[0002] Sponges are porous materials with good water absorption and can be used to clean items. Applying glue is an important step in the production of sponges, and it is mainly done using a glue coating machine.

[0003] The existing distance between the glue-applying roller and the conveyor belt is fixed and cannot be adjusted according to the thickness of the sponge. Moreover, the sponge does not have a positioning structure, so it is easy to shift during glue application, resulting in uneven glue application.

[0004] To address the above problems, this utility model provides an automatic sponge adhesive coating and uniform application device. Utility Model Content

[0005] The purpose of this invention is to provide an automatic glue coating device for sponges. By micro-clamping and positioning several sponges and moving them sequentially to contact the bottom of a glue roller to uniformly coat them with glue, the height can be adjusted to facilitate the glue roller to uniformly coat sponges of different thicknesses. The bottom of the glue box is attached to the outside of the glue roller to ensure that the glue roller can uniformly coat the sponges with glue, thereby solving the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic sponge adhesive coating device, comprising a U-shaped frame, a rectangular frame inside the U-shaped frame, a lead screw inside the lower end of the rectangular frame, a first motor at the end of the lead screw, a support plate at the upper end of the rectangular frame, a screw rod inside the rectangular frame, the screw rod rotating and moving vertically driving the support plate to rise and fall vertically, clamping plates symmetrically arranged on both sides of the upper end of the support plate, a bidirectional threaded lead screw threaded to the same side of the two clamping plates, a second motor at the end of the bidirectional threaded lead screw, an L-shaped plate fixed in the middle of the side of the U-shaped frame, an adhesive box at the upper end of the L-shaped plate, an adhesive roller attached to the bottom of the adhesive box, the adhesive roller rotating inside the L-shaped plate, and several evenly distributed round holes on the bottom surface of the adhesive box.

[0007] Furthermore, a through rectangular hole is provided in the middle of the bottom surface of the U-shaped frame. The outer side of the lower end of the rectangular frame is slidably connected to the inner side of the rectangular hole. The lead screw is threadedly connected to the inner side of the lower end of the rectangular frame. The first motor is fixedly installed on the outer wall of the U-shaped frame and its output end extends and is fixedly connected to the end of the lead screw. The outer side of the lead screw away from the first motor is rotatably connected to the inner side wall of the U-shaped frame through a bearing.

[0008] Furthermore, two symmetrical guide rods are fixed at the bottom of the support plate, and circular grooves are symmetrically opened on both sides of the upper surface of the rectangular frame. The guide rods are slidably connected to the inner surface of the corresponding circular grooves. The outer side of the screw is threadedly connected to the inner side of the middle part of the upper end of the rectangular frame. A handle is fixed at the bottom of the screw, and the outer side of the upper end of the screw is rotatably connected to the inner side of the middle part of the bottom end of the support plate through a bearing.

[0009] Furthermore, the bottom end of the clamping plate is slidably connected to the upper surface of the support plate, and the two clamping plates are slidably connected to the internal end of the same side away from the bidirectional threaded screw.

