Description

Technical Field

[0001] The utility model relates to a cake bottom production device, in particular to an automatic cake bottom production device. Background Art

[0002] A cake bottom is a base for supporting a cake body. The structure of the cake bottom includes a bottom paper 1, a foam board 2, and a surface paper 3. The size of the foam board is slightly smaller than that of the bottom paper. The foam board is located above the bottom paper. The surface paper needs to be processed to form a cavity inside that can accommodate the foam board. Then, the surface paper completely wraps the foam board and fits and fixes to the edge of the bottom paper, so that the shape of the cake bottom is in a "dish" shape (refer to the appendix Figure 1 ). The outlines of the bottom mainly include two types: circular and square. During the production of the cake bottom, the bottom paper, the foam board, and the surface paper need to be stacked in sequence and adhesively fixed to each other with glue.

[0003] Previously, the production of the bottom was carried out by a combination of manual and semi-automatic equipment, which not only had low production efficiency and low yield rate, but also led to high production costs. Later, the production process of the cake bottom was split into multiple sub-processes, and equipment that could automatically complete the process was developed accordingly. For example, a gluing device for gluing the bottom paper, a surface paper forming device for stretching and forming the surface paper, a pressing device for pressing the bottom paper, the foam board, and the surface paper together, and a trimming device for trimming the semi-finished product after pressing and forming. This can greatly improve the production efficiency of each sub-process and improve quality control. However, this also requires a lot of labor to transfer semi-finished products and raw materials.

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

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

[0006] The above technical problem of the utility model is mainly solved by the following technical solution: An automatic cake bottom production device, characterized by comprising:

[0007] Circular transfer device, the circular transfer device includes: a mounting substrate, which is horizontally and fixedly arranged, and has a first chute evenly distributed in the length direction on its upper surface, and a second chute parallel and opposite to the first chute is arranged at the bottom of the mounting substrate; two track-changing windows, which are formed through the mounting substrate and are located at the front and rear ends of the first chute; two mold lifting assemblies, including a lifting module and a lifting platform driven by it, the two mold lifting assemblies are respectively arranged at the bottoms of the two track-changing windows, and are correspondingly set as an upward mold lifting assembly and a downward mold lifting assembly, and the lifting module can drive the lifting platform to reciprocally switch between the heights where the two chutes are located; 7 fixtures, 3 pieces are slidably assembled in each of the first chute and the second chute, and the remaining one is located on any lifting platform; two pushing devices, which are divided into a first pushing device arranged at the front end of the mounting substrate and facing backward and a second pushing device arranged at the rear end of the mounting substrate and facing forward, the area of the track-changing window at the front end corresponds to the paper feeding station, the position of the first fixture in the first chute corresponds to the foam board feeding station, the position of the second fixture in the first chute corresponds to the bottom paper feeding station, the position of the third fixture in the first chute corresponds to the trimming and pressing station, and the area of the track-changing window at the rear end corresponds to the bottom plate discharging station;

[0008] Three sets of suction cup handling components, which are respectively arranged above the paper feeding station, the bottom paper feeding station and the bottom plate discharging station;

[0009] One set of gripper handling component, which is arranged above the foam board feeding station;

[0010] One set of trimming and pressing component, which is arranged above the trimming and pressing station.

[0011] Furthermore, the trimming and pressing component includes a plurality of guide columns vertically fixed above the trimming and pressing station, a hydraulic press fixed at the upper ends of the guide columns, and an upper die component slidably sleeved on the guide columns. The upper die component includes an upper template, a first backing plate attached to the bottom surface of the upper template, a cutter positioning frame fixed under the first backing plate, and an annular cutter fixed on the cutter positioning frame. The cutting edge of the annular cutter is vertically downward, and an inner pressing plate is movably arranged in the internal area defined by the annular cutter. A first elastic member is connected between the inner pressing plate and the upper template, and a second backing plate is also attached to the bottom surface of the inner pressing plate; an annular outer pressing plate is movably arranged outside the annular cutter, a second elastic member is connected between the outer pressing 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 pressing plate and the outer side wall of the inner pressing plate. The outer pressing plate and the inner pressing plate can be reset downward under the rebounding action of the second elastic member and the first elastic member until the whole annular cutter retracts into the blade accommodating groove;

[0012] The fixture includes a lower template and a punch provided on the upper side of the lower template. A concave portion is provided in the middle of the upper surface of the punch, and the contour of the concave portion matches the raised portion of the cover paper. A third backing plate is attached to the upper surface of the punch, and the outer contour of the third backing plate is adapted to the inner contour of the ring cutter.

