The sealing machine is fixedly connected to one side of the upper surface of the base, and the rubber feeding hose is fixedly connected below the surface of the sealing machine. The two semi-turbines are combined to drive the sealing plug and the cleaning airbag to be inserted into the outlet of the rubber feeding hose.

Description

Technical Field

[0001] The invention relates to the field of double-layer plastic cup sealing, in particular to a double-layer plastic vacuum cup sealing device. Background Art

[0002] In the prior art, for the sealing of double-layer plastic vacuum cups, the double-layer cups are usually connected and sealed by gluing, and the glue is squeezed by injection equipment to complete the sealing operation of the double-layer plastic vacuum cups. However, when the existing sealing equipment performs the sealing operation on the double-layer plastic vacuum cups, there are often tiny dust, fibers and other impurities in the environment where the glue extrusion head is located. These impurities will adhere to the outside of the glue extrusion head with the flow of air or contact with other objects during the operation. At the same time, after the glue is squeezed out, some of the glue will remain and gradually dry and solidify, and will also adhere to the outside of the glue extrusion head. These residues will mix with the new glue, affecting The purity and quality of the glue, residues and impurities can also cause the channel or nozzle of the glue injection head to be blocked, affecting the normal flow and injection of glue, and even causing equipment failure. Moreover, due to the lack of sealing measures, the glue extrusion head is also easily contaminated when idle, increasing the difficulty and cost of cleaning and maintenance. In addition, the existing structure is not perfect in the protection and management of the glue extrusion head, and it needs to be shut down for operation, which affects the overall continuity and utilization of the equipment to a certain extent, and cannot meet the needs of efficient and stable production. It greatly limits the further optimization and development of the double-layer plastic vacuum cup sealing process, and is not conducive to improving the overall quality and production efficiency of the product.

[0003] For example, the Chinese invention patent (publication number: CN114670397A) discloses an "injection nozzle for a two-color injection molding machine that prevents injection molding liquid from leaking". Its specification discloses: 1. It is generally not convenient to clean the injection port of existing high-precision CNC injection molding machines. After the injection molding is completed, some injection molding materials still remain on the injection molding port. If they are not cleaned in time, these injection molding materials are easy to condense on the injection molding port, causing the injection molding port to be blocked, affecting the normal use of the injection molding machine; 2. It is not convenient to remove bubbles in existing high-precision CNC injection molding machines. After the injection molding is completed, the surface of the plastic product is easy to come into contact with the air to generate bubbles, affecting the quality of the injection molded product; the above patents can prove the defects of the existing technology.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the scheme of this application:

[0021] 1. In order to solve the problem that it is inconvenient to clean and seal the rubber head when the double-layer cup is squeezed and sealed in the prior art, the present application drives the sealing plug and the cleaning airbag to be inserted into the rubber feeding hose by merging the two semi-turbines, and then the outlet of the rubber feeding hose is blocked by the sealing plug and the cleaning airbag. When the rubber feeding hose moves down, the double-layer plastic vacuum cup needs to be sealed. At the same time, the semi-turbine can rotate so that the sealing plug, the cleaning airbag and the cleaning plate can cooperate to clean the rubber extrusion port of the rubber feeding hose. The cleaning can be performed after the rubber extrusion is completed, thereby preventing the residual glue from solidifying and drying to affect the normal glue discharge performance of the rubber feeding hose, maintaining a good glue extrusion effect, preventing pollution, and preventing impurities, dust, etc. from adhering to the rubber head and then contaminating the glue used subsequently, thereby ensuring the quality of the glue;

[0022] 2. In order to solve the problems in the prior art that when double-layer plastic cups are sealed, residual glue is left on the surface, resulting in poor sealing quality, and the glue on the surface of the double-layer plastic cups is unevenly applied, the present application sets two first connecting plates with connecting rods at different heights, so that the glue roller spreads the glue flat during the rotation of the cup, and then the glue after spreading is scraped off when passing through the scraper, so that the glue is spread horizontally, avoiding unevenness on the surface, resulting in poor sealing effect of the glue;

