TECHNICAL FIELD
[0001] The utility model relates to the technical field of plastic bottle production, in particular to a blow filling and sealing all-in-one machine. BACKGROUND
[0002] Plastic bottles are a kind of common containers with very large demand, and are widely used in many fields, such as food and beverage, medical containers, medicine containers, seasoning containers, etc. The production process of plastic bottles has two-step method (commonly used in the early stage of industry development, i.e. first making bottles, then storing the made bottles for later use according to needs, the preparation and use of bottles are separated, i.e. two-step method) and one-step method (the preparation and use of bottles are on the same production line).
[0003] In recent years, the one-step method has been increasingly recognized by the market. For example, a Chinese patent with application number CN202210193687.X discloses a straight-line injection blow filling and sealing integrated plastic bottle packaging equipment. In the patent (CN202210193687.X), as shown in the attached Figure 1 , a bottle receiving mechanism composed of a transition slide rail 105, a transition mold 106, a lifting power device 107, and a horizontal power device 108 is provided, and a bottle taking mechanism not shown in the attached Figure 1 is provided. When working, the bottle receiving mechanism is started to move the transition mold 106 horizontally between the blank mold assembly 101 and the half mold 103. When the half mold 103 rises to a certain height and the mold is opened, the bottle preform in the half mold 103 automatically falls into the corresponding transition mold 106 below, and then the transition mold 106 drives the bottle preform to return horizontally and exit to the center axis position of the whole machine. At this time, the bottle taking mechanism first descends to take the bottle preform, then moves upward to a certain height and stops to take the bottle preform from the transition mold 106. Finally, the transfer mechanism moves horizontally to take the bottle preform on the bottle taking mechanism and then moves vertically to the next process.
[0004] In the patent, since the transition mold 106 cannot be opened, the bottle taking mechanism is needed to take the bottle preform from the transition mold 106 upward. The addition of the bottle taking mechanism not only makes the whole device complex and increases the manufacturing cost, but also makes the bottle preform exposed to the air for a long time during the operation process of first descending to take the bottle, then moving upward to a certain height and stopping, which results in more heat loss and the need for additional heating before the subsequent pre-blowing or formal blowing, thus consuming energy, increasing cost, and seriously affecting work efficiency.
[0005] On the other hand, as the bottle receiving mechanism has lateral reciprocating movement along the width direction, to avoid interference, the transfer mechanism can only be arranged on one side of the bottle receiving mechanism, that is, the transfer mechanism can only transfer the bottle preform after clamping the bottle preform on one side of the bottle preform, and cannot be arranged on both sides of the bottle preform to clamp the bottle preform and then transfer; in addition, the position where the bottle preform is transferred between the bottle receiving mechanism and the transfer mechanism is the position of the central axis of the whole device, and the subsequent heat preservation device, pre-blowing device, bottle blowing device, filling device, sealing device and output device are arranged along the central axis (the injection molding module 100 is located on one side of the central axis), and when designing, to avoid interference between the transfer mechanism and the bottle receiving mechanism, the transfer mechanism has two actions of lateral and longitudinal directions, and each time, the transfer mechanism first moves laterally to the central axis to take the bottle, then moves longitudinally to the next station, then exits laterally, and finally moves longitudinally back to the initial position to wait, and the movement route is a "mouth" type repeated, so that the transfer mechanism is complex in structure and action process, high in manufacturing cost, and low in working efficiency.

[0018] The utility model has the advantages of the following beneficial effects:
[0019] In the application, the linear transfer device is arranged to replace the action of the existing bottle receiving mechanism and bottle taking mechanism, greatly simplifying the structure of the production line and reducing the preparation cost, and the linear transfer device structure can be simply arranged, and the action and control process are simpler than the action of the existing bottle receiving mechanism and bottle taking mechanism, so that the action precision is high, the control is simple, and the production efficiency is greatly improved due to the great simplification of the action process; secondly, in the prior art, the bottle taking mechanism is arranged to expose the bottle blank to air for a long time and cause serious heat loss, but in the application, the linear transfer device is arranged so that the bottle blank row discharged from the mold can freely fall into the linear transfer device, thereby eliminating the arrangement of the existing bottle taking mechanism, simplifying the overall structure and reducing the preparation cost, and the linear transfer device can also quickly fold to clamp and heat the bottle blank, so that the bottle blank discharged from the mold can be heated in the linear transfer device in a very short time, so that the bottle blank is exposed to air for a very short time and the heat loss is low, so that the bottle blank does not need to be heated again before pre-blowing or formal blowing (in the prior art, the bottle blank discharged from the mold is exposed to air for a long time and is easily cooled, and according to the different materials of the bottle blank, most of the materials need to be heated again before pre-blowing or blowing, but in the application, the bottle blank discharged from the mold is exposed to air for a very short time, so that only a very small number of materials of the bottle blank need to be heated again), thereby reducing energy consumption and cost and improving production efficiency.
