Description

Technical Field

[0001] The utility model belongs to the field of filling, and specifically relates to a filling device. Background Art

[0002] In the field of aseptic filling, the clamping operation of the container is one of the basic functions of the whole machine. Only in this way can the operations such as cleaning, drying, filling and sealing of the container be implemented. In other words, the clamping operation is the basic function throughout the entire aseptic filling process.

[0003] The condition for aseptic filling operation is that the space is sterile. However, in the current existing technology, the mechanical parts in the aseptic filling space cannot reach a sterile state, because the power components such as motors, cylinders, electric cylinders, etc. used to drive the clamps in the aseptic filling space cannot be thoroughly sterilized. Although these power components have a neat appearance, their interior cannot be sterilized, and their surfaces have various gaps that are directly connected to the interior due to assembly. Therefore, the substances inside the power components will penetrate into the aseptic filling space through the gaps on the surface, thereby destroying the sterile state of the space, so that the sterile state of the aseptic filling space can only be maintained for a short period of time. After a certain period of time, the probability of bacteria growing in the space will greatly increase. Utility Model Content

The pneumatic cylinder is connected to the end of the opening and closing rod to drive the two clamping jaws to move closer or farther through the opening and closing rod.

[0036] Embodiment 1:

[0037] A filling device, such as Figures 1 to 3As shown, it includes a sterile warehouse 100, a clamping component 300, a transmission component 400, a power component and a steam barrier warehouse 200. The sterile warehouse 100 is a sterile environment. An opening is provided on one side of the sterile warehouse 100. The steam barrier warehouse 200 is provided at the opening of the sterile warehouse 100 to separate the internal environment of the sterile warehouse 100 from the outside world, to prevent the outside air from entering the sterile warehouse 100 through the opening of the sterile warehouse 100, and to ensure that the sterile warehouse 100 always maintains a sterile environment. The clamping component 300 is located in the sterile warehouse 100 as a whole, the power component is located outside the sterile warehouse 100 and the steam barrier warehouse 200 as a whole (i.e., the outside world), one end of the transmission component 400 is located in the outside world and connected to the power component, and the other end passes through the steam barrier warehouse 200 and extends into the sterile warehouse 100 to be connected to the clamping component 300. The transmission component 400 transmits between the clamping component 300 and the power component. The transmission component 400 moves under the drive of the power component. The moving transmission component 400 can drive the clamping component 300 to open and close to clamp the sheet, and at the same time can drive the clamping component 300 to translate to drive the clamped sheet to move in the sterile warehouse 100 to realize the transportation of the sheet.

[0038] The utility model sets a steam barrier chamber 200 on one side of the sterile chamber 100 to separate the sterile chamber 100 from the outside, thereby preventing the outside air from entering the sterile chamber 100 to ensure the sterile environment of the sterile chamber 100. The utility model sets all the clamping components 300 that can be thoroughly sterilized in the sterile chamber 100, and sets the power components that are difficult to be thoroughly sterilized outside the sterile chamber 100. The transmission component 400 that passes through the steam barrier chamber 200 and extends into the sterile chamber 100 transmits the power between the clamping components 300 located in the sterile chamber 100 and the power components located outside the sterile chamber 100, so that the power components 400 can be sterilized in the sterile chamber 100. The force component can stably drive the clamping component 300 in the sterile warehouse 100 outside the sterile warehouse 100, control the clamping component 300 to clamp or release the sheet and drive the sheet to move in the sterile warehouse 100, and the steam barrier warehouse 200 can prevent bacteria in the outside air and bacteria carried by the power component from entering the sterile warehouse 100. It can also use high-temperature steam to sterilize the transmission component 400 passing through it, so as to prevent the transmission component 400 from carrying bacteria from the outside into the sterile warehouse 100 during movement, so that the sterile warehouse 100 can maintain a sterile environment for a long time, thereby ensuring stable aseptic filling.

