TECHNICAL FIELD
[0001] The application relates to the field of hot pressing equipment for recycled leather composite materials, in particular to a hot pressing composite machine for recycled leather composite materials. BACKGROUND
[0002] In the field of garment leather manufacturing, composite materials are widely used in various scenarios due to their excellent characteristics such as lightweight, high strength and multifunctionality. With the continuous growth of market demand, the hot pressing composite machine, as a key equipment for realizing the compounding of recycled leather and substrates (such as cloth, sponge, film, etc.), plays an important role in improving product quality and production efficiency.
[0003] At present, the hot pressing composite machine firmly combines recycled leather and substrates through heating and pressing. It mainly includes a machine frame, multiple hot pressing rollers and feeding rollers, a heating system for heating the hot pressing rollers, a hydraulic pressing system for driving the hot pressing rollers to press down, etc. In order to realize the compounding of recycled leather and substrates, the industry usually adopts the following means: setting a simple fixed baffle to preliminarily position the recycled leather and the substrate, or manually adjusting the relative position of the recycled leather and the substrate to prevent the width of the two from deviating. However, due to the softness of the substrate, the recycled leather and the substrate are still prone to deviation in the width direction when entering the hot pressing roller, especially for soft sponge substrates. The sponge substrate to be compounded on the side close to the hot pressing roller will be raised upward after extrusion, resulting in a decrease in the flatness of the compounded product and affecting the quality of the final product. CONTENT OF THE INVENTION

[0005] The hot pressing composite machine for recycled leather composite materials provided by the application adopts the following technical solution:
[0006] The hot pressing composite machine for recycled leather composite materials comprises a machine frame, a booster frame, a hot pressing roller rotatably connected to the booster frame for heating treatment of recycled leather, a heating system arranged between the hot pressing roller and the booster frame, a hydraulic system arranged on the machine frame for driving the booster frame to move up and down, a feeding roller rotatably connected to the machine frame and located directly below the hot pressing roller, a driving device arranged on the machine frame for driving the feeding roller to rotate, and multiple conveying rollers rotatably connected to one side of the machine frame for conveying substrates between the hot pressing roller and the feeding roller; further comprising
[0007] The adjusting mechanism is arranged between the frame and the conveying roller, and comprises a positioning assembly and an anti-edge-lifting assembly, wherein the positioning assembly is used for synchronous positioning of both sides in the width direction of the regenerated leather and both sides in the width direction of the base material; and the anti-edge-lifting assembly is used for limiting upward lifting of the base material to be compounded between the heat pressing roller and the feeding roller.
[0008] By adopting the technical scheme, when the regenerated leather and the base material are compounded by the heat pressing compound machine, the base material is first placed on the conveying roller, and the regenerated leather to be compounded is laid on the base material, then the driving device and the heating system are started, the feeding roller drives the base material and the regenerated leather to move forward, and the base material and the regenerated leather pass through the multiple heat pressing rollers and the feeding roller in sequence, wherein in the moving process, the positioning assembly synchronously and accurately positions both sides in the width direction of the regenerated leather and the base material, so as to ensure that the two are accurately aligned before entering the heat pressing area, and the anti-edge-lifting assembly limits upward lifting of the base material close to the heat pressing roller and the feeding roller, so as to ensure that the base material stably enters the heat pressing area, at the same time, the hydraulic system drives the pressure boosting frame to move up and down, so as to adjust the pressure between the heat pressing roller and the feeding roller, and the heating system heats the heat pressing roller, so that the regenerated leather reaches a suitable compounding temperature, finally, under the rotation of the feeding roller driven by the driving device, the heat pressing roller can complete the compounding process of the regenerated leather and the base material. The positioning assembly can accurately control the alignment state of the regenerated leather and the base material, and reduce the compounding quality problems caused by position deviation, and the anti-edge-lifting assembly ensures that the base material is flat when entering the heat pressing area, so as to solve the problems of position deviation of the regenerated leather and the base material and edge lifting of the base material in the compounding process of the heat pressing compound machine, and improve the compounding effect and the yield.
