Description

Technical Field

[0001] The invention relates to cake base production equipment, in particular to automatic cake base production equipment. Background Art

[0002] The cake base is a base used to support the cake. The structure of the cake base includes a base paper 1, a foam board 2 and a cover paper 3. The size of the foam board is slightly smaller than the base paper. The foam board is located on the upper side of the base paper. The cover paper needs to be processed to form a cavity inside it to accommodate the foam board. Then the cover paper completely wraps the foam board and fits and fixes it to the edge of the base paper, making the cake base look like a "dish" (refer to the attached picture). Figure 1 The outline of the cake base is mainly round or square. During the production process of the cake base, the base paper, foam board and cover paper need to be stacked in order and fixed together with glue.

[0003] Previously, cake base production used a combination of manual labor and semi-automated equipment, resulting in low production efficiency and yield, and high production costs. Later, the production process for cake bases was broken down into multiple sub-steps, and corresponding equipment was developed to automate these steps. These included gluing equipment for gluing the base paper, forming equipment for stretching the top paper, laminating equipment for pressing the base paper, foam board, and top paper together, and trimming equipment for trimming the semi-finished product after lamination. This significantly improved the production efficiency of each sub-step and enhanced quality control. However, this also required considerable manual labor to transport the semi-finished products and raw materials.

[0004] Therefore, in order to improve the production efficiency of cake bases and reduce labor costs, the cake base industry urgently needs to develop a cake base production equipment with high integration and high degree of automation. Summary of the Invention

[0005] The invention provides an automatic production device for cake bases, which solves the problem in the prior art that the production of cake bases requires multiple devices.

[0006] The above technical problems of the present invention are mainly solved by the following technical solutions: an automatic production device for cake trays, characterized in that it includes:

[0007] The circulating transmission device comprises: a mounting base, which is fixedly arranged horizontally, and a first slide groove is provided on the length direction of the upper surface thereof, and a second slide groove is provided at the bottom of the mounting base and is parallel to and opposite to the first slide groove; two track-changing windows are formed on the mounting base and are located at the front and rear ends of the first slide groove; two mold lifting assemblies, including a lifting module and a lifting platform driven by the same, and the two mold lifting assemblies are respectively arranged at the bottom of the two track-changing windows, and are correspondingly set as an upper mold lifting assembly and a lower mold lifting assembly, and the lifting module can drive the lifting platform to switch back and forth between the heights of the two slide grooves; 7 pieces of treatment The tool is slidingly assembled with 3 pieces in each of the first slide and the second slide, and the remaining piece is located on any lifting platform; two propulsion devices are divided into a first propulsion device arranged at the front end of the mounting base and facing rearward, and a second propulsion device arranged at the rear end of the mounting base and facing forward. The track change window area at the front end corresponds to the surface paper loading station, the first jig position in the first slide corresponds to the foam board loading station, the second jig position in the first slide corresponds to the bottom paper loading station, the third jig position in the first slide corresponds to the trimming and pressing station, and the track change window area at the rear end corresponds to the bottom supporting and unloading station;

[0008] Three sets of suction cup handling assemblies are respectively arranged on the upper sides of the surface paper loading station, the bottom paper loading station and the bottom supporting and unloading station;

[0009] A set of gripping and handling components is provided on the upper side of the foam board loading station;

[0010] A set of trimming and pressing components is arranged on the upper side of the trimming and pressing station.

[0011] Furthermore, the trimming and pressing assembly includes a plurality of guide pillars vertically fixed to the upper side of the trimming and pressing station, a hydraulic press fixed to the upper end of the guide pillars and an upper die assembly slidably mounted on the guide pillars, the upper die assembly includes an upper die plate, a first pad attached to the bottom surface of the upper die plate, a cutter positioning frame fixed to the lower side of the first pad, and an annular cutter fixed to the cutter positioning frame, the cutting edge of the annular cutter is set vertically downward, the internal area defined by the annular cutter is movably provided with an inner pressure plate, the inner A first elastic member is connected between the pressure plate and the upper template, and a second pad is also attached to the bottom surface of the inner pressure plate; an annular outer pressure plate is movably provided on the outer side of the annular cutter, and a second elastic member is connected between the outer pressure plate and the cutter positioning frame, and a blade accommodating groove for accommodating the annular cutter is formed between the inner side wall of the outer pressure plate and the outer side wall of the inner pressure plate, and the outer pressure plate and the inner pressure plate can be reset downward under the rebound action of the second elastic member and the first elastic member until the annular cutter is retracted into the blade accommodating groove as a whole;

[0012] The jig includes a lower template and a punch arranged on the upper side of the lower template. A recessed portion is provided in the middle of the upper surface of the punch, and the contour of the recessed portion matches the raised portion of the surface paper. A third pad is attached to the upper surface of the punch, and the outer contour of the third pad is adapted to the inner contour of the annular cutter.

