Description

Technical Field

[0001] This invention relates to the field of vacuum forming equipment technology, and in particular to a production equipment and process for a circular arc-shaped vacuum forming sealing strip. Background Technology

[0002] Edge trim, also known as finishing strip, is a material used for decoration and finishing. In decoration, edge trim is usually used at the junction of different materials, such as between floor and wall, ceiling and wall, etc., to play a role in aesthetics and transition. In order to increase the versatility of edge trim, adapt to different decoration styles, and improve the durability of edge trim, edge trim needs to be processed by vacuum forming equipment. Vacuum forming equipment is a special machine used to produce vacuum-formed products. Vacuum forming equipment mainly includes vacuum forming machine and edge trimming machine.

[0003] Patent publication number CN220499923U discloses a PVC vacuum forming device, including a base. The top of the base has a movable groove, and a cylinder is fixedly installed on the inner wall of the movable groove. A pneumatic rod is fixedly installed at the output end of the cylinder, and a connecting plate is fixedly installed on the top of the pneumatic rod. A mold is fixedly installed on the top of the connecting plate. A fixing mechanism is provided on the top of the base, including a fixing ring block. The fixing ring block is fixedly installed on the top of the base, and a placement groove is opened on the top of the fixing ring block. A connecting block is fixedly installed on the top of the fixing ring block. This PVC vacuum forming device, by setting a fixing mechanism, can achieve the purpose of fixing PVC film. The PVC film is fixed by the mutual compression of the fixing ring block and the pressing ring block, avoiding manual stretching of the PVC film, reducing the harm to the human body from the gases generated by PVC after heating, and reducing manual labor time.

[0004] The existing technology has the following drawbacks:

[0005] When the equipment is in use, the vacuum forming machine uses negative pressure to adsorb the film onto the surface of the sealing strip. Then, the edge trimming machine cuts the film along the outer contour of the sealing strip. However, because the surface of the sealing strip is not flat, when the film is directly adsorbed onto the surface of the sealing strip by negative pressure during the lamination process, the film shrinks rapidly and synchronously, which can easily cause wrinkles in the film and make it impossible to fully adhere to the sealing strip. This requires peeling and rework, affecting product quality and efficiency. Summary of the Invention

[0006] In view of the problem of wrinkles appearing after lamination in existing technologies, a production equipment and process for arc-shaped vacuum forming sealing strips is proposed.

[0007] This application provides a production equipment and process for producing arc-shaped vacuum forming strips, the purpose of which is to avoid wrinkles after covering.

[0008] The technical solution of the present invention is as follows: A production device for arc-shaped plastic suction closing strips, used for surface film covering of closing strips, includes a device main body, a placement table arranged on the side of the device main body, a sliding table arranged inside the placement table, a placement board and a sealing and pressing frame arranged on the top of the sliding table, plastic suction air holes opened on the surface of the placement board, a suction device arranged inside the sliding table, and further includes a mold and positioning bolts arranged on the upper surface of the placement board, positioning bolt grooves opened at the bottom of the mold. The suction device specifically includes a support component, a suction component and a power control component arranged inside the sliding table;

[0009] The plastic suction air holes are distributed in a rectangular array. The mold includes two types, A and B. The upper surfaces of the two types of molds are designed according to the inner two sides of the closing strip respectively, so that the mold can fit with the closing strip. One end of the positioning bolt is inserted into the plastic suction air hole, and the other end is inserted into the positioning bolt groove. The number of positioning bolts is not less than two.

[0010] Further, the support component includes a bottom board arranged on the inner bottom wall of the sliding table, a storage groove and a slot arranged on the top of the bottom board.

[0011] Further, the arranged suction component includes a branch pipe arranged on the top of the bottom board, a control pipe arranged outside the branch pipe, a connecting air pipe and a support leg arranged at the bottom of the branch pipe, and a connecting hole arranged on the top of the branch pipe;

[0012] The branch pipe is annular, and there are two or more branch pipes. The branch pipes are sleeved with each other in a ring shape, showing a "return" shape. The branch pipes are arranged along the distribution path of the plastic suction air holes. The control pipe penetrates the branch pipe in the horizontal direction. The connecting air pipe extends out multiple branches, and the branches are respectively connected to each branch pipe. One of the branches of the connecting air pipe extends downward through the sliding table. The connecting air pipe is located in the storage groove. The connecting holes correspond to the plastic suction air holes one by one, and the support legs are inserted into the slots.

