Detailed Description

The adhesive tape provided by the invention is divided into two types, wherein one type of adhesive tape is an adhesive tape with an adhesive substance on only one side, and the other type of adhesive tape is an adhesive tape with adhesive substances on both sides. In the case of an adhesive tape having an adhesive substance on only one side, the laying device disclosed in the present invention is only required to change the adhesive tape from a wound state to a laid state and press it against an area where the adhesive tape is to be laid, and in the case of an adhesive tape having an adhesive substance on both sides, since such an adhesive tape has a double-sided adhesive layer and a separator layer separating the double-sided adhesive layer so as not to adhere to each other, the laying device disclosed in the present invention is required not only to change the double-sided adhesive layer of the adhesive tape from a wound state to a laid state and press it against an area where the adhesive tape is to be laid but also to peel off the corresponding separator layer in synchronization and wind it around another rotating mechanism.

The laying device of the present invention can wind the adhesive tape directly around the following rotating mechanism. However, the adhesive tape is usually a finished product of a roll commercially available, that is, the adhesive tape is usually referred to as an adhesive tape wound on a tape roll (or tape roll).

Fig. 1 shows a laying device 100 for laying adhesive tape. Paving device 100 includes a frame 102, a first rotating mechanism 104, a second rotating mechanism 106, a conforming mechanism 108, and a guide 110.

Referring to fig. 2-5, wherein fig. 2 schematically illustrates a perspective view of first rotation mechanism 104 of the paving apparatus, fig. 3 illustrates a front view of first rotation mechanism 104 of fig. 2, fig. 4 illustrates a cross-sectional view taken along line a-a of fig. 3, and fig. 5 illustrates an exploded view of first rotation mechanism of fig. 2. The first rotating mechanism 104 is accommodated in the housing 114 and rotatably mounted on the frame 102, and has a drive disk portion 120 and a first bearing portion 122 protruding from the drive disk portion 120. The drive disc portion 120 is uniformly arranged with gear teeth in a circumferential direction thereof, and the first carrier portion 122 is a cylinder having a cavity 124, and four radial through holes 126 are arranged on the cylinder, and a difference of 90 ° is provided between every two radial through holes in the circumferential direction. The end of the cylinder is provided with three threaded holes 128.

The shaft 130 rotatably secures the first bearing portion 122 to the frame 102 via a washer 134 and a nut 136. The shaft 130 is also recessed with a hexagonal recess 132.

The positioning member 138 is an annular cylinder provided at one end portion with a threaded through-hole 141 penetrating the end portion and formed at the other end portion with a flange 142, four radial through-holes 144 are formed at positions corresponding to the four radial through-holes 126 of the first bearing portion 122 on the annular cylinder, and three through-holes 146 are formed on the flange 142. The positioning member 138 is receivable in the cavity 124 of the first bearing portion 122 such that the four radial through holes 144 of the positioning member 138 are aligned with the four radial through holes 126 of the first bearing portion 122, and the flange 142 of the positioning member 138 abuts against an end of the first bearing portion 122 and such that the three through holes 146 of the flange 142 are aligned with the three threaded holes 128 of the first bearing portion 122.

Each of the four radial engagement members 148 has a shape that conforms to the shape of the radial through bore 144, each radial engagement member 148 having an abutment surface 150 at a first end and an arcuate shape formed at a second end for facilitating abutment with an axial engagement member as described below. Specifically, the radial engagement member 148 is a cylindrical pin and the abutment surface 150 is a pin cap integrally formed proximate the end of the cylindrical pin.

The four elastic members 152 are respectively sleeved on the radial joint member 148. When the four elastic members 152 pass through the radial through holes 144 and 126 of the positioning member 138 and the first bearing portion 122, respectively, one end of the elastic member 152 abuts against the abutting surface 150 of the radial engaging member 148 and the other end abuts against the inner wall of the positioning member 138.

