Description

Technical Field

[0001] This utility model relates to the field of eraser processing technology, and in particular to an eraser conical surface processing device. Background Technology

[0002] Some existing pencil-shaped erasers are manufactured by first producing a cylindrical eraser, then using equipment to sharpen a tapered surface at one end to form a pencil shape. Current processing equipment is similar to an electric pencil sharpener. A worker holds a cylindrical eraser, inserts one end into the sharpener, sharpens the end to form a tapered surface, then removes the eraser and repeats the process with the next eraser to create pencil-shaped erasers. This type of processing relies on manual feeding, is labor-intensive, and has low efficiency. Utility Model Content

[0003] To address the shortcomings of existing processing equipment, such as high labor costs and low processing efficiency, this invention proposes a rubber eraser cone surface processing device that saves labor and improves processing efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An eraser conical surface processing device includes a base, a feeding mechanism, a peeling mechanism, a rotating mechanism, and a linear drive mechanism. Two feeding mechanisms are symmetrically arranged at both ends of the base with opposite discharge directions. Each feeding mechanism includes a storage box, a first electric push rod, a support plate, and grippers. The storage box is vertically fixed above the base, and multiple erasers are horizontally stacked in the storage box. A discharge port is located on one side of the lower end of the storage box. One end of the support plate is connected to the discharge port and horizontally fixed to the storage box. The first electric push rod is horizontally mounted on the other side of the lower end of the storage box. The output shaft of the first electric push rod can extend into the storage box to push the erasers to the support plate. The grippers are mounted on the support plate to lock the erasers. The peeling mechanism includes a sliding seat and two cutting heads. The sliding seat is slidably connected to the upper side of the base and moves between the two feeding mechanisms under the action of the linear drive mechanism. The two cutting heads are coaxially rotatably connected to opposite sides of the sliding seat and driven by the rotating mechanism. The two cutting heads are opposite to the discharge ports of the two feeding mechanisms.

[0006] With the above settings, the feeding mechanism automatically feeds and discharges materials, reducing manual labor. The linear drive mechanism drives the peeling mechanism to move back and forth between the two feeding mechanisms. While processing the eraser at one feeding mechanism, the other feeding mechanism uses the processing time to discharge and feed materials, locking the processing interval of the peeling mechanism, thereby improving processing efficiency.

[0007] Furthermore, the sliding seat includes a sliding seat body and a bracket. The sliding seat body is slidably connected to the upper side of the base, and the bracket is vertically fixedly connected to the upper side of the sliding seat body. A rotating shaft is coaxially fixedly connected between the two cutter heads. The rotating shaft passes through the upper end of the bracket and is rotatably connected to the bracket. The rotating mechanism is installed on the sliding seat body and is drivenly connected to the rotating shaft.

[0008] Furthermore, the rotating mechanism includes a driven wheel, a drive wheel, a belt, and a motor. The motor is mounted on the upper side of the sliding seat body and connected to the drive wheel. The driven wheel is coaxially fixedly connected to the rotating shaft, and the driven wheel and the drive wheel are connected by belt drive.

[0009] With the above setup, the motor drives the shaft to rotate via the drive wheel, belt, and driven wheel.

[0010] Furthermore, the linear drive mechanism includes a guide rail and a second electric push rod. The guide rail is fixedly connected to the upper side of the base, and the sliding seat body is slidably connected to the upper side of the base through the guide rail. The second electric push rod is installed parallel to one end of the guide rail and connected to the sliding seat body.

[0011] Furthermore, the processing equipment also includes a discharge plate, which is inclined and positioned below the output side of the support plate.

[0012] The above setup allows for the side output of erasers from the support plate, facilitating eraser collection.

[0013] Furthermore, the processing equipment also includes a connecting column, through which the discharge plate is fixedly connected to the upper side of the base.

[0014] Furthermore, the gripper includes two clamping blocks disposed on the upper side of the support plate and capable of opening and closing to the left and right, with an arc surface on the inner side of the clamping blocks adapted to the eraser.

