Description

Technical Field

[0001] The present application relates to the field of synthetic leather manufacturing, and in particular to a synthetic leather feeding mechanism. Background Art

[0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as a substitute material. It is usually made of impregnated non-woven fabric as the mesh layer and microporous polyurethane layer as the grain layer. Both its front and back sides are very similar to leather and have a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather.

[0003] In the production process of synthetic leather, non-woven fabric and release paper need to be laminated to enter the next process. However, the current market demand has two different widths of synthetic leather materials, about 1.4m and about 2.1m. If the wider production line is always used for production, there will be some shortcomings in terms of mold matching and use effect. Purchasing two sets of production lines is beyond the budget of most manufacturers. It is expected that there will be a production equipment that can meet the production needs of different widths.

[0004] On the other hand, after the synthetic leather slurry is loaded, the surface needs to be coated with silicone oil. In the prior art, the silicone oil loading step is still done manually, pouring the silicone oil into the loading space. This requires manual management. In our solution, a diverter box is set up to load the silicone oil, and the production line can be adjusted by controlling the flow rate. Utility Model Content

[0005] Therefore, it is necessary to provide a synthetic leather feeding mechanism to solve the problem that the production line of the synthetic leather laminating process in the prior art requires manual feeding and is inefficient.

[0006] To achieve the above object, the inventor provides a synthetic leather feeding mechanism, comprising:

[0007] A guide roller is provided above the front of the guide roller.

[0008] A hopper is provided at the rear of the hopper, a scraper is provided, a feeding space is formed between the hopper and the scraper, and a

[0009] The diverter box comprises a box body and diverter ports, the bottom of the box body is a horizontal plane, and the diverter ports are arranged at equal intervals at the bottom of the box body.

[0010] In some embodiments, the hopper includes a first arm and a second arm, and a distance between the first arm and the second arm is adjustable.

[0011] In some embodiments, further comprising

[0012] A hopper connecting portion, wherein the hopper is detachably mounted on the hopper connecting portion.

[0013] In some embodiments, the hopper connection portion is connected to the hopper by means of snap-fitting, plug-in or threaded nut.

[0014] In some embodiments, the diverter box is further connected to a diverter box translation device, and the diverter box translation device is connected to a driving device.

[0015] In some embodiments, further comprising

[0016] An injection pipe is used to inject paint into the diversion box, and the injection pipe is connected to the material storage box.

[0017] In some embodiments, the injection tube is also connected to an electronic pump.

[0018] In some embodiments, a control circuit is also included, and the control circuit also includes a flow meter. The flow meter is arranged at the diversion port at the edge of the diversion box. The flow meter is used to close the control circuit after detecting the flow. The control circuit is used to control the opening of the electronic pump.

[0019] Different from the prior art, in the synthetic leather feeding mechanism described in the above technical scheme, in the silicone oil application process, the distance between the scraper and the synthetic leather fabric is the thickness of the silicone oil applied on the surface. The feeding space formed by the hopper and the scraper is used to temporarily store the silicone oil coating and limit the flow area of ​​the coating to limit the width of the slurry that can be applied to the non-woven fabric, without the need for manual application of the restricted slurry area; the dividing box is dedicated to storing coatings and is used in the oiling production line. Since silicone oil has good fluidity, silicone oil will not clog the diverter box. Therefore, the design of the diverter box can enable the coating to rely on gravity to flow autonomously from the dividing port into the hopper, thereby realizing autonomous feeding without manual pouring. Therefore, the utility model has the advantages of efficient feeding to complete autonomous slurry application, saves labor costs, and has a more accurate application range.

[0061] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as a substitute material. It is usually made of impregnated non-woven fabric as the mesh layer and microporous polyurethane layer as the grain layer. Both its front and back sides are very similar to leather and have a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather.

