Description

Folding paper cup and bowl making equipment Technical Field

[0001] The invention relates to equipment for making paper cups and bowls. Background Art

[0002] The molding and production of paper containers such as paper cups or paper bowls (collectively referred to as cups and bowls) requires the intervention of a turntable. There are relatively many workstations, and not only the cup bottom but also the cup mouth needs to be made. In addition, the production of both the cup bottom and the cup mouth requires multiple processes at different workstations, and the turntable carries the cup body to each workstation for corresponding molding and production. The large number of corresponding workstations of the turntable and the rotation method of the turntable lead to more complex structure, workstations and coordinated operation. It is necessary to additionally make the cup bottom and connect the cup body to form the cup body. In other molding processes, multiple turntables are required (the cup bottom and cup mouth are made on different turntables) for coordination and connection (the cup body is transferred and molded on multiple turntables), which makes the entire processing technology more complicated and less stable. Not only the barrel molding process is required, but also the cup bottom production work and the cup bottom and barrel connection process are required.

[0003] After the cup body is manufactured, it typically tapers or slopes throughout, opening at a certain angle. Rolling requires aligning this taper or slope, making it difficult and ineffective, prone to deformation and wrinkling, and placing high demands on the paper material. To address this, a vertical section was developed for the upper portion of the cup body to reduce the difficulty and material requirements, ensuring better rolling results and preventing deformation and wrinkling. However, the question of how to roll the tapered or sloped lower portion of the cup body, with the upper portion of the cup body being the vertical section to be rolled, remains unresolved.

[0004] During the production of cups and bowls, paper sheets need to be fed forward. Currently, the paper sheets are pushed forward by a paper support (the paper support has a channel for the paper pusher to move back and forth). A cylindrical body forming mold is located above the paper support. The paper sheets on the paper support are clamped to the cylindrical body forming mold, and the left and right overlaps of the paper sheets are bonded (using glue or ultrasound). We are currently developing a device that does not perform cylindrical body forming above the paper support. For example, the cup body (including the cylindrical body and cup base) can be directly formed in front of the paper support through upper and lower molds combined with stamping and folding. How to adapt the paper feeding requirements of this forming method to meet the requirements of not only paper feeding but also forming.

[0005] After paper containers such as paper cups and bowls are finished in a molding machine, they are discharged one by one. Typically, they are removed from the mold and placed into a pneumatic duct, where the wind propels them through the duct for collection. A machine has been developed that uses a robotic arm to grip and translate the finished cups and bowls individually. However, the subsequent configuration of a cup collection device to meet this demand remains a challenge, as does the method for collecting the discharged cups and bowls. Summary of the Invention

[0006] In view of the technical problems existing in the background technology, the technical problem solved by the present invention is to provide a paper cup and bowl production equipment with a new workstation structure layout.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions: folding paper cup bowl production equipment, including a paper feeding station, a cup body folding and forming station, a cup bowl rim dipping station, a cup bowl rim preheating station, a cup bowl rim rolling station and a collection station arranged in a straight line, characterized in that: the paper feeding station is equipped with a paper feeding device, the paper feeding device is connected with the cup body folding and forming station, the paper feeding device includes a paper supporting table, the paper supporting table has a paper feeding surface, the upper side of the paper feeding surface is provided with a heating component and / or a gluing component, the paper supporting table is also provided with a folding and forming blanking port, and the folding and forming blanking port is located in front of the heating component and / or the gluing component; the cup body folding The folding and forming station, cup rim oil dipping station, cup rim preheating station, cup rim curling station and adjacent stations in the collection station are connected by a translation robot. The cup body folding and forming station is equipped with a cup body folding and forming device. The cup body folding and forming device includes a matching forming upper mold and a forming lower mold. The forming upper mold is connected to the upper mold lifting drive device through transmission. The forming lower mold includes a forming mold cavity. The cup rim oil dipping station is equipped with an oil dipping device. The cup rim preheating station is equipped with a preheating device. The cup rim curling station is equipped with a curling device. The curling device includes a curling upper mold and a curling lower mold. The curling lower mold is arranged below the curling upper mold. The collection station is equipped with a cup receiving device.

[0008] Additional optimization or supplementary explanation may be provided on the above technical solutions, respectively, see the specific implementation methods.

[0009] The beneficial effects of the present invention are that it adopts a linear arrangement of workstation layout and a workstation combination method of a paper sheet feeding station, a cup body folding and forming station, a cup bowl rim dipping station, a cup bowl rim preheating station, a cup bowl rim curling station and a collection station, thereby optimizing the workstation combination structure and only requiring the folding and forming station (single station) to form paper cup bowls by folding and forming, thereby simplifying the structural layout, and can be relatively stable in a linear manner, avoiding the use of a complex rotary workstation connection method. Among them, the cups and bowls (semi-finished products and finished products) are transferred and connected by a longitudinal translation robot, and can be transferred in a linear direction to different workstations for corresponding processing and production. The linear operation has a relatively simple structure, relatively low cost and relatively high stability. It avoids the use of a complex structure with multiple turntable stations and multiple links. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] As shown in the figure, in an embodiment of this embodiment, the folding paper cup and bowl production equipment includes a paper sheet feeding station 33, a cup body folding and forming station 28, a cup bowl rim oiling station 29, a cup bowl rim preheating station 30, a cup bowl rim curling station 31, and a collection station 32. The paper sheet feeding station 33, the cup body folding and forming station 28, the cup bowl rim oiling station 29, the cup bowl rim preheating station 30, the cup bowl rim curling station 31, and the collection station 32 are arranged in a straight line and will be connected in sequence.

[0012] The paper sheet feeding station 33 is equipped with a paper sheet feeding device, which is connected to the cup body folding and forming station 28. Paper sheets are input at the paper sheet feeding station 33 and the paper sheet feeding device cooperates to input the paper sheets to the cup body folding and forming station 28.

[0013] The cup body folding and forming station 28, the cup bowl rim dipping station 29, the cup bowl rim preheating station 30, the cup bowl rim curling station 31 and the collection station 32 are connected by the translation robot 200, and the translation robot 200 cooperates to translate and transport the cup body in the production process forward between adjacent stations.

