Description

Technical Field

[0001] The present application relates to the technical field of gasket installation, and in particular to a sealing gasket processing device. Background Art

[0002] Bottled food needs to be sealed after processing, and sealing gaskets are usually used for sealing. Since the traditional sealing gasket has a three-layer structure of paper-aluminum foil-film, the paper faces outward and the film faces inward. The sealing gaskets are differentiated according to actual use. Some are glued to the bottle mouth and some are glued to the bottle cap. Among them, the sealing gaskets glued to the bottle cap need to be glued to the bottle cap before they can be glued to the bottle cap.

[0003] In the prior art, generally glue is applied to the bottle cap and then the gasket is glued on. Since some of the glue used is hot melt glue, which is synthesized from chemical materials, it will affect food safety. If the inner wall of the bottle cap used at this time is relatively uneven or irregular, the method of first applying glue on the bottle cap may cause the hot melt glue to have a certain fluidity and may flow to the inner wall of the bottle cap before the gasket is glued to the bottle cap. At this time, if the gasket is glued again, it may overflow on the gasket, which may affect the subsequent food safety. Therefore, further improvement is needed. Summary of the invention

[0004] In order to reduce the possibility of overflow of the applied glue, the present application provides a sealing gasket processing equipment.

[0005] The present application provides a sealing gasket processing device, which adopts the following technical solution: A sealing gasket processing equipment comprises a workbench, a rotating platform rotatably connected to the workbench, a feeding device arranged on the workbench to transport the gasket to the rotating platform, a gluing device arranged on the workbench to gluing the gasket, a cooling device arranged on the workbench to cool the gasket after gluing, and a discharging device arranged on the workbench to transport the cooled gasket; the upper surface of the rotating platform has an arc-shaped carrying notch, the carrying notch extends to the outer peripheral wall of the rotating platform, and a plurality of carrying notches are arranged along the axis of the rotating platform, the feeding device is used to place the gasket in the carrying notch, a chamber is arranged in the rotating platform, the upper surface of the rotating platform located at the carrying notch is provided with an adsorption hole connected to the chamber, and the rotating platform is used to make the chamber a negative pressure component in a negative pressure state.

[0006] By adopting the above technical scheme, the gasket is first transported to the carrying gap for initial positioning through the feeding device, and then the negative pressure component is started to make the chamber in a negative pressure state, so that the gasket is adsorbed on the rotating platform for repositioning, and then the glue dispensing device is used to dispense glue on the gasket. Since a number of carrying gaps are provided, as the rotating platform rotates to drive a number of gaskets that have been dispensed with glue, they are cooled by the cooling device for a certain period of time and then discharged by the discharging device. At this time, since the outer layer of the glue has a certain degree of solidification or is completely solidified, a layer of adhesive layer is formed, and the hot melt adhesive is not easy to flow again, so that when it is hot-pressed and bonded to the bottle cap after the discharging device, the possibility of overflow of the applied glue can be reduced. The method of hot-pressing and bonding between the gasket and the inner wall of the bottle cap after dispensing glue on the gasket is relatively suitable for some bottle caps with relatively uneven or irregular inner walls.

[0007] Preferably, the glue dispensing device dispenses glue at a distance of 5-10 mm from the edge of the gasket, and the glue dispensing thickness on the gasket is less than 1 mm.

[0008] By adopting the above technical solution, since the hot melt adhesive flowing out from the dispensing head has a certain fluidity, if it is too close to the edge of the gasket, the hot melt adhesive may flow to the edge of the gasket due to its own fluidity, and there is a possibility of glue overflow in the subsequent bonding process with the bottle cap. In this regard, by dispensing glue at a distance of 5-10 mm from the edge of the gasket, and the glue dispensing thickness is less than 1 mm, the possibility of glue overflow when it is too close to the edge of the gasket can be reduced, thereby reducing the possibility that the odor emitted by the overflowing hot melt adhesive will remain in the bottle when the gasket is installed on the bottle cap and then installed on the corresponding bottle body.

