[0032] The hot melt adhesive heating compounding machine also includes:

[0033] A pre-treatment mechanism 4, the top of which is fixedly connected to the inner wall of the machine 1 near the belt 3; a glue spreading mechanism 5, the outer wall of which is fixedly connected to the inner wall of the machine 1, and the glue spreading mechanism 5 is located above the belt 3;

[0034] During operation, the leather coil is placed on the feeding shaft 2, the non-woven fabric is hung above the pretreatment mechanism 4, and the non-woven fabric is blocked by the limiting roller 7. After the leather passes through the pretreatment mechanism 4, hot melt adhesive is smeared under the gluing mechanism 5, and then the non-woven fabric is bonded to the leather under the drive of the belt 3, and the non-woven fabric is bonded to the leather through the squeezing roller 8, and finally the composite material is wound up by the winding roller 6. The pretreatment mechanism 4 cleans the dust on the surface of the leather, and the gluing mechanism 5 scrapes the hot melt adhesive on the surface of the leather and scrapes off the excess hot melt adhesive.

[0035] The pretreatment mechanism 4 includes a fixed frame 401, the outer wall of the fixed frame 401 is fixedly connected to the inner wall of the machine 1 near the belt 3, the inner wall of the fixed frame 401 is fixedly connected to a flattening assembly 402, the flattening assembly 402 is externally connected to an air extractor, the bottom of the flattening assembly 402 is fixedly connected to a cleaning assembly 403, and the bottom of the flattening assembly 402 is rotatably connected to a water-absorbing roller 404 at a side away from the cleaning assembly 403;

[0036] When the leather is transferred to the vicinity of the glue discharging device 501, the cleaning component 403 first contacts the surface of the leather to clean the dust on the surface of the leather, and the flattening component 402 drives the airflow to dry the surface of the leather. The flattening component 402 keeps the surface of the leather flat, and then the moisture on the surface of the leather is absorbed by the water-absorbing roller 404, and then the leather is spread with glue through the glue discharging device 501, so that the leather is pre-cleaned before processing. Since the leather surface has textures or gaps, it is difficult for dust to be directly removed from the surface of the leather by sweeping. The method of wetting the leather surface to remove dust can clean up the dust accumulated in the gaps of the leather, and then the surface of the leather is wiped dry so that the dust and debris on the surface of the leather can be separated from the leather in time, so that the glue spreading mechanism 5 can be kept clean, and the excess hot melt adhesive can be clearer to reduce waste.

[0037] The glue spreading mechanism 5 includes a glue discharging device 501, the outer wall of the glue discharging device 501 is fixedly connected to the inner wall of the machine 1, the outer wall of the glue discharging mechanism 5 is symmetrically provided with connecting rods 502, the outer wall of the connecting rod 502 is provided with an auxiliary component 504, the inner wall of the auxiliary component 504 is sleeved with the outer wall of the connecting rod 502, the outer wall of the connecting rod 502 is rotatably connected to the outer wall of the glue discharging device 501, and the end of the connecting rod 502 away from the glue discharging device 501 is rotatably connected to a supporting roller 503, the gap between the supporting roller 503 and the auxiliary component 504 can be stuck, so that the gap height through which the leather passes is kept consistent, thereby ensuring that the thickness of the hot melt adhesive on the surface of the leather is consistent, the outer wall of the supporting roller 503 is in contact with the inner wall of the belt 3, and the outer wall of the auxiliary component 504 is fixedly connected with an adjusting plate 505, and the top of the adjusting plate 505 is slidably connected to the bottom of the glue discharging device 501.

[0038] After the leather passes through the bottom of the glue dispensing device, the hot melt glue is applied to the leather surface, and then the leather passes through the auxiliary component 504 to scrape the hot melt glue on the leather surface. Initially, the height of the auxiliary component 504 on the connecting rod 502 is adjusted to allow excess hot melt glue to remain inside the auxiliary component 504, and the glue output of the glue dispensing device 501 is controlled according to the amount of hot melt glue inside the auxiliary component 504, thereby adjusting and controlling the accumulation of hot melt glue on the leather surface, thereby reducing the amount of hot melt glue output, avoiding excessive hot melt glue on the leather surface resulting in waste of hot melt glue, and preventing excess hot melt glue from rubbing against the surface of the equipment, making it difficult to clean.

