Description

Technical Field

[0001] This utility model relates to the technical field of water-based adhesive coating mechanism, and in particular to a water-based adhesive coating mechanism. Background Technology

[0002] Water-based adhesives, as the name suggests, are adhesives that use water as a solvent or dispersion medium. Compared to traditional oil-based adhesives, these are more environmentally friendly because they contain little or no organic solvents, thus reducing the emission of volatile organic compounds (VOCs), which helps protect the environment and improve the working environment. Water-based adhesives typically cure through water evaporation and cross-linking reactions of polymer chains. They are non-flammable and safe during operation. The application of water-based adhesives usually requires a coating machine.

[0003] For example, in the prior art, the patent with authorization announcement number CN222890041U discloses a coating mechanism of an environmentally friendly water-based adhesive laminating machine. The device, through the setting of a glue storage tank, a high-pressure pump and a glue spraying plate, allows the operator to connect the power supply of the high-pressure pump and the power supply of the drive motor when the operator is applying glue to the production fabric. The reciprocating screw drives the moving plate to slide back and forth along the surface of the sliding rod. The high-pressure pump then delivers the glue from the glue storage tank to the inside of the glue spraying plate, and the glue spraying plate then evenly delivers the glue to the surface of the production fabric.

[0004] The device can ensure uniform coating, but the lead screw of the device spans the fixed frame. The lead screw affects the placement of the production cloth to be coated into the fixed frame and also affects the removal of the coated production cloth from the fixed frame, affecting practicality. Therefore, a water-based adhesive coating mechanism is designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the above-mentioned background technology by proposing a water-based adhesive coating mechanism.

[0006] The technical problem to be solved by this utility model is to provide a water-based adhesive coating mechanism, which solves the problem in the prior art where the lead screw of the coating mechanism spans across the fixed frame, which affects the insertion of the production cloth into the coating frame and the removal of the production cloth after coating is completed.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a water-based adhesive coating mechanism, comprising a base, a mounting plate, a lead screw, a drive motor, pulleys, a transmission belt, and a coating assembly. Mounting plates are fixedly mounted on both the left and right surfaces of the base, and a lead screw is rotatably mounted between the two mounting plates. A drive motor is fixedly mounted on the inner end of the lead screw on the right side, and pulleys are fixedly mounted on the outer ends of the two lead screws. A transmission belt is sleeved between the two pulleys, and a coating assembly is spirally connected to the two lead screws.

[0008] The coating assembly includes an inverted concave frame, a glue storage tank, a coating tank, and a glue extraction pump. The two sides of the inverted concave frame are respectively threaded onto two lead screws. A glue storage tank is fixedly installed in the center of the upper surface of the inverted concave frame. A glue extraction pump is installed at the bottom of the glue storage tank. A coating tank that can ensure uniform coating of glue is fixedly installed at the output end of the glue extraction pump.

[0009] Preferably, the coating box includes a coating plate, a perforated plate, a blocking frame, vertical rods, and a through groove. The coating plate is fixedly installed at the bottom inner side of the coating box, the perforated plate is fixedly installed at the center inner side of the coating box, the blocking frame is slidably installed above the perforated plate, vertical rods are fixedly installed on both the left and right sides of the upper surface of the blocking frame, and through grooves are opened on both the left and right sides of the upper surface of the coating box.

[0010] Preferably, the blocking frame is in the form of a partition with multiple through slots.

[0011] Preferably, the vertical rod passes through the through groove.

[0012] Preferably, when the vertical rod slides to the innermost side of the through groove, the blocking frame is completely misaligned with the through hole on the perforated plate, and when the vertical rod slides to the outer end of the through groove, the blocking frame completely blocks the through hole on the perforated plate.

[0013] Preferably, the coating plate has a microporous plate structure, and the bottom horizontal height of the coating plate is lower than the bottom horizontal height of the coating box.

[0014] Preferably, springs are fixedly provided on both the left and right sides of the outer end of the blocking frame, and the outer ends of the springs are fixedly provided on the inner side of the coating box.

[0015] Preferably, when the spring is in its natural extended state, the blocking frame and the through hole on the perforated plate are completely misaligned, and at this time the vertical rod is at the innermost side of the through groove.

[0016] Preferably, the width of the inverted concave frame is equal to the width of the base, and the inner surface of the inverted concave frame is attached to the left and right sides of the base.

[0017] Preferably, a frosted rubber layer is adhered to the upper surface of the base.

[0018] Compared with the prior art, this utility model has at least the following beneficial effects:

[0019] 1. This utility model, by comprising a lead screw, pulleys, a transmission belt, and a coating assembly, allows for coating by placing the material to be coated on the base, adding water-based adhesive to the adhesive storage tank, turning on the adhesive pump to draw the water-based adhesive into the coating tank, and then turning on the drive motor to rotate the outer lead screw. The pulley on the outer lead screw drives the inner pulley to rotate via the transmission belt, causing both lead screws to rotate in the same direction. The two lead screws drive the inverted concave frame to move left and right, allowing the coating tank to coat the material. The lead screws do not interfere with the material being placed on the base, ensuring convenient coating. Furthermore, the single drive motor drives the two lead screws to rotate synchronously, resulting in better coordination and greater energy efficiency.

[0020] 2. This utility model features a coating box. When coating is performed through the coating box, first, grasp the vertical rod and pull it to the left. The vertical rod moves the blocking frame outward, completely blocking the through holes on the perforated plate. Then, turn on the glue pump, which draws the water-based glue from the storage tank into the coating box. At this point, the water-based glue will not pass through the through holes on the perforated plate. When the perforated plate is fully coated with water-based glue from the coating box, push the vertical rod to the right. The vertical rod moves the blocking frame inward, completely disaligning the blocking frame with the through holes on the perforated plate. The water-based glue then falls through the perforated plate onto the coating plate, ensuring the uniformity of the water-based glue on the coating plate.

