Description

Technical Field

[0001] This utility model relates to the field of mechanical adjustment and plastic bag sealing machine technology, and in particular to a bidirectional adjustment mechanism for a sealing machine based on a clutch mechanism. Background Technology

[0002] Plastic bag sealing machines, also known as plastic bag sealing machines or heat sealing machines, are indispensable key equipment in the plastic packaging industry. Their core principle lies in heating heat-resistant pressing components using electric heating elements, applying hot pressure to the plastic film placed between the pressing components, causing the contact surfaces to melt and eventually cool and solidify, thus sealing the opening of the plastic bag. In practical applications, to accommodate plastic bags of different widths, sealing machines typically require precise position adjustment of the symmetrically arranged heat sealing blades on both sides. Existing technologies commonly use bidirectional lead screws to synchronously adjust the positions of the heat sealing blades on both sides to ensure symmetry, such as the technical solution disclosed in Chinese Patent Publication No. CN223131527U.

[0003] However, this existing technology, which relies on bidirectional lead screw synchronous adjustment, has certain drawbacks. Over long-term use, the bidirectional lead screw may be affected by various factors such as wear, manufacturing precision deviations, and uneven force, causing its synchronous adjustment function to gradually fail, resulting in the position adjustment of the two heat-sealing blades no longer being precisely synchronized. Specifically, when one heat-sealing blade is adjusted to a preset position, the other heat-sealing blade, which should maintain symmetry, may shift in relative position. Once this shift occurs, because the bidirectional lead screw simultaneously moves both heat-sealing blades, it is difficult for the user to fine-tune the shifted blade independently without moving the already correctly positioned blade. This limitation of not being able to adjust independently directly leads to a decrease in the sealing quality of plastic bags by the heat-sealing machine, affecting production efficiency and product qualification rate. To address these issues, the existing technology urgently needs improvement. Utility Model Content

[0004] This utility model discloses a bidirectional adjustment mechanism for a sealing machine based on a clutch mechanism, which aims to solve the technical problem that the bidirectional screw adjustment mechanism in the existing plastic bag sealing machine is prone to synchronization failure after long-term use, resulting in the position of the heat sealing blades on both sides being offset and unable to be independently fine-tuned, thus affecting the sealing quality and production efficiency.

[0005] The technical solution of this utility model is as follows: A bidirectional adjustment mechanism for an edge banding machine based on a clutch mechanism includes: a frame; a bidirectional lead screw rotatably mounted on the frame; two mounting plates through which the bidirectional lead screw passes, with one mounting plate threadedly connected to the bidirectional lead screw; a bearing including an outer ring fixedly connected to the other mounting plate and an inner ring rotatably fitted inside the outer ring; the bidirectional lead screw passing through the inner ring and threadedly connected to it; and a clutch mechanism for fixing the positions of the inner ring and the outer ring in a locked state, such that when the bidirectional lead screw is rotated, the mounting plate connected to the bearing moves synchronously; and for releasing the fixing of the inner ring and the outer ring in an unlocked state, such that when the bidirectional lead screw is rotated, the inner ring rotates relative to the outer ring, while the position of the mounting plate connected to the bearing remains unchanged.

[0006] This technical solution involves mounting the heat sealing blades on both sides of the edge banding machine onto the mounting plates on both sides of the frame. This allows for synchronous adjustment of the two heat sealing blades. Furthermore, when needed, the synchronous locking of one of the mounting plates can be released via a clutch mechanism, enabling independent adjustment of the mounting plate and heat sealing blade on that side. This effectively solves the problem in existing technologies where it is impossible to fine-tune the offset heat sealing blade individually, thus improving the flexibility and accuracy of the adjustment.

[0007] Furthermore, the clutch mechanism includes a top sleeve, which is slidably mounted on a mounting plate connected to the bearing; a locking pin is provided on the top sleeve; a first locking groove that cooperates with the locking pin is provided on the outer ring, and a plurality of second locking grooves that cooperate with the locking pin are provided on the inner ring; in the locked state, the top sleeve slides so that the locking pin is simultaneously engaged in the first locking groove and one of the second locking grooves.