[0013] Further, the power control component includes a plugging rod arranged inside the control pipe, a connecting rod arranged at one end of the plugging rod facing the opening of the control pipe, a tooth groove arranged on the surface of the connecting rod, a protective cover arranged on the top of the bottom board, a driving motor arranged inside the protective cover, a gear arranged at the bottom of the driving motor, and an extension groove arranged outside the protective cover;

[0014] The plugging rod plugs the connection between the connecting air pipe and the branch pipe. The connecting rod extends out of the control pipe and penetrates the extension groove. The connecting rod is meshed with the gear through the tooth groove.

[0015] Further, a connecting component is arranged between the connecting hole and the plastic suction air hole.

[0016] Further, an installation groove is opened on the top of the bottom board, and a telescopic rod is arranged inside the installation groove;

[0017] The top of the mounting groove fits against the bottom of the placement plate, and the sealing frame surrounds the outside of the placement plate.

[0018] Furthermore, the connecting assembly includes a rotating sleeve disposed within the vacuum forming air hole and the connecting hole, an inner core disposed inside the rotating sleeve, and an elastic hose disposed between the two inner cores.

[0019] The rotating sleeve is threadedly connected to the vacuum forming air hole and the connecting hole respectively, the inner core and the rotating sleeve are rotatably connected, and the elastic hose is spirally coiled.

[0020] Furthermore, the connecting assembly also includes a hollow groove at the end of the inner core away from the elastic hose disposed within the blister air hole, a sealing core and a spring disposed within the hollow groove, and a ventilation groove disposed within the inner core disposed within the blister air hole.

[0021] The flexible hose is connected to the hollow groove. One end of the venting groove extends to the side of the inner core near the flexible hose, and the other end extends to the inner wall of the hollow groove. The sealing core seals the opening of the venting groove.

[0022] A process for producing arc-shaped vacuum forming edge strips, using arc-shaped vacuum forming edge strip production equipment, includes the following steps:

[0023] Step 1: Cutting, Grooving, and Assembling. Use cutting equipment to cut the raw materials to the required size to obtain the preliminary shape of the edge strip; cut tongue and groove grooves at specific positions on the edge strip for subsequent splicing and fixing; glue and fix the edge strip components with tongue and groove grooves; use appropriate glue to ensure a firm bond and avoid loosening during subsequent processing.

[0024] Step 2: Trim and mill the edges. Use an edge planer or sander to trim the edges of the bonded and fixed edge strip to make them neat and smooth. Use a milling machine to mill the edge strip to give it a specific shape and contour.

[0025] Step 3: First sanding, second fine sanding, and glue application. Use sandpaper or a sander to sand the milled edge strip for the first time to remove burrs, rough parts, and machining marks. Apply putty to the surface of the edge strip to fill small imperfections and depressions. After the putty dries, perform a second fine sanding to make the surface smoother and more delicate. Spray glue evenly onto the surface of the edge strip to prepare for the subsequent lamination operation.

[0026] Step 4: Place mold A and place the sealing strip and cover it with film. Place mold A in a suitable position above the placement plate, and then place the sealing strip after spraying glue on the mold, ensuring that the sealing strip is tightly attached to the mold; start the main body of the equipment, cover the edge of the sealing strip with plastic film, and use heating and vacuum adsorption to make the film tightly adhere to the surface of the sealing strip.

[0027] Step 5: Trimming, fine sanding, and applying adhesive. Use a knife or trimming machine to trim the edges of the laminated edge strip to make them neat and aesthetically pleasing. Use fine sandpaper or a sander to sand the trimmed edge strip again to further improve the smoothness and quality of the surface. Be careful to avoid over-sanding, which could damage the film. Apply adhesive again to the surface of the edge strip to prepare for lamination of the curved surface.

