DETAILED DESCRIPTION

[0050] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0051] like Figure 2-16 The non-sterile bag filling device described in this embodiment is shown, and the non-sterile bag includes a cover 9. Figure 1 As shown, the mouth cover 9 includes a seat body 91 and a cover body 92 which is sealed with the seat body 91. The seat body 91 is connected to the bag body of the non-sterile bag, and a bag mouth is formed on the seat body 91, through which the filling and storage of materials can be realized. The above-mentioned mouth cover 9 and the non-sterile bag containing the mouth cover 9 are conventional components of the prior art.

[0052] The filling equipment of this embodiment includes a cover 9 pressing and pulling mechanism and a cover 9 clamping mechanism. The cover 9 pressing and pulling mechanism includes a base 1, an upper support 2, a lower support 3, a first driving mechanism 4, and a cover 9 mold 31. Among them, the base 1 is fixedly arranged on the frame structure. The base 1 has two substrates arranged at a relative interval on the left and right. A slide groove 12 extending in the front and rear directions is processed on the two substrates. A guide structure 11 is processed below the slide groove 12 on the two substrates. The guide structure 11 is arranged on the substrates on both sides. The guide structure 11 is a guide groove structure, including an upper and lower extension section 111, and an oblique extension section 112 extending from the top of the upper and lower extension section 111 to the front or rear side, and the upper and lower extension sections 111 and the oblique extension section 112 are smoothly transitionally connected. Rollers 81 are installed on the left and right sides of the upper support 2. The roller 81 is inserted into the slide groove 12 in a rolling or sliding manner, so that the upper support 2 can be moved forward and backward and installed on the base 1. The matching mode of the above-mentioned roller 81 and the slide groove 12 is common knowledge in the art. The above-mentioned lower support 3 is arranged below the upper support 2, and the roller 81 is installed on the lower support 3 corresponding to the guide structure 11. The roller 81 is movably inserted in the guide structure 11, so that the lower support 3 can move along the extension direction of the guide structure 11 to form a guide match with the guide structure 11. The above-mentioned first driving mechanism 4 is fixed on the upper support 2, and its driving end is connected to the lower support 3. Through the first driving mechanism 4, it is used to drive the lower support 3 to move up and down, so that the lower support 3 is close to or away from the upper support 2. The mold 31 of the mouth cover 9 is fixed on the lower support 3 so that it can move with the upper support 2. Through the above-mentioned structural design, under the drive of the first driving mechanism 4, the lower support 3 can move back and forth in the upper and lower extension sections 111 and the oblique extension section 112 of the guide structure 11. When the lower support 3 moves in the upper and lower extension sections 111, it can drive the mold 31 of the mouth cover 9 to move up and down. When the lower support 3 moves in the obliquely extending section 112 , it can move toward the front side or the rear side of the base 1 .

[0053] The above-mentioned mold 31 of the mouth cover 9 has a plug-in structure for front-to-back plugging with the cover body 92 of the mouth cover 9. The plug-in structure is a plug-in cavity 32 arranged on the bottom surface of the mold 31 of the mouth cover 9 and extending front and back. The front side of the plug-in cavity 32 forms a socket for the cover body 92 to enter and exit. The side walls on the left and right sides of the plug-in cavity 32 are processed with slots 33 extending front and back. The front end of the slot 33 forms a socket, and the rear end is closed. In the specific structural design, a circle of first annular protrusions 921 are processed on the outer peripheral surface of the cover body 92 of the above-mentioned mouth cover 9. The cover body 92 of the mouth cover 9 can be plugged into the plug-in cavity 32, and the cover body 92 abuts against the rear end of the plug-in cavity 32, and the first annular protrusion 921 on the cover body 92 is synchronously plugged with the slot 33 front and back. Through the above-mentioned structural design, the cover body 92 inserted on the mold 31 of the mouth cover 9 can be limited up and down and positioned in the plug-in cavity 32.

[0054] The aforementioned clamping mechanism of the mouth cover 9 is installed below the pressing and pulling mechanism of the mouth cover 9, and has a clamping space 73. The clamping space 73 has a clamping state for clamping the seat body 91 of the mouth cover 9, and a loosening state for inserting the seat body 91 of the mouth cover 9 into the clamping space 73 or leaving the clamping space 73. When the mouth cover 9 is in the first assembly state, its seat body 91 can be inserted into the clamping space 73 and clamped, and its cover body 92 can be synchronously plugged into the aforementioned plug-in cavity 32 and limited up and down.

