Description

Technical Field

[0001] This utility model belongs to the field of umbrella processing technology, and in particular relates to a welding head machine for umbrella processing. Background Technology

[0002] Umbrellas are widely used in people's daily lives as a tool for sunshade or rain and snow protection. They are generally made of oiled paper, oilcloth, or plastic sheeting. For umbrella processing welding machines, it is necessary to quickly weld the top side of the umbrella fabric and the umbrella cap above it.

[0003] In the prior art, Chinese utility model patent CN215589975U discloses a welding head machine for umbrella processing, including a pressing mechanism for pressing umbrella fabric and a sealing ring together, a fixing mechanism for fixing the umbrella fabric, and a machine housing. The pressing mechanism is located on the upper side of the machine housing, and the fixing mechanism is located on the lower side of the machine housing. It also includes a welding mechanism for welding the umbrella fabric and the sealing ring. This utility model utilizes an electric ball valve, a negative pressure tank, and a vacuum pump to evacuate air from the recess on a conical welding seat. Simultaneously, the welding head engages with the recess of the welding seat to weld the umbrella fabric and the sealing ring. During this process, rapid positioning welding can be completed without manual intervention on the umbrella fabric and the sealing ring, thereby improving the welding efficiency of the umbrella fabric and the sealing ring.

[0004] In existing technologies, welding of the umbrella fabric and sealing rings is performed using an electric ball valve, a negative pressure tank, and a vacuum pump to improve the welding efficiency of the umbrella fabric and sealing rings. However, there are still some shortcomings in overall use.

[0005] First, when welding the umbrella fabric and the umbrella cap, the fiber debris, environmental dust and other pollutants attached to the surface of the fabric will hinder the transmission of ultrasonic energy, resulting in poor fusion at the welding interface, producing defects such as incomplete welding or insufficient strength, which will lead to water leakage.

[0006] Secondly, during the welding of the umbrella fabric and the umbrella cap, the high temperature at the moment of welding will melt the contact surface between the umbrella fabric and the umbrella cap. It is necessary to cool the material to solidify and shape it quickly to avoid deformation of the joint surface due to external force in the molten state. At the same time, if the cooling time is too long, the umbrella fabric fibers will harden, reduce flexibility, and affect product quality. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, this invention provides a welding head machine for umbrella processing. This invention solves the problem that pollutants such as fiber debris and environmental dust adhering to the umbrella fabric surface can hinder the transmission of ultrasonic energy, leading to water seepage. It also addresses the issue of excessively long cooling times affecting product quality.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a welding head machine for umbrella processing, comprising a base, a processing table fixedly mounted on the upper surface of the base, a support platform fixedly mounted on the upper surface of the processing table, a semi-circular protrusion fixedly mounted on the upper surface of the support platform for supporting the umbrella fabric, a conical placement block fixedly mounted on the top of the protrusion for placing the umbrella cap, an installation plate slidably disposed above the placement block, a welding head for use with the placement block fixedly mounted on the lower surface of the installation plate, a conical pressure plate slidably disposed on the outer side of the welding head, a ring tube fixedly mounted on the inner surface of the pressure plate, and multiple inwardly inclined nozzles disposed at the bottom of the ring tube.

[0009] By using pressure plates, pressure blocks, ring tubes, and nozzles, dust on the umbrella fabric can be blown away and the fabric can be flattened during welding, preventing poor fusion at the welding interface and greatly improving the welding effect. After welding, the welding interface can also be cooled quickly, further enhancing the welding effect.

[0010] In the aforementioned welding head machine for umbrella processing, a plurality of guide posts are fixedly installed on the upper surface of the pressure plate and slide through the interior of the mounting plate, and a spring through which the guide posts pass is fixedly installed between the upper surface of the pressure plate and the lower surface of the mounting plate.

[0011] By using guide posts and springs, the umbrella fabric remains stable during welding, thereby improving welding quality. The springs keep the pressure on the upper surface of the umbrella fabric, preventing excessive pressure from damaging the fabric and greatly enhancing its performance.

[0012] In the aforementioned welding head machine for umbrella processing, multiple pressure blocks are fixedly installed on the lower surface of the pressure plate, and an exhaust groove is formed between each pressure block.

[0013] By setting up exhaust channels, airflow and dust can be discharged, greatly improving the dust removal and leveling effects.

[0014] In the aforementioned welding head machine for umbrella processing, the upper surface of the pressure plate has a through hole through which the welding head passes.