[0028] Step 6: Place mold B and place the sealing strip and apply film. Place mold B in a suitable position above the placement plate, and then place the sealed strip after spraying glue on the mold, ensuring that the sealed strip is tightly attached to the mold; follow a similar operation as the edge film application to apply film to the arc surface of the sealed strip.

[0029] Step 7: Trimming. Perform final trimming on the edge of the curved surface after film coating to remove excess film edges and make the overall appearance of the edge of the edge more perfect.

[0030] Furthermore, the operating parameters of the main body of the equipment are: temperature 120℃-130℃, duration 3 minutes, positive pressure set to 0.3Mpa-0.4Mpa, and negative pressure set to 0.07Mpa-0.08Mpa.

[0031] The beneficial effects of this invention are:

[0032] 1. By setting up a mold, during processing, the sealing strip adheres to the outside of the mold, which plays a role in fixing and supporting the sealing strip. During film lamination, it prevents the sealing strip from being squeezed and deviating, and also avoids the sealing strip from being deformed due to the pressure of the film. At the same time, the mold also raises the sealing strip so that the film can wrap the sealing strip to the maximum extent, ensuring processing quality and efficiency. The positioning pins can play a positioning role in the mold, preventing the mold from shifting.

[0033] 2. By setting up support components, suction components, and power control components, during operation, the sealing rod moves, causing the outermost branch pipe to connect with the connecting air pipe first. The suction force generated by the corresponding vacuum forming air hole of the branch pipe adsorbs the edge of the film onto the surface of the placement plate, and the film also begins to shrink towards the sealing strip. Subsequently, the suction force continuously moves the vacuum forming air hole closer to the sealing strip, and the film continues to shrink until it completely wraps the sealing strip. In this way, the film is gradually tightened from the outside to the inside, which can prevent the film from wrinkling and ensure product quality.

[0034] 3. By using connecting components to connect the branch pipes and the vacuum forming air holes, the flexible hose can be stretched and deformed at will, so that the connecting holes and vacuum forming air holes can be matched at will according to the actual situation. Thus, when the number and specifications of the mold change, by adjusting the position of the vacuum forming air holes connected to the branch pipes, the vacuum forming air holes corresponding to the branch pipes are always distributed around the mold, ensuring that the film can shrink normally.

[0035] 4. By setting up the connecting components, during the vacuum forming process, the sealing core moves towards the flexible hose to open the venting groove, completing the vacuum forming work. After the vacuum forming is completed, the hollow groove rebounds and pushes the sealing core upward. The sealing core pushes out the film embedded in the hollow groove, which facilitates the subsequent waste film cleaning work. Attached Figure Description

[0054] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0055] Example 1, referring to Figure 1-16 This is the first embodiment of the present invention, which provides a production equipment for producing arc-shaped vacuum forming strips for surface coating of the strips. The equipment includes a main body 1, a placement platform 2 disposed on the side of the main body 1, a sliding platform 3 disposed in the placement platform 2, a placement plate 4 and a sealing frame 5 disposed on the top of the sliding platform 3, vacuum forming air holes 41 opened on the surface of the placement plate 4, a suction device 8 disposed inside the sliding platform 3, and a mold 6 and a positioning pin 7 disposed on the upper surface of the placement plate 4, and a positioning pin groove 61 opened at the bottom of the mold 6. The suction device 8 specifically includes a support component 81, a suction component 82 and a power control component 83 disposed in the sliding platform 3.

[0056] Specifically, the main body 1 is equipped with a pressurizing device and a sealing device. The sealing device is pressed against the top of the placement plate 4. The placement platform 2 is welded to the outside of the main body 1. The sliding platform 3 is slidably installed in the placement platform 2. The placement plate 4 is placed on top of the sliding platform 3. The sealing frame 5 is rotatably connected to the top of the sliding platform 3. The vacuum forming air holes 41 are distributed in a rectangular array. The mold 6 includes two types, A and B. The upper surfaces of the two molds 6 are designed according to the inner two sides of the closing strip, so that the mold 6 can fit with the closing strip. One end of the positioning bolt 7 is inserted into the vacuum forming air hole 41, and the other end is inserted into the positioning bolt groove 61. The number of positioning bolts 7 is not less than two.