[0013] The operating principle of the edge cutting and pressing assembly is as follows: The hydraulic press pushes the upper die assembly downward to approach the fixture below. The outer pressure plate and the second backing plate first contact the bottom paper and press the edge portions of the cover paper and the bottom paper onto the third backing plate. The foam board and the raised portion of the cover paper are also completely pushed into the concave portion and abut against the bottom of the concave portion. As the upper die assembly continues to press downward, the elastic forces exerted by the second elastic member and the first elastic member on the outer pressure plate and the inner pressure plate also continuously increase. The pressure of the outer pressure plate is used to keep the outer edge of the paper straight and avoid wrinkles during the edge cutting process. The pressure of the inner pressure plate is used to increase the pressure at the pasting portion. The greater the pressure, the firmer the pasting. During this process, the ring cutter in the blade accommodating groove gradually extends and cuts the cover paper and the bottom paper until the ring cutter abuts against the third backing plate. At this time, the edge cutting process is completed, but generally this state needs to be maintained for a few seconds to increase the adhesion firmness between the papers. Then the hydraulic press pulls the upper die assembly upward to reset. Initially, the outer pressure plate and the inner pressure plate remain fixed under the action of the elastic rebound of the elastic members, and the ring cutter begins to gradually retract into the blade accommodating groove, which can ensure that the cake bottom and the waste edge will not get stuck on the ring cutter. Then the outer pressure plate and the inner pressure plate leave the cake bottom, and at this time the cake bottom and the waste edge remain on the fixture. The fixture mainly functions as a transporter, a cover paper positioner, and a lower die in the edge cutting and pressing station in the present utility model.

[0014] The present utility model includes five stations: a cover paper feeding station, a foam board feeding station, a bottom paper feeding station, an edge cutting and pressing station, and a bottom discharging station. Among them, at the cover paper feeding station, the formed cover paper is grabbed and transported to the fixture in this station by the suction cup handling assembly; at the foam board feeding station, the foam board is grabbed and transported to the cover paper in this station by the gripper handling assembly, and it is ensured that the foam board is completely or partially inserted into the concave cavity of the cover paper; at the bottom paper feeding station, the bottom paper coated with glue is grabbed and transported to the foam board in this station by the suction cup handling assembly, and it is ensured that the bottom paper is basically aligned with the cover paper; at the edge cutting and pressing station, the edge cutting and pressing assembly presses and cuts the materials on the fixture; at the bottom discharging station, the bottom and the waste edge are sucked away together by the suction cup handling assembly to complete the discharging. The formed cover paper, foam board, and bottom paper coated with glue used in the present utility model can all be automatically fed by existing equipment.

[0015] The operating mode of the cyclic transmission device is as follows: The initial state is set such that the upper die lifting assembly is at the high position, and a fixture is carried on its corresponding lifting platform. The lower die lifting assembly is at the high position, and its corresponding lifting platform is in the no-load state. There are 3 fixtures distributed on each of the two chutes. After starting the operation, the first propulsion device pushes the fixture on the upper die lifting assembly into the first chute and then resets. The fixture originally at the rear end of the first chute is pushed onto the lifting platform of the lower die lifting assembly. Then, the two die lifting assemblies lower the corresponding two lifting platforms to the low position. Then, the second propulsion device pushes the fixture on the lower die lifting assembly into the second chute and then resets. The fixture originally at the front end of the second chute is pushed onto the lifting platform of the upper die lifting assembly. Then, the two die lifting assemblies push the corresponding two lifting platforms to the high position again to perform the next round of cycle. In this way, each fixture can move at intervals along the order of the paper feeding station, the foam board feeding station, the bottom paper feeding station, the trimming and pressing station, and the bottom discharging station. The action interval of the two propulsion devices is determined by the time consumed by the slowest processing station.

