Technical Field
[0001] This utility model belongs to the technical field of blow molding equipment, and in particular relates to a feeding device for a bottle unscrambler. Background Technology
[0002] Injection blow molding is a method for manufacturing hollow plastic products. It involves first injecting molten plastic into an injection mold using an injection molding machine to form a preform, which is then blow-molded into its final shape. Injection blow molding is characterized by dimensional precision, no need for secondary processing, stable part weight, no scrap or flash, and a good appearance. It is commonly used in the processing of polystyrene bottles, polypropylene copolymers, and polyethylene bottles.
[0003] In blow molding production lines, the efficient conveying and precise sorting of preforms are crucial, typically accomplished collaboratively by a feeding device and a preform sorting device. The feeding device handles the transfer of preforms from the storage area to the sorting device, while the sorting device orients and arranges disordered preforms to ensure their orderly entry into subsequent blow molding processes. Existing traditional feeding devices generally employ a feeding support structure, with a circulating conveyor belt installed on the inclined surface of the support. Baffles are evenly spaced along the conveyor belt, and a hopper is located on the outer side of the bottom of the support. In actual operation, preforms in the hopper fall under their own weight into the gaps between adjacent baffles on the conveyor belt, and are then lifted to a higher position by the conveyor belt.
[0004] However, in actual operation, certain defects were found in the aforementioned feeding device: when the hopper capacity needs to be increased to accommodate more preforms, the increased stacking height of the preforms leads to a significant increase in the lateral extrusion force generated by their own weight. This not only causes mutual extrusion and deformation between preforms, affecting product consistency and quality stability, but also applies excessive mechanical load to the conveyor belt, causing it to deviate, twist, or even break, ultimately leading to equipment downtime and production interruption. Simultaneously, the large hopper design obstructs the preform discharge path, easily causing blockages, reducing conveying efficiency, and making manual material dumping difficult. Workers need to expend considerable physical strength and time to add material, significantly increasing labor intensity and affecting the continuity of the production line. These defects severely restrict the reliability and operating efficiency of the blow molding production line. Therefore, it is urgent to design a feeding device for bottle unscramblers to solve these problems. Summary of the Invention
[0005] This invention provides a feeding device for a bottle unscrambler with a reasonable structural design to solve the technical problems existing in the prior art.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A feeding device for a bottle unscrambler includes a second support, on which a feeding transmission line and a buffer bin structure are installed.

It also includes a first support arranged beside the second support, on which an outlet transmission line is installed. The material conveying line is set perpendicular to the conveying direction of the second support. A guide plate structure corresponding to its conveying surface is installed on the discharge conveying line. An inclined conveying assembly is set between the discharge conveying line and the feeding conveying line. The inlet end of the inclined conveying assembly is located below the outlet end of the feeding conveying line, and the outlet end of the inclined conveying assembly is located above the inlet of the guide plate structure. The clamping mechanism includes a mounting base structure fixed to the tilting hopper. At least two sets of telescopic guide rods are slidably connected to the mounting base structure via linear bearings. The linear bearings pass through through holes opened in the tilting hopper. A clamping block seat plate located in the inner cavity of the tilting hopper is installed at the outer end of the at least two sets of telescopic guide rods. A clamping block is installed on the clamping block seat plate. The mechanism also includes clamping springs sleeved on each telescopic guide rod.

