Description

Technical Field

[0001] The utility model relates to a dispensing component for foam plastic products, belonging to the technical field of dispensing. Background Technique

[0002] Air conditioner water is formed when the surface temperature of the evaporator in the air conditioner is lower than the "dew point temperature" during refrigeration, and the water vapor in the air condenses into a liquid state after precooling. There is a water receiving tray at the bottom of the indoor unit of the air conditioner. After the water receiving tray stores the condensed water, it discharges it outdoors through a conduit. For reasons such as cost, lightweight, and heat insulation, the main body of the water receiving tray is usually made of foam, and a plastic pipe head is bonded at the water outlet of the water receiving tray. Currently, manual dispensing and bonding of the plastic pipe head are mostly used. When applying the glue to the surface of the water outlet, due to the long length of the water receiving tray, it is not convenient to operate, resulting in low processing efficiency and a decrease in the yield rate of the product. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a dispensing component for foam plastic products to solve the problems raised in the above background technique. The utility model improves the dispensing efficiency, evenly applies the glue to the surface of the water outlet, and improves the yield rate of the product.

[0004] To achieve the above purpose, the utility model is realized through the following technical scheme: A dispensing component for foam plastic products includes a glue storage chamber, a piston for extruding the glue is slidably installed in the glue storage chamber, a horizontally arranged through hole is opened on one side surface of the glue storage chamber, an electric push rod concentric with the through hole is arranged outside the through hole, the movable end of the electric push rod penetrates through the through hole and contacts the piston, the cylinder end of the electric push rod is connected to the glue storage chamber through an adjusting member, a guiding hole symmetrically arranged with respect to the through hole is opened on one side surface of the glue storage chamber, a guiding rod is inserted in the guiding hole, one end of the guiding rod is fixedly connected to the piston, a limiting disc is installed at the end of the guiding rod far away from the piston, a spring is arranged between the limiting disc and the guiding hole, the spring is sleeved on the guiding rod, a bent pipe is installed at the lower position of the surface of the glue storage chamber far away from the through hole, an inner cylinder for sleeving on the water outlet installed at the bottom of the air conditioner water receiving tray is installed in the vertical part of the bent pipe, there is a gap between the inner cylinder and the inner wall of the bent pipe, the lower end of the inner cylinder penetrates through the bent pipe, a plurality of dispensing holes are arranged at equal intervals in a ring shape on the outer surface of the upper end of the inner cylinder, and one end of the dispensing hole close to the center of the inner cylinder is arranged in an upward inclined manner. A travel switch for controlling the telescopic movement of the electric push rod and being pressed by the air conditioner water receiving tray is installed in the glue storage chamber.

[0005] Further, the adjusting member includes an L-shaped plate. The cylinder end of the electric push rod is fixedly connected with the L-shaped plate. A rectangular tube is sleeved on the horizontal part of the L-shaped plate. One end of the rectangular tube is fixedly connected with the glue storage chamber. A positioning screw for restricting the relative position between the rectangular tube and the L-shaped plate is threadedly connected to the end of the upper surface of the rectangular tube away from the glue storage chamber.

[0006] Further, a small hole is formed on the upper surface of the rectangular tube on the side away from the glue storage chamber. An internal thread ring concentric with the small hole is arranged above the small hole. The internal thread ring is fixedly connected with the rectangular tube. The positioning screw is threadedly connected in the internal thread ring.

[0007] Further, a through hole is formed in the bent part of the bent pipe. The lower end of the inner cylinder penetrates through the through hole. A collecting container for collecting glue is arranged below the inner cylinder.

[0008] Further, a glue adding port is installed on the upper surface of the glue storage chamber near the bent pipe. A threaded cover is threadedly connected to the upper end of the glue adding port.

[0009] Further, a blind hole is formed at the position where the piston installs the guide rod. One end of the guide rod is fixedly connected in the blind hole.

[0010] Advantages of the utility model:

[0011] 1. Insert the water outlet on the water receiving tray into the inner cylinder, and then make the water receiving tray squeeze the contact part of the travel switch, so that the electric push rod extends. The movable end of the electric push rod penetrates through the through hole and squeezes the piston. The piston squeezes the glue in the glue storage chamber, so that the glue in the glue storage chamber enters the gap between the inner cylinder and the bent pipe. Subsequently, the glue adheres to the surface of the water outlet through a plurality of dispensing holes, realizing rapid application of glue to the water outlet surface, improving the glue application efficiency, making the glue evenly applied on the water outlet surface, and improving the yield of the product.

[0012] 2. Adjust the length of the L-shaped plate in the rectangular tube, and use the positioning screw to restrict the position of the horizontal part of the L-shaped plate in the rectangular tube, realizing convenient adjustment of the distance between the electric push rod and the glue storage chamber. Thus, when the electric push rod extends, the length extending into the glue storage chamber becomes longer or shorter, and thus the distance of a single movement of the piston becomes longer or shorter, realizing adjustment of the position of the electric push rod according to the amount of glue in the glue storage chamber, and preventing the glue from overflowing between the water outlet and the inner cylinder due to the large movement range of the electric push rod driving the piston.

