Abstract
Description
Technical Field
[0001] This utility model relates to the field of blister box processing technology, and in particular to an auxiliary device for blister box edge trimming and positioning. Background Technology
[0002] In the blister packaging industry, after the blister box is formed, there is often excess waste material left on its edges. This waste material needs to be removed through an edge trimming process to ensure the neatness of the blister box's appearance and its suitability for use. The precision of the edge trimming process directly affects the subsequent use of the blister box. For example, in fields such as food, pharmaceuticals, and electronics, where packaging sealing and dimensional accuracy are highly critical, if the edges of the trimmed blister box are uneven or the dimensional deviation is too large, it may lead to problems such as reduced packaging sealing and inability to accurately fit the matching cover, thereby affecting product quality and user experience. In the traditional blister box trimming process, positioning operations mostly rely on manual adjustment. With the advancement of automated production, some companies have introduced semi-automatic trimming equipment. However, the positioning auxiliary devices of existing equipment mostly use clamping or limiting in one direction, which is difficult to adapt to the positioning needs of blister boxes of different sizes and thicknesses. At the same time, after cutting, the blister box may bounce or shift due to the cutting force, requiring manual readjustment, which increases process time, reduces production efficiency, and affects the final product quality.
[0003] Therefore, it is necessary to provide a new auxiliary device for positioning and trimming the edges of blister packs to solve the above-mentioned technical problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an auxiliary device for trimming and positioning blister boxes.
[0005] The blister box trimming and positioning auxiliary device provided by this utility model includes: a base, a support plate, a clamping plate, a drive assembly, and a negative pressure nozzle. A cutter for cutting the blister box is installed on the top of the base, and a support plate for placing the blister box is installed on the top of the base. The top of the support plate is symmetrically provided with clamping plates for holding the blister box. A drive assembly is installed between the base and the support plate. The drive assembly drives the clamping plate to move, which is used to fix the blister box to be cut in the cutting area on the top of the support plate. The top of the support plate is symmetrically provided with negative pressure nozzles for fixing the cut blister box.
[0006] Preferably, the drive assembly includes a motor, a gear, and a gear post. The motor is fixedly connected to the top of the base, the gear is fixedly connected to the output end of the motor, and the gear post is equidistantly meshed with the outer wall of the gear. The shaft of the gear post is rotatably connected to the bottom end of the support plate.
[0007] Preferably, each toothed column has a toothed rack meshing on its bottom side, and the included angle between any two adjacent toothed racks is 90 degrees. Each toothed rack is fixedly connected to a push plate at the end away from the corresponding toothed column. Each push plate has a limit hole in its interior near the bottom. The bottom of the support plate is fixedly connected to a limit rod corresponding to the push plate. The other end of each limit rod passes through the corresponding limit hole and is slidably connected to its inner wall.
[0008] Preferably, each clamping plate is slidably connected to a corresponding push plate, and a guide rod is fixedly connected to the top of each clamping plate. The other end of each guide rod passes through the outer wall of the corresponding push plate. A spring is fitted on the outer wall of each guide rod. The bottom end of each spring is fixedly connected to the corresponding clamping plate, and the other end is fixedly connected to the corresponding push plate.
[0009] Preferably, the top of the support plate is symmetrically provided with clearance grooves corresponding to the push plate, and the clamping plates are all located above the clearance grooves, and their width is greater than the width of the clearance grooves.
[0010] Preferably, a negative pressure pump is fixedly connected to the top of the base, and the input end of the negative pressure pump is connected to a connecting pipe. The other end of the connecting pipe is connected to the bottom of the corresponding negative pressure nozzle.
[0011] Preferably, pressure sensors are fixedly connected to the side walls of the push plate.
[0012] Compared with related technologies, the blister box trimming and positioning auxiliary device provided by this utility model has the following beneficial effects: Employing a multi-directional synchronous clamping and positioning mechanism, the motor drives gears, pinions, and racks to move the push plate synchronously towards the center along the X and Y axes. This allows the clamping plate to push the blister box from multiple angles, ultimately aligning it with the center of the support plate and ensuring the blister box is precisely positioned within the cutting area. This multi-directional collaborative positioning method avoids the positioning deviations caused by traditional single-directional limiting, significantly reduces errors from manual visual adjustments, and substantially improves the edge flatness and dimensional accuracy of the blister box after trimming. The flexible clamping structure enables compatibility with blister boxes of different sizes and thicknesses. The clamping plate and the push plate are slidably connected, and the buffer structure composed of the guide rod and the spring can move upward along the axis and compress the spring when it contacts the edge of the blister box, so as to achieve flexible clamping through the spring force. This design can avoid damage to thin-walled or easily deformable blister boxes by rigid clamping, and can also adapt to the positioning requirements of blister boxes of different thicknesses. The pressure sensor on the side wall of the push plate can monitor the clamping pressure in real time. When the pressure reaches the preset threshold, the motor will stop automatically, ensuring that it can provide a stable and appropriate clamping force for blister boxes of different materials. There is no need to manually adjust the clamping parameters, which significantly improves the versatility of the equipment.