[0020] In another aspect, the bottle embryo forming mold, the transfer station, the bottle blowing device, the filling device, the sealing device and the bottle outlet device are arranged along the same central axis, so that the production line is a true linear production line. In the prior art, the injection molding module is horizontally offset from the other devices, so that the bottle receiving mechanism and the other devices form a straight line. Therefore, the prior art is not a strictly linear production line. In addition, in the prior art, the transfer mechanism can only clamp the bottle on one side of the bottle due to the arrangement of the bottle receiving mechanism and the bottle taking mechanism. The transfer mechanism has horizontal and vertical displacement and the displacement path is a "mouth" type connected in sequence. Therefore, the transfer mechanism has a complex structure and a complex operation process, has a high manufacturing cost and a low work efficiency. In the production line of the present application, the linear transfer device is horizontally openable and closable, so that the bottle conveying device can reciprocate along the central axis between adjacent stations. Therefore, the structure of the bottle conveying device can be simply arranged and the operation process is simple, so that the manufacturing cost is greatly reduced and the production efficiency is improved. In addition, in the production line of the present application, the bottle embryo forming mold, the bottle blowing device and the bottle outlet device are existing devices. The filling device and the sealing device are based on the existing devices, so that the mechanical hand in the filling device and the sealing device can slide horizontally to avoid the bottle conveying device when the bottle conveying device enters. Therefore, the mechanical hand of the filling device and the sealing device is changed from the original fixed type to the sliding type, which is simple and easy to operate.

[0036] The embodiments of the present utility model will be described in detail below in combination with the drawings, but the present utility model can be implemented in various different ways limited and covered by the following.
[0037] Referring to Figure 6The utility model discloses a kind of interface blow filling and sealing integrated machines, comprising: rack, linear transfer device 40, handover station, blowing device 60, filling device 70, sealing device 80, bottle outlet device 90 and bottle conveying device are set on the rack, and the bottle inlet and outlet line of bottle in handover station, blowing device 60, filling device 70, sealing device 80 and bottle outlet device 90 is same middle axis 110;Linear transfer device 40 is reciprocatingly arranged between vertical injection molding machine upstream of handover station and handover station along straight line, and linear transfer device 40 is set along the transverse width direction of rack to open and close, to be used for holding and heat preservation by vertical injection molding machine when a row of bottle embryo column freely falls from bottle embryo forming mold 20, and bottle embryo column is transferred to handover station from bottle embryo forming mold 20 along straight line;Bottle conveying device is arranged between handover station and sealing device 80, to be used for simultaneously clamping multiple groups of bottle column arranged in sequence on middle axis 110, so that multiple groups of bottle column are moved to next station along middle axis 110 respectively, and after multiple groups of bottle column are moved to next station respectively, bottle conveying device is retreated to previous station along middle axis 110 again.
