Description

Technical Field

[0001] This utility model belongs to the technical field of wire processing equipment, and in particular relates to a lifting multi-station pipe feeding mechanism. Background Technology

[0002] Electrical wires are conductors that transmit electrical energy. After the wires are manufactured, a sleeving machine can be used to sleeve flexible tubes made of materials such as PVC and TPU on the ends of the wires. Workers can then clearly identify the type and model of the wires by labeling them, thus avoiding confusion during the packaging and use of the wires.

[0003] The existing tubing machine mainly consists of a tubing feeding mechanism and an assembly mechanism. The tubing feeding mechanism is used to transport the entire tubing to the assembly mechanism. The cutting part built into the assembly mechanism cuts the tubing into short strips, which are then fitted onto the wire to complete the assembly, making it relatively convenient to use.

[0004] However, most existing pipe feeding mechanisms can only deliver hoses of a single diameter, resulting in poor overall applicability of the equipment. Although some pipe feeding mechanisms have multiple stations to place hoses of different diameters and can complete the delivery of hoses of the corresponding diameter by switching stations, they are often complex in structure, have high manufacturing costs, and require a large installation space. Therefore, it is necessary to design a lifting multi-station pipe feeding mechanism to solve this problem. Utility Model Content

Detailed Implementation

[0038] 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 a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. It is understood that the accompanying drawings are provided for reference and illustration only and are not intended to limit the present utility model. The connection relationships shown in the drawings are only for clear description and do not limit the connection method.

[0039] See appendix Figure 1 -Appendix Figure 8A lifting multi-station pipe feeding mechanism includes a base 1, a feeding section 2, a carrier 3, and a lifting section 4. The feeding section 2 is mounted on the base 1 and is used to feed a flexible hose R. The carrier 3 is provided with a placement plate 31 and a guide plate 32. The placement plate 31 has a plurality of vertically arranged workstation holes 310, and each workstation hole 310 can accommodate at least one type of flexible hose R. The guide plate 32 has a plurality of vertically arranged guide holes 320, which are aligned one-to-one with the workstation holes 310 and can be adapted to guide the corresponding flexible hose R to the feeding section 2. The lifting section 4 is mounted on the base 1 and drivenly connected to the carrier 3 to drive the carrier 3 to move in the vertical direction so that the plurality of guide holes 320 are aligned one-to-one with the feeding section 2.

[0040] Specifically, before use, workers can preset and adjust multiple workstation holes 310 to correspond to the insertion and placement of hoses R of different diameters and models according to actual needs.

[0041] In use, when any station hole 310 and the corresponding guide hole 320 are aligned with the feeding part 2, the hose R of the current pipe diameter model can be accurately guided to the feeding part 2, and the feeding part 2 will transport the hose R to the next process for assembly. When the carrier 3 is driven up and down by the lifting part 4, the station hole 310 and guide hole 320 with hoses R of other different pipe diameter models will be aligned with the feeding part 2 one by one, thereby completing the station switching, so that the feeding part 2 can transport hoses R of other pipe diameter models to the next process for assembly.

[0042] In summary, this utility model improves the applicability by providing multiple workstation holes 310 on the placement plate 31 of the carrier 3 for passing through and placing hoses R of various diameters, and by providing multiple guide holes 320 on the guide plate 32 of the carrier 3 for passing through and guiding hoses R of corresponding diameters, thus accurately guiding the hoses R to the feeding section 2. Furthermore, by installing a lifting section 4 on the base 1 to control the vertical movement of the carrier 3 to complete workstation switching, the ease of operation is improved. Therefore, compared with the prior art, this pipe feeding mechanism can not only adapt to conveying hoses R of various diameters, but also has a simple structure and low manufacturing cost. On the other hand, because the multiple workstation holes 310 and multiple guide holes 320 are vertically arrayed, the overall structure is more compact, effectively reducing the planar volume and the space occupied during installation, while also shortening the time required for workstation switching and improving work efficiency.

[0043] See appendix Figure 3 -Appendix Figure 9Currently, there are various types of feeding units 2 on the market, and most of them are based on conventional technology. Therefore, this utility model does not impose any restrictions on them. For ease of understanding, in this embodiment, the feeding unit 2 includes a support column 21, a swing arm 22, a tube wheel 23, a first driving member 24, and a second driving member 25. The support column 21 is vertically mounted on the base 1 and rotatably connected to the swing arm 22. The tube wheel 23 is rotatably mounted on the first end of the swing arm 22 and located beside the guide plate 32. The first driving member 24 is mounted on the base 1 and rotatably connected to the second driving member 25 of the swing arm 22. The first drive unit 24 is connected to the base 1 to drive the swing arm 22 to swing or stop, thereby causing the tube wheel 23 to move away from or towards the guide hole 320; the second drive unit 25 is mounted on the base 1 and driven to drive the tube wheel 23 to rotate; wherein, the feeding part 2 is provided with two sets and symmetrically arranged on the left and right sides of the guide plate 32, and the two first drive units 24 can synchronously drive the two swing arms 22 to swing, so that the two tube wheels 23 synchronously abut or release the hose R, and either set of feeding parts 2 may not be provided with the second drive unit 25.

