Description

Technical Field

[0001] This utility model relates to the field of synthetic leather feeding structures, specifically a feeding structure for a dry synthetic leather production line. Background Technology

[0002] In the production process of synthetic leather, the feeding structure of the dry synthetic leather production line plays a crucial role. Dry synthetic leather production is a common process that involves coating raw materials such as resin onto a base fabric and then processing it through a series of steps to produce synthetic leather. As a key part of the production line, the feeding structure is responsible for accurately and stably delivering materials such as coatings and additives to the production process, ensuring that the base fabric can evenly absorb the coatings, thereby guaranteeing the quality and performance of the synthetic leather. Its precise feeding control directly affects many aspects of the synthetic leather, such as color uniformity, surface smoothness, and physicochemical properties, making it an indispensable part of synthetic leather production.

[0003] However, in terms of mixing, the traditional mixing mechanism in the dry synthetic leather production line has a fixed position, making it difficult to adjust according to different production needs. Since the viscosity of the coating varies due to formulation and environmental factors, and the material of the fabric is also diverse, the actual production process is even more complex and variable. The fixed position of the mixing mechanism cannot meet these diverse needs, resulting in poor mixing effect, which in turn affects the uniformity and applicability of the coating. In addition, the traditional feeding mechanism is also fixed in position. When coating synthetic leather, this fixed position can easily interfere with the coating effect. During the coating process, the feeding mechanism may hinder the normal movement of the synthetic leather, thereby affecting the uniformity and integrity of the coating. Therefore, we propose a feeding structure for the dry synthetic leather production line. Utility Model Content

[0009] Preferably, the stirring mechanism includes a lead screw, a mixer, a second motor, a column, and a sliding support plate. Columns are symmetrically fixedly installed on the upper half of the two vertical axial surfaces of the bracket opening, corresponding to the upper part of the fixed block of the bracket.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a feeding structure for a dry synthetic leather production line, which has the following beneficial effects:

[0015] 1. The feeding structure of the traditional synthetic leather dry process production line has a fixed position for the mixing mechanism, which is difficult to adjust according to different production needs, resulting in poor mixing effect and affecting the uniformity and applicability of the coating. In the mixing mechanism of this device, the lead screw, motor and sliding support plate cooperate with each other to make the sliding support plate slide up and down on the column, thereby adjusting the height of the mixer. This design can flexibly change the position of the mixer according to the viscosity of the coating, the material of the fabric and the requirements of the actual production process, to ensure that the coating is mixed in all directions and in multiple layers, and to ensure that the coating is always in a uniform and applicable state.

[0016] 2. The feeding structure of this dry synthetic leather production line: Traditional feeding mechanisms are fixed in position. When coating synthetic leather, this fixed position can easily interfere with the coating effect. During the coating process, the motor drives the pulley and belt to rotate, allowing the sliding plate to slide backward on the sliding base. This cleverly provides sufficient coating space for the synthetic leather, does not affect the smooth progress of the coating process, and avoids spatial conflicts between the feeding mechanism and the coating area. The suction pipe stably connects the storage box and the feeding machine, ensuring the continuity of material transportation. Attached Figure Description

[0029] Structural Description:

[0030] Support 1: It is rectangular in shape with a square groove on the bottom and an opening on the side that is connected to the square groove. It is the main support of the entire device and provides installation positions for other components through its own structure. The storage box 7 is fixedly installed on its upper surface away from the opening. The roller and fixing mechanism are set in its square groove. The feeding mechanism is installed on the upper surface in front of the corresponding storage box 7. The stirring mechanism is fixed on the opening surface in front of the corresponding feeding mechanism.

[0031] Storage bin 7: A container with a certain volume, used to store paint. It is fixedly placed on the upper surface of the bracket 1 away from the opening by a fixed installation method. It stores the materials required for production and is connected to the feeder 11 through the suction pipe 17 to provide the material source for the feeding process.

[0032] Roller and fixing mechanism:

[0033] Inclined fixing plate 3: It is connected by snapping into the inclined snap-fit ​​groove on the fixing block of bracket 1. There is a gap between its lower end and roller 4. It cooperates with baffle 14 to form a cavity for placing paint, which plays a role in blocking and positioning the paint.

[0034] Roller 1 4: It is cylindrical and is installed in the square groove of the bracket 1 near the opening by means of rotational connection. It is parallel to and corresponds to roller 2 5. The two form a channel for the fabric to pass through, which is used to guide the movement of the fabric. At the same time, it works with the paint in the receiving cavity to make the fabric evenly coated with paint during the movement.

[0035] Roller 2 5: Also cylindrical, it is installed in the square groove of bracket 1, corresponding to the oblique upper part of roller 1 4, by a rotating connection. It works together with roller 1 4 to guide the fabric through and ensure that the fabric can fully contact the coating when passing through.

[0036] Baffle 14: The side is provided with an inclined groove and a quarter circle groove. The inclined groove is engaged with the inclined fixing plate 3. The quarter circle groove corresponds to the roller 4 and is symmetrically slidably connected on the roller 4. Together with the inclined fixing plate 3 and the roller 4, it forms a cavity for placing the paint, preventing the paint from overflowing and ensuring that the paint contacts the fabric in a specific area.

[0037] Stirring mechanism:

[0038] Lead screw 6: A slender rod with its axis coaxially connected to the threaded hole of column 18. Driven by motor 2 15, it rotates and drives the sliding support plate 19 to move up and down through the threaded connection with the sliding support plate 19, thereby adjusting the height of mixer 10.

