Description

Technical field:

[0001] The utility model relates to the technical field of textile machinery and equipment, and more specifically to a traction device for polyester yarn production. Background technology:

[0002] Polyester is an important variety of synthetic fiber and is the trade name of polyester fiber in my country. It is a fiber made from polyethylene terephthalate (PET), a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or ester exchange and polycondensation reaction, and then spun and post-processed.

[0003] In the production process of polyester yarn, the polyester yarn needs to be pulled and tensioned. However, the feeding height of the existing traction device needs to correspond to its feeding equipment, and the discharging position of the traction device needs to correspond to the subsequent material receiving equipment, so as to improve the stability of polyester yarn transportation. At the same time, its tension also needs to be achieved by adjusting the tensioning roller. For example, a polyester yarn production traction force uniformity device with Chinese patent application number 202223470078.9 includes a fixed seat, a fixed plate, a fixed shaft, a traction roller, a limiting mechanism and a height adjustment mechanism; wherein the top side surface of the fixed seat is fixedly connected to a fixed plate, the top side surface of the fixed plate is fixedly connected to a fixed shaft, the surface of the fixed shaft is rotatably sleeved with a traction roller, and the surface of the traction roller is provided with a traction groove; the limiting mechanism includes a fixed frame, a top plate, an electric push rod, a connecting shaft and a limiting roller, and the fixed frame is fixedly connected to the top side surface of the fixed plate. This polyester yarn production traction uniformity device has a novel design and a simple structure. The motor drives the motor shaft to rotate, and the motor shaft drives the threaded column fixedly connected to the top to rotate. The threaded column then moves the inner cavity of the support tube with a threaded sleeve on the surface, thereby facilitating the adjustment of the height of the fixed seat to meet the traction needs of polyester yarns of different heights.

[0004] However, the heights of the two traction rollers cannot be adjusted separately and must be adjusted simultaneously. When the discharge position of the feeding device at the front of the polyester yarn is not the same as the receiving position of the subsequent receiving device at the rear of the polyester yarn, no matter how the heights of the two traction rollers are adjusted, they cannot correspond to the receiving position and the discharge position at the same time, and cannot be adjusted to the optimal position.

[0005] At the same time, since the motor is located below the fixed seat, a base is also installed below the fixed seat. Such a design itself raises the lowest position of the two traction rollers, and its adjustable range is limited, which affects its adjustment range and limits its scope of application. Utility model content:

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a traction device for polyester yarn production, whose two traction rollers can be adjusted separately so that their heights can correspond to the discharge position of the corresponding feeding equipment or the receiving position of the subsequent receiving equipment, thereby achieving optimal position adjustment.

[0007] The solution of the utility model to solve the technical problem is:

[0008] A traction device for polyester yarn production, comprising a fixed bottom plate, side support plates are fixed to the left and right parts of the top surface of the fixed bottom plate, lifting and adjusting mechanisms are installed on the outer side walls of the front and rear parts of the two side support plates, the lifting and adjusting mechanisms on the left and right sides correspond to each other, guide moving blocks are installed on the lifting blocks of the lifting and adjusting mechanisms, the guide moving blocks are inserted into corresponding vertical moving through grooves formed on the side support plates, and the two ends of the traction roller are movably connected to the two corresponding guide moving blocks through bearings;

[0009] A tensioning roller is provided between the two traction rollers, and a tensioning roller adjustment mechanism is installed on the middle outer wall of the side support plate between the two corresponding lifting and lowering adjustment mechanisms at the front and rear. A middle guide block is installed on the adjustment block of the tensioning roller adjustment mechanism. The middle guide block is inserted into the middle vertical adjustment groove formed in the middle of the corresponding side support plate, and the two ends of the tensioning roller are movably connected to the two middle guide blocks through bearings.

[0010] The lifting and adjusting mechanism includes horizontal fixed plates fixed on the outer side walls of the side support plates at the upper and lower parts of the vertical movable through groove. The two ends of the vertical lifting screw are movably connected to the two horizontal fixed plates through bearings. A lifting motor is fixed on the top surface of one of the horizontal fixed plates. The lifting motor drives the corresponding vertical lifting screw to rotate, and the lifting block is screwed on the corresponding vertical lifting screw.

[0011] The tensioning roller adjustment mechanism includes an intermediate horizontal fixed plate fixed on the outer side wall of the side support plate at the upper and lower parts of the middle vertical adjustment slot, and the two ends of the intermediate vertical lifting screw are movably connected to the two intermediate horizontal fixed plates through bearings.