[0009] Preferably, the cooling device includes a cover body and a delivery pipe fixedly installed in the cover body to deliver cold air into the cover body. The cover body is arranged in an arc shape around the axis of the rotating platform. The two long sides of the cover body are respectively arranged on the upper surface of the rotating platform and the workbench, and the two short sides of the cover body are provided with a second groove for the rotating platform to rotate through.

[0010] By adopting the above technical solution, as the rotating platform rotates, the gasket after dispensing glue is passed through the second groove on one side to enter the cover body, and heat exchange is performed between cold air and the hot melt adhesive so that the surface of the hot melt adhesive solidifies to reduce the flow of the hot melt adhesive, thereby facilitating subsequent hot pressing bonding between the gasket and the bottle cap.

[0011] Preferably, the rotating platform is a first heat conduction plate, and the cooling device includes a first heat conduction plate having an inner cavity, an input pipe arranged at one end of the first heat conduction plate for conveying a medium with a lower temperature into the inner cavity, and an output pipe for outputting the medium after heat exchange, and the first heat conduction plate is arranged on the surface of the rotating platform close to the rotating platform.

[0012] By adopting the above technical solution, since the rotating platform is the first heat conducting plate, the heat after the glue is dispensed on the gasket passes through the gasket, and as the first heat conducting plate transfers the heat, it is transferred to the contact surface between the first heat conducting plate and the first cold conducting plate to perform heat exchange, so that the hot melt adhesive solidifies or solidifies. As the heat exchange is carried out, the heat is transferred to the cold medium to perform heat exchange, at this time, the cold medium is continuously input through the input pipe, and the medium after heat exchange is output through the output pipe.

[0013] Preferably, the rotating platform specifically includes a first plate body, a second plate body arranged on the first plate body, a rotating plate rotatably connected to the first plate body, and a first driving member for driving the rotating plate to rotate, the carrying notch is arranged on the second plate body and extends to the upper surface of the first plate body, the chamber is arranged in the rotating plate, and the adsorption hole is arranged on the upper surface of the rotating plate; the first cooling plate is arranged on the lower surface of the rotating plate, two rotating plates are arranged in one carrying notch, and the rotating plate is arranged in the carrying notch, and the two rotating plates located in one carrying notch are symmetrically arranged along the axis of the plate body, and can rotate in a direction close to or away from each other under the drive of the first driving member.

[0014] By adopting the above technical solution, the gasket is conveyed to the carrying gap through the feeding device. After the glue dispensing device dispenses glue on the gasket, it should be noted that glue can be dispensed on both gaskets on the two rotating plates located in a carrying gap, or glue can be dispensed on one of the gaskets. The first driving member is started to make the two rotating plates rotate along the axis of the plate body in a direction close to each other, so as to drive the two gaskets to abut against each other. Under the extrusion force after the abutment, the glue on the two gaskets is squeezed and flattened, so that the hot melt adhesive is more evenly distributed on the gasket, so as to improve the contact surface with the first heat conduction plate and the outside world, so as to accelerate the curing effect of the hot melt adhesive.

[0015] After extrusion, the first driving member is started again to drive the two abutting gaskets to separate. It should be noted that the separation should be performed when the hot melt adhesive away from the gasket is still in a certain molten state to reduce the possibility of difficulty in separation after complete solidification.

[0016] Preferably, the cooling device further comprises a second heat conducting plate arranged between the two rotating plates, the second heat conducting plate is arranged vertically, and the second heat conducting plate is a non-stick plate.

[0017] By adopting the above technical solution, a second heat conducting plate is provided. Since the second heat conducting plate is provided between the two rotating plates, when the first driving member is started to drive the two rotating plates to rotate in a direction approaching each other, the gaskets located on the two rotating plates are moved toward the second heat conducting plate respectively and abut against the second heat conducting plate. The heat dispensed on the gaskets is conducted away through the second heat conducting plate, and the hot melt adhesive on the two gaskets can be squeezed and flattened, and the curing of the hot melt adhesive can be further accelerated.

