Description

Technical Field

[0001] This application relates to the field of packaging equipment technology, and in particular to a mold closing system and a blow-fill-seal device. Background Technology

[0002] Blow-fill-seal (BFS) equipment is a fully automated aseptic production equipment that integrates three processes: blow molding, product filling, and bottle sealing.

[0003] In existing technologies, blow-fill-seal (BFS) equipment has two types of mold-closing structures: multi-mold continuous BFS equipment and dual-mold continuous BFS equipment. Multi-mold continuous BFS equipment has high working efficiency and large production capacity because it is equipped with more than 14 sets of molds. However, due to the configuration of multiple sets of molds, the equipment cost is very high, which is difficult for most companies to accept. Moreover, the width of its molds is fixed, making it impossible to design molds to maximize the material utilization rate of each specification when producing multiple specifications, thus failing to maximize the utilization of raw materials. Dual-mold continuous BFS equipment is equipped with larger molds in order to increase production capacity, which usually results in poor maintenance and repair convenience. In addition, because dual-mold continuous BFS equipment has a preform clamping device, it is impossible to design molds with zero waste between bottles in the longitudinal direction, resulting in low raw material utilization. Summary of the Invention

[0004] The purpose of this application is to provide a mold closing system and a blow-fill-seal equipment to solve the problem that existing technologies cannot fully utilize raw materials.

[0005] To achieve the above objectives, this application provides a mold closing system, including: a frame, a first mold closing mechanism, and a second mold closing mechanism;

The support plate is mounted on the frame, the drive member is disposed on the support plate, and the push plate is disposed on the output end of the drive member through the fixing member. The push plates in the two mold clamping and locking assemblies can move closer to or further away from each other.

[0010] In some embodiments, a plurality of reinforcing ribs are provided between the support plate and the frame.

[0011] In some embodiments, the outer sides of the first fixing plate, the second fixing plate, the third fixing plate and the fourth fixing plate are all provided with a mold-locking sliding assembly, the push plate abuts against the mold-locking sliding assembly, and the mold-locking sliding assembly is used to bear the pressure applied by the push plate.

[0012] In some embodiments, the mold-locking sliding assembly includes a first mounting base, a second mounting base, and a bearing. The first mounting base and the second mounting base are spaced apart. The two ends of the bearing are rotatably connected to the first mounting base and the second mounting base, respectively. The outer surface of the bearing can abut against the push plate.

[0013] In some embodiments, the first fixing plate, the second fixing plate, the third fixing plate, and the fourth fixing plate are each provided with a plurality of the mold-locking sliding components, and the plurality of mold-locking sliding components are distributed at intervals along the length direction of the first fixing plate, the second fixing plate, the third fixing plate, or the fourth fixing plate.

[0014] In some embodiments, the top of the first mold, the second mold, the third mold, and the fourth mold are all provided with positioning grooves, and the bottom of the first mold, the second mold, the third mold, and the fourth mold are all provided with positioning blocks, the outer dimensions of the positioning blocks matching the outer dimensions of the positioning grooves.

[0015] In some embodiments, the first lifting assembly includes a driving member, a lifting guide rail, and a sliding block. The driving member and the lifting guide rail are both mounted on the frame, the sliding block is slidably engaged with the lifting guide rail, and the driving member is used to drive the sliding block to move up and down along the lifting guide rail.

[0016] In some embodiments, the mold-closing system described in any one of the foregoing descriptions is included.

[0017] Compared to the background technology described above, the mold-closing system provided in this application includes a frame, a first mold-closing mechanism, and a second mold-closing mechanism. The first mold-closing mechanism includes a first lifting component, a first translation component, a first fixed plate, a second fixed plate, a first mold, and a second mold. The first lifting component is mounted on the frame, the first translation component is mounted on the first lifting component, the first fixed plate and the second fixed plate are mounted on the two output ends of the first translation component, the first mold is mounted on the first fixed plate, and the second mold is mounted on the second fixed plate. The first lifting component is used to drive the first translation component to move up and down, and the first translation component is used to drive the first mold and the second mold to close and open.