[0014] The cup body folding and forming station 28 is equipped with a cup body folding and forming device, and at the cup body folding and forming station 28 , the cup body folding and forming device folds the paper sheet into the cup body of the paper cup bowl.

[0015] The cup rim oiling station 29 is equipped with an oiling device, and the cup body is dipped in oil at the cup rim oiling station 29 by the oiling device, and the cup rim of the cup body can be rolled smoothly after being lubricated with oil.

[0016] The cup rim preheating station 30 is equipped with a preheating device. After the cup body is dipped in oil, the preheating device preheats the cup rim of the cup body in the cup rim preheating station 30. The preheated cup rim can be rolled more smoothly.

[0017] The cup bowl rim rolling station 31 is equipped with a rolling device. After preheating, the cup body is rolled by the rolling device at the cup bowl rim rolling station 31 to complete the paper cup bowl molding.

[0018] The collecting station 32 is equipped with a cup receiving device, and the cup body is finally output from the collecting station 32 and received and collected by the cup receiving device.

[0019] The heating component and / or gluing component in the paper feeding device can heat and / or gluing the paper to be bonded for subsequent folding and forming connection. The cup body folding and forming device configured at the cup body folding and forming station has a matching forming upper mold and forming lower mold for folding and forming the paper, and the cup bowl mouth rolling station is equipped with a rolling device with a rolling upper mold and a rolling lower mold for rolling the cup body.

[0020] The workstation layout is arranged linearly, with a combination of a paper sheet feeding station 33, a cup body folding and forming station 28, a cup rim oiling station 29, a cup rim preheating station 30, a cup rim curling station 31, and a collection station 32. This optimizes the workstation structure and only requires the folding and forming of paper cups and bowls at the folding and forming station (a single station). This simplifies the structural layout and allows for relatively stable linear operation, avoiding the complex rotary station connection method. The cups and bowls (semi-finished and finished products) are transferred and connected longitudinally by a translating robot arm. These cups and bowls can be moved linearly to different stations for processing and production. This linear operation is relatively simple, low-cost, and highly stable. This avoids the complex structure of a turntable with multiple stations and links.

[0021] Based on the above embodiments, the following optimization or further explanation may be performed.

[0022] As shown in the figure, the paper feeding device in the embodiment of this embodiment includes a paper support 35, which has a paper support and feed surface 36. The paper sheet is supported and slid on the paper support and feed surface 36. The paper support and feed surface 36 is also equipped with a paper pushing member 37, which cooperates to push the paper sheet forward as it slides on the paper support and feed surface 36. The paper pushing member 37 can be a straight pushing member (for linear pushing forward), such as a push head (for example, a one-way push head) or other mature paper pushing member, or multiple paper pushing members can be formed into a multi-stage pushing structure to push the paper sheet forward.

[0023] The upper side of the paper support and feeding surface 36 is also equipped with a heating component 38 (such as a hot air blowing device) and / or a gluing component (such as a glue gun device). The heating component 38 can heat the coating layer at the paper sheet to be bonded so that it can be bonded during subsequent molding and / or the gluing component can heat the glue (such as dispensing glue, etc.) at the paper sheet to be bonded so that it can be bonded during subsequent (folding) molding.

[0024] The paper support table 35 is also provided with a folding and forming discharge port 39. The paper pieces on the paper supporting feeding surface 36 of the paper support table 35 will go down from the folding and forming discharge port 39 for subsequent folding and forming. The cup body folding and forming device will be arranged at the folding and forming discharge port 39. The folding and forming discharge port 39 is opened on the paper supporting feeding surface 36 so that the paper pieces can be pushed and slid forward to the folding and forming discharge port 39; the left side, right side and rear side of the folding and forming discharge port 39 are respectively connected with the paper supporting feeding surface 36, that is, the paper supporting feeding surface 36 has corresponding parts connected on the left side, right side and rear side of the folding and forming discharge port 39. When the paper pieces are pushed and slid forward, they can smoothly and stably reach the folding and forming discharge port 39 and wait to go down (they will enter the cup body folding and forming device of the cup body folding and forming station 28), and the cup body folding and forming station 28 will be connected at the folding and forming discharge port 39.

[0025] The folding and forming discharge port 39 is located on the front side (output side) of the heating component 38 and / or the gluing component, that is, when the paper sheet is pushed and slid forward, it first passes through the heating component 38 and / or the gluing component to be processed at the adhesion area, and then is pushed to the folding and forming discharge port 39.

[0026] Principle and effect: The paper feeding device can push the paper forward in a straight line, and preheat or glue the part of the paper to be bonded (i.e., pretreatment) during the pushing process so that it can be smoothly bonded and fixed during subsequent folding and forming. It combines paper feeding with pretreatment, and directly transports the pretreated paper to the folding and forming discharge port 39 to wait for subsequent folding and forming. It can not only cooperate with efficient paper feeding to the folding and forming discharge port 39, but also cooperate with folding and forming for pretreatment, thereby meeting the needs of folding paper into cups and bowls.

[0027] For example, the left and right sides of the folding and forming feed opening 39 are respectively provided with a paper pressing plate 40, and a paper passing matching gap is left between the paper pressing plate 40 and the paper supporting and feeding surface 36 below. On the left and right sides of the folding and forming feed opening 39, the paper pressing plate 40 can press the left and right edges of the paper sheet onto the paper supporting and feeding surface 36. The left and right edges of the paper sheet will be located in the paper passing matching gap and advance, ensuring that the paper sheet advances smoothly and stably through the folding and forming feed opening 39, so that the paper sheet can cover the folding and forming feed opening 39, and when the subsequent paper sheet goes down to be folded and formed, the paper passing matching gap can also protect the left and right edges of the paper sheet to allow the paper sheet to go down stably. The inner edge of the paper pressing plate 40 can be set to an arc edge to better adapt to the arc shape on both sides of the paper sheet, avoiding warping and bending when the paper sheet goes down.

[0028] The paper press 40 is connected to the paper support 35, making installation relatively easy. A gap adjustment block 42 is also connected between the paper press 40 and the paper support 35. By replacing the gap adjustment block 42 with different thicknesses, the paper feed gap can be adjusted, thereby adjusting the pressure applied to the paper during feeding. The input side of the paper press 40 can be equipped with an upturned guide flare to facilitate paper feeding.

