Technical Field
[0001] This utility model relates to the technical field of color glaze addition devices, and in particular to an automatic weighing color glaze addition device for a bottle preform production line. Background Technology
[0002] In the bottle preform production process, the quality of the added color glaze plays a crucial role in the final appearance and color effect of the preform. Traditional color glaze addition devices often have shortcomings in several aspects. For example, they lack an effective filtration mechanism for impurities in the color glaze raw materials. Impurities mixed into the color glaze during preform production can easily lead to quality problems such as surface defects and uneven color, affecting the product's aesthetics and quality stability. Moreover, in terms of daily maintenance and cleaning of the device, components such as the tank lid of the storage tank are inconvenient to disassemble and assemble (traditionally, they are fixed by bolts). When it is necessary to clean or replace the internal components used to filter impurities, it often consumes a lot of time and effort, reducing production efficiency and increasing labor costs. Utility Model Content
[0003] This utility model mainly provides an automatic weighing type color glaze addition device for bottle preform production line.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automatic weighing type color glaze addition device for a bottle preform production line, comprising a support frame, a storage tank at the top of the support frame, a tank cover at the top of the storage tank, the tank cover and the storage tank being fixedly connected by a fixing component, a conical filter screen inside the storage tank, a circular support plate fixedly connected to the inner wall of the storage tank near the top opening, the edge of the conical filter screen overlapping the circular support plate, the fixing component comprising a locking block and a locking seat, a locking groove on the surface of the locking seat, a sliding groove on the lower surface of the locking block, a first L-shaped locking plate and a second L-shaped locking plate slidably connected inside the sliding groove, a spring fixedly connected between the first L-shaped locking plate and the second L-shaped locking plate, a first pressing plate and a second pressing plate fixedly connected to the surfaces of the first L-shaped locking plate and the second L-shaped locking plate respectively, the bottom ends of the first L-shaped locking plate and the second L-shaped locking plate being inserted into the locking groove and engaging with the locking groove.
[0005] Preferably, a feed pipe is fixedly connected to the top of the tank lid, and a sealing cap is provided on the top of the feed pipe. A discharge pipe is fixedly connected to the outer wall of the storage tank near the bottom, and an electrically controlled valve is provided on the discharge pipe.
[0006] Preferably, a weighing sensor is fixedly connected to the top of the support frame, and the weighing sensor is located below the bottom of the storage tank.
[0007] Preferably, a sealing ring is provided between the can lid and the storage tank, and the sealing ring is made of elastic rubber.
[0008] Preferably, the outer wall of the storage tank is embedded with a transparent observation window.
[0009] Preferably, a positioning rod is fixedly connected to the edge of the can lid, and a positioning block is fixedly connected to the top outer wall of the storage tank at the position corresponding to the positioning rod, with the positioning rod inserted inside the positioning block.
[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0011] 1. In this utility model, through the cooperation of a conical filter screen and a fixing component inside the storage tank, when liquid glaze is added to the storage tank, the glaze first passes through the conical filter screen. Because the conical filter screen has a certain angle of inclination and is covered with fine mesh holes, the liquid glaze can smoothly pass through the mesh holes into the storage area at the bottom of the storage tank, while any impurities present are intercepted on the surface of the filter screen. As the usage time increases and impurities accumulate, the filter screen needs to be cleaned. The fixing component allows for quick disassembly and reassembly of the tank lid. The fixing component uses a locking block and a locking seat. During operation, pressing the first and second pressing plates causes the first and second L-shaped locking plates to move towards each other, compressing the spring. At this time, the bottom ends of the first and second L-shaped locking plates disengage from the locking grooves, allowing the tank lid to be easily removed, thus facilitating the quick removal of the conical filter screen from the storage tank for cleaning later. This ensures the purity of the glaze used in bottle preform production, avoiding quality issues caused by impurities, while also facilitating the maintenance of the filter components, thus improving the practicality and production efficiency of the entire device.
[0012] 2. In this utility model, by cooperating with the positioning rod and the positioning block, when installing the can lid, the positioning rod on the edge of the can lid is aligned with the corresponding positioning block on the outer wall of the top of the storage tank and inserted therein. With the positioning effect of the positioning rod and the positioning block, the sliding groove on the card block can be quickly aligned with the card slot on the card seat, making it more convenient to insert the first L-shaped card plate and the second L-shaped card plate into the card slot. There is no need to repeatedly adjust the position, which greatly improves the efficiency of can lid installation, reduces installation time, and thus improves the operational convenience of the entire device in daily use, making it easier to carry out the color glaze addition work in bottle preform production more efficiently.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an automatic weighing type color glaze addition device for a bottle preform production line, including a support frame 1, a storage tank 2 on the top of the support frame 1, a tank cover 3 on the top of the storage tank 2, the tank cover 3 and the storage tank 2 being fixedly connected by a fixing component 6, a conical filter screen 5 inside the storage tank 2, and a circular support plate 4 fixedly connected to the inner wall of the storage tank 2 near the top opening, the edge of the conical filter screen 5 overlapping the circular support plate 4, the fixing component 6 including a locking block 601 and a locking seat 602, the surface of the locking seat 602 being open The card slot 603 is provided, and the lower surface of the card block 601 is provided with a sliding groove 604. The first L-shaped card plate 605 and the second L-shaped card plate 607 are slidably connected inside the sliding groove 604. A spring 606 is fixedly connected between the first L-shaped card plate 605 and the second L-shaped card plate 607. A first pressing plate 608 and a second pressing plate 609 are fixedly connected to the surfaces of the first L-shaped card plate 605 and the second L-shaped card plate 607, respectively. The bottom ends of the first L-shaped card plate 605 and the second L-shaped card plate 607 are inserted into the card slot 603 and engaged with the card slot 603.
