[0002] There are various types of rubber products. The basic technological process of rubber products using general solid rubber - raw rubber as raw materials includes six basic processes: plasticating, mixing, calendering, extruding, molding, and vulcanizing. The processing technological process of rubber mainly solves the contradiction between plasticity and elasticity. Through various technological means, elastic rubber is made into plasticated rubber with plasticity, and then various compounding agents are added to make semi-finished products, and then the semi-finished products with plasticity are vulcanized into rubber products with high elasticity and good physical and mechanical properties.

[0003] Currently, in the production process of rubber products, the common feeding method of rubber raw materials mainly relies on a conveying cylinder to convey rubber raw materials into the production equipment, which mainly consists of a feeding bin, a feeding pipe, and a discharge port. A stirring rod is pushed by a motor to accelerate the speed of the rubber raw materials in the feeding pipe from the feeding port to the discharge port. There are some inconveniences in actual operation and there is room for improvement. For example, a buffer mechanism is not provided in the discharge ports of most feeding pipes. The plastic particles directly fall from the discharge port into the production equipment. The falling speed of the materials is not easy to control during the discharging process, and a good buffer effect cannot be obtained when the rubber products are falling, which is easy to cause blockage during discharging. The feeding quality of the rubber raw materials is poor and it does not have the function of buffer for material falling.

[0004] Now, a new feeding buffer mechanism for rubber product production is proposed to solve the above problems. Content of the Utility Model

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The feeding buffer mechanism for rubber product production not only realizes the function of material falling buffer, but also realizes the function of convenient cover removal and maintenance, and also realizes the function of reminding to supplement materials.

[0016] (1) By providing an outer cover, a bottom plate, a hinge, a corrugated sleeve, and a spring, the rubber product falls from the hopper into the feeding pipe. The rotating shaft in the feeding pipe is driven by a driving motor to accelerate the rubber product forward in the feeding pipe to the discharge port at its bottom end, and finally it is output from the discharge port to the next process. By sleeving the outer cover outside the discharge port, the material falls into multiple bottom plates at the bottom end of the outer cover. Since the bottom plate is hinged to the hinge, during this period, the bottom plate opens due to the pressure of the falling material, enabling the rubber product to obtain a better buffering effect during the falling process. Since the spring at the top end of the bottom plate is connected to the inner wall of the outer cover, when the falling of the material stops, the bottom plate is no longer under pressure and returns to its original position under the retraction of the spring. This not only reduces the impact amplitude during the falling of the material, but also has a good buffering effect on the falling of the rubber raw material, reduces the probability of blockage at the discharge port of the material, improves the feeding quality of the rubber raw material, and realizes the function of buffer during the falling of the material;

[0017] (2) By providing a first flange, a second flange, a third flange, a fourth flange, a top cover, a feeding slot, and a sealing ring, the third flange on the feeding slot is connected to the fourth flange at the outer bottom end of the hopper, and then firmly fixed in the feeding slot at the top end of the top cover by the sealing ring at the bottom end of the hopper, so that the hopper will not shake when the rubber product is fed. During the entire feeding process, the rotating shaft in the feeding pipe driven by the driving motor conveys the rubber product from the hopper to the discharge port, and then the feeding pipe and the top cover are fixed together by the first flange at the front end of the feeding pipe and the second flange at the front end of the rotating shaft. When a failure occurs to the rotating shaft and the material stops being conveyed, after removing the bolts connecting the first flange and the second flange, the feeding pipe and the top cover are separated, which is convenient for the operator to directly judge and repair the rotating shaft inside the feeding pipe, reduces the situation that the feeding speed of the rubber product is affected and blockage occurs due to the damage of the driving motor or the rotating shaft, improves the feeding and discharging efficiency of the rubber product, and realizes the function of being convenient for removing the cover for maintenance;

[0018] (3) By providing an infrared signal transmitting part, an infrared signal receiving part, a power cord, a controller, and an alarm, the rubber product falls from the hopper into the feeding pipe. During the feeding process of the rubber product, the infrared signal transmitting part and the infrared signal receiving part on both sides of the hopper can monitor the feeding situation of the material inside the hopper in real time. After the infrared signal transmitting part emits a signal, the signal is received by the infrared signal receiving part, so as to obtain the feeding situation of the material inside the hopper. When the rubber product is being fed, the infrared light is in a cut-off state. When the infrared light is connected, the signals sent by the infrared signal transmitting part and the infrared signal receiving part are transmitted to the controller through the power cord, and then output to the alarm at the front end of the controller. The alarm sound emitted by the alarm can remind the operator to replenish the material in time, avoiding the situation that the entire production process of the rubber product is affected due to problems during the feeding of the rubber product, and realizing the function of reminding to replenish the material.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1: Please refer to Figures 1-4 , a feeding buffer mechanism for rubber product production, including a feeding pipe 1, a hopper 2 is arranged above the feeding pipe 1, a discharge port 3 is arranged on the right side of the bottom end of the feeding pipe 1, a driving motor 4 is arranged on the left side of the feeding pipe 1, a rotating shaft 5 is arranged inside the feeding pipe 1, and a buffer assembly for reducing the impact of falling materials is arranged outside the discharge port 3;