[0009] Optionally, the positioning assembly comprises:
[0010] The rotating shafts are coaxial and spaced apart.
[0011] The bidirectional screw is detachably connected between the two rotating shafts, and two adjusting sleeves are threadedly connected to the bidirectional screw, and the thread directions of the inner threads of the two adjusting sleeves are opposite.
[0012] The positioning plates are arranged in pairs and correspond to the two adjusting sleeves, and the regenerated leather and the base material are located between the two positioning plates and abut against the positioning plates.
[0013] The guide rods are fixed to the frame and penetrate the positioning plates and are in sliding connection with the positioning plates.
[0014] The connecting components are arranged between the bidirectional screw and the rotating shafts, and are used for connecting the bidirectional screw and the rotating shafts.
[0015] A correction mounting component is arranged between the positioning plate and the adjusting sleeve for connecting the positioning plate and the adjusting sleeve.
[0016] By using the above technical scheme, when the positioning assembly is used to position the recycled leather and the base material on both sides in the width direction, the bidirectional screw is first rotated by rotating the rotating shaft. Since the two adjusting sleeves with opposite thread directions are threadedly connected on the bidirectional screw, when the bidirectional screw rotates, the two adjusting sleeves move towards or away from each other. The movement of the adjusting sleeves drives the positioning plate to move synchronously through the correction mounting component, so as to adjust the distance between the two positioning plates, so that the recycled leather and the base material can be accurately positioned between the two positioning plates. At the same time, the guide rod penetrates the positioning plate and is in sliding connection with the positioning plate, so as to ensure that the positioning plate remains stable during movement and avoids deviation. In the positioning assembly, on the one hand, the adjusting sleeve can be accurately moved on the bidirectional screw, thereby driving the positioning plate to adjust the position and adapt to recycled leather and base materials of different widths. On the other hand, if there is a slight misalignment between the base material and the recycled leather, the composite material after compounding will be misaligned for a long distance, and the edges of the composite material will all become waste products, resulting in a large waste of material cost. Therefore, the positioning needs to be very accurate. If the adjusting sleeve is worn out after long-term use, the bidirectional screw needs to be disassembled through the connecting component, and a new adjusting sleeve needs to be replaced in time through the correction mounting component, so as to ensure the positioning accuracy, reduce material waste, and improve production efficiency.
[0017] Optionally, the connecting component comprises:
[0018] A connecting block is fixedly arranged on one end of the rotating shaft close to the bidirectional screw. The bidirectional screw is provided with a connecting groove at one end, and the connecting block is inserted into the connecting groove.
[0019] A connecting screw is arranged between the connecting block and the bidirectional screw. The connecting screw penetrates the connecting block and the bidirectional screw and is threadedly connected with a connecting nut.
[0020] By using the above technical scheme, the insertion and cooperation between the connecting block and the bidirectional screw can realize quick disassembly and assembly of the rotating shaft and the bidirectional screw. At the same time, the fastening effect of the connecting screw and the connecting nut ensures the connection stability between the rotating shaft and the bidirectional screw.
[0021] Optionally, the correction mounting component comprises:
[0022] A first positioning flange plate is fixedly arranged on one side of the adjusting sleeve and coaxially arranged with the adjusting sleeve.
[0023] Second positioning flanges, two are provided and are arranged in a half ring shape, the two second positioning flanges are symmetrically sleeved outside the bidirectional screw, and the first positioning flange and the second positioning flange are respectively abutted on both sides of the positioning plate.
[0024] Mounting bolts are provided between the first positioning flange and the second positioning flange, and a plurality of mounting bolts are provided, one end of the mounting bolt penetrates the first positioning flange and the second positioning flange at the same time and is threadedly connected with a mounting nut.
