[0002] Vacuum forming machine, also known as thermoplastic forming machine, is a plastic processing equipment, the main function of which is to process thermoplastic plastic sheets into products of various shapes;

[0003] After the production operation, traditional blister forming machines mostly use manual unloading and negative pressure adsorption to unload materials. Although the unloading operation of molded plastic parts can be realized, there are still some problems in daily use. Manual unloading is not only labor-intensive and time-consuming, but also affects the overall production efficiency. On the other hand, although the degree of automation of negative pressure adsorption has been improved, it is difficult for its fixed suction cup to adjust adaptively when facing molded parts of various shapes, especially when the heights are different, resulting in a discount in the adsorption efficiency and effect, limiting the wide application. In addition, when switching to produce products of different sizes, the existing unloading device lacks a quick adjustment and positioning mechanism, which is not convenient for quick repositioning, thereby hindering the continuous and efficient unloading operation of blister forming machines. Utility Model Content

[0004] In view of this, the utility model provides a feeding device for a blister forming machine, which can realize adaptive floating of the suction cup through the feeding mechanism, ensuring that each suction cup can effectively contact the molded plastic part, meeting the feeding operation needs when the height of the same molded plastic part is different, greatly improving the application scope of the feeding device for the blister forming machine, realizing rapid repositioning of the suction cup array, adapting to diversified production needs, meeting the feeding needs of molded plastic parts of different specifications and sizes, and realizing continuous and efficient material feeding operations of the blister forming machine.

[0005] In order to solve the above technical problems, the utility model provides a feeding device for a vacuum forming machine, comprising a mounting frame and a feeding mechanism arranged in the mounting frame, the feeding mechanism comprising a dovetail slide groove 1 which is laterally symmetrically arranged on the left and right walls of the mounting frame, a sliding plate is slidably connected between the two dovetail slide grooves 1, sliding rods are slidably connected in sliding holes which are laterally symmetrically arranged at the left and right ends of the sliding plate, a rectangular frame is arranged at the front end between the two sliding rods, dovetail slide grooves 2 which are laterally symmetrically distributed are arranged at the left and right ends of the rectangular frame, a guide rail which is uniformly distributed longitudinally is slidably connected between the two dovetail slide grooves 2, sliders which are uniformly distributed laterally are slidably connected in the guide rails, a connecting tube is arranged in the middle part of the lower surface of the slider, the lower end of the connecting tube is slidably connected to the sliding tube, a suction cup is arranged at the lower end opening of the sliding tube, and a buffer assembly is arranged between the connecting tube and the sliding tube.

[0006] The buffer assembly includes an annular plate 1 respectively arranged on the upper end of the outer arc surface of the sliding tube, an annular plate 2 is provided on the upper end of the outer arc surface of the connecting tube, a spring is provided between the annular plate 1 and the vertically adjacent annular plate 2, and the springs are movably sleeved on the outside of the connecting tube and the sliding tube which are vertically adjacent to each other as a group.

[0007] The threaded holes arranged in the middle of the upper end surface of the slider are all threadedly connected with locking bolts, and the locking bolts respectively interfere with the upper surfaces of the vertically adjacent guide rails; the threaded holes arranged laterally symmetrically on the left and right surfaces of the guide rails are all threadedly connected with limiting bolts, and the left and right surfaces of the rectangular frame are respectively coordinated with the limiting bolts adjacent to the same side.

[0008] An electric push rod is provided in the mounting opening arranged in the middle of the sliding plate, the front end of the telescopic end of the electric push rod is fixedly connected to the rear surface of the rectangular frame, and the electric push rod is electrically connected to an external single-chip computer; an electric telescopic rod is provided in the assembly opening arranged in the middle of the lower end of the mounting frame, the upper end of the telescopic end of the electric telescopic rod is fixedly connected to the lower surface of the sliding plate, and the electric telescopic rod is electrically connected to the external single-chip computer.

[0009] The four corners of the lower surface of the mounting frame are provided with symmetrically distributed fixing holes.

[0010] The beneficial effects of the above technical solution of the utility model are as follows:

[0011] First, the staff pre-connects the connecting pipe with the diversion system of the external vacuum compressor to ensure that the air path is unobstructed. Once the blister molding machine issues a material unloading instruction, the external single-chip computer performs the material unloading process according to the set programming. The external single-chip computer controls the operation of the electric push rod and the electric telescopic rod. The telescopic end of the electric telescopic rod extends to drive the sliding plate and its ancillary mechanisms to move upward synchronously. After the suction cup moves to the set height, the external single-chip computer controls the electric telescopic rod to stop operating, and at the same time controls the operation of the electric push rod. The movement of the telescopic end of the electric push rod drives the rectangular frame and its annular mechanisms to move along the sliding hole to the processing site of the blister molding machine.

The telescopic end of the electric telescopic rod moves downward, driving the sliding plate and its annular mechanisms to move downward synchronously. The suction cup will contact the molded plastic part during the downward movement. When the molded plastic parts are of different heights, the corresponding suction cup, sliding tube and annular plate will overcome the spring together. The elastic force of the spring is less than the negative pressure suction generated by the external vacuum compressor. Then the external single-chip computer controls the electric push rod to operate in the reverse direction, and the telescopic end of the electric push rod retracts, thereby driving the rectangular frame and its affiliated mechanisms to move outward along the sliding hole. Finally, the external single-chip computer controls the external vacuum compressor to release the pressure. At this time, the molded plastic parts fall off naturally under the action of gravity, completing the unloading process and realizing the adaptive floating of the suction cups. It ensures that each suction cup can effectively contact the molded plastic parts, meeting the unloading operation requirements of the same molded plastic parts with different heights, and greatly improving the application range of the unloading device for the blister molding machine. When encountering molded plastic parts of different specifications, you only need to loosen the locking bolts and limit bolts in turn, and then slide the relative positions of the guide rails and the sliders to achieve rapid repositioning of the suction cup array, adapt to diverse production needs, meet the needs of unloading molded plastic parts of different specifications and sizes, and achieve continuous and efficient unloading operations of the blister molding machine. The fixing holes make it convenient for relevant staff to quickly fix the mounting frame and its auxiliary mechanisms to the designated workplace of the blister molding machine.

