Technical Field

[0001] The utility model relates to the field of blister machines, in particular to a transmission adjustment mechanism of a blister machine frame. Background Art

[0002] Blister packaging is generally used for the packaging of drugs or foods. With the rapid development of the economy and the continuous improvement of people's living standards, higher requirements have been put forward for the production and use of blister packaging for packaged drugs and foods. Blister packaging generally consists of a plastic bottom cover and a covering aluminum film. Therefore, blister machines are generally sequentially provided with a forming device, a heat-sealing device, an indentation device, and a cutting device. Among them, there is also a conveying and feeding device between the forming device and the heat-sealing device to add the materials to be packaged into it. In addition, the aluminum film or other material films above are conveyed into the heat-sealing device for heat-sealing.

[0003] For example, Chinese invention patent CN112407452A discloses a high-speed flat blister machine. Paragraph 30 of its specification discloses: "The present invention provides a high-speed flat blister machine; including a plastic sheet heating device 5, a forming station 6, a forming traction device 107, a forming storage device 108, a heat-sealing station 7, a heat-sealing traction device 204, a heat-sealing storage device 205, a batch number indentation station 8, a punching traction device 9, a punching station 10, a punching manipulator 1101, and a finished product conveying device; a package width adjustment device for adjusting the offset of the plastic sheet in the width direction is provided at the feeding end of the plastic sheet heating device 5." Paragraph 39 of the specification discloses that "the batch number adjustment screw 811 and the indentation adjustment screw 813 can be driven to rotate forward and backward respectively through the batch number die position adjustment handle 810 and the indentation die position adjustment handle 812, so as to drive the displacement of the batch number and indentation station dies, so as to accurately print the batch number and the indentation line."

[0004] It can be seen that once the storage and specifications of the produced blisters change in the prior art, the molds need to be replaced accordingly, and the width adjustment has to be adjusted by horizontally moving the upper and lower molds to adjust the installation position, and the adjustment is relatively complicated.

[0027] Embodiment 1

[0028] The transmission and adjustment mechanism of the blister machine frame is as Figures 1 - 2 shown, including a frame 1, on which a plurality of processing devices 2 are sequentially arranged along the front and rear in the conveying direction. The processing device 2 includes a forming device, a heat sealing device, an indentation device, and a cutting device sequentially arranged along the conveying direction. Each processing device 2 includes a mounting seat 21; a plurality of transmission and adjustment devices are installed on the frame 1, and each transmission and adjustment device is in transmission connection with the mounting seat 21 for adjusting the position of the processing device 2 in the front and rear directions of the frame 1. The transmission and adjustment device includes an adjusting worm 3 extending in the left-right direction and a screw 4 extending in the front-rear direction. A worm gear 41 is arranged above or below the adjusting worm 3. The worm gear 41 is fixedly connected or integrally formed with the screw 4. A threaded section 31 is arranged on the adjusting worm 3. The threaded section 31 is in threaded cooperation with the worm gear 41. The adjusting worm 3 is connected with an adjusting handle or an adjusting power source for driving its rotation. When the adjusting worm 3 rotates, it drives the worm gear 41 to rotate; further includes a longitudinal support member 5. The longitudinal support member 5 moves synchronously with the mounting seat 21 along the axial direction of the adjusting worm 3. A nut 6 is installed in the longitudinal support member 5. The nut 6 is in threaded cooperation with the screw 4. When the screw 4 rotates, it drives the mounting seat 21 to move along the axial direction of the screw 4. Whether manually shaking the handle or automatically adjusting, it can play a role of precise and quantitative adjustment, which is convenient for the staff to operate.

[0029] Further, the adjusting power source can be connected to the main control in the same way. As long as the specifications are input, the adjustment of each processing device can be unified, which is more convenient.

[0030] Both ends of the longitudinal support member 5 are used for fixing to the frame 1. As an implementation manner, as Figure 4In it, guide rails 12 extending in the front-back direction are provided on both the left and right sides of the frame 1. The mounting seat 21 is slidably arranged on the guide rail 12. The mounting seat 21 is directly fitted and installed on the guide rail 12 in cooperation with the guide rail 12. When the adjusting worm 3 rotates, it drives the mounting seat 21 to move forward or backward along the guide rail 12. As another implementation manner, the mounting seat 21 is installed on the guide rail 12 through a slider, and this manner is not shown in the figure.

[0031] As one of the implementation manners, steps 11 are provided on both the left and right sides of the frame 1. Steps 11 are provided on the side of the frame 1. The steps 11 are fixedly connected to the frame 1 or integrally formed. One or more of the bearing seat 32, the guide rail 12, and the longitudinal support member 5 are fixedly installed above the steps 11 and are in contact with the steps 11 at the bottom. The steps 11 can be connected to the frame 1 or integrally formed, and the integrally formed manner can be milling and other processes.

[0032] A nut 6 is installed in the mounting seat 21. The nut 6 is in threaded cooperation with the screw rod 4. When the screw rod 4 rotates, it drives the longitudinal support member 5 to move along the axial direction of the screw rod 4.

