Description

Technical Field

[0001] The utility model relates to a belt conveyor device, in particular to a spreading mechanism of a belt conveyor device. Background Art

[0002] In food processing, a belt conveyor device is a commonly used conveyor device. The belt is used to place materials, and at the same time, relying on the movement of the belt, the materials are driven to be linearly conveyed. In food processing, granular or powdery materials are commonly used, and these are generally also conveyed to the corresponding processing stations through a belt conveyor device. For such granular or powdery materials, it is generally necessary to spread them out flat on the conveyor belt to facilitate observing defective particles and also to make the materials evenly distributed on the conveyor belt. Currently, generally a scraper is used. The materials fall on the middle position of the belt and accumulate. When passing through the scraper, they are spread out to both sides under the action of the scraper. There are still problems: the width of the belt is relatively large, and when the materials fall, they are relatively concentrated in the middle position of the belt. Only relying on the scraper, the degree of spreading to both sides is limited and not uniform enough. Summary of the Utility Model

[0003] This application provides a spreading mechanism of a belt conveyor device, which can solve the problems raised in the background art.

[0004] In this application, a spreading mechanism of a belt conveyor device is provided, including:

[0005] An installation part for installing to the equipment frame of the belt conveyor device;

[0006] A material bin fixed to the installation part, having a feed inlet with a communicating inner cavity, and the bottom surface is open;

[0007] A discharge part, including: a material blocking part and a discharge port, and the discharge port can be switched between opening and closing; the discharge part slides horizontally along a first direction on the bottom surface opening of the material bin, so that the raw materials in the material bin can only fall from the discharge port of the discharge part;

[0008] A driving part is arranged in the material bin to drive the discharge part to slide back and forth;

[0009] A scraper is fixed to the installation part.

[0010] Further, the material bin includes: two first plates, four belt pulleys respectively rotatably arranged at the four corner positions of the two first plates, and two second plates fixed between the two first plates; the four belt pulleys are outside the inner cavity surrounded by the two second plates and the two first plates; the feed inlet is arranged on one of the first plates; the material blocking part is a first belt arranged on the four belt pulleys.

[0011] Further, during the process of the discharging part sliding from one side to the other side along the first direction, when it is limited at both sides, the discharging port extends beyond the inner cavity of the silo.

[0012] Further, the driving part is a lead screw module, and the discharging port is fixed to the mounting slider of the lead screw module.

[0013] Further, the first belt is disconnected, and the two broken ends are respectively fixed to both sides of the discharging port.

[0014] Further, the scraper can adjust its fixed position on the mounting part along the up and down direction.

[0015] In summary, in this application, a spreading mechanism with a belt conveyor includes a mounting part, a silo, a discharging part, a driving part, and a scraper. When the belt of the belt conveyor pauses transmission, the driving part drives the discharging part to slide from one side to the other side. During this process, the discharging port is opened, and the material in the silo forms a strip on the belt along the first direction (i.e., the width direction of the belt); then the belt of the belt conveyor transmits for a certain distance and then pauses again (i.e., the belt moves intermittently), and the driving part drives the discharging part to return. During this process, the discharging port is opened, and the material in the silo also forms a strip on the belt along the first direction; and so on in a cycle. As the belt transmits, this strip of material passes through the scraper and is further spread and flattened by the scraper. The beneficial effects are as follows: The effect of spreading the material on the belt is better and more uniform. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Please refer to Figure 1 and Figure 2 , a spreading mechanism with a conveying device, including a mounting part 1, a silo 2, a discharging part 3, a driving part 4 and a scraper 5.

[0030] The mounting part 1 is used to mount the silo 2 and the scraper 5, and the discharging part 3 and the driving part 4 are arranged on the silo 2. The entire spreading mechanism is mounted on the equipment frame of the belt conveying device through the mounting part 1. Of course, the equipment frame of the belt conveying device can also be used as the mounting part 1, and the silo 2 and the scraper 5 can be directly mounted on the equipment frame of the belt conveying device.

[0031] The silo 2 is fixedly connected to the mounting part 1. Specifically, L-shaped connecting feet 2d can be fixedly connected to both sides of the silo 2, and the connecting feet 2d are then fixedly connected to the mounting part 1. The silo 2 is provided with a feeding port 2e through which materials enter the inner cavity 2f of the silo 2. The bottom surface of the silo 2 is open.

[0032] Please refer to Figure 3 and Figure 4, the discharging part 3 includes a material blocking part 3a and a discharging port 3b, and the discharging port 3b can be switched between an open state and a closed state. The discharging part 3 also slides horizontally along a first direction on the bottom opening of the bin 2, and the first direction is the direction between the two connecting feet 2d. Corresponding to the belt conveyor, the first direction is perpendicular to the conveying direction of the belt on the belt conveyor. The discharging part 3 enables the raw materials in the bin 2 to only fall from the discharging port 3b of the discharging part 3, that is, the material blocking part 3a is used to block the corresponding position of the bottom opening of the bin 2.

[0033] In this way, when the belt of the belt conveyor pauses conveying, the discharging part 3 slides from one side to the other side along the first direction. During this process, the discharging port 3b is opened, and the materials in the bin 2 form a strip on the belt along the first direction (i.e., the width direction of the belt).

[0034] In some embodiments, the material blocking part 3a can be a baffle, and the discharging port 3b is arranged on the baffle. With such a setting, the baffle needs to be relatively long. During the process that the discharging part 3 slides from one side to the other side along the first direction, at least one end of the two ends of the baffle penetrates out of the bin 2.

