Description

Technical Field

[0001] The present invention relates to the technical field of discharging devices, and particularly to a discharging device for a heating tank. Background Art

[0002] A discharging device for a heating tank is a device used to control the discharge of the liquid material in the heating tank. It generally includes a discharge port, a valve, a heating element, and a control system. The heating element ensures that the gum remains at an appropriate temperature during discharging to prevent it from solidifying or adhering. The valve is used to precisely control the discharging speed and quantity to ensure uniform discharge of the liquid material. The control system can adjust the heating temperature and discharging parameters to meet the requirements of different gums. This device is widely used in industries such as chemical engineering, food, and pharmaceuticals to ensure efficient and stable discharging of the gum liquid material.

[0003] In the patent with the publication number CN216426752U, a heating type discharging device for a caprolactam liquid storage tank is disclosed, which includes a heating box. An inlet pipe is fixedly connected inside the upper end of the heating box, and a valve is fixedly connected in the middle of the inlet pipe. A movable plate is movably connected inside the lower ends of several groups of storage cavities. The upper and lower ends of the first connecting shaft are movably connected to the upper and lower ends inside the heating box through first bearings. The lower end of the first connecting shaft extends out of the heating box and is fixedly connected to the output end of a first motor. A discharge pipe is fixedly connected inside the left side of the lower end of the discharge box; the caprolactam liquid flowing out of the inlet pipe is evenly distributed in several groups of storage cavities. At the same time, under the heating action of the first heating strip, and then under the heating action of the second heating strip, the caprolactam liquid is always in a heated state and is discharged from the discharge pipe through the spiral stirring cylinder, so that the caprolactam liquid is heated during the discharging process. The operation is simple and the work efficiency is improved.

[0004] The existing technology has the following defects: It is impossible to adjust the inclination angle and opening size of the discharge pipe according to the viscosity of the liquid material: High-viscosity liquid materials have poor fluidity and are prone to clogging at the discharge port, resulting in slow or uneven discharging speed. Low-viscosity liquid materials have strong fluidity, and too fast discharging may cause splashing or waste. However, the existing devices generally have fixed inclination angles and opening sizes and cannot adapt to the fluidity of different liquid materials, which affects the discharging uniformity and product quality. Therefore, a structure that can adjust the inclination angle and opening size of the discharge pipe needs to be set up to achieve more precise discharging control. For high-viscosity liquid materials, increasing the opening and adjusting the inclination angle can improve the discharging efficiency and avoid clogging; for low-viscosity liquid materials, reducing the opening and adjusting the angle can prevent splashing and waste, achieving the effect of ensuring discharging uniformity and product quality.

[0005] Failure to clean the discharge pipe in time leads to blockage: The viscous material liquid has strong adhesiveness and is easy to stick to the tank wall or inside the pipeline. Moreover, the viscous material liquid is prone to solidify after cooling, resulting in blockage of the pipeline or valve. If the discharge pipe is not cleaned in time, the residual material liquid in the discharge pipe will deteriorate or contaminate subsequent products, affecting product quality and consistency. In addition, it will increase the equipment load, lead to an increase in energy consumption, and even cause equipment failures, increasing the maintenance cost. Therefore, a structure for cleaning the discharge pipe in time after each discharge is required to achieve continuous and stable operation, significantly improve production efficiency, and achieve the effect of ensuring product quality and consistency. Summary of the Invention

[0006] In view of the problems in the prior art that the inclination angle and opening size of the discharge pipe cannot be adjusted according to the viscosity of the material liquid and the discharge pipe cannot be cleaned in time, resulting in blockage, etc., a discharge device for a heating tank is proposed.

[0007] On the one hand, the present application provides a discharge device for a heating tank, and its purpose is: through the arranged inclined discharge mechanism and discharge mechanism, more accurate discharge control can be achieved. For highly viscous material liquid, increasing the opening and adjusting the inclination angle can improve the discharge efficiency and avoid blockage; for low-viscosity material liquid, reducing the opening and adjusting the angle can prevent splashing and waste, achieving the effect of ensuring discharge uniformity and product quality. At the same time, a structure for cleaning the discharge pipe in time after each discharge is realized, achieving continuous and stable operation, significantly improving production efficiency, and achieving the effect of ensuring product quality and consistency.