[0008] More specifically, in some embodiments, a drive assembly is also included, which is disposed on a mounting plate connected to the bearing and is used to drive the top sleeve to slide; the drive assembly includes a sleeve fixed on the mounting plate, a threaded top sleeve threadedly connected to the sleeve, and a drive ring slidably disposed in the sleeve and drivenly connected to the top sleeve.

[0009] Preferably, a spring is provided between the transmission ring and the top sleeve, and the two ends of the spring are fixedly connected to the transmission ring and the top sleeve, respectively.

[0010] Furthermore, both the top sleeve and the transmission ring are provided with guide bars; the inner wall of the sleeve is provided with guide grooves that slide in cooperation with the guide bars.

[0011] Preferably, a thrust bearing is provided between the threaded top sleeve and the transmission ring, and both sides of the thrust bearing are fixedly connected to the threaded top sleeve and the transmission ring, respectively.

[0012] More specifically, one end of the bidirectional lead screw is connected to a first handwheel; and one end of the threaded top sleeve is connected to a second handwheel.

[0013] In some embodiments, the system further includes two threaded sleeves threaded to the bidirectional lead screw, one of which is fixedly inserted inside the inner ring, and the other of which is fixedly inserted on a mounting plate not connected to the bearing.

[0014] Preferably, the adjustment mechanism further includes a conveyor belt for transporting packaging bags, the conveyor belt being installed at the center of the machine frame, heat sealing strips being fixedly installed at the bottom of both mounting plates, and a pair of mating plates that cooperate with the heat sealing strips being symmetrically arranged on both sides of the conveyor belt.

[0015] Furthermore, the adjustment mechanism also includes a pair of first support plates symmetrically arranged and slidable on the frame, with a second support plate fixedly arranged at both ends of each first support plate; the two ends of the mounting plate are respectively slidably connected to the corresponding two second support plates.

Detailed Implementation

[0023] Existing technologies relying on bidirectional lead screws for synchronous adjustment have certain drawbacks. Over long-term use, the bidirectional lead screw may be affected by wear, manufacturing precision deviations, and uneven force, gradually causing its synchronous adjustment function to fail, resulting in inaccurate synchronization of the two heat-sealing blades' positions. Specifically, when one heat-sealing blade is adjusted to a preset position, the other heat-sealing blade, which should maintain symmetry, may shift in relative position. Once this shift occurs, because the bidirectional lead screw simultaneously moves both heat-sealing blades, it is difficult for the user to fine-tune the shifted blade independently without moving the already correctly positioned blade. This limitation of not being able to adjust independently directly leads to a decrease in the sealing quality of plastic bags by the heat-sealing machine, affecting production efficiency and product qualification rate.

[0024] Based on this, in order to improve the technical problem that the bidirectional screw adjustment mechanism in the plastic bag sealing machine is prone to synchronization failure after long-term use, resulting in the position of the heat sealing blades on both sides being offset and unable to be independently fine-tuned, thus affecting the sealing quality and production efficiency, the embodiments of this application provide the following solution.

[0025] The following combination Figures 1-7 This application will be described in further detail.

[0026] This embodiment discloses a bidirectional adjustment mechanism for an edge banding machine based on a clutch mechanism, including a frame 1, a bidirectional lead screw 3, two mounting plates 2, a bearing 42, and a clutch mechanism. The bidirectional lead screw 3 is a rod with left- and right-hand threads, rotatably mounted on the frame 1. Both ends of the bidirectional lead screw 3 can be connected to the frame 1 via bearings or bushings to ensure smooth rotation without axial displacement. The two mounting plates 2 are pierced by the bidirectional lead screw 3. One mounting plate 2 is threadedly connected to the bidirectional lead screw 3, while the other mounting plate 2 is connected to the bidirectional lead screw 3 via a bearing 42.

