Abstract
Description
Technical Field
[0001] This utility model relates to the field of blister box production technology, and in particular to a blister box forming device. Background Technology
[0002] In a broad sense, blister packs refer to all blister packs; in a narrow sense, they refer to a specific type: blister packs formed from sheet material using vacuum forming, with the lid attached to the container. They are often made of PS (polystyrene), but some have separate lids and bottoms, and different materials can be used. For example, Japanese fast food boxes often have black PS bottoms and transparent PET lids. Vacuum forming is a plastic processing technique; its main principle is to heat a flat, rigid plastic sheet until it softens, then vacuum-form it onto a mold surface, where it cools and solidifies.
[0003] When processing and shaping the adsorption box, vacuum adsorption forming equipment is usually used. The vacuum adsorption forming equipment consists of an unwinding mechanism, a limiting and guiding structure, and a vacuum adsorption mechanism. The unwinding mechanism unwinds the material, the limiting and guiding mechanism limits and guides the material, and the vacuum adsorption mechanism adsorbs and shapes the material.
[0004] During the use of vacuum adsorption forming equipment, the metal rollers in the limiting guide mechanism contact the top and bottom of the material. When the roller pressure is applied to the sheet, the microscopic protrusions on the metal surface will cut into the sheet surface, forming scratches. Also, due to the difference in hardness, visible furrow-like scratches will appear on the sheet surface. Based on the above problems, this application proposes a blister box forming device to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a blister box forming device to solve the aforementioned problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

An unwinding assembly is provided on the surface of the mounting vertical plate. A front-to-back moving assembly is provided on the top of the mounting base. A connecting frame is provided on the top of the mounting base via the front-to-back moving assembly. A side roller is rotatably mounted inside the connecting frame. An electric push rod is fixedly mounted on the top of the connecting frame. A mounting plate is fixedly mounted on the output end of the electric push rod. A guide rod is fixedly mounted on the top of the mounting plate. An elastic limiting assembly is provided inside the mounting plate.
[0008] Preferably, the unwinding assembly includes a geared motor fixedly installed on the rear side of the mounting vertical plate, an unwinding shaft fixedly provided at the output end of the geared motor, a blister pack material roll overlapping the surface of the unwinding shaft, a fixing plate overlapping the front side of the blister pack material roll, the fixing plate being slidably connected to the unwinding shaft, a fixing sleeve being threaded on the surface of the unwinding shaft, and the fixing sleeve contacting the fixing plate.
[0009] Preferably, the forward and backward moving assembly includes a rectangular plate fixedly mounted on the top of the mounting base. A servo motor is fixedly mounted on the front side of the rectangular plate, a lead screw is fixedly mounted on the output end of the servo motor, a threaded sleeve is threaded on the surface of the lead screw, a mounting bracket is fixedly mounted on the top of the threaded sleeve, a connecting plate is fixedly mounted on the bottom of the mounting bracket, a mounting shaft is fixedly mounted inside the connecting plate, and a support roller is rotatably mounted on the end of the mounting shaft.
[0010] Preferably, the elastic limiting component includes a connecting groove formed on the surface of the mounting plate, a sliding plate slidably disposed inside the connecting groove, a spring connected to the sliding plate facing the spring, a moving rod fixedly disposed on the side of the sliding plate away from the spring, a limiting ring slidably disposed on the surface of the moving rod, the limiting ring being fixedly installed inside the connecting groove, a ball being rotatably disposed inside the moving rod, a limiting plate being rotatably disposed on the surface of the ball, and the limiting plate being fixedly connected to the moving rod.
[0011] Preferably, the end of the moving rod away from the sliding plate is provided with an installation groove, and the surface of the limiting plate is provided with a limiting groove.
[0012] Preferably, the mounting bracket has a U-shaped structure, is made of metal, and has four supporting rollers that are symmetrically distributed.
