Description

Technical Field

[0001] This invention relates to the field of toilet manufacturing equipment, specifically to a toilet production line and its operating method. Background Technology

[0002] Toilet production requires the toilet blank to be formed in an injection molding machine. A casting liquid is injected into the molding mold, and after the liquid solidifies to a certain extent, the mold is opened and the toilet blank is removed. Existing molding equipment, as shown in Chinese patents CN109940735A or CN109940736A, has an upper end seat, a lower end seat, and guide pillars fixedly connected between the upper and lower end seats. The upper mold, middle mold, and sliding sleeve are mounted on the guide pillars, thus achieving mold closing and opening. The use of guide pillars not only increases manufacturing costs, but also means that the overall height of the molding mold after closing remains the distance between the upper and lower end seats, still occupying a significant amount of space.

[0003] After the toilet blank is formed by injection molding in a mold of a grouting machine, it needs to be transferred out of the mold after the mold is opened to be transported to the next process. A moving trolley carrying a pallet moves back and forth in and out of the mold to transfer the toilet blank. The moving trolley travels on a track, which blocks the sides of its path. Since the toilet blank takes a long time to form from the start of injection molding, workers or materials need to detour from one side of the track to the other, thus affecting production efficiency.

[0004] After the toilet blanks are removed from the injection molding machine, the pallets and toilet blanks on the trolley need to be moved promptly so that the trolley can carry the empty pallets to receive the toilet blanks produced during the next mold opening. Toilet blanks are quite heavy, and some injection molding machines produce two or more toilet blanks at a time, resulting in pallets carrying two or more blanks. Manual handling is inefficient, labor-intensive, and prevents automated production.

[0005] In view of this, the applicant conducted in-depth research on the aforementioned deficiencies in the prior art, which led to this case. Summary of the Invention

[0021] A method for operating a toilet production line, using the aforementioned toilet production line, further includes the following steps:

[0022] ① The middle mold descends under the drive of the second lifting cylinder, so that the middle mold contacts the bottom mold, the side mold closes and is fixed, and the upper mold descends, closes and is pressurized;

[0023] ② Tilt the mold cavity, with an inclination range of 0-30 degrees, and inject grout from the lowest point, waiting for the toilet blank to form; while waiting for the toilet blank to form, the track in the middle of the trolley track is folded to form a transverse channel, at which time the moving trolley is located on the trolley track on the side closer to the conveyor belt.

[0024] ③ The upper mold rises first to create a small gap between the upper mold and the middle mold. The side mold disengages and moves back. The middle mold, upper mold, and toilet blank rise together. The moving trolley enters, the vacuum in the middle mold is closed, and air is pumped to demold the toilet blank. After that, the middle mold and upper mold continue to rise. The lower end of the middle mold is higher than the toilet blank.

[0025] ④ The moving trolley carrying the toilet blank leaves the grouting machine;

[0026] ⑤ The lifting device of the mold transfer device transfers the toilet blank on the moving trolley together with the pallet into the conveyor belt;

[0027] ⑥ The pallets are transported along the conveyor belt.

[0028] With the above structure, the toilet production line and working method of the present invention have at least the following beneficial effects:

[0029] 1. A toilet blank is formed inside the grouting machine. After the mold is opened, the moving trolley enters the grouting machine to receive the toilet blank and returns to the demolding transfer device along the trolley track. Since grouting requires a certain waiting time, the trolley track can be folded during this time to form a transverse passage in the middle of the track, facilitating the movement of workers and materials from one side of the track to the other. Thus, when several grouting machines are arranged side-by-side, the supervisor can also easily and quickly move from one side of the trolley to the other through the transverse passage formed by the folded trolley track, without having to go around the grouting machine.

[0030] 2. When the lifting device transfers the tray carrying the toilet bowl blank, the lifting frame is raised and lowered via a lifting cylinder. After the lifting frame lowers to its position, the rotation drive mechanism drives the synchronous belt to rotate all the first synchronous pulleys 90 degrees, allowing the lifting hook to catch the tray. Then the lifting frame rises, causing the tray to leave the moving trolley, and then the lifting frame lowers, causing the tray to fall onto the conveyor belt.