[0027] The bearing 42 includes an outer ring 422 fixedly connected to the mounting plate 2, and an inner ring 421 rotatably fitted inside the outer ring 422. The outer ring 422 can be securely fixed to the mounting plate 2 by bolts, welding, or interference fit, ensuring that it moves synchronously with the mounting plate 2. A double-acting lead screw 3 passes through the inner ring 421 and is threadedly connected to the inner ring 421. Since the inner ring 421 can rotate relative to the outer ring 422, under certain conditions, the rotation of the double-acting lead screw 3 will only drive the inner ring 421 to rotate, without causing the outer ring 422 and the mounting plate 2 to move.

[0028] The clutch mechanism is key to realizing the core function of the bidirectional adjustment mechanism. This clutch mechanism controls the relative movement between the inner ring 421 and the outer ring 422 in two states. In the locked state, the clutch mechanism fixes the positions of the inner ring 421 and the outer ring 422. At this time, since the outer ring 422 is fixedly connected to the mounting plate 2, and the inner ring 421 is threadedly connected to the bidirectional lead screw 3, when the bidirectional lead screw 3 is rotated, the inner ring 421 will drive the outer ring 422 to rotate synchronously, thereby causing the mounting plate 2 connected to the bearing 42 to move synchronously with the rotation of the bidirectional lead screw 3. This locking mechanism can take various forms, such as using pins, friction plates, gear meshing, etc., to achieve a rigid connection between the inner ring 421 and the outer ring 422. In the unlocked state, the clutch mechanism releases the fixation between the inner ring 421 and the outer ring 422. This means that the clutch mechanism will release or disengage the above-mentioned locking mechanism, allowing the inner ring 421 to rotate freely relative to the outer ring 422. At this time, when the bidirectional lead screw 3 is rotated, the thread of the bidirectional lead screw 3 will only drive the inner ring 421 to rotate, while the outer ring 422 and the mounting plate 2 connected to it will remain in the same position. This unlocking mechanism can be achieved by releasing the pin, separating the friction plate, or disengaging the gear.

[0029] In practical applications, the bidirectional adjustment mechanism of the edge-sealing machine based on the clutch mechanism in this embodiment can flexibly realize the synchronous movement and independent adjustment of the two mounting plates 2, thereby effectively solving the problem of heat sealing knife position offset in the prior art. When it is necessary to adjust the two mounting plates 2 synchronously and over a wide range, such as when changing plastic bags of different widths, the clutch mechanism is set to the locked state. In this state, the clutch mechanism firmly fixes the inner ring 421 and the outer ring 422 of the bearing 42 together, so that the inner ring 421 cannot rotate relative to the outer ring 422. Since the outer ring 422 is fixedly connected to one of the mounting plates 2, and the inner ring 421 is threadedly connected to the bidirectional lead screw 3, when the operator rotates the bidirectional lead screw 3, the rotation of the bidirectional lead screw 3 will simultaneously drive the two mounting plates 2 to move synchronously along their axial direction. Specifically, the mounting plate 2, which is directly threaded to the bidirectional lead screw 3, moves with the rotation of the bidirectional lead screw 3. Simultaneously, since the inner ring 421 and outer ring 422 are locked, the rotation of the inner ring 421 also drives the outer ring 422 and its connected mounting plate 2 to move synchronously. In this way, the two mounting plates 2 and the heat-sealing strip 73 mounted on them can be adjusted synchronously at the same speed and direction, quickly adapting to plastic bags of different sizes. When independent fine-tuning of one of the mounting plates 2 is required, for example, when it is found that the heat-sealing blades on both sides are asymmetrical due to wear or deformation, the clutch mechanism is switched to the unlocked state. In this state, the clutch mechanism releases the fixation of the inner ring 421 and outer ring 422, allowing the inner ring 421 to rotate freely relative to the outer ring 422. At this time, the mounting plate 2 connected to the bearing 42 will maintain its current position through the outer ring 422. When the operator rotates the bidirectional lead screw 3, the thread of the bidirectional lead screw 3 only drives the inner ring 421 to rotate inside the bearing 42, without moving the outer ring 422 and the mounting plate 2 connected to it. At the same time, the rotation of the bidirectional lead screw 3 will still drive the other mounting plate 2, which is threadedly connected to the bidirectional lead screw 3, to move axially. In this way, the operator can adjust the position of the offset mounting plate 2 independently without affecting the already positioned mounting plate 2 on the other side, thereby achieving precise calibration of the heat sealing knife position.