The one-way control mechanism 160 is designed to prevent the adhesive tape that has been applied to the work surface from being peeled off again.

Referring to fig. 6-9, wherein fig. 6 schematically illustrates a perspective view of the second rotation mechanism 106 of the paving apparatus, fig. 7 illustrates a front view of the second rotation mechanism 106 of fig. 6, fig. 8 illustrates a cross-sectional view taken along line B-B of fig. 7, and fig. 9 illustrates an exploded view of the second rotation mechanism of fig. 6. The second rotation mechanism 106 is housed in a housing 114 'and rotatably mounted to the frame 102, and has a driven wheel disk portion 120' and a second bearing portion 122 'projecting from the driven wheel disk portion 120'. The driven disc portion 120 'is uniformly arranged with gear teeth in a circumferential direction thereof, the gear teeth thereof being engaged with the gear teeth of the driving disc portion 120, and the second bearing portion 122' is a cylinder having a cavity 124 ', the cylinder of which is arranged with four radial through holes 126', each two of which are different by 90 ° in the circumferential direction. The end of the post is provided with three threaded holes 128'.

The shaft 130 'rotatably secures the second bearing portion 122' to the frame 102 via a washer 134 'and a nut 136'. The shaft 130 'is also recessed with a hexagonal recess 132'.

The positioning member 138 'is an annular cylinder provided at one end with a flange 142' formed through the end threaded through-hole 141 'at the other end, and four radial through-holes 144' formed at positions corresponding to the four radial through-holes 126 'of the second bearing portion 122' on the annular cylinder, and three through-holes 146 'formed on the flange 142'. The positioning member 138 'is receivable in the cavity 124' of the second bearing portion 122 'such that the four radial through holes 144' of the positioning member 138 'are aligned with the four radial through holes 126' of the second bearing portion 122 ', while the flange 142' of the positioning member 138 'abuts the end of the second bearing portion 122' and aligns the three through holes 146 'of the flange 142' with the three threaded holes 128 'of the second bearing portion 122'.

Each of the four radial engagement members 148 'is shaped to conform to the shape of the radial through bore 144', each radial engagement member 148 'having an abutment surface 150' at a first end and an arcuate shape formed at a second end to facilitate abutment with an axial engagement member as described below. In particular, the radial engagement member 148 'is a cylindrical pin and the abutment surface 150' is a pin cap integrally formed proximate the end of the cylindrical pin.

Four elastic members 152 'are respectively fitted over the radial engagement members 148'. When the four elastic members 152 ' pass through the radial through holes 144 ' and 126 ' of the positioning member 138 ' and the second bearing portion 122 ', respectively, one end of the elastic member 152 ' abuts against the abutting surface 150 ' of the radial engaging member 148 ' and the other end abuts against the inner wall of the positioning member 138 '.

Since the roll of release layer to be wound with adhesive tape from the first rotating mechanism is fitted over the second carrier part 122 ', the roll of adhesive tape is further clamped to the second carrier part 122 ' as the boss 154d ' is tightened. Accordingly, the positioning member 138 ', radial engagement member 148', resilient member 152 ', and axial engagement member 154' described above, among others, may be referred to as a tensioner.

