Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a capping mechanism for a case opener. Background Technology

[0002] With the rapid development of logistics and e-commerce, automated cardboard packaging production lines are increasingly widely used across various industries. As the first step in the production line, the fully automatic carton erector's main function is to automatically open and shape flat cardboard and fold the bottom. After the carton is formed, the top flap (leaf) usually needs to be folded and flattened immediately to facilitate subsequent processes such as tape sealing or packing. The stability of this step directly determines the final packaging quality.

[0003] However, in existing carton erecting machine structures, there is often a lack of a stable clamping mechanism for the carton itself when it is conveyed to the capping station. Traditional equipment usually relies solely on the friction of the conveyor belt at the bottom or simple guide rails fixed on both sides to restrict the position of the carton. Because the carton itself is lightweight and the material has a certain degree of elasticity, when the capping robotic arm at the top descends and applies a folding force to the cap, the carton is very prone to displacement, shaking, or even tilting under the force.

[0004] This unstable state can lead to a significant decrease in the alignment accuracy of the capping action, resulting in misalignment, excessive gaps, or uneven overlap of the folded caps. This not only seriously affects the flatness of the packaging appearance but may even cause equipment failure and shutdown due to cap jamming, failing to meet the requirements of modern production lines for high efficiency and high pass rate.

[0005] Therefore, this utility model proposes a capping mechanism for a box opener to address the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a capping mechanism for a case opener, aiming to improve the existing technology where the capping mechanism for a case opener lacks the case clamping and positioning function, and the case is prone to shaking, displacement or tipping during the capping operation, resulting in inaccurate folding and alignment of the cap, poor sealing quality and easy jamming failure.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a capping mechanism for a case opener, comprising: a base and a support frame fixedly connected to the top of the base; and a drive motor, a two-way lead screw, a moving block, a guide rod, a guide block, a connecting plate, a support block, a stabilizing block, a first capping motor, a first capping frame, a second capping motor, and a second capping frame.

[0008] A drive motor is fixedly installed inside the base. A bidirectional lead screw is fixedly connected to the output end of the drive motor. A moving block is threadedly connected to the outer wall of the bidirectional lead screw. A guide rod is fixedly installed inside the base and next to the bidirectional lead screw. A guide block is slidably connected to the outer wall of the guide rod. A connecting plate is fixedly connected between the moving block and the guide block.

[0009] A support block is fixedly connected to the top of the connecting plate. The top of the support block passes through a through hole opened at the top of the base and extends to the top of the base. A stabilizing block is fixedly connected to the top of the support block. A first cover pressing motor is fixedly installed on the top of the support frame. A first cover pressing frame is fixedly connected to the output end of the first cover pressing motor. A second cover pressing motor is fixedly installed on the bottom surface of the top crossbeam of the support frame. A second cover pressing frame is fixedly connected to the output end of the second cover pressing motor.

[0010] Preferably, the outer walls of both sides of the base are provided with stabilizing grooves, and the outer walls of both sides of the base are also fixedly installed with first electric push rods. An installation block is slidably connected inside the stabilizing groove, and one side of the installation block is fixedly connected to the telescopic end of the first electric push rod.

[0011] Preferably, a fixing plate is fixedly connected to the top of the mounting block, a second electric push rod is fixedly installed on one side of the fixing plate, and a clamping plate is fixedly connected to the telescopic end of the second electric push rod.

[0012] Preferably, a rubber stabilizing pad is fixedly connected to one side of the stabilizing block and one side of the clamping plate.

[0013] Preferably, the two ends of the bidirectional lead screw are rotatably connected to the inner wall of the base via bearings, and the threads on both sides of the bidirectional lead screw have opposite directions; the number of moving blocks is two, and they are symmetrically distributed about the center point of the bidirectional lead screw.

[0014] Preferably, the guide rod and the bidirectional lead screw are distributed in parallel, and the number of the guide block, the connecting plate, the support block and the stabilizing block are all set to two corresponding to the number of the moving block.

[0015] Preferably, there are two first capping motors, which are respectively fixedly installed on the two sides of the top of the support frame; the two ends of the first capping frame are respectively fixedly connected to the output ends of the two first capping motors.

[0016] Preferably, there are two second capping motors, which are respectively fixedly installed on both sides of the bottom surface of the top crossbeam of the support frame; the two ends of the second capping frame are respectively fixedly connected to the output ends of the two second capping motors.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem in the prior art that the box body is prone to positional deviation or unstable fixation after being transported to the position, resulting in inaccurate cap alignment, by setting a bidirectional lead screw assembly driven by a motor inside the base and linking it with the stabilizing block protruding from the top to achieve synchronous opposite movement. It achieves the technical effect of automatically centering and clamping the box body in the width direction and ensuring that the box body is always located on the center line of the work station, thereby improving the capping accuracy.

