[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1

[0033] This embodiment provides a feeding device for rubber pellets, such as Figure 1-5 As shown, the feeding device for rubber molding pellets includes a feeding hopper 1, a mounting plate 6 arranged at the bottom of the feeding hopper 1, a driving component 2 arranged between the mounting plate 6 and the feeding hopper 1 for driving the feeding hopper 1 to feed, a stirring component 3 arranged inside the feeding hopper 1 for stirring the raw materials, and a protective component 4 arranged at the top of the feeding hopper 1 for preventing the material from splashing out. The protective component 4 includes a splash-proof bucket 41 installed on the top of the feeding hopper 1, a feed port 42 opened at the top of the splash-proof bucket 41, an L-shaped block 43 fixedly arranged at the bottom of the splash-proof bucket 41 and clamped with the top of the feeding hopper 1, and a fixing component 44 arranged on the L-shaped block 43 for fixing the splash-proof bucket 41 and the feeding hopper 1.

[0034] During use, the driving component 2 is first used to drive the rubber and plastic raw materials inside the feeding hopper 1 to feed the raw materials, which is convenient for the subsequent extrusion of the raw materials. At the same time, the stirring component 3 is used to stir the raw materials inside the feeding hopper 1 to avoid the rubber and plastic raw materials from agglomerating inside. In order to avoid the raw materials from splashing out from the top of the feeding hopper 1 during the stirring process, causing waste of raw materials, it can be protected by the protective component 4. The splash-proof bucket 41 is first connected to the top edge of the feeding hopper 1 along the L-shaped block 43, and the splash-proof bucket 41 is used to achieve a splash-proof effect, and the feed port 42 is used to facilitate feeding.

[0035] Specifically, the fixing assembly 44 includes a mounting box 441 fixedly arranged on the side of the L-shaped block 43 away from the feeding hopper 1, a fixing hole 442 provided on the L-shaped block 43 and the feeding hopper 1, a fixing rod 443 slidably inserted into the fixing hole 442, a telescopic spring 444 fixedly arranged on the side of the fixing rod 443 away from the feeding hopper 1 and fixedly connected to the mounting box 441, a telescopic rod 445 sleeved inside the telescopic spring 444 and fixedly connected at both ends to the fixing rod 443 and the mounting box 441 respectively, a slide groove 446 provided on the mounting box 441 and the L-shaped block 43, an L-shaped slider 447 fixedly arranged on the side of the fixing rod 443 close to the mounting box 441 and sliding inside the slide groove 446, and a pull ring 448 fixedly arranged on the side of the L-shaped slider 447 close to the mounting box 441; in order to avoid During the process, the feeding hopper 1 vibrates, causing the anti-splash bucket 41 to be unstable and shaken. The anti-splash bucket 41 and the feeding hopper 1 can be fixed by the fixing component 44. First, the L-shaped slider 447 is moved along the slide groove 446 box away from the side of the feeding hopper 1, and then the fixing rod 443 inside the installation box 441 is driven to move out of the fixing hole 442 on the feeding hopper 1, so as to facilitate the clamping of the anti-splash bucket 41. After the clamping is completed, the L-shaped slider 447 is released, so that the telescopic spring 444 inside the installation box 441 drives the telescopic rod 445 to squeeze the fixing rod 443, so that the fixing rod 443 is slidably inserted into the inside of the fixing hole 442, thereby fixing the anti-splash bucket 41 and the feeding hopper 1. In order to achieve more convenient adjustment of the position of the L-shaped slider 447, a pull ring 448 can be set, and a reasonable adjustment effect can be achieved by pulling the pull ring 448.

[0036] Among them, in order to achieve reasonable drive feeding; the driving component 2 includes a discharge pipe 22 fixedly arranged at the bottom of the feeding hopper 1 and connected to the feeding hopper 1, an auger 23 arranged inside the discharge pipe 22 for transmitting materials, and a driving motor 21 fixedly arranged on the mounting plate 6 and connected to the output end of the auger 23; when feeding is required, the driving motor 21 is first turned on to drive the auger 23 inside the discharge pipe 22 to rotate, and then the raw materials falling from the top of the feeding hopper 1 are transmitted and fed inside the discharge pipe 22 through the auger 23.

[0037] Furthermore, the stirring component 3 includes a stirring blade 31 arranged at an upper position inside the feeding hopper 1 for stirring the material, and a stirring motor 32 fixedly arranged on the side of the feeding hopper 1 for driving the stirring blade 31 to rotate; in order to avoid the agglomeration of the mixed rubber and plastic raw materials after entering the feeding hopper 1, the stirring component 3 can be used to stir the raw materials inside the feeding hopper 1, and the stirring motor 32 can be turned on to drive the stirring blade 31 to rotate, thereby achieving the effect of rotating and stirring the raw materials.

[0038] Example 2

[0039] like Figure 6 As shown, the difference from Example 1 is that the feeding device for rubber and plastic pellets further includes a slow-release component 5 arranged at the bottom of the stirring component 3 inside the feeding hopper 1 to avoid clogging. The slow-release component 5 includes a slot opened on the inner wall of the feeding hopper 1, a connecting plate 52 slidably engaged with the inside of the slot, a filter 51 fixedly arranged at the bottom of the connecting plate 52 and located inside the feeding hopper 1, and a clip 53 fixedly arranged at the top of the connecting plate 52 and engaged with the top of the feeding hopper 1. The top of the clip 53 contacts the bottom of the anti-splash bucket 41; in order to prevent the rubber and plastic raw materials on the top of the feeding hopper 1 from falling due to their own gravity More raw materials enter the bottom discharge pipe 22, causing the bottom discharge pipe 22 to be blocked, which in turn leads to the problem of transmission failure of the auger 23. The fallen raw materials can be filtered and slowly released through the slow-release component 5. The connecting plate 52 is slid along the card slot and clamped on the inner wall of the feeding hopper 1, so that the top card plate 53 is clamped on the top of the feeding hopper 1, thereby achieving the effect of placing the filter screen 51 inside the feeding hopper 1. At this time, when the raw materials fall to the bottom of the feeding hopper 1, they will be filtered and slowly released through the filter screen 51, achieving the effect of preventing blockage. After use, the filter screen 51 can be moved upward for easy cleaning.
