Description

Technical Field

[0001] This utility model relates to the field of bottle-making equipment, and in particular to a device for detecting and correcting the horizontal level of the bottle-making machine's jaw clamps. Background Technology

[0002] Bottle making machines are specialized equipment used to produce various types of bottles, widely used in the food and beverage, pharmaceutical, and daily chemical industries. Based on the production materials and processes, they can be divided into glass bottle making machines and plastic bottle making machines. Glass bottle making machines melt raw materials such as quartz sand and soda ash into liquid glass at high temperatures, then use molds to blow or press the glass to form the bottle body; they are commonly used for producing wine bottles and infusion bottles. Plastic bottle making machines use plastic granules such as PET and PE as raw materials, which are heated and melted, then extruded or injected to form preforms, followed by blow molding; they are suitable for manufacturing mineral water bottles, cosmetic bottles, etc. Their key components include a raw material handling system (such as a glass furnace and plastic screw extruder), a forming system (molds and blowing / pressing mechanisms), a transmission and control system (PLC or computer control), and a cooling and demolding system. These parts work together to ensure accurate raw material forming and efficient output. Bottle-making machines are characterized by high automation, high production efficiency, stable product quality, and strong customizability. They not only automate the entire process from raw materials to finished products, significantly reducing manual intervention, but also produce bottles of different shapes, sizes, and functions by adjusting molds and parameters to meet diverse market demands. Simultaneously, relying on precision temperature and pressure control technology ensures uniform bottle wall thickness and accurate dimensions, improving production efficiency while reducing defect rates. They are an indispensable key piece of equipment in the modern packaging industry. During processing, vises are used to clamp the formed bottle neck. Depending on the type of bottle-making machine (e.g., two-drop, three-drop, four-drop), the vises are correspondingly available in two-jaw, three-jaw, or four-jaw configurations. In actual production, the horizontal position of the vises is crucial for accurate clamping of the bottle neck and subsequent forming.

[0003] However, in existing technologies, when the jaw clamp is not in a horizontal position, it usually requires manual adjustment by the operator. This manual calibration method is inefficient, time-consuming, and labor-intensive, affecting production efficiency. To address these issues, existing technologies urgently need improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a horizontal detection and correction device for bottle-making machine mouth clamps.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a bottle-making machine mouth clamp horizontal detection and correction device, comprising:

[0006] Mounting base, testing mechanism, and calibration structure;

[0007] Two electric slide rails are symmetrically mounted on the front of the mounting base, and sliders are slidably connected to both electric slide rails; left and right jaws are respectively mounted on the two sliders.

[0008] The testing mechanism includes a connecting rod and a laser displacement sensor mounted on the connecting rod.

[0009] The calibration mechanism includes a connecting seat, a second rotary motor mounted on the connecting seat, a drive sprocket, a chain, a driven sprocket, a threaded rod, and a top block. The output end of the second rotary motor is rotatably connected to the drive sprocket. The drive sprocket is connected to the driven sprocket via a chain. The top end of the threaded rod is rotatably connected to the top block via a rotating shaft. The threaded rod is fixedly connected to the top end of the driven sprocket.

[0010] Preferably, the left and right jaws are mounted on two sliders respectively via bolt threads.

[0011] Preferably, the connecting rod is fixedly installed on one side of the mounting base, and two laser displacement sensors are symmetrically installed on the connecting rod.

[0012] Preferably, mounting blocks are fixedly installed on the non-adjacent sides of the left and right jaws, and openings are made on both mounting blocks. The positions of the mounting blocks correspond to the adjacent laser displacement sensors.

[0013] Preferably, the connecting seat is mounted on the slider.

[0014] Preferably, the calibration mechanism further includes a support base and a slide groove. The support base is disposed on the connecting seat, and the top block is threadedly connected to the threaded rod and slidably connected to the slide groove.

[0015] Preferably, a first rotary motor is provided on one side of the mounting base, and the first rotary motor is connected to the mounting base through a reducer.

[0016] Preferably, the left and right jaws are the same size.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model discloses a bottle-making machine clamp horizontal detection and correction device. By setting up a detection mechanism, a laser displacement sensor detects the position of the opening on the mounting block of the clamp to determine whether the clamp is horizontal. When the clamp is detected to be horizontal, a correction mechanism set on the slider uses a second rotary motor to drive a chain transmission mechanism and a threaded rod to rotate, causing the top block to move and lift the clamp, thus automatically correcting the horizontal position of the clamp. This technical solution integrates detection and correction, realizing automated detection and correction of the clamp's horizontal position. It solves the problem of low efficiency in manual calibration in existing technologies, improves calibration efficiency, reduces labor costs, and represents a significant technological advancement.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] In the field of bottle-making equipment technology, especially in the production process of row-type bottle-making machines, after the bottle neck is formed, it needs to be clamped by a clamping device and flipped to the mold side for subsequent blowing. As bottle-making machines develop towards multi-drop material production, the types of clamping devices have also increased accordingly. In existing technologies, the horizontal position of the clamping device is crucial to the accuracy of bottle neck clamping. However, when the clamping device tilts, manual calibration is usually required, which is inefficient and cannot meet the needs of modern production. To overcome the problem of low efficiency in manual calibration in existing technologies, this invention proposes a bottle-making machine clamping device for horizontal detection and correction. This device, through an integrated detection and correction mechanism, achieves automated detection and correction of the horizontal position of the clamping device, significantly improving calibration efficiency.