[0011] Furthermore, casters are fixedly installed at the four corners of the bottom of the U-shaped frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model provides an automatic sponge adhesive coating device. Several sponges are aligned and placed at the center of the upper part of a support plate. A second motor starts and drives a bidirectional threaded screw to rotate, causing the two clamping plates on both sides to move synchronously in opposite directions, slightly clamping and limiting the sponges on both sides. Then, adhesive is injected into the adhesive box. The adhesive roller is manually rotated, and the adhesive in the box is evenly coated onto the surface of the roller through a circular hole. Next, a first motor starts and drives the screw to rotate, causing a rectangular frame to move horizontally in a straight line. This causes the upper ends of several sponges to pass sequentially over the bottom of the adhesive roller. The adhesive roller rotates under friction, evenly coating the upper ends of the sponges with adhesive. The height of the support plate can be adjusted according to the thickness of the sponge. The screw is manually rotated, and the screw rotates and moves vertically up and down, which drives the support plate to move vertically up and down, thereby adjusting the distance between the bottom of the glue roller and the top of the sponge. This allows for the batch and uniform application of glue to sponges of different thicknesses. The purpose of this design is to uniformly apply glue by micro-clamping and positioning several sponges and moving them in sequence to contact the bottom of the glue roller. At the same time, the height adjustment facilitates the glue roller to uniformly apply glue to sponges of different thicknesses. The bottom of the glue box is attached to the outside of the glue roller to facilitate the glue roller to evenly apply glue to the sponge. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To solve the problem of how to effectively apply adhesive, such as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0021] An automatic sponge adhesive coating device includes a U-shaped frame 1, a rectangular frame 5 inside the U-shaped frame 1, a lead screw 3 inside the lower end of the rectangular frame 5, a first motor 4 at the end of the lead screw 3, a support plate 8 at the upper end of the rectangular frame 5, and a screw 6 inside the rectangular frame 5. The screw 6 rotates and moves vertically to drive the support plate 8 to rise and fall vertically. Clamping plates 15 are symmetrically arranged on both sides of the upper end of the support plate 8. A bidirectional threaded lead screw 12 is threadedly connected to the same side end of the two clamping plates 15. A second motor 14 is located at the end of the bidirectional threaded lead screw 12. An L-shaped plate 16 is fixed in the middle of the side of the U-shaped frame 1. A glue box 17 is arranged at the upper end of the L-shaped plate 16. A glue roller 19 is attached to the bottom end of the glue box 17 and rotates inside the L-shaped plate 16. Several evenly distributed round holes 18 are opened on the bottom surface of the glue box 17.

[0022] Specifically, several sponges are aligned and placed at the upper center of the support plate 8. Then, the second motor 14 starts and drives the bidirectional threaded screw 12 to rotate, causing the two clamping plates 15 to move synchronously towards each other, slightly clamping and limiting the sponges on both sides. Then, glue is injected into the glue box 17, and the glue roller 19 is manually rotated. The glue in the glue box 17 is evenly coated onto the surface of the glue roller 19 through the round hole 18. Next, the first motor 4 starts and drives the screw 3 to rotate, causing the rectangular frame 5 to move horizontally in a straight line. This causes the upper ends of several sponges to pass sequentially over the bottom end of the glue roller 19. The glue roller 19 rotates under friction, evenly coating the upper ends of the sponges with glue. The height of the support plate 8 is adjusted according to the thickness of the sponge. The screw 6 is manually rotated, and the screw 6 rotates and moves vertically up and down, which drives the support plate 8 to move vertically up and down, thereby adjusting the distance between the bottom end of the glue roller 19 and the top end of the sponge. This allows for the batch and uniform application of glue to sponges of different thicknesses. The purpose of this design is to uniformly apply glue by micro-clamping and positioning several sponges and moving them in sequence to contact the bottom end of the glue roller 19. At the same time, the height adjustment facilitates the glue roller 19 to uniformly apply glue to sponges of different thicknesses. The bottom end of the glue box 17 is attached to the outside of the glue roller 19, which facilitates the glue roller 19 to evenly apply glue, so as to uniformly apply glue to the sponge.

[0024] A through rectangular hole 2 is provided in the middle of the inner bottom surface of the U-shaped frame 1. The lower outer side of the rectangular frame 5 is slidably connected to the inner side of the rectangular hole 2. The lead screw 3 is threadedly connected to the lower inner side of the rectangular frame 5. The first motor 4 is fixedly installed on the outer wall of the U-shaped frame 1 and its output end extends and is fixedly connected to the end of the lead screw 3. The outer side of the lead screw 3 away from the first motor 4 is rotatably connected to the side wall of the U-shaped frame 1 through a bearing. The purpose of this design is that the first motor 4 drives the lead screw 3 to rotate, thereby driving the rectangular frame 5 to reciprocate linearly in the horizontal direction.