[0039] Mixer 10: Symmetrically fixedly installed on the bottom surface of sliding support plate 19, located above the receiving cavity formed by baffle 14, inclined fixed plate 3 and roller 4. Its function is to stir the coating in the receiving cavity to ensure the coating is uniform and to meet production requirements.

[0040] Motor 2 15: It is fixedly installed on the bottom surface of column 18. The output shaft passes through the threaded hole of column 18 and is fixedly connected to lead screw 6 to provide power for the rotation of lead screw 6, thereby realizing the adjustment of the height of mixer 10;

[0041] Column 18: hollow inside, column-shaped, symmetrically fixed above the fixing block of bracket 1 on the upper half of the two vertical axis surfaces of the bracket 1 opening. Its internal structure and the threaded holes, sliding grooves, etc., provide the basis for the installation and movement of components such as screw 6 and sliding support plate 19.

[0042] Sliding support plate 19: Sliding blocks are symmetrically fixed on both sides. A threaded hole is opened on the upper surface near the sliding block. The sliding block is engaged with the sliding groove of the column 18 and slidably connected. The threaded hole is threadedly connected to the lead screw 6. It slides up and down under the drive of the lead screw 6, thereby adjusting the position of the mixer 10.

[0043] Feeding mechanism:

[0044] Sliding base 8: Symmetrically fixedly installed on the upper surface of the bracket 1 in front of the storage box 7, with sliding grooves on the two sides near the top to provide a track for the sliding plate 9 to slide.

[0045] Pulley 12: It is disc-shaped, one of which is connected to the sliding base 8 by rotating back and forth. The two pulleys 12 are connected by a belt 13. Under the drive of the motor 16, the belt 13 is driven to rotate, thereby providing power for the movement of the sliding plate 9.

[0046] Belt 13: An annular belt that connects two pulleys 12 to realize power transmission between the pulleys 12. At the same time, it drives the sliding plate 9 to move through its connection with the fixed block of the sliding plate 9.

[0047] Motor 3 16: It is fixedly installed on the outer wall of the sliding base 8. The transmission shaft is coaxially fixedly connected to one of the pulleys 12, providing power for the rotation of the pulley 12. It is the power source for the movement of the sliding plate 9 in the feeding mechanism.

[0048] Sliding plate 9: A sliding block is symmetrically fixed on the bottom surface, and a fixed block is fixed next to one of the sliding blocks. The sliding block is engaged with and slidably connected to the sliding groove of the sliding base 8. The fixed block is fixedly connected to one side of the belt 13. Under the drive of the belt 13, it slides on the sliding base 8, thereby driving the feeder 11 to move.

[0049] Feeder 11: Fixedly installed on the bottom surface of the sliding plate 9 at the position between the two sliding blocks, it draws material from the storage box 7 through the suction pipe 17 and adds the material to the designated position according to the movement of the sliding plate 9, so as to achieve precise feeding;

[0050] Suction pipe 17: A tubular structure, one end of which is connected to the storage box 7 and the other end is connected to the feeder 11. It is used to transport the material in the storage box 7 to the feeder 11 to ensure that the feeder 11 has enough material for the feeding operation.

[0051] Working principle: Pour paint into storage bin 7 and transport the paint in storage bin 7 to feeder 11 through suction pipe 17 to prepare for subsequent feeding. At the same time, place the fabric to be processed at the starting position of the channel formed between roller 1 4 and roller 2 5.

[0052] When motor 316 is started, the drive shaft of motor 316 drives pulley 12 to rotate. Since the two pulleys 12 are connected by belt 13, the other pulley 12 also rotates, which in turn drives belt 13 to rotate. Belt 13 is connected to the fixed block of sliding plate 9, so that sliding plate 9 slides on sliding groove of sliding base 8. Since feeder 11 is fixedly installed on sliding plate 9, feeder 11 will also move with sliding plate 9. When it moves to the space between two baffles 14 and inclined fixed plate 3 and roller 14 to form a cavity for placing paint, motor 316 is turned off, and feeder 11 adds the paint it has sucked up into the cavity.

[0053] As the fabric is driven by the production line, it enters the channel between roller 4 and roller 5. At this time, an appropriate amount of paint has been added to the cavity formed between the two baffles 14, the inclined fixing plate 3 and roller 4. The fabric moves forward under the guidance of roller 4 and roller 5. During the movement, it comes into full contact with the paint in the cavity, so that the paint is evenly adhered to the fabric. The inclined fixing plate 3 and the baffle 14 play the role of blocking and positioning the paint, preventing the paint from overflowing, and ensuring that the paint contacts the fabric in a specific area.

[0054] After the paint has been left to stand for a period of time, it will separate into layers. At this time, the stirring mechanism starts to work. Motor 2 15 starts, and its output shaft drives the lead screw 6 to rotate in the threaded hole of the column 18. Since the threaded hole of the sliding support plate 19 is threadedly connected to the lead screw 6, and the sliding block is engaged with the sliding groove of the column 18, the rotation of the lead screw 6 drives the sliding support plate 19 to slide up and down along the sliding groove of the column 18. The mixer 10, which is fixed to the bottom surface of the sliding support plate 19, will also move up and down accordingly to stir the paint in the container cavity, ensuring that the paint always remains in a uniform state and meets the production requirements for paint uniformity.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