[0038] When the interface blow filling and sealing integrated machine of the utility model works, bottle embryo forming mold 20 in vertical injection molding machine starts to make bottle embryo, and after the preparation of bottle embryo is completed, the upper die drives the bottle embryo column arranged in sequence along the longitudinal direction to move upward to be pulled out from the lower die below, in the process of driving the bottle embryo column to move upward by the upper die, linear transfer device 40 slides to the lower side of the upper die along straight line, and linear transfer device 40 is slightly opened or does not need to be opened along the transverse width direction;In the process of driving the bottle embryo column to continue to rise by the upper die, the upper die is opened, all bottle embryos in the bottle embryo column freely fall downward to linear transfer device 40 below, after all bottle embryos enter linear transfer device 40, linear transfer device 40 clamps the bottle embryo column and simultaneously heat preserves the bottle embryo, finally linear transfer device 40 drives the bottle embryo column to slide to handover station along straight line, at this time, bottle conveying device starts to clamp the bottle embryo column of handover station, the bottle body formed by blowing bottle embryo of blowing station, the material bottle formed after filling of filling station, the sealed bottle formed after sealing of sealing station, then bottle conveying device drives the clamped bottle body on each station to move along middle axis to next station, so that the bottle embryo column moves to blowing station, the bottle body moves to filling station, the material bottle moves to sealing station, and the sealed bottle moves to bottle outlet station and is output, then bottle conveying device releases the clamped bottle body again and retreats to previous station along middle axis, to realize continuous production on middle axis.
[0039] In the present application, by setting the linear transfer device 40, the action of the existing bottle receiving mechanism and bottle taking mechanism is replaced, the structure of the production line is greatly simplified, the preparation cost is reduced, the structure of the linear transfer device 40 can be simply set, the action and control process are simpler than the action of the existing bottle receiving mechanism and bottle taking mechanism, thereby the action precision is high, the control is simple, and the production efficiency is greatly improved due to the great simplification of the action process; secondly, in the prior art, due to the action of the bottle taking mechanism, the bottle embryo is exposed to the air for a long time, and the heat loss is serious, and in the present application, by setting the linear transfer device 40, the bottle embryo row discharged from the mold can freely fall into it, thereby eliminating the existing bottle taking mechanism, the overall structure is simple, the preparation cost is low, and the linear transfer device 40 can also be quickly folded to clamp and heat the bottle embryo, avoid the bottle embryo discharged from the mold to be exposed to the air for a long time, so that the bottle embryo discharged from the mold can enter the linear transfer device 40 in a very short time. Heat preservation, thereby the bottle embryo is exposed to the air for a very short time, the heat loss is low, so that the bottle embryo of the subsequent pre-blowing or formal blowing may not need to be additionally heated (in the prior art, due to the long time of the bottle embryo exposed to the air after the mold is discharged, the bottle embryo is easily cooled, according to the different materials of the bottle embryo, most of the materials need to be reheated before pre-blowing or blowing, and in the present application, due to the very short time of the bottle embryo exposed to the air after the mold is discharged, only a very small number of materials of the bottle embryo need to be reheated), thereby reducing the energy consumption and cost, and improving the production efficiency.
[0040] In another aspect, the bottle embryo forming mold 20, the transfer station, the bottle blowing device 60, the filling device 70, the sealing device 80 and the bottle outlet device 90 are arranged along the same central axis 110, so that the production line of the present application is a truly linear production line. However, in the prior art, the injection molding module 100 is laterally offset from the other devices (in fact, the bottle receiving mechanism and the other devices form a straight line), so that the prior art is not a strictly linear production line. In addition, in the prior art, the bottle receiving mechanism and the bottle taking mechanism are arranged, so that the transfer mechanism can only clamp the bottle on one side of the bottle, and the transfer mechanism has horizontal and vertical displacement, and the displacement path is a "mouth" type connected in sequence, so that the transfer mechanism has a complex structure and a complex operation process, has a high manufacturing cost and a low working efficiency. In the production line of the present application, the straight transfer device 40 is arranged to be openable and closable in the horizontal direction, so that the bottle conveying device can reciprocate along the central axis between adjacent stations, so that the structure of the bottle conveying device can be simply arranged, and the operation process is also simple, so that the manufacturing cost is greatly reduced, and the production efficiency is improved. In addition, in the production line of the present application, the bottle embryo forming mold 20, the bottle blowing device 60 and the bottle outlet device 90 are existing devices, and the filling device 70 and the sealing device 80 are arranged on the basis of the existing devices, so that the mechanical hand in the filling device 70 and the sealing device 80 can slide in the horizontal direction to avoid the bottle conveying device, so that the mechanical hand of the filling device 70 and the sealing device 80 is changed from the original fixed state to the sliding state, and the operation is simple and easy.