[0008] The technical solution of the present invention is: A discharge device for a heating tank includes a tank body, an inclined discharge mechanism, a swing assembly, and a discharge mechanism arranged on one side of the tank body. The inclined discharge mechanism is used for inclined discharge and controlling the valve switch. The swing assembly is used for adjusting the inclination angle of the inclined discharge mechanism. The discharge mechanism controls the opening and closing of the discharge port according to the swing amplitude of the swing assembly. The inclined discharge mechanism includes a fixing component for fixing the valve, a valve component for controlling the valve switch, and a discharge component for discharging materials; The discharge component includes a discharge pipe, and a discharge port is arranged below the discharge pipe. The discharge mechanism includes a discharge outer cover fixed outside the discharge pipe. The opening position of the discharge outer cover is aligned with the discharge port. An opening and closing component is arranged between the discharge outer cover and the discharge pipe, and the opening and closing component is used for controlling the opening and closing of the discharge port.

[0009] By adopting the above scheme, the inclination angle of the discharge pipe is adjusted according to the viscosity of the liquid feed through the inclined discharge mechanism and the discharge mechanism. At the same time, the inclination angle of the discharge pipe drives the discharge mechanism to adjust the size of the discharge port, thereby achieving more precise discharge control. For high-viscosity liquid feed, increasing the opening and adjusting the inclination angle can improve the discharge efficiency and avoid blockage; for low-viscosity liquid feed, reducing the opening and adjusting the angle can prevent splashing and waste, thereby ensuring the uniformity of discharge and product quality.

[0010] Furthermore, the opening and closing assembly includes an opening and closing clamp block slidably connected between the discharge outer cover and the discharge pipe, the opening of the opening and closing clamp block is the same size as the discharge port, a plurality of return springs are fixedly connected between one end of the opening and closing clamp block and the inner wall of the discharge outer cover, a plurality of connecting ropes are fixedly connected to one end of the opening and closing clamp block away from the return springs, and a scraper is fixedly connected to the side of the opening of the opening and closing clamp block close to the connecting ropes.

[0011] Furthermore, the outer wall of the tank body is fixedly connected with a cross frame, the inner wall of the cross frame is rotatably connected with a rocking block, and the ends of the plurality of connecting ropes away from the clamping block are fixedly connected to the bottom of the rocking block.

[0012] By adopting the above scheme, through the setting of the opening and closing components, when the viscosity of the slurry is relatively high, the multiple connecting ropes at the bottom of the rocking block pull the opening and closing clamp block in the discharge cover so that the opening of the opening and closing clamp block is aligned with the discharge port. At this time, the discharge port, the opening of the opening and closing clamp block and the opening of the discharge cover are connected, and are all at the maximum opening size, which is convenient for discharging slurry with relatively high viscosity. When the viscosity of the slurry is relatively low, the connecting rope will loosen a part of the opening and closing clamp block, so that the opening of the opening and closing clamp block is offset from the discharge port under the reset of multiple reset springs. At this time, the discharge port can be adjusted to facilitate the discharge of slurry with relatively low viscosity.

[0013] Furthermore, the end of the discharge pipe away from the tank body is fixedly connected to a servo motor, the output shaft sleeve of the servo motor is provided with an extrusion screw, the extrusion screw is arranged inside the discharge pipe, and the end of the discharge pipe close to the tank body is fixedly connected to a ball valve cover, and the inner wall of the ball valve cover is provided with a through hole.

[0014] Furthermore, the valve assembly includes a one-way ball valve rotatably connected to the inner wall of the ball valve cover, the outer wall of the one-way ball valve is fixedly connected to a bearing, the outer wall of the bearing is rotatably connected to the inner wall of the penetration hole, one end of the bearing is fixedly connected to a micro motor, and the inner wall of the one-way ball valve is provided with a feeding hole.

[0015] With the above - mentioned solution, by means of the arranged discharging component and valve component, after the adjustment of the inclination angle and the opening size is completed, the micro - motor can be operated. The output shaft of the micro - motor drives the one - way ball valve to rotate in the ball valve cover through the bearing. At the same time, the misalignment degree between the material - passing hole and the discharging port can be used to adjust the size of the discharging port. Then, the servo - motor is operated. The output shaft of the servo - motor drives the extrusion screw to rotate in the discharging pipe to convey the liquid material, and at the same time, the servo - motor can adjust the conveying speed.

[0016] Further, the fixing component includes a fixing outer shell fixedly connected to the outer wall of the tank body. A limiting groove is formed on the inner wall of the fixing outer shell. The outer wall of the bearing is slidably connected to the inner wall of the limiting groove. A discharging port is formed on the inner wall of the fixing outer shell. When the one - way ball valve is in the open state, the discharging port is in a communicating state with the tank body, the material - passing hole and the discharging pipe.

