Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices for hot press molding machines, specifically a feeding device for a hot press molding machine. Background Technology

[0002] The feeding device of a hot press molding machine is a key component for achieving automated production. Its design must consider material characteristics, production efficiency, and molding accuracy. It performs the feeding process by precisely conveying sheet-like, granular, powdered, or preformed materials to the hot press mold station. However, existing hot press molding machine feeding devices have some shortcomings, such as:

[0003] Application No.: CN202021683073.2 describes a feeding unit for a plastic and rubber hot press molding machine. This equipment improves upon existing feeding units of plastic and rubber hot press molding machines by injecting raw materials into the mold through a mechanical method instead of manual labor before the hot press mold. A shaking device is also installed at the bottom of the mold to ensure full contact between the raw material and the mold cavity, preventing defective products and significantly improving production efficiency. However, in actual use, this equipment struggles to intercept and sieve larger particles of raw material, which may lead to the conveying of unsuitable, larger particles during the feeding process, thus reducing the fineness of the raw material.

[0004] Therefore, we propose a feeding device for a hot press molding machine to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding device for a hot press molding machine, so as to solve the problem mentioned in the background art that most feeding devices of hot press molding machines on the market are unable to intercept and screen large particles of raw materials, resulting in coarse raw materials.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for a hot press molding machine, comprising a feeding bin body and a drive motor connected inside the feeding bin body;

[0007] The drive motor is connected to the left side of the inside of the feed hopper body, and the right side of the drive motor is connected to the first gear, and the outer side of the first gear is meshed with the second gear. A set of crushing shafts is connected to the right side of both the first gear and the second gear.

[0008] The right end of the drive motor is provided with a first bevel gear set, and the bottom of the first bevel gear set is connected to a drive shaft. The bottom of the drive shaft is connected to a second bevel gear set. The middle of the drive shaft is provided with a third bevel gear set, and the right end of the third bevel gear set is provided with a striking rod. The top of the striking rod is provided with a filter plate.

[0009] The bottom of the feed hopper is connected to an inclined plate, and the bottom left side of the inclined plate is connected to the discharge pipe. The discharge pipe is equipped with an auger shaft, and the left side of the auger shaft is connected to the second bevel gear set.

[0010] By driving the first and second bevel gear sets and other mechanisms simultaneously with the drive motor, the third bevel gear set can also drive the striking rod to rotate while the crushing shaft is processing the raw materials. This causes the striking rod to periodically strike the filter screen plate, making it vibrate up and down. This vibration of the filter screen plate screens the raw materials. Furthermore, by enabling the filter screen plate and the auger shaft to work simultaneously while the crushing shaft is crushing the raw materials, the efficiency of the equipment during use is increased.

[0011] As a preferred technical solution of this utility model, a partition is provided on the left side of the inside of the feeding hopper body, and two sets of crushing shafts pass through the partition and are connected to the right side of the feeding hopper body.

[0012] The above technical solution can isolate the drive motor and other equipment by the partition, thereby preventing raw materials from leaking onto the chain and avoiding jamming of the first bevel gear set, the second bevel gear set and the third bevel gear set.

[0013] As a preferred technical solution of this utility model, a feeding trough is connected to the top of the feeding hopper body, and the feeding trough is inverted trapezoidal, and the feeding trough is located at the top of the two sets of crushing shafts.

[0014] The above technical solution allows the raw materials to be poured out through the feeding trough when entering the feeding hopper, thereby increasing the stability of the equipment during feeding.

[0015] As a preferred technical solution of this utility model, a telescopic shaft is connected inside the feed hopper body, and the top of the telescopic shaft is fixedly connected to the filter screen plate, and the bottom of the telescopic shaft is fixedly connected to the feed hopper body.

[0016] The above technical solution makes the feed hopper body more stable when fixing the filter screen plate, and makes the striking rod more stable when driving the filter screen plate, thus increasing the stability of the equipment during use.

[0017] As a preferred technical solution of this utility model, a circular slot is provided at the bottom left side of the inclined plate, and the inclined plate is connected to the discharge pipe through the circular slot, and a discharge port is connected to the bottom right side of the discharge pipe.

[0018] The above technical solution enables the equipment to discharge materials more stably, thereby increasing the convenience of material discharge.

[0019] As a preferred technical solution of this utility model, the bottom of the feeding hopper body is connected to a foot, and the foot is fixedly connected to the bottom of the feeding hopper body.

[0020] The above technical solution enables the base to support the feed hopper body, thereby increasing the stability of the equipment during operation.

[0021] As a preferred technical solution of this utility model, the drive motor is fixedly connected to the feed hopper body, and the second gear is fixedly connected to the feed hopper body through a bearing seat.

[0022] The above technical solution enables the device to be more securely fixed, thereby increasing the stability of the device during operation.

[0023] Compared with the prior art, the beneficial effects of this utility model are: by driving the first bevel gear set and the second bevel gear set to run simultaneously by the drive motor, the third bevel gear set can also drive the striking rod to rotate while the crushing shaft is processing the raw materials. This causes the striking rod to periodically strike the filter screen plate, making it vibrate up and down. This causes the filter screen plate to vibrate and screen the raw materials. Furthermore, by enabling the filter screen plate and the auger shaft to work simultaneously while the crushing shaft is crushing the raw materials, the efficiency of the equipment during use is increased.

