Description

Technical Field

[0001] The present invention relates to the technical field of bottom tray machines, and particularly relates to a fully automatic cake box bottom tray machine and its usage method. Background Art

[0002] The traditional method for cake box bottom trays is as follows: manually fold the die-cut paper, put it into a standard sleeve mold, add filling material, and then cover it with cardboard; stack the filled bottom trays and sleeve molds together and press them tightly with heavy pressure; take out the semi-finished bottom trays; put the semi-finished bottom trays into a die-cutting machine to cut off the surrounding and anti-slip notches. This traditional method not only has low efficiency, high labor cost, but also occupies more production space and is not convenient for large-scale production. Although there are now machines for producing bottom trays, manual operation is still required to put materials into the machine. After the machine completes a certain step, another material needs to be put in manually and processed in sequence, resulting in low production efficiency. At the same time, during the production process involving personnel, there is a risk of pinching, which poses a certain threat to the safety of personnel.

[0003] Therefore, there is an urgent need for a fully automatic production and processing machine for cake box bottom trays with high production efficiency and safe use. Summary of the Invention

[0189] 2. The cardboard A is pressed into semi-finished product A2, and the second station rotates to the third station;

[0190] 3. The raw material foam board B is conveyed by the feeding machine into the semi-finished product A2 to become semi-finished product B1, and the third station rotates to the fourth station;

[0191] 4. The raw material cardboard C is coated with glue by the gluing machine 7 and conveyed into the semi-finished product B1 to form semi-finished product C1, and the fourth station rotates to the fifth station;

[0192] 5. The semi-finished product C1 is compacted to firmly bond the glued edge of the cardboard C to the outer edge of the semi-finished product B1, and the fifth station rotates to the sixth station;

[0193] 6. The semi-finished product C1 is trimmed to form the finished product K, and the unloading machine 6 sends the finished product K to the receiving machine 8.

[0194] The specific steps include:

[0195] I. Checking before starting up:

[0196] Start the reducer motor 3-8, and the six-station cam divider 3-5 rotates the rotary table 3-73 to check that the upper dies 3-1-1 at each station are correctly closed with the lower dies;

[0197] Start each driving machine 3-100 to make the feeding machine 4 feed materials from each stock preparation machine to the correct positions at each station without error.

[0198] II. Operating the electricity and signals to each actuator

[0199] 1. As Figure 2 shown, after the raw material cardboard A is angled by the cornering machine 2, it is placed at the first station, and the first station rotates to the second station;

[0200] Place the cardboard A, foam board B, and cardboard C at the designated positions of the first stock preparation machine 1, the second stock preparation machine 5, and the third stock preparation machine 9 respectively;

[0201] Start the driving machine 3-100 at the first station. The feeding machine 4 at the first station moves to directly above the cardboard A at the first stock preparation machine 1 and sucks up the cardboard A. Then the feeding machine 4 moves the cardboard A to the cornering station of the cornering machine 2. The cornering machine 2 angles the cardboard A to form a semi-finished cardboard. The feeding machine 4 at the first station continues to move, moves the semi-finished cardboard to the lower die at the first station and then returns. The feeding machine 4 at the first station resets to directly above the cardboard A at the first stock preparation machine 1 and repeats the next working process;

[0202] The reducer motor 3-8 operates, and the six-station cam divider 3-5 rotates the rotary table 3-73 clockwise by 60°, so that the lower die with the semi-finished cardboard at the first station rotates to the second station;

[0203] 2. As Figure 3As shown, cardboard A is pressed into semi-finished product A2, and station two rotates to station three;

[0204] The oil cylinder 3-1-4 at station two acts, pushing the dovetail slider 3-1-2 to make the upper die 3-1-1 descend to close the die with the lower die, pressing the semi-finished cardboard into semi-finished product A2. The upper die 3-1-1 resets and waits for the next working process. At the same time, the feeding machine 4 at station one completes one working process;

[0205] The reduction gear motor 3-8 acts, and the six-station cam divider 3-5 rotates the rotary platform 3-73 clockwise by 60°, so that the lower die with semi-finished product A2 at station two rotates to station three. At the same time, the lower die with semi-finished product A1 at station one rotates to station two.

[0206] 3. As Figure 4 shown, the raw material foam board B is conveyed by the feeding machine and sent into semi-finished product A2 to become semi-finished product B1, and station three rotates to station four;

[0207] The drive machine 3-100 at station three starts. The feeding machine 4 at station three moves to directly above the foam board B of the second stock preparation machine 5, sucks up the foam board B, sends it to the lower die at station three, and sends it into semi-finished product A2 to form semi-finished product B1. The feeding machine 42 returns to directly above the foam board B of the second stock preparation machine 5 and repeats the next working process; at the same time, one working process is completed at each of station one and station two;

[0208] The reduction gear motor 3-8 acts, and the six-station cam divider 3-5 rotates the rotary platform 3-73 clockwise by 60°, so that the lower die with semi-finished product B1 at station three rotates to station four. At the same time, the semi-finished products in the lower dies of station one and station two follow in sequence;

[0209] 4. As Figure 2 shown, the raw material cardboard C is coated with glue by the gluing machine 7 and conveyed into semi-finished product B1 to form semi-finished product C1, and station four rotates to station five;

