Description

Technical Field

[0001] The utility model belongs to the technical field of plastic wire drawing machines, and particularly relates to a film discharging mechanism of a plastic extrusion flat film wire drawing machine. Background Technique

[0002] Plastic wire drawing machines use polypropylene and high-density ethylene as raw materials. After heating, extrusion, wire splitting, and stretching, flat filaments are formed and wound up for circular knitting machines to weave. Among them, plastic flat die wire drawing machines have two billet wire heating structures, namely hot air stretching air boxes or electric heating ovens, providing more choices and a wide range of applications. They can be used for the forming and processing of flat filaments of products such as polypropylene, high-density polyethylene, and linear low-density polyethylene. However, there are still the following drawbacks in actual use:

[0003] 1. The utility model with the publication number CN202139342U discloses a plastic flat film wire drawing machine. The extrusion device includes a frame, a conveying pipe, and a screw propeller. The conveying pipe is arranged on the outer periphery of the screw propeller, and the conveying pipe and the screw propeller are fixedly connected to the frame. The end of the extrusion device is connected to a cooling water tank, and the cooling water tank is connected to a wire drawing device. A wire drawing roller is arranged on the wire drawing device, and a tool rest is arranged on the wire drawing roller. A plurality of cutting knives are arranged at equal angles on the circumference of the tool rest. After the plastic wire is drawn out by the wire drawing device of the wire drawing machine, the tension on the plastic wire is relatively large. If the plastic wire is directly wound by the winding device, it is easy to break during the winding process, reducing the processing efficiency.

[0004] 2. After the plastic wire is drawn out by the wire drawing device of the wire drawing machine, the plastic wire may break due to external factors. When the plastic wire breaks, the staff can only control the winding device to stop and wind one end of the drawn plastic wire around the surface of the winding roller again. The operation is time-consuming and laborious, and it is easy to cause the subsequent produced plastic wire to accumulate. Content of the Utility Model

[0005] The purpose of the utility model is to provide a film discharging mechanism of a plastic extrusion flat film wire drawing machine. Through the film discharging support frame and the winding roller, the problem that after the plastic wire is drawn out by the wire drawing device of the plastic wire drawing machine, due to the relatively large tension on the plastic wire, direct winding is easy to break, and when the plastic wire breaks accidentally, it is necessary to manually wind the plastic wire around the surface of the winding roller again, reducing the processing efficiency is solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a film outlet mechanism of a plastic extrusion flat film drawing machine, which comprises a film outlet support frame and a winding roller. A net-shaped ventilation conveyor belt is rotationally clamped inside the film outlet support frame. A first fan and a second fan are respectively clamped at two ends inside the film outlet support frame. One end of the top of the film outlet support frame is suspended with a winding roller. A third fan is arranged on one side of the outer peripheral surface of the winding roller. A plurality of limiting rods are arranged on the other side of the outer peripheral surface of the winding roller;

[0008] The first fan can drive air to flow downward. Under the action of the air flow, the plastic filaments drawn by the drawing machine can adhere to the surface of the net-shaped ventilation conveyor belt, reducing the tension on the plastic filaments after forming and lowering the probability of plastic filament breakage. The rotation of the net-shaped ventilation conveyor belt can drive the movement of the plastic filaments, enabling the plastic filaments to move to the bottom of the winding roller, improving the automation degree of the film outlet mechanism. When the plastic filaments move to the bottom of the winding roller through the net-shaped ventilation conveyor belt, the second fan drives air to flow upward, causing the plastic filaments to move upward under the action of the air flow and adhere to the bottom of the winding roller. The rotation of the winding roller drives the movement of the plastic filaments. The third fan drives the air flow to blow onto the surface of the winding roller to prevent the plastic filaments from falling off when rotating with the winding roller. When the plastic filaments move to the other end of the winding roller, the limiting rods can limit the plastic filaments to prevent the plastic filaments from loosening and moving upward with the air flow, enabling the plastic filaments to be wound around the surface of the winding roller without manual winding, reducing the labor intensity of the staff. And when the plastic filaments are accidentally broken, the newly produced plastic filaments can still be automatically sorted and wound through the film outlet mechanism, improving the convenience of using the film outlet mechanism.