[0029] The left and right sides of the paper support and feed surface 36 are also equipped with paper side limit gauges 43. The paper side limit gauges 43 can limit the left and right sides of the paper sheet, so that the paper sheet does not shift when it is pushed forward on the paper support and feed surface 36. The paper side limit gauges 43 on the left and right sides of the folding and forming discharge port 39 are located between the paper support and feed surface 36 and the paper pressing plate 40, so that the left and right sides of the paper sheet advancing at the folding and forming discharge port 39 can also be limited.

[0030] The paper support platform 35 is also provided with a feed opening adjustment and replacement frame 44. The paper feeding surface 36 includes the upper side surface of the feed opening adjustment and replacement frame 44. The upper side surface of the feed opening adjustment and replacement frame 44 will also serve as a part of the paper feeding surface 36. A plurality of plates (such as a heat dissipation plate with a heat dissipation structure (such as a heat dissipation hole) can be provided on the paper support platform 35. The paper feeding surface 36 is formed by a combination of structures such as a heat dissipation plate and a frame. The inner edge of the feed opening adjustment and replacement frame 44 is the edge of the folding and forming feed opening 39. The feed opening adjustment and replacement frames 44 of different specifications and sizes are replaced to adapt to paper sheets of different sizes and cooperate with folding and forming.

[0031] The front side of the folding and forming opening 39 is also equipped with paper feed limiting components 45 (such as paper feed limiting blocks). The paper feed limiting components 45 are arranged on the left and right sides of the folding and forming opening 39. The paper feed limiting components 45 (such as paper feed limiting blocks) can be adjusted to accommodate paper sheets of different sizes and shapes.

[0032] In addition, the front side of the folding and forming discharge port 39 is also equipped with an auxiliary paper support component (such as an auxiliary paper support platform 35), which can support the front side of the paper sheet, making the paper sheet more stable when staying and going down at the folding and forming discharge port 39. The auxiliary paper support component is installed on the support frame.

[0033] As an additional optimization, the upper side of the paper supporting and feeding surface 36 is also provided with a paper pressing mechanism 46, which can cooperate to press the paper sheet on the paper supporting and feeding surface 36 to prevent the paper sheet from shifting when being pushed forward. By pressing the paper, the paper sheet will not be lifted up to prevent the paper pushing component 37 from pushing in vain. The paper pressing mechanism 46 can also cooperate with the paper pressing to ensure that the one-way paper pushing component 37 (including a paper pushing block with a spring swing on the paper pushing seat) can be smoothly retracted without causing the paper to shift. The paper pressing mechanism 46 includes a paper pressing rod 47 and a paper pressing chain 48. The paper pressing rod 47 is located on the left and right sides of the paper pressing chain 48. The front and rear ends of the paper pressing chain 48 are respectively connected to the mounting base 49 for setting and fixing. The paper pressing rod 47 can press the paper to prevent the paper from tilting up, and can also press the paper to make it move smoothly. However, it is difficult to achieve compaction and stabilization by relying solely on the paper pressing rod 47. The paper pressing chain 48 is used to compact and stabilize the paper in the middle position. The paper pressing chain 48 is relatively soft and can be deformed so that it can fit and compact the paper, making it difficult for the paper to deviate. The cost of combining the paper pressing rod 47 and the paper pressing chain 48 is relatively low. A gantry frame can be set on the paper support 35 for the mounting base 49, the paper pressing rod 47, the heating component 38 and / or the gluing component to be suspended.

[0034] In addition, there are many ways to feed paper sheets to the paper support 35. For example, single paper sheets are stacked in a material warehouse, and a suction nozzle is used to suck them down from the bottom of the material warehouse to the paper support 35 one by one, and then pushed forward by the paper pushing component 37. Other feeding methods can also be used.

[0035] As shown in the figure, the translation robot 200 in the embodiment of this embodiment includes four groups of cup and bowl clamping assemblies 1, and the cup and bowl clamping assemblies 1 include a left clamping part 2 and a right clamping part 3 that are paired on the left and right. The left clamping part 2 and the right clamping part 3 in each group of cup and bowl clamping assemblies 1 will clamp the cup and bowl when they are close together, and release the cup and bowl when they are separated.

[0036] The left clamping parts 2 in each group of cup and bowl clamping assemblies 1 are respectively arranged on the left bracket 4, and the left bracket 4 is connected to the first movable assembly 5. The left bracket 4 moves together with the first movable assembly 5. The first movable assembly 5 includes a first transverse movement seat 6 (capable of transverse movement) and a first longitudinal movement seat 7 (capable of longitudinal movement) that are connected to each other, so that the first movable assembly 5 can move transversely and longitudinally. The left bracket 4 will move transversely (left and right) and longitudinally (forward and backward) with the first movable assembly 5.

[0037] The right clamping parts 3 in each group of cup and bowl clamping assemblies 1 are respectively arranged on the right bracket 8, and the right bracket 8 is connected to the second movable assembly 9. The right bracket 8 moves together with the second movable assembly 9. The second movable assembly 9 includes a second transverse displacement seat 10 (capable of transverse displacement) and a second longitudinal displacement seat 11 (capable of longitudinal displacement) connected to each other, so that the second movable assembly 9 can move transversely and longitudinally, and the right bracket 8 will move transversely (left and right) and longitudinally (forward and backward) with the second movable assembly 9.

[0038] Principle and Effect: The left and right clamping components 2 and 3 in each set of cup and bowl clamping assemblies 1 cooperate to clamp the corresponding cups and bowls and move them longitudinally, thereby transferring them in a straight line for processing at different workstations. This linear operation, combined with a multi-station stop mechanism, results in a relatively simple structure, low cost, and high stability. The four sets of cup and bowl clamping assemblies 1 operate synchronously and efficiently, avoiding the complex structure of a turntable with multiple stations and links.

[0039] For example, the first transverse movement seat 6 is connected to the first longitudinal movement seat 7, that is, the first transverse movement seat 6 moves transversely on the first longitudinal movement seat 7, and the first transverse movement seat 6 can also move longitudinally with the first longitudinal movement seat 7; the second transverse movement seat 10 is connected to the second longitudinal movement seat 11, that is, the second transverse movement seat 10 moves transversely on the second longitudinal movement seat 11, and the second transverse movement seat 10 can also move longitudinally with the second longitudinal movement seat 11, resulting in a relatively compact structure. Alternatively, the first longitudinal movement seat 7 is connected to the first transverse movement seat 6, and the second longitudinal movement seat 11 is connected to the second transverse movement seat 10.

