Description

Technical Field

[0001] The utility model relates to the technical field of synthetic fiber production, in particular to a double-heat-track hot box head-lifting device in the production process of acrylic filaments. Background Art

[0002] In the production process of synthetic fibers, it is generally necessary to heat and shape the fibers to ensure that the physical indicators of the fibers meet the requirements. The most common method is to use an open hot rail hot box heating method, where the fibers are heated by direct contact with the hot rail. This method is simple to operate and widely used.

[0003] Due to the molecular structure characteristics of acrylic filaments, a longer drying and shaping device is required. If a horizontally set hot box heating method is used, the floor space is large. The method of setting two hot boxes in a vertical direction for simultaneous heating and shaping saves the horizontal space of the site on the one hand, and on the other hand, the use of double heat pipes for simultaneous heating and shaping processes further reduces the size of the equipment and improves production efficiency. However, due to the large height of the hot box, this setting method requires the cooperation of multiple operators to simultaneously lift the acrylic filaments to the top of the two hot boxes, and then heat and shape them to complete the lifting work. The operation is complicated and the efficiency is low. Utility Model Content

[0025] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0026] like Figure 1-Figure 7As shown, the present application provides a dual hot rail hot box head lifting device, which is used in conjunction with a first hot rail hot box 1 and a second hot rail hot box 2. The head lifting device of the present application mainly includes: a driving component, the fixed part of the driving component is fixedly connected to a carrier (such as a wall, a fixed support frame, etc.), and a head lifting pendulum 4 is movably connected to the moving part of the driving component. The first hot rail hot box 1 and the second hot rail hot box 2 are vertically arranged on both sides of the head lifting pendulum 4, and the head lifting pendulum 4 can be lifted and lowered in the vertical direction under the drive of the driving component. Preferably, the first hot rail hot box 1 and the second hot rail hot box 2 are arranged in an eight-shaped shape on both sides of the head lifting pendulum 4, and the lifting direction of the head lifting pendulum 4 is parallel to the length direction of the first hot rail hot box 1.

[0027] The driving assembly is a rodless cylinder 3, which includes a long rod-shaped fixed portion arranged along the vertical direction and fixedly connected to the carrier, and a sliding block 31 slidably connected to the long rod-shaped fixed portion, and the sliding block 31 is rotatably connected to the head-lifting pendulum 4. The long rod-shaped fixed portion of the rodless cylinder 3 is arranged obliquely downward parallel to the first hot rail type hot box 1, and the driving block 31 drives the head-lifting pendulum 4 to rise and fall synchronously along the length direction parallel to the first hot rail type hot box 1.

[0028] The lifting head pendant 4 is a rod-shaped structure, and the two ends of the rod-shaped structure are respectively provided with a wire inlet end 41 and a wire outlet end 42 for hanging the silk thread 14. The lifting head pendant 4 is located at the back between the wire inlet end 41 and the wire outlet end 42, and is rotatably connected through the above-mentioned sliding block 31 through a rotating shaft, and the wire outlet end 42 is set upward, and the wire inlet end 41 is set downward. The above-mentioned wire outlet end 42 and wire inlet end 41 are both cylinders with through holes, and the surface of the cylinder is provided with an annular groove. The bottom ends of the wire outlet end 42 and the wire inlet end 41 are respectively fixed at the two ends of the lifting head pendant, and the silk thread 14 is located in the annular grooves of the wire outlet end 42 and the wire inlet end. The lifting head pendant 4 is rotatably connected to the sliding block 31 near the middle position, and the specific structure of the rotatable connection is: the lifting head pendant 4 is provided with an elastic member near the middle position for keeping it in a tilted upward state. The elastic member of the present application adopts a torsion spring, one end of the elastic member is fixed on the rod-shaped structure of the lifting head pendulum 4, and the other end of the elastic member is fixed on the rotating shaft of the lifting head pendulum 4 and the sliding block 31. The elastic member has elastic deformation potential energy to keep the lifting head pendulum 4 in an inclined upward setting state, so that the lifting head pendulum 4 will not swing to a vertical downward state due to the gravity of one end.

