Description

Technical Field

[0001] The present application relates to the technical field of gluing machines, and in particular to a gluing machine for uniform gluing. Background Art

[0002] Foam is a common cushioning material in everyday life. To facilitate installation, an adhesive layer can be added to the foam during production, allowing for direct installation of the foam product through the adhesive layer, improving efficiency. The adhesive layer is typically applied using a gluing machine, which applies glue to the foam surface. After the glue solidifies, a release film is attached to complete the process. The glue is specifically formulated for the adhesive layer and remains sticky even after solidification.

[0003] Utility model patent publication number CN220919729U discloses a gluing mechanism for foam sheets, comprising a frame, a gluing trough disposed along a conveyor path on the frame, and a gluing roller located within the trough and rotatably connected to the trough. Cover plates are hingedly connected to the front and back sides of the inner wall of the trough, and an arc-shaped baffle is provided near the cover plate near the gluing roller. The utility model provides a cover plate located directly above the gluing trough to shield the exposed notch of the trough, preventing glue from splashing out when the gluing roller rotates within the trough and also preventing dust from entering. The cover plate is also provided with a scraper to scrape excess glue off the gluing roller.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the scraper is long and can be deformed, and it is impossible to ensure that all positions of the scraper are in contact with the glue roller. In addition, there is a problem of excessive or insufficient pressing force at some positions, resulting in uneven amount of glue scraped off and uneven gluing. Utility Model Content

[0005] The present application provides a gluing machine for uniform gluing, which can adjust the pressing force of the scraper at different positions, so that the force of the scraper acting on the gluing roller is more uniform, and the gluing is more uniform.

[0006] The present application provides a gluing machine for uniform gluing, which adopts the following technical solution:

[0007] A gluing machine for uniform gluing includes a frame, a glue box, a gluing roller rotatably arranged on the frame, and an auxiliary roller. The frame is fixed with a support frame, the support frame is rotatably connected to a scraper, the upper end of the scraper is tilted and placed on the outer wall of the gluing roller, the support frame is provided with a plurality of screw seats, the screw seats are threadedly connected to screws, the screws are arranged along the length direction of the scraper, a spring is fixed to the end of the screw facing the scraper, the spring is rotatably connected to a rotating block toward the end of the scraper, and the rotating block abuts the surface of the scraper.

[0008] By adopting the above technical solution, the scraper is not a rigid body that will not deform. If it is found that the glue in certain positions of the foam is uneven, it means that the pressure exerted by the scraper on the glue roller is inconsistent. By turning the screw and adjusting the length of the spring, the pressure exerted by the scraper on the glue roller can be adjusted to make the gluing uniform.

[0009] Optionally, a slide is provided on the top surface of the support frame, the length direction of the slide is parallel to the length direction of the scraper, and the screw seat is slidably connected to the slide through the bottom end.

[0010] By adopting the above technical solution, the position of the screw seat can be adjusted, and by sliding the screw seat to the position where the glue is unevenly scraped, it is more targeted and easy to adjust.

[0011] Optionally, a slide groove is provided on the inner side of the top of the glue box, the slide groove is slidably connected to a box cover, and an avoidance opening is provided on a side of the box cover close to the upper glue roller.

[0012] By adopting the above technical solution, the avoidance opening is used to avoid the glue roller, so that the glue roller does not contact the box cover when rotating. The box cover covers the top of the glue box to prevent dust from falling into the glue box. After the box cover is removed by sliding it, it is easy to observe and clean the inside of the glue box.

[0013] Optionally, the scraper is rotatably connected to the support frame through the middle portion, and the lower end of the scraper extends into the avoidance opening.

[0014] By adopting the above technical solution, after the scraper scrapes off the excess glue on the upper glue roller, the glue will fall back into the glue box from the avoidance opening along the inclined surface of the scraper.

[0015] Optionally, the glue box is slidably connected to a liquid level rod in a vertical direction, the liquid level rod is provided with a scale, an L-shaped rod is fixed to the lower end of the liquid level rod, and a floating block is fixed to the lower end of the L-shaped rod, and the floating block floats on the glue in the glue box.

[0016] By adopting the above technical solution, since the float always floats on the surface of the glue, when the glue level in the glue box changes, the height of the liquid level rod relative to the top surface of the glue box also changes. The staff can determine whether glue needs to be added by observing the scale.