[0015] With the above settings, after the gripper clamps the eraser, the eraser is positioned, making it easy for the cutter head to process it precisely. Attached Figure Description

[0021] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0022] like Figures 1 to 5 An eraser cone surface processing device includes a base 3, a feeding mechanism 4, a peeling mechanism 5, a rotating mechanism 6, and a linear drive mechanism 7. Two feeding mechanisms 4 are symmetrically arranged at both ends of the base 3, with opposite discharge directions. Each feeding mechanism 4 includes a storage box 41, a first electric push rod 42, a support plate 43, and grippers 44. The storage box 41 is vertically fixed above the base 3. Multiple erasers 9 are horizontally stacked in the storage box 41. A discharge port 8 is provided on one side of the lower end of the storage box 41. One end of the support plate 43 is connected to the discharge port 8 and horizontally fixed to the storage box 41. The first electric push rod 42 is horizontally installed on the other side of the lower end of the box 41. The output shaft of the first electric push rod 42 can extend into the storage box 41 to push the eraser 9 to the support plate 43. The gripper 44 is installed on the support plate 43 to lock the eraser 9. The peeling mechanism 5 includes a sliding seat 51 and two blades 52. The sliding seat 51 is slidably connected to the upper side of the base 3 and moves between the two feeding mechanisms 4 under the action of the linear drive mechanism 7. The two blades 52 are coaxially rotatably connected to opposite sides of the sliding seat 51 and are driven by the rotation mechanism 6. The two blades are opposite to the discharge ports 8 of the two feeding mechanisms 4.

[0023] With the above settings, the feeding mechanism 4 automatically feeds and discharges materials, reducing manual labor. The linear drive mechanism 7 drives the peeling mechanism 5 to move back and forth between the two feeding mechanisms 4. While processing the eraser 9 at one feeding mechanism 4, the other feeding mechanism 4 uses the processing time to discharge and feed materials, locking the processing interval of the peeling mechanism 5, thereby improving processing efficiency.

[0024] Figure 1The marking processing equipment has two feeding mechanisms 4 symmetrically arranged at the front and rear ends of the base 3. The discharge port 8 of the front feeding mechanism 4 faces backward, and the discharge port 8 of the rear feeding mechanism 4 faces forward. The discharge ports 8 on the front and rear sides are opposite each other. Each discharge port 8 is used to output a single eraser 9. The first electric push rod 42 on the front side is installed on the lower front side of the storage box 41, and the first electric push rod 42 on the rear side is installed on the lower rear side of the storage box 41. The output shaft of the first electric push rod 42 faces the discharge port 8. The upper side of the storage box 41 is open for easy addition of erasers. Eraser 9, the storage box 41 has a rectangular cross-section, the width of which matches the outer diameter of eraser 9, and the length of which matches the length of eraser 9. When the cylindrical erasers 9 are stably stacked in the storage box 41, each eraser 9 extends forward and backward. The output shaft of the first electric push rod 42 is aligned with the bottommost eraser 9. During feeding, the first electric push rod 42 pushes the bottommost eraser 9 to the upper side of the support plate 43, and the gripper 44 clamps the eraser 9 on the support plate 43. After the first electric push rod 42 retracts, the erasers 9 in the storage box 41 automatically fall down, as... Figure 1 The end of the eraser 9 on the support plate 43 protrudes outside the support plate 43, facilitating processing by the cutting head 52. The linear drive mechanism 7 drives in the forward and backward direction. The cutting head 52 is similar to an existing manual pencil sharpener. The end of the eraser 9 on the support plate 43 is aligned with the cutting head 52. After the rotating mechanism 6 drives the two cutting heads 52 to rotate, the linear drive mechanism 7 first drives the sliding seat 51 to move backward. The rear cutting head 52 approaches the rear eraser 9. After the end of the eraser 9 enters the cutting head 52, the cutting head 52 cuts the end of the eraser 9 into a cone shape, forming a conical surface, such as... Figure 4 The linear drive mechanism 7 drives the sliding seat 51 to move forward, and the cutter head 52 moves away from the rear eraser 9. The front cutter head 52 moves closer to the front eraser 9. After the end of the front eraser 9 enters the cutter head 52, the cutter head 52 cuts the end of the eraser 9 into a cone shape. While the cutter head 52 is processing the front eraser 9, the rear gripper 44 releases the eraser 9 on the support plate 43. The rear first electric push rod 42 pushes a new eraser 9 onto the support plate 43 and clamps it with the gripper 44 for the next processing. The eraser 9 that was originally on the support plate 43 is pushed off by the new eraser 9. After the front eraser 9 is processed, the linear drive mechanism 7 continues to drive the sliding seat 51 to move backward to process the rear eraser 9. Each time an eraser 9 is processed, the feeding mechanism 4 on the other side uses the processing interval to feed the eraser, thereby shortening the processing time of a single eraser 9 and improving processing efficiency.

