Degree and service life so that roller substantially increases intensity again while meeting size and requiring.
Description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the schematic diagram of door coil assembly position in a kind of plastic circular loom of the utility model；
Fig. 2 is the schematic diagram of roller in embodiment illustrated in fig. 1.
Specific implementation mode
The utility model provides a kind of plastic circular loom, including rack and door coil assembly, shuttle set on rack, such as Fig. 1
Shown, door coil assembly includes visit circle 1 and Xiamen circle 2, visits and is equipped with drum assembly, drum assembly edge between circle 1 and Xiamen circle 2
Being circumferentially provided with for door coil assembly is multiple, and all drum assemblies form the track run for shuttle 9, and drum assembly includes one
Mandrel 3 and a roller 4 being sleeved on mandrel 3, roller 4 include cylinder 41 and colloid 42, visit circle 1 and Xiamen circle 2 passes through cylinder
The support of body 41 keeps spacing, is seen in conjunction with Fig. 2, and cylinder 41 includes interconnecting piece 411, strengthening portion 412 and support portion 413, interconnecting piece
411 are connected to the both ends of support portion 413 by strengthening portion 412, and interconnecting piece 411 is connect by bearing 5 with mandrel 3, and colloid 42 is set
In the periphery of support portion 413, shuttle 9 is contacted with colloid 42, and the outer diameter of interconnecting piece 411 is D1, internal diameter d1, strengthening portion 412
Outer diameter is D2, internal diameter d2, and the outer diameter of support portion 413 is D3, internal diameter d3, D1 >=D2 ＞ D3, d1 ＞ d2 >=D3 and support portion
413 thickness B1 is more than the thickness B2 of interconnecting piece 411 so that the intensity of strengthening portion 412 is reinforced.
Since a roller 4 is only arranged, 4 quantity of roller is few, reduce assembly intensity, be conducive to improve efficiency of assembling, from cut
Seen on face, interconnecting piece 411, strengthening portion 412 and support portion 413 form step structure, shuttle 9 impact the active force of roller 4 by
After colloid 42 absorbs major part, remainder by support portion 413 be transferred to successively strengthening portion 412, interconnecting piece 411, bearing 5,
Mandrel 3 and door coil assembly, the thickness of support portion 413 is more than the thickness of interconnecting piece 411, in the ability for bearing active force at the first time
It is stronger, and the thickness of strengthening portion 412 is maximum, not only radial support ability is improved, but also axial bearing capacity is also carried
Height greatly improves the bearing capacity of cylinder 41, effectively improves the service life of roller 4, and not only shuttle 9 is run more stable, simultaneously
But also roller 4 supports the stability of door coil assembly and reliability to be improved.Since the outer diameter of support portion can become smaller,
The space having more can be used for increasing the thickness of colloid, it is strong to increase it after the pitch requirements between meeting two neighboring roller
Degree and service life so that roller substantially increases intensity again while meeting size and requiring.
Cylinder 41 generally may be used the high material of intensity and be made, such as steel, and colloid 42 then uses casting mode and cylinder
Body 41 connects, and the material that polyurethane equal strength is high, wearability is good generally may be used, due to cylinder 41 and colloid 42 be two kinds not
Same material, to improve the reliability that colloid 42 is connect with cylinder 41, support portion 413 forms positioning colloid 42 with strengthening portion 412
Groove 414.In view of space is limited, to avoid influencing organizine conveying, while ensuring the intensity of support portion 413, groove 414
It is 2mm that depth De, which is not more than in 5mm, such as the present embodiment,.
Strengthening portion 412 forms the positioning surface 415 of positioning bearing towards the surface of interconnecting piece 411.Strengthening portion 412 directly with
Bearing 5 contacts, and in addition to axially position bearing 5, impact force can also be directly passed to bearing 5, reduces what interconnecting piece 411 was subject to
Impact, interconnecting piece 411 can be not subject to axial force, and the intensity requirement of interconnecting piece 411 can be reduced suitably, therefore connect
The thickness in portion 411 can be reduced suitably, can reduce the outer diameter of interconnecting piece 411, the space between two neighboring roller 4 in turn
Increase is conducive to organizine conveying, can also increase the internal diameter of interconnecting piece, and the internal diameter of interconnecting piece is sufficiently large, size can be used larger
Bearing, improve the intensity of bearing, the bearing capacity of drum assembly can be improved.
In the present embodiment, in order to ensure the contact area of colloid 42 and shuttle 9, the stability that shuttle 9 is run is improved, branch
The length L of support part 413 is not less than 40mm.Certainly, since the spacing visited between circle 1 and Xiamen circle 2 is generally in 120mm or so,
So the length of support portion 413 also can not be long, 65mm is not exceeded generally.But for the utility model, this size
It is required that and it is nisi, you can to determine the length of support portion according to actual needs.
To keep the spacing for enclosing 1 with Xiamen circle 2 of visiting, upper positioning sleeve can be equipped with positioned at the top of roller 4 on mandrel 3
31, the lower section that roller 4 is located on mandrel 3 is equipped with lower positioning sleeve 32, and circle 1 of visiting is butted on positioning sleeve 31, and upper positioning sleeve 31 resists
The bearing 5 of the bearing 5 of 41 upper end of cylinder, 41 upper end of cylinder is butted on strengthening portion 412, and strengthening portion 412 is butted on the axis of 41 lower end of cylinder
5 are held, the bearing 5 of 41 lower end of cylinder resists lower positioning sleeve 32, and lower positioning sleeve 32 is butted on Xiamen circle 2.
The upper end of mandrel 3 passes through circle 1 of visiting, lower end that Xiamen is passed through to enclose 2, and the both ends of mandrel 3 are locked by nut 6.Screw thread
Connection has good self-lock ability, while facilitating assembly and disassembly again.
To improve the service life of bearing 5, it can be equipped with upper dustproof cover 43 in the upper end of cylinder 41, upper dustproof cover 43 covers on
