Description

Technical Field

[0001] The utility model relates to the technical field of composite plastic strip processing, in particular to an equidistant cutting device for composite plastic strips. Background Technique

[0002] A composite plastic strip is a plastic strip composed of multiple materials, usually used in various industrial and daily life applications. They combine the excellent properties of different materials and can provide better strength, durability and corrosion resistance. The application of composite plastic strips in the pharmaceutical field is mainly reflected in aspects such as pharmaceutical packaging. Pharmaceutical packaging: Blister packaging: Composite plastic strips can be used in the blister packaging of pharmaceuticals to protect tablets from moisture, light and oxygen, and extend the shelf life of pharmaceuticals; Bottle sealing: Composite materials can be used as the sealing strips for medicine bottles to ensure the sealing and anti-counterfeiting of the medicines inside the bottles.

[0003] During the processing of composite plastic strips, cutting operations need to be performed on them. Generally, during processing, composite plastic strips are processed in large quantities. Therefore, during cutting, it is necessary to ensure equal length for each cut. However, for some existing cutting devices, although they can perform equidistant cutting with the help of automated equipment, it is very difficult to accurately control the feeding and cutting steps of composite plastic strips. Moreover, when the two steps are running, most are controlled by independent drive systems. In this way, it will greatly increase the processing operation cost and the operation difficulty.

[0004] Therefore, in view of the above existing problems, this technical solution proposes an equidistant cutting device for composite plastic strips. Content of the Utility Model

[0005] The purpose of the utility model is to provide an equidistant cutting device for composite plastic strips to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A device for equidistant cutting of composite plastic strip, comprising a strip conveying table and a cutting knife; the cutting knife is arranged above a position of the strip conveying table in a lifting manner for cutting the composite plastic strip conveyed on the strip conveying table. A break is provided on one side of the strip conveying table, and an automatic feeding mechanism is arranged at the break. The automatic feeding mechanism intermittently drives the composite plastic strip on the strip conveying table to transfer towards the lower part of the cutting knife, and the distance of each transfer is the same. A set of circulating lifting mechanisms is arranged directly above the cutting knife. The circulating lifting mechanisms control the cutting knife to move up and down to automatically cut off the composite plastic strip below it. The circulating lifting mechanisms are rotationally connected to the automatic feeding mechanism through a transmission connecting member. When the circulating lifting mechanisms operate, under the transmission of the transmission connecting member, the automatic feeding mechanism is intermittently controlled to drive the composite plastic strip on the strip conveying table to transfer towards the lower part of the cutting knife, thereby realizing the automatic equidistant supply of the composite plastic strip driven by the kinetic energy in the circulating lifting mechanisms. While realizing the automatic equidistant cutting of the strip, the conversion utilization rate of the kinetic energy of the device can be improved.

[0007] Compared with the prior art, the beneficial effect of the present utility model is that: through the transmission of the kinetic energy for driving the cutting knife to lift under the transmission of the transmission belt, connecting shaft, helical gear, and incomplete gear, the feeding dialing wheel is intermittently driven to rotate, and then in cooperation with the feeding support wheel, the composite plastic strip between the two is controlled to intermittently feed equidistantly, and then in cooperation with the cutting knife that circulates and falls, equidistant cutting is performed, realizing the automatic feeding and equidistant cutting of the composite plastic strip as a whole, and being energy-saving and efficient.

