Description

Technical Field

[0001] The invention relates to the field of vacuum pouring charging, in particular to a side-opening vacuum pouring tank. Background Art

[0002] The vacuum pouring tank is an indispensable production equipment in the pharmaceutical filling industry. It is a cylindrical steel container with a tank cover, which mainly provides a vacuum environment for product filling. The traditional operation method is mostly manual use of a crane in the workshop to lift the tank cover and place it aside, and then use an overhead crane to place the product vertically into the tank, and then cover the tank cover. This method requires manual participation throughout the process and has poor safety, which is not conducive to the safe mass production of certain products.

[0003] The improved plan attempts to adopt a side-opening door structure to simplify operation, but still faces the following technical bottlenecks: for example, side-opening doors usually need to bear a large weight, and the problem is how to support the side-opening door to achieve stable movement; and if the supporting structure is not rigid enough or the guiding accuracy is low, it is easy to cause the center of gravity of the door to shift when it moves, scratching the tank opening, damaging the sealing surface, and affecting the life of the equipment.

[0004] Therefore, it is urgent to develop a side-opening vacuum pouring tank to solve the above problems. Summary of the Invention

The spring member is orthogonal to the hatch and provides buffering damping through normal elastic deformation, so that the hatch forms a limited displacement in the normal direction.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, a side-opening vacuum pouring tank is characterized by comprising: The tank body has an opening on the side for the product to enter and exit; a support frame, located in front of the opening, for supporting the hatch; a hatch, disposed in the support frame and slidably disposed at the opening, for sealing the opening; a driving mechanism for driving the hatch to open and close the opening laterally; at least one pressure actuator capable of applying pressure and thrust perpendicular to the direction of the door to the door; An elastic support assembly is connected to the hatch, and the elastic support assembly includes an elastic member. The spring member is orthogonal to the hatch and provides buffering damping through normal elastic deformation, so that the hatch forms a limited displacement in the normal direction.

[0009] Furthermore, several of the elastic support components are evenly distributed on the upper end surface of the cabin door; the elastic support component also includes a door shaft and a bracket, and the spring member is a spring; one side of the door shaft is connected to the driving mechanism, and the other side is connected to the bracket through the spring; the lower end of the bracket is fixedly connected to the upper end surface of the cabin door.

[0010] Furthermore, the elastic support assembly also includes a stopper, one side of the bracket is connected to the spring, and the other side is connected to the stopper, and the lower edge of the stopper covers the upper edge of the hatch.

[0011] Furthermore, the tank body is formed by welding an upper flange, a barrel body and a lower flange frame.

[0012] Furthermore, the support frame includes a first transverse support rod and a second transverse support rod arranged horizontally, the first transverse support rod is located above the second transverse support rod, and both are located between the upper flange and the lower flange; the cabin door slides laterally between the first transverse support rod and the second transverse support rod.

[0013] Furthermore, the first transverse support rod is located at the lower end of the upper flange edge, and a V-shaped roller is provided at the upper end of the bracket; when the driving mechanism drives the elastic support assembly to move to the lower end of the upper flange edge, the upper end of the V-shaped roller is connected to the lower end of the upper flange edge, and the rotation axis of the V-shaped roller is parallel to the first transverse support rod.

[0014] Furthermore, the driving mechanism includes a slide rail, a slider and a driving cylinder; the slide rail is located on the first transverse support rod, and the slider is slidably connected to the slide rail; the slider is connected to one side of the door shaft of the elastic support assembly, and the other side of the door shaft is connected to the bracket through the spring, and the lower end of the bracket is connected to the cabin door; the driving cylinder is installed on the support frame to drive the cabin door to move laterally.

[0015] Furthermore, a guide groove is provided on the upper surface of the second transverse support rod, and the lower end of the door frame is connected to a plurality of door-lifting mechanisms, and the door-lifting mechanisms are slidably connected to the guide groove.

A universal wheel is provided in the cylinder. The universal wheel located on the outer side of the cylinder is connected to the side of the guide groove. The other side of the universal wheel is connected to the cylindrical groove of the top door mechanism through a spring. The spring is orthogonal to the cabin door and provides buffering damping through normal elastic deformation.

[0017] Furthermore, the pressure actuator is a door-pressing cylinder, and a plurality of door-pressing cylinders are symmetrically distributed on the left and right sides of the opening.

[0018] Furthermore, the tank cover is provided for sealing the top of the tank body, the surface of the tank cover is provided with reinforcing ribs and a viewing window, and the tank cover is also provided with a discharge pipe passing through the tank cover.