[0012] The lifting block is formed with a connecting shaft in the middle of one side wall facing the guide moving block, and the adjusting block is also formed with a connecting shaft in the middle of one side wall facing the middle guide block. The connecting shaft is inserted into a socket formed in the middle of the side wall of the corresponding guide moving block or the middle guide block, and a vertical adjustment through hole is formed in the middle of the top surface of the socket, and an internal thread is formed on the top inner wall of the vertical adjustment through hole. The screw-connected block is screwed on the internal thread, and a clamping spring is inserted into the vertical adjustment through hole. The top end of the clamping spring exerts force on the bottom surface of the screw-connected block, and the bottom end of the clamping spring extends out of the vertical adjustment through hole and is in the socket, and the bottom end of the clamping spring presses against the top surface of the corresponding connecting shaft.

[0013] There is a distance between the top surface of the jack and the top surface of the connecting shaft;

[0014] The beneficial effects of the utility model are:

[0015] 1. Its two traction rollers can be adjusted separately, so that their heights can correspond to the discharging position of the corresponding feeding equipment or the receiving position of the subsequent receiving equipment, so as to achieve the best position adjustment.

[0016] 2. There is no base or other equipment at the bottom, so the lowest adjustment position of the two traction rollers can be sufficiently lowered to meet different conveying needs. Description of the drawings:

[0021] For example, see Figures 1 to 4 As shown, a traction device for polyester yarn production comprises a fixed bottom plate 10, side support plates 11 are fixed to the left and right parts of the top surface of the fixed bottom plate 10, lifting adjustment mechanisms 20 are installed on the outer side walls of the front and rear parts of the two side support plates 11, and the lifting adjustment mechanisms 20 on the left and right sides correspond to each other; a guide moving block 22 is installed on the lifting block 21 of the lifting adjustment mechanism 20, and the guide moving block 22 is inserted into the corresponding vertical moving groove 12 formed on the side support plate 11, and the two ends of the traction roller 30 are movably connected to the two corresponding guide moving blocks 22 through bearings;

[0022] Among them, the lifting and adjusting mechanism 20 includes a horizontal fixed plate 23 fixed on the outer wall of the side support plate 11 at the upper and lower parts of the corresponding vertical moving groove 12, and the two ends of the vertical lifting screw 24 are movably connected to the two horizontal fixed plates 23 through bearings. A lifting motor 25 is fixed on the top surface of one of the horizontal fixed plates 23, and the output shaft of the lifting motor 25 is a spline shaft, which is inserted into the spline hole at one end of the corresponding vertical lifting screw 24 and drives the corresponding vertical lifting screw 24 to rotate, and the lifting block 21 is screwed on the corresponding vertical lifting screw 24.

[0023] A tensioning roller 40 is provided between the two traction rollers 30, and a tensioning roller adjustment mechanism 50 is installed on the middle outer wall of the side support plate 11 between the two corresponding lifting and lowering adjustment mechanisms 20 at the front and rear. A middle guide block 52 is installed on the adjustment block 51 of the tensioning roller adjustment mechanism 50, and the middle guide block 52 is inserted into the middle vertical adjustment groove 13 formed in the middle of the corresponding side support plate 11, and the two ends of the tensioning roller 40 are movably connected to the two middle guide blocks 52 through bearings.

[0024] Among them, the tensioning roller adjustment mechanism 50 includes an intermediate horizontal fixed plate 53 fixed on the outer wall of the side support plate 11 at the upper and lower parts of the middle vertical adjustment slot 13, and the two ends of the intermediate vertical lifting screw 54 are movably connected to the two intermediate horizontal fixed plates 53 through bearings. An adjusting motor 55 is fixed to the top surface of one of the intermediate horizontal fixed plates 53, and the output shaft of the adjusting motor 55 is a spline shaft, which is inserted into the spline hole at one end of the corresponding intermediate vertical lifting screw 54, and drives the corresponding intermediate vertical lifting screw 54 to rotate, and the adjustment block 51 is screwed on the corresponding intermediate vertical lifting screw 54.

[0025] Furthermore, vertical protrusions 121 are fixed or formed on the front and rear inner walls of the vertical movable through groove 12, and vertical guide grooves are formed on the front and rear side walls of the guide movable block 22. The vertical protrusions 121 are inserted into the corresponding vertical guide grooves and cooperate with the vertical guide grooves.

[0026] Furthermore, a central vertical raised strip 131 is fixed or formed on the front and rear inner walls of the central vertical adjustment slot 13, and a central vertical guide groove is formed on the front and rear side walls of the central guide block 52. The central vertical raised strip 131 is inserted into the corresponding central vertical guide groove and cooperates with the central vertical guide groove.

[0027] Furthermore, the top surfaces of the two side support plates 11 are fixed to the bottom surface of the same upper horizontal connecting plate 15. The upper horizontal connecting plate 15 improves the connection firmness of the two side support plates 11 to prevent left and right swinging.

