Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically to a bending machine for producing blister film curved parts. Background Technology

[0002] In the production of curved parts made from blister film, the bending process is a crucial step. Existing bending machines for producing curved blister film parts typically employ a single-station design. During material changeovers, the bending machine is stopped and unable to perform bending operations. This results in significant time wastage during material changeovers, severely impacting production efficiency, increasing production costs, and failing to meet the demands of large-scale production. Utility Model Content

[0003] In view of the problems existing in the bending machine for producing curved parts of blister film, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a bending machine for producing curved parts of blister film, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A bending machine for producing curved parts of blister film includes a base plate and two curved blocks. The two curved blocks are symmetrically arranged on both sides of the upper surface of the base plate. A groove is formed in the middle of the upper surface of the base plate. A rotating rod is provided at both ends of the inner side of the groove. A connecting block is rotatably connected to both ends of the rotating rod. One side of the connecting block is fixedly connected to the inner wall of the groove. A first bending plate is fixedly sleeved on the rod wall of one side of the rotating rod, and a second bending plate is fixedly sleeved on the rod wall of the other side of the rotating rod. A transmission mechanism for driving the two rotating rods to rotate is provided on the front side of the base plate.

[0006] Preferably, the transmission mechanism includes gears and racks. The gears are fixedly sleeved on the front end of the rotating rod. A crossbar is provided above the two gears. The rack is fixedly mounted on the lower surface of the crossbar and located above the gears. The rack meshes with the gears. A round pin is fixedly provided on the front side of the middle end of the crossbar. A transmission rod is rotatably sleeved on the middle end of the base plate. A lever is fixedly sleeved on the front end of the transmission rod. A strip-shaped opening is provided on the rod wall of the lever. The front end of the round pin passes through the strip-shaped opening. A motor is fixedly mounted on the rear side of the base plate. The output end of the motor is fixedly connected to one end of the transmission rod.

[0007] Preferably, limit plates are provided on both sides of the arc-shaped stop, and a threaded hole is provided at one end of the limit plate. A threaded rod is threaded into the inside of the threaded hole, and one end of the threaded rod is rotatably connected to the side wall of the arc-shaped stop.

[0008] Preferably, a fixing block is fixedly provided at one end of the front side of the base plate, and a square rod is fixedly provided on the side of the fixing block near the crossbar. A square hole is opened at the end of the crossbar near the square rod, and the square rod is inserted into the square hole.

[0009] Preferably, the sidewall of the limiting plate has limiting holes on both sides of the threaded hole, and a limiting rod is slidably sleeved inside the limiting hole. One end of the limiting rod is fixedly connected to the sidewall of the arc-shaped stop.

[0010] Preferably, the end of the round pin furthest from the crossbar is fixedly fitted with an anti-detachment ring.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model involves inserting the workpiece to be bent between the arc-shaped stop and the base plate, then connecting the power supply of the motor. The motor drives the rotating rod to rotate, causing the lever to push the round pin, which in turn drives the crossbar to move. This causes the rack to drive the gear to rotate, thereby causing the first bending plate to rotate around the rotating rod to a vertical position, thus completing the automated bending operation.

[0012] 2. In this utility model, when the first bending plate rotates to a vertical position around the corresponding rotating rod as an axis, the second bending plate simultaneously rotates to a horizontal position around the corresponding rotating rod as an axis. At this time, the workpiece to be bent can be placed above the second bending plate, which can reduce the time wasted on changing materials and improve processing efficiency.

[0013] 3. In this utility model, by rotating the threaded rod before processing, the limiting plate is placed against both sides of the workpiece, which can maintain the stability of the workpiece during the bending process. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses a bending machine for producing curved parts of blister film.

[0019] Reference Figure 1-3 A bending machine for producing curved parts of blister film includes a base plate 1 and two curved blocks 2. The two curved blocks 2 are symmetrically arranged on both sides of the upper surface of the base plate 1. A groove is provided in the middle of the upper surface of the base plate 1. A rotating rod 3 is provided at both ends of the inner side of the groove. A connecting block is rotatably connected to both ends of the rotating rod 3. One side of the connecting block is fixedly connected to the inner wall of the groove. A first bending plate 4 is fixedly sleeved on the rod wall of one side of the rotating rod 3, and a second bending plate 5 is fixedly sleeved on the rod wall of the other side of the rotating rod 3. A transmission mechanism for driving the two rotating rods 3 to rotate is provided on the front side of the base plate 1.

