Description

Technical Field

[0001] This utility model relates to the field of packaging box production technology, and in particular to a forming device for producing packaging boxes. Background Technology

[0002] Packaging boxes are containers designed to protect, display, and transport products. They are widely used in various industries such as food, pharmaceuticals, cosmetics, and electronics. Their core functions include protecting the safety of goods, enhancing product added value, and conveying brand information.

[0003] In the packaging box production process, the forming stage is crucial, directly affecting the quality and production efficiency of the packaging boxes. Currently, packaging box forming devices on the market have some shortcomings. On the one hand, the demolding method of some devices is not efficient enough, and the friction and adhesion between the packaging box and the mold are large, resulting in difficulty in demolding, which can easily damage the packaging boxes and affect the yield. On the other hand, the cooling stage is inefficient, and the cooling speed of the formed packaging boxes is slow, which prolongs the production cycle, reduces the overall production efficiency, and is not practical enough. Therefore, it is necessary to redesign a forming device for producing packaging boxes to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a molding device for producing packaging boxes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A forming apparatus for producing packaging boxes includes a processing table. A prismatic rod is fixedly mounted on the upper surface of the processing table via a connecting frame. A slider is slidably mounted on the outer wall of the prismatic rod. The outer wall of the slider is connected to the inner wall of the connecting frame via a reset mechanism. A lower mold is fixedly mounted on the upper surface of the slider via a mounting plate. An extrusion frame is fixedly mounted on the bottom wall of the mounting plate. A first motor is fixedly mounted on the upper surface of the processing table via a support mechanism. A cam is fixedly mounted on the outer wall of the output shaft of the first motor. A bidirectional screw is rotatably mounted on the bottom wall of the processing table via a moving frame. A second motor connected to the bidirectional screw is fixedly mounted on the outer wall of the moving frame. Two moving blocks are threadedly mounted on the outer wall of the bidirectional screw via a limiting mechanism.

[0007] Preferably, the reset mechanism includes a reset spring mounted on the outer wall of the prism rod, and the two ends of the reset spring are elastically connected to the inner wall of the connecting frame and the outer wall of the slider, respectively.

[0008] Preferably, the support mechanism includes a support plate fixedly installed on the upper surface of the processing table, and the first motor is fixedly installed on the bottom wall of the support plate.

[0009] Preferably, the limiting mechanism includes a limiting rod fixedly installed inside the movable frame, the limiting rod sliding through the two movable blocks.

[0010] Preferably, a connecting rod is fixedly installed on the upper surface of each of the two movable blocks, and a movable opening is provided on the upper surface of the processing table to cooperate with the two connecting rods.

[0011] Preferably, a cooler is fixedly installed at the end of each of the two connecting rods, and a blower pipe is fixedly installed on the outer wall of each of the two cooler outlet pipes, and a blower port communicating with the interior is opened on the outer wall of each of the two blower pipes.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as cam, extrusion frame, slider, and return spring, the first motor drives the cam to rotate at high speed during demolding, which applies force to the extrusion frame to make the slider vibrate at high frequency on the prism rod, causing the lower mold to vibrate, breaking the adsorption and friction between the packaging box and the mold. The return spring enhances the vibration effect, achieving easy demolding and improving the yield and efficiency.

[0014] 2. By setting up components such as connecting rods, air coolers, and air ducts, the second motor drives the bidirectional screw to rotate, causing the moving block to move the air cooler and air duct closer to the lower mold via the connecting rods. When the air cooler is activated, cold air is blown out evenly from the air outlet of the air duct, which can quickly and comprehensively cool the initially formed packaging box, accelerate the solidification and shaping of the packaging box, effectively shorten the molding cycle, and thus improve the efficiency of the entire packaging box production.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A forming device for producing packaging boxes includes a processing table 1. A prismatic rod 3 is fixedly installed on the upper surface of the processing table 1 through a connecting frame 2. A slider 4 is slidably installed on the outer wall of the prismatic rod 3. The outer wall of the slider 4 is connected to the inner wall of the connecting frame 2 through a reset mechanism. The reset mechanism includes a reset spring 5 installed on the outer wall of the prismatic rod 3. The two ends of the reset spring 5 are elastically connected to the inner wall of the connecting frame 2 and the outer wall of the slider 4, respectively.

