Description

Technical Field

[0001] The invention belongs to the field of cake base production, in particular to a cake base production line. Background Art

[0002] In the prior art, the traditional method of making cake trays is to manually fold the die-cut top cover, then put in a filler foam board, and then cover the bottom plate coated with glue to seal it to form a preliminary tray, and finally die-cut and cut the preliminary tray into the required size to finally obtain a formed cake tray. However, it is found in the current tray production process that only by gluing, it is easy to cause the bonding time between the top cover, foam board and bottom plate to be too long, which reduces the production efficiency of the tray, and it is found that during the loading process or later use, the glue coating is prone to cracking, which makes the adhesion between the top cover, foam board and bottom plate not firm, resulting in poor molding quality of the tray, which seriously affects the use of the tray.

[0003] In addition, although there is a device for folding the top cover designed in the production process of the base, it can only meet the folding of the oblique edge of the top cover. The inner edge of the top cover needs to be folded manually and then sent into the current top cover folding device. Otherwise, the top cover folding failure will occur, resulting in high manual operation costs, low production efficiency and low automation level in the entire processing process of the top cover.

[0041] The beneficial effects of the present invention are:

[0042] 1. The present invention can automatically complete the processing of the base plate through the design of a conveying unit, a top cover loading unit, a foam board loading unit, a gluing unit, a bottom plate loading unit, a heating unit and a die-cutting unit, thereby ensuring the molding quality of the base plate while greatly reducing labor costs, improving the processing efficiency of batch molding of the base plate, and realizing automatic and uninterrupted production of the base plate to meet the needs of batch production; wherein, through the design of the shaping device, the feeding assembly is used to transmit the top cover to four groups of shaping devices for shaping the inner edge of the top cover, thereby reducing the current manual inner edge folding operation and greatly improving the processing efficiency and automation level.

[0043] 2. The present invention ensures the straight-line movement of the top cover during the feeding process through the design of the pressing wheel mechanism, reduces the deviation, and improves the shaping effect of the subsequent top cover; when the four corners of the top cover correspond to each group of shaping devices, the top cover to be shaped is limited by the blocking mechanism, which is convenient for better shaping;

[0044] Specifically, through the design of the inner edge folding mechanism and the oblique edge paper pressing mechanism, during the shaping process of the inner edge of the top cover, the pressing block is driven by the paper pressing cylinder to be pressed down to the oblique edges on both sides of each corner, and then the inner edge of each corner of the top cover is folded inward by the upward movement of the telescopic column below, completing the shaping operation of the inner edge of the top cover. The present invention can complete the folding and shaping of the inner edges of the four corners of the top cover, reducing the current manual operation of folding the inner edges, greatly simplifying the production time of the bottom bracket, and improving the production efficiency of the bottom bracket.

[0045] 3. Through the design of the auxiliary support mechanism, the present invention can position several templates when the conveying unit conveys them to the top cover loading unit, the foam board loading unit, the bottom board loading unit and the die-cutting unit. The template is lifted up by the supporting assembly of the auxiliary support mechanism, the conveyance of the template on the conveying unit is stopped, and two groups of stop column assemblies are used to limit the position of the current single template. Combined with the function of the non-return assembly, the reverse conveyance of the template can be avoided, thereby ensuring the stable transportation of the template and improving the processing stability during the entire production line.

[0046] 4. The present invention can ensure that when the foam board is discharged, the foam board will not be offset under the action of the two side plugs, which is convenient for the subsequent operation of the foam board pushing mechanism and the fixture suction cup mechanism; the design of the baffle assembly can ensure that a single foam board passes through the bridge plate, and can avoid the interference of the next foam board during the adsorption process of the current foam board, thereby improving the stability and accuracy of the foam board during the adsorption process;

[0047] Moreover, the design of multiple unloading silos here can adapt to different production needs and realize the cyclic unloading of foam boards in each unloading silo. When it is necessary to increase or decrease the production capacity of the base, the operating number of the unloading silos can be quickly adjusted without large-scale transformation of the entire production line. The unloading silos designed side by side here are relatively independent and easy to maintain and overhaul. When one of the unloading silos needs maintenance, the other unloading silos can continue to work normally, reducing the time of production interruption and improving production efficiency.