Referring to fig. 10 and 11, wherein fig. 10 schematically illustrates a perspective view of a conformable mechanism of a paving apparatus, and fig. 11 illustrates a partially exploded view of the conformable mechanism of fig. 10. The attachment mechanism 108 is comprised of a mounting plate 166, two inverted U-shaped frames 168, and four springs 170. The attachment plate 166 is formed by welding horizontal and vertical plate portions and is secured to the frame 102, such as by bolts. The horizontal plate portion has four vertical through holes 172 and the vertical plate portion has two vertical grooves 174. Each inverted U-shaped frame 168 is composed of two leg plates 168a and a connecting plate 168b fixed between the two leg plates 168a, wherein one leg plate 168a is convexly provided with two transverse pins 168c, the connecting plate 168b is provided with two vertical columns 168d, and the upper ends of the vertical columns 168d are provided with transverse pin holes. The springs 170 are all mounted on the vertical posts 168d, and during assembly, the vertical posts 168d are inserted through the vertical through holes 172 and the pins are inserted through the transverse pin holes, so that the inverted U-shaped frame 168 is connected to the fixed plate 166, and the transverse pins 168c on the leg plates 168a are inserted into the vertical grooves 174, so that the springs 170 are in a compressed state. A pivot pin 176 is also laterally fixed to the distal end of the two leg plates 168a, and a layer of elastomer may be attached to the outside of the pivot pin 176. Since the entire inverted U-shaped frame 168 can move in the vertical direction under the action of the pressure, and the spring 170 can restore the inverted U-shaped frame 168 to its original shape after the pressure disappears, the attaching mechanism 108 also has a buffer function in the case where the construction surface is not flat.

A guide 110 is secured to the bottom of the frame 102 to support and move the frame 102 over the work surface and is configured to cause the conforming mechanism 108 to conform a respective double-sided adhesive layer of a portion of adhesive tape from the first rotating mechanism 104 to the work surface.

Before the laying device 100 works, a user needs to sleeve the adhesive tape cylinder on the first bearing part 122 of the first rotating mechanism 104 and simultaneously sleeve the empty adhesive tape cylinder on the second bearing part 122' of the second rotating mechanism 106; the tension degree of the adhesive tape cylinder is adjusted through the bosses 154d and 154 d' respectively; after the adjustment is completed, the release layer of the short segment of adhesive tape can be wound around the rotating pin 176 of the attaching structure 108 on the empty adhesive tape cartridge on the second bearing part 122', and simultaneously, the double-sided adhesive layer of the short segment of adhesive tape is attached to the construction surface around the rotating pin 176 of the attaching structure 108; after the preparation, the laying device 100 can be pushed to advance to enter the working state, at this time, since the rotation pin 176 presses the double-sided adhesive layer and the construction surface have strong adhesive force, the driving disc portion 120 of the first rotation mechanism 104 is driven to rotate counterclockwise so as to further peel off the double-sided adhesive layer of the adhesive tape, and meanwhile, the driven disc portion 120' of the second rotation mechanism 106 is driven by the driving disc portion 120 to rotate clockwise so as to wind up the isolation layer of the adhesive tape.

It will be appreciated by those skilled in the art that it is also possible to arrange three radial through holes or more than four radial through holes in the first carrier part, so that it is desirable to reduce or increase the number of corresponding radial engagement members and resilient members.

It will be appreciated by those skilled in the art that the foregoing describes a preferred embodiment of the invention, namely the application of a double-sided adhesive tape having a barrier layer and a double-sided adhesive layer to a construction surface, however, as previously mentioned, the invention may also be applied to construction surfaces having an adhesive on only one side. It is clear that, for the laying device for such tapes, the simpler solution is to omit the aforementioned second rotating mechanism, without modifying other structures, and therefore, the description thereof is not repeated.

It will also be appreciated by those skilled in the art that a guide is not essential, as the pivot pin in the abutment mechanism may also double as a guide.

The laying device of the invention is shown in fig. 1 as being able to lay two tapes simultaneously, however, it is fully possible for a person skilled in the art to adapt it to the actual requirements, for example, to lay three, four, five or more tapes, or, more clearly, to lay only one tape.

In the light of the above embodiments, it is clear that the designer skilled in the art can fully design the invention to be electrically driven, i.e. the advancement of the device is performed by means of, for example, a motor.

The invention is not limited in any way to the exemplary embodiments presented in the description and the drawings. All combinations of (parts of) the embodiments shown and described are explicitly understood to be incorporated within this description and are explicitly understood to fall within the scope of the invention. Also, many variations are possible within the scope of the invention as outlined by the claims.
