Description

Technical Field

[0001] The utility model relates to the technical field of paper cutters, and more specifically, to a high-speed paper cutter. Background Art

[0002] Paper cutters are traditional products used to handle the paper cutting requirements in the later stage of printing. They have developed from mechanical paper cutters to tape-controlled paper cutters, and then to microcomputer-programmed, color-display, full-image operation-guided visual processing, and computer-aided cutting external programming and editing production data cutting systems, which make the production preparation time shorter, the cutting accuracy higher, the labor intensity lower, and the operation safer.

[0003] However, the existing paper cutters have the following problems when in use:

[0004] (1) The paper transmission of traditional paper cutters may rely on manually arranging the paper and then placing it on a conveyor mechanism such as a conveyor belt or directly under the cutter for cutting. When the cutting distance of the paper needs to be adjusted, it is necessary to manually loosen the fixing parts such as the clamping blocks for fixing the paper, and then adjust the position of the paper. The process of manually adjusting the fixing parts is very time-consuming, especially in the case of frequent adjustment of the cutting distance, which will greatly reduce the production efficiency;

[0005] (2) Secondly, the operator is prone to fatigue due to long-term repetitive labor, which leads to a further decline in work efficiency. At the same time, it also increases the risk of errors, and adjusting the cutting distance of the paper under the cutter poses a certain safety risk to the operator and is prone to accidents.

[0006] The utility model can play a role that when adjusting the cutting position of the paper, the operator does not need to approach the cutter, and manual transportation by the operator is not required during transmission. Content of the Utility Model

[0007] The utility model aims to solve the technical problems proposed in the above background art and provides a high-speed paper cutter.

[0008] To achieve the above object, the utility model provides the following technical solution: A high-speed paper cutter, comprising: a workbench arranged under the cutter, a slide plate is slidably installed in the middle of the upper end of the workbench, side plates are arranged on both the left and right sides of the upper end of the slide plate, motors are fixedly installed at both the left and right ends of the workbench, a convex strip is fixedly installed in the middle of the upper end of the workbench, the convex strip is slidably connected with the slide plate, output slots are opened on both the left and right sides of the upper end of the workbench, the output slots are located at the bottom of the slide plate, fixing plates are arranged on both the left and right sides of the bottom of the slide plate, and the output slots are located at the bottom of the fixing plates.

[0009] Further preferred solution: A baffle is fixedly installed at the rear side of the upper end of the workbench. Electric telescopic rods I are fixedly installed on both the left and right sides of the front surface of the baffle. Push plates are fixedly installed at the output ends of the electric telescopic rods I. The left and right ends of the push plates are movably connected to the inner walls of the side plates.

[0010] Further preferred solution: Grooves are provided on both the left and right sides of the upper end of the sliding plate. Limit blocks are fixedly installed at the top of the front and rear sides inside the grooves. Tooth grooves are equidistantly provided at the bottom of the fixed plate. A chute I is provided in the middle of the bottom of the sliding plate. The chute I is slidably connected to the convex strip.

[0011] Further preferred solution: Side plates are embedded inside the grooves. Chutes II are provided at both the front and rear ends of the side plates. The chutes II are slidably connected to the limit blocks.

[0012] Further preferred solution: Electric telescopic rods II are fixedly installed at both the front and rear sides of the bottom of the side plates. The bottoms of the electric telescopic rods II are fixedly connected to the bottoms of the grooves. A plurality of screw holes I are provided above the outer end faces of the side plates.

[0013] Further preferred solution: Clamping plates are provided at the upper ends of the side plates. Screw holes II are provided at both the left and right ends of the clamping plates. The screw holes II are identical in structure to the screw holes I. The clamping plates are threadedly connected to the side plates through the screw holes II and the screw holes I.

[0014] Further preferred solution: Gears are fixedly installed at the output ends of the motors. The gears are arranged inside the output grooves. The gears are meshed with the bottom of the fixed plate.

[0015] Beneficial effects:

[0016] 1. By providing the electric telescopic rod I and the push plate, after the paper is placed on the sliding plate, when it is necessary to adjust the position of the paper in the front-rear direction, the electric telescopic rod I pushes the push plate forward. The push plate moves smoothly between the side plates. Due to the pushing action of the push plate, the paper is accurately pushed to the front end of the sliding plate, thereby realizing the precise positioning of the paper in the front-rear direction. This positioning function ensures that the position of the paper under the cutter is accurate, laying a foundation for subsequent precise cutting;

