DETAILED DESCRIPTION

[0028] Combination Figures 1 to 6 The content shown in the embodiment discloses a device for uniformly applying glue in a tube, which includes a construction tube 1, a quantitative mold sleeve 2 and a glue extrusion device 3. One end of the construction tube 1 is embedded in the quantitative mold sleeve 2, and one end of the glue extrusion device 3 is embedded in the end of the construction tube 1. The other end of the glue extrusion device 3 extends out of the construction tube 1 and is connected to the quantitative mold sleeve 2. The quantitative mold sleeve 2 controls the amount of adhesive extruded and the path of application by controlling the stroke of the glue extrusion device 3.

[0029] The adhesive containing and extruding device 3 is used for containing, extruding and applying adhesive.

[0030] In some specific implementations,

[0031] The quantitative mold sleeve 2 includes a mold sleeve main body 201, on which a hole piece 202 is arranged corresponding to the construction tube 1, and one side end of the mold sleeve main body 201 in the extension direction of the hole piece 202 is a disc-shaped structure, and an involute groove 203 is arranged on the end face of the side end corresponding to the construction tube 1 and the glue extrusion device 3, such as: the cross-section of the construction tube 1 is circular, the inner diameter of the hole piece 202 is equal to the outer diameter of the construction tube 1, and an involute spiral groove is arranged on the end face of one side end of the disc-shaped structure on the mold sleeve main body 201 corresponding to the hole piece 202. The glue extrusion device 3 includes a handle 301 and a glue extrusion device body, the glue extrusion device body includes a cylinder body 302 and a plunger 303, the cylinder body 302 is provided with a glue storage groove 321 for storing adhesive, one end of the plunger 303 is accommodated on a side of an opening provided on the glue storage groove 321, the other end of the plunger 303 is provided with an extrusion end, the extrusion end is provided with a groove, and the groove is provided with a glue outlet 332, the plunger 303 is provided with an extrusion channel 331, one end of the extrusion channel 331 is connected to the glue outlet 332, and the other end of the extrusion channel 331 is connected to the glue storage groove 321. The handle 301 is in the shape of a mountain. The extension section in the middle of the handle 301 is connected to the outer wall of the cylinder body 302. The extension sections on both sides of the handle 301 form positioning hooks, which correspond to the groove 203. The ends of the positioning hooks are embedded in the groove 203 and can move along the groove 203 to achieve the purpose of controlling the cylinder body 302 to drive the plunger 303 to travel.

[0032] The quantitative die sleeve 2 may be provided with a spare through hole 204 corresponding to the hole piece 202. Bolts may be arranged through the spare through hole 204, and the ends of the bolts may be screwed to abut against the outer wall of the construction pipe 1 to enhance the stability of the quantitative die sleeve 2 during application.

[0033] The quantitative die sleeve 2 can also be applied to non-circular objects, and it is only necessary to open holes and grooves according to the shape of the object.

[0034] The groove wall of the above-mentioned glue groove 321 is adapted to the outer side wall of the plunger 303, and a sealing component (such as a sealing ring, etc., which is generally installed at the rear end of the plunger 303, that is, the end of the plunger 303 inserted into the glue groove 321) can be installed between the groove wall of the glue groove 321 and the plunger 303 to enhance the sealing effect between the plunger 303 and the groove wall of the glue groove 321, so as to prevent the adhesive from leaking through the gap between the groove wall of the glue groove 321 and the outer side wall of the plunger 303 during the extrusion process.

[0035] A guide block 304 may be added to the front end of the cylinder body 302 (the front end of the cylinder body 302 is the end close to the opening of the adhesive holding groove 321), and a track groove 334 adapted to the guide block 304 may be added to the plunger 303. The bottom of the guide block 304 is embedded in the track groove 334 and can slide along the track groove 334. The design of the guide block 304 and the track groove 334 can guide and limit the operation of the plunger 303, and prevent the plunger 303 from rotating during the sliding process, so that the operation of the plunger 303 is more stable and reliable, thereby providing a guarantee for the effect of applying glue. Here, bolts or the like can be selected as guide blocks 304 to form a detachable connection between the guide blocks 304 and the cylinder body 302. One end of the bolt passes through the cylinder body 302 and extends into the track groove 334. By unscrewing the bolt, the plunger 303 can be separated from the cylinder body 302 by pulling. After the plunger 303 is inserted into the cylinder body 302, the bolt can be screwed so that one end of the bolt passes through the cylinder body 302 and extends into the track groove 334 to complete the assembly of the plunger 303 and the cylinder body 302. This facilitates better cleaning of the plunger 303 and the cylinder body 302, and facilitates operations such as replenishment and replacement of adhesives.

[0036] The shape and depth of the groove correspond to the shape and thickness of the adhesive to be applied, and bumps 333 are provided on both sides of the groove, and the connecting line of the two bumps 333 is parallel to the wall of the construction pipe 1. During the application of the device for uniformly applying glue inside the pipe, the outer wall of the bump 333 contacts the inner wall of the construction pipe 1.

[0037] The extension section in the middle of the handle 301 and / or the extension sections on both sides of the handle 301 may be telescopic rods controlled by electric / hydraulic / pneumatic forces, so as to meet the coating requirements of different depths in the construction pipe 1.

[0038] The working principle of the uniform glue spreading device in the pipe described in this embodiment can be as follows:

[0039] Insert the end of the construction tube 1 to be coated with adhesive into the hole 202 of the quantitative mold sleeve 2, then insert the main body of the glue extrusion device into the construction tube 1, and insert the positioning hooks on both sides of the handle 301 into the corresponding grooves 203. At this time, the protrusions 333 on the plunger 303 are just in contact with the inner wall of the construction tube 1, and the adhesive is squeezed to the glue outlet 332. Rotate the handle 301 in one direction, and the positioning hooks at both ends will move radially and uniformly along the involute groove 203 on the quantitative mold sleeve 2, while driving the main body of the glue extrusion device to move. Under the action of the plunger 303, the adhesive in the cylinder 302 is squeezed, and a certain amount of extruded adhesive is smeared on the inner wall of the tube. After one rotation, the glue outlet 332 returns to its original position, leaving a uniform adhesive on the inner wall of the tube, thereby achieving uniform coating of the adhesive.

[0040] The above undisclosed matters can be directly implemented by existing technologies, so they will not be elaborated here. The above-mentioned tube uniform glue spreading device can not only realize the uniform application of adhesive in the tube, but also realize the application of other colloid substances, cement, etc. in other regular or irregular objects. The above is only the preferred mode of the utility model. It should be pointed out that for ordinary technicians in this field, several similar deformations and improvements can be made without departing from the creative concept of the utility model, which should also be regarded as the protection scope of the utility model.
