Description

Technical Field

[0001] The utility model belongs to the technical field of electric heating ring installation, and specifically relates to a novel electric heating ring installation structure. Background Art

[0002] The heating coil is also called electric heating coil or heating coil. It uses electric heating alloy wire as heating material and mica soft board (sometimes ceramic core) as insulation material. It can be used on the extrusion tube of the injection molding machine to heat and keep the extruded material warm to prevent solidification.

[0003] Most of the installation structures of the electric heating coils in the prior art are simply sleeved on the outer circumference of the extrusion tube of the injection molding machine, and lack a corresponding structure to limit the aperture size of the electric heating coil, so that the electric heating coil is prone to slipping, thereby affecting its modification of heating and heat preservation of the extruded material to prevent solidification, resulting in certain limitations in its use.

[0004] Therefore, a new type of electric heating coil installation structure is needed to solve the problem that most of the existing technologies are simply sleeved on the outer peripheral surface of the extrusion tube of the injection molding machine, lacking a corresponding structure to limit the aperture size of the electric heating coil, which makes it easy for the electric heating coil to slip.

[0007] A novel electric heating coil installation structure comprises an electric heating coil shell, an inner hot end is arranged inside the electric heating coil shell, two connecting blocks are fixed to the surface of one end of the electric heating coil shell, a slot with a T-shaped cross section is opened on the surface of the connecting block, a connecting groove is connected on one side of the slot, a plug with a T-shaped cross section is inserted inside the slot, an inner groove is opened on the surface of the plug close to each other, a movable plate is inserted inside the inner groove, a threaded rod is threadedly connected to the surface of the top of the plug, one side of the threaded rod is rotatably connected to the surface of the movable plate at an adjacent position, a resistance groove is connected to the bottom of the inner cavity of the inner groove, a resistance strip is inserted inside the resistance groove, the top of the resistance strip passes through the resistance groove at the adjacent position and is fixed to the surface of the bottom of the movable plate, one end of the plug passes through the connecting groove at the adjacent position and extends out of the connecting groove, and a connecting plate is fixed to the surface of one end of the two plugs extending out of the connecting groove.

[0008] It should be noted in the scheme that a rubber block is fixed to the surface of the other end of the electric heating coil shell, arc-shaped ring plates are arranged on both sides of the rubber block and the connecting plate, and positioning grooves are provided on the surfaces on both sides of the connecting plate and the surfaces on both sides of the rubber block.

[0009] It is further worth noting that an insert block is slidably inserted inside the positioning groove, and the surface of the insert block close to the adjacent position ring plate passes through the positioning groove and is fixed to the surface of the adjacent position ring plate.

[0010] It should be further explained that movable rods are evenly inserted through the surface of the ring plate, and a resistance plate is fixed to the surface of the movable rod close to the electric heating coil shell. The surface of the resistance plate close to the electric heating coil shell is arranged in an arc shape, and the surface of the resistance plate close to the electric heating coil shell is in contact with the outer peripheral surface of the electric heating coil shell.

[0015] (2) By arranging rubber blocks on both sides of the outer circumference of the electric heating coil shell and using the spring's rebound force to make the contact plate tightly adhere to the outer circumference of the electric heating coil shell, the electric heating coil shell can tightly grasp the outer circumference of the extruded tube to increase the friction between it and the extruded tube, thereby further preventing the electric heating coil shell from sliding, thereby further improving the stability during use.