[0013] The operating principle of the trimming and pressing assembly is as follows: the hydraulic press pushes the upper mold assembly downward and approaches the jig below. The outer pressure plate and the second pad first contact the bottom paper and press the edge parts of the surface paper and the bottom paper onto the third pad. The raised parts of the foam board and the surface paper are also completely pushed into the lower recess and abut against the bottom of the lower recess. As the upper mold assembly continues to press downward, the elastic force applied to the outer pressure plate and the inner pressure plate by the second elastic member and the first elastic member continues to increase. The pressure of the outer pressure plate is used to keep the outer edge of the paper straight to avoid wrinkles during the trimming process. The pressure of the inner pressure plate is used to increase the pressure on the pasting part. The greater the pressure, the smoother the pasting. The more solid it is; during this process, the annular cutter in the blade accommodating groove gradually extends out and cuts the surface paper and the bottom paper until the annular cutter contacts the third pad. At this time, the trimming process is completed, but it is generally necessary to maintain this state for a few seconds to increase the adhesion strength between the papers; then the hydraulic press pulls the upper mold assembly upward to reset. Initially, the outer pressure plate and the inner pressure plate remain fixed under the rebound action of the elastic member, and the annular cutter begins to gradually retract into the blade accommodating groove, so as to ensure that the cake base and the waste edges will not be stuck on the annular cutter, and then the outer pressure plate and the inner pressure plate leave the cake base, and at this time the cake base and the waste edges remain on the jig. In the present invention, the jig mainly plays the role of transportation, surface paper positioning and as the lower mold in the trimming and pressing station.

[0014] The present invention includes five stations: a surface paper loading station, a foam board loading station, a bottom paper loading station, a trimming and pressing station, and a bottom support unloading station. The surface paper loading station uses a suction cup conveying assembly to grab and carry the already formed surface paper to a jig in the station; the foam board loading station uses a gripping and clamping conveying assembly to grab and carry the foam board to the surface paper in the station, and ensure that the foam board is completely or partially stuffed into the concave cavity of the surface paper; the bottom paper loading station uses a suction cup conveying assembly to grab and carry the bottom paper coated with glue to the foam board in the station, and ensure that the bottom paper and the surface paper are basically aligned; the trimming and pressing station uses a trimming and pressing assembly to press and trim the material on the jig; the bottom support unloading station uses a suction cup conveying assembly to suck away the bottom support and waste edges together to complete unloading. The formed surface paper, foam board and glue-brushed bottom paper used in the present invention can all be automatically fed by existing equipment.

[0015] The circulating transport mechanism operates as follows: Initially, the upper mold lift assembly is in the high position, with a jig on its corresponding lift platform; the lower mold lift assembly is in the high position, with its corresponding lift platform empty; and each of the two chutes contains three jigs. Upon startup, the first pusher pushes the jig on the upper mold lift assembly into the first chute, resets it, and pushes the jig at the rear end of the first chute onto the lift platform of the lower mold lift assembly. Both mold lift assemblies then lower their corresponding lift platforms to the low position. The second pusher pushes the jig on the lower mold lift assembly into the second chute, resets it, and pushes the jig at the front end of the second chute onto the lift platform of the upper mold lift assembly. The two mold lift assemblies then push their corresponding lift platforms back to the high position, beginning the next cycle. This allows each jig to move in sequence, from the top paper loading station, to the foam board loading station, to the backing paper loading station, to the trimming and laminating station, and finally to the bottom support unloading station. The interval between the two pushers' movements is determined by the processing time of the slowest processing station.

[0016] Furthermore, the suction cup transport assembly includes a horizontal servo slide assembly, a lifting cylinder driven to move back and forth by the horizontal servo slide assembly, a lifting plate driven to rise and fall by the lifting cylinder, and a plurality of suction cups arranged on the lifting plate, and the suction cups are arranged vertically downward.