[0031] Third, during mold closing, the upper end seat and the middle frame move towards the lower end seat. At this time, the first and second lifting cylinders act as driving forces, and the piston rod of the pressure cylinder serves as a guide post for the upper and lower end seats. During pressurization, hydraulic oil is injected into the pressure cylinder to press the upper and lower end seats together, thus pressing the upper, middle, and lower molds together. Using the piston rod of the pressure cylinder as a guide post reduces manufacturing costs. After mold closing, the distance between the upper and lower end seats is smaller, resulting in a more compact overall structure and more flexible equipment rotation.

[0032] Compared with existing technologies, this invention achieves the demolding and transfer of toilet blanks by arranging multiple sets of grouting machines side by side and equipping each with a demolding and transfer device. Furthermore, a foldable structure is provided in the middle of the trolley track, allowing a transverse channel to be formed in the middle of the trolley track when needed, thus improving the efficiency of the toilet blank production process.

Detailed Implementation

[0049] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0050] like Figures 1 to 11As shown, this invention relates to a toilet production line, comprising several injection molding machines 10 arranged in sequence. Each injection molding machine 10 is provided with a demolding transfer device 700 on the same side. The demolding transfer device 700 is provided with a conveyor belt 200, and two adjacent conveyor belts 200 are connected in sequence along the arrangement direction of the injection molding machines 10. The demolding transfer device 700 is provided with a trolley track 8 extending into the injection molding machine 10. The trolley track 8 is provided with a moving trolley 7 for transferring toilet blanks 300. The middle of each trolley track 8 can be folded to form a transverse channel 88 that crosses the trolley track 8. The transverse channel 88 formed by multiple trolley tracks 8 can form a continuous channel along the arrangement direction of the injection molding machines 10.

[0051] Thus, the present invention relates to a toilet production line and its operating method. A toilet blank 300 is formed inside a grouting machine 10. After mold opening, the moving trolley 7 enters the grouting machine 10 to receive the toilet blank 300 and returns to the demolding transfer device 700 along the trolley track 8. Since grouting requires a certain waiting time, the trolley track 8 can be folded to form a transverse channel 88 in the middle of the trolley track 8, facilitating the movement of workers and materials from one side of the trolley track 8 to the other. In this way, when several grouting machines 10 are arranged side-by-side, the caregiver can also conveniently and quickly move from one side of the trolley to the other through the transverse channel 88 formed by the folded trolley track 8, without having to go around the grouting machine 10.

[0052] Preferably, the demolding transfer device 700 is equipped with a lifting device 9, and the moving trolley 7 can move to a position below the lifting device 9; the lifting device 9 is fixedly mounted on the support frame 91, and the conveyor belt 200 is mounted on the support frame 91 and located directly below the lifting device 9; the lifting device 9 includes a lifting frame 94, a lifting cylinder, and several lifting rods 992, the upper and lower ends of the lifting cylinder are respectively connected to the support frame 91 and the lifting frame 94 to drive the lifting frame 94 to move vertically; the lifting frame 94 is located below the crossbeam 92, and a guide rod 95 is vertically mounted on the lifting frame 94, the guide rod 95 passes through the crossbeam 92 and is slidably connected to the crossbeam 92; a guide sleeve 93 is mounted on the crossbeam 92, and the guide rod 95 is connected to the guide sleeve. A sliding connection is used to reduce frictional resistance; the upper end of the lifting rod 992 is connected to the lifting frame 94, and a lifting hook 993 for hooking and releasing the tray 75 is provided below the lifting rod 992; the upper end of the lifting rod 992 is rotatably connected to the lifting frame 94, and a first synchronous pulley 972 is fixedly connected to each lifting rod 992 and coaxially arranged; a synchronous belt 971 is simultaneously wrapped around the first synchronous pulley 972 to drive the first synchronous pulley 972 to rotate synchronously at the same angle; the lifting rods 992 are distributed along the edge shape of the support rod, and a lifting hook 993 perpendicular to the lifting rod 992 is provided at the lower end of each lifting rod 992; a rotation drive mechanism 98 is provided on the lifting frame 94 to drive the synchronous belt 971 to drive the first synchronous pulley 972 to rotate within the range of 0-90 degrees.

