Description

Technical Field

[0001] This utility model relates to the technical field of welding machines, specifically a welding machine for wool sleeve end caps. Background Technology

[0002] Brush tubes have applications in various fields such as wall brushes and cleaning brushes. Generally, brush tube production is relatively simple, resulting in low technical complexity and low profit margins. Brush tubes are also called brush sleeves or brush covers. Figure 1 As shown, as the name suggests, it is a sleeve with hair on the outside. The hair sleeve 1 has an end cap 2 welded to each end. The current operation method is to use a conventional spin welding machine. The hair sleeve 1 with end caps 2 on both ends is placed into the spin welding machine fixture by hand, and then one end is heat-welded. After processing, the hair sleeve 1 is removed by hand, and the hair sleeve 1 is rotated to heat-weld the other end. However, this method has the problems of low work efficiency and the need for manual positioning, which makes the operation inconvenient. Therefore, it needs to be improved. Utility Model Content

[0003] The purpose of this invention is to provide a welding machine for end caps of ferrules to solve the problems of low efficiency and inconvenient operation of existing spin welding machines for end cap welding of ferrules, as mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wool sleeve end cap welding machine, comprising a frame and two spin welding machines. A wool sleeve lifting and conveying mechanism, capable of lifting and horizontally transporting along the frame, is provided on the platform of the frame. The two spin welding machines are located at the front and rear ends of the wool sleeve lifting and conveying mechanism and are used for hot-melt welding of end caps on corresponding ends of the wool sleeves. The wool sleeve lifting and conveying mechanism includes a first cylinder, a connecting plate, a lifting rod, a guide rail, a second cylinder, and three sets of wool sleeve positioning groups. The first cylinder is fixed to the bottom of the platform, and the connecting plate is connected to the piston rod of the first cylinder. A guide rail is provided around the perimeter of the connecting plate. The lifting rods running through the tabletop have a shifting support plate between two adjacent lifting rods. A guide rail is slidably connected to both sides of the two shifting support plates. Three sets of wool sleeve positioning groups are spaced apart between the two guide rails. Each set of wool sleeve positioning groups includes two mirror-arranged fixed support frames. A U-shaped positioning groove is provided above each fixed support frame. The two U-shaped positioning grooves on a set of wool sleeve positioning groups are aligned to form a clamp for placing wool sleeves. A cylinder seat is provided between one end of the two guide rails. A second cylinder is located on the side of the cylinder seat, and the piston rod of the second cylinder passes through the cylinder seat and connects to the side of an adjacent shifting support plate.

[0005] Furthermore, in order to improve work efficiency and reduce manual operation, a wool sleeve conveying mechanism is provided behind the table relative to one of the wool sleeve positioning groups for conveying wool sleeves into the clamp. The output end of the wool sleeve conveying mechanism is provided with an infrared sensor for detecting whether the wool sleeve is in place.

[0006] To further achieve primary positioning of the wool sleeve, the table surface is also provided with four spaced-apart lower positioning seats for the wool sleeve fixture. A second U-shaped positioning groove is provided above the lower positioning seat of the wool sleeve fixture, and the second U-shaped positioning groove can be aligned with the lowered U-shaped positioning groove.

[0007] Furthermore, in order to perform primary positioning of the wool sleeve, a positioning mechanism aligned with the output port of the wool sleeve conveying mechanism is provided in front of the table.

The positioning plate is fixed on the table, the linear guide rod is disposed on the positioning plate, and one end of the linear guide rod is connected to the positioning round head, which moves with the linear guide rod. The positioning round head is used to insert into the end cap at one end of the wool sleeve.

[0008] To further enhance safety, a limiting plate is also included. The limiting plate is located on the platform and at the front end of the sleeve lifting and transmission mechanism. One end of the limiting plate is fixed to the platform by a fixed column, and the other end of the limiting plate is provided with two parallel limiting shafts, which are respectively inserted into the two positioning seats of the positioning plate.

[0009] Furthermore, to achieve clamping and positioning of the wool sleeve during hot melting, a fixed beam is also provided above the platform. The fixed beam is provided with two wool sleeve tooling lifting groups that are respectively aligned with two other wool sleeve positioning groups. Each wool sleeve tooling lifting group includes a double-headed cylinder and a wool sleeve tooling upper positioning seat. The two double-headed cylinders are fixed on both sides of the fixed beam, and a wool sleeve tooling upper positioning seat is connected to the piston rod of each double-headed cylinder. A U-shaped positioning groove is provided below the wool sleeve tooling upper positioning seat. After the U-shaped positioning groove moves down, it can press the wool sleeve into the clamp.

