Description

Technical Field

[0001] This utility model relates to the field of flat wire drawing machines, and in particular to a flat wire drawing machine that can ensure uniform wire thickness in the product. Background Technology

[0002] A flat filament drawing machine is a piece of equipment used to process plastic materials. It is mainly used to process plastic raw materials into flat filaments. Its working principle is to make the plastic raw materials into the required flat filament products through processes such as heating, extrusion, stretching and cooling. In order to quickly cool the film, existing flat filament drawing machines usually directly pass the film into clean water after extrusion. However, during the long-term cooling process, the overall temperature of the clean water will rise due to heat. However, traditional flat filament drawing machines do not have a structure for rapid cooling of clean water, which makes it impossible to keep the clean water at a certain low temperature. This directly affects the cooling effect on the film, and consequently, it is impossible to guarantee the thickness uniformity of the filaments in the subsequent products, which easily increases the defect rate.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0024] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0025] A flat filament drawing machine that ensures uniform filament thickness in products includes a flat filament drawing machine body 1. An auxiliary water tank 2 for cooling the extruded film is placed on one side of the machine body 1. A controller is located on the right side of the front of the auxiliary water tank 2. The film outlet end of the machine body 1 extends into the auxiliary water tank 2. Vertical plates 4 are symmetrically fixed to the front and back of the right side of the top of the auxiliary water tank 2. Guide cylinders 3 for guiding the extruded film are rotatably installed on both sides of the bottom of the inner cavity of the auxiliary water tank 2 and on the top of the vertical plates 4, which are close to each other. A sealed box 5 is fixed to the bottom of the front of the auxiliary water tank 2. Both the auxiliary water tank 2 and the sealed box 5 are equipped with auxiliary components for circulating and cooling the purified water in the auxiliary water tank 2. The auxiliary components include a water pump 6 fixed to the left side of the bottom of the front of the auxiliary water tank 2 with its inlet end connected to the auxiliary water tank 2. A serpentine tube 7 is installed inside the sealed box 5, and the outlet end of the water pump 6 passes through the outlet pipe into the sealed box 5 and is connected to one end of the serpentine tube 7. The other end of the serpentine tube 7 is connected to a vertical pipe 8, and the top end of the vertical pipe 8 passes through the sealed box 5. Box 5 is connected to a U-shaped tube 10 with both ends inserted into the top of the auxiliary water tank 2. Multiple sets of spray pipes 11 extending into the auxiliary water tank 2 are connected sequentially to both sides of the bottom of the U-shaped tube 10 along the front-to-back direction. A cooler 12 is fixed to the sealed box 5. An air pump 13 with its inlet end connected to the outlet end of the cooler 12 is fixed to the front of the sealed box 5. The outlet end of the air pump 13 is connected to the right side of the bottom front of the sealed box 5. Heat-conducting baffles 14, which are interlocked and fixed to the serpentine tube 7, are fixed interlocked along the vertical direction inside the sealed box 5. One end of the heat-conducting partition 14, which is far apart from each other, extends to the outside of the sealing box 5. A reinforcing side frame 17 is fixed on the auxiliary water tank 2. A motor 18 is fixed on the reinforcing side frame 17 by a bracket. A crankshaft 21 is fixed on the output shaft of the motor 18. A pull plate 19 located inside the U-shaped tube 10 is slidably arranged on the auxiliary water tank 2. Multiple sets of stirring plates 20 extending into the auxiliary water tank 2 are fixed in sequence along the front-back direction at the bottom of the pull plate 19. An auxiliary groove 22 is opened on the pull plate 19 for the bottom end of the crankshaft 21 to be inserted.

[0026] Specifically, this invention, through the setting of auxiliary components, utilizes a water pump 6 to quickly transport heated purified water into the serpentine tube 7. The design of the air cooler 12 and air pump 13, along with the heat-conducting baffle 14, can quickly cool the purified water in the serpentine tube 7. Under the action of the venturi tube 9, it is quickly transported back to the auxiliary water tank 2. The design of the motor 18, crankshaft 21, auxiliary groove 22, pull plate 19, and stirring plate 20 can accelerate the fusion speed of the purified water in the auxiliary water tank 2 and the cooled purified water, thereby forming a rapid circulation cooling structure for the purified water. This allows the purified water in the auxiliary water tank 2 to continuously maintain a certain low temperature, which facilitates the rapid cooling of the extruded film, ensuring the uniformity of the thickness of the subsequent product filaments and greatly reducing the defect rate.

[0027] An exhaust pipe 15 is connected to the top left side of the sealed box 5 and to the heat-conducting partition 14. A ring-shaped heat dissipation plate 16 is symmetrically embedded on the left side of the auxiliary water tank 2. Two sets of blowpipes adapted to the ring-shaped heat dissipation plate 16 are symmetrically connected to the end of the exhaust pipe 15 away from the sealed box 5 in the front-back direction.

[0028] Specifically, the design of the annular heat sink 16 can quickly dissipate heat from the auxiliary water tank 2. Combined with the airflow impact of the exhaust pipe 15, it can accelerate the gas flow rate on the surface of the annular heat sink 16, thereby accelerating the heat dissipation speed on the surface of the annular heat sink 16. This allows it to better and faster absorb and conduct heat from the purified water in the auxiliary water tank 2, further accelerating the cooling speed of the purified water.