[0016] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided in detail: Please see Figure 1 and Figure 2 The feeding device for the bottle unscrambler of this utility model includes a second support 10. A feeding transmission line 9 and a buffer bin structure 5 are installed on the second support 10. The buffer bin structure 5 is located above the transmission surface of the feeding transmission line 9 and is fitted with it with a gap. The discharge port of the buffer bin structure 5 and the discharge end of the feeding transmission line 9 are arranged vertically and vertically respectively. A tilting hopper 7 is pivotally connected to the top of the second support 10, and a pouring cylinder 8 is pivotally connected between the bottom of the tilting hopper 7 and the second support 10. The tilting hopper 7 is shaped like a sieve, and two symmetrically arranged clamping mechanisms 6 are installed on the tilting hopper 7 to clamp the material box placed in the tilting hopper 7. It also includes a first support 1 set on the side of the second support 10, a discharge transmission line 2 installed on the first support 1, the transmission direction of the discharge transmission line 2 is set perpendicular to the transmission direction of the second support 10, and a guide plate structure 3 corresponding to its transmission surface is installed on the discharge transmission line 2. An inclined conveyor assembly 4 is provided between the discharge conveyor line 2 and the feeding conveyor line 9. The inlet of the inclined conveyor assembly 4 is located below the discharge end of the feeding conveyor line 9, and the discharge end of the inclined conveyor assembly 4 is located above the inlet of the guide plate structure 3. like Figure 3 As shown, the clamping mechanism 6 includes a mounting base structure fixedly attached to the tilting hopper 7. At least two sets of telescopic guide rods 6-2 are slidably connected to the mounting base structure via linear bearings, with the linear bearings passing through through holes opened in the tilting hopper 7. A clamping block seat plate 6-3 located in the inner cavity of the tilting hopper 7 is installed at the outer end of the at least two sets of telescopic guide rods 6-2, and a clamping block 6-4 is installed on the clamping block seat plate 6-3. It also includes clamping springs 6-1 sleeved on each telescopic guide rod 6-2.
[0017] The above-described setup, through the coordination of the tilting hopper 7 and the buffer bin structure 5, avoids the excessive compressive force caused by the long-term accumulation of preforms due to their own weight, a problem common in traditional large hopper designs. Simultaneously, the inclined conveyor assembly 4 and the guide plate structure 3 optimize the preform transport path, improving discharge efficiency and ease of operation. This design not only solves the problems of preforms squeezing each other and conveyor belt deformation but also simplifies the operator's workflow, thereby enhancing overall work efficiency.
[0018] like Figure 3 As shown, the mounting structure includes two sets of clamping mounting seats 6-5 fixedly connected to the pouring hopper 7. Several mounting connecting rods 6-7 are fixedly connected between the two sets of clamping mounting seats 6-5 to connect them into one unit. Two sets of linear bearings are installed on each clamping mounting seat 6-5 and two sets of telescopic guide rods 6-2 are slidably connected to them through the linear bearings.
[0019] In detail, the above-mentioned setup, by incorporating two sets of clamping mounting seats 6-5 on the pouring hopper 7, effectively disperses the lateral extrusion force from the preforms within the hopper, avoiding localized deformation caused by single-point stress. By setting several mounting rods 6-7 between the two sets of clamping mounting seats 6-5, a stable frame structure is formed, significantly improving the overall torsional resistance. The linear bearings mounted on each clamping mounting seat 6-5 work in conjunction with the telescopic guide rod 6-2 to ensure the precision and stability of the clamping action. This structural design not only solves the problem of mounting seat distortion caused by the large preform extrusion force but also ensures that the clamping mechanism can stably fix the hopper, thereby ensuring the reliability and continuity of the pouring process. Simultaneously, this structure forms an organic whole with the pouring hopper 7, further enhancing the overall stability of the device.
[0020] The above settings effectively solve the problem of mounting seat distortion or displacement caused by high preform extrusion pressure, ensuring that the clamping mechanism can stably fix the material box and improving the accuracy and reliability of the feeding process.
[0021] like Figure 3 As shown, the inner ends of the two telescopic guide rods 6-2 that are slidably connected on the same clamping mounting base 6-5 are each equipped with a clamping block seat plate 6-3, and the clamping block 6-4 is installed between the two clamping block seat plates 6-3. The clamping block 6-4 is made of rubber.
[0022] Specifically, the clamping block base plate 6-3 refers to the support structure used to install and fix the clamping block 6-4. It can be made of metal sheet through machining, and its purpose is to provide a stable mounting base for the clamping block 6-4, ensuring that the clamping block 6-4 maintains a stable position during clamping operations. The clamping block 6-4 is the functional component that directly contacts the material box and applies clamping force. It can be made of elastic polymer materials such as silicone or polyurethane, and its purpose is to utilize the elastic deformation characteristics of the material to absorb instantaneous impact energy and buffer the contact force between the preform and the clamping block.
