Description

Technical Field

[0001] This utility model relates to a peeling device, specifically a polyurethane synthetic leather surface peeling device, belonging to the field of synthetic leather production technology. Background Technology

[0002] Polyurethane synthetic leather belongs to a type of polyurethane elastomer. It has a soft, natural luster, a soft feel, and a strong leather-like appearance. It also has excellent mechanical properties such as good adhesion to the substrate, wear resistance, flexural resistance, and aging resistance. The industrial production methods of polyurethane synthetic leather are mainly divided into two categories: dry process and wet process. The dry process generally uses release paper as a carrier. Polyurethane resin slurry is coated onto the release paper (usually one or two times), and then placed in an oven to heat and dry to remove the solvent in the resin, forming a continuous and uniform polyurethane film. Then, an adhesive is coated onto the film and bonded to the base fabric. After drying and curing, the release paper is peeled off using a peeling device, and the finished artificial leather and release paper are rolled separately.

[0003] A search revealed an existing patent number: 202211020721.X, which describes a polyurethane synthetic leather surface peeling device. This device, through the coordinated use of a telescopic peeling mechanism and an auxiliary peeling mechanism, can efficiently and quickly peel release paper from synthetic leather. During peeling, the auxiliary roller in the auxiliary peeling mechanism, in conjunction with a telescopic rotating frame, gears, and racks, can rotate and extend using the power output of an electric telescopic rod. This allows the auxiliary roller to maintain tension on the raw material during peeling and move stably toward the telescopic peeling mechanism. The telescopic peeling mechanism utilizes a telescopic and opening / closing frame to efficiently and quickly peel the release paper from the synthetic leather.

[0004] However, this patent lacks a heating component when peeling the fabric. If the adhesive is not heated and softened before peeling, it will affect the peeling effect and easily damage the fabric. At the same time, it lacks a buffer component when placing the rolled material. When the rolled fabric sticks and gets stuck during release, it cannot buffer the release of tension. If it is pulled directly, it is easy to break the fabric, which will affect subsequent production.

[0005] Therefore, how to design a component that separates after the adhesive has softened and releases the tension to prevent breakage has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] The purpose of this invention is to provide a polyurethane synthetic leather surface peeling device to solve the above problems. By installing two high-temperature resistant heat-insulating covers, the fabric is heated on both sides to soften the adhesive, which facilitates the subsequent peeling work. At the same time, the combination of compression spring and slider prevents the fabric from being pulled apart and damaged due to jamming on the feeding roller.

[0007] The present utility model realizes the above object through the following technical solutions. A surface peeling device for polyurethane synthetic leather includes a mounting plate, on which a heating mechanism is installed. The heating mechanism includes a high-temperature resistant heat accumulation cover. Two symmetric high-temperature resistant heat accumulation covers are installed inside the mounting plate. An electric heating wire is installed inside the high-temperature resistant heat accumulation cover. A feeding mechanism is installed at one end of the mounting plate. The feeding mechanism includes a support plate. The support plate is installed outside one end of the mounting plate. One end of the support plate is slidably connected to a slider through a guide groove. A compression spring is connected between the slider and the inside of the guide groove. One end of the slider extends outside the support plate, and a feeding roller is installed at one end of the slider.

[0008] Preferably, the sides of the two high-temperature resistant heat accumulation covers are trapezoidal structures, and a metal protection net is installed on the opposite sides of the two high-temperature resistant heat accumulation covers.

[0009] Preferably, guide blocks are respectively installed at both ends of the two high-temperature resistant heat accumulation covers. The guide blocks are slidably connected to the side wall of the mounting plate, and the high-temperature resistant heat accumulation cover is slidably connected to the inside of the mounting plate through the two guide blocks.

[0010] Preferably, a fixing block is fixedly connected to the outer wall of the mounting plate. A reverse threaded rod is rotatably connected to the fixing block. The guide blocks at one end of the two high-temperature resistant heat accumulation covers respectively extend outside the mounting plate and are threadedly connected to both ends of the reverse threaded rod.

[0011] Preferably, the reverse threaded rod is a "T" - shaped structure, and a turning knob is installed at the top of the reverse threaded rod.

[0012] Preferably, the guide groove and the slider are both "convex" - shaped structures, and the feeding roller is a cylindrical "T" - shaped structure.