[0062] In the production process of synthetic leather, non-woven fabric and release paper need to be laminated to enter the next process. After the synthetic leather slurry is loaded, silicone oil needs to be applied on the surface. In the prior art, the silicone oil application step still adopts the manual loading method to pour the silicone oil into the loading space. This requires manual management. In our solution, the silicone oil application method of setting a diverter box 5 can control the flow rate to match the production line.

[0063] To this end, the utility model provides a synthetic leather feeding mechanism to solve the problem in the prior art that the production line of the synthetic leather bonding process requires manual feeding and manual adjustment of the slurry / paint coating width, resulting in low efficiency.

[0064] See also Figure 1 and Figure 2 In a specific embodiment, the synthetic leather feeding mechanism includes a guide roller 1, a hopper 3 is arranged above the front of the guide roller 1, a scraper 4 is arranged behind the hopper 3, a feeding space is formed between the hopper 3 and the scraper 4, a diverter box 5 is arranged above the feeding space, the diverter box 5 includes a box body and a diverter port 500, the bottom of the box body is a horizontal plane, and the diverter ports 500 are arranged at equal intervals at the bottom of the box body.

[0065] The slurry in this article generally refers to the raw material of synthetic leather fabric, polyurethane slurry. Coating generally refers to surface coating such as silicone oil coating and the like. The synthetic leather feeding mechanism flattens the slurry through the scraper 4 to limit the thickness of the slurry coating. Specifically, there is a distance between the scraper 4 and the conveyor belt 2, and the distance is the thickness of the slurry coated on the non-woven fabric; in the silicone oil coating process, the distance between the scraper 4 and the synthetic leather fabric is the thickness of the silicone oil coated on the surface. The feeding space formed by the hopper 3 and the scraper 4 is used to temporarily store the silicone oil coating and limit the flow area of ​​the coating to limit the width of the slurry that can be applied to the non-woven fabric, without the need for manual coating to limit the slurry area; in some embodiments of the present application, the material distribution box is dedicated to storing coatings and is applied to the oiling production line. The inventor found that the polyurethane slurry is easy to harden and is easily blocked by mechanical feeding. Since silicone oil has good fluidity, silicone oil will not clog the diverter box 5. Therefore, the design of the diverter box 5 can enable the paint to flow into the hopper 3 from the distributing port autonomously by gravity, thereby realizing autonomous loading without manual pouring. Therefore, the utility model has the advantages of efficient loading to complete autonomous slurry coating, saving labor costs, and a more accurate coating range.

[0066] The guide roller 1 is a guide roller 1 inside a synthetic leather conveying mechanism. Specifically, the synthetic leather conveying mechanism includes a conveyor belt 2, a guide roller 1 and a guide roller power mechanism. The conveyor belt 2 is ring-shaped and is supported by two guide rollers 1 to be stretched straight. The guide roller power mechanism drives the guide roller 1 to rotate to drive the conveyor belt 2 to move. The non-woven fabric is laid on the conveyor belt 2 and moves with the movement of the conveyor belt 2.

[0067] In order to ensure that the diverter box 5 can be continuously replenished with paint, please refer to Fig. 9 In some embodiments, the synthetic leather feeding mechanism also includes an injection pipe 8, which is used to inject paint into the diversion box 5. The injection pipe 8 is connected to the storage box 9. The injection pipe 8 is connected to the storage box 9 through an electronic pump 10. The electronic pump 10 continuously draws out the slurry in the storage box 9 and flows into the diversion box 5 through the injection pipe 8.

[0068] See also Figure 3 In a further embodiment, the diverter box 5 is provided with a plurality of diverter ports 500, and the plurality of diverter ports 500 can be arranged at equal intervals horizontally (i.e., orthogonal to the conveying direction of the conveying mechanism) at the bottom of the diverter box 5, and can be provided with one row or at least two rows. Such an arrangement can more evenly pour the slurry into the upper material space.