[0040] For another example, the first transverse movement seat 6 is equipped with a first transverse movement guide rail 12, and the first transverse movement seat 6 can be guided to move transversely by the first transverse movement guide rail 12; the first longitudinal movement seat 7 is equipped with a first longitudinal movement guide rail 13, and the first longitudinal movement seat 7 is guided to move longitudinally by the first longitudinal movement guide rail 13, and the movement is more stable through the guided cooperation; the second transverse movement seat 10 is equipped with a second transverse movement guide rail 14, and the second transverse movement seat 10 can be guided to move transversely by the second transverse movement guide rail 14; the second longitudinal movement seat 11 is equipped with a second longitudinal movement guide rail 15, and the second longitudinal movement seat 11 is guided to move longitudinally by the second longitudinal movement guide rail 15, and the movement is more stable.

[0041] For example, a first transverse guide rail 12 is arranged on the first longitudinal movement seat 7, the first transverse movement seat 6 is connected to the first transverse guide rail 12, the first longitudinal movement seat 7 is connected to the first longitudinal movement guide rail 13, and the first longitudinal movement guide rail 13 is connected and installed on the left support frame 16 for support; a second transverse guide rail 14 is arranged on the second longitudinal movement seat 11, the second transverse movement seat 10 is connected to the second transverse guide rail 14, the second longitudinal movement seat 11 is connected to the second longitudinal movement guide rail 15, and the second longitudinal movement guide rail 15 is connected and installed on the right support frame 17 for support.

[0042] For example, the first transverse shift seat 6 is connected to a first transverse drive, and the second transverse shift seat 10 is connected to a second transverse drive; the first longitudinal shift seat 7 is connected to a first longitudinal drive, and the second longitudinal shift seat 11 is connected to a second longitudinal drive. Transverse or longitudinal movement is driven by the corresponding drive, which can be a variety of drive types, such as motors or cylinders.

[0043] For another example, the first transverse shift seat 6 is connected to a first transverse shift drive cylinder 18 or a motor, and the first transverse shift drive cylinder 18 or the motor is provided on the first longitudinal shift seat 7. The first transverse shift drive cylinder 18 or the motor drives the first transverse shift seat 6 to transversely shift on the first longitudinal shift seat 7.

[0044] The second lateral movement seat 10 is connected to a second lateral movement drive cylinder 19 or a motor, which is arranged on the second longitudinal movement seat 11. The second lateral movement drive cylinder 19 or the motor drives the second lateral movement seat 10 to move transversely on the second longitudinal movement seat 11.

[0045] The first longitudinal shift seat 7 is connected to a first synchronous belt 20, which is wound around a first pulley set 21. The first pulley set 21 includes a first input pulley 22 and a corresponding driven pulley. The first input pulley 22 is connected to the first synchronous belt 20, and the first synchronous belt 20 is wound around the first pulley set 21. The first synchronous belt 20 drives the first longitudinal shift seat 7 to move longitudinally.

[0046] The second longitudinal shift seat 11 is connected to a second synchronous belt 23, which is wound around a second pulley assembly. The second pulley assembly includes a second input pulley and a corresponding driven pulley. The second input pulley is connected to the second synchronous belt 23, and the second synchronous belt 23 is wound around the second pulley assembly. The second synchronous belt 23 drives the second longitudinal shift seat 11 to move longitudinally.

[0047] The first input wheel 22 is connected to the first drive motor, and the second input wheel is connected to the second drive motor, and they are driven by the drive motors respectively, or the first input wheel 22 and the second input wheel are connected to the synchronous shaft 24, and the synchronous shaft 24 is connected to the synchronous drive motor 25. The synchronous drive motor 25 drives the first input wheel 22 and the second input wheel through the synchronous shaft 24, thereby synchronously driving the first synchronous belt 20 and the second synchronous belt 23 to revolve, so that the first longitudinal movement seat 7 and the second longitudinal movement seat 11 are longitudinally moved synchronously.

[0048] The left clamping component 2 and the right clamping component 3 include a mounting plate 26 and a clamping seat 27 provided on the mounting plate. Different specifications, sizes and shapes of the clamping seat 27 can be replaced according to needs (such as the shape and size of cups and bowls, etc.), and multiple clamping seats 27 can be provided.

[0049] Between the left clamping part 2 and the right clamping part 3, the cup body folding and forming station 28, the cup bowl rim oil dipping station 29, the cup bowl rim preheating station 30, the cup bowl rim curling station 31 and the collection station 32 are arranged in sequence along the longitudinal direction, that is, the corresponding stations are arranged in a straight line along the longitudinal direction. Then, the four groups of cup and bowl clamping assemblies 1 can cooperate to efficiently transfer the cups and bowls along the stations, and cooperate with the five-station stop structure. The first group of cup and bowl clamping assemblies 1 is connected between the cup body folding and forming station 28 and the cup bowl rim oil dipping station, the second group of cup and bowl clamping assemblies 1 is connected between the cup bowl rim oil dipping station and the cup bowl rim preheating station 30; the third group of cup and bowl clamping assemblies 1 is connected between the cup bowl rim preheating station 30 and the cup bowl rim curling station 31; the fourth group of cup and bowl clamping assemblies 1 is connected between the cup bowl rim curling station 31 and the collection station 32.

[0050] The first moving assembly 5 and the second moving assembly 9 operate synchronously, that is, the first moving assembly 5 and the second moving assembly 9 move laterally (transversely) and longitudinally (longitudinally) synchronously.

[0051] As shown in the figure, the paper cup bowl body folding and forming device in the embodiment of this embodiment includes a forming upper mold 65 and a forming lower mold 66 that match each other. The forming upper mold 65 is transmission-connected to the upper mold lifting drive device, and the forming upper mold 65 is driven to rise and fall as a whole by the upper mold lifting drive device. The upper mold lifting drive device can use a motor or a cylinder as the power. The forming lower mold 66 is arranged below the forming upper mold 65. When the forming upper mold 65 descends, it will cooperate with the forming lower mold 66 to fold the paper sheet to form the paper cup bowl body.