[0009] Furthermore, rotating rollers are rotatably connected to two ends inside the film outlet support frame. A rotating motor is fixed on one side of the film outlet support frame. The output shaft of the rotating motor penetrates through the film outlet support frame and is in transmission connection with the end of the rotating roller. The net-shaped ventilation conveyor belt is attached to the outer peripheral surface of the rotating roller;

[0010] The rotating motor can drive the rotating roller to rotate, and further drive the net-shaped ventilation conveyor belt to rotate, enabling the plastic filaments attached to the surface of the net-shaped ventilation conveyor belt to move with the rotation of the net-shaped ventilation conveyor belt, sorting and winding the processed plastic filaments.

[0011] Furthermore, a plurality of limiting plates are welded and fixed inside the film outlet support frame. The plurality of limiting plates are attached to the inside of the net-shaped ventilation conveyor belt. The first fan and the second fan are clamped between the plurality of limiting plates. The second fan is located at the bottom of the winding roller;

[0012] After the plastic filaments processed by the wire drawing machine move to the upper side of the film outlet support frame, the first fan can drive the air to flow downward, so that the plastic filaments can adhere to the surface of the mesh ventilation conveyor belt under the action of the air flow. The film outlet support frame sorts and moves the plastic filaments to prevent the plastic filaments from being directly wound by the winding device after forming. The plastic filaments are easily broken when they are under great tension during movement, ensuring the processing efficiency of the plastic filaments.

[0013] Further, one end of the top of the film outlet support frame is clamped with a slide rail, and a plurality of first guide plates and second guide plates are slidably clamped on one side of the slide rail. The first guide plates and the second guide plates are attached to the top of the mesh ventilation conveyor belt. The first guide plates and the second guide plates are located between the slide rail and the winding roller, and the first fan is located at the bottom of the first guide plates and the second guide plates;

[0014] The staff can adjust the distance between the first guide plate and the second guide plate according to the width of the plastic filaments, and guide the plastic filaments through the first guide plate and the second guide plate to ensure the accuracy of the winding position of the plastic filaments.

[0015] Further, one end of the winding roller is inserted through and connected to a winding support frame, a winding motor is fixed on the other side of the winding support frame, the output shaft of the winding motor penetrates through the winding support frame and is in transmission connection with the end of the winding roller, and a lifting cylinder is slidably clamped at the bottom of the winding support frame. The lifting cylinder is inserted through and clamped at the top of one side of the film outlet support frame;

[0016] By driving the air to flow upward through the second fan, the plastic filaments can adhere to the bottom of the winding roller. By driving the rotation of the winding roller through the winding motor, the plastic filaments attached to the bottom of the winding roller are further driven to rotate and wind. By driving the air flow to blow to the surface of the winding roller through the third fan, it can prevent the plastic filaments from falling off when rotating with the winding roller. When the plastic filaments move to the other end of the winding roller, the plastic filaments can be limited by the limiting rod to prevent the plastic filaments from loosening due to moving upward with the air flow, so that the plastic filaments are wound around the surface of the winding roller, and manual winding is not required, reducing the labor intensity of the staff. And when the plastic filaments are accidentally broken, the newly produced plastic filaments can still be automatically sorted and wound by the film outlet mechanism, improving the convenience of using the film outlet mechanism.

[0017] Further, a first telescopic cylinder is slidably clamped on one side of the third fan, and a second telescopic cylinder is slidably clamped at one end of each limiting rod. The first telescopic cylinder and the plurality of second telescopic cylinders are all inserted through and clamped on the outer peripheral surface of the winding support frame. The third fan is located on the other side of the winding roller relative to the slide rail;

[0018] When the plastic filaments wound around the surface of the winding roller continuously increase over time, control the lifting cylinder to drive the winding roller to move upward, and control the first telescopic cylinder and the second telescopic cylinder to drive the third blower and the limiting rod to move away from the winding roller, ensuring that the winding roller can wind a large amount of plastic filaments and improving the convenience of using the film outlet mechanism.

