DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-8 , the present invention provides a technical solution:

[0029] Embodiment 1: A ceramic lined pipe automatic powder feeding tool, comprising a symmetrically arranged long strip of left L-shaped sheet metal 1 and a right L-shaped sheet metal 2, the two long strips of left L-shaped sheet metal 1 and the right L-shaped sheet metal 2 are both set to be consistent with the length of the carbon steel pipe 100 to be coated, the left L-shaped sheet metal 1 and the right L-shaped sheet metal 2 can be selected from sheet metals similar to angle steel, the two L-shaped sheet metals are close to each other to form a structure shaped like a groove, and a flat end surface is formed at the bottom for loading powder, the left L-shaped sheet metal 1 and the right L-shaped sheet metal 2 are detachable, that is, the left L-shaped sheet metal 1 and the right L-shaped sheet metal 2 are in tight contact when they are close to each other to prevent the bottom from opening, and the left L-shaped sheet metal 1 and the right L-shaped sheet metal 2 are separated from each other at the connection, and the bottom The left and right L-shaped sheet metal parts 1 and 2 can be opened to realize the function of powder discharge, and the ends of the left and right L-shaped sheet metal parts 1 and 2 that are close to each other are fixedly connected with sealing gaskets 3, and the sealing gaskets 3 on both sides are in active contact with each other, so that the sealing gaskets 3 on both sides are sealed when they are in contact with each other. When the two sealing gaskets 3 are no longer in contact with each other and are separated from each other, the bottom end surface formed by the left L-shaped sheet metal part 1 and the right L-shaped sheet metal part 2 is opened and no longer sealed. A vise shaft 4 is arranged between the left and right L-shaped sheet metal parts 1 and 2, and the vise shaft 4 is arranged along the length direction of the left and right L-shaped sheet metal parts 1 and 2, and is in the opposite direction and parallel to the length of the left L-shaped sheet metal part 1, and the vise shaft 4 is not in contact and connected with the left and right L-shaped sheet metal parts 1 and 2, so as to facilitate the installation of the opening and closing vise structure.

[0030] An opening and closing vise mechanism is arranged on the vise shaft 4, and each set of opening and closing vise mechanisms includes a normally closed vise and an opening and closing vise which are rotatably connected to the vise shaft 4. The normally closed vise and the opening and closing vise are separately arranged on the vise shaft 4 and are arranged adjacent to each other. The normally closed vise includes a normally closed vise head 51 and a normally closed vise handle 52. The normally closed vise is a vise structure, and the two upper ends are normally closed vise heads 51, and the two lower ends are normally closed vise handles 52. The structure of the vise is cross-arranged, that is, the normally closed vise head 51 in the upper left corner is fixedly connected to the normally closed vise handle 52 in the lower right corner, and is rotatably connected to the vise shaft 4, that is, the normally closed vise head 51 and the normally closed vise handle 52 can rotate around the vise shaft 4. Similarly, the structure of the opening and closing vise is the same as that of the normally closed vise. The opening and closing vise includes an opening and closing vise head 61 and an opening and closing vise handle 62.