[0023] A lower mold 6 is fixedly mounted on the upper end face of the slider 4 via a mounting plate. An extrusion frame 7 is fixedly mounted on the bottom wall of the mounting plate. A first motor 9 is fixedly mounted on the upper end face of the processing table 1 via a support mechanism. The support mechanism includes a support plate 8 fixedly mounted on the upper end face of the processing table 1. The first motor 9 is fixedly mounted on the bottom wall of the support plate 8. A cam 10 is fixedly mounted on the outer wall of the output shaft of the first motor 9. A bidirectional screw 12 is rotatably mounted on the bottom wall of the processing table 1 via a moving frame 11. A second motor 13 connected to the bidirectional screw 12 is fixedly mounted on the outer wall of the moving frame 11.

[0024] Two moving blocks 15 are threadedly installed on the outer wall of the bidirectional screw 12 through a limiting mechanism. The limiting mechanism includes a limiting rod 14 fixedly installed inside the moving frame 11. The limiting rod 14 slides through the two moving blocks 15 and can limit the two moving blocks 15 so that the two moving blocks 15 can only move axially along the outer wall of the bidirectional screw 12. A connecting rod 16 is fixedly installed on the upper end face of each of the two moving blocks 15. The upper end face of the processing table 1 is provided with a moving opening that cooperates with the two connecting rods 16. A cooler 17 is fixedly installed at the end of each of the two connecting rods 16. A blower pipe 18 is fixedly installed on the outer wall of the outlet pipe of each of the two coolers 17. A blower port communicating with the interior is provided on the outer wall of each of the two blower pipes 18.

[0025] When this utility model is used, the material to be incorporated can be injected into the lower mold 6. Then, the upper mold of the injection molding device can be used to extrude the molten material inside the lower mold 6. During the extrusion process, the material fills the mold cavity under the pressure of the upper and lower molds, forming the initial shape of the packaging box. At this time, the second motor 13 can drive the bidirectional screw 12 to rotate. Under the restriction of the limiting rod 14, the two moving blocks 15 move towards or away from each other along the bidirectional screw 12. The connecting rod 16 drives the air cooler 17 and the air pipe 18 to move and approach the lower mold 6. After the air cooler 17 is started, the cold air is blown out evenly from the air outlet of the air pipe 18 to quickly cool the initially formed packaging box. Under the action of the cold air, the packaging box quickly solidifies and shapes, shortening the molding cycle.

[0026] After the packaging box has cooled down, the second motor 13 can drive the bidirectional screw 12 to rotate in the opposite direction. Under the restriction of the limit rod 14, the two moving blocks 15 move in the opposite direction along the bidirectional screw 12. At this time, the connecting rod 16 drives the air cooler 17 and the air blower 18 to move away from the lower mold 6. When demolding, the first motor 9 starts, and its output shaft drives the cam 10 to rotate at high speed. Since the profile of the cam 10 is not a regular circle, it will continuously apply a force with periodic changes in magnitude and direction to the extrusion frame 7 during its high-speed rotation. This force is transmitted through the extrusion frame 7 to the mounting plate connected to the slider 4, which in turn causes the slider 4 to generate high-frequency and small-amplitude left and right vibrations on the prism rod 3. The vibration of the slider 4 directly drives the lower mold 6 to vibrate synchronously.

[0027] During the shaking process, the friction and adsorption forces between the packaging box, which was originally tightly fitted in the mold cavity, and the lower mold 6 are continuously broken and weakened. At the same time, this high-frequency shaking causes the packaging box to be subjected to micro-vibrations evenly in all parts, avoiding damage to the packaging box caused by local stress concentration. In order to enhance the shaking effect, the return spring 5 also continuously extends, retracts and rebounds when the slider 4 shakes, further amplifying the amplitude and frequency of the shaking. In addition, the special shape design of the prism rod 3 ensures that the slider 4 can only shake stably along the direction of the rod without deviation or wobbling. As the shaking continues, the packaging box gradually separates from the lower mold 6, thus facilitating demolding.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