[0029] In addition, a limit piece 43 extending toward the sliding block 31 is integrally formed on the lifting head rocker 4 below the rotational connection between the lifting head rocker 4 and the sliding block 31. The limit piece 43 is cylindrical. When the lifting head rocker 4 is elastically rotated to the initial state through the elasticity of the elastic member, the outer peripheral wall of the limit piece 43 abuts against the surface of the driving block 31 to stop, which can avoid continuous rotation in the reset direction, thereby further ensuring that the lifting head rocker 4 is in a tilted state.

[0030] like Figure 1-Figure 7 As shown, the top of the rodless cylinder 3 is provided with a guide assembly, which includes an arc-shaped guide plate 6 fixedly connected to the top of the rodless cylinder 3. The position of the arc-shaped guide plate is higher than the top of the first and second hot rail hot boxes, and the arc-shaped guide groove 62 is formed on the side of the end of the arc-shaped guide plate 6 away from the rodless cylinder 3 toward the top of the hot rail hot box, and the end of the arc-shaped guide plate 6 is set to a hook shape, and the side of the lifting head pendulum 4 close to the wire outlet end 42 is provided with a guide wheel 61 suitable for the arc-shaped guide plate 6, and the guide wheel 61 is arranged on the rod-shaped structure of the lifting head pendulum 4 below the wire outlet end 42. An annular groove is provided on the outer peripheral wall of the guide wheel 61, and the side wall of the arc-shaped guide groove of the arc-shaped guide plate 6 can abut against the annular groove, so that the guide wheel 61 can move at the bottom of the arc-shaped guide groove; the end of the arc-shaped guide plate 6 away from the rodless cylinder 3 is set to a hook shape, which can prevent the guide wheel 61 from moving to the hook shape and continuing to move, thereby detaching from the arc-shaped guide plate.

[0031] A top wire guide wheel 5 is fixedly arranged on the top of the sliding block 31 along the length direction of the rodless cylinder 3, and the straight-line distance between the top wire guide wheel 5 and the sliding block 31 is smaller than the straight-line distance between the wire outlet end 42 and the sliding block 31. The top wire guide wheel 5 can prevent the wire 14 between the wire input end 41 and the wire outlet end 42 on the lifting head pendulum 4 from running off during the movement.

[0032] like Figure 1-Figure 7 As shown, the first hot rail 15 and the second hot rail 23 used for heating and shaping of the first hot rail type hot box 1 and the second hot rail type hot box 2 are open and placed in the corresponding box body, that is, the wire 14 to be heated can directly contact the first hot rail 15 and the second hot rail 23. The first hot rail type hot box 1 has a first wire outlet 11 at the top and a first wire inlet 12 at the bottom, and the second hot rail type hot box 2 has a second wire inlet 21 at the top and a second wire outlet 22 at the bottom, and the first wire outlet 11 and the first wire inlet 12 are connected to the first hot rail 15 of the first hot rail type hot box 1, and the second wire inlet 21 and the second wire outlet 22 are connected to the second hot rail 23 of the second hot rail type hot box 2. The first hot rail type hot box 1 has an input roller 9 on the side, and the second hot rail type hot box 2 has an output roller 10 on the side. A wire suction gun 13 is provided between the input roller 9 and the output roller 10. The wire suction gun is used to suck out the wire 14 from the input roller 9 and then wind it around the wire input end 41 on the lifting head pendulum 4, the top wire guide wheel 5, and the wire output end 42 on the lifting head pendulum 4 in sequence. After the above-mentioned wire 14 rises to a preset position, the wire suction gun 13 winds the wire 14 located at the bottom between the wire suction gun 13 and the wire output end 42 around the output roller 10.

[0033] In addition, a wire guide 7 is fixedly provided at the wire outlet and the wire inlet of the first hot rail type heat box 1 and the second hot rail type heat box 2, and an annular groove for accommodating the wire 14 is opened on the surface of the wire guide 7.

