Description

Technical Field

[0001] This invention relates to the field of leather waxing technology, specifically a leather waxing machine. Background Technology

[0002] Leather is a commonly used material in bags. Sewing or gluing leather to the surface of bags improves the feel of the bag surface and also enhances its protection. Leather waxing is an important step in leather processing.

[0003] Existing leather waxing machines have the following shortcomings:

[0004] Existing brushes have a large gliding stroke when applying wax, which results in insufficient and incomplete wax application, leading to uneven waxing and reduced waxing effect.

[0005] After waxing, the wax inside the drip hole will continue to move downwards, causing wax to accumulate at the tip of the drip hole. Once the wax at the tip of the drip hole solidifies, it will cause blockage of the drip hole. At the same time, the exposed drips are easily contaminated by dust, affecting the waxing effect.

[0006] To address the above issues, a leather waxing machine is now provided. Summary of the Invention

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. The present invention provides a leather waxing machine, which, by setting up an application mechanism, allows two brushes to move under the action of a moving component to apply wax to the entire surface of the leather. At the same time, with the cooperation of a reciprocating sliding component, the two brushes can also perform small-amplitude reciprocating sliding to apply the wax to the leather in a fine and small-amplitude manner. Thus, under the coordinated movement of the moving component and the reciprocating sliding component, the two brushes can brush the entire surface of the leather in a small-amplitude manner, avoiding any omissions in the application, which helps to improve the uniformity of waxing and enhance the waxing effect.

[0033] 2. The leather waxing machine of the present invention, by setting a conveying component and multiple drip holes, the multiple drip holes move with the movement of the moving plate, that is, the wax flowing onto the leather can be brushed immediately, which can achieve the effect of feeding and coating evenly at the same time, avoiding the drawback of waxing first and then brushing in the prior art, which is prone to causing the wax to solidify, and further improving the uniformity of leather waxing.

[0034] 3. The leather waxing machine of the present invention has two scrapers. After the waxing of a piece of leather is completed, the adjusting mechanism drives the lifting plate and drip holes to move upward. At this time, the two scrapers can move closer to each other. On the one hand, they can scrape off the excess oil and wax at the end of the drip holes to prevent solidification and blockage of the drip holes, which would affect normal use. On the other hand, they can seal the ports of multiple drip holes to prevent dust or other substances from entering and contaminating the oil and wax inside the drip holes, which would affect the waxing effect of the leather.

[0035] 4. The leather waxing machine of the present invention, by setting a transmission component, when a piece of leather is waxed, as the moving plate moves upward, the two scrapers move closer to each other under the action of the transmission component and the telescopic component, thereby sealing and cleaning the bottom of the drip hole. When the next piece of leather needs to be waxed, as the moving plate moves downward, the two scrapers move further apart under the action of the transmission component and the telescopic component, so that the bottom of the drip hole is unobstructed, and the wax can be dispensed normally. That is, under the action of the transmission component, the lifting movement of the moving plate and the horizontal movement of the two scrapers can be matched and connected, with a high degree of matching, which meets the usage requirements.

[0036] 5. The leather waxing machine of the present invention enables the adjustment mechanism and the cleaning mechanism to achieve a linkage effect through the rotating component, that is, the synchronous operation between the two mechanisms can be achieved by using a single drive source, which helps to reduce the number of drive sources used in the waxing machine, reduce power consumption, and thus help to reduce costs.

[0037] 6. The leather waxing machine of the present invention, by setting a positioning mechanism, can position and fix the leather located above the conveyor, so as to avoid the leather from wrinkling due to the action of the brush bristles during waxing, which is conducive to improving the waxing effect of the leather.

[0049] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0050] The present invention provides the following preferred embodiments:

[0051] Example 1, as Figures 1-10 As shown, a leather waxing machine includes a conveyor 11, a lifting plate 16, a moving plate 19, a waxing mechanism, an application mechanism, a cleaning mechanism, an adjustment mechanism, and a positioning mechanism. The lifting plate 16 is raised and lowered at the top of the conveyor 11 via the adjustment mechanism, which is used to adjust the height of the lifting plate 16. A guide rail 35 is fixed at the bottom of the lifting plate 16, and two sliding rods 36 are slidably arranged inside the guide rail 35. The bottom ends of the two sliding rods 36 are fixedly connected to the top of the moving plate 19. The guide rail 35 and the sliding rods 36 can not only drive the moving plate 19 to rise and fall when the lifting plate 16 rises and falls, but also will not affect the movement of the moving plate 19 below the lifting plate 16.