[0016] Further, the sucker handling assembly includes a horizontal servo sliding table assembly, a lifting cylinder driven by the horizontal servo sliding table assembly to reciprocate, a lifting plate driven by the lifting cylinder to lift, and a plurality of suckers provided on the lifting plate. The suckers are arranged vertically downward.

[0017] Further, the gripper handling assembly includes a horizontal servo sliding table assembly, a lifting cylinder driven by the horizontal servo sliding table assembly to reciprocate, a lifting plate driven by the lifting cylinder to lift, and four clamping cylinders provided on the lifting plate. A clamping piece is provided on each clamping cylinder. The 4 clamping pieces enclose a rectangular clamping cavity. The clamping cavity is enlarged or reduced by driving the clamping pieces to move through the telescopic movement of the clamping cylinders.

[0018] Further, a positioning cylinder is provided on the mounting substrate and on the side of the first chute. The axial direction of the cylinder rod of the positioning cylinder is perpendicular to the first chute. A top block is provided on the cylinder rod. The top block can press and fix the fixture against the side wall of the first chute. When the two propulsion devices are in the standby state, the fixtures in the first chute are in a static state. This stage corresponds to the feeding, discharging, and processing stages of the products to be processed on the fixtures at the corresponding stations. Therefore, it is necessary to ensure that each fixture stops at a preset position. For this purpose, a positioning cylinder is provided corresponding to each fixture at each station. When the fixture is in a static state, the positioning cylinder will eject, and the top block on it will press and fix the fixture against the side wall of the first chute. At the same time, the top block cooperates with the positioning groove on the fixture, so that the fixture is completely fixed and accurately positioned.

[0019] Further, a front buffer cylinder is provided at the front end of the mounting substrate, and a first abutting block facing the fixture from the second chute is provided on its cylinder rod; a rear buffer cylinder is provided at the rear end of the mounting substrate, and a second abutting block facing the fixture from the first chute is provided on its cylinder rod. The material of the abutting block is rubber or plastic. Structures for limiting the fixture are provided in both rail-changing windows. The corresponding buffer cylinder needs to extend the abutting block in advance before the corresponding propulsion device operates. In this way, when the propulsion device pushes out the fixture, the fixture will first contact the abutting block and continue to compress the buffer cylinder, which can reduce the speed of the fixture in advance and reduce the impact force of the fixture against the rear limiting member and the front limiting member, which is beneficial to reducing the vibration and impact noise of the entire device and can effectively improve the material life of the impact part.

[0020] Therefore, the present utility model has the following characteristics compared with the prior art: 1. The present utility model includes five workstations: a front paper feeding workstation, a foam board feeding workstation, a bottom paper feeding workstation, a trimming and pressing workstation, and a bottom tray discharging workstation, and the five workstations are connected in series through a circulating transmission device. The circulating transmission device has the function of circulating and conveying the fixture. The front paper feeding workstation, the foam board feeding workstation, and the bottom paper feeding workstation on the present utility model can be combined with existing equipment to realize the full automation production of trays; 2. The trimming and pressing assembly has the function of bonding and trimming the bottom paper, the foam board, and the front paper. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Embodiment 1: See Figure 3 , an automated production equipment for cake bottoms, including:

