Description

Technical Field

[0001] The utility model relates to the technical field of molding machines, in particular to a dot-sheet baking paper cup molding machine. Background Art

[0002] As an important packaging material in the baking industry, paper cups are performing steadily in the current market and the demand is continuously increasing. However, the equipment available in the market for producing paper cups still has problems such as low automation level, poor paper compatibility, inaccurate and non-adjustable number of formed sheets, and insufficient forming accuracy. There are three main forms in the prior art: a simple cake paper cup molding machine, a cake paper cup molding machine, and an inclined-plane cake paper cup molding machine, but all three machines have defects.

[0003] For example, the simple cake paper cup molding machine only has a forming mechanism. During operation, workers need to manually put the paper into the forming mechanism for molding by pressing, which has problems such as low automation level, high manual labor intensity, and inability to specify the number of sheets. Although the cake paper cup molding machine has a paper feeding mechanism, a paper conveying mechanism, and a forming mechanism, the paper feeding mechanism is manual paper feeding, which has problems such as uncontrollable number of fed papers, high manual labor intensity, and low automation level; and after the paper is clamped to the molding position, the mold is directly closed without an alignment element or alignment facility, and the risk of insufficient forming accuracy is high. The inclined-plane cake paper cup molding machine has a paper storage mechanism, a clamping and conveying mechanism, and a molding structure. Although it has a higher automation level, in this technology, when the chuck completes the "clamping-conveying-placement" action, it needs to rotate an angle, which is inconvenient to operate, lacks an effective positioning cavity, and has problems of insufficient repeat accuracy.

[0004] Based on the above, the existing equipment for paper cups has problems of low automation level and high labor consumption, and there is no precision adjustment device during the molding process, resulting in insufficient accuracy of the formed products. Therefore, a dot-sheet baking paper cup molding machine is provided to solve the problems existing in the prior art. Content of the Utility Model

[0038] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0039] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0040] Embodiment

[0041] As Figures 1-10 As shown, the utility model provides a dot-sheet baking paper cup forming machine, which includes a frame 8, a paper feeding system 10, a pushing system 6, and a forming system 7 arranged on the frame 8. A lower die assembly 4 is arranged below the forming system 7, and a conveying track groove 5 is arranged at the upper end of the pushing system. One end of the conveying track groove 5 abuts against the paper outlet of the paper feeding system 10, and the other end of the conveying track groove 5 abuts against the lower die assembly 4.

[0042] The paper feeding system 10 is arranged on the frame 8 through a fixed base 85. Body plates 86 are arranged on both sides of the paper feeding system 10, and a back plate is arranged at the rear end. A bearing bracket 88 is arranged on the right body plate 86 through a fixed straight plate 87; a transmission system 9 is arranged outside the right body plate 86. The transmission system 9 includes a first motor 91, a second motor 92, and a driving wheel connected to the driving shaft of the second motor 92. The driving wheel is connected to a plurality of driven wheels 93 through a double-sided tooth synchronous belt, and the positions of the driven wheels 93 are correspondingly arranged with the positions of the elements to be driven in the paper feeding system 10. A protective housing is arranged outside the paper feeding system 10 and the transmission system 9.

[0043] The tensioning synchronous pulley 94 is arranged on the right body plate 86 through a tensioning assembly. The tensioning assembly includes a tensioning device shaft 95, a tensioning sheet metal 96, and a tension spring 97. The tensioning synchronous pulley 94 is arranged in the inner cavity of the tensioning sheet metal 96. One end of the tensioning sheet metal 96 is connected to the right body plate 86 through the tensioning device shaft 95, and the other end is connected to the tension spring 97. The other end of the tension spring 97 is fixed to the right body plate 86 through a tension spring screw 98; the tensioning synchronous pulley 94 relies on the tension spring 97 to provide stable tensioning ability, ensuring that the tension in the transmission system is appropriate, and improving the transmission efficiency; in addition, when the resistance of the driven pulley system is too large, there are impacts, vibrations, etc., the tension spring undergoes elastic deformation, and the tensioning synchronous pulley 94 performs displacement compensation, absorbing vibrations and impacts, preventing phenomena such as tooth skipping, reducing the wear and damage of the double-sided tooth synchronous belt and the driven wheels, and also protecting the motor and the driven pulley system.