[0025] like Figures 1 to 2 The bottle-making machine mouth clamp horizontal detection and correction device shown includes:

[0026] Mounting base 1, detection mechanism and calibration structure;

[0027] Two electric slide rails 2 are symmetrically mounted on the front of the mounting base 1. Slider 3 is slidably connected to each of the two electric slide rails 2. A left jaw 18 and a right jaw 19 are respectively mounted on the two sliders 3.

[0028] The testing mechanism includes a connecting rod 7 and a laser displacement sensor 6 mounted on the connecting rod 7.

[0029] The calibration mechanism includes a connecting seat 8, a second rotary motor 9 mounted on the connecting seat 8, a drive sprocket 10, a chain 11, a driven sprocket 12, a threaded rod 13, and a top block 14. The output end of the second rotary motor 9 is rotatably connected to the drive sprocket 10. The drive sprocket 10 is connected to the driven sprocket 12 via the chain 11. The top end of the threaded rod 13 is rotatably connected to the top block 14 via a rotating shaft. The threaded rod 13 is fixedly connected to the top end of the driven sprocket 12.

[0030] In practice, the detection mechanism emits a laser beam through the laser displacement sensor 6 and receives the signal reflected from the opening 21. The depth or position of the opening 21 is determined based on the change in the signal, thereby indirectly reflecting the vertical height of the jaws. The correction mechanism drives the drive sprocket 10, chain 11 and driven sprocket 12 to rotate through the second rotary motor 9, and transmits the rotational power to the threaded rod 13. The rotation of the threaded rod 13 converts the rotational motion into the linear motion of the top block 14 through the threaded pair, thereby realizing the lifting or lowering of the left jaw 18 and the right jaw 19 respectively.

[0031] In one embodiment of this utility model, the left jaw 18 and the right jaw 19 are respectively mounted on the two sliders 3 by bolts 4.

[0032] In practice, the left jaw 18 and the right jaw 19 are respectively mounted on the two sliders 3 by bolts 4. The bolts 4 pass through the left jaw 18 and the right jaw 19 and are threaded onto the sliders 3, thereby firmly fixing the left jaw 18 and the right jaw 19 to the sliders 3. This connection method has a simple structure, high reliability, and good disassembly. By loosening or tightening the bolts 4, the left jaw 18 and the right jaw 19 can be easily installed, disassembled, or replaced. Therefore, the use of threaded connection to install the left jaw 18 and the right jaw 19 on the sliders 3 provides convenience for the assembly, maintenance, and component replacement of the device, and improves the practicality and maintainability of the device.

[0033] In one embodiment of this utility model, the connecting rod 7 is fixedly installed on one side of the mounting base 1, and two laser displacement sensors 6 are symmetrically installed on the connecting rod 7.

[0034] In practice, the two laser displacement sensors 6 are mirror-symmetrical in position relative to the center line of the mounting base 1, enabling them to detect the left jaw 18 and the right jaw 19 respectively. The laser displacement sensor 6 is a sensor capable of accurately measuring distance; it determines the distance or position of the target object by emitting a laser beam and analyzing the reflected signal. By symmetrically mounting the two laser displacement sensors 6 on the connecting rod 7, they can detect the left jaw 18 and the right jaw 19 at the same angle and distance relative to their respective target points. Therefore, by comparing the data acquired by the two laser displacement sensors 6, it is possible to intuitively and accurately determine whether there is a height difference between the left jaw 18 and the right jaw 19, i.e., whether the jaw clamps are in a horizontal position. This symmetrical detection method simplifies data processing and judgment logic, effectively improving the accuracy and efficiency of detection.

[0035] As one embodiment of this utility model, mounting blocks 20 are fixedly installed on the non-adjacent sides of the left jaw 18 and the right jaw 19. Openings 21 are provided on both mounting blocks 20, and the positions of the mounting blocks 20 correspond to the adjacent laser displacement sensors 6.

[0036] In practical implementation, the mounting block 20 is positioned to correspond to the adjacent laser displacement sensor 6, allowing the laser beam emitted by the laser displacement sensor 6 to illuminate the area of ​​the opening 21. The mounting block 20 can be made of metal, plastic, or other suitable materials. The opening 21 can be a blind hole or a through hole, and its shape, size, and depth can be designed according to the detection principle and accuracy requirements of the laser displacement sensor 6. For example, if a depth-based laser displacement sensor 6 is used, the opening 21 can be designed as a blind hole with a specific depth. The vertical position of the jaws is determined by measuring the distance from the laser beam to the bottom of the hole. Therefore, the design of the opening 21 allows the laser displacement sensor 6 to focus on a specific area for measurement, avoiding interference from other features on the jaws surface and improving the accuracy and reliability of the detection.

