Description

Technical Field

[0001] This invention relates to the field of pipe processing equipment, and more specifically to a portable plastic pipe surface thickener. Background Technology

[0002] Reverse osmosis (RO) technology has been widely used in industrial wastewater treatment and domestic drinking water production. The RO membrane center tube is an indispensable component of RO technology. Due to market demands, the outer diameters at both ends of the center tube of a certain type of RO filter cartridge need to be roughened with sandpaper to increase its surface roughness. Currently, this is done manually, which suffers from low efficiency, poor product appearance consistency, and high processing costs. To address this issue, a portable plastic tube surface roughening device is designed to solve the technical problems associated with current manual processing. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a portable plastic tube surface thickener that improves product appearance consistency, increases production efficiency, and reduces production costs, thereby addressing the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: a portable plastic tube surface thickener, comprising a shell body, a motor, and sandpaper. One end of the shell body has an opening, and the opposite end has an end cap. The end cap has an opening and a power switch. An annular protrusion is provided on the inner wall of the shell body near the opening. The annular protrusion and the inner wall of the shell body are respectively provided with an upper conical surface and a lower conical surface. The motor is installed inside the shell body, and an elastic element is installed between the motor and the end cap. A trigger-type timer switch is provided on the top of the motor. The motor's drive shaft is connected to an adapter plate, and the adapter plate is detachably connected to a sandpaper mounting bracket. The sandpaper is mounted on the sandpaper mounting bracket. The end of the sandpaper mounting bracket has a bent portion, and the bent portion has a back conical surface corresponding to the lower conical surface.

[0005] Preferably, the opening is located at the center of the end cap.

[0006] Preferably, the rear end of the back cone surface is provided with a sandpaper clamping block.

[0007] Preferably, the sandpaper is fixedly mounted on the sandpaper mounting bracket by a pressure block and a locking screw.

[0008] Preferably, the adapter plate is connected to the sandpaper mounting bracket via connecting screws.

[0009] Preferably, the elastic element is a spring.

[0010] Preferably, the outer casing body is also provided with an observation port.

[0011] Preferably, the outer shell body is a hollow cylinder.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention combines machine and manual labor to grind both ends of the central tube to increase its surface roughness. Specifically, by turning on the power switch, the portable plastic tube surface thickener of this invention is placed on the central tube to be processed. When one end of the central tube contacts the adapter plate, under the action of the operator's external force, the outer shell first uses its lower conical surface to push the sandpaper mounting bracket, making the sandpaper contact the surface to be processed on the central tube. Next, the outer shell presses the trigger-type timer switch, the motor is powered on, and the sandpaper on the sandpaper mounting bracket rotates on the outer circumference of the central tube to be processed through the adapter plate until the time set by the trigger-type timer switch is reached and then the rotation stops. At this time, one central tube is processed. The operator removes the external force, and the outer shell first releases the trigger-type timer switch under the action of the spring, and then removes the external force applied to the sandpaper mounting bracket through the lower conical surface. Then the portable plastic tube surface thickener can be removed, and the entire processing operation is completed. In summary, the processing of this invention can improve the consistency of product appearance, increase production efficiency, and reduce production costs. Attached Figure Description

[0016] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] like Figures 1 to 3As shown, this invention discloses a portable plastic tube surface thickener, comprising a housing body 1, a motor 2, and sandpaper 3. Specifically, the housing body 1 is a hollow cylinder with an opening 11 at one end and an end cap 12 at the opposite end. The end cap 12 has an opening 13 and a power switch 14, with the opening 13 located at the center of the end cap 12. The power switch 14 is electrically connected to the motor 2, controlling the connection between the motor 2 and the power source. An annular protrusion 15 is located on the inner wall of the housing body 1 near the opening 11. The annular protrusion 15 and the inner wall of the housing body 1 are respectively provided with an upper conical surface 16 and a lower conical surface 17. The motor 2 is installed inside the housing body 1, and the motor 2 is connected to the end cap... An elastic element 4 is installed between 12. The elastic element 4 of this invention is a spring. Of course, other elastic elements can be selected as needed. A trigger-type timer switch 5 is provided on the top of the motor 2. The trigger-type timer switch 5 of this invention is an existing device. For simplicity, its structure and working principle will not be described in detail. The transmission shaft of the motor 2 is connected to the adapter plate 6. The adapter plate 6 is connected to the sandpaper mounting bracket 7 in a detachable manner. Specifically, the sandpaper 3 is fixedly installed on the sandpaper mounting bracket 7 by the pressure block 74 and the locking screw 75. The sandpaper 3 is installed on the sandpaper mounting bracket 7. The end of the sandpaper mounting bracket 7 is provided with a bending part 71. The bending part 71 is provided with a back cone surface 72 corresponding to the lower cone surface 17.

[0018] In order to better contact the sandpaper 3 on the sandpaper mounting bracket 7 with the surface of the center tube to be processed, so as to better meet the requirements of thickening, a sandpaper clamping block 73 is provided at the rear end of the back cone surface 72. During the downward pressing of the outer shell body 1, the lower cone surface 17 is continuously squeezed with the sandpaper clamping block 73, so that the sandpaper 3 on the sandpaper mounting bracket 7 can better contact the center tube to be processed.

[0019] To facilitate observation of the interior of the outer casing 1, an observation port 18 is also provided on the outer casing 1.

[0020] The specific operation of this invention is as follows: Turn on the power switch 14, and place the outer casing 1 onto the center tube to be processed. When one end of the center tube contacts the adapter plate 6, under the action of the operator's external force, by pressing the outer casing 1, the outer casing 1 first uses its lower conical surface 17 to push against the sandpaper mounting bracket 7 containing sandpaper 3, causing the sandpaper 3 to contact the surface to be processed on the center tube. Next, the outer casing 1 presses the trigger-type timer switch 5, energizing the motor 2. Through the adapter plate 6, the sandpaper 3 on the sandpaper mounting bracket 7 rotates at the outer circumference of the center tube to be processed until the time set by the trigger-type timer switch 5 is reached, at which point the rotation stops. At this point, one center tube is processed. The operator removes the external force, and the outer casing 1, under the action of the spring, first releases the trigger-type timer switch 5, then removes the external force applied to the sandpaper mounting bracket 7 through the lower conical surface 17. Then, the outer casing 1 can be removed, and the entire processing operation is completed. Compared with existing manual polishing methods, the portable plastic tube surface thickener of the present invention uses sandpaper 3 to polish the outer wall of the central tube to be processed, thereby achieving the thickening operation. The present invention has better polishing consistency and the overall work efficiency is also greatly improved, reducing the production and processing cost.
