Description

Technical Field

[0001] This utility model relates to the field of vacuum forming machine technology, specifically to a vacuum forming machine limit and continuous feeding device. Background Technology

[0002] A vacuum forming machine is a machine that uses the vacuum suction generated by a vacuum pump to mold heated and softened thermoplastic sheets into products of various shapes. During the production and processing of vacuum forming machines, a continuous feeding device is usually used to guide the material to the feed port of the vacuum forming machine.

[0003] Traditional continuous feeding devices for vacuum forming machines have a simple structure, mainly consisting of a frame with a detachable rotating shaft on the frame. A guide roller is positioned in front of the rotating shaft. During feeding, the rotating shaft is passed through the middle of the roll containing the material, then the shaft is mounted on the frame. Finally, one end of the material is passed through the guide roller and placed into the vacuum forming machine's feed inlet. However, existing continuous feeding devices typically require workers to lift the rotating shaft and roll together onto the frame. The roll containing the material is heavy, making manual handling very strenuous and increasing worker workload. Furthermore, because existing feeding devices lack limiting mechanisms for the roll, it is prone to deviation during feeding, causing the material to fail to reach the designated position accurately and affecting subsequent processing steps. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a continuous feeding device for a vacuum forming machine, thereby solving the problems mentioned in the background art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A continuous feeding device for a thermoforming machine includes a frame and a second rotating shaft. The frame is U-shaped, and two symmetrical guide blocks are installed on the top of the left and right sides of the frame. The top of the guide blocks is provided with a first positioning groove and a limiting protrusion at the front and back, respectively. Two symmetrical columns are installed on the left and right sides of the frame, and a first rotating shaft is rotatably installed between the two columns. A reduction motor for driving the first rotating shaft to rotate is installed on one of the columns. Two symmetrical reels are installed on the first rotating shaft, and steel wire ropes are wound on the reels. One end of the steel wire rope is fixed to the reel, and the other end is connected to a cylinder.

[0007] Both ends of the second rotating shaft are provided with axial limiting grooves and radial through holes. A drum and two sleeves are fitted on the second rotating shaft. The two sleeves are located at the left and right ends of the drum, respectively. The sleeves are fixed to the second rotating shaft by nut screws. A circular limiting plate is installed on the end of each sleeve near the drum.

[0008] As a preferred embodiment of the continuous feeding device for limiting the thermoforming machine, a first bracket in the shape of an inverted U is installed at the front of the top of the frame. A first guide roller is rotatably installed on the inner side of the first bracket. A second bracket in the shape of an inverted U is set on the inner side of the first bracket, located above the first guide roller. A second guide roller is rotatably installed on the inner side of the second bracket. A pair of guide rods are installed on the top of the second bracket. A guide hole is opened on the top of the first bracket for the guide rods to pass through. A push rod motor with the output rod facing downwards is installed on the top of the first bracket. The output rod of the push rod motor is fixed to the top of the second bracket. A second controller for controlling the operation of the push rod motor is installed on the outer side of the first bracket.

[0009] As a preferred embodiment of the continuous feeding device for limiting the thermoforming machine, the second rotating shaft can be horizontally mounted on the top of the frame, and the two guide blocks on the top of the frame are located in the limiting grooves at both ends of the second rotating shaft.

[0010] As a preferred embodiment of the continuous feeding device for limiting the vacuum forming machine, the steel wire rope is connected to the middle position of the side of the cylinder, and the steel wire rope and the cylinder can pass through the through hole on the second rotating shaft at the same time.

[0011] As a preferred embodiment of the continuous feeding device for limiting the thermoforming machine, the inner radius of the roller is greater than the radius of the second rotating shaft and less than the outer radius of the limiting plate.

[0012] As a preferred embodiment of the continuous feeding device for limiting the vacuum forming machine, both guide blocks are fixed to the frame by bolts, and the bottom of both guide blocks is provided with a second positioning groove. The top of the left and right sides of the frame are provided with positioning protrusions that can cooperate with the second positioning grooves.

[0013] As a preferred embodiment of the continuous feeding device for limiting the thermoforming machine, a first controller for controlling the operation of the geared motor is installed at the rear of the bottom side of the frame. The first controller is a foot pedal controller.