[0017] Furthermore, the grasping and handling assembly includes a horizontal servo slide assembly, a lifting cylinder driven to move back and forth by the horizontal servo slide assembly, a lifting plate driven to rise and fall by the lifting cylinder, and four clamping cylinders arranged on the lifting plate. Each clamping cylinder is provided with a clamping plate, and the four clamping plates enclose a rectangular clamping cavity. The clamping plates are driven to move by the extension and retraction of the clamping cylinder to expand or shrink the clamping cavity.

[0018] Furthermore, a positioning cylinder is provided on the mounting base and on the side of the first slide. The axis of the cylinder rod of the positioning cylinder is perpendicular to the first slide. A top block is provided on the cylinder rod, and the top block can fix the jig against the side wall of the first slide. When the two propulsion devices are in standby mode, the jig in the first slide is in a stationary state. This stage corresponds to the loading and unloading and processing stages of the products to be processed on the jig at the corresponding workstations. Therefore, it is necessary to ensure that each jig is docked in a preset position. For this purpose, a positioning cylinder is provided for the jig on each workstation. When the jig is in a stationary state, the positioning cylinder will be ejected, and the top block on it will fix the jig against the side wall of the first slide. At the same time, the top block cooperates with the positioning groove on the jig, so that the jig is completely fixed and accurately positioned.

[0019] Furthermore, a front buffer cylinder is provided at the front end of the mounting base, and a first abutment block is provided on the cylinder rod thereof, which is directly facing the jig from the second slide; a rear buffer cylinder is provided at the rear end of the mounting base, and a second abutment block is provided on the cylinder rod thereof, which is directly facing the jig from the first slide, and the abutment block is made of rubber or plastic. Both track change windows are provided with a structure for limiting the jig, and the corresponding buffer cylinder needs to extend the abutment block in advance before the corresponding propulsion device is activated. In this way, when the propulsion device pushes the jig out, the jig will first contact the abutment block and continue to compress the buffer cylinder. This can slow down the jig in advance and reduce the impact force between the jig and the rear limiter and the front limiter, which is beneficial to reducing the vibration and impact noise of the entire equipment and can effectively increase the material life of the impact part.

[0020] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The present invention includes five workstations: a surface paper loading station, a foam board loading station, a bottom paper loading station, a trimming and pressing station, and a bottom support unloading station. The five workstations are connected in series through a circulating transmission device. The circulating transmission device has the function of a circulating conveying jig. The surface paper loading station, foam board loading station, and bottom paper loading station on the present invention can be combined with existing equipment to realize fully automated production of pallets; 2. The trimming and pressing component has the function of bonding and trimming the bottom paper, foam board and surface paper. BRIEF DESCRIPTION OF THE DRAWINGS

The lifting module can drive the lifting platform to switch back and forth between the heights of the two slides; 7 fixtures 200, 3 of which are slidingly assembled in the first slide and the second slide, and the remaining one is located on any lifting platform; two propulsion devices 400, specifically long cylinders, the end of which is provided with a rubber or plastic pusher 410, which is divided into a first propulsion device arranged at the front end of the mounting base and arranged toward the rear The first pushing device 401 and the second pushing device 402 provided at the rear end of the mounting base and arranged forwardly, the first pushing device can push the jig on the upper mold lifting assembly into the first chute, and the second pushing device can push the jig on the lower mold lifting assembly into the second chute; the track changing window area at the front end corresponds to the surface paper loading station, the first jig position in the first chute corresponds to the foam board loading station, the second jig position in the first chute corresponds to the bottom paper loading station, the third jig position in the first chute corresponds to the trimming and pressing station, and the track changing window area at the rear end corresponds to the bottom supporting and unloading station;

[0039] Three sets of suction cup handling assemblies 500 are respectively arranged on the upper side of the top paper loading station, the bottom paper loading station and the bottom supporting and unloading station;

[0040] A set of gripping and handling components 600 is provided on the upper side of the foam board loading station;

[0041] A set of trimming and pressing components 700 is arranged on the upper side of the trimming and pressing station.