[0029] There is a gap between the right side of the upper heat-conducting partition 14 and the left side of the lower heat-conducting partition 14 and the side wall of the inner cavity of the sealing box 5.

[0030] Specifically, the spacing design allows the two sets of heat-conducting baffles 14 to form a serpentine flow channel structure within the sealed box 5, extending the contact time between the cold air and the serpentine tube 7, and enabling the cold air to fully contact the serpentine tube 7, thereby improving the cooling effect on the purified water inside the serpentine tube 7.

[0031] A Venturi tube 9 is installed on the vertical tube 8.

[0032] Specifically, the design of the Venturi tube 9 utilizes its characteristics to accelerate the purified water discharged through the vertical pipe 8, causing it to be sprayed out through the nozzle 11 at a faster speed. This impacts and agitates the purified water in the auxiliary water tank 2, accelerating the fusion speed and improving the cooling effect.

[0033] The auxiliary water tank 2 is symmetrically provided with anti-slip tracks along the front and back directions, and anti-slip seats with their tops fixed to the pull plate 19 are slidably installed in the anti-slip tracks.

[0034] Specifically, by utilizing the sliding connection between the anti-slip track and the anti-slip seat, the direction of movement of the pull plate 19 can be limited, thereby improving the stability of the pull plate 19 during movement and preventing deviation.

[0035] Each nozzle group 11 is equipped with an auxiliary one-way valve.

[0036] Specifically, the auxiliary one-way valve is designed to limit the drainage direction of the nozzle 11, preventing clean water in the auxiliary water tank 2 from flowing into the nozzle 11 and affecting its normal use.

[0037] The specific usage process is as follows: When the extruded film for preparing the product filament is extruded through the flat filament drawing machine body 1, it reaches a very high temperature. At this time, the purified water in the auxiliary water tank 2 continuously cools it down. However, after a period of time, the purified water will heat up. At this point, the user turns on the water pump 6, the air cooler 12, and the air pump 13 via the controller. The water pump 6 delivers the heated purified water in the auxiliary water tank 2 to the serpentine tube 7, while the air pump 13 delivers the cold air generated by the air cooler 12 to the sealed box 5. Two sets of staggered heat-conducting baffles 14 divide the sealed box 5 into a serpentine flow channel structure, extending the circulation time of the cold air in the sealed box 5, facilitating uniform cooling of the purified water in the serpentine tube 7. The heat-conducting baffles 14 can further absorb heat. The water is conducted to the outside environment, further accelerating the cooling process. The cooled purified water is then transported through the vertical pipe 8 to the U-shaped pipe 10, where it is accelerated by the Venturi tube 9. This allows the purified water to impact the auxiliary water tank 2 at a certain speed, agitating the water and accelerating the fusion process. Simultaneously, the user activates the motor 18 via a controller. The motor 18 drives the crankshaft 21 to rotate, and in conjunction with the auxiliary tank 22, it drives the pull plate 19 and the stirring plate 20 to move back and forth, further agitating the purified water in the auxiliary water tank 2 and accelerating the fusion process. This maintains the purified water in the auxiliary water tank 2 at a continuously low temperature, allowing for continuous and rapid cooling of the extruded membrane. To ensure the uniformity of the thickness of the filaments in subsequent product preparation, this invention utilizes auxiliary components, including a water pump 6, to rapidly transport heated purified water into the serpentine tube 7. The design of the air cooler 12 and air pump 13, along with the heat-conducting baffle 14, rapidly cools the purified water within the serpentine tube 7. Under the action of the venturi tube 9, the water is then quickly returned to the auxiliary water tank 2. Furthermore, the design of the motor 18, crankshaft 21, auxiliary tank 22, pull plate 19, and stirring plate 20 accelerates the fusion speed of the purified water in the auxiliary water tank 2 and the cooled purified water, thus forming a rapid circulating cooling structure for the purified water. This allows the purified water in the auxiliary water tank 2 to sustainably maintain a certain low temperature, facilitating rapid extrusion of the film. Cooling ensures the uniformity of the thickness of the filaments in subsequent product preparation, greatly reducing the defect rate. The design of the annular heat sink 16 can quickly dissipate heat from the auxiliary water tank 2. Combined with the airflow impact of the exhaust pipe 15, it can accelerate the gas flow rate on the surface of the annular heat sink 16, thereby accelerating the heat dissipation speed on the surface of the annular heat sink 16. This allows it to better and faster absorb and conduct heat from the purified water in the auxiliary water tank 2, further accelerating the cooling speed of the purified water. The spacing design allows the two sets of heat-conducting baffles 14 to form a serpentine flow channel structure within the sealed box 5, extending the contact time between the cold air and the serpentine tube 7, allowing the cold air to fully contact the serpentine tube 7, thereby improving the cooling effect on the purified water within the serpentine tube 7.The Venturi tube 9, utilizing its characteristics, accelerates the purified water discharged through the vertical pipe 8, causing it to be sprayed out of the nozzle 11 at a faster speed. This impacts and agitates the purified water in the auxiliary water tank 2, accelerating the fusion process and improving the cooling effect. The sliding connection between the anti-slip track and the anti-slip seat limits the movement direction of the pull plate 19, improving its stability and preventing deviation. The auxiliary one-way valve design limits the drainage direction of the nozzle 11, preventing purified water from the auxiliary water tank 2 from flowing into the nozzle 11 and affecting its normal operation.

[0038] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
