Description

Technical Field

[0001] This utility model relates to the technical field of aluminum-plastic blister packaging machines, specifically a forming device for an anti-jamming aluminum-plastic blister packaging machine. Background Technology

[0002] Aluminum-plastic blister packaging machines are automated packaging equipment used for products such as pharmaceuticals, food, and electronic components. They seal the product between plastic blister packs and aluminum foil, forming independent, moisture-proof, and oxidation-proof packaging units. This packaging method is widely used in the pharmaceutical industry for products such as tablets, capsules, and suppositories.

[0003] When using an aluminum-plastic blister packaging machine, aluminum foil and plastic layers are mechanically deformed into blister shapes under the action of a powerful stamping die (punch + die). However, this cold-pressing process still has the problem of material jamming. That is, the material may stop or break during the conveying and stamping process due to uneven deformation, uncontrolled tension or poor die matching, which seriously affects production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a forming device for an anti-jamming aluminum-plastic blister packaging machine, so as to solve the problem mentioned in the background art. When using the aluminum-plastic blister packaging machine, the aluminum foil and plastic layer are mechanically deformed into a blister shape under the action of a strong stamping die (punch + die). However, this cold pressing forming process still has the problem of material jamming. That is, the material stops or breaks during the conveying and stamping process due to uneven deformation, uncontrolled tension or poor die matching, which seriously affects the production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forming device for an anti-jamming aluminum-plastic blister packaging machine, comprising a base and a pressing part:

The bottom of the lifting frame plate is provided with a pressing protrusion. An extrusion concave block is vertically slidably installed inside the sliding groove. A spring b is provided at the bottom of the extrusion concave block. The lifting frame plate descends and the pressing protrusion cooperates with the sliding groove and the extrusion concave block inside the sliding groove to complete the cold pressing operation.

[0007] By adopting the above technical solution, the lowering protrusion can be pressed down by the lifting frame plate, so that the extrusion concave block slides in the chute and compresses the spring b to complete the cold pressing molding. The spring b provides the reset force, so that the extrusion concave block returns to its original position automatically, avoiding the material from getting stuck in the chute.

[0008] Preferably, the pressing part also has a pop-out bracket disposed at the bottom of the lifting frame plate, the bottom of the lifting frame plate has a groove, the pop-out bracket is embedded in the groove and slidably connected to the lifting frame plate.

[0012] Preferably, the pressing part also has round holes on both sides of the ejector frame, and the base is provided with limit rods on both sides, which pass vertically through the round holes and slide vertically with the ejector frame.

[0014] Preferably, the pressing part also has a spring a nested outside the limiting rod, the spring a being located between the base and the ejector.

[0015] By adopting the above technical solution, spring a can provide buffering force to reduce the impact when the ejector frame descends, and after cold pressing is completed, spring a assists the ejector frame to quickly reset, thereby improving production efficiency.

[0016] Preferably, the pressing protrusion is located directly above the slide groove, and a cylinder is provided on the top of the support frame, the output end of which is connected to the top of the lifting frame plate.

[0017] By adopting the above technical solution, the lifting frame can be raised and lowered by a cylinder to achieve automated cold pressing operation, and the pressing protrusion can be precisely aligned with the slide groove to ensure molding quality.

[0028] 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.

[0029] Example 1

[0030] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a forming device for an anti-jamming aluminum-plastic blister packaging machine, comprising a base 1 and a pressing part 2.

[0031] A support frame 101 is provided on the top of the base 1. A slide groove 102 is provided on the top of the base 1. The pressing part 2 is located on the top of the base 1. The pressing part 2 has a lifting frame plate 201 that is vertically slidably disposed in the support frame 101. A pressing protrusion 202 is provided at the bottom of the lifting frame plate 201. An extrusion concave block 208 is vertically slidably disposed inside the slide groove 102. A spring b209 is provided at the bottom of the extrusion concave block 208. The lifting frame plate 201 descends and the pressing protrusion 202 cooperates with the slide groove 102 and the extrusion concave block 208 in the slide groove 102 to complete the cold pressing operation. The pressing protrusion 202 can be pressed down by the lifting frame plate 201, so that the extrusion concave block 208 slides in the slide groove 102 and compresses the spring b209 to complete the cold pressing molding. The spring b209 provides a reset force, so that the extrusion concave block 208 automatically returns to its position to prevent the material from getting stuck in the slide groove 102.