[0038] A cyclic transmission device (see Figure 4 , Figure 8 and Figure 10 ), the cyclic transmission device includes: a mounting substrate 100, which is horizontally and fixedly arranged, and two parallel and spaced upper retaining bars 110 are provided on the upper surface of the mounting substrate. A first chute 101 is defined between the two upper retaining bars and the upper surface of the mounting substrate; two parallel and spaced lower retaining bars 120 are provided on the lower surface of the mounting substrate, and a support plate 130 is provided at the bottom of the lower retaining bars. A second chute 102 is defined between the two upper retaining bars and the upper surface of the support plate, and the two chutes are vertically aligned (see Figure 7 ); two track-changing windows 140 (see Figure 5 and Figure 6) that penetrate through and are formed on the mounting substrate and located at the front and rear ends of the first chute; two mold lifting assemblies 300, including a lifting module 310 and a lifting platform 320 driven by it; the lifting module includes a cylinder seat 311 fixed to the lower side of the mounting substrate, a lifting cylinder 312 vertically fixed to the cylinder seat, several linear bearings 313 vertically fixed to the cylinder seat, and a lifting column 314 slidably assembled in the linear bearings. The piston rod of the lifting cylinder and the lifting column are both fixedly connected to the bottom of the lifting platform (see Figure 9 ); both lifting platforms can carry the remaining one fixture. The two mold lifting assemblies are respectively arranged at the bottoms of the two rail-changing windows, and are correspondingly set as the upward mold lifting assembly 301 and the downward mold lifting assembly 302. The lifting module can drive the lifting platform to reciprocally switch between the heights where the two chutes are located; 7 fixtures 200, with 3 slidably assembled in each of the first chute and the second chute, and the remaining one is located on any lifting platform; two pushing devices 400, specifically long cylinders, with a pushing part 410 made of rubber or plastic at the end of the piston rod, are divided into a first pushing device 401 arranged at the front end of the mounting substrate and facing backward and a second pushing device 402 arranged at the rear end of the mounting substrate and facing forward. The first pushing device can push the fixture on the upward mold lifting assembly into the first chute, and the second pushing device can push the fixture on the downward mold lifting assembly into the second chute; the rail-changing window area at the front end corresponds to the surface paper loading station, the position of the first fixture in the first chute corresponds to the foam board loading station, the position of the second fixture in the first chute corresponds to the bottom paper loading station, the position of the third fixture in the first chute corresponds to the trimming and pressing station, and the rail-changing window area at the rear end corresponds to the bottom plate unloading station;

[0039] Three sets of suction cup handling assemblies 500 are respectively arranged above the surface paper loading station, the bottom paper loading station, and the bottom plate unloading station;

[0040] One set of gripper handling assembly 600 is arranged above the foam board loading station;

[0041] One set of trimming and pressing assembly 700 is arranged above the trimming and pressing station.

[0042] See Figure 3 、 Figure 11 and Figure 12, the trimming and pressing assembly includes four guide columns 710 vertically fixed above the trimming and pressing station, a hydraulic press 720 fixed to the upper ends of the guide columns, and an upper die assembly slidably sleeved on the guide columns. The upper die assembly includes an upper template 730, a first backing plate 740 attached to the bottom surface of the upper template, a cutter positioning frame 750 fixed to the lower side of the first backing plate, and an annular cutter 760 fixed to the cutter positioning frame. The cutting edge of the annular cutter is vertically downward. An inner pressing plate 770 is movably arranged in the inner region defined by the annular cutter. A first elastic member 771 is connected between the inner pressing plate and the upper template. A second backing plate 780 is also attached to the bottom surface of the inner pressing plate; an annular outer pressing plate 790 is movably arranged outside the annular cutter. A second elastic member 791 is connected between the outer pressing plate and the cutter positioning frame. A blade accommodating groove for the annular cutter is formed between the inner side wall of the outer pressing plate and the outer side wall of the inner pressing plate. The outer pressing plate and the inner pressing plate can be reset downward under the elastic return of the second elastic member and the first elastic member until the whole annular cutter retracts into the blade accommodating groove;

