Description

Technical Field

[0001] This utility model relates to the field of sanitary ceramics production technology, and in particular to an automatic water suction device for high-pressure formed water tank blanks. Background Technology

[0002] Currently, sanitary ceramic toilet tanks are usually produced by high-pressure molding machines. During the demolding process, some water will remain at the bottom of the tank blank. This water needs to be cleaned up in time to prevent it from being sucked into the bottom of the tank blank, causing the bottom to soften and become damaged.

[0003] Workers often use sponges to absorb the water accumulated at the bottom of the billet, but this is a lot of work, inefficient, and the manual operation is prone to collisions with the billet, which can even damage the billet. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the present invention provides an automatic water suction device for high-pressure formed water tank blanks.

[0005] The automatic water suction device for high-pressure formed water tank blanks provided by this utility model adopts the following technical solution:

[0006] An automatic water suction device for high-pressure molded water tank blanks includes a main frame, a water suction mechanism, and a lifting mechanism. The lifting mechanism includes a mounting plate fixed to the top of the main frame. A cylinder is vertically mounted on the mounting plate. The piston rod of the cylinder passes through the mounting plate and is connected to a movable crossbeam at its bottom end. A limiting seat is slidably connected to the movable crossbeam along its length. The limiting seat includes a limiting tube with a deformation joint. The water suction mechanism includes a water suction pump, a vacuum tank, a water suction pipe, and a water suction head with a sponge block connected in sequence. The water suction head is located at the bottom end of the water suction pipe, and the water suction pipe is vertically clamped and fixed inside the limiting tube.

[0007] By adopting the above technical solution, the lifting mechanism controls the water suction mechanism to extend into the water tank blank to suck water, which improves the water suction efficiency, reduces the workload of the staff, and reduces the risk of the blank being accidentally damaged. If the model of the water tank blank changes, the horizontal height of the water suction pipe can be adjusted by the limiting tube, and the horizontal position of the water suction pipe can be adjusted by the limiting seat. The vacuum tank sucks in the water in the water tank blank and discharges the air to form a vacuum environment, avoiding the loss of water suction pressure due to water and air mixing.

[0008] Optionally, the limiting seat includes a limiting plate that fits onto the moving crossbeam, a limiting tube that is fixed to the limiting plate, a waist-shaped sliding hole and a limiting hole that are opened along the length of the moving crossbeam, a water suction pipe that passes through the sliding hole, and a limiting bolt for fixing the limiting plate that passes through the limiting hole.

[0009] By adopting the above technical solution, the horizontal position of the water suction pipe can be changed by moving the limiting plate, and the limiting plate can be fixed by the limiting bolt, making the operation simple.

[0010] Optionally, the water suction head includes a lower end plate fixed to the water suction pipe. The lower end plate has a hole communicating with the water suction pipe. A sealing ring, a connecting plate, and a sponge block are connected sequentially to the bottom of the lower end plate. Several water-permeable holes are evenly provided on the connecting plate.

[0011] By adopting the above technical solution, the sponge absorbs water and enters the water absorption tube through the water-permeable holes. The sealing ring effectively improves the airtightness, thereby improving the water absorption effect.

[0012] Optionally, a guide shaft is vertically fixed to the top surface of the movable crossbeam, and an oil-free bushing is vertically fixed to the mounting plate, with the guide shaft sliding through the oil-free bushing.

[0013] By adopting the above technical solution, the guide shaft and oil-free bushing work together to guide the movement, improving the stability of the moving crossbeam during the up and down movement. The structure of the cylinder equipped with the guide shaft has the advantage of lower cost compared to the cylinder with its own guide rod.

[0014] Optionally, a retaining ring is fixed to the guide shaft, and a gap is provided between the retaining ring and the moving crossbeam.

[0015] By adopting the above technical solution, the fixing ring has the effect of limiting the upward movement distance of the moving crossbeam, thus avoiding squeezing and damage at the top connection of the water suction pipe.

[0016] Optionally, two guide shafts are provided and symmetrically arranged on both sides of the cylinder, and a fixing plate is installed between the top ends of the two guide shafts.