[0044] The paper feeding system 10 includes a paper storage structure 1, a pre-paper feeding structure 2, and a paper feeding structure 3. The paper outlet end of the paper storage structure 1 abuts against the paper inlet end of the pre-paper feeding structure 2, and the paper outlet end of the pre-paper feeding structure 2 abuts against the paper inlet end of the paper feeding structure 3; this structure plays the functions of storing and quantitatively feeding paper. The specific operation process of this technical solution is as follows: Workers put the paper into the paper storage structure 1. Under the influence of the weight block or the self-weight of the paper, the paper falls to the lower end, and single sheets are sent out in the pre-paper feeding structure 2, and then enter the paper feeding structure 3, and are sent out by the paper feeding structure 3 to the card issuing machine to reach the next process.

[0045] The paper storage structure 1 includes a paper pressing sheet metal support 11 and a paper pressing sheet metal 12 symmetrically arranged on both sides of the paper pressing sheet metal support 11. The left and right limit of the paper is completed by the symmetrical distribution of the left and right paper pressing sheets 12; two groove-shaped openings are arranged in the middle and lower part of the paper pressing sheet metal 12 for installing the probe for detecting the remaining number of papers. A paper pressing sheet metal clamp 13 is arranged on the side of the paper pressing sheet metal 12 close to the paper pressing sheet metal support 11, and two paper pressing support shafts 14 are arranged on the paper pressing sheet metal support 11. The paper pressing support shaft 14 is connected to the front end of the paper pressing sheet metal 12 through the paper pressing sheet metal clamp 13, and both ends of the paper pressing support shaft 14 are connected to the body plate 86; a fine-tuning knob 15 is arranged on the paper pressing sheet metal clamp 13, which can adjust the position of the paper pressing sheet metal to complete the spatial size adjustment of the paper storage structure 1.

[0046] The lower end of the paper pressing sheet metal 12 is provided with a rear upper cover plate 16, the front end of the rear upper cover plate 16 is provided with a slot, and the rear end of the rear upper cover plate 16 is provided with a paper ejecting sheet metal 17, which is connected to the body plate 86 through an adjustment component, and mainly serves to receive the paper, and can cooperate with a counterweight block (a heavy object pressed on the paper after the paper is placed in the paper storage structure 1) or the paper's own weight to complete the upper and lower limits of the paper. When in use, the rear end paper ejecting sheet metal 17 lifts the tail of the paper so that the tail of the paper does not contact the friction belt at the bottom, which can effectively control the contact area between the paper and the friction belt, which is conducive to the paper being "rubbed" out in a single sheet, and facilitates the subsequent paper output process.

[0047] The adjustment component includes a clamping shaft block 18 and a paper ejecting sheet metal clamping shaft 19 and a paper placing positioning adjustment shaft 110 arranged on the clamping shaft block 18. The front end of the paper ejecting sheet metal clamping shaft 19 is connected to the paper ejecting sheet metal 17 and the rear end is connected to the back plate. Both ends of the paper placing positioning adjustment shaft 110 are connected to the body plate 86.

[0048] In the paper storage structure 1, two paper pressing sheets 12 are clamped on the paper pressing sheet metal bracket 11 by a paper pressing sheet metal clamp 13, and the tightness is controlled by a fine-tuning knob 15. At the same time, the rear end paper ejecting sheet metal 17 can adjust the tilting angle and the insertion depth through the rear end clamping shaft block 18. These two adjustable designs enable the paper storage structure 1 to adapt to papers of different materials, shapes and sizes, and has very excellent compatibility.

[0049] Two heating plates (not shown) are arranged on the back of the rear upper cover 16, which can heat and shape the paper in the pre-paper output process, effectively improve the problem of paper curling after being exposed to humid air after die-cutting, and reduce the scrap rate in the subsequent molding process.

[0050] The pre-paper output structure 2 is mainly used to emit single sheets of paper, including a paper pressing component and a conveying component arranged at the lower end of the rear upper cover plate 16. The paper pressing component includes a paper pressing wheel 21 and a paper pressing plate 22. The paper pressing plate 22 is installed on the paper pressing sheet metal bracket 11. A paper pressing plate fine-tuning component is arranged on the paper pressing plate 22. The paper pressing plate fine-tuning component includes a paper pressing fine-tuning knob 24 and a paper pressing fine-tuning screw 25. The paper pressing fine-tuning screw 25 is connected to the paper pressing plate 22. By rotating the paper pressing fine-tuning knob 24, the up and down movement of the paper pressing fine-tuning screw 25 is controlled, so as to control the up and down position of the paper pressing plate 22. The paper pressing wheel 21 is arranged at the lower end of the paper pressing sheet metal bracket 11. The end of the paper pressing plate 22 is set as a large R-angle structure. The paper pressing wheel 21 is set as a rubber-coated paper pressing wheel. The paper pressing wheel 21 abuts against the end of the paper pressing plate 22; a transmission shaft 26 is connected to the inner hole of the paper pressing wheel 21. Transmission shaft fine-tuning components 27 are arranged at both ends of the transmission shaft 26 for adjusting the position of the transmission shaft.

