothed groove and press out the vertical toothed line on the paperboard material, so that the toothed line can be pre-pressed on the paperboard material.

[0015] Preferably, the hot pressing mechanism includes a base, a fixed mold, a top seat, a moving mold, a second lifting component, a cutter, and multiple guide pillars. The fixed mold is fixedly mounted on the base, the multiple guide pillars are fixedly mounted on the base, the top seat is fixedly mounted on the multiple guide pillars, the moving mold is slidably mounted on the multiple guide pillars, the cutter is fixedly mounted at the bottom of the moving mold, and the second lifting component is mounted on the top seat and connected to the moving mold.

[0016] By adopting the above technical solution, the product raw material after pre-pressing the tooth lines enters the base. The second lifting component drives the moving mold to move downward. After the moving mold and the fixed mold are closed, the cardboard raw material is hot-pressed. At the same time, when the moving mold and the fixed mold are closed, the moving mold drives the cutter to cut the cardboard raw material, thereby automatically cutting out cardboard products.

[0017] Preferably, the receiving mechanism includes a receiving seat, a movable frame, a receiving rack, and multiple suction cups. The movable frame is slidably disposed on the receiving seat in a horizontal direction, the receiving rack is slidably disposed on the movable frame in a vertical direction, and the multiple suction cups are disposed at the bottom of the receiving rack.

[0018] By adopting the above technical solution, after the hot pressing mechanism completes the hot pressing, the moving frame drives the receiving frame to move into the hot pressing mechanism. The receiving frame drives the suction cups to move downward. Multiple suction cups correspond one-to-one with multiple cardboard products. After the suction cups pick up the cardboard products, they take the cardboard products out of the hot pressing mechanism.

[0019] Preferably, the bottom of the spur cutter is slidably provided with a plurality of first pressing teeth, and the spur cutter is provided with a plurality of first elastic elements for pulling the first pressing teeth into the spur cutter. A slot is provided on the side wall of the first pressing teeth, a locking block is slidably provided in the spur cutter, and a second elastic element is provided in the spur cutter for pushing the locking block into the slot. A gear is rotatably provided on the side wall of the first pressing teeth, and a lever is provided on the gear. A rack is slidably provided in the spur cutter for meshing with the gear, and a pusher is provided at the bottom of the rack for pushing the locking block out of the slot.

[0020] By employing the above technical solution, the first pressing tooth is pushed downwards by a lever, causing the second elastic element to push the locking block into the slot. The locking block locks the first pressing tooth, allowing its bottom end to extend into the spur cutter. The spur cutter then moves the first pressing tooth downwards into the longitudinal tooth groove, thus pressing out the longitudinal tooth. When different lengths of longitudinal tooth lines need to be pressed, the first pressing tooth is pushed downwards by the lever, causing it to extend out of the spur cutter. Rotating the lever upwards causes the lever to move the rack downwards via a gear. The rack then moves the push block downwards, pushing the locking block out of the slot. At this point, the first elastic element pulls the first pressing tooth back into the spur cutter. This design allows for free adjustment of the number of first pressing teeth extending from the bottom of the spur cutter, thereby adjusting the length of the pressed longitudinal tooth.

[0021] Preferably, the outer periphery of the circular toothed cutter is provided with a sliding groove, a plurality of slide seats are slidably disposed in the sliding groove, a limit seat is detachably fixedly disposed in the sliding groove, a second pressing tooth is detachably disposed on each slide seat, a slot is provided in the slide seat, a locking groove is provided at the end of the slot in the slide seat, a rod is disposed on the second pressing tooth, a locking block is disposed on the side wall of the rod, the rod and the locking block are slidably disposed in the slot, and the locking block is engaged in the locking groove.

[0022] By employing the above technical solution, the circular toothed cutter drives the second pressing tooth to rotate, thus pressing out transverse tooth lines. When it is necessary to press transverse tooth lines of different lengths, first remove the limiting seat so that multiple slides can slide within the slide groove. Then, install or remove the second pressing tooth, insert the insert rod into the slot, and rotate the second pressing tooth so that the locking block enters the locking groove, thus installing the second pressing tooth on the slide. Finally, install the limiting seat within the slide groove. The limiting seat pushes multiple slides to move, causing adjacent second pressing teeth to abut against each other. The limiting seat abuts against the slide and restricts the movement of the slide within the slide groove, thereby limiting the second pressing tooth. With this configuration, the number of second pressing teeth on the circular toothed cutter can be adjusted, thereby adjusting the length of the pressed transverse tooth lines.