[0039] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of embodiment 1, the flattening component 402 includes a cylinder 4021, the outer wall of the cylinder 4021 is fixedly connected to the inner wall of the fixing frame 401, the outer wall of the cylinder 4021 is fixedly connected to an exhaust pipe 4022, the exhaust pipe 4022 is externally connected to an exhaust fan, the air flow is drawn in through the bottom of the cylinder 4021, enters the exhaust pipe 4022 to generate air flow on the leather surface, and strengthens the drying of the leather surface, the inner wall of the cylinder 4021 is rotatably connected to a turntable 4023 at one end away from the exhaust pipe 4022, and the turntable 4023 is close to the exhaust pipe 4022. One end is fixedly connected to a movable rod 4024, and the outer wall of the movable rod 4024 is evenly provided with a sleeve rod 4025. The inner wall of the sleeve rod 4025 is sleeved with the outer wall of the movable rod 4024, and the bottom of the sleeve rod 4025 is fixedly connected to a limiting rod 4026. The shape of the limiting rod 4026 fits the outer wall of the cylinder 4021. The limiting rod 4026 is made of flexible material, and the bottom of the limiting rod 4026 is symmetrically provided with a pressing sheet 4027. The top of the pressing sheet 4027 is fixedly connected to the bottom of the limiting rod 4026, and the top of the limiting rod 4026 is in contact with the outer wall of the cylinder 4021.

[0040] After the leather passes through the cleaning component 403, its surface may have a certain curvature, causing the leather to be uneven during transmission. At this time, the turntable 4023 drives the connecting rod 502 to rotate, so that the sleeve rod 4025 drives the limiting rod 4026 to move up and down on the connecting rod 502, so that the limiting rod 4026 presses the leather surface, so that the pressing plate 4027 fits with the top of the leather, and the bulging part of the leather is pressed downward, so that the surface of the leather can be quickly dried and adjusted before applying the glue to keep the leather surface dry and flat, so that the glue can be applied more evenly.

[0041] The cleaning component 403 includes a baffle 4031, the outer wall of which is fixedly connected to the bottom of the cylinder 4021, and two baffles 4031 are symmetrically arranged. The baffles 4031 limit the leather so that the leather can be transported horizontally on the belt 3. Rollers 4032 are evenly arranged on the opposite sides of the baffle 4031. The rollers 4032 are used to squeeze the leather. The outer wall of the roller 4032 is rotatably connected to the opposite side of the baffle 4031. The end of the baffle 4031 away from the water-absorbing roller 404 is fixedly connected to a mounting frame 4033, and the outer wall of the mounting frame 4033 is evenly arranged with cleaning wheels 4034. A layer of water-absorbing material is provided on the surface of the cleaning wheel 4034. Starting from the middle, the cleaning wheels 4034 on both sides rotate in opposite directions, so that the leather is subjected to friction on both sides. The outer wall of the cleaning wheel 4034 is rotatably connected to the bottom of the mounting frame 4033. The top of the mounting frame 4033 is rotatably connected to a moisturizing groove 4035. The shape of the moisturizing groove 4035 can hold water-absorbing materials such as sponges. Then a certain amount of water is added. The bottom of the moisturizing groove 4035 contacts the outer wall of the cleaning wheel 4034. There is a gap at the position where the moisturizing groove 4035 contacts the cleaning wheel 4034, which can keep the cleaning wheel 4034 moist.

[0042] After the leather just contacts the surface of the belt 3, the leather is driven by the belt 3 to contact the cleaning wheel 4034 on the edge of the belt 3. After the cleaning wheel 4034 is pressed on the leather, the wet cleaning wheel 4034 contacts the leather surface and cleans it, so that the dust on the leather surface is taken away by the cleaning wheel 4034. Then the leather is dried by the airflow driven by the flattening component 402, and then the excess water is sucked away by the water-absorbing roller 404, so that the surface of the leather remains clean before the glue is applied. Due to the material characteristics of the leather, the dust is not easy to be swept away, so the cleaning wheel 4034 cleans the dust on the leather surface while keeping it moist, and limits the leather to keep it horizontally transmitted on the belt 3, thereby maintaining stable transmission of the leather.

