Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a material conveying device. Background Art

[0002] In the production process of food and beverages, a colloid mill is needed to grind walnut kernels and other materials to produce walnut milk beverages. In the related art, the opening and closing of the baffle at the bottom of the trough is used as the switch to control the material discharge. When the baffle at the bottom of the trough is opened, the walnut kernels are transported to the colloid mill, otherwise, the walnut kernels are stopped; because the frequency and time of the baffle opening and closing are difficult to control, if the baffle is opened for too long or too frequently, it is easy to cause the motor to overload and stop and the blade to be damaged due to material blockage; if the baffle is opened for too short a time or too low a frequency, it will reduce production efficiency, and the ratio of water to material will also be affected, reducing product yield. Utility Model Content

[0003] In view of this, the utility model provides a material conveying device to solve the problem that the frequency and time of the baffle opening and closing are difficult to control. If the baffle is opened for too long or the frequency is too high, the motor may be overloaded and shut down due to material blockage, and the blade may be damaged. If the baffle is opened for too short a time or the frequency is too low, the production efficiency will be reduced, and the ratio of water to material will also be affected, thereby reducing the product yield.

[0004] The utility model provides a material conveying device, comprising a material trough, a baffle mechanism, a buffer trough and a control mechanism; a first discharge port is provided at the bottom of the material trough; the baffle mechanism is arranged at the position where the first discharge port is located, and has a closed position for closing the first discharge port and an open position for opening the first discharge port; the buffer trough is located below the material trough, the top is connected with the first discharge port, and a second discharge port is provided on one side, and the second discharge port is used to be connected with the top feed port of the colloid mill; a spiral pushing component is provided in the buffer trough, and the spiral pushing component is used to continuously push the material to the second discharge port; the control mechanism is communicatively connected with the baffle mechanism, and is used to detect the material stock in the buffer trough, and control the closing and opening of the baffle mechanism.

[0005] Beneficial effects: by adding a buffer trough between the material trough and the colloid mill, the material can be continuously and evenly fed into the colloid mill, and the ratio of the material to water entering the colloid mill can be controlled according to the optimal process requirements, so that the product quality is effectively improved; compared with the intermittent direct feeding of the material trough into the colloid mill, which causes unstable current operation of the colloid mill motor or causes the motor to shut down due to overload, the utility model ensures the stability of the colloid mill motor current, extends the service life of the colloid mill, and ensures that the colloid mill can operate continuously and stably for a long time, avoiding impact on the power grid; the material inventory in the buffer trough is detected by the control mechanism, and the closing and opening of the baffle mechanism are controlled, so as to realize automatic control of the buffer trough feeding, which can avoid excessive material storage in the buffer trough and interrupted feeding of the colloid mill due to too little material in the buffer trough, thereby improving the product quality, improving the production efficiency and reducing the production cost.

[0006] In an optional embodiment, the control mechanism includes a first detection sensor, which is arranged at the bottom of the buffer trough and is communicatively connected to the baffle mechanism for detecting the remaining material in the buffer trough and controlling the baffle mechanism to be in the open position.

[0007] Beneficial effect: By arranging a first detection sensor at the bottom of the buffer tank, when the material in the buffer tank is insufficient, the first detection sensor transmits a signal to the baffle mechanism, the baffle mechanism opens the first discharge port to the open position, and the material in the material tank enters the buffer tank, ensuring that the buffer tank continuously and uninterruptedly transports the material to the colloid mill.

[0008] In an optional embodiment, the first detection sensor is arranged on a side of the buffer tank away from the second discharge port.

[0009] Beneficial effect: by setting the first detection sensor on the side of the buffer trough away from the second discharge port, when the remaining material at the position of the first detection sensor is transported to the second discharge port, the position of the first detection sensor is lacking in material, while there is still some remaining material between the first detection sensor and the second discharge port, and the spiral pushing assembly continues to push the remaining material to the second discharge port into the colloid mill. At this time, the first detection sensor transmits a signal to the baffle mechanism to put the baffle mechanism in the open position, and the material in the material trough enters the buffer trough, so that the material in the buffer trough is replenished in time, ensuring that the material enters the colloid mill continuously and uninterruptedly.

