Description

Technical Field

[0001] The invention belongs to the technical field of leather processing, in particular to a flame compounding machine for compound leather. Background Art

[0002] Flame lamination is a post-processing process in the deep processing of fabrics. It relies on the viscosity generated by the burning of the sponge between the two materials to bond the two materials together to obtain a more functional material. It is generally composed of a conveyor belt and a flame spraying mechanism. First, the leather to be laminated is placed on the conveyor belt for transportation. When it is transported to the bottom of the flame spraying mechanism, the flame spraying mechanism processes the leather, and then it is transported away by the conveyor belt after processing.

[0003] When the flame laminating machine burns the composite leather, if the actual width of the leather is narrow, the flame range sprayed by the internal flame-throwing equipment will be too large, which will cause part of the flame not to act on the outer surface of the leather. This will not only easily disperse the firepower, but also waste energy. The heat from the burning flame will cause the internal temperature of the equipment to rise sharply, and the inner shell will easily deform due to heat, so improvements are needed.

[0005] The heating device includes a long inner shell, a flame-throwing component is fixedly connected to the top of the inner wall of the long inner shell, and a spray hole plate is fixedly connected to the bottom of the flame-throwing component. The flame-throwing component sprays fire and heats the quilted leather in the middle through the spray hole plate at the bottom to melt the internal cotton layer. Fixed connecting rods are evenly fixed on the upper surface of the flame-throwing component. Closing components are symmetrically arranged on the front and rear sides of the inner wall of the long inner shell, and side sweeping plates are symmetrically arranged on the left and right sides of the outer surface of the long inner shell. Docking searchlights are evenly arranged on the bottom of the side sweeping plates. The docking searchlights of the side sweeping plates on the upper and lower sides are docked one by one, and a light curtain is formed by emitting light.

The inner cavity of the side sweeping plate drives the plug-in connecting plate to slide through the engaged rollers.

[0007] Furthermore, the outer surface of the plug-in connecting plate is meshed with the inner cavity of the side sweeping plate, the front end of the closed plug plate extends to the inside of the long inner shell through the through groove, and the outer surface of the closed plug plate is slidably connected to the middle of the inner wall of the long inner shell, and the top of the flame-spraying component is fixedly connected to the inner wall of the heat-insulating box shell through a fixed connecting rod. The number of the heating devices is two, the number of the side sweeping plates is four, the outer surface of the side sweeping plate is fixedly connected to the inner wall of the long inner shell, the upper surface of the closed plug plate is slidably connected to the lower surface of the orifice plate, and the flame-spraying port of the flame-spraying component is fixedly connected to the inner cavity of the orifice plate.

[0008] Furthermore, the side push device includes a side push plate, both ends of which are fixedly connected to an extension slide plate, and the side push plate and the extension slide plate are placed vertically to prevent the quilted leather from being deflected during the sliding process. The upper and lower ends of the extension slide plate are rollingly connected to the wall-attached rollers, and the two sides of the outer surface of the side push plate are symmetrically provided with segmented push rods, and the end of the segmented push rod away from the side push plate is fixedly connected to a fixed propeller. There are two fixed propellers, and the outer surface of the fixed propeller is fixedly connected to the inner wall of the heat-insulating box shell, the outer surface of the wall-attached roller is rollingly connected to the inner wall of the heat-insulating box shell, and the outer surface of the side push plate and the side surface of the outer surface of the quilted leather are pressed against each other.

[0009] Furthermore, a side of the extension slide away from the side push plate is fixedly connected to a drain, and the drain can perform jet operation. Both sides of the inner wall of the drain opening are rotatably connected to a hollow long tube, and the inner cavity of the hollow long tube is rotatably connected to an inner rotating through tube. An outer rotating roller is provided on the side of the outer surface of the hollow long tube close to the drain, and the axis of the outer rotating roller is rotatably connected to an independent motor through a connecting rod.