[0051] The transmission shaft 26 includes a large shaft and a small shaft. The large shaft and the small shaft are connected by a coupling 28. The free end of the small shaft is rotatably connected to the transmission shaft fine-tuning component 27; the free end of the large shaft passes through the bearing bracket of the right side plate 86 and is connected to the first motor 91. The first motor 91 is mainly responsible for driving the paper pressing wheel 21 to reverse to achieve the thick paper mode. It is independent of other movements and has the ability to start independently and customarily adjust the rotation speed.

[0052] The transmission shaft fine-tuning component 27 includes a transmission shaft fine-tuning knob 2701, a transmission shaft adjustment block 2703, a transmission shaft fine-tuning screw 2702 and a transmission shaft fine-tuning block 2705 which are connected in sequence from top to bottom. The transmission shaft adjustment block 2703 is connected to the body plate 86; the transmission shaft adjustment block 2703 is arranged at the connection of the transmission shaft fine-tuning screw 2702 and the transmission shaft fine-tuning knob 2701. The transmission shaft fine-tuning block 2705 is rotatably connected to the bottom of the transmission shaft fine-tuning screw 2702. A fine-tuning spring 2704 is arranged outside the transmission shaft fine-tuning screw 2702. The transmission shaft fine-tuning block 2705 is rotatably connected to the transmission shaft 26. The transmission shaft fine-tuning component 27 is connected to the body plate 86 and can be regarded as fixed. When the two ends of the transmission shaft fine-tuning knob 2701 rotate forward at the same time, the transmission shaft fine-tuning screw 2702 will move upward by means of thread cooperation, lifting the transmission shaft fine-tuning block 2705 upward, and vice versa.

[0053] In this structure, both the paper pressing plate 22 and the paper pressing wheel 21 can complete the adjustment of the paper pressing depth through the thread cooperation of the corresponding fine-tuning components to adapt to papers of various thicknesses. In addition, after the "thick paper mode" of this device is turned on, the rubber-coated paper pressing wheel will reverse relative to the paper emission direction and "rub" the stacked papers backward. At this time, the stacked papers that have not been separated will be misaligned front and back, realizing further paper separation, and solving the problem that thick papers are prone to stacked papers due to the large friction force between papers during friction paper output.

[0054] The conveying component includes a paper supporting belt 29 and a paper supporting belt bracket 210. The rear upper cover plate 16 is fixed on the paper supporting belt bracket 210. The left side of the paper supporting belt bracket 210 is screwed onto the left side body plate 86, and the right side is connected to the body plate 86 through a support block 211. A first driving shaft 212 is arranged at the rear end of the paper supporting belt bracket 210. One end of the first driving shaft 212 is connected to the left paper supporting belt bracket 210, and the other end is connected to a driven wheel at a corresponding position extending out of the right side body plate 86.

[0055] A first driven shaft 23 is arranged at the rear end of the paper supporting belt bracket 210. Both ends of the first driven shaft 23 are pressed against the side end of the paper supporting belt bracket 210 through tensioning screws. The paper supporting belt bracket 210 is provided with a notch at this position to leave a tensioning space. Tensioning synchronous pulley Tensioning synchronous pulley

[0056] The paper supporting belt 29 is arranged at the grooved part of the rear upper cover plate 16; the paper supporting belt 29 is higher than the rear upper cover plate 16, and the paper supporting belt 29 abuts against the end of the pressure paper plate 22 to ensure that the paper can be smoothly discharged. When the paper is stored in the paper storage structure 1, the front end of the paper will contact the paper supporting belt 29. When the paper supporting belt 29 is driven by the motor to rotate, it will rely on friction to "rub" the paper under the pressure paper plate. The end of the pressure paper plate 22 is designed with a large R corner. When the R corner is abutted, the papers will be misaligned front and back, and then "rubbed" out to complete the separation of the papers, realizing the discharge of single sheets of paper.