[0052] The waxing mechanism includes a conveying component and multiple drip holes 21. The multiple drip holes 21 are equidistantly installed at the bottom center of the moving plate 19. Specifically, the multiple drip holes 21 are installed in a straight line at the bottom of the moving plate 19. The conveying component is installed at the top of the lifting plate 16. The output end of the conveying component is connected to the multiple drip holes 21. When waxing is required, the conveying component can convey the wax to the multiple drip holes 21 and spray it onto the leather through the drip holes 21 to achieve the application of oil wax.

[0053] The application mechanism includes a sliding block 28, a moving component, a reciprocating sliding component, and two brush bristles 20. The two brush bristles 20 are symmetrically arranged at the bottom of the moving plate 19 and on both sides of the multiple drip holes 21. The sliding block 28 is slidably disposed on the lifting plate 16. The moving component is located between the sliding block 28 and the lifting plate 16. The moving component is used to drive the sliding block 28 to move above the lifting plate 16, thereby driving the moving plate 19 to move. The reciprocating sliding component is installed between the bottom of the sliding block 28 and the top of the moving plate 19. The reciprocating sliding component is used to drive the moving plate 19 to achieve small-amplitude reciprocating movement.

[0054] By setting up an application mechanism, the two brush bristles 20 can move under the action of the moving component to apply the coating to the entire leather surface. At the same time, with the cooperation of the reciprocating sliding component, the two brush bristles 20 can also perform small-amplitude reciprocating sliding to apply the oil and wax on the leather in a fine and small-amplitude manner. Thus, under the coordinated movement of the moving component and the reciprocating sliding component, the two brush bristles 20 can brush the entire leather surface in a small-amplitude manner, avoiding any omissions in the application, which helps to improve the uniformity of the oil and wax application and improve the waxing effect.

[0055] The cleaning mechanism includes two scrapers 39, two telescopic components and two transmission components. The two scrapers 39 are symmetrically arranged on both sides of the bottom end of multiple drip holes 21. Each telescopic component is located between one end of the two scrapers 39. Each transmission component is located between the moving plate 19 and a telescopic component. It should be noted that in the initial state, the two scrapers 39 are close to each other and press against each other to block the ports of the drip holes 21.

[0056] By setting two scrapers 39, after a piece of leather is waxed, the adjusting mechanism drives the lifting plate 16 and the drip hole 21 to move upward. At this time, the two scrapers 39 can approach each other. On the one hand, they can scrape off the excess oil and wax at the end of the drip hole 21 to prevent solidification and blockage of the drip hole 21, which would affect normal use. On the other hand, they can seal the ports of multiple drip holes 21 to prevent dust or other substances from entering and contaminating the oil and wax inside the drip hole 21, thus affecting the waxing effect of the leather.

[0057] The positioning mechanism includes two pressure plates 12 and two lifting components. The two lifting components are symmetrically installed on both sides of the conveyor 11. Each pressure plate 12 is fixed to the output end of a lifting component. Specifically, each pressure plate 12 is located above the conveyor belt in the conveyor 11 to facilitate the subsequent positioning of the leather on the conveyor belt. The lifting components can drive the pressure plates 12 to move, so that the pressure plates 12 can move above the leather and achieve pressing and fixing of the leather, avoiding wrinkles caused by the action of the brush bristles 20 during waxing, which is beneficial to improving the waxing effect of the leather.

[0058] like Figures 1-10As shown, the moving assembly includes a lead screw 29, a motor 31, and two mounting plates 30;

[0059] The top of the lifting plate 16 has two strip grooves 27. The bottom end of the sliding block 28 is inserted into the two strip grooves 27 and is slidably connected with the strip grooves 27. Two mounting plates 30 are symmetrically installed on both sides of the top of the lifting plate 16. The two ends of the screw 29 are rotatably connected to the two mounting plates 30 respectively. The sliding block 28 is sleeved on the screw 29. The sliding block 28 and the screw 29 are threaded together. The motor 31 is installed at one end of the lifting plate 16. The output end of the motor 31 is fixedly connected to one end of the screw 29.