[0053] When the lifting device 9 transfers the tray 75 carrying the toilet bowl blank 300, the lifting frame 94 is raised and lowered via a lifting cylinder. After the lifting frame 94 is lowered into position, the rotation drive mechanism 98 drives the synchronous belt 971 to rotate all the first synchronous pulleys 972 by 90 degrees, so that the lifting hook 993 can hook the tray 75. Then the lifting frame 94 rises, causing the tray 75 to leave the moving trolley 7, and then the lifting frame 94 lowers, causing the tray 75 to fall onto the conveyor belt 200.

[0054] Preferably, the mobile trolley 7 has a body 71, four wheels 72, a travel motor 73 and a lifting mechanism 74. The wheels 72 are located below the body 71 and are placed on the trolley track 8. The travel motor 73 can drive at least one of the wheels 72 to rotate.

[0055] The lifting mechanism 74 includes a lifting cylinder and a jacking head. The lifting cylinder is fixedly connected to the vehicle body 71. The piston rod of the lifting cylinder is arranged downward. The jacking head is provided on the piston rod of the lifting cylinder. The jacking head can abut against the upper surface of the trolley track 8 to lift the vehicle body 71.

[0056] The mobile trolley 7 has wheels 72 located below the trolley body 71 and a lifting mechanism 74. The wheels 72 are driven to rotate by the travel motor 73, thereby driving the mobile trolley 7 to travel along the trolley track 8. When the lifting cylinder lifts downward, the trolley body 71 is lifted upward, which not only restricts the movement of the trolley body 71, but also facilitates the support plate 75 on the mobile trolley 7 to receive the demolded toilet blank 300 in the grouting machine 10.

[0057] The trolley track 8 includes a left track and a right track for the moving trolley 7 to travel on. The left track includes a first track 81, a second track 82, and a third track 83.

When in the working position, the second track 82 and the fifth track 85 are connected to the first track 81 and the fourth track 84, respectively, to form a continuous left track and a right track.

[0058] Preferably, the track support 87 is further provided with a switching cylinder 891 for driving the second track 82 and the fifth track 85 to switch positions respectively. The cylinder seat of the switching cylinder 891 is rotatably connected to the track support 87, and the piston rod of the switching cylinder 891 is connected to the second track 82 or the fifth track 85. The first track 81 and the fourth track 84 have a first chamfer 892 at the end near the track support 87, and the second track 82 and the fourth track 84 have a second chamfer 893 at the end away from the rotation point. When in the working position, the first chamfer 892 and the second chamfer 893 are in contact with each other. The lower surface of the first track 81 and the fourth track 84 near the track support 87 is provided with a first support seat 894, and the movable end of the second track 82 and the fifth track 85 can be placed on the first support seat 894. The third track 83 and the sixth track 86 have a second support seat 895, and the second support seat 895 is disposed on the lower surface of the second track 82 and the fifth track 85. By setting the first support seat 894 and the second support seat 895 to provide auxiliary support for both ends of the second track 82 and the fifth track 85, the second track 82 and the fifth track 85 can more stably support the mobile trolley 7.

[0059] Preferably, the first track 81, the second track 82, the third track 83, the fourth track 84, the fifth track 85, and the sixth track 86 are all straight tracks. The first track 81 and the third track 83 are collinear, and the fourth track 84 and the sixth track 86 are collinear. The second track 82 and the fifth track 85 are of equal length. Each track includes a supporting crossbar 896 and a V-shaped guide rail 897, with the V-shaped guide rail 897 positioned at the upper end of the supporting crossbar 896. The lengths of the third track 83 and the sixth track 86 are greater than twice the length of the moving trolley 7 in the direction of travel. Using straight tracks facilitates production and processing. The supporting crossbar 896 supports the V-shaped guide rail 897, thus ensuring the strength of the track. The V-shaped guide rail 897 cooperates with the guide wheels of the moving trolley 7.

[0060] Preferably, the rotation drive mechanism 98 includes a second synchronous pulley 981, a rocker arm 983, and a swing drive cylinder 984.

