Description

Technical Field

[0001] This utility model relates to the technical field of TPE granule production equipment, specifically to a mixing device for producing TPE granules. Background Technology

[0002] Plastic products are generally produced by injection molding from melted plastic granules (thermoplastic elastomers TPE / TPR). Before injection molding, depending on the specific production requirements, other plastic granules and other auxiliary materials need to be mixed into the plastic granules, so thorough stirring and mixing are necessary.

[0003] Patent application CN202322038236.1 discloses a mixing and stirring device for plastic granule production, including a base, a mixing tank, a first stirring structure, a lifting top cover structure, and a second stirring structure. The base has multiple supporting legs at its bottom and an annular groove on its upper surface. The bottom of the mixing tank is slidably connected to the groove via multiple sliding connectors. The top of the mixing tank is open, and a discharge port with a valve is located on one side of the mixing tank near its bottom. This invention can comprehensively mix various plastic materials, improving mixing uniformity compared to previous methods. It also facilitates subsequent rinsing and cleaning of the mixing device's interior and components, effectively preventing material residue from remaining inside and on the mixing components, thus significantly improving the quality of plastic granule production. It is highly practical.

[0004] This patent uses multiple power sources to drive the stirring components after stirring, which wastes energy; at the same time, when the stirring tank is separated from the stirring components, the material inside the stirring tank cannot be preliminarily cleaned, resulting in a large amount of labor required for cleaning.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a mixing device for producing TPE granules that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted:

[0008] A TPE granule mixing apparatus, comprising:

[0009] A mixing tank; a mixing mechanism for mixing materials inside the mixing tank; a separation mechanism for separating and cleaning the mixing tank from the mixing mechanism.

[0010] The stirring mechanism includes: a forward and reverse rotating motor; a stirring rod fixedly mounted on the motor; and a mounting platform for fixing the motor.

[0011] The separation mechanism includes: a support frame; a reciprocating lead screw; a transmission mechanism that synchronously drives the stirring mechanism to slide on the reciprocating lead screw when the motor rotates in the opposite direction; and the fixed platform is slidably mounted on the support frame.

[0012] Furthermore, the transmission mechanism includes: a gear fixedly connected coaxially to the motor; a one-way rotating component meshing with one side of the gear; both the gear and the one-way rotating component are rotatably mounted on a fixed platform.

[0013] Furthermore, the unidirectional rotating component includes: a gear ring that meshes with the gear; a ratchet rotatably mounted in the inner cavity of the gear ring; and a pawl hinged to the inner wall of the gear ring; the pawl and the ratchet are meshed with each other.

[0014] Furthermore, the ratchet has a slider that engages with the reciprocating screw; the ratchet engages with the reciprocating screw through the slider.

[0015] Furthermore, a crossbar for horizontal stirring of the material is fixedly installed on one side of the stirring rod; a scraper for hanging material on the inner wall of the mixing tank is fixedly installed on the other side of the stirring rod.

[0016] Furthermore, the support frame is hinged to the mixing tank via a double-headed hinge rod.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a mixing device for producing TPE granules by setting a stirring mechanism to stir the material in the mixing tank; after the stirring is completed, the motor that drives the stirring mechanism to rotate in the opposite direction drives the separation mechanism to separate the stirring component from the mixing tank, thereby saving an additional power source; at the same time, by setting one side of the stirring rod as a horizontal bar and the other side of the stirring rod as a scraper, the separation mechanism can clean the material in the tank to a large extent before separating the stirring mechanism from the mixing tank, thereby saving cleaning time.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a mechanism is referred to as being "fixed to" another mechanism, it can be directly on the other mechanism or there may be an intervening mechanism. When a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intervening mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it can be directly set on the other mechanism or there may be an intervening mechanism at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0026] like Figures 1 to 4 As shown, this utility model discloses a TPE granule mixing device, comprising: a mixing tank 1; a mixing mechanism 2 for mixing the materials in the mixing tank 1; and a separation mechanism 3 for separating and cleaning the mixing tank 1 from the mixing mechanism 2. In this utility model, the separation mechanism 3 separates the mixing mechanism 2 from the mixing tank 1 after mixing, thereby facilitating the cleaning of the materials in the tank by the staff.

[0027] The stirring mechanism 2 includes: a forward and reverse motor 21; a stirring rod 22 fixedly mounted on the motor; and a fixed platform 23 for fixing the motor. When it is necessary to stir the material, the forward and reverse motor 21 is started to rotate forward by adding material into the stirring tank 1. Since the stirring rod 22 is fixedly connected to the motor, it drives the stirring rod 22 to rotate and stir inside the material tank.