[0015] The through-hole design facilitates subsequent welding work and allows the umbrella fabric to be kept flat during welding, greatly improving the welding effect.

[0016] In the aforementioned welding head machine for umbrella processing, a column is fixedly installed on the upper surface of the processing table, a top plate is fixedly installed on the upper surface of the column, a pressing cylinder is fixedly installed on the upper surface of the top plate, and the output end of the pressing cylinder slides through the top plate and is fixed to the upper surface of the mounting plate.

[0017] In the aforementioned welding head machine for umbrella processing, an air pump is fixedly installed on the upper surface of the top plate and on one side of the pressing cylinder, and a filter screen is fixedly installed at the air inlet end of the air pump.

[0018] By using a filter, dust in the air can be filtered out, preventing external dust from blowing onto the surface of the umbrella fabric and greatly improving its performance.

[0019] In the aforementioned welding head machine for umbrella processing, the air pump's outlet is connected to a conduit, which is connected to a ring pipe.

[0020] In the aforementioned welding head machine for umbrella processing, the surface of the support platform is provided with an arc-shaped mounting cavity, and a top ring is slidably installed inside the mounting cavity.

[0021] With the installation cavity and top ring, the umbrella fabric can be quickly ejected after the welding and cooling of the umbrella fabric and the umbrella cap, without the need for manual operation, which greatly improves the discharge speed and thus improves work efficiency.

[0022] In summary, compared with the prior art, the welding head machine for umbrella processing provided by this utility model has the following beneficial effects:

[0023] 1. In this utility model, by setting up a pressure plate, pressure block, ring tube and nozzle, the dust on the umbrella fabric can be blown away and the umbrella fabric can be flattened at the same time during welding, so as to avoid poor fusion of the welding interface and greatly improve the welding effect. After welding is completed, the welding interface can also be cooled quickly, which greatly improves the welding effect.

[0024] 2. In this utility model, by setting up the installation cavity, top ring, etc., the umbrella fabric can be quickly pushed out after the welding and cooling of the umbrella fabric and the umbrella cap is completed, without the need for manual operation by the operator, which greatly improves the discharge speed and thus improves work efficiency.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] Example 1:

[0034] refer to Figure 1 A welding head machine for umbrella processing includes a base 10, a processing table 11 fixedly mounted on the upper surface of the base 10, a support platform 12 fixedly mounted on the upper surface of the processing table 11 for placing the umbrella fabric, a hemispherical protrusion 13 fixedly mounted on the upper surface of the support platform 12 for supporting the umbrella fabric, conforming to the shape of the umbrella to facilitate welding of the umbrella fabric and the umbrella cap, and a conical placement block 14 fixedly mounted on the top of the protrusion 13 for placing the umbrella cap. In use, the middle hole of the umbrella fabric is passed through the placement block 14 and placed on the upper surface of the support platform 12. The protrusion 13 lifts the middle part of the umbrella fabric, and the outer circular surface of the protrusion 13 supports the umbrella fabric to form a hemispherical shape. Then, the umbrella cap is put on the surface of the placement block 14 so that the bottom of the umbrella cap abuts against the upper surface of the umbrella fabric.

[0035] Further reference Figure 1 A column 15 is fixedly installed on the upper surface of the base 10. A top plate 16 is fixedly installed on the top of the column 15. A pressing cylinder 17 is fixedly installed on the upper surface of the top plate 16. The output end of the pressing cylinder 17 slides through the top plate 16, and an installation plate 18 is fixedly installed at the bottom end. A cone-shaped welding head 19 for use with the umbrella cap is fixedly installed on the lower surface of the installation plate 18. After the umbrella cap and umbrella fabric are placed, the pressing cylinder 17 is controlled to move the installation plate 18 and the welding head 19 downward. The umbrella fabric and umbrella cap are ultrasonically welded through the welding head 19. It should be noted that the welding head 19 is a conventional ultrasonic welding head, which will be equipped with corresponding welding equipment in actual use. However, it is existing technology, so this solution will not elaborate on it.