[0057] By setting the mold 6, during processing, the closing strip is attached to the outer side of the mold 6, which plays a role in fixing and supporting the closing strip. During film covering, it prevents the closing strip from being squeezed and running off, and can also avoid the deformation of the closing strip due to the pressure of the film. At the same time, the mold 6 also raises the closing strip, enabling the film skin to wrap the closing strip to the maximum extent, ensuring the processing quality and efficiency. The positioning bolt 7 can play a role in positioning the mold 6 to prevent the mold 6 from shifting.

[0058] The support component 81 includes a bottom plate 811 provided on the inner bottom wall of the sliding table 3, a storage groove 812 and a slot 813 provided on the top of the bottom plate 811; the suction component 82 includes a branch pipe 821 provided on the top of the bottom plate 811, a control pipe 822 provided on the outer side of the branch pipe 821, a connecting air pipe 823 and a support leg 825 provided on the bottom of the branch pipe 821, and a connecting hole 824 provided on the top of the branch pipe 821; the power control component 83 includes a plugging rod 831 provided inside the control pipe 822, a connecting rod 832 provided at one end of the plugging rod 831 facing the opening of the control pipe 822, a tooth groove 833 provided on the surface of the connecting rod 832, a protective cover 834 provided on the top of the bottom plate 811, a driving motor 835 provided inside the protective cover 834, a gear 836 provided at the bottom of the driving motor 835, and an extension groove 837 provided on the outer side of the protective cover 834.

[0059] Specifically, the bottom plate 811 is placed inside the sliding table 3. The branch pipe 821 is annular, and two or more branch pipes 821 are provided. The branch pipes 821 are nested with each other in a "hui" - shaped pattern. The branch pipe 821 is arranged along the distribution path of the vacuum forming air holes 41. The control pipe 822 penetrates the branch pipe 821 horizontally and is welded to it. The connecting air pipe 823 extends out multiple branches, and the branches are respectively connected to each branch pipe 821. One branch of the connecting air pipe 823 extends downward through the sliding table 3. The connecting air pipe 823 is located in the storage groove 812. The connecting holes 824 correspond to the vacuum forming air holes 41 one by one. The support legs 825 are inserted into the slots 813. A vacuuming device is provided at the bottom of the sliding table 3.

[0060] The plugging rod 831 is slidably installed inside the control pipe 822. The plugging rod 831 plugs the connection between the connecting air pipe 823 and the branch pipe 821. The connecting rod 832 is thread - connected to the plugging rod 831. The connecting rod 832 extends out of the control pipe 822 and penetrates the extension groove 837. The connecting rod 832 is meshed with the gear 836 through the tooth groove 833. The protective cover 834 and the bottom plate 811 are fixed by bolts. The driving motor 835 and the protective cover 834 are fixed by bolts.

[0061] By setting up a support component 81, a suction component 82, and a power control component 83, during operation, the sealing rod 831 moves, causing the outermost branch pipe 821 to connect with the connecting air pipe 823 first. The suction force generated by the suction hole 41 corresponding to the branch pipe 821 adsorbs the edge of the film onto the surface of the placement plate 4, and the film also begins to shrink towards the closing strip. Subsequently, the suction force generated by the suction hole 41 continuously moves closer to the closing strip, and the film continues to shrink until it completely wraps the closing strip. In this way, the film is gradually tightened from the outside to the inside, which can prevent the film from wrinkling and ensure product quality.

[0062] By using the connecting component 9 to connect the branch pipe 821 and the vacuum forming air hole 41, the elastic hose 93 can be stretched and deformed at will, so that the connecting hole 824 and the vacuum forming air hole 41 can be matched at will according to the actual situation. Thus, when the number and specifications of the mold 6 change, by adjusting the position of the vacuum forming air hole 41 connected to the branch pipe 821, the vacuum forming air hole 41 corresponding to the branch pipe 821 is always distributed around the mold 6, ensuring that the film can shrink normally.