[0033] The left and right ends of the adjusting worm 3 are installed on the frame 1 through the bearing seat 32. A longitudinal support member 5 is installed on the frame 1. The screw rod 4 is passed through and installed on the longitudinal support member 5 through a deep groove ball bearing 42. The longitudinal support member 5 restricts the movement of the screw rod 4 in the front-back direction.

[0034] A main shaft 7 is installed on the frame 1 in the front-back direction. The main shaft 7 passes through each processing device 2. The main shaft 7 is connected to a rotational power source. The rotational power source is generally a motor, and a device for increasing torque such as a speed reducer can be connected, or other conventional power sources that are easily conceivable by those skilled in the art can also be used.

[0035] Cams 71 for driving the mold to lift are arranged in the mounting seats 21 of multiple processing devices 2. The main shaft 7 is passed through the cams 71 to drive the cams 71 to rotate. The rotation of the cams 71 is generally used to drive the lower mold or the lower frame of the processing device to move up and down. When the convex surface of the cam is upward, the mechanism that needs to rise is lifted. When the concave surface of the cam 71 is upward, the mechanism descends. All mechanisms can drive the lifting through the transmission of the main shaft 7 and the cams 71 to achieve processing synchronization and processing interval synchronization. The specific structure of the processing device is a conventional technology that is easily known to those skilled in the art and will not be elaborated here.

[0036] As Figure 3 shown, a sprocket 72 is installed on the frame 1. The sprocket 72 is connected to the rotational power source through a chain. The rotation plane of the sprocket 72 is perpendicular to the main shaft 7. The sprocket 72 is installed on the frame 1 through a bearing 73.

[0037] The frame 1 includes a front frame 14 and a rear frame 15. A wall panel 13 is arranged between the front frame 14 and the rear frame 15. The main shaft 7 has multiple segments, and the multiple segments of the main shaft 7 are coaxial. Each two adjacent main shafts 7 are connected by splines or couplings. The main shaft 7 is composed of multiple segments to reduce the forming cost. By connecting, the strength of the main shaft 7 is increased. After coaxial connection, only one power source is required to ensure the torque of rotation after mutual connection, and the main shaft 7 can drive all the processing devices to perform the up-and-down displacement action.

[0038] A flange 74 is arranged on the wall panel 13, and the bearing 73 is installed in the flange 74.

[0039] As Figures 4 - 5 shown, each drive adjustment device is provided with an adjustment worm 3. Threaded segments 31 are arranged at the left and right ends of the adjustment worm 3. Both ends of the adjustment worm 3 are respectively engaged with a worm gear 41 to synchronously rotate the worm gears 41 on the left and right sides. Longitudinal supports 5 are respectively arranged on the front and rear sides of the mounting seat 21 of the processing device 2. The screw 4 sequentially passes through a longitudinal support 5 on one side, the mounting seat 21, and another longitudinal support 5.

[0040] Working principle: When the specifications of the product to be processed change, it is necessary to adjust the dimensions of each processing device on the frame 1. Generally, the processing device

[0041] includes a forming device, a heat-sealing device, an indentation device, and a punching device. There is a feeding and conveying device for adding internal materials between the forming device and the heat-sealing device. The feeding and conveying device is generally relatively long. Therefore, the frame is divided into a front frame 14 and a rear frame 15, which are connected by a conveying device. There will be a feeding device above the conveying device to add the product in the blister into the plastic shell below; the forming device forms the bottom plastic shell. After the feeding and conveying device adds materials, the heat-sealing device heat-seals and forms the upper material roll with the plastic. The main function of the indentation device is to press the production batch number and the easy-tear line, and the punching device cuts the continuous plastic shell. Its structure is well-known to those skilled in the art and will not be elaborated here. When the processing device 2 works, the main shaft 7 rotates to drive each cam thereon to rotate, and the cam 71 will cooperate with the mating wheel or other components above it to lift or lower the lower die of the processing device 2.

[0042] When the specifications of the blister to be processed change, the specifications and spacings of each set of molds are different. During installation, it is necessary to adjust the spacings between various processing devices. Therefore, it is necessary to adjust the transmission adjustment device of the processing device whose position needs to be adjusted. The adjustment worm 3 is connected with an adjustment handle or an adjustment power source that drives its rotation. The adjustment handle is operated manually, and the adjustment power source can be common means in this field such as an electric cylinder or a motor, which drives the adjustment worm 3 to rotate. When the adjustment worm 3 rotates, the threaded section 31 at its end also rotates accordingly, driving the worm wheel 41 connected to it to rotate. Since the worm wheel 41 is integrally or fixedly connected to the screw rod, the screw rod 4 also rotates. Nuts 6 that cooperate with the screw rod 4 are respectively arranged in the mounting seats 21, and the nuts are limited in position so that the nuts move synchronously with the mounting seats 21 in the front-back direction. The nuts 6 cooperate with the screw rod 4. When the screw rod 4 rotates, the nuts 6 will have a driving force to move along the axial direction of the screw rod 4. The axial direction of the screw rod 4 is limited by the longitudinal support member 5. Therefore, the nuts will drive the mounting seats 21 axially limited thereto to move back and forth, thereby realizing the adjustment of the left-right horizontal position of the processing device on the frame 1.