A connecting tube 207 is provided in the middle of the lower surface of the slider 206, and a sliding tube 208 is slidably connected to the lower end of the connecting tube 207. A suction cup 209 is provided at the lower end opening of the sliding tube 208, and a buffer component is provided between the connecting tube 207 and the sliding tube 208; an electric push rod 600 is provided in the mounting opening provided in the middle of the sliding plate 201, and the front end of the telescopic end of the electric push rod 600 is fixedly connected to the rear surface of the rectangular frame 203, and the electric push rod 600 is electrically connected to an external single-chip computer; an electric telescopic rod 700 is provided in the assembly opening provided in the middle of the lower end of the mounting frame 100, and the upper end of the telescopic end of the electric telescopic rod 700 is fixedly connected to the lower surface of the sliding plate 201, and the electric telescopic rod 700 is electrically connected to an external single-chip computer.

[0020] like Figure 1-3 As shown, the buffer assembly includes an annular plate 1 300 respectively arranged on the upper end of the outer arc surface of the sliding tube 208, and an annular plate 2 301 is provided on the upper end of the outer arc surface of the connecting tube 207.

[0021] like Figure 1-4 As shown, the threaded holes arranged in the middle of the upper end surface of the slider 206 are threadedly connected with locking bolts 400, and the locking bolts 400 respectively interfere with the upper surfaces of the vertically adjacent guide rails 205; the threaded holes arranged laterally symmetrically on the left and right surfaces of the guide rails 205 are threadedly connected with limiting bolts 500, and the left and right surfaces of the rectangular frame 203 are respectively arranged to cooperate with the limiting bolts 500 adjacent to the same side.

[0022] The working principle of the unloading device for the vacuum forming machine provided by the utility model is as follows: first, the staff pre-connects the connecting pipe 207 with the diversion system of the external vacuum compressor to ensure that the gas path is unobstructed. Once the vacuum forming machine issues an unloading instruction, the external single-chip microcomputer performs the unloading process according to the set programming. The external single-chip microcomputer controls the operation of the electric push rod 600 and the electric telescopic rod 700. The telescopic end of the electric telescopic rod 700 extends to drive the sliding plate 201 and its auxiliary mechanism to move upward synchronously. After the suction cup 209 moves to the set height, the external single-chip microcomputer controls the electric telescopic rod 700 to stop operating, and at the same time controls the operation of the electric push rod 600. The telescopic end of the electric push rod 600 moves to drive the rectangular frame 203 and its subsidiary mechanisms move along the slide hole into the processing place of the vacuum forming machine. After the suction cup 209 moves to the top of the molded plastic part, the external single chip microcomputer controls the electric push rod 600 to stop operating, and at the same time controls the electric telescopic rod 700 to operate in the opposite direction through the external single chip microcomputer. The telescopic end of the electric telescopic rod 700 moves downward to drive the sliding plate 201 and its subsidiary mechanisms to move downward synchronously. During the downward movement of the suction cup 209, it will contact the molded plastic part. When the molded plastic part is of different heights, the corresponding suction cup 209, sliding tube 208 and annular plate 300 will overcome the elastic force of the spring 302 and move upward to avoid. After the suction cup 209 is in contact with the molded plastic part, the external single chip microcomputer controls the external vacuum compression The machine is operated, and the external vacuum compressor causes the suction cup 209 to generate negative pressure suction through the connecting pipe 207 and the sliding pipe 208, thereby adsorbing the molded plastic part, and then the external single-chip computer controls the telescopic end of the electric telescopic rod 700 to move upward, and the upward movement of the telescopic end of the electric telescopic rod 700 drives the sliding plate 201 and its auxiliary mechanisms to move upward synchronously, thereby taking out the molded plastic part, and the elastic force of the spring 302 is less than the negative pressure suction generated by the external vacuum compressor, and then the external single-chip computer controls the electric push rod 600 to reverse the stop operation, and the telescopic end of the electric push rod 600 retracts, thereby driving the rectangular frame 203 and its auxiliary mechanisms to move outward along the sliding hole, and finally the external single-chip computer controls the external vacuum compressor to release the pressure, and then the molded plastic part is taken out. The plastic parts fall off naturally under the action of gravity, completing the unloading process, realizing the adaptive floating of the suction cup 209, ensuring that each suction cup can effectively contact the molded plastic parts, meeting the unloading operation requirements when the heights of the same molded plastic parts are different, and greatly improving the application scope of the unloading device for the blister molding machine. When encountering molded plastic parts of different specifications, it is only necessary to loosen the locking bolt 400 and the limit bolt 500 in turn, and then slide the guide rail 205 and the slider 206 to the relative position, so as to realize the rapid repositioning of the suction cup 209 array, adapt to diversified production needs, meet the unloading needs of molded plastic parts of different specifications and sizes, and realize continuous and efficient material unloading operations of the blister molding machine.