[0023] Secondly, the paperboard product manufacturing process provided in this application adopts the following technical solution:

[0024] A paperboard product manufacturing process, using the aforementioned paperboard product manufacturing equipment, includes the following steps: S1: continuously conveying paperboard raw materials using an unwinding mechanism; S2: applying auxiliary materials to the surface of the paperboard raw materials using a coating mechanism; S3: pressing serrations onto the paperboard raw materials using a serration pressing mechanism; S4: hot-pressing multiple paperboard products using a hot-pressing mechanism; S5: collecting the hot-pressed paperboard products and waste materials using a collecting mechanism.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By using a toothed crimping mechanism, toothed lines are first pressed into the paperboard raw material, and then the paperboard raw material is hot-pressed. This reduces the problem of disordered and irregular elongation of paperboard fibers when the paperboard raw material is transformed from a flat surface to a three-dimensional shape, thereby improving the structural strength of paperboard products and reducing the occurrence of product cracking.

[0027] 2. Using the first pressing tooth, the lever is used to push the first pressing tooth downwards. The second elastic element pushes the locking block into the slot, locking the first pressing tooth so that its bottom end extends into the spur cutter. The spur cutter moves the first pressing tooth downwards into the longitudinal tooth groove, thus pressing out the longitudinal tooth line. When different lengths of longitudinal tooth lines need to be pressed, the lever is used to push the first pressing tooth downwards, causing it to extend out of the spur cutter. The lever is then rotated upwards, causing the gear to move the rack downwards. The rack moves the push block downwards, pushing the locking block out of the slot. At this time, the first elastic element pulls the first pressing tooth back into the spur cutter. The number of first pressing teeth extending from the bottom of the spur cutter can be freely adjusted, thereby adjusting the length of the pressed longitudinal tooth line.

[0028] 3. The second pressing tooth, driven by the circular toothed cutter, rotates to press out transverse teeth. When pressing transverse teeth of different lengths, first remove the limiting seat to allow multiple slides to slide within the groove. Then, install or remove the second pressing tooth, insert the insert rod into the slot, and rotate the second pressing tooth to allow the locking block to enter the locking groove. The second pressing tooth can then be installed on the slide. Finally, install the limiting seat within the groove. The limiting seat pushes multiple slides to move, causing adjacent second pressing teeth to abut against each other. The limiting seat abuts against the slides and restricts their movement within the groove, thus limiting the second pressing tooth. The number of second pressing teeth on the circular toothed cutter can be adjusted, thereby adjusting the length of the pressed transverse teeth. Attached Figure Description

[0042] The following is in conjunction with the appendix Figures 2-12 This application will be described in further detail.

[0043] Example 1:

[0044] This application discloses a paperboard product manufacturing equipment.

[0045] Reference Figure 2 A paperboard product manufacturing equipment includes an unwinding mechanism 1, a coating mechanism 2, a toothed crimping mechanism 3, a hot pressing mechanism 4, and a take-up mechanism 5.

[0046] First, the paper roll is placed in the unwinding mechanism 1, which rotates the roll to smoothly release the paperboard raw material, providing a continuous material supply for subsequent processing. Before the paperboard raw material enters the next process, the coating mechanism 2 evenly coats the surface of the raw material with auxiliary materials. These materials not only enhance the paperboard's moisture-proof and corrosion-resistant properties but also provide a better foundation for subsequent serration and hot-pressing processes. Next, the serration mechanism 3 begins operation, pressing neat serrations onto the coated paperboard raw material.

[0047] After the serrations are completed, the cardboard raw material is conveyed to the hot pressing mechanism 4. The hot pressing mechanism 4 performs hot pressing on the cardboard raw material after the serrations are formed, using high temperature and pressure to make the structure of the cardboard raw material more compact and improve its overall strength. On the other hand, it can also precisely cut off waste material from the edges of the cardboard product, ensuring the accuracy of the product dimensions. Finally, the collecting mechanism 5 collects the hot-pressed cardboard product and the waste material generated from the edge cutting, achieving efficient separation of finished product and waste material, and facilitating subsequent recycling and reuse of the waste material.