[0013] Preferably, the number of the balls is several, and the balls are symmetrically distributed, and the balls are made of ceramic material.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This blister box forming device moves the mounting frame by moving the front and rear moving components, which in turn moves the side rollers and electric push rods, causing the mounting plate to bring the elastic limiting component into contact with the material. Through the elastic action of the elastic limiting component itself, the material is elastically limited, avoiding the situation where the microscopic protrusions on the surface of the metal rollers cut into the surface of the sheet and form scratches when the pressure of the rigidly installed rollers is applied to the sheet. This avoids the situation where the rigidly connected metal rollers cause visible plow-groove scratches on the surface of the sheet due to the difference in hardness, thus avoiding scratches on the surface of the formed blister box.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example: Refer to Figure 1-6A blister box forming device includes a mounting base 1, a vacuum adsorption forming machine body 2 and a mounting vertical plate 3 fixedly mounted on the top of the mounting base 1, an unwinding assembly on the surface of the mounting vertical plate 3, and a front-back moving assembly on the top of the mounting base 1. The front-back moving assembly includes a rectangular plate 9 fixedly mounted on the top of the mounting base 1, a servo motor 10 fixedly mounted on the front side of the rectangular plate 9, a lead screw 28 fixedly mounted on the output end of the servo motor 10, a threaded sleeve 11 on the surface of the lead screw 28, a mounting frame 12 fixedly mounted on the top of the threaded sleeve 11, a connecting plate 13 fixedly mounted on the bottom of the mounting frame 12, a mounting shaft 14 fixedly mounted inside the connecting plate 13, and a support roller 15 rotatably mounted at the end of the mounting shaft 14. The mounting frame 12 has a U-shaped structure and is made of metal. It has four symmetrically arranged support rollers 15. A servo motor 10 drives a lead screw 28 to move the lead sleeve 11, causing the connecting plate 13 to rotate within the mounting base 1 via the mounting shaft 14, allowing the supporting rollers 15 to roll. This causes the connecting frame 16 to bring the side rollers 17 into contact with the material. Simultaneously, an electric push rod 18 moves the mounting plate 19, which in turn moves the ball bearings 26 via a moving rod 24, bringing the lower ball bearings 26 into contact with the bottom of the material. This facilitates the limiting and guiding of materials of different widths and thicknesses. The connecting frame 16 is mounted on the top of the mounting base 1 via a front-to-back moving assembly. The connecting frame 16 has an internal rotating mechanism. A side roller 17 is provided. An electric push rod 18 is fixedly installed on the top of the connecting frame 16. A mounting plate 19 is fixedly installed at the output end of the electric push rod 18. A guide rod 20 is fixedly installed on the top of the mounting plate 19. An elastic limiting component is provided inside the mounting plate 19. The elastic limiting component includes a connecting groove 21 formed on the surface of the mounting plate 19. A sliding plate 22 is slidably arranged inside the connecting groove 21. The sliding plate 22 is connected to the spring 23 facing each other. A moving rod 24 is fixedly installed on the side of the sliding plate 22 away from the spring 23. A limiting ring 25 is slidably arranged on the surface of the moving rod 24. The limiting ring 25 is fixedly installed inside the connecting groove 21. A number of balls 26 are rotatably arranged inside the moving rod 24, and the balls 26 are arranged symmetrically. The ball bearings 26 are made of ceramic material. A limiting plate 27 is rotatably mounted on the surface of the ball bearings 26. An installation groove is provided at the end of the moving rod 24 away from the sliding plate 22. A limiting groove is rolled out on the surface of the limiting plate 27. The limiting plate 27 is fixedly connected to the moving rod 24. An electric push rod 18 drives the upper mounting plate 19 to move the spring 23 and the limiting ring 25 downwards, causing the sliding plate 22 to contact the top of the material via the moving rod 24 and the ball bearings 26. This limits the material movement. When the material vibrates, the ball bearings 26 push the sliding plate 22 via the moving rod 24, compressing the spring 23. The spring 23 then pushes the sliding plate 22 back to its original position, causing the moving rod 24 to push the material back to its original position via the ball bearings 26, thus achieving elastic limiting.This avoids contact between the rigidly connected rollers and the material, preventing scratches on the material surface and thus avoiding blemishes on the molded blister pack surface caused by such scratches.
[0024] Specifically, the unwinding assembly includes a geared motor 4 fixedly installed on the rear side of the mounting vertical plate 3. An unwinding shaft 5 is fixedly installed at the output end of the geared motor 4. A blister pack material roll 6 overlaps with the surface of the unwinding shaft 5. A fixing plate 7 overlaps with the front side of the blister pack material roll 6. The fixing plate 7 is slidably connected to the unwinding shaft 5. A fixing sleeve 8 is threaded onto the surface of the unwinding shaft 5, and the fixing sleeve 8 contacts the fixing plate 7. The blister pack material roll 6 is placed on the unwinding shaft 5, so that the blister pack material roll 6 is in contact with the unwinding shaft 5. The limiting circular plate on the surface of shaft 5 contacts the fixing plate 7 and inserts it into the surface of unwinding shaft 5, so that fixing plate 7 contacts blister box material roll 6. The fixing sleeve 8 is tightened on the surface of unwinding shaft 5, so that fixing plate 7 and limiting circular plate on the surface of unwinding shaft 5 fix blister box material roll 6. The output end of the geared motor 4 drives the unwinding shaft 5 to rotate, so that unwinding shaft 5 drives blister box material roll 6 to rotate through fixing plate 7 and fixing sleeve 8, so that the material on blister box material roll 6 is unwound.
[0025] In use: The servo motor 10 drives the output end to rotate the lead screw 28, which in turn drives the lead sleeve 11 to move the mounting frame 12. The mounting frame 12 then moves the connecting plate 13, causing the connecting plate 13 to rotate inside the mounting base 1 via the mounting shaft 14 and the support roller 15. The mounting frame 12 also moves the connecting frame 16, causing the side roller 17 to contact the material. The electric push rod 18 moves the mounting plate 19, which in turn moves the ball bearings 26 via the moving rod 24, causing the lower ball bearings 26 to contact the bottom of the material. Finally, the electric push rod 18 drives the output end to move the upper mounting plate 19 downwards. The movement causes the upper mounting plate 19 to move the spring 23 and the limiting ring 25 downwards, which in turn causes the spring 23 to move the sliding plate 22 downwards, which in turn causes the sliding plate 22 to move the moving rod 24 and the limiting ring 25 downwards, so that the upper ball 26 contacts the top of the material, thus limiting the material. When the material vibrates, it pushes the ball 26 to move, which in turn pushes the sliding plate 22 through the moving rod 24 to compress the spring 23. The spring 23 then pushes the sliding plate 22 to reset, which in turn pushes the material back to its original position through the ball 26. Subsequently, the material enters the vacuum adsorption molding machine body 2, where it is processed and shaped by the vacuum adsorption molding machine body 2.
