Description

Technical Field

[0001] This application relates to the field of plastic molding technology, and in particular to a clamping and cooling mechanism for an integrated blow-fill-seal device. Background Technology

[0002] Blow-fill-seal (BFS) technology is an advanced manufacturing technology for the production of sterile liquid products, initially used in the pharmaceutical industry. BFS technology integrates the three processes of blow molding, filling, and sealing of a hot-melt plastic preform into a continuous sterile filling production process on a single machine.

[0003] Blow-fill-seal integrated equipment is mainly used in the production of small-volume liquid drugs, vaccines, injections, antibiotics, nutritional supplements, and personal care products. Plastic containers require blow molding during production. The equipment must maintain consistent strokes at both ends of the mold during the mold-closing process to ensure the product's sealing and appearance are up to standard. Furthermore, the product is at a high temperature and has poor plasticity immediately after extrusion, making it prone to twisting and deformation under external forces, resulting in a lower product yield. In addition, the equipment's mechanism is often too complex and inconvenient for subsequent maintenance. Summary of the Invention

[0004] This application provides a clamping and cooling mechanism for an integrated blow molding, filling, and sealing device, which can simultaneously clamp and cool freshly blow-molded products.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides a clamping and cooling mechanism for an integrated blow-fill-seal device, including a material-taking clamping base plate, a linear guide rail fixedly installed on one side of the material-taking clamping base plate, a pair of material-taking clamping mold frames slidably installed on the linear guide rail, and a clamping cylinder for driving the pair of material-taking clamping mold frames to open and close synchronously. Each of the material-taking clamping mold frames is adjustablely connected to a cooling component, and the cooling component is filled with circulating coolant. The cooling component includes a clamping cooling plate for contacting the body of the sealed product and a clamping cooling block for contacting the sealing edge of the sealed product.

[0007] In one possible implementation, a connecting block is fixedly connected to each of the material handling clamping molds, and the clamping cylinder is fixedly installed at the center of the material handling clamping base plate. At least two pairs of guide rods are slidably installed inside the clamping cylinder, and the other end of each pair of guide rods passes through each of the material handling clamping molds and is fixed to the connecting block.

[0008] In one possible implementation, the line connecting each pair of guide rods coincides with the diagonal of the clamping cylinder.

[0009] In one possible implementation, there are two linear guide rails, with eight sliders slidably connected to the two linear guide rails. The bottom of each material-grabbing mold frame is fixedly connected to four sliders. This invention improves the stability of the mechanism during mold opening and closing by adding multiple sliders acting on the material-grabbing mold frame and using diagonally fixed guide rods to push the opening and closing of the material-grabbing mold frame. This ensures consistent movement and smooth operation during mold closing, thereby increasing the product qualification rate.

[0010] In one possible implementation, an mounting plate is fixedly installed on the inner side of each of the material handling clamping mold frames, and a threaded plate is fixedly installed on the outer side of the mounting plate. The mounting plate has multiple elongated slots, the extension direction of which is perpendicular to the linear guide rail. Multiple bolts are threadedly fixed on the threaded plate, and the ends of each bolt pass through the multiple elongated slots on the mounting plate and connect to the clamping cooling plate to achieve adjustable fixation of the clamping cooling plate.

[0011] In one possible implementation, both the clamping cooling plate and the clamping cooling block have water inlets at their front and water outlets at their rear. The interiors of the clamping cooling plate and the clamping cooling block are hollow and connected to the respective water inlets and outlets.

[0012] In one possible implementation, the distance between two opposing surfaces on a pair of clamping cooling plates is greater than the distance between two opposing surfaces on a pair of clamping cooling blocks.

[0013] In one possible implementation, the outer side of the material handling clamp frame has a pipe hole for receiving water pipes or air pipes, which facilitates subsequent maintenance and adjustment of the equipment.

[0014] In one possible implementation, a baffle is bolted to the outside of the material handling clamp frame.

[0015] Compared with the prior art, this utility model adds a clamping cooling plate and a clamping cooling block, which play a role in cooling and shaping while the mechanism is sealing the edges, thus accelerating the product molding process. The clamping cylinder opens and closes outward or inward at the same time, which has the advantages of simple structure and synchronous operation. Attached Figure Description

[0021] To illustrate the technical content, structural features, achieved objectives, and effects of this application in detail, the technical solutions in the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of this application. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of an exemplary embodiment may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0022] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0023] Furthermore, in this application, spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side” (e.g., as in a “sidewall”) are used to describe the relationship between one element and another (other) element as shown in the accompanying drawings. Spatial relative terms are intended to include different orientations of the device in use, operation, and / or manufacture other than those depicted in the drawings. For example, if the device in the drawings is flipped, an element described as “below” or “under” another element or feature would then be positioned “above” said other element or feature. Thus, the exemplary term “below” can include both above and below orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0024] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed connection, a detachable connection, or an integral part; it may be a direct connection or an indirect connection through an intermediate medium.

