Description

Technical Field

[0001] The utility model relates to the technical field of synthetic leather processing, in particular to a surface release paper flattening device used in synthetic leather production. Background Art

[0002] Release paper is a kind of anti-stick paper that prevents prepreg from sticking and protects prepreg from contamination. Release paper is made of paper coated with anti-stick material. During the production process of synthetic leather, release paper needs to be pressed on the surface to provide a certain degree of surface protection. In order to ensure that the pressed release paper and the leather base are fully adhered, the pressed synthetic leather needs to be flattened by a flattening roller in turn.

[0003] For example, the Chinese patent technology document with the announcement number CN218084623U discloses a flattening structure and a release paper laminating device, including: a first baffle and a second baffle, the first baffle and the second baffle are parallel to each other, and the outer side of the fixed shaft is rotatably sleeved with a movable sleeve; two threaded columns are respectively fixed to the ends of the two fixed shafts located at both ends of the first baffle, the connecting tube is movably connected with the second baffle, and both ends of the connecting tube are fixedly connected to the limiting ring; the driving wheel and the two adjusting wheels are connected by a transmission belt.

[0004] In the above technical solution, the distance between the first baffle and the second baffle can be adjusted by moving the first baffle away from or closer to the second baffle, so that the limit rings on the first baffle and the second baffle can position the release paper and the base paper after bonding during the process of the release paper and the base paper passing through the flattening roller, thereby avoiding the release paper and the base paper from being misaligned with each other during flattening.

[0005] However, in the above technical solution, the adjustment of the distance between the first baffle and the second baffle is mainly through the movement of the first baffle. Therefore, when it is necessary to make the limit rings on both sides abut against the sides of the release paper and the base paper, it is not fast enough, thereby affecting the overall flattening efficiency. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a surface release paper flattening device for synthetic leather production, which can make the limiting ring quickly abut against both sides of the synthetic leather to achieve rapid positioning of the synthetic leather.

[0007] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0008] The utility model is further configured as follows: the sleeve portion is connected to a positioning ring, the outer periphery of the positioning ring is provided with a positioning portion offset outward, and the positioning portion is adapted to the cross section of the flattened sleeve.

[0009] The utility model is further configured as follows: a first threaded hole is provided on the positioning ring, the first threaded holes are multiple and evenly distributed along the circumference, a second threaded hole opposite to the first threaded hole is provided on the sleeve portion, and a countersunk hole is provided on the positioning ring that is concentric with the first threaded hole.

[0010] The utility model is further configured as follows: a mounting seat is provided between the support plates on both sides, a positioning opening is provided on the mounting seat, a slidable positioning rod is provided in the positioning opening, a connecting seat is fixed at one end of the positioning rod away from the mounting seat, the connecting seat is rotatably connected to an abutment wheel on the side facing the winding roller, a spring is sleeved on the positioning rod, one end of the spring is fixed to the connecting seat, and the other end is fixed to the mounting seat, and a press switch is provided on the side of the mounting seat facing the connecting seat.

[0011] The utility model is further configured as follows: a bracket is fixed on the base, a horizontally arranged waist adjustment hole is provided on the bracket, a threaded portion extending to the waist adjustment hole is provided on the mounting seat, and the threaded portion is locked by a nut.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] After the synthetic leather passes through the flattening sleeve and is pulled to the winding roller in turn, the adjusting motor drives the bidirectional lead screw to rotate, so that the connecting plate which is sleeved on the end of the bidirectional lead screw and forms a threaded fit can move along the direction of the bidirectional lead screw under the action of the guide rod, so that the limiting rings on the connecting plates on both sides can move at the same time, and can then abut against both sides of the synthetic leather more quickly to reduce the adjustment time, thereby ensuring the overall flattening efficiency of the synthetic leather in disguise. Therefore, it effectively solves the technical problem in the prior art that the limiting ring can only move on one side, resulting in too long an adjustment time for the limiting ring. Subsequently, the synthetic leather can be pulled and straightened by rotating the winding roller, so that the flattening sleeve sleeved on the sleeve part can rotate under the action of friction to complete the flattening of the surface of the synthetic leather.