[0069] In some embodiments, the synthetic leather feeding mechanism further comprises a control circuit. Fig.10 , further comprising a flow meter 501, wherein the flow meter 501 is disposed at the outermost diversion 500 in the diversion box 5, and wherein the flow meter 501 is used to close the control circuit after detecting the flow, and the control circuit is used to control the opening of the electronic pump 10. The injection pipe 8 is connected to the middle part of the top of the diverter box 5, and the supplementary paint is injected into the diverter box 5 from the middle part of the top of the diverter box 5 downward. The slurry injected into the diverter box 5 is gradually spread out to the surroundings evenly under the action of gravity. If there is enough paint in the diverter box 5, it will inevitably flow to the diverter 500 at the outermost edge of the diverter box 5. Therefore, the paint flow rate at the diverter 500 at the outermost edge of the diverter box 5 can be used as a basis for judging whether the amount of paint in the diverter box 5 is sufficient. The paint flow rate at the diverter 500 at the outermost edge of the diverter box 5 can be detected by the flow meter 501. If the flow rate is small, it means that the amount of paint in the diverter box 5 is insufficient, and the electronic pump 10 can be started to replenish the paint. If the flow rate is large, it means that the amount of paint in the diverter box 5 is sufficient, and the electronic pump 10 can be turned off to stop replenishing the paint, so as to avoid too much paint in the diverter box 5, resulting in too high a flow rate, so that there is too much paint in the feeding space, so as to avoid overflow of too much paint in the feeding space of the conveying mechanism, resulting in waste.

[0070] In order to prevent the hopper 3 from affecting the movement of the conveyor belt 2 when it is installed on the conveyor belt 2, and to prevent the slurry from leaking from the gap between the conveyor belt 2 and the hopper 3, please refer to Figure 1 In a further embodiment, a sealing strip 303 is provided at the bottom of the hopper 3. The sealing strip 303 can be a silicone strip or a rubber strip, etc., and has a certain degree of flexibility and deformation. When it is against the conveyor belt 2, it can deform with the movement of the conveyor belt 2 to cooperate with the movement of the conveyor belt 2. It also has sealing properties to prevent the slurry from leaking out from between the conveyor belt 2 and the hopper 3.

[0071] The transverse width of the diverter box 5 (i.e. the width perpendicular to the conveying direction of the conveying mechanism) can be consistent with the width of the loading space, or can be set to be smaller than the width of the loading space, preferably set to be smaller than the width of the loading space, which can save manufacturing materials and save costs. In this way, it can be adapted to the following hopper 3 with adjustable transverse width.

[0072] The current market demand has two different widths of synthetic leather materials, about 1.4m and about 2.1m. If the wider production line is always used for production, there will be some shortcomings in terms of mold matching and use effect. Purchasing two sets of production lines is beyond the budget of most manufacturers. It is expected that there will be a production equipment that can meet the production needs of different widths.

[0073] Therefore, in order to adapt to the production of synthetic leather of different widths, please refer to Figure 1 and Figure 4 In some embodiments, the hopper 3 includes a first arm 300 and a second arm 301, and the distance between the first arm 300 and the second arm 301 is adjustable, so that the production line of the synthetic leather bonding process can simultaneously match the production of synthetic leathers of various widths. If you want to make synthetic leathers of smaller widths, adjust the distance between the first arm 300 and the second arm 301 to limit the lateral width of the loading space (i.e., the width orthogonal to the conveying direction of the conveying mechanism), thereby limiting the lateral width of the slurry applied to the non-woven fabric. The user can adjust the distance between the first arm 300 and the second arm 301 according to the specific situation, so that synthetic leathers with various width requirements can be produced by relying on one set of production lines, thereby reducing production costs, reducing equipment space occupied, and being highly flexible.

[0074] The first arm 300 and the second arm 301 are specifically plate-shaped, and are the left and right plates of the hopper 3. In a further embodiment, a baffle 302 is arranged between the first arm 300 and the second arm 301. The hopper 3 is surrounded by the baffle 302, the first arm 300 and the second arm 301, and together with the scraper 4, encloses a feeding space.