[0014] The beneficial effects of this utility model are:

[0015] (1) The blister machine limit continuous feeding device of this utility model connects the two ends of the second rotating shaft with a steel wire rope and drives the reel to rotate and wind up the steel wire rope by a geared motor.

[0030] Example 1:

[0031] like Figures 1 to 6As shown, this utility model provides a limiting continuous feeding device for a vacuum forming machine, mainly including a frame 1, guide blocks 2, columns 3, a first rotating shaft 4, a reel 5, a steel wire rope 6, a cylinder 7, a reduction motor 8, a second rotating shaft 9, a reel 10, a sleeve 11, a limiting plate 12, a first controller 13, a first bracket 14, a first guide roller 15, a second bracket 16, a second guide roller 17, a guide rod 18, a push rod motor 19, and a second controller 20. The frame 1 is U-shaped, and two symmetrical guide blocks 2 are fixed to the top of its left and right sides by bolts. The top of the guide blocks 2 is respectively provided with a first guide block 2. The frame 1 has a positioning groove 2-1 and a limiting protrusion 2-2. Two symmetrical columns 3 are installed on the left and right sides of the frame 1. A first rotating shaft 4 is rotatably installed between the two columns 3. A geared motor 8 is installed on one of the columns 3 to drive the first rotating shaft 4 to rotate. A first controller 13 for controlling the operation of the geared motor 8 is installed at the rear of the bottom side of the frame 1. The first controller 13 is preferably a foot pedal controller. Two symmetrical reels 5 are installed on the first rotating shaft 4. Steel wire ropes 6 are wound on the reels 5. One end of the steel wire rope 6 is fixed to the reel 5, and the other end is connected to the cylinder 7. The steel wire rope 6 is connected to the middle of the side of the cylinder 7.

[0032] The second rotating shaft 9 has axial limiting grooves 9-1 and radial through holes 9-2 at both ends, allowing it to be mounted horizontally on the top of the frame 1. Two guide blocks 2 at the top of the frame 1 are located within the limiting grooves 9-1 at both ends of the second rotating shaft 9. The limiting grooves 9-1 and guide blocks 2 cooperate to restrict the axial movement of the second rotating shaft 9 on the frame 1. A drum 10 and two sleeves 11 are fitted onto the second rotating shaft 9. The sleeves 11 are fixed to the second rotating shaft 9 by screws and are located at the left and right ends of the drum 10, respectively. The sleeves 11 are close to the drum 10... A circular limiting plate 12 is installed at the end. The inner radius of the drum 10 is larger than the radius of the second rotating shaft 9, but smaller than the outer radius of the limiting plate 12. The drum 10 is used to wind up the materials needed by the thermoforming machine. The drum 10 can rotate on the second rotating shaft 9. The distance between the two limiting plates 12 is slightly larger than the length of the drum 10. The two limiting plates 12 are used to limit the position of the drum 10 and prevent the drum 10 from shifting axially during rotation. After loosening the nut screws on the sleeve 11, the sleeve 11 can be adjusted on the second rotating shaft 9. The position can be adjusted by removing the sleeve 11 from the second rotating shaft 9, allowing workers to adjust the distance between the two limiting plates 12 according to the length of the drum 10, or to replace the drum 10 on the second rotating shaft 9. During operation, the wire rope 6 and the cylinder 7 are passed entirely through the through hole 9-2 on the second rotating shaft 9. Then, the cylinder 7 is placed horizontally. When the reduction motor 8 drives the first rotating shaft 4 to rotate, it drives the reel 5 to rotate and wind up the wire rope 6. At this time, the cylinder 7 will be stuck in the through hole 9-2 of the second rotating shaft 9, and then, under the traction of the wire rope 6, the first rotating shaft 4 will rotate. When the second rotating shaft 9 comes above the guide block 2, the first rotating shaft 4 is driven to reverse by the reduction motor 8, so that the second rotating shaft 9 is horizontally mounted between the two guide blocks 2. The wire rope 6 and the cylinder 7 are passed through the round through hole 9-2 on the second rotating shaft 9 in the opposite direction, so that the wire rope 6 and the cylinder 7 can be separated from the second rotating shaft 9. The limiting protrusion 2-2 on the guide block 2 can prevent the second rotating shaft 9 from rolling backward and falling off the frame 1. The second rotating shaft 9 is rolled forward and enters the first positioning groove 2-1 on the guide block 2, so that the feeding is completed.