[0052] The present embodiment will also adopt the following optimization, which can vertically arrange the portion of the cup body to be rolled after the paper sheet is folded (almost in an upright state, which can be regarded as a vertical state, with relatively no slope or taper).

[0053] The upper molding die 65 includes a first molding surface 68 and a second molding surface 69 . The first molding surface 68 is connected to the lower portion of the second molding surface 69 . The first molding surface 68 is larger at the top and smaller at the bottom and has a taper and / or slope. The second molding surface 69 is vertically arranged.

[0054] The lower molding die 66 includes a molding cavity 70, and the molding cavity 70 includes a third molding surface 71 and a fourth molding surface 72. The third molding surface 71 is connected to the bottom of the fourth molding surface 72. The third molding surface 71 is larger at the top and smaller at the bottom, and has a taper and / or slope. The third molding surface 71 corresponds to and matches the first molding surface 68. The fourth molding surface 72 is vertically arranged, and the fourth molding surface 72 corresponds to and matches the second molding surface 69.

[0055] For example, when making square cups and bowls, the four side surfaces are inclined surfaces with slopes, and the four side surfaces (inclined surfaces) are connected by tapered curved surfaces. The bottom surface is usually flat, and additional concave and convex embossing can also be added to the flat surface.

[0056] Principle and effect: After the paper sheet between the forming upper mold 65 and the forming lower mold 66 (usually the paper sheet is pre-die-cut and indented to facilitate smooth folding and forming) is in place, the forming upper mold 65 descends and presses the paper sheet into the forming mold cavity 70 of the forming lower mold 66. The entire paper sheet will be folded and formed into a paper cup bowl body. The first forming surface 68 and the third forming surface 71 cooperate with each other to fold out the main part of the paper cup bowl body, while the second forming surface 69 and the fourth forming surface 72 cooperate with each other to fold out the part to be rolled on the upper side of the main part of the paper cup bowl body. The second forming surface 69 and the fourth forming surface 72 are respectively arranged vertically, so that the paper in the part to be rolled is in a vertical state (almost in an upright state, which can be regarded as a vertical state, with relatively no slope or taper). The paper in the part to be rolled in a vertical state is convenient for later rolling, the rolling difficulty is relatively reduced, the rolling effect is relatively good, and it is not easy to deform or wrinkle, and the requirements for paper materials are relatively low.

[0057] For example, the upper entrance of the forming cavity 70 is equipped with a first roller-guided pre-folding device 73 and a second roller-guided pre-folding device 74. The first roller-guided pre-folding device 73 and the second roller-guided pre-folding device 74 are staggered, with one positioned above the other. As shown in the figure, the first roller-guided pre-folding device 73 is positioned above the second roller-guided pre-folding device 74. The first roller-guided pre-folding device 73 includes a left and right paper guide roller assembly 75 and 76, which are positioned opposite each other. The second roller-guided pre-folding device 74 includes a front and rear paper guide roller assembly 77 and 78, which are positioned opposite each other. As the paper sheet is fed downward into the forming cavity 70, the corresponding paper guide roller assemblies coordinate with the paper sheet to perform pre-folding. The staggered arrangement allows for sequential pre-folding of the left and right edges and the front and rear edges of the paper sheet, ensuring smooth and stable forming upon entry into the forming cavity 70. This avoids problems such as unstable and distorted forming that may occur if the paper sheet enters the forming cavity 70 directly.

[0058] The left paper guide roller assembly 75, the right paper guide roller assembly 76, the front paper guide roller assembly 77 and the rear paper guide roller assembly 78 are respectively equipped with corresponding roller mounting sliders, which are respectively configured on the slide rails. The roller mounting sliders can move on the corresponding slide rails. The roller mounting sliders are also connected with a paper guide pre-tightening buffer spring 81. The paper guide pre-tightening buffer spring 81 acts on the roller mounting slider, so that the left paper guide roller assembly 75, the right paper guide roller assembly 76, the front paper guide roller assembly 77 and the rear paper guide roller assembly 78 have pre-tightening force respectively. When the paper is pre-folded, the paper sheet can be pre-tightened as much as possible against the first molding surface 68 and the second molding surface 69 of the forming upper mold 65, and the paper pre-folding effect is better.

[0059] The left paper guide roller assembly 75, the right paper guide roller assembly 76, the front paper guide roller assembly 77, and the rear paper guide roller assembly 78 each include a roller and / or a wheel. Furthermore, the left and right paper guide roller assemblies 75 and 76 may each have rolling flanges at their respective ends, and / or the front and rear paper guide roller assemblies 77 and 78 may each have rolling flanges at their respective ends. These rolling flanges can bend the left and right and / or front and rear wings of the paper sheet inward, facilitating transition and even forming a tapered surface. This allows the pre-folded portion of the paper sheet to be more easily folded over and overlapped with the previously pre-folded portion.

[0060] The fourth forming surface 72 is provided with a notch 82, within which is located an overlapping flat push block 83. This overlapping flat push block 83 is connected to a flat push drive 84 (e.g., comprising a cylinder or motor). This flat push drive 84 drives the overlapping flat push block 83 to apply pressure to the overlapping joint between the fourth forming surface 72 and the third forming surface 71, ensuring a secure connection and avoiding the problem of a loose joint resulting from a vertical arrangement of the fourth forming surface 72 and the third forming surface 71. Typically, the notch 82 and overlapping flat push block 83 are located at the four corners of the paper cup body, i.e., at the overlapping corners of the left and right sides and the front and back sides of the paper sheet. The center area of ​​the paper sheet forms the bottom of the paper cup.

[0061] The upper forming mold 65 is provided with a telescopic ejector module 85, which is arranged at the bottom of the upper forming mold 65; the telescopic ejector module 85 is connected to a ejection cylinder 86 or a ejection spring, which is installed on the upper forming mold 65. When the telescopic ejector module 85 is extended by the ejection cylinder 86 or the ejection spring, it will cooperate to eject the paper cup body on the upper forming mold 65 from the mold.

[0062] The first molding surface 68 of the upper mold 65 is further provided with air holes 87. Air blown through the air holes 87 not only loosens the cup body to facilitate demolding, but also facilitates smooth demolding, avoiding unstable demolding caused by forced ejection or downward suction, or even problems such as the cup body being misplaced after demolding and subsequent difficulty in operation, but also helps to push the cup body downward.