[0055] Specifically, the above-mentioned clamping mechanism of the mouth cover 9 includes a support plate 6, a clamp plate 7, and a third driving mechanism 42. The support plate 6 is fixedly arranged on the frame structure. The two clamp plates 7 are relatively movable and arranged on the support plate 6, and the support plate 6 supports the two clamp plates 7. The above-mentioned clamping space 73 is formed between the two clamp plates 7. In the clamping state, the two clamp plates 7 are close to each other so as to be able to clamp the seat body 91 of the mouth cover 9. In the loosened state, the two clamp plates 7 are separated from each other, and the two clamp plates 7 are separated from each other to form an inlet and outlet channel for front and rear plug-in cooperation with the seat body 91 of the mouth cover 9. It should be noted that in this clamping state, at least the up and down movement of the seat body 91 of the mouth cover 9 can be restricted. By reasonably designing the specific structure of the clamp plate 7, the rotation and horizontal movement of the seat body 91 of the mouth cover 9 in the clamping state can also be restricted. In this embodiment, a recessed structure is processed on the opposite surfaces of the two clamp plates 7. In this clamping state, the recessed structures on the two clamp plates 7 cooperate with each other to clamp the seat body 91 of the mouth cover 9.

[0056] In this embodiment, one end of the aforementioned nipper 7 is inserted into the support plate 6 through a pin, and the nipper 7 rotates around the central axis of the pin to have a rotating end rotatably connected to the support plate 6. A gear 72 is coaxially fixed on the rotating end of the nipper 7. The gear 72 is a sector gear 72. The gears 72 on the two nippers 7 mesh with each other. Through the above structural design, when the nipper 7 on one side rotates, the nipper 7 on the other side rotates accordingly. The aforementioned third driving mechanism 42 is arranged on the side of the nipper 7 to drive the two nippers 7 to move closer to or away from each other. The third driving mechanism 42 is preferably a cylinder. A floating joint is installed on the driving end of the cylinder. A pin rod 71 is installed on one of the nippers 7. The central axis of the pin rod 71 is parallel to the central axis of the aforementioned pin. The floating joint is sleeved on the pin rod 71. The back and forth movement of the driving end of the cylinder drives the pin rod 71 to move, thereby driving the nipper 7 on the corresponding side to rotate.

[0057] The lower support 3 has a loading position, a cover-pulling position and a return-pressing position that move in the upper and lower extension sections 111. The cover-pulling position is higher than the loading position. The return-pressing position is lower than the loading position. The above-mentioned mouth cover 9 has a first combination state corresponding to the loading position and a second combination state corresponding to the return-pressing position. In the first combination state and the second combination state, the cover body 92 is pressed on the seat body 91 to close the bag mouth. In the first combination state, the cover body 92 and the seat body 91 are pressed and assembled with each other, and the cover body 92 has a first pressing depth relative to the seat body 91. In the second combination state, the cover body 92 and the seat body 91 are pressed and assembled with each other, and the cover body 92 has a second pressing depth relative to the seat body 91. The above-mentioned first pressing depth is less than the second pressing depth. Through the above-mentioned structural design, the pressing degree of the cover body 92 in the second combination state is greater than the pressing degree in the first combination state, so that the cover body 92 is more difficult to pull out of the seat body 91 in the second combination state.

[0058] When the lower support 3 is in the loading position, the seat 91 of the mouth cover 9 in the first combination state can be inserted between the two clamps 7 in the front-to-back direction, and the cover 92 of the mouth cover 9 can be plugged with the mouth cover 9 mold 31 synchronously. When the lower support 3 and the mouth cover 9 mold 31 are driven to move upward to the cover removal position, the mouth cover 9 mold 31 drives the cover 92 of the mouth cover 9 to move upward, so that the cover 92 and the seat 91 are separated from each other. Among them, when the mouth cover 9 mold 31 drives the cover 92 to move downward to the return and clamping position, the cover 92 can be pressed down onto the seat 91 to form the second combination state of the mouth cover 9. The degree of compression of the cover 92 of the mouth cover 9 in the return and clamping position is higher than that of the mouth cover 9 in the loading position, so as to realize the final compression assembly form of the mouth cover 9, save time and labor, adapt to the compression requirements of different types of mouth covers 99, and have strong practicality.

[0059] In this embodiment, the lower support 3 has a filling position that moves to the oblique extension section 112. The filling device of this embodiment includes a filling valve 5 and a second drive mechanism 41. It should be noted that the filling valve 5 is a conventional component of the prior art, and its operating principle is also the prior art.