[0010] In an optional implementation, the first detection sensor is a first opposing photoelectric switch.

[0011] Beneficial effect: Since the first photoelectric switch has high resolution and fast response speed, it can be used for object position detection. In actual use, the first photoelectric switch can detect whether there is material in the buffer tank, thereby determining whether the buffer tank needs to be replenished, and transmit the signal to the baffle mechanism.

[0012] In an optional embodiment, the control mechanism also includes a second detection sensor, which is arranged on the side wall of the buffer groove, spaced apart from the bottom of the buffer groove, and communicated with the baffle mechanism to detect the height of the material body in the buffer groove and control the baffle mechanism to be in the closed position.

[0013] Beneficial effect: By setting the second detection sensor apart from the bottom of the buffer trough, it is convenient for the second detection sensor to detect the height of the material in the buffer trough. When it is detected that the material in the buffer trough reaches a certain height, the second detection sensor transmits a signal to the baffle mechanism, and the baffle mechanism closes the first discharge port and is in a closed position. The material trough stops conveying the material into the buffer trough, avoiding blockage caused by excessive material in the buffer trough, ensuring that the spiral pushing assembly can run smoothly, thereby ensuring that the material continuously enters the colloid mill.

[0014] In an optional implementation, the second detection sensor is a second opposing photoelectric switch.

[0015] Beneficial effect: The second photoelectric switch can be used to detect the material body. When the material body reaches a certain height, it can enter the detection range of the photoelectric switch. The second photoelectric switch can sense the material body and trigger the baffle mechanism to be in the closed position by transmitting a signal.

[0016] In an optional embodiment, the control mechanism further includes a reflective lens, which is arranged opposite to the second detection sensor and fixed on the side wall of the buffer groove.

[0017] Beneficial effect: Since the transmitting end of the second detection sensor will emit light and reflect it to the receiving end through the reflective lens, and cooperate with the second detection sensor through the reflective lens, when the material body reaches a certain height, the material body blocks the emission and reception of light between the second detection sensor and the reflective lens. At this time, the second detection sensor will transmit a signal to the baffle mechanism, and the baffle mechanism closes the first discharge port and is in a closed position, and the material trough stops conveying the material body into the buffer trough, thereby realizing the second detection sensor to detect the height of the material body in the buffer trough and realize the signal transmission to the baffle mechanism.

[0018] In an optional embodiment, a spray ball is further included, and the spray ball is arranged on the top of the buffer tank for flushing the buffer tank.

[0019] Beneficial effect: After a batch of materials is processed, the inside of the buffer tank can be cleaned by the spray ball, ensuring the cleanliness of the buffer tank, avoiding contamination of the next batch of materials, and effectively improving the quality of the products produced.

[0020] In an optional embodiment, the spiral pushing assembly includes a driving member and a spiral ring; the driving member includes a driving body and a driving shaft, the driving body is located outside the buffer groove and is fixed on the side wall of the buffer groove opposite to the second discharge port; a connecting hole is provided on the side wall of the buffer groove opposite to the second discharge port, and the driving shaft passes through the connecting hole and extends into the interior of the buffer groove; the spiral ring is arranged on the driving shaft and is spirally arranged with the driving shaft as the center line.

[0021] Beneficial effect: By setting the driving shaft of the driving member inside the buffer groove, the spiral ring is set on the driving shaft and is spirally arranged with the driving shaft as the center line. When the driving body drives the driving shaft to rotate, the spiral ring rotates with the driving shaft, thereby pushing the material body to move toward the second discharge port.

[0022] In an optional embodiment, the driving member is a motor.