[0025] Example 1

[0026] Please see Figures 2-9 As shown, this embodiment discloses a wool sleeve end cap welding machine, including a frame 3 and two spin welding machines 4. A wool sleeve lifting and conveying mechanism 5 is provided on the platform 301 of the frame 3, capable of lifting and horizontally conveying along the frame 3. The two spin welding machines 4 are located at the front and rear ends of the wool sleeve lifting and conveying mechanism 5 respectively and are used for hot-melt welding of the end caps on the corresponding ends of the wool sleeve 1, facilitating user operation. A control panel 302 is also provided on the platform 301. The wool sleeve lifting and conveying mechanism 5 includes a first cylinder 501, a connecting plate 502, a lifting rod 503, a guide rail 504, a second cylinder 505, and three sets of wool sleeve positioning groups. The first cylinder 501 is fixed to the bottom of the platform 301, and the connecting plate 502 is connected to the piston rod of the first cylinder 501. A [missing information - likely a typo, should be "..."] is provided around the connecting plate 502. A lifting rod 503 penetrates the table surface 301. A shifting support plate 506 is provided between two adjacent lifting rods 503. A guide rail 504 is slidably connected to both sides of the two shifting support plates 506. Three sets of wool sleeve positioning groups are spaced apart between the two guide rails 504. Each set of wool sleeve positioning groups includes two mirror-arranged fixed support frames 507. A U-shaped positioning groove 508 is provided above each fixed support frame 507. The two U-shaped positioning grooves 508 on a set of wool sleeve positioning groups are aligned to form a clamp for placing the wool sleeve 1. A cylinder seat 509 is provided between one end of the two guide rails 504. A second cylinder 505 is provided on the side of the cylinder seat 509. The piston rod of the second cylinder 505 passes through the cylinder seat 509 and is connected to the side of an adjacent shifting support plate 506.

[0027] Furthermore, to improve work efficiency and reduce manual operation, a wool sleeve conveying mechanism 6 is provided behind the table 301 at a position close to one of the wool sleeve positioning groups for conveying wool sleeves 1 into the clamp. The output end of the wool sleeve conveying mechanism 6 is provided with an infrared sensor 23 for detecting whether the wool sleeves 1 are in place. To further achieve automatic feeding and improve work efficiency, a pusher cylinder 20 is provided behind the lower positioning seat 7 of the wool sleeve tooling furthest away from the wool sleeve conveying mechanism 6. The pusher cylinder 20 is fixed on the table 301. The table 301 is also provided with a feeding channel 22 located at the front end of the pusher cylinder 20. The piston rod of the pusher cylinder 20 is provided with a pusher head 21 for pushing the wool sleeves 1 into the feeding channel 22.

[0028] To further achieve primary positioning of the wool sleeve 1, four spaced-apart lower positioning seats 7 for the wool sleeve tooling are also provided on the table 301. A second U-shaped positioning groove 8 is provided above each lower positioning seat 7, and the second U-shaped positioning groove 8 can be aligned with the lowered U-shaped positioning groove 508. A positioning mechanism aligned with the output port of the wool sleeve conveying mechanism 6 is provided in front of the table 301. The positioning mechanism includes a positioning plate 9, a linear guide rod 10, and a positioning round head 11. The positioning plate 9 is fixed on the table 301, and the linear guide rod 10 is disposed on the positioning plate 9. One end of the linear guide rod 10 is connected to a rod that moves with the linear guide rod 10. The positioning round head 11 is used to insert into the end cap at one end of the sleeve 1. The above structure, by adding a lower positioning seat 7 to the sleeve tooling on the original technology, realizes the bottom of the sleeve 1 to limit the position, and further improves the stability of the sleeve when it is placed at each station. At the same time, by setting a positioning mechanism at the corresponding position of the sleeve conveying mechanism 6, the initial position of the sleeve is positioned, which also facilitates the welding accuracy of the spin welding machine 4 later. During operation, when the sleeve conveying mechanism 6 conveys the sleeve 1 to one of the sleeve positioning groups, i.e. the primary position, the positioning round head 11 positions one side of the sleeve 1 to prevent it from falling off, and also serves as the positioning function of the sleeve 1.

[0029] like Figure 9As shown, to further improve safety, a limiting plate 12 is also included. In this embodiment, the safety of the entire device is improved by adding a limiting plate 12 to prevent the wool sleeve 1 from falling out of the frame 1. The limiting plate 12 is located on the table 301 and at the front end of the wool sleeve lifting and transmission mechanism 5. One end of the limiting plate 12 is fixed to the table 301 by a fixed column 14. The other end of the limiting plate 12 is provided with two parallel limiting shafts 13. The two limiting shafts 13 are respectively inserted into the two positioning seats 15 of the positioning plate 9. In order to facilitate the positioning round head 11 and the corresponding spin welding machine 4 head to pass through the limiting plate 12, a corresponding through hole is provided on the limiting plate 12 to facilitate the positioning round head 11 and the corresponding spin welding machine 4 head to pass through.

