Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to a mobile trolley platform. Background Technology

[0002] In the manufacturing process of power, communication, and special cables, to protect the cable core and impart specific properties (such as waterproofing, shielding, flame retardancy, and mechanical protection), one or more layers of wrapping tape (such as aluminum-plastic composite tape, steel-plastic composite tape, etc.) are usually wrapped around the cable core. The wrapping process is one of the key technologies for achieving this.

[0003] The wrapping process is based on equipment with torsional force in the cable production line, such as a stranding machine, which can generate torsional force on the core wire. When the wrapping tape is introduced at a certain angle, it can be accurately wrapped around the surface of the core wire.

[0004] In practical use, to ensure the accuracy of the lead-out angle, the wrapping tape roll is usually limited, including limits on both sides of the wrapping tape roll and limits on the lead-out direction. When a new wrapping tape roll needs to be replaced, the limit structures on both sides of the wrapping tape roll need to be disassembled before a new wrapping tape roll can be installed. This process is very complicated and reduces the overall cable production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mobile baggage platform that solves the technical problem of complex baggage replacement processes in existing baggage equipment.

[0006] A mobile trolley platform according to an embodiment of the present utility model includes a support platform and a roll-up mechanism disposed on the top of the support platform. A guide mechanism is provided on one side of the support platform, and an elastic pressure strip is provided on the other side of the support platform. The unwinding mechanism includes a lower turntable and an upper turntable. A circular channel is provided in the middle of the support platform. The lower turntable is installed in the circular channel, and a compression elastic element is provided between the bottom of the circular channel and the lower turntable. The upper turntable is located on the upper side of the support platform, and a gap is left between the upper turntable and the support platform. The elastic pressure strip is inserted into the gap.

[0007] The technical principle of this utility model is as follows: Before use, first disassemble the upper turntable, press multiple wrapping tape rolls into the circular channel, and then reinstall the upper turntable; manually pull out the wrapping tape rolls again, and wrap them onto the core wire through the guide mechanism, and the cable production line can be started normally.

[0008] When replacing a new wrapping tape roll, simply pull the elastic strip out between the lower and upper turntables. The new wrapping tape roll, located in the circular channel, will be pushed upwards by the compressed elastic element until it contacts the upper turntable. At this point, release the elastic strip to allow it to press back onto the wrapping tape roll. Then, manually pull the wrapping tape roll out again, and wrap it onto the core wire through the guide mechanism. Then, continue to start the entire cable production line.

[0009] In this way, the wrapping tape rolls only need to be refilled periodically, eliminating the need for frequent replacements. The wrapping tape rolls can be replenished during cable equipment maintenance, reducing their impact on the overall cable production efficiency.

[0010] Compared with the prior art, this utility model has the following advantages: by using a circular channel in conjunction with a lower turntable with a compression elastic element, as well as an upper turntable and an elastic pressure strip, it solves the technical problem of the complex process of changing the wrapping tape roll in existing bagging equipment.

[0011] Furthermore, the support platform is provided with a support rod around the circular channel. The support rod is connected to the upper turntable. The support rod is positioned to avoid the lead-out direction of the unwinding mechanism and the deformation range of the elastic pressure strip.

[0012] Furthermore, the upper turntable includes a mounting bearing and a rotating disk fixed on the inner ring of the mounting bearing. The outer ring of the mounting bearing is connected to a support rod. One side of the rotating disk has a protruding edge, and the other side of the rotating disk has a retaining ring. The retaining ring and the protruding edge are respectively engaged with the two sides of the inner ring of the mounting bearing.

[0013] Furthermore, the lower turntable includes a base and a rotating disk, with annular grooves provided on the top of the base and the bottom of the rotating disk, and rollers evenly distributed between the two annular grooves.

[0014] Furthermore, a compression elastic element is provided between the center of the base and the center of the bottom of the circular channel, and telescopic rods are evenly distributed circumferentially between the base and the circular channel.

[0015] Furthermore, a hinge shaft is provided between the elastic pressure strip and the support platform, and a support plate is provided on one side of the elastic pressure strip on the support platform, with a spring component provided between the support plate and the elastic pressure strip.

[0016] Furthermore, the upper turntable is provided with a limiting hole at its center, and a limiting screw is installed in the limiting hole, which can move along the limiting hole.

[0017] Furthermore, a limiting shaft is provided at the center of the lower turntable, and the limiting shaft coincides with the axis of the limiting screw.

