Description

Technical Field

[0001] This invention relates to the field of leather goods and luggage manufacturing technology, and more specifically to a glue-spreading auxiliary mechanism, which relates to a glue-spreading auxiliary mechanism for bubble-forming in leather goods and luggage manufacturing. Background Technology

[0002] Leather bags and trunks refer to various bags and trunks made of leather. There are different types of leather bags and trunks, including wallets, backpacks, briefcases, and suitcases. Leather bags and trunks encompass traditional leather products as well as leather goods such as leather sofas, chairs, and beds. Leather bags and trunks are waterproof and durable. The production of leather bags and trunks requires bonding different layers of leather, which necessitates the use of adhesives. To improve the evenness of adhesive application, a foaming and evenly applying adhesive auxiliary mechanism is needed in leather bag and trunk production.

[0003] For example, Chinese Patent Publication No. CN117445528A discloses an auxiliary device for applying adhesive evenly in the production of leather goods and bags. This invention provides an auxiliary device for applying adhesive evenly in the production of leather goods and bags, utilizing flowable adhesive to bond leather. The device includes a work panel and a support frame. The work panel is mounted on the upper part of the support frame. It also includes a pressing mechanism and a dispensing mechanism. The work panel has a pressing mechanism for pressing and bonding two pieces of leather, and the pressing mechanism has a dispensing mechanism for spraying hot melt adhesive between the two pieces of leather. By moving the scraper to the right, the hot melt adhesive between the leather pieces can be evenly spread, preventing air bubbles and improving the quality of the bonded leather.

[0004] The existing technical solution involves moving a scraper to the right to spread the hot melt adhesive evenly between the leather pieces, avoiding air bubbles. However, in actual testing, this simple scraping motion was found to be insufficient in removing air bubbles from the adhesive. The adhesive was not evenly spread, and the remaining air bubbles could not be punctured and removed. As the adhesive dried, a large number of air bubbles remained inside, making the bonded leather prone to cracking and negatively impacting its lifespan and quality. Therefore, a new solution is needed to address this problem. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a glue-spreading auxiliary mechanism for bubble-forming in leather goods and bags production. This mechanism solves the problems of existing technologies, such as the inability to repeatedly and thoroughly spread the glue, the inability to puncture and remove air bubbles in the glue, resulting in a large number of residual air bubbles in the dried glue, and the inability to seal the glue outlet after use, leading to glue leakage.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an auxiliary mechanism for uniform glue application in the production of leather goods and bags, comprising a processing table and a defoaming component.

The telescopic end of the linear cylinder slides through the top of the processing table and the settling cylinder and is fixedly connected to the filter plate. The filter plate is located inside the settling cylinder. A puncture needle is fixedly installed on the bottom surface of the filter plate. A fixing tube is fixedly installed below the settling cylinder.

[0007] By adopting the above technical solution, when the adhesive is delivered from above into the settling cylinder, the adhesive can pass through the filter plate into the lower part of the settling cylinder. After the adhesive inside the settling cylinder is settling, the large air bubbles inside can rise and float on the surface of the adhesive inside the settling cylinder, below the puncture needle. By activating the linear cylinder, the filter plate can be driven to descend, and the filter plate can drive the puncture needle to descend. The puncture needle can initially puncture the large air bubbles on the surface of the adhesive inside the settling cylinder. The fixing tube can drive the settling cylinder to connect with the sleeve.

[0013] The present invention is further configured such that: a conveying component is installed on the processing table, the conveying component being used to move the leather goods.

[0014] The present invention is further configured such that: the conveying assembly includes a second servo motor, a drive shaft and a driven shaft, the output shaft of the second servo motor is fixedly connected to the drive shaft, and a conveyor belt is sleeved on the outside of the drive shaft and the driven shaft, the conveyor belt being located on the processing table and below the roller.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0027] like Figure 1-2 and Figure 5-6 As shown, an auxiliary mechanism for applying adhesive to create bubbles in leather goods and bags production includes a processing table 1 and a defoaming assembly 2. The defoaming assembly 2 is mounted on the processing table 1 and includes a linear cylinder 201, a settling cylinder 202, and a filter plate 203. The linear cylinder 201 can drive the filter plate 203 to rise and fall. The settling cylinder 202 can easily load adhesive. The filter plate 203 can support the piercing needle 204. The fixed end of the linear cylinder 201 is fixedly mounted on the top of the processing table 1. The settling cylinder 202... The linear cylinder 201 is fixedly connected to the top of the processing table 1. The telescopic end of the linear cylinder 201 slides through the processing table 1 and the top of the settling cylinder 202 and is fixedly connected to the filter plate 203. The filter plate 203 is located inside the settling cylinder 202. A piercing needle 204 is fixedly installed on the bottom surface of the filter plate 203. The piercing needle 204 can puncture the air bubbles in the adhesive inside the settling cylinder 202. A fixing tube 205 is fixedly installed at the bottom of the settling cylinder 202. The fixing tube 205 can conveniently deliver adhesive to the sleeve 301.

