[0035] The present invention provides an auxiliary pasting device for coating masking tape, such as Figure 1 and Figure 2 As shown, the auxiliary pasting device for coating masking tape comprises: an L-shaped main frame 100, which is composed of vertical bars and horizontal bars connected to each other, and serves as the main structure of the auxiliary pasting device for coating masking tape; a telescopic component 200, which is arranged at one end of the vertical bar of the main frame 100 away from the horizontal bar, so as to adjust the height of the telescopic component 200 according to the height of the operator; two first connecting shafts 500, which are symmetrically arranged on two opposite first side walls of the vertical bar; and a plurality of second connecting shafts 700, which are symmetrically arranged on two opposite second side walls of the horizontal bar and are parallel to the first connecting shafts 500; Two masking tape fixing sleeves 600 are rotatably mounted on the annular outer wall of the first connecting shaft 500 to place the masking tape; a plurality of rolling blocks 800 are rotatably arranged outside the second connecting shaft 700 to wind the masking tape, and the masking tape is adhered to the hull surface by rotating the rolling blocks 800 on the hull surface; a magnetic attraction component 900 is arranged on the bottom of the cross bar of the main frame 100 close to the hull surface, so that the magnetic attraction component 900 and the hull surface are magnetically attracted to each other, thereby replacing the human labor of pressing down the pasted masking tape.

[0036] Among them, the vertical rod of the main frame 100 is a hollow rectangular structure, and a top screw 101 is provided on the vertical rod; the top screw 101 includes: a hand-tightening end and a stud end connected to the hand-tightening end; the stud end is used to contact and tightly press against the telescopic component 200, and the hand-tightening end is used to rotate the top screw 101 inward to fix the telescopic component 200.

[0037] Furthermore, the telescopic component 200 is a long rectangular rod, one end of the telescopic component 200 extends into the hollow vertical rod, and the other end extends out of the vertical rod; two hand-pushing components 300 are provided at the top end of the telescopic component 200 extending out of the vertical rod; the two hand-pushing components 300 are symmetrically arranged on two opposite third side walls of the telescopic component 200 in a direction perpendicular to the vertical rod, and are used for hand pushing during operation.

[0038] Specifically, one end of the long rod extends out of the vertical rod of the main frame 100, and the other end of the long rod is inserted into the vertical rod of the main frame 100, and can move up and down along the vertical rod to adjust the height of the telescopic component 200 relative to the operator on the hull. The bolt end of the top screw 101 is set close to the fourth side wall of the long rod close to the top screw 101, and the hand-tightening end is rotated inward to make the bolt end close to the fourth side wall of the long rod close to the top screw 101, and then after adjusting the extension distance of the long rod according to the height of the operator, the long rod is fixed in a certain extension position.

[0039] In a specific embodiment of the present invention, four second connecting shafts 700 are used, two of which are spaced apart on one side of two opposite second side walls of the crossbar, and the other two are spaced apart on the other side of two opposite second side walls of the crossbar. Accordingly, four rolling blocks 800 are used, which are rotatably arranged outside the second connecting shafts 700.

[0040] Furthermore, the two rolling blocks 800 located on the forward side, that is, the two rolling blocks 800 close to the masking tape fixing sleeve 600, are used to first wrap the masking tape and adhere the wrapped masking tape to the surface of the hull through the rotation of the rolling blocks 800; the two rolling blocks 800 opposite to the forward side can further roll the masking tape that has been rolled and adhered by the two rolling blocks 800 located on the forward side, so as to achieve a firmer adhesion of the masking tape.

[0041] Among them, the outer cylindrical surface of each of the masking tape fixing sleeves 600 is provided with a plurality of anti-slip strips 601, and the anti-slip strips 601 are arranged at intervals along the rotation direction of the outer cylindrical surface (i.e., arranged along the axial direction of the masking tape fixing sleeve 600), and the anti-slip strips 601 can prevent the masking tape from falling off during use. In a specific embodiment of the present invention, six anti-slip strips 601 are used and are arranged at equal intervals on the outer cylindrical surface of each of the masking tape fixing sleeves 600.

[0042] The bottom end of the magnetic component 900 close to the hull is kept at a certain distance from the hull surface to prevent the magnetic component 900 from being adsorbed on the hull. Specifically, the bottom end of the magnetic component 900 close to the hull is higher than the bottom end of the rolling block 800 contacting the hull. More specifically, the magnetic component 900 is a magnet.

[0043] The hand-pushing member 300 is disposed at the top of the two opposite third side walls.

[0044] An anti-slip sleeve 301 is provided on the outer cylindrical surface of each of the hand-pushing components 300 to increase the friction force when the operator pushes by hand, so as to push the auxiliary sticking device on the surface of the hull more easily.

[0045] The use process of the auxiliary pasting device for coating masking tape of the present invention is as follows:

[0046] Step S1, adjust and fix the height of the telescopic component 200 by rotating the top screw 101; before use, loosen the top screw 101 to adjust the extended length of the telescopic component 200 to a height that is convenient for the operator to operate, and then tighten the top screw 101 to fix the telescopic component 200 in the extended position.

[0047] Step S2, installing the masking tape on the masking tape fixing sleeve 600, and pulling open one end of the masking tape to wrap around the outer surface of the rolling block 800; respectively sleeve two rolls of masking tape on the two masking tape fixing sleeves 600, pulling open part of the masking tape, so that the pulled masking tape is wrapped around the outer surface of the rolling block 800, and continues to stretch along the rolling block 800 until the starting end of the masking tape is pasted to the starting position on the hull surface to be pasted.

[0048] Step S3, the masking tape is pasted and compacted on the surface of the hull by means of the rolling block 800 and the magnetic component 900; the operator pushes the auxiliary pasting device for applying the masking tape by means of the hand-pushing component 300, and as the rolling block 800 rotates, the masking tape wrapped on the surface of the rolling block 800 is continuously pulled out, spread and pasted on the surface of the hull, and in this process, the suction force generated by the magnetic component 900 on the surface of the hull generates a downward pressure between the rolling block 800 and the hull, and this pressure acts on the masking tape between the hull and the rolling block 800, and finally the masking tape is tightly compacted on the surface of the hull.

[0049] Step S4, continue to push the auxiliary pasting device for applying the masking tape on the surface of the hull through the hand-pushing component 300 until the masking tape is pasted on the surface of the hull.

[0050] In summary, the auxiliary pasting device for coating masking tape provided by the present invention can solve the problems of low pasting efficiency and physical labor consumption in the use of the existing auxiliary pasting device for coating masking tape; specifically, the auxiliary pasting device for coating masking tape can simultaneously realize the pasting of two masking tapes on the surface of the hull, and paste and compact the masking tape through the rolling block 800 and the magnetic suction component 900, which not only improves the pasting efficiency but also reduces manual labor.
