Description

Technical Field

[0001] This utility model relates to the field of cable production equipment technology, and in particular to a convenient and quick cable laying device. Background Technology

[0002] Cables are wire products used to transmit electrical energy, information, and realize electromagnetic energy conversion. They can be defined as: an assembly consisting of one or more insulated cores, and their respective possible sheaths, overall protective layers, and outer sheaths. Cables may also have additional uninsulated conductors. In the extrusion production of communication cables, the inner core of the communication cable is coiled on the reel of the cable-laying device. The ends of the cable cores are stretched by the extruder, and the extruder fits the insulating outer sheath onto the inner core. The cable-laying device is required during the cable laying process.

[0003] However, existing wire feeding devices generally achieve the rotation of the wire feeding drum during wire feeding through a central rotating shaft. This structure is not convenient for loading and unloading the wire feeding drum, increases the labor intensity of operators, and reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a convenient and quick cable laying device that facilitates the loading and unloading of the cable laying drum, improves the stability during cable laying, and reduces the labor intensity of operators.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A convenient and fast cable feeding device includes a feeding frame and a feeding drum. The feeding frame includes an upper pressure plate and a lower roller assembly. The lower roller assembly includes a fixed roller assembly and a movable roller assembly. The movable roller assembly slides along the direction close to or away from the fixed roller assembly. The side plates at both ends of the feeding drum abut against the lower roller assembly. The upper pressure plate is connected to a pressure plate lifting assembly and drives it to move up and down. One or more pressure rollers are connected below the upper pressure plate. The pressure rollers abut against the upper side plates of the feeding drum, and the length of the pressure rollers is not less than the maximum distance between the fixed roller assembly and the movable roller assembly.

[0007] By adopting the above technical solution, the two end plates of the wire feeding drum abut against the lower roller assembly, realizing the rotation of the wire feeding drum for feeding; the pressure roller abuts against the upper side of the side plate of the wire feeding drum, improving the stability during wire feeding; and by setting up fixed roller assembly and movable roller assembly, in combination with the length of the pressure roller, the adaptability to wire feeding drums of different sizes can be improved, and the versatility of the device can be improved.

[0008] Furthermore, both the fixed wheel set and the movable wheel set include a pair of abutting wheels, with a passage trolley located in the middle between the abutting wheels. The passage trolley is equipped with at least one lifting component to lift or lower the wire feeding cylinder from the abutting rollers.

[0009] By adopting the above technical solution, the trolley avoids the use of a traveling crane, reduces costs, and avoids interference with the upper pressure plate, thus improving the convenience of loading and unloading the device.

[0010] Furthermore, the wire feeding frame is provided with a feeding rack and a discharging rack on both sides. Both the feeding rack and the discharging rack include symmetrically arranged placement beams. The trolley lifts the wire feeding drum with full material on the feeding rack and places it into the wire feeding frame, and lifts the empty wire feeding drum and places it onto the discharging rack.

[0011] By adopting the above technical solution, the trolley can lift the empty wire feeding drum and place it on the unloading rack at the same time, and lift the full wire feeding drum and place it in the wire feeding rack at the same time, which further improves the efficiency of loading and unloading, facilitates pre-preparation of materials, reduces the waiting time for loading and unloading, and the automated material changing reduces the labor intensity and the urgency of the work.

[0012] Furthermore, the lifting assembly includes one or more lifting blocks, with the upper part of the lifting blocks being V-shaped and the lower sides of the wire feeding cylinder abutting against the lifting blocks.

[0013] By adopting the above technical solution, the V-shaped lifting block improves its adaptability to wire feeding cylinders of different specifications.

[0014] Furthermore, the movable wheel assembly is connected to a corresponding linear drive cylinder and is driven to slide by the linear drive cylinder.

[0015] By adopting the above technical solution, the linear drive cylinder realizes the automatic sliding adjustment of the movable wheel assembly, further reducing labor intensity.

[0016] Furthermore, the pressure plate lifting assembly includes a lifting cylinder, which is connected between the wire feeding frame and the upper pressure plate.

[0017] By adopting the above technical solution, the lifting cylinder realizes the lifting of the upper pressure plate, providing adaptability to different specifications of wire feeding cylinders in the height direction.

[0018] Furthermore, the pressure rollers are configured as two symmetrical rollers.

[0019] By adopting the above technical solution, the adaptability of wire feeding drums of different specifications is improved, while the forward and backward rolling of the wire feeding drum is restricted, thereby improving the stability of wire feeding.

[0020] Furthermore, the feeding rack is equipped with a positioning block, and a positioning groove is opened in the positioning block, with the side plate of one end of the wire feeding cylinder located in the positioning groove.

[0021] By adopting the above technical solution, the wire feeding cylinder can be moved accurately from the feeding frame to the lower roller assembly, avoiding misalignment.

