[0029] In order to describe the present utility model in detail, a belt feeder of the present utility model will be specifically described below:

[0030] Please refer to Figures 1 to 4 As shown, the present utility model provides a belt feeder, which includes a feeder body, two rotating members, and an endless conveyor belt 5. The two rotating members are arranged at intervals on the feeder body; the endless conveyor belt 5 is arranged on the two rotating members. The two rotating members are used to tension and drive the endless conveyor belt 5 to move. The endless conveyor belt 5 has opposite inner and outer sides. The rotating members are arranged on the inner side of the endless conveyor belt 5, and the outer side of the endless conveyor belt 5 is used to carry materials; wherein, the rotating members each have a rotating shaft, and a first limiting structure is arranged on at least one rotating member. The first limiting structure is arranged around the rotating shaft for one week. A second limiting structure corresponding to the first limiting structure is arranged on the inner side of the endless conveyor belt 5. The second limiting structure extends along the conveying direction of the endless conveyor belt 5. The first limiting structure and the second limiting structure cooperate to limit the relative position between the endless conveyor belt 5 and the rotating members in the width direction of the endless conveyor belt 5. It should be noted that the width direction of the endless conveyor belt 5 is perpendicular to the conveying direction of the endless conveyor belt 5, and the conveying direction is the direction in which the endless conveyor belt 5 conveys materials.

[0031] Thus, by arranging the first limiting structure on the inner side of the endless conveyor belt 5 and the second limiting structure on the rotating members, the first limiting structure and the second limiting structure cooperate to prevent the endless conveyor belt 5 from slipping relative to the rotating members in the width direction of the endless conveyor belt 5, resulting in an increase in wear after the endless conveyor belt runs off track. Since the belt feeder is provided with the first limiting structure and the second limiting structure, the stability of the endless conveyor belt during the process of conveying materials can be ensured, the production efficiency is improved, and there is no need to invest manpower for monitoring, thus liberating the labor force.

[0032] In this embodiment, the rotating members are driving rollers 2. The two driving rollers 2 are arranged side by side at intervals. The two driving rollers 2 rotate along the axial direction of the driving rollers 2 to drive the endless conveyor belt 5 to move so as to transport materials. In some embodiments, the rotating member can be a driving wheel, or one rotating member can include multiple driving wheels, and the multiple driving wheels are arranged in sequence along the axial direction of the driving wheels. The type of the rotating member can be adjusted according to actual needs.

[0033] Among them, the rotating member is the transmission roller 2, the first limiting structure is a limiting groove formed in the circumferential direction of the transmission roller 2, the limiting groove surrounds the axis of the transmission roller 2 for one week, the second limiting structure is a limiting protrusion protruding towards the rotating member in the thickness direction of the annular conveyor belt 5, the limiting protrusion extends along the conveying direction of the annular conveyor belt 5 and forms a ring; or, the first limiting structure is a limiting protrusion 4 protruding in the radial direction of the transmission roller 2, the limiting protrusion surrounds the axis of the transmission roller 2 for one week and forms a ring, the second limiting structure is a limiting groove 3 formed in the annular conveyor belt 5, the limiting groove 3 extends along the conveying direction of the annular conveyor belt 5, and at least part of the limiting protrusion is accommodated in the limiting groove 3. It should be noted that the thickness direction of the annular transmission belt 5 is perpendicular to the width direction of the annular conveyor belt 5. The limiting protrusion 4 and the limiting groove 3 limit the annular conveyor belt 5 in the width direction of the annular conveyor belt 5, and the structure is simple and easy to produce and manufacture. In some embodiments, the first limiting structure is a first blocking strip, the first blocking strip extends along the conveying direction of the annular conveyor belt 5 to form a ring, the second limiting structure is a second blocking strip arranged corresponding to the blocking strip, and the second limiting structure is arranged along the circumferential direction of the transmission roller 2 to form a ring. At least two first limiting structures and second limiting structures are arranged on the annular conveyor belt 5 to limit in the width direction of the annular conveyor belt 5.

[0034] In this embodiment, the second limiting structure is arranged on both transmission rollers 2, so that the limiting effect on the annular transmission belt 5 can be enhanced. The first limiting structure is a limiting protrusion 4 protruding in the radial direction of the transmission roller 2, the limiting protrusion surrounds the axis of the transmission roller 2 for one week and forms a ring, the second limiting structure is a limiting groove 3 formed in the annular conveyor belt 5, the limiting groove 3 extends along the conveying direction of the annular conveyor belt 5, and the limiting protrusion 4 at the contact position between the transmission roller 2 and the annular conveyor belt 5 is completely accommodated in the limiting groove 3. The annular conveyor belt 5 can be a rubber conveyor belt convenient for forming the limiting groove 3, and the type of the conveyor belt 5 can be adjusted according to actual needs.