[0210] The drive machine 3-100 at station four starts. The feeding machine 4 at station four moves to directly above the cardboard C of the third stock preparation machine 9, sucks up the cardboard C and sends it to the gluing station of the gluing machine 7. After the gluing machine 7 coats the two opposite edges of the lower plane of the cardboard C with glue, the feeding machine 4 acts, and the cardboard C rises. The feeding machine 4 rotates the cardboard C horizontally by 90°. The cardboard C then descends to the gluing station of the gluing machine 7 to coat the other two opposite edges of the lower plane of the cardboard C with glue. The feeding machine 4 acts to move the cardboard C to directly above station 4 and presses the cardboard C on semi-finished product B1 to form semi-finished product C1; the feeding machine 4 resets to directly above the cardboard C of the third stock preparation machine 9 and repeats the next working process; at the same time, the semi-finished products in the lower dies of station one, station two, and station three follow in sequence;

[0211] The reduction motor 3-8 operates, and the six-station cam divider 3-5 rotates the rotary table 3-73 clockwise by 60°, causing the lower die with the semi-finished product C1 at station four to rotate to station five, and the other stations follow in sequence;

[0212] 5. As Figure 3 shown, compact the semi-finished product C1 to firmly bond the glued edge of the cardboard C to the outer edge of the semi-finished product B1, and station five rotates to station six;

[0213] The oil cylinder 3-1-4 at station five operates, pushing the dovetail slider 3-1-2 to lower the upper die 3-1-1 to close the die with the lower die, compact the semi-finished product C1, and firmly bond the glued edge of the cardboard C to the outer edge of the semi-finished product B1. Then the upper die 3-1-1 resets, waiting for the next working process. At the same time, one working process is completed at each of stations one, two, three, and four;

[0214] The reduction motor 3-8 operates, and the six-station cam divider 3-5 rotates the rotary table 3-73 clockwise by 60°, causing the lower die with the semi-finished product C1 at station five to rotate to station six, and the other stations follow in sequence;

[0215] 6. As Figure 4 shown, trim the semi-finished product C1 to make it into the finished product K, and the unloader 6 sends the finished product K to the receiving machine 8;

[0216] The oil cylinder 3-1-4 at station six operates, pushing the dovetail slider 3-1-2 to lower the upper die 3-1-1 integrated with the blade 6-1-1-0 to close the die with the lower die, trim the semi-finished product C1 to make it into the finished product K. Then the upper die 3-1-1 resets, waiting for the next working process. At the same time, one working process is completed at each of stations one, two, three, four, and five;

[0217] The unloader 6 operates, sucking and lifting the finished product K. At the same time, the ejector mechanism 6-1-50 operates, and the ejector pin 6-1-50-6 lifts the ejector plate 6-1-50-8. The ejector plate 6-1-50-8 follows the movement of the unloader 6 to lift the finished product K. The unloader 6 sends the finished product K above the receiving machine 8, releases the finished product K and it falls into the receiving frame 8-1-2. The unloader 6 resets, waiting for the next working process. The entire mechanism completes one working process of the finished product K. Continuously repeating the above process can continuously produce the finished product K.

[0218] When the finished product K in the receiving frame 8-1-2 reaches a certain height, the receiving cylinder 8-1-5 operates, and the receiving working shaft 8-1-4 and the receiving push plate 8-1-3 push the receiving frame 8-1-2 along the receiving guide rail 8-1-1 to move the finished product K outwards, leaving a receiving space, and then the receiving cylinder 8-1-5 resets.

[0219] Regarding the cornering of cardboard A: When the semi-finished product A1 after cornering forms A2, the semi-finished product A2 is a shell with a turned-up edge. The four corners of the shell are sealed due to the folded corners and play a lapping role with the adjacent edges, making the finished product more beautiful and firm. The entire production process of the product is automatically completed by various mechanisms of the equipment. The operator only needs to replenish the required feeding machine when receiving the replenishment call signal, or count and store the finished product K in the warehouse. Other products with square or rectangular dimensions can also be prepared. The equipment is fully automated, environmentally friendly, pollution-free, has no labor intensity, and has high safety. Embodiment

[0220] The same parts of this embodiment and Embodiment 1 will not be elaborated here. The differences are as follows:

[0221] As Figures 12-14 shown, the structures of the first feeding machine 1 and the third feeding machine 9 include a frame 1-1, a power mechanism arranged outside the frame 1-1, a transmission mechanism connected to the power mechanism, and a sliding component arranged on the frame.

[0222] The sliding component includes two longitudinal slide rails 1-2 arranged longitudinally left and right on the frame 1-1, two transverse slide rails 1-3 arranged perpendicular to the longitudinal slide rails 1-2. Two longitudinal sliders 1-18 are installed on each longitudinal slide rail 1-2, two transverse sliders 1-17 are installed on each transverse slide rail 1-3, four material clamping plates 1-19 respectively fixed on the four transverse sliders 1-17, and material clamps 1-20 respectively arranged on each material clamping plate 1-19.

[0223] Each transverse slide rail 1-3 is fixed on two longitudinal sliders 1-18 at the same end of the two longitudinal slide rails 1-2. The four material clamps 1-20 are placed facing each other at right angles, forming a right-angled quadrilateral frame in the middle of the four material clamps 1-20 for fixing materials.

[0224] A transverse limit clamp 1-15 is arranged on the outside of each transverse slider 1-17, and a longitudinal limit clamp 1-16 is arranged on the outside of each longitudinal slider 1-18. The transverse limit clamp 1-15 and the longitudinal limit clamp 1-16 are used to fix the positions of the material clamps 1-20.