[0013] Preferably, a dust cover is slidably connected inside the guide groove. One end of the dust cover is connected to the slider, and the other end of the dust cover is connected to the inner wall of the end of the guide groove.

[0014] Preferably, a clamping groove is provided on one side of the mounting plate. The other end side wall of the support plate is detachably clamped inside the clamping groove, and the clamping groove is a "convex" - shaped structure.

[0015] Preferably, an adjusting mechanism is installed on the support plate. The adjusting mechanism includes a screw rod. The screw rod is threadedly connected to the inside of the other end of the support plate. One end of the screw rod extends outside the support plate, and the other end of the screw rod extends inside the guide groove. A push block is slidably connected inside the guide groove. One side of the push block is connected to the compression spring, and the other side of the push block is rotatably connected to the end of the screw rod.

[0016] Preferably, a positioning rod is installed at the center of one side of the push block, and one end of the compression spring is clamped outside the positioning rod.

[0017] The beneficial effects of this utility model are as follows: the installation of the mounting plate enables the peeling of the fabric. The combination of symmetrical high-temperature heat-insulating covers and electric heating wires facilitates the heating of both sides of the fabric as it passes between the two high-temperature heat-insulating covers, thereby softening the adhesive on the fabric and achieving better peeling. At the same time, the installation of the support plate facilitates the support of the feeding roller and makes it easier to place the material roll. The slider, in cooperation with the compression spring, can slide telescopically inside the guide groove. When the fabric gets stuck during peeling, the fabric is tightened. At this time, the fabric will drive the winding drum on the feeding roller to move. The feeding roller drives the slider to slide away from the elastic force of the compression spring, which plays a buffering role and prevents the fabric from breaking. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5As shown, a polyurethane synthetic leather surface peeling device includes a mounting plate 1, on which a heating mechanism 2 is mounted. The heating mechanism 2 includes a high-temperature resistant heat shield 201. Two symmetrical high-temperature resistant heat shields 201 are installed inside the mounting plate 1. An electric heating wire 207 is installed inside the high-temperature resistant heat shield 201. A feeding mechanism 3 is mounted at one end of the mounting plate 1. The feeding mechanism 3 includes a support plate 301. The support plate 301 is mounted on the outer side of one end of the mounting plate 1. A slider 306 is slidably connected to the inner side of one end of the support plate 301 through a guide groove 307. The slider 306 is connected to the inside of the guide groove 307 through a compression spring 305. One end of the slider 306 extends to the outer side of the support plate 301. A feeding roller 302 is mounted on one end of the slider 306.

[0026] As a technical optimization of this utility model, the two high-temperature heat-concentrating covers 201 have trapezoidal side structures, and metal protective nets 206 are installed on opposite sides of the two high-temperature heat-concentrating covers 201. The installation of the metal protective nets 206 plays a role in shielding and protecting, and the trapezoidal structure design of the high-temperature heat-concentrating covers 201 allows heat to diffuse evenly to the outside.

[0027] As a technical optimization of this utility model, guide blocks 204 are respectively installed at both ends of the two high-temperature heat-resistant covers 201. The guide blocks 204 are slidably connected to the side wall of the mounting plate 1. The high-temperature heat-resistant covers 201 are slidably connected to the inside of the mounting plate 1 through the two guide blocks 204. By sliding the two guide blocks 204 against the side wall of the mounting plate 1, it is convenient to adjust the position of the high-temperature heat-resistant covers 201, so as to achieve more uniform heating and softening of the adhesive.

[0028] As a technical optimization of this utility model, a fixing block 202 is fixedly connected to the outer wall of the mounting plate 1, and a reverse threaded rod 203 is rotatably connected to the fixing block 202. The guide blocks 204 at one end of the two high-temperature heat-concentrating covers 201 extend to the outside of the mounting plate 1 and are threadedly connected to both ends of the reverse threaded rod 203. The installation of the fixing block 202 facilitates the connection of the reverse threaded rod 203. The connection of the two guide blocks 204 with the reverse threaded rod 203 ensures the stable installation of the high-temperature heat-concentrating cover 201. By rotating the reverse threaded rod 203, the two guide blocks 204 can move closer or further away from each other, thereby achieving synchronous adjustment of the position of the two high-temperature heat-concentrating covers 201, which is convenient for adjusting the appropriate position when heating fabrics of different thicknesses.