[0025] By adopting the above technical scheme, when the positioning plate is connected and installed with the adjusting sleeve through the correction mounting part, first, the adjusting sleeve is rotated, the adjusting sleeve drives the first positioning flange to move to abut on one side of the positioning plate, then the two second positioning flanges in a half ring shape are symmetrically sleeved outside the bidirectional screw, then a plurality of mounting bolts are simultaneously penetrated through the first positioning flange and the second positioning flange, and are fastened and connected through the mounting nut, so that the connection of the positioning plate and the adjusting sleeve is completed; wherein through the cooperation of the first positioning flange and the second positioning flange, the position of the positioning plate can be accurately corrected and fixed, the synchronous positioning accuracy of the two sides of the width direction of the regenerated leather and the base material is ensured, and the half ring-shaped second positioning flange is convenient to disassemble and assemble, the positioning plate can be adjusted without completely disassembling the bidirectional screw, and the convenience of equipment maintenance and debugging is improved.
[0026] Optionally, the first positioning flange is located on one side where the two positioning plates are away from each other, and two positioning sleeves are sleeved on the bidirectional screw at intervals, and the inner wall of the positioning sleeve is tightly attached to the outer side of the bidirectional screw and can slide axially along the bidirectional screw.
[0027] By adopting the above technical scheme, the positioning sleeve can limit the position of the adjusting sleeve on the bidirectional screw, and prevent the phenomenon that the adjusting sleeve is excessively adjusted axially and separated from the threaded part of the bidirectional screw during use.
[0028] Optionally, the anti-warping assembly comprises:
[0029] A support frame is fixedly arranged on the rack;
[0030] An adjusting rod is slidably connected to the support frame in the vertical direction;
[0031] An anti-warping plate is fixedly arranged below the adjusting rod, and the bottom of the anti-warping plate abuts against the top of the base material;
[0032] A locking part is arranged between the adjusting rod and the support frame, and is used for locking the position of the adjusting rod.
[0033] By adopting the above technical scheme, when the base material needs to be replaced, first, the anti-curling plate is driven to move upward by the adjusting rod, and the position of the adjusting rod is locked by the locking component, then the base material is placed on the conveying roller and the position is adjusted, then the locking of the adjusting rod by the locking component is released, the anti-curling plate naturally falls and abuts against the top of the base material, then the adjusting rod is fixed by the locking component, so that the anti-curling plate can continuously and stably act on the surface of the base material. The adjusting rod can be moved up and down according to the thickness of the base material, so as to adjust the height position of the anti-curling plate according to actual needs, so as to adapt to base materials of different thicknesses. The anti-curling plate is fixed below the adjusting rod, and the bottom thereof directly contacts the top of the base material. By applying a certain pressure, the upward curling of the base material is limited, so as to reduce the curling phenomenon of the base material when entering between the heat pressing roller and the feeding roller, and the flatness of the composite material is ensured.
[0034] Optionally, the locking component comprises:
[0035] A fixed lock seat is fixedly arranged on the support frame;
[0036] A movable lock seat is slidably connected to the support frame, and the fixed lock seat and the movable lock seat both abut against the outside of the adjusting rod;
[0037] A locking screw is threadedly connected to one end of the support frame and rotationally connected to the other end of the movable lock seat.
[0038] By adopting the above technical scheme, when the position of the anti-curling plate needs to be adjusted, the operator can rotate the locking screw. Since one end of the locking screw is threadedly connected to the support frame and the other end is rotationally connected to the movable lock seat, rotating the locking screw can drive the movable lock seat to slide along the support frame. At this time, the movable lock seat and the fixed lock seat jointly clamp or release the adjusting rod, so as to realize the fixation or release of the adjusting rod. The locking component has a simple structure and can quickly realize the locking and unlocking of the position of the adjusting rod, thereby improving the adjustment efficiency of the equipment.