[0063] The top of the base plate 811 is provided with a mounting groove 42, and a telescopic rod 43 is provided inside the mounting groove 42;

[0064] Specifically, the top of the mounting groove 42 is attached to the bottom of the placement plate 4 and fixed by bolts, the telescopic rod 43 is threaded into the mounting groove 42, and the sealing frame 5 surrounds the outside of the placement plate 4.

[0065] By setting the mounting slot 42, the mounting slot 42 can lift the placement plate 4 upward and separate it from the sliding table 3, so that the connecting component 9 is fully exposed. This makes it convenient to install and disassemble the connecting component 9 and to adjust the connection method of the connecting component 9.

[0066] A connecting component 9 is provided between the connecting hole 824 and the vacuum forming air hole 41. The connecting component 9 includes a rotating sleeve 91 disposed in the vacuum forming air hole 41 and the connecting hole 824, an inner core 92 disposed inside the rotating sleeve 91, and an elastic hose 93 disposed between the two inner cores 92. The connecting component 9 also includes a hollow groove 94 disposed in the vacuum forming air hole 41 at the end of the inner core 92 away from the elastic hose 93, a sealing core 95 and a spring 96 disposed inside the hollow groove 94, and a ventilation groove 97 disposed inside the inner core 92 in the vacuum forming air hole 41.

[0067] Specifically, the rotating sleeve 91 is threadedly connected to the vacuum forming air hole 41 and the connecting hole 824 respectively. The inner core 92 and the rotating sleeve 91 are rotatably connected. The elastic hose 93 is spirally coiled. The elastic hose 93 is connected to the hollow groove 94 and the ventilation groove 97. The sealing core 95 is slidably connected in the hollow groove 94. One end of the ventilation groove 97 extends to the side of the inner core 92 near the elastic hose 93, and the other end extends to the inner wall of the hollow groove 94. The sealing core 95 seals the opening of the ventilation groove 97.

[0068] By setting the connecting component 9, during the vacuum forming process, the sealing core 95 moves towards the elastic hose 93 to open the venting groove 97, thus completing the vacuum forming work. After the vacuum forming is completed, the hollow groove 94 rebounds and pushes the sealing core 95 upward. The sealing core 95 pushes out the film embedded in the hollow groove 94, which facilitates the subsequent waste film cleaning work.

[0069] Example 2, refer to Figure 1-16 The second embodiment of the present invention provides: a production process for a circular arc-shaped vacuum forming edge strip, using circular arc-shaped vacuum forming edge strip production equipment, including the following steps:

[0070] Step 1: Cutting, Grooving, and Assembling. Use cutting equipment to cut the raw materials to the required size to obtain the preliminary shape of the edge strip; cut tongue and groove grooves at specific positions on the edge strip for subsequent splicing and fixing; glue and fix the edge strip components with tongue and groove grooves; use appropriate glue to ensure a firm bond and avoid loosening during subsequent processing.

[0071] Step 2: Trim and mill the edges. Use an edge planer or sander to trim the edges of the bonded and fixed edge strip to make them neat and smooth. Use a milling machine to mill the edge strip to give it a specific shape and contour.

[0072] Step 3: First sanding, second fine sanding, and glue application. Use sandpaper or a sander to sand the milled edge strip for the first time to remove burrs, rough parts, and machining marks. Apply putty to the surface of the edge strip to fill small imperfections and depressions. After the putty dries, perform a second fine sanding to make the surface smoother and more delicate. Spray glue evenly onto the surface of the edge strip to prepare for the subsequent lamination operation.

[0073] Step 4: Place mold A 6 and place the sealing strip and cover it with film. Place mold A 6 in a suitable position above the placement plate 4, and then place the sealing strip after spraying glue on mold 6, ensuring that the sealing strip is tightly attached to mold 6; start the main body of the equipment 1, cover the edge of the sealing strip with plastic film, and use heating and vacuum adsorption to make the film tightly attached to the surface of the sealing strip.

[0074] Step 5: Trimming, fine sanding, and applying adhesive. Use a knife or trimming machine to trim the edges of the laminated edge strip to make them neat and aesthetically pleasing. Use fine sandpaper or a sander to sand the trimmed edge strip again to further improve the smoothness and quality of the surface. Be careful to avoid over-sanding, which could damage the film. Apply adhesive again to the surface of the edge strip to prepare for lamination of the curved surface.

