Description

Technical Field

[0001] The utility model relates to a material dividing device, belonging to the technical field of automation equipment. Background Art

[0002] The material distributor is mainly used to distribute materials to different production lines or processing stations accurately according to the predetermined procedures and quantities. In modern production, the efficiency and accuracy of the material distributor directly affect the smoothness of the entire production process and the quality of the final product.

[0039] See also Figures 1 to 3The material dispensing device 100 shown in a preferred embodiment of the present application includes a base 1, a feeding mechanism (not numbered) and a receiving mechanism 4. The feeding mechanism includes a conveying assembly 2 disposed on the base 1 and a feeding assembly 3 disposed on the conveying assembly 2. The feeding assembly 3 moves along a first direction on the conveying assembly 2 between a first position and a second position.

[0040] The base 1 is the structural foundation of the conveying assembly 2, the feeding assembly 3 and the receiving mechanism 4, and serves as a supporting platform for installing the conveying assembly 2, the feeding assembly 3 and the receiving mechanism 4.

In other embodiments, the first sub-frame 321 and the second sub-frame 322 can both be relatively slidably arranged on the bottom plate 31, and it is only necessary to ensure that the width between the first sub-frame 321 and the second sub-frame 322 can be adjusted.

The first width adjusting motor 34 drives the second sub-frame 322 to move along the first direction on the base plate 31, thereby realizing the adjustment of the width between the first sub-frame 321 and the second sub-frame 322.

[0044] In another embodiment, the first width adjustment motor 34 may not be provided, and the widths of the first sub-frame 321 and the second sub-frame 322 may be adjusted manually.

[0045] In one embodiment, a limiting mechanism 311 is further provided on the bottom plate 31, and the limiting mechanism 311 is located at one end of the feeding assembly 3 close to the receiving assembly 4. The limiting mechanism 311 includes a limiting cylinder 3111 fixed on the bottom plate 31 and a limiting block 3112 installed on the output shaft of the limiting cylinder 3111, and the limiting block 3112 can protrude from the horizontal plane where the first transmission unit 33 is located under the drive of the limiting cylinder 3111. The material moves along the second direction on the first frame 32 under the drive of the first transmission unit 33, and at this time, the limiting block 3112 rises upward, so that the material contacts the limiting block 3112, thereby limiting the material in the second direction to prevent the material from moving out of the first frame 32, wherein the second direction is perpendicular to the first direction on the horizontal plane.

The first transmission wheel group is located inside the first frame 32, and includes two first driven wheels 3322 installed on the first frame 32 along the second direction and a first driving wheel 3321 installed between the two first driven wheels 3322, wherein the driving wheel 3321 is arranged on the output shaft of the first transmission motor 332, and the two first driven wheels 3322 are arranged horizontally on both sides of the first driving wheel 3321 along the second direction. The first transmission belt 333 is tensioned on the first transmission wheel group. When the first transmission motor 331 is started, the output shaft of the first transmission motor 331 rotates, driving the first driving wheel 3321 to rotate, and with the cooperation of the first driven wheel 3322, the first transmission belt 333 can rotate along the second direction.

[0049] In one embodiment, first tensioning wheels 334 are further disposed on both sides of the first driving wheel 3321 for tensioning the first transmission belt 333 to reduce vibration and prevent slipping.

[0050] In this embodiment, the conveying assembly 2 includes a driving motor 21, a slide rail 22, a transmission unit 23 and a connecting block (not shown). The driving motor 21 is fixed on the base 1 to provide power so that the feeding assembly 3 can move along the first direction. The slide rails 22 are two relatively arranged, and the two slide rails 22 extend along the first direction. The bottom plate 31 is slidably arranged on the slide rails 22. The slide rails 22 are used to provide auxiliary support for the feeding assembly 3 so that the feeding assembly 3 moves more smoothly along the first direction. The transmission unit 23 includes a driving wheel 231 and a driven wheel 232 arranged between the two slide rails 22, and a synchronous belt 233 tensioned on the driving wheel 231 and the driven wheel 232. In the first direction, the driving wheel 231 and the driven wheel 232 are respectively located at the two ends of the slide rail 22. The output shaft of the driving motor 21 is connected to the driving wheel 231, the connecting block is meshed with the synchronous belt 233, and the bottom plate 31 is fixed on the connecting block. The driving motor 21 is started, driving the active wheel 231 to rotate, and the active wheel 231 and the driven wheel 232 cooperate to make the synchronous belt 233 rotate along the first direction, and then drive the connecting block to move along the first direction, thereby making the bottom plate 31 move together, so that the conveying component 2 drives the feeding component 3 to move between the first position and the second position along the first direction.

[0051] In another embodiment, the conveying assembly 3 may also be a linear motor or a cylinder. When the conveying assembly 3 is a linear motor, the bottom plate 31 is disposed on the linear motor, and the linear motor directly drives the conveying assembly to move along the first direction. When the conveying assembly 3 is a cylinder, the bottom plate 31 is disposed on the output shaft of the cylinder, and the cylinder can directly drive the bottom plate to move along the first direction.

[0052] The receiving mechanisms 4 are two groups arranged side by side on one side of the conveying component 2. When the feeding component 3 is in the first position, the feeding component 3 is aligned with one group of the receiving mechanisms 4 in the second direction. When the feeding component 3 is in the second position, the feeding component is aligned with the other group of the receiving mechanisms 4 in the second direction, so that the material can be transported to different receiving mechanisms 4.