[0048] During the production process, the paperboard raw material is first treated with toothed lines and then hot-pressed. This can effectively reduce the problem of disorderly and irregular elongation of paperboard fibers when the paperboard raw material is transformed from a flat surface to a three-dimensional shape, thereby improving the structural strength of the paperboard product and reducing the occurrence of product cracking.

[0049] Specifically, the unwinding mechanism 1 includes an unwinding frame 11, an unwinding roller 12, and a first drive member 13. The unwinding frame 11 is placed on the ground, and the unwinding roller 12 is rotatably mounted on the unwinding frame 11. The paper roll is sleeved on the unwinding roller 12. The first drive member 13 is fixedly mounted on the side of the unwinding frame 11, and the drive end of the first drive member 13 is connected to the unwinding roller 12. In this application, the first drive member 13 can be a servo motor. The first drive member 13 drives the unwinding roller 12 to rotate, and the unwinding roller 12 drives the paper roll to rotate, thereby continuously conveying the paperboard raw material.

[0050] Specifically, the coating mechanism 2 includes a coating tank 21, a driven roller 22, a coating roller 23, a doctor blade 24, and a second drive component 25. The coating tank 21 is placed on the ground and serves as a storage container for auxiliary materials, providing sufficient material for the entire coating process. The driven roller 22 is rotatably mounted on the coating tank 21, and the coating roller 23 is rotatably mounted inside the coating tank 21, directly below the driven roller 22, with both maintaining close contact.

[0051] This positional relationship creates favorable conditions for the conveying and coating of paperboard raw materials. When the paperboard raw materials pass between the driven roller 22 and the coating roller 23, stable transmission can be achieved through the combined action of the two. A scraper 24 is installed inside the coating tank 21 and located to the side of the coating roller 23. The scraper 24 trims the coating material on the surface of the coating roller 23. The second drive component 25 is fixed to the side wall of the coating tank 21 and forms a transmission connection with the coating roller 23, providing power for the rotation of the coating roller 23.

[0052] When the equipment is running, the second drive component 25 is activated, driving the coating roller 23 to rotate within the coating tank 21. Since the coating roller 23 and the driven roller 22 are in contact with each other, the rotation of the coating roller 23 will synchronously drive the driven roller 22 to rotate together. At this time, the paperboard raw material is smoothly conveyed forward under the clamping and rotation of the two.

[0053] As the paint roller 23 rotates, the auxiliary material in the paint tank 21 naturally adheres to its surface. As the paint roller 23 continues to rotate, the portion of the auxiliary material adhering to the surface gradually moves to the position of the scraper 24. The scraper 24 precisely scrapes off the excess auxiliary material from the surface of the paint roller 23, ensuring that the thickness of the auxiliary material on the surface of the paint roller 23 is uniform.

[0054] After being trimmed by the scraper 24, the coating roller 23 continues to rotate. When the surface carrying an appropriate amount of auxiliary material comes into contact with the passing paperboard raw material, the auxiliary material is evenly coated onto the surface of the paperboard raw material. This design not only ensures the uniformity of the auxiliary material coating and improves the performance of the paperboard raw material, but also avoids waste of auxiliary material and reduces production costs. At the same time, the coordinated rotation of the driven roller 22 and the coating roller 23 ensures that the paperboard raw material will not shift or wrinkle during the coating process, laying a good foundation for subsequent processes such as serration and hot pressing.

[0055] Multiple blowers 59 are installed between the glue coating mechanism 2 and the tooth pressing mechanism 3. The blowers 59 are located below the cardboard raw material and blow air onto the cardboard raw material to speed up the drying of the auxiliary materials on the cardboard raw material.

[0056] Reference Figure 3 and Figure 4 Specifically, the tooth-pressing mechanism 3 includes a worktable 31, a mounting bracket 32, a third drive component 33, a circular tooth cutter 34, a first lifting component 35, and a straight tooth cutter 36. The worktable 31 is placed on the ground, and three sliding plates 37 and 38 are slidably and adjustablely mounted on the worktable 31. The sliding directions of the first plate 37 and the second plate 38 are perpendicular to each other. The first plate 37 has a longitudinal tooth groove 7 along its own length, and the second plate 38 has a transverse tooth groove 6 along its own length.