[0035] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , in some embodiments, the material blocking part 3a can be a belt (marked as the first belt). The corresponding settings are as follows:

[0036] The bin 2 includes two first plates 2a, four belt pulleys 2b, and two second plates 2c;

[0037] The two second plates 2c are fixedly arranged between the two first plates 2a. Specifically, a first screw can be used to fixedly connect the two. After the two second plates 2c and the two first plates 2a are installed, an inner cavity 2f is formed. The feeding port 2e communicates with the inner cavity 2f and is arranged on one of the first plates 2a; correspondingly, the two first plates 2a are in an L shape, and the bent part is used for connecting the connecting feet 2d;

[0038] The four belt pulleys 2b are respectively rotatably arranged at the four corner positions of the two first plates 2a; specifically, both ends of the belt pulley 2b can be integrally provided with shaft ends, and the four corner positions of the first plates 2a are all provided with holes for inserting the shaft ends. When the two second plates 2c and the two first plates 2a are installed, the four belt pulleys 2b are also placed at the corresponding positions to complete rotation; the four belt pulleys 2b are outside the inner cavity 2f formed by the two second plates 2c and the two first plates 2a, that is, the four belt pulleys 2b will not contact the materials entering the bin 2.

[0039] The material blocking part 3a is arranged on the four belt pulleys 2b, that is, the first belt serves as the material blocking part 3a and is tensioned on the four belt pulleys 2b. Additionally, a material guiding part 2a1 can be provided at the lower position of the inner walls of the two first plates 2a. The material guiding part 2a1 is located between the two second plates 2c and above the first belt, preventing the material entering the inner cavity 2f of the bin 2 from getting stuck in the gap between the two sides of the first belt and the two first plates 2a.

[0040] Compared with the case where "the material blocking part 3a can be a baffle", in this way, during the process of the discharging part 3 sliding from one side to the other along the first direction, neither side of the first belt needs to pass through the bin 2.

[0041] Please refer to Figure 4 , furthermore, the first belt is disconnected, and the two broken ends are respectively fixedly connected to the two sides of the discharge port 3b. Specifically, the discharge port 3b can be arranged on a connecting block 3c, and the two broken ends of the first belt are both fixedly connected to the two vertical outer walls of the connecting block 3c through toothed pressing plates 3c1.

[0042] In this way, on the one hand, it is simpler and more convenient to install the first belt onto the four belt pulleys 2b or remove it from the four belt pulleys 2b. On the other hand, by loosening one of the toothed pressing plates 3c1, one of the broken ends of the first belt can be pulled, and it is very convenient to adjust the first belt. After keeping it taut, the toothed pressing plate 3c1 is tightened again.

[0043] In some embodiments, the discharge port 3b can be switched between open and closed, which can be: installing a control solenoid valve on the discharge port 3b.

[0044] Please refer to Figure 3 , in some embodiments, the discharge port 3b can be switched between open and closed, and it can also be: during the process of the discharging part 3 sliding from one side to the other along the first direction, when it is at the two-side limits, the discharge port 3b extends beyond the inner cavity 2f of the bin 2, that is, when the discharge port 3b extends beyond the inner cavity 2f, the discharge port 3b is equivalent to being closed; when the discharge port 3b corresponds to the inner cavity 2f, the discharge port 3b is equivalent to being open.

[0045] Compared with using a solenoid valve, in this way, the structure is simpler and more convenient to control.

[0046] Combined with the above setting that "the material blocking part 3a can be a belt", that is, the positions of the two second plates 2c and the two-side limits of the discharging part 3 need to be set so that when the discharging part 3 is at the two-side limits, the discharge port 3b extends beyond the corresponding second plate 2c.

[0047] Please refer to Figure 2 and Figure 5 , the driving part 4 is arranged on the bin 2 to drive the discharging part 3 to slide back and forth.

[0048] In some embodiments, the driving part 4 is a lead screw module, and the discharging part 3 is fixed to the mounting slider 4a of the lead screw module. Specifically, a connecting piece 4a1 can be used to fixedly connect the discharging part 3 and the mounting slider 4a. In combination with the above setting that "the baffle part 3a can be a belt", the connecting piece 4a1 is fixedly connected to the connecting block 3c.

[0049] In this way, when the belt of the belt conveyor pauses, the lead screw of the lead screw module rotates to drive the discharging part 3 to slide from one side to the other side; then after the belt of the belt conveyor conveys for a period and then pauses (i.e., the belt moves intermittently), the lead screw of the lead screw module rotates in the reverse direction to drive the discharging part 3 to return; and so on in a cycle.

[0050] The scraper 5 is fixedly connected to the mounting part 1. Specifically, the fixed position of the scraper 5 is set according to the conveying direction of the belt on the belt conveyor. The material first falls from the feed bin 2 onto the belt, and under the action of the discharging part 3, the material can form a strip on the belt along the width direction of the belt. As the subsequent belt conveys, this strip of material passes through the scraper 5 and is further spread out and flattened by the scraper 5.

[0051] Please refer to Figure 1 , in some embodiments, the scraper 5 can adjust its fixed position on the mounting part 1 in the up-down direction. Specifically, two waist-shaped through slots 5a can be provided on the scraper 5, and the screws pass through the waist-shaped through slots 5a and are threadedly connected to the mounting part 1.