[0042] See Figure 3 、 Figure 11 and Figure 12The trimming and pressing assembly includes four guide pillars 710 fixed vertically on the upper side of the trimming and pressing station, a hydraulic press 720 fixed on the upper end of the guide pillars, and an upper mold assembly slidably mounted on the guide pillars. The upper mold assembly includes an upper mold plate 730, a first pad 740 attached to the bottom surface of the upper mold plate, a cutter positioning frame 750 fixed to the lower side of the first pad, and an annular cutter 760 fixed to the cutter positioning frame. The cutting edge of the annular cutter is set vertically downward, and the internal area defined by the annular cutter is movably provided with an inner pressure plate 770. A first elastic member 771 is connected between the inner pressure plate and the upper template, and a second pad 780 is also attached to the bottom surface of the inner pressure plate; an annular outer pressure plate 790 is movably provided on the outer side of the annular cutter, and a second elastic member 791 is connected between the outer pressure plate and the cutter positioning frame. A blade accommodating groove for accommodating the annular cutter is formed between the inner side wall of the outer pressure plate and the outer side wall of the inner pressure plate. The outer pressure plate and the inner pressure plate can be reset downward under the rebound action of the second elastic member and the first elastic member until the annular cutter is retracted into the blade accommodating groove as a whole;

[0043] See Figure 2 The jig includes a lower template 210 and a punch 220 arranged on the upper side of the lower template. A lower recess 230 is provided in the middle of the upper surface of the punch. The contour of the lower recess matches the raised part of the surface paper. A third pad 240 is attached to the upper surface of the punch. The outer contour of the third pad is adapted to the inner contour of the annular cutter.

[0044] The operating principle of the trimming and pressing assembly is as follows: the hydraulic press pushes the upper mold assembly downward and approaches the jig below. The outer pressure plate and the second pad first contact the bottom paper and press the edge parts of the surface paper and the bottom paper onto the third pad. The raised parts of the foam board and the surface paper are also completely pushed into the lower recess and abut against the bottom of the lower recess. As the upper mold assembly continues to press downward, the elastic force applied to the outer pressure plate and the inner pressure plate by the second elastic member and the first elastic member continues to increase. The pressure of the outer pressure plate is used to keep the outer edge of the paper straight to avoid wrinkles during the trimming process. The pressure of the inner pressure plate is used to increase the pressure on the pasting part. The greater the pressure, the smoother the pasting. The more solid it is; during this process, the annular cutter in the blade receiving groove gradually extends out and cuts the top paper and the bottom paper until the annular cutter contacts the third pad. At this time, the trimming process is completed, but it is generally necessary to maintain this state for a few seconds to increase the adhesion strength between the papers; then the hydraulic press pulls the upper mold assembly upward to reset. Initially, the outer pressure plate and the inner pressure plate remain fixed under the rebound action of the elastic member, and the annular cutter begins to gradually retract into the blade receiving groove, so as to ensure that the cake base and the waste edges will not be stuck on the annular cutter. Then the outer pressure plate and the inner pressure plate leave the cake base, and the cake base and the waste edges remain on the jig. In this embodiment, the jig mainly plays the role of transportation, positioning the top paper, and serving as the lower mold in the trimming and pressing station.

[0045] This embodiment includes five stations: a surface paper loading station, a foam board loading station, a bottom paper loading station, a trimming and pressing station, and a bottom support unloading station. The surface paper loading station uses a suction cup transport assembly to grab and transport the already formed surface paper to the jig in the station; the foam board loading station uses a gripping and clamping transport assembly to grab and transport the foam board to the surface paper in the station, and ensure that the foam board is completely or partially stuffed into the concave cavity of the surface paper; the bottom paper loading station uses a suction cup transport assembly to grab and transport the bottom paper that has been coated with glue to the foam board in the station, and ensure that the bottom paper and the surface paper are basically facing each other; the trimming and pressing station uses a trimming and pressing assembly to press and trim the material on the jig; the bottom support unloading station uses a suction cup transport assembly to suck away the bottom support and waste edges together to complete the unloading. The formed surface paper, foam board and glue-brushed bottom paper used in this embodiment can all be automatically fed by existing equipment.

[0046] The circulating transport mechanism operates as follows: Initially, the upper mold lift assembly is in the high position, with a jig on its corresponding lift platform; the lower mold lift assembly is in the high position, with its corresponding lift platform empty; and each of the two chutes contains three jigs. Upon startup, the first pusher pushes the jig on the upper mold lift assembly into the first chute, resets it, and pushes the jig at the rear end of the first chute onto the lift platform of the lower mold lift assembly. Both mold lift assemblies then lower their corresponding lift platforms to the low position. The second pusher pushes the jig on the lower mold lift assembly into the second chute, resets it, and pushes the jig at the front end of the second chute onto the lift platform of the upper mold lift assembly. The two mold lift assemblies then push their corresponding lift platforms back to the high position, beginning the next cycle. This allows each jig to move in sequence, from the top paper loading station, to the foam board loading station, to the backing paper loading station, to the trimming and laminating station, and finally to the bottom support unloading station. The interval between the two pushers' movements is determined by the processing time of the slowest processing station.