[0031] As the instruction manual Figure 2-4 As shown, a connecting spring 7 is fixedly connected between the two normally closed vise heads 51, and an electromagnet 8 is fixedly connected to one end of the two opening and closing vise heads 61 that are close to each other. A connecting spring 7 in a compressed state is fixedly connected between the two normally closed vise heads 51, and the two electromagnets 8 are energized to attract each other. Figure 2As shown, the connecting spring 7 is in a compressed state, and the connecting spring 7 provides a force to push the normally closed vise head 51 to the outer ends. However, at this time, the bottom is in a closed state because, as shown in the attached manual Figure 3 As shown, at this time, the electromagnet 8 is in the energized state, and the electromagnets 8 on both sides are attracted to each other, thereby pulling the opening and closing vise handle 62 inward, and driving the lower ends of the sheet metal parts on the left and right sides to be squeezed inward, so that the sealing gasket 3 at the bottom of the sheet metal parts is squeezed by the reaction force, so that the bottoms of the two L-shaped sheet metal parts are closed, forming a horizontal sealing groove body, so that the sealing gasket 3 at the bottom is closed, that is, when the adsorption force of the electromagnet 8 is greater than the elastic restoring force of the connecting spring 7 pushing outward, the opening and closing vise handle 62 will pull the sheet metal parts on the left and right sides inward, closing the bottom and preventing powder from being discharged. Later, if powdering is required, as shown in the attached manual Figure 4 As shown, the control electromagnet 8 is powered off, and then the electromagnet 8 loses its adsorption force. At this time, the restoring force of the connecting spring 7 has no external force to resist, and the connecting spring 7 will push the normally closed vise head 51 to the outer ends, thereby driving the normally closed vise handle 52 to push the sheet metal on the left or right side outward, so that the sealing gasket 3 at the bottom of the sheet metal is subjected to the reaction force and disengaged from each other, thereby opening the sealing gasket 3 at the bottom, and the effect of powder feeding and powder discharge can be achieved.

[0032] The two normally closed vise handles 52 are respectively connected to the left L-shaped sheet metal 1 and the right L-shaped sheet metal 2 through the connecting piece 9, and the two opening and closing vise handles 62 are respectively connected to the left L-shaped sheet metal 1 and the right L-shaped sheet metal 2 through the connecting piece 9. The setting of the connecting piece 9 can realize the connection between the vise handles and the sheet metal parts on the left and right sides, so as to better drive the left L-shaped sheet metal 1 and the right L-shaped sheet metal 2 to achieve the purpose of pulling inward or pushing outward through the vise handles, thereby controlling the opening and closing of the bottom.

[0033] Embodiment 2:

[0034] The difference from the first embodiment of the present application is that, as shown in the attached specification Figure 5-7 As shown, a connecting spring 7 is fixedly connected between the two normally closed vise heads 51, and an electromagnet 8 is fixedly connected to the ends of the two opening and closing vise heads 61 that are close to each other. A connecting spring 7 in an extended state is fixedly connected between the two normally closed vise heads 51, and the two electromagnets 8 repel each other when powered on. Figure 5 As shown, the connecting spring 7 is in an extended state, and the connecting spring 7 will provide a force to pull the normally closed vise head 51 inward, thereby pulling the normally closed vise handle 52 inward, and driving the lower ends of the sheet metal parts on the left and right sides to be squeezed inward, so that the sealing gasket 3 at the bottom of the sheet metal part is squeezed by the reaction force, so that the bottoms of the two L-shaped sheet metal parts are closed to form a horizontal sealing groove body, so that the sealing gasket 3 at the bottom is closed. At this time, as shown in the attached manual Figure 6As shown, at this time, the electromagnet 8 is in a power-off state and will not provide any external force to the opening and closing vise head 61 and the opening and closing vise handle 62, so it will not affect the closing effect of the connecting spring 7 in the extended state on the bottom sealing gasket 3, so that the bottom is always in a closed state at this time. Figure 7 As shown, the control electromagnet 8 is energized, and then the electromagnet 8 generates a mutually repulsive thrust, pushing the opening and closing vise head 61 outward, thereby driving the opening and closing vise handle 62 to push the sheet metal parts on both sides outward. At this time, when the repulsive thrust of the electromagnet 8 is greater than the elastic restoring force of the connecting spring 7 pulling inward, the opening and closing vise handle 62 will push the sheet metal parts on the left and right sides outward, thereby overcoming the spring force, so that the sealing gasket 3 at the bottom of the sheet metal part is subjected to a reaction force and disengaged from each other, thereby opening the sealing gasket 3 at the bottom, and the effect of powder feeding and powder discharge can be achieved.

[0035] As a most preferred embodiment, a plurality of opening and closing vise mechanisms are arranged on the vise shaft 4, and the plurality of opening and closing vise mechanisms are arranged at intervals on the vise shaft 4. Since the pipe is more than 4 meters long, many groups of the units can be placed, which can ensure the reliability of operation and the closing strength and opening strength.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
