Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically a feeding device for injection molding production of plastic pallets. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment that uses plastic molds to make various shapes of plastic products from thermoplastic or thermosetting materials. Injection molding machines are the most widely used processing machinery in the plastics processing industry. Not only can a large number of products be directly produced by injection molding machines, but they are also key equipment in the injection stretch blow molding process. Injection molding machines require a feeding device to operate.

[0003] Existing technology publication CN223431920U discloses a feeding device for injection molding of plastic pallets, including an extrusion mechanism and a feeding assembly. The feeding assembly is fixedly connected to the top of the extrusion mechanism, and a receiving assembly is provided at the upper end of the feeding assembly. A blockage-relief assembly is provided in the middle of the feeding assembly and the receiving assembly. The blockage-relief assembly is fixedly connected to the feeding assembly and movably connected to the receiving assembly. The receiving assembly includes a main feeding hopper sleeved on the upper end of the feeding assembly, and several evenly distributed vibration buffer springs are connected to the bottom of the main feeding hopper. Due to the setting of the receiving assembly, this utility model can achieve continuous high-frequency vibration of the hopper with the cooperation of the feeding assembly, so that the position of the lower discharge port can be continuously changed, thereby reducing the probability of blockage. Especially during the continuous reciprocating motion, the raw material accumulated inside can move relative to the blockage-relief assembly, thereby achieving the effect of blockage relief.

[0004] However, existing feeding devices for plastic pallet injection molding production suffer from several drawbacks. The plastic granules contain a large amount of powder and debris, and the granules are difficult to screen during preparation. This leads to over-melting when the debris enters the injection molding machine, affecting the quality of the pallet injection molding. Furthermore, while vibration can reduce the probability of clogging, it is difficult to control the feeding speed and quantity, resulting in poor feeding performance. Therefore, we propose a new feeding device for plastic pallet injection molding production. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding device for injection molding production of plastic pallets, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for injection molding production of plastic pallets, comprising: a feeding mechanism including a material preparation hopper, a feeding hopper welded to one side of the material preparation hopper, a screening screen installed on the inner side of the feeding hopper, and a discharge port opened on one side of the feeding hopper; a feeding mechanism including a feeding frame bolted to the back of the material preparation hopper, a feeding motor installed on the top of the feeding frame, a feeding shaft fixed to the drive end of the feeding motor via a coupling, a spiral blade welded to the bottom end of the feeding shaft, a cleaning sleeve threadedly connected to the outer side of the feeding shaft, a loosening wall welded to the outer side of the cleaning sleeve, and a cleaning scraper welded to one end of the loosening wall.

[0007] Preferably, a mounting plate is welded to the bottom of the material preparation hopper, and a mounting base is bolted to the bottom of the mounting plate.

[0008] Preferably, an injection molding tube is welded to the bottom of the mounting base, and an injection molding motor is installed at one end of the injection molding tube.

[0009] Preferably, the material preparation hopper gradually decreases in size from top to bottom, and the inner surface of the material preparation hopper is smooth.

[0010] Preferably, the spiral blade has a spiral structure and is located in the center of the inside of the hopper.

[0011] Preferably, there are two cleaning scrapers, and both cleaning scrapers are in contact with the inner wall of the preparation hopper.

[0012] This utility model provides a feeding device for injection molding production of plastic pallets, which has the following advantages: This type of feeding device for plastic pallet injection molding production, through the setting of a feeding hopper and a screening screen, allows workers to add plastic granules into the feeding hopper. At this time, the plastic granules slide along the screening screen, and the powder and debris in the plastic granules can be screened out by the screening screen. The screened powder and debris can then be discharged through the discharge port. Subsequently, the plastic granules enter the preparation hopper for preparation. This allows the feeding device to screen the plastic granules during the preparation process, avoiding over-melting of the plastic granules during the hot melting process, thus improving the quality of pallet injection molding production.

