Description

Technical Field

[0001] This utility model relates to the technical field of plastic product manufacturing equipment, specifically a raw material drying device for the production of plastic packaging boxes. Background Technology

[0002] Plastic packaging boxes are a widely used packaging material, including various types such as plastic turnover boxes, food plastic turnover boxes, and beverage plastic turnover boxes. These packaging boxes are characterized by being lightweight, high-strength, non-toxic, non-polluting, waterproof, moisture-proof, resistant to acid and alkali corrosion, and resistant to oil stains. They also come in a variety of colors and have good environmental performance and secondary processing properties.

[0003] Plastic pellets are the main raw material for plastic products such as plastic packaging boxes. Through processing, they can be made into a variety of complex plastic products. However, before processing, plastic pellets are white or transparent granular substances, while the plastic products made from them can have various colors, shapes, and uses.

[0004] Existing plastic particle drying equipment typically uses agitators to stir the plastic particles, achieving uniform drying. However, existing stirring structures struggle to agitate the raw materials deposited at the bottom of the mixing drum, resulting in incomplete drying of the plastic particles at the bottom. This can lead to problems such as adhesion and deformation during subsequent processing, resulting in substandard products. Therefore, a raw material drying device for the production of plastic packaging boxes is proposed. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-4 A raw material drying device for the production of plastic packaging boxes includes a support frame 1, a drying tank 11 rotatably connected to the top of the support frame 1, a feeding hopper 13 for feeding is provided on one side of the drying tank 11 and a discharge port 15 for discharging is provided on the other side, a linkage chain 12 for linkage is provided in the middle of the tank body of the drying tank 11; multiple first scrapers 17, second scrapers 18 and third scrapers 19 for turning the raw materials are provided inside the tank body of the drying tank 11; a drying component 3 for drying the plastic particles in the support frame 1 is provided on the support frame 1, the air outlet of the drying component 3 is kept in communication with the drying tank 11, and a transmission component 2 is also provided on the support frame 1, which is connected to the linkage chain 12.

[0025] As a preferred technical solution in this embodiment: In actual use, when it is necessary to dry plastic particles, the operator can first control the plastic particles to be loaded into the drying tank 11 from the feed hopper 13. At this time, the drying component 3 can be activated to dry the plastic particles inside the drying tank 11. At the same time, the operator can control the transmission component 2 to drive the linkage chain 12 to make the drying tank 11 rotate. During the rotation of the drying tank 11, the first scraper 17, the second scraper 18 and the third scraper 19 set inside the drying tank 11 can be driven to turn and convey the plastic particle raw materials. During this process, the hot air blown out by the drying component 3 can achieve the effect of uniform drying of the plastic particles, thereby avoiding the situation where the drying is incomplete due to bottom sedimentation, which would affect subsequent processing.

[0026] In a preferred embodiment, the first scraper 17, the second scraper 18, and the third scraper 19 are sequentially arranged along the axis of the drying tank 11 on the inner wall of the drying tank 11. The multiple first scrapers 17 are arc-shaped and evenly distributed around the axis of the drying tank 11 on the inner wall of the drying tank 11. During operation, as the drying tank 11 rotates, the first scrapers 17 move in a circular motion around its axis. This circular motion lifts the plastic particles from the bottom of the drying tank 11, and when the first scraper 17 reaches a certain height, the plastic particles fall under gravity. At this point, the plastic particles disperse, and the hot air blown by the drying component 3 achieves a uniform drying effect. During this process, the plastic particles are displaced from one end of the first scraper 17 to the other, achieving a transmission effect.

[0027] In this embodiment, a preferred technical solution is as follows: both the second scraper 18 and the third scraper 19 are L-shaped and evenly arranged on the inner wall of the support frame 1 around the axis of the drying tank 11. Both the second scraper 18 and the third scraper 19 are inclined, with the inclination angle of the second scraper 18 being smaller than that of the third scraper 19. This arrangement effectively ensures that after the plastic particles are conveyed by the first scraper 17, they reach the second scraper 18, where the second scraper 18 repeats the action of the first scraper 17 to perform a second turning. The third scraper 19 does the same, until the plastic particles are conveyed to the discharge port 15, achieving the drying effect. It is worth noting that setting the inclination angle of the second scraper 18 to be smaller than that of the third scraper 19 allows the plastic particles to pass through the second scraper 18 for a longer time, increasing the drying time and further ensuring the drying effect.

[0028] As a preferred technical solution in this embodiment: the drying assembly 3 includes a mounting frame 31 for installation, a filter plate 32 for blocking dust is provided at the air inlet of the mounting frame 31, a heating element 34 for heating and a fan 33 for generating airflow are provided inside the mounting frame 31. In actual use, when the operator activates the filter plate 32, external air is drawn into the drying tank 11 through the filter plate 32. During this process, the external air is filtered by the filter plate 32, which effectively prevents dust from entering the drying tank 11. At the same time, the external air is heated by the fan 33, which effectively dries the plastic particles.

[0029] As a preferred technical solution in this embodiment: the drying tank 11 is also provided with at least two guide rails 14, and the support frame 1 is provided with a rotating wheel 16 adapted to the guide rails 14, with the guide rails 14 slidably connected to the rotating wheel 16. By providing the guide rails 14 and the rotating wheel 16, the stability of the drying tank 11 during rotation can be effectively guaranteed during use, and the output pressure of the transmission component 2 can be reduced.

[0030] As a preferred technical solution in this embodiment: the transmission assembly 2 includes a transmission motor 21 for transmission and a mounting bracket 25 for installation. The output end of the transmission motor 21 is connected to a speed reducer 22 for adjusting the speed. The output end of the speed reducer 22 is provided with a transmission wheel 23, which is connected to a transmission belt 24. The transmission belt 24 is connected to a linkage wheel 27. The mounting bracket 25 is provided with a linkage rod 26 for connecting the linkage wheel 27. The linkage rod 26 is also provided with a linkage gear 28 for linkage, which meshes with the linkage chain 12. In actual use, the operator can control the transmission motor 21 to start its output end. After the speed is adjusted by the speed reducer 22, it will drive the transmission wheel 23 to rotate. During the rotation of the transmission wheel 23, it can drive the transmission belt 24 to drive the linkage wheel 27 and the linkage rod 26 to rotate. During the rotation of the linkage rod 26, it can drive the linkage gear 28 to rotate. During the rotation of the linkage gear 28, it can drive the linkage chain 12 to make the drying tank 11 rotate.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
