Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile setting technology, and in particular to a pneumatic edge blowing device for a tenter frame. Background Technology
[0002] Tentator machines are a very important textile finishing equipment in printing and dyeing plants. They are mainly used for drying and stretching knitted and woven fabrics. They utilize the plasticity of fabric fibers to slowly stretch the width of the fabric to a specified size within a certain range.
[0003] The stenter is equipped with an infrared selvage tracking device in the needle entry area to ensure that the fabric selvage falls accurately onto the needle plate of the stenter. Because the selvage of plush fabrics often has messy, disordered pile, it can affect the detection of the infrared selvage tracking device, leading to unstable needle entry, inconsistent needle distance, and selvage slippage, severely impacting the stable production of the stenter. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a pneumatic edge blowing device for a tenter frame that is reasonably designed and ensures flat fabric edges, in order to address the shortcomings of the existing technology.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A pneumatic edge-blowing device for a tenter frame includes edge tracking mechanisms on both sides of the fabric. The edge tracking mechanisms are mounted on a track assembly on the fabric feeding side of the upper needle assembly. The edge tracking mechanisms include photoelectric sensors for tracking the edge and a four-finger edge peeler for flattening the fabric edge, both fixed to the track assembly. The device is characterized by an edge-blowing mechanism for finishing the fabric edge, which includes a hollow air inlet seat with a ventilation chamber inside. An air outlet is located on one side of the ventilation chamber, and an air pipe is connected to the outlet via an air pipe connector to blow air towards the fabric edge. An air inlet is located at the top of the ventilation chamber, and a throttle valve is installed at the air inlet, connected to an air inlet pipe.
[0007] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the air inlet seat is a magnetic seat, and a magnet that attracts the magnetic seat is provided on the track assembly. There is no need to set a special mounting hole, which makes installation and positioning convenient and facilitates maintenance.
[0008] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the air blowing pipe is an adjustable hose, which can conveniently adjust the airflow direction of the air blowing pipe according to process needs. After the originally messy plush fabric edge is tidied by the air blowing of this device, the fabric edge is flat and detected by the infrared fabric edge tracking device photoelectric eye. The stitches on the fabric edge are consistent, and the equipment can produce stably.
[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the air outlet of the air blowing pipe is flat and the flat air outlet is set parallel to the edge of the fabric, thereby increasing the length of the blowing edge and improving the blowing efficiency.
[0010] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the height of the flat air inlet is equal to the height of the fabric edge, ensuring the edge blowing effect.
[0011] Compared with existing technologies, this invention uses an air-blowing pipe with a throttling valve at the fabric edge to blow away the lint, ensuring consistent needlework and preventing messy lint from affecting the infrared fabric edge tracking device's photoelectric sensor detection. The hollow air inlet seat facilitates air intake and installation; the magnetic seat eliminates the need for dedicated mounting holes, simplifying maintenance and repair. The pneumatic edge-blowing device for the tenter frame described in this invention is simple in principle, rationally structured, highly efficient in cooking, and produces better cooking results.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.
[0018] Reference Figure 1-3 A pneumatic edge-blowing device for a tenter frame includes edge tracking mechanisms on both sides of a fabric 5. The edge tracking mechanisms are mounted on a track assembly 8 on the fabric feeding side of an upper needle assembly 9. The edge tracking mechanisms include photoelectric sensors 7 located above the fabric edge for tracking the edge and a four-finger edge peeler 6 for flattening the fabric edge. Both the four-finger edge peeler 6 and the photoelectric sensors 7 are fixed to the track assembly 8 by threaded connections. An edge-blowing mechanism for straightening the fabric edge is installed on the track assembly 8. The edge-blowing mechanism includes a hollow air inlet seat 3 with a ventilation chamber inside. An air outlet is located on one side of the ventilation chamber. An air blowing pipe 4 is connected to the air outlet via an air pipe connector to blow air towards the fabric edge. An air inlet is located at the top of the ventilation chamber, and a throttle valve 2 is installed at the air inlet. An air inlet pipe 1 is connected to the throttle valve 2.
[0019] The air inlet seat 3 is a magnetic seat, and the track assembly 8 is provided with a magnet that attracts the magnetic seat.
[0020] The air blowing pipe 4 is an adjustable hose. The air blowing port of the air blowing pipe 4 is flat and parallel to the edge of the fabric. The height of the flat air blowing port is equal to the height of the edge of the fabric.
[0021] The pneumatic edge-blowing device of the tenter frame described in this utility model works as follows: Before the fabric 5 passes through the infrared edge tracking photoelectric eye 7, the airflow from the air blowing pipe 4 smooths the pile on the edge of the fabric 5, ensuring a smooth edge when it passes through the infrared edge tracking photoelectric eye 7. After the fabric 5 passes through the four-finger edge-spreading device 6, it finally enters the needle assembly 9 for smooth needle insertion. The fabric 5, after being smoothed by the air blowing pipe 4, has a neat needle insertion on the edge, preventing situations where the needle insertion distance is too large, resulting in wasted fabric, and also preventing edge shedding due to a small needle insertion distance.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
