Description

Technical Field

[0001] This utility model relates to the field of fabric production technology, specifically a twisting device for polyester knitted fabric. Background Technology

[0002] Polyester knitted fabric is woven from multiple polyester threads. The polyester threads are made by twisting multiple individual fiber bundles. During the twisting process, one end of the fiber bundle is held and the other end is rotated to form a yarn bundle.

[0003] A search revealed a utility model patent with Chinese patent publication number CN217052525U, which discloses a twisting device for high-strength polyester-cotton composite knitted fabric. This device belongs to the field of high-strength polyester-cotton composite knitted fabric processing technology. It includes a base, a twisting box connected to the top of the base, and a dust collection box. A dust suction hood is connected to the side of the twisting box, and a dust suction pipe connects the dust suction hood to the dust collection box. A dust suction fan is connected to the inner wall of the dust suction pipe. An atomizing spray pipe is connected to the inner top wall of the dust collection box, and a filter screen is connected to the inner wall of the dust collection box.

[0004] The aforementioned device achieves the twisting of multi-strand fiber bundles by driving a twisting disc. However, when put into use, it is inevitable that the number of twists will be insufficient due to insufficient tension and friction, which will have a certain impact on the products produced subsequently, and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a twisting device for polyester knitted fabric to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polyester knitted fabric twisting device, comprising a protective box, an installation plate detachably mounted on the bottom inner wall of the protective box via bolts, a twisting assembly mounted on the top of the installation plate, the twisting assembly comprising an installation shaft coaxially fixed to the top outer wall of the installation plate, a toothed pulley rotatably connected to the outer circumference of the installation shaft via bearings, a plurality of equally spaced extension plates provided on the outer circumference of the toothed pulley, a gear rod rotatably connected to the top outer wall of each of the three extension plates, a toothed ring coaxially fixed to the top outer wall of the installation plate, the plurality of gear rods meshing with the toothed ring, and a concentrating ring coaxially fixed to the top outer wall of the toothed pulley.

[0007] As a further preferred embodiment of this technical solution, a support frame is fixedly connected to the top outer wall of each of the three gear rods. A horizontally arranged mounting rod is rotatably connected inside each of the three support frames via bearings, and the end of the mounting rod is cylindrical. A limiting plate is detachably connected to one side outer wall of each of the three support frames via bolts, and a sleeve adapted to the mounting rod is rotatably connected inside the limiting plate via bearings.

[0008] As a further preferred embodiment of this technical solution, the support frame is internally threaded with a vertically arranged lead screw, and a contact strip is rotatably connected to the top end of the lead screw via a bearing. Two vertically arranged limiting rods are fixedly connected to the bottom outer wall of the contact strip, and both limiting rods are slidably inserted into the support frame.

[0009] This system enables the fiber bundle to rotate actively, effectively avoiding insufficient twisting due to insufficient friction and tension. It also allows for stranding after twisting, improving processing efficiency. The bobbin is fitted onto the outside of the mounting rod, and then a limiting plate is fitted onto the end of the mounting rod, thus restricting the bobbin's position. The contact between the toothed pulley and the outer wall of the mounting rod is adjusted to prevent the bobbin from rotating arbitrarily. Combined with an external winding device, this ensures the fiber bundle tension, improving product quality. A knob drives the screw to rotate, and the contact strip, driven by the screw and the limiting rod, is pressed against the outer wall of the mounting rod. The fiber bundle tension can be controlled by adjusting the friction between the two. Then, a transmission device and belt drive the toothed pulley to rotate outside the mounting shaft. The toothed pulley, through an extension plate, drives multiple gear rods to revolve. These gear rods, through meshing toothed rings, rotate simultaneously, thus initiating twisting. The strands are then concentrated and stranded from the concentrator at the top of the toothed pulley.

[0010] As a further preferred embodiment of this technical solution, the protective box is rotatably connected to a door via a hinge, and the door can close the opening of the protective box.

[0011] As a further preferred embodiment of this technical solution, multiple nozzles are provided on both sides of the outer wall of the protective box, one end of the outer wall, and one end of the outer wall of the box door, and the openings of the multiple nozzles are all inclined upwards. A collection pipe is fixedly connected to the top outer wall of the protective box, and a connecting pipe is fixedly inserted into the top outer wall of the collection pipe. Two diversion pipes are provided at the bottom end of the connecting pipe. A dust collector is fixedly connected to one end of the outer wall of the protective box. The dust collector has two vertically arranged chambers inside, and the two diversion pipes are fixedly inserted into the top of the dust collector, and the two diversion pipes are respectively connected to the two chambers.

[0012] As a further preferred embodiment of this technical solution, each of the two chambers inside the dust collector is provided with a horizontally arranged shelf, and each of the two shelves contains a filter cartridge. A fan is fixedly installed at the bottom of each dust collector, and the two fans are respectively connected to the two chambers.