[0060] When in use, when it is necessary to move the sliding block 28, the control motor 31 is activated. The motor 31 can drive the lead screw 29 to rotate. Since the lead screw 29 and the sliding block 28 are threadedly engaged, and the sliding block 28 and the strip groove 27 are slidably connected, when the lead screw 29 rotates, it can drive the sliding block 28 to slide inside the strip groove 27, thereby realizing the movement of the sliding block 28.

[0061] like Figures 1-10 As shown, the reciprocating sliding assembly includes a rotating rod 32, a first gear 33, a first rack 34, a turntable 37, and a first hinge rod 38;

[0062] The rotating rod 32 is rotatably mounted at the bottom end of the sliding block 28 via a bearing. The two ends of the rotating rod 32 are fixedly connected to the turntable 37 and the first gear 33, respectively. The rotating rod 32, the turntable 37, and the first gear 33 are coaxially arranged. The first rack 34 is fixedly installed at the bottom end of the lifting plate 16. The first gear 33 and the first rack 34 mesh with each other. One end of the first hinge rod 38 is hinged to the top end of the moving plate 19, and the other end of the first hinge rod 38 is hinged to the surface edge of the turntable 37.

[0063] When the sliding block 28 moves along the length of the groove 27, it drives the rotating rod 32 to move. At this time, the first gear 33 moves with the rotating rod 32. Since the first gear 33 and the first rack 34 mesh, the first gear 33 can rotate around the axis of the rotating rod 32 when it moves, so that the first gear 33 moves and rotates at the same time. When the first gear 33 rotates, it drives the turntable 37 to rotate through the rotating rod 32. Under the action of the first hinge rod 38, the moving plate 19 can achieve a small-amplitude reciprocating motion. At the same time, since the sliding block 28 can move linearly along the groove 27, the lead screw 29 can move along the length of the groove 27 while performing a small-amplitude reciprocating motion. This allows the two bristles 20 to brush the entire surface of the leather in a small amplitude, avoiding any missed areas and improving the uniformity of the wax application and the waxing effect.

[0064] like Figures 1-10As shown, each transmission component includes a movable frame 52, a sliding seat 53, a second rack 45, a second gear 46, a third rack 48, and a third gear 49;

[0065] The movable frame 52 is located at one end of the movable plate 19. The second gear 46 and the third gear 49 are coaxially arranged and rotatably mounted on the movable frame 52, and can rotate synchronously. The second rack 45 is located on one side of the second gear 46 and meshes with the second gear 46. The second rack 45 is fixedly mounted on the end of the movable plate 19. (Refer to...) Figure 9 When the movable plate 19 moves downward, it can drive the second rack 45 to move downward synchronously. When the second rack 45 moves, it can drive the second gear 46 to rotate counterclockwise. The third rack 48 is located on one side of the third gear 49 and meshes with the third gear 49. When the second gear 46 rotates counterclockwise, it can drive the third gear 49 to rotate synchronously and in the same direction. Since the third gear 49 and the third rack 48 mesh, when the third gear 49 rotates counterclockwise, it can drive the third rack 48 to move upward. Two sliding grooves 55 are opened on both sides of the surface of the movable frame 52. The first limiting rod 47 and the second limiting rod 50 are slidably arranged in the two sliding grooves 55 respectively. One end of the first limiting rod 47 and the second limiting rod 50 are fixedly installed on the second rack 45 and the third rack 48 respectively. It should be noted that the diameter of the second gear 46 is larger than the diameter of the third gear 49, which is used to reduce the moving stroke.

[0066] The sliding seat 53 is fixed to one side of the movable frame 52. A second guide rod 54 is inserted inside the sliding seat 53. The second guide rod 54 and the sliding seat 53 are connected by a sliding bearing. Both ends of the second guide rod 54 are fixed with fixing rods 56. The bottom end of each fixing rod 56 is fixed to the conveyor 11. Specifically, the bottom end of each fixing rod 56 is fixed to the frame of the conveyor 11.