[0023] In detail, two telescopic guide rods 6-2 mounted on the same clamping mounting base 6-5 achieve the mobility of the clamping block base plate 6-3 through a sliding connection. This structural design ensures that the clamping block 6-4 can maintain dynamic balance during clamping. The clamping block 6-4 is installed between the two clamping block base plates 6-3. Through the constraint of the clamping block base plates 6-3 on both sides, a symmetrical distribution of clamping force is achieved, effectively preventing the clamping block 6-4 from rotating or sliding under force. The rubber material of the clamping block 6-4 not only avoids scratches or indentations that may be caused by hard materials, but its moderate coefficient of friction also enhances the reliability of clamping and prevents the material box from slipping during transmission. This design cleverly solves the problem of damage to the preform due to hard impact during clamping, while ensuring that the material box is clamped stably and reducing the shaking and impact caused by uneven clamping of the internal preform.
[0024] Through the above settings, the clamping mechanism 6 effectively solves the problem of damage to the preform during the clamping process by optimizing the material selection and installation structure design of the clamping blocks 6-4, thereby improving the integrity of the product and the conveying efficiency.
[0025] The outer ends of the two telescopic guide rods 6-2 that are slidably connected on the same clamping mounting base 6-5 are each equipped with a guide rod connecting plate 6-6.
[0026] In practical applications, the guide rod connecting plate 6-6 refers to a mechanical structure used to connect two telescopic guide rods 6-2. It can be made of rigid sheet metal and fixed to the outer ends of the telescopic guide rods 6-2 through welding, bolting, or other methods. Its purpose is to constrain the degrees of freedom of the telescopic guide rods 6-2 through mechanical linkage, ensuring that the two telescopic guide rods 6-2 move synchronously during clamping, thereby improving clamping stability. Specifically, in the aforementioned bottle unscrambler feeding device, when the clamping spring applies force, the guide rod connecting plate 6-6 forces the two telescopic guide rods 6-2 to extend and retract synchronously, avoiding the problem of tilting of the clamping block seat plate caused by independent movement. This design allows the clamping block to evenly distribute the clamping force, preventing the material box from shifting or loosening during clamping. Furthermore, since the guide rod connecting plate 6-6 works in conjunction with the linear bearing on the clamping mounting base 6-5, a complete mechanical linkage system is formed, effectively solving the problem of unstable material box clamping caused by asynchronous guide rod movement and improving the reliability of the feeding process. This simple yet crucial structural improvement not only optimized the performance of the clamping mechanism but also ensured the operational stability of the entire feeding device.
[0027] like Figure 2 As shown, the buffer bin structure 5 includes a back plate 5-2 that is mounted on the second support 10 and is adjacent to the tilting hopper 7. A baffle plate 5-1 is integrally formed on the back plate 5-2 and is disposed opposite to it. The back plate 5-2 and the two baffle plates 5-1 are all inclined and the inclination direction is from top to bottom towards the middle of the transmission surface of the feeding transmission line 9.
[0028] In practical applications, the back baffle 5-2 refers to a vertical or near-vertical plate-like structure used to constrain the movement path of the preform. It can be made of materials with a certain degree of rigidity, such as metal sheets or high-strength plastic sheets, and its purpose is to prevent the preform from scattering or accumulating in non-working areas. The inclined baffle 5-1 can be understood as an inclined guide plate extending from both sides of the back baffle 5-2. It can be connected to the back baffle 5-2 through integral injection molding, welding, or fastener fixation, etc., to form a naturally converging guide channel and prevent the preform from spreading to both sides of the transmission surface.
[0029] Specifically, this solution involves installing a back plate 5-2 adjacent to the pouring hopper 7 on the second support 10. This ensures that preforms falling from the pouring hopper 7 are immediately confined within a preset path, effectively preventing them from scattering or accumulating in non-working areas. Two integrally formed inclined baffles 5-1 on the back plate 5-2 are positioned opposite each other, forming a naturally converging guide channel. The integrated structure enhances lateral constraint, ensuring stable movement of the preforms along the centerline. Both the back plate 5-2 and the inclined baffles 5-1 are inclined, with their inclination direction from top to bottom towards the center of the conveyor surface of the feeding conveyor line 9. This design utilizes gravity to allow the preforms to smoothly slide along the inclined surface to the center of the conveyor belt, reducing contact stress between preforms and automatically aligning them under gravity, facilitating precise gripping by the conveyor belt. Through these features, the risks of jamming and conveyor deviation caused by uneven accumulation are fundamentally eliminated. Furthermore, this design effectively complements the pouring hopper 7, improving the overall efficiency and stability of the device.