[0063] The molding cavity 70 is also provided with a lifting support plate 89, and the lifting support plate 89 is equipped with a return spring or a return cylinder 90. After the lifting support plate 89 rises and returns, it can cooperate with the descending molding upper mold 65 to clamp the paper sheet and send it downward to ensure that the paper position is accurate and does not shift. During the downward sending process, the return spring or the return cylinder 90 is pressurized; after the molding is completed, when the molding upper mold 65 rises, the lifting support plate 89 rises and returns under the action of the return spring or the return cylinder 90; the bottom of the molding cavity 70 is also provided with a support plate avoidance port 91, which matches the lifting support plate 89, and the support plate avoidance port 91 provides an avoidance position for the lifting support plate 89.

[0064] Furthermore, the lifting support 89 is equipped with a paper suction nozzle, which is used to suck the paper and the bottom of the folded paper cup. When the paper is located between the upper and lower forming dies, the lifting support 89 supports the paper, ensuring that it is placed in place. The suction nozzle also helps to hold the paper in place and prevent it from shifting. After the paper cup is folded and formed, it also helps to facilitate demolding. The suction nozzle is connected to a hollow guide rod 93, which is attached to the bottom of the lifting support 89 and slidably connected to a guide sleeve 94. The hollow guide rod 93 not only guides the lifting support 89 but also connects to the suction nozzle for air supply. Alternatively, the top surface of the lifting support 89 and the bottom surface of the upper forming die 65 can be provided with matching indentation forming portions to enhance the strength and pattern of the cup bottom.

[0065] The upper forming die 65 and / or the lower forming die 66 are also connected to a heating element 95 (such as a heating wire or heating tube rod). Heating improves the folding and forming effect and strengthens the shape. The lower forming die 66 is also provided with a vent hole, which communicates with the forming cavity 70 and is connected to the third forming surface 71. This allows air to be exhausted when the paper sheet is pressed against the forming cavity 70 of the lower forming die 66, particularly the third forming surface 71, to prevent residual air from causing bulging and folding of the paper sheet.

[0066] As shown in the figure, in the embodiment of this embodiment, the rolling device includes an upper rolling die 96 and a lower rolling die 97, and the lower rolling die 97 is arranged below the upper rolling die 96.

[0067] In this embodiment, the following optimization will be adopted, which can make the paper to be rolled almost in a vertical state (can be regarded as a vertical state, relatively without inclination or taper) and form a curled edge by rolling, which is convenient for rolling, the difficulty of rolling is relatively reduced, the rolling effect is relatively good, it is not easy to deform or wrinkle, and the requirements for paper materials are relatively low.

[0068] The upper mold 96 for curling includes a lifting seat 98, an upper mold core 99 and an upper curling disk 100. The upper curling disk 100 and the upper mold core 99 are arranged on the lifting seat 98. The upper curling disk 100 and the upper mold core 99 can be lifted and lowered along with the lifting seat 98. In addition, a telescopic buffer spring 101 (a gas spring can be optionally used) is connected between the upper mold core 99 and the lifting seat 98, so that the upper mold core 99 can be further lifted and retracted on the lifting seat 98.

[0069] The upper curling disc 100 is provided with a first channel 102 , and a first curling groove 103 is provided on the lower end surface of the upper curling disc 100 . The first curling groove 103 is arranged at (surrounding) the edge of the lower port of the first channel 102 , and is used to curl the cup body.

[0070] A first vertical outer wall area 104 is provided on the outer ring side wall of the upper mold core 99, and the first channel 102 is sleeved outside the first vertical outer wall area 104. The first vertical outer wall area 104 matches the first channel 102, that is, the upper mold core 99 can extend and retract in the first channel 102, and the first vertical outer wall area 104 of the upper mold core 99 can slide in the first channel 102; the upper mold core 99 also has a cup cavity matching outer wall area 105, and the cup cavity matching outer wall area 105 is connected to the bottom of the first vertical outer wall area 104, and the cup cavity matching outer wall area 105 matches the main part of the cup body. The cup cavity matching outer wall area 105 of the upper mold core 99 can be supported in the main part of the cup body (that is, the cup cavity).

[0071] The lower mold 97 for curling includes a lower mold core 106 and a lower curling plate 107. The lower mold core 106 is provided with a cup body matching cavity 108. The cup body matching cavity 108 cooperates with the cup cavity matching outer wall area 105 of the upper mold core 99. The upper mold core 99 pushes the paper sheet downward into the cup body matching cavity 108 of the lower mold core 106. The cup cavity matching outer wall area 105 of the upper mold core 99 cooperates with the cup body matching cavity 108 of the lower mold core 106 to clamp the cup body.

[0072] The outer ring side wall of the lower mold core 106 has a second vertical outer wall area 109 .

[0073] A second channel 110 is provided on the lower curling disk 107, and the second channel 110 is sleeved outside the second vertical outer wall area 109. The second vertical outer wall area 109 matches the second channel 110, that is, the lower curling disk 107 can be sleeved outside the lower mold core 106 and raised and lowered; the upper end surface of the lower curling disk 107 is provided with a second curling groove 111, and the second curling groove 111 is arranged at (surrounding) the edge of the upper port of the second channel 110, and the second curling groove 111 is used to curl the cup body.

[0074] A paper clamping gap 112 is left between the first vertical outer wall area 104 and the channel wall of the second channel 110 to match the paper to be rolled (i.e., the paper 130 at the to-be-rolled portion on the upper side of the main body of the cup). The paper clamping gap 112 can clamp the paper at the to-be-rolled portion of the cup body in a relatively stable position, so that this part of the paper is leaning against the outside of the first vertical outer wall area 104 and is almost in a vertical state.

[0075] The lower curling disc 107 is also connected to a disc lifting drive device 113 (such as a power drive including a motor or a cylinder), and the disc lifting drive device 113 drives the lower curling disc 107 to perform a lifting action to cooperate with the curling.