[0017] 2. By providing the convex strip, the output groove, the fixed plate, the motor and the gear, through the forward and reverse rotation of the motor and the meshing transmission of the gear and the tooth groove, the front-rear movement of the sliding plate on the workbench can be easily realized. The convex strip is slidably connected to the chute I at the bottom of the sliding plate, providing precise guidance for the movement of the sliding plate. The convex strip restricts the movement direction of the sliding plate, enabling it to move smoothly along a specific direction of the workbench only. This guiding function ensures that the sliding plate does not shift or shake during the movement, guaranteeing that the position of the paper under the cutter is accurate;

[0018] 3. In summary, this high-speed paper cutter is provided with structures such as a push plate, a side plate, a clamping plate and a gear. The electric telescopic rod pushes the push plate to accurately push the paper to the front end of the slide plate, so as to achieve accurate position adjustment of the paper in the front and rear directions, ensure the accuracy of the cutting position, and adapt to different cutting needs. Secondly, the side plate limits the paper in the left and right directions to prevent the paper from shifting during movement. The clamping plate can be fixed at different positions of the side plate according to the length of the paper. Through the adjustment of the electric telescopic rod 2, the paper can be tightly clamped to avoid undesirable phenomena such as paper displacement during the movement of the slide plate, thereby ensuring the stability of the paper during the cutting process. Finally, the gear engages with the tooth groove on the fixed plate at the bottom of the slide plate. Under the guidance of the convex strip, the slide plate is pushed to move smoothly and accurately on the upper end of the workbench, so that the paper can quickly and accurately reach the appropriate position under the cutter, and during cutting, the paper can be fine-tuned by the push plate to adjust the position where the paper is cut.

DETAILED DESCRIPTION

[0025] The following will be combined with the attached embodiment of the utility model Figures 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0026] See also Figures 1-5, in the embodiment of the present utility model, a high-speed paper cutter includes: a workbench 1 arranged below a cutter, a slide plate 2 is slidably installed in the middle of the upper end of the workbench 1, side plates 3 are arranged on both the left and right sides of the upper end of the slide plate 2, motors 4 are fixedly installed at both the left and right ends of the workbench 1, a convex strip 104 is fixedly installed in the middle of the upper end of the workbench 1, the convex strip 104 is slidably connected with the slide plate 2, output grooves 105 are opened on both the left and right sides of the upper end of the workbench 1, the output grooves 105 are located at the bottom of the slide plate 2, fixing plates 203 are arranged on both the left and right sides of the bottom of the slide plate 2, the output grooves 105 are located at the bottom of the fixing plates 203, a first chute 205 is opened in the middle of the bottom of the slide plate 2, the first chute 205 is slidably connected with the convex strip 104, tooth grooves 204 are equally spacedly opened at the bottom of the fixing plates 203, gear 401 is fixedly installed at the output end of each motor 4, the gear 401 is arranged inside the output groove 105, and the gear 401 meshes with the bottom of the fixing plate 203. Power is provided by the motors 4 at both ends of the workbench 1, and the gear 401 is fixedly installed at the output end of the motor 4. When the motor 4 operates, it drives the gear 401 to rotate. The gear 401 meshes and drives with the tooth groove 204. Since the gear 401 is arranged in the output groove 105 at the upper end of the workbench 1, and the tooth groove 204 is opened on the fixing plate 203 at the bottom of the slide plate 2, the gear 401 meshes with the tooth groove 204. When the gear 401 rotates, it pushes the slide plate 2 to move on the workbench 1 through the meshing action. A convex strip 104 is fixedly installed in the middle of the upper end of the workbench 1, and a first chute 205 matching the convex strip 104 is opened in the middle of the bottom of the slide plate 2. The sliding connection between the convex strip 104 and the first chute 205 provides a guiding function for the movement of the slide plate 2, ensuring that the slide plate 2 can move smoothly and accurately at the upper end of the workbench 1. When cutting paper, the paper to be cut is placed on the upper end of the slide plate 2, and the side plates 3 can provide a certain limit to the paper to prevent the paper from shifting during the movement. Then, the motors 4 at both the left and right ends of the workbench 1 are started. The motor 4 starts to operate and drives the gear 401 to rotate. Since the gear 401 meshes with the tooth groove 204 on the fixing plate 203 at the bottom of the slide plate 2, the rotation of the gear 401 pushes the slide plate 2 to move on the workbench 1. Under the guiding action of the convex strip 104 and the first chute 205, the slide plate 2 moves smoothly along a specific direction at the upper end of the workbench 1. When the slide plate 2 moves to a suitable position below the cutter, the cutter cuts the paper. After the cutting is completed, the motor 4 rotates in the reverse direction to retract the slide plate 2 and recycle the cut paper.