[0019] 2. This utility model solves the problem that existing technologies are difficult to adapt to boxes of different lengths or lack longitudinal fixation, which can cause the boxes to tilt forward or backward. It achieves the technical effect of being able to flexibly adjust to adapt to boxes of various sizes and forming a multi-directional stable support in conjunction with the bottom clamping mechanism, effectively preventing the boxes from shaking or tilting during the pressing process.

[0026] 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.

[0027] Please refer to Figures 1 to 4 This utility model provides a capping mechanism for a carton opener, which aims to solve the structural defect problem in the prior art where the carton lacks multi-directional stable clamping during capping operations, causing the carton to easily shake or tilt during the process of the robotic arm pressing and folding the cap, thus affecting the flatness of the capping and the quality of the carton sealing.

[0028] like Figure 1 and Figure 2 As shown, the capping mechanism for the case opener includes a base 1 and a support frame 2 fixedly connected to the top of the base 1. The base 1 serves as the mounting base for the entire device and accommodates the internal drive components. The support frame 2 provides a support mounting position for the top capping components and is arranged in a U-shape above the base 1.

[0029] To achieve centering and clamping of the box width, a drive motor 3 is fixedly installed inside the base 1. A bidirectional lead screw 301 is fixedly connected to the output end of the drive motor 3. Both ends of the bidirectional lead screw 301 are rotatably connected to the inner wall of the base 1 via bearings, and the threads on both sides of the bidirectional lead screw 301 have opposite directions. Two moving blocks 302 are threadedly connected to the outer wall of the bidirectional lead screw 301. These two moving blocks 302 are symmetrically distributed about the center point of the bidirectional lead screw 301. A guide rod 303 is fixedly installed inside the base 1, beside the bidirectional lead screw 301. The guide rod 303 is parallel to the bidirectional lead screw 301. A guide block 304 is slidably connected to the outer wall. A connecting plate 305 is fixedly connected between the moving block 302 and the guide block 304. A support block 306 is fixedly connected to the top of the connecting plate 305. The top of the support block 306 passes through the through hole 307 opened on the top of the base 1 and extends to the top of the base 1. A stabilizing block 308 is fixedly connected to the top of the support block 306. The bidirectional lead screw 301 is driven to rotate by the drive motor 3, which can drive the moving block 302 to move the connecting plate 305 and the support block 306 synchronously, thereby causing the two stabilizing blocks 308 on the top of the base 1 to move closer or further away from each other, so as to clamp and fix the two sides of the bottom of the box.

[0030] A component for performing the capping action is provided on the support frame 2. A first capping motor 4 is fixedly installed on the top of the support frame 2. The output end of the first capping motor 4 is fixedly connected to a first capping frame 401. A second capping motor 402 is fixedly installed on the bottom surface of the top crossbeam of the support frame 2. The output end of the second capping motor 402 is fixedly connected to a second capping frame 403. The first capping frame 401 and the second capping frame 403 are both located inside the space enclosed by the support frame 2, and are used to flip and close the long side cap and the short side cap of the box respectively.

[0031] The base 1 has stabilizing grooves 5 on both outer walls, which extend along the length of the base 1. First electric push rods 309 are fixedly installed on both outer walls of the base 1. Mounting blocks 310 are slidably installed inside the stabilizing grooves 5, and one side of the mounting block 310 is fixedly connected to the telescopic end of the first electric push rod 309. By activating the first electric push rod 309, the mounting block 310 can be driven to reciprocate along the stabilizing grooves 5, thereby adjusting the longitudinal position of the entire side clamping assembly to adapt to... For conveying boxes of different lengths or bypassing the box conveying path, a fixing plate 311 is fixedly connected to the top of the mounting block 310. A second electric push rod 312 is fixedly installed on one side of the fixing plate 311. A clamping plate 313 is fixedly connected to the telescopic end of the second electric push rod 312. When the mounting block 310 moves to the predetermined position, the second electric push rod 312 is activated to push the clamping plate 313 to extend inward and press against the front and rear outer walls of the box, forming a multi-directional stable clamping structure with the stabilizing block 308 above the base 1.