[0017] With the above - mentioned solution, by means of the arranged fixing component, when the one - way ball valve is in the open state, the liquid material can enter the discharging pipe through the discharging port and the material - passing hole, and the liquid material in the discharging pipe can also flow back to the tank body.

[0018] Further, the swinging component includes an arc - shaped frame fixedly connected to the outer wall of the tank body. A swinging groove is formed on the inner wall of the arc - shaped frame. The outer wall of the discharging pipe is slidably connected to the inner wall of the swinging groove. Two symmetrically arranged guiding grooves are formed on the inner wall of the arc - shaped frame. Guide bars are slidably connected to the inner walls of the two guiding grooves. An arc - shaped rack is connected between the two guide bars. The upper end of the arc - shaped rack is fixedly connected with an arc - shaped support block, and the arc - shaped support block is arranged below the discharging pipe.

[0019] Further, the arc - shaped rack is slidably connected inside the arc - shaped frame. A rotary cylinder is arranged on one side of the arc - shaped frame. A driving gear is sleeved on the output end of the rotary cylinder, and the driving gear meshes with the arc - shaped rack.

[0020] With the above - mentioned solution, by means of the arranged swinging component, when the viscosity of the liquid material is relatively high, the rotary cylinder is operated. The output end of the rotary cylinder drives the arc - shaped rack to slide in the arc - shaped frame through the driving gear. The discharging pipe is supported by the arc - shaped support block to swing in the swinging groove, and is limited by the guide bars and the guiding grooves. When the discharging pipe is at the bottom of the swinging groove, the inclination angle is the largest. When the viscosity of the liquid material is relatively low, similarly, the swinging component is operated to make the discharging pipe in a position below the swinging groove, not at the bottom, so as to adjust the inclination angle. After one discharging is completed, the rotary cylinder is operated in the reverse direction to make the discharging pipe swing to the top of the swinging groove to provide an inclination angle for the back - flow.

[0021] The beneficial effects of the present invention: 1. Through the inclined discharge mechanism and the discharging mechanism, the inclination angle of the discharge pipe is adjusted according to the viscosity of the liquid. At the same time, the inclination angle of the discharge pipe drives the discharging mechanism to adjust the size of the discharge port, which can achieve more precise discharging control. For high-viscosity liquid, increasing the opening and adjusting the inclination angle can improve the discharging efficiency and avoid blockage; for low-viscosity liquid, reducing the opening and adjusting the angle can prevent splashing and waste, so as to ensure the uniformity of discharging and product quality.

[0022] 2. Through the opening and closing components that are set, when the viscosity of the slurry is high, the multiple connecting ropes at the bottom of the swing block pull the opening and closing clamp block in the discharge cover to align the opening of the opening and closing clamp block with the discharge port. At this time, the discharge port, the opening of the opening and closing clamp block and the opening of the discharge cover are connected, and are all at the maximum opening size, which is convenient for discharging slurry with high viscosity. When the viscosity of the slurry is low, the connecting rope will loosen a part of the opening and closing clamp block, so that the opening of the opening and closing clamp block is staggered with the discharge port under the reset of multiple reset springs. At this time, the discharge port can be adjusted to facilitate the discharge of slurry with low viscosity, thereby playing a role in adjusting the discharge efficiency.

[0023] 3. After the inclination angle and the opening size are adjusted by the set discharge assembly and valve assembly, the micro motor can be operated. The output shaft of the micro motor drives the one-way ball valve to rotate in the ball valve cover through the bearing. At the same time, the misalignment degree between the feed hole and the discharge port can adjust the size of the discharge port. Then the servo motor is operated. The output shaft of the servo motor drives the extrusion screw to rotate in the discharge pipe to convey the material liquid. At the same time, the servo motor can adjust the conveying speed to adjust the discharge efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification.

[0027] Refer to Figure 1 - Figure 11 , a heating tank discharging device is provided, which includes a tank body 1, an inclined discharging mechanism 2, a swing component 3 and a discharging mechanism 4 arranged on one side of the tank body 1. The inclined discharging mechanism 2 is used for inclined discharging and controlling the valve opening and closing. The swing component 3 is used for adjusting the inclination angle of the inclined discharging mechanism 2. The discharging mechanism 4 controls the opening and closing of the discharging port according to the swing amplitude of the swing component 3. The inclined discharging mechanism 2 includes a fixing component 21 for fixing the valve, a valve component 22 for controlling the valve opening and closing, and a discharging component 23 for discharging materials.

