Problems solved by technology

In addition, in the current grinding process, the coating cylinder is filled directly into the mold manually. Because the coating cylinder has a certain processing tolerance and the size of the mold is fixed, sometimes it is difficult to load the coating cylinder into the mold, and sometimes the coating cylinder is loaded into the mold. The back of the mold is too loose, the contact force is not enough, and the coating cylinder will rotate relative to the mold during the grinding process
[0003] At present, the grinding device for the inner wall of the polyurethane coating cylinder mainly has the following problems: (1) The effect of manual grinding of the coating layer has a great relationship with the experience and physical strength of the operator, resulting in poor product quality consistency; (2) The grinding process personnel have a high labor intensity , resulting in low production efficiency per unit time; (3) The size of the grinding force is uncontrollable, and the filling of the coating cylinder is too tight or too loose; (4) When manually grinding the coating layer, people and high-speed rotating machines operate face to face, There are many potential risk factors such as dust inhalation, solvent erosion, mechanical torsion and collision

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 1 and figure 2 As shown in the figure, a self-adaptive grinding device for the inner wall of a polyurethane-coated cylinder includes an automatic loading and unloading mechanism 1, an automatic clamping mechanism 2, an automatic grinding mechanism 3, a dust recovery system 4, and a closed casing 5, wherein the automatic clamping mechanism 2 , The automatic grinding mechanism 3 is sealed inside the closed casing 5 .

[0018] Such as image 3 As shown, the automatic loading and unloading mechanism 1 includes a silo 11, a feeding port 12, a pneumatic expansion shaft 13, and a two-dimensional guide rail 14. The silo 11 is installed obliquely. Under the action of gravity, it slides along the wall surface of the feed bin 11 to the feeding port 12, and the feeding port 12 is opened at the bottom of the feeding bin 11. In the...

Abstract

The invention discloses a self-adaptation polyurethane wrapping barrel inner wall face grinding device. The problems that a traditional grinding device is high in personnel labor intensity, low in grinding efficiency, poor in process safety, poor in product size deviation adaptability and the like. The self-adaptation polyurethane wrapping barrel inner wall face grinding device comprises an automatic feeding and discharging mechanism (1), an automatic clamping mechanism (2), an automatic grinding mechanism (3), a dust recycling system (4) and a closed shell (5). The automatic clamping mechanism (2) and the automatic grinding mechanism (3) are closed in the closed shell (5). The automatic feeding and discharging mechanism (1) comprises a material bin (11), a material taking port (12), a pneumatic expansion shaft (13) and a two-dimension guide rail (14), and the material bin (11) is obliquely arranged. By means of the self-adaptation polyurethane wrapping barrel inner wall face grindingdevice, grinding of the inner wall faces of multiple types and specifications of rotation body wrapping barrels can be achieved, the grinding efficiency is improved, the process danger is reduced, andadaptability of the equipment to the product size deviation is improved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, mainly to the field of automation equipment, and in particular to a self-adaptive grinding device for the inner wall of a polyurethane-coated cylinder. Background technique [0002] The polyurethane coated cylinder is a flexible thin-walled cylinder with an arc-shaped closed head at one end. When the coating cylinder is in use, its inner wall surface needs to be polished to form a rough surface, which is conducive to the firmness of the bonding. The traditional cladding cylinder is polished by hand-held wooden sticks, and scotch tape is used to entangle sandpaper on the top of the wooden sticks for grinding. In addition, in the current grinding process, the coating cylinder is filled directly into the mold manually. Because the coating cylinder has a certain processing tolerance and the size of the mold is fixed, sometimes it is difficult to load the coating cylinder into the mold, and someti...
