[0050] In some embodiments, the preparation process of making synthetic leather is: evenly coating the slurry on the release paper; then drying the release paper coated with the slurry and bonding it to the synthetic leather base, and finally peeling the synthetic leather with the release paper to obtain a finished synthetic leather. The drying process needs to ensure that the material is spread out flat, and ensure that the coated slurry can be evenly attached to the synthetic leather base after drying, so it is spread flat on a plane for drying.

[0051] The existing market demand exists for synthetic leather materials of two different widths, one of which is about 1.4m and the other is about 2.1m. Therefore, it is necessary to purchase two or more sets of production equipment for drying to produce synthetic leathers of different widths. This has a high production cost and occupies more workshop space. Therefore, it is expected that there will be production equipment that can meet the production needs of different widths.

[0052] Therefore, the utility model provides a synthetic leather production equipment with adjustable width, which is used for production processes in synthetic leather production that require flat placement, such as coating processes, laminating processes, and especially drying processes. The width can be flexibly adjusted to adapt to the production of synthetic leathers of various widths, thereby reducing the cost of production equipment, reducing the occupied area of ​​production equipment, saving energy, and improving efficiency.

[0053] See also Figure 1 ,and Figure 2 In a specific embodiment, the adjustable width synthetic leather production equipment includes a first workbench, which includes a fixed part and a movable part; the fixed part includes a support leg 1 and a support platform 2; the movable part includes a horizontal moving device 3, a movable support member 4 and a movable platform 5, the horizontal moving device 3 is used to move the movable support member 4 and the movable platform 5 in a horizontal direction, the movable support member 4 is used to support the movable platform 5, and a vertical moving device 400 is also provided on the movable support member 4.

[0054] The movable platform 5 of the movable part is horizontally moved by the horizontal moving device 3, so it can be moved to the bottom of the support platform 2 of the fixed part, or to the side of the support platform 2 of the fixed part. The movable platform 5 of the movable part is vertically moved by the vertical moving device 400, so it can be moved to a support platform 2 higher than the fixed part, or to a support platform 2 lower than the fixed part. Therefore, when it is necessary to dry materials with a larger width, the movable part can expand the width of the fixed part to increase the overall width of the first workbench to adapt to the width of the material to be dried at this time. When it is necessary to dry materials with a smaller width, the movable part can be retracted to the bottom of the support platform 2 of the fixed part to reduce the width of the first workbench to adapt to the width of the material to be dried at this time, and reduce the floor area of ​​the first workbench, and is conducive to flexibly changing the size of the drying space to save energy and improve efficiency.

[0055] Therefore, the utility model has the function of flexibly adjusting the width to adapt to the production of synthetic leathers of various widths, which can reduce the cost of production equipment to a greater extent, reduce the occupied area of ​​production equipment, save energy, and improve efficiency.

[0056] The lateral width of the first workbench is the width orthogonal to the conveying direction when the synthetic leather is made, the longitudinal length of the first workbench is the length of the conveying direction when the synthetic leather is made, and the direction in which the movable part expands to the fixed part is the direction of the lateral width of the first workbench, so as to adapt to the width of the release paper. During the production process, the coating process will last for a certain period of time, that is, the release paper to be dried has a certain length. In order to dry a longer release paper, in some embodiments, the first workbench is provided with a plurality of movable parts, which are arranged at intervals in a direction parallel to the production line, or can be compactly spliced ​​in the conveying direction when the synthetic leather is made, so as to increase the longitudinal length of the entire adjustable width synthetic leather production equipment. In other embodiments, the first workbench includes a fixed part, and a plurality of movable parts, and the movable parts are arranged at intervals or compactly in a direction parallel to the production line. Since the material has a certain strength, the movable parts are arranged at intervals. Even in the position where the movable part is not arranged, the material exceeding the width of the fixed part can be kept tight due to its own tension. It is only necessary to adjust the specific interval according to the actual situation.

[0057] The supporting legs 1 can be provided with a plurality of them according to the actual area of ​​the supporting platform 2. For example, if the area of ​​the supporting platform 2 is not particularly large, a supporting leg 1 is respectively provided at the four corners of the supporting platform 2. If the area of ​​the supporting platform 2 is relatively large, a plurality of supporting legs 1 can also be provided at the middle position of the supporting platform 2 for greater stability. The movable supporting member 4 of the movable part can also be provided in the same manner.

[0058] In some embodiments, the first working station includes a first working state and a second working state. Figure 1 or Figure 3 As shown, in the first working state, the horizontal moving device 3 is in the folded position, that is, the movable platform 5 is folded in the space under the supporting platform 2 by the horizontal moving device 3, and the vertical moving device 400 is in the low position, that is, the movable platform 5 is at a height lower than the supporting platform 2 by the vertical moving device 400, and the movable platform 5 is located below the supporting platform 2; in the second working state, as Figure 4 As shown, the horizontal moving device 3 is in the extended position, that is, the movable platform 5 is extended out of the space below the supporting platform 2 by the horizontal moving device 3, as shown in FIG. Figure 5 and Figure 6 As shown, the vertical moving device 400 is in a high position, that is, the movable platform 5 is placed at a height flush with the support platform 2 through the vertical moving device 400 , and the movable platform 5 is located outside the support platform 2 in the horizontal direction.