[0018] In this regard, in order to reduce adhesion to the second heat conducting plate after curing, the second heat conducting plate is configured as a non-stick plate.

[0019] Preferably, the cooling device comprises a second driving member for driving the second heat conducting plate to rotate along its own axis.

[0020] By adopting the above technical solution, by providing a second driving member for driving the second heat conducting plate to rotate along its own axis, the solidified adhesive layer can be separated along the rotation direction of the rotating plate while giving radial rotation to the rotating plate under the premise that the first driving member drives the rotating plate to rotate, so as to further accelerate the separation of the adhesive layer.

[0021] Preferably, the second driving member includes a rack disposed on the outer peripheral wall of the second heat conducting plate, a gear meshed with the rack, and a driving motor driving the gear to rotate.

[0022] By adopting the above technical solution, the driving motor drives the driving gear to rotate, thereby driving the rack to rotate, so as to achieve rotation in the radial direction and give the bonding layer a little torsional force.

[0023] In summary, this application has the following beneficial effects: First, the gasket is transported to the carrying notch for initial positioning through the feeding device, and then the first air pump is started to bring the chamber into a negative pressure state, so that the gasket is adsorbed on the rotating platform for repositioning, and then glue is dispensed on the gasket through the glue dispensing device. Since a number of carrying notches are provided, as the rotating platform rotates, a number of gaskets that have been glued are driven to cool for a certain period of time and then discharged by the discharging device. At this time, since the outer layer of the glue is solidified to a certain extent and is not easy to flow, the possibility of overflow of the applied glue can be reduced when hot-pressing and bonding with the bottle cap, and it is relatively suitable for some bottle caps with relatively uneven or irregular inner walls.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-8 , further details of this application are given.

[0027] The embodiment of the present application discloses a sealing gasket processing device.

[0028] Embodiment 1: A sealing gasket processing equipment, referring to Figure 1 , Figure 2, including a workbench 1, a rotating platform 2 rotatably connected to the workbench 1, a feeding device 3 arranged on the workbench 1 to transport the gasket to the rotating platform 2, a gluing device 4 arranged on the workbench 1 to gluing the gasket, a cooling device 5 arranged on the workbench 1 to cool the gasket after gluing, and a discharging device 6 arranged on the workbench 1 to transport the cooled gasket.

[0029] The lower surface of the workbench 1 is fixedly connected with a frame 11 for support, and the upper surface of the workbench 1 is provided with a rotation groove 12 for the rotation of the rotating platform 2. The rotation of the rotating platform 2 is specifically driven by a driving assembly 7, which specifically includes a transmission shaft 71 rotatably passing through the workbench 1, a driven gear 72 coaxially sleeved on the outer peripheral wall of the transmission shaft 71, a driving gear 73 meshed with the driven gear 72, and a first driving motor 74 driving the driving gear 73 to rotate. The axis of the transmission shaft 71 is parallel to the axis of the workbench 1, and the upper end of the transmission shaft 71 is fixedly connected to the upper surface of the rotating platform 2.

[0030] Reference Figure 1 , Figure 3 In this embodiment, the upper surface of the rotating platform 2 is protruding from the upper surface of the workbench 1. The rotating platform 2 specifically includes a first plate body 21 fixedly connected to the transmission shaft 71 and a second plate body 22 fixedly connected to the upper surface of the plate body. The upper surface of the first plate body 21 is flush with the upper surface of the workbench 1. In this embodiment, the outer diameter of the first plate body 21 is greater than the outer diameter of the second plate body 22. The upper surface of the second plate body 22 is penetrated by a carrying notch 23 in an arc shape. The carrying notch 23 extends to the outer peripheral wall of the rotating platform 2. The carrying notch 23 is specifically semicircular. There are several carrying notches 23 along the axis of the rotating platform 2. A gasket is arranged in the carrying notch 23. A chamber 24 is arranged in the first plate body 21. The upper surface of the first plate body 21 located at the carrying notch 23 is provided with several adsorption holes 25 connected to the chamber 24.