[0024] See also Figure 1-6 The utility model provides a novel electric heating coil installation structure, including an electric heating coil shell 1, an inner hot end 2 is arranged inside the electric heating coil shell 1, two connecting blocks 3 are fixed on the surface of one end of the electric heating coil shell 1, a slot 4 with a T-shaped cross section is provided on the surface of the connecting block 3, a connecting groove 5 is connected to one side of the slot 4, a plug 6 with a T-shaped cross section is inserted inside the slot 4, an inner groove 8 is provided on the surface of the plug 6 on the side close to each other, a movable plate 9 is inserted inside the inner groove 8, a threaded rod 10 is threadedly connected to the surface of the top of the plug 6, one side of the threaded rod 10 is rotatably connected to the surface of the movable plate 9 at the adjacent position, a resistance groove 11 is connected to the bottom of the inner cavity of the inner groove 8, a resistance strip 12 is inserted inside the resistance groove 11, the top of the resistance strip 12 passes through the resistance groove 11 at the adjacent position and is fixed to the surface of the bottom of the movable plate 9, one end of the plug 6 passes through the connecting groove 5 at the adjacent position and extends out of the connecting groove 5, and a connecting plate 7 is fixed to the surface of one end of the two plugs 6 extending out of the connecting groove 5.

[0025] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth explaining in detail that a rubber block 13 is fixed to the surface of the other end of the electric heating coil housing 1, and arc-shaped ring plates 14 are arranged on both sides of the rubber block 13 and the connecting plate 7. Positioning grooves 15 are provided on the surfaces on both sides of the connecting plate 7 and the surfaces on both sides of the rubber block 13. Insertion blocks 16 are slidably inserted into the interior of the positioning grooves 15. The surface of the insertion block 16 on the side close to the adjacent ring plate 14 passes through the positioning groove 15 and is fixed to the surface of the adjacent ring plate 14. By inserting the insertion block 16 into the interior of the positioning groove 15 from the top of the positioning groove 15, the ring plate 14 can be installed at the positions on both sides of the electric heating coil housing 1.

[0026] Further as Figure 3 As shown, it is worth specifically explaining that a movable rod 17 is uniformly inserted through the surface of the ring plate 14, and a contact plate 18 is fixed to the surface of the movable rod 17 close to the electric heating coil housing 1. The surface of the contact plate 18 close to the electric heating coil housing 1 is arranged in an arc shape, and the surface of the contact plate 18 close to the electric heating coil housing 1 is in contact with the outer peripheral surface of the electric heating coil housing 1. A fixed disk 19 is fixed to the surface of the movable rod 17 away from the electric heating coil housing 1. A spring 20 is sleeved on the outer peripheral surface of the movable rod 17, and one side of the spring 20 is in contact with the surface of the ring plate 14 at the adjacent position. The other side of the spring 20 is fixed to the surface of the adjacent fixed disk 19. When the ring plate 14 is installed to the positions on both sides of the electric heating coil shell 1, the outer circumference of the electric heating coil shell 1 will contact the contact plate 18, so that the movable rod 17 extends away from the electric heating coil shell 1, so that the fixed disk 19 can stretch the adjacent spring 20 to deform it, so that the contact plate 18 can be tightly attached to the outer circumference of the electric heating coil shell 1 under the action of the rebound force of the spring 20, so that the electric heating coil shell 1 can tightly buckle the outer circumference of the extruded tube.