[0039] In this embodiment, the clamping component 300 includes a base 310, a pushing component 330 and two clamping jaws 320. The two clamping jaws 320 are slidably connected to the base 310. The pushing component 330 is connected to the two clamping jaws 320 and can drive the two clamping jaws 320 to slide on the base 310. The transmission component 400 includes a moving rod 410 and an opening and closing rod 420. The extension directions of the moving rod 410 and the opening and closing rod 420 are parallel. The opening and closing rod 420 is connected to the pushing component 330. The opening and closing rod 420 drives the pushing component 330 to move by translation. The pushing component 330 drives the two clamping jaws 320 to slide and open and close on the base 310 at the same time by moving, so that the two clamping jaws 320 are close to clamp the sheet or move away to loosen the sheet. The movable rod 410 is connected to the base 310 so as to drive the base 310 and the pushing assembly 330 and the clamping jaw 320 installed on the base 310 to translate, that is, the movable rod 410 can drive the clamping component 300 and the sheet clamped by the clamping component 300 to translate as a whole. The translation of the clamping component 300 and the opening and closing of the clamping jaw 320 can be controlled by the movable rod 410 and the opening and closing rod 420. The overall structure is simple and reliable, and the operation is stable.

[0040] Preferably, two slide grooves 311 are provided on the base 310, and the extension directions of the two slide grooves 311 coincide with each other, and the extension direction of the slide grooves 311 is perpendicular to the extension direction of the opening and closing pull rod 420, and the bottoms of the two clamping jaws 320 are slidably connected in the two slide grooves 311 respectively. The pushing assembly 330 includes a pushing member 331 and two push rods 332, and the pushing member 331 is located on one side of the base 310, and one end of the two push rods 332 is rotatably connected to the two clamping jaws 320 respectively, and the other ends of the two push rods 332 are rotatably connected to the pushing member 331, and the pushing member 331 is strip-shaped, and its extension direction is parallel to the extension direction of the slide groove 311, and the connection points of the two push rods 332 are respectively located at the two ends of the pushing member 331, and the end of the opening and closing pull rod 420 is connected to the middle of the side of the push rod 332 away from the base 310. Figure 2 As shown, when the opening and closing rod 420 moves axially toward the base 310, the opening and closing rod 420 pushes the pusher 331 toward the base 310, and the push rod 332 on the pusher 331 drives the two clamping jaws 320 to slide along the slide groove 311 and move closer, so that the two clamping jaws 320 clamp the sheet; Figure 3As shown, when the opening and closing rod 420 moves in the axial direction away from the base 310, the opening and closing rod 420 pulls the pusher 331 away from the base 310, and the push rod 332 on the pusher 331 drives the two clamping jaws 320 to slide and open along the slide groove 311, so that the two clamping jaws 320 are separated to release the sheet. The pusher 331 and the pusher 332 connected in rotation and the clamping jaw 320 are slidably connected in the slide groove 311, and the axial translation of the opening and closing rod 420 is converted into the vertical translation of the clamping jaw 320. The transmission direction is changed by a simple structure, and the transmission component 400 controls the opening and closing and displacement of the clamping component 300.

[0041] In this embodiment, a sliding hole 321 is provided on the clamping jaw 320, which passes through the clamping jaw 320 horizontally. The sliding hole 321 is located in the middle of the clamping jaw 320. A sliding rod 312 is also provided on the base 310. The sliding rod 312 is located above the sliding groove 311. The extension direction of the sliding rod 312 is parallel to the extension direction of the sliding groove 311. The sliding rod 312 passes through the sliding holes 321 of the two clamping jaws 320 horizontally so that the clamping jaw 320 is slidably connected to the sliding rod 312. The setting of the sliding rod 312 can guide and limit the clamping jaw 320, limit the sliding trajectory of the clamping jaw 320, and support the middle part of the clamping jaw 320 to prevent the free end of the clamping jaw 320 from shaking, so that the clamping jaw 320 can clamp the sheet more stably and reliably.