[0060] The Chinese utility model patent No. 201721276953.6 discloses a non-sterile filling device, and the technical scheme thereof discloses the operating principle of the filling valve 5 of this embodiment. The filling valve 5 is used to fill non-sterile bags. The filling valve 5 is movably mounted on the upper support 2 up and down, and has a filling port arranged facing the clamping mechanism of the mouth cover 9. In the aforementioned filling position, the filling port of the filling valve 5 corresponds to the clamping space 73 up and down. The aforementioned second driving mechanism 41 is mounted on the upper support 2, and its driving end is connected to the filling valve 5 to drive the filling valve 5 to move up and down. In the filling position, when the cover body 92 and the seat body 91 of the mouth cover 9 are separated from each other, the filling port of the filling valve 5 can be connected to the bag mouth of the seat body 91 located in the clamping space 73 by driving the second driving mechanism 41, so that the non-sterile bag can be filled. The filling valve 5 of this embodiment is also used to evacuate the non-sterile bag. The filling valve 5 has a vacuum port. The vacuum port and the filling port are used together to form a docking port 51 on the filling valve 5. When in use, the docking port 51 docks with the bag mouth on the seat body 91 to enable filling and vacuuming operations. During the specific filling operation, the material shaft 53 in the filling valve 5 moves upward to connect the material inlet 52 with the docking port 51, and the material is transported from the material inlet 52 for filling. During the specific vacuuming operation, the vacuum shaft 54 ​​moves downward, and the gap space formed between the vacuum shaft 54 ​​and the material shaft 53 is connected to the docking port 51, so that the vacuuming operation is performed through the above-mentioned gap space.

[0061] The filling equipment of this embodiment includes a control box 83, a loading platform 82, a controller, and an induction switch 8. The loading platform 82 is located below the clamping mechanism of the mouth cover 9 so as to be able to carry non-sterile bags and load and unload non-sterile bags. The loading platform 82 is a belt transmission platform or a roller platform. The controller is arranged in the control box 83. The first drive mechanism 4, the third drive mechanism 42, and the induction switch 8 are respectively connected to the controller. The induction switch 8 is set corresponding to the clamp plate 7 or the third drive mechanism 42. The induction switch 8 is preferably a magnetic switch or a photoelectric sensor in the prior art. When the aforementioned clamping mechanism of the mouth cover 9 is switched to the clamping state, the induction switch 8 outputs a trigger signal. The controller receives the trigger signal to control the first drive mechanism 4 to perform the corresponding action.

[0062] In the specific structural design, a circle of second annular protrusions 911 is processed on the outer peripheral surface of the seat body 91 of the aforementioned cover 9. Two second annular protrusions 911 are arranged at intervals up and down. When the seat body 91 is inserted into the clamping space 73, the second annular protrusion 911 on the first side is located below the support plate 6, and the second annular protrusion 911 on the second side is located above the clamp plate 7. Through the coordinated use of the two second annular protrusions 911, the seat body 91 can be limited up and down.

[0063] In specific use, when the lower support 3 is located at the loading position, the seat body 91 of the mouth cover 9 in the first combined state is inserted between the two clamp plates 7 along the front-to-back direction, and the cover body 92 is inserted into the slot 33 and the insertion cavity 32 of the mouth cover 9 mold 31. The two clamp plates 7 are driven to approach each other by the third driving mechanism 42 to clamp the seat body 91 of the mouth cover 9. The lower support 3 is driven by the first driving mechanism 4 to move upward in the upper and lower extension sections 111 of the guide structure 11 to the cover removal position to drive the cover body 92 of the mouth cover 9 to separate from the seat body 91. The first driving mechanism 4 continues to drive the lower support 3 to move upward to the oblique extension section 112 of the guide structure 11 to reach the filling position. In this process, the upper support 2 moves forward or backward synchronously. In this filling position, the pulled-out cover body 92 and the seat body 91 are staggered front to back, and the filling valve 5 is driven to the top of the clamping mechanism of the mouth cover 9, so that the filling valve 5 corresponds to the seat body 91 located on the clamping mechanism of the mouth cover 9 up and down. The second driving mechanism 41 is driven to enable the filling valve 5 to directly dock with the bag mouth on the seat body 91 up and down to perform the filling operation. After the filling is completed, the first driving mechanism 4 drives the lower support 3 to move downward to the aforementioned return and clamping position to press the cover body 92 of the mouth cover 9 against the seat body 91, so that the mouth cover 9 forms the aforementioned second combined state. Finally, the third driving mechanism 42 drives the two clamps 7 to move away from each other to release the clamping of the mouth cover 9.

[0064] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