[0019] Furthermore, the opening is a square door frame The beneficial effects of the present invention are: 1. This invention uses the springs of the elastic support assembly and the door lift mechanism to generate a normal elastic force when the pressure actuator is released, causing the door to pop outward slightly, approximately 10 mm, freeing it from the sealing surface of the opening. This prevents direct contact with the opening frame during sliding, completely eliminating the risk of scratching. Simultaneously, a V-shaped roller abuts the lower edge of the upper flange, reducing the resistance to the door's outward movement and improving operational smoothness. The pressure actuator applies uniform normal pressure during the sealing phase, ensuring a tight fit between the door and the opening. Since the door is heavy and prone to deflection during movement, the rebound force of the upper elastic support assembly spring and the lower door lift mechanism spring ensures smooth movement without deflection.

[0020] 2. The present invention replaces the traditional top hoisting with an automatic side opening and closing structure. The product is transported into the tank body through the conveying device in front of the side-opening vacuum pouring tank, completely avoiding the hoisting of the tank cover and the product, reducing two working steps, and improving production efficiency by 50%. The entire production process realizes unmanned automatic operation, improves the safety of the production line, and meets the core needs of modern automated production.

It should be understood that a person of ordinary skill in the art will recognize that the present invention can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0026] Example like Figure 1 and Figure 3 As shown, a side-opening vacuum casting tank includes: a tank body, a support frame 10, a hatch 6, a door-pressing cylinder 5, a pressure actuator, and an elastic support assembly 8; a square door frame 4 for product entry and exit is provided on the side of the tank body; the support frame 10 is located in front of the door frame 4 and is used to support the hatch 6; the hatch 6 is arranged in the support frame 10 and can be laterally slidably arranged on the door frame 4 to seal the door frame 4; a driving mechanism is used to drive the hatch 6 to open and close the door frame 4 laterally; Several door-pressing cylinders 5 are symmetrically distributed on the left and right sides of the door frame 4, and are used to apply pressure and thrust perpendicular to the direction of the door 6 to the door 6; the symmetrically distributed door-pressing cylinders 5 act synchronously to apply balanced normal pressure, avoiding distortion of the sealing surface caused by unilateral force on the door 6, thereby improving the sealing stability in long-term use.

[0027] like Figure 4 As shown, the elastic support assembly 8 is connected to the hatch 6 and includes a spring 17. This spring 17 is orthogonal to the hatch 6 and provides damping through normal elastic deformation, allowing the hatch 6 to experience limited displacement in the normal direction. When the door-pressing cylinder 5 is released, the spring 17 of the elastic support assembly 8 generates a normal elastic force, which pushes the hatch 6 outward slightly, approximately 10 mm, freeing the hatch 6 from the sealing surface of the door frame 4. This prevents direct contact with the door frame 4 during sliding and completely eliminates the risk of scratching.

[0028] In a preferred embodiment, three elastic support assemblies 8 are evenly distributed on the upper end surface of the hatch door 6. The elastic support assemblies 8 also include a door shaft 14, a bracket 16, and a stopper 18. One side of the door shaft 14 is connected to the drive mechanism, and the other side is connected to one side of the bracket 16 via the spring 17. The other side of the bracket 16 is connected to the stopper 18. The lower end of the bracket 16 is fixedly connected to the upper end surface of the hatch door 6, and the lower edge of the stopper 18 covers the upper edge of the hatch door 6. The evenly distributed elastic support assemblies 8 connect the door shaft 14 and the bracket 16 via the spring 17. The bracket 16 is connected to the hatch door 6 below, dispersing the concentrated load of the hatch door 6 on the slide rail 7 and reducing wear on the slide rail 7. The rigid connection between the door shaft 14 and the slider ensures efficient transmission of driving force.

[0029] like Figure 2 In a preferred embodiment, the tank body is welded together by an upper flange 1, a barrel body 2 and a lower flange 3. The upper flange 1 is used for installing the tank cover 19, the barrel body 2 provides a sealed space by connecting with the upper flange 1 and the lower flange 3, and the lower flange 3 is used for assembly with the base. Figure 5 As shown, the tank cover 19 is used to seal the top of the tank body. The surface of the tank cover 19 is provided with reinforcing ribs 20 and a viewing window 21. The tank cover 19 is also provided with a feed pipe 22 that passes through the tank cover 19. The reinforcing ribs 20 enhance the structure's ability to resist deformation. The viewing window 21 is made of pressure-resistant quartz glass, which facilitates real-time observation of the internal pouring status. The feed pipe 22 is used for pouring the slurry.

