Description

Technical Field

[0001] This utility model belongs to the field of synthetic leather production equipment, and in particular relates to a base fabric printing device for synthetic leather production. Background Technology

[0002] Synthetic leather is a polymer composite material that simulates the properties of natural leather through artificial synthesis technology. It is usually composed of a base fabric (support layer) and a coating (functional layer).

[0003] The base fabrics of existing synthetic leathers are mainly non-woven fabrics and knitted or woven fabrics. In the manufacturing of synthetic leather, due to the high extensibility of the base fabric, it is often split in the middle and then stretched and stacked to form the required base fabric.

[0004] The existing base fabric cutting is mainly achieved by automatically cutting the base fabric while it is moving. In order to ensure the accuracy of the cutting, workers often need to observe on-site. However, since the base fabric is basically white, workers need to pay close attention to observe during the movement of the base fabric to avoid cutting errors and waste. Utility Model Content

[0005] This invention addresses the technical problem of difficulty in observing the cutting of existing base fabrics by proposing a base fabric printing device for synthetic leather production that is reasonably designed, simple in structure, easy to process, and can effectively facilitate observation by workers.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a base fabric printing device for synthetic leather production, including a frame and a transfer wheel rotatably mounted on the frame. A pigment tank is provided below the transfer wheel, and the bottom of the transfer wheel extends into the pigment tank. An annular groove is provided in the middle of the circumferential surface of the transfer wheel. An auxiliary frame is provided at the front end of the frame, and a support wheel is provided on the auxiliary frame. The support wheel can be flipped to the front end of the transfer wheel. An auxiliary groove is provided in the middle of the circumferential surface of the support wheel. The auxiliary groove is annular, and its width is greater than the width of the transfer wheel. The front end of the transfer wheel extends into the auxiliary groove.

[0007] Preferably, a drive motor is provided at the bottom of the pigment tank, the power end of the drive motor extends into the pigment tank, and a stirring blade is fitted onto the end of the drive motor that extends into the pigment tank.

[0008] Preferably, connecting arms are provided on both sides of the support wheel, and a rotating shaft is provided at the end of the connecting arm away from the support wheel. A bearing seat for mounting the rotating shaft is provided on the auxiliary frame. One end of the rotating shaft extends out of the bearing seat and is connected to a drive arm. A drive cylinder is also hinged on the auxiliary frame, and the power end of the drive cylinder is hinged to the drive arm.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model provides a base fabric printing device for synthetic leather production. By setting up a transfer roller, the transfer roller with pigment is used to print and dye the middle part of the base fabric with the cooperation of the support roller. The middle gap formed by printing and dyeing is the cutting gap.

[0012] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0013] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0014] Example 1, such as Figures 1-3 As shown, this embodiment aims to solve the problem that it is inconvenient to observe whether the cutting is in the middle of the base fabric. Considering that marking the middle of the base fabric can solve this problem, this embodiment is proposed to cooperate with cutting equipment and other equipment to achieve automated marking.

[0015] To achieve the above objectives, the synthetic leather production base fabric printing equipment provided in this embodiment includes a frame 1 and a transfer wheel 11 rotatably mounted on the frame 1. The transfer wheel 11 is generally vertically cylindrical, with a rotating shaft 12 disposed in its middle. The transfer wheel 11 is mounted on the frame 1 via the rotating shaft 12. A meshing gear 13 is fitted at one end of the rotating shaft 12. A rotating motor 15 is also mounted on the frame 1. A drive gear 14 is fitted at the power end of the rotating motor 15. The drive gear 14 meshes with the meshing gear 13 to drive the transfer wheel 11.

[0016] To mark the base fabric, a pigment tank 2 is provided below the transfer wheel 11. The pigment tank 2 is filled with pigment. There are several ways to place the pigment in the pigment tank 2. It can be replenished by manual addition. In this embodiment, a feed pipe 21 is provided on one side of the pigment tank 2. The feed pipe 21 is connected to a pigment tank. A valve is installed on the pipe connecting the two. Since the pigment is consumed slowly, it can be replenished by continuously dripping pigment through a slightly open valve. Alternatively, it can be replenished by setting a liquid level valve.

[0017] To ensure that the ink can contact the transfer wheel 11, the bottom of the transfer wheel 11 extends into the ink tank 2. In this way, the rotation of the transfer wheel 11 will carry away the ink. For easy observation, an annular groove 111 is provided in the middle of the circumferential surface of the transfer wheel 11. The annular groove 111 makes the two sides of the circumferential surface of the transfer wheel 11 protrude. During printing, two spaced rectangular lines are formed, and the area between the two rectangular lines is the cutting area.

[0018] To facilitate printing and dyeing, an auxiliary frame 3 is provided at the front end of the machine frame 1. A support wheel 31 is mounted on the auxiliary frame 3. The support wheel 31 can be flipped to the front end of the transfer wheel 11. An auxiliary groove 311 is provided in the center of the circumference of the support wheel 31. Like the annular groove 111, the auxiliary groove 311 is annular, and its width is greater than the width of the transfer wheel 11. The front end of the transfer wheel 11 extends into the auxiliary groove 311. This reduces the gap between the two, ensuring that the printing and dyeing can be performed on the base fabric. In use, the base fabric is passed between the machine frame 1 and the auxiliary frame 3, ensuring that the center of the base fabric is positioned at the transfer wheel 11. Then, the support wheel 31 is controlled to make the base fabric adhere to it, thereby allowing it to contact the transfer wheel 11 and complete the printing and dyeing process.

[0019] To facilitate the control of the rotation of the support wheel 31, connecting arms 32 are provided on both sides of the support wheel 31. The support wheel 31 can be rotatably mounted on the connecting arms 32 or it can remain stationary. Its main function is to provide support and guidance. A rotating shaft 33 is provided at the end of the connecting arm 32 away from the support wheel 31. The rotating shaft 33 passes through the two connecting arms 32. A bearing seat 34 for mounting the rotating shaft 33 is provided on the auxiliary frame 3. Of course, a bearing is installed on the bearing seat 34. In this way, the support wheel 31 can rotate around the rotating shaft 33.

[0020] To control the rotation of the rotating shaft 33, one end of the rotating shaft 33 extends out of the bearing housing 34. A drive arm 35 is connected to the end of the rotating shaft 33 extending out of the bearing housing 34. The drive arm 35 is a straight rod, and a drive cylinder 36 is also hinged to the auxiliary frame 3. The power end of the drive cylinder 36 is hinged to the drive arm 35. In this way, the extension and retraction of the power end of the drive cylinder 36 can control the reciprocating rotation of the support wheel 31.

[0021] Considering that the pigment is a liquid material, it will settle to some extent. Therefore, a drive motor 4 is installed at the bottom of the pigment tank 2. The power end of the drive motor 4 extends into the pigment tank 2, and a stirring blade 41 is fitted onto the end of the drive motor 4 that extends into the pigment tank 2. It should be noted that the rotation speed of the drive motor 4 should not be too fast, and should be controlled at 60 revolutions / min to prevent sedimentation. Of course, a corresponding stirring mechanism should also be added to the pigment tank. If the pigment is added manually, it needs to be stirred manually when removing the pigment.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
