Detailed Description

The utility model provides a safe type pile bucket blow molding equipment. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.

The safety type stacking barrel blow molding device comprises an extruding unit 2 for extruding a tubular blank 1, a blow molding unit 3 arranged at the bottom of the extruding unit 2, and stacking barrel opening and closing dies 4 which are respectively arranged at two sides of the blow molding unit 3 and have clamping strokes, as shown in fig. 1 to 3.

The extrusion unit 2 extrudes the tubular blank 1, the stacking barrel opening and closing die 4 clamps and loads the tubular blank 1 in the stacking barrel, and the blow molding unit 3 completes the matching after the stacking barrel opening and closing die 4 is clamped, so as to perform blow molding operation.

The blow molding equipment of present case is to bung hole non-pile bucket placed in the middle, needs the design of blow molding unit 3 erroneous tendency one side promptly, and 1 free end of the tubular material embryo of crowded material unit 2 produces deformation easily in extrusion process, hardly freely cup joints on the blow molding unit 3 of erroneous tendency design, consequently needs the manual work to assist the operation of cup jointing, has the potential safety hazard.

In the scheme, the blow molding unit 3 comprises a slide rail 5 which is perpendicular to the clamping stroke direction of the stacking barrel opening and closing mold 4, and a blow molding nozzle 6 and a slide bar 7 which are arranged on the slide rail 5 in a sliding manner.

The blow molding nozzle 6 and the slide bar 7 are provided with material receiving stations which are attached to each other and receive the tubular parison 1, the material receiving stations are shown in fig. 1, the blow molding nozzle 6 and the slide bar 7 are further provided with blow molding operation stations which are separated from each other until the blow molding nozzle 6 is matched with the stacking barrel opening and closing mold 4, and the blow molding operation stations are shown in fig. 2.

Specifically, during the process of extruding the material by the extruding unit 2, the tubular material blank 1 will extend downwards, and the bottom port of the tubular material blank 1 often generates gathering and shrinking deformation, in this case, the blow nozzle 6 and the slide bar 7 gather at the bottom of the axial lead of the extruding unit 2 through sliding displacement, and even if the gathering and shrinking of the bottom port of the tubular material blank 1 becomes smaller, the bottom port can still be automatically sleeved on the blow nozzle 6 and the slide bar 7.

After the sleeving operation is completed, the blow molding nozzle 6 and the slide rod 7 move away from each other, the blow molding nozzle 6 is shifted to a station which is in clamping fit with the stacking barrel opening and closing mold 4, and meanwhile, the blow molding nozzle 6 and the slide rod 7 open the bottom end opening of the tubular blank 1 to assist in the blow molding operation of the stacking barrel.

In a preferred embodiment, a gap 8 is left between the top of the sliding rod 7 and the stacking barrel opening and closing die 4. Namely, an avoiding groove aiming at the slide rod 7 is not required to be additionally arranged on the stacking barrel opening and closing die 4.

Since the air supply hose of the blow nozzle 6 is generally provided at the bottom, the slide rail 5 is selected to have a double parallel-axis slide rail structure for facilitating the selection of the mounting of the conventional blow nozzle 6. The air supply hose can be connected to the blow nozzle 6 through the spacing of the two parallel axes.

In addition, the slide rail structure with the double parallel shafts also facilitates the arrangement of the driving source, in a specific embodiment, the driving source of the blow nozzle 6 can be arranged on the carrier seat of the double parallel shafts, the telescopic driving end of the driving source can perform telescopic operation for driving the blow nozzle 6 to displace along the interval of the double parallel shafts, and the driving source of the slide bar 7 can also adopt the same design.

In one embodiment, the discharge side 41 of the opening and closing mold 4 of the stacking bucket is provided with a monitoring sensor 9, and the monitoring sensor 9 is in communication connection with the driving source of the opening and closing mold 4 of the stacking bucket. More specifically, the monitoring sensor 9 is an infrared radio frequency sensor.

Specifically speaking, when the tubular blank 1 is sleeved in an auxiliary manner, the body of an operator can be inserted from the discharging side 41, so that the operator can avoid entering the stacking barrel opening and closing die 4 by mistake, the monitoring sensor 9 is adopted for monitoring operation, and the operation safety is greatly improved.

Can discover through the above description, the utility model discloses safe type pile bucket blow molding equipment through the stroke design of blowing nozzle and slide bar, easily realizes accepting the tubulose material embryo with automizing, need not the manual work and explore in the pile bucket opens and shuts the mould and assist and cup joint the operation, improved the security. Still add the control sensor at the discharge end of pile barrel open and shut mould, further prevent that the operation personnel from exploring in the pile barrel open and shut mould stroke region, possess high operation completeness. The overall design is simple, the realization is easy, and the potential safety hazard of the traditional semi-automatic blow molding equipment is eliminated.

The above technical solutions of the present invention have been fully described, and it should be noted that the present invention is not limited by the above description, and all technical solutions formed by equivalent transformation or equivalent transformation adopted by the spirit of the present invention in the aspects of structure, method or function by those of ordinary skill in the art all fall within the protection scope of the present invention.