The position of the adjusting seat 991 on the lifting frame 94 can be adjusted and fixed laterally. The swing drive cylinder 984 drives the rocker arm 983 on the second synchronous pulley 981 to rotate within a 90-degree range. Through the transmission of the synchronous belt 971, the first synchronous pulley 972 rotates 90 degrees. The timing belt 971 is a double-sided toothed timing belt 971. When the adjusting seat 991 is adjusted laterally, the tension of the timing belt 971 is adjusted.

[0061] The lifting cylinder includes a first lifting cylinder 961 and a second lifting cylinder 962; the cylinder body of the first lifting cylinder 961 is fixedly mounted on the crossbeam 92 on the support frame 91, the piston rod of the first lifting cylinder 961 is arranged downward and fixedly connected to the cylinder body of the second lifting cylinder 962, the piston rod of the second lifting cylinder 962 is arranged downward and fixedly connected to the lifting frame 94; the stroke of the first lifting cylinder 961 is greater than the stroke of the second lifting cylinder 962.

[0062] The lifting drive mechanism 96 includes a first lifting cylinder 961 and a second lifting cylinder 962. Initially, the second lifting cylinder 962 actuates first, causing the lifting hook 993 to descend below the lower surface of the pallet 75. After the lifting rod 992 rotates, the second lifting cylinder 962 rises, disengaging the pallet 75 from the moving trolley 7 for easy removal. Subsequently, the first lifting cylinder 961 and the second lifting cylinder 962 can be used together to descend to a designated position, such as on the conveyor belt 200, disengaging the pallet 75 from the lifting hook 993. By combining the two position states of the second lifting cylinder 962, the lifting hook 993 can have four position states in the height direction, thereby realizing the transfer of the pallet 75 from the moving trolley 7 and its placement on the conveyor belt 200.

[0063] Preferably, the grouting machine 10 includes an upper end seat 1, a lower end seat 3, a middle frame 2, an upper mold 11, a middle mold 21, a lower mold 31, and a side mold 6; the upper mold 11 is fixedly installed on the lower surface of the upper end seat 1, the lower mold 31 is fixedly installed on the upper surface of the lower end seat 3, and the middle mold 21 is fixedly installed on the middle frame 2; the side mold 6 is slidably disposed on the side of the lower end seat 3 and can be enclosed with the upper mold 11, the middle mold 21, and the lower mold 31 to form a mold cavity; the upper end of the upper end seat 1 is provided with two first lifting cylinders 12, two second lifting cylinders 13, and four pressurizing cylinders 14, the lower end of the piston rod of the first lifting cylinder 12 is fixedly connected to the lower end seat 3; the second lifting cylinders 12 are fixedly installed on the lower end seat 3 ..., the second lifting cylinders 12 are fixedly installed on the lower end seat 3, the lower end of the piston rod of the first lifting cylinder 12 is fixedly installed on the lower end seat 3, the lower end of the piston rod of the first lifting cylinder 12 is fixedly installed on the lower end seat 3, the lower end of the piston rod of the second lifting cylinder 12 is fixedly installed on the lower end seat 3, the lower end of the piston rod of the first lifting cylinder 12 is fixedly installed on the lower end seat 3, the lower end of the piston rod of the first lifting cylinder 12 is fixedly installed on the lower end seat 3, the lower end of the piston rod of the second lifting cylinder 12 The lower end of the lowering cylinder 13 is fixedly connected to the middle frame 2; the piston rod of the pressurizing cylinder 14 passes vertically downward through the upper end seat 1 and the middle frame 2 and is fixedly connected to the lower end seat 3; the middle frame 2 is slidably connected to the piston rod of the pressurizing cylinder 14; the first lifting cylinder 12, the second lifting cylinder 13 and the two pressurizing cylinders 14 located on the same side of the upper mold 11 are arranged in a straight line, and the first lifting cylinder 12 and the second lifting cylinder 13 are located between the two pressurizing cylinders 14; the piston rod of the first lifting cylinder 12 is slidably connected to the middle mold 21; a sliding bearing 22 is fixedly provided on the middle frame 2, and the piston rod of the pressurizing cylinder 14 is slidably connected to the sliding bearing 22.

