Description

Technical Field

[0001] The invention relates to the technical field of dust prevention of a vial mouth, and in particular to a dust prevention structure of a vial mouth. Background Art

[0002] A vial, also known as a borosilicate glass or soda-lime glass tube (molded) injection bottle, is a small bottle sealed with a rubber stopper and an aluminum-plastic combination cover. In the early days, penicillin was mostly contained in it, hence the name vial.

[0003] In the filling production line, the vials need to go through the bottle dust removal step before filling. However, the dust removal equipment and the filling equipment have a certain moving distance, so after dust cleaning, the bottle needs to be transported to the filling equipment by a conveyor belt. At this time, the mouth of the vial will be exposed to the air, so a small amount of dust will enter the vial, resulting in residual dust inside. The dust will have different degrees of impact on the injection. Summary of the invention

[0004] The present invention provides a dust-proof structure for a vial mouth to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A bottle mouth sealing mechanism, the bottle mouth sealing mechanism is installed on the supporting mechanism, the bottle mouth sealing mechanism comprises a rubber belt, the inner wall of the rubber belt is provided with a groove, and an air bag belt is fixed to the bottom of the rubber belt;

[0009] A driving mechanism, which is installed on the top of the bottle mouth sealing mechanism and drives the bottle mouth sealing mechanism to operate;

[0010] A dust collecting mechanism, the dust collecting mechanism is installed outside the rubber belt and the airbag belt, and the dust collecting mechanism includes a negative ion fan;

[0011] A friction mechanism, the friction mechanism is mounted on the support mechanism, the friction mechanism comprises a belt 1, a friction belt is fixed to the outside of the belt 1, and the friction belt is in contact with the airbag belt;

[0012] A bottle body stabilizing mechanism is installed at the bottom of the bottle mouth closing mechanism, and the bottle body stabilizing mechanism includes a second belt, and a flexible material is fixed to the outer wall of the second belt. The flexible material is located at the top of the conveyor belt and occupies two-fifths of the transverse length of the conveyor belt. The bottle body occupies three-fifths of the transverse length of the conveyor belt, so the flexible material will squeeze and wrap one side of the bottle body.

[0013] Furthermore, the supporting mechanism includes two L-shaped frames fixed on one side of the conveyor belt, and a top plate is fixed between the two L-shaped frames.

[0014] Furthermore, the bottle mouth sealing mechanism also includes two rotating shafts 1 rotatably connected to the inside of the top plate, a transmission disk is fixed to the outside of the rotating shaft 1, and the two transmission disks are sleeved inside the groove. The top bottle mouth of the bottle body contacts the bottom of the airbag belt. Because the bottom of the airbag is higher than the top of the bottle body and because the airbag is relatively soft, the bottle mouth will be wrapped by pressure to seal the bottle mouth after dust removal. The purpose of the closure is to prevent dust from entering the inside of the bottle body again on the way to the filling equipment.

[0019] Furthermore, a controller is installed on one side of the conveyor belt, and the controller is electrically connected to the conveyor belt, the motor and the negative ion blower.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0038] A supporting mechanism 2, wherein the supporting mechanism 2 is installed at one side of the conveyor belt 1;

[0039] The bottle mouth sealing mechanism 3 is installed on the supporting mechanism 2, and the bottle mouth sealing mechanism 3 includes a rubber belt 33, the inner wall of the rubber belt 33 is provided with a groove 34, and the bottom of the rubber belt 33 is fixed with an air bag belt 35;

[0040] A driving mechanism 4, which is mounted on the top of the bottle mouth sealing mechanism 3, and drives the bottle mouth sealing mechanism 3 to operate;

[0041] A dust collecting mechanism 7, which is installed outside the rubber belt 33 and the airbag belt 35, and includes a negative ion fan 72;

[0042] The friction mechanism 5 is mounted on the supporting mechanism 2. The friction mechanism 5 includes a belt 58. A friction belt 59 is fixed to the outside of the belt 58. The friction belt 59 is in contact with the airbag belt 35.