[0019] The utility model has the following beneficial effects:

[0020] 1. By setting up the film outlet support frame in the utility model, when the plastic filaments are pulled out by the wire drawing device of the wire drawing machine, the tension on the plastic filaments is relatively large. If the plastic filaments are directly wound by the winding device, they are likely to break during the winding process, reducing the processing efficiency. When the plastic filaments processed by the wire drawing device of the wire drawing machine are discharged from the film, when the plastic filaments move to the upper side of the film outlet support frame, the first blower drives the air to flow downward, making the plastic filaments adhere to the surface of the mesh ventilation conveyor belt, and the rotation of the mesh ventilation conveyor belt drives the movement of the plastic filaments, so that the plastic filaments move to the bottom of the winding roller for winding. By controlling the rotation speed of the winding roller to be slightly lower than the processing speed of the wire drawing machine, after the plastic filaments are formed, the external force on them is small, and they can shrink slightly, avoiding directly winding the plastic filaments through the winding device after they are formed. When the plastic filaments move, the large pulling force on them is likely to cause breakage, ensuring the processing efficiency of the plastic filaments.

[0021] 2. By setting up the film outlet support frame and the winding roller in the utility model, when the plastic filaments are pulled out by the wire drawing device of the wire drawing machine, the plastic filaments may break due to external factors. When the plastic filaments break, the staff can only control the winding device to stop and wind one end of the pulled-out plastic filaments around the surface of the winding roller again, which is time-consuming and laborious, and is likely to cause the subsequent produced plastic filaments to pile up. When the plastic filaments move to the bottom of the winding roller, the second blower drives the air to flow upward, making the plastic filaments adhere to the bottom of the winding roller. The rotation of the winding roller drives the plastic filaments adhering to the bottom of the winding roller for winding. The third blower drives the air flow to blow to the surface of the winding roller to prevent the plastic filaments from falling off when rotating with the winding roller. When the plastic filaments move to the other end of the winding roller, the limiting rod can limit the plastic filaments to prevent the plastic filaments from moving upward with the air flow and loosening, so that the plastic filaments are wound around the surface of the winding roller without manual winding, reducing the labor intensity of the staff. And when the plastic filaments break accidentally, the newly produced plastic filaments can still be automatically sorted and wound through the film outlet mechanism, improving the convenience of using the film outlet mechanism.

A third blower 201 is arranged on one side of the outer peripheral surface of the winding roller 2, and a plurality of limiting rods 202 are arranged on the other side of the outer peripheral surface of the winding roller 2;

[0030] When the plastic filaments processed by the wire drawing device of the drawing machine are discharged from the film, the rotation speed of the winding roller 2 is controlled to be slightly lower than the processing speed of the plastic filaments by the wire drawing device. When the plastic filaments move to the upper side of the film outlet support frame 1, the first blower 107 drives the air to flow downward, so that the plastic filaments are attached to the surface of the mesh ventilation conveyor belt 101 under the action of the air flow, and the movement of the plastic filaments is driven by the rotation of the mesh ventilation conveyor belt 101, so that the plastic filaments move to the bottom of the winding roller 2. When the plastic filaments move to the bottom of the winding roller 2 through the mesh ventilation conveyor belt 101, the second blower 108 drives the air to flow upward, so that the plastic filaments move upward under the action of the air flow and are attached to the bottom of the winding roller 2. The rotation of the winding roller 2 drives the movement of the plastic filaments. The third blower 201 drives the air flow to blow to the surface of the winding roller 2 to prevent the plastic filaments from falling off when rotating with the winding roller 2. When the plastic filaments move to the other end of the winding roller 2, the plastic filaments are limited by the limiting rods 202 to prevent the plastic filaments from loosening due to moving upward with the air flow, so that the plastic filaments are wound around the surface of the winding roller 2.

[0031] Among them, as Figures 1-3As shown, at both ends inside the film outlet support frame 1, there are rotatably connected rotating rollers 106. On one side of the film outlet support frame 1, a rotating motor 103 is fixed. The output shaft of the rotating motor 103 penetrates through the film outlet support frame 1 and is in transmission connection with the end of the rotating roller 106. The mesh ventilation conveyor belt 101 is attached to the outer peripheral surface of the rotating roller 106. Inside the film outlet support frame 1, a plurality of limiting plates 109 are welded and fixed. The plurality of limiting plates 109 are attached to the inside of the mesh ventilation conveyor belt 101. The first blower 107 and the second blower 108 are clamped between the plurality of limiting plates 109. The second blower 108 is located at the bottom of the winding roller 2. At one end of the top of the film outlet support frame 1, a slide rail 102 is clamped. On one side of the slide rail 102, a plurality of groups of first guide plates 104 and second guide plates 105 are slidably clamped. The first guide plates 104 and the second guide plates 105 are attached to the top of the mesh ventilation conveyor belt 101. The first guide plates 104 and the second guide plates 105 are located between the slide rail 102 and the winding roller 2. The first blower 107 is located at the bottom of the first guide plates 104 and the second guide plates 105;