[0021] like Figure 2 As shown, a feed pipe 7 is fixedly connected to the top of the tank lid 3, and a sealing cap 8 is provided on the top of the feed pipe 7. A discharge pipe 13 is fixedly connected to the outer wall of the storage tank 2 near the bottom, and an electric control valve 14 is provided on the discharge pipe 13. The feed pipe 7 is used to add color glaze into the storage tank 2, and the sealing cap 8 can prevent external impurities from entering and contaminating the color glaze. The discharge pipe 13, together with the electric control valve 14, can automatically control the opening and closing of the valve.
[0022] like Figure 3 As shown, a weighing sensor 15 is fixedly connected to the top of the support frame 1. The weighing sensor 15 is located below the bottom of the storage tank 2. Here, the weighing sensor 15 can monitor the weight change of the glaze in the storage tank 2 in real time. By connecting with the control system, the amount of glaze added each time can be accurately controlled to ensure the consistency of product color and improve product quality.
[0023] like Figure 3 As shown, a sealing ring 9 is provided between the can lid 3 and the storage tank 2. The sealing ring 9 is made of elastic rubber. Here, the sealing ring 9 can enhance the sealing between the can lid 3 and the storage tank 2, prevent the glaze from leaking and causing waste or environmental pollution, and at the same time prevent external air from entering and causing the glaze to oxidize and deteriorate.
[0024] like Figure 3 As shown, a transparent observation window 12 is embedded in the outer wall of the storage tank 2. The remaining amount and state of the glaze in the storage tank 2 can be directly observed through the observation window 12, which facilitates timely replenishment of glaze or detection of abnormalities and improves the convenience of production management.
[0025] like Figure 3 As shown, a positioning rod 10 is fixedly connected to the edge of the can lid 3, and a positioning block 11 is fixedly connected to the top outer wall of the storage tank 2 at the position corresponding to the positioning rod 10. The positioning rod 10 is inserted into the inside of the positioning block 11. The cooperation between the positioning rod 10 and the positioning block 11 can quickly and accurately position the can lid 3 on the storage tank 2, ensuring that the locking block 601 of the fixing component 6 is accurately aligned with the locking seat 602, improving installation efficiency and reducing operation difficulty.
[0026] The usage and working principle of this device are as follows: First, liquid glaze is added to the storage tank 2 through the feed pipe 7. During its entry into the storage tank 2, the glaze passes through a conical filter screen 5. The conical filter screen 5 uses its tilt angle and fine mesh structure to intercept and filter impurities in the glaze, allowing pure glaze to fall into the storage area at the bottom of the storage tank 2, ensuring the quality of the glaze used in subsequent bottle preform production. When glaze needs to be added to the bottle preform production line, the control unit (which can be connected to relevant control modules that coordinate with the entire bottle preform production line, not shown in detail in the figure) analyzes and judges based on the preset glaze addition amount and the real-time weight data of the storage tank 2 and the overall weight of the glaze fed back by the weighing sensor 15. If the preset addition amount is not reached, the control unit will send a command to keep the electrically controlled valve 14 on the discharge pipe 13 in the open state (or open it to a certain degree, adjusted according to process requirements), allowing the glaze to flow out from the discharge pipe 13 and be added to the bottle preform production stage. During this process, the weighing sensor 15 continuously monitors weight changes and feeds back data. Once the preset amount is reached... When the amount of glaze to be added is set, the control unit immediately closes the electronic control valve 14 to stop the addition of glaze, thereby precisely controlling the amount of glaze added to the preform each time. As the usage time increases, when it is necessary to clean the impurities on the surface of the conical filter screen 5, the operator presses the first pressing plate 608 and the second pressing plate 609 in the fixing assembly 6, causing the first L-shaped clamping plate 605 and the second L-shaped clamping plate 607 to move towards each other and compress the spring 606. Then, the can lid 3 can be easily removed, and the conical filter screen 5 can be taken out of the storage tank 2 for cleaning. After cleaning, the can lid 3 is installed back onto the storage tank 2 through the fixing assembly 6 in the reverse order. During installation, the positioning rod 10 and the positioning block 11 are used to quickly and accurately connect the components, ensuring that the device can continue to operate normally. During daily use, the operator can check the remaining amount of glaze in the storage tank 2 at any time through the transparent observation window 12. If it is found that the sealing cap 8 is not properly closed or the sealing ring 9 is not sealing well, it should be dealt with in time to ensure the overall sealing and normal operation of the device. In summary, through the coordinated operation of various components, the system achieves precise control over the addition of color glaze to the preform production line, impurity filtration, convenient equipment maintenance, and stable operation, thus ensuring the quality and efficiency of preform production.