[0016] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0017] Please refer to Figures 1-4A composite plastic card strip equidistant cutting device comprises a card strip conveying platform 10 and a cutting knife 11; the cutting knife 11 is arranged in a lifting manner above a place of the card strip conveying platform 10, and is used to cut the composite plastic card strip conveyed from the card strip conveying platform 10; a fracture is opened on one side of the card strip conveying platform 10, and an automatic material feeding mechanism is arranged at the fracture, and the automatic material feeding mechanism intermittently drives the composite plastic card strip on the card strip conveying platform 10 to transfer toward the bottom of the cutting knife 11, and the transfer distance each time is the same; a group of circulating lifting mechanisms is arranged directly above the cutting knife 11, and the circulating lifting mechanism The cutting knife 11 is controlled to move up and down to automatically cut off the composite plastic card strip below it. The circulating lifting mechanism is rotatably connected to the automatic material feeding mechanism through a transmission connecting piece. When the circulating lifting mechanism is in operation, under the transmission of the transmission connecting piece, the automatic material feeding mechanism is intermittently controlled to drive the composite plastic card strip on the card strip conveying platform 10 to move toward the bottom of the cutting knife 11, thereby realizing the automatic equidistant supply of the composite plastic card strip driven by the kinetic energy in the circulating lifting mechanism, realizing the automatic equidistant cutting of the card strip, and improving the conversion utilization rate of the kinetic energy of the device.

[0018] In the embodiment of the present invention, a cutting knife lifting channel 12 is provided on the card strip conveying platform 10 directly below the cutting knife 11. When the cutting knife 11 cuts the composite plastic card strip, it enters the cutting knife lifting channel 12 to ensure sufficient cutting of the composite plastic card strip. A plurality of legs are evenly installed at the bottom of the card strip conveying platform 10 to maintain its stability.

[0019] In one embodiment of the present invention, the automatic material feeding mechanism includes a feed support wheel 13 and a feed toggle wheel 14 which are arranged at intervals on the upper and lower sides of the fracture. The feed support wheel 13 and the feed toggle wheel 14 are fixedly installed with a wheel axle 18 at the center. One side of the wheel axle 18 of the feed toggle wheel 14 is connected to the transmission connecting member outwardly. A card strip opening is provided between the relative circumferential side walls of the feed support wheel 13 and the feed toggle wheel 14. The composite plastic card strip to be cut is placed on the card strip conveying platform 10, and then passes through the card strip opening. Under the rotation of the feed support wheel 13 and the feed toggle wheel 14, it is gradually pushed to move toward the bottom of the cutting knife 11. The wheel axles 18 on the feed support wheel 13 and the feed toggle wheel 14 are positioned by rotating and fitting through a positioning sleeve rod 16. A support seat 17 with a trapezoidal structure is connected to the bottom of the positioning sleeve rod 16 to keep it stable.

[0020] A plurality of rubber teeth 15 are evenly installed on the circumferential outer wall of the feed toggle wheel 14. When the teeth 15 rotate to the opening of the card strip, they contact the card strip and simultaneously move the card strip backward. The top of the feed support wheel 13 contacts the bottom of the card strip. When the teeth 15 drive the card strip to transfer, the feed support wheel 13 rotates synchronously to reduce the resistance at the bottom of the card strip.

[0021] As a preferred embodiment of the present invention, the cyclic lifting mechanism includes a longitudinally distributed sliding base mounted above the strip conveyor table 10 through a bracket. On both sides inside the sliding base, a lifting block 32 is jointly slidably connected by two groups of sliders 33. The top of the cutting knife 11 is detachably mounted in the middle of the bottom of the lifting block 32. A connecting ball 31 is rotatably connected to the top of the lifting block 32. The top of the connecting ball 31 is connected to a swinging connecting block 27 through a telescopic member. On both sides of the swinging connecting block 27, swinging connecting rods 26 are rotatably connected. The end of the swinging connecting rod 26 far from the swinging connecting block 27 is connected to a rotating rod 23. One end of the rotating rod 23 is connected to a servo motor 24 fixed on the sliding base, and the other end of the rotating rod 23 is rotatably connected to a transmission connecting member. That is, when the servo motor 24 operates to drive the rotating rod 23 to rotate, it controls the swinging connecting rods 26 on both sides to drive the swinging connecting block 27 to swing. Then, under the connection of the telescopic member, it drives the connecting ball 31 to roll on the top of the lifting block 32 and simultaneously drives the lifting block 32 to move up and down, thereby controlling the lifting of the cutting knife 11 at the bottom of the lifting block 32 to cut the composite plastic strip on the strip conveyor table 10. At the same time, by adjusting the initial height of the lifting block 32 through the telescopic member, the stroke of each cyclic lifting of the cutting knife 11 can be adjusted, so as to cut strips of different thicknesses;