[0044] Specifically, under normal circumstances, the second drive unit 25 is in the closed state, and the two first drive units 24 drive the two swing arms 22 to swing synchronously, causing the two tubular wheels 23 to expand towards each other and move away from the guide plate 32. When it is necessary to transport the hose R, the lifting unit 4 controls the carrier 3 to move vertically, so that the hose R, which passes through the sequential work station hole 310 and guide hole 320, smoothly enters the middle of the two tubular wheels 23. Then, the two first drive units 24 are activated to drive the two swing arms 22 to swing synchronously, causing the two tubular wheels 23 to move closer together and abut against the hose R. After the two swing arms 22 stop under the control of the two first drive components 24, the second drive component 25 is activated to drive the corresponding tube wheel 23 to rotate, which can move the hose R to the next process. After the hose R of the current diameter type is delivered, if it is necessary to switch the station to deliver hose R of other diameter types, the two swing arms 22 need to be driven synchronously by the first drive component 24 again so that the two tube wheels 23 expand towards each other and move away from the guide plate 32, so as to avoid the feeding part 2 blocking the hose R from entering between the two tube wheels 23 during the switching of the station.

[0045] If one second driving member 25 is provided, one tube wheel 23 can be driven to rotate to drive the hose R, while the other tube wheel 23 is driven by the moving hose R; if two second driving members 25 are provided, the two tube wheels 23 can be driven to rotate in opposite directions simultaneously, thereby synchronously conveying the hose R; the manufacturer can determine the number of second driving members 25 according to actual needs, and this embodiment does not impose any restrictions on this.

[0046] In summary, compared with the conventional feeding section 2 in the prior art, the above structural design can ensure that the feeding section 2 can be smoothly used with the station hole 310 and guide hole 320 of the carrier 3, avoiding the feeding section 2 from hindering station switching, thereby effectively improving work efficiency.

[0047] See appendix Figure 6 -Appendix Figure 9 The second end of the swing arm 22 is rotatably mounted with a roller 220. The first driving component 24 includes a first cylinder 241, a first connecting rod 242 and a first slider 243. The first slider 243 is slidably mounted on the support column 21 and fixed to the first connecting rod 242. The first slider 243 is also provided with a wheel groove 2430 that rotatably cooperates with the roller 220. The first cylinder 241 is mounted on the base 1 and the telescopic end of the first cylinder 241 is fixed to the first connecting rod 242.

[0048] Specifically, in use, by controlling the extension or retraction of the first cylinder 241, the roller 220 and the wheel groove 2430 can be driven to rotate relative to each other, thereby driving the first slider 243 to move back and forth, which in turn causes the swing arm 22 to swing. When the extension or retraction of the first cylinder 241 stops, the first slider 243 stops moving, causing the swing arm 22 to stop.

[0049] It should be noted that, in addition to the above-mentioned structure, the first driving member 24 that can drive the swing arm 22 to swing is of various types, so this utility model does not limit it.

[0050] See appendix Figure 6 -Appendix Figure 9 The support column 21 has a shaft 211 rotatably mounted inside. The swing arm 22 is rotatably connected to the shaft 211, and the first end of the swing arm 22 is rotatably mounted with a rotating rod 221 fixed to the pulley 23, so that the swing arm 22 is rotatably mounted on the support column 21. The second driving component 25 includes a first motor 251, a belt 252, a pulley 253, a main gear 254, and a secondary gear 255. The main gear 254 and the secondary gear 255 are both movably arranged inside the swing arm 22 and mesh with each other. The main gear 254 is coaxially fixed to the first end of the shaft 211, and the secondary gear 255 is coaxially fixed to the rotating rod 221. The pulley 253 is coaxially fixed to the tail end of the shaft 211. The first motor 251 is mounted on the base 1, and the output end of the first motor 251 is connected to the pulley 253 through the belt 252.

[0051] Specifically, when the two tube wheels 23 synchronously contact the hose R, the first motor 251 is started. The output end of the first motor 251 drives the shaft 211 to rotate through the belt 252 and pulley 253, which in turn drives the main gear 254 to rotate and drives the secondary gear 255 to rotate. The secondary gear 255 then drives the tube wheels 23 to rotate synchronously through the rotating rod 221 to deliver the hose R.