[0225] The power mechanism is a feeding motor 1-4. The transmission mechanism includes two feeding speed reducers 1-7 fixed at the left and right ends of the frame 1-1, a longitudinal lead screw 1-9 connected to the output end of the feeding speed reducer 1-7, and a nut 1-10 arranged on the longitudinal lead screw 1-9.

[0226] The axis of the longitudinal lead screw 1-9 is arranged on the longitudinal center line 1-21 of the frame 1-1 and is perpendicular to the longitudinal center line 1-21. A pedestal bearing 1-13 is also arranged between the upper end of the longitudinal lead screw 1-9 and the frame 1-1 for fixing the longitudinal lead screw 1-9 on the frame 1-1.

[0227] A main pulley 1-5 is provided on the stock preparation motor 1-4, a secondary pulley 1-8 is provided on the stock preparation speed reducer 1-7, and a transmission belt 1-6 is connected between the main pulley 1-5 and the secondary pulley 1-8.

[0228] A transmission shaft 1-22 is further provided between the two stock preparation speed reducers 1-7 to synchronously rotate the two longitudinal lead screws 1-9.

[0229] A support plate 1-11 is provided between the two nuts 1-10. The two ends of the support plate 1-11 are respectively fixed to the upper end surfaces of the two nuts 1-10. A positioning plate 1-23 for placing materials is fixed on the upper end surface of the support plate 1-11. The center of the positioning plate 1-23 coincides with the center of the support plate 1-11. A positioning pin 1-25 is provided between the positioning plate 1-23 and the support plate 1-11, and a screw 1-24 is provided in the positioning pin 1-25.

[0230] Four material clamps 1-20 are arranged with two in front and two behind the longitudinal center line 1-21. There are two material clamps 1-20 on the front and rear surfaces of the support plate 1-11.

[0231] After rotating any end nut 1-10 to make the support plate 1-11 horizontal, it is fixed to the nuts 1-10 at both ends by screws. In this way, when the stock preparation motor 1-4 drives, the materials on the support plate 1-11 can be kept horizontal and lifted and lowered strictly along the controlled vertical line.

[0232] The positioning plate 1-23 and the support plate 1-11 are positioned by the positioning pin 1-25. Once the center position of the first positioning plate 1-23 is aligned, the position of the support plate 1-11 is determined. Therefore, when replacing the positioning plate 1-23, it is both convenient and accurate.

[0233] The center of the positioning plate 1-23 should coincide with the center of the feeding position. The positioning plate 1-23 has different size specifications to adapt to different feeding sizes.

[0234] By moving the longitudinal slider 1-18 and the transverse slider 1-17, the right-angled quadrilateral can be made larger or smaller, or can be a square or a rectangle, which is determined according to requirements.

[0235] When the square material is placed in the formed quadrilateral frame, tighten the transverse slider 1-17 and the longitudinal slider 1-18 so that its inner right-angled sides are close to the material. At this time, lock the transverse limit clamp 1-15 and the longitudinal limit clamp 1-16 to prevent outward movement to ensure accurate positioning.

[0236] The usage methods of the first stock preparation machine 1 and the third stock preparation machine 9 are as follows:

[0237] Position the first stock preparation machine 1 and the third stock preparation machine 9. Taking the center of their respective positioning plates 1-23 as the reference, align the centers of the positioning plates 1-23 with the feeding center. After alignment, fix the equipment.

[0238] Select the positioning plates 1-23 according to the size and direction of the stock preparation dimensions, fix them on the pallet 1-11, move the longitudinal slide block 1-18 and the transverse slide block 1-17 so that the inner right angles of the four material clamps 1-20 are respectively against the four right angles of the positioning plates 1-23. The square center formed by the four material clamps 1-20 is the feeding center. Lock the transverse limit clamp 1-15 and the longitudinal limit clamp 1-16 respectively to fasten the four material clamps 1-20.

[0239] Start the stock preparation motor 1-4 to lower the pallet 1-11 to the low position, place a certain amount of raw materials on the positioning plate 1-23 at the center of the four material clamps 1-20 and wait for feeding. When a certain amount of raw materials are used up, the stock preparation motor 1-4 receives a signal and starts to raise the pallet 1-11 by a certain distance to meet the feeding height. When the feeding is approaching the lower limit, the feeding system sends a feeding signal. When it is checked that the feeder is in place, the pallet 1-11 returns to the low position for easy feeding. In this way, a process of using materials and feeding is completed, and then this process is repeated. Embodiment

[0240] The same parts of this embodiment and Embodiment 2 will not be described in detail. The differences are as follows:

[0241] As Figures 15-17 shown, the second stock preparation machine 5 is the same as the first stock preparation machine 1 and the third stock preparation machine 9. The difference is that the frame 1-1 of the second stock preparation machine 5 includes a static frame 5-10 and a moving frame 5-1. The static frame 5-10 and the moving frame 5-1 are of the same width. The length of the static frame 5-10 is longer than that of the moving frame 5-1. On both sides of the upper plane of the static frame 5-10, two stock preparation slide rails 5-5 are longitudinally provided. There are two stock preparation slide blocks 5-8 on each stock preparation slide rail 5-5. The bottom surface of the moving frame 5-1 is fixed on the four stock preparation slide blocks 5-8.

[0242] The sliding assembly of the second stock preparation machine 5 has two groups, both of which are fixed on the moving frame 5-1.

