Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] To address the technical problem of the difficulty in cleaning scraper bars, this invention provides a plastic granule preheating device that enables convenient cleaning while ensuring effective use.

[0028] It should be noted that the plastic granule preheating device described in this utility model is used for, but not limited to, plastic granules. For ease of explanation, this utility model only uses the application of a plastic granule preheating device in a plastic granulation equipment as an example. The principle of the plastic granule preheating device applied to other types of equipment is essentially the same as that applied to plastic granulation equipment, and will not be described in detail here.

[0029] Please see Figure 1 - Figure 7 , Figure 1 This is a schematic diagram of a plastic granule preheating device according to an embodiment of the present invention. The plastic granule preheating device includes a tank 100, a sealing door 200, a stirring assembly 300, and a scraping assembly 400. A square groove 110 is provided on one side of the tank 100, and a guide surface 120 is provided inside the opening of the square groove 110. The sealing door 200 is detachably connected to the square groove 110. The stirring assembly 300 includes a motor 310 and a stirring rod 320. The motor 310 is located at the bottom of the tank 100 and is connected to the stirring rod 320 for transmission. The scraping assembly 400 is located on one side of the stirring rod 320, and when one side of the scraping assembly 400 rotates to the guide surface 120, it elastically abuts against the guide surface 120.

[0030] In this embodiment, an open cleaning structure is constructed by opening a square groove 110 on one side of the tank 100 and setting a sealing door 200. Specifically, when the scraping component 400 is rotated to the side of the square groove 110, the scraping component 400 can be cleaned manually, which is more convenient and can effectively ensure the scraping effect.

[0031] In one embodiment, please refer to Figure 1 - Figure 7 The scraping assembly 400 includes a frame 410 and a blade 420. The frame 410 has a groove 411 on one side near the inner wall of the tank 100. One side of the blade 420 extends into the groove 411 and is elastically connected to the bottom of the groove 411. When the opposite side of the blade 420 extends freely, it can extend out of the guide surface 120.

[0032] In this embodiment, when the cutter 420 rotates to the inner wall of the tank 100, it abuts against the inner wall of the tank 100 and scrapes off the residue adhering to the inner wall of the tank 100; when the cutter 420 rotates to the inner side of the sealing door 200, it abuts against the inner side of the sealing door 200. The extension and retraction of the cutter 420 is achieved within a small degree of freedom due to the influence of the contact surface.

[0033] In one embodiment, please refer to Figure 7 The frame 410 includes a frame 412 and a reinforcing rod 413, with the reinforcing rod 413 fixedly connected to the inner side of the frame 412.

[0034] In this embodiment, the reinforcement rod 413 helps to improve the stability of the frame 412.

[0035] In one embodiment, please refer to Figure 2 The scraping components 400 are arranged in pairs, and one side of each scraping component 400 is fixedly connected to the outer wall of the stirring rod 320.

[0036] In this embodiment, the scraping components 400 are arranged in pairs to improve the scraping effect and avoid the residue of plastic residue.

[0037] In one embodiment, please refer to Figure 1 - Figure 7 The square groove 110 has sealing grooves 111 on its opposite side walls. A sealing strip 130 is embedded in the sealing groove 111. The two opposite sides of the sealing door 200 extend into the square groove 110 and squeeze the sealing strip 130 until the sealing strip 130 compacts the sealing groove 111.

[0038] In this embodiment, the opening and closing of the sealing door 200 can be achieved by vacuuming or by hinged connection to one side of the inner wall of the square groove 110. The specific connection method shall be subject to the usage requirements.

[0039] In one embodiment, please refer to Figure 1 - Figure 3 The bottom of the square groove 110 is provided with a positioning groove 112, and the bottom end of the sealing door 200 extends into the positioning groove 112 and is in transition fit with the positioning groove 112.

[0040] In this embodiment, the bottom end of the sealing door 200 extends into the positioning groove 112 and transitions into the positioning groove 112, which helps to improve the sealing performance. However, at the same time, the sealing door 200 needs to be removed and placed periodically to avoid excessive wear caused by too frequent use, which may lead to the replacement of the sealing door 200.

[0041] In one embodiment, please refer to Figure 1 The stirring rod 320 includes a rotating shaft 321 and stirring blades 322, with the stirring blades 322 distributed along the axial direction of the rotating shaft 321.

[0042] In one embodiment, please refer to Figure 7 The stirring blades 322 are set at an angle.

[0043] In this embodiment, the inclined arrangement of the stirring blade 322 helps to improve the stirring effect.

[0044] In one embodiment, please refer to Figure 7 The stirring blade 322 is a heating plate.

[0045] In this embodiment, the stirring blade 322 is a heating plate, which facilitates the reduction of structural layout; specifically, both the rotating shaft 321 and the stirring blade 322 can be set to be hollow, and heat transfer can be achieved by arranging resistance wires.

[0046] In one embodiment, please refer to Figure 1 The top of the tank 100 is provided with an openable and closable top cover 140, and the bottom of the tank 100 is provided with a support foot 150.

[0047] To better understand this utility model, the following is combined with... Figures 1 to 7 The technical solution of this utility model is described in detail below:

[0048] First, plastic granules are placed inside the tank 100. Then, the stirring rod 320 and scraping assembly 400 are driven to rotate by the motor 310 to achieve heating, stirring, and scraping of the inner wall of the tank 100. Due to the guide surface 120, the blade 420 can rotate and abut against the inner wall of the tank 100 more smoothly when it comes into contact with the guide surface 120, avoiding jamming. When it is necessary to clean the blade 420, the sealing door 200 can be opened to manually clean the blade 420 that protrudes from the square groove 110 without removing the blade 420, which is more convenient and can effectively ensure its performance.

[0049] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