[0048] 5. Through the design of the foam board pushing mechanism, the present invention can quickly push the foam board transmitted by the dial plate transmission mechanism from the bottom plate to the bridge plate, and then push it from the bridge plate to the support plate on the corresponding auxiliary support mechanism. Here, under the action of the limiting component, the position displacement of the foam board during the pushing process can be avoided, and the position of the foam board pushed to the support plate can be adjusted until it is directly below the clamp suction cup mechanism, and the foam board is clamped by a pair of clamps, and then the foam board is sucked by the foam board suction cup. Here, the position of the foam board suction cup corresponds to the installation groove formed in the molded top cover, which is convenient for the subsequent placement of the foam board and improves the adaptability of the foam board installation.

[0049] 6. The present invention can be applicable to the use of top covers, foam boards and bottom boards of different sizes through the design of size adjustment device 1, size adjustment device 2 and size adjustment device 3, thereby expanding the processing and production needs of bases of different sizes.

[0050] 7. Through the design of the pressing plate mechanism, the present invention can use the pressing plate mechanism to press the assembled foam board before it enters the gluing mechanism, thereby preventing the foam board from rising, improving the fit of the foam board in the installation groove, improving the accuracy of subsequent gluing, and reducing the coating of glue on the foam board.

[0051] 8. The present invention adopts the design of the heating unit. Under the action of the heating plate and the air blowing pipe, not only can the bubbles in the glue escape more easily, the surface will be smoother, thereby improving the bonding quality, but also can accelerate the drying and curing of the glue, improve the bonding effect between the bottom plate, the foam board and the top cover, shorten the bonding time, and improve the production efficiency and initial molding quality of the bottom bracket.

[0052] 9. Through the design of the limit detection mechanism, the present invention can use the limit detection mechanism to detect whether the height of the initial formed base after bonding meets the requirements after the heating unit is processed. If it meets the requirements, it will continue to be transmitted to the die-cutting unit through the conveying unit for die-cutting processing. If it does not meet the requirements, the detection switch will promptly alarm and stop the current transportation and other operations, and contact the technician for timely adjustment, which greatly reduces the scrap rate of the base and improves the molding quality of the base.

[0053] 10. The present invention is capable of continuously die-cutting the initially formed base tray through the design of two sets of die-cutting units. Specifically, through the design of the die-cutting material picking mechanism, the base tray to be die-cut can be sent to the die-cutting device for die-cutting through the suction of two sets of die-cutting material picking suction cups. At the same time, the formed base tray after die-cutting can be sucked from the die-cutting device and sent to the next process for base tray collection, so that the feeding and discharging of the base tray can be carried out simultaneously, thereby improving the processing efficiency.

[0079] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0080] In a specific embodiment of the present invention, Figure 1-22 As shown, a cake base production line comprises a frame 1 and a conveying unit 2 arranged on the frame 1, and a top cover feeding unit 3, a foam plate feeding unit 4, a gluing unit 5, a bottom plate feeding unit 6, a heating unit 7 and a die-cutting unit 8 arranged in sequence along the conveying direction of the conveying unit 2, and auxiliary support mechanisms 9 are respectively arranged on the frame 1 for cooperating with the top cover feeding unit 3, the foam plate feeding unit 4, the bottom plate feeding unit 6 and the die-cutting unit 8 for processing, and the conveying unit 2 cyclically transmits a plurality of templates 100 to the top cover feeding unit 3, the foam plate feeding unit 4, the gluing unit 5, the bottom plate feeding unit 6, the heating unit 7 and the die-cutting unit 8 for cooperating processing, and the plurality of templates 100 are positioned by the auxiliary support mechanism 9, and the auxiliary support mechanism 9 comprises a supporting component 91, a non-return component 92 and two groups of stop column components 93, the two groups of stop column components 93 are located on both sides of the supporting component 91, and the non-return component 92 is arranged on the outside of the stop column component 93 and is located on the front side of the conveying direction of the conveying unit 2,