[0057] Mounting bracket 32 ​​is fixedly mounted on workbench 31. First lifting component 35 is fixedly mounted on mounting bracket 32. Lifting plate 39 is fixedly mounted on the lifting end of first lifting component 35. Three straight tooth cutters 36 are mounted, and the three straight tooth cutters 36 are slidably and adjustablely mounted on the bottom wall of lifting plate 39. The three straight tooth cutters 36 correspond one-to-one with three first slide plates 37. The straight tooth cutters 36 and the first slide plates 37 are adjustable in the same direction, and multiple first pressure teeth 8 are mounted on the bottom of the straight tooth cutter 36. In this application, the first lifting component 35 can be a cylinder.

[0058] After the cardboard raw material is coated with auxiliary material, it enters the worktable 31. The first lifting component 35 drives the straight toothed knife 36 to move downward through the lifting plate 39. The straight toothed knife 36 drives the first pressing tooth 8 to move downward and enter the longitudinal tooth groove 7 of the first slide plate 37, so that longitudinal teeth can be pressed out on the cardboard raw material.

[0059] Reference Figure 5 The first pressing tooth 8 is slidably installed vertically inside the straight tooth cutter 36. Multiple first elastic elements 9 are installed inside the straight tooth cutter 36, and each first elastic element 9 is fixedly connected to the top of the first pressing tooth 8. The first elastic elements 9 can pull the first pressing tooth 8 into the straight tooth cutter 36. A slot 10 is formed on each of the opposite side walls of the first pressing tooth 8, and the two slots 10 are interconnected. A locking block 14 is slidably installed on each of the opposite inner side walls of the straight tooth cutter 36. Multiple second elastic elements 15 are installed inside the straight tooth cutter 36, and the second elastic elements 15 abut against the ends of the locking blocks 14 away from the first pressing tooth 8. In this application, the first elastic element 9 can be a tension spring, and the second elastic element 15 can be a spring. When the first pressing tooth 8 moves downward and extends out of the straight tooth cutter 36, the second elastic elements 15 push the two locking blocks 14 into the slots 10, thereby locking and limiting the first pressing tooth 8, keeping it extended out of the straight tooth cutter 36, facilitating the pressing tooth 8 to press out the longitudinal tooth groove.

[0060] Reference Figure 5 and Figure 6 A gear 16 is rotatably mounted inside the first pressing tooth 8, and a torsion spring is installed inside the first pressing tooth 8 to drive the gear 16 to rotate and return to a horizontal state. A limit groove 48 is formed inside the gear 16, and a lever 17 is fixedly mounted on its outer wall. A limit block 40 is fixedly mounted inside the first pressing tooth 8, and the limit block 40 is slidably mounted in the limit groove 48 to limit the rotation angle of the gear 16. A rack 18 is slidably mounted inside the first pressing tooth 8, and the rack 18 meshes with the gear 16. A push block 19 is fixedly mounted at the bottom end of the rack 18, and the bottom end of the push block 19 is set with a sharp corner. The top and bottom ends of the two locking blocks 14 on the side closest to each other are both chamfered.

[0061] When it is necessary to press longitudinal teeth of different lengths, the lever 17 is moved downwards. At this time, the lever 17 is in a horizontal state, and the limiting block 40 is located at the end of the limiting groove 48, so that the gear 16 will not rotate. The lever 17 drives the first pressing tooth 8 to slide down the straight tooth cutter 36 through the gear 16. The second elastic element 15 will push the locking block 14 into the locking groove 10 to lock the first pressing tooth 8 firmly, thereby increasing the length of the longitudinal teeth.

[0062] Pushing lever 17 upwards causes gear 16 to rotate, which in turn causes rack 18 to slide downwards. Rack 18 then causes push block 19 to slide downwards, and push block 19, through its chamfer, pushes two locking blocks 14 to slide away from each other. When the two locking blocks 14 slide out of the slot 10, the first elastic element 9 pulls the first pressure tooth 8 back into the spur cutter 36, thereby reducing the length of the longitudinal tooth line.