[0037] In one embodiment of this utility model, the connecting seat 8 is mounted on the slider 3.

[0038] In practice, the connecting seat 8 serves as a connector between the correction mechanism and the slider 3, which can securely fix the correction mechanism on the slider 3. This installation method allows the correction mechanism to directly act on the side jaws on which it is installed, and to adjust its vertical lifting or lowering. Therefore, it avoids transmission errors or structural deformation that may occur due to separation of the installation position, and improves the accuracy and response speed of the correction.

[0039] As one embodiment of the present invention, the calibration mechanism further includes a support base 15 and a slide groove 16. The support base 15 is disposed on the connecting base 8, and the top block 14 is threadedly connected to the threaded rod 13 and slidably connected to the slide groove 16.

[0040] In practice, the threaded rod 13 passes through the support base 15, and the top block 14 is threaded onto the threaded rod 13. The external shape of the top block 14 matches the internal shape of the slide groove 16, so that when the threaded rod 13 rotates, the top block 14 can only move linearly along the guide direction of the slide groove 16, and cannot rotate with the threaded rod 13. The slide groove 16 is designed as a straight line to ensure that the top block 14 moves vertically, thereby realizing the lifting or lowering of the jaw clamps.

[0041] As one embodiment of this utility model, a first rotary motor 5 is provided on one side of the mounting base 1, and the first rotary motor 5 is connected to the mounting base 1 through a reducer 17.

[0042] In practical implementation, the first rotary motor 5 can be an AC motor, DC motor, or stepper motor, the selection of which depends on the required rotational speed, torque, and control precision. The reducer 17 can be a gear reducer, worm gear reducer, or other type of reduction mechanism. Thus, by setting the first rotary motor 5 and the reducer 17 and connecting them to the connecting seat 8, the entire bottle-making machine's jaw clamp horizontal detection and correction device can achieve a rotational function. Although this rotational function is not directly used for the horizontal correction of the jaw clamp, it is a necessary function for the bottle-making machine's jaw clamp device to perform flipping and shaping after clamping.

[0043] In one embodiment of this utility model, the left jaw 18 and the right jaw 19 are of the same size.

[0044] In practice, the consistent size design helps ensure that the left jaw 18 and the right jaw 19 can provide symmetrical clamping force and support when clamping the bottle mouth, thereby improving the stability and reliability of clamping.

[0045] Working principle of this utility model:

[0046] In use, the bottle-making machine's clamp horizontal detection and correction device is installed at the corresponding position on the bottle-making machine. When clamping a droplet, the sliders 3 on the two electric slide rails 2 can move the left clamp 18 and the right clamp 19 respectively, changing the distance between them to clamp droplets of different sizes. To detect the horizontal position of the clamps, a detection mechanism is used. Laser displacement sensors 6 are installed on the connecting rods 7 on both sides of the mounting base 1. These two laser displacement sensors 6 correspond to the openings 21 on the mounting blocks 20 of the left clamp 18 and the right clamp 19, respectively. The laser displacement sensors 6 emit laser light and receive the reflected light to detect the depth of the opening 21. If the depths of the opening 21 detected by the two laser displacement sensors 6 are different, it indicates that the left clamp 18 and the right clamp 19 are not in a horizontal position. At this time, the correction mechanism is activated. The connecting seat 8 mounted on the slider 3 drives the drive sprocket 10 to rotate via the second rotary motor 9 on the connecting seat 8. This drives the driven sprocket 12 via the chain 11, which in turn drives the threaded rod 13 to rotate. The rotation of the threaded rod 13, through the threaded pair, causes the top block 14 to move along the slide groove 16 of the support seat 15. If the jaw clamp tilts, for example, one side is lower, the correction mechanism on the slider 3 of that side is controlled to move the top block 14 upwards, lifting the jaw clamp to the corresponding position on that side until the height of the jaw clamp on that side matches the height of the other side, i.e., the jaw clamp returns to a horizontal position. The entire detection and correction process can be automatically completed by the control system. Furthermore, the device may also include a first rotary motor 5, which is connected to the mounting base 1 via a reducer 17. This first rotary motor 5 drives the entire mounting base 1 to rotate, causing the clamped droplet to flip, so that the bottle mouth faces upwards for final blow molding. During this operation, mounting base 1 provides a stable mounting platform, electric slide rail 2 and slider 3 provide lateral adjustment capability for the jaws, and left jaws 18 and right jaws 19 directly perform clamping functions. The connecting rod 7 and laser displacement sensor 6 in the detection mechanism are responsible for acquiring the vertical position information of the jaws, with mounting block 20 and opening 21 serving as detection targets. In the calibration mechanism, connecting base 8 is the mounting base, the second rotary motor 9 provides power, and the drive sprocket 10, chain 11, and driven sprocket 12 form the transmission chain. Threaded rod 13 and top block 14 convert rotational motion into linear lifting motion, and support base 15 and slide groove 16 provide guidance for top block 14. Through the coordinated work of these components, automated and precise detection and calibration of the horizontal position of the bottle-making machine jaws are achieved.