[0243] One end of the static frame 5-10 is provided with a stock preparation drive machine 5-6. The output end of the stock preparation drive machine 5-6 is provided with a transverse lead screw 5-7. The two ends of the transverse lead screw 5-7 are respectively fixed on the static frame 5-10. A nut block 5-4 is provided on the transverse lead screw 5-7. The nut block 5-4 is fixedly connected to the left end face of the moving frame 5-1 through an angle plate 5-3.

[0244] There are a left fixing plate 5-9 and a right fixing plate 5-12 at both ends of the transverse lead screw 2-7.

[0245] When starting the stock preparation drive motor 5-6 to rotate the horizontal lead screw 5-7, the nut block 5-4 drives the moving frame 5-1 to move left and right along the stock preparation slide rail 5-5 on the static frame 5-10, so that the centers of the positioning plates 1-23 on the two pallets 1-11 can be aligned with the same feeding center position.

[0246] The usage method of the second stock preparation machine 5 is as follows:

[0247] There are two positioning plates 1-23 on the second stock preparation machine 5. When the material on one positioning plate 1-23 is used up to a certain extent, the stock preparation drive motor 5-6 drives the horizontal lead screw 5-7 to horizontally move the frame 5-1, so that the center of the other material-containing positioning plate 1-23 moves to the feeding position, and at the same time, the operator can replenish the empty material position.

[0254] The main cylinder 4-3 of the feeding machine 4 provided at Station 4 includes a rotary cylinder 4-3-1 and a linear cylinder 4-3-2. The rotary cylinder 4-3-1 is fixedly connected to the connecting plate 4-1, and the rotary cylinder 4-3-2 and the linear cylinder 4-3-2 are connected as a whole.

[0255] The loading machine 4 provided on the third station includes a second connecting plate 4-17, a second main cylinder 4-18 fixed to the second connecting plate 4-17, a fixing plate 4-24 fixedly connected to the output end of the second main cylinder 4-18, two frame assemblies provided on the fixing plate 4-24, two second sub-cylinders 4-19 respectively fixed to the two frame assemblies, a push plate 4-25 provided at the lower end of the fixing plate 4-24 and fixedly connected to the output end of the second sub-cylinder 4-19. A plurality of staples 4-26 penetrating the push plate 4-25 are further fixed to the lower end surface of the fixing plate 4-24. A push plate hole 4-29 for the staples 4-26 to pass through is provided on the push plate 4-25.

[0256] The output end of the second main cylinder 4-18 is provided with a second main cylinder top plate 4-23, and the second main cylinder top plate 4-23 is fixedly connected to the center of the fixing plate 4-24.

[0257] The frame assembly includes a frame top plate 4-20 and frame feet 4-27 provided at the lower end of the frame top plate 4-20. The frame feet 4-27 are fixedly connected to the upper end surface of the fixing plate 4-24.

[0258] The second sub-cylinder 4-19 is fixed to the upper end surface of the frame top plate 4-20. A cylinder guide rod 4-21 is provided on the output end of the second sub-cylinder 4-19. The cylinder guide rod 4-21 sequentially penetrates the frame top plate 4-20 and the fixing plate 4-24 and is fixedly connected to the push plate 4-25.

[0259] A sleeve 4-22 and a sleeve body 4-28 for fixing the cylinder guide rod 4-21 are provided inside the frame assembly. The cylinder guide rod 4-21 is sleeved inside the sleeve 4-22, and the sleeve 4-22 is sleeved inside the sleeve body 4-28.

[0260] The sleeve body 4-28 is fixedly connected to the fixing plate 4-24, and the sleeve body 4-28 and the sleeve 4-22 are fixedly connected.

[0261] Four staples 4-26 are respectively fixed at the four corners of the fixing plate 4-24, pass through the push plate hole 4-29 and their tips face downward.

[0262] Method of using the loading machine 4 on the first station 100: Place cardboard A on the loading machine

[0263] The main cylinder 4-3 works to make the main cylinder top plate 4-14 move downward, push the baffle 4-15 and drive the four suction cups 4-7 to move downward. The four suction cups 4-7 press against the cardboard A, and the suction nozzle 4-4 generates negative pressure to make the suction cups 4-7 suck the cardboard A. The main cylinder 4-3 works to return to its position, driving the cardboard A to move upward to the initial position of the main cylinder top plate 4-14.

[0264] The secondary cylinder 4-8 operates, causing the secondary cylinder top plate 4-10 to drive the material suction body 4-6 and the suction cups 4-7 to move upward. At this time, the negative pressure of the suction nozzle 4-4 is closed. When the suction cups 4-7 move upward past the baffle hole 4-16, the cardboard A is blocked and leaves the suction cups 4-7 to fall freely. When the baffle 4-15 presses the cardboard A onto a plane, the cardboard A will be placed on this plane.

[0265] Method of using the feeding machine 4 at station four 400: Place cardboard C on the feeding machine

[0266] The linear cylinder 4-3-2 operates to cause the main cylinder top plate 4-14 to move downward, pushing the baffle 4-15 and driving the four suction cups 4-7 to move downward. The four suction cups 4-7 press against the cardboard C, and the suction nozzle 4-4 generates negative pressure so that the suction cups 4-7 hold the cardboard C. The linear cylinder 4-3-2 operates to return to its original position, driving the cardboard C to rise to a high position. At this time, the rotary cylinder 4-3-1 can rotate 90° clockwise or counterclockwise. After completing the rotation action, the cylinder top plate 4-14 moves downward, bringing the cardboard C close to the placement plane, closing the suction nozzle 4-4, and the cardboard C will fall to the designated position.