[0035] As Figure 4 shown, among them, the length of the cross-section of the limiting protrusion away from the axis of the transmission roller 2 is less than the length of the cross-section close to the axis of the transmission roller 2, and the cross-section of the limiting groove 3 is arranged corresponding to the cross-section of the limiting protrusion 4. Such a setting can avoid generating a large lateral shear force when the limiting protrusion 4 moves in the limiting groove 3. If the lateral shear force is too large, it will cause the edge of the limiting protrusion 4 to fluff, resulting in the failure of the limit, and even damage the transmission roller 2 or the annular conveyor belt 5, affecting the conveying of materials and causing economic losses.

[0036] Specifically, the cross-section of the limit projection 4 is an isosceles trapezoid, with the lower base of the isosceles trapezoid close to the driving roller 2 and the upper base of the isosceles trapezoid away from the driving roller 2. The cross-section of the limit projection 4 being an isosceles trapezoid facilitates production and assembly. At the same time, since the lengths and angles of the two sides of the isosceles trapezoid are the same, the two sides of the isosceles trapezoid of the limit projection 4 can more evenly share the lateral shearing force of the endless conveyor belt 5, improving the stability of the width-direction limit of the endless conveyor belt 5 and achieving a good limiting effect.

[0037] In some embodiments, one limit projection 4 includes a plurality of limit teeth, and the plurality of limit teeth are arranged at intervals in sequence along the conveying direction of the endless conveyor belt 5. This setting can save the raw material cost during the manufacture of the limit projection. At the same time, when the limit projection is provided on the endless conveyor belt 5, the plurality of limit teeth arranged at intervals can increase the bendability of the endless conveyor belt 5, avoiding the situation where the limit projection on the endless conveyor belt 5 slips out of the limit groove due to bending and improving the operating stability of the belt feeder. In other embodiments, the bottom of the limit groove 3 may be provided with a plurality of limit cross bars extending along the width direction of the limit groove 3 corresponding to the limit teeth. The plurality of limit cross bars are arranged at intervals in sequence along the conveying direction of the endless conveyor belt 5 at the bottom of the limit groove 3, and one limit tooth can be accommodated between two limit cross bars to prevent the endless conveyor belt 5 from slipping during movement.

[0038] Among them, at least two second limiting structures are provided on each rotating member, and the first limiting structure of the endless conveyor belt is arranged corresponding to the second limiting structure. Providing at least two first limiting structures and second limiting structures can increase the stability of the limit. In this embodiment, two first limiting structures and two second limiting structures corresponding to the first limiting structures are provided on one driving roller 2. The number of second limiting structures provided on the rotating member can be adjusted according to the specific types of the first limiting structure and the second limiting structure and specific production requirements.

[0039] As Figure 3 shown, among them, the driving roller 2 is arranged inside the endless conveyor belt 5, and a placement position for placing materials is provided on the outside of the endless conveyor belt 5, and a lining plate group 6 is provided on the placement position. By providing the lining plate group 6 on the placement position, the endless conveyor belt 5 can be prevented from being worn during material transportation, the wear amount of the endless conveyor belt 5 can be reduced, the maintenance and replacement cost of the endless conveyor belt 5 can be reduced, and it has good economy.

[0040] Specifically, the lining plate group 6 includes a plurality of lining plates, and the plurality of lining plates are connected to each other and cover the placement position. Lining plates are provided on all placement positions, which can protect the conveyor belt 5 from wear to the greatest extent.

[0041] Among them, the belt feeder further includes a power device 1, which is arranged on the feeder body and connected to the transmission roller 2. The power device 1 is used to drive the transmission roller 2 to rotate. In this embodiment, one of the two transmission rollers 2 is a driving roller and the other is a driven roller. The driving roller is connected to the power device 1. The power device 1 drives the driving roller to rotate, the driving roller rotates to drive the conveyor belt 5 to move, and the conveyor belt 5 moves to drive the driven roller to rotate, so as to realize automatic control of the belt feeder to transport materials. In this embodiment, the power device 1 is a motor. The motor has the advantages of high energy efficiency, environmental protection, low noise, low maintenance cost, high control accuracy and fast response. The type of the power device 1 can be adjusted according to actual needs.

[0042] In summary, by arranging the first limiting structure on the inner side of the annular conveyor belt 5 and the second limiting structure on the rotating part, the first limiting structure and the second limiting structure cooperate to prevent the annular conveyor belt 5 from slipping relative to the rotating part in the width direction of the annular conveyor belt 5, resulting in an increase in wear after the annular conveyor belt runs off track. Since the first limiting structure and the second limiting structure are provided on the belt feeder, the stability of the annular conveyor during the material conveying process can be ensured, the production efficiency can be improved, and there is no need to invest manpower for monitoring, thus liberating the labor force.