[0013] This type of feeding device for injection molding of plastic pallets, through a feeding mechanism, involves a feeding motor that drives the feeding shaft to rotate during feeding, while the spiral blades follow suit. The spiral blades then transport the plastic granules, preventing blockages during feeding. The rotation speed of the spiral blades also controls the feeding rate. Simultaneously, the cleaning sleeve drives the loosening wall and cleaning scraper to rotate with the feeding shaft. The loosening wall agitates the plastic granules, making them more dispersed, while the cleaning scraper scrapes the inner wall of the hopper, allowing the plastic granules to flow more smoothly, thus improving feeding efficiency.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a feeding device for injection molding production of plastic pallets, comprising, The feeding mechanism 1 includes a preparation hopper 101, a feeding hopper 106 welded to one side of the preparation hopper 101, a screening screen 107 installed on the inner side of the feeding hopper 106, and a discharge port 108 opened on one side of the feeding hopper 106. The feeding mechanism 2 includes a feeding frame 201 bolted to the back of the preparation hopper 101. A feeding motor 202 is installed on the top of the feeding frame 201. A feeding shaft 203 is fixed to the drive end of the feeding motor 202 via a coupling. A spiral blade 207 is welded to the bottom end of the feeding shaft 203. A cleaning sleeve 204 is threaded to the outside of the feeding shaft 203. A loosening wall 205 is welded to the outside of the cleaning sleeve 204. A cleaning scraper 206 is welded to one end of the loosening wall 205.

[0018] Furthermore, a mounting plate 102 is welded to the bottom of the material preparation hopper 101, and a mounting base 103 is bolted to the bottom of the mounting plate 102, so that the material preparation hopper 101 and the mounting base 103 can be firmly fixed together through the mounting plate 102.

[0019] Furthermore, an injection molding tube 104 is welded to the bottom of the mounting base 103. An injection molding motor 105 is installed at one end of the injection molding tube 104. By starting the injection molding motor 105, the injection molding motor 105 drives the injection molding component to run, so that the injection molding tube 104 can better deliver plastic for injection molding operations.

[0020] Furthermore, the material preparation hopper 101 gradually decreases in size from top to bottom, and the inner surface of the material preparation hopper 101 is smooth. The material preparation hopper 101 can better prepare materials, allowing the plastic granules to flow better.

[0021] Furthermore, the spiral blade 207 has a spiral structure and is located in the center of the material preparation hopper 101. The feeding motor 202 drives the feeding shaft 203 to rotate, and the spiral blade 207 rotates accordingly. At this time, the spiral blade 207 can play the role of conveying plastic granules and avoid the phenomenon of blockage of plastic granules during the feeding process.

[0022] Furthermore, two cleaning scrapers 206 are provided, both of which are in contact with the inner wall of the preparation hopper 101. The cleaning scrapers 206 scrape the inner wall of the preparation hopper 101, allowing the plastic particles to flow more smoothly.

[0023] Working Principle: After installation, the installation, fixation, and safety precautions of this utility model are first checked. When using the feeding device for plastic pallet injection molding production, the operator adds plastic granules into the feeding hopper 106. At this time, the plastic granules slide along the screening screen 107, and the powder and debris in the plastic granules can be screened out by the screening screen 107. The screened powder and debris can be discharged through the discharge port 108. Then, the plastic granules enter the preparation hopper 101 for preparation, so that the feeding device can screen the plastic granules during the preparation process. During feeding, the feeding motor 202 of the feeding mechanism 2 drives the feeding shaft 203 to rotate. The spiral blade 207 rotates accordingly, at which point it can convey plastic granules, preventing blockage during feeding. The rotation speed of the spiral blade 207 also controls the feeding amount. Simultaneously, the cleaning sleeve 204 drives the loosening wall 205 and the cleaning scraper 206 to rotate together with the feeding shaft 203. The loosening wall 205 agitates the plastic granules, making them more dispersed, while the cleaning scraper 206 scrapes the inner wall of the preparation hopper 101, allowing the plastic granules to flow more smoothly. This completes the application of this utility model. This utility model has a simple structure and is safe and convenient to use.
