Description

Technical Field

[0001] This utility model belongs to the technical field of bottle preform processing, and in particular relates to a sealing block installation and adjustment mechanism for a hydrogen peroxide steam sterilization device. Background Technology

[0002] During the preform production process, bottles need to be sterilized. Currently, preforms are generally produced using automated production lines, such as fully automatic rotary blow molding machines. In the sterilization process of a fully automatic rotary blow molding machine, the preforms enter the rotary unit from the preform feeding device. During rotation, compressed air is blown into the preforms by the blowing device to clean the inner wall of the preforms. A dust extraction system purifies the air in the blowing device before releasing it into the atmosphere. The dust-removed preforms are then conveyed by a star wheel device to an H2O2 steam sterilization device. After the nozzles sterilize the inner wall of the preforms, the steam is collected by an extraction device and then discharged as waste gas. The preforms sterilized by H2O2 steam are then sent to a heating machine by the star wheel device.

[0003] Existing H2O2 steam sterilization devices generally use cylinders to directly drive the movement of the sealing block (e.g.) Figure 1 As shown in the figure, the sealing block will rub against the indexing plate during use. The sealing block needs to be replaced after 3000 hours of operation. After the sealing block is worn, if the surface of the sealing block does not make good contact with the indexing plate, the hydrogen peroxide spraying pressure needs to be increased in order to meet the sterilization effect of the preform. During H2O2 steam sterilization, due to the high temperature (125℃) and high pressure (5 bar), steam may leak when passing through the sealing block and the cylinder base, which will affect the sterilization effect of hydrogen peroxide. Utility Model Content

[0004] The purpose of this invention is to solve at least one problem of the prior art and to propose a sealing block installation and adjustment mechanism for a hydrogen peroxide steam sterilization device.

[0005] To achieve the above objectives, this utility model proposes a sealing block installation and adjustment mechanism for a hydrogen peroxide steam sterilization device, comprising a bracket, a linear drive element, a mounting base, an adjustment block, and a sealing block. The linear drive element is mounted on the bracket and connected to the mounting base, driving and controlling the linear movement of the mounting base. The adjustment block is located between the sealing block and the mounting base to increase the travel of the sealing block. Sealing elements are provided between the first and second opposing surfaces of the adjustment block and the mounting base and the sealing block, respectively. The adjustment block, the mounting base, and the sealing block are connected by a screw. The inclination of the sealing block's surface away from the mounting base is adjusted by turning the screw. The sealing block is used to connect to the outer surface of the indexing plate. The sealing block, the adjustment block, and the mounting base all have channels for hydrogen peroxide steam flow. The channels of the sealing block are connected to the steam passages on the outer surface of the indexing plate.

[0006] As an optional implementation, the second surface of the adjusting block is provided with a protrusion, and the sealing element between the adjusting block and the sealing block is sleeved on the outside of the protrusion.

[0007] As an optional implementation, the seal is provided with an opening adapted to the channel and the screw.

[0008] As an optional implementation, the bottom of the bracket is provided with an adjustment waist hole. The bracket is fastened to the worktable of the steam sterilization device by bolts.

[0012] As an optional implementation, the linear drive element is an electric actuator, a pneumatic cylinder, or a hydraulic cylinder, with the movable end of the electric actuator, pneumatic cylinder, or hydraulic cylinder connected to the mounting base.

[0013] As an optional implementation, the mounting base, adjusting block, and sealing block are all symmetrically provided with mounting holes for mounting screws on both sides.

[0014] As an optional implementation, the mounting base is provided with an air hole, which is connected to the channel of the mounting base, and the air hole is connected to a hydrogen peroxide steam supply device via a pipe.

[0015] The beneficial effects of this utility model are as follows: By setting an adjustment block and a sealing element between the sealing block and the mounting base, the adjustment block can increase the movement stroke of the sealing block, thereby increasing its surface adjustment range and extending its service life. The sealing element can prevent the leakage of hydrogen peroxide vapor and ensure the sterilization effect of hydrogen peroxide vapor on the preform.

[0028] The present invention will now be described in detail with reference to the accompanying drawings.

[0029] See Figures 2 to 8 This embodiment provides a sealing block installation and adjustment mechanism for a hydrogen peroxide steam sterilization device, including a bracket 1, a linear drive element 2, a mounting base 3, an adjustment block 5, and a sealing block 4. The linear drive element 2 is mounted on the bracket 1 and connected to the mounting base 3, driving and controlling the linear movement of the mounting base 3. The adjustment block 5 is located between the sealing block 4 and the mounting base 3 to increase the travel of the sealing block 4. A sealing element 6 is provided between the first and second opposing surfaces of the adjustment block 5 and the mounting base 3 and the sealing block 4, respectively. The adjustment block 5, the mounting base 3, and the sealing block 4 are connected by a screw 31. The inclination of the end surface of the sealing block 4 away from the mounting base 3 is adjusted by turning the screw 31. The sealing block 4 is used to connect to the outer side of the indexing plate 7. The sealing block 4, the adjustment block 5, and the mounting base 3 all have channels for hydrogen peroxide steam to flow inside. The channels of the sealing block 4 are connected to the steam passage holes 71 on the outer side of the indexing plate 7.

