Technical Field
The invention relates to a bottle blowing machine, in particular to an auxiliary blank inserting device.
Background
When a bottle blowing machine blows a bottle, a bottle blank is heated to a certain temperature through a heating machine and then is sent into a mold for blowing through a manipulator, the first step of heating is to correctly insert the bottle blank into a heating mandrel, the bottle blank is carried by the heating mandrel to rotate and heat in the heating machine, whether the inserted blank is correct or not directly influences the stability of the equipment, the bottle blank is often skewed, the inserted blank is not in place, a blank feeding disc is used for clamping the blank and the like due to the fact that the bottle blank is correctly inserted in the heating mandrel in a traditional mode, once the skewed blank and the blank which is not inserted in place enter the heating machine, the bottle blank is very easy to fall off in a heating furnace under the condition of autorotation of the mandrel, a heating lamp tube is damaged, and the equipment is.
As shown in fig. 1-2, the bottle preform feeding device in the prior art includes a preform feeding tray 1 'and a protection plate 2', and a bottle preform 3 'moves to a preform inserting point under the combined action of the preform feeding tray 1' and the protection plate 2 'for preform inserting, and then is conveyed out under the action of a preform discharging tray 4'. As can be seen from the cross-sectional view of fig. 2, when the bottle preform 3 'is between the preform feeding tray 1' and the protection plate 2 ', the support ring 31' on the bottle preform 3 'is supported on the upper surfaces of the preform feeding tray 1' and the protection plate 2 ', and there is no fit relationship between the anti-theft ring 32' of the bottle preform 3 'and the preform feeding tray 1' and the protection plate 2 ', so that the support is not stable enough against the support ring 31', the bottle preform is prone to be skewed, and in addition, a problem of machine jam may occur once the
Application No. CN201420425131.X discloses a bottle base loading and unloading device of bottle blowing machine to specifically disclose: a left feeding guide plate and a right feeding guide plate are arranged on the upper stream of the bottle pushing blank plate on the rack, and a bottle feeding channel is formed by a gap between the left feeding guide plate and the right feeding guide plate. As can be seen from the text and the accompanying description of the above application, the left feeding guide plate and the right feeding guide plate are both located below the bottle mouth of the bottle blank, so that they only play a role in guiding flow, and cannot prevent the bottle blank from being skewed and inserted in place.
Disclosure of Invention
The invention provides an auxiliary blank inserting device, which aims to solve the technical problem that blank inserting is not in place due to the fact that a bottle blank is inclined in the prior art. The technical scheme of the invention is as follows:
the auxiliary blank inserting device comprises an inner protective ring arranged on a blank feeding disc and an outer protective ring arranged on a protective plate, wherein the inner protective ring and the outer protective ring are positioned on two sides of a blank opening of a bottle blank, and the shape of the inner side face, facing the blank opening, of the inner protective ring and the outer protective ring is matched with the blank opening. Through setting up interior protective shroud and outer protective shroud, prevent that the bottle base is crooked, guarantee standing vertically of bottle base, improve the accuracy of follow-up base of inserting.
Further, interior retainer is the ring form, interior retainer includes fixed part and guard portion, the fixed part with advance base dish fixed connection, the guard portion is located between fixed part and the bottle base mouth.
Further, the protective part is higher than the fixing part, and the upper surface of the protective part is slightly lower than the upper surface of the bottle blank opening.
Furthermore, the side surface of the protection part facing the bottle blank opening is provided with an inner side groove.
Furthermore, the number of the inner side grooves is two, and the two inner side grooves correspond to the anti-theft ring and the support ring on the bottle blank respectively.
Further, the inner convex part between the two inner side grooves protrudes out of the side face of the protection part facing the bottle blank opening.
Further, the outer retainer is arc-shaped, and the upper surface of the outer retainer is slightly lower than the upper surface of the bottle blank opening.
Furthermore, the side surface of the outer retainer facing the bottle blank opening is provided with an outer groove.
Furthermore, the number of the outer side grooves is two, and the two outer side grooves correspond to the anti-theft ring and the support ring on the bottle blank respectively.
Further, an outer protrusion located between the two outer grooves protrudes from a side of the outer retainer facing the blank mouth.
Based on the technical scheme, the invention can realize the following technical effects:
1. the auxiliary blank inserting device can effectively prevent the bottle blank from being in a skew state, and the bottle blank can be normally inserted when moving to the blank inserting opening;
2. the auxiliary blank inserting device can still ensure that the bottle blank is in an upright state and is not inclined under the condition that the support ring of the bottle blank opening is damaged, so that the occurrence of the clamping and stopping condition of the bottle blowing machine is avoided, and the production efficiency is effectively improved;
3. the inner side groove and the outer side groove of the auxiliary blank inserting device are matched with the support ring and the anti-theft ring on the bottle blank opening, so that the bottle blank is ensured to be upright on one hand, and on the other hand, the bottle blank is positioned, the bottle blank is prevented from falling off and damaging a lamp tube of the heating machine, the waste is reduced, and the production cost is reduced;
4. the auxiliary blank inserting device effectively reduces the failure shutdown times in the actual use process, and improves the stability of equipment.
