Description

Technical Field

[0001] This utility model relates to composite equipment, and in particular to a coating structure for composite equipment. Background Technology

[0002] Paper filter bags are typically made of two layers of composite paper. The composite paper is folded and glued along its two edges to create openings at both ends, which are then sealed to form an inner cavity. One side of the composite paper has holes for connectors to be installed. These connectors are used to connect to appliances such as vacuum cleaners and air purifiers. Air passes through the paper filter bag, and dust particles are trapped inside. The composite paper usually consists of an outer layer of fiber paper and an inner layer of filter paper, which are bonded together using a laminating machine. Because filtration is required, the adhesive coating system only applies glue to the two edges of one layer of paper during the bonding process. This results in unstable bonding between the fiber paper and the filter paper after the composite paper is processed into a paper filter bag. Utility Model Content

[0015] Please see Figure 1 and Figure 2 A coating structure for a composite device includes: a mounting part 1, a glue box 2, a coating roller 3, a coating block 4, and a drive part 5.

[0016] Mounting part 1 has two mounting positions 1A. More specifically, mounting position 1A is a bearing seat for subsequent rotational connection of the coating roller 3.

[0017] The glue box 2 is fixedly connected to the mounting part 1. More specifically, the mounting part 1 can be concave, and the glue box 2 is fixedly connected at the concave opening. The two mounting positions 1A are located on both sides of the concave opening.

[0018] A first roller 2A and a second roller 2B are rotatably connected to the top opening of the glue box 2. More specifically, both ends of the first roller 2A and the second roller 2B can be stepped, and they are rotatably connected to the side plate of the glue box 2 via bushings. The first roller 2A and the second roller 2B are in contact, meaning that they can rotate together through friction. The first roller 2A is relatively lower, meaning it directly contacts the glue inside the glue box 2; the second roller 2B is relatively higher, meaning it does not directly contact the glue inside the glue box 2, but through contact with the first roller 2A, a portion of the glue adhering to the first roller 2A is transferred to the second roller 2B.

[0019] The coating roller 3 is rotatably connected to two mounting positions 1A. More specifically, the two ends of the coating roller 3 can be stepped, inserted into the inner ring of the bearing in the bearing housing, with the shoulder abutting against the inner ring to complete the connection and positioning. The surface of the coating roller 3 also has two annular protrusions 3A.

[0020] The glue-applying block 4 is fan-shaped. The glue-applying block 4 is detachably connected to the glue-applying roller 3 between the two annular protrusions 3A. More specifically, the glue-applying block 4 can be connected to the glue-applying roller 3 using countersunk screws, with the glue-applying block 4 having a countersunk hole and the glue-applying roller 3 having a threaded hole; the glue-applying block 4 can also be connected to the glue-applying roller 3 using magnetic attraction, with the glue-applying block 4 having a magnet embedded in its inner wall; or the glue-applying block 4 can be connected to the glue-applying roller 3 using adhesive, with cardboard, rubber, etc., used as the glue-applying block 4.

[0021] The drive unit 5 for the second roller 2B can switch between the following two states: contact state with the annular protrusion 3A and the adhesive block 4, and separation state with the annular protrusion 3A and the adhesive block 4.

[0022] In the gluing structure of the laminating equipment, the paper to be glued first passes through a guide roller 6, then through a gluing roller 3, and finally through another guide roller 6. The two guide rollers 6 create an envelope angle on the gluing roller 3. The friction of the paper as it passes through can be used to drive the rotation of the gluing roller 3, the first roller 2A, and the second roller 2B; alternatively, one of the three rollers can be selected as the driving roller and a motor can be added to drive its rotation. When the gluing roller 3 and the gluing block 4 need to be replaced, the second roller 2B may interfere. The drive unit 5 moves the gluing roller 3 or the glue box 2, thereby separating the second roller 2B from the gluing roller 3.

[0023] Please see Figure 2In some embodiments, the fixed position between the glue box 2 and the mounting part 1 can be adjusted vertically, that is, the drive part 5 drives the glue box 2 to move, thereby separating the second roller 2B and the glue application roller 3. The drive part 5 is a lifting screw mechanism, which is disposed between the mounting part 1 and the glue box 2.

[0024] More specifically, a set of optical shafts 52 can be fixedly connected to the bottom surface of the glue box 2, and a bushing matching the optical shafts 52 can be fixedly connected to the mounting part 1. The lifting screw mechanism can be in the form of a fixed screw 51, and the top of the screw 51 can have a flange to be fixedly connected to the bottom surface of the glue box 2.