[0081] The present invention can complete the processing of the base plate automatically through the design of the conveying unit, the top cover feeding unit 3, the foam plate feeding unit 4, the gluing unit 5, the bottom plate feeding unit 6, the heating unit 7 and the die-cutting unit 8, thereby ensuring the quality of the base plate molding, greatly reducing the labor cost, improving the processing efficiency of the base plate batch molding, realizing the automatic and uninterrupted production of the base plate, and meeting the needs of batch production;

[0082] Through the design of the auxiliary support mechanism 9, it is possible to position several templates 100 when the conveying unit 2 conveys them to the top cover loading unit 3, the foam board loading unit 4, the bottom board loading unit 6 and the die-cutting unit 8. The template 100 is lifted up by the supporting component 91 of the auxiliary support mechanism 9, and the conveyance of the template 100 on the conveying unit 2 is stopped. The position of the current single template 100 is limited by two sets of stop column components 93. Combined with the function of the non-return component 92, the reverse conveyance of the template 100 can be avoided, thereby ensuring the stable transportation of the template 100 and improving the processing stability during the entire production line.

[0083] like Figure 2-6The top cover loading unit 3 includes a frame 2 31, a top cover unloading device 32, a shaping device 33, a flanging device 34 and a material taking device 35. The frame 2 31 is fixed to one side of the frame 1. The frame 2 31 is provided with a supporting beam 311 and a second slide rail 312. The supporting beam 311 has three supporting plates 313, and the upper parts of the two outer supporting plates 313 are respectively provided with protective plates 335. The second slide rail 312 has a pair of symmetrically arranged on the outer sides of the three supporting beams 311. The second 312 is provided with a feeding assembly 36 slidably connected thereto, the shaping device 33 is located between the top cover discharging device 32 and the flanging device 34, the picking device 35 is arranged on one side of the flanging device 34 and is located above the frame 1, the top cover 200 in the top cover discharging device 32 is transferred to the shaping device 33 for shaping through the feeding assembly 36 and then transferred to the flanging device 34 for flanging, and then the flanging-formed top cover is sucked onto the template 100 by the picking device 35 through the picking suction cup 353;

[0084] Specifically, the top cover discharge device 32 in this embodiment includes a clamping mechanism 321 and a suction cup mechanism 322. The clamping mechanism 321 is fixed on the upper side of the frame 31 through a bracket 1 323. The suction cup mechanism 322 is arranged below the clamping mechanism 321. The clamping mechanism 321 includes a clamping bottom plate 3211 and a cone rod 3212. The clamping bottom plate 3211 is fixed on the frame 31 through a bracket 1 323. The cone rod 3212 has a plurality of cone rods 3212 and is respectively installed on the four sides of the clamping bottom plate 3211 through cone rod seats 3213. Waist-shaped holes are arranged on the four sides of the clamping bottom plate 3211 and each cone rod seat 3213, and the two are fixed by fasteners.

[0085] The top cover 200 of the present invention is stored in the clamping mechanism 321, and the top cover 200 is sucked and placed on the support plate 313 by the suction cup mechanism 322 below the clamping mechanism 321. In this embodiment, the suction cup mechanism 322 can be a lifting suction cup structure in the prior art, so the specific structure is not repeated;

[0086] In this embodiment, the design of the cone rod 3212 eliminates the need to design a separate limit plate to prevent the top cover 200 from falling, and the bottom arc surface design of the cone rod 3212 makes it easier for the suction cup mechanism 322 to absorb. Here, the design of waist-shaped holes on the four sides of the clamping bottom plate 3211 and each cone rod seat 3213 can meet the storage needs of top covers of different sizes, and indirectly meet the processing needs of bases of different sizes, with a wide range of applications.

