Description

Technical Field

[0001] This utility model relates to the field of blow molding technology, specifically to a blow molding roller floating positioning processing equipment. Background Technology

[0002] Traditional blow-molded rollers typically employ a two-step process, involving preform forming and blow molding. The basic principle is to first form a plastic preform, then place the hot preform in a blow mold, inject compressed air to inflate it until it adheres tightly to the mold cavity wall, maintaining the inflated pressure until the part cools and solidifies. The resulting hollow plastic part is then opened from the mold. However, because the two steps are performed separately, the processing efficiency is low. To improve efficiency, a one-step process for blow-molded rollers is adopted, combining injection molding and blow molding. Through the rotation and heating of the roller, plastic granules are heated and melted, directly forming the final product in the mold. However, the current one-step processing technology is still immature, resulting in inconsistent product quality. Subsequent cold working is required to further machine or treat the roller to improve its precision, surface quality, or functionality. Utility Model Content

The floating cutting assembly includes a first slide rail, a second slide rail and a cutting component. The first slide rail is fixedly installed on the frame in a horizontal direction. The second slide rail is horizontally slidably installed on the first slide rail in a direction perpendicular to the first slide rail. The cutting component is slidably installed on the second slide rail and is used to cut the blow molding rollers.

[0005] As a further improvement to the above technical solution, the floating cutting assembly also includes a floating roller and a connecting frame. The floating roller is rotatably mounted on the connecting frame, and the connecting frame is slidably connected to the first slide rail.

[0006] As a further improvement to the above technical solution, two first slide rails are provided, and the two first slide rails are arranged in parallel on the frame; each of the two first slide rails is slidably connected to a first slider, and the second slide rail is fixedly connected to both first sliders through a mounting plate.

[0007] As a further improvement to the above technical solution, the cutting component includes a drive motor and a cutting tool, wherein the stator of the drive motor is slidably mounted on the second slide rail, and its rotor is connected to the cutting tool.

[0008] As a further improvement to the above technical solution, the second slide rail is slidably connected to a second slider, and the stator of the drive motor is fixedly connected to the second slider.

[0009] As a further improvement to the above technical solution, a fixing block is fixedly installed on the second slider, and the fixing block is provided with a mounting groove. The stator of the drive motor is fixed in the mounting groove by a pipe clamp.

[0013] As a further improvement to the above technical solution, the floating cutting assembly also includes an electronically controlled switch, the output terminal of which is electrically connected to the input terminal of the cutting component.

[0014] The beneficial effects of this invention are as follows: After the blow molding roller is formed, it is placed among several roller assemblies.

[0022] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

[0023] Please see Figure 1-3The preferred embodiment of this utility model provides a blow molding roller floating positioning processing equipment, including a frame 1, a floating cutting component 2 and several roller components 3. The roller components 3 are all installed on the frame 1. The roller components 3 are used to position the blow molding roller 4. After the blow molding roller 4 is blow molded, it is placed between the roller components 3. The roller components 3 can perform preliminary positioning of the blow molding roller 4. The floating cutting component 2 is used to cut the blow molding roller 4 to further shape it and improve its accuracy.

[0024] Specifically, the floating cutting assembly 2 includes a first slide rail 21, a second slide rail 22, a cutting element 23, a floating roller 24, a connecting frame 25, and an electrical control switch. The first slide rail 21 is fixedly mounted on the frame 1 in a horizontal direction. The second slide rail 22 is horizontally slidably mounted on the first slide rail 21 in a direction perpendicular to the first slide rail 21. The cutting element 23 is slidably mounted on the second slide rail 22 and is used to cut the blow molding roller 4. The floating roller 24 is rotatably mounted on the connecting frame 25, which is slidably connected to the first slide rail 21. The output terminal of the electrical control switch is electrically connected to the input terminal of the cutting element 23. The floating roller 24 and the roller assembly 3 can jointly position the blow molding roller 4. The cutting element 23 is activated by the electrical control switch to cut the blow molding roller 4, and the roller assembly 3 drives the blow molding roller 4 to rotate, so that the cutting element 23 can remove any excess burrs or flash that may remain around the edge of the blow molding roller 4. Furthermore, during the cutting process, the second slide rail 22 can slide along the first slide rail 21, and the cutting part 23 can slide along the second slide rail 22, enabling the cutting part 23 to make slight adaptive adjustments in two vertical directions in the horizontal direction during processing. The connecting frame 25 can drive the floating roller 24 to make adaptive adjustments along the first slide rail 21, avoiding processing deviations caused by rigid contact, and achieving higher processing accuracy of the blow molding roller 4 through subsequent cold working.