[0029] As a technical optimization of this utility model, the reverse threaded rod 203 has a "T" shaped structure, and a rotating torque 205 is installed on the top of the reverse threaded rod 203, which is beneficial to prevent the guide block 204 from slipping off the reverse threaded rod 203, and facilitates good driving control of the reverse threaded rod 203 through the rotating torque 205.

[0030] As a technical optimization of this utility model, the guide groove 307 and the slider 306 are both "convex" shaped structures, and the feeding roller 302 is a cylindrical "T" shaped structure. This facilitates the smooth sliding of the slider 306 and the inside of the guide groove 307 without falling off, and prevents the winding drum from rubbing against the slider 306 after it is fitted with the feeding roller 302, thus playing a blocking and positioning role.

[0031] As a technical optimization of this utility model, a dust cover 304 is slidably connected inside the guide groove 307. One end of the dust cover 304 is connected to the slider 306, and the other end of the dust cover 304 is connected to the inner wall of the end of the guide groove 307. The installation of the dust cover 304 helps to shield and protect the inside of the guide groove 307, preventing debris from entering and causing the slider 306 to jam.

[0032] As a technical optimization of this utility model, the mounting plate 1 is provided with a slot 303 on one side, and the side wall of the other end of the support plate 301 is detachably engaged with the inside of the slot 303. The slot 303 has a "convex" shaped structure, which facilitates the detachable maintenance of the support plate 301 and the mounting plate 1 and makes it easy to replace later.

[0033] As a technical optimization of this utility model, an adjustment mechanism 4 is installed on the support plate 301. The adjustment mechanism 4 includes a screw 401. The screw 401 is internally threaded to the other end of the support plate 301. One end of the screw 401 extends to the outside of the support plate 301, and the other end extends into the guide groove 307. A push block 402 is slidably connected inside the guide groove 307. One side of the push block 402 is connected to a compression spring 305, and the other side of the push block 402 is rotatably connected to the end of the screw 401. The threaded installation of the screw 401 and the support plate 301 facilitates the driving control of the push block 402, thereby adjusting the resistance force of the push block 402 against the compression spring 305 and facilitating the elasticity adjustment of the compression spring 305.

[0034] As a technical optimization of this utility model, a positioning rod 403 is installed at the center of one side of the push block 402, and one end of the compression spring 305 is engaged with the outer side of the positioning rod 403. The installation of the positioning rod 403 facilitates the positioning of the compression spring 305 and prevents the compression spring 305 from slipping off the push block 402.

[0035] In use, this invention first involves symmetrically installing two high-temperature resistant heat-concentrating covers 201 inside the mounting plate 1. Then, a support plate 301 is connected to one side of the mounting plate 1 via a slot 303. A fabric roll is connected to a feeding roller 302, and the rolled fabric on the feeding roller 302 is guided into the mounting plate 1 for peeling. Simultaneously, the fabric passes between the two high-temperature resistant heat-concentrating covers 201. Rotating the knob 205 causes the reverse threaded rod 203 to control the two guide blocks 204 to move closer or further away, positioning the two high-temperature resistant heat-concentrating covers 201 at appropriate positions on both sides of the fabric. Since an electric heating wire 207 is installed inside the high-temperature resistant heat-concentrating cover 201, and the electric heating wire 207 is electrically connected to an external power source, heat is emitted through the high-temperature resistant heat-concentrating cover 201 and dissipated through the two high-temperature resistant heat-concentrating covers 201. 1. Heat is introduced to both sides of the fabric for heating, thereby softening the adhesive on the fabric. The fabric is peeled off by the operation of the mounting plate 1. A compression spring 305 is installed inside the support plate 301. The slider 306 can slide telescopically inside the guide groove 307 in cooperation with the compression spring 305. When the fabric gets stuck during peeling, the fabric is tightened. At this time, the fabric will drive the winding drum on the feeding roller 302 to move. The feeding roller 302 drives the slider 306 to get rid of the elastic force of the compression spring 305, which plays a buffering role and prevents the fabric from breaking. By rotating the screw 401, the resistance force of the push block 402 against the compression spring 305 can be adjusted, which is conducive to adjusting the elastic force of the compression spring 305 according to the tensile strength of the fabric, so as to achieve both good feeding and prevention of breakage.