[0013] The design employs a dual fixation mechanism of mechanical clamping and negative pressure adsorption: the blister box is centered and fixed by the coordinated action of the clamping plate and the push plate, and the negative pressure pump generates negative pressure through the connecting pipe to adsorb the blister box from the bottom, forming a dual fixation of clamping and adsorption. This design effectively solves the problem of blister boxes bouncing or shifting due to cutting force in traditional equipment, thus avoiding positional deviation during cutting.

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.
[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0018] Please see Figures 1 to 5A blister box trimming and positioning auxiliary device is disclosed. The device includes: a base 1, a support plate 3, a clamping plate 4, a drive assembly, and negative pressure nozzles 5. A cutter 2 for cutting the blister box is mounted above the base 1. The support plate 3 for placing the blister box is mounted on the top of the base 1. Clamping plates 4 for holding the blister box are symmetrically arranged on the top of the support plate 3. A drive assembly is installed between the base 1 and the support plate 3, driving the clamping plates 4 to move and fix the blister box to be cut in the cutting area on the top of the support plate 3. Negative pressure nozzles 5 for fixing the cut blister box are symmetrically arranged on the top of the support plate 3. The drive assembly includes: a motor 6, a gear 7, and a toothed column 8. The motor 6 is fixedly connected to the top of the base 1. The output end of the motor 6 is fixedly connected to the gear 7. The outer wall of the gear 7 is equidistantly meshed with toothed columns 8. The shafts of the toothed columns 8 are rotatably connected to the bottom end of the support plate 3. Each toothed column 8 has a rack 9 meshing on its bottom side. The included angle between two adjacent racks 9 is 90 degrees. Each rack 9 is fixedly connected to a push plate 10 at the end away from the corresponding tooth post 8. Each push plate 10 has a limit hole 11 near the bottom. The bottom of the support plate 3 is fixedly connected to a limit rod 12 corresponding to the push plate 10. The other end of each limit rod 12 passes through the corresponding limit hole 11 and is slidably connected to its inner wall. Each clamping plate 4 is slidably connected to the corresponding push plate 10. Each clamping plate 4 is fixedly connected to a guide rod 13 at the top. Each guide rod 13 passes through the outer wall of the corresponding push plate 10. Each guide rod 13 has a spring 14 sleeved on its outer wall. The bottom end of each spring 14 is fixedly connected to the corresponding clamping plate 4, and the other end is fixedly connected to the corresponding push plate 10. The top of the support plate 3 is symmetrically provided with clearance grooves 15 corresponding to the push plate 10. Each clamping plate 4 is located above the clearance groove 15 and its width is greater than the width of the clearance groove 15. Each side wall of the push plate 10 is fixedly connected to a pressure sensor 17.
[0019] It should be noted that: Motor 6 is a reversible motor, a mature existing device. After starting motor 6, its output drives gear 7 to rotate. Gear 7 simultaneously meshes with multiple equally spaced toothed columns 8, driving all toothed columns 8 to rotate synchronously. During rotation, the toothed columns 8 drive the rack 9 below to translate through meshing. The rack 9 moves towards the center of support plate 3 along the X and Y axes respectively, and the push plate 10 fixed at its end moves synchronously. At this time, the limiting hole 11 at the bottom of push plate 10 slides along the limiting rod 12 at the bottom of support plate 3 to ensure that push plate 10 does not deviate during translation and maintains stable movement. Push plate 10 moves towards the center along the clearance groove 15 at the top of support plate 3, driving clamping plate 4 to move synchronously closer to the blister box. As push plate 10 continues to move, clamping plate 4 moves towards the center. Plate 4 first contacts the edge of the blister box. Through synchronous pushing in multiple directions, the blister box is gradually corrected to the center position of the support plate 3. The push plate 10 continues to move towards the center, and the end of the clamping plate 4 is subjected to a reaction force due to contact with the blister box. Since the clamping plate 4 is slidably connected to the push plate 10, and the top is penetrated by the guide rod 13, the clamping plate 4 slides upward along the axial direction of the guide rod 13, while compressing the spring 14 sleeved on the outside of the guide rod 13. The elastic force of the spring 14 reacts to the clamping plate 4, making its bottom tightly press against the surface of the blister box, achieving flexible clamping. When the edge of the blister box is completely in contact with the side wall of the push plate 10, the pressure sensor 17 on the side wall of the push plate 10 monitors the clamping pressure in real time. When the pressure reaches the preset threshold, the motor 6 stops rotating, and the blister box is stably fixed in the cutting area. Please see Figure 2 and Figure 4 A negative pressure pump 16 is fixedly connected to the top of the base 1. The input end of the negative pressure pump 16 is connected to a connecting pipe, and the other end of the connecting pipe is connected to the bottom of the corresponding negative pressure nozzle 5. It should be noted that the negative pressure pump 16 is an existing mature device. When the negative pressure pump 16 is started, it draws the inside of the negative pressure suction nozzle 5 to a negative pressure state through the connecting pipe. Since the negative pressure suction nozzle 5 is symmetrically distributed on the top of the support plate 3 and its outer rubber pad is in close contact with the bottom of the blister box, the blister box is firmly adsorbed on the support plate 3, further preventing the blister box from shifting due to the impact force of the cutter 2 during the trimming process.