[0023] Beneficial effects: The spiral ring is driven to rotate by a motor, which has high reliability. Since the motor does not need regular maintenance, it is more convenient and cost-saving. It can also achieve more precise control to meet the requirements of speed and torque during material transportation, thereby controlling the ratio of material to water entering the colloid mill according to the optimal process requirements, effectively improving product quality.

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0030] Combine the following Figure 1 to Figure 2 , describing an embodiment of the utility model.

[0031] According to an embodiment of the utility model, a material conveying device is provided, including a material trough 1, a baffle mechanism 2, a buffer trough 3 and a control mechanism; a first discharge port 11 is provided at the bottom of the material trough 1; the baffle mechanism 2 is arranged at the position where the first discharge port 11 is located, and has a closed position for closing the first discharge port 11, and an open position for opening the first discharge port 11; the buffer trough 3 is located below the material trough 1, the top is connected to the first discharge port 11, and a second discharge port 31 is provided on one side, and the second discharge port 31 is used to communicate with the top feed port of the colloid mill 4; a spiral pushing assembly 32 is provided in the buffer trough 3, and the spiral pushing assembly 32 is used to continuously push the material to the second discharge port 31; the control mechanism is communicatively connected to the baffle mechanism 2, and is used to detect the material stock in the buffer trough 3, and control the closing and opening of the baffle mechanism 2.

[0032] By adding a buffer tank 3 between the material tank 1 and the colloid mill 4, the material can be continuously and evenly fed into the colloid mill 4, and the ratio of the material to water entering the colloid mill 4 can be controlled according to the optimal process requirements, so that the product quality is effectively improved; compared with the material tank 1 intermittently feeding the colloid mill 4 directly, which causes the colloid mill 4 motor current to run unstable or causes the motor to shut down due to overload, the utility model ensures the stability of the colloid mill 4 motor current, extends the service life of the colloid mill 4, and ensures that the colloid mill 4 can run continuously and stably for a long time, avoiding impact on the power grid; the material stock in the buffer tank 3 is detected by the control mechanism, and the closing and opening of the baffle mechanism 2 are controlled, so as to realize the automatic control of the feeding of the buffer tank 3, which can avoid excessive material storage in the buffer tank 3, and can also avoid too little material in the buffer tank 3 causing feeding interruption of the colloid mill 4, which not only improves the product quality, but also improves the production efficiency and reduces the production cost.

[0033] Specifically, the baffle mechanism 2 includes a baffle and a pneumatic cylinder, and the pneumatic rod is connected to the control mechanism for communication and controls the baffle to be in a closed position or an open position. In actual use, since the buffer tank 3 can store a certain amount of material, the frequency of the pneumatic rod controlling the opening and closing of the baffle can be reduced, the wear of the sealing element of the pneumatic rod itself can be reduced, and the service life of the equipment can be extended.

[0034] Specifically, a discharge pipe is further provided at the second discharge port 31 , one end of the discharge pipe is communicated with the second discharge port 31 , and the other end of the discharge pipe is communicated with the feed port at the top of the colloid mill 4 .

[0035] In one embodiment, the control mechanism includes a first detection sensor 51, which is arranged at the bottom of the buffer tank 3 and is communicated with the baffle mechanism 2 for detecting the remaining material in the buffer tank 3 and controlling the baffle mechanism 2 to be in the open position.

[0036] By setting a first detection sensor 51 at the bottom of the buffer tank 3, when the material in the buffer tank 3 is insufficient, the first detection sensor 51 transmits a signal to the baffle mechanism 2, the baffle mechanism 2 opens the first discharge port 11 to the open position, and the material in the material tank 1 enters the buffer tank 3, ensuring that the buffer tank 3 continuously and uninterruptedly transports the material to the colloid mill 4.

[0037] In one embodiment, the first detection sensor 51 is disposed on a side of the buffer tank 3 away from the second discharge port 31 .

