Description

Technical Field

[0001] This application relates to the field of filling machine technology, and more specifically, to a filling machine for producing polyurethane ink. Background Technology

[0002] In the production of polyurethane inks, traditional manual filling relies on the operator's experience to control the flow rate, which has the problem of low metering accuracy. This can easily lead to large weight deviations in single barrels, affecting the consistency of product quality. Residual ink is easy to adhere to the inside of the storage barrel and is difficult to recover, resulting in ink waste. It also increases the subsequent maintenance and cleaning work. Ink barrels need to be frequently lifted, positioned, and moved and replaced, which is labor-intensive. Furthermore, the separation of the mixing process and the filling process is inefficient. In view of this, we propose a filling machine for polyurethane ink production. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a filling machine for polyurethane ink production, which solves the technical problems mentioned in the background art. It realizes quantitative extraction and valve opening and closing control through the linkage of electric cylinder and pneumatic cylinder, achieving accurate metering, small filling error, and good product quality consistency. The L-shaped scraper and stirring blades ensure uniform stirring of ink in the storage tank, ensuring ink flowability and thoroughly removing residual ink from the inner wall of the storage tank, realizing a self-cleaning process. The end cap is equipped with a flip-top structure to ensure zero leakage during transportation and filling, reducing material loss. The screw-driven pallet lifts and lowers smoothly, adapting to the precise docking of different sized barrels and T-shaped filling tubes. Moreover, the smooth lifting and lowering operation of the pallet reduces the labor intensity of manual handling and loading, and improves production efficiency.

[0005] 2. Technical Solution

[0006] This application provides a filling machine for polyurethane ink production, comprising: a T-shaped base; a T-shaped support shell fixedly mounted on the upper surface of the T-shaped base; an electric cylinder and a cross-shaped tube fixedly mounted on the T-shaped support shell; a storage tank fixedly connected to the upper end of the cross-shaped tube; an end cap detachably mounted on the upper end of the storage tank; a stirring mechanism mounted on the end cap for stirring the polyurethane ink stored in the storage tank evenly and cleaning the inner wall of the storage tank; a sealing column rotatably mounted inside the cross-shaped tube; a circular hole opened in the middle of the sealing column; a metering cylinder and a T-shaped filling tube fixedly connected to the cross-shaped tube; a movable rod of the electric cylinder slidably inserted into the metering cylinder and fixedly connected to a piston structure; a ball valve rotatably mounted on the T-shaped filling tube; a switching mechanism mounted on the housing of the electric cylinder for driving the rotation of the sealing column and the ball valve; a lifting mechanism mounted on the T-shaped base and drivenly connected to a pallet; multiple rotating rollers rotatably mounted on the pallet for placing ink barrels; and a control cabinet fixedly mounted on the bottom surface of the pallet.

[0007] By adopting the above technical solution, the filling machine uses a T-shaped base and a T-shaped support shell to form a support frame structure. The electric cylinder and the pneumatic cylinder work together to achieve quantitative extraction and valve opening and closing control, realizing accurate measurement, small filling error, and good product quality consistency. The L-shaped scraper and the stirring blades ensure that the ink in the storage tank is stirred evenly, ensuring the fluidity of the ink and thoroughly removing residual ink from the inner wall of the storage tank, realizing a self-cleaning process. The end cap is equipped with a flip-top structure to ensure zero leakage during transportation and filling, reducing material loss. The screw-driven pallet lifts and lowers smoothly, adapting to the precise docking of different sized barrels and T-shaped filling tubes. Moreover, the smooth lifting and lowering operation of the pallet reduces the labor intensity of manual handling and loading, and improves production efficiency.

[0008] Optionally, three self-locking casters are rotatably mounted on the T-shaped base, and the three self-locking casters are arranged in a triangular pattern.

[0009] By adopting the above technical solution, three self-locking casters achieve a three-point stable support structure, which, together with the braking device, enables the equipment to be positioned and fixed on uneven workshop floors.

[0010] Optionally, a handrail is fixedly provided on the T-shaped support shell, and a cross plate is slidably installed on the T-shaped support shell. The lifting mechanism includes a second motor and a telescopic rod. The slide rod of the telescopic rod is fixedly sleeved with the cross plate, and the top end of the slide rod of the telescopic rod is fixedly connected to a support plate. The guide cylinders of the second motor and the telescopic rod are both fixedly installed on the T-shaped base. A lead screw is fixedly provided at the output end of the second motor, and the lead screw is threadedly connected to the cross plate.

[0011] By adopting the above technical solution, when the ink bucket needs to be moved onto the pallet, the motor drives the lead screw to rotate, causing the horizontal plate to drive the slide bar to slide along the guide cylinder, so that the pallet can lift and lower the ink bucket, which facilitates the handling of ink buckets, reduces labor intensity, and can adapt to the filling work of ink buckets of different sizes through the pallet lifting operation.