[0028] A crossbar 221 for horizontal stirring of materials is fixedly installed on one side of the stirring rod 22; a scraper 222 for hanging materials on the inner wall of the mixing tank 1 is fixedly installed on the other side of the stirring rod 22; thus, when the stirring rod 22 rotates, the crossbar 221 will horizontally stir the materials in the tank. This horizontal stirring method can effectively break the layered distribution of materials during the stirring process, promote full mixing between materials, and thus improve the uniformity of stirring; when the scraper 222 passes through the inner wall of the mixing tank 1, it will scrape off the materials adhering to the inner wall, preventing the materials from forming dead corners or accumulating during the stirring process.

[0029] Separation mechanism 3 includes: a support frame 31; a reciprocating screw 32; a transmission mechanism 33 that synchronously drives the stirring mechanism 2 to slide on the reciprocating screw 32 when the motor rotates in the reverse direction; a fixed platform 23 is slidably mounted on the support frame 31; the transmission mechanism 33 includes: a gear 331 fixedly connected to the motor on the same axis; a one-way rotating component 332 meshing with one side of the gear 331; both the gear 331 and the one-way rotating component 332 are rotatably mounted on the fixed platform 23; after stirring is completed, the motor is reversed, and the motor drives the gear 331 to rotate in the reverse direction. The wheel 331 rotates; the gear 331 synchronously drives the one-way rotating component 332 to rotate; since the reciprocating screw 32 meshes with the ratchet 3322 inside the one-way rotating component 332, the one-way rotating component 332 will move up and down along the reciprocating screw 32 when it rotates. At the same time, the gear 331 and the one-way rotating component 332 are both rotatably mounted on the fixed platform 23; thus, when the one-way rotating component 332 moves up and down, the stirring mechanism 2 fixedly mounted on the fixed platform 23 can move up and down with it and separate from the stirring tank 1.

[0030] It should be noted that the specific structure of the one-way component includes: a gear ring 3321 meshing with the gear 331; a ratchet 3322 rotatably mounted on the inner cavity of the gear ring 3321; a pawl hinged to the inner wall of the gear ring 3321; the pawl 3323 meshing with the ratchet 3322; a slider inside the ratchet 3322 meshing with the reciprocating screw 32; the ratchet 3322 meshing with the reciprocating screw 32 via the slider; when the gear 331 rotates, it drives the gear ring 3321 to rotate, because the gear ring 3321 is hinged with the pawl 3323 and the pawl 3323 is hinged to the gear ring 3321. The ratchet 3322 inside the gear ring 3321 engages, so when the motor rotates forward, the gear ring 3321 drives the pawl 3323 to rotate, and the pawl 3323 slides along the teeth of the ratchet 3322; thus, it does not drive the ratchet 3322 to rotate; therefore, the stirring mechanism 2 will not move when the motor rotates forward; when the motor rotates in reverse, the pawl 3323 will abut against the back of the teeth of the ratchet 3322, thereby driving the ratchet 3322 to move synchronously, and then when the motor rotates in reverse, the ratchet 3322 slides up and down on the reciprocating screw 32 to drive the stirring mechanism 2 to separate from the stirring tank 1.

[0031] It is important to emphasize that the stirring rod 22 continues to rotate even when the motor reverses. A scraper 222 is fixedly installed on one side of the stirring rod 22. When the stirring component separates from the mixing tank 1, it will rotate and separate, thereby cleaning the material adhering to the inner wall of the mixing tank 1 and saving the cleaning time of the staff.

[0032] The support frame 31 is hinged to the mixing tank 1 via a double-headed hinge rod 4. By hinged the hinged tank to the support frame 31 via the double-headed hinge rod 4, the mixing tank 1 can be manually pulled laterally when cleaning the cleaning tank, thereby moving it away from directly below the mixing mechanism 2, making manual cleaning safer.

[0033] Working principle: When mixing TPE granules, materials are manually added to the mixing tank 1, and the forward and reverse motor 21 is started to rotate forward. Since the stirring rod 22 is fixedly connected to the motor, it drives the stirring rod 22 to rotate and stir inside the material tank. After stirring is completed, the motor that drives the stirring mechanism 2 rotates in the reverse direction to drive the separation mechanism 3 to separate the stirring components from the mixing tank 1, thus saving additional power. At the same time, by setting one side of the stirring rod 22 as a crossbar 221 and the other side of the stirring rod 22 as a scraper 222, the separation mechanism 3 can clean the material in the tank to a greater extent before separating the stirring mechanism 2 from the mixing tank 1, thus saving cleaning time.