[0067] The sliding groove 55 not only guides the first limiting rod 47 when it moves, but also, when the second rack 45 moves horizontally with the moving plate 19, the sliding seat 53 and the second guide rod 54 are slidably connected, and the first limiting rod 47 can drive the moving frame 52 to move synchronously, so that the second rack 45 and the third rack 48 are not easily separated from the second gear 46 and the third gear 49.

[0068] When the leather needs to be waxed, the lifting plate 16 first moves downward under the action of the adjustment mechanism. At this time, the lifting plate 16 can drive the moving plate 19 to move downward. The moving plate 19 drives the second rack 45 to move downward synchronously. When the second rack 45 moves, it can drive the second gear 46 to rotate counterclockwise. When the second gear 46 rotates counterclockwise, it can drive the third gear 49 to rotate synchronously and in the same direction. Since the third gear 49 and the third rack 48 are meshed, the third gear 49 can drive the third rack 48 to move upward when it rotates counterclockwise.

[0069] After waxing is completed, the lifting plate 16 moves upward under the action of the adjustment mechanism to achieve reset. The lifting plate 16 drives the moving plate 19 to move upward, and the moving plate 19 drives the second rack 45 to move upward synchronously. When the second rack 45 moves, it drives the second gear 46 to rotate clockwise. The second gear 46 drives the third gear 49 to rotate synchronously and in the same direction. At this time, the third rack 48 moves downward to achieve reset.

[0070] like Figures 1-10 As shown, each telescopic assembly includes an extension rod 51, a connecting rod 44, and two second hinged rods 43;

[0071] The extension rod 51 is fixedly installed at the bottom end of the third rack 48, and the connecting rod 44 is fixed at the bottom end of the extension rod 51 and close to one side of the two scrapers 39. One end of each second hinge rod 43 is hinged to the end of a scraper 39, and the other end of each second hinge rod 43 is hinged to the connecting rod 44. The two second hinge rods 43 are staggered.

[0072] Each scraper 39 has multiple vertical plates 41 fixed at its top end. Each vertical plate 41 has a first guide rod 42 slidably mounted in the middle via a sliding bearing. Both ends of each first guide rod 42 are fixed to the bottom end of the movable plate 19. The first guide rod 42 can play a guiding role.

[0073] When the leather needs to be waxed, the lifting plate 16 can drive the moving plate 19 to move downward. At this time, under the action of the transmission component, the extension rod 51 is driven to move upward. The extension rod 51 drives the connecting rod 44 to move upward. Under the action of the two second hinge rods 43, the two scrapers 39 can slide along the first guide rod 42, so that the two scrapers 39 move away from each other and release the blockage and obstruction of the drip hole 21. That is, during the process of the moving plate 19 moving downward, the two scrapers 39 can release the blockage of the drip hole 21.

[0074] After waxing is completed, the lifting plate 16 can drive the moving plate 19 to move upward. At this time, under the action of the transmission component, the extension rod 51 is driven to move downward. The extension rod 51 drives the connecting rod 44 to move downward. Under the action of the two second hinge rods 43, the two scrapers 39 can slide along the first guide rod 42, so that the two scrapers 39 move closer to each other, so as to scrape and seal the bottom of the drip hole 21. That is, during the upward movement of the moving plate 19, the two scrapers 39 can scrape off the excess oil and wax at the end of the drip hole 21 to prevent solidification and blockage of the drip hole 21, which would affect normal use. On the other hand, they can seal the ports of multiple drip holes 21 to prevent dust or other substances from entering and contaminating the oil and wax inside the drip hole 21, which would affect the waxing effect of the leather.

[0075] like Figures 1-10 As shown, the conveying assembly includes a storage tank 26, a pump body 25, a discharge pipe 24, a hose 23, and a discharge pipe 22;

[0076] Storage box 26 is fixedly installed on the top of lifting plate 16. Pump body 25 is located above storage box 26. The input end of pump body 25 is connected to the inner cavity of storage box 26. The output end of pump body 25 is connected to one end of discharge pipe 24. The other end of discharge pipe 24 is connected to one end of hose 23. Discharge pipe 22 is fixedly installed on the top of moving plate 19. The top of each drip hole 21 passes through moving plate 19 and is connected to discharge pipe 22. The end of hose 23 away from discharge pipe 24 is connected to the middle of discharge pipe 22.