[0076] Principle and effect: The formed cup body is placed between the upper roll mold 96 and the lower roll mold 97. The lifting seat 98 of the upper roll mold 96 descends, and the upper mold core 99 and the upper curling disk 100 descend together. The upper mold core 99 pushes the cup body downward into the cup body matching cavity 108 of the lower mold core 106. The first vertical outer wall area 104 on the upper mold core 99 cooperates with the cup body matching cavity 108 to clamp the cup body. At this time, the part of the cup body to be rolled is located in the paper-to-be-rolled gap 112 between the first vertical outer wall area 104 and the channel wall of the second channel 110, so that the paper to be rolled is almost in a vertical state (can be regarded as a vertical state). Then the lifting seat 98 continues to descend. At this time, the upper mold core 99 has When the paper is in place (the telescopic buffer spring 101 is deformed), the lifting seat 98 continues to descend, which will drive the upper curling disc 100 to continue to descend. The upper curling disc 100 and the lower curling disc 107 descend together, and the first curling groove 103 and the second curling groove 111 are arranged in coordination with each other. The first curling groove 103 and the second curling groove 111 cooperate to curl together, and the curling (i.e., the curling edge) is enclosed between the first curling groove 103 and the second curling groove 111; the paper to be curled is almost in a vertical state (can be regarded as a vertical state, relatively without inclination or taper) and is curled to form a curled edge, which is convenient for curling, and the difficulty of curling is relatively reduced, the curling effect is relatively good, and it is not easy to deform or wrinkle, and the requirements for paper materials are relatively low. After the curling is completed, the lifting seat 98 rises, the upper curling disk 100 rises and separates from the lower curling disk 107, and then the telescopic buffer spring 101 returns to its position, and the upper mold core 99 also starts to rise with the lifting seat 98, and then the upper curling disk 100 starts to rise under the drive of the disk body lifting drive device 113.

[0077] For example, the first channel 102 comprises a vertical straight tube, and the second channel 110 comprises a vertical straight tube. Alternatively, the vertical straight tube of the second channel 110 may further comprise a curling guide micro-flare 114 for guiding the curling, so that the curling can be guided into the first curling groove 103 above, with the flare angle within 3 degrees.

[0078] The lifting seat 98 is connected to the rolling mouth lifting drive device (such as a power source including a cylinder, an electric cylinder, or a motor), and the lifting seat 98 is driven by the rolling mouth lifting drive device to move up and down. The lower mold core 106 is arranged on the fixed seat 116, and the disc lifting drive device 113 is connected to the fixed seat 116.

[0079] The cup body matching cavity 108 is also provided with a lifting base 117, and the lifting base 117 is equipped with a lifting reset spring or a lifting reset cylinder 118; the bottom of the cup body matching cavity 108 is also provided with a base avoidance opening 119, and the base avoidance opening 119 matches the lifting base 117.

[0080] After the lifting base 117 rises and resets, it can cooperate with the descending curling upper mold 96 to clamp the cup body and send it downward to ensure that the cup body is accurately positioned and does not shift. During the downward sending process, the lifting reset spring or the lifting reset cylinder 118 is pressurized; after the curling is completed, when the curling upper mold 96 rises, the lifting base 117 rises and resets under the action of the lifting reset spring or the lifting reset cylinder 118; the bottom of the cup body matching cavity 108 is also provided with a base avoidance opening 119, which matches the lifting base 117, and the base avoidance opening 119 provides an avoidance position for the lifting base 117.

[0081] The lifting base 117 is also equipped with a suction cup air nozzle 120, which is connected to a hollow guide column 121. The hollow guide column 121 is connected to the lower side of the lifting base 117. The hollow guide column 121 is slidably connected with the guide sleeve 122 (the lifting base 117 should also be blocked when it descends).

[0082] In addition, the lifting base 117 is also equipped with a suction cup air nozzle 120, which is used to suck the cup body. When the cup body is located between the upper rolling mold 96 and the lower rolling mold 97, the lifting base 117 supports the cup body so that the cup body is placed in place, and the suction cup air nozzle 120 can also cooperate to suck the cup body into place without shifting, and can also cooperate to suck the cup body after the rolling is completed to facilitate demolding; the suction cup air nozzle 120 is connected to the hollow guide column 121, and the hollow guide column 121 is connected to the lower side of the lifting base 117. The hollow guide column 121 is slidably connected with the guide sleeve 122. The hollow guide column 121 not only plays the role of lifting and guiding the lifting base 117, but also can be connected to the suction cup air nozzle 120 to supply air.

[0083] The upper mold core 99 is provided with a telescopic demolding member 123, which is located at the bottom of the upper mold core 99. The telescopic demolding member 123 is connected to a demolding cylinder 86 or a demolding spring, which is mounted on the upper mold core 99. When the telescopic demolding member 123 is extended by the demolding cylinder 86 or the demolding spring, it ejects the paper cup body from the upper mold core 99.

[0084] The upper mold core 99 is further provided with a small air blowing port 124. The air blowing port 124 not only loosens the paper cup body to facilitate demoulding, but also facilitates smooth demoulding, avoiding unstable demoulding caused by forced ejection or downward suction, and even problems such as the paper cup body being misplaced after demoulding and subsequent difficulty in operation, but also helps to blow the paper cup body downward.

[0085] The upper curling disc 100 and / or the lower curling disc 107 are also connected to a heater 125 (such as a heating wire or a heating tube rod, etc.). After heating, the curling effect is better and the shaping is more firm.

[0086] There are many ways to receive cups. You can directly use a conveyor belt to output one by one or use a lifting material receiving platform to receive cups, etc. In this embodiment, the cup receiving device adopts a cup receiving and stacking device.

[0087] The cup receiving, collecting and stacking device includes a cup receiving and dropping channel 51, which is vertically arranged so that cups and bowls can fall in the cup receiving and dropping channel 51. The upper end of the cup receiving and dropping channel 51 is a translation cup feeding position 52, so that cups and bowls can be input into position from the translation cup feeding position 52. After being input into position, the cups and bowls will fall into the cup receiving and dropping channel 51 for cup receiving, collecting and stacking.

