Description

Technical Field

[0001] This utility model belongs to the field of bottle preform positioning and processing technology, and specifically relates to a simple bottle preform tooth positioning device. Background Technology

[0002] With the continuous changes in the current consumer market environment, customers have increasingly higher requirements for packaging and quality, and at the same time, the demand for high-end plastic positioning bottles is growing. Many plastic positioning bottles on the market currently have bottle shapes and nozzles that require directional positioning. Therefore, blow molding machines must pre-position the preform nozzles before blow molding to obtain products that meet customer requirements.

[0003] Currently, the positioning methods of plastic preform nozzle positioning devices disclosed in existing technologies generally employ mechanical positioning. For example, patents with authorization announcement number CN218256714U (titled "A Novel Fully Automatic Nozzle Positioning Mechanism for Blow Molding Machines") and CN215396822U (titled "A Simple Preform Nozzle Positioning Device") are examples. These technical solutions not only have complex structural designs and high production and usage costs, but also a relatively high failure rate. Therefore, our company provides a simple preform nozzle positioning device to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a simple preform tooth positioning device that is not only simple in structure and low in production and use costs, but also can achieve precise positioning of the preform tooth.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A simple preform nozzle positioning device includes a preform holder and a preform. The preform is mounted on the preform holder. A rotating mechanism for driving the preform holder to rotate is provided at the bottom of the preform holder. A preform nozzle is provided at the lower part of the preform. A preform nozzle positioning component is provided on one side of the preform holder, and the preform nozzle positioning component corresponds to the preform nozzle on the preform. The preform nozzle positioning component includes a linear guide rail, a support seat slidably mounted on the linear guide rail, a support rod fixedly connected to the support seat, and a nozzle positioning plate connected to the support rod. The front end of the nozzle positioning plate mates with the preform nozzle. A telescopic spring is fixedly connected to the support seat, and a positioning block is connected to the end of the telescopic spring opposite to the support seat.

[0007] As a preferred embodiment, a through-hole is provided on the side of the support base near the telescopic spring, and the telescopic spring passes through the through-hole and is fixedly connected to the inner wall of the support base.

[0008] In a preferred embodiment, the positioning block is disposed on one side of the linear guide rail, and the telescopic spring is fixedly connected to the inner side of the positioning block.

[0009] As a preferred embodiment, a support base is provided at the bottom of the linear guide rail and the positioning block, and the linear guide rail and the positioning block are both fixedly installed on the support base.

[0010] As a preferred embodiment, the positioning block includes a horizontal positioning seat and a supporting column, which are integrally connected, and the supporting column is disposed on the horizontal positioning seat.

[0011] As a preferred embodiment, a first positioning hole is provided on the horizontal positioning seat, and a second positioning hole is provided on the support column. The fixing bolt is connected to the support base through the first positioning hole, and the pin screw is connected to the telescopic spring through the second positioning hole.

[0012] As a preferred embodiment, the support rod includes a horizontal support rod and a vertical support rod. The front end of the horizontal support rod is rotatably connected to the toothed positioning plate via a pin, and the bottom of the vertical support rod is fixedly installed on the support base.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In use, as the bottle preform's teeth turn towards the tooth positioning mechanism, the tooth positioning plate is compressed by the bottle preform and slides backward along the linear guide. Simultaneously, the telescopic spring is compressed during this backward sliding. When the bottle preform's teeth turn directly in front of the tooth positioning plate, the rotating mechanism stops, and the bottle preform can no longer act on the tooth positioning plate. At this point, the telescopic spring, during its return to its original position, moves the tooth positioning plate forward, causing the front end of the tooth positioning plate to engage with the bottle preform's teeth, thus achieving rapid positioning of the bottle preform's teeth. This bottle preform tooth positioning assembly structure is not only very simple in structure and has low production and usage costs, but also provides highly accurate positioning.

