Description

Technical Field

[0001] The invention belongs to the technical field of plastic part trimming, and in particular relates to an automatic trimming processing device for plastic parts. Background Art

[0002] The automatic trimming equipment for plastic parts is a device used to improve the production efficiency and quality of plastic products. It automatically completes the trimming process of plastic parts through mechanical means. Compared with the traditional manual trimming method, it not only greatly improves the work efficiency, but also effectively reduces the errors and safety risks caused by manual operation.

[0003] However, this type of equipment also has some problems during use. For example, the large amount of scraps generated during the trimming process are relatively difficult to recycle, because these scraps are of different sizes and shapes. In addition, the equipment works at a high speed and with a high degree of automation, which makes it difficult to collect and properly dispose of these wastes in time. This not only affects the cleanliness of the workshop, but also causes waste of raw materials and potential environmental problems.

[0004] Since the edges of the cut plastic scraps are relatively sharp, if they are directly put into a bag, the sharp corners will easily puncture the bag, and the resistance to pouring the scraps out of the bag is also relatively high, which makes the conventional method of recycling the scraps difficult.

[0005] To this end, we propose an automated trimming equipment for plastic parts to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the problem in the prior art that the conventional recycling of plastic scraps is relatively difficult, and to propose an automatic trimming processing equipment for plastic parts.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an automatic trimming processing equipment for plastic parts, comprising a motor frame and a drum frame, wherein a motor is fixedly installed inside the motor frame, a drum is rotatably installed inside the drum frame, a heating sleeve is covered on the outside of the drum, the heating sleeve does not contact the drum, the heating sleeve is fixedly installed on the upper part of the drum frame, and the motor is connected to the drum in a transmission manner.

[0008] The motor is used to drive the drum to rotate, and the heating sleeve is used to heat the drum. The scraps are placed in the drum, and the plastic scraps are rolled and heated in the drum, so that the plastic scraps evolve into a spherical shape and are then discharged downward through the drum, avoiding puncture of the bag during recycling and also facilitating pouring out of the bag for reuse after transportation.

[0009] Preferably, an upper hopper is fixedly mounted on the upper portion of the motor frame, the lower portion of the upper hopper is a curved pipe, and the lower space of the upper hopper is communicated with the internal space of the drum.

[0010] The plastic scraps are poured into the upper hopper, and then the plastic scraps are guided into the rotating drum through the upper hopper, which makes loading convenient.

[0011] Preferably, the motor frame includes a first frame body and a fixing sleeve, the fixing sleeve is located inside the first frame body, and the first frame body and the fixing sleeve are fixedly connected as a whole.

[0012] Preferably, the drum frame includes a second frame body and a guide wheel, and the guide wheel is rotatably connected to the inside of the second frame body.

[0013] When the motor drives the guide wheel to rotate, the guide wheel drives the rotating drum to rotate, which facilitates the plastic scraps to roll along the rotating drum, thereby facilitating the evolution of the plastic scraps into a spherical structure.

[0014] Preferably, the rotating drum comprises a drum body and a transmission sleeve, a pair of the transmission sleeves are provided, and the transmission sleeves are fixedly sleeved on the outside of the drum body.

[0015] The driving sleeve facilitates the rotation and installation of the drum and the drum frame.

[0016] Preferably, the drum further comprises an annular heat sink, and the annular heat sink is evenly and fixedly connected to the outside of the drum.

[0017] The annular heat sink is used to increase the heat dissipation area of ​​the cylinder, which facilitates the heat dissipation and forming of plastic scraps before cutting.

[0018] Preferably, the rotating drum further comprises a feed nozzle, and the feed nozzle is fixedly mounted on the outside of the drum.

[0019] The unloading nozzle is used to guide the leftover plastic parts processed inside the cylinder into the target container, which facilitates unloading.

[0020] In summary, the technical effects and advantages of the present invention are as follows:

[0021] 1. Use the motor to drive the drum to rotate, and use the heating sleeve to heat the drum. Put the plastic scraps into the drum, so that the plastic scraps roll and heat in the drum, so that the plastic scraps evolve into a spherical shape, and then discharge downward through the drum, avoiding puncturing the bag during recycling and bagging, and also facilitating pouring out of the bag for reuse after transportation.

[0022] 2. When the motor drives the guide wheel to rotate, the guide wheel drives the rotating drum to rotate, which facilitates the rolling of the plastic scraps along the rotating drum, thereby facilitating the evolution of the plastic scraps into a spherical structure.
