DETAILED DESCRIPTION

[0040] 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.

[0041] Embodiment 1

[0042] like Figure 2-10 The figure shows a cover pressing and pulling device for non-sterile bag filling according to this embodiment, wherein the cover 9 of the non-sterile bag of this embodiment is as shown in FIG. Figure 1 As shown, the mouth cover 9 includes a seat body 91 and a cover body 92 that 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 are realized. The above-mentioned mouth cover 9 and the non-sterile bag containing the mouth cover 9 are conventional components of the prior art. The mouth cover 9 has a first combination state and a second combination state when specifically designed. In the first combination state and the second combination state, the cover body 92 is pressed against 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 structural design, the compression degree of the cover body 92 in the second assembly state is greater than that in the first assembly state, so that the cover body 92 is more difficult to be pulled out of the seat body 91 in the second assembly state.

[0043] The flap pressing and pulling device of this embodiment includes a flap clamping mechanism, a flap mold 5, and a first driver 31. Among them, the flap clamping mechanism includes a support plate 1, a pliers plate 2, and a second driver 3. The support plate 1 is fixedly arranged. The two pliers plates 2 are relatively movable and arranged on the support plate 1, and the support plate 1 supports the two pliers plates 2. The two pliers plates 2 have a clamping state close to each other and a release state away from each other. In the release state, the two pliers plates 2 are away from each other to form an entry and exit space for front and rear plug-in cooperation with the seat body 91. In this clamping state, a clamping space for clamping the seat body 91 is formed between the two pliers plates 2. It should be noted that in this clamping state, at least the up and down movement of the seat body 91 can be restricted. By reasonably designing the specific structure of the pliers plates 2, the seat body 91 can also be restricted from rotating and moving in the horizontal direction in the clamping state. The above-mentioned clamping space is adapted to the outer peripheral surface of the seat body 91 to restrict the movement of the seat body 91. Among them, a recessed structure is processed on the opposite surfaces of the two pliers plates 2. In the clamping state, the recessed structures on the two clamp plates 2 cooperate with each other to form a clamping space.

[0044] Specifically, one end of the aforementioned nipper plate 2 is inserted into the support plate 1 through a pin shaft, and the nipper plate 2 rotates around the central axis of the pin shaft to have a rotating end rotatably connected to the support plate 1. A gear 22 is coaxially fixed to the rotating end of the nipper plate 2. The gear 22 is a sector gear 22. The gears 22 on the two nipper plates 2 mesh with each other. Through the above structural design, when the nipper plate 2 on one side rotates, the nipper plate 2 on the other side rotates accordingly.

[0045] The aforementioned second driver 3 is arranged beside the nippers 2 to drive the two nippers 2 to switch back and forth between the clamping state and the release state. The second driver 3 is preferably a cylinder. A floating joint 32 is installed on the driving end of the cylinder. A pin 21 is installed on one of the nippers 2. The central axis of the pin 21 is parallel to the central axis of the aforementioned pin shaft. The floating joint 32 is sleeved on the pin 21. The back and forth movement of the driving end of the cylinder drives the pin 21 to move, thereby driving the nipper 2 on the corresponding side to rotate.

[0046] The aforementioned flap mold 5 is movably arranged above the flap clamping mechanism, and has a plug-in state of front-to-back plugging with the cover body 92. The aforementioned first driver 31 is connected to the flap mold 5 to drive the flap mold 5 to move up and down. The first driver 31 is preferably a cylinder, and the first driver 31 is fixed above the flap mold 5, and its driving end is connected to the flap mold 5 to drive the flap mold 5 to move up and down.

[0047] In the specific structural design, a circle of first annular protrusions 921 is processed on the outer peripheral surface of the cover body 92 of the aforementioned mouth cover 9. A plug-in cavity 51 is processed on the bottom surface of the mouth cover mold 5. The front side surface of the plug-in cavity 51 forms a socket for the cover body 92 to enter and exit. Slots 511 extending forward and backward are processed on the side walls on the left and right sides of the plug-in cavity 51. The front end of the slot 511 forms a socket, and the rear end is closed. In the aforementioned plug-in state, the cover body 92 is plugged into the plug-in cavity 51, and the cover body 92 abuts against the rear end of the plug-in cavity 51, and the first annular protrusion 921 on the cover body 92 is synchronously plugged and matched with the slot 511 front and back. Through the above-mentioned structural design, the cover body 92 inserted on the mouth cover mold 5 can be limited up and down and positioned in the plug-in cavity 51.

[0048] 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 access space, the second annular protrusion 911 on the first side is located below the support plate 1, and the second annular protrusion 911 on the second side is located above the clamp plate 2. Through the coordinated use of the two second annular protrusions 911, the seat body 91 can be limited up and down.