[0032] When the plastic filaments processed by the wire drawing device of the wire drawing machine are discharged from the film, according to the width of the plastic filaments, the distance between the first guide plate 104 and the second guide plate 105 is adjusted. When the plastic filaments move to the upper side of the film outlet support frame 1, the first blower 107 drives the air to flow downward, so that the plastic filaments are attached to the surface of the mesh ventilation conveyor belt 101 under the action of the air flow. The rotating motor 103 drives the rotating roller 106 to rotate, further driving the mesh ventilation conveyor belt 101 to rotate, so that the plastic filaments attached to the surface of the mesh ventilation conveyor belt 101 move with the rotation of the mesh ventilation conveyor belt 101, and the plastic filaments are guided by the first guide plate 104 and the second guide plate 105.

[0033] Among them, as Figure 1 、 4 shown, one end of the winding roller 2 is inserted through and connected with a winding support frame 203. On the other side of the winding support frame 203, a winding motor 204 is fixed. The output shaft of the winding motor 204 penetrates through the winding support frame 203 and is in transmission connection with the end of the winding roller 2.

One end of each limiting rod 202 is slidably clamped with a second telescopic cylinder 207. The first telescopic cylinder 205 and the plurality of second telescopic cylinders 207 all penetrate and are clamped on the outer peripheral surface of the winding support frame 203. The third blower 201 is located on the other side of the winding roller 2 relative to the slide rail 102;

[0034] When the plastic filaments move to the bottom of the winding roller 2 through the mesh ventilation conveyor belt 101, the second fan 108 drives the air to flow upward, causing the plastic filaments to move upward under the action of the air flow and adhere to the bottom of the winding roller 2. The rotation of the winding roller 2 is driven by the winding motor 204, further driving the plastic filaments adhering to the bottom of the winding roller 2 to rotate and wind. When the plastic filaments move between the third fan 201 and the winding roller 2, the third fan 201 drives the air flow to blow onto the surface of the winding roller 2, causing the plastic filaments to adhere to the surface of the winding roller 2 and continue to move, preventing the plastic filaments from detaching from the surface of the winding roller 2 under the action of gravity. When the plastic filaments move to the other end of the winding roller 2, the plastic filaments are limited by the limiting rod 202, preventing the plastic filaments from loosening as they move upward with the air flow, and causing the plastic filaments to wind around the surface of the winding roller 2. When the plastic filaments wound on the surface of the winding roller 2 continuously increase over time, the lifting cylinder 206 is controlled to drive the winding roller 2 to move upward, and the first telescopic cylinder 205 and the second telescopic cylinder 207 are controlled to drive the third fan 201 and the limiting rod 202 to move away from the winding roller 2, ensuring that the winding roller 2 can wind a large amount of plastic filaments.

[0035] The specific working principle of the present utility model is as follows: When the plastic filaments processed by the wire drawing device of the wire drawing machine come out of the film, the distance between the first guide plate 104 and the second guide plate 105 is adjusted according to the width of the plastic filaments. When the plastic filaments move to the upper side of the film outlet support frame 1, the first fan 107 drives the air to flow downward, causing the plastic filaments to adhere to the surface of the mesh ventilation conveyor belt 101 under the action of the air flow. The rotation motor 103 drives the mesh ventilation conveyor belt 101 to rotate, causing the plastic filaments adhering to the surface of the mesh ventilation conveyor belt 101 to move with the rotation of the mesh ventilation conveyor belt 101, and guiding the plastic filaments through the first guide plate 104 and the second guide plate 105. When the plastic filaments move to the bottom of the winding roller 2, the second fan 108 drives the air to flow upward, causing the plastic filaments to move upward under the action of the air flow and adhere to the bottom of the winding roller 2. The rotation of the winding roller 2 is driven by the winding motor 204, further driving the plastic filaments adhering to the bottom of the winding roller 2 to rotate and wind. When the plastic filaments move between the third fan 201 and the winding roller 2, the third fan 201 drives the air flow to blow onto the surface of the winding roller 2, causing the plastic filaments to adhere to the surface of the winding roller 2 and continue to move, preventing the plastic filaments from detaching from the surface of the winding roller 2 under the action of gravity.