[0020] The working principle of the blister box trimming and positioning auxiliary device provided by this utility model is as follows: When the device is in its initial state, the clamping plate 4 is positioned at the edge of the support plate 3 under the drive of the drive component, the clearance groove 15 is fully exposed, and the negative pressure suction nozzle 5 is in a non-working state; the operator places the blister box to be cut in the middle area of the support plate 3, ensuring that the bottom of the blister box is in contact with the surface of the support plate 3. After the motor 6 is started, the output end of the motor 6 drives the gear 7 to rotate. The gear 7 simultaneously meshes with multiple equally spaced toothed columns 8, driving all the toothed columns 8 to rotate synchronously. Since the shaft of the toothed column 8 is rotatably connected to the bottom end of the support plate 3, the toothed column 8 drives the rack 9 below to translate through meshing during rotation. Because the adjacent racks 9 are distributed at a 90-degree angle, the racks 9 move towards the center of the support plate 3 along the X-axis and Y-axis directions respectively, and the push plate 10 fixed at its end moves synchronously. At this time, the limiting hole 11 at the bottom of the push plate 10 slides along the limiting rod 12 at the bottom of the support plate 3 to ensure that the push plate 10 does not deviate during translation and maintains the stability of the movement. The push plate 10 moves towards the center along the clearance groove 15 at the top of the support plate 3, causing the clamping plate 4 located above the clearance groove 15 to move towards the blister box simultaneously. Since the width of the clamping plate 4 is greater than the width of the clearance groove 15, its bottom is always in contact with the surface of the support plate 3 to avoid sinking into the clearance groove 15. As the push plate 10 continues to move, the clamping plate 4 first contacts the edge of the blister box. Through synchronous pushing in multiple directions, the blister box is gradually corrected to the center position of the support plate 3 to ensure that the edge of the blister box to be cut is precisely aligned with the cutting trajectory of the cutter 2, thus completing the positioning. As the push plate 10 continues to move towards the center, the end of the clamping plate 4 experiences a reaction force due to contact with the blister box. Since the clamping plate 4 is slidably connected to the push plate 10, and its top passes through the push plate 10 via the guide rod 13, the clamping plate 4 slides upward along the axial direction of the guide rod 13, while simultaneously compressing the spring 14 sleeved outside the guide rod 13. The elastic force of the spring 14 reacts to the clamping plate 4, causing its bottom to tightly press against the surface of the blister box, achieving flexible clamping. When the edge of the blister box is completely in contact with the side wall of the push plate 10, the pressure sensor 17 on the side wall of the push plate 10 monitors the clamping pressure in real time. When the pressure reaches a preset threshold, the motor 6 stops rotating, and the blister box is stably fixed in the cutting area. After clamping is completed, the negative pressure pump 16 starts and draws the inside of the negative pressure suction nozzle 5 to a negative pressure state through the connecting pipe. Since the negative pressure suction nozzle 5 is symmetrically distributed on the top of the support plate 3 and its outer rubber pad is in close contact with the bottom of the blister box, the blister box is firmly adsorbed on the support plate 3, further preventing the blister box from shifting due to the impact force of the cutter 2 during the edge trimming process. Subsequently, the cutter 2 starts and moves downward, trimming the edge of the blister box along the preset trajectory, and the excess waste is separated. After the trimming is completed, the cutter 2 resets; the motor 6 rotates in the opposite direction, driving the rack 9 to move in the opposite direction through the gear 7 and the toothed column 8, and the push plate 10 and the clamping plate 4 reset to the edge of the support plate 3 simultaneously; when the clamping plate 4 is separated from the edge of the blister box, the spring 14 releases its elastic potential energy, pushing the clamping plate 4 to slide down along the guide rod 13 to reset; the negative pressure pump 16 is turned off, the negative pressure suction nozzle 5 releases its adsorption, the operator removes the trimmed blister box, places a new blister box to be trimmed, and repeats the above process to enter the next round of trimming operation.
