Description

Technical Field

[0001] This utility model relates to the field of mixing technology, specifically a mixing machine for raw materials in the production of PE stretch wrap film. Background Technology

[0002] PE stretch wrap film is an advanced packaging material made from linear polyethylene, metallocene polyethylene, and tackifying masterbatch. It possesses high tensile strength, tear resistance, and excellent self-adhesion, enabling it to tightly wrap items, providing dustproof, moisture-proof, and damage-proof protection. PE stretch wrap film has high transparency, facilitating the identification of packaged items and reducing delivery errors. Furthermore, it exhibits excellent elastic recovery and shrinkage properties, ensuring more secure and neat packaging. In addition, PE stretch wrap film is easy to handle and maintain during processing, saving materials, labor, and time. It is widely used in various industries, including foreign trade export, papermaking, hardware and electrical appliances, building materials, and food.

[0003] In the production of PE stretch wrap film, various raw materials typically need to be thoroughly mixed in a mixer. To ensure that no impurities are mixed into the raw materials during the mixing process, a screen is usually installed inside the mixer's feed hopper. The main function of this screen is to filter out any possible impurities to ensure the purity and quality of the raw materials. However, this screen can sometimes affect the speed at which the raw materials enter the mixer. Due to the small pore size of the screen, the raw materials may experience some obstruction as they pass through it, thus slowing down their entry into the mixer. Utility Model Content

[0004] The purpose of this invention is to provide a raw material mixer for PE stretch wrap film production, so as to solve the problem of slow feeding speed in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PE stretch wrap film production raw material mixer, comprising a mixing chamber, a drive motor fixedly installed on one side of the mixing chamber, a stirring blade fixedly installed at the output end of the drive motor, a discharge pipe fixedly installed at the bottom of the mixing chamber, a sealing cover provided at the upper end of the mixing chamber, and a positioning mechanism installed on the mixing chamber. The positioning mechanism includes a positioning frame installed on the mixing chamber, a feed inlet provided on the positioning frame, a positioning slot provided on one side of the feed inlet, and a collection box connected to the positioning slot. A lifting support leg is fixedly installed on one side of the frame, and a fixed support leg is fixedly installed on the mixing chamber. An adjusting screw is provided on the fixed support leg. A screening mechanism is installed on the positioning frame. The screening mechanism includes a positioning seat fixedly installed on the positioning frame. A spring is fixedly installed on the positioning seat. A feed funnel is fixedly installed on the upper end of the spring. A screen is fixedly installed inside the feed funnel. A vibration motor is fixedly installed on one side of the feed funnel. An impurity outlet is opened on the other side of the feed funnel. An impurity chute is connected to the impurity outlet. A gate is provided at the impurity outlet, which can block the impurity outlet.

[0006] Preferably, the positioning frame is provided with a hinge, and one end of the positioning frame is connected to the mixing chamber body via the hinge.

[0007] Preferably, the fixed support foot has a threaded hole, and the adjusting screw is connected to the fixed support foot through the threaded hole. After rotating the adjusting screw, it can move up and down.

[0008] Preferably, the fixed support leg is aligned vertically with the lifting support leg, and the upper end of the adjusting screw abuts against the lifting support leg. The collection box is connected to the positioning frame through a positioning slot.

[0009] Preferably, one end of the spring is fixed to the positioning seat, and the other end of the spring is fixed to the feed funnel, so that the spring can support the screening funnel.

[0010] Preferably, the feed hopper is provided with a sliding groove, and the gate is movably installed in the feed hopper through the sliding groove.

[0011] Preferably, the feeding funnel is mounted above the positioning frame by a spring, the feeding funnel is vertically aligned with the feeding port on the positioning frame, and the end of the impurity chute is vertically aligned with the collection box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this application, after the raw material is put into the feeding hopper, the vibration motor can be started. The start of the vibration motor will drive the screen in the feeding hopper to vibrate at a high frequency. Under the action of the high frequency vibration of the screen, the raw material can pass through the screen quickly, thereby increasing the feeding rate.