[0028] Refer to Figure 3 - Figure 8 , the discharging component 23 includes a discharge pipe 231, and a discharging port is arranged below the discharge pipe 231. The discharging mechanism 4 includes a discharging outer cover 43 fixed on the outer side of the discharge pipe 231. The opening position of the discharging outer cover 43 is aligned with the discharging port. An opening and closing component 44 is arranged between the discharging outer cover 43 and the discharge pipe 231. The opening and closing component 44 is used for controlling the opening and closing of the discharging port.

[0029] Specifically, the swing component 3 can drive the discharge pipe 231 to swing up and down, and limit the swing amplitude. When the discharge pipe 231 is inclined downward below the middle of the swing component 3, the discharging mechanism 4 adjusts the opening size of the discharging port. When the discharge pipe 231 is above the middle of the swing component 3, the discharging port is completely closed at this time for the liquid material to flow back.

[0030] By setting up the inclined discharge mechanism 2 and the discharging mechanism 4, the inclination angle of the discharge pipe 231 is adjusted according to the viscosity of the liquid feed. At the same time, the inclination angle of the discharge pipe 231 drives the discharging mechanism 4 to adjust the size of the discharge port, thereby achieving more precise discharging control. For high-viscosity liquid feed, increasing the opening and adjusting the inclination angle can improve the discharging efficiency and avoid blockage; for low-viscosity liquid feed, reducing the opening and adjusting the angle can prevent splashing and waste, thereby achieving the effect of ensuring discharge uniformity and product quality.

[0031] Reference Figure 9 - Figure 11 The opening and closing assembly 44 includes an opening and closing clamping block 441 which is slidably connected between the discharge outer cover 43 and the discharge pipe 231. The opening of the opening and closing clamping block 441 is the same size as the discharge port. A plurality of return springs 443 are fixedly connected between one end of the opening and closing clamping block 441 and the inner wall of the discharge outer cover 43. A plurality of connecting ropes 442 are fixedly connected to one end of the opening and closing clamping block 441 away from the return springs 443. A scraper 444 is fixedly connected to one side of the opening of the opening and closing clamping block 441 close to the connecting ropes 442. A cross frame 41 is fixedly connected to the outer wall of the tank body 1. A rocking block 42 is rotatably connected to the inner wall of the cross frame 41. The ends of the plurality of connecting ropes 442 away from the closing clamping block 441 are all fixedly connected to the bottom of the rocking block 42.

[0032] Specifically, one end of the connecting rope 442 is fixed to the bottom of the swing block 42, and the swing block 42 swings in the cross frame 41 to adapt to the loosening and tightening of the connecting rope 442, and the other end of the connecting rope 442 is fixed to one end of the opening and closing clamping block 441, and the middle section of the connecting rope 442 slides inside the discharge cover 43, and the reset spring 443 connects the other end of the opening and closing clamping block 441 and the inner wall of the discharge cover 43. When the connecting rope 442 is tightened, the reset spring 443 is pulled open, and when the connecting rope 442 is loose, the reset spring 443 resets itself.

[0033] By setting the opening and closing component 44, when the viscosity of the slurry is high, the multiple connecting ropes 442 at the bottom of the rocking block 42 pull the opening and closing clamping block 441 in the discharge cover 43, so that the opening of the opening and closing clamping block 441 is aligned with the discharge port. At this time, the discharge port, the opening of the opening and closing clamping block 441 and the opening of the discharge cover 43 are connected, and are all at the maximum opening size, which is convenient for discharging slurry with higher viscosity. When the viscosity of the slurry is low, the connecting rope 442 will loosen a part of the opening and closing clamping block 441, so that the opening of the opening and closing clamping block 441 is offset from the discharge port under the reset of multiple reset springs 443. At this time, the discharge port can be adjusted to facilitate the discharge of slurry with lower viscosity.

[0034] Reference Figure 2 - Figure 4, one end of the discharge pipe 231 far away from the tank body 1 is fixedly connected with a servo motor 24, the output shaft of the servo motor 24 is sleeved with an extrusion screw 234, the extrusion screw 234 is arranged inside the discharge pipe 231, one end of the discharge pipe 231 close to the tank body 1 is fixedly connected with a ball valve cover 232, and a through hole 233 is opened on the inner wall of the ball valve cover 232.

