Description

Technical Field

[0001] This utility model specifically relates to the field of cutting and blanking technology for blister packaging boxes, and more specifically to a cutting and blanking device for blister packaging boxes. Background Technology

[0002] The cutting and blanking of blister packaging boxes refers to the process of cutting large sheets of plastic, after they have been vacuum-formed, into individual blister packaging boxes according to pre-designed dimensions and shapes. This process ensures that the dimensional accuracy and appearance quality of each box meet the requirements.

[0003] Traditional cutting methods often suffer from low precision, low efficiency, and complex operation. For example, manual cutting makes it difficult to ensure dimensional consistency and has low production efficiency. Some automatic cutting equipment is not adaptable to blister sheets of different thicknesses and materials, and is prone to uneven cuts and burrs. As the market demands for the quality and production efficiency of blister packaging boxes continue to increase, automated cutting devices have emerged. However, when traditional automatic cutting devices are cutting, the clamped material may sag, which can easily cause the material to tear automatically during cutting, resulting in rough edges and affecting the cutting quality.

[0004] A search revealed Chinese Patent Publication No. CN201922453862.0, which discloses an automatic cutting and unloading device for flexible adhesive sheets. The device includes a feeding mechanism on one side of the frame, a guiding mechanism, a suction mechanism, a clamping mechanism, and a cutting mechanism. The clamping mechanism has pneumatic fingers. The suction mechanism has a first linear module and a slide rail on both sides of the frame. An L-shaped plate is mounted on the first linear module, and a first lifting cylinder is located on one side of the first linear module. A suction head assembly is located at the lower end of the first lifting cylinder. The cutting mechanism is located between the guiding mechanism and the suction mechanism and includes a second linear module, a second lifting cylinder, and a cutting head. The second lifting cylinder is mounted on the second linear module, and a mounting block is located at its upper end. The cutting head is locked within the mounting block.

[0005] The cutting and unloading device in the aforementioned patent uses a suction head assembly to transport the product to the starting finger for clamping. Although the product is clamped and fixed at this time, it is not in a tensioned state and the product will sag. This will cause the cut lines to deviate when the product is cut, which cannot effectively guarantee the cutting quality and result in the product size not meeting the processing requirements. Utility Model Content

[0006] The purpose of this utility model is to provide a cutting and unloading device for blister packaging boxes. In this structure, the blister packaging box is transported between a moving plate and a supporting beam. The moving plate descends to clamp the product. At this time, the two carrier plates in the unloading assembly are horizontal to support the product and prevent it from sagging too much, which could cause tearing during cutting. The cutting drive assembly then moves the cutter between the supporting beam and the limiting plate to effectively cut the clamped product. The cut product falls onto the two carrier plates, and the push rod of the second electric push cylinder presses down, causing the connecting rod to rotate inward through the pressure rod and the deflection plate, thus transporting the cut product into the receiving rack. This solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A blister packaging box cutting and unloading device includes a receiving rack with a hollow interior. A clamping and cutting assembly is fitted onto the top end of the receiving rack. The clamping and cutting assembly includes a support frame fixedly mounted to the receiving rack. A first electric push cylinder is fixedly mounted on the top of the support frame. A movable plate is fixedly connected to the push rod of the first electric push cylinder. The movable plate is slidably mounted to the support frame via rollers at both ends. This ensures that the movable plate does not shift during lifting, thereby effectively guaranteeing the fit between the movable plate and the supporting beam.

[0009] A support beam is installed below the movable plate; both ends of the support beam are fixed to the support frame by bolts; a limiting plate is installed on the side of the support beam away from the support frame; a cutter is installed in the gap between the limiting plate and the support beam; the bottom of the cutter is slidably mounted on a slide rail; the slide rail is fixedly installed on the inner side of the bottom of the support frame; the cutter moves along the gap between the limiting plate and the support beam, thereby effectively ensuring that there is no deviation when cutting the sheet material, thus effectively ensuring the cutting quality of the sheet material and ensuring the processing dimensions of the sheet material;

[0010] As a further technical solution of this utility model, the cutter is movably mounted to the cutting drive assembly via a connecting shaft; the cutting drive assembly includes a second movable rod movably mounted to the cutter; the end of the second movable rod away from the cutter is movably connected to the first movable rod via a rotating shaft; the end of the first movable rod away from the second movable rod is movably connected to the end of the fixed crossbeam via a rotating shaft; the cutter moves linearly along the slide rail under the drive of the cylinder via the second movable rod, thereby achieving the cutting effect on the sheet material;

[0011] As a further technical solution of this utility model, the fixed crossbeam is fixedly installed at the bottom of one end of the receiving rack; a cylinder is movably installed at the top of the end of the fixed crossbeam away from the first movable rod through a bearing seat; the push rod of the cylinder is movably connected to the second movable rod through a fisheye joint.