[0064] During mold closing, the upper end seat 1 and the middle frame 2 move towards the lower end seat 3. At this time, the first lifting cylinder 12 and the second lifting cylinder 13 serve as the driving force, and the piston rod of the pressurizing cylinder 14 acts as a guide post for the upper end seat 1 and the lower end seat 3. During pressurization, hydraulic oil is injected into the pressurizing cylinder 14 to press the upper end seat 1 and the lower end seat 3 together, thus pressing the upper mold 11, the middle mold 21, and the lower mold 31 together. Using the piston rod of the pressurizing cylinder 14 as a guide post reduces manufacturing costs. After mold closing, the distance between the upper end seat 1 and the lower end seat 3 is smaller, resulting in a more compact overall structure and more flexible equipment rotation.

[0065] Preferably, the system further includes a base 4, on which two first columns 41 are symmetrically arranged at the upper end, and two second columns 32 are symmetrically arranged at both ends of the lower mold 31. The upper ends of the first columns 41 and the second columns 32 are rotatably connected around a horizontal axis. The height of the horizontal axis is higher than the height of the upper surface of the lower mold 31. The lower mold 31 is also provided with a third column 33 and a tilting cylinder 42. The two ends of the tilting cylinder 42 are rotatably connected to the upper end of the third column 33 and the base 4, respectively. The horizontal axis passes through the center of the middle mold 21 when the mold is closed.

[0066] The first column 41 includes two uprights 411 and a bearing 412 with a seat. The two uprights 411 are arranged parallel to each other. The lower ends of the two uprights 411 are fixedly connected to the base 4, and the upper ends of the two uprights 411 are fixedly connected to the bearing 412 with a seat. The inner ring of the bearing 412 is connected to a rotating shaft, which is fixedly connected to the second column 32. The second column 32 and the third column 33 are arranged parallel to each other. By setting the first column 41 and the second column 32, the horizontal axis of the mold assembly is raised when rotating, and the horizontal axis is closer to the center of the middle mold 21 and the overall center of gravity. This makes the swing range of the upper end seat 1 smaller when tilting, making the overall molding equipment more compact and reducing the space occupied. Moreover, since the horizontal axis is closer to the center of gravity of the mold, it is easier to drive the tilting cylinder 42 to flip, and a smaller cylinder can be used, reducing the cost of the equipment.

[0067] Preferably, the side mold 6 is symmetrically provided with fastening mechanisms 5 on both sides, including a guide rail seat 51, a sliding guide rail 511, a first hydraulic cylinder 513, a slider 512, a mounting base 52, a tailstock 53, a second hydraulic cylinder 531, a hook 54, and a fastening cylinder 55; the guide rail seat 51 is fixedly connected to the lower end seat 3; the sliding guide rail 511 is fixedly mounted on the guide rail seat 51, the mounting base 52 is fixedly connected to the slider 512, the slider 512 is slidably mounted on the sliding guide rail 511, and the first hydraulic cylinder 513 is connected to the ends of the mounting base 52 and the guide rail seat 51 respectively to drive the mounting base 52 and the slider 512 to move along the sliding guide rail 511; the fastening mechanism 55 is provided with fastening mechanisms 5 on both sides, including a guide rail seat 51, a sliding guide rail 511, a first hydraulic cylinder 513, a slider 512, a mounting base 52, a tailstock 53, a second hydraulic cylinder 531, a hook 54, and a fastening cylinder 55; the guide rail seat 51 is fixedly connected to the lower end seat 3; the sliding guide rail 511 is fixedly mounted on the guide rail seat 51, the first hydraulic cylinder 513 ... second hydraulic cylinder 531 is fixedly mounted on the guide rail seat 51, the Mounting base 52 is fixedly connected to side mold 6; the cylinder body of the second hydraulic cylinder 531 is fixedly connected to the mounting base 52, the piston rod of the second hydraulic cylinder 531 moves in a direction parallel to the length direction of the sliding guide rail 511, the piston rod of the second hydraulic cylinder 531 is fixedly connected to tail seat 53, one end of the hook 54 has a hook head 541, and the end of the hook 54 away from the hook head 541 is rotatably connected to the tail seat 53; the clamping cylinder 55 is fixedly mounted on the mounting base 52, and the piston rod of the clamping cylinder 55 is connected to the middle part of the hook 54; it also includes a locking block 56 fixedly mounted on the middle mold 21, and the hook head 541 of the hook 54 can be fastened to the locking block 56.