[0087] like Figure 4The shaping device 33 has four groups, and two groups are respectively arranged on the protective plates 335 on both sides. Each group of shaping devices 33 includes an inner edge folding mechanism 331, a pressing wheel mechanism 332, a bevel paper pressing mechanism 333 and a material blocking mechanism. The inner edge folding mechanism 331 is arranged below the support plate 313, the pressing wheel mechanism 332 and the bevel paper pressing mechanism 333 are arranged above the support plate 313, and the material blocking mechanism is arranged on the frame 2 31 and is located on the outside of the inner edge folding mechanism 331. The inner edge folding mechanism 331 includes a material pushing cylinder and a telescopic column 3311 driven by the material pushing cylinder. The pressing wheel mechanism 332 includes a pressing wheel frame 3321 and a pressing wheel 3322.

[0088] The present invention uses the design of the shaping device 33 and the feeding assembly 36 to transfer the top cover 200 to the four groups of shaping devices 33 for shaping. In the process of transferring the top cover 200, the pressing wheel mechanism 332 is used to ensure the straight running of the top cover 200 during the feeding process, thereby reducing the deviation and improving the shaping effect of the subsequent top cover 200. When the four corners of the top cover 200 correspond to each group of shaping devices 33, the top cover 200 to be shaped is limited by the blocking mechanism to facilitate better shaping. At this time, the inner edge folding mechanism 331 and the bevel mechanism 332 are used to prevent the top cover 200 from running in a straight line during the feeding process. The design of the edge paper pressing mechanism 333 is that the pressing block 3333 is driven by the paper pressing cylinder 3332 to press down to the oblique edges 201 on both sides of each corner, and then the inner edge 202 of each corner of the top cover is moved upward by the telescopic column 3311 below to be folded inward to complete the shaping operation of the top cover. The present invention can complete the folding and shaping of the inner edges 202 of the four corners of the top cover 200, reducing the current manual folding of the inner edges, greatly simplifying the production time of the bottom bracket, and improving the production efficiency of the bottom bracket; the structural diagram of the top cover 200 in this embodiment is shown in FIG.

A cylinder mounting plate 2 354 is fixedly arranged on the material picking slide 352, and a material picking cylinder 355 is installed on the cylinder mounting plate 2 354. The output end of the material picking cylinder 355 is connected to a connecting seat 356, and a connecting rod 357 is fixedly connected to the lower part of the connecting seat 356. The material picking suction cup 353 is arranged at the end of the connecting rod 357 away from the connecting seat 356.

[0091] The present invention uses the material taking device 35 to suck the top cover after the flange forming to the support plate 912 of the corresponding auxiliary support mechanism 9, and then starts to transfer the template carrying the top cover to the auxiliary support mechanism 9 corresponding to the foam board feeding unit 4 through the conveying unit;

Both ends of the connecting rod 364 are provided with a paper pusher 363. Here, the transmission mechanism can be a belt transmission or a chain transmission, so the specific structure is not repeated here.

[0093] The present invention uses a suction cup mechanism 322 to suck the top cover 200 in the clamping mechanism 321 from the bottom of the clamping mechanism 321 and place it on the support plate 313, and then transmits it to the shaping device 33 for shaping through the feeding assembly 36, and then transmits it to the flanging device 33 for flanging forming, and then sucks the top cover after flanging forming through the material picking device 35 and moves it to the template 100 for transmission to the foam board feeding unit 4.

[0094] like Figure 7 The support assembly 91 includes a support base plate 911, a support plate 912 and a support cylinder 913. The support base plate 911 is fixed on the frame 1.

The two ends of the lifting plate 933 are penetrated with blocking columns 934.

[0096] Specifically, the present invention, through the design of the auxiliary support mechanism 9, can, when the template 100 is transmitted to the top cover feeding unit 3, the foam board feeding unit 4, the bottom board feeding unit 6 and the die-cutting unit 8 through the conveying unit 2 for processing, the corresponding support plate 912 will lift the template 100 and separate it from the transmission of the conveying unit 2, and under the action of the two groups of stop column assemblies 93, the movement of a single template 100 is limited, and the interference of the next template 100 is also avoided, thereby improving the stability during processing;

[0097] like Figure 8-12 The foam plate feeding unit 4 includes a frame 3 41, a lower material bin 42, a paddle transmission mechanism 43, a foam plate pushing mechanism 44 and a clamp suction cup mechanism 45.