[0024] Furthermore, by connecting the telescopic shaft to the filter screen, the feed hopper body can be more stable when fixing the filter screen, and the striking rod can be more stable when moving the filter screen, thus increasing the stability of the equipment during use.

[0025] Furthermore, fixing the second gear with a bearing housing makes the device more secure when fixed, thereby increasing the stability of the device during operation. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] To address the difficulty in screening raw materials in existing technologies, the following solution is disclosed. Please refer to [link / reference]. Figure 1-5 This utility model provides a technical solution: a feeding device for a hot press molding machine, including a feeding bin body 1 and a drive motor 3 connected inside the feeding bin body 1;

[0034] The drive motor 3 is connected to the left side of the inside of the feed hopper body 1, and the right side of the drive motor 3 is connected to the first gear 4, and the outer side of the first gear 4 is meshed with the second gear 5. A set of crushing shafts 6 are connected to the right side of both the first gear 4 and the second gear 5.

[0035] The right end of the drive motor 3 is provided with a first bevel gear set 7, and the bottom of the first bevel gear set 7 is connected to a drive shaft 8, and the bottom of the drive shaft 8 is connected to a second bevel gear set 9. The middle part of the drive shaft 8 is provided with a third bevel gear set 10, and the right end of the third bevel gear set 10 is provided with a striking rod 11, and the top of the striking rod 11 is provided with a filter plate 13.

[0036] The bottom of the feed hopper body 1 is connected to an inclined plate 15, and the bottom left side of the inclined plate 15 is connected to the discharge pipe 16. The discharge pipe 16 is equipped with an auger shaft 12, and the left side of the auger shaft 12 is connected to the second bevel gear set 9.

[0037] When the drive motor starts, the drive motor 3 will drive the first gear 4 and the second gear 5 to rotate. Since the second gear 5 meshes with the first gear 4, the first gear 4 and the second gear 5 will simultaneously drive the crushing shaft 6 to rotate. This causes the two crushing shafts 6 to rotate in opposite directions to crush the raw material. The crushed raw material falls onto the top of the filter screen plate 13. Since the right end of the drive motor 3 is equipped with a first bevel gear set 7, the first bevel gear set 7 will drive the drive shaft 8 to rotate. This will cause the drive shaft 8 to drive the third bevel gear set 10 to rotate. This will cause the third bevel gear set 10 to drive the striking rod 11 to rotate. This will cause the striking rod 11 to strike the filter screen plate 13, causing the filter screen plate 13 to vibrate. This will intercept the larger raw material particles and allow them to pass through the screen, while other raw material particles will fall through the gaps in the filter screen plate 13 to the bottom of the feed hopper body 1. After screening, the raw material will fall onto the top of the inclined plate 15.

[0038] A partition is provided on the left side inside the feed hopper body 1, and two sets of crushing shafts 6 pass through the partition and are connected to the right side of the feed hopper body 1; a feed trough 2 is connected to the top of the feed hopper body 1, and the feed trough 2 is inverted trapezoidal and located at the top of the two sets of crushing shafts 6; a telescopic shaft 14 is connected inside the feed hopper body 1, and the top of the telescopic shaft 14 is fixedly connected to the filter screen plate 13, and the bottom of the telescopic shaft 14 is fixedly connected to the feed hopper body 1.

[0039] A circular slot is provided at the bottom left side of the inclined plate 15, and the inclined plate 15 is connected to the discharge pipe 16 through the circular slot. The discharge pipe 16 is connected to the bottom right side of the discharge port 17. The bottom of the feeding bin body 1 is connected to the foot 18, and the foot 18 is fixedly connected to the bottom of the feeding bin body 1. The drive motor 3 is fixedly connected to the feeding bin body 1, and the second gear 5 is fixedly connected to the feeding bin body 1 through the bearing seat.

[0040] When the striking rod 11 strikes the filter plate 13, the telescopic shaft 14 connected to the four sides of the filter plate 13 will extend and retract, thereby limiting the four sides of the filter plate 13 and preventing the filter plate 13 from shifting due to excessive vibration.

[0041] Working principle: When using the feeding device of the hot press molding machine, the drive motor 3 is started first, which drives the first gear 4 and the second gear 5 to rotate. Since the second gear 5 meshes with the first gear 4, the first gear 4 and the second gear 5 will simultaneously drive the crushing shaft 6 to rotate, thereby crushing the raw material. The crushed raw material falls onto the top of the filter plate 13. Since the right end of the drive motor 3 is equipped with the first bevel gear set 7, the first bevel gear set 7 will drive the drive shaft 8 to rotate, thereby driving the drive shaft 8 to rotate the third bevel gear set 10, thereby driving the third bevel gear set 10 to rotate the striking rod 11, causing the striking rod 11 to strike the filter plate 13, thereby causing the filter plate 13 to vibrate, and the raw material falls onto the top of the inclined plate 15 after screening.

[0042] When the drive motor 3 rotates, the drive shaft 8 will drive the second bevel gear set 9 to rotate, which in turn drives the auger shaft 12 to rotate, causing the raw material at the top of the inclined plate 15 to fall into the discharge pipe 16 and be conveyed by the auger shaft 12 to complete the feeding work.

[0043] When the striking rod 11 strikes the filter plate 13, the telescopic shaft 14 connected to the four sides of the filter plate 13 will extend and retract, thereby limiting the four sides of the filter plate 13 and preventing the filter plate 13 from shifting due to excessive vibration.

[0044] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