[0068] In use, the first hydraulic cylinder 513 drives the mounting base 52 and the slider 512 to move along the sliding guide rail 511, bringing the side mold 6 closer to the middle mold 21. Once in position, the locking cylinder 55 retracts, causing the hook 54 to rotate relative to the tailstock 53, thereby locking the hook head 541 on the hook 54 with the middle mold 21. Then, the second hydraulic cylinder 531 extends outward under pressure, driving the side mold 6 to press tightly against the middle mold 21. This ensures a tight connection between the side mold 6 and the middle mold 21.

[0069] Preferably, two hooks 54 are rotatably connected to the tailstock 53. The middle of the two hooks 54 is connected by a connecting plate 542. An elongated hole 543 is formed in the middle of the connecting plate 542. The length direction of the elongated hole 543 is parallel to the movement direction of the movable rod of the second hydraulic cylinder 531. The piston rod of the clamping cylinder 55 is connected to the elongated hole 543. The piston diameter of the second hydraulic cylinder 531 is larger than the piston diameter of the first hydraulic cylinder 513. The stroke of the first hydraulic cylinder 513 is greater than the stroke of the second hydraulic cylinder 531. The movement direction of the piston rod of the first hydraulic cylinder 513 is parallel to the length direction of the sliding guide rail 511. The connecting plate 542 and the piston rod of the clamping cylinder 55 are connected by a connector passing through the elongated hole 543. When the second hydraulic cylinder 531 is pressurized and extended, the piston rod of the clamping cylinder 55 can move laterally relative to the hooks 54, while ensuring that the hook head 541 can clamp the middle mold 21.

[0070] Preferably, the mounting base 52 has a first mounting plate 521, a second mounting plate 522, and a third mounting plate 523 that are perpendicular to each other.

The mounting base 52 has a mounting hole 524 for locking the side mold 6, and the mounting hole 524 is formed on the side of the third mounting plate 523 opposite to the clamping cylinder 55. This makes the structure of the mounting base 52 more stable.

[0071] The present invention also provides a method for operating a toilet production line, which further includes the following steps:

[0072] ① The middle mold 21 is lowered under the drive of the second lifting cylinder 13, so that the middle mold 21 contacts the bottom mold, the side mold 6 is closed and fixed, and the upper mold 11 is lowered to close and pressurize;

[0073] ② Tilt the mold cavity (i.e., tilt the upper mold, middle mold, lower mold and side mold after mold closing) with an inclination range of 0-30 degrees, and inject grout from the lowest point, waiting for the toilet blank 300 to be formed; while waiting for the toilet blank 300 to be formed, the track in the middle of the trolley track 8 is folded to form a transverse channel 88. At this time, the moving trolley 7 is located on the trolley track 8 on the side close to the conveyor belt 200;

[0074] ③ The upper mold 11 rises first, creating a small gap between the upper mold 11 and the middle mold 21. The side mold 6 disengages and retracts. The middle mold 21, the upper mold 11, and the toilet blank 300 rise together. The moving trolley 7 enters, the vacuum of the middle mold 21 is closed, and air is pumped to demold the toilet blank 300. Afterwards, the middle mold 21 and the upper mold 11 continue to rise, with the lower end of the middle mold 21 being higher than the toilet blank 300.

[0075] ④ The moving trolley 7 carries the toilet blank 300 away from the grouting machine 10;

[0076] ⑤ The lifting device 9 of the mold transfer device 700 transfers the toilet blank 300 on the moving trolley 7 together with the pallet 75 to the conveyor belt 200;

[0077] ⑥ The pallet 75 is conveyed along the conveyor belt 200.

[0078] Compared with the prior art, the present invention achieves the demolding and transfer of toilet blank 300 by arranging multiple sets of grouting machines 10 side by side and matching each with a demolding and transfer device 700. Moreover, a foldable structure is set in the middle of the trolley track 8, which can form a transverse channel 88 in the middle of the trolley track 8 when needed, thereby improving the efficiency of the toilet blank 300 production process.

[0079] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