[0013] Start a fan at the bottom of the dust collector, which draws air out of one of the chambers. The space between the protective box and the door is drawn out by the connecting pipe and the diversion pipe. Then, the outside air enters the protective box through multiple nozzles. Multiple upward airflows blow the lint upwards, preventing it from falling onto the toothed ring. The lint carrying the airflow then enters the collection pipe, and then enters one of the chambers of the dust collector through the connecting pipe and one of the diversion pipes. After being filtered by the filter cartridge, it flows outwards. After a period of use, start another fan, close the valve of the original diversion pipe, and open the valve of the other diversion pipe. The lint will then be filtered through another channel. At this point, the filter cartridge full of lint can be processed.

[0014] As a further preferred embodiment of this technical solution, the top wall of the protective box is sloped, and the connection point between the connecting pipe and the protective box is located at the highest point of the slope.

[0015] This utility model provides a twisting device for polyester knitted fabric, which has the following beneficial effects:

[0016] (1) By setting a twisting component, this utility model enables the fiber bundle to rotate actively, effectively avoiding the problem of insufficient twisting due to insufficient friction and tension. It can also be stranded after twisting, which is beneficial to improving processing efficiency. The bobbin is placed outside the mounting rod, and then the limiting plate is placed at the end of the mounting rod, so the position of the bobbin is restricted. Then the contact degree between the toothed pulley and the outer wall of the mounting rod is adjusted so that the bobbin will not rotate randomly. With the help of the external winding device, the tension of the fiber bundle can be guaranteed, which is beneficial to improving product quality. The screw is rotated by the knob, and the contact strip is squeezed on the outer wall of the mounting rod under the drive of the screw and the cooperation of the limiting rod. The tension of the fiber bundle can be controlled by adjusting the friction between the two. Then the toothed pulley is rotated outside the mounting shaft by the transmission device and the belt. The toothed pulley drives multiple gear rods to revolve through the extension plate. The gear rods rotate on their own axis while revolving through the toothed rings that mesh with them. Twisting can then begin. Then the strands are concentrated from the concentrating frame at the top of the toothed pulley.

[0017] (2) This utility model is equipped with nozzles, collection pipes, connecting pipes, diversion pipes, dust collection boxes, storage plates and filter cartridges. When a fan at the bottom of the dust collection box is started, it draws the air out of one of the chambers in the dust collection box. The space formed by the protective box and the box door is drawn out by the connecting pipe and the diversion pipe. Then the external air will enter the protective box through multiple nozzles. Multiple inclined upward airflows can blow the fluff upward and also prevent the fluff from falling onto the toothed ring. Then the fluff carrying the airflow enters the collection pipe, and then enters one of the chambers of the dust collection box through the connecting pipe and one of the diversion pipes. After being filtered by the filter cartridge, it will flow outward. After a period of use, another fan is started and the valve of the original diversion pipe is closed and the valve of the other diversion pipe is opened. The fluff will be filtered through another channel. At this time, the filter cartridge full of fluff can be processed. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, a polyester knitted fabric twisting device includes a protective box 1. An installation plate 3 is installed on the bottom inner wall of the protective box 1 by bolts. A twisting component 11 is installed on the top of the installation plate 3. The twisting component 11 includes an installation shaft 111 coaxially fixed to the top outer wall of the installation plate 3. A toothed pulley 112 is rotatably connected to the outer circumference of the installation shaft 111 via a bearing. Multiple equally spaced extension plates 113 are provided on the outer circumference of the toothed pulley 112. A gear rod 115 is rotatably connected to the top outer wall of each of the three extension plates 113. A toothed ring 114 is coaxially fixed to the top outer wall of the installation plate 3. Multiple gear rods 115 mesh with the toothed ring 114. A concentrating ring is coaxially fixed to the top outer wall of the toothed pulley 112.

[0025] Each of the three gear rods 115 has a support frame 116 fixedly connected to its top outer wall. Each of the three support frames 116 has a horizontally mounted rod 117 rotatably connected to it via bearings. The end of the mounted rod 117 is cylindrical. Each of the three support frames 116 has a limiting plate 118 detachably connected to its side outer wall via bolts. The limiting plate 118 has a ferrule that is compatible with the mounted rod 117 rotatably connected to it via bearings.

[0026] The toothed pulley 112 is driven to rotate outside the mounting shaft 111 by the transmission device and belt. The toothed pulley 112 drives multiple gear rods 115 to revolve through the extension plate 113. The gear rods 115 rotate on their own axis while revolving through the toothed rings 114 that mesh with them, thus starting the twisting process. Then, the strands are gathered together from the concentrator on the top of the toothed pulley 112.

