Description

Technical Field

[0001] The utility model relates to the field of building decoration tools, and is a tool for paving anti-cracking paper tape for ceiling expansion joints. Background Technique

[0002] Ceiling construction is a relatively common construction project in existing building decoration construction. When the area of ceiling construction is large, expansion joints are often required to prevent the ceiling construction surface from cracking due to the influence of building vibration and the like. In the existing construction method of gypsum board ceilings, such as the application publication number CN106337524A published in the Chinese patent literature, the publication date is January 18, 2017, and the invention name is "An installation method for a double-layer paper-faced gypsum board ceiling", which discloses the step of pasting a special paper tape in its installation method, that is, pasting a special joint tape after the expansion joint of the gypsum board ceiling is treated, so as to prevent the expansion joint from cracking. The existing adhesive tapes usually select paper materials such as kraft paper, which do not have self-adhesiveness. It is necessary to first brush glue on the construction surface and then lay the paper tape. This method is obviously more cumbersome in construction. It requires workers to stand at a high position and construct back and forth many times. Moreover, when there are many inside and outside corner positions, it is necessary to repeatedly adjust the construction techniques and states, with a large labor intensity and low overall efficiency. Therefore, it is necessary to improve the existing tools for paving paper tapes for ceiling expansion joints. Summary of the Invention

[0003] To overcome the above deficiencies, the purpose of the utility model is to provide a tool for paving anti-cracking paper tape for ceiling expansion joints to the art, so as to solve the technical problems that the existing tools for paving paper tapes for expansion joints have a single function, a large labor intensity in use, low efficiency, and it is difficult to realize the gluing construction of the paper tape at one time. The purpose is achieved through the following technical solutions.

[0004] A ceiling expansion joint crack prevention paper tape paving tool. The main body of the paving tool is a hand-held housing. A glue storage cavity and a paper tape cavity for placing a paper tape roll are arranged inside the housing. A glue inlet corresponding to the glue storage cavity is arranged on the side surface of the housing. One end of the housing is provided with a paper tape outlet. It is characterized in that a damping roller shaft for axially connecting the paper tape roll is arranged in the middle of the paper tape cavity inside the housing. A paper tape channel for leading the paper tape of the paper tape roll in the paper bag cavity to the paper tape outlet is arranged inside the housing. A guide wheel for guiding the paper tape is arranged at a position close to the paper tape roll in the paper tape channel. A pressure roller for guiding the paper tape is arranged at the paper tape outlet. The glue storage cavity is arranged on one side of the paper tape channel, and a discharge port is arranged on one side of the glue storage cavity corresponding to the paper tape channel. A discharge roller is arranged at the discharge port. The discharge roller is in relative sliding and rotation through a wheel shaft cooperating with a corresponding sliding groove of the housing. When the discharge roller slides to one end, the discharge roller is closed with the discharge port. When the discharge roller slides to the other end, a glue outlet is formed between the discharge roller and the discharge port. When the paper tape outlet of the housing faces upward, the glue in the glue storage cavity extrudes the discharge roller under the action of gravity, and the discharge roller is closed with the discharge port. When the paper tape is tensioned and conveyed along the guide wheel and the pressure roller, the paper tape is attached to and extrudes the discharge roller to slide to form the glue outlet, and the discharge roller rotates as the paper tape is conveyed, that is, the glue in the glue storage cavity is discharged along the glue outlet under the drive of the discharge roller and enters the tape surface of the paper tape, forming a state of gluing the paper tape. Through the above structure, automatic gluing is realized when the paper tape is output, so as to meet the requirements of direct paving, eliminating the cumbersome process of repeatedly brushing glue and paving. The paper tape paving construction can be completed at one time, which is relatively convenient and efficient.

[0005] An elastic member for applying an elastic force to the discharge roller in the initial state to form a closure with the discharge port is arranged in the glue storage cavity. Through this structure, it is further ensured that when the paper tape is not in use, the discharge roller and the discharge port are closed to prevent the glue from leaking out, and the use is relatively reliable.