[0020] like Figures 1 to 4As shown, the utility model discloses a surface release paper flattening device for synthetic leather production, including a base 1, a support plate 2 is symmetrically fixed on the base 1, a bidirectional screw 3 is rotatably connected between the support plates 2 on both sides, an adjusting motor 4 is provided on the outside of the support plate 2, the adjusting motor 4 is used to drive the bidirectional screw 3 to rotate, guide rods 5 are provided on both sides of the bidirectional screw 3, the guide rods 5 are fixed to the support plate 2, a connecting plate 6 is symmetrically provided between the support plates 2 on both sides, the connecting plate 6 is sleeved on the bidirectional screw 3 and the guide rod 5, and respectively forms a threaded fit and a sliding fit with the bidirectional screw 3 and the guide rod 5, a connecting rod 7 is provided between the connecting plates 6 on both sides, the connecting rod 7 includes a sleeve portion 71 and a telescopic portion 72, a sliding cavity 711 is provided in the sleeve portion 71, one end of the telescopic portion 72 is fixed to the connecting plate 6, and the other end extends to the sliding cavity 711 and can slide in the sliding cavity 711, the telescopic portion 7 2 A limit ring 8 is fixed at one end close to the sleeve portion 71. The sleeve portion 71 is provided with a flattening sleeve 9. A winding roller for winding is provided above the base 1. After the synthetic leather passes through the flattening sleeve 9 in turn and is pulled to the winding roller, the adjusting motor 4 drives the bidirectional lead screw 3 to rotate, so that the connecting plate 6 sleeved on the end of the bidirectional lead screw 3 and threadedly engaged can move along the direction of the bidirectional lead screw 3 under the action of the guide rod 5, so that the limit rings 8 on the connecting plates 6 on both sides can move at the same time, and then can abut against both sides of the synthetic leather more quickly, so as to reduce the adjustment time and indirectly ensure the overall flattening efficiency of the synthetic leather. Subsequently, the synthetic leather can be pulled and straightened by rotating the winding roller. In this way, the flattening sleeve 9 sleeved on the sleeve portion 71 can rotate under the action of friction to complete the flattening of the surface of the synthetic leather.

[0021] In this embodiment, a positioning ring 10 is further connected to the sleeve portion 71. The outer periphery of the positioning ring 10 is provided with a positioning portion 101 offset outward. The positioning portion 101 is adapted to the cross-section of the flattening sleeve 9. The positioning ring 10 can limit the flattening sleeve 9 to prevent the flattening sleeve 9 sleeved on the sleeve portion 71 from axial deviation.

[0022] Among them, the connection structure between the positioning ring 10 and the sleeve part 71 is that a first threaded hole is provided on the positioning ring 10, and the first threaded holes are multiple and evenly distributed along the circumference. A second threaded hole opposite to the first threaded hole is provided on the sleeve part 71, and a countersunk hole 102 is provided on the positioning ring 10 concentrically arranged with the first threaded hole. Therefore, the detachable connection between the positioning ring 10 and the sleeve part 71 can be achieved by screwing in or out the locking member 100 that forms a threaded fit with the first threaded hole and the second threaded hole. The setting of the countersunk hole 102 can prevent the end of the locking member 100 from protruding outward after the locking member 100 is screwed into the first threaded hole and the second threaded hole, thereby preventing the surface of the synthetic leather from being damaged.

[0023] In this embodiment, a mounting seat 11 is further provided between the support plates 2 on both sides, and a positioning hole is provided on the mounting seat 11, and a slidable positioning rod 12 is provided in the positioning hole. The positioning rod 12 is located at one end away from the mounting seat 11 and is fixed with a connecting seat 13. The connecting seat 13 is located on the side facing the winding roller and is rotatably connected to the abutment wheel 14. A spring 15 is set on the positioning rod 12, and one end of the spring 15 is fixed to the connecting seat 13 and the other end is fixed to the mounting seat 11. The mounting seat 11 is located on the side facing the connecting seat 13 and is provided with a press switch 16. As the winding roller continues to rewind the synthetic leather, the synthetic leather wound around the winding roller continues to thicken, thereby passing through the abutment wheel 14. The connecting seat 13 is driven to move toward the mounting seat 11 until the connecting seat 13 contacts the push switch 16, and the winding roller can be stopped. That is, after the push switch 16 is turned on, a corresponding control signal is sent to the PLC controller. After receiving the control signal, the PLC controller can control the corresponding motor to stop. Then, the worker can cut the synthetic leather to achieve the fixed-length winding of the synthetic leather. During the movement of the connecting seat 13, the positioning rod 12 can slide in the positioning port to guide the movement of the connecting seat 13. Then, after the synthetic leather on the winding roller is removed, the spring 15 can stop being compressed, thereby driving the connecting seat 13 to reset.

[0024] In addition, a bracket 17 is fixed on the base 1, and the winding roller is rotatably connected to the bracket 17. A horizontally arranged adjusting waist hole 171 is provided on the bracket 17, and a threaded portion 111 extending to the adjusting waist hole 171 is provided on the mounting seat 11. The threaded portion 111 is locked by a nut 200. By adjusting the setting of the waist hole 171, the threaded portion 111 can slide along the direction of the adjusting waist hole 171, thereby adjusting the distance between the contact wheel 14 and the winding roller, thereby realizing fixed-length winding of synthetic leather of different lengths. After moving the threaded portion 111 to a suitable position, the mounting seat 11 can be fixed by screwing in the nut 200 until the nut 200 is tightly pressed against the support plate 2.

[0025] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