[0038] By arranging the first detection sensor 51 on the side of the buffer trough 3 away from the second discharge port 31, when the remaining material at the position of the first detection sensor 51 is transported to the second discharge port 31, the position of the first detection sensor 51 lacks material, while there is still some remaining material between the first detection sensor 51 and the second discharge port 31, and the spiral pushing component 32 continues to push the remaining material to the second discharge port 31 into the colloid mill 4. At this time, the first detection sensor 51 transmits a signal to the baffle mechanism 2 to put the baffle mechanism 2 in the open position, and the material in the material trough 1 enters the buffer trough 3, so that the material in the buffer trough 3 is replenished in time, ensuring that the material enters the colloid mill 4 continuously and uninterruptedly.

[0039] In one embodiment, the first detection sensor 51 is a first photoelectric switch.

[0040] Since the first photoelectric switch has high resolution and fast response speed, it can be used for object position detection. In actual use, the first photoelectric switch can detect whether there is material in the buffer tank 3, thereby determining whether the buffer tank 3 needs to be replenished with material, and transmit the signal to the baffle mechanism 2.

[0041] As an alternative implementation, the first detection sensor 51 may also be a radar sensor, an ultrasonic sensor, an image sensor, etc.

[0042] In one embodiment, the control mechanism also includes a second detection sensor 52, which is arranged on the side wall of the buffer groove 3, spaced apart from the bottom of the buffer groove 3, and communicated with the baffle mechanism 2, for detecting the height of the material body in the buffer groove 3 and controlling the baffle mechanism 2 to be in the closed position.

[0043] By setting the second detection sensor 52 apart from the bottom of the buffer trough 3, it is convenient for the second detection sensor 52 to detect the height of the material in the buffer trough 3. When it is detected that the material in the buffer trough 3 reaches a certain height, the second detection sensor 52 transmits a signal to the baffle mechanism 2, and the baffle mechanism 2 closes the first discharge port 11 in a closed position, and the material trough 1 stops conveying the material into the buffer trough 3, avoiding blockage caused by excessive material in the buffer trough 3, ensuring that the spiral pushing assembly 32 can run smoothly, thereby ensuring that the material continuously enters the colloid mill 4.

[0044] In one embodiment, the second detection sensor 52 is a second photoelectric switch.

[0045] The second photoelectric switch can be used to detect the material body. When the material body reaches a certain height, it can enter the detection range of the photoelectric switch. The second photoelectric switch can sense the material body and trigger the baffle mechanism 2 to be in the closed position by transmitting a signal.

[0046] As an alternative implementation, the second detection sensor 52 may also be a radar sensor, an ultrasonic sensor, an image sensor, etc.

[0047] In one embodiment, the control mechanism further includes a reflective lens 53 , which is disposed opposite to the second detection sensor 52 and fixed on a side wall of the buffer tank 3 .

[0048] Since the transmitting end of the second detection sensor 52 will emit light which is reflected to the receiving end via the reflective lens 53, and through the cooperation between the reflective lens 53 and the second detection sensor 52, when the material body reaches a certain height, the material body blocks the emission and reception of light between the second detection sensor 52 and the reflective lens 53. At this time, the second detection sensor 52 will transmit a signal to the baffle mechanism 2, and the baffle mechanism 2 closes the first discharge port 11 and is in a closed position, and the material trough 1 stops conveying the material body into the buffer trough 3, thereby realizing the second detection sensor 52 to detect the height of the material body in the buffer trough 3 and realize the signal transmission to the baffle mechanism 2.

[0049] Preferably, the second detection sensor 52 and the reflective lens 53 are located on the same straight line, and the straight line where the second detection sensor 52 and the reflective lens 53 are located is offset from the first discharge port 11 .

[0050] In one embodiment, a spray ball 6 is further included. The spray ball 6 is arranged on the top of the buffer tank 3 and is used to flush the buffer tank 3.