[0027] The support frame 116 is internally threaded with a vertically arranged lead screw 119. The top end of the lead screw 119 is rotatably connected to a friction strip 121 (the upper half of which is made of rubber material) via a bearing. Two vertically arranged limiting rods 120 are fixedly connected to the bottom outer wall of the friction strip 121. Both limiting rods 120 are slidably inserted into the support frame 116 to fit the bobbin onto the outside of the mounting rod 117. Then, a limiting plate 118 is fitted onto the end of the mounting rod 117, thus restricting the position of the bobbin. The contact degree between the toothed pulley 112 and the outer wall of the mounting rod 117 is then adjusted to prevent the bobbin from rotating arbitrarily. Combined with the external winding device, the tension of the fiber bundle can be guaranteed, which is beneficial to improving product quality. By rotating the lead screw 119 with a knob, the contact strip 121, driven by the lead screw 119 and in cooperation with the limiting rods 120, will be pressed against the outer wall of the mounting rod 117. The tension of the fiber bundle can be controlled by adjusting the friction between the two.

[0028] like Figure 1 As shown, the protective box 1 is connected to a door 2 by a hinge, which can close the opening of the protective box 1.

[0029] Multiple nozzles 4 are provided on both sides of the outer wall of the protective box 1, one end of the outer wall, and one end of the outer wall of the door 2. The openings of the multiple nozzles 4 are all inclined upwards. A collection pipe 5 is fixedly connected to the top outer wall of the protective box 1. A connecting pipe 6 is fixedly inserted into the top outer wall of the collection pipe 5. Two diversion pipes 7 are provided at one end of the bottom of the connecting pipe 6. A dust collector 8 is fixedly connected to one end of the outer wall of the protective box 1. The dust collector 8 has two vertically arranged chambers inside. The two diversion pipes 7 are fixedly inserted into the top of the dust collector 8 and are connected to the two chambers respectively.

[0030] The dust collector 8 has two chambers, each with a horizontally arranged shelf 9. Each shelf 9 contains a filter cartridge 10. A fan is fixedly installed at the bottom of the dust collector 8, and the two fans are connected to the two chambers respectively.

[0031] Start a fan at the bottom of the dust collector 8 to draw air out of one of the chambers. The space formed by the protective box 1 and the door 2 is drawn out by the connecting pipe 6 and the diversion pipe 7. Then, the outside air enters the protective box 1 through multiple nozzles 4. Multiple upward airflows blow the lint upwards, preventing the lint from falling onto the toothed ring 114. The lint carrying the airflow then enters the collection pipe 5, and then enters one of the chambers of the dust collector 8 through the connecting pipe 6 and one of the diversion pipes 7. After being filtered by the filter cartridge 10, it flows outwards. After a period of use, start another fan and close the valve of the original diversion pipe 7 and open the valve of the other diversion pipe 7. The lint will then be filtered through another channel. At this time, the filter cartridge 10, which is full of lint, can be processed, ensuring uninterrupted operation and improving work efficiency.

[0032] like Figure 1 As shown, the top wall of the protective box 1 is set on an sloping surface, and the connection point between the connecting pipe 6 and the protective box 1 is located at the highest point of the sloping surface. When the airflow comes into contact with the top wall of the protective box 1, it will slide along the slope, effectively preventing the protective box 1 from trapping lint.

[0033] This utility model provides a twisting device for polyester knitted fabric, the specific working principle of which is as follows:

[0034] When the device is in operation, the bobbin is fitted over the mounting rod 117, and then the limiting plate 118 is fitted over the end of the mounting rod 117, thus restricting the position of the bobbin. The contact degree between the toothed pulley 112 and the outer wall of the mounting rod 117 is then adjusted to prevent the bobbin from rotating arbitrarily. Combined with the external winding device, this ensures the tension of the fiber bundle, which is beneficial for improving product quality. By rotating the screw 119 with a knob, the contact bar 121, driven by the screw 119 and in cooperation with the limiting rod 120, is pressed against the outer wall of the mounting rod 117. The tension of the fiber bundle can be controlled by adjusting the friction between the two. Then, the toothed pulley 112 is driven to rotate outside the mounting shaft 111 via a transmission device and belt. The toothed pulley 112 drives multiple gear rods 115 to revolve via an extension plate 113. The gear rods 115 rotate on their own axis while revolving, through the meshing toothed rings 114, thus initiating twisting. The air is then gathered and stranded from the central rack at the top of the toothed pulley 112. At the same time, a fan at the bottom of the dust collector 8 is started, which draws the air out of one of the chambers in the dust collector 8. The space formed by the protective box 1 and the box door 2 is drawn out by the connecting pipe 6 and the diversion pipe 7. Then, the outside air enters the protective box 1 through multiple nozzles 4. Multiple upward airflows can blow the lint upward and also prevent the lint from falling onto the toothed ring 114. Then, the lint carrying the airflow enters the collection pipe 5, and then enters one of the chambers in the dust collector 8 through the connecting pipe 6 and one of the diversion pipes 7. After being filtered by the filter cartridge 10, it flows outward. After a period of use, another fan is started, and the valve of the original diversion pipe 7 is closed and the valve of the other diversion pipe 7 is opened. The lint will then be filtered through another channel. At this time, the filter cartridge 10 full of lint can be processed, which can ensure continuous operation and improve work efficiency.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
