[0002] In the tungsten wire winding support process of the infrared lamp tube manufacturing, the wire transmission structure is crucial to the processing of the rigid assembly (formed by the combination of tungsten wire, positioning ring and mandrel, etc.), but the traditional process relies on manual operation to transport the rigid assembly into the winding machine, and the positioning ring is installed on the rigid assembly outside for limiting the position of the rigid assembly in the middle of the glass tube.

[0003] Further, when winding the tungsten wire (rigid assembly), a continuous traction transmission structure is added for traction of the tungsten wire for equal interval movement, and it is necessary to ensure continuity and stability during this movement;

[0004] At the same time, since the tungsten wire and other metal materials have thermal expansion, the rigid assembly will heat up due to friction or mechanical stress during the winding process, which will cause the tungsten wire to elongate and the diameter to increase, resulting in changes in the spacing between the originally equally spaced positioning rings, which are no longer uniform, and the rigid assembly cannot be cooled in time after winding to ensure the accuracy of the positioning ring position. Therefore, the present application provides a solution. SUMMARY

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the application.

[0028] Embodiment one: please refer to Figures 1-6 As shown in the figure, for the problem that the rigid assembly in the prior art generates heat due to friction or mechanical stress, makes the tungsten wire elongate and the diameter become thick, etc., causes the spacing between the originally equidistantly wound limiting rings to change and no longer be uniform, the following scheme can be used to solve the problem.

[0029] The wire transmission structure in the tungsten wire winding support process in the embodiment comprises a wire transmission frame 2 and a winding machine 1 installed at the middle part of the wire transmission frame 2, the wire transmission frame 2 is provided with an entry traction base plate 3 on the left side of the winding machine 1, the wire transmission frame 2 is provided with an exit traction base plate 4 on the right side of the winding machine 1, and a traction assembly for traction of the rigid assembly is arranged above the exit traction base plate 4.

[0030] It needs to be explained here that the rigid assembly comprises tungsten wire, positioning ring and mandrel, etc. combined together, the rigid assembly is conveyed to the inside of the winding machine 1 through the transmission element, the positioning ring is wound on the rigid assembly, and the limiting ring is equidistantly wound on the rigid assembly and used for limiting the position of the rigid assembly installed in the middle part of the glass tube.

[0031] The winding machine 1 is a functional instrument having the function of equidistantly winding the limiting ring on the outer wall of the rigid assembly in the prior art, belongs to the prior art, and will not be described in detail here.

[0032] The traction assembly comprises two groups of control plates 62 in sliding fit with the exit traction base plate 4, the two groups of control plates 62 are symmetrically arranged relative to the center line of the exit traction base plate 4, the side wall of the control plate 62 is fixedly provided with a pneumatic cylinder 61 fixedly connected with the exit traction base plate 4, and the top wall of the control plate 62 is fixedly provided with a plurality of groups of traction plates 63 which are uniformly distributed on the control plate 62.

[0033] It needs to be explained here that the distance of extension of the traction plate 63 driven by the pneumatic cylinder 61 each time is the same as the distance between the two limiting rings on the rigid assembly, so as to avoid the limiting ring from contacting the lifting plate 73 due to equidistant movement and affecting the safety and continuity of the equipment work.

[0034] The inner wall of the traction plate 63 is provided with a piston groove 67 and a movable groove, a piston plate 69 is slidably arranged in the piston groove 67, a connecting column is fixedly arranged on the side wall of the piston plate 69, a push spring 68 is sleeved on the outer wall of the connecting column, the end of the connecting column extends into the movable groove and is fixedly connected with a traction head 610, the traction head 610 is in sliding fit with the movable groove, the side wall of the traction head 610 close to the rigid assembly is in arc structure, and the arc structure of the traction head 610 is provided with a rubber pad.

[0035] The side wall of the traction plate 63 away from the rigid assembly is vertically provided with a delivery pipe 65 in communication with the piston groove 67, the outer wall of the delivery pipe 65 is fixedly provided with a flow control valve 66, and a plurality of groups of delivery pipes 65 on the same side are connected through a gas collecting pipe 64.

[0036] The inner wall of the piston groove 67 is symmetrically provided with a vent hole 611, which is located on the side wall of the piston plate 69 close to the conveying pipe 65. The output end of the vent hole 611 is provided with a cooling pipe 612 for eliminating the stress of the rigid assembly. The outer wall of the cooling pipe 612 is fixedly provided with a cooling control valve;

[0037] That is, the cooling control valve is opened, the gas in the piston groove 67 rapidly flows into the cooling pipe 612 through the vent hole 611, and then accurately blows to the connection between the limiting ring and the rigid assembly through the cooling pipe 612. By blowing gas to this part, the heat generated by the friction or mechanical stress of the rigid assembly during the winding process of the limiting ring is timely cooled;

[0038] A plurality of groups of electric push rods 71 are fixedly installed on the top wall between the two regulating plates 62. The top of the electric push rod 71 is fixedly provided with a lifting rod 72. The top of the lifting rod 72 is fixedly provided with a lifting plate 73 for lifting the rigid assembly. The lifting plate 73 is arc-shaped;