[0088] The upper end of the cup receiving and dropping channel 51 is also equipped with a lifting and connecting cup feeding air nozzle 53. The lifting and connecting cup feeding air nozzle 53 descends to cooperate with the cup bowl in place at the translation cup feeding position 52. After sucking the cup bowl, the lifting and connecting cup feeding air nozzle 53 descends again to cooperate with the cup bowl to be sucked down into the cup receiving and dropping channel 51 for falling. The cup feeding is more efficient and stable through connection. After the cup bowl at the translation cup feeding position 52 is sucked by the lifting and connecting cup feeding air nozzle 53, the device that sends the cup bowl to the translation cup feeding position 52 (such as a translation robot) can retreat to process the next cup bowl, and the cup bowl is sucked and sent downward into the cup receiving and dropping channel 51 more stably.

[0089] The cup receiving and dropping channel 51 is also equipped with a lifting cup receiving and holding component 54 (such as a lifting cup receiving and holding plate). The lifting cup connecting and feeding air nozzle 53 is opposite to the lifting cup receiving and holding component 54 up and down. The lifting cup connecting and feeding air nozzle 53 sucks the cups and bowls and sends them down into the cup receiving and dropping channel 51 to be received by the lifting cup receiving and holding component 54. The cups and bowls are stacked one by one on the lifting cup receiving and holding component 54. The lifting cup receiving and holding component 54 can also sort the stacked cups and bowls during the repeated lifting and lowering process (shaking up and down), and the lifting cup receiving and holding component 54 gradually descends during the lifting process so that the stacked cups and bowls form a set height, and then the lifting cup receiving and holding component 54 will descend into place (i.e., land).

[0090] The bottom of the cup receiving and dropping channel 51 is also provided with a cup receiving component 55 in a lowered position. The cup receiving component 55 in the lowered position has an escape opening 56 for the lifting and lowering of the cup receiving and holding component 54. When the lifting and holding component 54 drops into place, it will enter the escape opening 56. The stacked cups and bowls on the lifting and holding component 54 will be caught by the cup receiving component 55 in the lowered position, completing the cup receiving and stacking. At this time, the cups and bowls on the cup receiving component 55 in the lowered position can be taken away, pushed away or transported away by a conveyor belt, and the lifting and holding component 54 will rise again to cooperate in catching the cups and bowls.

[0091] Principle and Effect: The cup receiving, stacking, and stacking device can collect and stack cups and bowls. It accommodates cups and bowls that are being transferred (e.g., by a robot) and efficiently receives cups through the lifting and connecting cup delivery nozzle 53 and the lifting and connecting cup support component 54. This highly efficient system also allows the lifting and connecting cup support component 54 to continuously float and organize the cups and bowls during its descent, ensuring more orderly stacking. The lifting and connecting cup delivery nozzle 53 coordinates with the cup transfer position 52 to deliver cups and stacks the cups and bowls in the cup receiving and dropping channel 51, in conjunction with the lifting and connecting cup support component 54.

[0092] For example, the cup-feeding nozzle 53 is in transmission connection with a nozzle lift drive 57, which drives the nozzle 53 up and down. The cup-receiving support component 54 is in transmission connection with a cup-receiving servo motor 58, which drives the support component 54 up and down. During the overall lifting process, the support component 54 can additionally float (shake up and down) to organize the cups and bowls.

[0093] For example, the nozzle lift drive 57 may include a dual-stroke cylinder assembly (e.g., a dual-stroke cylinder, a double-ended cylinder, or two connected cylinders) or a drive motor (directly driving the dual-stroke lowering of the cup-feeding nozzle 53). The cup-feeding lifting component 54 is connected to the cup-feeding servo motor 58 via a screw-nut transmission mechanism. The various transmission connection methods are discussed below.

[0094] The cup receiving and dropping channel 51 is surrounded by a cup receiving rod and / or a cup receiving plate, which enclose the cup receiving and dropping channel 51. If the cup receiving rod and / or the cup receiving plate are installed on the cup receiving bracket 59, installation and setting are convenient.

[0095] A translational cup outlet 60 may be provided beside the cup receiving and dropping channel 51 so that the (completely stacked) cups and bowls on the cup receiving component 55 can be discharged from the translational cup outlet 60. For example, the cup receiving component may include a translational cup discharge conveying component 61 (e.g., a conveyor belt), which can cooperate with the cup receiving component to translate and convey the cups and bowls out through the translational cup outlet 60.

[0096] In addition, the cup receiving and dropping channel 51 is also equipped with a front-to-back or left-to-right stacking side-shooting mechanism 62. The front-to-back or left-to-right stacking side-shooting mechanism 62 includes a side-shooting component and a side-shooting driving component (such as a cylinder or motor, etc.). The side-shooting component is transmission-connected to the side-shooting driving component, and the side-shooting driving component drives the side-shooting component to perform side-shooting, thereby side-shooting and arranging the cups and bowls stacked in the cup receiving and dropping channel 51. For example, the front-to-back or left-to-right stacking side-shooting mechanism 62 is disposed above the cup-moving outlet 60 of the cup receiving and dropping channel 51. The stacked cups and bowls can be arranged through side-shooting before being subsequently discharged from the cup-moving outlet 60.

[0097] The oil dipping device and preheating device are relatively mature technologies in paper cup forming machines, and existing conventional oil dipping devices and preheating devices can be used. In addition, if the oil dipping device uses a lifting oil dipping component (which can be additionally equipped with a spring buffer), the cup rim oil dipping station 29 can also be equipped with a lifting oil dipping base to cooperate with the lifting oil dipping component above it. The lifting oil dipping base is equipped with an oil dipping base buffer return spring. The lifting oil dipping base and the lifting oil dipping component can clamp the cup body and lower it for oil dipping. After the oil dipping is completed, it can rise and return to its original position, facilitating oil dipping and translational conveying by the translation robot. For example, the preheating device may include a lifting preheating component (having a heating element (such as an electric heating wire or electric heating tube, etc.) and may be additionally equipped with a spring buffer). The cup rim preheating station 30 may also be equipped with a lifting preheating base that cooperates with the lifting preheating component above. The lifting preheating base is equipped with a preheating base buffer return spring. The lifting preheating base and the lifting preheating component can clamp the cup body and lower it for preheating. The lowered position is also equipped with a preheating unit (such as hot air blowing or steam) that provides additional heating for the cup rim. After preheating is completed, it can rise and return to its initial position, facilitating preheating and translational conveying by a translational robot. Alternatively, the lifting preheating component may not have a heating element and may simply cooperate to clamp the cup body and lower it, with the preheating unit performing the preheating.