[0043] The bottle body stabilizing mechanism 6 is installed at the bottom of the bottle mouth sealing mechanism 3. The bottle body stabilizing mechanism 6 includes a belt 2 68. A flexible material 69 is fixed to the outer wall of the belt 2 68. The flexible material is located at the top of the conveyor belt and occupies two-fifths of the transverse length of the conveyor belt. The bottle body occupies three-fifths of the transverse length of the conveyor belt, so the flexible material will squeeze and wrap one side of the bottle body.

[0044] The support mechanism 2 includes two L-shaped frames 21 fixed to one side of the conveyor belt 1, and a top plate 22 is fixed between the two L-shaped frames 21;

[0045] The bottle mouth closing mechanism 3 also includes two rotating shafts 31 rotatably connected to the inside of the top plate 22, and a transmission disk 32 is fixed to the outside of the rotating shaft 31. The two transmission disks 32 are sleeved inside the groove 34. The top bottle mouth of the bottle body contacts the bottom of the airbag belt 35. Because the bottom of the airbag is higher than the top of the bottle body, and because the airbag is relatively soft, the bottle mouth will be wrapped by pressure to close the bottle mouth after dust removal. The purpose of closing is to prevent dust from entering the bottle body again on the way to the filling equipment. The bottle mouth closing mechanism blocks the bottle mouth of the bottle body that has just been cleaned to prevent dust from entering the bottle mouth during movement.

[0047] The dust collecting mechanism 7 also includes a dust collecting box 71 sleeved on the outside of the airbag belt 35 and the friction belt 59, an air outlet pipe 73 is installed at the bottom of the dust collecting box 71, and a negative ion blower 72 is installed on the top of the dust collecting box 71. Two connecting plates are fixed on the top of the dust collecting box 71, and the connecting plates are fixedly connected to the top plate 22. After the airbag belt 35 with dust enters the interior of the dust collecting box 71, the gas blown by the negative ion blower 72 blows off the dust adsorbed on the surface of the airbag belt 35, and then is discharged from the air outlet pipe 73. The dust collecting mechanism removes static electricity by adsorbing the surface of the airbag belt in the dust collecting box 71, so that the dust falls off and is discharged by wind force;

[0048] The friction mechanism 5 also includes a second rotating shaft 51 rotatably connected to the bottom of the top plate 22, a rubber disc 52 is fixed to the outside of the second rotating shaft 51, one side of the rubber disc 52 is in contact with the inner wall of the rubber belt 33, a pulley 1 53 is fixed to the outside of the second rotating shaft 51, and two third rotating shafts 54 are rotatably connected to the bottom of the top plate 22, a pulley 2 55 is fixed to the outside of the third rotating shaft 54, a belt 3 56 is connected to the outside of the pulley 2 55 and the pulley 1 53, a pulley 3 57 is fixed to the outside of the third rotating shaft 54, and a belt 1 58 is connected to the outside of the two pulleys 3 57, and the belt 1 58 and the friction belt 59 are opposite to the direction of the rubber belt 33. The friction belt 59 and the airbag belt 35 rub to generate static electricity, and the static electricity on the friction belt 59 will generate suction for the dust on the top and outer wall of the bottle body, so as to further clean the bottle body. The friction mechanism generates static electricity by rubbing the surface of the airbag belt, thereby absorbing the dust on the surface and the bottle mouth of the bottle body, so as to further clean the bottle body and reduce the dust residue in the bottle body.