[0025] Please see Figure 3 In this embodiment, two first slide rails 21 are provided, and the two first slide rails 21 are arranged parallel to each other on the frame 1. Each of the two first slide rails 21 is slidably connected to a first slider 211. A second slide rail 22 is fixedly connected to both first sliders 211 via a mounting plate 221, and a connecting bracket 25 is fixed to the mounting plate 221. The two first slide rails 21 can stably support the mounting plate 221. The arrangement of the first sliders 211 helps to reduce friction between the mounting plate 221 and the first slide rails 21, facilitating the sliding of the mounting plate 221 relative to the first slide rails 21.

[0026] The cutting component 23 includes a drive motor 231 and a cutting tool (not shown in the figure). The stator of the drive motor 231 is slidably mounted on the second slide rail 22, and its rotor is connected to the cutting tool. The output terminal of the electronic control switch is electrically connected to the input terminal of the drive motor 231. The drive motor 231 can provide a high speed, enabling the cutting tool to quickly complete tasks such as cutting and grinding of the blow molding roller 4, thereby improving work efficiency.

[0027] Specifically, the second slide rail 22 is slidably connected to the second slider 222, and the stator of the drive motor 231 is fixedly connected to the second slider 222. The setting of the second slider 222 helps to reduce the friction between the drive motor 231 and the second slide rail 22 and improve the sensitivity of the drive motor 231 sliding relative to the second slide rail 22.

[0028] In this embodiment, a fixing block 223 is fixedly installed on the second slider 222. The fixing block 223 is provided with a mounting groove 224. The stator of the drive motor 231 is fixed in the mounting groove 224 by a pipe clamp 225. The mounting groove 224 facilitates the installation of the stator of the drive motor 231 on the fixing block 223. The pipe clamp 225 can prevent the stator of the drive motor 231 from shifting under vibration, ensuring its stability.

[0029] The frame 1 includes an upper connecting plate 11, a support beam 12, and a lower connecting plate 13. The support beam 12 connects the upper connecting plate 11 and the lower connecting plate 13. There are three roller assemblies 3, one of which is located on the upper connecting plate 11 and the other two are located on the lower connecting plate 13. The three roller assemblies 3 are arranged in a triangular pattern, which can provide three triangular support points on the outer circumference of the blow molding roller 4 to prevent the blow molding roller 4 from coming off.

[0030] Specifically, the roller assembly 3 includes a base plate 31, a positioning roller 31, a connecting shaft 33, and two support arms 34. The base plate 31 is fixedly mounted on the frame 1, and the two support arms 34 are arranged opposite to each other on the base plate 31. The two ends of the connecting shaft 33 are respectively connected to the two support arms 34. The positioning roller 31 is rotatably connected to the connecting shaft 33. During cutting, the blow molding roller 4 drives the positioning roller 31 to rotate around the connecting shaft 33, so that the positioning roller 31 can move synchronously with the blow molding roller 4, reducing the friction between the two.

[0031] In this embodiment, two positioning rollers 31 are provided. The two positioning rollers 31 are located at both ends near the connecting shaft 33, and the positioning rollers 31 are spaced apart from the support arm 34 to avoid interference from the support arm 34 on the rotation of the positioning rollers 31. The arrangement of two positioning rollers 31 is beneficial to increase the contact area with the blow molding roller 4, providing better support and further positioning the blow molding roller 4.

[0032] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