[0035] Refer to Figure 2 - Figure 4 , the valve assembly 22 includes a one-way ball valve 221 rotatably connected to the inner wall of the ball valve cover 232, an outer wall of the one-way ball valve 221 is fixedly connected with a bearing 224, an outer wall of the bearing 224 is rotatably connected with an inner wall of the through hole 233, one end of the bearing 224 is fixedly connected with a micro motor 223, and a material passing hole 222 is opened on the inner wall of the one-way ball valve 221.

[0036] Specifically, the bearing 224 passes through the through hole 233 to connect the ball valve cover 232 and the one-way ball valve 221 together. When the discharge pipe 231 swings upward or downward, the one-way ball valve 221 can be driven to swing.

[0037] Through the arranged discharge assembly 23 and valve assembly 22, after the inclination angle and the opening size are adjusted, the micro motor 223 can be operated. The output shaft of the micro motor 223 drives the one-way ball valve 221 to rotate in the ball valve cover 232 through the bearing 224. At the same time, the degree of misalignment between the material passing hole 222 and the discharge port 212 can adjust the size of the discharge port 212. Then the servo motor 24 is operated. The output shaft of the servo motor 24 drives the extrusion screw 234 to rotate in the discharge pipe 231 to convey the liquid material. At the same time, the servo motor 24 can adjust the conveying speed.

[0038] Refer to Figure 2 - Figure 4 , the fixing assembly 21 includes a fixing shell 211 fixedly connected to the outer wall of the tank body 1. A limiting groove 213 is opened on the inner wall of the fixing shell 211. The inner wall of the limiting groove 213 is slidably connected with the outer wall of the bearing 224. A discharge port 212 is opened on the inner wall of the fixing shell 211. When the one-way ball valve 221 is in an open state, the discharge port 212 is in a communicating state with the tank body 1, the material passing hole 222, and the discharge pipe 231.

[0039] Specifically, the fixing shell 211 plays a role in supporting the valve. One side of the discharge port 212 close to the tank body 1 is a slope, which is convenient for the discharge and reflux of the liquid material. One side of the discharge port 212 far away from the tank body 1 can fit the swing of the discharge pipe 231, and the opening size of the limiting groove 213 also fits the swing of the bearing 224.

[0040] When the one-way ball valve 221 is in the open state through the set fixed component 21, the liquid material can enter the discharge pipe 231 through the discharge port 212 and the material passing hole 222, and the liquid material in the discharge pipe 231 can also flow back into the tank body 1.

[0041] Referring to Figure 5 - Figure 6 , the swing component 3 includes an arc-shaped frame 31 fixedly connected to the outer wall of the tank body 1. A swing groove 32 is formed in the inner wall of the arc-shaped frame 31. The inner wall of the swing groove 32 is slidably connected to the outer wall of the discharge pipe 231. Two symmetrically arranged guide grooves 38 are formed in the inner wall of the arc-shaped frame 31. Guide bars 35 are slidably connected to the inner walls of the two guide grooves 38. An arc-shaped rack 34 is connected between the two guide bars 35. The upper end of the arc-shaped rack 34 is fixedly connected to an arc-shaped support block 33. The arc-shaped support block 33 is arranged below the discharge pipe 231. The arc-shaped rack 34 is slidably connected inside the arc-shaped frame 31. A rotary cylinder 37 is arranged on one side of the arc-shaped frame 31. A driving gear 36 is sleeved on the output end of the rotary cylinder 37. The driving gear 36 meshes with the arc-shaped rack 34.

[0042] Through the set swing component 3, when the viscosity of the liquid material is relatively high, the rotary cylinder 37 is operated. The output end of the rotary cylinder 37 drives the arc-shaped rack 34 to slide in the arc-shaped frame 31 through the driving gear 36. The discharge pipe 231 is supported by the arc-shaped support block 33 to swing in the swing groove 32, and is limited by the guide bars 35 and the guide grooves 38. When the discharge pipe 231 is at the bottom of the swing groove 32, the inclination angle is the largest. When the viscosity of the liquid material is relatively low, similarly, the swing component 3 is operated to make the discharge pipe 231 in the lower position of the swing groove 32, not at the bottom, so that the inclination angle can be adjusted. After one discharge is completed, the rotary cylinder 37 is operated in the reverse direction to swing the discharge pipe 231 to the top of the swing groove 32 to provide an inclination angle for the backflow.

