Description

Technical Field

[0001] This utility model relates to the field of packaging machines, and in particular to an automatic bag feeding and filling mechanism. Background Technology

[0002] As a core consumable in biomedical testing and pathological analysis, the surface cleanliness and anti-contamination performance of glass slides directly affect the accuracy of test results. In the glass slide manufacturing process, after slicing, vacuum packaging and sealing are required to isolate external moisture, dust, and microorganisms, ensuring the product's sterility during transportation and storage. High-end glass slides, such as fluorescently labeled slides and cell culture slides, have stringent requirements for packaging sealing, necessitating the use of multi-layer composite aluminum foil bags combined with vacuum heat-sealing technology to achieve long-term protection.

[0003] The current slide packaging process requires operators to manually place the boxed slides one by one into the packaging bag, which is labor-intensive and inefficient. In mass production scenarios, it can easily become a bottleneck in production capacity. Since human hands directly contact the inner wall of the packaging bag and the surface of the slides, fingerprints, sweat stains or microbial contamination may be introduced, leading to a decrease in product qualification rate. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides an automatic bag feeding and filling mechanism, which can effectively solve the technical problem of requiring manual bag filling.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An automatic bag feeding and bagging mechanism includes a base. The surface of the base is provided with a bag feeding assembly, a spreading assembly, and a bag filling assembly. The bag feeding assembly and the bag filling assembly are both connected to the spreading assembly. The bag feeding assembly includes a packaging hopper, a bag picking suction cup, and a bag placing suction cup. The packaging hopper is provided with a material picking opening facing the spreading assembly. The bag picking suction cup and the bag placing suction cup are located between the packaging hopper and the spreading assembly. The bag picking suction cup is rotatably connected to the base through a bag picking pneumatic swing arm. The bag placing suction cup is installed between the bag picking suction cup and the spreading assembly through a linear guide rail. The linear guide rail can drive the bag placing suction cup to reciprocate between the bag picking suction cup and the spreading assembly.

[0007] The opening assembly includes a disc and a closing push block. The disc is rotatably mounted in the machine base. The surface of the disc has several material openings, which are equidistantly distributed around the center of the disc. Four bag-supporting rods pass vertically through each material opening. The four bag-supporting rods are connected to the disc via spring swing arms. Under the action of the spring swing arms, the four bag-supporting rods move toward the four corners of the material opening. The material opening near the bag suction cup is the bag-opening station. The closing push block is mounted in the machine base via a linear drive guide rail and corresponds to the bag-opening station. The closing push block can push the spring swing arms away from the end with the bag-supporting rods by squeezing the drive guide rail, so that the ends of the spring swing arms with the bag-supporting rods move closer to each other. The bag-supporting rods can be paired and inserted into the packaging bag.

[0008] The bagging assembly includes an infeed platform, a feeding platform, and a pusher block. The infeed platform and the feeding platform are located on opposite sides of a disc. The end of the disc closest to the infeed platform and the feeding platform is the bagging station. The pusher block is aligned with the material opening in the bagging station. The pusher block is connected to the machine base via a pusher rail. When the pusher block moves, it pushes the product in the infeed platform through the material opening to the feeding platform and into the open packaging bag in the bagging station.

[0009] Furthermore, the bag-covering suction cups are provided in pairs or more, and each pair of bag-covering suction cups is connected to a linear guide rail via opening and closing claws. The bag-covering suction cups can adhere to both sides of the opening of the packaging bag, and the opening and closing claws can adjust the relative spacing between the bag-covering suction cups.

[0010] Furthermore, the opening and closing gripper includes symmetrically arranged horizontal arms, sliders, and telescopic cylinders. The slide surface of the linear guide rail is provided with an opening and closing guide rail. The horizontal arms are installed on the surface of the opening and closing guide rail via the slider. The two ends of the telescopic cylinder are respectively connected to the slider and the slide of the linear guide rail. The telescopic cylinder drives the horizontal arms to move closer or further away from each other along the opening and closing guide rail.

[0011] Furthermore, the extrusion drive guide rail includes a pressing cylinder and a lifting cylinder, and the closing push block includes an upper pressing block and a lower pressing block. The pressing cylinder, the lifting cylinder, and the upper pressing block are connected by a fixed plate. The lower pressing block is connected to the telescopic rod of the pressing cylinder. The pressing cylinder drives the lower pressing block to move along the fixed plate, so that the lower pressing block is close to the upper pressing block. The telescopic rod of the lifting cylinder contacts the machine base. The fixed plate is connected to the machine base through a lifting slide rail.