[0267] Method of using the feeding machine 4 at station three 300: Place the foam board B on the feeding machine

[0268] Initial position: All cylinders are in the retracted position.

[0269] The second main cylinder 4-18 operates to cause the second main cylinder top plate 4-23 to move downward, driving all the components on the fixed plate 4-24 to move downward together. When the four staples 4-26 are inserted into the taken foam board B, the second main cylinder top plate 4-23 returns, causing the foam board B to rise to a high position. At this time, the two secondary cylinders 4-19 operate, causing the cylinder guide rods 4-21 to extend, so that the push plate 4-25 moves downward, pushing the foam board B off the four staples 4-26 and falling to the designated position. When the foam board B that is being held by the staples touches a plane and is pushed out, as the second main cylinder top plate 4-23 returns, the foam board B will remain on this plane. Embodiment

[0270] The similarities between this embodiment and Embodiment 1 will not be elaborated here. The differences are as follows:

[0271] As Figures 26-31As shown in Fig. 38, the corner lifting machine 2 includes a corner lifting machine frame 2-1, two corner lifting longitudinal beams 2-1-2 arranged in the width direction at the top of the corner lifting machine frame 2-1. A corner lifting cross brace 2-1-1 is fixed between the two corner lifting longitudinal beams 2-1-2. A vertical shaft 2-11-1 perpendicular to the upper end face of the corner lifting machine frame 2-1 is provided on the corner lifting cross brace 2-1-1. A corner lifting support plate 2-11 is provided at the upper end of the vertical shaft 2-11-1. A fixed scale plate 2-10 is fixed on the upper end face of the corner lifting support plate 2-11. Corner lifting longitudinal slide rails 2-2 are respectively fixed on the two corner lifting longitudinal beams 2-1-2. Two corner lifting longitudinal sliders 2-2-2 are provided on each corner lifting longitudinal slide rail 2-2. The two corner lifting longitudinal sliders 2-2-2 are symmetrically distributed on both sides of the corner lifting cross brace 2-1-1. A corner lifting cross slide rail 2-3 is fixed on each of the two corner lifting longitudinal sliders 2-2-2 on each side of the corner lifting cross brace 2-1-1. Two corner lifting cross sliders 2-3-2 are provided on each corner lifting cross slide rail 2-3. A folding angle mechanism is fixed on each corner lifting cross slider 2-3-2. The four folding angle mechanisms are respectively connected to the four corners of the fixed scale plate 2-10.

[0272] The folding angle mechanism includes a corner lifting fixed plate 2-4 arranged on the corner lifting cross slider 2-3-2 along the direction of the corner lifting cross slide rail 2-3. A fixed angle plate 2-4-3 is vertically fixed to the corner lifting fixed plate 2-4. A vertical plate 2-4-1 is perpendicularly welded to the corner lifting fixed plate 2-4. A corner lifting cylinder 2-5 is provided on the fixed angle plate 2-4-3. A roller pressing assembly is provided at the output end of the corner lifting cylinder 2-5. A jacking assembly connected to the roller pressing assembly is provided on the corner lifting fixed plate 2-4 between the fixed angle plate 2-4-3 and the vertical plate 2-4-1. The four jacking assemblies are respectively connected to the four corners of the fixed scale plate 2-10.

[0273] The output end of the corner lifting cylinder 2-5 is provided with a corner lifting working shaft 2-5-2. The corner lifting working shaft 2-5-2 penetrates through the fixed angle plate 2-4-3 and extends into one side of the corner lifting fixed plate 2-4.

[0274] The roller pressing assembly includes a guide shaft 2-6 connected to the corner lifting working shaft 2-5-2. A notch 2-6-2 is provided at the end of the guide shaft 2-6. Two pressing wheels 2-6-3 are provided in the notch 2-6-2. The pressing wheels 2-6-3 are fixed in the notch 2-6-2 through a first fixed shaft 2-6-4, so that the pressing wheels 2-6-3 can rotate in the notch 2-6-2. A chute 2-6-1 is also provided on the guide shaft 2-6.

[0275] A positioning seat 2-4-2 is horizontally fixed at the upper end of the vertical plate 2-4-1 on the side towards the center of the corner lifting cross slide rail 2-3. A lower platform 2-4-4 is provided on the upper end face of the positioning seat 2-4-2. The four lower platforms 2-4-2-1 are respectively used to place the four corners of the fixed scale plate 2-10.

[0276] The lifting assembly includes a bearing block 2-8-4 fixed to the angle-lifting fixing plate 2-4, a crank 2-8 disposed within the bearing block 2-8-4, and a guide rod 2-7-2 passing through the positioning seat 2-4-2 and abutting against the crank 2-8.

[0277] The opening of the bearing block 2-8-4 faces upward. A bearing 2-8-3 is provided between the crank 2-8 and the bearing block 2-8-4, and the bearing 2-8-3 and the bearing block 2-8-4 are integrally connected by a second fixed shaft 2-8-5.

[0278] The crank 2-8 includes a main arm 2-8-2 and a sub-arm 2-8-1. The main arm 2-8-2 is inserted into the sliding groove 2-6-1, and the sub-arm 2-8-1 abuts against the bottom end of the guide rod 2-7-2.