[0027] In the embodiment of the present utility model, a baffle 101 is fixedly installed at the rear side of the upper end of the workbench 1. Electric telescopic rods 102 are fixedly installed on both the left and right sides of the front surface of the baffle 101. Push plates 103 are fixedly installed at the output ends of the electric telescopic rods 102. The left and right ends of the push plates 103 are movably connected to the inner walls of the side plates 3. The baffle 101, the electric telescopic rods 102 and the push plates 103 at the rear side of the upper end of the workbench 1 form a paper positioning assistance system. When the paper is placed on the sliding plate 2 and the cutting position needs to be changed, the electric telescopic rods 102 can push the push plates 103 to move forward. The push plates 103 move between the side plates 3, thereby pushing the paper towards the front end of the sliding plate 2, enabling the paper to move on the sliding plate 2, realizing the positioning of the paper in the front-back direction, changing the position of the paper under the cutter, and realizing the change of the cutting position.

[0028] In the embodiment of the present utility model, grooves 201 are formed on both the left and right sides of the upper end of the sliding plate 2. Limit blocks 202 are fixedly installed at the top ends of the front and rear sides inside the grooves 201. Side plates 3 are embedded inside the grooves 201. Slide grooves 302 are formed at the front and rear ends of the side plates 3. The slide grooves 302 are slidably connected to the limit blocks 202. Electric telescopic rods 301 are fixedly installed at the front and rear sides of the bottom of the side plates 3. The bottoms of the electric telescopic rods 301 are fixedly connected to the bottoms of the grooves 201. A number of first screw holes 303 are formed above the outer end faces of the side plates 3. A clamping plate 304 is arranged at the upper end of the side plates 3. Second screw holes 305 are formed at both the left and right ends of the clamping plate 304. The second screw holes 305 are identical in structure to the first screw holes 303. The clamping plate 304 is threadedly connected to the side plates 3 through the second screw holes 305 and the first screw holes 303. The side plates 3 are adjusted to move up and down through the electric telescopic rods 301 inside the grooves 201. When the electric telescopic rods 301 expand and contract, they drive the side plates 3 to move up and down inside the grooves 201. The slide grooves 302 at the front and rear ends of the side plates 3 are slidably connected to the limit blocks 202 inside the grooves 201, ensuring the stability and linearity of the side plates 3 during the up and down movement, and ensuring that the side plates 3 will not be disengaged from the grooves during the movement. The first screw holes 303 above the outer end faces of the side plates 3 and the second screw holes 305 at both the left and right ends of the clamping plate 304 cooperate, and the clamping plate 304 can be fixed at different positions on the side plates 3 through bolt connection to adapt to different fixing points of papers with different lengths. During use, the paper is placed on the sliding plate 2, and then according to the length of the paper, the clamping plate 304 is fixed at different positions on the side plates 3 through the first screw holes 303 and the second screw holes 305. Then the electric telescopic rods 301 are started, and the side plates 3 are pulled downward. The side plates 3 move downward through the sliding connection between the slide grooves 302 and the limit blocks 202. When moving a certain distance, the bottom of the clamping plate 304 contacts the paper, fixing and limiting the paper to prevent the paper from shifting when the sliding plate 2 moves.

[0029] Working principle: When using a paper cutter to cut paper, first place the paper on the sliding plate 2. The side plates 3 limit the paper in the left-right direction to prevent the paper from shifting left or right during movement. According to the length of the paper, fix the clamping plate 304 at an appropriate position on the side plate 3 through the first screw hole 303 and the second screw hole 305. Then drive the second electric telescopic rod 301 to drive the side plate 3 to move downward in the groove 201. When the side plate 3 moves downward a certain distance, the bottom of the clamping plate 304 contacts the paper and clamps and limits the paper to prevent the paper from shifting when the sliding plate 2 moves. Then drive the motor 4. The rotation of the motor 4 drives the gear 401 to rotate. The gear 401 meshes with the tooth groove 204 on the bottom fixing plate 203 of the sliding plate 2. The rotation of the gear 401 pushes the sliding plate 2 to move above the workbench 1. Under the guiding action of the convex strip 104 and the first sliding groove 205, the sliding plate 2 moves smoothly along a specific direction at the upper end of the workbench 1. When the sliding plate 2 moves to an appropriate position below the cutting knife, the cutting knife cuts the paper; when it is necessary to change the cutting position of the paper, first slide the sliding plate 2 below the cutting knife, then drive the second electric telescopic rod 301 to move upward to cancel the restriction of the clamping plate 304 on the paper. Then drive the first electric telescopic rod 102 to make the push plate 103 move forward in the side plate 3. The push plate 103 pushes the paper to the front end of the sliding plate 2 to achieve the positioning of the paper in the front-back direction and change the position of the paper under the cutting knife. After cutting is completed, the motor 4 rotates in the reverse direction to retract the sliding plate 2 and recycle the cut paper. If it is necessary to continue cutting the paper, repeat the above steps.