[0039] In summary, the present application has at least one of the following beneficial technical effects:
[0040] 1. The positioning assembly can accurately control the alignment state of the regenerated leather and the base material, reduce the composite quality problems caused by position deviation, and the anti-curling assembly can keep the base material flat when entering the heat pressing area, thereby solving the problems of regenerated leather and base material positioning deviation and base material curling in the composite process of the heat pressing composite machine, and improving the composite effect and yield;
[0041] 2. In one aspect of the positioning assembly, the adjusting sleeve can be precisely moved on the bidirectional screw, thereby driving the positioning plate to adjust the position to adapt to different widths of the reclaimed leather and the base material; in another aspect, if a slight misalignment occurs between the base material and the reclaimed leather, the composite material after compounding will be misaligned continuously for a long distance, and the edges of the composite material will all become waste products, resulting in a large waste of material cost. Therefore, the positioning needs to be very precise. If the adjusting sleeve is worn out after long-term use, the bidirectional screw needs to be disassembled through the connecting part, and a new adjusting sleeve is replaced in time through the correction installation part, so as to ensure the positioning accuracy while reducing material waste and improving production efficiency;

DETAILED DESCRIPTION
[0050] The following will be described in detail below with reference to the accompanying drawings. Figures 1-5 The present application is further described in detail.
[0051] The inventor of the present application found that regenerated leather and base material are prone to deviation on both sides in the width direction when entering the hot-pressing roller, especially for soft sponge base material, the sponge base material to be compounded near the hot-pressing roller side will be warped upward after extrusion, resulting in a decrease in flatness of the regenerated leather and base material after compounding, affecting the quality of the final product. Therefore, the present application mainly uses an adjusting mechanism to synchronize the positioning of regenerated leather and base material, and limits the warping of the base material through an anti-warping assembly, so as to improve the flatness and quality of the compounded material.
[0052] The embodiment of the present application discloses a hot-pressing compounding machine for regenerated leather compounded material. Referring to Figure 1 and Figure 2 , the hot-pressing compounding machine comprises a rack 1, a booster frame 2, a hot-pressing roller 3, a heating system, a hydraulic system 4, a feeding roller 5, a driving device, a conveying roller 6 and an adjusting mechanism 7. The hot-pressing roller 3 is arranged in parallel and rotationally connected to the booster frame 2, and is used for heating treatment of regenerated leather 8. The heating system is arranged between the hot-pressing roller 3 and the booster frame 2, and is used for providing a heat source for the hot-pressing roller 3. The hydraulic system 4 is arranged on the rack 1 and is used for driving the booster frame 2 to move up and down. The feeding roller 5 is arranged in parallel and corresponds to the hot-pressing roller 3 one by one, the feeding roller 5 is rotationally connected to the rack 1 and located directly below the corresponding hot-pressing roller 3. The driving device is arranged on the rack 1 and is used for driving the feeding roller 5 to rotate. The conveying roller 6 is arranged in plurality and rotationally connected to one side of the rack 1, and is used for conveying base material 9 between the hot-pressing roller 3 and the feeding roller 5.
[0053] The adjusting mechanism 7 is arranged between the rack 1 and the conveying roller 6, and comprises a positioning assembly 71 and an anti-warping assembly 72. The positioning assembly 71 is used for synchronously positioning both sides of the recycled leather 8 and the base material 9 in the width direction. The anti-warping assembly 72 is used for limiting the upward warping of the base material 9 to be compounded between the heat pressing roller 3 and the feeding roller 5.