[0028] When the adhesive is fed into the settling cylinder 202 from above, the adhesive can pass through the filter plate 203 and enter the lower part of the settling cylinder 202. After the adhesive is settling, the large air bubbles inside the settling cylinder 202 can rise and float on the surface of the adhesive inside the settling cylinder 202 and below the puncture needle 204. By activating the linear cylinder 201, the filter plate 203 can be driven to descend, and the filter plate 203 can drive the puncture needle 204 to descend. The puncture needle 204 can initially puncture the large air bubbles on the surface of the adhesive inside the settling cylinder 202. The fixing tube 205 can drive the settling cylinder 202 to connect with the sleeve 301.

[0029] like Figure 1 , Figure 3 and Figure 5-6 As shown, a defoaming and spreading component 3 is installed below the settling cylinder 202. This component is used to spread the adhesive evenly on the leather. The defoaming and spreading component 3 includes a sleeve 301, a fixing box 302, a servo motor 303, a roller 304, and a piercing shaft 305. The sleeve 301 drives the fixing tube 205 to connect with the fixing box 302. The fixing box 302 conveniently collects the adhesive conveyed by the sleeve 301. The servo motor 303 drives the roller 304 to rotate, allowing it to spread the adhesive evenly on the leather. The piercing shaft 305 can puncture the adhesive on the leather. Small air bubbles are punctured. The sleeve 301 is slidably sleeved on the outside of the fixed tube 205. The fixed box 302 is fixedly installed below the sleeve 301. The servo motor 303 is fixedly installed on the outside of the fixed box 302 and its output shaft is fixedly connected to the roller 304. The roller 304 and the puncture shaft 305 are both rotatably installed in the fixed box 302. Rollers 306 are installed on both the roller 304 and the puncture shaft 305. The rollers 306 can support the belt 307. The belt 307 is sleeved on the outside of the rollers 306. The belt 307 can drive the rollers 306 on both sides to move together.

[0030] The adhesive in the fixed tube 205 enters the sleeve 301, and the adhesive inside the sleeve 301 enters the fixed box 302. The leather goods are laid flat on the conveyor belt 904 and located below the roller 304. The adhesive inside the fixed box 302 can drip onto the leather goods through the adhesive outlet 5. The conveyor belt 904 drives the leather goods to move below the roller 304. At the same time, the servo motor 303 is started to drive the roller 304 to rotate. The rotation of the roller 304 drives the roller 306 connected to the roller 304 to rotate. The rotation of the roller 306 connected to the roller 304 drives the belt 307 to rotate. The rotation drives the roller 306 connected to the puncture shaft 305 to rotate, and the rotation of the roller 306 connected to the puncture shaft 305 drives the puncture shaft 305 to rotate. When the leather goods move below the roller 304, they can drive the glue above to move. The glue on the leather goods rubs against the roller 304, and the roller 304 can spread the glue on the leather goods. The rotation of the puncture shaft 305 can puncture the small air bubbles in the glue on the leather goods, and the rotation of the roller 304 can more fully roll and spread the glue on the leather goods, and can spread the glue on the leather goods more evenly.

[0031] like Figure 1 , Figure 3 and 5 As shown, a sealing component 4 is installed on the fixed box 302. The sealing component 4 is used to seal the glue outlet hole. The bottom surface of the fixed box 302 has a glue outlet hole 5, which can facilitate the delivery of glue to the leather. The sealing component 4 includes a linear cylinder 401 and a pressure plate 402. The linear cylinder 401 can drive the pressure plate 402 to rise and fall. The pressure plate 402 can drive the sealing column 403 to rise and fall. The fixed end of the linear cylinder 401 is fixedly installed above the fixed box 302. The telescopic end of the linear cylinder 401 slides through the top of the fixed box 302 and is fixedly connected to the pressure plate 402. The pressure plate 402 is installed inside the fixed box 302. The bottom surface of the pressure plate 402 is fixedly installed with a sealing column 403. The sealing column 403 can block the glue outlet hole 5 and passes through the glue outlet hole 5.