A plurality of lower material bins 42 are arranged at one end of the pair of cross beams 3 49, and a limit assembly 492 is arranged at the other end.

[0098] Here, the design of the baffle assembly 48 can ensure that a single foam board passes through the bridge plate, and can avoid interference from the next foam board during the adsorption process of the current foam board, thereby improving the stability and accuracy of the foam board adsorption process;

[0099] Several unloading bins 42 are located above the bottom plate 46, and the paddle transmission mechanism 43 is arranged below the several unloading bins 42. The bottoms of the several unloading bins 42 are provided with unloading ports, and each unloading port is opened and closed by a plug-in plate assembly 410. Each plug-in plate assembly 410 includes plug-ins 4101 symmetrically arranged on both sides of the unloading port, and each plug-in plate 4101 is driven to extend into or away from the unloading port by a plug-in plate cylinder; here, through the design of the plug-in plate assembly 410, it can be ensured that when the foam board is unloaded, under the action of the plug-ins 4101 on both sides, the foam board will not be offset, which is convenient for the subsequent operation of the foam board pushing mechanism 44 and the clamp suction cup mechanism 45;

[0100] Each limiting assembly 492 includes a limiting plate 4921 and a limiting cylinder 4922. The limiting cylinder 4922 is fixed to the outside of the beam 49, and its output end is connected to the limiting plate 4921. A stopper 4923 is provided on the inner side of the limiting plate 4921.

[0102] The fixture suction cup mechanism 45 includes a bracket 2 451, a linear slide 452, a driving cylinder 453 and a foam plate suction cup 454.

The foam plate suction cup 454 is arranged on the inner side of the pair of clamping plates 459.

[0103] In this embodiment, there are three material discharge bins 42, and materials can be discharged through the three material discharge bins 42 to improve industrial production efficiency.

[0104] Specifically, the foam board in the material discharge bin 42 falls downward from the material discharge port onto the plate-pulling transmission mechanism 43 under the control of the inserting plate assembly 410, and the foam board is driven to be transferred toward the direction close to the foam board pushing mechanism 44 under the action of the plate-pulling plate 431;

[0105] And through the design of the foam plate pushing mechanism 44, the foam plate transmitted by the plate transmission mechanism 43 can be quickly pushed from the bottom plate 46 to the bridge plate 47, and pushed from the bridge plate 47 to the corresponding support plate 912 on the auxiliary support mechanism 9. Here, under the action of the limit assembly 492, the position of the foam plate pushed to the support plate 912 can be adjusted until it is directly below the clamp suction cup mechanism 45, and the foam plate is clamped by a pair of clamps 459, and then the foam plate is sucked by the foam plate suction cup 454. Here, the position of the foam plate suction cup 454 corresponds to the installation groove formed in the molded top cover, which is convenient for the subsequent placement of the foam plate;

[0106] At this time, the template carrying the formed top cover is transported to the auxiliary support mechanism 9 corresponding to the foam feeding unit through the conveying unit. Under the action of the auxiliary support mechanism 9, the template carrying the formed top cover is lifted up. At this time, the driving cylinder 453 drives the reciprocating slider 455 to descend, and synchronously drives the foam board suction cup to descend. Finally, the sucked foam board is placed in the installation groove of the formed top cover to complete the processing of the foam feeding unit. Then the support plate descends, and the two sets of blocking columns 934 descend. The template carrying the foam board and the formed top cover begins to be conveyed to the gluing unit through the conveying unit.

[0115] Specifically, the glue coating mechanism 52 includes a protective seat 521, a glue spraying nozzle, and a conveying roller 522 and a rubber roller 523 inserted between the two protective seats 521. The conveying roller 522 is located below the pressure plate 1 513, and the rubber roller 523 is located above the pressure plate 1 513.