[0010] Furthermore, a long groove is provided at the bottom of the inner cavity of the hollow long tube, through openings are evenly provided at the bottom of the inner cavity of the inner rotating tube, the outer surface of the outer rotating roller is rollingly connected to the outer surface of the inner rotating tube through the groove, and the outer surface of the outer rotating roller is rotationally connected to the outer surface of the hollow long tube. The outer surface of the independent motor is fixedly connected to the outer surface of the extension slide, the outer surface of the diverter opening is rotationally connected to the inner cavity of the extension slide through the plug interface, the outer surface of the diverter housing is fixedly connected to the outer surface of the extension slide, and a groove for connecting the outer rotating roller is provided on the side of the hollow long tube, and the outer rotating roller can directly control the inner rotating tube to rotate, and when the through opening of the inner rotating tube is docked with the long groove of the hollow long tube, the diverter can perform jetting work outward normally.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The device can perform double-sided burning on the quilted leather to melt the sponge in the inner interlayer and bond the leather on both sides together. Since the flame-spraying component sprays flames on the passing quilted leather through the spray hole plate, and the actual flame-spraying range can be adjusted by the side sweeping plates on both sides, the width of the flame-spraying is ensured to be the same as the actual width of the quilted leather, avoiding the problem that the flame-spraying range of the flame-spraying component is too large, resulting in the dispersion of the firepower of the flame-spraying component and easy waste of energy.

[0013] 2. Since the flame-throwing component can adjust the flame-throwing distance through the closed plug plate, the flame-throwing component will definitely not spray flames on the side parts of the quilted leather, avoiding the phenomenon that the side parts of the quilted leather are easily burnt due to burning problems. When the closed plug plates on the front and rear sides are sliding, the distance between them will be more sensitively adjusted through the rangefinder at the bottom, thereby ensuring that the nozzle plate will not be completely blocked, avoiding the problem that the flame-throwing component cannot spray flames.

[0014] 3. After the quilted leather is burned, low-temperature air can be sprayed through the right-side drain for cooling. On the one hand, it can cool the quilted leather to prevent the burned quilted leather from sliding out of the device at a high temperature, which may cause injury. On the other hand, it can cool the inside of the insulation box shell to avoid thermal deformation of the insulation box shell. Although the drain on the left side can also perform air blowing, it is mainly used to clean dust and impurities on the outer surface of the quilted leather to prevent the quilted leather from being mixed with impurities during burning and then adhering to the outer surface of the quilted leather, affecting its appearance.

[0015] 4. When cooling is not in progress, in order to prevent the toxic smoke generated by the burning of the quilted leather from reversely penetrating into the interior of the drain through the through-hole, causing impurities such as smoke oil to appear inside the drain, the independent motor located on the side can rotate the inner rotating tube relative to the hollow long tube by twisting the outer rotating roller, so that the through-hole and the bottom groove of the hollow long tube are staggered. At this time, the hollow long tube is in a blocked state, thereby preventing the internal smoke from flowing back into the interior of the drain, ensuring the purity of the interior of the drain, and allowing the drain to perform normal blowing work.

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0025] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a composite leather flame laminating machine, comprising a protective component 1, the protective component 1 comprises a heat-insulating box shell 11, a built-in air suction machine 12 is symmetrically arranged on the left and right sides of the inner wall of the heat-insulating box shell 11, a twister 13 is symmetrically arranged on the upper and lower sides of the inner wall of the heat-insulating box shell 11, the outer surface of the output shaft of the twister 13 is rotatably connected with an active roller 14, the outer surface of the active roller 14 is rollingly connected with a quilted leather 4, the twister 13 can make the active rollers 14 on the upper and lower sides clamp the quilted leather 4 by rotating the power arm, and then the quilted leather 4 is transported from left to right, the front and rear sides of the inner wall of the heat-insulating box shell 11 are symmetrically arranged with side push devices 3, and the middle part of the inner wall of the heat-insulating box shell 11 is provided with a heating device 2;

[0026] The heating device 2 includes a long inner shell 21, and a flame-throwing component 22 is fixedly connected to the top of the inner wall of the long inner shell 21, and a spray hole plate 24 is fixedly connected to the bottom of the flame-throwing component 22. The flame-throwing component 22 performs flame-throwing heating on the quilted leather 4 in the middle through the spray hole plate 24 at the bottom to melt the internal cotton layer. A fixed connecting rod 23 is evenly fixed on the upper surface of the flame-throwing component 22, and a closing component 27 is symmetrically arranged on the front and rear sides of the inner wall of the long inner shell 21. Side sweeping plates 25 are symmetrically arranged on the left and right sides of the outer surface of the long inner shell 21. The bottom of the side sweeping plates 25 is evenly arranged with docking searchlights 26. The docking searchlights 26 of the side sweeping plates 25 on the upper and lower sides are docked one by one, and a light curtain is formed by emitting light. When the quilted leather 4 passes by, the light curtain will be separated, thereby obtaining the width data of the quilted leather 4.