[0279] A guide sleeve 2-7-1 fixed to the positioning seat 2-4-2 is provided between the positioning seat 2-4-2 and the guide rod 2-7-2. The guide sleeve 2-7-1 extends out of the lower end face of the positioning seat 2-4-2. A spring 2-7 is also sleeved outside the guide sleeve 2-7-1. One end of the spring 2-7 is clamped to the guide rod seat 2-12 on the guide rod 2-7-2 and cannot escape from the guide rod 2-7-2.

[0280] An angle-lifting longitudinal limit clip 2-21 is provided on the angle-lifting longitudinal slider 2-2-2, and an angle-lifting transverse limit clip 2-20 is provided on the angle-lifting transverse slider 2-3-2.

[0281] The fixed-angle plate 2-4-3 and the angle-lifting fixing plate 2-4 form an acute angle, causing the fixed-angle plate 2-4-3 to incline inward at a certain angle.

[0282] The bearing block 2-8-4 is along the direction of the angle-lifting fixing plate 2-4 and abuts against the vertical plate 2-4-1 at the notch 2-6-2.

[0283] The bearing block 2-8-4 is firmly welded to the angle-lifting fixing plate 2-4 through the fixing hole 2-8-6.

[0284] An angle-lifting fixing plate 2-4 is fixed to each of the four angle-lifting transverse sliders 2-3-2. In this way, a plane is formed at the four corners between the four lower platforms 2-4-4, and the sizing plate 2-10 is placed on this plane, that is, the four corners of the sizing plate 2-10 are respectively placed on the four lower platforms 2-4-4.

[0285] The crank 2-8 can rotate a certain angle around the second fixed shaft 2-8-5 as the axis.

[0286] The usage method of the angle-lifting machine 2 is as follows:

[0287] Correct the position of the angle fixing plate 2-4, place the semi-finished cardboard on the fixed-size plate 2-10, make the four guide rods 2-7-2 face the center of the four folding corners 50-1 respectively, lock the angle longitudinal limit clamp 2-21 after alignment, fix the angle longitudinal slider 2-2-2, ensure the longitudinal size of the guide rod 2-7-2 is aligned, lock the angle transverse limit clamp 2-20, fix the angle transverse slider 2-3-2, ensure the transverse size of the guide rod 2-7-2 is aligned, and the angle cylinder 2-5 starts the angle. The working shaft 2-5-2 retracts, driving the slide 2-6-1 and pushing the main arm 2-8-2 outward, causing the crank 2-8 to rotate, causing the auxiliary arm 2-8-1 to rotate upward, pushing the guide rod 2-7-2 upward, and the spring 2-7 is compressed. When the angle working shaft 2-5-2 is fully retracted, the guide rod 2-7-2 is in a high position, the slide 2-6-1 prevents the main arm 2-8-2 from rotating, and the spring 2-7 is compressed to the shortest length. The semi-finished cardboard is removed and the equipment is in the initial state.

[0288] When the semi-finished cardboard is placed tightly on the fixed-length board 2-10, the folding angle 50-1 is blocked when it contacts the top of the guide rod 2-7-2 and is folded up to 90° along the crease 50-2. At this time, a signal is given, and the folding working shaft 2-5-2 of the folding cylinder 2-5 extends to make the slide 2-6-1 move forward, pushing the pressing wheel 2-6-3 forward, and the main arm 2-8-2 loses its blocking force in front. The spring 2-7 pushes the guide rod seat 2-12 downward, and the guide rod seat 2-12 pushes the auxiliary arm 2-8-1 to rotate downward. Since there is no resistance in front of the main arm 2-8-2, it continues to move forward. When the guide rod 2-7-2 descends to a certain height, the pressing wheel 2-6-3 presses against the folding angle 50-1 and continues to work. At this time, the pressing wheel 2-6-3 is in a semi-pressed state with respect to the folding angle 50-1. , when the guide rod 2-7-2 descends to the lowest position and is flush with the positioning seat 2-4-2, the folding angle 50-1 of the pressing wheel 2-6-3 is in a completely compacted state, a signal is given, the starting angle working shaft 2-5-2 retracts, driving the slide 2-6-1 and pushing the main arm 2-8-2 outward, causing the crank 2-8 to rotate in the opposite direction, causing the auxiliary arm 2-8-1 to rotate upward, pushing the guide rod 2-7-2 upward, and the spring 2-7 is compressed. When the starting angle working shaft 2-5-2 is fully retracted, the guide rod 2-7-2 is in a high position, and the slide 2-6-1 prevents the main arm 2-8-2 from rotating. At this time, the spring 2-7 is compressed to the shortest length, and the finished cardboard A is taken away and placed in the designated position to prepare for the next process. The equipment is in the initial state of the next working process.

[0289] Because the fixed angle plate 2-4-3 is at a certain inclination angle, when the pressing wheel 2-6-3 moves forward and completely contacts the folding angle 50-1, it is a squeezing process. When the pressing wheel 2-6-3 retracts, the folding angle 50-1 is in a vertical state, so that the automatically completed cardboard A product meets the requirements. Example

[0291] As Figures 32-36 shown, the glue applicator 7 includes a glue application machine frame 7-1, two glue application longitudinal slide rails 7-6 respectively arranged on both sides of the upper end surface of the glue application machine frame 7-1. Each glue application longitudinal slide rail 7-6 is provided with a glue application longitudinal slider 7-6-2. A glue application transverse slide rail 7-8 is fixed between the two glue application longitudinal sliders 7-6-2. Two glue application transverse sliders 7-8-4 are arranged on the glue application transverse slide rail 7-8.