[0030] In some embodiments, the clutch mechanism includes a top sleeve 41, which is slidably mounted on a mounting plate 2 connected to a bearing 42; a locking pin 411 is provided on the top sleeve 41; a first locking groove 4221 that cooperates with the locking pin 411 is provided on the outer ring 422, and a plurality of second locking grooves 4211 that cooperate with the locking pin 411 are provided on the inner ring 421; in the locked state, the top sleeve 41 slides so that the locking pin 411 is simultaneously engaged in the first locking groove 4221 and one of the second locking grooves 4211.

[0031] The solution of this application achieves the locking and unlocking functions of the clutch mechanism through the sliding of the top sleeve 41. Specifically, when it is necessary to fix the positions of the inner ring 421 and the outer ring 422, the top sleeve 41 is driven to slide, so that the locking pin 411 provided on it simultaneously engages in the first locking groove 4221 and the second locking groove 4211, thereby fixing their positions. Conversely, when it is necessary to release the fixation, the top sleeve 41 slides in the opposite direction, so that the locking pin 411 disengages from the first locking groove 4221 and the second locking groove 4211, at which time the inner ring 421 can rotate freely relative to the outer ring 422.

[0032] In some embodiments, the drive assembly 6 includes a sleeve 62 fixed to the mounting plate 2. It also includes a threaded top sleeve 61 threadedly connected to the sleeve 62, allowing axial movement via rotation. Furthermore, the drive assembly 6 includes a transmission ring 64 slidably disposed inside the sleeve 62 and connected to the top sleeve 61, responsible for transmitting the movement of the threaded top sleeve 61 to the top sleeve 41.

[0033] When the threaded top sleeve 61 is rotated, it will move axially due to its threaded connection with the sleeve 62. This axial movement is transmitted to the top sleeve 41 through the transmission ring 64, thereby driving the top sleeve 41 to slide on the mounting plate 2. It is precisely because of this controllable sliding that the locking pin 411 can precisely engage or disengage with the locking groove of the outer ring 422 and the multiple locking grooves 4211 of the inner ring 421, thereby realizing the switching of the locking or unlocking state of the clutch mechanism.

[0034] In one specific embodiment, a spring 65 is provided between the transmission ring 64 and the top sleeve 41, and the two ends of the spring 65 are fixedly connected to the transmission ring 64 and the top sleeve 41 respectively.

[0035] With this configuration, when the transmission ring 64 approaches the bearing 42, the compressed spring 65 applies a thrust to the top sleeve 41. If at this time there is no locking groove on the inner ring 421 aligned with the locking pin 411, the locking pin 411 abuts against the side of the inner ring 421 near the top sleeve 41, thus fixing the position of the mounting plate 2 connected to the bearing 42, preventing the threaded sleeve 5 from rotating relative to the double-acting screw 3. Then, the double-acting screw 3 is slightly rotated, causing the threaded sleeve 5 to rotate, so that a second locking groove 4211 on the inner ring 421 is aligned with the locking pin 411. The spring 65 pushes the locking pin 411 into the first locking groove 4221 and the second locking groove 4211, fixing the relative position of the inner ring 421 and the outer ring 422. When the transmission ring 64 moves away from the bearing 42, the spring 65 can pull the top sleeve 41 away from the bearing 42, unlocking the clutch mechanism.

[0036] In some embodiments, both the top sleeve 41 and the transmission ring 64 are provided with guide bars 412; the inner wall of the sleeve 62 is provided with a guide groove 621 that slides with the guide bars 412.