[0042] The power components in this embodiment include a pneumatic cylinder and an electric cylinder. The output shaft of the pneumatic cylinder is connected to the end of the opening and closing rod 420. The output shaft of the pneumatic cylinder drives the opening and closing rod 420 to move in translation through telescoping. The opening and closing rod 420 drives the two clamping jaws 320 to move closer or farther away through translation. The pneumatic cylinder has the advantage of strong carrying capacity. As a power output structure for driving the opening and closing rod 420, the opening and closing operation of the clamping jaws is more stable and reliable, and the clamping effect on the sheet is better; the output shaft of the electric cylinder is connected to the end of the moving rod 410. The output shaft of the electric cylinder drives the moving rod 410 to move in translation through telescoping. The moving rod 410 drives the clamping component 300 to move in translation through translation. The electric cylinder has the advantages of fast response speed and high control accuracy. As a power output structure for driving the moving rod 410, when it controls the clamping component to transmit the sheet, it can ensure high-precision transmission of the sheet, so that the sheet can be accurately aligned with the filling, sealing and other workstations. Of course, the combination of the air cylinder and the electric cylinder is only a preferred implementation of this embodiment, and other types of linear actuators can also be used as power components to drive the moving pull rod 410 and the opening and closing pull rod 420.

[0043] The movable rod 410 in this embodiment may be provided with one or more. Preferably, the movable rod 410 includes a first movable rod 411 and a second movable rod 412 respectively located on both sides of the opening and closing rod 420. The first movable rod 411 and the second movable rod 412 are arranged in parallel with the opening and closing rod 420, and the ends of the first movable rod 411 and the second movable rod 412 are respectively connected to both sides of the base 310. The combination of the first movable rod 411 and the second movable rod 412 reduces the force on a single movable rod 410, so that the connection between the end of the movable rod 410 and the base 310 is not easily damaged, thereby making the push and pull of the movable rod 410 for the base 310 more stable and reliable. In this embodiment, a guide member 110 is further provided in the sterile warehouse 100, and a guide hole 111 is provided on the guide member 110. The number of the guide holes 111 is the same as the total number of the opening and closing rods 420 and the movable rod 410, so that the movable rod 410 and the opening and closing rod 420 pass through the corresponding guide holes 111 respectively, and the movable rod 410 and the opening and closing rod 420 are slidably connected with the guide member 110, that is, the movable rod 410 can open and close the rod 420 and the axial movement can be performed in the corresponding guide hole 111. The setting of the guide member 110 can support the movable rod 410 and the opening and closing rod 420 to prevent the movable rod 410 and the opening and closing rod 420 from bending, and can also prevent the clamping component 300 from rotating, thereby ensuring that the clamping component 300 is always aligned with the sheet material, so that the clamping component 300 can stably transmit the sheet material.

[0044] The working process of filling equipment is as follows:

[0045] When the clamping jaws 320 are in the open state, the electric cylinder drives the base 310 to move in the opposite direction by moving the pull rod 410. After the base 310 moves into place, the cylinder drives the opening and closing pull rod 420 to move in the direction close to the base 310. The opening and closing pull rod 420 pushes the pusher 331 to move closer to the base 310. The push rod 332 on the pusher 331 drives the two clamping jaws 320 to slide along the slide groove 311 and move closer to the sheet between the two, so that the two clamping jaws 320 clamp the sheet together. Then the electric cylinder drives the clamping component 300 by moving the pull rod 410. After the clamping component 300 moves in the forward direction and drives the clamped sheet to move in the right direction, the cylinder drives the opening and closing rod 420 to move axially away from the base 310, and the opening and closing rod 420 pulls the pushing member 331 away from the base 310. The push rod 332 on the pushing member 331 drives the two clamping jaws 320 to slide and open along the slide groove 311, so that the two clamping jaws 320 release the sheet. The electric cylinder drives the base 310 to move in the reverse direction again by moving the rod 410. The above operation is repeated many times to realize the step-by-step conveying of the sheet by the filling equipment.

[0046] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