[0053] Each set of receiving mechanisms 4 includes two second frames 41 relatively arranged on the base 1, and a second transmission unit 42 arranged on the second frames 41. At least one of the two second frames 41 is slidably arranged on the base 1 and can be moved along the first direction. By changing the distance between the two second frames 41, the width of the receiving structure 4 can be adjusted to adapt to materials of different sizes.

[0054] In this embodiment, the receiving mechanism 4 also includes a slide plate 43 arranged above the base 1 and a guide rail assembly 44 installed between the slide plate 43 and the base 1, and the slide plate 43 is slidably arranged on the guide rail assembly 44, so that the receiving mechanism 4 can be conveniently moved to a specified position along the first direction, and can be aligned with the feeding assembly along the second direction. Each group of second frames 41 includes a third sub-frame 411 and a fourth sub-frame 412 installed on the slide plate 43, and the fourth sub-frames 412 in the two groups are arranged adjacently, and the fourth sub-frame 412 is slidably arranged on the slide plate 43 along the first direction. Specifically, the receiving mechanism 4 also includes a second width adjustment motor 45, the second width adjustment motor 45 is arranged on a side of the third sub-frame 411 away from the fourth sub-frame 412, the output shaft of the second width adjustment motor 45 is connected to the third sub-frame 411, and the second width adjustment motor 45 drives the fourth sub-frame 412 to move along the first direction on the slide plate 43, thereby adjusting the distance between the third sub-frame 411 and the fourth sub-frame 412. Similarly, in other embodiments, the second width-adjusting motor 45 may not be provided, and the distance between the third sub-frame 411 and the fourth sub-frame 412 may be adjusted manually.

[0055] The second transmission unit 42 includes a second transmission motor 421 , a second transmission wheel set (not numbered), and a second transmission belt 423 .

[0056] Conventionally, the second transmission motor 421, the second transmission wheel set and the second transmission belt 423 are two groups, which are respectively arranged on the third sub-frame 411 and the fourth sub-frame 412. The second transmission motor 421 of each group drives the second transmission belt 423 in the same group to rotate only through the second transmission wheel set in the same group. However, in such an arrangement, the second transmission motors 421 arranged on the adjacent fourth sub-frames 412 of the two groups of receiving mechanisms 4 may interfere with each other during the width adjustment process.

[0057] In order to solve the above problem, one second transmission motor 421 is provided in each receiving mechanism 4, and two second transmission wheel groups are provided. Specifically, the second transmission motor 421 is provided on the side of the third sub-frame 411 away from the fourth sub-frame 412, and the output shaft of the second transmission motor 421 passes through the third sub-frame 411 and the fourth sub-frame 412, and a bearing is provided between the output shaft of the second transmission motor 421 and the third sub-frame 411 and the fourth sub-frame 412. At this time, the second transmission motor 421 is not installed on the fourth sub-frame 412, so there will be no interference during the width adjustment process.

[0058] The second transmission wheel groups are two groups respectively arranged on the second frame 41, and each group of the second transmission wheel groups is located on the inner side of the corresponding second frame 41, that is, a group of second transmission wheel groups is arranged on the inner side of the third sub-frame 411 and the second sub-frame 412. Each group of the second transmission wheel groups includes two second driven wheels 4222 installed on the second frame 41 along the second direction and a second driving wheel 4221 installed between the two second driven wheels 4222, wherein the second driving wheels 4221 are all installed on the output shaft of the second transmission motor 421, and the second driven wheels 4222 are arranged on both sides of the second driving wheels 4221 of the same group along the second direction.

[0059] The second transmission belts 423 are two groups respectively arranged on the second frame 41, and each group of the second transmission belts 423 is stretched on the second transmission wheel group. The second transmission motor 421 is started, and the output shaft of the second transmission motor 421 rotates, and at the same time drives the two groups of second driving wheels 4221 to rotate, and with the cooperation of the second driven wheels 4222 of the same group, the second transmission belts 423 of the same group can rotate along the second direction.

[0060] In one embodiment, second tensioning wheels 424 are further disposed on both sides of the second driving wheel 4221 for tensioning the second transmission belt 423 to reduce vibration and prevent slipping.

[0061] The working process of the material distribution device 100 is as follows: First, other devices transmit signals of the current material size. According to the signals, the first width adjustment motor 34 drives the two first frames 32 to move relative to each other to adjust the distance between the two first frames 32. The second width adjustment motor 45 drives the two second frames 41 of the same group to move relative to each other to adjust the distance between the two second frames 41 of the same group, so that the width of the feeding component 3 and the receiving mechanism 4 is adapted to the width of the material. Then, the material is transported to the feeding component by the upper device, and the material is located at the designated position on the feeding component 3 by the limit mechanism 311 under the drive of the first transmission unit 33. Then, according to the material information, under the drive of the conveying component 2, the feeding component 3 is moved to the first position or the second position, the limit mechanism 311 returns to its position, and the first transmission unit 33 drives the material to enter the receiving mechanism 4. Finally, under the drive of the second transmission unit 42, the material enters the lower device and a new round of material distribution is started again.

[0062] Since the first frame 32 of the feeding component 3 and the second frame 41 of the receiving mechanism 4 of the material dividing device 100 are both slidably arranged, the width of the feeding component 3 and the receiving mechanism 4 can be changed according to the size of the material to be transported, that is, the material dividing device 100 can adapt to the classification of materials of different sizes, effectively solving the limitations of traditional equipment in processing materials of different sizes, and greatly improving the flexibility and efficiency of the production line.

[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