[0025] The clamping and cooling mechanism of this application's blow-fill-seal integrated equipment is used to clamp and cool freshly shaped plastic products within the equipment. See also Figure 1 As shown, the clamping and cooling mechanism includes: a material picking clamp base plate 1, two linear guide rails 2 fixedly installed on one side of the material picking clamp base plate 1, and a pair of material picking clamp mold frames 4 slidably installed on the two linear guide rails 2. Each of the material picking clamp mold frames 4 is adjustablely connected to a cooling component, which is used to contact and cool the blow-molded product.

[0026] The material gripper base plate 1 can be installed at the end of the material gripping robot. Typically, the material gripper base plate 1 is placed vertically to ensure the overall clamping and cooling mechanism remains horizontal when gripping plastic products. Two linear guide rails 2 are bolted to the material gripper base plate 1, and the two linear guide rails 2 are parallel to each other and parallel to the upper and lower end faces of the material gripper base plate 1, ensuring that the material gripper base plate 1 does not shift during opening and closing. Four sliders 3 are slidably mounted on each of the two linear guide rails 2, for a total of eight sliders 3. Each slider 3 is identical and can slide smoothly on the linear guide rails 2. Two sliders on each side are bolted to a set of material gripping mold frames 4. The material gripping mold frame 4, fixed by the four sliders 3, can move more stably and accurately on the linear guide rails 2, ensuring that the position of the clamping and cooling mechanism does not shift during opening and closing.

[0027] See Figure 2 , 3 As shown, a clamping cylinder 9 is bolted between two linear guide rails 2 on the material-grabbing clamping base plate 1, and the clamping cylinder 9 is located at the center of the material-grabbing clamping base plate 1. Four guide rods 11 are slidably installed inside the clamping cylinder 9, in pairs, each connected to a material-grabbing clamping mold frame 4. Specifically, two guide rods 11 located on the same diagonal line of the clamping cylinder 9 form a pair. Under pneumatic action, each pair of guide rods 11 moves synchronously to the left and right, improving the stability of the clamping and cooling mechanism during the opening and closing process. Connecting blocks 10 are also fixedly installed on the outer ends of each pair of guide rods, located on both sides of the material-grabbing clamping mold frame 4. This diagonal installation improves the stability of the connecting blocks 10 during movement. The connecting blocks 10 are bolted to the material-grabbing clamping mold frame 4. When the clamping cylinder 9 pushes the connecting blocks 10 to move to both sides, it in turn pushes the material-grabbing clamping mold frame 4 to open and close.

[0028] An mounting plate 12 is fixedly installed on the inner side of the material handling clamping mold frame 4. The mounting plate 12 is fixedly connected to the material handling clamping mold frame 4. The clamping cooling plate 5 on the outer side of the mounting plate 12 is fixedly installed on the threaded plate 13 on the inner side of the mounting plate 12 by bolts. The mounting plate 12 has a countersunk hole and is threadedly connected to the threaded plate 13. The clamping cooling plate 5 can move up and down slightly on the mounting plate 12 to adjust its height position. A clamping cooling block 6 is fixedly installed on the top of the mounting plate 12 by bolts. The cooling block 6 mainly serves to clamp and cool the plastic products quickly.

[0029] See Figure 3 , 4 The clamping cooling plate 5 has a first water inlet 14 at its upper front end, which provides cold water to the clamping cooling plate 5 for cooling. The clamping cooling plate 5 has a first water outlet 15 at its upper rear end to drain used cold water. The clamping cooling block 6 has a second water inlet 16 at its front end, which provides cold water to the clamping cooling block 6 for cooling. The clamping cooling block 6 has a second water outlet 17 at its rear end to drain used cold water. In this embodiment, the cooling water path inside the clamping cooling block 6 is not connected to the cooling water path inside the clamping cooling plate 5, which allows for precise individual temperature control of the clamping cooling block 6 and the clamping cooling plate 5. The material handling clamping mold frame 4 has pipe holes 8 on its outer side to accommodate water pipes and air pipes, improving the overall aesthetics of the equipment and facilitating maintenance and adjustment. A baffle 7 is bolted to the outer side of the material handling clamping mold frame 4 to protect the air and water pipes of the mechanism.

[0030] The working process of this application is as follows: In the initial state, a pair of material-retrieving clamping mold frames 4 are in an open state. After the blank completes the blowing and pouring process, it enters the clamping and cooling mechanism. At this time, the clamping cylinder 9 starts to work, pulling back the guide rod 11. The guide rod 11 then pulls the connecting block 10 and the material-retrieving clamping mold frame 4 to move towards the center in a closing motion. A pair of clamping cooling plates 5 installed on the material-retrieving clamping mold frame 4 clamp the blank, and the clamping cooling block 6 tightens to seal the edges of the blank. Cold water is introduced into the clamping cooling plates 5 and the clamping cooling block 6 to cool and shape the blank. After completion, the clamping cylinder 9 pushes the guide rod 11 to move to both sides again, releasing the blank, and the blank then enters the next production process. The clamping and cooling mechanism has completed its work.

[0031] This utility model has a simple structure, high efficiency, and stable operation, which improves the stability of the blow-fill-seal integrated equipment, speeds up the production process, reduces the maintenance cost of the mechanism, and ensures the product qualification rate.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the inventive spirit and scope.