[0017] By adopting the above technical solution, the symmetrical arrangement of the two guide axes further improves the stability of the moving crossbeam during its up-and-down movement.

[0018] Optionally, the main frame is rectangular and includes multiple interconnected vertical and horizontal bars, with the mounting plate bolted between two horizontal bars located at the top of the main frame.

[0019] By adopting the above technical solution, it is easy to adjust the position of the mounting plate on the main frame according to the usage.

[0020] Optionally, the water pump is connected to the vacuum tank via a hose 1. The vacuum tank is connected to a hose 2, which has a smaller diameter than the hose 1. A hose 3 is connected to the hose 2. The hose 3 is fixed to the main frame and extends upward. The hose 3 is connected to the water suction pipe via a connecting elbow.

[0021] By adopting the above technical solution, an effective water absorption path is formed, and the smaller diameter of the second hose compared to the first hose facilitates greater suction.

[0022] Optionally, a magnetic induction switch is installed on the cylinder. When the cylinder piston rod retracts upward to the correct position, the magnetic induction switch detects the signal and sends it back to the conveyor line, which then continues to transport the water tank blank.

[0023] By adopting the above technical solution, the water suction operation and the conveying of the water tank blank can be automated, and the two are linked together, which improves the overall work efficiency and reduces the cost of manual control.

[0024] In summary, this utility model has at least one of the following beneficial technical effects:

[0025] 1. The lifting mechanism controls the water suction mechanism to extend into the water tank blank body to suck water, which improves the water suction efficiency, reduces the workload of the staff, and reduces the risk of the blank body being accidentally damaged.

[0026] 2. If the model of the water tank blank changes, the horizontal height of the suction pipe can be adjusted by the limiting tube, and the horizontal position of the suction pipe can be adjusted by the limiting seat.

[0027] 3. The vacuum tank draws water from the water tank blank and expels air to form a vacuum environment, preventing water and air from mixing and causing a loss of water absorption pressure. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 The present invention will be described in further detail below.

[0034] This utility model discloses an automatic water suction device for high-pressure molded water tank blanks. (Refer to...) Figure 1 The automatic water suction device for high-pressure formed water tank blanks includes a main frame 1, a water suction mechanism 2, and a lifting mechanism 3.

[0035] Reference Figure 1 The main frame 1 is a rectangular frame made of aluminum profiles, including vertical rods 10 and horizontal rods 11 bolted together. The vertical rods 10 are fixed to the ground with anchor bolts. The main frame 1 is convenient for transportation and on-site assembly. The water tank conveying line passes through the inside of the main frame 1. The water suction mechanism 2 includes a water suction pump 20, which is an air pump for continuous operation. The water suction pump 20 is connected to a first hose 21, which is connected to a vacuum tank 22 with the connection point located at the top of the vacuum tank 22. The vacuum tank 22 is connected to a second hose 23 with the connection point located at the bottom side of the vacuum tank 22. The vacuum tank 22 draws water from the water tank blank through the second hose 23 and discharges air through the first hose 21, forming a vacuum environment and preventing water and air from mixing and losing water suction pressure.

[0036] Reference Figure 1 The vacuum tank 22 is equipped with a solenoid valve at its drain outlet, which is programmed to discharge water from the vacuum tank 22 at regular intervals. The diameter of hose 23 is smaller than that of hose 21 to provide a better suction environment. Hose 23 is connected to two hoses 24 via a T-joint. Hose 24 is fixed to the vertical rod 10 and extends upwards. Hose 24, hose 23, and hose 21 are all steel wire plastic hoses. Hose 24 is connected to a vertically arranged suction pipe 25 via a connecting elbow. The suction pipe 25 is a rigid straight pipe, and a suction head 26 is installed at the bottom of the suction pipe 25 to absorb water accumulated at the bottom of the water tank blank.