[0012] Optionally, the switching mechanism includes a cylinder, which is fixedly mounted on the housing of the electric cylinder. The piston rod of the cylinder is fixedly provided with a connecting frame, which is slidably mounted on a T-shaped support shell. The connecting frame is fixedly connected to a rack and a rack, which is meshed with a gear and is fixedly connected to a sealing column. The rack is meshed with a gear and is fixedly connected to the valve stem of the ball valve.

[0013] By adopting the above technical solution, the piston rod of the cylinder can drive the connecting frame to slide along the T-shaped support shell during the extension and retraction process. Due to the meshing connection between rack one and gear one, and rack two and gear two, the sealing column and ball valve can rotate synchronously. When the sealing column in the cross-shaped tube connects to the storage tank through the round hole, the ball valve of the T-shaped filling tube is in a closed and blocked state. Conversely, when the sealing column in the cross-shaped tube blocks the storage tank, the ball valve of the T-shaped filling tube is in an open and conductive state.

[0014] Optionally, the end cap is rotatably hinged with a flip cover.

[0015] By adopting the above technical solution, the end cap is designed to facilitate ink filling by flipping it over. The end cap, with a sealing ring structure installed at the end cap, allows for closed operation of the storage tank port, preventing dust from entering.

[0016] Optionally, the stirring mechanism includes a motor, which is fixedly installed on the upper surface of the end cap. The output shaft of the motor extends movably into the storage tank and is fixedly connected to three horizontal bars. The horizontal bars are fixedly connected to multiple vertical plates and an L-shaped scraper, which is attached to the inner wall of the storage tank.

[0017] By adopting the above technical solution, the motor drives three horizontal bars to rotate, which in turn drives the L-shaped scraper and multiple vertical plates to rotate. The vertical plates stir the polyurethane ink in the storage tank evenly, maintaining the flowability of the polyurethane ink. The L-shaped scraper rotates along the inner wall of the storage tank, enabling the inner wall of the storage tank to self-clean and preventing the polyurethane ink from adhering to the inner wall of the storage tank.

[0022] 3. The screw-driven pallet lifts and lowers smoothly, adapting to the precise docking of different sized barrels and T-shaped filling tubes. The smooth lifting and lowering operation of the pallet reduces the labor intensity of manual handling and loading / unloading, and improves production efficiency. Attached Figure Description

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 4This application provides a filling machine for polyurethane ink production, comprising: a T-shaped base 1, a T-shaped support shell 2 fixedly mounted on the upper surface of the T-shaped base 1, an electric cylinder 3 and a cross-shaped tube 63 fixedly mounted on the T-shaped support shell 2, a storage tank 6 fixedly connected to the upper end of the cross-shaped tube 63, an end cap 61 detachably mounted on the upper end of the storage tank 6, a stirring mechanism 7 mounted on the end cap 61 for stirring the polyurethane ink stored in the storage tank 6 evenly and cleaning the inner wall of the storage tank 6, a sealing column 64 rotatably mounted inside the cross-shaped tube 63, a circular hole 641 opened in the middle of the sealing column 64, a metering cylinder 4 and a T-shaped filling tube 65 fixedly connected to the cross-shaped tube 63, a piston structure fixedly connected to the moving rod of the electric cylinder 3 slidably inserted into the metering cylinder 4, and a ball valve 66 rotatably mounted on the T-shaped filling tube 65, and a switching mechanism 5 mounted on the housing of the electric cylinder 3 for driving the sealing column 64 and the ball valve. The filling machine features a 66-rotation mechanism. A lifting mechanism 8 is mounted on the T-shaped base 1, which is connected to a pallet 9. Multiple rotating rollers 91 are mounted on the pallet 9 to hold ink barrels. A control cabinet 10 is fixedly mounted on the bottom of the pallet 9. The filling machine uses the T-shaped base 1 and T-shaped support shell 2 to form a support frame structure. The electric cylinder and the pneumatic cylinder work together to achieve quantitative extraction and valve opening and closing control, achieving accurate measurement, small filling error, and good product quality consistency. The L-shaped scraper, together with the stirring blades, ensures uniform agitation of the ink in the storage tank, ensuring ink flowability and thoroughly removing residual ink from the inner wall of the storage tank, achieving a self-cleaning process. The end cap is equipped with a flip-top structure to ensure zero leakage during transportation and filling, reducing material loss. The screw-driven pallet lifts and lowers smoothly, adapting to the precise docking of different sized barrels and T-shaped filling tubes. The smooth lifting and lowering operation of the pallet reduces the labor intensity of manual handling and improves production efficiency.

[0030] Reference Figure 1 and Figure 2 Three self-locking casters 11 are rotatably mounted on the T-shaped base 1. The three self-locking casters 11 are arranged in a triangle and achieve a three-point stable support structure. With the help of the braking device, the equipment can be positioned and fixed on uneven workshop floors.