[0025] As one implementation, the sliding seat 51 includes a sliding seat body 511 and a bracket 512. The sliding seat body 511 is slidably connected to the upper side of the base 3, and the bracket 512 is vertically fixedly connected to the upper side of the sliding seat body 511. A rotating shaft 53 is coaxially fixedly connected between the two cutter heads 52. The rotating shaft 53 passes through the upper end of the bracket 512 and is rotatably connected to the bracket 512. The rotating mechanism 6 is installed on the sliding seat body 511 and is connected to the rotating shaft 53 for transmission.

[0026] The rotating shaft 53 of this application extends in the front-to-back direction and is coaxially fixedly connected between the two cutter heads 52. A bearing is installed between the rotating shaft 53 and the bracket 512 to reduce the rotational resistance of the rotating shaft 53. The rotating mechanism 6 drives the two cutter heads 52 to rotate synchronously through the rotating shaft 53.

[0027] In one implementation, the rotating mechanism 6 includes a driven wheel 61, a drive wheel 62, a belt 63, and a motor 64. The motor 64 is mounted on the upper side of the sliding seat body 511 and connected to the drive wheel 62. The driven wheel 61 is coaxially fixedly connected to the rotating shaft 53, and the driven wheel 61 and the drive wheel 62 are connected by the belt 63 for transmission.

[0028] With the above configuration, the motor 64 drives the rotating shaft 53 to rotate via the drive wheel 62, belt 63, and driven wheel 61.

[0029] As one implementation, the linear drive mechanism 7 includes a guide rail 71 and a second electric push rod 72. The guide rail 71 is fixedly connected to the upper side of the base 3, and the sliding seat body 511 is slidably connected to the upper side of the base 3 through the guide rail 71. The second electric push rod 72 is installed parallel to one end of the guide rail 71 and is connected to the sliding seat body 511.

[0030] The guide rail 71 of this application extends in the front-to-back direction and is located between the two feeding mechanisms 4. The sliding seat body 511 slides stably back and forth on the guide rail 71. The second electric push rod 72 is parallel to the guide rail 71 and is set on the front side of the guide rail 71. When the second electric push rod 72 extends, the sliding seat 51 moves backward. When it shortens, the sliding seat 51 moves forward. The movement distance of the sliding seat 51 can be controlled by a photoelectric sensor or a grating ruler, thereby controlling the processing depth of the cutter head 52.

[0031] As one implementation method, the processing equipment also includes a discharge plate 10, which is inclinedly arranged below the output side of the support plate 43.

[0032] The above configuration facilitates the side output of the eraser 9 from the support plate 43, so as to collect the eraser 9.

[0033] After the eraser 9 is processed, it is pushed off the support plate 43 and falls onto the inclined discharge plate 10. Under the action of gravity, the eraser 9 rolls laterally off the discharge plate 10. Figure 5This makes it convenient to collect erasers.

[0034] As one implementation method, the processing equipment also includes a connecting column 11, and the discharge plate 10 is fixedly connected to the upper side of the base 3 through the connecting column 11.

[0035] As one implementation, the gripper 44 includes two gripping blocks disposed on the upper side of the support plate 43 and capable of opening and closing to the left and right. The inner side of the gripping blocks is provided with an arc surface adapted to the eraser 9.

[0036] With the above settings, after the gripper 44 clamps the eraser 9, the eraser 9 is positioned, making it convenient for the cutter head 52 to process it precisely.

[0037] The gripper 44 of this application is electrically driven. The gripper 44 includes two clamping blocks that are set on the support plate 43. They can open and close left and right under the action of an electric cylinder or a screw and nut structure. When the two clamping blocks are closed, the eraser 9 can be clamped. When the two clamping blocks are separated, the eraser 9 can be released. The inner side of the clamping block is provided with an arc surface. When the eraser 9 is clamped, the arc surface is in contact with the outer peripheral surface of the eraser 9, so that the eraser 9 is precisely aligned with the cutter head 52 when it is clamped. After the cutter head 52 moves to the end of the eraser 9, the end of the eraser 9 can be precisely processed.

[0038] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
