DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Erasers are usually made of rubber, which has the plasticity and softness of rubber. When rubbed on paper, they can absorb wax particles and erase marks. After mixing, heating, pressing and other processes, erasers are usually in the form of long strips or sheets. Subsequently, a cutting device is usually required to cut the long strips or sheets of erasers into small pieces so that users can more easily grasp the eraser and erase accurately when writing or drawing. For the convenience of the eraser cutting device, you can cut erasers of different lengths. Please refer to Figure 1-Figure 4 , an embodiment provided by the utility model:

[0021] The invention discloses a block cutting device for processing erasers, wherein a conveying structure 1 is used for intermittently conveying a strip eraser, a lifting component 2 is installed on the conveying structure 1, two suspension frames 3 are detachably installed on both sides of the bottom of the lifting component 2, a splitting component 4 is installed between the two suspension frames 3 for cooperating with the lifting component 2 to cut the strip eraser, and a guide component 5 is installed at the bottom of the lifting component 2 for improving the balance of the splitting component 4. In actual application, the conveying structure 1 is used to convey the strip eraser placed flat on its upper surface to a set position directly below the splitting component 4 to pause the conveying, and then the lifting component 2 is used to drive the suspension frame 3 and the splitting component 4 to move downward, so as to achieve the purpose of cutting the strip eraser into blocks.

[0022] In order to increase the diversity of the length of the strip eraser cut, such as Figure 1 , Figure 2 and Figure 4As shown, the splitting assembly 4 includes a threaded rod 401 inserted between two suspension frames 3, a plurality of evenly arranged threaded sleeves 402 are sleeved on the outer surface of the threaded rod 401, a ring 403 is rotatably sleeved on the outer surface of the middle part of the threaded sleeve 402, a clamp 404 is installed at the bottom of the ring 403, and a tool 405 is detachably installed inside the clamp 404. The suspension frame 3 itself is disassembled and assembled by the upper half and the lower half, and the groove of the lower half is provided with a plug for inserting into the end of the threaded rod 401 to prevent the threaded rod 401 from rotating during use. In addition, when a rotational force is applied to the threaded sleeve 402, the threaded sleeve 402 rotates relative to the ring 403, and at the same time, it moves toward one side along the outer surface of the threaded rod 401, so as to achieve the purpose of adjusting the distance between two adjacent tools 405, thereby correspondingly changing the length of the long eraser after cutting, and improving the production adaptability for erasers of different sizes. A lever 4021 is installed on the outer surface of the threaded sleeve 402, and the top of the lever 4021 is spherical to avoid scratching the fingers of the staff. In addition, the application of the lever 4021 provides a fulcrum for rotating the threaded sleeve 402, reducing the difficulty of rotation.

[0023] Since the ring 403 and the threaded sleeve 402 are in a rotational connection state, when the cutter 405 cuts the eraser, the force fed back by the eraser to the cutter 405 will drive the cutter 405 to shake left and right. In order to improve the balance of the cutter 405 during cutting, Figure 3-Figure 4 As shown, the guide assembly 5 includes two upright plates installed at the bottom of the lifting assembly 2, and a guide rod 501 passing through a plurality of clamps 404 is inserted between the two upright plates. A fastening nut is sleeved on the tail end of the guide rod 501. The guide rod 501 is inserted into the clamp 404 to increase the friction between the threaded sleeve 402 on the clamp 404 and the threaded rod 401, making it difficult for the threaded sleeve 402 to move freely, thereby limiting the left and right shaking of the tool 405.

[0024] In order to clearly know the specific size of the distance between two adjacent cutting tools 405 when adjusting the distance between them, such as Figure 3-Figure 4 As shown, a scale rod 502 arranged in an N shape is sleeved on the guide rod 501, and the spacing between the outer sides of the two ends of the scale rod 502 is consistent with the spacing between the two upright plates, and a plurality of clamps 404 are installed with extended spring pieces 503 arranged in an L shape, and the rear wall of the extended spring piece 503 is in contact with the back of the scale rod 502, and an indicator arrow 504 for calibrating the scale rod 502 is installed on the extended spring piece 503. When the threaded sleeve 402 is rotated to move its position on the threaded rod 401, the extended spring piece 503 drives the indicator arrow 504 to follow the movement, and cooperates with the scale value on the scale rod 502, so as to achieve the purpose of calibrating the spacing value while adjusting the spacing of the tools 405.

[0025] like Figure 1 As shown, the lifting assembly 2 includes a supporting steel frame 201 installed on the conveying structure 1, on which a hydraulic cylinder 202 for driving the splitting assembly 4 to lift is installed, and the free end of the hydraulic cylinder 202 is installed with an integrated plate 203 assembled with the suspension frame 3 and the upright plate.

[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