[0041] Optionally, in the present application, when there are multiple groups of bottle embryo lines in the bottle embryo forming mold 20, the corresponding entire bottle receiving, blowing, filling and sealing integrated machine has multiple parallel and spaced central axes, and each central axis is sequentially provided with a group of bottle embryo lines of the bottle embryo forming mold 20, a transfer station line, a bottle blowing in-out line of the bottle blowing device 60, a bottle body filling in-out line of the filling device 70, a bottle mouth sealing in-out line of the sealing device 80 and a bottle outlet line of the bottle outlet device 90. In actual design, the transfer station, the bottle blowing device 60, the filling device 70, the sealing device 80 and the bottle outlet device 90 are respectively provided with multiple horizontally and sequentially spaced in-out lines corresponding to the bottle embryo forming mold 20.
[0042] Optionally, as shown in FIG. 6, the bottle embryo forming mold 20 is provided with a plurality of bottle embryo lines arranged in parallel and spaced apart in the horizontal direction, and each bottle embryo line is provided with a plurality of bottle embryo forming cavities arranged in parallel and spaced apart in the vertical direction. Figures 2-5As shown, the straight line transfer device 40 comprises a support rail frame for connecting with the rack, a heat preservation mold stripping device 42 slidingly supported on the support rail frame, and a longitudinal movement driving mechanism 43 for driving the heat preservation mold stripping device 42 to act. The heat preservation mold stripping device 42 is transversely opened and closed with a longitudinal line extending in the sliding direction thereof as the opening and closing line, for receiving and heat preserving a row of bottle preform rows freely falling from the bottle preform forming mold 20, and is opened after sliding to the transfer station for the bottle conveying device to clamp and straight line transfer.
[0043] In the utility model, the bottle preform forming mold 20 is formed by removing the transition mold 106 in the corresponding functional module of the existing injection mold 100, and when working, the upper mold of the bottle preform forming mold 20 drives the prepared bottle preform rows arranged in the longitudinal direction to move upward to be pulled out from the lower mold below, the longitudinal movement driving mechanism 43 is started to make the heat preservation mold stripping device 42 slide in the longitudinal direction to the lower side of the upper mold during the process of the upper mold driving the bottle preform rows to move upward, at this time, the heat preservation mold stripping device 42 is slightly opened in the transverse width direction, or the heat preservation mold stripping device 42 can also be directly closed, the upper mold is opened during the process of the upper mold driving the bottle preform rows to continue to move upward, all the bottle preforms in the bottle preform rows freely fall downward to the heat preservation mold stripping device 42 below, the heat preservation mold stripping device 42 clamps the bottle preform rows and heat preserves the bottle preforms after all the bottle preforms enter the heat preservation mold stripping device 42, and finally, the longitudinal movement driving mechanism 43 is started again to make the heat preservation mold stripping device 42 drive the bottle preform rows to straight line slide to the transfer station, the bottle conveying device at the transfer station acts to clamp the exposed bottle preform rows after the heat preservation mold stripping device 42 moves in place at the transfer station, so that the bottle conveying device clamps the bottle preform rows to move in the longitudinal direction to the next station.
[0044] The linear transfer device is simple in structure, high in action precision and simple in control, and greatly improves production efficiency due to the great simplification of the action process; on the other hand, in the prior art, the bottle embryo is exposed to air for a long time and heat loss is serious due to the action setting of the bottle taking mechanism, in the novel device, the demoulded bottle embryo column can freely fall into the heat preservation demoulding device 42, thereby eliminating the setting of the existing bottle taking mechanism, so that the overall structure is simple and the preparation cost is low, meanwhile, the heat preservation demoulding device 42 can also be quickly folded to clamp and heat the bottle embryo, thereby avoiding the long-time exposure of the demoulded bottle embryo to air, so that the demoulded bottle embryo is exposed to air for a very short time and heat loss is low, so that additional heating is not needed before subsequent pre-blowing or formal blowing (in the prior art, due to the long-time exposure of the demoulded bottle embryo to air, according to the different materials of the bottle embryo, most of the subsequent materials of the bottle embryo need to be reheated for pre-blowing or blowing, while in the present application, due to the very short time of the demoulded bottle embryo exposed to air, only a very small number of bottle embryos of different materials need to be reheated), thereby reducing energy consumption and cost, and improving production efficiency.