[0023] 3. The groove, connecting rod, second connecting plate and piston block cooperate with each other, so that before the glue is supplied to the rubber hose, the second mounting plate is driven by the piston block on one side to fit and wipe the surface of the double-layer cup, so as to pre-clean the surface of the double-layer cup and avoid the adhesion of impurities on the surface of the double-layer cup. After the glue is supplied, when the double-layer cups fit together, the second connecting plate and the piston block can be driven downward by the piston block on the other side, so that the glue roller and the scraper can scrape the excess glue on the surface of the double-layer cup. At this time, the two second connecting plates and the piston block can cooperate in the groove to always present an up-and-down staggered state, which solves the problem of inconvenience in wiping and pre-treating the double-layer cup when it is squeezed and sealed in the prior art;

[0024] 4. The two air guide tubes are arranged to be connected to the grooves in an up-and-down staggered manner, so that the fixed block can apply pressure to the bellows when unfolded, so that the air in the bellows can be transmitted to the air guide tube for transportation. At this time, the air guide tube can transmit the air to the groove, and because the two air guide tubes are respectively located at the upper and lower positions of the two grooves, the air guide tubes can apply pressure through the air, ensuring that the positions of the two second connecting plates and the piston block are always in an up-and-down staggered state, realizing two working states before and after glue squeezing, improving the sealing continuity of the double-layer cup, and improving work efficiency.

[0025] 5. The limit plate is set to cooperate with the bidirectional screw, so that the bidirectional screw is rotated through the motor drive. Then, when the limit plate cancels the limit on the double-layer cup, the worm can be driven to rotate. At this time, the worm is engaged and driven to rotate with the half-turbine, so that the sealing plug, the cleaning airbag and the cleaning plate can wipe the surface of the rubber hose, thereby improving the cleaning and sealing effect of the rubber hose, and solving the problem of inconvenience in cleaning the rubber hose in the prior art.

[0044] In order to solve this technical problem, the present invention provides a double-layer plastic vacuum cup sealing device, which is applied to the glue extrusion sealing of double-layer plastic cups.

[0045] Specifically, please refer to Figure 1-Figure 3 A double-layer plastic vacuum cup sealing device comprises a base 1, a sealing machine 2, a rubber feeding hose 3 and a placing rack 4. The sealing machine 2 is fixedly connected to one side of the upper surface of the base 1, the rubber feeding hose 3 is fixedly connected below the surface of the sealing machine 2, the placing rack 4 is slidably connected to the upper surface of the base 1, a cleaning component for treating residual rubber impurities is arranged on the surface of the rubber feeding hose 3, a scraping component for avoiding the accumulation of double-layer cup glue and uneven thickness of the glue layer is arranged on the outer surface of the rubber feeding hose 3, and a limiting component for avoiding the deviation of the double-layer cup is arranged on the surface of the sealing machine 2;

A semi-turbine 8 is arranged on the lower surface of the first mounting plate 6, and a mounting groove 9 is provided on the surface of the semi-turbine 8. The fixed block 7 is located in the mounting groove 9, and a fixing rod 10 penetrating the surface of the fixed block 7 is fixedly connected in the mounting groove 9. A cleaning plate 14 is fixedly connected to the surface of the semi-turbine 8, and the cleaning plate 14 is located between the first mounting plate 6 and the facing surface of the rubber supply hose 3. A lead-out groove 15 is provided on the surface of the semi-turbine 8 and is located between the sealing plug 12 and the cleaning plate 14;

[0047] The cleaning component also includes a collecting box 16 , which is located on the lower surface of the semi-turbine 8 . The facing surfaces of the collecting box 16 and the semi-turbine 8 are fixedly connected with a magnetic plate 17 , and the semi-turbine 8 and the collecting box 16 are magnetically connected via the magnetic plate 17 .

[0048] The double-layer plastic vacuum cup sealing device provided by the present invention can firstly drive the two first mounting plates 6 to move away from each other through the sliding block of the electric slide rail 5, so that the sealing plug 12 and the cleaning air bag 13 are moved out from the outlet of the rubber supply hose 3, and the impurities brought out from the surfaces of the sealing plug 12 and the cleaning air bag 13 can flow into the collection box 16 through the outlet groove 15, and when the impurities are processed, the collection box 16 can be held and vertically pulled out to cancel the magnetic installation of the magnetic suction plate 17, and after the impurities in the collection box 16 are processed, the collection box 16 can be magnetically fixed by the magnetic suction plate 17, and then the unfolded rubber supply hose 3 can squeeze out glue to bond the double-layer bonding part of the double-layer plastic vacuum cup, and after the glue is extruded, the first mounting plates 6 can be driven to approach each other through the electric slide rail 5, so that the cleaning plate 14 is bonded to the surface of the rubber supply hose 3 to process dust and residual glue, which is beneficial to cleaning the rubber head, removing impurities and residual glue attached to the rubber head, and keeping the rubber head clean.