[0030] like Figure 4 As shown, the inclined conveyor assembly 4 includes an inclined conveyor belt 4-1 installed between the first support 1 and the second support 10, and two oppositely arranged feeding baffles 4-2 installed on the side wall of the inclined conveyor belt 4-1; the inclined conveyor belt 4-1 includes an inclined transmission frame installed between the first support 1 and the second support 10, two transmission rollers rotatably connected to the transmission frame and distributed vertically, a transmission belt drivingly connected between the two transmission rollers, and a plurality of evenly distributed baffles provided on the transmission belt; it also includes a drive motor installed on the transmission frame for driving the two transmission rollers to rotate.
[0031] Specifically, the inclined conveyor belt 4-1 refers to a device capable of continuous material transport on an inclined surface. It can be implemented using a belt, chain, or roller structure, and its purpose is to provide a stable transport path for preforms from low to high. The feeding baffle 4-2 can be understood as a component used to limit the lateral movement of the material. It can be fixed to the side wall of the inclined conveyor belt 4-1 by welding, bolting, or integral molding, and its purpose is to prevent preforms from slipping out during transport. In practical applications, the transmission frame refers to the basic framework supporting the entire inclined conveyor belt 4-1. It can be formed by welding or casting metal profiles, and its purpose is to ensure the stability of the overall structure. The transmission roller is a key component for realizing the movement of the transmission belt. It can be connected to the transmission frame through bearing seats and power transmission is achieved through keyway engagement. The baffle bar refers to a raised structure set on the transmission belt, which can be made of rubber or metal, and its purpose is to prevent preforms from slipping due to gravity.
[0032] In detail, the aforementioned inclined conveyor assembly 4 achieves stable preform transport through the organic cooperation of its various components. The inclined conveyor belt 4-1 forms a stable inclined transport surface between the first support 1 and the second support 10, ensuring that the preform can be smoothly lifted from the discharge end of the feeding conveyor line 9 to the inlet of the discharge conveyor line 2. Two feeding baffles 4-2 are symmetrically arranged on both sides of the inclined conveyor belt 4-1, effectively limiting the lateral movement range of the preform and preventing it from slipping out of the transport path due to shaking or external forces. The conveyor frame, as the basic support structure, ensures the precise positional relationship of the two conveyor rollers, thereby guaranteeing the smooth operation of the conveyor belt. Evenly distributed baffles work in conjunction with the conveyor belt to form an intermittent blocking structure, effectively overcoming the tendency of the preform to slide down the inclined surface. The drive motor drives the conveyor rollers to rotate through the transmission system, providing reliable power for the entire transport process.
[0033] The above setup not only solves the problem of bottle preforms slipping and accumulating during inclined conveying, but also significantly improves conveying efficiency and stability. Especially when used in conjunction with feeding conveyor line 9 and discharging conveyor line 2, it forms a complete bottle preform conveying system, achieving a smooth transition from horizontal conveying to inclined climbing and back to horizontal conveying.
[0034] like Figure 4 As shown, the guide plate structure 3 includes two symmetrically arranged discharge guide plates 3-2 fixed to the side wall of the discharge transmission line 2 and located below the discharge end of the inclined transmission assembly 4. The upper end of each discharge guide plate 3-2 is bent outward to form an flared shape. It also includes two discharge low baffles 3-1 fixed to the side wall of the discharge transmission line 2 and arranged opposite to the two discharge guide plates 3-2. The upper end of each discharge low baffle 3-1 is bent inward to form a constricted shape.
