Description

Technical Field

[0001] This utility model relates to the field of medicine box cutting technology, and in particular to a medicine box cutting device that facilitates material feeding. Background Technology

[0002] In the pharmaceutical packaging production process, medicine boxes need to be cut to specific sizes and shapes to meet the needs of drug storage and transportation. With the improvement of automation levels, the operating efficiency, positioning accuracy, and material feeding smoothness of medicine box cutting devices have become key factors affecting the production line capacity. Currently, most medicine box cutting devices on the market can achieve basic cutting functions, but there is still room for improvement in areas such as automatic material feeding after cutting and compatibility with different specifications of medicine boxes. Especially in continuous production scenarios, problems such as low material feeding efficiency, easy damage to medicine boxes, and excessive manual intervention are more prominent, which restricts the continuity and stability of the overall production process. For example, a Chinese patent proposes a packaging box cutting device, patent publication number CN211541376U. When using the above patent, the packaging box is precisely cut by the cutting mechanism and the packaging box to be cut is transported to the cutting area by the conveying component, realizing the initial linkage between cutting and conveying. However, the above patent only solves the basic cutting and conveying problem of packaging boxes, and does not make special designs for the efficient unloading of the cut packaging boxes, nor does it consider the adaptive clamping requirements of medicine boxes of different sizes. The applicant discovered the following shortcomings when implementing the above plan: 1. The device does not have a dedicated feeding drive component. Therefore, the cut medicine boxes need to be removed from the cutting area manually or by natural sliding. This not only increases the intensity of manual labor, but also makes it easy for the medicine boxes to accumulate and bump during the sliding process, affecting the integrity of the medicine boxes' appearance. 2. The device lacks an adjustable synchronous clamping structure during use, and cannot flexibly adjust the clamping force and range according to the size of different medicine boxes. It can only be adapted to a single size of medicine box, and positioning deviation is prone to occur during clamping, which affects the cutting accuracy and reduces the practicality of the device.

[0003] Therefore, we propose a cutting device for medicine boxes that facilitates material feeding to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for medicine boxes that facilitates material feeding, thus solving the problems of inconvenient material feeding and poor adaptability of medicine boxes after cutting in the prior art.

