Specific embodiment
The present invention provides one kind to move back tin equipment, to keep the purpose of the present invention, technical solution and effect clearer, bright
Really, the present invention is described in more detail below.It should be appreciated that specific embodiment described herein is only used to explain this hair
It is bright, it is not intended to limit the present invention.
For ease of description, in the present invention, the front, rear, left and right of molten tin bath are moved back, are with the visual angle of attached drawing for reference, with
The difference of the difference for putting visual angle of molten tin bath or the coordinate system of selection is moved back, the description of technical solution of the present invention can not
Together.
The preferred embodiment provided by the invention for moving back tin equipment is as depicted in figs. 1 and 2, including move back molten tin bath 1, be connected to it is described
It moves back the rotary shaft 2 between molten tin bath front and rear wall and 2 or more (in Fig. 2 for 2) and is fixed on the turntable in the rotary shaft
3；The bottom surface for moving back molten tin bath is the cambered surface 11 with the rotary shaft concentric, preferably semicircle cambered surface；The turntable is described
It is uniformly distributed in rotary shaft with the first gap L 1, and is rotated synchronously with the rotary shaft, the end face of the turntable is provided with several
3 limiting sections are only depicted in limiting section 31(Fig. 1)；Described move back is provided with push rod 4 on the left of molten tin bath, for pushing product 7
Into the limiting section of the turntable；Described move back is provided with pull rod 5 on the right side of molten tin bath, for the limiting section by product from the turntable
Middle pull-out.Wherein, it is normal that push rod, the motion control of pull rod, the rotation of rotary shaft drive turntable and conveyer belt 6, which transport product,
Technological means is advised, inventive content of the invention is not belonging to, does not describe excessively herein.The course of work of this equipment are as follows: described
Push rod often pushes in a product, and turntable correspondingly turns an angle, θ, and θ is just equal to the angle of adjacent limiting section, then draws
Bar pulls out a product；Alternatively, angle, θ of every turn of turntable, the push rod pushes in a product, while the drawing
Bar pulls out a product.It can select to be arranged according to the actual situation.
The of the invention tin equipment occupied ground area that moves back is small, does not need the production line grown very much, entirely moves back tin process and moving back tin
It is completed in slot, and the soaking time in molten tin bath can moved back by controlling the revolving speed of turntable to adjust product, it is easy to operate.
In order to further improve product go to move back molten tin bath bottom when, the sliding friction problem of product and curved bottom can be with
Crawler belt (or conveyer belt) 8 is set in curved bottom, as shown in Figure 1, the crawler belt and the rotary shaft keep rotating synchronously.In this way
It avoids product edge and is worn with the bottom for moving back molten tin bath.
A kind of preferred embodiment of limiting section on turntable of the invention as shown in figure 3, the end face of the turntable along described
The even circumferential of turntable is provided with several sawtooth (Fig. 3 only depicts 3), and the depressed section of the sawtooth forms the limiting section
31, the sawtooth and the turntable integrated molding.Preferably, shown turntable is made of acrylic resin, can further be dropped
Low cost.
In order to improve the production efficiency, the distribution density of limiting section circumferentially needs big as far as possible, and is distributed too closely,
The limiting section intensity of above-mentioned turntable can significantly reduce, and may be not enough to support product weight.For this purpose, the present invention provides one kind to change
Into scheme.The preferred embodiment of the limiting section of improved turntable is as shown in Figure 4, Figure 5, and the end face of the turntable is radially arranged
There are several blind holes 32, the blind hole is distributed along the even circumferential of the turntable, is connected with gag lever post 33 in the blind hole, adjacent
The limiting section 31 is formed between the gag lever post.
To further increase intensity, it is preferred that shown gag lever post is made of carbon fibre material.
It is scratched to prevent product to be limited bar friction when promoting and pulling out, shown gag lever post is preferably cylindric.
A kind of preferable connection type of the gag lever post and the turntable is as shown in Figure 6: in one end of the gag lever post
Screw thread 331 is set, and the gag lever post is connected through a screw thread with the blind hole.
The connection type of above-mentioned turntable and gag lever post may have the case where gag lever post loosening, and therefore, the present invention also mentions
Another more preferably connection type is supplied, as shown in fig. 7, one end of the gag lever post is provided with 2 or more perpendicular to the limit
First threaded hole 332 of the axis of position bar, is provided with and first threaded hole corresponding second in the disk of the turntable
Threaded hole 34, as shown in figure 4, first threaded hole and second threaded hole are just after the gag lever post is inserted into the blind hole
It is right, first threaded hole and the second threaded hole are connected using screw, so that the gag lever post to be fixed on to the end of the turntable
On face.Such connection type reliability is higher.
Preferably, the turntable is set as 3 or more, and limiting section has preferable load-bearing capacity.It specifically can be according to product
Weight the quantity of turntable is adjusted flexibly.
When turntable is set as 3 or more, it is preferred that there are two pawl for the push rod setting.Preferably, the pull rod is set
Pulling claw there are two setting, as shown in Figure 8.It can guarantee in this way and keep motion stabilization when product is promoted, pulled out, prevent from generating in horizontal plane
Rotation.
In conclusion move back tin equipment the present invention provides one kind, the of the invention tin equipment occupied ground area that moves back is small, is not required to
