Description

Technical Field

[0001] This utility model belongs to the field of cotton placemat processing technology, and specifically relates to a printing device for cotton placemats. Background Technology

[0002] Placemats are tableware made of materials such as cotton, linen, bamboo, paper, plastic, and silicone. They are mainly used to protect tabletops from heat damage, scratches, or oil stains, while also serving as anti-slip and decorative functions.

[0003] During the processing of cotton placemats, it is often necessary to print patterns such as brand logos, product information, or marketing copy on the surface of the placemats.

[0004] Currently, Chinese patent CN203157316U, published on August 28, 2013, discloses a small semi-automatic high-precision screen printing machine. It includes a base supporting the entire instrument, a hollow column serving as the Z-axis on the base table, and a high-lead ball screw erected within the hollow column. A brake motor and a worm gear reducer drive and control the operation of the high-lead ball screw. A crossbeam serving as the X-axis is provided and dynamically engages with the high-lead ball screw, allowing the crossbeam to move up and down. A suction worktable is provided on the base table, and the suction worktable is connected to a high-pressure suction fan. The system is designed to enable vacuum adsorption. A linear guide rail is mounted along the X-axis on the crossbeam. A pair of mesh frame cantilever arms are slidably mounted on the linear guide rail, suspending the mesh frame above the suction worktable. The size of the mesh frame can be easily adjusted by sliding the pair of mesh frame cantilever arms. A doctor blade and ink return blade adjustment device is also mounted on the linear guide rail. A doctor blade device and ink return blade device are mounted at the lower end of the doctor blade and ink return blade adjustment device. A servo motor is configured to drive the doctor blade device and ink return blade device to slide back and forth on the linear guide rail. A PLC control system is also set up to control the operation of the servo motor, brake motor, and worm gear reducer.

[0005] The suction worktable uses negative pressure to firmly fix the printing substrates such as paper, film, and metal onto the printing platform, preventing displacement during printing and ensuring accurate pattern positioning. However, when the suction worktable is used to place cotton placemats, the negative pressure adsorption is not ideal for positioning the cotton placemats because they are breathable, which makes it difficult for the cotton placemats to be placed stably on the printing platform. Utility Model Content

[0006] The purpose of this invention is to provide a printing device for cotton placemats, which can stably position the cotton placemats.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a printing device for cotton placemats, including a base of a screen printing machine, a printing table disposed on the upper side of the base for placing cotton placemats, a column disposed on the upper side of the base, a horizontal plate slidably connected to the column, a screen arm slidably connected to the end position of the horizontal plate, a printing screen held between two screen arms, a movable arm slidably connected to the horizontal plate, and two movably connected to the movable arm. A pressure plate is detachably connected to the printing table, and a Velcro hook-and-loop fabric is disposed between the pressure plate and the printing table. A through hole with an shape matching the shape of the cotton placemat is opened at the center of the pressure plate. A placement platform for supporting the cotton placemat is disposed in the through hole. An annular groove for the side of the cotton placemat to be embedded is left between the placement platform and the through hole. A connecting rod connected to the inner wall of the through hole is disposed on the periphery of the placement platform. When the cotton placemat is laid on the placement platform, the side of the cotton placemat passes through the annular groove and is bonded to the surface of the Velcro hook-and-loop fabric.

[0008] A further feature of this invention is that: two connecting ears are provided on both sides of the pressure plate, and connecting holes are provided on the connecting ears; threaded holes corresponding to the positions of the connecting holes are provided on the side of the printing table; and a threaded shaft is provided on the connecting ear that passes through the connecting hole and is threaded into the threaded hole.

[0009] A further feature of this invention is that a striped knob is provided at the end of the threaded shaft.

[0010] A further feature of this invention is that a storage groove for storing Velcro hook fabric is provided on the lower surface of the pressure plate.

[0011] A further feature of this invention is that the connecting rod is located at the lower part of the side of the placement platform.

[0012] A further feature of this invention is that the periphery of the Velcro hook fabric is provided with a flexible magnetic strip for attracting onto the pressure plate.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. When printing is required on the surface of the cotton placemat, the pressure plate is connected to the printing table, and the Velcro hook fabric is located between the pressure plate and the printing table. The operator lays the cotton placemat on the placement table inside the through hole, and then presses the side of the cotton placemat into the ring groove and sticks it to the surface of the Velcro hook fabric. At this time, the position of the cotton placemat on the pressure plate can be positioned by the Velcro hook fabric. Then, the printing operation can be performed on the surface of the cotton placemat using a squeegee and a printing screen, and finally, the cotton placemat can be stably positioned.

[0015] Meanwhile, once a cotton placemat is printed, the operator can pull out the side of the cotton placemat from the ring groove to remove it from the pressure plate, which will facilitate the quick loading and unloading of the cotton placemat on the pressure plate.

[0016] 2. When the pressure plate is installed on the printing table, the threaded shaft passes through the connecting hole on the connecting ear and is threaded into the threaded hole, which allows for easy installation and removal of the pressure plate on the printing table. When printing is not required on cotton placemats but on ordinary paper, film, metal and other substrates, simply unscrew the threaded shaft to remove the pressure plate and Velcro hook fabric, allowing the substrate to be placed on the smooth printing table alone.

[0017] 3. The threaded shaft can be easily rotated manually using the striped knob at the end of the threaded shaft;

[0018] 4. The pressure plate uses a storage groove on its lower surface to store the hook and loop fabric, thus preventing the hook and loop fabric from affecting the level of the pressure plate surface;

[0019] 5. By positioning the connecting rod at the lower part of the side of the placement table, the impact of the connecting rod on the side of the cotton placemat being embedded in the annular groove is reduced;

[0020] 6. The hook and loop fastener fabric uses flexible magnetic strips to attach to the lower surface of the pressure plate, which facilitates the quick installation of the hook and loop fastener fabric on the lower surface of the pressure plate. Attached Figure Description