The inner push plate 642 is connected to the inner pressure plate 641, and the inner pressure plate 641 is located on the inner side of the adjustment rod 617; by driving the inner push cylinder 643 to drive the inner push plate 642 to move inward, that is, driving the inner pressure plate 641 to move inward, the position of the bottom plate is adjusted to avoid the offset phenomenon, which causes the bottom plate to have a directional deviation when the suction cup is sucked, thereby improving the accuracy of the combination of the bottom plate and the foam plate;

[0121] Specifically, a transition plate 67 is provided between the mounting frame 611 and the frame 1, and a baffle mechanism is provided below the transition plate 67. The baffle mechanism includes a U-shaped baffle 661 and a baffle cylinder. The baffle cylinder drives the U-shaped baffle 661 to move upward to block the bottom plate from passing through the transition plate 67. The design of the baffle mechanism can ensure that a single bottom plate passes through the bottom of the bottom plate suction cup mechanism 63 for processing.

[0122] The size adjustment device 3 65 includes a screw adjustment component 3 651 and a slider adjustment component 3 652.

[0123] In this embodiment, the material-resisting mechanism 614 includes an adjusting column 6142 and a material-resisting plate 6141. The adjusting column 6142 is installed on a sliding rod 6144 through an adjusting block 6143. The sliding rod 6144 is inserted into the bottom plate material rack 612. An adjusting plate 6145 is inserted above the adjusting column 6142. A connecting rod 6146 is inserted into the adjusting plate 6145. The connecting rod 6146 is fixed to the material-resisting plate 6141. The material-resisting plate 6141 has two inclined plates, and the inclination angle can be 30°, that is, the angle with the horizontal line. The inclined design can lift one side of the bottom plate, and the other side can realize single-sheet transmission under the drive of the belt transmission mechanism.

[0124] The material blocking mechanism 615 includes a mounting bracket 6151 and a material blocking plate 6152. The mounting bracket 6151 is mounted on the base plate loading rack 612. The material blocking plate 6152 has two bottom ends and a gap is provided between the bottom end and the belt of the belt conveyor mechanism 613 for conveying a single base plate. Here, the position of the adjustment block 6143 on the slide rod 6144 can be adjusted according to the size of the base plate and then fastened by fasteners. The position of the connecting rod 6146 in the adjustment plate 6145 can be adjusted and then fastened by fasteners, that is, the position of the material blocking plate 6141 can be adjusted. Similarly, the position of the material blocking plate 6152 on the mounting bracket 6151 can also be adjusted and then fastened by fasteners. Since this can be achieved with existing technical means, the specific structure will not be repeated.

[0125] The working principle of the bottom plate feeding unit is as follows: the bottom plate comes out from the gap between the baffle plate 6152 of the baffle mechanism 615 and the belt of the belt conveyor mechanism 613, and then continues to be conveyed by the belt conveyor mechanism 613, and is driven by the bottom plate lever mechanism 62 to quickly pass through the transition plate 67, and the direction of the bottom plate is adjusted by the direction adjustment mechanism 64 to avoid deviation, and then is sucked by the bottom plate suction cup mechanism 63 until the bottom plate is sucked and placed on the above-mentioned glue-coated molded top cover with the foam plate, and is pressed down by the suction cup of the bottom plate suction cup mechanism 63 to preliminarily adhere the bottom plate to the foam plate and the top cover;

[0126] In this process, the molded top cover equipped with the foam board is positioned by the auxiliary support mechanism. The specific positioning process is similar to the above, so the working principle of the auxiliary support mechanism is not repeated here.

[0127] like Fig.17 The heating unit 7 includes a stand 71, a downward pressure cylinder 72, an upper template 73, a heating plate 74, a blowing pipe 75 and a lower template 76. The stand 71 is fixed on the frame 1. The downward pressure cylinder 72 is installed on the stand 71 and its output end passes through the stand 71 and is connected to the upper template 73. The upper template 73 is connected to the heating plate 74 through a limit bolt. A plurality of springs 77 are arranged between the heating plate 74 and the upper template 73. The heating plate 74 is provided with a thermocouple 78 and a plurality of heating rods 79. The heating plate 74 is provided with a plurality of blowing holes. Each blowing hole is provided with a blowing pipe 75. The blowing pipe 75 is installed on the upper template 73 and its blowing nozzle faces the blowing hole. The lower template 76 is located below the heating plate 74. The lower template 76 is driven by the bottom cylinder to approach or separate from the heating plate 74.