[0057] The paper discharging structure 3 sends single sheets of paper out of the paper discharging system, including an upper circular belt component and a lower circular belt component with opposite rotation directions. The upper circular belt component includes an upper circular belt supporting driving shaft 31 and an upper circular belt supporting driven shaft 32; two groups of upper circular belts 33 are arranged between the upper circular belt supporting driving shaft 31 and the upper circular belt supporting driven shaft 32. Both ends of the upper circular belt supporting driving shaft 31 are respectively connected to the left side body plate 86 and the bearing bracket 88 of the right side body plate 86 through a first circular belt fine-tuning component 34. The upper circular belt supporting driving shaft 31 at the position of the bearing bracket 88 extends out of the bearing bracket 88 and is connected to a driven wheel at a corresponding position. The upper circular belt supporting driven shaft 32 is arranged on the upper circular belt bracket 35. The front ends of both sides of the upper circular belt bracket 35 can form a movable hinge connection with the body plate 86 through support pins. Both ends of the upper circular belt supporting driven shaft 32 are connected to the body plate 86 through a second circular belt fine-tuning component 36. The structure of the first circular belt fine-tuning component 34 is the same as that of the transmission shaft fine-tuning component 27, and the mechanism of the second circular belt fine-tuning component 36 is the same as that of the pressure paper plate fine-tuning component.

[0058] The lower circular belt assembly includes a lower circular belt bracket 37 and two sets of lower circular belts 38 arranged on the lower circular belt bracket 37. A lower circular belt support driving shaft 39 and a lower circular belt support driven shaft 310 are arranged on the lower circular belt bracket 37. One end of the lower circular belt support driving shaft 39 is connected to the lower circular belt bracket 37, and the other end of the lower circular belt support driving shaft 39 extends out of the bearing bracket 88 of the right side body plate 86 and is connected to the corresponding driven wheel 93. Both ends of the lower circular belt support driven shaft 310 are connected to the lower circular belt bracket 37. Both sides of the lower circular belt bracket 37 are fixed to the body plate 86 by bolts and do not have the function of adjusting up and down. While the upper circular belt assembly has the function of adjusting up and down through the thread fit of the corresponding circular belt fine-tuning assembly.

[0059] In the paper output structure 3, the upper circular belt 33 and the lower circular belt 38 rotate in opposite directions during movement, further sending the single sheets of paper output by the pre-paper output structure 2 out of the paper output system and reaching another process position. And both the front and rear ends of the upper circular belt 33 have the function of adjusting up and down. Finally, the gap between the upper and lower circular belts can be adjusted to adapt to papers of different thicknesses. This design not only ensures the stability of paper transportation but also enhances the paper compatibility of the equipment.

[0060] When replacing the paper supporting belt 29, the circular belt and the rubber-coated paper pressing wheel in this structure, it is not necessary to remove the two end body plates 86. Only the support block 211, the bearing bracket 88 and the fixed straight plate 87 need to be removed first, and then the corresponding shafts are removed to realize the replacement of the above components, which can greatly facilitate the later maintenance work.

[0061] A lower die assembly 4 is arranged below the forming system 7. The lower die assembly 4 includes a paper tray lower die 41 and a lower die washer 42 arranged on the paper tray lower die 41. The conveying track groove 5 abuts against the lower die washer 42, and the customized arc end of the conveying track groove 5 exactly matches the lower die washer 42; when pushing forward, the front limiting end of the lower die washer 42 is higher than the paper to perform front limiting on the paper to prevent the paper from being pushed out due to inertia and deviating from the molding position; when retracting backward, the paper first falls into the lower die washer 42, and the rear limiting end of the lower die washer 42 is lower than the pushing length adjusting plate 66, which can perform rear limiting on the paper to prevent the paper from being affected by the retracting pushing length adjusting plate.

[0062] The paper tray lower die 41 is arranged on the lower die fixing plate 43. A lower die support steel bar 44 is arranged at the lower end of the lower die fixing plate 43. The lower die fixing plate 43 is arranged on the frame 8 through a lower die pressing component. The lower die pressing components are symmetrically arranged in two. The lower die pressing component includes a lower die pressing plate 45. A lower die pressing screw 46 and a pressing adjusting screw 47 are arranged on the lower die pressing plate 45 to adjust the position of the paper tray lower die 41.

[0063] The conveying and pushing system 6 pushes a certain number of sheets sent by the paper output system to the forming system 7, performing the function of transferring the sheets. It includes a linear module and a pushing component fixedly connected to the slider 61 of the linear module. The linear module includes a third motor 62 and a ball screw 63. Guide rods 64 are arranged on both sides of the ball screw 63. The slider 61 is arranged on the ball screw 63 and the guide rods 64. The third motor 62 drives the ball screw 63 to rotate, thereby driving the slider 61 to move left and right.

[0064] The pushing component includes a pushing plate 65, a pushing length adjusting plate 66, and a pushing top block 67. The lower end of the pushing plate 65 is connected to the slider 61. The upper end of the pushing plate 65 is connected to the pushing length adjusting plate 66 through a washer. The pushing top block 67 is connected to the middle of the pushing length adjusting plate 66.