[0028] Furthermore, the lifting block 21 is formed with a connecting shaft 1 in the middle of one side wall facing the guide moving block 22, and the adjusting block 51 is also formed with a connecting shaft 1 in the middle of one side wall facing the middle guide block 52. The connecting shaft 1 is inserted into the insertion hole 2 formed in the middle of the side wall of the corresponding guide moving block 22 or the middle guide block 52, and a vertical adjustment through hole 3 is formed in the middle of the top surface of the insertion hole 2. An internal thread is formed on the top inner wall of the vertical adjustment through hole 3, and the screw block 4 is screwed on the internal thread. A compression spring 5 is inserted into the vertical adjustment through hole 3, and the top of the compression spring 5 is applied to the bottom surface of the screw block 4. The bottom end of the compression spring 5 extends out of the vertical adjustment through hole 3 and is in the insertion hole 2, and the bottom end of the compression spring 5 is pressed against the top surface of the corresponding connecting shaft 1. By rotating the screw block 4 and adjusting its height, the compression degree of the compression spring 5 can be adjusted.

[0029] Furthermore, there is a gap between the top surface of the jack 2 and the top surface of the connecting shaft 1;

[0030] The cross section of the connecting shaft 1 is rectangular, and the insertion hole 2 is rectangular, and the two are matched.

[0031] Furthermore, an elastic plate 6 is fixed to the bottom surface of the jack 2, and the bottom surface of the connecting shaft 1 is pressed against the top surface of the elastic plate 6;

[0032] The guide moving block 22 or the middle guide block 52 is close to the lifting block 21 or the adjusting block 51 against a side wall of the lifting block 21 or the adjusting block 51 (that is, there is a spacing between the guide moving block 22 or the middle guide block 52 and a side wall of the lifting block 21 or the adjusting block 51, and this spacing is generally 2 mm to 5 mm).

[0033] The regulating motor 55 and the lifting motor 25 in this embodiment can both be servo motors to ensure the accuracy of the lifting and lowering positions of the traction roller 30 and the tensioning roller 40 .

[0034] In this embodiment, the highest adjustable position of the traction roller 30 is lower than the highest adjustable position of the tension roller 40 , and the lowest adjustable position of the traction roller 30 is lower than the lowest adjustable position of the tension roller 40 .

[0035] In this embodiment, the two traction rollers 30 are formed with a plurality of corresponding annular guide grooves in front and back, which are used for guiding the conveying of polyester yarns.

[0036] When in use, it can realize the height adjustment of the corresponding traction roller 30 through the synchronous operation of two corresponding lifting motors 25 on the left and right;

[0037] Since the two traction rollers 30 can be adjusted individually, the height of the traction roller 30 can be adjusted to correspond to the discharging position of the corresponding feeding device or the receiving position of the subsequent receiving device, thereby achieving optimal position adjustment.

[0038] Through the synchronous operation of the two regulating motors 55, the height adjustment of the tensioning roller 40 can be achieved, so that it can be pressed against the polyester yarn conveyed between the two traction rollers 30 to adjust its conveying tension and ensure its normal conveying.

[0039] When this embodiment is in use, a connecting shaft 1 is formed in the middle of a side wall of the lifting block 21 facing the guide moving block 22, and a connecting shaft 1 is also formed in the middle of a side wall of the adjusting block 51 facing the middle guide block 52. The connecting shaft 1 is inserted into a socket 2 formed in the middle of the side wall of the corresponding guide moving block 22 or the middle guide block 52, and a vertical adjustment through hole 3 is formed in the middle of the top surface of the socket 2. An internal thread is formed on the top inner wall of the vertical adjustment through hole 3, and a screw block 4 is screwed on the internal thread. A clamping spring 5 is inserted into the vertical adjustment through hole 3, and the top end of the clamping spring 5 exerts on the bottom surface of the screw block 4, and the bottom end of the clamping spring 5 extends out of the vertical adjustment through hole 3 and is in the socket 2, and the bottom end of the clamping spring 5 is pressed against the top surface of the corresponding connecting shaft 1.

[0040] This structure allows that when the corresponding two lifting motors 25 or adjusting motors 55 are in use, there may be a small time difference when they are turned on, and there is a gap between the top surface of the socket 2 and the top surface of the connecting shaft 1. Therefore, it can be ensured that the tensioning roller 40 or the traction roller 30 can still be normally lifted and adjusted without getting stuck, thereby ensuring normal lifting, and the clamping spring 5 can ensure the clamping of the tensioning roller 40 or the traction roller 30 after the position is adjusted.

[0041] At the same time, in this embodiment, since there is no base or other equipment at the bottom, the lowest adjustment position of the two traction rollers can be sufficiently lowered, so it can meet the tensioning and conveying of the polyester yarn conveyed from a low position.

[0042] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
