In this case, the counterweight block is fixed by bolts, which is convenient for installation and disassembly of the counterweight block and convenient for use. By increasing or decreasing the number of counterweight blocks, the scribing depth of the blade can be adjusted, and the applicability is wide; the blade is fixed by the second bolt, which is convenient for installation and disassembly of the blade and convenient for use, and the cost of using the blade for film scribing is low; the cost of the blade scribing mechanism is low, and during the film scribing process, there is no need for uniform speed, and the practicability is strong. However, in actual application, the above case cannot quickly scribe the film material on the door panel, and the blade needs to slide back and forth, resulting in a cumbersome film scribing process and affecting work efficiency. Therefore, it is necessary to propose a film scribing device for refrigerator door panels to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a film scribing device for refrigerator door panels, which has the effect of quickly completing the film scribing operation.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A film scribing device for refrigerator door panels includes a workbench. A clamping mechanism for fixing the refrigerator door panel, an adjustable film scribing mechanism, and a lifting structure for connecting the adjustable film scribing mechanism are arranged at the upper end of the workbench. The adjustable film scribing mechanism includes a rectangular frame, three sliding frames, three positioning bolts, and three electric soldering irons. A translation component for connecting the lifting mechanism is arranged at the upper end of the rectangular frame. The three sliding frames are all slidably installed at the bottom of the rectangular frame. A plurality of adjustment holes are equidistantly arranged at the lower end of the rectangular frame. The positioning bolts are inserted into the adjustment holes to fix the sliding frames. The electric soldering irons are installed at the bottoms of the sliding frames.

[0006] By adopting the above technical solutions, the three sliding frames are slid on the rectangular frame, and their positions are adjusted to adapt to the width of the door panel. Then, they are fixed through the cooperation of the positioning bolts and the adjustment holes. Then, the electric soldering irons at the lower end are driven to slide uniformly on the refrigerator door panel through the lifting mechanism and the translation component, so as to complete the film scribing operation on the refrigerator door panel at one time, making the film scribing efficiency higher and the device more applicable.

[0007] A further setting of the present utility model is that the three sliding frames are equidistantly installed at the bottom of the rectangular frame, and the soldering iron is vertically arranged at the bottom of the sliding frame.

[0008] By adopting the above technical solution, the three soldering irons neatly slide across the upper end surface of the refrigerator door panel to neatly cut the film material, facilitating subsequent film tearing.

[0009] A further setting of the present utility model is that the translation component includes a lifting frame connected to the lifting structure. A motor is installed on the outer side of the lifting frame, a unidirectional lead screw is installed at the output end of the motor, limiting rods parallel to both sides of the unidirectional lead screw are installed in the inner cavity of the lifting frame, and a push plate threadedly installed on the outer side of the unidirectional lead screw and slidably connected to the two limiting rods is provided.

[0010] By adopting the above technical solution, the motor drives the unidirectional lead screw to rotate. Under the limitation of the limiting rods on both sides, the push plate is pushed to slide back and forth, thereby controlling the smooth sliding of the soldering iron at the lower end.

[0011] A further setting of the present utility model is that the bottom of the push plate is fixedly connected to the rectangular frame, and the unidirectional lead screw is rotatably arranged in the lifting frame.

[0015] A further setting of the present utility model is that two first guiding rods are vertically installed on the left and right sides of the top of the workbench, and guiding blocks slidably adapted to the first guiding rods are installed on the front and rear sides of the moving plate.

[0016] By adopting the above technical solution, during the sliding process of the moving plate, the guiding blocks slide on the first guiding rods, making the lifting of the moving plate more stable and reliable.

The two clamping brackets are brought closer by the adjusting member, and the door panel is pressed tightly by the pressing member to fix it, facilitating the subsequent stable film scribing operation.

[0019] A further setting of the present utility model is that: the adjusting member includes a bidirectional lead screw rotatably arranged in the workbench, and the two clamping brackets are symmetrically arranged on the bidirectional lead screw and are threadedly connected thereto.

[0020] By adopting the above technical solution, when the bidirectional lead screw is rotated, the clamping brackets on both sides slide relatively under the action of the corresponding thread force, thereby adjusting their spacing to meet the fixation of door panels of different sizes.

[0021] A further setting of the present utility model is that: two second guide rods that are symmetrically arranged front and back are installed in the workbench. The lower end of the clamping bracket is slidably connected to the two second guide rods, and a handle is installed at one end of the bidirectional lead screw extending outside the workbench.

[0022] By adopting the above technical solution, it is convenient to rotate the bidirectional lead screw by holding the handle. Under the sliding limit of the second guide rod, the sliding of the clamping bracket is more stable.

[0023] A further setting of the present utility model is that: the pressing member includes two electric push rods installed on the top of the clamping bracket. A lower pressing plate is installed between the output ends of the two electric push rods, and an anti-slip pad is installed on the lower end surface of the lower pressing plate.

[0024] By adopting the above technical solution, the lower pressing plate is pushed down by the electric push rod, so that the anti-slip pad abuts against the refrigerator door panel, thereby better fixing it on the upper end surface of the workbench.

[0025] The beneficial effects of the present utility model are:

[0026] 1. In the present utility model, by sliding the three sliding brackets on the rectangular frame, adjusting their positions according to the width of the door panel, then fixing them through the cooperation of the positioning bolts and the adjusting holes, and then driving the electric soldering iron at the lower end to slide uniformly across the refrigerator door panel through the lifting mechanism and the translation component, the film scribing operation of the refrigerator door panel is completed at one time, making its film scribing efficiency higher and the device more applicable.

[0027] 2. In the present utility model, by placing the door panel on the workbench, rotating the bidirectional lead screw by holding the handle, the clamping brackets on both sides slide relatively under the action of the corresponding thread force, thereby adjusting their spacing. Then, the lower pressing plate is pushed down by the electric push rod, so that the anti-slip pad abuts against the refrigerator door panel, thereby better fixing it on the upper end surface of the workbench, enabling the device to meet the fixation and film scribing of refrigerator door panels of different sizes, and further improving its applicability.