[0054] When the recycled leather 8 and the base material 9 are compounded by the heat pressing compound machine, the base material 9 is first placed on the conveying roller 6, and the recycled leather 8 to be compounded is laid on the base material 9. Then, the driving device and the heating system are started. The feeding roller 5 drives the base material 9 and the recycled leather 8 to move forward, so that the base material 9 and the recycled leather 8 pass through the multiple heat pressing rollers 3 and feeding rollers 5 in sequence. During the movement, the positioning assembly 71 synchronously and accurately positions both sides of the recycled leather 8 and the base material 9 in the width direction, so as to ensure that the two are accurately aligned before entering the heat pressing area. At the same time, the anti-warping assembly 72 limits the upward warping of the base material 9 between the heat pressing roller 3 and the feeding roller 5, so as to ensure that the base material 9 stably enters the heat pressing area. At the same time, the hydraulic system 4 drives the pressure boosting frame 2 to move up and down, so as to adjust the pressure between the heat pressing roller 3 and the feeding roller 5. The heating system heats the heat pressing roller 3, so that the recycled leather 8 reaches a suitable compounding temperature. Finally, under the rotation of the feeding roller 5 driven by the driving device, the heat pressing roller 3 can complete the compounding process of the recycled leather 8 and the base material 9.
[0055] Specifically, referring to Figure 3 and Figure 4 , the positioning assembly 71 comprises rotating shafts 711, bidirectional screws 712, adjusting sleeves 713, positioning plates 714, guide rods 715, connecting components 716 and correction mounting components 717. The rotating shafts 711 are arranged in two and rotationally connected to the rack 1. The two rotating shafts 711 are coaxial and arranged at intervals. One end of one of the rotating shafts 711 is fixedly provided with a hand wheel 718. The bidirectional screw 712 is detachably connected between the two rotating shafts 711. The adjusting sleeves 713 are arranged in two and threadedly sleeved outside the bidirectional screw 712. The internal threads of the two adjusting sleeves 713 are opposite in screw rotation direction. The positioning plates 714 are arranged in two and correspond to the two adjusting sleeves 713 one by one. The recycled leather 8 and the base material 9 are located between the two positioning plates 714 and abut against the positioning plates 714. The guide rod 715 is fixedly arranged on the rack 1, penetrates through the positioning plate 714 and is slidably connected thereto. The connecting component 716 is arranged between the bidirectional screw 712 and the rotating shaft 711, and is used for connecting the bidirectional screw 712 and the rotating shaft 711. The correction mounting component 717 is arranged between the positioning plate 714 and the adjusting sleeve 713, and is used for connecting the positioning plate 714 and the adjusting sleeve 713.
[0056] When the two sides of the recycled leather 8 and the base material 9 in the width direction are positioned synchronously by the positioning assembly 71, first, the hand wheel 718 is rotated to drive the rotating shaft 711 to rotate, and the rotating shaft 711 drives the bidirectional screw 712 to rotate. Since the bidirectional screw 712 is externally threaded connected with two adjusting sleeves 713 with opposite internal threads, when the bidirectional screw 712 rotates, the two adjusting sleeves 713 will move towards or away from each other. The movement of the adjusting sleeves 713 drives the positioning plates 714 to move synchronously through the correction mounting component 717, so as to adjust the distance between the two positioning plates 714, so that the recycled leather 8 and the base material 9 can be accurately positioned between the two positioning plates 714. The adjusting sleeves 713 can be accurately moved on the bidirectional screw 712, thereby driving the positioning plates 714 to adjust the position and adapt to recycled leather 8 and base material 9 of different widths. If there is a slight misalignment between the base material 9 and the recycled leather 8, it will cause misalignment of the composite material after compounding for a long distance, and the edges of the composite material will all become waste products, resulting in a large amount of material cost. Therefore, the positioning needs to be very accurate. If the adjusting sleeves 713 are worn out after a long time of use, the bidirectional screw 712 needs to be disassembled through the connecting component 716, and the new adjusting sleeves 713 need to be replaced in time through the correction mounting component 717, so as to ensure the positioning accuracy and reduce material waste.