[0021] 3. This utility model incorporates a spring. When the spring is in its naturally extended state, the blocking frame and the through holes on the perforated plate are completely misaligned. The spring force positions the blocking frame, ensuring uniformity during coating. Attached Figure Description

[0030] Example:

[0031] like Figures 1-5 As shown, an embodiment of this utility model provides a water-based adhesive coating mechanism, including a base 1, a mounting plate 2, a lead screw 3, a drive motor 4, a pulley 5, a transmission belt 6, and a coating assembly. Mounting plates 2 are fixedly installed on both the left and right sides of the base 1. A lead screw 3 is rotatably installed between the two mounting plates 2. A drive motor 4 is fixedly installed on the inner end of the right lead screw 3. A pulley 5 is fixedly installed on the outer ends of the two lead screws 3. A transmission belt 6 is sleeved between the two pulleys 5. A coating assembly is spirally connected to the two lead screws 3.

[0032] The coating assembly includes an inverted concave frame 7, a glue storage tank 8, a coating box 9, and a glue pump 10. The two sides of the inverted concave frame 7 are threaded to two lead screws 3 respectively. The glue storage tank 8 is fixedly installed in the center of the upper surface of the inverted concave frame 7. The glue pump 10 is installed at the bottom of the glue storage tank 8. The output end of the glue pump 10 is fixedly equipped with a coating box 9 to ensure uniform coating of glue.

[0033] The coating system is equipped with a lead screw 3, pulley 5, drive belt, and coating assembly. During coating, the material to be coated is placed on the base, water-based adhesive is added to the adhesive storage tank 8, and the adhesive pump 10 is turned on to draw the water-based adhesive into the coating tank 9. Then, the drive motor 4 is turned on, which drives the outer lead screw 3 to rotate. The pulley 5 on the outer lead screw 3 drives the inner pulley 5 to rotate through the drive belt 6, so that the two lead screws 3 rotate in the same direction. The two lead screws 3 drive the inverted concave frame 7 to move left and right. The coating tank 9 coats the material to be coated. The lead screws do not affect the material being placed on the base 1, ensuring convenient coating. Moreover, the single drive motor 4 drives the two lead screws to rotate synchronously, resulting in better coordination and greater energy saving.

[0034] In this embodiment, the coating box 9 includes a coating plate 901, a perforated plate 902, a blocking frame 903, vertical rods 904, and a through groove 905. The coating plate 901 is fixedly installed at the bottom inner side of the coating box 9, the perforated plate 902 is fixedly installed at the center inner side of the coating box 9, the blocking frame 903 is slidably installed above the perforated plate 902, vertical rods 904 are fixedly installed on both the left and right sides of the upper surface of the blocking frame 903, and through grooves 905 are opened on both the left and right sides of the upper surface of the coating box 9.

[0035] In this embodiment, the blocking frame 903 is in the shape of a partition with multiple through slots.

[0036] In this embodiment, the vertical rod 904 passes through the through groove 905.

[0037] In this embodiment, when the vertical rod 904 slides to the innermost side of the through groove 905, the blocking frame 903 is completely misaligned with the through hole on the perforated plate 902, and when the vertical rod 904 slides to the outer end of the through groove 905, the blocking frame 903 completely blocks the through hole on the perforated plate 902.

[0038] In this embodiment, the coating plate 901 has a microporous plate structure, and the bottom horizontal height of the coating plate 901 is lower than the bottom horizontal height of the coating box 9, which facilitates the coating plate 901 to perform coating.

[0039] With the coating box 9 in place, when coating is performed through the coating box 9, first grasp the vertical rod 904 and pull it to the left. The vertical rod 904 moves the blocking frame 903 outward, and the blocking frame 903 completely blocks the through holes on the orifice plate 902. Then, turn on the glue pump 10 to draw the water-based glue from the glue storage tank 8 into the coating box 9. At this time, the water-based glue will not pass through the through holes on the orifice plate 902. When the water-based glue in the coating box 9 covers the orifice plate 902, push the vertical rod 904 to the right. The vertical rod 904 moves the blocking frame 902 inward. At this time, the blocking frame 902 is completely misaligned with the through holes on the orifice plate 902. The water-based glue falls through the orifice plate 902 onto the coating plate 901, ensuring the uniformity of the water-based glue on the coating plate 901.

[0040] In this embodiment, springs 906 are fixedly installed on both the left and right sides of the outer end of the blocking frame 903, and the outer ends of the springs 906 are fixedly installed on the inner side of the coating box 9.

[0041] In this embodiment, when the spring 906 is in its naturally extended state, the blocking frame 903 is completely offset from the through hole on the perforated plate 902, and at this time the vertical rod 904 is at the innermost side of the through groove 905.

[0042] With the spring 906 in place, when the spring 906 is in its natural extended state, the blocking frame 903 is completely misaligned with the through hole on the orifice plate 902. The elastic force of the spring 906 positions the blocking frame 903 to ensure uniformity during coating.

[0043] In this embodiment, the middle width of the inverted concave frame 7 is equal to the width of the base 1, and the inner surface of the inverted concave frame 7 is attached to the left and right sides of the base 1 to ensure the stability of the inverted concave frame 7 when it moves left and right.

[0044] In this embodiment, a frosted rubber layer is adhered to the upper surface of the base 1 to increase the friction of the upper surface of the base 1.

[0045] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