[0063] This design allows for flexible control over the number of first pressing teeth 8 extending from the bottom of the straight tooth cutter 36, thereby enabling precise adjustment of the longitudinal tooth line length.

[0064] Reference Figure 3 , Figure 7 The third drive component 33 is fixedly mounted on the mounting bracket 32. A rotating shaft is rotatably mounted on the mounting bracket 32, and the rotating shaft is fixedly connected to the drive end of the third drive component 33. Three circular tooth cutters 34 are mounted, and the three circular tooth cutters 34 are slidably and adjustablely mounted on the rotating shaft. The three circular tooth cutters 34 correspond one-to-one with the three second slide plates 38. The adjustment direction of the circular tooth cutters 34 is the same as the adjustment direction of the second slide plates 38, and multiple second pressing teeth 56 are mounted on the outer periphery of the circular tooth cutters 34. In this application, the third drive component 33 can be selected as a servo motor.

[0065] After the straight toothed cutter 36 presses out longitudinal tooth lines, the third driving component 33 drives the three circular toothed cutters 34 to rotate through the rotating shaft. The circular toothed cutters 34 drive the second pressing tooth 56 to rotate. The second pressing tooth 56 rotates in the transverse tooth groove 6 of the second slide plate 38, thus pressing out transverse tooth lines on the cardboard raw material.

[0066] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 The outer peripheral wall of the circular toothed cutter 34 is provided with a sliding groove 20, and multiple sliding seats 26 are slidably installed in the sliding groove 20. Both the sliding groove 20 and the sliding seats 26 are T-shaped, and the second pressing teeth 56 are detachably installed on the sliding seats 26. The circular toothed cutter 34 is located in the sliding groove 20 and is detachably fixed with two limiting seats 27 by hand-tightening bolts 60. The two limiting seats 27 press the multiple sliding seats 26 against the sliding groove 20, so that the multiple second pressing teeth 56 remain stable on the circular toothed cutter 34.

[0067] The slide 26 has a slot 28, and the slide 26 has a locking groove 29 that communicates with the end of the slot 28. A rod 30 is fixedly installed on the second pressing tooth 56, and a locking block 34 is fixedly installed on the side wall of the rod 30. The rod 30 and the locking block 34 are slidably installed in the slot 28, and the locking block 34 can rotate into the locking groove 29.

[0068] When it is necessary to press transverse teeth of different lengths, a limiting seat 27 is removed, which releases the restraint on multiple slides 26, allowing the slides 26 to slide freely in the slide groove 20, providing operating space for the subsequent installation or removal of the second pressing tooth 56.

[0069] Subsequently, the second pressing tooth 56 is installed or removed according to the required length of the transverse tooth line. When installing the second pressing tooth 56, the insert rod 30 is accurately inserted into the slot 28 on the slide 26, and then the second pressing tooth 56 is rotated to allow the locking block 34 to smoothly enter the locking groove 29. Through the stable engagement between the locking block 34 and the locking groove 29, the second pressing tooth 56 can be firmly fixed on the slide 26. If disassembly is required, the second pressing tooth 56 is rotated in the opposite direction to allow the locking block 34 to exit the locking groove 29, and then the insert rod 30 is pulled out.

[0070] After installing or removing the second pressing tooth 56, the limiting seat 27 is reinstalled into the slide groove 20. During installation, the limiting seat 27 pushes multiple slides 26 to move, causing adjacent second pressing teeth 56 to abut against each other, achieving tight connection and positioning between the slides 26 and preventing rotation of the second pressing teeth 56. Simultaneously, the limiting seat 27 firmly abuts against the slides 26, effectively restricting the movement of the slides 26 within the slide groove 20, thus providing a stable limit for the second pressing teeth 56 and ensuring that they do not shift position during pressing. By flexibly adjusting the number of second pressing teeth 56 on the circular tooth cutter 34, precise control of the transverse tooth line length is achieved.