[0014] In this application, the upward rotation of the adjusting screw will cause the lifting support to be lifted, thereby raising the lifting support. This action will cause the screen to tilt relative to the collection box. After the screen tilts, the vibration motor can be restarted to cause the screen to vibrate. After the screen vibrates, the impurities on its surface will slide into the collection box along the impurity chute, making it convenient for the user to clean the impurities on the screen surface.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2As shown, this utility model provides a technical solution for a PE stretch wrap film production raw material mixer, including a mixing chamber 2, a drive motor 3 fixedly installed on one side of the mixing chamber 2, a stirring blade 5 fixedly installed at the output end of the drive motor 3, a discharge pipe 4 fixedly installed at the bottom of the mixing chamber 2, a sealing cover 1 provided at the upper end of the mixing chamber 2, a positioning mechanism 6 installed on the mixing chamber 2, and a screening mechanism 7 installed on the positioning frame 601. The screening mechanism 7 can quickly screen the raw materials, and the positioning mechanism 6 can facilitate the user to clean the impurities on the surface of the screen 705.

[0022] like Figure 2 and Figure 3 As shown, the positioning mechanism 6 includes a positioning frame 601 installed on the mixing chamber 2. The positioning frame 601 has a feed inlet 604. A positioning slot 602 is provided on one side of the feed inlet 604. A collection box 603 is connected in the positioning slot 602. A lifting support 605 is fixedly installed on one side of the positioning frame 601. A fixing support 606 is fixedly installed on the mixing chamber 2. An adjusting screw 607 is provided on the fixing support 606. A hinge 608 is provided on the positioning frame 601. One end of the positioning frame 601 is connected to the mixing chamber 2 through the hinge 608. A threaded hole is provided on the fixing support 606. The adjusting screw 607 is connected to the fixing support 606 through the threaded hole.

[0023] Specifically, after the raw materials are poured into the feed hopper 704, the vibration motor 703 can be started. Once the vibration motor 703 is started, it will start to operate and drive the screen 705 in the feed hopper 704 to vibrate at a high frequency. This high-frequency vibration of the screen 705 will cause the raw materials to pass through the screen 705 quickly under the action of vibration, thereby effectively improving the feeding speed of the raw materials.

[0024] like Figure 2 and Figure 4 As shown, the screening mechanism 7 includes a positioning seat 701 fixedly installed on the positioning frame 601. A spring 702 is fixedly installed on the positioning seat 701. A feed hopper 704 is fixedly installed on the upper end of the spring 702. A screen 705 is fixedly installed inside the feed hopper 704. A vibration motor 703 is fixedly installed on one side of the feed hopper 704. An impurity outlet 707 is opened on the other side of the feed hopper 704. An impurity chute 708 is connected to the impurity outlet 707. A gate 706 is provided at the impurity outlet 707. One end of the spring 702 is fixed on the positioning seat 701, and the other end of the spring 702 is fixed on the feed hopper 704. A chute is opened on the feed hopper 704, and the gate 706 is movably installed inside the feed hopper 704 through the chute.

[0025] Specifically, rotating the adjusting screw 607 upwards will lift the lifting support 605. After the lifting support 605 is lifted, the screen 705 will tilt towards the collection box 603. After the screen 705 tilts towards the collection box 603, the vibration motor 703 can be restarted to make the screen 705 vibrate. After the screen 705 vibrates, the impurities on the surface of the screen 705 will slide down the impurity chute 708 into the collection box 603, making it convenient for users to clean the impurities on the surface of the screen 705.

[0026] Working principle: Before mixing, the raw materials are poured into the feed hopper 704. After the raw materials are poured into the feed hopper 704, the vibration motor 703 is started, which drives the screen 705 in the feed hopper 704 to vibrate at high frequency. After the screen 705 vibrates at high frequency, the raw materials can pass through the screen 705 quickly, thereby increasing the feeding speed. After the raw materials enter the mixing chamber 2, the drive motor 3 is started. After the drive motor 3 is started, the stirring blade 5 is rotated, thereby mixing the raw materials evenly. The impurities screened out will accumulate on the surface of the screen 705. When too many impurities accumulate on the surface of the screen 705, the gate can be lifted downwards. 706. With the impurity outlet 707 in the open position, the adjusting screw 607 can be rotated upwards. Rotating the adjusting screw 607 upwards will lift the lifting support 605. After the lifting support 605 is lifted, the screen 705 will tilt towards the collection box 603. After the screen 705 tilts towards the collection box 603, the vibration motor 703 can be restarted to make the screen 705 vibrate. After the screen 705 vibrates, the impurities on the surface of the screen 705 will slide down the impurity chute 708 into the collection box 603, making it convenient for the user to clean the impurities on the surface of the screen 705.