[0022] In summary, this utility model has the following beneficial effects:

[0023] The two end plates of the wire feeding drum abut against the lower roller assembly, enabling the wire feeding drum to rotate and feed the material. The pressure roller abuts against the upper side plate of the wire feeding drum, improving the stability during wire feeding. Fixed and movable roller assemblies are provided, which, together with the length of the pressure roller, can improve the adaptability to wire feeding drums of different sizes and improve the versatility of the device. The pressure rollers are also provided as two symmetrical ones, which restricts the forward and backward rolling of the wire feeding drum and improves the stability of wire feeding.

[0024] The trolley lifts the empty wire feeding drum and places it on the unloading rack, while simultaneously lifting the full wire feeding drum and placing it on the wire feeding rack. This further improves the efficiency of loading and unloading, avoids the use of a traveling crane, facilitates pre-preparation of materials, and reduces waiting time for loading and unloading.

[0030] A convenient and quick cable laying device, such as Figure 1 and Figure 2As shown, it includes a wire feeding frame 1 and a wire feeding tube 2. The wire feeding frame 1 includes an upper pressure plate 3 and a lower roller assembly 4. The lower roller assembly 4 includes a fixed roller assembly 41 and a movable roller assembly 42. The movable roller assembly 42 slides along the direction close to or away from the fixed roller assembly 41. The side plates at both ends of the wire feeding tube 2 abut against the lower roller assembly 4. Part or all of the lower roller assembly 4 can be driven by a motor to rotate actively to realize wire feeding. It can also be replaced by an independent front wire feeding, which pulls the cable forward between the two upper and lower rollers through multiple rollers or other means.

[0031] In this embodiment, a corresponding linear drive cylinder 43 is connected between the fixed wheel assembly 41 and the movable wheel assembly 42. The movable wheel assembly 42 is driven by the linear drive cylinder 43 to slide relative to the fixed wheel assembly 41. The fixed wheel assembly 41 is also connected to several guide rods, which pass through the movable wheel assembly 42 to guide its sliding. In other embodiments, the movable wheel assembly 42 can also be guided by a moving track below, and the smoothness of sliding can be improved by the rollers below.

[0032] like Figure 1 As shown, the upper pressure plate 3 is connected to the pressure plate lifting assembly, which drives it to move up and down. The pressure plate lifting assembly includes a lifting cylinder 32, which is connected to the top of the wire feeding frame 1 and the lower output end is connected to the upper pressure plate 3. The top of the wire feeding frame 1 is also connected to several guide columns that penetrate the upper pressure plate 3 to achieve guidance. The lifting cylinder 32 can also be replaced by a hydraulic cylinder or a linear module or other structures.

[0033] One or more pressure rollers 31 are connected below the upper pressure plate 3. The pressure rollers 31 abut against the upper side of the side plate of the wire feeding cylinder 2, and the length of the pressure rollers 31 is not less than the maximum distance between the fixed wheel set 41 and the movable wheel set 42, so as to ensure that the pressure rollers abut against the upper side of the side plates at both ends of the wire feeding cylinder 2 of different specifications. In this embodiment, the pressure rollers 31 are set as two symmetrical ones, which abut against the front and rear sides above the side plate of the wire feeding cylinder 2, respectively, so as to realize the forward or backward limit of the wire feeding cylinder.

[0034] like Figure 1 As shown, both the fixed wheel set 41 and the movable wheel set 42 include a pair of abutting wheels (the linear drive cylinders 43 are arranged in pairs accordingly, the abutting wheels are recessed in the middle, and the side plates at both ends of the feeding cylinder 2 are limited in the recess to prevent movement). A passage trolley 5 is provided between the abutting wheels in the middle, and a track is provided below the passage trolley 5 to guide its movement. It can be driven by a motor or pulled by hydraulic cylinders or air cylinders set at the front and rear ends.

[0035] The trolley 5 is equipped with at least one lifting component to lift or lower the wire feeding cylinder 2 from the abutment roller. In this embodiment, there are two lifting components, each being a lifting block 51. The lifting block 51 is lifted by a hydraulic cylinder or electric cylinder or other structure and guided by a guide rod. The upper part of the lifting block 51 is V-shaped, which makes it convenient for the wire feeding cylinders 2 of different specifications to abut against the lifting block 51 on both sides.

[0036] like Figure 2 As shown, the wire feeding frame 1 is provided with a feeding frame 6 and a discharging frame 7 on both sides. Both the feeding frame 6 and the discharging frame 7 include symmetrically arranged placement beams 61. The trolley 5 lifts the wire feeding drum 2 that is full of material on the feeding frame 6 and puts it into the wire feeding frame 1, and lifts the empty wire feeding drum 2 and puts it on the discharging frame 7 (the feeding frame 6 or the discharging frame 7 can also be made longer to accommodate more wire feeding drums 2).

[0037] The feeding rack 6 is equipped with a positioning block 62, and a positioning groove is opened in the positioning block 62. The side plate of one end of the wire feeding tube 2 is located in the positioning groove. After the side plate of the wire feeding tube 2 moves, it is located on the fixed wheel group 41, so that the moving distance of wire feeding tubes 2 of different widths is the same.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present utility model's technical solution.