[0049] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0050] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0051] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0052] Example 1

[0053] Please refer to Figure 4-Figure 8A double-layer plastic vacuum cup sealing device, a control component for adapting to different working conditions and overall processing continuity is arranged on the surface of the electric slide rail 5, and the control component includes a first connecting plate 18, the first connecting plate 18 is symmetrically fixedly connected to the bottom surface of the electric slide rail 5 away from the rubber supply hose 3, a groove 19 is opened in the first connecting plate 18, a connecting rod 20 is inserted in the groove 19, the bottom end of the connecting rod 20 is fixedly connected to the second connecting plate 21, the top ends of the two connecting rods 20 are fixed with piston blocks 22 located in the groove 19, and a first return spring 2 is arranged in the groove 19 3. The bottom surface of the first connecting plate 18 is fixedly connected with a positioning plate 24. When the rubber feeding hose 3 moves downward, the positions of the two first connecting plates 18 both move downward. Since the piston block 22 is located in the groove 19 in a fitted state, the first return spring 23 supports the surface of the piston block 22. When the rubber feeding hose 3 moves downward to a suitable position, the connecting rod 20 cooperates with the support of the piston block 22 and the first return spring 23 to achieve the effect of different heights of the two connecting rods 20, which is conducive to cleaning and scraping the subsequent processing steps required for the double-layer cup, thereby improving the overall sealing and extruding quality.

[0054] By having the connecting rods 20 in the two first connecting plates 18 at different heights, the double-layer plastic cup can be pre-treated and cleaned before glue extrusion. After the glue extrusion is completed, the glue on the surface of the double-layer plastic cup can be scraped off so that the glue can be evenly spread on the surface of the double-layer plastic cup, thereby improving the overall glue supply and sealing quality.

[0055] Please refer to Figure 4-Figure 8A double-layer plastic vacuum cup sealing device, wherein the control component further comprises a positioning plate 24, the positioning plate 24 is fixedly connected to the lower surface of the first connecting plate 18, a bellows 25 is fixedly connected between the positioning plate 24 and the facing surface of the fixed block 7, a pushing plate 26 fixedly connected to the fixed block 7 is arranged in the bellows 25, and the ends of the two air guide tubes 27 away from the fixed block 7 are fixedly connected to the air guide tubes 27, and the ends of the air guide tubes 27 away from the bellows 25 are connected to the groove 19. When the half turbine 8 is unfolded after the rubber hose 3 is moved downward, the two half turbines 8 at this time move away from each other, which will cause the two fixed blocks 7 to move. When the fixed block 7 moves subsequently, it can cooperate with the pushing plate 26 to gradually pressurize the bellows 25, so that the bellows 25 can be in a compressed state. At this time, the air in the bellows 25 is squeezed by the pushing plate 26 and will be discharged from the air guide tube 27. The air is discharged, and because the air guide tube 27 is long and thin, the air that is squeezed and transmitted into the air guide tube 27 moves relatively slowly at this time, so that the gas drives the piston block 22 to move relatively slowly in the groove 19, so that when the rubber hose 3 moves downward and is in an expanded state, when the positioning plate 24 is squeezed by the fixing block 7, the air is gradually transmitted into the air guide tube 27, and then transmitted into the groove 19 through the air guide tube 27 to apply pressure to the piston block 22, so that after the glue is squeezed into the rubber hose 3, when the double-layer cup cooperates with the transmission of the placement rack 4 to rotate one circle and then fit and seal, the air guide tube 27 located above the groove 19 at this time can push the piston block 22 to move downward slowly, and after the bellows 25 is reset, the air in the groove 19 can be gradually extracted, so that the positions of the two piston blocks 22 are always distributed in different states up and down, which is conducive to the required use state of the double-layer cup.