[0027] The closing component 27 includes a closing plug plate 271, the inner cavity of the closing plug plate 271 is filled with a flame-retardant inner plate 272, a rangefinder 273 is fixedly connected to the front of the lower surface of the side sweeping plate 25, and plug-in connecting plates 274 are symmetrically arranged on the left and right sides of the outer surface of the side sweeping plate 25, and tooth grooves 275 are evenly opened on the upper surface of the plug-in connecting plate 274. The inner cavity of the side sweeping plate 25 drives the plug-in connecting plate 274 to slide through the engaged rollers.

[0028] The outer surface of the plug-in connecting plate 274 is meshed with the inner cavity of the side sweeping plate 25, the front end of the closed plug plate 271 extends to the inside of the long inner shell 21 through the through groove, and the outer surface of the closed plug plate 271 is slidably connected to the middle of the inner wall of the long inner shell 21, and the top of the flame-spraying component 22 is fixedly connected to the inner wall of the heat-insulating box shell 11 through the fixed connecting rod 23. There are two heating devices 2, and four side sweeping plates 25. The outer surface of the side sweeping plate 25 is fixedly connected to the inner wall of the long inner shell 21, the upper surface of the closed plug plate 271 is slidably connected to the lower surface of the orifice plate 24, and the flame-spraying port of the flame-spraying component 22 is fixedly connected to the inner cavity of the orifice plate 24.

[0029] Use this device to burn composite leather, sandwich a layer of sponge between the leathers, such as Figure 1 As shown, the quilted leather 4 is inserted into the interior of the heat-insulating box shell 11, the active roller 14 is rotated by the twister 13, the distance between the active rollers 14 is adjusted according to the actual thickness of the quilted leather 4, and then the active roller 14 rotates to transfer the quilted leather 4 from left to right.

[0030] When the quilted leather 4 is transported internally, it will be burned by the flame-spraying components 22 on the upper and lower sides when passing through the middle area. At this time, the flame is vertically sprayed to the outer surface of the leather through the spray hole plate 24. Since heating devices 2 are provided on the upper and lower sides, the sponge inside the leather is heated more evenly, and then the internal sponge material melts to bond the upper and lower layers of leather together.

[0031] When the leather is transported from left to right, the side scanning plates 25 located on the left and right sides of the long inner shell 21 will scan the actual width of the current quilted leather 4 through the vertical leather docking searchlight 26. When the width of the quilted leather 4 is narrow, the flame spraying range of the flame-spraying component 22 is larger, so the side scanning plates 25 will adjust the distance of the plug-in connecting plates 274 according to the actual size of the quilted leather 4 scanned by the light curtain, so that the plug-in connecting plates 274 drive the middle closed plug plate 271 to slide along the inner wall of the long inner shell 21, thereby shielding the area corresponding to the orifice plate 24. At this time, the flame-spraying component 22 can only spray downward through the open area in the middle of the orifice plate 24. Due to the adjustment, the actual flame spraying range of the heating equipment 2 is the same as the actual width of the quilted leather 4 passing through.

[0032] When adjusting the closed plug plate 271, since there is a rangefinder 273 at the bottom of the closed plug plate 271, the closed plug plate 271 will not be completely docked, resulting in complete blocking of the nozzle plate 24, making it impossible for the flamethrower 22 to perform the flamethrower operation, and the interior of the closed plug plate 271 is filled with a flame-retardant inner plate 272, so the closed plug plate 271 has good thermal insulation performance and extremely high heat resistance, and will not burn. The melting of the sponge inside the quilted leather 4 will produce toxic gases, but built-in suction machines 12 are provided at the openings on both sides of the insulation box shell 11 to avoid the problem of toxic gases diffusing to the outside.