[0077] When waxing is required, the pump body 25 is controlled to work. The pump body 25 can transport the wax inside the storage box 26 through the discharge pipe 24, hose 23, and discharge pipe 22 to the drip hole 21. Waxing is achieved through the drip hole 21, so that the wax can flow to the top of the leather, so that the wax can be evenly brushed on afterward to achieve even waxing.

[0078] Meanwhile, the flexible tube 23 does not affect the normal movement of the moving plate 19. Multiple drip holes 21 move with the moving plate 19, meaning that the wax flowing onto the leather can be brushed immediately, achieving the effect of feeding and coating evenly at the same time. This avoids the drawback of applying wax first and then brushing in the prior art, which easily causes the wax to solidify, and further improves the uniformity of waxing the leather.

[0079] like Figures 1-10 As shown, each lifting assembly includes a first cylinder 15, a lifting plate 57, two connecting plates 13, and two lifting rods 14;

[0080] Both lifting rods 14 are slidably mounted on one side of the conveyor 11. Specifically, the frame of the conveyor 11 has through holes, and the lifting rods 14 are slidably mounted inside the through holes for guidance. Each lifting rod 14 has a connecting plate 13 fixed at its top end, and the other end of each connecting plate 13 is fixedly connected to the pressure plate 12. The bottom ends of both lifting rods 14 are fixedly connected to the lifting plate 57. The lifting plate 57 connects the two lifting rods 14 on the same side. The first cylinder 15 is installed on one side of the conveyor 11. Specifically, the first cylinder 15 is installed on the frame of the conveyor 11, and the output end of the first cylinder 15 is fixedly connected to the bottom end of the lifting plate 57.

[0081] In use, initially, the pressure plate 12 is moved upward by the action of the first cylinder 15. When the leather moves to below the two pressure plates 12 by the action of the conveyor 11, the conveyor 11 is stopped. Then the first cylinder 15 is operated, and the first cylinder 15 drives the lifting plate 57 to move downward. Through the connection of the lifting rod 14 and the connecting plate 13, the pressure plate 12 can be moved downward, so that the bottom end of the pressure plate 12 can contact the leather and achieve the positioning of the leather.

[0082] like Figures 1-10 As shown, the adjustment mechanism includes a second cylinder 18 and four vertical rods 17. The four vertical rods 17 are symmetrically fixed at the top of the conveyor 11. Specifically, the four vertical rods 17 are all fixed on the frame in the conveyor 11. Each vertical rod 17 is inserted into the lifting plate 16. Each vertical rod 17 is slidably connected to the lifting plate 16 through a sliding bearing. The vertical rods 17 serve as guides. The second cylinder 18 is fixed at the top of one side of the conveyor 11. The output end of the second cylinder 18 is fixedly connected to the lifting plate 16.

[0083] In the initial state, the lifting plate 16 is moved to the top by the action of the second cylinder 18. At this time, the two bristles 20 are away from the conveyor 11. After the leather is fixed by the two pressure plates 12, the second cylinder 18 drives the lifting plate 16 to move downward, so that the bottom of the bristles 20 can contact the leather, so that the wax can be applied later to achieve a uniform waxing effect.

[0084] like Figures 1-10 As shown, a receiving plate 40 is fixed to the bottom of one of the scrapers 39 to serve as a receiving plate. When the two scrapers 39 approach each other to scrape the material from the bottom of the drip hole 21, the receiving plate 40 can collect the scraped wax to prevent the wax from dripping directly onto the leather and affecting the smoothness of the leather surface.

[0085] like Figures 1-10 As shown, the cross-section of the guide rail 35 is T-shaped, and the cross-sectional shape of the slide rod 36 matches the cross-sectional shape of the guide rail 35, so that when the lifting plate 16 is raised or lowered, it can drive the moving plate 19 to be raised or lowered, while not affecting the movement of the moving plate 19 below the lifting plate 16.

[0086] The specific working process of this invention is as follows:

[0087] First, place the leather to be waxed on the conveyor belt of the conveyor 11. The conveyor belt will move the leather. When the leather moves to the bottom of the two pressure plates 12, control the conveyor 11 to stop working. Then control the first cylinder 15 to work. The first cylinder 15 will move the lifting plate 57 downward. Through the connection of the lifting rod 14 and the connecting plate 13, the pressure plate 12 can be moved downward, so that the bottom end of the pressure plate 12 can contact the leather and achieve the positioning of the leather.