[0027] This scheme has the following working process: in the actual use process, when the user needs to install the electric heating coil shell 1, firstly, through the deformable characteristics of the electric heating coil shell 1 itself, the electric heating coil shell 1 can be sleeved on the outer peripheral surface of the extruded tube from the notch at one end of the electric heating coil shell 1, so that the inner hot end 2 can fit the outer peripheral surface of the extruded tube to play a role in heating and heat preservation to prevent solidification, and then the two insertion strips 6 at one end of the connecting plate 7 are inserted from the top of the slot 4, and then the threaded rod 10 is rotated. Since the interference groove 11 can interfere with the interference strip 12 at the adjacent position, the interference strip 12 and the movable plate 9 can only move in the horizontal direction, so that the movable plate 9 and the interference strip 12 can move in the horizontal direction under the cooperation of the threaded structure between the threaded rod 10 and the insertion strip 6, thereby extending to the inside of the adjacent connecting groove 5, so as to fix the slot 4, so as to be able to move between the slot 4 and the insertion strip 6 Under the resistance of and the connection of the connecting plate 7, the aperture of the electric heating coil housing 1 can be prevented from expanding and causing the electric heating coil housing 1 to slip off the extruded tube. Subsequently, the insert block 16 is inserted into the interior of the positioning groove 15 from the top of the positioning groove 15, so that the ring plate 14 can be installed at the positions on both sides of the electric heating coil housing 1. When the ring plate 14 is installed to the positions on both sides of the electric heating coil housing 1, the outer circumference of the electric heating coil housing 1 will resist the resistance plate 18, so that the movable rod 17 extends in the direction away from the electric heating coil housing 1, so that the fixed disk 19 can stretch the adjacent position spring 20 to deform it, so that the resistance plate 18 can be tightly attached to the outer circumference of the electric heating coil housing 1 under the action of the rebound force of the spring 20, so that the electric heating coil housing 1 can tightly buckle the outer circumference of the extruded tube, thereby further ensuring that the electric heating coil housing 1 and the inner hot end 2 can be tightly attached to the outer circumference of the extruded tube.

[0028] According to the above working process, it can be known that: by inserting the two insertion strips 6 at one end of the connecting plate 7 into the interior of the slot 4, and then rotating the threaded rod 10 so that the movable plate 9 and the interference strip 12 can extend to the interior of the adjacent insertion strip 6, so that the interference between the insertion strip 6 and the slot 4 can limit the aperture size of the electric heating coil housing 1 sleeved on the outer periphery of the extruded tube, thereby avoiding the expansion of the electric heating coil housing 1 and causing the electric heating coil housing 1 to slip, thereby improving the stability of the device when in use. By arranging rubber blocks 13 on both sides of the outer peripheral surface of the electric heating coil housing 1, and through the rebound force of the spring 20, the interference plate 18 is tightly attached to the outer peripheral surface of the electric heating coil housing 1, so that the electric heating coil housing 1 can tightly buckle the outer peripheral surface of the extruded tube to expand the friction between it and the extruded tube, thereby further avoiding the electric heating coil housing 1 from sliding, thereby further improving the stability when in use.

[0029] Further as Figure 2As shown, it is worth explaining in detail that the cross-section of the inner cavity of the positioning groove 15 is T-shaped, and the cross-section of the plug block 16 is T-shaped. Due to the shape of the positioning groove 15 and the plug block 16, the ring plate 14 can be prevented from horizontally shaking from the positions on both sides of the connecting plate 7 and the rubber block 13 under the interference of the positioning groove 15 and the plug block 16, thereby further improving the limiting effect.

[0030] In summary, by inserting the two insertion strips 6 at one end of the connecting plate 7 into the interior of the slot 4, and then rotating the threaded rod 10 so that the movable plate 9 and the interference strip 12 can extend to the interior of the adjacent insertion strip 6, so that the size of the aperture of the electric heating coil housing 1 sleeved on the outer periphery of the extruded tube can be limited under the interference between the insertion strip 6 and the slot 4, thereby preventing the electric heating coil housing 1 from sliding due to its expansion, thereby improving the stability of the device when in use. By arranging the rubber blocks 13 on both sides of the outer periphery of the electric heating coil housing 1, and by the return of the spring 20 The elastic force makes the contact plate 18 close to the outer circumference of the electric heating coil housing 1, so that the electric heating coil housing 1 can tightly buckle the outer circumference of the extruded tube to increase the friction between it and the extruded tube, thereby further avoiding the electric heating coil housing 1 from sliding, thereby further improving the stability during use. Due to the shape setting of the positioning groove 15 and the plug block 16, the ring plate 14 can be prevented from horizontally shaking from the positions on both sides of the connecting plate 7 and the rubber block 13 under the interference effect of the positioning groove 15 and the plug block 16, thereby further improving the limiting effect.