[0031] In this embodiment, a negative pressure assembly 26 for making the chamber 24 in a negative pressure state is provided on the rotating platform 2, and the negative pressure assembly 26 includes an air pipe 261 connected to the chamber 24 and a first air pump 262 connected to the air pipe 261. For the connection between the air pipe 261 and the chamber 24, in this embodiment, an air delivery channel 711 is provided through the lower surface of the transmission shaft 71 along its own axis, and one end of the air pipe 261 away from the first air pump 262 is rotatably connected to the lower surface of the transmission shaft 71, and the air delivery channel 711 is connected to the chamber 24. Among them, the first air pump 262 is fixedly connected to the lower surface of the workbench 1.

[0032] The feeding device 3 includes a bracket 31 fixedly connected to the upper surface of the workbench 1, a base 32 fixedly connected to the upper surface of the bracket 31, a plurality of limit rods 33 fixedly connected to the upper surface of the base 32 and spaced around the axis of the base 32, a fixing plate 34 fixedly connected to the upper surface of the workbench 1, a first cylinder 35 fixedly connected to the upper surface of the workbench 1, and a push plate fixed to the piston rod of the first cylinder 35. The plurality of limit rods 33 form a placement cavity for placing gaskets for storage, the base 32 is provided with a first through groove for gaskets to pass through along its height direction, the spacing between the base 32 and the workbench 1 is slightly larger than the thickness of the gasket itself, and the push plate is used to push the gasket to the carrying gap 23 for positioning.

[0033] Among them, the glue dispensing device 4 can be specifically a glue dispensing machine. Since the glue dispensing machine is a conventional equipment in the prior art, it will not be described in detail here. However, it should be noted that the glue dispensing device 4 dispenses glue at a distance of 5-10 mm wide from the edge of the gasket, and the glue dispensing thickness on the gasket is less than 1 mm. The specific glue dispensing thickness can be 5-7 threads to reduce the possibility of glue overflow during the glue dispensing process, thereby reducing the possibility of odor emitted by the overflowing hot melt adhesive remaining in the bottle when the gasket is installed on the bottle cap and then installed on the corresponding bottle body.

[0034] The cooling device 5 includes a cover 51, a delivery pipe 52 fixedly arranged in the cover 51 to deliver cold air into the cover 51, a second air pump 53 fixedly connected to the air delivery pipe 261, and a refrigeration chamber 54 for producing cold air. In this embodiment, the cover 51 is arranged in an arc shape around the axis of the rotating platform 2, and the two long sides of the cover 51 are respectively arranged on the upper surface of the rotating platform 2 and the workbench 1. The side of the cover 51 arranged on the upper surface of the workbench 1 is fixedly connected to the workbench 1, and the two short sides of the cover 51 are provided with a second through groove 511 for the rotating platform 2 to rotate through. The air delivery pipe 261 is arranged close to the dispensing head, and the air is blown toward the top of the cover 51 to reduce the possibility of displacement of the gasket when it is blown directly to the gasket. Among them, the second air pump 53 is fixedly connected to the lower surface of the workbench 1, and the air inlet end of the second air pump 53 is fixedly penetrated into the refrigeration chamber 54, and the refrigeration chamber 54 is fixedly connected to the lower surface of the workbench 1. Since the refrigeration chamber 54 is a prior art, it will not be described in detail here.