[0037] By providing guide bars 412 on the top sleeve 41 and the transmission ring 64, and by creating a guide groove 621 on the inner wall of the sleeve 62, the top sleeve 41 and the transmission ring 64 can move precisely along the direction of the guide groove 621 when sliding within the sleeve 62. This prevents the top sleeve 41 and the transmission ring 64 from deflecting or getting stuck during sliding, ensuring the stability and reliability of the drive assembly 6. Simultaneously, the cooperation between the guide bars 412 and the guide groove 621 prevents the transmission ring 64 from rotating relative to the top sleeve 41 within the sleeve 62, ensuring that the locking pin 411 is always aligned with the first locking groove 4221, thereby guaranteeing the locking effect of the clutch mechanism.

[0038] In some embodiments, a thrust bearing 63 is provided between the threaded top sleeve 61 and the transmission ring 64, and the two sides of the thrust bearing 63 are fixedly connected to the threaded top sleeve 61 and the transmission ring 64, respectively.

[0039] The thrust bearing 63 can be used to transmit the thrust and pull forces applied by the threaded top sleeve 61 to the drive ring 64, so that the drive ring 64 can move synchronously with the threaded top sleeve 61. The thrust bearing 63 can also allow the threaded top sleeve 61 to rotate relative to the drive ring 64, ensuring the normal operation of the drive assembly 6.

[0040] In some embodiments, one end of the bidirectional lead screw 3 is connected to a first handwheel 31; and one end of the threaded top sleeve 61 is connected to a second handwheel 611.

[0041] The position of the bidirectional lead screw 3 can be adjusted directly and quickly via the first handwheel 31, thereby adjusting the distance between the two mounting plates 2 and achieving coarse adjustment; the state switching of the clutch mechanism can be controlled more conveniently via the second handwheel 611, without the need for other tools or complicated steps, simplifying the operation process and improving adjustment efficiency.

[0042] In some embodiments, the adjusting mechanism further includes two threaded sleeves 5 threadedly connected to the bidirectional lead screw 3, one threaded sleeve 5 being fixedly inserted inside the inner ring 421, and the other threaded sleeve 5 being fixedly inserted on the mounting plate 2 not connected to the bearing 42.

[0043] By adding a threaded sleeve 5, the direct threaded connection between the bidirectional lead screw 3, the mounting plate 2, and the bearing 42 is transformed into an indirect connection, thereby dispersing the stress at the threaded connection, reducing the wear rate, and improving the stability and reliability of the connection. At the same time, the replaceability of the threaded sleeve 5 significantly reduces maintenance costs and extends the overall service life of the equipment.

[0044] The adjustment mechanism also includes a conveyor belt 7 for transporting packaging bags. The conveyor belt 7 is installed at the center of the machine frame. Heat sealing strips 73 are fixedly installed at the bottom of both mounting plates 2. A pair of mating plates 74 that cooperate with the heat sealing strips 73 are symmetrically arranged on both sides of the conveyor belt 7. The heat-sealing strip 73 is a component used for heat-sealing packaging materials. The heat-sealing strip 73 can be fixed to the bottom of the mounting plate 2 by means of screws, rivets, or welding. The conveyor belt 7 is used for automatically transporting the plastic bags that need to be heat-sealed. The heat-sealing strip 73 cooperates with the mating plate 74 to heat-seal the opening of the plastic bag.

[0045] In some embodiments, the adjustment mechanism further includes a pair of first support plates 71 symmetrically arranged and slidable on the frame 1, with a second support plate 72 fixedly arranged at both ends of the first support plates 71; the two ends of the mounting plate 2 are respectively slidably connected to the corresponding two second support plates 72.

[0046] When the mounting plate 2 is driven to move horizontally by the bidirectional lead screw 3, the mounting plate 2 can drive the second support plates 72 connected to its two ends to move, thereby causing the first support plate 71 to slide on the frame 1, realizing the adjustment of the horizontal position of the heat-sealing strip 73. The device can synchronously control the mounting plates 2 on both sides to slide up and down on the second support plates 72 in the vertical direction through some common power sources, so that the heat-sealing strip 73 and the mating plate 74 seal the plastic bag. The power source can be an electric push cylinder, a hydraulic cylinder, a power mechanism composed of a servo motor and transmission components, etc.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