[0034] Furthermore, an eight-shaped guide plate 8 is fixedly provided at the first wire outlet 11, the first wire inlet 12, the second wire inlet 21, and the second wire outlet 22. The eight-shaped guide plate 8 is provided with a recessed opening for accommodating the wire 14, and the recessed opening faces the direction of the wire 14. The wire guide 7 and the eight-shaped guide plate 8 are used to prevent the wire 14 from deviating and ensure that the wire 14 is exactly located in the corresponding hot rail.

[0035] like Figure 1-Figure 4 As shown, when the lifting head pendulum 4 is in the initial position, that is, the wire outlet end 42 of the lifting head pendulum 4 faces upward and toward the second hot rail type heat box 2, and the wire inlet end 41 of the lifting head pendulum 4 faces downward and close to the first wire inlet 12 of the first hot rail type heat box 1, the operator uses the wire suction gun 13 to lead the wire 14 from the input roller 9, and makes the wire 14 pass through the wire guide 7 at the bottom of the first hot rail type heat box 1, the eight-shaped guide plate 8 at the first wire inlet 12 in sequence. , the wire inlet end 41 of the lifting head pendulum 4, and the top wire guide wheel 5 are pulled out from the wire outlet end 42 of the lifting head pendulum 4, and the wire suction gun is not removed at the same time, the rodless cylinder 3 is started, and the sliding block 31 drives the lifting head pendulum 4 to rise, and the wire 14 between the output roller 9 and the wire inlet end 41 on the lifting head pendulum 4 and the top wire guide wheel 5 rises synchronously, and the wire 14 between the top wire guide wheel 5 and the wire outlet end 42 on the lifting head pendulum 4 and the wire suction gun 13 also rises. The lifting head pendulum 4 rises until the guide wheel 61 touches the bottom of the arc guide groove of the arc guide plate 6. During the rising process of the lifting head pendulum 4, due to the action of the elastic body and the limit block 43, it is kept in the initial tilted state during the rising process.

[0036] like Figure 1-Figure 4 As shown in the figure, when it continues to rise, due to the guiding effect of the arc guide plate 6, the lifting head swing member 4 swings along the arc guide plate 6, and the elastic member is subjected to external force and deforms. When the sliding block 31 rises to the top, the lifting head swing member 4 swings to a horizontal position under the guidance of the arc guide plate 6, and the guide wheel 61 of the lifting head swing member 4 falls into the hook at the end of the arc guide plate 6. At the same time, the top wire guide wheel 5 on the sliding block 31 also rises to the top of the rodless cylinder 3 along with the driving block 31.

[0037] At this time, the wire at the wire entry end 41 of the lifting head pendulum 4 is close to the wire guide 7 at the first wire outlet 11 of the first hot rail type heat box 1, and the wire 14 at the wire entry end 41 enters the annular groove of the wire guide 7 through the swing of the lifting head pendulum 4, and falls into the concave opening of the eight-shaped guide plate 8 along the annular groove of the wire guide 7, so that the wire 14 in the first hot rail type heat box 1 is just located in its first hot rail 15. At the same time, the wire 14 at the wire outlet end 42 of the lifting head pendulum 4 passes through the wire guide 7 at the top of the second hot rail type heat box 2 in the same way as described above, and falls into the concave opening of the eight-shaped guide plate 8 at the top of the second hot rail type heat box 2. At this time, the wire suction gun 13 will pass the wire suction gun 13 and the wire outlet end 42 near the bottom through the wire guide 7 at the bottom of the second hot track type hot box 2, and fall into the recessed mouth of the eight-shaped guide plate 8 at the bottom of the second hot track type hot box 2. At this point, the wire 14 in the second hot track type hot box 2 is just located in its second hot rail 23, and the wire suction gun 13 will wind the wire 14 between the second wire outlet 22 of the second hot track type hot box 2 and the wire suction gun 13 to the output roller 10 for output. In this way, the wire 14 is simultaneously raised in the first hot track type hot box 1 and the second hot track type hot box 2, and then the wire heating and shaping process is completed.

[0038] Furthermore, the first hot track heat box 1 and the second hot track heat box 2 have the same or different lengths, and the first hot track heat box 1 and the second hot track heat box 2 have the same or different temperature settings to meet the process requirements of silk threads of different deniers and various silk threads.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