[0018] The extrusion equipment extrudes a continuous plastic preform above the frame. The preform moves downwards under gravity. When the first mold-closing mechanism is in the upper mold-closing position, the preform is located between the first and second molds. The first translation component drives the first and second fixed plates to bring the first and second molds closer together until they abut against each other, thus achieving mold closing. After mold closing, the first and second molds descend synchronously with the plastic preform under the action of the first lifting component. Simultaneously, the third and fourth molds in the second mold-closing mechanism are in the open state and located outside the first and second molds. As the first and second molds descend, the third and fourth molds move upwards under the action of the second lifting component. When the second mold-closing mechanism is in the upper mold-closing position, the plastic preform is located between the third and fourth molds, and mold closing begins. When the first and second molds move downwards to their lowest point, the plastic preform is formed. When the third and fourth molds close, the first and second molds open synchronously. The first and second mold clamping mechanisms alternately perform mold clamping and opening operations to achieve continuous molding of plastic preforms. The first and second molds, as well as the third and fourth molds, can be customized according to the height dimensions of plastic bottles of different specifications, so as to maximize the utilization of multiple specifications on the same equipment. At the same time, the mold clamping system in this application can directly clamp the preform through the two molds, and can achieve zero waste design between bottles in the longitudinal direction, improve the utilization rate of raw materials, and reduce production costs.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.

[0029] like Figures 1 to 4As shown, the mold-closing system provided in this application embodiment includes a frame 1, a first mold-closing mechanism 2, and a second mold-closing mechanism 3. The first mold-closing mechanism 2 includes a first lifting component 21, a first translation component 22, a first fixing plate 23, a second fixing plate 24, a first mold 25, and a second mold 26. The first lifting component 21 is mounted on the frame 1, the first translation component 22 is mounted on the first lifting component 21, the first fixing plate 23 and the second fixing plate 24 are mounted on the two output ends of the first translation component 22, the first mold 25 is mounted on the first fixing plate 23, and the second mold 26 is mounted on the second fixing plate 24. The first lifting component 21 is used to drive the first translation component 22 to move up and down, and the first translation component 22 is used to drive... The first mold 25 and the second mold 26 are closed and opened. The second mold closing mechanism 3 includes a second lifting component 31, a second translation component 32, a third fixing plate 33, a fourth fixing plate 34, a third mold 35, and a fourth mold 36. The second lifting component 31 is installed on the frame 1, the second translation component 32 is installed on the second lifting component 31, the second fixing plate 24 and the third fixing plate 33 are installed on the two output ends of the second translation component 32, the third mold 35 is installed on the third fixing plate 33, and the fourth mold 36 is installed on the fourth fixing plate 34. The second lifting component 31 is used to drive the second translation component 32 to move up and down, and the second translation component 32 is used to drive the third mold 35 and the fourth mold 36 to close and open.

[0030] Understandably, the extrusion equipment extrudes a continuous plastic preform above the frame 1. The plastic preform moves downward under gravity. When the first mold closing mechanism 2 is in the upper mold closing position, the plastic preform is located between the first mold 25 and the second mold 26. The first translation component 22 drives the first fixing plate 23 and the second fixing plate 24 to bring the first mold 25 and the second mold 26 closer to each other until they stop against each other, thereby achieving mold closing. After mold closing, the first mold 25 and the second mold 26 descend synchronously with the plastic preform under the action of the first lifting component 21. At the same time, the third mold 35 and the fourth mold 36 in the second mold closing mechanism 3 are in the open state and are located outside the first mold 25 and the second mold 26. When the first mold 25 and the second mold 26 descend, the third mold 35 and the fourth mold 36 move upward under the action of the second lifting component 31. When the second mold closing mechanism 3 is in the upper mold closing position, the plastic preform is located between the third mold 35 and the fourth mold 36, and mold closing begins. When the first mold 25 and the second mold 26 move downwards to their lowest positions, the plastic preform is formed. When the third mold 35 and the fourth mold 36 close, the first mold 25 and the second mold 26 open simultaneously. The first mold closing mechanism 2 and the second mold closing mechanism 3 alternately and cyclically perform mold closing and opening operations to achieve continuous molding of the plastic preform. The first mold 25, the second mold 26, the third mold 35, and the fourth mold 36 can be customized according to the height dimensions of different specifications of plastic bottles, realizing the design of maximizing the utilization rate of multiple specifications on the same equipment. At the same time, the mold closing system in this application can directly clamp the preform through the two molds, realizing a zero-waste design between bottles in the longitudinal direction, improving the utilization rate of raw materials, and reducing production costs.

