Description

Technical Field

[0001] This utility model relates to the field of equipment and tooling technology, specifically a handheld template cleaning tool. Background Technology

[0002] A handheld formwork cleaning tool is a device used for cleaning formwork. It is mainly used in the manufacturing of prestressed concrete cylinder pipes for cleaning formwork. In water conservancy projects, PCCP pipe manufacturing requires the use of formwork to pour concrete. When using the formwork, a release agent needs to be sprayed to ensure that the surface of the pipe core concrete is smooth after demolding. However, in actual production, due to operator problems, concrete or other residues may accumulate on the formwork, causing the surface of the pipe core to have pitting, sticking, and other phenomena after demolding. A handheld formwork cleaning tool is needed to grind and clean the formwork.

[0003] When cleaning templates, handheld template cleaning tools generate very fine and lightweight dust particles that are easily suspended in the air. When a large amount of dust is generated, it forms a "dust fog" in the operating area. The large amount of dust generated during template cleaning scatters and reflects light, interfering with the propagation of light. In this environment, the operator's vision is obstructed by the pervasive dust, making it difficult to see the template surface and the surrounding environment, thus affecting the accuracy and efficiency of the operation.

[0004] Therefore, a handheld template cleaning tool is proposed to address the above problems. Utility Model Content

[0025] Please see Figure 1-5This utility model provides a technical solution:

[0026] A handheld template cleaning tool includes a grinding disc 1, a motor 2, and a pin 3. The motor 2 is mounted on the upper end of the fixed head of the grinding disc 1. The pin 3 is located on the inner side of the upper end of the motor 2. A support rod 4 is rotatably connected to the outer side of the pin 3. A handheld auxiliary handle 5 is fixedly connected to the outer side of the support rod 4 by welding. A dust removal device 6 is mounted on the outer side of the support rod 4. The dust removal device 6 includes a vacuum cleaner 61. A connecting pipe 62 is fixedly connected to the lower end of the vacuum cleaner 61, and a dust bin is fixedly connected to the lower end of the connecting pipe 62. 63. A dust collection pipe 64 is fixedly connected to the upper end of the dust bin 63. A mounting shell 65 is fixedly connected to the other end of the dust collection pipe 64. A dispersing net 66 is fixedly connected to the inner side of the mounting shell 65. A conveying pipe 67 is fixedly connected to the bottom of the mounting shell 65. A dust collection ring 68 is fixedly connected to the lower end of the conveying pipe 67. The dust collection ring 68 includes a ring body 681. A dust collection pipe 682 is opened on the inner side of the ring body 681. A connecting groove 683 is opened on the inner side of the ring body 681. A dust collection hole 684 is opened on the outer side of the ring body 681.

[0027] As a further implementation of the above technical solution: two suction pipes 682 are provided, which are symmetrically arranged inside the ring 681. The suction pipes 682 are ring-shaped and parallel to each other, so that the suction force from the delivery pipe 67 can be further evenly distributed.

[0028] As a further implementation of the above technical solution: the center points of the mounting shell 65 and the dispersing net 66 are located on the same vertical line. Both the mounting shell 65 and the dispersing net 66 are annular. The dispersing net 66 is installed inside the mounting shell 65 by a snap-fit ​​mechanism. The dispersing net 66 is located in the middle of the mounting shell 65. The dispersing net 66 is installed in the middle of the inner side of the mounting shell 65 by a snap-fit ​​mechanism, which can evenly distribute the suction force, ensure consistent dust collection effect around the grinding disc 1, and improve dust collection efficiency.

[0029] As a further implementation of the above technical solution: four connecting slots 683 are provided. The vertical cross-section of the connecting slots 683 is square. The connecting slots 683 connect to two suction pipes 682. The connecting slots 683 communicate with the inside of the conveying pipes 67. The connecting slots 683 and the conveying pipes 67 correspond one-to-one. A high-efficiency suction system is formed by the suction pipes 682, the connecting slots 683 and the suction holes 684.

[0030] As a further implementation of the above technical solution: four delivery pipes 67 are provided, the inner side of the delivery pipes 67 is connected to the inner side of the mounting shell 65, and the delivery pipes 67 are arranged in a circular array with the vertical line of the mounting shell 65 as the axis. The delivery pipes 67 are all perpendicular to the bottom of the mounting shell 65, and the mounting shells 65 are parallel to each other. This can effectively transfer the evenly dispersed suction force to the suction ring 68, ensuring uniform suction force in all parts.

[0031] As a further implementation of the above technical solution: the vacuum cleaner 61 is installed on the outside of the support rod 4, the mounting shell 65 is installed on the bottom of the motor 2 and the outside of the grinding disc 1, and the dust suction ring 68 is set around the grinding disc 1 to suck the dust generated during the grinding process into the dust bin 63, preventing dust from spreading in the working environment and protecting the health of the operators;

[0032] As a further implementation of the above technical solution: a number of dust suction holes 684 are provided. The dust suction holes 684 are cylindrical and are evenly and equidistantly distributed on the upper and lower sides of the ring body 681. The dust suction holes 684 are connected to the inner side of the dust suction pipe 682 and are parallel to each other, which can effectively capture the dust generated during the polishing process and ensure the cleanliness of the working environment.

[0033] Workflow: The operator holds the handheld auxiliary handle 5, adjusts the support rod 4 to the appropriate position, aligns the grinding disc 1 with the template area to be cleaned, turns on the 220V power supply, and the motor 2 starts to rotate. The fixed head drives the grinding disc 1 to rotate. The operator adjusts the grinding angle and height using the pin 3 according to the surface condition of the template, ensuring that the grinding disc 1 thoroughly cleans the template surface. During the grinding process, the dust removal device 6 starts simultaneously to collect the dust generated during cleaning. The vacuum cleaner 61 is powered through an external wire, generating suction. The suction generated by the vacuum cleaner 61 is first transmitted to the dust bin 63 through the connecting pipe 62. The dust bin 63 temporarily stores the dust. Then, the suction from the dust bin 63 is transmitted to the mounting housing 65 through the suction pipe 64. A dispersion net 66 is fixed inside the mounting housing 65. After the suction reaches the mounting housing 65... The dispersing net 66 evenly distributes the suction force, ensuring a relatively uniform dust collection effect around the grinding disc 1. Four conveying pipes 67 are fixed to the bottom of the mounting shell 65. After being evenly distributed by the dispersing net 66, the suction force is transmitted vertically downwards through these four conveying pipes 67. The conveying pipes 67 transmit the suction force to the dust collection ring 68, and the connecting groove 683 transmits the suction force to the dust collection pipe 682. The dust collection pipe 682 plays a role in evenly distributing the suction force. When the grinding disc 1 generates dust during operation, the dust collection hole 684 sucks the dust in under the action of suction. The dust passes sequentially through the dust collection hole 684, the dust collection pipe 682, the connecting groove 683, the conveying pipe 67, the mounting shell 65, and the dust collection pipe 64, finally entering the dust bin 63 for collection. This effectively collects the dust generated during the template cleaning process, allowing operators to clearly see the template surface and the surrounding environment, ensuring the accuracy and efficiency of the operation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
