[0001] The utility model relates to the technical field of plastic storage tank processing, in particular to automatic positioning welding equipment for small plastic storage tanks. Background Art

[0002] Plastic welding machine is a kind of equipment specially used for welding plastic materials. Plastic welding is a process of heating and melting two or more plastic parts and then cooling and solidifying them together. This method is usually used to connect or repair plastic products such as tanks, pipes, containers, parts, etc.

[0003] When the automatic positioning welding equipment for small plastic storage tanks in the prior art is working, it is necessary to first place the mold on a roller frame, and then use a plastic extrusion welding gun to cover the flowing plastic raw material on the mold. During this process, in order to make each plastic part bonded and the plastic and the mold fit together, a heating gun is also required to heat the mold surface. Since the position of the heating gun is always in a fixed state, and the flame is divided into three layers with different temperatures, the heating temperature of the mold surface will be inconsistent, resulting in inconsistent adhesion between plastics and inconsistent fit between plastics and the mold, which in turn affects the welding quality of the plastic storage tank.

[0004] Therefore, it is necessary to design automatic positioning welding equipment for small plastic storage tanks to solve the above problems. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Under the action of the rotating joint 13, when the heating cylinder 6 rotates, oxygen and other substances required for heating and combustion can always be connected to the inside of the heating cylinder 6, a plurality of nozzles 7 are installed on the inner side of the heating cylinder 6, and the nozzles 7 are connected to the inside of the heating cylinder 6, a rotating component for driving the heating cylinder 6 to rotate is provided on the fixed cylinder 4, and a swinging component for driving the heating cylinder 6 to swing is also provided on the rotating cylinder 5.

[0024] Reference Figure 2 and Figure 3The rotating assembly includes a motor 8, a gear 9 and a ring gear 12. The motor 8 is fixedly mounted on the fixed cylinder 4. The fixed cylinder 4 is provided with an opening 10. The gear 9 is located inside the opening 10. The gear 9 is fixedly sleeved on the output shaft of the motor 8. The rotating cylinder 5 is provided with a placement groove 11. The ring gear 12 is fixedly sleeved on the rotating cylinder 5, and the ring gear 12 is located in the placement groove 11. The ring gear 12 is meshed with the gear 9. Under the action of the motor 8, the heating cylinder 6 can rotate, so that the nozzle 7 can rotate around the area to be heated in the mold, reducing the temperature difference in the area to be heated and ensuring the preparation quality of the plastic storage tank.

[0025] Reference Figure 3-5 The swing assembly includes two moving blocks 15. Two moving grooves 14 are provided on the inner side of the rotating cylinder 5. The moving block 15 is located inside the moving groove 14, and the moving block 15 is fixed to the outer side of the heating cylinder 6. Two springs 16 are provided inside the moving groove 14. The spring 16 is used to reset the heating cylinder 6 to achieve the purpose of swinging the heating cylinder 6. The two ends of the spring 16 are respectively connected to the side wall of the moving block 15 and the inner side of the moving groove 14. The swing assembly also includes a driving member, which is used to drive the heating cylinder 6 to move. The driving member is arranged on the heating cylinder 6 and the fixed cylinder 4.

[0026] Reference Figure 3 and Figure 5 The driving member includes a plurality of protrusions 17 and a control block 18. The control block 18 is fixedly connected to the side wall of the fixed tube 4. The control block 18 is arranged opposite to the side wall of the heating tube 6. The protrusion 17 is fixedly connected to the side wall of the heating tube 6. The control block 18 is L-shaped. When the control block 18 contacts the protrusion 17, the protrusion 17 will be squeezed to move the heating tube 6, so that the area to be heated can be fully and evenly heated.

[0027] Reference Figure 2 and Figure 3 , a plurality of nozzles 7 are arranged at equal intervals in the circumferential direction, so that when the heating cylinder 6 rotates at a uniform speed and swings regularly, the nozzles 7 can evenly contact the mold surface to ensure heating consistency.

[0028] Reference Figure 3 , a plurality of protrusions 17 are arranged at equal intervals in the circumferential direction, so that the protrusions 17 and the control block 18 can maintain intermittent contact, so that the heating cylinder 6 can swing regularly to ensure the uniformity of the nozzle 7 heating the mold surface. The protrusion 17 has a hemispherical structure, which reduces the friction between the control block 18 and prolongs the service life of the device.

[0029] The specific working principle of the utility model is as follows:

[0030] During operation, the staff first places the roller mold on the roller frame 1, and the mold passes through the heating cylinder 6. Under the action of the roller and driving device of the roller frame 1, the mold will rotate on the roller frame 1, and the motor 8 will be started. The output shaft of the motor 8 will rotate to drive the gear 9 to rotate, so that the gear ring 12 will rotate, and then the rotating cylinder 5 and the heating cylinder 6 will rotate. Under the action of the rotary joint 13, the flame can be ejected through the nozzle 7 to heat the mold surface, and the heating cylinder 6 rotates in the opposite direction to the mold, so that the mold surface can be evenly and fully heated, ensuring the heating effect of the device on the mold, and then ensuring the consistency and uniformity of plastic welding;

[0031] During the rotation of the heating tube 6, when the protrusion 17 contacts the control block 18, the control block 18 squeezes the protrusion 17, so that the protrusion 17 drives the heating tube 6 to move in the direction away from the control block 18. At this time, the moving block 15 also moves with the heating tube 6, causing the spring 16 to deform. When the protrusion 17 does not contact the control block 18, under the elastic force of the spring 16, the heating tube 6 moves in the opposite direction and resets. The above steps are repeated. The heating tube 6 can swing under the action of several protrusions 17 and rotate under the action of the motor 8 at the same time. This increases the contact area between the flame sprayed by the nozzle 7 and the mold, reduces the temperature difference of the heated part of the mold surface, and thus ensures the consistency of the bonding between the plastics, while ensuring the sealing performance of the plastic storage tank and improving the quality of production and processing.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