[0035] Specifically, the discharge guide plate 3-2 is a guide component used to smoothly guide the preform from the ramp conveyor assembly 4 to the discharge conveyor line 2. It can be made by stamping or injection molding of metal sheet. Its purpose is to expand the inlet receiving area through the flared design, thereby effectively avoiding impact jamming of the preform due to initial position deviation or speed fluctuation. The discharge low baffle 3-1 can be understood as a limiting component used to constrain the lateral movement range of the preform. It can be made of elastic material or have a buffer layer. Its purpose is to gradually narrow the movement range of the preform through the constricted design, preventing it from lateral deviation or derailment from the track during transmission due to inertia or external force interference.
[0036] In detail, this technical solution effectively solves the stability problem of preforms during the transfer transition stage by specifically designing the geometry of the guide plate structure 3. The flared design of the discharge guide plate 3-2 expands the inlet receiving area according to the dynamic falling trajectory of the preforms at the discharge end of the inclined conveyor assembly 4, allowing the preforms to naturally and smoothly slide in following the flared guide after leaving the inclined conveyor assembly 4. At the same time, the constricted design of the discharge low baffle 3-1 forms a progressive lateral constraint after the preforms enter the conveyor line, based on the preform arrangement requirements during the operation of the discharge conveyor line 2. The constricted structure gradually narrows the range of motion of the preforms, ensuring that the preforms enter the subsequent processes in a stable posture, thereby maintaining the continuity and reliability of the transfer process. In addition, the combined use of this guide plate structure 3 with the inclined conveyor assembly 4 and the discharge conveyor line 2 can significantly improve the efficiency and stability of preform transfer, reflecting the ingenious concept of the overall solution.
[0037] Working principle: During operation, the preforms are guided to the feeding conveyor line 9 via the buffer chamber structure 5, avoiding the squeezing pressure problem caused by the preforms' own weight accumulation in traditional hoppers. Furthermore, a tilting hopper 7 is pivotally connected to the top of the second support 10. The tilting hopper 7 is shaped like a sieve, and its bottom is pivotally connected to the second support 10 via a pouring cylinder 8. When the operator places the box containing the preforms into the tilting hopper 7, two symmetrically arranged clamping mechanisms 6 clamp and fix the box. Subsequently, the pouring cylinder 8 drives the tilting hopper 7 to complete the tilting action, allowing the preforms to fall orderly into the buffer chamber structure 5.
[0038] The clamping mechanism 6 operates as follows: A mounting base is fixed to the tilting hopper 7. At least two sets of telescopic guide rods 6-2 are slidably connected via linear bearings. The linear bearings pass through through holes in the tilting hopper 7. A clamping block seat plate 6-3 is mounted on the outer end of each telescopic guide rod 6-2, and clamping blocks 6-4 are mounted on the clamping block seat plate 6-3 for clamping the material box. Each telescopic guide rod 6-2 is fitted with a clamping spring 6-1. The elastic force provided by the clamping springs 6-1 ensures that the clamping mechanism 6 can adapt to material boxes of different sizes and achieve stable clamping.
[0039] Furthermore, the inclined conveyor assembly 4 is positioned between the discharge conveyor line 2 and the feeding conveyor line 9, with its inlet located below the discharge end of the feeding conveyor line 9 and its discharge end located above the inlet of the guide plate structure 3. The inclined conveyor assembly 4 smoothly lifts the preform from a lower position to a higher position, avoiding the chaos caused by direct drops.
[0040] Thus, the entire device, through the coordinated operation of the tilting hopper 7, buffer bin structure 5, feeding conveyor line 9, inclined conveyor assembly 4, and guide plate structure 3, achieves efficient transport and orderly arrangement of preforms. Specifically, the tilting hopper 7 replaces the traditional large hopper design, avoiding the problem of preforms being squeezed due to their own weight accumulating over a long period; the buffer bin structure 5 acts as a buffer and regulates the flow rate, preventing excessive pressure on the preforms during transport; and the inclined conveyor assembly 4 ensures the smooth lifting of the preforms and optimizes the transport path. Ultimately, this effectively solves the problem of preforms squeezing each other and deforming the conveyor belt due to excessive squeezing pressure caused by their own weight in the hopper, while improving material discharge efficiency and ease of operation.