[0043] During use, the inclination angle of the discharge pipe 231 is adjusted according to the viscosity of the feed liquid. At the same time, the inclination angle of the discharge pipe 231 drives the movement of the opening and closing clamping block 441, so as to adjust the size of the discharge port. When the viscosity of the feed liquid is high, it is necessary to increase the inclination angle and the size of the opening. The swing component 3 is operated to adjust the inclination angle to the maximum, and at the same time, the opening of the opening and closing clamping block 441 is driven to align with the discharge port. At this time, the discharge port, the opening of the opening and closing clamping block 441 and the opening of the discharge cover 43 are connected, and are all at the maximum opening size, which is convenient for discharging feed liquid with high viscosity. When the viscosity of the feed liquid is low, it is necessary to reduce the inclination angle and the size of the opening. Similarly, the swing component 3 is operated to make the discharge pipe 231 below the swing groove 32, not to the bottom, so as to adjust the inclination angle. The inclination angle can be adjusted, and at the same time, the opening of the opening and closing clamping block 441 is misaligned with the discharge port. At this time, the discharge port can be adjusted to facilitate the discharge of liquid with low viscosity. After the inclination angle and the opening size are adjusted, the size of the discharge port 212 can be adjusted by running the valve assembly 22. At the same time, the servo motor 24 can drive the discharge assembly 23 to adjust the conveying speed. When one discharge is completed, the rotary cylinder 37 is reversed to make the discharge pipe 231 swing to the top of the swing groove 32. At the same time, the opening and closing clamping block 441 is also reset by the reset spring 443, and its opening is completely misaligned with the discharge port, so the discharge port is closed, and the scraper 444 will also scrape off the residual liquid at the discharge port during the movement to prevent the liquid from dripping and polluting the working environment.

[0044] Working principle of the present invention: During operation, the inclination angle of the discharge pipe 231 is adjusted according to the viscosity of the liquid material. At the same time, the inclination angle of the discharge pipe 231 drives the movement of the opening and closing clamping block 441 to adjust the size of the discharge port.

[0045] When the viscosity of the material liquid is high, it is necessary to increase the inclination angle and the opening size, and operate the rotating cylinder 37. The output end of the rotating cylinder 37 drives the arc rack 34 to slide in the arc frame 31 through the driving gear 36, and the discharge pipe 231 is supported by the arc support block 33 to swing in the swing groove 32, and is limited by the guide bar 35 and the guide groove 38. When the discharge pipe 231 is at the bottom of the swing groove 32, the inclination angle is the largest. At the same time, the multiple connecting ropes 442 at the bottom of the rocking block 42 pull the opening and closing clamp 441 in the discharge cover 43 to align the opening of the opening and closing clamp 441 with the discharge port. At this time, the discharge port, the opening of the opening and closing clamp 441 and the opening of the discharge cover 43 are connected, and are all at the maximum opening size, which is convenient for discharging material with higher viscosity.

[0046] When the viscosity of the liquid material is relatively low, it is necessary to reduce the tilt angle and the opening size. Similarly, operate the swing assembly 3 to make the discharge pipe 231 located below the swing slot 32, not at the bottom. The tilt angle can be adjusted. At the same time, the connecting rope 442 will loosen a part of the opening and closing clamp block 441, so that the opening of the opening and closing clamp block 441 is offset from the discharge port under the reset of multiple reset springs 443. At this time, the discharge port can be adjusted to facilitate the discharge of the liquid material with relatively low viscosity.

[0047] After the adjustment of the tilt angle and the opening size is completed, the micro motor 223 can be operated. The output shaft of the micro motor 223 drives the one-way ball valve 221 to rotate in the ball valve cover 232 through the bearing 224, so that the liquid material can enter the discharge pipe 231 through the discharge port 212 and the material passing hole 222. At the same time, the degree of misalignment between the material passing hole 222 and the discharge port 212 can adjust the size of the discharge port 212. Then operate the servo motor 24. The output shaft of the servo motor 24 drives the extrusion screw 234 to rotate in the discharge pipe 231 to convey the liquid material. At the same time, the servo motor 24 can adjust the conveying speed.

[0048] After one discharge is completed, operate the rotary cylinder 37 in the reverse direction to swing the discharge pipe 231 to the uppermost position of the swing slot 32. At the same time, the opening and closing clamp block 441 is also reset under the reset spring 443, and its opening is completely offset from the discharge port to close the discharge port. And the scraper 444 will also scrape the residual liquid material at the discharge port during the movement to avoid the liquid material dripping and polluting the working environment.

[0049] After the discharge port is closed, operate the servo motor 24 in the reverse direction to drain the liquid material in the discharge pipe 231 obliquely back into the tank body 1, and then close the one-way ball valve 221 to avoid the external air polluting the inside of the tank body 1.