[0026] Please refer to Figures 1-4 , a feeding buffer mechanism for rubber product production further includes a buffer assembly. The buffer assembly includes an outer housing 6, the outer housing 6 is arranged outside the discharge port 3, twelve groups of bottom plates 7 are arranged at the bottom end of the outer housing 6, hinges 8 are respectively arranged on both sides of the bottom end of the outer housing 6, a corrugated sleeve 9 is arranged at the top end of the bottom plate 7, and a spring 10 is arranged inside the corrugated sleeve 9;

[0027] The vertical center lines of the outer housing 6 and the discharge port 3 coincide. The bottom plates 7 are symmetrically distributed with respect to the vertical center line of the outer housing 6 and are arranged at equal intervals. The hinge 8 is hingedly connected to the bottom plate 7. The bottom ends of the outer housing 6 and the bottom plate 7 are flush. The corrugated sleeve 9 is elastic. The top ends of the corrugated sleeve 9 and the spring 10 are connected to the inner wall of the outer housing 6, and the bottom ends of the corrugated sleeve 9 and the spring 10 are connected to the top end of the bottom plate 7.

[0028] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, the rubber product falls from the hopper 2 into the feed pipe 1. The rotating shaft 5 in the feed pipe 1 is driven by the drive motor 4 to accelerate the rubber product in the feed pipe 1 to the discharge port 3 at its bottom end, and finally outputs from the discharge port 3 to the next process. By sleeving the outer housing 6 outside the discharge port 3, the material falls into the multiple bottom plates 7 at the bottom end of the outer housing 6. Since the bottom plate 7 is hingedly connected to the hinge 8, during this period, the bottom plate 7 opens due to the pressure of the material falling, so that the rubber product has a better buffering effect when falling. Since the spring 10 at the top end of the bottom plate 7 is connected to the inner wall of the outer housing 6, when the material falling stops, the bottom plate 7 is no longer under pressure and resets again under the retraction of the spring 10, which not only reduces the impact amplitude during material falling, but also has a good buffering effect on the rubber raw material falling, reduces the probability of material blockage at the discharge port 3, improves the feeding quality of the rubber raw material, and reduces the impact force of its feeding.

[0029] Embodiment 2: A first flange 11 is provided at the front end of the feed pipe 1. A second flange 12 is provided at the top end of the first flange 11. A top cover 15 is provided at the top of the feed pipe 1. A feed chute 21 is fixedly connected to the top of the top cover 15. A third flange 13 is fixedly connected to the top end of the feed chute 21. A fourth flange 14 is fixedly connected to the bottom end outside the hopper 2. A sealing ring 22 is provided below the fourth flange 14. The feed pipe 1 and the top cover 15 are adapted in shape and size and are hingedly connected. The sealing ring 22 and the feed chute 21 are adapted in shape and size, and the second flange 12 is connected to the top cover 15.

[0030] Specifically, as Figure 1 and Figure 4As shown in the figure, the third flange 13 on the feed chute 21 is connected to the fourth flange 14 at the outer bottom end of the hopper 2, and then firmly fixed in the feed chute 21 at the top end of the top cover 15 by the sealing ring 22 at the bottom end of the hopper 2, so that the hopper 2 will not shake when rubber products are fed. During the entire feeding process, the rotating shaft 5 in the feeding pipe 1 is driven by the driving motor 4 to convey the rubber products from the hopper 2 to the discharge port 3. Then, the feeding pipe 1 and the top cover 15 are fixed together by the first flange 11 at the front end of the feeding pipe 1 and the second flange 12 at the front end of the rotating shaft 5. When the rotating shaft 5 fails and the material conveying stops, the bolts connecting the first flange 11 and the second flange 12 are removed to separate the feeding pipe 1 and the top cover 15, which is convenient for the operator to directly judge and repair the rotating shaft 5 inside the feeding pipe 1, reducing the situation of affecting the feeding speed of rubber products and causing blockage due to the breakdown of the driving motor 4 or the rotating shaft 5, and the feeding efficiency is higher.

