Description

Technical Field

[0001] The utility model belongs to the technical field of sealants, and particularly relates to an anti-clogging nozzle for butyl sealant. Background Technique

[0002] Butyl sealant is a one-component, environmentally friendly non-curing self-adhesive sealant processed from butyl rubber through a special process. It has excellent weather aging resistance, heat resistance, acid and alkali resistance, as well as excellent airtightness and electrical insulation performance. It is one of the four sealants with the largest consumption in the world and is widely used in industries such as automobiles, construction, and industry. During the production, processing, or extrusion process of butyl sealant, an extrusion device often needs to be equipped with a nozzle to facilitate the control of the extrusion amount and extrusion speed. To prevent the sealant remaining on the surface and inner wall of the nozzle from curing and causing nozzle blockage, an anti-clogging structure is often set when the nozzle is in use to ensure the service life of the nozzle and the normal progress of production and processing. However, it still has the following drawbacks in actual use:

[0003] The utility model with the publication number CN217140959U discloses an extrusion device for preventing blockage and cleaning the outlet in sealant processing. An inlet is arranged above the main body of the extruder, and an anti-blocking component for preventing blockage of the inlet is arranged at the inlet. The anti-blocking component, the second driving motor, the driving shaft, the first rolling block, the bearing, the first gear, the second gear, and the second rolling block are provided. The output end of the second driving motor is provided with a driving shaft, and a first rolling block is sleeved outside the driving shaft. One end of the driving shaft away from the second driving motor is provided with a bearing. Although the device can avoid blockage of the discharge head by cleaning the discharge head with water, it will lead to an increase in production costs and the amount of sewage, and it is difficult for the flowing water to spray deep into the discharge head, and there may still be residual sealant in the deep part of the discharge head, resulting in poor cleaning effect;

[0004] When the sealant nozzle is in use, when it is necessary to replace the nozzle to adjust the sealant extrusion amount and extrusion speed, replacing the nozzle will cause air to contact the inside of the nozzle and the interface of the spraying device. The air may contaminate the sealant inside the nozzle and the interface of the spraying device, and may cause blockage of the interface of the spraying device and the inside of the nozzle. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-clogging nozzle for butyl sealant. Through the replaceable nozzle and the connecting frame, the problems that it is difficult to wash deep into the nozzle by water flushing, there may still be residual sealant blocking the nozzle, and water flushing increases production costs and the amount of sewage treatment are solved. When replacing the nozzle of the spraying device, air will contact the inside of the removed nozzle and the interface of the spraying device, contaminating the sealant inside the nozzle and the interface of the spraying device, and may cause blockage of the interface of the spraying device and the inside of the nozzle.

[0006] To solve the above technical problems, the present utility model is realized through the following technical solutions:

[0007] The present utility model is an anti-blocking nozzle for butyl sealant, which includes a replaceable nozzle and a connecting frame. The first sealing magnetic attraction slider and the second sealing magnetic attraction slider are inserted through both ends of the replaceable nozzle. A first electromagnet is arranged inside the replaceable nozzle. One end of the replaceable nozzle is rotatably fixed with a connecting frame, and magnetic attraction sliding plates are slidably clamped at both ends inside the connecting frame;

[0008] When the replaceable nozzle is not in use, the first sealing magnetic attraction slider and the second sealing magnetic attraction slider seal both ends of the replaceable nozzle, preventing air from contacting the residual sealant inside the replaceable nozzle and avoiding blockage of the sealant. Moreover, after using the sealant spraying device, the power supply to the first electromagnet is cut off, causing the first sealing magnetic attraction slider and the second sealing magnetic attraction slider to slide back to their original positions, which can scrape out the residual sealant in the first chute. The residual sealant will move along with the first sealing magnetic attraction slider and the second sealing magnetic attraction slider, causing the sealant at one end of the first sealing magnetic attraction slider to adhere to one end of the first sealing magnetic attraction slider. When there is a large amount of adhesion, it can be directly removed by applying force. The sealant at one end of the second sealing magnetic attraction slider retreats to the inner side of the connecting frame, further preventing residual sealant at both ends of the first chute. When the replaceable nozzle is removed and replaced, there is basically no residual sealant on the outer wall of the replaceable nozzle, enabling the replaceable nozzle to be directly stored without the need to clean the replaceable nozzle, improving the convenience of use. When the replaceable nozzle is removed, the second electromagnet releases the adsorption on the magnetic attraction sliding plate, and the magnetic attraction sliding plate quickly slides and closes one end of the second material feeding groove, preventing air from contacting the residual sealant in the second material feeding groove and avoiding blockage inside the connecting frame.

[0009] Further, a threaded pipe is welded and fixed to one end of the replaceable nozzle, and a first power supply connection component is clamped and fixed to one end of the replaceable nozzle. The first sealing magnetic attraction slider is located at the other end of the replaceable nozzle relative to the first power supply connection component and the threaded pipe;

[0010] The first power supply connection component enables the power connection between the replaceable nozzle and the connecting frame, facilitating the control of the first electromagnet. When sealant spraying and extrusion are required, the first electromagnet adsorbs the first sealing magnetic attraction slider and the second sealing magnetic attraction slider, enabling the sealant to flow inside the replaceable nozzle and improving the convenience of nozzle use.