[0065] When the slider 61 is at the leftmost end, it is the initial position. At this time, the paper outlet of the paper output structure 3 is located at the front end of the pushing top block 67, and the paper can fall on the front end of the pushing top block 67. During the paper conveying process, when the paper output system sends enough sheets in the paper dropping area (the front end of the pushing top block 67), the third motor 62 starts to drive the ball screw 63 to rotate forward, and the slider 61 drives the pushing component forward to push the paper. When it reaches the position of the lower die washer 42 at the back, at this time, the paper freely falls from the end of the conveying track groove 5 to the pushing length adjusting plate 66, and then the third motor 62 reverses, and the slider 61 returns. The paper leaves the pushing length adjusting plate 66 and drops into the paper tray lower die 41, waiting for the subsequent molding process.

[0066] The forming system 7 includes an upper die assembly, an upper die fixed conversion plate 71, and a driving assembly. The upper die assembly includes a paper tray upper die 72, an upper die fixing seat 73, and an upper die support main shaft 74. The paper tray upper die 72 is connected to the upper die fixing seat 73. The upper die fixing seat 73 is connected to the upper die support main shaft 74. A spring is arranged outside the upper die support main shaft 74. The upper die support main shaft 74 is connected to the upper die fixed conversion plate 71.

[0067] The driving assembly includes a fourth motor 75 and a forming die adapter flange 76 connected to the output shaft of the fourth motor 75. The lower end of the forming die adapter flange 76 is installed on the upper die fixed conversion plate 71. The paper tray upper die 72 is compatibly installed through the slot-shaped mounting holes in the forming die adapter flange 76 and the upper die fixed conversion plate 71. The paper tray lower die 41 is supported by the lower die support steel bars 44, and lower die pressing plates 45 are symmetrically arranged at both ends. The lower die and the machine frame 8 are tightly fitted through the lower die pressing screws 46. Whether it is the installation scheme of the upper die or the lower die, it has strong die compatibility, can achieve multi-purpose with one machine, and greatly improves the production flexibility.

[0068] The fourth motor 75 is arranged on the positioning plate 77, and the positioning plate 77 is arranged on the frame 8 through the upright column 78. The conveying track groove 5 is arranged with a middle groove and a non-connected structure on the left and right. The conveying track groove 5 is connected to the upright column 78 through a connecting component. The connecting component includes a clamping shaft reversing block 51 and a conveying track support short shaft 52 and a conveying track support long shaft 53 vertically arranged on the clamping shaft reversing block 51. One end of the conveying track support short shaft 52 is connected to the conveying track groove 5, and the conveying track support long shaft 53 is connected to the upright column 78 through a clamping shaft fixing block 54. The conveying track support short shaft 52 can adjust the clamping position by loosening the clamping shaft reversing block 51, so that the left and right gaps between the conveying track grooves 5 change, and the width adjustment of the conveying track groove 5 is completed; and the conveying track support long shaft 53 can slide the conveying track groove 5 back and forth on a similar principle to complete the front and back position adjustment of the conveying track groove 5. Therefore, the installation of the conveying track groove 5 is very simple, and it has its own width adjustment and front and back position adjustment, and can adapt to different paper conveying requirements. In addition, the conveying track groove 5 is made of aluminum material, which can well avoid the static electricity problem and reduce the paper adhesion and dust adsorption problems.

[0069] Forming sliding shafts 79 are arranged on both sides of the output shaft of the fourth motor 75 on the positioning plate 77. The lower ends of the forming sliding shafts 79 are connected to the upper die fixing conversion plate 71, so as to keep the paper tray upper die 72 moving straight up and down and prevent deviation, thus affecting the buckling of the paper tray upper die 72 and the paper tray lower die 41.

[0070] After the paper is conveyed into the lower die washer 42, the upper fourth motor 75 (servo motor or linear motor) will extend downward. The bottom of its motor shaft is connected to the paper tray upper die. After extending until the paper tray upper die 72 and the paper tray lower die 41 are closed, the die core in the paper tray upper die 72 will eject the formed product, that is, the paper tray cup, and then the paper tray cup will slide into the storage frame along the channel in the frame 8. In this mold, both the upper and lower dies are heated. Among them, the upper die uses an inserted electric heating tube to heat the die blank, and the lower die uses an outer heating sleeve to heat the die blank to ensure the forming efficiency and forming accuracy.

[0071] A storage bin 81 is arranged at the lower end of the frame 8 where the lower die assembly 4 is located. The storage bin 81 is mainly arranged with a discharge port to facilitate the smoothly sliding of the molded products along the paper outlet sheet metal into the storage basket.