[0013] 3. A collecting container is arranged below the inner cylinder, and the dispensing holes are arranged to be inclined upward. Thus, when the electric push rod contracts, the glue remaining in the dispensing holes flows into the space between the inner cylinder and the bent pipe under the action of its own gravity. When the water outlet is taken out, part of the glue that enters the inner cylinder slides down into the collecting container under the action of its own gravity. Description of the drawings

Detailed implementation manners

[0022] To make the technical means, creative features, achieved objectives, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0023] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a dispensing component for a foam plastic product, including a glue storage chamber 3. A glue adding port 17 is installed on one side of the upper surface of the glue storage chamber 3 close to the bent pipe 12. The upper end of the glue adding port 17 is threadedly connected with a threaded cap 18. After removing the threaded cap 18, it is convenient to add glue into the glue storage chamber 3 through the glue adding port 17.

[0024] Refer to Figures 1 - 3, a piston 19 for extruding glue is slidably installed in the glue storage chamber 3. A horizontally arranged through hole 11 is formed in one side surface of the glue storage chamber 3. An electric push rod 10 concentric with the through hole 11 is arranged outside the through hole 11. The movable end of the electric push rod 10 penetrates through the through hole 11 and contacts the piston 19. The cylinder end of the electric push rod 10 is fixedly connected with an L-shaped plate 9. A rectangular tube 4 is sleeved on the horizontal part of the L-shaped plate 9. One end of the rectangular tube 4 is fixedly connected with the glue storage chamber 3. An internal thread ring 16 is arranged above a small hole formed in the upper surface of the rectangular tube 4 on the side far from the glue storage chamber 3. The internal thread ring 16 is concentric with the small hole and is fixedly connected with the rectangular tube 4. A positioning screw 5 for restricting the relative position between the rectangular tube 4 and the L-shaped plate 9 is screwed into the internal thread ring 16 to complete the assembly of the positioning screw 5. The length of the horizontal part of the L-shaped plate 9 in the rectangular tube 4 is adjusted, and the position of the horizontal part of the L-shaped plate 9 in the rectangular tube 4 is restricted by the positioning screw 5, so as to conveniently adjust the distance between the electric push rod 10 and the glue storage chamber 3. Thus, when the electric push rod 10 extends, the length extending into the glue storage chamber 3 becomes longer or shorter, and thus the distance of a single movement of the piston 19 becomes longer or shorter, realizing the adjustment of the position of the electric push rod 10 according to the amount of glue in the glue storage chamber 3, and preventing the glue from overflowing between the water outlet 14 and the inner cylinder 13 due to the large movement range of the electric push rod 10 driving the piston 19.

[0025] Refer to Figures 1 - 4 , a guiding hole 15 symmetrically arranged with respect to the through hole 11 is formed in one side surface of the glue storage chamber 3. A guiding rod 6 is inserted into the guiding hole 15. One end of the guiding rod 6 is installed in a blind hole formed in one surface of the piston 19. A limiting disc 8 is installed at the end of the guiding rod 6 far from the piston 19. A spring 7 is arranged between the limiting disc 8 and the guiding hole 15. The spring 7 is sleeved on the guiding rod 6. When the electric push rod 10 extends, the movable end of the electric push rod 10 passes through the through hole 11 and then extrudes the piston 19, causing the piston 19 to move. At this time, the piston 19 drives the guiding rod 6 to slide in the guiding hole 15, and at this time the spring 7 is in a compressed state. After the electric push rod 10 contracts, under the action of the resilience of the spring 7, the piston 19 is restored to a position away, facilitating the return of the glue in the space between the inner cylinder 13 and the elbow 12 to the glue storage chamber 3.

[0026] Refer to Figures 1 - 6, a bent pipe 12 is installed at the lower position of the side of the glue storage chamber 3 away from the perforation 11. An inner cylinder 13 is installed in the vertical part of the bent pipe 12 and is used to sleeved on the water outlet 14 installed at the bottom of the air conditioner water receiving tray 1. There is a gap between the inner cylinder 13 and the inner wall of the bent pipe 12. The lower end of the inner cylinder 13 penetrates through the through hole 21 opened in the bent part of the bent pipe 12. A plurality of dispensing holes 20 are arranged at equal intervals in a ring shape on the outer surface of the upper end of the inner cylinder 13. One end of the dispensing hole 20 close to the center of the inner cylinder 13 is arranged to incline upward. A collecting container is arranged on the lower side of the inner cylinder 13, and the dispensing holes 20 are arranged to incline upward. Thus, when the electric push rod 10 contracts, the glue remaining in the dispensing holes 20 flows into the space between the inner cylinder 13 and the bent pipe 12 under the action of its own gravity. When the water outlet 14 is taken out, part of the glue that enters the inner cylinder 13 slides down into the collecting container under the action of its own gravity. A travel switch 2 for controlling the telescopic movement of the electric push rod 10 and being squeezed by the air conditioner water receiving tray 1 is installed in the glue storage chamber 3. Insert the water outlet 14 on the water receiving tray 1 into the inner cylinder 13, and then make the water receiving tray 1 squeeze the contact part of the travel switch 2, so that the electric push rod 10 extends. The movable end of the electric push rod 10 penetrates through the perforation 11 and squeezes the piston 19. The piston 19 squeezes the glue in the glue storage chamber 3, so that the glue in the glue storage chamber 3 enters the gap between the inner cylinder 13 and the bent pipe 12. Subsequently, the glue adheres to the surface of the water outlet 14 through a plurality of dispensing holes 20, realizing rapid coating of the glue on the water outlet 14, improving the coating efficiency, making the glue evenly coated on the surface of the water outlet 14, and improving the yield rate of the product.