[0025] Please see Figure 6 Based on the above embodiment where "the fixed position between the glue box 2 and the mounting part 1 can be adjusted vertically," in some embodiments, a gear 3B is fixedly connected to one end of the glue applicator roller 3. A retaining tooth 1B is slidably connected to the mounting part 1 vertically. More specifically, the retaining tooth 1B can be fixedly connected to a first linear guide, and a first mounting slider matching the first linear guide can be fixedly connected to the mounting part 1. A connecting rod member 7 is provided between the retaining tooth 1B and the glue box 2. That is, when the glue box 2 is adjusted to the fixed connection position of the mounting part 1, the retaining tooth 1B slides vertically up and down by the vertical sliding of the glue box 2. When the second roller 2B is in contact, the retaining tooth 1B is separated from the gear 3B, meaning that the retaining tooth 1B will not interfere with the rotation of the glue applicator roller 3 at this time. When the second roller 2B is in separation, the retaining tooth 1B can engage with the gear 3B, meaning that the retaining tooth 1B restricts the rotation of the glue applicator roller 3 at this time.

[0026] More specifically, the locking tooth 1B can be located below the gear 3B. The glue box 2 slides downwards, the locking tooth 1B moves upwards, the glue box 2 slides upwards, and the locking tooth 1B moves downwards. Correspondingly, the connecting rod component 7 can include: a first connecting rod 71, a sliding block 72, and a second connecting rod 73. The sliding block 72 is horizontally slidably connected to the mounting part 1. The upper end of the first connecting rod 71 is hinged to the locking tooth 1B, and the lower end is hinged to the sliding block 72. The upper end of the second connecting rod 73 is hinged to the sliding block 72, and the lower end is hinged to the outer wall of the glue box 2.

[0027] The drive unit 5 moves the glue box 2, causing the second roller 2B and the glue application roller 3 to separate. At the same time, it works in conjunction with the connecting rod component 7 to move the locking tooth 1B, thereby restricting the rotation of the glue application roller 3, which makes it easier to adjust or replace the glue application block 4.

[0028] Please see Figure 4In some embodiments, the coating roller 3 includes a roller body 31, two connecting blocks 32, and a bidirectional lead screw 33. The roller body 31 is hollow. More specifically, the roller body 31 may include a cylindrical portion 311 and two shaft end portions 312. The two shaft end portions 312 can be flanged to both sides of the cylindrical portion 311, thereby forming a hollow roller body 31. Two annular protrusions 3A are sleeved on the roller body 31. The two connecting blocks 32 are axially slidably connected inside the roller body 31 and also connect the two annular protrusions 3A respectively. More specifically, the connecting blocks 32 and the two annular protrusions 3A can be connected by magnetic attraction, or two axial gaps 3C can be provided in the roller body 31, through which the connecting blocks 32 and the annular protrusions 3A can be directly fixed together. The bidirectional lead screw 33 is rotatably connected to the roller body 31. More specifically, the two shaft end portions 312 can be equipped with bearings for the rotatable connection of the bidirectional lead screw 33. Two lead screw nuts are fixedly connected to two connecting blocks 32 respectively. One of the shaft end portions 312 may have a through hole, and the end of the bidirectional lead screw 33 in the through hole may have an internal hexagonal hole, which drives the bidirectional lead screw 33 to rotate.

[0029] When the paper width changes, the rotation of the restrictor roller 31 is controlled, and the bidirectional lead screw 33 is rotated, thereby driving the two annular protrusions 3A to move axially and adjust their positions to adapt to the paper. The glue coating block 4 is also replaced or its position adjusted simultaneously. Compared to replacing the glue coating roller 3, the operation is more convenient.

[0030] Please see Figure 4 and Figure 5 Based on the above embodiment of "the coating roller 3 includes: roller body 31, two connecting blocks 32 and bidirectional lead screw 33", in some embodiments, the connection between the connecting block 32 and the annular protrusion 3A is selected by setting two axial gaps 3C in the roller body 31. The connecting block 32 includes: a mounting block 321 and two insert blocks 322 that extend and retract from the mounting block 321. That is, the mounting block 321 is used for the lead screw nut to be fixedly connected, and the insert blocks 322 are used to connect with the annular protrusion 3A. More specifically, the mounting block 321 may have two notches, and the insert blocks 322 are connected to the notches. The insert blocks 322 are also provided with fasteners 323. When the fasteners 323 are tightened, the insert blocks 322 are relatively fixed to the mounting block 321. The inner wall of the annular protrusion 3A has two insertion grooves 3A1.

[0031] With the insertion block 322 retracted into the mounting block 321, insert the bidirectional lead screw 33 and two connecting blocks 32 into the cylindrical portion 311 of the roller body 31. Adjust the connecting blocks 32 so that the two mounting blocks 321 correspond to the two gaps 3C respectively. Fit the annular protrusion 3A and adjust the annular protrusion 3A so that the two insertion grooves 3A1 correspond to the two gaps 3C respectively. Extend the insertion block 322 and insert it into the insertion groove 3A1 through the gap 3C. Install the two shaft end portions 312 onto the two ends of the cylindrical portion 311 respectively.

[0032] Please see Figure 5 Based on the above embodiment of "the coating roller 3 includes: roller body 31, two connecting blocks 32 and bidirectional lead screw 33", in some embodiments, the inner wall of the coating block 4 has a snap-fit ​​protrusion 4A, which snaps into one of the gaps 3C. Replacing the coating block 4 is more convenient.