[0031] In some embodiments, such as Figure 1 and Figure 4 As shown, a mold clamping and locking assembly 4 is also provided. There are two mold clamping and locking assemblies 4, which are symmetrically distributed on both sides of the frame 1. The mold clamping and locking assembly 4 is used to apply pressure to the first mold 25 and the second mold 26 or the third mold 35 and the fourth mold 36 in the mold clamping state so as to form the preform.

[0032] Understandably, when molding large products, the translation component can only provide the driving force for rapid mold closing, which may not be able to meet the high pressure required for plastic preform compression molding. By setting mold closing locking components 4 on both sides of the mold, pressure is applied to the mold through the mold closing locking components 4, so that the molten plastic preform inside the mold cavity is pressed and fused together, ensuring the welding strength at the bottle joint and the sealing reliability of the bottle mouth.

[0033] Based on the above embodiments, the mold clamping and locking assembly 4 includes a support plate 41, a driving member 42, a fixing member 43, and a push plate 44. The support plate 41 is installed on the frame 1, the driving member 42 is disposed on the support plate 41, and the push plate 44 is disposed at the output end of the driving member 42 through the fixing member 43. The push plates 44 in the two mold clamping and locking assemblies 4 can move closer to or further away from each other.

[0034] Specifically, the support plate 41 is vertically fixed on the side column of the frame 1. The drive component 42 can be a high-thrust hydraulic cylinder. Two drive components 42 are arranged in parallel on both sides of the support plate 41. The push plate 44 is fixedly connected to the output ends of the two drive components 42 through two fixing components 43. The fixing component 43 can be a ball head locking structure in conventional technology. The fixing component 43 includes a ball head and a ball head seat. The ball head is located at the end of the output rod of the drive component 42. The ball head seat is fixedly located on the push plate 44. The ball head seat has a groove corresponding to the ball head. The ball head can extend into the groove to realize the hinge between the output rod of the drive component 42 and the push plate 44.

[0035] In some embodiments, a plurality of reinforcing ribs 45 are provided between the support plate 41 and the frame 1.

[0036] Specifically, the reinforcing rib 45 is a right-angled triangular thick steel plate, with its two right-angled sides welded to the back of the support plate 41 and the side of the frame 1 column, respectively. Multiple reinforcing ribs 45 are evenly distributed along the height direction of the support plate 41.

[0037] Understandably, the reinforcing ribs can improve the bending rigidity of the support plate 41, prevent the support plate 41 from bending and deforming when the drive component 42 outputs a large thrust, ensure that the pressure direction of the push plate 44 is always parallel to the mold closing direction, ensure that the locking force is stably and evenly transmitted to the mold, and improve the mold closing forming accuracy and the long-term reliability of the equipment.

[0038] In some embodiments, such as Figure 2 and Figure 3 As shown, the outer sides of the first fixing plate 23, the second fixing plate 24, the third fixing plate 33 and the fourth fixing plate 34 are all provided with a mold locking sliding assembly 5. The push plate 44 abuts against the mold locking sliding assembly 5, and the mold locking sliding assembly 5 is used to bear the pressure applied by the push plate 44.

[0039] Understandably, the mold locking sliding assembly 5, as the structure for receiving and transmitting the locking force, evenly distributes the concentrated load of the push plate 44 to the mold fixing plate, avoiding direct friction and collision between the push plate 44 and the surface of the fixing plate, thus protecting the precision of the fixing plate.

[0040] Based on the above embodiments, the mold-locking sliding assembly 5 includes a first mounting base 51, a second mounting base 52 and a bearing 53. The first mounting base 51 and the second mounting base 52 are spaced apart. The two ends of the bearing 53 are rotatably connected to the first mounting base 51 and the second mounting base 52 respectively. The outer circular surface of the bearing 53 can abut against the push plate 44.

[0041] Specifically, the bearing 53 can be a roller bearing 53. The first mounting base 51 and the second mounting base 52 are both provided with bearing 53 holes. The central rotating shafts at both ends of the bearing 53 are respectively rotatably engaged with the two bearing 53 holes. The bearing 53 can rotate freely around the rotating shafts, and the outer circular surface of the bearing 53 can form a rolling contact with the push plate 44.

