Abstract
Description
Technical Field
[0001] The utility model relates to the field of foam machines, in particular to a new type of polyurethane foam machine. Background Art
[0002] In the prior art of polyurethane foam machines, there are two key problems to be solved urgently, which are directly related to the use efficiency, finished product quality and long-term stability of the foam machines;
[0003] Firstly, regarding the residue problem at the nozzle during the foaming process, after the foaming operation of the existing foam machines is completed, due to the viscosity and fluidity characteristics of the polyurethane foam glue, there is often some foam glue remaining at the nozzle and its surrounding area; if these residues are not processed in time, they will not only drip onto the workpieces or workbenches during subsequent foaming operations, causing product appearance pollution and quality decline, but also may increase the additional cleaning workload and time cost; more seriously, the residues accumulated over a long period may block the nozzle, affecting the normal discharging of the foam machine, thereby reducing the production efficiency and increasing the complexity of equipment maintenance;
[0004] Secondly, during the period when the foam machine is not in use or under shutdown maintenance, the foam glue is prone to hardening in the nozzle and the conveying pipeline; this phenomenon has a profound impact on the foam machine: on the one hand, the hardened foam glue will firmly adhere to the inner wall of the nozzle and the pipeline, resulting in abnormal discharging when used again, and a large amount of time and resources must be consumed for cleaning and dredging; on the other hand, serious hardening may cause irreversible damage to the mechanical structure of the nozzle, requiring the replacement of the entire nozzle, thus increasing the equipment maintenance cost; in addition, the inspection and cleaning work before each startup also prolongs the production preparation time and reduces the overall production efficiency.
[0005] Therefore, it is necessary to provide a new type of polyurethane foam machine to solve the above technical problems. Content of the Utility Model
[0006] To solve the above technical problems, the utility model provides a new type of polyurethane foam machine.

[0015] Compared with the related art, the new polyurethane foaming machine provided by the present utility model has the following beneficial effects:
[0016] Efficient cleaning of residual foaming glue: After the polyurethane foaming machine discharges materials, the rotary motor rotates forward 90 degrees, so that the material receiving hopper accurately rotates to the directly below of the discharge port of the foaming machine; this design cleverly captures the possible residual foaming glue, effectively avoiding the foaming glue from dripping on the workbench, thereby reducing product contamination and cleaning work; this immediate and effective residual treatment method significantly improves the cleanliness and production efficiency of the production site;
[0017] Automated maintenance, reducing downtime: When the foaming machine is not in use, the rotary motor rotates backward 90 degrees, automatically placing the grinding rod at the axis position of the nozzle; then, the electric push rod pushes the grinding rod deep into the nozzle, combined with the power of the grinding motor, through the meshing of the driving gear and the driven gear, to realize the overall grinding of the nozzle; this process not only effectively removes the residues and hardened substances inside the nozzle, but also avoids the cumbersome manual disassembly and cleaning, reduces the downtime of equipment maintenance, and improves the overall production efficiency;
[0018] Extending the equipment life and reducing the maintenance cost: Regular automated grinding maintenance not only ensures the unobstructed nozzle, but also prevents equipment damage caused by the accumulation and hardening of residues; this preventive maintenance measure extends the service life of the foaming machine and reduces the production interruption and maintenance cost caused by equipment failures.

[0027] The working principle of the novel polyurethane foaming machine provided by the utility model is as follows:
[0028] 1. Basic working process
[0029] By integrating components such as the rotary motor 7, the material receiving hopper 5, the grinding rod 6, the electric push rod 10, the grinding motor 12 and the gear transmission system, etc., the novel polyurethane foaming machine realizes the automatic treatment of residues during the foaming process and the automatic maintenance when the equipment stops;
[0030] 2. Foaming operation and residue treatment
[0031] Foaming operation: During the foaming process, the polyurethane foaming machine sprays the foaming glue from the nozzle according to the set parameters and procedures to form the required foam body;
[0032] Residue treatment: After the foaming operation is completed, the rotary motor 7 receives a forward rotation instruction, drives the cross bar 4 and the material receiving hopper 5 thereon to rotate 90 degrees, so that the material receiving hopper 5 is accurately located directly below the discharge port of the foaming machine; at this time, if there is residual foaming glue at the discharge port of the foaming machine, it will be timely captured by the material receiving hopper 5 to prevent it from dripping on the workpiece or the workbench;
[0033] 3. Shutdown maintenance and grinding treatment
[0034] Positioning of the grinding rod 6: When the polyurethane foaming machine is not in use, the rotary motor 7 receives a reverse rotation instruction, drives the cross bar 4 and the grinding rod 6 thereon to rotate 90 degrees, so that the axis of the grinding rod 6 coincides with the axis of the nozzle 3;
[0035] Grinding operation: Subsequently, the electric push rod 10 is activated to push the grinding rod 6 along the cross bar 4 towards the nozzle 3 until the grinding rod 6 is inserted into the interior of the nozzle 3. At this time, the grinding motor 12 is activated, driving the driven gear 14 to rotate through the driving gear 13, thereby driving the grinding rod 6 to perform a grinding operation inside the nozzle 3. During this process, the spiral design on the grinding rod 6 helps to enhance the grinding effect and thoroughly remove the residues and hardened substances inside the nozzle 3.
[0036] 4. Automation and intelligent control
[0037] Control system: The controller 15 at the top of the connecting seat 2 serves as the center of the entire system, responsible for receiving and processing signals from various sensors and sending corresponding control instructions to the actuators such as the rotating motor 7, the electric push rod 10, and the grinding motor 12. Through preset programs and algorithms, the controller 15 can achieve automated and intelligent control, ensuring the high efficiency, accuracy, and reliability of the entire processing process.