[0031] Embodiment 3: An infrared signal transmitting part 16 is arranged on the left side of the hopper 2, an infrared signal receiving part 17 is arranged on the right side of the hopper 2, a controller 19 is arranged above the front end of the hopper 2, an alarm 20 is arranged at the front end of the controller 19, power supply lines 18 are respectively arranged on the left and right sides of the controller 19, and the infrared signal transmitting part 16, the infrared signal receiving part 17, the controller 19, and the alarm 20 are electrically connected. The infrared signal transmitting part 16 and the infrared signal receiving part 17 penetrate through the side of the hopper 2 and extend to the inside, and the positions of the infrared signal transmitting part 16 and the infrared signal receiving part 17 correspond one by one;

[0032] Specifically, as Figure 1 and Figure 4 shown in the figure, the rubber products fall from the hopper 2 into the feeding pipe 1. During the feeding of the rubber products, the infrared signal transmitting part 16 and the infrared signal receiving part 17 on the left and right sides of the hopper 2 can monitor the feeding situation of the materials inside the hopper 2 in real time. After the signal is sent by the infrared signal transmitting part 16, it is received by the infrared signal receiving part 17, so that the feeding situation of the materials inside the hopper 2 can be obtained. When the rubber products are fed, the infrared light remains in a cut-off state. When the infrared light is connected, the signals sent by the infrared signal transmitting part 16 and the infrared signal receiving part 17 are transmitted to the controller 19 through the power supply line 18, and then output to the alarm 20 at the front end of the controller 19 by the controller 19. The alarm sound emitted by the alarm 20 can remind the operator to replenish the materials in time, avoiding affecting the entire production process of rubber products due to problems during the feeding of rubber products, and the feeding prompt is more convenient.

[0033] Working principle: When the utility model is in use, first, the rubber product drops from the hopper 2 into the feeding pipe 1. The rotating shaft 5 in the feeding pipe 1 is driven by the driving motor 4 to accelerate the rubber product to move forward in the feeding pipe 1 to the discharge port 3 at its bottom end, and finally is output from the discharge port 3 to the next link. By sleeving an outer cover 6 outside the discharge port 3, the material drops into a plurality of bottom plates 7 at the bottom end of the outer cover 6. Since the bottom plates 7 are hinged to the hinges 8, during this period, the bottom plates 7 open due to the pressure of the material falling, so that the rubber product can obtain a better buffering effect when falling. Since the springs 10 at the top ends of the bottom plates 7 are connected to the inner wall of the outer cover 6, when the material falling stops, the bottom plates 7 are no longer under pressure and reset again under the retraction of the springs 10, which not only reduces the impact amplitude during material falling, but also has a good buffering effect on the rubber raw material falling, reduces the probability of blockage at the discharge port 3 of the material, improves the feeding quality of the rubber raw material, and reduces the impact force of its feeding. The third flange 13 on the feeding chute 21 is connected to the fourth flange 14 at the outer bottom end of the hopper 2, and is firmly fixed in the feeding chute 21 at the top end of the top cover 15 by the sealing ring 22 at the bottom end of the hopper 2, so that the hopper 2 will not shake when the rubber product is feeding. During the whole feeding process, the rotating shaft 5 in the feeding pipe 1 driven by the driving motor 4 conveys the rubber product from the hopper 2 to the discharge port 3, and then the feeding pipe 1 and the top cover 15 are fixed together by the first flange 11 at the front end of the feeding pipe 1 and the second flange 12 at the front end of the rotating shaft 5. When a failure occurs to the rotating shaft 5 and the material conveying stops, the bolts connecting the first flange 11 and the second flange 12 are removed to separate the feeding pipe 1 and the top cover 15, which is convenient for the operator to directly judge and repair the rotating shaft 5 inside the feeding pipe 1, reduces the situation of affecting the feeding speed of the rubber product and causing blockage due to the breakdown of the driving motor 4 or the rotating shaft 5, and has a higher feeding efficiency. The rubber product drops from the hopper 2 into the feeding pipe 1. During the feeding of the rubber product, the infrared signal transmitting part 16 and the infrared signal receiving part 17 on the left and right sides of the hopper 2 can monitor the feeding situation of the material inside the hopper 2 in real time. After the signal is sent by the infrared signal transmitting part 16, it is received by the infrared signal receiving part 17, so that the feeding situation of the material inside the hopper 2 can be obtained. When the rubber product is feeding, the infrared light remains in a cut-off state. When the infrared light is connected, the signals sent by the infrared signal transmitting part 16 and the infrared signal receiving part 17 are transmitted to the controller 19 through the power line 18, and then output to the alarm 20 at the front end of the controller 19. The alarm sound emitted by the alarm 20 can remind the operator to replenish the material in time, avoiding affecting the whole rubber product production process due to problems during the feeding of the rubber product, and the feeding prompt is more timely and convenient.