[0039] That is, the electric push rod 71 is controlled to move upwardly with the lifting plate 73, and the lifting plate 73 is adjusted to a suitable height position. When the two traction heads 610 are separated, the top of the lifting plate 73 can just lift the rigid assembly to provide stable support for the rigid assembly;

[0040] In this embodiment, after the winding limiting ring process is completed, the rigid assembly is output from the winding machine 1. At this time, the lifting plate 73 is in a preset position to stably support the output rigid assembly, providing a basis guarantee for subsequent operations and ensuring the stable position of the rigid assembly in the initial stage;

[0041] A large amount of gas is introduced into the rear gas collecting pipe 64, and the flow control valve 66 is opened at the same time. The flow control valve 66 plays a role in accurately adjusting the flow of gas, ensuring that a large amount of gas can enter the subsequent piston groove 67 in an equal amount, providing a stable and controllable power source for the movement of the subsequent piston plate 69;

[0042] After a large amount of equal gas enters the piston groove 67, it accumulates in the piston groove 67 and continuously exerts a pressing force on one side of the piston plate 69. The piston plate 69 moves to one side under the action of the force, thereby pushing the connecting column to move close to the rigid assembly. The movement of the connecting column drives the two groups of traction heads 610 to act synchronously, finally realizing the clamping of the rigid assembly;

[0043] At the moment when the two groups of traction heads 610 begin to clamp the rigid assembly, the extension end of the electric push rod 71 rapidly contracts, driving the lifting plate 73 and the lifting head to contract downwardly. In order to avoid collision between the limiting ring and the lifting plate 73 during the movement of the rigid assembly, the smooth operation and safety of the equipment are ensured;

[0044] After the rigid assembly is clamped, the extension end of the air cylinder 61 begins to stretch, and the bottom of the regulating plate 62 is in sliding fit with the traction bottom plate 4. Under the action of the pushing of the air cylinder 61 and the sliding fit, the regulating plate 62 moves away from the winding machine 1, and the movement of the regulating plate 62 drives the rigid assembly to pull outwards by a certain distance, so as to realize the accurate positioning and equidistance movement of the rigid assembly in the conveying process.

[0045] When the equidistance movement of the rigid assembly is completed, the electric push rod 71 is first controlled to drive the lifting plate 73 to move upwards, and the lifting plate 73 is adjusted to a suitable height position. When the two traction heads 610 are separated, the top of the lifting plate 73 can just lift the rigid assembly, providing stable support for the rigid assembly to prevent it from shaking or position deviation in the subsequent operation.

[0046] After the lifting plate 73 completes the lifting of the rigid assembly, the cooling control valve is opened. At this time, the gas in the piston groove 67 rapidly enters the cooling pipe 612 through the air hole 611, and then accurately blows to the connection between the limiting ring and the rigid assembly through the cooling pipe 612. By blowing air to this part, the heat generated by the rigid assembly due to friction or mechanical stress during the winding of the limiting ring is timely cooled, ensuring the accuracy of the position of the limiting ring and avoiding deformation or position deviation of the limiting ring due to heat, thereby improving the overall quality of the product.

[0047] After the cooling operation is completed, the extension end of the air cylinder 61 is controlled to reset, and the regulating plate 62 is reset, preparing for the equidistance conveying of the rigid assembly next time. Then, the equidistance conveying of the rigid assembly is continued according to the above steps. At the same time, the bottom limiting roller and the side limiting roller cooperate with each other. The bottom limiting roller limits the rigid assembly from the bottom, and the side limiting roller restricts it from the side. The two together ensure the stability and continuity of the rigid assembly during the winding conveying process, ensuring the smooth progress of the entire production process.

[0048] Example Two: Please refer to Figure 1 , Figure 6 for supplementary description based on Example One.

[0049] The traction bottom plate 3 is provided with a conducting member for conducting the rigid assembly. The conducting member includes a traction frame 51, and a plurality of bottom conveying rollers 52 for guiding the conveying of the rigid assembly are horizontally installed on the traction frame 51. A plurality of side conveying rollers 53 for guiding the conveying of the rigid assembly are also symmetrically and vertically installed on the traction frame 51.

[0050] That is, the side conveying rollers 53 are fixedly connected with the traction frame 51 through bolts, so as to adjust the vertical distance between the two side conveying rollers 53, facilitating the conduction of rigid assemblies of different diameters.

[0051] In the present application, it can be known from the combination of example one and example two that: in the conveying process of the rigid assembly, the lifting plate 73 initially supports its stable starting state, the piston plate 69 pushes the traction head 610 to synchronously clamp to ensure uniform stress and reduce shaking, the electric push rod 71 timely adjusts the position of the lifting plate 73 to avoid collision, the bottom conveying roller 52 and the side conveying roller 53 constrain the assembly from the bottom and the side, and multiple measures are taken to ensure stable conveying. The cylinder 61 cooperates with the control plate 62 to realize equidistant movement and can be operated in a cycle, the process is coherent to ensure continuity, the cooling control valve is opened after equidistant movement, the gas is blown to the connection through the cooling pipe 612, the heat is reduced to prevent thermal deformation from causing the limit ring to deviate, the position is ensured to be accurate, and the product quality is improved.
