Description

Technical Field

[0001] The utility model relates to the technical field of hot melt machine component installation, in particular to a hot melt machine gasket installation and fixing structure. Background Art

[0002] The hot melt machine is an instrument that uses electric heating to transfer the heat of the heating plate to the welding surface of the upper and lower plastic heating parts to melt the surface, and then quickly withdraw the heating plate to fuse, solidify and integrate the upper and lower heating parts after heating the molten surfaces. The whole machine is in the form of a frame, consisting of three plates: the upper template, the lower template, and the hot template, and is equipped with a hot mold, upper and lower plastic cold molds, and the action mode is pneumatic control and manual. It is mainly suitable for welding plastic parts such as household appliances, car lights, and automobile containers. The gasket is made of paper, rubber or copper sheets, and is placed between two planes to strengthen the sealing material. To prevent fluid leakage, the sealing element set between the static sealing surfaces cannot be perfect due to the imperfect machined surface, and the use of gaskets can fill the irregularities.

[0003] However, when using gaskets on the hot melt machine, since the hot melt machine is prone to vibration during startup and will affect the stability of the gasket during transfer, the gasket is prone to fall off. Therefore, the gasket needs to be fixed without affecting the operation of the hot melt machine. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 , Figure 2 As shown, a gasket installation and fixing structure on a hot melt machine includes a hollow plate 1, a clamping block 2 is fixedly connected to the right side of the inner wall of the hollow plate 1, a semicircular groove is opened on the top surface of the clamping block 2, two groups of connecting components 4 are fixedly connected to both sides of the hollow plate 1, a fixing component 3 is fixedly connected to the left side of the inner wall of the hollow plate 1, and the right end of the fixing component 3 is fixedly connected to the left end of the clamping block 2.

[0025] like Figure 3 , Figure 4As shown, the fixing assembly 3 includes a fixing plate 31, the left side of the fixing plate 31 is fixedly connected to the left side of the inner wall of the hollow plate 1, the right end of the fixing plate 31 is fixedly connected to the left side of the clamping block 2, two groups of movable grooves 39 are opened inside the two sides of the fixing plate 31, and the top surface of the fixing plate 31 is threadedly connected with two groups of screws 32, and the two groups of screws 32 enter the two groups of movable grooves 39 respectively.

[0026] Furthermore, two groups of slide grooves 36 are formed on the inner bottom surfaces of the two movable grooves 39 , and the inner walls of the two slide grooves 36 are slidably connected with sliders 34 .

[0027] A slider 34 and a slide groove 36 are provided, and the slider 34 slides in the slide groove 36 to drive the connecting rod 35 to move horizontally.

[0028] like Figure 3 , Figure 4 As shown, the opposite surfaces of the two sliders 34 are fixedly connected with a connecting rod 35, and the right end of the connecting rod 35 is fixedly connected with an arc plate 33, and the radius of the arc plate 33 is consistent with the radius of the semicircular notch.

[0029] The arc plate 33 is displaced by the connecting rod 35, and the radius consistent with the semicircular notch allows the arc plate 33 to cooperate with the clamping block 2 to effectively clamp and fix the gasket placed therein, and the clamping method can also make it more convenient to replace the gasket when it is worn.

[0030] like Figure 3 , Figure 4 As shown, the bottom ends of the two screw rods 32 are rotatably connected to the racks 37 , and the top surfaces of the two sliders 34 are fixedly connected to multiple groups of limiting teeth 38 distributed in a linear array, and the surfaces of the limiting teeth 38 are meshed with the surfaces of the racks 37 .

[0031] The limiting teeth 38 and the rack 37 are provided to limit the position of the slider 34 by means of bite fixing. After the arc plate 33 fixes the gasket, the slider 34 can no longer move at will, thereby ensuring the stability of the gasket.

[0032] like Figure 5 As shown, the two connecting components 4 each include a connecting plate 41, the side of the connecting plate 41 is fixedly connected to the side of the hollow plate 1, a movable groove 42 is opened at the midline of the bottom surface of the connecting plate 41, the front of the connecting plate 41 is rotatably connected to a screw block 47, the inner wall of the movable groove 42 is rotatably connected to a bidirectional screw 43 and one end of the bidirectional screw 43 is fixedly connected to the end of the screw block 47, and the inner wall of the movable groove 42 is fixedly connected to two sets of limit rods 44.

[0033] Furthermore, two groups of moving blocks 45 are slidably connected to the outer surfaces of the two limiting rods 44 , and the interiors of the two groups of moving blocks 45 are threadedly connected to the outer surface of the bidirectional screw 43 , and the top surfaces of the two moving blocks 45 are fixedly connected to the clamping blocks 46 .

[0034] A bidirectional screw rod 43 and a limiting rod 44 are provided. When the bidirectional screw rod 43 rotates, two groups of moving blocks 45 on the surface thereof move horizontally along the direction of rotation and the limiting rod 44 .

[0035] like Figure 5 As shown, the surface threads of the bidirectional screw 43 are divided into forward and reverse threads on both sides with the midpoint as the boundary, and the two moving blocks 45 are symmetrical about the midline of the bidirectional screw 43.

[0036] When the bidirectional screw 43 rotates, the two groups of symmetrical moving blocks 45 will synchronously move toward the midpoint of the bidirectional screw 43 through the forward and reverse threads on the surfaces thereof.

[0037] The working principle of the utility model is as follows: the gasket is placed in the card block 2, and then the screw block 47 is rotated to make the bidirectional screw 43 rotate in the moving groove 42, so that the two groups of moving blocks 45 on its surface follow the direction of rotation and the positive direction thread, and under the limit of the limit rod 44, complete the synchronous and uniform horizontal displacement, so that the two groups of clamping blocks 46 are synchronously displaced toward the center, so as to fix the hollow plate 1 on the hot melt machine, and then the screw 32 is rotated to make it move upward on the fixed plate 31. At this time, the bottom end of the screw 32 rotates on the rack 37, and the rack 37 also moves with the upward movement of the screw 32, so that the rack 37 is disengaged from the limiting tooth 38 and no longer restricted, and then with the help of the two groups of sliders 34, the connecting rod 35 is pushed to make the arc plate 33 cooperate with the card block 2 to fix and clamp the inserted gasket, and after clamping, the screw 32 is twisted downward to make the rack 37 engage with the limiting tooth 38, thereby deepening the stability of the gasket.

[0038] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