[0071] Reference Figure 11 Specifically, the hot pressing mechanism 4 includes a base 41, a fixed mold 42, a top seat 43, a moving mold 44, a second lifting member 45, a cutter 46, and multiple guide pillars 47. The base 41 is placed on the ground, and the four guide pillars 47 are fixedly installed at the four corners of the top wall of the base 41. The fixed mold 42 is fixedly installed on the top wall of the base 41, the top seat 43 is fixedly installed on the top of the four guide pillars 47, the moving mold 44 is slidably installed on the four guide pillars 47, and the cutter 46 is fixedly installed on the bottom wall of the moving mold 44. The second lifting member 45 is fixedly installed inside the top seat 43, and the lifting end of the second lifting member 45 is fixedly connected to the moving mold 44. In this application, the second lifting member 45 can be a cylinder.

[0072] The pre-pressed cardboard raw material is precisely conveyed onto the base 41, preparing it for subsequent hot pressing and cutting processes. The second lifting component 45 begins operation, smoothly lowering the moving mold 44. As the moving mold 44 descends, it gradually approaches the fixed mold 42 mounted on the base 41, ultimately achieving a tight mold closing. During the mold closing process, the closed space formed by the moving mold 44 and the fixed mold 42 applies high temperature and pressure to the cardboard raw material within, completing the hot pressing process. Simultaneously, at the instant the moving mold 44 closes with the fixed mold 42, it also drives the cutter 46 mounted on it to move. Driven by the moving mold 44, the cutter 46 precisely cuts the cardboard raw material, separating the excess portion from the formed cardboard product.

[0073] Specifically, the receiving mechanism 5 includes a receiving base 51, a movable frame 52, a receiving rack 53, and multiple suction cups 54. The receiving base 51 is placed on the ground, the movable frame 52 is slidably mounted on the receiving base 51 in the horizontal direction, the receiving rack 53 is slidably mounted on the movable frame 52 in the vertical direction, and the multiple suction cups 54 are fixedly mounted on the bottom of the receiving rack 53. A product box 49 is placed to the side of the receiving base 51, and a waste box 50 is placed to the side of the hot pressing mechanism 4. A paper shredder 55 is mounted on the waste box 50.

[0074] After the hot pressing mechanism 4 successfully completes the hot pressing and cutting process of the cardboard raw material, the material collection process is immediately started. At this time, the moving frame 52 begins to move, precisely moving the material collection frame 53 into the hot pressing mechanism 4 to reach the preset material collection position. Immediately afterwards, the material collection frame 53 drives the suction cup 54 installed on it to move downwards. The suction cup 54 is activated, generating suction force to firmly hold the corresponding cardboard product. The material collection frame 53 drives the suction cup 54 to rise, and then the moving frame 52 moves together with the material collection frame 53 and the adsorbed cardboard product, smoothly bringing the cardboard product out of the hot pressing mechanism 4. The suction cup 54 then puts the cardboard product into the product box 49. The cut waste enters the shredder 55, and the shredded waste falls into the waste box 50, thus facilitating the reuse of waste.

[0075] The implementation principle of a paperboard product production equipment according to an embodiment of this application is as follows: First, the paper roll is placed in the unwinding mechanism 1, which drives the paper roll to rotate, smoothly releasing the paperboard raw material and providing a continuous material supply for subsequent processing. Before the paperboard raw material enters the next process, the coating mechanism 2 evenly coats the surface of the paperboard raw material with auxiliary materials. These auxiliary materials not only enhance the paperboard's moisture-proof and corrosion-proof properties, but also provide a better foundation for subsequent serration and hot-pressing processes. Next, the serration mechanism 3 begins operation, pressing regular serrations onto the coated paperboard raw material.

[0076] After the serrations are completed, the cardboard raw material is conveyed to the hot pressing mechanism 4. The hot pressing mechanism 4 performs hot pressing on the cardboard raw material after the serrations are formed, using high temperature and pressure to make the structure of the cardboard raw material more compact and improve its overall strength. On the other hand, it can also precisely cut off waste material from the edges of the cardboard product, ensuring the accuracy of the product dimensions. Finally, the collecting mechanism 5 collects the hot-pressed cardboard product and the waste material generated from the edge cutting, achieving efficient separation of finished product and waste material, and facilitating subsequent recycling and reuse of the waste material.

[0077] During the production process, the paperboard raw material is first treated with toothed lines and then hot-pressed. This can effectively reduce the problem of disorderly and irregular elongation of paperboard fibers when the paperboard raw material is transformed from a flat surface to a three-dimensional shape, thereby improving the structural strength of the paperboard product and reducing the occurrence of product cracking.