[0043] The auxiliary component 504 includes an adjusting block 5041, which can drive the distance between the cross plate 5042 and the belt 3 to adjust the distance between the leather and the bottom of the cross plate 5042, so as to fix the distance between the leather and the bottom of the cross plate 5042, thereby determining the thickness of the hot melt adhesive. The inner wall of the adjusting block 5041 is sleeved with the outer wall of the connecting rod 502, and a cross plate 5042 is arranged at one end of the adjusting block 5041 away from the connecting rod 502. The interior of the cross plate 5042 can be heated to keep the hot melt adhesive in a melted state. The bottom of the cross plate 5042 has a scraper function to scrape off the hot melt adhesive, so that the excess hot melt adhesive accumulates upward along the curvature of the cross plate 5042. The inner wall of the cross plate 5042 is snapped with the outer wall of the connecting block, and the cross plate 5042 is close to the adjusting plate 505. An elastic sheet 5043 is provided at one end, an adjusting rotating rod 5044 is rotatably connected to the inner wall of the cross plate 5042, a fixing rod 5045 is evenly provided at the bottom of the adjusting rotating rod 5044, the top of the fixing rod 5045 is rotatably connected to the outer wall of the adjusting rotating rod 5044, a blocking sheet 5048 is provided at the bottom of the fixing rod 5045, both ends of the blocking sheet 5048 are rotatably connected to the inner wall of the cross plate 5042, a spring 5046 is evenly provided at one end of the adjusting rotating rod 5044 away from the fixing rod 5045, the top of the spring 5046 is fixedly connected to the bottom of the adjusting rotating rod 5044, the bottom of the spring 5046 is fixedly connected to a connecting plate 5047, and the outer wall of the connecting plate 5047 is fixedly connected to the inner wall of the elastic sheet 5043.

[0044] After the hot melt adhesive on the leather is scraped off at the bottom of the cross plate 5042, the excess hot melt adhesive enters the interior of the cross plate 5042 along the curvature of the cross plate 5042, and gradually accumulates, causing the baffle 5048 to be squeezed and move upward, thereby driving the fixing rod 5045 to squeeze the baffle 5048 upward, causing the baffle 5048 to drive the adjusting rotating rod 5044 to rotate, causing the spring 5046 to be squeezed to produce an outward pushing force on the elastic sheet 5043 and get stuck, causing the elastic sheet 5043 to drive the connecting plate 5047 to block the bottom of the glue discharge mechanism, thereby reducing the amount of glue discharged. Subsequently, the adjusting rotating rod 5044 rotates to drive the baffle 5048 to scrape excess hot melt adhesive from the cross plate 5042, causing it to accumulate on the surface of the leather, thereby increasing the amount of glue on the leather surface, and allowing the excess hot melt adhesive to be quickly utilized, thereby avoiding waste caused by excessive accumulation that cannot be recycled.

[0045] The specific workflow is as follows:

[0046] During operation, the leather coil is placed on the feeding shaft 2, and the non-woven fabric is hung above the pretreatment mechanism 4. The non-woven fabric is blocked by the limiting roller 7. When the leather is transmitted to the vicinity of the glue discharge device 501, the cleaning component 403 first contacts the surface of the leather to clean the dust on the leather surface, and the flattening component 402 drives the air flow to dry the leather surface. The flattening component 402 keeps the leather surface flat, and then the moisture on the leather surface is sucked dry by the water absorption roller 404, and then the glue is applied by the glue discharge device 501, so that the leather is pre-cleaned before processing. Since the leather surface has textures or gaps, it is difficult for dust to be directly removed from the leather surface by sweeping. The dust accumulated in the gaps of the leather can be cleaned by wetting the leather surface to remove dust, and then the leather surface is Wipe dry so that the dust and debris on the leather surface can be removed from the leather in time. After the leather passes through the bottom of the glue dispensing device, apply hot melt glue on the leather surface. Then the leather passes through the auxiliary component 504 to scrape the hot melt glue on the leather surface. Initially, the auxiliary component 504 is adjusted to a height on the connecting rod 502 so that excess hot melt glue remains inside the auxiliary component 504, and the glue output of the glue dispensing device 501 is controlled according to the amount of hot melt glue inside the auxiliary component 504, thereby adjusting and controlling the accumulation amount of hot melt glue on the leather surface. Finally, the non-woven fabric is attached to the leather through the extrusion roller 8, and the composite material is finally rolled up by the winding roller 6. The pretreatment mechanism 4 cleans the dust on the leather surface, and the glue applying mechanism 5 scrapes the hot melt glue on the leather surface and scrapes off the excess hot melt glue.