[0006] Mounting posts are integrally arranged at a position of the housing close to the paper tape outlet. The mounting posts are inserted and connected with a guiding and pressing member for guiding and pressing the glued paper tape on the paper tape construction surface, and the inserted part and the mounting posts are locked and fixed through radial locking screws. Through this structure, it is convenient to deal with different paper tape paving construction surfaces, and the operation is relatively time-saving and labor-saving.

[0007] The guiding and pressing member is an external corner guiding and pressing member or an internal corner guiding and pressing member. Through this structure, it is suitable for the paper tape paving when the expansion joint is located at the external corner or internal corner position, and the use is relatively convenient and efficient.

[0008] Stirring steel balls are arranged in the glue storage cavity. Through this structure, it is convenient to stir the glue or judge the remaining amount state of the glue through the sound of the stirring steel balls.

[0009] The glue inlet of the housing is provided with a detachable rubber sealing plug, which facilitates the feeding and sealing operations of the glue inlet.

[0010] The cover is transparent, and through this structure, it is convenient to observe the state of the rubber material and the paper bag roll in the cover, so as to replenish or replace the material in time.

[0011] The cover comprises a shell and a cover, the shell and the cover are locked and fixed by screws or fasteners, and a sealing ring is provided between the shell and the cover to seal the glue storage cavity. This structure facilitates cleaning or maintenance operations of the internal structure.

[0012] The utility model has a handheld structure as a whole, which is easy to hold and use. The paper tape is pulled out and glue is applied automatically at the same time, so direct paving is realized, eliminating the need for repeated brushing of glue for paving. The construction is time-saving and labor-saving, and the efficiency is high. The utility model is suitable for use as a tool for paving paper tapes for various types of suspended ceiling expansion joints, or as an improvement on the structure of similar tools.

Implementation

[0019] The utility model is now further described with reference to the accompanying drawings.

[0020] like Figure 1 - Figure 2As shown in the figure, the main body of the anti-cracking paper tape laying tool for the ceiling expansion joint is a hand-held housing 1. Inside the housing, there is a glue storage chamber 101 and a paper tape chamber 102 for placing the paper tape roll 4. On the side of the housing, there is a glue inlet corresponding to the glue storage chamber. At the glue inlet, a detachable rubber seal plug 7 is provided. At one end of the housing, there is a paper tape outlet. The specific structure is as follows: The housing is composed of a detachable housing body and a cover. The housing body and the cover are locked and fixed by screws or fasteners. And between the housing body and the housing, there is a sealing ring that seals the glue storage chamber. In the middle of the paper tape chamber inside the housing, there is a damping roller shaft 106 for axially connecting the paper tape roll. Inside the housing, there is a paper tape channel 103 that leads the paper tape of the paper tape roll in the paper bag chamber to the paper tape outlet. Near the position of the paper tape roll in the paper tape channel, there is a guide wheel 3 for guiding the paper tape. At the paper tape outlet, there is a roller bracket 104. The roller bracket is axially connected with a pressure roller 2 for guiding the paper tape. The above-mentioned glue storage chamber is arranged on one side of the paper tape channel. And on the side of the glue storage chamber corresponding to the paper tape channel, there is a discharge port. At the discharge port, there is a discharge roller 5. The discharge roller is in relative sliding and rotation through the cooperation of the wheel shaft and the corresponding chute 107 on the inner side of the housing. When the discharge roller slides to one end, the discharge roller closes with the discharge port. This closed state is not a completely sealed state because the glue itself has viscosity and has self-sealing when filling the gap. When the discharge roller slides to the other end, a glue outlet 108 is formed between the discharge roller and the discharge port, that is, the glue overcomes the viscous seal under its own weight to form automatic glue discharge or discharges glue as the discharge roller rotates. Inside the glue storage chamber, there is an elastic member 6 that applies an elastic force to the discharge roller in the initial state to make the discharge roller close with the discharge port. The strength of the elastic member ensures the normal rotation of the discharge roller. The elastic member can also be omitted, and the discharge roller closes with the discharge port under its own weight or the gravity of the glue. When the paper tape outlet of the housing faces the paper tape laying construction surface at the ceiling, that is, when the paper tape outlet is upward, the glue in the glue storage chamber is squeezed by the gravity of the glue or the elastic member to the discharge roller, and the discharge roller remains closed with the discharge port. When the paper tape is tensioned and conveyed along the guide wheel and the pressure roller, the paper tape tension acts on and presses against the discharge roller and slides the discharge roller to form the above-mentioned glue outlet state. And when the paper tape is conveyed, it drives the discharge roller to rotate. The glue in the glue storage chamber is discharged along the glue outlet under the drive of the discharge roller and enters the surface of the paper tape, forming a state of applying glue to the paper tape.