[0045] Optionally, as shown in Figure 2 The support rail frame comprises a plurality of linear guide rails 411 arranged in sequence and at intervals along the width direction of the rack and extending longitudinally, a support plate 412 horizontally arranged below the plurality of linear guide rails 411, and a plurality of groups of supports 413 connected to the support plate 412 in sequence and at intervals along the length direction of the support plate 412, the linear guide rails 411 and the support plate 412 are respectively connected to the rack, and the heat preservation demoulding device 42 is slidingly arranged on the plurality of linear guide rails 411 to be supported and guided and limited in sliding by the linear guide rails 411.
[0046] Optionally, as shown in Figure 2 and Figure 3As shown, the heat preservation and mold stripping device 42 comprises a pull plate set 421 slidably connected to the support rail frame and connected to the longitudinal movement driving mechanism 43, a clamping plate set 422 arranged in the longitudinal direction, and a transverse movement driving mechanism 423 arranged on the pull plate set 421 and connected to the clamping plate set 422. The clamping plate set 422 comprises a first clamping plate 4221 and a second clamping plate 4222 arranged symmetrically about the arrangement line of the preform array, and the first clamping plate 4221 and the second clamping plate 4222 are respectively connected to the transverse movement driving mechanism 423 to clampingly and heat-preservingly approach each other or to move away from each other so as to linearly transport the preform array along the arrangement line direction thereof. In this alternative, since the first clamping plate 4221 and the second clamping plate 4222 are arranged symmetrically about the arrangement line of the preform array on the preform forming mold 20, the preform array freely falling after the mold stripping can still be arranged in the heat preservation and mold stripping device 42 along the original arrangement line direction, thereby facilitating the subsequent linear transport of the preform array along the arrangement line direction to the handover station.
[0047] As shown in the alternative, Figure 2 and Figure 3 the pull plate set 421 comprises a pull plate arranged horizontally, a plurality of slide blocks slidably arranged on the lower surface of the pull plate and corresponding to the plurality of linear guide rails 411, and a vertical plate vertically connected to the end portions of the pull plate, and the clamping plate set 422 and the transverse movement driving mechanism 423 are arranged on the pull plate. Further, as shown in the alternative, Figure 2 the longitudinal movement driving mechanism 43 comprises a screw rod 431 rotatably arranged on a plurality of supports 413, a driving motor 432 connected to the end portion of the screw rod 431, and a nut 433 cooperatively arranged on the outer circle of the screw rod 431, and the nut 433 is fixed to the vertical plate. In operation, the driving motor 432 is started to drive the connected screw rod 431 to rotate, and the nut 433 cooperatively arranged on the outer circle of the screw rod 431 slides along the length direction of the screw rod 431 when the screw rod 431 rotates, and then the pull plate is slid on the linear guide rail 411 through the fixing of the vertical plate and the nut 433, so as to synchronously drive the clamping plate set 422 to slide relative to the linear guide rail 411, thereby realizing the longitudinal transport of the preforms.
[0048] As shown in the alternative, Figure 3 the first clamping plate 4221 and the second clamping plate 4222 are respectively provided with a plurality of concave accommodation grooves 4220 arranged in the length direction and spaced apart from each other on the opposite opposite faces thereof, and the plurality of accommodation grooves 4220 are arranged one-to-one corresponding to the plurality of preforms included in the preform array to be clamped, so as to stably clamp each preform. In this alternative, the clamping plate set 422 has a simple structure and a low manufacturing cost.
[0049] Preferably, not shown in the figure, the first clamping plate 4221 and the second clamping plate 4222 are respectively made of plastic material to avoid rigidly clamping the preform and damaging it, and can also effectively buffer the impact force during the clamping of the preform to protect it. Alternatively, the receiving groove 4220 is coated with a protective coating for protecting the preform, or a protective sheet for protecting the preform is connected to the inner wall surface of the receiving groove 4220. The protective coating or protective sheet functions as a clamping plate assembly made of plastic material, avoiding rigidly clamping the preform and damaging it, and can also effectively buffer the impact force during the clamping of the preform to protect it.