[0043] See Figure 2 , the fixture includes a lower template 210 and a punch 220 arranged above the lower template. A concave portion 230 is provided in the middle of the upper surface of the punch. The contour of the concave portion matches the raised portion of the cover paper. A third backing plate 240 is attached to the upper surface of the punch. The outer contour of the third backing plate 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 die assembly downward to approach the lower fixture. The outer pressing plate and the second backing plate first contact the bottom paper and press the edge parts of the cover paper and the bottom paper on the third backing plate. The foam board and the raised portion of the cover paper are also completely pushed into the concave portion and abut against the bottom of the concave portion. As the upper die assembly continues to press downward, the elastic forces exerted by the second elastic member and the first elastic member on the outer pressing plate and the inner pressing plate also continuously increase. The pressure of the outer pressing plate is used to keep the outer edge of the paper straight and avoid wrinkles during the trimming process. The pressure of the inner pressing plate is used to increase the pressure at the pasting part. The greater the pressure, the firmer the pasting; during this process, the annular cutter in the blade accommodating groove gradually extends and cuts the cover paper and the bottom paper until the annular cutter abuts against the third backing plate. At this time, the trimming process is completed, but generally this state needs to be maintained for a few seconds to increase the adhesion firmness between the papers; then the hydraulic press pulls the upper die assembly upward to reset. At first, the outer pressing plate and the inner pressing plate remain fixed under the elastic return of the elastic members, and the annular cutter begins to gradually retract into the blade accommodating groove, which can ensure that the cake bottom and the waste edge will not get stuck on the annular cutter, and then the outer pressing plate and the inner pressing plate leave the cake bottom. At this time, the cake bottom and the waste edge remain on the fixture. The fixture mainly functions as a transporter, a cover paper positioner, and a lower die in the trimming and pressing station in this embodiment.

[0045] This embodiment includes five workstations: the paper feeding station, the foam board feeding station, the bottom paper feeding station, the trimming and pressing station, and the bottom plate discharging station. Among them, at the paper feeding station, the suction cup handling component grabs and transports the formed paper to the fixture within this station; at the foam board feeding station, the gripper handling component grabs and transports the foam board to the paper within this station, and ensures that the foam board is completely or partially inserted into the concave cavity of the paper; at the bottom paper feeding station, the suction cup handling component grabs and transports the bottom paper coated with glue to the foam board within this station, and ensures that the bottom paper is basically aligned with the paper; at the trimming and pressing station, the trimming and pressing component presses and trims the materials on the fixture; at the bottom plate discharging station, the suction cup handling component sucks away the bottom plate and waste edges together to complete the discharging. The formed paper, foam board, and bottom paper with glue used in this embodiment can all be automatically fed by existing equipment.

[0046] The operation mode of the circulating transmission device is as follows: The initial state is set such that the upward die lifting component is at the high position, and a fixture is carried on its corresponding lifting platform. The downward die lifting component is at the high position, and its corresponding lifting platform is in the unloaded state. There are 3 fixtures distributed on each of the two chutes. After starting to run, the first propulsion device pushes the fixture on the upward die lifting component into the first chute and then resets. The fixture originally at the rear end of the first chute is pushed onto the lifting platform of the downward die lifting component. Then, the two die lifting components lower the corresponding two lifting platforms to the low position. Then, the second propulsion device pushes the fixture on the downward die lifting component into the second chute and then resets. The fixture originally at the front end of the second chute is pushed onto the lifting platform of the upward die lifting component. Then, the two die lifting components push the corresponding two lifting platforms to the high position again for the next round of cycle. In this way, each fixture can move at intervals along the sequence of the paper feeding station, the foam board feeding station, the bottom paper feeding station, the trimming and pressing station, and the bottom plate discharging station. The action interval of the two propulsion devices is determined by the time consumed by the slowest processing station.

[0047] In summary, the production actions of this embodiment are as follows: The suction cup handling component at the paper feeding station can transport the paper from the paper supply equipment or station to the fixture within the paper feeding station. Then, this fixture is driven by the circulating transmission device to move backward to the foam board feeding station. The gripper handling component can transport the foam board from the foam board supply equipment or station to this fixture, and make the foam board embed into the paper. Then, this fixture is driven by the circulating transmission device to move backward to the bottom paper feeding station. The suction cup handling component can transport the bottom paper from the bottom paper supply equipment or station to this fixture, and make the side with glue face down to cover the foam board. Then, this fixture is driven by the circulating transmission device to move backward to the trimming and pressing station. After completing the trimming and pressing, it finally moves to the bottom plate discharging station, and the bottom plate and waste edges are carried away by the suction cup handling component.