[0051] After a batch of materials is processed, the inside of the buffer tank 3 can be cleaned by the spray ball 6, thereby ensuring the cleanliness of the buffer tank 3, avoiding contamination of the next batch of materials, and effectively improving the quality of the produced products.

[0052] In a specific implementation, the spray ball 6 is connected to the flushing pipe 7 . After each batch of material is processed, the valve of the flushing pipe 7 is opened to achieve all-round cleaning of the buffer tank 3 through the spray ball 6 .

[0053] In one embodiment, the spiral pushing assembly 32 includes a driving member and a spiral ring 322; the driving member includes a driving body 3211 and a driving shaft 3212, the driving body 3211 is located outside the buffer groove 3, and is fixed on the side wall of the buffer groove 3 opposite to the second discharge port 31; a connecting hole is provided on the side wall of the buffer groove 3 opposite to the second discharge port 31, and the driving shaft 3212 passes through the connecting hole and extends into the interior of the buffer groove 3; the spiral ring 322 is sleeved on the driving shaft 3212, and is spirally arranged with the driving shaft 3212 as the center line.

[0054] By setting the driving shaft 3212 of the driving member inside the buffer groove 3, the spiral ring 322 is sleeved on the driving shaft 3212 and is spirally arranged with the driving shaft 3212 as the center line. When the driving body 3211 drives the driving shaft 3212 to rotate, the spiral ring 322 rotates with the driving shaft 3212, thereby pushing the material body to move toward the second discharge port 31.

[0055] In a specific embodiment, the driving shaft 3212 is perpendicular to the side wall of the buffer tank 3 where the second discharge port 31 is located; and one end of the driving shaft 3212 is located at the connecting hole and is drivingly connected to the driving body 3211, and the other end extends to the position where the second discharge port 31 is located.

[0056] Specifically, the length of the center line of the spiral coil 322 is the same as that of the driving shaft 3212 .

[0057] In one embodiment, the driving member is a motor.

[0058] The spiral ring 322 is driven to rotate by a motor, which has high reliability. Since the motor does not need regular maintenance, it is more convenient and cost-saving. It can also achieve more precise control to meet the requirements of speed and torque during material transportation, thereby controlling the ratio of material and water entering the colloid mill 4 according to the optimal process requirements, thereby effectively improving product quality.

[0059] In a specific embodiment, an automatic feeder is fixedly connected to the top of the material trough 1, and the automatic feeder is provided with a feed suction pipe. The automatic feeder sucks the soaked material through the feed suction pipe. After a certain amount of material is stored in the automatic feeder, it automatically falls into the material trough 1 under the action of gravity and is stored in the material trough 1. When the first detection sensor 51 detects that there is a lack of material in the buffer trough 3, the first detection sensor 51 of the baffle mechanism 2 transmits a signal to the baffle mechanism 2, the baffle mechanism 2 opens the first discharge port 11 and is in the open position, and the material in the trough 1 enters the buffer trough 3; when the second detection sensor 52 detects that the material in the buffer trough 3 reaches a certain height, the second detection sensor 52 transmits a signal to the baffle mechanism 2, the baffle mechanism 2 closes the first discharge port 11 and is in the closed position, and the trough 1 stops conveying the material into the buffer trough 3. During this process, the driving shaft 3212 of the motor always drives the spiral ring 322 to operate, pushing the material in the buffer trough 3 into the colloid mill 4, and the colloid mill 4 grinds and refines the material. During the grinding and refining process, water is continuously added to the colloid mill 4 through the water inlet pipe, so that the ground material enters the next process in the state of slurry for more refined grinding. It can ensure that the material enters the colloid mill 4 continuously and evenly, and the entire process of the material falling and being transported to the colloid mill 4 for grinding and refinement is controlled by an automated program, without the need for direct operation by on-site personnel, thereby reducing the labor intensity of the operators.