One end of the two spline sleeves 7-22 in the two glue boxes 7-20 that face each other extends to the outside of the glue box 7-20. The two spline sleeves 7-22 are connected into one body through a spline shaft 7-23 sleeved in the spline sleeve 7-22.

[0298] The glue box 7-20 is filled with glue liquid 7-20-2, and the glue wheel 7-25 is immersed in the glue liquid 7-20-2.

[0299] A sub-sprocket 7-24 is arranged on the spline shaft 7-23, and the sub-sprocket 7-24 is connected with a large driving sprocket 7-5-5 through a second chain 7-10 in a transmission manner.

[0300] The spline sleeve 7-22 is fixed on two opposite inner side walls of the glue box 7-20 through two groups of fixing components. The fixing components include a fixing chamber 7-21 arranged on the inner side wall of the glue box 7-20, a snap ring 7-21-1, a glue applying bearing 7-21-2, a spacer ring 7-21-3, and a skeleton oil seal 7-21-4 arranged in the fixing chamber 7-21.

A glue limiting plate 7-26-2 is further arranged on the rectangular hole of the glue rack 7-26. The glue limiting plate 7-26-2 is used for scraping off excessive glue liquid on the glue wheel 7-25.

[0302] A glue box seat 7-20-1 is fixed at the bottom of the glue box 7-20. A glue box fixing plate 7-8-5 is further arranged between the glue applying cross slider 7-8-4 and the glue box seat 7-20-1.

[0303] A glue wheel groove 7-25-1 is arranged on the glue wheel 7-25.

[0304] The raw material positioning mechanism includes positioning frames 7-40 arranged on both sides of the glue applying machine frame 7-1, a positioning sub-plate 7-40-3 arranged between the two positioning frames 7-40, and a positioning main plate 7-40-4 arranged on the upper end surface of the positioning sub-plate 7-40-3. The positioning main plate 7-40-4 is arranged in the middle of the two glue wheels 7-25.

[0305] Two bead switches 7-30 for controlling the commutation of the glue applying reduction motor 7-3 are arranged on the longitudinal beam 7-1-2 on any one side. One end of the glue applying cross slide rail 7-8 close to the bead switch 7-30 extends outward to a length exceeding the bead switch 7-30.

[0306] A glue applying cross limit clamp 7-8-3 is further arranged on the glue applying cross slider 7-8-4.

[0307] The glue - applying longitudinal slider 7 - 6 - 2 bears all the weights of the glue - applying fixed plate 7 - 2, the glue - applying reducer motor 7 - 3, the T - type reducer 7 - 5, the transition plate 7 - 7, the glue - applying transverse slide rail 7 - 8, the glue box 7 - 20 and its accessories. The rack 7 - 4 is parallel to the two glue - applying longitudinal slide rails 7 - 6. When the main gear 7 - 5 - 1 rotates along the rack 7 - 4, the above - mentioned components drive the glue - applying longitudinal slider 7 - 6 - 2 to move along the glue - applying longitudinal slide rail 7 - 6.

[0308] The transmission between the main sprocket 7 - 3 - 2 of the glue - applying reducer motor 7 - 3 and the small transmission sprocket 7 - 5 - 4 of the T - type reducer 7 - 5 is realized through the first chain 7 - 9.

[0309] The transmission between the large transmission sprocket 7 - 5 - 5 of the T - type reducer 7 - 5 and the secondary sprocket 7 - 24 on the spline shaft 7 - 23 is realized through the second chain 7 - 10.

[0310] After adjusting the inner spacing of the two glue boxes 7 - 20 to be equal to the width of the positioning secondary plate 7 - 40 - 3, the spline sleeve 7 - 22 and the spline shaft 7 - 23 are fixed by bolts.

[0311] The usage method of the glue - applying machine 7 is as follows:

[0312] Pour the glue liquid 7 - 20 - 2 into the glue box 7 - 20. Adjust the two glue wheels 7 - 25 to be equidistant from the side of the positioning secondary plate 7 - 40 - 3 according to the size of the cardboard. Loosen the glue - applying transverse limit clamp 7 - 8 - 3 and loosen the screw to move the glue box 7 - 20. After the distance between the two glue wheels 7 - 25 along the outside is equal to the width of the cardboard, tighten the glue - applying transverse limit clamp 7 - 8 - 3 and tighten the screw to restrict the transverse movement of the glue wheels 7 - 25. Adjust the appropriate height of the positioning secondary plate 7 - 40 - 3. When the cardboard is placed on the positioning main plate 7 - 40 - 4, the glue wheels 7 - 25 can smoothly apply glue to it.

[0313] Start the glue - applying reduction gear motor 7 - 3, which makes the main sprocket 7 - 3 - 2 rotate. The main sprocket 7 - 3 - 2 drives the first chain 7 - 9, and then drives the small transmission sprocket 7 - 5 - 4 to rotate. Since the small transmission sprocket 7 - 5 - 4 and the large transmission sprocket 7 - 5 - 5 are integrally coaxial, the large transmission sprocket 7 - 5 - 5 drives the auxiliary sprocket 7 - 24 to rotate through the second chain 7 - 10. The auxiliary sprocket 7 - 24 drives the spline sleeve 7 - 22, and the spline sleeve 7 - 22 drives the rubber wheel 7 - 25 to rotate. Since the rubber wheel 7 - 25 is immersed in the glue liquid 7 - 20 - 2, and there are glue grooves 7 - 25 - 1 on the rubber wheel 7 - 25, when the rubber wheel 7 - 25 rotates, the glue liquid 7 - 20 - 2 with a certain viscosity stored in the glue grooves 7 - 25 - 1 is lifted and rotates with the rubber wheel 7 - 25. There is a limited distance between the glue - limiting plate 7 - 26 - 2 and the rubber wheel 7 - 25, and the excess glue liquid 7 - 20 - 2 is scraped off by the glue - limiting plate 7 - 26 - 2 and falls into the glue box 7 - 20, making the glue - applying amount of the rubber wheel 7 - 25 appropriate.