[0056] Example 2

[0057] The double-layer plastic vacuum cup sealing device provided in Example 1 is further optimized. Specifically, Figure 4-Figure 5The invention discloses a double-layer plastic vacuum cup sealing device including a scraping assembly, wherein the scraping assembly includes a second mounting plate 28, the second mounting plate 28 is fixedly connected to the bottom surface of a second connecting plate 21 on one side, a cleaning cotton 29 is detachably connected to the surface of the second mounting plate 28, the cleaning cotton 29 is made of sponge, a glue spreading roller 30 rotatably connected to the second connecting plate 21 on the other side is arranged on the side of the cleaning cotton 29 away from the second mounting plate 28, a glue spreading roller 30 fixedly connected to the second connecting plate 21 on the other side is arranged on the surface of the glue spreading roller 30, and a scraping plate 31 fixedly connected to the second connecting plate 21 is arranged on the surface of the glue spreading roller 30. In the process of the glue feeding hose 3 moving downward, the second mounting plate 28 and the cleaning cotton 29 located below the glue spreading roller 30 and the scraping plate 31 in the initial state can preferentially contact the surface of the double-layer cup, and then the double-layer cup is driven to rotate by the placement rack 4. At this time, the cleaning cotton 29 can preferentially pre-clean the part of the double-layer cup that needs to be sealed, and at the same time, when the cleaning cotton 29 contacts the double-layer cup, the glue spreading roller 30 will be in a state of not contacting the double-layer cup. When the placing rack 4 drives the double-layer cup to rotate a second circle, the excess glue is spread on the double-layer cup for a second time, which is beneficial to level the glue and avoid uneven surfaces.

[0058] The glue roller 30 is provided to scrape the glue on the surface of the double-layer cup, so that the glue can obtain a better and more uniform sealing effect, and the scraper plate 31 lays glue on the surface of the double-layer cup for the second time, which can increase certain strength and toughness at certain key parts or weak points, making the cup more durable. For some minor unevenness, an appropriate amount of secondary glue laying can play a certain leveling role, making the surface of the cup feel smoother.

[0059] Further, such as Figure 3The double-layer plastic vacuum cup sealing device includes a limiting component, which includes an electric telescopic rod 32, which is symmetrically fixedly connected to the surface of the sealing machine 2, and the output end of the electric telescopic rod 32 is fixedly connected to the mounting frame 33, and a guide block 34 is arranged in the mounting frame 33. The two ends of the second return spring 36 are respectively fixedly connected to the mounting frame 33 and the guide block 34, and the surface of the guide block 34 is rotatably connected to a bidirectional screw 37, and the surface of the bidirectional screw 37 is threadedly connected to a limiting plate 38, and a worm 40 is fixedly connected at the center of the surface of the bidirectional screw 37, and the worm 40 is intermittently meshed with two semi-turbines 8. After the glue is squeezed out of the rubber hose 3, the semi-turbine 8 cooperates with the sealing plug 12 and the cleaning air bag 13 to be inserted into the rubber hose 3. At this time, the two half-turbines 8 are combined into a complete state. As the rubber feeding hose 3 gradually moves upward, the half-turbine 8 in the complete state can be fitted and meshed with the surface of the worm 40. After the double-layer cup rotation scraping process is completed, the limit plate 38 at this time can cancel the fit limit with the double-layer cup. At the same time, the worm 40 can mesh with the transmission half-turbine 8 to rotate on the bottom surface of the rubber feeding hose 3, so that the sealing plug 12, the cleaning airbag 13 and the cleaning plate 14 can all rotate and wipe on the surface of the rubber feeding hose 3. When the rubber hose 3 continues to move upward and gradually resets, the half-turbine 8 cancels the meshing transmission with the worm 40, and can be pushed by the guide spring 11 to slide and reset on the surface of the fixed rod 10, which is conducive to the coordinated transmission of the half-turbine 8 and is conducive to improving the cleaning effect of the rubber feeding hose 3.

[0060] The limiting plate 38 is provided to accurately limit the position of the cup, ensuring that the position of the cup is fixed during the cleaning process. At the same time, the semi-turbine 8 is driven to rotate, so that the sealing plug 12, the cleaning airbag 13, and the cleaning plate 14 can be rotated for cleaning, thereby ensuring the stable cleaning action and improving the cleaning quality. The transmission of the cleaning mechanism can be completed while the limit on the cup is cancelled, thereby realizing the synchronization of the two actions and improving work efficiency.