[0030] In which, the support frame 10 includes a horizontally arranged first transverse support rod 12 and a second transverse support rod 13, the first transverse support rod 12 is located above the second transverse support rod 13, and both are located between the upper flange 1 and the lower flange 3; the cabin door 6 is located between the first transverse support rod 12 and the second transverse support rod 13 and slides laterally.

[0031] Among them, Figure 6-8As shown, the upper surface of the second transverse support rod 13 is provided with a guide groove 9. The lower end of the door frame 4 is connected to two door-lifting mechanisms 23, which are evenly distributed at the lower end of the door frame 4 and slidably connected to the guide groove 9. In a preferred embodiment, one side of each door-lifting mechanism 23 is provided with a cylindrical groove, and the corresponding outer surface is provided with a raised cylinder 25. A universal wheel 24 is mounted within the cylinder 25. The universal wheel 24, located on the outer side of the cylinder 25, is connected to the side of the guide groove 9. The other side of the universal wheel 24 is connected to the cylindrical groove of the door-lifting mechanism 23 via a spring 17. The spring 17 is orthogonal to the hatch door 6 and provides buffering damping through normal elastic deformation, thereby achieving limited displacement of the hatch door 6 in the normal direction. The spring 17 generates a normal elastic force when the door-pressing cylinder 5 is released, which pops the hatch 6 outward by a small displacement of about 10 mm, so that the hatch 6 is separated from the sealing surface of the door frame 4, avoiding direct contact with the door frame 4 during sliding, and completely eliminating the risk of scratches.

[0032] The double transverse support rods form a stable sliding track, which, combined with the guide groove 9 at the bottom of the door 6, limits the front and rear displacement of the door 6, ensuring that the door 6 can only move horizontally to avoid jamming caused by sagging due to its own weight. The bottom of the door 6 is connected to the guide groove 9 through the door lifting mechanism 23. In a preferred embodiment, the first transverse support rod 12 is located at the lower end of the edge of the upper flange 1, and a V-shaped roller 15 is provided at the upper end of the bracket 16. When the drive mechanism drives the elastic support assembly 8 to move to the lower end of the edge of the upper flange 1, the upper end of the V-shaped roller 15 contacts the lower end of the edge of the upper flange 1, and the rotation axis of the V-shaped roller 15 is parallel to the first transverse support rod 12. The V-shaped roller 15 cooperates with the edge of the upper flange 1 to reduce movement resistance when the hatch door 6 is pushed open, thereby improving operation smoothness.

[0033] In a preferred embodiment, the driving mechanism includes a slide rail 7, a slider and a driving cylinder 11; the slide rail 7 is located on a first transverse support rod 12, and the slider is slidably connected to the slide rail 7; the slider is connected to one side of the door shaft 14 of the elastic support assembly 8, and the other side of the door shaft 14 is connected to the bracket 16 through the spring 17, and the lower end of the bracket 16 is connected to the cabin door 6; the driving cylinder 11 is installed on the support frame 10, and is used to drive the cabin door 6 to move laterally.

[0034] The working process of the present invention is: When the door-pressing cylinder 5 is in a compressed state, the hatch 6 relies on the compression force of the spring 17 of the elastic support assembly 8 and the spring 17 of the door-lift mechanism 23 to fit tightly with the door frame 4, forming a vacuum-sealed environment inside the tank; when the door-pressing cylinder 5 releases pressure, the spring 17 of the elastic support assembly 8 and the spring 17 of the door-lift mechanism 23 rebound and push the hatch 6 outward by 10 mm, completely separating the hatch 6 from the sealing surface of the door frame 4, thus avoiding scratches during subsequent sliding. The drive cylinder 11 is then started, and the door shaft 14 is driven to move horizontally through the slide rail 7 and the slider, and the hatch 6 slides horizontally synchronously therewith, with the lower guide groove 9 providing motion trajectory guidance until the door frame 4 is fully opened. At this time, the external conveying device can deliver the product directly into the tank from the front door frame 4 without the need for lifting assistance.

[0035] After the product is delivered, the driving cylinder 11 moves in the reverse direction, and the door 6 moves back along the slide rail 7 to close the door frame 4. Finally, the door pressing cylinder 5 is pressurized again, pushing the door 6 to fit tightly against the door frame 4. The spring 17 of the elastic support assembly 8 is compressed during this process, ensuring that the sealing surface is evenly stressed and a reliable seal is achieved.

[0036] In summary, the side-opening vacuum pouring tank proposed in the present invention replaces the traditional top lifting method with an automatic side opening and closing structure, simplifies the operating process, eliminates safety hazards, and meets the core needs of modern automated production.