[0036] Further reference Figure 1 and Figure 4Multiple guide posts 20 that slide through the mounting plate 18 are provided on the outer side of the welding head 19. A conical pressure plate 21 is fixedly installed at the bottom end of the guide post 20. Multiple pressure blocks 22 are fixedly installed on the lower surface of the pressure plate 21. A spring 23 that is penetrated by the guide post 20 is fixedly installed between the upper surface of the pressure plate 21 and the lower surface of the mounting plate 18. When the welding head 19 moves downward to weld, the guide post 20 drives the pressure plate 21 to move downward, thereby driving the spring 23 to move downward as well. This causes the pressure blocks 22 to press on the umbrella fabric, thus completing the positioning of the umbrella fabric. This keeps the umbrella fabric stable during welding, thereby improving the welding quality. The spring 23 keeps the pressure blocks 22 pressed on the upper surface of the umbrella fabric, avoiding excessive pressure that could damage the fabric. At the same time, the guide post 20 moves upward through the mounting plate 18, keeping the pressure blocks 22 stable when moving downward.

[0037] Further reference Figure 1 , Figure 3 and Figure 5 An image recognition device 30 is fixedly installed on the upper surface of the base 10. The image recognition device 30 is existing technology and will not be described in detail in this solution. A ring tube 26 is fixedly installed inside the pressure plate 21. Multiple inwardly inclined nozzles 27 are provided at the bottom of the ring tube 26 to facilitate the removal of dust from the umbrella fabric. An exhaust groove 28 is formed between each pressure block 22. An air pump 24 is fixedly installed on the upper surface of the top plate 16. A filter screen is provided at the air inlet end of the air pump 24 to filter dust in the air. A duct 25 is connected to the air outlet end of the air pump 24, and the duct 25 is connected to the ring tube 26.

[0038] In use, when the image recognizer 30 detects that the pressure plate 21 moves downward, the air pump 24 starts working, inflating the ring pipe 26 through the conduit 25 and spraying it evenly through the nozzle 27. This blows air downwards onto the umbrella fabric located on the protrusion 13, flattening the fabric with air pressure and removing dust from its surface, greatly improving welding quality. After flattening the fabric and removing dust, the pressure block 22 presses down on the fabric for fixation. The exhaust groove 28 allows airflow to escape. When the image recognizer 30 detects that the pressure block 22... When the umbrella fabric is pressed down, the air pump 24 stops working. At this time, the welding head 19 welds the umbrella fabric and the umbrella cap. After the welding is completed, the image recognition device 30 detects that the welding head 19 moves upward. At this time, the air pump 24 starts working, so that the nozzle 27 sprays air to blow and cool the welded joint between the umbrella fabric and the umbrella cap, thereby increasing the cooling speed and avoiding the umbrella fabric fibers from hardening due to excessive cooling time, which would reduce flexibility and greatly improve the performance. When the image recognition device 30 detects that the pressure plate 21 and the pressure block 22 move upward, the air pump 24 stops working.

[0039] Example 2:

[0040] refer to Figure 2 and Figure 6Two ejector cylinders 31 are fixedly installed inside the base 10. These ejector cylinders 31 are the same as the pressing cylinder 17. The output end of the ejector cylinder 31 slides through the upper surface of the processing table 11. An annular mounting cavity 32 is opened on the upper surface of the support 12. A top ring 33 is slidably installed inside the mounting cavity 32. After the output of the ejector cylinder 31 slides through the support 12, it is fixed to the lower surface of the top ring 33. When the umbrella fabric and the umbrella cap are welded and cooled, the ejector cylinder 31 drives the top ring 33 to move upward, thereby ejecting the umbrella fabric from the placement block 14, which greatly improves the ejection speed and improves work efficiency.

[0041] Working principle: During operation, the middle hole of the umbrella fabric is passed through the placement block 14 and placed on the upper surface of the support platform 12. The protrusion 13 lifts the middle of the umbrella fabric. Then, the umbrella cap is put on the surface of the placement block 14 so that the bottom of the umbrella cap abuts against the top of the umbrella fabric. The welding head 19 moves downward to perform ultrasonic welding on the umbrella fabric and the umbrella cap. When the image recognition device 30 detects that the pressure plate 21 moves downward, it blows air from top to bottom on the umbrella fabric. The air pressure flattens the umbrella fabric and removes dust from its surface. The pressure block 22 presses down on the umbrella fabric to fix it. At this time, the welding head 19 welds the umbrella fabric and the umbrella cap. After welding, the nozzle 27 sprays air to cool the weld between the umbrella fabric and the umbrella cap. After cooling, the ejector cylinder 31 drives the top ring 33 to move upward, thereby ejecting the umbrella fabric from the placement block 14.