[0012] As a further technical solution of this utility model, a feeding component is installed at the end of the receiving rack away from the clamping and cutting component; the feeding component includes an L-shaped plate fixedly installed with the receiving rack; two L-shaped plates are provided and arranged symmetrically; the top two ends of the L-shaped plates are respectively movably mounted with a rotating shaft via a bearing seat and a mounting block; a carrier plate is fixedly installed on the rotating shaft; a deflection plate is fixedly installed at the end of the rotating shaft that cooperates with the bearing seat; the deflection plate is inclined; a pressure rod is fixedly installed at the end of the deflection plate away from the rotating shaft; the L-shaped plate is fixedly installed with the top of the receiving rack via a screw, and the feeding component collects the cut sheets into the receiving rack.

[0013] As a further technical solution of this utility model, the pressure rod passes through the double round head grooves opened at both ends of the connecting rod; a baffle is fixedly installed at the end of the pressure rod away from the deflection plate; the connecting rod is driven to press down by the second electric push cylinder, thereby effectively realizing that the pressure rod in the double round head groove presses down the deflection plate at the same time, realizing the rotation of the shaft, thereby opening the two carrier plates and realizing the placement of the cut sheet into the receiving rack.

[0014] As a further technical solution of this utility model, the top of the connecting rod is fixedly installed with the second electric push cylinder; the second electric push cylinder is fixedly installed on the top of the protective cover; the protective cover is fixedly installed on the top of the receiving rack away from the clamping and cutting assembly.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In use, the large sheet of vacuum-formed material produced is conveyed between the moving plate and the supporting beam. The moving plate is driven to descend by the first electric push cylinder, so that the sheet is clamped and fixed by the moving plate and the supporting beam. At this time, the end of the clamped sheet away from the conveying mechanism falls onto the two carrier plates, which support the sheet and effectively reduce the sagging of the sheet.

[0017] 2. In this utility model, during cutting, the cylinder drives the second movable rod to move through the fisheye joint. The second movable rod is connected to the cutter through the coupling shaft. When the cylinder rod extends or retracts, the second movable rod drives the cutter to move linearly along the slide rail, thereby effectively cutting the clamped sheet. During cutting, the second movable rod simultaneously drives the first movable rod to rotate along the end of the fixed crossbeam, thereby effectively achieving a compensation effect and ensuring the cutting quality of the cutter.

[0018] 3. In this utility model, after the sheet material is cut, it falls onto the carrier plate. A second electric push cylinder drives a connecting rod to press down, achieving the engagement of the double round-headed grooves at both ends of the connecting rod with the middle of the pressure rod. This causes the deflection plate to rotate counterclockwise. The end of the deflection plate away from the pressure rod is fixedly installed with the rotating shaft, effectively causing the two carrier plates to flip inward. This allows the sheet material to be placed inside the receiving rack. Two baffles are provided at the opening of the receiving rack to prevent the sheet material from falling outside the receiving rack during unloading. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-8 In this embodiment of the utility model, a blister packaging box cutting and unloading device includes a receiving rack 1; the receiving rack 1 has a hollow interior; a clamping and cutting assembly 3 is fitted onto one end of the top of the receiving rack 1; the clamping and cutting assembly 3 includes a support frame 30 fixedly installed with the receiving rack 1; a first electric push cylinder 31 is fixedly installed on the top of the support frame 30; a moving plate 32 is fixedly connected to the push rod of the first electric push cylinder 31; the two ends of the moving plate 32 are slidably installed with the support frame 30 through rollers 33;

[0030] A support beam 34 is installed below the movable plate 32; both ends of the support beam 34 are fixedly installed to the support frame 30 by bolts; a limiting plate 35 is installed on the side of the support beam 34 away from the support frame 30; a cutter 36 is installed in the gap between the limiting plate 35 and the support beam 34; the bottom of the cutter 36 is slidably mounted on a slide rail 37; the slide rail 37 is fixedly installed on the inner side of the bottom of the support frame 30.

[0031] The cutter 36 is movably mounted to the cutting drive assembly 2 via a coupling shaft; the cutting drive assembly 2 includes a second movable rod 24 movably mounted to the cutter 36; the end of the second movable rod 24 away from the cutter 36 is movably connected to a first movable rod 23 via a rotating shaft; the end of the first movable rod 23 away from the second movable rod 24 is movably connected to the end of the fixed crossbeam 20 via a rotating shaft.

[0032] By adopting the above technical solution, during use, the large sheet of vacuum-formed material produced is conveyed between the moving plate 32 and the supporting beam 34. The first electric push cylinder 31 drives the moving plate 32 to descend, thereby clamping and fixing the sheet through the moving plate 32 and the supporting beam 34. At this time, the end of the clamped sheet away from the conveying mechanism falls onto the two carrier plates 42, which support the sheet and effectively reduce the sagging of the sheet.