[0020] Reference Figure 1-3 The transmission mechanism includes a gear 6 and a rack 8. The gear 6 is fixedly sleeved on the front end of the rotating rod 3. A crossbar 7 is provided above the two gears 6. The rack 8 is fixedly set on the lower surface of the crossbar 7 and located above the gear 6. The rack 8 is meshed with the gear 6. A round pin 10 is fixedly set on the front side of the middle end of the crossbar 7. A transmission rod 9 is rotatably sleeved on the middle end of the base plate 1. A lever 11 is fixedly sleeved on the front end of the transmission rod 9. A strip-shaped opening is opened on the rod wall of the lever 11. The front end of the round pin 10 passes through the strip-shaped opening. A motor 12 is fixedly set on the rear side of the base plate 1. The output end of the motor 12 is fixedly connected to one end of the transmission rod 9. An anti-detachment ring is fixedly sleeved on the end of the round pin 10 away from the crossbar 7 to prevent the round pin 10 from slipping out of the strip-shaped opening as much as possible.

[0021] Reference Figure 1-3 Both sides of the arc-shaped stop 2 are provided with limit plates 13. One end of the limit plate 13 is provided with a threaded hole. A threaded rod 14 is threadedly sleeved inside the threaded hole. One end of the threaded rod 14 is rotatably connected to the side wall of the arc-shaped stop 2. Limit holes are provided on both sides of the side wall of the limit plate 13 located at the threaded hole. A limit rod 15 is slidably sleeved inside the limit hole. One end of the limit rod 15 is fixedly connected to the side wall of the arc-shaped stop 2, so that the limit plate 13 can slide stably.

[0022] Reference Figure 1-3A fixing block 16 is fixedly installed at one end of the front side of the base plate 1. A square rod 17 is fixedly installed on the side of the fixing block 16 near the crossbar 7. A square hole is opened at the end of the crossbar 7 near the square rod 17. The square rod 17 is matched and inserted into the square hole, so that the crossbar 7 can move stably.

[0023] In this utility model, during use, the threaded rods 14 on both sides of the arc-shaped stop 2 are rotated, causing the threaded rods 14 to push the limiting plate 13 to slide along the limiting rod 15 until the distance between the two limiting plates 13 matches the width of the workpiece, completing the workpiece positioning preparation. Then, the motor 12 is started, and the output end of the motor 12 drives the transmission rod 9 to rotate in the middle of the base plate 1. The transmission rod 9 drives the front end lever 11 to rotate synchronously. The strip-shaped opening on the lever 11's rod wall cooperates with the round pin 10, pushing the round pin 10 to drive the crossbar 7 to move. The rack 8 on the lower surface of the crossbar 7 moves with the crossbar and meshes with the gear 6 at the front end of the two rotating rods 3, so that one rotating rod 3 drives the first bending plate 4 to rotate around the rotating rod 3 to a vertical state, and the other rotating rod 3 drives the second bending plate 5 to rotate around the rotating rod 3. When the shaft rotates to a horizontal position, the first bending plate 4, rotating vertically, squeezes the workpiece, and the arc-shaped surface of the arc-shaped stop 2 completes the bending of the workpiece. At the same time, the next batch of workpieces to be bent can be placed in advance above the second bending plate 5 in the horizontal position, realizing the operation of bending on one side and changing materials on the other, reducing the downtime for changing materials. When the first bending plate 4 completes the bending, the motor 12 rotates in the reverse direction, driving the transmission rod 9 and the lever 11 to move in the reverse direction. The round pin 10 pulls the crossbar 7 to reset, and the rack 8 drives the gear 6 on one side to rotate. The first bending plate 4 resets to the horizontal position, and the bent workpiece can be taken out. At the same time, the second bending plate 5 rotates to the vertical position to bend the pre-placed workpiece. This cycle continues to realize the alternating bending and material changing of the two stations, which significantly improves the production efficiency.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