[0088] The second cylinder 18 is controlled to operate, causing the lifting plate 16 to move downwards. The lifting plate 16, in turn, causes the moving plate 19 to move downwards, allowing the bottom of the bristles 20 to contact the surface of the leather. Simultaneously, as the moving plate 19 moves downwards, it causes the second rack 45 to move downwards in sync. The second rack 45, in its movement, causes the second gear 46 to rotate counterclockwise. This counterclockwise rotation of the second gear 46, in turn, causes the third gear 49 to rotate synchronously and in the same direction. Because the third gear 49 and the third rack 48 are... The meshing mechanism allows the third gear 49 to rotate counterclockwise, which in turn drives the third rack 48 to move upward. The third rack 48 then drives the extension rod 51 to move upward, which in turn drives the connecting rod 44 to move upward. Under the action of the two second hinge rods 43, the two scrapers 39 can slide along the first guide rod 42, thus moving the two scrapers 39 away from each other and removing the blockage and obstruction of the drip hole 21. In other words, during the downward movement of the moving plate 19, the two scrapers 39 can remove the blockage of the drip hole 21, making it easier for the wax to flow out from the drip hole 21.

[0089] Then, the pump body 25 is controlled to work. The pump body 25 can transport the wax inside the storage box 26 through the discharge pipe 24, hose 23, and discharge pipe 22 to the drip hole 21, and waxing is achieved through the drip hole 21, so that the wax can flow to the top of the leather.

[0090] While the wax oil is being delivered, the drive motor 31 operates, which in turn drives the lead screw 29 to rotate. Due to the threaded engagement between the lead screw 29 and the sliding block 28, and the sliding connection between the sliding block 28 and the slotted groove 27, the rotation of the lead screw 29 causes the sliding block 28 to slide within the slotted groove 27, thus enabling its movement. As the sliding block 28 moves along the length of the slotted groove 27, it drives the rotating rod 32 to move. At this time, the first gear 33 moves along with the rotating rod 32. Since the first gear 33 meshes with the first rack 34, the first gear 33 moves... The first gear 33 can rotate around the axis of the rotating rod 32, so that the first gear 33 moves and rotates at the same time. When the first gear 33 rotates, it drives the turntable 37 to rotate through the rotating rod 32. Under the action of the first hinge rod 38, the moving plate 19 can achieve a small-amplitude reciprocating motion. At the same time, since the sliding block 28 can move linearly along the strip groove 27, the screw 29 can perform a small-amplitude reciprocating motion while moving along the length direction of the strip groove 27. This allows the two bristles 20 to brush the entire surface of the leather in a small amplitude, avoiding any omissions in the application. This helps to improve the uniformity of the waxing and enhance the waxing effect.

[0091] After waxing is complete, the pump body 25 and motor 31 stop working. Simultaneously, the second cylinder 18 drives the moving plate 19 to move upward, preventing the brush bristles 20 from contacting the leather. The first cylinder 15 drives the pressure plate 12 to move upward, also preventing it from contacting the leather, thus facilitating the leather's movement to the next process via the conveyor 11. At the same time, the moving plate 19 drives the second rack 45 to move upward synchronously. The second rack 45, while moving, drives the second gear 46 to rotate clockwise. The second gear 46 then drives the third gear 49 to rotate synchronously and in the same direction. At this point, the third rack 48 moves downward to reset, and the third rack 48 drives the extension rod 51 to move downward. When the extension rod 51 moves, it drives the connecting rod 44 to move downward. Under the action of the two second hinge rods 43, it can drive the two scrapers 39 to slide along the first guide rod 42, so that the two scrapers 39 move closer to each other, and scrape and seal the bottom of the drip hole 21. That is, when the moving plate 19 moves upward, the two scrapers 39 can scrape off the excess oil and wax at the end of the drip hole 21 to prevent solidification and blockage of the drip hole 21, which would affect normal use. On the other hand, they can seal the ports of multiple drip holes 21 to prevent dust or other substances from entering and contaminating the oil and wax inside the drip hole 21, which would affect the waxing effect of the leather.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