[0037] Reference Figure 2 and Figure 3 The suction head 26 includes a lower end plate 260 fixed to the bottom of the suction pipe 25. A circular hole communicating with the suction pipe 25 is opened in the middle of the lower end plate 260. From top to bottom, a sealing ring 261, a connecting plate 262, and a sponge block 263 are sequentially installed on the bottom of the lower end plate 260. Several 5mm diameter permeable holes are evenly opened on the connecting plate 262 to facilitate water absorption. The sealing ring 261 is positioned between the lower end plate 260 and the connecting plate 262, achieving an airtight seal, maintaining a negative pressure environment, and improving the water absorption effect.

[0038] Reference Figure 1 and Figure 2The lifting mechanism 3 includes a mounting plate 30 bolted between two crossbars 11 located at the top of the main frame 1. The position of the mounting plate 30 on the main frame 1 can be adjusted arbitrarily according to the position of the conveyor line. A cylinder 31 is vertically mounted on the top surface of the middle part of the mounting plate 30. A magnetic induction switch is installed on the cylinder 31. When the piston rod of the cylinder 31 retracts upward to the end, the magnetic induction switch detects this and sends feedback to the conveyor line control system, which can then control the conveyor line to continue working and output the water tank blank after water absorption. The piston rod of the cylinder 31 passes downward through the mounting plate 30 and is connected to a horizontally set moving crossbeam 33 through a floating joint 32. Two oil-free bushings 34 are vertically fixed to the top surface of the mounting plate 30, and the two oil-free bushings 34 are symmetrically arranged on both sides of the cylinder 31.

[0039] Reference Figure 2 Two guide shafts 35 are vertically fixed to the top surface of the movable crossbeam 33. The two guide shafts 35 are slidably inserted into two oil-free bushings 34. A U-shaped fixing plate 36 is installed at the top of the two guide shafts 35 to enable the two guide shafts 35 to move synchronously. A fixing ring 37 is fixedly installed on the guide shaft 35 for moving and abutting against the mounting plate 30. A set distance is left between the fixing ring 37 and the movable crossbeam 33 to prevent the elbow connecting the water suction pipe 25 and the flexible hose 24 from being squeezed and damaged when the movable crossbeam 33 rises.

[0040] Reference Figure 2 and Figure 4 Each end of the movable crossbeam 33 is equipped with a limiting seat 38 for fixing the suction pipe 25. The limiting seat 38 includes a limiting plate 380 that fits against the top surface of the movable crossbeam 33. A limiting tube 381 with an expansion joint is fixed to the top surface of the limiting plate 380. The suction pipe 25 passes through the limiting tube 381 and the limiting plate 380. The suction pipe 25 can be fixed by tightening the limiting tube 381 with screws. The setting of the limiting tube 381 facilitates the adjustment of the horizontal height of the suction pipe 25.

[0041] Reference Figure 4 A sliding hole 330 and a limiting hole 331 are provided on the movable crossbeam 33 at the position corresponding to the limiting seat 38. The width of the sliding hole 330 is larger than that of the limiting hole 331. There are two limiting holes 331, which are symmetrically arranged on both sides of the sliding hole 330. Both the sliding hole 330 and the limiting hole 331 are oblong holes and extend along the length of the movable crossbeam 33. The water suction pipe 25 passes through the sliding hole 330, and the limiting bolt 382 for fixing the limiting plate 380 passes through the limiting hole 331. The distance between the two water suction pipes 25 can be changed by moving the limiting seat 38 to adapt to different models of water tank blanks.

[0042] The implementation principle of the automatic water suction device for high-pressure formed water tank blanks in this embodiment is as follows: The water tank blank is transported to the water suction station via a conveyor line. The cylinder 31 extends, driving the suction pipe 25 and the suction head 26 into the interior of the water tank blank. The suction pump 20 is started, generating negative pressure, thereby sucking water from the bottom of the water tank blank into the vacuum tank 22 through the sponge block 263 and discharging it periodically. If the model of the water tank blank changes, the horizontal height of the suction pipe 25 can be adjusted adaptively via the limiting pipe 381, and the spacing between the suction pipes 25 can be adjusted via the limiting seat 38. The lifting mechanism 3 controls the suction mechanism 2 to extend into the water tank blank for water suction, improving the water suction efficiency, reducing the workload of the workers, and reducing the risk of the blank being accidentally damaged.

[0043] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