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0012] Reference Figure 1-6 A cutting device for medicine boxes that facilitates material feeding includes a medicine box cutting machine 1, a guide plate 4 fixedly installed on one side of the medicine box cutting machine 1, and a discharge conveyor belt 3 provided on the side of the medicine box cutting machine 1 near the guide plate 4, and further includes: The top of the medicine box cutting machine 1 has an opening to form a working layer 6, and the middle of the working layer 6 has a straight groove. Two sets of symmetrical sliding grooves are opened on both sides of the working layer 6 near the straight groove, and a set of clamping plates 2 are slidably installed in the sliding grooves. The middle of the medicine box cutting machine 1 is hollowed out and a housing 8 is fixedly installed at the bottom. The housing 8 is equipped with a clamping drive assembly 5. The clamping drive assembly 5 is provided with two sets of sliding bases 17, and the tops of the two sets of sliding bases 17 are respectively connected to two sets of clamping plates 2. A feeding assembly 7 is installed at the middle of the top of the housing 8. A swing arm 13 is provided inside the feeding assembly 7, and one end of the swing arm 13 extends to the straight slot in the middle of the working layer 6. Furthermore, the unloading assembly 7 also includes a mounting base 9, a swing rod 10, and a rotating rod 11. An arched mounting base 9 is fixedly installed at the top of the middle part of the housing 8. The swing rod 10 is rotatably installed on one side of the mounting base 9, and the rotating rod 11 is rotatably installed at the end of the mounting base 9 away from the swing rod 10. By setting an arched mounting base at the top of the middle part of the housing and rotatably installing the swing rod and the rotating rod on both sides of the mounting base, a symmetrical and stable support structure is formed. This provides a reliable fulcrum for the subsequent installation of the swing arm, and the mechanical properties of the arched structure disperse the force during the unloading process, preventing the mounting base from deforming due to long-term stress. At the same time, the rotatable connection ensures the flexible movement of the swing rod and the rotating rod, laying a structural foundation for the smooth execution of the unloading action. Furthermore, a first motor 12 is fixedly installed on the side of the mounting base 9 near the rotating rod 11, and the output shaft of the first motor 12 is fixedly installed together with the rotating rod 11. By fixing the first motor on the side of the mounting base near the rotating rod and directly connecting the output shaft of the first motor to the rotating rod, direct power transmission is achieved, reducing energy loss of intermediate transmission components and improving power transmission efficiency. At the same time, the integrated installation of the motor and the rotating rod simplifies the transmission structure, reduces assembly difficulty, and the first motor can control the rotation speed and rotation angle of the rotating rod, providing power guarantee for the control of the feeding action. Furthermore, a swing arm 13 is hinged to one end of the rotating rod 11, and the middle part of the swing arm 13 is hinged to the swing rod 10. The end of the swing arm 13 near the working layer 6 is curved. By hinged one end of the rotating rod to the swing arm, and the middle part of the swing arm to the swing rod, a double-fulcrum lever transmission structure is formed. The rotation of the rotating rod can drive the swing arm to swing flexibly around the swing rod through the hinge point, which amplifies the transmission stroke and ensures that one end of the swing arm can form a sufficient swing amplitude at the straight slot of the working layer to complete the unloading action. The end of the swing arm near the working layer is set to be curved to match the shape of the medicine box, avoiding scratching or squeezing the medicine box during unloading, and at the same time, it can push the cut medicine box from the working layer to the discharge conveyor belt. Furthermore, the clamping drive assembly 5 includes slide rods 16, sliding bases 17, and racks 18. A set of slide rods 16 is fixedly installed on each of the two sides inside the housing 8, and two sets of symmetrical sliding bases 17 are slidably installed between the two sets of slide rods 16. A set of racks 18 is fixedly installed on each obliquely symmetrical side of the two sets of sliding bases 17. Two sets of support rods are fixedly installed at the top of each of the two sets of sliding bases 17, and the other ends of the two sets of support rods are fixedly connected to the corresponding clamping plates 2. By fixing slide rods on both sides inside the housing and slidably installing two racks 18 between the two sets of slide rods... The symmetrical sliding bases are guided by sliding rods, ensuring that the sliding bases can only move in a straight line along the direction of the sliding rods, thus avoiding deviation during clamping. The two sets of sliding bases are directly connected to the clamping plate through support rods, realizing synchronous movement between the clamping plate and the sliding bases. The obliquely symmetrical rack structure provides the structural premise for the subsequent gear-driven synchronous movement of the two sets of clamping plates in opposite directions. At the same time, the support rods allow the motion of the sliding bases to be transmitted to the clamping plate, ensuring the synchronicity and stability of the clamping action and improving the positioning effect during medicine box cutting. Furthermore, a second motor 14 is fixedly installed in the middle of the housing 8, and a gear 15 that meshes with two sets of racks 18 is fixedly installed on the output shaft of the second motor 14. By fixing the second motor in the middle of the housing and installing a gear that meshes with two sets of racks on the output shaft of the motor, the meshing transmission characteristics of the gear and rack are utilized to realize the synchronous reverse movement of two sets of clamping plates driven by a single motor, which simplifies the drive structure and reduces the manufacturing cost of the equipment. The meshing of the gear and the two sets of racks has the advantages of stable transmission ratio and smooth operation. The second motor can adjust the opening and closing range and clamping force of the two sets of clamping plates by controlling the forward and reverse rotation and speed of the gear, adapting to medicine boxes of different specifications and sizes, improving the versatility of the device. At the same time, the motor-driven method replaces manual clamping, reducing labor intensity and improving clamping efficiency and the degree of automation of cutting operations. In summary: First, the second motor 14 is started. The output shaft of the second motor 14 drives the gear 15 to rotate. Since the gear 15 meshes with the two sets of obliquely symmetrical racks 18, the rotation of the gear 15 will be converted into the opposite linear motion of the two sets of racks 18. The racks 18 are fixed on the two sets of sliding bases 17 respectively. Therefore, the two sets of sliding bases 17 will slide synchronously in opposite directions along the slide rods 16 on both sides inside the housing 8. The support rod at the top of the sliding base 17 moves synchronously with the sliding base 17, thereby driving the two sets of clamping plates 2 connected to the support rod to slide along the grooves on both sides of the working layer 6. When the two sets of clamping plates 2 are close to each other, they clamp and fix the medicine box; when they are far apart, they release the clamp. Through this linkage, the medicine box is stably positioned on the working layer 6, providing a reliable fixing effect for subsequent cutting operations. At the same time, the opening and closing range and clamping force of the clamping plates 2 can be changed by adjusting the forward and reverse rotation and speed of the second motor 14 to adapt to different specifications of medicine boxes. After the medicine box is positioned, the medicine box cutting machine 1 starts the cutting operation (the cutting action is performed by the cutting mechanism built into the equipment, focusing on the linkage between positioning and feeding). After the cutting is completed, the first motor 12 is started, and the output shaft of the first motor 12 directly drives the rotating rod 11 on the mounting base 9 to rotate. Since one end of the rotating rod 11 is hinged to the swing arm 13, and the middle of the swing arm 13 is hinged to the swing rod 10 on the other side of the mounting base 9, a double-fulcrum lever transmission structure is formed. The rotation of the rotating rod 11 is transmitted to the swing arm 13 through the hinge point, causing the swing arm 13 to swing flexibly around the swing rod 10, amplifying the transmission stroke, and allowing the swing arm 13 to extend to the end of the straight slot at the working layer 6 to form a sufficient swing amplitude. The end of the swing arm 13 near the working layer 6 is curved, which can conform to the outline of the medicine box during the swing process, avoiding scratching or squeezing the medicine box. At the same time, it pushes the cut medicine box from the working layer 6 to the discharge conveyor belt 3. After the discharge conveyor belt 3 is started, it transports the medicine box pushed on it towards the guide plate 4. The guide plate 4 guides the medicine box and prevents the medicine box from deviating during the conveying process, so that the medicine box is output from the equipment in an orderly manner, completing the entire cutting and unloading process.