[0314] At this time, the small transmission sprocket 7 - 5 - 4 drives the main shaft 7 - 5 - 6 in the horizontal direction of the T - type reduction gear 7 - 5 to rotate. The main shaft 7 - 5 - 6 drives the auxiliary shaft 7 - 5 - 2 to rotate, and the main gear 7 - 5 - 1 installed on the auxiliary shaft 7 - 5 - 2 rotates. The main gear 7 - 5 - 1 meshes with the rack 7 - 4. Therefore, the main gear 7 - 5 - 1 rotates on the rack 7 - 4, and then drives the T - type reduction gear 7 - 5 and the glue - applying fixing plate 7 - 2 to move, realizing that all the components directly or indirectly pressed on the glue - applying longitudinal slide rail 7 - 6 - 2 move along the glue - applying longitudinal slide rail 7 - 6 - 2, and realizing that the rubber wheel 7 - 25 rotates while moving horizontally. The power for the movement comes from the transmission of the glue - applying reduction gear motor 7 - 3 to the main gear 5 - 1.

[0315] When moving to the glue - applying cross slide rail 7 - 8 touches the bead switch 7 - 30, the glue - applying reduction gear motor 7 - 3 gets a signal and reverses, and the rubber wheel 7 - 25 also reverses and moves horizontally in the opposite direction.

[0316] Glue - applying to the cardboard: In the initial position, the glue - applying cross slide rail 7 - 8 stops at one end close to any bead switch 7 - 30. The cardboard is pressed on the upper plane of the positioning main board 7 - 40 - 4. A signal is given, and the rubber wheel 7 - 25 rotates and moves forward smoothly horizontally. When the top of the rubber wheel 7 - 25 touches the bottom edge of the cardboard, glue - applying is carried out on it. When passing through the bottom of the cardboard, the two bottom edges are finished with glue - applying. After the cardboard rotates 90°, it is placed back on the positioning main board 7 - 40 - 4. When the glue - applying cross slide rail 7 - 8 under the rubber wheel 7 - 25 touches the opposite bead switch 7 - 30 when the rubber wheel 7 - 25 moves forward, at this time, the rubber wheel 7 - 25 reverses and moves back, and then glues the cardboard again. After passing through the cardboard, the cardboard is placed at the designated position. Instantly, another cardboard is taken and placed on the positioning main board 7 - 40 - 4. At this time, after the glue - applying cross slide rail 7 - 8 under the rubber wheel 7 - 25 touches the bead switch 7 - 30 at this end, it rotates forward again, repeating the next working process.

[0317] The rotation direction of the rubber wheel 7-25 is the same as the direction of applying glue to the cardboard by rolling. Just like an automobile wheel rotates on the ground, except that the automobile wheel is above the ground while the rubber wheel 7-25 is below the cardboard. The movement of an automobile is driven by the wheels, while the movement of the rubber wheel 7-25 is driven by the rotation of the main gear 7-5-1 on the rack 7-4 to drive the rubber wheel 7-25 to move horizontally. The rotation and movement of the rubber wheel 7-25 are synchronous.

[0318] The rubber wheel 7-25 applies glue to the four sides of the cardboard through a back-and-forth movement. The width of the glue application is the width of the rubber wheel 7-25. The forward and reverse rotations of the rubber wheel 7-25 come from the forward and reverse rotations of the glue application reduction motor 7-3. The forward and reverse rotations of the glue application reduction motor 7-3 also drive the main gear 7-5-1 to rotate forward and backward, causing the rubber wheel 7-25 to move back and forth. The commands for the forward and reverse rotations of the glue application reduction motor 7-3 come from the signals given by two magnetic bead switches 7-30. Embodiment

[0319] The similarities between this embodiment and Embodiment 1 will not be elaborated here. The differences are as follows:

[0320] As Figure 37 shown, replace the transmission structure of the six-cam dividing machine 3-5 and the reduction motor 3-8 in Embodiment 1 with:

[0321] External teeth are provided on the outer ring 3-72 of the slewing bearing. A fixed vertical foot 9-1 is fixed on the side of the table 3-71. A fixed horizontal foot 9-5 is provided on the fixed vertical foot 9-1. A servo motor 9-3 is fixed on the fixed horizontal foot 9-5. A servo motor shaft 9-6 is provided at the output end of the servo motor 9-3. A main gear 9-7 is fixed on the servo motor shaft 9-6 through a pressure plate 9-8. The main gear 9-7 meshes with the external teeth of the outer ring 3-72 of the slewing bearing.

[0322] The servo motor 9-3 receives signals and drives the main gear 9-7 to rotate a certain number of turns according to the commands. The main gear 9-7 drives the outer ring 3-72 of the slewing bearing and the slewing platform 3-73 to rotate an angle of 60° through the external teeth of the outer ring 3-72 of the slewing bearing. The intermittent rotation of the slewing platform 3-73 is realized through this transmission method. The setting of this driving method can facilitate the maintenance of the main power servo motor 9-3.
