Summary of the invention
The present invention is directed to prior art problem, provides a kind of seal optimization dress used in the soft box packaging process of cigarette
It sets, is able to maintain that cigarette packet seal forms the improvement structure of carefully and neatly done packing machine seal molding machine.
In order to which the technology and the method that solve the problem above-mentioned use of the invention are as follows:
A kind of improvement structure of packing machine seal molding machine is located at the two sides Yan Bao, includes left forming blocks and right molding
Block is all equipped with pressure apparatus installation passage in the left forming blocks and right forming blocks, is equipped in the pressure apparatus installation passage
Pressure regulation device, the pressure regulation device are made of steel ball, cushion, spring and adjusting screw, and the cushion is located at spring
Both ends, the steel ball and adjusting screw are all abutted via cushion with spring, the adjusting screw and pressure apparatus installation passage spiral shell
Line connection.
Further, a pair of of pressure apparatus installation passage is all equipped in the left forming blocks and right forming blocks.
Further, the adjusting screw is milled screw, is conveniently manually adjusted, and purpose realizes that compressed spring stroke is big
Small adjusting.
Further, the cushion is rubber pad, and purpose has three, and one is to increase steel ball and spring, adjust screw and bullet
The contact area of spring;Secondly protecting spring to extenuate the pressure between spring and steel ball, adjusting screw, increasing its service life;
Thirdly cushion can compress naturally in a certain range when passing through for cigarette packet, protect cigarette packet not easily damaged to a certain degree.
Further, the steel ball is contacted with the seal tree lace position of cigarette packet, steel ball prominent work under natural impaction state
Make face 1.1mm, the two steel ball centre ofs sphere are away from the distance between two tree laces for seal.
Further, the diameter of the steel ball is 4.8mm.
Further, positioning convex platform is all equipped with below the left forming blocks and right forming blocks.
Further, the left forming blocks and right forming blocks are equipped with threaded hole.
The invention has the benefit that by the pressure adjusted between cigarette packet and steel ball realize extruding to cigarette packet seal with
Calibration, optimizes the seal after stickup, it is ensured that the trimness that cigarette packet seal is pasted is not easy to be displaced;Overall structure is simple,
Reliably, easy to repair, long service life can improve the quality and device efficiency of converted products.
Specific embodiment
Below with reference to embodiment, the present invention is described in further detail with attached drawing, but they are not to skill of the present invention
The restriction of art scheme, based on present invention teach that any transformation made, all falls within protection scope of the present invention.
As shown in fig.1, a kind of improvement structure of packing machine seal molding machine, be located at 1 two sides of cigarette packet, include it is left at
Type block 2 and right forming blocks 3 are all equipped with pressure apparatus installation passage 4, the pressure dress in the left forming blocks 2 and right forming blocks 3
It sets and is equipped with pressure regulation device 5 in installation passage 4, the pressure regulation device 5 is by steel ball 6, cushion 7, spring 8 and adjusts screw
9 compositions, the cushion 7 are located at 8 both ends of spring, and the steel ball 6 and adjusting screw 9 are all abutted via cushion 7 with spring 8, described
Screw 9 is adjusted to be threadedly coupled with pressure apparatus installation passage 4.
A pair of of pressure apparatus installation passage 4, the pressure apparatus peace are all equipped in the left forming blocks 2 and right forming blocks 3
Dress channel 4 with the punching of the drill bit of 5mm until working face is got through just, and is put into the steel ball 6 of diameter 4.8mm in hole, from
The spherical surface height that working face exposes is maintained at 1.1 ± 0.1mm, then one section of depth 13mm (wherein right forming blocks depth is processed in hole
For the internal screw thread of 41mm) diameter 6mm, screw 9 is adjusted to install additional.
The spring 8 select outer diameter 4.60mm, work aperture 4.80mm, spring line footpath 0.35mm, working beam diameter 3.60mm,
Drift 15.50mm, spring rate 0.38N/mm, the compression spring for pressing simultaneously height 2.54mm, number of total coils 10.
The adjusting screw 9 is milled screw, is conveniently manually adjusted, and purpose realizes the tune of compressed spring stroke size
Section.
The cushion 7 is rubber pad, and purpose has three, and one is to increase steel ball 6 and spring 8, adjust screw 9 and spring 8
Contact area;Secondly protecting spring 8 to extenuate the pressure between spring 8 and steel ball 6, adjusting screw 9, increasing its service life;
Thirdly cushion 7 can compress naturally in a certain range when passing through for cigarette packet, protect cigarette packet 1 not easily damaged to a certain degree.
The steel ball 6 is contacted with 10 position of seal tree lace of cigarette packet 1, the outburst face under natural impaction state of steel ball 6
1.1mm, the two steel ball centre ofs sphere are away from the distance between two tree laces for seal.
The diameter of the steel ball 6 is 4.8mm.
The left forming blocks 2 and 3 lower section of right forming blocks are all equipped with positioning convex platform 11.
The left forming blocks 2 and right forming blocks 3 are equipped with threaded hole 12, and left forming blocks 2 are determined according to the thickness of cigarette packet 1
Operating distance between right forming blocks 3 determines positioning convex platform according to the position of two positioning square hole (not shown) in equipment
11 design position, size are the size that equipment positions square hole, are connected by threaded hole 12.
1 side of cigarette packet is additionally provided with cigarette packet guide pad 13, and cigarette packet guide pad 13 pastes the cigarette packet after optimization according to seal
Actual range into transfer passage designs, it is therefore intended that the cigarette packet after optimization is pasted in seal and imports transfer passage.
Principles of Regulation and method:
By precession or the adjusting extruding spring 8 of screw 9 is screwed out, so that 8 stroke of spring changes, to adjust steel ball
6 with the pressure of cigarette packet 1, finally adjust according to the actual situation and arrive the molding optimum state of cigarette packet seal.
The invention has the benefit that by the pressure adjusted between cigarette packet and steel ball realize extruding to cigarette packet seal with
Calibration, optimizes the seal after stickup, it is ensured that the trimness that cigarette packet seal is pasted is not easy to be displaced;Overall structure is simple,
Reliably, easy to repair, long service life can improve the quality and device efficiency of converted products.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention, therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
