[0034] Embodiment: According to the specification attached Figure 1-8It can be seen that this case is a split-type portable hot-melt butt welding machine, which mainly includes a base plate 1, a centering connection 2, a screw rod 3 and a pair of slides 4. The base plate 1 is a rectangular plate and a plurality of universal wheels 5 are installed on the bottom surface.

The lower bottom plate 1 is made of high-strength plastic material in one piece to reduce the weight of the structure and has a plurality of reinforcing ribs 38 at the bottom to strengthen the equipment. In order to improve the structural strength and supporting force, a pair of mutually parallel mounting plates 6 are respectively extended from both ends of the upper base plate 1. The upper base plate 1 and the lower base plate 1 are connected to each other by a plurality of tension bolts 33. The upper base plate 1 and the lower base plate 1 can be disassembled, so as to separate the lower base plate 1 with movable force from the upper base plate 1 for installation. On the one hand, it is convenient for transportation and handling. Secondly, the assembly is simple and the components therein can be effectively replaced, reducing the probability of damage to the whole machine. A pair of handles 34 are extended from both sides of the upper base plate 1 for carrying the whole machine. By driving the screw rod 3, the screw rod 3 is driven. The rod 3 is a coaxial reverse screw rod 3, and the two sides of the screw rod 3 below the centering connection 2 are external thread structures with opposite thread directions, and a pair of slides 4 are provided with internal thread holes matching the thread directions of the screw rod 3, so that when the screw rod 3 is engaged with the internal thread holes of the slide 4, the slide 4 is driven to move and the movement process of the slide 4 is stabilized by the slide rod 7, and when the screw rod 3 rotates, the thread movement directions of the slides 4 are opposite, so the slides 4 move in opposite directions, and the docking mechanism is pulled into the split hot-melt structure on the centering connection 2, completing hot-melt and docking;

[0035] The docking mechanism includes: a pair of split fixed structures and an action structure;

[0036] A pair of split fixed structures are installed on a pair of slides 4, and the action structure is installed on the bottom plate 1 and linked with the screw rod 3. During use, the screw rod 3 drives the slide 4 to move, pulls the pair of split fixed structures closer, clamps the two sides of a pair of plastic tubes through the split fixed structures, and then the action structure drives the screw rod 3;

[0037] According to the instruction manual Figure 1-8 It can be seen that the split fixing structure includes: a fixing block 8, two pairs of inserting blocks 9, a plurality of springs 28, balls 10, a semicircular groove plate 11, an upper buckle ring 12 and an adjusting knob 13, and the connection relationship and position relationship thereof are as follows;

[0038] Two pairs of plug-in slots are provided at the four corners of the slide 4, and two pairs of plug-in blocks 9 matching the plug-in slots are provided at the four corners of the lower wall of the fixed block 8. A plurality of springs 28 and balls 10 are provided on the two pairs of plug-in blocks 9, and the two pairs of plug-in slots matching therewith are provided with limit ring grooves matching the plurality of springs 28 and balls 10. A semicircular groove plate 11 is provided on the fixed block 8, and a lower semicircular groove is provided on the semicircular groove plate 11, and an upper buckle ring 12 is hinged on one side of the lower semicircular groove, and an upper semicircular groove is provided on the upper buckle ring 12, and a locking component is provided at one end of the semicircular groove plate 11, and a locking groove matching the locking component is provided on the upper buckle ring 12, and an adjusting knob 13 extends from the upper buckle ring 12;

[0039] In the specific implementation process, the plug block 9 on the fixed block 8 is inserted into the plug-in groove on the slide 4, and the spring 28 ball 10 is used for limiting. Due to the limiting effect of the spring 28 ball 10, the plug block 9 is double-limited in the longitudinal and horizontal directions to prevent the plug block 9 from moving and causing the fixed block 8 to fall off the slide 4. The outer wall of the pipe is fixed by the lower semicircular groove of the semicircular groove plate 11 and the upper semicircular groove of the upper buckle ring 12. The friction pad 36 is matched and installed on the inner wall surface of the lower semicircular groove and the upper semicircular groove to increase the fixing effect of the pipe. By adopting a hinged manner, the upper buckle ring 12 can make a circular motion on the semicircular groove plate 11 with a hinge. After the pipe is placed in the upper and lower semicircular grooves, the upper buckle ring 12 is moved to make the two buckle together to fix the pipe, and the locking groove is locked by adjusting the locking component, thereby increasing the buckling force, thereby increasing the friction force, and avoiding the pipe sliding during the hot melt butt joint process.