[0030] Furthermore, to achieve clamping and positioning of the sleeve 1 during hot melting, a fixed beam 16 is also provided above the table 301. Two sleeve tooling lifting groups are provided on the fixed beam 16, each aligned with one of the other two sleeve positioning groups. Each sleeve 1 tooling lifting group includes a double-headed cylinder 17 and a sleeve tooling upper positioning seat 18. The two double-headed cylinders 17 are fixed on both sides of the fixed beam 16, and each double-headed cylinder 17 has a sleeve tooling upper positioning seat 18 connected to its piston rod. Below the sleeve tooling upper positioning seat 18 is... The device has a U-shaped positioning groove 19. After the U-shaped positioning groove 28 moves down, it can press the sleeve 1 into the clamping mouth. The above structure adds a sleeve tooling lifting group to the original technology. In order to ensure that when the spin welding machine 4 on both sides performs end cap welding on the sleeve of the station, the double-head cylinder 17 is driven to work, which drives the positioning seat 18 on the sleeve tooling to move down. The U-shaped positioning groove 28 moves down to press the sleeve 1 into the corresponding clamping mouth below. Then, the spin welding machine 4 is used for welding. This further improves the positioning and clamping effect of the sleeve 1 during welding and further improves the welding accuracy.

[0031] It should also be noted that the spin welding machine 4 is existing technology, and how it performs high-pressure spin welding of the end cap 2 to the sleeve 1 is conventional technology in the field. The sleeve conveying mechanism 6 is also existing conventional technology, so it will not be described in detail.

[0032] The working principle of this structure is as follows: First, the wool sleeve 1, with end caps 2 at both ends, is manually placed on the wool sleeve conveying mechanism 6. Under the action of the wool sleeve conveying mechanism 6, the wool sleeve 1 is conveyed to the output port of the wool sleeve conveying mechanism 6 and enters the clamp of one of the wool sleeve positioning groups near the wool sleeve conveying mechanism 6 (in the initial state, ensure that the furthest wool sleeve positioning group is close to the wool sleeve conveying mechanism 6). Then, the first cylinder 501 is driven to work, lifting the wool sleeve 1 on the wool sleeve positioning group, and the second cylinder 505 is driven to work, conveying the wool sleeve 1 to the second station, that is, the one with the previous... At the station cooperating with the end-spinning welding machine 4, because the three wool sleeve positioning groups are lifted and moved simultaneously during operation, the drive cylinder 501 moves the wool sleeve 1 downwards. At this time, one set of wool sleeve positioning groups aligns with the wool sleeve conveying mechanism 6, and then a wool sleeve 1 is conveyed onto that set of wool sleeve positioning groups. The front end of the wool sleeve at the second station aligns with the spin welding machine 4. At this time, the drive cylinder 501 operates to perform hot-melt welding on the front end of the wool sleeve 1. After welding, the drive cylinder 501 operates to lift the wool sleeve 1, and the drive cylinder 505 operates to convey the welded front end of the wool sleeve 1 to the first station. At the third station, the unwelded bushings on the bushing positioning group are conveyed to the second station. Then, the drive cylinder 501 moves the bushing positioning group downwards. At this time, one bushing positioning group aligns with the bushing conveying mechanism 6. Then, a bushing 1 is conveyed onto that bushing positioning group. Meanwhile, the rear end of the bushing 1 at the third station aligns with the rear spin welding machine 4, and the front end of the bushing 1 at the second station aligns with the spin welding machine 4. The corresponding spin welding machine 4 is driven to perform hot melt welding on the bushing 1. After welding, the drive cylinder 501 is first driven to lift the bushing 1, and then the drive cylinder 505 is driven to lift the bushing 1. The wool sleeve is conveyed to the pusher head 21 and the cylinder 501 is driven to move the wool sleeve 1 down and place it in the lower positioning seat 7 of the wool sleeve tooling on the far right. Then, the pusher cylinder 20 is driven to drive the pusher head 21 to push the finished wool sleeve 1 into the unloading channel 22 to achieve unloading. Then, the above method is repeated to achieve the heat fusion welding of the end caps 2 at both ends of the wool sleeve 1. With this structure, it is not necessary to manually remove the wool sleeve 1 after each welding and manually rotate the wool sleeve, which further improves the work efficiency. Only manual loading is required, which is convenient for users.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
