[0001] The utility model relates to the technical field of PE pipe hot melting, in particular to a hot melting device for connecting PE pipes. Background Art
[0002] PE pipes are made of polyethylene materials, containing only two elements of carbon and hydrogen, with good sanitary performance. When connecting two sections of PE pipes, a hot melting machine is used to perform hot melting connection to make the connection more firm.
[0003] Currently, when the existing hot melting machine is in use, the heating plate and die head set on the machine body will deeply heat the pipe fittings. After the hot melting connection is completed, the temperature of the heating plate and die head is still relatively high. Since the heating plate and die head are directly exposed, in order to prevent the hot melting machine from accidentally injuring staff or other tools during transportation, it is necessary for the staff to let the hot melting machine stand still for a long time before transportation, which will affect the work efficiency of the staff. Therefore, we propose a hot melting device for connecting PE pipes to solve the above problems. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a hot melting device for connecting PE pipes.

Two groups of vertical plates are distributed at the top end of the hot melting machine base, and a rotating shaft is connected between the two groups of vertical plates through bearings. A rotating block is sleeved outside the rotating shaft, and a protective cover is connected to the outside of the rotating block.
[0007] In this device, through the setting of the protective cover and the rotating block, after use, through the setting of the protective cover, the heating plate with a relatively high temperature can be covered and protected, so that it is convenient for the staff to quickly transport this device, without consuming a long time waiting for the heating plate to cool, and the work efficiency of the staff can be effectively improved.
[0008] Preferably, a connecting block is connected to the side of the protective cover, and the connecting block is set as a frame structure.
[0009] Preferably, heat dissipation grooves are formed inside the protective cover, and the heat dissipation grooves are evenly distributed at the front and rear ends of the protective cover.
[0010] Preferably, the bottom ends of the two groups of vertical plates are connected through a mounting plate, and the inside of the mounting plate is connected to the hot melting machine base through bolts.
[0011] Preferably, moving blocks are respectively arranged on one side of the vertical plates close to each other, and the moving blocks are arranged in a U-shaped structure. The bottoms of the two groups of moving blocks are connected by a connecting strip.

[0013] Preferably, connecting springs are vertically connected to the inner walls of the sliding grooves, and the other ends of the connecting springs are connected to the sliding block plates.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0023] Referring to Figures 1-4 , a hot-melt device for connecting PE pipes includes a hot-melt machine base 1. A heating plate 2 is provided above the hot-melt machine base 1. A die head is connected to the side wall of the heating plate 2. The welding principle of the hot-melt machine base 1 and the heating plate 2 for PE pipes is prior art and will not be elaborated here. Two groups of vertical plates 3 are distributed at the top end of the hot-melt machine base 1. A rotating shaft 4 is connected between the two groups of vertical plates 3 through bearings. A rotating block 5 is sleeved outside the rotating shaft 4. A protective cover 6 is connected to the outside of the rotating block 5. The rotating block 5 and the rotating shaft 4 are fixedly connected. Therefore, when the protective cover 6 rotates, the rotating shaft 4 and the rotating block 5 can be driven to rotate simultaneously.
[0024] Furthermore, referring to Figure 1 and Figure 2 , it can be known that a connecting block 8 is connected to the side of the protective cover 6, and the connecting block 8 is arranged in a frame structure. During use, through the connecting block 8 arranged in a frame structure, it is convenient for the staff to rotate the protective cover 6.
[0025] Furthermore, referring to Figure 2 and Figure 3 , it can be known that heat dissipation grooves 7 are opened inside the protective cover 6, and the heat dissipation grooves 7 are evenly distributed at the front and rear ends of the protective cover 6. During use, through the opening of multiple groups of heat dissipation grooves 7, the heat on the heating plate 2 can be normally dissipated.
[0026] Furthermore, referring to Figure 3 , it can be known that the bottom ends of the two groups of vertical plates 3 are connected by a mounting plate 9, and the inside of the mounting plate 9 is connected to the hot-melt machine base 1 through bolts. Through the mutual cooperation of the mounting plate 9 and the bolts, the connection operation of the two groups of vertical plates 3 and the hot-melt machine base 1 can be realized. During the maintenance process, it is convenient to disassemble the two groups of vertical plates 3 together with the protective cover 6, so as to facilitate the staff to repair the hot-melt machine base 1 and the heating plate 2.
[0027] Furthermore, referring to Figure 3 and Figure 4 , it can be known that moving blocks 10 are respectively provided on the sides of the vertical plates 3 close to each other, and the moving blocks 10 are arranged in a U-shaped structure. The bottom ends of the two groups of moving blocks 10 are connected by a connecting strip 12. An inlay block 11 is connected to the inside of the moving block 10. Symmetrically arranged card slots adapted to the inlay block 11 are opened inside the rotating shaft 4. Since two groups of card slots are symmetrically opened inside the rotating shaft 4 and are matched with the setting of the inlay block 11, it is convenient for the staff to limit the rotating shaft 4 rotated by 180 degrees.
[0028] Further, referring to Figure 4 it can be known that slider plates 13 are respectively connected to the sides of the connecting bar 12, and sliding grooves 14 adapted to the slider plates 13 are formed inside the vertical plates 3. Through the mutual cooperation of the slider plates 13 and the sliding grooves 14, the stable up and down movement of the moving blocks 10 and the inserting blocks 11 can be ensured, and it is convenient for the staff to pull the slider plates 13 from the outside and drive the simultaneous movement of the two groups of moving blocks 10, thereby improving the convenience during the use of the device.
[0029] Further, referring to Figure 4 it can be known that connecting springs 15 are vertically connected to the inner walls of the sliding grooves 14, and the other ends of the connecting springs 15 are connected to the slider plates 13. Through the connecting springs 15 connected to the slider plates 13, the tightness of the inserting blocks 11 clamped inside the rotating shafts 4 can be improved, and when the staff stops pulling the slider plates 13, the moving blocks 10 can automatically reset through the elastic force of the connecting springs 15, thereby further improving the convenience during the use of the device.
[0030] Working principle: When the present utility model is in use, the staff can first place the device in a suitable area, and then pull the slider plates 13 upward, so that the connecting bar 12 and the moving blocks 10 are simultaneously stressed and move upward. At this time, the inserting blocks 11 are withdrawn from the inside of the rotating shafts 4 to release the limit on the rotating shafts 4. Then the staff can pull the connecting blocks 8 to drive the protective cover 6 to rotate 180 degrees. At this time, the staff can stop pulling the slider plates 13, so that the moving blocks 10 and the inserting blocks 11 are clamped into the other set of card slots of the rotating shafts 4 through the elastic force of the connecting springs 15. At this time, the heating plates 2 and the dies arranged on their sides are exposed. At this time, the staff can turn on the hot melt machine base 1 to heat the heating plates 2 and the dies. Then the staff can insert the pipes to be welded into the dies for heating to complete the connection operation between the PE pipes. After the welding is completed, the staff can pull down the slider plates 13 again and rotate the connecting blocks 8 to drive the protective cover 6 to cover the heating plates 2 and the dies again, so as to facilitate the staff to transport the device. The above is the entire working principle of the present utility model.