[0025] Furthermore, such as Figure 1-3 As shown, the following preferred technical solutions are provided:

[0026] Two symmetrical guide rods 9 are fixed at the bottom of the support plate 8. Circular grooves 10 are symmetrically opened on both sides of the upper surface of the rectangular frame 5. The guide rods 9 are slidably connected to the inner surface of the corresponding circular grooves 10. The outer side of the screw rod 6 is threadedly connected to the inner side of the middle part of the upper end of the rectangular frame 5. A handle 7 is fixed at the bottom of the screw rod 6. The outer side of the upper end of the screw rod 6 is rotatably connected to the inner side of the middle part of the bottom end of the support plate 8 through a bearing. The purpose of this design is to rotate and move the screw rod 6 vertically through the handle 7, thereby driving the support plate 8 to vertically lift and lower for height adjustment.

[0027] Furthermore, such as Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:

[0028] The bottom end of the clamping plate 15 is slidably connected to the upper end of the support plate 8. The two clamping plates 15 are slidably connected to the inner end of the same side away from the bidirectional threaded screw 12 by a connecting rod 13. Fixed plates 11 are symmetrically arranged at both ends of the bidirectional threaded screw 12 and the connecting rod 13. The bottom end of the fixed plate 11 is fixed to the upper end of the support plate 8, and the two ends of the connecting rod 13 are fixed to the side of the corresponding fixed plate 11. The outer ends of the two ends of the bidirectional threaded screw 12 are rotatably connected to the inner end of the corresponding fixed plate 11 through bearings. The second motor 14 is fixedly installed on the side of the corresponding fixed plate 11 and its output end is fixedly connected to the end of the bidirectional threaded screw 12. The purpose of this design is that the second motor 14 drives the bidirectional threaded screw 12 to rotate, thereby driving the clamping plates 15 on both sides to move synchronously towards or away from each other.

[0029] Furthermore, such as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0030] The glue box 17 is fixed to the inner side of the upper end of the L-shaped plate 16. The bottom end of the glue box 17 is processed into an arc shape and fits against the outer side of the glue roller 19. The outer side of the end of the glue roller 19 is rotatably connected to the side wall of the L-shaped plate 16 through a bearing. A handwheel 20 is fixed to the side of the end of the glue roller 19. The purpose of this design is to fit the bottom end of the glue box 17 against the outer side of the glue roller 19, so that the glue can be evenly coated on the outer surface of the glue roller 19 through the round hole 18.

[0031] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:

[0032] All four corners of the bottom of the U-shaped frame 1 are fixedly equipped with casters 21. The purpose of this design is to facilitate the movement and positioning of the U-shaped frame 1 by means of the casters 21.

[0033] In summary: Several sponges are aligned and placed at the upper center of the support plate 8. Then, the second motor 14 is started and drives the bidirectional threaded screw 12 to rotate, causing the clamping plates 15 on both sides to move synchronously in opposite directions, slightly clamping and limiting the sponges on both sides. Then, glue is injected into the glue box 17, and the glue roller 19 is manually rotated. The glue in the glue box 17 is evenly coated on the surface of the glue roller 19 through the round hole 18. Then, the first motor 4 is started and drives the screw 3 to rotate, causing the rectangular frame 5 to move horizontally in a straight line. This causes the upper ends of several sponges to pass sequentially over the bottom end of the glue roller 19. The glue roller 19 rotates under friction and evenly coats the upper ends of the sponges with glue. The height of the support plate 8 can be adjusted according to the thickness of the sponge. The screw 6 is manually rotated, and the screw 6 rotates and moves vertically up and down, which drives the support plate 8 to move vertically up and down, thereby adjusting the distance between the bottom end of the glue roller 19 and the top end of the sponge. This allows for the batch and uniform application of glue to sponges of different thicknesses. The purpose of this design is to uniformly apply glue by micro-clamping and positioning several sponges and moving them in sequence to contact the bottom end of the glue roller 19. At the same time, the height adjustment facilitates the glue roller 19 to uniformly apply glue to sponges of different thicknesses. The bottom end of the glue box 17 is attached to the outside of the glue roller 19, which facilitates the glue roller 19 to evenly apply glue, so as to uniformly apply glue to the sponge.
