Description

Technical Field

[0001] The invention relates to the technical field of food and medicine packaging, and in particular to a multi-mode continuous blow-fill-seal device. Background Art

[0002] Blow Fill Seal (BFS) technology is an aseptic filling technology widely used in the pharmaceutical, cosmetics and other industries, especially continuous BFS, which is increasingly used due to its excellent aseptic packaging capabilities and high production capacity. Multi-mode continuous BFS uses multiple molds that rotate continuously around the parison to form the container and complete the filling inside the parison. This model is compatible with products with a capacity of 0.4 to 20 ml. The chain mold used in the existing continuous BFS operates continuously. When the ampoule bottle is demolded, it only relies on the mold in the upper mold to clamp the ampoule belt. There is a disadvantage that the ampoule bottle is prone to sticking to the mold during demolding, which causes the neck of the ampoule to twist and affects the appearance of the product. This phenomenon is more obvious for ampoules with an inverted shape of more than 5 ml. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a multi-mode continuous blowing, filling and sealing equipment that provides guidance for the unloading of the molding material chain, reduces the shaking and deviation of the material chain during unloading, and further assists the demolding of the material chain, avoids mold sticking, and improves the appearance.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] The connecting seat includes a supporting plate and a fixing plate. The first guide plate and the second guide plate are detachably arranged on the corresponding supporting plates. The supporting plate is movably arranged on the fixing plate. The moving direction is the direction in which the first guide plate and the second guide plate are relatively approaching and moving away from each other. The fixing plate is detachably connected to the mounting seat.

[0010] The fixing plate is provided with a waist-shaped hole, and the supporting plate can move in the waist-shaped hole and be locked by a first locking member.

[0011] The mounting seat is provided with a clamping groove, and clamping blocks are provided at both ends of the fixing plate. The clamping blocks are slidably arranged in the clamping groove, and the clamping blocks are provided with a second locking member for locking with the mounting seat.

[0012] The mounting seat is provided with a telescopic drive, the first guide plate and the second guide plate are respectively connected to the telescopic ends of the corresponding telescopic drive, and the telescopic drive is used to drive the corresponding guide plate to move obliquely.

[0013] The first guide plate and the second guide plate are both provided with pre-guide slopes on their tops.

[0035] In the multi-mode continuous blowing, filling and sealing equipment, the tube blank extrusion component 5 extrude the tube blank and form it through the forming mold 1. After the material chain 3 is formed, the guide mechanism 2 forms a guide channel 23 to guide the formed material chain 3, thereby reducing the shaking and deviation of the formed material chain 3 during material unloading, thereby assisting the material chain 3 in demolding, avoiding the adhesion of the material chain 3 to the forming mold 1 and causing the neck to be twisted, thereby improving the aesthetics of the product.

[0036] Furthermore, if Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the guide mechanism 2 includes a first guide plate 21 and a second guide plate 22, and the guide channel 23 is located between the first guide plate 21 and the second guide plate 22. The guide channel 23 is arranged along the discharge direction of the material chain 3 and is close to the mold opening of the molding mold 1. After the material chain 3 is formed, the first guide plate 21 and the second guide plate 22 are in place to form the guide channel 23. The guide channel 23 is arranged along the discharge direction to facilitate limiting the unloading direction of the material chain 3 after the material is discharged, and the guide channel 23 is close to the mold opening of the molding mold 1, which is further convenient for assisting the demolding of the material chain 3.

This facilitates the installation and removal of the first guide plate 21 and the second guide plate 22 after the material chain 3 is formed.

[0038] Furthermore, if Figure 4 and Figure 5As shown, in this embodiment, the connection seat 24 includes a support plate 241 and a fixed plate 242, the first guide plate 21 and the second guide plate 22 are detachably arranged on the corresponding support plate 241, the support plate 241 is movably arranged on the fixed plate 242, the moving direction is the direction in which the first guide plate 21 and the second guide plate 22 are relatively close to and away from each other, and the fixed plate 242 is detachably connected to the mounting seat 4. By adjusting the installation position of the support plate 241 on the fixed plate 242, the first guide plate 21 and the second guide plate 22 can be relatively close to or away from each other, so as to adjust the width of the guide channel 23, adapt to the guidance of containers of different specifications, and improve adaptability, and the guide plate and the support plate 241, the fixed plate 242 and the mounting seat 4 are all detachably connected, which is convenient for disassembly and assembly.