[0012] Furthermore, a reducer is mounted on the surface of the base, and the disc is connected to the reducer in a transmission connection. A drive motor and a rotation sensor are connected to the surface of the reducer, and the drive motor is connected to the reducer in a transmission connection. The rotation sensor is used to detect the rotation angle of the disc.

[0013] Furthermore, a limit push plate is provided at the end of the feeding platform away from the disc, and the limit push plate is connected to the machine base through a push-pull cylinder.

[0014] Furthermore, the size of the material dispensing opening of the packaging hopper is smaller than the size of the packaging bag, and a bag-pressing plate is provided inside the packaging hopper. The bag-pressing plate can move towards the material dispensing opening inside the packaging hopper by gravity.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the bag-grabbing suction cup and the bag-feeding suction cup work together with the linear guide rail to grab the packaging bag, and the bag opening is expanded synchronously by the four-way bag-supporting rod of the expansion component, replacing the manual action of opening the bag opening. The slide box is pushed into the packaging bag by the pushing block, replacing the manual bag-feeding action. The discrete manual actions are transformed into a continuous automated process, which greatly improves production efficiency. The entire process of mechanical suction cup grabbing the packaging bag, bag-supporting rod inserting into the bag body and pushing block loading the slide box is untouched by human hands, avoiding the risk of biological contamination.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The following is combined with Figures 1-6 The automatic bag feeding and filling mechanism of this utility model is described in detail below:

[0025] An automatic bag feeding and bagging mechanism includes a base 1. The surface of the base 1 is provided with a bag feeding assembly 2, a spreading assembly 3, and a bagging assembly 4. The bag feeding assembly 2 and the bagging assembly 4 are both connected to the spreading assembly 3. The bag feeding assembly 2 includes a packaging hopper 201, a bag picking suction cup 202, and a bag-filling suction cup 203. The packaging hopper 201 is provided with a material picking opening facing the spreading assembly 3. The bag picking suction cup 202 and the bag-filling suction cup 203 are located between the packaging hopper 201 and the spreading assembly 3. The bag picking suction cup 202 is rotatably connected to the base 1 through a bag picking pneumatic swing arm 209. The bag-filling suction cup 203 is installed between the bag picking suction cup 202 and the spreading assembly 3 through a linear guide rail 204. The linear guide rail 204 can drive the bag-filling suction cup 203 to reciprocate between the bag picking suction cup 202 and the spreading assembly 3.

[0026] The expansion assembly 3 includes a disc 304 and a closing push block 301. The disc 304 is rotatably mounted in the base 1. The surface of the disc 304 has several material openings 305, which are equidistantly distributed around the center of the disc 304. Four bag-supporting rods 302 pass vertically through each material opening 305. The four bag-supporting rods 302 are connected to the disc 304 via spring swing arms 303. Under the action of the spring swing arms 303, the four bag-supporting rods 302 respectively... The material opening 305 moves towards the four corners of the material opening 305. The material opening 305 near the end of the bag suction cup 203 is the bag-supporting station. The closing push block 301 is installed in the machine base 1 through the linear drive guide rail and corresponds to the bag-supporting station. The closing push block 301 can push the spring swing arm 303 away from the end of the bag-supporting rod 302 by squeezing the drive guide rail 7, so that the ends of the spring swing arms 303 with the bag-supporting rod 302 are close to each other, and the bag-supporting rod 302 can be paired and inserted into the packaging bag.

[0027] The bagging assembly 4 includes an infeed platform 5, a feeding platform 6, and a pusher block 401. The infeed platform 5 and the feeding platform 6 are located on opposite sides of the disc 304. The end of the disc 304 closest to the infeed platform 5 and the feeding platform 6 is the bagging station. The pusher block 401 is aligned with the material opening 305 in the bagging station. The pusher block 401 is connected to the machine base 1 via a pusher rail 402. When the pusher block 401 moves, it pushes the product in the infeed platform 5 through the material opening 305 into the feeding platform 6 and into the open packaging bag in the bagging station.

[0028] The bag-grabbing suction cup 202 and the bag-feeding suction cup 203 work together with the linear guide rail 204 to grab the packaging bag. The bag opening is simultaneously expanded by the four-way bag-supporting rod 302 of the expansion component 3, replacing the manual action of opening the bag opening. The slide box is pushed into the packaging bag by the pusher block 401, replacing the manual bag-feeding action. This transforms discrete manual actions into a continuous automated process, greatly improving production efficiency. The entire process of mechanical suction cup grabbing the packaging bag, bag-supporting rod 302 inserting into the bag body, and pusher block 401 loading the slide box is completely untouched by human hands, avoiding the risk of biological contamination.