[0031] Reference Figure 1 and Figure 2A handrail 21 is fixedly provided on the T-shaped support shell 2, and a horizontal plate 22 is slidably installed on the T-shaped support shell 2. The lifting mechanism 8 includes a second motor 81 and a telescopic rod 83. The slide rod of the telescopic rod 83 is fixedly sleeved with the horizontal plate 22, and the top of the slide rod of the telescopic rod 83 is fixedly connected to the support plate 9. The guide tubes of the second motor 81 and the telescopic rod 83 are both fixedly installed on the T-shaped base 1. The output end of the second motor 81 is fixedly provided with a lead screw 82, which is threadedly connected to the horizontal plate 22. When the ink bucket needs to be moved onto the support plate 9, the second motor 81 drives the lead screw 82 to rotate, causing the horizontal plate 22 to drive the slide rod to slide along the guide tube, so that the support plate 9 can move the ink bucket to lift and lower, which facilitates the handling of ink buckets, reduces labor intensity, and can adapt to the filling work of ink buckets of different specifications through the lifting and lowering operation of the support plate 9.

[0032] Reference Figure 2 and Figure 3 The switching mechanism 5 includes a cylinder 51, which is fixedly mounted on the housing of the electric cylinder 3. A connecting frame 52 is fixedly mounted on the piston rod of the cylinder 51. The connecting frame 52 is slidably mounted on the T-shaped support shell 2. A rack 1 53 and a rack 2 54 are fixedly connected to the connecting frame 52. The rack 1 53 is meshed with a gear 1 642, which is fixedly connected to the sealing column 64. The rack 2 54 is meshed with a gear 2 661, which is fixedly connected to the valve stem of the ball valve 66. During the extension and retraction of the piston rod of the cylinder 51, it can... The connecting frame 52 slides along the T-shaped support shell 2. Due to the meshing connection between rack 53 and gear 642, and rack 54 and gear 661, the sealing column 64 and ball valve 66 can rotate 90° synchronously. When the sealing column 64 in the cross-shaped tube 63 connects to the storage tank 6 through the round hole 641, the ball valve 66 of the T-shaped filling tube 65 is in a closed and blocked state. Conversely, when the sealing column 64 in the cross-shaped tube 63 blocks the storage tank 6, the ball valve 66 of the T-shaped filling tube 65 is in an open and conductive state.

[0033] Reference Figure 1 and Figure 2 The end cap 61 is hinged to a flip cover 62. The flip cover 62 facilitates the addition of ink. The end cap 61 is equipped with a sealing ring structure to ensure that the storage tank 6 port is closed during operation, preventing dust from entering.

[0034] Reference Figure 2 and Figure 4The stirring mechanism 7 includes a motor 71, which is fixedly mounted on the upper surface of the end cap 61. The output shaft of the motor 71 extends movably into the storage tank 6 and is fixedly connected to three horizontal bars 72. Each horizontal bar 72 is fixedly connected to multiple vertical plates 73 and an L-shaped scraper 74. The L-shaped scraper 74 is attached to the inner wall of the storage tank 6. The motor 71 drives the three horizontal bars 72 to rotate, which in turn drives the L-shaped scraper 74 and multiple vertical plates 73 to rotate. The vertical plates 73 stir the polyurethane ink in the storage tank 6 evenly, maintaining the flowability of the polyurethane ink. The L-shaped scraper 74 rotates along the inner wall of the storage tank 6, causing the inner wall of the storage tank 6 to self-clean and preventing the polyurethane ink from adhering to the inner wall of the storage tank 6.

[0035] Working principle: Open the flip cover 62, put the polyurethane ink into the storage tank 6, close the flip cover 62, start the motor 71 to drive the three horizontal bars 72 to rotate, which in turn drives the L-shaped scraper 74 and multiple vertical plates 73 to rotate. The vertical plates 73 stir the polyurethane ink in the storage tank 6 evenly, maintaining the flowability of the polyurethane ink. The L-shaped scraper 74 rotates along the inner wall of the storage tank 6, making the inner wall of the storage tank 6 self-cleaning, preventing the polyurethane ink from adhering to the inner wall of the storage tank 6, reducing the amount of maintenance and cleaning work. The piston rod of the cylinder 51 retracts, driving the connecting frame 52 to slide along the T-shaped support shell 2. Due to the meshing connection between rack 53 and gear 642, and rack 54 and gear 661, the sealing column 64 and ball valve 66 can rotate 90° synchronously, so that the sealing column 64 in the cross-shaped tube 63... When the storage tank 6 is connected through the round hole 641, the ball valve 66 of the T-shaped filling tube 65 is in a closed and sealed state. The piston is pulled back by the electric cylinder 3, so that the metering cylinder 4 can draw a certain amount of polyurethane ink from the storage tank 6. Then the piston rod of the cylinder 51 extends, so that the sealing column 64 closes to complete the rapid interception, and the ball valve 66 rotates to open. The piston is pushed by the electric cylinder 3 to move along the metering cylinder 4, so that the certain amount of polyurethane ink in the metering cylinder 4 is discharged through the T-shaped filling tube 65. The above actions are repeated to achieve the purpose of metered filling. The forward and reverse rotation of the motor 81 can make the lead screw 82 drive the horizontal plate 22 to slide along the T-shaped support shell 2. The telescopic rod 83 makes the tray 9 carry the ink barrel to rise at a constant speed to below the filling port. The tray 9 is equipped with a rotating roller 91 to facilitate the movement and replacement of new ink barrels.