[0049] The bottle body stabilizing mechanism 6 also includes two mounting plates 61 fixed on one side of the conveyor belt 1, the two mounting plates 61 are internally rotatably connected with a rotating shaft 4 62 and a rotating shaft 5 64, the top of the rotating shaft 4 62 is fixedly connected to the bottom of the transmission disk 32, the bottom end of the rotating shaft 4 62 is fixed with a pulley 4 63, the bottom end of the rotating shaft 5 64 is fixed with a pulley 5 65, the external transmission of the pulley 4 63 and the pulley 5 65 is connected with a belt 4 66, the top of the rotating shaft 5 64 is fixed with a pulley 67, and the belt 2 68 is transmission-connected to the outside of the two pulleys 67, and the flexible material 69 is located The top of the conveyor belt 1, after being located on the conveyor belt 1, one side of the bottle body that continues to move will contact one side of the flexible material 69, and the flexible material 69 will squeeze the bottle body against the side plate of the conveyor belt 1, limiting the position of the bottle body to prevent the top of the bottle body from tipping over when it contacts the bottom of the airbag belt 35. The side plates on both sides of the conveyor belt have different heights, and the height of the side plate below the flexible material is lower than the height of the side plate on one side of the flexible material, to prevent the flexible material from squeezing out the bottle body and tilting it when both sides are the same height. The bottle body stabilizing mechanism fixes the bottle body that enters the conveyor belt to prevent the top of the bottle body from tilting when it contacts the airbag belt.

[0050] A controller is installed on one side of the conveyor belt 1 , and the controller is electrically connected to the conveyor belt 1 , the motor 42 and the negative ion blower 72 .

[0051] Working principle: The controller controls the transmission belt 1, the negative ion fan 72 and the motor 42 to operate. The motor 42 drives the shaft 1 31, the transmission disc 32 and the shaft 4 62 to rotate. The rotation of the transmission disc 32 drives the rubber belt 33 to rotate due to the friction between the transmission disc 32 and the groove 34. The rotation of the rubber belt 33 drives the airbag belt 35 to rotate. The rotation of the shaft 4 62 drives the shaft 5 64 to rotate through the pulley 4 63, the belt 4 66 and the pulley 5 65. The shaft 5 64 drives the pulley 6 67 to rotate. The pulley 6 67 drives the belt 2 68 and the flexible material 69. The bottle body after dust removal enters the conveyor belt 1 from one end of the conveyor belt 1, and after being on the conveyor belt 1, one side of the bottle body will contact with one side of the flexible material 69, and the flexible material 69 will squeeze the bottle body against the side plate of the conveyor belt 1, and limit the bottle body to prevent the top of the bottle body from tipping over when it contacts the bottom of the airbag belt 35. If the bottle body continues to move, the top of the bottle body will contact with the bottom of the airbag belt 35, because the bottom of the airbag is higher than the top of the bottle body, and because the airbag is relatively soft. Therefore, the bottle mouth will be wrapped and sealed due to pressure, and the purpose of sealing is to prevent dust from entering the bottle body again on the way to the filling equipment, and then move from one end of the conveyor belt 1 to the other end, move out of the conveyor belt 1 and enter the filling equipment. During the movement of the rubber belt 33, the rubber disc 52 will be driven to rotate by friction, and the rubber disc 52 will drive the rotating shaft 2 51 and the pulley 1 53 to rotate. The pulley 1 53 drives the pulley 2 55 and one of the rotating shafts 3 54 to rotate through the belt 3 56, and one of the rotating shafts 3 54 rotates through the pulley 3 57 and belt one 58 drive another pulley three 57 and shaft three 54 to rotate, and belt one 58 drives friction belt 59 to rotate. At this time, belt one 58 and friction belt 59 are opposite to the direction of the rubber belt 33. The friction between friction belt 59 and air bag belt 35 generates static electricity. The static electricity on friction belt 59 will generate suction for dust on the top and outer wall of the bottle body, so as to further clean the bottle body. After the air bag belt 35 with dust enters the dust collecting box 71, the gas blown out by negative ion blower 72 will blow away the dust adsorbed on the surface of the air bag belt 35, and then be discharged from the air outlet pipe 73.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