[0018] Furthermore, the top of the limiting shaft is provided with an annular notch, and the bottom of the limiting screw is provided with an annular hook, which engages with the annular notch. Attached Figure Description

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1 like Figure 1 The mobile cable tray platform shown includes a support platform 1 and an unwinding mechanism 11 located on top of the support platform 1. A guide mechanism 12 is provided on one side of the support platform 1, and an elastic pressure strip 13 is provided on the other side of the support platform 1. In actual use, the mobile cable tray platform is located on one side of the cable production line, specifically on the side of the stranding machine 2. Therefore, traction force and rotational force can be provided here to realize the winding of the covering tape. The guide mechanism 12 is located on the side close to the stranding machine 2 to guide the covering tape into the stranding machine 2.

[0029] Specifically, the wrapping tape needs to be wrapped and fixed at one end to the core wire that needs to be wrapped while the stranding machine 2 is stopped. Then, start the stranding machine 2. Only then can the wrapping tape continue to be wrapped at the corresponding core wire position.

[0030] like Figure 2 As shown, the unwinding mechanism 11 includes a lower turntable 3 and an upper turntable 4. A circular channel 14 is provided in the middle of the support platform 1. The lower turntable 3 is installed in the circular channel 14, and a compression elastic element 141, which can be a compression spring, is provided between the bottom of the circular channel 14 and the lower turntable 3. The upper turntable 4 is located on the upper side of the support platform 1, and there is a gap between the upper turntable 4 and the support platform 1. The elastic pressure strip 13 is inserted into the gap. The function of the elastic pressure strip 13 here is to prevent the covering tape roll from automatically loosening and to prevent the covering tape roll located on the lower side from moving upward.

[0031] like Figure 2-3 As shown, the support platform 1 is provided with a support rod 41 around the circular channel 14. The support rod 41 is connected to the upper turntable 4. The support rod 41 is positioned to avoid the lead-out direction of the unwinding mechanism 11 and the deformation range of the elastic pressure strip 13.

[0032] like Figure 2 As shown, the upper turntable 4 includes a mounting bearing 42 and a rotating disk 43 fixed on the inner ring of the mounting bearing 42. The outer ring of the mounting bearing 42 is connected to the support rod 41. One side of the rotating disk 43 is provided with an integrally formed protrusion 431, and the other side of the rotating disk 43 is provided with a retaining ring 432 for connection. The retaining ring 432 and the protrusion 431 are respectively engaged on both sides of the inner ring of the mounting bearing 42, so that the rotating disk 43 can rotate together with the wrapping tape roll.

[0033] like Figure 2 , 4 As shown, the lower turntable 3 includes a base 31 and a rotating disk 32. The top of the base 31 and the bottom of the rotating disk 32 are provided with annular grooves 311, and rollers 321 are evenly distributed between the two annular grooves 311, so that the rotating disk 32 can rotate together with the wrapping tape roll.

[0034] like Figure 2 As shown, a compression elastic element 141 is provided between the center of the base 31 and the bottom center of the circular channel 14. Telescopic rods 142 are evenly distributed circumferentially between the base 31 and the circular channel 14. The telescopic rods 142 are formed by two hollow tube segments sleeved together, which are used to maintain the accuracy of the moving direction of the base 31.

[0035] like Figure 5 As shown, a hinge shaft 131 is provided between the elastic pressure strip 13 and the support platform 1. The support platform 1 is fixed with a support plate 132 on one side of the elastic pressure strip 13. A spring member 133 is connected between the support plate 132 and the elastic pressure strip 13. The spring member 133 is a tension spring.

[0036] Example 2 like Figure 6-7 As shown, the difference between this embodiment and embodiment 1 is that: the rotating disk 43 is provided with a limiting hole 44 at its center, and a limiting screw 45 is installed in the limiting hole 44. The limiting screw 45 can move along the limiting hole 44. The rotating disk 32 is provided with a limiting shaft 33 at its center. The axis of the limiting shaft 33 coincides with that of the limiting screw 45. Specifically, the top of the limiting shaft 33 is provided with an annular slot 331, and the bottom of the limiting screw 45 is provided with an annular hook 451. The annular hook 451 is engaged with the annular slot 331.

[0037] This embodiment is applicable to a wrapping tape roll with a hollow tube in the center. The circumferential rotation of the wrapping tape roll is more stable. When a wrapping tape roll is used up, pull out the limiting screw 45, push out the used hollow tube, then pull out the elastic pressure strip 13, and the wrapping tape roll on the lower side will automatically move up. Finally, the limiting screw 45 can be re-engaged.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
