Oven sealing cover structure on metal product cleaning equipment
The technical field is as follows:
the invention relates to the technical field of metal product cleaning devices, in particular to a sealing cover structure of an oven on metal product cleaning equipment.
Background art:
there are currently a class of metal products that have a pair of handles on either side of the top and a pair of feet on the bottom, with epoxy glue on the surface, which can be cleaned with acetone according to the prior art. The general cleaning process of the device for cleaning metal products by acetone in the prior art is as follows: the metal product is conveyed into the cleaning box by the conveying mechanism and put down, the cleaning box cleans the metal product by acetone, after cleaning is completed, the metal product is grabbed by the conveying mechanism again, then the metal product is conveyed into the drying mechanism for drying, and finally the metal product is conveyed out of the cleaning device. The device for cleaning the metal product by acetone has the following defects: after the cleaning process is completed, the drying process cannot be performed immediately, and the metal product needs to be transferred by the transfer mechanism, resulting in a reduction in production efficiency. Thus, a cleaning apparatus is proposed in which both cleaning and drying are performed in an oven to improve the cleaning effect, so that it is necessary to remove the cleaning facility from the oven, and the oven is required to be provided with a sealing cover which is believed to be automatically opened and closed.
The invention content is as follows:
the invention aims to overcome the defects in the prior art, and provides a sealing cover structure of an oven on metal product cleaning equipment, wherein the sealing cover adopts a pure mechanical structure, can realize automatic closing and opening, and is convenient, quick and energy-saving.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a sealing cover structure of an oven on metal product cleaning equipment comprises the oven and a water spraying ring seat, wherein the water spraying ring seat is inserted in the oven, a sealing cover is formed at the upper end of the water spraying ring seat and is abutted against the upper end surface of the oven, a plurality of vertical stand columns are inserted and connected on the outer edge of the sealing cover, the lower ends of the stand columns are fixed on the oven, the upper ends of the stand columns are fixed on a top plate, a lifting cylinder is fixed at the center of the upper end surface of the top plate, a piston rod of the lifting cylinder penetrates through the top plate and is fixed on the sealing cover, a circular end cover opposite to the water spraying ring seat is arranged on the oven and consists of a plurality of fan-shaped support plates, an L-shaped support lug is formed at the center of an arc part outside each support plate and is hinged on a T-shaped hinge seat through a T-shaped hinge shaft, a torsion spring is inserted and connected on the, the articulated shaft is inserted and fixed on the support lug.
Preferably, the upright columns are uniformly distributed in an annular shape around the central axis of the water spray ring seat, and at least three upright columns are arranged.
Preferably, the number of the support plates on the circular end cover is at least four, and the diameter of the outer wall of the circular end cover is larger than that of the outer wall of the water spraying ring seat.
Preferably, the stroke of the lifting cylinder is greater than the length of the water spray ring seat.
The invention has the beneficial effects that: the sealing cover structure with a pure mechanical structure can be automatically closed and opened, and is convenient, quick and energy-saving.
Description of the drawings:
FIG. 1 is a schematic view in partial cross-section taken in the direction of the front view of the seal of the present invention when opened;
fig. 2 is a bottom view of the sealing lid of the present invention.
In the figure: 1. an oven; 2. a water spray ring seat; 21. sealing the cover; 3. a column; 4. a top plate; 5. a circular end cap; 51. a support plate; 511. supporting a lug; 6. a hinged seat; 7. hinging a shaft; 8. a torsion spring; 11. and a lifting cylinder.
The specific implementation mode is as follows:
example (b): referring to fig. 1 and 2, an oven sealing cover structure on a metal product cleaning device comprises an oven 1 and a water spraying ring seat 2, the water spraying ring seat 2 is inserted in the oven 1, a sealing cover 21 is formed at the upper end of the water spraying ring seat 2, the sealing cover 21 is abutted against the upper end face of the oven 1, a plurality of vertical upright posts 3 are inserted and connected on the outer edge of the sealing cover 21, the lower ends of the upright posts 3 are fixed on the oven 1, the upper ends of the upright posts 3 are fixed on a top plate 4, a lifting cylinder 11 is fixed at the center of the upper end face of the top plate 4, a piston rod of the lifting cylinder 11 penetrates through the top plate 4 and is fixed on the sealing cover 21, a circular end cover 5 opposite to the water spraying ring seat 2 is arranged on the oven 1, the circular end cover 5 is composed of a plurality of fan-shaped support plates 51, an L-shaped support lug 511 is formed at the center of the arc part outside the support plate 51, articulated shaft 7 on the plug bush have a torsional spring 8, the tip at articulated shaft 7 is fixed to the one end of torsional spring 8, on the fixed hinge seat 6 of the other end of torsional spring 8, articulated shaft 7 is pegged graft and is fixed on journal stirrup 511.
Preferably, the upright columns 3 are uniformly distributed in an annular shape around the central axis of the water spray ring seat 2, and at least three upright columns 3 are arranged.
Preferably, the number of the support plates 51 on the circular end cover 5 is at least four, and the diameter of the outer wall of the circular end cover 5 is larger than that of the outer wall of the water spray ring seat 2.
Preferably, the stroke of the lifting cylinder 11 is greater than the length of the water spray ring seat 2.
The working principle is as follows: the invention relates to a sealing cover structure of an oven on metal product cleaning equipment, wherein when a lifting cylinder 11 drives a water spray ring seat 2 to enter an oven 1, the water spray ring seat 2 can prop open a circular end cover 5, so that support plates 51 are separated in a dispersed manner, and when the water spray ring seat 2 is separated from the oven 1, the support plates 51 can be turned over together under the action of a torsion spring 8 to form the circular end cover 5, so that the inlet of the water spray ring seat 2 entering the oven 1 is sealed.
The examples are intended to illustrate the invention, but not to limit it. The described embodiments may be modified by those skilled in the art without departing from the spirit and scope of the present invention, and therefore, the scope of the appended claims should be accorded the full scope of the invention as set forth in the appended claims.