[0048] SeeFigure 11 and Figure 12 Inside the cutter positioning frame, there are 8 guiding grooves 751. On the upper side of the outer pressure plate, 8 guiding blocks 792 that are slidably engaged with the guiding grooves are fixed. Some of the guiding blocks are connected to the upper template by stepped screws that penetrate the first backing plate. A second elastic member is arranged in the guiding groove and abuts against the top of the guiding block; on the upper side of the inner pressure plate, there is an upward protruding guiding protrusion 772, and on the bottom surface of the upper template, there is an inner guiding groove that is slidably engaged with the guiding protrusion. There are also 8 stepped screws connecting the inner pressure plate and the upper template. An upper ventilation hole 773 that penetrates through the second backing plate is provided through the inner pressure plate. At the bottom of the concave portion, there is a lower ventilation hole 250. Both the upper ventilation hole and the lower ventilation hole are used to stabilize the air pressure on the upper and lower surfaces of the cake bottom, avoiding the adsorption effect during demolding.

[0049] See Figure 13 As shown, the sucker handling assembly includes a horizontal servo sliding table assembly 510, a lifting cylinder 520 driven by the horizontal servo sliding table assembly to reciprocate, a lifting plate 530 driven by the lifting cylinder to move up and down, and a number of suckers 540 arranged on the lifting plate. The suckers are arranged vertically downward.

[0050] See Figure 14 As shown, the gripper handling assembly includes a horizontal servo sliding table assembly 510, a lifting cylinder 520 driven by the horizontal servo sliding table assembly to reciprocate, a lifting plate 530 driven by the lifting cylinder to move up and down, and four clamping cylinders 610 arranged on the lifting plate. Each clamping cylinder is provided with a clamping piece 620. The 4 clamping pieces enclose a rectangular clamping cavity, and the clamping cavity is enlarged or reduced by driving the clamping pieces to move through the telescopic movement of the clamping cylinder.

[0051] See Figure 5 On the mounting substrate and on the side of the first chute, there is a positioning cylinder 10. The axial direction of the cylinder rod of the positioning cylinder is perpendicular to the first chute. A top block 11 is arranged on the cylinder rod, and the top block can press and fix the jig against the side wall of the first chute. When the two propulsion devices are in the standby state, the jig in the first chute is in a static state. This stage corresponds to the feeding, discharging, 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 stops at the preset position. For this reason, each workstation's jig is correspondingly provided with a positioning cylinder. When the jig is in a static state, the positioning cylinder will eject, and the top block on it will press and 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 accurately positioned.

[0052] See Figure 3 and Figure 5, a front-end buffer cylinder 20 is provided at the front end of the mounting substrate, and a first abutting block 21 facing the fixture from the second chute is provided on its cylinder rod; a rear-end buffer cylinder 30 is provided at the rear end of the mounting substrate, and a second abutting block facing the fixture from the first chute is provided on its cylinder rod. The material of the abutting block is rubber or plastic. Structures for limiting the fixture are provided in both rail-changing windows. The corresponding buffer cylinder needs to extend the abutting block in advance before the corresponding propulsion device operates. In this way, when the propulsion device pushes out the fixture, the fixture will first contact the abutting block and continue to compress the buffer cylinder, which can reduce the speed of the fixture in advance and reduce the impact force between the fixture and the rear limiting member and the front limiting member. This is beneficial to reducing the vibration and impact noise of the entire device and can effectively improve the material life of the impact part.

[0053] It will be obvious to those skilled in the art that the present utility model can be changed in various ways, and such changes are not considered to depart from the scope of the present utility model. All such modifications obvious to those skilled in the art will be included within the scope of the present claims.