[0042] Understandably, when the mold clamping mechanism moves vertically up and down, the roller bearing 53 can roll on the working surface of the push plate 44, converting traditional sliding friction into rolling friction. This reduces the friction between the bearing 53 and the push plate 44, thereby reducing component wear. Simultaneously, the outer surface of the roller bearing 53 maintains stable line contact with the push plate 44, ensuring uniform and reliable transmission of locking force. Pressure fluctuations do not occur due to the up-and-down movement of the mold, guaranteeing stable pressure during the mold clamping process.

[0043] In some embodiments, the first fixing plate 23, the second fixing plate 24, the third fixing plate 33 and the fourth fixing plate 34 are each provided with a plurality of mold-locking sliding components 5, and the plurality of mold-locking sliding components 5 are distributed at intervals along the length direction of the first fixing plate 23 or the second fixing plate 24 or the third fixing plate 33 or the fourth fixing plate 34.

[0044] Understandably, the multiple locking components are evenly spaced along the length of the corresponding fixed plate, which allows the locking force applied by the push plate 44 to be evenly distributed on the mold, avoiding bending and deformation of the mold and fixed plate due to single-point pressure, ensuring that the mold closing pressure is consistent throughout the mold cavity, thereby ensuring that the molding quality of multiple bottles in the row is uniform and consistent, and eliminating defects such as poor local welding and excessive flash.

[0045] In some embodiments, the top of the first mold 25, the second mold 26, the third mold 35 and the fourth mold 36 are all provided with positioning grooves 61, and the bottom of the first mold 25, the second mold 26, the third mold 35 and the fourth mold 36 are all provided with positioning blocks, and the outer dimensions of the positioning blocks match the outer dimensions of the positioning grooves 61.

[0046] Specifically, the top end face of the first mold 25, the second mold 26, the third mold 35 and the fourth mold 36 are all provided with a recessed positioning groove 61, and the bottom end face is provided with a downwardly protruding positioning block. The outer dimensions of the positioning block and the inner cavity dimensions of the positioning groove 61 are precisely clearance-fitted.

[0047] Understandably, when the first mold closing mechanism 2 and the second mold closing mechanism 3 alternate, the end faces of the two adjacent molds fit together. The positioning block at the bottom of the upper mold can be embedded in the positioning groove 61 at the top of the lower mold, achieving centering and positioning of the upper and lower molds. This ensures the coaxiality and positional accuracy of the upper and lower bottle bodies, avoiding misalignment that could lead to deviations in bottle forming and sealing. Simultaneously, the engagement of the positioning groove 61 and the positioning block can also bear some of the lateral load, improving stability during mold closing and locking, and preventing misalignment of the mold due to lateral forces.

[0048] In some embodiments, the first lifting component 21 includes a drive member 42, a lifting guide rail and a sliding block. The drive member 42 and the lifting guide rail are both mounted on the frame 1. The sliding block is slidably engaged with the lifting guide rail. The drive member 42 is used to drive the sliding block to move up and down along the lifting guide rail.

[0049] It is understood that the second lifting component 31 has the same structure as the first lifting component 21. By setting lifting guide rails, it is possible to prevent the first mold closing mechanism 2 and the second mold closing mechanism 3 from shaking when moving up and down, ensuring the precise alternation and replacement of the two mold closing mechanisms, thereby ensuring the stability of the cycle time for continuous production, and at the same time avoiding motion interference between the two mold closing mechanisms. In this embodiment, the first translation component 22 can be an electric cylinder. The first translation component 22 drives the first fixed plate 23 and the second fixed plate 24 to move closer or further away from each other synchronously through a gear set. The second translation component 32 has the same structure as the first translation component 22.

[0050] The blow-fill-seal equipment provided in this application includes any of the above-mentioned mold-closing systems.

[0051] Specifically, the blow-fill-seal equipment includes an extrusion device and a filling device, both of which are located above frame 1.

[0052] Understandably, the extrusion equipment extrudes a continuous plastic preform from above, the mold clamping system enables continuous high-speed molding of the plastic bottle body and sealing of the bottle head, and the filling equipment fills the product solution into the molded bottle.

[0053] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0054] The mold-closing system and blow-fill-seal equipment provided in this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the solution and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