[0047] In summary, the production actions of this embodiment are as follows: the suction cup conveying assembly on the surface paper loading station can convey the surface paper on the surface paper supply device or station to the jig in the surface paper loading station, and then the jig is driven by the circular transmission device to move backward to the foam board loading station, the clamping conveying assembly can convey the foam board on the foam board supply device or station to the jig, and make the foam board embedded in the surface paper, and then the jig is driven by the circular transmission device to move backward to the bottom paper loading station, the suction cup conveying assembly can convey the bottom paper on the bottom paper supply device or station to the jig, and make the glue side face down to cover the foam board, and then the jig is driven by the circular transmission device to move backward to the trimming and pressing station, and finally moves to the bottom support unloading station after completing the trimming and pressing, and the tray and waste edges are moved away by the suction cup conveying assembly.

[0048] See Figure 11 and Figure 12 , 8 guide grooves 751 are provided in the cutter positioning frame, 8 guide blocks 792 that slide in conjunction with the guide grooves are fixed to the upper side of the outer pressure plate, and step screws that pass through the first pad are connected between some of the guide blocks and the upper template. The second elastic member is arranged in the guide groove and abuts against the top of the guide block; an upwardly protruding guide protrusion 772 is provided on the upper side of the inner pressure plate, and an inner guide groove that slides in conjunction with the guide protrusion is provided on the bottom surface of the upper template. 8 step screws are also connected between the inner pressure plate and the upper template. An upper air vent 773 that also passes through the second pad is provided on the inner pressure plate, and a lower air vent 250 is provided at the bottom of the lower recess. Both the upper and lower air vents are used to stabilize the air pressure on the upper and lower surfaces of the cake tray to avoid adsorption during demolding.

[0049] See Figure 13 The suction cup transport assembly includes a horizontal servo slide assembly 510, a lifting cylinder 520 driven to move back and forth by the horizontal servo slide assembly, a lifting plate 530 driven to rise and fall by the lifting cylinder, and a plurality of suction cups 540 arranged on the lifting plate, and the suction cups are arranged vertically downward.

Each clamping cylinder is provided with a clamping piece 620. The four clamping pieces enclose a rectangular clamping cavity. The clamping piece is driven to move by the extension and retraction of the clamping cylinder to expand or shrink the clamping cavity.

[0051] See Figure 5 , a positioning cylinder 10 is provided on the mounting base and on the side of the first chute. The axis of the cylinder rod of the positioning cylinder is perpendicular to the first chute. A top block 11 is provided on the cylinder rod. The top block can fix the jig against the side wall of the first chute. When the two propulsion devices are in standby mode, the jig in the first chute is in a stationary state. This stage corresponds to the loading and unloading and processing stages of the products to be processed on the jig at the corresponding workstations. Therefore, it is necessary to ensure that each jig is docked in a preset position. For this purpose, a positioning cylinder is provided for the jig on each workstation. When the jig is in a stationary state, the positioning cylinder will be ejected, and the top block on it will fix the jig against the side wall of the first chute. At the same time, the top block cooperates with the positioning groove on the jig, so that the jig is completely fixed and precisely positioned.

[0052] See Figure 3 and Figure 5The front end of the mounting base is provided with a front buffer cylinder 20, and its cylinder rod is provided with an abutment block 21 facing the jig from the second slide; the rear end of the mounting base is provided with a rear buffer cylinder 30, and its cylinder rod is provided with an abutment block 2 facing the jig from the first slide. The abutment block is made of rubber or plastic. Both track change windows are provided with structures for limiting the jig. The corresponding buffer cylinder needs to extend the abutment block in advance before the corresponding propulsion device is activated. In this way, when the propulsion device pushes the jig out, the jig will first contact the abutment block and continue to compress the buffer cylinder. This can slow down the jig in advance and reduce the impact force between the jig and the rear limiter and the front limiter, which is beneficial to reducing the vibration and impact noise of the entire equipment and can effectively improve the material life of the impact part.
