Technical Field

[0001] This utility model relates to the field of leather processing technology, and specifically to a leather adhesive spraying device for uniform adhesive spraying. Background Technology

[0002] Leather goods refer to various products made primarily of leather, covering multiple areas such as daily life, fashion accessories, and home decoration.

[0003] In the leather goods production process, the edges of two pieces of leather are usually glued together by spraying adhesive. However, the current adhesive spraying equipment has a simple structure, which makes it easy for the adhesive to be exposed during the spraying process, causing the sprayed area to expand and thus affecting the width of the subsequent bonding. In addition, uneven spraying is prone to occur during the spraying process, affecting the bonding strength. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a leather adhesive spraying device that sprays adhesive evenly, and the adhesive is applied evenly and with equal width along the edge by means of bonding, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a leather glue spraying device for uniform glue spraying, including a glue injection shell, a placement seat, and a leather item to be sprayed with glue. One end of the glue injection shell narrows inward to form a glue outlet tube. A U-shaped frame glue is provided on the open end face of the glue outlet tube. A glue outlet channel is formed between one side of the U-shaped frame glue and the end face of the glue outlet tube. One side of the U-shaped frame glue protrudes to form a side portion. The U-shaped frame glue is placed on the surface of the leather item to be sprayed with glue, and the side portion is set on the side of the leather item to be sprayed with glue. The placement seat includes a side plate, a rubber layer, and multiple fixing blocks. The fixing blocks are all installed on one side of the side plate, and positioning channels are formed between the fixing blocks. The rubber layer is installed on the fixing block on one side.

[0006] As a preferred technical solution, a positioning sleeve is installed on the outside of the U-shaped frame adhesive, and the other end of the positioning sleeve is fitted onto the dispensing tube. A support plate is installed on the side of the positioning sleeve facing the side, and the inner side of the support plate is bonded and fixed to the outer side of the side. The width of the support plate matches the width of the positioning channel.

[0007] As a preferred technical solution, the length and width of the inner cavity of the positioning sleeve match the length and width of the dispensing tube. The dispensing tube has first screw holes on both sides, and the positioning sleeve has second screw holes on both sides. The corresponding first screw holes and second screw holes are threaded with hand-tightening bolts.

[0008] As a preferred technical solution, positioning holes are provided on the side plate.

[0009] As a preferred technical solution, the top surface of the rubber layer is flush with the bottom surface of the U-shaped frame adhesive, and a sealing part is formed by protrusion on the rubber layer, the length of which matches the length of the adhesive outlet channel.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention discloses a leather glue spraying device for uniform glue spraying, comprising a glue injection shell 1, a placement seat, and a leather item 2 to be sprayed with glue. One end of the glue injection shell 1 narrows inward to form a glue outlet tube 16. A U-shaped frame glue 14 is provided on the open end face of the glue outlet tube 16. A glue outlet channel 15 is formed between one side of the U-shaped frame glue 14 and the end face of the glue outlet tube 16. One side of the U-shaped frame glue 14 protrudes to form a side part 5. The U-shaped frame glue 14 is placed on the surface of the leather item 2 to be sprayed with glue, and the side part 5 is set on the side of the leather item to be sprayed with glue. The placement seat includes a side plate 9, a rubber layer 10, and multiple fixing blocks 8. The fixing blocks 8 are all installed on one side of the side plate 9, and a positioning channel 13 is formed between the fixing blocks 8. The rubber layer 10 is installed on one side of the fixing block 8.

[0024] The sides and U-shaped frame are made of rubber to ensure a tight seal during subsequent use.

[0025] In this embodiment, a positioning sleeve 3 is installed on the outside of the U-shaped frame adhesive 14. The other end of the positioning sleeve 3 is fitted onto the adhesive tube 16. A support plate 4 is installed on the side of the positioning sleeve 3 facing the side 5. The inner side of the support plate 4 is bonded and fixed to the outer side of the side 5. The width of the support plate 4 matches the width of the positioning channel 13.

[0026] In this embodiment, the length and width of the inner cavity of the positioning sleeve 3 match the length and width of the dispensing tube 16. The dispensing tube 16 has first screw holes on both sides and second screw holes on both sides of the positioning sleeve 3. Hand-tightening bolts 6 are threaded into the corresponding first screw holes and second screw holes.

[0027] After unscrewing the hand-tightening bolts, the U-shaped frame adhesive can be removed, making it easy to replace.

[0028] In this embodiment, the side plate 9 is provided with a positioning hole 11, the inner diameter of which matches the diameter of the end of the hand-tightening bolt.

[0029] In this embodiment, the top surface of the rubber layer 10 is flush with the bottom surface of the U-shaped frame adhesive 14, and a sealing part 17 protrudes from the rubber layer 10, the length of the sealing part 17 matching the length of the adhesive outlet channel 15.

[0030] In this embodiment, an inlet pipe 7 is installed at the end of the glue dispensing shell 1 away from the glue outlet pipe 16. A hose is installed at one end of the inlet pipe, and an electric glue pump is installed at the other end of the hose. The electric glue pump can be placed in a container storing glue, and the glue can be injected into the glue dispensing shell through the hose and the inlet pipe.

[0031] In this embodiment, each fixing block 8 is provided with fixing holes 12, and screws can pass through the fixing holes to fix the placement seat on the work platform.

[0032] In this embodiment, a chamfer is provided on the opening on one side of the positioning channel 13, which facilitates the insertion of the support plate.

[0033] When using, the U-shaped frame adhesive is attached to the surface of the leather to be glued, and the side of the leather to be glued can be rested against the side, so that the glue injection shell can be accurately pushed along the side of the leather to be glued. After the glue enters the interior of the U-shaped frame adhesive through the glue outlet tube, the other three sides are sealed by the pressure between the U-shaped frame adhesive and the leather to be glued, so it can only be discharged through the glue outlet channel. The discharged glue is distributed in a line of equal width at the edge of the leather to be glued, to ensure the uniformity and continuity of the glue distribution.

[0034] After the adhesive is applied to the leather goods, the support plate is inserted into the positioning channel. The bottom surface of the U-shaped frame adhesive comes into contact with the rubber layer, thereby sealing the opening below the glue tube. The glue channel is inserted outside the sealing part, thus sealing the glue channel as well, avoiding waste caused by continuing to dispense glue.

[0035] As the injection shell moves onto the placement seat, a hand-tightening bolt on one side can be inserted into the positioning hole. The insertion between the hand-tightening bolt and the positioning hole can vertically position the injection shell, allowing the U-shaped frame adhesive to be pressed tightly against the rubber layer to ensure its sealing performance.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