[0030] The first surface and the second surface of the adjusting block 5 are the end surface of the adjusting block near the mounting base 3 and the end surface of the adjusting block near the sealing block 4, respectively.

[0031] In use, the adjusting block 5, the sealing element 6, the sealing block 4, and the mounting base 3 are connected by screws 31. The linear drive element 2 drives the mounting base 3, the adjusting block 5, and the sealing block 4 to approach the indexing plate 7 until the surface of the sealing block 4 away from the mounting base 3 contacts the outer circular surface of the indexing plate 7. Hydrogen peroxide vapor flows sequentially through the channels inside the mounting base 3, the adjusting block 5, and the sealing block 4 into the corresponding steam passage 71 on the indexing plate 7. The steam in the steam passage 71 sterilizes the corresponding preform 8 mounted on the indexing plate 7. After each sterilization, the indexing plate 7 rotates a certain angle to complete the process. All preforms 8 on the indexing plate 7 are sterilized with hydrogen peroxide steam. After a period of use, the sealing block 4 wears down due to friction with the indexing plate 7. By adjusting the length of the screws entering the sealing block 4 by turning the screws 31, and in conjunction with the linear drive element 2 driving the adjusting block 5 and the sealing block 4 to move slightly, the tilt of the end of the sealing block 4 away from the mounting base 3 can be adjusted so that the sealing block 4 can continue to contact the outer surface of the indexing plate 7. The setting of the adjusting block 5 increases the range of motion of the sealing block 4, thus extending the service life of the sealing block 4. There are at least two screws 31, which are set on both sides of the channel.

[0032] Experimental testing revealed that by adding an adjusting block 5 and a sealing element 6 between the mounting base 3 and the sealing block 4, the coverage rate of the double anode on the preform can be increased from 90% to 100%, the service life of the sealing block 4 can be increased to 6000 hours, the unit price of the sealing block 4 is 1950 yuan, and the annual cost per unit is 1950 yuan.

[0033] In this embodiment, the second surface of the adjusting block 5 is provided with a protrusion 51. The sealing element 6 between the adjusting block 5 and the sealing block 4 is sleeved on the outside of the protrusion 51. The channel of the adjusting block 5 passes through the protrusion 51. When the adjusting block 5 and the sealing block 4 are installed, the protrusion 51 is inserted into the channel of the sealing block 4. The protrusion 51 can limit the sealing element 6 to a certain extent. On the other hand, the protrusion 51 can be inserted into the channel, which can prevent gaps from appearing between the adjusting block 5 and the sealing block 4 while adjusting the sealing block 4, further ensuring that hydrogen peroxide vapor is not easily leaked.

[0034] In this embodiment, the sealing element 6 is provided with an opening that is compatible with the channel and the screw 31, which facilitates the installation of the sealing element.

[0035] In this embodiment, the sealing element 6 is a Teflon gasket.

[0036] In this embodiment, the bottom of the bracket 1 is provided with an adjustment waist hole. The bracket 1 is fastened to the worktable of the steam sterilization device by bolts, with the bolts located inside the adjustment waist hole. By adjusting the position of the bolts within the adjustment waist hole, the horizontal positions of the bracket 1, linear drive element 2, mounting base 3, adjusting block 5, and sealing block 4 are simultaneously changed. The setting of the adjustment waist hole facilitates fine-tuning of the bracket's position in the same direction as the linear drive element's movement, better meeting the position adjustment and installation requirements of the sealing block.

[0037] In this embodiment, the adjusting block 5 is a 304 metal block or a 316 metal block, and the first surface of the adjusting block 5 is provided with a sealing groove for installing the sealing element 6, which facilitates the installation of the sealing element.

[0038] In this embodiment, the sealing block 4 is a polytetrafluoroethylene sealing block. An arc-shaped groove is provided at one end of the sealing block 4 near the indexing plate 7. The arc-shaped groove allows it to fit and contact the indexing plate, reducing friction.

[0039] In this embodiment, the linear drive element 2 is an electric push rod, a pneumatic cylinder, or a hydraulic cylinder, and the movable end of the electric push rod, pneumatic cylinder, or hydraulic cylinder is connected to the mounting base 3.

[0040] In this embodiment, mounting holes for mounting screws are symmetrically provided on both sides of the mounting base 3, adjusting block 5, and sealing block 4. The mounting holes of the sealing block 4 are threaded holes, while the mounting holes in the adjusting block 5 and mounting base 3 are smooth holes.

[0041] In this embodiment, the mounting base 3 is provided with an air hole for hydrogen peroxide vapor to pass through. The air hole is connected to the channel of the mounting base 3 and is connected to the hydrogen peroxide vapor supply device by a pipe.

[0042] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
