Description

Technical Field

[0001] The utility model relates to the technical field of roller bearing processing, in particular to a blank material recycling device. Background Technique

[0002] The cylindrical roller blank is an important part for producing cylindrical roller bearings, usually made of cylindrical metal bar stock or pipe materials. The processing of the cylindrical blank is relatively less difficult and the processing process is simple. During the production process, in order to improve the production efficiency of the cylindrical roller blanks, blanks of various sizes are generally produced simultaneously, and then sorted during the recycling and blanking process.

[0003] For the use of a sorting and recycling device for mixed blank materials containing two sizes, generally, the raw materials are placed inside an oscillating screen. The non-conforming sizes directly fall through the mesh screen, and the oscillating screen is tilted to a certain extent to convey the parts that meet the requirements on the surface. However, the blank materials falling onto the oscillating screen mostly fall concentratedly. To reduce the mutual wear between the blank materials, it is necessary to control the feeding quantity of the blank materials. Usually, workers feed the oscillating screen in multiple batches manually, which increases the labor intensity of the workers.

Detailed Embodiment

[0019] 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.

[0020] Refer to Figures 1 - 4, a blank material recycling device, including a retaining frame 1. Vertical support legs 2 are fixedly connected to the four corners of the retaining frame 1. Axial holes one are provided on the front and rear side walls of the retaining frame 1, and bearings one are fixedly arranged in the axial holes one. A rotating shaft one 3 is fixedly inserted into the two bearings one together. The rear end of the rotating shaft one 3 extends backward out of the retaining frame 1. A blank turning roller 4 located inside the retaining frame 1 is fixedly sleeved on the outer wall of the rotating shaft one 3. The distance between the front and rear outer walls of the blank turning roller 4 and the inner side wall of the retaining frame 1 is less than the minimum size in the mixed blank materials. Two blank turning grooves 5 are symmetrically provided on the outer wall of the blank turning roller 4. The blank turning grooves 5 are used for transporting blank materials. Slot one is provided on the left and right side walls of the retaining frame 1, and inserting plates 6 are slidably inserted into the slot one. A fixing plate one 7 is fixedly connected to the outer end of the inserting plate 6. The fixing plate one 7 is fixedly connected to the outer wall of the retaining frame 1, that is, the inserting plate 6 is fixed to the retaining frame 1 through the fixing plate one 7. A guiding plate 8 located on one side of the blank turning roller 4 is fixedly connected to the inner end of the inserting plate 6. The guiding plate 8 is inclined. Both guiding plates 8 are in sliding contact with the outer wall of the blank turning roller 4. When sorting two kinds of blank materials, the mixed blank materials are centrally placed between the two guiding plates 8 in the retaining frame 1. By driving the blank turning roller 4 to rotate, the blank turning roller 4 slides along the end of the guiding plate 8. When the notch 5 of the blank turning groove 5 is located between the two guiding plates 8, the mixed blank materials will fall into the blank turning groove 5 until the blank turning groove 5 is filled. The blank materials in the blank turning groove 5 will be flipped with the blank turning roller 4.

[0021] Horizontal support rods 9 are fixedly arranged on the outer walls of the support legs 2. Axial holes two are provided on the support rods 9, and bearings two are fixed in the axial holes two. A rotating shaft two 11 is fixedly inserted into each of the bearings two. A turntable 10 is fixedly connected to the lower end of the rotating shaft two 11. A vertical rotating shaft three is fixedly connected to the edge of the turntable 10. There are connecting plates 12 symmetrically on the left and right sides of the lower side of the retaining frame 1 and located between the support legs 2. Axial sleeves 13 are fixed to the front and rear ends of the connecting plates 12. The axial sleeves 13 are movably sleeved on the corresponding rotating shafts three. A limiting plate located below the corresponding axial sleeve 13 is fixedly connected to the lower end of the rotating shaft three to prevent the axial sleeve 13 from falling off. Retaining edges 14 are fixedly connected to the opposite side walls of the connecting plates 12. A sieve plate 15 located below the blank turning roller 4 is fixedly connected by the two retaining edges 14. The sieve plate 15 is inclined. When the turntables 10 rotate in the same direction, the turntables 10 will drive the corresponding rotating shafts three to perform eccentric circular motions, and at the same time, the sieve plate 15 will also perform eccentric motions. After the blank materials in the blank turning groove 5 fall onto the sieve plate 15, with the eccentric motion of the sieve plate 15, the blank materials will move relative to the sieve plate 15 due to their own inertia. The size of the sieve holes on the sieve plate 15 is between the sizes of the two kinds of blank materials, that is, the blank materials smaller than the sieve hole size will pass through the sieve plate 15 and fall to the lower side, and the blank materials larger than the sieve hole size will gradually slide towards the end of the sieve plate 15 with the movement of the sieve plate 15, finally realizing the separation and recycling of the mixed blank materials.

[0022] In order to improve the smoothness of rotation between the turning roller 4 and the material guide plate 8, two second slots 16 are symmetrically formed in the front side wall of the retaining frame 1, and a limiting groove 17 corresponding to the second slot 16 is formed in the rear inner side wall of the retaining frame 1. A plug rod 18 is movably inserted into one of the second slots 16, and the end of the plug rod 18 extends into the corresponding limiting groove 17. A second fixing plate located outside the retaining frame 1 is fixedly connected to the outer end of the plug rod 18, and the second fixing plate is fixedly connected to the outer wall of the retaining frame 1. A rubber plate 19 that is in frictional contact with the outer wall of the turning roller 4 is fixedly connected to the lower wall of the plug rod 18. During the rotation of the turning roller 4, the rubber plate 19 can extrude the blank material extending out of the turning groove 5 to make it move, avoiding the extrusion and collision between the blank material extending out of the turning groove 5 and the end of the material guide plate 8, and preventing damage to the machine or the blank material.

[0023] The rear end of the first rotating shaft 3 is fixedly connected to a first belt pulley 20 located outside the retaining frame 1. The upper end of one of the second rotating shafts 11 is fixedly connected to a second belt pulley 21 located above the support rod 9. Positioning plates 22 are fixedly connected to the lower ends of the support legs 2, and the positioning plates 22 are used for fixedly connecting to the ground to improve the stability of the support legs 2. The first belt pulley 20 and the second belt pulley 21 are respectively connected to a first belt motor and a second belt motor through belts. The rotation of the first belt pulley 20 and the second belt pulley 21 is realized by the first belt motor and the second belt motor. In this utility model, by rotating the turning groove 5 on the turning roller 4, the mixed blank materials of two specifications between the material guide plates 8 are transported to the lower sieve plate 15 one by one, and then the sieve plate 15 is used to separate and recycle the mixed blank materials, avoiding the need for manual feeding of the blank materials onto the sieve plate 15 multiple times and reducing the labor intensity of workers.

[0024] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