[0033] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: on the basis of embodiment 1, the side push device 3 includes a side push plate 31, both ends of the side push plate 31 are fixedly connected with an extension slide plate 34, the side push plate 31 and the extension slide plate 34 are both placed vertically to prevent the quilted leather 4 from being deflected during the sliding process, the upper and lower ends of the extension slide plate 34 are rollingly connected with wall-attached rollers 35, the two sides of the outer surface of the side push plate 31 are symmetrically provided with segmented push rods 32, and the end of the segmented push rod 32 away from the side push plate 31 is fixedly connected with a fixed propeller 33. There are two fixed propellers 33, the outer surface of the fixed propeller 33 is fixedly connected to the inner wall of the heat-insulating box shell 11, the outer surface of the wall-attached roller 35 is rollingly connected to the inner wall of the heat-insulating box shell 11, and the outer surface of the side push plate 31 and the side of the outer surface of the quilted leather 4 are pressed against each other.

[0034] The side of the extension slide 34 away from the side push plate 31 is fixedly connected with a drain 36, and the drain 36 can perform jet operation. Both sides of the inner wall of the opening of the drain 36 are rotatably connected with a hollow long tube 39, and the inner cavity of the hollow long tube 39 is rotatably connected with an inner rotating tube 310. An outer rotating roller 38 is provided on the side of the outer surface of the hollow long tube 39 close to the drain 36, and the axis of the outer rotating roller 38 is rotatably connected to an independent motor 37 through a connecting rod.

[0035] The bottom of the inner cavity of the hollow long tube 39 is provided with a long groove, and the bottom of the inner cavity of the inner rotating tube 310 is evenly provided with through openings 311. The outer surface of the outer rotating roller 38 is rollingly connected to the outer surface of the inner rotating tube 310 through the groove, and the outer surface of the outer rotating roller 38 is rotationally connected to the outer surface of the hollow long tube 39. The outer surface of the independent motor 37 is fixedly connected to the outer surface of the extension slide 34, and the outer surface of the opening of the diverter 36 is rotationally connected to the inner cavity of the extension slide 34 through the plug interface. The outer surface of the housing of the diverter 36 is fixedly connected to the outer surface of the extension slide 34. A groove for connecting the outer rotating roller 38 is provided on the side of the hollow long tube 39. The outer rotating roller 38 can directly control the inner rotating tube 310 to rotate. When the through opening 311 of the inner rotating tube 310 is docked with the long groove of the hollow long tube 39, the diverter 36 can normally perform jetting work outward.

[0036] During the transportation of the quilted leather 4, the fixed pushers 33 on both sides will push the side push plates 31 through the segmented push rods 32, so that the side push plates 31 on both sides move toward the area that fits the sides of the quilted leather 4, thereby limiting the position of the quilted leather 4 to prevent the quilted leather 4 from being skewed when moving.

[0037] The quilted leather 4 is burned, and the internal sponge will melt. After passing through the heating device 2, the right-side drain 36 will be used for cooling, that is, the drain 36 uses the hollow long tube 39 to blow air to the outer surface close to the quilted leather 4 to cool it. In order to ensure the cooling effect, low-temperature gas needs to be introduced into the drain 36. The drain 36 twists the hollow long tube 39 to reciprocate and deflect to ensure that the range of the air jet is large enough, so that the quilted leather 4 can be effectively cooled during transportation. Although the drain 36 on the left side can also perform blowing work, it is mainly used to clean the dust and impurities on the outer surface of the quilted leather 4 to prevent the quilted leather 4 from being mixed with impurities during burning.

[0038] When cooling is not performed, in order to prevent the toxic smoke generated by the burning of the quilted leather 4 from reversely penetrating into the interior of the drain 36 through the through-hole 311, causing impurities such as smoke oil to appear inside the drain 36, the independent motor 37 located on the side can rotate the inner rotating tube 310 relative to the hollow long tube 39 by twisting the outer rotating roller 38, so that the through-hole 311 and the bottom groove of the hollow long tube 39 are offset. At this time, the hollow long tube 39 is in a blocked state, thereby preventing the internal smoke from flowing back into the interior of the drain 36, thereby ensuring the purity of the interior of the drain 36.

[0039] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