[0033] The frame 1 has an inverted U-shaped first bracket 14 mounted at the front top, with a first guide roller 15 rotatably mounted inside it. An inverted U-shaped second bracket 16 is also mounted inside the first bracket 16, above the first guide roller 15. A second guide roller 17 is rotatably mounted inside the second bracket 16. A pair of guide rods 18 are mounted on the top of the second bracket 16. The top of the first bracket 14 has guide holes for the guide rods 18 to pass through. A push rod motor 19 with its output rod vertically downwards is mounted on the top of the first bracket 14, and its output rod is fixed to the top of the second bracket 16. A second controller 20 is mounted on the outside of the first bracket 14 to control the operation of the push rod motor 19. When the height of the second guide roller 17 needs to be adjusted, the push rod motor 19 is controlled by the second controller 20. The output rod of the push rod motor 19 extends and retracts, causing the second bracket 16 to move up and down along the guide rods 18, thereby adjusting the height of the second guide roller 17.

[0034] Example 2:

[0035] Based on Embodiment 1, this embodiment further optimizes the connection structure between the guide block 2 and the frame 1. The bottom of both guide blocks 2 is provided with a second positioning groove 2-3, which can cooperate with the positioning protrusions 1-1 on the top of the left and right sides of the frame 1. When the guide block 2 is connected to the frame 1, before the bolts are tightened, the guide block 2 is initially positioned by the positioning protrusions 1-1 and the second positioning grooves 2-3 to ensure that the guide block 2 is installed in an accurate position. Then the bolts are tightened to improve the installation accuracy and stability. The holes for connecting bolts on the guide block 2 are countersunk holes, and the bolts are internal hexagon screws. The head of the internal hexagon screw can be hidden by the countersunk holes to prevent the head of the bolt from affecting the rolling of the second rotating shaft 9 on the guide block 2.

[0036] Example 3:

[0037] Based on Embodiments 1 and 2, this embodiment optimizes the cooperation between the push rod motor 19 and the second guide roller 17. A displacement sensor is installed on the second bracket 16 and electrically connected to the second controller 20 to monitor the height position of the second guide roller 17 in real time. When the height of the second guide roller 17 changes, the displacement sensor transmits a signal to the second controller 20. The second controller 20 automatically controls the extension and retraction of the output rod of the push rod motor 19 according to a preset height range, so that the second guide roller 17 is always kept at a suitable height, thereby ensuring the smoothness of material conveying. In practical applications, the height of the second guide roller 17 can be flexibly adjusted by the second controller 20 according to different production needs to adapt to the conveying of materials of different thicknesses.

[0038] Working principle and usage process of this utility model:

[0039] When using this blister packaging machine's limiting continuous feeding device, firstly, the second rotating shaft 9 is passed through the middle of the drum 10 containing the material. Then, the sleeve 11 is fitted onto the second rotating shaft 9 and the machine screw is tightened. During feeding, the steel wire ropes 6 and cylinders 7 on both sides are passed through the round holes 9-2 at both ends of the second rotating shaft 9. Then, the cylinders 7 are placed horizontally so that they are locked in the round holes 9-2. Next, the reduction motor 8 is started to drive the reel 5 to rotate and wind up the steel wire rope 6, so that the second rotating shaft 9 and the drum 10 are pulled down to above the guide block 2 by the steel wire rope 6. Then, the reduction motor 8 drives the reel 5 to reverse and release the steel wire rope 6, so that the second rotating shaft 9 is horizontally mounted between the two guide blocks 2 and the guide blocks 2 are engaged with the limiting groove 9-1 on the second rotating shaft 9. Then, the steel wire ropes 6 and cylinders 7 are passed through the round holes 9-2 in the opposite direction to release the second rotating shaft 9. Finally, the second rotating shaft 9 is pushed forward into the first positioning groove 2-1 of the guide block 2, thus completing the feeding.

[0040] When the material on the roll 10 is about to run out, the new roll 10 with material can be moved to the guide block 2 according to the above operation, and the old roll 10 can be taken out for replacement, thereby realizing continuous feeding.

[0041] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
