Description

Technical Field

[0001] The utility model relates to the technical field of membrane tube assembly, in particular to a device for producing and assembling membrane tubes. Background Art

[0002] During the production of flexible filter tube membranes, the filter tube assembly must be placed inside the membrane tube due to the externally mounted positioning filter tube installation method. If the left and right ends are not installed symmetrically during operation, the entire filter tube can become distorted, affecting its performance. Furthermore, during the production of flexible filter tube membranes, the membrane shell is extremely heavy, weighing up to 40-50 kg. During glue injection, clamps are required to secure the membrane shell and position the glue injection. Existing assembly equipment requires moving and securing the membrane shell during the glue injection head assembly, which is not only time-consuming and labor-intensive, but also requires two people to work together, and the assembly results are uncertain.

[0029] During specific implementation, there are two groups of middle position positioning mechanisms 20, and a pair of side positioning rings are a first side positioning ring 30 and a second side positioning ring 40. The first side positioning ring 30 corresponds to the side positioning ring at the end of the injection head 50, and its height can be adjusted. The second side positioning ring 40 is a positioning ring mechanism away from the end of the injection head 50.

[0030] In a specific implementation, the base 10 is arranged along the length direction of the membrane tube assembly 60, and a set of longitudinal beams 11 are respectively provided on the upper surface of both ends of the length direction of the base 10;

[0032] The positioning seats on both sides of the membrane tube include a left membrane tube positioning seat 70 and a right membrane tube positioning seat 80. The left membrane tube positioning seat 70 and the right membrane tube positioning seat 80 each include a bottom support seat 1 and an upper contour support block 2. The upper surface of the contour support block 2 is concave to form an arc groove arranged on the outer surface of the membrane tube assembly 60.

[0033] Each side positioning ring includes a positioning ring mechanism 3 and a fixed bracket 4. The positioning ring mechanism 3 includes an upper convex semicircular ring 5 and a lower convex insertion rod 6. The fixed bracket 4 includes an upper convex insertion groove 7 and a bottom fixing rod 8. The upper convex insertion groove 7 is provided with a vertically arranged waist-shaped hole 71, and the bottom fixing rod 8 is provided with a plurality of locking holes 81.

[0034] In a specific implementation, two sets of middle position positioning mechanisms 20 are arranged at intervals in the middle position in the longitudinal direction of the base 10. When the membrane tube assembly 60 is not placed, the upper semicircular clamp 22 is separated from the lower semicircular connecting clamp 23. When the membrane tube assembly 60 is placed, the upper semicircular clamp 22 and the lower semicircular connecting clamp 23 are fixedly connected and respectively press-fitted on the outer tube annulus of the membrane tube assembly 60.

[0035] The membrane tube left positioning seat 70 and the membrane tube right positioning seat 80 are respectively arranged on both sides of the length direction of the base 10 corresponding to the two sets of middle position positioning mechanisms 20. The side of the bottom support seat 1 on each side is fixed with a side convex assembly longitudinal beam 11;

[0037] During specific implementation, the height position of the positioning ring mechanism 3 of the first side positioning ring 30 is not locked. After the glue injection head 50 is aligned with the die head of the membrane tube assembly 60, the upper glue injection die head component 51 and the lower glue injection die head component 52 in the figure are fixed by the paired die head fixing clamps 90. The height position of the positioning ring mechanism 3 of the first side positioning ring 30 is fixed, and the bottom of the glue injection head 50 is supported on the upper convex semicircular ring 5 of the first side positioning ring 30.

[0038] The height position of the positioning ring mechanism 3 of the second side positioning ring 40 is fixed, and the axial stop ring 101 of the corresponding end die head 100 of the membrane tube assembly 60 is arranged in contact with the upper convex semicircular ring 5, and the outer ring end 102 of the die head 100 of the membrane tube assembly 60 is supported on the upper convex semicircular ring 3 of the second side positioning ring 40; in addition, the right edge of the left membrane head 100 of the membrane tube assembly 60 is in contact with the right edge of the membrane tube left positioning seat 70 for positioning;

[0039] The base 10 includes two longitudinal side beams 12 and a plurality of cross beams 13. The outer ends of the assembly longitudinal beams 11 are supported on the end cross beams 13 through vertical rods 14, which ensures that the assembly of the assembly longitudinal beams 11, the base 10 and the side positioning seats is stable and reliable.

[0040] The lower convex supporting parts 231 of the lower semicircular connecting clamps 23 of the two sets of middle position positioning mechanisms 20 are respectively positioned and embedded in the placement grooves 211 of the bottom positioning clamps 21. The bottom positioning clamps 21 are welded to the bottom crossbeam 13, which allows the clamps to be quickly replaced according to the actual pipe diameter, ensuring the versatility of the entire mechanism.

[0041] The locking hole 81 of the bottom fixing rod 8 is fixed to the corresponding length position of the assembly longitudinal beam 11 by a bolt and nut mechanism, which allows the position of the bottom fixing rod 8 to be fine-tuned according to the length of the membrane tube assembly 60, ensuring reliable support and positioning of the membrane tube assembly 60.

[0042] Its working principle is as follows: the lower semicircular connecting clamps of the clamps are respectively installed on the bottom positioning bases, and then the membrane tube assembly is placed on the membrane tube production and assembly device. At this time, the membrane head at one end of the membrane tube assembly where the glue injection head is not installed is axially positioned by one group of side positioning rings, so that the entire membrane tube assembly is reliably supported and set, and then the filter tube assembly 110 is inserted into the membrane tube assembly 60, and the positioning ring mechanism of the unlocked height is adjusted so that the glue injection head is assembled to one end portion formed by the membrane tube assembly and the filter tube assembly, and then the height of the positioning ring mechanism at this end is adjusted so that the glue injection head is supported on the positioning ring mechanism at the corresponding position, which makes the membrane tube assembly and the filter tube assembly reliably radially positioned, and the assembly of the glue injection head is simple and quick, ensuring the quality of subsequent finished products.