[0021] Near the paper tape outlet of the above-mentioned housing 1, an installation post 105 is integrally provided. The installation post is inserted and sleeved with a guiding and pressing member 8 for guiding and pressing the glued paper tape onto the paper tape construction surface. And the inserted part is locked and fixed with the installation post by a radial locking screw 9.

[0022] As Figure 3 、 Figure 4 shown, the above-mentioned guiding and pressing member 8 is an external corner guiding and pressing member 801 or an internal corner guiding and pressing member 802, corresponding to the construction of pressing the paper tape on the external corner and the construction of pressing the paper tape on the internal corner respectively.

[0023] Furthermore, stirring beads may also be provided in the glue storage cavity 101. The stirring beads are used to stir the glue material to make the glue material uniform. At the same time, when the cover is made of non-transparent material, it is also convenient to judge whether the glue material is insufficient by the sound of the stirring beads colliding. Of course, the cover can also be made of transparent material, so that it is easier to observe the use status of the internal glue material and the paper bag roll, facilitating timely replenishment and replacement operations.

[0024] The usage method of the ceiling expansion joint crack-proof paper tape paving tool is as follows: First, open the cover 1, axially connect and rotate the paper bag roll 4 with the damping roller shaft 106, pull a section of the paper tape through the guide wheel 3, and extend it along the paper tape channel 103 to the paper tape outlet. Then close the cover, that is, the housing and the cover are buckled or fixed by hand-tightening screws. Then, replenish the glue material through the glue inlet of the cover, and after completion, tighten and fix it with the rubber sealing plug 7. When in use, select the corresponding usage status according to the position of the expansion joint. For example, when the position of the expansion joint is a plane, there is no need to rely on the guiding and pressing member 8, and only rely on the pressing roller shaft 2 to guide and flat-press the paper tape to achieve the paving construction of the paper tape. When the position of the expansion joint is a yang corner or a yin corner, use the corresponding yang corner guiding and pressing member 801 or yin corner guiding and pressing member 802 to achieve the paper tape paving construction at the yang corner and the yin corner. And during construction, still use the pressing roller shaft to guide the output of the paper tape to prevent the problem that the paper tape is easily pulled and broken. When the paper tape is tensioned and conveyed, the tape surface of the paper tape contacts the discharging roller to form extrusion, and the extrusion force makes the discharging roller 5 slide along the chute 107 of the cover to the state of forming the glue outlet 108. At this time, the discharging roller rotates when the paper tape is conveyed, and the glue material in the glue storage cavity is taken out of the glue outlet and sent to the tape surface of the paper tape along the roller surface of the discharging roller during rotation, realizing the automatic gluing operation. After the paper tape is sent out from the paper tape outlet, it can be directly paved and used on the construction surface, which is relatively convenient and efficient. After the paving tool is used, it is necessary to promptly disassemble and clean the housing and the cover for the next use.

[0025] The above content is intended to illustrate the technical means of the present invention and does not limit the technical scope of the present invention. Obvious improvements or replacements made by those skilled in the art to the present invention in combination with the existing common general knowledge also fall within the protection scope of the claims of the present invention.