[0052] When the first drive member 24 drives the two swing arms 22 to swing away from the guide plate 32, the main gear 254 and the secondary gear 255 will move with the swing arms 22. During this process, the secondary gear 255 may rotate slightly, which will drive the main gear 254 and the shaft 211. Therefore, before starting the first drive member 24, the first motor 251 must be turned off and the output end of the first motor 251 must be ensured to rotate normally so that the shaft 211 has the corresponding amount of rotation, and the main gear 254 and the secondary gear 255 will not be damaged by rigid collision.

[0053] It should be noted that, in addition to the above-mentioned structure, there are various types of structures for the second driving member 25 that can drive the tube wheel 23 to rotate, so this utility model does not impose any restrictions on it.

[0054] See appendix Figure 9 The outer circumferential wall of the tube wheel 23 is provided with anti-slip texture 230; the design of anti-slip texture 230 can increase the friction between the tube wheel 23 and the hose R, reduce the risk of hose R detachment, and ensure that the two tube wheels 23 can deliver hose R more smoothly.

[0055] See appendix Figure 1 -Appendix Figure 7 and attached Figure 10 The lifting unit 4 includes a second motor 41, a screw 42, a screw block 43, and a support rod 44. The support rod 44 is vertically and slidably mounted on the base 1 and fixed to the carrier 3. The screw block 43 is fixed to the support rod 44. The screw 42 is vertically and rotatably mounted on the base 1 and threadedly connected to the screw block 43. The second motor 41 is mounted on the base 1, and the output end of the second motor 41 is coaxially fixed to the screw 42. The second motor 41 is started to drive the screw 42 to rotate, thereby driving the screw block 43 and the support rod 44 to move in the vertical direction, thereby causing the carrier 3 to move in the vertical direction to complete the workstation switching.

[0056] It should be noted that, in addition to the above-mentioned structure, there are various types of lifting parts 4 that can drive the vehicle 3 to move up and down and have a travel range, so this utility model does not limit them.

[0057] See appendix Figure 1 -Appendix Figure 7 and attached Figure 11 -Appendix Figure 12Manufacturers can set multiple hole diameters for multiple workstation holes 310 to adapt to and fix hoses R of different diameters. However, this reduces the adaptability of a single workstation hole 310 and weakens the ability to restrict hose R, resulting in the possibility of hose R falling off during workstation switching. To solve this problem, this utility model also includes an adjustment part 5. The placement plate 31 has multiple vertically arranged through grooves 311, which are connected one-to-one with multiple workstation holes 310. A fixed pad 312 is provided inside the through groove 311 on the left side of the workstation hole 310, and a slidable clamping block 313 is provided inside the through groove 311 on the right side of the workstation hole 310. The adjustment part 5 is installed on the base 1 and drivenly connected to the clamping block 313 to drive the clamping block 313 to move along the through groove 311 away from or closer to the pad 312, thereby clamping or loosening the hose R passing through the workstation hole 310.

[0058] Specifically, under normal circumstances, the adjusting part 5 drives the clamping block 313 to move inward along the through groove 311 and approach the pad block 312 to clamp and fix the hose R located in the work station hole 310 and placed between the pad block 312 and the clamping block 313, so as to prevent the hose R from falling off during the work station switching process. When the hose R corresponds to the feeding part 2, if it is necessary to transport the hose R, the adjusting part 5 drives the clamping block 313 to move outward along the through groove 311 away from the pad block 312, thereby releasing the restriction on the hose R. At this time, the hose R can be moved into the feeding part 2 and transported by the feeding part 2 to the next process. Similarly, if it is necessary to place a new hose R, the adjusting part 5 also needs to drive the clamping block 313 to move outward along the through groove 311 away from the pad block 312 to make room for placement in the work station hole 310.

[0059] It should be noted that the specifications of the pad 312 and clamp 313 are adjustable. Workers can install the corresponding specifications of pad 312 and clamp 313 in each work station hole 310 according to their needs, so that the work station hole 310 can better fit the hose R of different diameters and models. The pad 312 can be made of materials such as rubber and silicone to give it a certain deformation and recovery ability, ensuring that it can stably fit the hose R and reduce the possibility of damage to the hose R.