[0032] When the adhesive inside the settling cylinder 202 needs to be settling, the linear cylinder 401 is activated to raise the pressure plate 402. The top of the pressure plate 402 seals the bottom of the sleeve 301, preventing the adhesive from entering the fixing box 302 and preventing air bubbles in the adhesive inside the fixing box 302 from rising into the settling cylinder 202. When the adhesive needs to be supplied to leather goods, the linear cylinder 401 lowers the pressure plate 402, which in turn moves the sealing column 403. As the adhesive descends, the sealing column 403 is positioned at the middle height of the fixed box 302. At this point, the adhesive in the sleeve 301 can drip onto the leather through the fixed box 302 and the adhesive outlet 5. After the adhesive is supplied, the pressure plate 402 is lowered by starting the linear cylinder 401. The pressure plate 402 lowers the sealing column 403, which can penetrate into the adhesive outlet 5 to seal it and prevent the adhesive inside the fixed box 302 from leaking out and being wasted.

[0033] like Figure 1-2 and Figure 5-6 As shown, a conveying pipe 6 is fixedly sleeved above the settling cylinder 202. The conveying pipe 6 can convey adhesive to the settling cylinder 202. A pump body 7 is fixedly installed below the conveying pipe 6. The pump body 7 can draw adhesive from inside the box 8 into the conveying pipe 6. A box 8 is installed outside the pump body 7. The box 8 can hold adhesive. The conveying pipe 6 passes through the top of the box 8.

[0034] By activating the pump body 7, the adhesive liquid inside the box body 8 is driven into the delivery pipe 6, and the adhesive liquid inside the delivery pipe 6 can enter the settling cylinder 202.

[0035] like Figure 1 and Figure 4-6 As shown, a conveying assembly 9 is installed on the processing table 1. The conveying assembly 9 is used to move the leather goods. The conveying assembly 9 includes a servo motor 901, a drive shaft 902, and a driven shaft 903. The servo motor 901 can drive the drive shaft 902 to rotate. The drive shaft 902 can drive the conveyor belt 904 to rotate. The driven shaft 903 can support the conveyor belt 904. The output shaft of the servo motor 901 is fixedly connected to the drive shaft 902. The conveyor belt 904 is sleeved on the outside of the drive shaft 902 and the driven shaft 903. The conveyor belt 904 can move the leather goods. The conveyor belt 904 is located on the processing table 1 and below the roller 304.

[0036] The leather goods are placed on the conveyor belt 904, below the rollers 304 and the piercing shaft 305. The servo motor 901 is started to drive the drive shaft 902 to rotate. The drive shaft 902 drives the conveyor belt 904 to rotate. The conveyor belt 904 drives the driven shaft 903 to rotate. The driven shaft 903 supports the conveyor belt 904. The conveyor belt 904 can rotate around the drive shaft 902 and the driven shaft 903. The conveyor belt 904 can move the leather goods above below the rollers 304 and the piercing shaft 305, which makes it convenient for the rollers 304 to apply adhesive to the leather goods.

[0037] like Figure 5 As shown, a linear cylinder 310 is fixedly installed on the side wall of the processing table 1. The linear cylinder 310 can drive the fixed box 302 to rise and fall. The telescopic end of the linear cylinder 310 slides through the side wall of the processing table 1 and is fixedly connected to the fixed box 302.

[0038] By activating the linear cylinder 310, the fixed box 302 is raised and lowered. The fixed box 302 can raise and lower the roller 304 and the piercing shaft 305, and can adjust the distance between the roller 304 and the piercing shaft 305 and the conveyor belt 904, which can be conveniently applied to leather goods of different thicknesses.

[0039] like Figure 1 and Figure 5-6 As shown, a bracket 11 is installed inside the conveyor belt 904. The bracket 11 can fix the servo motor 901 and support the drive shaft 902 and the driven shaft 903. At the same time, the bracket 11 can support the conveyor belt 904 and prevent the conveyor belt 904 from sinking. The servo motor 901 is fixedly installed on the side wall of the bracket 11, and the drive shaft 902 and the driven shaft 903 are rotatably installed on the bracket 11.