[0061] Example 3

[0062] The double-layer plastic vacuum cup sealing device provided in Example 1 or 2 is further optimized, specifically, as follows: Figure 7As shown, the surface of the fixed rod 10 is symmetrically sleeved with a guide spring 11, and the two ends of the guide spring 11 are fixedly connected to the fixed block 7 and the mounting groove 9 respectively. The upper surfaces of the two semi-turbines 8 are fixedly connected with a sealing plug 12, and the upper surface of the sealing plug 12 is fixedly connected with a cleaning airbag 13. After the complete semi-turbine 8 is meshed with the worm 40, during the upward movement of the rubber hose 3, the semi-turbine 8 subjected to the meshing transmission can be gradually reset by the elastic force of the guide spring 11 in cooperation with the guide spring 11. At this time, the semi-turbine 8 can cooperate with the mounting groove 9 to move on the surface of the fixed block 7, which is beneficial to improving the resetting effect of the semi-turbine 8, and is convenient for the semi-turbine 8 to be reset by the elastic force of the guide spring 11 to clean the surface and interior of the rubber hose 3 for the second time, thereby improving the cleaning effect.

[0063] By setting the guide spring 11, the semi-turbine 8 can be reset by the elastic force of the guide spring 11 after the engagement with the worm 40 is cancelled, so that the semi-turbine 8 can be reset and cleaned again, and at the same time, it can better prepare for the subsequent cleaning and scraping work.

[0064] Further, such as Figure 9-10 As shown, one side of the air guide pipe 27 is connected to the top of the installation groove 9, and the other side of the air guide pipe 27 is connected to the bottom of the installation groove 9, and two outlets are provided at one end of the air guide pipe 27 away from the bellows 25. When the air guide pipe 27 transmits air through the squeezing of the positioning plate 24, the positions of the two air guide pipes 27 are one up and the other down, so that when the air guide pipe 27 transmits air to the groove 19, it can push the piston blocks 22 at two different positions, so that the two piston blocks 22 are always distributed in an up-and-down staggered manner.

[0065] The air guide pipes 27 are arranged to be staggered up and down so as to achieve the effect of applying pressure to the piston blocks 22 so that the two piston blocks 22 can be always in a state of being staggered up and down.

[0066] Further, such as Figure 8-Figure 10 As shown, the bottom end of the first return spring 23 on one side is fixedly connected to the piston block 22, and the top end of the first return spring 23 on the other side is connected to the piston block 22. The ends of the two first return springs 23 away from the piston block 22 are fixedly connected to the groove 19. During the reset process after the rubber hose 3 is squeezed out, the elastic force of the first return spring 23 can push the piston block 22 to move, so that the piston block 22 can be reset and moved in the groove 19, which is convenient for the next cup sealing operation.

[0067] By setting the first return spring 23, the piston block 22 can be reset and maintained in a fixed position by the elastic force of the first return spring 23. After the piston block 22 is pressurized, the first return spring 23 can cooperate and shrink, which is beneficial to improve the movement effect of the piston block 22 driving the second connecting plate 21 and the first return spring 23.

[0068] Further, such as Figure 3 As shown, the mounting frame 33 and the guide block 34 are symmetrically fixedly connected with telescopic tubes 35 on the facing surfaces, the surface of the telescopic tubes 35 is sleeved with a second return spring 36, and the surface of a single limit plate 38 is fixedly connected with a convex plate 39. After the double-layer cup is sealed, the bidirectional screw 37 can be driven to rotate by the motor output shaft. As the bidirectional screw 37 rotates, the two limit plates 38 are driven to move away from each other. At this time, the limit plates 38 can cancel the limit on the double-layer cup. At the same time, since the rubber hose 3 pushes the worm 40 during the downward movement, the telescopic tube can be used to 35. The cooperation of the second reset spring 36 enables the guide block 34 to move in the mounting frame 33 to avoid the situation where the worm 40 and the rubber feeding hose 3 are against each other. Moreover, when the rubber feeding hose 3 gradually moves upward and resets, the guide block 34 moves and resets in the mounting frame 33. At this time, the limit plate 38 is driven by the force so that the convex plate 39 can push and scrape the glue adhering part of the upward scraper plate 31 to avoid glue residue, which is beneficial to improve the effect of limiting the double-layer cup. At the same time, in the process of canceling the limit, the semi-turbine 8 can be driven to rotate to clean the rubber feeding hose 3 to improve the cleaning effect.

[0069] By setting the telescopic tube 35, the second return spring 36 and the convex plate 39, the position of the worm 40 can be adapted and moved during the downward movement of the rubber hose 3 to avoid interference. At the same time, the convex plate 39 can scrape and clean the glue adhered to the scraper plate 31 during the return movement of the guide block 34, which is beneficial to improving the overall use effect and processing continuity.