[0032] Example 2

[0033] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a forming device for an anti-jamming aluminum-plastic blister packaging machine, comprising a pressing part 2, an ejector frame 204, and an extrusion recess 208.

[0034] A pop-out frame 204 is provided at the bottom of the lifting frame plate 201. A groove 203 is provided at the bottom of the lifting frame plate 201. The pop-out frame 204 is embedded in the groove 203 and slidably connected to the lifting frame plate 201. The pop-out frame 204 can slide in the groove 203 to assist the lifting frame plate 201 in stable lifting and lowering. After cold pressing, the pop-out frame 204 can help eject the formed blister pack to prevent sticking.

[0035] Limiting grooves 103 are provided on both sides of the base 1, and limiting blocks 205 are provided at the bottom of the ejector frame 204. The limiting blocks 205 are embedded in the limiting grooves 103 and are vertically slidably connected to the base 1. The limiting blocks 205 can cooperate with the limiting grooves 103 to ensure that the ejector frame 204 moves only in the vertical direction, avoids deviation, improves the stability of the ejector frame 204, and prevents it from shaking during movement.

[0036] The ejector frame 204 has round holes 206 on both sides, and the base 1 has limit rods 104 on both sides. The limit rods 104 pass vertically through the round holes 206 and slide vertically with the ejector frame 204. The movement trajectory of the ejector frame 204 can be further restricted by the limit rods 104 passing through the round holes 206, ensuring its precise lifting and lowering, and preventing the ejector frame 204 from tilting due to uneven force, thereby improving the molding accuracy.

[0037] A spring a207 is nested on the outside of the limit rod 104. The spring a207 is located between the base 1 and the ejector 204. The spring a207 can provide a buffering force to reduce the impact when the ejector 204 descends. After the cold pressing is completed, the spring a207 assists the ejector 204 to quickly reset, thereby improving production efficiency.

[0038] The pressing protrusion 202 is located directly above the slide groove 102. A cylinder 210 is installed on the top of the support frame 101. The output end of the cylinder 210 is connected to the top of the lifting frame plate 201. The cylinder 210 is a device that converts the energy of compressed air into mechanical energy. The working principle of the cylinder 210 is based on the mechanical movement achieved by the push of compressed air. The above is the prior art and will not be elaborated further below. When selecting the model, its power should be selected to match the needs of the device to ensure that the object to be driven is driven. The lifting frame plate 201 can be driven to rise and fall by the cylinder 210 to realize automated cold pressing operation and make the pressing protrusion 202 and the slide groove 102 accurately aligned to ensure molding quality.

[0039] The bottom surface of the pressing protrusion 202 is provided with an outwardly convex arc surface, and the top surface of the extrusion concave block 208 is provided with an inwardly concave arc surface. The arc surface of the bottom surface of the pressing protrusion 202 and the top surface of the extrusion concave block 208 fit together. The arc surface matching design makes the contact between the pressing protrusion 202 and the extrusion concave block 208 more uniform and reduces stress concentration.

[0040] Working principle: First, the aluminum-plastic sheet is conveyed to the slide 102 above the base 1 via an external conveying device. The cylinder 210 is activated, driving the lifting frame 201 to move the pressing protrusion 202 downward. When the pressing protrusion 202 contacts the aluminum-plastic sheet, its outer convex arc surface fits tightly with the inner concave arc surface of the extrusion concave block 208, so that the sheet is evenly stressed and cold-pressed. At the same time, the lifting frame 201 drives the ejector frame 204 to descend, the limiting block 205 slides along the limiting groove 103, and the spring a207 is compressed to provide buffering force. After forming, the cylinder 210 retracts, the lifting frame 201 rises, and the spring a207 pushes the ejector frame 204 to reset, assisting in ejecting the formed blister and preventing adhesion. The extrusion concave block 208 automatically returns to its position under the elastic force of the spring b209, avoiding material jamming in the slide 102 and ensuring continuous production stability.