[0011] Further, a first chute is opened through one end of the replaceable nozzle, and a first material feeding groove is opened inside the replaceable nozzle. Both ends of the first material feeding groove are respectively connected through and communicated with both ends of the first chute;

[0012] When the sealant passes through the replaceable nozzle, it first enters one end of the first chute, then moves to the other end of the first chute through the first material passage groove, and is extruded through the other end of the first chute. When the sealant is not in use, the first sealing magnetic slider and the second sealing magnetic slider can close both ends of the first material passage groove, preventing air from contacting the residual sealant in the first material passage groove. Moreover, a small amount of sealant can be stored in the first material passage groove for convenient use next time, reducing the waste of residual sealant.

[0013] Further, the first electromagnet is snap-fitted and fixed in the first chute. One end of the first sealing magnetic slider is snap-fitted with a first return spring, and one end of the second sealing magnetic slider is snap-fitted with a second return spring. One ends of the first return spring and the second return spring are respectively snap-fitted on both sides of the first electromagnet. The first sealing magnetic slider and the second sealing magnetic slider are respectively inserted through both ends of the first chute.

[0014] When the sealant is sprayed and extruded, the first electromagnet is energized to adsorb the first sealing magnetic slider and the second sealing magnetic slider, enabling the sealant to be extruded through the replaceable nozzle. After use, the first electromagnet is de-energized. The first sealing magnetic slider and the second sealing magnetic slider are reset under the elastic force of the first return spring and the second return spring, and the residual sealant in the first chute is scraped out. The sealant at one end of the first sealing magnetic slider adheres to one end of the first sealing magnetic slider and can be directly removed by applying force when there is a large amount of adhesion. The sealant at one end of the second sealing magnetic slider retracts inside the connecting frame, preventing the replaceable nozzle from being blocked. Moreover, when the replaceable nozzle is removed and replaced, there is basically no residual sealant on the outer wall of the replaceable nozzle, enabling the replaceable nozzle to be directly stored, improving the convenience of use.

[0015] Further, one end of the connecting frame is welded and fixed with a mounting plate. The other end of the outer peripheral surface of the connecting frame is provided with a threaded groove. The outer peripheral surface of the connecting frame is provided with a power connection port. One end of the connecting frame is snap-fitted and fixed with a second power connection component. The second power connection component is located at the other end of the connecting frame relative to the mounting plate. The threaded tube is screwed and fixed on the outer peripheral surface of the threaded groove. The second power connection component is attached to one side of the first power connection component.

[0016] The nozzle and the extrusion device are installed and connected through the mounting plate. When it is necessary to replace nozzles of different diameters, only the replaceable nozzle needs to be unscrewed and removed, without removing the connecting frame, improving the convenience of operation.

[0017] Furthermore, a second material passage groove is formed through one end of the connecting frame. Second sliding grooves are formed at both ends inside the second material passage groove. Two magnetic attraction sliding plates are slidably clamped inside the second sliding grooves. Second electromagnets are clamped at both ends inside the second sliding grooves. One end of each magnetic attraction sliding plate is clamped with a third return spring, and the other end of the third return spring is clamped inside the second sliding groove. The first sliding groove and the second material passage groove are connected through. The second sealed magnetic attraction slider is attached to one side of the magnetic attraction sliding plate;

[0018] When using the sealant, the second electromagnet is energized to attract the magnetic attraction sliding plate, so that the magnetic attraction sliding plate moves to open the second material passage groove, and the sealant can enter the replaceable nozzle through the second material passage groove. When the replaceable nozzle needs to be replaced, the second electromagnet is powered off, so that the magnetic attraction sliding plate resets under the elastic force of the third return spring and closes one end of the second material passage groove, avoiding the contact between air and the residual sealant in the second material passage groove, and avoiding blockage in the connecting frame.

[0019] The utility model has the following beneficial effects:

[0020] By providing a replaceable nozzle, the utility model solves the problem that although the device can avoid blockage of the discharge head by cleaning the discharge head with water, it will increase the production cost and the amount of sewage, and the flowing water is difficult to spray into the deep part of the discharge head, and there may still be residual sealant in the deep part of the discharge head, resulting in poor cleaning effect. After the sealant is extruded, the first electromagnet is powered off, so that the first sealed magnetic attraction slider and the second sealed magnetic attraction slider reset under the elastic force, extruding the residual sealant in the first sliding groove and closing the port of the replaceable nozzle at the same time, avoiding air pollution to the sealant in the replaceable nozzle. When there is a lot of sealant attached to one end of the first sealed magnetic attraction slider, it can be directly removed by applying force. There is basically no residual sealant on the outer wall of the replaceable nozzle, and it is not necessary to clean it every time after use, improving the convenience of use.

[0021] By providing a replaceable nozzle and a connecting frame, the utility model solves the problem that when using a sealant nozzle, when the nozzle needs to be replaced to adjust the sealant extrusion amount and extrusion speed, replacing the nozzle will cause air to contact the inside of the nozzle and the interface of the spraying device, and the air may pollute the sealant inside the nozzle and the interface of the spraying device, and may cause blockage of the interface of the spraying device and the inside of the nozzle. After the sealant is extruded, the first electromagnet is powered off, and the second sealed magnetic attraction slider resets under the elastic force and pushes the residual sealant at one end in the first sliding groove back to the inside of the connecting frame. When the replaceable nozzle needs to be replaced, the second electromagnet is powered off, so that the magnetic attraction sliding plate moves under the elastic force and closes one end of the second material passage groove, and scrapes off the sealant at the end of the second sealed magnetic attraction slider. When the replaceable nozzle is unscrewed and removed, air will not contact the residual sealant in the second material passage groove, avoiding blockage in the connecting frame.