Detailed Implementation

[0017] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0018] Please see Figure 1 As shown, this utility model embodiment provides a simple preform nozzle positioning device, including a preform holder 10 and a preform 20. The preform 20 is mounted on the preform holder 10. A rotating mechanism (not shown in the figure) for driving the preform holder 10 to rotate is provided at the bottom of the preform holder 10. A preform nozzle 21 is provided at the lower part of the preform 20. A preform nozzle positioning component 30 is provided on one side of the preform holder 10, and the preform nozzle positioning component 30 corresponds to the preform nozzle 21 on the preform 20. In this embodiment, the rotating mechanism can be a gear drive (refer to CN 215396822 U) or a sprocket drive (refer to CN 218256714 U). In use, the preform 20 is fixedly mounted on the preform holder 10, so that the preform 20 can rotate with the preform holder 10. When it is necessary to position the preform nozzle 21, the rotating mechanism drives the preform 20 on the preform holder 10 to rotate (see...). Figure 1 (The rotation direction indicated by the arrow on the bottle preform 20) When the bottle preform tooth 21 turns to the side of the bottle preform tooth positioning component 30, the rotation mechanism stops working. At this time, the bottle preform tooth 21 is positioned by the bottle preform tooth positioning component 30. In this embodiment, the bottle preform tooth positioning component 30 is not only simple in structure and low in production and use costs, but also can accurately position the bottle preform tooth 21.

[0019] Please see Figure 1 As shown, the preform nozzle positioning assembly 30 specifically includes a linear guide rail 31, a support base 32 slidably mounted on the linear guide rail 31, a support rod 33 fixedly connected to the support base 32, and a nozzle positioning plate 34 connected to the support rod 33. The front end of the nozzle positioning plate 34 engages with the preform nozzle 21. A telescopic spring 35 is fixedly connected to the support base 32, and a positioning block 36 is connected to the end of the telescopic spring 35 opposite to the support base 32. Specifically, in this embodiment, as the preform nozzle 21 on the preform 20 turns to the nozzle positioning mechanism 4, the nozzle positioning plate 34 is compressed by the pressure of the preform 20 and slides backward along the linear guide rail 31. At the same time, during the backward sliding of the nozzle positioning plate 34, the telescopic spring 35 is in a compressed state. When the preform nozzle 21 turns to the front of the nozzle positioning plate 34, the rotating mechanism stops working, and the preform 20 cannot act on the nozzle positioning plate 34. At this time, the extension spring 35 can drive the nozzle positioning plate 34 forward during the restoration process, so that the front end of the nozzle positioning plate 34 is engaged in the preform nozzle 21 (see...). Figure 1(The forward and backward movement direction indicated by the arrow on the middle support 32) thereby completing the rapid positioning of the preform tooth 21. This preform tooth positioning component 30 is not only very simple in structure and low in production and use cost, but also very accurate in positioning.

[0020] Please see Figure 1 As shown, a through-hole 37 is provided on the side of the support base 32 near the telescopic spring 35. The telescopic spring 35 passes through the through-hole 37 and is fixedly connected to the inner wall of the support base 32. A positioning block 36 is provided on one side of the linear guide rail 31, and the telescopic spring 35 is fixedly connected to the inner side of the positioning block 36. A support base 38 is provided at the bottom of the linear guide rail 31 and the positioning block 36, and both the linear guide rail 31 and the positioning block 36 are fixedly installed on the support base 38. In this embodiment, by providing a through-hole 37 on the support base 32, the telescopic spring 35 can be installed inside the support base 32, which saves installation space and also protects the telescopic spring 35. The positioning block 36 can be used to install and limit the telescopic spring 35. The support base 38 provides a solid and stable foundation for the entire preform tooth positioning assembly 30, ensuring that the equipment can operate stably and preventing movement or tilting due to external forces or other reasons.

[0021] Please see Figure 1 As shown, the positioning block 36 specifically includes a horizontal positioning seat 361 and a support column 362, which are integrally connected. The support column 362 is mounted on the horizontal positioning seat 361. The horizontal positioning seat 361 has a first positioning hole (not shown in the figure), and the support column 362 has a second positioning hole (not shown in the figure). A fixing bolt is connected to the support base 38 through the first positioning hole, and a pin screw is connected to the telescopic spring 35 through the second positioning hole. In this embodiment, the horizontal positioning seat 361 and the support column 362 can be used to fix and install the support base 38 and the telescopic spring 35.

[0022] Please see Figure 1 As shown, the support rod 33 includes a horizontal support rod 331 and a vertical support rod 332. The front end of the horizontal support rod 331 is rotatably connected to the tooth positioning plate 34 via a pin, and the bottom of the vertical support rod 332 is fixedly installed on the support base 32. The support rod 33 enables the positioning and installation of the tooth positioning plate 34. In this embodiment, the shape of the front end of the tooth positioning plate 34 matches the shape of the preform tooth 21. For example, if the preform tooth 21 has an arc-shaped structure, then the front end of the tooth positioning plate 34 also has an arc-shaped structure; if the preform tooth 21 has a square structure, then the front end of the tooth positioning plate 34 also has a square structure.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