[0022] Specifically, a positioning block 25 is movably passed through the rotating rod 23 on the upper side of the sliding base. The bottom of the positioning block 25 is fixed on the top of the sliding base. The positioning block 25 is provided to keep the rotating rod 23 rotating smoothly;

[0023] Specifically, the telescopic member includes a screw rod 29 connected to the top of the connecting ball 31. The top of the screw rod 29 is threadedly connected to a screw cylinder 28. By rotating the screw rod 29, the position of its end portion placed inside the screw cylinder 28 is adjusted, thereby adjusting the overall length of the connecting ball 31 from the swinging connecting rod 26, and further adjusting the initial height of the cutting knife 11. At the same time, a locking nut 30 is threadedly connected to the screw rod 29 for limiting the rotation between the screw rod 29 and the screw cylinder 28.

[0024] As a preferred embodiment of the present invention, the transmission connecting member includes a helical gear 19 fixed to the end of the wheel shaft 18 on one side of the feeding dial 14. A one-way gear 20 is vertically meshed on one side of the helical gear 19. One side of the one-way gear 20 is connected to a connecting shaft 21. The end of the connecting shaft 21 is rotatably connected to the adjacent rotating rod 23 through a transmission belt 22. That is, when the servo motor 24 operates to drive the rotating rod 23 to rotate, under the connection of the transmission belt 22, it drives the connecting shaft 21 to rotate, and then controls the intermittent meshing rotation of the one-way gear 20 and the helical gear 19, thereby driving the feeding dial 14 to rotate, and thus controlling the automatic intermittent feeding of the strip;

[0025] By adjusting the meshing time of the incomplete gear 20 and the helical gear 19, it is ensured that the incomplete gear 20 and the helical gear 19 are in a non-meshing state when the cutting knife 11 descends. When the cutting knife 11 rises, the incomplete gear 20 and the helical gear 19 mesh to drive the feeding dial wheel 14 to rotate, thereby controlling the forward movement of the clamping strip, so as to realize the automatic equidistant cutting and equidistant feeding of the clamping strip;

[0026] A positioning sleeve is sleeved on the connecting shaft 21, and the bottom of the positioning sleeve is installed on the side wall of the clamping strip conveying table 10 through a connecting rod.

[0027] The working principle of the present utility model is as follows: At the idle place of the device, all the above-mentioned driving parts, which refer to power elements, electrical parts and the adapted power supply, are connected by wires, and the electrical connection is completed in the order of the working sequence among the electrical parts. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of the electrical control will be made. During operation, the plastic clamping strip to be cut is placed on the clamping strip conveying table 10, and then according to the thickness of the clamping strip, the screw 29 is rotated to adjust the initial height of the cutting knife 11 to the best. Then the servo motor 24 is started to drive the swing connecting rod 26 to rotate. Then, under the connection of the screw 29 and the screw barrel 28, the cutting knife 11 at the bottom of the lifting block 32 is continuously driven to move up and down. At the same time, under the drive of the transmission belt 22, the connecting shaft 21 is synchronously driven to rotate. The intermittent meshing of the helical gear 19 and the incomplete gear 20 drives the feeding dial wheel 14 to rotate. Then, by using the rotation support of the feeding teeth 15 on the feeding dial wheel 14 and the lower feeding support wheel 13, the automatic equidistant feeding of the clamping strip is controlled, and then the equidistant cutting is carried out in cooperation with the cutting knife 11.

[0028] The above has made a detailed description of the preferred embodiment of this patent, but this patent is not limited to the above embodiment. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of this patent.