[0128] The present invention adopts the design of the heating unit 7. Under the action of the heating plate 74 and the air blowing pipe 75, not only can the bubbles in the glue escape more easily, the surface will be smoother, thereby improving the bonding quality, but also the drying and curing of the glue can be accelerated, the bonding effect between the bottom plate, the foam board and the top cover can be improved, the bonding time can be shortened, and the initial molding quality of the base can be improved.

[0129] like Fig.18 A limit detection mechanism 710 is provided on one side of the vertical frame 71. The limit detection mechanism 710 includes a bracket 5 7101, a horizontal plate 7102, a stop column cylinder 7103 and a limit plate 2 7104.

A detection switch 7105 is provided on one side of the limit plate 2 7103. A plurality of guide columns 7106 are provided between the limit plate 2 7104 and the horizontal plate 7102.

[0130] The present invention can detect whether the height of the initially formed base after bonding meets the requirements through the design of the limit detection mechanism 710. If it meets the requirements, it will continue to be transmitted to the die-cutting unit 8 through the conveying unit 2 for die-cutting processing.

[0131] like Figure 19-20 The die-cutting units 8 have two groups and are relatively arranged on one side of the frame 1. Each group of die-cutting units 8 includes a die-cutting material taking mechanism 81 and a die-cutting device 82. The die-cutting material taking mechanism 81 includes a frame 6 811 and a die-cutting material taking suction cup 812. The frame 6 811 is fixedly arranged on one side of the frame 1, and a die-cutting slide rail 813 is arranged above it. The die-cutting slide rail 813 is provided with two groups of die-cutting sliders 814 slidably connected thereto. The die-cutting material taking suction cup 812 has two groups and is relatively arranged on the corresponding die-cutting sliders 814.

[0132] The present invention can continuously perform die-cutting on the initially formed base through the design of two sets of die-cutting units 8. Here, through the design of the die-cutting material taking mechanism 81, the base to be die-cut can be sent to the die-cutting device 82 for die-cutting through the suction of two sets of die-cutting material taking suction cups 812. At the same time, the formed base after die-cutting can be sucked from the die-cutting device 82 and sent to the next process for base collection, so that the feeding and discharging of the base can be carried out simultaneously, thereby improving the processing efficiency.

[0133] Here, cutting and shaping are performed by a die-cutting device 82 to finally form the required base. The die-cutting device 82 can use a die-cutting machine commonly used in the prior art, so the specific structure is not described in detail.

[0134] like Figure 21-22 The conveying unit 2 includes an upper conveying mechanism 21, a lower conveying mechanism 22 and a conveying transfer mechanism 23. The upper conveying mechanism 21 is located above the lower conveying mechanism 22 and its two ends are shorter than the length of the lower conveying mechanism 22. A plurality of templates 100 are transmitted to the upper conveying mechanism 21 or the lower conveying mechanism 22 through the conveying transfer mechanism 23. The conveying transfer mechanism 23 has two groups and is respectively arranged at the two ends of the lower conveying mechanism 22. Each group of conveying transfer mechanisms 23 includes a vertical rail 231, a template bracket 232 and a lifting cylinder 233. The vertical rail 231 has a pair and is symmetrically arranged on the frame 1. The template bracket 232 is slidably arranged on a pair of vertical rails 231. The lifting cylinder 233 is arranged on the frame 1, and its output end is fixed to the template bracket 232. A plurality of groups of blocking column assemblies 93 for blocking the template 100 are arranged on the frame 1 close to the top cover loading unit 3;

