Description

Technical Field

[0001] The utility model belongs to the technical field of plastic part rib heating welding, and specifically relates to a nozzle device for heating welding ribs of plastic parts. Background Art

[0002] Generally, complex plastic products cannot be formed in one processing step and need to be seamlessly connected with multiple components. Generally, there are two methods: bonding and welding. Generally speaking, the bonding process has low production efficiency and the adhesive has certain toxicity, which is likely to cause environmental pollution and endanger the health of production personnel. Therefore, the welding process has been more and more widely used.

[0003] Usually, we will add welding ribs to plastic parts. To enhance the welding strength, designers usually design two or more welding ribs on plastic parts. However, when melting the welding ribs, it is extremely easy to have the problem of uneven heating of the welding ribs, which is likely to cause poor flatness of the plastic part body after welding, resulting in an increase in the defective rate of plastic parts, thus seriously affecting the production efficiency. Moreover, some harmful gases will also be generated when melting the welding ribs. If not removed in time, it will endanger the life of the operator in the long run. Therefore, there is an urgent need to design a nozzle device for heating welding ribs of plastic parts to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a nozzle device for heating welding ribs of plastic parts, which solves the problems of increased defective rate of plastic parts caused by uneven heating of welding ribs and endangerment to the life safety of operators due to the failure to timely remove harmful gases.

[0005] To solve the above technical problems, the utility model provides a nozzle device for heating welding ribs of plastic parts. The nozzle device is installed on a welding device and is located above the plastic part, and includes a nozzle, a blowing device, a heating device, and an exhaust gas treatment device. A blowing channel penetrating through the upper and lower end faces of the nozzle is provided in the nozzle, and suction channels symmetrically arranged on both sides of the blowing channel are respectively provided. The inlet of the blowing channel is connected to the heating device through a pipeline, the outlet of the blowing channel is located above the welding rib of the plastic part, the heating device is connected to the blowing device through a pipeline, and the outlet of each suction channel is connected to the exhaust gas treatment device through a pipeline.

[0006] Further, the blowing device is one of a blower and a blowing machine.

[0007] Further, the heating device is one of a heater and a hot air blower.

[0008] Further, the exhaust gas treatment device is one of a suction fan, a UV photolysis purification device, and a plasma purification device.

[0009] Furthermore, the symmetrically arranged air suction channels are respectively arranged above both sides of the plastic part welding rib.

[0010] Furthermore, the pipe is one of a flexible pipe, a telescopic pipe, a pressure-resistant pipe, and a corrosion-resistant pipe.

[0011] Advantages of the present utility model: The design of the nozzle device of the present utility model effectively improves the heat uniformity of the plastic part welding rib, effectively improves the qualification rate of the plastic part, and at the same time can effectively suck out the toxic gases generated during welding melting quickly, preventing the problem that the operator's body is damaged due to long-term inhalation of toxic gases;

[0012] A blowing channel penetrating through the upper and lower end faces of the nozzle and air suction channels symmetrically arranged on both sides of the blowing channel are provided inside the nozzle. The hot air blown out by the blowing device and the heating device is blown onto the plastic part welding rib through the blowing channel, so that the plastic part welding rib melts. At the same time, the waste gas treatment device sucks out the harmful gases and hot air on both sides of the plastic part welding rib through two pipes and two air suction channels, so that the plastic part welding rib is heated evenly, and at the same time, the problem of damage to the operator's body is avoided.

Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0017] In a specific embodiment of the present utility model, as Figure 1As shown, a nozzle device for heating the welding ribs of a plastic part is specifically disclosed. The nozzle device is installed on a welding device and is located above the plastic part 5. It includes a nozzle 1, a blowing device 2, a heating device 3, and an exhaust gas treatment device 4. The nozzle 1 is provided with a blowing channel 11 that penetrates its upper and lower end faces, and suction channels 12 symmetrically arranged on both sides of the blowing channel 11. The width of the blowing channel 11 decreases sequentially from the inlet to the outlet. Preferably, it is divided into three sections. The three sections of the blowing channel 11 are the upper section, the middle section, and the lower section. The width of the upper section > the width of the middle section > the width of the lower section. Such a design weakens the hot air blown on the welding ribs 51 of the plastic part, thus effectively preventing the problem of excessive melting of the welding ribs 51 of the plastic part;

[0018] The width of the suction channel 12 decreases sequentially from the inlet to the outlet. Preferably, it is divided into two sections. The two sections of the suction channel 12 are the upper section and the lower section. The width of the upper section < the width of the lower section. Such a design enables the exhaust gas treatment device 4 to quickly suck out the gas on both sides of the welding ribs 51 of the plastic part over a large area, and when reaching the inlet of the exhaust gas treatment device 4, it can be completely processed without causing problems such as air path congestion and backflow;

[0019] The symmetrically arranged suction channels 12 are respectively arranged above both sides of the welding ribs 51 of the plastic part. The inlet of the blowing channel 11 is connected to the heating device 3 through a pipe. The outlet of the blowing channel 11 is located above the welding ribs 51 of the plastic part. The heating device 3 is one of a heater and a hot air blower, preferably a heater. The blowing device 2 is one of a blower and a blowing machine, preferably a blower. The heating device 3 is connected to the blowing device 2 through a pipe. The exhaust gas treatment device 4 is one of a suction fan, a UV photolysis purification device, and a plasma purification device. The outlet of each suction channel 12 is connected to the exhaust gas treatment device 4 through a pipe. The pipe is one of a flexible pipe, a telescopic pipe, a pressure-resistant pipe, and a corrosion-resistant pipe, preferably a corrosion-resistant pipe, and the corrosion-resistant pipe is a telescopic pipe. The design of the nozzle device effectively improves the heat uniformity of the welding ribs 51 of the plastic part, effectively improves the qualified rate of the plastic part 5, and at the same time can effectively suck out the toxic gases or hot air generated during welding and melting, preventing the problem of the operator's body being damaged due to long-term inhalation of toxic gases.

[0020] The working process of the present utility model:

[0021] Above each plastic part welding rib 51, a nozzle device is correspondingly arranged. The hot air blown by the blowing device 2 of each nozzle device is heated by the heating device 3. The heated gas enters the blowing channel 11 through a pipeline and is blown onto the plastic part welding rib 51, blowing the plastic part welding rib 51 to melt. At the same time, the waste gas treatment device 4 sucks out the hot air and harmful gases on both sides of the plastic part welding rib 51 through a pipeline and the symmetrically arranged suction channels 12, welding the melted plastic parts 5 together, effectively improving the heat uniformity of the plastic part welding rib 51, effectively improving the qualified rate of the plastic parts 5, and at the same time being able to effectively suck out the toxic gases or hot air generated during welding and melting quickly, preventing the problem that the operator's body is damaged due to long-term inhalation of toxic gases.