[0040] According to the instruction manual Figure 1-8 It can be seen that the split hot melt structure includes: a slot 14, a receiving plate 16, a socket 17, a plurality of clips 18, a flip plate 19, a hot melt head 20, a flip rod 21, a transformer 22 and a power switch 23, and the connection relationship and position relationship thereof are as follows;

[0041] A slot 14 is provided on one side of the centering connection 2, a socket 17 is provided on the receiving plate 16 to match the slot 14, a plurality of retaining springs 18 are provided on the inner ring of the slot 14, and a retaining groove matching the plurality of retaining springs 18 is provided on the matching socket 17, a flip plate 19 is hinged to one end of the receiving plate 16, a vertical plate 15 is vertically provided on the flip plate 19, a hot melt head 20 is installed on the vertical plate 15, a flip rod 21 is provided on the vertical plate 15, a transformer 22 is installed on the flip rod 21, and a power switch 23 is provided on the flip rod 21;

[0042] In the specific implementation process, the socket 17 is inserted into the slot 14, and the retaining spring 18 is used to engage the slot to limit and fix the socket 17, thereby fixing the receiving plate 16. When the pipes are respectively placed in the split fixing structures on both sides, the action structure is started to drive a pair of slides 4 to move toward each other, thereby pulling the pipes on both sides closer to insert them into the hot melt head 20, and the power supply switch 23 is started. The transformer 22 is powered by an external power supply. The transformer 22 converts the frequency and voltage to power the hot melt head 20, and the hot melt head 20 generates heat to generate a temperature of about 250-300°C, thereby hot-melting the pipe openings on both sides of the pair of pipes. It should be pointed out that the two ends of the hot melt head 20 are respectively matched socket structures, so that matching hot melt sockets can be formed for the butt ends of a pair of pipes, and the hot melt time is 2-3 minutes. After n, since the flip plate 19 is hinged with the receiving plate 16, the flip plate 19 is rotated so that the vertical plate 15 on the flip plate 19 rotates together with the flip plate 19, and then the hot melt head 20 can be flipped to make room for docking after hot melting, and the action structure is started to rotate the screw rod 3, and then the pair of slides 4 are brought close together, so as to complete the hot melting of a pair of pipes;

[0043] According to the instruction manual Figure 1-8 It can be seen that the locking assembly includes: an insert rod 24, a card 25, a nut 26, a top plate 27 and a spring 28, and their connection relationship and position relationship are as follows;

[0044] A mounting groove is provided at one end of the semicircular groove plate 11, and a plug rod 24 is inserted into the mounting groove. A card 25 is movably installed at the top of the plug rod 24, and an external thread structure is provided at the bottom of the plug rod 24. A nut 26 is installed on the lower wall of the mounting groove. The bottom end of the plug rod 24 is threadedly connected in the nut 26. A top plate 27 is provided at the top of the plug rod 24 and below the card 25. A spring 28 is sleeved on the plug rod 24 and fits with the top plate 27 and the upper wall of the mounting groove respectively.

[0045] In the specific implementation process, after the pipe is placed in the lower semicircular groove, the upper buckle ring 12 is buckled downward by adjusting the rotary handle 13, so that the upper semicircular groove buckles the upper wall of the pipe. At this time, the end of the upper buckle ring 12 is aligned with the installation groove position. The card 25 adopts an oblong structure. By rotating the card 25, the card 25 passes through the locking groove, and then rotates the card 25 90 degrees, so that the card 25 limits the upper wall of the locking groove, thereby limiting the upper buckle ring 12 and locking it. A rotating block is provided at the bottom of the plug rod 24. The rotating block is a small disk made of plastic and has a plurality of friction grooves on the side wall. At this time, rotating the rotating block will cause the plug rod 24 to move downward under the action of the nut 26, pulling the card 25 to further squeeze the locking groove, thereby increasing the fixing effect. The spring 28 is limited by the top plate 27. In this process, the plug rod 24 is stably limited and potential energy is accumulated. The potential energy is released when the card 25 is released and the plug rod 24 is rotated in the opposite direction.

[0046] According to the instruction manual Figure 1-8 It can be seen that the above-mentioned action structure includes: a driven gear 29, a power box 30, a driving motor 31 and a driving gear 32, and their connection relationship and position relationship are as follows;

[0047] A driven gear 29 is installed at the end of the screw rod 3, a power box 30 is installed on one side of the bottom plate 1, a driving motor 31 is installed in the power box 30, a driving gear 32 is installed on the driving end of the driving motor 31, and the driving gear 32 is meshed with the driven gear 29; both the driving gear 32 and the driven gear 29 are bevel gears and the gear ratio between the two is less than 0.5;

[0048] In the specific implementation process, the power box 30 is used to protect the driving gear 32, the driven gear 29 and the driving motor 31. The driving motor 31 is started so that its driving end drives the driving gear 32 to rotate, thereby making the driving gear 32 mesh with the driven gear 29, and then the driven gear 29 drives the screw rod 3 to rotate. The gear ratio between the two is less than 0.5, which increases the torque output by the driven gear 29, increases the strength when plugging, and enhances the bonding quality while making the plugging easier.

[0049] From the above, it can be seen that the overall structure of the split portable hot-melt butt welding machine is composed of three modules, in which the upper base plate 1 for providing a skeleton and the lower base plate 1 for providing a moving force are installed separately, and the working modules are installed on the upper base plate 1 skeleton by plugging. The overall structure is convenient for disassembly and installation, which increases the flexibility of the equipment and facilitates transportation and maintenance. At the same time, automatic power drive is used to complete the observation of the socket hot-melt docking. Compared with manual force, the docking effect is better and the speed is faster. The overall coordination increases the flexibility and interchangeability of the equipment, thereby reducing the cost of the equipment during use.

[0050] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