[0017] Optionally, the distance between the floating block and the inner wall of the rubber box is greater than 5 cm.

[0018] By adopting the above technical solution, the glue has a greater viscosity and lower fluidity. The glue close to the inner wall of the glue box is prone to having a higher liquid level due to the wall hanging effect. The distance between the float block and the inner wall of the glue box is greater than 5 cm, which is used to avoid inaccurate liquid level measurement. The measurement position of the float block is made as close to the middle of the glue box as possible to improve the accuracy of the liquid level measurement.

[0019] Optionally, a funnel is installed on the box cover, and a glue injection hole is provided through the box cover, and the glue injection hole is a threaded hole. The funnel is threadedly connected to the glue injection hole through the outer wall of the lower end.

[0020] By adopting the above technical solution, it is convenient to inject glue into the glue box through the funnel, and the threaded connection method is used to facilitate the disassembly and assembly of the funnel.

[0021] Optionally, a cover plate is hinged to the top of the funnel, and the cover plate covers the top of the funnel.

[0022] By adopting the above technical solution, the cover plate covers the top of the funnel to prevent dust from falling into the funnel and contaminating the glue. When glue injection is required, the cover plate is rotated to expose the top of the funnel.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Adjust the length of the spring by turning the screw, thereby adjusting the pressure of the scraper on the glue roller, so that the scraper can scrape off a uniform amount of glue, thus ensuring uniform glue application;

[0025] 2. The position of the screw seat can be adjusted. By sliding the screw seat to the position where the glue is unevenly scraped, the adjustment is more targeted and helps to complete the adjustment quickly;

[0026] 3. By setting the liquid level rod, it is easy to understand the glue level in the glue box. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present application is further described in detail below with reference to the accompanying drawings.

[0033] Reference Figure 1 This embodiment discloses a gluing machine for uniform gluing, including a frame 1, a glue box 2, a gluing roller 11 rotatably arranged on the frame 1, and an auxiliary roller 12. The glue box 2 is a box with an open top. Glue is stored in the glue box 2. The lower part of the gluing roller 11 is immersed in the glue box 2. When the gluing roller 11 rotates, the outer wall will bring out the glue in the glue box 2. The auxiliary roller 12 is used to cooperate with the gluing roller 11 to clamp the foam to be glued. A motor 13 is fixed on the frame 1. The output end of the motor 13 is transmission-connected to the gluing roller 11. The motor 13 is used to drive the gluing roller 11 to rotate.

[0034] Reference Figure 1 and Figure 2 The top inner side of the glue box 2 is provided with a chute 21, to which the box cover 3 is slidably connected. The box cover 3 has an escape hole 31 on the side near the glue roller 11. The escape hole 31 is used to avoid the glue roller 11 so that the glue roller 11 does not come into contact with the box cover 3 when rotating. After the box cover 3 is removed by sliding it, it is convenient to observe and clean the interior of the glue box 2.

[0035] Reference Figure 2 and Figure 3 The frame 1 is fixed with a support frame 4, which is rotatably connected to a scraper 5. The length of the scraper 5 is adapted to the upper glue roller 11. The scraper 5 is rotatably connected to the support frame 4 through the middle portion. The lower end of the scraper 5 extends into the avoidance opening 31, and the upper end of the scraper 5 is tilted and rests on the outer wall of the upper glue roller 11. After the scraper 5 scrapes off the excess glue on the outer surface of the upper glue roller 11, the glue will fall back into the glue box 2 through the avoidance opening 31 along the inclined surface of the scraper 5.

[0036] The top surface of the support frame 4 is provided with a slideway 41, the length direction of the slideway 41 being parallel to the length direction of the scraper 5. The slideway 41 is a dovetail groove, and the two ends of the slideway 41 pass through the two ends of the support frame 4. The support frame 4 is provided with a plurality of screw seats 42, which are slidably connected to the slideway 41 through the bottom end. By sliding the screw seat 42, the position of the screw seat 42 relative to the scraper 5 can be adjusted, and the screw seat 42 can also be removed or a new screw seat 42 can be added through the end of the slideway 41. The screw seat 42 is threadedly connected to a screw rod 43, which is arranged along the length direction of the scraper 5. A spring 44 is fixed to the end of the screw rod 43 facing the scraper 5. The spring 44 is rotatably connected to a rotating block 45 toward the end of the scraper 5, and the rotating block 45 abuts the surface of the scraper 5.