[0057] Specifically, referring to Figure 3 and Figure 4 , the connecting component 716 includes a connecting block 7161 and a connecting screw 7162. The connecting block 7161 is fixedly arranged on one end of the rotating shaft 711 close to the bidirectional screw 712. The bidirectional screw 712 is provided with a connecting groove 7111 at one end, and the connecting block 7161 is inserted into the connecting groove 7111. The connecting screw 7162 is arranged between the connecting block 7161 and the bidirectional screw 712, penetrates the connecting block 7161 and the bidirectional screw 712 and is threadedly connected with a connecting nut 7163. The connecting block 7161 is made of metal material and has a cylindrical or square shape with high strength and wear resistance. The connecting screw 7162 is made of stainless steel and is subjected to heat treatment on the surface to improve wear resistance and corrosion resistance. The connecting mode between the connecting block 7161 and the bidirectional screw 712 can also be a buckle type connection, for example, a clamping groove is arranged on the connecting block 7161, and a clamping hook is arranged on the bidirectional screw 712, and the connection is realized through the cooperation of the clamping groove and the clamping hook.
[0058] Specifically, referring to Figure 3 and Figure 4The correction mounting component 717 includes a first positioning flange 7171, a second positioning flange 7172, and mounting bolts 7173. The first positioning flange 7171 is fixed to one side of the adjusting sleeve 713 and coaxially arranged with the adjusting sleeve 713, and is located on the side away from the two positioning plates 714. The second positioning flange 7172 is arranged in two halves and is arranged in a semi-ring shape. The two second positioning flanges 7172 are symmetrically arranged outside the bidirectional screw rod 712, and the first positioning flange 7171 and the second positioning flange 7172 abut the two sides of the positioning plate 714, respectively. The mounting bolts 7173 are arranged between the first positioning flange 7171 and the second positioning flange 7172 and are arranged in multiple. One end of the mounting bolt 7173 penetrates the first positioning flange 7171 and the second positioning flange 7172 at the same time and is threadedly connected with a mounting nut 7174. Two positioning sleeves 7175 are arranged on the bidirectional screw rod 712 in intervals. The inner wall of the positioning sleeve 7175 is tightly attached to the outer side of the bidirectional screw rod 712 and can slide axially along the bidirectional screw rod 712. The positioning sleeve 7175 can be made of flexible rubber material with good wear resistance. The shape of the positioning sleeve 7175 can be cylindrical, and the inner diameter matches the outer diameter of the bidirectional screw rod 712.
[0059] When the positioning plate 714 is connected and mounted with the adjusting sleeve 713 through the correction mounting component 717, first, the adjusting sleeve 713 is rotated to move the first positioning flange 7171 to abut the side of the positioning plate 714. Then, the two second positioning flanges 7172 in a semi-ring shape are symmetrically arranged outside the bidirectional screw rod 712. Subsequently, the ends of the multiple mounting bolts 7173 penetrate the first positioning flange 7171 and the second positioning flange 7172 at the same time, and are fastened and connected through the mounting nut 7174. Thus, the connection of the positioning plate 714 and the adjusting sleeve 713 is completed.
[0060] Specifically, referring to Figure 2 and Figure 5 The anti-warping assembly 72 includes a support frame 721, an adjusting rod 722, an anti-warping plate 723, and a locking component 724. The support frame 721 is fixed to the rack 1. The adjusting rod 722 is slidingly connected to the support frame 721 in the vertical direction. The anti-warping plate 723 is fixed below the adjusting rod 722, and the bottom of the anti-warping plate 723 abuts the top of the base material 9. The anti-warping plate 723 can be made of flexible materials, such as rubber or silicone, which have good elasticity and wear resistance. The locking component 724 is arranged between the adjusting rod 722 and the support frame 721 to lock the position of the adjusting rod 722.