[0075] Step 6: Place mold B 6 and place the sealing strip and apply film. Place mold B 6 in a suitable position above the placement plate 4, and then place the sealing strip after spraying glue on mold 6, ensuring that the sealing strip is tightly attached to mold 6; follow a similar operation to the edge film application to apply film to the arc surface of the sealing strip.

[0076] Step 7: Trimming. Perform final trimming on the edge of the curved surface after film coating to remove excess film edges and make the overall appearance of the edge of the edge more perfect.

[0077] Example 3 is the third embodiment of the present invention. This embodiment differs from the second embodiment in that the operating parameters of the main body 1 of the device are: temperature 120°C, duration 3 minutes, positive pressure set to 0.3 MPa, and negative pressure set to 0.07 MPa.

[0078] Example 4 is the fourth embodiment of the present invention. This embodiment differs from the second embodiment in that the operating parameters of the main body 1 of the device are: temperature 130°C, duration 3 minutes, positive pressure set to 0.4 MPa, and negative pressure set to 0.08 MPa.

[0079] In conjunction with Embodiment 1, the working principle of the arc-shaped vacuum forming edge strip production equipment of the present invention is as follows:

[0080] During installation, place the base plate 811 into the sliding table 3, then place the branch pipe 821 above the base plate 811, insert the support leg 825 into the slot 813, then connect the connecting rod 832 to the sealing rod 831, and then insert the connecting rod 832 into the control pipe 822; install the drive motor 835 into the protective cover 834, and then place the protective cover 834 above the base plate 811 from the center of the branch pipe 821. During this process, continuously adjust until the connecting rod 832 is engaged in the outer groove 837, and the gear 836 meshes with the tooth groove 833. This completes the assembly of the suction device 8.

[0081] Next, insert the telescopic rods 43 one by one into the mounting slots 42, fix the placement plate 4 above the telescopic rods 43, insert the positioning pins 7 into the corresponding positions according to the placement requirements of the mold 6, and then place the mold 6 above the placement plate 4, with the positioning pins 7 inserted into the positioning pin slots 61.

[0082] The telescopic rod 43 lifts the placement plate 4 upwards. According to the placement position of the mold 6, the connection method of the connecting component 9 is designed so that the innermost branch pipe 821 and the corresponding vacuum forming air hole 41 are all around the mold 6, which is set as the first ring. Then the vacuum forming air hole 41 connected to the outer branch pipe 821 is located around the first ring of the mold 6, which is set as the second ring, and so on. The installation method of the connecting component 9 is to insert the rotating sleeve 91 with the sealing core 95 into the vacuum forming air hole 41, and then insert the other end of the rotating sleeve 91 into the connecting hole 824.

[0083] When in use, first place the sealing strip on top of the mold 6. After it is placed stably, move to the lifting and sealing frame 5. Lay a thin film on top of the sliding table 3, then put down the sealing frame 5 and press it against the edge of the film. Then send the sliding table 3 into the main body 1 of the equipment.

[0084] The main body of the equipment 1 heats the film and then starts the vacuuming equipment. The vacuuming equipment generates negative pressure in the connecting air pipe 823. This force is then transmitted to the elastic hose 93 through the connecting hole 824 and the inner core 92 connected to it. Then, the sealing core 95 moves downward under the influence of negative pressure and compresses the spring 96. After the sealing core 95 moves a certain distance, the ventilation groove 97 is opened, so that the suction force generated by the negative pressure is transmitted to the top of the blister air hole 41, which generates an adsorption force on the film above the placement plate 4. At the same time, the drive motor 835 starts, the gear 836 rotates, and drives the connecting rod 832 to gradually pull the sealing rod 831 out of the control pipe 822, so that more and more branch pipes 821 connected to the connecting air pipe 823 are connected. The blister air hole 41 with adsorption force gradually moves from the outside of the mold 6 to the mold 6, and finally the outer adsorption work is completed.

[0085] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