[0059] The structure of the horizontal moving device 3 can be various, such as Figure 1As shown, in a further embodiment, the horizontal moving device 3 may include a linear slide rail, which is arranged along the lateral width of the support platform 2, with a portion located below the support platform 2 and another portion extending outward. The movable support member 4 is arranged at the linear slide rail so as to be movable along the linear slide rail.

[0060] The linear slide rail may be provided with a slider, and the movable support 4 is connected to the slider. When in the first working state, the slider is located below the support platform 2, that is, the horizontal moving device 3 is in a retracted position. When in the second working state, the slider is located outside the support platform 2, that is, the horizontal moving device 3 is in an extended position.

[0061] The movable part can be moved by manpower to switch from the first working state to the second working state, or from the second working state to the first working state, such as directly pulling the movable platform 5, or the slider is bolted and connected to a screw rod, and a rocker is provided at the end of the screw rod, and the screw rod is rotated by the rocker rod to drive the slider to move; it can also be driven by a power device, such as when the horizontal moving device 3 includes a linear slide rail and a slider, the power device can be a cylinder, an oil cylinder or a drive motor 300, such as Figure 2 or Figure 6 As shown, if it is a driving motor 300, it can be set as a screw motor, and the screw of the screw motor is threadedly connected to the slider to drive the slider to move.

[0062] In another embodiment, the horizontal moving device 3 can also be a moving wheel disposed at the bottom of the movable support 4, and the rotating shaft of the moving wheel is parallel to the longitudinal length direction of the support platform 2, so as to realize the horizontal movement of the movable platform 5, that is, to move along the lateral width direction of the support platform 2. In addition, similarly, the horizontal moving device 3 also includes a linear slide rail, and the moving wheel is disposed in the linear slide rail, and the moving direction of the moving wheel can be limited by the linear slide rail.

[0063] The movable part can be moved by manpower to switch from the first working state to the second working state, or from the second working state to the first working state, or can be driven by a power device. For example, when the horizontal moving device 3 includes a linear slide rail and a moving wheel, the power device can be a rotating motor, which is connected to the rotating shaft of the moving wheel to drive the moving wheel to rotate, thereby driving the entire movable part to move horizontally.

[0064] The vertical moving device 400 may include a telescopic column, which is coaxially arranged with the movable support 4. By adjusting the length of the telescopic column, the height of the movable platform 5 is adjusted. Similarly, the length of the telescopic column can be adjusted by manpower, or it can be driven by a power device, such as a linear motor, a cylinder or an oil cylinder, which can be arranged at the bottom of the telescopic column, and the output end of the linear motor, cylinder or oil cylinder is connected to the top of the telescopic column. By driving the length of the telescopic column by the power device, it is more labor-saving, and the height of the movable platform 5 can be accurately adjusted to be flush with the support platform 2 or lower than the height of the support platform 2.

[0065] In another embodiment, the vertical moving device 400 is directly a linear motor, a cylinder or an oil cylinder. For example, the linear motor, the cylinder or the oil cylinder is arranged on the movable support 4, and the output end of the linear motor, the cylinder or the oil cylinder is connected to the bottom surface of the movable platform 5.

[0066] In one embodiment, the horizontal moving device 3 and the vertical moving device 400 are both driven by a power device, and in some embodiments, an electric control device is further included, and the electric control device is used to control the movement of the horizontal moving device 3 or the vertical moving device 400. If the electric control device is connected to each power device, each power device is driven respectively to achieve the purpose of controlling the movement of the horizontal moving device 3 or the vertical moving device 400, and by presetting a value for the electric control device, the electric control device is relied on to switch from the first working state to the second working state, or from the second working state to the first working state.

[0067] In order to make the movable platform 5 move more smoothly, in some embodiments, a track 200 is further provided under the support platform 2 , and the track 200 is used to limit the moving direction of the movable platform 5 .

[0068] The slide rails may be provided with two, both of which are parallel to the lateral width of the support platform 2 and are arranged side by side, and the slide grooves of the two slide rails are arranged opposite to each other. When the movable platform 5 moves to the bottom of the support platform 2, the two ends of the movable platform 5 are respectively embedded in the slide grooves of the two slide rails, thereby achieving the purpose of limiting the moving direction of the movable platform 5.

[0069] In order to assist the movable platform 5 to move and avoid excessive friction causing wear of the movable platform 5, Figure 2 , Figure 4 As shown, in some embodiments, a pulley 500 is installed on the side wall or the bottom wall of the movable platform 5. When the movable platform 5 moves to the bottom of the supporting platform 2, the pulley 500 is embedded in the slide groove of the slide rail, thereby making the movement of the movable platform 5 smoother and more labor-saving.

