Description

Technical Field

[0001] This utility model belongs to the field of blister tray production technology, specifically relating to a blister tray manufacturing machine for loading and unloading molds. Background Technology

[0002] Blister trays are a common packaging material widely used in many industries such as electronics, food, and medicine. They have advantages such as being lightweight, durable, and recyclable. Blister tray manufacturing machines are the key equipment for producing blister trays. Their working principle is to heat plastic sheets and use vacuum adsorption technology to make the plastic sheets fit into the mold and form the blister trays.

[0003] Problems with existing technology:

[0004] In the traditional blister tray production process, a single mold and single material production method is usually adopted. The plastic sheet to be produced is placed on the support frame on top of the mold, and the top of the plastic sheet is heated and softened by heating tubes. However, the traditional heating equipment has a slow heating speed and uneven temperature distribution, which leads to large differences in wall thickness, strength and other aspects of the formed tray, resulting in a high defect rate. Utility Model Content

[0005] The purpose of this invention is to provide a molded blister tray manufacturing machine that can improve heating efficiency and production quality by rotating the closed box cover so that the heating tubes are located at the top and bottom ends of the plastic sheet.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A blister tray manufacturing machine for loading and unloading molds includes an operating table. A rotating rod is rotatably mounted through the top of the rear end of the operating table. A box cover is fixedly fitted on the outer surface of the rotating rod. Helical gears are fixedly fitted at both ends of the rotating rod. Rotating rods are embedded through the top of both sides of the operating table. Spur gears are fixedly fitted on the outer surfaces of the front and rear ends of the rotating rods. Helical gears are fixedly installed at the rear ends of the two rotating rods and at the bottom of the helical gears. The helical gears are meshed and connected. Support plates are slidably mounted on the top of both sides of the operating table. Teeth are equidistantly arranged at the front and rear ends of the bottom of the two support plates and at the top of the spur gears. The spur gears are meshed and connected with the corresponding teeth.

[0008] A cylinder is fixedly installed at the center of the bottom of the operating table, and a fixed platform is fixedly installed on the top of the cylinder. The fixed platform is slidably disposed inside the operating table. A sliding groove is opened through the top of the fixed platform around the center. A fixed rod is slidably disposed inside the sliding groove. A slider is sleeved on the top of each fixed rod. A sliding plate is disposed on the outside of the two sliders.

[0009] Both sides of the top of the fixed platform are integrally fixed with baffles. A pull rod is slidably installed through the center of each of the two baffles. Springs are sleeved on the outer surface of the two pull rods. The two pull rods are fixedly connected to one side of the corresponding slide plate at one end close to each other.

[0010] Heating tubes are embedded in the bottom of the box cover and the top of the support plate. The heating tubes are electromagnetic induction heating.

[0011] The technical effects achieved by this utility model are as follows:

[0012] In this invention, when manufacturing a pallet, the lid is opened, and a plastic sheet is placed on top of the workbench. After placement, the lid is rotated again to fix the plastic sheet. Simultaneously, the rotation of the lid drives a helical gear one to rotate, which in turn causes a helical gear two meshing with it to rotate, which in turn causes a spur gear to rotate. Through the teeth meshing with the spur gear, the support plate slides inward into the workbench and moves to the bottom of the plastic sheet. The plastic sheet is then rapidly heated by heating tubes at the bottom of the lid and the top of the support plate, improving production efficiency. At the same time, the electromagnetic induction heating method improves the uniformity of heating of the sheet and enhances the quality of the finished pallet.

[0013] By pulling the lever and squeezing the spring, the lever causes the slide plate to slide, which in turn causes the fixing rod to slide along the inside of the slide groove, thereby quickly opening and placing the mold. This facilitates the quick replacement of different mold models. At the same time, the spring squeezes the fixing rod to quickly fix the mold, avoiding the damage that may be caused by fixing the mold with screws, thus improving the production quality of the pallet.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-4 As shown, a molded blister tray manufacturing machine includes an operating table 1. A rotating rod 9 is rotatably mounted through the top of the rear end of the operating table 1. A box cover 2 is fixedly sleeved on the outer surface of the rotating rod 9. Helical gears 4 are fixedly sleeved at both ends of the rotating rod 9. Helical gears 5 are fixedly installed at the rear end of the two rotating rods 18 and at the bottom of the helical gears 4. The helical gears 4 and 5 are meshed and connected.

