Description

Technical Field

[0001] This utility model relates to the technical field of hose extrusion processing equipment, and in particular to a traction device. Background Technology

[0002] Hose typically consists of an inner liner, an intermediate layer, and an outer braided layer. The outer braided layer not only enhances structural strength but also improves the hose's corrosion resistance and abrasion resistance. During the production of the braided layer, after braiding, it is conveyed to an extrusion die, currently often using a traction device for transport.

[0003] However, when the braided layer is transported in the existing traction device, the portion of the braided layer between the two conveying structures is suspended in mid-air. Since the braided layer material is relatively soft, this suspended portion is prone to mutual compression and pre-piling, leading to damage. Furthermore, this portion of the braided layer between the two conveying structures also causes a lack of directionality in the transport of the braided layer, easily causing it to deviate from the preset traction path. Different sections of the braided layer will intersect and overlap, ultimately resulting in accumulation. Utility Model Content

[0004] The present invention aims to overcome the problem of braided layer accumulation caused by existing traction devices, and provides a traction device.

[0005] To achieve the above objectives, the present invention provides a traction device comprising a guiding mechanism, a support rod, and a conveying mechanism. One end of the support rod is connected to the guiding mechanism, the support rod passes through the conveying mechanism, and the other end of the support rod is connected to an extrusion die.

[0006] In one embodiment, the guiding mechanism includes a rotating member and a first bracket, the rotating member being mounted on the first bracket, and the support rod passing through the first bracket and connected to the rotating member.

[0007] In one embodiment, the rotating component includes at least two rotating bodies and a connecting member, wherein the rotating bodies are connected to each other via the connecting member, and the connecting member is connected to the support rod.

[0008] In one embodiment, the rotating body is a hemispherical rotating body.

[0009] In one embodiment, the rotating body is rotatably connected to the connecting rod, and the rotating body can rotate freely relative to the connecting rod.

[0010] In one embodiment, the guiding mechanism further includes a first rotating member and a second rotating member, both of which are mounted on the first bracket and are respectively mounted on the upper and lower ends of the support rod.

[0011] In one embodiment, the first rotating member and the second rotating member are respectively clearance-fitted with the rotating member.

[0012] In one embodiment, the traction device further includes a driver connected to the first rotating member and the second rotating member.

[0013] In one embodiment, the conveying mechanism includes a second support, a crossbeam, a drive member, a first track, and a second track. The crossbeam is mounted on the second support, the drive member is mounted on the crossbeam and connected to the first track, the second track is mounted on the second support, and the support rod passes through the interior of the second support.

[0014] In one embodiment, the traction device further includes a control box connected to the first track, the second track, the drive unit, and the driver.

[0015] In summary, this invention provides a traction device. By installing the support rod, it provides a traction path for the braided layer, preventing it from tangling and accumulating due to suspension or localized aggregation due to abnormal traction. Furthermore, the invention includes a guide mechanism upstream of the conveying mechanism. The rotating component expands the braided layer, addressing the issue of high internal stress. It also coordinates with the first and second rotating components to convey the braided layer, dispersing the tension and preventing excessive localized stress. This also offsets some of the rotational force experienced by the braided layer in the extrusion die, improving the transport stability and product uniformity.

[0031] To make the objectives and technical solutions of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] This invention provides a traction device that provides support and a traction path for the braided layer, preventing it from accumulating during transportation due to suspension or deviation from the path. Furthermore, before conveying the braided layer, the traction device pre-releases internal stress and provides a relatively stable stress environment, solving the problems of concentrated tension at the contact points between the track or roller and the braided layer, excessive localized stress affecting the product qualification rate of the braided layer, and the problem of excessive internal stress generated during the braiding process, which affects the performance and service life of the hose.

[0033] Figure 1 This is a schematic diagram of a traction device according to this utility model. Figure 1As shown, the traction device 1 includes a guiding mechanism 11, a support rod 13, and a conveying mechanism 12. One end of the support rod 13 is connected to the guiding mechanism 11, the support rod 13 passes through the conveying mechanism 12, and the other end of the support rod 13 is connected to the extrusion die 2. Preferably, the support rod 13 is horizontally arranged. The support rod 13 provides a transport path for the braided layer; the guiding mechanism 11 is used to release the internal stress of the braided layer 3 and provide pre-tension for the transport of the braided layer 3; while the conveying mechanism 12 provides the main force during the transport of the braided layer.

[0034] The guiding mechanism 11 includes a rotating component 111, a first rotating component 112, a second rotating component 113, and a first support 114. The rotating component 111 is mounted on the side of the first support 114 away from the conveying mechanism 12. The support rod 13 passes through the first support 114 and is connected to the rotating component 111. Both the first rotating component 112 and the second rotating component 113 are mounted on the first support 114. Preferably, the first rotating component 112 is positioned above the second rotating component 113. The first rotating component 112 and the second rotating component 113 are respectively mounted at the upper and lower ends of the support rod 13, and the first rotating component 112 and the second rotating component 113 are respectively clearance-fitted with the rotating component 111.

[0035] The first bracket 114 serves a supporting function. The first bracket 114 has pre-drilled holes for mounting the first rotating component 112 and the second rotating component 113. Both ends of the first rotating component 112 and the second rotating component 113 pass through the pre-drilled holes and are installed within them. Preferably, the centers of the first rotating component 112 and the second rotating component 113 are vertically aligned. The first rotating component 112 and the second rotating component 113 are connected to a driver 115, which provides power to the first rotating component 112 and the second rotating component 113, thereby driving them to provide the same force for the rightward transport of the braided layer. The driver 115 can be a rotary cylinder, etc. When using a rotary cylinder, it provides a rotational force to the first rotating component 112 and the second rotating component 113. The driver 115 can also be any other component capable of providing power to the first rotating component 112 and the second rotating component 113. The first rotating component 112 and the second rotating component 113 can be circular rollers. The upper and lower circular rollers rotate counterclockwise and clockwise, respectively, to provide the same force to the woven layer sleeved on the support rod 13, so that the woven layer can be smoothly transported to the conveying mechanism 12. The first rotating component 112 and the second rotating component 113 can also be other components with conveying functions.

