Description

Technical Field

[0001] The invention relates to the field of glass glue pushing devices, in particular to a glass glue pushing device and a pushing method thereof. Background Art

[0002] For prefabricated buildings, traditional silicone and polyurethane sealants have obvious defects. At present, the sealants used for prefabricated building joints tend to be modified silicone (MS) sealants. According to different packaging methods, modified silicone sealants can be divided into barreled sealants, hard packaging sealants and soft packaging sealants (commonly known as sausage glue). These different types of sealants require the use of a glue gun during construction. Barreled glass glue is generally squeezed out by manually squeezing the glue gun. Due to the different manual squeezing forces, the glue output speed is uneven, the glue output is unstable, and it is easy to cause waste. In addition, if the manual squeezing is performed for a long time, the operator is prone to fatigue, which affects work efficiency and needs to be improved urgently. Summary of the invention

[0003] The object of the present invention is to provide a glass glue pushing device to solve the problems raised in the above-mentioned background technology, which has the advantage of stable glue discharge.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a glass glue pushing device, comprising a shell and a fixing mechanism, a driving mechanism and a transmission mechanism are arranged in the shell, the driving mechanism comprises a first gear, the first gear is meshed with a second gear, the transmission mechanism comprises a push rod threadedly connected to the middle part of the second gear, the side of the push rod is provided with a plane symmetrically distributed about the center of the push rod, one end of the push rod is sleeved with a push head, a limit piece for limiting the rotation of the push rod is arranged in the shell, the fixing mechanism comprises a fixing plate arranged on the side of the first shell away from the second shell, the fixing plate is provided with two square grooves penetrating the fixing plate, the fixing plate is connected to a bracket through the square groove, and the fixing plate is penetrated by a through hole for the driving rod to pass through.

[0005] By adopting the above technical solution, the first gear is driven to drive the second gear to rotate. Under the action of the limiter, the push rod will not be able to rotate around its own axis but can only move along its own length direction. After the second gear rotates, it will be able to drive the push rod to move and thus drive the push head to move. Due to the drive of the first gear and the second gear, the push head can only move at a uniform speed so that the push head can evenly squeeze one end of the glue stick to evenly discharge the glue. If there is no push head, the push rod can easily penetrate the plastic parts inside the glue stick during work, causing the glass glue to leak and fail to work. The fixing plate uses a square groove to connect the bracket. Then, when using an external powered device, the powered device can be placed on the bracket to increase the overall stability during use.

[0006] As a further solution of the present invention: a driving rod is connected to the middle of the first gear.

[0007] By adopting the above technical solution, an external hand-held electric drill is used to drive the driving rod to rotate, thereby driving the first gear to rotate, and driving the second gear to rotate, so as to achieve the purpose of facilitating the rotation of the push rod.

[0008] As a further solution of the present invention: the shell includes a first shell and a second shell that are clamped to each other, the first shell includes a through groove for the push rod to pass through, the first shell is provided with a plurality of circular holes distributed about the center of the through groove, the limiting member includes a limiting steel ball in the circular hole, and the limiting steel ball abuts against the plane of the push rod.

[0009] By adopting the above technical solution, the limiting steel ball is restricted by the circular hole and can only be located in the circular hole, and the two limiting steel balls are located on one side of the plane of the push rod, so that the push rod cannot rotate.

[0010] As a further solution of the present invention: connecting rings protruding outward are integrally connected to both sides of the middle part of the second gear, the second gear is provided with a bearing through the connecting ring sleeve, a fixing ring for accommodating the bearing is integrally connected to the side of the first shell facing the second shell, and a receiving groove for accommodating the bearing is provided on the side of the second shell facing the first shell.

[0011] By adopting the above technical solution, the fixing ring and the accommodating groove are used to place the bearing, and the bearing sleeve is arranged outside the connecting ring. The arrangement of the bearing facilitates the rotation of the second gear.

[0012] As a further solution of the present invention: a plurality of fixing rods are integrally connected to a side of the second shell facing away from the first shell, and the push head is provided with fixing grooves for accommodating the fixing rods.

[0013] By adopting the above technical solution, the fixing rod is in the fixing groove, and the cooperation between the two plays a role of pre-fixing the push head.

[0014] As a further solution of the present invention: a plurality of threaded plates are integrally connected to the side of the second shell facing away from the first shell, the second shell is integrally connected to a guide plate on one side of the threaded plate, and an extended circular plate is integrally connected to the side of the threaded plate facing away from the guide plate.

[0015] By adopting the above technical solution, after placing the glue stick on one side of the second shell, the external bolt is threadedly connected to the threaded plate to fix the glue stick. The setting of the extended circular plate facilitates the threaded connection between the external bolt and the threaded plate. If there is no extended circular plate, the bolt will easily shift and fall when placed in the hole. The setting of the guide plate can guide the external bolt.

[0016] Preferably, the bracket and the fixing plate are both made of metal material.

[0017] Another object of the present invention is to provide a pushing method for a glass glue pushing device, and the pushing method of the glass glue pushing device includes the following steps:

[0018] Step 1: Put the bracket ring on the handle of the external electric device, fasten the open end to the fixing plate with a nut, and connect the electric device to the driving rod bit

[0019] Step 2: The driving rod drives the first gear to rotate, and then drives the second gear to rotate. The second gear drives the push rod to move linearly and then drives the push head to move. During the above process, the limiting steel ball restricts the rotation of the push rod;

[0020] Step 3: The push head moves to push one end of the glue stick connected to the push head.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The first gear is driven to drive the second gear to rotate. Under the action of the limiting member, the push rod cannot rotate around its own axis but can only move along its own length direction. After the second gear rotates, it will be able to drive the push rod to move and then drive the push head to move. Due to the drive of the first gear and the second gear, the push head can only move at a uniform speed, so that the push head evenly squeezes one end of the glue stick to evenly extrude the glue. If there is no push head, the push rod is likely to pierce through the plastic part inside the glue stick during operation, resulting in the leakage of the glass glue and inability to work. The fixing plate uses a square groove to connect the bracket. Then, when using an external power-on device, the power-on device can be placed on the bracket to increase the stability and safety during overall use. Description of the Drawings