[0061] When the base material 9 needs to be replaced, first, the anti-warping plate 723 is moved upward by adjusting the rod 722, and the adjusting rod 722 is locked by the locking part 724, then the base material 9 is placed on the conveying roller 6 and adjusted, then the locking of the adjusting rod 722 by the locking part 724 is released, the anti-warping plate 723 naturally falls and abuts against the top of the base material 9, then the adjusting rod 722 is fixed by the locking part 724, so that the anti-warping plate 723 can continuously and stably act on the surface of the base material 9. The adjusting rod 722 can be moved up and down according to the thickness of the base material 9, so as to adjust the height position of the anti-warping plate 723 according to actual needs, to adapt to base materials 9 of different thicknesses. The anti-warping plate 723 is fixed below the adjusting rod 722, and the bottom thereof directly abuts against the top of the base material 9, so as to limit the upward warping of the base material 9 by applying a certain pressure, thereby reducing the warping phenomenon of the base material 9 when entering between the hot-pressing roller 3 and the feeding roller 5, and ensuring the flatness of the composite material.
[0062] Specifically, referring to Figure 5 The locking part 724 includes a fixed lock seat 7241, a movable lock seat 7242, and a locking screw 7243. The fixed lock seat 7241 is fixedly arranged on the support frame 721. The movable lock seat 7242 is slidably connected to the support frame 721, and the fixed lock seat 7241 and the movable lock seat 7242 abut against the outside of the adjusting rod 722. The locking screw 7243 is threadedly connected to the support frame 721 at one end and rotatably connected to the movable lock seat 7242 at the other end. The cooperation between the movable lock seat 7242 and the support frame 721 can also adopt a dovetail groove structure, for example, a dovetail groove is arranged on the movable lock seat 7242, and a dovetail block matched with the dovetail groove is arranged on the movable lock seat 7242, and the sliding connection is realized by the cooperation of the dovetail groove and the dovetail block.
[0063] When the position of the anti-warping plate 723 needs to be adjusted, the operator can rotate the locking screw 7243. Since one end of the locking screw 7243 is threadedly connected to the support frame 721, and the other end is rotatably connected to the movable lock seat 7242, rotating the locking screw 7243 can drive the movable lock seat 7242 to slide along the support frame 721. At this time, the movable lock seat 7242 and the fixed lock seat 7241 jointly clamp or release the adjusting rod 722, so as to realize the fixation or release of the adjusting rod 722.
[0064] The implementation principle of the hot pressing compound machine for the regenerated leather composite material is as follows: when the regenerated leather 8 and the base material 9 are compounded by the hot pressing compound machine, first, the base material 9 is placed on the conveying roller 6, and the regenerated leather 8 to be compounded is laid on the base material 9, then the driving device and the heating system are started, the feeding roller 5 drives the base material 9 and the regenerated leather 8 to move forward, and the base material 9 and the regenerated leather 8 pass through multiple hot pressing rollers 3 and feeding rollers 5 in sequence, wherein during the movement process, the positioning assembly 71 synchronously and accurately positions the two sides of the regenerated leather 8 and the base material 9 in the width direction, ensures that the two are accurately aligned before entering the hot pressing area, and prevents the base material 9 near the hot pressing roller 3 and the feeding roller 5 from being raised upward by the anti-curling assembly 72, so as to ensure that the base material 9 stably enters the hot pressing area, at the same time, the hydraulic system 4 drives the pressure boosting frame 2 to move up and down, adjusts the pressure between the hot pressing roller 3 and the feeding roller 5, and the heating system heats the hot pressing roller 3, so that the regenerated leather 8 reaches a suitable compounding temperature, finally, under the rotation of the feeding roller 5 driven by the driving device, the hot pressing roller 3 can complete the compounding process of the regenerated leather 8 and the base material 9. The positioning assembly 71 can accurately control the alignment state of the regenerated leather 8 and the base material 9, reduce the compounding quality problems caused by position deviation, and the anti-curling assembly 72 can make the base material 9 keep flat when entering the hot pressing area, so as to solve the problems of positioning deviation of the regenerated leather 8 and the base material 9 and curling of the base material 9 in the compounding process of the hot pressing compound machine, and improve the compounding effect and the yield.