[0075] In a further embodiment, the hopper 3 is mounted on the conveying mechanism through a hopper mounting frame 6. In one embodiment, the hopper 3 includes a first arm 300 and a second arm 301. The distance between the first arm 300 and the second arm 301 is adjustable. By setting a track on the hopper mounting frame 6, pulleys are set on the first arm 300 and the second arm 301, and the first arm 300 and the second arm 301 can be installed on the hopper mounting frame 6 in a transversely movable manner. The hopper mounting frame 6 can be connected to one or two arms. In another embodiment, the hopper mounting frame 6 can be connected to the baffle 302. The mounting frame can be set in front of the guide roller 1, that is, in the upper production line direction of the feeding space. The mounting frame can also be set in the lower production line direction of the feeding space, such as above the scraper 4.

[0076] See also Figure 5 In another embodiment, the first arm 300 and the second arm 301 are both disposed at the baffle 302 so as to be laterally movable. Specifically, the baffle 302 is provided with a first slide rail 304. The first arm 300 and the second arm 301 are both disposed at the rail and can be fixed at their positions by a locking member, such as a bolt, and the baffle 302 is connected to the hopper mounting frame 6. In this embodiment, the lateral width of the baffle 302 should be relatively large, so that a variety of synthetic leathers having widths not greater than the lateral width of the baffle 302 can be manufactured.

[0077] In order to adapt to the production of synthetic leathers of different widths, in other embodiments, the hopper 3 may be provided with a plurality of hoppers 3, and the lateral widths of different hoppers 3 are different. For example, a hopper 3 with a lateral width of 1.4 m may be provided (such as Figure 6 ) and a hopper 3 with a transverse width of 2.1 m (as shown Figure 7 As shown), users can install hoppers 3 with different lateral widths on the conveying mechanism according to different needs.

[0078] See also Figure 7 and Figure 8 In some embodiments, a hopper connection portion is further included, and the hopper 3 is detachably mounted on the hopper connection portion. Users can install hoppers 3 of different lateral widths at the hopper connection portion according to different needs.

[0079] In a further embodiment, the hopper connection portion is arranged at the hopper mounting frame 6.

[0080] In some embodiments, the hopper connection portion is connected to the hopper 3 by means of a snap connection, a plug connection or a threaded nut, see Figure 6 For example, the hopper 3 is provided with a limit block 3020, and the hopper connecting portion is provided in the limit groove. The hopper 3 is detachably mounted on the hopper mounting portion through the docking of the limit block 3020 and the limit groove.

[0081] In order to better adapt to the production of synthetic leathers of different widths and avoid the impact of material feeding after switching from long-width synthetic leather production to short-width synthetic leather production, please refer to Fig. 9 In some embodiments, the lateral width of the diverter box 5 is set to be smaller than the lateral width of the conveying mechanism, and the diverter box 5 is also connected to the diverter box translation device 7, and the diverter box translation device 7 is connected to the driving device. After the production of long-width synthetic leather is switched to the production of short-width synthetic leather, the position of the diverter box 5 can be moved so that the diverter box 5 can be moved to the center position of the loading space at this time to ensure that all the slurry in the diverter box 5 can flow into the loading space at this time, adapting to the loading requirements of loading spaces of different widths.

[0082] The diverter box translation device 7 includes a diverter box mounting frame and a second track, the second track is horizontally arranged at the diverter box mounting frame and is located above the loading space, the diverter box 5 is arranged at the second track through a slider, and the driving device can be of various types, such as a manual driving structure, a screw with a rocker, the screw with the rocker thread passes through the slider, and the slider is driven to move along the second track by shaking the rocker, thereby adjusting the position of the diverter box 5; such as an electric driving structure, a servo motor, and the slider is driven by a motor to move along the second track.

[0083] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