[0029] The bag-covering suction cups 203 are provided in pairs or more. Each pair of bag-covering suction cups 203 is connected to the linear guide rail 204 via opening and closing grippers. The bag-covering suction cups 203 can adhere to both sides of the opening of the packaging bag. The opening and closing grippers can adjust the distance between the relative bag-covering suction cups 203. The opening and closing grippers drive the bag-covering suction cups 203 to move synchronously and symmetrically, ensuring that the force on both sides is uniform when the bag opening is opened, avoiding tearing or deformation of the bag opening caused by unilateral pulling. The opening and closing grippers include symmetrically arranged horizontal arms 205, sliders 206, and telescopic cylinders 207. The slide surface of the linear guide rail 204 is provided with an opening and closing guide rail 208. The horizontal arms 205 are installed on the surface of the opening and closing guide rail 208 via the sliders 206. The two ends of the telescopic cylinder 207 are connected to the sliders 206 and the slide of the linear guide rail 204, respectively. The telescopic cylinder 207 drives the horizontal arms 205 to move closer or further away from each other along the opening and closing guide rail 208, ensuring symmetrical opening of packaging bags of different sizes.

[0030] The extrusion drive guide rail 7 includes a pressing cylinder 701 and a lifting cylinder 702. The closing push block 301 includes an upper pressing block 3011 and a lower pressing block 3012. The pressing cylinder 701, the lifting cylinder 702, and the upper pressing block 3011 are connected by a fixing plate 704. The lower pressing block 3012 is connected to the telescopic rod of the pressing cylinder 701. The pressing cylinder 701 drives the lower pressing block 3012 to move along the fixing plate 704, so that the lower pressing block 3012 is close to the upper pressing block 3011. The telescopic rod of the lifting cylinder 702 contacts the machine base 1. The fixing plate 704 is connected to the machine base 1 through a lifting slide rail 703. The lifting cylinder 702 adjusts the height of the fixing plate 704 through the lifting slide rail 703 to adapt to the extrusion stroke requirements of spring swing arms 303 of different thicknesses. The lifting slide rail 703 ensures the vertical guidance of the extrusion action and eliminates the interference of lateral offset on the positioning accuracy of the support rod 302.

[0031] A reducer 8 is mounted on the surface of the base 1. The disc 304 is driven by the reducer 8. A drive motor and a rotation sensor are connected to the surface of the reducer 8. The drive motor is driven by the reducer 8, and the rotation sensor is used to detect the rotation angle of the disc 304 to ensure accurate alignment of the material opening 305 with the slide box and packaging bag. The rotation sensor monitors the angular deviation of the disc 304 in real time and provides feedback for correction, eliminating the cumulative error caused by gear backlash in traditional indexing plates and ensuring consistent positioning during continuous multi-station operation. The torque amplification function of the reducer 8 reduces the load on the drive motor and extends its service life.

[0032] The feeding platform 6 is provided with a limit push plate 9 at the end away from the disc 304. The limit push plate 9 is connected to the machine base 1 through a push-pull cylinder 10. The limit push plate 9 forms a physical stop structure at the end of the feeding platform 6 to ensure that the slide box is pushed to the final position inside the packaging bag.

[0033] The size of the material hopper 201 is smaller than the size of the packaging bag. A bag pressing plate 11 is provided inside the packaging hopper 201. The bag pressing plate 11 can move towards the material hopper opening inside the packaging hopper 201 by gravity, so that the packaging bags inside the packaging hopper 201 are always kept in a tightly stacked state, preventing the bag suction cup 202 from sucking up empty due to static electricity adhesion of the bags.

[0034] Working process: The packaging bag is placed into the packaging hopper 201 with the opening facing upwards. The bag-retrieving suction cup 202 adsorbs the packaging bag closest to the retrieval opening. The pneumatic swing arm 209 flips to make the packaging bag horizontal. The bag-attaching suction cup 203 adsorbs both ends of the packaging bag opening and opens the packaging bag opening through the opening and closing claws. The linear guide rail 204 drives the bag-attaching suction cup 203 to move to the bag-supporting station. The four bag-supporting rods 302 approach each other through the closing push block 301. After the bag-supporting rods 302 extend into the packaging bag, the closing push block 301 is released. Under the action of the spring swing arm 303, the bag-supporting rods 302 open and support the inside of the packaging bag. After the disc 304 rotates 180°, the supported packaging bag moves to the bag-filling station. The push block 401 pushes the glass slide box in the feeding platform 5 from the material opening 305 to the feeding platform 6 and into the packaging bag. At the same time, the glass slide box and the packaging bag are pushed away from the bag-supporting rods 302.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