[0036] Combination Figure 2 and Figure 1 It is understood that the rotating component 111 includes at least two rotating bodies 1111 and a connecting member 1112. The rotating bodies 1111 are connected to each other via the connecting member 1112, which is connected to the support rod 13. The rotating body 1111 expands the braided layer to avoid excessive local stress, thereby reducing the rotation of the braided layer in the extrusion die 2; and it also prevents the braided layer from accumulating and being squeezed. Preferably, the rotating body 1111 can be a hemispherical rotating body, which is used to uniformly expand the braided layer and has the characteristics of good conformability and low resistance. Furthermore, the rotating body 1111 is rotatably connected to the connecting member 1112 so that the rotating body 1111 can rotate relative to the connecting member 1112, such as using a universal joint or a ball joint. The rotatable nature of the rotating body 1111 transforms the sliding friction between the braided layer and the contact surface of the rotating body 1111 into rolling friction, thus optimizing the operation process of putting the braided layer on the rotating body 1111 and removing the braided layer from the rotating body 1111, and improving the convenience of operation.

[0037] It is worth noting that the force exerted by the rotating body 1111 on the braided layer sleeved thereon is less than the tension exerted by the first rotating member 112 and the second rotating member 113 on the braided layer, so as to ensure that the braided layer is transported smoothly.

[0038] The conveying mechanism 12 includes a second support 121, a crossbeam 122, a drive component 123, a first track 124, and a second track 125. The crossbeam 122 is mounted on the second support 121, and the drive component 123 is mounted on the crossbeam 122 and connected to the first track 124. The second track 125 is mounted on the second support 121, and a support rod 13 passes through the interior of the second support 121. The second support 121 provides support, and the crossbeam 122 connects to the drive component 123. The drive component 123 may be, but is not limited to, a cylinder, which moves the first track 124 vertically. The first track 124 is movable, while the second track 125 is fixed in position. The first track 124 and the second track 125 operate in opposite directions. The first track 124 and the second track 125 provide the same force in the same direction and of the same magnitude to the woven layer mounted on the support rod 13, ensuring that the woven layer moves smoothly along the preset traction direction.

[0039] The traction device 1 also includes a control box 14, which is installed at the bottom of the second bracket 121. The control box 14 is connected to the driver 115, the first track 124, the second track 125, and the drive component 123. The control box 14 provides power and control signals to each component to achieve stable transport of the woven layer. The control box 14 controls the driver 115 to drive the first conveyor 112 and the second conveyor 113 to operate at the same frequency, ensuring that the first conveyor 112 and the second conveyor 113 provide a consistent traction speed for the woven layer. At the same time, the control box 14 can also drive the drive component 123 to control the distance between the first track 124 and the second track 125, and coordinate the first track 124 and the second track 125 to provide the woven layer with a consistent traction speed as the first conveyor 112 and the second conveyor 113, so that the woven layer is transported in a stable state, so as not to affect the forming state of the woven layer in the extrusion die 2.

[0040] like Figure 3As shown, during the use of the traction device 1, the switch in the control box 14 is turned on, and the braided layer 3 is fitted onto the rotating body 1111. The rotatability of the rotating body 1111 facilitates the fitting operation. The braided layer 3 is then fitted onto the support rod 13 connected to the rotating body 1111. The control box 14 controls the operation of the driver 115, which provides power to the first rotating member 112 and the second rotating member 113. The first rotating member 112 and the second rotating member 113 will provide a consistent force to the braided layer 3. Under the action of the first rotating member 112 and the second rotating member 113, the braided layer moves along the support rod 13 to the conveying mechanism 12, while the rotating body 1111, under force balance, no longer rotates. Meanwhile, the control box 14 drives the first track 124 and the second track 125 to operate, and the control box 14 controls the drive component 123 to lower the first track 124. After the first track 124 moves to a suitable position, it will work in conjunction with the second track 125 to further transport the woven layer 3 to the extrusion die 2 for subsequent processing. The first rotating component 112 and the second rotating component 113 can buffer the changes in tension of the woven layer 3, avoiding the problem of excessive local stress caused by using the first track 124 and the second track 125 alone, and the tension distribution of the woven layer 3 is more uniform. In addition, the first track 124 and the second track 125 can provide a stable preload for the woven layer 3, which to a certain extent offsets or reduces the rotational force on the woven layer 3 in the extrusion die 2, improving the transportation stability and product uniformity of the woven layer 3.

[0041] In summary, this utility model provides a traction device. By installing the support rod 13, it provides a traction path for the braided layer 3, preventing the braided layer 3 from tangling and accumulating due to suspension or localized aggregation due to abnormal traction. Furthermore, this utility model provides a guide mechanism 11 upstream of the conveying mechanism 12, using the rotating component 111 to expand the braided layer 3, thus solving the problem of high internal stress in the braided layer 3. It also coordinates with the first rotating component 124 and the second rotating component 125 to convey the braided layer 3, dispersing the tension of the braided layer 3, avoiding excessive localized stress, and offsetting part of the rotational force experienced by the braided layer 3 in the extrusion die 2, thereby improving the transport stability and product uniformity of the braided layer 3.