[0037] A handle is fixed to the end of the screw 43 away from the scraper 5. When the screw 43 is rotated, it moves axially through the threaded connection with the screw seat 42, thereby compressing or stretching the spring 44, thereby adjusting the pressure applied to the corresponding position of the scraper 5. By providing a rotating block 45, the spring 44 does not rotate when the screw 43 rotates, preventing spontaneous movement between the rotating block 45 and the scraper 5. The rotating block 45 always contacts the scraper 5 in surface contact, and the spring 44 adaptively bends and deforms as it expands and contracts. When the screw seat 42 slides on the slide 41, the spring 44 drives the rotating block 45 along with it, and the rotating block 45 slides across the surface of the scraper 5. The reaction force of the spring 44 acts on the screw seat 42, pressing the screw seat 42 against the inner wall of the slide 41 and the top surface of the support frame 4, thereby increasing the friction of the screw seat 42. During normal operation of the equipment, the screw seat 42 will not move spontaneously, and there is no need to provide a structure to lock the screw seat 42 in place.

[0038] Reference Figure 1 and Figure 4 A liquid level rod 6 is vertically slidably connected to the glue box 2. The rod 6 is provided with a scale 61. An L-shaped rod 62 is fixed to the lower end of the rod 6. A float 63 is fixed to the lower end of the L-shaped rod 62. The float 63 floats on the glue inside the glue box 2. The distance between the float 63 and the inner wall of the glue box 2 is greater than 5 cm. This distance is achieved by the horizontal section of the L-shaped rod 62. The inner wall of the glue box 2 is provided with a guide groove for the vertical sliding of the L-shaped rod 62. Because the float 63 always floats on the surface of the glue, changes in the glue level inside the glue box 2 also change the height of the rod 6 relative to the top surface of the glue box 2. By observing the scale 61, a person can determine whether glue needs to be added. The glue has a high viscosity and low fluidity. The glue near the inner wall of the glue box 2 is likely to have a higher liquid level due to the wall hanging effect. The distance between the float 63 and the inner wall of the glue box 2 is greater than 5 cm. This is used to avoid inaccurate liquid level measurement. The measurement position of the float 63 is made as close to the middle of the glue box 2 as possible to improve the accuracy of the liquid level measurement.

[0039] A funnel 7 is mounted on the lid 3. A glue injection hole 32 is threaded through the lid 3. The funnel 7 is threadedly connected to the glue injection hole 32 via the outer wall of its lower end. This threaded connection facilitates assembly and disassembly of the funnel 7. A cover plate 71 is hingedly connected to the top of the funnel 7. This covers the top of the funnel 7 to prevent dust from falling into the funnel 7 and contaminating the glue. When glue injection is required, the cover plate 71 is rotated to expose the top of the funnel 7.

[0040] The gluing machine for uniform gluing according to the embodiment of the present application operates as follows: a gluing roller 11 and an auxiliary roller 12 clamp the foam to be glued, and a motor 13 drives the gluing roller 11 to rotate clockwise, thereby moving the foam. As the gluing roller 11 rotates, its lower portion is immersed in the glue in the glue tank 2, so the outer wall of the gluing roller 11 carries glue. The scraper 5 scrapes off the excess glue from the outside of the gluing roller 11, and the uniform glue on the outside of the gluing roller 11 then contacts the foam, completing the gluing of the foam.

[0041] The scraper 5 is not a rigid body that will not deform. If it is found that the glue in certain positions of the foam is uneven, it means that the pressure exerted by the scraper 5 on the glue roller 11 is inconsistent. In this case, by sliding the screw seat 42 to the uneven position, rotating the screw 43, and adjusting the length of the spring 44, the pressure exerted by the scraper 5 on the glue roller 11 is adjusted to make the glue application uniform.

[0042] In addition, the glue level in the glue box 2 is observed through the liquid level rod 6. If the glue in the glue box 2 is too little, new glue is injected into the glue box 2 through the funnel 7.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