[0070] In one embodiment, a support foot 1 is provided at each of the four corners of the support platform 2. In order to allow the movable portion to be folded under the support platform 2 of the fixed portion, the longitudinal length of the movable platform 5 of the movable portion can be set to be slightly smaller than the longitudinal length of the support plane of the fixed portion, specifically smaller than the spacing between the two support feet 1 of the support platform 2 in the longitudinal length direction, so that the support feet 1 of the fixed portion will not affect the entry and exit of the movable platform 5 under the support platform 2. The specific data of the transverse width of the movable platform 5 of the movable portion can be set according to actual needs.

[0071] In one embodiment, the longitudinal length of the movable platform 5 of the movable part is set to be slightly smaller than the longitudinal length of the supporting plane of the fixed part. In order to enable the ends of several first workbenches to be seamlessly spliced, the ends of the movable platform 5 can be respectively provided with docking plates. In one embodiment, the docking plate can be folded into a storage groove provided at the end face of the movable platform 5. When it is needed, the docking plate is pulled out along the longitudinal length direction of the movable platform 5 until it is flush with the end face of the support platform 2, so that the ends of the movable platforms 5 of the front and rear first workbenches are seamlessly spliced; in another embodiment, the docking plate can also be hinged to the movable part, and the docking plate and the movable part are connected by a hinge with damping. When the movable part is folded under the support platform 2, the docking plate is folded on the support platform 2. When the movable part moves to one side of the support platform 2, the docking plate is folded 180 degrees until it is flush with the support platform 2.

[0072] When the first workbench is used as a conveying mechanism, a plurality of rollers are arranged on the fixed part, a horizontally arranged roller is arranged at the axis of the roller, and the two ends of the roller are respectively inserted into the two side plates of the fixed part. A plurality of rotating drums are also arranged on the movable part, a horizontally arranged movable rotating drum is arranged at the axis of the rotating drum, and the two ends of the movable rotating drum are respectively inserted into the two side plates of the movable part. When the movable part is adjusted to the second working state, one end of the movable rotating roller is fixed to one end of the rotating roller. The diameters of the roller and the rotating drum are set to be the same, so that the upper surfaces of the fixed part and the movable part can maintain the same rotation speed. In some further specific embodiments, one end of the movable rotating roller and one end of the rotating roller are respectively provided with a plug jack, and the two are fixed by plugging, or they can be respectively provided with a card slot, and the two are fixed by card connection. In this way, only one driving mechanism needs to be set on one side of the fixed part to drive the rotating roller, so that the roller and the rotating drum can be driven at the same time.

[0073] In some embodiments, the synthetic leather production equipment with adjustable width further includes a box 6, which is arranged outside the first workbench, and the first workbench is placed in the box 6 and can be used for drying operations, that is, a drying space is provided. In a further embodiment, a drying device is provided in the box 6, such as a dryer 7 is provided above the box 6, and the dryer 7 can increase the temperature in the box 6, reduce the humidity in the box 6, and dry the release paper in the box 6, so that the entire synthetic leather production equipment with adjustable width becomes a drying box.

[0074] When it is necessary to dry materials with a smaller width, the movable part will be retracted under the support platform 2, and the space in the box 6 for the movable part to move to the second working state will be vacated. In order to reduce energy waste and improve drying efficiency, in a further embodiment, the inner wall of the box 6 is provided with an air curtain 600, and the upper end of the air curtain 600 is connected to the rolling curtain device 601. The air curtain 600 can be rolled into the rolling curtain device 601, and can also be released from the rolling curtain device 601. Specifically, the rolling curtain is arranged above one side of the support platform 2 of the fixed part, such as Figure 3 As shown, when the roller curtain is lowered, the space in the box body 6 is divided into two parts, namely the space where the fixed part is located, and the space in the box body 6 for the movable part to move to the second working state. The air inlet of the fan can be set on the side where the fixed part of the drying equipment is located. When the hot air hits the wind curtain 600 during flow, it will be blocked. In this way, the fan only needs to operate in the space where the fixed part is located, which reduces energy waste and improves drying efficiency. Figure 5 As shown, when it is necessary to dry a wider material, the air curtain 600 is rolled up and the movable part is moved to the second working state, which does not affect the drying of the wider synthetic leather material.

[0075] In order to improve the sealing performance, in some embodiments, a pendant is provided at the lower end of the air curtain 600. The wind curtain 600 can be straightened by the deadweight effect of the pendant and can also be prevented from being blown up by the wind curtain 600. In embodiments where the height of the air curtain 600 is appropriate, it can also be ensured that the bottom of the air curtain 600 is in close contact with the ground (such as the bottom surface of the box 6) to achieve the technical effect of reducing air leakage.

[0076] In a further embodiment, the pendant includes a magnetic member 602, and the magnetic member 602 is used to be adsorbed at a preset position. For example, a magnetic strip with magnetic force is provided on the floor of the box 6, and the position where the magnetic strip is provided is the preset position. When the air curtain 600 is lowered, the magnetic member 602 is adsorbed at the magnetic strip, thereby ensuring that the bottom of the air curtain 600 is in close contact with the floor of the box 6. Finally, the technical effect of reducing air leakage is achieved.

[0077] 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.