[0022] See attached document Figure 2 and Figure 4 The top of both sides of the operating table 1 is fitted with a rotating rod 18 through the top. The outer surfaces of the front and rear ends of the rotating rod 18 are fixedly fitted with spur gears 19. The top of both sides of the operating table 1 is slidably fitted with a support plate 3. The front and rear ends of the bottom of the two support plates 3 and the top of the spur gears 19 are equidistantly fitted with teeth 17. The spur gears 19 are meshed with the corresponding teeth 17. The bottom of the box cover 2 and the top of the support plate 3 are fitted with heating tubes 6. The heating tubes 6 are electromagnetic induction heating.

[0023] According to the above structure, when performing thermoforming on a tray, the plastic sheet to be processed is placed on the top of the workbench 1, and the lid 2 is rotated to fix the plastic sheet from the top. When the lid 2 rotates, the rotating rod 19 drives the helical gear 4 to rotate, which in turn causes the helical gear 2 5 meshing with the helical gear 4 to rotate. The rotation of the helical gear 2 5 drives the two spur gears 19 to rotate through the rotating rod 2 18, which in turn causes the support plate 3 meshing with the spur gear 19 to reciprocate, thereby causing the two support plates 3 to slide to the bottom of the plastic sheet. The heating tubes 6, which are equidistantly arranged at the bottom of the lid 2 and the top of the support plate 3, heat and soften both the top and bottom surfaces of the plastic sheet, improving the efficiency of heating and softening the plastic sheet. At the same time, the heating method of the heating tubes 6 is electromagnetic induction heating, which improves the thermal efficiency and increases the uniformity of heating compared to traditional resistance heating.

[0024] See attached document Figure 1 and Figure 3 A cylinder 8 is fixedly installed at the center of the bottom of the operating table 1. A fixed platform 7 is fixedly installed on the top of the cylinder 8. The fixed platform 7 is slidably disposed inside the operating table 1. A sliding groove 11 is opened through the top of the fixed platform 7 around the center. A fixed rod 13 is slidably disposed inside the sliding groove 11. A slider 14 is sleeved on the top of each fixed rod 13. A sliding plate 12 is disposed on the outside of the two sliders 14. A baffle 10 is integrally fixed on both sides of the top of the fixed platform 7. A pull rod 16 is slidably disposed through the center of each baffle 10. A spring 15 is sleeved on the outer surface of each pull rod 16. The two pull rods 16 are fixedly connected to one side of the corresponding sliding plate 12 at one end close to each other.

[0025] According to the above structure, when it is necessary to change the mold, by pulling the pull rods 16 on both sides of the top of the fixed platform 7, the pull rods 16 drive the slide plate 12 to slide and squeeze the spring 15. At the same time, the slide plate 12 drives the fixed rod 13 to slide along the slide groove 11, so that the fixed rod 13 moves away from the center of the fixed platform 7, thereby quickly changing the mold of the required model. The spring 15 rebounds and drives the fixed rod 13 to quickly return to its original position, clamping the mold and improving the efficiency of mold changing. At the same time, the traditional fixing method is mostly bolt connection, which can easily cause damage to the mold or equipment during disassembly and installation. By applying force to the fixed rod 13 by the spring 15, mold damage can be reduced and production quality can be improved.

[0026] The working principle of this utility model is as follows: When performing thermoforming on a tray, the plastic sheet to be processed is placed on the top of the operating table 1, and the lid 2 is rotated to fix the plastic sheet from the top. When the lid 2 rotates, the rotating rod 19 drives the helical gear 4 to rotate, which in turn causes the helical gear 2 5 meshing with the helical gear 4 to rotate. The rotation of the helical gear 2 5 drives the two spur gears 19 to rotate through the rotating rod 2 18, which in turn causes the support plate 3 meshing with the spur gear 19 to reciprocate, thereby causing the two support plates 3 to slide to the bottom of the plastic sheet. The heating tubes 6, which are equidistantly arranged at the bottom of the lid 2 and the top of the support plate 3, heat and soften both the top and bottom surfaces of the plastic sheet, improving the efficiency of heating and softening the plastic sheet. At the same time, the heating method of the heating tubes 6... Electromagnetic induction heating improves thermal efficiency and, compared to traditional resistance heating, increases heating uniformity. When mold replacement is required, pulling the pull rods 16 on both sides of the top of the fixed platform 7 causes the slide plate 12 to slide and compress the spring 15. Simultaneously, the slide plate 12 causes the fixed rod 13 to slide along the slide groove 11, moving the fixed rod 13 away from the center of the fixed platform 7, thus quickly replacing the required mold model. The spring 15 then rebounds, causing the fixed rod 13 to quickly return to its original position and clamp the mold, improving mold replacement efficiency. In addition, traditional fixing methods often use bolt connections, which can easily damage the mold or equipment during disassembly and installation. Applying force to the fixed rod 13 by the spring 15 reduces mold damage and improves production quality.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