[0032] Meanwhile, in order to protect the surface of the box and increase the stability of clamping, rubber stabilizing pads 6 are fixedly connected to one side of the stabilizing block 308 and one side of the clamping plate 313. The rubber stabilizing pads 6 are soft and have a high coefficient of friction, which can increase the friction with the surface of the box during clamping, prevent the box from slipping, and avoid direct contact between hard metal parts and the box, causing scratches or indentations. As for the specific selection and control circuit connection of the drive motor 3, the first electric push rod 309, the second electric push rod 312, the first cover motor 4 and the second cover motor 402, those skilled in the art can use conventional servo motors, linear modules or PLC control systems according to the actual load requirements and control logic, which will not be elaborated here.

[0033] As a preferred embodiment, in order to ensure the synchronization and centering accuracy of the clamping mechanisms on both sides, the two ends of the bidirectional lead screw 301 are rotatably connected to the inner wall of the base 1 through bearings, and the threads on both sides of the bidirectional lead screw 301 are opposite in direction, so that when the drive motor 3 drives the bidirectional lead screw 301 to rotate in one direction, the moving blocks 302 located on both sides can simultaneously move towards the center or separate to both sides. In addition, the number of moving blocks 302 is set to two, and they are symmetrically distributed about the center point of the bidirectional lead screw 301, so as to ensure that the box is always clamped on the center line of the base 1, which facilitates the precise alignment of the subsequent capping mechanism.

[0034] As another preferred embodiment, in order to improve the smoothness of the movement of the moving block 302 and the load-bearing capacity, the guide rod 303 and the bidirectional lead screw 301 are distributed in parallel. The two ends of the guide rod 303 are fixedly connected to the inner wall of the base 1. The number of guide blocks 304, connecting plates 305, support blocks 306 and stabilizing blocks 308 are all set to two corresponding to the moving block 302. The guide rod 303 shares the lateral force generated during the movement, avoids the lead screw from bearing excessive radial load, and extends the service life of the mechanism.

[0035] In another preferred embodiment, in order to achieve efficient folding of the long side cover, the number of first cover pressing motors 4 is set to two, and they are respectively fixedly installed on the two sides of the top of the support frame 2. The two ends of the first cover pressing frame 401 are respectively fixedly connected to the output ends of the two first cover pressing motors 4. The dual motor drive can provide greater torque, ensuring that the carton cover of thicker or harder materials can also be folded flat.

[0036] As another preferred embodiment, in order to achieve reliable folding of the short side cover and avoid mechanical interference, the number of second cover pressing motors 402 is set to two, and they are respectively fixedly installed on both sides of the bottom surface of the top crossbeam of the support frame 2. The two ends of the second cover pressing frame 403 are respectively fixedly connected to the output ends of the two second cover pressing motors 402. This layered motor layout makes the first cover pressing frame 401 responsible for folding the long side and the second cover pressing frame 403 responsible for folding the short side spatially independent, which makes it easy for the control system to control the action sequence of the two sets of cover pressing frames separately and prevent action conflicts.

[0037] Working principle: When the box needs to be capped, the box to be processed is first transported to the base 1 by an external conveying device. Then, the drive motor 3 inside the base 1 is started, and its output end drives the bidirectional lead screw 301 to rotate. Since the threads on both sides of the bidirectional lead screw 301 turn in opposite directions, the rotation will drive the two moving blocks 302 on the outer wall to move closer to each other. The moving blocks 302 drive the two support blocks 306 on the connecting plate 305 to move stably along the guide rod 303, so that the support blocks 306 drive the top stabilizing block 308 to slide along the through hole 307 and move closer to each other, thereby achieving the centering and pressing support of both sides (width direction) of the bottom outer wall of the box.

[0038] Simultaneously, based on the length and position of the enclosure, the first electric push rods 309 on both sides of the base 1 are activated. Their telescopic ends drive the mounting block 310 to move longitudinally along the stabilizing slide 5, adjusting the side clamping assembly to the side corresponding to the enclosure. After longitudinal positioning is completed, the second electric push rod 312 is activated, and its telescopic end pushes the clamping plate 313 to extend inward until it contacts the front and rear outer walls of the enclosure. Through the multi-directional angle clamping of the stabilizing block 308 and the clamping plate 313, and with the addition of the rubber stabilizing pad 6 to increase friction, the enclosure is ensured to remain absolutely stable during the subsequent capping process, avoiding shaking and tilting.

[0039] After the box is stably supported, the capping operation begins: First, the control system activates two second capping motors 402, driving the second capping frame 403 to rotate and fold the short side caps at the front and back of the box. Once the short side caps are folded into place, the two first capping motors 4 are activated, driving the first capping frame 401 to rotate and flip and press the long side caps on the left and right sides of the box, thus completing the orderly sealing of the four caps. After the operation is completed, each clamping and capping mechanism reverses and resets, and the box is output to the next process by the conveyor equipment.