[0033] The fixed crossbeam 20 is fixedly installed at the bottom of one end of the receiving rack 1; a cylinder 21 is movably installed at the top of the fixed crossbeam 20 away from the first movable rod 23 via a bearing seat; the push rod of the cylinder 21 is movably connected to the second movable rod 24 via a fisheye joint 22.

[0034] In this embodiment, a feeding component 4 is installed at the end of the receiving rack 1 away from the clamping and cutting component 3; the feeding component 4 includes an L-shaped plate 46 fixedly installed with the receiving rack 1; there are two L-shaped plates 46, which are arranged symmetrically; the top two ends of the L-shaped plate 46 are respectively movably mounted with a rotating shaft 43 through a bearing seat and a mounting block; a carrier plate 42 is fixedly installed on the rotating shaft 43; a deflection plate 44 is fixedly installed at the end of the rotating shaft 43 that cooperates with the bearing seat; the deflection plate 44 is inclined; a pressure rod 48 is fixedly installed at the end of the deflection plate 44 away from the rotating shaft 43.

[0035] By adopting the above technical solution, during the cutting process, the cylinder 21 drives the second movable rod 24 to move through the fisheye joint 22. The second movable rod 24 is connected to the cutter 36 through a connecting shaft. When the cylinder rod of the cylinder 21 extends or retracts, the second movable rod 24 drives the cutter 36 to move linearly along the slide rail 37, thereby achieving effective cutting of the clamped sheet. During the cutting process, the second movable rod 24 simultaneously drives the first movable rod 23 to rotate along the end of the fixed crossbeam 20, thereby effectively achieving a compensation effect and ensuring the cutting quality of the cutter 36.

[0036] In this embodiment, the pressure rod 48 passes through the double round head slots 45 opened at both ends of the connecting rod 41; a baffle is fixedly installed at the end of the pressure rod 48 away from the deflection plate 44.

[0037] The top of the connecting rod 41 is fixedly installed with the second electric push cylinder 40; the second electric push cylinder 40 is fixedly installed on the top of the protective cover 47; the protective cover 47 is fixedly installed on the top of the receiving rack 1 away from the clamping and cutting assembly 3.

[0038] By adopting the above technical solution, after the sheet is cut, it falls onto the carrier plate 42. The second electric push cylinder 40 drives the connecting rod 41 to press down, realizing the engagement between the double round head grooves 45 at both ends of the connecting rod 41 and the middle of the pressure rod 48, so that the deflection plate 44 rotates counterclockwise. The end of the deflection plate 44 away from the pressure rod 48 is fixedly installed with the rotating shaft 43, thereby effectively realizing the inward flipping of the two carrier plates 42. This allows the sheet to be placed into the receiving rack 1. Two baffles are set at the opening of the receiving rack 1 to prevent the sheet from falling outside the receiving rack 1 during unloading.

[0039] The working principle of this utility model is as follows: When in use, the large sheet of vacuum-formed material produced is transported between the moving plate 32 and the supporting beam 34. The first electric push cylinder 31 drives the moving plate 32 to descend, thereby clamping and fixing the sheet through the moving plate 32 and the supporting beam 34. At this time, the end of the clamped sheet away from the conveying mechanism falls onto the two carrier plates 42, which support the sheet and effectively reduce the sagging of the sheet.

[0040] During cutting, cylinder 21 drives the second movable rod 24 to move through the fisheye joint 22. The second movable rod 24 is connected to the cutter 36 through a coupling. When the cylinder rod of cylinder 21 extends or retracts, the second movable rod 24 drives the cutter 36 to move linearly along the slide rail 37, thereby effectively cutting the clamped sheet. During cutting, the second movable rod 24 simultaneously drives the first movable rod 23 to rotate along the end of the fixed crossbeam 20, thereby effectively achieving a compensation effect and ensuring the cutting quality of the cutter 36.

[0041] After the sheet is cut, it falls onto the carrier plate 42. The second electric push cylinder 40 drives the connecting rod 41 to press down, achieving the engagement between the double round head grooves 45 at both ends of the connecting rod 41 and the middle of the pressure rod 48. This causes the deflection plate 44 to rotate counterclockwise. The end of the deflection plate 44 away from the pressure rod 48 is fixedly installed with the rotating shaft 43, thus effectively achieving the inward flipping of the two carrier plates 42. This allows the sheet to be placed into the receiving rack 1. Two baffles are provided at the opening of the receiving rack 1 to prevent the sheet from falling outside the receiving rack 1 during unloading.

[0042] 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.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