[0035] The discharging device 6 specifically includes a guide plate 61 disposed on the upper surface of the workbench 1 and a conveyor belt 62 disposed on the lower surface of the workbench 1. The length direction of the guide plate 61 is inclined to the axis of the rotating platform 2. The width of the guide plate 61 itself gradually decreases toward the rotating platform 2. The side wall of the guide plate 61 close to the cover body 51 is provided with a first guide surface 611 in an arc shape. The upper surface of the workbench is provided with a drop hole 13 for the gasket to drop. The drop hole 13 is located above the conveyor belt 62 for conveying the processed gasket. It should be noted that since the gasket is adsorbed on the rotating platform 2 due to negative pressure, when guided by the first guide surface 611, the gasket may wrinkle during the detachment process. To this end, the first guide surface 611 is arranged in an arc shape along the thickness direction of the guide plate 61 toward the workbench 1, that is, it has a second guide surface 612, so that the gasket is detached from the rotating platform 2 under the guidance of the second guide surface 612, and is pushed toward the drop hole 13 by the rotation force of the rotating platform 2. As several subsequent gaskets are detached, they are pushed between adjacent gaskets and fall from the drop hole 13 onto the conveyor belt 62 for transportation.

[0036] The implementation principle of a sealing gasket processing equipment in an embodiment of the present application is as follows: first, the gasket is transported to the carrying gap 23 by the feeding device 3 for initial positioning, and then the negative pressure component 26 is started to make the chamber 24 in a negative pressure state, so as to adsorb the gasket on the rotating platform 2 for repositioning, and then the glue dispensing device 4 is used to dispense glue on the gasket. Since a plurality of carrying gaps 23 are provided, as the rotating platform 2 rotates to drive a plurality of gaskets that have been dispensed with glue, after being cooled for a certain period of time by the cooling device 5, the gasket is discharged by the discharging device 6. At this time, since the outer layer of the glue has a certain degree of solidification or is completely solidified, a layer of adhesive layer is formed, and the hot melt adhesive is not easy to flow again, so that when it is hot-pressed and bonded to the bottle cap after the discharging device 6, the possibility of overflow of the applied glue can be reduced. The method of hot-pressing and bonding the gasket to the inner wall of the bottle cap after dispensing glue on the gasket is relatively suitable for some bottle caps with relatively uneven or irregular inner walls.

[0037] Embodiment 2: Reference Figure 4 The difference from Example 1 is that, in this embodiment, the rotating platform 2 is a first heat conducting plate, which can be used to conduct heat to the hot melt adhesive on the gasket to accelerate the solidification of the gasket.

In this embodiment, the rotating plate 27 is specifically shown as a circular plate. Since the rotating plate 27 can move in a direction close to or away from each other under the drive of the first driving member 271, an anti-slip strip can be arranged in the direction of the rotating plate 27 close to the mounting groove 211, which is specifically arranged according to the requirements to prevent slipping.

[0040] In this embodiment, for the first driving member 271, specifically the second cylinder, the first plate body 21 is located in the carrying notch 23 and is provided with a mounting groove 211 for installing the second cylinder.

The length direction of the second cylinder is inclined to the length direction of the mounting groove 211 in the vertical direction. The piston rod of the second cylinder is hinged to the lower surface of the rotating plate 27. Two symmetrically arranged mounting grooves 211 are arranged in a carrying notch 23, and the rotating plate 27 is rotatably connected along the edge of the mounting groove 211.

[0041] As for the negative pressure state in the chamber 24 at this time, in this embodiment, a bronchus 261 connected to the trachea 261 is specifically provided, and the bronchus 261 is a telescopic hose, and the bronchus 261 is fixedly penetrated through the first cold conducting plate 55 to communicate with the chamber 24. As for the medium with a lower temperature in the first cold conducting plate 55, in this embodiment, the number of the input pipes 56 and the output pipes 57 is set to correspond to the number of the first cold conducting plates 55, and the local pipelines of the input pipes 56 and the output pipes 57 located in the installation groove 211 are all telescopic hoses to adapt to the rotation change of the second cylinder when pushing the rotating plate 27 to be vertically set.