[0050] Optionally, such as Figure 4 and Figure 5 As shown, to improve production efficiency, the preform forming mold 20 can simultaneously produce multiple rows of preforms arranged at intervals along its width direction. In order to match the production capacity of the preform forming mold 20, the number of clamping plate groups 422 in this invention is also set to multiple groups, and the multiple groups of clamping plate groups 422 are arranged at intervals along the width direction of the pull plate group 421 to correspond to the multiple rows of preforms arranged at intervals along the width direction on the preform forming mold 20. In this embodiment, in order to simplify the overall structure and layout of the device and reduce costs and energy consumption, the multiple groups of clamping plate groups 422 are all arranged on the same pull plate group 421 and are driven to slide by a set of longitudinal movement drive mechanisms 43. In other embodiments, each group of clamping plate groups 422 can also be set separately, that is, multiple sets of heat preservation demolding devices 42 are set on the support rail frame and driven to slide by a set or corresponding multiple sets of longitudinal movement drive mechanisms 43. Even multiple independent linear transfer devices can be set directly.
[0051] When multiple clamping plate groups 422 are arranged on the same pull plate group 421, in order to reduce energy consumption and cost, in this optional scheme, the multiple first clamping plates 4221 of the multiple clamping plate groups 422 are connected by a first connecting rod 4223, and the multiple second clamping plates 4222 of the multiple clamping plate groups 422 are connected by a second connecting rod 4224; the transverse drive mechanism 423 is connected to the outermost first clamping plate 4221 and the second clamping plate 4222. The multiple first clamping plates 4221 are connected as one unit by the first connecting rod 4223, and the multiple second clamping plates 4222 are also connected as one unit by the second connecting rod 4224. At this time, the transverse drive mechanism 423 may include two sets of drive cylinders, which are respectively connected to the outermost first clamping plate 4221 and the second clamping plate 4222.
[0052] Preferably, such as Figure 3To improve the temperature of the bottle preform after the mold is ejected, so as to avoid subsequent reheating operation as much as possible, in the preferred embodiment, the heat preservation ejection device 42 further comprises a heating assembly 424 for heating the clamped bottle preform row, and the heating assembly 424 is arranged in the clamping plate group 422. In the specific embodiment of the preferred embodiment, as shown in Figure 3 The heating assembly 424 comprises a heat preservation insulation pad arranged between the pull plate group 421 and the clamping plate group 422, and a heating member connected with the heat preservation insulation pad; the heating member is a heating coil or a heating pipe arranged along the length direction of the clamping plate group 422. The heat preservation insulation pad is used to keep the heat and avoid rapid heat loss.
[0053] Alternatively, as shown in FIG. 8, the bottle conveying device comprises a bottle clamping frame group, a bottle clamping driving mechanism for driving the lateral movement of the bottle clamping frame group, and a bottle conveying driving mechanism for driving the reciprocating movement of the bottle clamping frame group between adjacent two stations. The bottle clamping frame group comprises a first bottle clamping plate and a second bottle clamping plate arranged symmetrically about the central axis 110, and the first bottle clamping plate and the second bottle clamping plate are respectively connected with the bottle clamping driving mechanism to clamp or release the plurality of bottle rows on the central axis 110. The bottle conveying driving mechanism is connected with the bottle clamping frame group to make the bottle clamping frame group reciprocate along the central axis 110 between adjacent two stations. In the alternative embodiment, the bottle clamping driving mechanism is a driving cylinder, and the opening and closing movement of the bottle clamping frame group is similar to the arrangement of the clamping plate group 422, which is driven by one or more driving cylinders. Similarly, the bottle conveying driving mechanism is also a driving cylinder, which is directly connected with the bottle conveying device to drive the longitudinal reciprocating movement of the bottle clamping frame group. In the alternative embodiment, the bottle clamping frame group can be arranged as a first bottle clamping plate and a second bottle clamping plate arranged symmetrically left and right. Compared with the existing transfer mechanism, the bottle clamping frame group has simple structure, easy to process and prepare, and simple and high-precision movement.
[0054] Alternatively, as shown in Figure 7 and Figure 8 The bottle preheating device 30 and the pre-blowing device 50 are both arranged along the central axis 110, and the bottle preheating device 30 and the pre-blowing device 50 are existing devices.
[0055] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