[0060] See appendix Figure 1 -Appendix Figure 7 and attached Figure 11 -Appendix Figure 14The base 1 is also provided with a column 11, and the shelf 31 is also provided with a vertical array of multiple movable grooves 314, which are connected one by one to multiple through grooves 311. The clamping block 313 is provided with a stop 3130 that passes through the movable groove 314 to the outside on one end away from the pad block 312. The adjusting part 5 includes an elastic element 51, a second cylinder 52, a second connecting rod 53, a second slider 54 and a hook 55. Multiple elastic elements 51 are provided and are arranged one by one in multiple movable grooves 314, and the two ends of the elastic elements 51 respectively abut against the inner wall of the clamping block 313 and the movable groove 314. The second slider 54 is slidably mounted on the column 11 and fixed to the hook 55, and the second slider 54 is also provided with a slot 541 for a built-in round rod 542. The second connecting rod 53 The first end is inserted into the slot 541 and has a notch 531 that rotates with the round rod 542. The middle part of the second connecting rod 53 is hinged to the column 11. The second cylinder 52 is oscillatingly mounted on the base 1, and the telescopic end of the second cylinder 52 is hinged to the tail end of the second connecting rod 53. The elastic member 51 can drive the clamping block 313 to move inward along the through groove 311 and abut against the pad block 312. The lifting part 4 can drive the carrier 3 to move in the vertical direction so that the abutments 3130 of the multiple clamping blocks 313 are aligned with the hook head 55 one by one. The second cylinder 52 can drive the second slider 54 and the hook head 55 through the second connecting rod 53. The hook head 55 applies pressure to the abutment 3130 to drive the clamping block 313 to move outward along the through groove 311 away from the pad block 312 and squeeze the elastic member 51.

[0061] Specifically, under normal circumstances, the clamping block 313 moves inward along the through groove 311 and approaches the pad block 312 to clamp the hose R under the elastic tendency of the elastic member 51; when it is necessary to transport the hose R, the telescopic end of the second cylinder 52 is controlled to retract, so as to drive the second slider 54 to move away from the carrier 3 through the second connecting rod 53, thereby driving the hook head 55 to abut the abutment 3130. After the hook head 55 applies pressure to the abutment 3130, it can drive the clamping block 313 to move outward along the through groove 311 away from the pad block 312 to release the restriction on the hose R, so as to facilitate the transport of the hose R. During this process, the outwardly moving clamping block 313 squeezes the elastic member 51 to deform and store energy.

[0062] When a workstation needs to be switched, the telescopic end of the second cylinder 52 is extended to drive the second slider 54 toward the carrier 3 via the second connecting rod 53, thereby causing the hook 55 to disengage from the abutment 3130. During this process, the elastic element 51 releases energy and drives the clamping block 313 to move inward along the through groove 311 and approach the pad block 312 to fix the remaining hose R. Then, the carrier 3 is driven to move vertically via the lifting part 4 so that the remaining hose R to be conveyed aligns with the feeding part 2. At this time, the hook 55 is aligned with the abutment 3130 of the new clamping block 313 again. The worker can repeat the above operation to convey the new hose R to the next process.

[0063] In summary, the design of the elastic element 51 can drive the clamping block 313 and the pad block 312 to clamp the hose R precisely, avoiding excessive compression of the hose R and causing it to break. The design of the hook head 55 to align the abutment 3130 of multiple clamping blocks 313 one by one can effectively save costs while ensuring that the outward movement of multiple clamping blocks 313 can be controlled.

[0064] It should be noted that, in addition to the above-mentioned structure, the structure of the adjusting part 5 that can drive the clamping block 313 to move along the slide groove is diverse, so this utility model does not limit it; among them, the elastic element 51 can be a spring, a rubber column (not shown in the figure) or other components with elasticity and recovery ability, and since there are many related components, this utility model does not limit it either.

[0065] See appendix Figure 1 -Appendix Figure 4 and attached Figure 11 -Appendix Figure 12 The guide plate 32 is horizontally and slidably mounted on the carrier 3. The carrier 3 is also equipped with a third cylinder 33. The telescopic end of the third cylinder 33 is fixed to the guide plate 32 to drive the guide plate 32 away from or closer to the front of the feeding part 2. This design can adjust the positional relationship between the placement plate 31, the guide plate 32 and the feeding part 2, avoid the collapse of the suspended part of the hose R, and improve the conveying stability of the hose R.

[0066] See appendix Figure 11 -Appendix Figure 12 The carrier 3 is also provided with a fixing plate 34 and a guide block 35. The guide block 35 is fixedly connected to the carrier 3. A guide rail 36 that is slidably connected to the guide block 35 is horizontally installed on the guide plate 32. The fixing plate 34 is installed on the guide rail 36 and located on the rear side of the feeding part 2. The fixing plate 34 has a plurality of fixing holes 340 arranged vertically. The plurality of fixing holes 340 are aligned one by one with the plurality of guide holes 320.

[0067] Specifically, the design of the fixing hole 340 on the fixing plate 34 can guide the hose R conveyed by the feeding unit 2, preventing the hose R from collapsing and failing to enter the next process normally, thus further improving the conveying stability of the hose R.

[0068] See appendix Figure 11 -Appendix Figure 12 The workstation hole 310, guide hole 320 and fixing hole 340 are all equipped with hollow wear-resistant pads 6, and the hose R can be threaded through the wear-resistant pads 6; the wear-resistant pads 6 can be made of materials such as silicone and rubber. This design can reduce the wear of the hose R and extend the service life of the hose R.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