[0135] The present invention can realize the purpose of uninterrupted up-and-down circulation conveying on the frame 1 through the design of the conveying unit 2, thereby improving the processing efficiency. In combination with the design of the conveying transfer mechanism 23, the empty template can be transferred to the upper conveying mechanism 21 during processing, and then processed in each process in sequence through the top cover feeding unit 3, the foam board feeding unit 4, the gluing unit 5, the bottom board feeding unit 6, the heating unit 7 and the die-cutting unit 8;

[0136] After the die-cutting process in the die-cutting unit 8, the empty template is transported to the lower conveying mechanism 22 through the rear conveying transfer mechanism 23, and then the empty template is cyclically transported to the front conveying transfer mechanism 23 through the transmission of the lower conveying mechanism 22, and the cycle is repeated.

[0137] In this embodiment, the upper conveying mechanism 21 and the lower conveying mechanism 22 can be conveyor belt conveying mechanisms, and the specific structure is not repeated here; here, through the design of the blocking column assembly 93, it can ensure that the single template on the lower conveying mechanism 22 is conveyed to the upper conveying mechanism 21 through the conveying transfer mechanism 23, so as to ensure that the single template is transmitted to the top cover loading unit 3, the foam board loading unit 4, the gluing unit 5, the bottom board loading unit 6, the heating unit 7 and the die-cutting unit 8 in sequence through the conveying transfer mechanism 23. Of course, after the current process is completed, when the template is input into the next process, the next template can be conveyed to the upper conveying mechanism 21 for processing through the conveying transfer mechanism 23 through the blocking column assembly 93.

[0138] The specific working principle of the present invention is:

[0139] The template 100 is transferred from the lower conveying mechanism 22 to the upper conveying mechanism 21 through the conveying transfer mechanism 23, and then sequentially passes through the top cover feeding unit 3, the foam board feeding unit 4, the gluing unit 5, the bottom board feeding unit 6, the heating unit 7 and the die-cutting unit 8 to complete the processing, and finally the processing of the bottom bracket is realized. Specifically, the top cover in the top cover discharge device 32 is conveyed to the shaping device 33 through the feeding assembly 36 to shape the inner edge 201 of the top cover 200, and then conveyed to the flanging device 34 to fold the bevel 202, and then the flanging-formed top cover is sucked and placed on the template currently conveyed to the bottom of the fetching device 35 through the picking device 35, and then conveyed to the foam board feeding unit 4 through the upper conveying mechanism 21;

[0140] The foam board of the foam board feeding unit 4 is transferred by the plate transfer mechanism 43, and is pushed by the auxiliary foam board push mechanism 44, and finally adsorbed by the clamp suction cup mechanism 45 until the template is transferred to the corresponding lower position, and then the adsorbed foam board is placed in the installation groove of the flanged top cover through the clamp suction cup mechanism 45;

[0141] Then, it is transferred to the gluing unit 5 through the upper conveying mechanism 21 for pressing first and then gluing, and then transferred to the bottom plate feeding unit 6, where the bottom plate is placed on the glued foam plate and the top cover for preliminary pressing and forming;

[0142] Then, the glue is transferred to the heating unit 7 through the upper conveying mechanism 21 to accelerate the rapid drying and curing of the glue, thereby improving the bonding effect between the bottom plate, the foam plate and the top cover, and improving the initial molding quality of the bottom bracket. In addition, during the heating process, the bonding quality between the bottom plate, the foam plate and the top cover is improved by the downward pressure of the downward pressure cylinder 72.

[0143] The limit detection mechanism 710 detects whether the bonding height meets the requirements. If it meets the requirements, it is further transmitted to the die-cutting unit 8 through the upper conveying mechanism 21 for die-cutting. The two sets of die-cutting units 8 are used to cycle the die-cutting to improve the final forming effect of the base. The die-cutting material collection mechanism 81 is used to send the die-cut base to the next process for collection.

[0144] Finally, the empty template processed by the die-cutting unit is transported to the lower conveying mechanism 22 through the conveying transfer mechanism 23 for circulation, and the operation is repeated to ensure the continuity and stability of the base during the production process.

[0145] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