[0049] The mouth cover pressing and pulling device of this embodiment includes a controller and a sensor switch 4. The first driver 31, the second driver 3, and the sensor switch 4 are respectively connected to the controller. The aforementioned sensor switch 4 is arranged corresponding to the clamp plate 2 or the second driver 3. The sensor switch 4 is preferably a magnetic switch or a photoelectric sensor in the prior art. When the aforementioned mouth cover clamping mechanism is switched to the clamping state, the sensor switch 4 outputs a trigger signal. The controller receives the trigger signal to control the first driver 31 to perform a corresponding action.

[0050] The above-mentioned flap mold 5 has a loading position, a flap unloading position, and a return and pressing position in the up and down directions. The flap unloading position is located above the loading position, and the return and pressing device is located below the loading position. When the flap mold 5 is at the loading position, the seat body 91 of the flap 9 in the aforementioned first combination state can be inserted between the two clamps 2 along the front-to-back direction, and the cover body 92 of the flap 9 can be synchronously plugged with the flap mold 5. When the flap mold 5 is driven to move upward to the flap unloading position, the flap mold 5 drives the cover body 92 to move upward, so that the cover body 92 and the seat body 91 are separated from each other. When the flap mold 5 drives the cover body 92 to move downward to the return and pressing position, the cover body 92 can be pressed down onto the seat body 91 to form the aforementioned second combination state of the flap 9. The compression degree of the cover body 92 of the above-mentioned mouth cover 9 in the return compression position is higher than the compression degree of the mouth cover 9 in the loading position, so as to achieve 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 9, and have strong practicality.

[0051] During specific use, when the mouth cover mold 5 is in the loading position and the two clamps 2 are in the release state, the seat 91 of the mouth cover 9 in the first combination state is inserted between the two clamps 2 along the front-to-back direction, and the cover body 92 is inserted into the slot 511 of the mouth cover mold 5. Then the two clamps 2 are driven to switch to the clamping state by the second driver 3 to clamp the seat body 91. Then the mouth cover mold 5 is driven to move upward to the cover removal position by the first driver 31, thereby driving the cover body 92 to separate from the seat body 91. After filling is completed, the mouth cover mold 5 is driven downward to the aforementioned return and pressing position by the first driver 31 to press the cover body 92 on the seat body 91, so that the mouth cover 9 forms the aforementioned second combination state. Finally, the two clamps 2 are driven to switch to the release state by the second driver 3 to release the clamping of the seat body 91. Through the above method, the mouth cover 9 of the non-sterile bag can be automatically pulled out and pressed, so as to avoid frequent contact between the operator and the mouth cover 9, effectively reduce human pollution, save time and labor, and effectively improve the filling efficiency of the non-sterile bag.

[0052] Embodiment 2

[0053] like Figure 11-14 As shown, on the basis of the first embodiment, the mouth cover pressing and pulling device of the second embodiment adds components such as a base 6, a first support 7, and a second support 8. Among them, a guide structure 61 is processed on the base 6. The base 6 has two substrates arranged at a relative interval on the left and right. The guide structure 61 is arranged on the substrates on both sides. The guide structure 61 is a guide groove, including an upper and lower extension section 611, and an oblique extension section 612 extending from the top of the upper and lower extension section 611 to the front or rear side, and the upper and lower extension sections 611 and the oblique extension section 612 are smoothly transitioned and connected. A slide groove extending in the front and rear direction is processed on the base 6. Rollers are installed on the left and right sides of the first support 7. The rollers are inserted into the slide groove in a rolling matching manner, so that the first support 7 can be slidably installed on the base 6 forward and backward. The matching method of the above-mentioned rollers and slide grooves is common knowledge in the art. The aforementioned second support 8 is arranged below the first support 7, and a roller is installed on the second support 8 corresponding to the guide structure 61. The roller is inserted into the guide structure 61 in a sliding fit manner, so that the second support 8 can be slidably connected to the guide structure 61. The first driver 31 is fixed on the first support 7, and its driving end is connected to the second support 8. The first driver 31 is used to drive the second support 8 to move up and down to approach or move away from the first support 7. The cover mold 5 is fixed on the second support 8.

[0054] Among them, under the drive of the first driver 31, the guide structure 61 guides the flap mold 5 to move, and the second support 8 and the flap mold 5 can move back and forth in the upper and lower extension sections 611 and the oblique extension section 612 of the guide structure 61. When the flap mold 5 moves up and down in the upper and lower extension sections 611, the loading position, the cover removal position and the return and pressing position in the above-mentioned embodiment 1 can be realized to realize the removal and pressing of the cover body 92. When the flap mold 5 moves to the oblique extension section 612, and the flap mold 5 moves to the front or rear position of the flap clamping mechanism, the first support 7 moves to the front or rear side synchronously, so that the removed cover body 92 and the seat body 91 can be staggered front and back, and the space above the bag mouth of the seat body 91 is not blocked by the flap mold 5 and the cover body 92, so as to facilitate the subsequent filling operation, and the practicability is strong.
